direction. The first folding plate may be disposed at the first
edge of the substrate. The second folding plate may be disposed at
the second edge of the substrate. The first clamping portion may
include a first sidewall and a protruding portion. The first
sidewall of the first clamping portion may be connected to the
first folding plate. The protruding portion of the first clamping
portion may protrude from the first sidewall and protrude towards
the second edge of the substrate in the first direction. The second
clamping portion may have a trench concave towards the second
folding plate.
[0007] In one or more implementations of the present disclosure,
when the first folding plate and the second folding plate are
respectively folded towards the second surface of the substrate, a
gap may be respectively formed between the first clamping portion
and the annular wall and between the second clamping portion and
the annular wall.
[0008] In one or more implementations of the present disclosure,
the cushioning apparatus may further include two pressing portions.
The pressing portions may be disposed on the first folding plate
and the second folding plate respectively. One of the pressing
portions may be located on a side, far away from the second
clamping portion, of the first clamping portion. The other pressing
portion may be located on a side, far away from the first clamping
portion, of the second clamping portion. When the first folding
plate and the second folding plate are folded respectively towards
the second surface of the substrate, the pressing portions may
press against the annular wall respectively.
[0009] In one or more implementations of the present disclosure,
each pressing portion may have a top surface far away from the
first folding plate and the second folding plate. The top surface
of the pressing portion may be configured to press against the
annular wall. A contour of the top surface of the pressing portion
may be complementary to a partial outer surface of the annular
wall.
[0010] In one or more implementations of the present disclosure,
the cushioning apparatus may further include a first supporting
portion. The first supporting portion may be disposed on the first
folding plate and located on a same side as the second surface of
the substrate. The first supporting portion may be connected with
the first clamping portion and a corresponding one of the two
pressing portions.
[0011] In one or more implementations of the present disclosure,
the cushioning apparatus may further include a second supporting
portion. The second supporting portion may be disposed on the
second folding plate and located on a same side as the second
surface of the substrate. The second supporting portion may be
connected with the second clamping portion and the other one of the
two pressing portions.
[0012] In one or more implementations of the present disclosure,
the first folding plate may be concave towards the second surface
to form a first cushioning space. The second folding plate may be
concave towards the second surface to form a second cushioning
space. The first cushioning space and the second cushioning space
may be respectively aligned with the first clamping portion and the
second clamping portion.
[0013] In conclusion, the first clamping portion on the first
folding plate and the second clamping portion on the second folding
plate of the present disclosure may be clamped with each other
after the first folding plate and the second folding plate are
folded, so that folded states of the first folding plate and the
second folding plate can be kept and the structural stability of
the cushioning apparatus can be improved. In this way, the first
folding plate and the second folding plate may be perpendicular to
the substrate to suffer impact in at least a first direction and/or
a second direction, so as to ensure that the cushioning apparatus
can achieve a cushioning effect.
BRIEF DESCRIPTION OF THE DRAWINGS
[0014] FIG. 1A and FIG. 1B are respectively a top view and a bottom
view of a cushioning apparatus in a deployed state according to an
implementation of the present disclosure;
[0015] FIG. 2A and FIG. 2B are respectively three-dimensional
diagrams of a cushioning apparatus in a folding process according
to an implementation of the present disclosure; and
[0016] FIG. 2C is a three-dimensional diagram of the structure in

DETAILED DESCRIPTION
[0017] The following descriptions provide various different
implementations or embodiments to implement the subject of the
present disclosure. Specific examples of elements or arrangements
are discussed below to simplify the present disclosure. Certainly,
the plurality of descriptions is only some examples and the present
disclosure is not limited thereto. For example, a description that
a first feature is formed on or above a second feature includes an
implementation in which the first feature and the second feature
directly contact and also includes an implementation in which
another feature is formed between the first feature and the second
feature and the first feature and the second feature do not
directly contact in this case. In addition, numerals or texts may
be repeated in different examples in the present disclosure. The
objective of repetition is to simplify and clarify descriptions
rather than to define a relationship between the discussed
different implementations and configurations.
[0018] In addition, the terms "under", "below", "lower", "on",
"above", and other similar terms representing spatial relativity
are used herein to easily describe a relationship between an
element or a feature and another element or feature in the
drawings. The terms representing spatial relativity should cover
orientations depicted in the drawings and further cover other
orientations during the use or operation of an apparatus. That is,
when the orientation of the apparatus is different from that in the
accompanying drawings (rotation by 90 degrees or in another
orientation), the terms representing spatial relativity used in
this specification may also be correspondingly explained.
[0019] FIG. 1A and FIG. 1B are respectively a top view and a bottom
view of a cushioning apparatus 1 in a deployed state according to
an implementation of the present disclosure. As shown in FIG. 1A
and FIG. 1B, in this implementation, the cushioning apparatus 1
includes a substrate 12, a first folding plate 13a, a second
folding plate 14a, a third folding plate 13b, a fourth folding
plate 14b, an annular wall 15, first clamping portions 16a1 and
16a2, second clamping portions 17a1 and 17a2, pressing portions 18,
a first supporting portion 19 (see FIG. 1B), a second supporting
portion 20, and a supporting bottom plate 22. In addition, in some
implementations, a material of the cushioning apparatus 1 is a
plastic material. In other implementations, the cushioning
apparatus 1 has a paper plastic structure. The structures and
functions of the elements and connection relationships between the
elements are described below in detail.
[0020] In FIG. 1A and FIG. 1B, the substrate 12 has a rectangular
plate body and has a first surface 10 and a second surface 11
opposite to each other. Further, the substrate 12 has a first edge
120a, a second edge 122a, a third edge 120b, and a fourth edge
122b. The first edge 120a and/or the third edge 120b of the
substrate 12 intersects with the adjacent second edge 122a and
fourth edge 122b and respectively extends in a first direction D1.
The second edge 122a and the fourth edge 122b of the substrate 12
respectively extend in a second direction D2. In some
implementations, the first direction D1 intersects with the second
direction D2. In this implementation, the first direction D1 is
perpendicular to the second direction D2.
[0021] In some implementations, the annular wall 15 and the
supporting bottom plate 22 are formed through molding of a plastic
material. In some implementations, the annular wall 15 and the
supporting bottom plate 22 are formed by stamping the substrate 12.
Furthermore, the annular wall 15 and the supporting bottom plate 22
are concave in the substrate 12 towards the second surface 11 from
the first surface 10. In other words, the annular wall 15 protrudes
from the second surface 11 from the substrate 12 (see FIG. 1B). An
outer edge of the supporting bottom plate 22 contacts and is
connected with an end, far away from the substrate 12, of the
annular wall 15. In this implementation, the supporting bottom
plate 22 has a circular plate body, but the present utility model
is not limited thereto. The annular wall 15 and the supporting
bottom plate 22 form an accommodation space 150 together (see FIG.
1A). In other words, the substrate 12 further has the accommodation
space 150. The accommodation space 150 is concave towards the
second surface 11 from the first surface 10. The annular wall 15 is
disposed around the accommodation space 150. The accommodation
space 150 in this implementation is used to accommodate an item
(not shown) that requires shock absorption.
[0022] In FIG. 1A and FIG. 1B, the first folding plate 13a and the
third folding plate 13b respectively extend in a direction away
from the substrate 12 from the first edge 120a and the third edge
120b and are configured to respectively rotate with respect to the
substrate 12 towards the annular wall 15 based on the first edge
120a and the third edge 120b of the substrate 12. Specifically, the
first folding plate 13a and the third folding plate 13b are
respectively disposed at the first edge 120a and the third edge
120b of the substrate 12. The first folding plate 13a is adjacent
to and located between the second folding plate 14a and the fourth
folding plate 14b. The third folding plate 13b is adjacent to and
located between the second folding plate 14a and the fourth folding
plate 14b. Similarly, the second folding plate 14a and the fourth
folding plate 14b respectively extend in a direction away from the
substrate 12 from the second edge 122a and the fourth edge 122b and
are configured to respectively rotate with respect to the substrate
12 towards the annular wall 15 based on the second edge 122a and
the fourth edge 122b of the substrate 12. In detail, the second
folding plate 14a and the fourth folding plate 14b are respectively
disposed at the second edge 122a and the fourth edge 122b of the
substrate 12. The second folding plate 14a is adjacent to and
located between the first folding plate 13a and the third folding
plate 13b. The fourth folding plate 14b is adjacent to and located
between the first folding plate 13a and the third folding plate
13b. In this implementation, folding lines are disposed at
positions of the first edge 120a, the second edge 122a, the third
edge 120b, and the fourth edge 122b. However, the present
disclosure is not limited thereto. For example, in other
implementations, all structural configurations are applicable to
the present disclosure provided that the first folding plate 13a
can rotate towards the annular wall 15 with respect to the
substrate 12.
[0023] In FIG. 1A and FIG. 1B, the first clamping portions 16a1 and
16a2, a plurality of pressing portions 18 (where two pressing
portions 18 are shown in the figures), and a plurality of first
supporting portions 19 (where three first supporting portions 19
are shown in the figures) are disposed on the first folding plate
13a. The first clamping portions 16a1 and 16a2, the plurality of
pressing portions 18, and the plurality of first supporting
portions 19 are located on a same side of the first folding plate
13a as the second surface 11 of the substrate 12. Furthermore, the
first folding plate 13a is concave towards the second surface 11 to
form a first cushioning space 164 (see FIG. 1A) and a first
cushioning space 166 (see FIG. 1A), and forms the first clamping
portions 16a1 and 16a2. The first cushioning space 164 is aligned
with the first clamping portion 16a1, and the first cushioning
space 166 is aligned with the first clamping portion 16a2. In some
implementations, the first clamping portions 16a1 and 16a2, the
pressing portions 18, and the first supporting portions 19 are
formed through molding of a plastic material. In some
implementations, the first clamping portions 16a1 and 16a2, the
pressing portions 18, and the first supporting portions 19 that are
located on the first folding plate 13a are formed by stamping the
first folding plate 13a. Similarly, the pressing portions 18 and
the first supporting portions 19 are formed by concaving the first
folding plate 13a.
[0024] Specifically, the first clamping portion 16a1 and the first
clamping portion 16a2 are respectively located at two ends of the
first folding plate 13a in the first direction D1. Furthermore, the
first clamping portion 16a1 includes a first sidewall 160 and a
protruding portion 162. The first sidewall 160 of the first
clamping portion 16a1 is connected to and protrudes from the first
folding plate 13a. The protruding portion 162 of the first clamping
portion 16a1 protrudes from the first sidewall 160, and protrudes
towards the second edge 122a of the substrate 12 in the first
direction D1. The first clamping portion 16a2 in this
implementation is substantially the same as the first clamping
portion 16a1. Accordingly, the structure and function of the first
clamping portion 16a2 and the connections between the first
clamping portion 16a2 and other elements can be understood with
regard to the related descriptions of the first clamping portion
16a1. Details are not described herein again.
[0025] In this implementation, each pressing portion 18 has a top
surface 180 (see FIG. 1B) far away from the first folding plate
13a. The top surface 180 of the pressing portion 18 is configured
to press against the annular wall 15. In some implementations, a
contour of the top surface 180 of the pressing portion 18 is
complementary to a partial outer surface of the annular wall 15. On
the first folding plate 13a, the pressing portion 18 is located
between the first clamping portion 16a1 and the first clamping
portion 16a2. In other words, on the first folding plate 13a, one
of the pressing portions 18 is located on a side, far away from the
second clamping portion 17a1, of the first clamping portion 16a1.
In addition, on the first folding plate 13a, one of the first
supporting portions 19 is connected between the first clamping
portion 16a1 and the pressing portion 18. Another one of the first
supporting portions 19 is connected between the first clamping
portion 16a2 and the pressing portion 18. The third one of the
first supporting portions 19 is connected between two adjacent
pressing portions 18. In this way, the first supporting portion 19
can improve the overall structural strength.
[0026] It should be noted that the third folding plate 13b in this
implementation and the elements located on the third folding plate
13b are substantially the same as the first folding plate 13a and
the first clamping portions 16a1 and 16a2, the pressing portions
18, and the first supporting portions 19 that are located on the
first folding plate 13a. The structures and functions of the
plurality of elements and the connections between the elements can
be understood with regard to the foregoing related descriptions.
Details are not described herein again.
[0027] In FIG. 1A and FIG. 1B, the second clamping portions 17a1
and 17a2, a plurality of pressing portions 18 (where two pressing
portions 18 are shown in the figures), and a plurality of second
supporting portions 20 (where three second supporting portions 20
are shown in the figures) are disposed on the second folding plate
14a. The second clamping portions 17a1 and 17a2, the plurality of
pressing portions 18, and the plurality of second supporting
portions 20 are located on a same side of the second folding plate
14a as the second surface 11 of the substrate 12. In some
implementations, the second clamping portions 17a1 and 17a2, the
pressing portions 18, and the second supporting portions 20 are
formed through molding of a plastic material. In some
implementations, the second clamping portions 17a1 and 17a2, the
pressing portions 18, and the second supporting portions 20 that
are located on the second folding plate 14a are formed by stamping
the second folding plate 14a. Furthermore, the second folding plate
14a is concave towards the second surface 11 to form a second
cushioning space 174 (see FIG. 1A) and a second cushioning space
176 (see FIG. 1A) and to form the second clamping portions 17a1 and
17a2. The second cushioning space 174 is aligned with the second
clamping portion 17a1, and the second cushioning space 176 is
aligned with the second clamping portion 17a2. Similarly, the
pressing portions 18 and the second supporting portions 20 are
formed by concaving the second folding plate 14a.
[0028] Specifically, the second clamping portion 17a1 and the
second clamping portion 17a2 are respectively located at two ends
of the second folding plate 14a in the second direction D2.
Furthermore, the second clamping portion 17a1 has a trench 170. The
trench 170 of the second clamping portion 17a1 is concave towards
the second folding plate 14a. The second clamping portion 17a2 in
this implementation is substantially the same as the second
clamping portion 17a1. Accordingly, the structure and function of
the second clamping portion 17a2 and the connections between the
second clamping portion 17a2 and other components can be understood
with regard to the related descriptions of the second clamping
portion 17a1. Details are not described herein again.
[0029] In this implementation, the pressing portions 18 located on
the second folding plate 14a is substantially the same as the
pressing portions 18 located on the first folding plate 13a.
Accordingly, the structure and function of the pressing portion 18
located on the second folding plate 14a and the connections between
the elements can be understood with regard to the foregoing related
descriptions. Details are not described herein again. It needs to
be described herein that on the second folding plate 14a, the
pressing portions 18 is located between the second clamping portion
17a1 and the second clamping portion 17a2. In other words, on the
second folding plate 14a, one of the pressing portions 18 is
located on a side, far away from the first clamping portion 16a1,
of the second clamping portion 17a1. In addition, on the second
folding plate 14a, one of the second supporting portions 20 is
connected between the second clamping portion 17a1 and the pressing
portion 18. Another one of the second supporting portions 20 is
connected between the second clamping portion 17a2 and the pressing
portion 18. The third one of the second supporting portions 20 is
connected between two adjacent pressing portions 18. In this way,
the second supporting portions 20 can improve the overall
structural strength.
[0030] It should be noted that, the fourth folding plate 14b in
this implementation and the elements located on the fourth folding
plate 14b are substantially the same as the second folding plate
14a and the second clamping portions 17a1 and 17a2, the pressing
portions 18, and the second supporting portions 20 that are located
on the second folding plate 14a. The structures and functions of
the plurality of elements and the connections between the elements
can be understood with regard to the foregoing related
descriptions. Details are not described herein again.
[0031] FIG. 2A and FIG. 2B are respectively three-dimensional
diagrams of a cushioning apparatus 1 in a folding process according
to an implementation of the present disclosure.
[0032] In FIG. 2A, in some implementations, when the first folding
plate 13a is folded towards the second surface 11 of the substrate
12, the first clamping portion 16a1 located on the first folding
plate 13a is clamped to the second clamping portion 17a1 located on
the second folding plate 14a. Specifically, in this implementation,
the first folding plate 13a rotating towards the annular wall 15
with respect to the substrate 12 makes the first clamping portion
16a1 located on the first folding plate 13a clamped to the second
clamping portion 17a1 located on the second folding plate 14a that
is already folded. In some implementations, when the first folding
plate 13a is folded towards the second surface 11 of the substrate
12, the pressing portions 18 located on the first folding plate 13a
respectively press against the annular wall 15, and a gap is formed
between the first clamping portion 16a1 and the annular wall 15.
Specifically, the first folding plate 13a rotates 12 towards the
annular wall 15 with respect to the substrate until the pressing
portions 18 presses against the annular wall 15. In this case, a
gap is formed between the first clamping portion 16a1 and the
annular wall 15.
[0033] Next, in FIG. 2B, in some implementations, when the second
folding plate 14a is folded towards the second surface 11 of the
substrate 12, the second clamping portion 17a1 located on the
second folding plate 14a is clamped to the first clamping portion
16a1 located on the first folding plate 13a. Specifically, in this
implementation, the second folding plate 14a rotating towards the
annular wall 15 with respect to the substrate 12 makes the second
clamping portion 17a1 located on the second folding plate 14a
clamped to the first clamping portion 16a1 on the first folding
plate 13a that is already folded. In some implementations, when the
second folding plate 14a is folded towards the second surface 11 of
the substrate 12, the pressing portions 18 located on the second
folding plate 14a respectively press against the annular wall 15,
and a gap is formed between the second clamping portion 17a1 and
the annular wall 15. Specifically, the second folding plate 14a
rotates towards the annular wall 15 with respect to the substrate
12 until the pressing portions 18 press against the annular wall
15. In this case, the trench 170 (see FIG. 2A) of the second
clamping portion 17a1 is clamped to the protruding portion 162 (see
FIG. 2A) of the first clamping portion 16a1 to allow the protruding
portion 162 to be located in the trench 170, so that the protruding
portion 162 and the trench 170 are fixed to each other. In this
implementation, a gap is formed between the second clamping portion
17a1 and the annular wall 15 to form a cushioning space. In this
way, when the cushioning apparatus 1 takes impact, the second
clamping portion 17a1 and the first clamping portion 16a1 may
maintain the clamping state, thereby improving the structural
stability of the cushioning apparatus 1.
[0034] FIG. 2C is a three-dimensional diagram of the structure in
FIG. 2B from another angle. In FIG. 2C, in this implementation, an
accommodated item (not shown) may be disposed in the accommodation
space 150 in the annular wall 15. Because a concave groove
structure is provided on a lateral surface of the folded cushioning
apparatus 1, cushioning distances when the accommodated item takes
impact in at least the first direction D1 and/or the second
direction D2 may be increased. Accordingly, the structural strength
of the cushioning apparatus 1 can be improved without increasing a
material thickness of the cushioning apparatus 1, so as to prevent
the accommodated item from damage due to impact.
[0035] In addition, the first clamping portion 16a1 (see FIG. 2B)
on the first folding plate 13a and the second clamping portion 17a1
(see FIG. 2B) on the second folding plate 14a may be clamped to
each other after the first folding plate 13a and the second folding
plate 14a are folded, so that the first folding plate 13a and the
second folding plate 14a can maintain the folded states, and the
structural stability of the cushioning apparatus 1 is improved.
Accordingly, the first folding plate 13a and the second folding
plate 14a may be substantially perpendicular to the substrate 12 to
take impact in at least the first direction D1 and/or the second
direction D2, so as to ensure that the cushioning apparatus 1 can
achieve a cushioning effect.
[0036] Moreover, a force may be transferred between the first
folding plate 13a and the second folding plate 14a by clamping the
first clamping portion 16a1 and the second clamping portion 17a1,
so as to improve a cushioning capability of the cushioning
apparatus 1 under impact. For example, when an external force is
applied to the first folding plate 13a, a stress from the external
force may be transferred to the second folding plate 14a through
the connection between the first clamping portion 16a1 (see FIG.
2B) and the second clamping portion 17a1 (see FIG. 2B).
Accordingly, excessive bending of the first folding plate 13a due
to the concentration of the stress on the first folding plate 13a
can be prevented, so that a cushioning effect of the cushioning
apparatus 1 can be improved.
[0037] In addition, because the first clamping portions 16a1 and
16a2 and the second clamping portions 17a1 and 17a2 (see FIG. 2B)
respectively contain cushioning spaces 164, 166, 174, and 176, and
the cushioning spaces 164, 166, 174, and 176 can improve the
structural flexibility of the first clamping portions 16a1 and 16a2
and the second clamping portions 17a1 and 17a2, the first clamping
portions 16a1 and 16a2 and the second clamping portions 17a1 and
17a2 can absorb a relatively large amount of impact energy under
impact, so as to protect the accommodated item located in the
cushioning apparatus 1.
[0038] Moreover, the pressing portions 18 (see FIG. 2B) in this
implementation press against the annular wall 15 after folded.
Accordingly, when the cushioning apparatus 1 is impacted, the
pressing portions 18 may help to transfer a stress from the first
folding plate 13a, the third folding plate 13b (see FIG. 2B), the
second folding plate 14a, and/or the fourth folding plate 14b to
the annular wall 15, and further to transfer the stress to the
substrate 12. In addition, a contour of the pressing portions 18 is
complementary to a partial outer surface of the annular wall 15 for
complete contact, so that the efficiency of stress transfer can be
improved, thereby further improving the cushioning effect of the
cushioning apparatus 1.
