Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application is based on and claims priority to Chinese
Patent Application No. 201921858519.8, filed on Oct. 31, 2019, the
contents thereof being incorporated by reference in their entirety
herein.
TECHNICAL FIELD
[0002] The present disclosure relates to the technical field of
electronic devices and, in particular, to a support frame and an
electronic sign.
BACKGROUND
[0003] Some conference signs are conventionally placed on a desktop
to show names of people in corresponding positions or other
information. The conference signs are generally double-sided. As
shown in FIG. 1, a conventional conference sign is formed by a
support frame 10 and a piece of folded paper 11, on both sides of
which a name is written (this name may be in the dashed box in FIG.
1), and are respectively attached to both sides of the support
frame 10, so that participants can sit in the correct seats and
recognize each other. In terms of a single conference sign, it has
a low cost and can be easily replaced, but if there are many
participants, it is required to print the name of each of the
participants and replace conference signs one by one, which wastes
a lot of manpower and is easy for conference signs to be mistakenly
placed.
[0004] At present, in order to improve the above situation, an
electronic sign with a double-sided display is generally used to
replace the conventional conference sign. In this case, contents
displayed in the electronic sign can be replaced in an electronic
controlling manner, which is fast to be replaced and reduces use of
papers. However, a single-screen in the electronic sign is
difficult to be disassembled or easy to fall off.

[0038] An embodiment of the present disclosure provides an
electronic sign, which belongs to a display device. As shown in
FIG. 2, the electronic sign may include a support frame 20, a first
display structure 30, and a second display structure 31. The first
display structure 30 and the second display structure 31 may be
mounted on opposite sides of the support frame 20, so that the
electronic sign has a double-sided display function. The electronic
sign may be used in a conference as a conference sign, but it is
not limited thereto, that is, it can also be used in public places
(for example, shopping malls, supermarkets, theaters) for releasing
business, financial, and entertainment information.
[0039] The electronic signs described in the embodiments of the
present disclosure will be described in detail below with reference
to the accompanying drawings.
[0040] As shown in FIG. 2, the first display structure 30 may
include a first display screen 301 and a first power supply portion
302 mounted on a back side of the first display screen 301. The
first power supply portion 302 is configured to supply power to the
first display screen 301. For example, the first display screen 301
and the first power supply portion 302 may be assembled together by
using a casing. Here, the casing may be a plastic casing to reduce
weight of the first display structure 30, but it is not limited
thereto. The first power supply portion 302 may be a battery
assembly, and the first display screen 301 may be an electronic ink
screen. The electronic ink screen may be controlled by an
electrical system, and may be specifically operated on a peripheral
terminal (for example, a computer) to replace the contents shown on
the electronic ink screen. The electronic ink screen only consumes
power while switching images, and hardly consumes power when
normally displaying, so that the electronic ink screen in this
embodiment is used as a display body to facilitate replacement of
display contents and also reduce costs and energy consumption of
the electronic signs.
[0041] As shown in FIG. 2, the second display structure 31 may
include a second display screen 311 and a second power supply
portion 312 mounted on the back side of the second display screen
311. The second power supply portion 312 is used to supply power to
the second display screen 311. It should be noted that a
specification of the second display structure 31 may be exactly the
same as a specification of the first display structure 30. The
second display screen 311 and the second power supply portion 312
may be assembled together using a casing, and the first power
supply portion 302 may be a battery assembly and the second display
screen 311 may be an electronic ink screen.
[0042] It should be noted that the aforementioned back side of the
display screen refers to a surface disposed opposite to the display
surface of the display screen.
[0043] As shown in FIG. 2 and FIG. 3, the support frame 20 may be
made of a metal material. This may ensure that the support frame 20
has a certain capacity of elastic memory, and thus facilitate its
deformation or return, while ensuring support stability of the
support frame 20. Specifically, the support frame 20 may include a
base with elasticity, a first support portion, and a second support
portion. The first support portion may include a first support
plate 201 and a first engaging portion (which may also be called
"first snap-fit portion", for example) 203, and the second support
portion includes a second support plate 202 and the second engaging
portion (which may also be called "second snap-fit portion", for
example) 204.
[0044] As shown in FIG. 2 and FIG. 3, a bottom end of the first
support plate 201 and a bottom end of the second support plate 202
are respectively connected to opposite ends of the base. A top end
of the first support plate 201 and a top end of the second support
plate 202 extend in a direction closing to each other, and are
disposed separately. The first engaging portion 203 is disposed on
a surface of the first support plate 201 facing away from the
second support plate 202, the second engaging portion 204 is
disposed on a surface of the second support plate 202 facing away
from the first support plate 201, and the first engaging portion
203 and the second engaging portion 204 may be respectively engaged
with (e.g., snapped-fit to) a display structure (or an electronic
sign, or other similar objects). Also, the display structure may be
inserted, pushed, or pressed into either of these engaging
portions. For example, the first engaging portion 203 may be
engaged with a first power supply portion 302 in the first display
structure 30, so that the first display structure 30 is mounted on
the first support portion. The second engaging portion 204 may be
engaged with a second power supply portion 312 in the second
display structure 31, so that the second display structure 31 is
mounted on the second support portion.
[0045] As the first power supply portion 302 and the second power
supply portion 312 are required to be replaced after use for a
certain period, when service life of the first display screen 301
and the second display screen 311 expires, or for other reasons,
the first display structure 30 and the second display structure 31
may need to be removed from the support frame 20 for replacement.
Thus, as compared with a solution in which the display structure is
mounted onto the support frame 20 in connection manners such as
screws and gluing, a solution in which the display structure is
mounted onto the support frame 20 by engaging the power supply
portion with the engaging portion in this embodiment, thereby
facilitating disassembly and assembly between the display structure
and the support frame 20, and improving disassembly and assembly
efficiency therebetween.
[0046] In addition, as shown in FIG. 2 and FIG. 3, as compared with
a solution in which the top end of the first support plate 501 is
connected with the top end of the second support plate 502 in the
related art (as shown in FIG. 6), the top end of the first support
plate 201 and the top end of the second support plate 202 in the
support frame 20 are designed to be disposed separately, to enhance
deformation and return capabilities of the first support plate 201
and the second support plate 202 in the support frame 20. This
design may not only facilitate the first display structure 30 and a
second display structure 31 to be detached from the support frame
20, and structural stability of the support frame 20 can also be
ensured.
[0047] Optionally, as shown in FIG. 2 and FIG. 3, the first
engaging portion 203 and the second engaging portion 204 are each
formed with an engaging space 205, the first power supply portion
302 may be engaged in the engaging space 205 of the first engaging
portion, and the second power supply portion 312 may be engaged in
the engaging space 205 of the second engaging portion. In order to
ensure stability of engagements between the first power supply
portion 302 and the first engaging portion and between the second
power supply portion 312 and the second engaging portion, in this
embodiment, a slot in engagement with a hook of the first engaging
portion 203 may be provided at a junction between the first power
supply portion 302 and the first display screen 301, and a slot in
engagement with a hook of the second engaging portion 204 is
provided at a junction between the second power supply portion 312
and the second display screen 311.
[0048] Optionally, the first engaging portion 203 may have an
inserting groove extending in a direction parallel to the first
support plate 201, so that the engaging structure of an object (for
example, a display structure or an electronic sign) may be inserted
into the engaging space 205 from either of both sides of the first
support plate 201. Optionally, the second engaging portion 204 may
also have an inserting groove extending in a direction parallel to
the second plate 202, so that the engaging structure of the object
(for example, a display structure or an electronic sign) is
inserted into the engaging space 205 from either of both sides of
the second support plate 202.
[0049] Optionally, each of the first engaging portion 203 and the
second engaging portion 204 is formed with a projection or recess,
so that the engaging structure of the object may be pressed onto
the first support plate and the second support plate through the
projection or the recess of the first engaging portion 203 and the
projection or the recess of the second engaging portion 204,
respectively.
[0050] It should be noted that, the first display screen 301 and
the first power supply portion 302 mentioned above may be connected
together through a casing, and the second display screen 311 and
the second power supply portion 312 may be connected together
through a casing. Therefore, the aforementioned slot may be formed
at a part of the casing corresponding to the junction between the
display screen and the power supply portion.
[0051] Further, as shown in FIG. 2 and FIG. 3, a surface of the
first support plate 201 at the engaging space 205 of the first
engaging portion 203 is a frosted surface 207 to increase its
frictional adhesion; similarly, a surface of the second support
plate 202 at the engaging space 205 of the second engaging portion
204 is the frosted surface 207 (a matte-treated surface) to
increase its frictional adhesion. In this way, when the first power
supply portion 302 is engaged in the engaging space 205 of the
first engaging portion 203, the first power supply portion 302 is
in contact with the frosted surface 207 on the first support plate
201 to increase friction force between the first power supply
portion 302 and the first support plate 201, such that the
situation that the first power supply portion 302 is detached from
the engaging space 205 of the first engaging portion 203 can be
alleviated, and assembly stability between the first display
structure 30 and the first support portion can be ensured.
Similarly, when the second power supply portion 312 is engaged in
the engaging space 205 of the second engaging portion 204, the
second power supply portion 312 is in contact with the frosted
surface 207 on the second support plate 202 to increase the
friction force between the second power supply portion 312 and the
second support plate 202, such that the situation that the second
power supply portion 312 is detached from the engaging space 205 of
the second engaging portion 204 can be alleviated, and assembly
stability between the second display structure 31 and the second
support portion can be ensured.
[0052] Optionally, as shown in FIG. 2 and FIG. 3, the base of the
support frame 20 has a bottom plate 208, a first buffer plate 209,
and a second buffer plate 210. The bottom plate 208 may be a
rectangular plate to facilitate for symmetrical design of the
support frame 20, but is not limited thereto. A bottom end of the
first buffer plate 209 and a bottom end of the second buffer plate
210 are respectively connected to the opposite ends of the bottom
plate 208, and a top end of the first buffer plate 209 and a top
end of the second buffer plate 210 extend in a direction closing to
each other. The top end of the first buffer plate 209 and the
bottom plate 208 are separately disposed, and the top end of the
second buffer plate 210 and the bottom plate 208 are separately
disposed, that is, a buffer space is formed between the first
buffer plate 209 and the bottom plate 208, and a buffer space is
formed between the second buffer plate 210 and the bottom plate
208, in this way, elasticity of the base of the support frame 20
can be increased.
[0053] The top end of the first buffer plate 209 and the top end of
the second buffer plate 210 are connected to the bottom end of the
first support plate 201 and the bottom end of the second support
plate 202, respectively. An angle between the first buffer plate
209 and the bottom plate 208 is smaller than an angle between the
first support plate 201 and the bottom plate 208. An angle between
the second buffer plate 210 and the bottom plate 208 may be smaller
than an angle between the second support plate 202 and the bottom
plate 208, so that support stability of the support frame 20 can be
ensured while ensuring elasticity of the support frame 20.
[0054] It should be noted that the first support portion and the
second support portion may be symmetrically disposed with respect
to a center line a of the bottom plate 208. The first buffer plate
209 and the second buffer plate 210 may be symmetrically disposed
with respect to the center line a of the bottom plate 208. It
should be understood that, as the specifications of the first
display structure 30 and the second display structure 31 may be
completely the same, the first display structure 30 and the second
display structure 31 may also be symmetrically disposed with
respect to the center line a of the bottom plate 208 when the first
display structure 30 and the second display structure 31 are
respectively mounted on the first support portion and the second
support, so as to ensure that the entire electronic sign is a
symmetrical structure, and the center of gravity of the entire
electronic sign is located at the center line a of the bottom plate
208, thereby ensuring the structural stability of the entire
electronic sign and avoiding the situation that the electronic sign
is prone to fall off.
[0055] It should also be noted that the support frame 20 of this
embodiment may be an integrated structure to ensure the structural
stability of the entire support frame 20. In other words, the base,
the first support portion and the second support portion may be
integrally formed.
[0056] In an embodiment, as shown in FIG. 2, after the first power
supply portion 302 is engaged with the first engaging portion 203
and the second power supply portion 312 is engaged with the second
engaging portion 204, the top end of the first display screen 301
is in contact with the top end of the second display screen 311, so
that as compared with the solution in that the top end of the first
display screen 503 and the top end of the second display screen 504
are separately disposed (as shown in FIG. 5 and FIG. 6), the
situation that the first display screen 301 and the second display
screen 311 are prone to shake during use can be avoided, and thus
the situation that the first display structure 30 and the second
display structure 31 are easily detached from the support frame 20
can be avoided, and the structural stability of the entire
electronic sign can be ensured.
[0057] Specifically, as shown in FIG. 2, when the top end of the
first display screen 301 is in contact with the top end of the
second display screen 311, the first support plate 201 and the
second support plate 202 are elastically deformed in a direction
away from each other. At this time, the first support plate 201 and
the second support plate 202 each generate a return force. Under an
action of the return force, the top end of the first display screen
301 and the top end of the second display screen 311 can be in
close contact with each other to ensure structural stability of the
electronic sign.
[0058] It should be understood that, in order to make the first
support plate 201 and the second support plate 202 elastically
deform in a direction away from each other when the top end of the
first display screen 301 is in contact with the top end of the
second display screen 311, when a single display structure is
assembled on the support frame 20, for example, when the first
display structure 30 is assembled on the first support portion, as
shown in FIG. 3, the top end of the first display screen 301 in the
first display structure 30 should be beyond the center line a of
the bottom plate 208, so that when the second display structure 31
is assembled on the second support portion, firstly, a pulling
force is applied to the second support plate 202 to pull the second
support plate 202 away from the first support plate 201, that is,
the second support plate 202 is elastically deformed in a direction
away from the first support plate 201 to prevent interference
between the second display screen 311 and the first display screen
301 during engagement between the second power supply portion 312
and the second engaging portion 204, thereby facilitate assembling
the second display structure 31 to the second support portion.
After the second display structure 31 is assembled on the second
support portion, the pulling force applied to the first support
plate 201 is removed. The first support plate 201 moves in a
direction closing to the second support plate 202 under the action
of its own return force. During the return process of the first
support plate 201, the top end of the second display screen 311 can
apply a pushing force to the top end of the first display screen
301 to push the top end of the first display screen 301 to move
away from the second support plate 202, so as to drive the top end
of the first support plate 201 to move away from the second support
plate 202, that is, elastic deformation occurs in a direction away
from the second support plate 202. At this time, the first support
plate 201 will generate a return force, and the top end of the
second support plate 202 is not reset to the initial position.
Therefore, the second support plate 202 still has a part of the
return force.
[0059] When the return force of the first support plate 201 is the
same as that of the second support plate 202, the first display
screen 301 and the second display screen 311 reach a balanced
state; and the top end of the first display screen 301 and the top
end of the second display screen 311 can be brought into close
contact under the return force of the first support plate 201 and
the second support plate 202. As shown in FIG. 2, the center line a
of the bottom plate 208 may pass through the position where the top
end of the first display screen 301 is in contact with the top end
of the second display screen 311, to ensure the symmetry of the
electronic sign, ensure the stability of the electronic sign, and
avoid the situation that the electronic sign is prone to fall
off.
[0060] In addition, the top end of the first display screen 301 and
the top end of the second display screen 311 may be brought into
close contact under the return force of the first support plate 201
and the second support plate 202, as shown in FIG. 2, the first
power supply portion 302, the second power supply portion 312 may
also be in close contact with the frosted surface 207 on the first
support plate 201 and the frosted surface 207 on the second support
plate 202, respectively, so as to achieve mutual limitation, and
thus improve the assembly stability of the first display structure
30 and the second display structure 31. Based on this solution, the
interferences between the first power supply portion 302 and the
first engaging portion 203, and between the second power supply
portion 312 and the second engaging portion 204 in this embodiment
are not required, that is, the first power supply portion 302 is in
clearance fit with the first engaging portion 20; the second power
supply portion 312 is in clearance fit with the second engaging
portion 204, so that the first power supply portion 302 can be
easily inserted into the engaging space 205 of the first engaging
portion 203, and the second power supply portion 312 can be easily
inserted into the engaging space 205 of the second engaging portion
204.
[0061] Optionally, as shown in FIG. 2, the top end of the first
display screen 301 may be in surface contact with the top end of
the second display screen 311 to increase a contacting area between
the first display screen 301 and the second display screen 311.
Further, as shown in FIG. 3 and FIG. 4, each of the top end of the
first display screen 301 and the top end of the second display
screen 311 is provided with a first anti-slip film 32. The surface
contact between the first anti-slip film 32 of the first display
screen 301 and the first anti-slip film 32 of the second display
screen 311 can increase the friction force between the first
display screen 301 and the second display screen 311, and ensure
the stable contact between the first display screen 301 and the
second display screen 311.
[0062] Each of a surface of the first power supply portion 302 away
from the first display screen 301 and a surface of the second power
supply portion 312 away from the second display screen 311 is
provided with a second anti-slip film 33. The second anti-slip film
33 of the first power supply portion 302 may be attached to the
first support plate 201, and specifically to the frosted surface
207 of the first support plate 201, to increase the friction force
between the first power supply portion 302 and the first support
plate 201, thereby ensuring that the first display structure 30 is
stably mounted on the first support portion. The second anti-slip
film 33 of the second power supply portion 312 may be attached to
the second support plate 202, and specifically to the frosted
surface 207 of the second support plate 202, to increase the
friction between the second power supply portion 312 and the second
support plate 202, thereby ensuring that the second display
structure 31 is stably mounted on the second support portion.
[0063] It should be noted that the first anti-slip film 32 and the
second anti-slip film 33 may be made of an ultra-high molecular
polyethylene material, so that the first anti-slip film 32 and the
second anti-slip film 33 have advantages such as abrasion
resistance, impact resistance, corrosion resistance,
self-lubrication, impact absorption, and the like.
[0064] In addition, it should be noted that, in order to ensure the
appearance and texture of the first display structure 30 and the
second display structure 31, grooves may be provided at a part of
the casing facing to the top end of the display screen and at a
part of the casing facing to the power supply portion. The first
anti-slip film 32 and the second anti-slip film 33 may be
respectively located in the grooves, and a thickness of the first
anti-slip film 32 or the second anti-slip film 33 may be equal to
or slightly larger than a depth of the groove thereof.
[0065] Optionally, as shown in FIG. 2, when the first display
structure 30 and the second display structure 31 are respectively
mounted on the first support structure and the second support
structure, and the top end of the first display screen 301 is in
contact with the top end of the second display screen 311, the
first support plate 201 and the first display screen 301 are
parallel to each other, and the second support plate 202 and the
second display screen 311 are parallel to each other, to ensure the
structural stability of the entire electronic sign.
[0066] In addition, in the present disclosure, the top end of the
first support plate and the top end of the second support plate in
the support frame are disposed separately, to increase the
deformation capacity of the first support plate and the second
support plate in the support frame, and facilitate engaging the two
display structures respectively to the first engaging portion and
the second engaging portion, so as to assemble an electronic
sign.
[0067] In other embodiments,
