DETAILED DESCRIPTION
[0008] It will be appreciated that for simplicity and clarity of
illustration, where appropriate, reference numerals have been
repeated among the different figures to indicate corresponding or
analogous elements. Additionally, numerous specific details are set
forth in order to provide a thorough understanding of the
embodiments described herein. However, it will be understood by
those of ordinary skill in the art that the embodiments described
herein can be practiced without these specific details. In other
instances, methods, procedures and components have not been
described in detail so as not to obscure the related relevant
feature being described. The drawings are not necessarily to scale
and the proportions of certain parts may be exaggerated to better
illustrate details and features. The description is not to be
considered as limiting the scope of the embodiments described
herein.
[0009] Several definitions that apply throughout this disclosure
will now be presented.
[0010] The term "coupled" is defined as connected, whether directly
or indirectly through intervening components, and is not
necessarily limited to physical connections. The connection can be
such that the objects are permanently connected or releasably
connected. The term "substantially" is defined to be essentially
conforming to the particular dimension, shape, or other word that
"substantially" modifies, such that the component need not be
exact. For example, "substantially cylindrical" means that the
object resembles a cylinder, but can have one or more deviations
from a true cylinder. The term "comprising" means "including, but
not necessarily limited to"; it specifically indicates open-ended
inclusion or membership in a so-described combination, group,
series and the like.
[0011] FIG. 1 shows an embodiment of a wearable device 200 that
includes a connection structure 100.
[0012] Referring to FIG. 2, the connection structure 100 includes a
main body 10, a fastening assembly 20, a pressing member 30, and a
movable piece 40. The main body 10 includes a fastening groove 11.
The fastening assembly 20 is rotationally mounted in the fastening
groove 11 of the main body 10. The fastening assembly 20 includes a
first end portion 21 and a second end portion 22. The first end
portion 21 and the second end portion 22 are respectively opposite
ends of the fastening assembly 20. A latching portion 23 protruding
from the first end portion 21. The pressing member 30 is located on
the second end portion 22. One end of the movable piece 40 is
rotationally coupled to the second end portion 22 on a side of the
fastening assembly 20 facing away from the latching portion 23. The
movable piece 40 extends beyond the second end portion 22.
[0013] The wearable device 200 further includes a snap portion 210,
a device main body 220, and a connecting member 230 configured to
snap-fit with the connection structure 100. The snap portion 210
has a substantially T-shaped cross-section and protrudes from one
side of the device main body 220. The device main body 220 is
snap-fitted with the latching portion 23 of the connection
structure 100 by the snap portion 210 on one end of the main body
10. The connecting member 230 is fixedly coupled to a second end of
the main body 10 away from the device main body 220. In one
embodiment, the connecting member 230 is a connecting cord which
can be worn on the neck of a user.
[0014] In other embodiments, the snap portion 210 can be a recess,
and the latching portion 23 of the fastening assembly 20 can be
engaged in the snap portion 210.
[0015] The fastening assembly 20 is configured to rotate in the
fastening groove 11, so that the first end portion 21 of the
fastening assembly 20 rotates away from the snap portion 210 to
disengage the latching portion 23 from the snap portion 210.
[0016] The main body 10 is substantially cylindrical. The fastening
groove 11 has a substantially rectangular cross-section and extends
from one end of the main body 10 to another end of the main body 10
along an axis of the main body 10. One end of the fastening groove
11 penetrates an end surface of the main body 10. A blocking
portion 12 is located in the fastening groove 11. The blocking
portion 12 is configured to limit movement of the latching portion
23 in the fastening groove 11.
[0017] In other embodiments, the fastening groove 11 may penetrate
both ends of the main body 10 along the axis of the main body
10.
[0018] In other embodiments, the cross-sectional shape of the
fastening groove 11 may be a triangle, a pentagon, a hexagon, or
other shape, as long as the cross-sectional shape of the snap
portion 210 is the same as the cross-sectional shape of the
fastening groove 11 and can be fastened in the fastening groove
11.
[0019] The fastening assembly 20 is substantially elongated. The
latching portion 23 can be snap-fitted with the snap portion 210 to
fix the device main body 220 in the fastening groove 11. The
fastening assembly 20 includes a rotating portion 24. The rotating
portion 24 is substantially lug-shaped. The number of the rotating
portions 24 is two, and the two rotating portions 24 are arranged
in parallel and spaced apart. The two rotating portions 24 are
rotationally coupled to the main body 10 through a rotary shaft 25
inside the fastening groove 11. The first end portion 21 and the
second end portion 22 are respectively located on opposite sides of
the rotating portion 24.
[0020] The fastening assembly 20 further includes a limiting
portion 26. The limiting portion 26 is substantially
cylindrical-shaped. The limiting portion 26 extends from the second
end portion 22 and is configured to prevent the pressing member 30
from rotating.
[0021] In other embodiments, the limiting portion 26 can be a
groove-shaped structure arranged on the second end portion 22, and
one end of the pressing member 30 is locked in the groove structure
to prevent the pressing member 30 from rotating.
[0022] The pressing member 30 is made of an elastic material. One
end of the pressing member 30 abuts against the second end portion
22 of the fastening assembly 20, and a second end abuts against the
main body 10 in the fastening groove 11. In one embodiment, the
pressing member 30 is a spring and is sleeved on the limiting
portion 26.
[0023] Referring to FIGS. 1-3, one end of the movable piece 40 is
rotationally coupled to a side of the fastening assembly 20 facing
away from the latching portion 23 by a pin 41, and a second end of
the movable piece 40 is configured to overlap with an end of the
main body 10 adjacent to the pressing member 30.
[0024] Referring to FIG. 4, to fasten the device main body 220 to
the main body 10, the movable piece 40 is first rotated to position
both ends of the movable piece 40 above the fastening assembly 20,
the second end portion 22 of the fastening assembly 20 is pressed
to fasten the snap portion 210 of the main body 220 with the
latching portion 23 of the connection structure 100, and then the
movable piece 40 is rotated to overlap the second end of the
movable piece 40 with the main body 10. The second end of the
movable piece 40 overlapped with the main body 10 prevents
inadvertently pressing the second end portion 22 of the fastener 20
during use to disengage the device main body 220 from the
connection structure 100. The connecting member 230 is coupled to
one end of the main body 10 away from the latching portion 23. The
snap portion 210 engaged between the latching portion 23 and the
blocking portion 12 restrains movement of the snap portion 210.
[0025] Compared with the related art, the first end portion 21 of
the fastening assembly 20 can be rotated away from the snap portion
210 by pressing the second end portion 22 of the fastening assembly
20 to disengage the latching portion 23 from the snap portion 210.
Thus, the latching portion 23 is easily disengaged from the snap
portion 210, and a snap-fit coupling between the snap portion 210
and the latching portion 23 prevents the wearable device 200 from
rotating during use.
[0026] The embodiments shown and described above are only examples.
Even though numerous characteristics and advantages of the present
technology have been set forth in the foregoing description,
together with details of the structure and function of the present
disclosure, the disclosure is illustrative only, and changes may be
made in the detail, including in matters of shape, size and
arrangement of the parts within the principles of the present
disclosure up to, and including, the full extent established by the
broad general meaning of the terms used in the claims.
