DESCRIPTION OF EMBODIMENTS

[0029] The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention.

[0030] Referring to FIG. 1 to FIG. 4, FIG. 1 to FIG. 4 show a wearable device according to a first embodiment of the present invention. The wearable device may be a device that can be worn on a wrist, an ankle, or another part, such as a watch, a smartwatch, a smart band, or a smart wristband. In this embodiment, the wearable device is a watch. The wearable device includes a main body 100 and a wristband 200. The main body 100 includes a main case 1 and a bottom cover 2 that are fixedly connected to each other. The main body 100 may be a body of the watch. The main case 1 is an upper case of the body. The bottom cover 2 is a bottom cover 2 of the body.

[0031] As shown in FIG. 1 and FIG. 2, a connection member 3 is disposed on the main case 1, and is configured to connect to a spring bar 9 on the wristband. 200. By means of cooperation between the connection member 3 and the spring bar 9, the main body 100 can be connected to or detached from the wristband 200. The wristband 200 usually includes two parts. The two parts are respectively connected to two ends of the main body 100. Correspondingly, two connection members 3 are disposed on the main case 1, and a spring bar 9 is disposed on each of the two parts of the wristband 200.

[0032] Each connection member 3 has two connection lugs 31, and a connection cavity is formed between the two connection lugs 31. The spring bars 9 are disposed on the wristband 200, and the spring bar 9 can be connected to the connection cavity. The spring bar 9 may be the same as a spring bar in the prior art. A telescopic head 91 is disposed at each end of the spring bar 9. The two telescopic heads 91 are respectively inserted to the two connection lugs 31. By means of stretching and contraction of the telescopic head 91, the spring bar 9 can be connected to or detached from the connection lugs 31. Because the spring bar in the prior art can be used as the spring bar 9, the connection member 3 can be correspondingly connected to a wristband in the prior art directly without needing to perform special processing on a structure of the wristband, thereby making it convenient for a user to change the wristband.

[0033] An accommodating hole 30 is provided on each connection lug 31. One end of the accommodating hole 30 has an opening, and the other end of the accommodating hole 30 is provided with a connection portion 32. The connection portion 32 is closer to the other connection lug 31 than the opening of the accommodating hole 30. The connection portion 32 is provided with a through hole 320 in communication with the accommodating hole 30. A button 33 is disposed on each connection lug 31. The button 33 is slidably disposed in the accommodating hole 30. By means of the accommodating hole 30, the button 33 can be conveniently disposed, and sliding of the button 33 is facilitated. The connection portion 32 limits a maximum distance by which the button 33 can slide into the accommodating hole 30. By means of the opening of the accommodating hole 30, the button 33 can be disposed in the accommodating hole 30 through the opening. This facilitates assembly. The through hole 320 may correspondingly match the telescopic head 91 of the spring bar 9, to facilitate insertion of the telescopic head 91.

[0034] As shown in FIG. 3 and FIG. 4, a locating groove 310 is provided on a surface of the connection lug 31 facing the bottom cover 2. The locating groove 310 is in communication with the accommodating hole 30. A limiting groove 330 is provided at a position that is on the button 33 and that is corresponding to the locating groove 310. A limiting portion 22 is disposed on the bottom cover 2. The limiting portion 22 is located in the locating groove 310 and extends into the limiting groove 330. The limiting portion 22 can prevent the button 33 from moving out of the opening of the accommodating hole 30. Because the locating groove 310 is provided on the surface of the connection lug 31 facing the bottom cover 2, the limiting portion 22 may enter the locating groove 310 and the limiting groove 330 in sequence when the bottom cover 2 is connected to the main case 1 during assembly, and after assembly, the limiting portion 22 is located in the limiting groove 330, and therefore can limit a sliding range of the button 33, thereby preventing the button 33 from moving out of the accommodating hole 30.

[0035] When the main body 100 is connected to the wristband 200, the telescopic head 91 is in a stretching state and is inserted into the through hole 320, and the button 33 moves toward the opening of the accommodating hole 30 by the maximum distance. In this case, the button 33 protrudes out of the opening of the accommodating hole 30, making it convenient for the user to press the button 33 inward. When the wristband 200 needs to be detached from the main body 100, the user may press the buttons 33 on the two connection lugs 31 at the same time. When pressed, the two buttons 33 move toward each other, and move toward inside of the accommodating hole 30. When moving toward the inside of the accommodating hole 30, the buttons 33 press against the telescopic heads 91, so that the telescopic heads 91 contract. The telescopic heads 91 can move out of the through holes 320. In this way, the wristband 200 is detached from the main body 100, providing convenient and rapid use.

[0036] According to the wearable device provided in the present invention, during assembly, the button 33 may be first disposed in the accommodating hole 30 through the opening of the accommodating hole 30, the limiting groove 330 of the button 33 is aligned with the locating groove 310, and the bottom cover 2 is assembled onto the main case 1. In this way, the limiting portion 22 can be inserted into the locating groove 310 and the limiting groove 330, so that the button 33 is limited in the accommodating hole 30. Therefore, the wearable device has a simple structure, and is convenient and rapid to assemble. When the two buttons 33 are pressed at the same time, the two telescopic heads 91 of the spring bar 9 are caused to contract, so that the spring bar 9 can be removed from the two connection lugs 31, thereby detaching the wristband 200 from the main body 100. Therefore, it is convenient to use.

[0037] Preferably, the accommodating hole 30 is a circular hole, and the button 33 is correspondingly cylinder-shaped. Certainly, in another implementation, the accommodating hole 30 may alternatively be a rectangular hole, and the button 33 is correspondingly cuboid-shaped. Alternatively, the accommodating hole 30 is a triangular hole, and the button 33 is correspondingly triangular prism-shaped.

[0038] In this embodiment, an elastic member 34 is disposed in the accommodating hole 30, the elastic member 34 is connected to the button 33, and the elastic member 34 is capable of providing, to the button 33, an elastic force toward the opening of the accommodating hole 30. By means of the elastic member 34, the button 33 can automatically return to a state before being pressed. Therefore, it is convenient to use.

[0039] Preferably, the elastic member 34 may be a compression spring, and two ends of the compression spring respectively press against the button 33 and the connection portion 32. When the button 33 moves toward .sup.-the connection portion 32, the elastic member 34 is compressed and generates a deformation force, so as to provide, to the button 33, the elastic force toward the opening of the accommodating hole 30, so that the button 33 can automatically return to an original state after being pressed.

[0040] Further, a blind hole 334 is provided on an end face of the button 33 close to the connection portion 32. The elastic member 34 is inserted into the blind hole 334. By means of the blind hole 334, positioning between the elastic member 34 and the button 33 can be achieved, so as to prevent the elastic member 34 and the button 33 from moving relative to each other during compression to affect the elastic force on the button 33. The blind hole 334 and the compression spring 34 are both located on a principal axis of the button 33, so that the elastic member 34 can exert a relatively even force on the button 33.

[0041] A protrusion 331 is disposed on the end face of the button 33 close to the connection portion 32. When the button 33 moves toward the accommodating hole 30, the protrusion 331 moves into the through hole 320, and presses against the telescopic head 91. When the button 33 is pressed, the protrusion 331 may move into the through hole 320. A force is exerted on the telescopic head 91 of the spring bar 9 by means of the protrusion 331, to cause the telescopic head 91 to contract, so that the telescopic head 91 moves out of the through hole 320 completely, making it convenient to remove the spring bar 9 from the two connection lugs 31. The protrusion 331 is located at an eccentric position on the button 33, so that the protrusion 331 and the elastic member 34 are staggered relative to each other, to facilitate connection during assembly.

[0042] In this embodiment, a guiding bevel 35 is disposed on each connection lug 31. The guiding bevel 35 has a first end and a second end that are opposite to each other. Between the guiding bevels 35 of the two connection lugs 31, a spacing between the two first ends is greater than a spacing between the two second ends. The first end is located at an edge of the connection lug 31, and the second end extends to the through hole 320. When the spring bar 9 is connected to the two connection lugs 31, the telescopic heads 91 at the two ends of the spring bar 9 respectively press against the first ends of the two guiding bevels 35. When the spring bar 9 is moved toward the through holes 320, the two telescopic heads 91 can gradually move along the guiding bevels 35 and gradually contract, making it convenient to insert the two telescopic heads 91 into the through holes 320 of the connection lugs 31.

[0043] More specifically, a guiding groove 36 is provided on each connection lug 31. A groove bottom surface of the guiding groove 36 forms the guiding bevel 35. By means of the guiding groove 36, the telescopic lug can be accurately moved into the through hole 320, providing convenient assembly. Herein, in another implementation, the guiding groove 36 may not be provided. An outer surface of the connection lug 31 may be used to directly form the guiding bevel 35.

[0044] Because there are two connection members 3, there are four connection lugs 31 correspondingly, and there are four corresponding limiting portions 22, to respectively limit the four buttons 33. In this embodiment, the limiting portions 22 and the bottom cover are integrally formed. The four limiting portions 22 and the bottom cover form one component. When the bottom cover is mounted on the main case 1 by using a screw, the limiting portions 22 are positioned in the connection lugs 31 and cannot move, providing convenient assembly. When the bottom cover is mounted, mounting of the limiting portions 22 is also implemented, so as to limit the buttons 33. This facilitates mounting and removal and can reduce a quantity of parts, facilitating processing and production. Herein, in another implementation, the limiting portions 22 and the bottom cover 2 may form a separable structure. The four limiting portions 22 are independent components, and may be mounted respectively on the four connection lugs 31. An edge of the bottom cover 2 presses against the locating grooves 310, to fasten the limiting portions 22 to the connection lugs 31. During assembly, the limiting portions 22 may be first disposed in the locating grooves 310, followed by mounting of the bottom cover 2. In this way, the assembly is completed, and the limiting portions 22 do not need to be separately fastened by using a fastener such as a screw, providing convenient assembly. In the foregoing implementation, the limiting portion 22 and the bottom cover 2 may be made of a same material, for example, a metal. In still another implementation, a seal ring is disposed on the bottom cover 2. The seal ring is located between the bottom cover 2 and the main case 1, and is used for sealing between the bottom cover 2 and the main case 1. The limiting portions 22 and the seal ring form a one-piece structure. After the seal ring is mounted on the bottom cover 2, the limiting portions 22 can also be mounted on the bottom cover 2. After the bottom cover 2 is fastened to the main case 1 by using a screw, the limiting portion 22 can also be fastened to connection lugs 31. The limiting portion 22 and the seal ring may be made of a rubber material, so that sealing can be achieved at the locating groove 310.

[0045] As shown in FIG. 5, in a second embodiment of a wearable device provided in the present invention, structures of components such as a main case 1a, a bottom cover 2a, and buttons 32a are generally the same as those in the first embodiment. Herein, only differences are described in detail, and other parts are not described herein again.

[0046] In this embodiment, as shown in FIG. 5, the elastic member is a rotary spring 34a. The rotary spring 34a is mounted on a connection lug 31a. One supporting arm of the rotary spring is connected to the connection lug 31a, and the other supporting arm 341a of the rotary spring is connected to the button 33a, During sliding, the button 33a can drive the other supporting arm 341a of the rotary spring to move, so that the rotary spring 34a generates an elastic force, to cause the button 33a to return to a position before being pressed. The other supporting arm 341a of the rotary spring 34a may extend into the limiting groove 330a. The rotary spring is connected to the button 33a by means of the limiting groove 330a, providing convenient assembly.

[0047] More specifically, a mounting groove 39a is provided on the connection lug 31a. An opening of the mounting groove 39a faces the bottom cover 2a. A middle ring-shaped part 342a of the rotary spring 34a is assembled in the mounting groove 39a through the opening of the mounting groove 39a. A limiting portion 22a blocks the opening of the mounting groove 39a to limit the rotary spring 34a in the mounting groove 39a. This facilitates assembly of the rotary spring 34a and the connection lug 31a. The rotary spring 34a can also be positioned when the bottom cover 2a is mounted, providing convenient and rapid assembly. Further, a mounting column 391a is further disposed in the mounting groove 39a. The middle ring-shaped part 342a of the rotary spring 34a is sleeved on the mounting column 391a, to further facilitate positioning and mounting of the rotary spring 34a.

[0048] Herein, in another embodiment, the elastic member may alternatively be an elastic component in another structural form, such as an elastic plate or an elastic silicone pad, provided that the elastic component is capable of providing a force to the button to cause the button to move toward the opening of the accommodating hole.

[0049] In the foregoing embodiment, when the button moves toward the inside of the accommodating hole by the maximum distance, the telescopic head of the spring bar can completely move out of the through hole. Therefore, the spring bar can be removed from the two connection lugs without needing to further exert a force on the wristband. Herein, in another implementation, as shown in FIG. 6, in a wearable device provided in a third embodiment of the present invention, after a button 33b moves toward inside of an accommodating hole 30b by a maximum distance, an end of a telescopic head 91h is located in a through hole 320b, and the telescopic head 91b does not completely move out of the through hole 320. A hole wall that is in the through hole 320b and that is corresponding to the end of the telescopic head 91b is a tapered surface, and a diameter of an end of the tapered surface close to a spring bar 9 is relatively large. By means of the tapered surface, the telescopic head 91b can be caused to contract by pulling the spring bar outward, making it convenient to remove the spring bar. Further, when the button moves toward the inside of the accommodating hole by the maximum distance, the end of the telescopic head 91b that is in the through hole 320b is convex arc-shaped. During detaching, the button 33b is pressed, and after a three is exerted on the spring bar, the telescopic head 91b can contract and completely move out of the through hole 320b by means of the convex arc-shaped end, so that the spring bar is removed. Further, after the button 33b moves toward the inside of the accommodating hole 30b by the maximum distance, because the telescopic head 91b does not completely move out of the through hole 320b after the button 33b is completely pressed, the spring bar does not fall off automatically, thereby preventing the wristband from suddenly falling off upon pressing of the button 33b.

[0050] The foregoing implementations are not intended to limit the protection scope of the technical solutions. Any modification, equivalent replacement, and improvement made without departing from the spirit and principle of the foregoing implementations shall fall within the protection scope of the technical solutions.
