[0035] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] As a portable display device that can be worn on the arm, a watch is mainly composed of a watch body and a watch strap. In daily use, people often combine the watch body with different styles of watch straps to make the watch present different styles. In order to meet people's needs for replacing watch straps, watch straps are usually designed to be detachable. However, in the actual research and development and production process, researchers found that traditional watches mainly use spring ears to connect the watch strap to the watch body. The spring ear is a connecting component used to connect the watch strap and the watch body. It is mainly composed of a sleeve, a spring inserted in the sleeve, and a spring ear head set at both ends of the spring. When removing and installing the watch strap, the user needs to use a special tool to hold the spring ear head, which requires the user to operate tiny parts, which makes the disassembly and assembly process of the watch strap cumbersome and increases the difficulty of disassembly and assembly of the watch strap.

[0037] The present invention provides a wearable device and a wristwatch, aiming to solve the technical problems that the disassembly and assembly process of a watch strap is complicated and the disassembly and assembly is difficult.

[0038] See also Figures 1 to 3 In one embodiment of the present invention, the wearable device includes a body 100, a fixing block 200, a fixing belt 300 and a locking member 400. The fixing block 200 is arranged on the body 100 and is surrounded with the body 100 to form a slot 210. The fixing belt 300 is provided with an insert block 310, and the insert block 310 is inserted into the slot 210. The locking member 400 is slidably arranged on the fixing belt 300, and the locking member 400 has a locking position and an unlocking position; when the locking member 400 is in the locking position, the locking member 400 abuts against a side of the fixing block 200 away from the opening of the slot 210; when the locking member 400 is in the unlocking position, the locking member 400 is separated from the fixing block 200.

[0039] The technical solution of the present invention is to insert the insert block 310 into the slot 210, lock the fixing belt 300 in the length direction and width direction of the fixing belt 300, and slide the locking member 400 into the fixing belt 300 to lock the position of the fixing belt 300 in the thickness direction of the fixing belt 300 or release the position lock of the fixing belt 300, so that when the user disassembles the fixing belt 300, he only needs to slide the locking member 400, which can simplify the disassembly and assembly process of the fixing belt 300 and reduce the difficulty of disassembly and assembly of the fixing belt 300; accordingly, when the wearable device is a watch, the disassembly and assembly process of the watch strap can be simplified and the difficulty of disassembly and assembly can be reduced. In this embodiment, the fixing belt 300 is used to fix the body 100 to the part to be worn, such as the wrist, the head, etc. By inserting the insert block 310 of the fixing belt 300 into the slot 210, the position of the fixing belt 300 can be locked in the length direction and width direction of the fixing belt 300, and at this time, the fixing belt 300 cannot be separated from the body 100 along its length direction or width direction. The locking member 400 is slidably disposed on the fixing belt 300 and can be switched between a locked position and an unlocked position; when the locking member 400 is switched to the locked position, the locking member 400 abuts against a side of the opening of the fixing block 200 away from the slot 210, thereby locking the position of the fixing belt 300 in the thickness direction of the fixing belt 300; and when the locking member 400 is switched to the unlocked position, the locking member 400 is misaligned and separated from the fixing block 200, at which time the position lock of the fixing belt 300 in its thickness direction is released, and the fixing belt 300 can move along its thickness direction in a direction away from the fixing block 200. Specifically, when installing the fixing belt 300, the user first inserts the plug block 310 into the slot 210, and then switches the locking piece 400 to the locking position, so that the position of the fixing belt 300 can be locked in the length direction, width direction and thickness direction of the fixing belt 300, and the installation of the fixing belt 300 is completed; when removing the fixing belt 300, the user switches the locking piece 400 to the unlocking position. At this time, the position lock of the fixing belt 300 in its thickness direction is released, and the user drives the fixing belt 300 to move along its thickness direction in the direction away from the fixing block 200, so that the fixing belt 300 can be removed, and the removal of the fixing belt 300 is completed.

[0040] In this embodiment, the slot 210 includes a bottom wall 211, two first side walls 212 arranged opposite to each other along the length direction of the fixing belt 300, and two second side walls 213 arranged opposite to each other along the width direction of the fixing belt 300; the two sides of the insert block 310 along the length direction of the fixing belt 300 are respectively abutted against the two first side walls 212 to lock the position of the fixing belt 300 in the length direction of the fixing belt 300; the two sides of the insert block 310 along the width direction of the fixing belt 300 are respectively abutted against the two second side walls 213 to lock the position of the fixing belt 300 in the width direction of the fixing belt 300; the side of the insert block 310 facing away from the fixing belt 300 is abutted against the bottom wall 211, and the locking piece 400 can abut against the side of the fixing block 200 facing away from the opening of the slot 210 to lock the position of the fixing belt 300 in the thickness direction of the fixing belt 300.

[0041] See also Figure 2 , Figure 5 and Figure 6In one embodiment of the present invention, the fixing belt 300 is provided with an open cavity 320, the plug block 310 is provided in the open cavity 320, and the locking member 400 includes a sliding portion 410 and a locking portion 420 which are staggered. The sliding portion 410 is slidably provided in the open cavity 320 and can slide in a direction close to or away from the plug block 310, and the locking portion 420 is provided in the sliding portion 410 and exposed to the fixing belt 300. The sliding portion 410 can be a slider, and the locking portion 420 can be an extension block provided on the slider. Specifically, the open cavity 320 is opened on the fixing belt 300, the plug block 310 is provided in the open cavity 320, and the sliding portion 410 is slidably provided in the open cavity 320 and can slide in a direction close to or away from the plug block 310, so that the structure of the wearable device can be optimized and the structure of the wearable device can be made more compact. The locking portion 420 and the sliding portion 410 are offset from each other in order to ensure that the locking member 400 can abut against the side of the opening of the fixed block 200 away from the slot 210. The reason is that: when the plug block 310 is set in the open cavity 320, when the plug block 310 is inserted into the slot 210 and the sliding portion 410 is slidably set in the open cavity 320 so that it can slide toward or away from the plug block 310, the sliding portion 410 is bound to be unable to abut against the side of the opening of the fixed block 200 away from the slot 210. By offsetting the locking portion 420 and the sliding portion 410, the locking member 400 can abut against the side of the opening of the fixed block 200 away from the slot 210 through the locking portion 420, thereby locking the position of the fixed belt 300 in the thickness direction of the fixed belt 300. When the locking member 400 is in the locked position, the locking portion 420 is arranged corresponding to the fixed block 200, and the locking portion 420 abuts against the side of the fixed block 200 away from the opening of the slot 210; when the locking member 400 is in the unlocked position, the locking portion 420 is arranged offset from the fixed block 200, that is, the locking portion 420 is separated from the fixed block 200. In a specific embodiment, the open cavity 320 extends along the length direction of the fixed belt 300, and the sliding portion 410 is slidably arranged in the open cavity 320 along the length direction of the fixed belt 300. In another embodiment of the present invention, the locking member 400 can also be a locking plate, a slide groove is provided on the fixed belt 300, the locking plate is slidably arranged in the slide groove, and the locking plate can switch between the locked position and the unlocked position. When the locking plate is in the locked position, the side of the locking plate close to the body 100 abuts against the side of the fixing block 200 facing away from the opening of the slot 210; when the locking plate is in the unlocked position, the locking plate and the fixing block 200 are offset, that is, the locking plate and the fixing block 200 are separated.

[0042] See also Figures 5 to 7In one embodiment of the present invention, the locking member 400 further includes a plug-in member 430, the sliding portion 410 is provided with a receiving cavity 411, a strip groove 321 is provided on the side wall of the open cavity 320, the plug-in member 430 is provided in the receiving cavity 411, and the plug-in member 430 extends out of the sliding portion 410 and is slidably provided in the strip groove 321. In this embodiment, the portion of the plug-in member 430 extending out of the sliding portion 410 is slidably provided in the strip groove 321, which can provide guidance for the sliding of the sliding portion 410 in the open cavity 320 and improve the stability of the sliding portion 410 when sliding in the open cavity 320. In a specific embodiment, the strip groove 321 is in the shape of a long strip, and the strip groove 321 extends along the length direction of the fixing belt 300. Specifically, the plug-in member 430 may include the two sliding rods 431 described below, or may include two plug-in rods. In one embodiment of the present invention, the connector 430 includes two plug-in rods, which are rotatably arranged on both sides of the sliding portion 410 through two rotating shafts; each plug-in rod can be rotated into the accommodating cavity of the sliding portion 410 and can be rotated to be perpendicular to the side of the sliding portion 410. In order to ensure that the plug-in rod can be rotated to be perpendicular to the side of the sliding portion 410, a torsion spring can be arranged on the rotating shaft to drive the plug-in rod to rotate to a position perpendicular to the side of the sliding portion 410.

[0043] In one embodiment of the present invention, the plug-in component 430 includes two slide bars 431. The two opposite side walls of the open cavity 320 are provided with strip grooves 321. The two slide bars 431 extend out of the two sides of the sliding part 410 and are slidably disposed in the corresponding strip grooves 321. In this embodiment, the portion of each slide bar 431 extending out of the sliding part 410 is slidably disposed in the corresponding strip groove 321, which can improve the stability of the sliding part 410 when sliding in the open cavity 320. In addition, an elastic member 432 is disposed between the two slide bars 431; the elastic member 432 drives the two slide bars 431 to move in a direction away from each other. Specifically, the elastic member 432 can provide a thrust to drive the two slide bars 431 to move away from each other, so that the ends of the two slide bars 431 always extend out of the slide part 410, so as to ensure that the portions of the two slide bars 431 extending out of the slide part 410 are always inserted into the strip groove 321; at the same time, it can also limit the position of the slide part 410 to a certain extent, so as to prevent the slide part 410 from being separated from the open cavity 320. In a specific embodiment, the elastic member 432 can be a coil spring.

[0044] In a specific embodiment, the slide bar 431 includes a protruding block 4311, a limiting block 4312 and a guiding block 4313. The protruding block 4311 protrudes from the sliding part 410 and is inserted into the strip groove 321. The guiding block 4313 is arranged at the end of the elastic member 432 to provide guidance for the telescopic movement of the elastic member 432. The limiting block 4312 can abut against the inner wall of the accommodating cavity 411 to prevent the slide bar 431 from being separated from the sliding part 410 under the thrust of the elastic member 432. Among them, the protruding block 4311, the limiting block 4312 and the guiding block 4313 are all columnar structures, and the diameter of the protruding block 4311 is smaller than the diameter of the limiting block 4312, and the diameter of the guiding block 4313 is smaller than the inner diameter of the elastic member 432. It should be noted that in addition to the slide bar 431 and the strip groove 321 being used for guidance, the slide part 410 can also be guided by the cooperation of the slider and the slide rail.

[0045] See also Figure 2 and Figure 6 In one embodiment of the present invention, a reset member 412 is provided between the sliding portion 410 and the fixing belt 300; the reset member 412 drives the sliding portion 410 to slide in a direction close to the plug block 310, so as to drive the locking member 400 to switch to the locking position. In this embodiment, the reset member 412 can provide a thrust to drive the sliding portion 410 to slide in a direction close to the plug block 310, that is, to drive the locking member 400 to switch to the locking position and lock the position of the fixing belt 300. When installing the fixing belt 300, the user only needs to slide the locking member 400 to the unlocking position, insert the plug block 310 of the fixing belt 300 into the slot 210, and then release the locking member 400. The locking member 400 will automatically switch to the locking position under the thrust of the reset member 412 to lock the position of the fixing belt 300.
