Technical Field

[0001] The embodiments of the present application relate to the technical field of wearable devices, and in particular, to a watch band and a wearable electronic device. Background Art

[0002] When wearing a watch, it is necessary to adjust the length of the watch band by matching the buckle and the holes on the watch band to fit the wrist. However, the adjusted watch band may be too long or too short and cannot be adapted to the wrist circumference. Utility Model Content

[0003] The embodiments of the present application provide a watch band and a wearable electronic device, which can adjust the length of the watch band so that the watch band can be adapted to the wrist circumference.

[0004] In a first aspect, the embodiments of the present application provide a watch band, including: a first band body, a second band body, a structural member, and a moving member, wherein a first end of the first band body is used for detachably connecting with the second band body. The structural member is installed on the first end of the first band body, and the moving member is installed on the structural member. The structural member includes a first structural member and a second structural member, and the first structural member and the second structural member are connected to each other. The first structural member can move relative to the second structural member along a first direction through the moving member. At the same time, the structural member is converted between a first state and a second state. The first direction is the extending direction of the first band body. When the structural member is in the first state, the dimension of the structural member along the first direction is a first distance; when the structural member is in the second state, the dimension of the structural member along the first direction is a second distance, and the second distance is different from the first distance.

[0005] Through the above settings, during the conversion of the structural member between the first state and the second state, the first structural member can move relative to the second structural member along the first direction through the moving member, so as to change the dimension of the structural member along the extending direction of the first band body, thereby adjusting the length of the watch band so that the watch band can be adapted to the wrist circumference.

[0006] In some embodiments that may include the above embodiments, the first distance is less than the second distance.

[0007] In some embodiments that may include the above embodiments, the first distance is greater than the second distance.

[0008] In some embodiments that may include the above embodiments, the moving member includes a rotating member and a mating member. Among them, the rotating member is installed on the second structural member, and the mating member is installed on the first structural member. The mating member has a first end and a second end, and the first end and the second end of the mating member are spaced apart along a first direction. The first end of the mating member is used to connect to the first structure. The rotating member is connected to the mating member, and when the rotating member rotates relative to the second structural member, the mating member moves relative to the rotating member. In the first direction, when the structural member is in a first state, the spacing distance between the rotating member and the first end of the mating member is a third distance, and when the structural member is in a second state, the spacing distance between the rotating member and the first end of the mating member is a fourth distance. The third distance and the fourth distance are different.

[0009] With the above arrangement, the user can operate the rotating member to switch the structural member between the first state and the second state, thereby adjusting the length of the watch band.

[0010] In some embodiments that may include the above embodiments, the third distance is less than the fourth distance.

[0011] In some embodiments that may include the above embodiments, the third distance is greater than the fourth distance.

[0012] In some embodiments that may include the above embodiments, the rotating member and the mating member are connected by threads. With the above arrangement, the user can operate the rotating member to switch the structural member between the first state and the second state, thereby adjusting the length of the watch band. Moreover, when the operation of the rotating member stops, there is a thread friction force between the rotating member and the mating member, and the rotating member can limit the movement of the mating member in the first direction, so that the dimension of the structural member in the first direction remains unchanged, maintaining the wearing comfort.

[0013] In some embodiments that may include the above embodiments, the rotating member and the mating member are engaged. With the above arrangement, the transmission efficiency between the rotating member and the mating member is relatively high, and the cooperation is stable.

[0014] In some embodiments that may include the above embodiments, the second structural member includes a cover plate and a bottom plate, and the cover plate is connected to the bottom plate to jointly enclose a receiving cavity. Among them, the cover plate and the bottom plate are arranged opposite to each other, the bottom plate is used to contact the skin, and a first opening is provided on the cover plate. The first opening is communicated with the receiving cavity, and a part of the rotating member is located in the receiving cavity, and another part of the rotating member extends out of the receiving cavity from the opening. With the above arrangement, it is convenient to operate the rotating member.

[0015] In some embodiments that may include the above embodiments, a limiting groove is provided on the second structural member. The groove wall of the limiting groove includes a first limiting surface and a second limiting surface, and the first limiting surface and the second limiting surface are oppositely arranged along a first direction. The first structural member has a limiting protrusion, and the limiting protrusion is arranged in the limiting groove. During the conversion of the structural member between the first state and the second state, the limiting protrusion moves in the limiting groove. When the structural member is in the first state, the limiting protrusion contacts the first limiting surface; when the structural member is in the second state, the limiting protrusion contacts the second limiting surface. Through the above arrangement, the movement stroke of the first structural member relative to the second structural member can be limited.

[0016] In some embodiments that may include the above embodiments, the second limiting surface is closer to the first end of the first belt body than the first limiting surface.

[0017] In some embodiments that may include the above embodiments, the first limiting surface is closer to the first end of the first belt body than the second limiting surface.

[0018] In some embodiments that may include the above embodiments, the moving member includes an elastic member, and the elastic member is located between the first structural member and the second structural member. The first structural member and the second structural member are slidably connected. During the conversion of the structural member between the first state and the second state, the elastic member generates elastic deformation. In the first direction, when the structural member is in the first state, the size of the elastic member is a first size, and when the structural member is in the second state, the size of the elastic member is a second size. The first size and the second size are different.

[0019] Through the above arrangement, during the conversion of the structural member from the first state to the second state, the elastic member accumulates elastic potential energy, and the elastic member can convert the elastic potential energy into kinetic energy to drive the structural member to convert from the second state to the first state.

[0020] In some embodiments that may include the above embodiments, the first size is greater than the second size.

[0021] Through the above arrangement, during the conversion of the structural member from the first state to the second state, the first structural member and the second structural member compress the elastic member, and the elastic potential energy of the spring increases. During the conversion of the structural member from the second state to the first state, the elastic potential energy of the elastic member is converted into kinetic energy, and the elastic member drives the first structural member to move relative to the second structural member, so that the watch band tightens and fits the user's wrist, making the length of the watch band adapt to the user's wrist circumference and improving the wearing comfort.

[0022] In some embodiments that may include the above embodiments, the first size is less than the second size.

[0023] In some embodiments that may include the above embodiments, the first structural member and the second structural member are slidably connected by a chute and a slider. The chute extends in a first direction, and the second structural member can slide relative to the first structural member in the first direction. One of the first structural member and the second structural member includes the chute, and the other of the first structural member and the second structural member includes the slider. Through the above arrangement, the chute and the slider can limit the movement direction of the first structural member.

[0024] In some embodiments that may include the above embodiments, the groove wall of the chute includes a first groove wall and a second groove wall, and the first groove wall and the second groove wall are spaced apart in the first direction. The elastic member is located between the second groove wall and the slider.

[0025] Through the above arrangement, during the conversion of the structural member from the first state to the second state, the distance between the slider and the second groove wall changes, and the length dimension of the elastic member in the first direction changes, generating elastic deformation.

[0026] In some embodiments that may include the above embodiments, the first groove wall is closer to the first end of the first belt body than the second groove wall.

[0027] In some embodiments that may include the above embodiments, the second groove wall is closer to the first end of the first belt body than the first groove wall.

[0028] In some embodiments that may include the above embodiments, the second structural member is provided with a receiving cavity and a second opening communicating with the receiving cavity. A part of the first structural member extends into the receiving cavity through the second opening. During the conversion of the structural member between the first state and the second state, the part of the first structural member located in the receiving cavity changes. When the structural member is in the first state, the part of the first structural member located in the receiving cavity is the first part; when the structural member is in the second state, the part of the first structural member located in the receiving cavity is the second part. The length dimensions of the first part and the second part in the first direction are different.

[0029] Through the above arrangement, at least a part of the first structural member is inserted into the second structural member, and the assembly between the first structural member and the second structural member is compact, reducing the volume of the structural member.

[0030] In some embodiments that may include the above embodiments, the watch band includes a first fixing member, and the second belt body has a second fixing member. Wherein, the first fixing member is connected to the second structural member, and the first structural member is connected to the first end of the first belt body. The first fixing member and the second fixing member are detachably connected to detachably connect the first belt body and the second belt body.

[0031] Through the above arrangement, the first belt body and the second belt body are detachably connected by the first fixing member and the second fixing member, enabling the watch band to surround the user's wrist.

[0032] In some embodiments that may include the above embodiments, the first fixing member includes a watch buckle, and the second fixing member includes a plurality of watch holes. The plurality of watch holes are arranged at intervals along the extending direction of the second band. The watch buckle is used for mating and connecting with any one of the watch holes. Through the above arrangement, the watch hole that is mated and connected with the watch buckle can be replaced to adjust the length of the watch band.

[0033] In some embodiments that may include the above embodiments, the first structural member is rotatably connected to the first band, and the rotation axis of the first structural member relative to the first band is perpendicular to the first direction. Through the above arrangement, the range of movement of the structural member relative to the first band is expanded, and the wearing comfort is improved.

[0034] In some embodiments that may include the above embodiments, the second structural member is rotatably connected to the first fixing member, and the rotation axis of the second structural member relative to the first fixing member is perpendicular to the first direction. Through the above arrangement, the range of movement of the structural member relative to the first fixing member is expanded, and the wearing comfort is improved.

[0035] In a second aspect, an embodiment of the present application provides a wearable electronic device, including: a device body, and the watch band of any one of the above embodiments, wherein both the first band and the second band are connected to the device body, and the second end of the first band is connected to the device body.

[0036] Through the above arrangement, the user can switch the structural member between the first state and the second state to increase the length of the watch band, facilitate wearing or taking off the wearable electronic device; or decrease the length of the watch band to make the length of the watch band fit the wrist circumference and improve the wearing comfort.

[0065] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without creative efforts shall fall within the scope of protection of this application.

[0066] The embodiments of this application provide a wearable electronic device, which may include a smart watch, a sports watch, a smart bracelet, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, etc. The embodiments of this application do not limit the types and wearing parts of the wearable electronic device.

[0067] In the following embodiments of this application, a smart watch will be taken as an example for introduction. It can be understood that the wearable electronic device in the embodiments of this application is not limited to a smart watch.

[0068] Please refer to Figure 1 , the wearable electronic device 10 includes a watch band 20 and a device body 30. Among them, the device body 30 can be used to implement functions such as time display, timing, time reporting, message notification, motion detection, heart rate monitoring, blood oxygen level detection, etc.; the watch band 20 is connected to the device body 30, and the watch band 20 can be used to surround parts such as the user's wrist, ankle, upper arm, etc. to wear the device body 30 on the user's body. In the following embodiments, the wearable electronic device 10 being worn on the user's wrist will be taken as an example for introduction.

[0069] Please refer to Figure 2 , the watch band 20 includes a first band body 300 and a second band body 400, and the extending direction of the first band body 300 is the first direction x. Among them, one end of the first band body 300 on the left side along the first direction x is the first end of the first band body 300, and one end of the first band body 300 on the right side along the first direction x is the second end of the first band body 300; one end of the second band body 400 on the right side along the first direction x is the first end of the second band body 400, and one end of the second band body 400 on the left side along the first direction x is the second end. As Figure 1 shown, the second end of the first band body 300 is connected to the device body 30, and the second end of the second band body 400 is connected to the device body 30. The first band body 300 and the second band body 400 can be relatively arranged on both sides of the device body 30.

[0070] In some implementation manners, the materials for making the first band body 300 and the second band body 400 may include at least one of materials such as metal, leather, rubber, canvas, nylon, etc.

[0071] Please refer to Figure 2 . The watch band 20 has a first fixing member 500 which may be located at the first end of the first band body 300. The second band body 400 has a second fixing member 600 which may be located at the first end of the second band body 400. The first fixing member 500 and the second fixing member 600 are detachably connected to detachably connect the first band body 300 and the second band body 400, so that the watch band 20 can surround the user's wrist.

[0072] The embodiments of the present application do not limit the connection manner of the first fixing member 500 and the second fixing member 600.

[0073] For example, the first fixing member 500 and the second fixing member 600 may be snap-connected. Among them, the first fixing member 500 and the second fixing member 600 may both include at least one of a pin buckle, a butterfly buckle, a folding buckle, and a hook buckle. Exemplarily, in combination with Figure 2 and Figure 3 , the first fixing member 500 includes a watch buckle 510, and the second fixing member 600 includes a plurality of watch holes 610 which are arranged at intervals along the first direction x. The watch buckle 510 is used for detachably connecting with any one of the plurality of watch holes 610 to detachably connect the first band body 300 and the second band body 400.

[0074] Alternatively, the first fixing member 500 and the second fixing member 600 may also be bonded. Exemplarily, the first fixing member 500 includes a hook surface of Velcro, and the second fixing member 600 includes a fuzzy surface of Velcro. The hook surface of Velcro is used for bonding with the fuzzy surface of Velcro to detachably connect the first band body 300 and the second band body 400.

[0075] In the above embodiments, when the watch band 20 surrounds the user's wrist, the first fixing member 500 and the second fixing member 600 can be used to adjust the length of the watch band 20. Exemplarily, by replacing the watch hole 610 that cooperates with the watch buckle 510 to adjust the length of the watch band 20; by adjusting the bonding area between the hook surface of Velcro and the fuzzy surface of Velcro to adjust the length of the watch band 20. Thus, the length of the watch band 20 can be close to the user's wrist circumference.

[0076] Please refer to Figure 2 and Figure 3 . Based on the above structure, the watch band 20 of the embodiments of the present application further includes a structural member 100 and a moving member 200. Among them, the structural member 100 is installed at the first end of the first band body 300. The structural member 100 is connected to the first fixing member 500. The structural member 100 is located between the first band body 300 and the first fixing member 500. The moving member 200 is arranged on the structural member 100. Of course, the structural member 100 may also be installed at other positions. For example, it is installed at the second end of the first band body 300, or installed on the second band body 400.

[0077] The structural member 100 can be rotatably connected to the first belt body 300 to expand the range of movement of the structural member 100 relative to the first belt body 300 and improve wearing comfort. The structural member 100 can also be rotatably connected to the first fixing member 500 to expand the range of movement of the structural member 100 relative to the first fixing member 500 and improve wearing comfort.

[0078] Please continue to refer to Figure 2 and Figure 3 As shown in FIGS. and, the structural member 100 includes a first structural member 110 and a second structural member 120 that are connected to each other. In some implementation manners, both the first structural member 110 and the second structural member 120 can be made of at least one of materials such as metal (such as stainless steel, titanium alloy, etc.), ceramic, plastic, etc.

[0079] Among them, the first structural member 110 can be rotatably connected to the first belt body 300. At the same time, the second structural member 120 is rotatably connected to the first fixing member 500. In an embodiment where the first fixing member 500 includes a watch buckle 510, the watch buckle 510 further includes a needle body 512 and a buckle body 511. The watch band 20 further includes a first connecting shaft 700 and a second connecting shaft 800. Both ends of the first connecting shaft 700 are connected to the first structural member 110. The first connecting shaft 700 penetrates through the first belt body 300 to rotatably connect the first structural member 110 and the first belt body 300. Both ends of the second connecting shaft 800 are connected to the buckle body 511. The second connecting shaft 800 respectively penetrates through the second structural member 120 and the needle body 512 to rotatably connect the second structural member 120 and the first fixing member 500.

[0080] In an alternative embodiment, the first connecting shaft 700 can be parallel to the second direction y. The second direction y is perpendicular to the first direction x, and the second direction y can be parallel to the width direction of the first belt body 300. Thus, the rotation axis of the first structural member 110 relative to the first belt body 300 is perpendicular to the first direction x. The second connecting shaft 800 can be parallel to the second direction y. Thus, the rotation axis of the second structural member 120 relative to the first fixing member 500 is perpendicular to the first direction x.

[0081] Of course, the first structural member 110 can also be rotatably connected to the first fixing member 500. Correspondingly, the second structural member 120 can be rotatably connected to the first belt body 300.

[0082] Please refer to Figure 4 and Figure 5 As shown in FIGS. and, in the above embodiment, the first structural member 110 can move relative to the second structural member 120 along the first direction x through the moving member 200 (such as Figure 3 shown) to enable the structural member 100 to switch between a first state and a second state. When the structural member 100 is in the first state, the dimension of the structural member 100 in the first direction x is a first distance l 1; When the structural member 100 is in the second state, the dimension of the structural member 100 in the first direction x is the second distance l 2 . Among them, the first distance l 1 and the second distance l 2 are different. Correspondingly, the length of the watch band 20 when the structural member 100 is in the first state is different from the length of the watch band 20 when the structural member 100 is in the second state.

[0083] Through the above settings, the first structural member 110 moves relative to the second structural member 120 along the first direction x through the moving member 200, so that the dimension of the structural member 100 in the first direction x changes, thereby changing the length of the watch band 20. On the basis of adjusting the length of the watch band 20 through the first fixing member 500 and the second fixing member 600, the length of the watch band 20 is further adapted to the user's wrist circumference, improving the wearing comfort.

[0084] In the embodiment of the present application, the first distance l 1 can be less than the second distance l 2 . For example, please refer to Figure 6 and Figure 9 , the structural member 100 is in the first state, where the first state can be a contracted state; please refer to Figure 7 , Figure 8 and Figure 10 , the structural member 100 is in the second state, where the second state can be a stretched state. The user can make the structural member 100 transition from the first state to the second state to increase the length of the watch band 20 for easy wearing or removing of the wearable electronic device 10 (as shown in Figure 1 ). The user can also make the structural member 100 transition from the second state to the first state to reduce the length of the watch band 20, so that the length of the watch band 20 is adapted to the wrist circumference and the wearing comfort is improved.

[0085] Of course, in other alternative embodiments, the first distance l 1 can be greater than the second distance l 2 , correspondingly, the first state of the structural member 100 is a stretched state, and the second state of the structural member 100 is a contracted state. Only the case where the first distance l 1 is less than the second distance l 2 will be taken as an example to illustrate the motion state of the structural member 100 below.

[0086] In some embodiments, the first structural member 110 and the second structural member 120 can be slidably connected. Please refer to Figure 11, the second structural member 120 includes a receiving cavity 123 and a second opening 126, and the second opening 126 communicates with the receiving cavity 123. The receiving cavity 123 extends along the first direction x, and the orientation of the second opening 126 is parallel to the first direction x. The first structural member 110 is slidably disposed in the second opening 126, and a part of the first structural member 110 extends into the receiving cavity 123 through the second opening 126.

[0087] During the process of the structural member 100 transitioning between the first state and the second state, the length dimension of the part of the first structural member 110 located in the receiving cavity 123 changes along the first direction x. That is, when the structural member 100 is in the first state, the part of the first structural member 110 located in the receiving cavity 123 is the first part; when the structural member 100 is in the second state, the part of the first structural member 110 located in the receiving cavity 123 is the second part, and the length dimension of the second part along the first direction x is different from the length dimension of the first part along the first direction x. For example, the length dimension of the first part along the first direction x may be greater than the length dimension of the second part along the first direction x. Or, the length dimension of the first part along the first direction x may also be less than the length dimension of the second part along the first direction x.

[0088] Based on the above settings, at least a part of the first structural member 110 is inserted into the second structural member 120, and the assembly between the first structural member 110 and the second structural member 120 is compact, reducing the volume of the structural member 100.

[0089] In an alternative embodiment, please refer to Figure 12 and Figure 13 , the moving member 200 (as shown in Figure 3 ) includes an elastic member 210, and the elastic member 210 is disposed between the first structural member 110 and the second structural member 120. The elastic member 210 is used to contact the first structural member 110 and the second structural member 120 respectively. In some embodiments, the elastic member 210 may be connected to at least one of the first structural member 110 and the second structural member 120. The number of elastic members 210 is not limited in the embodiments of the present application. The elastic member 210 may include at least one object capable of elastic deformation such as a spring, an airbag, rubber, etc. During the process of the structural member 100 transitioning between the first state and the second state, the first structural member 110 and the second structural member 120 stretch or compress the elastic member 210, and the elastic member 210 undergoes elastic deformation, and the dimension of the elastic member 210 in the first direction x changes.

[0090] Please refer to Figure 14 , when the structural member 100 is in the first state, the dimension of the elastic member 210 in the first direction x is the first dimension l 3 ; please refer to Figure 15 , when the structural member 100 is in the second state, the dimension of the elastic member 210 in the first direction x is the second dimension l4 The first dimension l 3 and the second dimension l 4 are different.

[0091] Through the above settings, during the process of the structural member 100 transitioning from the first state to the second state, the elastic member 210 accumulates elastic potential energy, and the elastic member 210 can convert the elastic potential energy into kinetic energy to drive the structural member 100 to transition from the second state to the first state.

[0092] In an alternative embodiment, the first dimension l 3 can be greater than the second dimension l 4 .

[0093] Based on the above settings, in combination with Figure 14 and Figure 15 , during the process of the structural member 100 transitioning from the first state to the second state, the first structural member 110 and the second structural member 120 compress the elastic member 210, and the elastic potential energy of the spring increases. During the process of the structural member 100 transitioning from the second state to the first state, the elastic potential energy of the elastic member 210 is converted into kinetic energy, and the elastic member 210 drives the first structural member 110 to move relative to the second structural member 120, so that the watch band 20 (as shown in Figure 1 ) tightens and fits around the user's wrist, making the length of the watch band 20 adapt to the user's wrist circumference and improving the wearing comfort.

[0094] In another alternative embodiment, the first dimension l 3 can be less than the second dimension l 4 .

[0095] In the above embodiment, please refer back to Figure 7 and Figure 8 , the user can drive the structural member 100 to transition from the first state to the second state by pulling the first band body 300. F in the figure is the direction of a possible pulling force, and the pulling force F can be parallel to the first direction x.

[0096] In the above embodiment, when the structural member 100 is in the first state, the elastic member 210 may or may not undergo elastic deformation; when the structural member 100 is in the second state, the elastic member 210 may or may not undergo elastic deformation.

[0097] For example, when the structural member 100 is in the first state, the elastic member 210 does not undergo elastic deformation. When the structural member 100 is in the second state, the elastic member 210 undergoes elastic deformation. Alternatively, when the structural member 100 is in the first state, the elastic member 210 undergoes elastic deformation. When the structural member 100 is in the second state, the elastic member 210 does not undergo elastic deformation. Or, when the structural member 100 is in the first state and the second state, the elastic member 210 undergoes elastic deformation in both cases. In the above examples, the elastic deformation may include at least one of compression deformation, tensile deformation, bending deformation, and torsional deformation.

[0098] Please refer back to Figure 13 , in the embodiment of the present application, the first structural member 110 and the second structural member 120 are slidably connected through the chute 111 and the slider 125. Among them, the chute 111 may be provided on the first structural member 110. Correspondingly, the slider 125 is provided on the second structural member 120. Or, the slider 125 may be provided on the first structural member 110. Correspondingly, the chute 111 is provided on the second structural member 120. Please continue to refer to Figure 14 , the chute 111 extends along the first direction x, and the slider 125 is located within the chute 111. The chute 111 includes a first groove wall 112 and a second groove wall 113 arranged along the first direction x, and includes a third groove wall 114 and a fourth groove wall 115 arranged along the second direction y. The second direction is perpendicular to the first direction x.

[0099] When the structural member 100 is in the first state, the slider 125 is close to one of the first groove wall 112 and the second groove wall 113; when the structural member 100 is transitioning from the first state to the second state, the slider 125 moves along the first direction x within the chute 111; when the structural member 100 is in the second state, the slider 125 is close to the other of the first groove wall 112 and the second groove wall 113.

[0100] Based on the above settings, the elastic member 210 may be located between the second groove wall 113 and the slider 125. One end of the elastic member 210 may be in contact with the second groove wall 113, and the other end of the elastic member 210 may be in contact with the slider 125. During the process of the structural member 100 transitioning from the first state to the second state, the distance between the slider 125 and the second groove wall 113 changes, and the length dimension of the elastic member 210 along the first direction x changes.

[0101] In an alternative embodiment, the first groove wall 112 may be closer to the first end of the first belt body 300 (please refer to Figure 3 ) relative to the second groove wall 113. As Figure 14 shown, when the structural member 100 is in the first state, the slider 125 is closer to the first groove wall 112 relative to the second groove wall 113, and the slider 125 may be in contact with the first groove wall 112; please refer to Figure 14 andFigure 15 When the structural member 100 is converted from the first state to the second state, the slider 125 moves toward the second groove wall 113 while compressing the elastic member 210; as Figure 15 shown, when the structural member 100 is in the second state, the slider 125 is closer to the second groove wall 113 relative to the first groove wall 112, and the slider 125 can contact the second groove wall 113.

[0102] In another alternative embodiment, the second groove wall 113 can be closer to the first end of the first belt body 300 relative to the first groove wall 112.

[0103] The embodiments of the present application do not limit the number of the chute 111 and the slider 125. In the embodiments of the present application, both the chute 111 and the slider 125 are two to improve the stability when the first structural member 110 and the second structural member 120 move relative to each other. In other embodiments, both the chute 111 and the slider 125 can be set to one, three or more. The number of the sliders 125 can be the same as the number of the chutes 111, or the number of the sliders 125 can be different from the number of the chutes 111.

[0104] The embodiments of the present application do not limit the positions of the chute 111 and the slider 125. In the embodiments of the present application, the two chutes 111 are respectively arranged on both sides of the second structural member 120. In other embodiments, the chute 111 can also be arranged close to the middle of the second structural member 120.

[0105] The embodiments of the present application also provide another structural member 100 and another moving member 200. As Figure 16 and Figure 19 shown, the structural member 100 is in the first state. As Figure 17 、 Figure 18 and Figure 20 shown, the structural member 100 is in the second state.

[0106] In the above embodiments, please refer to Figure 21 and Figure 22 , the moving member 200 includes a rotating member 220 and a cooperating member 230, and the rotating member 220 is connected to the cooperating member 230. The embodiments of the present application do not limit the number of the rotating member 220 and the cooperating member 230.

[0107] In the embodiments of the present application, the rotating member 220 is rotatably mounted on the second structural member 120, and the cooperating member 230 is mounted on the first structural member 110. In other embodiments, the rotating member 220 can also be mounted on the first structural member 110, and correspondingly, the cooperating member 230 is mounted on the second structural member 120. Here, "mounted" can be understood as "arranged on", "connected to", "limited to", etc., and the embodiments of the present application do not limit the mounting manner of the rotating member 220 mounted on the second structural member 120.

[0108] In the embodiments of the present application, there is no limitation on the installation positions of the rotating member 220 and the mating member 230. In the embodiments of the present application, the rotating member 220 is disposed near the middle of the second structural member 120, and the mating member 230 is disposed near the middle of the first structural member 110. In other embodiments, the rotating member 220 may be disposed near any side of the second structural member 120, and the mating member 230 may be disposed near any side of the first structural member 110.

[0109] Please refer to Figure 23 , the mating member 230 has a first end and a second end. Among them, the first end of the mating member 230 is used to connect to the first structural member 110, and the second end of the mating member 230 is a free end. The direction in which the first end of the mating member 230 points to the second end of the mating member 230 is parallel to the first direction x. The mating member 230 may extend in a straight line. Based on this, the extending direction of the mating member 230 is parallel to the first direction x.

[0110] The rotating member 220 is used to rotate relative to the second structural member 120 to drive the mating member 230 to move relative to the rotating member 220 along the first direction x, thereby driving the first structural member 110 to move relative to the second structural member 120 along the first direction x. Based on the above settings, the user can operate the rotating member 220 to switch the structural member 100 between the first state and the second state.

[0111] In the above embodiments, the distance between the rotating member 220 and the first end of the mating member 230 changes. As Figure 23 shown, when the structural member 100 is in the first state, in the first direction x, the distance between the rotating member 220 and the first end of the mating member 230 is the third distance l 5 ; as Figure 24 shown, when the structural member 100 is in the second state, in the first direction x, the distance between the rotating member 220 and the first end of the mating member 230 is the fourth distance l 6 . The third distance l 5 is different from the fourth distance l 6 .

[0112] In an alternative embodiment, the third distance l 5 may be less than the fourth distance l 6 . Please refer to Figure 23 and Figure 24 , during the process of the structural member 100 transitioning from the first state to the second state, the first end of the mating member 230 moves away from the rotating member 220.

[0113] In another alternative embodiment, the third distance l 5 may be greater than the fourth distance l 6 .

[0114] In an alternative embodiment, the rotating member 220 and the mating member 230 are threadedly connected. Among them, one of the rotating member 220 and the mating member 230 has an internal thread, and the other has an external thread. In the embodiment of the present application, the rotating member 220 may have an internal thread, and the mating member 230 may have an external thread. In other embodiments, the rotating member 220 may have an external thread, and the mating member 230 may have an internal thread.

[0115] With the above arrangement, the user can adjust the size of the structural member 100 in the first direction x by operating the rotating member 220, so that the length of the watch band 20 (as Figure 1 shown) adapts to the wrist circumference. When the operation of the rotating member 220 stops, there is a thread friction force between the rotating member 220 and the mating member 230, and the rotating member 220 can limit the movement of the mating member 230 in the first direction x, so that the size of the structural member 100 in the first direction x remains unchanged, maintaining the wearing comfort.

[0116] In another alternative embodiment, the rotating member 220 and the mating member 230 are meshed. For example, the rotating member 220 may include a gear, and the mating member 230 may include a rack.

In other implementation manners, the cover plate 121 and the bottom plate 122 are non-detachably connected. For example, the cover plate 121 and the bottom plate 122 are riveted; or, the cover plate 121 and the bottom plate 122 are bonded.

[0118] When worn, at least one of the bottom plate 122 and the cover plate 121 can be used to contact the skin. For example, the bottom plate 122 can be used to contact the skin. Based on the above structure, please refer to Figure 22 , the bolt 128 can be provided on the bottom plate 122. Thus, the bolt 128 can be covered between the bottom plate 122 and the skin to improve the decorative effect. The bolt 128 can also be provided on the cover plate 121 to prevent scratching the skin.

[0119] The cover plate 121 and the bottom plate 122 jointly enclose an accommodation cavity 123 (please refer to Figure 11), at least one of the cover plate 121 and the bottom plate 122 has a first opening 124 communicating with the accommodating cavity 123. For example, there is one first opening 124, and the first opening 124 is provided on one of the cover plate 121 and the bottom plate 122. Alternatively, both the cover plate 121 and the bottom plate 122 have a first opening 124, and the first opening 124 provided on the cover plate 121 and the first opening 124 provided on the bottom plate 122 are arranged oppositely.

[0120] A part of the rotating member 220 is located in the accommodating cavity 123, and another part of the rotating member 220 extends out of the accommodating cavity 123 from the first opening 124 for the convenience of user operation. The edge of the first opening 124 can abut against the rotating member 220 to limit the movement of the rotating member 220 in the first direction x, and further mount the rotating member 220 on the second structural member 120.

[0121] In some implementation manners, the rotating member 220 may be provided with knurling for the convenience of user operation.

When the first structural member 110 moves relative to the second structural member 120, the limiting protrusion 116 moves in the limiting groove 127. The limiting groove 127 has a first limiting surface 1271 and a second limiting surface 1272, and the first limiting surface 1271 and the second limiting surface 1272 are arranged oppositely along the first direction x. Both the first limiting surface 1271 and the second limiting surface 1272 are used to contact the limiting protrusion 116 to limit the stroke of the first structural member 110.

[0123] As Figure 23 shown, when the structural member 100 is in the first state, the limiting protrusion 116 contacts the first limiting surface 1271; please combine Figure 23 and Figure 24 , when the structural member 100 is converted from the first state to the second state, the limiting protrusion 116 moves from the first limiting surface 1271 to the second limiting surface 1272; as Figure 24 shown, when the structural member 100 is in the second state, the limiting protrusion 116 contacts the second limiting surface 1272.
