Description

Watch straps and wearable electronic devices Technical Field

[0001] This application relates to the field of wearable device technology, specifically to a watch strap and wearable electronic devices. Background Technology

[0002] When wearing a watch, the length of the strap needs to be adjusted using the buckle and the holes on the strap to fit the wrist. However, the adjusted strap may be too long or too short and not fit the wrist circumference.

[0003] Utility Model Content

[0004] This application provides a watch strap and a wearable electronic device, which can adjust the length of the watch strap to fit the wrist circumference.

[0005] In a first aspect, embodiments of this application provide a watch strap, including: a first strap body, a second strap body, a structural member, and a moving member, wherein a first end of the first strap body is detachably connected to the second strap body. The structural member is mounted on the first end of the first strap body, and the moving member is mounted on the structural member. The structural member includes a first structural member and a second structural member, which are interconnected. The first structural member can move relative to the second structural member along a first direction via the moving member, and the structural member can switch between a first state and a second state. The first direction is the extension direction of the first strap body. When the structural member is in the first state, its dimension along the first direction is a first distance; when the structural member is in the second state, its dimension along the first direction is a second distance, which is different from the first distance.

[0006] With the above settings, during the transition between the first and second states, the first structural component can move relative to the second structural component in the first direction via the moving component to change the size of the structural component along the extension direction of the first strap body, thereby adjusting the length of the watch strap so that the watch strap can fit the wrist circumference.

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

[0008] In some embodiments that may include the above embodiments, the first distance is greater than the second distance.

[0009] In some embodiments that may include the above-described embodiments, the moving component includes a rotating component and a mating component. The rotating component is mounted on a second structural component, and the mating component is mounted on a first structural component. The mating component has a first end and a second end, which are spaced apart along a first direction. The first end of the mating component is used to connect with the first structure. The rotating component is connected to the mating component, and when the rotating component rotates relative to the second structural component, the mating component moves relative to the rotating component. In the first direction, when the structural component is in a first state, the distance between the rotating component and the first end of the mating component is a third distance; when the structural component is in a second state, the distance between the rotating component and the first end of the mating component is a fourth distance. The third distance and the fourth distance are different.

[0010] With the above settings, users can adjust the length of the watch strap by operating the rotating component to switch the structural component between the first and second states.

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

[0012] In some embodiments that may include the above embodiments, the third distance is greater than the fourth distance.

[0013] In some embodiments that may include the above-described examples, the rotating component and the mating component are threadedly connected. With this configuration, the user can adjust the length of the watch strap by operating the rotating component to switch the structural component between a first state and a second state. Furthermore, when the rotating component is stopped, there is threaded friction between the rotating component and the mating component. The rotating component restricts the movement of the mating component in the first direction, keeping the dimensions of the structural component unchanged in the first direction and maintaining wearing comfort.

[0014] In some embodiments that may include the above-described examples, the rotating component and the mating component are engaged. With this configuration, the transmission efficiency between the rotating component and the mating component is high, and the engagement is smooth.

[0015] In some embodiments that may include the above-described embodiments, the second structural member includes a cover plate and a bottom plate, which are connected to form a receiving cavity. The cover plate and bottom plate are disposed opposite to each other, with the bottom plate for contact with the skin. The cover plate has a first opening. The first opening communicates with the receiving cavity, with a portion of the rotating member located within the receiving cavity and another portion extending out of the receiving cavity from the opening. This arrangement facilitates the operation of the rotating member.

[0016] In some embodiments that may include the above-described embodiments, the second structural member is provided with a limiting groove, the groove wall of which includes a first limiting surface and a second limiting surface, which are disposed opposite to each other along a first direction. The first structural member has a limiting protrusion disposed within the limiting groove. During the transition between the first and second states of the structural member, the limiting protrusion moves within 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.

[0017] 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.

[0018] 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.

[0019] In some embodiments that may include the above-described embodiments, the moving member includes an elastic member located between the first structural member and the second structural member. The first and second structural members are slidably connected. During the transition between the first and second states of the structural member, the elastic member undergoes elastic deformation. In a first direction, when the structural member is in the first state, the elastic member has a first dimension; when the structural member is in the second state, the elastic member has a second dimension. The first and second dimensions are different.

[0020] With the above settings, during the transition of the structural component from the first state to the second state, the elastic component accumulates elastic potential energy, which can be converted into kinetic energy to drive the structural component to transition from the second state to the first state.

[0021] In some embodiments that may include the above embodiments, the first dimension is larger than the second dimension.

[0022] With the above setup, during the transition from the first state to the second state of the structural component, the first and second structural components compress the elastic component, increasing the elastic potential energy of the spring. During the transition from the second state to the first state, the elastic potential energy of the elastic component is converted into kinetic energy. The elastic component drives the first structural component to move relative to the second structural component, tightening the watch strap and fitting it snugly against the user's wrist, thus adapting the strap length to the user's wrist circumference and improving wearing comfort.

[0023] In some embodiments that may include the above embodiments, the first dimension is smaller than the second dimension.

[0024] In some embodiments that may include the above-described examples, the first structural member and the second structural member are slidably connected by a groove and a slider. The groove extends along a first direction, and the second structural member can slide relative to the first structural member along the first direction. One of the first and second structural members includes a groove, and the other of the first and second structural members includes a slider. With the above arrangement, the groove and slider can limit the direction of movement of the first structural member.

[0025] In some embodiments that may include the above-described embodiments, the groove wall includes a first groove wall and a second groove wall, which are spaced apart along a first direction. An elastic element is located between the second groove wall and the slider.

[0026] With the above settings, during the transition of the structural component 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 component along the first direction changes, resulting in elastic deformation.

[0027] 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.

[0028] 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.

[0029] In some embodiments that may include the above-described embodiments, the second structural member has a receiving cavity and a second opening communicating with the receiving cavity. A portion of the first structural member extends into the receiving cavity through the second opening. During the transition between the first state and the second state of the structural member, the portion of the first structural member located within the receiving cavity changes. When the structural member is in the first state, the portion of the first structural member located within the receiving cavity is the first portion; when the structural member is in the second state, the portion of the first structural member located within the receiving cavity is the second portion. The first portion and the second portion have different lengths in a first direction.

[0030] With the above arrangement, the first structural component is at least partially inserted into the second structural component, and the first and second structural components are tightly assembled, reducing the volume of the structural components.

[0031] In some embodiments that may include the above-described embodiments, the watch strap includes a first fastener, and a second strap body has a second fastener. The first fastener is connected to a second structural member, and the first structural member is connected to a first end of the first strap body. The first fastener and the second fastener are detachably connected to detachably connect the first strap body and the second strap body.

[0032] With the above configuration, the first strap body and the second strap body are detachably connected by the first fixing member and the second fixing member, so that the watch strap can wrap around the user's wrist.

[0033] In some embodiments that may include the above-described examples, the first fastener includes a watch buckle, and the second fastener includes a plurality of watch holes spaced apart along the extension direction of the second strap. The watch buckle is used to engage with any one of the watch holes. With this configuration, the watch holes engaging with the watch buckle can be changed to adjust the length of the watch strap.

[0034] In some embodiments that may include the above-described examples, the first structural member and the first belt body are rotatably connected, and the rotation axis of the first structural member relative to the first belt body is perpendicular to the first direction. This arrangement expands the range of motion of the structural member relative to the first belt body, improving wearing comfort.

[0035] In some embodiments that may include the above-described examples, the second structural member and the first fixing member are rotatably connected, and the rotation axis of the second structural member relative to the first fixing member is perpendicular to the first direction. This arrangement expands the range of motion of the structural member relative to the first fixing member, improving wearing comfort.

[0036] Secondly, embodiments of this application provide a wearable electronic device, including: a device body, and a watch strap according to any of the above embodiments, wherein a first strap body and a second strap body are both connected to the device body, and a second end of the first strap body is connected to the device body.

[0037] With the above settings, users can switch the structural components between the first and second states to increase the length of the watch band, making it easier to wear or remove wearable electronic devices; or to decrease the length of the watch band, making the length of the watch band fit the wrist circumference and improving wearing comfort.

Detailed Implementation

[0063] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all possible embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0064] This application provides a wearable electronic device, which may include smartwatches, sports watches, smart bracelets, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, etc. This application does not limit the type of wearable electronic device or the wearing part.

[0065] The following embodiments of this application will use a smartwatch as an example of a wearable electronic device. It should be understood that the wearable electronic device in the embodiments of this application is not limited to a smartwatch.

[0066] Referring to Figure 1, the wearable electronic device 10 includes a watch strap 20 and a device body 30. The device body 30 can be used to perform functions such as time display, timing, time announcement, message notification, motion detection, heart rate monitoring, and blood oxygen level detection. The watch strap 20 is connected to the device body 30 and can be wrapped around the user's wrist, ankle, upper arm, etc., to wear the device body 30 on the user's body. The following embodiment will use the example of the wearable electronic device 10 being worn on the user's wrist as an example.

[0067] Referring to Figure 2, the watch strap 20 includes a first strap body 300 and a second strap body 400. The first strap body 300 extends in a first direction x. Specifically, the left end of the first strap body 300 along the first direction x is its first end, and the right end is its second end. Similarly, the right end of the second strap body 400 along the first direction x is its first end, and the left end is its second end. As shown in Figure 1, the second end of both the first and second strap bodies 300 and 400 are connected to the device body 30. The first and second strap bodies 300 can be positioned opposite each other on either side of the device body 30.

[0068] In some implementations, the materials used to make the first belt 300 and the second belt 400 may include at least one of the following: metal, leather, rubber, canvas, nylon, etc.

[0069] Referring to Figure 2, the watch strap 20 has a first fastener 500, which can be located at a first end of the first strap body 300. The second strap body 400 has a second fastener 600, which can be located at a first end of the second strap body 400. The first fastener 500 and the second fastener 600 are detachably connected to detachably connect the first strap body 300 and the second strap body 400, allowing the watch strap 20 to wrap around the user's wrist.

[0070] The embodiments of this application do not limit the connection method of the first fastener 500 and the second fastener 600.

[0071] For example, the first fastener 500 can be snapped together with the second fastener 600. Both the first fastener 500 and the second fastener 600 can include at least one of a pin buckle, butterfly buckle, folding buckle, or hook buckle. For example, referring to Figures 2 and 3, the first fastener 500 includes a watch buckle 510, and the second fastener 600 includes a plurality of watch holes 610, which are spaced apart along a first direction x. The watch buckle 510 is used for detachable connection with any one of the plurality of watch holes 610 to detachably connect the first strap body 300 and the second strap body 400.

[0072] Alternatively, the first fastener 500 can also be bonded to the second fastener 600. For example, the first fastener 500 includes a hook and loop fastener side, and the second fastener 600 includes a loop fastener side, the hook and loop fastener side being bonded to the loop fastener side for detachable connection of the first strap 300 and the second strap 400.

[0073] In the above embodiment, when the watch strap 20 is wrapped around the user's wrist, the first fastener 500 and the second fastener 600 can be used to adjust the length of the watch strap 20. For example, the length of the watch strap 20 can be adjusted by changing the hole 610 that mates with the buckle 510; the length of the watch strap 20 can also be adjusted by adjusting the adhesive area of ​​the hook and loop sides of the Velcro. Thus, the length of the watch strap 20 can be approximately equal to the user's wrist circumference.

[0074] Referring to Figures 2 and 3, based on the above structure, the watch strap 20 of this embodiment further includes a structural member 100 and a moving member 200. The structural member 100 is mounted on the first end of the first strap body 300, connected to the first fixing member 500, and located between the first strap body 300 and the first fixing member 500. The moving member 200 is disposed on the structural member 100. Of course, the structural member 100 can also be mounted in other locations, for example, on the second end of the first strap body 300, or on the second strap body 400.

[0075] The structural component 100 can be rotatably connected to the first belt body 300 to expand the range of motion of the structural component 100 relative to the first belt body 300 and improve wearing comfort. The structural component 100 can also be rotatably connected to the first fixing component 500 to expand the range of motion of the structural component 100 relative to the first fixing component 500 and improve wearing comfort.

[0076] Please refer to Figures 2 and 3. The structural member 100 includes a first structural member 110 and a second structural member 120 that are interconnected. In some implementations, both the first structural member 110 and the second structural member 120 may be made of at least one of the following materials: metal (such as stainless steel, titanium alloy, etc.), ceramic, plastic, etc.

[0077] In this design, the first structural member 110 is rotatably connected to the first strap 300, while 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 buckle 510, the buckle 510 further includes a pin 512 and a buckle body 511, and the strap 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, and the first connecting shaft 700 passes through the first strap 300 to rotatably connect the first structural member 110 and the first strap 300. Both ends of the second connecting shaft 800 are connected to the buckle body 511, and the second connecting shaft 800 passes through the second structural member 120 and the pin 512 respectively to rotatably connect the second structural member 120 and the first fixing member 500.

[0078] In one alternative embodiment, the first connecting shaft 700 may be parallel to the second direction y. The second direction y is perpendicular to the first direction x, and may be parallel to the width direction of the first belt 300. Thus, the axis of rotation of the first structural member 110 relative to the first belt 300 is perpendicular to the first direction x. The second connecting shaft 800 may be parallel to the second direction y, thereby the axis of rotation of the second structural member 120 relative to the first fixing member 500 is perpendicular to the first direction x.

[0079] Of course, the first structural member 110 can also be rotatably connected to the first fixing member 500, and correspondingly, the second structural member 120 can be rotatably connected to the first belt body 300.

[0080] Referring to Figures 4 and 5, in the above embodiment, the first structural member 110 can move relative to the second structural member 120 along a first direction x via the moving member 200 (as shown in Figure 3), so that the structural member 100 can switch between a first state and a second state. When the structural member 100 is in the first state, its dimension in the first direction x is a first distance l1; when the structural member 100 is in the second state, its dimension in the first direction x is a second distance l2. The first distance l1 and the second distance l2 are different. Correspondingly, the length of the watch strap 20 when the structural member 100 is in the first state is different from the length of the watch strap 20 when the structural member 100 is in the second state.

[0081] With the above settings, the first structural member 110 moves relative to the second structural member 120 along the first direction x via the moving member 200, thereby changing the size of the structural member 100 in the first direction x, thus changing the length of the watch strap 20. Based on the adjustment of the length of the watch strap 20 by the first fixing member 500 and the second fixing member 600, the length of the watch strap 20 is further adapted to the user's wrist circumference, improving wearing comfort.

[0082] In this embodiment, the first distance l1 can be less than the second distance l2. For example, referring to Figures 6 and 9, the structural member 100 is in a first state, which can be a retracted state; referring to Figures 7, 8, and 10, the structural member 100 is in a second state, which can be a stretched state. The user can change the structural member 100 from the first state to the second state to increase the length of the watch strap 20, making it easier to wear or remove the wearable electronic device 10 (as shown in Figure 1). The user can also change the structural member 100 from the second state to the first state to decrease the length of the watch strap 20, making the length of the watch strap 20 fit the wrist circumference and improving wearing comfort.

[0083] Of course, in other alternative embodiments, the first distance l1 can be greater than the second distance l2. Accordingly, 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. The following description only uses the example of the first distance l1 being less than the second distance l2 to illustrate the motion state of the structural member 100.

[0084] In some embodiments, the first structural member 110 and the second structural member 120 are slidably connected. Referring to FIG11, the second structural member 120 includes a receiving cavity 123 and a second opening 126, the second opening 126 communicating with the receiving cavity 123. The receiving cavity 123 extends along a 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 within the second opening 126, and a portion of the first structural member 110 extends into the receiving cavity 123 through the second opening 126.

[0085] During the transition between the first and second states of structural member 100, the length of the portion of the first structural member 110 located within the accommodating cavity 123 changes along the first direction x. That is, when structural member 100 is in the first state, the portion of the first structural member 110 located within the accommodating cavity 123 is the first part; when structural member 100 is in the second state, the portion of the first structural member 110 located within the accommodating cavity 123 is the second part, and the length of the second part along the first direction x differs from that of the first part along the first direction x. For example, the length of the first part along the first direction x can be greater than that of the second part along the first direction x. Alternatively, the length of the first part along the first direction x can be less than that of the second part along the first direction x.

[0086] Based on the above configuration, the first structural member 110 is at least partially inserted into the second structural member 120, and the first structural member 110 and the second structural member 120 are assembled compactly, reducing the volume of the structural member 100.

[0087] In an optional embodiment, referring to Figures 12 and 13, the moving member 200 (as shown in Figure 3) includes an elastic member 210, which 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 this application embodiment. The elastic member 210 may include at least one object capable of elastic deformation, such as a spring, an air bladder, or rubber. During the transition between the first state and the second state of the structural member 100, the first structural member 110 and the second structural member 120 stretch or compress the elastic member 210, causing the elastic member 210 to undergo elastic deformation, and the dimension of the elastic member 210 changes in the first direction x.

[0088] Referring to Figure 14, when the structural member 100 is in the first state, the elastic member 210 has a first dimension l3 in the first direction x; referring to Figure 15, when the structural member 100 is in the second state, the elastic member 210 has a second dimension l4 in the first direction x. The first dimension l3 and the second dimension l4 are different.

[0089] With the above settings, during the transition of structural component 100 from the first state to the second state, elastic component 210 accumulates elastic potential energy, which can be converted into kinetic energy to drive structural component 100 to transition from the second state to the first state.

[0090] In one alternative embodiment, the first dimension l3 may be larger than the second dimension l4.

[0091] Based on the above setup, referring to Figures 14 and 15, during the transition of structural component 100 from the first state to the second state, the first structural component 110 and the second structural component 120 compress the elastic component 210, increasing the elastic potential energy of the spring. During the transition of structural component 100 from the second state to the first state, the elastic potential energy of the elastic component 210 is converted into kinetic energy. The elastic component 210 drives the first structural component 110 to move relative to the second structural component 120, causing the watch strap 20 (as shown in Figure 1) to tighten and conform to the user's wrist, making the length of the watch strap 20 suitable for the user's wrist circumference and improving wearing comfort.

[0092] In another alternative embodiment, the first dimension l3 may be smaller than the second dimension l4.

[0093] In the above embodiments, please refer again to Figures 7 and 8. The user can drive the structural member 100 from the first state to the second state by pulling the first belt 300. In the figures, F represents a possible direction of the pulling force, which can be parallel to the first direction x.

[0094] In the above embodiments, 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.

[0095] For example, when structural member 100 is in the first state, elastic member 210 does not undergo elastic deformation; when structural member 100 is in the second state, elastic member 210 undergoes elastic deformation. Alternatively, when structural member 100 is in the first state, elastic member 210 undergoes elastic deformation; when structural member 100 is in the second state, elastic member 210 does not undergo elastic deformation. Or, when structural member 100 is in both the first and second states, elastic member 210 undergoes elastic deformation. In the above examples, elastic deformation may include at least one of compressive deformation, tensile deformation, bending deformation, and torsional deformation.

[0096] Please refer back to Figure 13. In this embodiment, the first structural member 110 and the second structural member 120 are slidably connected via a groove 111 and a slider 125. The groove 111 can be located on the first structural member 110, and correspondingly, the slider 125 is located on the second structural member 120. Alternatively, the slider 125 can be located on the first structural member 110, and correspondingly, the groove 111 is located on the second structural member 120. Continuing to refer to Figure 14, the groove 111 extends along a first direction x, and the slider 125 is located within the groove 111. The groove 111 includes a first groove wall 112 and a second groove wall 113 arranged along the first direction x, and a third groove wall 114 and a fourth groove wall 115 arranged along a second direction y. The second direction is perpendicular to the first direction x.

[0097] When the structural component 100 is in the first state, the slider 125 approaches one of the first groove wall 112 and the second groove wall 113; when the structural component 100 transitions from the first state to the second state, the slider 125 moves along the first direction x in the slide groove 111; when the structural component 100 is in the second state, the slider 125 approaches the other of the first groove wall 112 and the second groove wall 113.

[0098] Based on the above configuration, the elastic element 210 can be located between the second groove wall 113 and the slider 125. One end of the elastic element 210 can abut against the second groove wall 113, and the other end of the elastic element 210 can abut against the slider 125. During the transition of the structural component 100 from the first state to the second state, the distance between the slider 125 and the second groove wall 113 changes, and the length of the elastic element 210 along the first direction x changes.

[0099] In an alternative embodiment, the first groove wall 112 may be closer to the first end of the first belt 300 (refer to FIG. 3) relative to the second groove wall 113. As shown in FIG. 14, 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 contact the first groove wall 112; referring to FIG. 14 and FIG. 15, when the structural member 100 transitions 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 shown in FIG. 15, 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 may contact the second groove wall 113.

[0100] In another alternative embodiment, the second groove wall 113 may be closer to the first end of the first belt 300 relative to the first groove wall 112.

[0101] The embodiments of this application do not limit the number of slides 111 and sliders 125. In this embodiment, there are two slides 111 and two sliders 125 to improve the stability of the first structural member 110 and the second structural member 120 during relative movement. In other embodiments, there may be one slide 111 and three or more sliders 125. The number of sliders 125 may be the same as the number of slides 111, or the number of sliders 125 may be different from the number of slides 111.

[0102] The embodiments of this application do not limit the positions of the slide groove 111 and the slider 125. In this embodiment, the two slide grooves 111 are respectively provided on both sides of the second structural member 120. In other embodiments, the slide groove 111 may also be provided close to the middle of the second structural member 120.

[0103] This application embodiment also provides another structural component 100 and another moving component 200. As shown in Figures 16 and 19, the structural component 100 is in a first state. As shown in Figures 17, 18 and 20, the structural component 100 is in a second state.

[0104] In the above embodiments, referring to Figures 21 and 22, the moving component 200 includes a rotating component 220 and a mating component 230, with the rotating component 220 connected to the mating component 230. This application embodiment does not limit the number of rotating components 220 and mating components 230.

[0105] In this embodiment, the rotating member 220 is rotatably mounted on the second structural member 120, and the mating member 230 is mounted on the first structural member 110. In other embodiments, the rotating member 220 may also be mounted on the first structural member 110, and correspondingly, the mating member 230 is mounted on the second structural member 120. Here, "mounted" can be understood as "contained on," "connected to," "limited to," etc., and this embodiment does not limit the mounting method of the rotating member 220 on the second structural member 120.

[0106] The embodiments of this application do not limit the installation positions of the rotating member 220 and the mating member 230. In this embodiment, the rotating member 220 is disposed near the center of the second structural member 120, and the mating member 230 is disposed near the center of the first structural member 110. In other embodiments, the rotating member 220 may be disposed near either side of the second structural member 120, and the mating member 230 may be disposed near either side of the first structural member 110.

[0107] Referring to Figure 23, the mating member 230 has a first end and a second end. The first end of the mating member 230 is used to connect with the first structural member 110, and the second end of the mating member 230 is a free end. The direction from the first end of the mating member 230 to the second end of the mating member 230 is parallel to the first direction x. The mating member 230 can extend along a straight line, and based on this, the extension direction of the mating member 230 is parallel to the first direction x.

[0108] 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 causing the first structural member 110 to move relative to the second structural member 120 along the first direction x. Based on the above configuration, the user can switch the structural member 100 between the first state and the second state by operating the rotating member 220.

[0109] In the above embodiments, the distance between the rotating member 220 and the first end of the mating member 230 changes. As shown in FIG23, when the structural member 100 is in the first state, the distance between the rotating member 220 and the first end of the mating member 230 in the first direction x is a third distance l5; as shown in FIG24, when the structural member 100 is in the second state, the distance between the rotating member 220 and the first end of the mating member 230 in the first direction x is a fourth distance l6. The third distance l5 and the fourth distance l6 are different.

[0110] In an alternative embodiment, the third distance l5 may be less than the fourth distance l6. Referring to Figures 23 and 24, during the transition of the structural member 100 from the first state to the second state, the first end of the mating member 230 moves away from the rotating member 220.

[0111] In another alternative embodiment, the third distance l5 may be greater than the fourth distance l6.

[0112] In one optional embodiment, the rotating member 220 and the mating member 230 are connected by threads. One of the rotating member 220 and the mating member 230 has an internal thread, and the other has an external thread. In this embodiment, 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.

[0113] With the above settings, the user can adjust the size of the structural component 100 in the first direction x by operating the rotating component 220, so that the length of the watch strap 20 (as shown in Figure 1) fits the wrist circumference. When the rotating component 220 is stopped, there is thread friction between the rotating component 220 and the mating component 230. The rotating component 220 can limit the movement of the mating component 230 in the first direction x, so that the size of the structural component 100 in the first direction x remains unchanged, and the wearing comfort is maintained.

[0114] In another alternative embodiment, the rotating member 220 and the mating member 230 are engaged. For example, the rotating member 220 may include a gear, and the mating member 230 may include a rack.

[0115] Referring again to Figures 21 and 22, in one optional embodiment, the second structural member 120 includes a cover plate 121 and a base plate 122 connected to each other. This application embodiment does not limit the connection method of the cover plate 121 and the base plate 122. In some implementations, the cover plate 121 and the base plate 122 are detachably connected. For example, the cover plate 121 and the base plate 122 are connected by bolts 128; or, the cover plate 121 and the base plate 122 are magnetically connected; or, the cover plate 121 and the base plate 122 are connected by snap-fit. In other implementations, the cover plate 121 and the base plate 122 are non-detachably connected. For example, the cover plate 121 and the base plate 122 are riveted; or, the cover plate 121 and the base plate 122 are adhesively bonded.

[0116] When worn, at least one of the base plate 122 and the cover plate 121 can be in contact with the skin. For example, the base plate 122 can be in contact with the skin. Based on the above structure, referring to Figure 22, a bolt 128 can be provided on the base plate 122, thereby concealing the bolt 128 between the base 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.

[0117] The cover plate 121 and the base plate 122 together enclose a receiving cavity 123 (refer to Figure 11). At least one of the cover plate 121 and the base plate 122 has a first opening 124 communicating with the receiving cavity 123. For example, there is one first opening 124, which is located on one of the cover plate 121 and the base plate 122. Alternatively, both the cover plate 121 and the base plate 122 have first openings 124, with the first opening 124 on the cover plate 121 and the first opening 124 on the base plate 122 being arranged opposite to each other. This application embodiment does not limit the shape, size, or number of the first openings 124.

[0118] A portion of the rotating member 220 is located within the receiving cavity 123, and another portion of the rotating member 220 extends out of the receiving cavity 123 through the first opening 124 to facilitate user operation. The edge of the first opening 124 can abut against the rotating member 220 to restrict the movement of the rotating member 220 along the first direction x, thereby mounting the rotating member 220 onto the second structural member 120.

[0119] In some implementations, the rotating part 220 may be provided with knurling to facilitate user operation.

[0120] Referring to Figures 21 and 22, in an optional embodiment, the first structural member 110 has a limiting protrusion 116, and the second structural member 120 has a limiting groove 127, with the limiting protrusion 116 located within the limiting groove 127. When the first structural member 110 moves relative to the second structural member 120, the limiting protrusion 116 moves within the limiting groove 127. The limiting groove 127 has a first limiting surface 1271 and a second limiting surface 1272, which are disposed opposite to each other along a 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.

[0121] As shown in Figure 23, when the structural component 100 is in the first state, the limiting protrusion 116 is in contact with the first limiting surface 1271; referring to Figures 23 and 24, when the structural component 100 transitions 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 shown in Figure 24, when the structural component 100 is in the second state, the limiting protrusion 116 is in contact with the second limiting surface 1272.

[0122] In the above embodiments, the second limiting surface 1272 may be closer to the first end of the first belt body 300 (refer to Figure 3) relative to the first limiting surface 1271. Alternatively, the first limiting surface 1271 may be closer to the first end of the first belt body 300 relative to the second limiting surface 1272.

[0123] In another alternative embodiment, the limiting groove 127 may be provided on the first structural member 110, and the limiting protrusion 116 may be provided on the second structural member 120.
