Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to an adjustable component, a locking component, a strap component, a wristband, and a wearable device. Background Technology

[0002] With the rapid development and widespread adoption of wearable devices such as smartwatches and smart bracelets, users have higher demands for the comfort of wearing these devices. When wearing a smartwatch, users typically need to adjust the strap length to match the thickness of their wrist for optimal comfort. For example, in some current smartwatches, the strap includes multiple buckles spaced along its length. Users can connect the buckle to one of these buckles to achieve the desired length. However, the spacing between adjacent buckles prevents precise adjustment, resulting in a strap that is either too tight or too loose.

[0003] Currently, fine-tuning can be achieved by configuring adjustable components. However, in the current adjustable components, there is a large gap between the adjustable component itself or between the adjustable component and the strap body, which affects the wearing comfort and the continuity of the appearance. Utility Model Content

[0004] This invention provides an adjustable component, a buckle component, a strap component, a wristband, and a wearable device that can achieve precise length adjustment and have good structural continuity.

[0005] In a first aspect, this utility model provides an adjustable component for use with a wristband. The adjustable component includes a first connector, a second connector, and an adjustment mechanism. The first connector and the second connector are slidably connected in a first direction, and the adjustment mechanism is connected to the first connector and the second connector to adjust the connection length of the first connector and the second connector in the first direction, thereby achieving fine adjustment of the wristband length.

[0006] Furthermore, the first connector has a groove extending along a first direction. The groove has a first inner wall, a second inner wall, and a third inner wall. The first and second inner walls are both parallel to the first direction and face each other. The third inner wall is located between the first and second inner walls and faces the first inner wall. At least a portion of the second connector is located within the groove. The second connector has a first side wall and a second side wall. Both the first and second side walls are parallel to the first direction and face away from each other. The first side wall slides against the first inner wall, and the second side wall slides against the second inner wall to achieve a sliding connection between the first connector and the second connector in the first direction.

[0007] The second connector also includes a first protrusion, one end of which is connected to the first sidewall. The third inner wall has a first limiting portion, which abuts against the first protrusion in a first direction to prevent the first connector and the second connector from separating. Specifically, one end of the first protrusion is connected to the first sidewall, and the third inner wall has the first limiting portion. That is, the first limiting portion is located inside the groove and not on its inner surface. Therefore, the wall thickness of the groove can be effectively reduced, facilitating a decrease in the gap between the first and second connectors and improving the continuity of the adjustable assembly.

[0008] In one example, the slide also has a fourth inner wall located between the second and third inner walls, with the third inner wall facing the second inner wall. The second connector also includes a second protrusion, one end of which is connected to the second side wall. The fourth inner wall has a second limiting portion for abutting against the second protrusion in a first direction. Specifically, the first end of the second protrusion is connected to the second side wall, and the fourth inner wall has the second limiting portion. That is, the second limiting portion is located inside the slide and not on its inner surface; therefore, the wall thickness of the slide can be effectively reduced, facilitating a decrease in the gap between the first and second connectors and improving the continuity of the adjustable assembly.

[0009] In one example, the cross-section of the first protrusion gradually decreases from the first sidewall to the third inner wall. This helps to reduce the volume of the first protrusion, decrease the space occupied by the first protrusion in the groove, and the first protrusion still has good structural strength.

[0010] In one example, the cross-section of the second protrusion gradually decreases from the second sidewall to the fourth inner wall. This helps to reduce the volume of the second protrusion, decrease the space occupied by the second protrusion in the groove, and the second protrusion still has good structural strength.

[0011] In one example, the first inner wall and the second inner wall are arranged facing each other in a second direction, which is perpendicular to the first direction. The slide groove also has a fifth inner wall and a sixth inner wall, both of which are parallel to the first direction and are arranged facing each other in a third direction, which is perpendicular to both the first and second directions. The second connector also has a third side wall and a fourth side wall, both of which are parallel to the first direction; the third side wall slides with the fifth inner wall, and the fourth side wall slides with the sixth inner wall. That is, the sliding engagement between the first inner wall and the first side wall, and the sliding engagement between the second inner wall and the second side wall, prevents wobbling between the first connector and the second connector in the second direction. The sliding engagement between the fifth inner wall and the third side wall, and the sliding engagement between the sixth inner wall and the fourth side wall, prevents wobbling between the first connector and the second connector in the third direction, thus ensuring the stability of the first connector and the second connector when sliding in the first direction.

[0012] In one example, at the open end of the chute, the chute includes a first outer wall parallel to a first direction, and a first inner wall disposed opposite to each other in a second direction. The distance between the first outer wall and the first inner wall in the first direction is less than or equal to 0.4 mm. This results in the chute having a smaller wall thickness at the open end, effectively improving the continuity between the first connector and the second connector.

[0013] In one example, the second connector further includes a connecting portion, wherein in the first direction, the first protrusion is located at one end of the second connector, and the connecting portion is located at the other end of the second connector. In a cross-section perpendicular to the first direction, the length of the connecting portion in the second direction is less than the length of the groove in the second direction. When the connecting portion is connected to the belt body, the belt body can wrap around the outer periphery of the connecting portion to prevent the connecting portion from being exposed. Furthermore, since the length of the connecting portion in the second direction is less than the length of the groove in the second direction in a cross-section perpendicular to the first direction, the outer peripheral surface of the belt body can extend into the groove, effectively reducing the gap between the belt body and the first connecting member (or the open end of the groove), which is beneficial to improving the continuity between the adjustable component and the belt body.

[0014] In one example, the adjusting mechanism includes a rotating wheel and a screw. A first connecting member has a first limiting surface and a second limiting surface, which are arranged facing each other and both perpendicular to a first direction. The rotating wheel is located between the first and second limiting surfaces and has a threaded hole extending along the first direction. A first end of the screw is fixedly connected to a second connecting member, and a second end of the screw passes through the threaded hole. The rotating wheel can be reasonably limited between the first and second limiting surfaces, allowing it to rotate while preventing movement or wobbling along the first direction, thus improving the accuracy and stability during adjustment.

[0015] When the wheel rotates, it drives the screw to generate displacement along the first direction, thereby adjusting the connection length of the first and second connecting members in the first direction. Furthermore, the wheel and screw themselves possess a self-locking effect; therefore, when the wheel is not rotating, the sliding position between the first and second connecting members is not affected by external forces, exhibiting good reliability and stability.

[0016] In one example, the rotating wheel has a first surface and a second surface, which are disposed opposite to each other in a first direction. The first surface is used to abut against a first limiting surface, and the second surface is used to abut against a second limiting surface. This design allows the rotating wheel to rotate while preventing it from moving or wobbling along the first direction, thus improving the accuracy and stability during adjustment.

[0017] Secondly, this utility model also provides another adjustable component, which includes a first connecting member, a second connecting member, and an adjustment mechanism. The adjustment mechanism is connected to the first and second connecting members and is used to adjust the connection length of the first and second connecting members in a first direction. The first connecting member has a groove extending along the first direction, the groove having a first inner wall and a second inner wall, both of which are parallel to the first direction and are arranged facing each other. At least a portion of the second connecting member is located within the groove, the second connecting member having a first side wall and a second side wall, both of which are parallel to the first direction and are arranged opposite to each other, the first side wall slidingly engaging with the first inner wall, and the second side wall slidingly engaging with the second inner wall. The first connecting member has a protrusion extending perpendicular to the first direction, and the second connecting member has a groove. Along the first direction, the protrusion is slidably disposed within the groove. The adjustment mechanism includes a wheel and a screw; the first connecting member has a first limiting surface and a second limiting surface, the first limiting surface and the second limiting surface being arranged facing each other in the first direction. The rotating wheel is located between the first limiting surface and the second limiting surface, and the rotating wheel has a threaded hole extending in the first direction. The first end of the screw is fixedly connected to the second connecting member, and the second end of the screw passes through the threaded hole.

[0018] In the example provided by this utility model, a sliding connection between the first connector and the second connector can be achieved through the sliding fit between the first inner wall and the first side wall, and the sliding fit between the second inner wall and the second side wall. The slidable protrusion within the groove further enhances the stability of the sliding between the first and second connectors. Furthermore, the adjustment mechanism includes a rotating wheel and a screw. When the rotating wheel rotates, it drives the screw to generate displacement along a first direction, thereby adjusting the connection length of the first and second connectors in the first direction. Additionally, the rotating wheel and screw themselves possess a self-locking effect; therefore, when the rotating wheel is not rotated, the sliding position between the first and second connectors is not affected by external forces, exhibiting good reliability and stability.

[0019] In one example, the groove has a first stop surface and a second stop surface, which are arranged facing each other in a first direction. The protrusion has a first mating surface and a second mating surface, which are arranged opposite to each other in the first direction. The first mating surface abuts against the first stop surface, and the second mating surface abuts against the second stop surface. That is, the groove can reasonably control the sliding distance of the protrusion in the first direction to prevent the first connector and the second connector from disengaging. In addition, since both the first stop surface and the second stop surface are located in the groove, it can also be considered that neither the first stop surface nor the second stop surface is provided on the inner surface of the groove. Therefore, the wall thickness of the slide can be effectively reduced, which facilitates reducing the gap between the first connector and the second connector and improves the continuity of the adjustable component. In one example, the roller has a first surface and a second surface, which are arranged opposite to each other in the first direction. The first surface abuts against the first limiting surface, and the second surface abuts against the second limiting surface. This method allows the wheel to be rotated, while also preventing the wheel from moving or wobbling in the first direction, thus improving the accuracy and stability of the adjustment.

[0020] Thirdly, this utility model also provides a locking assembly, including a locking buckle and any of the aforementioned adjustable components. The locking buckle can be connected to a first connecting member or a second connecting member in the adjustable assembly. By configuring the adjustable component in the locking assembly, fine-tuned length adjustment can be achieved, providing good adaptability.

[0021] Fourthly, this utility model also provides a belt assembly, including a belt body and the aforementioned adjustable component, wherein a first end of the belt body is connected to a first connector or a second connector. By configuring the adjustable component in the belt assembly, fine-tuned length adjustment can be achieved, resulting in good adaptability.

[0022] In one example, the first end of the belt can be connected to the second connector, and the first end of the belt can be located in a groove to reduce the gap between the belt and the first connector.

[0023] In one example, the outer peripheral surface of the first end of the belt can slide against the inner wall of the groove to reduce the gap between the belt and the inner wall of the groove, which can further reduce the gap between the belt and the first connector.

[0024] Fifthly, this utility model provides a wristband, including a strap body and the aforementioned buckle assembly. One end of the strap body is connected to a first connecting member, and the buckle is connected to a second connecting member. Alternatively, one end of the strap body is connected to the second connecting member, and the buckle is connected to the first connecting member. The buckle is used to connect to the strap body. By equipping the wristband with a buckle assembly, precise length adjustment can be achieved, resulting in good adaptability.

[0025] Sixthly, this utility model provides a wristband, including a buckle and the aforementioned strap assembly. One end of the strap body is connected to a first connecting member, and the buckle is connected to a second connecting member. Alternatively, one end of the strap body is connected to the second connecting member, and the buckle is connected to the first connecting member. The buckle is used to connect to the strap body. By equipping the wristband with a buckle assembly, precise length adjustment can be achieved, resulting in good adaptability.

[0026] Seventhly, this utility model provides a wristband, including the aforementioned buckle assembly and band body assembly, wherein the buckle is used to connect with the band body. By equipping the wristband with the buckle assembly, precise length adjustment can be achieved, resulting in good adaptability.

[0027] Eighthly, this utility model also provides a wearable device, including a device body and the aforementioned wristband, the wristband being connected to the device body. By equipping the wristband with a locking assembly, precise length adjustment can be achieved, resulting in good adaptability. Attached Figure Description

[0054] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in further detail below with reference to the accompanying drawings.

[0055] To facilitate understanding of the adjustable component provided in this utility model embodiment, its application scenarios are first introduced below. It should be noted that, in some of the following examples, spatial directions and coordinate systems are referenced for ease of understanding of the technical solution of this application. For example, the direction may include a first direction, a second direction, and a third direction. The first direction, the second direction, and the third direction are all perpendicular to each other. Corresponding to the spatial coordinate system, the first direction is aligned with the X-axis, the second direction with the Y-axis, and the third direction with the Z-axis.

[0056] The adjustable component provided in this embodiment can be applied to various types of strap structures such as wristbands and headbands, allowing users to wear wearable devices such as smartwatches, smart bracelets, and smart glasses through the strap structure.

[0057] For example, when the band structure is a wristband, the user can wear the wearable device on their wrist. To facilitate understanding of the technical solution of this utility model, the following will provide an exemplary description using the application of an adjustable component in the wristband of a smartwatch.

[0058] To facilitate understanding of the specific function and effect of the adjustable component, the general structure of the smartwatch 20 without the adjustable component will be described first as an example.

[0059] For example, such as Figure 1 As shown, a conventional smartwatch 20 is illustrated, which includes a wristband 10 and a watch body 21.

[0060] The watch body 21 may include a display screen or other display-functional device to enable the watch body 21 to display information. Alternatively, the watch body 21 may include a microphone or speaker to enable audio reception and playback. In one example, the watch body 21 may also include an antenna to enable signal communication. Alternatively, the watch body 21 may include a blood pressure monitor to enable health monitoring. The watch body 21 can adopt various commonly used types, and this invention does not limit the specific structure or functions of the watch body 21.

[0061] In a typical example, the wristband 10 includes a first band 11, a second band 12, and a clasp 13. One end of the first band 11 is connected to the watch body 21, and the other end is connected to the clasp 13. One end of the second band 12 is connected to the watch body 21, and the other end is connected to the clasp 13. That is, the watch body 21 is connected to one end of the first band 11 and the second band 12, and the clasp 13 is connected to the other end of the first band 11 and the second band 12. The specific connection methods between the first band 11 and the watch body 21 and the clasp 13, and the specific connection methods between the second band 12 and the watch body 21 and the clasp 13, can adopt currently well-known types and will not be elaborated here.

[0062] exist Figure 1 In the example provided, the buckle 13 is specifically a butterfly buckle or folding buckle. Buckle 13 is a commonly used structural type. Simply put, buckle 13 includes a first folding arm 131, a second folding arm 132, and a buckle body 133. One end of the first folding arm 131 is rotatably connected to the first strap body 11, and the other end is rotatably connected to the buckle body 133. One end of the second folding arm 132 is rotatably connected to the second strap body 12, and the other end is rotatably connected to the buckle body 133. Figure 1 In the middle, the clasp 13 is in the unfolded state, giving the entire wristband 10 a larger connection length, so that the user can pass their hand through the space enclosed by the wristband 10 and the watch body 21, thereby moving the smartwatch 20 to the wrist. Then, the first folding arm 131 and the second folding arm 132 can be folded towards the buckle 133 and locked, thereby reducing the space enclosed by the wristband 10 and the watch body 21, so that the length enclosed by the wristband 10 and the watch body 21 matches the thickness of the wrist (i.e., wrist circumference), and finally the smartwatch 20 can be worn on the wrist.

[0063] In the current design, the first band 11 and the second band 12 are typically composed of multiple sequentially connected links 110, giving them a fixed length. In practical applications, different users have significantly different wrist circumferences. To accommodate different wrist circumferences, the number of links 110 in the first band 11 or the second band 12 is usually increased or decreased. However, a single link 110 has a distinct length, preventing precise length adjustment. Users may experience discomfort due to wearing the watch too tightly or too loosely, compromising comfort. Furthermore, when some watches 21 contain devices for blood pressure monitoring, the tightness of the fit is crucial; wearing the watch too tightly or too loosely can lead to inaccurate monitoring results.

[0064] Or, such as Figure 2 As shown, in another conventional solution provided by this utility model embodiment, the wristband 10 can also be of other structural types.

[0065] In simple terms, the wristband 10 includes a first band body 11, a second band body 12, and a clasp 13. One end of the first band body 11 is connected to the watch body 21, and the other end is connected to the clasp 13. One end of the second band body 12 is connected to the watch body 21, and the other end is connected to the clasp 13.

[0066] The clasp 13 includes a clasp frame 134 and a latch 135. The second strap 12 includes multiple buckle holes 121 spaced apart along its length. In actual use, the free end of the second strap 12 can be passed through the frame-shaped space in the clasp frame 134, and the latch 135 can be threaded into a desired buckle hole 121 to wear the smartwatch 20 on the wrist. In actual use, the latch 135 can be selectively threaded into a specific buckle hole 121 to make the wristband 10 and the watch body 21 form the desired length, thereby achieving an effective fit with the wrist circumference.

[0067] However, in Figure 2 In the example provided, there is a significant distance between two adjacent buckle holes 121, making fine-tuning of the length impossible. Therefore, users may experience the product being too tight or too loose after wearing it.

[0068] It should be noted that in the above example, with Figure 1 and Figure 2 The wristband 10 shown is for illustrative purposes only. Other types of wristbands 10 also suffer from the problem described above of not being able to achieve fine, stepless adjustment, which will not be illustrated here.

[0069] Therefore, this embodiment of the invention provides an adjustable component for use in a wristband 10, which can achieve stepless adjustment of the connection length. Thus, when the wristband 10 is equipped with this adjustable component, the wristband 10 containing the adjustable component can have the function of stepless length adjustment.

[0070] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0071] Please see Figure 3 and Figure 4 , Figure 3 This is a simplified structural diagram of the adjustable component 30 in a certain state. Figure 4 This is a simplified structural diagram of the adjustable component 30 in another state. In one example provided by this utility model, the adjustable component 30 includes a first connector 31, a second connector 32, and an adjustment mechanism. Figure 3 and Figure 4 (Not shown in the image). In some embodiments, the second connector may also be referred to as a telescopic link. The first connector 31 and the second connector 32 are slidably connected in a first direction. The adjusting mechanism 33 is connected to the first connector 31 and the second connector 32 and is used to adjust the connection length of the first connector 31 and the second connector 32 in the first direction, thereby achieving stepless adjustment of the connection length.

[0072] The connection length of the first connector 31 and the second connector 32 in the first direction refers to the length or distance between the connecting portions of the first connector 31 and the second connector 32 in the first direction. For example, in Figure 3 and Figure 4In the example provided, the connection length of the first connector 31 and the second connector 32 in the first direction refers to the distance between the connecting portion 31111 of the first connector 31 and the connecting portion 32111 of the second connector 32 in the first direction. In one example, the connecting portion 31111 can be used to connect with a structure such as a strap, watch body, or clasp. The connecting portion 32111 can be used to connect with components such as a clasp, strap, or watch body. In other words, the adjustable component 30 is used to connect two components (such as the first component and the second component). It is understood that the components (such as the first component and the second component) can be a watch strap or a watch clasp, for example, both the first component and the second component can be watch straps. Or the first component is a watch strap, and the second component is a watch clasp. Or conversely, the first component is a watch clasp, and the second component is a watch strap. Wherein, the connecting portion 31111 is used to connect with the first component, and the connecting portion 32111 is used to connect with the second component, the connection length of the first connector 31 and the second connector 32 in the first direction can also be regarded as the distance between the first component and the second component. When the connection length of the first connector 31 and the second connector 32 changes in the first direction, the distance between the first component and the second component also changes accordingly.

[0073] In the example provided by this utility model, the first connecting member 31 and the second connecting member 32 are slidably connected in the first direction, so that within the sliding stroke, the first connecting member 31 and the second connecting member 32 can be in any relative sliding position, thereby realizing stepless adjustment of the connection length of the first connecting member 31 and the second connecting member 32 in the first direction. It is understood that the connection length of the first connecting member 31 and the second connecting member 32 in the first direction in the embodiments of this application can be referred to the description here, and will not be repeated hereafter.

[0074] exist Figure 3 In the example provided, the first connector 31 and the second connector 32 are in a first relative sliding position. At this time, the distance between the connecting part 31111 and the connecting part 32111 is L1, and the connection length of the first connector 31 and the second connector 32 in the first direction is small.

[0075] exist Figure 4 In the example provided, the first connector 31 and the second connector 32 are in the second relative sliding position. At this time, the distance between the connecting part 31111 and the connecting part 32111 is L2, and the connection length of the first connector 31 and the second connector 32 in the first direction is large.

[0076] like Figure 6As shown, when the adjustable component 30 is applied to the wristband 10 of the smartwatch 20, the length of the entire wristband 10 can be changed by altering the connection length of the first connector 31 and the second connector 32 in the first direction, thereby achieving stepless adjustment of the wristband 10 length. It should be noted that in... Figure 6 In the example provided, the adjustable component 30 is connected between the buckle 13 and the first strap 11. In other examples, the adjustable component 30 can be applied to various different positions within the wristband 10. Alternatively, the adjustable component 30 can also be connected between the first strap 11 and the watch body 21, or between the second strap 12 and the watch body 21. Alternatively, the adjustable component 30 can also be disposed within the strap body. For example, the first strap 11 can be divided into two segments, and the adjustable component 30 can be connected between the two segments.

[0077] Alternatively, in some examples, the wristband 10 may not include the buckle 13. For example, without the buckle 13, one end of the adjustable component 30 may be connected to the first strap body 11, and the other end may be connected to the second strap body 12. That is, the adjustable component 30 may also be applied to other types of wristbands 10.

[0078] The first connector 31 and the second connector 32 can be slidably connected in the first direction and have their positions limited by a structure of grooves and protrusions (or protrusions).

[0079] For example, such as Figure 5 As shown, in one example provided by this utility model, the first connecting member 31 includes a base 311 and a cover 312. The base 311 and the cover 312 are connected, and the base 311 and the cover 312 together form a groove 310 with one end open. Specifically, the base 311 has a groove 3110, and the cover 312 has a groove 3120. After the base 311 and the cover 312 are engaged, the grooves 3110 and 3120 face each other, so that the grooves 3110 and 3120 together form one end (e.g., Figure 5 A groove 310 with an opening in the X direction. At least a portion of the second connector 32 is located within the groove 310 and slides in cooperation with the groove 310.

[0080] For details, please refer to the following: Figure 3 Figure 4 and Figure 5 .exist Figure 3 and Figure 4 In order to clearly show the structure of the adjustable component 30, the cover 312 is omitted.

[0081] The second connector 32 has a protrusion 321, which includes a first protrusion 3211 and a second protrusion 3212. The protrusion 321 is located in the groove 310 and slides in cooperation with the groove 310, thereby realizing the sliding connection between the first connector 31 and the second connector 32 and preventing the first connector 31 and the second connector 32 from shaking in a direction perpendicular to the first direction (X-axis direction).

[0082] For ease of understanding, a spatial coordinate system is introduced in some of the accompanying drawings, in which the X-axis is consistent with the first direction mentioned above, and the Y-axis and Z-axis are both perpendicular to the X-axis, and the Y-axis is perpendicular to the Z-axis.

[0083] like Figure 3 and Figure 4 As shown, the groove 3110 (or slide 310) has two inner walls, namely a first inner wall 3110a and a second inner wall 3110b. Both the first inner wall 3110a and the second inner wall 3110b are parallel to the X-axis and perpendicular to the Y-axis, and are arranged facing each other in the Y-axis direction. In one possible embodiment, the first inner wall 3110a and the second inner wall 3110b are parallel to each other. The first protrusion 3211 has a first side wall 3211a, and the second protrusion 3212 has a second side wall 3212a. Both the first side wall 3211a and the second side wall 3212a are parallel to the X-axis and perpendicular to the Y-axis. Furthermore, the first side wall 3211a and the second side wall 3212a are arranged opposite to each other in the Y-axis direction. In one possible embodiment, the first side wall 3211a and the second side wall 3212a are parallel to each other. The first sidewall 3211a is in sliding engagement with the first inner wall 3110a, and the second sidewall 3212a is in sliding engagement with the second inner wall 3110b. The sliding engagement of the first sidewall 3211a with the first inner wall 3110a and the second sidewall 3212a with the second inner wall 3110b can prevent the second connecting member 32 from displacing in the Y-axis direction and in the opposite direction of the Y-axis within the groove 310.

[0084] The parallelism of the first inner wall 3110a and the second inner wall 3110b to the X-axis includes both strict parallelism and approximate parallelism. For example, a small angle may exist between the first inner wall 3110a and the second inner wall 3110b; this angle can be any value less than or equal to 2°. In other words, the parallelism of the first inner wall 3110a to the X-axis refers to approximate parallelism, and the parallelism of the second inner wall 3110b to the X-axis refers to approximate parallelism. Furthermore, the facing arrangement of the first inner wall 3110a and the second inner wall 3110b in the Y-axis direction includes both strict facing arrangement and approximate facing arrangement. In other words, the first inner wall 3110a is approximately perpendicular to the Y-axis, and the second inner wall 3110b is approximately perpendicular to the Y-axis.

[0085] Furthermore, to prevent the first connector 31 and the second connector 32 from detaching, the groove 3110 has a second stop surface 3110e. One end of the second stop surface 3110e is connected to the first inner wall 3110a, and the other end extends towards the second inner wall 3110b. During the sliding of the first protrusion 3211 along the first direction, the sliding stops when the side wall 3211c of the first protrusion 3211 abuts against the second stop surface 3110e, thus preventing the first connector 31 and the second connector 32 from detaching. However, since one end of the second stop surface 3110e is connected to the first inner wall 3110a, and the other end extends towards the second inner wall 3110b, the wall thickness H1 of the sliding cavity 310 at the port is relatively large. This results in a large gap between the first connector 31 and the second connector 32, meaning that the dimensions of the adjustable component in the Y direction differ significantly along the X direction. This affects the continuity of the adjustable component 30's appearance and leads to a poor user experience.

[0086] Therefore, this utility model embodiment provides a way to effectively reduce the wall thickness of the groove 310 through some structural designs.

[0087] like Figure 7 , Figure 8 and Figure 9 As shown, in one example provided by this utility model, the first connector 31 includes a base 311 and a cover 312. The base 311 and the cover 312 are connected, and the base 311 and the cover 312 together form a groove 310 with one end open.

[0088] In some embodiments, the base may also be called the bottom cover, and the cover may also be called the upper shell; or, the base may also be called the upper shell, and the cover may also be called the bottom cover. This application does not limit this.

[0089] For details, please refer to the following: Figure 7 Figure 9 and Figure 10 .in, Figure 10 This is a three-dimensional structural diagram of the cover 312 from another perspective. The base 311 has a groove 3110, and the cover 312 has a groove 3120. After the base 311 and the cover 312 are engaged, the grooves 3110 and 3120 face each other, so that the grooves 3110 and 3120 together form one end (e.g., Figure 7A groove 310 with an opening in the X direction is provided. At least a portion of the second connecting member 32 is located within the groove 310 and slides within it. In one example, the base 311 and the cover 312 can be fixedly connected by screws, rivets, or other connecting members. For example, when the base 311 and the cover 312 are fixedly connected by screws, threaded holes for connecting the screws can be provided in both the base 311 and the cover 312. Alternatively, the base 311 and the cover 312 can also be fixedly connected by bonding, welding, or other methods. That is, the base 311 and the cover 312 can be fixedly connected in a variety of different ways.

[0090] like Figure 9 and Figure 10 As shown, the slide 310 has three inner walls: a first inner wall 3110a, a second inner wall 3110b, and a third inner wall 3110f. The first and second inner walls 3110a and 3110b are both parallel to the X-axis and are arranged facing each other in the Y-axis direction. In one possible embodiment, the first and second inner walls 3110a and 3110b are parallel to each other. The third inner wall 3110f is located between the first and second inner walls 3110a and 3110b, and is arranged facing the first inner wall 3110a. In another possible embodiment, the first, second, and third inner walls 3110a and 3110f are parallel to each other.

[0091] In one possible implementation, a portion of the first inner wall 3110a is located in the base 311, and another portion is located in the cover 312. After the base 311 and the cover 312 are engaged, the first inner wall 3110a located in the base 311 is connected to the first inner wall 3110a located in the cover 312 to form a complete first inner wall 3110a. Correspondingly, a portion of the second inner wall 3110b is located in the base 311, and another portion is located in the cover 312. After the base 311 and the cover 312 are engaged, the second inner wall 3110b located in the base 311 is connected to the second inner wall 3110b located in the cover 312 to form a complete second inner wall 3110b. Correspondingly, a portion of the third inner wall 3110f is located in the base 311, and another portion is located in the cover 312. After the base 311 and the cover 312 are engaged, the third inner wall 3110f located in the base 311 is connected to the third inner wall 3110f located in the cover 312 to form a complete third inner wall 3110f.

[0092] The matching relationship between the second connector 32 and the base 311 and the matching relationship between the second connector 32 and the cover 312 are the same. For ease of understanding, the matching relationship between the second connector 32 and the base 311 will be used as an example for illustration below.

[0093] like Figure 11 and Figure 12 As shown, the second connector 32 has a first sidewall 3211a and a second sidewall 3212a. Both the first sidewall 3211a and the second sidewall 3212a are parallel to the X-axis, and are arranged opposite to each other. In one possible embodiment, the first sidewall 3211a and the second sidewall 3212a are parallel to each other, that is, the orientations of the first sidewall 3211a and the second sidewall 3212a are opposite. The parallelism of the first sidewall 3211a to the X-axis includes both strict parallelism and approximate parallelism. Similarly, the parallelism of the second sidewall 3212a to the X-axis includes both strict parallelism and approximate parallelism. Furthermore, the opposite arrangement of the first sidewall 3211a and the second sidewall 3212a includes both strict opposite arrangement and approximate opposite arrangement. In other words, the first sidewall 3211a is approximately perpendicular to the Y-axis, and the second sidewall 3212a is approximately perpendicular to the Y-axis.

[0094] The first sidewall 3211a is in sliding engagement with the first inner wall 3110a, and the second sidewall 3212a is in sliding engagement with the second inner wall 3110b. The sliding engagement of the first sidewall 3211a with the first inner wall 3110a and the second sidewall 3212a with the second inner wall 3110b can prevent the second connecting member 32 from displacing in the Y-axis direction and in the opposite direction of the Y-axis within the groove 310.

[0095] Additionally, the second connector 32 includes a first protrusion 3211, one end of which is connected to the first sidewall 3211a. The third inner wall 3110f has a first limiting portion 31101f, which abuts against the first protrusion 3211 in a first direction to prevent the first connector 31 from disengaging from the second connector 32. Specifically, the first limiting portion 31101f abutting against the first protrusion 3211 in the first direction includes direct or indirect abutment between the first limiting portion 31101f and the first protrusion 3211. For example, when the first limiting part 31101f and the first protrusion 3211 indirectly abut against each other, other structural members can be provided between the first limiting part 31101f and the first protrusion 3211. The structural member can be fixed to the first limiting part 31101f, or the structural member can be fixed to the first protrusion 3211, or structural members can be provided in both the first limiting part 31101f and the first protrusion 3211.

[0096] In the example of this application, one end of the first protrusion 3211 is connected to the first sidewall 3211a, and the third inner wall 3110f has a first limiting portion 31101f. That is, the first limiting portion 31101f is located inside the groove 310 and is not provided on the inner surface of the groove 310. Therefore, the wall thickness of the groove 310 can be effectively reduced, which facilitates reducing the gap between the first connector 31 and the second connector 32, thereby improving the continuity of the adjustable assembly 30. Here, the inner surface of the groove 310 refers to the surface (or inner wall) used to form the inner contour of the groove 310. For example, the first inner wall 3110a, the second inner wall 3110b, the sidewall 3110c, and the sidewall 3120a of the groove 310 can be collectively referred to as the inner surface of the groove 310.

[0097] For example, in Figure 11 The example provided shows a wall thickness H2 of the slide 310. Since no second stop surface 3110e is provided at the first inner wall 3110a of the slide 310, the wall thickness H2 can be less than [the required thickness]. Figure 4 The wall thickness H1 is shown. For example, in one example, the wall thickness H2 can be less than or equal to 0.4 mm. In one possible implementation, the groove 310 includes an inner surface and an outer surface, and the wall thickness H2 can refer to the distance between the inner and outer surfaces of the groove 310 in the Y-axis direction. In one possible implementation, the inner surface may include a first inner wall 3110a, and the outer surface may include a first outer wall 31100a, and the first outer wall 31100a and the first inner wall 3110a are disposed opposite to each other in the Y-axis direction. In one possible implementation, the first outer wall 31100a and the first inner wall 3110a are parallel to each other. In this case, the wall thickness H2 can be understood as the distance between the first outer wall 31100a and the first inner wall 3110a in the Y-axis direction. Similarly, in one possible implementation, the inner surface may include a second inner wall 3110b, and the outer surface 31100 may include a second outer wall 31100b, with the second outer wall 31100b and the second inner wall 3110b disposed opposite to each other in the Y-axis direction. In another possible implementation, the second outer wall 31100b and the second inner wall 3110b are parallel to each other. In this case, the wall thickness H3 can be understood as the distance between the second outer wall 3110b and the second inner wall 3110b in the Y-axis direction. In one example, H2 and H3 may be the same or different.

[0098] It should be noted that, as Figure 9 and Figure 10As shown, the first limiting part 31101f comprises two substantially identical parts. One part of the first limiting part 31101f is located in the base 311, and the other part is located in the cover 312. After the base 311 and the cover 312 are engaged, the first limiting part 31101f located in the base 311 is connected to the first limiting part 31101f located in the cover 312 to form the complete first limiting part 31101f.

[0099] In one example, the groove 310 further includes a fourth inner wall 3110g, and the second connector 32 further includes a second protrusion 3212, one end of which is connected to the second side wall 3212a. The fourth inner wall 3110g has a second limiting portion 31101g, which abuts against the second protrusion 3212 in a first direction to prevent the first connector 31 from disengaging from the second connector 32. Specifically, the second limiting portion 31101g abutting against the second protrusion 3212 in the first direction includes direct or indirect abutment between the second limiting portion 31101g and the second protrusion 3212. For example, when the second limiting part 31101g and the second protrusion 3212 indirectly abut against each other, other structural members can be provided between the second limiting part 31101g and the second protrusion 3212. The structural members can fix the second limiting part 31101g, or the structural members can be fixed to the second protrusion 3212, or structural members can be provided for both the second limiting part 31101g and the second protrusion 3212.

[0100] In the example of the application, one end of the second protrusion 3212 is connected to the second sidewall 3212a, and the fourth inner wall 3110g has a second limiting portion 31101g. That is, the second limiting portion 31101g is located inside the slide groove 310, and is not provided on the inner surface of the slide groove 310. Therefore, the wall thickness of the slide groove 310 can be effectively reduced, which facilitates reducing the gap between the first connector 31 and the second connector 32, thereby improving the continuity of the adjustable assembly 30.

[0101] In this design, a portion of the fourth inner wall 3110g is located in the base 311, and the other portion is located in the cover 312. After the base 311 and the cover 312 are engaged, the fourth inner wall 3110g located in the base 311 and the fourth inner wall 3110g located in the cover 312 are connected to form a complete fourth inner wall 3110g. Additionally, the second limiting portion 31101g comprises two substantially identical portions. A portion of the second limiting portion 31101g is located in the base 311, and the other portion is located in the cover 312. After the base 311 and the cover 312 are engaged, the second limiting portion 31101g located in the base 311 and the second limiting portion 31101g located in the cover 312 are connected to form a complete second limiting portion 31101g.

[0102] It should be noted that the example provided in this application is exemplified by the fact that both the base 311 and the cover 312 have a first inner wall 3110a, a second inner wall 3110b, a third inner wall 3110f, a fourth inner wall 3110g, a first limiting portion 31101f, and a second limiting portion 31101g. In other examples, the first inner wall 3110a, the second inner wall 3110b, the third inner wall 3110f, the fourth inner wall 3110g, the first limiting portion 31101f, or the second limiting portion 31101g may only be provided in the base 311. Alternatively, the first inner wall 3110a, the second inner wall 3110b, the third inner wall 3110f, the fourth inner wall 3110g, the first limiting portion 31101f, or the second limiting portion 31101g may only be provided in the cover 312.

[0103] In addition, such as Figure 9 and Figure 13 As shown. Figure 13 This is a simplified cross-sectional view of the adjustable mechanism 30 in the direction perpendicular to the X-axis. The groove 3110 (or slide 310) also has a fifth inner wall 3110c and a sixth inner wall 3120a. Both the fifth inner wall 3110c and the sixth inner wall 3120a are parallel to the X-axis. The fifth inner wall 3110c and the sixth inner wall 3120a are arranged facing each other in the Z-axis direction. In one possible embodiment, the fifth inner wall 3110c and the sixth inner wall 3120a are parallel to each other. The second connector 32 has a third side wall 321a and a fourth side wall 321b, both of which are parallel to the first direction. The third side wall 321a is slidably engaged with the fifth inner wall 3110c, and the fourth side wall 321b is slidably engaged with the sixth inner wall 3120a to prevent the second connector 32 from displacing in the slide 310 in the Z-axis direction and the opposite direction of the Z-axis.

[0104] That is, by limiting the position in the Y-axis and Z-axis directions, the first connector 31 and the second connector 32 can only slide in the direction parallel to the X-axis.

[0105] The sliding fit between the first sidewall 3211a and the first inner wall 3110a refers to a relative sliding relationship between them. For example, the first sidewall 3211a and the first inner wall 3110a can be in direct contact, or they can be indirect contact. For example, when the first sidewall 3211a and the first inner wall 3110a are in indirect contact, other structural components can be provided between the first sidewall 3211a and the first inner wall 3110a. These structural components can be fixed to the first sidewall 3211a, or they can be fixed to the first inner wall 3110a, or structural components can be provided on both the first sidewall 3211a and the first inner wall 3110a. Alternatively, in one example, the first sidewall 3211a and the first inner wall 3110a can also be provided with sliding fit structures such as protrusions and grooves. In summary, the first sidewall 3211a and the first inner wall 3110a can achieve a sliding fit in a variety of different ways so that relative sliding can occur between them.

[0106] Furthermore, the specific implementation methods of the sliding fit between the second sidewall 3212a and the second inner wall 3110b, the sliding fit between the third sidewall 321a and the fifth inner wall 3110c, and the sliding fit between the fourth sidewall 321b and the sixth inner wall 3120a can be the same or similar to the above-mentioned sliding fit between the first sidewall 3211a and the first inner wall 3110a, and will not be elaborated here.

[0107] It should be noted that, in Figures 7 to 12 The example provided shows only one possible example of a sliding connection between the first connector 31 and the second connector 32 along the X-axis. Other examples may also achieve a sliding connection by providing other structures or surfaces in the first connector 31 and the second connector 32, which will not be elaborated here.

[0108] In addition, in order to reasonably limit the maximum displacement stroke between the first connector 31 and the second connector 32, corresponding stop surfaces are also provided in the first connector 31 and the second connector 32.

[0109] Specifically, such as Figure 9 As shown, the groove 3110 has a first stop surface 3110d and a second stop surface 3110e, which are arranged facing each other in the X-axis direction. In one possible embodiment, the first stop surface 3110d and the second stop surface 3110e are parallel to each other. A first protrusion 3211 is located between the first stop surface 3110d and the second stop surface 3110e, thereby limiting the maximum sliding distance of the protrusion 321 in the X-axis direction. In one possible embodiment, the first stop surface 3110d and the second stop surface 3110e are parallel.

[0110] The first protrusion 3211 has sidewalls 3211b and 3211c that are opposite to each other in the X direction. In one possible embodiment, sidewalls 3211b and 3211c are parallel to each other. A first stop surface 3110d and sidewall 3211b are disposed facing each other, and a second stop surface 3110e and sidewall 3211c are disposed facing each other. In one possible embodiment, the first stop surface 3110d and sidewall 3211b are parallel, and / or, the second stop surface 3110e and sidewall 3211c are parallel.

[0111] like Figure 9 and Figure 11 As shown, when the protrusion 321 slides to one end of the groove 3110, the first stop surface 3110d and the side wall 3211b abut against each other. At this time, the connection length of the first connector 31 and the second connector 32 in the X-axis direction is the shortest.

[0112] like Figure 9 and Figure 12 As shown, when the protrusion 321 slides to the other end of the groove 3110, the second stop surface 3110e and the side wall 3211c abut against each other to prevent the protrusion 321 from sliding out of the groove 3110. At this time, the connection length of the first connector 31 and the second connector 32 in the X-axis direction is the longest.

[0113] The second protrusion 3212 of the protrusion 321 has the same structure as the first protrusion 3211, and the first connector 31 also has a stop surface that is adapted to the second protrusion 3212, which will not be described in detail here.

[0114] It should be noted that the example provided in this utility model is exemplified by the first connector 31 comprising a base 311 and a cover 312. The inclusion of both the base 311 and the cover 312 in the first connector 31 effectively improves its manufacturing convenience and facilitates the assembly of the first connector 31 and the second connector 32. The base 311 and the cover 312 can be fixedly connected by screws or other fasteners, or by welding; this utility model does not impose any limitations on this. In other examples, the first connector 31 may also be composed of one or more components. Correspondingly, the second connector 32 may also be composed of multiple components, which will not be elaborated upon here.

[0115] In addition, Figures 7 to 12In the example provided, both the first protrusion 3211 and the second protrusion 3212 are hook-shaped structures. For example, the sidewall 3211c is inclined or forms an angle with both the X-axis and the Y-axis. Additionally, the first connector 31 is also equipped with hook-shaped structures adapted to the first protrusion 3211 and the second protrusion 3212 to achieve effective stopping of the first connector 31 and the second connector 32 in the X-axis direction. In other examples, the first protrusion 3211 and the second protrusion 3212 of the second connector 32 can also be of other structural types. Correspondingly, the hook-shaped structures in the first connector 31 adapted to the first protrusion 3211 and the second protrusion 3212 can also be of other structural types.

[0116] For example, such as Figure 14 As shown, an exploded structural diagram of another adjustable component 30 is illustrated.

[0117] It should be noted first that, in Figure 14 and Figure 9 Compared to the adjustable component 30 shown, the shapes of the protrusions 321 and the shapes that adapt to the protrusions 321 differ, while other structures are largely the same or similar. That is to say, Figure 14 Some structures of the adjustable component 30 shown can be referred to Figure 9 The adjustable component 30 shown is understood in this context. In summary, the first connector 31 includes a base 311 and a cover 312. The base 311 and the cover 312 together form a groove 310 open at one end. At least a portion of the second connector 32 is located within the groove 310 and slides within it.

[0118] The groove 3110 has two inner walls, namely a first inner wall 3110a and a second inner wall 3110b. The protrusion 321 includes two parts, namely a first protrusion 3211 and a second protrusion 3212. The first protrusion 3211 has a first side wall 3211a, and the second protrusion 3212 has a second side wall 3212a. By slidingly engaging the first side wall 3211a with the first inner wall 3110a and the second side wall 3212a with the second inner wall 3110b, displacement of the protrusion 321 in the groove 310 along the Y-axis and in the opposite direction of the Y-axis can be prevented.

[0119] Additionally, the groove 3110 has a sidewall 3110c, and the groove 3120 has a sidewall 3120a facing the sidewall 3110c. Both sidewalls 3110c and 3120a are perpendicular to the Z-axis. After the protrusion 321 is located within the groove 310, its two surfaces, which are opposite to each other along the Z-axis, slide in engagement with the sidewalls 3110c and 3120a respectively, to prevent the protrusion 321 from displacing within the groove 310 in the Z-axis direction and in the opposite direction.

[0120] That is, by limiting the position in the Y-axis and Z-axis directions, the first connector 31 and the second connector 32 can only slide in the direction parallel to the X-axis.

[0121] In addition, such as Figure 14 , Figure 15 and Figure 16 As shown, in another example provided by this utility model, the first sidewall 3211a of the groove 3110 is slidably engaged with the first inner wall 3110a of the first protrusion 3211, and the sidewall 3212a of the groove 3110 is slidably engaged with the second inner wall 3110b of the second protrusion 3212, so as to prevent displacement or shaking in the Y-axis direction between the base 311 of the first connector 31 and the second connector 32.

[0122] In addition, other sliding fit structures are provided between the first connector 31 and the second connector 32 to further prevent displacement or wobbling in the Y-axis direction between the bases 311 of the first connector 31 and the second connector 32.

[0123] Specifically, the first connector 31 has two protrusions extending along the Z-axis direction in the groove 3110, namely protrusion 3111 and protrusion 3112. The second connector 32 has two grooves extending along the Z-axis direction, namely groove 3213 and groove 3214.

[0124] like Figure 14 and Figure 15As shown, after the first connector 31 and the second connector 32 are assembled, the protrusion 3111 is located within the groove 3213, and the protrusion 3111 and the groove 3213 are in sliding engagement; the protrusion 3112 is located within the groove 3214, and the protrusion 3112 and the groove 3214 are in sliding engagement. The dimension of the protrusion 3111 in the Y-axis direction is slightly smaller than the dimension of the groove 3213 in the Y-axis direction, allowing the protrusion 3111 to be accommodated within the groove 3213. Furthermore, the dimension of the protrusion 3111 in the X-axis direction is smaller than the dimension of the groove 3213 in the X-axis direction, allowing the protrusion 3111 to slide parallel to the X-direction within the groove 3213. Correspondingly, the dimension of the protrusion 3112 in the Y-axis direction is slightly smaller than the dimension of the groove 3214 in the Y-axis direction, allowing the protrusion 3112 to be accommodated within the groove 3214. Furthermore, the dimension of the protrusion 3112 in the X-axis direction is smaller than the dimension of the groove 3214 in the X-axis direction, so as to allow the protrusion 3112 to slide parallel to the X-axis direction within the groove 3214. That is, in the Y-axis direction, the two sidewalls of the protrusion 3111 slide with the two inner walls of the groove 3213 respectively, and the two sidewalls of the protrusion 3112 slide with the two inner walls of the groove 3214 respectively, to prevent the base 311 of the first connector 31 and the second connector 32 from being positioned or wobbling in the Y-axis direction, which can effectively improve the smoothness and stability of the first connector 31 and the second connector 32 when sliding in the X-axis direction.

[0125] In summary, Figure 14 In the example provided, the sliding fit between the first connector 31 and the second connector 32 is achieved by using more sliding fit surfaces, which can further improve the smoothness and stability of the first connector 31 and the second connector 32 when sliding along the X-axis direction.

[0126] In addition, the mutual cooperation of protrusion 3111 and groove 3213, and the mutual cooperation of protrusion 3112 and groove 3214, can also realize the sliding stop of the first connector 31 and the second connector 32 in the X-axis direction.

[0127] Specifically, such as Figure 14 and Figure 15 As shown, taking protrusion 3111 and groove 3213 as examples, the cross-section of protrusion 3111 is approximately rectangular, with four sidewalls: sidewall 3111a, sidewall 3111b, sidewall 3111c, and sidewall 3111d. The cross-section of groove 3213 is approximately rectangular, with four inner walls: inner wall 3213a, inner wall 3213b, inner wall 3213c, and inner wall 3213a. Sidewall 3111c slides into inner wall 3213c, and sidewall 3111d slides into inner wall 3213d, to achieve a sliding connection between the first connecting member 31 and the second connecting member 32 in the X-axis direction.

[0128] The side wall (or first mating surface) 3111a faces the inner wall 3213a, and the side wall (or second mating surface) 3111b faces the inner wall 3213b. In one possible embodiment, the side wall 3111a and the inner wall 3213a are parallel to each other. Alternatively, the side wall 3111b and the inner wall 3213b are parallel to each other.

[0129] like Figure 14 and Figure 15 As shown, when the second connector 32 slides in the opposite direction of the X-axis, the first stop surface 3110d abuts against the side wall 3211b. Simultaneously, the protrusion 3111 is located at one end within the groove 3213, and the side wall 3111a of the protrusion 3111 and the inner wall 3213a of the groove 3213 abut against each other in the X-axis direction. At this time, the connection length between the first connector 31 and the second connector 32 in the X-axis direction is the shortest. The inner wall 3213a of the groove 3213 can act as a stop for the protrusion 3111; therefore, in some cases, the inner wall 3213a can be considered as the first abutment surface.

[0130] like Figure 14 and Figure 16 As shown, when the second connector 32 slides along the X direction, the protrusion 3111 is located at the other end of the groove 3213, and the sidewall 3111b of the protrusion 3111 and the inner wall 3213b of the groove 3213 abut against each other in the X-axis direction. At this time, the connection length between the first connector 31 and the second connector 32 in the X-axis direction is the longest. The inner wall 3213b of the groove 3213 can act as a stop for the protrusion 3111; therefore, in some cases, the inner wall 3213b can be considered as a second abutment surface.

[0131] It should be noted that, in Figures 14 to 16 The example provided is an exemplary illustration of the mutual cooperation between protrusion 3111 and groove 3213. The cooperation relationship between protrusion 3112 and groove 3214 can be referred to the mutual cooperation between protrusion 3111 and groove 3213 described above, and will not be repeated here.

[0132] The number, position, and shape of the protrusions (such as protrusions 3111 and 3112) can be flexibly adjusted according to different needs. For example, the cross-section of protrusion 3111 can be circular. Correspondingly, when grooves (such as grooves 3213 and 3214) are provided in the second connector 32, the number, position, and shape of the grooves can also be flexibly adjusted according to different needs. For example, the cross-section of groove 3213 can be elliptical. Specifically, when the cross-section of protrusion 3111 is circular, the cross-section of groove 3213 can be as follows: Figure 16The shape shown is a rectangle, or it could be other shapes such as an ellipse. When the cross-section of protrusion 3111 is as follows... Figure 16 When the shape shown is rectangular, the cross-section of the groove 3213 can be as follows: Figure 16 The shape shown is a rectangle, or it could be other shapes such as an ellipse. That is, the protrusion 3111 can slide a certain distance in the groove 3213 along the X-axis, and the protrusion 3111 and the groove 3213 can provide positional limitation in the Y-axis direction to prevent the protrusion 3111 from displacing in the Y-axis direction in the groove 3213.

[0133] In the above example, the illustrative description is based on the premise that the first protrusion 3211 and the second protrusion 3212 have substantially the same structure. In other examples, the first protrusion 3211 and the second protrusion 3212 may also be different. For example, the first protrusion 3211 may adopt the following... Figure 12 The second protrusion 3212 of the hook-shaped structure shown will not be described in detail here.

[0134] In summary, in one example, the first connector 31 and the second connector 32 can adopt a variety of different structural forms to achieve a sliding fit along the X-axis direction, as well as a position stop for the maximum sliding distance.

[0135] The maximum sliding distance of the first connecting member 31 and the second connecting member 32 in the first direction can be varied. For example, as... Figure 3 , Figure 4 and Figure 6 As shown, the maximum sliding distance L2-L1 (or change in connection length) of the first connector 31 and the second connector 32 in the first direction can be less than the distance between the two buckle holes 121. For example, the maximum sliding distance L2-L1 of the first connector 31 and the second connector 32 in the first direction can be greater than or equal to half the distance between the two buckle holes 121.

[0136] Or, such as Figure 1 , Figure 3 and Figure 4 As shown, the maximum sliding distance (or change in connection length) of the first connector 31 and the second connector 32 in the first direction can be less than the length of a link 110. For example, the maximum sliding distance L2-L1 of the first connector 31 and the second connector 32 in the first direction can be greater than or equal to half the length of the link 110.

[0137] The sliding of the first connector 31 and the second connector 32 in the first direction can be achieved through active and passive adjustment methods, or a combination of both. For ease of understanding, the following examples will illustrate the active and passive adjustment methods respectively.

[0138] like Figure 17 and Figure 18 As shown, in one example provided by this utility model, the sliding of the first connector 31 and the second connector 32 in the X-axis direction can be infinitely adjusted by an active adjustment method.

[0139] The adjusting mechanism 33 includes a rotating wheel 331 (or a rotating roller) and a screw 332. The first connecting member 31 has a first limiting surface and a second limiting surface, which are arranged facing each other in a first direction. In one possible embodiment, the first and second limiting surfaces are parallel to each other. The rotating wheel 331 is located between the first and second limiting surfaces and has a threaded hole 3311 extending in the first direction. The first end of the screw 332 is fixedly connected to the second connecting member 32, and the second end of the screw 332 passes through the threaded hole.

[0140] Specifically, the base 311 has a limiting window 3113, and the cover 312 has a limiting window 3121. Both limiting windows 3113 and 3121 are approximately rectangular. Furthermore, their projections in the Z-axis direction coincide. The limiting window 3113 has four inner walls, wherein inner walls 3113a and 3113b are arranged facing each other in the X-axis direction. In one possible embodiment, inner walls 3113a and 3113b are parallel to each other. The limiting window 3121 has four inner walls, wherein inner walls 3121a and 3121b are arranged facing each other in the X-axis direction. In one possible embodiment, inner walls 3121a and 3121b are parallel to each other. That is, inner walls 3113a and 3121a constitute the aforementioned first limiting surface, and inner walls 3113b and 3121b constitute the aforementioned second limiting surface.

[0141] The rotating wheel 331 is located within the limiting windows 3113 and 3121, and its outer peripheral surface is exposed within these windows, allowing it to rotate by acting on the outer peripheral surface of the rotating shaft. The rotating wheel 331 is clearance-fitted with both the limiting windows 3113 and 3121, enabling it to rotate smoothly within these windows and effectively preventing significant shaking or displacement within the limiting windows.

[0142] The rotating wheel 331 has a first surface 331a and a second surface 331b, which are arranged opposite to each other in the X-axis direction. In one possible embodiment, the first surface 331a and the second surface 331b are parallel to each other. The first surface 331a abuts against a first limiting surface formed by inner walls 3113a and 3121a, and the second surface 331b abuts against a second limiting surface formed by inner walls 3113b and 3121b, to prevent the rotating wheel 331 from undergoing significant displacement in the X-axis direction within the limiting windows 3113 and 3121.

[0143] The first surface 331a has a threaded hole 3311. One end of the screw 332 is fixedly connected to the second connector 32, and the other end passes through the threaded hole 3311. When the wheel 331 rotates, relative rotation occurs between the wheel 331 and the screw 332, resulting in relative displacement along the X-axis. Since the wheel 331 is confined within the limiting window 3113 and the limiting window 3121, the wheel 331 drives the screw 332 to displace along the X-axis. The screw 332 is fixedly connected to the second connector 32. Therefore, when the wheel 331 is rotated, the sliding position (or the connection length in the X-axis direction) between the first connector 31 and the second connector 32 can be adjusted.

[0144] In the example provided by this utility model, the sliding position between the first connecting member 31 and the second connecting member 32 can be infinitely adjusted through the cooperation of the rotating wheel 331 and the screw 332, thereby adjusting the connection length of the first connecting member 31 and the second connecting member 32 in the X-axis direction. Furthermore, the rotating wheel 331 and the screw 332 themselves possess a self-locking effect; therefore, when the rotating wheel 331 is not rotated, the sliding position between the first connecting member 31 and the second connecting member 32 will not be affected by external forces. For example, when a user wears the device, the tension or shaking generated by the arm will not change the sliding position between the first connecting member 31 and the second connecting member 32. Only when the user moves the rotating wheel 331 will the sliding position between the first connecting member 31 and the second connecting member 32 change, thus exhibiting good reliability and stability.

[0145] Furthermore, in the above example, the exemplary illustration uses the inclusion of two limiting windows in the first connector 31, namely, the base 311 has a limiting window 3113 and the cover 312 has a limiting window 3121. In other examples, the first connector 31 may also include only one limiting window. For example, only the limiting window 3113 in the base 311 may be retained, or only the limiting window 3121 in the cover 312 may be retained. Additionally, the shape of the limiting window is not limited to the rectangle described above. It may also be a square or other polygons. Alternatively, it may be other regular or irregular shapes, which will not be elaborated upon here.

[0146] In one example, the threaded hole 3311 in the rotor 331 can be either a blind hole or a through hole. For example, when the threaded hole 3311 is a blind hole, it does not extend to the second surface 331b. When the threaded hole 3311 is a through hole, it extends to the second surface 331b.

[0147] In one example, the outer circumferential surface of the wheel 331 can be a smooth surface or a rough surface. When the outer circumferential surface of the wheel 331 is a rough surface, the coefficient of friction of the surface can be increased, allowing the hand to more easily rotate the wheel 331 through the outer circumferential surface.

[0148] In one example, the screw 332 and the second connecting member 32 can be fixedly connected by welding, bonding, or other methods. In practical applications, the connection method between the screw 332 and the second connecting member 32 can be reasonably selected according to actual needs, and this utility model does not impose any restrictions on it.

[0149] like Figure 19 As shown, in another example provided by this utility model, the sliding of the first connector 31 and the second connector 32 in the X-axis direction can be infinitely adjusted by an active adjustment method.

[0150] The adjusting mechanism includes elastic elements. Figure 19 Two elastic elements are shown, namely elastic element 333a and elastic element 333b. Elastic element 333a is connected to the first connecting member 31 and the second connecting member 32, and elastic element 333b is connected to the first connecting member 31 and the second connecting member 32. Elastic elements 333a and 333b are used to shorten or tend to shorten the connection length of the first connecting member 31 and the second connecting member 32 in a first direction through their own elastic force, thereby achieving passive adjustment.

[0151] Please refer to the following: Figure 19 and Figure 20 When the first connector 31, the second connector 32, the elastic element 333a and the elastic element 333b are assembled, the protrusion 3111 and the elastic element 333a are both located in the groove 3213, and the protrusion 3112 and the elastic element 333b are both located in the groove 3214.

[0152] Taking the protrusion 3111, the groove 3213, and the elastic member 333a as examples: The protrusion 3111 has a generally rectangular cross-section and has a side wall 3111a (or a first abutment surface) and a side wall 3111b (or a second abutment surface). The groove 3213 has a generally rectangular cross-section and has an inner wall 3213a and an inner wall 3213b. The side wall 3111b and the inner wall 3213b are arranged facing each other. In one possible embodiment, the side wall 3111b and the inner wall 3213b are parallel to each other. The elastic member 333a is located between the side wall 3111b and the inner wall 3213b, and one end of the elastic member 333a abuts against the side wall 3111b, while the other end of the elastic member 333a abuts against the inner wall 3213b.

[0153] like Figure 19 and Figure 20 As shown, when there is no external force between the first connector 31 and the second connector 32, the elastic member 333a tends to elongate under its own elastic force, causing the side wall 3111a and the inner wall 3213a to abut against each other. At this time, the connection length between the first connector 31 and the second connector 32 in the X-axis direction is the shortest.

[0154] like Figure 19 and Figure 21 As shown, when the first connector 31 and the second connector 32 are subjected to a tensile external force, such as when a user wears the wristband on their wrist and the wrist circumference is greater than the length enclosed by the wristband and the watch body, the first connector 31 and the second connector 32 will slide relative to each other under the action of the external force, and at this time, the elastic element 333a will be compressed.

[0155] It should be noted that, in Figures 19 to 21 The example provided is an exemplary illustration of the mutual cooperation of protrusion 3111, groove 3213 and elastic member 333a. The cooperation relationship of protrusion 3112, groove 3214 and elastic member 333b can be referred to the mutual cooperation of protrusion 3111, groove 3213 and elastic member 333a as described above, and will not be repeated here.

[0156] In summary, in the example provided by this utility model, when the first connector 31 and the second connector 32 are not subjected to external force, the elastic force of the elastic members 333a and 333b can keep the first connector 31 and the second connector 32 in a certain sliding position. At this time, the connection length of the first connector 31 and the second connector 32 in the X-axis direction is the shortest.

[0157] Please refer to the following: Figure 20 and Figure 23When a user wears a smartwatch and their wrist circumference is larger than the outline formed by the wristband and watch body, a force is applied to the first connector 31 and the second connector 32, increasing the connection length of the first connector 31 and the second connector 32 in the first direction (X-axis direction), thus adapting to the user's wrist circumference. Of course, in some cases, the user's wrist circumference is basically adapted to the outline formed by the wristband 10 and watch body 21. When the user moves or exercises their arm, the wrist circumference may change. Under the elastic force of the elastic elements 333a and 333b, the outline formed by the wristband 10 and watch body 21 can always match the user's wrist circumference, providing good wearing comfort and fit. In some scenarios, after the user adjusts the buckle and the wristband's fastening position, the adjustable mechanism 30 can automatically release the force according to the force of the elastic elements to a comfortable wrist circumference and tension, and achieve stepless extension and retraction of the length of the outline formed by the wristband 10 and watch body 21.

[0158] The above example illustrates an adjustment mechanism that includes two elastic elements. In other examples, the adjustment mechanism may include one or more elastic elements. These elastic elements can be the spiral structure shown in the figure, or other structural types such as spring sheets; this invention does not limit the specific type of elastic element.

[0159] In addition, the elastic component can be made of materials with good elasticity, such as steel, or it can be made of materials such as shape memory alloys, so that the elastic component has good elasticity and long-term reliability, which will not be elaborated here.

[0160] It should be noted that the above example illustrates the use of adjustable component 30 as both active and passive adjustment. In other examples, adjustable component 30 may simultaneously implement both active and passive adjustment.

[0161] For example, such as Figure 22 As shown, the adjustable component comprises two parts: a first part 30a and a second part 30b. The two parts are connected sequentially along the X-axis. The first part 30a can be the actively adjustable component 30 described in the example above, and the second part 30b can be the passively adjustable component 30 described in the example above. That is, the adjustable component can achieve active adjustment, allowing the user to actively adjust the length of the wristband (or adjustable component) according to actual wearing conditions. Additionally, the adjustable component can also achieve passive adjustment, allowing the wristband (or adjustable component) to self-adjust based on its own stress conditions, further improving wearing comfort and fit.

[0162] In another example, any of the adjustable components described above can be used independently in smartwatches or other wearable devices.

[0163] For example, such as Figure 23 and Figure 24 As shown, this utility model provides another different type of wearable device, specifically a smartwatch.

[0164] exist Figure 23 and Figure 24 In the examples provided, the smartwatches 20 all include a wristband 10, a watch body 21, and an adjustable component 30. Figure 23 and Figure 24 The wristband 10 has a different structural type in the example provided.

[0165] in, Figure 23 The smartwatch 20 shown is Figure 1 The smartwatch 20 shown has a similar structural type. Simply put, the wristband 10 includes a first band 11, a second band 12, and a clasp 13. The first band 11 and the second band 12 are of a link-type structure. The clasp 13 is of a butterfly clasp type. One end of the first band 11 is connected to the watch body 21, and the other end is connected to the clasp 13. An adjustable component 30 is connected between the clasp 13 and the second band 12. That is, one end of the second band 12 is connected to the watch body 21, and the other end is connected to the adjustable component 30, which is also connected to the clasp 13.

[0166] In one example, the first connector 31 of the adjustable component 30 can be connected to the latch 13, and the second connector 32 can be connected to the second belt body 12. Alternatively, the first connector 31 can be connected to the second belt body 12, and the second connector 32 can be connected to the latch 13. The adjustable component 30 can be fixedly connected to the latch 13 and the second belt body 12. Alternatively, a pin (or spring bar) or other connecting component can be used for the connection; this invention does not limit this.

[0167] in addition, Figure 24 The smartwatch 20 shown is Figure 2 The smartwatch 20 shown has a similar structural type. Simply put, the wristband 10 includes a first band 11, a second band 12, and a clasp 13. The first band 11 and the second band 12 are made of materials such as leather, silicone, or plastic. One end of the first band 11 is connected to the watch body 21, and the other end is connected to the adjustable component 30. The adjustable component 30 is also connected to the clasp 13. One end of the second band 12 is connected to the watch body 21.

[0168] like Figure 25As shown, in one example, the size of the connecting portion 32111 of the second connector 32 can be set to be smaller. For example, in a section perpendicular to the X-axis, the length of the connecting portion 32111 in the Y-axis direction can be less than the length of the groove 310 in the Y-axis direction. When one end of the belt (such as the first belt 11) is connected to the connecting portion 32111, one end of the first belt 11 can cover the connecting portion 32111 to avoid the connecting portion 32111 being exposed, thus making it more aesthetically pleasing and improving the user experience. In addition, the end of the first belt 11 connected to the connecting portion 32111 can also extend into the groove 310 to reduce the gap between the first connector 311 and the first belt 11. Alternatively, in some examples, the surface of the portion of the first belt 11 extending into the groove 310 can be flush with the first sidewall 3211a and the second sidewall 3212a, thereby allowing it to slide and engage with the inner wall of the groove 310. Optionally, the surface of the first belt body 11 can also be flush with the third sidewall 321a and the fourth sidewall 321b, thereby slidingly engaging with the fifth inner wall 3110c and the sixth inner wall 3120a. It is understood that this arrangement allows the second connector and the portion of the belt body outside the slide groove 310 to have flush surfaces when the connection length of the first and second connectors of the adjustable component changes in the first direction, reducing the discontinuity caused by the adjustable mechanism and making the connection between the adjustable component and the belt body more aesthetically pleasing.

[0169] Or, such as Figure 26 As shown, in a cross-section perpendicular to the X-axis, the length of the connecting portion 32111 of the second connector 32 in the Y-axis direction can be approximately equal to the length of the slide groove 310 in the Y-axis direction. That is, the outer surface of the connecting portion 32111 can be flush with the first sidewall 3211a and the second sidewall 3212a, and slide in engagement with the inner wall of the slide groove 310. Optionally, the outer surface of the connecting portion 32111 can also slide in engagement with the fifth inner wall 3110c and the sixth inner wall 3120a. It can be understood that, through this arrangement, when the connection length of the first connector and the second connector of the adjustable assembly changes in the first direction, the portion of the second connector located outside the slide groove 310 has a flush surface, thereby reducing the gap between the first connector 311 and the second connector 11, making the adjustable assembly more aesthetically pleasing.

[0170] In one example, the first connector 31 of the adjustable component 30 can be connected to the latch 13, and the second connector 32 can be connected to the first belt body 11. The adjustable component 30 can be fixedly connected to both the latch 13 and the first belt body 11. For example, the second connector 32 and the first belt body 11 can be fixedly connected by injection molding or similar methods. Alternatively, a pin (or spring bar) or other connector can be used; this invention does not limit the scope of the invention.

[0171] Understandably, the adjustable component 30 can be modularized and set on different types of wristbands and connected to different parts, so that different types of wristbands can quickly achieve stepless adjustment and stepless extension through the adjustable component 30.

[0172] In one example, the adjustable component 30 can also be integrated with some components in the wristband 10.

[0173] For example, the adjustable component 30 can be integrated with the latch 13, so that the adjustable component 30 and the latch 13 can be integrated into a latch assembly.

[0174] Alternatively, the adjustable component 30 can be integrated with the belt body to form a belt body component.

[0175] For example, the adjustable component 30 can be integrated with the first belt 11. Alternatively, the adjustable component 30 can be integrated with the second belt 12. Or, the adjustable device 30 can be integrated with both the first belt 11 and the second belt 12.

[0176] Alternatively, the adjustable component 30 can be integrated with the belt body and the buckle 13.

[0177] In summary, the adjustable component 30 can be connected to one end of the strap (such as the first strap 11 or the second strap 12). Alternatively, the adjustable component 30 can also be located within the strap; for example, the first strap 11 can be divided into two segments along its length, and the adjustable component 30 can be connected between these two segments. The material of the strap (such as the first strap 11 or the second strap 12) can specifically be plastic, silicone, metal, or other materials. The clasp 13 can specifically be a butterfly clasp, horseshoe clasp, etc., and this application does not limit the specific material of the clasp 13.

[0178] It is understood that the above example uses a smartwatch as a specific example of a wearable device. In other examples, the wearable device could also be a smart bracelet, smart glasses, etc. Alternatively, the wristband could also be a headband, etc., and this invention does not limit the scope of the invention.

[0179] In the various embodiments of this utility model, unless otherwise specified or in case of logical conflict, the terminology and / or descriptions between different embodiments are consistent and can be referenced by each other. The technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationships.

[0180] In this utility model, "multiple" refers to two or more. "And / or" describes the relationship between the associated objects, indicating that there can be three relationships.
