Buckles, strap components and wearable devices

Abstract

This utility model relates to the field of electronic device technology, and discloses a buckle, a strap assembly, and a wearable device. The buckle provided by this utility model includes an adjustable component and a cover plate. Because the pressure plate and the base in the adjustable component can rotate relative to each other, the pressure plate can be pressed against or released from the strap body passing through the base. This allows for adjustment of the position of the adjustable component on the strap body, and consequently, adjustment of the tightness of the strap assembly with the buckle. It can be continuously adjusted according to the user's wearing needs, thereby improving the user's wearing comfort. Furthermore, because the detachable connection between the cover plate and the adjustable component, and the relative rotation between the pressure plate and the base, can be operated from the side away from the wearing area, the wearable device does not need to be removed when adjusting the relative position of the adjustable component and the strap body, thus improving the convenience of adjusting the tightness of the wearable device.

Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a buckle, a strap assembly, 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 requirements for the comfort of wearing these devices. Taking smartwatches as an example, users usually need to adjust the wristband circumference to match the thickness of their wrist to achieve better wearing comfort.

[0003] However, users have different requirements for the tightness of wearable devices in different scenarios. For example, in sports, wearable devices need to be worn relatively tightly to reduce the risk of them falling off. In daily life, however, they need to be worn looser to ensure comfort. Therefore, the ease of adjusting the wristband size of wearable devices plays a crucial role in improving the user's wearing experience. Utility Model Content

[0004] This utility model provides a buckle, a strap assembly, and a wearable device to improve the adjustability of the strap assembly.

[0005] Firstly, this utility model provides a buckle, which includes an adjustable component and a cover plate. The adjustable component includes a base and a pressure plate. The base includes a first plate and a second plate, which are arranged opposite to each other, and a through hole is formed between the first plate and the second plate for a strap to pass through. The pressure plate is rotatably connected to the first plate, and the minimum distance between the pressure plate and the second plate changes during the rotation of the pressure plate relative to the first plate. Additionally, the cover plate is used to connect to the adjustable component, and when the cover plate is connected to the adjustable component, the cover plate and the first plate are located on the same side of the second plate. Using the buckle provided by this utility model, the minimum distance between the pressure plate and the second plate can be changed by the relative rotation of the pressure plate and the base, thereby enabling the pressure plate to press or release the strap passing through the through hole, thus allowing adjustment of the position of the adjustable component on the strap. This allows for adjustment of the tightness of the strap assembly with the buckle, and the adjustment method is relatively simple and can be continuously adjusted according to the user's wearing needs, thereby improving the user's wearing comfort. Furthermore, since the cover plate and the first plate are located on the same side of the second plate in the buckle provided by this utility model, when the buckle is applied to a wearable device, the cover plate and the first plate can both be located on the side of the second plate away from the wearing part. In this way, when adjusting the relative position of the adjustable component and the strap, it is not necessary to remove the wearable device. Therefore, it can improve the convenience of adjusting the tightness of the wearable device, thereby improving the user experience.

[0006] In one possible implementation of this invention, the first plate includes an avoidance notch, and the pressure plate includes a pressing portion located at the avoidance notch. This avoids interference between the pressing portion of the pressure plate and the first plate, and facilitates a reduction in the size of the adjustable component, thereby improving aesthetics.

[0007] In one possible implementation of this invention, when the pressure plate overlaps the surface of the first plate facing away from the second plate, the minimum distance from the pressing part to the second plate is d1, and the minimum distance between the first plate and the second plate is d2, where d1 < d2. This allows the pressing part to press the belt passing through the through hole firmly when the pressure plate and the base are in an overlapping state, thereby achieving a reliable connection between the adjustable component and the belt.

[0008] In one possible implementation of this invention, when the pressure plate overlaps the surface of the first plate facing away from the second plate, the minimum distance from the pressing part to the second plate is d1; when the pressure plate separates from the first plate, the minimum distance from the pressing part to the second plate is d3, where d1 < d3. That is, during the rotation of the pressure plate relative to the first plate, the minimum distance between the pressure plate and the second plate changes. This allows the adjustable component to move relative to the belt when the pressure plate separates from the first plate and the minimum distance between the pressing part and the second plate is greater than the thickness of the belt, thereby adjusting the winding length of the belt.

[0009] In one possible implementation of this invention, the first plate includes a first limiting part and a second limiting part, located on the side of the first plate opposite to the second plate. The first and second limiting parts are positioned opposite each other and spaced apart, and the direction from the first to the second limiting part is perpendicular to the extension direction of the through hole. Additionally, the latch includes a rotating shaft located between the first and second limiting parts, rotatably connected to the pressure plate, and rotatably connected to both the first and second limiting parts. This improves the reliability of the rotatable connection between the pressure plate and the first plate, thereby enhancing the structural reliability of the adjustable assembly.

[0010] In one possible implementation of this invention, the aforementioned clearance notch may be located between the first limiting portion and the second limiting portion. This allows at least a portion of the pressure plate to be located between the first limiting portion and the second limiting portion, which helps to improve the structural compactness of the adjustable component, thereby facilitating the miniaturization design of the adjustable component.

[0011] In one possible implementation of this invention, when the pressure plate overlaps the surface of the first plate facing away from the second plate, a portion of the pressure plate is located between the first limiting portion and the second limiting portion. This allows the first and second limiting portions to restrict the movement of the pressure plate along the arrangement direction of the first and second limiting portions, thereby improving the structural reliability of the adjustable assembly.

[0012] In one possible implementation of this utility model, the cover plate includes a first groove. When the cover plate is connected to the adjustable assembly, the first limiting part, the second limiting part, and the pressure plate are partially accommodated in the first groove. This allows the first and second limiting parts to limit the cover plate's movement along their arrangement direction and along their extension direction, thereby reducing movement of the cover plate relative to the adjustable assembly and improving the reliability of the connection between the cover plate and the adjustable assembly.

[0013] To achieve a detachable connection between the cover plate and the adjustable assembly, in one possible implementation, the pressure plate includes a first magnetic element, and the cover plate includes a second magnetic element, which is attracted to the first magnetic element. This attraction between the first and second magnetic elements connects the cover plate to the adjustable assembly, thereby fixing the winding length of the strap assembly with the latch. Separation of the first and second magnetic elements allows the cover plate to be detached from the adjustable assembly, enabling adjustment of the winding length of the strap assembly with the latch. This improves the ease of wearing and adjusting the strap assembly with the latch.

[0014] In one possible implementation of this invention, the pressure plate includes a pressure plate body, which includes a second groove in which a first magnetic element is accommodated. This facilitates a reduction in the thickness of the pressure plate, thereby reducing the overall thickness of the adjustable assembly and enabling a miniaturized design of the latch.

[0015] In one possible implementation of this invention, the thickness of the first magnetic element is less than or equal to the depth of the second groove. This allows the first magnetic element to be completely accommodated in the second groove, which facilitates further thinning of the pressure plate and improves its aesthetic appearance, thereby enhancing the overall appearance of the latch.

[0016] In one possible implementation of this invention, the cover plate further includes a cover plate body, which includes a third groove. The opening of the third groove is located at the bottom of the first groove, and the second magnetic element is accommodated in the third groove. This facilitates a reduction in the thickness of the cover plate, thereby improving the aesthetic appearance of the latch.

[0017] In one possible implementation of this invention, when the pressure plate overlaps the surface of the first plate facing away from the second plate, the opening of the third groove is positioned opposite to the opening of the second groove. This facilitates a miniaturized design of the latch while allowing for a larger relative area between the first and second magnetic elements, thereby enhancing the adsorption force between them and improving the reliability of the connection between the cover plate and the adjustable assembly.

[0018] In one possible implementation of this invention, the pressing part includes an inclined surface. When the pressing plate overlaps the surface of the first plate facing away from the second plate, the inclined surface faces the first plate, and the angle between the inclined surface and the surface of the first plate facing away from the second plate is an obtuse angle. This allows the pressing plate to have a pre-pressure against the first plate, thereby ensuring the reliability of the overlap between the pressing plate and the first plate in scenarios where the belt assembly with the buckle is subjected to tension or has a tendency to move relative to the adjustable assembly, thus ensuring the reliability of the connection between the adjustable assembly and the belt.

[0019] Secondly, this utility model also provides a strap assembly, which includes a strap body and a buckle as described in the first aspect, wherein the strap body passes through a through hole, and a cover plate is connected to the strap body. The strap assembly provided by this utility model has a relatively simple method for adjusting the tightness of the strap, and the tightness can be adjusted while wearing, thereby improving its adjustment convenience.

[0020] In one possible implementation of this invention, when the pressure plate overlaps the surface of the first plate opposite to the second plate, the pressure plate abuts against the belt body. This ensures a reliable connection between the buckle and the belt body.

[0021] Thirdly, this utility model also provides a wearable device, which includes a device body and the strap assembly described in the second aspect, with the strap assembly connected to the device body. The wearable device provided by this utility model can be worn using the strap assembly, and its tightness can be adjusted while worn, thereby improving the convenience of adjusting the tightness of the wearable device and enhancing the user experience.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. The same reference numerals in the figures denote the same or similar structures, and therefore repeated descriptions of them will be omitted. The terms describing position and direction in the embodiments of this utility model are illustrative based on the accompanying drawings, but changes can be made as needed, and all such changes are included within the protection scope of this utility model. The accompanying drawings of the embodiments of this utility model are for illustrating relative positional relationships only and do not represent actual proportions.

[0042] It should be noted that specific details are set forth in the following description to facilitate understanding of the present invention. However, embodiments of the present invention can be implemented in many ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the embodiments of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] In this invention, the wearable device can be, exemplarily, a smartwatch, smart bracelet, fitness tracker, smart wristband, or smart glasses, or other electronic devices that can be worn on the human body. (See reference...) Figure 1 , Figure 1 This is a schematic diagram of a wearable device using a conventional design. Figure 1 This paper describes the basic structure of the wearable device 1000 provided by this utility model, taking a smartwatch as an example. The wearable device 1000 may include a device body 100 and a strap 200. It is understood that when the wearable device 1000 is a smartwatch or smart bracelet, the device body 100 is the watch head, and the strap 200 is the wristband.

[0044] exist Figure 1 In the embodiment shown, the outline of the device body 100 is approximately circular. However, in other possible embodiments, the outline of the device body 100 may also be a regular shape such as a rectangle or an ellipse, or other irregular shapes. This utility model does not limit these shapes.

[0045] The main body 100 of the device includes a housing 101 and a display screen 102, which are fixedly connected and enclose a space to accommodate the device. The display screen 102 can be used to display images, videos, etc., and can be circular, rectangular, or other regular or irregular shapes. The space formed by the display screen 102 and the housing 101 can accommodate various functional modules and electronic components of the wearable device, such as, but not limited to, circuit boards, processors, batteries, charging management modules, communication modules, sensor modules, audio modules, speakers, receivers, and microphones, to realize multiple functions of the wearable device.

[0046] The strap 200 is connected to the main body 100 of the device, and the strap 200 can be wrapped around the user's wrist, arm, leg, or other parts of the body to wear the wearable device 1000. It can be understood that the gap between the strap 200 and the user's wearing area determines the tightness of the wearable device 1000. Since users have different requirements for the tightness of the wearable device 1000 in different scenarios, it is necessary to make the gap between the strap 200 and the user's wearing area adjustable, or, in other words, to make the length of the strap 200 wrapped around the user's wearing area adjustable, thereby improving the user's wearing comfort.

[0047] To address this issue, a mainstream solution currently is to set multiple spaced-apart fastening holes 2001 on the belt body 200, for example, see reference... Figure 2 The wearable device shown has a locking pin 300 at one end of the strap 200, which allows adjustment of the wrapping length of the strap 200 by passing the locking pin 300 through the corresponding buckle hole 2001. However, since the spacing between two adjacent buckle holes 2001 is fixed, it is difficult to achieve fine adjustment of the wrapping length of the strap 200. Therefore, users are prone to experiencing problems with the strap being too tight or too loose after wearing it.

[0048] In other solutions, such as Figure 3 As shown, Figure 3 This is a schematic diagram of another structure for a wearable device using a conventional design. Figure 3 In the illustrated solution, the wearable device 1000 may include a latch 400, which includes an adjustable component 10 and a cover plate 20. The adjustable component 10 is mounted on the strap 200 and is movable relative to the strap 200, while the cover plate 20 is fixed to one end of the strap 200. In this solution, the wearable device can be worn by connecting the cover plate 20 to the adjustable component 10.

[0049] You can continue to refer to Figure 3The adjustable component 10 includes a pressure plate 11. In the engaged state, the pressure plate 11 can be used to press the belt body 200 together, thereby achieving a fixed connection between the adjustable component 10 and the belt body 200. Additionally, the pressure plate 11 can move along... Figure 3 The belt 200 is lifted in the direction indicated by the solid arrow, and when the pressure plate 11 is in the lifted state, the belt body 200 can be released so that the adjustable component 10 can move along the length direction of the belt body 200, that is, along... Figure 3 The direction indicated by the dashed arrow is adjusted. This allows for adjustment of the size of the area enclosed by the strap 200, or the length of the strap 200 wrapped around the wearing area.

[0050] In this embodiment of the utility model, the wearable device 1000 may have an inner and an outer side. The inner side of the wearable device 1000 can be understood as the side of the wearable device 1000 facing away from the external environment, or as the side of the wearable device 1000 facing the user's wearing part when worn. Correspondingly, the outer side of the wearable device 1000 can be understood as the side of the wearable device 1000 facing the external environment, or as the side of the wearable device 1000 facing away from the user's wearing part when worn. Because in Figure 3 In the illustrated embodiment, the pressure plate 11 is located inside the adjustable component 10. Therefore, when it is necessary to adjust the relative position between the adjustable component 10 and the strap 200, the wearable device 1000 must be removed from the wearing area before the adjustment operation can be performed. This makes adjusting the tightness of the wearable device 1000 inconvenient, thus affecting the user experience.

[0051] In view of this, the present invention provides a buckle whose relative position to the strap is not affected by whether the wearable device is being worn, thereby satisfying the tightness adjustment requirements of the wearable device when it is being worn, thus improving the convenience of adjusting the tightness of the wearable device and enhancing the user experience.

[0052] The buckle provided in this embodiment can be applied to various types of strap components such as wristbands and headbands, allowing users to wear wearable devices such as smartwatches, smart bracelets, or smart glasses through the strap components.

[0053] For example, when the strap component is a wristband, the user can wear the wearable device on their wrist. To facilitate understanding of the present invention, the following description uses the application of a locking mechanism in a smartwatch wristband as an example; the application of this locking mechanism in other strap components is similar. To further illustrate the solution provided by the present invention, the following detailed description will be provided in conjunction with the accompanying drawings and specific embodiments.

[0054] Figure 4 This is a schematic diagram of a belt assembly provided by this utility model. Figure 4 As shown, the strap assembly provided by this utility model includes a strap body 200 and a buckle 400. The buckle 400 includes an adjustable component 10 and a cover plate 20. Both the adjustable component 10 and the cover plate 20 are installed on the strap body 200, and there is a certain distance between the adjustable component 10 and the cover plate 20 along the length direction of the strap body 200. In this way, the length of the strap body 200 for wrapping around the wearing part can be fixed by connecting the cover plate 20 and the adjustable component 10, thereby ensuring the wearing stability of the wearable device using this strap assembly.

[0055] exist Figure 4 In the illustrated embodiment, the cover plate 20 is connected to the adjustable component 10. Additionally, refer to... Figure 5 , Figure 5 for Figure 4 The diagram shows the structure of the belt assembly in another state. Figure 5 This can be used to demonstrate the structure of the belt assembly when the cover plate 20 and the adjustable component 10 are in the separated state. See also... Figure 4 and Figure 5 It is understood that in the belt assembly provided in this embodiment of the present invention, the cover plate 20 and the adjustable assembly 10 are detachably connected.

[0056] You can continue to refer to Figure 5 In this embodiment of the invention, the adjustable component 10 includes a pressure plate 11 and a base 12. The base 12 is sleeved on the belt body 200, or in other words, the belt body 200 passes through the base 12. The pressure plate 11 and the base 12 are rotatably connected so that the pressure plate 11 can press the belt body 200 by rotating relative to the base 12, thereby achieving a fixed connection between the adjustable component 10 and the belt body 200. Furthermore, by rotating relative to the base 12, the belt body 200 can be released, thereby allowing adjustment of the relative position between the adjustable component 10 and the belt body 200, thus achieving adjustment of the winding length of the belt component.

[0057] To facilitate understanding of the structure of the latch 400 provided by this utility model, please refer to... Figure 6 , Figure 6 This is a schematic diagram of an adjustable component provided in an embodiment of the present invention. To assemble the base 12 and the belt 200, the base 12 may include a first plate 121 and a second plate 122, which are disposed opposite to each other. A through hole 123 is formed between the first plate 121 and the second plate 122, through which the belt 200 can pass to the through hole 123 to mount the base 12 onto the belt 200.

[0058] Figure 7 for Figure 6An exploded view of the adjustable component shown. Figure 7 As shown, the pressure plate 11 is rotatably connected to the first plate 121. Specifically, the adjustable component 10 also includes a rotating shaft 13, which is rotatably connected to the pressure plate 11 and the first plate 121, thereby realizing the rotatable connection between the pressure plate 11 and the first plate 121.

[0059] In this utility model, the specific arrangement of the rotating shaft 13 is not limited, for example in Figure 7 In the illustrated embodiment, there is one rotating shaft 13, which passes through the pressure plate 11, and both ends of the rotating shaft 13 are rotatably connected to the first plate 121. In other embodiments of this utility model, there may be two rotating shafts 13, located on both sides of the pressure plate 11 and rotatably connected to the pressure plate 11, and both rotating shafts 13 are also rotatably connected to the first plate 121. Of course, in practical applications, the rotating shaft 13 may also adopt other possible design forms, which will not be listed here.

[0060] You can continue to refer to Figure 7 The first plate 121 includes a first limiting part 14 and a second limiting part 15. The first limiting part 14 and the second limiting part 15 are located on the side of the first plate 121 opposite to the second plate 122. The first limiting part 14 and the second limiting part 15 are arranged opposite to each other and spaced apart, and the direction from the first limiting part 14 to the second limiting part 15 is perpendicular to the extension direction of the through hole 123. In some embodiments of this utility model, the area of ​​the first plate 121 where the first limiting part 14 and the second limiting part 15 are provided can be regarded as a locally thickened area of ​​the first plate 121, thus its structural strength is higher. Therefore, the rotating shaft 13 can be located between the first limiting part 14 and the second limiting part 15 and rotatably connected to the first limiting part 14 and the second limiting part 15, so as to realize the rotatable connection between the pressure plate 11 and the first plate 121 while ensuring the structural reliability of the adjustable component 10.

[0061] Refer to together Figure 6 and Figure 7 When the pressure plate 11 overlaps the surface of the first plate 121 on the side facing away from the second plate 122, a portion of the pressure plate 11 is located between the first limiting part 14 and the second limiting part 15. That is, the portion of the pressure plate 11 that overlaps the first plate 121 is located between the first limiting part 14 and the second limiting part 15. This allows the first limiting part 14 and the second limiting part 15 to restrict the movement of the pressure plate 11 along the arrangement direction of the first limiting part 14 and the second limiting part 15, thereby improving the structural reliability of the adjustable assembly 10.

[0062] like Figure 7As shown, the first plate 121 of the base 12 further includes a clearance notch 1211, and the pressure plate 11 further includes a pressing portion 114, which can be located at the clearance notch 1211. During the rotation of the pressure plate 11 relative to the base 12, the clearance notch 1211 can be used to allow the pressing portion 114 to be pressed or released on the belt passing through the through hole 123.

[0063] In addition, in some embodiments of this utility model, for example in Figure 7 In the illustrated embodiment, the clearance notch 1211 may be located between the first limiting portion 14 and the second limiting portion 15. This allows at least a portion of the pressure plate 11 to be located between the first limiting portion 14 and the second limiting portion 15, which helps to improve the structural compactness of the adjustable component 10, thereby facilitating the miniaturization design of the adjustable component 10.

[0064] As described above, in the latch 400 provided by this utility model, the cover plate 20 and the adjustable component 10 are detachably connected. Therefore, in some embodiments of this utility model, reference can be made to... Figure 7 The pressure plate 11 includes a first magnetic element 111. Additionally, refer to... Figure 8 , Figure 8 This is a schematic diagram of a cover plate provided in an embodiment of the present invention. The cover plate 20 includes a second magnetic element 201, which is used to attract the first magnetic element 111. In this way, the cover plate 20 can be connected to the adjustable assembly 10 through the attraction of the first magnetic element 111 and the second magnetic element 201, thereby fixing the winding length of the tape 200; and the cover plate 20 can be disassembled from the adjustable assembly 10 by separating the first magnetic element 111 and the second magnetic element 201, thereby adjusting the winding length of the tape 200.

[0065] You can continue to refer to Figure 7 The pressure plate 11 also includes a pressure plate body 112, which includes a second groove 1121, into which the first magnetic element 111 can be accommodated. This is beneficial for reducing the thickness of the pressure plate 11, thereby reducing the overall thickness of the adjustable assembly 10, which is conducive to achieving a miniaturized design of the latch 400.

[0066] It is understood that in some embodiments of this utility model, the thickness of the first magnetic element 111 is less than the depth of the second groove 1121, so that the first magnetic element 111 is completely accommodated in the second groove 1121. This is beneficial for further thinning of the pressure plate 11 and for improving the appearance of the pressure plate 11, thereby improving the overall appearance of the latch 400.

[0067] In some embodiments of this utility model, such as Figure 7As shown, the pressure plate 11 may also include a first cover 113, which is disposed in the groove of the second groove 1121 and is fixedly connected to the pressure plate body 112. The connection method may be, but is not limited to, bonding or threaded connection, thereby confining the first magnetic element 111 in the second groove 1121.

[0068] It is worth mentioning that, Figure 7 In the illustrated embodiment, the opening of the second groove 1121 is located on the side of the pressure plate body 112 facing away from the base 12. However, in other embodiments of this invention, the opening of the second groove 1121 may also be located on the side of the pressure plate body 112 facing the base 12. Therefore, this invention does not limit the specific manner in which the second groove 1121 is formed.

[0069] Figure 9 for Figure 8 An exploded view of the cover plate shown is provided. The cover plate 20 includes a cover plate body 202, which can serve as a support for other structures of the cover plate 20. Other structures of the cover plate 20 can be connected to the cover plate body 202, for example, the second magnetic element 201 can be connected to the cover plate body 202. Additionally, the cover plate body 202 can also serve as an external component of the cover plate 20, used to conceal other structures of the cover plate 20. That is, when the cover plate 20 is connected to the adjustable assembly 10, the other structures of the cover plate 20 can be located on the side of the cover plate body 202 facing the adjustable assembly 10, and the projection of the cover plate body 202 onto the adjustable assembly 10 covers the other structures of the cover plate 20, thereby improving the aesthetic appearance of the latch 400.

[0070] As described above, the cover plate 20 is connected to the belt body 200, and thus... Figure 9 In the illustrated embodiment, the cover plate 20 also includes a pressure cap 203, which is disposed opposite to the cover plate body 202. Thus, the cover plate 20 and the belt body 200 are connected by inserting one end of the belt body 200 between the pressure cap 203 and the cover plate body 202, and by connecting the pressure cap 203 to the cover plate body 202.

[0071] You can continue to refer to Figure 9 In this embodiment, the pressure cap 203 is detachably connected to the cover plate body 202, which can be exemplarily locked by fasteners such as screws 30, thus facilitating the maintenance or replacement of the cover plate 20 and the belt body 200. In other embodiments of this utility model, the pressure cap 203 and the cover plate body 202 can also be connected by riveting or welding to improve the connection reliability between the cover plate 20 and the belt body 200.

Figure 9 and Figure 10 As can be seen, the cover plate body 202 includes a first groove 2021, and when the cover plate 20 is connected to the adjustable component 10, the first limiting part 14 and the second limiting part 15 are accommodated in the first groove 2021. Additionally, a portion of the pressure plate 11 is also accommodated in the first groove 2021. For example, all or part of the pressure plate 11, excluding the pressing part 114, is accommodated in the first groove 2021; for example, the pressure plate body 112 can be accommodated in the first groove 2021. In this way, the first limiting part 14 and the second limiting part 15 can be used to limit the cover plate 20 along the arrangement direction of the first limiting part 14 and the second limiting part 15, and also to limit the cover plate 20 along the extension direction of the first limiting part 14 and the second limiting part 15, thereby reducing the movement of the cover plate 20 relative to the adjustable component 10 and improving the connection reliability between the cover plate 20 and the adjustable component 10.

[0073] You can continue to refer to Figure 10 In some embodiments of this utility model, the cover plate 20 may include a third groove 2022, the opening of which is located at the bottom of the first groove 2021, so that the second magnetic element 201 can be accommodated in the third groove 2022. This is beneficial to reducing the thickness of the cover plate 20, thereby improving the appearance of the latch 400.

[0074] Additionally, in order to confine the second magnetic element 201 within the third groove 2022, such as Figure 10 As shown, the cover plate 20 may also include a second cover 204, which is located in the groove of the third groove 2022 and is connected to the cover plate body 202. The connection method may be, but is not limited to, adhesive or threaded connection, etc., and is not limited here.

[0075] When the pressure plate 11 overlaps the surface of the first plate 121 facing away from the second plate 122, as Figure 10 As shown, the opening of the second groove 1121 is positioned opposite to the opening of the third groove 2022. This allows for a larger relative area between the first magnetic element 111 and the second magnetic element 201, thereby increasing the adsorption force between them and improving the connection reliability between the cover plate 20 and the adjustable assembly 10. In other embodiments of this invention, the first magnetic element 111 can be attached to other positions on the pressure plate 11 by bonding or other means, and the second magnetic element 201 can be attached to other positions on the cover plate body 202 by bonding or other means, as long as adsorption between the first magnetic element 111 and the second magnetic element 201 can be achieved.

[0076] exist Figure 10 In the state shown, the crimping part 114 can abut against the belt body 200 so that the crimping part 114 can press the belt body 200 through the hole between the first plate 121 and the second plate 122, thereby realizing the fixed connection between the adjustable component 10 and the belt body 200.

[0077] Understandably, in Figure 10 In the shown state, the length of the strap 200 for wrapping around the wearing part is fixed, or it can be understood as the connection between the buckle and the strap 200 when the wearable device is in the wearing state. When it is necessary to adjust the length of the strap for wrapping around the wearing part, firstly, the cover plate 20 is separated from the adjustable component 10, at which point the strap component can be in a certain position. Figure 5 The state shown.

[0078] Reference Figure 11 , Figure 11 for Figure 5 The image shows a BB cross-sectional view of the belt body component. Figure 11 In the shown state, that is, when the pressure plate 11 overlaps the surface of the first plate 121 facing away from the second plate 122, the minimum distance from the pressing part 114 to the second plate 122 is d1, and the minimum distance between the first plate 121 and the second plate 122 is d2, where d1 < d2. The thickness D of the belt body 200 can satisfy d1 < D < d2, so that the pressing part 114 can reliably abut against the belt body 200.

[0079] like Figure 11 As shown, the pressing part 114 also includes a bevel 1141. When the pressing plate 11 overlaps the surface of the first plate 121 facing away from the second plate 122, the bevel 1141 faces the first plate 121, and the angle α between the bevel 1141 and the surface of the first plate 121 facing away from the second plate 122 is an obtuse angle, wherein the angle α can be, for example, 130°, 135°, or 145°. This allows the pressing plate 11 to have a pre-pressure force pressing against the first plate 121, thereby ensuring the reliability of the overlap between the pressing plate 11 and the first plate 121 in scenarios where the belt 200 is subjected to tension or has a tendency to move relative to the adjustable component 10, thus ensuring the reliability of the connection between the adjustable component 10 and the belt 200, and consequently ensuring the reliability of the wearable device.

[0080] exist Figure 11 In the state shown, the pressure plate 11 can be pried open in the direction indicated by the arrow. The pressure plate 11 can rotate relative to the base 12, and the pressure plate 11 separates from the base 12, so that the belt assembly can be in the position shown. Figure 12 The state shown.

[0081] Also refer to Figure 13 , Figure 13 for Figure 12 The diagram shows a CC cross-sectional view of the belt assembly. When the pressure plate 11 separates from the first plate 121, the minimum distance from the pressing part 114 to the second plate 122 is d3. This is determined by comparison. Figure 11 and Figure 13 It can be understood that d1 < d3. That is, during the rotation of the pressure plate 11 relative to the first plate 121, the minimum distance between the pressure plate 11 and the second plate 122 changes. Specifically, during the process of the pressure plate 11 and the first plate 121 transitioning from overlapping to separation, the minimum distance between the pressing part 114 and the second plate 122 increases. When this distance increases to a value greater than or equal to the thickness of the belt 200, the pressure plate 11 can release the belt 200, at which point it can move along... Figure 12 The direction indicated by the dashed arrow is used to adjust the relative position of the adjustable component 10 and the belt body 200. When the adjustable component 10 is adjusted to the appropriate position, such as... Figure 12 As shown, the pressure plate 11 can be pressed in the direction indicated by the solid arrow to re-attach the pressure plate 11 to the base 12 and tighten the strap 200. This achieves the adjustment of the length of the strap 200 for wrapping around the wearing position.

[0082] From the above Figure 10 As can be seen, in this embodiment of the invention, when the cover plate 20 is connected to the adjustable component 10, the cover plate 20 and the first plate 121 are located on the same side of the second plate 122. Therefore, when this strap assembly is applied to a wearable device, the cover plate 20 and the first plate 121 can both be located on the side of the second plate 122 facing away from the user's wearing part, that is, on the outside of the wearable device. In this way, the separation of the cover plate 20 from the adjustable component 10 and the rotation of the pressure plate 11 relative to the base 12 can both be performed on the outside of the wearable device. That is to say, the adjustment of the winding length of the strap assembly can be performed when the wearable device is worn on the wearing part without having to remove the wearable device, thereby improving the convenience of adjusting the winding length of the strap assembly and enhancing the user experience.

[0083] In the above embodiments, the specific structure of the strap assembly provided by this utility model is shown using a single-segment strap as an example. When the strap is dual-segmented, that is, when the strap assembly includes two independent straps, the two independent straps can be connected to the main body of the wearable device respectively. In addition, the adjustable component 10 is installed on one strap, and the cover plate 20 is installed on the other strap. However, the specific setting of the buckle 400 can refer to any of the above embodiments, and will not be described in detail here.

[0084] This invention does not limit the material of the belt body; for example, it can be a Milanese belt body or a nylon braided belt body, etc.

[0085] Furthermore, the above embodiments are merely exemplary demonstrations of the specific configuration of the belt assembly and the buckle 400 provided by this utility model. Based on this, a series of adaptive modifications can be made to the specific configuration of the relevant structure according to actual design requirements. For example, in addition to being detachably connected by magnetic adsorption, the cover plate 20 and the adjustable component 10 can also be detachably connected by snap-fit ​​or other means. These are not listed one by one here, but they should all be understood to fall within the protection scope of this utility model.

The technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationship.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
