Description

Technical Field

[0001] The present application relates to the technical field of wearable devices, and in particular to a buckle structure, a buckle ring structure, a watch strap and a wearable device. Background Art

[0002] Wearable devices refer to portable devices that can be worn directly on the body or integrated into the user's clothes or accessories. With the rapid improvement of information technology, the application of smart wearable devices is becoming more and more extensive, such as smart watches and smart glasses, making wearable devices not only a hardware device, but also realize powerful functions through software support and data interaction, and are deeply loved by users.

[0003] In order to realize the convenient wearing of the device, the wearable device usually has a fixed belt for wearing. For example, taking a watch as an example, the strap as a fixed belt usually includes two parts, such as a first belt body and a second belt body, one end of the first belt body and the second belt body are respectively connected to the dial of the watch, and the other ends of the first belt body and the second belt body are snap-fitted, so that the first belt body, the second belt body and the dial can be connected as a closed ring as a whole to surround and wear on the user's wrist and other parts. The first belt body and the second belt body are generally snap-fitted by a horseshoe buckle and a buckle hole. For example, a horseshoe buckle can be provided on the other end of the first belt body, and a buckle hole can be opened on the second belt body. The second belt body can pass through the horseshoe buckle, and the buckle pin of the horseshoe buckle is matched with the buckle hole to realize the connection between the first belt body and the second belt body. A strap ring can also be set on the first belt body, and the strap ring can be movably arranged along the extension direction of the first belt body. After the other end of the second belt body passes through the horseshoe buckle, it can be inserted into the strap ring to prevent the other end of the second belt body from warping.

[0004] The above-mentioned wearable devices such as watches have the problem of poor user experience. Utility Model Content

[0005] The embodiments of the present application provide a buckle body structure, a buckle ring structure, a watch strap and a wearable device, which are highly convenient to use and help improve the user experience and service life of the watch strap and the wearable device.

[0006] A first aspect of an embodiment of the present application provides a buckle structure for being set on a strap of a wearable device, wherein the buckle structure is detachably connected to a first strap body and a second strap body of the strap, thereby achieving a detachable connection between the first strap body and the second strap body through the buckle structure.

[0007] The buckle structure includes a base, a first clamping portion, and a second clamping portion. The base and the first clamping portion are used to be clamped with the first button hole of the first belt body, so that the buckle structure and the first belt body are assembled and fixed together in a detachable clamping manner. The first clamping portion and the second clamping portion are used to be clamped with the second button hole of the second belt body, so that the buckle structure and the second belt body can also be assembled and fixed together in a detachable clamping manner.

[0008] In actual use, the buckle structure can be assembled on one of the first strap body and the second strap body. When wearing or removing the watch strap, the buckle structure can be assembled or removed from the other of the first strap body and the second strap body. For example, the buckle structure is buckled on the first buckle hole of the first strap body through the base and the first buckle part. When wearing, the first buckle part and the second buckle part of the buckle structure can be buckled with the second buckle hole of the second strap body, so that the first strap body and the second strap body can be assembled and connected together. When removing the watch strap, the buckle structure can be separated from the second buckle hole of the second strap body. That is, when wearing the device, the buckle structure on the first strap body can be directly buckled with the second buckle hole on the second strap body. When removing the device, the buckle structure can be separated from the second buckle hole on the second strap body. The wearing and removal methods are simple, and the operation is convenient and quick, which greatly improves the convenience and user experience.

[0009] In a possible implementation, the first clamping portion is disposed on one side of the base, the base is used to abut against the first surface of the first belt body, the first clamping portion is used to pass through the first buckle hole, and the first clamping portion is used to abut against the second surface of the first belt body. By abutting the base with the first surface of the first belt body, the first clamping portion and the second surface of the first belt body, the buckle body structure and the first belt body are fixedly limited, so that the buckle body structure is buckled and set on the first belt body. The buckle matching design is simple, easy to implement and has low manufacturing cost.

[0010] In a possible implementation, the second clamping portion is located on the side of the first clamping portion facing away from the base, the second clamping portion is used to pass through the first buckle hole and protrude on the second surface of the first belt body, the second clamping portion is used to pass through the second buckle hole, and the second clamping portion is used to abut against the third surface of the second belt body. By abutting the first clamping portion with the fourth surface of the second belt body and the second clamping portion with the third surface of the second belt body, the buckle body structure and the second belt body are fixedly limited, so that the buckle body structure is buckled on the second belt body, thereby achieving the buckle fit of the first belt body and the second belt body. The buckle fit is simple in design, easy to implement and has a low manufacturing cost.

[0011] In a possible implementation, the outer contour dimensions of the base are respectively larger than the outer contour dimensions of the first clip portion and the second clip portion. The first clip portion and the second clip portion can pass through the first buckle hole, ensuring that the base cannot pass through the first buckle hole, and abuts against the first surface of the first belt body, thereby ensuring the snap-fitting strength of the buckle body structure and the first belt body and improving the stability of the assembly and fixation of the buckle body structure and the first belt body.

[0012] The outer contour size of the first clamping part is larger than that of the second clamping part, so that the second clamping part can conveniently pass through the second buckle hole of the second strap and abut against the third surface. However, the first clamping part cannot conveniently pass through the second buckle hole, so it can abut against the fourth surface, thereby improving the assembly stability of the first strap and the second strap, and facilitating the separation of the second clamping part from the second buckle hole, thereby realizing the separation and disassembly of the first strap and the second strap, making the operation more convenient and improving the wearing convenience of the watch strap.

[0013] In a possible implementation, the buckle body structure further includes a first connecting portion, the first connecting portion is located between the base and the first clamping portion, and the first clamping portion is connected to the base through the first connecting portion. The first connecting portion is used to be inserted into the first buckle hole, and the outer contour size of the first connecting portion is smaller than the outer contour size of the first clamping portion. It is ensured that the first clamping portion abuts against the second surface of the first belt body after passing through the first buckle hole, and the first connecting portion is accommodated in the first buckle hole.

[0014] The buckle body structure also includes a second connecting portion, which is located between the first clamping portion and the second clamping portion, and the second clamping portion is connected to the first clamping portion through the second connecting portion, and the second connecting portion is used to pass through the second buckle hole, and the outer contour size of the second connecting portion is smaller than the outer contour size of the second clamping portion. It is ensured that the second clamping portion abuts against the third surface of the second belt body after passing through the second buckle hole, and the second connecting portion is accommodated in the second buckle hole.

[0015] In one possible implementation, the gap between the first clip part and the base along the thickness direction is greater than or equal to the thickness of the first belt body, so that after the first clip part passes through the first buckle hole, the base and the first clip part respectively abut against the first surface and the second surface, which facilitates the assembly operation, reduces the difficulty of assembly, and improves the convenience of assembly.

[0016] The gap between the second clamping part and the first clamping part in the thickness direction is greater than or equal to the thickness of the second belt body. After the second clamping part passes through the second buckle hole, the first clamping part and the second clamping part respectively abut against the fourth surface and the third surface, which facilitates the assembly operation, reduces the assembly difficulty, and improves the assembly convenience.

[0017] In a possible implementation, the thickness of the base is smaller than the thickness of the second clipping part. On the one hand, the thickness of the second clipping part can be relatively thick, so that the second clipping part is not easy to fall out of the second buckle hole in the wearing scenario, reducing or avoiding the risk of the first strap body and the second strap body falling off and separating. On the other hand, it can be understood that the base abuts against the first surface of the first strap body. When worn, the base is located between the user's skin and the first surface, so that the thickness of the base can be relatively small, reducing or avoiding the problem of scratching the hand due to the thick base, and making the side of the strap facing the user a relatively smooth curved surface when worn, thereby improving wearing comfort.

[0018] The thickness of the first clamping part is smaller than that of the second clamping part. The first clamping part is located between the first belt body and the second belt body, so that the thickness of the first clamping part is smaller, the first belt body and the second belt body can fit better during assembly, and wrinkles, bulges, etc. at the buckle body structure are reduced or avoided, which further helps to improve the wearing comfort.

[0019] In a possible implementation, the second clamping portion includes an annular arcuate wall surface, which extends from one end of the second clamping portion away from the base to one end of the second clamping portion adjacent to the base, and the outer contour of the arcuate wall surface gradually increases from the end of the second clamping portion away from the base to the end of the second clamping portion adjacent to the base. The second clamping portion can be in the shape of a mushroom head, and the entire outer wall surface of the second clamping portion is relatively smooth and rounded, which is conducive to improving the aesthetics and safety, and avoiding the second clamping portion protruding on the third surface of the second strap body from scratching the user. In addition, the second clamping portion is easier to pass through the second buckle hole and abut against the third surface of the second strap body, which is easy to operate and is conducive to improving the wearing convenience of the watchband.

[0020] In a possible implementation, a surface of the base that is opposite to the first clamping portion is flat, which further reduces or avoids the problem of the base scratching the hand and improves wearing comfort.

[0021] A second aspect of an embodiment of the present application provides a buckle structure for being set on a strap of a wearable device. The buckle structure is detachably connected to a first strap body of the strap, and the second strap body is used to be inserted into the buckle structure. The buckle structure can be used to limit the retraction of the second strap body to avoid warping of the second strap body.

[0022] The buckle structure includes a bottom wall, and a third clamping portion is provided on the inner surface of the bottom wall. The buckle structure is used to be arranged around the first strap, the bottom wall is used to abut against the first surface of the first strap, the third clamping portion is used to pass through the first buckle hole of the first strap, and the third clamping portion is used to abut against the second surface of the first strap. The buckle structure and the first strap are fixed in position by abutting the bottom wall with the first surface of the first strap, the third clamping portion and the second surface of the first strap, so that the buckle structure can be assembled on the first strap through the first buckle hole, avoiding the buckle structure from falling off, ensuring the normal use of the watch strap, and improving the use experience and service life.

[0023] In a possible implementation, the outer contour size of the third clamping portion is smaller than the outer contour size of the bottom wall. The third clamping portion can pass through the first buckle hole to ensure that the bottom wall cannot pass through the first buckle hole, and abuts against the first surface of the first belt body, thereby ensuring the buckle fit between the buckle structure and the first belt body and improving the stability of the assembly and fixation of the buckle structure and the first belt body.

[0024] In a possible implementation, the gap between the third clamping portion and the inner surface of the bottom wall along the thickness direction is greater than or equal to the thickness of the first belt body. After the third clamping portion passes through the first buckle hole, the bottom wall and the third clamping portion abut against the first surface and the second surface respectively, which facilitates the assembly operation, reduces the difficulty of assembly, and improves the convenience of assembly.

[0025] In a possible implementation, the buckle structure further includes a top wall and two opposite arc-shaped side walls, the top wall is opposite to the side walls, and the two ends of the arc-shaped side walls are respectively connected to the bottom wall and the side walls to form a closed ring. By making the buckle structure a closed ring structure, the stability of the buckle structure on the end limit of the second belt body can be improved, the second belt body can be better constrained, and the wearing comfort and aesthetics can be improved. In addition, the arc-shaped side walls have a good smooth transition, which reduces or avoids the corners of the buckle structure from scratching the user.

[0026] In a possible implementation, the outer surface of the bottom wall is a plane. The buckle structure further includes a third connecting portion, the third connecting portion is located between the bottom wall and the third clamping portion, and the third clamping portion is connected to the bottom wall via the third connecting portion.

[0027] The third connecting part is used to be inserted into the first button hole, and the outer contour size of the third connecting part is smaller than the outer contour size of the third clamping part, ensuring that the third clamping part abuts against the second surface of the first belt body after passing through the first button hole, and the third connecting part is accommodated in the first button hole.

[0028] In one possible implementation, the molding material of the buckle structure includes a hard material, so that the buckle structure has good hardness and strength, reducing or avoiding the risk of the buckle structure breaking, extending the service life of the strap, and improving the user experience.

[0029] The third aspect of the embodiment of the present application provides a watch strap, comprising a first strap body, a second strap body and any of the above-mentioned buckle structures, wherein the buckle structure is detachably connected to the first strap body and the second strap body. The buckle structure is used to realize the snap fit between the first strap body and the second strap body, and the wearing and removing methods are simple and easy to operate, with excellent convenience and user experience.

[0030] In a possible implementation, the first belt body has a plurality of first buttonholes, which are arranged at intervals along the extension direction of the first belt body. The second belt body has a plurality of second buttonholes, which are arranged at intervals along the extension direction of the second belt body.

[0031] The buckle structure can be snap-fitted with any first button hole, and the buckle structure can also be removed from any first button hole. The position of the buckle structure on the first belt body can be freely adjusted, so that the buckle structure can be flexibly assembled on the first belt body along the extension direction of the first belt body. It has a high degree of assembly freedom and meets different assembly and usage requirements.

[0032] The buckle body structure can also be snap-fitted with any second buckle hole. When the buckle body structure is matched with the second buckle holes at different positions on the second strap body, the lengths of the straps formed by the first strap body and the second strap body are different, so the length of the strap can be adjusted to meet the matching requirements of different wrist circumferences and improve wearing comfort.

[0033] In a possible implementation, the watch strap further comprises any of the above-mentioned buckle structures, and the buckle structure is detachably connected to the first strap body. By making the buckle detachably assembled on the first strap body, the buckle structure is prevented from falling off, ensuring the normal use of the watch strap, and improving the use experience and service life.

[0034] Furthermore, the buckle structure can also be snap-fitted with any first buckle hole on the first strap, that is, the buckle structure can be snap-fitted to any first buckle hole on the first strap, and the buckle structure can also be removed from any first buckle hole, and the position of the buckle structure on the first strap can be freely adjusted, so that the buckle structure can be flexibly assembled on the first strap along the extension direction of the first strap to meet different wrist circumference requirements and usage requirements. That is, under the condition that the buckle structure can be moved along the extension direction of the first strap to match different wrist circumference requirements, the buckle structure is stably assembled on the first strap.

[0035] The position of the buckle structure on the first belt body can be adjusted by snap-fitting with different first button holes, and the position of the buckle structure on the first belt body can also be adjusted by snap-fitting with different first button holes. The positions of the buckle structure and the buckle structure on the first belt body can be freely adjusted according to the wearing comfort of the user, and even the positions of the buckle structure and the buckle structure can be swapped, which has a high degree of design freedom and flexibility.

[0036] In addition, the relative positions of the buckle structure and the buckle ring structure on the first belt body can be adjusted. Therefore, the positions of the buckle structure and the buckle ring structure can be reasonably adjusted, such as keeping a relatively long distance between the buckle structure and the buckle ring structure (along the extension direction of the first belt body), so that when the second belt body is inserted into the buckle ring structure after being snap-fitted with the buckle structure to close the second belt body, the second belt body can be smoothly inserted into the buckle ring structure without bulging, thereby avoiding the risk of nail collapse caused by the second belt body being separated from the buckle structure due to the bulging of the second belt body, and having a better closing experience.

[0037] In one possible implementation, the first strap body and the second strap body have the same structure, and the first strap body and the second strap body can be formed by using the same structural type mold, thereby reducing the number of different types of molds. In addition, a watch strap can be composed of a buckle structure, a buckle body structure and two strap bodies of the same shape (the first strap body and the second strap body), and the number of components constituting the watch strap is greatly reduced, which can significantly reduce the cost and molding difficulty of the entire watch strap.

[0038] In a possible implementation, the molding material of the first belt body and the second belt body includes a flexible material, which has higher flexibility and wearing comfort. In addition, the first buckle hole and the second buckle hole can be given good flexible deformation ability, which is convenient for the first and second clamping parts of the buckle body structure to pass through the first buckle hole and abut on the first and second belt bodies, and also convenient for the third clamping part of the buckle ring structure to pass through the first buckle hole and abut on the first belt body, which is convenient for buckle assembly operation and helps to improve the convenience of wearing and disassembly.

[0039] The fourth aspect of the embodiments of the present application also provides a watch strap, including a first strap body, a second strap body and any one of the above-mentioned buckle structures, the buckle structure is detachably connected to the first strap body, and the second strap body is used to be inserted into the buckle structure.

[0040] A fifth aspect of an embodiment of the present application provides a wearable device, comprising a device body and any one of the above-mentioned straps, wherein both ends of the device body are respectively connected to a first strap body and a second strap body of the strap.

[0041] In a possible implementation, the wearable device includes a watch or a bracelet. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0073] The embodiment of the present application provides a wearable device, which may be a watch (mechanical watch and electronic watch), a smart watch, a bracelet, a smart bracelet, etc. It may also be an augmented reality (AR) device, a virtual reality (VR) device, and a mixed reality (MR) device, etc. For example, it may be VR glasses, AR glasses, AR helmets, VR helmets, MR helmets, etc. The wearable device may also be a wearable electronic health detection device, such as a wearable blood pressure monitor, a blood oximeter, etc.

[0074] Alternatively, in some examples, the wearable device may also be a wearable decorative device such as a belt, a waistband, a bracelet, an anklet, or a ring.

[0075] Figure 1 A schematic diagram of the structure of a wearable device when worn provided in an embodiment of the present application.

[0076] For example, in the examples of this application, see Figure 1 As shown, the wearable device 100 is a watch as an example for explanation. The watch can be a mechanical watch, or the watch can also be an electronic watch, a smart watch, etc. The watch can be worn on the wrist of the user and can be used to realize one or more functions such as time display, timing, time reporting, message notification, communication interaction, motion detection, heart rate monitoring, blood oxygen level detection, etc.

[0077] The wearable device 100 may include a device body 101 and a strap 102. The device body 101 may be connected to the strap 102, and the wearable device 100 may be worn through the strap 102, so that the device body 101 is worn on the user's wrist. The strap 102 plays a fixing role so that the device body 101 can be stably worn. To facilitate wearing, the strap 102 may be a flexible band-shaped structure.

[0078] The device body 101 may include a frame (not shown in the figure), and the wearable device 100 may also include a structural device (not shown in the figure) for realizing the function of the device, and the structural device may be arranged in the frame. For example, taking the wearable device 100 as a watch, the frame of the device body 101 may also contain a movement.

[0079] Exemplarily, the movement can be a manual mechanical movement, an automatic mechanical movement or an intelligent movement, etc., and the type of movement is not limited in the embodiments of the present application. It is understandable that the device body 101 can be a structure in which the movement is assembled in the frame, or the device body 101 can also be unassembled with the movement, and the device body 101 can only include the frame.

[0080] Among them, in the example where the movement is an automatic mechanical movement or an intelligent movement, the movement may include a control unit, which can control the entire wearable device 100, such as controlling the display of information such as time and health monitoring indicators.

[0081] The movement may also include a battery and a wireless charging coil. The battery may be electrically connected to the control unit to supply power to the control unit. The wireless charging coil may be electrically connected to the battery to charge the battery through the wireless charging coil.

[0082] Exemplarily, the strap 102 may include a first strap body 21 and a second strap body 22 , and the first strap body 21 and the second strap body 22 may be connected to two ends of the device body 101 , respectively.

[0083] The first belt body 21 and the second belt body 22 can be matched in a convenient and detachable manner. Figure 1As shown, the first belt body 21 and the second belt body 22 can be assembled and connected together, so that the device body 101, the first belt body 21 and the second belt body 22 can together form a closed ring to surround the user's wrist or other wearing parts, thereby fixing the entire wearable device 100 on the user.

[0084] Figure 2 A schematic diagram of the structure of a wearable device when not worn provided in an embodiment of the present application.

[0085] Correspondingly, the first belt body 21 and the second belt body 22 can also be detached and separated, so that the first belt body 21 and the second belt body 22 can be separated, which is convenient for removing the wearable device 100 from the user.

[0086] It can be understood that in some examples, when the wearable device 100 is a wearable accessory such as a belt, a waistband, a bracelet, an anklet, or a ring, the wearable device 100 may not include the device body 101, and the strap 102 may be an integrated structural part. The two ends of the strap 102 may be a first strap body and a second strap body, respectively, so that the two ends of the strap 102 are connected in a convenient disassembly manner, so that the strap 102 can be together formed into a ring to surround the wearing part for wear.

[0087] In some examples, the wearable device 100 may also include a sensor (not shown in the figure), which can be used to implement any one or more of a variety of functions such as motion monitoring, heart rate monitoring, sleep monitoring, diet monitoring, blood pressure and blood oxygen monitoring. The health monitoring function of the wearable device 100 can be realized through the sensor.

[0088] It is understandable that the sensor can be set in the wearable device 100 according to the function and type of the sensor, and can meet the functional requirements of the sensor. For example, the sensor can be set on the strap 102, or the sensor can also be set on the frame of the device body 101.

[0089] The sensor may be an optical sensor such as a photoplethysmography (PPG) sensor. Of course, in some other examples, the sensor may also be other types of biosensors.

[0090] It should be noted that in the process of realizing the above-mentioned health function monitoring, the sensor of the wearable device 100 needs to be close to the user's wearing part (such as the wrist, etc.) to achieve continuous measurement and ensure accuracy. Therefore, the sensor can be located on the inner surface of the strap 102 or the frame of the device body 101. The inner surface of the strap 102 or the frame refers to the side of the strap 102 or the frame that faces the user's wearing part and contacts the user's wearing part when the wearable device 100 is worn.

[0091] It is understood that the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the wearable device 100. In other embodiments of the present application, the wearable device 100 may also include more or fewer components than shown in the figure, or combine certain components, or split certain components, or arrange the components differently. For example, the wearable device 100 may also include components such as a dial, a drive mechanism, a display panel, and a battery.

[0092] Figure 2a The present invention is a schematic diagram of the partial structure of the assembly of the first strap body and the second strap body of the strap in the related art.

[0093] Taking the wearable device as a watch as an example, the materials of the first strap body and the second strap body may include flexible materials. For example, the first strap body and the second strap body may be leather straps, rubber straps, and nylon straps.

[0094] In order to improve the convenience of wearing, the first strap body and the second strap body are usually matched in a buckle manner, and a common scheme is a horseshoe buckle and a buckle hole. For example, see Figure 2a As shown, a horseshoe buckle 300 may be provided on the end of the first strap 201 facing away from the device body. The horseshoe buckle 300 may include a buckle ring 301 and a buckle pin 302. The buckle ring 301 and the buckle pin 302 may be movably provided. For example, the buckle ring 301 and the buckle pin 302 may be rotatably provided on the first strap 201. A buckle hole 203 may be provided on the second strap 202.

[0095] When wearing the watch, the second strap 202 needs to be passed through the buckle 301 of the horseshoe buckle 300 first, and then one end of the pin 302 of the horseshoe buckle 300 needs to be passed through the buckle hole 203 on the second strap 202 and overlapped on the buckle 301, so as to realize the buckle connection between the first strap 201 and the second strap 202. When the watch needs to be removed, the second strap 202 needs to be pulled to separate the buckle hole 203 from the pin 302, and then the second strap 202 needs to be removed from the buckle 301, and the first strap 201 and the second strap 202 need to be separated. The wearing and removal methods are relatively cumbersome, and the user experience is poor.

[0096] Moreover, the watch strap of the horseshoe buckle type includes many parts, is more complex in shape, and has a higher manufacturing cost. The buckle 301 of the horseshoe buckle 300 is often rotatably set on the first belt body 201 by means of a shaft-hole match. For example, the first belt body 201 has an assembly hole (not shown in the figure) on the end facing away from the device body, and the shaft of the buckle 301 is rotatably set in the assembly hole. After the second belt body 202 passes through the buckle 301 and matches with the buckle hole 203, the second belt body 202 will have wrinkles and protrusions at the buckle 301 position, and there will also be a problem of scratching the hand at the position of the hard, columnar buckle shaft, which is not comfortable to wear and affects the user experience.

[0097] In addition, a common watch is usually provided with a watch band loop on the first band body, as shown in FIG. Figure 2a As shown, two strap loops may be provided on the first strap body 201, such as strap loop 401 and strap loop 402, respectively. The material of the strap loop is usually consistent with that of the first strap body 201 and the second strap body 202. After the second strap body 202 passes through the horseshoe buckle 300, it can be sequentially inserted into the strap loop 401 and the strap loop 402. The strap loop 401 and the strap loop 402 can play a role in closing and limiting the second strap body 202, so as to prevent the second strap body 202 from warping and affecting the user experience and aesthetics. It can be understood that when different wrist circumferences are worn, the length (length along the extension direction) of the second strap body 202 after passing through the buckle 301 is different. The strap loop is usually set on the first strap body 201, and at least one of the strap loops can be movably set, for example, the strap loop 402 can move along the extension direction of the first strap body 201 to match different wrist circumferences.

[0098] However, the movable strap ring is easy to fall off from the first strap body, affecting normal use. The flexible strap ring is also easy to break and has a limited service life, which will affect the service life and user experience of the wearable device.

[0099] Based on this, the embodiment of the present application provides a buckle structure and a buckle ring structure for a watchband of a wearable device, wherein the buckle assembly of the first belt body and the second belt body is realized by the base and the first clamping part of the buckle structure being buckled with the first buckle hole of the first belt body, and the first clamping part and the second clamping part of the buckle structure being buckled with the second buckle hole of the second belt body. When wearing the device, the buckle structure on the first belt body can be directly buckled with the second buckle hole on the second belt body. When removing the device, the buckle structure can be separated from the second buckle hole on the second belt body. The wearing and disassembly method is simple, the operation is convenient and fast, and the convenience and user experience are greatly improved. The buckle ring structure is buckled with the first buckle hole of the first belt body through the bottom wall and the third clamping part, so that the buckle ring structure can be assembled on the first belt body, avoiding the problem of the buckle ring structure falling off, ensuring the normal use of the watchband, and improving the user experience and service life.

[0100] Figure 3 A schematic diagram of the structure of the assembly connection between a first strap body and a second strap body in a watch strap provided in an embodiment of the present application.

[0101] See also Figure 3 As shown, the strap 102 includes a first strap body 21 and a second strap body 22, and the first strap body 21 and the second strap body 22 are respectively used to connect with the device body. For example, one end of the first strap body 21 can be connected to one end of the device body through a spring ear, and one end of the second strap body 22 can also be connected to the other end of the device body through a spring ear.

[0102] It is understandable that the first belt body 21, the second belt body 22 and the device body may be fixedly connected, or may be rotatably connected so that the first belt body 21 and the second belt body 22 can rotate relative to the device body.

[0103] The second belt body 22 and the first belt body 21 can be detachably connected by snap-fitting, that is, the first belt body 21 and the second belt body 22 can be snap-fitted together, so that the device body 101, the first belt body 21 and the second belt body 22 can together form a closed ring for wearing.

[0104] Figure 4 This is a schematic structural diagram of a watch strap provided in an embodiment of the present application in which a first strap body and a second strap body are separated.

[0105] See also Figure 4 As shown, the first belt body 21 and the second belt body 22 can also be detached from each other, so as to facilitate the removal of the wearable device from the user.

[0106] For example, to achieve the snap fit between the first belt body 21 and the second belt body 22, see Figure 4 As shown, the first belt body 21 has a first buckle hole 211. For example, the first belt body 21 may have a first surface 21b and a second surface 21a opposite to each other (see Figure 6 The first surface 21b of the first strap 21 may be the side of the first strap 21 facing and in contact with the user's skin when worn, and the second surface 21a is the side opposite to the first surface 21b. The first buckle hole 211 may be a through hole, and the first buckle hole 211 may pass through from the first surface 21b of the first strap 21 to the second surface 21a of the first strap 21.

[0107] In the embodiment of the present application, the thickness direction of the first belt body 21 and the second belt body 22 is as follows: Figure 4 As shown in the z direction in FIG. 1 , the first surface 21b and the second surface 21a may be two surfaces opposite to each other along the thickness direction of the first belt body 21. It should be noted that in the embodiment of the present application, the thickness of each structural component refers to the size of the structural component in the thickness direction.

[0108] The extending direction of the first belt body 21 and the second belt body 22 may be the length direction in which the first belt body 21 and the second belt body 22 are laid flat, such as Figure 4 In the x direction, when worn, the first belt body 21 and the second belt body 22 are bent, and the relative extending directions of the first belt body 21 and the second belt body 22 are also bent to surround the wrist.

[0109] There may be a plurality of first button holes 211, and the plurality of first button holes 211 may be arranged at intervals along the extension direction of the first belt body 21. Of course, in some other examples, there may also be one first button hole 211.

[0110] The second belt body 22 has a second buckle hole 221. Exemplarily, the second belt body 22 may have a third surface 22a and a fourth surface 22b opposite to each other. The third surface 22a and the fourth surface 22b may also be two opposite surfaces of the second belt body 22 along the thickness direction (z direction). The fourth surface 22b of the second belt body 22 may be a side of the second belt body 22 facing and in contact with the user's skin when worn, and the third surface 22a is a side opposite to the fourth surface 22b.

[0111] The second button hole 221 may also be a through hole. The second button hole 221 may pass through from the third surface 22 a of the second belt body 22 to the fourth surface 22 b of the second belt body 22 .

[0112] The number of the second button hole 221 may also be multiple, and the multiple second button holes 221 may be arranged at intervals along the extension direction of the second belt body 22. Of course, in some other examples, the number of the second button hole 221 may be one.

[0113] Combination Figure 3 and Figure 4 As shown, the strap 102 also includes a buckle structure 40, which is detachably connected to the first strap body 21 and the second strap body 22, that is, the buckle structure 40 is connected to the first strap body 21 in a convenient and detachable manner, and the buckle structure 40 is also connected to the second strap body 22 in a portable and detachable manner, thereby realizing a detachable connection between the first strap body 21 and the second strap body 22 through the buckle structure 40.

[0114] Figure 5 for Figure 4 Schematic diagram of the structure of the middle buckle body.

[0115] See also Figure 5 As shown, the buckle body structure 40 may include a base 41, a first clamping portion 422 and a second clamping portion 432. The first clamping portion 422 and the second clamping portion 432 may be fixed on the base 41 respectively.

[0116] Figure 6 for Figure 3 A schematic cross-sectional view of the assembly connection between the first strap body and the second strap body of the middle strap.

[0117] Combination Figure 6As shown, the base 41 and the first snap-fit ​​portion 422 can be snap-fitted with the first buckle hole 211 of the first belt body 21, so that the buckle body structure 40 and the first belt body 21 are assembled and fixed together in a detachable snap-fit ​​manner.

[0118] The first snap-fitting portion 422 and the second snap-fitting portion 432 can be snap-fitted with the second buckle hole 221 of the second belt body 22, so that the buckle body structure 40 and the second belt body 22 can also be assembled and fixed together in a detachable snap-fitting manner.

[0119] That is, the buckle body structure 40 can be assembled and fixed together by snap-fitting the base 41 and the first snap-fitting portion 422 with the first buckle hole 211 of the first belt body 21. The buckle body structure 40 can also be assembled and fixed together by snap-fitting the first snap-fitting portion 422 and the second snap-fitting portion 432 with the second buckle hole 221 of the second belt body 22, so that the first belt body 21 and the second belt body 22 are assembled and connected together.

[0120] The base 41 and the first clamping portion 422 of the buckle structure 40 can also be disengaged from the first buckle hole 211, and the first clamping portion 422 and the second clamping portion 432 of the buckle structure 40 can also be disengaged from the second buckle hole 221, so that the first belt body 21 and the second belt body 22 are separated.

[0121] In actual use, the buckle structure 40 can be assembled on one of the first strap 21 and the second strap 22. When wearing or removing the watch strap 102, the buckle structure 40 can be assembled or disassembled with the other of the first strap 21 and the second strap 22. For example, the buckle structure 40 is buckled and set on the first buckle hole 211 of the first strap 21 through the base 41 and the first clamping portion 422 (refer to Figure 4 When worn, the first snap-fitting portion 422 and the second snap-fitting portion 432 of the buckle structure 40 can be snapped into the second buckle hole 221 of the second strap 22, so that the first strap 21 and the second strap 22 can be assembled and connected together. When removing the watch strap 102, the buckle structure 40 can be separated from the second buckle hole 221 of the second strap 22.

[0122] That is, when wearing the device, the buckle structure 40 on the first strap body 21 can be directly buckled with the second buckle hole 221 on the second strap body 22. When removing the device, the buckle structure 40 can be separated from the second buckle hole 221 on the second strap body 22. The wearing and removal methods are simple, the operation is convenient and quick, and the convenience and user experience are greatly improved.

[0123] The detachable cooperation between the buckle structure 40 and the first belt body 21 and the detachable cooperation between the buckle structure 40 and the second belt body 22 makes the assembly flexibility of the buckle structure 40 on the first belt body 21 and the second belt body 22 high, and the applicable scenes are more abundant, meeting the various wearing needs of users. For example, in actual use, the buckle structure 40 can also be snap-fitted on the second belt body 22. When wearing or removing the device, the buckle structure 40 can be snap-fitted or separated from the first buckle hole 211 of the first belt body 21, and the assembly design is flexible.

[0124] In addition, when there are multiple first buckle holes 211 on the first strap body 21 and multiple second buckle holes 221 on the second strap body 22, the buckle body structure 40 can cooperate with any one of the first buckle holes 211 and the second buckle holes 221, so that the position of the buckle body structure 40 on the first strap body 21 and the second strap body 22 can be flexibly adjusted to meet the needs of wearing with different wrist circumferences, improve wearing comfort, and meet different wearing needs.

[0125] In the embodiment of the present application, the buckle structure 40 is buckled and assembled on the first belt body 21, and when wearing or removing the device, the buckle structure 40 is buckled or separated from the second belt body 22 as an example for description.

[0126] Figure 7 for Figure 6 A magnified view of the local structure of part A.

[0127] For example, the first clamping portion 422 may be disposed on one side of the base 41 (see Figure 5 As shown), when the buckle structure 40 is buckled with the first belt body 21, see Figure 7 As shown, the base 41 can be abutted against the first surface 21b of the first belt body 21, the first clamping portion 422 can pass through the first buckle hole 211 of the first belt body 21, and the first clamping portion 422 can be abutted against the second surface 21a of the first belt body 21. By abutting the base 41 with the first surface 21b of the first belt body 21, the first clamping portion 422 and the second surface 21a of the first belt body 21, the buckle structure 40 and the first belt body 21 are fixedly limited, so that the buckle structure 40 is buckled and set on the first belt body 21. The buckle matching design is simple, easy to implement and has a low manufacturing cost.

[0128] The second clamping portion 432 may be located on the side of the first clamping portion 422 facing away from the base 41, that is, the base 41, the first clamping portion 422 and the second clamping portion 432 may be sequentially distributed along the thickness direction, and the second clamping portion 432 may pass through the first buckle hole 211 and protrude on the second surface 21a of the first belt body 21 (refer to Fig.12That is to say, when the buckle structure 40 is assembled with the first belt body 21, the second clamping portion 432 and the first clamping portion 422 can pass through the first buckle hole 211 in sequence, so that the base 41 abuts against the first surface 21b of the first belt body 21, and the first clamping portion 422 abuts against the second surface 21a of the first belt body 21, and the first clamping portion 422 and the second clamping portion 432 can both protrude from the second surface 21a of the first belt body 21.

[0129] See also Figure 7 As shown, when worn, the second clamping portion 432 can pass through the second buckle hole 221 on the second strap body 22 and abut against the third surface 22a of the second strap body 22. At this time, the first clamping portion 422 can abut against the fourth surface 22b of the second strap body 22. Through the abutment between the first clamping portion 422 and the fourth surface 22b of the second strap body 22, and the second clamping portion 432 and the third surface 22a of the second strap body 22, the buckle body structure 40 and the second strap body 22 are fixedly limited, so that the buckle body structure 40 is buckled and set on the second strap body 22, thereby realizing the buckle fit of the first strap body 21 and the second strap body 22. The buckle fit is simple in design, easy to implement and has low manufacturing cost.

[0130] Among them, continue to see Figure 7 As shown, the gap between the first clamping portion 422 and the base 41 along the thickness direction may be greater than or equal to the thickness of the first belt body 21, wherein the gap between the first clamping portion 422 and the base 41 is, in the thickness direction, the distance from one side of the first clamping portion 422 facing the base 41 to one side of the base 41 facing the first clamping portion 422, which may also be understood as an air gap between the first clamping portion 422 and the base 41.

[0131] That is, in the thickness direction, the gap between the first clamping portion 422 and the base 41 can be greater than or equal to the gap between the first surface 21b and the second surface 21a of the first belt body 21, so that after the first clamping portion 422 passes through the first buckle hole 211, the base 41 and the first clamping portion 422 can respectively abut against the first surface 21b and the second surface 21a, which facilitates the assembly operation, reduces the difficulty of assembly, and improves the convenience of assembly.

[0132] Correspondingly, the gap between the second clip part 432 and the first clip part 422 along the thickness direction can be greater than or equal to the thickness of the second belt body 22. The gap between the second clip part 432 and the first clip part 422 is, in the thickness direction, the distance from the side of the second clip part 432 facing the base 41 to the side of the first clip part 422 facing away from the base 41, which can also be understood as the air gap between the first clip part 422 and the second clip part 432.

[0133] That is, in the thickness direction, the gap between the first clamping portion 422 and the second clamping portion 432 can be greater than or equal to the gap between the third surface 22a and the fourth surface 22b of the second belt body 22, so that after the second clamping portion 432 passes through the second buckle hole 221, the first clamping portion 422 and the second clamping portion 432 can respectively abut against the fourth surface 22b and the third surface 22a, which facilitates the assembly operation, reduces the difficulty of assembly, and improves the convenience of assembly.

[0134] In the thickness direction, Figure 7 As shown in the figure, the thickness of the base 41 can be less than the thickness of the second clip part 432. On the one hand, the thickness of the second clip part 432 can be relatively thick, so that the second clip part 432 is not easy to fall out of the second buckle hole 221 in the wearing scenario, reducing or avoiding the risk of the first belt body 21 and the second belt body 22 falling off and separating.

[0135] On the other hand, it can be understood that the base 41 is in contact with the first surface 21b of the first strap 21. When worn, the base 41 is located between the user's skin and the first surface 21b, so that the thickness of the base 41 can be relatively small, reducing or avoiding the problem of scratching the hand due to the thick base 41, and facilitating the side of the strap 102 facing the user to be a relatively smooth curved surface when worn (refer to Figure 1 Improve wearing comfort.

[0136] Among them, continue to see Figure 7 As shown, the side of the base 41 facing away from the first clamping portion 422 can be flat, which further reduces or avoids the problem of the base 41 scratching the hand and improves wearing comfort.

[0137] The thickness of the first clamping portion 422 may also be less than the thickness of the second clamping portion 432. It is understood that the first clamping portion 422 abuts against the second surface 21a of the first belt body 21 and the fourth surface 22b of the second belt body 22, respectively. Figure 7 As shown in the figure, the first clamping portion 422 is located between the first belt body 21 and the second belt body 22. The first clamping portion 422 has a smaller thickness, and the first belt body 21 and the second belt body 22 can fit better after being buckled together, reducing or avoiding wrinkles, bulges, etc. at the position of the buckle body structure 40, which is further conducive to improving the wearing comfort.

[0138] Continue to see Figure 7 As shown, the second clamping portion 432 may include an arcuate wall surface 433, and the arcuate wall surface 433 may be annular (combined with Figure 5As shown in the figure, the arcuate wall surface 433 can extend from one end of the second clamping portion 432 away from the base 41 to the end of the second clamping portion 432 adjacent to the base 41, and the arcuate wall surface 433 can be arranged around the end surface of the second clamping portion 432 away from the base 41, and the end surface can be a plane, so that the entire outer wall surface of the second clamping portion 432 is formed by a plane and an arcuate surface, which is relatively smooth and rounded, which is conducive to improving the aesthetics and safety, and avoiding the second clamping portion 432 protruding on the third surface 22a of the second belt body 22 from causing scratches to the user.

[0139] From one end of the second clamping portion 432 away from the base 41 to the end of the second clamping portion 432 adjacent to the base 41, the outer contour size of the arcuate wall surface 433 can gradually increase, that is, the circumferential length of the arcuate wall surface 433 gradually increases, so that the second clamping portion 432 can be in the shape of a mushroom head, so that the second clamping portion 432 can be easier to pass through the second buckle hole 221 and abut against the third surface 22a of the second strap body 22, which is easy to operate and helps to improve the wearing convenience of the watch strap.

[0140] The buckle body structure 40 may also include a first connecting portion 421 and a second connecting portion 431. The first connecting portion 421 may be located between the first clamping portion 422 and the base 41 (combined with the first clamping portion 422). Figure 5 As shown), the first clamping portion 422 can be fixed to the base 41 through the first connecting portion 421.

[0141] The second connecting portion 431 may be located between the second clamping portion 432 and the first clamping portion 422 , so that the second clamping portion 432 may be fixed to the first clamping portion 422 via the second connecting portion 431 .

[0142] The base 41, the first connecting part 421, the first clamping part 422, the second connecting part 431 and the second clamping part 432 can be distributed and connected in sequence along the thickness direction, so that the buckle body structure 40 as a whole can be a nail-shaped buckle part with a simple structural design and relatively small size, which reduces or avoids the impact of the buckle body structure 40 setting on the user's wearing comfort and has high aesthetics.

[0143] Continue to see Figure 7 As shown, it can be understood that when the buckle body structure 40 is assembled with the first belt body 21, the base 41 and the first clamping portion 422 respectively abut against the first surface 21b and the second surface 21a of the first belt body 21, and the first connecting portion 421 can be inserted into the first buckle hole 211.

[0144] When the buckle structure 40 is assembled with the second belt body 22 , the first clamping portion 422 and the second clamping portion 432 abut against the fourth surface 22 b and the third surface 22 a of the second belt body 22 , respectively, and the second connecting portion 431 can be inserted into the second buckle hole 221 .

[0145] For example, the outer contour size of the base 41 may be larger than the outer contour size of the first clamping portion 422 (combined with Figure 8 As shown), in the embodiment of the present application, the outer contour size of each structural component can be the size of the projection area formed by the vertical projection along the thickness direction, and can also be understood as the maximum outer diameter size of each structural component.

[0146] The outer contour size of the base 41 is made larger than the outer contour size of the first clamping portion 422, and the first clamping portion 422 can pass through the first buckle hole 211, ensuring that the base 41 cannot pass through the first buckle hole 211, and abuts against the first surface 21b of the first belt body 21, thereby ensuring the buckle fit strength between the buckle body structure 40 and the first belt body 21, and improving the stability of the assembly and fixation of the buckle body structure 40 and the first belt body 21.

[0147] Correspondingly, the outer contour size of the base 41 may also be larger than the outer contour size of the second clamping portion 432 , and the second clamping portion 432 may pass through the first buckle hole 211 and protrude from the first surface 21 b of the first belt body 21 .

[0148] The outer contour size of the first clamping portion 422 may be larger than the outer contour size of the second clamping portion 432 (combined with Figure 8 As shown in the figure, the second clamping portion 432 can conveniently pass through the second buckle hole 221 of the second strap 22 and abut against the third surface 22a, and the first clamping portion 422 is not convenient to pass through the second buckle hole 221, and can abut against the fourth surface 22b, thereby improving the assembly stability of the first strap 21 and the second strap 22, and facilitating the buckling and separation of the second clamping portion 432 and the second buckle hole 221, thereby realizing the assembly and separation and disassembly of the first strap 21 and the second strap 22, making the operation more convenient, and improving the wearing convenience of the watch strap.

[0149] The outer contour size of the first connecting portion 421 can be smaller than that of the first clamping portion 422 to ensure that the first clamping portion 422 abuts against the second surface 21a of the first belt body 21 after passing through the first buckle hole 211, while the first connecting portion 421 is accommodated in the first buckle hole 211.

[0150] The outer contour size of the first connecting portion 421 can also be slightly larger than the inner diameter size of the first buckle hole 211, so that the first connecting portion 421 and the first buckle hole 211 can have an interference fit, further improving the snap-fit ​​strength between the buckle body structure 40 and the first buckle hole 211, and improving the assembly stability of the buckle body structure 40 on the first belt body 21.

[0151] Of course, in some examples, the outer contour size of the first connecting portion 421 may also be smaller than or equal to the inner diameter size of the first buckle hole 211 .

[0152] Accordingly, the outer contour size of the second connecting portion 431 can be smaller than the outer contour size of the second clamping portion 432, ensuring that the second clamping portion 432 abuts against the third surface 22a of the second belt body 22 after passing through the second buckle hole 221, while the second connecting portion 431 is accommodated in the second buckle hole 221.

[0153] The outer contour size of the second connecting portion 431 can also be slightly larger than the inner diameter size of the second buckle hole 221, so that the second connecting portion 431 and the second buckle hole 221 can have an interference fit, further improving the snap-fitting strength between the buckle body structure 40 and the second buckle hole 221, improving the stability of the snap-fitting of the first belt body 21 and the second belt body 22, and reducing or avoiding the risk of the first belt body 21 and the second belt body 22 falling off and separating during assembly and use.

[0154] Figure 8 for Figure 5 Schematic diagram of the top view of the middle buckle body structure.

[0155] For example, in some examples, see Figure 8 As shown, the vertical projections of the first clamping portion 422 and the first connecting portion (not shown) on the base 41 along the thickness direction can be completely located inside the base 41, so that the outer contour size of the first clamping portion 422 can be smaller than the outer contour size of the base 41.

[0156] The vertical projection of the first connecting portion along the thickness direction on the base 41 can be completely located within the vertical projection of the first clamping portion 422 along the thickness direction on the base 41 , so that the outer contour size of the first connecting portion is smaller than the outer contour size of the first clamping portion 422 .

[0157] The projections of the second clamping portion 432 and the second connecting portion (not shown in the figure) on the base 41 along the thickness direction can be completely located on the projection of the first clamping portion 422 on the base 41 along the thickness direction, so that the outer contour size of the second clamping portion 432 is smaller than the outer contour size of the first clamping portion 422.

[0158] The vertical projection of the second connecting portion along the thickness direction on the base 41 can be completely located within the vertical projection of the second clamping portion 432 along the thickness direction on the base 41 , so that the outer contour size of the second connecting portion is smaller than the outer contour size of the second clamping portion 432 .

[0159] The molding material of the buckle structure 40 may include a hard material, for example, the molding material of the buckle structure 40 may include metal, plastic, etc. The buckle structure 40 has a high strength, and it is easy for the buckle structure 40 to be buckled with the first buckle hole 211 of the first belt body 21 and the second buckle hole 221 of the second belt body 22, respectively, for easy operation.

[0161] See also Fig. 9 As shown, the watchband 102 may further include a buckle structure 30, and the buckle structure 30 may also be assembled on the first strap body 21 in a convenient and detachable manner. The buckle structure 30 may be an annular structural member with a cavity inside, and the buckle structure 30 may be arranged around the first strap body 21, and the buckle structure 30 may also be assembled on the first strap body 21 in a snap-fit ​​manner.

[0162] Fig.10 for Figure 3 A schematic front view of the partial structure of the assembly connection between the first strap body and the second strap body of the middle strap.

[0163] See also Fig.10 As shown, when the second belt body 22 and the first belt body 21 are assembled and connected, the second belt body 22 can be inserted into the buckle structure 30, and the buckle structure 30 can play a role in closing and limiting the second belt body 22 to prevent the second belt body 22 from warping, bending, etc. and affecting the user experience and aesthetics.

[0164] That is, when the wearable device is worn, the second belt body 22 and the first belt body 21 can be buckled together through the buckle structure 40 , and the second belt body 22 can be inserted into the buckle structure 30 .

[0165] When the wearable device 100 needs to be removed, the second belt body 22 can be removed from the buckle structure 30, and then the second belt body 22 can be separated from the buckle structure 40, thereby separating the second belt body 22 from the first belt body 21. The wearing and removing method is extremely simple and easy to operate, which significantly improves the convenience of wearing and use.

[0166] Of course, in some examples, when wearing or removing, the second strap 22 may first be passed through the buckle structure 30 or removed from the buckle structure 30 , and then the second strap 22 may be snap-fitted or separated from the buckle structure 40 .

[0167] The buckle structure 40 may be disposed on the first belt body 21, that is, the buckle structure 40 and the buckle ring structure 30 are both located on the first belt body 21. Alternatively, in some examples, the buckle structure 40 may also be disposed on the second belt body 22, that is, the buckle structure 40 and the buckle ring structure 30 may be located on the second belt body 22 and the first belt body 21, respectively.

[0168] In the embodiment of the present application, the buckle structure 40 and the buckle ring structure 30 are both located on the first belt body 21 for description.

[0169] It should be noted that the number of the buckle ring structure 30 can be one, or can also be multiple. Correspondingly, the number of the buckle body structure 40 can also be one, or can also be multiple, which can be selected and set according to actual needs.

[0170] Fig.11 for Figure 4 Schematic diagram of the structure of the middle buckle structure.

[0171] See also Fig.11 As shown, the buckle structure 30 may include a bottom wall 31 and a top wall 32 . The bottom wall 31 and the top wall 32 may be arranged opposite to each other, and there is a gap between the bottom wall 31 and the top wall 32 to form a cavity inside the buckle structure 30 .

[0172] A protruding third clamping portion 342 may be provided on the inner surface of the bottom wall 31 , wherein the inner surface of the bottom wall 31 refers to a side of the bottom wall 31 facing the inner cavity, that is, a side of the bottom wall 31 facing the top wall 32 .

[0173] Fig.12 for Figure 4 An enlarged view of the cross-sectional local structure of the first strap body in the strap at the buckle body structure and the buckle ring structure.

[0174] The buckle structure 30 is wrapped around the first belt body 21, see Fig.12 As shown, the inner surface of the bottom wall 31 can be abutted against the first surface 21b of the first strap 21. The third clamping portion 342 can pass through the first buckle hole 211 of the first strap 21 and abut against the second surface 21a of the first strap 21. In this way, the buckle structure 30 and the first strap 21 can be fixed by the abutment between the bottom wall 31 and the first surface 21b of the first strap 21, the third clamping portion 342 and the second surface 21a of the first strap 21, so that the buckle structure 30 can be buckled and assembled on the first strap 21 through the first buckle hole 211, avoiding the problem of the buckle structure 30 falling off, ensuring the normal use of the watchband 102, and improving the use experience and service life. In addition, the buckle structure 30 is buckled and assembled on the first strap 21 through the buckle cooperation between the third clamping portion 342 and the first buckle hole 211, and the structure design is simple, easy to implement and conducive to reducing costs.

[0175] A gap can be formed between the top wall 32 and the second surface 21a of the first belt body 21 for the second belt body 22 to pass through. In this way, when wearing, the bottom wall 31 of the buckle structure 30 contacts the user, and the second belt body 22 is located on the side of the bottom wall 31 facing the top wall 32 (refer to Figure 7 As shown), the two straps 102 can be naturally matched, reducing or avoiding the formation of wrinkles and bulges at the position of the buckle structure 30, thereby reducing or avoiding the problem of the buckle structure 30 scratching the hand and improving wearing comfort.

[0176] The side of the bottom wall 31 facing away from the top wall 32 may be a flat surface, which further reduces the wrinkles and protrusions at the buckle structure 30, and is more conducive to forming a relatively smooth arc surface on the side of the strap facing the user (refer to Figure 1 Improve wearing comfort.

[0177] The buckle structure 30 may further include two arc-shaped side walls 33 (see Fig.11 As shown), the two arcuate side walls 33 may also be arranged opposite to each other, and the two arcuate side walls 33 are respectively located on both sides of the bottom wall 31 and the top wall 32, and the two ends of each arcuate side wall 33 are respectively connected to the bottom wall 31 and the top wall 32, so that the bottom wall 31, the top wall 32 and the arcuate side walls 33 form a closed ring.

[0178] The buckle structure 30 is a closed annular structure, which can improve the stability of the buckle structure 30 on the end limit of the second belt body, better constrain the second belt body, and improve the wearing comfort and aesthetics. In addition, the arc-shaped side wall 33 has a good smooth transition, reducing or avoiding the corners of the buckle structure 30 from scratching the user.

[0179] Combination Fig.11 and Fig.12 As shown, the buckle structure 30 may further include a third connecting portion 341 , which may be located between the inner surface of the bottom wall 31 and the third clamping portion 342 , and the third clamping portion 342 may be connected and fixed to the bottom wall 31 via the third connecting portion 341 .

[0180] It is understandable that when the buckle structure 30 is assembled with the first belt body 21 , the bottom wall 31 and the third clamping portion 342 respectively abut against the first surface 21 b and the second surface 21 a of the first belt body 21 , and the third connecting portion 341 can be inserted into the first buckle hole 211 .

[0181] For example, see Fig.12 As shown, the gap between the third clamping portion 342 and the inner surface of the bottom wall 31 along the thickness direction is greater than or equal to the thickness of the first belt body 21, wherein the gap between the third clamping portion 342 and the inner surface of the bottom wall 31 is, in the thickness direction, the distance from the side of the third clamping portion 342 facing away from the top wall 32 to the inner surface of the bottom wall 31, which can also be understood as the air gap between the third clamping portion and the bottom wall 31.

[0182] That is, in the thickness direction, the gap between the third clamping portion 342 and the inner surface of the bottom wall 31 can be greater than or equal to the gap between the first surface 21b and the second surface 21a of the first belt body 21, so that after the third clamping portion 342 passes through the first buckle hole 211, the bottom wall 31 and the third clamping portion 342 can respectively abut against the first surface 21b and the second surface 21a, which facilitates the assembly operation, reduces the difficulty of assembly, and improves the convenience of assembly.

[0183] The outer contour size of the third clamping portion 342 can be smaller than the outer contour size of the bottom wall 31. The third clamping portion 342 can pass through the first buckle hole 211 to ensure that the bottom wall 31 cannot pass through the first buckle hole 211, and abut against the first surface 21b of the first belt body 21, thereby ensuring the buckle fit strength between the buckle structure 30 and the first belt body 21 and improving the stability of the assembly and fixation of the buckle structure 30 and the first belt body 21.

[0184] The outer contour size of the third connecting portion 341 can be smaller than that of the third clamping portion 342 to ensure that the third clamping portion 342 abuts against the second surface 21a of the first belt body 21 after passing through the first buckle hole 211, while the third connecting portion 341 is accommodated in the first buckle hole 211.

[0185] The outer contour size of the third connecting portion 341 can be slightly larger than the inner diameter size of the first buckle hole 211, so that the third connecting portion 341 and the first buckle hole 211 can have an interference fit, further improving the snap-fit ​​strength between the buckle structure 30 and the first buckle hole 211, and improving the assembly stability of the buckle structure 30 on the first belt body 21.

[0186] Of course, in some examples, the outer contour size of the third connecting portion 341 may also be smaller than or equal to the inner diameter size of the first buckle hole 211 .

[0187] Among them, the molding material of the buckle structure 30 can also include hard materials, so that the buckle structure 30 has better hardness and strength, reducing or avoiding the risk of breakage of the buckle structure 30, extending the service life of the strap, and improving the user experience.

[0188] For example, the molding material of the buckle structure 30 may also include metal, plastic, etc. The molding materials of the buckle structure 30 and the buckle body structure 40 may be the same, or may be different.

[0189] Of course, in some examples, the molding material of the buckle structure 30 may also include a flexible material. For example, the buckle structure 30 may be a leather ring, a rubber ring, a nylon ring, etc.

[0190] Fig.13 for Figure 4 A schematic structural diagram from another viewing angle when the first strap body and the second strap body of the middle strap are separated.

[0191] It should be noted that see Fig.13As shown, when the first belt body 21 has a plurality of first buckle holes 211 and the second belt body 22 has a plurality of second buckle holes 221, the buckle structure 30 can be snap-fitted with any first buckle hole 211 on the first belt body 21, that is, the buckle structure 30 can be snap-fitted to any first buckle hole 211 of the first belt body 21, and the buckle structure 30 can also be removed from any first buckle hole 211.

[0192] In this way, the position of the buckle structure 30 on the first belt body 21 can be freely adjusted, so that the buckle structure 30 can be flexibly assembled on the first belt body 21 along the extension direction of the first belt body 21 to meet different wrist circumference requirements and usage requirements. That is, under the condition that the buckle structure 30 can be moved along the extension direction of the first belt body 21 to match different wrist circumference requirements, the buckle structure 30 is stably assembled on the first belt body 21.

[0193] For example, Fig.13 As shown in the figure, taking two of the first buckle holes 211 on the first strap 21 as an example, such as the first buckle hole 211a and the first buckle hole 211b respectively, the buckle structure 30 can be buckled on the first buckle hole 211a. When it is necessary to match a smaller wrist circumference, the buckle structure 30 can be removed from the first buckle hole 211a and buckled on the first buckle hole 211b.

[0194] Correspondingly, the buckle body structure 40 can also be snap-fitted with any first buckle hole 211, and the buckle body structure 40 can also be removed from any first buckle hole 211, that is, the position of the buckle body structure 40 on the first belt body 21 can also be freely adjusted, so that the buckle body structure 40 can also be flexibly assembled on the first belt body 21 along the extension direction of the first belt body 21, with a high degree of assembly freedom and flexibility, meeting different assembly and usage requirements.

[0195] The buckle structure 40 can also be snap-fitted with any second buckle hole 221. When the buckle structure 40 is matched with the second buckle holes 221 at different positions on the second strap body 22, the lengths of the strap 102 formed by the first strap body 21 and the second strap body 22 are different. The length of the strap 102 can be adjusted to meet the matching requirements of different wrist circumferences and improve wearing comfort.

[0196] It is understandable that when the buckle structure 40 cooperates with the first buckle holes 211 at different positions on the first strap body 21 , the length of the strap 102 can also be adjusted.

[0197] The position of the buckle structure 40 on the first belt body 21 can be adjusted by snapping together with different first buckle holes 211, and the position of the buckle structure 30 on the first belt body 21 can also be adjusted by snapping together with different first buckle holes 211. The positions of the buckle structure 40 and the buckle structure 30 on the first belt body 21 can be freely adjusted according to the wearing comfort of the user, and even the positions of the buckle structure 40 and the buckle structure 30 can be swapped, which has a high degree of design freedom and flexibility.

[0198] Exemplarily, the buckle structure 40 can be snap-fitted with any first buckle hole 211 on the first strap 21, and the buckle ring structure 30 can also be snap-fitted with any first buckle hole 211 on the first strap 21. The positions of the buckle structure 40 and the buckle ring structure 30 on the first strap 21 can be interchanged. For example, the buckle structure 40 can be closer to the end of the first strap 21 connected to the device body 101, and the buckle ring structure 30 can be farther away from the end of the first strap 21 connected to the device body 101. Alternatively, the buckle structure 40 can be farther away from the end of the first strap 21 connected to the device body 101, and the buckle ring structure 30 can be closer to the end of the first strap 21 connected to the device body 101.

[0199] Fig.14 for Figure 3 A schematic structural diagram of another viewing angle showing the assembly connection between the first strap body and the second strap body of the middle strap.

[0200] In addition, combined Fig.13 and Fig.14 As shown, the position of the buckle structure 40 on the first belt body 21 can be moved and adjusted (as shown by the arrow in the figure), and the position of the buckle structure 30 on the first belt body 21 can also be moved and adjusted (as shown by the arrow in the figure), so the relative positions of the buckle structure 40 and the buckle structure 30 on the first belt body 21 can be adjusted. Therefore, the positions of the buckle structure 40 and the buckle structure 30 can be reasonably adjusted. Fig.14 As shown, if the buckle structure 40 and the buckle ring structure 30 are kept at a relatively large distance (along the extension direction of the first strap body 21), when the second strap body 22 is inserted into the buckle ring structure 30 after being snap-fitted with the buckle structure 40 to close the second strap body 22, the second strap body 22 can be smoothly inserted into the buckle ring structure 30 without bulging, thereby avoiding the risk of nail breakage caused by the second strap body 22 being separated from the buckle structure 40 due to the bulging of the second strap body 22, thereby providing a better closing experience.

[0201] It is understandable that when a user initially wears the wearable electronic device, the buckle assembly position of the buckle structure 40 and the buckle ring structure 30 on the first belt body 21 can be adjusted to meet the user's wearing needs and avoid risks such as broken nails. After adjusting it into place once, the same user does not need to adjust it again when wearing it subsequently.

[0202] Of course, when different users wear the same device, due to differences in wrist circumference and wearing requirements, the positions of the buckle body structure 40 and the buckle ring structure 30 can be adjusted to match different requirements.

[0203] In addition, the first belt body 21 and the second belt body 22 have a first button hole 211 and a second button hole 221, respectively, and the first button hole 211 and the second button hole 221 are respectively used to snap-fit ​​with the button body structure 40, and the first button hole 211 is also used to snap-fit ​​with the buckle structure 30. In some examples, the structures of the first button hole 211 and the second button hole 221 can be the same, so that the structures of the first belt body 21 and the second belt body 22 can also be the same.

[0204] That is, the shape and structure of the first belt body 21 and the second belt body 22 can be completely the same (refer to Fig. 9 As shown in FIG. 1 , the shapes and distribution of the first buckle hole 211 on the first strap body 21 and the second buckle hole 221 on the second strap body 22 can be the same, so that the first strap body 21 and the second strap body 22 can be formed by the same structural type mold, reducing the number of different types of molds. In addition, a watch strap 102 can be formed by a buckle structure 30, a buckle body structure 40 and two strap bodies (the first strap body 21 and the second strap body 22) of the same shape, and the parts constituting the watch strap are greatly reduced, which can significantly reduce the cost and molding difficulty of the entire watch strap.

[0205] The molding materials of the first belt body 21 and the second belt body 22 may include flexible materials. For example, the first belt body 21 and the second belt body 22 may be leather belt bodies, rubber belt bodies and nylon belt bodies, which have higher flexibility and wearing comfort.

[0206] In addition, the first strap body 21 and the second strap body 22 include flexible materials, which can give the first buckle hole 211 and the second buckle hole 221 a certain degree of flexible deformation ability, so that the first clamping part and the second clamping part of the buckle body structure 40 pass through the first buckle hole 211 and abut against the first strap body 21 and the second strap body 22, and the third clamping part of the buckle structure 30 passes through the first buckle hole 211 and abuts against the first strap body 21, so as to facilitate the buckle assembly operation.

[0207] It should be noted that the strap 102 in the embodiment of the present application includes the first strap 21, the second strap 22, the buckle structure 40 and the buckle ring structure 30. Of course, in some other examples, the strap 102 may also only include the first strap 21, the second strap 22 and the buckle structure 40, and the first strap 21 and the second strap 22 may be snap-fitted by the buckle structure 40. The strap 102 may also include an annular structure for realizing the folding and limiting of the second strap 22, such as the strap ring 402 commonly used in the related art (see Figure 2aAlternatively, the strap 102 may not include a structural member for achieving the folding and limiting of the second strap body 22.

[0208] Alternatively, in some examples, the strap 102 may also only include the first strap 21, the second strap 22 and the buckle structure 30, and the second strap 22 is inserted into the buckle structure 30 to collect and limit the second strap 22. The first strap 21 and the second strap 22 may be assembled by other types of snap-fitting methods, such as the first strap 21 and the second strap 22 may be snap-fitted by a horseshoe buckle 300 commonly used in the related art, or the first strap 21 and the second strap 22 may be snap-fitted by other snap-fitting parts.
