Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0039] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "installed," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components.

[0040] refer to Figure 1The present invention provides a watchband connection structure 10 that is easy to assemble and disassemble, including a first fastener 100 and a second fastener 200. The first fastener 100 is used to connect the first watchband, and the second fastener 200 is used to connect the second watchband. During the assembly process of the watchband connection structure 10, it is only necessary to align the first fastener 100 and the second fastener 200 to achieve the connection and fixation of the first watchband and the second watchband; the user can also simply press and unlock to move the first fastener 100 and the second fastener 200 relatively away from each other, thereby achieving the disconnection of the first watchband and the second watchband. Here, the watchband connection structure 10, the first watchband, and the second watchband are combined to form a wearable device (not shown in the figure), which is used by the user to connect to the watch body to complete the wearing of the electronic watch. It should be noted that the watchband connection structure 10 of the present application, as a connection structure, can be applied not only to the field of watchband connection technology, but also to the connection and disconnection of wearable devices such as belts, wristbands, and collars, so as to achieve the wearing and carrying of various electronic devices.

[0041] refer to Figure 2 The first fastener 100 is provided with an installation cavity 110, and the second fastener 200 has a locking portion 210. The second fastener 200 can move relative to the first fastener 100 so that the locking portion 210 is engaged with or disengaged from the installation cavity 110, thereby realizing the connection or disconnection between the first fastener 100 and the second fastener 200.

[0042] Combined with reference Figure 2 and Figure 3 The watchband connection structure 10 further includes an unlocking member 300 and an elastic member 400. Two unlocking members 300 are movably connected to opposite sides of the first fastener 100, and the elastic member 400 is disposed between the unlocking member 300 and the first fastener 100. The unlocking member 300 partially extends into the mounting cavity 110 and is restrained relative to the engaging portion 210 to prevent the engaging portion 210 from disengaging from the mounting cavity 110, thereby connecting the first fastener 100 and the second fastener 200. Operating the unlocking member 300 releases the restraint between the unlocking member 300 and the engaging portion 210, allowing the engaging portion 210 to disengage from the mounting cavity 110 and allowing the second fastener 200 to move away from the first fastener 100, disconnecting and separating the second fastener 200 from the first fastener 100. In addition, the elastic member 400 is located in the mounting cavity 110. When the user operates the unlocking member 300, the elastic member 400 accumulates elastic force; when the user releases the unlocking member 300, the elastic member 400 releases the elastic force and simultaneously drives the unlocking member 300 to reset to the relative limit position between the unlocking member 300 and the locking portion 210. The elastic force of the elastic member 400 can maintain the relative limit state between the unlocking member 300 and the locking portion 210.

[0043] Combined with reference Figure 2 and Figure 3In one embodiment, the unlocking member 300 is rotatably connected to the first fastener 100 via a rotating shaft 301. The number of rotating shafts 301 is correspondingly two and they are located on opposite sides of the first fastener 100. The axial direction of the rotating shaft 301 is perpendicular to the connection direction. Specifically, the unlocking member 300 includes a connected limiting end 310 and an operating end 320. The limiting end 310 is located in the installation cavity 110 and can be relatively limited by the engaging portion 210; the operating end 320 extends out of the installation cavity 110 for user operation. Limiting protrusions 211 are provided on opposite sides of the engaging portion 210. When the engaging portion 210 is engaged in the installation cavity 110, the two limiting protrusions 211 and the two limiting ends 310 are hooked to each other, so that the unlocking member 300 and the engaging portion 210 are mutually limited. The user can press the unlocking member 300, causing it to rotate about the rotation axis 301 relative to the first fastener 100, driving the limiting end 310 to shift and separate from the limiting protrusion 211, thereby releasing the relative position between the unlocking member 300 and the engaging portion 210. At this point, the engaging portion 210 can be disengaged from the mounting cavity 110, and the second fastener 200 can be moved away from the first fastener 100, disconnecting the watchband connection structure 10.

[0044] It should be understood that, first, the rotational connection is only a specific way for the unlocking member 300 to be movably connected to the first fastener 100. In other embodiments, the unlocking member 300 can also be slidably connected to the first fastener 100. Therefore, in the present application, the implementation method of the unlocking member 300 being movably connected to the first fastener 100 is not limited; secondly, the mutual hooking of the limiting protrusion 211 and the limiting end 310 is only a specific way to achieve relative limitation between the unlocking member 300 and the locking portion 210. In other embodiments, relative limitation can also be achieved by methods such as the locking block and the locking slot, direct abutment, etc. Therefore, in the present application, the implementation method of the relative limitation between the unlocking member 300 and the locking portion 210 is not limited.

[0045] Specifically, refer to Figure 2In this embodiment, the unlocking member 300 has a guide slope 330 on the side facing the engaging portion 210. The length of the guide slope 330 extends in an angled direction relative to the connection direction between the first fastener 100 and the second fastener 200. As the engaging portion 210 enters the mounting cavity 110, the end of the limiting protrusion 211 moves along the guide slope 330 and always abuts against it, driving the unlocking member 300 to rotate while the elastic member 400 accumulates elastic force. When the limiting protrusion 211 passes over the guide slope 330, the elastic member 400 releases its elastic force, causing the limiting end 310 to instantly rebound and reposition, hooking onto the limiting protrusion 211. The unlocking member 300 is then restrained relative to the engaging portion 210. To unlock, the user presses the two unlocking members 300 to rotate in opposite directions. As shown in the figure, the two limiting protrusions 211 are located between the two guiding slopes 330, and the distance between the two limiting protrusions 211 is fixed, so the two guiding slopes 330 are always abutted by the ends of the limiting protrusions 211, and the unlocking member 300 rotates to keep the distance between the contact points of the two guiding slopes 330 and the ends of the limiting protrusions 211 unchanged.

[0046] It should be understood that the guide slope 330 is intended to guide the engagement portion 210 and the unlocking member 300 in relative position, reducing movement resistance and contact friction and wear during the movement of the engagement portion 210. In other embodiments, a circular arc surface can also be used to achieve the same technical effect. Therefore, the specific implementation of the guide slope 330 is not limited in this application.

[0047] In addition, combined with reference Figure 2 and Figure 3 In this embodiment, the elastic member 400 includes a telescopic spring 410, and the telescopic direction of the telescopic spring 410 is inclined to the connection direction, so as to facilitate the rotation of the unlocking member 300 and accumulate elastic force. Figure 3 As shown, the opposite ends of the telescopic spring 410 are respectively fixed to the inner wall of the installation cavity 110 and the limit end 310. The limit end 310 is also provided with a connecting rod 311. The telescopic spring 410 is sleeved on the outer side of the connecting rod 311 to install and fix the telescopic spring 410 to prevent the telescopic spring 410 from being twisted and deformed along its radial direction and damaged.

[0048] It should be understood that, first, in other embodiments, a torsion spring can also achieve the technical effect of accumulating and releasing elastic force during the rotational connection process. Therefore, in this application, the implementation method of the elastic member 400 is not limited. Secondly, the connection rod 311 provided on the inner sidewall of the mounting cavity 110 can also achieve the technical effect of fixing the telescopic spring. Therefore, in this application, the location of the connection rod 311 is not limited. In addition, without considering the twisting and deformation of the telescopic spring 410, in this application, whether the connection rod 311 is provided is not limited.

[0049] Combined with reference Figures 2-4The strap connection structure 10 also includes a magnetic attraction component 500, which includes a first magnet 510 and a second magnet 520 that are attracted to each other and arranged in alignment. The first magnet 510 is provided on the first fastener 100, and the second magnet 520 is provided on the second fastener 200. The first fastener 100 and the second fastener 200 are further magnetically fixed by the magnetic attraction component 500 to improve the connection stability. Specifically, the first fastener 100 is provided with a first placement groove 111 on the inner side wall of the mounting cavity 110, and the first placement groove 111 is used to accommodate the first magnet 510; the outer surface of the locking portion 210 is provided with a second placement groove 212, and the second placement groove 212 is used to accommodate the second magnet 520. The first magnet 510 and the second magnet 520 are magnetically aligned, and the openings of the first placement groove 111 and the second placement groove 212 are opposite. The magnetic assembly 500 further includes a cushion 530 disposed between the first magnet 510 and the second magnet 520. The cushion 530 covers the first placement slot 111 or the second placement slot 212. It should be understood that, in this application, the number of first magnets 510 and second magnets 520 is the same, but the number is not limited; the number of first placement slots 111 and second placement slots 212 is the same and their openings face each other, and the number is not limited.

[0050] The present invention provides a watchband connection structure 10 and a wearable device. The watchband connection structure 10 is used to connect a first watchband and a second watchband to form a wearable device worn on a user's wrist. On the one hand, the first fastener 100 and the second fastener 200 in the watchband connection structure 10 are dually fixedly connected through a limited snap connection (unlocking member 300 and locking portion 210) and magnetic attraction (magnetic attraction component 500). Compared with traditional connection structures, the connection stability is stronger, so the watchband connection structure 10 will not be easily disconnected due to the shaking of the user's arm. On the other hand, the unlocking member 300 is movably connected to opposite sides of the first fastener 100. This structure conforms to the ergonomic design and is convenient for the user to press. The user only needs to pinch two fingers to easily unlock and open the watchband connection structure 10. This is more convenient than unlocking the traditional watchband connection structure 10. Therefore, the watchband connection structure 10 of the present application has a simple structure, is more convenient to assemble and disassemble, and is suitable for more types of watchbands to meet the user's diverse needs for watchband matching.

[0051] Second embodiment

[0052] Combined with reference Figure 5 and Figure 6The watchband connection structure 10 of this embodiment has basically the same basic components and connection methods as the watchband connection structure 10 in the first embodiment. The first fastener 100 and the second fastener 200 are also doubly fixedly connected by limiting snap connection (unlocking member 300 and locking portion 210) and magnetic adsorption (magnetic component 500). The setting of the magnetic component 500 is the same as that of the first embodiment. The sleeve design between the telescopic spring 410 and the connecting rod 311 is the same as that of the first embodiment. The difference lies in the connection details between the unlocking member 300 and the locking portion 210.

[0053] Specifically, refer to Figure 7 In this embodiment, the unlocking member 300 is slidably connected to the first fastener 100. A sliding groove 340 is defined on the unlocking member 300. A protruding post 120 is provided on one side of the first fastener 100 facing the sliding groove 340. The protruding post 120 engages with the sliding groove 340. Pressing the unlocking member 300 causes the protruding post 120 to slide synchronously within the sliding groove 340. Each unlocking member 300 includes a limiting end 310 and an operating end 320. The limiting end 310 is located within the mounting cavity 110, while the operating end 320 extends outside the mounting cavity 110 for user operation. Protruding limiting protrusions 211 are provided on opposite sides of the engaging portion 210. When the engaging portion 210 is engaged with the mounting cavity 110, the limiting protrusions 211 engage with the limiting end 310, thereby limiting the unlocking member 300 and the engaging portion 210. To unlock the watch, a clearance notch 350 is provided between the limiting end 310 and the operating end 320. The unlocking member 300 can move relative to the first fastener 100, causing the limiting end 310 to misalign with the limiting protrusion 211. After the limiting protrusion 211 aligns with the clearance notch 350, the limiting protrusion 211 can move within the clearance notch 350, thereby releasing the relative position between the unlocking member 300 and the engaging portion 210. At this point, the engaging portion 210 can be disengaged from the mounting cavity 110, the second fastener 200 can be moved away from the first fastener 100, and the watchband connection structure 10 is disconnected. It should be noted that in this embodiment, the slide groove 340 and the boss 120 cooperate with each other to enable the unlocking member 300 to be movably connected to the first fastener 100, and the positions of the two can be interchanged. It is sufficient that one of the unlocking member 300 and the first fastener 100 is provided with the slide groove 340 and the other is provided with the boss 120.

[0054] Combined with reference Figure 6 and Figure 7In this embodiment, the inner sidewall of the clearance notch 350 is provided with a guiding slope 330, the length of which extends in a direction inclined relative to the connection direction between the first fastener 100 and the second fastener 200. As the engaging portion 210 moves into the mounting cavity 110, the limiting protrusion 211 moves along the guiding slope 330 within the clearance notch 350, driving the unlocking member 300 to move, and the elastic member 400 accumulates elastic force. When the limiting protrusion 211 moves out of the clearance notch 350, the elastic force released by the elastic member 400 causes the limiting end 310 to instantly rebound and hook onto the limiting protrusion 211, thereby limiting the unlocking member 300 relative to the engaging portion 210. To unlock, the user presses the two unlocking members 300 to drive the two limiting ends 310 to move until they are offset and separated from the two limiting protrusions 211. The limiting protrusion 211 then enters the clearance notch 350 and moves freely.

[0055] refer to Figure 7 In this embodiment, since the unlocking member 300 is slidably connected to the first fastener 100, to save effort, the length of the slide groove 340 is perpendicular to the connection direction between the first fastener 100 and the second fastener 200. The elastic member 400 includes a telescopic spring 410, the telescopic spring 410's expansion and contraction direction being parallel to the length of the slide groove 340. The opposite ends of the telescopic spring 410 are respectively fixed to the inner sidewall of the mounting cavity 110 and the unlocking member 300. The unlocking member 300 also includes a connecting rod 311, which is sleeved on the outer side of the connecting rod 311 to secure the telescopic spring 410 and prevent the telescopic spring 410 from twisting and deforming in its radial direction and causing damage. It should be understood that in other embodiments, the length of the slide groove 340 does not necessarily need to be perpendicular to the connection direction between the first fastener 100 and the second fastener 200; it is sufficient that the expansion and contraction direction of the telescopic spring 410 is parallel to the length of the slide groove 340.

[0056] While the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims. Therefore, all changes and modifications that fall within the scope of the claims or their equivalents are intended to be covered by the appended claims.
