To facilitate the removal and replacement of the strap, existing head beads are equipped with spring tabs to connect the strap and dial. To remove the strap, a special removal jig is required to push out the spring tabs. However, such removal jigs are often only available in repair shops, and consumers generally do not carry them with them, making maintenance difficult. [Utility Model Content]
[0006] In order to solve the problem of inconvenient disassembly of the watch strap and the dial in the prior art, the present application provides a split watch strap connection mechanism.
[0007] This application is achieved through the following technical solutions:

The mounting shell is provided with a telescopic channel running through left and right sides, and a lifting channel connected to the telescopic channel and for the button to move up and down. Ear holes connected to the corresponding telescopic channels are respectively provided on both sides of the watchband body. The spring ears are respectively arranged in the telescopic channels for relative sliding at intervals, and the heads of the spring ears are respectively extended or retracted from the ear holes. The elastic member is provided between the spring ears and, in an initial state, presses against the spring ears so that the spring ears extend out of the ear holes. The buttons cooperate with the spring ears so that when the buttons are pressed down along the lifting channel, the spring ears are retracted into the ear holes.
[0009] In the split watchband connection mechanism as described above, the tail of the spring ear is provided with an abutment member extending to below the button, and the button has a trapezoidal surface on the side close to the abutment member.
[0010] In the split watchband connection mechanism as described above, when the ear extends out of the ear hole, the abutment member abuts against the bottom of the inclined surface of the trapezoidal surface; when the ear is retracted into the ear hole, the abutment member abuts against the top of the inclined surface of the trapezoidal surface.

[0030] In order to make the technical problems, technical solutions and beneficial effects solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.
[0031] See also Figures 1 to 7 , a split watchband connecting mechanism includes a button assembly 2 provided on a watchband body 1, the button assembly 2 including a mounting shell 21, a spring ear 22, a button 23, and an elastic member 24. The mounting shell 21 is provided with a telescopic channel 211 running through the left and right sides, and a lifting channel 212 connected to the telescopic channel 211 and allowing the button 23 to move up and down. Ear holes 11 connected to the corresponding telescopic channels 211 are respectively provided on both sides of the watchband body 1. The spring ears 22 are respectively slidably arranged in the telescopic channels 211 at intervals, and the heads of the spring ears 22 are respectively extended or retracted from the ear holes 11. The elastic member 24 is provided between the spring ears 22, and in the initial state, the elastic member 24 presses against the spring ears 22 so that the spring ears 22 extend out of the ear holes 11. The buttons 23 cooperate with the spring ears 22 so that when the buttons 23 are pressed down along the lifting channel 212, the spring ears 22 are retracted into the ear holes 11.
[0032] In this embodiment, a telescopic channel for the earpiece to slide and an elevating channel for the button to slide up and down are provided within the mounting housing. Elastic elements are provided to keep the earpiece extended in its initial state, while the button cooperates with the earpiece to retract into the ear canal by pressing the button. This design eliminates the need for specialized disassembly jigs, allowing consumers to easily remove and replace the watchband themselves, improving the wearable device's maintainability and providing a more streamlined and elegant user experience.
[0033] In the initial state, the elastic member 24 presses against the ear 22 to make the ear 22 extend out of the ear hole 11 and connect with the inner side of the dial, thus completing the installation;
[0034] The buttons 23 cooperate with the spring ears 22 respectively, so that when the buttons 23 are pressed down along the lifting channel 212, the spring ears 22 are retracted into the ear holes 11 to be released from the inner side of the dial to complete the removal. This installation and disassembly method is simple and fast, and does not require the help of external tools.
[0035] Furthermore, as a preferred embodiment of the present invention but not limitation, the tail of the spring ear 22 is provided with an abutment member 221 extending to below the button 23 , and the button 23 has a trapezoidal surface 231 on one side close to the abutment member 221 .
[0036] In this embodiment, the button has a trapezoidal surface on the side closest to the abutment, which serves as a guide. When the button is pressed and moved toward the ear, the inclined surface of the trapezoidal surface squeezes the abutment toward each other and drives the ear into the ear hole, making the process easy and simple to operate. The abutment is configured as a ball head or other shape to further increase its contact area with the trapezoidal surface and force uniformity, thereby enhancing the stability and durability of the mechanism. Other possible embodiments include, but are not limited to, changing the inclination angle or shape of the trapezoidal surface to accommodate the connection requirements of watchbands of different sizes or types, or providing other forms of drive structures on the button, such as cams or sliders, to achieve similar convenient disassembly functions.
[0037] Furthermore, as a preferred embodiment of the present invention but not a limitation, when the ear 22 extends out of the ear hole 11, the abutment 221 abuts against the bottom of the inclined surface of the trapezoidal surface 231; when the ear 22 retracts into the ear hole 11, the abutment 221 abuts against the top of the inclined surface of the trapezoidal surface 231.
[0038] In this embodiment, stable contact with the button 23 is maintained, ensuring operational reliability. Furthermore, the inclined design of the trapezoidal surface 231 allows for precise control of the spring tab 22, ensuring that the spring tab 22 maintains a stable position during both extension and retraction, reducing the risk of misoperation or damage due to improper operation. Furthermore, similar functions for maintaining and switching between extended and retracted states can be achieved, including but not limited to replacing the trapezoidal surface 231 with a guide surface of another shape, such as an arcuate surface or a polygonal inclined surface.
[0039] Furthermore, as a preferred embodiment of the present invention but not a limitation, the mounting shell 21 includes an upper cover 213 and a base 214, the upper cover 213 is detachably connected to the base 214 to form the telescopic channel 211 and the lifting channel 212, the upper cover 213 is provided with an opening 2131 connected to the lifting channel 212, and the upper end of the button 23 protrudes outward from the opening 2131.
[0040] In this embodiment, the mounting housing 21 is divided into an upper cover 213 and a base 214, and a detachable connection is employed to facilitate assembly and replacement of internal components. The upper cover 213 and base 214 together form a telescoping channel 211 and a lifting channel 212, providing precise guidance and positioning for the movement of the spring ears 22 and buttons 23. The provision of openings 2131 allows the upper ends of the buttons 23 to protrude beyond the upper cover 213, facilitating user operation. Furthermore, the upper cover 213 and base 214 can be connected using, but not limited to, snap-fit, threaded, or other detachable connections to facilitate quick assembly and disassembly and replacement.
[0041] Furthermore, as a preferred implementation manner of this solution but not a limitation, the depth of the lifting channel 212 sunk into the base 214 is greater than the depth of the telescopic channel 211 sunk into the base 214 .
[0042] In this embodiment, the depth of the lifting channel 212 is greater than the depth of the telescopic channel 211. This provides sufficient travel space for the button 23, ensuring that it can fully interact with the abutment member 221 of the spring ear 22 during the downward pressing process, thereby effectively pushing the spring ear 22 into the ear hole 11, allowing for convenient removal of the watchband. This design also enhances the stability and reliability of the mechanism, preventing failure or jamming caused by insufficient travel of the button 23.
[0043] Furthermore, as a preferred embodiment of the present invention but not a limitation, a limiting groove 222 is provided at the tail end of the raw ear 22, and both ends of the elastic member 24 are respectively embedded in the limiting groove 222 of the raw ear 22, so that the elastic member 24 is maintained between the raw ears 22 on both sides.
[0044] In this embodiment, by providing a retaining groove 222 at the rear end of the spring tab 22 and embedding the two ends of the elastic member 24 therein, the elastic member 24 is effectively fixed and positioned. This ensures that the elastic member 24 is always maintained between the two spring tabs 22, providing stable elastic support for the movement of the spring tabs 22. It also ensures that when the button is pressed, the inward retraction of the two spring tabs remains synchronized, preventing the situation where one spring tab is fully retracted while the other is not, which could lead to difficulty in removing the watchband from the watch case or the bending of the spring tabs.
[0045] Furthermore, as a preferred embodiment of this solution but not a limitation, the abutment member 221 is configured to be in the shape of a ball head.
[0046] In this embodiment, the ball-shaped abutment member can reduce stress concentration and friction resistance, which helps to improve the smoothness and stability of the mechanism's operation and reduce the risk of wear and seizure.
[0047] Furthermore, as a preferred embodiment of the present invention but not a limitation, when the button 23 is pressed down along the lifting channel 212 by an external force, the inclined surface of the trapezoidal surface 231 squeezes the abutment 221 to retract the ear 22 into the ear hole 11, and at the same time the elastic member 24 is compressed; when the button 23 is not subjected to an external force, the ear 22 extends out of the ear hole 11 under the elastic force of the elastic member 24, and at the same time the abutment 221 pushes the inclined surface of the trapezoidal surface 231 to reset the button 23 upward along the lifting channel 212.
[0048] Furthermore, as a preferred embodiment of the present invention but not a limitation, the upper cover 213 is provided with a positioning hole 2132, and the base 214 is provided with a connecting hole 2141, and a fastener passes through the positioning hole 2132 and the connecting hole 2141 in sequence to connect the upper cover 213 and the base 214.
[0049] In this embodiment, by providing positioning holes 2132 and connecting holes 2141 on the upper cover 213 and the base 214, and connecting them with fasteners, the upper cover 213 and the base 214 are precisely positioned and securely fixed. The coordinated use of positioning holes 2132 and connecting holes 2141 not only ensures the accurate relative positioning of the upper cover 213 and the base 214 during assembly, but also provides sufficient connection strength, ensuring the stability and reliability of the mechanism during use.
[0050] Furthermore, as a preferred embodiment of this solution but not a limitation, the length of the lifting channel 212 is smaller than the length of the telescopic channel 211 .
[0051] In this embodiment, both sides of the lifting channel in the length direction can abut against the abutment parts to limit the outward extension of the spring ear, ensure the stability and reliability of the spring ear 22 during the extension and retraction process, and avoid jamming or dislocation caused by excessive travel.
[0052] Furthermore, as a preferred embodiment of the present invention but not limitation, the spring ear 22 and the abutting member 221 are integrally formed or the spring ear 22 and the abutting member 221 are separate and connected by laser welding.
[0053] In this embodiment, the laser welding method is as follows Figure 5 As shown, the bottom of the abutment extends to the limit groove in the ear for laser welding, and the bottom of the abutment is a plane; the second laser welding method is as shown in FIG. Figure 7 As shown, one side of the bottom of the abutment extends to the limiting groove in the spring ear, and the other side extends to the central axis of the spring ear for laser welding.
[0054] Furthermore, as a preferred embodiment of this solution but not a limitation, the spring ear 22 is provided with an annular protrusion 223 disposed along the circumferential outer surface of the spring ear 22. In this third embodiment, the preferred number of annular protrusions is set to two, including but not limited to other numbers of annular protrusions. The provision of the annular protrusions can, on the one hand, reduce the contact area between the spring ear and the telescopic channel, lowering friction and making the extension and retraction of the spring ear smoother, and on the other hand, ensure that the spring ear does not become loose within the telescopic channel and produce abnormal noise.
[0055] The working principle of this embodiment is as follows:
[0056] This application describes a split-type watchband connection mechanism. This mechanism incorporates a telescopic channel within the mounting housing for the lug to slide, and an elevating channel for the button to slide up and down. Elastic elements are provided to maintain the lug in its initial extended position, while the button, in conjunction with the lug, allows the lug to retract into the ear canal by pressing the button. This design eliminates the need for specialized disassembly jigs, allowing consumers to easily remove and replace the watchband themselves. This improves the maintainability of the wearable device and provides a more streamlined and elegant user experience.
[0057] The above are implementation methods provided in conjunction with specific content, and the specific implementation of this application is not limited to these descriptions. Any method structure that is similar to the method structure of this application, or any technical deduction or replacement based on the concept of this application, should be considered as the scope of protection of this application.
