[Specific implementation method] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0018] See also Figures 1 to 7 , a split-type watch strap connection mechanism, comprising a button assembly 2 arranged on a watch strap body 1, the button assembly 2 comprising 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 with the telescopic channel 211 and for the button 23 to move up and down, the two sides of the watch strap body 1 are respectively provided with ear holes 11 connected with the corresponding telescopic channels 211, the spring ears 22 are respectively arranged in the telescopic channels 211 with intervals and relative sliding, and the heads of the spring ears 22 are respectively extended or retracted from the ear holes 11, the elastic member 24 is arranged between the spring ears 22, and the elastic member 24 is against the spring ears 22 in the initial state so that the spring ears 22 extend out of the ear holes 11, the buttons 23 are respectively matched 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.

[0019] In this embodiment, a telescopic channel for the sliding of the ear and a lifting channel for the button to slide up and down are provided in the mounting shell, and an elastic member is provided to keep the ear in an extended state in the initial state, while the button cooperates with the ear and the ear can be retracted into the ear hole by pressing the button. This design does not require the use of a special disassembly jig, and consumers can easily disassemble and replace the watch strap by themselves, which improves the maintainability of the wearable device and provides a more simple and elegant use experience; The elastic member 24 is initially pressed against the ear 22 to make the ear 22 extend out of the ear hole 11, thereby connecting with the inner side of the dial to complete the installation; 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.

[0020] Furthermore, as a preferred implementation of the present solution but not a limitation, the tail of the 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 .

[0021] In this embodiment, the side of the button close to the abutment is a trapezoidal surface, which plays a guiding role. When the button is pressed and moved toward the ear, the inclined surface of the trapezoidal surface squeezes the abutment closer to each other and drives the ear to retract into the ear hole. This process is easy and easy to operate. The abutment is set in a ball head shape or other shapes, which can further increase its contact area and force uniformity with the trapezoidal surface, and enhance 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 adapt to the connection requirements of watchbands of different sizes or types, or setting other forms of driving structures on the button, such as cams or sliders, to achieve similar convenient disassembly functions.

[0022] Furthermore, as a preferred implementation mode of the present invention but not a limitation, when the ear 22 extends out of the ear hole 11, the abutment member 221 abuts against the bottom of the inclined surface of the trapezoidal surface 231; when the ear 22 is retracted into the ear hole 11, the abutment member 221 abuts against the top of the inclined surface of the trapezoidal surface 231.

[0023] In this embodiment, it is possible to maintain stable contact with the button 23, thereby ensuring the reliability of the operation. Secondly, through the inclined surface design of the trapezoidal surface 231, the ear 22 can be precisely controlled, so that the ear 22 can maintain a stable position when extending and retracting, reducing misoperation or damage caused by improper operation. In addition, including but not limited to changing the trapezoidal surface 231 to a guide surface of other shapes, such as an arc surface or a polygonal inclined surface, to achieve similar functions of maintaining and switching the extended and retracted states.

[0024] 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 from the opening 2131.

[0025] In this embodiment, the mounting housing 21 is divided into an upper cover 213 and a base 214, and a detachable connection is adopted to facilitate assembly and replacement of internal parts. The upper cover 213 and the base 214 together constitute a telescopic channel 211 and a lifting channel 212, which provide precise guidance and positioning for the movement of the ear 22 and the button 23. The setting of the opening 2131 enables the upper end of the button 23 to protrude from the upper cover 213, which is convenient for user operation. And including but not limited to, the upper cover 213 and the base 214 are connected by snaps, threads or other forms of detachable connection to achieve quick disassembly and replacement.

[0026] Further, as a preferred implementation manner of the present 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 .

[0027] In this embodiment, the depth of the lifting channel 212 is greater than the depth of the telescopic channel 211, which can provide 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 pressing process, thereby effectively pushing the spring ear 22 into the ear hole 11, and realizing convenient removal of the watchband. At the same time, this design can also enhance the stability and reliability of the mechanism, and avoid failure or jamming caused by insufficient travel of the button 23.

[0028] Furthermore, as a preferred implementation manner 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.

[0029] In this embodiment, by providing a limiting groove 222 at the rear end of the spring ear 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 kept between the spring ears 22 on both sides, providing stable elastic support for the movement of the spring ears 22, and also ensures that when the key is pressed, the spring ears on both sides retract inwardly at the same time, avoiding the situation that one side of the spring ear is fully retracted while the other side of the spring ear is not fully retracted, which may cause the strap and the case to be detached unsmoothly, or the spring ear is bent.

[0030] Further, as a preferred implementation of the present solution but not a limitation, the abutment member 221 is configured to be in the shape of a ball head.

[0031] 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 operation of the mechanism and reduce the risk of wear and jamming.

[0032] Further, as a preferred implementation mode of the present scheme 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 so that the ear 22 is retracted into the ear hole 11, and 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 the abutment 221 pushes the inclined surface of the trapezoidal surface 231 so that the button 23 is reset upward along the lifting channel 212.

[0033] Furthermore, as a preferred embodiment of the present invention but not a limitation, the upper cover 213 is provided with a positioning hole 2132, 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.

[0034] 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 accurately positioned and firmly fixed. The coordinated use of the positioning holes 2132 and the connecting holes 2141 can not only ensure that the relative positions of the upper cover 213 and the base 214 are accurate during the assembly process, but also provide sufficient connection strength to ensure the stability and reliability of the mechanism during use.

[0035] Further, as a preferred implementation of the present solution but not a limitation, the length of the lifting channel 212 is smaller than the length of the telescopic channel 211 .

[0036] 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 misalignment caused by excessive travel.

[0037] Furthermore, as a preferred implementation manner of the present solution but not a limitation, the spring ear 22 and the abutment member 221 are integrally formed or the spring ear 22 and the abutment member 221 are separate and connected by laser welding.

[0038] In this embodiment, the laser welding method is as follows Figure 5 As shown in FIG. 1 , the bottom of the abutment member extends to the limit groove in the ear for laser welding, and the bottom of the abutment member is a plane; the second laser welding method is as shown in FIG. Figure 7 The bottom of the abutment piece is shown as extending one side to the limit groove in the spring ear, and the other side to the center axis of the spring ear for laser welding.

[0039] Further, as a preferred implementation of the present solution but not a limitation, the said ear 22 is provided with an annular protrusion 223 arranged along the circumferential outer surface of the said ear 22. In the present embodiment 3, the preferred number of the annular protrusions is set to two, including but not limited to other numbers of annular protrusions. The setting of the annular protrusions can reduce the contact area between the ear and the telescopic channel, reduce the friction force, and make the extension and contraction of the ear smoother. On the other hand, it also ensures that the ear will not be loose in the telescopic channel and produce abnormal noise.

[0040] The working principle of this embodiment is as follows: The present invention discloses a split watchband connection mechanism, which provides a telescopic channel for the ear to slide and a lifting channel for the button to slide up and down in the mounting shell, and provides an elastic member to keep the ear in an extended state in the initial state, while the button cooperates with the ear and can retract the ear into the ear hole by pressing the button. This design does not require the use of a special disassembly jig, and consumers can easily disassemble and replace the watchband by themselves, which improves the maintainability of the wearable device and provides a more simple and elegant use experience.

[0041] The above are implementation methods provided in combination with specific contents, and it is not intended that the specific implementation of this application is limited to these descriptions. Any method structure similar to the present application, or a number of technical deductions or replacements based on the concept of the present application, should be considered as the protection scope of this application.
