[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 9 An integrated watch band connection mechanism includes a watch ear 1 and a button assembly 2 arranged on the watch ear 1. The watch ear 1 is provided with an installation groove 11 for installing the button assembly 2. The button assembly 2 includes a raw ear 21, a button 22, and an elastic member 23. The installation groove 11 is provided with a telescopic channel 111 that runs through the left and right sides of the watch ear 1 and a lifting channel 112 that is connected to the telescopic channel 111 and allows the button 22 to move up and down. The two sides of the watch ear 1 are respectively provided with a corresponding telescopic channel 11. 1, the ears 21 are arranged in the telescopic channel 111 to slide relative to each other at intervals, and the heads of the ears 21 are respectively extended from or retracted from the ear holes 12, the elastic members 23 are arranged between the ears 21, and the elastic members 23 abut against the ears 21 in an initial state so that the ears 21 extend out of the ear holes 12, and the buttons 22 are respectively matched with the ears 21 so that when the buttons 22 are pressed down along the lifting channel 112, the ears 21 are retracted into the ear holes 12.

[0019] The present application discloses an integrated watch strap connection mechanism, which directly opens a mounting groove on the watch ear and sets a telescopic channel for the lug to slide and a lifting channel for the button to slide up and down in the mounting groove, and sets an elastic member to keep the lug in an extended state in the initial state, while the button cooperates with the lug, and the lug 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 wearable devices and provides a more simple and elegant user experience; The elastic member presses against the spring ear in the initial state so that the spring ear extends out of the ear hole, thereby connecting with the inner side of the dial to complete the installation; The buttons cooperate with the spring ears respectively, so that when the buttons are pressed down along the lifting channel, the spring ears are retracted into the ear holes 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 use of external tools.

[0020] Furthermore, as a preferred implementation of the present solution but not a limitation, an oblique push surface 221 is provided on the bottom side of the button 22 , and an abutment member 211 abutting against the oblique push surface 221 is provided at the tail of the spring ear 21 .

[0021] In this embodiment, the side of the button close to the abutment is an inclined push surface, which plays a guiding role. When the button is pressed and moved towards the raw ear, the inclined push surfaces press the abutment towards each other and drive the raw 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 21 extends out of the ear hole 12, the abutment member 211 abuts against the bottom of the inclined push surface 221; when the ear 21 retracts into the ear hole 12, the abutment member 211 abuts against the top of the inclined push surface 221.

[0023] In this embodiment, the button can be kept in stable contact, thereby ensuring the reliability of the operation. Secondly, the inclined surface design of the inclined push surface can achieve precise control of the spring ear, so that the spring ear 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 inclined push surface 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 implementation of the present solution but not a limitation, a limiting protrusion 222 is provided on the button 22 at the bottom corresponding to the inclined push surface 221 for the abutment member 211 to abut against to limit the button 22 from falling out of the installation slot 11 .

[0025] In this embodiment, by providing a limiting protrusion 222 on the button 22 and cooperating with the abutment 211 of the ear 21, the elastic member can always push the abutment outward when the button is not subjected to external force, so that under the action of the inclined push surface, the limiting protrusion remains in abutment with the abutment, thereby effectively limiting the movement range of the button 22 in the installation groove 11, preventing it from falling out of the installation groove 11, increasing the stability and reliability of the button 22 during use, and avoiding failure of the watchband connection mechanism due to accidental fall-out of the button 22.

[0026] Furthermore, as a preferred implementation of the present solution but not a limitation, the upper end of the button 22 protrudes outward from the mounting groove 11 .

[0027] In this embodiment, by designing the upper end of the button 22 to protrude from the mounting groove 11, it is convenient for the user to press the button during use, thereby improving the convenience and comfort of operation. At the same time, the protruding design can also increase the visibility and recognizability of the button 22, so that the user can find and use the button 22 more easily.

[0028] Further, as a preferred implementation manner of the present solution but not a limitation, the depth of the lifting channel 112 sunk into the installation groove 11 is greater than the depth of the telescopic channel 111 located in the installation groove 11 .

[0029] In this embodiment, the depth of the lifting channel is greater than the depth of the telescopic channel, which can provide sufficient travel space for the button, ensuring that it can fully interact with the abutment of the spring ear during the pressing process, thereby effectively pushing the spring ear into the ear hole, and realizing convenient removal of the watchband. At the same time, this design can also enhance the stability and reliability of the mechanism, avoiding failure or jamming caused by insufficient button travel.

[0030] Furthermore, as a preferred implementation manner of the present invention but not a limitation, a limiting groove 212 is provided at the tail end of the raw ear 21, and both ends of the elastic member 23 are respectively embedded in the limiting groove 212 of the raw ear 21, so that the elastic member 23 is maintained between the raw ears 21 on both sides.

[0031] In this embodiment, by providing a limit groove at the rear end of the spring ear and embedding the two ends of the elastic member therein, the elastic member is effectively fixed and positioned. This ensures that the elastic member is always kept between the two spring ears, providing stable elastic support for the movement of the spring ears, and also ensures that when the key is pressed, the inward retraction stroke of the two spring ears is synchronized, avoiding the situation that the strap and the watch case are not smoothly removed, or the spring ears are bent, when one spring ear is fully retracted while the other is not fully retracted.

[0032] Further, as a preferred implementation of the present solution but not a limitation, the abutment member 211 is configured to be in the shape of a ball head.

[0033] 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.

[0034] Further, as a preferred implementation mode of the present scheme but not a limitation, when the button 22 is pressed down along the lifting channel 112 by an external force, the inclined surface of the inclined push surface 221 contacts the abutment 211 to retract the ear 21 into the ear hole 12, and at the same time the elastic member 23 is compressed; when the button 22 is not subjected to an external force, the ear 21 extends out of the ear hole 12 under the elastic force of the elastic member 23, and at the same time the abutment 211 pushes the inclined push surface 221 to reset the button 22 upward along the lifting channel 112, and then the limiting protrusion 222 contacts the abutment 211 to limit the button 22 from falling out of the mounting groove 11.

[0035] Further, as a preferred implementation of the present solution but not a limitation, the spacing distance between the limiting protrusion 222 and the bottom of the inclined push surface 221 is S, and the diameter of the abutment member 211 is L, wherein S≥L.

[0036] In this embodiment, it can be ensured that when the button 22 is pressed down, the abutment member 211 can smoothly slide along the inclined push surface 221 to the bottom of the inclined push surface, making full use of the sliding stroke of the inclined push surface to retract the ear 21 into the ear hole 12.

[0037] Furthermore, as a preferred implementation manner of the present solution but not a limitation, the spring ear 21 and the abutment member 211 are integrally formed or the spring ear 21 and the abutment member 211 are separate and connected by laser welding.

[0038] In this embodiment, laser welding method 1, such as Figure 7 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; laser welding method 2, such as Fig. 9The 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 21 is provided with an annular protrusion 213 arranged along the circumferential outer surface of the said ear 21. 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 application discloses an integrated watch strap connection mechanism, which directly opens a mounting groove on the watch ear and sets a telescopic channel for the lug to slide and a lifting channel for the button to slide up and down in the mounting groove, and sets an elastic member to keep the lug in an extended state in the initial state, while the button cooperates with the lug, and the lug 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 wearable devices 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.
