[0032] 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.

[0033] See also Figures 1 to 9An integrated watch strap connection mechanism includes a watch ear 1 and a button assembly 2 provided on the watch ear 1. The watch ear 1 is provided with a mounting groove 11 for mounting the button assembly 2. The button assembly 2 includes a spring ear 21, a button 22, and an elastic member 23. The mounting groove 11 is provided with a telescopic channel 111 that passes 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 raw ears 21 are respectively arranged in a relatively slidable manner in the telescopic channel 111 at intervals, and the heads of the raw ears 21 are respectively extended from or retracted from the ear holes 12. The elastic member 23 is provided between the raw ears 21, and in an initial state, the elastic member 23 presses against the raw ears 21 so that the raw ears 21 extend out of the ear holes 12. The buttons 22 respectively cooperate with the raw ears 21 so that when the buttons 22 are pressed down along the lifting channel 112, the raw ears 21 are retracted into the ear holes 12.

[0034] The present invention discloses an integrated watchband connection mechanism. This mechanism creates a mounting slot directly on the lug, within which a retractable channel for the lug to slide and a lift channel for the button to slide up and down are provided. Furthermore, an elastic member is provided to maintain the lug in its initial extended position. The button, in conjunction with the lug, retracts the lug 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.

[0035] In the initial state, the elastic member presses against the spring ear to make the spring ear extend out of the ear hole, thereby connecting with the inner side of the dial to complete the installation;

[0036] 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.

[0037] Furthermore, as a preferred embodiment of the present invention but not limitation, an oblique push surface 221 is provided on the bottom side of the button 22 , and an abutting piece 211 abutting against the oblique push surface 221 is provided at the tail of the spring ear 21 .

[0038] In this embodiment, the button has an inclined push surface on the side closest to the abutment, which acts as a guide. When the button is pressed and moved toward the ear, the inclined push surfaces press the abutment toward each other, driving the ear to retract into the ear hole. This process is easy and simple to operate. The abutment is configured as a ball head or other shape, which can 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.

[0039] Furthermore, as a preferred embodiment 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.

[0040] In this embodiment, stable contact with the key is maintained, ensuring operational reliability. Secondly, the inclined design of the push surface allows for precise control of the spring tab, ensuring it maintains a stable position both during extension and retraction, reducing the risk of misoperation or damage due to improper operation. Furthermore, other options, including but not limited to replacing the push surface with a guide surface of a different shape, such as an arcuate surface or a polygonal inclined surface, can achieve similar functions for maintaining and switching between extended and retracted states.

[0041] Furthermore, as a preferred embodiment of the present invention 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 .

[0042] 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, and then the limiting protrusion can maintain abutment with the abutment under the action of the inclined push surface, thereby effectively limiting the movement range of the button 22 in the installation slot 11, preventing it from falling out of the installation slot 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.

[0043] Furthermore, as a preferred implementation manner of this solution but not limitation, the upper end of the button 22 protrudes outward from the mounting groove 11 .

[0044] In this embodiment, by designing the upper end of the button 22 to protrude from the mounting slot 11, it is easier for the user to press the button during use, improving the convenience and comfort of operation. At the same time, the protruding design also increases the visibility and recognizability of the button 22, making it easier for the user to find and use the button 22.

[0045] Furthermore, as a preferred implementation manner of this 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 .

[0046] In this embodiment, the depth of the lifting channel is greater than the depth of the telescoping channel. This provides sufficient travel space for the button, ensuring that it can fully interact with the abutment of the spring tab during depression, effectively pushing the spring tab into the ear hole and facilitating easy removal of the watchband. This design also enhances the stability and reliability of the mechanism, preventing failure or jamming caused by insufficient button travel.

[0047] Furthermore, as a preferred embodiment 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.

[0048] In this embodiment, by providing a retaining groove at the rear end of the spring tab 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 maintained between the two spring tabs, providing stable elastic support for the movement of the spring tabs. 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, resulting in difficulty in removing the watchband from the watch case or bending of the spring tabs.

[0049] Furthermore, as a preferred embodiment of this solution but not a limitation, the abutting member 211 is configured to be in the shape of a ball head.

[0050] 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.

[0051] Furthermore, as a preferred embodiment of the present invention 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 slot 11.

[0052] Furthermore, as a preferred embodiment of the present invention but not 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 abutting member 211 is L, wherein S≥L.

[0053] In this embodiment, it can be ensured that when the button 22 is pressed, 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.

[0054] Furthermore, as a preferred embodiment of the present invention but not limitation, the spring ear 21 and the abutting member 211 are integrally formed or the spring ear 21 and the abutting member 211 are separate and connected by laser welding.

[0055] 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 Figure 9 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.

[0056] Furthermore, as a preferred embodiment of this solution but not a limitation, the spring ear 21 is provided with an annular protrusion 213 disposed along the circumferential outer surface of the spring ear 21. 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.

[0057] The working principle of this embodiment is as follows:

[0058] The present invention proposes an integrated watchband connection mechanism. This mechanism creates a mounting slot directly on the lug, within which a retractable channel for the lug to slide and a lift channel for the button to slide up and down are provided. Furthermore, an elastic member is provided to maintain the lug in its initial extended position. The button, in conjunction with the lug, retracts the lug 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.
