[0028] Example

[0029] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of this application. Figure 2This is a first-person perspective exploded structural diagram of the present application. This embodiment provides a quick-release mechanism for a watch strap 31, including a housing assembly 1, an unlocking assembly 2, and a watch strap assembly 3. The unlocking assembly 2 is disposed on the housing assembly 1 and is detachably fixedly connected to the watch strap assembly 3. The housing assembly 1 includes an upper cover 11, a middle frame 12, and a bottom cover 13. The upper cover 11 is provided with a mounting hole 111, which is a through hole penetrating the upper and lower surfaces of the upper cover 11 to accommodate the unlocking button 21 in the unlocking assembly 2, providing guidance and installation space for the up and down sliding of the unlocking button 21. The horizontal cross-section of the mounting hole 111 can be circular or elongated. In another embodiment of this application, an annular boss can be added circumferentially to the mounting hole 111. The inner wall of the annular boss is provided with a spiral guide groove 121. The spiral angle of the spiral guide groove 121 is 13~17°. The outer wall of the unlock button 21 is provided with a corresponding guide ridge. The annular boss and the guide ridge cooperate to form a spiral lifting structure, realizing the rotational guidance function when pressing to unlock, preventing the unlock button 21 from getting stuck. In addition, this spiral lifting structure allows the unlock button 21 to rotate slightly during the pressing process, which helps to better control the movement trajectory of the button and bring clearer operation feedback.

[0030] The middle frame 12 is located below the upper cover 11 and is detachably fixed to the upper cover 11 by a number of evenly distributed buckles or screws. The middle frame 12 has a laterally extending guide groove 121, and a first magnet 122 is provided on the side wall of the guide groove 121. Specifically, the first magnet 122 can be embedded into the side wall of the guide groove 121 and fixed by glue or screws. The bottom cover 13 is located below the middle frame 12 and is fixed to the middle frame 12 by adhesive. The bottom cover 13 can further fix the middle frame 12 and prevent the middle frame 12 from shaking due to external forces during use, which would cause the first magnet 122 and other components to fall off from the installation position. The upper cover 11, middle frame 12 and bottom cover 13 are all made of aluminum alloy, copper or ceramic to improve the heat dissipation performance of the mechanism.

[0031] Please see Figure 3 and Figure 4 , Figure 3 This is a second-view exploded structure diagram of this application. Figure 4This is a schematic diagram of the assembly of the unlocking component and the watch strap component of this application. The unlocking component 2 includes an unlocking button 21, a left slider 22, a right slider 23, and a return spring 24. The shape of the unlocking button 21 matches the shape of the mounting hole 111. The unlocking button 21 can be slidably installed in the mounting hole 111. Two symmetrically arranged inclined push blocks 211 are provided at its bottom, and the inclined push blocks 211 are connected to the guide groove 121 by an elastic connector 212. Alternatively, a guide post can be provided at the bottom of the guide groove 121, and the elastic connector 212 can be sleeved on the guide post. This ensures that when the unlocking button 21 is pressed, the inclined push block 211 is pressed down along the axis of the guide post, improving the guiding accuracy of the inclined push block 211 during the movement. The left slider 22 and right slider 23 are respectively disposed in the guide groove 121 and abut against the corresponding inclined push block 211 to form an inclined drive engagement. In this embodiment, the left slider 22 and right slider 23 form a 45~60° self-locking angle with the corresponding inclined push block 211 to ensure that the left slider 22 and right slider 23 move synchronously when unlocking. The left slider 22 and right slider 23 are connected by a return spring 24, so that after the unlock button 21 is released, the left and right sliders 23 can automatically return to their initial positions under the action of the return spring 24. The left slider 22 and right slider 23 move away from the return spring 24. Each end of the spring 24 is provided with a first locking protrusion 221 and a second locking protrusion 231. More specifically, the end of the left slider 22 away from the return spring 24 is provided with an integrally formed first locking protrusion 221, and the end of the right slider 23 away from the return spring 24 is provided with an integrally formed second locking protrusion 231. The first locking protrusion 221 and the second locking protrusion 231 are both stepped to accommodate different sizes of limiting grooves and to fit different specifications of watch strap 31 end links, making the quick release mechanism of watch strap 31 more compatible and meeting the diverse watch strap 31 replacement needs of users.

[0032] See also Figure 2 and Figure 3 The watch strap assembly 3 includes a watch strap 31 and a watch strap 31 end link. The watch strap 31 has a mounting groove, and the watch strap 31 end link is located in the mounting groove. The watch strap 31 end link is detachably fixed to the watch strap 31 by means of screws or buckles, so as to replace different styles of watch strap 31 end links or watch strap 31. A second magnet 321 is embedded in the watch strap 31 end link. The second magnet 321 and the first magnet 122 are magnetically attracted to each other to assist in the positioning of the watch strap 31 end link. The two ends of the watch strap 31 end link are provided with a first limiting groove 322 and a second limiting groove 323 that cooperate with the first locking protrusion 221 and the second locking protrusion 231. More specifically, the first locking protrusion 221 cooperates with the first limiting groove 322, and the second locking protrusion 231 cooperates with the second limiting groove 323.

[0033] In use, when the end link of the watch strap 31 is inserted into place, the first locking protrusion 221 inserts into the first limiting groove 322, and the second locking protrusion 231 inserts into the second limiting groove 323, thereby achieving quick locking of the watch strap 31. At the same time, the first magnet 122 and the second magnet 321 attract each other, providing auxiliary holding force. If the watch strap 31 and the end link of the watch strap 31 need to be replaced, simply press the unlock button 21. The inclined push block 211 at its bottom pushes the left slider 22 and the right slider 23 to slide towards the center along the guide groove 121 against the elastic force of the return spring 24, so that the locking protrusion disengages from the locking groove and releases the mechanical lock. At this time, under the action of magnetic attraction or slight external force, the end link of the watch strap 31 along with the watch strap 31 can be removed. After releasing the unlock button 21, under the action of the return spring 24, the left slider 22 and the right slider 23 automatically return to the initial position, waiting for the next connection.

[0034] The technical solution of this application has the following advantages: First, it is convenient and efficient to operate. Whether installing or removing the watch strap 31, it can be completed quickly with one hand without tools, making the operation extremely convenient and efficient. Furthermore, the locking protrusions at the ends of the left and right sliders 23 and the limiting grooves on both sides of the end links of the watch strap 31 are tightly engaged to form a firm mechanical lock. Combined with the strong auxiliary magnetic attraction of the first magnet 122 and the second magnet 321, it can not only significantly enhance the positioning accuracy and fit stability of the end links of the watch strap 31 during installation, but also provide additional holding force after locking, effectively preventing accidental disengagement and ensuring wearing safety. After releasing the unlock button 21, the reset spring 24 connecting the left and right sliders 23 will automatically push the left and right sliders 23 back to their initial positions, eliminating the hassle of manual reset and improving the smoothness and reliability of operation. Second, the positioning is accurate and reliable. The first magnet 122 of the middle frame 12 and the second magnet 321 of the end piece of the strap 31 magnetically cooperate to help the end piece of the strap 31 quickly align with the installation position, reducing manual adjustment errors. Combined with the locking protrusion and the limiting groove, a mechanical locking structure is formed, which doubles the guarantee of the stability of the strap 31 connection and prevents it from loosening and falling off during use. Third, the structure is compact and durable. The top cover 11 and the middle frame 12 are detachably connected, which facilitates the assembly, maintenance or replacement of the internal unlocking component 2. The strap 31 and the end piece of the strap 31 are detachably fixedly connected, which makes it convenient to replace the worn strap 31 or upgrade the end piece of different materials, extending the product life. The guide groove 121 provides a stable movement trajectory for the slider and prevents deviation and jamming. The left and right sliders 23 are symmetrically arranged and the force is evenly distributed. With the help of the reset spring 24, they can automatically return to their original position, which improves the durability of the mechanism. In summary, the combination of one-button unlocking, magnetic assisted positioning, and spring automatic reset design solves the pain point of cumbersome replacement of traditional watch straps. It achieves true one-handed instant disassembly and assembly, making operation extremely convenient. At the same time, the dual protection of mechanical locking and magnetic positioning provides reliability and security far exceeding that of pure magnetic structures. It has the advantages of simple structure, compact size, small size, and safety and reliability, making it difficult to loosen.
