Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5The utility model provides a technical solution: a quick-release structure of a keyboard, comprising: a plurality of quick-release bead structures 2 evenly distributed around the edges of the keyboard, the keyboard comprising a bottom shell 3 and a surface cover 1 located above the bottom shell 3, a middle plate 4 is arranged between the bottom shell 3 and the surface cover 1, the middle plate 4 is fixed to the bottom shell 3 through the surface cover 1, each of the quick-release bead structures 2 comprises a fixing plate 21 fixed to the surface cover 1 and a clamping seat 23 fixed to the bottom shell 3, the clamping seat 23 is detachably connected to the fixing plate 21 through a detachable connecting mechanism; elastic beads 25 are installed on both sides of the clamping seat 23 for clamping and limiting the connecting mechanism, and the connecting mechanism is located between the two elastic beads 25.

[0028] During installation, the clip seat 23 is fixed on the bottom shell 3 of the keyboard, and then the fixing plate 21 is fixed on the surface cover 1 of the keyboard. When the clip seat 23 and the fixing plate 21 are connected through the connecting mechanism, the elastic clamping force between the two elastic bump beads 25 is used to clamp and fix the connection of the connecting mechanism, so that the surface cover 1 and the bottom shell 3 can be quickly installed. When disassembling, the surface cover 1 can be directly pulled away from the bottom shell 3 to separate the connecting mechanism. The operation is simple and there is no need to frequently tighten the screws, which improves the convenience of installing or disassembling the bottom shell 3 and the surface cover 1.

[0029] The connecting mechanism includes a limiting protrusion 22 fixed on one side of the fixing plate 21 and two supporting blocks 24 fixed on one side of the collision clamp seat 23. The two elastic collision beads 25 are respectively installed inside the supporting blocks 24, and when the limiting protrusion 22 is located between the two supporting blocks 24, one end of the elastic collision bead 25 passes through the supporting block 24 and contacts the side wall of the limiting protrusion 22. During installation, the limiting protrusion 22 is inserted between the two supporting blocks 24, and the elastic collision bead 25 is used to provide clamping force from the opposite sides of the limiting protrusion 22 to fix the limiting protrusion 22 between the two supporting blocks 24 and connect the clip to the collision clamp seat 23. During disassembly, it is only necessary to pull the limiting protrusion 22 out from between the two supporting blocks 24, which is simple to operate.

[0030] The limiting protrusion 22 is provided with an arc surface on the side that contacts the elastic bead 25. The arc surface is matched with the shape of the elastic bead 25 so that when the arc surface of the limiting protrusion 22 contacts the elastic bead 25, the limiting protrusion 22 will not be separated from the elastic bead 25 without being pulled by external force. The limiting protrusion 22 and the fixing plate 21 are integrally formed. The limiting protrusion 22 and the fixing plate 21 form a T-shaped structure, and both ends of the fixing plate 21 are provided with mounting holes 27 for connection with the face cover 1.

A clearance hole is provided at one end of the cavity for one end of the ball 253 to pass through and contact with the side wall of the limiting protrusion 22. The diameter of the clearance hole is slightly smaller than the diameter of the ball 253 to prevent the ball 253 from escaping from the cavity and affecting the clamping effect of the limiting protrusion 22. An adjustment mechanism for adjusting the clamping force of the ball 253 is provided at the other end of the cavity. The spring 252 makes the ball 253 have a certain elasticity. When the limiting protrusion 22 contacts the ball 253, the limiting protrusion 22 uses the ball 253 to provide the spring 252 with a reverse force to compress the spring 252, and uses the rebound force of the spring 252 to provide the ball 253 with a clamping force, so as to clamp and fix the limiting protrusion 22.

[0032] The adjustment mechanism includes an adjustment block 251, the side wall of which is provided with an external thread section, and the other end of the cavity is provided with a screw hole 254 for the adjustment block 251 to be screwed, and a slot is provided at the end of the adjustment block 251 away from the screw hole 254. The slot is convenient for rotating the adjustment block 251 with the help of a tool to adjust the length of the adjustment block 251 entering the screw hole 254, thereby providing a compression force to the spring 252 through the adjustment block 251, so as to facilitate adjusting the elastic coefficient of the spring 252 according to actual installation requirements, thereby adjusting the clamping force between the two elastic beads 25.

[0033] The corners of the upper ends of the support blocks 24 are all set to arc angles, and countersunk holes 26 for connecting with the bottom shell 3 are opened at both ends of the bumper clamp seat 23. The countersunk holes 26 are convenient for fixing the bumper clamp seat 23 on the bottom shell 3 in advance, which brings convenience to the assembly of the bottom shell 3 and the cover 1 of the keyboard.

The TYPC interface 5 is magnetically adsorbed to the circuit board in the keyboard through the PIN magnetic connector 8. A cavity for installing the PIN magnetic connector 8 is provided at the bottom of the bottom shell 3, and a magnetic protection cover 6 for protecting and limiting the PIN magnetic connector 8 is detachably installed at the cavity mouth of the cavity. The circuit board is electrically connected to the TYPC interface 5 through the PIN magnetic connector 8, which avoids the traditional need to use wires to connect the circuit board to the TYPC interface 5, thereby improving the convenience of connecting the circuit board to the TYPC interface 5.

[0035] A counterweight plate 7 is also embedded in the lower surface of the bottom shell 3. The counterweight plate 7 is provided with a recess for installing the magnetic protection cover 6. The arrangement of the matching plate improves the stability of the keyboard during use.

[0036] The PIN magnetic connector 8 includes a magnetic male seat 81 fixed to the circuit board in the keyboard and a magnetic female seat 84 installed on the bottom shell 3. The magnetic male seat 81 and the magnetic female seat 84 are magnetically adsorbed together. The magnetic female seat 84 is fixed inside the cavity through a support frame 83, and a receiver 82 is arranged between the bottom shell 3 and the support frame 83. One side of the magnetic female seat 84 is connected to the TYPC interface 5. The receiver 82 is used to realize wireless communication of the keyboard. Through the magnetic connection between the magnetic male seat 81 and the magnetic female seat 84, the circuit board and the TYPC interface 5 can be quickly electrically connected and disassembled, thereby improving the convenience of installing and disassembling the circuit board.

[0037] The utility model relates to a quick-release structure of a keyboard, including a face cover and a bottom shell, wherein the face cover and the bottom shell are detachably connected by a quick-release bead structure. The quick-release bead structure provides a simple connection method for the face cover and the bottom shell, allowing users to quickly disassemble and assemble the keyboard, and the disassembly process is very smooth compared to the snap-on structure. The PCB board of a traditional keyboard is connected to other components in the bottom shell by a cable, and the face cover and the bottom shell need to be particularly careful during the initial disassembly, otherwise the connecting components or the cable will be damaged. In order to achieve complete and extreme quick release, the PCB board and the TYPC interface in the keyboard are connected through a PIN magnetic connector, which is an interface technology that uses magnetic force to achieve quick connection and disconnection. The PIN magnetic connector usually consists of two parts: a magnetic male seat 81 is a magnetic PIN (pin), and a magnetic female seat 84 corresponds to the magnetic socket. When the two are close, the magnetic force will cause them to automatically align and connect together. The quick-release bead structure and the PIN magnetic connector achieve complete and extreme quick release of the keyboard.
