The present invention comprises a lower cover 1, a middle cover 2, a key cover 3 and a circuit board 4. The circuit board 4 is fixedly arranged on the lower cover 1, and is used for installing components and connecting circuits externally so as to be connected to the terminal. It is also used for installing optical sensing devices for moving the cursor; the middle cover 2 is fixedly arranged on the lower cover 1, and the inner hollow of the middle cover 2 is used for installing the circuit board 4, and the middle cover 2 can limit and protect the circuit board 4, thereby ensuring the stability of the structure and reducing the influence of the outside world; the rear end of the key cover 3 is connected to the rear end of the middle cover 2, and there is a gap between the front end of the key cover 3 and the front end of the middle cover 2, that is, the front end of the key cover 3 can be pressed, and a separation seam is arranged at the front end of the key cover 3 to avoid linkage when clicking left and right, thereby performing a clicking action; pressing columns are arranged at the lower part of both sides of the front end of the key cover 3 5 is used to press the switch contact 6 arranged on the circuit board 4, so when the front sides of the key cover 3 are pressed, a click action is performed, and a pressure groove 7 is provided on the pressing column 5, and a pre-pressing sheet 8 is provided on the middle cover 2. The free end of the pre-pressing sheet 8 is in the pressure groove 7 and is bent downward and tilted to press against the groove surface of the pressure groove 7, thereby generating a downward pressing force on the pressing column 5, forcing the lower end of the pressing column 5 to approach the switch contact 6, thereby shortening the distance between the pressing column 5 and the switch contact 6, thereby reducing or eliminating the empty stroke during the click action, enabling the terminal to quickly receive input signals during use, and improving the user experience; in addition, a roller groove is provided in the middle of the key cover 3 and the middle cover 2 for installing a roller, and a light-transmitting groove is provided on the lower cover 1 for the optical sensor to sense movement. As can be seen from the above, the overall structure of the present invention is simple, reducing or eliminating the empty stroke effect of pressing, thereby providing users with a better user experience.

[0022] In this embodiment, the pre-compression sheet 8 includes an integrally formed fixed transverse section 81 and a pre-compression vertical section 82. The fixed transverse section 81 is arranged on the lower side of the front end of the middle cover 2, one end of the pre-compression vertical section 82 is connected to the fixed transverse section 81, and the other end of the pre-compression vertical section 82 is inclined downward and extends into the pressure groove 7 and rests against the bottom of the pressure groove 7. The pre-compression sheet 8 includes a fixed transverse section 81 and a pre-compression vertical section 82, and the fixed transverse section 81 and the pre-compression vertical section 82 are integrally formed and connected in a T-shape. The fixed transverse section 81 is fixed to the lower side of the front end of the middle cover 2, and one end of the pre-compression vertical section 82 is connected to the fixed transverse section 81, and the other end of the pre-compression vertical section 82, i.e., the free end, is located in the pressure groove 7. Since the free end of the pre-compression vertical section 82 is tilted and bent downward, it can rely on its own structural characteristics to exert a downward pressure on the pressure groove 7, thereby exerting a pre-compression effect on the pressing column 5, shortening the distance between the pressing column 5 and the switch contact 6, thereby reducing or eliminating the empty travel effect during the clicking action, so that the user's operation can be input into the terminal faster, thereby improving the response rate.

[0023] In this embodiment, both sides of the front end of the middle cover 2 are provided with a clearance opening 9 that cooperates with the pressing column 5, the pre-compression piece 8 is arranged on the rear side of the clearance opening 9, and both sides of the rear end of the middle cover 2 are provided with a locking groove 10, and both sides of the rear end of the button cover 3 are provided with a clamping vertical bar 11, and the lower end of the clamping vertical bar 11 passes through the locking groove 10 and is provided with a barb to buckle with the middle cover 2. The clearance opening 9 is used to give way to the pressing column 5 for installation and movement, and the clearance opening 9 is larger than the pressing column 5, so that the pressing column 5 can move within its range. During installation, since the pre-compression sheet 8 needs to extend into the pressure groove 7, the pressing column 5 needs to be sent forward a distance and then retreated during the installation process to ensure that the pre-compression sheet 8 is in the pressure groove 7. Therefore, the existence of the clearance opening 9 and its width greater than the pressing column 5 are indispensable; the engaging through grooves 10 are provided on both sides of the rear end of the middle cover 2 for cooperation with the clamping vertical bars 11 arranged on both sides of the rear end of the button cover 3, so that the rear end of the button cover 3 can be connected to the middle cover 2 for fixation, and the clamping vertical bars 11 are engaged with the middle cover 2 in a barb manner, so it is more convenient during installation or disassembly.

[0024] In this embodiment, a locking strip 12 is provided at the rear side of the clearance opening 9, and the locking strip 12 is located on one side of the pre-compression sheet 8, and the locking strip 12 cooperates with the pressure groove 7. The locking strip 12 is used to lock the pressure groove 7, so that the pressing column 5 is limited in the upward movement stroke, thereby preventing the key cover 3 from being deformed too much and warping up, and the locking strip 12 can also work together with the clamping vertical strip 11 during installation to play a fixing role, preventing the key cover 3 from falling off.

[0025] In this embodiment, both sides of the front end of the middle cover 2 are provided with mounting protrusions 13, and threaded holes are provided on the mounting protrusions 13. The fixing transverse section 81 is provided on the mounting protrusions 13 by the cooperation between the fixing screws 14 and the threaded holes. In addition to being fixed by screws, the fixing transverse section 81 can also be fixed by hot melting, snap fasteners, etc.

[0026] In this embodiment, positioning columns 15 are provided on both sides of the mounting protrusion 13, and two positioning columns 15 are located on both sides of the threaded hole, and positioning holes 16 adapted to the two positioning columns 15 are provided on both sides of the fixed transverse section 81. The two positioning columns 15 can be used to position the pre-compression sheet 8, thereby avoiding the pre-compression sheet 8 from being rotated during installation, and facilitating installation.

[0027] In this embodiment, the lower end of the pressing column 5 is provided with an upper contact 17 that matches the switch contact 6. Through the upper contact 17, the switch contact 6 can be better triggered when the user clicks, thereby achieving rapid input.

[0028] In this embodiment, the pre-pressed sheet 8 is a metal pre-pressed sheet, which includes a structure of metal materials such as copper sheet, aluminum sheet, stainless steel, etc., and other materials with elastic deformation capability can also be used.

[0029] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
