[0002] With the continuous development of computer mouse, it brings more imagination and operation experience to gamers, office and home users, and users also have more and more requirements. For example, the left and right covers will be out of sync after using for a while. Users can clearly feel that the feel of the cover is not as good as before, such as the inconsistency of the pressing height of the left and right buttons, the inconsistency of the rebound force of the left and right buttons, the inconsistency of the trigger time of the left and right buttons, and the phenomenon of stagnation and adhesion. At the same time, when the user operates the mouse for a long time, the button part is a consumable part. If it is only repaired because of the button part, it will greatly increase the user's repair cost and repair time. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: the utility model relates to a mouse switch contact point adjustment structure, including a base, a support plate, a PCBA assembly and a pair of cover plates, the support plate is installed on the base and covers the base, the PCBA assembly is arranged on the base and is located between the base and the support plate, the PCBA assembly is provided with a pair of switch contacts, the cover plate is installed through the support plate and is arranged facing the switch contacts, an adjustment sheet is provided between the cover plate and the switch contacts, the adjustment sheet is arranged on the cover plate, the surface of the adjustment sheet facing the switch contacts has a rough surface with concave and convex points, and the surface of the switch contact facing the adjustment sheet is a smooth surface that is smooth relative to the rough surface.

[0005] Preferably, the adjustment sheet and the switch contact have the same material hardness.

[0006] Preferably, a key switch is respectively arranged under the cover plate, and the key switch passes through the support plate and is arranged directly above the switch contact.

[0007] Preferably, the end surface of the push switch is provided with a groove, and the adjustment sheet is installed in the groove.

[0008] Preferably, a key slot is provided on the support plate, and the pair of cover plates are installed in the key slot.

[0009] Preferably, a pair of guide grooves are provided in the key slot, the upper and lower ends of the guide grooves are openings, and the key switch is embedded in the guide grooves and is installed on the support plate.

[0010] The beneficial effect of the utility model is that: in the utility model, a rough surface with concave and convex points is set on the surface of the adjustment sheet facing the switch contact, and a smooth surface that is smooth relative to the rough surface is set on the surface of the switch contact facing the adjustment sheet. When the user knocks on the cover plate, the key switch moves in the direction of the switch contact, and the adjustment sheet collides with the switch contact along with the key switch, and the rough surface of the adjustment sheet collides with the smooth surface of the switch contact, so that the switch contact generates a hit signal and transmits it to the PCBA component. Because the material hardness of the adjustment sheet and the switch contact is the same, the rough surface of the adjustment sheet and the smooth surface of the switch contact rub against each other, reducing the friction coefficient of the two surfaces. The actual measurement shows that the service life of the key switch is increased by 5 times. In this way, as time goes by, the structure of the adjustment sheet can remain unchanged, so that the user cannot feel the change of the cover plate, and there is no difference from the initial use, thereby solving the problems of inconsistent pressing height, inconsistent rebound force, inconsistent trigger time and stagnation and adhesion of the left and right cover plates due to wear. At the same time, the thickness of the adjustment sheet of the utility model can have a variety of specifications, and no matter which material the mouse cover is equipped with, the wear problem can be well solved. At the same time, the cover plate of the utility model is divided into a button part, a pressure-bearing part and a fixing part, which can be detachably assembled on the support plate, and the installation method is simple, and the stability of the overall structure of the mouse is also enhanced. When the user operates the mouse for a long time, the button part is a consumable part. The utility model separates the button part, and the user can replace the cover plate according to the actual situation or needs, thereby greatly reducing the user's maintenance cost and maintenance time.
