Key assembly and application equipment thereof

Abstract

The invention relates to the field of operation equipment and discloses a key assembly. The key assembly comprises a silica gel layer, a piezoelectric ceramic membrane, a key shell, a permanent magnet, an electromagnet and a buzzer, the piezoelectric ceramic membrane is positioned between the silica gel layer and the key shell; the permanent magnet is adsorbed on the inner wall of the key shell; an electromagnet is arranged at the corresponding position below the bottom face of the permanent magnet and is of an annular structure, a cylindrical rod perpendicular to the middle of the bottom faceis arranged at the bottom of the permanent magnet, and the bottom end of the cylindrical rod penetrates through a through hole in the middle of the electromagnet and corresponds to a contact switch below the electromagnet. The permanent magnet is attracted to the inner wall of the key shell, rebounding of the key shell is achieved through repulsion of the electrified electromagnet and the permanent magnet, the paragraph hand feeling of the key is achieved instead of completely depending on an internal spring and key shell materials, the paragraph hand feeling of the key can be kept for a longtime, and rapid clicking and long-time use are met.

Description

technical field [0001] The invention relates to the field of operating equipment, in particular to a key assembly and its application equipment. Background technique [0002] The mouse is an auxiliary peripheral device that can be used during the operation of the computing frame. Generally, the computer includes two buttons on the left and right and a scroll wheel located in the middle of the button. The material between the switch contact and the button is limited, and the service life is limited. Users who use the mouse frequently will fail after 3 to 4 months of use. [0003] According to the product provided by the patent document CN104681337B, it is known that the product is displaced after being pressed by a spring, and the displacement is converted into an electrical signal by the displacement monitoring mechanism and the displacement judging device, and the electrical signal is sent to the peripheral circuit.

[0002] The mouse is an auxiliary peripheral device that can be used during the operation of the computing frame. Generally, the computer includes two buttons on the left and right and a scroll wheel located in the middle of the button. The material between the switch contacts and the buttons is limited, and the service life is limited. Users who use the mouse frequently will fail after 3 to 4 months of use.

[0003] According to the product provided by the patent document CN104681337B, it is known that the product is displaced after being pressed by a spring, and the displacement is converted into an electrical signal by the displacement monitoring mechanism and the displacement judging device, and the electrical signal is sent to the peripheral circuit. The spring force is The main force of jacking up the key top, and the elastic force of the spring will also be limited by the material of the spring itself, and the phenomenon of material fatigue and elastic decline will also occur. Even with the adsorption effect of the magnet, after the elastic decay, the displacement distance under the pressure There will be changes; at the same time, a sound-absorbing layer is set on the lower limit device to achieve sound-absorbing, but sound and silence can only be set at the time of manufacture, and once the user purchases it, it can only be set by disassembling the mouse, and cannot be automatically switched

[0004] According to the product provided by the patent document CN201510602347.8, it can be seen that it provides a mouse with touch buttons, which uses touch buttons to replace traditional mechanical buttons, greatly prolonging the service life of the mouse, but the touch buttons have no paragraph feel , used for a long time, it is easy to cause hand fatigue, not suitable for fast clicking and long-term use
