Problems solved by technology

[0004] However, the elastic rubber 13 is made of rubber material. After a long period of use, the elastic rubber 13 is repeatedly pushed and deformed, and then returns to its original shape from the deformed state, so that the elastic rubber 13 made of rubber material deteriorates or is damaged. Instead, new elastic rubber must be replaced

Embodiment Construction

[0064] In view of the defects of the prior art, the present invention provides a key structure that can solve the problems of the prior art. Multiple key structures form a keyboard device, and the present invention is only described for a single key structure. see image 3, which is a schematic side view of the key structure of the present invention in the first preferred embodiment. The button structure 2 includes a bottom plate 20 , a switch circuit board 21 , a button cap 22 , a frame 23 , a connecting element 24 and a buffer member 25 . The bottom plate 20 is connected to the connection element 24 , and the bottom plate 20 includes a first fixing structure 201 and a second fixing structure 202 . The first fixing structure 201 and the second fixing structure 202 are disposed on an upper surface 203 of the bottom plate 20 . The switch circuit board 21 is disposed on the base plate 20 to be triggered by the keycap 22 to generate a key signal. The switch circuit board 21 inc...

Abstract

Disclosed in the invention is a key structure comprising a base plate, a switch circuit board, a key cap, and a frame. The key cap has a magnetic element arranged at the edge of the key cap. The frame has a magnetic coating layer arranged at the frame edge and is below the magnetic element. When the key cap is touched and pressed, the key cap moves and the switch circuit board is triggered to generate a key signal. When the key cap is not touched and pressed, the key cap moves towards the magnetic element based on the magnetic force generated by the magnetic element. Therefore, the key structure can be operated normally without the need of elastic rubber.

Description

technical field [0001] The present invention relates to a key structure, in particular to a key structure applied to a keyboard device. Background technique [0002] Computers have been widely used and filled in the daily life of modern people. Whether it is work or entertainment, computers play a very important role. With the development of the times, computers are evolving, and computer peripherals are also developing. , where the input device is an important bridge between the user and the computer, especially the keyboard device in the input device is more important, so keyboard manufacturers launch keyboard devices that meet various usage needs in response to various usage needs. [0003] The keyboard device is composed of multiple key structures. For the key structure, please refer to figure 1 , which is a structural explosion diagram of the existing button structure. The existing key structure 1 includes a key cap 11 , a scissors-shaped connecting element 12 , an el...
