Problems solved by technology

However, the disadvantage of the known keyboard device is that the design of the elastic conductive member of each key structure is to be pushed to the bottom and then touch the corresponding membrane switch to trigger the corresponding membrane switch. In addition to the slow time point, at the same time, when the corner of the key structure is easily pressed, it is necessary to increase the pressure to trigger the key signal smoothly.

Abstract

The invention provides a key structure and an elastic conduction piece thereof. The key structure comprises a membrane switch, a key cap and an elastic conduction piece. The key cap is arranged above the membrane switch, the elastic conduction piece is arranged between the key cap and the membrane switch, the elastic conduction piece comprises a supporting cover body and a conduction column body, and the conduction column body is connected to the supporting cover body and located in a containing space of the supporting cover body. The conducting column comprises a first abutting portion, a second abutting portion and a concave portion, the concave portion is located between the first abutting portion and the second abutting portion, the second abutting portion surrounds the concave portion, and the concave portion surrounds the first abutting portion. In the process that the key cap descends and moves relative to the membrane switch, the supporting cover body is extruded by the key cap to drive the conduction column body to descend and move, so that the first abutting part and the second abutting part are in contact with the membrane switch, and adsorption force exists between the concave part and the membrane switch.

Description

technical field [0001] The invention relates to the field of input devices, in particular to a key structure and an elastic conducting member thereof. Background technique [0002] With the rapid development of science and technology, the vigorous development of electronic equipment has brought a lot of convenience to human life. Therefore, how to make the operation of electronic equipment more humane is an important issue. Common input devices of electronic devices include mouse devices, keyboard devices, trackball devices, etc., among which keyboard devices can be used by users to directly input characters and symbols to the computer, and thus have received considerable attention. [0003] The keyboard device includes a plurality of key structures, and each key structure mainly includes a keycap, a scissor-type connecting element, a thin-film circuit board, and a support plate that are stacked in sequence. A backlight module is provided. Specifically, a membrane switch i...
