Keyboard key structure

Abstract

The invention relates to a keyboard key structure. The keyboard key structure comprises a supporting substrate, an electronic circuit board and a keycap, wherein the keycap can move vertically and forms a containing space along with the electronic circuit board, an elastic part is arranged in the containing space, a first conductive piece is arranged on the upper plane of the electronic circuit board, and the elastic part is provided with a second conductive piece corresponding to the first conductive piece. When downward action force is applied to the keycap, the containing space is compressed, and the first conductive piece makes contact with the second conductive piece. When no external force is applied to the keycap, the containing space is recovered to an original state, and the first conductive piece is separated from the second conductive piece. The keyboard key structure has only a few components, is simple in structure, reduces moulds and a large amount of labor cost needed in the production process, and lowers the cost for obtaining a keyboard. In addition, the elastic part is arranged in the containing space formed between the electronic circuit board and the keycap, the volume occupied by keys can be effectively reduced, and meanwhile the keyboard key structure is suitable for manufacturing of the keyboards of a desktop computer and a notebook computer.

Description

technical field [0001] The invention relates to the field of computer hardware, in particular to a keyboard key structure. Background technique [0002] The keyboard is the most common computer input device. It is widely used in microcomputers and various terminal equipment. Computer operators input various instructions and data to the computer through the keyboard to direct the work of the computer. The operation of the computer is output to the display. Readers can easily use the keyboard and monitor to talk to the computer, modify and edit the program, control and observe the operation of the computer. [0003] The existing key structures mainly include crater structure and X structure. The crater-shaped key structure is usually used in desktop computer keyboards, including keyboard lower cover, flexible circuit board, silicone or spring parts, keycaps, keyboard upper cover and other components; The key structure of the X architecture is usually used in laptop keyboards...

Problems solved by technology

The Chinese invention patent with the patent number ZL201010216997.6 discloses an X-structure button structure, including a substrate, a keycap, a first support member, a second support member, and an elastic member. When the user frequently presses the button structure , it is easy to cause damage to its internal structure, and the keyboard will be scrapped due to failure or damage

The Chinese invention patent with the publication number CN 102243529A discloses a keyboard key device. At least one key limiting post is provided between the keyboard body and the keyboard keys, which can effectively prevent the keyboard from malfunctioning or being damaged due to heavy blows. However, due to the The elastic body is located under the keyboard keys, which increases the space required for the key device, which is not conducive to its application in notebook computer keyboards
