Key and keyboard with same

Abstract

The invention relates to a key and a keyboard with the same. The key comprises a keycap, an upper cover, a switch unit electrically connected with a printed circuit board, an actuating part, an elastic part, a first supporting part, a second supporting part and a bottom plate part with first and second connecting structures, a lower cover, an abutting surface and a fixing seat, wherein the upper cover is provided with a sliding groove and sleeves the lower cover to form an accommodation space with the lower cover; the switch unit is arranged on the fixing seat and located in the accommodation space; the actuating part is abutted on the keycap and movably arranged in the sliding groove in a penetration manner; the elastic part is arranged in the accommodation space and abutted on the abutting surface and the actuating part; the first supporting part is movably connected to the first connecting structure and the keycap; the second supporting part is movably connected to the second connecting structure and the keycap; when the keycap is pressed, the actuating part moves downwards to trigger the switch unit; and when the keycap is released, the elastic part drives the actuating part to move upwards to drive the keycap to return. According to the key, the hand feeling of pressing can be improved and the phenomenon of circuit damage or continuous switch triggering due to improper pressing is avoided.

Description

technical field [0001] The present invention relates to a button and its keyboard, especially to a switch unit that uses an elastic arm to slide with the actuator and directly connects the first connection structure and the second connection structure to the lower cover and the abutment surface of the bottom plate. , and the fixing seat is integrally formed to be movably connected with the first support member and the second support member and its keyboard. Background technique [0002] As far as current personal computer usage habits are concerned, the keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Not only that, but all consumer electronic products in daily life or large-scale processing equipment used in the industry need to be equipped with a key structure as an input device to operate the above-mentioned electronic products and processing equipment. [0003] see figure 1 , which is a schematic cross-sectional view of t...

Problems solved by technology

[0004] However, since the switch 15 on the circuit board 14 is triggered by pressing the keycap 12 so that the trigger portion 19 of the elastic member 18 is pressed down, the circuit board 14 and the elastic member 18 will relatively bear relatively large compressive stress, As a result, the pressing feel of the button 1 is not sensitive enough and the service life of the elastic member 18 is affected. Furthermore, if the user presses the button improperly and the circuit board 14 is subjected to excessive compressive stress, the circuit board 14 may be damaged. Permanent deformation occurs, resulting in damage to the circuit of the circuit board 14 or continuous triggering of the switch 15, etc.
