Press key structure and key board comprising same

Abstract

The invention provides a press key structure and a key board comprising the same. The press key structure comprises a key cap, a base and a shear-shaped strutting piece arranged between the key cap and the base, wherein the shear-shaped strutting piece comprises an inner frame with a projecting part and an outer frame with a V slot, and the shift of the key cap in the vertical direction can be limited by controlling the clamping of the projecting part and the V slot. The design of the shear-shaped strutting piece can keep the stable movement of the key cap and maintain the pressing touch, and in the assembling process of the shear-shaped strutting piece, the inner frame can be assembled to the outer frame without unfurling the outer frame.

Description

technical field [0001] The invention relates to a key structure, in particular to a key structure applied to a keyboard. Background technique [0002] The keyboard is a common input device, including many such as figure 1 The shown button structure 1 is used to trigger a switch after being pressed to generate an electronic signal to be input into the computer. [0003] figure 2 Shown is a three-dimensional exploded view of a conventional button structure 1 . The button structure 1 includes a keycap 11 , a scissor-shaped support member, an elastic member 14 , a membrane switch 15 , and a bottom plate 16 . Wherein, the scissor-shaped supporting member includes an inner frame 12 and an outer frame 13 for connecting the keycap 11 to the bottom plate 16 . The membrane switch 15 is disposed on the bottom plate, and the elastic member 14 is disposed between the keycap 11 and the membrane switch 15 for triggering the membrane switch 15 to generate an electronic signal when the ...

Problems solved by technology

Since the shaft 121 and the shaft hole 131 must be closely engaged, the keycap 11 can be kept stable and not easy to shake during the process of being pressed and reset, but the design of the tightly engaged shaft 121 and the shaft hole 131 often However, it causes the inner frame 12 and the outer frame 13 to generate excessive friction force during mutual rotation, which affects the tactile feeling when the user presses the keycap 11

As the keycap 11 is pressed more times, the shaft 121 of the inner frame 12 and the shaft hole 131 of the outer frame 13 cannot be tightly engaged due to friction, which eventually causes the keycap 11 to be unstable and easy to press. Shaking problem arises
