Description

Keyboard press button structure

Technical field

A kind of keyboard press button structure is the utility model is related to, more particularly to a kind of key for improving keycap surrounding pressing feel Disk press-key structure.

Background technology

Traditional keyboard press button structure, it includes keycap 1, scissors bindiny mechanism 2, conducting wire plate 3 and bottom from top to bottom Plate 4, in addition to elastomer 8, the top of elastomer 8 pass the axis hole of scissors bindiny mechanism 2, abutted with keycap 1, bottom and conductor wire Road plate 3 abuts；Such as Fig. 1 a, elastomer 8 generally corresponds to the centre position of keycap 1, when pressing the centre position of keycap 1 to bottom, Because cushioning effect be present in elastomer 8, between scissors bindiny mechanism 2 and keycap 1 between conducting wire plate 3, with bottom plate 4 it Between contact be not hard collision, feel is more comfortable.

But when pressing keycap surrounding, such as Fig. 1 b~1c, scissors when Fig. 1 b and 1c show pressing keycap surrounding to bottom The mated condition of bindiny mechanism 2 and each part, such as Fig. 1 b, wherein, housing and the keycap 1 of scissors bindiny mechanism 2 are piled up, Inside casing is piled up with conducting wire plate 3；Fig. 1 c can be seen that the scissors inside casing of scissors bindiny mechanism 2 and scissors housing touches Hit together, and the housing of scissors bindiny mechanism 2 is piled up with bottom plate, i.e. scissors bindiny mechanism 2 and keycap 1, conductor wire 4 equal direct collision of road plate 3 and bottom plate, without cushioning effect so that pressing feel is poor.

Utility model content

Purpose of utility model：Feel is poor when the utility model is directed to pressing keycap surrounding in conventional keys structure asks A kind of topic, there is provided keyboard press button structure.

Technical scheme：Keyboard press button structure described in the utility model, it includes keycap, scissors connection machine from top to bottom Structure, conducting wire plate and bottom plate, portion is conformed between scissors bindiny mechanism and conducting wire plate, presses keycap surrounding any bit Put, first contact the jut between scissors bindiny mechanism and the conducting wire plate or bottom plate that are disposed below, continue to press, press The scissors bindiny mechanism of point side contacts using the jut as fulcrum flexural deformation with conducting wire plate.During whole pressing, Direct collision is not present between scissors bindiny mechanism and each part, user's feel is preferable.

Preferably, jut is arranged on bottom plate, and the protruding end of jut passes conducting wire plate；More excellent, projection Portion and bottom plate integrally connected, protrude to be formed from backplate surface to keycap side.

Jut is also disposed in scissors bindiny mechanism；Further, scissors bindiny mechanism includes scissors inside casing and scissors Housing, jut may be disposed on the scissors inside casing and/or scissors housing；Further, jut and scissors bindiny mechanism Integrally connected, it can protrude to be formed to bottom plate side from scissors inside casing or scissors housing surface.
