Description
Technical field
The present invention is to be related to the field of input unit, more particularly to a kind of key board unit and its scissor connecting element.
Background technology
The input unit of common computer peripheral includes mouse apparatus, key board unit and Trackball device etc., wherein key
Disk device, which is available for users to, directly inputs word and symbol to computer, therefore is quite taken seriously.
Illustrate the structure and function of existing key board unit 1 first, refer to Fig. 1~Fig. 3, Fig. 1 is existing key board unit
Surface structure schematic diagram, Fig. 2 be key board unit shown in Fig. 1 part-structure be in the perspective exploded view at a visual angle, Fig. 3
The part-structure of key board unit shown in Fig. 1 is in the perspective exploded view at an another visual angle.In order to more clearly illustrate, Fig. 2 with
Single key 10 and related elements structure are only drawn in Fig. 3.Existing key board unit 1 includes multiple buttons 10, button bottom plate 11
And film circuit board 12, and there are the multiple thin film switches 121 for corresponding to multiple buttons 10 on film circuit board 12, and press
Key 10 includes keycap 101, scissor connecting element 102 and elastomer 103, and scissor connecting element 102 is then connected to keycap
Between 101 and button bottom plate 11, and including outer framework 1021 and inner frame 1022, and inner frame 1022 is by its rotating shaft
10221 and be articulated in outer framework 1021, therefore outer framework 1021 can be swung toward each other with inner frame 1022.In addition, elastomer
103 are arranged between keycap 101 and button bottom plate 11, and have top 1031.
Wherein, when being moved down when the keycap 101 of any button 10 is touched relative to button bottom plate 11, scissor company
The outer framework 1021 and inner frame 1022 for connecing element 102 can be changed to closed state by folding condition, and the keycap to move down
101 can extrude elastomer 103, support the top 1031 of elastomer 103 and trigger corresponding thin film switch 121, and make
Key board unit 1 produces corresponding push button signalling.And when button 10 is no longer touched, keycap 101 can be in response to elastomer 103
Elastic force and up moved relative to button bottom plate 11, now outer framework 1021 and inner frame 1022 can be changed to by closed state
Folding condition, and keycap 101 can set back.
However, developing because key board unit 1 now has increasingly been towards frivolous direction, button 10 is caused also to reduce
Thickness is just satisfied the demand of ultrathin key board unit 1.However, because the scissor connecting element 102 of button 10 is by moulding
Made by glue material matter, its integral thickness is at most only capable of being reduced to 0.8mm, otherwise will cause the structural strength deficiency of button 10 simultaneously
Influence the stability of support keycap 101.
Therefore, the key board unit that there is now Improvement type is suggested.In the button of Improvement type key board unit, its scissor company
