When contacting the circuit on bottom plate, circuit is connected;After decontroling keycap, keycap moves under the rebound effect of elastomer to bottom plate negative direction
Dynamic, conduction column leaves bottom plate, and circuit disconnects.
After laying LED light on bottom plate, LED, which shines, provides light source, thus constitutes backlight keyboard construction.
Preferably, scissor mounting hole is opened up on bottom plate, which can be clear opening or stepped hole.
The bottom of scissor is fixed to by fixing piece in the scissor mounting hole, it is preferred that and fixing piece is plastic parts, this
When plastic parts can be molded by Shooting Technique it is fixed-type in scissor mounting hole;It can also be equipped in plastic parts bottom
Hot molten column, the hot molten column are fixed to by hot melting process in scissor mounting hole.
The bottom plate of the utility model can be pcb board, wherein pcb board is also known as printed circuit board, can also select metal
Plate, PC plate (i.e. polycarbonate plate) or glass-fiber-plate etc..In addition, elastomer is preferably silica gel or metal clips.
Advantageous effect:Compared with prior art, it the utility model proposes a kind of completely new keyboard structure, is substituted with bottom plate
Support plate in traditional structure and conducting wire plate, while cancelling backlight module, light emitting diode is directly arranged on bottom plate, key
Consolidation body thickness is thinning, and material category is reduced, and store keeping, simplified manufacturing process is convenient for reduce keyboard cost.

Specific implementation mode
The technical solution of the utility model is described further below in conjunction with the accompanying drawings.
The keyboard structure of the utility model, including bottom plate 1, scissor 2, elastomer 3 and keycap 4, as shown in Figure 6, wherein
Bottom plate 1 is pcb board (i.e. printed wiring board), can also select metallic plate, PC plate or glass-fiber-plate etc.;Scissor 2 is outer by one
Scissor 201 and interior scissor 202 intersect composition, wherein and outer scissor 201 and interior scissor 202 are frame structure,
They are fixed between bottom plate 1 and keycap 4.It is equipped with card slot, the top of outer scissor 201 and interior scissor 202 in 4 bottom of keycap
Portion is stuck in the card slot.Scissor mounting hole 101 is opened up on bottom plate 1, which can be clear opening, such as Fig. 1
Can also be stepped hole, as shown in Figure 2 and Figure 4 shown in Fig. 3.The bottom of outer scissor 201 and interior scissor 202 passes through solid
Part 102 is determined fixed in the scissor mounting hole 101, fixing piece 102 selects plastic parts, and there are two types of fixed forms at this time, the
Fixed-type in scissor mounting hole 101 one is plastic parts is molded by Shooting Technique, second is at plastic parts bottom
Portion is equipped with hot molten column 103, and hot molten column 103 is fixed to by hot melting process in scissor mounting hole 101, as shown in Figure 3-4.
The elastomer 3 of the utility model can be silica gel, can also be metal clips, elastomer 3 by it is a pair of respectively with bottom
302 composition of lower support 301 and upper support that plate is connected with keycap, wherein support is trench structure up and down, and trench structure includes cross
The stabilizer blade 304 in portion 303 and both sides, the transverse part 303 supported up and down link together, it is upper support 302 stabilizer blade 304 upwardly extend with
4 bottom of keycap is fixed, and the stabilizer blade 304 of lower support 301 is extended downwardly to be fixed with bottom plate.It is horizontal that conduction column 305 is fixed on lower support 301
The lower section in portion 303 will not contact vacantly in the top of bottom plate 1 with bottom plate 1 under normal circumstances, after pressing keycap, conduction column 305
It is moved to bottom plate direction, line conduction is realized by the circuit in contact base plate.
The utility model lays circuit 5 on bottom plate by the techniques such as etching, printing, and is corresponded in 3 conduction column 305 of elastomer
Bottom plate position on lay circuit positive and negative anodes contact point, when conduction column 305 contact the positive and negative anodes contact point when circuit connect, when
