Abstract
The utility model provides a can change button structure of stroke, includes silica gel key and the compound lever of compriseing first lever and second lever, and the point of application of force of first lever is the button, and the stress point of first lever is as the point of application of force of second lever, the stress point and the silica gel key adaptation of second lever. Its advantage is the proportion that stroke (A) yu the silica gel key stroke (B) of button were controlled to 1. Arm of force proportions (L1L2) that can design the different length of lever, 2. Button stroke (A) and silica gel key effective stroke's (Y) proportion is controlled to the shape that can adjust compound lever contact point department to control button stroke (A) and silica gel key's stroke (B) proportion.
Description
Technical field
The utility model relates to having and is suitable for unidirectional pushing away, drawing and the movable member of the switch of moving linearly operation part; And dress contact thereon, hold and refer to a kind of press-key structure changing stroke.
Background technology
The press-key structure of existing a lot of electronic product, comprises a lever and silica gel push-button, and lever comprises thick stick body, hinging supporting shaft, keycap (point of application) and pressure spot (stress point), pressure spot and silica gel push-button adaptation, the break-make of pressing keycap controllable silicon glue button.But known this press-key structure, the Distance geometry pressure spot of keycap and hinging supporting shaft and the distance of hinging supporting shaft are fixing, and same contour structures can not adapt to the different rows range request of keycap, make its versatility poor, and this is its shortcoming.
Summary of the invention
For the shortcoming of prior art, the purpose of this utility model is to provide a kind of press-key structure changing stroke.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of press-key structure changing stroke, comprise silica gel push-button, it is characterized in that: also comprise the compound lever be made up of the first lever and the second lever, the point of application of the first lever is button, the stress point of the first lever as the point of application of the second lever, the stress point of the second lever and silica gel push-button adaptive.
Enter lower step ground, a movable block can be had between described silica gel push-button and the second lever stress point, to make the activity between them more flexible.
The beneficial effects of the utility model are: 1. the arm of force ratio (L1/L2) that can design lever different length controls the stroke (A) of button and the ratio of silica gel push-button stroke (B); 2. can adjust the shape at compound lever contact point place to control the ratio of key stroke (A) and silica gel push-button effective travel (Y), thus control stroke (B) ratio of key stroke (A) and silica gel push-button.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model will be further described.
Fig. 1 is structural representation of the present utility model (button 3 is pressed rear).
Fig. 2 be in Fig. 1 button 3 press before view.
Fig. 3 is the utility model STRUCTURE DECOMPOSITION figure.
In figure: 1 be the first lever fulcrum, 2 be support, 3 be movable block for button, 4 be the second lever, 5 be the second lever stress point, 6 is the second lever fulcrum, 7,8 be silica gel push-button, 9 for pcb board, 10 be the first lever.
Embodiment
See Fig. 1, a kind of press-key structure changing stroke of the utility model, comprise silica gel push-button 8, it is characterized in that: also comprise the compound lever be made up of the first lever 10 and the second lever 4, the point of application of the first lever 10 is button 3, the stress point of the first lever 10 is as the point of application of the second lever 4, and the stress point 5 of the second lever 4 is adaptive with silica gel push-button 8.
When pressing keys 3, when making button 31 rotation around the shaft, the stress point of the first lever 10 pushes down the point of application of the second lever 4, and the second lever 4 is rotated around its rotating shaft 6 under the effect of button 3, its stress point acts on silica gel push-button 8, realizes the function that silica gel push-button is pressed.And the second lever 4 serves the effect becoming stroke.
Be the resistance arm length of the second lever 4 see Fig. 2: L1, L2 is the power arm length of the second lever 4, the stroke A at the contact point place of the first lever 10 and the second lever 4 can be decomposed into X and Y-direction two strokes, and only have the stroke of Y-direction to have effect to silica gel push-button 8, as long as so the shape of we adjustment the first lever 10 and the second lever 4 contact point, just can amount shared by control X and Y decomposition.
The calculating formula of silica gel push-button stroke B is:
B=(L1/L2)*(Y/A)
As can be seen from calculating formula, the adjustment ratio of L1 and L2 and the ratio of Y and A, can realize the object adjusting silica gel push-button stroke B.
In embodiment of the present utility model, between described silica gel push-button 8 and the second lever stress point 5, there is a movable block 7, to make the activity between them more flexible.
Claims (2)
1. one kind can change the press-key structure of stroke, comprise silica gel push-button, it is characterized in that: also comprise the compound lever be made up of the first lever and the second lever, the point of application of the first lever is button, the stress point of the first lever as the point of application of the second lever, the stress point of the second lever and silica gel push-button adaptive.
2. the press-key structure changing stroke according to claim 1, is characterized in that: between described silica gel push-button and the second lever stress point, have a movable block.
