Abstract
The utility model discloses a kind of key switch pressing structure, including button, the swing rod being connected with button, the microswitch of wiring board and installation in the circuit board, it is characterised in that：Offset plate is additionally provided with the wiring board, the opening position that microswitch is corresponded on the offset plate is provided with frustum structure, and the frustum structure abuts against with swing rod；During work, swing rod presses adhesive sheet, then presses microswitch by offset plate and realize corresponding function.The utility model sets frustum structure by enclosing offset plate on microswitch on offset plate, and cylinder boss structure is set on swing rod.During work, swing rod presses adhesive sheet, then power is transferred into microswitch by offset plate, and then realizes corresponding function.The utility model has better operating handle than prior art, and structure is novel simple, and operation is comfortable, service life length.
Description
Technical field
The utility model belongs to vehicle switch technical field, more particularly to a kind of automobile key switch pressing structure.
Background technology
Current key switch is widely used in automobile manufacturing process, and common key switch has a variety of specific knots
Structure, there are lever, moving seesaw-type etc. ... ... with respect to similar-type products, typically pass through key press microswitch or pressing conducting resinl
Plate, so as to realize switching function and operating handle, but this class formation often has that toggle feel is bad and performance is bad asks
Topic.Therefore, how to be switched to existing with less cost improvement to overcome foregoing problems, turn into this area technology urgently to be resolved hurrily
Problem.
Utility model content
To overcome above-mentioned technical problem, the utility model provides a kind of key switch pressing structure, solves existing switch
Existing precompressed deficiency, operating handle is poor, sound is big, the insecure problem of performance.
Technical scheme is used by the utility model solves its technical problem：
A kind of key switch pressing structure, including button, the swing rod being connected with button, wiring board and installed in circuit
Microswitch on plate.Wherein, offset plate is additionally provided with wiring board, the opening position that microswitch is corresponded on the offset plate is provided with cone
Platform structure, the frustum structure abut against with swing rod.During work, swing rod presses adhesive sheet, then presses microswitch by offset plate and realize
Corresponding function.Using as above technical scheme, by enclosing offset plate on microswitch surface, key press offset plate, pass through offset plate again
Pressing microswitch realizes function, has good operating handle so that switching manipulation is comfortable, dependable performance, meets client's need
Ask.
To ensure that frustum structure has more preferable pressing force, further, it is recessed in the frustum structure of offset plate to be additionally provided with one
Portion, swing rod are provided with the cylinder boss structure being engaged with recess at its pressing with offset plate.
Cylinder boss structure and the pressing mode of offset plate press for point.Because offset plate is attached on microswitch, use is foregoing
The scheme of point pressing, on the one hand make it that operation is more comfortable, on the other hand can also effectively reduce noise.
In addition, to ensure that swing rod contacts with the effective of offset plate, while stroke is reduced, have between swing rod and offset plate
0.2mm precompressed.
The beneficial effects of the utility model：
The utility model sets frustum structure by enclosing offset plate on microswitch on offset plate, is set on swing rod
Cylinder boss structure.During work, swing rod presses adhesive sheet, then power is transferred into microswitch by offset plate, and then realizes corresponding work(
Energy.The utility model has better operating handle than prior art, and structure is novel simple, and operation is comfortable, uses
Long lifespan.
Below with reference to drawings and examples, the utility model is described in detail.
Brief description of the drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is sectional view of the present utility model.
Fig. 3 is Fig. 2 partial enlarged drawing.
Embodiment
Embodiment,
Also referring to Fig. 1 to 3, a kind of key switch pressing structure 101, including button 5, swing rod 4, wiring board 1, fine motion
Switch 3 and offset plate 2.
Wherein, swing rod 4 is connected with button 5, and wiring board 1 is installed on case inside wall, and microswitch 3 is fixed on circuit
On plate 1.
Offset plate 2 is covered on wiring board 1, and the opening position that microswitch 3 is corresponded on offset plate 2 is provided with frustum structure 6, pendulum
There is 0.2mm precompressed between bar 4 and offset plate 2.It is additionally provided with a recess 7 in frustum structure 6, swing rod 4 is in its pressing with offset plate 2
The cylinder boss structure 8 being engaged with recess 7 is provided with pressure.
Because offset plate 2 is attached on microswitch 3, cylinder boss structure 8 and the pressing mode of offset plate 2 press for point, a side
Face may be such that operation is more comfortable, on the other hand can also effectively reduce noise.
The utility model is pressed by adhesive sheet, again by offset plate first by enclosing offset plate, swing rod on microswitch surface
Microswitch realizes function, has good operating handle than prior art, while has that operation is comfortable, dependable performance it is excellent
Point, has better met customer demand.
Described above is only to preferred embodiment of the present utility model, and not the scope of the utility model is defined,
Therefore on the premise of the utility model design spirit is not departed from, those of ordinary skill in the art are to structure described in the utility model
Make, the equivalence changes that feature and principle are made or decoration, all should fall into the scope of protection of the utility model.
