Embodiment

For above-mentioned and other purpose, feature and advantage of the present utility model can be become apparent, preferred embodiment cited below particularly, and conjunction with figs. are described in detail below.

Fig. 1 is the structure chart of automobile key device among Fig. 1.The automobile key device is arranged on the control panel, comprises key body 11, button cap 12, circuit board 13 and elastic conduction switch 14.Button cap 12 is installed on the key body 11.Elastic conduction switch 14 is arranged at key body 11 belows and is positioned at circuit board 13 tops, and elastic conduction switch 13 contacts with the conductive contact 14a of circuit board 14 under the effect of key body 11 or separates.When key body 11 was pressed, elastic conduction switch 13 contacted with conductive contact 14a, and circuit board 14 sends signal, and when key body 11 was not pressed, elastic conduction switch 13 separated with

conductive contact

14a, and 14 of circuit boards do not send signal.

Fig. 2 is the vertical view of the key body of automobile key device among Fig. 1.In the utility model, the automobile key device also comprises lid 15, and key body 11 and button cap 12 are to be embedded in the lid 15, and the side of key body 11 also has guiding rib 111, guiding rib 111 matches with groove (not marking among the figure) on the lid 15, has guaranteed the stroke of whole button.Key body 11 bottoms have the salient point of pushing 112 and are combined together the transmission effect of electricity when having realized operation push-button with elastic conduction switch 13.

Fig. 3 .1 is the connection diagram of the button cap and the key body of automobile key device among Fig. 1.Shown in Fig. 2 .1, button cap 12 is connected by buckle 113 with key body 11.

Fig. 3 .2 is the schematic diagram of the light conductor of automobile key device among Fig. 1.Light conductor 16 has the first end 16a and the second end 16b, and wherein the first end 16a is for being arranged at the top of backlight on the circuit board 14 (not marking among the figure), and the second end 16b passes key body 11 and is embedded in the button cap 12.In order to make light conductor 16 leaded lights even, the shape the first end 16a of light conductor 16 makes sawtooth can guarantee that like this leaded light is even.

In the present embodiment, light conductor 16 adopts the PC colourless transparent material to make, and button cap 12 adopts the ABS-777B whitish translucent material to make.Also has pattern 122 on the button cap 12.

In the present embodiment, elastic conduction switch 13 is the electric silica gel key switch, adopts the mode of interference fit to be connected with circuit board 14, connect closely, and the quality of silica gel is softer, has so guaranteed promptly that elastic conduction switch 13 and circuit board 14 combine closely the feel when having guaranteed button again.

Concrete case study on implementation only is a preferable case study on implementation of the present utility model described in the utility model, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be as technology category of the present utility model.
