Description
Technical field
The present invention relates to the improvement of the anticreep safety device of electronlmobil in a kind of electronlmobil.
Background technology
Nowadays, electronlmobil is due to zero-emission, noiselessness, driving low cost and other advantages, the electronlmobil research and development upsurge that one is competed with one another is started all over the world, but it is found that, after a long time use again or when wet weather, the existence power leakage phenomenon more or less of battery, when electronlmobil is in charge condition, leaky particularly outstanding, adds the metal body design being in security consideration, brings no small potential safety hazard to the routine use of electronlmobil.
Summary of the invention
The present invention is directed to above problem, provide a kind of structure simple, can effectively prevent from leaking electricity and cause the anticreep safety device of the electronlmobil of potential safety hazard.
Technical scheme of the present invention is: described electronlmobil comprises vehicle body, wheel, wheel shaft and Manual brake device, and the anticreep safety device of described electronlmobil is socketed on described wheel shaft, and is fixedly connected with described wheel shaft;
The anticreep safety device of described electronlmobil comprises pressure apparatus and some electric installations be connected;
Described pressure apparatus is located between described Manual brake device and described electric installation, and described pressure apparatus is connected with described electric installation.
Described electric installation comprises conduction piston, conduction cylinder chamber ring and extension spring;
Described some conduction cylinder chambeies are connected, and described conduction cylinder chamber outer face is provided with through hole, and described conduction cylinder chamber inner end surface is fixedly connected with described wheel shaft;
Described conduction piston is located in described through hole, and suitable with described through hole;
Described extension spring is located between described conduction piston tail end and described conduction cylinder cavity wall, and is fixedly connected with described conduction piston, described conduction cylinder chamber;
Described conduction piston tail end is provided with spacing ring.
In the present invention, manually brake gear control presssure device carries out pressurization decompression to conduction cylinder chamber, then in conjunction with extension spring, thus realize stretching out and retraction of conduction piston; Put down Manual brake device, conduction piston is retracted, and electronlmobil can normally travel; During pull-up hand-operated brake, conduction piston stretches out also and earth surface, achieves the effect of ground connection, and make electronlmobil when stopping charging, vehicle body ground connection, actv. avoids the potential safety hazard of electronlmobil electric leakage when charging; Simple structure, makes the present invention can use widely in daily production and application process.

Detailed description of the invention
As shown in Figure 1-2, described electronlmobil comprises vehicle body 1, wheel 2, wheel shaft 3 and Manual brake device 4 in the present invention, and the anticreep safety device 5 of described electronlmobil is socketed on described wheel shaft 3, and is fixedly connected with described wheel shaft 3;
The anticreep safety device 5 of described electronlmobil comprises pressure apparatus 51 and some electric installations 52 be connected;
Described pressure apparatus 51 is located between described Manual brake device 4 and described electric installation 52, and described pressure apparatus 51 is connected with described electric installation 52, and manually brake gear 4 can the external pressurization of control presssure device and decompression.
Described electric installation 52 comprises conduction piston 521, conduction cylinder chamber ring 522 and extension spring 523;
Described some conduction cylinder chambeies 522 are connected, and described conduction cylinder chamber 522 outer face is provided with through hole 5221, and described conduction cylinder chamber 522 inner end surface is fixedly connected with described wheel shaft 3;
Described conduction piston 521 is located in described through hole 5221, and suitable with described through hole 5221;
Described extension spring 523 is located between described conduction piston 521 tail end and described conduction cylinder chamber 522 inwall, and is fixedly connected with described conduction piston 521, described conduction cylinder chamber 522;
Described conduction piston 521 tail end is provided with spacing ring 5211, conduction piston can not be stretched out excessive.
The specific embodiment of the present invention as Figure 1-5, electronlmobil stops, pull-up Manual brake device 4, make electric vehicle brake, simultaneously control presssure device 51 pressurizes to conduction cylinder chamber 522, and the pulling force that the piston 521 that makes to conduct electricity shakes off extension spring 523 is outer mobile mutually, until and earth surface, make vehicle body 1 ground connection, like this, just can avoid the potential safety hazard caused because of electric leakage under circumstances by actv.; When electronlmobil starts, put down Manual brake device 4, electronlmobil cancels braking, and pressure apparatus 51 unloads power to the decompression of conduction cylinder chamber 522 simultaneously, and conduction piston 521 resets under the drive of extension spring.
Technique effect of the present invention: the structure optimizing the anticreep safety device of electronlmobil in electronlmobil, makes it more reasonable, and use more simple, convenient, meanwhile, also actv. avoids because of the potential safety hazard caused of leaking electricity.
