And conductor wire is provided with earth plate 330, conductor wire ground connection is set.
As shown in figure 1, on the basis of above-mentioned embodiment, the elevating mechanism includes being used to rise lifting the bow 300
Rising bow spring 410 and the drop for overcoming the elastic force of rising bow spring 410 and declining the bow 300 bend cylinder
420, the rising bow spring 410 and it is described drop bow cylinder 420 both ends respectively with the chassis 100 and the bow 300
It is be hinged.
During charging, upper framework 200 is forced to rotate by rising bow spring 410, so as to lift bow 300, after charging,
Then start drop bow cylinder 420, make drop bow cylinder 420 drive upper framework 200 to overcome the elastic force opposite direction of rising bow spring 410 to rotate,
So that bow 300 declines.
It is worthy of note that, the marrow of the structure is herein, is used as rising bow by the elastic construction of rising bow spring 410
Power, because the elastic force of elastic construction is all existing all the time, so reaction during rising bow is very sensitive quick；Pass through drop
The air cylinder structure of bow cylinder 420 is used as the power of drop bow, because driving force is larger caused by cylinder, can make framework 200
Elastic force rapidly is overcome so as to rotate, can so greatly shorten the time of drop bow, and drops bow cylinder 420 to pass through electromagnetism
Valve controls, and very simple during use, operability is also very strong.
For the structure of rising bow spring 410 and drop bow cylinder 420 when lifting bow 300 or falling bow 300, speed is also very
It hurry up, by only needing just complete entirely to act within 10 seconds, so save the time that electric car stops charging.
