In the power connection shockproof protection structure for the electric vehicle, the expansion layer is in an annular structure and is positioned on the outer side of the conducting strip, and the expansion layer is made of expandable rubber materials.

Compared with the prior art, the invention has the advantages that:

1. according to the invention, through the arrangement of the structures such as the sucking disc and the connecting pipe, when the battery wire is inserted into the connecting port, the sucking disc is squeezed, so that the sucking disc moves towards the inner side of the slot, and gas in a sucking disc cavity in the sucking disc is sucked into the cavity, and the effect of negative pressure fixation is realized. Therefore, the plug can be sucked into the deepest part of the slot by the sucker all the time, and the connection stability is ensured in the using process;

2. a sucker cavity is formed in the sucker and is communicated with the air suction cavity in the connecting rod through a connecting pipe through a one-way valve, so that when the connecting rod and the sliding block are pressed to move towards one side far away from the slot, the fixed block in the air suction cavity moves towards one side close to the plug relative to the air suction cavity, and air on the other side is pumped out, so that greater negative pressure exists in the sucker cavity of the connecting pipe box, and the effect of stably fixing the sucker and the plug is realized;

3. when the road surface is poor, the plug can generate small-amplitude displacement under the action of vibration, and the sucking disc and the conducting strip in the plug can slide together, and in the invention, the shaking of the plug can make the small metal balls in the expansion cavity in the plug move up and down irregularly, and cut the magnetic induction lines generated by the magnetic layer, so that the small metal balls can be used as a heat source to generate electric heat, thus the advantage is that the air pressure in the expansion cavity is increased. The gas enters the expansion layer through the gas guide tube, so that the expansion layer extrudes the conducting strip, and the conducting strip is prevented from sliding out of the socket;

4. the inflation chamber is close to sucking disc one side and is provided with the negative pressure passageway through the check valve intercommunication simultaneously, and after gas entering inflation layer and quick cooling, the inflation chamber will briefly exist a negative pressure, if sucking disc negative pressure effect is relatively poor, under the atmospheric pressure effect, during residual gas in the sucking disc will pass through the negative pressure passageway and get into the inflation chamber to strengthen the fixed effect of sucking disc to the plug in saying.
