Under the normal use condition, the electromagnetic structure is electrified, the attraction clamping groove 48 is close to, the third fixing plate 43 extends into the fixing groove 40 under the action of the sixth spring 49 and does not correspond to the position of the through groove 41, if the protection plate 4 is close to the upright post 2 at the moment, the first wedge-shaped plate 45 cannot be pushed back into the clamping groove 48 when rotating to the position of the through groove 41, and the upright post 2 and the base 1 are still in a fixed connection state.

When only one of the protection plates 4 is close to the upright post 2, the second rotary ring 44 can be pushed to rotate, so that all the third fixing plates 43 are pressed back into the clamping grooves 48, and the upright post 2 is disconnected from the base 1.

When the vehicle is impacted, impact force is absorbed by the anti-collision plate 6 and the sliding plate 5 to slow down the impact force of the vehicle, if the vehicle can stop moving at the moment, equipment is not damaged and personnel are not injured, the anti-collision plate 6 is impacted and deformed at most, the maintenance cost is low, and the normal use of a charging pile is not influenced; when the anticollision board 6 can not prevent that the vehicle from continuing to be close to stand 2, anticollision board 6 directly breaks away from the equipment main part, the outside guard plate 4 of vehicle promotion stand 2 is close to stand 2 this moment, guard plate 4 continues to absorb the impact force under the effect of guard plate buffer gear, when pneumatic cylinder 18 compresses to the limit still can not make the vehicle stop, stand 2 breaks away from in the base 1, when the vehicle striking is on stand 2, with stand 2 collision from its initial position, the electric pile of filling of vehicle striking is the movable object rather than fixed building, avoid the vehicle impaired too big, avoid the vehicle to fill electric pile striking damage simultaneously, after will filling electric pile and hit to fly, because guard plate buffer gear and guard plate 4's existence, it is less impaired when filling electric pile and dropping.

Protection plate 4 passes through screw fixed connection at guide pillar 17 tip, by the striking after through change protection plate 4 can, can be quick restore to fill electric pile, the protection plate 4 that gets off of change is restoreed or is scrapped according to impaired degree, collision guard 6 also comes quick with equipment restoration through the collision guard 6 of more renewing on the same principle, can be quick put into use, when shortening the maintenance usefulness, improve the utilization ratio that fills electric pile.

Compared with the prior art, the invention has the following beneficial effects:

1. the combination of multiple buffering devices is adopted, so that the charging pile is prevented from being collided, the shutdown time of the charging pile is shortened, the working time of the charging pile is prolonged, and the utilization rate of the charging pile is improved;

2. when the charging pile is strongly impacted, the active destructive structure is improved, and the whole structure is not impacted with less loss, so that the maintenance cost is reduced, the maintenance time is shortened, and the cost for using the charging pile is reduced;

3. the damage of the charging pile body is avoided, the damage degree of the vehicle is reduced when the vehicle is impacted, the loss of the vehicle is avoided being aggravated due to the protection of the charging pile, and the loss of the charging pile body and the vehicle can be reduced at the same time;

4. when charging pile is collided away from the original place, no circuit is exposed outside, thereby avoiding causing fire, effectively reducing the damage such as fire caused by accident, and reducing the loss of charging station.
