Technical Field

The invention belongs to the field of new energy, and particularly relates to a charging wire self-retracting type new energy automobile charging pile.

Background

Along with the progress of technology and living standard, the problem of natural environment pollution that human beings rely on to live is also increasing, and in order to solve the environmental pollution problem, new energy automobile replaces traditional fuel oil car and becomes an important measure, and along with the wide use of new energy automobile, the electric pile trade that fills for new energy automobile has also risen thereupon.

At present, charging piles of new energy vehicles generally have the problem that charging wires are too long and inconvenient to store, the charging wires wound and placed randomly bring great trouble to workers, and when the charging device is used, the charging wires need to be pulled out of the charging piles, after charging is completed, the charging wires need to be manually placed back to the charging piles, and great inconvenience is brought to users; because the charging voltage of the charging pile of the electric automobile is high, if the power supply is not switched on, the charging gun is directly plugged into and pulled out of the charging interface of the automobile, contact electric arcs are likely to be generated, and electric shock danger is caused; in addition, new energy automobile has the parking standard problem when charging, and partial vehicle parking position is far away from the position of filling electric pile, leads to the charging wire to excessively pull the fracture, easily causes the damage of charging wire fracture.

Therefore, a charging wire self-retracting type new energy automobile charging pile is provided to solve the problems.

Disclosure of Invention

The charging pile for the charging wire self-retracting type new energy automobile is convenient for charging wires and high in safety performance, and aims to solve the problems that the charging wire is inconvenient to wind and is in electric shock danger.

In order to achieve the purpose, the invention adopts the following technical scheme: a charging wire self-retracting type new energy automobile charging pile comprises a pile body and a charging wire, wherein a sealing box is embedded in the ground on one side of the pile body, a retracting groove is formed in the side wall of the pile body, a vertically arranged retracting wheel is arranged in the retracting groove, a driving cavity is formed in the pile body, a rotating shaft is coaxially and fixedly connected with the lower end of the retracting wheel, the lower end of the rotating shaft extends into the driving cavity, an identification plate is fixedly connected to the upper surface of the sealing box, the identification plate is an elastic plate with the middle part arched upwards, the upper surface of the identification plate protrudes out of the ground, the sealing box is communicated with the driving cavity through an air guide tube, one end, close to the driving cavity, of the air guide tube is arranged along the vertical direction, a sliding plug is connected in the air guide tube in a sealing and sliding mode, a threaded column is rotatably connected to the upper surface of the sliding plug, and a horizontally, run through in the diaphragm and be fixed with a screw thread section of thick bamboo, the screw thread post runs through a screw thread section of thick bamboo and with screw thread section of thick bamboo screw-thread fit, first elasticity electricity connection piece is installed to the upper end of screw thread post, the top surface in drive chamber is equipped with connects the second elasticity electricity connection piece that the piece matches with first elasticity electricity, the screw thread post passes through drive mechanism and is connected with the pivot.

Preferably, the air guide pipe is provided with a flow limiting valve, the flow limiting valve can limit the flow and the flow velocity of air in the seal box entering the air guide pipe, and the situation that the air pressure in the air guide pipe is increased instantly due to the fact that a vehicle is too heavy, so that the first elastic connecting electric piece and the second elastic connecting electric piece are violently collided to cause damage is avoided.

Preferably, the first elastic electricity connecting piece is electrically connected with an external power supply, and the second elastic electricity connecting piece is electrically connected with one end of a charging wire.

Preferably, the transmission mechanism comprises a tooth column coaxially sleeved outside the threaded column, a gear is coaxially installed at the lower end of the rotating shaft, and the gear is meshed with the tooth column.

Preferably, the intercommunication has the blast pipe on the lateral wall in drive chamber, the other end of blast pipe extends to sign board department and sets up, and when the sliding plug rebound under the atmospheric pressure effect, will drive the air extrusion of intracavity and blow through the blast pipe and blow at the sign board surface, blow off the dust on sign board surface, debris, improved the degree of discerning of sign board, the vehicle of being convenient for is normally parked.

The invention has the advantages that:

new energy automobile when needs charge, travel to fill electric pile other, make preceding wheel press on the sign board, if preceding wheel does not press on the sign board, then the charging wire can't be followed and is filled electric pile and pull out, has played the effect of standardizing the parking, prevents that vehicle parking position distance from filling electric pile's position is far away, leads to the charging wire to excessively drag the fracture, causes the problem appearance of damage.

When new energy automobile's preceding wheel pressure was on the sign board, the sign board is sunken in the seal box under the pressure effect of vehicle, atmospheric pressure increase in the seal box, the air admission air duct is inside and promote the sliding plug and be close to drive chamber direction, then drive screw post rebound, because of the unable rotation of screw thread section of thick bamboo, then the in-process of screw post rebound takes place to rotate, drive the tooth post rotation of coaxial fixed with it, the tooth post drives the gear rotation with it, then the positive rotation of receipts wheel, emit the charging wire, then can pull out the charging wire easily outside the receipts groove, charge new energy automobile.

After the completion of charging, with charging wire and vehicle separation, the vehicle is gone and is left the sign board, the sign board is bounced and the reconversion, with the gas in the air duct in pumping to the seal box again, under the atmospheric pressure effect, the sliding plug drives screw post downstream and resets, thereby the screw post drives the reversing of tooth post and drives the back of a roll take-up pulley reversing rotation through the gear, with the automatic roll-up back of charging wire in the back of a roll take-up groove, avoid the charging wire to put at will and cause the puzzlement to staff and traffic.

During charging, the sliding plug drives the threaded column to move upwards to the limit position, the first elastic electric connecting piece is contacted with the second elastic electric connecting piece, the charging wire is conducted with an external power supply, and charging of a vehicle is achieved; after the completion of charging, the vehicle drives away from the sign board, and smooth stopper drives the screw thread post and moves down to reset, and first elasticity connects the electric piece and connects the electric piece disconnection contact with the second elasticity, and the charging wire is in the outage state, can prevent that the pedestrian from touching by mistake and lead to the dangerous problem of electric shock to take place.
