This embodiment is through the flexible of lease platform control cylinder telescopic link to realize returning the car unusually with can not normally returning the car, improved reliability, convenience and the security of returning the car greatly. When the vehicle is normally returned, the normal vehicle returning pile end communication conduction interface and the vehicle returning end communication conduction interface are just opposite to signal connection, and the lock tongue of the electronic lock I extends out to be locked in the hole V. When the vehicle is abnormally returned, the communication conduction interface at the end of the abnormal vehicle returning pile and the communication conduction interface at the end of the abnormal vehicle returning pile are just opposite to the signal connection, and the lock tongue of the second electronic lock extends out to be locked in the fifth hole. The electric automobile returns the car convenient to use, and the security and the reliability of returning the car are high, and intelligent degree is high.
The embodiments of the present invention have been described above with reference to the accompanying drawings, but the implementation is not limited to the above-described embodiments, and those skilled in the art can make various changes or modifications within the scope of the appended claims.
