In addition, whether the electric vehicle exists in the current position is determined based on the judgment whether the current charging socket 4 is connected with a charging plug, so that the lateral shielding mechanism 2 and the top shielding mechanism 3a which need to be started can be accurately determined, and the integral safety protection system can be ensured to be automatically and accurately opened and closed; specifically, referring to fig. 12, if no electric vehicle is detected at d/e, two top shielding mechanisms 3a and two ii are correspondingly started; and if the d/e detects the electric vehicle, the starting position of the lateral shielding mechanism 2 and the starting number of the top shielding mechanisms 3a are determined again.
Further, a switch 6 is installed at one side of the charging socket 4, and the switch 6 is connected between the pressure sensor 5 and the processor 13. The purpose of setting up switch 6 is when no electric motor car charges, based on manually operation disconnect switch 6, makes socket 4, pressure sensor 5 all be in the outage state of charging from this, further guarantees the security of outer electric structure that leaks, avoids appearing the electric leakage problem.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
