Abstract

The invention discloses a safeguard device for a charging port of an electric automobile charging pile. The safeguard device comprises a shell, a step motor, a bin gate, a gear, a rack, guide sheets, infrared reflective proximity switch sensors, Hall sensors, magnets and a singlechip control circuit; the shell and the guide sheets are fixed on the inner wall of the charging pile, the shell is provided with a straight opening matched with the guide sheets to form a guide mechanism, and the bin gate is arranged in the guide mechanism; the gear is arranged on a shaft of the step motor, and the rack matched with the gear is arranged on the bin gate; the two infrared reflective proximity switch sensors are arranged on the inner wall of the charging pile and used for detecting complete opening and complete closure of the bin gate respectively; the magnets are arranged at the edge of the outer end face of the gear, and the Hall sensors are arranged at the corresponding positions; and the infrared reflective proximity switch sensors, the Hall sensors and the step motor are connected with corresponding ports of the singlechip control circuit respectively. The safeguard device is safe, reliable, low in energy consumption, simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to a safety protection device for a charging port of a charging pile of an electric vehicle. Background technique [0002] At present, electric vehicles have attracted much attention as new energy vehicles, and at the same time, charging piles for charging equipment for electric vehicles have an increasing impact on daily life. There are two common types of door switches or safety protection devices for the charging port of electric vehicle charging piles: one is a purely manual mechanical door switch; the other is an electromechanical door switch that realizes the door opening and closing function through an electromagnet. The purely manual mechanical switch door is complicated to operate and is not easy to use. The device in the form of an electromagnet attracts the charging port door or lock tongue through magnetic force to realize the switching function of the...
