Abstract

This application belongs to the technical field of charging protection, and provides a charging protection circuit, a charging protection device and a robot. The voltage collecting circuit collects the voltage signal of the charging interface, and then adopts the main control circuit to combine the collected voltage collecting signal with the preset The charging protection threshold voltage is compared, and a voltage comparison signal is output according to the comparison result. The switch control circuit generates a control signal according to the voltage comparison signal, and the charging switch circuit controls the connection state between the charging interface and the battery according to the control signal, thereby solving the plug-in Or charging methods such as automatic recharging may have potential short circuit or electric shock because the charging port is exposed and charged.

Description

technical field [0001] The application belongs to the technical field of charging protection, and in particular relates to a charging protection circuit, a charging protection device and a robot. Background technique [0002] Large-scale service robot is a new intelligent equipment. As a large-scale intelligent equipment, the input voltage and current are also relatively large. Therefore, the charging methods of robots currently on the market are plug-in or automatic recharging. [0003] However, charging methods such as plug-in or automatic recharging have hidden dangers of short circuit and electric shock because the charging port is exposed and charged. Contents of the invention [0004] The purpose of this application is to provide a charging protection circuit, a charging protection device and a robot, aiming to solve the problem of short circuit and electric shock hazards in charging methods such as plug-in or automatic recharging because the charging port is expose...
