An ACC door lock switch circuit that supports remote control

Abstract

This utility model relates to an electronic lock, and more particularly to an ACC ignition lock switch circuit supporting remote control, comprising: a power supply and control signal input terminal for inputting ACC power and ignition lock switch control signals; an ACC control and detection circuit connected to the power supply and control signal input terminal for controlling the opening and closing of the ACC ignition lock and detecting the switch status; and an ACC power output terminal connected to the ACC control and detection circuit for receiving power after the ACC ignition lock is opened and outputting the power to the electrical components inside the electric vehicle. This switch circuit controls the opening and closing of the ACC ignition lock by controlling the cutoff and conduction of a field-effect transistor (FET). The FET Q1 is in the cutoff state by default, and the base of the transistor Q3 is in the low-level state by default. By outputting a high-level state to the base of transistor Q3, the FET Q1 is switched from the cutoff state to the conduction state, thereby opening the ACC ignition lock, improving its service life and reliability.
