Abstract
The invention discloses an electric door lock for electric vehicles with both weak-current starting and mechanical starting functions, comprising a mechanical lock body part and an MCU electronic control part. The mechanical lock body part comprises a lock shell, a lock core, a lock core sleeve, an electromagnetic controller, a knob switch, a micro switch and an ignition switch. The ignition switch has physical connection contacts and non-physical connection contacts for realizing power-on and power-off control. The MCU electronic control part comprises an MCU chip for signal reception and processing, an electronic switch and an LED indicator element. The MCU chip is electrically connected to the electronic switch and the electronic switch realizes control of the non-physical connection contacts of the ignition switch. The invention develops a new type of electric door lock, which has both weak-current starting and mechanical starting functions and meets the needs of actual use. The electric door lock realizes weak-current starting as the main unlocking method by controlling the electronic switch, which can prolong the service life of the electric door lock, while ensuring safety during use and being more convenient to use.
