The invention discloses an electronic steering column lock which comprises a driving unit for providing power for an execution unit, the execution unit used for transmitting power and executing unlocking and locking actions, a control unit used for sending and receiving a working instruction and controlling the on-off of the execution unit, a fixing unit used for supporting and locking the electronic steering column lock to enable the electronic steering column lock and the steering column to be fixedly connected into a whole, and a control unit electrically connected with the execution unit and the driving unit. According to the invention, the transmission of locking and unlocking, the triggering of locking and unlocking detection and the safety function of the spring bolt can be realizedonly through a single part gear, screw rod and nut rotating structure, so that the number of parts, the material cost and the assembly cost are reduced to the greatest extent, the number of parts isreduced, the system is simplified, and the reliability is further improved.
Description
technical field [0001] The invention relates to the technical field of automobile electronics, in particular to an electronic steering column lock. Background technique [0002] Electronic steering column lock (Electronic Steering Column Lock, abbreviated as ESCL) is a part of the vehicle anti-theft system, which is used for locking and unlocking the steering wheel in the keyless entry and starting system. The locking and unlocking action of ESCL is realized by controlling the motor action in ESCL. Because it is electronic, it does not need to turn the switch to unlock and unlock the engine of the car like a mechanical lock. When the electronic steering column lock is detected After the conditions required for locking and unlocking are met, the deadbolt system can perform the corresponding locking and unlocking actions, so as to protect the safety of the car and provide users with great convenience. Its safety goal is to prevent accidental locking of the car while it is in ...
