The invention discloses an automobile electric power steering device. The automobile electric power steering device consists of a lock body, a driving part assembly, a lock rod, a printed circuit board and a locking / unlocking sensing part, wherein one side of the lock body is open, and is provided with a lock hole; the printed circuit board and the driving part assembly are arranged in the lock body, and the lock rod is driven by the driving part assembly to move in a reciprocating way in the lock hole; the locking / unlocking sensing part is arranged on the edge of the printed circuit board, is in contact with a part of the locking / unlocking sensing part, and is used for sensing the steering column locking position and the steering column unlocking position of a locking rod according to the contact position change of the driving part assembly. By applying the automobile electric power steering device disclosed by the invention, the influence of a surrounding magnetic field on an electronic component is avoided from the source, the practical locking and unlocking states of a steering column can be sensed without any error through a physical measure for over 30, 000 times, the durability and reliability of a product are enhanced, and the assembly time is greatly shortened.
Description
technical field [0001] The invention relates to an automobile electric power steering device, in particular to an automobile electric power steering device which can accurately identify the locking and unlocking states of a steering column and improve product durability. Background technique [0002] In general, various anti-theft systems are installed on the car to prevent theft. By taking preventive measures in advance, the third party who is not allowed can not operate the steering wheel for driving, so as to prevent the electric car from being stolen. The power steering device is one of the more representative examples. [0003] Korean "Patent Publication" No. 10-2013-0038693 is an electric power steering device for automobiles published by one of the applicants. Inside the lock body, there is a driving part assembly with a movable lock bar, and it can be driven Driven by the internal assembly, it moves through the lock hole, and engages or disengages with the lock groo...
