Automatic transmission lever assembly having shift-lock cam using electromagnet

Abstract

Disclosed therein is an automatic transmission lever assembly having a shift-lock cam having an electromagnet. The automatic transmission lever assembly includes: a base bracket fixed to a frame of a vehicle; a rod; a rotating member joined to a lower end of the rod, the rotating member rotating on a predetermined shaft according to a movement of the rod for changing a transmission mode and having a locking portion formed at a position corresponding to a shift-lock; a shift-lock cam having a permanent magnet, the shift-lock cam being caught to the locking portion at a shift-lock position and being rotatable on the shaft; and an electromagnet provided at a position facing the permanent magnet, wherein when a brake signal is transferred, electric current flows to the electromagnet, so that the shift-lock cam is operated in a direction to be released from the locking portion.

What is claimed is: 
     
         1 . An automatic transmission lever assembly comprising:
 a base bracket;   a rod;   a knob button provided to an end portion of the rod;   a detent pin being vertically movable according to operation of the knob button;   a shift-lock cam making the detent pin being caught at a shift-lock position so as to prevent the knob button from being pressed, the shift-lock cam having a permanent magnet; and   an electromagnet provided at a position facing the permanent magnet,   wherein when a brake signal is transferred, electric current flows to the electromagnet, so that the shift-lock cam is operated in a direction to be released from the locking portion.   
     
     
         2 . The automatic transmission lever assembly according to  claim 1 , wherein when a brake signal is stopped, the permanent magnet of the shift-lock cam gets in contact with the electromagnet so as to be caught to the locking portion.
