Unique motor type motor driven column apparatus

摘要

A unique motor type motor driven column apparatus may include a motor attached to a telescoping tube that slidably receives a column tube therein, wherein the telescoping tube may be pivotally coupled with a vehicle body by a tilt bracket, an actuating rod rotating by the motor, a tilt mechanism including a tilt clutch receiving the actuating rod therethrough and selectively engaged therebetween by a motor controller such that a rotation force of the actuating rod may be converted into a linear movement of the tilt mechanism to make a tilt motion of the column tube, and a telescoping mechanism including a telescoping clutch receiving the actuating rod therethrough and selectively engaged therebetween by the motor controller such that a rotation force of the actuating rod may be converted into a linear movement of the telescoping mechanism so as to make a telescoping motion of the column tube.

1. A unique motor type motor driven column apparatus, comprising:
a motor which is mounted in a column tube, wherein the column tube is joined with a mounting bracket mounted to a vehicle body and covers a steering shaft controlled by a unified motor engine control unit (“ECU”); an actuating rod supported at one or more positions by the column tube, and rotatable by the motor; a tilt mechanism including a tilt clutch converting a rotation force of the actuating rod into a linear movement force for a tilt motion by control of the unified motor ECU; a telescoping mechanism including a telescoping clutch converting a rotation force of the actuating rod into a linear movement force for a telescoping motion by control of the unified motor ECU; and tilt and telescoping sensors sensing the tilt motion of the tilt mechanism and the telescoping motion of the telescoping mechanism and transmitting electric signals to the unified motor ECU; wherein the telescoping mechanism is positioned inside the tilt mechanism; wherein the tilt mechanism further includes a first moving block and a first block housing accommodating the first moving block through which the actuating rod passes, and the tilt clutch includes a first plug rod which is selectively drawn into a first opening formed in the first block housing to lock the first moving block so that the first moving block moves linearly or drawn from the first opening to release the locked state of the first moving block so that the first moving block rotates idly; and wherein the telescoping mechanism further includes a second moving block and a second block housing accommodating the second moving block through which the actuating rod passes, the telescoping clutch includes a second plug rod which is selectively drawn into a second opening formed in the second block housing to lock the second moving block so that the second moving block moves linearly or drawn from the second opening to release the locked state of the second moving block so that the second moving block rotates idly.
