It is a figure which shows the state schematically.

A column type shift lever device according to an exemplary embodiment of the present invention is mounted on a steering column of a vehicle and is configured to select and operate a shift range by a user, and generates a signal for a selected shift range to generate an external device such as a vehicle controller. Is configured to transmit a signal to. The shift lever device includes a lever shaft 100, an auto knob unit 200, and an auto detection sensor module 300.

The lever shaft 100 is rotatably coupled to the body housing 10 coupled to the steering column (not shown) in a vertical direction and has a HAZARD function or power as the lever shaft 100 is rotated in the vertical direction. (POWER) function can be configured to be performed selectively.

The auto knob unit 200 is coupled to one end of the lever shaft 100 so as to select and operate the shift range, and the auto sensing sensor module 300 adjusts the shift range selected by the rotational movement of the auto knob unit 200. It is coupled to one side of the lever shaft 100 to sense and generate a signal.

At this time, the knob module 220 is configured to be able to rotate in the front-rear direction in a state in which the linear movement in a horizontal direction in the left and right direction along the longitudinal direction of the lever shaft 100 in the reference position.

That is, when the knob module 220 is in the left and right intermediate positions of the reference position, the knob module 220 is rotationally restrained, and the knob module 220 is left or right along the longitudinal direction of the lever shaft 100 from the reference position. It is comprised so that rotation operation is possible only in the state which moved linearly in the direction. At this time, the shift range is selected by the rotation operation of the knob module 220.

Therefore, in order to change the shift range, the knob module 220 must first be linearly moved in the left and right direction, and then rotated. Therefore, the shift operation is inadvertently inadvertently inadvertently provided by the driver, thereby providing a safer driving condition.

The knob module 220 is elastically supported to return to the reference position from the left and right directions by a separate elastic spring 230 as shown in FIG. That is, elastic springs 230 are provided on the left and right sides of the knob module 220 to elastically support the knob module 220 in the left and right directions so that the knob module 220 is positioned at the reference position (see FIGS. 5 and 6). . Therefore, after the knob module 220 is moved left and right along the longitudinal direction of the lever shaft 100 by the user's operation, when the user's operating force is released, the knob module 220 is referred to the elastic spring 230 again. It will return to the position. Meanwhile, a separate stopper part 213 may be formed on the left and right sides to limit the left and right movement range of the knob module 220 inside the auto tow case 210.

Thus, the knob module 220 can freely move in a left and right direction. However, when the knob module 220 is in the reference position, the guide protrusion 222a is engaged with the guide groove 311 so as to be rotationally constrained, so that the knob module 220 is rotationally constrained and moves linearly to the left. In this case, since the guide protrusion 222a is disengaged from the guide groove 311 with respect to the forward rotational movement, the knob module 220 may rotate forward. Similarly, even when the knob module 220 moves linearly in the right direction, the guide module 222a is disengaged from the guide groove 311 with respect to the backward rotation movement, so that the knob module 220 can rotate backward.

Meanwhile, the knob module 220 may further include a detent block 223 coupled to the knob dial 221 to linearly move and rotate in a straight line with the knob dial 221. At this time, the first detent protrusion 250 is mounted on the lever shaft 100 to protrude along the radial direction, and the detent block 223 has a first detent to generate a feeling of operation for the rotational movement of the knob module 220.

In addition, a separate slide holder 260 may be mounted on the lever shaft 100 to guide the protruding direction of the first detent protrusion 250 and to stably protrude the first detent protrusion 250.

According to this structure, when the knob module 220 rotates, the first detent protrusion 250 protruding from the lever shaft 100 is inserted into the first detent groove 223a of the detent block 223. Meshing and rotational operation feeling occurs. At this time, the rotational operation feeling may be configured to occur in a manner that is stopped according to the shift range.

On the other hand, the auto sensor module 300 is integral with the magnet holder 310 and the magnet holder 310 coupled to the lever shaft 100 to move in rotation with the moving block rod 222 of the knob module 220.
