The plurality of fixing grooves 240 may be formed in a manner The unit 400 can be used to limit the rotation of the denest groove 200, and a detailed description thereof will be described later.

In the embodiment of the present invention, the plurality of dentent grooves 220 and the plurality of fixing grooves 240 are formed on different members, respectively, and then combined to form the groove groove 200. However, However, the present invention is not limited thereto, and the plurality of dentent grooves 220 and the plurality of fixing grooves 240 may be integrally formed.

The driving unit 300 may include an actuator 310 and a plurality of gear units 320 and 330 and 340. The driving force generated from the actuator 310 may be transmitted through the plurality of gear units 320, The knob 100 may transmit the rotational force generated when the knob 100 is rotated by the external force to the tooth groove 200.

Hereinafter, in the embodiment of the present invention, the plurality of gear units 320, 330, and 340 will be referred to as a first gear unit 320, a second gear unit 330, and a third gear unit 340, respectively.

2 to 7, the first gear unit 320 may be connected to the actuator 310 and rotated when the actuator 310 is driven. For example, the first gear unit 320 may include a worm wheel engaged with a worm gear 311 provided on a rotary shaft of the actuator 310, and may be rotated when the actuator 310 is driven.

The first gear unit 320 may be rotated when the actuator 310 is driven to transmit the rotational force of the actuator 310 to the second gear unit 330.

The second gear unit 330 may be rotatably mounted on one surface of the first gear unit 320 and the second gear unit 330 may include an insertion protrusion 321 formed on one surface of the first gear unit 320, The hollow 330a may be formed.

Since the central axis A2 of the insertion protrusion 321 is spaced apart from the rotation axis A1 of the first gear unit 320 in one direction, The first gear unit 330 can revolve about the axis of rotation A1 of the first gear unit 320. [

The knob 100, the first gear unit 320 and the third gear unit 340 rotate about the same axis as the rotation axis A1 of the first gear unit 320 in the embodiment of the present invention An example will be described.

The third gear unit 340 is inserted into the insertion groove 250 formed on the other surface of the tooth groove 200, that is, the surface opposite to the surface on which the knob 100 is mounted, and the first internal gear 341a And has a hollow 342a into which the shaft 110 of the knob 100 having passed through the hollow 210 of the tooth groove 200 is inserted from the insertion member 341 and the insertion member 341 formed in one direction, And may include an elongate member 342.

Since the shaft 110 of the knob 100 is inserted into the extension member 342 of the third gear unit 340, the rotational force generated when the knob 100 is rotated is transmitted to the third gear unit 340 The rotational force of the third gear unit 340 can be transmitted to the knob 100. In this case,

The extension member 342 can be connected to the sensing unit 500 that senses the speed change stage through the hollow 330a of the second gear unit 330 and the hollow 320a of the first gear unit 320, A detailed description of the unit 500 will be described later.

The second gear unit 330 has a larger diameter than the first external gear 331 and the first internal gear 341a that are engaged with the first internal gear 341a of the insertion member 341, And a second external gear 332 engaged with a second internal gear 260 formed on an outer peripheral surface of the second internal gear 260. [

Accordingly, the rotational force transmitted from the knob 100 to the third gear unit 340 is transmitted to the second gear unit 330 through the first external gear 331 and is transmitted to the second gear unit 330 by the second external gear 332, The knob 100 can be transmitted to the groove 200. When the knob 100 is rotated by the driver, the groove groove 200 is rotated together with the knob 100 to generate an operation feeling.

Since the center axis A2 of the second gear unit 330 is revolved around the axis of rotation A1 of the first gear unit 320 in the embodiment of the present invention, The diameters of the two external gears 332 are smaller than the first internal gear 341a and the second internal gear 260 and only a part of the outer ends thereof are engaged with each other. When the actuator 310 is driven, (330) rotates together with revolution.

In this way, the center axis A2 of the second gear unit 330 is spaced apart from the rotation axis A1 of the first gear unit 320 in one direction to obtain a deceleration effect. In order to obtain a high gear ratio, As compared with the case of using a gear having a large difference in diameter.

Meanwhile, in the embodiment of the present invention, the actuator 310 of the drive unit 300 functions to return the knob 100 to the main cut-off when the returning condition to the main cut-off is satisfied.

For example, the actuator 310 is operated when the driver turns off the vehicle in the D-stage state or when a separate operation is input from the driver, thereby rotating the knob 100 to automatically return to the main block I will.

Here, in the embodiment of the present invention, the case where the non-stop is a R range, a N range and a D range in which the vehicle is capable of running, and the main breaking is a P range as a speed change stage in which the vehicle is restricted in running .

In the embodiment of the present invention, the case where the drive unit 300 returns the knob 100 to the main break when the return condition from the non-stop to the main break is satisfied is described as an example. However, The control unit 300 may return the knob 100 to a predetermined speed change stage according to various return conditions.

For example, the drive unit 300 may serve to return the knob 100 to the previous speed change stage when a wrong operation of the knob 100 occurs in the running state of the vehicle. More specifically, when the knob 100 is rotated by the erroneous operation of the driver so that the selection of another gear position can be prevented from being selected during traveling of the vehicle in the D-stage state, It can play a role of returning to the single-stage D-stage.

In this case, when the position of the tooth groove 200 formed with the second internal gear 260 engaged with the second external gear 332 is not fixed, the tooth groove 200 is also rotated together with the lock unit 400 Serves to limit the rotation of the tooth groove 200 during the step of returning from the speed change stage by the actuator 310. [

8 and 9 are side views illustrating a locking unit according to an embodiment of the present invention.

8 and 9, the lock unit 400 may include a lock rod 420 whose position is changed by the actuator 410 and the actuator 410. [

The actuator 410 may be a solenoid and may include a moving rod 411 moving linearly and the locking rod 420 may be connected to one end of the moving rod 411 to move the moving rod 420 One end of the lock rod 420 is inserted into any one of the plurality of the fixing grooves 240 to be rotated about the rotation axis 420a to restrict the rotation of the groove groove 200. [

At this time, a connecting groove 411a is formed at one end of the moving rod 411 and a connecting protrusion 421 formed in the locking rod 420 is inserted into the connecting groove 411a. As the moving rod 411 moves, The connection protrusion 421 flows inside the connection groove 411a so that the linear movement of the movable rod 411 can be converted into the rotational movement of the lock rod 420. [

That is, when the rotation of the tooth groove 200 is to be restricted, the lock unit 400 inserts one end of the lock rod 420 into any one of the plurality of fixing grooves 240 as shown in FIG. 8, 8, the lock rod 420 is rotated in the opposite direction so that one end of the lock rod 420 is detached from the plurality of lock grooves 240 as shown in FIG. 9, .

In the embodiment of the present invention, the actuator 410 of the lock unit 400 is constituted by a solenoid. However, the present invention is not limited thereto, and the lock rod 420 may be rotated around the rotation axis 420a Various types of actuators can be used.

Meanwhile, in the embodiment of the present invention, the case where the lock unit 400 restricts the rotation of the tooth groove 200 when the knob 100 is returned to the main cut by the drive unit 300 is described, for example, The lock unit 400 may implement a shift lock function when the speed change stage is changed by the rotation of the knob 100. [

For example, in the case of changing from the P-stage to the R-stage, the lock unit 400 restricts the rotation of the tooth groove 200, releases the lock when the brake pedal is operated so that the knob 100 is rotated You can do it.

When the actuator 310 of the drive unit 300 is not driven so that the first gear unit 320 is rotated in a direction opposite to the direction of rotation of the knob 100, The rotational force of the knob 100 is transmitted to the third gear unit 340, the second gear unit 330 and the stationary groove 200 when the knob 100 rotates so that the stationary groove 200 The operation feeling may be generated.

The actuator 310 of the drive unit 300 is driven and the driving force of the actuator 310 is transmitted to the first gear unit 320 and the second gear unit 320. [ The rotation of the knob 100 may be restricted by the lock unit 400. In this case, the rotation of the knob 100 may be restricted by the lock unit 400. In this case,

This is advantageous in terms of enabling the driver to easily recognize the selection of the speed change stage by providing a sense of operation to the driver when the speed change stage is selected by the rotation of the knob 100 by the driver, In the case of returning to the set speed range, most of the driver is off the vehicle or does not actually operate the vehicle, so that unnecessary operation feeling is generated to prevent noise from being generated.

Referring again to FIGS. 2 to 4, a sensing unit 500 may be positioned at one side of the extension member 342 to sense the speed change stage selected by the rotation of the knob 100.

The sensing unit 500 includes a first gear 510 connected to the extension member 342 and a second sensing gear 520 having a magnet 521 and engaged with the first gear 510, And a sensor 530 for detecting magnetic force change.
