Description

KNOB POSITION CHANGING TYPE ELECTRONIC AUTOMATIC TRANSMISSION LEVER [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electronic type shift lever of a vehicle, and more particularly, to an electronic type shift lever of a vehicle, which includes a knob- To a shift lever.

Generally, a transmission is a device that transmits power generated by an engine to a driving wheel by changing a rotational force and a speed so as to be suitable for a driving state of the vehicle, and is classified into a manual transmission and an automatic transmission.

The driver who operates the vehicle can change the speed change stage of the manual transmission or the automatic transmission to the desired speed change stage by operating the shift lever mounted on the console surface or the handle around the driver's seat.

The manual transmission is operated in such a manner that when a driver selects a gear corresponding to the running condition of the vehicle using a shift lever, the driver transmits a desired motion to the transmission through a cable or a rod. In the automatic transmission, when the driver moves the shift lever, The driver operates the inhibitor switch to transmit the desired motion to the transmission.

In particular, in recent years, an electronic shift lever has been increasingly used instead of a mechanical shift lever, in which a mechanical connection structure between a transmission and a shift lever is replaced with an electrical connection structure through an actuator and an ECU.

Unlike the mechanical shift lever, the electronic shift lever is not provided with a mechanical cable connection structure and has a disadvantage of having a position sensor portion for converting the shift position of the driver into an electronic signal. However, it has an excellent lever operation force and operation feeling, .

The electronic type shift lever includes a lever-type electronic shift lever that operates the electronic shift lever protruded on the console surface of the vehicle as a front and a back, a cylindrical electronic shift lever mounted on the console surface of the vehicle, Type electronic shift lever, a column-type electronic shift lever that operates the electronic shift lever mounted on the handle side of the vehicle up and down, and a button-type electronic shift lever that operates the button of the shift position of the vehicle by pressing the button.

FIG. 1 is an exemplary view showing a lever-type electronic shift lever of a general vehicle, and FIG. 2 is an exemplary view showing a method of gripping a lever-type electronic shift lever of a general vehicle.

1, a general lever type electronic shift lever of a vehicle includes a rod 2 mounted on a console surface 1 of the vehicle so as to be rotatable in the front-rear direction, And a knob 3 gripped by the knob 3.

Specifically, the knob 3 is divided into a vertical knob shown in FIG. 1A, a horizontal knob shown in FIG. 1B, and a vertical knob shown in FIG. Each vehicle is unified with one concept.

However, the driver grasps the knob 3 in various ways according to his / her preference. At this time, the conventional fixed knob 3 gives a good feeling to some drivers, but inconvenience to other drivers .

For example, a driver holding a knob 3 by a side arm grip method as shown in FIG. 2A gives a good operation feeling to the vertical knob, but inconvenience to other drivers.

On the contrary, the driver of the knob 3 grasps the knob 3 by the overhand grip method as shown in FIG. 2B, but the lateral knob gives a good operation feeling, but may cause inconvenience to other drivers.

That is, in the conventional electronic type shift lever, the knob does not reflect the driver's preference and is disposed only in a fixed form according to the concept of the vehicle, which is an element that hinders the operation feeling of the electronic type shift lever.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-described problems of the conventional art, and it is an object of the present invention to provide a gearshift device capable of realizing various knob shapes with a relatively simple structure and significantly improving the operation feeling of the electronic shift lever And an object of the present invention is to provide a knob conversion type electronic shift lever.
