Abstract

Disposed is an organ type electronic shift lever formed on a console surface at a periphery of a driver seat in a vehicle. The electronic shift lever may include a step motor coupled to the console surface and having both ends to which motor rotation shafts are connected, a pair of lever arms each having one end rotatably coupled to one or each of the motor rotation shafts, a pair of lever pins each rotatably coupled to the other end of one or each of the lever arms, a shift lever having side portions rotatably connected to the lever arms by the lever pins and a rear end to which a magnetic unit is coupled, a display unit formed on the shift lever, and a recognition sensor formed in the console surface and sensing a position of the magnetic unit. When the shift lever is moved forward or rearward while forming an inclination angle with the console surface, a gear shift stage of the vehicle is changed.

First claim

What is claimed is:

1. An organ type electronic shift lever which is formed on a console surface disposed at a periphery of a driver seat in a vehicle, the electronic shift lever comprising:
a step motor which is coupled to the console surface and has both ends to which motor rotation shafts are connected;
a pair of lever arms each of which has one end coupled to one or each of the motor rotation shafts so that the pair of lever arms is rotatable about the motor rotation shafts;
a pair of lever pins each of which is rotatably coupled to the other end of one or each of the lever arms;
a shift lever which has side portions rotatably connected to the lever arms by the lever pins, and a rear end to which a magnetic unit is coupled;
a display unit which is formed on one surface of the shift lever; and
a recognition sensor which is formed in the console surface in a longitudinal direction thereof, and senses a position of the magnetic unit,
wherein when the shift lever is moved forward or rearward while forming an inclination angle with respect to the console surface, a gear shift stage of the vehicle is changed.

2. The organ type electronic shift lever of claim 1 , wherein the inclination angle formed between the shift lever and the console surface includes:
a P-stage inclination angle which is an inclination angle formed between the shift lever and the console surface when the gear shift stage of the vehicle is a P-stage;
an R-stage inclination angle which is an inclination angle formed between the shift lever and the console surface when the gear shift stage of the vehicle is an R-stage;
an N-stage inclination angle which is an inclination angle formed between the shift lever and the console surface when the gear shift stage of the vehicle is an N-stage; and
a D-stage inclination angle which is an inclination angle formed between the shift lever and the console surface when the gear shift stage of the vehicle is a D-stage,
wherein the R-stage inclination angle is smaller than the P-stage inclination angle, the N-stage inclination angle is smaller than the R-stage inclination angle, and the D-stage inclination angle is smaller than the N-stage inclination angle.

3. The organ type electronic shift lever of claim 2 , wherein when an engine of the vehicle is started, the shift lever is moved forward by rotation of the motor rotation shafts connected to the step motor while forming the P-stage inclination angle with respect to the console surface.

4. The organ type electronic shift lever of claim 2 , further comprising:
an engine off stage inclination angle when the shift lever is moved rearward by a predetermined length and disposed in parallel with the console surface,
wherein when the shift lever maintains the engine off stage inclination angle with respect to the console surface for a predetermined time, the engine of the vehicle is turned off.

5. The organ type electronic shift lever of claim 4 , wherein when the inclination angle is changed to the engine off stage inclination angle in a state in which the shift lever forms the P-stage inclination angle or the N-stage inclination angle with respect to the console surface, and the engine off stage inclination angle is maintained for the predetermined time, the engine of the vehicle is turned off, and when the inclination angle is changed to the engine off stage inclination angle in a state in which the shift lever forms the R-stage inclination angle or the D-stage inclination angle with respect to the console surface, the inclination angle returns back to the R-stage inclination angle or the D-stage inclination angle, respectively.

6. The organ type electronic shift lever of claim 1 , wherein a distance from the lever pin to the rear end of the shift lever is longer than a distance from the lever pin to a front end of the shift lever.

7. The organ type electronic shift lever of claim 1 , wherein the step motor includes:
a rotor which is disposed at a center of the step motor, connected with the motor rotation shafts, and formed of a permanent magnet; and
a stator which is disposed outside the rotor, and has a plurality of protruded portions that protrudes in a direction toward the center of the step motor, and
when the shift lever is moved and the motor rotation shafts are rotated, a distance between the rotor and the stator is varied, such that cogging torque is generated, and feeling of moderation is created.

8. The organ type electronic shift lever of claim 7 , wherein the protruded portions are formed to have different heights from each other so that the generated cogging torque is different and in accord with the gear shift stage of the vehicle.

9. The organ type electronic shift lever of claim 1 , further comprising:
rollers which are rotatably coupled to both sides of the rear end of the shift lever; and
guides which are formed on the console surface in the longitudinal direction thereof and slidably accommodates the rollers.
