Abstract

A transmission apparatus for a vehicle includes a shift lever in which a cover is movably disposed. The transmission apparatus, which performs a gear shift according to a gear shift command received by the shift lever, includes a bottom portion capable of moving linearly so that gear shift stages including a first gear shift stage and a plurality of second gear shift stages are mutually shifted, a body rotatably coupled to an upper side of the bottom portion so that the plurality of second gear shift stages are mutually shifted, and a cover movably disposed on an upper end of the body so that a position of the cover is varied according to the mutual shift of the gear shift stages.

First claim

What is claimed is:

1. A transmission apparatus for a vehicle, which performs a gear shift according to a gear shift command received by a shift lever, the transmission apparatus comprising:
a bottom portion configured to move in a linear direction so that gear shift stages including a first gear shift stage and a plurality of second gear shift stages are mutually shifted;
a body rotatably coupled to an upper side of the bottom portion so that the plurality of second gear shift stages are mutually shifted; and
a cover movably disposed on an upper end of the body,
wherein the body includes a first body configured to face the linear direction to input the gear shift command to the shift lever and the body includes a second body configured to face in a direction opposite to the first body, and
wherein the cover is disposed on the first body or on the second body so that a size of the cover disposed on the first body and a size of the cover disposed on the second body are configured to vary according to the mutual shift of the gear shift stages.

2. The transmission apparatus according to claim 1 , wherein the body further comprises a rail provided so that the cover is movable coupled to the body.

3. The transmission apparatus according to claim 1 , wherein the body comprises a rail provided so that the cover is movable coupled to the body.

4. The transmission apparatus according to claim 1 , wherein the cover comprises an elastic material.

5. The transmission apparatus according to claim 1 , further comprising:
a potentiometer configured to measure a rotation angle of the body so that the shift lever receives the gear shift command according to rotation of the body.

6. The transmission apparatus according to claim 5 , further comprising:
a rotary encoder integrated motor having a rotary encoder configured to receive the gear shift command according to the rotation angle of the body measured by the potentiometer and a motor configured to move the cover in response to the gear shift command received by the rotary encoder.

7. The transmission apparatus according to claim 6 , further comprising:
an accommodation portion having an accommodation space in which the bottom portion is accommodated to linearly move forward and backward.

8. The transmission apparatus according to claim 7 , further comprising:
a tact switch provided to protrude from an inside of the accommodation portion into the accommodation space toward the shift lever to receive the gear shift command by interfering with the bottom portion.

9. The transmission apparatus according to claim 1 , wherein the shift lever is configured to move forward and backward between the first gear shift stage and the plurality of second gear shift stages disposed in front of the first gear shift stage.

10. The transmission apparatus according to claim 1 , wherein the plurality of second gear shift stages are configured to be mutually shifted by rotating by 90 degrees.

11. The transmission apparatus according to claim 1 , further comprising:
an accommodation portion having an accommodation space in which the bottom portion is accommodated to linearly move forward and backward.

12. The transmission apparatus according to claim 11 , further comprising:
a tact switch provided to protrude from an inside of the accommodation portion into the accommodation space toward the shift lever to receive the gear shift command by interfering with the bottom portion.

13. The transmission apparatus according to claim 1 , wherein the first gear shift stage comprises a P-gear shift stage, and the plurality of second gear shift stages comprises a D-gear shift stage, a N-gear shift stage, and a R-gear shift stage.

14. The transmission apparatus according to claim 13 , wherein, when the shift lever receives the gear shift command corresponding to the D-gear shift stage or the R-gear shift stage, the cover is disposed on the body so that a size of the cover disposed on the first body is larger than that of the cover disposed on the second body.

15. The transmission apparatus according to claim 13 , wherein, when the shift lever receives the gear shift command corresponding to the N-gear shift stage, the cover is disposed on the body so that a size of the cover disposed on the first body and that of the cover disposed on the second body are a same size.

16. The transmission apparatus according to claim 13 , wherein the D-gear shift stage and the R-gear shift stage are spaced apart from each other by 180 degrees, and the N-gear shift stage is spaced apart from the D-gear shift stage or the R-gear shift stage by 90 degrees.

17. The transmission apparatus according to claim 13 , wherein, when the shift lever receives the gear shift command corresponding to the P-gear shift stage, the cover is disposed only on the first body.

18. A transmission apparatus for a vehicle, which performs a gear shift according to a gear shift command of a gear shift stage received by a shift lever configured to move in a linear direction, the transmission apparatus comprising:
a body having a first body configured to face the linear direction to input the gear shift command to the shift lever and having a second body configured to face in a direction opposite to the first body; and
a cover movably disposed on an upper end of the body,
wherein the cover is configured such that a size of the cover disposed on the first body and a size of the cover disposed on the second body are varied according to the gear shift command of the gear shift stage.
