Referring to fig. 6 and 7, a plurality of second blocking grooves 3022 are formed in the circumferential side surface of the second bushing 302, the length direction of the second blocking grooves 3022 is identical to the length direction of the second bushing 302, and the plurality of second blocking grooves 3022 are uniformly circumferentially distributed along the axis of the second bushing 302. The second partition groove 3022 extends to the bottom end surface of the second liner 302, and is provided to open at the bottom end surface of the second liner 302. The second blocking groove 3022 is provided such that a plurality of second claws 3023 are formed on the bottom of the second bushing 302, and the second claws 3023 are held by the body 201.

When the second bushing 302 pushes the first bushing 301, the reaction force applied to the second bushing 302 pushes the plurality of second claws 3023 to approach each other, so that the plurality of second claws 3023 hug the body portion 201. The second claw 3023 is arranged to facilitate the bottom of the second bushing 302 to be elastically deformed, and to facilitate the second claw 3023 to hug the main body 201 to eliminate the gap between the second bushing 302 and the shift pin 2.

Optionally, a gap is left between the circumferential side of the second bushing 302 and the inner wall of the shift lever 1.

Referring to fig. 3, a gap is left between the circumferential side surface of the second bushing 302 and the inner wall of the shift lever 1, thereby reducing the contact area of the bushing assembly 3 and the inner wall of the shift lever 1. The second bushing 302 is less likely to rub against the inner wall of the shift lever 1, reducing the possibility of rattling inside the shift lever 1.

Optionally, the elastic element 4 is sleeved on the stop pin 2.

Referring to fig. 3, the elastic member 4 includes a spring, and the spring is sleeved on the stop pin 2. Both ends of the spring abut against the inner end surface of the shift lever 1 and the top surface of the second bushing 302, respectively.

Due to the arrangement, the elastic piece 4 is sleeved on the stop pin 2, so that the axis of the elastic piece 4 is not easy to change and deflect, and the pressure is conveniently applied to the bushing assembly 3.

The following is an introduction of the internal structure of the electronic shift pin 2:

an assembly gap is left between the shift lever 1 and the shift pin 2 so that the shift pin 2 is assembled into the shift lever 1. The bushing assembly 3 eliminates the gap between the shift lever 1 and the shift pin 2, so that the shift lever 1 is not easily loosened when operated.

The first bushing 301 is sleeved on the connecting portion 202, and a hole wall of the first tapered hole 3011 of the first bushing 301 is matched with the tapered surface 2021 of the connecting portion 202, when the first bushing 301 is pressed down, the hole wall of the first tapered hole 3011 is tightly held on the tapered surface 2021, so that a gap between the first bushing 301 and the shift pin 2 is eliminated, and a side wall of the first bushing 301 is expanded outward under a reaction force of the tapered surface 2021, so that an outer side wall of the first bushing 301 abuts against an inner wall of the shift lever 1, and the gap between the first bushing 301 and the shift lever 1 is eliminated.

The elastic element 4 is applied to the second bushing 302 to be away from the second bushing 302, the second bushing 302 presses the first bushing 301 downwards, the second bushing 302 abuts against the hole wall of the second taper hole 3012 of the first bushing 301, and when the second bushing 302 presses the first bushing 301 downwards, the vertical component of the pressure received by the first bushing 301 drives the first bushing 301 to press downwards. At the same time, the second bushing 302 is subjected to a reaction force from the first bushing 301, so that the bottom end of the second bushing 302 retracts to hug the main body 201, thus eliminating the gap between the second bushing 302 and the gear pin 2.

The shift pin 2 is supported by the first bushing 301 and the second bushing 302, so that the assembly of the shift pin 2 is more stable, only the first bushing 301 is in contact with the shift lever 1, the gap between the bushing assembly 3 and the shift pin 2 is eliminated, the contact area between the bushing assembly 3 and the shift lever 1 is reduced, the friction between the bushing assembly 3 and the shift lever 1 is reduced, and the possibility of abnormal noise is reduced. At the same time, the amount of material required for the liner assembly 3 is reduced, resulting in cost savings.

Another embodiment of the present application provides an automobile comprising the electronic shifter as described above.
