[0028] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification.

[0029] Please refer to Figures 1 to 5 . It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the limited conditions for the implementation of the present utility model. Therefore, they do not have technical essential significance. Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the effects that the present utility model can produce and the purposes that can be achieved, should still fall within the scope that can be covered by the technical content disclosed in the present utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle", and "one" cited in this specification are only for the convenience of clear description and are not used to limit the scope for the implementation of the present utility model. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope that the present utility model can implement.

[0030] In order to be able to describe the present utility model in detail, a shift mechanism and a vehicle of the present utility model will be specifically described next:

[0031] Please combine with Figures 1 to 5As shown in the figure, the present utility model provides a shifting mechanism, which includes a shifting handle 1 and a shifting rod 2. A connecting hole is provided inside the shifting handle 1; the shifting rod 2 is snap-connected to the shifting handle 1 and at least partially sleeved inside the connecting hole. Inside the connecting hole, there is an assembly gap between the shifting handle 1 and the shifting rod 2 along the radial direction of the shifting rod 2; wherein, a filling structure is arranged in the assembly gap, and the filling structure is used to fill the assembly gap. By arranging the filling structure in the assembly gap, when the operator manipulates the shifting mechanism to shift gears through the shifting handle 1, the shifting rod 2 can be prevented from shaking inside the connecting hole, generating abnormal noises, which affects the operation experience of the operator. At the same time, the shaking of the shifting rod 2 inside the connecting hole will affect the connection between the shifting rod 2 and the shifting handle 1, resulting in the connection failure between the shifting handle 1 and the shifting rod 2. The structure of the shifting mechanism is simple, easy to produce and manufacture, and has good industrial promotion value.

[0032] As Figure 1 , Figure 4 and Figure 5 shown in the figure, wherein, the filling structure includes an elastic member arranged in the assembly gap, and the elastic member at least partially surrounds the shifting rod 2 along the circumferential direction of the shifting rod 2. By arranging the elastic member, while filling the assembly gap, when the shifting rod 2 shakes inside the connecting hole, the elasticity of the elastic member itself can be utilized to buffer the collision between the shifting rod 2 and the shifting handle 1, thereby reducing the abnormal noise between the shifting rod 2 and the shifting handle 1.

[0033] Among them, the elastic member is a rubber ring 4, and the rubber ring 4 is sleeved on the shifting rod 2. The rubber ring 4 has the advantages of low cost, simple assembly, good elasticity, etc. In some embodiments, the elastic member can be an elastic strap. The type of the elastic member can be adjusted according to actual usage needs.

[0034] Specifically, at least two rubber rings 4 are sequentially sleeved on the shifting rod 2 at intervals along the axial direction of the shifting rod 2. By arranging at least two rubber rings 4 on the shifting rod 2, the buffering effect on the connection between the shifting rod 2 and the shifting handle 1 can be enhanced, thereby reducing the abnormal noise when the shifting rod 2 and the shifting handle 1 shake, and improving the operation experience of the operator.

[0035] In detail, the filling structure further includes a limiting groove opened on the shifting rod 2 along the axial direction of the shifting rod 2. The limiting groove corresponds to the rubber ring 4, and at least part of the rubber ring 4 is accommodated in the limiting groove. By arranging the limiting groove, the rubber ring 4 can be limited in the axial direction of the shifting rod 2, preventing the rubber ring 4 from slipping axially along the shifting rod 2 and slipping out of the assembly gap. The limiting groove has a simple structure and good limiting effect on the rubber ring 4.

[0036] As Figures 1 to 3As shown in the figure, an opening end of a shift lever handle 1 is provided with a connection part 102 for connecting with a shift lever 2, and the shift lever handle 1 is connected to the shift lever 2 through the connection part 102. By providing the connection part 102, it is convenient to be clamped with the shift lever 2 through the connection part 102.

[0037] Specifically, the shift lever 2 is provided with an annular groove 202 around the axial direction of the shift lever 2, and the connection part 102 is provided with a clamping interface 101 corresponding to the annular groove. By providing a clamping member at the annular groove 202 and the clamping interface 101, the shift lever handle 1 is connected to the shift lever 2. The clamping member connects the shift lever handle 1 and the shift lever 2 through the annular groove 202 and the clamping interface 101, with a simple structure and easy production and assembly.

[0038] In this embodiment, two clamping interfaces 101 are provided on the connection part 102, and the two clamping interfaces 101 are arranged oppositely. The clamping member is a snap ring 3. The snap ring 3 includes a first clamping arm, a second clamping arm and a connecting arm connecting the first clamping arm and the second clamping arm. The first clamping arm and the second clamping arm are respectively clamped with the annular groove 202 through the two clamping interfaces 101. By clamping the shift lever handle 1 and the shift lever 2 with the snap ring 3, the assembly effect is good and it is easy to assemble. At the same time, the snap ring 3 has the advantages of simple structure, convenient installation, large elastic deformation range and large restoring force. In some embodiments, the shift lever 2 and the shift lever handle 1 are connected by an adhesive. The connection method between the shift lever 2 and the shift lever handle 1 can be adjusted according to actual use requirements.

[0039] Among them, the filling structure further includes a flat part 201 at the end of the shift lever 2 and a limiting groove with a connection hole matching the flat part 201. The limiting groove is used to accommodate the flat part 201 and limit the shift lever 2 in the circumferential direction of the shift lever 2. The above structure is simple, with good limiting effect and convenient manufacturing and processing.

[0040] The present utility model further provides a vehicle, including the shift mechanism as described above.

[0041] In summary, by providing a filling structure in the assembly gap, when an operator manipulates the shift mechanism to shift gears through the shift lever handle 1, it can be avoided that the shift lever 2 shakes in the connection hole, generating abnormal noises and affecting the operation experience of the operator. At the same time, the shaking of the shift lever 2 in the connection hole will affect the connection between the shift lever 2 and the shift lever handle 1, resulting in the connection failure between the shift lever handle 1 and the shift lever 2. The structure of the shift mechanism is simple, easy to produce and manufacture, and has good industrial promotion value.

[0042] The above embodiments are only illustrative of the principles and effects of the present utility model and are not intended to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
