It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, unless otherwise specified, the use of directional words such as "up and down" generally means "up and down" in a state where the shift operating mechanism 100 is mounted on the vehicle, and the direction of "up and down" when the vehicle is normally running. The X direction of the vehicle refers to the length direction of the vehicle, and the Y direction of the vehicle refers to the width direction of the vehicle, and specifically, reference may be made to the X direction and the Y direction in fig. 1. The terms "inside and outside" refer to the inside and outside of the profile of the relevant component. In addition, the terms "first", "second", and the like used in the embodiments of the present disclosure are for distinguishing one element from another, and have no order or importance.

In the present disclosure, the shift operation when the shift lever 10 is rotated about the X direction of the vehicle is simply referred to as shift lever 10 lateral shifting, and the shift operation when the shift lever 10 is rotated about the Y direction of the vehicle is simply referred to as shift lever 10 longitudinal shifting. The X direction of the vehicle is simply referred to as the X direction, and the Y direction of the vehicle is simply referred to as the Y direction.

To simplify the structure of the shift operating mechanism 100 and reduce the space it occupies, a shift operating mechanism 100 is provided in the present disclosure, as shown in fig. 1-7. The shift operating mechanism 100 includes a shift lever 10, a rotary shaft member 20 and a base assembly 30. The rotating shaft member 20 is disposed on the base assembly 30, and the rotating shaft member 20 penetrates through the shift lever 10. The shift lever 10 is rotatably disposed to the base assembly 30 about the first axis 81 relative to the rotational shaft member 20, i.e., the shift lever 10 rotates relative to the rotational shaft member 20. The central axis of the rotating shaft member 20 is a second axis 82, and the shift lever 10 is rotatably disposed on the base assembly 30 around the second axis 82. One of the first axis 81 and the second axis 82 extends in the X direction of the vehicle, and the other extends in the Y direction of the vehicle, and the first axis 81 and the second axis 82 intersect.

For convenience of explanation, the following description will be given taking as an example that the first axis 81 extends in the X direction of the vehicle and the second axis 82 extends in the Y direction of the vehicle. It will be appreciated that in other embodiments, the first axis 81 may extend in the Y direction of the vehicle and the second axis 82 may extend in the X direction of the vehicle.

Through the technical scheme in the present disclosure, when lateral shifting is required, as shown in fig. 6, the shift lever 10 rotates around the X direction of the vehicle relative to the rotating shaft member 20, and when longitudinal shifting is required, as shown in fig. 7, the shift lever 10 rotates around the central axis of the rotating shaft member 20, so that lateral and longitudinal shifting of the vehicle is realized, and therefore, rotation of the shift lever 10 in two directions can be realized only by arranging the rotating shaft member 20 and the shift lever 10, so that the number of parts for supporting, fixing or driving the shift lever 10 can be effectively reduced, the overall structure is simplified, and miniaturization design of the shift operating mechanism 100 is facilitated. Moreover, since the first axis 81 and the second axis 82 intersect, the rotation radius of the shift lever 10 can be reduced, the movement space required by the shift lever 10 during shifting is reduced, the installation space of the shift control mechanism 100 is further reduced, the occupied space in the vehicle is reduced, and the space design of the whole vehicle auxiliary instrument panel is greatly advantageous.

In the present disclosure, how to specifically cooperate the rotating shaft member 20 and the shift lever 10 to realize the rotation of the shift lever 10 about the X direction and the Y direction is not limited, and it can be set as required, as shown in fig. 1-2, the rotating shaft member 20 includes a rotating center portion 21 configured as a spherical structure, the shift lever 10 is opened with a center hole 11 engaged with the rotating center portion 21, the center hole 11 can be configured as a spherical hole, and the rotating shaft member 20 is inserted through the center hole 11. The first axis 81 and the second axis 82 intersect at the spherical center of the rotation center portion 21.

Since the rotation center portion 21 is configured to be a spherical structure, the shift lever 10 can rotate around the X direction and the Y direction relative to the rotation shaft member 20, the spherical structure can ensure the smoothness of rotation in the transverse direction and the longitudinal direction, and since the first axis 81 and the second axis 82 intersect at the spherical center of the rotation center portion 21, the rotation centers during transverse shifting and longitudinal shifting are both at the rotation center portion 21, the rotation radius of the shift lever 10 can be reduced, the movement space required during shifting of the shift lever 10 is reduced, and the miniaturization design of the shift operating mechanism 100 is facilitated.

The spherical characteristic surface of the rotation center part 21 of the rotating shaft member 20, which is matched with the central hole 11 of the gear shift lever 10, needs to reach a certain roughness requirement, and can adopt a processing method of polishing after injection molding, a machining method and the like. The rotation center 21 may be made of metal or high-strength plastic.

Optionally, in an embodiment of the present disclosure, as shown in fig. 1-2, the rotating shaft 20 further includes two supporting portions 22, the supporting portions 22 are disposed on two sides of the rotating central portion 21 along the direction of the second axis 82 and exposed to the central hole 11, and the supporting portions 22 are supported on the base assembly 30.

The support portion 22 allows the rotary shaft member 20 to serve as a rotary shaft during longitudinal shifting, and supports the shift lever 10 by supporting the support portion 22 to the base assembly 30 such that the shift lever 10 is rotatably disposed to the base assembly 30.

Alternatively, in one embodiment of the present disclosure, as shown in fig. 2, the support portion 22 is configured as a cylindrical structure, and the base assembly 30 is provided with a cylindrical hole 31 to be fitted with the cylindrical structure. Since the support portion 22 is configured as a cylindrical structure, when the shift lever 10 is shifted longitudinally, the shaft member 20 can be driven to rotate in the cylindrical hole 31 of the base assembly 30 to some extent.

Optionally, in another embodiment of the present disclosure, as shown in fig. 8, the outer wall of the supporting portion 22 is further provided with a limiting block 221, the base assembly 30 is provided with a limiting groove, and the limiting block 221 cooperates with the limiting groove to limit the supporting portion 22 to rotate around the second axis 82. Due to the limiting function of the limiting block 221 and the limiting groove, when the gear shift lever 10 shifts longitudinally, the rotating shaft member 20 cannot rotate, and the gear shift lever 10 rotates by taking the rotating shaft member 20 as a rotating shaft.

In order to prevent unnecessary shaking in other directions when the shift lever 10 is rotated, as shown in fig. 1 and 2, the outer wall of the central hole 11 is provided with a protrusion 13, the protrusion 13 extends along the first axis 81, and as shown in fig. 5, the base assembly 30 is provided with a sliding groove 321 engaged with the protrusion 13. The chute 321 may be generally configured in an arcuate configuration.

Alternatively, in one embodiment, the projection 13 may be configured as a cylindrical structure, where the first axis 81 is a central axis of the cylindrical structure.

When the gear is shifted longitudinally, the protrusion 13 slides along the arc-shaped side wall of the sliding chute 321, and when the gear is shifted transversely, the protrusion 13 abuts against the side wall of the sliding chute 321, so that the movement of the protrusion in the transverse direction can be limited, the gear shift lever 10 can only rotate around the first axis 81, the gear shifting operation is more stable, and the user experience is better.

In another embodiment of the present disclosure, as shown in fig. 3, the shift operating mechanism 100 further includes a washer member 40. The washer 40 is fixedly disposed in the center hole 11, the rotation shaft 20 is inserted into the washer 40, and the washer 40 has a spherical groove engaged with the rotation center 21.

Alternatively, the washer member 40 is constructed in a generally cylindrical configuration, and the notches 41 provide the washer member 40 with a certain elasticity to facilitate the insertion of the shaft member 20 into the washer member 40 such that the rotation center portion 21 of the shaft member 20 is engaged with the spherical grooves of the washer member 40.

For ease of assembly, in one embodiment of the present disclosure, as shown in fig. 1 and 4, the base assembly 30 includes an upper housing 32 and a lower housing 33. The upper case 32 and the lower case 33 cover each other and form a receiving space. The shift lever 10 includes a body and a rotation shaft portion 12 fitted with a rotation shaft member 20.

The rotating shaft member 20 and the rotating shaft part 12 are arranged in the accommodating space and are covered by the base assembly 30, so that the appearance is better, and the structure is compact.

Optionally, a first semicircular hole 311 is provided on the upper housing 32, a second semicircular hole 312 is provided on the lower housing 33, and the first semicircular hole 311 and the second semicircular hole 312 together constitute the above-mentioned cylindrical hole 31 for cooperating with the supporting portion 22. When mounting, the supporting portion 22 is first disposed on the lower case 33, and then the upper case 32 is covered on the lower case 33.
