[0030] The following is for reference. Figures 1-7 A limiting fixture 100 for a gear shift lever 200 according to an embodiment of the first aspect of the present invention is described.

[0031] like Figures 1-7 As shown, the limiting fixture 100 of the gear shift lever 200 according to the first aspect of the present invention includes a first limiting segment 1 and two second limiting segments 2.

[0032] Specifically, the first limiting segment 1 is along the first direction (e.g., Figure 1 The two second limiting segments 2 are both located on the same side of the first limiting segment 1 in the first direction, and the two second limiting segments 2 are respectively located on the first limiting segment 1 in the second direction (e.g., in the vertical direction). Figure 1 At both ends of the left and right directions, each second limiting segment 2 is along a third direction (e.g., Figure 1 The first limiting segment 1 extends in the front-back direction, and the third, second, and first directions are orthogonal to each other. The other end of the first limiting segment 1 in the first direction is adapted to abut against the rotation shaft 201 of the gear shift lever 200, and a portion of the first limiting segment 1 and a portion of the second limiting segment 2 are adapted to abut against the surface of the gear shift lever 200.

[0033] For example, in Figures 1-7In the example, two second limiting segments 2 are respectively located on both sides of the first limiting segment 1 in the second direction, so that the first limiting segment 1 limits the gear shift lever 200 on one side in the third direction, and the second limiting segment 2 limits the gear shift lever 200 on both sides in the second direction. Thus, the limiting fixture 100 can limit the gear shift lever 200 on three sides, minimizing the offset of the gear shift lever 200, reducing the deviation generated during installation, increasing the stability and reliability of the gear shift lever 200 installation, and ensuring the assembly consistency of the gear shift lever 200.

[0034] The cooperation between the first limiting segment 1 and the rotating shaft 201 of the gear shift lever 200, as well as the cooperation between part of the first limiting segment 1 and part of the second limiting segment 2 and the surface of the gear shift lever 200, helps to increase the stability of the cooperation between the limiting fixture 100 and the gear shift lever 200, and at the same time helps to ensure the assembly consistency of the gear shift lever 200.

[0035] Therefore, during the assembly of the gear shift lever 200, the limiting fixture 100 is installed on the gear shift lever 200, so that the first limiting segment 1 abuts against the rotating shaft 201 of the gear shift lever 200, and a portion of the first limiting segment 1 and a portion of the second limiting segment 2 abut against the surface of the gear shift lever 200. Then, the shift cable of the gear shift lever 200 is assembled, and the shift lever 200's actuator and gearbox are connected. Finally, after the assembly and adjustment of the gear shift lever 200 are completed, the limiting fixture 100 is removed.

[0036] According to an embodiment of the present invention, the limiting fixture 100 of the gear shift lever 200 stops the gear shift lever 200 by having a first limiting segment 1 of the limiting fixture 100 abut against the rotation shaft 201 of the gear shift lever 200, and a portion of the first limiting segment 1 and a portion of the second limiting segment 2 abut against the surface of the gear shift lever 200. This achieves the limiting of the gear shift lever 200 by the limiting fixture 100, increases the stability and reliability of the installation of the gear shift lever 200, reduces the deviation generated by the gear shift lever 200 during the installation process, and ensures the assembly consistency of the gear shift lever 200.

[0037] According to some embodiments of the present invention, with reference to Figure 1 , Figure 2 and Figure 4 and combined Figure 6 and Figure 7The first limiting segment 1 is recessed at its other end in the first direction towards the second limiting segment 2 to form an arc-shaped groove 11. In the third direction, the arc-shaped groove 11 penetrates the first limiting segment 1 and engages with the rotating shaft 201. That is, the first limiting segment 1 has an arc-shaped groove 11 formed at its end in the first direction away from the two second limiting segments 2, and the arc-shaped groove 11 is suitable for engaging with the rotating shaft 201 of the gear shift lever 200. The engagement of the arc-shaped groove 11 with a portion of the rotating shaft 201 along the axial direction of the rotating shaft 201 helps increase the stability of the engagement between the limiting fixture 100 and the gear shift lever 200.

[0038] Furthermore, referring to Figure 1 , Figure 2 and Figure 4 and combined Figure 6 and Figure 7 The arc-shaped groove 11 includes a first sub-arc-shaped groove 111 and a second sub-arc-shaped groove 112 that are interconnected. The first sub-arc-shaped groove 111 and the second sub-arc-shaped groove 112 are arranged along a third direction, and the inner diameter of the first sub-arc-shaped groove 111 is larger than the inner diameter of the second sub-arc-shaped groove 112. The arrangement of the first sub-arc-shaped groove 111 and the second sub-arc-shaped groove 112 facilitates the cooperation between the arc-shaped groove 11 of the first limiting section 1 and the rotating shaft 201, further increasing the stability of the cooperation between the limiting fixture 100 and the gear shift lever 200. Alternatively, when the second sub-arc-shaped groove 112 is in cooperation with the rotating shaft 201, the first sub-arc-shaped groove 111 avoids some structures of the gear shift lever 200, increasing the reliability of the limiting fixture 100 on the gear shift lever 200.

[0039] Furthermore, referring to Figure 4 In the second direction, the length of the second sub-arc groove 112 is greater than or equal to half the length of the arc groove 11. This arrangement ensures that the mating area between the limiting fixture 100 and the rotating shaft 201 is large, thereby increasing the limiting reliability and stability of the limiting fixture 100 on the gear shift lever 200, which in turn helps to improve the conversion efficiency of the gear shift lever 200 and the assembly accuracy of the gear shift lever 200.

[0040] In addition, such as Figure 4As shown, the length of the arc-shaped groove 11 in the third direction is L1, where L1 satisfies: 20mm≤L1≤30mm. When the length of the arc-shaped groove 11 in the third direction is less than 20mm, the length of the arc-shaped groove 11 is small, the structural strength of the corresponding first limiting segment 1 is small, and the stop area between the first limiting segment 1 and the rotation shaft 201 of the gear shift lever 200 is small, which easily reduces the stability of the fit between the limiting fixture 100 and the gear shift lever 200. When the length of the arc-shaped groove 11 in the third direction is greater than 30mm, the length of the arc-shaped groove 11 is large, requiring the rotation shaft 201 of the gear shift lever 200 to provide a larger fit area, which easily reduces the applicability of the limiting fixture 100. Therefore, by setting the length of the arc groove 11 in the third direction to 20mm≤L1≤30mm, the length of the arc groove 11 is more reasonable, ensuring the mating area between the limit fixture 100 and the rotating shaft 201, improving the limit fixture 100's limiting reliability and stability for the speed control lever 200, and increasing the applicability of the limit fixture 100, which is conducive to enhancing the market competitiveness of the limit fixture 100.

[0041] According to some embodiments of the present invention, with reference to Figures 1-4 , combined Figure 6 and Figure 7 Each second limiting segment 2 has a limiting block 21 at its end away from the first limiting segment 1. The limiting block 21 has an inclined surface on the side away from the first limiting segment 1 in the second direction, extending towards the first limiting segment 1 in the first direction. Therefore, the limiting block 21 increases the surface area of ​​the limiting fixture 100 and the gear shift lever 200, further improving the limiting, fixing, and reliability of the limiting fixture 100 on the gear shift lever 200. The inclined arrangement of the limiting block 21 towards the first limiting segment 1 helps reduce the area of ​​the end of the limiting block 21 facing the first limiting segment 1 in the first direction, facilitating the assembly of the limiting block 21 onto the gear shift lever 200.

[0042] Furthermore, referring to Figure 3The length of the limiting block 21 in the first direction is L2, where L2 satisfies: 20mm ≤ L2 ≤ 40mm. When the length of the limiting block 21 in the first direction is less than 20mm, the length of the limiting block 21 is small, and the contact area between the limiting block 21 and the gear shift lever 200 is small, resulting in low reliability of the gear shift lever 200 being limited to both sides of the second limiting segment 2. When the length of the limiting block 21 in the first direction is greater than 40mm, the length of the limiting block 21 is large, and the size of the limiting block 21 is large, which is not conducive to the lightweight design of the limiting fixture 100. Therefore, by setting the length of the limiting block 21 in the first direction to 20mm ≤ L2 ≤ 40mm, the size of the limiting block 21 is more reasonable, which is conducive to improving the reliability of the gear shift lever 200 being limited to both sides of the second limiting segment 2, while also facilitating the lightweight design of the limiting fixture 100.

[0043] According to some embodiments of the present invention, with reference to Figure 1 and Figure 3 The thickness of the first limiting segment 1 in the second direction gradually increases in the direction away from the second limiting segment 2. That is, the thickness of the first limiting segment 1 at the end adjacent to the second limiting segment 2 in the second direction is smaller, and the thickness of the second limiting segment 2 at the end away from the second limiting segment 2 in the second direction is larger. This ensures the stability of the stop fit between the first limiting segment 1 and the rotating shaft 201, while also facilitating the lightweight design of the first limiting segment 1.

[0044] According to some embodiments of the present invention, such as Figure 1 , Figure 2 and Figure 7 As shown, at least one weight-reducing hole 12 is formed on the first limiting segment 1. Two weight-reducing holes 12 are formed on the first limiting segment 1, and both weight-reducing holes 12 penetrate along a third direction. This ensures the structural strength of the first limiting segment 1 while facilitating the lightweight design of the first limiting segment 1 and the limiting fixture 100, making it easier for the user to move the limiting fixture 100.

[0045] According to a second aspect of the present invention, a vehicle processing apparatus (not shown) includes a limiting fixture 100 for a gear shift lever 200 according to the first aspect of the present invention described above.

[0046] According to the vehicle processing equipment of the present invention, the limiting fixture 100 of the gear shift lever 200 helps to increase the assembly consistency of the gear shift lever 200, improve the assembly efficiency of the gear shift lever 200, and thus improve the assembly efficiency of the vehicle.
