[0002] Existing vehicles usually install air springs, which adjust the height of the vehicle body by inflating the rubber spring body. Not only does the shock absorber need to add a rubber inflation structure, but the entire vehicle also needs to add a set of air tanks, which increases the cost of the shock absorption system. In addition, since air springs are made of rubber, the increase in the use cycle will accelerate the aging of the rubber. In severe cases, the air spring will leak, affecting the normal adjustment of the vehicle height. At the same time, traditional air springs only have a few state modes, which makes the adjustment of the vehicle height have certain limitations. Summary of the invention

Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0030] Embodiment 1:

[0031] In order to solve the problem that traditional air springs are prone to aging, leakage, and inability to adjust the height of the vehicle body, the present embodiment provides a V-type vehicle height adjustment system, including an inner shock absorber and an outer shock absorber arranged in a V shape. The vehicle height can be adjusted by adjusting the angle of the V-shaped shock absorber.

[0032] like Figure 1 and Figure 2 As shown, two sets of rails for adjusting the angle of shock absorbers are added inside the wheel arch of the vehicle body, namely, the inner wheel arch vehicle body fixed rail 1 and the outer wheel arch vehicle body fixed rail 11, the inner wheel arch vehicle body fixed rail 1 and the outer wheel arch vehicle body fixed rail 11 are parallel to each other, the inner wheel arch vehicle body fixed rail 1 is configured with an inner shock absorber, the outer wheel arch vehicle body fixed rail 11 is configured with an outer shock absorber, and the inner shock absorber and the outer shock absorber are connected to the same connecting shaft 18, so that the inner shock absorber and the outer shock absorber form a V-shaped structure.

[0033] The connection structure of the inner shock absorber and the outer shock absorber is the same, and this embodiment takes the inner shock absorber as an example for detailed description:

[0034] like Figure 1 As shown, a lower track 5 is provided on the lower side of the inner wheel cover vehicle body fixing track 1, and the inner wheel cover vehicle body fixing track 1 and the lower track 5 are connected via a connecting portion 3, and the connecting portion 3 is located in the middle position of the inner wheel cover vehicle body fixing track 1, so that installation space for the inner adjustment component is formed on both sides of the connecting portion 3.

[0035] The inner adjustment component includes a shock absorber positioning inner track 4 and a shock absorber positioning outer track 8, which are symmetrically arranged relative to the connecting part 3, one end of the shock absorber positioning inner track 4 and the shock absorber positioning outer track 8 is a mating end, and the other end is a connecting end, and the connecting ends of the shock absorber positioning inner track 4 and the shock absorber positioning outer track 8 are both connected to the shock absorber top cover 9 and fixed by bolts 10; the mating ends of the shock absorber positioning inner track 4 and the shock absorber positioning outer track 8 are matched with the connecting part 3 through a driving mechanism, and under the action of the driving mechanism, the shock absorber positioning inner track 4 and the shock absorber positioning outer track 8 are moved relative to the inner wheel cover body fixed track 1.

[0036] In this embodiment, the driving mechanism includes a motor and a driving gear 7, the motor for driving the shock absorber to position the inner track 4 is the inner wheel cover inner motor 2, and the motor for driving the shock absorber to position the outer track 8 is the inner wheel cover outer motor 13; Figure 1 In the viewing direction, the motor 2 inside the inner wheel housing is fixed on the shock absorber positioning inner track 4, and the motor 13 outside the inner wheel housing is fixed on the shock absorber positioning outer track 8.

[0037] The driving gear 7 is installed on the corresponding motor shaft, and the toothed tracks 6 are symmetrically arranged on both sides of the connecting part 3. The toothed tracks 6 have gear teeth meshing with the driving gear 7 to form a matching structure similar to a gear rack, thereby realizing the movement of the shock absorber positioning inner track 4 and the shock absorber positioning outer track 8 under the driving action of the motor.

[0038] like Figure 2 As shown, the end of the inner shock absorber away from the inner wheel cover vehicle body fixed track 1 is rotatably connected to the connecting shaft through the inner shock absorber column 17, and the end of the outer shock absorber away from the outer wheel cover vehicle body fixed track 11 is rotatably connected to the connecting shaft 18 through the outer shock absorber column 16; the driving action of the outer shock absorber comes from the outer wheel cover inner motor 15 and the outer wheel cover outer motor 14. The shapes of the inner wheel cover vehicle body fixed track 1 and the outer wheel cover vehicle body fixed track 11 are adapted to the vehicle body wheel cover, one end of the inner wheel cover vehicle body fixed track 1 is the inner track upward terminal 19, and the other end is the inner track downward terminal 20; one end of the outer wheel cover vehicle body fixed track 11 is the outer track upward terminal 12, and the other end is the outer track downward terminal 21.

[0039] Under the synchronous driving action of the motor 2 inside the inner wheel cover and the motor 13 outside the inner wheel cover, the inner shock absorber moves along the toothed track 6 with the shock absorber positioning the inner track 4 and the shock absorber positioning the outer track 8 to the inner track upward terminal 19; at the same time, under the synchronous driving action of the motor 15 inside the outer wheel cover and the motor 14 outside the outer wheel cover, the outer shock absorber moves along the toothed track 6 with the shock absorber positioning the inner track 4 and the shock absorber positioning the outer track 8 to the outer track upward terminal 12; at this time, the inner shock absorber and the outer shock absorber are at the top position, the angle between the two shock absorbers is the smallest, and the vehicle body height is at the highest state.

[0040] Under the synchronous driving action of the motor 2 inside the inner wheel cover and the motor 13 outside the inner wheel cover, the inner shock absorber moves along the toothed track 6 to the inner track downward end 20 along with the shock absorber positioning inner track 4 and the shock absorber positioning outer track 8; at the same time, under the synchronous driving action of the motor 15 inside the outer wheel cover and the motor 14 outside the outer wheel cover, the outer shock absorber moves along the toothed track 6 to the outer track downward end 21 along with the shock absorber positioning inner track 4 and the shock absorber positioning outer track 8; at this time, the inner shock absorber and the outer shock absorber are at the lowest point position, the angle between the two shock absorbers is the largest, and the vehicle body height is at the lowest state.

[0041] In this embodiment, the four-wheel shock absorbers are changed from a single one on each tire to two in a V-shaped arrangement. The height of the vehicle body can be adjusted by adjusting the angle of the V-shaped structure. The cost of the air spring shock absorber system can be reduced, and at the same time the durability of the vehicle height adjustment can be improved, ensuring the reliability and continuity of the vehicle height adjustment.

[0042] Embodiment 2:

[0043] This embodiment provides a working method of a V-type vehicle height adjustment system, which adjusts the vehicle height between the highest working mode and the lowest working mode based on the V-type vehicle height adjustment system described in Embodiment 1. Specifically, the method is as follows:

[0044] (1) Maximum vehicle height working mode:

[0045] When the vehicle body needs to be adjusted to the highest position, after the working signal is transmitted through the central control screen, the inner motor 2 of the inner wheel cover and the outer motor 13 of the inner wheel cover work synchronously, driving the driving gear 7 to drive the shock absorber positioning inner track 4 and the shock absorber positioning outer track 8 to move upward along the inner wheel cover vehicle body fixed track 1 to the inner track upward terminal 19 through the toothed track 6 in the track space formed by the inner wheel cover vehicle body fixed track 1, the connecting part 3 and the lower track 5. In this process, the shock absorber positioning inner track 4 and the shock absorber positioning outer track 8 together drive the entire inner shock absorber to move upward, wherein the inner shock absorber column 17 will also rotate accordingly, and move upward together through the connecting shaft 18. When moving to the inner track upward terminal 19, the inner motor 2 of the inner wheel cover and the outer motor 13 of the inner wheel cover stop working, and the inner shock absorber is at the top position at this time.

[0046] At the same time, the outer motor 14 of the outer wheel housing and the inner motor 15 of the outer wheel housing also work synchronously, driving the driving gear 7 to drive the shock absorber positioning inner track 4 and the shock absorber positioning outer track 8 to move upward along the outer wheel housing body fixed track 11 to the outer track upward terminal 12 through the toothed track 6 in the track space formed by the outer wheel housing body fixed track 11, the connecting part 3 and the lower track 5. In this process, the shock absorber positioning inner track 4 and the shock absorber positioning outer track 8 drive the entire outer shock absorber to move upward, wherein the outer shock absorber column 16 will also rotate accordingly, and move upward together through the connecting shaft 18. When moving to the outer track upward terminal 12, the outer motor 14 of the outer wheel housing and the inner motor 15 of the outer wheel housing stop working, and at this time the outer shock absorber is at the top position with the smallest angle.

[0047] At this time, the inner and outer shock absorber columns are at the minimum angle position and the vehicle body height is at the highest state.

[0048] (2) Minimum vehicle height working mode:

[0049] When the vehicle body needs to be adjusted to the lowest position, after the working signal is transmitted through the central control screen, the inner motor 2 of the inner wheel cover and the outer motor 13 of the inner wheel cover work synchronously, driving the driving gear 7 in the track space formed by the inner wheel cover vehicle body fixed track 1, the connecting part 3 and the lower track 5, and driving the shock absorber positioning inner track 4 and the shock absorber positioning outer track 8 to move downward along the inner wheel cover vehicle body fixed track 1 to the inner track downward terminal 20 through the toothed track 6. In this process, the shock absorber positioning inner track 4 and the shock absorber positioning outer track 8 drive the entire shock absorber to move downward together, wherein the inner shock absorber column 17 will also rotate accordingly, and move downward together through the connecting shaft 18. When moving to the inner track downward terminal 20, the inner motor 2 of the inner wheel cover and the outer motor 13 of the inner wheel cover stop working, and the inner shock absorber is at the lowest point.

[0050] At the same time, the outer motor 14 of the outer wheel housing and the inner motor 15 of the outer wheel housing also work synchronously, driving the driving gear 7 in the track space formed by the outer wheel housing body fixed track 11, the connecting part 3 and the lower track 5, through the toothed track 6, driving the shock absorber positioning inner track 4 and the shock absorber positioning outer track 8 to move downward along the outer wheel housing body fixed track 11 to the outer track downward terminal 21. In this process, the shock absorber positioning inner track 4 and the shock absorber positioning outer track 8 drive the entire outer shock absorber to move downward, wherein the outer shock absorber column 16 will also rotate accordingly, and move downward together through the connecting shaft 18. When moving to the outer track downward terminal 21, the outer motor 14 of the outer wheel housing and the inner motor 15 of the outer wheel housing stop working, and at this time the outer shock absorber is at the lowest point position with the largest angle.

[0051] At this time, the inner and outer shock absorber columns are at the maximum angle position and the vehicle body height is at the lowest state.

[0052] Similarly, the shock absorber working mode in this state can achieve adjustment at any angle within the working track, so that the shock absorber system can achieve stepless adjustment of the vehicle height within the track angle. The vehicle can be at any free height, breaking the problem of traditional air springs having only a few state modes. At the same time, it solves the durability and aging problems of air springs, and achieves the purpose of vehicle height adjustment at a lower cost.
