Description

Technical Field

[0001] This invention relates to the field of vehicle shock absorption technology, and in particular to a V-shaped vehicle height adjustment system, method, and vehicle. Background Technology

[0002] Existing vehicles typically use air springs, which adjust vehicle height by inflating rubber springs. This not only requires adding a rubber inflation structure to the shock absorbers but also necessitates an additional air tank for the entire vehicle, increasing the cost of the shock absorption system. Furthermore, because air springs are made of rubber, the rubber ages more rapidly with use, potentially leading to air spring leaks and affecting the normal adjustment of vehicle height. Additionally, the limited range of modes offered by traditional air springs restricts vehicle height adjustment to a certain extent. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a V-shaped vehicle height adjustment system, method and vehicle, which uses a V-shaped structure to adjust the vehicle height, and can increase the adjustment range of the vehicle height, and ensure the reliability and continuity of the vehicle height adjustment.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0005] In a first aspect, embodiments of the present invention provide a V-shaped vehicle height adjustment system, including an inner shock absorber and an outer shock absorber, wherein one end of the inner shock absorber and the outer shock absorber are connected to form a V-shaped structure, the other end of the inner shock absorber is engaged with an inner wheel arch vehicle fixed track through an inner adjustment component, and the other end of the outer shock absorber is engaged with an outer wheel arch vehicle fixed track through an outer adjustment component.

[0006] When the inner adjustment component moves to the upper end point of the inner wheel cover fixed track and the outer adjustment component moves to the upper end point of the outer wheel cover fixed track, the angle is the smallest, which is the highest vehicle height mode; when the inner adjustment component moves to the lower end point of the inner wheel cover fixed track and the outer adjustment component moves to the lower end point of the outer wheel cover fixed track, the angle is the largest, which is the lowest vehicle height mode.

[0007] As a further implementation, the inner wheel cover body fixing track and the outer wheel cover body fixing track are parallel to each other.

[0008] As a further implementation, the inner wheel cover body fixing track and the outer wheel cover body fixing track are respectively connected to the lower track via a connecting part.

[0009] As a further implementation, the inner adjustment assembly and the outer adjustment assembly respectively include an inner track for positioning the shock absorber and an outer track for positioning the shock absorber, and the inner track for positioning the shock absorber and the outer track for positioning the shock absorber are connected to the corresponding shock absorbers through the top cover of the shock absorber.

[0010] The inner and outer positioning tracks of the shock absorber are arranged symmetrically with respect to the connecting part and are connected to the connecting part by a drive mechanism.

[0011] As a further implementation, the drive mechanism includes a motor and a drive gear mounted on the motor shaft. The motor is mounted on the corresponding inner track or outer track of the shock absorber positioning. Toothed tracks are provided on both sides of the connecting part, and the drive gear meshes with the toothed tracks.

[0012] Secondly, embodiments of the present invention also provide a working method for a V-shaped vehicle height adjustment system, wherein the inner shock absorber and the outer shock absorber operate synchronously, causing the inner adjustment component to move along the inner wheel arch vehicle fixed track to the upper end of the inner track, while the outer adjustment component moves along the outer wheel arch vehicle fixed track to the upper end of the outer track. At this time, the inner shock absorber and the outer shock absorber are at their highest point with the smallest angle, and the vehicle height is at its highest state.

[0013] The inner adjustment component moves along the inner wheel arch body fixed track to the end point of the inner track downwards, while the outer adjustment component moves along the outer wheel arch body fixed track to the end point of the outer track downwards. At this time, the inner and outer shock absorbers are at their lowest point with the largest angle, and the body height is at its lowest state.

[0014] As a further implementation method, the adjustment process for the maximum vehicle height operating mode is as follows:

[0015] The inner wheel cover motor and the outer wheel cover motor work synchronously, causing the drive gear to move relative to the toothed track. The inner and outer shock absorber positioning tracks move upward along the inner wheel cover body fixed track to the upper end of the inner track.

[0016] At the same time, the motor inside the outer wheel cover and the motor outside the outer wheel cover work synchronously, so that the drive gear moves relative to the toothed track. The inner track and the outer track of the shock absorber positioning move upward along the fixed track of the outer wheel cover body until the angle of the outer track's upward end point is the smallest.

[0017] As a further implementation method, the adjustment process for the minimum vehicle height operating mode is as follows:

[0018] The inner wheel cover motor and the outer wheel cover motor work synchronously, causing the drive gear to move relative to the toothed track. The inner and outer shock absorber positioning tracks move downward along the inner wheel cover body fixed track to the end point of the inner track's downward movement.

[0019] At the same time, the motor inside the outer wheel cover and the motor outside the outer wheel cover work synchronously, causing the drive gear to move relative to the toothed track. The inner track and outer track of the shock absorber positioning move downward along the fixed track of the outer wheel cover body until the angle of the outer track reaches its maximum at the end of the downward movement.

[0020] Thirdly, embodiments of the present invention also provide a vehicle equipped with the aforementioned V-shaped vehicle height adjustment system.

[0021] As a further implementation, the inner wheel cover body fixing track and the outer wheel cover body fixing track are fixed to the body wheel cover.

[0022] The beneficial effects of this invention are as follows:

[0023] (1) This invention changes the single shock absorber on each tire into two shock absorbers arranged in a V-shape. By adjusting the angle of the V-shape structure, the vehicle height can be adjusted. By setting an inner wheel cover fixed track and an outer wheel cover fixed track and configuring a drive mechanism, the inner and outer shock absorbers are simultaneously located at the upper or lower end of the fixed track, thereby placing the vehicle at its highest or lowest position. Furthermore, the inner and outer shock absorbers can be held at any position on the fixed track, thus achieving arbitrary adjustment within the length of the fixed track, increasing the adjustment range of the vehicle height, and achieving the effect of the highest vehicle height at the minimum angle and the lowest vehicle height at the maximum angle.

[0024] (2) The present invention provides the same adjustment components for the inner shock absorber and the outer shock absorber. The adjustment components include symmetrically arranged inner and outer shock absorber positioning tracks. The position adjustment of the inner shock absorber (outer shock absorber) is achieved by moving the inner and outer shock absorber positioning tracks relative to the inner wheel cover body fixed track (outer wheel cover body fixed track), which can increase the durability and sustainability of the system.

[0029] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0030] Example 1:

[0031] To address the issues of traditional air springs being prone to aging and leaking, and unable to adjust vehicle height, this embodiment provides a V-shaped vehicle height adjustment system, including an inner shock absorber and an outer shock absorber arranged in a V-shape. By adjusting the angle of the V-shaped shock absorber, the vehicle height can be adjusted.

[0032] like Figure 1 and Figure 2 As shown, two sets of tracks for adjusting the angle of the shock absorbers are added inside the wheel arches of the vehicle body, namely the inner wheel arch fixed track 1 and the outer wheel arch fixed track 11. The inner wheel arch fixed track 1 and the outer wheel arch fixed track 11 are parallel to each other. The inner wheel arch fixed track 1 is equipped with an inner shock absorber, and the outer wheel arch fixed track 11 is equipped with an outer shock absorber. 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 and outer shock absorbers is the same. This embodiment will use the inner shock absorber as an example for detailed explanation:

[0034] like Figure 1 As shown, a lower rail 5 is provided on the lower side of the inner wheel cover body fixing rail 1, and the inner wheel cover body fixing rail 1 and the lower rail 5 are connected by a connecting part 3. The connecting part 3 is located in the middle of the inner wheel cover body fixing rail 1, so that the two sides of the connecting part 3 form the installation space of the inner adjustment component.

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

[0036] In this embodiment, the drive mechanism includes a motor and a drive gear 7. The motor driving the inner track 4 of the shock absorber is the inner wheel cover motor 2, and the motor driving the outer track 8 of the shock absorber is the inner wheel cover motor 13. Figure 1 In the view direction, the inner wheel cover motor 2 is fixed on the inner track 4 of the shock absorber positioning, and the outer wheel cover motor 13 is fixed on the outer track 8 of the shock absorber positioning.

[0037] The drive gear 7 is mounted on the corresponding motor shaft. The connecting part 3 is symmetrically provided with toothed rails 6. The toothed rails 6 have teeth that mesh with the drive gear 7, forming a gear rack-like mating structure, thereby realizing the movement of the inner track 4 and the outer track 8 of the shock absorber under the drive of the motor.

[0038] like Figure 2 As shown, the end of the inner shock absorber away from the inner wheel arch fixed track 1 is rotatably connected to the connecting shaft via the inner shock absorber column 17, and the end of the outer shock absorber away from the outer wheel arch fixed track 11 is rotatably connected to the connecting shaft 18 via the outer shock absorber column 16. The driving force of the outer shock absorber comes from the inner wheel arch motor 15 and the outer wheel arch motor 14. The shapes of the inner wheel arch fixed track 1 and the outer wheel arch fixed track 11 are adapted to the wheel arch of the vehicle. One end of the inner wheel arch fixed track 1 is the upper end point 19 of the inner track, and the other end is the lower end point 20 of the inner track; one end of the outer wheel arch fixed track 11 is the upper end point 12 of the outer track, and the other end is the lower end point 21 of the outer track.

[0039] Under the synchronous drive of the inner wheel cover motor 2 and the outer wheel cover motor 13, the inner shock absorber moves along the inner shock absorber positioning track 4 and the outer shock absorber positioning track 8 along the toothed track 6 to the upper end point 19 of the inner track; at the same time, under the synchronous drive of the outer wheel cover motor 15 and the outer wheel cover motor 14, the outer shock absorber moves along the inner shock absorber positioning track 4 and the outer shock absorber positioning track 8 along the toothed track 6 to the upper end point 12 of the outer track; at this time, the inner shock absorber and the outer shock absorber are at their highest positions, the angle between the two shock absorbers is the smallest, and the vehicle height is at its highest state.

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

[0041] This embodiment changes the four-wheel shock absorbers from a single one on each tire to two arranged in a V-shape. By adjusting the angle of the V-shape structure, the vehicle height can be adjusted. This reduces the cost of the air spring shock absorption system and improves the durability of the vehicle height adjustment, ensuring the reliability and continuity of the vehicle height adjustment.

[0042] Example 2:

[0043] This embodiment provides a method for operating a V-shaped vehicle height adjustment system. Based on the V-shaped vehicle height adjustment system described in Embodiment 1, the system adjusts the vehicle height between the highest and lowest operating modes, specifically as follows:

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

[0045] When the vehicle body needs to be adjusted to its highest position, after a working signal is transmitted via the central control screen, the inner wheel arch motor 2 and the inner wheel arch motor 13 work synchronously, driving the drive gear 7 to move upward along the inner wheel arch fixed track 1 to the inner track end point 19 within the track space formed by the inner wheel arch fixed track 1, the connecting part 3, and the lower track 5, via the toothed track 6. During this process, the inner shock absorber positioning track 4 and the outer shock absorber positioning track 8 together drive the entire inner shock absorber upward, and the inner shock absorber column 17 also rotates accordingly, moving upward along with the connecting shaft 18. When the movement reaches the inner track end point 19, the inner wheel arch motor 2 and the inner wheel arch motor 13 stop working, and at this time the inner shock absorber is at its highest position.

[0046] Simultaneously, the outer wheel cover motor 14 and the inner wheel cover motor 15 work synchronously, driving the drive gear 7 to move upward along the outer wheel cover body fixed track 11 to the outer track end point 12 within the track space formed by the outer wheel cover body fixed track 11, the connecting part 3, and the lower track 5, via the toothed track 6. During this process, the shock absorber positioning inner track 4 and the shock absorber positioning outer track 8 together drive the entire outer shock absorber upward, and the outer shock absorber column 16 also rotates accordingly, moving upward together via the connecting shaft 18. When it reaches the outer track end point 12, the outer wheel cover motor 14 and the outer wheel cover motor 15 stop working. At this time, the outer shock absorber is at its highest point, with the smallest angle.

[0047] At this point, both the inner and outer shock absorber pillars are at their minimum angle, and the vehicle body is at its highest height.

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

[0049] When the vehicle body needs to be adjusted to its lowest position, after a working signal is transmitted via the central control screen, the inner wheel arch motor 2 and the inner wheel arch motor 13 work synchronously, driving the drive gear 7 to move downwards along the inner wheel arch fixed track 1 to the inner track's lower endpoint 20 within the track space formed by the inner wheel arch fixed track 1, the connecting part 3, and the lower track 5, via the toothed track 6. During this process, the inner and outer shock absorber positioning tracks 4 and 8 together drive the entire shock absorber downwards, with the inner shock absorber column 17 also rotating and moving downwards via the connecting shaft 18. When the inner wheel arch motor 2 and the inner wheel arch motor 13 stop working, the inner shock absorber is at its lowest position.

[0050] Simultaneously, the outer wheel cover motor 14 and the inner wheel cover motor 15 work synchronously, driving the drive gear 7 to move downwards along the outer wheel cover body fixed track 11, the connecting part 3, and the lower track 5 within the track space formed by the outer wheel cover body fixed track 11, passing through the toothed track 6, and driving the shock absorber positioning inner track 4 and the shock absorber positioning outer track 8 to the outer track downward end point 21. During this process, the shock absorber positioning inner track 4 and the shock absorber positioning outer track 8 together drive the entire outer shock absorber downwards, and the outer shock absorber column 16 also rotates accordingly, moving downwards along with the connecting shaft 18. When it reaches the outer track downward end point 21, the outer wheel cover motor 14 and the outer wheel cover motor 15 stop working. At this time, the outer shock absorber is at its lowest point and at its maximum angle.

[0051] At this point, both the inner and outer shock absorber pillars are at their maximum angle, and the vehicle height is at its lowest.

[0052] Similarly, this shock absorber working mode allows for arbitrary angle adjustment within the working track, enabling stepless adjustment of the vehicle height within the track angle. The vehicle can be at any free height, breaking the limitation of traditional air springs having only a few working modes. It also solves the problems of air spring durability and aging, achieving the purpose of vehicle height adjustment at a lower cost.

[0053] Example 3:

[0054] This embodiment provides a vehicle equipped with the V-shaped body height adjustment system described in Embodiment 1, wherein the inner wheel cover body fixing track 1 and the outer wheel cover body fixing track 11 are fixed to the body wheel cover.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
