Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to an adjustment structure of a shock absorber and a vehicle. Background Art

[0002] The accuracy of the vertical distance from the upper edge of the vehicle tire to the lower edge of the wheel arch affects the center of mass height and aesthetic appearance of the vehicle. During the trial production stage of the test vehicle, due to manufacturing tolerances, the vertical distance from the upper edge of the tire to the lower edge of the wheel arch of the test vehicle may be higher or lower than the design value. If the distance is designed to be low, the center of mass of the vehicle will be lower than the design value. In this state, the vehicle will have a smaller roll angle when cornering and a smaller pitch angle when accelerating and decelerating. If the chassis adjustment for sports performance is carried out in this state, the parameters of the chassis components such as springs, stabilizer bars, and shock absorbers after adjustment will be installed on a mass-produced vehicle with complex requirements. Since the center of mass of the mass-produced vehicle is higher than that of the test vehicle, the roll and pitch angles of the mass-produced vehicle will be larger than those of the test vehicle, resulting in unsatisfactory performance. Therefore, before carrying out chassis adjustment, it is necessary to adjust the vertical distance from the upper edge of the tire to the lower edge of the wheel arch in the test vehicle.

By replacing springs of different lengths, the height of the upper spring support is adjusted, the vehicle body is raised, and the vertical distance from the upper edge of the vehicle tire to the lower edge of the wheel arch is changed. However, if the measurement results do not meet the requirements after the shock absorber is installed, it needs to be disassembled repeatedly. This solution replaces the spring many times, and each time the spring is replaced, the tire, shock absorber and other components need to be disassembled, which has low work efficiency.

[0029] Various aspects and features of the present invention are described herein with reference to the accompanying drawings.

[0030] It should be understood that various modifications may be made to the embodiments of the present application. Therefore, the above description should not be considered as limiting, but only as an example of the embodiments. Other modifications within the scope and spirit of the present utility model will occur to those skilled in the art.

[0031] The accompanying drawings, which are included in and constitute a part of the specification, illustrate embodiments of the present invention and, together with the general description of the present invention given above and the detailed description of the embodiments given below, are used to explain the principles of the present invention.

[0032] These and other characteristics of the invention will become apparent from the following description of a preferred form of embodiment given as a non-limiting example, with reference to the accompanying drawings.

[0033] It should also be understood that although the present invention has been described with reference to some specific examples, those skilled in the art will be able to realize many other equivalent forms of the present invention that have the features described in the claims and are therefore within the scope of protection defined thereby.

[0034] The above and other aspects, features and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0035] Specific embodiments of the present invention are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present invention, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present invention. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use the present invention in a variety of ways with substantially any suitable detailed structure.

[0036] The first embodiment of the utility model provides an adjustment structure of a shock absorber, such as Figure 1 and Figure 2 As shown, the adjustment structure of the shock absorber includes a shock absorber, an upper spring support 1, a lower spring support 2 and a spring 3. The shock absorber includes a shock absorber tube 4. The lower spring support 2 is movably sleeved on the outer periphery of the shock absorber tube 4. The upper spring support 1 is connected to the shock absorber tube 4 and is located above the lower spring support 2. The spring 3 is arranged between the upper spring support 1 and the lower spring support 2. A plurality of step portions 5 are provided on the lower spring support 2 along its axial direction. A support portion 6 cooperating with the step portion 5 is provided on the outer periphery of the shock absorber tube 4. The lower spring support 2 can rotate relative to the shock absorber tube 4 so that the support portion 6 is connected to the corresponding step portion 5, thereby adjusting the height of the lower spring support 2.

[0037] The upper spring support 1 and the lower spring support 2 are used to constrain the spring 3. The step portion 5 is a stepped structure with different heights arranged along the axial direction of the lower spring support 2, which can be matched with the support portion 6 arranged on the outer periphery of the shock absorber cylinder 4. The lower spring support 2 is sleeved on the outer periphery of the shock absorber cylinder 4 and is movably connected to the shock absorber cylinder 4. The support portion 6 arranged along the side of the shock absorber cylinder 4 is connected to one of the step portions 5, which can support the lower spring support 2 and prevent the lower spring support 2 from axial movement when the lower spring support 2 is not rotated; in addition, by rotating the lower spring support 2, the lower spring support 2 can rotate around the shock absorber cylinder 4, so that the support portion 6 can be matched with another step portion 5, thereby adjusting the height of the lower spring support 2. The spring 3 has a certain amount of pre-compression when installed on the upper spring support 1 and the lower spring support 2. The change in the height of the lower spring support 2 will change the compression degree of the spring 3 and thus cause the height of the lower spring support 2 to change. Then, the upper spring support 1 is used to lift or lower the vehicle body, and the vertical distance from the upper edge of the vehicle tire to the lower edge of the wheel arch is changed. By rotating the lower spring support 2 to change the coordination between the support portion 6 and the step portion 5 at different positions, the height of the lower spring support 2 can be adjusted, and then the upper spring support 1 can be used to lift or lower the vehicle body. The vertical distance from the upper edge of the tire to the lower edge of the wheel arch can be quickly adjusted, and there is no need to replace the spring 3 multiple times, disassemble the wheels and shock absorbers and other components, and improve work efficiency. At the same time, there is no need to prepare springs 3 of various lengths to meet the debugging requirements of the test vehicle, saving development costs.

[0038] The utility model can adjust the vertical distance from the upper edge of the tire to the lower edge of the wheel arch only through the upper spring support 1, the lower spring support 2 and the spring 3, does not need to use parts with complex structures, and has a simple assembly process.

[0039] The shock absorber further comprises a shock absorber upper support 7 and a shock absorber lower support 8, wherein the shock absorber upper support 7 is connected to the spring upper support 1, the shock absorber upper support 7 is connected to the vehicle body, the shock absorber lower support 8 is connected to the shock absorber cylinder 4, and the shock absorber lower support 8 is connected to the wheel through a swing arm or a steering knuckle. The shock absorber upper support 7 serves to connect the shock absorber and the vehicle body, and the shock absorber lower support 8 serves to connect the shock absorber and the wheel. The shock absorber upper support 7 and the shock absorber lower support 8 ensure the installation strength of the shock absorber.

[0040] like Figure 3 As shown, a piston rod 9 is provided on the top of the shock absorber cylinder 4, and the spring upper support 1 is connected to the piston rod 9. At least part of the piston rod 9 extends into the shock absorber cylinder 4 and is movably connected to the shock absorber cylinder 4, and one end of the piston rod 9 extending out of the shock absorber cylinder is connected to the spring upper support 1. The piston rod 9 plays a guiding role in the process of the spring 3 extending or compressing.

[0041] Specifically, Figures 1 to 4 As shown, the adjustment structure of the shock absorber is described by taking the initial position where the support part 6 cooperates with the highest step part 5 as an example. The initial position is that the support part 6 cooperates with the highest step part 5, and the height of the lower spring support 2 is the lowest. By rotating the lower spring support 2 to make the support part 6 cooperate with a step part 5 with a lower height, the height of the lower spring support 2 increases, the distance between the lower spring support 2 and the upper spring support 1 decreases, and the pressure on the spring 3 increases. Subsequently, the spring 3 releases the pressure and lifts the upper spring support 1, and then the upper spring support 1 connected to the vehicle body lifts the vehicle body, and the vertical distance from the upper edge of the tire to the lower edge of the wheel arch increases.

[0042] Furthermore, if the initial position is that the support portion 6 cooperates with the step portion 5 with the lowest height, at this time, the height of the lower spring support 2 is the highest. By rotating the lower spring support 2 to make the support portion 6 cooperate with a step portion 5 with an increased height, the height of the lower spring support 2 is reduced, the distance between the lower spring support 2 and the upper spring support 1 is increased, and the pressure on the spring 3 becomes smaller. Subsequently, the height of the upper spring support 1 is reduced, and the upper spring support 1 connected to the vehicle body reduces the height of the vehicle body, and the vertical distance from the upper edge of the tire to the lower edge of the wheel arch is reduced.

[0043] The initial position may also be the position where the support portion 6 cooperates with any step portion 5 .

[0044] The spring support 2 includes a connecting sleeve 21, and a plurality of step portions 5 are arranged at the bottom of the connecting sleeve 21, and the plurality of step portions 5 are sequentially upward along the circumferential direction of the connecting sleeve 21. Specifically, the spring support 2 is continuously rotated in a specific direction, and the support portion 6 cooperates with the step portions 5 of different heights to realize the continuous increase or decrease in the height of the spring support 2, thereby realizing the raising or lowering of the vehicle body, and the operation is simple. In some embodiments, the spring support 2 is rotated clockwise, the height of the spring support 2 is reduced, and the vehicle body is lowered; the spring support 2 is rotated counterclockwise, the height of the spring support 2 is increased, and the vehicle body is lowered. Among them, each time the spring support 2 rotates a fixed angle, the spring support 2 changes a rated distance. In one operation, the spring support 2 can be changed by a rated distance, or it can be changed by multiple rated distances.

[0045] The top edge of the connecting sleeve 21 is provided with a support plate 22 connected to the spring 3. The support plate 22 and the spring upper support 1 provide a mounting position for the spring 3, wherein, since the support plate 22 needs to reserve a space to prevent the spring 3 from moving, the diameter of the support plate 22 is not less than the diameter of the connecting sleeve 21.

[0046] The support portion 6 includes a support column 61 extending outward from the side wall of the shock absorber cylinder 4. The smooth structure of the surface of the support column 61 enables it to stably and smoothly complete the cooperation with the step portion 5 when it cooperates with the step portion 5, and the smooth support column 61 structure can be adapted to support portions 6 of various shapes, and has good versatility.

[0047] In some embodiments, the support portion 6 is welded to the shock absorber cylinder 4, and the structure is more stable.

[0048] In some embodiments, the support portion 6 further includes a limiting portion 62 disposed at the end of the support column 61. The limiting portion 62 is disposed at an end of the support column 61 away from the shock absorber cylinder 4, and the setting of the limiting portion 62 plays a limiting role in the radial direction of the spring lower support 2.

[0049] In some embodiments, Figure 4 As shown, a plurality of step portions 5 are sequentially connected along the circumferential direction of the connecting sleeve 21, so that each step portion 5 corresponds to a height position, and different step portions 5 correspond to different heights. In this way, the support portion 6 can switch faster in cooperation with two different step portions 5, that is, the spring lower support 2 can quickly achieve height adjustment.

[0050] In this embodiment, a limiting structure 51 is formed between two adjacent step portions 5, and the limiting structure 51 serves to limit the support portion 6. When the support portion 6 is adjusted to be connected to one of the step portions 5, it prevents the support portion 6 from moving and cooperating with other step portions 5 when there is no need to adjust the vehicle body height (without rotating the spring lower support 2).

[0051] In other embodiments, Figure 5 As shown, a plurality of step portions 5 are arranged at intervals along the circumferential direction of the connecting sleeve 21, and two adjacent step portions 5 have a platform 52 whose height does not change. The arrangement of the platform 52 ensures that when the height of the spring lower support 2 is adjusted, the height change of the spring lower support 2 will not change suddenly.

[0052] In some embodiments, the step portion 5 is an arc portion (arc-shaped). The outer periphery of the support column 61 is in point contact with the arc portion, and the rolling friction between the two is smaller, which saves more effort when rotating the spring lower support 2, and the support column 61 and the arc portion move relative to each other more smoothly.

[0053] For example, Figure 2 and Figure 4 As shown, the arc-shaped portions are connected in a stepped manner from bottom to top, so that different arc-shaped portions are located at different axial heights of the connecting sleeve 21. At the same time, it is convenient for the connecting sleeve 21 to rotate smoothly with the support column 61, and the support column 61 can be smoothly engaged with the corresponding arc-shaped portion.

[0054] The arc-shaped portion includes an arc-shaped body that bends upward and a concave snap-in position that is recessed upward. The arc-shaped body is used to cooperate with the support column 61 to facilitate the smooth rotation of the connecting sleeve 21. The concave snap-in position is arranged at the top (tail) of the arc-shaped body to facilitate the support column 61 to engage with the concave snap-in position after the connecting sleeve 21 rotates.

[0055] In this embodiment, the tail of the concave position is downward (the tail of the arc portion is downward), and the head of the arc portion is upward, so that a V-shaped limiting structure 51 can be formed between adjacent arc portions to prevent the support column 61 from moving to connect with other arc portions, so that the rotated spring lower support 2 and the shock absorber cylinder 4 are reliably fixed.

[0056] In some embodiments, the lengths of the arc-shaped portions are the same, and the rotation angle of the connecting sleeve 21 can be uniformly set, and then the adjustment height of the spring lower support 2 can be uniformly set according to the rotation angle of the rotating sleeve, so that the connecting sleeve 21 can be rotated to the corresponding position according to the needs, and the height of the spring lower support 2 can be adjusted. In addition, the lengths of the arc-shaped portions are set to be the same, which is convenient for processing and forming at the bottom end of the connecting sleeve 21, and the cost is low. In specific implementations, the lengths of the arc-shaped portions can also be set according to actual needs. For example, the lengths of the arc-shaped portions can be increased in sequence in an arithmetic progression.

[0057] In other embodiments, the step portion 5 may be a U-shaped portion, a V-shaped portion, or a toothed portion, etc. For example, the U-shaped groove of the U-shaped portion may be engaged with the support column 61 to fix the rotating connecting sleeve 21, and the curvature of the U-shaped portion may be set larger to facilitate smooth rotation of the connecting sleeve 21.

[0058] In some embodiments, Figure 6 As shown, the support columns 61 are symmetrically arranged on both sides of the shock absorber cylinder 4, and the connecting sleeve 21 includes a first connecting section 211 and a second connecting section 212 respectively matched with the two support columns 61, and the first connecting section 211 and the second connecting section 212 respectively include a plurality of step portions 5 from bottom to top, and the tail of the first connecting section 211 corresponds to the head of the second connecting section 212. There are two support columns 61 symmetrically arranged, the step portion 5 in the first connecting section 211 corresponds to one of the support columns 61, and the step portion 5 in the second connecting section 212 corresponds to the other support column 61, and the first connecting section 211 and the second connecting section 212 are respectively arranged on both sides of the shock absorber cylinder 4, and cooperate with the two symmetrically arranged support columns 61 to improve the stability of the adjustment process.

[0059] In other embodiments, two groups of support columns 61 are provided, and the two support columns 61 in each group of support columns 61 are symmetrically arranged. The connecting sleeve 21 includes four connecting sections, and each support column 61 corresponds to a connecting section. Multiple support columns 61 are provided to improve stability during the adjustment process.
