Description

Technical Field

[0001] This utility model relates to the field of vehicle shock absorption technology, specifically a vehicle shock absorption mechanism. Background Technology

[0002] To adapt to terrain and improve stability during driving, electric vehicles need to be equipped with shock absorbers. Impacts on the wheels are buffered and absorbed by the shock absorbers to reduce the overall impact on the vehicle. Existing electric vehicle shock absorbers generally use a bracket in conjunction with springs for damping. For example, patent publication number CN114768270A discloses a shock absorber and a model vehicle, in which the bracket is elastically connected to a first support via a spring. When the wheel is impacted, the spring force pushes the vehicle body vertically upwards. The large spring force results in significant overall vehicle sway and poor wheel stability.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0028] like Figures 1-3 As shown,

[0029] This embodiment provides a vehicle shock absorption mechanism, which is disposed on the outside of the vehicle body 1, and includes:

[0030] A fixed seat 2 is connected to the wheel frame 11 on both sides of the vehicle body 1. The fixed seat 2 is provided with a rotating groove for accommodating the linkage 3 on the side away from the wheel frame 11. The linkage 3 is rotatably disposed in the rotating groove through the first pin 5. Two sets of linkage 3 are symmetrically arranged and are respectively installed on both sides of the rotating groove. The side of the linkage 3 away from the fixed seat 2 is rotatably connected to the adjusting seat 4 through the second pin 6, so that the adjusting seat 4, the linkage 3 and the fixed seat 2 form a parallel linkage structure.

[0031] A shock absorber 7 is provided between the fixed seat 2 and the adjusting seat 4 with elastic connection. A rotating sleeve 71 is provided on both sides of the shock absorber 7. The rotating sleeve 71 on one side of the shock absorber 7 is installed on the upper end of the fixed seat 2 through the first pin 5, and the rotating sleeve 71 on the other side of the shock absorber 7 is installed on the lower end of the adjusting seat 4 through the second pin 6.

[0032] Specifically, the adjusting seat 4, the linkage 3, and the fixed seat 2 in this device form a parallel linkage structure, and the shock absorber 7 is located between the adjusting seat 4 and the fixed seat 2, effectively reducing the overall size and improving the compactness of the structure. The linkage 3 and the shock absorber 7 are mounted on one side of the fixed seat 2 via the first pin 5, and on the other side via the second pin 6, simplifying assembly and improving efficiency. The shock absorber 7 is rotatably mounted on the first pin 5 and the second pin 6 on both sides. When the adjusting seat 4 is impacted and moves upwards in parallel, one side of the shock absorber 7 also moves upwards, thereby reducing the upward force on the vehicle body 1 and improving vehicle stability.

[0033] To increase the movement space of the linkage 3 and the rotating sleeve 71 in the rotating groove and to prevent the outer side of the linkage 3 and the rotating sleeve 71 from contacting the inner sidewall of the rotating groove, in order to solve the above problems, in one embodiment of the present invention, the fixed base 2 is integrally provided with outwardly extending clamping plates 21 on both sides of the rotating groove. The clamping plates 21 are respectively arranged on both sides of the upper end of the fixed base 2 to correspond to the two sets of linkages 3.

[0034] The adjusting seat 4 has a transition frame 41 connected to the linkage 3 on one side. The transition frame 41 has a U-shaped structure and is respectively set at the upper and lower ends of the adjusting seat 4 to correspond to two sets of linkages 3. The linkage 3 is inserted into the inner groove of the transition frame 41 and is connected to the transition frame 41 and the linkage 3 by the second pin 6 passing through it.

[0035] The linkage 3 includes a first linkage plate 31 and a second linkage plate 32 spaced apart. The outer sides of the first linkage plate 31 and the second linkage plate 32 are fixed together by a support plate 33. A groove is formed between the first linkage plate 31 and the second linkage plate 32. One side of the first linkage plate 31 and the second linkage plate 32 are slidably attached to the inner side wall of the clamping plate 21, and the other side is slidably attached to the inner side wall of the adapter frame 41.

[0036] The rotating sleeves 71 on both sides of the shock absorber 7 are respectively disposed between the first connecting plate 31 and the second connecting plate 32. The two sides of the rotating sleeves 71 are slidably attached to the first connecting plate 31 and the second connecting plate 32 to improve the stability of the rotating connection.

[0037] Because the shock absorber 7 is built between the two connecting members 3, the connecting members 3 will come into contact with the shock absorber 7 during rotation. In order to improve the range of motion of the shock absorber 7 and solve the above problem, in one embodiment of this utility model, the first connecting plate 31 and the second connecting plate 32 are arc-shaped plate structures, and the first connecting plate 31 and the second connecting plate 32 are provided with arc-shaped grooves on the side facing the shock absorber 7 to improve the range of motion of the shock absorber 7.

[0038] The shock absorber 7 includes a telescopic movable rod 72 and a shock-absorbing spring sleeved on the outer end of the movable rod 72. The movable rod 72 is provided with spring plates 73 on both sides to limit the shock-absorbing spring 74. The rotating sleeves 71 are fixedly installed on both sides of the movable rod 72.

[0039] The adjusting seat 4 is equipped with a wheel seat 8 for mounting a wheel. The adjusting seat 4 has an axle hole corresponding to the wheel seat, and a bearing 42 is installed in the axle hole. A rotating shaft 81 is provided on one side of the wheel seat and inserted into the bearing 42 so that the wheel seat can be rotatably mounted on the adjusting seat 4.
