[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] Before a vehicle leaves the factory, it is necessary to eliminate the assembly stress of the vehicle suspension to ensure that the wheels will not deviate during driving. In the related art, the vehicle stress relief device can usually only eliminate the stress in the Z and X directions of the vehicle, but the stress relief effect on the Y direction of the vehicle is poor, and the release is insufficient, which affects the safety of vehicle driving.

[0031] Reference below Figure 1-Figure 4 A stress relief block according to an embodiment of the present invention is described.

[0032] According to the utility model, the stress release block 1 includes a release block body 11, a support plane 111 is formed at the bottom of the release block body 11, a wheel contact surface 112 is formed at the top of the release block body 11, the release block body 11 extends in a direction perpendicular to the direction of vehicle travel, and the wheel contact surface 112 gradually increases or decreases in the extension direction.

[0033] According to the stress release block 1 of the utility model, a release block body 11 is provided, and the release block body 11 is a structure for eliminating the assembly stress of the vehicle. A support plane 111 is formed at the bottom of the release block body 11, and the support plane 111 can fit with the ground of the vehicle experimental test, thereby improving the stability of the release block during assembly and fixation, and thus avoiding the influence of the release block assembly instability on the vehicle assembly stress elimination process. A wheel contact surface 112 is formed at the top of the release block body 11, that is, when the vehicle eliminates the assembly stress, the wheel can contact the wheel contact surface 112 at the top of the release block body 11, and the stress can be eliminated under the action of the wheel contact surface 112. Specifically, the release block body 11 extends perpendicular to the direction of travel of the vehicle, and the wheel contact surface 112 gradually increases or decreases in height in the extension direction of the release block body 11. When the vehicle passes the wheel contact surface 112, the vehicle will jump in the Z direction and the X direction. At this time, the assembly stress of the vehicle in the Z direction and the X direction can be released. Since the height of the wheel contact surface 112 in the extension direction is variable, here, the height of the wheel contact surface 112 gradually decreases in the extension direction. As an example, when the vehicle passes the wheel contact surface 112, since the height of the wheel contact surface 112 decreases toward one side of the vehicle in the extension direction, the wheel contact surface 112 will give the vehicle a lateral force, causing the vehicle to move laterally or have a tendency to move laterally. At this time, the Y-direction stress of the vehicle is released. The stress release block 1 improves the release efficiency of the vehicle's Y-direction assembly stress through the gradually decreasing or increasing wheel contact surface 112, while taking into account the release of the vehicle's Z-direction and X-direction assembly stress, thereby improving the release effect of the vehicle's overall assembly stress and improving the safety of the vehicle.

[0034] According to an embodiment of the utility model, the height of the release block body 11 gradually decreases in the first direction, and the width of the release block body 11 gradually decreases in the first direction. The first direction can be understood as one of the extension directions of the release block body 11. In the first direction, the height of the release block body 11 gradually decreases, that is, the height of the wheel contact surface 112 gradually decreases. At the same time, the width of the release block body 11 also gradually decreases. When the vehicle passes the stress release block 1, the outer side of the wheel will contact the stress release block 1 before the inner side of the wheel. At this time, the stress release block 1 will apply a force to the wheel that is biased toward the inner side of the wheel, further improving the release efficiency of the vehicle's Y-direction assembly stress. It should be noted that the outer side and the inner side here can be simply understood as the side of the wheel close to the outside of the vehicle during the vehicle's driving as the outer side, and the direction of the wheel close to the other side of the vehicle as the inner side.

[0035] According to an embodiment of the utility model, the wheel contact surface 112 is constructed as an arcuate surface, and a release protrusion 113 is provided on the wheel contact surface 112. When a vehicle passes the stress release block 1, the wheel will hit the release block body 11. At this time, the wheel contact surface 112 constructed as an arcuate surface can reduce the impact of the wheel on the release block body 11, and avoid the stress release block 1 being offset by the impact of the wheel and affecting the release of the vehicle assembly stress. The release protrusion 113 can be provided on the arcuate wheel contact surface 112, and the release protrusion 113 can increase the friction between the wheel contact surface 112 and the wheel, and avoid the wheel from slipping on the wheel contact surface 112, ensuring that the stress release block 1 can release the assembly stress of the vehicle.

[0036] According to an embodiment of the present invention, the release protrusion 113 is configured as a plurality of release protrusions 113 arranged in multiple rows and columns on the wheel contact surface 112. The multiple release protrusions 113 are arranged in multiple rows and columns on the wheel contact surface 112, further improving the friction between the wheel contact surface 112 and the wheel.

[0037] According to an embodiment of the present invention, the release protrusion 113 is provided with a skirt portion 1131 adapted to fit with the wheel contact surface 112 around it. The skirt portion 1131 enables the release protrusion 113 to fit with the arc-shaped wheel contact surface 112, thereby improving the assembly stability of the release protrusion 113.

[0038] In some embodiments, a countersunk hole 101 may be processed on the wheel contact surface 112 for installing an expansion bolt to fix the stress relief block 1 to the ground.

[0039] The stress release device 2 according to the present invention is briefly described below.

[0040] According to the utility model, the stress release device 2 includes a first stress release band 21 and a second stress release band 22, wherein the first stress release band 21 and the second stress release band 22 both include the stress release block 1 in the above-mentioned embodiment. Specifically, the first stress release band 21 is constructed as a plurality of stress release blocks 1 spaced apart in the direction of travel of the vehicle, in the first stress release band 21, the spacing between two adjacent stress release blocks 1 is the same, and the height of any stress release block 1 gradually decreases in the first direction; and the second stress release band 22 is also composed of a plurality of stress release blocks 1 spaced apart in the direction of travel of the vehicle, in the second stress release band 22, the spacing between two adjacent stress release blocks 1 is the same, and the height of any stress release block 1 gradually increases in the first direction; it can also be understood that: after the first stress release band 21 and the second stress release band 22 are assembled and fixed, they correspond to the wheels on the left and right sides of the vehicle respectively, wherein the left wheel passes through the first stress release band 21, and the right wheel passes through the second stress release band 22. When the vehicle passes through the stress release device 2, the first stress release belt 21 applies a force to the vehicle toward the second stress release belt 22, while the second stress release belt 22 applies a force to the vehicle toward the first stress release belt 21. The two stress release belts cooperate with each other to achieve the release efficiency of the vehicle's Y-direction assembly stress, thereby improving the overall stress release efficiency of the vehicle and thereby improving the safety of the vehicle.

[0041] According to an embodiment of the utility model, the stress release blocks 1 in the first stress release belt 21 and the stress release blocks 1 in the second stress release belt 22 are staggered in the direction of travel of the vehicle. When the stress release device 2 is arranged, the stress release blocks 1 in the first stress release belt 21 need to be staggered with the stress release blocks 1 in the second stress release belt 22 to avoid the force applied to the vehicle by the first stress release belt 21 being balanced with the force applied to the vehicle by the second stress release belt 22. When the vehicle passes through the stress release device 2, since the stress release blocks 1 in the two stress release belts are staggered, the vehicle will swing left and right, which can better release the assembly stress of the vehicle in the Y direction.

[0042] According to an embodiment of the utility model, the distance between the first stress release band 21 and the second stress release band 22 is smaller than the closest wheel spacing in the vehicle width direction. When assembling the vehicle to eliminate stress, it is necessary to confirm the distance between the first stress release band 21 and the second stress release band 22 according to the size model of the vehicle, that is, the distance between the first stress release band 21 and the second stress release band 22 needs to be smaller than the closest wheel spacing in the vehicle width direction, so as to ensure that the wheels on both sides of the vehicle in the width direction can be affected by the stress release block 1, and ensure that the stress release device 2 can release the assembly stress of the vehicle in the Y direction.

[0043] According to one embodiment of the utility model, the length of the first stress release band 21 and the length of the second stress release band 22 are both greater than the longest wheel spacing in the length direction of the vehicle. When assembling the vehicle to eliminate stress, it is necessary to confirm the length of the first stress release band 21 and the length of the second stress release band 22 according to the size model of the vehicle. Normally, the length of the first stress release band 21 and the length of the second stress release band 22 should be greater than the longest wheel spacing in the length direction of the vehicle to ensure that the vehicle can pass through the stress release device 2 completely, avoiding the situation where the rear wheel has not yet contacted the stress release device 2 and the front wheel has left the stress release device 2 when the vehicle passes through the stress release device 2, thereby ensuring the effect of the stress release device 2 in releasing the assembly stress of the vehicle. The longest wheel spacing in the length direction of the vehicle mentioned here can also be understood as the length of the vehicle.

[0044] According to an embodiment of the utility model, the width of the first stress release band 21 and the width of the second stress release band 22 are both greater than the width of the wheel. When assembling stress relief of the vehicle, the wheels on both sides of the vehicle can pass through the first stress relief band 21 and the second stress relief band 22 respectively. The width of the first stress relief band 21 and the width of the second stress relief band 22 are respectively greater than the width of the corresponding wheel, so that the wheel can completely contact the corresponding stress relief band, avoiding at least part of the wheel being suspended in the air and affecting the stress relief of the vehicle.

[0045] In some embodiments, the distance between two adjacent stress release blocks 1 in the first stress release band 21 and the distance between two adjacent stress release blocks 1 in the second stress release band 22 need to be smaller than the diameter of the wheel to avoid getting the wheel stuck and ensure that the vehicle can pass through the stress release device 2 normally.
