[0002] In modern automobile manufacturing, safety has always been one of the most important considerations in automobile design. In automobile collisions, especially in collisions in the Z-axis direction, the structure and performance of the shock absorber directly affect the safety performance of the vehicle. However, there are some problems with the existing installation structure of the rear shock absorber of ultra-low cargo platform vehicles, one of which is the insufficient Z-axis stiffness, which may affect the safety performance of the vehicle in Z-axis collisions.
[0003] In view of this, the present utility model is proposed. Utility Model Content
[0004] The present application provides a shock-absorbing mounting reinforcement structure and a vehicle to solve the technical problem that the existing shock-absorbing mounting reinforcement structure has insufficient Z-direction stiffness, which may affect the safety performance of the vehicle during a Z-direction collision.
[0005] The first aspect of the utility model provides a shock-absorbing installation reinforcement structure, including a shock-absorbing reinforcement member and a shock-absorbing connecting member; the shock-absorbing connecting member is arranged in the Y direction facing the shock-absorbing reinforcement member, and the shock-absorbing connecting member is connected to the shock-absorbing reinforcement member and forms a cavity with the shock-absorbing reinforcement member, and the cavity is used to accommodate part of the shock absorber; the shock-absorbing reinforcement member is formed with a first cavity reinforcement rib, a second cavity reinforcement rib and a third cavity reinforcement rib on the side of the shock-absorbing reinforcement member away from the cavity in the Y direction, so as to transmit the Z-direction collision force.
[0006] In this scheme, one side of the shock-absorbing component connecting member forms a cavity with the shock-absorbing reinforcement member to accommodate the shock absorber, and the other side forms a first cavity reinforcement rib, a second cavity reinforcement rib and a third cavity reinforcement rib to transmit the Z-direction collision force respectively; when subjected to a Z-direction collision, the collision force first acts on the surface of the shock-absorbing reinforcement member, and then is transmitted to the rear floor of the vehicle body assembly by the first cavity reinforcement rib, the second cavity reinforcement rib and the third cavity reinforcement rib, and the generated stress is transmitted to the rear floor through the contact surface with the rear floor; in this process, since the shock absorber is directly mounted on the vehicle body assembly, it can be ensured that the shock absorber can better exert its actual performance and improve the driving quality of the vehicle.
[0007] In a further solution of the utility model, the shock-absorbing reinforcement is provided with multiple connection points on the Y-direction facing the cavity side, the multiple connection points are located between the first cavity reinforcement rib and the second cavity reinforcement rib and / or between the second cavity reinforcement rib and the third cavity reinforcement rib, and the shock-absorbing reinforcement is connected to the shock-absorbing connector through the connection points.
[0008] In this solution, by arranging multiple connection points on the side facing the cavity in the Y direction, the connection density between the shock-absorbing reinforcement and the cavity can be increased, thereby enhancing the stability and load-bearing capacity of the entire structure. This can effectively reduce the vibration and deformation of the structure during operation, improving the working efficiency and reliability of the system. The multiple connection points are located between the first cavity reinforcement rib, the second cavity reinforcement rib, and the third cavity reinforcement rib, which can more evenly disperse the force, relieve the pressure on a single connection point, thereby extending the service life of the connecting piece and reducing the risk of structural damage caused by excessive local stress.
[0009] The second aspect of the present utility model provides a vehicle, including a body assembly, a shock absorber, and the shock-absorbing installation reinforcement structure provided in the first aspect of the present utility model.

The arrangement of the shock-absorbing installation reinforcement structure and the shock-absorbing reinforcement can effectively improve the support ability and stability of the vehicle's suspension system, thereby improving the driving stability and handling performance of the vehicle.

[0013] In this solution, the second transverse tie rod reinforcement is used to conduct the Z - direction collision force transmitted by the second cavity rib. Similarly, the first transverse tie rod reinforcement is used to conduct the Z - direction collision force transmitted by the first cavity rib. Subsequently, both transmit the collision force to the second rear longitudinal beam.

The rear floor reinforcement cross beam joint is arranged on the second rear longitudinal beam, and the first rear floor reinforcement cross beam is installed inside the rear floor reinforcement cross beam joint.
[0017] In this solution, by arranging the rear floor reinforcement cross beam joint, the connection stability between the first rear floor reinforcement cross beam and the second rear longitudinal beam can be strengthened, and the conduction performance of the collision force can be optimized.

[0023] In summary, the shock-absorbing mounting and strengthening structure and the vehicle provided by the present application have at least the following beneficial effects:
[0024] One side of the shock-absorbing member connecting piece forms a cavity together with the connecting shock-absorbing strengthening member to accommodate the shock absorber, and the other side forms a first cavity reinforcing rib, a second cavity reinforcing rib, and a third cavity reinforcing rib to transmit the Z-direction collision force respectively; when a Z-direction collision occurs, the collision force first acts on the surface of the shock-absorbing strengthening member, and then is transmitted to the rear floor of the vehicle body assembly by the first cavity reinforcing rib, the second cavity reinforcing rib, and the third cavity reinforcing rib, and the stress generated is transmitted to the rear floor through the contact surface with the rear floor; during this process, since the shock absorber is directly mounted on the vehicle body assembly, it can ensure that the shock absorber can better exert its actual performance and improve the driving texture of the vehicle.
