[0004] Based on the above retrieval and combined with the prior art, it is found that;

[0005] The shock absorption device set in the above patent can only be adjusted simultaneously during pitching or rolling, and cannot be adjusted according to different motion states. Moreover, the shock absorption adjustment device occupies a large volume and has a high weight, which has an adverse effect on the layout of the whole vehicle. Therefore, there are certain limitations. Summary of the Utility Model

[0006] In order to solve the above technical problems, the utility model provides a shock absorption device for racing cars. In this device, the tension of the shock absorber connecting rod is converted into thrust and acts on the shock absorption system through a connecting rod, so that the shock absorption system can be placed at the bottom of the vehicle, reducing the center of gravity of the whole vehicle.

[0007] The technical solution for achieving the purpose of the utility model is: a shock absorption device for racing cars, including a fixing frame. A pair of support rods are rotatably installed at the bottom of the fixing frame through a movable shaft. At the bottom of each of the pair of support rods, a connecting V-shaped block one is rotatably installed through a movable shaft. A shock absorber one is rotatably installed between the pair of connecting V-shaped blocks one through a movable shaft. One end of the pair of support rods is rotatably installed with an installation frame through a movable shaft.

[0008] Preferably, a fixing frame is fixedly installed at one end of the installation frame, a sliding frame is slidably installed at the other end of the installation frame, a sliding groove is formed at one end of the installation frame close to the sliding frame, and the sliding frame is slidably matched with the sliding groove.

[0009] Preferably, a shock absorber two is rotatably installed between the sliding frame and the fixing frame through a movable shaft together.

[0010] Preferably, one end of the connecting V-shaped block one is rotatably installed with a connecting block through a movable shaft, both sides of the fixing frame are rotatably installed with connecting V-shaped blocks two through movable shafts, and the connecting V-shaped block two and the connecting block are rotatably connected through a movable shaft.

[0011] Preferably, one end of the connecting V-shaped block two far from the connecting block is rotatably installed with a connecting rod through a movable shaft.

[0012] Compared with the prior art, the remarkable advantages of this utility model are:

[0013] First: In this utility model, the two shock absorbers are not arranged on the same axis. Through a mechanism, the function of one shock absorber is changed from providing thrust to providing tension. The motion state of the vehicle is transmitted to the two shock absorbers through a connecting rod. When the vehicle is pitching, the horizontally arranged shock absorber is compressed, while the non-horizontally arranged shock absorber remains unchanged in length and is not affected by any force. When the vehicle is in a roll state, the horizontal shock absorber is not affected by force, while the non-horizontally arranged shock absorber is subjected to tension. By using this arrangement method, not only the complexity of adjusting the suspension is reduced, but also the volume occupied by the shock absorption system is greatly reduced, and the anti-roll bar design is cancelled, thereby reducing the weight of the whole vehicle.

[0014] Second: In this utility model, the tension of the shock absorber connecting rod is converted into thrust and acts on the shock absorption system through a connecting rod, and the layout method of the tie rod suspension is used. Thus, the shock absorption system can be placed at the bottom of the vehicle, reducing the center of gravity of the whole vehicle, reducing the adverse impact on the aerodynamics of the whole vehicle, and making the driver's field of vision wider.

[0015] It solves the problem that the shock absorption device set in the retrieved patent can only be adjusted simultaneously when pitching or rolling, cannot be adjusted according to different motion states, and the shock absorption adjustment device occupies a large volume and has a high weight, which has an adverse impact on the layout of the whole vehicle.

[0023] The present utility model will be described in detail below. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0024] The present utility model provides a shock absorption device for a racing car by improvement. The technical solution of the present utility model is as follows:

[0025] As Figures 1-4 shown, a shock absorption device for a racing car includes a fixed frame 1. A pair of support rods 2 are rotatably installed at the bottom of the fixed frame 1 through a movable shaft. A pair of connecting V-shaped blocks 1 are rotatably installed at the bottom of the pair of support rods 2 through a movable shaft. A shock absorber 1 is rotatably installed between the pair of connecting V-shaped blocks 1 through a movable shaft. One end of the pair of support rods 2 is rotatably installed with a mounting frame 8 through a movable shaft. By providing the fixed frame 1 and the support rods 2, stable support can be provided for the shock absorption system. By using the provided connecting V-shaped block 1, it is convenient for rotational connection. By using the provided shock absorber 1, when in the pitching state, effective shock absorption can be provided.

[0026] Further, a fixed frame 10 is fixedly installed at one end of the mounting frame 8, and a sliding frame 11 is slidably installed at the other end of the mounting frame 8. A chute 9 is opened at one end of the mounting frame 8 close to the sliding frame 11. The sliding frame 11 is slidably matched with the chute 9. By providing the fixed frame 10 and the sliding frame 11, it is convenient to provide support for subsequent installation. The provided chute 9 not only facilitates the sliding of the sliding frame 11, but also can play a certain limiting role on it.

[0027] As a further solution of the present utility model, a shock absorber 2 is rotatably installed between the sliding frame 11 and the fixed frame 10 through a movable shaft. By using the provided shock absorber 2, when the car is in an inclined state, an efficient shock absorption effect can be provided for the device.

[0028] Furthermore, one end of the connecting V-block 1 is rotatably installed with a connecting block 4 through a movable shaft. Both sides of the fixing frame 1 are rotatably installed with connecting V-blocks 2 through movable shafts. The connecting V-block 2 and the connecting block 4 are rotatably connected through a movable shaft. The provided connecting V-block 1, connecting block 4 and connecting V-block 2 can achieve the timely transmission of the motion state, thus ensuring the high efficiency of shock absorption.

[0029] Furthermore, one end of the connecting V-block 2 away from the connecting block 4 is rotatably installed with a connecting rod 6 through a movable shaft. The connecting V-block 2 is used to facilitate the connection of the connecting rod 6, and at the same time, it is convenient to transmit the motion state through the connecting rod 6.

[0030] The specific working method is as follows: The shock absorber 1 and the shock absorber 2 are installed in the fixing frame 0. The connecting rod 6 is connected to the shock absorber 1 through two connecting V-blocks and the connecting block 4, so as to facilitate the transmission of the motion state felt by the connecting rod 6. When the racing car is in a pitching state, the horizontally arranged shock absorber 1 is compressed, while the length of the non-horizontally arranged shock absorber 2 remains unchanged and it is not affected by any force, so as to facilitate driving the shock absorber 1 to perform shock absorption operations. The provided mounting frame 8 is used to facilitate the installation of the shock absorber 2 through the fixing frame 0 and the slidably installed sliding frame 11 provided on the mounting frame 8. The sliding frame 11 and the mounting frame 8 are in sliding fit. When the racing car is in a roll state, the horizontal shock absorber 1 is not affected by force, while the non-horizontally arranged shock absorber 2 is subjected to a tensile force, so that the shock absorber 2 performs shock absorption operations.

[0031] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacements of the above technical features. The matters not covered in the present utility model belong to the common general knowledge of those skilled in the art.
