[0028] With the improvement of people's living standards, automobile consumers have higher and higher requirements for the quality of automobiles. The shock absorber mounting device is an important part of the vehicle. The shock absorber mounting device mainly provides a mounting point for the vehicle shock absorber, and its performance affects the driving and riding experience of users.

[0029] The external excitation sources received by the vehicle will be transmitted to the entire shock absorber mounting device. However, the shock absorber mounting device integrating the shock absorber and the shock spring has a low stiffness, and there is a great risk of cracking in the structure near the shock absorber mounting position. Therefore, it is necessary to improve the structure of the shock absorber mounting device to increase its stiffness.

[0030] To solve the related technical problems, the present application provides a shock absorber mounting device 1. Refer to Figure 1 , Figure 1 which is a schematic structural diagram of an embodiment of the shock absorber mounting device provided by the present application.

[0031] The shock absorber mounting device 1 includes a vehicle chassis 10, a wheel housing 20 and a strengthening component 30. The vehicle chassis 10 has a first mounting surface; the wheel housing 20 is connected to the vehicle chassis 10. The wheel housing 20 is used to mount the shock absorber. The wheel housing 20 has a second mounting surface. The first mounting surface and the second mounting surface are opposite and arranged at an angle; the strengthening component 30 includes a floor reinforcement plate 330, a wheel housing reinforcement plate 310 and an extension plate 320. The floor reinforcement plate 330 is arranged on the first mounting surface, the wheel housing reinforcement plate 310 is arranged on the second mounting surface, and the extension plate 320 connects the floor reinforcement plate 330 and the wheel housing reinforcement plate 310.

[0032] The wheel housing 20 is connected to one side of the vehicle chassis 10. A shock absorber is installed on the wheel housing 20 to reduce the vibrations received by the vehicle chassis 10 and the wheel housing 20. The floor reinforcement plate 330 is disposed on the first mounting surface on the vehicle chassis 10, thereby strengthening the stiffness of the vehicle chassis 10. Since the wheel housing 20 is relatively thin and has insufficient stiffness, there is a risk of cracking due to long-term exposure to intense vibrations. By providing a wheel housing reinforcement plate 310 thereon, the stiffness of the wheel housing 20 can be strengthened. At the same time, the force transmission path formed by the wheel housing reinforcement plate 310 can enable the force received by the wheel housing 20 to be better transmitted to the shock absorber, thereby reducing the vibrations received by the wheel housing 20. The extension plate 320 connects the wheel housing reinforcement plate 310 and the floor reinforcement plate 330 together, strengthening the connection between the wheel housing 20 and the vehicle chassis 10, making the shock absorber mounting device 1 not easily torsionally deformed, and enabling the force received by the shock absorber mounting device 1 to be better transmitted to the shock absorber through the floor reinforcement plate 330, the extension plate 320, and the wheel housing reinforcement plate 310, thereby enhancing the stiffness of the entire shock absorber mounting device 1.

[0033] The vehicle chassis 10 includes a support beam 110 and a vehicle floor 120. The support beam 110 is connected to the wheel housing 20, and the vehicle floor 120 is supported on the support beam 110. The support beam 110 and the vehicle floor 120 together form the first mounting surface.

[0034] The support beam 110 has a bearing function for the wheel housing 20 and the vehicle floor 120. One side of the support beam 110 is connected to the side of the wheel housing 20 away from the shock absorber, and the other side of the support beam 110 is connected to the vehicle floor 120, thereby connecting the wheel housing 20 and the vehicle chassis 10. The support beam 110 and the vehicle floor 120 together form the first mounting surface. The strengthening assembly 30 is disposed on the first mounting surface and the second mounting surface on the wheel housing 20, thereby strengthening the connection between the wheel housing 20, the support beam 110, and the vehicle floor 120, reducing the risk of detachment between the wheel housing 20 and the vehicle chassis 10, and enhancing the stiffness of the shock absorber mounting device 1.

[0035] See Figure 1 and Figure 2 , Figure 1 is a schematic structural diagram of an embodiment of the shock absorber mounting device provided by the present application. Figure 2 is Figure 1 a partial exploded view of the shock absorber mounting device shown.

[0036] In some embodiments, one end portion of the floor reinforcement plate 330 connected to the extension plate 320 is connected to the support beam 110, and the floor reinforcement plate 330 extends from the vehicle floor 120 to the support beam 110 and is partially connected to the support beam 110. The connection between the extension plate 320 and the support beam 110 can enhance the stiffness of the support beam 110. One end of the extension plate 320 is connected to the floor reinforcement plate 330, and the other end is connected to the wheelhouse reinforcement plate 310, which strengthens the connection strength between the wheelhouse 20 and the support beam 110 and the connection strength between the support beam 110 and the vehicle floor 120.

[0037] The extension plate 320 includes a first connecting portion 321 and a second connecting portion 322 that are bent and connected. The floor reinforcement plate 330 is connected to the extension plate 320 through the first connecting portion 321, and the extension plate 320 is connected to the wheelhouse reinforcement plate 310 through the second connecting portion 322. The first connecting portion 321 is at least partially connected to the support beam 110, and the connection between the floor reinforcement plate 330 and the first connecting portion 321 is used to strengthen the connection strength between the support beam 110 and the vehicle floor 120. The second connecting portion 322 is partially connected to the support beam 110, and the other part extends to the second mounting surface of the wheelhouse 20 to be connected to the wheelhouse reinforcement plate 310, thereby enhancing the connection strength between the wheelhouse 20 and the support beam and the stiffness of the wheelhouse 20.

[0038] A wheelhouse cavity is formed between the wheelhouse reinforcement plate 310 and the wheelhouse 20, an extension cavity is formed between the extension plate 320 and the support beam 110, and a floor cavity is formed between the floor reinforcement plate 330 and the vehicle floor 120. The extension cavity is connected to the wheelhouse cavity and the floor cavity in a through manner.

[0039] The wheelhouse reinforcement plate 310, the extension plate 320 and the floor reinforcement plate 330 are integrally in a U-shape. Therefore, the reinforcement assembly 30 has protrusions and flanges. The flange of the wheelhouse reinforcement plate 310 is connected to the wheelhouse 20, and the protrusion of the wheelhouse reinforcement plate 310 is spaced from the wheelhouse 20 to form a wheelhouse cavity. On the one hand, the protrusion of the wheelhouse reinforcement plate 310 causes the wheelhouse reinforcement plate 310 to extend in different directions, which makes the wheelhouse reinforcement plate 310 not easily twist and deform, and thus the wheelhouse 20 is not easily twist and deformed, and the stiffness of the wheelhouse 20 is improved. On the other hand, when the shock absorber mounting device 1 is stressed, the protrusion of the wheelhouse reinforcement plate 310 can transmit force, reducing the local stress level of the wheelhouse 20, and thus relatively improving the stiffness of the wheelhouse 20. Similarly, the protrusion of the extension plate 320 is spaced from the support beam 110 to form an extension cavity, and the flange of the extension plate 320 is connected to the support beam 110; the protrusion of the floor reinforcement plate 330 is spaced from the vehicle floor 120 to form a floor cavity, and the flange of the floor reinforcement plate 330 is connected to the vehicle floor 120. The protrusions of the extension plate 320 are respectively lapped on the protrusions of the wheelhouse reinforcement plate 310 and the floor reinforcement plate 330. Thus, the protrusions of the reinforcement assembly 30 composed of the wheelhouse reinforcement plate 310, the extension plate 320 and the floor reinforcement plate 330 can assist in transmitting force, enabling vibration to be better transmitted to the shock absorber, and at the same time, the reinforcement assembly 30 makes the shock absorber mounting device 1 not easily twist and deform, thereby improving the stiffness.

[0040] In some embodiments, the floor reinforcement plate 330 is located on the vehicle floor 120 and is spaced from the support beam 110. Considering the vehicle space problem, the floor reinforcement plate 330 is disposed on the vehicle floor 120, and the first connecting portion 321 of the extension plate 320 extends from the support beam 110 to the vehicle floor 120 and is connected to the floor reinforcement plate 330.

[0041] The number of the reinforcement assemblies 30 is at least two, and the at least two reinforcement assemblies 30 are spaced apart. The number of the reinforcement assemblies 30 can be set to multiple, such as two, three, etc., depending on the actual situation. The area of the wheelhouse 20 is large and the stiffness is low. Multiple reinforcement assemblies 30 can be spaced apart so that multiple wheelhouse reinforcement plates 310 reinforce the stiffness of the wheelhouse 20 from different positions and strengthen the connection strength between the wheelhouse 20 and the vehicle chassis 10, so that the shock absorber mounting device 1 is more difficult to twist and deform.

[0042] One end of the floor reinforcement plate 330 of some of the reinforcement assemblies 30 connected to the extension plate 320 is partially connected to the support beam 110, and the floor reinforcement plate 330 of the other part of the reinforcement assemblies 30 is located on the vehicle floor 120 and is spaced from the support beam 110.

[0043] Among them, the floor reinforcement plate 330 of some of the reinforcement components 30 can be set to extend from the vehicle floor 120 to the support beam 110 and be connected to the extension plate 320, and the floor reinforcement plate 330 of the other part of the reinforcement components 30 can be arranged on the vehicle floor 120 at an interval from the support beam 110, and the extension plate 320 extends from the support beam 110 to the vehicle floor 120 and is connected to the floor reinforcement plate 330; alternatively, multiple floor reinforcement plates 330 can be set to extend from the vehicle floor 120 to the support beam 110 or multiple floor reinforcement plates 330 can be arranged on the vehicle floor 120 at an interval from the support beam 110, which can be adjusted according to the actual situation.

[0044] The wheel housing 20 mounts a shock absorber through a shock absorber mounting seat 40 provided thereon. Some of the wheel housing reinforcement plates 310 of some of the reinforcement components 30 are connected to the wheel housing 20 at the corresponding position of the shock absorber mounting seat 40, and the wheel housing reinforcement plates 310 of the other part of the reinforcement components 30 are located on one side of the shock absorber mounting seat 40.

[0045] A shock absorber mounting seat 40 is welded on the wheel housing 20 to facilitate the installation of the shock absorber. One end of the wheel housing reinforcement plate 310 of some of the reinforcement components 30 is arranged corresponding to the position of the shock absorber mounting seat 40, so that some of the wheel housing reinforcement plates 310, the wheel housing 20 and the shock absorber mounting seat 40 are welded together. Thus, while the wheel housing reinforcement plate 310 strengthens the stiffness of the wheel housing 20, the connection between the shock absorber mounting seat 40 and the wheel housing 20 is strengthened; the wheel housing reinforcement plates 310 of the other part of the reinforcement components 30 are located on one side of the position of the shock absorber mounting seat 40, mainly strengthening the stiffness of the remaining part of the wheel housing 20.

[0046] In summary, for the shock absorber mounting device 1 provided in the present application, the setting of the wheel housing reinforcement plate 310 improves the stiffness of the wheel housing 20 and at the same time makes the connection between the shock absorber and the wheel housing 20 more stable. The setting of the floor reinforcement plate 330 improves the stiffness of the vehicle chassis 10. The extension plate 320 connecting the wheel housing reinforcement plate 310 and the floor reinforcement plate 330 makes the connection between the wheel housing 20, the support beam 110 and the vehicle floor 120 more stable. At the same time, the force transmission path formed by the reinforcement component 30 composed of the floor reinforcement plate 330, the extension plate 320 and the wheel housing reinforcement plate 310 helps to transmit the vibration received by the shock absorber mounting device 1 to the shock absorber. Therefore, the stiffness of the shock absorber mounting device 1 in the present application is improved well, and at the same time the NVH (Noise, Vibration, Harshness) performance is also improved.

[0047] The present application also provides a vehicle, which includes the above-mentioned shock absorber mounting device 1. While the stiffness of the shock absorber mounting device 1 is improved, the NVH performance of the whole vehicle is also improved.
