[0036] The term "plurality" used in the present invention refers to more than two (including two).

[0037] Reference below Figure 1-Figure 2 A shock absorber assembly 100 and a vehicle according to an embodiment of the present invention are described, wherein the shock absorber assembly 100 is used in a vehicle, and the shock absorber assembly 100 is suitable for connecting an axle and a body of the vehicle, or a wheel and a body of the vehicle.

[0038] like Figure 1 and Figure 2 As shown, the shock absorber assembly 100 according to the first embodiment of the utility model includes: a shock absorber 10 and a connecting portion 20.

[0039] Among them, the shock absorber 10 includes a cylinder body 11 and a moving end 12, the moving end 12 is movably arranged in the cylinder body 11, and is at least partially suitable for extending out of the cylinder body 11 at the first end of the cylinder body 11, the moving end 12 is suitable for connecting to a wheel or a bridge, and a connecting part 20 is arranged at the second end of the cylinder body 11. The connecting part 20 includes a bushing 21 and a mounting plate 22. The outer ring of the bushing 21 is connected to the cylinder body 11, and the mounting plate 22 is connected to the inner core of the bushing 21 and is suitable for connecting to the vehicle body.

[0040] Specifically, the cylinder body 11 may include a cylinder body and a base portion arranged at one end of the cylinder body, the base portion is connected to the connecting portion 20 or forms at least a part of the connecting portion 20, the moving end 12 is slidably arranged in the cylinder body, and at least a part of it can extend out of the cylinder body, and the length of the part of the moving end 12 extending out of the cylinder body can be adjusted, and the height difference between the vehicle body and the wheel can be adjusted accordingly, so as to adapt to different road sections and different driving modes by adjusting the height difference, improve the vehicle's passability, and take into account the handling stability.

[0041] Exemplarily, when the moving end 12 is in the minimum extended position, the height difference between the vehicle body and the wheel is small. At this time, the downforce of the vehicle is large, and the vehicle can travel at a higher limit speed. The greater the downforce, the higher the handling stability. When the moving end 12 is in the maximum extended position, the height difference between the vehicle body and the wheel is large. At this time, the ground clearance of the vehicle is large, which can improve the vehicle's passability. At the same time, the pressure medium (such as hydraulic oil) in the cylinder 11 can keep the deviation frequency basically constant, and can also take into account the passability and handling stability to a certain extent.

[0042] It is understandable that during the driving of the vehicle, the wheels will produce vibrations such as shaking relative to the vehicle body, and the base part of the cylinder 11 is connected to the vehicle body, and the moving end 12 is connected to the wheel or the axle. The cylinder 11 and the vehicle body remain relatively stationary, and the moving end 12 can move relative to the cylinder 11. There is continuous pressure medium in the cylinder 11, and the amount and pressure of the pressure medium can be adjusted through external medium pumps, accumulators, pipelines and other structures, so that the shock absorber assembly 100 can effectively absorb the impact of the wheel and improve driving comfort.

[0043] However, in the prior art, the cylinder body is connected to the axle or wheel, and the moving end is connected to the vehicle body. When the moving end is in the maximum extended position, the center point of the moving end will significantly increase the bending moment when subjected to the same force, and the area where the center point of the moving end is located will become a weak area. When the vehicle is subjected to a lateral impact, the moving end has technical problems of insufficient strength and durability, resulting in a decrease in the stability and service life of the shock absorber assembly.

[0044] Based on this, the utility model inverts the shock absorber 10, the cylinder body 11 is connected to the vehicle body through the connecting part 20, and the moving end 12 is connected to the wheel or the axle, that is, the mounting plate 22 is connected to the vehicle body, and the mounting plate 22 is connected to the cylinder body 11 through the bushing 21, that is, the bushing 21 is pressed onto the cylinder body 11, and the inner core of the bushing 21 is connected to the mounting plate 22.

[0045] It should be pointed out that the moving end 12 needs to be provided with a ball head structure to adapt to the bouncing, rotation and vibration of the wheel during the movement of the vehicle. The ball head structure is directly connected to the vehicle body, and it is difficult to ensure the connection strength and stability. The lateral clamping force is relatively small. Based on the structural characteristics of the moving end 12, it is difficult to set the connecting portion 20 at the moving end 12. Setting it at one end of the wheel and the cylinder body 11 with a larger connection area and lower molding difficulty is used to set the connecting portion 20 and connect it to the vehicle body through the connecting portion 20. The lateral clamping force of the shock absorber 10 can be improved. The mounting plate 22 is connected to the cylinder body 11 through the bushing 21, which can reduce the lateral movement of the shock absorber 10 by extending out and eliminating the lateral impact of the center point area of ​​the moving end 12, improve the working stability of the shock absorber assembly 100, and extend the service life of the shock absorber assembly 100.

[0046] According to the shock absorber assembly 100 of the embodiment of the utility model, the cylinder body 11 is connected to the vehicle body through the bushing 21, and the moving end 12 is connected to the wheel, so that the lateral clamping force of the shock absorber 10 can be improved, and the movement of the shock absorber 10 relative to the cylinder body 11 after the shock absorber 10 is subjected to a lateral impact can be eliminated, and the wear of the moving end 12 can be reduced to extend the service life and working stability of the shock absorber assembly 100, and the abnormal working noise of the shock absorber assembly 100 can also be reduced to improve the user experience.

[0047] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the moving end 12 includes: a piston and a piston rod, a working chamber 13 is defined between the piston and the cylinder body 11, and at least a portion of the piston rod is adapted to extend out of the cylinder body 11.

[0048] Specifically, both ends of the cylinder are open, an external thread can be set on the outer periphery of one end of the cylinder, the base part of the cylinder 11 can cooperate with the cylinder thread to seal one end of the cylinder, and the moving end 12 can extend into the cylinder 11 from the other end of the cylinder, and an oil seal can be set between the piston and the inner wall of the cylinder to keep the working chamber 13 sealed.

[0049] It should be pointed out that the cylinder 11 is connected to the vehicle body, and the free end of the piston rod is connected to the wheel or the axle. If the pressure medium liquid level in the working chamber 13 is high, the distance between the wheel and the vehicle body is large, and the ground clearance is large. Correspondingly, the pressure in the working chamber 13 is small or the pressure remains unchanged. If the pressure medium liquid level is small, the distance between the wheel and the vehicle body is small, and the ground clearance is small. In other words, the height of the pressure medium liquid level determines the size of the ground clearance, which is reflected in the passability, and the size of the pressure of the pressure medium in the working chamber 13 is reflected in the hardness of the shock absorber assembly 100.

[0050] Therefore, by adjusting the liquid level of the pressure medium in the working chamber 13 and the pressure in the working chamber 13 , it is possible to achieve both passability and steering stability.

[0051] like Figure 1 As shown, the cylinder body 11 is provided with a medium inlet and outlet 111 , and the medium inlet and outlet 111 is communicated with the working chamber 13 to adjust the medium pressure and the medium liquid level in the working chamber 13 .

[0052] That is to say, the working chamber 13 is connected to the medium pump and the accumulator through the medium inlet and outlet 111. The pressure of the working chamber 13 can be adjusted through the accumulator, and the pressure medium can be supplied to the working chamber 13 or part of the pressure medium can be taken out through the medium pump to adjust the amount of pressure medium in the working chamber 13, thereby realizing the height adjustment of the shock absorber 10.

[0053] In this way, by forming the medium inlet and outlet 111 on the cylinder body 11, the medium inlet and outlet 111 can be formed on the cylinder body or the base part, the position of the medium inlet and outlet 111 is more reasonable, and the pressure and height adjustment are simpler and more convenient.

[0054] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, a mounting portion 112 is disposed on the second end of the cylinder body 11 , the mounting portion 112 has a mounting hole 1121 , and the bushing 21 is disposed in the mounting hole 1121 .

[0055] Specifically, a mounting portion 112 may be formed on the base portion of the cylinder body 11, and the mounting portion 112 may be a mounting ear plate formed on the base portion, and a mounting hole 1121 is provided on the mounting ear plate, and the bushing 21 is press-fitted into the mounting hole 1121. In this way, the connection stability and reliability between the cylinder body 11 and the bushing 21, and between the cylinder body 11 and the mounting plate 22 can be improved.

[0056] Furthermore, the connecting portion 20 further includes a pin shaft 23 , which passes through the inner core and is connected to the mounting plate 22 .

[0057] Specifically, the mounting plate 22 can be constructed as a rectangular plate or a circular plate, and fasteners are provided on the mounting plate 22 to connect with the vehicle body. A through hole can also be opened on the mounting plate 22, and the pin shaft 23 passes through the through hole and is connected to the inner core to achieve the connection and fixation between the mounting plate 22 and the bushing 21, thereby further improving the connection stability and reliability between the shock absorber 10 and the connecting part 20.

[0058] like Figure 1 As shown, further, the mounting plate 22 has a mounting groove 221, at least a portion of the mounting portion 112 extends into the mounting groove 221, and the pin shaft 23 passes through the inner core and the mounting plate 22 in sequence.

[0059] That is to say, a mounting groove 221 is provided on the mounting plate 22, and at least a portion of the mounting portion 112 configured to mount the ear plate can extend into the mounting groove 221, and the pin shaft 23 passes through a through hole opened on the mounting plate 22 and extends into the mounting groove 221, and further passes through an inner core to realize the assembly of the mounting plate 22 and the bushing 21. On the premise of improving the connection stability and reliability between the mounting plate 22 and the bushing 21, in the height direction, the mounting plate 22 and the mounting portion 112 can at least partially overlap, so as to reduce the height dimension occupied by the shock absorber assembly 100, so that the shock absorber assembly 100 occupies less space, has lower layout difficulty, and is more convenient to arrange.

[0060] Combination Figure 1 and Figure 2 As shown, in some embodiments, the medium inlet and outlet 111 is provided at the connecting portion 20 and communicates with the outside through the pipe joint 30 , and a relief portion for avoiding the pipe joint 30 is provided on the mounting plate 22 .

[0061] Specifically, the accumulator and the medium pump are connected to the working chamber 13 through the pipe joint 30, and the avoidance portion is used to avoid the pipe joint 30 and the pipeline, which can reduce the difficulty of arranging the pipe joint 30 and avoid interference between the pipe joint 30 and the mounting plate 22. At the same time, it can also further reduce the space occupied by the shock absorber assembly 100 and reduce the difficulty of arrangement.

[0062] Specifically, the avoidance portion includes an avoidance groove 24, which is located on the side surface of the mounting plate 22 facing the cylinder body 11. The avoidance groove 24 is constructed as an arc-shaped groove to match the arc surface of the pipe joint 30. At the same time, the avoidance portion also includes an avoidance plane 25, which is located on the side of the mounting plate 22 and intersects with the avoidance groove 24. During the installation of the pipe joint 30 and the pipeline, the pipeline can also be avoided through the avoidance plane 25 to avoid interference between the pipeline and the mounting plate 22 during the assembly process, thereby further reducing the difficulty of assembly and improving the convenience of assembly.

[0063] The vehicle according to the embodiment of the second aspect of the utility model comprises: the shock absorber assembly 100 in the above embodiment, and the technical effect thereof is consistent with that of the shock absorber assembly 100, which will not be described in detail here.
