[0037] The term "plurality" used in the present invention refers to more than two (including two).

[0038] Reference below Figure 1-Figure 4 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.

[0039] like Figure 1 , Figure 2 As shown, the shock absorber assembly 100 according to the embodiment of the utility model comprises: a shock absorber 10 and a connecting portion 20 .

[0040] 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 being connected to a wheel or axle, and the connecting part 20 is arranged at the second end of the cylinder body 11. The connecting part 20 includes a connecting rod 21, a rubber sleeve 22 sleeved on the connecting rod 21, and a mounting plate 23. The connecting rod 21 is connected to the cylinder body 11, and the mounting plate 23 is suitable for being connected to the vehicle body.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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 23 is connected to the vehicle body, and a rubber sleeve 22 is arranged between the mounting plate 23 and the connecting rod 21, and the connecting rod 21 is connected to the cylinder body 11.

[0046] 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. This can increase the lateral clamping force of the shock absorber 10 and reduce the movement of the shock absorber 10 after a lateral impact, thereby reducing the lateral impact in the center point area of ​​the moving end 12, improving the working stability of the shock absorber assembly 100, and extending the service life of the shock absorber assembly 100.

[0047] 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 connecting part 20, and the moving end 12 is connected to the wheel or the axle, so that the lateral clamping force of the shock absorber 10 can be improved, and the movement of the moving end 12 relative to the cylinder body 11 after being subjected to a lateral impact can be reduced, and the wear of the moving end 12 can be reduced, so as 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.

[0048] like Figure 2 , Figure 3 and Figure 4As 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] like Figure 3 As shown, in the first embodiment of the present invention, the connecting rod 21 is configured as a solid rod.

[0053] Specifically, the cylinder body 11 may include a base portion and a barrel. The base portion of the cylinder body 11 and the barrel may also be integrally formed, and the connecting rod 21 constructed as a solid rod may be integrally formed with the base portion of the cylinder body 11, or fixed to the base portion by riveting, welding, etc. The solid rod has a higher structural strength, which can further improve the lateral clamping force of the shock absorber 10, thereby improving the lateral impact bearing capacity of the shock absorber assembly 100, improving the stability and reliability of the shock absorber assembly 100, and effectively reducing the wear of the moving end 12, thereby extending the service life of the shock absorber assembly 100.

[0054] Combination Figure 1 and Figure 3 As shown, further, the cylinder body 11 is provided with a medium inlet and outlet 111 (e.g., the medium inlet and outlet 111 is formed on the cylinder body, or formed on the base part, and the base part and the cylinder body can be threaded or integrally formed), and the medium inlet and outlet 111 is connected to the working chamber 13 to adjust the medium pressure and medium liquid level in the working chamber 13.

[0055] 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.

[0056] 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 on the base part, the position of the medium inlet and outlet 111 is more reasonable, the pressure and height adjustment are simpler and more convenient, and the connecting rod 21 can be formed as a solid rod, which effectively improves the ability to resist lateral impact and improves working stability.

[0057] Of course, the structure of the shock absorber assembly 100 of the embodiment of the utility model is not limited thereto. Figure 4 As shown, in the second embodiment, the connecting rod 21 is configured as a hollow rod, and the hollow rod defines a medium channel 211 , and the medium channel 211 is communicated with the working chamber 13 .

[0058] Specifically, a connecting hole is provided on the bottom wall of the base portion, and the hollow rod can be integrally formed with the base portion and connected with the connecting hole, or the hollow rod is threadedly matched with the base portion and connected with the connecting hole.

[0059] In this way, by forming a medium channel 211 on the connecting rod 21, the pressure medium and the liquid level height adjustment can be achieved, and there is no need to form a medium inlet and outlet 111 on the cylinder body 11, so that the sealing of the shock absorber assembly 100 is simpler and more convenient, the overall working stability is higher, and the processing difficulty is lower.

[0060] Combination Figure 2 , Figure 3 as well as Figure 4 As shown, in some embodiments, the rubber sleeve 22 includes: a first sleeve 221, a second sleeve 222, and a sleeve 223, the sleeve 223 is sleeved on the connecting rod 21, the first sleeve 221 and the second sleeve 222 are both sleeved on the sleeve 223, and the outer diameter of the first sleeve 221 is greater than the outer diameter of the second sleeve 222, and the mounting plate 23 is clamped between the first sleeve 221 and the second sleeve 222.

[0061] Specifically, the sleeve 223 is sleeved on the connecting rod 21, and the first sleeve 221 and the second sleeve 222 are arranged in sequence in the axial direction of the connecting rod 21, and a clamping space is defined between the first sleeve 221 and the second sleeve 222. The mounting plate 23 can be clamped in the clamping space and connected to the vehicle body through the mounting plate 23. When the wheel bounces, the bouncing force can be transmitted to the connecting rod 21, and the connecting rod 21 pushes the mounting plate 23 to push against the first sleeve 221 or the second sleeve 222 to achieve buffering of the bouncing force, thereby improving the vibration reduction and buffering effects of the shock absorber 10, and through the setting of the sleeve 223, the connection reliability and stability between the rubber sleeve 22 and the connecting rod 21 are improved, and the structural strength of the connecting part 20 can be further improved.

[0062] In some embodiments, the second sleeve 222 includes: a first section 2221 and a second section 2222, wherein the outer diameter of the first section 2221 is larger than the outer diameter of the second section 2222 to define an accommodating step, and the mounting plate 23 is located on the accommodating step and is spaced apart from the connecting rod 21 in the radial direction of the connecting rod 21.

[0063] Specifically, the radial cross-sections of the first section 2221 and the second section 2222 can be roughly rectangular or trapezoidal, and the second section 2222 is at one end of the first section 2221 adjacent to the mounting plate 23. The outer diameter of the first section 2221 is greater than the outer diameter of the second section 2222, so that a step portion is defined by the end face of the first section 2221 and the side face of the second section 2222, and the step portion is defined as an accommodating step. The end face of the first section 2221 and the end face of the first sleeve 221 and the side face of the second section 2222 define a clamping space, that is, a clamping space is defined between the accommodating step and the end face of the first sleeve 221, and the mounting plate 23 is fixed and limited by the clamping space.

[0064] Therefore, on the one hand, the fixing stability and reliability of the mounting plate 23 can be improved, and on the other hand, contact between the connecting rod 21 and the mounting plate 23 can be avoided, so as to further reduce the wear of the connecting rod 21, extend the service life of the shock absorber assembly 100, and reduce abnormal noise during the operation of the shock absorber assembly 100, thereby improving the user experience.

[0065] like Figure 2 , Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, the connecting portion 20 further includes a first clamping plate 24 and a second clamping plate 25 , and the first clamping plate 24 and the second clamping plate 25 clamp the rubber sleeve 22 and the mounting plate 23 in the axial direction of the connecting rod 21 .

[0066] Specifically, the second clamping plate 25, the first sleeve 221, the mounting plate 23, the second sleeve 222 and the first clamping plate 24 are sequentially passed through the connecting rod 21, and the rubber sleeve 22 and the mounting plate 23 are clamped and fixed by the first clamping plate 24 and the second clamping plate 25, and the free end of the connecting rod 21 is provided with an external thread, and the first clamping plate 24, the rubber sleeve 22, the mounting plate 23 and the second clamping plate 25 are pressed and fixed by fasteners.

[0067] In this way, on the one hand, the axial buffering effect of the shock absorber assembly 100 can be improved by the arrangement of the rubber sleeve 22, the first clamping plate 24 and the second clamping plate 25; on the other hand, the fixing of the mounting plate 23 is more stable, so that the connection stability between the shock absorber assembly 100 and the vehicle body is higher, the lateral clamping force is higher, the stability is higher, and the service life is longer.

[0068] 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 effects thereof are consistent with those of the above shock absorber assembly 100, which will not be described in detail here.

[0069] Other structures and operations of the shock absorber assembly 100 according to the embodiment of the utility model are known to ordinary technicians in the field and will not be described here in detail.
