For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0026] In this embodiment, in the first aspect, the present invention discloses a vehicle shock absorber valve plate, including a valve plate body 100, a mounting hole 200 is provided on the valve plate body 100, and the mounting hole 200 is arranged on one side of the center position of the valve plate body 100, and an oil storage tank 300 surrounding the mounting hole 200 is provided on one surface of the valve plate body 100, and a first liquid hole 400 and a second liquid hole 500 are provided on the valve plate body 100 and are located on one side of the mounting hole 200.

[0027] Through the above description, the present invention discloses a vehicle shock absorber valve plate, which is used in a hydraulic vehicle shock absorber, and includes a valve plate body 100. The mounting hole 200 opened on the valve plate body 100 deviates from the center of the valve plate body 100, that is, a mounting hole 200 eccentric to the valve plate body 100 is opened on the valve plate body 100, which can optimize the oil flow path, enhance the response sensitivity of the valve plate, and reduce the wear of the valve plate.

[0028] When the oil passes through the valve, due to the eccentricity of the mounting hole 200, the oil will enter or flow out of the valve area in an asymmetric manner. This asymmetric flow path can cause the oil to generate more complex vortices and turbulence around the valve. In the compression stroke, when the oil passes through the compression valve, the eccentric mounting hole 200 causes the oil to generate lateral force when flowing through the valve, which helps to break the laminar flow state that the oil may originally appear, allowing the oil to be more fully mixed and dispersed, and the flow rate of the oil at different pressures can be more accurately controlled. During the driving process of the vehicle, the road conditions are complex and changeable. This precise throttling control can better adapt to impacts of different intensities, thereby providing a more appropriate damping force, so that the valve plate can more accurately control the flow rate of the oil at different pressures;

[0029] In addition, the eccentrically arranged mounting hole 200 can change the stress condition of the valve plate. When the oil pressure acts on the valve plate, the valve plate will generate a torque due to the eccentricity of the mounting hole 200. This torque makes it easier for the valve plate to open or close under a smaller pressure difference. For example, during the extension stroke, when the oil pressure changes slightly, the torque acting on the valve plate with the eccentric mounting hole 200 will cause the extension valve to open or close faster, thereby enabling the shock absorber to respond more quickly to the rebound action of the wheel; and can improve the driving comfort and handling stability of the vehicle.

[0030] When the vehicle is traveling at high speed, the road surface experiences frequent minor bumps and vibrations. The valve plate with the mounting hole 200 having an eccentric structure can quickly adjust the damping force, effectively filter out these vibrations, and keep the vehicle body stable. Under conditions such as vehicle steering or braking, it can also quickly respond to changes in the vehicle body posture and provide timely support and damping.

[0031] In one or more possible embodiments of the present invention, the valve plate body 100 is a circular structure, and an arc-shaped notch 110 is provided on the outer edge of the valve plate body 100. The outer edge of the valve plate body 100 is also provided with an arc-shaped protrusion 120 located on one side of the arc-shaped notch 110, which can reduce the weight of the valve plate body 100, facilitate processing, and reduce the difficulty of installing the equipment.

[0032] In one or more possible embodiments of the present invention, the oil storage tank 300 includes a first part 310 and a second part 320, the first part 310 is a circular groove surrounding the mounting hole 200, the second part 320 is communicated with the first part 310, the second part 320 is a rectangular structure, one side of the second part 320 is tangent to the first part 310, and the width of the second part 320 is smaller than the diameter of the first part 310; by setting the oil storage tank 300, it is possible to improve the stability of oil supply, optimize oil flow characteristics, reduce the occurrence of cavitation, and extend the service life of the valve plate.

[0033] The shock absorber valve plate disclosed in the present invention is used in a hydraulic automobile shock absorber. An oil storage tank 300 is opened on the valve plate body 100 around the mounting hole 200 of the eccentric structure to provide a temporary storage space for the oil. When the flow of the oil in the valve area fluctuates instantaneously, such as when the vehicle frequently passes through a bumpy road during driving, the pressure and flow of the oil change rapidly. The oil storage tank 300 can store a certain amount of oil, and when the oil flow demand suddenly increases, it can be replenished in time to ensure the stability of the oil supply.

[0034] When the oil passes through the area around the eccentric mounting hole 200, part of it will enter the oil storage tank 300 and then flow out. This flow mode can make the oil form a more complex circulation flow in the local area, which is conducive to the mixing and temperature balance of the oil.

[0035] When the oil flows rapidly in the shock absorber, cavitation may occur due to pressure changes. The oil reservoir 300 can act as a buffer area to reduce the degree of rapid changes in oil pressure. When the oil pressure drops, the oil in the oil reservoir 300 can be replenished in time to reduce the formation of local vacuum areas, thereby effectively preventing the occurrence of cavitation. This is very important for maintaining the stability of the performance of the shock absorber and extending its service life.

[0036] The oil storage tank 300 can disperse the impact force of the oil on the valve plate. In the absence of the oil storage tank 300, the oil directly impacts the valve plate, especially near the eccentrically arranged mounting hole 200. Due to the asymmetry of the oil flow, the valve plate may be locally subjected to excessive force. The oil storage tank 300 can guide the oil to enter the tank first, and then act on the valve plate smoothly, so that the impact force on the valve plate is more uniform. This helps to reduce the wear and fatigue damage of the valve plate. The extended service life of the valve plate can reduce the number of failures and repairs of the shock absorber due to valve plate damage, thereby reducing the maintenance cost of the car.

[0037] In one or more possible embodiments of the present invention, the first liquid passage hole 400 and the second liquid passage hole 500 are symmetrically arranged with respect to the center line of the valve plate body 100 .

[0038] In one or more possible embodiments of the present invention, the first liquid hole 400 includes a first edge 410 that is inclined, and the two ends of the first edge 410 are respectively connected to a second edge 420 and a third edge 430 that are vertically arranged, the other end of the second edge 420 is connected to a fourth edge 440 through an arc 450, and the other end of the fourth edge 440 is cooperatively connected to the third edge 430, the fourth edge 440 is arranged parallel to the first edge 410, and the first edge 410 and the second edge 420 and the third edge 430 are connected at rounded corners, and the third edge 430 and the fourth edge 440 are connected at rounded corners.

[0039] Through the above arrangement, the shock absorber valve plate disclosed in the present invention can improve the balance of oil flow distribution, enhance the response speed and stability of the shock absorber, and reduce oil flow noise.

[0040] The shock absorber valve plate disclosed in the present invention is used in a hydraulic automobile shock absorber. When the oil passes through the valve plate, the two groups of liquid holes symmetrically arranged above the eccentrically arranged mounting hole 200 can make the oil more evenly distributed to different directions. Since the mounting hole 200 is eccentrically arranged relative to the valve plate body 100, the oil flow path itself is asymmetric, and the two groups of liquid holes can adjust this asymmetric oil flow. For example, in the compression stroke, the oil flows from the lower cavity of the piston to the upper cavity. The two groups of liquid holes can evenly distribute the oil to different areas of the upper cavity to avoid excessive concentration of the oil in a certain area, so that the oil exchange between the upper and lower cavities of the piston is smoother and more stable; this balanced oil distribution helps to optimize the damping characteristics of the shock absorber, and can ensure that the shock absorber provides a stable and appropriate damping force under different road conditions. Because the oil flow is evenly distributed, there will be no sudden change in the damping force caused by the concentrated flow of oil during the driving of the vehicle, thereby improving the comfort and controllability of the vehicle.

[0041] The two sets of fluid holes can work at the same time, and they can quickly guide the fluid through the valve plate when the oil pressure changes. When the vehicle encounters a sudden road impact, such as a large pothole when driving at high speed, the oil needs to pass through the valve plate quickly to adjust the damping force. At this time, the two sets of fluid holes are like two parallel channels that can allow the oil to pass through at the same time, speeding up the flow of the oil, so that the shock absorber can respond to the impact more quickly; moreover, the symmetrical arrangement of the fluid holes can also increase the stability of the shock absorber during operation. When the shock absorber works for a long time or is frequently vibrated, the symmetrical structure helps to balance the pressure and flow of the oil, and prevent the valve plate from being deflected or unstable due to excessive or insufficient pressure in the fluid hole on one side. This is very important for maintaining the normal working state of the shock absorber and extending its service life.

[0042] When the oil passes through the valve plate, the combination design of the eccentrically arranged mounting hole 200 and the two groups of liquid holes can make the flow of the oil more orderly. When the oil passes through the liquid holes, the two symmetrical groups of channels can reduce the turbulence and vortexes in the flow of the oil. Turbulence and vortexes are one of the main reasons for flow noise. During vehicle driving, especially in a quiet environment or when the vehicle is driving at a lower speed, this design can effectively reduce the noise generated when the oil flows in the valve area, thereby improving the quietness of the vehicle interior and providing passengers with a more comfortable driving environment.
