Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, specifically to a valve core for an automotive shock absorber. Background Technology

[0002] During vehicle operation, shock absorbers, as a crucial chassis component, directly affect the vehicle's ride smoothness, handling, and passenger comfort. The core working principle of shock absorbers is to generate damping force through the flow of fluid between different chambers, thereby attenuating vibrations of the vehicle body and suspension.

[0003] Currently, there are many types of damping adjustment structures for automotive shock absorbers on the market, among which the method of adjusting damping force by changing the oil flow rate is the most common. However, existing adjustment structures often suffer from insufficient alignment accuracy between the flow adjustment orifice and the oil outlet orifice. During the movement of the regulating valve core, misalignment of the orifice can easily occur due to unstable guidance or limit failure, resulting in decreased damping force adjustment accuracy and poor stability.

[0004] Based on the above, this utility model proposes an automotive shock absorber valve core, which can effectively solve the above problems. Utility Model Content

[0005] This utility model addresses the shortcomings of the existing technology by providing a valve core for an automotive shock absorber.

[0006] This utility model is achieved through the following technical solution:

[0007] A shock absorber valve core for automobiles includes an adjusting valve core, which is installed inside an adjusting valve sleeve. The adjusting valve core includes a tube body, on the surface of which a plurality of flow regulating holes are evenly distributed at equal intervals along the axial direction, the diameter of which decreases from top to bottom. The surface of the adjusting valve sleeve has an oil outlet hole that communicates with the flow regulating holes. An adjusting block is fixedly connected to the surface of the tube body, and an adjusting groove that mates with the adjusting block is formed on the inner sidewall of the adjusting valve sleeve.

[0008] According to the above technical solution, as a further preferred technical solution, an adjustment knob is fixedly connected to the top of the tube.

[0009] According to the above technical solution, as a further preferred technical solution, the adjusting groove includes a vertical groove extending along the axial direction of the adjusting valve sleeve, one side of the vertical groove is connected to a plurality of rotating grooves evenly distributed at equal intervals, and the end of the rotating groove away from the vertical groove is connected to a limiting groove.

[0010] According to the above technical solution, as a further preferred technical solution, the inner wall of the regulating valve sleeve is provided with a first groove, the first groove is located below the regulating groove, and a first sealing ring is installed inside the first groove.

[0011] According to the above technical solution, as a further preferred technical solution, the outer wall of the regulating valve sleeve is provided with a second groove, and a second sealing ring is installed inside the second groove.

[0012] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0013] This utility model provides an automotive shock absorber valve core. By adjusting the relative movement of the valve core within the adjusting valve sleeve, flow regulating holes of different diameters are made to correspond and connect with the oil outlet hole. The difference in diameter is used to adjust the flow rate of the shock absorber oil, thereby changing the damping force of the shock absorber. Furthermore, the cooperation between the adjusting block and the adjusting groove provides guidance and limit for the movement of the adjusting valve core, ensuring precise alignment between the flow regulating hole and the oil outlet hole, and guaranteeing the stability and reliability of the adjustment.

However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0018] An automotive shock absorber valve core includes an adjusting valve core 1, which is installed inside an adjusting valve sleeve 2. The adjusting valve core 1 includes a tube body 11, on the surface of which a plurality of flow regulating holes 12 are evenly distributed at equal intervals along the axial direction, and the diameter of the flow regulating holes 12 decreases from top to bottom. The surface of the adjusting valve sleeve 2 is provided with an oil outlet hole 21 that cooperates with and communicates with the flow regulating holes 12. An adjusting block 13 is fixedly connected to the surface of the tube body 11, and an adjusting groove 22 that cooperates with and connects to the adjusting block 13 is provided on the inner side wall of the adjusting valve sleeve 2.

[0019] This invention adjusts the relative movement of the regulating valve core 1 within the regulating valve sleeve 2, thereby enabling the flow regulating holes 12 with different orifice diameters to connect with the oil outlet hole 21. The difference in orifice diameter is used to adjust the flow rate of the shock absorber oil, thereby changing the damping force of the shock absorber. Furthermore, the cooperation between the regulating block 13 and the regulating groove 22 provides guidance and limit for the movement of the regulating valve core 1, ensuring precise alignment between the flow regulating hole 12 and the oil outlet hole 21, and guaranteeing the stability and reliability of the adjustment.

[0020] Furthermore, in another embodiment, an adjustment knob 14 is fixedly connected to the top of the tube 11.

[0021] By setting the adjustment knob 14, a convenient force-applying component is provided for the operator, making it easy to manually rotate or axially move the adjustment valve core 1.

[0022] Furthermore, in another embodiment, the adjusting groove 22 includes a vertical groove 221 extending axially along the adjusting valve sleeve 2. One side of the vertical groove 221 is connected to a plurality of rotating grooves 222 that are evenly distributed at equal intervals. The end of the rotating groove 222 away from the vertical groove 221 is connected to a limiting groove 223.

[0023] By setting the adjustment groove 22, the vertical groove 221 of the adjustment groove 22 allows the adjustment block 13 to move axially, which facilitates the adjustment of the valve core 1 to adjust its position up and down; the rotation groove 222 allows the adjustment block (13) to be rotated and positioned. With the rotation groove 222 at different positions, multiple positions of the flow adjustment hole 12 with different orifice sizes and the oil outlet hole 21 can be matched; the limit groove 223 fixes the adjustment block 13 to prevent the valve core from being displaced due to vibration and other factors during operation, and ensures the stability of the damping force after adjustment.

[0024] Furthermore, in another embodiment, the inner wall of the regulating valve sleeve 2 is provided with a first groove 23, the first groove 23 is located below the regulating groove 22, and a first sealing ring 3 is installed inside the first groove 23.

[0025] By setting the first groove 23 and the first sealing ring 3, the gap between the regulating valve core 1 and the regulating valve sleeve 2 can be effectively sealed, thereby improving the sealing performance of the valve core.

[0026] Furthermore, in another embodiment, the outer wall of the regulating valve sleeve 2 is provided with a second groove 24, and a second sealing ring 4 is installed inside the second groove 24.

[0027] By setting the second groove 24 and the second sealing ring 4, the sealing performance between the regulating valve sleeve 2 and other components of the shock absorber is increased.
