Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorption technology, and in particular to an adjustable pressure relief cover for automotive shock absorbers. Background Technology

[0002] Automotive damping technology is a core technology for improving vehicle ride comfort and stability. Through the coordinated action of components such as shock absorbers and springs, it absorbs the vibration energy generated by road bumps and suppresses vehicle body resonance. Its core principle is to utilize the combination of damping force and elastic elements to convert kinetic energy into heat energy, thereby reducing the impact of vibration on the vehicle body and passengers. Widely used in various types of motor vehicles, it is one of the key technologies for ensuring driving comfort and safety.

[0003] The shock absorber decompression cap is a crucial component of this technology system. Installed on top of the shock absorber, it dynamically alters the damping characteristics by adjusting the flow resistance of internal hydraulic oil or gas. It fulfills the core requirement of "on-demand adjustment" in shock absorption technology, adjusting the decompression threshold according to road conditions or load changes. This allows the shock absorber to flexibly switch between "soft" and "hard" settings, further optimizing the damping effect and making it a key component for achieving dynamic adaptation of damping performance.

[0004] However, in the existing technology, the pressure adjustment structure of some shock absorbers is fixed, which makes it impossible to adjust the spring preload. The design does not take into account the different requirements of different vehicles for the shock absorber pressure threshold, making it difficult for the same good shock absorber to be adapted to different models. This makes it impossible to reuse second-hand good shock absorbers, which not only increases the cost of purchasing parts during maintenance, but also causes idle and wasteful resources.

[0005] Therefore, an adjustable pressure relief cover for automotive shock absorbers is proposed to address the above problems. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an adjustable pressure relief cover for automotive shock absorbers, aiming to improve the problem that some shock absorbers in the prior art have fixed pressure threshold adjustment structures, which cannot adjust the spring preload and are difficult to adapt to the pressure requirements of different vehicles. This results in used, intact shock absorbers being unable to be reused, increasing procurement costs and wasting resources.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An adjustable pressure relief cover for an automotive shock absorber includes a cover body, a threaded ring rotatably connected to the inner wall of the cover body, a knob fixedly connected to the top end of the threaded ring, a threaded post threadedly connected to the inner wall of the threaded ring, and a hydraulic component fixedly connected to the bottom end of the threaded post.

[0009] As a further description of the above technical solution:

[0010] The threaded ring is externally fixedly connected to a limiting ring that rotates on the inner wall of the cover.

[0011] As a further description of the above technical solution:

[0012] The hydraulic assembly includes a push rod fixedly connected to the bottom end of a threaded column, and a hydraulic support is provided on the outside of the push rod;

[0013] As a further description of the above technical solution:

[0014] The top of the hydraulic support is fixedly connected to a hydraulic base shell, and the inner wall of the hydraulic base shell and the bottom of the cover are both fixedly connected to an isolation plate.

[0015] As a further description of the above technical solution:

[0016] A mounting block is fixedly connected to the right side of the hydraulic support, and the mounting block is fixedly connected to the shock absorber mounting interface by screws.

[0017] As a further description of the above technical solution:

[0018] A sealing sleeve is fixedly connected to one of the adjacent sides of the two isolation plates, and the sealing sleeve is fitted outside the threaded column. A spring is also fixedly connected to one of the adjacent sides of the two isolation plates.

[0019] As a further description of the above technical solution:

[0020] The knob has a hollow structure, and the outer wall of the knob is provided with anti-slip texture;

[0021] As a further description of the above technical solution:

[0022] The edge of the cover has multiple screw mounting holes evenly distributed, and the inner wall of the mounting holes is provided with metal threaded nails.

[0023] This utility model has the following beneficial effects:

[0024] In this invention, rotating the knob can drive the threaded ring and threaded column to move up and down, thereby compressing the spring and adjusting the spring preload to change the shock absorber pressure threshold. This design allows the same intact shock absorber to be reused by adjusting it to meet the pressure threshold requirements of different vehicles, thereby reducing maintenance costs and minimizing resource waste.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 4 This utility model provides an embodiment of an adjustable pressure-reducing cover for an automotive shock absorber, comprising a cover body 1, which is the main body of the pressure-reducing cover; the edge of the cover body 1 is evenly distributed with multiple screw mounting holes for fixing and installing with the shock absorber; the inner wall of the mounting holes is provided with a metal threaded sleeve to enhance the connection strength of the mounting holes and ensure stable installation; a threaded ring 2 is rotatably connected to the inner wall of the cover body 1 for cooperating with a threaded post 5 to achieve transmission; a limiting ring 3 that rotates on the inner wall of the cover body 1 is fixedly connected to the outside of the threaded ring 2 to ensure that the threaded ring 2 rotates stably within the cover body 1 without axial movement.

[0033] A knob 4 is fixedly connected to the top of the threaded ring 2, which is used to drive the threaded ring 2 to rotate for adjustment. The knob 4 has a hollow structure. When adjusting the pressure, the threaded column 5 will rise. The hollow design ensures that the adjustment is not affected by the threaded column 5. The outer wall of the knob 4 is provided with anti-slip texture to increase friction. It is also equipped with two small handles for easy gripping and rotation by the operator. The inner wall of the threaded ring 2 is threadedly connected to the threaded column 5. The preload is adjusted by compressing the spring 12 through axial lifting and lowering movement. A hydraulic component is fixedly connected to the bottom of the threaded column 5, which is used to transmit pressure to change the internal pressure of the shock absorber. The hydraulic component includes a push rod 6 fixedly connected to the bottom of the threaded column 5, which moves into the hydraulic support 7 as the threaded column 5 rises and falls. The hydraulic support 7 is set outside the push rod 6 and accommodates the movement of the push rod 6 to cooperate with the adjustment of pressure.

[0034] The top of the hydraulic strut 7 is fixedly connected to a hydraulic base shell 8, providing an installation base for the hydraulic components. Isolation plates 9 are fixedly connected to both the inner wall of the hydraulic base shell 8 and the bottom of the cover 1, forming a sealed space and providing installation positions for the sealing sleeve 11 and the spring 12. An installation block 10 is fixedly connected to the right side of the hydraulic strut 7 for connection to the shock absorber mounting interface. The installation block 10 is fixedly connected to the shock absorber mounting interface with screws to ensure the stability of the overall structure during operation. A sealing sleeve 11 is fixedly connected to the adjacent side of the two isolation plates 9 to ensure the sealing performance between the isolation plates 9. The sealing sleeve 11 is fitted over the outside of the threaded column 5 to prevent hydraulic oil leakage during the lifting and lowering of the threaded column 5. A spring 12 is also fixedly connected to the adjacent side of the two isolation plates 9, which, by being squeezed, changes the compression amount to adjust the preload, thereby changing the shock absorber pressure threshold to adapt to different vehicle requirements.

[0035] Working principle: The cover 1 is fixedly installed with the shock absorber through the screw mounting holes and metal threaded sleeve on the edge of the cover 1; when adjustment is required, the hollow knob 4 with anti-slip texture is rotated, and the knob 4 drives the threaded ring 2 to rotate synchronously. The limiting ring 3 on the outside of the threaded ring 2 ensures that it rotates stably on the inner wall of the cover 1 without axial movement; since the threaded ring 2 and the threaded column 5 are threadedly connected, the rotation of the threaded ring 2 will be converted into the axial lifting and lowering movement of the threaded column 5; when the threaded column 5 descends, it pushes the top rod 6 to move into the hydraulic support 7, and at the same time squeezes the spring 12. By changing the compression of the spring 12, the preload is adjusted, thereby changing the pressure threshold inside the hydraulic component.

[0036] During the lifting and lowering of the threaded column 5, the sealing sleeve 11 ensures the sealing performance between the isolation plates 9 to prevent hydraulic oil leakage; the hydraulic base 8 provides an installation base for the hydraulic components, and the mounting block 10 is fixed to the shock absorber mounting interface by screws to ensure the stability of the overall structure during operation; this design allows the same shock absorber to change the preload by adjusting the knob 4 to adapt to the pressure threshold requirements of different vehicles and realize the secondary use of intact shock absorbers.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
