Description

Technical Field

[0001] This utility model relates to the field of automotive damping, and in particular to an adjustable damping automotive shock absorber. Background Technology

[0002] The shock absorber is a core component of a vehicle's suspension system. It typically contains a cylinder filled with hydraulic fluid and a reciprocating piston rod. Vibration energy is dissipated through the damping force generated by the fluid flowing through specific channels, ensuring a smooth ride and stable handling. The damping characteristics of traditional shock absorbers are generally determined during the design phase and cannot be adjusted according to road conditions or driving needs during use, thus limiting their adaptability to complex operating conditions.

[0003] Although some adjustable damping shock absorber structures have emerged in the existing technology, such as those that achieve adjustment through external valve bodies or solenoid valves, they still suffer from problems such as limited adjustment range, complex structure, or reliance on special tools. In particular, most mechanical adjustment schemes only support a limited number of fixed gears and cannot achieve stepless and smooth switching of damping force. This makes it difficult to achieve the best balance of driving experience under different road conditions, limiting their practical application effect and user operation convenience. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable damping automotive shock absorber that allows the damping force to smoothly transition between "soft" and "hard" settings. This enables the shock absorber to quickly adjust its softness and hardness characteristics according to actual road conditions or personal preferences, thereby improving the product's adaptability and user experience.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An adjustable damping automotive shock absorber includes a supporting cylinder, a piston plate slidably connected inside the cylinder, a piston rod fixedly connected to the top of the piston plate, the top of the piston plate being connected to the top of the cylinder via a compression spring, the piston rod penetrating the top of the cylinder externally, a liquid flow port installed on the left side of the cylinder, a connecting seat fixedly connected to the left side of the cylinder, and a limit adjustment component installed inside the connecting seat to block the damping flow.

[0007] Furthermore, the limiting adjustment assembly includes a limiting screw groove located inside the connecting seat, a limiting screw disc is threadedly connected to the inside of the limiting screw groove, a connecting screw is fixedly connected to the outside of the limiting screw disc, the connecting screw is threadedly connected to the outside of the connecting seat, an adjustment disc is fixedly connected to the outside of the connecting screw, and an adjustment switching assembly is installed on the inside of the limiting screw disc.

[0008] Furthermore, the adjustment and switching assembly includes a rotating disk located inside the limiting screw disk, a sealing adjustment plate fixedly connected to the inner side of the rotating disk, the outer side of the sealing adjustment plate being inserted into the inside of the cylinder, and an adjustment groove being provided on the inner right side of the sealing adjustment plate.

[0009] Furthermore, the liquid flow channel includes an oil outlet channel located on the upper left side of the inside of the cylinder, an oil inlet channel located on the lower left side of the inside of the cylinder, and a connecting channel located inside the connecting seat. The oil outlet channel, the connecting channel, and the oil inlet channel are interconnected.

[0010] Furthermore, the opening of the adjustment groove gradually decreases from right to left.

[0011] Furthermore, a limiting ring is fixedly connected to the outside of the rotating disk, and the outside of the limiting ring is rotatably connected to the inside of the limiting screw disk.

[0012] Furthermore, soft rubber rings are fixedly connected to both sides of the limiting screw.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, the user only needs to rotate the adjustment disc clockwise or counterclockwise to precisely control the opening area of ​​the adjustment slot through the linkage between the limiting screw disc and the sealing adjustment plate. This achieves stepless adjustment from "fully open" to "fully closed," allowing for a smooth transition between "soft" and "hard" damping force. Users can quickly adjust the shock absorber's stiffness characteristics according to actual road conditions or personal preference, improving product adaptability and user experience.

Detailed Implementation

[0021] 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.

[0022] Reference Figures 1-3 This utility model provides an embodiment of an adjustable damping automotive shock absorber, comprising a supporting cylinder 1, a piston plate 6 slidably connected inside the cylinder 1, a piston rod 2 fixedly connected to the top of the piston plate 6, the top of the piston plate 6 being connected to the top of the cylinder 1 via a compression spring 5, the piston rod 2 penetrating the top of the cylinder 1 externally, a liquid flow port installed on the left side of the cylinder 1, a connecting seat 3 fixedly connected to the left side of the cylinder 1, a limit adjustment assembly installed inside the connecting seat 3 to block the damping flow, the limit adjustment assembly including a limit screw groove 10 opened inside the connecting seat 3, a limit screw disc 11 threadedly connected inside the limit screw groove 10, a connecting screw rod 9 fixedly connected to the outside of the limit screw disc 11, the connecting screw rod 9 threadedly connected to the outside of the groove of the connecting seat 3, an adjustment disc 4 fixedly connected to the outside of the connecting screw rod 9, and an adjustment switching assembly installed inside the limit screw disc 11, as shown in the reference. Figure 4 The adjustment and switching assembly includes a rotating disk 15 located inside the limiting screw disk 11. A sealing adjustment plate 12 is fixedly connected to the inner side of the rotating disk 15. The outer side of the sealing adjustment plate 12 is inserted into the inside of the cylinder 1. An adjustment groove 17 is opened on the right side of the inside of the sealing adjustment plate 12. The liquid flow channel includes an oil outlet channel 7 opened on the upper left side inside the cylinder 1. An oil inlet channel 8 is opened on the lower left side inside the cylinder 1. A connecting groove 13 is opened inside the connecting seat 3. The oil outlet channel 7, the connecting groove 13 and the oil inlet channel 8 are connected. The opening of the adjustment groove 17 gradually decreases from right to left. A limiting ring 16 is fixedly connected to the outside of the rotating disk 15. The outside of the limiting ring 16 is rotatably connected to the inside of the limiting screw disk 11. Soft rubber rings 14 are fixedly connected to both sides of the limiting screw disk 11.

[0023] When piston rod 2 moves downward due to external impact, piston plate 6 compresses the liquid inside cylinder 1, forcing the liquid to flow from the high-pressure area to the low-pressure area through oil outlet groove 7 and oil inlet groove 8, thereby generating damping force to absorb energy and suppress vibration; at the same time, compression spring 5 provides elastic support, which together enhances the shock absorption effect. If the user rotates adjustment disc 4 counterclockwise, limit screw disc 11 moves outward, driving sealing adjustment plate 12 to move to the left, causing adjustment groove 17 to move to the position of connecting groove 13 and gradually increase its opening area, the liquid flow resistance decreases, the damping force decreases, the shock absorber becomes "softer", and the ride comfort is improved. Conversely, when the adjusting disc 4 is rotated clockwise, the limiting screw disc 11 pushes the sealing adjusting plate 12 to the right, gradually reducing the opening area of ​​the adjusting groove 17 until the sealing adjusting plate 12 completely blocks the connecting groove 13. The fluid flow is obstructed, the damping force rises, and the shock absorber becomes "hard," adapting to rough roads or scenarios with higher handling requirements. During this adjustment process, the soft rubber rings 14 on both sides of the limiting screw disc 11 play a role in stable limiting.

[0024] Working principle: When the piston rod 2 moves downward under external impact, the piston plate 6 compresses the liquid inside the cylinder 1, and the liquid flows through the oil outlet groove 7 and the oil inlet groove 8. The liquid flows from the high-pressure area to the low-pressure area, generating damping force, absorbing energy, and reducing vibration. At the same time, the compression spring 5 provides elastic support and assists in shock absorption. When the user rotates the adjustment disc 4 counterclockwise, the limit screw disc 11 moves outward, the sealing adjustment plate 12 moves to the left, and the adjustment groove 17 moves to the connecting groove 13, with the opening area gradually increasing. The liquid flow resistance decreases, the damping force decreases, and the shock absorber becomes "softer," providing a more comfortable riding experience. When the user rotates the adjustment disc 4 clockwise, the limit screw disc 11 moves inward, pushing the sealing adjustment plate 12 to the right, causing the opening area of ​​the adjustment groove 17 to gradually decrease until the sealing adjustment plate 12 seals the connecting groove 13. When the liquid flows through the adjustment groove, the resistance increases, the damping force increases, and the shock absorber becomes "stiff". It is suitable for rough roads or scenarios that require stronger control. The soft rubber rings 14 on both sides of the limit screw plate 11 ensure the stability of the adjustment limit distance.

[0025] It is worth noting that the pistons, protection, and other foreseeable solutions involved in the above embodiments are all based on existing technologies according to the actual situation, and therefore will not be described in detail in the embodiments of this application.

[0026] 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.
