Description

Technical Field

[0001] The present application relates to the technical field of shock absorbers, and more specifically, to a novel shock absorber assembly. Background Art

[0002] Existing shock absorber assemblies typically consist of a piston, working cylinder, oil reservoir, piston rod, sealing device, valve, and other components. They are primarily installed in a vehicle's suspension system. The movement of the piston within the working cylinder causes oil to flow between different chambers, generating a damping force to suppress vibrations during vehicle operation.

[0003] Existing shock absorber assemblies can improve the driving stability and comfort of vehicles to a certain extent, but existing shock absorbers are all fixed modes and are difficult to adapt to various complex road conditions and driving needs. For example, on rural roads with many potholes or unrepaired construction site sections, it is difficult to effectively absorb strong vibration impacts, causing the vehicle to shake violently. Not only is the ride comfort extremely poor, but it also increases the wear of vehicle parts and reduces the service life of the vehicle. It is also difficult to meet the needs of different drivers. Since different drivers have different driving habits and preferences, this limits the driver's choice of optimizing vehicle performance and reduces the satisfaction with the driving experience.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0028] Reference Figure 1-Figure 5 A novel shock absorber assembly includes a shock absorber body 1, a rod body 2 is provided on one side of the shock absorber body 1, a piston 3 is provided at one end of the rod body 2, the piston 3 is located inside the shock absorber body 1, an adjustment component is provided on one side of the piston 3, and a dustproof component is provided on one side of the shock absorber body 1;

[0029] The adjustment component includes a sleeve 5, a plurality of damping holes 4 are opened inside the piston 3, and a motor 12 is provided on one side of the sleeve 5. The motor 12 is used to drive the sleeve 5 to rotate and adjust the magnitude of the damping force.

[0030] Reference Figure 1-Figure 5A through hole 11 is provided inside the rod body 2, and the motor 12 is fixedly installed inside the through hole 11. The output end of the motor 12 is fixedly connected to the top of the sleeve 5. Two adjustment holes 8 are provided inside the sleeve 5. The two adjustment holes 8 correspond to the corresponding damping holes 4 respectively. Every two damping holes 4 are arranged correspondingly. The inner diameter of the multiple damping holes 4 gradually decreases clockwise along the axis. A hollow plate 9 is provided at the output end of the motor 12, and a limiting ring 10 is provided on one side of the sleeve 5. The limiting ring 10 is rotatably connected to one side of the hollow plate 9. The hollow plate 9 is fixedly connected to the piston 3. A slide groove 6 is provided on the inner wall of the piston 3, and a sliding ring 7 is provided on the outer wall of the sleeve 5. The sliding ring 7 is slidably connected to the slide groove 6. The outer wall of the piston 3 is provided with a seal 13, which is made of elastic material.

[0031] The size of the damping hole 4 can be adjusted by the adjustment component, thereby adjusting the size of the damping force. The specific adjustment method is that since the motor 12 is fixedly installed in the through hole 11 inside the rod body 2, the output end of the motor 12 is fixedly connected to the top of the sleeve 5. When the damping force needs to be adjusted, the motor 12 is started to drive the sleeve 5 to rotate. The two adjustment holes 8 inside the sleeve 5 correspond to the corresponding damping holes 4 respectively. Since the inner diameter of the adjustment hole 8 is larger than the inner diameter of the multiple damping holes 4, and the inner diameter of the multiple damping holes 4 gradually decreases clockwise along the axis, as the sleeve 5 rotates, the adjustment hole 8 gradually coincides with the damping holes 4 of different inner diameters. The sliding ring 7 on the outer wall of the sleeve 5 is slidably connected to the slide groove 6 on the inner wall of the piston 3 to ensure that the sleeve 5 remains stable and does not deviate during the rotation process. At the same time, a hollow plate 9 is provided on the inner wall of the piston 3, and a limit ring 10 on one side of the sleeve 5 is rotatably connected to one side of the hollow plate 9, further limiting and stabilizing the rotation of the sleeve 5.

[0032] When the sleeve 5 rotates so that the adjusting hole 8 coincides with the damping hole 4 with a larger inner diameter, the flow of oil through the damping hole 4 increases and the damping force decreases; when the sleeve 5 rotates so that the adjusting hole 8 coincides with the damping hole 4 with a smaller inner diameter, the flow of oil through the damping hole 4 decreases and the damping force increases. In this way, precise adjustment of the damping force is achieved.

[0033] For example, when driving on a flat road, and the acceleration sensor in the vehicle (this sensor is existing technology and will not be described here) detects that the vehicle is driving on a flat road, in order to improve driving comfort, the driver adjusts it according to his own driving experience and needs (the vehicle can also adjust it according to road conditions), and drives the sleeve 5 to rotate by the driving motor 12, so that the adjustment hole 8 coincides with the damping hole 4 with a larger inner diameter, the flow of oil through the damping hole 4 increases, and the damping force decreases, which better filters out small vibrations on the road. When driving on a rugged mountain road, in order to ensure the stability of the vehicle, the motor 12 controls the sleeve 5 to make the adjustment hole 8 coincide with the damping hole 4 with a smaller inner diameter, the oil flow decreases, the damping force increases, and the violent shaking of the vehicle body is effectively suppressed. When driving at high speed, the position of the sleeve 5 can be appropriately adjusted to increase the damping force to enhance stability; during emergency braking or sharp turns, the sleeve 5 rotates rapidly to completely coincide with the damping hole 4 with a small inner diameter, greatly increasing the damping force, reducing vehicle body tilt, and improving safety and handling.

[0034] By adjusting the components, the damping force can be precisely adjusted according to different driving scenarios, meeting different road conditions and driving requirements, realizing intelligent optimization of the vehicle's vibration reduction performance, and improving the overall driving experience and driving safety.

[0035] Reference Figure 2 、 Figure 5 and Figure 6 The dustproof component includes a fixing plate 14, a card slot 16 is opened on one side of the shock absorber body 1, and one side of the fixing plate 14 is interference fit with the card slot 16. A dustproof scraper 15 is provided on one side of the fixing plate 14, and one side of the dustproof scraper 15 is inclined. One side of the dustproof scraper 15 fits with the outer wall of the rod body 2, and a slider 19 is provided on one side of the fixing plate 14. One side of the slider 19 is inclined. A slot 17 is opened at one end of the fixing plate 14, and an insert block 18 is provided at the other end of the fixing plate 14. The slot 17 and the insert block 18 are plugged into each other, and the slot 17 and the insert block 18 are interference fit.

[0036] The dust scraper 15 of the dustproof component can effectively prevent dust, mud and other impurities from adhering to the rod body 2 and entering the inside of the shock absorber body 1. One side of the dust scraper 15 is inclined and fits the outer wall of the rod body 2. As the rod body 2 moves up and down, the dust scraper 15 can scrape off impurities on the surface of the rod body 2 in time to keep the rod body 2 clean. This greatly reduces the wear and damage of impurities to the internal components of the shock absorber, extends the service life of the shock absorber body 1, ensures that the shock absorber body 1 can always work normally, and maintains stable damping performance.

[0037] The connection method of the slots 17 and the plug blocks 18 at both ends of the fixing plate 14 makes the installation and removal of the dustproof component more convenient and quick. When the dustproof component needs to be maintained or replaced, the operation can be easily performed, thereby improving the maintenance efficiency. At the same time, this connection method also ensures the stability of the dustproof component during vehicle driving, and will not loosen or fall off due to vibration, thereby always providing reliable dustproof protection for the shock absorber body 1.

[0038] Working principle: When the damping force needs to be adjusted, the motor 12 is started to drive the sleeve 5 to rotate. The two adjustment holes 8 inside the sleeve 5 correspond to the corresponding damping holes 4 respectively. Since the inner diameter of the adjustment hole 8 is larger than the inner diameter of the multiple damping holes 4, and the inner diameter of the multiple damping holes 4 gradually decreases clockwise along the axis, as the sleeve 5 rotates, the adjustment hole 8 gradually overlaps with the damping holes 4 with different inner diameters. The sliding ring 7 on the outer wall of the sleeve 5 is slidably connected with the slide groove 6 on the inner wall of the piston 3 to ensure that the sleeve 5 remains stable and does not deviate during the rotation process. At the same time, a hollow plate 9 is provided on the inner wall of the piston 3, and a limiting ring 10 on one side of the sleeve 5 is rotatably connected to one side of the hollow plate 9, which further limits and stabilizes the rotation of the sleeve 5.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
