Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorber technology, and in particular to a multi-stage buffer automotive shock absorber. Background Technology

[0002] Multi-stage shock absorbers are devices used in automotive suspension systems to effectively absorb and attenuate vibrations and impacts generated during vehicle operation through multiple buffering stages. When a vehicle encounters bumps or depressions in the road surface, and the vehicle body moves upward relative to the wheels, the shock absorber enters its compression stroke. At this time, the various buffer elements are compressed sequentially or simultaneously according to the magnitude of the impact force, converting the vehicle's kinetic energy into the elastic potential energy of the elastic elements and the heat energy of the damping elements.

[0003] However, in existing technologies, when shock absorbers malfunction, such as abnormal noise, oil leaks, or poor damping performance, it is necessary to inspect and analyze their internal components to accurately identify the cause of the malfunction. Relying solely on external observation and experience for speculation makes it difficult to accurately pinpoint the fault, potentially leading to misdiagnosis and incorrect repairs, wasting time and resources. Furthermore, it hinders comprehensive and in-depth maintenance of the shock absorber's internal components, preventing the timely detection and resolution of hidden problems and accelerating the overall aging and damage of the shock absorber. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a multi-stage buffer automotive shock absorber. This allows for comprehensive internal cleaning, removing accumulated dust, oil, and impurities to prevent these contaminants from affecting the normal operation of the shock absorber. Simultaneously, it lubricates key components, reducing friction between parts and improving the shock absorber's efficiency and comfort. Since some residual vibration may remain after the first shock absorption, the second shock absorption further filters and buffers these vibrations, significantly reducing the vibration transmitted into the vehicle's cabin. This creates a smoother and more comfortable riding environment for passengers, reducing travel fatigue.

[0005] To achieve the above objectives, a multi-stage buffer type automotive shock absorber is provided, comprising a first sleeve, a second support block disposed inside the first sleeve, a plurality of first outer shells fixedly connected inside the second support block, a first collar fixedly connected to the bottom of the first outer shell, a third spring fixedly connected to the bottom of the first collar, a second fixing block fixedly connected to the bottom of the third spring, a second connecting rod fixedly connected to the bottom of the second fixing block, a rubber block fixedly connected to the bottom of the second connecting rod, a circular block disposed at the bottom of the second support block, a first support block fixedly connected to the bottom of the circular block, a second spring sleeved outside the first support block, two first springs fixedly connected to the outside of the second spring, a sliding column slidably connected inside the first spring, a second sleeve slidably connected to the outside of the sliding column and the rubber block, the inside of the first sleeve and the outside of the second sleeve being slidably connected, a first fixing block fixedly connected to the top of the sliding column, a first rotating shaft rotatably connected inside the first fixing block, a first connecting rod rotatably connected to the outside of the first rotating shaft, a second rotating shaft rotatably connected to the inside of the first connecting rod, and the outside of the second rotating shaft rotatably connected to the inside of the first support block.

[0006] According to the multi-stage buffer type automotive shock absorber, a second sleeve is provided on the outside, and a fourth spring is fixedly connected to the bottom of the second sleeve.

[0007] According to the multi-stage buffer type automotive shock absorber, the fourth spring is fitted with a third sleeve, and the bottom of the first outer shell is provided with a second outer shell.

[0008] Beneficial effects:

[0009] 1. When this device is installed on a car, if the internal mechanism of the first sleeve is damaged, the second support block can be pressed and gently rotated to compress the first outer shell inside. Simultaneously, the third spring at the bottom is compressed, causing the rubber block at the bottom to contact the limiting block at the other end. This ensures accurate alignment of the components during disassembly and reassembly, preventing deviation or damage. This also allows for thorough cleaning of the interior, removing accumulated dust, oil, and impurities, preventing these contaminants from affecting the normal operation of the shock absorber. Furthermore, it lubricates key components, reducing friction between parts and improving the shock absorber's efficiency and comfort.

[0010] 2. During the movement of the second spring outside the first support block, the second spring compresses the two sliding columns outside the first support block, causing them to move in the second sleeve. This causes the first rotating shaft inside the first fixed block at the top of the sliding columns to rotate, thereby moving the first connecting rod outside the first rotating shaft. The first spring sleeved outside the sliding columns restores the sliding columns to their original position under the elastic action of the first spring, thus achieving secondary shock absorption. The first and second sleeves outside the second support block prevent external dust or impurities from entering the mechanism. Since some residual vibration still exists after the first shock absorption, the secondary shock absorption can further filter and buffer these vibrations, significantly reducing the vibration transmitted into the vehicle, creating a smoother and more comfortable riding environment for the driver and passengers, and reducing travel fatigue.

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Reference Figure 1-4 This utility model provides a multi-stage buffer type automotive shock absorber, which includes a first sleeve 1. A second support block 8 is disposed inside the first sleeve 1. A plurality of first outer shells 9 are fixedly connected inside the second support block 8. A first collar 14 is fixedly connected to the bottom of the first outer shell 9. A third spring 15 is fixedly connected to the bottom of the first collar 14. A second fixing block 16 is fixedly connected to the bottom of the third spring 15. A second connecting rod 17 is fixedly connected to the bottom of the second fixing block 16. A rubber block 18 is fixedly connected to the bottom of the second connecting rod 17.

[0021] Specifically: Pressing the second support block 8 and rotating it gently causes the inner first outer shell 9 to be squeezed, while the third spring 15 at the bottom is compressed, thereby causing the rubber block 18 at the bottom to contact the limiting circle 18 at the other end, ensuring that the parts can be accurately aligned during disassembly and reassembly, avoiding deviation or damage.

[0022] A second sleeve 2 is provided on the outside of the rubber block 18, and a fourth spring 20 is fixedly connected to the bottom of the second sleeve 2.

[0023] The fourth spring 20 is fitted with a third sleeve 21, and the bottom of the first outer shell 9 is provided with a second outer shell 22.

[0024] The bottom of the second support block 8 is provided with a circular block 7, and the bottom of the circular block 7 is fixedly connected to the first support block 5.

[0025] Specifically: During the movement of the second spring 6 outside the first support block 5, the second spring 6 compresses, causing the two sliding columns 3 outside the first support block 5 to move in the second sleeve 2, causing the first rotating shaft 1 inside the first fixed block 10 at the top of the sliding column 3 to rotate, thereby causing the first connecting rod 12 outside the first rotating shaft 11 to move, and the first spring 4 sleeved outside the sliding column 3 causes the sliding column 3 to return to its original position under the elastic action of the first spring 4, thereby achieving secondary shock absorption.

[0026] The first support block 5 is fitted with a second spring 6, and two first springs 4 are fixedly connected to the outside of the second spring 6.

[0027] The first spring 4 has a sliding column 3 inside, which ensures that the moving parts move along a predetermined trajectory and improves the accuracy of mechanical movement. The sliding column 3 has a second sleeve 2 outside, and the inside of the first sleeve 1 is slidably connected to the outside of the second sleeve 2.

[0028] The top of the sliding column 3 is fixedly connected to a first fixing block 10, and the inside of the first fixing block 10 is rotatably connected to a first rotating shaft 11.

[0029] The first rotating shaft 11 is externally rotatably connected to the first connecting rod 12, the first connecting rod 12 is internally rotatably connected to the second rotating shaft 13, and the exterior of the second rotating shaft 13 is rotatably connected to the interior of the first support block 5.

[0030] Working principle: When the device is installed on a car, if the mechanism inside the first sleeve 1 is damaged, the second support block 8 can be pressed and rotated gently, causing the first outer shell 9 inside to be squeezed. At the same time, the third spring 15 at the bottom is compressed, thereby driving the rubber block 18 at the bottom to contact the limiting block 18 at the other end. This ensures that the parts can be accurately aligned during disassembly and reassembly, avoiding deviation or damage. This allows for a thorough cleaning of the inside, removing accumulated dust, oil, and impurities, preventing these contaminants from affecting the normal operation of the shock absorber. Simultaneously, it can lubricate key parts, reduce friction between components, and improve the working efficiency and comfort of the shock absorber. During the movement of the second spring 6 outside the first support block 5, the second spring 6 compresses, causing the two sliding columns 3 outside the first support block 5 to move in the second sleeve 2, causing the first rotating shaft 1 inside the first fixed block 10 at the top of the sliding column 3 to rotate, thereby moving the first connecting rod 12 outside the first rotating shaft 11. The first spring 4 sleeved outside the sliding column 3, under the elastic action of the first spring 4, causes the sliding column 3 to return to its original position, thus achieving secondary shock absorption. The first sleeve 1 and the second sleeve 2 outside the second support block 8 can prevent external dust or impurities from entering the mechanism. Thus, after the first shock absorption, there are still some residual vibrations. The secondary shock absorption can further filter and buffer these vibrations, greatly reducing the vibrations transmitted into the vehicle, creating a smoother and more comfortable riding environment for the driver and passengers. The embodiments of this utility model have been described in detail above with reference to the accompanying drawings. However, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model.
