Description

Technical Field

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

[0002] The shock absorber is a core component of the car suspension system. Its main function is to suppress the oscillation when the spring absorbs the shock and the impact from the road surface. By converting the vibration energy generated during vehicle operation into heat energy and other forms of energy, it ensures the smoothness, stability and ride comfort of the vehicle. At the same time, it reduces the wear and damage to various parts of the vehicle caused by vibration and extends the service life of the vehicle.

[0003] However, the guiding performance of the existing automotive shock absorber's buffer structure is inadequate. During operation, components are prone to lateral displacement or swaying. This not only leads to unstable buffering effect and affects the vehicle's ride stability, but also exacerbates friction and wear between components, shortens the shock absorber's lifespan, and increases vehicle maintenance costs. Furthermore, the buffer structure of existing automotive shock absorbers is directly exposed to the external environment. During vehicle operation, hard objects such as gravel and metal fragments on the road, as well as debris splashed during driving, will directly contact the core components. Direct collisions between hard objects and components can easily cause dents, scratches, or even deformation of the component surface. Splashed debris can easily get stuck between components, affecting their normal movement, compromising the fit between components, and causing obstructed movement. Over time, this will seriously affect the performance stability of the shock absorber, and may even lead to shock absorber failure, posing a significant safety hazard to vehicle operation. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model embodiment is to provide a buffer device for an automobile shock absorber, which can solve the technical problems of poor guiding performance of the buffer structure leading to easy displacement and shaking of components, unstable buffering effect and aggravated wear, and the core components being easily damaged by direct contact with foreign objects due to the exposed buffer structure.

[0005] In a first aspect, this utility model provides a buffer device for an automobile shock absorber, comprising: a fixed base, a first connecting bracket, a protective component, a buffer component, a second connecting bracket, and a connecting hole; The protective assembly includes a base, a protective shell, and a T-shaped guide groove; The lower end of the base is fixedly connected to the upper end of the fixed seat, and the lower end of the protective shell is fixedly connected to the upper end of the base. Several T-shaped guide grooves are provided, and all of the T-shaped guide grooves are opened on the inner wall surface of the protective shell. The buffer assembly includes a mounting base, a damper, a spring, a top block, and a T-shaped guide block; The mounting base is fixedly sleeved inside the lower part of the protective shell. The lower end of the damper and the lower end of the spring are both fixedly connected to the upper end of the mounting base. The lower end of the top block is fixedly connected to the upper end of the damper and the upper end of the spring. Several T-shaped guide blocks are provided, and the ends of the several T-shaped guide blocks near the center of the top block are all fixedly connected to the outer surface of the top block. Several top blocks are movably fitted inside the protective shell, and several T-shaped guide blocks are movably fitted inside corresponding T-shaped guide grooves.

[0006] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following: In this embodiment of the invention, the device is fixed between the vehicle suspension and the vehicle body through the connecting holes on the first and second connecting brackets. The fixed seat supports the protective component and the buffer component. The top block is initially positioned inside the protective shell, and the T-shaped guide block and the T-shaped guide groove are initially engaged. The spring is naturally extended, and the damper is not deformed. When the vehicle encounters bumps or obstacles, the impact force is transmitted through the suspension to the second connecting bracket and then to the top block. The top block drives the T-shaped guide block to slide down along the T-shaped guide groove. The spring is compressed to absorb energy, and the damper contracts to consume energy. The protective component blocks impurities and protects the internal components. After the impact force dissipates, the spring extends and pushes the top block upward. The T-shaped guide block slides upward along the T-shaped guide groove to reset, and the damper extends to buffer and prevent rebound. Finally, the device returns to its initial state. The engagement of the T-shaped guide block and the T-shaped guide groove ensures the stability of the top block's movement, reduces wear, and extends its lifespan. The spring and the damper work together to improve the buffering effect, enhance driving stability and ride comfort, and the protective component effectively blocks impurities to ensure reliability. The layout of the damper and the spring saves space and avoids mutual interference, ensuring the coordinated work of all components. Attached Figure Description

[0019] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following: In this embodiment of the invention, the device is fixed between the vehicle suspension and the vehicle body via the connecting holes 6 on the first connecting bracket 2 and the second connecting bracket 5. The fixing seat 1 supports the protective component 3 and the buffer component 4. The top block 44 is initially positioned inside the protective shell 32. The T-shaped guide block 45 is initially engaged with the T-shaped guide groove 33. The spring 43 is naturally extended, and the damper 42 is not deformed.

[0021] In this embodiment of the utility model, the connection positions of each component are clearly defined to ensure the overall structure of the device is stable and facilitates installation and force transmission.

[0022] In one possible implementation, a plurality of T-shaped guide grooves 33 are arranged in a circular array around the center of the protective shell 32.

[0023] In this embodiment of the invention, the T-shaped guide grooves 33 distributed in a ring array ensure that the top block 44 is subjected to uniform force, moves more smoothly, and reduces local wear.

[0024] In one possible implementation, the damper 42 is located inside the spring 43 and has a gap with the inner wall surface of the spring 43, and the spring 43 has a gap with the inner wall surface of the protective shell 32.
