Description
Technical Field
[0001] This utility model relates to the field of shock absorber top cover technology, specifically a shock absorber buffer top cover. Background Technology
[0002] Shock absorbers play a crucial role in the operation of off-road vehicles such as ATVs and ordinary cars. As a key component, the shock absorber cover has undergone many stages of technological development. In the early days, traditional shock absorber covers were simple in design and mostly made of a single material, usually metal. While this structure could provide basic cushioning for bumps on ordinary roads, its drawbacks became apparent when faced with the frequent high-speed driving of ATVs on rugged sandy terrain or the severe impacts of cars passing over potholes at high speeds. On the one hand, the metal cover was rigid but lacked toughness, and could not effectively absorb the high-intensity impact force generated instantly, which could easily lead to premature damage to the internal parts of the shock absorber, such as wear of oil seals and bending of piston rods, greatly shortening the service life of the shock absorber. On the other hand, its cushioning performance was limited and could not adapt to the complex force changes brought about by impacts of different frequencies and intensities, resulting in a poor driving experience. Vibrations and bumps were strongly transmitted to the interior of the vehicle, which not only affected comfort but could also cause other parts of the vehicle to loosen over time.
[0003] With the improvement of vehicle performance and the increasing sophistication of driving and riding needs, the market urgently calls for a shock absorber buffer cover technology that can provide excellent cushioning under complex working conditions, is durable, and can adapt to diverse impacts, in order to meet the pursuit of stability, comfort and durability of various vehicles such as ATVs and automobiles. To this end, we have proposed a shock absorber buffer cover. Utility Model Content

[0014] (III) Beneficial Effects
[0015] Compared with the prior art, the advantages of this utility model are:
[0016] A shock absorber buffer cover is provided, which has the following beneficial effects:
[0017] 1. Enhanced cushioning performance: By setting up a multi-layered cushioning structure, such as connecting cushioning pads, top cover cushioning springs, and internal protective springs, it can effectively absorb impact forces of different intensities and frequencies. When the vehicle encounters potholes or rough roads during driving, the connecting cushioning pads can first buffer some of the vibration, and then the top cover cushioning springs further absorb the remaining impact force. The multi-layered cushioning structure works together to greatly improve the overall cushioning effect. Compared with the traditional single-material top cover, it can better cope with complex road conditions, significantly improve the vehicle driving experience, and reduce vibration and bumps inside the vehicle.
[0018] 2. Protecting internal shock absorber components: When subjected to severe impact, the internal protective spring provides additional protection for the top cover buffer assembly, preventing the impact force from being directly transmitted to the internal components of the shock absorber. This reduces the risk of damage such as oil seal wear and piston rod bending, and extends the service life of the shock absorber. For example, when a vehicle passes over a large pothole at high speed, the internal protective spring can effectively alleviate the instantaneous high-intensity impact force, protect the precision components inside the shock absorber, and reduce maintenance and replacement costs.
[0019] 3. Easy to install and fix: The buffer fixing connection component and the top cover connection component are reasonably designed. Through the shock absorber connecting screw, the top cover connecting screw, and the corresponding threaded holes and connecting holes, a stable and convenient connection between the buffer top cover and the shock absorber is achieved. During the installation process, simply align the screws with the corresponding holes for installation. The operation is simple, improves the installation efficiency, and also ensures the stability of the top cover during use, avoiding loosening that may affect the shock absorption effect.

[0033] Structural Description:
[0034] Damper top support rod 1: As the basic part connecting the entire device with the upper part of the shock absorber, its bottom inner side is designed to slide with the damper bottom support rod 3, providing guidance and support for relative movement during the damping process. The top outer side is used to fix the shock absorber buffer spring 2. At the same time, the top surface is provided with equidistantly distributed connecting threaded holes 9. These threaded holes are used to cooperate with the shock absorber connecting screws 8 in the buffer fixing connection assembly to achieve a stable connection between the components and ensure that the entire top cover structure can be reliably installed on the shock absorber.
[0035] Shock absorber spring 2: This is a key component of the basic shock absorption structure. Its two ends are fixed to the top outer side of the top support rod 1 of the damper and the bottom surface of the bottom support rod 3 of the damper, respectively. When the vehicle encounters vibration or impact during driving, the shock absorber spring 2 will undergo elastic deformation. It absorbs and disperses energy through compression and extension, playing a preliminary role in buffering vibration and effectively reducing the impact force on the vehicle. It is one of the core components to ensure the shock absorption effect.
[0036] The bottom support rod 3 of the damper is slidably connected to the bottom inner side of the top support rod 1 of the damper. During the damping process, it provides a track for relative movement of the top support rod 1, so that the two can slide relative to each other flexibly according to the vibration. At the same time, it is also the support base of the damper buffer spring 2, ensuring that the spring can stably play a buffering role when working and maintain the structural stability of the entire damping system.
[0037] Connecting buffer pad 4: Located on the top surface of the top support rod 1 of the damper, the material usually has good elasticity and buffering performance. It is directly fixedly connected to the top support rod 1 of the damper. During the vibration transmission process, it first buffers the vibration from the damper, reduces the transmission of rigid impact, protects the components above from excessive vibration, and provides a stable installation base for the top support platform 5.
[0038] Top support platform 5: Fixed on the top surface of the connecting buffer pad 4. Both the top surface of the top support platform 5 and the top surface of the connecting buffer pad 4 are provided with equally spaced connecting holes 10, which are concentrically aligned with the connecting threaded holes 9 of the top support rod 1 of the damper. On the one hand, the top support platform 5 is stably connected to the top support rod 1 of the damper through the shock absorber connecting screw 8. On the other hand, the buffer groove opened on its top provides space for the installation and sliding of the internal buffer platform 13 in the top cover buffer assembly. It plays a key connecting and supporting role in the whole structure.
[0039] Shock absorber connecting screw 8: It passes through the connecting hole 10 connecting the buffer pad 4 and the top support platform 5, and is threaded to the connecting threaded hole 9 of the damper top support rod 1. It tightly fixes the various parts of the buffer fixing connection assembly together, ensuring that the entire assembly remains stable in the vibration environment, while allowing the connecting buffer pad 4 and the top support platform 5 to slide relative to each other within a certain range, thereby enhancing the buffering effect.
[0040] Internal buffer platform 13: It slides in the buffer groove at the top of the top support platform 5. Its shape and size are adapted to the buffer groove to ensure smooth sliding. When the vehicle is vibrated, the internal buffer platform 13 will move up and down in the buffer groove to initially buffer the vibration. The sliding groove opened at its top provides installation and movement space for the top cover buffer spring 14 and the top cover connecting plate 16, further dispersing and absorbing vibration energy.
[0041] Top cover buffer spring 14: Fixed in the sliding groove at the top of the internal buffer platform 13, one end is connected to the bottom of the sliding groove, and the other end is connected to the top cover connecting plate 16. When the internal buffer platform 13 moves due to vibration, the top cover buffer spring 14 absorbs the remaining vibration energy through its own elastic deformation, further reducing the impact of vibration on the buffer top cover 6. It is an important component to enhance the buffer performance of the top cover.
[0042] Top cover connecting top plate 16: slides in the sliding groove at the top of the internal buffer platform 13. Its top surface is provided with equally spaced top cover connecting threaded holes 15. On the one hand, it buffers vibration under the action of the spring by connecting with the top cover buffer spring 14. On the other hand, it cooperates with the top cover connecting assembly through the top cover connecting threaded holes 15 to realize the installation and fixation of the buffer top cover 6, ensuring the integrity of the entire top cover structure.
[0043] Internal protective spring 11: Fixed to the inner bottom surface of the top buffer groove of the top support platform 5. Under normal circumstances, it is in a certain pre-compression or natural state. When the vehicle encounters a severe impact, the internal protective spring 11 will respond quickly to provide additional upward support force for the top cover buffer assembly, prevent the top cover buffer assembly from being over-displaced or damaged due to excessive impact force, protect the internal parts of the shock absorber, and extend the service life of the shock absorber.
[0044] Buffer top cover 6: As the outermost component of the shock absorber buffer top cover, it directly contacts the relevant components of the vehicle. Its top surface has equidistantly distributed top cover connecting slots 12 for mating with the top cover connecting screws 7. The buffer top cover 6 is fixedly connected to the top cover connecting plate 16, which not only protects the internal structure, but also evenly transmits the shock-absorbing force to other components of the vehicle. At the same time, it also has a certain buffering performance, further improving the overall shock absorption effect.
[0045] Top cover connecting screw 7: Passes through the top cover connecting slot 12 of the buffer top cover 6 and is threaded to the top cover connecting threaded hole 15 of the top cover connecting top plate 16. It firmly fixes the buffer top cover 6 to the top cover connecting top plate 16, ensuring that the entire top cover structure remains stable during use and preventing the buffer top cover 6 from loosening and affecting the shock absorption effect.
[0046] Working principle: When this utility model is used, the inner bottom side of the damper top support rod 1 is slidably connected to the damper bottom support rod 3, and the outer top side is fixedly connected to the shock absorber buffer spring 2. The bottom surface of the shock absorber buffer spring 2 is fixed to the damper bottom support rod 3. This structure allows the damper top support rod 1 and bottom support rod 3 to slide relative to each other when the vehicle encounters vibration. The shock absorber buffer spring 2 initially buffers the vibration. The top surface of the damper top support rod 1 is fixedly connected to the buffer pad 4, and the top surface of the buffer pad 4 is fixed to the top support platform 5. Both have equidistantly distributed connecting holes 10 on their top surfaces, which are concentrically aligned with the connecting threaded holes 9 on the top surface of the damper top support rod 1. The shock absorber connecting screw 8 slides in the connecting hole 10 and is threadedly connected to the connecting threaded hole 9. The top surface of the top support platform 5 is also slidably connected to the shock absorber connecting screw 8, and the top of the top support platform 5 has a buffer groove. This component realizes the buffer connection between the buffer top cover and the shock absorber. The buffer pad 4 can buffer vibration and securely connect the various components. At the same time, the internal buffer platform 13 slides in the top buffer groove of the top support platform 5. A sliding groove is opened on its top, and the top cover buffer spring 14 is fixed in the sliding groove. The top surface of the top cover buffer spring 14 is connected to the top cover connecting plate 16, and the top cover connecting plate 16 slides in the sliding groove. The top surface of the top cover connecting plate 16 has equidistantly distributed top cover connecting threaded holes 15. This component provides a top buffer function for the buffer top cover 6 and further absorbs vibration energy. When subjected to severe impact, the internal protective spring 11 provides protection for the top cover buffer component to avoid damage. The top surface of the top cover connecting plate 16 fixes the buffer top cover 6. The top surface of the buffer top cover 6 has equidistantly distributed top cover connecting through grooves 12, which are concentrically aligned with the top cover connecting threaded holes 15 on the top cover connecting plate 16. The top cover connecting screw 7 slides in the top cover connecting through groove 12 and is threadedly connected to the top cover connecting threaded holes 15 to realize the fixed connection of the buffer top cover 6.
