Description

Technical Field

[0001] The present invention relates to the technical field of rubber and plastic parts, and in particular to a functional rubber and plastic part for a vehicle. Background Art

[0002] To rapidly dampen vibrations between the vehicle frame and body, improving ride smoothness and comfort, automobile suspension systems are generally equipped with shock absorbers. Shock absorbers primarily consist of two components: a spring and a damper. The spring primarily supports the vehicle's weight, while the damper reduces vibrations. Shock absorbers are used to dampen the rebound of the spring after absorbing shock, as well as impacts from the road. They are widely used in automobiles to accelerate the damping of frame and body vibrations, improving ride smoothness. While shock-absorbing springs can filter out road vibrations when driving over uneven surfaces, the springs themselves undergo reciprocating motion. Shock absorbers are designed to dampen this spring bounce, making them a crucial automotive component.

[0003] The connection between the automobile shock absorber and the car body requires a top glue. The top glue absorbs the alternating impact load from the road surface. The top glue needs to have certain structural strength requirements. The top glue generally includes a rubber vulcanized part, an exoskeleton, and an inner skeleton. The existing connection structure between the rubber part and the exoskeleton and the inner skeleton is simple. Generally, the rubber part is wrapped in the exoskeleton, and the fulcrum points between the rubber part and the exoskeleton are dispersed. As a result, when buffering the load, the force cannot be timely and evenly dispersed between the exoskeleton and the rubber part, resulting in concentrated force on the exoskeleton and the rubber part, poor fatigue resistance, easy damage, shortening the use effect and service life of the top glue, and easily producing noise. In addition, during the manufacturing of the existing top glue, the surface of the rubber part forms "bubbles" due to the overflow of internal gas, resulting in poor appearance of the top glue rubber part and affecting the structural strength of the rubber.

[0004] Generally, shock absorber sleeves are made of rubber and plastic materials, but their elasticity and service life are difficult to meet actual requirements. It is very easy for the sleeve to break during the movement of the shock absorber, causing functional damage to the shock absorber sleeve, which directly affects the actual use effect of the shock absorber. It is urgent to design a new type of high-strength, good elasticity, shock-absorbing and pressure-resistant automotive functional shock absorber rubber and plastic parts to replace existing products. Summary of the Invention

[0005] Aiming at the deficiencies of the above-mentioned existing technologies, the main purpose of the present invention is to provide a vehicle-use functional rubber and plastic part. The rubber and plastic part improves the strength and stiffness and elasticity of the rubber and plastic part by embedding springs and soft porcelain materials in the rubber and plastic. The springs and non-Newtonian fluid gums can significantly absorb the strong vibrations and pressures generated instantaneously by the part, effectively ensuring the normal operation of the shock absorber. By strongly modifying the rubber and plastic material, the overall performance of the rubber and plastic part is greatly improved, and the service life of the rubber and plastic part is significantly extended. The rubber-spring combination form is adopted to significantly enhance the shock absorption and tensile resistance of the rubber and plastic part.
