It is mainly used to fill and fix the gaps between automotive parts, prevent the entry of moisture and dust, and ensure the sealing and stability of the vehicle. In addition, it can also absorb the vibrations and impact forces during vehicle driving, reduce vehicle noise, and improve the driving comfort.
[0003] However, the following problems exist in the existing rubber blocks: the flame retardancy of the rubber blocks is poor, and they are prone to burning or melting at high temperatures, causing damage to the vehicle. Moreover, the strength and rigidity of the rubber blocks are poor, and they are prone to breakage when pulled, affecting the use. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the disadvantages that in the prior art, the flame retardancy of the rubber block is poor, it is prone to burning or melting at high temperatures, causing damage to the vehicle, and the strength and rigidity of the rubber block are poor, and it is prone to breakage when pulled, affecting the use, and to propose a high-efficiency shock-absorbing automotive rubber expansion block.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A high-efficiency shock-absorbing automotive rubber expansion block includes an outer layer, an inner layer, and two side strips. The structure of the outer layer is a hollow structure. The inner layer is fixedly arranged on the inner wall of the outer layer. The two sides of the two side strips that are close to each other are respectively fixedly connected to the two bottom sides of the same outer layer. The top corners of the two sides of the two side strips that are far from each other are arc-shaped.
[0007] In a possible design, the material of the outer layer is flame-retardant polyurethane foam for flame retardancy. The top corners of both sides of the outer layer are arc-shaped. The material of the inner layer is natural rubber material.
[0008] In a possible design, connection blocks are fixedly connected to both the top and bottom sides of both sides of the inner layer. Grooves adapted to the connection blocks are provided on both the top and bottom inner walls of the outer layer. The four connection blocks are respectively fixedly arranged on the inner walls of the four grooves. The shapes of the four connection blocks are all T-shaped to prevent relative sliding between the inner layer and the outer layer.
[0009] In a possible design, reinforcing strips for strengthening the strength and rigidity of the rubber block are arranged inside the inner layer. The material of the reinforcing strips is carbon fiber material.
[0010] In a possible design, the number of the reinforcing strips is set to be multiple.
[0011] In a possible design, a plurality of mounting holes for facilitating the mounting and fixing of the rubber blocks are provided on both of the two side strips.
[0012] In this application, during use, the rubber blocks are mounted on an automobile through the side strips and the mounting holes. An outer layer made of flame-retardant polyurethane foam and an inner layer made of natural rubber provide an efficient shock-absorbing effect. Then, through the T-shaped connecting blocks on the inner layer, relative movement between the inner layer and the outer layer is prevented, ensuring the normal use of the rubber blocks. And through the special material of the outer layer, the flame retardancy of the rubber blocks is ensured, thereby ensuring the safety of the rubber blocks at high temperatures and reducing damage to the automobile. Reinforcing strips made of carbon fiber are provided in the inner layer, increasing the strength and rigidity of the rubber blocks, and further increasing the tensile strength of the rubber blocks, facilitating the use of the rubber blocks. At the same time, the number of the reinforcing strips is set to be multiple to further ensure the strength of the rubber blocks.
[0013] The beneficial effects of the present utility model are as follows:
[0014] In the present utility model, the provided outer layer and inner layer ensure the efficient shock-absorbing effect of the rubber blocks, and through the provided reinforcing strips and the outer layer of special material, the safety of the rubber blocks at high temperatures is ensured, and damage to the automobile is reduced. At the same time, the strength and rigidity of the rubber blocks are increased, and further the tensile strength of the rubber blocks is increased, facilitating the use of the rubber blocks.
