Description

Technical Field

[0001] The utility model relates to the field of rubber shock-absorbing pads, in particular to a buffer rubber shock-absorbing pad. Background Art

[0002] It is inevitable that the car doors will be opened and closed frequently during use. During the closing process, in order to ensure that the doors are closed tightly, sufficient force is required when closing the doors. However, in this way, the doors will collide violently with the car body when closing, which can easily cause damage to the vehicle.

[0003] In order to avoid this problem, in the prior art, a shock-absorbing pad is arranged at the contact position between the door and the vehicle body. The shock-absorbing pad is made of rubber and has extremely strong elasticity. It can collide with the door and cushion the door when closing the door, such as a shock-absorbing rubber pad for a door with publication number CN211448255U.

[0004] During actual use, the movement trajectory of the car door is not a straight line, but a rotation around the door hinge. During the rotation, the car door contacts the shock-absorbing pad, and then the car door continues to rotate and compresses the shock-absorbing pad. During the compression of the shock-absorbing pad, further rotation of the car door will cause the contact position between the car door and the shock-absorbing pad to change, and the car door will slide relative to the shock-absorbing pad. The friction between the traditional shock-absorbing pad and the contact surface of the car door is relatively large, which will cause the shock-absorbing pad to deform and be damaged during the sliding process. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a buffering rubber shock-absorbing pad, which allows the lubricating oil to be adsorbed on the cotton cloth cover plate. The car door contacts the cotton cloth cover plate during the process of squeezing the rubber pad. The lubricating oil adsorbed by the cotton cloth cover plate reduces the friction between the two. The lubricating oil can make the relative movement between the two smoother, avoiding deformation or damage of the rubber pad caused by friction resistance, and can effectively solve the problems in the background technology.

[0006] To achieve the above object, the technical solution adopted by the utility model is: a buffer rubber shock-absorbing pad, comprising a fixed shell, wherein an elastic rubber pad is arranged inside the fixed shell, and the elasticity of the rubber pad is used to buffer the impact force when the door is closed, and a detachable cotton cover is arranged on the front side of the rubber pad, and the cotton cover can absorb lubricating oil;

[0007] A lubrication assembly is provided inside the fixed shell, and the lubrication assembly includes a cotton rope penetrating the rubber pad, a rubber sleeve is fixedly provided at the outer end of the cotton rope, a mounting groove is provided at the front side of the rubber pad, and a sponge block is fixedly provided at the front end of the cotton rope extending into the mounting groove;

[0008] An oil storage box filled with lubricating oil is fixedly provided on the inner wall of the fixed shell, a detachable sealing cover is provided at the front end of the oil storage box, the rear end of the cotton rope extends into the oil storage box and is immersed in the lubricating oil, the lubricating oil is absorbed by the cotton rope and conducted to the sponge block.

[0009] Furthermore, the front end of the rubber pad extends to the front side of the fixed shell, and a bottom plate is provided on the rear side of the rubber pad. The bottom plate is located inside the fixed shell, and the outer ends of the rubber pad and the bottom plate are in contact with the inner wall of the fixed shell, so that the interior of the fixed shell is in a relatively closed state.

[0010] Furthermore, a plurality of through holes are formed on the bottom plate, and the rubber pads are squeezed into the through holes after being compressed, so that the rubber pads have a larger elastic space.

[0011] Furthermore, a plurality of mounting plates are fixedly provided on the outer end of the fixing shell, and threaded holes penetrating the mounting plates are provided on the mounting plates, and the fixing shell is mounted on the body of the car through the mounting plates.

[0012] Furthermore, two springs are provided on the rear side of the bottom plate, and the rear ends of the springs are fixedly connected to the inner wall of the fixed shell. The elastic force of the springs is used to push the rubber pad and the bottom plate back to their initial positions after being compressed.

[0013] Furthermore, the top of the fixed shell is provided with ventilation micropores, the top of the ventilation micropores is provided with a dustproof net for filtering dust, and the dustproof net is embedded in the top of the fixed shell.

[0014] Compared with the prior art, the utility model provides a buffer rubber shock-absorbing pad, which has the following beneficial effects:

[0015] By setting up a lubrication component, the lubricating oil inside the oil storage box is guided to the sponge block through a cotton rope. When the rubber gasket is squeezed, the lubricating oil is adsorbed on the cotton cloth cover. The car door comes into contact with the cotton cloth cover during the process of squeezing the rubber gasket. The lubricating oil adsorbed by the cotton cloth cover reduces the friction between the two. The lubricating oil can make the relative movement between the two smoother and avoid deformation or damage of the rubber gasket caused by friction resistance.

[0016] When the car door is closed, as the air inside the fixed shell is slowly discharged through the ventilation pores, the rubber pad will gradually stretch under the action of elastic force and push the bottom plate backwards, causing the bottom plate to move backwards. After the front side of the rubber pad is compressed and deformed by the impact of the car door, the rubber pad stretches backwards to reduce the degree of deformation, thereby avoiding damage to the rubber pad due to long-term compression and large deformation.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1-5 As shown, the utility model provides a buffer rubber shock-absorbing pad, comprising a fixed shell 1, wherein an elastic rubber pad 2 is arranged inside the fixed shell 1, and the elasticity of the rubber pad 2 is utilized to buffer the impact force when the door is closed, and a detachable cotton cover sheet 3 is arranged on the front side of the rubber pad 2, and the cotton cover sheet 3 can absorb lubricating oil;

[0025] A lubrication assembly 6 is provided inside the fixed shell 1, and the lubrication assembly 6 includes a cotton rope 602 that penetrates the rubber pad 2, and a rubber tube sleeve 603 is fixedly provided at the outer end of the cotton rope 602. A mounting groove 7 is provided at the front side of the rubber pad 2, and a sponge block 601 is fixedly provided at the front end of the cotton rope 602 extending into the mounting groove 7;

[0026] An oil storage box 605 filled with lubricating oil is fixedly provided on the inner wall of the fixed shell 1, and a detachable sealing cover 604 is provided at the front end of the oil storage box 605. The rear end of the cotton rope 602 extends into the interior of the oil storage box 605 and is immersed in the lubricating oil. The lubricating oil is absorbed by the cotton rope 602 and transferred to the sponge block 601.

[0027] The shock-absorbing pad is installed on the body of the car, with the rubber pad 2 facing the car door, and ensuring that the car door can contact the rubber pad 2 after closing, and lubricating oil is installed inside the oil storage box 605. After the oil storage box 605 is closed by using the sealing cover plate 604, the lubricating oil in the oil storage box 605 soaks the rear end of the cotton rope 602, and the lubricating oil is transferred to the sponge block 601 along the cotton rope 602, and the sponge block 601 is also adsorbed with the lubricating oil. When the rubber pad 2 is squeezed by the car door, the sponge block 601 embedded in the installation groove 7 will also be squeezed and the lubricating oil adsorbed inside will be squeezed out. The squeezed out lubricating oil makes the cotton cloth cover sheet 3 also contaminated with the lubricating oil, and the car door contacts the cotton cloth cover sheet 3 in the process of squeezing the rubber pad 2. The lubricating oil adsorbed by the cotton cloth cover sheet 3 reduces the friction between the two. When the car door contacts the cotton cloth cover sheet 3 and moves relative to each other, the lubricating oil can make the relative movement between the two smoother, avoiding the deformation or damage of the rubber pad 2 caused by friction resistance.

[0028] During use, the impact force of the door is buffered by the elastic deformation of the rubber pad 2. Figure 2 , 3 As shown, the front end of the rubber pad 2 extends to the front side of the fixed shell 1, and a bottom plate 8 is provided on the rear side of the rubber pad 2. The bottom plate 8 is located inside the fixed shell 1. The outer ends of the rubber pad 2 and the bottom plate 8 are in contact with the inner wall of the fixed shell 1, so that the interior of the fixed shell 1 is in a relatively closed state.

[0029] The bottom plate 8 is provided with a plurality of through holes 9 , and the rubber pad 2 will be squeezed into the through holes 9 after being pressed, so that the rubber pad 2 has a larger elastic space.

[0030] When the vehicle door is closed, the moving vehicle door pushes the rubber pad 2 backwards, and the rubber pad 2 pushes the bottom plate 8 backwards. The rubber pad 2 is deformed due to the force, and the rubber pad 2 located at the through hole 9 is also squeezed into the through hole 9 due to the deformation due to the force. The through hole 9 provides more deformation space for the rubber pad 2, and the deformation of the rubber pad 2 uses its elastic force to cushion the impact of the vehicle door.

[0031] To install the shock absorber, Figure 1 , 3 As shown in FIG. 4 , a plurality of mounting pieces 4 are fixedly provided at the outer end of the fixing shell 1 . The mounting pieces 4 are provided with threaded holes penetrating the mounting pieces 4 . The fixing shell 1 is mounted on the body of the automobile through the mounting pieces 4 .

[0032] Two springs 10 are provided at the rear side of the bottom plate 8, and the rear ends of the springs 10 are fixedly connected to the inner wall of the fixed shell 1. The elastic force of the springs 10 is used to push the rubber pad 2 and the bottom plate 8 back to the initial position after being compressed.

[0033] A ventilation micropore 11 is provided at the top of the fixed shell 1 , and a dustproof net 5 for filtering dust is provided at the top of the ventilation micropore 11 . The dustproof net 5 is embedded in the top of the fixed shell 1 .

[0034] When the door is closed, the rubber pad 2 is squeezed by the door and pushes the bottom plate 8 backward, squeezing the air inside the fixed shell 1. After being squeezed, the air is discharged outward through the air-permeable micropores 11. However, the size of the air-permeable micropores 11 is small, which limits the speed of air discharge. The air in the fixed shell 1 cannot be discharged quickly. Therefore, when the door is closed, the rubber pad 2 cannot move backward quickly and will still be deformed due to the impact of the door. However, after the door is closed, as the air inside the fixed shell 1 is slowly discharged through the air-permeable micropores 11, the rubber pad 2 will gradually stretch under the action of elastic force and push the bottom plate 8 backward, so that the bottom plate 8 moves backward and the spring 10 is compressed. In this way, after the front side of the rubber pad 2 is compressed and deformed by the impact of the door, the rubber pad 2 reduces the degree of deformation by stretching backward, thereby avoiding damage to the rubber pad 2 due to long-term compression and large deformation.

[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
