Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shock absorber buffer design, in particular to a buffer device for an automobile shock absorber. Background Technique
[0002] Most of the existing connection methods between automobile shock absorbers and automobile chassis are directly fixed through bolt eyelets without buffer measures. When the automobile is impacted or driving on a rough road, the buffer of only relying on the spring is far from enough, and the driving experience will be very poor. Therefore, it is necessary to design a buffer device for an automobile shock absorber to enhance the buffer effect.
[0003] Therefore, it is necessary to design a buffer device for an automobile shock absorber with strong practicability and good buffer effect. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a buffer device for an automobile shock absorber to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical scheme: A buffer device for an automobile shock absorber, including a base, one side of the base is fixedly connected with an outer cylinder, one side of the base is fixedly connected with an inner cylinder, wherein the inner cylinder is located inside the outer cylinder, and there is an oil groove between them. A sealing ring is arranged between the outer cylinder and the inner cylinder. A spring is arranged inside the inner cylinder. One end of the spring is fixedly connected with a first pressing plate. One side of the first pressing plate is fixedly connected with an eyelet. The first pressing plate is slidably connected with the inner wall of the inner cylinder. One end of the first pressing plate is fixedly connected with a connecting rod. One end of the connecting rod is fixedly connected with a second pressing plate. Oil is placed inside the inner cylinder and the base, and the oil storage is adapted to the displacement distance of the first pressing plate and cannot overflow.
[0006] According to the above technical scheme, a plurality of first through grooves are arranged on the lower side surface of the inner cylinder, a plurality of second through grooves are arranged on the upper side of the inner cylinder, and a third through groove is arranged on the surface of the second pressing plate.
[0007] According to the above technical scheme, a support rod is fixedly connected to one side of the base, and the support rod is fixedly connected to the surface of the outer cylinder.
[0008] Compared with the prior art, the beneficial effects achieved by the utility model are as follows:
[0009] (1) By arranging an oil groove, when the eyelet is under pressure and presses against the first pressing plate, it slides inward and squeezes into the inner cylinder. Since one side surface of the first pressing plate is fixedly connected with the spring, buffering can be carried out through the spring elasticity. Secondly, the first pressing plate drives the connecting rod and the second pressing plate to displace towards the base. There is oil inside the inner cylinder. When the second pressing plate presses down, resistance will be generated for secondary buffering. As the first pressing plate presses down, it will never reach the highest level that the oil can reach, so it will not overflow. This structure has a good buffering effect.
[0010] (2) By providing a through-groove structure, when the second pressing plate presses down, part of the hydraulic fluid can flow into the oil groove between the inner cylinder and the outer cylinder. There will be resistance when the hydraulic fluid passes through the first through-groove, which plays a buffering effect. If there is too much hydraulic fluid in the oil groove and it cannot flow back through the first through-groove, it will flow back into the inner cylinder through the second through-groove. The third through-groove allows the hydraulic fluid to pass through when the second pressing plate squeezes downwards, thereby increasing the resistance and making the buffering effect better.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0017] Please refer to Figures 1-4 , the present utility model provides a technical solution: a buffering device for an automobile shock absorber, including a base 1, one side of the base 1 is fixedly connected with an outer cylinder 3, one side of the base 1 is fixedly connected with an inner cylinder 6, wherein the inner cylinder 6 is located inside the outer cylinder 3, and an oil groove is provided therebetween. A sealing ring 4 is provided between the outer cylinder 3 and the inner cylinder 6. A spring 11 is provided inside the inner cylinder 6. One end of the spring 11 is fixedly connected with a first pressing plate 9. One side of the first pressing plate 9 is fixedly connected with a lifting ring 5. The first pressing plate 9 is slidably connected with the inner wall of the inner cylinder 6. One end of the first pressing plate 9 is fixedly connected with a connecting rod 10. One end of the connecting rod 10 is fixedly connected with a second pressing plate 12. Hydraulic fluid is placed inside the inner cylinder 6 and the base 1, and the storage amount of the hydraulic fluid is adapted to the displacement distance of the first pressing plate 9 and cannot overflow.
[0018] Specifically, the suspension ring 5 is pressed against the first pressing plate 9, causing it to slide inward and squeeze into the inner cylinder 6. Since one side surface of the first pressing plate 9 is fixedly connected to the spring 11, buffering can be achieved through the elastic force of the spring. Secondly, the first pressing plate 9 drives the connecting rod 10 and the second pressing plate 12 to displace towards the base 1. There is hydraulic oil inside the inner cylinder 6, and resistance will be generated when the second pressing plate 12 presses downwards for secondary buffering. As the first pressing plate 9 presses down, it will never reach the highest level that the hydraulic oil can reach, so it will not overflow. This structure has a good buffering effect.
[0019] A number of first through grooves 7 are provided on the lower side surface of the inner cylinder 6, a number of second through grooves 8 are provided on the upper side of the inner cylinder 6, and a third through groove 13 is provided on the surface of the second pressing plate 12.
[0020] Specifically, when the second pressing plate 12 presses down, some of the hydraulic oil can flow into the oil groove between the inner cylinder 6 and the outer cylinder 3. There will be resistance when the hydraulic oil passes through the first through groove 7, which plays a buffering role. If there is too much hydraulic oil in the oil groove and it cannot flow back through the first through groove 7, it will flow back into the inner cylinder 6 through the second through groove 8. The third through groove 13 also allows the hydraulic oil to pass through when the second pressing plate presses downwards, thereby increasing the resistance and making the buffering effect better.
[0021] A support rod 2 is fixedly connected to one side of the base 1, and the support rod 2 is fixedly connected to the surface of the outer cylinder 3.
[0022] Specifically, the support rod 2 is used to maintain the structural stability of the base 1 and the outer cylinder 3, making it more firm.
[0023] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
