Description

Technical Field

[0001] This utility model belongs to the field of shock absorber technology, specifically relating to a hyperbolic ultra-flexible airbag shock absorber. Background Technology

[0002] Air spring shock absorbers are widely used in the automotive industry, and there are many types of air spring shock absorbers. Among them, the telescopic air spring is one of the important types of air springs. Currently, most vehicles are equipped with telescopic air springs for shock absorption. Existing telescopic air spring shock absorbers consist of a metal cylinder and a rubber diaphragm, as detailed in the appendix to this application's specification. Figure 4 As shown; However, most existing vehicles are equipped with telescopic air spring shock absorbers. During use, the telescopic air spring structure has too strong a deformation capacity when dealing with large displacements or complex directional vibrations, making it impossible to compress the air slowly. In other words, the air compression shock absorption process is not smooth, which leads to poor shock absorption effect. Therefore, this utility model provides a hyperbolic ultra-flexible air spring shock absorber. Utility Model Content

[0003] The purpose of this invention is to provide a hyperbolic ultra-flexible airbag shock absorber to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hyperbolic ultra-flexible airbag shock absorber, including a damper, a connecting sleeve is provided on the outside of the damper, a limiting protrusion is provided at the bottom of the outside of the damper, a rubber sleeve is provided on the top of the connecting sleeve, a connecting cover is provided on the top of the rubber sleeve, and a locking ring is provided on the outside of the overlapping parts of the rubber sleeve, the connecting sleeve, and the connecting cover.

[0005] In a preferred embodiment, the inner walls at both ends of the rubber sleeve are provided with internal threads, and the outer side of the rubber sleeve is provided with two identical curved protrusions.

[0006] In a preferred embodiment, the end of the connecting sleeve facing the rubber sleeve is provided with an external thread that matches the internal thread of the rubber sleeve, the bottom end of the connecting sleeve abuts against the limiting protrusion, and a sealing ring is provided on the contact surface between the connecting sleeve and the damper. An air inlet is provided on one side of the connecting sleeve, and the interior of the connecting sleeve communicates with the interior of the rubber sleeve.

[0007] In a preferred embodiment, the connecting cover has an external thread that matches the internal thread of the rubber sleeve on the outside of the end facing the rubber sleeve, and the connecting cover has a through hole that matches the damper contraction rod inside, and a sealing ring is provided on the inner wall of the through hole.

[0008] In a preferred embodiment, the bottom end of the damper is fixedly connected to a first connecting end, and the top end of the damper contraction rod is threadedly connected to a second connecting end.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This hyperbolic ultra-flexible airbag shock absorber, by setting up a hyperbolic rubber sleeve, can effectively intercept and weaken vibration energy during the operation of the shock absorber due to the large natural frequency vibration value of the hyperbolic rubber sleeve. This greatly reduces the transmission of vibration along the structure, that is, the air compression shock absorption process is relatively gentle, which is stronger than the effect of the cylindrical shock absorber, thereby improving the shock absorption effect of the shock absorber itself. This hyperbolic ultra-flexible airbag shock absorber, with its threaded connecting cover and connecting sleeve, not only facilitates the assembly of the shock absorber, but also the locking ring effectively enhances the connection strength between the connecting cover and connecting sleeve and the rubber sleeve, preventing loosening of the connection due to vibration and other factors during use, thereby improving the stability and reliability of the entire shock absorber structure.

[0012] The present invention will be further described below with reference to the embodiments.

[0013] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0014] Please see Figures 1-4This utility model provides a hyperbolic ultra-flexible airbag shock absorber, including a damper 1, a connecting sleeve 2 made of rubber, the damper 1 having a limiting protrusion 103 at its bottom, a rubber sleeve 4 at its top, a connecting cover 3 at its top, and locking rings 5 ​​at the overlapping points of the rubber sleeve 4, the connecting sleeve 2, and the connecting cover 3. The end of the connecting sleeve 2 facing the rubber sleeve 4 has an external thread adapted to the internal thread of the rubber sleeve 4. The bottom end of the connecting sleeve 2 and the limiting protrusion 103 are connected... 3. The contact surface between the connecting sleeve 2 and the damper 1 is provided with a sealing ring. The connecting sleeve 2 is provided with an air inlet 201 on one side. The interior of the connecting sleeve 2 is connected to the interior of the rubber sleeve 4. The connecting cover 3 is provided with an external thread that matches the internal thread of the rubber sleeve 4 on the outside of the end facing the rubber sleeve 4. The interior of the connecting cover 3 is provided with a through hole that matches the retraction rod of the damper 1, and a sealing ring is provided on the inner wall of the through hole. The bottom end of the damper 1 is fixedly connected to the first connecting end 101, and the top end of the retraction rod of the damper 1 is threadedly connected to the second connecting end 102. During assembly, first screw the connecting sleeve 2 into the bottom of the rubber sleeve 4. Since the end of the connecting sleeve 2 facing the rubber sleeve 4 has an external thread that matches the internal thread of the rubber sleeve 4, the two can be tightly connected by rotating. Next, screw the connecting cover 3 into the top of the rubber sleeve 4. Similarly, the outer side of the connecting cover 3 facing the rubber sleeve 4 is provided with an external thread that matches the internal thread of the rubber sleeve 4. The rotation operation ensures that the connecting cover 3 and the rubber sleeve 4 are firmly connected. After completing the above connection, using the existing locking processing equipment, the two locking rings 5 ​​are respectively fitted onto the outside of the overlapping part of the rubber sleeve 4, the connecting sleeve 2, and the connecting cover 3, and locked and fixed. The locking rings 5 ​​also play a reinforcing role to prevent the connecting sleeve 2 and the connecting cover 3 from loosening with the rubber sleeve 4 during use. Then, first unscrew the second connecting end 102 to create conditions for the connecting sleeve 2 to be fitted onto the damper 1. Align one end of the connecting sleeve 2 with the damper 1 and fit it onto the outside of the damper 1. At this time, the bottom end of the connecting sleeve 2 abuts against the limiting protrusion 103 provided on the bottom of the outside of the damper 1, which plays a limiting role and prevents the connecting sleeve 2 from moving excessively on the damper 1. Finally, screw the second connecting end 102 on so that the top end of the damper 1's retraction rod is tightly connected to the second connecting end 102, completing the initial assembly of the overall structure. Finally, the rubber sleeve 4 is inflated through the air inlet 201 using an inflation device. Since the inside of the connecting sleeve 2 is connected to the inside of the rubber sleeve 4, the inflated gas can enter the inside of the rubber sleeve 4, causing the rubber sleeve 4 to expand and reach a suitable working state, thereby completing the assembly of the entire hyperbolic ultra-flexible airbag shock absorber.

[0015] In this embodiment, the inner walls at both ends of the rubber sleeve 4 are provided with internal threads, and the outer side of the rubber sleeve 4 is provided with two identical curved protrusions. When the hyperbolic ultra-flexible airbag shock absorber is installed on the vehicle at the location where shock absorption is needed, the shock absorber begins to function during vehicle operation. When the vehicle is subjected to vibration or impact, the damper 1 will move in extension and retraction accordingly. The rubber sleeve 4 has two identical curved protrusions on its outside. When subjected to force, its larger natural frequency vibration value can effectively intercept and weaken the vibration energy, greatly reducing the transmission of vibration along the structure, making the air compression damping process more gentle. This is stronger than the damping effect of existing telescopic shock absorbers. If the performance of the shock absorber changes during long-term use, the amount of gas inside the rubber sleeve 4 can be adjusted through the air inlet 201. Inflating the rubber sleeve 4 increases its stiffness, while deflating it decreases its stiffness, thus adapting to different working conditions and shock absorption requirements.

[0016] The working principle and usage process of this utility model are as follows: First, the connecting sleeve 2 with the matching external thread is rotated and screwed into the bottom of the rubber sleeve 4. Then, the connecting cover 3 with the matching external thread is rotated and screwed into the top of the rubber sleeve 4. After that, the two locking rings 5 ​​are respectively placed on the outside of the overlapping parts of the rubber sleeve 4, the connecting sleeve 2, and the connecting cover 3, and the existing locking processing equipment is used to compact them, thereby ensuring a tight connection and a stable structure. Next, unscrew the second connecting end 102, put the connecting sleeve 2 on the outside of the damper 1, and limit its bottom end to the limiting protrusion 103. Then screw on the second connecting end 102 to complete the initial assembly. Inflate the rubber sleeve 4, which is connected to the inside of the connecting sleeve 2, through the existing inflation device from the air inlet 201 to expand it to the appropriate state to complete the assembly. Finally, after the assembled shock absorber is installed on the vehicle at the location where shock absorption is needed, when the vehicle is subjected to vibration and impact, the damper 1 expands and contracts, and the hyperbolic structure of the rubber sleeve 4 can flexibly deform to adapt to different vibrations. Since the rubber sleeve 4 has two identical curved protrusions on its outside, when subjected to force, its own large natural frequency vibration value can effectively intercept and weaken the vibration energy, greatly reducing the transmission of vibration along the structure, making the air compression shock absorption process more gentle. This is stronger than the shock absorption effect of existing telescopic shock absorbers.

[0017] In the above scheme, it should be noted that both the air inlet 201 and the damper 1 are existing products, and the specific structure and working principle of the air inlet 201 and the damper 1 are existing public technologies, so they will not be described in detail here.
