Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile air shock absorber, specifically to an automobile air shock absorber assembly with dustproof function. BACKGROUND

[0002] With the rapid development of automobile industry, automobile air shock absorber is widely used in modern automobile because of its excellent comfort and handling performance. As a key component of vehicle suspension system, air shock absorber not only can effectively buffer the impact force in the driving process, but also can automatically adjust the vehicle height according to the road conditions to improve the driving experience. However, in the actual application environment, especially in the harsh road conditions, the service life and performance of the shock absorber are often significantly affected by external factors.

[0003] The traditional dustproof design of automobile shock absorber mainly adopts two forms of rubber dust cover and metal dust cover. Although the rubber dust cover has a certain dustproof effect, due to its material properties, it is easy to age, lose elasticity and even crack after long-term use, resulting in a significant reduction in dustproof function. While the metal dust cover is durable, it is usually fixed by buckle or screw, which is not only inconvenient to install and disassemble, but also the fixed point is easy to loosen under the vibration of long-time driving, thus greatly reducing the dustproof effect. In addition, the existing dustproof design often ignores the convenience of shock absorber in maintenance. When the shock absorber needs to be checked and maintained regularly, the complex or difficult-to-disassemble dustproof device will greatly increase the maintenance difficulty and time cost.

[0004] Therefore, there is an urgent need for an automobile air shock absorber assembly with reasonable structure design, significant dustproof effect, convenient installation and disassembly, and effective prevention of loosening, to solve the technical problems of poor dustproof effect, short service life, and difficult maintenance of existing technology, thereby prolonging the service life of the shock absorber and improving the overall performance and driving comfort of the automobile.

[0046] Please refer toFigures 1-5 The utility model provides a technical scheme: a car air shock absorber assembly with dustproof function, it includes:

[0047] Shock absorber body 1;

[0048] Adjusting bearing 3 is fixed in the bottom of shock absorber body 1;

[0049] Piston rod 2 is arranged in the inside of shock absorber body 1 and adjusting bearing 3;

[0050] Shock absorbing spring 4 is arranged on the outside of piston rod 2;

[0051] Threaded ring 5 is connected to the outside of the end of piston rod 2 away from shock absorber body 1, and the top of threaded ring 5 is fixedly connected with adjusting ring 10;

[0052] Dust cover 6 is fixed to the outside of adjusting bearing 3, and dust cover 6 is arranged at the bottom of shock absorber body 1;

[0053] Positioning end 7 is fixed to the end of piston rod 2 away from shock absorber body 1, and the upper end outer surface of positioning end 7 is connected to the inner wall surface of threaded ring 5 through a threaded structure, and the bottom of dust cover 6 is connected to positioning end 7;

[0054] A plurality of groups of anti-loosening mechanisms are arranged in a regular annular array between threaded ring 5 and positioning end 7.

[0055] Specifically, the car air shock absorber assembly with dustproof function can effectively prevent external dust, sand and other impurities from entering the shock absorber during vehicle operation through the cooperative action of dust cover 6, positioning column 12 and elastic component. The L-shaped groove of the bottom of L ring 8 of dust cover 6 is tightly matched with the L-shaped groove of positioning end 7, and the threaded connection structure between threaded ring 5 and positioning end 7 makes dust cover 6 stable under various driving conditions and prevents dust cover 6 from falling off or shifting due to vibration, thereby continuously providing reliable dustproof protection.

[0056] An annular groove is formed in the top of positioning end 7, an L-shaped groove is formed in the bottom end of the annular groove, the bottom end of dust cover 6 extends to the annular groove, L ring 8 is fixedly connected to the bottom of dust cover 6, and L ring 8 is connected to the L-shaped groove. Specifically, the L-shaped groove of the bottom of L ring 8 of dust cover 6 is tightly matched with the L-shaped groove of positioning end 7, and the threaded connection structure between threaded ring 5 and positioning end 7 makes dust cover 6 stable under various driving conditions and prevents dust cover 6 from falling off or shifting due to vibration, thereby continuously providing reliable dustproof protection.

[0057] The inner wall of the dust cover 6 is provided with an anti-skid ring 9, the outer side of the anti-skid ring 9 and the outer side of the adjusting ring 10 are provided with anti-skid lines, and the adjusting ring 10 is arranged on the inner side of the anti-skid ring 9. Specifically, through the cooperation of the anti-skid ring 9 on the inner wall of the dust cover 6 and the anti-skid lines on the outer side of the adjusting ring 10, a friction enhancement mechanism is formed, which significantly improves the contact friction between the two and further enhances the stability of the overall structure.

[0058] The dust cover 6 is made of fluororubber material, and the outer side of the dust cover 6 is provided with a cutting-resistant layer made of aramid fiber material. Specifically, the dust cover 6 can also be made of nitrile rubber material, that is, a high and low temperature resistant rubber material is used. This material selection enables the dust cover 6 to maintain good elasticity and sealing performance in various extreme temperature environments. Whether it is hot summer or cold winter, the dust cover 6 can maintain the best working state and will not harden, become brittle or lose elasticity due to temperature changes. The outer aramid fiber cutting-resistant layer effectively enhances the wear resistance and puncture resistance of the dust cover 6, which can resist scratches from small stones and sharp objects flying on the road, greatly prolonging the service life of the dust cover 6. This material combination design not only improves the durability of the dust cover 6 in various harsh environments, but also ensures its long-term stable dustproof effect, reduces the maintenance and replacement frequency, reduces the use cost, and realizes the long service life and high performance of the shock absorber.

[0059] The anti-loosening mechanism comprises:

[0060] A positioning groove 14 is arranged in the inner part of the positioning end head 7;

[0061] A fastening hole 15 is arranged through the inner part of the positioning end head 7, and the fastening hole 15 is in communication with the positioning groove 14;

[0062] A sealing spring 11 is arranged in the positioning groove 14, and the bottom of the sealing spring 11 is fixed to the inner bottom of the positioning groove 14;

[0063] A through hole 16 is arranged in the bottom of the dust cover 6;

[0064] A positioning hole 17 is arranged in the bottom of the threaded ring 5;

[0065] A fastening plate 13 is fixedly connected to the top end of the sealing spring 11;

[0066] A positioning column 12 is gap-fitted through the fastening hole 15, and the positioning column 12 is fixedly connected to the fastening plate 13.

[0067] Specifically, by providing a plurality of anti-loosening mechanisms arranged in a circular array, the installation firmness of the threaded ring 5 and the positioning end 7 can be improved. The anti-loosening mechanism of the present application is designed ingeniously, and through the precise cooperation of the positioning column 12 and the positioning hole 17, the continuous supporting force provided by the sealing spring 11 ensures that the positioning column 12 can be accurately inserted into the positioning hole 17, and the positioning end 7 is firmly fixed. This structure not only enhances the overall stability, but also effectively solves the problem of loosening of the dust cover 6 caused by vibration during driving, so that the shock absorber can maintain the best working state under various complex road conditions, and the overall performance and service life of the automobile are improved.

[0068] The positioning column 12 abuts against the positioning hole 17 through the through hole 16, and the length of the positioning column 12 is greater than the length of the fastening hole 15. Specifically, the positioning column 12 has a synchronous elastic force on the fastening plate 13 and the positioning column 12 by the sealing spring 11, and the bottom of the positioning column 12 extends out of the outside of the positioning end 7, which is convenient for the operator to control and facilitates disassembly operation. When the shock absorber needs to be repaired, the positioning column 12 is only pulled away from the positioning hole 17 and the through hole 16, and then the positioning end 7 is rotated in the opposite direction, so that it can be easily separated from the threaded ring 5. The entire disassembly process does not require additional tools, greatly saving maintenance time and labor, improving work efficiency, and is particularly suitable for use in scenarios that require frequent maintenance.

[0069] Specifically, in use, the worker aligns and inserts the L-shaped ring 8 at the bottom of the dust cover 6 into the L-shaped slot of the positioning end 7, holds the bottom of the dust cover 6, so that the anti-slip ring 9 on the inner wall of the dust cover 6 contacts the outer wall of the adjusting ring 10, thereby holding the threaded ring 5, and then rotating the positioning end 7 to threadedly connect the positioning end 7 to the inside of the threaded ring 5. Then pull the positioning column 12 to move it downward, loosen the positioning column 12 after tightening the positioning end 7, and then fine-tune the positioning end 7. When the positioning column 12 is aligned with the through hole 16, the elastic support force of the fastening plate 13 in the positioning groove 14 by the elastic action of the sealing spring 11 can make the positioning column 12 inserted into the positioning hole 17 opened on the threaded ring 5, so that the positioning end 7 is fixed and firmly and reliably assembled on the threaded ring 5, ensuring the installation stability of the dust cover 6, thereby improving the stable and reliable dustproof effect and improving the service life. When the shock absorber body 1 needs to be repaired, the positioning column 12 is pulled away from the positioning hole 17 and the through hole 16, and then the positioning end 7 is rotated, the adjusting ring 10 is held by the anti-slip ring 9, so that the positioning end 7 is separated from the threaded ring 5, the L-shaped ring 8 is pulled away from the L-shaped slot, and the positioning end 7 is removed. After that, the shock absorber body 1 can be repaired.

[0070] Although the utility model has been explained in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
