The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0032] like Figures 1 to 7 As shown, the utility model is a car chassis suspension shock absorber, comprising: a shock absorber body 1, mounting plates 2 fixedly mounted on both ends of the shock absorber body 1, a protective mechanism for protecting the shock absorber body 1, and a cleaning mechanism for cleaning dust on the surface of the protective mechanism.

[0033] The mounting plate 2 is provided with a mounting hole, through which the shock absorber body 1 can be mounted on the chassis of a car for use.

[0034] The protection mechanism includes: a protection tube 1 3 and a protection tube 2 4 which are sleeved and installed on the shock absorber body 1, and an installation component for installing the protection tube 1 3 and the protection tube 2 4; the protection tube 1 3 is composed of two semicircular tubes 1; the protection tube 2 4 is composed of two semicircular tubes 2.

[0035] The protective tube 1 3 and the protective tube 2 4 are both installed on the outside of the shock absorber body 1, thereby protecting the shock absorber body 1. During the driving process of the car, the surface of the shock absorber body 1 can be prevented from being splashed with mud, which can cause corrosion and damage, thereby affecting the service life.

[0036] Since the protection tube 1 3 is sleeved on the outside of the protection tube 2 4 , the protection tube 1 3 and the protection tube 2 4 are slidably connected, so that the operation of the shock absorber body 1 is not affected during the mud blocking process.

[0037] In addition, the surfaces of the protective tube 1 3 and the protective tube 2 4 are painted with anti-rust paint, which greatly improves the service life of the protective tube 1 3 and the protective tube 2 4.

[0038] The mounting assembly includes: a mounting ring 6 fixedly mounted on the mounting plate 2, a plug-in rod 7 installed through the mounting ring 6, a linkage spring 8 for driving the plug-in rod 7 to reset, one end of the linkage spring 8 is fixedly connected to the plug-in rod 7, the other end of the linkage spring 8 is fixedly connected to the mounting ring 6, and a positioning member for positioning the protective tube 1 3 and the protective tube 2 4 during installation; the positioning member includes: a positioning block 5 fixedly mounted on the protective tube 1 3 and the protective tube 2 4, and a positioning groove provided on the mounting plate 2; the positioning block 5 is provided with a plug-in hole matching the plug-in rod 7.

[0039] When installing the protective tube 1 3 and the protective tube 2 4, first pull the adjacent connecting rod 7, and the connecting rod 7 drives the adjacent linkage spring 8 to deform. Since the protective tube 1 3 is composed of two semicircular tubes 1; the protective tube 2 4 is composed of two semicircular tubes 2; at this time, the positioning blocks 5 on the two semicircular tubes 2 are respectively inserted into the corresponding positioning groove cavities, so that the two semicircular tubes 2 can be positioned. On the one hand, it is convenient for the subsequent fixation of the two semicircular tubes 2, and on the other hand, the two semicircular tubes 2 can be quickly connected.

[0040] When the two semicircular tubes are positioned, the corresponding connecting rods 7 are loosened and reset under the elastic force of the linkage spring 8, so that the connecting rods 7 are inserted into the adjacent connecting holes, thereby fixing the two semicircular tubes.

[0041] Then, the two semicircular tubes are set on the outside of the two semicircular tubes, and the positioning blocks 5 on the two semicircular tubes are respectively inserted into the corresponding positioning groove cavities, so that the two semicircular tubes can be positioned. On the one hand, it is convenient to fix the two semicircular tubes later, and on the other hand, the two semicircular tubes can be quickly connected.

[0042] When the two semicircular tubes are positioned, the corresponding connecting rods 7 are loosened and reset under the elastic force of the linkage spring 8, so that the connecting rods 7 are inserted into the adjacent connecting holes, thereby fixing the two semicircular tubes.

[0043] By reversing the above process, the protective tube 1 3 and the protective tube 2 4 can be easily disassembled.

[0044] In summary, the provision of the mounting assembly facilitates the installation and removal of the protective tube 1 3 and the protective tube 2 4 , and the operation is simple, thereby facilitating the maintenance or replacement of the protective tube 1 3 and the protective tube 2 4 .

[0045] The cleaning mechanism includes: a fixed tube 9 fixedly mounted on the mounting plate 2, a movable rod 11 movably mounted in the fixed tube 9, a damping block 10 fixedly mounted at the end of the movable rod 11, the damping block 10 is slidably mounted in the fixed tube 9, the other end of the movable rod 11 is fixedly connected to the mounting plate 2, and an airbag 12 is fixedly mounted between the damping block 10 and the fixed tube 9, a return spring 14 and a nozzle 13 connected to the airbag 12 are fixedly mounted in the airbag 12.

[0046] When the vehicle is driving, the car chassis drives the mounting plate 2 to vibrate, the mounting plate 2 drives the movable rod 11 to move, and the movable rod 11 drives the damping block 10 to slide in the inner cavity of the fixed tube 9. When the damping block 10 moves downward, the airbag 12 can be compressed and the return spring 14 can be compressed. When the damping block 10 moves upward, the airbag 12 and the return spring 14 are restored, and this process is repeated.

[0047] When the airbag 12 is continuously compressed and restored, the gas in the airbag 12 can be ejected through the nozzle 13. The air outlet end of the nozzle 13 points to the protective tube 1 3 and the protective tube 2 4, so that the gas is sprayed to the outside of the protective tube 1 3 and the protective tube 2 4, thereby cleaning the soil on the outside of the protective tube 1 3 and the protective tube 2 4, reducing the corrosion damage of the soil to the protective tube 1 3 and the protective tube 2 4, and improving the service life.

[0048] In addition, the damping block 10, the airbag 12, and the return spring 14 cooperate with each other to provide auxiliary shock absorption to the chassis of the automobile, thereby further improving the shock absorption effect.

[0049] Working principle: When in use, the protective tube 1 3 and the protective tube 2 4 are both installed on the outside of the shock absorber body 1, thereby protecting the shock absorber body 1. During the driving of the car, the surface of the shock absorber body 1 can be prevented from being splashed with mud, which will cause corrosion and damage, affecting the service life. In addition, through the setting of the installation components, the protective tube 1 3 and the protective tube 2 4 can be easily installed and disassembled, and the operation is simple, thereby facilitating the maintenance or replacement of the protective tube 1 3 and the protective tube 2 4.

[0050] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.
