Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorber technology, specifically a dustproof structure for an automotive shock absorber piston rod. Background Technology

[0002] The shock absorber is an important component of the car suspension system, and its performance directly affects the car's driving comfort and safety. During the car's operation, the piston rod of the shock absorber will frequently reciprocate, and external impurities such as dust and mud can easily adhere to the surface of the piston rod.

[0003] If dust and other impurities are not cleaned in a timely manner, the dust may contain corrosive substances that adhere to the outer wall of the hydraulic cylinder, causing corrosion to the metal surface. Corrosion reduces the metal strength of the hydraulic cylinder's outer wall, shortens the service life of the shock absorber, and may also affect the structural stability of the shock absorber, posing a safety hazard. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a dustproof structure for the piston rod of an automotive shock absorber, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dustproof structure for a piston rod of an automotive shock absorber, comprising a shock absorber body, a piston rod body slidably connected inside the shock absorber body, a protective mechanism provided around the piston rod body, and a dustproof mechanism provided at the bottom inside the protective mechanism.

[0006] The dustproof mechanism includes a mounting cylinder, which is located inside the protective mechanism. A telescopic rod is fixedly connected to the inside of the mounting cylinder, and a dust removal plate is fixedly connected to the inside of the telescopic rod. A spring is sleeved around the telescopic rod, and a rubber plate is fixedly connected to the outside of the dust removal plate. The rubber plate is fixedly connected to the inside of the mounting cylinder, and a mounting bolt is threaded inside the mounting cylinder. A slider is fixedly connected to the top of the mounting cylinder.

[0007] Preferably, the protective mechanism includes a mounting plate, which is slidably connected to the periphery of the piston rod body. A rotating bolt is inserted inside the mounting plate and slidably connected to the inside of the piston rod body. A nut is threadedly connected to the bottom periphery of the rotating bolt. A protective cylinder is fixedly connected to the inner bottom side of the mounting plate and slidably connected to the periphery of the shock absorber body.

[0008] Preferably, the inner side of the spring is fixedly connected to the inner side of the dust removal plate, and the outer side of the spring is fixedly connected to the inner side of the mounting cylinder. The spring and the telescopic rod work together to make the inner wall of the dust removal plate fit against the outer wall of the shock absorber body, so that when the dust removal plate moves, it can fit against the outer wall of the shock absorber body.

[0009] Preferably, the inner side of the protective cylinder is provided with a groove corresponding to the movement trajectory of the slider, and the slider is slidably connected inside the groove. Through the groove, the slider can slide inside the protective cylinder, so that the mounting cylinder can be initially installed inside the protective cylinder.

[0010] Preferably, the protective cylinder has a threaded hole inside that corresponds to the position of the mounting bolt, and the mounting bolt is threaded into the inside of the threaded hole. Through the threaded hole, the mounting bolt can install the mounting cylinder into the inside of the protective cylinder.

[0011] Preferably, the dust removal plate is disposed on the periphery of the shock absorber body, and the inner side of the dust removal plate is in close contact with the periphery of the shock absorber body. The dust removal plate can clean the dust on the outer wall of the shock absorber body.

[0012] Compared with the prior art, this utility model provides a dustproof structure for the piston rod of an automotive shock absorber, which has the following beneficial effects:

[0013] 1. The dustproof structure of the piston rod of the car shock absorber: In the dustproof mechanism, the combination of the telescopic rod and the spring allows the dust removal plate to adapt and fit with the movement of the piston rod. The elastic buffer of the spring can avoid hard friction damage to the surface of the piston rod. When the piston rod reciprocates, the dust removal plate scrapes off the surface dust simultaneously, cleaning the dust on the outer surface of the shock absorber body.

[0014] 2. The dustproof structure of the piston rod of this automotive shock absorber includes a protective mechanism in which a mounting plate and a protective cylinder are fixed to the periphery of the piston rod body by rotating bolts and nuts. When the piston rod slides within the shock absorber body, the mounting plate causes the protective cylinder to rise and fall. The protective cylinder, through a telescopic rod, causes a dust removal plate to move along the outer wall of the shock absorber body, thus cleaning the dust. Attached Figure Description

[0023] This utility model provides the following technical solution:

[0024] Example 1

[0025] Please see Figure 1-4 This utility model provides a technical solution: a dustproof structure for a piston rod of an automobile shock absorber, including a shock absorber body 1, a piston rod body 4 slidably connected inside the shock absorber body 1, a protective mechanism 2 arranged around the piston rod body 4, and a dustproof mechanism 3 arranged at the bottom inside the protective mechanism 2.

[0026] The dustproof mechanism 3 includes a mounting cylinder 31, which is located inside the protective mechanism 2. A telescopic rod 32 is fixedly connected to the inside of the mounting cylinder 31, and a dust removal plate 34 is fixedly connected to the inside of the telescopic rod 32. A spring 33 is sleeved around the telescopic rod 32, and a rubber plate 35 is fixedly connected to the outside of the dust removal plate 34. The rubber plate 35 is fixedly connected to the inside of the mounting cylinder 31, and a mounting bolt 36 is threaded inside the mounting cylinder 31. A slider 37 is fixedly connected to the top of the mounting cylinder 31.

[0027] Furthermore, the inner side of the spring 33 is fixedly connected to the inner side of the dust removal plate 34, and the outer side of the spring 33 is fixedly connected to the inner side of the mounting cylinder 31. Through the cooperation of the spring 33 and the telescopic rod 32, the inner wall of the dust removal plate 34 can fit against the outer wall of the shock absorber body 1, so that when the dust removal plate 34 moves, it can fit against the outer wall of the shock absorber body 1.

[0028] Furthermore, the dust removal plate 34 is disposed on the periphery of the shock absorber body 1, and the inner side of the dust removal plate 34 is in close contact with the periphery of the shock absorber body 1. The dust removal plate 34 can clean the dust on the outer wall of the shock absorber body 1.

[0029] Example 2

[0030] Please see Figure 1-4 Furthermore, based on Embodiment 1, the protective mechanism 2 further includes a mounting plate 24, which is slidably connected to the periphery of the piston rod body 4. A rotating bolt 23 is inserted inside the mounting plate 24, which is slidably connected to the inside of the piston rod body 4. A nut 22 is threadedly connected to the bottom periphery of the rotating bolt 23. A protective cylinder 21 is fixedly connected to the inner side of the bottom of the mounting plate 24, and the protective cylinder 21 is slidably connected to the periphery of the shock absorber body 1.

[0031] Furthermore, a groove corresponding to the movement trajectory of the slider 37 is provided on the inner side of the protective cylinder 21, and the slider 37 is slidably connected inside the groove. Through the groove, the slider 37 can slide inside the protective cylinder 21, so that the mounting cylinder 31 can be initially installed inside the protective cylinder 21.

[0032] Furthermore, the protective sleeve 21 has a threaded hole inside that corresponds to the position of the mounting bolt 36, and the mounting bolt 36 is threaded into the inside of the threaded hole. Through the threaded hole, the mounting bolt 36 can install the mounting sleeve 31 into the inside of the protective sleeve 21.

[0033] In actual operation, when this device is used, the mounting plate 24 is slid to the periphery of the piston rod body 4, and the mounting plate 24 can be installed on the top inner side of the piston rod body 4 by rotating the bolt 23 and the nut 22. This allows the protective cylinder 21 to protect the piston rod body 4 and also to prevent dust from entering the piston rod body 4.

[0034] After the mounting plate 24 and the protective cylinder 21 are installed, the mounting cylinder 31 is slid into the bottom inner side of the protective cylinder 21, allowing the slider 37 to slide into the inner side of the protective cylinder 21. The mounting cylinder 31 is rotated manually by the operator, allowing the slider 37 to slide inside the protective cylinder 21. The mounting cylinder 31 is then installed into the bottom inner side of the protective cylinder 21 using the mounting bolt 36, allowing the dust removal plate 34 to slide on the outer wall of the shock absorber body 1. The spring 33 and the telescopic rod 32 work together to ensure that the inner side of the dust removal plate 34 is in contact with the outer wall of the shock absorber body 1. When the piston rod body 4 slides inside the shock absorber body 1, the protective cylinder 21 drives the mounting cylinder 31 to slide on the outer wall of the shock absorber body 1, allowing the dust removal plate 34 to slide on the outer wall of the shock absorber body 1. The dust removal plate 34 can clean the dust on the outer wall of the shock absorber body 1, preventing dust from covering the shock absorber body 1 for a long time and corroding it.
