Description

Technical Field

[0001] The utility model relates to the technical field of automobile dust cover frames, in particular to an automobile frame dust cover. Background Art

[0002] The steering gear of a car is an important part of its steering system, which adjusts the direction of the car. Cars are mostly driven on roads and are easily affected by dust. The flying dust can easily fly into the steering gear, increasing the wear of the steering gear and reducing its service life. Therefore, dust covers are often installed at the heat dissipation ports of the steering gear to protect against dust.

[0003] In the prior art, the dust cover is used to block dust, mud and water on the outside during the driving of the car, preventing dust, mud and water from entering the shaft of the car steering gear, causing rapid wear of the car steering gear. However, the dust and mud will adhere to the surface of the dust cover, and the existing dust cover is usually made of rubber, and dust and mud can easily corrode the rubber, causing the dust cover to age quickly. Utility Model Content

[0004] According to the deficiencies in the prior art, the purpose of the utility model is to provide an automobile frame dust cover so as to solve the technical problems mentioned in the above background technology.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A dust cover for an automobile frame comprises a rubber bellows, wherein a rotating connector is arranged at the upper end of the rubber bellows, a fixed seal is arranged at the bottom end of the rubber bellows, an inner sleeve is arranged inside the rubber bellows, a plurality of paddles are arranged on the outer surface of the inner sleeve, and an elastic sheet is fixedly connected to the inner wall of the rubber bellows.

[0007] Furthermore, the rotating connecting member includes a fixed ring and a rotating ring, the fixed ring is fixedly connected to the upper pipe mouth of the rubber bellows, the rotating ring is located inside the fixed ring and is rotatably connected to the fixed ring, the inner ring wall of the fixed ring is provided with a rotating groove, the inside of the rotating groove is rotatably connected with an embedded ring, and the embedded ring is fixedly connected to the rotating ring.

[0008] Furthermore, the fixed seal includes a sealing plate and a sealing airbag. The sealing plate is sleeved on the outer surface of the lower pipe mouth of the rubber bellows and fixedly connected to the rubber bellows. The sealing airbag is fixedly installed on the bottom of the sealing plate. A threaded hole is opened on the circumferential side of the sealing plate.

[0009] Furthermore, the upper end of the inner sleeve is fixedly connected to the rotating ring, the bottom of the inner sleeve is rotatably connected to a positioning sleeve, and the positioning sleeve is fixedly connected to the inner wall of the lower pipe opening of the rubber bellows.

[0010] Furthermore, six paddles are provided, and the paddles are arranged in increasing order along the circumferential side of the inner sleeve.

[0011] Furthermore, six elastic sheets are provided, and the intervals between two adjacent elastic sheets are the same.

[0012] In summary, the present invention includes at least one of the following beneficial technical effects:

[0013] 1. The automobile skeleton dust cover drives the inner sleeve to rotate by rotating the automobile steering shaft, so that the paddle fixed on the outer surface of the inner sleeve paddles the elastic sheet, causing the elastic sheet to vibrate, and the vibration of the elastic sheet causes the tube wall of the rubber bellows to shake, thereby removing dust and muddy water on the outer surface of the rubber bellows to prevent them from corroding the rubber bellows, effectively achieving the effect of extending the service life of the rubber bellows;

[0014] 2. In this automobile skeleton dust cover, since the length of the paddles is set in increments, during the rotation of the inner sleeve, the elastic sheet is moved by paddles of different lengths, causing the elastic sheet to vibrate with different intensities, thereby changing the vibration intensity of the rubber bellows. In addition, through six evenly arranged elastic sheets, the contact frequency with the paddles is effectively increased, so that the vibration frequency of the rubber bellows is increased, thereby improving the removal efficiency of dust and muddy water, and preventing dust and muddy water from staying on the surface of the rubber bellows for a long time.
