Description

Technical Field

[0001] The utility model specifically relates to a dustproof rubber cover of an electronic brake system. Background Art

[0002] With the rapid development of the automotive industry and the increasing trend of intelligence, the application of electronic brake systems has become more and more widespread. With its advantages of precise control, rapid response and fault self-diagnosis, the system has played an important role in improving vehicle driving safety and comfort. However, the precision components of the electronic brake system are easily affected by external environmental factors, especially pollutants such as dust, moisture, and chemicals, which pose a serious threat to its normal operation. Electronic brake systems generally require protective measures to resist external damage.

[0003] The existing dust cover of the electronic brake system is relatively simple. In order to ensure the extension and retraction of the brake system, a through hole is usually directly opened at the folds of the dust cover to facilitate the exhaust of the air inside the cover when it is shortened. However, the through hole directly opened at the folds will be squeezed and deformed, resulting in poor exhaust effect. In addition, the design of ordinary dust covers is not sophisticated enough to meet the space and structural requirements of miniaturized and integrated electronic modules. In addition, ordinary sealing materials are also prone to aging, which affects the use effect. For this reason, we propose a dust-proof rubber cover for an electronic brake system. Utility Model Content

[0004] The utility model aims to provide a dustproof rubber cover for an electronic brake system to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a dustproof rubber cover for an electronic brake system, comprising:

[0006] A telescopic shield, wherein one end of the telescopic shield has a second sealing seat;

[0007] A support ring is fixed to the other end of the telescopic shield, and one end of the support ring is provided with a first sealing seat connected to the brake system;

[0008] Wherein, an exhaust hole for exhausting air is provided on the outer surface of the support ring, and a reinforcing rib staggered with the exhaust hole is provided on the inner side wall of the support ring.

[0009] Preferably, the edge of the second sealing seat is elliptical, and the inner diameter of the second sealing seat is the same as the inner diameter of the support ring.

[0010] Preferably, one end of the first sealing seat protrudes in a direction away from the support ring to form a flange.

[0011] Preferably, the reinforcing ribs are rectangular and are evenly distributed at four locations along the circumference of the support ring.

[0012] Preferably, the second sealing seat and the telescopic shield are an integrally formed structure, and one end of the second sealing seat is provided with a sealing groove that cooperates with an external braking system.

[0013] Preferably, the telescopic shield is made of EPDM rubber.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] By providing a support ring, reinforcing ribs and exhaust holes, it is avoided that traditional exhaust holes are opened on the telescopic shield, which would cause squeezing of the exhaust holes when the telescopic shield is telescopically deformed, thereby affecting the exhaust effect. The device is beneficial to ensuring the permeability of the overall exhaust through the provision of exhaust holes, and by adding reinforcing ribs, the strength of the support ring can be greatly improved, and the influence of deformation of the exhaust holes on the exhaust can be reduced. The second sealing seat is elliptical, which can greatly improve the force effect and save external space to meet the installation requirements of dustproof for miniaturized and integrated braking systems. The flange protruding outward at the first sealing seat can increase the contact force effect with the external braking system, improve the sealing, and ensure good dustproof performance after the device is installed.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 The utility model provides a technical solution: a dustproof rubber cover for an electronic brake system, comprising:

[0023] A telescopic shield 1, one end of which is provided with a second sealing seat 4, which is convenient for mating with a front connecting clamp 9 of an external braking system;

[0024] The support ring 2 is fixed to the other end of the telescopic shield 1, and one end of the support ring 2 is provided with a first sealing seat 3 connected to the brake system, so as to facilitate the cooperation with the rear connection clamp 10 of the external brake system, so as to quickly install the device;

[0025] Among them, the outer surface of the support ring 2 is provided with an exhaust hole 5 for exhaust, which is convenient for exhausting the inside when the telescopic cover 1 performs telescopic movement, and the inner wall of the support ring 2 is provided with a reinforcing rib 8 staggered with the exhaust hole 5, which is convenient for improving the strength of the support ring 2 and reducing the deformation at the exhaust hole 5 to avoid affecting the exhaust.

[0026] In this embodiment, preferably, the edge of the second sealing seat 4 is elliptical to avoid using a circular edge with a large outer diameter that would result in an outer diameter that is too large, affecting installation requirements in a narrow space. Using a circular edge with a small outer diameter would result in poor force bearing effect after installation, and the inner diameter of the second sealing seat 4 is the same as the inner diameter of the support ring 2.

[0027] In this embodiment, preferably, one end of the first sealing seat 3 is protruded in a direction away from the support ring 2 to form a flange 6, so as to improve the sealing performance after installation and increase the strength of the inner circle of the first sealing seat 3.

[0028] In this embodiment, preferably, the reinforcing ribs 8 are rectangular, and the reinforcing ribs 8 are evenly distributed at four locations along the circumference of the support ring 2 to facilitate better strength effect.

[0029] In this embodiment, preferably, the second sealing seat 4 and the telescopic shield 1 are integrally formed, and one end of the second sealing seat 4 is provided with a sealing groove 7 that cooperates with the external braking system to facilitate better sealing.

[0030] In this embodiment, preferably, the material of the telescopic shield 1 is EPDM rubber. Ordinary rubber is usually made of natural rubber or synthetic rubber. This patent adopts EPDM rubber which has the advantages of weather resistance, chemical resistance, high elasticity and aging resistance compared with ordinary rubber, which is convenient to extend the service life of the device and ensure the dustproof stability of the braking system after installation.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
