Rubber cups are mainly used to prevent liquid or gas leakage and ensure the stability of pressure inside the system. It can prevent foreign impurities, dust and moisture from entering the mechanical system and protect the internal precision parts from contamination and damage. Rubber cups are widely used in multiple systems of automobiles.

[0003] For example, the patent with announcement number CN207701768U discloses a reinforced rubber leather cup, which includes a leather cup body and a copper skeleton, the leather cup body has a bowl-shaped cavity and a central through hole, the copper skeleton is arranged in the leather cup body, the outer wall and the lower end face of the copper skeleton are vulcanized and bonded to the leather cup body, and the upper end face of the copper skeleton is exposed; the copper skeleton includes an upper circular ring segment, a lower circular ring segment and a transition segment connecting the upper circular ring segment and the lower circular ring segment, the outer diameter of the upper circular ring segment is smaller than the outer diameter of the lower circular ring segment; the copper skeleton has a skeleton through hole that is coaxial and has the same diameter as the central through hole. The rubber leather cup of the utility model is provided with a copper skeleton, which improves the strength and wear resistance of the product; the outer diameter of the copper skeleton is set as a variable diameter structure, and the interface vulcanization bonding force with the leather cup body is strong, and the structure is firm.

[0004] However, the rubber sealing portion of the component is not provided with a part for rounded transition. Since the sealing transition part adopts a blunt angle design, it is easy to cause fatigue cracking of the material of the rubber cup at the stress concentration point, and the service life of the rubber cup cannot be extended. Utility Model Content

[0006] The technical solution adopted in the present application is as follows: it includes a rubber sealing ring, the interior of the rubber sealing ring includes a sealing ring base, the outer side of the sealing ring base is fixedly installed with a sealing ring fillet, the outer side of the sealing ring fillet is fixedly installed with a rubber ring, and the outer surface of the rubber ring is fixedly installed with a sealing lip.

[0007] By adopting the above technical scheme, the inside of the rubber sealing ring includes a sealing ring base, the outside of the sealing ring base is fixedly installed with a sealing ring fillet, the outside of the sealing ring fillet is fixedly installed with a rubber ring, and the outer surface of the rubber ring is fixedly installed with a sealing lip. The rubber sealing ring is made of polypropylene rubber material as a whole, has excellent oil resistance, can effectively resist the erosion of engine oil, fuel and other lubricants, and prevent lubricant leakage. Its main function is to provide effective sealing in the automotive system to prevent liquids, gases or dust and other substances from leaking or entering the system, thereby ensuring the normal operation and performance of the system. The sealing ring base provides a fixed point and a supporting structure, so that the rubber sealing ring can be stably installed inside the rubber cup as a whole, which can ensure that the rubber sealing ring will not move or fall off during operation. The rounded corner design of the sealing ring fillet can make the stress acting on the rubber sealing ring more evenly distributed, avoid local stress concentration, and make the stress distribution more even. The rubber ring is more uniform and reduces material fatigue, avoiding fatigue cracking in places where stress is concentrated. At the same time, the rounded corner design of the sealing ring can increase the toughness of the product, better withstand external stress and pressure, and reduce the risk of rupture or damage. In addition, the increase in toughness can optimize the fit between the rubber sealing ring and the contact surface, improve the sealing effect, ensure the normal operation of the product and meet the performance requirements. The rubber ring can provide an additional sealing layer on the outside of the sealing ring fillet to fill potential gaps and irregular surfaces and enhance the overall sealing effect. The sealing lip serves as an outer protective layer to reduce direct contact and wear on the surface of the rubber ring, thereby extending the service life of the rubber ring and reducing early wear caused by the external environment and friction. By setting a component with excessive rounded corners on the rubber sealing part of the component, the rounded corner design can reduce material fatigue and reduce the risk of fatigue cracking caused by stress concentration, thereby improving the fatigue resistance of the sealing ring and extending its service life.

[0012] In a preferred embodiment, a spring ring is fixedly mounted on the inner side of the support ring.

[0013] By adopting the above technical solution, a spring ring is fixedly installed on the inner side of a support ring. The spring ring is made of stainless spring steel and can be embedded in the inner side of the sealing component to improve the sealing ability.
