Description

Technical Field

[0001] The utility model relates to the technical field of silicone sealing rings, in particular to a silicone sealing ring for automobiles. Background Art

[0002] In automotive engineering, sealing rings are an important form of automotive static sealing. There are hundreds of sealing rings used in automobiles. These sealing rings are widely used in large assemblies such as engines and accessory systems, transmission systems, steering systems, braking systems, and small assemblies such as pumps and valves. They play a role in sealing the liquid and gas inside the car and preventing the intrusion of rain and dust from the outside.

[0003] The life of the transmission seal is not very long, and the car needs to be replaced every 20,000 to 30,000 kilometers. The reason for the need to replace the seal regularly is that the seal is easy to deform after use, resulting in low sealing performance and low continuous sealing efficiency, which affects the use of the car.

[0027] 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.

[0028] See also Figure 1-5 , an embodiment provided by the utility model:

[0029] A silicone seal ring for automobiles, comprising: a silicone seal ring body 1, a plurality of elastic members, a first metal sheet 2, and a second metal sheet 3; Figure 1 , Figure 2 The silicone sealing ring body 1 includes an annular bottom wall 11, and a first annular side wall 12 and a second annular side wall 13 are fixedly connected to the annular bottom wall 11. The diameter of the second annular side wall 13 is larger than the diameter of the first annular side wall 12. The first annular side wall 12, the second annular side wall 13 and the annular bottom wall 11 form an annular groove; the elastic member is arranged in the annular groove, and the two ends of the elastic member are fixedly connected to the first annular side wall 12 and the second annular side wall 13 respectively; please refer to Figure 3-5 The first metal sheet 2 is an annular structure, and the first metal sheet 2 is arranged in the first annular side wall 12 ; the second metal sheet 3 is an annular structure, and the second metal sheet 3 is arranged in the second annular side wall 13 .

[0030] The first annular side wall 12 and the second annular side wall 13 of the silicone sealing ring body 1 are respectively provided with a first metal sheet 2 and a second metal sheet 3, which can improve the strength of the sealing ring and prevent it from being deformed. The first annular side wall 12 and the second annular side wall 13 of the silicone sealing ring body 1 are supported by multiple elastic parts. When the sealing ring is subjected to radial compression, the elastic parts can play a buffering role, thereby not easily causing damage to the silicone sealing ring body 1 and extending its service life.

[0031] Specifically, the first metal sheet 2 is provided with a plurality of first through holes 21, and the second metal sheet 3 is provided with a plurality of second through holes 31. The first metal sheet 2, the second metal sheet 3 and the silicone seal ring body 1 are connected as a whole. During processing, the first metal sheet 2 and the second metal sheet 3 are placed in a mold, and then the silicone liquid is poured to connect the first metal sheet 2, the second metal sheet 3 and the silicone as a whole. Since the first metal sheet 2 and the second metal sheet 3 are provided with the first through holes 21 and the second through holes 31 respectively, the first metal sheet 2, the second metal sheet 3 and the silicone are more firmly connected, and the structure is more stable.

[0032] Specifically, at least two first annular ridges 4 are provided on a side of the first annular side wall 12 away from the second annular side wall 13 , and the first annular ridges 4 are arranged at intervals along the axial direction of the silicone sealing ring body 1 .

[0033] Specifically, the side of the first annular protrusion 4 away from the first annular side wall 12 is an arc-shaped surface.

[0034] Specifically, a second annular convex strip 5 is provided on a side of the first annular side wall 12 away from the second annular side wall 13 .

[0035] For details, please refer to Figure 4 The second annular convex strip 5 is a trumpet-shaped structure.

[0036] In this embodiment, three first annular ridges 4 are provided. By providing a plurality of first annular ridges 4 and second annular ridges 5, multiple seals are formed between the sealing ring and the workpiece, thereby improving the sealing effect.

[0037] Specifically, the elastic member includes a compression spring 6 and an elastic column 7. There are multiple compression springs 6 and elastic columns 7, and the compression springs 6 and elastic columns 7 are evenly distributed along the circumferential direction, and the compression springs 6 and elastic columns 7 are arranged at intervals. The material of the elastic column 7 can be silicone or rubber. Under the elastic force of the compression spring 6, the contact between the sealing ring and the workpiece can be made closer, thereby improving the sealing effect.

[0038] Working principle: Install the sealing ring at the position where sealing is required. The first metal sheet 2 and the second metal sheet 3 increase the strength of the silicone sealing ring body 1, which is not easy to deform. When the sealing ring is subjected to radial extrusion, the elastic member can play a buffering role, so that it is not easy to cause damage to the sealing ring, and the service life is extended. Under the elastic force of the compression spring 6, the contact between the sealing ring and the workpiece is made closer, and the sealing effect is improved. The first annular convex strip 4 and the second annular convex strip 5 form multiple seals between the sealing ring and the workpiece, further improving the sealing effect.
