Description

Technical Field

[0001] This utility model belongs to the field of lip sealing ring technology, and particularly relates to a lip sealing ring for new energy vehicles. Background Technology

[0002] The lip seal ring in new energy vehicles is a component specifically designed for automotive sealing systems. Its main function is to provide efficient sealing performance and prevent leakage of liquids (such as oil, battery coolant, etc.) or gases (such as air).

[0003] For example, Chinese patent CN220870077U discloses a lip seal ring for new energy vehicles. This device supports the first seal ring with a second seal ring, thereby improving the support strength of the seal ring.

[0004] This patent uses a top block and a second protrusion to support the stop block and the first protrusion, reducing the contact area between the first sealing ring and the engine inner wall. However, it also increases the contact pressure between the first sealing ring and the engine inner wall, causing the frictional resistance between the first sealing ring and the engine inner wall to increase and the frictional damage rate of the first sealing ring to accelerate. Utility Model Content

[0005] The purpose of this utility model is to provide a lip seal ring for new energy vehicles to solve the problems mentioned in the background art. The lip seal ring includes a sealing ring body with a plurality of grooves on its surface to increase the number of contact surfaces generated when the sealing ring body seals. The sealing ring body has a cavity inside to accommodate lubricating material. The sealing ring body has a plurality of through holes that are connected to the cavity.

[0006] Preferably, the sealing ring body has a top surface, a bottom surface, an inner wall, and an outer wall, and the plurality of grooves are disposed on the inner wall and the outer wall of the sealing ring body.

[0007] Preferably, the plurality of tanks include:

[0008] A plurality of first grooves are formed at the edges of the inner and outer walls of the sealing ring;

[0009] A plurality of second slots are formed between a plurality of first slots.

[0010] Preferably, the depths of the first groove and the second groove are different.

[0011] Preferably, the first groove and the second groove have different dimensions.

[0012] Preferably, the sealing ring body is provided with a reinforcing component, which is used to increase the impact resistance of the sealing ring body.

[0013] Preferably, the reinforcing component includes:

[0014] Two third grooves are respectively formed on the top and bottom surfaces of the sealing ring body;

[0015] Two reinforcing members are installed in two third slots respectively.

[0016] Preferably, the reinforcing member is made of a rigid material.

[0017] Preferably, the hard material is a metal.

[0018] Preferably, the plurality of through holes are respectively disposed on the inner wall and the outer wall of the sealing ring body.

[0019] This application delivers lubricating material from inside the cavity to the surface of the sealing ring body through several through holes, thereby reducing the frictional force on the surface of the sealing ring body, reducing the frictional resistance between the first sealing ring and the inner wall of the engine, slowing down the frictional damage rate of the first sealing ring, and improving the service life of the sealing ring body.

[0027] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0028] To address the issue of rapid frictional damage at the contact surface, this embodiment provides a lip seal ring for new energy vehicles, such as... Figure 1 and Figure 5 As shown, it includes: a sealing ring body 100 for sealing, a cavity 410 formed on the sealing ring body 100 for lubrication, and several through holes 420.

[0029] like Figure 1 As shown, the sealing ring body 100 is the prior art. It is ring-shaped and made of elastic material. The sealing ring body 100 has a top surface M1, a bottom surface M2, an inner wall M3 and an outer wall M4. The sealing ring body 100 is used to complete the sealing operation of related workpieces of new energy vehicles.

[0030] like Figures 4-5 As shown, the cavity 410 and several through holes 420 are used to lubricate the surface of the sealing ring 100. Specifically, the cavity 410 has a square cross-sectional shape and an overall annular shape, extending along the contour of the sealing ring 100 and located inside the sealing ring 100. The cavity 410 is filled with a material that achieves a lubricating effect. The several through holes 420 are circular holes, respectively located on the inner wall M3 and outer wall M4 of the sealing ring 100. The cavity 410 and the several through holes 420 are connected, and the lubricating material inside the cavity 410 is transported to the surface of the sealing ring 100 through the several through holes 420, thereby reducing the friction on the surface of the sealing ring 100 and improving the service life of the sealing ring 100.

[0031] To enhance the sealing effect of the sealing ring 100 on the contact surface, a further solution may include... Figure 1 As shown, the sealing ring body 100 has several grooves on its surface. These grooves are used to increase the number of contact surfaces generated when the sealing ring body 100 performs sealing. Specifically, the grooves are located on the inner wall M3 and the outer wall M4 of the sealing ring body 100. Through the design of the grooves, when the sealing ring body 100 performs sealing, both ends of the grooves will form contact surfaces independently and complete the sealing operation independently. Compared with single-sided sealing, multi-contact-surface sealing has better fault tolerance and improves the sealing effect.

[0032] To further improve sealing performance, further solutions include, for example... Figure 1 As shown, the plurality of grooves includes: a plurality of first grooves 210 and a plurality of second grooves 220. The first grooves 210 are triangular grooves, and the plurality of first grooves 210 are formed at the edges of the inner wall M3 and the outer wall M4 of the sealing ring body 100; the second grooves 220 are triangular grooves, and the plurality of second grooves 220 are formed between the plurality of first grooves 210, such as... Figure 5As shown, the depth and size of the first groove 210 and the second groove 220 are different. Therefore, under the same contact conditions, the frictional force on the multiple contact surfaces formed between the first groove 210 and the second groove 220 will also be different. At this time, the contact surface with less friction will maintain the sealing effect for a longer time, thus improving the service life of the sealing ring 100.

[0033] To increase structural strength and prevent the sealing ring 100 from cracking under high load, a further solution is proposed, such as... Figure 1 As shown, a reinforcing component 300 is provided on the sealing ring body 100. The reinforcing component 300 can increase the impact resistance of the sealing ring body 100. Specifically, the reinforcing component 300 includes: two third grooves 310 and two reinforcing members 320. The two third grooves 310 are square annular and are respectively formed on the top surface M1 and bottom surface M2 of the sealing ring body 100. The two reinforcing members 320 are square annular and are respectively fixedly installed in the two third grooves 310. The two reinforcing members 320 are made of a hard material, preferably metal.

[0034] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
