Description

Technical Field

[0001] This utility model relates to the field of automotive component technology, specifically a sealing ring for an electric vehicle charging port. Background Technology

[0002] Electric vehicles are generally required to support both fast and slow charging. To save costs, a charging base with both fast and slow charging ports is usually installed on the vehicle body to connect the charging gun plug and charge the vehicle.

[0003] However, the purpose of using sealing rings in electric vehicles is to increase the seal between the charging gun and the charging port. However, the sealing rings in the existing technology do not fit well inside the charging port. This makes it easy for the sealing ring to fall off with the charging gun during the insertion and removal process, thereby affecting the sealing of the charging port and reducing its service life. Summary of the Invention

[0004] The purpose of this utility model is to provide a sealing ring for an electric vehicle charging port, so as to solve the problem mentioned in the background art that the sealing ring in the prior art does not fit well inside the charging port. This causes the sealing ring to fall off with the charging gun during the plugging and unplugging process, thereby affecting the sealing performance of the charging port and reducing the service life of the charging port.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sealing ring for an electric vehicle charging port, comprising a snap-fit ​​ring, wherein a connecting block is fixedly connected to the outer wall of the snap-fit ​​ring, and a first sealing ring and a second sealing ring are fixedly connected to the inner wall surface of the snap-fit ​​ring respectively, and a cavity is formed between the first sealing ring and the second sealing ring.

[0006] Preferably, the first sealing ring and the second sealing ring have a first arc angle at both ends of their surfaces.

[0007] Preferably, the inner wall of the snap ring has a second rounded corner at both ends.

[0008] Preferably, the snap ring and the connecting block, the first sealing ring and the second sealing ring are designed as an integral molded structure.

[0009] Beneficial effects

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0011] This invention solves the problems mentioned in the background art by setting a connecting block on the outer wall of the snap ring, so that the connecting block and the snap ring can be locked in the slot on the inner wall of the charging port. At the same time, a first arc angle is opened on the surface of the first sealing ring and the second sealing ring. With the above-mentioned structural cooperation, the problem is effectively solved.

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] In the description of this utility model, it should be noted that the terms "upper," "lower," "left," "right," "front," "rear," "inner," "outer," "vertical," and "horizontal," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] like Figure 1 This is a schematic diagram of a preferred embodiment of the sealing ring for an electric vehicle charging port. In this embodiment, the sealing ring for an electric vehicle charging port includes a snap-fit ​​ring 1. A connecting block 6 is fixedly connected to the outer wall of the snap-fit ​​ring 1. The connecting block 6 guides the snap-fit ​​ring 1 when it is snapped into the slot of the charging port, preventing it from falling out during use. The snap-fit ​​ring 1 has a thickness of 4mm-8mm. A first sealing ring 2 and a second sealing ring 3 are fixedly connected to the inner wall surface of the snap-fit ​​ring 1. The first sealing ring 2 and the second sealing ring 3 contact the outer wall of the charging gun to increase sealing. A cavity 7 is formed between the first sealing ring 2 and the second sealing ring 3. The cavity 7 increases the deformation of the first sealing ring 2 and the second sealing ring 3 after compression, preventing them from being squeezed out of the slot when they contact the outer wall of the charging gun. This structural design effectively solves the problems mentioned in the background art.

[0019] In this embodiment, the first sealing ring 2 and the second sealing ring 3 have a first arc angle 4 at both ends of their surfaces, and the snap ring 1 has a second arc angle 5 at both ends of its inner wall. This design reduces burrs at the edges and corners, and reduces the friction force when the charging gun is inserted into the charging port.

[0020] In this embodiment, the snap ring 1 and the connecting block 6, and the first sealing ring 2 and the second sealing ring 3 are designed as an integral molded structure; this structural design increases the connection strength between them and improves the service life of the sealing rings.

[0021] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
