Technical Field

[0001] This utility model relates to the field of charging interface technology for new energy vehicles, and in particular to a charging interface and vehicle using a C-type sealing method. Background Technology

[0002] With the increasing demand for diversified automotive energy sources, electric vehicles are increasingly integrated into the automotive market, giving them greater room for development in the automotive sector. The most significant characteristic of electric vehicles is that they are powered by charging, ensuring normal vehicle operation.

[0003] Charging is an essential function of electric vehicles, and designing a reasonable charging structure on the vehicle body is a necessary condition for realizing this function. In terms of the vehicle body, designing a reasonable charging port structure to ensure the installation of charging sockets is one of the essential aspects to consider in the development of electric vehicles.

[0004] The current charging interface has a problem with its large sealing profile at the tail, which can deform after long-term use and aging, making it easy for the sealing protection of the charging interface tail cavity to fail. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a charging interface and automobile with a C-type sealing method, so as to solve the technical problem that the sealing protection of the rear cavity of the charging interface is prone to failure after long-term aging and use.

[0006] To achieve the above objectives, this utility model employs the following technical solution: In a first aspect, this utility model provides a charging interface using a C-type sealing method, comprising: The interface body has a sealing groove around its tail edge, and a sealing ring is provided on the inner wall of the sealing groove near the middle of the interface body. An assembly gap is formed between the inner wall of the sealing groove away from the middle of the interface body and the sealing ring. The tail cover has a sealing part around its front edge. After the tail cover is assembled with the interface body, the sealing part fills the assembly gap and interferes with and squeezes the sealing ring.

[0007] Optionally, the sealing ring is fixed in the sealing groove by assembly, bonding, secondary injection, or secondary molding.

[0008] Optionally, the outer wall of the sealing ring is provided with a plurality of protrusions that surround the sealing ring.

[0009] Optionally, the cross-section of the protrusion is triangular or semi-circular.

[0010] Optionally, the interface body has multiple terminal mounting holes in the middle. After a terminal sealing ring is provided on the outer wall of the terminal, it is assembled into the terminal mounting hole. The outer wall of the terminal sealing ring interferes and is squeezed with the inner wall of the terminal mounting hole.

[0011] Optionally, the tail cover has multiple cable mounting holes in the middle. After the cable is fitted with a cable sealing ring on its outer wall, it is assembled into the cable mounting hole. The outer wall of the cable sealing ring interferes and squeezes with the inner wall of the cable mounting hole.

[0012] Optionally, the interface body and the tail cover are connected by a snap-fit.

[0013] Secondly, this utility model provides a car, including a charging interface with a C-type sealing method as described above.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This invention provides a charging interface with a C-type sealing method. When the interface body and the tail cover are fastened together, the sealing ring and the sealing part fit tightly, ensuring the sealing and protection performance of the charging interface tail cavity. Since both the sealing ring and the sealing part are arranged around the connection between the interface body and the tail cover, they can be well applied even if the contour of the sealing area is large. At the same time, each time it is installed, the sealing part needs to fill the assembly gap. The assembly gap restricts and protects the sealing part from deformation, ensuring the reliability of the sealing protection after long-term aging and use. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0017] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model 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," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Example 1:

[0020] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a charging interface with a C-type sealing method, including an interface body 1 and a tail cover 2; a sealing groove 11 is provided around the tail edge of the interface body 1, and a sealing ring 12 is provided on the inner wall of the sealing groove 11 near the middle of the interface body 1, and an assembly gap is formed between the inner wall of the sealing groove 11 away from the middle of the interface body 1 and the sealing ring 12; a sealing part 21 is provided around the front edge of the tail cover 2, and after the tail cover 2 is assembled with the interface body 1, the sealing part 21 fills into the assembly gap and interferes with and squeezes the sealing ring 12.

[0021] The interface body 1 and the tail cover 2 are connected by a snap-fit ​​mechanism. When the interface body 1 and the tail cover 2 are fastened, the sealing ring 12 and the sealing part 21 fit tightly together, ensuring the sealing and protection performance of the charging interface tail cavity. Since both the sealing ring 12 and the sealing part 21 are arranged around the connection between the interface body 1 and the tail cover 2, they can be well-suited even if the sealing area has a large profile. Because the sealing part 21 needs to fill the assembly gap with each installation, the assembly gap restricts and protects the sealing part 21 from deformation, ensuring reliable sealing and protection after long-term aging.

[0022] Specifically, in this embodiment, the sealing ring 12 is fixed in the sealing groove 11 by means of assembly, bonding, secondary injection, or secondary molding. The outer wall of the sealing ring 12 is provided with multiple protrusions surrounding it. The cross-section of the protrusions is triangular or semi-circular. These surface protrusions allow for better interference and compression with the sealing part 21, improving sealing performance.

[0023] like Figure 3 As shown, in addition to ensuring the sealing and protection performance at the connection between the interface body 1 and the tail cover 2, the interface body 1 has multiple terminal mounting holes 13 in the middle. Terminals 14 are fitted with terminal sealing rings 15 on their outer walls and then assembled into the terminal mounting holes 13. The outer wall of the terminal sealing rings 15 interferes with and is pressed against the inner wall of the terminal mounting holes 13. The tail cover 2 has multiple cable mounting holes 22 in the middle. Cables 23 are fitted with cable sealing rings 24 on their outer walls and then assembled into the cable mounting holes 22. The outer wall of the cable sealing rings 24 interferes with and is pressed against the inner wall of the cable mounting holes 22. By adding sealing structures to the terminals 14 and cables 23 on the interface body 1 and the tail cover 2, the overall sealing and protection performance of the charging interface is further improved.

[0024] Example 2:

[0025] Based on the charging interface with a C-type sealing method provided in Embodiment 1, this utility model embodiment provides a car including the charging interface with a C-type sealing method as described above.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
