[0001] The utility model relates to the technical field of new energy vehicles, in particular to a charging interface for new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include four major types: hybrid electric vehicles, pure electric vehicles, fuel cell electric vehicles, and other new energy vehicles. Unconventional automotive fuels refer to fuels other than gasoline and diesel.

[0003] In the process of realizing the present invention, the inventors found that the existing technology has the following problems: 1. Ordinary charging interfaces are troublesome to disassemble. When maintenance personnel conduct some online inspections, it is difficult to use detection tools to conduct comprehensive inspections of the interfaces due to problems such as small space around the interfaces and messy cables, which affects the inspection efficiency and accuracy. Since more complicated operations such as prying and separation are required, it is easy to accidentally damage other surrounding components, such as circuit boards and cables, thereby further increasing maintenance costs and even causing new faults; 2. Different electronic devices require different types of charging interfaces, the most common ones are five-hole and seven-hole. When a user has multiple devices with different interface requirements, a special charger is needed for each device, which not only increases the user's economic cost, but also leads to an increase in the number of chargers, which is very inconvenient to use and manage. Utility Model Content

[0004] The purpose of the present utility model is to provide a charging interface for new energy vehicles, so as to solve the problem raised in the above background technology that when maintenance personnel conduct some online inspections, it is difficult to conveniently use inspection tools to conduct comprehensive inspections of the interface due to the problems such as the small space around the interface and the messy cables, which affects the inspection efficiency and accuracy. To achieve the above purpose, the present utility model provides the following technical solutions: a charging interface for new energy vehicles, comprising a shell, a handle welded to the bottom of the shell, a connection seat installed below the handle by screws, a first interface installed on one side of the shell by screws, and a second interface provided on the other side of the first interface;

[0005] A spring is wound around the outer wall of the first interface, a movable ring is attached to the outer wall of the first interface, a connecting ring is welded to one side of the first interface, a baffle is welded to the outer wall of the connecting ring, and a steel ball is attached to the inner hole groove of the connecting ring;

[0006] A threaded interface is welded on one side of the second interface, and a fixed shell is threadedly connected to the outer wall of the threaded interface. A support plate is installed on one side of the fixed shell by screws, a fixing rod is installed on one corner of the support plate, and a charging head is installed in the middle of one side of the support plate by screws.

[0007] Further preferably, the inner wall of the movable ring is fitted to the connecting ring, and an "L"-shaped annular groove is provided on one side of the movable ring, and an "L"-shaped annular groove is provided on the other side of the movable ring.

[0008] Further preferably, the connecting ring forms an elastic structure through a spring.

[0009] Further preferably, the steel balls are distributed in an annular shape in the groove of the connecting ring.

[0010] Further preferably, the internal structural dimensions of the "L" annular groove on one side of the movable ring are consistent with the external structural dimensions of the baffle.

[0011] Further preferably, the outer wall of the second interface is provided with a "U"-shaped annular groove, and the outer diameter of one side of the second interface is consistent with the inner diameter of the connecting ring.

[0012] Further preferably, the internal structural dimensions of the fixing shell are consistent with the external wall structural dimensions of the threaded interface.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this utility model, the charging port only needs to push the movable ring horizontally to the other side to compress the spring and allow the steel ball to enter the "L"-shaped groove on one side, making it easy to disassemble.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] See also Figures 1 to 4 The utility model provides a technical solution: a new energy vehicle charging interface, comprising a shell 1, a handle 2 welded to the bottom of the shell 1, a connection seat 3 installed below the handle 2 by screws, a first interface 4 installed on one side of the shell 1 by screws, and a second interface 5 provided on the other side of the first interface 4;

[0023] A spring 401 is wound around the outer wall of the first interface 4, a movable ring 402 is attached to the outer wall of the first interface 4, a connecting ring 405 is welded to one side of the first interface 4, a baffle 403 is welded to the outer wall of the connecting ring 405, and a steel ball 404 is attached to the inner hole of the connecting ring 405;

[0024] A threaded interface 501 is welded on one side of the second interface 5, and a fixed shell 502 is threadedly connected to the outer wall of the threaded interface 501. A support plate 504 is installed on one side of the fixed shell 502 by screws. A fixing rod 505 is installed on the corner of one side of the support plate 504, and a charging head 503 is installed in the middle of one side of the support plate 504 by screws.

[0025] In this embodiment, Figure 3 As shown, the inner wall of the movable ring 402 is fitted to the connecting ring 405, and an "L"-shaped annular groove is provided on one side of the movable ring 402, and an "L"-shaped annular groove is provided on the other side of the movable ring 402; the "L"-shaped annular grooves provided on both sides of the movable ring 402 provide spatial position limitations for the subsequent installation and movement of the spring 401 and the steel ball 404, and are an important structural basis for realizing the quick connection and disassembly mechanism of the charging interface, so that each component can work together within a specific groove structure.

[0026] In this embodiment, Figure 3 As shown, the connecting ring 405 forms an elastic structure through the spring 401; when the movable ring 402 is pushed to compress the spring 401, the spring 401 can store elastic potential energy. When the movable ring 402 is released, the elastic force of the spring 401 can accurately drive the movable ring 402 back to the initial position, thereby pushing the steel ball 404 to complete the insertion or removal action between different grooves, ensuring the rapid switching of the charging interface connection status.

[0027] In this embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, the steel balls 404 are distributed in a ring shape in the groove of the connecting ring 405; the steel balls 404 can evenly contact and act on the relevant components. When connected, the steel balls 404 can be inserted into the "U"-shaped groove of the second interface 5 to achieve a stable connection of the charging interface. When disassembling, the steel balls 404 can be removed from the "U"-shaped groove, so that the interface can be separated smoothly, playing a key role in engagement and separation.

[0028] In this embodiment, Figure 3 As shown, the internal structural dimensions of the "L" annular groove on one side of the moving ring 402 are consistent with the external structural dimensions of the baffle 403; the baffle 403 can precisely match the groove on this side of the moving ring 402, and the baffle 403 plays a role in limiting excessive movement of the moving ring 402 and guiding its movement direction, thereby ensuring the accuracy and stability of the entire connection structure during operation.

[0029] In this embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, the outer wall of the second interface 5 is provided with a "U"-shaped annular groove, and the outer diameter of one side of the second interface 5 is consistent with the inner diameter size of the connecting ring 405; the "U"-shaped annular groove provides an accurate snap-in position for the steel ball 404, ensuring the stability during connection, and the consistent diameter size ensures that the second interface 5 can be smoothly and tightly inserted into the connecting ring 405, which is an important size matching condition for achieving fast and accurate connection of the charging interface, avoiding situations such as loose connection or difficult insertion.

[0030] In this embodiment, Figure 4 As shown, the internal structural dimensions of the fixed shell 502 are consistent with the outer wall structural dimensions of the threaded interface 501; the threaded connection method facilitates the replacement operation of the five-hole and seven-hole charging heads 503, ensuring that during the replacement process, the connection between the charging head 503 and the fixed shell 502 is tight and stable, and there will be no loosening or other problems that affect the charging function.

[0031] The usage and advantages of this utility model: When the new energy vehicle charging interface is used, the working process is as follows:

[0032] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, first push the movable ring 402 horizontally to the other side, so that the "L"-shaped groove on the other side of the movable ring 402 compresses the spring 401, and the steel ball 404 enters the "L"-shaped groove on one side, and is horizontally inserted into the second interface 5 into the connecting ring 405. Release the movable ring 402, and the pressure of the spring 401 drives the movable ring 402 back to the initial position. The steel ball 404 is stuck into the "U"-shaped groove of the second interface 5 on the inner side of the groove of the connecting ring 405, which is convenient for quick disassembly and installation of the charging interface. A threaded interface 501 is also provided on one side of the second interface 5, which is threadedly connected to the fixed shell 502, which is convenient for replacing the five-hole and seven-hole charging heads 503.
