DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] like Figure 1-3As shown, the new energy vehicle charging socket includes a seat body 1, on which a locking structure 2 for locking the external charging gun head and a fixedly connected charging structure 3 are provided. The locking structure 2 includes a push button 21, a push block 22, a limit rod 23, a locking block 24 and a reset member 25. The push button 21 is fixedly connected to the push block 22, the push block 22 matches the limit rod 23, the push block 22 matches the locking block 24, and the reset member 25 matches the locking block 24. The charging structure 3 includes a positive connection terminal 31, a negative connection terminal 32, a ground connection terminal 33 and an insulating component 34 for isolating the positive connection terminal 31, the negative connection terminal 32 and the ground connection terminal 33. By setting a locking structure and a fixed connection, the connection between the charging gun and the vehicle-end socket is more stable. In this embodiment, a locking structure and a fixed connection are provided to make the connection between the charging gun and the vehicle-end socket more stable. At the same time, the reset spring of the reset member 25 is a small coil spring made of cold-rolled spring steel wire material, which has good ductility and reasonable cost. Of course, the reset spring is not limited to a small coil spring made of cold-rolled spring steel wire material, but may also be other forms as long as it can achieve the reset effect.

[0032] Specifically, Figure 4 As shown, an insulating head 4 for preventing electric shock is provided at the end of the positive connection terminal 31 and / or the negative connection terminal 32. In this embodiment, an insulating head 4 for preventing electric shock is provided at the end of the positive connection terminal 31, and the insulating head 4 is made of plastic material. Of course, an insulating head 4 can also be provided at the end of the negative connection terminal 32, or an insulating head 4 can be provided at the ends of both the positive connection terminal 31 and the negative connection terminal 32. The insulating head can prevent the user from having problems such as electric shock and short circuit during the plugging and unplugging process.

[0033] Specifically, Figure 4 As shown, a thread 5 is provided at the end of the positive connection terminal 31 and / or the negative connection terminal 32, and the insulating head 4 is fixedly connected to the end of the positive connection terminal 31 and / or the negative connection terminal 32 through the thread 5. In this embodiment, a thread 5 is provided at the end of the positive connection terminal 31, and the insulating head 4 is fixedly connected to the end of the positive connection terminal 31 through the thread 5, or a thread 5 is provided at the end of the negative connection terminal 32, and the insulating head 4 is fixedly connected to the end of the negative connection terminal 32 through the thread 5, or a thread 5 is provided at the end of the positive connection terminal 31 and the negative connection terminal 32, and the insulating head 4 is fixedly connected to the end of the positive connection terminal 31 and the negative connection terminal 32 through the thread 5. The insulating head can be fixed more effectively by the thread, and at the same time, the insulating head can be made of PE insulating material, which can better isolate the generation of static electricity and high-voltage arcs. Of course, the material of the insulating head is not limited to PE, and can also be other materials.

[0034] Specifically, Figure 2As shown, the locking structure 2 includes a push button 21, a push block 22, a limit rod 23, a locking block 24 and a reset member 25. The push button 21 is fixedly connected to the push block 22, the push block 22 matches the limit rod 23, the push block 22 matches the locking block 24, and the reset member 25 matches and connects with the locking block 24. In this embodiment, when the external charging gun is connected to the vehicle-end charging socket through the charging structure 3, the push button 21 is pushed upward, and the push block 22 connected to the push button 21 is engaged with the locking block 24 connected to the reset member 25, so that the connection between the charging gun and the vehicle-end socket is more stable.

[0035] Specifically, Figure 2 As shown, the push block 22 is provided with a protruding block 222 for locking the locking block 24. In this example, the protruding block 222 is a square protruding block. The protruding block 222 and the locking block 24 match each other. A limiting groove 221 is provided on the push block 22. The limiting rod 23 is arranged in the limiting groove. The width of the limiting groove 221 is greater than the limiting rod 23. In this embodiment, by setting the limiting groove, the push button 21 is constrained when working, and the locking effect of the card connection can be better exerted, and the range of motion can be more reasonably controlled. Of course, the protruding block 222 is not limited to a square, as long as it can play the same or equivalent role as the square.

[0036] Specifically, the locking block 24 is provided with a second protrusion block 241 for fixing the external charging gun head on the seat body. In this example, the second protrusion block 241 is a semi-cylindrical protrusion, which can make the locking of the charging gun and the vehicle-end charging socket more secure when interacting, so that the locking structure 2 can reasonably play a locking role. Of course, the second protrusion block 241 is not limited to a semi-cylindrical shape, as long as it can play the same or equivalent role as a semi-cylindrical shape.

[0037] Specifically, a limit groove 221 is provided on the push block 22, and a limit rod 23 is arranged in the limit groove 221. The width of the limit groove 221 is greater than the limit rod 23, so that the movement range of the push button 21 when working is constrained on both sides, and the push block 23 is limited to the most reasonable position, so that it can exert the best locking effect.

[0038] Specifically, the charging structure 3 also includes an insulating component 34 for isolating the positive connection terminal 31, the negative connection terminal 32 and the ground connection terminal 33. In this embodiment, the insulating component 34 is a new "Y"-shaped structure made of PE insulating material, which can more effectively prevent the generation of high-voltage arcs when the new energy vehicle charging socket is plugged in and out of the charging gun. Of course, the insulating component is not limited to PE material, but can also be other insulating materials, as long as it can effectively prevent the generation of high-voltage arcs when the new energy vehicle charging socket is plugged in and out of the charging gun.

[0039] Specifically, the charging structure 3 further includes a signal connection terminal 35. In this embodiment, the signal connection terminal 35 is used to collect relevant signals during the charging process, and can monitor the charging state in real time.

[0040] Working principle: After the user plugs and unplugs the external charging gun head and the charging structure, push the push button upward to fix the locking structure. When charging is completed, push the push button downward and unplug the external charging gun to complete the entire process.
