[0036] 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 technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] An electric car discharge gun, such as Figure 1-Figure 5 As shown, it includes: a discharge gun body 1, a connecting piece 2 and a spring 3;

[0038] The discharge gun body 1 is provided with a mounting groove 11, and the connecting member 2 is at least partially located in the mounting groove 11;

[0039] The connecting member 2 includes a pressing end 21, a connecting end 22 and a locking end 23 connected in sequence;

[0040] Mounting holes 111 are provided on both sides of the mounting slot 11, and connecting shafts 112 are provided on the mounting holes 111;

[0041] The connecting end 22 has a connecting hole 221, and the connecting member 2 is hinged to the connecting shaft 112 through the connecting hole 221.

[0042] At least one of the mounting holes 111 is in communication with the side wall of the discharge gun body 1;

[0043] The pressing end 21 includes a mounting post 211;

[0044] The spring 3 is sleeved on the mounting post 211, with one end connected to the discharge gun body 1 and the other end supporting the pressing end 21;

[0045] The locking end 23 has a locking hook 231 .

[0046] One end of the discharge gun is connected to the electric vehicle, and the other end is used to connect the socket of the electrical appliance. To keep the appliance in use, the discharge gun body 1 needs to be stably connected to the charging seat 4 through the connector 2 to keep discharging. The connector 2 is hinged to the discharge gun body 1 through the connecting shaft 112. The connecting shaft 112 is fixed in the mounting hole 111. The mounting hole 111 is connected to the discharge gun body 1. In this way, the connecting shaft 112 can be installed into the mounting hole 111 from the side of the discharge gun body 1 and has an interference fit with the mounting hole 111, thereby achieving convenient and quick installation. Alternatively, the side wall of the discharge gun body 1 can be blocked to prevent the connecting shaft 112 from falling off. When in use, press the pressing end 21, the spring 3 is compressed, and the lock hook 231 of the locking end 23 is lifted, moving the discharge gun body 1 forward so that the lock hook is engaged with the lock port 41 of the charging seat 4, thereby achieving the connection between the discharge gun body 1 and the charging seat 4.

[0047] In some embodiments, a PVC film 5 is provided on the discharge gun body 1, and the PVC film 5 covers the mounting hole 111. The PVC film 5 can shield the mounting hole 111, making the appearance of the discharge gun more uniform.

[0048] In some embodiments, the pressing end 21 is provided with an anti-slip pattern for pressing. The anti-slip pattern can increase friction and facilitate the user to press.

[0049] In some embodiments, the connector 2 has a recessed portion 24, and the mounting post 211 is at least partially located within the recessed portion 24. Providing the recessed portion 24 on the connector 2 and arranging the mounting post 211 within the recessed portion 24 can reduce the volume of the connector 2, making the structure more compact, and also reducing weight and cost.

[0050] Furthermore, a reinforcing rib 25 is provided in the recessed portion 24. The reinforcing rib can support the connector 2 and ensure the overall strength of the connector 2.

[0051] In some embodiments, the reinforcing ribs 25 include first reinforcing ribs 251 along the extending direction of the connector and second reinforcing ribs 252 perpendicular to the first reinforcing ribs 251. The first reinforcing ribs 251 and the second reinforcing ribs 252 cooperate to support the connector 2 from all angles.

[0052] In some embodiments, the connector 2 is made of PA6-GF30. PA6-GF30 is a high-performance engineering plastic composed of polyamide 6 (PA6) and glass fiber reinforcement (GF30). It has high rigidity, high strength, heat resistance, and wear resistance, ensuring the service life of the connector 2.

[0053] The present application also provides a connection structure between a discharge gun and a charging base, such as Figure 6 As shown, it includes the electric vehicle discharge gun and the charging base 4 as described above. The charging base 4 includes a charging interface 42. There is a lock hole 41 above the charging interface 42. The lock hook 231 extends into the lock hole 41 to prevent the discharge gun body 1 from separating from the charging base 4.

[0054] Furthermore, the charging station 4 has an electronic lock 43, and the locking rod 431 of the electronic lock 43 extends to prevent the locking hook 231 from escaping from the locking port 41. After the locking hook 231 is engaged with the locking port 41, the locking rod 321 of the electronic lock 43 extends above the locking hook 231, making it impossible to lift the locking hook 231, thereby preventing the locking hook from falling off and ensuring discharge safety.

[0055] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
