[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "circumference" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0026] At present, after new energy vehicles are charged with a charging gun, they are manually unplugged. However, since the charging gun and the socket are tightly plugged together, there is a large friction force, and personnel need to use a large force to unplug the charging gun, which is inconvenient to operate. In addition, if the charging gun is in an inclined state relative to the socket hole during the unplugging process, the greater the force used to unplug the charging gun, the more likely it is to cause the charging gun or the socket to be skewed or damaged, affecting the service life of the charging gun and the socket. Based on this, this embodiment provides a charging gun that is easy to unplug.

[0027] Embodiment 1

[0028] See also Figure 1-Figure 2 The charging gun shown includes a shell 1, one end of which is provided with a plug-in terminal 101 for docking with a socket, and the end face of the plug-in terminal 101 is provided with a plurality of plug interfaces. The plug-in terminal is aligned with the charging socket of the car and pressed hard to plug it in, thereby completing the docking of the charging gun and the socket.

[0029] like Figure 2 and Figure 3 As shown, in order to remove the charging gun from the socket, three push rods 2 are slidably arranged in the plug end 101, and the push rods 2 can extend out of the end face of the plug end 101, and the three push rods 2 are arranged at the edge of the end face of the plug end 101 in a triangular structure, that is, avoiding the plug interface and ensuring the stability of the structure. Of course, other numbers and positions of push rods can also be arranged according to various structures of the plug interface.

[0030] In this embodiment of the present invention, please refer to Figure 3 and Figure 4 As shown, a mounting block 3 is provided to ensure the consistency of the operation of the three push rods 2, and the inner ends of the three push rods 2 are fixedly connected to a surface of the mounting block 3. Among them, a plurality of holes are opened on the mounting block 3 to facilitate the wiring requirements in the gun.

[0031] See also Figure 3 and Figure 4 As shown, in order to drive the push rod 2 to move, a handle 5 is provided on one side of the housing 1, and the handle 5 is connected to the mounting block 3 through a gear set. Specifically, a first gear 6, a second gear 7 and a third gear 8 are rotatably installed in the housing 1. One end of the handle 5 is hinged to the inner wall of the housing 1, and a notch adapted to the handle 5 is provided on the lower side of the housing 1, so that the other end of the handle 5 can be inserted into the housing 1 and can rotate around the hinge point. The end of the handle 5 extending into the housing 1 adopts an arc structure, and a tooth block is provided on the inner side of the arc structure, so that the end can mesh with the second gear 7. In addition, the second gear 7 meshes with the third gear 8, and the third gear 8 meshes with the first gear 6. A driving rod 4 is provided between the third gear 8 and the mounting block 3, one end of the driving rod 4 is hinged to the edge of the first gear 6, and the other end of the driving rod 4 is hinged to the mounting block 3.

[0032] After charging is completed, pinch the handle 5 into the housing 1, the handle 5 drives the second gear 7 to rotate, the second gear 7 drives the first gear 6 to rotate through the third gear 8, and the first gear 6 pushes the drive rod 4 forward, thereby pushing the push rod 2 out of the end face of the plug end 101 and pressing it against the plane around the socket, so that the plug end 101 is withdrawn from the socket, that is, the charging gun is pulled out of the socket. The entire unplugging operation is simple and labor-saving. At the same time, it can ensure that the charging gun is parallel to the socket during the unplugging process, avoiding the skewness and damage of the charging gun and the socket.

[0033] Based on the above design, the diameter of the first gear 6 is preferably larger than that of the second gear 7 and the third gear 8. It is more labor-saving to drive the large gear to rotate by the small gear, so as to facilitate squeezing the handle 5 to push the push rod 2 out.

[0034] Embodiment 2

[0035] Based on the first embodiment, the improvement of the second embodiment is:

[0036] See also Figure 5As shown, an elastic member is also designed to drive the three push rods 2 to reset. Specifically, the elastic member is a spring 9, one end of which is fixedly connected to the handle 5, and the other end of which is fixedly connected to the housing 1. When the handle 5 is pressed, the spring 9 is stretched, and when the handle 5 is released, the spring 9 recovers its deformation, driving the handle 5 to reset, thereby driving the gears to rotate in the opposite direction and retracting the push rods 2 into the gun.
