[0025] In order to make the personnel in the technical field better understand the utility model scheme, the technical scheme in the utility model embodiment will be described clearly and completely below in combination with the drawings in the utility model embodiment.

[0026] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0027] The following is in conjunction with the appendix Figs. 1-3 The present invention will be described in further detail below.

[0028] Reference Figs. 1-3 A charging gun includes: a gun body 1, an adaptive adjustment component and a connector 2, wherein one end of the gun body 1 is configured as a charging plug interface and the other end is a connection end face;

[0029] The adaptive adjustment component includes a first connecting ring 3, a second connecting ring 4, and an elastic body 5. The elastic body 5 is disposed between the first connecting ring 3 and the second connecting ring 4. The first connecting ring 3 is connected to the connecting end face, and the second connecting ring 4 is connected to the connector 2.

[0030] Connector 2 is used to connect to the robot arm.

[0031] Based on the above structure, during use, the gun body 1 is fixed to the robot arm through the connector 2. The robot uses image recognition to insert one end of the charging plug into the charging port. When there is a certain error between the charging plug and the charging port (the end of the charging plug has already entered the charging port), since the gun body 1 and the robot arm are connected by an elastic body 5, the charging gun can move relative to one end of the robot arm (the elastic body 5 deforms), so that the charging gun has an adaptive function and avoids forcibly inserting and damaging the vehicle or the charging gun.

[0032] A further optimization is that, in order for the elastomer 5 to adapt to deformation, the elastomer 5 can be made of rubber, and as... Fig. 3 As shown, the elastomer 5 is preferably annular, and most preferably flared, so that the elastomer 5 can deform under less force and the amount of material used is reduced.

[0033] like Fig. 2 As shown, in order to stably fix the gun body 1, the adaptive adjustment component and the connector 2, flanges 7 are provided on the sides of the first connecting ring 3 and the second connecting ring 4 that are close to each other. The two flanges 7 are fixed to the connecting end face and the connector 2 respectively by screws. This facilitates assembly and disassembly and reduces production assembly costs.

[0034] like Fig. 2As shown, in order to facilitate the screwing of the screw on the first connecting ring 3, the first connecting ring 3 is connected to the larger opening end of the elastic body 5, so that the size of the first connecting ring 3 is larger than the second connecting ring 5 and the connecting piece 2, so that the second connecting ring 5 and the connecting piece 2 do not block the screw head on the first connecting ring 3, so as to facilitate the screwing of the screw and improve the production and assembly efficiency.

[0035] Further optimization is that in order to facilitate the robot to take the gun body 1, the connecting piece 2 is made of magnetic material, so that the connecting piece 2 is fixed by the electromagnet assembly (with magnetism when powered on and lose magnetism when powered off) on the robot arm, realizing the taking of the gun body 1; and the ring side of the connecting piece 2 is provided with a plurality of connecting lugs 21, which can also be used to fix or hang the gun body 1 through bolts.

[0036] As shown, Fig. 2 The connecting piece 2 is provided with a switch 6, the end of the switch 6 protrudes from the end of the connecting piece 2 away from the adaptive adjusting piece, the switch 6 is a power-on switch, when the gun body 1 is completely connected with the vehicle charging port, the switch 6 will be closed, realizing charging, and when the gun body 1 is not completely inserted or disconnected from the vehicle charging port, the switch 6 remains open, realizing power-off.

[0037] Further optimization is that in order to reduce production cost and improve assembly efficiency, the first connecting ring 3, the second connecting ring 4 and the elastic body 5 are integrally injection molded.

[0038] In summary, in use, the gun body 1 is fixed on the robot arm through the connecting piece 2, the robot identifies the image and inserts one end of the charging plug interface to the charging port, when there is a certain error between the charging plug interface and the charging port, because the gun body 1 is connected with the robot arm through the elastic body 5, the charging gun can move relatively at one end of the robot arm, so that the charging gun has the function of self-adaptation, avoiding damage to the vehicle or the charging gun by forced insertion.

[0039] The specific embodiment is only an explanation of the application, which is not a limitation of the application, and those skilled in the art can make modifications to the embodiment without creative contribution after reading the specification, but as long as it is within the scope of the claims of the application, it is protected by the patent law.
