[0029] A charging gun 2 is provided on the outside of the charging pile body 1, and an auxiliary module 3 is fixedly connected to the side of the charging pile body 1. The left and right sides of the auxiliary module 3 are embedded with the driving module 4, and the inner side of the driving module 4 is embedded with the motor 10, and one side of the motor 10 is embedded with the transmission shaft 11, and the other end of the transmission shaft 11 is fixedly connected with the first rotating wheel 7, and the lower end of the transmission shaft 11 is provided with a rotating shaft 13, and one end of the rotating shaft 13 is fixedly connected with the second rotating wheel 8, and the other end of the rotating shaft 13 is movably connected to the inner wall of the auxiliary module 3, and the other end of the second rotating wheel 8 is fixedly connected to the positioning shaft 12, and the other end of the positioning shaft 12 is movably connected to the inside of the auxiliary module 3, and the left and right sides of the charging gun 2 are fixedly connected with the slide groove 5, the positioning shaft 12 is rectangular as a whole, and the side of the positioning shaft 12 close to the charging gun socket 9 is an arc that fits the arc of the charging gun socket 9, and the charging gun socket 9 is arranged on the inner side of the auxiliary module 3, which makes the inner wall of the auxiliary module 3 The upper and lower ends of the inner center of the slide groove 5 are provided with grooves, and the groove at the upper end is fixedly connected to the slide groove 5. The groove surface at the bottom of the slide groove 5 is a smooth glass surface. When the user uses the present device for charging, the user can hold the handle on the outside of the charging gun 2 and then pull out the charging gun 2. In this process, the charging gun 2 will start the motor 10 when it moves outward, and then the motor 10 drives the first rotating wheel 7 to rotate through the transmission shaft 11, so that the first rotating wheel 7 rubs the friction pad 6 on the groove surface at the upper end of the slide groove 5. Through this design, the first rotating wheel 7 can drive the slide groove 5 to move, and then the charging gun 2 moves outward, thereby playing a role in assisting the user to pull out the gun. In the process of the first rotating wheel 7 rotating to move the slide groove 5, the second rotating wheel 8 abuts against the groove at the bottom of the slide groove 5 at the bottom to provide a support point to prevent the slide groove 5 from tilting during movement.

[0030] A charging gun socket 9 is provided on the inner side of the auxiliary module 3, and a limit ring 14 is fixedly connected to the inner wall of the charging gun socket 9, a charging gun limit ring 15 is fixedly connected to the outer side of the charging gun 2, and a separation groove 16 is embedded in the surface of the slide groove 5. After the user has finished using the device, the user can insert the charging gun 2 into the inner side of the auxiliary module 3, and then push the charging gun 2 in. In the process of pushing the charging gun 2, the motor 10 starts to drive the first rotating wheel 7 to rotate and retract the charging gun 2. In this process, when the charging gun 2 is retracted to the specified position, The charging gun limiting ring 15 on the surface of the charging gun 2 will abut against the surface of the limiting ring 14 on the inner side of the auxiliary module 3, thereby limiting the charging gun 2 as a whole, and at the same time, the separation groove 16 on the upper surface of the slide groove 5 will move to the bottom of the first rotating wheel 7, so that the first rotating wheel 7 is separated from the slide groove 5, avoiding the situation that after the charging gun limiting ring 15 abuts against the surface of the limiting ring 14, the first rotating wheel 7 still abuts against the surface of the friction pad 6 in the groove on the slide groove 5, avoiding the first rotating wheel 7 from excessively rubbing against the surface of the friction pad 6 to reduce the friction between the first rotating wheel 7 and the friction pad 6.

[0031] A friction pad 6 is fixedly connected to the surface of the slide groove 5 , and the contact surface between the friction pad 6 and the first rotating wheel 7 is provided with anti-skid grooves. Through this design, the friction force between the friction pad 6 and the first rotating wheel 7 is enhanced.

[0032] A separation groove 16 is provided at the center of the upper and lower grooves of the slide groove 5, and the separation groove 16 of the upper groove is embedded in the surface of the friction pad 6. When the charging gun limit ring 15 abuts against the surface of the limit ring 14, the first rotating wheel 7 and the second rotating wheel 8 are separated from the contact between the slide groove 5 through the upper and lower separation grooves 16 of the slide groove 5 respectively.

[0033] A protective frame is provided on the outside of the motor 10, and the protective frame is fixedly connected to the inner wall of the driving module 4. The motor 10 is an induction motor, which has a self-starting function. When the user pulls out or inserts the charging gun 2, the friction pad 6 in the groove on the upper surface of the slide groove 5 will drive the first wheel 7 to rotate through friction, and then the first wheel 7 drives the rotor inside the motor 10 to rotate through the transmission shaft 11, so that the rotor inside the motor 10 generates an induced current. The induced current generates a magnetic field on the rotor, which interacts with the stator magnetic field of the motor 10, so that the motor generates torque, thereby starting the motor 10. At the same time, in this process, the rotation direction of the rotor after the motor 10 is started will be determined according to the rotation direction of the first wheel 7.

[0034] Working principle: When the user uses the device to charge, the user can hold the handle on the outside of the charging gun 2 and then pull out the charging gun 2. During this process, the charging gun 2 will start the motor 10 when it moves outward. The motor 10 is an induction motor with a self-starting function. When the user pulls out or inserts the charging gun 2, the friction pad 6 in the groove on the upper surface of the slide 5 will drive the first wheel 7 to rotate through friction, and then the first wheel 7 drives the rotor inside the motor 10 to rotate through the transmission shaft 11, so that the rotor inside the motor 10 generates an induced current. The induced current generates a magnetic field on the rotor, which interacts with the stator magnetic field of the motor 10. The motor generates torque, thereby starting the motor 10. During this process, the rotation direction of the rotor of the motor 10 after starting is determined according to the rotation direction of the first wheel 7. Subsequently, the motor 10 drives the first wheel 7 to rotate through the transmission shaft 11, so that the first wheel 7 rubs against the friction pad 6 on the surface of the groove at the upper end of the slide 5. Through this design, the first wheel 7 can drive the slide 5 to move, and then move the charging gun 2 outward, thereby assisting the user in drawing the gun. In the process of the first wheel 7 rotating and moving the slide 5, the second wheel 8 rests on the bottom groove of the slide 5 to provide a support point, thereby preventing the slide 5 from tilting during movement.

[0035] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.

[0036] In the description of the present invention, it is necessary to understand that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
