[0024] 2. By providing a protective cover and physical support for the charging gun, the stability of the charging gun during use can be improved, and the impact of the external environment on the stability of the charging gun during use can be reduced, thereby further improving the safety of use.

[0025] 3.

During the charging process, the protective component is automatically moved to the charging position for protection, ensuring timely protection of the charging gun.

[0026] 4. By keeping the charging gun in the covered state after charging is completed, and then resetting the guide assembly to drive the charging gun to move back, and automatically inserting the charging gun back into the charging pile body after resetting, it is avoided that the operator will drop the charging gun on the ground after charging is completed, thereby avoiding the problem of damage to the charging gun and further improving the protection effect.

[0027] 5. By setting the rotating component, the protective component is automatically rotated to the position corresponding to the charging gun during the charging process to ensure the implementation of the protective function. When the charging gun is inserted into the charging pile body, the protective component is supported under the charging gun to avoid the risk of the charging gun falling off the charging pile body due to external force.

[0028] 6. By setting up a charging gun status monitor in the second cover, a close-range, stable environment is created for monitoring the status of the charging gun, which is used to determine the impact of frequency response measures on the charging port. When adverse effects occur, targeted adjustments can be made to the changes in the charging gun to avoid unexpected situations. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] In some embodiments, a telescoping device 49 for automatically releasing the lock on the charging gun 12 by pressing is further provided on the cover plate 1 41 or the cover plate 2 42 , and a notch adapted to the telescoping device 49 is provided on the cover plate 1 41 or the cover plate 2 42 on the same side.

[0050] Working principle:

[0051] Before use: drive the vehicle to the charging site, remove the charging gun 12 on the same side from the charging pile body 10, and then insert it into the charging port.

[0052] When in use: the first step is to start the driving motor 17 to drive the driving wheel 16 to rotate after the charging process is completed. The driving wheel 16 generates a moving force along the path of the navigation rope 14, pushing the seat 13 to move along the path of the navigation rope 14 toward the charging gun 12 being charged.

[0053] In the second step, when moving to a position close to the positioning plate 18, the plug rod 1 25 first contacts the positioning plate 18, and reacts to the piston 1 24 under the action of the travel force. The piston 1 24 injects the medium in the liquid cylinder 1 23 into the liquid cylinder 2 26 through the connecting pipe 29, so that the piston 27 is pressed to push the plug rod 28 to extend. After the plug rod 28 extends, it pushes the connecting frame 21. At this time, the guide ring 31 rotates together on the fixed ring 30 through the clamping plate 32 and the rolling wheel 34, and when it rotates to the notch of the fixed ring 30, the pressure plate 36 drives the guide ring 31 together with the connecting frame 21 to descend through the rebound pressure of the resisting spring 38, so that it rotates to a position close to the charging gun 1. 2 can avoid the side of the charging gun 12 by descending, avoiding the collision between the cover body 1 39 and the cover body 2 40 and the charging gun 12. Then the guide ring 31 rises from the notch as it rotates, allowing the cover body 1 39 and the cover body 2 40 to correspond to the lower side of the charging gun 12. When the positioning plate 18 is at a high position, the sleeve block 15 adjusts the height to adapt by sliding the lifting column 19 on the column rod 20. The charging line 11 is in a drooping state during the charging process. After the sleeve block 15 contacts the positioning plate 18, the distance between it and the charging gun 12 is equal to the distance at the initial position, ensuring the corresponding position of the cover body 1 39 and the cover body 2 40 and the charging gun 12.

[0054] In the third step, as the plug rod 25 contracts, the touch switch on the sleeve block 15 contacts the positioning plate 18, and the rotating motor 48 is started to drive the gear 47 to rotate. The gear 47 drives the cover plate 141 to rotate out of the cover body 2 40 through the engagement with the rack 46, and the cover plate 141 drives the cover plate 2 42 to rotate out of the cover body 1 39 through the connection with the cover plate 2 42. The elastic pad 45 deforms and expands as the cover plates 141 and 42 are rotated out. The two connecting rods 43 adapt to the changes in distance and angle through the rotation between the universal joints 44 and the sliding of the connecting rods 43 on the cover plate 2 42. After the two cover plates 1 41 and the two cover plates 2 42 are fitted, the charging gun 12 is covered.

[0055] After use: After charging is completed, the retractor 49 extends to unlock the lock, and the driving motor 17 drives the driving wheel 16 to rotate and pull the charging gun 12 out of the charging vehicle. During the pulling out process, the spring on the piston 27 rebounds and resets, and the medium is squeezed through the connecting pipe 29 and injected back into the liquid cylinder 1 23. The liquid cylinder 26 is subjected to the spring tension to drive the connecting frame 21 to reset, so that the charging gun 12 rotates until the gun head corresponds to the charging pile body 10, and then the seat 13 is reset as the driving wheel 16 rotates. The charging gun 12 with the seat 13 reset is reinserted into the charging pile body 10, and then after the seat 13 is connected to the charging pile body 10, the rotating motor 48 rotates to drive the cover plate 1 41 and the cover plate 2 42 to expand and reset to the initial state.

[0056] It should be noted that the amplitude control of the structural movement of the present application is achieved by setting up sensors, which is a well-known technology and will not be elaborated here.

[0057] like Fig.10 As shown, an automatic frequency response system applied to the above-mentioned charging pile includes energy facilities, a frequency monitoring module, a control system module, a communication module, a power transmission module, a charging pile and a monitoring and management module.

[0058] The frequency monitoring module is used to monitor the frequency changes of the power grid and transmit the monitored frequency data to the control system.

[0059] The control system module adjusts the power output of the charging equipment according to changes in the grid frequency and the preset response strategy.

[0060] The energy facilities include power grid modules, new energy modules and energy storage modules. When the frequency of the circuit system drops, the energy facilities receive power from the control system module to adjust the output power of the new energy module and release the energy of the energy storage module to provide additional power support to maintain the frequency stability of the power system and achieve coordinated frequency response of the site.

[0061] The communication module communicates with the grid operator and the smart grid system to obtain information on grid frequency changes and receive dispatch instructions and requirements.

[0062] The power transmission module transmits electrical energy from the power grid to the charging pile to meet charging needs.

[0063] The monitoring and management module monitors and manages the operating status of the charging station, including setting a charging gun status monitor in the cover body 2 40. The charging gun status monitor is composed of a number of sensors, which monitor the temperature, sound and other conditions of the charging gun to determine the impact of the frequency response measures on the charging port. When adverse effects occur, targeted adjustments are made to the changes in the charging gun to avoid unexpected situations.

[0064] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
