The second sleeve 160 includes a fastening end 161 and a fixing end 162, the fixing end 162 is used for fixing with the second connector 170, and the fastening end 161 is used for fastening with the first assembling portion 410.

A prefabricated hole 163 is formed in the inner wall of the engaging end 161, a limiting member 164 is disposed inside the prefabricated hole 163, and the limiting member 164 is used for being matched with the sliding rotating portion 432; the limiting member 164 has an extending end 1641 extending to the inner side of the second sleeve 160, and the extending end 1641 has a freedom to move along its own axis.

The length of the extension end 1641 is greater than the length of the second end relative to the inner wall of the engaging end 161 and less than the length of the sliding rotation portion 432 relative to the inner wall of the engaging end 161.

The outer surface of the first sleeve 420 is provided with a crescent-shaped projection 421, the inner arc length of the crescent-shaped projection 421 is smaller than the outer diameter of the sliding rotating part, and the height of the crescent-shaped projection is the same as the outer diameter of the first end of the connecting part.

The first sleeve 420 can rotate about its axis under the control of the first controller to slidably and rotatably engage the crescent 421 with the extension 1641.

Referring to fig. 14 and 15, the limiting member 164 is a telescopic structure, and the extending end 1641 of the limiting member 164 has a tapered cross section along the axial direction thereof; the extension end 1641 is composed of a plurality of telescopic tubular structures which are connected end to end from large to small, a first sensitive component 1642 is arranged on the tubular structure at the tail end of the extension end 1641, a second sensitive component 1643 is arranged inside the clamping end 161, and the first controller is in communication connection with the first sensitive component 1642 and the second sensitive component 1643 respectively.

When the first sensitive component 1642 and the second sensitive component 1643 are located at the same level, the first sensitive component 1642 and the second sensitive component 1643 send feedback signals to the first controller. It is understood that the limiting member 164 of the present invention can have various structures, and it can also be movably disposed inside the second sleeve as long as it can be ensured that the limiting member has the engaging end 161 that is connected to the inner wall of the second sleeve, and the engaging end 161 is used for fixing the limiting member 164, further, as long as it can be ensured that the end of the extending end 1641 of the limiting member can contact and slide along the outer edge of the first sleeve during the rotation of the first sleeve. Due to the length limitation of the extension end 1641, when the crescent-shaped protrusion on the outer edge of the first sleeve 420 contacts, the end of the extension end 1641 moves vertically upward along the axial direction thereof under the interference force of the crescent-shaped protrusion, the top point of the upward movement is the highest point of the outer edge of the crescent-shaped protrusion, at this time, the limiting member 164 cannot limit the first assembling portion 410, and the first assembling portion 410 can move along its own axis, i.e., can be separated from the second assembling portion 150 at this time. At this time, the first sensitive component 1642 and the second sensitive component 1643 at the end of the extension end 1641 are connected in communication with each other to send a feedback signal, and the feedback signal can be sent by any component. The limiting member 164 of the present invention may be a retractable structure, a foldable structure, or a vertically movable structure. The structure, size and shape of the limiting member 164 of the present invention can be set at will, and those skilled in the art can make changes to the structure and size of the limiting member while ensuring the movement principle of the limiting member, which are within the protection scope of the present invention. Moreover, the first sensitive component 1642 and the second sensitive component 1643 may be implemented by using a known technology, such as an infrared sensor, a photosensitive element, a displacement sensor, and the like, and the specific structure thereof may be flexibly selected, so long as the first sensitive component 1642 and the second sensitive component are configured to send a signal when the first sensitive component 1642 and the second sensitive component are butted, or continuously send a signal, when the first sensitive component and the second sensitive component are in communication connection, the first controller does not send a signal any more, and the first controller can know whether the first assembly portion can be separated from the second assembly portion by detecting the abnormality of the signal of the sensitive component.

It can be understood that, when the first assembling portion 410 of the present invention extends and moves along the direction of the second assembling portion 420, the connecting portion 433 can enter the second sleeve 170 in advance, at this time, because the connecting portion 433 is wedge-shaped, the extending length of the extending end 1641 of the limiting member 164 can be reduced, that is, the connecting portion 433 can push the extending end 1641 to fold, contract or move upward while advancing in the process of contacting with the end of the extending end 1641. When the connecting portion 433 moves to the left side of the limiting member 164, the sliding rotation portion 432 is located right below the extension end 1641, because the outer diameter of the sliding rotation portion 432 is smaller than the outer diameter of the first end of the connecting portion, the extension end 1641 moves downward due to gravity, and after the extension end 1641 falls, the sliding rotation portion 432 forms a limiting groove of the first plug 430. At this time, the first assembling portion is electrically connected to the second assembling portion, and the battery 500 can supply power to the charging gun 200. When the battery 500 is low, the first connection signal sends the detected signal to the first controller, and after the first controller receives the signal, the first sleeve is driven to rotate around the axis of the first sleeve, so that the crescent-shaped projection 421 rotates to a position right above the first plug connector along the radial direction of the first plug connector, in the rotating process of the crescent-shaped projection 421, the tail end of the extension end 1641 is always in sliding fit with the outer edge of the crescent-shaped projection 421, and moves upward along the axis direction under the action of the crescent 421, at this time, the position-limiting member 164 cannot limit the position of the first plug, and can send a feedback signal to the first controller, the first controller drives the telescopic part to retract along the direction of the battery storage compartment 400 after receiving the feedback signal, at the moment, the first plug connector is disconnected with the second plug connector, the battery 500 in the battery storage compartment 400 cannot continue to charge the charging gun 200.

The batteries 500 automatically drop onto the output track 121 after exiting the battery storage compartment 400 and pass through the output track 121 to the output port 120.
