Description

Self-disengaging control socket and charging device Technical Field The present disclosure relates to charging connectors, and particularly to a self-releasing control socket and a charging device. Background According to the electric equipment of many automobiles, such as emergency vehicles like fire trucks and ambulances, and meanwhile, many hybrid electric vehicles or pure electric vehicles are present, the electric equipment needs to be charged. At present, when the charging equipment such as the fire-fighting vehicle works, when the fire-fighting vehicle emergently gives an alarm, the charging auxiliary line connected with the fire-fighting vehicle can be automatically separated from the vehicle after the vehicle is started, so that the alarm time can be accelerated as much as possible. Emergency vehicles such as ambulances have similar problems. And electric automobile also has sometimes to forget that the car just directly starts the traveling still being charged to lead to charging plug and charging socket to damage, there is great potential safety hazard. The automatic charging device that breaks away from in present market, like application number "2015207852981", patent name "an automobile-used automatic charging controller that breaks away from", this kind of structure, in the charging process, need to hook the rifle that charges through the socket cover for prevent that elasticity energy storage mechanism from ejecting the rifle that charges, exist following not enoughly: 1. The plug is provided with the boss matched with the socket cover plate independently, but in practice, a plurality of charging guns are not provided with the boss, so that the suitability is limited, and the application range is smaller; 2. The socket cover plate is generally made of plastic parts, and when the socket cover plate of the plastic parts is charged, the socket cover plate is subjected to external force of the charging gun for a long time, so that the socket cover plate is easy to damage. 3. When the barbs of the socket cover plate and the bosses of the socket are separated, the friction force of the barbs and the bosses is large, and the situation that the barbs cannot be separated from the bosses possibly occurs, so that the plug cannot be normally separated and controlled, and the socket cover plate is broken and damaged when a subsequent automobile is opened; 4. When the barb of socket apron breaks away from with the boss of socket, both frictional forces are great, and the time is a long, and more wearing and tearing can appear in the junction of couple and boss, and then lead to the grafting of plug and socket not inseparable enough, influence the stability of charging. Disclosure of Invention The utility model aims to provide an automatic-release control socket and a charging device, which improve the stability and smoothness of automatic release control and improve the application range by using the structure. In order to achieve the purpose, the technical scheme adopted by the utility model is that the self-disengaging control socket comprises: the socket comprises a socket main body, wherein a socket body which is in plug-in fit with a plug is arranged in the socket main body; the plug ejection mechanism is arranged in the socket body and comprises a push rod and a push rod pushing part, and the push rod pushing part has self-resetting force for pushing the push rod from the plugging position to the disengaging position; The ejector rod limiting part is arranged in the socket main body and comprises a limiting part movably arranged on the socket main body and a limiting part driving part for driving the inner end of the limiting part to be close to or far away from the ejector rod; the ejector rod is provided with a matching part matched with the inner end of the limiting part, and when the ejector rod is in the plugging position, the limiting part driving part can drive the inner end of the limiting part to be close to the ejector rod and matched with the matching part, and limit the ejector rod to move forwards; When the inner end of the limiting part is driven by the limiting part driving part to be far away from the ejector rod and separated from the matching part, the ejector rod pushing part pushes the ejector rod to move forwards to a separation position. In the above technical scheme, the limiting piece driving part comprises an electromagnet and a limiting piece pushing part, the electromagnet gives the pulling force of the limiting piece away from the ejector rod, and the limiting piece pushing part gives the pushing force of the limiting piece moving towards the ejector rod. In the technical scheme, the limiting piece is arranged beside the ejector rod, the limiting piece is arranged between the electromagnet and the ejector rod, and the electromagnet is connected with the outer end of the limiting piece through the intermediate transmission part. In the above technical scheme, the middle tr
