Description

Gun head bullet is from rifle that charges Technical Field The invention relates to a gun head bullet-separation type charging gun, and belongs to the technical field of charging guns. Background The charging gun is also called a vehicle charging gun and is used for being inserted into an electric automobile to charge, is one of important accessories of a new energy charging pile, and when the charging pile is used, a user only needs to insert the charging gun into a charging port of the automobile and then can charge through operating the charging pile. At present, although the charging speed of a conventional new energy charging pile can be adjusted according to the model and the requirement of an automobile, even in a quick charging mode, the automobile needs to be fully charged or a certain time is needed, and the charging work does not need to be manually operated, so that a driver is very easy to generate a lassitude or forget a charging event to concentrate on other things, and once the charging is finished or the charging time is over or the driver encounters an emergency, the situation that the driver directly drives away to forget to pull out a charging gun is very likely to happen, and because the charging gun is provided with a locking device, when the vehicle drives away, the charging gun cannot be separated from the automobile because the locking device is not unlocked, the charging gun is very easy to damage and even serious safety accidents are very easy to happen. The Chinese patent publication No. CN108718019A discloses a gun head spring-separated charging gun, which comprises a gun body provided with an inner cavity, a plug, a locking piece and a wire harness, wherein the locking piece can be installed on the gun body in a left-right rotating way, the left end of the locking piece is provided with a lock catch and an arc boss which are protruded downwards, the gun body is provided with a sliding block which can slide out of the gun body leftwards, the sliding block is arranged on the right side of the arc boss and is contacted with the arc boss, the gun body is provided with an ejector rod which is horizontally arranged and can slide out of the gun body leftwards, the sliding block is connected with the ejector rod, the gun body is provided with a wedge block which is vertical to the length direction of the ejector rod and slides, the ejector rod is provided with a clamping groove, the wedge block is sleeved with a first spring, the wedge end of the wedge block slides into the clamping groove under the elastic force of the first spring, the gun body is connected with the gun body through a power storage spring, the gun body is provided with a plug sleeve in a sliding way, one end of the pull rope is connected with the wedge block, the other end of the pull rope is connected with the plug sleeve, one end of the plug sleeve is fixedly connected with the plug sleeve, and one end of the plug sleeve is arranged in the inner cavity and is connected with the wire harness. The scheme has the following defects in actual use: The position of the gun head is maintained only by the pre-tightening force of the spring, and if the gun head is touched by external force in the charging process, the gun head is easy to axially retract, so that the charging is interrupted or poor in contact is caused; the fixing structure and the spring-off mechanism work independently, the contradiction of retraction or dragging caused by separation hysteresis due to fixing failure is easy to occur, and the failure rate is obviously increased under the low-temperature or high-humidity environment. Disclosure of Invention In order to solve the technical problems, the invention provides a gun head spring-off type charging gun, which realizes the functions of quick separation, equipment protection and wire protection when a vehicle is driven away by mistake through the cooperation of an ejection assembly and an electromagnetic technology, a multistage buffering protection structure and a wire elastic constraint design. The technical scheme adopted for solving the technical problems is as follows: the utility model provides a rifle head bullet is from rifle that charges, includes the rifle head casing, the rear end of rifle head casing is provided with the grab handle, the rear end of grab handle is provided with the base, the front side of rifle head shells inner wall has the plug through a plurality of sliders sliding connection, the rear end of plug is connected with flexible connecting wire, flexible connecting wire's tip is provided with control module, control module's rear side is provided with the electric wire, be provided with ejecting subassembly between rifle head casing and the control module, the periphery side of rifle head casing is provided with protective component, when the vehicle is driven off and the rifle that charges does not pull out make plug and vehicle quick separation protective component protect t
