Description
Technical Field
The utility model belongs to the technical field of fill electric pile technique and specifically relates to indicate an anti-lock rifle that charges.
Background
With the popularization of electric vehicles, charging equipment is increasingly widely applied, and new technical problems derive along with the popularization of electric vehicles, wherein locking control of a charging gun is a new technical problem. In the new national standard "GB/T18487.1-2015 general requirements for conductive charging system for electric vehicles part 1", it is explicitly required that the charging gun or the charging socket have an electronic locking function. The most common realization mode of electronic locking is to use an electromagnet, and then control a lock hook of a charging gun by controlling a lock cylinder of the electromagnet so as to achieve the purpose of controlling a mechanical locking mechanism by the electronic lock.
In the currently generally adopted electromagnet locking mechanism, a charging gun locking hook is a lever, the front end of the charging gun locking hook falls into a clamping groove of a charging socket, an elastic arm of a locking hook position switch (normally closed) is in a release state at the moment, and a charging pile confirms that charging connection is reliable and then carries out next operation, namely a locking state; press the end of latch hook, latch hook depressor latch hook position switch's elastic arm, the switch becomes the disconnection by the closure, fills electric pile detection and learns to fill and connect unreliable then the interrupt to charge, presses the end of latch hook simultaneously and can lift up the front end pothook, and the pothook breaks away from the socket draw-in groove, promptly for the unblock state. An electromagnet for electronic locking is placed at the tail end of the locking hook, when a lock cylinder of the electromagnet extends out, the lock cylinder prevents the tail end of the locking hook from moving downwards, the locking of the locking hook cannot be unlocked, and the locking hook cannot be manually pressed down to cause charging interruption in the charging process; when the charging is finished and the electromagnetic lock cylinder retracts, the tail end of the lock hook can be pressed, and then the locking can be released. The GBT 18487.1-2015 also provides that the electronic lock has a locking position feedback function, and in practice, a position switch is usually placed at the end of the lock cylinder of the electromagnet, so that the charging pile can recognize whether the electromagnet is in a locking state or an unlocking state, and when the charging pile recognizes that the electromagnet is not reliably locked or unlocked, a fault signal can be sent out to stop charging or stop charging. The purpose of controlling the locking mechanism can be achieved by controlling the electromagnet.
The electronic lock with the structure has a prominent disadvantage that after the charging gun is charged, the charging pile supplies power to the electromagnet to control the return of the lock cylinder of the electromagnet, but if the lock cylinder is pressed by the lock hook in the return process, the lock cylinder cannot return; the electromagnetic lock cylinder is characterized in that a magnetic latching electromagnet (or called pulse electromagnet) is generally adopted at present, the electromagnet has the advantages that the lock cylinder extends out and retracts by means of pulse power supply signals, the electromagnet does not need to be continuously powered in an extending state (namely, a locking state), the service life of the electromagnet is prolonged, and instant current can be designed to be large due to the fact that the power supply signals are pulse, and therefore the driving force of the lock cylinder is guaranteed; the defect is obvious, the power supply signal given by the charging pile is instantaneous, the power supply signal cannot be sent out, and when the lock cylinder is pressed again, the lock cylinder cannot return; once the electro-magnet can not retract the lock core, because latch hook and lock core direct contact are blocked in the lock core position, can't be pressed to can't untie the locking, also can't pull out the rifle, in particular in the emergency of the trouble that charges, this kind of situation is especially dangerous.
In order to prevent the abnormal separation between the charging gun and the vehicle when the charging gun is in a use state and protect the personal safety of a user, the charging gun body of the charging gun is provided with a touch switch to achieve a certain protection function. As shown in fig. 1, the touch switch includes an electromagnetic lock 3 and a lock link 2, the middle of the lock link 2 is hinged to the charging gun body 1 through a hinge 22, and the front end of the lock link 2 is a lock hook 21. In the locked state, the locking hook 21 is locked in the charging gun base 7, and the lock cylinder 31 of the electromagnetic lock 3 extends out to clamp the rear end of the lock connecting rod 2 and cannot rotate downwards around the hinge part 22. In the unlocking state, the lock cylinder 31 of the electromagnetic lock 3 retracts into the electromagnetic lock 3, and the rear end of the lock link 2 can rotate downwards around the hinge part 22, so that the lock hook 21 is separated from the charging gun seat 7. After the lock connecting rod rotates, the lock connecting rod resets under the action of the spring 6, and the lock connecting rod is prevented from tilting. In the manufacturing process, in order to save electric energy and prolong the service life of the electromagnetic lock 3, a magnetic holding electromagnet, also called a pulse type electromagnet, is used as the electromagnetic lock. This kind of electromagnetic lock, under the state that lock core 31 stretches out, the coil of electromagnetic lock 3 does not switch on, when needing the unblock, can provide a current pulse to electromagnetic lock 3, retracts through instantaneous current drive lock core 31 to realize the unblock. The lock core 31 of the electromagnetic lock 3 can not be retracted normally, the lock core 31 locks the rear end of the lock connecting rod 2, so that the rear end of the lock connecting rod 2 can not be pressed down, the lock hook 21 can not be separated from the charging gun seat 7, and the charging gun can not be pulled out from the automobile. When a user finds that the charging gun cannot be pulled out, the tail end of the lock connecting rod is often pressed with brute force to try to unlock, the pressing force directly acts on the electromagnet lock cylinder at the moment, the lock cylinder is pressed askew under severe conditions due to low strength of the lock cylinder, and even if unlocking is successful, the fault that the electromagnetic lock cylinder cannot normally retract or stretch out often occurs when the charging gun with the pressed askew lock cylinder is used later. Meanwhile, the charging gun cannot be unlocked and pulled out, so that the anxiety of the user can be caused, the user experience is poor, and the maintenance of the damaged charging gun is also an expensive expenditure. It is desirable to equip the charging station with a maintenance person, but this will undoubtedly increase the cost.
