Rifle cooperation charging socket charges, and to prevent charging gun from surprisingly falling off in charging, needs that electronics is arranged on charging socket
Lock is to carry out locking, but electronic lock is after a number of uses, and there is abrasions and meaning for the lock tongue on charging gun locking mouth and electronic lock
The case where outer fracture, so that the charging socket that charging gun can effectively be locked at electric car in charging cannot be effectively ensured
On, it is therefore necessary to design a kind of detection device to detect its locking situation, prevent unexpected generation.
Summary of the invention
The present invention, can be effectively to electronic lock in view of this, provide a kind of detection device of charging socket electronic lock
Lockup state detected, can be sounded an alarm in time after detecting abnormal conditions, avoid that accident occurs.
A kind of detection device of electronic lock is located in electronic lock, and detection device has microswitch, the fixed peace of microswitch
Mounted in electronic lock inner wall, microswitch is tightly attached to the side of lock tongue posterior segment, and the lock tongue rear end has the protrusion of arc,
Microswitch is located at the front of arc convex when uncharged, and in charging, microswitch is located at the back upper place of arc convex；If lock
The movement travel of the nose wear of tongue or fracture, lock tongue becomes larger, and microswitch is located at the rear of arc convex.
The leading portion of lock tongue has positioning convex platform, and positioning convex platform height is lower than the tip of the tongue of lock tongue, for pushing against the outer wall of socket
It is positioned.
The microswitch is connected on micro-tremor signal circuit, and microswitch is in parallel with resistance R1, and is gone here and there with resistance R2
Detection device is accessed in one end of microswitch and resistance R1 by connection, and the other end of resistance R2 also accesses corresponding in detection device
Interface.
The resistance value of resistance R1 is greater than the resistance value of R2.
Microswitch is normally closed switch.
When in use, will equipped with detection device charging gun insertion electric car socket on, if the leading portion of lock tongue or
Charging gun locking hole does not damage, and microswitch is located at the back upper place of arc convex, and microswitch is in the open state, micro-tremor signal
The resistance value of circuit is the resistance value of R1+R2；If the leading portion or charging gun locking hole of lock tongue damage, microswitch is located at arc
The rear of protrusion, microswitch are in closed state, and the resistance value of micro-tremor signal circuit is the resistance value of R2；Detection device passes through
The resistance value of detection micro-tremor signal circuit can determine whether the lock tongue of electronic lock wears or be broken.
Present inventive concept is ingenious, structure is simple, easy to use, can accurate judgement by the closed state of microswitch
The leading portion of lock tongue whether excessive wear or fracture, and judge whether the working condition of electronic lock good by the size of resistance value in turn
Good, the present invention has good value for applications.
