End is provided with through hole.
The connecting rod 12 of T-shaped microswitch 1 passes perpendicularly through the through hole of horizontal struts 2, and horizontal struts 2 are located under baffle ring 13
Side, the left end of horizontal struts 2 are connected by shaft with the right end of buckle 4, and one end of resetting spring 3 is connected to horizontal struts 2
Lower surface, sliding block 5 are located at the right side of the connecting rod 12 of T-shaped microswitch 1 and, driving perpendicular with the connecting rod 12 of T-shaped microswitch 1
Sliding block 5 moves left and right the lockhole that the left end of sliding block 5 can be made to stretch into or exit 12 bottom of connecting rod in the horizontal direction.
Electronic control system moves left and right in the horizontal direction for control slide block 5, as shown in Fig. 2, specifically including micro-
Controller and the RFID module being connected respectively with microcontroller and electromagnetism parallel execution device.Electromagnetism parallel execution device is installed on sliding block
On 5, moved left and right for the order-driven sliding block 5 according to microcontroller.RFID module is used to receive magnetic card signal, and to micro-
Controller forwards the magnetic card signal.
When microcontroller receives the charging signals of automobile power system, micro-controller instructions electromagnetism parallel execution device band
Movable slider 5 is moved to the left, and the left end of sliding block 5 is stretched into lockhole, and T-shaped microswitch 1 can not act, and mechanical lock unit is in lock
Death situation state.
When microcontroller receives magnetic card signal, micro-controller instructions electromagnetism parallel execution device band movable slider 5 moves right
It is dynamic, the left end of sliding block 5 is exited lockhole, T-shaped microswitch 1 can act, and mechanical lock unit is in can unlocking condition.
Since in extreme low temperature environment, electromagnetism parallel execution device can lead to not work because of its magnetism decline, thus, this
Mechanical lock unit further includes emergency stop knob 6 and emergency stop bar 7.Emergency stop bar 7 is vertically connected at the lower surface of sliding block 5, emergency stop knob 6
The front of emergency stop bar 7 is installed on, the driving that emergency stop knob 6 specifically includes rotation axis 61 and rotation moving axis 61 protrudes out radially outward
Bar 62, is equipped with keyhole in 61 one end of rotation axis, key is inserted into keyhole, and rotation is driven by rotating clockwise key
Axis 61 1 is logical to be rotated so that the end of drive rod 62 is abutted against with emergency stop bar 7, applies power to the left to emergency stop bar 7 with this so that
Emergency stop bar 7 is moved to the left with movable slider 5 and exits lockhole.
Emergency stop knob 6 in this electronic lock also has auto-reset function, and emergency stop knob 6 is connected with microcontroller, micro-control
Whether device processed can detect in real time is inserted with key in the keyhole of emergency stop knob 6, and the key signal detected according to this, judgement are
No driving emergency stop knob 6 rotates counterclockwise into capable reset.If detecting that key has been inserted into, microcontroller is not to emergency stop knob 6
Reset signal is sent, emergency stop knob 6 remains stationary as；If detecting that key has been pulled up, microcontroller sends multiple to emergency stop knob 6
Position signal, driving emergency stop knob 6 rotate counterclockwise into capable reset.
As shown in figure 3, a kind of charging gun with electronic lock, the electronics for being previously used for charging gun is installed in the charging gun
Lock.Wherein, T-shaped microswitch 1 is pressed by the axis hole of its 11 left end of button and being fitted in charging gun housing body 8 for shaft
The upper side wall stretching of the upper surface self-charging gun housing body 8 of key 11 is exposed outside；Be buckled the hook self-charging gun housing body 8 of 4 left ends
Left end stretches out；The remaining part of electronic lock is respectively positioned on inside charging gun housing body 8.
Mechanical lock unit in the electronic lock installed in this charging gun also further includes emergency stop knob 6 and emergency stop bar 7.Emergency stop
Bar 7 is vertically connected at the lower surface of sliding block 5.Emergency stop knob 6 is installed on the front of emergency stop bar 7, including rotation axis 61 and autorotation
The drive rod 62 that axis 61 protrudes out radially outward, the interior stretching of one end self-charging gun housing body 8 of rotation axis 61 is exposed outside, at the end
Portion is equipped with keyhole, and key is inserted into keyhole, rotates clockwise key and drives rotation axis 61 to rotate so that drive rod 62
End abutted against with emergency stop bar 7, apply power to the left to emergency stop bar 7 with this so that emergency stop bar 7 is moved to the left with movable slider 5
Exit lockhole.
Emergency stop knob 6 in this charging gun also has auto-reset function, and working method is identical with aforementioned electronic lock, this
Place is no longer repeated.
When this charging gun is connected with the power supply of new-energy automobile, the hook of 4 left ends of buckle can be with the interface pair of automobile power source
It should fasten；Then, automobile power system can send charging signals to microcontroller, when microcontroller receives the charging signals
When, it can power to electromagnetism parallel execution device and instruct its band movable slider to be moved to the left, the left end of sliding block is stretched into T-shaped microswitch
Lockhole, at this time T-shaped microswitch blocked and can not act by sliding block, be locking state so that buckle 4 left ends hook can not take off
From the interface of automobile power source, both are in locking state, i.e. charging gun can not be pulled out, and automobile power source keeps charged state.
When needing to pull out charging gun from the interface of automobile power source, it is necessary to which car owner is in the corresponding position brush of RFID module
Magnetic card once, RFID module can be to microcontroller transmission magnetic card signal, when microcontroller receives the magnetic card signal, meeting at this time
Power to electromagnetism parallel execution device and instruct its band movable slider to move right, the left end of sliding block is exited the lock of T-shaped microswitch
Hole, at this time T-shaped microswitch be in can unlocking condition, press T-shaped microswitch, the connecting rod of T-shaped microswitch moves downward, and
The right end of horizontal struts is pushed by baffle ring, compression reseting spring simultaneously makes horizontal struts drive buckle by the shaft of its left end
The hook of left end tilts slightly upwards, so that charging gun can be pulled up from the interface of automobile power source.
After removing charging gun, T-shaped microswitch is unclamped, horizontal struts move up reset under the action of resetting spring at this time,
At the same time reset is realized under the action of T-shaped microswitch and the also horizontal struts that are buckled.
Using this charging gun, when effectively can prevent that new-energy automobile charges, charging gun pulls out by mistake, that is, protects operator's
Personal safety, and automobile storage battery can be protected, greatly improve the security performance of new-energy automobile charging.
