Tool lock 1, mechanical lock 1 is in lockup state, can not manual unlocking, see Fig. 1 and Fig. 2.
The charge protection device of the electric automobile in this invention by controller of vehicle control, locking system be in freely or
During person's lockup state, its special version determines elliptic cam 4 and cannot rotate freely, it is ensured that the state of mechanical lock 1
Maintaining, shown mechanical lock 1 is under every kind of state and does not all need energy maintenance；When the state of mechanical lock 1 needs to change,
Being sent pulse signal by controller of vehicle, triggering elliptic cam 4 and rotate, the transformation of completion status, specific works mode is as follows：
1）When mechanical lock 1 is in lockup state, plane tappet 5 is in the position of cam major semiaxis 9, when controller of vehicle sends
When pulse signal is to step-by-step motor, step-by-step motor drives elliptic cam 4 half-twist so that plane tappet 5 is from cam
The position of major semiaxis 9 moves to the position of cam semi-minor axis 10, and plane tappet 5 rebounds, and mechanical lock 1 affranchises state, can hand
Move and open.
2）When mechanical lock 1 is in free state, plane tappet 5 is in the position of cam semi-minor axis 10, when wagon control dress
Putting when sending pulse signal to step-by-step motor, step-by-step motor drives elliptic cam 4 half-twist so that plane tappet 5
Move to the position of cam major semiaxis 9 from the position of cam semi-minor axis 10, plane tappet 5 rises and blocks mechanical lock 1, mechanical lock 1
It is in lockup state, can not manual unlocking.
As shown in Figure 5 and Figure 6, which is vehicle socket schematic diagram.With reference to GB《Electric car conduction charging connects
Device third portion：Direct-current charging interface》With《Electric car conduction chargeable connection device part 2：AC charging connects
Mouthful》, this schematic diagram briefly understands the structure of vehicle socket and the position of machinery fore shaft, and mechanical lock 1 is by machinery fore shaft
Stuck, the movement of constraint charging gun 8, mechanical lock 1 requires have certain rigidity and intensity, it is ensured that be difficult in the course of the work send out
Raw deformation, and there is antiwear characteristic.This schematic diagram is not drawn into charging plug contact specifically arrange, because connecing for AC charging
Mouth and direct-current charging interface, the positions and dimensions of internal charging plug contact is all different, needs to enter according to the species of charging pile
Row selects and arranges.
Fig. 7 is the charge protection control flow chart of electric automobile.Locking system in this invention is arranged on vehicle socket one
Side, during charging pile is to electric motor car charging, concrete workflow is as follows：
A) user logs in charging pile and uses system, manually extracts charging gun and is inserted in vehicle socket, fills electric motor car
Electricity；
B), after user confirms charging, whether the detection charging of charging pile control system is ready, when confirming ready,
Charging pile starts to charge up, and controller of vehicle sends pulse signal so that mechanical lock 1 is become locking shape from free state
State, thus ensure that in charging process, charging gun cannot be extracted.
C) when reaching the end-of-charge condition that user sets, controller of vehicle starts cycle transmission " in charging pile
Only charging message ", and control charging pile and stop charging, controller of vehicle sends pulse signal simultaneously, and control mechanical lock 1 is by locking
Only state becomes free state, manually extracts charging gun and completes charging.
D) when charging process is not up to the end-of-charge condition setting before user charges, but user needs to stop
During charging, system prompt user logs in charging pile and uses system, after confirming to log in and implement stopping charging instruction, and charging
Stake control system control electric automobile stops charging, and controller of vehicle sends pulse signal, and control mechanical lock 1 is by lockup state
Become free state, manually extract charging gun and complete charging；Midway is needed to stop under charge condition user, if user
Using system validation without logging into charging pile, mechanical lock 1 is in lockup state, and charging gun cannot be extracted.
E), after user stops charging, charging gun is extracted and is put back in stake by system voice prompting, and system enters standby mould
Formula, waits the use of next time.
By above workflow, charging pile charging gun when charging to electric motor car cannot be extracted, and is using
When person needs to stop charging, needing first to carry out logging in confirmation, charging gun just can be extracted afterwards.This invention achieves charging pile to electricity
Play the function of protection during motor-car charging, solve that charging gun is used by others in charging process, user's stopping of being eager is filled
What electricity may cause blocks the problem that interior remaining sum is wasted or is used by others, and locking system does not all need energy at each state
Amount maintains, and decreases energy loss, improves the security of charging process, protects the rights and interests of user.
