detailed description of the invention:
Please refer to shown in Fig. 1 to Fig. 3, the utility model safety lock 1 is on electrical automobile charging plug 5, and wherein charging plug 5 comprises plug body 11, mechanical lock 12, turning cylinder 13, microswitch 14 and the second stage clip 15.Wherein mechanical lock 12 is fixed on plug body 11 by turning cylinder 13, microswitch 14 and the second stage clip 15 are installed on the below of mechanical lock 12, microswitch 14 and mechanical lock 12 constitute link gear, namely once press mechanical lock 12, microswitch 14 will be triggered, will the power-off of charging process be caused.If desired charge, only charging plug 5 and charging socket 3 need be plugged together and put in place, now on charging plug 5, mechanical lock tapered end 12a falls into the locked groove 3a of charging socket 3, mechanical lock 12 is in lockup state under the effect of the second stage clip 15, charging can normally be carried out, but mechanical lock 12 still can be pressed, thus microswitch 14 is caused to trigger and cause charging termination.
The safety lock 1 that the utility model is used for electrical automobile charging plug comprises lock core 6, straight pin 7, lock ring 8, first stage clip 9 and levels up circle 10, wherein lock ring 8 above with two " " " shape groove 16; " " " shape groove 16 has inlet slot 16a, the groove 16b that turns round, lock slots 16c, inlet slot 16a is symmetrical on lock ring 8, turn round groove 16b bottom inlet slot 16a along lock ring 8 circle distribution, and having certain angle with inlet slot 16a, lock slots 16c is above the bottom of groove 16b of turning round.What the lateral surface of lock ring 8 was provided with symmetry cuts flat portion 8a, makes lock ring 8 with anti-rotating function by the flat portion 8a that cuts of this symmetry.Lock core 6 one end end face is with the cavity 6a coordinated with private key 17, and the other end is lock pin 6b.Above lock core mandrel 6c, tight fit is provided with a straight pin 7, and straight pin 7 is positioned at lock core mandrel 6c Central Symmetry position, and straight pin 7 home position is in inlet slot 16a place, and the first stage clip 9 to be arranged on lock core 6 and to be entangled by lock ring 8.Lock and unlock all must apply power on lock core 6 with private key 17, makes it lock or unlocks, and the lock and unlock action of safety lock 1 is all moved forward and backward by lock pin 6b level to realize.Safety lock 1 is locked, and lock pin 6b is horizontal forward to be moved a certain distance, and is close on mechanical lock 12, prevent mechanical lock 12 again to be pressed, safety lock 1 unlocks, and lock pin 6b level moves a certain distance backward, return to original position, now mechanical lock 12 can freely be pressed.
If when having electronic lock 4 or electronic lock 4 do not have fault to lock to charging socket in charging process 3, then also need the additional microswitch 2 of increase by, wherein additional microswitch 2 is normal open switch, and it controls its action by lock pin 6b horizontal shifting.Above-mentioned safety lock 1 and additional microswitch 2 are all mounted in charging plug 5, work together with coordinating with part such as mechanical lock 12 grade existing in charging plug 5, leave the installing space of safety lock 1 and annex microswitch 2 simultaneously at plug body 11, and leave the movable space of lock pin 6b level.
If when charging socket in charging process 3 is with the electronic lock 4 that can normally work, additional microswitch 2 just can not be installed.Now, if after installation insurance lock 1, put in place when charging plug 5 and charging socket 3 plug together, re-use private key 17 pairs of lock cores 6 and first apply a thrust, straight pin 7 on lock core 6 is made to shift the inlet slot 16a bottom land of lock ring 8 onto, again first a revolving force is applied to private key 17, straight pin 7 on lock core 6 is made to rotate to the groove 16b bottom land that turns round, extract private key 17 again, straight pin 7 springs in lock slots 16c automatically, lock pin 6b is horizontal forward simultaneously moves a certain distance, and be close to and be positioned on charging plug 5 on mechanical lock 12, now cannot press mechanical lock 12, thus avoid because triggering microswitch 14 causes charging termination phenomenon.If need to stop charging, private key 17 pairs of lock cores 6 are used first to apply a thrust, straight pin 7 on lock core 6 is gone out of lock groove 16c simultaneously shift the groove 16b bottom land that turns round onto, again to private key 17 apply one with contrary revolving force of locking, straight pin 7 on lock core 6 is made to rotate to the inlet slot 16a bottom land of lock ring 8, extract private key 17, straight pin 7 automatically restores to inlet slot 16a place, lock pin 6b level moves certain distance backward simultaneously, mechanical lock 12 can freely be pressed, press mechanical lock 12, trigger microswitch 14, power-off, finally charging plug 5 is extracted from charging socket 3.
If installed additional microswitch 2, additional microswitch 2 has been normal open switch, and when safety lock 1 is locked, lock pin 6b level triggers additional microswitch 2 in moving process forward, and additional microswitch 2 will send signal to charging system, now start to charge.If need stop charging, safety lock 1 unlocks, and now lock pin 6b level moves backward, additional microswitch 2 disconnects, and will send signal to charging system, now power-off, mechanical lock 12 can be pressed like this, charging plug 5 is extracted from charging socket 3, avoid and chargedly extract phenomenon.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art, can also make some improvement under the prerequisite not departing from the utility model principle, these improvement also should be considered as protection domain of the present utility model.
