Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Vertical lock locking device of the present utility model generally is fixed on the body of charging socket.Contrast Fig. 1, this lock uint mainly is comprised of housing 1, gear wheel 3a, pinion 3b, motor 2, driving-chain 3, lock collar 7, lock pin 9, lock pin spring 10, sensitive switch 13, microswitch cam 23 and lock pin cam 29.Special circumstances might occur when considering charging, for example have a power failure or mechanical disorder, can't realize electronic release, design an armstrong's patent release mechanism on the basis of above-mentioned lock uint.The vertical lock locking device that the below's concrete analysis the present embodiment provides.
Referring to Fig. 1, Fig. 3, large helical gear 6 coaxial lines in the vertical lock locking device be entrenched in gear wheel 6 lower ends, rotor is formed at and the top that is connected to lock collar 7 by screw 8 coaxial lines.This rotor upper end is by bearing 4, the lower end is rotatably connected on the housing 1 by the pivot pin 12a that is connected on the main body holder 12 on the housing 1, in described rotor one side motor 2 is set, this motor 2 is a direct current motor, pinion 3b is connected in the rotating shaft of motor 2, and pinion 3b even meshes with gear wheel 3a.Microswitch cam 23 is located at the downside of lock collar 7, and its cam surface 23a is arranged on the circumferential direction take the lock collar axis as center of rotation, and namely the radius of gyration of cam is vicissitudinous.Be provided with two sensitive switches 13 corresponding to these microswitch cam 23 1 sides, this sensitive switch 13 is provided with flexible contact spring 13a, be provided with contact 13b at the sensitive switch body, when the corresponding cam surface of the maximum rotating radius of microswitch cam 23 touches reed 13a, just its pressure is contacted on the 13b of contact, make sensitive switch 13 closures; When the corresponding cam surface of the maximum rotating radius of microswitch cam 23 is thrown off with the contacting of reed 13a, on the reed 13a disengagement contact 13b, sensitive switch 13 is opened.Two sensitive switch 13(are referring to Fig. 3, Fig. 4) just be used on control motor rotating.Lock pin cam 29 is the cam path of annular, and this cam path is arranged on the axial lower surface of lock collar 7, the center of rotation of this cam path and lock collar 7 coaxial lines, and the groove bottom of this cam path is described helicoid 29a, so the groove depth of this cam path is gradual change.Be provided with lockpin hole, the outside that is connected in this lockpin hole that an axle sleeve 11 is concentric with lockpin hole in the corresponding position corresponding to the housing 1 of this cam path.Be provided with shaft shoulder 9a on the lock pin 9, lock pin one end is provided with bulb, and this bulb is conflicted on helicoid 29a, and the other end is socketed in the axle sleeve 11, and lock pin 9 is conflicted on helicoid 29a in its axis mode parallel with rotor 7 axis.Lock pin spring 10 is socketed on the lock pin 9, and this spring one end is conflicted on the described shaft shoulder, and an end is conflicted on axle sleeve 11 corresponding end faces or on the corresponding medial surface in the housing.So axle sleeve 11 plays a part to the guiding of lock pin 9 with to lock pin spring 10 location.
Described rotor opposite side in housing 1 arranges bevel pinion 14 corresponding to the position of large helical gear, and this bevel pinion is bearing in the corresponding aperture of housing 1, and the axis in this hole is vertical with the housing corresponding side surface.The mechanical release mechanism that bevel pinion 14, large helical gear 6, driving core body 15 and unlocking tool 17 consist of in the present embodiment.Be connected by screw between pinion 3b and the driving core body 15, be provided with spring 18 between the two in order to prevent screw loosening.Drive being connected on the bevel pinion 14 of core body 15 coaxial lines.Drive core body 15 and be provided with hole slot 15a, the corresponding end of this unlocking tool 17 is provided with the boss 17a suitable with this hole slot, certainly also hole slot and boss can be arranged conversely, is separately positioned on unlocking tool 17 and the driving core body 15.The mating surface of hole slot 15a and boss 17a is discontinuous smooth arc surface, like this when the boss 17a of the corresponding end of unlocking tool 17 inserts the hole slot 15a that drives on the core body, unlocking tool 17 can drive and drive the synchronously rotation of core body 15 dos, rotate by large helical gear 6 and the engagement drive lock collar 7 of bevel pinion 14, lock pin cam 29 and lock collar 7 coaxial rotation reach the purpose of release.
Above-mentioned vertical lock locking device is connected with the charging socket body by main body holder 12, gives electricity by charging pile system.When charging, motor 2 drives described main body rotating mechanism by gear transmission chain 3 and is rotated in the forward an approximately circle, lock collar 7 is rotated thereupon, the helicoid 29a that is distributed in annular cam path bottom land constantly rises, promoting latch-locking 9 extend out in the charging plug, make charging socket and plug-locking, the motion process of its lock pin 9 can be referring to Fig. 1, Fig. 2.Meanwhile, along with the rotation of lock collar 7, microswitch cam 23 is also rotated thereupon, when lock collar 7 is rotated a circle, the maximum rotating radius place of microswitch cam 23 just in time touches the reed 13a pressure of a side sensitive switch 13 on the 13b of contact, makes sensitive switch 13 closures, sees also Fig. 3.This kind state description lock collar 7 is rotated in the forward and puts in place, i.e. locking puts in place, and the signal of telecommunication of sensitive switch 13 closures feeds back to system.If it is not in place that lock pin 9 stretches out, because microswitch cam 23 is rotated with lock pin cam 29 coaxial lines, then lock pin cam 29 also will rotate not in place, it can not be pressed to reed 13a on the 13b of contact, locking device can not provide the locking reverse electric feed signal, power supply can not be connected, and has guaranteed the safety of electricity consumption.When charging was finished, motor 2 drove by 7 reverse rotations of gear transmission chain 3 lock collars and approximately one encloses, and its helicoid 29a no longer promotes latch-locking 9, and locking plug spring 10 pushes up back upper locking plug 9, makes charging socket and plug release, and release is finished.Meanwhile, along with the backward rotation of lock collar 7, just in time be at its maximum rotating radius place on the corresponding position of contact 13b of opposite side sensitive switch, touch by the pressure of reed 13a and make this side sensitive switch 13 closures, see also Fig. 4.This moment, lock collar 7 reverse rotations put in place, i.e. release puts in place, and is the same with the situation of above-mentioned lock collar 7 forwards, and the signal of telecommunication of sensitive switch 13 closures also can feed back to system, makes the object of controlling make corresponding action.
