Fig. 8 shows the structural representation that the Battery case Locking Device of the utility model embodiment is connected with internal box.As shown in Figure 8, comprise that the Battery case Locking Device of lockable mechanism 1, interlocking gear 2 and anti-interlocking gear 3 is connected with the internal box 100 in order to hold battery.
In the present embodiment, fixed parts 34 is connected with internal box 100 by many groups of the first bolt connecting devices.
In the present embodiment, preferably, internal box 100 has the fixed cover coordinating with the first axially extending bore 211a clamping of chain dish 211.On fixed cover, be provided with the locking claw clip of chain dish 211 and connect the U-shaped groove coordinating.
After the chain pin 311 in fixed parts 34 and chain dish 211 are removed and are coordinated, draw outward after chain dish 211, can drive first connecting rod 12, second connecting rod 15 to bounce back, thereby drive dead bolt 11 to bounce back, dead bolt 11 is removed and is coordinated with the lock of outer case, completes release action.
When chain dish 211 is pushed back, when the back plate surface butt of chain dish 211 and internal box, first connecting rod 12, second connecting rod 15 are pushed out, and the dead bolt 11 of lockable mechanism 1 coordinates with the plug of the lock of outer case, and the locking that completes Battery case Locking Device moves.Meanwhile, chain pin 311 coordinates with the first radial direction through hole 211b clamping of chain dish 211 under the elastic force effect of the first elastic element 331, thereby realizes the object that prevents Battery case Locking Device automatic unlocking.
Fig. 9 shows the structural representation that the Battery case Locking Device of the utility model embodiment coordinates with tripper.As shown in Figure 9, tripper 200 comprises solution lock assembly 201, separates lock tube 203, push part 204, magnet 205 and mandrel 208.Wherein, solution lock tube 203, push part 204 are fixedly connected with mandrel 208 respectively.Magnet 205 is connected in one end of mandrel 208.
Release and the locking method of lower mask body to Battery case Locking Device is described:
Shown in collective diagram 3, Fig. 5 and Fig. 9, in the time that needs carry out release to Battery case Locking Device, first tripper 200 is inserted in the first axially extending bore 211a of the chain dish 211 of locking part 21, stop when separating when lock assembly 201 is crossed the lock pawl as release component 22, now, due to the elastic force effect of spring, lock pawl ejects and is arranged in and separates lock assembly 201 and separate the dead slot that lock tube 203 forms; Meanwhile, separating under the driving of lock assembly 201, driving lever 332 is synchronized with the movement with release pin 333, be that driving lever 332 drives release pin 333 to move up in the inside of radial hole 211b, thereby the chain pin 311 of jack-up is until chain pin 311 departs from chain dish 211, after chain dish 211 loses the constraint of chain pin 311, along in Fig. 9 when drawing chain dish 211 outside right side, can drive dead bolt 11 to reach the object of release.
If tripper need to be exited from chain dish 211, must allow tripper continue a mobile segment distance towards left side along the direction of Fig. 9.Because lock pawl is provided with groove, to cross after lock pawl when separating lock tube 203, lock pawl rests in the circular trough of separating lock tube 203.The magnet that is meanwhile embedded in mandrel 208 one end is inhaled mutually with the backboard of internal box.In the time that tripper moves towards right side, the magnet 205 and the mandrel 208 that are adsorbed in the backboard of internal box first do not move with the movement of tripper, are fixedly connected with mandrel 208 owing to separating lock tube 203 by straight pin 206, therefore, separate lock tube 203 also motionless.Separate like this lock assembly 201 along with moving to right of tripper drawn close to separating lock tube 203 gradually, finally make to separate lock assembly 201 and separate 203 two mutual butts of part of lock tube.In the time that tripper continues to move to right, separate lock assembly 201 and force to separate after lock tube 203 and move, be stuck in like this lock pawl in the circular trough of separating lock tube 203 sliding along separating on the groove of lock tube 203, owing to separating lock assembly 201 and separating butt of lock tube 203, do not produce dead slot, lock pawl can not snap in dead slot inside.Separate like this lock assembly 201 and just can cross lock pawl, tripper is exited smoothly.
Can find out from above description, embodiment of the present utility model has realized following technique effect: owing to having as the chain pin of unlocking prevention parts with as the chain dish of chain main body, chain pin has primary importance and the second place, in primary importance, chain pin and chain dish clamping, in the second place, chain pin and chain disk detachment, thereby chain pin is switched between primary importance and the second place, can realize clamping and the disengaging of unlocking prevention mechanism and interlocking gear, thereby realize the object that prevents Battery case Locking Device automatic unlocking; By elastic compensating parts are set, can compensate the endplay between dead bolt and first connecting rod, thereby according to actual installation situation to dead bolt move axially surplus adjustment, each dead bolt can be adapted to and the position deviation of the lock of outer case.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
