Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
As Fig. 1, 2, shown in 3 and 4, a kind of battery box servomechanism, comprise releasing claw 1, support 2, lever arm 4, strut bar 5, strut member 7, position-limited lever 8, strut member 7 has ratchet structure, the top of lever arm 4 is provided with handle 19, its bottom is hinged with ratchet 6 by bearing pin, 6, ratchet stands in described ratchet, ratchet 6 can carry out axial wobble around bearing pin, change acting point according to the different conditions that drags battery box, reach best laborsaving state, be provided with groove at lever arm 4 and ratchet 6 hinged ends, groove swings while changing acting point ratchet 6, carry out spacing to ratchet 6, at the parallel support 2 that is provided with of a side of lever arm 4, between support 2 and lever arm 4, be provided with position-limited lever 8, position-limited lever 8 has stretching structure, and position-limited lever 8 is preferably by consisting of two hinged rod members of bearing pin, and its two ends are hinged on support 2 and lever arm 4 by bearing pin, below described position-limited lever 8, be provided with strut bar 5, one end of strut bar 5 is fixedly connected on support 2, and the other end is hinged on lever arm 4 by bearing pin, between support 2 and lever arm 4, is provided with retracing spring 9, and retracing spring 9 is between position-limited lever 8 and strut bar 5, releasing claw 1 is arranged on support 2, between releasing claw 1 and support 2, is provided with slide block 3, and releasing claw 1 can longitudinal sliding motion on support 2 by described slide block 3, and releasing claw 1 is preferably two ends and is provided with vertically downward the body of rod of wedge.
As shown in Figure 5, a kind of more exchange device of battery box with this servomechanism, comprise framework, battery box servomechanism, battery box pallet 12 and the transfer roller 14 being formed by roller 13, pallet 12 bottoms are provided with cross slide way 16, pallet 12 is slidably connected at the top of framework by cross slide way 16, pallet 12 tops are provided with long rails 15, support 2 both sides, bottom at battery box servomechanism are provided with chute 20, battery box servomechanism is arranged on long rails 15 by chute 20, make battery box servomechanism along the longitudinal track 15 on pallet 12, slide, transfer roller is arranged on the top of described pallet 12, the both sides of battery box servomechanism, wherein roller 13 surfaces in the transfer roller of a side are provided with annular groove, the projection of annular groove and battery box 10 bottoms is oppositely arranged, in the time that releasing claw 1 drags battery box 10, projection is embedded in annular groove, guiding battery box 10 moves, prevent that it from rocking, be provided with leading screw 17 in the bottom of pallet 12, one end of leading screw 17 is fixedly connected with handwheel 18, and handwheel 18 is controlled pallet 12 by leading screw 17 and laterally slided on framework, load when battery box 10 can micro-regulating cell case 10 and the relative position of automobile batteries frame 11.
Battery box servomechanism of the present invention is the sight from the 11 interior hauling-outs of automobile batteries frame by battery box 10: ratchet 6 forms acting point with ratchet 7 in Fig. 2 state, because ratchet 6 and ratchet 7 positions maintain static, in the time that handle 19 is applied to enough horizontal pulls, to drive battery box 10 to start mobile, position-limited lever 8 is in stretching state, drive support 2 to slide on longitudinal rail 15, ratchet 6 disappears with the acting point at ratchet 7 places, battery box 10 slides in pallet 12 along roller 13, now, lever arm 4 resets in the effect of retracing spring 9.
Battery box servomechanism of the present invention longitudinally guide rail approaches the process of battery box 10: ratchet 6 is in the left side of lever arm 4 and follows lever arm 4 and slide, after releasing claw 1 completes battery box 10 crawls, manually ratchet 6 is pushed to the right side of lever arm 4, make a suitable flank of tooth on ratchet 6 and ratchet 7 form new acting point, convenient to battery box servomechanism generation power-assisted effect in battery box 10 pulling processes.
As shown in Figure 5, leading screw 17 has horizontal fine setting effect to pallet 12, after pallet 12 docks with automobile batteries frame 11, may there is alternate position spike on micro-left and right directions with two handles of battery box 10 in releasing claw 1, now by shake handwheel 18 ensure releasing claw 1 be just in battery box 10 directly over, facilitate crawl and the release of releasing claw 1 to battery box 10.
