The specific embodiment
As Figure 1-5, the hitch of the battery pack for pure electric automobile described in the utility model, comprise casing 1; Described casing 1 inner bottom part is fixed with electromagnet 2, on the tank wall of described electromagnet 2 one sides in position, horizontal interval (HI) is fixed with two rotating shafts 3,4, be hinged with a pair of hook 5,6 in described two rotating shafts 3,4, described two hooks 5,6 are connected with tank wall by the torque spring 7,8 be sleeved in two rotating shafts 3,4 respectively, and the equal correspondence in top and middle part of each hook 5,6 is provided with locking groove 26 and flange 27; Be positioned on the tank wall directly over electromagnet 2 and described hook 5,6 intrinsic spacing guide plate 9,10 respectively, be positioned on the tank wall of described two spacing guide plate 9,10 tops and be fixed with respectively guidepost 11,12; Be provided with armature 13 directly over electromagnet 2, described armature handle slides through the spacing guide plate 9 that is positioned at electromagnet 2 tops and is connected with an end of drag-line 14; Be provided with inverted T-shaped limiting stopper 15 directly over hook 5,6, the guide rod 16 of described inverted T-shaped limiting stopper 15 slides through the spacing guide plate 10 that is arranged on described hook 5,6 tops and is connected with drag-line 14 other ends of walking around described two guideposts 11,12, on the guide rod 16 of inverted T-shaped limiting stopper 15, is set with preloading spring 17; Be positioned on the tank wall of linking up with under 5,6 and offer the suspension mouth 18 for the loading, unloading battery pack.Be symmetrically arranged with respectively connecting lug 19,20 and spring bearer plate 21,22 on casing 1 relative both sides outer wall, wherein on a sidewall, be provided with the pilot hole 23 coordinated with guide finger on the on-vehicle battery group; Each spring bearer plate 21,22 lower surface is fixed with respectively limit spring 24,25.
The utility model principle of work is summarized as follows:
As shown in Fig. 3, Fig. 5, when the present invention hangs the on-vehicle battery group, hitch is in free state.Lifting mechanism holds up the on-vehicle battery group and moves up, in moving process, the flange 27 of on-vehicle battery group hitch point 28 meeting promotion hooks 5,6 makes to link up with 5,6 resistances that overcome torque spring 7,8 and 3,4 rotates around the shaft, hook 5,6 progresses into locking states, when hook 5,6 lockings put in place, inverted T-shaped limiting stopper 15 falls to entering in the locking groove 26 at hook 5,6 tops in the effect of preloading spring 17, links up with 5,6 and realizes reliable locking.Now limit spring 24,25, in compressive state, limits the degree of freedom of on-vehicle battery group vertical direction; Guide finger on the on-vehicle battery group penetrates in pilot hole 23, thus the degree of freedom of restriction on-vehicle battery group horizontal direction.
As Fig. 4, shown in Fig. 5, when the present invention dismantles the on-vehicle battery group, at first lifting mechanism holds up vehicle-mounted on-vehicle battery group, make to link up with 5, 6 in not being with the state of carrying, electromagnet 2 energisings are by armature 13 adhesives, the resistance that armature 13 makes inverted T-shaped limiting stopper 15 overcome preloading spring 17 by drag-line 14 moves up, when moving to, inverted T-shaped limiting stopper 15 breaks away from hook 5, during 6 top locking groove 26, hook 5, 6 at torque spring 7, under 8 effect along rotating shaft 3, 4 rotations, hook 5, 6 open, the lifting mechanism holder the on-vehicle battery group and is fallen, thereby complete the dismounting of on-vehicle battery group.
