On the outer wall of the relative both sides of described casing, be symmetrically arranged with respectively connecting lug and spring bearer plate, wherein on a sidewall, be provided with pilot hole; Each spring bearer plate lower surface is fixed with respectively limit spring.

The equal correspondence in the top of described each hook and middle part is provided with locking groove and flange.

Advantage major embodiment of the present invention is in the following areas:

1, all constituent elementss all are integrated in casing, and volume is little, are convenient to the mounting arrangement on car body.

2, two hooks adopt the mode that is arranged symmetrically with, and are provided with flange and locking groove on each hook, have guaranteed that the on-vehicle battery group mounts reliable locking and convenient the strutting of linking up with in process.

The limit spring of 3, arranging on the outer wall of the relative both sides of casing plays the motion of restriction on-vehicle battery group vertical direction in the vehicle operating process, improves stability and the functional reliability of battery pack.

4, the pilot hole of arranging on the outer wall of the relative both sides of casing coordinates with the guide finger on the on-vehicle battery group, guaranteed the level attitude precision when battery pack mounts, and can limit the motion of on-vehicle battery group horizontal direction in the vehicle operating process, improve stability and the functional reliability of on-vehicle battery group.

The specific embodiment

As Figure 1-5, the hitch of the battery pack for pure electric automobile of the present invention, 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, in described two rotating

shafts

3,4, be hinged with a pair of hook 5,6, 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; Directly over electromagnet 2, be provided with armature 13, 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; Directly over hook 5,6, be provided with inverted T-shaped limiting stopper 15, 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, is set with preloading spring 17 on the guide rod 16 of inverted T-shaped limiting stopper 15; 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.On casing 1 relative both sides outer wall, be symmetrically arranged with respectively connecting

lug

19,20 and

spring bearer plate

21,22, 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.

Principle of work of the present invention is summarized as follows:

As Fig. 3, shown in Figure 5, when the present invention hung the on-vehicle battery group, hitch was 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, and hook 5,6 is realized reliable locking.Now limit spring 24,25 is in compressive state, the degree of freedom of restriction 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 Figure 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 are in the state of carrying of not being with, electromagnet 2 energisings are by armature 13 adhesives, armature 13 moves up by the resistance that drag-line 14 makes inverted T-shaped limiting stopper 15 overcome preloading spring 17, 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.
