The under casing 1 is the open rectangular box body structure in upper end, four be connected to by base plate and vertically on bottom edge Individual enclosing composition；The vertical welding of corner bending is formed Jing after blanking by the under casing 1 by one block of plate.So to the greatest extent can may be used The reduction weld seam of energy, to avoid, weld seam is long to deform, and affects the sealing property of casing.

The side plate 2 is four, and highly identical, and top and bottom are respectively provided with the flange 21 for stretching out, four institutes State side plate 2 to be respectively fixedly connected with the outside of the enclosing, the lower surface of the side plate 2 is concordant with the lower surface of the under casing 1； The positioning pipe 3 is four, is fastened transversely to the inner top side of four side plates 2 respectively, and the upper surface of four positioning pipes 3 is put down Together, upper surface of the upper surface of four positioning pipes 3 higher than the side plate 2, difference in height need to be set according to the thickness of sealing strip Fixed, the thickness of usual sealing strip is 4.7mm, and this is that difference in height can be set to 2mm.Side plate 2 can be made by panel beating bending.

The height of the enclosing is that, less than 1/2nd of 2 height of the side plate, 1/3rd with 2 height of side plate are Preferably.

Four side plates 2 are kept off with four skirts of the under casing 1 and being fixed by spot welding or intermittent welding.

The relative side plate 2 of two of which in four side plates 2 is located between two other relative side plate 2, and Joint between two adjacent side plates 2 is fixed by way of inside and outside full weld.Namely in four side plates 2, two of which phase To side plate two other relative side plate is clipped in the middle, it is concordant with two ends, after overlap joint again row welding.

22 structure of the first flange, first flange 22 are respectively provided with positioned at the both sides of two relative side plates 2 in outside Between 21 while the top flange of the adjacent side plate 2 is in 21 and flange in the bottom and with the top flange side 21 and bottom method Blue side 21 is welded and fixed.When design, the spacing according to upper and lower flange is needed, the height of the first flange 22 is determined, Just can be engaged with upper and lower flange after so may insure bending, to play a supporting role, then row is welded to again Position can proof strength requirement.

The inner side of the side plate 2 is fixedly connected with the reinforcement gusset 4 of multiple vertical arrangements.Strengthen the shape and number of gusset Depending on field conditions, it is welded with 2 inwall of side plate.

The outside of the flange 21 at the top of four side plates 2 is respectively provided with 23 structure of the second flange of downward bending.

Also include four bar shaped angle steel 5, the bar shaped angle steel 5 is fixedly installed in the bottom of four side plates 2 respectively On flange 21.Bar shaped angle steel 5 can use angle steel as needed from appropriate size, length as needed to be cut i.e. Can.The stacked electrokinetic cell lodge body also includes upper lid 12 and sealing strip 13, and the upper lid 12 is installed on the case of top Body top, the sealing strip 13 be ring-type, be installed between the flange 21 of adjacent two layers casing and top box flange Between side 21 and the upper lid 12, the thickness of the sealing strip 13 is more than the upper surface and 2 upper table of the side plate of the positioning pipe 3 Distance between face.

The stacked electrokinetic cell lodge body also includes upper lid 12 and sealing strip 13, and the upper lid 12 is installed on top Casing top, the sealing strip 13 be ring-type, be installed between the flange 21 of adjacent two layers casing and top casing Between flange 21 and the upper lid 12, the thickness of the sealing strip 13 is more than the upper surface and the side plate 2 of the positioning pipe 3 Distance between upper surface.

A kind of stacked electrokinetic cell lodge body provided by the utility model, its number of plies is more than two-layer or two-layer, Its core utility model point is that upper layer box body is improved, and by rational structure design, not only can be ensured enough Intensity so as to the problems such as piling up without producing welding seam breaking due to insufficient strength can be laminated.

In sum, a kind of novel power battery lodge body provided by the utility model has the advantages that：

1st, the welding on box flange side, is the hypotenuse of welding in prior art, is leg now, weld seam compared with Short, the welding deformation amount of flange is less, and sealing is relatively preferable, while reducing welding capacity, has saved processing and manufacturing cost.

2nd, box flange side back patch weldering square tube, square tube are higher by flange 2mm, it is ensured that sealing strip is left more than the compression of 2mm Amount, sealing strip are easily failed if compressed too greatly, and water resistance can be reduced, and can also reduce the service life of sealing strip, Protection well can be formed after leaving compression surplus to sealing strip, and may insure that sealing is good all the time.

3rd, four side walls of casing all inside and outside full weld, and have flange to block, do not interfere with outward appearance, it is to avoid existing skill Because problem of appearance polishing welding seams in art, weld seam is caused to have trachoma, the situation of final leak.Flange is welded with upper and lower flange simultaneously Connect, like this in the case where outward appearance is not affected, while playing a part of to strengthen flange to improve overall construction intensity.

4th, it is adapted to two-layer and above stacking casing connection, rational in infrastructure, classification of waterproof is greatly improved.

5th, it is laminated casing and only needs to a upper lid, it is time saving and energy saving, and may insure that sealing is good, while saving manufacture Cost.

6th, can directly be laminated and pile up, be connected by flange, it is not necessary to support, save space.

7th, extruded and during seismic testing, its qualification rate ratio is greatly improved with existing casing.
