The assembling pressure of group is identical, improves battery.
As preferably, described depression is divided into upper and lower two, single depression from this side lower edges to the central area degree of depth
It is gradually increased.
All reinforcements in described depression are in sustained height.The height of reinforcement is less than or equal to cell body side, side
Just the space of accumulator is placed.
Owing to the stress of cell body stress surface is gradually to be incremented by central area by lower edges, therefore, of the present utility model
Concave design becomes and is formed slopely the inclined-plane that the degree of depth is gradually increased, the reinforcement being arranged in depression to central area from lower edges
Height be gradually increased to central area from lower edges, increase cell body side mechanical strength.
As preferably, the width of described depression is gradually reduced to central area from side lower edges.Depression is ladder in isosceles
Shape, upper and lower two depressions are symmetrical, and spacing 8-20mm, the section of this 8-20mm is positioned at the central area of cell body side.Depression
Peripheral side section also functions to the effect of reinforcement.
As preferably, the reinforcement in described depression is horizontally disposed with.In each depression, the quantity of the reinforcement of distribution is 3-6
Root, spacing is 5-15mm.
As preferably, described reinforcement is gradually increased from outer width inwards.Reinforcement near central area compares other
Reinforcement wider, higher, effectively promote the meteorism resistent performance of cell body central area.
As preferably, the depth capacity of described depression is 0.7-1.5mm.
In order to slow down the sour lamination of internal storage battery, sleeping the putting of accumulator assembled by this utility model makes pole group in flat
Put state.As preferably, both sides of the edge, described side are provided with convex tendon.Sleeping when putting use, the supporting surface that convex tendon is installed with battery connects
Touch, form gas channel between cell body side and supporting surface, be conducive to heat radiation；Carry by with flat when also providing installation simultaneously
