Specific embodiment

The utility model is described in further detail for specific embodiment with reference to the accompanying drawing.

As shown in Figure 1, 2, 3, the lead-acid accumulator shell 1 of the utility model, by taking 1 × 6 structure as an example, including kerve 2, Kerve 2 includes 3 and kerve mouth 4 inside kerve, five parallel settings of shelves lattice 53 inside the kerve in, pole group be placed on grade lattice 5 it Between, there is the equidistant rib 6 of several protrusions in the side of lattice gear 5, and the height of rib 6 is at least consistent with negative plate plate face height A, The top of rib 6 is preferably provided with intermediate incline, and the height of intermediate incline is no less than 3mm, and intermediate incline can enter slot to pole group It works as a buffer, 6 width B of rib is preferably 2.6-3.5mm；Shelves 5 upper thickness I1 of lattice is 1-1.2mm, and lower part thickness I2 is 1.7-1.9mm, the thickness of lattice gear 5 are gradually thickeied along kerve mouth 4 to inside kerve 3 direction from top to lower part；Rib 6 Thickness gradually decreased along kerve mouth 4 to inside kerve 3 direction from top to lower part, the thickness of lattice gear 5 and rib 6 Consistency of thickness of the sum of the thickness at the different cross section from top to lower part i.e. along kerve mouth 4 on inside kerve 3 direction, I.e. at different cross section, the sum of thickness dative 5 thickness of gear of rib 6 are equal, and thickness G is preferably 2.2-2.4mm；On side wall 7 Portion's thickness E 1 is preferably 3.3-3.5mm, and lower part thickness E 2 is preferably 2.8-3mm, and side wall 7 is in view of demoulding and reduces cost from upper It arrives down thinned；8 thickness of bottom wall is uniform, and thickness F is preferably 2.2-2.4mm；

It is preferably 2.1- that the side wall 9 that pole group does not stress, which is designed as the thickness C of side wall 9 thinner than stress surface 7, not stress, 2.3mm；Single lattice inner cavity rib space D is preferably 27-27.8mm；For increase pole group equipment pressure, shell both ends first with 6th single lattice stress surface side wall, 7 surface, which is thickeied to rib face, to be flushed, and thickening thickness is preferably 2.9-3.5mm.Battery slot length L Preferably 179-183mm, width W are preferably 76-78mm, and height H is preferably 148-150mm.

Compared with the prior art, battery compartment gear 5 is equipped with several ribs 6, and the number of rib 6 is more preferably greater than eight, every It is not less than 2.6mm with pole plate interface width, the 30% of lattice block face product is no less than with pole plate contact surface, pole group's two-way pressure is kept Unanimously, 30% or more the gross contact area Zhan Jiqun forced area of rib 6 has obvious inhibiting effect to pole group's expansion, keeps pole Group's pressure can guarantee the assembling pressure of pole group, also ensures acid content in technique requirement to control battery capacity, makes electricity The later period inducing capacity fading in pond is effectively suppressed, longer cell life；During the charging process, the oxygen that anode generates can pass through muscle The gap that 6 protrusion of item is formed is smooth to be diffused into negative terminal surface, and oxygen is avoided to concentrate on the reaction of negative plate top, this directly by opening The mode for the gas phase channel migration put is very much bigger than liquid phase diffusion rate, and the moving process of oxygen becomes easier to, oxygen cycle It is easier to establish, the degree of sulfation of pole group top and the bottom is uniform, is conducive to the consistency of pole group internal, while the muscle Material utilization amount is also reduced in the gap that 6 protrusion of item is formed, battery jar physical efficiency than conventional accumulators shell save 10% material at This, lattice block the height of the rib of protrusion not less than 0.2mm, it is ensured that oxygen cycle is smooth；The utility model rib 6 is preferably in shelves The two sides of lattice 5 are respectively provided with, and the contact surface of each lattice gear both sides lattice block reinforcement item 6 is parallel to each other, and the control of aspectant spacing is in 27- Between 27.8mm.The plane flushed with rib face is designed on the inside of the first of kerve both ends and the 6th single lattice side wall 7, thickness increases Greatly, intensity of the plastic housing on the group's Impact direction of pole is on the one hand greatly increased, another aspect effectively control first and the 6th single lattice Acid content, and improve the consistency of six single lattice cavity volumes.
