Description
Technical field
The present invention relates to a kind of lead-acid accumulator, especially a kind of lead-acid accumulator shell.
Background technique
Currently, 1 × 6 structure kerve structure of valve-regulated lead-acid battery is that internal lattice gear surface is not provided with rib, this is used
The inside battery oxygen cycle of kind kerve obviously concentrates on pole group top, leads to the obvious sulfation in negative plate top, moulds in addition
Shell demoulding needs constant slope, and more so as to cause pole group top acid content, the electrochemical reaction of upper active substance compares lower part
More or electric discharge is deep, keeps entire cluster group top and the bottom current distribution is uneven even.On the other hand existing battery case is not enough to pole
In the case that group's side negative plate forms enough pressure, furthermore each single lattice assembling pressure of battery is the same, first and the 6th single lattice
The deformation quantity of blow-up is bigger than intermediate four single lattices, therefore first is also higher than remaining single lattice with the 6th single lattice acid content, in plastic housing
Chamber is designed to the method for isometric(al), and there are obvious shortcomings.In terms of the return of goods situation of market, battery blow-up is concentrated mainly on pole group's stress
On direction, therefore the plastic housing intensity of pole group's Impact direction is obviously inadequate.
Summary of the invention
In order to solve the above-mentioned technical problems, the present invention provides a kind of lead-acid accumulator shells, including kerve, kerve to include
With kerve mouth inside kerve, the shelves lattice inside the kerve are set, pole group is placed between the shelves lattice, which is characterized in that
The thickness in shelves lattice section increases along kerve mouth to the direction inside kerve, on the shelves lattice along the kerve mouth to
Direction inside the kerve is additionally provided with a series of ribs, and the thickness of the rib is along the kerve mouth into the kerve
The direction in portion is reduced, along the kerve mouth at different cross section on the direction inside the kerve, shelves lattice section
Thickness it is equal with the sum of the thickness of the rib.
Further, the height of the rib is more than or equal to pole plate height.
Further, the top of the rib is equipped with intermediate incline.
Further, the rib thickness is not less than 0.2mm.
Further, the rib at least 8, the area ratio of the area that the rib is contacted with pole plate and shelves lattice is greater than
Equal to 30%.
Further, the two sides of the shelves lattice are arranged in the rib.
Further, the opposite rib of the shelves lattice, surface is parallel to each other, and aspectant spacing is between 27-27.8mm.
Further, the kerve includes the side wall and stress side wall that pole group does not stress, and the thickness for the side wall not stressed is small
In the thickness of the stress side wall.
Further, the thickness for the side wall not stressed is between 2.1-2.2mm.
Further, the thickness of the side wall of stress is flushed with rib face, with a thickness of 2.9-3.5mm.
Lead-acid accumulator shell of the present invention can be improved the performance of battery and reduce cost.
Detailed description of the invention
Fig. 1 is lead-acid accumulator schematic diagram of housing structure of the present invention；
Fig. 2 is the cross-sectional view in Fig. 1 at B-B；
Fig. 3 is the cross-sectional view in Fig. 1 at A-A.
Specific embodiment
The invention will be further described for specific embodiment with reference to the accompanying drawing.
As shown in Figure 1, 2, 3, lead-acid accumulator shell 1 of the invention, by taking 1 × 6 structure as an example, including kerve 2, kerve 2
Including inside kerve 3 and kerve mouth 4, five parallel settings of shelves lattice 53 inside the kerve in, pole group is placed between grade lattice 5, lattice
There is the equidistant rib 6 of several protrusions in the side of gear 5, and the height of rib 6 is at least consistent with negative plate plate face height A, rib 6
Top 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 and play buffering work
With 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 is gradually thickeied along kerve mouth 4 to inside kerve 3 direction from top to lower part；The thickness of rib 6 is from upper
Portion is to gradually decrease along kerve mouth 4 to inside kerve 3 direction to lower part, and lattice keep off the sum of 5 thickness and the thickness of rib 6 and exist
The consistency of thickness from different cross section from top to lower part i.e. along kerve mouth 4 on inside kerve 3 direction, i.e., cut in difference
At face, the sum of thickness dative 5 thickness of gear of rib 6 are equal, and thickness G is preferably 2.2-2.4mm；7 upper thickness E1 of side wall is most
It is well 3.3-3.5mm, lower part thickness E 2 is preferably 2.8-3mm, and side wall 7 is subtracted from top to bottom in view of demoulding and reducing cost
It is thin；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, the gross contact area of rib 6 accounts for pole 30% or more forced area of group, 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；Rib 6 of the present invention is preferably in shelves lattice 5
Two sides be respectively provided with, 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.
