Abstract

The utility model provides a new model valve controlled sealing lead-acid battery casing, which is to adjust the outline structure of the components of the casing, under the precondition of not changing the casing and shape of the same model and specification, by changing the internal and external structure of the existing battery casing. The main technical measure is to modify an original big vent hole and cover into a plurality of single vent holes relating to a cavity alternate with the baffle, and the hole cover is the fully sealed turn-over cover; to modify the internal wall glue groove of the upper cover casing into the communicating mode; to modify a vertical butt-welded element on the top end of the an original terminal group into a flat plate collecting bar butt-welded element, and the collecting bar is fit with the internal wall glue groove of the upper cover casing, so that the height of the upper cover casing is reduced, for increasing the height of the lower casing in equal value, therefore, the internal space of the battery can be enlarged, and the battery capacity can promote 8-12%, as well as the volumetric specific energy of the battery can be promoted, and at the same time, the internal structure of the casing is more firm, and the integrity of the casing is stronger.

Description

A kind of novel valve-regulated sealed lead-acid batteries housing

Technical field:

The utility model relates to battery technology, is specifically related to a kind of novel valve-regulated sealed lead-acid batteries housing.

Background technology:

Valve-regulated sealed lead-acid batteries because of distinct advantages such as have low pollution, long service life, maintenance is easy, cost is low, and is used widely in all trades and professions.This battery can have varied according to different needs, model specification.In order to adapt to the space of storage battery field of employment, its enclosure volume form with a kind of model specification is constant substantially, the battery inner capacities also is certain, and valve-regulated sealed lead-acid batteries is keeping this traditional enclosure volume form and immanent structure always for these years.

Summary of the invention:

The utility model proposes a kind of novel valve-regulated sealed lead-acid batteries housing, it is by changing the immanent structure of battery container, reach under the constant prerequisite of same model specification enclosure volume form, the inner space of adjusting housing component parts contour structures and improving battery to greatest extent, increase the volume of battery specific energy, realize that simultaneously the housing immanent structure is more firm, the shell globality is stronger.

Technical solution of the present utility model:

What the utility model was same as the prior art is: include shell of top cover and lower house.Its shell of top cover includes ventilation hole and lid, inwall includes the glue groove; Include utmost point group, dividing plate in its lower house, the pole group is installed in groups by in the alternate cell body of mid-board plate.And institute's difference is:

(1) a whole rectangle ventilation slot that former shell of top cover is set and sheet lid, it is relative to be improved to each hole cavity alternate with dividing plate, and port lid is hermetically sealed renovating;

(2) changing the shell of top cover inwall former is communication type glue groove to weldment glue groove;

(3) change conventional art utmost point group and weldment is striden bridge be connected to and pass a bridge connect, constitute bus-bar and coincide with the communication type glue groove that weldment is fused into one with the shell of top cover inwall, whole bus-bar and pole wrap in the seal;

(4) height that changes the mid-board plate is lower than lower house surrounding height, and the pole head of institute's exposure seals at its neck place;

(5) based on the improvement of above structure, the utility model reduces the height of shell of top cover, increased the effective depth in the lower house, and whole housing overall dimension is identical with conventional art.

The beneficial effects of the utility model:

(1) because the utility model pole group is that flat butt welding, formation bus-bar formula are to weldment, bus-bar is identical with the glue groove of shell of top cover inwall again, then reduced space to the occupied shell of top cover of weldment, thereby can reduce the height of shell of top cover, the height of increase lower house, thereby improved the inner space of battery, compare with the storage battery of former identical appearance size, battery capacity improves 8-12%.Increased the battery volumetric specific energy.

(2) the utility model is with the glue groove that is communicated with, and pole, bus-bar are linked to be single piece to weldment, and the phase mutual edge distance is little, in conjunction with firm, low, the good electrical property of resistance.

When (three) the utility model was done sealing, fluid sealant flowed in same connection glue groove, can guarantee the uniformity of glue amount, and shell of top cover and lower house bonding are also more firm.

(4) the utility model good integrity, good looking appearance.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the utility model shell of top cover interior wall construction schematic diagram;

Accompanying drawing 3 is for establishing the structural representation of dividing plate in the utility model lower house;

Accompanying drawing 4 is the structural representation of the utility model lower house upper surface.

Embodiment:

The utility model as shown in Figure 1 mainly is made of shell of top cover 1,

lower house

2, and 10 is the sealing overturn cover of ventilation hole shown in the shell of top cover 1, shown in 12 be the positive and negative electrode post, on the lid shell face, with holes rectangular in both sides be installing hole handle 13.As shown in Figure 2, glue groove 14 is connected state, also is provided with two abreast; Ventilation hole 11 is positioned at the shell of top cover major axis to position placed in the middle, can have independent a plurality of, its quantity depend on dividing plate institute separate space body what and decide.And for example shown in Figure 3, the cavity between the lower house dividing plate 21 have six can be corresponding in six ventilation holes.As shown in Figure 4, the top of the pole group 22 among the figure in the lower house is welded in the below of flat bus-bar 23 by positive-negative polarity, and bus-bar can match with the glue groove 14 of shell of top cover inwall again.In addition: the height value that height value and lower house increased that the utility model shell of top cover 1 is reduced is 0.5-1cm; The height of the mid-board plate of lower house 2 is lower than lower house surrounding height 3-5mm.

Upper casing of the present utility model and lower house are all taked accurate injection molded.
