Description

A kind of utmost point group structure that increases the lead acid accumulator of inhaling the acid amount
Technical field
The utility model relates to the lead acid accumulator technical field, relates in particular to a kind of utmost point group structure that increases the lead acid accumulator of inhaling the acid amount.
Background technology
The development of power lead acid accumulator has become the focus that consumer and manufacturer pay close attention in capacity and useful life so far.And concerning storage battery, the acid amount is on the low side to be a restriction battery capacity and a key reason that causes storage battery shortening in useful life.
Existing lead acid storage battery pool structure generally comprises battery case, battery cover and is located at the utmost point crowd in the battery case; Single utmost point crowd is made up of the bus-bar of positive and negative pole plate, dividing plate and connection pole plate, and the top sides of pole plate is exactly that the lug on positive plate or the negative plate is coupled together along lug, the function of bus-bar are arranged; Dividing plate is except keeping apart positive and negative pole plate; Its important function is to absorb acid solution, so that ion can be walked therein, the suction acid amount of dividing plate has determined the discharge capacity of battery.
Chinese patent 200920197872.6 discloses a kind of storage battery that prevents the anti-dress of utmost point crowd; Comprise battery case and groove lid; The battery case inner chamber is separated into several cells by dividing plate; The utmost point crowd who is made up of positive plate, negative plate and dividing plate is housed in each cell; Utmost point crowd top is provided with two bus-bars that respectively lug of the lug of all positive plates and all negative plates welded together, and wherein welds between bus-bar and the cell sidewall of all positive plate lugs and leaves a gap, and described groove cover cavity is provided with the location-plate that said gap is stretched in the bottom.
Chinese patent 200520012963.X discloses a kind of storage battery of low consumption good airproof performance; Comprise battery case, place a plurality of utmost point crowds that battery case inside separates by dividing plate and the middle cover that cooperates with battery case; In cover and be provided with cover plate, be provided with some pole plates, positive negative bus in the utmost point crowd, be provided with the connector of " several " font between the inner two consecutive roots crowds of battery case; The end span frame is on dividing plate on the connector, and the brace of two ends arcuation connects dividing plate both sides utmost point crowd's positive and negative bus-bar respectively; Be provided with the plastics pecten between pole plate top and the bus-bar; The cell wall of the groove that cooperates with battery case around the middle cover bottom surface is provided with semicircular positioning convex.
The disclosed accumulator pole group of above-mentioned patent has all adopted traditional structure; The battery acid amount is conventional the setting; Battery capacity is lower; When the battery of said structure kind is taken out spent acid after charging is accomplished in addition, might take out a little angle of dividing plate of playing buffer action between positive/negative plate, cause opening circuit between the positive/negative plate.
Summary of the invention
The utility model provides a kind of utmost point group structure of lead acid accumulator, and it lays dividing plate through making full use of inner idle space, has improved and has inhaled the acid amount, and then improved the discharge capacity of battery.
A kind of utmost point group structure of lead acid accumulator comprises the positive and negative pole plate of being with lug, and longitudinal baffle and bus-bar are equipped with the several layers lateral partitions between described bus-bar and the longitudinal baffle.
Among traditional utmost point crowd; Leave certain gap between bus-bar bottom surface and the longitudinal baffle, this space is vacant for fully, and the utility model utilizes this space to be used to lay lateral partitions; The material of lateral partitions and the material of longitudinal baffle are identical; Can inhale acid equally and store acid solution, so just can increase utmost point crowd's suction acid amount, simultaneously the also acid amount in the balancing battery better.
Preferably, the whole utmost point crowd of described lateral partitions bedding, described lug runs through lateral partitions, promptly in the whole space between bus-bar and the longitudinal baffle lateral partitions is arranged all, increases to inhale sour effect.
Described lateral partitions is 3~6 layers, and block board thickness is variant, can select tired the stacking of dividing plate of different-thickness or same thickness, to increase the acid amount.
Described bus-bar has two, connects anode plate and negative plates respectively, is equipped with baffle on the lateral partitions between two bus-bars, can avoid drawing spent acid process median septum and be destroyed.
Said longitudinal baffle and baffle bottom surface are close to described lateral partitions respectively, improve utilization of space to greatest extent, make the dividing plate number of plies reach maximum.
The lug side is close in described baffle both sides, improves the protection range of baffle to greatest extent.
Described bus-bar is pushed down described baffle, prevents to inhale in the sour process baffle and floats and assemble dislocation.
The utility model utilizes the space between bus-bar and the longitudinal baffle to lay lateral partitions, can increase the dividing plate quantity in the utmost point crowd, thereby improves utmost point crowd's suction acid amount, under the situation that other structure does not change, can improve the discharge capacity of storage battery.
Description of drawings
Fig. 1 is the utility model utmost point group structure sketch map;
Fig. 2 is a utmost point crowd's shown in Figure 1 left view.
Embodiment
As illustrated in fig. 1 and 2, a kind of utmost point group structure of lead acid accumulator comprises negative plate 1, positive plate 2, dividing plate 3 and bus-bar 4,5; Except that the negative plate of both sides, all the other pole plate both sides all are surrounded by dividing plate 3, are respectively equipped with lug 201,101 on positive plate 2 and the negative plate 1; Bus-bar 4,5 welds with lug 101,201 respectively; Thereby be together in parallel negative plate 1, positive plate 2 respectively, negative plate 1 is 8 in this structure, and positive plate is 7.
Dividing plate 3 is vertically to be provided with, and the top is along extending to the lug place.Bus-bar 4 is made up of cross structure 401 and pole 402, and bus-bar 5 is made up of cross structure 501 and pole 502, between the edge, top of cross structure and dividing plate 3, an intersegmental crack is arranged, and is equipped with the dividing plate 6 of 4 layers of horizontally set in this gap.In order to make full use of this space, dividing plate 6 beddings whole utmost point crowd, end face and bottom surface are close to the edge, top of cross structure and dividing plate 3 respectively simultaneously.Certainly according to the block board thickness difference, can adjust the number of plies of dividing plate 6, be generally 3~6 layers.
After battery assembling is accomplished, need spent acid be inhaled at last and go, corner that may the broken parts dividing plate, therefore at two bus-bars 4, laid baffle 7 between 5, in order to make full use of baffle, the side of lug 101,201 is being pasted in baffle 7 both sides; Pushed down by bus-bar 4,5 simultaneously, can prevent that baffle 7 is subjected to displacement.The thickness of baffle 7 has promptly been saved material less than the thickness of cross structure in addition, has increased the inner space again.
Because the utility model utmost point crowd Duo the dividing plate 6 of horizontally set than traditional structure, therefore can increase utmost point crowd's suction acid amount, and then the discharge capacity of raising storage battery.
