Abstract
The utility model discloses a lead-acid battery tank. The lead-acid battery tank comprises a tank body with a tank opening and a baffle plate which divides the inner cavity of the tank body into a plurality of chambers, wherein a plurality of longitudinal ribs are arranged on two sides of the baffle plate and the inner wall surface, opposite to the baffle plate, of the tank body; and the thickness of each rib is gradually reduced from one end close to the tank opening to the other end. The battery tank disclosed by the utility model is provided with the ribs with gradually reduced thickness on the sides of the baffle plate, so that clusters arranged in the tank can be stressed evenly, polar plates are ensured to absorb acid evenly, and the service life of the battery is prolonged.
Description
Technical field
The utility model relates to the battery technology field, particularly a kind of Plumbic acid accumulator container.
Background technology
Along with popularizing of electric bicycle, electric bicycle has become one of nowadays main vehicles.The performance of electric bicycle internally-powered lead acid accumulator also receives the many concerns of People more and more.In the assembling process of power accumulator, suitable assembling pressure has very big influence to the performance of battery.At inside battery, dividing plate needs a suitable pressure tightly to contact with pole plate, makes the acid solution that is stored in dividing plate inside supply with pole plate fast, fully, and dividing plate is close to pole plate and can be prevented coming off of polar board surface active material in addition.But the assembling pressure of tension can destroy the fibre structure of dividing plate, and it is followed the string, and pick up descends.
Existing Plumbic acid accumulator container is moulded shell during fabrication because of the influence of draw taper because of storage battery, and cell jar is wide at the top and narrow at the bottom; The assembling pressure that causes utmost point crowd to pack into receiving behind the battery case chamber is inconsistent up and down, and promptly utmost point crowd the first half pressure is little, relatively pine; The latter half pressure is big, and is tighter.The problems referred to above cause the skewness of electrolyte in utmost point crowd top and the bottom, and the pole plate on top is inhaled the acid amount greatly, and it is less relatively that the pole plate of bottom is inhaled the acid amount, in use makes the active material of this part be not easy to transform.Along with the increase of cycle-index, the pole plate in the cell jar is easy to occur the phenomenon of layering, has influenced the discharge capacity and the useful life of storage battery.
The utility model content
The utility model provides a kind of Plumbic acid accumulator container, solved electrolyte in the traditional storage battery groove in the utmost point crowd top and the bottom skewness, very easily cause the problem of pole plate layering.
A kind of Plumbic acid accumulator container; The dividing plate that comprises the cell body of trough of belt mouth and the cell body inner chamber is divided into some chambers; The two sides of said dividing plate and the cell body internal face relative with dividing plate are provided with the rib of some vertical settings, and the thickness of said rib is reduced to the other end by the end near notch gradually.
Each side of dividing plate or the cell body internal face that each is parallel with dividing plate are provided with 5 equally spaced ribs, and rib quantity can not play respective action very little, then cause cost higher too much.
The width of said rib is preferably 1～5mm.
Said rib is a scarf near the end face of notch one end, and certain guide effect is provided.
The utility model battery case is provided with the rib of thickness-tapered in bulkhead sides, can make the cluster that is assemblied in the groove stressed evenly, guarantees that pole plate is whole to inhale acid evenly, thereby improves battery life.
Description of drawings
Fig. 1 is the structural representation of the utility model Plumbic acid accumulator container;
Fig. 2 is a cell jar A-A profile shown in Figure 1;
Fig. 3 is the vertical view of cell jar shown in Figure 1.
Embodiment
As shown in the figure, a kind of Plumbic acid accumulator container comprises the cell body 1 of trough of belt mouth 2 and cell body 1 inner chamber is divided into the dividing plate 3 of 6 chambers that the cell body internal face of the two sides of each dividing plate and parallel baffle is equipped with 5 ribs 4 that vertically are provided with.The thickness of rib 4 is from reduce to the other end near notch 2 one ends gradually.Because cell body 1 inner chamber generally is that to attend Panasonic tight, rib 4 is set can lets the effective width of chamber unanimous between the higher and lower levels, the pressure unanimity that finally lets the cluster of packing into bear.
This shows that the gradient of rib 3 need be according to the shape setting of cell body 1 inner chamber, pack in the chamber that rib 4 is set to scarf 401 near an end end of notch, forms guiding for the ease of cluster.The width of rib is set to 1～5mm in addition, and the rib quantity on the same side can be 3～10, and the spacing between the rib can be identical, also can be inequality.As shown in Figure 3, each side is provided with rib quantity and is 5 in the present embodiment battery case, and spacing equates, and is the mirror image setting.
Claims (4)
1. Plumbic acid accumulator container; The dividing plate that comprises the cell body of trough of belt mouth and the cell body inner chamber is divided into some chambers; It is characterized in that; The two sides of said dividing plate and the cell body internal face relative with dividing plate are provided with the rib of some vertical settings, and the thickness of said rib is reduced to the other end by the end near notch gradually.
2. Plumbic acid accumulator container according to claim 1 is characterized in that, each side of dividing plate or the cell body internal face that each is parallel with dividing plate are provided with 5 equally spaced ribs.
3. Plumbic acid accumulator container according to claim 1 and 2 is characterized in that, the width of said rib is 1～5mm.
4. Plumbic acid accumulator container according to claim 1 is characterized in that, said rib is a scarf near the end face of notch one end.
