Description

A kind of storage battery

Technical field

The utility model relates to a kind of storage battery, is meant a kind of storage battery of low consumption good airproof performance especially.

Background technology

The matched battery of LEV (Light Electric Vehicle) adopts four 12V20Ah storage battery series connection to use mostly, the about 40-45Km of the continuation mileages for one time charging of this battery, useful life was at 6-8 month, and battery under normal circumstances useful life should be at 15N18 month, so short mileages of continuation, can't satisfy user's requirement, such battery mileages of continuation and useful life weak point mainly be that more high-power the continuing down of storage battery used, the applied load of battery is excessive, the ability to bear that has exceeded battery must cause battery to shift to an earlier date end-of-life.

Utility model patent ZL97210903.X discloses that a kind of to have voltage big, internal resistance is little, the interior connection storage battery of advantages such as power output is big, monomer accumulator jar by 7 2V is formed, each monomer accumulator jar comprises positive plate, negative plate, accumulator jar hamper accumulator jar housing, each accumulator jar also comprises interior joint pin box sealing plate, one end of interior joint pin connects with the positive plate of a monomer accumulator jar, the other end of interior joint pin connects with the negative plate of adjacent another monomer accumulator jar, sealing plate is contained on the inwall of accumulator jar housing, and the electric power storage bottle cap is encapsulated in the top of accumulator jar housing by pitch.This technical scheme complex structure, processing technology thereof is loaded down with trivial details.

The utility model content

The utility model provides a kind of storage battery of low consumption good airproof performance.

The purpose of this utility model is achieved through the following channels: a kind of storage battery, comprise battery case, place a plurality of utmost point groups 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, bus-bar in the utmost point group, be provided with the connector of " several " font between the inner two consecutive roots groups of described 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 group's positive and negative bus-bar respectively; Be provided with the plastics pecten between described pole plate top and the bus-bar.

The cell wall of the groove that cooperates with battery case around the described middle cover bottom surface is provided with semicircular positioning convex.

The utility model with consecutive roots group's positive pole and the negative pole connector by the structure densification couple together make all utmost point groups series connection, this structure make the internal resistance of storage battery little, low in energy consumption, increase power output; Be provided with the plastics pecten between the top at the pole plate two ends in the utmost point group and the bus-bar, can prevent that part from sinking to causing short circuit, perhaps foreign body damages dividing plate, reaches the protection battery, reduces the purpose of self-discharge of battery; And the cell wall of the groove that cooperates with battery case around the middle cover bottom surface is provided with semicircular positioning convex, has increased the sealing effectiveness of battery, and when production operation, the solution in the battery case can be not excessive, saved raw material and man hour of labour.

The utility model is low in energy consumption, power output is big, and once the mileages of continuation of charging increases, and battery sealing-performance is good, long service life, and production technology is simple, does not increase production cost.

Embodiment

As shown in Figure 1, a kind of storage battery of low consumption good airproof performance, comprise battery case 1, place a plurality of single lattice utmost point group 2 that battery case 1 inside separates by dividing plate 3 and the middle cover 4 that cooperates with battery case 1, middle cover 4 is provided with cover plate 5, be provided with some pole plates 9 in the utmost point group 2, positive negative bus 7, battery case 1 inner two consecutive roots groups 2 just, be connected with the connector 6 of the structure densification of " several " font between the negative bus 7, the end span frame is on dividing plate 3 on the connector 6, the brace of two ends arcuation respectively with dividing plate 3 both sides utmost point groups 2 just, negative bus 7 links together, make utmost point group 2 be together in series, this structure makes the internal resistance of storage battery little, and power loss is low.

As shown in Figure 2, be provided with plastics pecten 10 between utmost point group 2 internal polar plates, 9 tops and the bus-bar 7, this plastics pecten 10 can adopt PVC plastics pecten; can prevent that part from sinking to causing short circuit; perhaps foreign body damages dividing plate, reaches the protection battery, reduces the purpose of self-discharge of battery.The structure of plastics pecten 10 as shown in Figure 3.

As shown in Figure 4, the cell wall of the groove that cooperates with battery case 1 around middle cover 4 bottom surfaces is provided with semicircular positioning convex 8, when being buckled in middle cover 4 lids on the battery case 1, positioning convex 8 is squeezed, make middle cover 4 and battery case 1 cooperate the back smooth all around, increased the sealing effectiveness of battery, simultaneously when production operation, solution in the battery case 1 can be not excessive, saved raw material and man hour of labour.
