Abstract

The utility model discloses an accumulator with low consumption and good seal, which comprises a battery jar, a plurality of electrode groups and a middle cover, wherein the electrode groups are arranged in the battery jar and are separated by clapboards, the middle cover is matched with the battery jar and a cover plate is arranged on the middle cover. A plurality of electrode plates, a positive tier bus and a negative tier bus are arranged in the electrode groups; a connecting piece in a shape like the Chinese character 'ji' is arranged between two adjacent electrode groups in the battery jar; the upper end of the connecting piece is bridged on the clapboard; connecting sheets are respectively connected with the positive tier bus and the negative tier bus of the electrode groups at both sides of the clapboard, both ends of the connecting sheets are in arc shapes; plastic pecten plates are arranged between the upper parts of the electrode plates and tier bus; semicircular-shaped positioning convexities are arranged at the periphery of the bottom surface of the middle cover and the groove wall of a notch which is matched with the battery jar. The utility model has the advantages of low power consumption, large output power, good sealing performance of batteries, long service life and simple manufacturing technique. Continuous mileage charged once is increased and the production cost is not increased.

Description

A kind of storage battery of low consumption good airproof performance

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, about 40～the 45Km of the continuation mileages for one time charging of this battery, useful life was at 6～8 months, and battery under normal circumstances useful life should be at 15～18 months, 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.

Summary of the invention

The utility model provides a kind of storage battery of low consumption good airproof performance, compares with existing battery, and this battery has the ability of high-power output, and once Chong Dian mileages of continuation is long, long service life, and product processes is simple, nor can increase production cost.

A kind of storage battery of low consumption good airproof performance, 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.
