Background technology

Lead accumulator is made up of some single lattice batteries, electrolyte solution, battery container, loam cake, bus-bar, groove dividing plate.

Generally, storage battery is in series by 3 or 6 single lattice batteries, and every single lattice cell voltage is about 2V,

Be connected into 6V or 12V to power to power consumption equipment.Single each single lattice of lattice battery all have identical structure.They are by the positive and negative pole plate of alternately placing and be placed on the barrier film that pole plate central authorities are adsorbed with electrolyte solution and form, sometimes for increasing battery capacity, the positive and negative pole plate of multi-disc is composed in parallel positive and negative pole plate group respectively, form a single lattice battery by the positive/negative plate group again.

The special-purpose sealed lead acid storage battery housing of electric motor car in the market, the lead accumulator of thinking 2 * 3 grooves is the existing lead accumulator internal structure of example introduction, 7 positive plates and 8 negative plates are respectively arranged in 6 grooves of battery, each positive/negative plate is alternately arranged, barrier film is housed between pole plate, bus-bar is a positive plate group with 7 positive plate parallel connections in the same groove, 8 negative plates are formed a negative plate group, a positive plate group and a negative plate group that the polar biased post will lay respectively in adjacent two grooves constitute a single lattice battery, bus-bar is cascaded single lattice power supplys all in the battery container again, form the battery of an integral body, the anode and cathode terminals of bus-bar is drawn the both positive and negative polarity of integral battery door.But the height of the bus-bar of existing lead accumulator is lower than the height of the dividing plate of battery container and groove, such structure makes that the bus-bar in each groove is separated from one another, and after in battery container, pouring into electrolyte (being generally sulfuric acid), the bus-bar long period of soaking is in electrolyte solution, electrolyte has corrosiveness to bus-bar, thereby has reduced the life-span of battery, adopts the polar biased post that the bus-bar of each groove is connected, increase non-accumulate consumption of lead, increased production cost.On the other hand, because bus-bar is lower than the height of battery container and groove dividing plate, restricted the height of pole plate, thereby reduced the area of pole plate, make that the capacitance of battery is less, to such an extent as to need more Plante-type plate to form the battery of regulatory specifications, for example, existing lead accumulator needs 15 * 6 pole plates, forms the battery of 12V10AH; The positive and negative electrode of traditional lead accumulator has metal terminal to draw, and needs with workpiece such as screws with its place in circuit the installation procedure complexity in the electric motor car being assembled to.

The utility model content

Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of longer service life, production cost is low, battery capacity is bigger, easy-to-install orthoscopic electromobile battery.

The technical solution adopted in the utility model is such: comprise battery container 1, groove dividing plate 3, loam cake, positive plate 7, negative plate 8, electrolyte solution, bus-bar 2, one group of positive plate 7 and one group of negative plate 8 of wherein alternately placing constitute single lattice power supply, bus-bar 2 is connected all single lattice power supplys successively, it is characterized in that bus-bar 2 exceeds the height of battery container 1 and groove dividing plate 3.

Preferably, the positive terminal on the bus-bar 5 is connected with lead 4 respectively with negative terminal 6.

Preferably, be attached with epoxy resin film on the described bus-bar 2.

Preferably, described battery container has 6 grooves that are arranged in parallel, and is distributed with 3

positive plates

7 and 4 negative plates 8 in each groove, and barrier film is arranged between adjacent plate, described positive plate 7 and negative plate 8 cross arrangements.

Preferably, described battery container has 6 grooves that are arranged in parallel, and wherein in non-conterminous 3 grooves 4 positive plates 7 is arranged respectively mutually, and another group has 5 positive/negative plates 8 respectively in non-conterminous 3 grooves mutually, and barrier film is arranged between adjacent plate in the groove.

In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:

1, bus-bar exceeds battery container, under the condition of battery container constancy of volume, for electrolyte solution and pole plate have been reserved more space, can pour into more electrolyte solution on the one hand, can increase the height of pole plate on the other hand, thereby increase the area of pole plate, increase the capacity of battery; The battery that can form regulatory specifications with still less Plante-type plate, with the modest battery of 12V10AH, adopt design of the present utility model after, only need 42 Plante-type plates.

2, the bus-bar in the utility model is not immersed in the electrolyte solution, adopts epoxy resin film that bus-bar is wrapped up simultaneously, has effectively prevented the corrosiveness of electrolyte solution to the metal bus-bar, has increased the useful life of battery.

3, the both positive and negative polarity of battery is drawn by lead, when easy to use with the battery place in circuit.
