Abstract

A storage battery grid belongs to the technical field of storage batteries, which comprises a frame, a handle lug, longitudinal ribs and transverse ribs, wherein the handle lug is arranged at an angel portion of one end of the frame, the longitudinal ribs and the transverse ribs are connected in the frame and are mutually crossed into latticed shape, and at least one angle portion of the frame corresponding to the angle portion equipped with the handle lug forms circular arc. The utility model has the advantages that the grid can increase the capacity of the storage battery through increasing the quantity of the longitudinal ribs and the transverse ribs, and can not increase the quality of the storage battery with identical rated weight because saved materials of the circular arc portion of the frame is used to increase the corresponding longitudinal ribs and transverse ribs.

Description

The grid of storage battery

Technical field

The utility model belongs to the battery technology field, is specifically related to a kind of grid of storage battery.

Background technology

The structure of known grid comprises frame 1, handle ear 2 and longitudinal and transverse rib 3,4 by shown in Figure 1, and handle ear 2 is arranged on a bight of frame 1, and longitudinal and transverse rib 3,4 is bound up on the frame 1 and the latticed structure of longitudinal and transverse rib 3,4 interlaced one-tenth.Longitudinal and transverse rib 3,4 is except being the function that has more delivered current the carrier of lead plaster as active material, the effect that pole plate is reached discharge and recharge; The effect of handle ear 2 is welding pole plates in parallel.

The definition of battery capacity is: use the electric current of setting the voltage given electric weight of battery discharging to setting.We can say that also battery capacity is: with the electric current of setting battery discharging to the time of setting that voltage experienced and the product of this electric current.The unit ampere-hour by Ah represent, the rated capacity of storage battery represents with C, the unit ampere-hour is a discharging current (A) and the product of discharge time (h).At present, people are more and more exquisite to the capacity requirement of storage battery, mainly show as rate when the downward long discharge of prerequisite of not gaining in weight, for example, the battery capacity of an electric bicycle is 10Ah, rate is 2h during discharge, its nominal discharge current be 10Ah divided by 2h, equal 5A, and for example, the battery capacity of the storage battery that automobile starting is used is 54Ah, rate is 20h during discharge, and its nominal discharge current thinks that 54Ah removes 20h, equals 2.7A so, use the current discharge of 5A and 2.7A respectively if that is to say above-mentioned two kinds of storage batterys that exemplify, then should can continue the voltage that 2h and 20h just drop to setting respectively.

Why the applicant will enumerate above-mentioned example, and increase capacity when being intended to and do not gain in weight and can improve the continuous discharge time that prolongs, yet, described in the above and be to satisfy such requirement according to the applicant by the grid of structure shown in Figure 1.

Find through long-term exploration of the applicant, comprise that the structure that in the prior art of Fig. 1 all are applied to the grid of storage battery is irrational, because the vertical rib strip that is positioned at position, handle ear diagonal angle from the air line distance of handle ear farthest, at this position, resistance maximum when the electric current that active material produced transmits by vertical rib strip, so it is better than nothing that the effect in this bight be we can say, has value hardly.So if go to exchange the quantity that increases corresponding vertical rib strip for to remove the bight, can yet be regarded as so is that a kind of capacity that can increase storage battery can embody the good act of not gaining in weight again, technical scheme described below produces under this background.

Summary of the invention

The grid of the storage battery of the weight that task of the present utility model is to provide a kind of capacity that can improve storage battery can not increase storage battery again.

Task of the present utility model is finished like this, a kind of grid of storage battery, it comprises frame, handle ear and longitudinal and transverse rib, the handle ear is arranged on a bight of an end of frame, longitudinal and transverse rib be bound up in the frame and interlaced one-tenth latticed, described frame institute is corresponding at least one bight formation circular arc of an end that is provided with the handle ear.

Handle ear described in the utility model is arranged on the bight of an end of the Width of described frame, and described circular arc be formed in described frame Width the other end bight and constitute angular dependence with described handle ear.

The utility model is owing to adopted technique scheme, can improve the capacity of storage battery by the quantity that increases vertical rib strip, and can not increase the deal of the storage battery of same rated weight, because the material that the arc sections branch of frame saves is used to increase corresponding vertical rib strip.

Fig. 1 is the structure chart of the grid of the storage battery in the prior art.

Fig. 2 is the first example structure figure of the present utility model.

Fig. 3 is the second example structure figure of the present utility model.

Embodiment

Embodiment 1:

Ask for an interview Fig. 2, frame 1 is substantially rectangle, in the present embodiment, frame 1 is a rectangle, promptly receive handle ear 2 by a bight of the upper end of current icon location status in the mode of welding at an end of the Width of this frame 1, the effect of handle ear 2 is welding pole plates in parallel or claims welding linking strip in parallel.In frame 1, connect longitudinal and transverse rib 3,4, the latticed structure of longitudinal and transverse rib 3,4 formations interlaced with each other.Longitudinal and transverse rib 3,4 (attachment of lead plaster) except supporting active material such as lead plaster has more delivered current, makes whole grid have the effect that discharges and recharges.As technical spirit of the present utility model, the left comer portion that is illustrated lower end with a bight of the other end of the Width of frame 1 is designed to circular arc 11, because the existence of this circular arc 11, thereby saved the consumption of rib, also saved lead plaster simultaneously as active material.That is to say it is that the relatively poor part of the terminal active material utilization of grid surface potential is removed, transform the capacity that the quantity that increases vertical rib strip 3 is improved storage battery into the component that removes.For example: the quantity of original vertical rib strip 3 is become 9 by 8, make the sectional area of vertical rib strip 3 obtain rational increase, not only help improving the effect performance of the active material of whole piece of grid bottom, and help to prolong grid by the time of sulfuric acid corrosion, very useful to the useful life that prolongs storage battery.

Embodiment 2:

One end of the Width of frame 1 promptly all is designed to circular arc 11 with two bights that are provided with handle ear 2 corresponding ends, so can more help to increase the capacity of storage battery, the component that is to say the bight at two right angles that remove exchanges the quantity that increases vertical rib strip 3 for, and the quantity that for example makes vertical rib strip 3 becomes 10 by 8 of prior art.All the other are with the description to embodiment 1.

Such scheme can also exchange whole piece grid with the component in the bight of removing for, for example will be contained in changing into by 27 or 29 pieces of utmost point groups that grid constituted in the cavity volume originally by 25 pieces of utmost point groups that grid constituted, only cavity volume is omited to amplify, this scheme can not increase the rated weight of storage battery equally.
