Description

Shell moulded by a kind of drop resistant lead-acid accumulator

Technical field

This utility model is related to a kind of lead-acid accumulator and moulds shell, especially relates to a kind of drop resistant lead-acid accumulator and moulds shell.

Background technology

Lead-acid storage battery outer case is a vitals of lead-acid accumulator, and it is used to hold electrolyte and pole plate group , its many with made by plastics, the service life of direct relation lead-acid accumulator.

Lead-acid storage battery outer case low intensity, and the lead-acid accumulator total quality after assembling is larger, in carrying or placement During, if housing is collided with ground, so that shell is ruptured, thus directly contribute battery scrapping.And be at present Improve the intensity of lead-acid storage battery outer case, generally the material of preparing of lead-acid storage battery outer case is improved, but to material Improve difficulty larger, and effect is not also notable.

Further, since the thickness of pole plate group is generally inconsistent, when insertion is moulded in shell, or it is difficult to insertion, or after insertion It is difficult to ensure that compressing completely with the cell wall of battery case completely, being also easy to produce and rocking thus causing the active substance on pole plate to come off, Importantly, pole plate group, in use for some time it may occur that certain expansion, makes to occur between pole plate and battery case inwall to squeeze Pressure, due to being hard contact between pole plate group and battery case inwall, excessive compression easily cause de- cream or even pole plate group to damage thus Cause battery failures or inefficacy.

For example, application publication number CN 101877389 A, the Chinese patent of Shen Qing Publication day 2010.11.03 discloses A kind of accumulator housing, its internal baffle passing through to interweave in length and breadth is provided with multiple single lattices, the length direction of single lattice and this housing Width overlaps or parallel；The width of single lattice is overlapped or parallel with the length direction of this housing.This accumulator housing It is disadvantageous in that：Structural strength is low, in carrying or placement process, if housing is collided with ground, easily makes shell Rupture；Pole plate group is not easy to install, and installation rear stability is poor, expands rear pole plate group and easily occurs excessively with battery case inwall Extrude and easily cause de- cream or even pole plate group to damage.

Utility model content

This utility model is to solve the problems referred to above existing for the lead-acid storage battery outer case of prior art, there is provided one Kind of structure is simple, and bulk strength is high, is not easily broken, is easy to pole plate group plug-in mounting, be avoided that pole plate group expand with battery case in There is excessive compression in wall, shell moulded by the drop resistant lead-acid accumulator of long service life.

To achieve these goals, this utility model employs the following technical solutions：

Shell moulded by a kind of drop resistant lead-acid accumulator of the present utility model, including housing, be interval with described housing some every Plate, enclosure interior is separated into some separate space by described dividing plate, and described separate space forms battery case, described housing bottom Four corners are provided with cornerite, and the upper end of described cornerite is fixed with strengthening segment, and described strengthening segment wraps up four inclines of housing And fixation of fitting with hull outside face, described strengthening segment spaced surface is provided with some longitudinal reinforcement convex tendons, described battery case edge The relative inwall in shell length direction is provided with one group of clamp structure, resting guide that described clamp structure includes being sequentially connected, Rebound and grip block, the downward-sloping setting of described resting guide, resting guide one end is fixedly connected with battery case inwall, fixing Between the guide plate other end and rebound, it is connected by torsion spring between rebound and grip block, during the non-stress of torsion spring, resting guide, Rebound and grip block are located along the same line.This utility model is provided with cornerite, cornerite energy on four corners of housing bottom The drop resistant performance improving housing plays a protective role, and the upper end of cornerite is fixed with strengthening segment, and strengthening segment can improve the whole of housing Body structural strength, strengthen convex tendon to improve the bulk strength of housing further, by cornerite, strengthening segment and strengthen convex tendon three it Between cooperate, structure simple so that the structural strength of housing greatly improves with drop resistant performance, be conducive to improving housing use Life-span；Battery case is provided with one group of clamp structure along the relative inwall in shell length direction, and clamp structure includes being sequentially connected Resting guide, rebound and grip block, wherein resting guide play guide effect, are easy to pole plate group insertion battery case during assembling In, when pole plate group insertion battery case in when, under the extruding of pole plate group rebound, grip block can be to both sides（I.e. battery case inwall Direction）Expansion, after pole plate group is fully-inserted, in the presence of torsion spring restoring force, grip block can clamp pole plate group, so that pole Plate group is fixed, and due to can relatively rotate between rebound, grip block, grip block can fit clamping pole plate group all the time so as to will not Generation is rocked, and in use, if pole plate group expands, rebound and grip block can be expanded to both sides again, effectively support The expansive force that passive plate group produces, thus avoid causing de- cream even because expanding generation excessive compression and battery case inwall between The problem that pole plate group is damaged.This utility model simple and ingenious structure, is easy to battery assembling, good using motility, can prevent pole plate Group causes, because expanding generation extruding and battery case inwall between, the problem that de- cream or even pole plate group are damaged, and is conducive to extending battery Service life.

Preferably, described strengthening segment, cornerite and reinforcement convex tendon are homogeneity integrative-structure.

Preferably, the downward-sloping angle and battery case inwall between of described resting guide is set to 10 ~ 30 °.

Therefore, this utility model has the advantages that：

（1）By cornerite, strengthening segment and strengthen cooperating between convex tendon three, structure simple so that the knot of housing Structure intensity is greatly improved with drop resistant performance, is conducive to improving housing service life；

（2）Battery case is provided with one group of clamp structure along the relative inwall in shell length direction, and clamp structure is included successively Connected resting guide, rebound and grip block, resting guide is easy in pole plate group insertion battery case, and grip block can be fitted all the time Clamping pole plate group is rocked so as to will not produce, and can avoid excessively crowded because occurring between the expansion of pole plate group and battery case inwall simultaneously Press and cause the problem that de- cream or even pole plate group are damaged.
