Description

A kind of damping type lead-acid accumulator plastic housing

Technical field

A kind of lead-acid accumulator plastic housing is the utility model is related to, more particularly, to a kind of damping type lead-acid accumulator plastic housing.

Background technology

Lead-acid storage battery outer case is for holding electrolyte and pole plate group, and it is how made with vinyon, built in it There are pole plate group and electrolyte, be the important composition part of lead-acid accumulator., can be with after pole plate group insertion battery case for ease of assembling Certain gap between the cell wall of battery case be present, when acid accumulator shakes, pole plate group can produce with battery case inwall Relative motion scrapes so as to produce, and easily causes the active material in pole plate group to drop, the active material that these drop is in electric power storage Positive and negative short circuit of polar is easily caused again after being accumulated in the housing of pond, can not only influence the service life of battery, is also existed great Potential safety hazard.

For example, application publication number CN101877389A, data of publication of application 2010.11.03 Chinese patent discloses one kind Accumulator housing, the accumulator housing, multiple single lattices are provided with by the baffle to interweave in length and breadth inside it, the length direction of single lattice with The width coincidence or parallel of the housing；The length direction of the width of single lattice and the housing overlaps or parallel.The electric power storage When pond housing still has lead-acid accumulator and shaken, pole plate group can produce relative motion with battery case inwall and be scraped so as to produce Wipe, easily cause the active material in pole plate group to drop, make after the active material to drop accumulates in accumulator housing and easily Into positive and negative short circuit of polar, the service life of battery can be not only influenceed, also in the presence of great potential safety hazard.

Utility model content

The utility model is to solve the above mentioned problem present in the accumulator housing of prior art, there is provided Yi Zhongjie Structure is simply ingenious, can be subtracted by reducing lead-acid accumulator vibrations to reduce the mutual scraping between pole plate group and battery case inwall Few active material powder drops, and can effectively trap the powder that drops makes it isolate the damping type for avoiding short circuit from occurring with pole plate group Lead-acid accumulator plastic housing.

To achieve these goals, the utility model uses following technical scheme：

A kind of damping type lead-acid accumulator plastic housing, including housing and by enclosure interior space be divided into some separate spaces every Plate, the separate space form battery case, and the battery trench bottom is provided with the powder trapping block being interwoven by glass, the powder Material trapping block is provided with the limiting bracket for preventing powder trapping block compressive deformation, and the housing bottom is provided with buffer layer, described to subtract Shake layer bottom interval is provided with some damping convex ridges, and the space between the damping convex ridge, which is formed, extrudes groove, in the damping convex ridge Provided with the damping through hole through damping convex ridge.The utility model sets the powder being interwoven by glass to trap in battery trench bottom Block, it is directly entered after being dropped from the active material powder on pole plate in the hole in powder trapping block and carries out trapping so that and pole plate Component separates, and the active material powder for avoiding dropping is accumulated in pole plate group causes short circuit, and powder trapping block is in battery Directly put into after the plastic housing demoulding in battery case, assembling is very convenient；Limiting bracket to controlling plate group insertion depth, Avoid contacting with powder trapping block after in pole plate group insertion battery case and make powder trapping block compressive deformation, influence powder trapping effect Fruit；The vibrations of lead-acid accumulator plastic housing can be greatly reduced by the effect of the dual shock absorption of buffer layer and damping convex ridge, so as to significantly The mutual scraping between pole plate group and battery case inwall is reduced, finally to reduce dropping for active material powder, buffer layer is with subtracting Shake convex ridge is made up of elastic endergonic material, such as foam, elastic caoutchouc；Squeeze when allowing the groove to be used to accommodate damping convex ridge stress to The crimp part of both sides, damping through hole have cushioning effect and energy-absorbing function, can improve the damping effect of damping convex ridge.

Preferably, the powder trapping block is bilayer, it is more than positioned at the hole of the powder trapping block on upper strata and is located at lower floor Powder trapping block hole.Powder trapping block is bilayer, and the powder trapping block hole on upper strata is larger, is easy to powder to rapidly enter In order to avoid powder is blocked, accumulated in powder trapping block, the powder trapping block hole of lower floor is smaller to trap powder completely, avoids it again Dropped out from powder trapping block.

Preferably, the limiting bracket includes the limitting casing that is adapted with battery case inwall of profile and positioned at limitting casing bottom Leg at four, portion corner location, the limitting casing are located at powder trapping block upper surface and crimped with powder trapping block.Due to limit The presence of position frame and leg so that can be contacted in pole plate group insertion battery case after certain depth with limitting casing, in the limit of limitting casing Under the effect of position, the lower end of pole plate group will not be pressed onto powder trapping block so as to avoid powder trapping block from deforming.

Preferably, the both sides stringcourse of the longitudinal section of the damping convex ridge is in arc-shaped, and the longitudinal section of damping convex ridge Top margin width is less than base width.The both sides stringcourse of the longitudinal section of damping convex ridge is in that arc-shaped, good damping effect, and energy are rapid extensive Restore shape；The top margin width in damping convex ridge section is less than base width, and lifting surface area is big, and stress is more uniformly distributed, and is advantageous to improve Damping effect.

Preferably, the both sides base angle of the longitudinal section of the damping convex ridge is set to fillet.

Preferably, the longitudinal section of the damping through hole is equilateral triangle.

Preferably, the damping convex ridge and buffer layer are homogeneity integrative-structure.

Therefore, the utility model has the advantages that：

(1) the powder trapping block being interwoven by glass is set in battery trench bottom, from the active material powder on pole plate Trapping is carried out in the hole being directly entered after dropping in powder trapping block so as to be separated with pole plate component, avoids the active matter to drop Matter powder is accumulated in pole plate group causes short circuit, and powder trapping block is directly put into after the battery plastic housing demoulding in battery case , assemble very convenient；

(2) limiting bracket avoids catching with powder after in pole plate group insertion battery case to the insertion depth of controlling plate group Glomeration contact makes powder trapping block compressive deformation, influences powder trapping effect；

(3) vibrations of lead-acid accumulator plastic housing can be greatly reduced by the effect of the dual shock absorption of buffer layer and damping convex ridge, So as to greatly reduce the mutual scraping between pole plate group and battery case inwall, finally to reduce dropping for active material powder.
