Abstract
It include shell the utility model relates to a kind of lead-acid accumulator, it is mounted on the intracorporal pole plate of the shell, the shell includes the parallel lateral surface parallel with the pole plate plate face and the vertical outer face vertical with the pole plate plate face, the parallel lateral surface includes inner and outer wall, and the inner wall is inwardly protruded arcwall face.A kind of lead-acid accumulator mounted inside pressure of the utility model is consistent, improves battery life.
Description
Technical field
The utility model relates to a kind of lead-acid accumulator, especially a kind of lead-acid accumulator shell.
Background technique
The maximum power battery model of volume of production and marketing is 6-DZF-20 on existing market, and such battery is that 6 single batteries press 1
× 6 Structural assignments are composed in series, and the assembling pressure of 1 × 66, structure pole group is finally all reacted on the side wall of two compressions, if
When side wall construction intensity is not enough to support this assembling pressure, battery will bulging, so as to cause the 1st and the 6th single lattice body
Product increases, and the relatively intermediate single lattice of the two single lattice acid contents is more after acid adding takes out acid, causes single lattice acid content to have larger difference, holds
It easily causes single lattice to fall behind, leads to battery premature failure.The existing method for directly thickening compression face wall thickness, can partially alleviate battery
Tympanites degree, but due to the limitation of material cost etc., it is impossible to excessive increase wall thickness, at the same it is inevitable because deforming,
Therefore also without fundamentally solving the problems, such as to improve single lattice consistency.
Summary of the invention
In order to solve the above-mentioned technical problem, it includes shell that the utility model, which provides a kind of lead-acid accumulator, is mounted on institute
State the intracorporal pole plate of shell, the shell includes the parallel lateral surface parallel with the pole plate plate face and vertical with the pole plate plate face
Vertical outer face, the parallel lateral surface includes inner and outer wall, the inner wall be inwardly protruded arcwall face.
Further, the height of projection of the arcwall face is by the middle part of the inner wall around towards the vertical outer face
Direction gradually decrease.
A kind of lead-acid accumulator mounted inside pressure of the utility model is consistent, improves battery life.
Detailed description of the invention
Fig. 1 is the schematic diagram of lead-acid accumulator shell of the utility model (without pole group) a kind of；
Fig. 2 is the schematic diagram of lead-acid accumulator shell of the utility model (equipped with pole group) a kind of.
Specific embodiment
The utility model is described in further detail for specific embodiment with reference to the accompanying drawing.
As shown in Figure 1, 2, a kind of lead-acid accumulator includes shell 10, and the pole plate being mounted in shell 10 (is not shown in figure
Show), shell 10 includes the parallel lateral surface 10b parallel with the pole plate plate face and vertical outer face 10a vertical with pole plate plate face, is put down
Row lateral surface 10a includes inner wall 1 and outer wall 2, and inner wall 1 is inwardly protruded arcwall face, inwardly protruding as inner wall court herein
To the direction of pole plate, the height of projection of arcwall face is preferably gradually dropped towards the direction in vertical outer face by the middle part of inner wall around
It is low.
Before the group of pole, as shown in Figure 1, inner wall 1 to be designed to the arc surface of protrusion, height of projection A, arc radius is
R keeps being plane at outer wall 2, in this way the thickness of design increase side wall, enhances the intensity of side wall.
Be packed into pole group after, as shown in Fig. 2, at inner wall 1 arc surface by pole group pressure influenced, toward external drum after become plane,
Outer wall 2 is deformed into the arc surface that radius is R, outwardly convex, deflection A.The volume of inside battery single lattice can thus be made
Unanimously, to keep each single lattice inside acid content of battery consistent, a possibility that battery list only falls behind is reduced.
A kind of lead-acid accumulator mounted inside pressure of the utility model is consistent, improves battery life.
Claims (2)
1. a kind of lead-acid accumulator, including shell, are mounted on the intracorporal pole plate of the shell, the shell includes and the pole plate plate
The parallel parallel lateral surface in face and the vertical outer face vertical with the pole plate plate face, the parallel lateral surface include inner wall and outer
Wall, which is characterized in that the inner wall is inwardly protruded arcwall face.
2. lead-acid accumulator according to claim 1, the height of projection of the arcwall face is from the middle part of the inner wall to four
The direction in week towards the vertical outer face gradually decreases.
