Specific embodiment
With reference to the accompanying drawing, the present invention is further described.
As shown in Figures 1 to 4, a kind of Plumbic acid accumulator container that resistance to pressure is strong, Plumbic acid accumulator container are by the outer of cube
The open groove body in the top that shell 1 surrounds.
Outer housing 1 includes the shell side at surrounding four sides and the bottom edge of bottom, and shell side is that the main pressure-bearing surface of groove body is also expansion
The generating surface of deformation, bottom edge are the main weight-bearing surfaces of groove body.
Uniform multiple unit grooves are separated by longitudinal baffle 3 and 4 vertical interlaced of lateral partitions in groove body, unit groove is used for
Electrode assembly, electrolyte etc., such as the Plumbic acid accumulator container of currently used 6-evf-70,6-evf-60 model are placed, by one group
Longitudinal baffle 3 and two groups of lateral partitions 4 are divided into six cells of two column, three row.The both ends of longitudinal baffle 3 and lateral partitions 4
It is fixedly connected with the inner wall on 1 respective shell side of outer housing, the inner wall on 1 bottom edge of bottom and outer housing is fixedly connected, 3 He of longitudinal baffle
Lateral partitions 4 form unit groove, while playing the role of support reinforcing to the shell side of outer housing 1, can effectively reduce shell side middle area
The expansion deformation in domain, increases the resistance to pressure of Plumbic acid accumulator container to a certain extent.
The top of outer housing 1 is the closing lid portion 2 for agreeing with top cover for lead-acid accumulator (being not drawn into figure), closing lid portion 2
Outer wall concaves compared with other regions of outer housing 1, i.e. the thickness in closing lid portion 2 is slightly less than the thickness in 1 other regions of outer housing.
The horizontal rib circle 5 that multiple groups uniform intervals arrange is set on 1 inner wall of outer housing, and horizontal rib circle 5 is by being arranged in shell
Horizontal rib on the inner wall of side joins end to end composition, and wherein the horizontal rib circle 5 of the top is longitudinal close to the top in closing lid portion 2
Horizontal rib circle 5 of the top of partition 3 and lateral partitions 4 with the top is in same level.Above structure be arranged so that
Longitudinal baffle 3 or lateral partitions 4 and corresponding horizontal rib form i shaped cross section, at the same longitudinal baffle 3 or lateral partitions 4 with
The two sides of corresponding shell side junction are offseted by corresponding horizontal rib, fold, and are equivalent to longitudinal baffle 3 or 4 liang of lateral partitions
Side is reinforced, and the resistance to pressure of longitudinal baffle 3 or lateral partitions 4 is improved, and avoids the knots such as electrode assembly of the two in unit groove
It deforms under the extruding of structure, once longitudinal baffle 3 or lateral partitions 4 deform, the electrode assembly in unit groove is caused
It squeezes, the not only related deformation that can cause shell side can also adversely affect electrode assembly quality, performance.In specific implementation,
5 quantity of horizontal rib circle is three groups or more, and particular number is different and different according to Plumbic acid accumulator container model, two-by-two horizontal rib
Enclosing 5 spacing is 30-50mm, and 5 height of horizontal rib circle is 3-10mm.
It is each between adjacent horizontal rib circle 5, between the horizontal rib circle 5 of bottom and the bottom edge of outer housing 1 two-by-two
From the vertical rib 6 that is evenly spaced on of one row's multiple groups of setting, the head and the tail both ends of vertical rib 6 and corresponding horizontal rib or bottom
While be fixedly connected, the vertical rib 6 of adjacent two rows is to be intertwined, the effect of vertical rib 6 be further to shell side into
Row reinforces support, can be greatly lowered between horizontal rib circle 5 two-by-two or region is corresponding between horizontal rib circle 5 and bottom edge
Shell side deforms, and improves resistance to pressure.In specific implementation, with the vertical rib 6 of row, spacing is 15-30mm, vertical rib two-by-two
6 width of item is 3-10mm.
In specific implementation, in order to guarantee that 1 shell side inner wall of outer housing is smooth, the thickness of vertical rib 6 and horizontal rib
Consistency of thickness.
In specific implementation, the section of vertical rib 6 and horizontal rib is rectangle or half elliptic.
Due to 1 shell side outer wall of conventional ophthalmic body be it is smooth, be easily deformed under external impacts, in order to improve its impact resistance
Property, outer housing 1 of the present invention is tiled the irregular bumps that constitute in addition to the outer wall on other region shell sides of closing lid portion 2 by multi-panel convex body 7
Face.
In order to guarantee that groove body own wt does not increase, it is 3-5mm that the thickness and routine on 1 bottom edge of outer housing are consistent；Outer housing
The sum of thickness of vertical 6/ horizontal rib of rib of 1 shell side (non-2 region of closing lid portion)+multi-panel convex body 7+ and 1 wall thickness of conventional ophthalmic body
It unanimously, is 3-5mm, wherein the thickness of multi-panel convex body 7 refers to the thickness in its most thick region.In order to guarantee that outer housing 1 itself is strong
Degree, the wall thickness on 1 shell side of outer housing are greater than the 1/2 of overall thickness, the 1/3-1/ with a thickness of overall thickness of vertical 6/ horizontal rib of rib
2,7 thickness of multi-panel convex body is less than the 1/3 of overall thickness.Due to the shell wall of outer housing 1 be it is non-smooth, it is interior there are certain gap,
So its weight is less than solid smooth outer housing.
Detection discovery is tested through inventor, the pressure-resistant performance of Plumbic acid accumulator container of the present invention is greatly increased, is increased up to
80%-120% increases by 10% or more using the battery actual battery capacity that the Plumbic acid accumulator container assembles.With 6-evf-70 type
For number, its resistance to pressure is tested repeatedly and averagely increases 98%, actual battery capacity averagely can reach 77Ah；With 6-evf-60
For model, its resistance to pressure is tested repeatedly and averagely increases 100%, actual battery capacity average value is 66Ah.
The above only expresses the preferred embodiment of the present invention, and the description thereof is more specific and detailed, but can not be because
This and be interpreted as limitations on the scope of the patent of the present invention.It should be pointed out that for those of ordinary skill in the art,
Under the premise of not departing from present inventive concept, several deformations can also be made, improves and substitutes, these belong to protection of the invention
Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
