Technical field
The utility model relates to lead storage battery technical fields, more particularly to a kind of lead storage battery grid.
Background technique
Lead storage battery is created to be had more than 100 years so far, the wide range of applications of battery.In recent years, electric vehicle with
Its performance of preferably riding instead of walk, lower storage space requirement and outstanding price advantage are grown rapidly in China, have benefited from this, are stored
Battery industry is also rapidly developed.
Lead-acid accumulator belongs to reversible dc power supply, chemical energy can be changed into electric energy, while can also convert electrical energy into
Chemical energy.Lead-acid accumulator is mainly made of electrolyte, slot cover and pole group, and the electrolyte of lead-acid accumulator is sulfuric acid solution,
Wherein pole group is mainly made of positive plate, negative plate and partition, and partition primarily serves storage electrolyte, the gas compound as oxygen
Body channel, play prevent active material fall off and positive and negative electrode between short-circuit effect.
In storage battery production process, carrier and conductor of the grid as lead plaster, lead plaster only have full-filling on grid
Pole plate could be become after curing and drying, and pole plate is the core of lead-acid accumulator, grid is like skeleton, to entire pole plate
Intensity and service life have direct influence.
Current grid rib is all generally to intersect vertically in length and breadth, and this grid current conduction path is longer, and there are larger
Internal drop, and lead plaster easily because in use process volume change it is uneven due to fall off, cause the deficiency in capacity and service life.
The Chinese utility model patent that Authorization Notice No. is CN202034435U disclose a kind of lead acid accumulator plate grid and
Lead-acid accumulator, the lead acid accumulator plate grid include tab, frame, lateral rib and lengthways of rod, wherein the tab with
Frame is connected, and is located at one jiao of frame, and grid made of the transverse direction rib, lengthways of rod and frame interlock is rectangle.
The Chinese utility model patent that Authorization Notice No. is CN203367422U disclose a kind of grid structure of storage battery and
Battery, the grid structure of storage battery, including frame, the interior grid for being equipped with lateral rib and vertical rib and constituting of the frame
Structure, the frame are equipped with tab, and the lower part of the frame is equipped with the secondary rib parallel with vertical rib, the pair rib
Length is equal to the height of adjacent three rows grid in network.
It is above-mentioned in the prior art, the pole plate of preparation, the binding force between lead plaster and grid is not strong enough, and lead plaster is easy to happen de-
It falls.
Utility model content
The utility model is directed to the deficiencies in the prior art, provides a kind of lead storage battery grid, is prepared into pole plate
Afterwards, the binding force between lead plaster and grid is strong, and lead plaster is not easy to fall off.
A kind of lead storage battery grid, criss-cross transverse direction in the frame and frame surrounded including tab, by frame rib
The node that crosses of rib and vertical rib, the transverse direction rib and vertical rib has outstanding convex to lead storage battery grid two sides
It rises.
Preferably, the protrusion is cylinder.It is further preferred that the cross-sectional area of the protrusion is lateral rib and erects
To the 70%~90% of rib intersection area.
Preferably, the more lateral rib of the frame rib and vertical rib are thick, and the protrusion is in lead storage battery grid thickness
Frame rib is not higher by direction.It is further preferred that the protrusion is lower than frame muscle on lead storage battery grid thickness direction
0.2~0.3mm of item.
Preferably, the cross section of the lateral rib and vertical rib is diamond shape.
Preferably, the frame rib includes upper side frame rib, lower frame rib and two vertical frame ribs, the pole
Ear is set on upper side frame rib, and the upper side frame rib and lower frame rib are equipped with the additional muscle across 1~2 lateral rib
The intersection of item, the additional rib and lateral rib also is provided with the protrusion.
The utility model lead storage battery grid passes through the node setting option lead electric power storage that crosses in lateral rib and vertical rib
Pond grid two sides protrusion outstanding enhances lead plaster and grid so that these protrusions can extend into lead plaster after being prepared into pole plate
Bond strength, keep lead plaster not easy to fall off.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model lead storage battery grid.
Fig. 2 is the structural schematic diagram of the utility model lead storage battery grid.
Fig. 3 is the cross-sectional view in Fig. 2 along the direction A-A.

Specific embodiment
As shown in figures 1-4, a kind of lead storage battery grid, in the frame and frame surrounded including tab 1, by frame rib
The node that crosses of criss-cross lateral rib 5 and vertical rib 6, lateral rib 5 and vertical rib 6 has to chloride plate
Grid two sides outstanding raised 7.The setting of the protrusion 7, after being prepared into pole plate, these protrusions 7 be can extend into lead plaster, enhance lead
The bond strength of cream and grid keeps lead plaster not easy to fall off.
In a preferred embodiment, protrusion 7 is cylinder.It is further preferred that the cross-sectional area of protrusion 7 is cross
To rib 5 and the 70%~90% of vertical 6 intersection area of rib.
Frame rib includes upper side frame rib 2, lower frame rib 3 and two vertical frame ribs 4, and tab 1 is set to top
On frame rib 2.
The more lateral rib 5 of frame rib and vertical rib 6 are thick, for filling lead plaster in frame, in order to influence protrusion 7 not
The coating of lead plaster, protrusion 7 are not higher by frame rib on lead storage battery grid thickness direction.In a kind of preferred embodiment
In, protrusion 7 is lower than 0.2~0.3mm of frame rib on lead storage battery grid thickness direction, and in this way in coated plate, protrusion 7 is unlikely
In too prominent, coated plate process is influenced, while can be enhanced as far as possible and lead plaster so as far as possible by the higher of 7 design of protrusion again
Binding force.
