Abstract
A kind of lead-acid battery lid, including covering greatly, be loaded on the exhaust cap of big lid upper right, between big lid, exhaust cap, space is formed with battery labyrinth channel；Being provided with battery terminal installing hole on the left of described big lid, be provided with more than one liquid filling hole on the right side of big lid, liquid filling hole is provided around keeping off acid plate；Being provided with more than one steam vent on the right side of described exhaust cap, steam vent is distributed in away from battery terminal position of mounting hole.This reality have novel have anti-overflow acid structure, vent strip acid phenomenon can be prevented effectively from, and the excessive acid that can accelerate edge, labyrinth is back in battery case.
Description
Technical field
This utility model belongs to battery technology field, relates to a kind of lead-acid battery lid.
Background technology
Lead-acid accumulator is typically made up of multiple battery cell, equipped with sulfuric acid electrolyte in each battery cell, uses process
In require accumulator smooth gas discharge, and acid solution backflow is rapidly, the purpose of the acid that reaches to avoid to overflow.To this end, battery cap is designed with
Steam vent, acid adding hole and return port, and the structure such as surrounding labyrinth to be arranged, gear acid plate is to reduce the loss of electrolyte.Reasonably
Anti-overflow acid structure can reduce the excessive probability of acid solution and avoid the corrosion to vehicle thus resulted in.
In in the past design, big model lead-acid accumulator is relatively big because of overall dimensions, lid steam vent, liquid filling hole, return port,
Labyrinth and dams setting are unreasonable.Problems with the most easily occur: a. steam vent layout is unreasonable, accumulator aerofluxus is obstructed
And vent strip acid；B. liquid filling hole is excessive, causes accumulator in use owing to vehicle vibration and charging easily cause acid solution
Spill over and cover greatly inside, increase battery leakage risk.C. return port is too small, or labyrinth design passage is long and narrow, causes liquid to reflux
Not smooth, easily it is detained in passage, increases battery leakage risk.
Need a kind of reasonably structure of design for this, scientific design steam vent, liquid filling hole, return port and barricade, for acid solution
Backflow and aerofluxus unobstructed passage is provided, reduce battery leakage risk.
Summary of the invention
This utility model is used for overcoming the defect of prior art to provide a kind of big model plumbic acid with anti-overflow acid structure
Battery cap, it is to avoid vent strip acid.
Technical solution of the present utility model is: include the exhaust cap covering greatly, being loaded on big lid upper right, great Gai, row
Between gas lid, space is formed with battery labyrinth channel；It is provided with battery terminal installing hole on the left of described big lid, on the right side of big lid, is provided with one
Above liquid filling hole, liquid filling hole is provided around keeping off acid plate；Being provided with more than one steam vent on the right side of described exhaust cap, steam vent is distributed in
Away from battery terminal position of mounting hole.
Described labyrinth channel is funnel structure.
Described liquid filling hole is six, and described steam vent is two.
Described gear acid plate is provided with opening.
A kind of big model lead-acid battery lid with anti-overflow acid structure, is made up of big lid and exhaust cap, big lid and aerofluxus
Lid interface seals, and between big lid, exhaust cap, space forms battery labyrinth channel, big lid, exhaust cap correspondence cell jar body unit
Form single lattice, it is characterized in that: a. steam vent is distributed in away from battery terminal position two single lattice, increases instroke, it is to avoid
Vent strip acid；B. cancelling return port, liquid filling hole takes on backflow effect, reduces big lid perforated area, reduces liquid overflow probability；
The most special labyrinth structure: be circular open gear acid plate at filling opening, effectively prevent acid solution from spilling.Circular open gear acid plate surrounding
For funnel structure, spill acid solution energy quick backflow.Edge, labyrinth is fish bone structure, and bottom is triangular ramp structure, and this is combined
Structure can be prevented effectively from vent strip acid phenomenon, and the excessive acid that can accelerate edge, labyrinth is back in battery case.

Fig. 1 is big lid front view of the present utility model.
Fig. 2 is exhaust cap front view of the present utility model.
Fig. 3 is the A-A sectional view of Fig. 1.
Fig. 4 is the B-B sectional view of Fig. 1.
Detailed description of the invention
In Fig. 1,2,3,4, this utility model is a kind of big model lead-acid battery lid with anti-overflow acid structure, by covering greatly
1 and exhaust cap 2 form, big lid 1 and the heat-sealing of exhaust cap 2 interface, cover greatly 1,2 spaces of exhaust cap form battery labyrinth channels 3,
The corresponding cell jar body unit of big lid 1, exhaust cap 2 forms single lattice, it is characterized in that: a. steam vent 4 is distributed in away from battery terminal
In the single lattice of the two of position, increase instroke, it is to avoid vent strip acid；B. cancelling return port, liquid filling hole 5 is taken on backflow effect, is subtracted
Little big lid perforated area, reduces liquid overflow probability；The most special labyrinth structure: be circular open gear acid plate 6 at filling opening 5, open
The gas that mouth is easy to during battery uses produce is discharged, and effectively prevents acid solution from spilling.Circular open gear acid plate surrounding is funnel structure,
Spill acid solution energy quick backflow.Edge, labyrinth is fish bone structure 7, and bottom is triangular ramp structure, and this composite construction can be effective
Avoid vent strip acid phenomenon, and the excessive acid that can accelerate edge, labyrinth is back in battery case.
