Abstract
The utility model provides a play to employ high power thin plate bars, includes the frame and is located the perpendicular muscle of frame, horizontal muscle, erect muscle, the perpendicular long rectangle check of horizontal muscle constitution, the interval a between the adjacent perpendicular muscle is the 7 -8 millimeter, and the interval b between the adjacent horizontal muscle is the 13 -14 millimeter. Adopt the closely spaced perpendicular long rectangular muscle skeleton texture of big, the perpendicular muscle of horizontal muscle interval, the perpendicular muscle that constitutes the grid is many and intensive, arranges intensive perpendicular muscle lug connection and goes up the lower frame, is favorable to the quick conduction of electric current, owing to be close to the current density of board ear department and distribute highly, corrode seriously, perpendicular rib that the event will be located board ear lower part is with slightly to improve discharge voltage and capacity value, it is crescent to the middle part by both sides to go up frame height dimensions, can improve electric current bearing capacity and instantaneous discharge final voltage, be directed against voltage distribution characteristics, the geometry of frame on the optimal design in addition to improve electric current bearing capacity, improve instantaneous discharge final voltage.
Description
Technical field
The utility model relates to a kind of accumulator structure part, particularly rises and employs high power thin grid, belongs to battery technology field.
Background technology
Grid is one of basic element of character of lead acid accumulator, accounts for 1/4 of battery gross mass, and its Main Function is the carrier of active material, and active material backup plate grid keep and support; Grid or collector, play electric current conduction and collecting and distributing effect make homogeneous current distribution in accumulator charging/discharging process.The starting multiplying power of lead-acid starter battery is generally 8 ~ 10 multiplying powers of battery capacity.Grid many employings radiation muscle of lead-acid starter battery or the flattened rectangular lattice structure that transverse bar spacing is little, perpendicular muscle spacing is large.The grid of rectangular grid structure, the effect of horizontal bar, mainly as plate active material carrier, erects the effect mainly collector of muscle.
The backup start power supply that high-grade car is equipped with, require that the starting multiplying power of storage battery is 25 ~ 35 multiplying powers i.e. 25 ~ 35C (A) of battery capacity, instantaneous (5S) discharge voltage value can not lower than 7.2V, adopt the grid of above-mentioned two kinds of ordinary constructions, high-multiplying power discharge effect is not very desirable, is difficult to reach designing requirement.For meeting the high request that backup start power supply proposes battery high magnification heavy-current discharge, need to improve the grid structure of existing valve-control sealed lead acid battery.
Utility model content
The purpose of this utility model is the drawback for prior art, provides one can improve the instantaneous high-rate discharge ability of battery, employs high power thin grid to meet rising of high-power battery high magnification instantaneous discharge voltage and time requirement.
The purpose of this utility model is achieved through the following technical solutions:
A kind of rising employs high power thin grid, comprises frame and the perpendicular muscle, the horizontal bar that are positioned at frame, and described perpendicular muscle, horizontal bar form perpendicular long rectangular grid, and the spacing a between adjacent perpendicular muscle is 7-8 millimeter, and the spacing b between adjacent horizontal bar is 13-14 millimeter.
Employ high power thin grid for above-mentioned, the top of upper side frame is provided with plate ear, and the perpendicular muscle being positioned at plate ear bottom is that muscle is erected in the reinforcement of overstriking.
Employ high power thin grid for above-mentioned, described upper side frame height dimension increases gradually by the middle part of two side direction, and upper side frame middle height size c is 3.5-4.5 millimeter, and upper side frame edge height dimension d is 2-2.2 millimeter.
Employ high power thin grid for above-mentioned, the thickness of described grid is 1.1-1.5 millimeter.
The utility model improves grid structure of storage battery for the instantaneous high-rate discharge ability of raising battery: adopt the closely spaced perpendicular long rectangle muscles and bones shelf structure of large, the perpendicular muscle of transverse bar spacing, the perpendicular muscle forming grid is many and intensive, the perpendicular muscle of dense arrangement directly connects upper and lower side frame, is conducive to the quick conduction of electric current; Due to high near plate ear place electric current distribution, seriously corroded, therefore will the perpendicular muscle overstriking of plate ear bottom be positioned at, to improve discharge voltage and capability value; Upper side frame height dimension increases gradually by the middle part of two side direction, can improve current carrying capacity and instantaneous discharge final voltage; In addition for voltage's distribiuting feature, the physical dimension of optimal design upper side frame, thus improve current carrying capacity, improve instantaneous discharge final voltage.The utility model erects the design of muscle, grid frame through optimizing grid, while the current-carrying effective area improving grid, improve the current-carrying rate of grid, reduces current density, ensures instantaneous high-current discharge performance.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, each list of reference numerals is: 1, upper side frame, 2, plate ear, 3, perpendicular muscle, 4, horizontal bar, 5, strengthen perpendicular muscle, 6, left frame, 7, left frame, 8, lower frame.
Embodiment
Referring to Fig. 1, the utility model comprises the rectangular shaped rim be made up of upper side frame 1, left frame 6, left frame 7, lower frame 8, perpendicular muscle 3 and horizontal bar 4 is provided with in rectangular shaped rim, perpendicular muscle, horizontal bar form perpendicular long rectangular grid, spacing a between adjacent perpendicular muscle is 7-8 millimeter, and the spacing b between adjacent horizontal bar is 12-14 millimeter.Said structure makes perpendicular muscle dense arrangement, and each perpendicular muscle directly connects upper and lower frame, is conducive to the quick conduction of electric current.
It is partially thin that grid described in the utility model compares common grid, and the thickness of grid is 1.1-1.5 millimeter.In storage battery use procedure, voltage drop is by battery Resistance Influence, voltage drop is larger just can more near final voltage, the cell resistance of thin plate grid diminishes, voltage drop is little, spacing after assembling is relatively little, electrolyte permeability is faster, and active material utilization improves, therefore can improve the Immediate Stop voltage of heavy-current discharge.
Still referring to Fig. 1, the top of upper side frame 1 is provided with plate ear 2, and plate ear is close to the centre position of upper side frame, because the perpendicular muscle electric current distribution near plate ear place is high, seriously corroded, therefore muscle 5 is erected in the reinforcement that the perpendicular muscle being positioned at plate ear bottom is overstriking, to improve discharge voltage and capacity.
According to the grid in use feature of voltage's distribiuting in fan-shaped distribution centered by plate ear, the height dimension of the utility model upper side frame 1 increases gradually by the middle part of two side direction, as shown in Figure 1, upper side frame middle height size c is 3.5-4.5 millimeter, and upper side frame edge height dimension d is 2-2.2 millimeter.Said structure can improve current carrying capacity, improves instantaneous discharge final voltage.
