Description
Technical field
The utility model belongs to the series-parallel conversion equipment of model plane aircraft lithium series battery.
Background technology
Lithium battery and lithium polymer battery are because big, the lightweight advantage of its capacitance becomes the ideal first-selected battery of aeromodelling airplane.But the charging technique requirement of lithium and lithium polymer battery is more than NI-G, Ni-MH battery strictness, especially overcharging resisting electricity ability.At present; being applied in the lithium battery or the lithium polymer battery of connecting on the aeromodelling airplane, is the internal resistance inconsistency by it, even adopt pressure limiting, current-limiting charge also not to have the safeguard protection effect; what often generation lithium or lithium polymer battery had also is not full of, and overcharging of having caused the phenomenon of damage.In addition, from the physics angle analysis, lithium series battery is carried out also science not of serial connection charge.
Summary of the invention
The purpose of this utility model is exactly problem and the defective that exists at above-mentioned prior art, design provides a kind of aeromodelling airplane lithium series battery parallel-series switch device, realize that lithium series battery is when the series connection use needs charging, converting parallel connection to carries out lithium series battery is charged with voltage form, make the inconsistent battery of every joint internal resistance in the unified time, also can both be charged to when dispatching from the factory the magnitude of voltage of regulation, reach guarantee lithium series battery safely, increase the service life, improve the purpose of each batteries charging quality and effect.
Basic design of the present utility model use two cuttves two to refer to change over switch and circuit board making parallel-series switch device, but complex structure is made the processing cost height.The design be with change over switch movably two cutter sheet metals be transformed into directly design this double-layer elastic sheet metal and circuit board changeover contact contact matching on circuit board of double-layer elastic sheet metal, avoided causing the loose contact phenomenon because of the elastic force deficiency, six contacts of former change over switch on circuit board through transforming and design, make contact also reduce to the simplest four contacts, in the change over switch outside the shared socket of battery input and output is set, the shared socket of battery input and output is connected with series-parallel battery contact; The corresponding connection of circuit board changeover contact with battery contact; The change over switch housing is fixedlyed connected with circuit board fixed conversion switch housing hole, so far constitutes aeromodelling airplane lithium series battery parallel-series switch device.The utility model is simple in structure, and volume is little, and is in light weight, cheap for manufacturing cost, easy to use, and charging effect is good.
