Description
Technical field
The utility model relates to a kind of Hall intelligence cut-off switch system, belongs to control circui device technical field.
Background technology
Current, rechargeable battery is widely used in every field, but the problem that overcharges of rechargeable battery is also more serious, overcharge the life-span of problem meeting serious curtailment rechargeable battery, the accidents such as the fire caused by overcharging also increase day by day, although built-in automatic limiting charging system in part portable power source, but limit is filled in process and still can not be cut off the electricity supply, rechargeable battery problems of excessive heat still can not get solving, and in majority, large-scale charging device (storage battery etc.), the control switch applied all needs manual control (such as CN202794902 utility model patent), there is no overfill-limiting device, the safety problem caused thus and waste of human resource are also difficult to solve more.
Utility model content
Technical problem to be solved in the utility model be provide a kind of for above-mentioned existing issue and can realize plug and play, intelligence is cut off the electricity supply, prevent from overcharging overheated, to save manpower intelligent cut-off switch system.
The technical scheme in the invention for solving the above technical problem is:
Hall intelligence cut-off switch system, comprises a Hall element, a transistor amplifier, an inductance, an electromagnetic relay, a resistance and two power supply external interfaces; The model of described electromagnetic relay is DS2Y-S-DC5V;
Be connected with power supply to be rushed by one of them pin of inductance, another pin is connected with the pin 4 of electromagnetic relay; The pin one of electromagnetic relay is connected with the collector electrode c of triode, and the pin one 6 of electromagnetic relay is connected with the negative pole of transformer with pin one 1; The emitter e of triode is connected with transformer positive pole, and base stage b is connected with the Out pin of Hall switch, and the Vcc pin of Hall switch is connected with transformer positive pole, and the GND pin of Hall switch first connects a resistance and is connected with transformer negative pole by resistance.
The model of described Hall element is 3144E, and the model of described three pipe amplifying circuits is S8050D331, and the inductance value of described inductance is 10mh, and the resistance value of described resistance is 270 Ω.
Whole power-down switching device simple and convenient, assembling process is easily understood.
During charging, charging current is comparatively large, and inductance produces larger magnetic field and makes Hall element conducting, and electromagnetic relay keeps path, and circuit is in connected state; Be full of rear charging current to reduce, and then the magnetic field that inductance produces reduces, Hall element is closed, and electromagnetic relay switch open circuit, circuit cuts off automatically, reaches the object of intelligent power-off.
It utilizes the character of Hall switch electromagnetic conversion, reaches the object of intelligent control circuit.Specifically comprise when the circuit is on, portable power source charges, and electromagnetic relay pin interface 4,11 connects, and has electric current in inductance, so produce magnetic field have effect to Hall element, Hall element is only connected with R1 shape loop, and has electric current to pass through.After charge power supply is full of, electric current is zero, so do not have electric current not act on Hall element in inductance; so; the trigger upset of Hall element inside, disconnects the connection with R1, turns to and form loop with electromagnetic relay and triode; and pin interface 1,16 connects all the time in electromagnetic relay; and be connected to magnet between 1,16, now there is the electric current after triode amplifies to pass through, so produce magnetic, interface 4,11 is disconnected; so charging circuit disconnects, protect portable power source.
The utility model utilizes Hall effect that Hall effect, relay and triode amplification acting in conjunction can be used to carry out intelligent power-off when charging device charging complete.
The present invention can obtain following beneficial effect:
1, all more common and technology of various original papers used in this device is now all with maturation, and cost is all very low, has good economic benefit, also can be esthetically acceptable to the consumers if be generalized on market.
2, volume of switch is less, and assembling process simple and convenient, it is contained in plug and play in charging circuit, can reach conveniently object.
3, there is this switch can well avoid because the overcharged accident caused in charging circuit, not only protected electronic product to be filled simultaneously but also prevent the generation of accident.
4, this product is intelligent power-off completely, does not need manual power-off, eliminates trouble, for people provide convenience, relievedly can use, there is not potential safety hazard, be popular once promotion conference.
Accompanying drawing illustrates:
Fig. 1 charging circuit figure;
Fig. 2 connection layout in kind;
Fig. 3 electromagnetic relay cut-away view
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
Embodiment:
As Fig. 1:
When the circuit is on, source to be charged charging, DS2Y-S-DC5V electromagnetic relay interface 4,11 used connects, electric current is had in the inductance of 10mh, so produce magnetic field have effect to 3144E Hall element, 3144E Hall element is only connected with the resistance R1 of 270 Ω formation loop, and has electric current to pass through.Before testing, test is after charge power supply is full of, electric current is zero, so when there is no electric current in 10mh inductance after charge power supply is full of, 3144E Hall element is not acted on, so, the trigger upset of 3144E Hall element inside, thus disconnect the connection with the resistance R1 of 270 Ω, turn to and DS2Y-S-DC5V electromagnetic relay, S8050D331 triode forms loop, now because the electric current by Hall switch is less, so by S8050D331 triode by Current amplifier, thus make interface 1 in DS2Y-S-DC5V electromagnetic relay, 16 indirectly magnet produce magnetic effect, make interface 4, 11 disconnect, so charging circuit disconnects, protect portable power source.
The cut-away view of electromagnetic relay as shown in Figure 3.
