Description
Technical field
The utility model relates to a kind of charger, relates in particular to a kind of electrical bike charger.
Background technology
At present, electric bicycle has got into huge numbers of families.Because electric bicycle is to lean on a chargeable storage battery and charger to be used as power, therefore, the performance of electrical bike charger and useful life just become the problem that the user is concerned about the most.Charger can give out a large amount of heat in charging process, this just needs good equipment just to dispel the heat, and commonly uses fan, so the length in fan useful life just is directly connected to the useful life of charger.
Summary of the invention
The purpose of the utility model provides a kind of fan useful life of prolonging, and then prolongs the useful life of charger, the electrical bike charger that can cut down the consumption of energy simultaneously.
The above-mentioned technical problem of the utility model mainly is able to implement through following technical scheme: a kind of battery charger; There are fan, transformer, radiator, relay to be connected on the circuit board; Said circuit board is divided into circuit board I and circuit board II, is provided with transformer and radiator on circuit board I and the circuit board II, and fan is from the power taking of circuit board I; The circuit board I be provided with thermistor, the circuit board I is provided with power-sensing circuit; The circuit board I is a main pole, and the circuit board II is time utmost point.Thermistor is induced environment temperature height automatically, makes fan rotate speed and regulates automatically, when ambient temperature is hanged down; The signal of thermistor imports control circuit, and the control fan rotates and slows down, otherwise; When ambient temperature is high; The signal of thermistor imports control circuit, and the control fan rotates to be accelerated, and quickens heat radiation.Power detection when power-sensing circuit is used to charge, when power was big, heat radiation was just many, and temperature is just high, and at this moment, the signal of power-sensing circuit imports control circuit, and the control fan rotates to be accelerated; Power hour, heat radiation is just few, temperature is just low, at this moment, the signal of power-sensing circuit imports control circuit, thus the control fan rotates and slows down.Effectively control the rotating speed of fan, just can prolong the useful life of fan, promptly prolonged the useful life of charger.
The signal of thermistor and power-sensing circuit after control circuit combines two signal synthesis to judge, is controlled the rotating speed of fan for importing control circuit simultaneously.
Fan is from the power taking of circuit board I, and the circuit board I is a main pole, makes the fan running environment more stable, and the heat of heat transformer distributes still less.
As preferably, transformer on the circuit board I and radiator are arranged on the last avris of circuit board I, both near; Transformer on the circuit board II and radiator are arranged on the following avris of circuit board II, both near.
In sum; The utility model compared with prior art has following advantage: the utility model is simple in structure; Thermistor and power-sensing circuit on original charger, have been increased newly; The rotating speed of adjusting fan that can be rationally autonomous prolongs the useful life of fan, and then prolongs the useful life of charger.The fan power taking changes main pole into, makes the fan running environment more stable, and the heat of heat transformer distributes still less.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Label is among the figure: 1, fan, and 2, transformer,, 3, radiator,, 4, the circuit board I, 5, the circuit board II, 6, thermistor, 7, power-sensing circuit.
Embodiment
Below through embodiment,, the technical scheme of the utility model is further specified in conjunction with accompanying drawing:
Embodiment 1:
As shown in Figure 1, a kind of battery charger has fan 1, transformer 2, radiator 3, relay to be connected on the circuit board; Circuit board is divided into circuit board I 4 and circuit board II 5, and the circuit board I is a main pole, and the circuit board II is time utmost point; Be provided with transformer and radiator on circuit board I and the circuit board II; Fan is from the power taking of circuit board I, the circuit board I be provided with thermistor 6, the circuit board I is provided with power-sensing circuit 7; The circuit board I is a main pole, and the circuit board II is time utmost point, and transformer on the circuit board I and radiator are arranged on the last avris of circuit board I, both near; Transformer on the circuit board II and radiator are arranged on the following avris of circuit board II, both near.
The utility model prolongs the useful life of fan through newly-increased thermistor and power-sensing circuit, and the fan power taking changes main pole into, makes the fan running environment more stable, and the heat of heat transformer distributes still less.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
