Embodiment
The embodiment to the technical solution of the utility model is described in detail below in conjunction with the accompanying drawings：
According to one embodiment of the application, as Figure 1-3, the multifunction electric bicycle charger of this programme, bag
Transformer, rectifying and wave-filtering voltage-stablizer, switch and battery are included, switch includes first switch, second switch and the 3rd switch, electric power storage
Pond includes the first battery and the second battery.
Transformer output end is connected with rectifying and wave-filtering voltage-stablizer input, and rectifying and wave-filtering output end of voltage stabilizer is respectively with first
Switch and second switch connection, input of the first switch respectively with overcurrent protector and charge controller are connected, overcurrent protection
The output end of device and charge controller is connected with the first battery input.
Second switch is connected with the second battery, the 3rd switch and USB module successively；Second switch and the second battery are defeated
Enter end and the 3rd switch and be provided with charge controller with parallel between USB module output end, and charge controller refers to charging
Show that lamp is connected.
Wherein, the second battery is pressure-adjusting type battery, and its output end is connected with low pressure alarm input, and transformer is
BK-50 controls transformer.
It is sample circuit that low pressure alarm circuit includes being sequentially connected in series with the second accumulator output end, phase inverter, many
Harmonic oscillator and buzzer, wherein adjustable resistance R2 and diode D1 are connected in parallel on the second battery two ends and constitute sample circuit, use
In collection battery tension signal.
The operation principle of low pressure alarm circuit is：
As shown in Fig. 2 when the second battery both end voltage is higher, the second battery tension signal of collection is high level,
After inverted device 4011BD is reverse, the high level voltage signal is converted into low level, now, not had equivalent to multivibrator
Power input, it is impossible to produce oscillator signal, therefore buzzer not sounding alarm.
When cell voltage is relatively low, the second battery tension signal collected is low level, and inverted device 4011BD is anti-
Backward, high level is exported, equivalent to the power input of multivibrator, oscillating circuit produces and exports square-wave signal, buzzing
Device sends the alarm of corresponding frequencies according to the signal of input.
Overcurrent protector circuit include current-sensing circuit, current-sensing circuit output end respectively with screened circuit and shut-off
Circuit input end is connected, and screened circuit and breaking circuit output end are connected with output-stage circuit input.

NOT gate and NOT gate, input one end of NAND gate two are connected with the output end of comparator first, the output end of the other end and delay circuit
Connection.
The operation principle of overcurrent protector circuit is：
As shown in figure 3, the circuit in dashed box A areas is " mask pattern " for current protection, comparator first in screened circuit
The signal VB1 of output obtains VB2, VB1 and VB2 after delay and carries out NOR-operation, then after a NOT gate is reverse, obtains
The output signal VBOUT of screened circuit.
Two signals simultaneously for 1 can only be kept constant by logic or computing, therefore, it can by nor gate and phase inverter
Eliminate the pulse signal in time delay, increase screened circuit in current foldback circuit, then it is maskable fall time delay in
Over-current signal, but if load current is too big, possible moment burns power tube, it is therefore desirable to corresponding breaking circuit.
Dashed box B areas circuit is breaking circuit, and can solve the high current within the shielding time may cause power tube moment to be burnt
The problem of, when occurring very big over-current signal in time delay, the timely switch-off power pipe of energy, it is ensured that system safety.
Idiographic flow：Transformer inputs and the 220V electrical connection that exchanges, and 220V alternating current is reduced to 36V exchange
Electricity, the rectified filtering voltage stabilizer rectification of 36V alternating currents is 36V direct current, closes first switch, then give by overcurrent protector
First battery charges, wherein first switch and charge controller formation feedback control circuit, when in electric vehicle and bicycle first
When battery is fully charged, by feedback circuit, first switch disconnects, and prevents overcharge.
When the first accumulator electric-quantity is not enough, the second battery opens first switch as power supply, then by overcurrent protector
Give the charging of the first battery.
When brownout occurs in the second battery, low pressure alarm pipes, now, and closure second switch can give second
Battery charges, and when the indicator lamp being connected with the second battery is changed into green, illustrates the second battery charging complete, and disconnect
Second switch, wherein second switch constitute feedback circuit with charge controller, and in charging, second switch is closed, when the second electric power storage
During the charging complete of pond, by feedback circuit, second switch disconnects, and prevents the second overcharge of a battery.
It is 5V by the selection of the second battery tension gear, opens the 3rd and switch, is charged by USB interface to extraneous load,
Wherein the 3rd switch constitutes feedback circuit with charge controller, the 3rd switch closure in charging, when electronic equipment is fully charged,
Switched off by feedback circuit, the 3rd, prevent electrical equipment overcharge.
