Embodiment
Referring to Fig. 1, this figure is according to the circuit box schematic diagram with supply unit of backup battery of the present utility model.Main concept of the present utility model is to increase by an auxiliary stand-by power supply in general power supply on vehicle facility.And behind this car ignition trigger, can make between main power source and the stand-by power supply and can charge mutually.
Supply unit with backup battery of the present utility model mainly is made of ignition switch, relay, monostable flipflop, switching device and charging interval control circuit.Yet those of ordinary skills can suitably modify under notion of the present utility model and spirit.
Please join the supply unit with backup battery 100 shown in Figure 1, this supply unit has main power source 102 and backup battery 112, and has positive terminal and negative pole end separately, and it is "+" and "-" in addition that this positive terminal and negative pole end mark in the drawings divides.
One end of ignition switch (ignition) 104 is coupled to the positive terminal of main power source 102, in order to when ignition switch 104 conductings (promptly closing), starts automobile-used main power source 102.This ignition switch is mechanical switch (mechanical switch) normally.First end of relay (relay) 106 is coupled to the positive terminal of main power source 102, and its second end is coupled to the positive terminal of backup battery 112, and this relay 106 also has one the 3rd end.Monostable flipflop 108 couples with first end of relay 106, accepts the power supply of backup battery 112 and works, and export a triggering signal Vt, and this triggering signal as shown in Figure 2.This triggering signal is used for the conducting of control switch Q and closes.
The end of switching device Q and the output of monostable flipflop 108 couple, and the other end then couples with the 3rd end of relay 106, and switching device Q can utilize bipolar (bipolar) transistor or metal-oxide semiconductor (MOS) (MOS) transistor to realize.Switching device Q is according to triggering signal Vt during conducting, makes electric current flow through induction coil in the relay 106, makes switch in the relay 106 be subjected to the induction of induction coil and closes, thereby make charging mutually between main power source 102 and the backup battery 112.Charging interval control circuit 110 is coupled to monostable flipflop 108, in order to the ON time of control switch device Q, with the time of charging mutually between decision main power source 102 and the backup battery 112.Charging interval control circuit 110 can be the RC circuit that is made of resistance and electric capacity, and decides the time of mutual charging between main power source and the backup battery by the numerical value of adjusting resistance and electric capacity.
When thereby ignition switch 104 is closed startup main power source 102, monostable flipflop 108 is started working and is produced triggering signal Vt, and the pulse bandwidth t of this triggering signal Vt (unit is the time) can be decided by the resistance in the aforesaid charging interval control circuit 110 and the numerical value of electric capacity.This pulse bandwidth t is the time of charging mutually between main power source 102 and the backup battery 112.
When triggering signal Vt is high level by low transition, just can be with transistor Q conducting as switch.At this moment, therefore the induction coil in the relay 106 just has electric current to pass through; Simultaneously, the switch in the relay 1 06 just is subjected to the induction of induction coil and cuts out, make between main power source 102 and the stand-by power supply 112 in parallel, thereby make charging mutually between main power source 102 and the backup battery 112.When triggering signal Vt is converted to low level by high level, as above-mentioned principle, just main power source 102 and stand-by power supply 112 off-lines finish charging mutually.
See also Fig. 3, this figure is the operating process schematic diagram with supply unit 100 of backup battery of the present utility model.
Be described in conjunction with Fig. 1.At first,, start main power switch, as opening by the ignition switch of automobile in step 120.Then, in step 122, monostable flipflop 108 is started working, thereby produces a triggering signal Vt.In step 124, according to this triggering signal Vt, control the switch Q in the supply unit with backup battery of the present utility model and make it conducting, thus starting relay 106.
After relay 106 starts, just that main power source 102 is in parallel with stand-by power supply 112 in step 126, and make it mutual charging.Then, in step 128, according to this triggering signal Vt, Q closes with switch, makes main power source 102 and stand-by power supply stop charging.Aforesaid triggering signal Vt can be a pulse signal, utilizes its pulse duration to come the ON time of control switch Q, that is main power source 102 and stand-by power supply time of charging mutually.
Therefore, because behind each startup main power source 102, stand-by power supply 112 just charges mutually with main power source 102.Therefore, when main power source 102 lost efficacy, stand-by power supply 112 just can be in parallel with main power source 102, and to its charging.Therefore, can improve the shortcoming and inconvenience of the power supply facility of existing use single power supply.
In sum, compared with prior art, the supply unit with backup battery of the present utility model has following advantage and effect at least:
Supply unit with backup battery of the present utility model has been set up a stand-by power supply, and when starting main power source at ordinary times, just can charge mutually with main power source.
Supply unit with backup battery of the present utility model has been set up a stand-by power supply, when primary source failure, just can be immediately and the main power source charged in parallel, thus car is started.
The simple circuit element of supply unit utilization with backup battery of the present utility model reaches the purpose that control stand-by power supply and main power source charge mutually.
In sum; though the utility model is disclosed as above by preferred embodiment; yet the foregoing description is not in order to limit the utility model; those of ordinary skills are under the situation that does not break away from spirit and scope of the present utility model; can carry out various changes and retouching to it, therefore protection range of the present utility model should be as the criterion by limiting of appended claim.
