Utility model content
The utility model is intended to solve that power equipment in prior art uses in charging process and the technical problem of the potential safety hazard that produces provides a kind of power equipment that do not affect in charging process to continue to use and safe dual power supply system.
A kind of dual power supply system, comprises main power source and the auxiliary power supply that can discharge and recharge, load, the first gate-controlled switch, the second gate-controlled switch, the solenoid of charging plug and control the first gate-controlled switch and the second gate-controlled switch work;
Described the first gate-controlled switch comprises the first input pin, the first output pin and the second output pin, and described the second gate-controlled switch comprises the second input pin, the 3rd output pin and the 4th output pin;
Described main power source is connected with the first input pin, and auxiliary power supply is connected with the second input pin, and load one end is connected with the second output pin and the 3rd output pin respectively, load other end ground connection; Described main power source is also connected with charging plug by the first input pin and the first output pin;
The two ends of described solenoid are connected with charging plug respectively.
Preferably, described main power source and auxiliary power supply are storage battery.
Preferably, described load is mobile phone, notebook computer or Ipad.
In above technical scheme, by the first gate-controlled switch and the second gate-controlled switch are set, in the time that main power source feed charges, can realize by operating the operating state of the first gate-controlled switch and the second gate-controlled switch the switching of power supply, thereby between main power source charge period, being converted to auxiliary power supply powers, effectively improve the safety in utilization between electric equipment charge period, improved battery serviceability and life-span simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the dual power supply system of a kind of embodiment of the utility model.
Embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, embodiment of the present utility model provides a kind of dual power supply system, comprise main power source 10 and the auxiliary power supply 20 that can discharge and recharge, load 30, the first gate-controlled switch K1, the second gate-controlled switch K2, the solenoid 40 of charging plug 50 and control the first gate-controlled switch K1 and the second gate-controlled switch K2 work;
Described the first gate-controlled switch K1 comprises the first input pin 9, the first output pin 1 and the second output pin 5, and described the second gate-controlled switch K2 comprises the second input pin 12, the 3rd output pin 4 and the 4th output pin 8;
Described main power source 10 is connected with the first input pin 9, and auxiliary power supply 20 is connected with the second input pin 12, and load 30 one end are connected with the second output pin 5 and the 3rd output pin 4 respectively, load 30 other end ground connection; Described main power source 10 is also connected with charging plug 50 by the first input pin 9 and the first output pin 1;
The two ends of described solenoid 40 are connected with charging plug 50 respectively, and one end 13 of solenoid 40 and the other end 14 are connected with charging plug 50 respectively.
In normal operation, the electrical connection of described charging plug 50Bu Huiyu city, solenoid 40 is not worked, now, the first input pin 9 of the first gate-controlled switch K1 is connected with the second output pin 5, and the second input pin 12 of the second gate-controlled switch K2 is connected with the 4th output pin 8, can find out, now main power source 10 is load 30 normal power supplies by the first gate-controlled switch K1, and auxiliary power supply 20 is not worked.
In the time that main power source 10 feeds need to carry out charging operations to it, charging plug 50Yu city is electrically connected, now civil power carries out powered operation by charging plug 50 for solenoid 40, solenoid 40 work produce magnetic force, thereby change the operating state of the first gate-controlled switch K1 and the second gate-controlled switch K2, in such cases, the first input pin 9 of the first gate-controlled switch K1 is connected with the first output pin 1, and the second input pin 12 of the second gate-controlled switch K2 is connected with the 3rd output pin 4; Main power source 10, no longer for load provides operating current, power, thereby proof load 30 can work on and auxiliary power supply 20 continues as load 30 by the second gate-controlled switch K2.Meanwhile, under current state, main power source 10 is by the first K switch 1, the electrical connection of charging plug 50Yu city, is main power source 10 accumulation of energy of charging by civil power.In the dual power supply system of the present embodiment, preferably, described main power source and auxiliary power supply are lithium battery, and described load is mobile phone, notebook computer or Ipad.
Above technical scheme, in the situation that main power source feed charges, when charging plug 50 connects civil power, system can automatically switch to auxiliary power supply and continue as load and power, and auxiliary power supply does not affect the charging operations of main power source at all in the process for load supplying, effectively improve the processing safety that charging limit, energy storage type power consumption equipment limit is used, and can effectively improve the charge-discharge performance of main power source, extended the useful life of main power source.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
