Abstract
The invention relates to a charging device comprising a battery, a transformer, a controller, a comparator, and a connector. The transformer is used for adjusting the output voltage value of the battery in order to match the battery with an electric device. The controller is used for controlling the battery to output power. The comparator is used for detecting the difference value between the positive end and the negative end of the power of the connector. The batter, the transformer, and the controller are connected in series. The transformer is arranged between the battery and the controller. The comparator is connected in series between the controller and the connector. The controller is connected between the transformer and the connector. When the electric device is connected, the charging device automatically detects the electric device and outputs voltage.
Description
Technical field
The present invention relates to a kind of charging device.
Background technology
Charging device is numerous in the market, utilize battery by boosting or step-down chip charge to electronic equipment, charging device access time have need activate power supply by button.What have has automatic monitoring function, does not need button to activate, but load detecting chip price is expensive, and cause product cost too high, profit is low, does not have the market competitiveness.
Summary of the invention
The object of the present invention is to provide and a kind ofly there is Auto-Sensing and the charging device of cut-in voltage.
For realizing aforementioned object, the present invention adopts following technical scheme: a kind of charging device, it comprise a battery, in order to the output voltage values that adjusts battery with the transformer mated with power consumption equipment, carry out in order to control battery power supply output a controller, in order to detect a comparator and a connector of the positive/negative difference of power supply on connector, described battery, transformer and controller are cascaded, described transformer is between battery and controller, described comparator is connected between controller and connector, and controller is connected between transformer and connector.
Charging device of the present invention is when power consumption equipment accesses, and Auto-Sensing cut-in voltage, bring the facility in use for user, and significantly saves user's time, promotes working efficiency, comparator low price, reduces product cost.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of charging device of the present invention.
Embodiment
Refer to shown in Fig. 1, charging device 100 of the present invention, charge in order to give power consumption equipment 200, it comprises battery 10, transformer 20, controller 30, comparator 40 and an a connector 50, battery 10, transformer 20 and controller 30 are cascaded, and transformer 20 is between battery 10 and controller 30, and comparator 40 is connected between controller 30 and connector 50, controller 30 is connected between transformer 20 and connector 50, connector 50 in order to be connected power consumption equipment 200.
When connector 50 is connected with power consumption equipment 200, comparator 40 first can detect the positive/negative difference of power supply on connector 50, export high/low level to connector 50, utilize this level as the access decision mechanism of power consumption equipment 200, then, wake controller 30 pilot cell 10 up and carry out power supply output, transformer 20 pairs of output voltage values adjust, and magnitude of voltage is mated with power consumption equipment 200.
Charging device 100 of the present invention is when power consumption equipment accesses, and Auto-Sensing cut-in voltage, bring the facility in use for user, and significantly saves user's time, promotes working efficiency, comparator low price, reduces product cost.
Although be example object, disclose the preferred embodiment of the present invention, but those of ordinary skill in the art will recognize, when not departing from scope and spirit of the present invention disclosed in appending claims, various improvement, increase and replacement are possible.
