Abstract
An automatic switching device of a notebook emergency power supply comprises a controller, a diode, a relay, a battery pack, a charger, and a notebook; and is characterized in that: the diode and the relay are arranged inside the controller; a cathode of the notebook, a cathode of the charger, a cathode of the battery pack, and one end of an electromagnetic coil of the relay are in parallel connection; the anode of the notebook and a common port of the relay are in connection; an anode of the diode, a normally-open end of the relay, an anode of the charger, and the other end of the electromagnetic coil of the relay are in parallel connection; and the cathode of the diode, a normally-closed end of the relay, and the anode of the battery pack are in parallel connection. When the electric power is on, one path of electric energy of the charger supplies power to the battery pack through the diode; and the other path reaches the electromagnetic coil, the electromagnetic coil is closed, and the electric energy is supplied by the normally-open end to the notebook through the common port. When the electric power is off suddenly, the electromagnetic coil is de-energized, the normally-closed end of the relay resets, and the electric energy of the battery pack supplies electricity to the notebook through the normally-closed end. The above operation is carried out in cycles.
Description
Technical field
The utility model relates to a kind of power switching device for notebook computer, is a kind of notebook stand-by power supply automatic switching control equipment concretely.
Background technology
The supporting battery capacity of notebook is little, and supporting time is short, in case mains failure, under the long-time state of continuous operation, notebook is by not competent as the designer.
Summary of the invention
The utility model purpose is to provide a kind of notebook stand-by power supply automatic switching control equipment, has between civil power and battery pack and switches voluntarily, and the effect of power supply is provided to provide for a long time for notebook.
The utility model is realized with following technical scheme: a kind of notebook stand-by power supply automatic switching control equipment is comprised of controller, diode, relay, battery pack, charger, notebook.It is characterized in that, the inside of controller is equipped with diode and relay, the negative pole of the negative pole of notebook, the negative pole of charger, battery pack, the one end four end parallel connections of the solenoid of relay, the positive pole of notebook is connected with the common port of relay, the other end four end parallel connections of the positive pole of the anode of diode, the Chang Kaiduan of relay, charger, the solenoid of relay, the positive pole three end parallel connections of the negative electrode of diode, the normal-closed end of relay, battery pack.
Civil power has under electric state, and electric energy one tunnel of charger is through diode to the battery pack makeup energy, and another road arrives solenoid, and the solenoid adhesive provides electric energy through common port to notebook by the normal beginning;
When civil power has a power failure suddenly, the solenoid dead electricity, the normal-closed end of relay resets, and the electric energy of battery pack is powered to notebook through normal-closed end;
Civil power when energising, the electric energy of charger return to again a road through diode to the battery pack makeup energy, another road arrives solenoid, the solenoid adhesive provides electric energy through common port to notebook, so circulation by the normal beginning.
The beneficial effects of the utility model: adopt said structure, have between civil power and battery pack and switch voluntarily, the function of power supply is provided to provide for a long time for notebook.
