Abstract
The utility model relates to a notebook PC, in particular to an AC adapter of the notebook PC. Aiming at overcoming the shortcoming that the charge of the battery of the notebook PC is inconvenient, the utility model discloses the AC adapter of the notebook PC, which can separate from the notebook PC to charge the battery. The utility model has the technical proposal that the AC adapter of the notebook PC comprises a power supply circuit and a DC output port. The AC adapter of the notebook PC is characterized in that a charge control circuit and a battery port are included, and the battery port is connected with the charge control circuit which is connected with the power supply circuit. The AC adapter of the notebook PC has the beneficial effect that the charge of the battery of the notebook PC can be performed singly by separating from the notebook PC through adding only a few components and fully utilizing the AC adapter of the notebook PC, and the use convenience is increased.
Description
Technical field
The utility model relates to notebook computer, particularly the notebook computer AC adapter.
Background technology
Notebook computer is a kind of commonplace portable electric appts that uses, and in recent years, along with development of technology, the notebook computer configuration is more and more high, and function is more and more powerful, and the electric energy that needs is also in rising trend.Notebook computer as portable set, its built-in power adopts lithium battery power supply usually, because bigger electric current need be provided, and be subjected to the restriction of configuration aspects, the general volume of cells in notebook computer is bigger, and majority has irregular special shape, and the interface of battery also is not quite similar.The cells in notebook computer of today does not also have general charger, in the standard configuration of notebook computer, is not equipped with charger yet.The charging of cells in notebook computer normally on notebook computer, is finished by the AC adapter of configuration.That is to say that the charging of cells in notebook computer can not break away from notebook computer and carry out separately.This has brought inconvenience to use, particularly has under the situation of a plurality of reserve batteries, and battery must be installed and pull down to charging process repeatedly, and is very loaded down with trivial details.
The utility model content
Technical problem to be solved in the utility model is exactly at the inconvenient shortcoming of cells in notebook computer charging, provides a kind of and can break away from notebook computer, the notebook computer AC adapter that its battery is charged separately.
The utility model solve the technical problem, and the technical scheme of employing is that the notebook computer AC adapter comprises power circuit and dc output end mouth, it is characterized in that, also comprises charging control circuit and battery interface; Described battery interface is connected with described charging control circuit, and described charging control circuit is connected with described power circuit.
The beneficial effects of the utility model are, make full use of the AC adapter of notebook computer, only increase a few components, just can make the charging of cells in notebook computer, can break away from notebook computer and carry out separately, have increased the convenience of using.
Description of drawings
Fig. 1 is the schematic diagram of embodiment.
Embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
The utility model increases charging control circuit in the AC adapter of notebook computer, and according to the interface shape of cells in notebook computer, setting battery interface.Battery interface is connected with power circuit by charging control circuit, and the battery that connects is charged.
For the load of the adapter of not increasing exchanges, a diverter switch can be set, in charging, disconnect the dc output end mouth, or when using the dc output end mouth to power, cut off the power supply of battery interface as notebook computer.
At the various characteristics of cells in notebook computer interface, battery interface can be made the plug shape, and be connected with described charging control circuit by flexible cable, be convenient to be connected with computer battery.
The characteristics of combined type portable equipment, AC adapter of the present utility model, power circuit is selected the switching power circuit that volume is little, efficient is high for use.
Embodiment
As shown in Figure 1, the notebook computer AC adapter that this is routine is made of switching power circuit, diverter switch, dc output end mouth, charging control circuit and battery interface.AC-input voltage is converted to suitable direct voltage through switching power circuit, select through diverter switch, providing operating voltage by the dc output end mouth for notebook computer on the one hand, is the reserve battery charging by charging control circuit and battery interface on the other hand.If select the enough switching power circuits of capacity for use, also can be without diverter switch, and directly output DC is divided into two-way, can when using notebook computer to carry out work, be the reserve battery charging.Switching power circuit shown in Figure 1, be the switching power circuit of a typical pulse width modulation voltage stabilizing, its structure comprises ac-dc converter circuit (AC/DC circuit), pulse width modulation circuit (pwm circuit), pulse transformer, drive circuit, current rectifying and wave filtering circuit and voltage stabilizing circuit.Charging control circuit can be made of the power management integrated circuit chip, as TWL2203 integrated circuit of TEXAC INSTRUMTS INC. etc.; Also can select DC/DC (DC/DC conversion) device formation cheaply for use, as the AMC34063 of ADD MICROTECH CORP. production.These circuit all have matured product available, no longer describe in detail herein.
