Abstract

The invention discloses a multifunctional notebook power adapter which consists of a plug (1), a transformer (2), a rectifier (3), a lithium battery management panel (4), a lithium battery (5), a voltage stabilizing circuit board (6), an output interface (7), a two-hole socket (8), a heat dissipation sheet (9), a shell (10) and a notebook power joint (11). The multifunctional notebook power adapter has the function of a common notebook power adapter, and the lithium battery is additionally arranged, so that the battery cruising power of electronic equipment is improved; meanwhile, various power output interfaces including the socket and a USB guarantee the power supply demands of different sets of electricity utilization equipment; therefore, in a traveling process, people do not need to carry a notebook computer adapter, a mobile phone charger and the like any more, and only need to take one adapter for use. On the basis of the common power adapter, the various interfaces are added so as to adapt to different electronic products, and traveling is greatly facilitated; meanwhile, by the arrangement of the large-sized heat dissipation sheet, heat dissipation of a power supply is guaranteed, and the power supply is safer to use.

Description

A kind of multifunctional note power supply adaptor

Background technology
Along with the development of science and technology, each class of electronic devices has become product indispensable in people's daily life, the products such as such as mobile phone, panel computer, notebook computer are also towards more high-end, more intelligent, more practical future development, especially the popularization of large-screen mobile phone and panel computer, make this electronic product in the face of a fatal problem, that is exactly power consumption.And for the equipment such as notebook computer, mobile phone, be again that people go on a journey the equipment often needing to portably use, especially for businessperson, notebook computer and mobile phone are the requisite equipment of trip.
Battery due to portable mobile termianl is subject to the impact of volume, fail safe each side, and capacity is generally not too large, and this is extremely important for trip personage with regard to making charging device.Often kind of electronic equipment is provided with corresponding charging device now, causes people to have to carry various charging device in the process of trip, very loaded down with trivial details.
For this situation, we devise a kind of multifunctional note power supply adaptor, this multifunctional note power supply adaptor not only possesses the function of conventional laptop adapter, also there is multiple output interface, comprise 220V AC socket, laptop delivery outlet, USB delivery outlet, the charge requirement of the various equipment of user can be met; Simultaneously, adapter itself is also built-in lithium battery, by switch open or closedown lithium battery, thus the discharge and recharge of lithium battery can be controlled, make power supply adaptor possess the function of portable power source, and large fin is installed in the inside of laptop adapter, improve the heat dispersion of adapter, adapter is used safer.
Summary of the invention
The object of the invention is to design a kind of multifunctional note power supply adaptor, under the prerequisite can powered to notebook computer, the electronic equipment chargings such as mobile phone, panel computer, MP3 can be given, simultaneously, built-in lithium battery can also make adapter use not having the region of civil power, complete the function that portable power source possesses, the trip life be convenient for people to.
Technical scheme of the present invention is: a kind of multifunctional note power supply adaptor, is made up of plug, transformer, rectifier, lithium battery management board, lithium battery, voltage stabilizing circuit plate, output interface, two spring hole scokets, fin, shell and laptop joint; Wherein, transformer inputs is connected with plug, and output is connected with rectifier; Rectifier outputs to lithium battery management board and voltage stabilizing circuit plate; Lithium battery is connected with lithium battery management board; Output interface is all connected with voltage stabilizing circuit plate with laptop joint; Fin is arranged on the bottom of shell.
Above-mentioned output interface is the USB interface of 5V.
Above-mentioned lithium battery management board, lithium battery and voltage stabilizing circuit plate are all screwed on fin, and, contact-making surface adds heat conductive silica gel and ensure that contact is good.
Above-mentioned lithium battery management board there is switch, needs, to during lithium cell charging or when needing to use lithium battery power supply, to open switch, closing switch when not using, can avoid carrying out discharge and recharge to lithium battery frequently, affect the life-span of lithium battery.
Above-mentioned lithium battery management board has two indicator lights, during switch connection, indicator light is bright; When giving lithium cell charging, when red, when lithium battery supplying power for outside, green light.
Operation principle of the present invention is: inserted by plug in commercial power socket, and laptop joint inserts in notebook computer, and can realize the basic function of a kind of multifunctional note power supply adaptor of the present invention, namely notebook computer is powered; Now, if need external speaker or wiring board will be expanded, attaching plug is inserted laptop adapter two spring hole scoket; If need to charge the phone, data wire one end of mobile phone is inserted into output interface (USB), the other end connects mobile phone; If when not having civil power, use portable power source function, opening the switch on lithium battery management board, connect power supply unit, when lithium battery is outwards powered, the green indicating lamp on lithium battery management board is bright; If need, to lithium cell charging, to connect civil power, open the switch on lithium battery management board, during when red on lithium battery management board, represent to lithium cell charging.
