Description

A kind of multifunctional charger

Technical field

The utility model relates to a kind of onboard charger, is a kind of multifunctional charger.

Background technology

modern society, automobile has become a kind of general vehicles, for the people who drives out tourism or go on business, often can meet GPS, the situation that the electronic product such as mobile phone and MP3 need to charge, if can't find charge power supply when driving is these electronic product chargings, necessity has influence on work or the mood of going on a tour, and for this situation, released in the market onboard charger, utilize the cigar lighter power supply on car to charge in the process of driving, then for present onboard charger, function is mostly all more single, only be used for charging, add some functional not strong attach features, cause the charger volume larger, cost is higher, all be difficult for promoting.

Summary of the invention

The purpose of this utility model is for the existing state of the art, and a kind of multi-functional onboard charger is provided, and except satisfying basic charge function, also has the function of LED torch function and outside vehicle-mounted other electric equipments.

For achieving the above object, the utility model adopts following technical scheme:

The utility model is a kind of multifunctional charger, comprise that shell, LED lamp, conversion socket, power module of voltage regulation, battery management module, CPU integrated circuit, field effect transistor, internal battery, USB interface, point touch switch and accessory circuit, by cigar lighter power supply output 12-24V direct voltage, one route parallel circuits forms several conversion sockets, one the tunnel connects battery management module through power module of voltage regulation, one the tunnel connects CPU integrated circuit and USB interface through power module of voltage regulation, and the LED lamp is connected with integrated circuit by field effect transistor.

Described field effect transistor has three electrodes, is respectively source electrode, grid, drain electrode, and source electrode connects the LED lamp, and grid is connected with integrated circuit, and drain electrode arrives ground through constant current resistance R4.

The quantity of described conversion socket is at least 1.

Has magnet on described shell.

The utility model has the advantage of: utilize the output of automobile cigarette lighter power supply, a route parallel circuits forms several conversion sockets, can outside vehicle-mounted other electric equipments.

One the tunnel connects CPU integrated circuit and USB interface through power module of voltage regulation, except passing through the USB interface charge function, can also control the CPU integrated circuit by the tactile switch of point, make its output PWM and pulse signal control field effect transistor and make the LED lamp produce the low light level, high light or quick-fried sudden strain of a muscle.

One the tunnel is the internal battery charging through power module of voltage regulation connection battery management module; internal battery can continue charge and store when driving; when stopping; the cigar lighter power supply stops output, and this internal battery will through the battery management module discharge, be integrated circuit and USB interface power supply so; battery management module can be cut off power supply when discharging into certain low-voltage; play the effect of protection battery, certainly, this internal battery also can utilize external connection battery to replace.

This utility model continues charging for electronic product except providing effectively, the function that also has LED torch function and outside vehicle-mounted other electric equipments, and its shell is with strong magnets, can be adsorbed on vehicle body or on roof, utilize the quick-fried sudden strain of a muscle of LED lamp to play warning function when vehicle trouble, ensure inherently safe, its simple structure, cost is lower, is easy to promote.

Description of drawings:

Accompanying drawing 1 is line map within utility model.

Embodiment:

Understand for the juror can be had purpose, feature and the function of the utility model further, hereby lift preferred embodiment and coordinate graphic being described in detail as follows:

See also shown in Figure 1, be the internal wiring figure of the preferred embodiment of the utility model, the utility model is a kind of multifunctional charger, comprises that shell, LED lamp, conversion socket, power module of voltage regulation 1, battery management module 2, CPU integrated circuit (IC) 1, field effect transistor Q1, internal battery B1, USB interface P1, point touch switch S 1 and accessory circuit.Utilize the output of automobile cigarette lighter power supply, a route parallel circuits forms one or more conversion sockets 3, can utilize the outside vehicle-mounted more electric equipment of these conversion sockets 3.

One the tunnel through connecting CPU integrated circuit (IC) 1 and USB interface P1 after power module of voltage regulation 1 adjustment electric current and voltage, except passing through USB interface P1 charge function, can also be by tactile switch S 1 a control integration IC circuit 1, this point touches switch S 1 and touches to integrated circuit (IC) 1 signal by point, making its output PWM and pulse signal control field effect transistor Q1 makes LED lamp D1 produce the low light level, high light or quick-fried sudden strain of a muscle, point touches and is long bright high light, touch for the second time and be the long bright low light level, touching for the third time is quick-fried sudden strain of a muscle, certainly, this point touches switch S 1 and can utilize the touch-screen switch replacement.
