Description
Technical field
Charging of mobile devices field, more particularly to mobile device intelligence charging equipment field are the utility model is related to, specifically
Refer to a kind of multi-functional charging cabinet.
Background technology
Smart mobile phone, PAD etc. are developed into today, be not merely you I he use instrument, being even more can not during we live
An or scarce part.Say that the most used thing is mobile phone certainly, on road either on and off duty, or during rest
Between, mobile phone is always with left and right.We are also seen a film using PAD, and browse network, takes pictures.So frequently use mobile phone
With PAD, also have led to frequent charging the phone in our daily lifes.Read at the same time now with many hotels or electronics
Look at room, meeting room etc., be all to use PAD, then need also just to need more sockets to these PAD chargings at the same time.If
Multi-functional charging cabinet, then can easily realize while charge to 1-64 PAD or mobile phone.
Utility model content
The purpose of the utility model is to overcome it is above-mentioned in the prior art the shortcomings that, there is provided one kind can be at the same time to multiple
PAD or the multi-functional charging cabinet of mobile phone charging.
In order to realize above-mentioned purpose, the multi-functional charging cabinet of the utility model is specific as follows：
The multi-functional charging cabinet, including USB interface, it is mainly characterized by, and the USB interface passes through type matching chip
It is connected to the power unit.
It is preferred that the type matching chip is GL888F chips.
More preferably, the P5V pins connection of the GL888F chips power module, the GL888F chips
D- pins and D+ pins are connected respectively to the D- pins of the USB interface and D+ pins.
It is preferred that the number of the USB interface is multiple, the number of the type matching chip and the USB
The number of interface is consistent, and the type matching chip connects one to one with the USB interface.
More preferably, the number of the USB interface is 64, and the number of the type matching chip is also 64.
It is preferred that the power unit includes a commercial power interface and an AC/DC modular converters, the commercial power interface are led to
Cross AC/DC modular converters and be connected to the type matching chip.
It is preferred that the USB interface and type matching chip is arranged on a pcb board, and pass through the pcb board
Realize the connection relation of the USB interface and type matching chip.
Using the multi-functional charging cabinet, since it is with multiple USB interfaces, and it is connected to by type matching chip described
Power module, therefore after USB interface accesses external charging equipment, the type matching chip can treat described
The type of charging equipment is matched, to D- the and D+ pins of USB interface to match the voltage of charging equipment type and connection
Relation, can realize the charging of 1 to 64 different types of charging equipment at the same time, very simple is convenient, can apply and scheme
Book shop, classroom, Digital Reading Room, station etc., supply student or passenger's charging.Dining room is can be used at the same time, is made for client
Ordered dishes with PAD.
