Abstract
The utility model discloses a 5V-output USB (universal serial bus) charge device for a motorcycle. The 5V-output USB charge device comprises a shell provided with a USB interface and used for installing a charge circuit, and the charge circuit installed in the shell, wherein one end of the charge circuit is connected with an external power supply, and the other end of the charge circuit is connected with the USB interface. The 5V-output USB charge device has the following advantages that 1, a voltage output device supplies power for a mobile phone via the USB interface, thus having high-speed, safe and practical effects; 2, a voltage-regulator tube can convert an input voltage to a voltage output used for charging the mobile phone; and 3, a ceramic capacitor and an electrolytic capacitor can be used for filtering and supplying a stable output.
Description
Technical field
The utility model relates to a kind of mobile charging device, and especially a kind of motorcycle is used the 5V charging device.
Background technology
People run into mobile phone through regular meeting on the road and cause the problem of shutting down because of electric weight is not enough, cause the inconvenience in the use to the user.
The described motorcycle charger that is used for cell-phone charging of conventional device such as CN200910184121.5 patent; Comprise storage battery; Also comprise box, charger circuit board; The top of said box is provided with cover plate, in box, is provided with charger circuit board, on the shell of box, is provided with charging inlet; Said charger circuit board is connected with charging inlet with storage battery respectively; Also be provided with the fixed installation hole on the shell of said box, box is fixed on the motorcycle through the fixed installation hole.
[0004]But the weak point of above-mentioned patent is that the voltage output stability is bad, and the charging interval is long, be unfavorable for using, and do not provide relevant charging circuit in its content, and there is poor signal in existing charging circuit, the shortcoming that stability is not enough.
Summary of the invention
The utility model technical problem to be solved provides a kind of mobile phone easy to use and fast and stable and uses portable charging device.
A kind of motorcycle USB5V output charging device comprises a housing, is provided with a USB interface, and is used to install charging circuit; One charging circuit is installed in the housing, one of which termination external power supply, another termination USB interface.
The shell of said box is provided with waterproof cover, and is pressed on the USB port; Also be provided with an installing hole on the housing, housing is installed in motorcycle last through installing hole; Described external power supply is a motorcycle 12V power supply.
Described circuit comprises an external power supply input, the voltage-stabiliser tube of connecting between the output, input and output, and diode is serially connected between input and the voltage-stabiliser tube; Ceramic disc capacitor, electrochemical capacitor are serially connected between voltage-stabiliser tube and the diode respectively and between voltage-stabiliser tube and the output.Said housing is made up of first housing and second housing.
The said motorcycle USB5V output of the utility model charging device, its advantage is following:
1. said voltage output device is the mobile phone power supply through USB interface, and it is fast to have speed, safe and practical effect;
2. voltage-stabiliser tube can convert input voltage into supply cell-phone charging to use voltage output;
3. ceramic disc capacitor and electrochemical capacitor can be used for filtering and supply stable output, to reduce its output time and easy to use.
