Specific implementation mode
The embodiments of the present invention are described in detail below in conjunction with attached drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
The one side of the utility model, provide one kind can charging/discharging type flashlight, including accumulator 1, microUSB
Interface 2, LED light emitting sources 3, controller, charging circuit, discharge circuit and switch 4, the microUSB interfaces 2 are filled by described
Circuit is connect with the charging end of the accumulator 1, the output end of the accumulator 1 by the discharge circuit with it is described
MicroUSB interfaces 2 connect, and the accumulator 1 is powered to the controller, the controller and the microUSB interfaces 2
ID pins connect, and the controller controls the discharge circuit to the microUSB interfaces 2 according to the level of the ID pins
Electric discharge, the controller connect power supply of the accumulator 1 to the LED light emitting sources 3 when the switch 4 is pressed.
In OTG, Initial master equipment is known as A equipment, and peripheral hardware is known as B device.That is, mobile phone can both have been done outside
And if data can be transmitted with hosted, it can determine that initial roles (are determined by the state of ID lines with the connection type of cable
It is fixed).There are 5 lines in USB OTG interfaces：2 be used for transmit data (D+, D-), 1 be power cord (VBUS), 1 then be ground connection
Line (GND), 1 be ID lines.Wherein, ID lines are for identifying different cable endpoint, the ID in mini-A plugs (i.e. A peripheral hardwares)
Pin is grounded, the ID pin floatings in mini-B plugs (i.e. B peripheral hardwares).When OTG equipment detects the ID pins of ground connection, indicate
Acquiescence is A equipment (host), and the equipment for detecting ID pin floatings is then considered B device (peripheral hardware).Therefore, ID can be passed through
The level of pin come judge charge or discharge.
Referring to FIG. 2, when charging, external charger is connected by the microUSB interfaces 2 of standard charging line and flashlight,
