Abstract
The utility model discloses a television USB interface power supply switch, which is provided with a high level and low level switching module, and the switching module can selectively control the on-state/off-state of the power supply of an USB interface according to control instructions when a television is in non-USB channel operation. Compared with the prior art, the utility model can supply electric power to the USB interface when the television selects the non-USB channels, so the USB interface can supply electricity for other electronic equipment (supporting USB power supply), and the flexibility of the equipment is improved.
Description
Technical field
The utility model relates to television set, relates in particular to a kind of television set USB interface power switch.
Background technology
Present many television sets have USB interface, and when television set was selected non-USB passage, such as TV, AV etc., television set to the USB interface power supply, can't not discerned even if connect USB device this moment yet.But if the user when using non-USB passage (such as seeing TV), wants to use USB interface to give electronic equipment (supporting the USB power supply) power supply again, so existing television set just can not be accomplished, thereby make troubles to the user.
The utility model content
The utility model is will solve existing television set when selecting non-USB passage for use, can't give the problem of other electronic equipment (supporting the USB power supply) power supply by USB interface, propose a kind of television set USB interface power switch.
For solving the problems of the technologies described above, the technical scheme that the utility model proposes is: design a kind of television set USB interface power switch, its USB interface power switch is provided with high level and low level handover module, when this handover module is in the operation of non-USB passage at television set, can select the ON/OFF of control USB interface power supply according to control command.
Described control command can be imported with remote controller key or TV menu.
Compared with prior art, the utility model can to the USB interface power supply, make this USB interface can give other electronic equipment (supporting the USB power supply) power supply when television set is selected non-USB passage for use, increases the flexibility of equipment.
Description of drawings
Below in conjunction with drawings and Examples the utility model is made detailed explanation, wherein:
Fig. 1 is the theory diagram of the utility model preferred embodiment;
Fig. 2 is the flow chart of the utility model preferred embodiment.
Embodiment
The utility model discloses a kind of television set USB interface power switch, its USB interface power switch is provided with high level and low level handover module, when this handover module is in the operation of non-USB passage at television set, can select the ON/OFF of control USB interface power supply according to control command.Referring to shown in Fig. 1, the theory diagram of the utility model preferred embodiment.
In preferred embodiment, described control command can be imported with remote controller key or TV menu.
Fig. 2 shows the flow process of the utility model preferred embodiment.During use, at first access USB power supply choice menus by remote controller switching shortcut or TV menu; Regulate USB power supply option state as required; Central control module sends switch controlling signal according to the power supply option state of determining; The switch module suspension control signal drives, and when USB power supply option is made as out, the IO mouth that is used to control the USB power supply is arranged to high level (being generally 5V), makes USB interface have 5V voltage to supply with.At this moment, no matter the user uses TV at which kind of passage, can use USB interface to powering such as small electric apparatus such as mobile phone, electric fan, desk lamp (supporting the USB power supply).When USB power supply option is made as the pass, the IO mouth that is used to control the USB power supply is arranged to low level (being generally 0V), make USB interface not have electric energy output, the user just cannot use the USB power supply unit at non-USB passage like this.
Above embodiment is only for illustrating non-providing constraints.Anyly do not break away from spirit of the present invention and category, and, all should be contained among the claim scope of the application of enclosing its equivalent modifications of carrying out or change.
Claims (2)
1. television set USB interface power switch, it is characterized in that: described USB interface power switch is provided with high level and low level handover module, when this handover module is in the operation of non-USB passage at television set, can select the ON/OFF of control USB interface power supply according to control command.
2. power control switch as claimed in claim 1 is characterized in that: described control command is imported with remote controller key or TV menu.
