DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

As shown in FIGS. 2 and 3, a preferred embodiment of a USB HUB with a TV receiver 2(3) in the present invention includes a case 10, a PC board 20, a TV module 30, a USB control unit 40, a connecting unit 50, a panel controlling unit 60 and a power circuit 70.

The case 10 is provided with plural openings 11 bored at preset locations and an accommodating chamber 12 inside it.

The PC board 20 is installed in the accommodating chamber 12 of the case 10.

The TV module 30 fixed properly on the PC board 20 is provided with an antenna unit 31, a tuning unit 32 connected with the antenna unit 31 to receive wireless signals, a digital image processing unit 33 connected with one end of the tuning unit 32, an auxiliary antenna socket 34 connected with the antenna unit 31 for being plugged by an external antenna 311, a remote-controlled unit 35 connected with the digital image processing unit 33, and an audio output socket 36 fixed in one of the openings 11 for connecting with the digital image processing unit 33. The antenna unit 31 is a printed circuit antenna of copper foil printed on the PC board 20, and can also be a micro antenna fixed on the PC board 20. The remote-controlled unit 35 is composed of a remote-controlled signal emitter 351, a remote-controlled signal receiver 352 and a control loop 353. The control loop 353, an infrared control loop set properly on the PC board 20, is connected with the digital image processing unit 33 by its one end and the remote-controlled signal receiver 352 by the other end. The remote-controlled signal receiver 352 fixed in one of the openings 11 is connected with the control loop 353.

The USB controlling unit 40 fixed properly on the PC board 20 is provided with a USB HUB control IC 41 and a USB control interface 42 that is connected with the digital image processing unit 33 of the TV module 30 by its one end and the USB HUB control IC 41 by the other end.

The connecting unit 50 provided with plural USB connecting devices 51 is fixed on the PC board 20 to connect with the USB HUB control IC 41 of the USB controlling unit 40 by its one side and fixed in some of the openings 11 of the case 10 by another side for connecting with other peripherals. One of the USB connecting devices 51 is an USB male plug 511 for connecting with an electronic appliance and the rest are female sockets 512 used as USB interfacial sockets.

The panel controlling unit 60 is provided with a panel processor 61 fixed properly on the PC board 20 to connect with the digital image processing unit 33 of the TV module 30, and plural control switches 62 fixed in one of the openings 11 and connected with the panel processor 62.

The power loop 70 is fixed properly on the PC board 20 to connect with the TV module 30 for supplying various voltage modes for the invention, and connected with an external power socket 71.

In using, as shown in FIGS. 23, when TV signal is hoped to be received, a user has to select TV channel and preset functions wanted via turning on the control switches 62, so that the remote-controlled signal emitter 351 is to send a control signal to the remote-controlled signal receiver 352 for transmitting to the control loop 353 to control the TV module 30 to receive the desired TV channel and preset functions. The TV module 30 receives wireless signal by means of the antenna unit 31 that can be intensified by plugging the external antenna 311 in the auxiliary antenna socket 34 to receive signal intensively if receiving badly. Then, the TV module 30 is to alter the wireless signal into TV signal that is to be transmitted by the USB controlling unit 40, and next, to the electronic device connected with the USB male plug 511 of the connecting unit 50 for showing TV program. If power is insufficient to meet several connections of the USB interfaces, the external power socket 71 of the power loop 70 can be connected with an external power 72 to supply power needed.

As shown in FIG. 5, a second preferred embodiment of USB HUB with a TV receiver in the present invention has the same parts as the first one does except that the USB male plug 511 is connected with an additional extended line 513 to connect with an electronic appliance.

The invention has the following advantages as can be seen from the foresaid description.

1. The invention contains the TV module provided with an antenna unit having a printed circuit antenna on the PC board that is able to receive TV signal intensively by connecting the external antenna in the auxiliary antenna socket.

2. The invention can not only increase USB interfacial sockets, but also receive a TV signal, achieving a purpose of miniaturization for saving space.

While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
