Abstract
The utility model belongs to a USB deconcentrator and relates to a wireless USB deconcentrator. The wireless USB deconcentrator comprises a USB deconcentrator main body. The USB deconcentrator main body is characterized in that: the wireless USB deconcentrator further comprises a signal emission portion, a signal reception portion and a cell power supply device for supplying power to the signal emission portion; the signal emission portion is connected to the USB deconcentrator main body; the signal reception portion is connected with a host; and the signal emission portion and the signal reception portion are in wireless connection. The problem that in the prior art, transmission rate is influenced due to an over-long transmission line of a USB deconcentrator or usage space of host ports is influenced because the ports are too close is solved; and thus the USB deconcentrator can be placed anywhere in space without the limitation of the position of the host.
Description
Technical field
The utility model belongs to USB deconcentrator, is specifically related to a kind of Wireless USB deconcentrator.
Background technology
The external equipment product of computer is more and more now, such as sound equipment, video, earphone, printer, mouse, keyboard etc., nearly all use USB interface, yet computer does not have so much interface, the function of USB deconcentrator is to allow computer have more USB interface to use, USB deconcentrator itself has the data wire of a USB interface to connect on computers, thereby the voltage on computer is diverted to the socket of USB deconcentrator, just can allow USB deconcentrator connect digital equipment, for uploading on computers downloaded data simultaneously.The USB deconcentrator without external power supply of existing majority, may be due to the transmission line of USB deconcentrator the oversize speed that affects transfer of data, some products are done transmission line shortlyer solves this problem, but can make USB divide port and up USB port too to approach and take the usage space of other USB port of main frame.
Summary of the invention
The purpose of this utility model is to overcome USB deconcentrator in prior art because transmission line is long, to affect the too approaching problem that affects host port usage space of transmission rate or port.
For this reason, the utility model provides a kind of Wireless USB deconcentrator, comprise USB deconcentrator main body, it is characterized in that: also comprise signal emission part and signal receive section and the battery powdered device to signal emission part power supply, signal emission part is connected in USB deconcentrator main body, signal receive section is connected with main frame, signal emission part and signal receive section wireless connections.
Described signal emission part comprises radio frequency communication devices and transmitting antenna, and radio frequency communication devices is connected in described USB deconcentrator main body, and transmitting antenna is connected on radio frequency communication devices.
Described signal emission part is connected by infrared radio with signal receive section.
Described signal emission part is connected by blue teeth wireless with signal receive section.
Described signal receive section comprises reception antenna, amplification and rectification circuit and single-chip microcomputer, and wherein single-chip microcomputer connects described main frame, and reception antenna is positioned at outermost end, and reception antenna is connected with single-chip microcomputer by amplification and rectification circuit.
The wireless receiving emitter that the utility model adopts, avoided USB deconcentrator in prior art because transmission line is long, to affect the too approaching problem that affects host port usage space of transmission rate or port, USB deconcentrator spatially can be positioned over Anywhere, not be subject to the restriction of position of host machine.
Below with reference to accompanying drawing, the utility model is described in further details.
Accompanying drawing explanation
