Background Art

Existing notebook computer generally has not more than four USB interface, and many of the electronic equipment on the market are with the computer through the USB interface is connected, is connected with a plurality of electronic devices at the same time is a part of the an. Existing electronic equipment often a device would need to occupy a USB interface, this has resulted in the USB interface of the deficiency of the resources. As the various needs of the notebook computer through the USB interface is connected with the popularization of electronic equipment, one can simultaneously support multiple devices at the same time communication of USB transceiver of the wireless signal of the notebook computer becomes a natural demand. However, not relevant in the prior art described.

Content of the invention

The purpose of this invention is to offer a kind of external, on the basis of the USB interface, can be supported at the same time the wireless mouse, wireless keyboard, wireless network connection external multifunctional notebook computer USB wireless signal transceiver.

To achieve the purpose of this invention the technical solutions for the: external multifunctional notebook computer USB wireless signal transceiver, including USB interface component, engineering plastic casing, wireless mouse signal receiving module, the wireless keyboard signal receiving module, the wireless network adaptation module and USB   chip   HUB, the wireless mouse signal receiving module, the wireless keyboard signal receiving module and a wireless network adaptation module through the USB   chip   HUB is connected with the USB interface component, wherein the wireless mouse signal receiving module, the wireless keyboard signal receiving module, the wireless network adaptation module and USB   HUB   chip are located on the engineering plastic casing internal, USB interface engineering plastics member is located external of the shell.

The wireless mouse signal receiving module is a LT8900RF types of chip.

The wireless keyboard signal receiving module is a nRF24E1 types of chip.

Wireless network adaptation module is a Ralink3070 models to chip.

 The model number of the chip is   HUB USB NEC720114.

Compared with the prior art, the present invention, the obvious advantages that: 1) the structure is compact, in the invention, the four kinds of signals in the transceiver module integration a; 2) reduces the occupation of USB interface; 3) easy carrying and installation; 4) low cost saving raw materials.

Mode of execution

Combined with photos, a of this invention external multifunctional notebook computer USB wireless signal transceiver, including USB interface component 1, engineering plastic casing 2, a wireless mouse signal receiving module 3, wireless keyboard signal receiving module 4, wireless network adaptation module 5 and USB   HUB   chip 6, the wireless mouse signal receiving module 3, wireless keyboard signal receiving module 4 and wireless network adaptation module 5 through the USB   chip   HUB 6 with the USB interface component 1 is connected, wherein the wireless mouse signal receiving module 3, wireless keyboard signal receiving module 4, wireless network adaptation module 5 and USB   HUB   chip 6 are located on the engineering plastic casing 2 internal, USB interface component 1 located in engineering plastic casing 2 of the external.

The wireless mouse signal receiving module 3 for LT8900RF types of chip.

The wireless keyboard signal receiving module 4 for nRF24E1 types of chip.

Wireless network adaptation module 5 for Ralink3070 types of chip.

USB   HUB   chip 6 of the type of NEC720114.

The functions of each module of the present invention are as follows: the wireless mouse signal receiving module is used for receiving the wireless mouse and the signal transmitted is transmitted to the computer; a wireless keyboard signal receiving module is used for receiving wireless keyboard and the signal transmitted is transmitted to the computer; the wireless network adaptation module is used for realizing the computer and radio wifi network communication signal conversion.

The principle of this invention is to: existing various electronic devices to use when communicating with wireless signal receiving module has been proven in practice is available, and having a bus arbitration mechanism is, therefore, different module occupying different USB interface is clearly not necessary. Therefore, we will be several kinds of communication module together, occupied with a USB interface, this is technically feasible.

In conjuction with the following, detailed descriptions of embodiments of the present invention.

Combined with Figure 1, the appearance of this invention is shown in the Figure three views, mainly as a USB interface component 1, a engineering plastic casing 2.

Combining Figure 2, the internal structure of the present invention is shown in the Figure, 3 for the wireless mouse signal receiving module, 4 is a wireless keyboard signal receiving module, 5 is a wireless network adapter module. Wherein 3, 4 two parts the principle of CDMA-based,   5 based on IEEE 802.11 g standard, 6 by a common USB   HUB chip, such as chip NEC720114. The different signal receiving module are respectively realized with different mutual identification of the signal source with the communication.

Wireless mouse signal receiving module 3, wireless keyboard signal receiving module 4, the wireless network adaptation module 5 are respectively connected with the common USB   HUB chip 6 is connected with the corresponding pin. The USB chip   HUB of 6 with relative pins of USB interface component 1 is connected. Finally the above structure is encapsulated into the engineering plastic casing 2 in. When in use, the USB interface component 1 is inserted into the USB interface of the computer of the equipment to the success of the mount to a universal Serial bus.

The device of this invention has the advantages of compact structure, the four kinds of signals in the transceiver module to a integration, easy carrying and installation.
