Background

With the development and popularization of computers, the demands of users are becoming diversified, and in order to improve the expandability of computers, more and more external devices are developed, and while these peripheral devices are widely used, how to effectively and conveniently connect these devices with computers is a big problem.

Intel and microsoft started to promote a Universal Serial Bus (USB), which is a Serial Bus standard for connecting a computer system and external devices, and is also a technical specification of an input/output interface, in order to unify the connection manner of peripherals and computers, and nowadays, the USB interface is widely applied to a large number of external devices.

However, due to the popularization of the USB interface, most external devices require the USB interface, and the USB slots that can be provided by the computer are very limited, and particularly, in consideration of the characteristics of lightness and thinness, the size of the notebook computer or all-in-one machine is reduced to the maximum extent, and only two or three USB slots are provided, which obviously cannot meet the needs of most users.

Due to the popularization of computers, most users may own a plurality of devices at present, which is particularly obvious in the environments of laboratories, machine rooms and the like. USB hubs currently on the market only support the simultaneous connection of peripherals to one device. If people need to switch and use among the plurality of devices frequently, two schemes can be met at present, the first scheme needs to plug and pull the USB hubs among the plurality of devices frequently, the second scheme is to purchase a plurality of USB hubs and a plurality of sets of peripherals, the former scheme is very troublesome, meanwhile, the frequent plugging and pulling also risks damaging the peripherals, and the latter scheme seriously increases the cost.

In addition, most USB hubs and devices in the market are connected by common physical plugging, and USB slots of many computers are designed in positions which are not convenient to touch frequently due to aesthetic reasons, for example, a desktop case is designed with USB slots on the rear side, and an all-in-one machine places USB at the rear end of a screen, which brings difficulties for users to insert or remove the USB hubs.

In summary, a novel bluetooth-controlled multi-device switching hub is provided in the market, which not only can meet the requirement of users for using diversified peripherals, but also can be switched between multiple devices without purchasing multiple hubs and multiple sets of devices.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a main aim at provides a many equipment switch USB concentrator based on bluetooth control, permeable bluetooth control switch unit open and close, and then freely switch between a plurality of equipment, solved in the background each item problem.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a multi-device switching USB hub based on Bluetooth control comprises a plurality of input ports, a plurality of output ports and a controller, wherein each input/output port comprises a switch unit, a USB input/output port and a light emitting diode, the light emitting diodes are respectively connected with a power supply and the switch unit to display whether the ports are conducted or not, and the light emitting diodes emit light when the ports are conducted.

The controller has set up power module, bluetooth control module and relay switch module, and bluetooth module links to each other with power module, relay switch module respectively, and wherein the switch unit contains in relay switch module.

Furthermore, the controller is in communication connection with equipment such as a computer or a mobile phone through the Bluetooth module, the equipment such as the computer or the mobile phone receives a control instruction, the Bluetooth module outputs high and low levels to control the attraction and release of a certain specific switch contact of the relay switch module through the processing of the Bluetooth module, the connection and disconnection of a specified circuit are realized, and meanwhile, the Bluetooth module can feed back processing result information to the equipment such as the computer or the mobile phone to display the on-off state.

The utility model has the advantages that: except for normal uninstallation of the USB hub and the connected peripheral equipment from the computer operating system or physical unplugging, the switch unit can be controlled through Bluetooth, and then a data path between the USB hub and the computer is cut off or established. And moreover, a plurality of computers can be connected simultaneously, and a USB concentrator is not required to be plugged and unplugged physically, so that a set of peripheral equipment can be switched and used among the computers very conveniently.
