Description

Keyboard system with automatic identification electrical parameter

Technical field

The utility model relates to a kind of keyboard system, in particular to a kind of keyboard system with automatic identification electrical parameter.

Background technique

Keyboard is a kind of instruction and data input unit for operating equipment operation.The type of keyboard is a variety of more at present Sample, backlight keyboard originates from common keyboard, at home under the drive of Game Market, in order to meet more higher player's demands, Keyboard developer just begins one's study multi-functional keyboard, wherein just there is backlight keyboard.Backlight keyboard is mainly reflected in keyboard Or panel shines, and key letter can be also clearly seen that in the case where not turning on light at night.Keyboard is connect using USB mostly Head, and connected by the USB interface of USB joint and host, and current host often provides USB 2.0 and 3.0 liang of USB Kind interface.According to relevant consensus standard, the supply voltage of USB 3.0 is direct current 5.0V ± 5%, the power supply with standard USB 2.0 Voltage is identical.The difference is that standard regulation 3.0 maximum output current of USB is not less than 0.9A, and the maximum output of USB 2.0 Electric current maximum 0.5A, USB 3.0 can export bigger power in contrast.If backlight keyboard is set as maximum defeated when leaving the factory Enter the current standard that electric current is not less than 0.9A USB 3.0, host can be burnt out when then being connected with 2.0 host interface of USB；If back Light keyboard is set as the current standard of maximum input current 0.5A USB 2.0 when leaving the factory, then with 3.0 host interface of USB When being connected, and the advantage of keyboard cannot be played.

Utility model content

Technical problem to be solved in the utility model is to have overcome the deficiencies of the prior art and provide a kind of energy effective protection Host can play the keyboard system with automatic identification electrical parameter of USB interface sharpest edges again.

The technical scheme adopted by the utility model is the utility model includes processor, key module, the luminous mould of LED Block and USB interface, the keyboard system with automatic identification electrical parameter further includes switching module, the key module, LED hair Optical module, the switching module are electrically connected with the processor, the power supply line of the USB interface and switching module electricity Property connection, the LED light module and the switching module be electrically connected, the power line data line of the USB interface with it is described Processor is electrically connected；When work, the electrical parameter that the processor accesses the USB interface is identified, the subsequent place It manages device and controls the switching module and by LED light module described in corresponding plant-grid connection.

Further, the switching module includes switching switch, the first power supply circuit and the second power supply circuit, and described first supplies Circuit and second power supply circuit are in parallel and switch and be electrically connected with the switching, the power supply line of the USB interface and The switching switch electrical connection, the switching switch are connect with the processor signal.

Further, the keyboard system with automatic identification electrical parameter further includes the finger being electrically connected with the processor Show lamp.

Further, the maximum current that first power supply circuit provides is 0.5A.

Further, the electric current that second power supply circuit provides is not less than 0.9A.

The beneficial effects of the utility model are: since the utility model uses the design of automatic identification electrical parameter, including place Device, key module, LED light module and USB interface are managed, the keyboard system with automatic identification electrical parameter further includes switching Module, the key module, LED light module, the switching module are electrically connected with the processor, the USB interface Power supply line and the switching module be electrically connected, the LED light module and the switching module are electrically connected, the USB The power line data line and the processor of interface are electrically connected；When work, electricity that the processor accesses the USB interface Parameter is identified that then the processor controls the switching module for LED light module described in corresponding plant-grid connection, institute With, the fine protected host of the utility model energy, and USB interface sharpest edges can be played.

Detailed description of the invention

Fig. 1 is the principles of the present invention structure chart.

Specific embodiment

As shown in Figure 1, in the present embodiment, the utility model includes processor 1, key module 2,3 and of LED light module USB interface 4, it is characterised in that: the keyboard system with automatic identification electrical parameter further includes switching module 5, the key Module 2, LED light module 3, the switching module 5 are electrically connected with the processor 1, the power supply line of the USB interface 4 It is electrically connected with the switching module 5, the LED light module 3 is electrically connected with the switching module 5, the USB interface 4 Power line data line and the processor 1 be electrically connected；When work, electricity that the processor 1 accesses the USB interface 4 Parameter identified, the subsequent processor 1 controls the switching module 5 and LED described in corresponding plant-grid connection shines mould Block 3.

In the present embodiment, the switching module 5 includes switching switch 53, the first power supply circuit 54 and the second power supply circuit 55, first power supply circuit 54 and second power supply circuit 55 it is in parallel and with the switching switch 53 electric connection, institute The power supply line for stating USB interface 4 is electrically connected with the switching switch 53, and the switching switch 53 is connect with 1 signal of processor. In the present embodiment, the maximum current that first power supply circuit 54 provides is 0.5A, what second power supply circuit 55 provided Electric current is not less than 0.9A.
