Technical Field

The invention relates to the field of keyboards, in particular to a keyboard with a built-in USB charging device.

Background

A keyboard is a command and data entry device used to operate equipment and also refers to a set of function keys arranged to operate a machine or equipment through the system. The keyboard is also a part of a keyboard musical instrument, and may also refer to a musical instrument using a keyboard, such as a piano, a digital piano, or an electronic organ, etc., which is useful for practicing typing. The keyboard is the most common and main input device, and english letters, numbers, punctuations and the like can be input into the computer through the keyboard, so as to send commands, input data and the like to the computer.

At present, a wired keyboard is mostly connected with devices such as a computer by adopting a USB wire, and the USB is a novel interface technology applied to the field of computers. The USB interface has the characteristics of higher transmission speed, hot plugging support and connection of a plurality of devices. The output voltage and current of the USB interface are: +5V500mA has an error, which cannot exceed +/-0.2V at most, i.e. 4.8-5.2V, and there are three types of USB interfaces: USB1.1, USB2.0 and USB 3.0. Theoretically, the transmission speed of the USB1.1 can reach 12Mbps, the speed of the USB2.0 can reach 480Mbps, and the USB1.1 can be downward compatible. In these years, with the popularization of a large number of personal computers supporting USB, USB has become a standard interface of personal computers. At the host end, the newly introduced personal computers support almost 100% of USB; on the peripheral side, devices using USB interfaces are increasing, such as digital cameras, scanners, joysticks, magnetic tapes and floppy drives, imaging devices, printers, keyboards, mice, etc.

Along with the popularization of smart phones, people pay more and more attention to the charging of the mobile phones, the charging line interface of the smart phone is also a USB interface, the charging voltage of the charging line interface is also 5V, and only the charging current of a charging plug of the mobile phone is usually large, so that the charging line interface can be charged fully quickly, and the working voltage of the existing keyboard USB interface is also 5V, so that the existing keyboard can be improved to meet more requirements.
