Abstract

The invention relates to a power-saving USB keyboard. The keyboard comprises a keyboard body and a storage battery; when a mobile device is connected and has an external power supply, the storage battery of the keyboard body is automatically charged; when the mobile device does not have the external power supply, a battery of the mobile device is in short supply, and the storage battery of the keyboard body automatically supplies power to the mobile device; and the storage battery of the keyboard body can be directly connected with the external power supply to be charged through a USB data line. The storage battery in the keyboard body can be replaced. An LED lamp is arranged on the keyboard body, so that when in a low-power state, the mobile device is automatically powered and the LED lamp is turned on to prompt a user. The keyboard body is provided with a vibration inductor, so that when the keyboard body has a slight vibration, a working state of the keyboard body is enabled.

Description

technical field [0001] The invention belongs to the field of accessories for electronic products, and in particular relates to a USB power-saving keyboard. Background technique [0002] Keyboards are common accessories for mobile devices such as computers. Connect to a computer through a data cable, and input instructions to the computer. Under normal circumstances, the keyboard itself does not have a power supply system. After connecting to the mobile device of the scanner, it relies on the power consumption of the mobile device to work. However, due to the continuous enhancement of functions of mobile devices, the power consumption of mobile devices is also getting higher and higher. There is no need to worry if there is an external power supply connected, but if it is outdoors or without an external power supply, it will consume a lot of power; carrying a mobile power supply will also take up extra space. Therefore, how to make the mobile device obtain sufficient power...
