Abstract

A power-free wireless operation device of a portable electronic device includes a portable electronic device that includes a device-side matching unit, a radio frequency unit, a device-side wireless communication interface, and a message processing unit and a wireless operation mechanism that includes a matching unit, a current processing unit, a wireless communication interface, and an operation processing unit. As such, a keyboard is operable with power supply from a portable electronic device so that the keyboard does not need to be equipped with an own power supply, whereby the present invention allows for significant reduction of the size of a wireless operation device and, in manufacture and production, a design can be adopted to achieve the features of being light, thin, and compact and being readily foldable for easy carrying and providing an effect of environmental protection through regeneration.

Claims

1. A combined operation system, comprising a portable electronic device and a wireless operation mechanism operable in combination with the portable electronic device, wherein:

the portable electronic device comprises;

a device-side matching unit, which functions for impedance matching and supplying radio frequency energy to the wireless operation mechanism;

a radio frequency unit, which is connected to the device-side matching unit for supplying electric power;

a device-side wireless communication interface, which is connected to the device-side matching unit for achieving wireless connection; and

a message processing unit, which is connected to the device-side wireless communication interface for analyzing and converting information; and

the wireless operation mechanism comprises;

a matching unit, which is for impedance matching with the device-side matching unit to acquire the radio frequency energy;

a current processing unit, which is connected to the matching unit to proceed with rectification of the acquired radio frequency energy into electric power;

a wireless communication interface, which is connected to the matching unit and the current processing unit and, after receiving electrical power, proceeds with handshaking communication with the device-side wireless communication interface; and

an operation processing unit, which is connected to the current processing unit and the wireless communication interface and, after receiving electrical power, is operable to generate an input instruction that is applied, through the wireless communication between the wireless communication interface and the device-side wireless communication interface, to the portable electronic device for analysis and conversion performed with the message processing unit to execute the input instruction in the portable electronic device.

2. The combined operation system according to claim 1, wherein the device-side wireless communication interface comprises a near field communication unit and a Bluetooth communication unit.

3. The combined operation system according to claim 1, wherein the current processing unit comprises a rectifier and a voltage regulator connected to the rectifier.
