Wireless charging device capable of preventing stealing of mobile phone in wireless charging

Abstract

The invention relates to the technical field of a wireless charging device, and particularly to a wireless charging device capable of preventing stealing of a mobile phone in wireless charging. The working principle of the wireless charging device is characterized in that after a fingerprint acquisition module performs fingerprint information acquisition, the fingerprint acquisition module transmits the acquired fingerprint information to a single-chip microcomputer for storage; when unlocking of the mobile phone is required, the fingerprint information which is acquired again is transmitted to the single-chip microcomputer; the single-chip microcomputer performs comparison for determining whether the two pieces of fingerprint information are same, thereby making an alarm module perform alarming or not; a Bluetooth module sets a Bluetooth signal detecting distance to a fixed number; when the mobile phone leaves the Bluetooth module on the condition of unlocking, and the detecting distance set by the Bluetooth module is exceeded, Bluetooth signal connection with the Bluetooth module is off; the Bluetooth module performs feedback of a switching-off signal to the single-chip microcomputer; and the single-chip microcomputer makes the alarm module perform alarming.
