Abstract

A multifunctional emergency rescue device includes a main control circuit, a selection switch, an indicator lamp, an annunciator, a battery unit, a connection port module, an external power input socket and output socket. The main control circuit contains a micro control unit (MCU), a power sensing unit, a rectifier and regulator unit, a monitoring unit, and a vibration induction unit. When the selection switch is switched to a first working mode, recharging, rescue, a stable operation to a car electric system are performed. When a second working mode is switched to, electronic devices are recharged at the USB port and the LED lighting lamp illuminates. When a third working mode, an emergency mode, is switched to, the vibration induction unit generates a signal determined by the MCU to drive the annunciator to generate an alarm sound, achieving functions of emergency calling, disaster calling and burglar-proof calling.

Claims
