The invention belongs to the technical field of living equipment and relates to a severe foot injury distress signal auto-transmitting mechanism, comprising a power generator, a moving pole, an electricity storage device, a controller, a wireless signal receiver, a cellphone, a central processing unit, a wireless signal transmitter, a heater, a massage device, an illuminator, a radar device, a USB (universal serial bus) power output port, an alarm, and a stress sensor. All of the power generator, the moving pole, the electricity storage device, the controller and the wireless signal receiver are disposed in a volumetric chamber, and the central processing unit and the wireless signal transmitter are disposed on the cellphone. In the invention, when a human body walks, the power generator may be driven and pushed to generate electricity through vertical movement of the moving pole. The severe foot injury distress signal auto-transmitting mechanism is reasonable in structure, simple in design and applicable to the design of severe foot injury distress signal auto-transmitting mechanisms.
