The vibration switch SW1 is electrically connected with a timing device. Wherein broken glass actuating mechanism makes broken glass ware begin to carry out the mechanism broken glass promptly. Specifically, if the electronic ignition head is used for breaking the glass by igniting gunpowder in the broken glass head, the gas generator, the energy storage tube and the cylinder are used for breaking the glass by pushing the broken glass head, and the like.

The timing device in this embodiment is a decoding singlechip IC 1.

Thus, when the passenger car runs, the engine runs to cause the vehicle to vibrate, so that the vibration switch SW1 senses the vibration and transmits a signal to the control circuit for the glass breaking device, and the control circuit starts to receive the glass breaking signal. When the passenger car stops running and the shock stops (no passenger is on the car and glass breaking is not necessary), the shock switch SW1 senses the shock signal to stop, the signal is transmitted to the control circuit for the glass breaking device, the single chip microcomputer in the control circuit for the glass breaking device is closed, the single chip microcomputer enters a dormant state, the glass breaking device is in a closed energy-saving state, and the service life of the power supply of the glass breaking device is greatly prolonged.
