Abstract

The present invention provides a tilting sensing and safeguarding mechanism of the electric scooter cart. The mechanism includes a central processor, electrically connected with the throttle controller of the electric scooter cart, and a gravity sensor, used to sense the tilting state of the electric scooter cart and transmit the sensing signals to the central processor. There is a light control module, electrically connected with the central processor. The central processor enables the light control module to execute the respective command according to the tilting sensing signal of the gravity sensor. A light display screen is controlled by the light control module to determine the ON/OFF state of the lights. A speed control module generates a control signal for controlling the motor controller of the electric scooter cart, so as to adjust automatically the operating speed/state of the motor. The mechanism detects the tilting states of the electric scooter cart.
