A structure for preventing a terminal screen from being damaged during falling comprises a terminal body, and an air channel and a sensor that are disposed in the terminal body. A fan is disposed in the air channel. The sensor is electrically connected to the fan by using a main control chip in the terminal body. The sensor can receive a signal indicating that the terminal body falls to the ground and control the fan to be turned on or turned off by using the main control chip. An air inlet and an air outlet are respectively formed at two ends of the air channel. The air outlet of the air channel is formed on the terminal body. The structure can relieve a force generated when the terminal screen hits the ground during falling.
