A collision detection apparatus is provided, which includes a main body, at least an air bag disposed at the periphery of the main body and at least a baro sensor. The air bags communicate with each other. The air bag is connected to the baro sensor to detect the pressure at different time points and the pressure variations. The apparatus judges whether a collision has occurred and the collision force is detected by the baro sensors. The time point of collision occurrence and the collision position according to the pressures of the air bags at different time points are determined.
