The impact force in front, dispersed the power from the front bumper to the energy suction box on both sides, and passed it to the left and right front longitudinal beams, and then passed to other structures of the body. the rear is hit, and the collision force is transmitted from the rear bumper to the energy -absorbing box on both sides to the left and right longitudinal beams, and then passed to other structures of the body. the low -intensity impact bumper can cope with, and the high -intensity impact bumper plays the function of transmission and buffering of strength. finally, it is passed to other structures of the body, and then resisted by the strength of the body's structure.
