Low-strength impact bumpers can cope with it, while high-strength impact bumpers play the role of force transmission and dispersion and buffering, and finally transfer to other structures of the body, and then rely on the strength of the body structure to resist. The front and rear bumpers have a certain energy-absorbing effect in high-speed collisions, but they are not the main energy-absorbing parts.
