Since the V-shaped design has a certain directionality, it can provide more effective protection in collisions at different angles. Whether the collision is from the front, side or oblique direction, it can guide the collision force to a certain extent and reduce In order to reduce the damage to the vehicle body, on the premise of meeting the strength and rigidity requirements, the mounting beam 302 and the protective cover 301 are made of lightweight materials, which helps to reduce the weight of the anti-collision mechanism 3, so that the sum of the weight of the anti-collision mechanism 3 and the tail cover 6 reaches the overall requirement of the rear counterweight, thereby improving fuel economy. Furthermore, a reinforcing beam 304 is arranged at the center of the mounting beam 302, and the reinforcing beam 304 is arranged in an Ω shape.
