Description
Technical Field

In addition, the crush pattern of the prior art crash cans is not stable in high speed frontal impacts and the problem is more pronounced in high speed offset impacts. Under high-speed offset collision, the collision side usually has a fracture phenomenon, and the non-collision side usually does not deform due to a strong structure, and integrally inclines under a lateral tension force, so that a bolt connected with the front longitudinal beam is pulled off, or a welding spot is directly torn.
The energy absorption box is not easy to deform in the collision of the two-wheeled vehicle, so that the collision strength of the two-wheeled vehicle is high, and passengers of the two-wheeled vehicle are seriously injured; instability of the collision behavior of the vehicle in a high-speed collision can result in uncontrolled actuation times of the restraint system, which in turn can lead to a considerable loss of protection of the restraint system.
