After home appliances have been sufficiently popularized, emphasis on consumer consumption is being turned to large-scale housing and automobiles. It is with this trend that the automotive industry has maintained a fairly high growth rate in recent years. The number of people per automobile is increased, so that the occurrence rate of traffic accidents is also increasing year by year. 50 thousands of traffic accidents occur in China each year, and the number of dead traffic accidents exceeds 10 ten thousand, which is equivalent to a small county and is the first in the world. Statistics show that every 5 minutes there is a loss of body wheels and every 1 minute there is disability due to traffic accidents. The economic loss caused by traffic accidents reaches hundreds of billions of yuan each year.
The anti-collision beam of the vehicle is particularly important to the protection effect of the vehicle when a traffic accident, especially an impact accident, occurs. The two ends of the existing automobile anti-collision beam are connected with low-speed energy absorption boxes with very low yield strength, and then are connected to the automobile body longitudinal beam through bolts. The low-speed energy absorption box can effectively absorb collision energy when a vehicle collides at a low speed, so that the damage of the impact force to the longitudinal beam of the vehicle body is reduced as much as possible.
