Automobile front anti-collision protecting structure

Abstract

The invention provides an automobile front anti-collision protecting structure. The automobile front anti-collision protecting structure comprises a front bumper with the two ends connected with the front of an automobile body, a radiator longitudinal beam assembly assembled on a front wall of the automobile body, a front anti-collision beam assembly located behind the front bumper, and an upper supporting beam located behind the top of the front bumper. The two ends of the front anti-collision beam assembly are connected with the radiator longitudinal beam assembly, and the two ends of the upper supporting beam are connected with the radiator longitudinal beam assembly through two upper installing supports. The automobile front anti-collision protecting structure further comprises a lower supporting beam located behind the bottom of the front bumper, wherein the two ends of the lower supporting beam are connected with the radiator longitudinal beam assembly, and the horizontal distance between the front bumper and the lower supporting beam is not larger than 15 mm. The horizontal distance between the upper supporting beam and the front bumper is not larger than 15 mm. Good safety is achieved, when an automobile collides with a pedestrian during running, the upper supporting beam and the lower supporting beam can collide with the shanks and the thighs of the pedestrian respectively at the same time, the bending angle between the shanks and the thighs of the pedestrian is small, and damage, generated to the shanks and the knees of the pedestrian by the front anti-collision beam assembly when the shanks and the knees of the pedestrian collide with the front anti-collision beam assembly can be avoided.

Description

technical field [0001] The invention relates to an automobile anti-collision protection structure, in particular to an automobile front anti-collision protection structure. Background technique [0002] In recent years, the pedestrian protection performance of automobiles has received more and more attention and attention. Europe and Japan have formulated and implemented regulations on pedestrian protection, and China also released the national recommended standard GB / T24550 "Collision Protection of Automobiles to Pedestrians" based on the Global Technical Standard for Pedestrian Collision Protection (GTR) in 2009, and pedestrian protection is listed in E-NCAP (European New Car Evaluation Standards) The score ratio requirements are also increasing year by year. If the car is to meet the E-NCAP five-star standard, the pedestrian protection score ratio only needs to be 25% in 2009, and 40% in 2010. By 2012 In 2015, the proportion of pedestrian protection score must reach 60%,...

AI Technical Summary

Problems solved by technology

Therefore, when a car collides with a pedestrian while driving, the upper support beam cannot contact the pedestrian's thigh to play a supporting role. Larger, the pedestrian's calf and knee may collide with the front anti-collision beam assembly in an instant, causing the front anti-collision beam assembly to hurt the pedestrian's calf and knee, and in severe cases, the pedestrian's calf and knee will be broken. to disable

Therefore, the security of this prior art is poor
