All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that, if directional indications (such as up, down, left, right, front, and rear … …) are included in the embodiments of the present invention, the directional indications are merely used to explain the relative positional relationship, movement conditions, etc. between the components in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are correspondingly changed.
In addition, if there is a description of "first", "second", etc. in the embodiments of the present invention, the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and/or" as it appears throughout includes three parallel schemes, for example "A and/or B", including the A scheme, or the B scheme, or the scheme where A and B are satisfied simultaneously. In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed in the present invention.
The ultimate goal of automotive safety research is to avoid or mitigate injuries suffered by drivers and pedestrians during traffic accidents. In a real traffic accident, the front collision incidence rate of which the overlapping rate is smaller than 25 percent is higher (the ratio is 24.4 percent), and because the main energy absorption and force transmission components are not in the overlapping area, the IIHS reports that 25 percent of the death of the front collision is caused by small offset collision. When a small offset collision occurs to an automobile, the automobile body needs to have enough energy absorption and collision rigidity so as to improve the protection of passengers on the automobile.
The percentage of 25% refers to the overlap amount of the vehicle body width and the barrier. The smaller the overlap amount, the smaller the contact force bearing area, the higher the injury to the vehicle body and passengers is possible, and the 25% offset collision is small due to the front contact overlap, and the front longitudinal beam basically does not participate in deformation energy absorption, but only a small amount of bending deformation. If the front impact beam is shorter, the impact beam may not participate in the transfer of impact energy. Finally, the path actually participating in energy absorption is likely to be the only upper longitudinal beam inside the front fender. Secondly, the tire is susceptible to intrusion. The tire is stressed earlier and more in a small offset collision, and the dash panel and the door sill Liang Geng are subject to deformation, resulting in more serious intrusion of the tire into the passenger compartment.
