Automobile Pedestrian Leg Guards

Abstract

The invention discloses a pedestrian leg protection device of an automobile. The pedestrian leg protection device is arranged at the front end of the automobile and comprises a support beam and two or more buffer fixing assemblies, wherein each buffer fixing assembly comprises a support fixing part, a connecting part and a buffer part; the connecting part comprises a first connecting section, a second connecting section opposite to the first connecting section, and a third connecting section connected between the first connecting section and the second connecting section; the first connecting section is connected to the support beam; the second connecting section is connected to the buffer part; one end, far away from the second connecting section, of the buffer part is fixedly connected to the front end of the automobile; the third connecting section is provided with a rotary shaft; the connecting part is rotatably connected to the support fixing part by taking the rotary shaft as a rotary center; one end, far away from the third connecting section, of the support fixing part is fixedly connected to the front end of the automobile. According to the pedestrian leg protection device, a pedestrian can be prevented from being involved in the bottom of the automobile and the risk of lower limb tibial fracture of the pedestrian can be effectively lowered.

Description

technical field [0001] The invention relates to the technical field of automobile protection structures, in particular to an automobile pedestrian leg protection device. Background technique [0002] According to research data, when a pedestrian collides head-on with a moving vehicle, more than 80% of the accidents will cause the lower limbs of the pedestrian to be injured. The front beam assembly of the device and the spoiler area under the front beam assembly are provided with pedestrian leg guards. After the lower limbs are in contact with the vehicle, the front cross member assembly and the pedestrian leg protection device can absorb energy to a certain extent, and the pedestrian leg protection device can distribute part of the impact force brought by the tibia of the lower limbs to the vehicle body. At the same time, the pedestrian leg protection device also has the function of preventing pedestrians from being involved in the bottom of the vehicle. [0003] Pedestria...

AI Technical Summary

Problems solved by technology

[0003] Pedestrian leg protection devices in the prior art are generally plastic support plates or steel support members, mainly to prevent the intrusion of pedestrians' lower limbs, but the existing pedestrian leg protection devices still have poor energy absorption effect, and the pedestrian's lower limbs are injured. Among injuries, tibial fractures remain a common type of injury
