Automobile flexible shank collision supporting structure

Abstract

The invention discloses an automobile flexible shank collision supporting structure which comprises a mounting frame and a buffer plate arranged on the mounting frame, a sliding frame plate is fixedly connected to the front face of the mounting frame, and movable assemblies are slidably mounted on the left side and the right side of an inner cavity of the sliding frame plate correspondingly, the back of the movable assembly is fixedly connected with the front face of the mounting frame through a bolt. The invention relates to the technical field of automobile detection. According to the flexible shank collision supporting structure for the automobile, the mounting frame is fixed to the front cross beam of the automobile, during collision, primary buffering is conducted through the buffering plate firstly, then buffering is conducted through the movable assembly, finally buffering is conducted through the buffering grid assembly, buffering is conducted layer by layer, and the impact force generated by collision is buffered, therefore, the bending degree of the flexible shank is reduced, the index of the flexible shank is ensured to be in a normal range value, more accurate data is provided for a vehicle collision experiment, and research and judgment support is provided for reducing pedestrian lower limb injury.

Description

technical field [0001] The invention relates to the technical field of automobile detection, in particular to an automobile flexible shank collision support structure. Background technique [0002] In the field of automobile safety research, pedestrian protection is a very important part, and the design of pedestrian protection is related to the shape, layout and structure of the front end of the vehicle. Pedestrians are vulnerable groups in traffic, and pedestrians' legs are one of the most vulnerable parts. According to the survey, in the areas where pedestrians' injuries reach the simplified injury standard level 2 or above, the proportion of injuries to the lower limbs is 34%, while 44.2% % of lower extremity injuries are caused by front bumper collisions. In the event of a lower limb collision, the combination of collision force and possible axial torque of the leg can result in multiplied injuries. With the collision in front of the vehicle and the subsequent accelera...
