Abstract

The invention provides an automobile front device based on pedestrian protection and relates to an automobile front device. When a pedestrian collides with an automobile, due to the arrangement of the positions of a front bumper, an engine cover and a windshield of the automobile, the pedestrian is likely to be seriously harmed, and serious losses of both an automobile driver and the pedestrian are caused. The automobile front device comprises a front elasticity adjusting assembly, a bottom board, a trigger rod, a cam mechanism and a lifting mechanism. The front bumper of the automobile is fixedly installed on the bottom board through the front elasticity adjusting assembly. The trigger rod is located on the bottom board, the front end of the trigger rod is fixedly connected with the front bumper, the rear end of the trigger rod is hinged to the cam mechanism, the lifting mechanism is arranged above the cam mechanism, the cam mechanism is connected with the engine cover of the automobile through the lifting mechanism, and the engine cover of the automobile inclines towards the front bumper under the adjustment effect of the lifting mechanism. The automobile front device is used at the front portion of the automobile.

Description

technical field [0001] The invention specifically relates to a vehicle front device based on pedestrian protection. Background technique [0002] In today's frequent traffic accidents, pedestrians, as the most vulnerable vulnerable group, need to be protected, and all walks of life are paying more and more attention to protecting pedestrians from persecution in traffic accidents. In traffic accidents, the head and lower limbs of pedestrians are very likely to be injured, of which the head accounts for about 31.70% of the total, and the lower limbs account for about 28.80% of the total. Head and lower limb injuries are the most common injuries suffered by pedestrians in traffic safety accidents. main damage. [0003] Domestic and foreign traffic safety researchers have done a lot of research on the protection of the head and lower limbs of pedestrians. The research shows that the structural parameters of the bumper can have a very significant impact on the damage of the lowe...
