Novel lampshade mechanism capable of optimizing pedestrian protection of whole vehicle

The utility model provides a novel lampshade mechanism capable of optimizing pedestrian protection of a whole vehicle, which comprises an internally-matched milky white sheet constructed between an arc-shaped reflector and a housing, and an internally-matched high-reflection white sheet is arranged below the internally-matched milky white sheet; the section is made along the center line of the lampshade mechanism, and the distance between the lampshade white piece of the housing and the intersection point of the internally-matched milky white piece and the internally-matched high-reflection white piece is 3 mm. The internally-matched milky white piece sequentially comprises an acute angle transition area, an ascending area and a horizontal area in the height direction, an obtuse angle inflection point is formed between the acute angle transition area and the ascending area, the distance between the lampshade white piece of the housing and the obtuse angle inflection point is 5 mm, and the distance between the
