Embodiment Construction

[0017] figure 1 The scheme shown is a top view of a typical flipped bumper. The bumper (1) is arc-shaped and has a support on the back. The limit end (10) of bumper (1) both sides protrudes respectively 5 centimeters of front wheel (15) limit. Two of the four rotating pairs are symmetrically fixed on the left and right sides of the vehicle, and the other two are symmetrically fixed on the left and right sides of the bumper. The distance between the two swivel joints fixed on the vehicle is less than half the width of the vehicle, and the distance between the two swivel joints fixed on the bumper is half the width of the vehicle. Two equal-length struts (6) are staggered mutually, and one is on, and one is down, and the included angle between them and the projection of two front-wheel (15) center lines is respectively 40 degrees. The two ends of each pole (6) are respectively welded with the rotating sleeve (7) on the rotating pair, and the two ends of a pole (6) are respect...

Abstract

The invention discloses a bumper bar system which is designed by adopting novel thinking and used for protecting safety of drivers and passengers in vehicle collision. Impact force applied to left and right rotating pairs are not the same when a single edge of a front side of the vehicle is collided. Collision in the graph occurs on the left side, according to the balanced four connecting rod principle, a left rod pair (2) with big stress moves backward, and a right rod pair (3) with small stress warps upward, so that an included angle between impact directions of a bumper bar (1) and a collision object (22) becomes small, and the collision object (22) can slide along the inclined bumper bar (1) to a lateral side of the vehicle. When the collision occurs on the right side, similarly, the bumper bar (1) warps to the other side, and the collision object (22) slides to the other side of the vehicle. By the warped bumper bar, the vehicle can be protected from front impact by the collision object (22), safety of the drivers and passengers can be effectively protected.

Description

Technical field [0001] Aiming at the collision of vehicles, the present invention is a bumper system for protecting the safety of drivers and occupants, which is designed according to a new idea. Especially when the vehicle has a unilateral collision with a frontal overlap of less than 50% (hereinafter referred to as "unilateral collision"), the bumper (1) will turn up, so that the collision object (22) that hits the vehicle slides to the side of the vehicle, Avoiding frontal impact on the vehicle, effectively protecting the safety of drivers and passengers. Background technique [0002] According to statistics, most of the frontal collisions of vehicles are unilateral collisions, that is, collisions in which the frontal overlap of vehicles is less than 50%. What needs to be pointed out in particular is that the vast majority of two-vehicle collisions are unilateral collisions. When two vehicles collide, the speed of the collision is the superposition of the speed of the t...
