Protection device for driver during emergency braking of automobile

Abstract

The invention discloses a protection device for a driver during emergency braking of an automobile, and belongs to the technical field of automobile safety. The protection device comprises a half-frame base, two sets of C-shaped steel, two sets of left welding blocks, two sets of right welding blocks and two sets of lifting hydraulic rods. Openings of the two sets of C-shaped steel are oppositelyand horizontally fixed to the front side and the rear side of a top opening of the semi-frame base; the two sets of left welding blocks are welded to the left ends of inner cavities of the two sets ofC-shaped steel correspondingly. A forward and reverse motor rotates backwards such that a nut of a ball screw moves leftwards; meanwhile, when the inertia force is small, a first telescopic spring isused for buffering the seat; a speed increasing device can provide three ball screw rotating speeds; within the same time, the nut moving distances of the ball screws are different, then the compression amount of a second telescopic spring is changed, the reverse acting force is rapidly increased, speed reduction is facilitated. The device is automatically and manually combined, operation is convenient, a driver and passengers are protected in the speed reduction process, and safety is high.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a protection device for a driver when the automobile suddenly brakes. Background technique [0002] Today, automobiles have become an integral part of human life. For example, exciting racing is one of the most popular sports in the world. It is divided into the following categories: Long-distance races: from A to Long-distance races in the second place, including rally and cross-country races; ring track races: that is, ring track races where the starting point and the end point are at the same place. One of them is road racing, which is divided into formula racing, sports prototype racing, etc., and the most exciting is Formula One racing; no road racing: no road racing on a dirt field, however, when people enjoy it to the fullest While the passion, comfort and convenience brought by the car, it has to taste the bitter fruit brought by it again and again-the huge los...
