Vehicle driving early warning device

Abstract

The invention discloses a vehicle driving early warning device. The vehicle driving early warning device comprises mounting cavities formed in two sides of the lower end of the tail portion of a vehicle, the mounting cavities are each internally and separately provided with a mounting plate, side plates arranged symmetrically, an energy absorbing layer, a first steel plate, a connecting piece, a hydraulic cylinder, a second steel plate, an extension spring, a compression spring mounting groove, a compression spring, an aluminum foam layer, foam cotton and a fender. The output ends of the hydraulic cylinders are extended out, the second steel plates are pushed out along the sliding grooves, the impact from the rear of the vehicle is effectively buffered by arranging the foam cotton, the impact is dispersed by arranging the aluminum foam layer, the second plate plays a role of shock absorption by arranging the compression springs, the pressure brought by the impact on the hydraulic cylinders is protected by arranging the extension springs, and the impact can be released by arranging the energy absorbing layers. The vehicle driving early warning device absorbs and releases the pressure through the arrangement of multiple buffer energy absorbing structures, and plays a protective role for a vehicle body.

Description

technical field [0001] The invention relates to the technical field of vehicle running early warning, in particular to a vehicle running early warning device. Background technique [0002] With the development of highways and the improvement of automobile performance, the speed of automobiles has also increased accordingly. In addition to the increase in the number of automobiles and the increasingly busy traffic, the casualties and property losses caused by the increase in automobile accidents have become a social problem that cannot be ignored. The driving safety of automobiles is even more important. [0003] Traditional passive safety measures, such as setting seat belts, airbags, bumpers, etc., have been far from fundamentally avoiding the harm caused by traffic accidents. Therefore, active safety that enables cars to take active measures to avoid accidents has already It has become an important part of the current development of automobile technology. Active safety i...
