Active-extension energy-absorption bumper of minibus

Abstract

The invention discloses an active-extension energy-absorption bumper of a minibus, wherein the active-extension energy-absorption bumper of the minibus lowers damage to a minibus body and injuries to a driver and passengers and improves safety. The active-extension energy-absorption bumper of the minibus comprises a left frame carling, a right frame carling and a bumper body, wherein the bumper body is arranged at the front end of the left frame carling and the front end of the right frame carling. The active-extension energy-absorption bumper of the minibus further comprises an energy absorption device and an active extension mechanism, wherein two threaded barrels of the energy absorption device are designed to be respectively provided with a smooth cylindrical hole start segment and a threaded hole main body segment; forward guiding cylinder heads at the rear ends of two drop bars are matched with inner diameter cylindrical surfaces of the threaded hole main body segments for installation; backward ejecting cylindrical sections at the rear ends of the two drop bars are matched with the smooth cylindrical hole start segments for installation; the smooth cylindrical hole start segments are matched with each other for clamping a shearing sleeve; the active extension mechanism is arranged at the rear ends of the two threaded barrels. The active-extension energy-absorption bumper of the minibus is applicable to minibus bumper energy-absorption area increase by means of active extension and impact energy absorption.

Description

technical field [0001] The invention belongs to an automobile bumper, and more specifically relates to an actively extending energy-absorbing bumper for a van. Background technique [0002] With economic development and scientific and technological progress, cars have entered more and more families. The number of cars keeps increasing, the performance of cars has made a qualitative leap, and the road conditions have also been greatly improved. The speed of cars running on the road is getting faster and faster, followed by a sharp rise in the accident rate, which will not only cause huge property losses, but also threaten the lives of drivers and passengers. Therefore, the study of automobile crash safety is a big problem that cannot be ignored. The collision accident rate of the front of the car accounts for more than 60% of the total accident rate. Its hazards are also quite large. Among the types of automobiles, vans are the most harmful when they collide. In more and...

AI Technical Summary

Problems solved by technology

Among the types of automobiles, vans are the most harmful when they collide. In more and more van accidents, because the front structure of the van has no engine compartment, there is not enough area to absorb the collision energy during the collision, resulting in Casualties to the driver and co-pilot of the
