Automobile bumper device with extended function

Abstract

The invention discloses an automobile bumper device with an expansion function. The device comprises a bumper (1) and two bumper expansion components (2), and the two bumper expansion components are respectively mounted at two ends of the bumper; a trigger part is arranged on the bumper expansion assembly and located in front of the bumper, and when the trigger part moves towards the bumper under the action of an external force, the bumper expansion assembly can expand in the extension direction of the end of the bumper; and an expansion locking mechanism is further arranged between the bumper expansion assembly and the bumper, and when the bumper expansion assembly is expanded to the extending direction of the bumper, the expansion locking mechanism can lock the bumper expansion assembly and the bumper and combine the bumper expansion assembly and the bumper into a whole. The bumper device can be expanded when collision occurs so that the collision force is greatly dispersed, the damage of collision impact to the whole structure of the vehicle is reduced, and the personal safety of a driver and passengers in a compartment is fully protected.

Description

technical field [0001] The invention relates to an automobile bumper, in particular to an automobile bumper device with extended functions. Background technique [0002] Bumpers are installed at the front and rear of the existing car, so that the car can ensure the overall anti-collision deformation ability of the car in the event of a collision, thereby playing a good role in protecting the personal safety of the drivers and passengers in the car. [0003] The configuration of the vehicle bumper is affected by various demands such as beautiful appearance, weight reduction, and pedestrian protection. The protection range of the bumper, or the protection area, is not very large. When two vehicles collide, due to the small protection range of the bumper, the impact area when the two vehicles collide is small, and the collision force will be more concentrated, which leads to the fact that the energy-absorbing structures of the two vehicles cannot fully exert their absorption. ...

AI Technical Summary

Problems solved by technology

When two vehicles collide, due to the small protection range of the bumper, the force area of ​​the two vehicles colliding is small, and the impact force will be relatively concentrated, which leads to the failure of the energy-absorbing structures of the two vehicles to fully absorb Due to the effect of collision impact energy, the two vehicles will cause a certain degree of damage to each other. For vehicles with smaller models, if the protection range of the bumper of the other large vehicle is small, the impact force on the small vehicle will be greater. It will be very concentrated, which will cause greater damage to the car, and then threaten the personal safety of the drivers and passengers in the car

[0004] In view of the above-mentioned problems, as long as the structural size of the bumper is increased, the protection range can be expanded. However, due to the limitation of the vehicle structure, the structural size of the bumper in the normal vehicle structure cannot be very large
