Rear anti-collision device for automobile

Abstract

The invention discloses a rear anti-collision device for an automobile comprising a plastic cushioning backing plate, a connecting plate and a cushioning plate, wherein the connecting plate is fixedly connected to the rear of the automobile by fastening screws; the outer surface of the connecting plate is fixedly provided with the plastic cushioning backing plate; the cushioning plate is in an elastic connection with fixing plates by buffer spring seats; the fixing plates are fastened and connected with the plastic cushioning backing plate by the fastening screws; an anti-collision airbag body is fixed on the inner end of the plastic cushioning backing plate; and a protective airbag is fixedly arranged in the interior of the anti-collision airbag body. When the automobile is parked at night, fluorescent rings of the rear anti-collision device achieve the aim of giving warnings to passing vehicles and pedestrians. When a collision occurs, the plastic cushioning backing plate is in contact with the rear of the automobile in a large area. Under the action of the plastic cushioning backing plate, the impact pressure is effectively reduced to ensure that the automobile is not deformed. When the impact force is too large, the anti-collision airbag body will be triggered to eject the protective airbag and reduce the impact force between the two automobiles so as to ensure the safety of automobiles and drivers. In addition, the rear anti-collision device has a simple structure.
