A fast folding anti-collision type electric vehicle bumper assembly

Abstract

The invention provides a quick folding anticollision type electric car bumper assembly. The quick folding anticollision type electric car bumper assembly is characterized in that two foldable shafts are connected on the front plane of the bumper body component of the quick folding anticollision type electric car bumper in a fastening mode, a hinge shaft is arranged in the middle of each foldable shaft, each foldable shaft is divided into a front section and a rear section by the corresponding hinge shaft, the rear ends of the rear sections are inserted into matched holes of the bumper body of the bumper body component, and are firmly welded to the bumper, and the front ends of the rear sections are connected with the hinge shafts. The rear ends of the front sections of the foldable shafts are connected with the hinge shafts, and the front ends of the front sections are inserted into outer sleeve shaft tubes, and can axially slide in the outer sleeve shaft tubes. The outer sleeve shaft tubes are inserted into shaft holes of a base on a car body and are firmly welded, the two foldable shafts can be pulled out of and pushed in the outer sleeve shaft tubes on the car body after being straightened, the bumper component can be rotated and folded downwards with the hinge shafts as the center after being pulled out in place, and space channels are provided for a battery module pulled out of the rear portion of the electric car.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and more specifically relates to a bumper assembly technology of an electric vehicle in which a battery module is replaced from the rear. Background technique [0002] With the development of society, the problems of limited oil resources and environmental pollution have become increasingly prominent, which makes electric vehicles attract more and more attention from all walks of life, and electric vehicles have become the direction of future automobile development. One of the key technologies in electric vehicles is the energy supply problem. To solve this problem, the industry has developed a power battery module that can be replaced quickly, which can solve the energy supply problem of electric vehicles through commercial distribution. This scheme has been discussed in detail in the "ZL2011202588274" patent; so how to load it? One of the solutions is to install the power battery mod...
