Problems solved by technology

Although it uses a carbon fiber-steel hybrid structure door, it uses a carbon fiber anti-collision beam and does not design a stable connection structure in the middle of the anti-collision beam, which cannot guarantee the collision performance requirements
In addition, although it reduces the weight of the door to a certain extent, because the outer panels are still made of metal materials, the weight reduction effect is average.

Abstract

The invention discloses a carbon fiber-steel mixed vehicle door. The vehicle door comprises an automobile door outer plate, an automobile door inner plate, a window frame and an anti-collision beam, wherein the automobile door outer plate covers the automobile door inner plate, the window frame and the anti-collision beam are arranged between the automobile door outer plate and the automobile doorinner plate, the automobile door outer plate and the automobile door inner plate are made of carbon fiber composite materials, and the window frame and the anti-collision beam are made of steel. Themiddle of the anti-collision beam is connected with the automobile door outer plate through a connecting piece, the two ends of the anti-collision beam are bonded with the automobile door inner platethrough structural adhesives, and one end of the anti-collision beam is fixedly connected with the window frame. The invention further discloses a vehicle which comprises the carbon fiber-steel mixedvehicle door.

Description

technical field [0001] The invention relates to automobile lightweight, in particular to a carbon fiber-steel hybrid door and a vehicle. Background technique [0002] With the increase of car ownership in the world, a series of problems such as energy shortage and environmental pollution have become increasingly prominent. Lightweight vehicles can reduce vehicle quality, improve fuel efficiency / cruising range, and reduce costs. Traditional fuel vehicles have increasingly urgent requirements for fuel consumption regulations and new energy vehicles for cruising range, and the lightweight of vehicles has ushered in a new round of development opportunities. [0003] The door is one of the important parts of the car body. The door not only needs to match many interior and exterior decorations, electrical equipment and other parts, but also has a crucial impact on the collision performance of the vehicle. At present, automobile doors are generally made of steel through sheet met...
