Light-weight aluminum alloy frame

Abstract

The invention discloses a light-weight aluminum alloy frame, which comprises a pair of head frame edge beams, wherein the two front frame edge beams are sequentially connected with an anti-collision rod, a head frame connecting beam A and a head frame connecting beam B from front to back; the head frame connecting beam A and the head frame connecting beam B are all the stamping parts with cross section in the ' [' structure; the middle frame part comprises an elliptical ring beam, and the long axis of the elliptical ring beam is parallel to the length direction of the light-weight aluminum alloy frame; the right inner side and the left inner side of the elliptical ring beam are sequentially connected from front to back by the middle frame connecting beam A and the middle frame connecting beam B which are parallel to the short axis of the elliptical ring beam; the front and back side of the elliptical ring beam are arranged with reinforcing ribs respectively; the tail frame part comprises a pair of tail frame side beams, and a tail frame connecting beam A and a tail frame connecting beam B are sequentially connected between the two tail frame edge beams from front to back; The tailframe connecting beam A and the tail frame connecting beam B are all stamping parts with the cross section in the' [' structure. The light-weight aluminum alloy frame has the beneficial effects that the overall weight can be reduced under the condition of unchanged frame strength.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a lightweight aluminum alloy vehicle frame. Background technique [0002] Whether it is a traditional car or a new energy vehicle, lightweight design has become a research hotspot in the industry. For passenger cars, lightweight design has greater meaning and higher requirements. With the continuous research and development and use of new materials, the lightweight problem of the car body seems to see the light of day. [0003] High-strength materials such as carbon fiber are especially suitable for the manufacture of lightweight car bodies. However, due to the current constraints on technology and production capacity, the cost of carbon fiber remains high. Therefore, carbon fiber materials can only be used in very few parts of the car body, contributing to the overall weight reduction of the car body. Small, can not solve the lightweight problem. Aluminum alloy...

AI Technical Summary

Problems solved by technology

[0004] However, in the current automobiles made of aluminum alloy, although the frame part is made of aluminum alloy instead of alloy steel, the weight of the whole vehicle is greatly reduced, but the strength of the frame still needs to be improved due to structural problems.

For example, most of the current common vehicle frames include two longitudinal beams running through the length direction, and multiple cross beams are arranged in sequence between the longitudinal beams. The defect of this vehicle frame is that the ability to withstand impact in the lateral direction is very low. Frame rails are easily deformed when impacted on one side

If you want to increase the strength, you need to add more beams, which will undoubtedly increase the weight
