Abstract

The invention discloses a connecting structure for square tube aluminum profiles, which comprises a parallel connection mode and a vertical connection mode. The parallel connection mode comprises connecting pieces and nuts, and rigid connection is realized by threaded connection of the connecting pieces. The vertical connection mode comprises connecting plates and rivets, and the rigid connection is realized by rivet connection of the connecting plates. According to the connecting structure for the square tube aluminum profiles, the traditional aluminum soldering technology for connecting the square tube aluminum profiles is replaced by the connecting pieces or connecting plates, so that the problems of structural deformation and poor strength arising from the aluminum soldering technology are solved; connecting fastness and reliability between the square tube aluminum profiles are ensured; the connecting precision is easy to control; the connecting pieces or the connecting plates are sunk between the upper surfaces and the lower surfaces of the square tube aluminum profiles, so that requirements of whole vehicle design and performances of motor vehicles are met; and the whole vehicle quality is improved.

Description

technical field [0001] The invention belongs to the field of motor vehicle body frame connection, and in particular relates to a connection structure of square tube aluminum profiles of the body frame. Background technique [0002] In the prior art, the frame of the car body is mostly steel frame, which leads to a relatively heavy body weight. According to calculations, if the weight of the car is reduced by 10%, the fuel consumption can be reduced by 6% to 8%. To significantly reduce greenhouse gas emissions, it is necessary to find suitable alternative materials to reduce the weight of the vehicle body. Among many materials, aluminum and its alloys have the advantages of good formability, corrosion resistance, surface coloration, light weight and high strength, which make square tube aluminum profiles widely used in the automotive field. However, the welding process is generally used for the connection of square tube aluminum profiles. However, the deformation of aluminum...
