Aluminum profile connector and vehicle body framework

Abstract

The invention discloses an aluminum profile connector and a vehicle body framework. The aluminum profile connector comprises a connector body, wherein at least two joints are formed in the connector body at interval and are used for connecting an aluminum profile; each joint is formed by two opposite side plates extending in a direction far away from the connecting body; a hollow cavity is formed inside the connector body; a first reinforcing rib is arranged inside the cavity; and a second reinforcing rib is arranged between the two adjacent joints. The connecting body is high in strength, light in weight and low in processing cost, the joints and the aluminum profile can be screwed or pivoted, accurate positioning can be achieved, and flexible and diverse connection modes are available. The vehicle body framework comprises the aluminum profile connector. The end part of the aluminum profile is connected with the joints, accurate positioning, solid connection and convenient mounting and dismounting are achieved, deformation caused by welding is avoided, processing procedures are simplified, the working efficiency is improved, the connection integration degree of the high aluminum profile connector is achieved, the number of components is reduced, and convenience in mounting and transport is achieved.

Description

technical field [0001] The invention relates to the technical field of assembly parts, in particular to an aluminum profile joint and a body frame using the aluminum profile joint. Background technique [0002] The manufacturing process of the car body in the prior art generally uses sheet metal stamping parts to weld to form the car body skeleton. The overlapping edges are reserved between the sheet metals, and the connection between the skeletons is carried out by spot welding, which requires a large amount of molds and welding tooling, cost Higher, at the same time will produce welding deformation, reduce the structural strength, and the parts are numerous and complex. For example, passenger cars or electric vehicles are formed by direct tailor welding of profiles, and the use of secondary welding requires a large amount of welding tooling, high fixture costs, low production efficiency, large welding deformation, and low precision; thus resulting in poor stability of the ...
