Aluminum alloy section mortise-tenon joint structure reinforced based on chemical coupling agent

Abstract

The invention discloses an aluminum alloy section mortise-tenon joint structure reinforced based on a chemical coupling agent. The aluminum alloy section mortise-tenon joint structure reinforced basedon the chemical coupling agent comprises a tenon body and a mortise body, wherein a tenon is integrally formed on one side of the tenon body; a mortise is arranged on one side of the mortise body; and the tenon body and the mortise body are made of aluminum alloy materials and are integrally formed. The aluminum alloy section mortise-tenon joint structure reinforced based on the chemical couplingagent comprises an outer frame, a horizontal support plate and a vertical support plate, wherein the vertical support plate is perpendicular to the horizontal support plate; the vertical support plate, the outer frame and the horizontal support plate form a cross section with the structure in the shape of a Chinese character 'tian'; the tenon and the mortise are arranged correspondingly; the tenon is clamped in the mortise; and the tenon and the mortise are adhered and fixed through the chemical coupling agent.

Description

technical field [0001] The invention belongs to the technical field of connection of aluminum alloy profiles for vehicle bodies, and in particular relates to a mortise and tenon structure of aluminum alloy profiles reinforced by a chemical connecting agent. Background technique [0002] "Energy saving, safety, and environmental protection" is the development theme of modern industry, and new energy vehicles have become an inevitable trend of development. In order to reduce energy consumption and improve performance of new energy vehicles, the lightweight design of the body bears the brunt. New materials subvert the traditional steel body. Aluminum alloy materials have been widely used in new energy vehicles due to their advantages such as high specific strength and strong plasticity. [0003] Aluminum alloy profiles can be used to carry the body frame. At present, the connection methods of aluminum alloy profiles mainly include mechanical fixation such as welding, riveting ...

AI Technical Summary

Problems solved by technology

The thermal conductivity of aluminum alloy is high, and heating will destroy the properties of aluminum alloy material. Defects are likely to exist in the weld and the quality will increase slightly; mechanical connections have large defects, low strength and obvious increase in quality; The adhesive used connects the surface through adhesion and cohesion, which comes from the force between molecules, and its connection performance needs to be verified
