An aluminum alloy side wall structure and an automobile

Abstract

The invention provides an aluminum alloy side wall structure and an automobile, belonging to the automobile lightweight field. The structure comprises an outer frame upper side beam, an outer frame Acolumn, an outer frame C column, an outer frame lower middle side beam, an outer frame lower front side beam, an outer frame lower rear side beam, an upper cross member, a lower cross member, a middlecross member, a door inclined beam, a plurality of upright columns and an inner plug-in joint. The structure comprises an outer frame upper side beam, an outer frame A column, an outer frame C column, an outer frame lower middle side beam, an outer frame lower front side beam, an outer frame lower rear side beam, a lower middle side beam of the outer frame, a lower front side beam of the outer frame, and a lower rear side beam of the outer frame by mortise and tenon. The top cross member is connected with the A column of the outer frame, and the end intersection of the C column of the outer frame is connected with the tenon and mortise of the plug-in joint. One end of the lower cross member is connected with the door inclined beam by the tenon and mortise joint, and the other end of the lower cross member is connected with the tenon and mortise joint of the C column of the outer frame by the tenon and mortise joint. The front beam under the outer frame is connected with the A column of the outer frame, the A column of the outer frame is connected with the upper beam of the outer frame, the upper beam of the outer frame is connected with the C column of the outer frame, and the C column of the outer frame is connected with the lower rear beam of the outer frame by means of plug-in joints. The automobile include that above structure. The structure and the lightweight effect of the automobile are good.

Description

technical field [0001] The invention relates to the field of lightweight automobiles, in particular to an aluminum alloy side wall structure and an automobile. Background technique [0002] Lightweight has become one of the important development trends of automobiles, especially new energy vehicles. The implementation of lightweight vehicles can effectively reduce vehicle energy consumption and extend the driving range of new energy vehicles. [0003] Aluminum alloy materials are widely used in lightweight body structures due to their low density, high stiffness-to-weight ratio, and abundant material supply. However, several weaknesses of aluminum alloy profiles such as "not easy to bend", "not easy to weld", and "material strength is lower than steel" seriously restrict its application in lightweight car bodies. [0004] At present, the side wall structure is generally made of steel. Even if there is a side wall structure made of aluminum alloy, it cannot be applied in pro...

However, several weaknesses of aluminum alloy profiles such as "not easy to bend", "not easy to weld", and "material strength is lower than steel" seriously restrict its application in lightweight car bodies

[0004] At present, the side wall structure is generally made of steel. Even if there is a side wall structure made of aluminum alloy, it cannot be applied in production and life because of its poor strength and rigidity and difficult welding technology.
