[0003] With the continuous development of new energy vehicles, in order to meet the higher battery life of the car, the lightweight design of the body structure has gradually become a trend. Among them, the aluminum-magnesium alloy die-casting parts have the advantages of light weight, high integration, flexible structural design, and high local strength. , are more and more applied to the body structure. At present, the lower part of the A-pillar of a traditional car is mostly composed of multiple sheet metal stamping parts such as the A-pillar lower inner panel body, the A-pillar lower reinforcement plate and the connecting plate. This kind of structural design has many parts, heavy weight, complicated welding process, and single structural design, which is very inconsistent with the trend of body structure a

The invention discloses an automobile A-pillar lower die casting structure which comprises an A-pillar lower die casting body device for reducing the weight of an A-pillar lower die casting, and a connecting device used for installing the A-pillar lower die casting. According to the automobile A-pillar lower die casting structure, the A-pillar lower die casting formed by a plurality of parts is made into a whole through the A-pillar lower die casting body device, the connecting steps are reduced, light weight is achieved, reinforcing ribs are arranged in the A-pillar lower die casting body device, and the strength is improved. Glue riveting connection is adopted at multiple positions, original welding procedures are reduced, the automobile body side outer plate and the automobile body threshold beam facilitate installation of a die casting on the lower portion of an automobile A column, the automobile body threshold beam and the automobile body threshold beam are connected conveniently through the inserting blocks, and aluminum alloy or magnesium alloy materials are light in weight, high in strength and accordant with the light weight trend. And the staggered reinforcing ribs improve the strength of the die casting at the lower part of the automobile A column.
Description
technical field [0001] The invention relates to the technical field of lightweight automobile bodies, in particular to a die-casting structure for the lower part of an automobile A-pillar. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels and new vehicle power devices), and the comprehensive vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. [0003] With the continuous development of new energy vehicles, in order to meet the higher battery life of the car, the lightweight design of the body structure has gradually become a trend. Among them, the aluminum-magnesium alloy die-casting parts have the advantages of light weight, high integration, flexible structural design, and high local strength. , are more and more applied to the body structure. At present, th...
