Problems solved by technology

Body-in-white refers to the body assembly that has been welded but not painted. The connecting pillars connecting the roof and the front cabin on the left and right fronts are A-pillars. According to the new industry standard of the Ministry of Transport, before the body-in-white is painted It is necessary to conduct an impact test on the double A-pillars of the cab. Almost all the A-pillars of the body-in-white of existing manufacturers are a cavity structure welded by inner and outer panels, which cannot meet the requirements, and the strength cannot meet the new industry experimental standards. strength requirements

Abstract

The invention discloses a heavy truck column A. The heavy truck column A comprises an outer plate, an inner plate and a lining reinforcing plate, the two side edges of the outer plate and the two side edges of the inner plate are correspondingly connected to form a column body with a cavity, and the lining reinforcing plate is arranged in the column body. According to the heavy truck A column, the two side edges of the outer plate and the two side edges of the inner plate are correspondingly welded to form the cavity structure similar to a cylinder, then the lining reinforcing plate is welded to the interior of the cylindrical cavity structure, and during an impact test, the lining reinforcing plate can absorb energy of impact force and reduce the impact force of the impact force on the A column body; therefore, the column A meets the test strength requirement.

Description

technical field [0001] The invention relates to the technical field of vehicle design and manufacture, in particular to an A-pillar of a heavy truck. Background technique [0002] People pay more and more attention to the safety of heavy-duty truck cabs. Body-in-white refers to the body assembly that has been welded but not painted. The connecting pillars connecting the roof and the front cabin on the left and right fronts are A-pillars. According to the new industry standard of the Ministry of Transport, before the body-in-white is painted It is necessary to conduct an impact test on the double A-pillars of the cab. Almost all the A-pillars of the body-in-white of existing manufacturers are a cavity structure welded by inner and outer panels, which cannot meet the requirements, and the strength cannot meet the new industry experimental standards. strength requirements. [0003] Therefore, how to meet the strength requirements of the body-in-white impact test is a technica...
