AI Technical Summary
Currently, in the automotive body structure, the B-pillar, sill, floor lower side beam, and roof crossbeam form a ring-shaped force transmission structure. The absence of a B-pillar leads to a decrease in body rigidity, a reduction in collision safety performance, and battery deformation due to compression, hindering the mass production of B-pillar-less vehicles.
A separator is installed between the door and the sill beam to form multiple parallel cavity structures, enhancing the force transmission path. These include a first cavity, a second cavity, and a third cavity. The separator, made of aluminum beam material, enhances the connection between the door and the sill beam, forming an L-shaped, C-shaped, or U-shaped structure to strengthen the force transmission structure.
It improves the side-impact safety of vehicles without B-pillars, enhances the vehicle's resistance to collision deformation, protects battery cells, improves the vehicle's cost, weight, and performance, and meets the requirements of automotive evaluation regulations.
