This invention discloses a door sill structure for
new energy vehicles, including an outer door
sill plate, an inner door
sill plate, and a door sill aluminum profile disposed between the outer and inner door sill plates. It also includes a door sill partition, which is located between the outer and inner door sill plates and is welded to both. The partition is also riveted to the door sill aluminum profile. This
new energy vehicle door sill structure is rationally designed. The
welding and riveting surfaces of the partition are located at the upper and lower ends of the partition, respectively connecting the inner and outer door sill plates and the inner door sill aluminum profile. When the door sill is subjected to a Z-axis force, the force is transferred to the aluminum profile through the partition. This structure makes the load transfer of the door sill and its internal structure more rational and the
load distribution more uniform, effectively improving the door sill support and load-bearing performance of
new energy vehicles.
