Abstract

The invention discloses a threshold supporting plate capable of improving side impact performance, and relates to the field of automobiles. The threshold supporting plate comprises an automobile floor, wherein the edge of the automobile floor is provided with a threshold inner plate; after the threshold inner plate is welded with the automobile floor, and a seat front cross beam and a seat rear cross beam on the automobile floor, the threshold inner plate is welded with a threshold outer plate; a first U-shaped supporting plate and a second U-shaped supporting plate are arranged in a thresholdcavity formed by the threshold inner plate and the threshold outer plate; the first supporting plate is welded to the threshold outer plate, and the second supporting plate is welded to the thresholdinner plate; the first supporting plate and the second supporting plate both carry out centring with the seat front cross beam and the seat rear cross beam; the first supporting plate and the secondsupporting plate are subjected to centring to form a back-to-back structure form; and the center of the first supporting plate and the center of the second supporting plate are independently providedwith a gap for inserting a B pillar inner plate. By use of the threshold supporting plate, the problems that an existing supporting plate structure is complex, is too heavy and can not be universal orcertain supporting structures are too small and can not meet a five-star requirement in a C-NCAP (China-New Car Assessment Program) impact.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a door sill support plate for improving the side impact performance of automobiles. Background technique [0002] Side impact is a collision detection item stipulated in the mandatory regulations of the national "GB20071 Side Impact Occupant Protection", and it is also a collision item of the industry's star collision C-NCAP. The conventional threshold structure can meet the national mandatory regulations, but to meet the five-star requirements in the C-NCAP collision, it is often necessary to design a more practical structure. In the past, there were many types of sill connections. Some braces had complex structures and were too heavy, while others were too small to meet the five-star requirements. Combined with CAE analysis, the present invention develops a brand-new door sill support plate structure, which can realize the common use of parts, reduce the weigh...
