Abstract
The utility model relates to a reinforcement for a door sill beam of an automobile. The reinforcement comprises a U-shaped transversal reinforcement and a longitudinal reinforcement; outwardly turned-over edges are arranged at two ends of the transversal reinforcement and the longitudinal reinforcement; reinforced ribs are arranged on the two sides of the longitudinal reinforcement and on one side of the transversal reinforcement; and the bottom of the transversal reinforcement and the bottom of the longitudinal reinforcement are, mutually overlapped in a crisscrossed manner and welded integrally. The reinforcement for the door sill beam is used to be welded with the door sill beam in an automobile door sill structure, and can improve the sidewise impact resistance of the automobile.
Description
Technical field
The utility model relates to the parts of automobile, particularly the automobile door sill beam reinforcement that welds mutually with the automobile door sill beam.
Background technology
At present, the structure of automobile door sill Liang Chu substantially all is made up of floor skirt beam, sill strip and side-wall outer-plate three parts, because the restriction that cost, weight and technology are made, these three sheet metal component structure designs are single, and can not adopt the high-intensity material of heavy gauge, cause sill strip impact resistant capability in side collision very weak, the impact resistant capability of therefore strengthening sill strip becomes one of important measures that improve the automotive side face collision safety performance.
The utility model content
The purpose of this utility model provides a kind of automobile door sill beam reinforcement simple in structure, uses it in the automobile door sill structure and welds with sill strip, to improve the side direction impact resistant capability of automobile.
Automobile door sill beam reinforcement described in the utility model, form by the horizontal reinforcement and the longitudinal reinforcer that are the U type, two ends at horizontal reinforcement and longitudinal reinforcer are provided with outside flange, one side of the both sides of longitudinal reinforcer and horizontal reinforcement is provided with reinforced rib, and it is overlapped integrally welded that the bottom of horizontal reinforcement and the bottom of longitudinal reinforcer are right-angled crossing.
Two these sill strip reinforcements are welded on automobile door sill beam inboard by its flange, and these two sill strip reinforcements lay respectively on the sill strip of car body central post and front-row seats corresponding position, can improve the side direction impact resistant capability of automobile.
Automobile door sill beam reinforcement described in the utility model only is made up of the horizontal reinforcement and the longitudinal reinforcer that are the U type, so simple in structure; Because laterally, longitudinal reinforcer welding back is a box-like structure, so its strength character is good, after welding, be the osed top crash feature with the automobile door sill beam, this structure has the very strong effect that prevents the threshold distortion in automobile side crash, so can improve the broadside impact performance of automobile largely, thereby also can reduce requirement largely, with the manufacturing cost of lowering the threshold to the sill strip material property.Because the structure and the manufacturing process of this sill strip reinforcement are simple, so aspect material selection, can select the high tensile steel plate that adopts the above thickness of 2mm for use, thereby can further increase the intensity of sill strip reinforcement, increase the intensity of automobile door sill then, improve the side direction impact resistant capability of automobile.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is the schematic perspective view of automobile door sill beam reinforcement described in the utility model;
Fig. 2 is welded on view on the automobile door sill beam for this sill strip reinforcement, and this figure is the cross sectional drawing of the sill strip seen to tailstock direction from headstock.
The specific embodiment
As shown in Figure 1, this automobile door sill beam reinforcement is made up of horizontal reinforcement 1 that is the U type and longitudinal reinforcer 4, two ends at horizontal reinforcement 1 and longitudinal reinforcer 4 are provided with outside flange 2, one side of the both sides of longitudinal reinforcer 4 and horizontal reinforcement 1 is provided with reinforced rib 3, and it is overlapped integrally welded that the bottom of horizontal reinforcement 1 and the bottom of longitudinal reinforcer 4 are right-angled crossing.
As shown in Figure 2, two these sill strip reinforcements are welded on automobile door sill beam 5 inboards by its flange 2, these two sill strip reinforcements lay respectively on the sill strip 5 of car body central post and front-row seats corresponding position, to improve the side direction impact resistant capability of automobile.
