Abstract
The utility model discloses a car body longitudinal beam local reinforcing structure. The car body longitudinal beam local reinforcing structure comprises a car body longitudinal beam, and further comprises a lower liner plate and an upper liner plate, wherein the section of the car body longitudinal beam is U-type, two long edges of the lower liner plate are welded on two sides of a U-type groove bottom of the car body longitudinal beam respectively, and two long edges of the upper liner plate are welded on two sides of a U-type groove opening of the car body longitudinal beam respectively. A frame-shaped sealed structure is formed by transverse reinforcing ribs or transverse reinforcing protrusions or longitudinally concave-convex and up-and-down shapes of different members, and accordingly requirements for strength reinforcing are met. Even transition of the car body longitudinal beam local reinforcing structure and the original structure is achieved through changes of the height and the size of lateral wings of the lower liner plate. Meanwhile, because the car body longitudinal beam local reinforcing structure is completely formed in a sheet metal stamping and welding mode, and groove-type steel materials and even press forging piece structures are prevented from being adopted, the weight of the car body longitudinal beam local reinforcing structure is reduced, and the car body longitudinal beam local reinforcing structure is simple in structure and very practical.

The specific embodiment
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is further described.
Embodiment
Shown in Fig. 1～9, Fig. 1 is structural representation of the present utility model; Fig. 2 is the structural representation of chassis runner; Fig. 3 is the structural representation of following liner plate; Fig. 4 is the structural representation of going up liner plate; Fig. 5 is the structural representation of brace panel; Fig. 6 is the structural representation of the utility model cross-sectional plane; Fig. 7 is the birds-eye view of following liner plate; Fig. 8 is the cross sectional view of following liner plate; Fig. 9 is the cross sectional view that goes up liner plate.
The local structure of strengthening of a kind of motorcar body longeron, comprise that the cross section is U-shaped chassis runner 1, the local structure of strengthening of a kind of motorcar body longeron, also comprise following liner plate 2, go up liner plate 3, two long limits of following liner plate 2 are welded on the U-shaped bottom land both sides of chassis runner 1 respectively, two long limits of last liner plate 3 are welded on the U-shaped notch both sides of chassis runner respectively, and making the cross-sectional plane of the part reinforcement structure of chassis runner is the shaped as frame enclosed construction.
The local structure of strengthening of a kind of motorcar body longeron, also comprise brace panel 4, last liner plate 3 arranges projection 31 towards the direction of notch, and brace panel 4 is welded on the projection 31, make liner plate 3 bottom transverse sections be " protruding " shape, the flank face of last liner plate 3 is continuous concavo-convex alternate shape.
The utility model preferred embodiment in, circular hole plug 41 is set on the brace panel 4, brace panel 4 and projection 31 are connected together by the circular hole plug welding.
The center in the U-shaped cross section of following liner plate 2 corresponding chassis runneies 1 arranges protrudes reinforced rib 21, makes down the side of liner plate simultaneously be continuous concavo-convex alternate shape, and the height of following liner plate 2 flank faces reduces gradually along automobile longitudinal.
