Abstract
The utility model provides a closed reinforcing beam frame of the rear floor board of a saloon car, which includes a left reinforcing beam and a right reinforcing beam parallel to each other. A front crossbeam is connected on the front end of the left reinforcing beam and the right reinforcing beam, an apron plate reinforcing beam is connected on the rear end; the four components are connected into a closed ring. The left reinforcing beam, the right reinforcing beam, and the front crossbeam are all welded with the rear floor board, a horizontal energy absorbing groove is arranged on the rear section of the left reinforcing beam and the right reinforcing beam. The utility model provides the closed reinforcing beam structure, besides the rear apron plate reinforcing beam, all other components directly overlap the rear floor board, not only the strength of the rear floor board is well improved, but also great contribution is done for improving the torsional rigidity of the whole vehicle. As for improving the rear collision property of the whole vehicle, the vertical reinforcing beam absorbs energy, the horizontal beam inhibits deformation, and then the deformation is prevented from diffusing to the passenger compartment, and the energy absorbing effect can be improved.
Description
Technical field
The utility model belongs to the automotive body structure technical field.
Background technology
The back floor bearer of general car is an Open architecture as shown in Figure 1, promptly constitute with the crossbeam B that is connected two longerons from the centre by the parallel longeron A in both sides, this structure is because the not sealing of its longeron two ends, poor stability, cause the car load torsional stiffness poor, bump poor performance behind the car load, the safety of automobile is not high.
Summary of the invention
The objective of the invention is to propose the closed reinforcement roof beam structure in floor behind a kind of car, strengthen the stability and the car load torsional stiffness of car bottom beam, bump performance after improving car load simultaneously.
The technical solution of the utility model is as follows:
The closed reinforcement roof beam structure in floor includes parallel left strength beam and right strength beam behind this car, floor front cross rail after the front end of left strength beam and right strength beam is connected with, and the rear end is connected with back skirtboard strength beam, connects into a closed-loop by these four parts.Left side strength beam, right strength beam and front cross rail all weld with the floor, back.
Further, the back segment at left strength beam and right strength beam is provided with horizontal energy-absorbing groove.
The utility model structure is an osed top strength beam structure, outside the skirtboard strength beam of back, other all parts all directly overlap with the floor, back, not only can improve the intensity on floor, back well, because it is an osed top structure, the torsional stiffness that improves car load also there is very big contribution simultaneously.After improving car load, bump aspect of performance, left and right sides strength beam absorbs energy longitudinally, and horizontal back floor front cross rail and back skirtboard strength beam can suppress distortion, prevents to be out of shape and spreads to passenger cabin, and vertically on the strength beam of the left and right sides endergonic structure is arranged all, further improve energy-absorbing effect.
Description of drawings

Fig. 2: the structural representation of the closed reinforcement roof beam structure in floor behind the car that the utility model proposes;
Fig. 3: the connection location graph of a relation on this closed reinforcement roof beam structure and floor, back;
The specific embodiment
As shown in Figure 2, the closed reinforcement roof beam structure in floor is made up of floor, back front cross rail 1, left strength beam 2, right strength beam 3, back skirtboard strength beam 4 behind the car.Left side strength beam 2 and right strength beam 3 be arranged in parallel, and back floor front cross rail 1 overlaps with the front end of left strength beam 2 and right strength beam 3, and back skirtboard strength beam 4 overlaps with the rear end of left strength beam 2 and right strength beam 3, forms an osed top strength beam shelf structure.The back segment of left side strength beam and right strength beam is provided with horizontal energy-absorbing groove 5.
In concrete production fitting process, being earlier will floor, back front cross rail 1, the mode of left strength beam 2 and right strength beam 3 Fig. 2 overlaps the back and welds with floor 6, back, as shown in Figure 3,4 of back skirtboard strength beams and back skirtboard 7 and left strength beam 2, right strength beam 3 form three layers of weldering.
