Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Vehicle body rear part structure has been shown in Fig. 1, and the left and right sides in the spare tyre pond 2 on rear floor 1 is provided with left longeron 3 and right vertical beam 4 respectively, and left longeron 3 and right vertical beam 4 are roughly symmetrical structure, and the present embodiment take left longeron 3 as the object described in detail.Shown in composition graphs 1, a kind of hardware and software platform longitudinal beam of rear floor slab of automobile structure of the present utility model, the rear portion of this rear longitudinal floor beam is provided with the curve 61 and prismatic flat part 62 of walking around spare tyre pond, rear floor, and flat part 62 is positioned at the rear of curve.The rear portion of this rear longitudinal floor beam is provided with prismatic flat part 62, the rear overhang length variations of platform vehicle type can be adapted to, when the rear overhang length of vehicle changes, by the flat part 62 at longitudinal floor beam rear portion after brachymemma can keep longeron body construction and cross section constant, original rear floor longitudinal beam structure can be continued to use, and then shorten time-to-market and reduce automobile development cost.
The longeron that the rear longitudinal floor beam of the present embodiment can be structure as a whole or be split type longeron, is described in detail the technical solution of the utility model for split type girder work below.
Shown in composition graphs 1 and Fig. 2, the rear longitudinal floor beam of the present embodiment comprises longitudinal beam front section 5 and longeron back segment 6, and the front portion of longeron back segment 6 is connected with the rear portion of longitudinal beam front section 5.The middle part of longeron back segment 6 is for walking around the curve 61 in spare tyre pond, rear floor 2, and this curve 61 is the spare tyre operatings needs in order to meet different model size, ensures the safety gap in longeron back segment 6 and spare tyre pond, rear floor 2.
When auto-body assembly, the rear portion of longeron back segment 6 and rear longitudinal floor beam fagging 7 and rear end panel 8 are welded to connect.The rear portion of the longeron back segment 6 of the present embodiment is prismatic flat part 62, as shown in Figure 2, the length of this flat part 62 is set to L, this length L is within the rear overhang variation range of successive stage vehicle, by the flat part 62 of this longeron back segment of brachymemma, with keep longeron overall structure and cross section constant, continue to use this rear longitudinal floor beam rear section structure, longeron is made to meet the rear overhang change of successive stage vehicle, thus save mould, fixture etc. and design and develop cost, shorten product development, replacement cycle, cost declines to a great extent.
The middle part of the longeron back segment 6 of the present embodiment is prismatic curve 61, and arranging prismatic curve 61 is continuities in order to touch energy transferring after ensureing automobile.
As shown in Figure 3, the cross section of the longeron back segment 6 of the present embodiment is inverted U-shaped, both sides bottom it are respectively equipped with the flange 63 be connected on rear floor, the cross section entirety of longeron back segment 6 is made to be " several " font, the flange 63 of longeron back segment 6 is connected on rear floor 1, thus between longeron back segment 6 and rear floor 1, form overall closed cavity structure, the intensity of longeron can be improved.
