Problems solved by technology
[0003] Aluminum alloy profiles have been widely used in building decoration fields such as doors, windows, and curtain walls. The cross-sectional structure of aluminum alloy building profiles is often based on aesthetics, and the force-bearing form in building decoration is relatively simple.
Considering the complex loading conditions of the car body and the need to absorb energy in a collision, the application of architectural aluminum alloy profile cross-section structures to car bodies has a greater safety hazard

Embodiment Construction
[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.
[0044] like Figure 1-2 As shown, the present invention provides an aluminum alloy profile suitable for load-bearing and energy-absorbing body frame, which includes a peripheral plate 110 whose cross section is a hollow rectangle, and the four borders of the rectangular peripheral plate 110 have the same thickness. The peripheral panel 110 includes an outer contour line outer 111 and an inner contour line 112 which are piecewise linear line segments.
[0045] The first rib 120 is arranged on the inner side of the peripheral plate 110 , and the cross section of the first rib 120 is an inscribed quadrilateral of the peripheral plate 110 . The first rib 120 includes an outer contour line 121 and an inner contour line 122, both of which are segmented linear line segments. Both ...

The invention discloses an aluminium alloy profile suitable for bearing and energy absorption of a vehicle body framework. The aluminium alloy profile suitable for bearing and energy absorption of thevehicle body framework comprises a peripheral plate, a first rib plate and a second rib plate, wherein the cross section of the peripheral plate is in a shape of a hollow rectangle; four frames of the rectangle have same thicknesses; the first rib plate is arranged on the internal side of the peripheral plate; the cross section of the first rib plate is an inscribed quadrangle of the peripheral plate; the second rib plate is arranged on the internal side of the first rib plate; and the cross section of the second rib plate is an inscribed quadrangle of the first rib plate. The aluminium alloyprofile suitable for bearing and energy absorption of the vehicle body framework has the advantages of good non-deformability, better energy absorbing characteristic, high bearing capacity and lighter mass.
Description
technical field [0001] The invention belongs to the technical field of vehicle body frame load-bearing profiles, in particular to an aluminum alloy profile suitable for vehicle body frame load-bearing and energy-absorbing. Background technique [0002] The popularity of automobiles has brought about problems such as energy crisis and environmental pollution. Under the industrial development theme of "energy saving, safety, and environmental protection", the development of new energy vehicles has become a development trend. For new energy vehicles with a new architecture, lightweight materials make them develop towards higher performance. As the largest part of a car, the body weight accounts for about 30%-40% of the whole vehicle. Light weight of the body can increase the battery life of new energy vehicles by reducing weight, reduce battery costs, and obtain better economic benefits. In the application of new materials to reduce the weight of the car body, aluminum alloy h...
