Detailed Description
The aluminum alloy sill beam assembly structure of the present invention will be further described below with reference to specific embodiments to help those skilled in the art understand the technical solution of the present invention more completely, accurately and deeply.
Example 1
As shown in fig. 3-5, the aluminum alloy threshold beam assembly structure of this embodiment includes aluminum alloy threshold beam 10, side wall planking overlap edge 20 and floor overlap edge 30, aluminum alloy threshold beam 10 includes aluminum alloy threshold beam body 11, have a plurality of horizontal muscle 12 and a plurality of vertical muscle 13 in the aluminum alloy threshold beam body 11, a plurality of horizontal muscle 12 and a plurality of vertical muscle 13 crisscross a plurality of little die cavities of formation. The upper surface of aluminum alloy threshold roof beam body 11 is provided with vertical face 16 along length direction, the side surface of aluminum alloy threshold roof beam body 11 is provided with horizontal face 15 along length direction, the lower surface of aluminum alloy threshold roof beam body 11 still is provided with down vertical face 17 along length direction. One end of the side wall outer panel overlap edge 20 is welded and fixed to the upper vertical surface 16, and the other end of the side wall outer panel overlap edge 20 is connected to the side wall of the aluminum alloy doorsill beam body 11 by a self-tapping screw (FDS connection). The floor panel 40 is disposed on the lateral surface 15, and the floor overlap 30 is disposed between the floor panel 40 and the upper surface of the aluminum alloy rocker beam body 11, and the lateral surface 15, the floor panel 40, and the floor overlap 30 are connected by clinch rivets (SPR connection).
This embodiment will disperse steel stamping workpiece and assemble into an aluminum alloy section bar spare, forms whole cavity structure, has both reduced part quantity and has reduced purchasing cost expense to increased threshold structure's bulk strength, the total weight has also reduced, accords with the lightweight design theory of car. This embodiment has been tried on the volume production motorcycle type and is used, and this structural design adopts aluminium alloy ex-trusions cavity structures, and not only weight is lighter, and the structure is compacter, and under the same circumstances, intensity is higher, subtracts the lightweight of car when heavy at new energy automobile trade, has reduced frock clamp's development, changes the spot welding into FDS, SPR cold-linked, has not only reduced development cost, has also improved the assembly precision of whole car.
