Embodiment one
As depicted in figs. 1 and 2, seat mounting bracket provided in this embodiment includes first crossbeam 1, second cross beam 2, first Stringer 3 and the second stringer 4.First stringer 3 and the setting of the second stringer 4 interval, for being fixed to underbody.First crossbeam 1 and second cross beam 2 be also spaced setting, and the equal one end of the two is adhered on the upper surface of the first stringer 3, and the other end is adhered to second On the upper surface of stringer 4.First crossbeam 1, second cross beam 2, the first stringer 3 and the second stringer 4 are aluminium alloy extrusions.
First crossbeam 1, second cross beam 2, the first stringer 3 and the second stringer 4 are aluminium alloy extrusions, are guaranteeing that structure is strong While spending, mold investment is also relatively low.To be Nian Jie between crossbeam and stringer, it can either guarantee the intensity connected, and without hot shadow Ring area.
Specifically, aluminium alloy extrusions internal grain more it is thin thus possess better rigidity and intensity, disruption properties are also more preferable. In addition, aluminium alloy extrusions is also easy to extrusion forming, is easy to produce in enormous quantities, price is relatively low.For the seat of high sitting posture vehicle Mounting bracket, its intensity of seat mounting bracket and rigidity that punching press aluminium sheet is formed are unable to satisfy design requirement, and aluminium alloy type Material seat mounting bracket but can satisfy requirement.First crossbeam 1, second cross beam 2, the first stringer 3 and the second stringer 4 are aluminium Alloy profile, its die cost of seat mounting bracket compared to part punching forming are reduced at hundred times, and production efficiency is also higher. Such as: part by the stamping seat mounting bracket die cost of aluminium alloy plate substantially between 1,000,000-200 ten thousand, but Aluminium alloy extrusions seat mounting bracket die cost only has 10,000-4 ten thousand.
Further, the first stringer 3 can be with the second stringer 4 and be arranged in parallel, and first crossbeam 1 and second cross beam 2 can also To be to be arranged in parallel, automotive seat is installed on two crossbeams.
