Background
In the life of people, automobiles become necessary traveling tools, different use demands are needed for adjusting the seats in use of automobile seats, the adjustment of the height of the seats is realized through a seat lifting mechanism, and the seat lifting mechanism is correspondingly matched with the cushion frame in structure.
At present, a traditional automobile seat lifting structure, such as an automobile seat lifting mechanism with a Chinese patent publication number of CN201065081Y, comprises a side plate, front and rear lifting pipes and a connecting rod, wherein the lifting pipes are directly hinged with the side plate, the connecting rod is provided with a hole for the lifting pipes to pass through, and is fixed on the lifting pipes in a welding mode, and a certain interval is reserved between the connecting rod and the side plate.
However, the inventor considers that the torsion of the support is concentrated on the lifting pipe, the rigidity requirement on the lifting pipe is high, and the gap between the connecting rod and the side plate is too large, so that the layout of the seat lifting structure is relatively limited, and the rationality of the layout is also high.
In another example, CN206812835U is a front link structure of a car seat frame, which includes a seat frame side plate, a link, and a transverse tube, in which the end of the link is hinged to the seat frame side plate, and the transverse tube is hinged to the middle of the link.
Although the seat frame side plate is not directly hinged with the transverse tube, the inventor believes that after the middle part of the connecting rod is hinged with the transverse tube, the lifted torsion is concentrated at the positions where the transverse tube is hinged with the seat frame side plate and the connecting rod, but the torsion born by the transverse tube is not shared too much by the connecting rod, meanwhile, when the transverse tube is welded with the connecting rod, the end of the transverse tube cannot be directly welded with the connecting rod, and the stability of welding can be realized only after the transverse tube passes through a part of the connecting rod, so that the gap between the connecting rod and the seat frame side plate is still large, the layout of the seat lifting structure is relatively limited, and the rationality of the layout is also required to be higher.
And as another example, the zero gravity seat frame adjusting structure with the Chinese patent publication number of CN113147532A comprises a frame side plate, an adjusting connecting rod and a cross rod, wherein the frame side plate is directly hinged with the cross rod, one end of the adjusting connecting rod opposite to the cross rod is provided with a semicircular groove, and the cross rod is welded on the connecting rod through the semicircular groove.
However, the inventor believes that the structure still has the torsion force born by the cross rod to be larger, and the torsion force born by the connecting part of the cross rod and the connecting part of the cross rod to be larger, so that the welding technology and requirements on the connecting rod and the cross rod are more severe.
In summary, with respect to the above prior art solutions, the inventor considers that there is an excessive requirement for rigidity of the anti-submarine pipe itself, and that the gap between the connecting rod and the side plate is too large, resulting in correspondingly high requirements for matching layout of the lifting mechanism, which clearly increases manufacturing cost and manufacturing difficulty.
