In the aluminum alloy seat backrest structure, if the backrest hinge structure adopts a stamping part, the forming is difficult due to the complex shape, the strength is difficult to meet the requirements, and the connection problem also exists between the nut and the aluminum alloy part.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a connection structure to solve the connection process problem between high, the difficult, the aluminum alloy seat back hinged joint board shaping of aluminum alloy seat back hinged joint board intensity requirement, aluminum alloy hinged joint board and the nut.
The technical scheme of the utility model provides an aluminum alloy back row seat back hinge structure, it includes aluminium system back longitudinal pipe roof beam, connecting plate up end, steel rivet pressing nut, aluminium system back horizontal pipe roof beam, connecting plate crossbeam mating holes, connecting plate nut mating holes, aluminium system back hinge connecting plate, its characterized in that;
the steel pressure riveting nut is pressed and riveted on the aluminum backrest hinge connecting plate through a connecting plate nut matching hole, is provided with threads, and is matched with the steel pressure riveting nut through a fixing bolt to connect the seat backrest with the seat cushion framework;
the aluminum backrest hinge connecting plate is sleeved in the aluminum backrest transverse tubular beam through the connecting plate transverse beam matching hole and fixedly connected with the aluminum backrest transverse tubular beam in a welding mode, and meanwhile, the aluminum backrest hinge connecting plate is fixedly connected with the aluminum backrest longitudinal tubular beam through the upper end face of the connecting plate in a welding mode.
Furthermore, the aluminum backrest hinge connecting plate is an extrusion forming component, and hollow structures are adopted at multiple positions.
Further, the nut matching hole of the connecting plate is a special-shaped hole.
The utility model has the advantages that:
(1) the hinge connecting plate for the aluminum alloy seat backrest adopts an extrusion forming process, is simple and reliable in process, high in production efficiency and greatly reduced in manufacturing cost, and can well meet the relevant strength requirements of the automobile seat.
(2) The strength requirement can be well met through the cross section optimization design;
(3) the production efficiency of parts is high, and the manufacturing cost is greatly reduced;
(4) the mode of riveting the nut is adopted, and the connection problem between steel and aluminum mixing is solved.

Detailed Description
The technical solution of the present invention is further explained in detail with reference to fig. 2-4.
As shown in fig. 2 to 4, the aluminum alloy rear seat back hinge structure according to the embodiment includes: the structure comprises an aluminum backrest longitudinal tubular beam 4, a connecting plate upper end face 5, threads 6, a steel rivet pressing nut 7, an aluminum backrest transverse tubular beam 8, a connecting plate cross beam matching hole 9, a connecting plate nut matching hole 10 and an aluminum backrest hinge connecting plate 11.
The aluminum backrest hinge connecting plate 11 is an extrusion-molded component, hollow-out design is adopted at multiple positions, and the strength of parts can be well guaranteed while a good weight reduction effect is achieved.
The steel pressure riveting nut 7 is a special part and is pressure riveted on the aluminum backrest hinge connecting plate 11 through the connecting plate nut matching hole 10, and the connecting plate nut matching hole 10 is designed to be a special-shaped hole so as to prevent the steel pressure riveting nut 7 and the aluminum backrest hinge connecting plate 11 from rotating in the using process. The steel pressure riveting nut 7 is provided with threads 6, and the seat backrest and the seat cushion framework can be connected together through the matching of the fixing bolt and the steel pressure riveting nut 7.
The aluminum backrest hinged connection plate 11 is sleeved in the aluminum backrest transverse tubular beam 8 through the connection plate cross beam matching hole 9 and then fixedly connected with the aluminum backrest transverse tubular beam 8 through circumferential welding, and meanwhile, the aluminum backrest hinged connection plate 11 is fixedly connected with the aluminum backrest longitudinal tubular beam 4 through the connection plate upper end surface 5 in a welding mode.
While the principles of the invention have been described in detail in connection with the preferred embodiments thereof, it will be understood by those skilled in the art that the above-described embodiments are merely illustrative of exemplary implementations of the invention and are not limiting of the scope of the invention.
