The backrest frame 100 and the cushion frame 200 are formed by injection molding through metal inserts B, and the backrest main body part 110 and the cushion main body part 210 are both made of light composite material a frames. And metal inserts B are embedded in key strength areas and core part connecting areas selected from the backrest framework 100 and the seat cushion framework 200 respectively. The exposed metal surface is designed in the welding area of the core piece, and the light composite material A is not coated, so that the welding of the core piece area is facilitated, the core piece connection problem is solved, and the increase of the number of parts caused by the thread connection of the sub-pieces is reduced. In addition, when the size or the configuration of the seat is changed, the structures of the backrest main body part 110 and the cushion main body part 210 can be kept unchanged, and the bandwidth of the seat can be adapted by replacing the metal insert B or the angle adjuster connecting piece 300, so that the modularization sharing among the parts is realized.
Example 2:
the present embodiment provides a manufacturing method of a seat frame in embodiment 1, as shown in fig. 13 and fig. 1 to 12 in embodiment 1, the manufacturing method including the steps of:
s1, forming a backrest main body part 110 and a cushion main body part 210 by a light composite material A in an injection molding mode;
s2, the backrest connecting part 120 and the cushion connecting part 220 are made of weldable materials according to the structure of the connecting ends of the backrest main body part 110 and the cushion main body part 210;
s3, the backrest main body part 110 and the backrest connecting part 120 are integrated by injection molding to form a backrest framework 100; the cushion main body part 210 and the cushion connecting part 220 are integrated by injection molding to form a cushion framework 200;
and S4, welding the backrest frame 100 and the cushion frame 200 into a whole through a connector 300 to form the seat frame.
Specifically, the backrest main body portion 110 and the cushion main body portion 210 are both made of a lightweight composite material a, and the backrest connecting portion 120 and the cushion connecting portion 220 are made of a weldable material; the backrest main body part 110 and the backrest connection part 120 are injection molded as one body to form the backrest frame 100; the cushion main body portion 210 and the cushion connecting portion 220 are injection-molded as one body to form the cushion frame 200. The backrest frame 100 and the seat cushion frame 200 manufactured by the method can make the seat frame in the embodiment have the advantages of simple structure, low manufacturing difficulty and high modularization degree.
It is to be understood that the lightweight composite material a in this example is similar to the lightweight composite material a in example 1, and this example is not explained much.
Example 3:
the present embodiment provides a seat assembly comprising a seat cushion and a seatback, the seat assembly further comprising the seat frame of embodiment 1; in this case, as shown in fig. 1 to 12 of embodiment 1, the seat cushion is attached to the seat cushion frame 200, and the backrest is attached to the backrest frame 100.
Specifically, because the seat frame in embodiment 1 has simple structure, the low and high advantage of modularization degree of the manufacturing degree of difficulty, the seat assembly in this embodiment adopts the seat frame of embodiment 1, can further simplify the structure of seat assembly, reduces the manufacturing degree of difficulty of seat assembly and improves the modularization degree of seat assembly.
