The present invention will be further described with reference to the following examples and drawings, and the following embodiments are examples for illustrating the present invention, but the present invention is not limited to the embodiments.
As shown in fig. 1, a general angle adjuster mounting structure includes a backrest side plate 1, a lower angle adjuster connecting plate 2 and an angle adjuster 3, the lower angle adjuster connecting plate 2 is connected to a lower end of the backrest side plate 1 through the angle adjuster 3, the backrest side plate 1 serves as a lateral support member of a seat backrest, the lower angle adjuster connecting plate 2 is connected to a seat frame framework and receives the angle adjuster 3, two sides of the angle adjuster 3 are respectively welded and fixed to the backrest side plate 1 and the lower angle adjuster connecting plate 2, and angle adjustment of the seat backrest is achieved through the structure.
Fig. 2 shows a construction of a recliner 3, which, like other recliners, has an overall disc-like configuration, and a welding surface 31 is formed on a side facing the back edge plate 1, and a plurality of studs 32 are distributed in the welding surface 31, and the plurality of studs 32 are distributed in an annular array along the circumferential direction of the welding surface 31, and teeth 33 are provided on the circumferential edge of the welding surface 31.
Referring to fig. 3, the lower connecting plate 2 of the angle adjuster is provided with an angle adjuster hole 21, one side of the angle adjuster 3 is positioned in the angle adjuster hole 21, and two sides below the angle adjuster hole 21 are respectively provided with a first positioning hole 22 with a relatively small aperture, which is used for positioning on a corresponding tool during welding. The two first positioning holes 22 and the angle adjuster holes 21 have a specific center distance, so that the same relative positions of the two first positioning holes 22 on the lower connecting plate 2 of the angle adjuster with different specifications are set to be the same, the same welding tool can be adopted when different seat frameworks are welded, the universality of equipment is improved, and the lower connecting plate 2 of the angle adjuster is further provided with a first positioning plane 23 for further ensuring the positioning effect.
Fig. 4 is a schematic view of a partial structure of the lower end of the backrest side plate 1, and it can be seen that the lower end of the backrest side plate 1 is provided with an angle adjuster mounting hole 4, the angle adjuster mounting hole 4 is substantially in a circular hole structure, a plurality of arc notches 4a extending radially outward from the edge of the angle adjuster mounting hole are circumferentially distributed, and the arc notches 4a are centrally and symmetrically distributed by taking the center of the circle of the angle adjuster mounting hole 4 as the center. Welding edges 41 are formed between the adjacent arc notches 4a, the welding edges 41 and the arc notches 4a jointly enclose the inner side edges of the angle adjuster mounting holes 4, the arc notches 4a are semi-circular arcs, the structures of the welding edges 41 are consistent, the arc structures are arc structures with the centers of the angle adjuster mounting holes 4 as the circle centers, and the arc notches 4a are closer to the inner sides of the angle adjuster mounting holes 4.
