Description
Technical Field
[0001] The utility model relates to the technical field of automobile seats, in particular to a rear seat backrest structure capable of eliminating armrest gaps. Background Art
[0002] The 4:6 seat is a common rear seat structure used in existing cars. The backrest of the 6-part seat is usually equipped with an armrest assembly that can be flipped forward and opened, and the armrest assembly is usually located between the 6-part seat backrest and the 4-part seat backrest. The armrest assembly usually includes an armrest frame and an armrest body wrapped around the armrest frame. The backrest of the 6-part seat usually includes a backrest frame and backrest foam. At present, due to the relationship between product size, product structure and the accuracy of the installation position, gaps are often easily generated between the backrest foam and the corresponding side panel of the armrest assembly. In particular: Figure 3 and Figure 4 As shown, the armrest frame 1 is generally welded to the backrest frame 3 through the vertical sheet metal 5 at the lower right end. The armrest frame 1 and the vertical sheet metal 5 are rotationally matched, and a Y-direction gap is left between the armrest body 2 and the vertical sheet metal 5. This structural design requires an avoidance installation groove a to be opened on the backrest foam 4 at the position corresponding to the vertical sheet metal 5, which makes the thickness of the backrest foam 4 at this position smaller, and the backrest foam 4 at this position is prone to have a gap with the armrest body 2, which not only affects the appearance, but also makes the frame, sheet metal, etc. easily exposed to cause safety problems. Utility Model Content
[0003] In view of the problems existing in the above-mentioned prior art, the utility model aims to provide a rear seat backrest structure capable of eliminating the gap between the armrests, so as to solve the problem that a gap is easily generated between the backrest foam and the side wall of the armrest body.
[0004] In order to achieve the above-mentioned purpose, the utility model proposes a rear seat backrest structure capable of eliminating the armrest gap, comprising an armrest assembly and a backrest assembly, wherein the armrest assembly comprises an armrest frame and an armrest body covered outside the armrest frame, and the backrest assembly comprises a backrest frame and a backrest foam, wherein the armrest frame is welded to the backrest frame at the lower right end through a vertical sheet metal part, the armrest frame and the vertical sheet metal part are rotatably matched, and a Y-direction gap is left between the armrest body and the vertical sheet metal part, and further comprises a PE sheet, wherein the PE sheet is integrally foamed on the backrest foam, the PE sheet extends up and down and is arranged close to the right side wall of the armrest body, and the PE sheet extends downward to the bottom of the armrest body, so that the Y-direction limit is located between the vertical sheet metal part and the armrest body.
[0005] In the above scheme: the PE sheet is made of polyethylene foam plastic, which has good mechanical properties, is tough, flexible, friction-resistant, has good processing properties, is easy to shape, and is relatively cheap.
[0006] In the above scheme: the backrest foam is covered with a cover, and the cover covers the PE sheet. This design can effectively eliminate the gap between the cover and the corresponding side wall of the armrest body. It should be noted that the backrest foam is preferably covered with the PE sheet.
[0007] In the above scheme: the PE sheet extends upward to the top of the armrest body, and the PE sheet covered with the surface cover is just limited in the Y direction between the vertical sheet metal and the armrest body to avoid the gap being too large to affect the assembly qualification rate.
[0008] In the above scheme: the armrest assembly is equipped with a limit damping block, and the limit damping block is installed on the right end surface of the vertical sheet metal part. Another function of setting the vertical sheet metal part is to provide an installation position for the limit damping block.
[0009] The beneficial effects of the utility model are as follows: 1. By laying out a PE sheet and extending the lower end of the PE sheet to the bottom of the armrest body, the PE sheet is limited in the Y direction between the vertical sheet metal part and the armrest body. When the backrest foam is compressed and shrinks, the PE sheet on the backrest foam will be limited to the right by the vertical sheet metal part, so that the backrest foam will not deform to the right to produce a large gap, which effectively solves the problem of a gap easily generated between the backrest foam and the side wall of the armrest body; 2. After the armrest assembly and the backrest assembly in the traditional structure are assembled, a large gap is easily generated between the two, thereby affecting the assembly qualification rate of the product. The present structure uses a PE sheet to fill the gap between the armrest body and the vertical sheet metal part, which can effectively reduce the assembly error and increase the assembly qualification rate of the product from 30% to more than 95%.
