Technical Field
[0001] The utility model relates to the technical field of automobile seats, in particular to a high-strength automobile armrest structure. Background Art
[0002] To improve car seat comfort, some models incorporate a center armrest in the rear seats. Typically, these are retractable, stowed away in the backrest when not in use. When needed, they can be folded flat using a flip mechanism. Traditional center armrests have a weak structural strength, typically consisting of a U-shaped sheet metal frame that is simply clipped onto the outer shell. This results in poor assembly stability and can easily cause friction and noise. Utility Model Content

[0005] In the above solution, the lower connecting plate is provided with a lug structure, and both the lug structure and the crossbeam are provided with vertical through-holes. The longitudinal beam is provided with lateral through-holes. The interior of the armrest lower shell is provided with mounting posts in corresponding directions corresponding to the vertical and lateral through-holes. The mounting posts have threaded holes in their centers, and each threaded hole is equipped with a bolt. The bolt passes through the vertical or lateral through-hole and screws into the corresponding threaded hole to achieve a fixed connection between the armrest lower shell and the armrest frame. Bolts are drilled in both the transverse and longitudinal directions of the armrest frame to ensure the stability of the connection between the armrest frame and the armrest lower shell.
[0006] In the above solution: the longitudinal beam is provided with strip reinforcement ribs to increase the rigidity and strength of the longitudinal beam.
[0007] In the above scheme: a headrest guide sleeve for installing the headrest rod is provided on the guide sleeve mounting sheet metal, and a through hole for the headrest rod to pass through is provided at the front end of the armrest lower shell, so as to facilitate the movement of the headrest rod and the armrest structure together.
[0008] In the above solution, the longitudinal beam is in the shape of a semicircular tube or a semi-square tube, and the skeleton connecting tube is welded to the inner wall of the longitudinal beam, which has a simple structure and is easy to process.
