The air outlet shell and the air outlet panel cooperate with each other, and the blade structure is movably arranged on the air outlet panel. The decorative structure is different from the traditional structure. The decorative structure is an integral through-structure, and a gap is provided between the decorative structure and the blade structure, which is fixed on the air outlet panel. The air outlet styling innovation scheme is different from the traditional air outlet disconnected blades and decorative strips. The present invention adopts a continuous electroplated decorative strip to ensure the overall continuity of the air outlet styling effect.

[0033] The present invention also includes an upper blade bracket, a connecting rod and a connecting rod damping; the blade structure includes an upper blade and a lower blade, the upper blade is arranged close to the decorative structure, and the upper blade is located between the decorative structure and the lower blade; the upper blade and the lower blade are connected by a shift fork, and the upper blade and the lower blade can flexibly adjust their positions.

[0034] The upper blade bracket is fixed on the air outlet panel or the air outlet shell, the upper blade is hingedly connected to the upper blade bracket through a rotating shaft, the upper blade bracket is provided with a slide groove, one end of the connecting rod is arranged in the slide groove through a connecting rod damping, and the other end of the connecting rod is hingedly connected to the rear of the upper blade.

[0035] The automobile instrument panel air outlet assembly structure is reasonably designed, and the air outlet decorative strip is an integrally connected structure, which improves the visual effect of the shape. The continuous overall electroplating decorative strip scheme improves the quality and refinement of the air outlet assembly, and the upper blade bottom connecting rod and connecting rod damping optimization improve the consistency of the air outlet operating force and the operating feel, avoiding the risk of abnormal noise when operating the air outlet at the extreme position.

[0036] The decorative structure includes a decorative strip frame and a decorative strip arranged on the decorative strip frame. The decorative strip is an integral continuous structure, and the decorative strip frame is arranged on the air outlet panel. Specifically, the decorative strip frame and the decorative strip are both integral strip structures. The decorative strip frame and the decorative strip are welded or clamped together. The decorative strip frame and the decorative strip are first fixed together, and the decorative strip frame is clamped and installed on the air outlet panel.
