The upper layer blade is arranged behind the decorative strip framework, and the gap between the upper layer blade and the decorative strip framework is greater than or equal to 1 mm. The knob structure comprises a knob base and a knob arranged on the knob base. The knob base is clamped on the upper layer blade, and the knob is provided with a knob decorative strip 5. The position of the blade is adjusted through the knob structure, so that the wind direction of the air outlet is adjusted. The knob structure is integrated on the blade structure, and is arranged separately from the decorative structure. Therefore, the decorative strip can be designed in a penetrating structure, so that the quality and delicacy of the air outlet assembly are improved.

[0042] As shown in Figure 1 , the air outlet assembly of the automobile instrument panel is divided into modules, and the decorative structure is an integral penetrating structure. Each module has the same structure, and a group of modules are arranged transversely and side by side. Each module comprises an air outlet shell, an upper layer blade, a pair of upper layer blade supports, a pair of rotating shafts, a pair of connecting rods, a pair of connecting rod dampers, a yoke, a lower layer blade, and a lower layer blade support.
