The invention relates to an air outlet structure of a double-layer hidden blade, and belongs to the technical field of automobile air conditioning systems. The air outlet structure comprises an air outlet shell and an upper-layer air guide blade; an air exhaust channel is arranged in the air outlet shell, and an air outlet panel is arranged at the outlet end of the air outlet shell. The upper-layer air guide blade comprises a middle blade and hidden blades, wherein the middle blade and hidden blades are located in the exhaust channel and rotationally connected with the inner wall of the air outlet shell, and the hidden blades are located above the middle blade and hidden on the inner side of the air outlet panel. The hidden blades comprise a front hidden blade which forms a triangular cavity with the inner wall of the air outlet panel, and a rear hidden blade which is hinged with the front hidden blade and blocks the opening end of the triangular cavity, and the opening end of the triangular cavity faces the inlet end of the air outlet shell. The rear hidden blades, the front hidden blades and the inner wall of the air outlet panel form the closed triangular cavity, air flowing out of the exhaust channel cannot form vortexes and noise in the closed triangular cavity, the comfort of passengers is improved, and air flow resistance is reduced.

    本申请涉及一种双层隐藏式叶片的出风口结构,属于汽车空调系统技术领域,包括:出风口壳体,其内设有排风通道,在出风口壳体的出口端设有出风口面板;上层导风叶片,其包括位于排风通道内且与出风口壳体的内壁转动连接的中间叶片和隐藏叶片,隐藏叶片位于中间叶片的上方且隐藏于所述出风口面板的内侧;隐藏叶片包括与出风口面板的内壁形成三角空腔的前隐藏叶片,三角空腔的开口端朝向出风口壳体的入口端,以及与前隐藏叶片铰接且封堵三角空腔开口端的后隐藏叶片。本申请的后隐藏叶片、前隐藏叶片与出风口面板的内壁形成封闭三角形空腔,从排风通道流出的空气不会在此形成涡流和噪音,提高了乘员的舒适性,并减少了空气流阻。
