The air inlet structure comprises an outer shell, an air inlet cavity is formed in the outer shell, the two opposite sides of the air inlet cavity are the open side and the closed side respectively, and an air inlet and an air outlet are formed in the open side at the same time; at least one main air inlet channel and at least one auxiliary air inlet channel are formed in the outer shell. Each main air inlet channel is arranged on the closed side and communicated between the air inlet side and the air outlet of the air inlet cavity, and each auxiliary air inlet channel is arranged on the open side and communicated between the air outlet side and the air outlet of the air inlet cavity. The air inlet side is opposite to the air inlet, and the air outlet side is opposite to the air outlet; the length of the main air inlet channel is larger than that of the auxiliary air inlet. The auxiliary air inlet channel is provided with a valve; when the rotating speed of the engine does not exceed the set rotating speed, the valve is closed, only the main air inlet channel carries out air inlet, and medium-low-speed resonance air inlet is achieved. On the contrary, the valve is opened, the main air inlet channel and the auxiliary air inlet channel conduct air inlet simultaneously, high-speed inertia air inlet is suitable, and adaptability is good.

    本发明公开了一种进气结构及摩托车,进气结构包括外壳体,外壳体内形成有进气腔,进气腔的两相对侧分别为敞开侧和封闭侧,敞开侧同时设有进气口和出气口;外壳体内形成有至少一条主进气道和至少一条副进气道;每条主进气道设于封闭侧并连通于进气腔的进气侧与出气口之间,每条副进气道设于敞开侧并连通于进气腔的出气侧与出气口之间;进气侧与进气口相对,出气侧与出气口相对;主进气道的长度大于副进气口的长度;副进气道设有阀门;当发动机的转速未超过设定转速时,阀门关闭,仅主进气道进气,适于中低速谐振进气。反之,阀门打开,主进气道与副进气道同时进气,适于高速惯性进气,适应性较好。
