The invention relates to an active air inlet grille system. The active air inlet grille system comprises a front flow guide frame and a rear flow guide frame, a rear flow guide frame; the two ends, in the length direction of the vehicle, of the active air inlet grille are each provided with a connecting port. The connecting port close to one end of the front bumper is detachably connected with the front flow guide frame; and the connecting port at one end far away from the front bumper is detachably connected with the rear flow guide frame so as to form a communicated air inlet structure. The front flow guide frame and the rear flow guide frame are detachably connected to the two connecting ports respectively, so that the front flow guide frame, the rear flow guide frame and the rear flow guide frame can be manufactured and produced independently and can be replaced independently according to needs; for example, when the shapes of the front protectors suitable for different vehicle types are different and the interfaces of the front flow guide frame are different, only the front flow guide frame needs to be replaced and remanufactured and is replaced by the interface matched with the front protectors, and the rear flow guide frame and the active air inlet grille do not need to be changed, so that the development and manufacturing cost of the vehicle is reduced; and the problem that the investment cost is high due to the fact that an original whole double-color injection molding part needs to be reopened is solved.

本申请涉及一种主动进气格栅系统，其包括：前导流框；后导流框；主动进气格栅，其沿车辆长度方向的两端均具有连接端口；靠近前保一端的连接端口可拆连接所述前导流框；远离前保的一端的连接端口可拆连接所述后导流框，以形成相连通的进气结构。前导流框和后导流框分别可拆连接在两个连接端口上，使三者可以单独进行制造生产，可以根据需要进行单独的更换；例如当适应不同车型的前保造型不同，与前导流框的接口也不同，此时只需要更换和重新制造前导流框，换成与前保适配的接口即可，而对于后导流框和主动进气格栅可以不进行改变，从而减少车辆的开发制造成本，也改变了原本整个双色注塑零件需要重开模具所带来的投入成本高的问题。
