The utility model provides an external active air-inlet grille, and belongs to the technical field of automobiles. The problem that an
actuator of an existing active air inlet grille is prone to damage is solved. The utility model discloses an external active air-inlet grille which comprises a frame body, blades, a driving piece, a connecting rod
assembly and a self-locking piece. According to the utility model, when the active air-inlet grille is in a
closed state, the blades block the air vents, the self-locking pieces enable the connecting rod assemblies to be in a self-locking state, when the blades are subjected to oncoming wind or water, the blades have the tendency of turning over towards the interior of the frame body, and in the process, the blades can transmit the received force to the connecting rod assemblies, so that the connecting rod assemblies can turn over towards the interior of the frame body. The self-locking piece locks the connecting rod
assembly at the moment, so that force borne by the connecting rod
assembly can be transmitted to the self-locking piece, the connecting rod assembly is prevented from moving in the frame body at the moment, namely torsion generated on the connecting rod assembly is prevented from being transmitted to the driving piece, and the effect of protecting the driving piece is achieved.
