According to the second conception of the application, the structure to the connecting piece is improved, the orbit of connecting piece on the cam sets up to the recess at two sides respectively, and the orbit of two recesses is different, set up the connecting piece into gliding jack catch pole and pin each other, the block is in two recesses respectively, when the cam begins to rotate, jack catch pole and pin take place to slide according to the distance of recess, realize inside switching, can accomplish the locking or the loosening of both ends connecting piece and aviation baffle through the rotation of cam, make the motion restriction of aviation baffle change along with going on of mechanism's motion, need not increase power spare, the structure is simplified, structural stability has been increased.
According to the third conception of the application, the connecting piece is improved, the elastic piece is arranged between the claw rod and the stop lever, when the cam finishes moving or the cam begins to reset, the movement potential energy between the claw rod and the stop lever is ensured, and the locking is avoided.
According to the fourth concept of the application, the driving mechanism is further improved, when the air deflector is in a closed state, a switch is arranged at the position of the hinged end of the connecting rod and the cam, the movement structure is detected to return to the initial position by the switch, and the driving mechanism is rotated after the movement structure is confirmed to return to the initial position, so that the stability of the driving mechanism in rotation is ensured, and the collision of the driving direction of the power part and the preset movement range of the structure is avoided, and the equipment is locked or damaged.
Those of ordinary skill in the art will understand that: although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that various changes, modifications and substitutions can be made without departing from the spirit and scope of the utility model as defined by the appended claims. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
