[0002] In the mode switching of vehicle air conditioners, a driving component is required to drive. In order to reduce the use of driving motors, a shaft groove or a gear structure is used to enable a driving motor to drive the movement of multiple components.

[0003] After retrieval, Chinese Patent with application number 202310497314.6 discloses an automotive air-conditioning transmission mechanism. The left defrost air damper and the right defrost air damper are installed on the air outlet housing. The two defrost linkages are installed on the two defrost air dampers by means of ball head connections. The other ends of the two defrost linkages are fixed to the defrost drive disk by means of ball head bayonets. There is a shaft hole in the middle of the defrost drive disk. The positioning and guiding cylinder in the middle of the mode disk is fixed in the middle shaft hole of the defrost drive disk. A spring is sleeved on the two transmission rods of the mode disk. The other ends of the two transmission rods are fixed to the defrost drive disk by bayonets. The face-blowing swing rod and the face-blowing linkage are connected by a ball head. The face-blowing linkage and the face-blowing air damper are connected by a ball head. The other end of the face-blowing swing rod is installed on the mode disk by a ball head.
