Description

Swing blade driving assembly and air conditioner indoor unit with same Technical Field The utility model relates to the field of air conditioning equipment, in particular to a swing blade driving assembly and an air conditioner indoor unit with the same. Background In the indoor unit of the air conditioner, the swing blades play a role in adjusting the air outlet direction, and the rotation of the swing blades is usually realized by driving a connecting crank connected with the swing blades by the rotation of an output shaft of a motor. Typically the connecting cranks are spaced or contact disposed on one side of the motor case. In the rotation process of the connecting crank, the connecting crank can possibly have overlarge contact area with the motor box, so that larger friction force exists between the connecting crank and the motor box, energy loss can be caused, a large amount of noise is generated when the connecting crank rotates, and the use experience of a user is reduced. Disclosure of utility model In view of the above problems, the present utility model has been made to provide a swing blade driving assembly and an indoor unit of an air conditioner having the same, which overcome or at least partially solve the above problems, and can reduce friction between a connection crank and a motor box, reduce energy loss, and reduce noise generated when the connection crank rotates, thereby achieving the purpose of improving user experience.
