AI Technical Summary
The existing automotive air conditioning unit damper mechanism has a complex structure, which is prone to jamming after prolonged use, and bacteria and odors can easily grow when the airflow inside the air conditioning unit stops.
The system employs a damper mechanism design that includes a first partition plate, a second partition plate, a baffle, a first drive device, and a dehumidification device. The baffle is driven to move by an electromagnet, and the system works in conjunction with a conduction device to expel moisture when there is no airflow, thus keeping the air conditioning unit dry.
The simplified damper mechanism reduces jamming and keeps the air conditioning unit dry when there is no airflow, reducing bacterial growth and odor.
