Control system for air outlet of air conditioner in vehicle and air conditioner for vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing control systems for vehicle air conditioner outlets require multiple motors to control horizontal vanes, longitudinal vanes, and ventilation doors, leading to increased costs and complexity.
Innovation Solution
A control system utilizing a single motor with three clutches, each controlling one of the horizontal vane, longitudinal vane, or ventilation door, simplifying the structure and reducing the number of parts by using a deflector rod to engage and disengage with the clutches for independent adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If three motors are used to control horizontal vane, longitudinal vane, and ventilation door respectively, then each component can be controlled independently, but the cost and device complexity increase
Solution Approach 1:
The patent combines three separate motors into a single motor that controls all three air outlet components (horizontal vane, longitudinal vane, and ventilation door) through a shared transmission mechanism. The motor shaft is directly connected to the ventilation door, and additional transmission paths extend to control the horizontal and longitudinal vanes, eliminating the need for three separate motors while maintaining independent control capability.
Solution Approach 2:
The single motor serves multiple functions by controlling three different air outlet components through a multi-path transmission system. The motor's rotation can be distributed to the ventilation door, horizontal vane, and longitudinal vane simultaneously or independently, making one motor universal for all three control functions.

3Device complexity
If only ventilation door is adjusted electronically while horizontal and longitudinal vanes are manually adjusted, then the system is simpler, but the automation level is lower
Solution Approach 1:
The single motor serves multiple functions by controlling three different air outlet components (ventilation door, horizontal vane, and longitudinal vane) through a multi-path transmission system. The motor's rotation can be distributed to all three components simultaneously or independently, achieving full electronic control and automation for the air outlet while using only one motor.
Solution Approach 2:
The transmission mechanism allows dynamic distribution of the motor's rotational output to different components based on control needs. The system can selectively engage transmission paths to the ventilation door, horizontal vane, longitudinal vane, or any combination thereof, enabling flexible and complete automation of air outlet control.

AI summary
A control system for an air outlet of an air conditioner in a vehicle includes a motor, a first clutch configured to control a horizontal vane of the air outlet, a second clutch configured to control a longitudinal vane of the air outlet, a third clutch configured to control an opening degree of a ventilation door of the air outlet, and an engaging element of the motor being connected to the motor, for engaging the clutches. The motor adjusts the horizontal vane of the air outlet when the engaging element is engaged with the first clutch, the motor adjusts the longitudinal vane of the air outlet when the engaging element is engaged with the second clutch, and the motor adjusts the opening degree of the ventilation door of the air outlet when the engaging element of the motor is engaged with the third clutch.
