Coaxial damping circulating air door structure
Coaxial damping circulating air door structure
The invention discloses a coaxial damping circulation air door structure which comprises an outer circulation fresh air opening and an inner circulation air return opening, an inner and outer circulation air door is arranged between the outer circulation fresh air opening and the inner circulation air return opening, and the inner and outer circulation air door is connected with a first servo motor through a circulation air door rocker arm. And a damping air door is arranged in a shaft hole of the inner and outer circulation air door. In the outer circulation fresh air mode, the introduced fresh air volume can be determined by adjusting the opening degree of the damping air door, so that the fresh air heat load is reduced, and the refrigerating and heating requirements of the air conditioning system are quickly met; in the outer circulation fresh air mode, passengers can adjust the position of the damping air door, so that the air outlet of an HVAC in a passenger compartment can ensurestable air volume at different running speeds of the whole vehicle, and a comfortable environment is provided for the driving and riding of the whole vehicle; the inner and outer circulation air doorand the damping air door are designed to be of a coaxial structure, the space size needed by the two air doors is greatly reduced, and the size of an HVAC air inlet side shell can be conveniently optimized.
本发明公开了一种同轴阻尼循环风门结构，包括外循环新风口和内循环回风口，所述外循环新风口和所述内循环回风口之间设置有内外循环风门，所述内外循环风门通过循环风门摇臂与第一伺服电机连接，所述内外循环风门的轴孔内设置有阻尼风门。本发明在外循环新风模式下，可通过调节阻尼风门的开度决定引入的新风风量，进而减少新风热负荷，快速实现空调系统的制冷制热需求；在外循环新风模式下，乘客通过调节阻尼风门的位置，可使整车在不同行驶的车速下，乘员舱内HVAC的出风口都保证稳定的风量，为整车驾乘提供舒适环境；内外循环风门与阻尼风门采用同轴结构的设计，极大的减少了两扇风门所必须的空间尺寸，便于对HVAC进风侧壳体的尺寸进行优化。
