摘　　要：运动部件轻量化设计,是保证热泵空调器导风部件使用可靠性的重要方法之一。大导风板作为热泵空调器室内机最大的运动部件,一般采用外金属/内塑料的复合设计;外观设计美观,但是重量重,且生产过程复杂。为了降低导风板部件重量和提高生产效率,采用塑料件替代金属件进行全新设计。利用Creo对全新设计的热泵空调器全塑导风板进行结构设计和最大力矩计算;并对全塑导风板与外金属/内塑料复合导风板相比进行装配效率对比分析。结果表明,在导风效果和总质量相当的情况下,全塑导风板的驱动力矩下降11.7%,装配效率提高50%以上。The light-weight design of moving parts was one of the important methods of ensuring the reliability of the air-defiector-part of heat pump air conditioner. As the largest moving part of the heat pump air conditioner indoor unit, the large guide air defiector was generally processed with composite design: metal(outer)/plastic(inner). The appearance was beautiful, but weight was heavy, and the production process was complicated. In order to reduce the weight and improvement of productive efficiency, a plastic component was used for a new design. Researched with Creo, the new structural design and maximum driving torque calculations of the heat pump air conditioning allplastic air defiector were studied. And the assembling efficiency of the all-plastic air defiector was compared with the outer metal/inner plastic composite air defiector. The results showed that, at comparable total mass, the maximum driving torque of the all-plastic air defiector reduced by 11.1%, the assembling efficiency was improved by more than 50%.
