The invention discloses a PCB carbon film actuator for an automobile air conditioner. The PCB carbon film actuator is composed of a shell, a PCB, a first rotating gear, a second rotating gear, a third rotating gear, an output gear and a driving assembly. The carbon film of the PCB carbon film actuator has the advantages of being resistant to abrasion and uniform in film resistance change, the service life of the actuator is prolonged, the control precision of an air conditioner is improved, the interaction between carbon black and resin can be improved while the carbon black is evenly dispersed through the self-made dispersing agent, and therefore the bonding performance between the carbon black and a substrate is improved; and nano silicon dioxide is added, so that the wear resistance is improved.
本发明公开一种汽车空调用PCB碳膜执行器,由壳体、PCB线路板、第一转动齿轮、第二转动齿轮、第三转动齿轮、输出齿轮及驱动组件构成;本发明PCB碳膜执行器的碳膜具有耐磨、膜电阻变化均匀的特点,提高了执行器的使用寿命和对空调的控制精度,采用自制分散剂使碳黑均匀分散的同时可以提高碳黑与树脂的相互作用从而提高与基板的粘接性能,并加入纳米二氧化硅提高了其耐磨性能。
