摘要: 为提升嵌入式双轴铰链冰箱的开门体验,针对冰箱开门阻力的特性,设计了一种推杆加速伸出的自动开门机构。该机构采用高速微型电机驱动、圆柱齿轮和非圆齿轮组合传动的方式,实现了体积小、启动推力大的设计要求。利用非圆齿轮变速传动的特性,加速推动门体以获得较大的转动惯量,可适配单轴铰链冰箱和双轴铰链自由嵌入式冰箱。该自动开门机构及其零部件通过了10万次开关门循环测试,具有很高的可靠性。机构内部零件少,且大部分关键结构件均采用注塑成型工艺,成本低、整体结构装配简单、可制造性强,有利于冰箱自动开门技术的推广和普及。

Abstract: In order to improve the door opening experience of the double-axis hinged embedded refrigerator, a push-rod accelerated automatic door-opening actuator was designed based on the characteristics of the door-opening resistance of the refrigerator. The actuator is driven by high speed micro motor. And the actuator adopts a combination transmission of cylindrical gear and non-circular gear to achieve the design requirements of small size and large starting thrust. By utilizing the characteristics of non-circular gear variable speed transmission, the door is accelerated to obtain a larger moment of inertia, which can be adapted to both single-axis hinged refrigerators and double-axis hinged embedded refrigerators. The actuator and its components have high reliability, and have passed 100000 door opening-closing cycle tests. The actuator has few parts, and most of the key structural components are injection molded. The actuator is conducive to the promotion and popularization of automatic door opening technology for refrigerators, with low cost, simple assembly, strong manufacturability.

Key words: Refrigerator, Automatic door opening, Variable transmission, Reliability
