Description

电风扇摆角调节采样装置 技术领域
本发明涉及一种摆角调节电风扇，尤其是一种电风扇摆角调节采样装置。
背景技术
现有技术中，有一种电风扇摇头摆角调节装置(中国专利申请号201710491195.8)技术方案，它展示了一种使用交流电机的电风扇摆角调节装置以及相应的磁敏式电信号采样装置，参见其说明书原文第7页第21行至第8页第8行，结合图5图6的描述得知，它包括交流电机，由蜗杆—蜗轮—蜗轮轴—大齿轮动力传递机构、行星轮曲柄机构和大齿轮—棘爪离合装置组成的变角齿轮箱，变角齿轮箱壳体装有磁吸装置，磁吸装置通过导线与调角控制芯片连接，在交流电机转子蜗杆置有支架，支架内置有永磁体，永磁体成为与转子一起旋转的转子标志物，在永磁体对应间隙置有霍尔传感器，霍尔传感器固装在电机壳体内，霍尔传感器通过导线与调角控制芯片连接，从而在调角过程中，霍尔传感器在监测交流电机转子永磁体运转时，能获取到与行星轮曲柄回转动作轨迹相对应的采样电信号数据，经导线实时反馈至调角控制芯片，实现摆角调节，这种置有磁敏式电信号采样装置的电风扇摆角调节装置，具有无触头磨损，寿命长，分辨率高的优点，然而，由于永磁体和霍尔传感器固装在交流电机壳体内，霍尔传感器 为低压弱电元件，交流电机为高压元件，形成高低压元件混装，在电机车间装机和打高压检测中，出现生产工艺复杂，装配慢，检测击穿多，拆解电机头返修难，产品不良率高的情况，到电风扇流水线总装，会二次出现生产装配慢，击穿多，拆解电机头返修难，产品不良品率高的情况，显然，这种设置在交流电机壳体内混装高低压元件的电信号采样装置，是需要改善的。

上述的转子标志物的相应间隙置有转子位置传感信号获取装置的另一种技术方案，可采用光电式转子位置传感信号获取装置技术方案，在采用光电式转子位置传感信号获取装置技术方案时，上述的转子标志物是在交流电机伸出电机壳体外的转子轴端置有反光斑，在变角齿轮箱对应反光斑的相应间隙置有光电传感器，光电传感器通过导线与调角控制芯片连接。
由于本发明将原技术设置在交流电机壳体内的转子标志物与转子位置传感信号获取装置，改设在交流电机壳体外，永磁体、导磁体或反光斑为耐压元件，安装在交流电机壳体外的转子轴端，装卸方便，本身不存在打高压击穿问题，霍尔传感器、磁敏式接近开关或光电传感器以非接触的分离方式设置在由绝缘材料组成的变角齿轮箱对应位置中，脱离交流电机内部高压环境，从而在交流电机壳体外形成一组高低压元件分离布置，装配方便，高压检测不易击穿，返修快捷，生产率高，不良品率低的电风扇摆角调节采样装置。
