在组装工作或用户维修保养或更换某些零部件时，可通过简单工具即可将芯轮组件1、机芯组件2、控制器组件3和齿轮组件4等整体拆除。
现有技术(一种紧凑型电动助力自行车中置电机，申请号为202023123948.6)中，在其电机轴需要更换的条件下，或者在其电机轴需要保养维护的条件下，需要首先拆除电机外壳和定子204的组合物，使得电机轴依 然保留在前述的壳状部件上，然后将设置在壳状部件上的螺钉或销子、以及覆盖于小齿轮轴的盖板拆除之后，才能够取下电机轴。
本实施例的中置电机，在需要更换电机轴的条件下，或者需要对电机轴进行保养的条件下，仅需要采用简单工具即可将机芯组件2整体从芯轮组件1上拆除；与前述的现有技术对比，至少节省了拆除螺钉或销子、以及覆盖于小齿轮轴的盖板的工作；在更换了电机轴之后，再将机械组件整体的安装在芯轮组件1上，相对于前述的现有技术，至少节省了安装螺钉或销子、以及覆盖于小齿轮轴的盖板的工作。显然，本实施例的中置电机，对于电机轴的拆装效率更高。

本实施例的中置电机，在需要更换齿轮组件4的其中一个部件的情况下，例如：齿轮轴，可采用简单工具，直接将齿轮组件4整体从芯轮组件1上拆除；相对于前述的现有技术，至少节省了将电机轴、盖板和螺钉或销子拆除的工作；在更换了其中一个部件之后，采用简单工具，将齿轮组件4整体安装于芯轮组件1上，相对于前述的现有技术，至少节省了将电机轴、盖板和螺钉或销子安装的工作。
因此，本实施例提供的中置电机，通过至少设置有芯轮组件、机芯组件、控制器组件和齿轮组件，且芯轮组件、机芯组件、控制器组件和齿轮组件分别被设置为模块状的整体结构，且相互之间采用整体连接的方式，解决了现有技术中的中置电机实现模块化的连接结构的技术问题。

在口部处，设置有密封圈203，在机芯组件2实际安装于芯轮组件1时，密封圈203用于密封机芯外壳201与芯轮组件1之间的间隙。

具体的，牙盘组件5包括牙盘501、牙盘座502、链罩503、固定螺丝504、 芯轮锁母505；
牙盘座502被设置在牙盘501和链罩503之间，且牙盘座502、链罩503和牙盘501通过固定螺丝504连接；牙盘座502设置有通孔，该通孔的直径大于中轴102的直径，使得中轴102可穿透该通孔，以及，牙盘座502上设置有安装凸台，使得牙盘座502可通过安装凸台插入至芯轮103组件1上的第二安装通道内；在实际设置中，前述的芯轮套108的其中一端可插入至牙盘座502上的通孔，并且在芯轮套108的内圆周面上设置有内螺纹，使得芯轮锁母505在套设与中轴102之后，可一次插入牙盘座502和芯轮套108，最终，芯轮锁母505的外螺纹与芯轮套108的内螺纹连接；在芯轮锁母505连接之后，通过锁母油封506密封中轴102和芯轮锁母505之间的间隙。
本实施例提供的中置电机，参见图3或图11，还包括传感器组件6；
传感器组件6被配置为套设在中轴102上，传感器组件6设置在第二安装通道内；
传感器组件6和控制器组件3电性连接。
其中，传感器组件6优选的配置为力矩传感器组件6；具体的，力矩传感器组件6至少包括应变片，通过应变片检测到中轴102的扭力变化而导致的钢体材料变形，使得应变片产生电信号且能够将电信号发送至前述控制器组件3的控制器。
除前述内容之外，本实施例提供的中置电机，还包括噪音传感器；
噪音传感器设置在基座上，其中，噪音传感器至少用于检测机芯组件和所述齿轮组件的啮合处的噪音。
噪音传感器与前述的控制器组件电性连接，一方面，控制器组件可向噪音传感器提供电能，使得噪音传感器能够采集声音或噪音；另一方面，参见图13，图13中展示了中置电机的电性连接图，其中，控制器组件分别与力矩传感器a1和噪音传感器a7。噪音传感器在接收到声音或噪音时产生噪音电信号，该噪音电信号反馈至控制器组件，并由控制器组件进行后续处理。
在实际应用中，参见图12，图12中展示了本实施例的电动助力自信车的一种优选电性连接图，其中，中置电机的控制器组件分别与力矩传感器a1、尾灯a1、电池a3、制动装置a4、整车控制器a5(整车控制器包括仪表、本地显示屏和/或通讯模块)、前灯a6。控制器组件与电动助力自行车的整车控制器通讯连接，这使得控制器组件能够将接收到的噪音电信号转换为噪音数据，并将噪音数据发送至整车控制器；应当理解的是，将传感器的电信号转换为数据，这是本领域技术人员所知晓的公知常识，这里不再赘述。
整车控制器将接收到的噪音数据进行如下两种方式的处理：
方式一：如果整车控制器没有配置网络模块，仅配置有本地显示器，那么，整车控制器可将当前接收到的噪音数据通过本地显示器显示，以便于用户通过本地显示器观察到噪音数据；此外，可以在整车控制器内设置预设噪音阈值，例如：55分贝，如果整车控制器接收到的噪音数据超出噪音阈值(即大于55分贝)，则整车控制器通过本地显示器向用户发出报警，报警可采用闪烁屏幕或闪烁指示灯的方式实现。
方式二：如果整车控制器配置有网络模块，那么，整车控制器可将前述接收到的噪音数据通过网络模块上传至用户的电子设备或服务器，电子设备例如：手机、平板、电脑等；服务器例如：云端服务器或雾端服务器；同样的，可在整车控制器内设置预设噪音阈值，并通过本地显示器向用户提示当前的噪音数据或报警，也可以将预设噪音阈值设置在用户的电子设备的预设程序内或服务器内，例如：电子设备的APP内，云端服务器的数据库内，当电子设备或服务器接收到的噪音数据大于预设噪音阈值时，电子设备通过其本身的屏幕或指示灯或声音向用户发出提示，或者服务器将报警信息发送至用户的电子设备上，再通过电子设备通过其本身的屏幕或指示灯或声音向用户发出提示。
中置电机在出厂之前需要进行噪音检测，一方面需要符合响应的法律法规的噪声标准，另一方面，对中置电机的产品本身形成出厂数据，便于后续的溯源。在中置电机实际应用于电动助力自行车时，若机芯组件或齿轮组件没有发 生磨损或故障、或者磨损在合理的范围内，则噪音传感器检测到的噪音应当低于预设噪音阈值；反之，如果机芯组件或齿轮组件产生超出合理范围的磨损、或者产生了故障，则噪音传感器能够检测到超出预设噪音阈值的噪音。换个角度来说，如果噪音传感器已经检测到超出预设噪音阈值的噪音，说明机芯组件和/或齿轮组件因此产生了故障或超出可以范围的磨损，从而能够通过前述报警的方式，提示用户检测、维护中置电机，进而保证用户的使用安全。
实施例2：
在本实施例中，提供一种电动助力自行车，包括如实施例1提供的中置电机。
本实施例中的中置电机，与前述实施例1中的中置电机的结构和效果完全相同，这里不再赘述。
参见图12，图12中展示了本实施例的电动助力自信车的一种优选电性连接图，其中，中置电机的控制器组件分别与力矩传感器a1、尾灯a1、电池a3、制动装置a4、整车控制器a5(整车控制器包括仪表、本地显示屏和/或通讯模块)、前灯a6。
参见图13，图13中展示了中置电机的电性连接图，其中，控制器组件分别与力矩传感器a1和噪音传感器a7。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
