为了进一步地提高连接套筒与外壳部之间的连接强度，保证本申请的脚踏装置的工作稳定性，本实施例中的检测部还可以包括第二弹性件，连接套筒21的外壁上还设置有第三连接凸台212，第三连接凸台212与第一连接凸台211以连接套筒21的轴线为中心线对称设置，安装空间的内壁与第三连接凸台212相对的一端设置有第四连接凸台12，第二弹性件的第一端连接在第三连接凸台212上，第二弹性件的第二端连接在第四连接凸台12上，所述安装空间的内壁通过所述第一弹性件和所述第二弹性件与所述连接套筒21的外壁连接，第二弹性件能够随骑行者的脚踏力的变化而发生弹性形变。安装时，工作人员将本实施例中的第一弹性件的第一端连接在第一连接凸台211上，将本实施例中的第一弹性件的第二端连接在第二连接凸台11上，并将本实施例中的第二弹性件的第一端连接在第三连接凸台212上，将本实施例中的第二弹性件的第二端连接在第四连接凸台12上，进而实现了通过第一弹性片和第二弹性片共同支撑连接套筒，使连接套筒21与脚踏面的距离可变化的同时，进一步的加强了连接稳定性。
在一些可选的实现方式，本实施例中的第二弹性件可以包括多个第二弹簧片32，多个第二弹簧片32可以沿连接套筒21的轴线方向间隔设置，以进一步提高连接强度。
在一些可选的实现方式，检测部还可以包括形变传感器40和控制器， 控制器通过形变传感器40确定骑行者施加在所述脚踏面上的脚踏力。在示例1中，第一弹性件上可以设置有形变传感器40，以检测第一弹性件的弹性形变，所述检测部通过所述第一弹性件的弹性形变确定所述脚踏面上的脚踏力；作为一示例，控制器可以通过形变传感器40检测的所述第一弹性件的弹性形变确定所述脚踏面上的脚踏力。在示例2中，所述第二弹性件上可以设置有形变传感器40，以检测所述第二弹性件的弹性形变，所述检测部通过所述第二弹性件的弹性形变确定所述脚踏面上的脚踏力；作为一示例，控制器可以通过形变传感器40检测的所述第二弹性件的弹性形变确定所述脚踏面上的脚踏力。在示例3中，所述第一弹性件上和所述第二弹性件上均可以设置有形变传感器40，以检测第一弹性件的弹性形变和第二弹性件的弹性形变，所述检测部通过所述第一弹性件的弹性形变和所述第二弹性件的弹性形变确定所述脚踏面上的脚踏力；作为一示例，控制器可以通过形变传感器40检测的所述第一弹性件的弹性形变和形变传感器40检测的所述第二弹性件的弹性形变确定所述脚踏面上的脚踏力。需要注意的是，这里，形变传感器40的数量为至少两个，至少一个形变传感器40设置在所述第一弹性件上，至少一个形变传感器40设置在所述第二弹性件上。本实施例具有三种不同的形变传感器安装方式，工作人员可根据实际生产情况进行选择。
由于本实施例中的外壳部在受到骑行者的脚踏力时，连接套筒与安装空间的上端壁的距离会发生变化，为了给连接套筒的运动提供空间，进而实现第一弹性件及第二弹性件的变形，参见图4所示，本实施例中的第一弹性件的第一端和所述第二弹性件的第一端均可以设置有腰形孔，所述腰形孔的长度方向垂直于所述连接套筒的轴向，第一弹性件的第一端和第二弹性件的第一端均通过螺钉穿过腰形孔固定在连接套筒上；所述脚踏面受力时，所述安装空间的上端壁能够向靠近所述连接套筒21的方向移动，所 述第一弹性件和所述第二弹性件通过所述腰形孔能够分别向远离所述连接套筒21的方向移动。这里，安装空间的上端壁为设置有脚踏面的端壁。
在一些可选的实现方式，检测部还可以包括控制器和距离传感器，控制器通过距离传感器确定骑行者施加在所述脚踏面上的脚踏力。例如，连接套筒21的靠近安装空间的上端壁的筒壁上设置有第一距离传感器，所述第一距离传感器以检测所述连接套筒21与所述安装空间的上端壁之间的距离；检测部通过所述连接套筒21与所述安装空间的上端壁之间的距离确定骑行者施加在所述脚踏面上的脚踏力；作为一示例，控制器通过所述第一距离传感器检测的所述连接套筒21与所述安装空间的上端壁之间的距离确定骑行者施加在所述脚踏面上的脚踏力。又例如，安装空间的上端壁上设置有第二距离传感器，所述第二距离传感器以检测所述连接套筒21与所述安装空间的上端壁之间的距离；检测部通过所述连接套筒21与所述安装空间的上端壁之间的距离确定骑行者施加在所述脚踏面上的脚踏力；作为一示例，控制器通过所述第二距离传感器检测的所述连接套筒21与所述安装空间的上端壁之间的距离确定骑行者施加在所述脚踏面上的脚踏力。
在其他实现方式中，脚踏装置可以既设置有形变传感器40，也设置有距离传感器；正常工作时只启用一个传感器(例如，形变传感器40)，当启用的一个传感器(例如，形变传感器40)出现问题时，启用另一个传感器(例如，距离传感器)。通过双重检测，避免了单一传感器出现故障而无法检测。
为了防止骑行者用力过大，使连接套筒21与脚踏面之间的距离变化过大，而使第一弹性件和/或第二弹性件发生不可逆的变形而损坏，所述的脚踏装置还设置有限位结构。例如，本实施例中的安装空间的上端壁与连接套筒21对应的位置上设置有第一限位凸块，通过所述第一限位凸块限制所述安装空间的上端壁相对于所述连接套筒21移动的距离。又例如，参见图 3所示，所述连接套筒21靠近所述安装空间的上端壁的筒壁上设置有第二限位凸块50，通过所述第二限位凸块50限制所述安装空间的上端壁相对于所述连接套筒21移动的距离。再例如，本实施例中的安装空间的上端壁与连接套筒21对应的位置上设置有第一限位凸块，所述连接套筒21靠近所述安装空间的上端壁的筒壁上设置有第二限位凸块50，通过所述第一限位凸块和所述第二限位凸块50限制所述安装空间的上端壁相对于所述连接套筒21移动的距离。通过设置限位凸块有效地保证了所述安装空间的上端壁相对于连接套筒21的位移量处于可控范围内，防止了第一弹性件和第二弹性件损伤。
从以上的描述中，可以看出，本申请上述的实施例实现了如下技术效果：
由于本申请的脚踏装置包括外壳部和检测部，当骑行者将脚放置脚踏面并施力时，检测部可以直接检测到骑行者施加在所述脚踏面上的脚踏力，从而提供给其他装置骑行者的脚踏力数据，避免了现有技术中通过中置电机的外壳或者中轴的形变检测骑行者施加的力矩，所造成的传递环节过多，容易产生误差累积，检测结果的准确度低的问题。
应该指出，上述详细说明都是例示性的，旨在对本申请提供进一步的说明。除非另有指明，本文使用的所有技术和科学术语具有与本申请所属技术领域的普通技术人员通常理解的相同含义。
需要注意的是，这里所使用的术语仅是为了描述具体实施方式，而非意图限制根据本申请的示例性实施方式。如在这里所使用的，除非上下文另外明确指出，否则单数形式也意图包括复数形式，此外，还应当理解的是，当在本说明书中使用术语“包含”和/或“包括”时，其指明存在特征、步骤、操作、器件、组件和/或它们的组合。

为了便于描述，在这里可以使用空间相对术语，如“在……之上”、“在……上方”、“在……上表面”、“上面的”等，用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。应当理解的是，空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。
例如，如果附图中的器件被倒置，则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而，示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以其他不同方式定位(旋转90度或处于其他方位)，并且对这里所使用的空间相对描述作出相应解释。
在上面详细的说明中，参考了附图，附图形成本文的一部分。在附图中，类似的符号典型地确定类似的部件，除非上下文以其他方式指明。在详细的说明书、附图及权利要求书中所描述的图示说明的实施方案不意味是限制性的。在不脱离本文所呈现的主题的精神或范围下，其他实施方案可以被使用，并且可以作其他改变。将容易理解的是，如本文一般所描述的及附图所图示说明的，本公开的方面可以在广泛种类的不同的配置中被 编排、代替、组合、分开以及设计，所有这些在本文被明确地考虑。
