Description

一种电动平衡车及其踏板组件 【技术领域】
本发明涉及平衡车领域，更具体的说，涉及一种电动平衡车及其踏板组件。
【背景技术】
电动平衡车，又称体感车、思维车、摄位车等，目前市场上主要有独轮和双轮两类，其运作原理主要是建立在一种被称为“动态稳定(Dynamic Stabilization，DS)”的基本原理上，利用车体内部的陀螺仪和加速度传感器，来检测车体姿态的变化，并利用伺服控制系统，精确地驱动电机进行相应的调整，以保持系统的平衡。
通常，双轮的电动平衡车主要包括：用于承受用户重量的承重基体、脚踏件、设置于承重基体上的具有一定弹性形变功能的橡胶体，以及设置于承重基体上的光耦开关。用户对脚踏件施加压力后，橡胶体上位于中间的柱体会因压力而向下运动，从而使光耦开关对光线变化进行感应，产生感应信号，控制电动平衡车停车，而当用户撤销上述压力时，橡胶体由于自身弹性回复力作用，中间的柱体会回复到初始位置，从而光耦开关感应光线变化产生另一感应信号，控制电动平衡车继续行进。但是，由于橡胶体本身耐低温能力较差，在零下温度环境中，容易变脆而破碎，无法正常形变，导致电动平衡车无法正常工作。
【发明内容】
本发明所要解决的技术问题是提供一种工作稳定的电动平衡车及其踏板组件。
本发明的目的是通过以下技术方案来实现的：
一种电动平衡车的踏板组件，包括支架，所述支架上部设有摆杆，所述摆杆一端连接金属弹性部件，所述摆杆另一端连接触发件，所述踏板组件还包括 与触发件配合的光耦开关，所述触发件具有向上凸起的驱动部。
本发明由于踏板组件包括支架，支架上设有摆杆，摆杆一端通过金属弹性部件固定，摆杆另一端连接触发件，触发件具有向上凸起的驱动部，当对驱动部施加一个向下的力，触发件向下运动，触发件控制光耦开关进而控制平衡车运动，同时带动摆杆连接触发件一端向下运动，摆杆与金属弹性部件连接一端则向上运动，金属弹性部件产生回复力，当外力消失时，金属弹性部件将摆杆拉回初始位置，初始位置为金属弹性部件将摆杆一端拉下，摆杆另一端则翘起，使摆杆另一端的驱动部处于比其他部件更高的位置，这样踏板组件对温度适应能力较强，不会产生因温度过低而导致的形变缓慢或无法形变的问题，从而保证整个电动平衡车在低温下也能使用，适用更多的地方，适用更冷的天气，结构简单，方便控制。
【附图说明】
