图2为底盘前部设置不可变向行走系统的电动割草机结构图；
图3为把手装置结构示意图；
图4为后盖板在最大打开状态下结构示意图；
图5为后盖板在最小打开状态下结构示意图。
具体实施方式
如图1至图5所示，一种电动割草机，包括机体1，所述机体包括底盘10，所述底盘10上设有行走装置、割草装置、动力装置2、把手装置3、后排草装置4，所述动力装置2驱动行走装置及割草装置工作，所述后排草装置4将割草 装置割出的草排出，所述把手装置3对电动割草机进行控制。
其中，如图2所示，所述动力装置采用直流电源和交流电源组成的混合动力系统，驱动控制板21对混合动力进行驱动控制，所述直流电源采用电池包20，所述交流电源包括变压器23及整流器，变压器23及整流器将交流电转换为电压与电池包20相等的直流电为电机22供电。
在只插入电池包20的情况下开机，驱动控制板21会检测到供电来自于电池包20而启动电机22，当只接入交流电时，驱动控制板21会将交流电转化为电压与电池包20相等的直流电，再经过驱动控制板21后启动电机22。
如图1和图2所示，所述行走装置包括设于底盘10上的前轮组件11和后轮组件12。
如图1所示，前轮组件11为万向轮行走系统，包括三轮前底盖111和安装在三轮前底盖上的万向轮112，三轮前底盖111固定在底盘10上，后轮组件为不可变向行走系统，万向轮行走系统和不可变向行走系统组成一个系统，推行时转向灵活。
如图2所示，前轮组件11为不可变向行走系统，包括四轮前底盖113和安装在四轮前底盖上的双轮114，四轮前底盖113固定在底盘10上，这是传统割草机的结构，推行可以变向但不方便，后轮组件为万向轮行走系统。
四轮前底盖113、双轮114组成的前轮组件11与三轮前底盖111、万向轮112组成的前轮组件11可以互换结构安装在底盘上，可以实现两个系统的快换。
如图3所示，所述把手装置包括上把手34与下把手31，所述上把手34与下把手31之间设有把手调节机构，所述把手调节机构包括调节面板301，调节面板由上面板和下面板38组合而成(图中所示是将上面板去掉后结构)，在下面板38上设有销轴定位座32，销轴定位座32上设有销轴39，在下把手31上 设有销孔，在上把手上设有档位孔，(上把手上设有多个档位孔，每个档位孔都对应一个档高度)。所述销轴39在压簧36作用下通过销孔插入档位孔。
所述销轴39由按钮37进行控制，所述按钮37与销轴39之间设有驱动块35，所述驱动块上设有斜楔面，所述按钮37与斜楔面作用驱动销轴与上把手34上的档位孔脱开。
所述上把手下端设有上套管33，所述下把手上端设有下套管30，下套管内套于上套管内，当销轴达到最高档时，下套管顶住上套管。
如图3所示，操作者按下按钮37，按钮37的两端面作用到2个驱动块35的斜楔面上，给驱动块35一个沿销轴39轴向的力，使得2个驱动块35沿着销轴39的轴线方向向中间移动，并压缩压簧36，进一步的讲，当按钮37按到底时，销轴39与上把手34脱开。进一步的讲，当销轴39与上把手34完全脱开后，操作者可以上拉或者下压上把手34，然后松开按钮37，按钮37在压簧36的作用下复位，销轴39在压簧36的压力下顶住上把手34，继续上拉或下压上把手34，当销轴39对应到相应的档位孔后，压簧36迅速顶着销轴39插进上把手34的档位孔，已达到要调节的高度档。
进一步的讲，当销轴39已经达到最高档的位置时候，下套管30顶住上套管33，以防止将上、下把手分离。
如图4和图5所示，所述后排草装置4包括设于后排草口上的后盖板41，所述后盖板上侧与机壳43铰接，所述后盖板41与机壳43之间设有调节后盖板41角度的后盖板调节机构。
