摘要： The motorized wheelbarrow has longitudinally extending frame members, which extend into handle portions. Resting height adjustment of the wheelbarrow is achieved with a pair of tubular legs cooperatively attached to a wheelbarrow support strut and a support strut brace. A wheel is secured proximate the front end of the wheelbarrow to mounting points on a wheel frame. An electric motor is attached to a front portion of the support frame members underneath a load rack or load bucket, depending on the barrow type. A battery is attached under the support frame proximate the motor. A drive mechanism consisting of a chain and sprocket is operably linked to a wheel sprocket and to the electric motor. A disk brake assembly having a disk rotor and caliper is disposed on the wheel and frame for engagement with the wheel and is operably engaged to a control mechanism for safe wheelbarrow stopping.
摘要翻译： 电动手推车具有延伸到手柄部分中的纵向延伸的框架构件。 独轮车的休息高度调节是通过一对管状腿协同地附接到独轮车支撑支柱和支撑支柱支架来实现的。 靠近手推车前端的车轮固定在轮架上的安装点上。 根据手推车类型，电动马达安装在载货架或装载铲斗下方的支撑框架构件的前部。 电池附接在电机附近的支撑架下。 由链条和链轮组成的驱动机构可操作地连接到轮链轮和电动马达。 具有盘转子和卡钳的盘式制动器组件设置在车轮和车架上，用于与车轮接合，并且可操作地接合到用于安全手推车停止的控制机构。
