The invention discloses a power-assisted cart, and the cart comprises a cart frame and at least three wheels arranged on the lower portion of the cart frame and further comprises an electric power-assisted assembly. The electric power-assisted assembly comprises a controller, a power-assisted wheel, a power-assisted driving mechanism used for driving the power-assisted wheel to rotate and a lifting mechanism used for driving the power-assisted wheel to move up and down. The power-assisted driving mechanism and the lifting mechanism are both connected with the output end of the controller, andthe controller is used for sending driving instructions to the power-assisted driving mechanism and the lifting mechanism. Under the driving of the lifting mechanism, the moped wheel can descend untilthe bottom of the moped wheel and the bottom of the wheel are located on the same plane; and under the driving of the power-assisted driving mechanism, the power-assisted wheels can rotate towards the advancing direction of the cart or rotate towards the retreating direction of the cart. The power-assisted driving mechanism of the power-assisted cart is separated from original traveling wheels ofthe cart, and the service life of power-assisted driving is greatly prolonged through a brand-new driving arrangement mode.
本发明公开了一种助力推车,包括车架以及设置在所述车架下部的至少三个车轮,所述助力推车还包括电动助力组件,所述电动助力组件包括控制器、助力车轮、用于驱动所述助力车轮转动的助力驱动机构、用于驱动所述助力车轮上下移动的升降机构;所述助力驱动机构、升降机构均与所述控制器的输出端连接,所述控制器用于向所述助力驱动机构和升降机构发送驱动指令;在所述升降机构的驱动下,所述助力车轮能够下降直至其底部与所述车轮的底部处于同一平面;在所述助力驱动机构的驱动下,所述助力车轮能够向推车前进的方向转动或向推车后退的方向转动。本发明的助力推车的助力驱动机构脱离推车原本的行进轮,全新的驱动设置方式大大延长了助力驱动寿命。
