The invention discloses an intelligent power-assisted cart which comprises a frame with wheels mounted at the bottom and a power-assisted system, a handle for pushing the cart is arranged on the frame, and the handle is rotatably connected with the frame. The power assisting system comprises a detection device used for detecting the rotating angle and direction of the handle relative to the frame, a control device and a driving device used for driving the intelligent power assisting cart, the detection device is connected with the input end of the control device, and the output end of the control device is connected with the input end of the driving device; and the control device controls on-off and/or driving speed and/or driving direction of the driving device according to the rotating angle and direction information of the handle detected by the detection device. By detecting the rotating angle and direction of the handle relative to the frame, the direction and the size of the assisting force needing to be provided can be directly judged, the structure and an assisting system are simpler, the manufacturing cost is low, and installation and maintenance are convenient.
本发明公开了一种智能助力推车,包括底部安装有车轮的车架以及助力系统,车架上设有用于推动推车的把手,把手与车架可转动连接,助力系统包括用于检测把手相对于车架转动的角度和方向的检测装置、控制装置和用于驱动智能助力推车的驱动装置,检测装置与控制装置的输入端连接,控制装置的输出端与驱动装置的输入端连接;控制装置根据检测装置检测到的把手转动的角度和方向信息来控制驱动装置的开关和/或驱动速度和/或驱动方向。本发明通过检测把手相对于车架转动的角度和方向,则可直接判断出需要提供助力的方向和大小,其结构和助力系统更简单,制造成本低且方便安装和维修。
