The invention relates to the technical field of shopping carts, in particular to a manual-control electric shopping cart capable of avoiding running into people or commodity shelves. An ultrasonic sensor is adopted to detect space in front of the shopping cart, and when an obstacle is found, a driving motor stops running in time, so that the shopping cart is avoided directly running into people orthe commodity shelves. A resistance strain gauge mounted at a handle is adopted to control advancing, leftward turning and rightward turning of the shopping cart; when a user applies a holding force,the user presses down a switch equivalently; when the user stops for shopping, the user automatically presses down a stopping button equivalently, and a consumer does not need to deliberately press aswitch of the driving motor, so that comfort and intelligence of the shopping cart are improved greatly. A pyroelectric infrared sensor circuit is adopted to detect the handle, and only after the consumer is detected and a handle strain gauge is stressed, the driving motor starts to rotate so as to relieve burden of the consumer, so that the phenomenon that the shopping cart runs automatically when the strain gauge fails and no consumer uses the shopping cart is avoided.
