Publication number: 20200238158Abstract: A method of controlling a four-wheel skateboard, the method comprising: applying a load on an induction switch of the four-wheel skateboard, the induction switch starting a power switch of the four-wheel skateboard; driving the four-wheel skateboard to slide by the assistance of the load; controlling and starting a motor, by a controller of the four-wheel skateboard, to drive the four-wheel skateboard to slide; and taking the load off from the induction switch of the four-wheel skateboard and the induction switch shutting down the power switch of the four-wheel skateboard. The four-wheel skateboard relies on the load-assisted driving, not entirely on the driving force of the motor, so that the four-wheel skateboard consumes less electricity for sliding the same distance as conventional skateboards, requires relatively small amounts of lithium-ion batteries, and requires not too large battery capacity and not too high voltage, thus reducing the manufacturing cost of the four-wheel skateboard.Type: ApplicationFiled: July 30, 2019Publication date: July 30, 2020Inventor: XIAODONG HAN
