Latest Patents

One of Jian-Qiu Li's latest patents is an electric wheel assembly applicable for a parallelly mounted dual-tire wheel, axle, and vehicle. This innovative assembly includes a wheel and support axle assembly, an internal-rotor hub motor, a planetary gear reducer, and a brake system. The design features a planetary carrier connected to a hub, which is in turn connected to a spoke and a rim. The wheel support axle passes through a rotor sleeve and is equipped with a hub bearing to support the hub and the entire wheel. The sun gear at the end of the rotor sleeve serves as the power input for the planetary gear speed reducer, while the planetary carrier acts as the power output. This design achieves a relatively high transmission ratio with a compact axial length.

Another notable patent involves a method for diagnosing degradation of a fuel cell stack. This method includes steps for qualitatively determining the degradation type based on the voltage-current curve of the fuel cell stack. It also involves quantitatively measuring parameter values of individual cells and determining the degradation degree of each cell. By assessing the uniformity degradation degree among the cells, the overall condition of the fuel cell stack can be effectively evaluated.
