[0002] As a kind of electromechanical equipment that moves vertically, the elevator currently uses the method of dragging the accompanying cable to supply power to the elevator car. The accompanying cable goes up and down with the elevator car, which has the disadvantages of low efficiency and high maintenance costs.
Especially in super high-rise buildings and high-speed elevators, if the elevator running speed is too high or the free suspension length is too long, it will increase the carrying load of the accompanying cables, and there will be safety risks such as wear, accelerated aging, and unsafe exposure, which will greatly reduce the reliability of the elevator. performance and operational efficiency

The invention relates to the technical field of wireless energy transmission, and particularly discloses a wireless power taking type elevator power supply system. The system comprises a transmittingend arranged in an elevator shaft and a picking end arranged on an elevator car. The transmitting end comprises a transmitting guide rail, wherein at least one energy transmission section in the transmitting guide rail is arranged in the movement direction of the elevator car. The picking end comprises a power taking device, wherein the power taking device comprises a receiving coil adapting to the magnetic field distribution of the transmitting guide rail. In the back-and-forth movement process of the elevator car, the power taking device moves along the energy transmission section of the transmitting guide rail, and a receiving coil and the transmitting guide rail keep wireless magnetic coupling all the time. The transmitting guide rail is arranged in the elevator shaft, the power takingdevice corresponding to the transmitting guide rail is arranged on the elevator car, and the transmitting guide rail is arranged according to the working path of the elevator car, so that in the working process of the elevator car, the power taking device and the transmitting guide rail keep wireless magnetic coupling all the time, and energy is obtained to uninterruptedly and continuously supplypower to the elevator car.
