[0026] Please refer to Figure 1 to Figure 2 A new energy machine room-less elevator is shown in a preferred embodiment of the present application, and the new energy machine room-less elevator includes an elevator car 2, a drive module 3 and a power supply module.

[0027] The elevator car 2 is arranged in the hoistway 1, and the hoistway 1 is a concrete structure or a steel structure.

[0028] The driving module 3 connects the shaft 1 and the elevator car 2 to drive the elevator car 2 to move up and down in the shaft 1, wherein the driving module 3 includes a motor, a reducer, a braking device, a guide rail system, etc. The motor is the power source of the elevator, and usually an AC or DC motor is used. The elevator car 2 is moved up and down in the shaft 1 by controlling the operation of the motor. The reducer is used to reduce the speed of the motor, increase the torque output, and convert the rotational motion into linear motion to drive the elevator car 2 up or down. The braking device is used to control the stop and holding position of the elevator to ensure that the elevator remains stable when it stops at a floor; the guide rail system is a system used to support and guide the movement of the elevator car 2, including guide rails, guide rail brackets and other components to ensure the safe operation of the elevator car 2 in the shaft 1. It is a prior art and will not be described in detail here.

Specifically, the energy storage unit 4 is arranged at the top of the shaft 1, and a part of it is located directly above the elevator car 2. The inverter unit 6 is arranged on the side wall of the shaft 1. The energy storage unit 4 and the inverter unit 6 are placed in the shaft 1 to reduce damage caused by external factors and provide safe and stable operation of the elevator.

Specifically, the longitudinal direction of the energy storage unit 4 is horizontally extended along the top of the well 1, and the longitudinal direction of the inverter unit 6 is vertically extended along the well 1. Such an arrangement can save the building installation space to the maximum extent. Of course, the longitudinal directions of the energy storage unit 4 and the inverter unit 6 can also extend in other directions, which can be adjusted according to the positions of the energy storage unit 4 and the inverter unit 6, and are not specifically limited here.

[0035] In this embodiment, the new energy power generation unit 5 is any one or more combinations of photovoltaic power generation components, wind power generation units and tidal power generation components. Of course, the new energy power generation unit 5 can also be other types, such as geothermal power generation systems, biomass power generation systems, etc., which are existing technologies and can be selected according to actual conditions, and are not specifically limited here.

[0036] In this embodiment, the new energy machine room-less elevator further includes a control module, which is electrically connected to the drive module 3 and the power supply module to control the operation of the drive module 3 and the power supply module.

[0037] Specifically, the control module includes a control unit arranged in the shaft 1 and a floor control component respectively arranged at each floor and the elevator car 2. The control unit is electrically connected to the floor control component, wherein the control unit includes an elevator controller, a sensor, an encoder and other equipment for monitoring and controlling the operating status of the elevator to achieve precise floor stopping and operation control. The floor control component includes floor buttons, floor display screens, etc., which are used to send feedback signals to the control unit and display floor information to the user. This is a prior art and will not be described in detail here.
