Technical Field
[0001] This utility model relates to the field of machine room-less elevator technology, and in particular to a machine room-less elevator ceiling-mounted car frame structure. Background Technology
[0002] Machine-room-less elevators refer to elevators that do not require a separate machine room. Their core components, such as the drive unit and control cabinet, are directly installed inside or on the side wall of the shaft. This optimized spatial layout achieves efficient operation. This design breaks away from the traditional elevator's reliance on a separate machine room, offering significant advantages in building adaptability, space utilization, and cost control. It has also driven technological innovation in the elevator industry. Among these, the ceiling-mounted car frame structure is a design where the drive unit and other core components are placed at the top of the shaft. It features high space utilization, a rational layout, and good noise control. However, most existing ceiling-mounted car frame structures have their supports fixed to the top of the shaft, making disassembly inconvenient and hindering regular maintenance. Furthermore, current ceiling-mounted car frame structures have poor ventilation, resulting in slow airflow within the shaft and affecting passenger comfort.
