Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, for clarity and brevity, the description of known functions and structures has been omitted.

[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other.

[0028] It should be understood that self-driven rail elevators use driving wheels to travel on guide rails to drive the car to move up and down, and can be used in buildings such as villas. The application scenarios of such small elevator equipment are often very limited in space. Therefore, it is necessary to consider reducing the hoistway space occupied by the elevator during design. If the hoistway space is arranged compactly to improve the utilization rate of the hoistway space, the space around the car in the hoistway will be narrow, and it will be very inconvenient to disassemble and assemble the car-related structures from the outside of the car. To this end, the present application provides a car frame that improves the convenience of installing and disassembling the car, which is described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, the car frame includes a car base 10 and a rear seat bracket 30. The car base 10 is used to form the bottom of the car space, and the rear seat bracket 30 is located at the rear side of the car base 10. The rear seat bracket 30 is provided with a guide wheel 32, which is used to guide and limit the movement of the rear seat bracket 30 along the guide rail 50.

[0030] Specifically, the inner space between the car bottom and the car top is the car space, which is used to accommodate people and objects to be transported. Figure 2As shown, the inside of the periphery of the car platform is the inside IN of the car platform, and the inside IN of the car platform is located in the car space. The rear seat bracket 30 is located between the car platform 10 and the guide rail 50, and the guide wheel 32 thereon can guide and limit the movement of the rear seat bracket 30 along the guide rail 50. The rear seat bracket can be provided with guide wheels in multiple directions, and the guide wheels in multiple directions together limit the rear seat bracket on the guide rail. The car platform 10 is fixed on the rear seat bracket, and then the rear seat bracket is raised and lowered together.

[0031] In a self-driven rail elevator, the car frame is used to connect with a driving device, which includes a driving wheel and a driving source.
