[0074] In order to make the purpose, scheme and advantages of the technical scheme of the utility model more clear, the technical scheme of the utility model embodiment will be described clearly and completely in the following by combining the drawings of the specific embodiment of the utility model. Unless otherwise specified, the terms used herein have the usual meanings in the art. The same reference numerals in the drawings represent the same components.

[0075] Figure 1A schematic diagram of an elevator system 100 according to a first embodiment of the present application is shown, which mainly comprises a guide rail 110, a car (not shown) and a motor 120. The guide rail 110 can extend in a vertical direction, for example, to serve as a track for the car to travel in the vertical direction. The car moves along the guide rail 110 to transport passengers in the car, for example, from the 1st floor to the 10th floor of a building. The motor 120 is configured to drive the car to move along the guide rail 110, for example, an output shaft of the motor 120 can be connected to the car via a transmission system.

[0076] As shown in Figure 2 The motor 120 is provided with motor mounting holes 122, 124 for fixing the motor 120 to the guide rail 110. The motor can need to be replaced due to reaching the service life or the like, however, during the replacement operation of the motor, because the new motor 120 can have a different model from the old motor (not shown), the new motor 120 cannot be directly mounted to the guide rail 110 as the old motor. For example, the positions of the mounting holes of the new motor 120 can be different from the positions of the mounting holes of the old motor, in the case that the mounting holes of the old motor are aligned with the fastening holes of the guide rail 110, the mounting holes of the new motor 120 are no longer completely aligned with the fastening holes of the guide rail 110, causing the misfit between the new motor 120 and the guide rail 110.

[0077] To improve the misfit problem between the new motor 120 and the guide rail 110 described above, the elevator system 100 proposed by the present disclosure further comprises an adapter plate 130, which is arranged between the motor 120 and the guide rail 110, the adapter plate 130 is fixed to the guide rail 110 and the motor 120 respectively, so that the motor 120 is fixed to the guide rail 110 via the adapter plate 130.

[0078] Optionally, the adapter plate 130 can comprise a first upper assembly hole 134-U located at its upper portion and a first lower assembly hole 134-L located at its lower portion, the first upper assembly hole 134-U and the first lower assembly hole 134-L are respectively aligned with the upper mounting hole 122 located at the upper portion of the motor 120 and the lower mounting hole 124 located at the lower portion of the motor 120, a fastener (e.g., a screw) passes through the first upper assembly hole 134-U and the upper mounting hole 122 to achieve the fixation between the upper portion of the motor 120 and the adapter plate 130, a fastener (e.g., a screw) passes through the first lower assembly hole 134-L and the lower mounting hole 124 to achieve the fixation between the lower portion of the motor 120 and the adapter plate 130.

[0079] Optionally, the adapter plate 130 can include a second upper assembly hole 136-U at its upper portion and a second lower assembly hole 136-L at its lower portion, the second upper assembly hole 136-U and the second lower assembly hole 136-L are aligned with the upper fastening hole 112 at the upper portion of the rail 110 and the lower fastening hole 114 at the lower portion of the rail 110 respectively, a fastener (e.g., a screw) passes through the second upper assembly hole 136-U and the upper fastening hole 112 to achieve the fixation between the upper portion of the rail 110 and the adapter plate 130, and a fastener (e.g., a screw) passes through the second lower assembly hole 136-L and the lower fastening hole 114 to achieve the fixation between the lower portion of the rail 110 and the adapter plate 130.

[0080] Optionally, the first lower assembly hole 134-L can coincide with the second lower assembly hole 136-L, and a fastener passes through the lower fastening hole 114, the first lower assembly hole 134-L (also the second lower assembly hole 136-L) and the lower mounting hole 124 in sequence to fix the motor 120 to the rail 110 via the adapter plate 130. In other words, the holes configured to fix the lower portion of the adapter plate 130 to the lower portion of the rail 110 can be the same holes as the holes configured to fix the lower portion of the adapter plate 130 to the lower portion of the motor 120. Alternatively, the elevator system 100 can also be designed such that the first upper assembly hole coincides with the second upper assembly hole, and a fastener passes through the upper fastening hole 112, the first upper assembly hole (also the second upper assembly hole) and the upper mounting hole in sequence to fix the motor 120 to the rail 110 via the adapter plate 130. It should be understood that although the above describes that the holes with the dual function of being fixed to the rail 110 and being fixed to the motor 120 can be provided at the upper portion or the lower portion of the adapter plate 130, the present disclosure is not intended to be limited thereto, and neither the upper portion nor the lower portion of the adapter plate 130 can be provided with the holes with the above-mentioned dual function.

In addition to the way of fastening the fastener through the guide rail fastening hole 212, 214 and the second assembly hole 236-U, 236-L, the fixing between the adapter plate 230 and the guide rail 210 can also be achieved by the clamp 240. It should be understood that the present disclosure is not intended to limit the specific fixing way between the adapter plate 230 and the guide rail 210, and the adapter plate 230 and the guide rail 210 can be fixed by screws, clamps or a combination of screws and clamps and any other suitable way.

[0083] Specifically, as shown in Figure 4 The clamp 240 has a fastening part 242 fixed to the adapter plate 230 and a clamping part 244 configured to clamp the guide rail 210. For example, the fastening part 242 can be fixed to the adapter plate 230 through the fitting hole 238.

[0084] In addition, as shown in Figure 5 The adapter plate 230 can include a main body 231 and a widened part 232 located above the main body 231 and having a wider width than the main body 231. The fitting hole 238 and the second upper assembly hole 236-U are located in the widened part 232, and the first upper assembly hole 234-U is located in the main body 231. The fitting hole 238 can be located outside the second upper assembly hole 236-U, so that the fastening part 242 of the clamp 240 is fixed to the outside of the widened part 232 of the adapter plate 230, thereby facilitating the clamping part 244 of the clamp 240 to extend inwardly from the fastening part 242 to clamp the guide rail 210.
