[0018] Please see Figure 1 and Figure 2 A preferred embodiment of this application shows a split elevator main control cabinet including at least one of an ARD cabinet, a control cabinet, and a frequency converter cabinet. When any two of the ARD cabinet, control cabinet, and frequency converter cabinet are assembled, they are connected by at least one connecting bracket and bolts.

[0019] According to the embodiment of this utility model, the main control cabinet is divided into three cabinet units: ARD cabinet, control cabinet and frequency converter cabinet. Customers can freely combine the cabinets according to their own needs. It also supports various installation methods such as installation inside and outside the shaft and separate installation, making the installation more flexible and convenient and the product more applicable.

[0020] The following detailed description uses specific examples:

[0021] This split-type elevator main control cabinet is made of waterproof materials and processed with high-toughness steel. The ARD cabinet, comprising a lithium battery and an ARD board, is a unit specifically designed to provide emergency rescue in the event of a power outage or malfunction. When the elevator suddenly stops due to a power supply system failure or hardware / software malfunction, the ARD will automatically start within a short time, ensuring safety by moving the elevator to the pre-set leveling position and opening the car door to allow passengers to escape safely. The control cabinet includes a main control board and interface boards, providing functions such as elevator logic control, communication between system modules, signal acquisition, output control, emergency stop, brake release, and lighting switching operations, elevator system detection signal input, power input and distribution, and safety circuit signal serialization. The frequency converter cabinet includes a drive board, a DSP control board, and a brake power supply board. The drive board provides power to the traction machine, enabling variable frequency speed control of the motor; the DSP board controls motor performance; and the brake power supply board provides power for the system's control, safety circuits, and brake.

[0022] Please see Figure 1In one embodiment, the split-type elevator main control cabinet includes three cabinets: an ARD cabinet, a control cabinet, and a frequency converter cabinet. The control cabinet is located on the side of the frequency converter cabinet, and the ARD cabinet is located on top of the control cabinet and connected to the side of the frequency converter cabinet. The control cabinet and the bottom of the frequency converter cabinet are connected by a first connecting bracket, and the ARD cabinet and the top of the frequency converter cabinet are connected by a first connecting bracket. The two contacting surfaces of the three cabinets are fixed with bolts to make the assembly more stable. The first connecting bracket is a planar structure. In this embodiment, each side of the first connecting bracket has a pair of holes. Two holes on one side of the first connecting bracket located at the top of the frequency converter cabinet are fixed to the ARD cabinet with bolts, and two holes on the other side are fixed to the frequency converter cabinet with bolts. Two holes on one side of the first connecting bracket located at the bottom of the frequency converter cabinet are fixed to the control cabinet with bolts, and two holes on the other side are fixed to the frequency converter cabinet with bolts.

[0023] Please see Figure 2 In one embodiment, the split-type elevator main control cabinet includes two cabinets: a control cabinet and a frequency converter cabinet. The control cabinet is located on the side of the frequency converter cabinet. The bottom of the control cabinet and the frequency converter cabinet are connected by a first connecting bracket, and the top of the control cabinet is connected to the side of the frequency converter cabinet by a second connecting bracket. The two contacting surfaces of the control cabinet and the frequency converter cabinet are fixed together with bolts. In this embodiment, the second connecting bracket has an L-shaped structure, which can better fix the top of the control cabinet and the side of the frequency converter cabinet.

[0024] Please see Figure 1 and Figure 2 The ARD cabinet, control cabinet, and frequency converter cabinet each have several pre-drilled fixing holes on their backs. When the cabinets are installed separately, they can be fixed to the wall using expansion screws and bolts. Specifically, in this embodiment, the ARD cabinet has one pre-drilled fixing hole on its back, the frequency converter cabinet has one pre-drilled fixing hole at each of the four corners of its back, and the control cabinet has three pre-drilled fixing holes on its back, two at the bottom and one at the top.

[0025] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0026] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
