[0002] The design and implementation of motor control systems is an interdisciplinary engineering task involving multiple fields such as power electronics, control theory, motor theory, and computer engineering. Through continuous technological innovation and optimization, the performance and efficiency of motor control systems have been significantly improved, providing strong support for applications in electric vehicles, industrial automation, and household appliances.

[0003] In the prior art, motor power supply control devices are the core part of the motor drive system. They are responsible for converting the power supply (usually a DC power supply) into the AC power required by the motor and controlling the speed and torque of the motor.

[0004] However, most of the existing motor power supply control devices are equipped with cooling fans at the heat dissipation ports for heat dissipation. However, the cooling fans are mostly fixed and can only dissipate heat for control components in a fixed area, resulting in uneven heat dissipation and poor heat dissipation effect of the motor power supply control device. Summary of the invention

[0005] The object of the present invention is to provide a motor power supply control device and a control system to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a motor power supply control cabinet, wherein air outlets are provided in the middle of both sides of the motor power supply control cabinet, air inlets are provided at the upper and lower ends of the air outlets, support blocks are arranged at the inner ends of the air inlet of the motor power supply control cabinet, multiple groups of hinge shafts are arranged between the two groups of support blocks, air guide plates are arranged on the hinge shafts, and the inner middle part of the air guide plates is also connected to the telescopic plate; and a motor power supply control cabinet, wherein a control door panel is provided on the surface of the motor power supply control cabinet, a control component is provided in the inner middle part of the motor power supply control cabinet, and the air outlet and the two groups of air inlets are respectively located at the upper end, the middle part and the bottom end of the control component.

[0009] Preferably, the top of the telescopic plate is connected to a plurality of groups of air guide plates, and the telescopic plate can drive the air guide plates to swing through the hinge shaft by telescoping, so as to evenly disperse the cooling air entering from the air inlet.

[0010] Preferably, the fan shaft is provided with a push plate at the rear end of the heat dissipation blade, the two sets of push plates are parallel and perpendicular to the telescopic plates inserted into the fan assembly at the upper and lower ends, and the push plates can squeeze the telescopic plates to make the telescopic plates telescope up and down.

[0015] A control system comprises the above-mentioned motor power supply control device.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention provides a motor power supply control device and control system. When the motor power supply control cabinet is started by a start button on a control door panel on the surface of the motor power supply control cabinet, the fan shaft in the fan assembly in the middle of both sides of the motor power supply control cabinet starts to drive the heat dissipation blades to rotate, and the heat emitted by the control assembly in the middle of the motor power supply control cabinet is blown out through the air outlet. At the same time, cooling air enters the motor power supply control cabinet from the air inlets at the upper and lower ends of the air outlet, and cools the control door panel in the middle of the motor power supply control cabinet. When the fan shaft rotates, it drives the push plate to start rotating, so that the push plate squeezes the telescopic plate plugged into the fan assembly, so that the telescopic plate drives the air guide plate on the top of the telescopic plate to swing. When the push plate is free from squeezing the telescopic plate, the first springs at the upper and lower ends of the fan assembly pull the connecting plate through the contraction force, so that the connecting plate pulls the telescopic plate again, so that the bottom of the telescopic plate is plugged into the fan assembly, and the air guide plate swings again, so that the cooling air entering the motor power supply control cabinet from the air inlet is evenly dispersed, and uneven heat dissipation of the control assembly is prevented.
