[0030] Conventional electrical control cabinet designs can lead to poor sealing during installation and maintenance, especially in changing environmental conditions such as humid, dusty, or corrosive environments, which can accelerate damage to the control cabinet's sealing structure.

[0031] To this end, the present application provides an electrical control cabinet that can solve the problems existing in the prior art. The technical solutions provided by the present application are described in detail one by one below.

[0032] Figure 1 and Figure 2 This is a structural diagram of an electrical control cabinet according to an embodiment of the present application, which includes a cabinet body 100, a cabinet door 200, and a side panel 300. The cabinet body 100 is made of sheet metal through processes such as stamping, bending, or welding, providing an integrated frame for the entire electrical control cabinet. The cabinet body 100 is provided with openings at the front and both sides. The cabinet door 200 is hingedly mounted at the front of the cabinet body 100. When the cabinet door 200 is closed, the cabinet door 200 can effectively seal the front opening of the cabinet body 100. The openings on both sides of the cabinet body 100 are provided with a first bending portion 110 facing inward on all sides. The end of the first bending portion 110 away from the cabinet body 100 abuts against the inner surface of the side panel 300 on the corresponding side. A first sealed space is formed between the first bending portion 110 and the side panel 300. Second bending portions 310 are provided on all sides of the side panel 300. The outer surface of the second bending portion 310 abuts against the inner surface of the first bending portion 110.

[0033] The openings on both sides of the cabinet 100 abut against the inner surface of the side panel 300 through the first bent portion 110, forming a first sealed space, while the second bent portion 310 of the side panel 300 is tightly fitted with the first bent portion 110. This multi-layered bent structure not only effectively prevents the intrusion of dust and moisture, protecting the safety and stability of the internal electrical components, but also enhances the overall structural strength of the cabinet 100.

[0034] Further, such as Figure 3 and Figure 4 In some embodiments, the bending shape of the first bending portion 110 is a U-shaped structure, and the first bending portion 110 includes a first side section 111, a first middle section 112, and a second side section 113, wherein the first middle section 112 is the bottom of the U-shaped structure, and the first side section 111 and the second side section 113 are the two sides of the U-shaped structure. One end of the first side section 111 is connected to the four sides of the opening on both sides of the cabinet 100, the other end of the first side section 111 is connected to one end of the first middle section 112, the other end of the first middle section 112 is connected to one end of the second side section 113, and the other end of the second side section 113 is against the inner surface of the side panel 300. Figure 4 The second bending portion 310 includes a third side segment 311 and a fourth side segment 312, wherein one end of the third side segment 311 is connected to the four sides of the side panel 300, and the other end of the third side segment 311 is connected to one end of the fourth side segment 312, and the outer surface of the fourth side segment 312 is in contact with the inner surface of the first middle segment 112 in the first bending portion 110. At the same time, the first bending portion 110 and the second bending portion 310 are locked and fixed by a fastening bolt 115, which passes through the first middle segment 112 of the first bending portion 110 and the edge of the side panel 300 in turn to fasten the side panel 300 to the solid. The connection between the side panel 300 and the cabinet body 100 forms a complex sealing interface through the design of a multi-section bending structure, which further improves the sealing performance of the cabinet body 100 and prevents the intrusion of external contaminants.

[0035] In some embodiments, a first sealing strip 114 is further provided between the first bending portion 110 and the second bending portion 310. Figure 4 The first sealing strip 114 has a first slot on one side, and the top end of the second side segment 113 is embedded in the first slot. Meanwhile, the other, opposite side of the first sealing strip 114 is in close contact with the inner surface of the side panel 300. The provision of the first sealing strip 114 provides another layer of sealing protection between the side panel 300 and the cabinet body 100. The first sealing strip 114 is provided in the area where the top end of the second side segment 113 abuts the inner surface of the side panel 300, effectively avoiding the fastening bolts 115. This eliminates the need for the fastening bolts 115 to pass through the first sealing strip 114, thus preventing accelerated aging of the strip due to rusting of the fastening bolts.

[0036] like Figure 3 and Figure 5As shown, in some embodiments, the cabinet door 200 and the front end of the cabinet body 100 are also provided with corresponding bent portions to enhance the sealing performance between the cabinet door 200 and the cabinet body 100. The front end opening of the cabinet body 100 is provided with a third bent portion 120 facing inward on all sides, and the cabinet door 200 is provided with a fourth bent portion 210 on all sides. When the cabinet door 200 is closed, a second enclosed space is formed between the third bent portion 120 and the fourth bent portion 210. The end of the third bent portion 120 away from the cabinet body 100 is against the inner surface of the cabinet door 200, and the outer surface of the fourth bent portion 210 is in contact with the front end of the cabinet body 100. The second enclosed space formed between the third bent portion 120 and the fourth bent portion 210 provides an additional sealing layer. This design effectively prevents dust, moisture and other contaminants from invading the interior of the cabinet body 100 through the cabinet door 200, further improving the sealing performance of the electrical control cabinet.

[0037] Furthermore, in some embodiments, the fourth bending portion 210 includes a fifth side segment 211 and a sixth side segment 212. Figure 5 , wherein one end of the fifth side segment 211 is connected to the cabinet door 200, and the other end of the fifth side segment 211 is connected to one end of the sixth side segment 212. When the cabinet door 200 is closed, the outer surface of the sixth side segment 212 is in contact with the front end of the cabinet body 100; the third bent portion 120 includes a seventh side segment 121, such as Figure 5 One end of the seventh side segment 121 is connected to the front end of the cabinet body 100 , and the other end of the seventh side segment 121 is against the inner surface of the cabinet door 200 .

[0038] Furthermore, in some embodiments, a second sealing strip 122 is provided between the third bending portion 120 and the fourth bending portion 210. Figure 5 A second card slot is provided on one side of the second sealing strip 122, and the second sealing strip 122 is arranged at the top of the seventh side segment 121 through the second card slot. When the cabinet door 200 is closed, the other side of the second sealing strip 122 is close to the inner surface of the cabinet door 200, further enhancing the protection capability of the cabinet door 200.

[0039] like Figure 1 and Figure 6In some embodiments, a heat dissipation structure 320 is provided on the side panel 300. The side panel 300 has heat dissipation holes 321 formed at the mounting location of the heat dissipation structure 320, and the heat dissipation structure 320 covers the heat dissipation holes 321. The heat dissipation structure 320 includes a heat dissipation grille 323 and a heat dissipation fan 322. The heat dissipation grille 323 is mounted on the outer surface of the side panel 300 and consists of multiple inclined blades. These blades are tilted downward from the outer surface of the side panel 300 to prevent rain and dust from directly entering the cabinet 100, providing additional environmental protection and ensuring the safety of internal electrical components. The heat dissipation fan 322 is mounted on the inner surface of the side panel 300. The design of the heat dissipation structure 320, including the heat dissipation grille 323 and the heat dissipation fan 322, significantly improves the heat dissipation capacity of the electrical control cabinet. This design ensures that heat within the cabinet 100 can be quickly dissipated, preventing damage to electrical components caused by excessive internal temperatures.

[0040] It is understood that in some embodiments, the side panels 300 on both sides of the cabinet 100 are each provided with a heat dissipation structure 320, with one heat dissipation structure 320 disposed in the upper region of one side panel 300 and the other heat dissipation structure 320 disposed in the lower region of the other side panel 300. By providing heat dissipation structures 320 on both side panels 300, arranged in the upper and lower regions, respectively, a more uniform heat dissipation layout is formed. This design helps to more effectively dissipate heat from within the cabinet 100, prevent local overheating, and improve overall heat dissipation efficiency.

[0041] like Figure 2 In some embodiments, at least one reinforcement structure 330 is provided on the inner surface of the rear end of the cabinet 100 and the inner surface of the side panels 300. These reinforcement structures 330 enhance the deformation and torsion resistance of these large panels, effectively preventing deformation and twisting caused by external forces during transportation, installation, and use, thereby ensuring the shape stability and overall rigidity of the cabinet 100. These reinforcement structures 330 also provide a mounting rack for the electronic components within the electrical control cabinet, optimizing the utilization of internal space and facilitating the layout and securement of internal components.

[0042] like Figure 1 and Figure 2 In some embodiments, the rear end of the cabinet 100 is further provided with a cable entry hole, the front end of the cabinet 100 is further provided with an operation panel 150, control buttons 130, and an emergency stop button 140, and the cabinet door 200 is further provided with a combination lock 220. The cable entry hole design facilitates the introduction and management of cables, improving the convenience and neatness of installation; the operation panel 150 and control buttons 130 enable users to conveniently operate and monitor the equipment, enhancing ease of use and safety; finally, the combination lock 220 on the cabinet door 200 increases the safety protection of the equipment.

[0043] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application.
