[0072] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0073] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0077] Heating, ventilation, and air conditioning (HVAC) systems are used to regulate the indoor environment, including functions such as heating, ventilation, and air conditioning. Their main purpose is to provide users with a comfortable and healthy indoor environment by controlling parameters such as temperature, humidity, and airflow. Common HVAC equipment includes air conditioners, radiators, and ventilation systems. These devices are widely used in residential, commercial buildings, and industrial settings.

[0078] Taking HVAC equipment as an example, an air conditioning system can be a multi-split system for buildings, that is, multiple indoor units are connected in parallel with one or more outdoor units to form a refrigerant circuit so that the refrigerant can circulate. Figure 1 and Figure 2 The diagram shows the outdoor unit P of the air conditioning system. Outdoor unit P has a casing 200, inside which are housed a compressor, switching valve, outdoor heat exchanger, outdoor expansion valve, and oil separator, etc. These components are connected by refrigerant piping. Additionally, an air supply fan 300 is installed in outdoor unit P.

[0079] Furthermore, the outdoor unit P also includes an electrical control box 100. The housing 200 is the external structure of the HVAC equipment, protecting internal components, providing a mounting base, and optimizing airflow. The housing 200 can be made of metal or high-strength plastic, possessing good mechanical strength and corrosion resistance. The housing 200 can be rectangular and placed on the roof or ground. The housing 200 isolates internal live components from the outside environment, preventing direct contact by users and reducing the occurrence of electric shock and other safety accidents. The electrical control box 100 is the core control component in the HVAC equipment. Installed inside the housing 200, the electrical control box 100 facilitates maintenance and replacement, and also simplifies the installation and layout of the overall HVAC equipment structure. The electrical control box 100 is responsible for the precise control of the HVAC equipment's operation. It is equipped with various control circuits, using various electronic components and wiring to achieve control functions for the HVAC equipment, including starting, stopping, temperature adjustment, and mode switching.

[0080] The housing 200 provides protection for the electronic components inside the control box 100, preventing dust, moisture, oil, and other external impurities from entering. It also protects the control box 100 from extreme environmental conditions (such as temperature, humidity, and chemical corrosion), ensuring normal operation in various environments and extending the lifespan of the control box 100. The control box 100 contains high-voltage circuits and live components; housing them within the housing 200 prevents accidental contact by users, reducing the risk of electric shock and improving safety. Furthermore, the housing 200 also acts as shielding, reducing the impact of external electromagnetic interference on the electronic components inside the control box 100, ensuring the stability and reliability of the control system.

[0081] like Figure 1 and Figure 2 As shown, in this embodiment, the housing 200 is rectangular, while the electrical control box 100 has a length direction, which is arranged along the height direction (i.e., the vertical direction) of the housing 200. Therefore, the internal structure of the electrical control box 100 has a vertical arrangement. This vertical length arrangement can better meet the overall structural layout requirements of the equipment when the housing 200 has a large height and limited horizontal space, and is also conducive to heat dissipation and maintenance operations.

[0082] It should be noted that the present invention is not limited to the arrangement of the control box 100 along the height direction of the housing 200 in the above embodiments. In other embodiments, the control box 100 may also be arranged along the length direction of the housing 200, or the control box 100 may be arranged along the width direction of the housing 200. Furthermore, the control box 100 may not be a single form extending along the length direction; it may also vary according to the internal space of the housing 200, for example, it may be formed into an approximate "L" shape, "T" shape, etc.

[0083] In some embodiments, an air duct is formed within the housing 200. This air duct guides air to flow along a predetermined path, preventing disordered airflow within the housing 200 and thus improving heat dissipation efficiency. Specifically, as exemplarily shown in the figure, the air supply fan 300 is located at the top of the housing 200, i.e., at the top of the air duct, and blows air upwards. Furthermore, the electrical control box 100 is located within the air duct, thus utilizing the airflow within the air duct to remove the heat generated by the electrical control box 100, ensuring effective heat dissipation of the electrical control box 100.

[0084] Please continue reading. Figure 1 and Figure 2 In some embodiments, the housing 200 is provided with a maintenance opening 200a. In one configuration, the housing 200 is rotatably connected to an inspection door 200b, allowing maintenance personnel to expose the maintenance opening 200a by opening the inspection door 200b. In another configuration, the housing 200 is detachably connected to the inspection door 200b via bolts or other components, allowing maintenance personnel to separate the inspection door 200b from the housing 200 by removing the bolts or other components, thereby exposing the maintenance opening 200a. This application does not impose specific limitations on the manner in which the maintenance opening 200a is exposed.

[0085] At least a portion of the electrical control box 100 is located at the maintenance port 200a, allowing maintenance personnel to quickly locate the electrical control box 100 without having to extend excessively into the housing 200, thus greatly improving the efficiency of maintenance and repair.

[0086] Figure 3 A schematic diagram of the electrical control box in one or more embodiments of this application is shown. Figure 4 It shows Figure 3 An explosion diagram. Please refer to... Figure 3 and Figure 4In some embodiments, the electrical control box 100 includes a first box body 110, a support frame 120, and a main control module 130. A first cavity 111 is formed inside the first box body 110. The support frame 120 is connected to the first box body 110 and arranged inside the first cavity 111. The main control module 130 includes a main control board 131 and a main control power board 132 that are electrically connected. The main control board 131 and the main control power board 132 are respectively disposed on opposite sides of the support frame 120, so that the main control board 131 and the main control power board 132 are stacked inside the first cavity 111.

[0087] The electrical control box 100 provided in this application, with the main control board 131 and the main power supply board 132 respectively located on opposite sides of the support frame 120, allows the main control board 131 and the main power supply board 132 constituting the main control module 130 to be stacked within the first cavity 111. Compared to the traditional flat arrangement, the stacked arrangement utilizes the vertical space of the electrical control box 100, saving horizontal installation space and making the internal layout of the electrical control box 100 more compact. For HVAC equipment requiring miniaturization, on the one hand, the saved installation space allows the electrical control box 100 to be installed in smaller HVAC equipment; on the other hand, the reduction in the size of the electrical control box 100 reduces the overall size of the HVAC equipment, thereby reducing material usage and lowering production costs.

[0088] Figure 5 It shows Figure 3 A front view diagram. For ease of description, the electrical control box is now defined to have a height direction, a width direction, and a depth direction, where the height direction is... Figure 5 The vertical direction and the width direction are shown. Figure 5 The left and right directions are shown, and the depth direction is... Figure 5 The front-to-back direction is shown. The specific details of the electrical control box 100 will now be further described with reference to the accompanying drawings.

[0089] In this embodiment, the electrical control box 100 uses a first box body 110 as its main frame, and a first cavity 111 is formed inside the first box body 110. The first box body 110 can be made of high-strength insulating engineering plastic or metal alloy material, such as polycarbonate (PC) or aluminum alloy. The shape of the first cavity 111 can be various, such as regular shapes like rectangles or circles, or irregular shapes like polygons, specifically designed according to the layout and installation requirements of the main control module 130 inside the first box body 110, thereby providing adaptation space for the subsequent installation of the main control module 130. For example, the first cavity 111 in this embodiment is roughly rectangular.

[0090] To facilitate the maintenance of the main control module, at least a portion of the first cavity 111 inside the first housing 110 of this application faces the maintenance port 200a. After maintenance personnel open the maintenance door to expose the maintenance port 200a, they can directly inspect and maintain the main control module 130 inside the first cavity 111 through the maintenance port 200a, thereby improving maintenance efficiency.

[0091] Combination Figure 4 The first box 110 has an inspection port 112, which is connected to the first cavity 111. At least part of the inspection port 112 is opposite to the maintenance port. After the maintenance personnel open the inspection door b to expose the maintenance port, they can directly inspect and maintain the main control module 130 in the first cavity 111 through the inspection port 112, so as to improve the maintenance efficiency.

[0092] It should be noted that, in this application, "at least part of the inspection port 112 is opposite to the maintenance port" means that the entire inspection port 112 is opposite to the maintenance port; or, a part of the inspection port 112 is opposite to the maintenance port, for example, the lower space of the inspection port 112 is opposite to the maintenance port, and the upper space of the inspection port 112 is located above the maintenance port. This application does not impose any restrictions on this.

[0093] In some embodiments, the main control power board 132 and the main control board 131 are stacked in the first cavity 111 along the opening direction of the inspection port 112. The main control power board 132 is electrically connected to the main control board 131 and is used for high-voltage power access and to provide a stable power supply to the main control board 131.

[0094] Considering the safety hazards during maintenance of the main control module 130, in some embodiments, the main control board 131 and the main control power board 132 are stacked along the depth direction of the first cavity 111. The main control board 131 is closer to the maintenance port 112 than the main control power board 132, that is, the main control board 131 is located outside the main control power board 132, so that maintenance personnel can more conveniently and quickly maintain the main control board 131 and improve maintenance efficiency. In actual operation, the main control power board 132 is connected to high-voltage lines, which poses a high risk of electric shock; while the main control board 131 processes low-voltage signals and is relatively safer. Through the layered layout, when performing wiring operations, maintenance personnel directly face the interaction module 1311 of the main control board 131, and only come into contact with low-voltage signals, effectively avoiding direct contact with high-voltage lines and improving the safety of the electrical control box 100 during operation.

[0095] Meanwhile, the main control board 131 and the main control power board 132 are stacked and spaced apart, which can reduce the impact of electromagnetic interference generated by the main control power board 132 on the main control board 131 and improve the stability and accuracy of the signal.

[0096] Combination Figure 4In some embodiments, the electrical control box 100 further includes a first cover 140, which is connected to the first box body 110 and detachably covers the access port 112. When the electrical control box 100 is not under maintenance, the first cover 140 seals the access port 112, so that the first cavity 111 inside the first box body 110 is in a sealed environment. The main control module can operate in a protected environment, preventing the main control module inside the first cavity 111 from being corroded by external environmental factors (such as wind, dust, rain, and snow), reducing the risk of damage to the main control module 130, and improving the service life of the main control module 130.

[0097] Figure 6 An assembly diagram of the first cover 140 and the first box 110 is shown. Figure 7 An exploded view of the first cover 140 and the first box 110 is shown. Figure 6 and Figure 7 The second box is omitted, combined with Figure 6 as well as Figure 7 In some embodiments, the first cover 140 is rotatably connected to the first housing 110, meaning the first cover 140 can be opened by flipping it. Specifically, the control box 100 also includes a rotating shaft 150 and a first connecting post 151. The rotating shaft 150 and the first connecting post 151 are respectively disposed opposite to each other outside the first housing 110. One side of the first cover 140 is rotatably connected to the rotating shaft 150, and the other side of the first cover 140 is detachably connected to the first connecting post 151. When maintenance personnel need to open the first cover 140, they first disconnect the first cover 140 from the first connecting post 151, then flip the first cover 140 to expose the inspection port 112, allowing maintenance personnel to inspect and maintain the main control module 130 inside the first cavity 111.

[0098] Combination Figure 6 And 7, the top of the first box 110 extends to a first plate 113, the first plate 113 is roughly on the same plane as the access port 112, a mounting hole 114 is opened on the first plate 113, the rotating shaft 150 can be fixedly or rotatably connected to the first plate 113 and located in the mounting hole 114, the axis of the rotating shaft 150 is in the horizontal direction shown in the figure, a bushing 141 is provided on one side of the first cover 140, the bushing 141 is rotatably connected to the rotating shaft 150, so that one side of the first cover 140 is rotatably connected to the rotating shaft 150.

[0099] Combination Figure 6 as well as Figure 7A second plate 115 extends from the bottom of the first housing 110. The second plate 115 is approximately on the same plane as the side of the first housing 110 away from the access port 112. The second plate 115 can be integrated into the cold plate body 170 described below. A first connecting post 151 is fixedly connected to the second plate 115. The axis of the first connecting post 151 is perpendicular to the axis of the rotating shaft 150. The axis of the first connecting post 151 is arranged along the stacking direction of the main control board 131 and the main control power board 132. A connecting plate 142 is provided on the other side of the first cover 140. The connecting plate 142 is detachably connected to the first connecting post 151 by screws. When maintenance personnel need to open the first cover 140, they first loosen the screws connecting the connecting plate 142 to the first connecting post 151 to disconnect the first cover 140 from the first connecting post 151. Then, they flip the first cover 140 to expose the access port 112.

[0100] Figure 8 A schematic diagram of the structure of the first cover 140 is shown, combined with Figure 7 as well as Figure 8 A support member 143 is provided on the inner side of the first cover 140 and extends toward the main control cover 160 (hereinafter referred to as the main control cover). The support member 143 is used to cooperate with the limiting member 164 on the main control cover 160 (hereinafter referred to as the main control cover) so that the first cover 140 can be suspended when opened, so as to facilitate maintenance personnel to perform maintenance work. For example, the support member 143 can be integrally formed with the first cover. There are two support members 143. The two support members 134 are respectively provided on the edge of the first cover 140 facing the bushing 141. The two support members 143 are respectively inserted at the two corners of the first cavity 111 facing the rotating shaft 150, so as to avoid the support member 143 occupying the central space of the first cavity 111 and avoiding interference with the maintenance personnel's maintenance work. As for the technical solution of how the support member 143 cooperates with the limiting member 164 on the main control cover 160 (hereinafter referred to as the main control cover) so that the first cover 140 can be suspended when opened, please refer to the relevant description below, which will not be repeated here.

[0101] The support frame 120 of this application is a mounting carrier for the main control board 131 and the main control power board 132 within the first cavity 111. The support frame 120 ensures the stability of the stacking position and electrical connection between the main control power board 132 and the main control board 131. Along the stacking direction from the main control board 131 to the main control power board 132 (i.e., the front and rear sides of the support frame 120), the support frame 120 needs to maintain a certain distance from the inner wall of the first cavity 111 so that the main control board 131 and the main control power board 132 can be installed between the inner wall of the first cavity 111 and the support frame 120.

[0102] Figure 9 An assembly diagram of the support frame 120 and the first housing 110 is shown. Figure 10 It shows Figure 9 An explosion diagram. Figure 11 A structural schematic diagram of the support frame 120 is shown. (Combined with...) Figures 9-11 In some embodiments, the control box 100 further includes a connecting ear plate 121, which is connected to the edge of the support frame 120; the first cavity 111 has a support wall 1111 (the inner part of the cold plate body 170 hereinafter), the support wall 1111 and the support frame 120 are arranged opposite to each other, and the support wall 1111 is connected to a second connecting post 1112, which supports and connects the connecting ear plate 121. With this arrangement, the support frame 120 can be suspended in the first cavity 111 by the support of the second connecting post 1112, so that there is a certain distance between the support frame 120 and the inner wall of the first cavity 111, providing space for the installation of the main control board 131 and the main control power board 132.

[0103] In specific implementation, the support wall 1111 and the inspection port 112 are arranged opposite to each other. The second connecting column 1112 is integrally formed on the inner side of the support wall 1111. The end of the second connecting column 1112 is provided with a first connecting hole 1113. The connecting ear plate 121 is also integrally formed with the support frame 120. The connecting ear plate 121 is provided with a second connecting hole 1211. The second connecting column 1112 supports the connecting ear plate 121. The first connecting hole 1113 and the second connecting hole 1211 are arranged opposite to each other. Thus, the connecting ear plate 121 can be fixed on the second connecting column 1112 by screws or other connecting parts that pass through the first connecting hole 1113 and the second connecting hole 1211, so that the support frame 120 is suspended in the first cavity 111.

[0104] It should be noted that the height of the second connecting column 1112 is about half the depth of the first cavity 111 (in the direction from the support wall 1111 to the access port 112), so that there is enough space between the support frame 120 and the support wall 1111 to assemble the main control power board 132, and there is also enough space between the support frame 120 and the access port 112 to assemble the main control board 131.

[0105] To facilitate the assembly of the support frame 120, the connecting ear plate 121 of this application is also provided with a first positioning hole 1212, and the support wall 1111 is also connected with a positioning post 1114, which passes through the first positioning hole 1212. When assembling the support frame 120, the first positioning hole 1212 on the connecting ear plate 121 is penetrated by the positioning post 1114, and the connecting ear plate 121 moves along the direction of the positioning post 1114 until the connecting ear plate 121 is supported by the second connecting post 1112. Then, the connecting ear plate 121 and the second connecting post 1112 are locked by screws or other components, so that the support frame 120 is suspended and assembled into the first cavity 111. Similar to the second connecting post 1112, the positioning post 1114 is also integrally formed on the support wall 1111, so that the second connecting post 1112 and the positioning post 1114 have sufficient support strength, and the height of the positioning post 1114 relative to the support wall 1111 is higher than the height of the second connecting post 1112 relative to the support wall 1111.

[0106] Combination Figures 9-11 In some embodiments, multiple connecting ear plates 121 are provided, and the multiple connecting ear plates 121 are arranged circumferentially around the support frame 120. Correspondingly, the second connecting post 1112, the positioning post 1114, and the connecting ear plate 121 are arranged one-to-one. The second connecting post 1112 supports and connects to the corresponding connecting ear plate 121, and the positioning post 1114 passes through the first positioning hole 1212 on the corresponding connecting ear plate 121. By providing multiple second connecting posts 1112 and multiple positioning posts 1114, the support frame 120 can be stably assembled into the first cavity 111. For example, two connecting ear plates 121 are provided, and the two connecting ear plates 121 are arranged opposite each other on both sides of the support frame 120. Two second connecting posts 1112 and two positioning posts 1114 are also provided. This arrangement can minimize the space occupied by the connecting ear plates 121 while ensuring that the support frame 120 is stably assembled into the first cavity 111, so that the support frame 120 has enough space to assemble the main control board 131 and the main control power board 132.

[0107] In some embodiments, to ensure the stability and heat dissipation of the main control board 131 and the main control power board 132, the support frame 120 may be made of metal material (such as aluminum alloy) by stamping or made of engineering plastic by injection molding. This application does not limit this. When the support frame 120 is made of metal material, the support frame 120 can guide the heat generated by the main control board 131 and the main control power board 132 of the main control module 130 during operation to the side wall of the first housing 110.

[0108] Figure 12 An assembly diagram of the main control module 130 and the support frame 120 is shown. (Combined with...) Figure 11 as well as Figure 12In some embodiments, the support frame 120 has a first receiving groove 122 on the side facing the main control board 131, with the opening of the first receiving groove 122 facing the inspection port 112. At least a portion of the main control board 131 is disposed in the first receiving groove 122. The size and shape of at least a portion of the main control board 131 are adapted to the interior of the first receiving groove 122, so that at least a portion of the main control board 131 can be protected and isolated by the first receiving groove 122 to avoid the main control board 131 being subject to signal interference or environmental interference, thereby improving the reliability of the main control board 131 during use.

[0109] Combination Figure 11 as well as Figure 12 In some embodiments, to facilitate the installation of the main control board 131, the electrical control box 100 further includes a first latch 123. Specifically, the first latch 123 is connected to the side wall of the first receiving groove 122 or the main control board 131, and the main control board 131 is fastened to the first receiving groove 122 by the first latch 123.

[0110] In one configuration, the first clip 123 is located on the side wall of the first receiving groove 122. The first clip 123 can be made of elastic plastic. During installation, the first clip 123 is fastened to the edge of the main control board 131. The fastening force generated by its own elasticity enables the main control board 131 to be quickly connected to the support frame 120. During disassembly, the main control board 131 can be removed by simply prying the first clip 123, which is convenient for maintenance.

[0111] Figure 13 A partial assembly diagram of the first latch 123 is shown. (Combined with...) Figure 13 In some embodiments, the first receiving groove 122 has a first sidewall 1221, on which a first slot 1222 is provided. The opening side of the first slot 1222 faces the opening side of the first receiving groove 122. A first support plate 1223 is connected to the bottom of the first slot 1222. The first support plate 1223 and the two sidewalls of the first slot 1222 have gaps. A first buckle 123 is connected to the first support plate 1223. This configuration allows the first buckle 123 connected to the first sidewall 1221 with the first slot 1222 to be more easily deformed. When installing the main control board 131, the main control board 131 can be inserted obliquely into the first receiving groove 122 and abut against the first support plate 1223 with the first slot 1222, forcing the first support plate 1223 to deform outward. This makes it easier for the main control board 131 to be placed into the first buckle 123 on the other sidewall of the first receiving groove 122. When the main control board 131 is released, the first support plate 1223 returns to its original shape, and the main control board 131 is positioned in the first buckle 123, so that the main control board 131 can be quickly assembled into the first receiving groove 122 of the support frame 120.

[0112] Combination Figure 11 The first receiving slot 122 is box-shaped, and two first sidewalls 1221 are arranged opposite each other along a first direction (e.g., the width direction of the support frame 120). Four first buckles 123 are provided, distributed in pairs on the two first sidewalls 1221. One of the first sidewalls 1221 has the aforementioned first slot 1222, while the other first sidewall 1221 does not have the aforementioned first slot 1222. That is, the first buckles 123 are fixed to the inner side of the other first sidewall 1221 to limit the displacement of the main control board 131. This arrangement can facilitate the quick assembly of the main control board 131 into the first receiving slot 122 of the support frame 120, while also ensuring the reliability of the main control board 131's assembly on the support frame 120.

[0113] In another configuration, the first clip 123 is positioned on the edge of the main control board 131. For example, four first clips 123 are provided, distributed in pairs on both sides of the main control board 131. The first clips 123 can be made of elastic plastic. During installation, the first clips 123 are fastened in the openings in the sidewall of the receiving cavity. The fastening force generated by their own elasticity enables a quick connection between the main control board 131 and the support frame 120. During disassembly, the main control board 131 can be removed simply by gently prying the first clips 123, facilitating maintenance.

[0114] Combination Figure 11 as well as Figure 12 In some embodiments, the control box 100 further includes a first support block 124, which is connected to the bottom wall of the first receiving groove 122 or the main control board 131. The main control board 131 is spaced apart from the bottom of the first receiving groove 122 by the first support block 124. This arrangement allows the main control board 131 to be suspended in the first receiving groove 122, which is beneficial for heat dissipation of the main control board 131.

[0115] In one configuration, multiple first support blocks 124 are provided, and the multiple first support blocks 124 are circumferentially spaced around the edge of the bottom of the first receiving groove 122 and abut against the side wall of the first receiving groove 122. At least some of the ends of the first support blocks 124 have a first notch 1241 on their inner side (in conjunction with...). Figure 14 The main control board 131 is embedded in the first notch 1241 of the two first support blocks 124. In another configuration, multiple first support blocks 124 are positioned on the side of the main control board 131 facing the bottom of the first receiving groove 122, and the multiple first support blocks 124 abut against the bottom of the first receiving groove 122.

[0116] In some embodiments, the first support block 124 is disposed between the first buckle 123 and the bottom of the first receiving groove 122, that is, the first buckle 123 and the first support block 124 have a height difference. The first buckle and the first support block 124 can restrict the position of the main control board 131 along the opening direction of the inspection port 112, so that the main control board 131 is suspended in the first receiving groove 122.

[0117] Since the main control board 131 is suspended within the first receiving groove 122, there is a gap between the main control board 131 and the bottom of the first receiving groove 122. In order to further improve the heat dissipation effect of the main control board 131, in some embodiments, thermal adhesive is filled between the main control board 131 and the bottom of the first receiving groove 122. The thermal adhesive can be thermally conductive silicone grease. After the thermal adhesive is filled, it covers at least a part of the main control board 131, thereby quickly conducting the heat generated by the main control board 131 to the support frame 120, and then dissipating it to the external environment through the first housing 110. This reduces the operating temperature of the main control board 131, ensures that it operates within a stable temperature range, and extends the service life of the main control board 131. In addition, it also insulates the main control board 131 from the support frame 120.

[0118] Figure 15 A schematic diagram of the main control board 131 is shown. (Combined with...) Figure 15 The main control module 130 of this application is a key component for the control box 100 to realize its control functions. Specifically, the main control board 131 of the main control module 130 is the core carrier for signal processing and command output of the control box 100, and at least one interactive module 1311 is provided on it. Exemplarily, at least one interactive module 1311 includes one or more of an inspection module 13111, a storage interface module 13112, and a communication interface module 13113. Among them, the inspection module 13111 may include a display screen and buttons, allowing users to switch inspection items via buttons and view detailed parameters (such as voltage, current, and frequency) on the display screen. The storage interface module 13112 may be a USB interface, a Micro SD card interface, etc., for data transmission. The communication interface module 13113 may be an Ethernet interface, a wireless interface, a serial port interface, etc., for connecting various low-voltage lines, such as sensor signal lines and device communication lines. The main control board 131 is typically a multilayer printed circuit board (PCB), integrating key electronic components such as microprocessors, memory chips, and signal processing chips. For example, the main control board 131 includes a main control base plate 1312, and at least one interactive module 1311 is disposed on the main control base plate 1312.

[0119] Figure 16 This diagram shows the assembly of the main control cover and the support frame, combined with... Figure 16In some embodiments, the electrical control box 100 of this embodiment further includes a main control cover 160. The main control cover 160 is assembled inside the first cavity 111 and covers the opening side of the first receiving groove 122, thereby allowing the main control board 131 to be substantially within a sealed cavity, thus improving the safety protection performance of the main control board 131. The main control cover 160 can be made of insulating plastic material. The main control cover 160 covers the exposed electronic components on the main control board 131, preventing personnel from accidentally touching electronic components during routine maintenance or repair, and preventing short circuits, component damage, and other malfunctions.

[0120] Figure 17 It shows Figure 16 An explosion diagram. Figure 18 A schematic diagram of the electronically controlled cover is shown. (Combined with...) Figures 16-18 In some embodiments, a second positioning hole 1213 is provided on the connecting ear plate 121. The second positioning hole 1213 is non-circular, and a positioning member 161 is provided on the first cover 140, which is inserted into the second positioning hole 1213. The positioning member 161 and the second positioning hole 1213 can position the first cover 140. Since the second positioning hole 1213 is non-circular, it can limit the offset of the first cover 140. In specific implementations, the second positioning hole 1213 can be a square hole, and the positioning member 161 can generally be a cylindrical structure. The cross-sectional shape of the positioning member 161 is adapted to the second positioning hole 1213, and the positioning member 161 passes through the second positioning hole 1213. In other embodiments, the second positioning hole 1213 can also be elliptical, trapezoidal, etc., and this application does not impose any limitations on this.

[0121] Figure 19 It shows Figure 18 A magnified diagram of point A. Combined with... Figure 19 In some embodiments, the positioning member 161 is provided with a protrusion 162, which is located on the side of the positioning member 161 that passes through the second positioning hole 1213, that is, the protrusion 162 is located on the side of the connecting ear plate 121 facing away from the main control cover 160, so as to limit the displacement of the main control cover 160 by means of the protrusion 162. Exemplarily, the positioning member 161 is formed by a sheet metal part and has a certain elasticity. The positioning member 161 can deform when passing through the second positioning hole 1213. After the positioning member 161 passes through the second positioning hole 1213, the positioning member 161 returns to its deformed state, and the protrusion 162 is engaged on the connecting ear plate 121. In another embodiment, the positioning member 161 is not elastic, and the protrusion 162 is a thin plate structure. When the positioning member 161 passes through the second positioning hole 1213, the protrusion 162 can deform to pass smoothly through the second positioning hole 1213. After the protrusion 162 passes through the second positioning hole 1213, the protrusion 162 returns to its original shape and is locked on the connecting ear plate 121. Both of these can limit the displacement of the main control cover 160 by the protrusion 162.

[0122] Since there are multiple connecting ear plates 121, the positioning member 161 and the connecting ear plate 121 are respectively provided one-to-one. The positioning member 161 is inserted into the second positioning hole 1213 on the corresponding connecting ear plate 121, so as to limit the displacement of the first cover 140 through multiple positioning members, so that it can stably seal the opening of the first receiving groove 122.

[0123] Figure 20 It shows Figure 18 A frontal view diagram. Combined with... Figure 20 In some embodiments, the main control cover 160 is provided with at least one window 163 for displaying the interaction module 1311 of the main control board 131. Exemplarily, the interaction module 1311 includes a communication interface module 13113, and the window 163 includes a first window 1631 for displaying the communication interface module 13113. Thus, while ensuring effective protection of other electronic components of the main control board 131, maintenance personnel do not need to disassemble the entire main control cover 160 when wiring communication lines; they only need to operate on the first window 1631 to complete the wiring of low-voltage lines, making the operation convenient and safe. The first window 1631 is located at the bottom edge of the main control cover 160, so that cables can be directly led out from the bottom edge of the main control cover 160 during wiring, facilitating wiring operations.

[0124] Combination Figure 20 In some embodiments, the interaction module 1311 further includes an inspection module 13111, and the main control cover 160 is correspondingly provided with a second window 1632. The second window 1632 is used to display the inspection module 13111, so that maintenance personnel can view the working status parameters of the electrical control box 100 in real time.

[0125] Combination Figure 20 In some embodiments, the interaction module 1311 further includes a storage interface module 13112, and the main control cover 160 is correspondingly provided with a third window 1633, which is used to expose the storage interface module 13112. The storage interface module 13112 is used to realize data interaction between the electronic control box 100 and external storage devices. Taking the storage interface module 13112 including a USB interface as an example, the USB interface can not only transmit data, but also connect devices such as USB flash drives to realize bidirectional data transmission. In this embodiment, the third window 1633 is provided to facilitate users to connect external storage devices and facilitate operation. In some embodiments, as shown in the figure, the main control cover 160 is provided with a clearance structure to avoid electronic components on the main control board 131. Specifically, the side of the main control cover 160 facing the main control board 131 is provided with a clearance cavity 1634, the shape of which is adapted to the layout of electronic components on the main control board 131, so as to reserve sufficient space for electronic components and avoid squeezing and damaging the components when the main control cover 160 is installed.

[0126] Combination Figure 20 In some embodiments, the third window 1633 is formed on the side wall of the clearance cavity 1634, while a first clearance groove 1635 is provided on the side of the main control cover 160 facing away from the main control board 131. The third window 1633 connects the clearance groove 1635 and the clearance cavity 1634. From a top view, the storage interface module 13112 is covered by the main control cover 160, making it less likely to be accidentally touched. When it is necessary to connect an external storage device, maintenance personnel can insert the external storage device through the first clearance groove 1635 and the third window 1633 to connect to the storage interface module 13112. This operation is convenient and does not affect the protective function of the main control cover 160.

[0127] Combination Figure 8 as well as Figure 16 In some embodiments, a limiting member 164 is provided on the side of the main control cover 160 facing the first cover 140. The limiting member 164 and the corresponding support member 143 on the inner side of the first cover 140 are provided one-to-one. The limiting member 164 and the corresponding support member 143 cooperate with each other to form a hovering assembly, thereby limiting the first cover 140. This hovering assembly allows the first cover 140 to hover at a preset angle during the opening process, preventing the first cover 140 from accidentally closing during operation, thereby providing a stable and convenient operating environment for maintenance personnel.

[0128] Specifically, combined Figure 16 The connection method of the limiting component 164 can be welding, bonding, or integral molding, depending on the material properties of the limiting component 164 and the main control cover 160. For example, if both are made of plastic, an integral injection molding connection method can be used.

[0129] During the opening of the first cover 140, the support member 143 moves with the rotation of the first cover 140 and eventually abuts against the limiting member 164, thereby suspending the first cover 140. For example, the limiting member 164 is made of an elastic material, such as elastic plastic, rubber, silicone, etc., so that the limiting member 164 has a certain degree of elasticity.

[0130] Combination Figure 16 In some embodiments, the main control cover 160 is provided with a second clearance groove 165 into which the support member 143 can be inserted. The shape and size of the second clearance groove 165 are adapted to the support member 143, providing sufficient space for the support member 143 to move. The second clearance groove 165 is located at the edge of the main control cover 160 to avoid interfering with the module located in the center of the electrical control box.

[0131] Combination Figure 16A limiting member 164 is disposed on one side of the second clearance groove 165. Exemplarily, one end of the limiting member 164 is connected to the opening of the second clearance groove 165, and the other end is provided with a blocking block 1641. The blocking block 1641 is used to abut against the support member 143, so that the first cover 140 is suspended. The blocking block 1641 is block-shaped and can abut against the end of the support member 143. When the first cover 140 is opened, the support member 143 will squeeze the limiting member 164. Because the limiting member 164 has a certain elasticity, its free end will swing at a small angle under the action of external force to avoid the movement trajectory of the support member 143. This small-angle swing is achieved based on the elastic deformation capability of the limiting member 164, which can provide space for the movement of the support member 143 without damaging its own structure.

[0132] During the opening of the first cover 140, the support member 143 moves along with the movement of the first cover 140. When the first cover 140 is opened to a preset angle, the support member 143 no longer presses against the limiting member 164. At this time, the limiting member 164 returns to its original position under its own elastic force, so that the blocking block can abut against the end of the support member 143, thereby blocking the tendency of the first cover 140 to close, and allowing the first cover 140 to be stably suspended at the preset angle.

[0133] The preset angle can be designed according to actual operational needs. When performing inspections, wiring operations, or connecting the storage interface module 13112, maintenance personnel require a suitable operating space and viewing angle. Fixing the first cover 140 at the preset angle using the hovering component ensures that the first cover 140 will not interfere with operations, improving convenience and efficiency. Simultaneously, the hovering component reduces the risk of damage caused by accidental closure of the first cover 140, enhancing operational safety. Furthermore, maintenance personnel do not need to manually support the first cover 140 during various operations, allowing for more free operation with both hands, improving the accuracy and efficiency of inspection and maintenance.

[0134] Figure 21 It shows Figure 11 Another structural diagram from the perspective of Figure 22 It shows Figure 12 A structural diagram from another perspective. Combined with... Figure 21 as well as Figure 22In some embodiments, the support frame 120 has a second receiving groove 125 on the side facing the main control power board 132, with the opening side of the second receiving groove 125 facing away from the inspection port 112. At least a portion of the main control power board 132 is disposed in the second receiving groove 125. The size and shape of at least a portion of the main control power board 132 are adapted to the interior of the second receiving groove 125 so that at least a portion of the main control power board 132 can be protected and isolated by the second receiving groove 125 to avoid signal interference or environmental interference to the main control power board 132, thereby improving the reliability of the main control power board 132 during use.

[0135] Combination Figure 21 as well as Figure 22 In some embodiments, to facilitate the installation of the main control power board 132, the control box 100 further includes a second latch 126. Specifically, the second latch 126 is connected to the side wall of the second receiving groove 125 or the main control power board 132, and the main control power board 132 is fastened into the second receiving groove 125 by the second latch 126.

[0136] In one configuration, the second clip 126 is located on the side wall of the second receiving groove 125. The second clip 126 can be made of elastic plastic. During installation, the second clip 126 is fastened to the edge of the main control power board 132. The fastening force generated by its own elasticity enables the main control power board 132 to be quickly connected to the support frame 120. During disassembly, the main control power board 132 can be removed by simply prying the second clip 126, which is convenient for maintenance.

[0137] Figure 23 A partial assembly diagram of the second latch 126 is shown. (Combined with...) Figure 23 In some embodiments, the second receiving groove 125 has a second sidewall 1251, and a second slot 1252 is provided on the second sidewall 1251. The opening side of the second slot 1252 faces the opening side of the second receiving groove 125. A second support plate 1253 is connected to the bottom of the second slot 1252. Both the second support plate 1253 and the two sidewalls of the second slot 1252 have gaps. A second buckle 126 is connected to the second support plate 1253. This configuration allows the second latch 123 connected to the second sidewall 1251 with the second slot 1252 to be more easily deformed. When installing the main control power board 132, the main control power board 132 can be inserted obliquely into the second receiving groove 125 and abut against the second support plate 1253 with the second slot 1252, forcing the second support plate 1253 to deform outward. This makes it easier for the main control power board 132 to be placed into the second latch 126 on the other sidewall of the second receiving groove 125. After releasing the main control power board 132, the second support plate 1253 returns to its original shape, and the main control power board 132 is positioned in the second latch 126, so that the main control power board 132 can be quickly assembled into the second receiving groove 125 of the support frame 120.

[0138] Combination Figure 21 The second receiving slot 125 is box-shaped, and two second side walls 1251 are arranged opposite each other along a first direction (e.g., the width direction of the support frame 120). Four second buckles 126 are provided, distributed in pairs on the two second side walls 1251. One of the second side walls 1251 has the aforementioned second slot 1252, while the other second side wall 1251 does not have the aforementioned first slot 1252. That is, the second buckles 126 are fixed to the inner side of the other second side wall 1252 to limit the displacement of the main control power board 132. This arrangement can facilitate the quick assembly of the main control power board 132 into the second receiving slot 125 of the support frame 120, while also ensuring the reliability of the main control power board 132's assembly on the support frame 120.

[0139] Combination Figure 11 as well as Figure 21 In some embodiments, the first sidewall 1221 and the second sidewall 1251 are arranged in a one-to-one correspondence. The first sidewall 1221 and the corresponding second sidewall 1251 are arranged opposite to each other along the direction from the main control board 131 to the main control power board 132. The first sidewall 1221 with the first slot 1222 and the second sidewall 1251 with the second slot 1252 are arranged opposite to each other along a first direction, which intersects the arrangement direction from the main control board 131 to the main control power board 132. That is, the first sidewall 1221 with the first slot 1222 and the second sidewall 1251 with the second slot 1252 are located on different sides of the support frame 120. This arrangement can ensure that the support frame 120 has sufficient support strength while ensuring convenient assembly of the main control board 131 and the main control power board 132, thereby improving the reliability of the assembly of the main control board 131 and the main control power board 132 within the support frame 120.

[0140] In another configuration, the second clips 126 are positioned on the edge of the main control power board 132. For example, four second clips 126 are provided, distributed in pairs on both sides of the main control power board 132. The second clips 126 can be made of elastic plastic. During installation, the second clips 126 engage with openings in the sidewalls of the receiving cavity, utilizing their own elasticity to achieve a quick connection between the main control power board 132 and the support frame 120. During disassembly, the main control power board 132 can be removed simply by gently prying open the second clips 126, facilitating maintenance.

[0141] Combination Figure 21 as well as Figure 22In some embodiments, the control box 100 further includes a second support block 127, which is connected to the bottom of the second receiving slot 125 or the main control power board 132. The main control power board 132 is spaced apart by the second support block 127 and the bottom of the second receiving slot 125. This arrangement allows the main control power board 132 to be suspended within the second receiving slot 125, which facilitates heat dissipation of the main control power board 132.

[0142] Combination Figure 21 as well as Figure 22 In one configuration, multiple second support blocks 127 are provided, circumferentially spaced around the edge of the bottom of the second receiving groove 125 and abutting against the sidewall of the second receiving groove 125. At least some of the ends of the second support blocks 127 have second notches 121 on their inner sides, and the main control power board 132 is embedded in the second notches 121 of two of the second support blocks 127. In another configuration, multiple second support blocks 127 are provided on the side of the main control power board 132 facing the bottom of the second receiving groove 125, and the multiple second support blocks 127 abut against the bottom of the second receiving groove 125.

[0143] In some embodiments, the second support block 127 is disposed between the bottom of the second latch 126 and the second receiving groove 125, that is, the second latch 126 and the second support block 127 have a height difference. The second latch and the second support block 127 can restrict the position of the main control power board 132 along the opening direction of the inspection port 112, so that the main control power board 132 is suspended in the second receiving groove 125.

[0144] Since the main control power board 132 is suspended within the second receiving slot 125, and there is a gap between the bottom of the main control power board 132 and the bottom of the second receiving slot 125, in order to further improve the heat dissipation effect of the main control power board 132, in some embodiments, thermal adhesive is filled between the main control power board 132 and the bottom of the second receiving slot 125. The thermal adhesive can be thermally conductive silicone grease. After the thermal adhesive is filled, it covers at least a part of the main control power board 132, thereby quickly conducting the heat generated by the main control power board 132 to the support frame 120, and then dissipating it to the external environment through the second housing 180. This reduces the operating temperature of the main control power board 132, ensures that it operates within a stable temperature range, extends the service life of the main control power board 132, and also insulates the main control power board 132 from the support frame 120.

[0145] In some embodiments, the electronic components on the main control board 131 are located on the side of the main control board 131 facing away from the main control power board 132, that is, the electronic components on the main control board 131 are located on the side of the main control board 131 facing the access port 112, and the electronic components on the main control power board 132 are located on the side of the main control power board 132 facing away from the main control board 131, that is, the electronic components on the main control power board 132 are located on the side of the main control board 131 facing away from the access port 112. When a fault occurs inside the electrical control box 100 and needs to be repaired, maintenance personnel can directly access the electronic components on the main control board 131 without flipping it over, and quickly troubleshoot and repair the fault, thereby improving maintenance efficiency. In addition, it also allows the side of the main control board 131 and the main control power board 132 facing the support frame 120 to be free of electronic components, so as to avoid the thermal paste affecting the operation of the electronic components.

[0146] Combination Figure 22 In some embodiments, the main control power board 132 is provided with a rectifier and filter circuit 1321, which is used to convert high-voltage electricity into low-voltage electricity. Exemplarily, the rectifier and filter circuit 1321 includes a transformer 13211 and a capacitor transformer 13212. The transformer 13211 is used to reduce the voltage of the input high-voltage electricity. The capacitor transformer 13212 is used to filter the low-voltage electricity output from the transformer 13211, smoothing the voltage waveform and making the output low-voltage electricity more stable.

[0147] Since the main control power board 132 is located on the side of the support frame 120 facing away from the inspection port 112, that is, the support frame 120 covers the rectifier and filter circuit 1321, forming a physical shield for the rectifier and filter circuit 1321, it avoids direct exposure of components such as the transformer 13211 and capacitor transformer 13212 in the rectifier and filter circuit 1321. The support frame 120 hides the rectifier and filter circuit 1321, which on the one hand prevents users from accidentally touching the live components in the rectifier and filter circuit 1321 when operating the control box 100 or performing maintenance, thus avoiding electric shock and improving the safety of using the control box 100; on the other hand, it also reduces the corrosion of the rectifier and filter circuit components by external dust, moisture, etc., protecting the circuit components and extending the service life of the control box 100.

[0148] In some embodiments, at least a portion of the first housing 110 may be supported by a material with good thermal conductivity, such as aluminum alloy. Alternatively, the interior of the first housing 110 may have a heat sink, which may be straight or curved, for guiding the flow of the heat exchange medium, such as air or liquid, i.e., removing heat by air cooling or water cooling.

[0149] Combined again Figure 3 as well as Figure 4In some embodiments, the electrical control box 100 includes a cold plate body 170 and a first enclosure plate 171. The cold plate body 170 can be made of a material with good thermal conductivity, such as aluminum alloy or copper alloy, and has a plate-like structure. The first enclosure plate 171, the cold plate body 170, and the first cover 140 cooperate to form a first cavity 111.

[0150] In this embodiment, the heat dissipation capacity of the entire electrical control box 100 is improved by the cooperation of the heat dissipation adhesive filled between the cold plate body 170 and the support frame 120, the main control board 131 and the main control power board 132.

[0151] Specifically, the support frame 120 acts as a bridge throughout the heat dissipation process. Because the thermal adhesive conducts heat to the support frame 120, it becomes an intermediate heat carrier. On one hand, the thermal adhesive filling the space between the support frame 120 and the main control board 131 and main power board 132 dissipates heat; on the other hand, the support frame 120, guided by the second connecting post 1112 and the positioning post 1114, can transfer heat from the support frame 120 to the cold plate body 170, ensuring effective heat dissipation and enabling the control board and main power board 132 to function normally.

[0152] The cold plate body 170 is the core component of the entire heat dissipation system. When heat is transferred to the cold plate body 170, it dissipates the heat to the external environment through heat exchange. Through the combined action of the cold plate body 170 and the thermal adhesive of the support frame 120, a highly efficient heat dissipation system is formed. The heat generated by the main control board 131 and the main power board 132 can be quickly transferred to the external environment, reducing the operating temperature of the main control board 131 and the main power board 132, ensuring the stable operation of the electrical control box 100, extending its service life, and improving the reliability and performance of the entire system.

[0153] In one configuration, the first enclosure plate 171 and the cold plate body 170 are made of the same thermally conductive material (such as aluminum alloy, copper alloy, etc.) and formed into an integral structure through an integrated molding process. For example, by using a casting process, the cold plate body 170 and the first enclosure plate 171 can be made into an integral structure, which can ensure that there is no seam between the two and improve the thermal conductivity.

[0154] The first cover 160, the first surrounding plate 171, and the cold plate body 170 cooperate to form a first cavity 111, in which the main control module 130 is installed. Since the main control module 130 generates relatively little heat, in this embodiment, no heat sink is provided on the portion of the cold plate body 170 corresponding to the main control module 130; instead, heat dissipation is achieved through the enclosed structure formed by the first surrounding plate 171 and the cold plate body 170. This enclosed heat dissipation method allows heat to be evenly conducted from the main control module 130 to the surfaces of the cold plate body 170 and the first surrounding plate 171, and then dissipated through heat exchange with the outside air, thus meeting the heat dissipation requirements of the main control module 130. Simultaneously, it avoids the problem of excessively low temperatures in the cold plate body 170 that might result from a heat sink, preventing condensation of moisture in the air on the surface of the main control module 130 due to excessively low temperatures, which could lead to short circuits and other malfunctions. The above-mentioned heat dissipation structure design ensures effective heat dissipation while improving the reliability and stability of the electrical control box 100.

[0155] Figure 24 It shows Figure 3 A schematic diagram of the explosion. Combined with... Figure 24 In some embodiments, the control box 100 further includes a second box 180, and a second cavity 181 is formed inside the second box 180, thereby enabling the control box 100 to construct a multi-cavity structure, breaking the limitations of the traditional single cavity and providing a spatial basis for the functional expansion of the control box 100.

[0156] Specifically, the cold plate body 170, as a key connecting component, extends from the first box 110. The electrical control box 100 also includes a second enclosure 172 and a second cover 173. The second enclosure 172 is connected to one side of the cold plate body 170, and the first enclosure 171 and the second enclosure 172 are connected to the same side of the cold plate body 170. The second cover 173 and the second enclosure 172 are sealed together with the cold plate body 170 to form a second box 180 with a second cavity 181. The electrical control box 100 also includes a frequency converter module (not shown). The frequency converter module includes a drive board and a filter board. The drive board is mainly used for frequency conversion drive control of loads such as motors and fans. By adjusting the output voltage and frequency, it realizes the speed regulation, start and stop functions of motors and fans. The filter board filters the input and output currents, removes harmonic interference, and improves power quality. At least one of the drive board and the filter board is disposed in the second cavity 181. As core components of the frequency converter module, the drive board and filter board generate heat during operation. If heat cannot be dissipated effectively and promptly, their performance and lifespan will be severely affected. In this embodiment, a heat sink 900 is installed inside the second cavity 181 to effectively dissipate heat and ensure the normal operation of the frequency converter module.

[0157] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
