DETAILED DESCRIPTION

[0065] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0066] The control cabinet according to an embodiment of the present application is described below with reference to Figures 1 to 22.

[0067] An embodiment of the present application provides a control cabinet, as shown in Figures 1 to 5 , which includes a backplane 110, a housing 120 and electronic devices 200.

[0068] As shown in FIG1 to FIG5 , the control cabinet may be an elevator control cabinet for controlling the operation of an elevator, or may be a control cabinet for use in other fields.

[0069] The housing 120 of the control cabinet can be made of carbon steel, cold-rolled plate, stainless steel, alloy steel or other suitable materials.

[0070] As shown in Figures 1 to 5, the casing 120 defines a accommodating cavity with an open back, and the casing 120 is detachably connected to the back panel 110. The casing 120 can be a rectangular structure, a trapezoidal structure or other shape structure with an open back. The casing 120 and the back panel 110 can be detachably connected by bolts, snaps or other means.

[0071] As shown in FIG. 1 to FIG. 5 , when the housing 120 is connected to the back plate 110 , the accommodating cavity defined by the housing 120 may be a rectangular structure, or an elliptical, trapezoidal, or other shaped structures.

[0072] As shown in Figures 1 to 5, the electronic device 200 is installed on the back panel 110 and is located in the accommodating cavity. The electronic device 200 can be installed on the side of the back panel 110 close to the housing 120 by bolts, screws or other means. When the back panel 110 is connected to the housing 120, the electronic device 200 is located in the accommodating cavity of the housing 120.

[0073] During the actual implementation process, when the staff installs the electronic devices 200, they install each electronic device 200 on the back panel 110 with bolts. After all the electronic devices 200 are installed, the housing 120 is covered on the outside of all the electronic devices 200 and connected to the back panel 110. After the entire control cabinet is assembled, it is fixed vertically in the designated position; when the staff needs to repair the electronic devices 200 inside the control cabinet, the housing 120 can be disassembled from the back panel 110 and moved away from the back panel 110 to be removed. At this time, the electronic devices 200 are exposed to the external environment and can be repaired or replaced by the staff.

[0074] By setting the housing 120 and the back panel 110 to be detachably connected, there is no need to reserve operating space near the inner wall of the housing 120. When installing the electronic device 200, the electronic device 200 can be arranged as close to the edge of the back panel 110 as possible to achieve a smaller assembly process gap. Compared with directly assembling the electronic device 200 inside the control cabinet, it can save space for the staff to start installation, improve the space utilization inside the control cabinet, and reduce the overall volume of the control cabinet. At the same time, the electronic device 200 can be maintained or replaced in an open environment, and the electronic device 200 can be installed or removed without constraints, thereby improving the assembly efficiency and maintenance efficiency of the electronic device 200.

[0075] According to the control cabinet provided in the embodiment of the present application, by setting the housing 120 and the back panel 110 to be detachably connected, the overall volume of the control cabinet can be reduced, while facilitating the installation and maintenance of the electronic device 200, and improving the installation efficiency and maintenance efficiency.

[0076] In some embodiments, as shown in FIG. 1-FIG . 4 and FIG. 6 - FIG. 8 , the housing 120 includes a housing body 121 and a door 122 .

[0077] 1-4 and 6-8, the front and back of the casing body 121 are open, and the casing body 121 is detachably connected to the back panel 110. The casing body 121 can be a rectangular structure with an open front and back, or a circular, trapezoidal or other shape structure.

[0078] As shown in Figures 1 to 4 and Figures 6 to 8, the door body 122 is connected to the casing body 121 and is used to at least partially shield the front of the casing body 121. The door body 122 can be pivotally connected to the casing body 121. For example, the door body 122 is rotatably connected to one side of the front side of the casing body 121 by a hinge 1221 or other means, that is, the door body 122 can be rotated relative to one side of the front side of the casing body 121 by the hinge 1221; the door body 122 can also be slidably connected to the casing body 121. For example, a slide rail is provided on the front side of the casing body 121, and a slider is provided on the side of the door body 122. The door body 122 and the casing body 121 are slidably connected through the slide rail and the slider.

[0079] As shown in Figures 1, 3, 6-8, a door lock 1222 is provided on the front side of the door body 122. The door lock 1222 can be locked when the control cabinet is working normally. The door lock 1222 can be unlocked when it is necessary to observe or operate the electronic device 200 inside the control cabinet to improve the safety of the electronic device 200.

[0080] As shown in Figures 1, 3, 6-8, the door lock 1222 can be set on the front side of the door body 122 and opposite to the rotating axis of the door body 122, and the door lock 1222 can protrude outward relative to the front surface of the door body 122, that is, the door lock 1222 can serve as the door handle of the door body 122. The structure is simple and it is convenient for the staff to open the door body 122.

[0081] During actual implementation, when the control cabinet is in normal working condition or has no faults, the door body 122 is locked with the casing body 121 through the door lock 1222. At this time, the door body 122 cannot be opened, and the door body 122 blocks the front of the casing body 121; when it is necessary to observe the inside of the control cabinet, open the door lock 1222 and pull the door lock 1222 to rotate the door body 122 relative to the rotation axis in the direction away from the casing body 121 until the door body 122 completely does not block the front of the casing body 121.

[0082] By providing the door body 122 , the electronic device 200 can be prevented from being exposed to the external environment and affected by dust or other substances, thereby improving the safety of the electronic device 200 and improving the overall neatness of the exterior of the control cabinet.

[0083] In some embodiments, as shown in Figures 1-4 and Figures 6-8, the casing body 121 includes a first side panel 1211, a top panel 1212, a second side panel 1213 and a cover panel 1214 connected in sequence end to end, wherein the cover panel 1214 is detachably connected to one end of the first side panel 1211 and the second side panel 1213 facing away from the top panel 1212, and the first side panel 1211 and the second side panel 1213 are detachably connected to the back panel 110.

[0084] 1 to 4 and 6 to 8 , the first side panel 1211 , the top panel 1212 and the second side panel 1213 may be integrally formed, or they may be formed separately and then fixedly connected by screws, bolts or other means.

[0085] As shown in Figures 1 to 4 and Figures 6 to 8, the first side panel 1211, the top panel 1212, the second side panel 1213 and the cover panel 1214 can all be rectangular structures, or can be trapezoidal or other shape structures. The first side panel 1211 can form a right-angle structure with the top panel 1212 and the cover panel 1214 respectively, and the second side panel 1213 can form a right-angle structure with the top panel 1212 and the cover panel 1214 respectively. That is, the first side panel 1211, the top panel 1212, the second side panel 1213 and the cover panel 1214 can be connected end to end in sequence to form a rectangular structure, or can form a trapezoidal or other shape structures, and there is no limitation here.

[0086] As shown in Figures 1-4 and Figures 6-8, the side of the first side panel 1211 close to the back panel 110 in the width direction and the side of the second side panel 1213 close to the back panel 110 in the width direction are both detachably connected to the back panel 110, and the side of the first side panel 1211 close to the cover panel 1214 in the length direction and the side of the second side panel 1213 close to the cover panel 1214 in the length direction are both detachably connected to the cover panel 1214.

[0087] As shown in Figures 1, 2, 4, 6-8, the top plate 1212 is provided with a first fan 1216 and a second fan 1217 at positions close to the second side plate 1213 and the first side plate 1211, respectively. The cover plate 1214 is provided with a plurality of heat dissipation holes 1215 at positions corresponding to the first fan 1216 and the second fan 1217. The heat dissipation holes 1215 can be arranged in the form of multiple rows of crosses, or in other ways. The first fan 1216 can be set to two, the second fan 1217 can be set to two, or the first fan 1216 and the second fan 1217 can be set to other numbers.

[0088] By setting up the first fan 1216, the second fan 1217 and the heat dissipation holes 1215, the first fan 1216 and the second fan 1217 can be used to cool the electronic components 200 inside the control cabinet, and the heat dissipation holes 1215 can exchange the high-temperature air inside the control cabinet with the low-temperature air in the external environment, thereby improving the heat dissipation effect; because the heat dissipation holes 1215 on the cover 1214 are prone to dust accumulation during long-term use, and when there is a lot of dust, the heat dissipation holes 1215 are easily blocked, which can easily lead to poor heat dissipation inside the control cabinet and damage to the electronic components 200, so the cover 1214 is set to be detachably connected to the first side panel 1211 and the second side panel 1213, and the cover 1214 can be removed from the casing body 121 separately, so that the staff can clean the cover 1214 regularly to ensure the heat dissipation effect of the control cabinet. At the same time, there is no need to disassemble other parts of the casing 120, and the operation is simple.

[0089] In some embodiments, as shown in FIG. 1 to FIG. 8 , the control cabinet further includes a handle 130 . The handle 130 is connected to the housing 120 , and the housing 120 is provided with a reinforcement 131 in the area connected to the handle 130 .

[0090] 1 to 8 , a handle 130 is installed on the first side panel 1211 and the second side panel 1213 near the top panel 1212. The handle 130 can be formed by bending a strip structure twice, or it can be other shapes.

[0091] As shown in Figure 3, the reinforcement 131 can be a rectangular structure, or an elliptical or other shape structure. The two reinforcements 131 are respectively located at the position corresponding to the handle 130 on the inner side of the first side panel 1211 and the position corresponding to the handle 130 on the inner side of the second side panel 1213. The two handles 130 are respectively connected to the two reinforcements 131 by bolts, screws or other means.

[0092] By providing handles 130 on the outside of both the first side panel 1211 and the second side panel 1213, workers can lift the control cabinet with both hands, saving physical effort. By providing a reinforcement member 131 on the inside of the housing 120 at a position corresponding to the handle 130, the thickness of the housing 120 at the connection between the handle 130 and the housing 120 can be increased, thereby improving the strength of the portion of the housing 120 corresponding to the handle 130, preventing deformation of the housing 120 at the connection between the handle 130 and the housing 120 under external forces. At the same time, the thickness of other parts of the housing 120 does not need to be increased, saving material and production costs. The reinforcement member 131 can be made of sheet metal.

[0093] In some embodiments, as shown in FIG. 1-FIG . 8 , the back plate 110 includes a main plate body 111 and a flange 113 .

[0094] As shown in Figure 4, a connecting structure 112 is provided on the back of the main board body 111, and the electronic device 200 is installed on the front of the main board body 111 and connected to the connecting structure 112. The back of the main board body 111 is the end face of the main board body 111 facing away from the casing 120, and the front of the main board body 111 is the end face of the main board body 111 close to the casing 120. The connecting structure 112 can be a nut of the back plate 110 provided on the back of the main board body 111.

[0095] As shown in FIG4 , a plurality of nuts can be provided on the back plate 110 , and the plurality of nuts are arranged at intervals on the back plate 110 , and the plurality of nuts are respectively located at positions on the back side of the back plate 110 corresponding to the installation positions of the electronic devices 200 .

[0096] As shown in Figures 1 to 8, the flange 113 is connected to the edge of the main board body 111, and the main board body 111 and the first side panel 1211 and the second side panel 1213 are connected with flanges 113 on both sides. The flange 113 is folded relative to the main board body 111 in the direction away from the casing 120. The cross-section of the flange 113 can be an L-shaped structure, or a stepped structure or other shape structure. The first section of the flange 113 is connected to and perpendicular to the main board body 111, and the height of the first section of the flange 113 is greater than the height of the connecting structure 112. The second section of the flange 113 is parallel to the main board body 111 and protrudes outward relative to the two sides of the main board body 111 and the first side panel 1211 and the second side panel 1213.

[0097] As shown in Figures 1 to 8, the casing 120 is detachably connected to the flange 113, and an outer shell fixing frame 140 is provided on the outer side of the first side panel 1211 and the second side panel 1213 near the back. The outer shell fixing frame 140 is also an L-shaped structure. One end of the outer shell fixing frame 140 is connected to the corresponding first side panel 1211 or the second side panel 1213. When the casing 120 is connected to the back panel 110, the other end of the outer shell fixing frame 140 is overlapped with the second section of the flange 113 of the back panel 110 and the two are connected by bolts, screws or other means.

[0098] As shown in Figures 1 to 8, the flange 113 is provided with an assembly structure 1131 for installing the control cabinet. The assembly structure 1131 can be two waist-shaped holes provided on the second section of the flange 113, or it can be an assembly structure 1131 of other numbers and other forms. The two waist-shaped holes are spaced apart along the length direction of the flange 113, and the outer shell fixing frame 140 and the position corresponding to the assembly structure 1131 on the flange 113 are also provided with waist-shaped holes.

[0099] As shown in Figures 1 to 8, both ends of the flange 113 in the length direction are provided with rounded corners to prevent the edges of the flange 113 from being too sharp and causing workers to be scratched by the edges of the flange 113 when carrying, installing or removing the back panel 110.

[0102] In some embodiments, as shown in Figures 1, 2 and 5, the control cabinet also includes a grounding member 500, at least part of which is arranged on the outside of the backplane 110 for electrically connecting to the on-site grounding point, and the grounding wire of the electronic device 200 is connected to the grounding member 500.

[0103] As shown in FIG1 , FIG2 and FIG5 , the grounding member 500 may be a grounding bar, and the grounding member 500 is made of copper material, that is, the grounding member 500 may be a grounding copper bar.

[0104] During the actual implementation process, the grounding wires of the electronic devices 200 and boards inside the control cabinet are electrically connected to the grounding copper busbar, and the ground wires of the power lines entering and exiting the control cabinet are also electrically connected to the grounding copper busbar. At the same time, the grounding copper busbar is electrically connected to the on-site grounding point through cables.

[0105] In related technologies, the grounding of the electronic devices 200 and boards inside the control cabinet is usually achieved through the outer casing of the control cabinet, but the outer casing is made of iron plate with large impedance. Therefore, the grounding of the boards and electronic devices 200 is often unreliable, affecting performance. At the same time, some outer casings require plastic spraying, and the plastic powder insulation makes it impossible to ground through the outer casing.

[0106] According to the control cabinet provided in the embodiment of the present application, by providing a grounding piece 500, the grounding wires of the electronic components 200 inside the control cabinet, the grounding wires of the boards, and the ground wires of the power lines of the external input and output lines of the control cabinet can be connected to the on-site grounding point through the grounding piece 500. Since the grounding piece 500 is a grounding copper busbar, it has strong conductivity and low impedance, thereby improving the reliability of the grounding of each component.

[0107] In some embodiments, as shown in Figure 5, the grounding member 500 includes a first grounding member 510 and a second grounding member 520. The first grounding member 510 is arranged on the inner side of the back panel 110, and the grounding wire of the electronic device 200 is connected to the first grounding member 510; the second grounding member 520 is arranged on the outer side of the back panel 110 and is connected to the first grounding member 510. The second grounding member 520 is used to electrically connect the on-site grounding point.

[0108] As shown in Figure 5, the first grounding member 510 is installed at the upper end of the inner side of the backplane 110, and the first grounding member 510 is located on the inner side of the casing 120, and the grounding wires of each electronic device 200 and board in the control cabinet are electrically connected to the first grounding member 510.

[0109] As shown in Figure 5, the second grounding member 520 is installed at the upper end of the outer side of the backplane 110. The second grounding member 520 is electrically connected to the first grounding member 510. At the same time, the second grounding member 520 is connected to the first grounding member 510 by bolts, screws or other means. The ground wire of the power line of the external input and output line of the control cabinet is electrically connected to the second grounding member 520, and the second grounding member 520 is electrically connected to the on-site grounding point through a cable.

[0110] By providing a first connector 360 and a second connector 360 that are rigidly connected together, the grounding reliability of the electronic device 200, the board and the external input and output lines can be improved. At the same time, the internal and external grounding of the control cabinet are unified, which can simplify the grounding operation and facilitate the staff to perform the grounding operation.

[0111] In some embodiments, the back plate 110 is provided with a notch, and the first grounding member 510 and the second grounding member 520 are in contact at the notch.

[0112] Among them, a notch is provided at the upper end of the main body 111 of the back panel 110, the first grounding member 510 is located in the notch, the second grounding member 520 is located on the outside of the back panel 110, and the second grounding member 520 is connected by bolts, screws or other means, and the first grounding member 510 is in contact with the second grounding member 520 in the notch.

[0113] By arranging the first grounding member 510 and the second grounding member 520 to contact each other at the notch of the back plate 110 , the connection reliability between the first grounding member 510 and the second grounding member 520 can be improved, and the grounding reliability of each component can be further improved.

[0114] The following describes in detail the arrangement and structure of the display device 300 in the control cabinet of the embodiment of the present application.

[0115] In some embodiments, as shown in FIG. 1 , FIG. 3 , and FIG. 6 to FIG. 10 , the control cabinet further includes a display device 300 , the housing 120 is provided with an opening 123 , and an indication area 310 of the display device 300 is exposed in the opening 123 .

[0116] 1 , 3 , 6 to 10 , the portion of the display device 300 other than the internal UCMP board 391 (Unintended car movement protection system) is the human-machine interaction portion of the control cabinet. The display device 300 is installed inside the control cabinet. The door body 122 of the housing 120 is provided with an opening 123 at a position corresponding to the display device 300. The size and shape of the opening 123 are the same as those of the display device 300. For example, if the display device 300 is a rectangular structure as a whole, the opening 123 is also a rectangular structure. When the door body 122 is closed, the front end face of the display device 300 passes through the opening 123 of the door body 122 and protrudes outward relative to the front surface of the door body 122.

[0117] As shown in Figure 9, the indication area 310 of the display device 300 is an area used to indicate the working status of each electronic device 200. The indication area 310 can display the working status of each electronic device 200 through light. For example, when the light is green, the electronic device 200 corresponding to the light is in normal working condition. If the light is red, it means that the electronic device 200 corresponding to the light has stopped working or has malfunctioned, or the working status of the electronic device 200 can be displayed in other forms.

[0118] As shown in Figures 9 and 10, the display device 300 may include a button panel 380, a display panel 390, a conversion switch 343, a transparent panel 342, an emergency stop button 344 and a key 345. The conversion switch 343 and the emergency stop button 344 can be arranged side by side or in other ways. There are multiple keys 345, and the multiple keys 345 correspond to different functions, and the multiple keys 345 are arranged in the same area. The indication area 310 can be set on both sides of the key 345 or at other positions.

[0119] When the door 122 is closed, the front face of the display device 300 passes through the opening 123 of the door 122 , and the indication area 310 , the switch 343 , the transparent plate 342 , the emergency stop button 344 and the key 345 of the display device 300 are all exposed in the opening 123 .

[0120] The emergency stop button 344 is electrically connected to the elevator safety circuit through a wiring harness to realize the shutdown of the elevator in an emergency state; the conversion switch 343 is electrically connected to the corresponding electronic device 200 through a wiring harness to realize the conversion of different working states of the elevator. It is usually switched to the emergency electric mode when a fault occurs or maintenance occurs. The staff can manually adjust the elevator through the button 345 on the display device 300. The button 345 is electrically connected to the button panel 380 and the display panel 390. The button panel 380 and the display panel 390 are electrically connected to the corresponding electronic device 200 through a wiring harness. The button panel 380 and the display panel 390 can transmit signals to the corresponding electronic device 200 to realize the execution of human-computer interaction instructions.

[0121] By setting an opening 123 in the door body 122 and exposing the indication area 310, the conversion switch 343, the transparent plate 342, the emergency stop button 344 and the key 345 of the display device 300 in the opening 123, it is convenient for the staff to obtain the working status of the electronic device 200 inside the control cabinet through the display device 300 and debug, maintain or replace the electronic device 200.

[0122] During the actual implementation process, as shown in Figures 1, 3, 6-8, the control cabinet also includes a partition 150, which is separated from the back panel 110, and the electronic device 200 is arranged between the partition 150 and the back panel 110, and the display device 300 is installed on the partition 150.

[0123] As shown in Figures 1, 3, 6-8, the partition 150 is arranged parallel to the back panel 110, and the two are arranged spaced apart. One end of the partition 150 is connected to the mounting bracket of the electronic device 200, and the other end of the partition 150 is connected to the first side panel 1211 of the casing 120, that is, the partition 150 is supported and fixed by the mounting bracket of the electronic device 200 and the first side panel 1211 of the casing 120.

[0124] As shown in Figures 1, 3, 6-8, the electronic devices 200 are all installed on the side of the back panel 110 close to the housing 120 and are located on the back of the partition 150. The control cabinet also includes a gateway 370, and the display device 300 and the gateway 370 are both installed on the partition 150.

[0125] During the actual implementation process, the staff can obtain the working status of the electronic device 200 and debug, maintain or replace the electronic device 200 through the exposed display device 300; if the gateway 370 fails, the staff can repair the gateway 370 after opening the door body 122.

[0126] By setting up the partition 150, the devices in the control cabinet that need to be frequently debugged and operated can be installed on the partition 150, so that the staff can directly operate them outside the control cabinet, or only need to open the door body 122 to operate the devices. The operation is convenient and simple. At the same time, the partition 150 can isolate the electronic device 200 from the external environment to prevent dust or other impurities from entering the electronic device 200 and affecting the operation of the electronic device 200 when the door body 122 is opened to operate the display device 300 or the gateway 370.

[0127] In some embodiments, as shown in FIG. 11 to FIG. 15 , the display device 300 includes a PCB board 320 , a plurality of light guides 330 , and a housing 340 .

[0128] As shown in Figures 11 to 15, a plurality of indicator lights 321 are provided on the PCB board 320, and the plurality of indicator lights 321 are installed on both sides of the button 345 of the display device 300. The light incident surfaces of the plurality of light guides 330 are arranged opposite to the plurality of indicator lights 321. The light guide 330 can be a columnar structure, and one end face of the columnar light guide 330 is arranged corresponding to the indicator light 321, so that the light emitted by the indicator light 321 can be displayed through the light guide 330.

[0129] As shown in Figures 11 to 15, the shell 340 is provided with an indication area 310, and the shell 340 is provided with a plurality of light guide holes at the position of the indication area 310. The plurality of light guide holes are arranged in a one-to-one correspondence with the plurality of light guide bodies 330, and the other end face of the light guide body 330 protrudes from the outer surface of the light guide hole, or the other end face of the light guide body 330 is flush with the outer surface of the light guide hole.

[0130] The shell 340 is provided with multiple isolation covers 350 on the back side of the indication area 310. The multiple isolation covers 350 define multiple isolation cavities 351. Each light guide 330 is installed with an isolation cavity 351, and the light-emitting surface of the light guide 330 faces the indication area 310. Each isolation cover 350 can define one or more isolation cavities 351.

[0131] As shown in Figures 11 to 15, the isolation cover 350 as a whole can be a rectangular structure, or a circular structure or other shape structures. The end surface of the isolation cover 350 close to the PCB board 320 is recessed inward and provided with a groove, and the groove forms an isolation cavity 351. The light guide hole is provided on the bottom surface of the groove. The groove can be a rectangular groove, or a circular groove or a groove of other shapes.

[0132] During the actual implementation process, when installing the light guide 330, the light guide 330 is inserted into the isolation cavity 351 of the isolation cover 350, and the light-emitting surface of the light guide 330 is set in the corresponding light-guiding hole, the PCB board 320 is installed inside the shell 340, and the indicator light 321 on the PCB board 320 is set corresponding to the light-incident surface of the light guide 330. When the indicator light 321 is turned on, the light source diverges from the light-incident surface of the light guide 330 to the light-emitting surface of the light guide 330. At this time, the staff can directly observe the light color and status of the indicator light 321 outside the shell 340.

[0133] According to the display device 300 of the control cabinet provided in the embodiment of the present application, by providing an isolation cover 350 and an isolation cavity 351, the wall surface of the isolation cavity 351 can be used to separate two adjacent light guides 330, and the light-emitting surfaces of the two adjacent light guides 330 do not interfere with each other, thereby reducing the possibility of cross-talk between the two adjacent light guides 330.

[0134] In some embodiments, as shown in FIG. 11 to FIG. 15 , end surfaces of the plurality of isolation covers 350 facing away from the indication area 310 are flush with each other.

[0135] As shown in Figures 11 to 15, the wall height of the isolation cavity 351 is greater than or equal to the height of the light guide 330, that is, the light guide 330 after installation is completely located in the isolation cavity 351, and if one isolation cover 350 defines multiple isolation cavities 351, then two adjacent light guides 330 are separated by the wall of the isolation cavity 351.

[0136] As shown in Figures 11 to 15, the end surfaces of the multiple isolation covers 350 facing away from the indication area 310 can be flush with the end surfaces of the PCB board 320 facing the isolation cover 350. That is, after the PCB board 320 and the light guide 330 are installed, the end surfaces of the isolation covers 350 facing away from the indication area 310 are aligned with the end surfaces of the PCB board 320 facing the isolation cover 350. At this time, the light guide 330 is completely separated by the isolation cover 350.

[0137] By setting the end faces of multiple isolation covers 350 facing away from the indication area 310 to be flush with each other, the isolation covers 350 and the PCB board 320 can cooperate to separately wrap the multiple light guides 330, that is, the multiple light guides 330 are respectively set in a separate area, further avoiding cross-light between two adjacent light guides 330.

[0138] In some embodiments, as shown in Figures 11 to 15, the display device 300 also includes a plurality of connecting members 360, the connecting members 360 have a first mounting structure 361 and a plurality of mounting positions, each light guide 330 is installed with a mounting position, each isolation cover 350 has a plurality of isolation cavities 351, the plurality of connecting members 360 correspond one-to-one to the plurality of isolation covers 350, the shell 340 is provided with a plurality of second mounting structures 341, and the first mounting structure 361 is connected to the second mounting structure 341.

[0139] As shown in Figures 11 to 15, each connecting member 360 has a first mounting structure 361 and multiple mounting positions, and each isolation cover 350 has multiple isolation cavities 351 along the height direction of the shell 340. The number of mounting positions is the same as the number of isolation cavities 351. For example, if the isolation cover 350 has 4 isolation cavities 351, the connecting member 360 also has 4 mounting positions. The isolation cover 350 can also have multiple isolation cavities 351 along the length direction of the shell 340 or other directions.

[0140] During the actual implementation process, the four light guides 330 are installed one-to-one with the four mounting positions on the same connecting member 360, and the four light guides 330 installed on the same connecting member 360 are installed one-to-one with the four isolation cavities 351 of the same isolation cover 350. The connecting member 360 is connected to the second mounting structure 341 on the shell 340 through the first mounting structure 361.

[0141] By configuring each isolation cover 350 to have multiple isolation cavities 351 and multiple mounting positions on the connector 360 , multiple light guides 330 can be mounted on the housing 340 via one connector 360 , which facilitates operation and improves installation efficiency.

[0142] In some embodiments, as shown in Figures 11-15, the connecting member 360 includes a connecting rib 362, and multiple mounting positions and the first mounting structure 361 are connected through the connecting rib 362. Each isolation cavity 351 in the isolation cover 350 is provided with an avoidance opening 352, and the connecting rib 362 passes through the avoidance opening 352.

[0143] As shown in Figures 11 to 15, multiple installation positions are spaced apart along the length direction of the shell 340, and multiple connecting ribs 362 are also spaced apart along the length direction of the shell 340. The isolation cavity 351 is provided with an avoidance opening 352 on the end face close to the second installation structure 341.

[0144] When installing the connecting piece 360 ​​and the light guide 330, multiple light guides 330 are installed in a one-to-one correspondence with multiple mounting positions. After installing the light guide 330 and the mounting position, the light guide 330 is inserted into the isolation cavity 351. At the same time, multiple connecting ribs 362 are installed in a one-to-one correspondence with the avoidance openings 352 of multiple isolation cavities 351. When the assembly is completed, one end of the connecting rib 362 connected to the mounting position is located inside the isolation cavity 351, and one end of the connecting rib 362 connected to the first mounting structure 361 passes through the avoidance opening 352 and is arranged on the outside of the isolation cover 350.

[0145] By providing the connecting ribs 362 , the fixing reliability of the light guide 330 can be improved, and the strength of the connecting member 360 can be enhanced.

[0146] In some embodiments, as shown in FIG. 11 to FIG. 15 , the width of the avoidance opening 352 gradually decreases in a direction approaching the indication area 310 .

[0147] Among them, as shown in Figures 11 to 15, the avoidance opening 352 can be presented as a trapezoidal structure as a whole, or it can be presented as a V-shaped or other shape structure. The upper bottom of the trapezoidal avoidance opening 352 is set close to the indication area 310, and the lower bottom of the trapezoidal avoidance opening 352 is set away from the indication area 310. The minimum width of the avoidance opening 352 can be less than or equal to the width of the connecting rib 362.

[0148] During the actual implementation process, when installing the connecting member 360, the connecting member 360 is moved so that the connecting rib 362 moves from the end of the avoidance opening 352 away from the indication area 310 to the end of the avoidance opening 352 close to the indication area 310, that is, the connecting rib 362 moves from the end of the avoidance opening 352 with a larger width to the end of the avoidance opening 352 with a smaller width. When the connecting rib 362 is located at the position where the width of the avoidance opening 352 is the smallest, since the width of the connecting rib 362 is greater than or equal to the minimum width of the avoidance opening 352, the connecting rib 362 is clamped by the two side walls of the avoidance opening 352 at this time.

[0149] By setting the width of the avoidance opening 352 to gradually decrease in the direction approaching the indication area 310, the movement of the connecting rib 362 can be facilitated when the connecting rib 362 is at a position where the width of the avoidance opening 352 is larger, and when the connecting rib 362 is at a position where the width of the avoidance opening 352 is smallest, the two side walls of the avoidance opening 352 can be used to clamp the connecting rib 362, thereby improving the fixing reliability of the connecting rib 362.

[0150] In some embodiments, as shown in FIG. 11 to FIG. 15 , a cavity wall of the isolation cavity 351 is provided with a limiting groove 353 , and an outer wall of the mounting position cooperates with the limiting groove 353 .

[0151] Among them, as shown in Figures 11 to 15, the shape of the limiting groove 353 is the same as the shape of the corresponding part of the outer wall of the mounting position, and the width of the outer wall of the mounting position is greater than the width of the isolation cavity 351. When the light guide 330 is installed in the isolation cavity 351, the mounting position and the light guide 330 are installed in the isolation cavity 351 together. The setting of the limiting groove 353 allows the mounting position to be completely located in the isolation cavity 351, and at the same time, the outer wall of the mounting position fits with the inner wall of the limiting groove 353.

[0152] By setting the limiting groove 353, while ensuring that the installation position can be installed in the isolation cavity 351, the limiting groove 353 can limit the freedom of the installation position in the height direction of the shell 340, thereby limiting the freedom of the light guide 330 to avoid the light guide 330 from tilting during the installation process.

[0153] In some embodiments, as shown in Figures 11-15, the connecting rib 362 includes a connecting main section 3621 and multiple connecting branch sections 3622. The connecting main section 3621 extends along the distribution direction of the multiple isolation cavities 351 of the isolation cover 350 and is located outside the isolation cavity 351. The first mounting structure 361 is provided on the connecting main section 3621; the multiple connecting branch sections 3622 are spaced apart and connected to the connecting main section 3621, and each connecting branch section 3622 is provided with a mounting position at one end facing away from the connecting main section 3621, and the connecting branch section 3622 passes through the avoidance opening 352.

[0154] As shown in Figures 11 to 15, the main connecting section 3621 extends from the first mounting structure 361 to both sides along the height direction of the shell 340, the connecting branch section 3622 is arranged along the length direction of the shell 340, and one end of the connecting branch section 3622 is connected to the main connecting section 3621, and the other end of the connecting branch section 3622 is provided with a mounting position, and multiple connecting branch sections 3622 are spaced apart along the extension direction of the main connecting section 3621.

[0155] By setting the above-mentioned connecting main section 3621 and connecting branch section 3622, sufficient space can be provided for the installation of multiple light guides 330, and at the same time the strength of the connecting member 360 can be further improved, thereby further improving the fixing reliability of the light guide 330.

[0156] In some embodiments, as shown in FIG. 11 to FIG. 15 , the second mounting structure 341 includes a mounting post disposed adjacent to the isolation cover 350 , and the first mounting structure 361 includes a mounting hole, through which the mounting post passes.

[0157] As shown in Figures 11 to 15, a mounting column is provided on the inner side of the shell 340 next to the end face of each isolation cover 350 having the avoidance opening 352, and the second mounting structure 341 also includes a plurality of support members arranged on the outer periphery of the mounting column, and the height of the support member is the same as the distance from the inner surface of the shell 340 to the bottom of the limiting groove 353.

[0158] As shown in Figures 11 to 15, the mounting hole is set on the connecting member 360. When connecting the first mounting structure 361 and the second mounting structure 341, the mounting hole is moved toward the mounting column so that the end of the mounting column that is not connected to the shell 340 is inserted into the mounting hole. The mounting hole is continued to be moved until the mounting hole is close to the end face of the shell 340 and fits with the support member. At this time, the connecting member 360 as a whole is parallel to the shell 340.

[0159] The first mounting structure 361 is set as a mounting hole, and the second mounting structure 341 is set as a mounting column. The mounting method is simple and the structure is simple, which can improve the installation efficiency of the display device 300 to a certain extent. By setting the support member, the connecting member 360 can be kept in a balanced state as a whole, thereby further avoiding the light guide 330 from being skewed.

[0160] In some embodiments, as shown in FIG. 11 to FIG. 15 , the connector 360 has a plurality of sleeves 363 , and the sleeves 363 define installation positions.

[0161] As shown in Figures 11 to 15, each connecting branch section 3622 has a sleeve 363 at one end away from the connecting main section 3621, and a through hole is provided inside the sleeve 363 along the height direction of the sleeve 363. The through hole is an installation position, and the diameter of the through hole can be slightly larger than or equal to the diameter of the light guide 330.

[0162] When installing the light guide 330 at the installation position, the light guide 330 is inserted into the through hole of the sleeve 363 , and the entire sleeve 363 is located in the middle of the light guide 330 .

[0163] By using the sleeve 363 to define the installation position, the structure is simple and the installation reliability is high. The operation of installing the light guide 330 is simple, thereby further improving the installation efficiency of the display device 300.

[0164] The following describes in detail the arrangement of the electronic components 200 in the control cabinet of the embodiment of the present application.

[0165] In some embodiments, as shown in FIG. 2 , FIG. 5 - FIG. 8 , and FIG. 16 - FIG. 19 , the control cabinet includes a cabinet body 100 , a power board assembly 210 , a drive board assembly 230 , and a module board assembly 220 .

[0166] 2 , 5 - 8 , and 16 - 19 , the cabinet 100 includes a housing 120 and a back panel 110 of any one of the above-mentioned embodiments, and the electronic device 200 includes a power board assembly 210 , a drive board assembly 230 , and a module board assembly 220 . The power board assembly 210 , the drive board assembly 230 , and the module board assembly 220 are arranged sequentially along a first direction, and the first direction is parallel to the back side (back panel 110 ) of the cabinet 100 . For example, the first direction is parallel to the length direction of the back panel 110 , and the power board assembly 210 , the drive board assembly 230 , and the module board assembly 220 are arranged sequentially from bottom to top along the length direction of the back panel 110 .

[0167] By directly arranging the power board assembly 210, the drive board assembly 230 and the module board assembly 220 in the cabinet 100, the power board assembly 210, the drive board assembly 230 and the module board assembly 220 can be appropriately installed according to the shape and internal space of the control cabinet. Compared with installing an independent inverter in the cabinet 100, the space utilization rate is higher and the shape of the control cabinet is not restricted. At the same time, the power board assembly 210, the drive board assembly 230 and the module board assembly 220 are arranged in sequence in a direction parallel to the back panel 110 to achieve a flat layout, which can reduce the overall thickness of the electronic device 200 and thus can be suitable for scenarios in narrow spaces. In addition, the power board assembly 210, the drive board assembly 230 and the module board assembly 220 can be assembled separately and then assembled together, which is simple to assemble.

[0168] According to the control cabinet provided in the embodiment of the present application, the space utilization of the control cabinet can be improved, the overall size of the control cabinet can be reduced, the assembly is simple, and the scope of application of the control cabinet can be expanded through the arrangement of the power board assembly 210, the drive board assembly 230 and the module board assembly 220.

[0169] In some embodiments, as shown in Figures 2, 5-8, and 16-19, the electronic device 200 includes a main control board assembly 240, which is arranged parallel to and spaced apart from the driving board assembly 230, and the main control board assembly 240 is arranged on the side of the driving board assembly 230 facing away from the back plate 110.

[0170] As shown in Figures 2, 5-8, and 16-19, the main control board assembly 240 includes a main control board 241 and an electronic device 200 installed on the main control board 241, the drive board assembly 230 includes a drive board 231 and a pre-charging board 232, the power board assembly 210 includes a power board 213 and a capacitor board 212, and the module board assembly 220 includes a module board 221 and a radiator 222.

[0171] As shown in Figures 2, 5-8, and 16-19, the control cabinet can be divided into a drive part, a control part, a power supply part, and a human-computer interaction part according to the working principle. The drive board assembly 230, the module board assembly 220, and the capacitor plate 212 in the power board assembly 210 constitute the drive part; the main control board assembly 240 and the UCMP board 391 in the display device 300 constitute the control part; the power board 213 in the power board assembly 210 constitutes the power supply part; and the part of the display device 300 other than the UCMP board 391 constitutes the human-computer interaction part.

[0172] As shown in Figures 2, 5-8, and 16-19, the power supply part takes power from the input three-phase AC power of the driving board 231 and converts it into power of various voltage levels to power various parts within the driving board assembly 230.

[0173] As shown in Figures 2, 5-8, and 16-19, the control part draws power from the power supply part through a wiring harness. The main control board 241 is the core of the control part. The main control board 241 controls the drive part to realize the elevator traction machine to drive the car to rise, fall, stop opening the door, and other control functions such as stability and shock absorption.

[0174] The UCMP board 391 in the control part is connected to the elevator safety circuit, car, and main control board 241 through a wiring harness to realize the early door opening function: when the elevator enters the door area during normal operation, the normally open contact of the relay is closed, and the door lock 1222 circuit is short-circuited until the elevator reaches the floor, releasing all output contactors, completing the early door opening function, and improving the door opening efficiency.

[0175] UCMP board 391 can also realize the car accidental movement protection function: when the car moves unexpectedly or the car leaves the exit area, the DZ7_EN signal or DZ8_EN signal is invalid, the relay coil loses power, its normally open contact is disconnected, the door lock 1222 circuit is disconnected, and the elevator stops running.

[0176] UCMP board 391 can also realize the re-leveling function: when the elevator runs to the leveling position and opens the door, for example, due to the change of the load in the car, the car moves up or down. When the system detects that the car movement distance exceeds a certain value, generally 10mm-20mm, the system executes the re-leveling function.

[0177] The UCMP board 391 can also implement the short-circuit detection function of the car door or hall door: when the door is open, the MCU (Microcontroller Unit) controls the action of the UCMP board 391 and determines the corresponding short-circuit position through the front door lock 1222 detection, the rear door lock 1222 detection, and the main door lock 1222 detection.

[0178] The main control board assembly 240 and the drive board assembly 230 are arranged parallel and spaced relative to each other along the width direction of the shell 340. The drive board assembly 230 is installed on the side of the back plate 110 close to the housing 120, and the main control board assembly 240 is installed on the side of the drive board assembly 230 away from the back plate 110. The main control board assembly 240 is connected to the drive board assembly 230 through the main control bracket 242.

[0179] Since the overall thickness of the driving board assembly 230 is relatively small, the main control board assembly 240 and the driving board assembly 230 are arranged parallel and spaced apart from each other along the width direction of the housing 340 to improve the space utilization inside the cabinet 100 .

[0180] In some embodiments, as shown in Figures 2, 5-8, and 16-19, the power board assembly 210 is arranged parallel to the back side (back panel 110) of the cabinet 100, the drive board assembly 230 is arranged parallel to the back side (back panel 110) of the cabinet 100, and the module board assembly 220 is arranged vertically relative to the back side (back panel 110) of the cabinet 100.

[0181] Among them, as shown in Figures 2, 5-8, and 16-19, the power board assembly 210, the drive board assembly 230 and the module board assembly 220 are arranged sequentially from the upper end to the lower end of the back plate 110, the drive board assembly 230 is arranged parallel to the back plate 110, and the main control board assembly 240 is arranged parallel to the drive board 231, that is, the main control board assembly 240 is also arranged parallel to the back plate 110.

[0182] By arranging the power board assembly 210 and the drive board assembly 230 parallel to the back panel 110, the overall thickness of the electronic device 200 can be reduced, a flat layout can be achieved, and the overall volume of the cabinet 100 can be reduced, so that the cabinet 100 can be suitable for use in a narrow space. By arranging the module board assembly 220 vertically relative to the back panel 110, since the overall volume of the module board assembly 220 is larger and there are fewer electronic devices 200, the module board assembly 220 can provide a certain support force for the drive board assembly 230 and the main control board assembly 240.

[0183] In some embodiments, as shown in Figures 2, 5-8, and 16-19, the drive plate assembly 230 includes a drive plate 231 and a pre-charging plate 232. The pre-charging plate 232 is arranged parallel to the drive plate 231 and is arranged on the side of the drive plate 231 facing away from the back side (back plate 110) of the cabinet 100.

[0184] Among them, the cross-sectional area of ​​the driving plate 231 is larger than the cross-sectional area of ​​the pre-charging plate 232, and the pre-charging plate 232 is installed on the side of the driving plate 231 facing away from the back plate 110, that is, the pre-charging plate 232 and the driving plate 231 are stacked in the width direction of the cabinet 100, and the pre-charging plate 232 is electrically connected to the driving plate 231 through positive and negative copper studs.

[0185] By stacking the pre-charging board 232 and the driving board 231, the space utilization of the control cabinet can be improved. At the same time, the pre-charging board 232 and the driving board 231 are hard-connected through copper terminals, which has higher reliability than the wiring harness connection.

[0186] In some embodiments, as shown in Figures 2, 5-8, and 16-19, the arrangement height of the drive board 231 relative to the back side (back panel 110) of the cabinet 100 is lower than the arrangement height of the power board assembly 210 relative to the back side of the cabinet 100.

[0187] 2 , 5 - 8 , and 16 - 19 , the power board 213 and the capacitor plate 212 of the power board assembly 210 are arranged at a higher height relative to the back plate 110 than the drive board 231 is arranged at a higher height relative to the back plate 110. The upper end of the pre-charging plate 232 is electrically connected to the capacitor plate 212 through positive and negative copper terminals, and the lower end of the pre-charging plate 232 is electrically connected to the drive board 231 through positive and negative copper terminals, that is, the capacitor plate 212, the pre-charging plate 232, and the drive board 231 are stacked.

[0188] By stacking the capacitor plate 212, the pre-charging plate 232 and the driving plate 231, the problem that the driving plate 231 cannot accommodate the pre-charging plate 232 in a small volume can be effectively solved, thereby improving the space utilization of the control cabinet. At the same time, the capacitor plate 212, the pre-charging plate 232 and the driving plate 231 are hard-connected through copper studs, which can improve the overall connection reliability.

[0189] In some embodiments, as shown in Figures 2, 5-8, and 16-19, the main circuit terminal 233 of the drive board assembly 230 is arranged on a side close to the module board assembly 220, and the main circuit terminal 233 of the drive board assembly 230 is connected to the module board assembly 220 through a rigid connector 360.

[0190] The main circuit terminal 233 is a copper terminal, and the rigid connector 360 may be a welding pin, through which the copper terminal is welded to the module board 221 of the module board assembly 220 .

[0191] As shown in Figures 2, 5-8, and 16-19, the main working principle of the driving part is: R, S, T, N three-phase alternating current and the neutral line are input from the terminal block of the driving board 231, and N is connected in parallel with any one of the phases R, S, and T to obtain a 220V voltage to supply power to the power supply board 213. The three-phase alternating current then flows through the module board 221 through the copper terminals R, S, and T, and is rectified into direct current by the rectifier chip on the module board 221; and then flows through the pre-charging board 232 through the positive and negative copper bars. The pre-charging board 232 mainly protects the entire circuit when the control cabinet is started. At the same time, the pre-charging board 232 is connected in parallel with the capacitor plate 212 through the positive and negative copper studs on the upper part. The main function of the capacitor plate 212 is to discharge the Reduce voltage fluctuations to reduce harmonics. On the other hand, the positive and negative copper studs at the bottom are electrically connected to the driver board 231, and then the positive and negative busbars are output through the positive and negative terminal blocks of the driver board 231. Then the circuit passes through the positive and negative copper bars from the pre-charging board 232. The negative copper bar has a common input and output and is connected in parallel with the positive copper bar. Then it flows through the module board 221, and the DC power is inverted into three-phase AC power through the inverter chip of the module board 221; then it passes through the copper terminals U, V, and W, and flows through the U terminal block, V terminal block, and W terminal block on the upper part of the driver board 231 for output; the B-phase current flows out from the brake chip on the module board 221, passes through the copper terminal B, and flows through the driver board 231 and is output through the B terminal block at the bottom of the driver board 231.

[0192] By connecting the main circuit terminal 233 of the driving part to the module board 221 using the rigid connector 360 , the reliability of the connection between the driving board 231 and the module board 221 can be improved.

[0193] In some embodiments, as shown in Figures 20-22, the electronic device 200 includes a first circuit board and a second circuit board arranged in parallel and spaced apart, and the control cabinet also includes a connecting plate 400, which is arranged vertically relative to the first circuit board, and the first circuit board and the second circuit board are electrically connected through the connecting plate 400.

[0194] As shown in Figures 20-22, the electronic device 200 includes a main control board assembly 240 and a power board assembly 210, a drive board assembly 230 and a module board assembly 220 arranged in sequence along a first direction.

The first end of the connecting board 400 is connected to the main control board 241 , and the second end is connected to the driving board 231 .

[0196] The first circuit board and the second circuit board are electrically connected via the connecting plate 400, which has higher reliability than connection via a wiring harness, and occupies less space than connection using only a hard connector, and has a simple structure and a simple connection method.

[0197] In some embodiments, as shown in Figures 20-22, one of the first end of the connecting plate 400 and the first circuit board is provided with a female socket 2411, and the other is provided with a bent angle male socket 410 plugged into the female socket 2411, and the second end of the connecting plate 400 is provided with a bent foot soldering pin, which is soldered to the second circuit board.

[0200] The connecting plate 400 is connected to the main control board 241 and the driving board 231 respectively through the angled male socket 410 and the angled welding pin 420. While realizing the electrical connection between the main control board 241 and the driving board 231, the main control board 241 and the driving board 231 can be connected through a hard connection, and the connection reliability is high.

[0201] In some embodiments, as shown in Figures 6-8, 16 and 17, at least part of the electronic device 200 and the housing 120 and / or the back panel 110 define at least two air ducts, and the housing 120 is provided with heat dissipation holes 1215 in the area opposite to the air ducts.

[0202] 6-8, 16 and 17, some electronic devices 200 can define at least two air ducts with the housing 120, some electronic devices 200 can define at least two air ducts with the back panel 110, and some electronic devices 200 can define at least one air duct with the housing 120 and the back panel 110 respectively.

The first fan 1216 and the second fan 1217 are respectively arranged in one-to-one correspondence with at least two air ducts.

[0203] By providing the air duct and the corresponding heat dissipation holes 1215 , the heat dissipation effect of the control cabinet can be improved, the use safety of the electronic components 200 in the control cabinet can be ensured, and damage to the electronic components 200 caused by excessive temperature can be avoided.

[0204] In some embodiments, as shown in Figures 6-8, 16 and 17, the electronic device 200 includes: a power board assembly 210 and a module board assembly 220 arranged sequentially along a first direction, the first direction is parallel to the back panel 110, the power board assembly 210 is arranged parallel to the back panel 110, the module board assembly 220 is arranged vertically relative to the back panel 110, the power board assembly 210 and the back panel 110 define a first air duct 250, and the module board assembly 220, the back panel 110 and the casing 120 define a second air duct 260.

[0205] Among them, as shown in Figures 6 to 8, 16 and 17, the power board assembly 210 is arranged parallel to the back panel 110, and the width of the first air duct 250 defined by the power board assembly 210 and the back panel 110 is larger. The module board assembly 220 is arranged vertically to the back panel 110, and the height of the second air duct 260 defined by the module board assembly 220, the back panel 110 and the casing 120 is larger. The air in the first air duct 250 is made to flow through the first fan 1216, and the air in the second air duct 260 is made to flow through the second fan 1217.

[0206] A first air duct 250 is defined by the power board assembly 210 and the back panel 110, and a second air duct 260 is defined by the module board assembly 220, the back panel 110 and the housing 120. The first air duct 250 and the second air duct 260 can respectively dissipate heat for different electronic devices 200, thereby expanding the heat dissipation area of ​​the first air duct 250 and the second air duct 260 and improving the heat dissipation effect.

[0207] In some embodiments, as shown in Figures 6-8, 16 and 17, the power board assembly 210 includes a power board 211, a capacitor board 212 and a power board 213, the power board 211 is installed on the cabinet 100; the capacitor board 212 is installed on the power board 211, and the power board 211, the capacitor board 212 and the cabinet 100 define a first air duct 250; the power board 213 is installed on the side of the capacitor board 212 away from the power board 211, and the back of the power board 213 faces the capacitor board 212.

[0208] 6-8, 16 and 17, the end face of the power board 213 provided with the electronic device 200 is the front face, and the opposite end face is the back face. The capacitor plate 212 and the power board 213 are both arranged parallel to the back plate 110, and the capacitor plate 212 and the power board 213 are spaced apart. The power board 213 is arranged on the side of the capacitor plate 212 away from the back plate 110. The two power supply brackets 211 are respectively connected to the capacitor plate 212 and the power board 213 on both sides of the length direction of the back plate 110. There is a certain gap between the two power supply brackets 211, and the electronic device 200 mounted on the capacitor plate 212 is located between the two power supply brackets 211.

[0209] As shown in Figures 6 to 8, 16 and 17, the space formed by the capacitor plate 212, the two power supply brackets 211 and the backplane 110 is the first air duct 250. The air in the first air duct 250 is made to flow through the first fan 1216, thereby dissipating heat for the electronic device 200 located in the first air duct 250.

[0210] A first air duct 250 is defined by the power supply bracket 211, the capacitor plate 212 and the cabinet 100, and the first fan 1216 can be used to dissipate heat from the electronic device 200 on the capacitor plate 212. At the same time, the back of the power supply board 213 faces the capacitor plate 212, which can reduce the distance between the power supply board 213 and the capacitor plate 212, so that the heat of the electronic device 200 on the power supply board 213 can be transferred to the capacitor plate 212 and dissipated by the first fan 1216. This can ensure the heat dissipation effect while reducing the number of first fans 1216.

[0211] In some embodiments, as shown in Figures 6-8, 16 and 17, the module board assembly 220 includes a module board 221, a radiator 222 and a module board bracket 223, the front of the module board 221 faces the drive board assembly 230; the radiator 222 is arranged on the back of the module board 221; the module board 221 is installed on the cabinet 100 through the module board bracket 223, and the module board bracket 223 is provided with an avoidance hole for the radiator 222 to pass through, the module board bracket 223 and the cabinet 100 define a second air duct 260, and the module board bracket 223 separates the module board 221 from the second air duct 260.

[0212] 6-8, 16 and 17, the module board 221 has the end face of the electronic device 200 as the front, the front of the module board 221 is arranged toward the drive board assembly 230, and the back of the module board 221 is spaced apart from the module board bracket 223. The module board bracket 223 can be an inverted L-shaped structure or other shape structures. The upper end of the module board bracket 223 is used to be connected to the partition 150, and the lower end of the module board bracket 223 is connected to the back panel 110.

[0213] As shown in Figures 6 to 8, 16 and 17, the substrate of the radiator 222 is fitted against the back of the module board 221, and the fins of the radiator 222 are mounted on the side of the module board bracket 223 away from the module board 221. When the housing 120 is connected to the back panel 110, the housing 120 is parallel to the module board 221 and close to the inner wall surface of the module board 221, the module board bracket 223, and the fins of two adjacent radiators 222 form a second air duct 260. At this time, the second air duct 260 is separated from the module board 221 by the module board bracket 223, and the second fan 1217 is used to make the air in the second air duct 260 flow, thereby reducing the heat on the module board 221.

[0214] The second air duct 260 is defined by the module board bracket 223 and the cabinet 100, which can dissipate heat for the electronic components 200 on the module board 221 to ensure the heat dissipation effect. The module board 221 and the second air duct 260 are separated by the module board bracket 223 to form an independent second air duct 260, thereby avoiding dust accumulation on the module board 221 and reduced service life of the module board 221 caused by the air flow in the second air duct 260.

[0215] In some embodiments, as shown in FIG. 6 to FIG. 8 , FIG. 16 and FIG. 17 , the power board assembly 210 and the module board assembly 220 are respectively arranged at two ends of the back plate 110 that are away from each other in the first direction.

[0216] 6-8, 16 and 17, the first direction is a direction parallel to the back panel 110, the power board assembly 210 and the first air duct 250 defined therein are arranged at the first end of the back panel 110 in the first direction, and the module board assembly 220 and the second air duct 260 defined therein are arranged at the second end of the back panel 110 in the first direction.

[0217] By arranging the power board assembly 210 and the module board assembly 220 at the two ends of the back plate 110 that are separated in the first direction, the heat sources can be kept away from each other to avoid further temperature increase caused by the heat sources being too close. At the same time, the first air duct 250 and the second air duct 260 can be kept away from each other to form two independent heat dissipation ducts, thereby improving the heat dissipation efficiency.
