[0035] The principles and features of the present application are described below with reference to the accompanying drawings. The examples given are only used to explain the present application and are not intended to limit the scope of the present application.

[0036] As Figures 1 to 3As shown, the embodiment of the present application proposes an elevator control cabinet 10, which includes a first bracket 100 and a driving module 200. The first bracket 100 has a first mounting surface 101. The driving module 200 includes a driving board 210, a capacitor plate 220, and a pre-charging board 230. At least one first conductive connector 211 is provided on the driving board 210. The pre-charging board 230 is electrically connected to the driving board 210 through the first conductive connector 211. The pre-charging board 230 and the driving board 210 are both fixedly connected to the first mounting surface 101. The capacitor plate 220 is electrically connected to the driving board 210 and is fixedly connected to the first bracket 100. At least a portion of the capacitor plate 220 is located on a side of the first bracket 100 away from the driving board 210.

[0037] In the present application, the first bracket 100 is a mounting substrate of the driving module 200. The first bracket 100 having the first mounting surface 101 means that the first bracket 100 is plate-shaped, and the first mounting surface 101 of the first bracket 100 is a plate-shaped surface in the thickness direction thereof. Usually, the elevator control cabinet 10 also includes a housing 300, and the housing 300 has a receiving cavity 301 inside, and the first bracket 100 is installed in the receiving cavity 301 of the housing 300.

[0038] The driving module 200 includes a driving board 210, a capacitor plate 220 and a pre-charge plate 230. The driving board 210 is a core component of the driving module 200. A variety of circuits can be arranged on the driving board 210, such as a main circuit, an inverter circuit, a rectifier circuit, etc. The driving board 210 is also provided with a plurality of power components such as a rectifier component, an inverter component, etc. The capacitor plate 220 and the pre-charge plate 230 are both electrically connected to the driving board 210. The driving board 210 can be externally connected to an external three-phase alternating current, and the three-phase alternating current is converted into a two-phase direct current through the rectifier circuit of the driving board 210. The two-phase direct current and the capacitor on the capacitor plate 220 are connected in parallel and then flow through the inverter circuit on the driving board 210 to be converted into a three-phase alternating current. The three-phase alternating current returns to the output end of the wiring terminal of the driving board 210, and then is supplied to the elevator traction machine through the transmission wire to drive the elevator traction machine to run. The capacitor plate 220 is used to filter and smooth the DC voltage to ensure the quality of the DC voltage. The pre-charging board 230 can protect the entire circuit and prevent excessive charging current to the power components when the high voltage is powered on.

[0039] At least one first conductive connecting member 211 is provided on the driving board 210 , which means that the number of the first conductive connecting members 211 may be one or more, and the present application does not impose any limitation on this.

[0040] The elevator control cabinet 10 of the present application, the driving plate 210, the pre-charging plate 230 and the capacitor plate 220 are all fixedly connected to the first bracket 100, so that the above-mentioned multiple components form a modular whole. In addition, the pre-charging plate 230 and the driving plate 210 are located on the first mounting surface 101 of the first bracket 100, and at least part of the capacitor plate 220 is located on the side of the first bracket 100 away from the driving plate 210, so that the space of the first bracket 100 can be reasonably utilized. In this way, it is conducive to improving the degree of integration of the internal structure of the elevator control cabinet 10, and then it is conducive to realizing the miniaturization demand of the elevator control cabinet 10. In addition, the pre-charging plate 230 is electrically connected to the driving plate 210 through the first conductive connector 211, and the first conductive connector 211 can withstand a large current, so that the reliability of the electrical connection between the two can be improved while ensuring the convenience of the connection between the two. As a result, the above-mentioned integrated structure can be applied to the elevator control cabinet 10 with a power of 45kw to 55kw. Furthermore, at least a portion of the capacitor plate 220 is disposed on the side of the first bracket 100 away from the drive plate 210, so that the heat generated by the capacitor plate 220 has less impact on the drive plate 210 and the pre-charging plate 230, thereby ensuring the normal operation of the drive plate 210 and the pre-charging plate 230, and further helping to improve the reliability and life of the elevator control cabinet 10.

[0041] It should be noted that the drive board 210, the pre-charge board 230 and the capacitor board 220 are all PCB boards (Printed Circuit Board), and various power components and control circuits are directly arranged on the printed circuit board. For example, the drive board 210 is a structure integrating a rectifier circuit, an inverter circuit, a rectifier bridge component, an IGBT component (Insulated Gate Bipolar Transistor, insulated gate bipolar transistor) and the like on the PCB circuit board, the capacitor board 220 is a structure integrating an electrolytic capacitor 222, a connection terminal and the like on the PCB circuit board, and the pre-charge board 230 is a structure integrating a pre-charge resistor, a charging circuit and the like on the PCB circuit board.

[0042] In addition, at least a portion of the capacitor plate 220 is located on the side of the first bracket 100 away from the driving board 210, which means that the entire capacitor plate 220 can be located on the side of the first bracket 100 away from the driving board 210; or, a portion of the capacitor plate 220 is located on the side of the first bracket 100 away from the driving board 210, which can be determined according to the electrical connection method between the capacitor plate 220 and the driving board 210.

[0043] For example, in some embodiments, the capacitor plate 220 is electrically connected to the driving plate 210 through a wire cable. In this case, the whole of the capacitor plate 220 can be located on the side of the first bracket 100 away from the driving plate 210. That is to say, the capacitor plate 220 and the driving plate 210 are respectively on opposite sides in the thickness direction of the first bracket 100. Or, in other embodiments, as Figure 3 shown, the capacitor plate 220 is electrically connected to the driving plate 210 through the first conductive copper pillar 223. In this case, it is equivalent to the capacitor plate 220 being directly laminated on the driving plate 210. Therefore, a part of the capacitor plate 220 may be located inside the first bracket 100, and another part is located on the side of the first bracket 100 away from the driving plate 210.

[0044] In a specific embodiment, as Figure 3 shown, the capacitor plate 220 includes a capacitor plate body 221 and a plurality of electrolytic capacitors 222 provided on the capacitor plate body 221. The capacitor plate body 221 is electrically connected to the driving plate 210 through the first conductive copper pillar 223. The first bracket 100 is provided with a first avoidance hole 102 for the electrolytic capacitor 222 to pass through. By providing the first avoidance hole 102 on the first bracket 100, a laminated conductive connection between the capacitor plate body 221 and the driving plate 210 is realized, which is beneficial to improving the convenience of the electrical connection between the two. In addition, there is no transition piece between the driving plate 210 and the capacitor plate 220, and the two are directly connected, so that the volume after their electrical connection can also be reduced, which is further beneficial to meeting the miniaturization requirement of the elevator control cabinet 10.

[0045] In some embodiments, as Figure 2 and Figure 3 shown, the driving module 200 further includes a lightning protection board 240. The lightning protection board 240 is electrically connected to the driving plate 210 through the second conductive copper pillar 241. The lightning protection board 240 is used to prevent each component on the driving module 200 from being damaged by a surge voltage, thereby improving the safety and stability of the elevator control cabinet 10. The lightning protection board 240 is electrically connected to the driving plate 210 through the second conductive copper pillar 241. In this way, a laminated conductive connection between the two can be realized, which is beneficial to improving the convenience of the electrical connection between the two. In addition, the volume after their electrical connection can be reduced, which is further beneficial to meeting the miniaturization requirement of the elevator control cabinet 10. Moreover, the lightning protection board 240 can be connected to the second conductive copper pillar 241 of the driving plate 210 by welding, so that both the electrical connection and the fixed connection of the lightning protection board 240 are realized.

[0046] In some embodiments, as Figure 2 and Figure 3As shown, at least one second conductive connector 212 is provided on the drive board 210. The drive module 200 further includes a power connection terminal 250, and the power connection terminal 250 is electrically connected to the drive board 210 through the second conductive connector 212.

[0047] In this embodiment, the drive module 200 further includes a power connection terminal 250. The power connection terminal 250 may include, for example, an AC input terminal and an AC output terminal. The AC input terminal may be three ports R, S, and T, for example, and the AC output terminal may be three ports U, V, and W, for example. The AC output terminal directly supplies power to the elevator traction machine to drive the elevator traction machine to operate.

[0048] In this embodiment, the second conductive connector 212 is used to realize the electrical connection between the power connection terminal 250 and the drive board 210. The second conductive connector 212 can withstand a large energized current, so that while ensuring the convenience of the electrical connection between the power connection terminal 250 and the drive board 210, the reliability of the electrical connection between the two can be improved. Thus, the above integrated structure can be applied to the elevator control cabinet 10 with a power of 45 kw to 55 kw.

[0049] In some embodiments, the first conductive connector 211 is a copper bar. The copper bar has high electrical conductivity, strong corrosion resistance, and is not easily oxidized, which is suitable for electrical connection with large current. In this way, the stability and reliability of the electrical connection between the pre-charge board 230 and the drive board 210 can be improved.

[0050] In some embodiments, the second conductive connector 212 is a copper bar, so that the stability and reliability of the electrical connection between the power connection terminal 250 and the drive board 210 can be improved.

[0051] In some embodiments, as Figure 2 and Figure 4 shown, the first bracket 100 has a second mounting surface (not shown in the figure) opposite to the first mounting surface 101. The first bracket 100 is further provided with a second avoidance hole 103. The drive module 200 further includes a radiator 260. The radiator 260 is mounted on the second mounting surface. At least one IGBT component (not shown in the figure) is provided on the drive board 210. The radiator 260 dissipates heat from the IGBT component through the second avoidance hole 103.

[0052] In this embodiment, a radiator 260 is provided on the second mounting surface of the first bracket 100. That is to say, the radiator 260 and the capacitor board 220 are on the same side, and the drive board 210 and the pre-charge board 230 are on the same side. In this way, the board space of the first bracket 100 can be reasonably utilized, which is conducive to further meeting the miniaturization requirement of the elevator control cabinet 10. Further, the first bracket 100 is further provided with a second avoidance hole 103. At least one IGBT component is provided on the drive board 210, and the radiator 260 dissipates heat from the IGBT component through the second avoidance hole 103. The IGBT component is a modular semiconductor product formed by bridging and encapsulating IGBT (insulated gate bipolar transistor chips) through a specific circuit, and it is integrally arranged on the drive board 210. Specifically, in this embodiment, the IGBT component is arranged on the surface of the drive board 210 close to the first bracket 100, and the first bracket 100 is further provided with a second avoidance hole 103. With such an arrangement, the second avoidance hole 103 can expose the IGBT component, and the radiator 260 can dissipate heat from the IGBT component through the second avoidance hole 103, which is beneficial to improving the heat dissipation effect on the IGBT component.

[0053] It should be noted that the number of IGBT components can be one or more, and this application does not limit this. Further, the radiator 260 can be attached to the IGBT component through a heat-conducting member such as thermal grease or a heat-conducting sheet to dissipate heat from the IGBT component; or, the IGBT component can be directly fixed on the outer surface of the radiator 260 to enable the radiator 260 to dissipate heat from the IGBT component, and this application does not limit this either.

[0054] In some embodiments, as Figure 1 and Figure 2 shown, the elevator control cabinet 10 further includes a housing 300. An accommodation cavity 301 is formed inside the housing 300. The first bracket 100 is arranged in the accommodation cavity 301 to form a heat dissipation air duct 302 on the side of the first bracket 100 facing away from the drive board 210. At least part of the radiator 260 and the capacitor board 220 are located in the heat dissipation air duct 302. The housing 300 is further formed with a first air inlet 303 and a first air outlet 304 that communicate with the heat dissipation air duct 302.

[0055] In this embodiment, the first bracket 100 is disposed in the accommodation cavity 301 of the housing 300. Thus, the first bracket 100 and the housing 300 enclose a heat dissipation air duct 302, and the heat dissipation air duct 302 is located on the side of the first bracket 100 facing away from the drive board 210. The heat dissipation air duct 302 can dissipate heat from at least part of the radiator 260 and the capacitor board 220 alone, which is beneficial to improving the heat dissipation effect on the capacitor board 220 and the IGBT module, and further beneficial to improving the working stability and reliability of the drive module 200. In addition, only the radiator 260 and the capacitor board 220 are provided in the heat dissipation air duct 302, so the volume of the radiator 260 can be appropriately increased, thereby further improving the heat dissipation effect on the IGBT module to ensure the normal operation of the drive module 200.

[0056] In some embodiments, as Figure 1 and Figure 2 shown, the elevator control cabinet 10 further includes a first cooling fan 400, and the first cooling fan 400 is correspondingly disposed at the first air outlet 304 and installed on the housing 300. Thus, the first cooling fan 400 can form forced convection heat dissipation in the heat dissipation air duct 302, which is beneficial to further improving the heat dissipation effect on the capacitor board 220 and the IGBT module.

[0057] In a specific embodiment, as Figure 2 shown and with reference to Figure 3 , the housing 300 is provided with a bottom plate 310 and a top plate 320 oppositely arranged along its height direction, the heat dissipation air duct 302 extends along the height direction of the housing 300, the first air inlet 303 and the first air outlet 304 are respectively arranged on the bottom plate 310 and the top plate 320 and communicated with the heat dissipation air duct 302, the first cooling fan 400 is correspondingly disposed at the first air outlet 304, and the electrolytic capacitor 222 of the capacitor board 220 is located on one side of the radiator 260. In this way, the air flow direction in the heat dissipation air duct 302 is parallel to the height direction of the housing 300, the convection effect reaches the maximum, and the internal hot air can be discharged smoothly, which is beneficial to further improving the heat dissipation effect.

[0058] Optionally, as Figure 2 shown, the top plate 320 may include a first sub-top plate 321 and a second sub-top plate 322 connected in a detachable manner. The first sub-top plate 321 faces the heat dissipation air duct 302, and the first air outlet 304 and the first cooling fan 400 are both disposed on the first sub-top plate 321. Thus, the convenience of disassembling the top plate 320 and the first cooling fan 400 can be improved.

[0059] In some embodiments, as Figure 1 , Figure 2 and Figure 5As shown in the figure, the elevator control cabinet 10 further includes a second bracket 500 disposed in the accommodation cavity 301. The second bracket 500 is located on the side of the drive board 210 away from the first bracket 100. The elevator control cabinet 10 further includes a control module and a power module. The drive module 200, the control module, and the power module are electrically connected to each other. The control module includes a control board 510, and the power module includes a power board 520. The control board 510 and the power board 520 are electrically connected and are both fixedly connected to the second bracket 500.

[0060] In this embodiment, the elevator control cabinet 10 further includes a control module and a power module. The control module includes a control board 510, and the power module includes a power board 520. The power module can draw power from the power connection terminal 250 of the drive board 210 and then convert it into power of various voltage levels to supply power to each component of the drive module 200 and the control module. The control module draws power from the power module through a wire harness; the control board 510 in the control module is the core of the control module. By controlling the drive module 200, it drives the elevator traction machine to work, thereby realizing control functions such as the elevator car ascending, descending, stopping and opening the door, and its shock absorption. Optionally, a control core board 511 is usually provided on the control board 510. The control core board 511 can be, for example, a microprocessor, a chip, etc.

[0061] Furthermore, in this embodiment, a second bracket 500 is further provided in the accommodation cavity 301 of the housing 300. The second bracket 500 is located on the side of the drive board 210 away from the first bracket 100. The control board 510 and the power board 520 are both fixedly connected to the second bracket 500. Thus, the control board 510, the power board 520, and the second bracket 500 are integrated into a modular whole. Such a setting can further improve the integration degree of the internal structure of the elevator control cabinet 10, and thus is beneficial to further realizing the miniaturization requirement of the elevator control cabinet 10. The above integrated structure can be applied to the elevator control cabinet 10 with a power of 45 kw to 55 kw. And, under the design of the above structure, the elevator control cabinet 10 of the present application is only about 45% of the volume of the elevator control cabinet 10 with the same power in the related art.

[0062] In some embodiments, as Figure 2 and Figure 5 shown, both the control board 510 and the power board 520 are located on the side of the second bracket 500 facing away from the drive board 210. The second bracket 500 is connected to the first bracket 100. The drive board 210 and the pre-charge board 230 are located between the first bracket 100 and the second bracket 500.

[0063] In this embodiment, the second bracket 500 is connected to the first bracket 100, thereby realizing the fixed installation of the second bracket 500 in the accommodation cavity 301. At the same time, the second bracket 500, the first bracket 100, and the components connected to the two together form a modular whole, which can further improve the integration degree inside the elevator control cabinet 10.

[0064] Furthermore, the drive board 210 and the pre-charge board 230 are located between the first bracket 100 and the second bracket 500, and the control board 510 and the power supply board 520 are both located on the side of the second bracket 500 away from the drive board 210. Such an arrangement enables a layered design of the elevator control cabinet 10 in the accommodation cavity 301. Specifically, in the accommodation cavity 301, along the direction from the first bracket 100 to the second bracket 500, the space on the side of the first bracket 100 away from the drive board 210 is the first layer, and this layer is the heat dissipation air duct 302 for dissipating heat from the radiator 260 and the capacitor board 220; the space between the first bracket 100 and the second bracket 500 is the second layer, and this layer is used to arrange structures such as the drive board 210, the pre-charge board 230, the lightning protection board 240, and the power supply terminal 250; the space on the side of the second bracket 500 away from the first bracket 100 is the third layer, and this layer is used to arrange structures such as the control module and the power supply module.

Furthermore, the volume of the elevator control cabinet 10 of the present application is about 45% of that of the control cabinet with the same power in the related art. In addition, by arranging the control module and the power supply module on the outermost side, the convenience of debugging and maintaining the elevator control cabinet 10 can also be improved.

[0065] In some embodiments, as Figure 5 shown and referring to Figure 2 , the power supply module further includes a second cooling fan 530. The second cooling fan 530 is fixedly connected to the second bracket 500, and the second cooling fan 530 is used to dissipate heat from the power supply board 520.

[0067] In some embodiments, Figure 2 and Figure 5 As shown, the elevator control cabinet 10 further includes a third bracket 700, which is connected to the second bracket 500 and is located on the side of the second bracket 500 away from the first bracket 100, and the human-machine interaction module 600 is arranged on the side surface of the third bracket 700 away from the second bracket 500. By setting the third bracket 700, the fixed installation of the human-machine interaction module 600 in the accommodating cavity 301 can be achieved. In addition, the third bracket 700 is located on the side of the second bracket 500 away from the first bracket 100, and the human-machine interaction module 600 is arranged on the side surface of the third bracket 700 away from the second bracket 500. That is, the human-machine interaction module 600 is located on the side farthest from the heat dissipation duct 302. Such a setting can further improve the convenience of personnel operation.

[0068] In some embodiments, Figure 2 and Figure 5 As shown, the control module also includes a UCMP board (not shown in the figure), which is arranged in the human-machine interaction module 600. The UCMP board refers to the elevator car accidental movement protection board (Unintended carmovement protection system), and the UCMP board is connected to the elevator car through a wiring harness to realize functions such as early door opening and door lock short circuit detection. The UCMP board can be electrically connected to the control board 510 by means of an external wiring harness. The UCMP board is arranged in the human-machine interaction module 600, so as to improve the convenience of maintenance and repair of the UCMP board.

[0069] Furthermore, if Figure 2 and Figure 5As shown, the housing 300 includes a front cover plate 330 located on the side of the third bracket 700 away from the second bracket 500. The front cover plate 330 is provided with an operation window 331 through which the human-machine interaction module 600 passes. Thus, the operator can operate the human-machine interaction module 600 without opening the front cover plate 330, which is convenient for debugging and maintenance. Further, a part of the human-machine interaction module 600 can extend into the operation window 331 and be flush with the outer surface of the front cover plate 330 to improve the structural regularity of the elevator control cabinet 10.

[0070] Optionally, as Figure 1 , Figure 2 and Figure 5 shown, the front cover plate 330 can be a split structure of upper and lower parts, and the upper and lower parts are connected in a detachable manner. Thus, the convenience of disassembling the front cover plate 330 can be improved, and further the convenience of debugging and maintaining the human-machine interaction module 600 can be improved.
