[0056] For the purpose of making the objects, technical solutions and advantages of the present application clearer, the following further describes the embodiments of the present application with reference to the accompanying drawings.

[0057] The following description refers to the accompanying drawings. Unless otherwise indicated, same or similar elements in different drawings are denoted by same or similar reference numerals. The embodiments described in the following exemplary embodiments are not representative of all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0058] Referring to Figures 1 to 3 The elevator control cabinet 10 provided by the embodiments of the present application comprises a drive module 1, a shell 4 and a first heat dissipation module 51. The shell 4 is formed with a receiving cavity 41, and the drive module 1 and the first heat dissipation module 51 are both located in the receiving cavity 41.

[0059] Referring to Figures 2 to 5 The drive module 1 comprises a male substrate 11, a drive component 12, a capacitor component 13 and a module component 14 integrated on the male substrate 11. The drive component 12, the capacitor component 13 and the module component 14 are electrically connected to each other. The module component 14 comprises a rectifier 141 and an inverter 142.

[0060] In the embodiments, the drive component 12, the capacitor component 13 and the module component 14 are integrated on the male substrate 11, which means that the drive component 12, the capacitor component 13 and the module component 14 are all arranged on the same substrate, i.e. the male substrate 11. Specifically, the circuit part of the drive component 12, the capacitor component 13 and the module component 14 can be formed on the surface of the male substrate 11 by etching or other processes, while the electronic device part of the drive component 12, the capacitor component 13 and the module component 14 can be mounted on the surface of the male substrate 11 by mechanical connection such as welding, clamping or screwing, and electrically connected to the circuit part on the male substrate 11. No limitation is made in this regard.

[0061] Compared with the drive module in the related art, which includes a drive board integrating the drive assembly, a capacitor board integrating the capacitor assembly, and the like, the drive module 1 has a higher integration degree, and the assembly process and wiring process between multiple circuit boards can be saved, thereby improving the assembly efficiency of the elevator control cabinet 10. The elevator control cabinet 10 according to the embodiment of the present application is suitable for a small-power elevator control cabinet 10, for example, a small-power elevator control cabinet 10 with a power greater than or equal to 5.5 kw and less than or equal to 7.5 kw. Through the combined design of the drive module 1, the overall volume of the elevator control cabinet 10 can be reduced.

[0062] It should be noted that the drive assembly 12, the capacitor assembly 13, and the module assembly 14 in the embodiment of the present application can be the drive assembly, the capacitor assembly, and the module assembly in the control cabinet in the related art, and only the carrier of the drive assembly 12, the capacitor assembly 13, and the module assembly 14 is different from that in the related art, without changes in the circuit.

[0063] For example, the input end of the rectifier 141 is connected to the alternating current power supply through the drive assembly 12, the output end of the rectifier 141 is connected to the input end of the inverter 142 through the capacitor assembly 13, the rectifier 141 is used to convert the alternating current power supply into direct current voltage, the capacitor assembly 13 can protect the entire circuit when the elevator control cabinet 10 starts, can reduce voltage fluctuations through discharging, and reduce harmonics. The output end of the inverter 142 is connected to the elevator hoisting machine through the drive assembly 12, the inverter 142 is used to convert the direct current voltage into alternating current voltage and output to the elevator hoisting machine, thereby driving the elevator car to run.

[0064] Further, the shell 4 has a bottom plate 42, and the public substrate 11 is opposite to and spaced apart from the bottom plate 42. Wherein, the extension direction of the public substrate 11 is substantially parallel to the extension direction of the bottom plate 42, and the two are substantially spaced apart in a direction perpendicular to the extension direction. That is, the plate surface of the public substrate 11 is substantially parallel to the plate surface of the bottom plate 42, so that the plate surface space of the bottom plate 42 can be fully utilized, and the space utilization rate in the shell 4 can be improved.

[0065] The first heat dissipation module 51 is arranged corresponding to the drive module 1, and the first heat dissipation module 51 is arranged between the bottom plate 42 and the public substrate 11 along the first direction x, the first direction x being a direction determined from the bottom plate 42 to the public substrate 11, and the first direction x can correspond to the thickness direction of the elevator control cabinet 10. Since the public substrate 11 of the drive module 1 integrates the drive assembly 12, the capacitor assembly 13, and the module assembly 14, the heat generating devices are relatively concentrated, and therefore the first heat dissipation module 51 is arranged corresponding to the drive module 1, so that the heat generated near the drive module 1 can be dissipated in a targeted manner, and the heat dissipation performance at the drive module 1 can be improved.

[0066] The first heat dissipation module 51 is arranged between the bottom plate 42 and the public substrate 11 in the first direction x, so that the first heat dissipation module 51 is arranged adjacent to the bottom plate 42, and the heat of the heat generating device absorbed by the first heat dissipation module 51 can be timely conducted outwards by the components of the shell 4 such as the bottom plate 42, the path of the heat conducted outwards by the first heat dissipation module 51 is shortened, and the heat dissipation efficiency is improved.

[0067] The first heat dissipation module 51 is arranged between the bottom plate 42 and the public substrate 11 in the first direction x, so that the first heat dissipation module 51 is arranged adjacent to the bottom plate 42, and the heat of the heat generating device absorbed by the first heat dissipation module 51 can be timely conducted outwards by the components of the shell 4 such as the bottom plate 42, the path of the heat conducted outwards by the first heat dissipation module 51 is shortened, and the heat dissipation efficiency is improved.

[0068] Further, the public substrate 11 has a first plate surface 111 facing the bottom plate 42, the rectifier 141 and the inverter 142 are arranged between the bottom plate 42 and the public substrate 11 in the first direction x, and the rectifier 141 and the inverter 142 are mounted on the first plate surface 111, and the first plate surface 111 is close to the first heat dissipation module 51, which is beneficial to shorten the distance between the rectifier 141 and the inverter 142 and the first heat dissipation module 51, and improve the heat dissipation speed near the rectifier 141 and the inverter 142.

[0069] The first heat dissipation module 51 can include a heat sink arranged corresponding to the rectifier 141 and the inverter 142 at the same time, so as to timely conduct out the heat generated by the rectifier 141 and the inverter 142. The first heat dissipation module 51 can also include a first heat sink 511 and a second heat sink 512, the first heat sink 511 is arranged corresponding to the rectifier 141, and is mainly used for dissipating heat of the rectifier 141; the second heat sink 512 is arranged corresponding to the inverter 142, and is mainly used for dissipating heat of the inverter 142.

[0070] The heat sink, the first heat sink 511 and the second heat sink 512 can be a heat pipe, a vapor chamber or the like, and are not limited in this regard.

[0071] Specifically, taking the heat sink as an example, the heat sink can have an evaporation end and a condensation end, and the heat sink is provided with a coolant, the evaporation end is arranged close to the rectifier 141 and the inverter 142 relative to the condensation end, when the elevator control cabinet 10 is working, the evaporation end is heated, the coolant can change from liquid phase to gas phase, and the gas phase of the coolant can change to liquid phase again after heat dissipation through the condensation end and flow back to the evaporation end. Wherein, after the coolant absorbs heat and vaporizes, it will carry heat, and the flow of the vaporized coolant is more flexible, so that it can reach the condensation end more quickly and make the heat dissipate outward, and thus circulate repeatedly, so that the heat sink can continuously dissipate heat outward. Wherein, the coolant can be fluorinated liquid, and the two-phase phase change heat transfer form of the fluorinated liquid makes the heat conduction efficiency higher, which is beneficial to improve the heat dissipation performance of the heat sink.

[0072] Further, the capacitor assembly 13 includes a capacitor 131, the capacitor 131 is arranged between the bottom plate 42 and the male substrate 11 along the first direction x, and the capacitor 131 is mounted on the first plate surface 111. By mounting the first heat dissipation module 51 and the capacitor 131 between the bottom plate 42 and the male substrate 11, the space utilization rate of the area between the bottom plate 42 and the male substrate 11 can be improved, and the size of the elevator control cabinet 10 in the first direction x can be reduced.

[0073] Wherein, the maximum size of the capacitor 131 in the first direction x can be substantially equal to the maximum size of the rectifier 141 and the first heat dissipation module 51 in the first direction x, and the maximum size of the capacitor 131 in the first direction x can be substantially equal to the maximum size of the inverter 142 and the first heat dissipation module 51 in the first direction x, so that the area between the bottom plate 42 and the male substrate 11 is slightly larger than the size of the capacitor 131 in the first direction x, which can meet the requirements of accommodating the capacitor 131, the rectifier 141, the inverter 142 and the first heat dissipation module 51, so that the area between the bottom plate 42 and the male substrate 11 in the first direction x is maximally utilized.

[0074] It should be noted that the rectifier 141 and the first heat dissipation module 51 can be arranged in close contact or spaced apart in the first direction x, therefore, the maximum size of the rectifier 141 and the first heat dissipation module 51 in the first direction x can be the distance between the farthest point of the rectifier 141 from the first heat dissipation module 51 in the first direction x and the farthest point of the first heat dissipation module 51 from the rectifier 141 in the first direction x. Similarly, the inverter 142 and the first heat dissipation module 51 can be arranged in close contact or spaced apart in the first direction x, therefore, the maximum size of the inverter 142 and the first heat dissipation module 51 in the first direction x can be the distance between the farthest point of the inverter 142 from the first heat dissipation module 51 in the first direction x and the farthest point of the first heat dissipation module 51 from the inverter 142 in the first direction x.

[0075] The common substrate 11 also has a second plate surface 112 opposite to the first plate surface 111, and the driving assembly 12 can be mounted on the second plate surface 112, that is, the driving assembly 12, the capacitor assembly 13 and the module assembly 14 are distributed on the second plate surface 112 and the first plate surface 111. Compared with arranging the driving assembly, the capacitor assembly and the module assembly on only one plate surface of the common substrate, the plate surface size of the common substrate 11 can be reduced, so that the common substrate 11 with a small plate surface can meet the device arrangement requirement, thereby reducing the size of the elevator control cabinet 10 in the second direction y and / or the third direction z. The first direction x, the second direction y and the third direction z are perpendicular to each other, the first direction x can correspond to the thickness direction of the elevator control cabinet 10, the second direction y can correspond to the length direction of the elevator control cabinet 10, and the third direction z can correspond to the width direction of the elevator control cabinet 10.

[0076] In addition, according to the layout of the driving module 1 in the shell 4, the size of the electronic devices in the driving assembly 12, the capacitor assembly 13 and the module assembly 14 in the first direction x, the embodiments of the present application design whether each electronic device is arranged on the first plate surface 111 or the second plate surface 112. For example, the capacitor 131 with a larger size in the first direction x is arranged on the first plate surface 111 to be arranged on the same side as the rectifier 141 and the inverter 142, so as to fully utilize the area reserved for arranging the first heat dissipation module 51 at the rectifier 141 and the inverter 142 in the shell 4; the driving assembly 12 and other electronic devices with smaller and substantially equal sizes in the first direction x are arranged on the second plate surface 112, so that the area reserved for the second plate surface 112 in the shell 4 can be fully utilized, the size of the driving module 1 in the first direction x is optimized, and the size of the elevator control cabinet 10 in the first direction x is reduced.

[0077] Further, referring to Figure 2 and Figure 6 The accommodating cavity 41 of the shell 4 includes a first cavity 411 and a second cavity 412, the first cavity 411 is arranged closer to the bottom plate 42 than the second cavity 412, the driving module 1 and the first heat dissipation module 51 are located in the first cavity 411, the plate surface of the bottom plate 42 includes a first area 421 and a second area 422, and the projection of the driving module 1 and the first heat dissipation module 51 on the plate surface of the bottom plate 42 is located in the first area 421. That is, the driving module 1 and the first heat dissipation module 51 occupy part of the space of the first cavity 411 at the bottom of the accommodating cavity 41, and the first cavity 411 still has part of the space for mounting other modules.

[0078] In the embodiment of the present application, the elevator control cabinet 10 further comprises a power module 3, the power module 3 is electrically connected with the drive module 1, the power module 3 comprises a power board 31, the power board 31 is located in the first chamber 411, and the projection of the power board 31 on the plate surface of the bottom plate 42 is located in the second area 422. That is, the remaining space in the first chamber 411 except the drive module 1 and the first heat dissipation module 51 can be used to install the power board 31, so that the power board 31, the drive module 1 and the first heat dissipation module 51 are arranged in the first chamber 411 in a partitioned manner, and the space utilization of the first chamber 411 is improved.

[0079] Since the maximum size of the power board 31 in the first direction x is close to the maximum size of the drive module 1 in the first direction x, for example, the maximum size of the power board 31 in the first direction x is m1, the maximum size of the drive module 1 in the first direction x is m2, and 0.7≤m1 / m2≤1. Therefore, arranging the power board 31 and the drive module 1 in the first chamber 411 can make the size of the first chamber 411 in the first direction x slightly larger than the maximum size of the drive module 1 in the first direction x, that is, the requirement of accommodating the power board 31 and the drive module 1 can be met, so that the area of the first chamber 411 in the first direction x is maximally utilized.

[0080] In combination with the above description, the first heat dissipation module 51, the rectifier 141, the inverter 142 and the capacitor 131 are located on the side of the first plate surface 111 of the common base plate 11, and the maximum size of the capacitor 131 in the first direction x is substantially equal to the maximum size of the rectifier 141 and the first heat dissipation module 51 in the first direction x, and the maximum size of the capacitor 131 in the first direction x is substantially equal to the maximum size of the inverter 142 and the first heat dissipation module 51 in the first direction x. Therefore, after the size of the first chamber 411 is determined according to the drive module 1, the first chamber 411 also meets the requirement of accommodating the first heat dissipation module 51.

[0081] Since the first plate surface 111 and the second plate surface 112 of the common base plate 11 are both provided with electronic devices, the maximum size of the drive module 1 in the first direction x refers to the distance between the point farthest from the first plate surface 111 of the electronic device on the first plate surface 111 in the first direction x and the point farthest from the second plate surface 112 of the electronic device on the second plate surface 112 in the first direction x.

[0082] Similarly, if the electronic devices are arranged on both of the opposite board surfaces of the power board 31, the maximum dimension of the power board 31 in the first direction x refers to the distance between the point farthest from one of the board surfaces of the electronic devices on the one of the board surfaces of the power board 31 in the first direction x and the point farthest from the other of the board surfaces of the electronic devices on the other of the board surfaces of the power board 31 in the first direction x. If only one of the opposite board surfaces of the power board 31 is arranged with the electronic devices, the maximum dimension of the power board 31 in the first direction x refers to the distance between the point farthest from the one of the board surfaces of the electronic devices on the one of the board surfaces of the power board 31 in the first direction x and the other of the board surfaces of the power board 31. In the embodiment of the present application, only one of the opposite board surfaces of the power board 31 is arranged with the electronic devices, and the other of the board surfaces is used for mounting and fixing the power board 31 in the shell 4, which will be described in detail below.

[0083] In the embodiment of the present application, the value of m1 / m2 can be 0.70, 0.75, 0.85, 0.9, 0.95, 1, etc., which can be flexibly designed in combination with actual needs. The value of m1 can be 48 mm, 55 mm, 60 mm, 65 mm, 70 mm, etc., and the value of m2 can be 68 mm, 74 mm, 80 mm, 83 mm, 85 mm, etc., which can be flexibly designed in combination with actual needs.

[0084] The elevator control cabinet 10 further comprises a control module 2, which is electrically connected with the drive module 1 and the power module 3. The control module 2 comprises a UCMP (Unintended car movement protection system) board 22, which is located in the first chamber 411. At least part of the projection of the UCMP board 22 on the bottom plate 42 coincides with the projection of the power board 31 on the bottom plate 42. The maximum dimension of the UCMP board 22 and the power board 31 in the first direction x is m3, and the maximum dimension of the drive module 1 in the first direction x is m2, wherein 0.85≤m3 / m2≤1. By arranging the UCMP board 22 in the interval reserved at the power board 31 in the first chamber 411, the space utilization of the first chamber 411 can be further improved.

[0085] In the embodiment of the present application, the value of m3 / m2 can be 0.9, 0.92, 0.95, 0.97, 1, etc., which can be flexibly designed in combination with actual needs. The value of m3 can be 66 mm, 73 mm, 78 mm, 82 mm, 84 mm, etc., and the value of m2 can be 68 mm, 74 mm, 80 mm, 83 mm, 85 mm, etc., which can be flexibly designed in combination with actual needs.

[0086] The maximum dimension of the UCMP board 22 and the power board 31 in the first direction x refers to the distance between the point on the UCMP board 22 furthest from the power board 31 and the point on the power board 31 furthest from the UCMP board 22.

[0087] Furthermore, the electronic components on the UCMP board 22 can be located on the side of the UCMP board 22 closer to the power board 31, and the electronic components on the power board 31 can be located on the side of the power board 31 closer to the UCMP board 22. In this case, the maximum dimension of the UCMP board 22 and the power board 31 in the first direction x refers to the distance between the surface of the UCMP board 22 facing away from the power board 31 and the surface of the power board 31 facing away from the UCMP board 22.

[0088] The UCMP board 22 can roughly correspond to the smaller electronic components on the power board 31 in the first x direction. Since the board size of the UCMP board 22 is relatively smaller than that of the power board 31, the arrangement of the UCMP board 22 in the first chamber 411 is more flexible. By arranging it to correspond to the smaller electronic components on the power board 31 in the first x direction, the UCMP board 22 can be accommodated even with the limited size of the first chamber 411 in the first x direction, making the arrangement of components in the elevator control cabinet 10 more compact.

[0089] In the embodiments of this application, such as Figure 2 As shown, the electronic components in the upper left corner of the power board 31 are relatively small. The UCMP board 22 can be set in the upper left corner of the power board 31. The size of the first chamber 411 in the first direction x only needs to be slightly larger than the maximum size of the drive module 1 in the first direction x.

[0090] Furthermore, the projection of the UCMP board 22 onto the surface of the base plate 42 can be entirely located in the second region 422, or partially located in the second region 422 and partially located in the first region 421, which can be flexibly adjusted according to the actual situation.

[0091] The first region 421 and the second region 422 can be arranged along the second direction y. The maximum dimension of the power board 31 in the second direction y is n1, and the maximum dimension of the drive module 1 in the second direction y is n2, where 0.8 ≤ n1 / n2 ≤ 1. That is, the maximum dimension of the power board 31 in the second direction y is close to the maximum dimension of the drive module 1 in the second direction y, and the two can roughly evenly divide the plate area of ​​the base plate 42, so that the distribution of the components in the second direction y within the first chamber 411 is roughly balanced, and the weight distribution of the elevator control cabinet 10 is relatively balanced. The maximum dimension of the power board 31 in the second direction y can be the maximum dimension of the base plate 31 in the second direction y, and the maximum dimension of the drive module 1 in the second direction y can be the maximum dimension of the base plate 11 in the second direction y, without limitation.

[0092] In the embodiments of the present application, the value of n1 / n2 can be 0.8, 0.85, 0.90, 0.95, 1, etc., which can be flexibly designed in combination with actual needs. The value of n1 can be 135 mm, 145 mm, 156 mm, 160 mm, 175 mm, etc., and the value of n2 can be 130 mm, 142 mm, 153 mm, 158 mm, 169 mm, etc., which can be flexibly designed in combination with actual needs.

[0093] Further, the elevator control cabinet 10 further comprises a first mounting bracket 61, the first mounting bracket 61 is located in the accommodating cavity 41, the first mounting bracket 61 is mounted to the shell 4, and the driving module 1, the first heat dissipation module 51 and the power board 31 are all mounted to the first mounting bracket 61. That is, the driving module 1, the first heat dissipation module 51 and the power board 31 can be mounted to the elevator control cabinet 10 through the first mounting bracket 61, so that when assembling the elevator control cabinet 10, the driving module 1, the first heat dissipation module 51, the power board 31 and the first mounting bracket 61 can be assembled outside the shell 4 first, and then they are installed in the shell 4 together. Compared with installing the driving module, the first heat dissipation module and the power board separately in the shell with limited space, the assembly is more convenient, and when performing maintenance and replacement, the driving module 1, the first heat dissipation module 51, the power board 31 and the first mounting bracket 61 can be removed from the shell 4 together, which is also more convenient for disassembly and facilitates maintenance work.

[0094] Specifically, referring to Figures 2 to 5 , the first mounting bracket 61 can include a first plate 611, a second plate 612 and a third plate 613.

[0095] The first plate 611 is provided corresponding to the driving module 1, and the first plate 611 can be arranged between the first heat dissipation module 51 and the male base plate 11 along the first direction x. The male base plate 11 is mounted on the first plate 611, and the first plate 611 is formed with a first through hole 6111 corresponding to the rectifier 141, a second through hole 6112 corresponding to the inverter 142 and a third through hole 6113 corresponding to the capacitor 131. The first heat dissipation module 51 can be mounted on the first plate 611 or the male base plate 11. In the embodiments of the present application, the first heat dissipation module 51 is mounted on the first plate 611, and the first heat dissipation module 51 and the male base plate 11 are both mounted on the first plate 611, so that the alignment of the first heat dissipation module 51 and the male base plate 11 can be realized outside the shell 4, which is more convenient for assembly and alignment compared with mounting the first heat dissipation module and the male base plate on different carriers.

[0096] The second plate 612 is arranged between the power supply plate 31 and the bottom plate 42 along the first direction x, and the power supply plate 31 is arranged on the second plate 612. The second plate 612 is arranged at intervals with the first plate 611 along the first direction x, and the third plate 613 is connected to the first plate 611 and the second plate 612. The first plate 611 and the second plate 612 are arranged at intervals, which is beneficial to distinguish the first plate 611 and the second plate 612, and further beneficial to distinguish the installation positions of the drive module 1, the first heat dissipation module 51 and the power supply plate 31, and reduce the installation difficulty.

[0097] The installation mode between the first plate 611 and the public base plate 11, between the first plate 611 and the first heat dissipation module 51, and between the second plate 612 and the power supply plate 31 can be any mode.

[0098] In the embodiment, the first plate 611 is installed on the public base plate 11 by a rivet process. For example, one of the first plate 611 and the public base plate 11 is provided with a rivet nut, and the other is provided with a first mounting hole. A rivet screw can be installed in the corresponding rivet nut through the first mounting hole, so as to complete the installation of the first plate 611 and the public base plate 11. For another example, one of the first plate 611 and the public base plate 11 is provided with a rivet screw, and the other is provided with a second mounting hole. The rivet screw can be connected with the rivet nut through the corresponding second mounting hole, so as to install the first plate 611 and the public base plate 11. In the embodiment, the second plate 612 is installed on the power supply plate 31 by a rivet process, which is similar to the above-mentioned installation of the first plate 611 on the public base plate 11 by a rivet process, and will not be described herein. In the embodiment, the first plate 611 is installed on the first heat dissipation module 51 by a screw or other locking member.

[0099] Further, the first plate 611 and the public base plate 11 are arranged at intervals along the first direction x, and the second plate 612 and the power supply plate 31 are arranged at intervals along the first direction x, so that the first plate 611 and the public base plate 11 and the second plate 612 and the power supply plate 31 have an insulating gap.

[0100] The interval between the first plate 611 and the public base plate 11 along the first direction x is greater than or equal to 7 mm and less than or equal to 12 mm, which ensures that the first plate 611 and the public base plate 11 have sufficient insulating gap and meet the miniaturization design of the elevator control cabinet 10. Specifically, the interval between the first plate 611 and the public base plate 11 along the first direction x can be 7 mm, 8 mm, 8.5 mm, 9 mm, 10 mm, 12 mm, etc.

[0101] The distance between the second plate 612 and the power panel 31 in the first direction x is greater than or equal to 7 mm and less than or equal to 12 mm, which ensures that there is sufficient insulation gap between the second plate 612 and the power panel 31, and at the same time, the miniaturization design of the elevator control cabinet 10 is met. Specifically, the distance between the second plate 612 and the power panel 31 in the first direction x can be 7 mm, 8 mm, 8.5 mm, 9 mm, 10 mm, 12 mm, etc.

[0102] The plate surface of the power panel 31 where no electronic device is arranged can be arranged to face the second plate 612, thereby reducing the obstruction when the power panel 31 is connected to the second plate 612.

[0103] Further, the third plate 613 is located between the first plate 611 and the second plate 612 along the second direction y. The third plate 613 is arranged at an angle with respect to the first plate 611 and the second plate 612. The third plate 613 and the first plate 611 define a first heat dissipation channel 614, and the third plate 613 and the second plate 612 define a second heat dissipation channel 615.

[0104] The elevator control cabinet 10 further comprises a first heat dissipation fan 52 and a second heat dissipation fan 53. The housing 4 is formed with a first air inlet 431 and a first air outlet 432 which communicate with the first heat dissipation channel 614. The first heat dissipation fan 52 is arranged corresponding to the first air outlet 432. The housing 4 is formed with a second air inlet 433 and a second air outlet 434 which communicate with the second heat dissipation channel 615. The second heat dissipation fan 53 is arranged corresponding to the second air outlet 434. The layout of the first plate 611, the second plate 612 and the third plate 613 of the first mounting bracket 61 is optimized, so that the first heat dissipation channel 614 and the second heat dissipation channel 615 are relatively independent.

[0105] Further, the first mounting bracket 61 further comprises a fourth plate 616 and a fifth plate 617.

[0106] The fourth plate 616 and the third plate 613 are located on the same side of the first plate 611 along the first direction x. The fourth plate 616 and the third plate 613 are located on opposite sides of the first plate 611 along the second direction y. One end of the fourth plate 616 is connected to the first plate 611, and the other end extends towards the bottom plate 42. The fourth plate 616, the first plate 611 and the third plate 613 form the first heat dissipation channel 614. The fifth plate 617 and the third plate 613 are located on the same side of the second plate 612 along the first direction x. The fifth plate 617 and the third plate 613 are located on opposite sides of the second plate 612 along the second direction y. One end of the fifth plate 617 is connected to the second plate 612, and the other end extends away from the bottom plate 42. The fifth plate 617, the second plate 612 and the third plate 613 form the second heat dissipation channel 615, so that the first heat dissipation channel 614 and the second heat dissipation channel 615 are more independent.

[0107] And the first heat dissipation channel 614 and the second heat dissipation channel 615 are independent, which is conducive to the reasonable design of the first heat dissipation fan 52 and the second heat dissipation fan 53 according to the heat dissipation demand in the first heat dissipation channel 614 and the heat dissipation demand in the second heat dissipation channel 615. For example, when the elevator control cabinet 10 is working, the heat generated in the first heat dissipation channel 614 is relatively high, and the heat generated in the second heat dissipation channel 615 is relatively low. The first heat dissipation fan 52 can be designed to select a high-power fan, the second heat dissipation fan 53 can be designed to select a low-power fan, or the first heat dissipation fan 52 can include more heat dissipation fans than the second heat dissipation fan 53, and so on.

[0108] It should be noted that since the first heat dissipation module 51 is also located in the first heat dissipation channel 614, the first heat dissipation fan 52 can also take away the heat absorbed by the first heat dissipation module 51 through external airflow, thereby improving the heat dissipation speed in the first heat dissipation channel 4121.

[0109] Specifically, the first air outlet 432 and the first air inlet 431 are located on opposite sides of the first heat dissipation module 51 along the third direction z.

[0110] Further, the first heat dissipation module 51 can form at least one heat dissipation flow channel, and the two ends of the heat dissipation flow channel are respectively arranged corresponding to the first air inlet 431 and the first air outlet 432, so as to improve the heat dissipation area of the first heat dissipation module 51 and improve the heat dissipation performance. The first heat dissipation module 51 can include multiple heat dissipation fins, and the heat dissipation flow channel can be formed between adjacent two heat dissipation fins, which is not limited. The chambers for the flow of the cooler can be formed in each heat dissipation fin, and the chambers in each heat dissipation fin can be connected or independent, which is not limited.

[0111] Specifically, the second air inlet 433 and the first air inlet 431 can be located on the same side of the shell 4, and the second air outlet 434 and the first air outlet 432 can be located on the same side of the shell 4.

[0112] Further, the elevator control cabinet 10 further comprises a partition plate 62, the partition plate 62 is located in the accommodating cavity 41, the partition plate 62 is installed on the shell 4, and the partition plate 62 divides the accommodating cavity 41 into a first cavity 411 and a second cavity 412. The control module 2 comprises a control board 21 and a UCMP board 22, the control board 21 is located in the second cavity 412 and is installed on the partition plate 62, and the UCMP board 22 is located in the first cavity 411 and is installed on the partition plate 62. That is, the control board 21 and the UCMP board 22 can be installed on the elevator control cabinet 10 through the partition plate 62. Therefore, when assembling the elevator control cabinet 10, the control board 21 and the UCMP board 22 can be assembled with the partition plate 62 outside the shell 4 first, and then installed in the shell 4 together. Compared with installing the control board and the UCMP board in the shell with limited space respectively, the assembly is more convenient, and when performing maintenance and replacement, the control board 21 and the UCMP board 22 can be removed from the shell 4 together with the partition plate 62, which is also more convenient for disassembly and facilitates maintenance work.

[0113] In addition, the control board 21 and the UCMP board 22 are arranged on opposite sides of the partition plate 62 respectively, so that the assembly of the control board 21, the UCMP board 22 and the partition plate 62 does not affect each other, which is beneficial to the smooth assembly. Further, the electronic devices on the control board 21 are arranged on the side of the control board 21 away from the partition plate 62, and the electronic devices on the UCMP board 22 are arranged on the side of the UCMP board 22 away from the partition plate 62, so that the assembly of the control board 21 and the partition plate 62 and the assembly of the UCMP board 22 and the partition plate 62 are more convenient.

[0114] It should be noted that the control board 21, the UCMP board 22 and the power supply board 31 in the embodiments of the present application can be control boards, UCMP boards and power supply boards in related technologies, and only the arrangement position in the shell 4 is changed without changes in the circuit compared with related technologies.

[0115] For example, the power supply module 3 is used to take power from the drive assembly 12 of the drive module 1, and then convert it into power supply of various voltage levels to power various electrical devices. The control module 2 takes power from the power supply module 3 through a wire harness; the control board 21 in the control module 2 is the core of the control module 2, which controls the drive module 1 to drive the elevator traction machine to work, thereby realizing the control functions of elevator car ascending, descending, stopping, opening door and shock absorption; the UCMP board 22 in the control module 2 is connected with the elevator car through a wire harness to realize the functions of opening door in advance and detecting door lock short circuit; the control board 21 and the UCMP board 22 in the control module 2 are connected through a wire harness.

[0117] It should be noted that the human-computer interaction module 7 in the embodiments of the present application can be a human-computer interaction module in the related art, and only the change in the setting position in the shell 4 is changed without the change in the circuit relative to the related art.

[0118] For example, the human-computer interaction module 7 includes an emergency stop button, a change-over switch, and a button board card. The human-computer interaction module 7 takes power from the power module 3 through a wire harness. The emergency stop button in the human-computer interaction module 7 is connected to the elevator safety circuit through a wire harness to realize the shutdown of the elevator in an emergency state. The change-over switch in the human-computer interaction module 7 is connected to the elevator safety circuit through a wire harness to realize the conversion of different working states of the elevator. The button board card in the human-computer interaction module 7 is connected to the control board 21 in the control module 2 through a wire harness to realize the execution of the human-computer interaction instruction.

[0119] The shell 4 further includes a cover plate 44 opposite to the bottom plate 42 and a side plate 45 connected to the bottom plate 42 near the side of the cover plate 44. The cover plate 44 and the side plate 45 are movably connected. The human-computer interaction module 7 is arranged adjacent to the cover plate 44. The cover plate 44 is designed to be movably connected to the side plate 45, so that the operator can operate the human-computer interaction module 7 by changing the position of the cover plate 44 relative to the side plate 45. The movably connection between the cover plate 44 and the side plate 45 can be rotatable connection, movable connection, etc., which is not limited.

[0120] An operation window 441 can be formed on the cover plate 44. The human-computer interaction module 7 can be arranged corresponding to the operation window 441, so that the operator can operate the human-computer interaction module 7 without opening the cover plate 44, which is convenient for debugging and maintenance. Further, part of the human-computer interaction module 7 can be inserted into the operation window 441 and flush with the outer surface of the cover plate 44 to improve the structural regularity of the elevator control cabinet 10.

[0121] The human-computer interaction module 7 is located in the second chamber 412. The human-computer interaction module 7 is installed on the control board 21, so that the human-computer interaction module 7 can also be assembled on the partition plate 62 and the control board 21 outside the shell 4, and then installed in the shell 4 together, which is convenient for disassembly and assembly.

[0122] Further, the elevator control cabinet 10 further includes two second mounting brackets 63 and a cover plate 64.

[0123] Two second mounting supports 63 are located in the second chamber 412, the two second mounting supports 63 are located on the side of the control panel 21 away from the bottom plate 42, the two second mounting supports 63 are located on the opposite sides of the human-computer interaction module 7 in the second direction y, and the two second mounting supports 63 are both mounted on the human-computer interaction module 7. A cover plate 64 is connected between the two second mounting supports 63, the cover plate 64 covers the control panel 21, the control panel 21 is provided with interface terminals, and the cover plate 64 is formed with windows corresponding to the interface terminals. In this way, during the assembly of the elevator control cabinet 10, the UCMP panel 22 and the control panel 21 can be first mounted on the partition plate 62 outside the shell 4, then the human-computer interaction module 7 is mounted on the control panel 21, and then the two second mounting supports 63 are mounted on the human-computer interaction module 7 and the cover plate 64 is mounted on the two second mounting supports 63, and finally they are mounted in the shell 4, which is convenient to disassemble and assemble.

In the embodiment of the present application, the circuit breaker 8 is arranged in the elevator control cabinet 10, compared with the related art in which the circuit breaker is arranged outside the control cabinet, the wiring between the circuit breaker 8 and the electronic devices in the drive module 1 in the elevator control cabinet 10 can be completed before the elevator control cabinet 10 is sold, which reduces the wiring burden of the operator and improves the product competitiveness of the elevator control cabinet 10. Specifically, the drive module 1 can be connected with alternating current mains through the circuit breaker 8, for example, connected with alternating current mains through the R interface, the S interface, the T interface and the N interface on the circuit breaker 8. The circuit breaker 8 in the embodiment of the present application can be a circuit breaker connected with the control cabinet in the related art, and compared with the related art, only the arrangement position of the circuit breaker 8 is changed without changing the circuit.

[0125] Further, the circuit breaker 8 is located in the first chamber 411, and the projection of the circuit breaker 8 on the bottom plate 42 is located in the third region 423 outside the first region 421 and the second region 422, so as to further improve the space utilization of the first chamber 411.

[0126] Among them, the third region 423 can be located on one side of the first region 421 close to the second region 422, that is, the third region 423 is arranged approximately in the middle, and then the circuit breaker 8 is arranged approximately in the middle, so as to design a wiring window corresponding to the circuit breaker 8 approximately in the middle of the shell 4.

[0127] At least part of the third area 423 is embedded in the first area 421. Since the area occupied by the circuit breaker 8 is relatively small, the third area 423 can be relatively small. Embedding the third area 423 in the first area 421 can improve the design size of the first area 421, and further improve the size of the male base plate 11 arranged corresponding to the first area 421, and improve the space utilization of the first chamber 411. For example, the first area 421 can be designed in an L shape, and the male base plate 11 arranged corresponding to the first area 421 can also be designed in an L shape.

[0128] The circuit breaker 8 is mounted on the first mounting bracket 61, so that the circuit breaker 8 can be mounted in the accommodating cavity 41 of the shell 4 together with the drive module 1 and the power panel 31 after being mounted on the first mounting bracket 61, which is convenient for disassembly and assembly.

The sixth plate 618 and the seventh plate 619 are arranged at an angle and form a mounting cavity for mounting the circuit breaker 8, which improves the connection stability between the circuit breaker 8 and the first mounting bracket 61.

[0130] The sixth plate 618 can be perpendicular to the seventh plate 619, and the sixth plate 618 can be perpendicular to the first plate 611, which is not limited.
