[0041] The elevator control cabinet 100 claimed in the present application, in particular, is applied to an elevator control cabinet with energy storage function in an elevator.

[0042] As shown in Figure 1 , Figure 2 The elevator control cabinet 100 provided by the present application includes a shell assembly 10, a capacitor assembly 20, a fan (not shown in the figure) and a converter 30 installed in the shell assembly 10. The capacitor assembly 20, the fan and the converter 30 are arranged from bottom to top in the shell assembly 10 along the height direction z of the elevator control cabinet 100. The bottom position of the shell assembly 10 is provided with an air inlet hole group 101, and the top position of the shell assembly 10 is provided with an air outlet hole group 102. The fan can guide the cold air introduced by the air inlet hole group 101 to pass through the capacitor assembly 20 and the converter 30 in turn and then be discharged from the air outlet hole group 102.

[0043] As can be seen from the above, the elevator control cabinet 100 of the present application uses the fan placed between the capacitor assembly 20 and the converter 30. When the elevator control cabinet 100 is working, the fan can first draw air from the capacitor assembly, so that the external cold air can enter the shell assembly 10 through the air inlet hole group 101 to cool the capacitor assembly 20. Then the fan guides the air passing through the capacitor assembly 20 to blow to the converter 30 to cool the converter 30. In this process, combined with the physical property that hot air goes up, the gas flow in the internal environment of the shell assembly is promoted, so that the elevator control cabinet 100 has the functions of simple structure and reducing equipment cost on the basis of meeting the effective heat dissipation of the capacitor assembly 20 and the converter 30, ensuring the rationality of the internal working environment temperature of the shell assembly 10 and prolonging the service life of the equipment.

[0044] It should be noted that when the elevator control cabinet 100 is working, the working environment temperature of the capacitor assembly 20 needs to be given priority to. The present application blows the coldest air introduced by the air inlet hole group 101 to the capacitor assembly 20 at first to meet the cooling demand of the capacitor assembly 20. Then the fan guides the air passing through the capacitor assembly 20 to blow to the converter 30 to realize the heat dissipation of the converter 30. In this process, since hot air itself goes up and the fan blows, the air flow in the internal environment of the elevator control cabinet 100 is promoted, and finally the hot air obtained after heat exchange is discharged from the air outlet hole group 102.

[0045] As shown in Figure 1 and Figure 3 In an embodiment, along the height direction z of the elevator control cabinet 100, the fan and the converter 30 are both installed within the projection range of the capacitor assembly 20. That is, the thickness and width of the fan and the converter 30 do not exceed the thickness and width of the capacitor assembly 20, so that the thickness and width of the elevator control cabinet 100 can be set according to the size of the capacitor assembly 20, thereby reducing the overall volume and achieving sufficient thinness and narrowness. At the same time, along the width direction x of the elevator control cabinet 100, the capacitor assembly 20, the fan and the converter 30 are installed at the middle position of the housing assembly 10, so that the housing assembly 10 has space on the left and right sides of the capacitor assembly 20, the fan and the converter 30 which can be used as wiring space, thereby facilitating the wiring of the elevator control cabinet 100.

[0046] As shown in Figures 1 to 3 In an embodiment, the housing assembly 10 includes a base 11, a cabinet housing 12 and a cover plate 13. The cabinet housing 12 can be connected and fixed to the base 11 by screws (not shown in the figure) to support the cabinet housing 12 by the base 11, and the cover plate 13 is covered on the cabinet housing 12, and specifically, the cover plate 13 covered on the cabinet housing 12 can be connected and fixed to the cabinet housing 12 by screws. In an embodiment, the top of the cabinet housing 12 is provided with a cover plate hanging buckle hole, and the cover plate 13 is provided with a hook boss, and the cover plate 13 is hung on the cabinet housing 12 by the cooperation of the hook boss and the cover plate hanging buckle hole to achieve covering; in this way, the assembly is convenient.

[0047] As shown in Figure 1 , Figure 3 In an embodiment, the air inlet hole group 101 includes a first air inlet hole group 1011, which is arranged at a lower position of the capacitor assembly 20 along the height direction z of the elevator control cabinet 100, and the air outlet hole group 102 is arranged at an upper position of the converter 30; and the first air inlet hole group 1011 and the air outlet hole group 102 are arranged on the side of the housing assembly 10 in the width direction x of the elevator control cabinet 100.

[0048] Specifically, the first air inlet hole group 1011 and the air outlet hole group 102 can each have one or more groups, and can be arranged on the same side or different sides. Here, the first air inlet hole group 1011 and the air outlet hole group 102 each have two groups, and the two groups of first air inlet hole groups 1011 and the two groups of air outlet hole groups 102 are arranged on the left and right side surfaces of the cabinet shell 12, so that the shell assembly 10 can introduce cold air from below the capacitor assembly 20 through the first air inlet hole groups 1011 on both sides to cool the capacitor assembly 20, and then blow the cold air to the current transformer 30, and then the air outlet hole groups 102 on both sides can guide the hot air from above the current transformer 30 to cool the current transformer 30. It should be noted that the specific number and arrangement position of the air inlet holes in the first air inlet hole group 1011 and the specific number and arrangement position of the air outlet holes in the air outlet hole group 102 can be specifically set according to the use requirements, which will not be described here.

[0049] As shown in Figure 1 , Figure 2 , in an embodiment, the air inlet hole group 101 further includes a second air inlet hole group 1012, which is arranged on the shell assembly 10 corresponding to the position of the capacitor assembly 20, and the second air inlet hole group 1012 is located on a different side of the shell assembly 10 from the first air inlet hole group 1011.

[0050] Corresponding to the position of the capacitor assembly 20, the second air inlet hole group 1012 is arranged on the different side of the first air inlet hole group 1011, which can make the external cold air flow through the capacitor assembly 20 from multiple directions, thereby improving the cooling efficiency of the capacitor assembly 20. The second air inlet hole group 1012 can be arranged in one or more groups, and when arranged in multiple groups, it can be arranged on the different sides of multiple shell assemblies 10 around the capacitor assembly 20. In this embodiment, the second air inlet hole group 1012 has two groups, one group of second air inlet hole groups 1012 is arranged on the side of the shell assembly 10 facing the capacitor assembly 20 along the thickness direction y of the elevator control cabinet 100, and the other group of second air inlet hole groups 1012 is arranged on the bottom surface of the shell assembly 10 below the capacitor assembly 20 along the height direction z of the elevator control cabinet 100. Here, the second air inlet hole group 1012 is arranged on the cover plate 13, so that the shell assembly 10 can introduce cold air from the front, left, right, and bottom of the capacitor assembly 20 through the first air inlet hole group 1011 and the second air inlet hole group 1012 to achieve efficient cooling of the capacitor assembly 20. It should be noted that the specific number and arrangement position of the air inlet holes in the second air inlet hole group 1012 can also be specifically set according to the use requirements, which will not be described here.

[0051] As can be seen from the above, the elevator control cabinet 100 of the present application can introduce cold air from different directions from the external environment to achieve cooling of the capacitor assembly 20, which can effectively cool the capacitor assembly 20.

[0052] As shown in Figure 1 , Figure 3 , in an embodiment, the capacitor assembly 20 comprises a super capacitor 21 and a capacitor bracket 22, the super capacitor 21 is fixedly installed in the cabinet shell 12 through the capacitor bracket 22.

[0053] As shown in Figure 1 , Figure 3 , in an embodiment, the converter 30 comprises a bidirectional converter control board 31; wherein the elevator control cabinet 100 further comprises a positive and negative copper bar 23, the positive and negative copper bar 23 is partially arranged on one side of the capacitor assembly 20 in the width direction x of the elevator control cabinet 100, and is respectively electrically connected with the capacitor assembly 20 and the bidirectional converter control board 31. Specifically, one end of the positive and negative copper bar 23 can be fixedly connected with the positive and negative poles of the super capacitor 21 in the capacitor assembly 20 by screws, and the other end of the positive and negative copper bar 23 is fixedly connected with the positive and negative poles of the bidirectional converter control board 31 by screws. Here, the fan can guide the wind to blow on the bidirectional converter control board 31 to cool it.

[0054] In this embodiment, the positive and negative copper bar 23 electrically connecting the capacitor assembly 20 and the bidirectional converter control board 31 of the elevator control cabinet 100 is arranged on one side of the capacitor assembly 20, which can shorten the wiring distance between the capacitor assembly 20 and the bidirectional converter control board 31, and save wiring space.

[0055] In an embodiment, as shown in Figure 1 , Figure 3 , the converter 30 further comprises an ARD converter 32 to meet the use requirements of the elevator control cabinet 100. Wherein, along the height direction z of the elevator control cabinet 100, the ARD converter 32 is arranged above the bidirectional converter control board 31. Since the heat generation of the ARD converter 32 is not as high as that of the bidirectional converter control board 31, the bidirectional converter control board 31 is made closer to the fan, so that the cooling efficiency is higher.

[0056] In an embodiment, as shown in Figure 1 , Figure 3As shown, along the height direction z of the elevator control cabinet 100, the bidirectional converter control board 31 is connected with a converter fan away from the side of the fan, the air inlet end of the converter fan is arranged to face the bidirectional converter control board 31, and the air outlet end of the converter fan is arranged to face the top surface of the shell assembly 10. Specifically, in this embodiment, the converter fan is connected to one end of the bidirectional converter control board 31 close to the ARD converter 32, and the air outlet end of the converter fan faces the ARD converter 32. Then the converter fan faces the bidirectional converter control board 31 to draw air and blows to the ARD converter 32. It can be understood that since the local components of the bidirectional converter control board 31 generate high heat, the converter fan can be added to the bidirectional converter control board 31 to solve the problem of local overheating of the bidirectional converter control board 31. Further improve the cooling efficiency inside the elevator control cabinet 100.

[0057] As shown in Figure 1 , Figure 3 In an embodiment, the air inlet end of the fan is arranged to face the capacitor assembly 20, and the air outlet end of the fan is arranged to face the converter 30; wherein the elevator control cabinet 100 further comprises a fan bracket 40 mounted in the shell assembly 10, specifically, the fan bracket 40 is fixedly connected in the cabinet shell 12 for carrying the fan. That is, the elevator control cabinet 100 of this embodiment can use the fan bracket 40 to carry the fan, so that the fan is assembled in the shell assembly 10 independently of the capacitor assembly 20 and the converter 30, which can facilitate the assembly and application of the fan in the elevator control cabinet 100. The number of fans is configured as one or more.

[0058] In an embodiment, the number of fans is configured as multiple, and the multiple fans are arranged in sequence along the width direction x of the elevator control cabinet 100, so that the elevator control cabinet 100 of this embodiment can use multiple fans to collectively dissipate heat from the capacitor assembly 20 and the converter 30, which can further improve the heat dissipation effect when dissipating heat from the capacitor assembly 20 and the converter 30. Here, the number of fans is configured as two. It can be understood that in other embodiments, the number of fans can also be three, four, or even more, which can be specifically set according to the use requirements, which will not be expanded here.

Along the height direction z of the elevator control cabinet 100, both the display panel assembly 51 and the terminal block assembly 52 are mounted within the projection range of the capacitor assembly 20. That is, the display panel assembly 51 and the terminal block assembly 52 do not exceed the width and thickness of the capacitor assembly 20 in either the width or thickness direction. Obviously, the arrangement of the display panel assembly 51 and the terminal block assembly 52 within the housing assembly 10 in this embodiment does not encroach on the space of the housing assembly 10 in the width direction x and the thickness direction y of the elevator control cabinet 100, and facilitates wiring, ensuring that the overall volume is sufficiently small.

[0060] Here, both the display panel assembly 51 and the terminal block assembly 52 are installed inside the cabinet housing 12. The display panel assembly 51 includes a display circuit board 511 and a display bracket 512. The display circuit board 511 can be fixed to the cabinet housing 12 via the display bracket 512. Specifically, an emergency stop button 513 is provided on the display circuit board 511. The cover plate 13 has an emergency stop sleeve mounting hole at the location of the emergency stop button 513, so that the operator can operate the emergency stop button 513 through the emergency stop sleeve mounting hole without opening the cover plate. It is understood that the emergency stop sleeve 131 is installed in the emergency stop sleeve mounting hole with an interference fit.

[0061] like Figure 1 As shown, in one embodiment, the elevator control cabinet 100 further includes an insulating plate 61 and multiple insulating plate supports 62. The multiple insulating plate supports 62 are disposed on both sides of the converter 30 in the width direction x of the elevator control cabinet 100, and are respectively connected to the housing assembly 10 and the insulating plate 61, so that the insulating plate 61 covers the converter 30, thereby insulating the converter 30 from the cover plate 13. Here, the number of insulating plate supports 62 is configured as two, and the two insulating plate supports 62 are installed on the cabinet housing 12. The insulating plate 61 abuts against the two insulating plate supports 62, specifically using screws to connect and fix the insulating plate 61 to the insulating plate supports 62.

[0062] In one embodiment, the elevator control cabinet 100 further includes positive and negative electrode insulating plates 80, which are installed inside the housing assembly 10 at positions corresponding to the positive and negative electrode copper busbars 23. Specifically, the positive and negative electrode insulating plates 80 are fixed to the inside of the cabinet housing 12 with screws, covering the area where the positive and negative electrode copper busbars 23 are located.

[0063] like Figure 3 , Figure 1 Figure 1 Figure 3As shown, in an embodiment, two handles 121 are installed on the left and right sides of the cabinet shell 12 in an interference fit manner at a position above the display panel assembly 51 and the terminal strip assembly 52 in the height direction z of the elevator control cabinet 100; the air outlet holes 102 formed on the left and right sides of the cabinet shell 12 are located at a position below the two handles 121 in the height direction z of the elevator control cabinet 100; and the perfluorocyclohexanone fire extinguisher 70 is installed and fixed on the top of the cabinet shell 12 above the two handles 121. In this way, the elevator control cabinet 100 is compact in the height direction while having perfect functions, further ensuring that the overall volume is reduced.

[0064] In summary, when the elevator control cabinet 100 is assembled, first, the cabinet shell 12 and the base 11 are connected and fixed together with screws, and then the two handles 121 are installed in the handle mounting holes on the left and right sides of the cabinet shell 12 in an interference fit manner; next, the emergency stop sleeve 131 is installed in the emergency stop sleeve mounting hole on the cover plate 13 in an interference fit manner, and then the two insulation plate supports 62 are installed and fixed in the cabinet shell 12 with screws.
