In addition, the fan assembly is connected with the main body frame in a detachable manner, and the top plate of the cabinet body is provided with a wiring terminal. Therefore, the lead wire of the fan assembly can be connected to the wiring terminal, so as to establish an electrical connection relationship with the electrical control panel in the cabinet body. When the fan assembly needs to be disassembled, the fan assembly is disassembled from the main body frame, and the connection between the lead wire and the wiring terminal is disconnected. Conversely, when the fan assembly needs to be installed, the lead wire can be connected to the wiring terminal first, and then the fan assembly is connected with the main body frame. The wiring terminal is provided, so that the connection and disconnection of the lead wire can be operated outside the cabinet body, thereby the fan assembly can be easily disassembled and installed, which brings convenience to the maintenance and replacement of the fan assembly.

[0006] In some embodiments, the fan assembly comprises a fixing plate, which is detachably connected with the main frame; a first fan, which is mounted on the fixing plate, the first fan being located on the side of the fixing plate close to the top plate, the fixing plate being provided with a ventilation hole opposite to the first fan, and the wire being connected with the first fan.

[0007] The fixing plate can provide a mounting base for the first fan, and facilitate the connection between the fan assembly and the main frame. In addition, the first fan is mounted on the side of the fixing plate close to the top plate, so that the first fan is not exposed outside the elevator control cabinet, thereby the fixing plate has a certain protective effect on the first fan. The fixing plate is provided with a ventilation hole, and the ventilation hole is arranged opposite to the first fan. Thus, when the first fan is working, external airflow can pass through the fixing plate through the ventilation hole, and then enter the inside of the box through the first ventilation hole under the driving action of the first fan, thereby cooling and heat dissipation for the electronic devices inside the box.

[0008] In some embodiments, the fan assembly further comprises a protective net, which is connected with the fixing plate and covers the ventilation hole.

In this way, the top plate and the main frame can protect the fan assembly, preventing external objects from touching the fan assembly and causing damage or abnormal operation of the fan assembly. In addition, the fan assembly can be designed in a concealed manner, so that the fan assembly is not exposed, which is also conducive to keeping the appearance of the elevator control cabinet simple, thereby improving the overall aesthetic appearance of the elevator control cabinet.

[0012] In some embodiments, the first ventilation opening is provided with a ventilation grille. By providing the ventilation grille at the first ventilation opening, the airflow can enter the interior of the cabinet through the first ventilation opening while preventing external objects from falling into the cabinet through the first ventilation opening.

[0013] In some embodiments, the main frame comprises a back plate, a first side plate and a second side plate connected to the back plate; the elevator control cabinet further comprises: a mounting plate arranged in the interior of the cabinet, the mounting plate being connected to the first side plate and the second side plate; a board card provided with power devices, the board card being arranged on the mounting plate; and a second fan arranged on the first side plate, the first side plate being provided with a second ventilation opening, the second side plate being provided with a third ventilation opening, the second fan being opposite to the second ventilation opening, and the second fan being used for cooling the board card.

[0014] The second fan is arranged on the first side plate, the first side plate is provided with the second ventilation opening, the second side plate is provided with the third ventilation opening, one of the second ventilation opening and the third ventilation opening can be used as an air inlet, and the other can be used as an air outlet.

[0016] The board card and the power element assembly are arranged on different sides of the mounting plate, which is conducive to avoiding the heat generated by the board card and the heat generated by the power element assembly from being concentrated together. In addition, the second fan and the board card are arranged on the same side of the mounting plate, and the first ventilation opening and the power element assembly are arranged on the same side of the mounting plate, so that the second fan can cool the board card, and the fan assembly can cool the power element assembly, which is conducive to improving the heat dissipation efficiency of the elevator control cabinet.

[0017] In some embodiments, the elevator control cabinet further comprises a baffle plate, the baffle plate and the board card are arranged on the same side of the mounting plate, the baffle plate is connected to the mounting plate, the baffle plate and the mounting plate jointly define a heat dissipation air duct, the board card is arranged in the heat dissipation air duct, and the second ventilation opening and the third ventilation opening are arranged at two ends of the heat dissipation air duct.

[0018] By setting up a baffle plate and using the baffle plate and mounting plate to form a heat dissipation air duct, and with the circuit board located inside the heat dissipation air duct, the airflow provided by the second fan can pass through the circuit board in a more concentrated manner, thereby dissipating heat from the circuit board more effectively.

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

[0036] like Figures 1 to 6 As shown in the figure, this application embodiment provides an elevator control cabinet 10, which includes a housing 100, a fan assembly 200, and a terminal block 300. The housing 100 includes a main frame 101 and a top plate 102, with the top plate 102 connected to the top of the main frame 101. The fan assembly 200 is disposed on the top of the housing 100 and is detachably connected to the main frame 101. The top plate 102 has a first ventilation opening 1021, which is opposite to the fan assembly 200. The terminal block 300 passes through the top plate 102, and the fan assembly 200 has wires (not shown in the figure). The terminal block 300 is used to connect the wires.

[0037] Specifically, the cabinet 100 is a housing part of the elevator control cabinet 10, and is used to protect the internal structure of the elevator control cabinet 10. The cabinet 100 comprises a main frame 101 and a top plate 102, wherein the main frame 101 comprises a back plate 1011, a first side plate 1012 and a second side plate 1013 connected with the back plate 1011, and the main frame 101 can be made by sheet metal processing. In addition, the cabinet 100 usually comprises a bottom plate 103 connected with the bottom of the main frame 101 and a cabinet panel 104 connected with the front of the main frame 101, so that the cabinet panel 104 is opposite to the back plate 1011. The cabinet panel 104 can be connected with the main frame 101 by a hinge on one side, so that the cabinet panel 104 is functionally similar to a door body, and the cabinet panel 104 can be opened in a rotating manner to expose the internal structure of the elevator control cabinet 10, or the cabinet panel 104 can be connected with the main frame 101 by a screw connection, so that the cabinet panel 104 can be disassembled by disassembling the screw to expose the internal structure of the elevator control cabinet 10.

[0038] In the embodiment, the fan assembly 200 of the elevator control cabinet 10 is arranged on the top of the cabinet 100, the top plate 102 of the cabinet 100 is provided with a first ventilation opening 1021 opposite to the fan assembly 200, so that the fan assembly 200 can drive air flow when working, and the air flow enters the inside of the cabinet 100 through the first ventilation opening 1021 to cool and heat dissipate the electronic devices in the cabinet 100. In addition, the fan assembly 200 is detachably connected with the main frame 101, and the top plate 102 of the cabinet 100 is provided with a wiring terminal 300, so that the lead wire of the fan assembly 200 can be connected with the wiring terminal 300 to establish an electrical connection relationship with the control panel in the cabinet 100. When the fan assembly 200 needs to be disassembled, the fan assembly 200 is disassembled from the main frame 101, and the connection between the lead wire and the wiring terminal 300 is disconnected. Conversely, when the fan assembly 200 needs to be installed, the lead wire can be connected with the wiring terminal 300 first, and then the fan assembly 200 is connected with the main frame 101. The wiring terminal 300 is arranged, so that the connection and disconnection of the lead wire can be operated outside the cabinet 100, thereby making the fan assembly 200 easier to disassemble and install, and facilitating the maintenance and replacement of the fan assembly 200.

[0039] In some embodiments, the fan assembly 200 can be connected with the main frame 101 by a bolt to realize the detachable connection between the fan assembly 200 and the main frame 101. In addition, the bolt connection has the advantages of low cost and good installation firmness.

[0040] AsFigure 4 , Figure 5 As shown, in some embodiments, the fan assembly 200 includes a fixing plate 201 and a first fan 202. The fixing plate 201 is detachably connected to the main frame 101. The first fan 202 is mounted on the fixing plate 201 and is located on the side of the fixing plate 201 near the top plate 102. The fixing plate 201 is provided with a ventilation hole 2011, which is opposite to the first fan 202. A wire is connected to the first fan 202.

[0041] The mounting plate 201 provides a base for the first fan 202 and facilitates the connection between the fan assembly 200 and the main frame 101. Furthermore, the first fan 202 is mounted on the side of the mounting plate 201 closest to the top plate 102, thus preventing it from being exposed outside the elevator control cabinet 10. This provides some protection for the first fan 202. The mounting plate 201 has ventilation holes 2011, which are positioned opposite to the first fan 202. When the first fan 202 is operating, external airflow can pass through the ventilation holes 2011, through the mounting plate 201, and then, driven by the first fan 202, enter the interior of the cabinet 100 through the first ventilation opening 1021, thereby providing air cooling for the electronic components inside the cabinet 100.

[0042] like Figure 6 As shown, in one embodiment, the fan assembly 200 further includes a protective net 203 connected to the fixing plate 201, which covers the ventilation hole 2011. The protective net 203 ensures airflow through the ventilation hole 2011 while blocking external objects, thus preventing them from colliding with or being drawn into the impeller of the first fan 202, thereby protecting the first fan 202.

[0043] like Figure 5 As shown, in some embodiments, the elevator control cabinet 10 also includes a control board (not shown in the figure), which is located inside the cabinet 100. The wiring terminal 300 is electrically connected to the control board via a cable. One end of the wire is provided with a connector 204, which is connected to the wiring terminal 300 by a plug-in connection.

[0044] The terminal block 300 is electrically connected to the control board via a cable. Thus, when the wires of the fan assembly 200 are electrically connected to the terminal block 300, the fan assembly 200 is electrically connected to the control board, so that the fan assembly 200 can be controlled by the control board.

[0045] In addition, one end of the wire is provided with a connecting connector 204, and the connecting connector 204 is connected to the wiring terminal 300 in a plug-in manner, that is, the connecting connector 204 and the wiring terminal 300 are connected by plugging, so as to realize the connection between the wire and the wiring terminal 300. When it is needed to disassemble the wire, the connecting connector 204 is pinched, and then the connecting connector 204 is pulled out of the wiring terminal 300 by using external force. Thus, it can be seen that the connecting connector 204 and the wiring terminal 300 are connected in a plug-in manner, which can provide convenience for the installation and disassembly of the wire and the wiring terminal 300, so as to improve the disassembly efficiency of the fan assembly 200 as a whole.

[0046] As shown in Figure 5 one of the embodiments, the connecting connector 204 is provided with a slot 2041, and the wiring terminal 300 is provided with a plug connector 301, and the plug connector 301 is plugged into the slot 2041. In this way, the plug-in connection between the connecting connector 204 and the wiring terminal 300 can be realized. Of course, in other embodiments, the wiring terminal 300 can be provided with the slot 2041, and the connecting connector 204 can be provided with the plug connector 301, and the plug-in connection between the connecting connector 204 and the wiring terminal 300 can also be realized.

[0047] As shown in Figure 4 some embodiments, the top plate 102 and the main body frame 101 jointly define a containing groove 105, and the fan assembly 200 is arranged in the containing groove 105. By arranging the fan assembly 200 in the containing groove 105 defined by the top plate 102 and the main body frame 101, the top plate 102 and the main body frame 101 can protect the fan assembly 200, so as to prevent external objects from touching the fan assembly 200 and causing damage or abnormal work of the fan assembly 200. In addition, the hidden design of the fan assembly 200 can be realized, so that the fan assembly 200 is not exposed, which is beneficial to keeping the appearance of the elevator control cabinet 10 simple, so as to improve the overall appearance of the elevator control cabinet 10.

[0048] As shown in Figure 5 some embodiments, the first ventilation opening 1021 is provided with a ventilation grille 1022. The ventilation grille 1022 is composed of a plurality of grid bars arranged at intervals, and the gaps between the grid bars are used for air flow passage. By arranging the ventilation grille 1022 at the first ventilation opening 1021, the air flow can pass through the first ventilation opening 1021 into the inside of the box body 100, and at the same time, external objects can be prevented from falling into the box body 100 through the first ventilation opening 1021.

[0049] As shown in Figure 7 , Figure 8As shown, in some embodiments, the main frame 101 comprises a back plate 1011, a first side plate 1012 and a second side plate 1013 connected with the back plate 1011. The elevator control cabinet 10 further comprises a mounting plate 400, a board card 500 and a second fan 600. The mounting plate 400 is arranged in the interior of the box body 100, and the mounting plate 400 is connected with the first side plate 1012 and the second side plate 1013. The board card 500 is provided with a power device 501, and the board card 500 is arranged on the mounting plate 400. The second fan 600 is arranged on the first side plate 1012. The first side plate 1012 is provided with a second ventilation opening 1014, and the second side plate 1013 is provided with a third ventilation opening 1015. The second fan 600 is opposite to the second ventilation opening 1014, and the second fan 600 is used for heat dissipation of the board card 500.

[0050] The mounting plate 400 is connected with the first side plate 1012 and the second side plate 1013 of the main frame 101, and the board card 500 is arranged on the mounting plate 400. In this way, the fixed connection between the board card 500 and the main frame 101 can be achieved. Since the board card 500 is provided with the power device 501, the power device 501 will generate heat during work, and therefore the heat dissipation problem of the board card 500 needs to be considered. In the embodiment, the second fan 600 is arranged on the first side plate 1012. The first side plate 1012 is provided with the second ventilation opening 1014, and the second side plate 1013 is provided with the third ventilation opening 1015. One of the second ventilation opening 1014 and the third ventilation opening 1015 can be used as an air inlet, and the other can be used as an air outlet. In this way, when the second fan 600 works, the external airflow will enter the interior of the box body 100 and pass through the board card 500, thereby air cooling and heat dissipation of the board card 500.

[0051] In some embodiments, the elevator control cabinet 10 further comprises a power element assembly (not shown in the figure). The board card 500 and the power element assembly are located on different sides of the mounting plate 400. The second fan 600 and the board card 500 are located on the same side of the mounting plate 400. The first ventilation opening 1021 and the power element assembly are located on the same side of the mounting plate 400.

[0052] The power element assembly can comprise at least one power element. Exemplarily, the power element is a rectifier, an inverter, a power terminal block, a contactor, a lightning protection plate, etc.

[0053] The board card 500 and the power element assembly are arranged on different sides of the mounting plate 400, so that heat generated by the board card 500 and heat generated by the power element assembly are not concentrated together. In addition, the second fan 600 and the board card 500 are located on the same side of the mounting plate 400, and the first vent 1021 and the power element assembly are located on the same side of the mounting plate 400, so that the second fan 600 can dissipate heat for the board card 500, and the fan assembly 200 can dissipate heat for the power element assembly, which is conducive to improving the heat dissipation efficiency of the elevator control cabinet 10.

[0054] As shown in Figure 7 one of the embodiments, the elevator control cabinet 10 further comprises a baffle 700, the baffle 700 and the board card 500 are located on the same side of the mounting plate 400, the baffle 700 is connected with the mounting plate 400, the baffle 700 and the mounting plate 400 jointly define a heat dissipation air duct, the board card 500 is located in the heat dissipation air duct, and the second vent 1014 and the third vent 1015 are located at two ends of the heat dissipation air duct.

[0055] By arranging the baffle 700, and using the baffle 700 and the mounting plate 400 to enclose the heat dissipation air duct, and the board card 500 being located in the heat dissipation air duct, the airflow provided by the second fan 600 can be more concentrated through the board card 500, so that the board card 500 is more effectively cooled, and thus better cooling effect and improved cooling efficiency can be obtained.

[0056] As shown in Figure 1 , Figure 7 one of the embodiments, the cabinet 100 comprises a cabinet panel 104, the cabinet panel 104 is connected with the first side plate 1012 and / or the second side plate 1013, the cabinet panel 104 is arranged opposite to the back plate 1011, the baffle 700 is located between the mounting plate 400 and the cabinet panel 104, and the baffle 700 is a transparent plate.

[0057] The cabinet panel 104 is connected to the front of the main frame 101, and the cabinet panel 104 is connected with at least one of the first side plate 1012 and the second side plate 1013. The cabinet panel 104 can be opened or detached, so that the internal structure of the elevator control cabinet 10 can be exposed. Generally, the board card 500 is provided with an indicator lamp, which is used to indicate the working state of the board card 500 or the working state of the power device 501 thereon.

[0058] The baffle 700 is a transparent plate, so that when the cabinet panel 104 is opened or detached, the indicator lamp on the board card 500 can be observed through the baffle 700, so that the working state of the board card 500 or the power device 501 thereon can be quickly understood.

[0059] Further, the wind shield 700 can be a transparent glass plate or an acrylic plate, so that the indicator light on the board card 500 can be observed through the wind shield 700.
