DETAILED DESCRIPTION

[0031] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many different ways other than those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0032] In combination with Figure 1 and Figure 2 It is shown that an embodiment of the present application provides an elevator control cabinet 100, which includes a cabinet body 110, a control module 120, a drive module 130, a heat dissipation component 140, and a power supply module 150.

[0033] The control module 120, the drive module 130, the heat dissipation component 140, and the power supply module 150 are all arranged in the cabinet body 110. The power supply module 150 is electrically connected with the drive module 130 and the control module 120, and the power supply module 150 is used to supply power to the control module 120 and the drive module 130. The drive module 130 and the control module 120 are electrically connected, the control module 120 is used to process information of external signals, and according to the external signals, the control module 120 sends control instructions to the drive module 130, so that the drive module 130 controls the operation of elevator components according to the control.

[0034] The at least partial control module 120, the at least partial drive module 130, and the at least partial heat dissipation assembly 140 are sequentially stacked along the thickness direction Y of the cabinet body 110, so that the heat dissipation assembly 140 can dissipate heat for the drive module 130 and the control module 120. The power module 150 and the control module 120 are sequentially arranged along the height direction X. That is, the power module 150 and the drive module 130 are also sequentially arranged along the height direction X. Among them, the power module 150 is arranged close to the top side 111, and the control module 120 and the drive module 130 are arranged close to the bottom side 112.

[0035] It can be understood that integrating the control part into the control module 120, integrating the drive part into the drive module 130, and integrating the power supply part into the power module 150, and the stacked arrangement of the at least partial control module 120 and the at least partial drive module 130, can improve the integration degree between the control module 120 and the drive module 130, thereby optimizing the space layout in the elevator control cabinet 100, and at the same time facilitating the reduction of the length of the electrical connection between the control module 120 and the drive module 130. The wire and the like, thereby facilitating the more simple wiring arrangement of the elevator control cabinet 100, and effectively preventing excessive entanglement between the wires.

[0036] Further, generally, the drive module 130 and the control module 120 are more obvious in terms of electrical heating effect than the power module 150, and generate more heat energy. Based on this, the heat dissipation assembly 140 is stacked below the drive module 130, which is beneficial to improve the heat dissipation pertinence in the elevator control cabinet 100, thereby improving the heat dissipation efficiency.

[0037] In addition, the power module 150 and the control module 120 are sequentially arranged along the height direction X, which is beneficial to the disassembly and maintenance of the control module 120 and the power module 150, without the need to disassemble each module in the elevator control cabinet 100 layer by layer, thereby reducing the difficulty of maintenance. At the same time, the thickness of the elevator control cabinet 100 is reduced, which is beneficial to improve the thinness performance of the elevator control cabinet 100.

[0038] It should be noted that the electrical connection mode between the control module 120, the drive module 130, and the power module 150 can be through wires, conductive glue, and the like. Electrical connection mode can also refer to some examples in which the drive module 130 and the control module 120 can be electrically connected through wireless communication and the like.

[0039] In an example scenario, the cabinet body 110 is provided with a front surface and a back surface opposite to each other along the thickness direction Y, the control module 120 is arranged towards the front surface, and the heat dissipation assembly 140 is arranged towards the back surface. The front surface of the cabinet body 110 can be provided with a cabinet door to close the cabinet body 110. In this way, the maintenance personnel can conveniently maintain the control module 120 and the drive module 130 from the front surface, the heat dissipation assembly 140 does not interfere with the maintenance, and the maintenance efficiency is improved. For example, when the control module 120 needs to be maintained, the cabinet door is only needed to be opened, and the control module 120 can be directly disassembled and maintained, and the heat dissipation assembly 140 does not interfere with the maintenance space of the control module 120.

[0040] In other embodiments, the elevator control cabinet 100 can further include a hanging assembly connected to the back surface of the cabinet body 110, so that the cabinet body 110 can be installed on the wall or in the shaft, etc. by wall mounting, thereby increasing the application installation scenarios of the elevator control cabinet 100.

[0041] In some embodiments, the control module 120 is arranged on the first surface of the cabinet body 110, and the drive module 130 is arranged on the second surface of the cabinet body 110. Figure 2 The elevator control cabinet 100 further includes a bearing frame 160 connected with the cabinet body 110. The bearing frame 160 is provided with a first surface and a second surface opposite to each other along the thickness direction Y. The control module 120 and the drive module 130 are stacked and arranged in the mounting shell, and the control module 120 and the drive module 130 are connected and matched with the first surface, so that the control module 120 and the drive module 130 are connected with the cabinet body 110 through the bearing frame 160.

[0042] In this way, the control module 120 and the drive module 130 are integrated and arranged on the bearing frame 160, so that the integration performance of the control module 120 and the drive module 130 can be improved, the connection strength between the control module 120 and the drive module 130 is improved, the space layout in the elevator control cabinet 100 is optimized, and the reliability and stability of the system are improved.

[0043] Further, in one of the embodiments, the bearing frame 160 is provided with a recessed portion 161 arranged on the second surface. Specifically, the recessed portion 161 is recessed from the second surface towards the first surface, and the heat dissipation assembly 140 is arranged in the recessed portion 161. Figure 2

[0044] In this way, the heat dissipation assembly 140 is arranged on the second surface, and the recessed portion 161 is arranged, so that a larger heat dissipation space is provided for the heat dissipation assembly 140, the heat dissipation efficiency is improved, the internal temperature of the control cabinet is effectively reduced, and the reliability and service life of each module in the elevator control cabinet 100 are improved.

[0045] ​Further, the bearing frame 160 sets the control module 120 and the drive module 130 on the first surface, and sets the heat dissipation assembly 140 in the avoiding recess 161, which is advantageous to prevent displacement, collision or mutual superposition between the modules, and to prevent damage, and to improve the working reliability of the modules of the elevator control cabinet 100.

[0046] In other embodiments, as shown in Figure 2 The cabinet 110 is provided with a first air vent 113 and a second air vent 114 along the length direction Z of the cabinet 110. The heat dissipation assembly 140 includes a first heat dissipation member 141 and a second heat dissipation member 142, the first heat dissipation member 141 is installed and matched with the first air vent 113, and the second heat dissipation member 142 is installed and matched with the second air vent 114. The first heat dissipation member 141 and the second heat dissipation member 142 are spaced apart to form an air duct, and at least part of the space where the drive module 130 is located is in communication with the air duct.

[0047] It can be understood that the cabinet 110 is provided with the first air vent 113 and the second air vent 114 along the length direction Z to form an air convection channel, which is advantageous to the discharge of hot air and the entry of cold air, and to improve the heat dissipation efficiency. And at least part of the drive module 130 is arranged in the air duct, and the heat is taken away by the air flow, which further improves the heat dissipation effect. In this way, the air duct design can guide the airflow to flow through the heating elements such as the drive module 130, avoid local heat accumulation, and ensure uniform temperature distribution in the cabinet 110.

[0048] It should be noted that the first heat dissipation member 141 and the second heat dissipation member 142 can be, but are not limited to, a blowing member or an exhaust member, and can also be a radiator, a semiconductor refrigeration sheet, or a combination of different types, which is not limited here.

[0049] In an embodiment, as shown in Figure 2 The first heat dissipation member 141 includes a plurality of heat dissipation fans. In an example, the heat dissipation fan can be a cold air blowing into the cabinet 110 from the outside to realize the input of external cold quantity into the cabinet 110 and heat exchange with the heating elements such as the drive module 130 in the cabinet 110 (at this time, the heat dissipation fan is used to realize the function of the blowing member). In another example, the heat dissipation fan can also be a heat blowing out of the heating elements of the drive module 130 in the cabinet 110 to the outside to realize the heat dissipation function of the cabinet 110 (at this time, the heat dissipation fan is used to realize the function of the exhaust member).

[0050] Therefore, the structure of the heat dissipation fan is simple, and the heat dissipation fan is convenient to arrange, which is beneficial to reduce the arrangement cost of the elevator control cabinet 100. It should be noted that the number of the heat dissipation fan can be one or more, and the heat dissipation fan can be electrically connected with the power module 150, or the heat dissipation fan can not be electrically connected with the power module 150 when the heat dissipation fan functions as an air suction component (i.e., the heat dissipation fan is driven to rotate by the temperature difference between the inside and outside of the cabinet body 110), and the like. The connection mode can be selected according to different design requirements.

[0051] In an example scenario, the first heat dissipation component 141 includes at least two heat dissipation fans, and the at least two heat dissipation fans are sequentially and spaced apart in the height direction X. Therefore, the sequential arrangement of the plurality of heat dissipation fans is beneficial to increase the heat dissipation space, thereby improving the heat dissipation efficiency in the cabinet body 110.

[0052] In another embodiment, the second heat dissipation component 142 can be at least one of a finned heat sink, an air-cooled heat sink, or the like. Accordingly, referring to the example description of the first heat dissipation component 141, the second heat dissipation component 142 can also function as a blower component or an air suction component.

[0053] It should be noted that the second heat dissipation component 142 can be electrically connected with the power module 150, or can not be electrically connected with the power module 150. In addition, the structure of the second ventilation opening 114 can be a ventilation hollow hole, or can be a ventilation fence structure, and the like, and the former is not limited too much herein.

[0054] In other embodiments, Figure 2 at least part of the first heat dissipation component 141 and at least part of the second heat dissipation component 142 are staggered in the height direction X. That is, the center of gravity of at least part of the first heat dissipation component 141 and the center of gravity of at least part of the second heat dissipation component 142 are not located at the same height. Therefore, the first heat dissipation component 141 and the second heat dissipation component 142 are staggered in the height direction X, so that the air flow forms an interlaced flow when passing through the heat dissipation component, avoiding the air flow directly passing through the heat dissipation component without fully contacting the heat dissipation surface, thereby improving the heat dissipation efficiency of the elevator control cabinet 100.

[0055] In combination with any of the above embodiments of the bearing frame 160, Figure 1 and Figure 3As shown, the bearing frame 160 is provided with a first side 162 and a second side 163 opposite to each other along the length direction Z, the first side 162 is arranged close to the top side 111, and the second side 163 is arranged close to the bottom side 112. The elevator control cabinet 100 further comprises a connecting piece 170, the connecting piece 170 comprises a first body 171 connected to the first face, the first body 171 is arranged close to the first side 162, and the height of the first body 171 gradually decreases in the direction from the first side 162 to the second side 163, so that the first body 171 forms an inclined surface structure 171a, the first body 171 is provided with a ventilation groove 171b, the inclined surface structure 171a is provided with the ventilation groove 171b, and the ventilation groove 171b is in communication with the air duct, and the ventilation groove 171b is arranged opposite to at least part of the drive module 130.

[0056] It can be understood that, through the arrangement of the ventilation groove 171b, the drive module 130 can be in flow communication with the air duct through the ventilation groove 171b, so that the cold air or hot air can exchange heat between the ventilation groove 171b, the air duct and the drive module 130, ensuring that the drive module 130 with large heat generation can directly obtain the coverage of cooling air flow, reducing its working temperature, avoiding performance degradation or damage caused by overheating, and improving the heat dissipation efficiency in the elevator control cabinet 100.

[0057] Further, the first body 171 of the connecting piece 170 is designed as an inclined surface structure 171a, and the height gradually decreases in the direction from the first side 162 to the second side 163, which can guide the airflow to flow along the inclined surface, and is beneficial to form the airflow flow path. Specifically, if the hot airflow needs to pass through the first body 171 to flow to other positions, it needs to pass through a certain airflow climbing section, and at this time, the movement resistance of the hot airflow is large, while the cold airflow entering the drive module 130 from the air duct can flow downhill along the inclined surface structure 171a, reducing the flow resistance of the cold airflow, and being beneficial to the formation of the heat dissipation path, and then effectively improving the heat exchange quality and efficiency in the elevator control cabinet 100.

[0058] In addition, in some embodiments, it is found Figure 1 and Figure 3 The connecting piece 170 further comprises a second body 172 connected to the first face. The drive module 130 comprises a circuit board 131 and a functional component 132, and the power supply module 150 and the control module 120 are electrically connected to the circuit board 131. The circuit board 131 is electrically connected to the functional component 132, the circuit board 131 is in abutting connection with the second body 172, and there is a flow communication gap between the circuit board 131 and the functional component 132, and the flow communication gap is in communication with the ventilation groove 171b and the air duct.

[0059] It is understood that when the circuit board 131 drives the functional component 132, the circuit board 131 is connected to the first body 171, and the functional component 132 is connected and cooperated with the first surface, so that there is a flow gap between the circuit board 131 and the functional component 132. This flow gap can communicate with the ventilation slot 171b and the air duct, so that the cold air in the air duct can fully enter between the circuit board 131 and the functional component 132, so as to fully dissipate heat from the drive module 130, increase the heat dissipation area of ​​the drive module 130, and thus improve the heat dissipation efficiency of the elevator control cabinet 100.

[0060] It should be noted that in the above embodiments, the first body 171 and the second body 172 can be connected or not connected. Furthermore, the connection between the first body 171 and the second body 172 can be, but is not limited to, integral molding connection, bonding, snap-fit, etc., and is not further limited here.

[0061] In one of the implementation methods, combined Figure 2 as well as Figure 3 In conjunction with the circuit board 131 and functional components 132 in the above embodiments, the support frame 160 is provided with a third cutout portion 164, in which at least some of the functional components 132 are inserted. Thus, by inserting at least some of the functional components 132 into the third cutout portion 164, the size occupied by the drive module 130 in the thickness direction Y can be reduced, thereby contributing to the thinning and lightening of the elevator control cabinet 100.

[0062] Furthermore, in conjunction with the arrangement of the ventilation slot 171b and the air duct in the above embodiments, at least some functional components 132 are inserted into the third hollow portion 164. It is understood that the thermal effect of functional components 132 is more pronounced than that of the circuit board 131, meaning that functional components 132 dissipate more heat. Based on this, by inserting at least some functional components 132 into the third hollow portion 164, one side of the functional component 132 along the thickness direction Y can circulate and cooperate with the air duct, receiving sufficient heat exchange from the cold air in the air duct; the other side can circulate and cooperate with the ventilation slot 171b, thereby receiving heat exchange from the cold air blown from the ventilation slot 171b. This increases the heat exchange area of ​​the functional component 132 and eliminates the need for additional heat dissipation components, thus improving the heat dissipation efficiency of the functional component 132.

[0063] It should be noted that when at least some functional components 132 are inserted into the third hollow portion 164, the functional components 132 can be connected and engaged with the inner sidewall of the third hollow portion 164, or they can be not connected and engaged, depending on different production requirements. In the above embodiments, the functional components 132 can be, but are not limited to, any one or any combination of an insulated gate bipolar transistor module, a capacitor assembly, a braking unit or braking resistor, a current sensor, etc.

[0064] In an example, the bearing frame 160 is a metal frame, and when the functional component 132 is inserted into the third hollow part 164, at least part of the functional component 132 abuts against the side wall of the third hollow part 164, so that the functional component 132 can be in thermal contact with the metal frame. The thermal conductivity of the metal frame is greater than or equal to the thermal conductivity of the functional component 132.

[0065] In this way, when the functional component 132 is inserted into the third hollow part 164, at least part of the functional component 132 abuts against the side wall of the third hollow part 164, forming a direct contact thermal conduction path, reducing thermal resistance and improving thermal conduction efficiency. Further, the thermal conductivity of the metal frame is greater than or equal to the thermal conductivity of the functional component 132, which can quickly conduct the heat generated by the functional component 132 away, avoiding the accumulation of heat inside the functional component 132, and improving the working reliability of the functional component 132.

[0066] In another example, the functional component 132 is in abutting contact with the heat dissipation component 140, so that the functional component 132 is in thermal contact with the heat dissipation component 140. In this way, on the one hand, the direct contact thermal conduction method is more efficient than the conduction through air or other media, and can quickly transfer the heat generated by the functional component 132 to the heat dissipation component 140. On the other hand, the heat dissipation component 140 (such as a heat sink or the like) has a large heat dissipation area and high heat dissipation capacity, which can quickly dissipate heat to the surrounding environment, which is conducive to quickly reducing the working temperature of the functional component 132 to avoid performance degradation or damage of the functional component 132 due to overheating.

[0067] In order to improve the use convenience of the elevator control cabinet 100, in some embodiments, as shown in Figure 4 The elevator control cabinet 100 further includes a control switch component 180, which is electrically connected with at least one of the control module 120, the drive module 130, and the power module 150, so that the maintenance personnel can output control signals to at least one of the control module 120, the drive module 130, and the power module 150 through the control switch component 180. The control switch component 180 is arranged close to the top side 111, and at least part of the control switch component 180 is exposed and arranged on the outer surface of the cabinet body 110. In this way, the maintenance personnel can control the control switch component 180 on the outer surface of the cabinet body 110 without opening the cabinet body 110, which improves the convenience of the maintenance personnel's operation.

[0068] In some embodiments, the control switch component 180 can include any one or any combination of a main power switch, a contactor, a safety return switch 181, an emergency stop switch 182, a temperature switch, and the like.

[0069] Wherein, the main power switch refers to a switch for controlling the on-off of the main power supply of the elevator control cabinet 100; the contactor refers to a switch for communicating with the control module 120, so that the on-off of the power supply of the motor, lighting, fan and other equipment can be controlled; the safety loop switch 181 refers to a switch for electrically connecting the driving module 130 or the control module 120, and when the safety state of the elevator (such as door lock, limit, emergency stop, etc.) is abnormal, the safety loop switch 181 is immediately disconnected, so that the elevator operation can be stopped; the emergency stop switch 182 refers to a switch that can immediately cut off the power supply of the elevator and stop the operation of the elevator in an emergency; the temperature switch refers to a switch for monitoring the temperature of the inside of the control cabinet or the key components, which triggers a protection action such as shutdown or cooling when the temperature exceeds the set value.

[0070] In an example scenario, as shown in Figure 2 and Figure 4 , the power supply module 150 includes a switching power supply 151 and a safety electronic board 152, the safety electronic board 152 is provided with a safety loop, and the switching power supply 151 is electrically connected with the safety loop. When the safety loop is in an open state, the switching power supply 151 is in a power-off state, so that the switching power supply 151 cannot supply power to the control module 120 and the driving module 130. When the safety loop is in a closed state, the switching power supply 151 is in a power-on state, so that the switching power supply 151 can supply power to the control module 120 and the driving module 130. The control switch assembly 180 includes a safety loop switch 181, the safety loop switch 181 is protrudingly arranged on the outer surface of the cabinet body 110, and the safety loop switch 181 is electrically connected with the safety loop, so that the safety loop is switched between the open state and the closed state through the safety loop switch 181.

[0071] In this way, maintenance personnel can directly stop the elevator components through the safety loop switch 181, which is beneficial to efficiently and quickly control the operation of the elevator and improve the maintenance efficiency.
