[0040] like Figures 1 to 4 As shown, according to an embodiment of the present invention, an elevator control drive device is proposed.
[0041] The elevator control driving device comprises a cabinet 10, a mounting plate 20, a driving module 30, a power module 40 and a control module 50. Specifically, the control module 50 processes the input and output of external signals and answers the signals, and sends control instructions to the driving module 30 according to the signals, so that the driving module 30 controls the operation of the elevator components to realize the up and down operation of the elevator, etc. The power module 40 is used to supply power to the control module 50 and the driving module 30.
[0042] In the embodiment, the cabinet 10 is in the form of a box-shaped structure, and the mounting plate 20 is in the form of a plate-shaped structure. The mounting plate 20 is fixedly installed on the cabinet 10, the front surface 21 of the mounting plate 20 is located on the side away from the cabinet 10, and the back surface of the mounting plate 20 is arranged on the side facing the cabinet 10 and defines a heat dissipation air duct 11 with the cabinet 10. The driving module 30 and the power module 40 are arranged in the heat dissipation air duct 11, and the heat generated by the driving module 30 and the power module 40 is dissipated through the airflow in the heat dissipation air duct 11. The control module 50 is installed on the front surface 21 of the mounting plate 20, so that the control module 50 is located outside the heat dissipation air duct 11, thereby reducing the influence of the heat dissipated by the power module 40 and the driving module 30 on the control module 50, reducing the working environment temperature of the control module 50, and being conducive to improving the operation stability of the electronic devices on the control module 50 and reducing the elevator operation failure.
[0043] It should be noted that the control module 50 can be arranged at any position of the front surface 21 of the mounting plate 20, for example, the control module 50 can be arranged close to any one of the lower edge, the upper edge, the left edge or the right edge of the front surface 21, or the control module 50 can be arranged in the middle region of the front surface 21.
[0044] The driving module 30 and the power module 40 can be arranged at any position of the back surface of the mounting plate 20, and the driving module 30 and the power module 40 can be arranged in different regions of the back surface of the mounting plate 20, respectively, for example, the driving module 30 and the power module 40 can be arranged in different regions of the back surface of the mounting plate 20 in sequence in the up-down direction, or the driving module 30 and the power module 40 can be arranged in different regions of the back surface of the mounting plate 20 in sequence in the left-right direction. Understandably, the driving module 30 and the power module 40 can be stacked on the back surface of the mounting plate 20 in a direction perpendicular to the mounting plate 20.
[0045] In some embodiments of the present application, as Figure 3As shown, the power module 40 and the driving module 30 are arranged in sequence along the direction parallel to the mounting plate 20, so that the power module 40 and the driving module 30 are respectively located in different regions in the heat dissipation air duct 11, the contact area of the power module 40 and the driving module 30 with the airflow in the heat dissipation air duct 11 is increased, and thus the heat dissipation effect is improved. In the direction perpendicular to the mounting plate 20, the control module 50 and the driving module 30 are stacked, and the mounting plate 20 is provided with a plurality of wire passing holes 22 for the wires to pass through, so that the control module 50 can be electrically connected with the driving module 30 and the power module 40 through the wire passing holes 22 on the mounting plate 20, the layout of the components and the modules of the control driving device is optimized, the wiring between the internal components is more simple, and the cables are prevented from being entangled with each other; in addition, the modules and the components in the modules have a hierarchical layout, the volume of the control cabinet can be effectively reduced, the space utilization is greatly improved, the length of the connecting cables between the circuit boards is reduced, the working hours and the cost required for production and wiring are reduced, and the difficulty of disassembly and maintenance is reduced.
[0046] In some embodiments of the present application, as shown in Figure 1 and Figure 3 The cabinet body 10 is further provided with an air inlet 12 and an air outlet 13, the air inlet 12 and the air outlet 13 are communicated with the heat dissipation air duct 11, and the air inlet 12 and the air outlet 13 are respectively located at two ends of the heat dissipation air duct 11.
[0047] In an exemplary embodiment, the air inlet is arranged at the bottom of the cabinet body, the air outlet is arranged at the top of the cabinet body, the power module and the driving module are arranged in sequence along the extension direction of the heat dissipation air duct, the driving module is arranged close to the air inlet, and the power module is arranged close to the air outlet. In the embodiment, the air outlet is arranged at the top of the cabinet body. The airflow in the heat dissipation passage flows from bottom to top. Since the density of hot air is relatively lower than that of cold air, the flow of hot airflow in the heat dissipation air duct is smoother.
[0048] In another exemplary embodiment, as shown in Figure 1 and Figure 3As shown, the air inlet 12 is arranged at the top of the cabinet 10, the air outlet 13 is arranged at the bottom of the cabinet 10, the power module 40 and the driving module 30 are arranged in sequence along the extending direction of the heat dissipation air duct 11, the driving module 30 is arranged close to the air outlet 13, and the power module 40 is arranged close to the air inlet 12. Since the driving module 30 has a large amount of heat, the driving module 30 is arranged close to the air outlet 13, so that the airflow in the heat dissipation air duct 11 is discharged from the heat dissipation air duct 11 after heat exchange with the driving module 30, the residence time of the high-temperature air after heat exchange in the cabinet 10 is reduced, and therefore, the influence of the high-temperature air after heat exchange on the electronic elements in the power module 40 and the driving module 30 is reduced as much as possible, and the stability of the power module 40 and the driving module 30 in operation is improved.
[0049] In the embodiment, the air inlet 12 is arranged at the top of the cabinet 10, the air outlet 13 is arranged at the bottom of the cabinet 10, and the number of the air inlets 12 is two. One fan 85 is arranged in each air inlet 12, and the fan 85 provides driving force to generate relatively strong airflow in the heat dissipation air duct 11 to improve the heat dissipation efficiency of the power module 40 and the driving module 30.
[0050] In other embodiments of the present application, the fan can also be arranged at the air outlet, or the fan can be arranged at both the air outlet and the air inlet to increase the strength of the airflow in the heat dissipation air duct.
[0051] In some embodiments of the present application, as shown in Figure 3 As shown, the elevator control driving device further comprises a heat dissipation module 60. Specifically, the heat dissipation module 60 is connected with the driving module 30, and the heat dissipation module 60 is used for dissipating heat of the driving module 30. In the embodiment, the heat dissipation module 60, the control module 50 and the driving module 30 are arranged in three layers in the direction perpendicular to the mounting plate 20, which is beneficial to the wiring connection between the circuit boards on each layer, reduces the number and length of the cables between the circuit boards on each layer, saves the cable material cost, and reduces the wiring difficulty.
[0052] In the embodiment, the heat dissipation module 60 is arranged at the side of the driving module 30 away from the mounting plate 20, so that the driving module 30 is closer to the control module 50, which is beneficial to the wiring between the driving module 30 and the control module 50. Moreover, the heat dissipation module 60 is arranged away from the control module 50, so as to reduce the influence of the heat radiation of the heat dissipation module 60 on the control module 50.
[0053] In other examples, the heat dissipation module 60 can also be arranged at the side of the driving module 30 away from the mounting plate 20.
[0054] In some embodiments of the present application, as shown in Figure 2 and Figure 4As shown, the driving module 30 comprises a driving board 31, a single-tube IGBT module 32, a driving control board 33, and a rectifier module 34. The heat dissipation module 60 comprises a first heat dissipation component 61 and a second heat dissipation component 62.
[0055] It should be noted that IGBT (Insulated Gate Bipolar Transistor) is a composite full-control voltage-driven power semiconductor device composed of a bipolar junction transistor (BJT) and an insulated gate field effect transistor (MOS). The IGBT module is a modular semiconductor product packaged by a specific circuit bridge between IGBT (insulated gate bipolar transistor chip) and FWD (free-wheeling diode chip). The packaged IGBT module is directly applied to frequency converters and other devices. In the present application, the single-tube IGBT module 32 is integrated on the driving board 31 to replace the packaged IGBT module, thereby reducing the cost.
[0056] Specifically, the driving board 31 is a circuit board carrier of the single-tube IGBT module 32, the driving control board 33, and the rectifier module 34. By integrating the single-tube IGBT module 32, the driving control board 33, and the rectifier module 34 on the driving board 31, the driving module 30 has rectification, inversion, and driving control functions, thereby improving the integration of the driving module 30, making the wiring between the components of the driving module 30 more simple, preventing the cables from being entangled with each other, and reducing the volume occupied by the driving module 30.
[0057] Specifically, the driving board 31 is spaced apart from the mounting plate 20 to prevent breakdown, or an insulating member (such as insulating paper) is arranged between the driving board 31 and the mounting plate 20 to separate the driving board 31 from the mounting plate 20, thereby preventing breakdown. The driving control board 33 is connected to the driving board 31 and located between the driving board 31 and the mounting plate 20. The single-tube IGBT module 32 and the rectifier module 34 are installed on the driving board 31 and located on the side of the driving board 31 away from the mounting plate 20. Therefore, the single-tube IGBT module 32 and the rectifier module 34 are further away from the control module 50, thereby reducing the influence of the heating electrical elements on the control module 50.
[0058] In detail, the single-tube IGBT module 32 includes a plurality of fixing members 321 and a plurality of IGBT single tubes 322. The fixing member 321 is substantially square in shape, and at least one embedding groove matched with the IGBT single tube 322 is arranged on each fixing member 321. The fixing member 321 is fixedly connected with the driving board 31, and the embedding groove is arranged on the side of the fixing member 321 away from the driving board 31. The plurality of IGBT single tubes 322 are embedded in the embedding grooves, so that the IGBT single tubes 322 are fixed relative to the driving board 31. The first heat dissipation assembly 61 is in abutment with the IGBT single tube 322, so that the heat generated by the IGBT single tube 322 is transferred to the first heat dissipation assembly 61 for dissipation, and the IGBT single tube 322 is always kept within a suitable temperature range, so as to ensure that the single-tube IGBT module 32 can operate normally. Each IGBT single tube 322 has a pin, and the IGBT single tube 322 is electrically connected with the driving board 31 through the pin. In the embodiment, each fixing member 321 is provided with two embedding grooves, so that each fixing member 321 can install two IGBT single tubes 322. The plurality of IGBT single tubes 322 are arranged in a linear arrangement on the driving board 31, and at least one row of IGBT single tubes 322 is arranged on the driving board 31. It should be noted that, by using a plurality of IGBT single tubes 322 instead of a conventional integrated and packaged power module, the problem of high cost of the motor controller caused by the selection of the packaged power module is avoided, and the volume required by the power module is also reduced.
[0059] In one example embodiment, as shown in FIG. 1, Figure 2 The driving board 31 is provided with two rows of IGBT single tubes 322, and each row of IGBT single tubes 322 needs a plurality of fixing members 321. The driving board 31 is provided with a plurality of connecting holes 311, and each connecting hole 311 corresponds to a fixing member 321. The connecting hole 311 is a circular through hole. The fixing member 321 includes a body portion and a connecting portion 3211. The connecting portion 3211 is located on the side of the body portion facing the driving board 31, and the embedding groove is formed on the side of the body portion away from the driving board 31. In the embodiment, the connecting portion 3211 is a columnar structure protruding from the body portion, and the connecting portion 3211 is inserted into the connecting hole 311 to connect the fixing member 321 and the driving board 31. The connecting hole 311 and the connecting portion 3211 are provided with corresponding foolproof structures. On the one hand, the relative position of the fixing member 321 and the driving board 31 is limited, the installation accuracy of the IGBT single tube 322 is improved, and on the other hand, the upper and lower rows of IGBT single tubes 322 are prevented from being confused during installation. In the example, the foolproof mechanism includes a limiting groove formed on the inner wall of the connecting hole 311 and a limiting block protruding from the outer side wall of the connecting portion 3211. The limiting block and the limiting groove are matched to achieve foolproof installation of the fixing member 321 and the driving board 31.
[0060] In the embodiment, the drive module 30 further comprises a terminal row 35 arranged at the edge of the drive board 31, the rectifier module 34 is arranged on the side of the drive board 31 close to the terminal row 35, the single-tube IGBT module 32 is electrically connected with the power module 40, and the single-tube IGBT module 32 is arranged between the rectifier module 34 and the power module 40.
[0061] Specifically, the rectifier module 34 comprises a capacitor board 341, a rectifier bridge 342, a first insulating paper 343, a second insulating paper 344 and a second heat dissipation component 62, the capacitor board 341 is connected with the drive board 31, the current input end of the capacitor board 341 is electrically connected with the terminal row 35, the current output end of the capacitor board 341 is electrically connected with the single-tube IGBT module 32, and the rectifier bridge 342 is arranged on the capacitor board 341 and electrically connected with the current input end and the current output end respectively. In detail, the three-phase alternating current input from outside is connected to the RST three-phase power input of the terminal row 35 through a cable, the three-phase alternating current is converted into two-phase direct current by flowing through the rectifier bridge 342 on the capacitor board 341, the two-phase direct current is connected in parallel with the electrolytic capacitor on the capacitor board 341, and then flows through the single-tube IGBT module 32 on the drive board 31 to be converted into three-phase alternating current, the three-phase alternating current flows back to the UVW three-phase of the terminal row 35 of the drive board 31, and then is connected to the elevator traction machine through a cable. It should be noted that the power module 40 takes power from the input three-phase alternating current of the drive board 31 and then converts it into power of various voltage levels to supply power to various parts in the drive module 30 and the control module 50.
[0062] In the embodiment, the current input end and the current output end of the capacitor board 341 are electrically connected with the drive board 31 through copper studs. In addition to conducting electricity, the copper studs also fixedly connect the capacitor board 341 with the drive board 31, so as to reduce the connecting parts between the capacitor board 341 and the drive board 31, make the structure more simple and compact, and facilitate the miniaturization design of the drive module 30.
[0063] Further, the first insulating paper 343 is arranged between the capacitor board 341 and the drive board 31 to realize the insulation between the drive board 31 and the capacitor board 341. The second insulating paper 344 is arranged between the capacitor board 341 and the second heat dissipation component 62 to realize the insulation between the capacitor board 341 and the metal plate of the second heat dissipation component 62.
[0064] In the embodiment, the first heat dissipation assembly 61 comprises a heat-conductive support plate 611 and a first heat sink 612 attached to the heat-conductive support plate 611, and the heat-conductive support plate 611 is configured to transfer heat of the single-tube IGBT module 32 to the first heat sink 612. The heat-conductive support plate 611 can be made of ceramic, composite material or other material with good heat conductivity. The second heat dissipation assembly comprises a second heat sink 621, which is in contact with the rectifier bridge 342, and the second heat sink 621 is configured to dissipate heat of the rectifier bridge 342.
[0065] In some embodiments of the present application, as shown in Figure 1 and Figure 4 The elevator control driving device further comprises a first support 71 and a second support 72.
[0066] Specifically, the first support 71 is in the form of a plate, which comprises a first main body part 711 and first side edge parts 712 formed on both sides of the first main body part 711. The edges of the first main body part 711 are bent by 90 degrees towards the same side to form the first side edge parts 712. The two first side edge parts 712 are respectively in contact with the two inner walls of the cabinet 10 opposite to each other, and corresponding through holes are provided on the first side edge parts 712 and the cabinet 10 to fix and connect the first support 71 and the cabinet 10 by connecting members such as bolts, rivets, etc. The first main body part 711 is further provided with connecting columns 91, and the power module 40 comprises an integrated power panel. The integrated power panel is provided with mounting holes 92 corresponding to the connecting columns 91.

[0068] In the embodiment, the first support 71 and the second support 72 are sequentially arranged in a direction parallel to the mounting plate 20, and the first support 71 and the second support 72 are both arranged spaced apart from the mounting plate 20, so as to form an assembly space between the first support 71 and the mounting plate 20 and between the second support 72 and the mounting plate 20, and to form gaps for gas flow between the power module 40 and the mounting plate 20 and between the driving module 30 and the mounting plate 20, so that in the heat dissipation air duct 11, the two sides of the power module 40 and the driving module 30 are both formed with air ducts for gas flow, which is beneficial to sufficient heat dissipation of the power module 40 and the driving module 30.
[0069] In the embodiment, the elevator control capable device further comprises a third bracket 73 in the form of a plate, which comprises a third main body portion and third side edge portions 732 formed on both sides of the third main body portion, the edges of the third main body portion are bent by 90 degrees towards the same side to form the third side edge portions 732, the two third side edge portions 732 are respectively in abutment with the two inner walls opposite to each other of the cabinet body 10, and corresponding through holes are provided on the third side edge portions 732 and the cabinet body 10 to fixedly connect the third bracket 73 and the cabinet body 10 by connecting members such as bolts, rivets, etc. One side of the third bracket 73 facing the driving plate 31 is used to fix the capacitive plate 341, and the other side of the third bracket 73 away from the driving plate 31 is used to fix the second heat sink 621, and the rectifier bridge 342 passes through the third bracket 73 and abuts against the second heat sink 621 to achieve heat dissipation of the rectifier module 34.
[0070] In some embodiments of the application, the control module 50 comprises a main control board 51 and a PG card 52. Specifically, the front surface 21 of the mounting plate 20 is provided with a plurality of connecting columns 91, and the main control board 51 is provided with mounting holes 92 corresponding to the connecting columns 91, so as to detachably mount the main control board 51 on the mounting plate 20. The main control board 51 is connected to the driving module 30 through a wire to interact control signals, and controls the driving module 30 to realize the control functions of the elevator hoisting machine driving the car to ascend, descend, stop and open the door smoothly and to realize shock absorption. The PG card 52 (PG, Pulse Generator) is connected to the main control board 51 through copper studs. The PG card 52 is connected to the hoisting machine through a data bus DB to collect information such as feedback speed of the hoisting machine motor, and transmits the speed and other information to the main control board 51 to control the operation of the hoisting machine.
[0071] In some embodiments of the application, as shown in Figure 1 Specifically, the car unexpected movement protection module 83, the emergency stop button 81 and the change-over switch 82 are fixedly installed on the front surface 21 of the mounting plate 20 and electrically connected with the main control board 51, and the safety torque cancellation module 84 is fixedly provided on the driving plate 31 and electrically connected with the driving plate 31.
[0072] Specifically, the car unintended movement protection module 83 (UCMP, Unintended car movement protection system) is connected to the elevator car through a wire harness to achieve the functions of early door opening and detection of door lock short circuit. Specifically, when the elevator is in the level position and the door is open, if the elevator moves unexpectedly, the car unintended movement protection module 83 immediately activates protection and stops the elevator from running, providing an additional safety guarantee for passengers. The technical principle of the car unintended movement protection module 83 is that when the car door is opened and passengers enter the car, the function of the device is activated, and through sensor signal control, the car is reliably fixed on the elevator guide rail to prevent accidental movement of the car. After the car door is closed, the sensor resets the car protection device, and then the car continues to run, so that the car door and the protection device can run synchronously, achieving real-time protection.
[0073] The safe torque off module 84 (STO, Safe Torque Off) can control the frequency converter to shut down the torque output when the motor stops running, avoiding safety accidents caused by accidental start. In elevator applications, the biggest difference between the STO function and the brake is that the STO function can cut off the power source of the motor without turning off the power supply, while the brake is to hold the brake wheel or shaft under certain conditions (power off, no enable state). The safe torque off module 84 enables users to reliably cut off the motor power without cutting off the power supply of the driver, so that the system can be restarted faster after reaching a safe state.
[0074] The emergency stop button 81 and the changeover switch 82 are electrically connected to the power module 40 through a wire harness to take power from the power module 40 through the wire harness. In the event of an emergency in the elevator, such as an accident or maintenance, pressing the emergency stop button 81 connects the line in the control circuit to the power off, and the elevator stops immediately, achieving protection.
[0075] The changeover switch 82 is connected to the elevator safety circuit through a wire harness to realize the conversion of different working states of the elevator.
[0076] It should be noted that the elevator control driving device provided by the application is arranged in three layers along the direction perpendicular to the mounting plate 20. The first layer located outside the heat dissipation air duct 11 and mounted on the front surface 21 of the mounting plate 20 includes the main control board 51, the PG card 52, the car accidental movement protection module 83, the emergency stop button 81 and the change-over switch 82. The second layer located inside the heat dissipation air duct 11 and spaced from the back surface of the mounting plate 20 includes the drive board 31, the drive control board 33, the safety torque cancellation module 84, the capacitor board 341 and the rectifier bridge 342. The first heat dissipation assembly 61 and the second heat dissipation assembly 62 are located inside the heat dissipation air duct 11 and away from the first layer. In detail, the drive module 30 and the power module 40 mainly involve the strong current part and the devices have large loss, and are arranged inside the heat dissipation air duct 11 to achieve the heat dissipation of the devices with large loss. The control module 50 and the parts such as the car accidental movement protection module 83, the emergency stop button 81 and the change-over switch 82 mainly involve the weak current and the devices have relatively small loss, and the emergency stop button 81 and the change-over switch 82 need to be operated, and are arranged on the front surface 21 of the mounting plate 20 and located outside the heat dissipation air duct 11, so as to facilitate the operation and reduce the influence of the heat dissipated by the power module 40 and the drive module 30 on the devices such as the control module 50.
[0077] It should be noted that the elevator control driving device provided by the application integrates the rectification, inversion, elevator control, UCMP, integrated power supply, elevator change-over and emergency stop switch functions, has the full set of functions of the elevator driving control, and arranges the devices in three layers along the direction perpendicular to the mounting plate 20, so as to effectively reduce the volume of the control cabinet, greatly improve the space utilization, reduce the length of the connecting cables between the circuit boards, and reduce the working hours and cost required for production wiring and wiring. Moreover, it is beneficial to layer-by-layer disassembly and maintenance, and reduces the difficulty of disassembly and maintenance.
