Description

Technical Field

[0001] This invention relates to elevator systems, and particularly to an integrated door operator control unit. Background Technology

[0002] In elevator systems, the drive and control of the car door opening and closing are crucial. Currently, the motor and controller that drive the car door opening and closing are usually installed separately. This requires reserving installation space for the motor and controller in the elevator system's spatial layout, and the controller and motor need to be connected, matched, and debugged during the elevator system construction. This is not conducive to space layout and has relatively low practicality.

[0003] Currently, integrating the motor and controller into a single gantry crane drive and control unit reduces the complexity of gantry crane system installation. However, the resulting integrated gantry crane drive and control unit is relatively large and still requires significant space. Summary of the Invention

[0004] The purpose of this invention is to provide a small-sized integrated door operator control unit.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A door operator control unit, comprising:

[0007] The housing includes a housing, a support frame connected to the housing, and a cover connected to the housing. The support frame is disposed between the housing and the cover and is configured as a box-shaped structure with an opening facing the side of the housing. The area enclosed by the support frame and the housing is the motor area, and the area enclosed by the cover, the housing, and the support frame is the control area.

[0008] A drive motor is housed within the motor area and connected to the support frame. The drive motor includes a motor shaft that can be controllably rotated along a central axis, and the motor shaft passes through the housing.

[0009] An electronic control board is housed within the control area and electrically connected to the drive motor. The electronic control board includes a board body and a component assembly. The board body is disposed between the support frame and the cover. The component assembly is connected to the side of the board body near the support frame, and the board body is attached to the outer wall of the support frame.

[0010] Optionally, the receiving box has a plurality of first connection holes, the support frame has a plurality of second connection holes, and the body of the electronic control board has a plurality of third connection holes corresponding one-to-one with the first connection holes. Some of the first connection holes correspond to the second connection holes respectively and are connected to the corresponding second connection holes and the third connection holes through a plurality of connectors. Each first connection hole is connected to the corresponding third connection hole through the connector.

[0011] Optionally, the drive motor further includes a stator and a rotor. The stator is constructed in an annular shape and connected to the support frame. The annular rotor is sleeved inside the stator and connected to the motor shaft. The ends of the rotor near the plate and away from the plate are rotatably connected to the support frame and the housing box respectively through bearings. The stator, the rotor, the motor shaft and the bearings are coaxially arranged. The rotor can be controlled to rotate under the drive of the stator, and drives the motor shaft to rotate.

[0012] Optionally, the drive motor further includes an insulating layer, with two insulating layers respectively disposed at the two ends of the stator near the plate and away from the plate, and the stator includes an electromagnet and the rotor includes a permanent magnet.

[0013] Optionally, the component group includes an electromagnetic compatibility module, a rectifier filter, an inverter module, a main control module, and a Hall element. The electromagnetic compatibility module is electrically connected to the rectifier filter, the inverter module is electrically connected to the rectifier filter and the main control module, and the Hall element is electrically connected to the main control module.

[0014] Optionally, the accommodating box is provided with a heat dissipation control area, which is constructed in the shape of a groove and has a plurality of raised heat dissipation fins.

[0015] Optionally, the door operator control unit further includes a heat-conducting plate, which abuts against the inner wall of the control heat dissipation area and the rectifier filter, and / or the heat-conducting plate abuts against the inner wall of the control heat dissipation area and the inverter module.

[0016] Optionally, the control board further includes an input component, which is disposed on the side of the board body near the cover, and the cover has a portion cut out corresponding to the input component.

[0017] Optionally, the accommodating box and the box cover are detachably connected by a snap-fit ​​structure.

[0018] Optionally, the door operator drive and control integrated machine further includes a synchronous pulley connected to the motor shaft, the synchronous pulley being disposed outside the housing box.

[0019] The beneficial effects of this invention are as follows: by setting a support frame to fix the drive motor, the electronic control board and the drive motor can be stacked in the thickness direction. By staggering the component groups on the electronic control board with the support frame and the drive motor, the internal space density of the housing is increased, resulting in a smaller overall size of the door operator drive control integrated machine, which is easier to install.

[0020] Furthermore, connecting the housing box, support frame, and electrical control board simultaneously with a set of connectors helps to increase the spatial layout density, thereby saving space and reducing the size of the door operator drive and control integrated machine.

[0021] Furthermore, the stator is fixed and the rotor is supported by the support frame, which facilitates the fixing of the drive motor and the rotation of the motor shaft.

[0022] Furthermore, by setting an insulating layer, the electromagnetic influence of the electromagnet on the control board can be reduced, which helps to reduce the risk of control board failure.

[0023] Furthermore, by installing an electromagnetic compatibility module within the control board, the risk of malfunction caused by the magnetic field of the drive motor is reduced.

[0024] Furthermore, heat dissipation efficiency is improved by incorporating heat-conducting plates and heat dissipation zones. The heat dissipation zones are constructed with an overall recessed structure, which helps to improve space utilization.

[0025] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Please see Figure 1The door operator control unit protected by this utility model application includes a housing 1, a drive motor 2, and an electronic control board 3. The housing 1 includes a housing 11, a support frame 12 connected to the housing 11, and a cover 13 connected to the housing 11. The support frame 12 is disposed between the housing 11 and the cover 13, forming a box-shaped structure with an opening facing the side of the housing 11. The area enclosed by the support frame 12 and the housing 11 is the motor area, and the area enclosed by the cover 13, the housing 11, and the support frame 12 is the control area. The drive motor 2 is housed within the motor area and connected to the support frame 12. The drive motor 2 includes a motor shaft 23 that can be controllably rotated along a central axis, and the motor shaft 23 passes through the housing 11. The control board 3 is housed within the control area and electrically connected to the drive motor 2. The control board 3 includes a board body 31 and a component assembly. The board body 31 is positioned between the support frame 12 and the cover 13. The component assembly is connected to the side of the board body 31 near the support frame 12, and the board body 31 is attached to the outer wall of the support frame 12. By staggering the arrangement of the drive motor 2 and the control board 3, the space utilization within the housing 1 is improved, and the size of the integrated door operator drive and control unit is reduced.

[0035] Please refer to the following examples for details.

[0036] Example 1:

[0037] Please see Figure 1 The door operator control unit shown in a preferred embodiment of this application includes a housing 1, a drive motor 2, and an electronic control board 3. The drive motor 2 and the electronic control board 3 are housed within the housing 1, and the drive motor 2 is electrically connected to the electronic control board 3 to drive the automatic door to open and close.

[0038] Please see Figure 1 and Figure 2The housing 1 includes a receiving box 11, a support frame 12, and a lid 13. The receiving box 11 is made of aluminum alloy with good thermal conductivity and is constructed as a rectangular box-like structure with a single-sided opening. Protruding female buckles 111 are provided on the outer walls of its two opposite sides. The lid 13 is constructed as a box-like structure that fits into the single-sided opening of the receiving box 11 and is provided with a female buckle 131 extending towards the receiving box 11 and fitting into the female buckle 111. The receiving box 11 and the lid 13 are detachably connected by a snap-fit ​​structure formed by the female buckle 111 and the female buckle 131, thus forming a closed box-like structure. The support frame 12 is disposed between the receiving box 11 and the lid 13 and is constructed as a circular box-like structure with a single-sided opening. The surface opposite the opening is a rotating surface 121, and the side connected to the rotating surface 121 is a fixed surface 124. A circular rotating hole 122 is formed at the center of the rotating surface 121, penetrating the rotating surface 121, and multiple hollow areas are provided around the rotating hole 122. The diameter of the support frame 12 is matched with the housing box 11. A cylindrical fitting part 112 is formed inside the housing box 11, which is connected to the housing box 11 and structurally matched with the support frame 12. A through hole is provided on the housing box 11 corresponding to the center of the fitting part 112. The support frame 12 covers the fitting part 112, and its internal space is the motor area for accommodating the drive motor 2. The area enclosed by the other parts inside the housing box 11, the outer wall of the support frame 12, and the box cover 13 is the control area for accommodating the electronic control board 3. Multiple mounting holes 116 facing different directions are provided on the outer wall of the housing box 11 to facilitate the installation and fixation of the door machine drive and control integrated machine.

[0039] The housing 11 contains multiple hollow pillars 113. The inner wall of each hollow pillar 113 has a threaded structure, and the diameter of the end near the cover 13 is smaller, creating a stepped structure on the outer wall of the end. Some hollow pillars 113 are located outside and adjacent to the mating part 112. The edge of the rotating surface 121 of the support frame 12 has multiple mounting rings 125 connected to the fixed surface 124. Each mounting ring 125 corresponds to a hollow pillar 113, and the diameter and thickness of the mounting ring 125 are matched to the stepped structure of the hollow pillar 113. The opening at the top of the hollow pillar 113 is a first connecting hole, the hole in the middle of the mounting ring 125 is a second connecting hole, and the control board 3 has third connecting holes that correspond one-to-one with the first connecting holes. Multiple screws are used as connectors to connect the first and third connecting holes, and each mounting ring 125 is clamped between the hollow column 113 and the control board 3, so that the support frame 12 is fixed to the housing box 11, and together with the housing box 11, they form the motor area, and the control board 3 abuts against the support frame 12.

[0040] The drive motor 2 is a permanent magnet synchronous motor, including a stator 21, a rotor 22, and a motor shaft 23. The stator 21 is constructed in a ring shape and includes multiple sets of electromagnets arranged circumferentially. Each electromagnet consists of an iron core and coil windings surrounding the iron core. The outer wall of the stator 21 is fixedly connected to the inner wall of the mating part 112 of the housing box 11 by adhesive bonding. The rotor 22 is also constructed in a ring shape and is fitted inside the stator 21. The rotor 22 includes permanent magnets disposed on the outer side of the rotor 22 and facing the stator 21. The two ends of the rotor 22 along the central axis are rotatably connected to the rotating surface 121 of the support frame 12 and the housing box 11 respectively by bearings 24. The motor shaft 23 is fitted inside the rotor 22, fixedly connected to the rotor 22, and coaxially arranged with the stator 21, rotor 22, and bearings 24. The motor shaft 23 passes through the through hole of the housing box 11 and rotates synchronously with the rotor 22. In this embodiment, both bearings 24 are ball bearings 24. The outer ring of one bearing 24 is fitted into the rotation hole 122 of the support frame 12 and is fixedly connected to the support frame 12, while the inner ring is fixedly connected to the rotor 22. The outer ring of the other bearing 24 is fixed to the housing 11, and the inner ring is fixed to the motor shaft 23.

[0041] The drive motor 2 also includes an insulating layer 25. In this embodiment, the insulating layer 25 is insulating paper, which is attached to both sides of the rotating surface 121 of the stator 21 near or away from the support frame 12, thereby reducing the electromagnetic interference of the stator 21 to the outside world.

[0042] Please see Figure 3 The control board 3 includes a board body 31 and a component assembly. The board body 31 is a flat plate structure with multiple through holes serving as third connection holes. The component assembly is connected to the side of the board body 31 near the support frame 12 and includes an electromagnetic compatibility module 321, a rectifier filter 322, an inverter module 323, a main control module 324, and a Hall element 325. The electromagnetic compatibility module 321 is located away from the drive motor 2 to suppress electromagnetic interference from the drive motor 2. The rectifier filter 322 is adjacent to and electrically connected to the electromagnetic compatibility module 321, converting AC power to DC power to provide a stable power supply to the inverter module 323 and the main control module 324. The inverter module 323 converts DC power to AC power, causing the magnetic field direction of the electromagnet of the drive motor 2 to change periodically, thus achieving continuous rotation of the rotor 22. The main control module 324 is used to process the input electrical signals and output them. The Hall element 325 is located corresponding to the drive motor 2 and is used to detect the operating status of the drive motor 2. It is electrically connected to the main control module 324.

[0043] Please see Figure 1 and Figure 2The door operator control unit in this embodiment also includes heat-conducting plates 4. Two heat-conducting plates 4 respectively contact the rectifier filter 322 and the inverter module 323, and both heat-conducting plates 4 also contact the housing 11, used to quickly conduct the heat generated by the rectifier filter 322 and the inverter module 323 to the housing 11, improving heat dissipation efficiency. Two control heat dissipation areas 114 are formed on the housing 11 at the positions where they contact the heat-conducting plates 4. The control heat dissipation areas 114 are constructed as rectangular grooves recessed towards the interior of the housing 11, with multiple parallel protrusions arranged within them, thereby increasing the heat dissipation area and accelerating heat dissipation. Because the control heat dissipation areas 114 are offset from the motor area, space utilization is improved, and the airtightness of the housing 1 is maintained, thus protecting the internal drive motor 2 and electronic control board 3. The portion of the outer wall of the housing 11 corresponding to the motor area is also constructed as a mesh-like uneven structure, thereby assisting in the heat dissipation of the drive motor 2.

[0044] The door operator control unit in this embodiment also includes an input component 33 and an input marker 312. The input component 33 is located on the side of the control board 31 near the cover 13 and is electrically connected to the main control module 324, and includes multiple buttons. The cover 13 has a cutout corresponding to the input component 33 to facilitate the input of commands by activating the input component 33. The input marker 312 is attached to the outer wall of the cover 13 and embedded in the cover 13, with its position corresponding to the input component 33. It is used to indicate the input content of each button in the input component 33 and helps to protect the input component 33 and other internal structures of the housing 1.

[0045] The door operator control unit in this embodiment also includes a synchronous pulley 5. The synchronous pulley is located outside the housing 1 and is fixedly connected to the motor shaft 23. By cooperating with the synchronous belt and another synchronous pulley 5, the synchronous opening and closing of the doors on both sides can be achieved.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
