Description

Technical Field

[0001] This utility model belongs to the field of brushless motor driver technology, and particularly relates to a high-efficiency DC brushless motor driver for ultra-low speed operation. Background Technology

[0002] An ultra-low-speed high-efficiency brushless DC motor driver is a drive device specifically designed to enable stable operation of brushless DC motors in the ultra-low speed range. The basic function of a brushless DC motor driver is to convert DC power into three-phase AC power to drive the motor. For the requirement of ultra-low-speed operation, the driver needs to be specially designed to ensure that the motor can still maintain smooth and efficient operation at low speeds. This usually involves precise adjustment of the motor commutation control and fine control of the PWM (pulse width modulation) signal.

[0003] Traditional high-efficiency brushless DC motor drivers operating at ultra-low speeds use screws to secure the housing. After prolonged use, when internal electronic components fail and require repair, users must use a screwdriver or wrench to remove each screw, following the markings on the driver housing, to access the internal components. This screw-based system prevents users from quickly disassembling the driver housing for repair, reducing maintenance efficiency. Therefore, we propose a high-efficiency brushless DC motor driver for ultra-low speed operation. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency DC brushless motor driver for ultra-low speed operation, so as to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a high-efficiency brushless DC motor driver for ultra-low speed operation, comprising:

[0006] A high-efficiency brushless DC motor driver and a first fixing block, wherein the first fixing block is fixedly connected to one side of the high-efficiency brushless DC motor driver, and a sealing plate is rotatably connected to the first fixing block;

[0007] A fixing assembly, located on a high-efficiency brushless DC motor driver, is used to fix the sealing plate.

[0008] The first slide groove is formed on the top surface of the high-efficiency DC brushless motor driver. A sliding frame is slidably connected inside the first slide groove. A sealing ring is fixedly connected to the top surface of the sliding frame, and two third fixing blocks are fixedly connected to the bottom surface of the sliding frame.

[0009] Two second slide grooves are formed on the inner wall of the first slide groove. Two sliders are slidably connected in the second slide groove. A bidirectional threaded rod is threaded between the two sliders and is located in the second slide groove and rotatably connected to the second slide groove. Multiple transmission rods are rotatably connected between the sliders and the two first slide grooves respectively.

[0010] A drive assembly, located within a high-efficiency brushless DC motor driver, is used to drive two bidirectional threaded rods to rotate.

[0011] Based on the above structure, the first fixed block and sealing plate ensure that the sealing plate can rotate on the first fixed block. When the sealing plate rotates to the appropriate position, the inner cavity of the high-efficiency brushless DC motor driver is exposed to the outside, facilitating user maintenance of the internal electronic components of the high-efficiency brushless DC motor driver. The fixed assembly ensures that the user can fix the sealing plate to the top surface of the high-efficiency brushless DC motor driver. The first slide groove, sliding frame, and sealing ring ensure that the sliding frame can move along the first slide groove to drive the sealing ring. The third fixed block, second slide groove, slider, and transmission rod ensure that the two slides... The blocks can move within the second slide groove. When the two sliders move, they can each drive the third fixed block to move up and down via two transmission rods. When the two third fixed blocks move up and down, they can also drive the sealing ring to move up and down via the sliding frame, causing the sealing ring to press against the bottom surface of the sealing plate, preventing external moisture from entering the high-efficiency DC brushless motor driver. The bidirectional threaded rod ensures that when it rotates, the two sliders can move closer or further apart due to the action of the thread. The drive assembly ensures that the user can drive the two bidirectional threaded rods to rotate via the drive assembly.

[0012] In the above technical solution, the fixing component further includes:

[0013] The second fixing block is fixedly connected to the other side of the high-efficiency brushless DC motor driver;

[0014] A rotating rod is rotatably connected to a second fixed block. The rotating rod is internally threaded with a one-way threaded rod. The bottom end of the one-way threaded rod is fixedly connected to a pressing block, and the bottom surface of the pressing block is in close contact with the top surface of the sealing plate.

[0015] This technical solution ensures that users can quickly release the sealing plate or quickly fix the sealing plate in place.

[0016] In the above technical solution, the extrusion block is further made of rubber.

[0017] In this technical solution, it is ensured that when the extrusion block is in close contact with the top surface of the sealing plate, there will be no excessive extrusion that could damage the top surface of the sealing plate.

[0018] In the above technical solution, the driving component further includes:

[0019] Two gear slots are formed inside the high-efficiency brushless DC motor driver and are connected to two second slides. Two first bevel gears are rotatably connected in the two gear slots, and one end of each of the two first bevel gears passes through the inner wall of the two gear slots and extends into the two second slides and is fixed to one end of each of the two bidirectional threaded rods. A handle is fixedly connected to one of the first bevel gears, and one end of the handle passes through the inner wall of one of the gear slots and extends to the outside and is rotatably connected to the high-efficiency brushless DC motor driver. Two second bevel gears are meshed on one side of each of the two first bevel gears, and the two second bevel gears are located in the two gear slots and are rotatably connected to the inner wall of each of the two gear slots.

[0020] A through slot is formed inside the high-efficiency DC brushless motor driver and communicates with two gear slots. A connecting rod is rotatably connected inside the through slot, and both ends of the connecting rod extend into the two gear slots and are fixed to the two second bevel gears respectively.

[0021] In this technical solution, it is ensured that external moisture cannot enter the inner cavity of the high-efficiency brushless DC motor driver through the gap between the high-efficiency brushless DC motor driver and the sealing plate.

[0022] In the above technical solution, one end of the first bevel gear is rotatably connected to the second sliding groove.

[0023] In this technical solution, it is ensured that one end of the first bevel gear can rotate normally within the second slide groove.

[0024] In the above technical solution, furthermore, the two ends of the connecting rod are rotatably connected to two gear slots respectively.

[0025] In this technical solution, it is ensured that both ends of the connecting rod can rotate normally within the two gear slots respectively.

[0026] In the above technical solution, furthermore, the two threads on the bidirectional threaded rod have opposite directions of rotation.

[0027] In this technical solution, it is ensured that when the bidirectional threaded rod rotates, the two sliders can be brought closer to each other or moved away from each other by the action of the two sections of threads on the bidirectional threaded rod with opposite directions of rotation.

[0028] The beneficial effects of this utility model are:

[0029] 1. This ultra-low-speed high-efficiency brushless DC motor driver, through the setting of a first fixed block and a sealing plate, ensures that the sealing plate can rotate on the first fixed block. When the sealing plate rotates to the appropriate position, the inner cavity of the high-efficiency brushless DC motor driver will be exposed to the outside, which facilitates the user to repair the electronic components inside the high-efficiency brushless DC motor driver. Through the setting of the fixing component, the user can ensure that the sealing plate can be fixed to the top surface of the high-efficiency brushless DC motor driver through the fixing component. This solves the problem that the screw fixing method makes it impossible for the user to quickly disassemble the housing of the ultra-low-speed high-efficiency brushless DC motor driver to repair the internal electronic components, thus reducing the maintenance efficiency.

[0030] 2. This ultra-low-speed high-efficiency brushless DC motor driver, through the setting of a first sliding groove, a sliding frame, and a sealing ring, ensures that the sliding frame can move along the first sliding groove to drive the sealing ring to move. Through the setting of a third fixed block, a second sliding groove, a slider, and a transmission rod, it ensures that the two sliders can move within the second sliding groove. When the two sliders move, they can drive the third fixed block to move up and down through the two transmission rods respectively. When the two third fixed blocks move up and down, they can drive the sealing ring to move up and down through the sliding frame, allowing the sliding frame to press the sealing ring against the bottom surface of the sealing plate, preventing external moisture from entering the high-efficiency brushless DC motor driver. Through the setting of a bidirectional threaded rod, it is ensured that when the bidirectional threaded rod rotates, the two sliders can be brought closer or further apart by the action of the bidirectional threaded rod. Through the setting of a drive assembly, it is ensured that the user can drive the two bidirectional threaded rods to rotate through the drive assembly. Attached Figure Description

[0044] Example 1:

[0045] Please see Figure 1 - Figure 6 As shown, this embodiment provides a high-efficiency brushless DC motor driver for ultra-low speed operation, including:

[0046] A high-efficiency brushless DC motor driver 1 and a first fixing block 2 are fixedly connected to one side of the high-efficiency brushless DC motor driver 1, and a sealing plate 3 is rotatably connected to the first fixing block 2.

[0047] A fixing assembly is located on the high-efficiency DC brushless motor driver 1 and is used to fix the sealing plate 3.

[0048] The first slide groove 5 is opened on the top surface of the high-efficiency DC brushless motor driver 1. A sliding frame 6 is slidably connected inside the first slide groove 5. A sealing ring 7 is fixedly connected to the top surface of the sliding frame 6. Two third fixing blocks 8 are fixedly connected to the bottom surface of the sliding frame 6.

[0049] Two second slide grooves 9 are formed on the inner wall of the first slide groove 5. Two sliders 10 are slidably connected in the second slide groove 9. A bidirectional threaded rod 12 is threaded between the two sliders 10 and is located in the second slide groove 9 and rotatably connected to the second slide groove 9. Multiple transmission rods 11 are rotatably connected between the multiple sliders 10 and the two first slide grooves 5 respectively.

[0050] The drive assembly is located inside the high-efficiency DC brushless motor driver 1 and is used to drive the two bidirectional threaded rods 12 to rotate.

[0051] Example 2:

[0052] This embodiment provides a high-efficiency brushless DC motor driver for ultra-low speed operation. In addition to the technical solutions described in the above embodiments, it also has the following technical features, including a fixed component:

[0053] The second fixing block 4 is fixedly connected to the other side of the high-efficiency DC brushless motor driver 1.

[0054] Rotating rod 13 is rotatably connected to the second fixed block 4. A one-way threaded rod 14 is internally threaded to the rotating rod 13. A pressing block 15 is fixedly connected to the bottom end of the one-way threaded rod 14, and the bottom surface of the pressing block 15 is in close contact with the top surface of the sealing plate 3.

[0055] When a user needs to repair the electronic components inside the high-efficiency brushless DC motor driver 1, the user manually rotates the one-way threaded rod 14, causing it to move upwards under the action of the rotating rod 13. This causes the one-way threaded rod 14 to move the pressing block 15 upwards. When the pressing block 15 moves to the appropriate position, the user manually rotates the rotating rod 13. When the rotating rod 13 reaches the appropriate position, the user manually rotates the sealing plate 3, causing it to rotate on the first fixed block 2. When the sealing plate 3 reaches the appropriate position, the inner cavity of the high-efficiency brushless DC motor driver 1 is exposed to the outside. The user can then repair the electronic components inside the high-efficiency brushless DC motor driver 1. After the repair is completed... Then, the user manually rotates the sealing plate 3 in the opposite direction, causing it to rotate in the opposite direction on the first fixing block 2. When the sealing plate 3 rotates to the appropriate position, it seals the inner cavity of the high-efficiency DC brushless motor driver 1. Subsequently, the user manually rotates the rotating rod 13 in the opposite direction. When the rotating rod 13 rotates to the appropriate position, the user manually rotates the one-way threaded rod 14 in the opposite direction, causing it to move downward under the action of the thread of the rotating rod 13. This causes the one-way threaded rod 14 to drive the pressing block 15 downward, making the pressing block 15 press tightly against the top surface of the sealing plate 3, thus fixing the sealing plate 3 to the top surface of the high-efficiency DC brushless motor driver 1. This ensures that the user can quickly release or quickly fix the sealing plate 3.

[0056] Example 3:

[0057] This embodiment provides a high-efficiency DC brushless motor driver for ultra-low speed operation. In addition to the technical solutions of the above embodiments, it also has the following technical features: the extrusion block 15 is made of rubber.

[0058] Specifically, it ensures that when the extrusion block 15 is in close contact with the top surface of the sealing plate 3, there will be no excessive extrusion that could damage the top surface of the sealing plate 3.

[0061] Two gear slots 16 are formed inside the high-efficiency DC brushless motor driver 1 and are connected to two second slides 9. Two first bevel gears 17 are rotatably connected in the two gear slots 16 respectively, and one end of each of the two first bevel gears 17 passes through the inner wall of the two gear slots 16 and extends into the two second slides 9 and is fixed to one end of each of the two bidirectional threaded rods 12. A handle 18 is fixedly connected to one of the first bevel gears 17, and one end of the handle 18 passes through the inner wall of one of the gear slots 16 and extends to the outside and is rotatably connected to the high-efficiency DC brushless motor driver 1. Two second bevel gears 19 are meshed on one side of each of the two first bevel gears 17, and the two second bevel gears 19 are located in the two gear slots 16 respectively and are rotatably connected to the inner wall of each of the two gear slots 16.

[0062] The through slot 20 is formed inside the high-efficiency DC brushless motor driver 1 and is connected to two gear slots 16. A connecting rod 21 is rotatably connected inside the through slot 20, and both ends of the connecting rod 21 extend into the two gear slots 16 respectively and are fixed to the two second bevel gears 19 respectively.

[0063] When the sealing plate 3 is fixed to the top surface of the high-efficiency DC brushless motor driver 1, the user rotates the handle 18 by hand, causing the handle 18 to drive one of the first bevel gears 17 to rotate in one of the gear slots 16. This causes one of the first bevel gears 17 to drive one of the second bevel gears 19 to rotate in one of the gear slots 16. When one of the second bevel gears 19 rotates, it drives the other second bevel gear 19 to rotate via the connecting rod 21. When the other second bevel gear 19 rotates, it drives the other first bevel gear 17 to rotate in the other gear slot 16. When both first bevel gears 17 rotate, they will drive two... The bidirectional threaded rod 12 rotates within the two second sliding grooves 9. When the two bidirectional threaded rods 12 rotate, multiple sliders 10 are respectively acted upon by the threads of the two bidirectional threaded rods 12, causing the corresponding two sliders 10 to move closer to each other. When the multiple sliders 10 move, they will drive the two third fixed blocks 8 to move through the multiple transmission rods 11, causing the two third fixed blocks 8 to move upward. When the two third fixed blocks 8 move upward, they will drive the sealing ring 7 to move upward through the sliding frame 6, causing the sealing ring 7 to be tightly pressed against the bottom surface of the sealing plate 3, ensuring that external moisture cannot enter the inner cavity of the high-efficiency DC brushless motor driver 1 through the gap between the high-efficiency DC brushless motor driver 1 and the sealing plate 3.

[0069] Specifically, it is ensured that both ends of the connecting rod 21 can rotate normally within the two gear slots 16 respectively.

[0070] Example 7:

[0071] This embodiment provides a high-efficiency DC brushless motor driver for ultra-low speed operation. In addition to the technical solutions of the above embodiments, it also has the following technical features: the two threads on the bidirectional threaded rod 12 have opposite directions of rotation.

[0072] Specifically, it is ensured that when the bidirectional threaded rod 12 rotates, the two sliders 10 can be brought closer to or moved away from each other by the action of the two sections of threads on the bidirectional threaded rod 12 with opposite directions of rotation.

[0073] When a user needs to repair the electronic components inside the high-efficiency brushless DC motor driver 1, the user manually rotates the one-way threaded rod 14, causing it to move upwards under the action of the rotating rod 13. This causes the one-way threaded rod 14 to move the pressing block 15 upwards. When the pressing block 15 moves to the appropriate position, the user manually rotates the rotating rod 13. When the rotating rod 13 reaches the appropriate position, the user manually rotates the sealing plate 3, causing it to rotate on the first fixed block 2. When the sealing plate 3 reaches the appropriate position, the inner cavity of the high-efficiency brushless DC motor driver 1 is exposed to the outside. The user can then repair the electronic components inside the high-efficiency brushless DC motor driver 1. After the repair is completed... The user manually rotates the sealing plate 3 in the opposite direction, causing it to rotate in the opposite direction on the first fixed block 2. When the sealing plate 3 rotates to the appropriate position, it seals the inner cavity of the high-efficiency DC brushless motor driver 1. Then, the user manually rotates the rotating rod 13 in the opposite direction. When the rotating rod 13 rotates to the appropriate position, the user manually rotates the one-way threaded rod 14 in the opposite direction, causing it to move downward under the action of the thread of the rotating rod 13. This causes the one-way threaded rod 14 to drive the pressing block 15 downward, making the pressing block 15 press tightly against the top surface of the sealing plate 3, thus fixing the sealing plate 3 to the top surface of the high-efficiency DC brushless motor driver 1. This ensures that the user can quickly release the sealing plate 3 or quickly fix it.

[0074] After the sealing plate 3 is fixed on the top surface of the high-efficiency DC brushless motor driver 1, the user rotates the handle 18 by hand, causing the handle 18 to drive one of the first bevel gears 17 to rotate in one of the gear slots 16. This causes one of the first bevel gears 17 to drive one of the second bevel gears 19 to rotate in one of the gear slots 16. When one of the second bevel gears 19 rotates, it drives the other second bevel gear 19 to rotate via the connecting rod 21.

When both first bevel gears 17 rotate, they will respectively drive two bidirectional... The threaded rod 12 rotates within the two second sliding grooves 9. When the two bidirectional threaded rods 12 rotate, the multiple sliders 10 are respectively acted upon by the threads of the two bidirectional threaded rods 12, causing the corresponding two sliders 10 to move closer to each other. When the multiple sliders 10 move, the multiple sliders 10 will respectively drive the two third fixed blocks 8 to move through the multiple transmission rods 11, causing the two third fixed blocks 8 to move upward. When the two third fixed blocks 8 move upward, the two third fixed blocks 8 will drive the sealing ring 7 to move upward through the sliding frame 6, causing the sealing ring 7 to be tightly pressed against the bottom surface of the sealing plate 3, ensuring that external moisture cannot enter the inner cavity of the high-efficiency DC brushless motor driver 1 through the gap between the high-efficiency DC brushless motor driver 1 and the sealing plate 3.
