Description

Technical Field

[0001] This utility model belongs to the field of constant current controller technology, specifically a motor constant current controller. Background Technology

[0002] A motor constant current controller typically consists of sensors, control circuits, and a power output module. It monitors the motor's operating current in real time and compares it with a set constant current value. Based on the comparison result, it adjusts the output signal to ensure that the motor maintains a stable current during operation. A stable current can prevent the motor from burning out due to excessive current. When the motor load changes, the constant current controller can quickly adjust the output to keep the current within a safe range and extend the motor's service life.

[0003] Traditional motor constant current controllers typically have their electronic components installed inside the controller's housing before the top cover is fixed to it. When the internal electronic components fail, it's difficult to disassemble the controller housing, delaying repairs. Furthermore, the difficulty in disassembling the housing forces repair personnel to spend more time attempting to open the equipment, extending the downtime of the motor controlled by the controller and impacting the overall production system's efficiency. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a motor constant current controller, which solves the problem of the inconvenience of timely repair of a faulty motor constant current controller.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a motor constant current controller, including a motor constant current controller housing, a top cover on the top of the motor constant current controller housing, transmission mechanisms on both sides inside the motor constant current controller housing, a snap-fit ​​mechanism on one side of the transmission mechanism, and two sets of both the transmission mechanism and the snap-fit ​​mechanism;

[0006] Both sets of transmission mechanisms include a push plate, a moving block, a lifting block, and a limiting component. Each set of transmission mechanisms has two moving blocks, two lifting blocks, and two limiting components. The two sides of the bottom end of the push plate overlap with the opposite side of the two moving blocks. The side of the two moving blocks away from the push plate overlaps with one end of the two lifting blocks. One side of the two lifting blocks is connected to one side of the two limiting components.

[0007] Preferably, telescopic springs are fixedly connected to both sides of the bottom of the top cover, and fixing blocks are fixedly connected to both sides of the top of the motor constant current controller housing. The fixing blocks have grooves inside that are adapted to the telescopic springs, and plug-in blocks are fixedly connected to both ends of the bottom of the top cover.

[0008] Preferably, the inside of both ends of the motor constant current controller housing is provided with receiving grooves adapted to the transmission mechanism and the snap-fit ​​mechanism, and the inside of the push plate is provided with a plug-in groove adapted to the plug-in block.

[0009] Preferably, a support frame is slidably connected to the bottom surface of both moving blocks, and a first spring is fixedly connected inside the support frame. The bottom surface of the support frame is connected to the inner bottom wall of the motor constant current controller housing. A fixing plate is fixedly connected to one end of the first spring. The top surface of the fixing plate is connected to the bottom surface of the moving block, and the bottom surface of the fixing plate is slidably connected to the inner bottom of the motor constant current controller housing.

[0010] Preferably, the limiting component includes a connecting block, a second spring, and a slider. One side of the connecting block is slidably connected to the surface of one side of the lifting block, and the other side of the connecting block is fixedly connected to the inner wall of the motor constant current controller housing. The top end of the second spring is fixedly connected to the bottom surface of the connecting block, the bottom end of the second spring is fixedly connected to the top surface of the slider, and the slider is slidably connected to the inner wall of the motor constant current controller housing.

[0011] Preferably, both sets of the snap-fit ​​mechanism include a hanging rod and a snap-fit ​​rod. Each set of the snap-fit ​​mechanism has two hanging rods and two snap-fit ​​rods. The two hanging rods and two snap-fit ​​rods are snapped together. The top surface of the two hanging rods is connected to the bottom surface of the top cover. One end of the two snap-fit ​​rods overlaps with the bottom end of the two lifting blocks.

[0012] Preferably, an adjusting plate is fixedly connected to the bottom surface of both clamping rods. The adjusting plate is slidably connected to the inside of the motor constant current controller housing. A stabilizing block is elastically connected to one side of the adjusting plate via a third spring. The stabilizing block is connected to one side of the inside of the motor constant current controller housing. Limiting blocks are fixedly connected to the outer surfaces of both ends of the motor constant current controller housing. The limiting blocks are connected to the push plate via threaded rods. Threaded caps are threaded to both ends of the threaded rods.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention, through the cooperation of a transmission mechanism and a snap-fit ​​mechanism, facilitates the splicing of the top cover and the motor constant current controller housing. As the top cover descends, the push plate experiences downward pressure. The bottom sides of the push plate contact the moving blocks, pushing them to slide laterally. During this sliding process, the moving blocks push the lifting block downwards. When the lifting block descends, its bottom end engages with one end of the locking rod, pushing the locking rod towards the hanging rod. Releasing the top cover causes the telescopic spring to move the top cover upwards, firmly locking the hanging rod and locking rod together. Finally, by rotating the threaded rod, the threaded caps at both ends are tightened, fixing the push plate in its current position, thus completing the splicing of the top cover and the motor constant current controller housing. This allows for rapid disassembly of the device. When repairing the internal electronic components of the motor constant current controller, the top cover can be easily disassembled by reversing the operation. Compared to the difficulty of disassembly in traditional structures, this significantly saves repair time, improves repair efficiency, and reduces production losses caused by repair delays.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a motor constant current controller, including a motor constant current controller housing 1, a top cover 2 on the top of the motor constant current controller housing 1, a transmission mechanism 3 on both sides inside the motor constant current controller housing 1, a snap-fit ​​mechanism 4 on one side of the transmission mechanism 3, and two sets of both the transmission mechanism 3 and the snap-fit ​​mechanism 4.

[0023] Both sets of transmission mechanisms 3 include a push plate 31, a moving block 32, a lifting block 33, and a limiting component 34. The number of moving blocks 32, lifting blocks 33, and limiting components 34 in both sets of transmission mechanisms 3 are two. The two sides of the bottom end of the push plate 31 overlap with the opposite side of the two moving blocks 32. The side of the two moving blocks 32 away from the push plate 31 overlaps with one end of the two lifting blocks 33. And one side of the two lifting blocks 33 is connected to one side of the two limiting components 34.

[0024] The above scheme is adopted: the motor constant current controller housing 1 provides protection and support for the internal electronic components of the motor constant current controller, and at the same time accommodates the transmission mechanism 3, the snap-fit ​​mechanism 4 and other components. The top cover 2 cooperates with the motor constant current controller housing 1 to seal the top of the motor constant current controller housing 1, protect the internal electronic components, and prevent dust, moisture and other substances from entering. All electronic components and other parts in the motor constant current controller are installed inside the motor constant current controller housing 1.

[0025] like Figures 1 to 5 As shown, telescopic springs 21 are fixedly connected to both sides of the bottom of the top cover 2, and fixing blocks 22 are fixedly connected to both sides of the top of the motor constant current controller housing 1. The inside of the fixing blocks 22 is provided with grooves that are compatible with the telescopic springs 21. The two ends of the bottom of the top cover 2 are fixedly connected with plug-in blocks 23. The inside of the two ends of the motor constant current controller housing 1 is provided with receiving grooves that are compatible with the transmission mechanism 3 and the snap-fit ​​mechanism 4. The inside of the push plate 31 is provided with plug-in grooves that are compatible with the plug-in blocks 23. The bottom surfaces of the two moving blocks 32 are slidably connected with support frames 321. The inside of the support frame 321 is fixedly connected with a first spring 322. The bottom surface of the support frame 321 is connected to the inner bottom wall of the motor constant current controller housing 1. One end of the first spring 322 is fixedly connected with a fixing plate. The top surface of the fixing plate is connected to the bottom surface of the moving block 32, and the bottom surface of the fixing plate is slidably connected to the inner bottom of the motor constant current controller housing 1.

[0026] Using the above scheme: After the push plate 31 is subjected to the pressure of the top cover 2, it transmits the force to the moving block 32. The moving block 32 moves to both sides under the action of the push plate 31, pushing the lifting block 33 to rise. At the same time, with the cooperation of the support frame 321, the first spring 322 and the fixing plate, the resetting after movement is achieved.

[0027] like Figures 1 to 5 As shown, the limiting component 34 includes a connecting block 341, a second spring 342, and a slider 343. One side of the connecting block 341 is slidably connected to the surface of one side of the lifting block 33, and the other side of the connecting block 341 is fixedly connected to the inner wall of the motor constant current controller housing 1. The top end of the second spring 342 is fixedly connected to the bottom surface of the connecting block 341, and the bottom end of the second spring 342 is fixedly connected to the top surface of the slider 343. The slider 343 is slidably connected to the inner wall of the motor constant current controller housing 1. Both sets of locking mechanisms 4 include hanging rods 41 and locking rods 42. Each set of locking mechanisms 4 has two hanging rods 41 and two locking rods 42. The two locking rods 42 are interlocked, and the top surfaces of the two hanging rods 41 are connected to the bottom surface of the top cover 2. One end of each locking rod 42 is connected to the bottom end of the two lifting blocks 33. The bottom surfaces of the two locking rods 42 are fixedly connected to the adjusting plate 421. The adjusting plate 421 is slidably connected to the inside of the motor constant current controller housing 1. One side of the adjusting plate 421 is elastically connected to the stabilizing block 423 through the third spring 422. The stabilizing block 423 is connected to one side of the inside of the motor constant current controller housing 1. The outer surfaces of both ends of the motor constant current controller housing 1 are fixedly connected to the limiting block 5. The limiting block 5 is connected to the push plate 31 through the threaded rod. Both ends of the threaded rod are threadedly connected to the threaded cap.

[0028] The above scheme is adopted: the hanging rod 41 is fixed at the bottom of the top cover 2 and cooperates with the locking rod 42 to realize the locking of the top cover 2 and the motor constant current controller housing 1. The locking rod 42 is locked with the hanging rod 41 under the push of the lifting block 33, fixing the top cover 2 on the motor constant current controller housing 1. The adjusting plate 421, the third spring 422 and the stabilizing block 423 on the bottom surface of the locking rod 42 cooperate to realize the movement and reset of the locking rod 42 in the locking and unlocking states.

[0029] The working principle and usage process of this utility model are as follows: When it is necessary to connect the top cover 2 and the motor constant current controller housing 1, align the insertion block 23 at the bottom of the top cover 2 with the insertion slot on the push plate 31 at the top of the motor constant current controller housing 1, and slowly lower the top cover 2. During the descent of the top cover 2, the telescopic springs 21 on both sides of its bottom enter the grooves inside the fixing blocks 22 on both sides of the top of the motor constant current controller housing 1. The descent of the top cover 2 causes the push plate 31 to be subjected to downward pressure, and the bottom sides of the push plate 31 contact the moving block 32 and... Push the two moving blocks 32 to slide to both sides. During the sliding process, the moving blocks 32 push the lifting block 33 to move downward. When the lifting block 33 descends, its bottom end overlaps with one end of the locking rod 42, pushing the locking rod 42 to move towards the hanging rod 41. Release the top cover 2. The telescopic spring 21 will drive the top cover 2 to move upward, so that the hanging rod 41 and the locking rod 42 are firmly locked. Finally, by rotating the threaded rod, the thread caps at both ends of the threaded rod are tightened, and the push plate 31 is fixed in the current position, completing the splicing of the top cover 2 and the motor constant current controller housing 1.

[0030] When it is necessary to disassemble the motor constant current controller housing 1 and the top cover 2, first, press down on the top cover 2, loosen the threaded caps at both ends of the threaded rod, release the fixation of the push plate 31, the push plate 31 moves upward, and when the push plate 31 rises, its bottom end separates from the moving block 32. Under the action of the first spring 322, the moving block 32 slides towards the middle. When the moving block 32 slides towards the middle, it no longer pushes the lifting block 33. The lifting block 33 rises under the action of the second spring 342. The rise of the lifting block 33 causes its bottom end to separate from the locking rod 42. Under the action of the third spring 422, the locking rod 42 moves away from the hanging rod 41, releasing the locking state of the hanging rod 41 and the locking rod 42. At this time, the top cover 2 can be easily lifted up to complete the disassembly of the top cover 2 and the motor constant current controller housing 1.
