Description

Technical Field

[0001] This invention relates to the field of motors, specifically to a heat dissipation structure for a motor end cover. Background Technology

[0002] Energy-saving motors are high-performance power devices made by combining high-efficiency magnetic materials with optimized electromagnetic design. Their structural design and material selection are systematically improved to achieve high efficiency and energy saving. Energy-saving motors can significantly improve overall operating efficiency while ensuring stable rated output power, effectively reducing energy loss and wasted energy during operation, and possessing outstanding energy-saving, consumption-reducing, and environmentally friendly advantages. To prevent overheating and excessive temperature rise during continuous operation and to ensure operational stability and safety, the motor's end cover is usually integrated with or equipped with a dedicated heat dissipation structure to dissipate internal heat in a timely manner through active or passive cooling methods.

[0003] However, most existing motor end cap heat dissipation structures employ a single heat dissipation mode, failing to achieve rational heat dissipation based on the actual operating conditions of the energy-saving motor and the external environment. This leads to excessive heat dissipation and low temperatures in low-speed or low-temperature environments. Prolonged operation at low temperatures accelerates the wear of internal components, significantly reducing the lifespan of the energy-saving motor. Therefore, we propose a motor end cap airflow-guiding heat dissipation structure. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a motor end cover heat dissipation structure.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a motor end cover heat dissipation structure, comprising a motor and an end cover fixedly mounted on the motor. The end cover has multiple annular medium channels hollowed out inside, with the centers of the multiple annular medium channels aligned with the center of the end cover. The diameters of the multiple annular medium channels decrease sequentially from the outside to the inside. Flow pipes are fixedly mounted through both sides of the end cover. Multiple connecting holes are opened through the outer surfaces of the opposite ends of the two flow pipes, and these connecting holes are respectively connected to the multiple annular medium channels. Control rods are slidably mounted through the opposite ends of the two flow pipes. Flow control pistons are fixedly mounted at the opposite ends of the two control rods. The flow control pistons are slidably mounted inside the flow pipes, and are offset from the connecting holes. Hand-held control components are mounted on the two flow pipes, and these hand-held control components are connected to the two control rods.

[0006] Preferably, the lower end of one of the flow tubes is fixedly connected to a discharge tube, and the lower end of the other flow tube is fixedly connected to an injection tube.

[0007] Preferably, a sealing piston is coaxially fixedly mounted on the outer surface of the control rod, and the sealing piston is slidably mounted inside the flow tube on the side away from the flow control piston.

[0008] Preferably, the hand-held control component includes two lifting plates slidably mounted on the outer surfaces of the two flow tubes. An H-shaped control frame is rotatably mounted on the lower end of each of the two lifting plates. The two H-shaped control frames are symmetrically arranged. The ends of the two H-shaped control frames are rotatably connected to the opposite ends of two control rods, respectively. A hand-held frame is fixedly mounted between the upper ends of the two lifting plates.

[0009] Preferably, a seat ring is fixedly sleeved on the outer surface of the flow tube, and a vertical hook seat extends from the upper end of the seat ring. Guide grooves are provided at both the front and rear ends of the vertical hook seat, and guide claws are fixedly installed at both the front and rear ends of the lifting plate. The ends of the guide claws are slidably installed inside the guide grooves.

[0010] Preferably, a first toothed plate is elastically installed on one side of the inside of the carrying frame, and a second toothed plate is elastically installed on the other side of the inside of the carrying frame. A central shaft is fixedly installed at the center of the inside of the carrying frame, and a gear is coaxially rotatably installed on the outer surface of the central shaft. The first toothed plate meshes with the rear part of the gear, and the second toothed plate meshes with the front part of the gear. A piston locking hook is fixedly installed at the lower end of both the first and second toothed plates. Two first movable holes are symmetrically opened at the lower end of the carrying frame, and the piston locking hooks pass through the inside of the first movable holes. Multiple hook grooves are linearly arrayed on the side of the hook seat, and the end of the piston locking hook is inserted into the inside of one of the hook grooves.

[0011] Preferably, a main handle is fixedly installed at the upper middle part of the carrying frame, a second movable hole is opened through the upper end of the carrying frame near the main handle, a secondary handle is provided on the side of the main handle, the secondary handle passes through the interior of the second movable hole, and a connecting block is fixedly installed at the lower end of the secondary handle, the end of the connecting block is fixed to the first toothed plate.

[0012] Preferably, T-shaped slides extend from the middle of the first toothed plate and the middle of the second toothed plate. Slide seats are slidably mounted on the outer surfaces of the two T-shaped slides. The slide seats are fixed to the inner wall of the handle frame. Spring seats are fixedly mounted on the opposite sides of the two slide seats. Locking springs are fixedly mounted on the sides of the two spring seats. The end of one locking spring is fixed to the first toothed plate, and the end of the other locking spring is fixed to the second toothed plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Through multiple annular medium flow channels with diameters decreasing from the outside to the inside, the moving control rod can drive the flow control piston to move, thereby controlling the number of annular medium flow channels opened, changing the contact area between the cooling medium and the end cover, and thus controlling the heat dissipation of the end cover. This allows the end cover to achieve rational heat dissipation based on the actual operating state of the motor and the external environment. For example, when the motor is at low speed or in a low temperature environment, the heat dissipation can be reduced to avoid the motor from becoming cold, thereby improving the service life of the energy-saving motor.

[0015] 2. By gripping the main handle and the auxiliary handle, moving the auxiliary handle toward the main handle will cause the first and second gear plates to move in opposite directions using the gears. This will cause the two piston hooks to disengage from the hook slots on the hook base. Then, pulling the main handle and the auxiliary handle upwards will raise the carrying frame and the lifting frame plate, which will then move the H-shaped control frame to push the two control levers to move. This will cause the two flow control pistons to move in opposite directions, controlling the number of openings in the annular medium flow channel. After releasing the auxiliary handle, the first and second gear plates will return to their original positions under the force of the locking spring. This will cause the two piston hooks to simultaneously engage in the other hook slot on the hook base, thus fixing the adjusted flow control pistons synchronously. This completes the adjustment process. The entire process only requires gripping the main handle and the auxiliary handle and pulling to control the number of openings in the annular medium flow channel. The operation is simple and convenient, effectively facilitating use and control. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] This invention provides a technical solution: such as Figure 1 - Figure 9The diagram illustrates a motor end cover heat dissipation structure, comprising a motor 1 and an end cover 2 fixedly mounted on the motor 1. The end cover 2 has multiple annular medium channels 19 hollowed out, which serve to supply cooling medium flow. The centers of the multiple annular medium channels 19 are aligned with the center of the end cover 2, and the diameters of the multiple annular medium channels 19 decrease sequentially from the outside to the inside, allowing the channels to evenly cover the end cover 2. Flow pipes 4 are fixedly mounted through both sides of the end cover 2. Multiple connecting holes 31 are formed through the outer surfaces of the opposite ends of the two flow pipes 4, each connecting to one of the multiple annular medium channels 19. The connecting holes 31 connect the flow pipes 4 and the annular medium channels 19. Control rods 12 are slidably mounted through the opposite ends of the two flow pipes 4, and flow control pistons 18 are fixedly mounted on the opposite ends of the two control rods 12 to control the flow. Rod 12 serves to adjust the position of the flow control piston 18. The flow control piston 18 is slidably installed inside the flow pipe 4, and is offset from the connecting hole 31. The flow control piston 18 can control the number of openings of the annular medium flow channel 19. Hand-held control components are installed on the two flow pipes 4, and the hand-held control components are connected to the two control rods 12. Through multiple annular medium flow channels 19 with diameters decreasing from the outside to the inside, the moving control rods 12 can drive the flow control piston 18 to move, thereby controlling the number of openings of the annular medium flow channels 19, changing the contact area between the cooling medium and the end cover 2, and thus controlling the heat dissipation of the end cover 2. This allows the end cover 2 to achieve rational heat dissipation according to the actual operating state of the motor 1 and the external environment. For example, when the motor 1 is at low speed or in a low temperature environment, the heat dissipation can be reduced to avoid the motor 1 from becoming cold, thereby improving the service life of the energy-saving motor 1.

[0028] One of the flow pipes 4 is fixedly connected to a discharge pipe 7 at its lower end, which serves to discharge the cooling medium. The other flow pipe 4 is fixedly connected to an injection pipe 8 at its lower end, which serves to inject the cooling medium.

[0029] A sealing piston 27 is coaxially fixedly mounted on the outer surface of the control rod 12. The sealing piston 27 is located away from the flow control piston 18. The sealing piston 27 can prevent the cooling medium from flowing out between the control rod 12 and the flow pipe 4. The sealing piston 27 is slidably mounted inside the flow pipe 4.

[0030] The portable control unit includes two lifting plates 10 slidably mounted on the outer surfaces of the two flow pipes 4. H-shaped control frames 11 are rotatably mounted on the lower ends of the two lifting plates 10. The lifting plates 10 drive the H-shaped control frames 11 to move. The two H-shaped control frames 11 are symmetrically arranged. The ends of the two H-shaped control frames 11 are rotatably connected to the opposite ends of the two control rods 12. The H-shaped control frames 11 push the control rods 12 to move. A carrying frame 3 is fixedly mounted between the upper ends of the two lifting plates 10. The carrying frame 3 allows the two lifting plates 10 to move synchronously. The carrying frame 3 and the lifting plates 10 move upward, thereby driving the H-shaped control frames 11 to move, which in turn drives the two control rods 12 to move, thereby driving the two flow control pistons 18 to move in opposite directions, so as to control the number of openings of the annular medium flow channel 19.

[0031] A seat ring 32 is fixedly sleeved on the outer surface of the flow pipe 4. A hook seat 23 extends from the upper end of the seat ring 32. The seat ring 32 serves to fix the hook seat 23. Guide grooves 24 are provided at both the front and rear ends of the hook seat 23. Guide claws 26 are fixedly installed at both the front and rear ends of the lifting plate 10. The cooperation between the guide grooves 24 and the guide claws 26 serves to guide the lifting plate 10. The end of the guide claw 26 is slidably installed inside the guide groove 24.

[0032] A first gear plate 13 is elastically installed on one side of the interior of the carrying frame 3, and a second gear plate 29 is elastically installed on the other side of the interior of the carrying frame 3. A central shaft 21 is fixedly installed at the center of the interior of the carrying frame 3. A gear 22 is coaxially mounted on the outer surface of the central shaft 21, which serves to support the gear 22. The first gear plate 13 meshes with the rear part of the gear 22, and the second gear plate 29 meshes with the front part of the gear 22. The gear 22 causes the second gear plate 29 and the first gear plate 13 to move in opposite directions. Piston locks are fixedly installed at the lower ends of both the first gear plate 13 and the second gear plate 29. The lower end of the hook 9 and the handle 3 has two symmetrically arranged first movable holes 20. The first movable holes 20 serve to ensure that the movement of the piston locking hook 9 is not obstructed. The piston locking hook 9 passes through the inside of the first movable hole 20. The side of the upright hook seat 23 has multiple hook grooves 25 arranged in a linear array. The hook grooves 25 can cooperate with the piston locking hook 9 to lock the flow control piston 18. The end of the piston locking hook 9 is inserted into the inside of one of the hook grooves 25. The gear 22 is used to make the first tooth plate 13 and the second tooth plate 29 move in opposite directions, thereby driving the two piston locking hooks 9 to disengage from the hook grooves 25 on the upright hook seat 23 respectively.

[0033] A main handle 5 is fixedly installed at the upper center of the carrying frame 3, facilitating lifting. A second movable hole 30 is provided at the upper end of the carrying frame 3 near the main handle 5. A secondary handle 6 is located to the side of the main handle 5. The second movable hole 30 ensures the normal movement of the secondary handle 6, which passes through the second movable hole 30. A connecting block 28 is fixedly installed at the lower end of the secondary handle 6, with its end fixed to the first gear plate 13. The connecting block 28 secures the secondary handle 6 and the first gear plate 13 together. By gripping the main handle 5 and the secondary handle 6, the secondary handle 6 moves towards the main handle 5, causing the first gear plate 13 and the second gear plate 29 to move in opposite directions via the gear 22. This, in turn, drives the two piston hooks 9 to... The hook detaches from the groove 25 on the hook seat 23, and then the main handle 5 and the auxiliary handle 6 are pulled upwards to move the carrying frame 3 and the lifting plate 10 upwards. This causes the H-shaped control frame 11 to move, which in turn moves the two control levers 12, thereby causing the two flow control pistons 18 to move in opposite directions to control the number of openings of the annular medium flow channel 19. Then, the auxiliary handle 6 is released, and the first tooth plate 13 and the second tooth plate 29 are reset under the elastic force of the locking spring 15. This causes the two piston locking hooks 9 to simultaneously engage in the other groove 25 on the hook seat 23, thereby fixing the two adjusted flow control pistons 18 synchronously. This completes the adjustment. The process only requires holding the main handle 5 and the auxiliary handle 6 and pulling to achieve the purpose of controlling the number of openings of the annular medium flow channel 19. The operation is simple and convenient for use and control.

[0034] T-shaped slide bars 16 extend from the middle of the first toothed plate 13 and the middle of the second toothed plate 29. Slide seats 14 are slidably installed on the outer surfaces of the two T-shaped slide bars 16. The cooperation between the T-shaped slide bars 16 and the slide seats 14 serves to guide the first toothed plate 13 and the second toothed plate 29. The slide seats 14 are fixed to the inner wall of the handle 3. Spring seats 17 are fixedly installed on the opposite sides of the two slide seats 14. Locking springs 15 are fixedly installed on the sides of the two spring seats 17. The spring seats 17 serve to support the locking springs 15. The end of one locking spring 15 is fixed to the first toothed plate 13, and the end of the other locking spring 15 is fixed to the second toothed plate 29. The locking springs 15 can reset the first toothed plate 13 and the second toothed plate 29, so that the piston locking hook 9 can be inserted into the hook groove 25 on the hook seat 23 to lock the two flow control pistons 18.

[0035] In use, the cooling medium enters the flow pipe 4 from the injection pipe 8 and flows into the annular medium flow channel 19 inside the end cover 2. It then enters the flow pipe 4 on the other side and finally exits from the discharge pipe 7, thus dissipating heat from the energy-saving motor 1. Simultaneously, depending on the actual operating state of the energy-saving motor 1 and the external environment, the main handle 5 and the auxiliary handle 6 can be gripped, causing the auxiliary handle 6 to move towards the main handle 5. This, in turn, uses gear 22 to cause the first gear plate 13 and the second gear plate 29 to move in opposite directions, thereby disengaging the two piston hooks 9 from the hook grooves 25 on the hook seat 23. Then, by pulling the main handle 5 and the auxiliary handle 6 upwards, the carrying frame 3 and the carrying plate 10 can be moved upwards, thereby moving the H-shaped control frame 11 to push the two control levers 12. The movement causes the two flow control pistons 18 to move in opposite directions, thereby controlling the number of openings in the annular medium flow channel 19. Then, the gripping handle 6 is released, causing the first tooth plate 13 and the second tooth plate 29 to reset under the elastic force of the locking spring 15. This causes the two piston locking hooks 9 to simultaneously engage in another hook groove 25 on the hook seat 23, thus fixing the adjusted two flow control pistons 18 synchronously. This controls the number of openings in the annular medium flow channel 19, changes the contact area between the cooling medium and the end cover 2, and thus controls the heat dissipation of the end cover 2. This allows the end cover 2 to achieve reasonable heat dissipation based on the actual operating state of the motor 1 and the external environment. For example, when the motor 1 is at low speed or in a low temperature environment, the heat dissipation can be reduced to avoid the motor 1 from becoming cold, thereby improving the service life of the energy-saving motor 1.
