Description

Technical Field

[0001] This invention relates to the field of motor heat dissipation technology, specifically to a servo motor with a heat dissipation structure. Background Technology

[0002] A servo motor is an actuator that can precisely control speed, angle, and position, receiving control signals and responding quickly. It has a built-in feedback device that provides real-time feedback on its operating status, correcting position and speed deviations to achieve high-precision motion control. Unlike ordinary motors, it features fast response, stable torque, and high positioning accuracy, and is widely used in automation equipment, robots, CNC machine tools, and other applications. It is often paired with a heat dissipation structure to ensure stable operation over extended periods, guaranteeing precise and reliable equipment movements.

[0003] When equipment operates continuously for extended periods, servo motors generate a significant amount of heat. Existing servo motors typically rely solely on natural body cooling or are equipped with fixed fans for heat dissipation. These fixed fan locations cover a limited area, easily leading to localized heat buildup and uneven heat dissipation. Prolonged exposure to high temperatures can cause internal components to age prematurely. Furthermore, relying solely on air cooling is insufficient to quickly dissipate the concentrated heat generated by the motor. In harsh environments, dust and debris can easily accumulate at the cooling points, further hindering heat dissipation and potentially causing the motor to overheat, burn out, and malfunction, significantly shortening its lifespan. Summary of the Invention

[0004] The present invention provides a servo motor with a heat dissipation structure to solve at least one of the problems mentioned in the background art.

[0005] To address the aforementioned technical problems, this invention discloses a servo motor with a heat dissipation structure, including a base plate, empty boxes on both sides of the base plate, a sliding plate on the side of the empty boxes that are close to each other, a metal plate mounted on the sliding plate, and the motor body mounted on the metal plate. An air outlet slot is formed on the side of the empty boxes that are close to each other, and a movable component is disposed within the empty boxes. Several fans are mounted on the movable component, with the fans' air outlets facing the air outlet slots. Several metal rods are mounted on the metal plate, and a coolant tank is disposed on the base plate, with the metal rods extending into the coolant tank. The movable fans expand the air-cooling heat dissipation range, effectively improving the problems of localized heat accumulation and uneven heat dissipation within the motor body. Simultaneously, the heat conduction of the metal rods, combined with the heat dissipation of the coolant tank, significantly improves the overall heat dissipation efficiency, quickly removing the operating heat of the motor body and preventing aging and burnout due to long-term high-temperature operation. This effectively improves the working stability of the motor body and greatly extends its service life.

[0006] The front of the empty box is fixed with the same drive box. The drive motor is fixedly installed on the inner wall of the front side of the drive box. The rear output end of the drive motor is fixedly connected to a rotating rod. A fan compartment is set on the rear side wall of the empty box. The rotating rod rotates and extends into the fan compartment. Several blades are fixedly installed at the rear end of the rotating rod. Power is provided independently by the drive motor to continuously assist the motor body in blowing air. Through the air guiding effect of the ventilation holes, the airflow acts on the surface of the motor body, effectively improving the problem of poor air circulation and heat accumulation near the motor, further improving the overall heat dissipation efficiency, and making the motor body run more stably for a long time.

[0007] The moving component includes a threaded rod that extends into the drive box. A driving pulley is fixedly mounted on the rotating rod, and a driven pulley is fixedly mounted on the threaded rod. A drive belt is wound around the driving pulley and the driven pulley. A moving plate is threadedly connected to the threaded rod. The moving plate is slidably connected to the upper and lower inner walls of the empty box. Several fixed blocks are fixedly mounted on the moving plate. A rotating rod passes through the fixed blocks. An adjusting block is fixedly connected to one end of the rotating rod. A fan is fixedly mounted on the adjusting block.

[0008] A traveling rod is rotatably mounted on the movable plate. A drive gear is fixedly mounted on the side of the traveling rod away from the motor body. A drive rack is fixedly mounted on the lower inner wall of the empty box, and the drive rack meshes with the drive gear. A turntable is fixedly mounted on the side of the traveling rod close to the motor body. An eccentric rod is fixedly mounted at the eccentric position of the turntable. A moving frame is fitted on the outer periphery of the eccentric rod. An L-shaped connecting rod is fixedly mounted on the moving frame. An adjusting rack is fixedly connected to the other end of the L-shaped connecting rod. An adjusting gear is fixedly mounted on the other end of the rotating rod, and the adjusting gear meshes with the adjusting rack. Using the power of the original drive motor, no additional power source is needed. The fan can move horizontally as a whole and also oscillate. The airflow coverage is larger, which can dissipate heat from multiple parts of the motor body, reduce local heat accumulation, and improve the heat dissipation effect. The equipment is less likely to overheat during long-term operation.

[0009] A pipe runs through the front of the coolant tank, and a circulation pipe runs through the rear of the coolant tank. U-shaped pipes are symmetrically connected through the pipes, and the other end of the U-shaped pipes is connected to the circulation pipe. Several cooling blocks are also installed inside the coolant tank. Several metal rods are fixedly installed on the lower surface of the metal plate. The metal rods slide through the sliding plate. Several positioning cylinders are installed through the upper side wall of the coolant tank. The metal rods and positioning cylinders are inserted and matched.

[0010] A rotating shaft with a propeller is installed inside the pipeline. The shaft rotates forward and extends into the drive box. A main drive wheel is fixed on the rotating rod, and a driven drive wheel is fixed on the rotating shaft. A drive belt is wound around the main and driven drive wheels. The heat generated by the motor body is first transferred to a metal plate, and then conducted from the metal plate to a series of metal rods. The metal rods extend into the coolant tank through positioning cylinders, directly transferring heat to the coolant. The cooling blocks inside the tank also assist in cooling, making the circulating coolant temperature lower and improving the heat absorption effect. The coolant is automatically circulated by the drive motor, eliminating the need for an additional pump. The structure is simple and cost-effective. The direct heat conduction through the metal rods, combined with circulating liquid cooling, results in fast heat absorption and stable heat dissipation, greatly improving the overall cooling effect of the motor.

[0011] Several elastic support rods are fixedly installed on the base plate. The upper end of the elastic support rods is fixedly connected to the sliding plate. The coolant tank is located in the center of the base plate. Sliding plates are provided on both the left and right sides of the coolant tank. Several elastic elements are fixedly installed on the side of the two sliding plates that are far apart from each other. A limit plate is fixedly installed on the other end of the elastic element. The limit plate is fixedly installed on the base plate. Several buffer components are also installed on the sliding plate.

[0012] The buffer assembly includes a hinge, a connecting rod hinged to the hinge, and a mounting block hinged to the other end of the connecting rod. The mounting block is fixedly installed on the lower surface of the sliding plate. A triangular block is fixedly installed at the lower end of the connecting rod. An elastic telescopic member is hinged to the triangular block. A fixing member is hinged to the other end of the elastic telescopic member. The fixing member is fixedly installed on the outer walls of both sides of the coolant tank. The fixing member is located on the upper side of the U-shaped tube.

[0013] The elastic telescopic component includes a cylindrical body. A square connector is fixedly installed at one end of the cylindrical body, and the square connector is hinged to the fixed component. A buffer component is fixedly installed on the inner wall of the cylindrical body. A sliding rod is fixedly installed at the other end of the buffer component. The sliding rod is slidably connected to the cylindrical body and extends out of the cylindrical body. A block-shaped connector is fixedly installed at the other end of the sliding rod, and the block-shaped connector is hinged to a triangular block. Through multiple sets of elastic structures, the vibration impact is offset in stages, effectively weakening the vibration generated by the operation of the equipment, reducing the shaking amplitude of the whole machine, and making the motor body run more smoothly.

[0014] Symmetrical through slots are provided on the sliding plate, and clamping plates are slidably arranged in the through slots. Several clamping strips are fixedly arranged on the side of the clamping plates that are close to each other. The upper end of the clamping plate is lower than the lower edge of the air outlet duct. The metal plate is located on the side of the clamping plates that are close to each other. Several clamping springs are also fixedly arranged on the side of the clamping plates that are close to each other. The other end of the clamping springs is fixedly connected to the through slot. The clamping plate is provided with an inclined surface, and the limiting plate is provided with a mating surface. The inclined surface and the mating surface slide together. The upper end of the clamping plate is lower than the lower edge of the air outlet duct, so it will not block the air outlet route of the air outlet duct 7. At the same time, the clamping strip with a strip structure contacts the motor body. The contact area is strip-shaped, which can reduce the obstruction of the cooling airflow by the clamping structure. When the motor body is installed, automatic clamping is achieved by the cooperation of the inclined surface and the mating surface. The disassembly and assembly of the motor body is relatively convenient. The strip-shaped clamping strip achieves reliable clamping and limiting while reducing interference with the air duct.

[0015] In summary, compared with the prior art, the present invention provides a servo motor with a heat dissipation structure, which has the following beneficial effects: The moving component drives a fan, which can change its blowing position and dissipate heat to different parts of the motor body through the air outlet, resulting in a wider heat dissipation coverage, improving the problems of localized heat accumulation and uneven heat dissipation, and enhancing the heat dissipation effect of air cooling; the heat generated by the motor body during operation is conducted through a metal plate to a metal rod, which extends into the coolant tank, transferring heat to the coolant, achieving liquid-cooled assisted heat conduction and cooling, compensating for the insufficient heat exchange capacity of single air cooling, and quickly removing the concentrated heat generated by the motor; the dual heat dissipation works together to effectively reduce the operating temperature of the motor body, slow down the aging rate of internal components, and extend the overall service life of the servo motor.

Detailed Implementation

[0018] 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.

[0019] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0021] Example 1: Embodiments of the present invention provide a servo motor with a heat dissipation structure, such as... Figures 1-11 As shown, the device includes a base plate 4, empty boxes 2 on both sides of the base plate 4, a sliding plate 5 on the side of the empty boxes 2 that are close to each other, a metal plate 27 mounted on the sliding plate 5, a motor body 3 mounted on the metal plate 27, an air outlet slot 7 on the side of the empty boxes 2 that are close to each other, a moving component inside the empty box 2, a number of fans 40 mounted on the moving component, the air outlet of the fans 40 facing the air outlet slot 7; a number of metal rods 19 mounted on the metal plate 27, a coolant tank 25 mounted on the base plate 4, and the metal rods 19 extending into the coolant tank 25.

[0022] The working principle and beneficial effects of the above technical solution are as follows: The motor body 3 continuously generates a large amount of heat. The heat is first conducted to the metal plate 27 at the bottom, and the metal plate 27 quickly disperses the heat. It is then transferred to the coolant tank 25 below through multiple metal rods 19. The coolant is used to quickly absorb the heat, achieving liquid cooling. At the same time, the moving components inside the empty box 2 drive the fan 40 to move, so that the fan 40 blows air back and forth to different positions of the motor body 3 through the air outlet 7 to dissipate heat, no longer limited to a single heat dissipation position. Through the dual heat dissipation method of air cooling and liquid cooling, the heat generated by the operation of the motor body 3 is continuously removed. The movable fan 40 expands the air-cooling range, effectively improving the problems of localized heat accumulation and uneven heat dissipation in the motor body 3. Simultaneously, the metal rod 19, combined with the coolant tank 25, significantly enhances overall heat dissipation efficiency, quickly removing the operating heat from the motor body 3. This prevents the motor body 3 from aging or burning out due to prolonged high-temperature operation, effectively improving the operational stability of the motor body 3 and greatly extending its service life.

[0023] Example 2: Based on the above embodiment 1, as follows Figures 1-2 As shown, the same drive box 1 is fixedly connected to the front side of the empty box 2. A drive motor 8 is fixedly installed on the inner wall of the front side of the drive box 1. A rotating rod 15 is fixedly connected to the rear output end of the drive motor 8. A fan compartment 12 is provided on the rear side wall of the empty box 2. The rotating rod 15 rotates and extends into the fan compartment 12. Several blades 18 are fixedly installed at the rear end of the rotating rod 15.

[0024] The fan compartment 12 has several ventilation holes (not shown in the figure) on the side facing the motor body 3. The working principle and beneficial effects of the above technical solution are as follows: the drive motor 8 inside the drive box 1 starts, driving the rotating rod 15 to rotate continuously. The rotating rod 15 further drives the blades 18 inside the fan compartment 12 to rotate at high speed. The rotation of the blades 18 generates airflow. The airflow blows directly onto the motor body 3 through the ventilation hole on the side of the fan compartment 12, providing airflow and heat dissipation to the motor body 3 and accelerating the airflow around the motor body 3.

[0025] The drive motor 8 provides independent power and continuously assists the airflow to the motor body 3. Through the airflow guiding effect of the ventilation holes, the airflow acts on the surface of the motor body 3, which effectively improves the problem of poor air circulation and heat accumulation near the motor, further improves the overall heat dissipation efficiency, and makes the motor body 3 more stable in long-term operation.

[0026] Example 3: Based on the above embodiments 1-2, such as Figure 1 , Figures 5-6 As shown, the moving component includes a threaded rod 6 that extends into the drive box 1. A drive pulley 13 is fixedly mounted on the rotating rod 15, and a driven pulley 14 is fixedly mounted on the threaded rod 6. A drive belt 11 is wound around the drive pulley 13 and the driven pulley 14. A moving plate 30 is threadedly connected to the threaded rod 6. The moving plate 30 is slidably connected to the upper and lower inner walls of the empty box 2. Several fixing blocks 26 are fixedly mounted on the moving plate 30. A rotating rod 38 passes through the fixing blocks 26. An adjusting block 39 is fixedly connected to one end of the rotating rod 38. A fan 40 is fixedly mounted on the adjusting block 39.

[0027] Preferably, a traveling rod 33 is rotatably and through the moving plate 30. A drive gear 32 is fixedly installed on the side of the traveling rod 33 away from the motor body 3. A drive rack 29 is fixedly installed on the lower inner wall of the empty box 2. The drive rack 29 is meshed with the drive gear 32. A turntable 28 is fixedly installed on the side of the traveling rod 33 close to the motor body 3. An eccentric rod 31 is fixedly installed at the eccentric position of the turntable 28. A moving frame 34 is fitted on the outer periphery of the eccentric rod 31. An L-shaped connecting rod 35 is fixedly installed on the moving frame 34. An adjusting rack 37 is fixedly connected to the other end of the L-shaped connecting rod 35. An adjusting gear 36 is fixedly installed at the other end of the rotating rod 38. The adjusting gear 36 is meshed with the adjusting rack 37.

[0028] The working principle and beneficial effects of the above technical solution are as follows: the drive motor 8 starts and drives the rotating rod 15 to rotate. The rotating rod 15 drives the driven pulley 14 to rotate through the driving pulley 13 and the drive belt 11. The driven pulley 14 drives the threaded rod 6 to rotate. The threaded rod 6 drives the moving plate 30 to slide back and forth along the inner wall of the empty box 2. The moving plate 30 moves together with the fixed block 26, the adjusting block 39 and the fan 40, thereby changing the blowing position of the fan 40. During the sliding of the movable plate 30, the drive gear 32 rolls along the drive rack 29, thereby causing the drive gear 32, the walking rod 33 and the turntable 28 to rotate together. The eccentric rod 31 on the turntable 28 drives the movable frame 34 to move up and down reciprocally. The movable frame 34 drives the L-shaped connecting rod 35 and the adjusting rack 37 to move up and down. The adjusting rack 37 drives the adjusting gear 36 to rotate back and forth, causing the rotating rod 38 and the adjusting block 39 to swing with the fan 40.

[0029] Powered by the existing drive motor 8, no additional power source is needed. The fan 40 can move horizontally as a whole and also oscillate, covering a wider area and dissipating heat from multiple locations on the motor body 3. This reduces local heat buildup, improves heat dissipation, and makes the equipment less prone to overheating during long-term operation.

[0030] Example 4: Based on the above embodiment 3, such as Figures 1-4 As shown, a pipe 23 is connected through the front side of the coolant tank 25, and a circulation pipe 21 is connected through the rear side of the coolant tank 25. U-shaped pipes 24 are symmetrically connected through the pipe 23, and the other end of the U-shaped pipe 24 is connected through the circulation pipe 21. Several cooling blocks 22 are also provided inside the coolant tank 25. Several metal rods 19 are fixedly provided on the lower surface of the metal plate 27. The metal rods 19 slide through the sliding plate 5. Several positioning cylinders 20 are installed through the upper side wall of the coolant tank 25. The metal rods 19 and the positioning cylinders 20 are inserted and matched.

[0031] Preferably, a rotating shaft 9 is provided inside the pipe 23, a propeller 17 is provided on the rotating shaft 9, the rotating shaft 9 rotates forward and extends into the drive box 1, a main drive wheel is fixedly provided on the rotating rod 15, a driven wheel 16 is fixedly provided on the rotating shaft 9, and a drive belt 10 is wound around the main drive wheel and the driven wheel 16.

[0032] The working principle and beneficial effects of the above technical solution are as follows: the drive motor 8 drives the rotating rod 15 to rotate, the rotating rod 15 drives the main drive wheel to rotate, the main drive wheel drives the drive wheel 16 to rotate through the transmission belt 10, thereby causing the rotating shaft 9 to rotate together. The rotating shaft 9 drives the propeller 17 inside the pipe 23 to rotate. The rotation of the propeller 17 generates thrust, which pushes the coolant to flow, so that the coolant can continuously circulate inside the coolant tank 25, pipe 23, U-shaped pipe 24 and circulation pipe 21, thereby realizing the circulation and heat dissipation of the coolant.

[0033] The heat generated by the motor body 3 is first transferred to the metal plate 27, and then conducted by the metal plate 27 to the metal rods 19. The metal rods 19 extend into the coolant tank 25 through the positioning cylinder 20, directly transferring the heat to the coolant. The cooling block 22 inside the tank can also assist in cooling, making the circulating coolant temperature lower and the heat absorption effect better.

[0034] The coolant is automatically circulated by the drive motor 8, eliminating the need for an additional pump. The structure is simple and cost-effective. Heat is directly conducted through the metal rod 19, and combined with the circulating liquid cooling, the heat absorption speed is fast and the heat dissipation is stable, which greatly improves the overall cooling effect of the motor.

[0035] In summary, a single drive motor 8 can simultaneously perform multiple tasks, including auxiliary air supply, fan 40 translation and oscillation, and coolant circulation pumping. This single power source can power multiple cooling mechanisms without requiring separate motors and drive components for air supply, fan 40 movement, and coolant circulation. The various cooling mechanisms work together in coordination, combining ordinary air cooling, fan oscillation, and circulating liquid cooling to form a comprehensive cooling system. This significantly reduces the number of parts in the machine, effectively lowers equipment production costs, and reduces the potential for malfunctions caused by multiple power sources, making the equipment more reliable.

[0036] Example 5: Based on the above embodiment 4, such as Figures 7-9 As shown, several elastic support rods 41 are fixedly installed on the base plate 4. The upper end of the elastic support rods 41 is fixedly connected to the sliding plate 5. The coolant tank 25 is located in the center of the base plate 4. Sliding plates 43 are provided on both the left and right sides of the coolant tank 25. Several elastic elements 46 are fixedly installed on the side of the two sliding plates 43 that are far apart from each other. A limit plate 42 is fixedly installed on the other end of the elastic element 46. The limit plate 42 is fixedly installed on the base plate 4. Several buffer components are also installed on the sliding plate 43.

[0037] Preferably, the buffer assembly includes a hinge 50, a connecting rod 45 hinged to the hinge 50, and a mounting block 44 hinged to the other end of the connecting rod 45. The mounting block 44 is fixedly installed on the lower surface of the sliding plate 5. A triangular block 49 is fixedly provided at the lower end of the connecting rod 45. An elastic telescopic member is hinged to the triangular block 49. A fixing member 47 is hinged to the other end of the elastic telescopic member. The fixing member 47 is fixedly provided on the outer walls of both sides of the coolant tank 25 and is located on the upper side of the U-shaped tube 24.

[0038] Preferably, the elastic telescopic component includes a cylindrical body 48, one end of which is fixedly provided with a square connector 51, which is hinged to a fixing member 47. A buffer member 52 is fixedly provided on the inner wall of the cylindrical body 48, and the other end of the buffer member 52 is fixedly provided with a sliding rod 53, which is slidably connected to the cylindrical body 48 and extends slidably out of the cylindrical body 48. The other end of the sliding rod 53 is fixedly provided with a block-shaped connector 54, which is hinged to a triangular block 49.

[0039] The working principle and beneficial effects of the above technical solution are as follows: After the motor body 3 is installed above the sliding plate 5, the metal rod 19 below the metal plate 27 will be precisely aligned and inserted into the positioning cylinder 20 of the coolant tank 25 to ensure that heat can be conducted normally. When the equipment vibrates during operation, the motor body 3 and the sliding plate 5 will have a slight downward displacement, and the sliding plate 5 will compress the elastic support rod 41 downward, completing the first layer of buffering.

[0040] As the sliding plate 5 presses down, it moves the mounting block 44 below it down as well, causing the connecting rod 45 to rotate. The connecting rod 45 pulls the sliding rod 53 via the triangular block 49. The sliding rod 53 retracts into the cylinder 48 and squeezes the buffer 52, achieving a second layer of buffering. The rotation of the connecting rod 45 also pushes the sliding plate 43 to move. The sliding plate 43 compresses the elastic element 46, further absorbing the impact brought by the downward pressure. Through multiple sets of elastic structures to offset the vibration impact in stages, the vibration generated by the operation of the equipment is effectively weakened, the vibration amplitude of the whole machine is reduced, and the motor body 3 runs more smoothly.

[0041] Example 6: Based on the above embodiment 5, such as Figures 7-8 , Figures 10-11As shown, the sliding plate 5 has symmetrical through slots 57, and a clamping plate 55 is slidably arranged in the through slot 57. Several clamping strips 56 are fixedly arranged on the side of the clamping plates 55 that are close to each other. The upper end of the clamping plate 55 is lower than the lower edge of the air outlet slot 7. The metal plate 27 is located on the side of the clamping plates 55 that are close to each other. Several clamping springs 60 are also fixedly arranged on the side of the clamping plates 55 that are close to each other. The other end of the clamping springs 60 is fixedly connected to the through slot 57. The clamping plate 55 is provided with an inclined surface 59, and the limiting plate 42 is provided with a mating surface 58. The inclined surface 59 and the mating surface 58 are slidably engaged.

[0042] The working principle and beneficial effects of the above technical solution are as follows: When the motor body 3 is installed, the motor body 3 descends under the action of gravity. The motor body 3 drives the sliding plate 5 to move downward synchronously, and the clamping plate 55 moves downward together with the sliding plate 5. During the downward movement of the clamping plate 55, the inclined surface 59 on it abuts against the mating surface 58 of the limiting plate 42. Under the guidance of the inclined surface, the clamping plates 55 on both sides move towards the middle, the clamping spring 60 is compressed, and the clamping bars 56 on both sides clamp the motor body 3, realizing automatic clamping and positioning of the motor body 3 without the need for additional locking components.

[0043] When disassembling the motor body 3, first push the two clamping bars 56 outward to move the clamping plate 55 outward, releasing the clamping action of the clamping bars 56 on the motor body 3. Then lift the motor body 3 upward, and the sliding plate 5 returns to its original position. The inclined surface 59 and the mating surface 58 no longer engage. The clamping spring 60 rebounds further, driving the two clamping plates 55 to continue to separate outward. The clamping bars 56 completely detach from the motor body 3, and the disassembly is completed.

[0044] The upper surface of the clamping plate 55 is lower than the lower edge of the air outlet slot 7, so it will not block the air outlet route of the air outlet slot 7; at the same time, the clamping bar 56 with a strip structure contacts the motor body 3, and the contact area is strip-shaped, which can reduce the obstruction of the cooling airflow by the clamping structure.

[0045] During the installation of the motor body 3, automatic clamping is achieved through the cooperation of the inclined surface 59 and the mating surface 58, making the assembly and disassembly of the motor body 3 relatively convenient. The strip-shaped clamping bar 56 achieves reliable clamping and limiting while reducing interference with the air duct.

[0046] During the installation of the motor body 3, the metal rod 19 can be inserted into place simultaneously by simply lowering the motor body 3. The buffer component enters the working state, and the motor body 3 is automatically clamped and positioned. The assembly action drives multiple structures to move together, taking into account heat conduction and docking, buffering and shock absorption, and clamping and fixing of the motor body 3. All components cooperate with each other, simplifying the installation operation of the whole machine and achieving better integration.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
