Description

Technical Field

[0001] This invention relates to the field of motor technology, and in particular to a same-side power distribution motor. Background Technology

[0002] In fields such as industrial automation and smart homes, motors are often required to provide dual-axis power output to drive the two actuators of the equipment to work together. Existing co-directional dual-axis output motors mostly adopt a structural design of "dual stator + dual rotor + dual output shaft". The core of this design is to drive the two output shafts respectively through two independent stator-rotor units to achieve co-directional power output.

[0003] However, existing co-rotating dual-axis output motors have the following significant drawbacks:

[0004] First, the structure is complex and the size is large: the design of dual stators and dual rotors requires reserved installation space for two independent drive units, resulting in a larger overall radial diameter or axial length of the motor, making it difficult to adapt to space-constrained scenarios (such as small smart home devices and precision instruments); at the same time, the assembly of dual drive units requires ensuring the coaxiality of the two rotors and the magnetic field symmetry of the two stators, the assembly process is complex, and mechanical vibration and noise are easily caused by assembly deviations.

[0005] Second, the cost is high: dual stators and dual rotors require an additional set of iron cores, windings and supporting bearings, housings and other components, which significantly increases the cost of raw materials; and dual drive units require two independent control systems (such as drivers and encoders), which further increases hardware and R&D costs, making it difficult to scale up applications.

[0006] Third, the heat dissipation and noise reduction effects are not good: the heat generated during the operation of the dual stator-dual rotor is superimposed, and the heat dissipation structure of existing motors is mostly a single air duct design, which makes it easy for heat to accumulate inside the motor, affecting the insulation performance of the stator winding and the service life of components such as electromagnets; at the same time, the noise generated by the rotation of the dual rotors and the dual shaft transmission is not effectively isolated, resulting in high motor operating noise and affecting the user experience. Summary of the Invention

[0007] The purpose of this invention is to provide a same-side power distribution motor that uses a single stator-single rotor main structure and multiple clutches to achieve single or synchronous output of dual shafts. By setting a reverse drive mechanism, different directions of output of the dual shafts can be achieved. By using a speed change mechanism, different directions and different speeds of output of the second output shaft can be achieved. While achieving the functions of existing same-direction dual-shaft output motors, this invention solves the problems of complex structure, high cost, and large size of existing same-direction dual-shaft output motors (dual stator, dual rotor).

[0008] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0009] A same-side power distribution motor includes a main housing and a stator integrally formed by insert injection molding. A rotor is sleeved inside the stator, and a main shaft is fixed in the middle of the rotor. The two ends of the main shaft are rotatably connected to the bottom of the main housing and a secondary housing, respectively, via bearings. The secondary housing is fixedly connected to the main housing. The stator is electrically connected to a microcontroller, which is fixed inside the secondary housing. A drive disk is fixed to the end of the main shaft that extends into the secondary housing. The drive disk is connected to a first output shaft via a first clutch mechanism and to a second output shaft via a second clutch mechanism. The first output shaft is rotatably connected inside the second output shaft, and its end extends outside the second output shaft. The second output shaft is rotatably connected inside a top cover, and its end extends outside the top cover. The top cover is fixedly connected to the secondary housing.

[0010] With the above technical solution, the stator drives the rotor to rotate after being energized, the rotor drives the main shaft to rotate, and the main shaft drives the drive disc to rotate. When the first output shaft needs to output power, the first clutch mechanism connects the power transmission between the drive disc and the first output shaft, and the drive disc drives the first output shaft to rotate through the first clutch mechanism; when the second output shaft needs to output power, the second clutch mechanism connects the power output between the drive disc and the second output shaft, and the drive disc drives the second output shaft to rotate through the second clutch mechanism; at the same time, the second output shaft and the first output shaft can also output power simultaneously.

[0011] The present invention is further configured such that: the spindle is formed with an axially penetrating through hole;

[0012] The first clutch mechanism includes a push-pull rod inserted into a through hole. The upper end of the push-pull rod extending through the through hole is formed with a spline shaft. The upper half of the spline shaft is inserted into a second spline hole at the bottom of the first output shaft. The lower half of the spline shaft is located above a first spline hole in the middle of the drive disk. The spline shaft and the first spline hole are fitted together and can be inserted into the first spline hole. A first support ring is formed in the middle of the spline shaft. A compression spring is clamped between the first support ring and the drive disk.

[0013] The push-pull rod is rotatably connected to the support base through the lower extension end of the through hole. A first electromagnet is provided on the lower side of the support base. The support base is inserted into the guide hole of the lower cover. The first electromagnet is fixed at the bottom of the guide hole. The lower cover is fixed at the bottom of the main housing. When the first electromagnet is energized, it can attract the support base. The first electromagnet is electrically connected to the single-chip microcomputer.

[0014] When the first output shaft needs to output power, the microcontroller controls the first electromagnet to work. The first electromagnet generates an attractive force that moves the support base downward. The support base moves the push-pull rod downward, and the push-pull rod moves the spline shaft into the first spline hole. At this time, the drive disk and the first output shaft are connected through the spline shaft, and the drive disk drives the first output shaft to rotate through the spline shaft. When it is necessary to disconnect the power output of the first output shaft, the microcontroller controls the first electromagnet to close. The support base loses the attraction of the first electromagnet, and then, under the action of the compression spring, the first support ring moves the spline shaft upward. The spline shaft moves upward and disengages from the first spline hole, thereby cutting off the power transmission between the drive disk and the spline shaft.

[0015] The invention is further configured such that the lower end of the compression spring abuts against a thrust bearing, the thrust bearing being inserted into a groove in the drive disc. When the power output between the drive disc and the first output shaft is disconnected, the thrust bearing prevents relative rotation between the compression spring and the drive disc, thereby reducing the resistance of the drive disc.

[0016] The present invention is further configured such that a drive gear is formed on the outer wall of the drive disk;

[0017] The second clutch mechanism includes a long gear meshing with a drive gear and a driven disc fixedly connected coaxially to a second output shaft. A first external gear ring is formed on the driven disc, located above the long gear. The long gear can move upwards to mesh with the first external gear ring. A first guide shaft is fixed to the lower part of the long gear, and the first guide shaft is inserted into upper and lower first bearings. The inner diameter of the first bearings and the outer diameter of the first guide shaft are clearance-fitted. The upper first bearing is fixed to a support frame, which is fixedly connected to the sub-housing. The lower first bearing is inserted into and fixed to a first support platform at the bottom of the sub-housing. A second electromagnet is fixed to the first support platform, and a first magnetic ring is provided above the second electromagnet. The first magnetic ring is fixed to the bottom of a first drive ring, which is fixed to the middle of the first guide shaft. The second electromagnet is electrically connected to a microcontroller.

[0018] When the second output shaft is needed, the microcontroller controls the second electromagnet to operate. The second electromagnet drives the first magnetic ring to move upward. The first magnetic ring, through the first drive ring, drives the first guide shaft to move upward. The first guide shaft drives the long gear to move upward, and the long gear meshes with the first external gear ring. At this time, the power of the drive disc is transmitted to the long gear through the first external gear ring. The long gear drives the driven disc to rotate through the first external gear ring, and the driven disc drives the second output shaft to rotate. When the microcontroller controls the magnetic poles of the second electromagnet to change, the second electromagnet attracts the first magnetic ring to move downward, thereby driving the long gear to move downward, thus disconnecting the power output.

[0019] The present invention is further configured such that: the second output shaft is provided with a reverse drive mechanism;

[0020] The reverse drive mechanism includes a first internal gear ring formed on the driven disc, a second gear meshing with the drive gear, a third gear and a second guide shaft formed on the second gear and coaxially arranged therewith, the third gear being located below the first internal gear ring, and the third gear moving upwards can mesh with the first internal gear ring; the second guide shaft is inserted into the upper and lower second bearings, the inner diameter of the second bearings and the outer diameter of the second guide shaft being clearance-fitted, the upper second bearing being fixed on the support frame; the lower second bearing is inserted into and fixed on the second support platform at the bottom of the sub-housing; a third electromagnet is fixed on the second support platform, a second magnetic ring is provided above the third electromagnet, the second magnetic ring is fixed to the bottom of the second drive ring, the second drive ring is fixed to the middle of the second guide shaft, and the third electromagnet is electrically connected to the single-chip microcomputer.

[0021] The reverse drive mechanism has a similar structure and working principle to the second clutch mechanism, but it cannot be used simultaneously with the second clutch mechanism. The difference is that the reverse drive mechanism engages the internal gear ring of the driven disc, while the second clutch mechanism engages the external gear ring of the driven disc, thus achieving rotation in different directions.

[0022] When the second output shaft needs to output in reverse, the microcontroller controls the third electromagnet to operate. The third electromagnet drives the second magnetic ring to move upward. The second magnetic ring, through the second drive ring, drives the second guide shaft to move upward. The second guide shaft drives the second gear and the third gear to move upward, and the third gear meshes with the first internal gear ring. At this time, the power of the drive disc is transmitted to the second gear through the drive gear, and the second gear is transmitted to the first internal gear ring through the third gear. The first internal gear ring drives the driven disc to reverse, and the driven disc drives the second output shaft to output in reverse. When the microcontroller controls the magnetic poles of the third electromagnet to change, the third electromagnet attracts the second magnetic ring to move downward, thereby driving the third gear to move downward and disengage from the first internal gear ring, thus disconnecting the power output.

[0023] The present invention is further configured such that: the second output shaft is provided with a speed change mechanism;

[0024] The speed-changing mechanism includes a first intermediate gear meshing with a long gear, a second intermediate gear meshing with a second gear, a second external gear ring and a second internal gear ring formed on the driven disc; the first intermediate gear has a first speed-changing gear and a third guide shaft coaxially arranged therewith, the first speed-changing gear is located below the second external gear ring, and the first speed-changing gear can move upward to mesh with the second external gear ring, a third magnetic ring is fixed at the lower part of the first intermediate gear, and a fourth electromagnet is provided below the third magnetic ring; the second intermediate gear has a second speed-changing gear and a fourth guide shaft coaxially arranged therewith, the second speed-changing gear is located below the second internal gear ring, and the second speed-changing gear can move upward to mesh with the second internal gear ring, a fourth magnetic ring is fixed at the lower part of the second intermediate gear, and a fifth electromagnet is provided below the fourth magnetic ring, the fourth electromagnet and the fifth electromagnet are fixed on the support frame and are both electrically connected to the single-chip microcomputer; the third guide shaft and the fourth guide shaft respectively pass through corresponding third bearings, the third bearings are inserted into and fixed on the support frame, and the third bearings are clearance-fitted with the third guide shaft and the fourth guide shaft.

[0025] When the second output shaft needs to rotate slowly forward, the microcontroller controls the fifth electromagnet to work. The fifth electromagnet drives the fourth magnetic ring to move upward, which in turn drives the second intermediate gear to move upward. The second intermediate gear then drives the second gear shifter to move upward, and the gear shifter engages with the second internal gear ring. At this time, the power of the drive disc is transmitted to the driven disc sequentially through the second gear, the second intermediate gear, the second gear shifter, and the second internal gear ring. The driven disc drives the second output shaft to rotate slowly forward. When the microcontroller controls the fifth electromagnet to change its magnetic poles, the fifth electromagnet attracts the fourth magnetic ring to move downward, and the gear shifter disengages from the second internal gear ring, thus disconnecting the power output.

[0026] When the second output shaft needs to slowly reverse, the microcontroller controls the fourth electromagnet to work. The fourth electromagnet drives the third magnetic ring to move upward, which in turn drives the first intermediate gear to move upward. The first intermediate gear then drives the first gear shifter to move upward and mesh with the second outer gear ring. At this time, the power of the drive disc is transmitted to the driven disc in sequence through the long gear, the first intermediate gear, the first gear shifter, and the second outer gear ring. The driven disc drives the second output shaft to slowly reverse. When the microcontroller controls the fourth electromagnet to change its magnetic poles, the fourth electromagnet drives the third magnetic ring to move downward, and the first gear shifter disengages from the second outer gear ring, thereby disconnecting the power output.

[0027] The present invention is further configured such that: the sub-shell is formed with a drive cavity with an upper opening and an isolation cavity with a lower opening; the first clutch mechanism, the second clutch mechanism, the reverse drive mechanism and the speed change mechanism are placed in the drive cavity.

[0028] By placing various transmission mechanisms inside the drive cavity, most of the noise generated during transmission can be "confined" within the drive cavity; the noise transmitted from the drive cavity can be further reduced by the isolation wall, thereby reducing the noise during motor operation.

[0029] The present invention is further configured such that: the bottom of the driving cavity is formed with a plurality of first vent holes, the upper sidewall of the driving cavity is formed with a plurality of second vent holes connecting the driving cavity and the isolation cavity, and the lower sidewall of the isolation cavity is formed with a plurality of third vent holes.

[0030] An impeller is fixed in the middle of the main shaft, and the impeller is located above the rotor and below the sub-casing.

[0031] When the motor is working, the main shaft drives the impeller to rotate. The heat generated by the stator and rotor is transported upwards through the air gap and other parts, and then pumped into the drive chamber through the impeller and the first vent. If some water vapor enters the drive chamber from the first and second output shafts when the motor is working, the water vapor can be evaporated by heating the drive chamber. Then, the heat and hot air enter the isolation chamber through the second vent, and finally are discharged to the outside through the third vent. Because the impeller is constantly working, the heat in the drive chamber will not be too high, and it will not affect the normal use of components such as electromagnets.

[0032] The present invention is further configured such that an air inlet duct is formed on the lower cover;

[0033] The bottom of the main housing is formed with a fourth vent hole, which is located below the rotor.

[0034] The main shaft has a fifth vent hole formed in the middle, which communicates with the through hole. The fifth vent hole is located between the rotor and the impeller.

[0035] When the impeller rotates, a negative pressure is generated in the lower region of the impeller. Outside air enters the lower cover through the air inlet duct, and then the air entering the lower cover splits into two paths. One path enters between the stator and rotor through the fourth vent, and then moves upward along the air gap, where the air exchanges heat with and cools the stator, thus carrying away the heat generated by the stator upward. The other path enters the gap between the through hole and the push-pull rod, and then moves upward along the through hole and exits below the impeller through the fifth vent. The air here exchanges heat with and cools the main shaft and rotor, and the heat is conducted upward through the gap and discharged. By introducing ambient temperature air, the cooling effect of the motor can be further improved.

[0036] The invention is further configured such that a filter sponge is fixed inside the air inlet duct. The filter sponge filters the air entering the lower cover, preventing impurities and excessive moisture from entering.

[0037] The outstanding effects of this invention are:

[0038] Compared with the prior art, the present invention adopts a single stator-single rotor main structure and uses multiple clutches to achieve single or synchronous output of dual shafts; by setting a reverse drive mechanism, output of dual shafts in different directions can be achieved; by using a speed change mechanism, output of the second output shaft in different directions and at different speeds can be achieved; while achieving the functions of existing co-rotating dual-shaft output motors, it solves the problems of complex structure, high cost and large size of existing co-rotating dual-shaft output motors (dual stator, dual rotor);

[0039] By integrating a dual-layer structure of driving cavity and isolation cavity and a dual-channel heat dissipation system, the goal of improving noise reduction effect and heat dissipation performance is achieved.

[0040] By controlling each mechanism to operate independently using a microcontroller, flexible allocation of dual-axis power (independent start / stop, steering switching, and speed change output) is achieved, meeting the diverse needs of multiple scenarios. Attached Figure Description

[0054] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0055] The following is for reference Figures 1 to 5 The present invention will be described as follows:

[0056] A type of same-side power distribution motor, such as Figure 1 , Figure 2 As shown, the device includes a main housing 11 and a stator 12 integrally formed by insert injection molding. A rotor 13 is sleeved inside the stator 12. A main shaft 14 is fixed in the middle of the rotor 13. The two ends of the main shaft 14 are rotatably connected to the bottom of the main housing 11 and the secondary housing 16 respectively through bearings. The secondary housing 16 is fixedly connected to the main housing 11. The stator 12 is electrically connected to a microcontroller 18, which is fixed inside the secondary housing 16. A drive disk 2 is fixed to the end of the main shaft 14 that extends into the secondary housing 16. The drive disk 2 is connected to a first output shaft 4 through a first clutch mechanism 3 and a second output shaft 5 through a second clutch mechanism 6. The first output shaft 4 is rotatably connected inside the second output shaft 5, and its end extends outside the second output shaft 5. The second output shaft 5 is rotatably connected inside an upper cover 17, and its end extends outside the upper cover 17. The upper cover 17 is fixedly connected to the secondary housing 16.

[0057] like Figure 3 As shown, the main shaft 14 is formed with an axially penetrating through hole 141;

[0058] The first clutch mechanism 3 includes a push-pull rod 31 inserted into a through hole 141. A splined shaft 32 is formed at the upper end of the push-pull rod 31 extending through the through hole 141. The upper half of the splined shaft 32 is inserted into a second splined hole 41 at the bottom of the first output shaft 4. The lower half of the splined shaft 32 is located above a first splined hole 21 in the middle of the drive disk 2. The splined shaft 32 and the first splined hole 21 are fitted together and can be inserted into the first splined hole 21. A first support ring 33 is formed in the middle of the splined shaft 32. A compression spring 34 is held between the first support ring 33 and the drive disk 2. The lower end of the compression spring 34 abuts against a thrust bearing 37, which is inserted into a groove 22 in the drive disk 2. When the power output between the drive disk 2 and the first output shaft 4 is disconnected, the thrust bearing 37 prevents relative rotation between the compression spring 34 and the drive disk 2, thereby reducing the resistance of the drive disk 2.

[0059] like Figure 4 As shown, the push-pull rod 31 is rotatably connected to the support base 35 through the lower extension end of the through hole 141. A first electromagnet 36 is provided on the lower side of the support base 35. The support base 35 is inserted into the guide hole 151 of the lower cover 15. The first electromagnet 36 is fixed at the bottom of the guide hole 151. The lower cover 15 is fixed at the bottom of the main housing 11. When the first electromagnet 36 is energized, it can attract the support base 35. The first electromagnet 36 is electrically connected to the microcontroller 18.

[0060] like Figure 3 As shown, a drive gear 23 is formed on the outer wall of the drive disk 2;

[0061] The second clutch mechanism 6 includes a long gear 61 that meshes with the drive gear 23 and a driven disk 62 that is coaxially fixedly connected to the second output shaft 5. A first external gear ring 621 is formed on the driven disk 62. The first external gear ring 621 is located above the long gear 61. The long gear 61 can move upward to mesh with the first external gear ring 621. A first guide shaft 63 is fixed to the lower part of the long gear 61. The first guide shaft 63 is inserted into a first bearing 64 arranged vertically. The inner diameter of the first bearing 64 is perpendicular to the first guide shaft 64. The first bearing 64 on the upper side is fixed to the support frame 65, which is fixedly connected to the sub-housing 16, and the first bearing 64 on the lower side is inserted into and fixed to the first support 161 at the bottom of the sub-housing 16.

The first magnetic ring 67 is fixed to the bottom of the first drive ring 68, and the first drive ring 68 is fixed to the middle of the first guide shaft 63. The second electromagnet 66 is electrically connected to the microcontroller 18.

[0062] like Figure 5 As shown, the second output shaft 5 is equipped with a reverse drive mechanism 7;

[0063] The reverse drive mechanism 7 includes a first internal gear ring 622 formed on the driven disk 62, a second gear 71 meshing with the drive gear 23, a third gear 72 and a second guide shaft 73 formed on the second gear 71 and coaxially arranged therewith, the third gear 72 being located below the first internal gear ring 622, and the third gear 72 being able to mesh with the first internal gear ring 622 when moved upward; the second guide shaft 73 is inserted into the upper and lower second bearings 74, the inner diameter of the second bearings 74 being clearance-fitted with the outer diameter of the second guide shaft 73, the upper second bearing 74 being fixed on the support frame 65; the lower second bearing 74 being inserted into and fixed on the second base 162 at the bottom of the sub-housing 16; a third electromagnet 75 is fixed on the second base 162, a second magnetic ring 76 is provided above the third electromagnet 75, the second magnetic ring 76 is fixed to the bottom of the second drive ring 77, the second drive ring 77 is fixed to the middle of the second guide shaft 73, and the third electromagnet 75 is electrically connected to the microcontroller 18.

[0064] The reverse drive mechanism 7 has a similar structure and working principle to the second clutch mechanism 6, but cannot be used simultaneously with the second clutch mechanism 6. The difference is that the reverse drive mechanism 7 engages the internal gear ring of the driven disc 62, while the second clutch mechanism 6 engages the external gear ring of the driven disc 62, thereby achieving rotation in different directions.

[0065] like Figure 3 , Figure 5 As shown, the second output shaft 5 is equipped with a speed change mechanism 8;

[0066] The transmission mechanism 8 includes a first intermediate gear 81 meshing with a long gear 61, a second intermediate gear 82 meshing with a second gear 71, a second external gear ring 623 and a second internal gear ring 624 formed on the driven disc 62; the first intermediate gear 81 has a first transmission gear 83 and a third guide shaft 84 coaxially arranged therewith, the first transmission gear 83 is located below the second external gear ring 623, and the first transmission gear 83 can move upward to mesh with the second external gear ring 623, a third magnetic ring 85 is fixed to the lower part of the first intermediate gear 81, and a fourth electromagnet 86 is provided below the third magnetic ring 85; the second intermediate gear 82 has a second transmission gear 83 coaxially arranged therewith. The second gear 87 and the fourth guide shaft 88 are located below the second internal gear ring 624. The second gear 87 can move upward to mesh with the second internal gear ring 624. The lower part of the second intermediate gear 82 is fixed with a fourth magnetic ring 89. The lower part of the fourth magnetic ring 89 is provided with a fifth electromagnet 810. The fourth electromagnet 86 and the fifth electromagnet 810 are fixed on the support frame 65 and are both electrically connected to the microcontroller 18. The third guide shaft 84 and the fourth guide shaft 88 pass through the corresponding third bearing 811. The third bearing 811 is inserted and fixed on the support frame 65. The third bearing 811 is clearance-fitted with the third guide shaft 84 and the fourth guide shaft 88.

[0067] like Figure 2 As shown, the sub-shell 16 is formed with a drive cavity 163 with an upper opening and an isolation cavity 164 with a lower opening; the first clutch mechanism 3, the second clutch mechanism 6, the reverse drive mechanism 7 and the speed change mechanism 8 are placed in the drive cavity 163.

[0068] By setting various transmission mechanisms inside the drive cavity 163, most of the noise generated during transmission can be "confined" inside the drive cavity 163; the noise transmitted from the drive cavity 163 can be further reduced by the isolation wall, thereby reducing the noise when the motor is working.

[0069] like Figure 2 As shown, the bottom of the driving cavity 163 is formed with a plurality of first vent holes 165, the upper sidewall of the driving cavity 163 is formed with a plurality of second vent holes 166 connecting the driving cavity 163 and the isolation cavity 164, and the lower sidewall of the isolation cavity 164 is formed with a plurality of third vent holes 167.

[0070] An impeller 19 is fixed in the middle of the main shaft 14. The impeller 19 is located above the rotor 13 and below the secondary housing 16.

[0071] When the motor is working, the main shaft 14 drives the impeller 19 to rotate. The heat generated by the stator 12 and rotor 13 is transported upward through the air gap and other parts, and pumped into the drive chamber 163 through the impeller 19 and the first vent 165. If some water vapor enters the drive chamber 163 from the first output shaft 4 and the second output shaft 5 when the motor is working, the water vapor can be evaporated by heating the drive chamber 163. Then, the heat and hot air enter the isolation chamber 164 through the second vent 166, and finally are discharged to the outside through the third vent 167. Since the impeller 19 is working continuously, the heat in the drive chamber 163 will not be too high, and it will not affect the normal use of components such as electromagnets.

[0072] like Figure 2 As shown, an air inlet duct 152 is formed on the lower cover 15;

[0073] The bottom of the main housing 11 is formed with a fourth vent 111, which is located below the rotor 13.

[0074] The main shaft 14 has a fifth vent hole 142 formed in the middle, which communicates with the through hole 141. The fifth vent hole 142 is located between the rotor 13 and the impeller 19.

[0075] When the impeller 19 rotates, a negative pressure is generated in the lower region of the impeller 19. Outside air enters the lower cover 15 through the air inlet pipe 152. The air entering the lower cover 15 then splits into two paths. One path enters the space between the stator 12 and the rotor 13 through the fourth vent 111, and then moves upward along the air gap. The air exchanges heat with the stator 12, cooling it and carrying away the heat generated by the stator 12 upward. The other path enters the gap between the through hole 141 and the push-pull rod 31, then moves upward along the through hole 141 and is discharged below the impeller 19 through the fifth vent 142. The air exchanges heat with the main shaft 14 and the rotor 13, cooling them, and the heat is conducted upward through the gap and discharged. By introducing ambient temperature air, the cooling effect of the motor can be further improved.

[0076] A filter sponge 110 is fixed inside the air inlet duct 152. The filter sponge 110 can filter the air entering the lower cover 15 to prevent impurities and excessive moisture from entering.

[0077] Working principle

[0078] Main power source output: After the stator 12 is energized, it generates a magnetic field that drives the rotor 13 to rotate. The rotor 13 drives the main shaft 14 to rotate synchronously, and the main shaft 14 in turn drives the drive disk 2 to rotate, thus realizing the initial output of power.

[0079] The first output shaft 4 outputs: the microcontroller 18 controls the first electromagnet 36 to be energized, attracting the support base 35 to move down. The support base 35 drives the push-pull rod 31 to move down, and the push-pull rod 31 drives the spline shaft 32 to insert into the first spline hole 21 of the drive disk 2, so that the power of the drive disk 2 is transmitted to the first output shaft 4 through the spline shaft 32. When the power is off, the compression spring 34 pushes the spline shaft 32 to move up and reset, disengaging from the first spline hole 21 and cutting off the power.

[0080] The second output shaft 5 outputs in the forward direction: the microcontroller 18 controls the second electromagnet 66 to work, the second electromagnet 66 and the first magnetic ring 67 repel each other and drive the long gear 61 to move upward, meshing with the first external gear ring 621 of the driven disk 62, and the power of the driving disk 2 is transmitted to the second output shaft 5 through the driving gear 23, the long gear 61 and the first external gear ring 621; the microcontroller 18 controls the magnetic pole change of the second electromagnet 66, the second electromagnet 66 and the first magnetic ring 67 attract each other and drive the long gear 61 to move downward and reset, thereby cutting off the power.

[0081] The second output shaft 5 outputs in reverse: The microcontroller 18 controls the third electromagnet 75 to work. The third electromagnet 75 and the second magnetic ring 76 repel each other, pushing the second gear 71 to move upward, so that the third gear 72 meshes with the first internal gear ring 622. Through gear reversal, the power is transmitted through the second gear 71 → the third gear 72 → the driven disk 62, realizing the reverse rotation of the second output shaft 5; The microcontroller controls the third electromagnet 75 to change the magnetic poles. The third electromagnet 75 and the second magnetic ring 76 attract each other, driving the third gear 72 to move downward and reset, and the power is cut off.

[0082] Second output shaft 5 speed reduction output:

[0083] Slow forward rotation: The microcontroller 18 controls the fifth electromagnet 810 to work. The fifth electromagnet 810 and the fourth magnetic ring 89 repel each other, pushing the fourth magnetic ring 89 to move upward. The fourth magnetic ring 89 drives the second intermediate gear 82 to move upward. The second speed-changing gear 87 moves upward and meshes with the second internal gear ring 624. The power is transmitted through the second gear 71 → second intermediate gear 82 → second speed-changing gear 87 → second internal gear ring 624. The speed is reduced by the gear ratio, driving the driven plate 62 to rotate slowly forward. The microcontroller 18 controls the fifth electromagnet 810 to switch magnetic poles, and the power is cut off.

[0084] Slow Reverse Rotation: The microcontroller 18 controls the fourth electromagnet 86 to work. The fourth electromagnet 86 and the third magnetic ring 85 repel each other, pushing the third magnetic ring 85 to move upward, so that the first intermediate gear 81 drives the first speed-changing gear 83 to mesh with the second external gear ring 623. The power is transmitted through the long gear 61 → first intermediate gear 81 → first speed-changing gear 83 → second external gear ring 623. The speed is reduced by the gear ratio, which drives the driven plate 62 to slowly reverse. The microcontroller 18 controls the fourth electromagnet 86 to switch magnetic poles, and the power is cut off.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications assumed above should also be considered within the scope of protection of the present invention.
