Description

Technical Field

[0001] The present invention relates to the technical field of motors, and particularly to an unmanned aerial vehicle (UAV) motor with heat dissipation and dust prevention functions. Background Art

[0002] The UAV motor is a key component that provides power for the UAV. Currently, the most widely used type of motor in UAVs is the brushless motor, which has the advantages of high efficiency, high power density, high reliability, and simple maintenance. By controlling the speed and rotation direction of the motor through an electronic speed controller, the flight attitude and actions of the UAV can be accurately controlled. Among them, the energy-saving motor is a motor designed to improve the energy utilization efficiency of the UAV and extend the flight time. Through an efficient heat dissipation structure or the use of materials with good heat dissipation performance, the heat generated during the operation of the motor can be dissipated in a timely manner, avoiding a decrease in motor performance or efficiency due to overheating, and ensuring a stable energy-saving effect during long-term operation of the motor;

[0003] When the UAV encounters sandy dust weather, during flight, due to the heat dissipation requirement, the air inside the motor needs to be exchanged with the outside air, resulting in dust flowing into the motor with the air flow, affecting the operation of the motor and causing the UAV to malfunction. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0005] An unmanned aerial vehicle (UAV) motor with heat dissipation and dust prevention functions, comprising:

[0006] A shell cylinder, a fixing ring is fixedly installed on the outer side of the shell cylinder, and a stator is fixedly installed on the inner wall of the shell cylinder;

[0007] An end cover, the end cover is installed at one end of the shell cylinder, and a rotating shaft is rotatably installed inside the end cover. A rotor is fixedly installed on the outer side of the rotating shaft, and the rotor is located inside the stator;

[0008] A heat dissipation mechanism, the heat dissipation mechanism is installed on the side of the inner wall of the shell cylinder away from the end cover;

[0009] One end of the shell cylinder away from the end cover is fixedly installed with a cover cylinder. Uniform through slots are provided at one end of the outer side of the cover cylinder close to the shell cylinder, and air inlet slots are uniformly provided on the side of the cover cylinder away from the shell cylinder. A conical cover is fixedly installed on the inner wall of the cover cylinder. The outer diameter of the conical cover gradually increases in the process of approaching the shell cylinder. Uniform inclined through slots are provided on the outer side of the conical cover. By means of the cooperation of the conical cover and the inclined guide plate with the air inlet slots and through slots of the cover cylinder, after driving the air to enter in a spiral motion, taking advantage of the fact that the mass of dust and impurities is greater than that of air, the dust and impurities in the air are concentrated at the position close to the inner wall of the cover cylinder, and are led out of the motor through the through slots during the air flow process, avoiding that when the drone is used in sandy weather, dust and impurities enter the interior of the motor during the heat dissipation process of the motor operation, causing pollution to the internal parts of the motor and resulting in a short circuit of the motor. And an inclined guide plate is fixedly installed on the outer side of the conical cover. The inclined guide plates are uniformly installed along the center position of the conical cover, and the inclined guide plates are located between the inclined through slots. The side of the inclined guide plate away from the conical cover is in contact with the inner wall of the cover cylinder.

[0010] Preferably, the heat dissipation mechanism includes an inner hole disk. One side of the inner hole disk close to the shell cylinder is fixedly connected to the inner wall of the shell cylinder, and a first bearing is fixedly installed on the inner wall of the inner hole disk. The inner wall of the first bearing is fixedly connected to the outer side of the rotating shaft. Uniform through holes are provided on the outer side of the inner hole disk, and an annular groove is provided on the side of the inner hole disk away from the end cover. A sponge ring plate is fixedly installed at the annular groove of the inner hole disk. By means of the cooperation of the sponge ring plate and the inner hole disk, when guiding the air into the gap between the stator and the rotor of the motor to reduce the internal temperature, the introduced air is filtered again, assisting the cover cylinder and the conical cover to improve the dust removal effect. At the same time, the sponge has good water absorption, and can effectively absorb the moisture in the air, avoiding a large amount of moisture from entering and evaporating to damage the electrical components and affecting the circuit conduction.

[0011] Preferably, a clamping groove is provided at one end of the first bearing away from the end cover. A clamping sleeve is clamped at the clamping groove of the first bearing. The clamping sleeve is located on the side of the inner hole disk away from the end cover. An impeller is fixedly installed on the outer side of the clamping sleeve. Uniform spiral blades are provided on the outer side of the impeller. A wind guide cylinder is installed at one end of the clamping sleeve away from the rotating shaft. The wind guide cylinder is located inside the conical cover.

[0012] Preferably, one end of the air guide cylinder close to the cover cylinder is fixedly connected to the inner wall of the cover cylinder. The end of the air guide cylinder far from the cover cylinder is in contact with the outer side of the clamping sleeve, and the outer diameter of the air guide cylinder gradually decreases as it approaches the clamping sleeve. The end cover includes a fixed cover, which is fixedly installed at the end of the shell cylinder far from the cover cylinder. Heat dissipation grooves are evenly formed on the outer side of the fixed cover. By matching the heat dissipation grooves of the fixed cover with the rectangular grooves of the inner sliding cover and using the staggered arrangement of the heat dissipation grooves and the rectangular grooves, during the flight of the drone, while ensuring the heat dissipation effect, it cooperates with the outer ring plate to block foreign impurities from entering the motor, ensuring the normal operation of the motor during the flight of the drone. An outer ring plate is fixedly installed on the outer side of the fixed cover, and the outer ring plate is located at the heat dissipation grooves of the fixed cover. A dust-proof cover is fixedly installed at the central position of the outer side of the fixed cover. One end of the dust-proof cover far from the fixed cover inclines inwards, and air holes are evenly formed on the outer side of the dust-proof cover. An inner arc ring is fixedly installed on the inner wall of the dust-proof cover. One end of the inner arc ring far from the dust-proof cover is arc-shaped. By cooperating the inner arc ring with the dust-proof cover, while retaining the air flow path to assist heat dissipation, the inner arc ring blocks the dust particles entering through the air holes, preventing the dust particles from contacting the bearing, resulting in the obstruction of the bearing rotation, increasing the useless work of the motor and the energy consumption.

[0013] Preferably, a second bearing is fixedly installed on the inner wall of the fixed cover. The inner wall of the second bearing is fixedly connected to the outer side of the rotating shaft. An inner sliding cylinder is fixedly installed on the side of the fixed cover close to the stator. An inner sliding cover is slidably installed on the outer side of the inner sliding cylinder. A gasket ring is fixedly installed between the inner sliding cover and the fixed cover. The gasket ring is made of rubber material. Due to the rubber material of the gasket ring, when the air impacts the inner sliding cover, the pressure compresses the gasket ring to deform, reducing the distance between the inner sliding cover and the fixed cover, decreasing the air flow gap, increasing the air flow rate in the gap, enabling the heat to be quickly exported with the air, and improving the heat dissipation effect. Rectangular grooves are evenly clamped on the outer side of the inner sliding cover, and the rectangular grooves and the heat dissipation grooves are arranged in a staggered manner.

[0014] The present invention provides a drone motor with heat dissipation and dust-proof functions, having the following beneficial effects:

[0015] First, for the drone motor with heat dissipation and dust-proof functions, through the cooperation of the conical cover and the inclined guide plate with the air inlet groove and the through groove of the cover cylinder, after driving the air to enter in a spiral motion, by using the characteristics that the mass of dust and impurities is greater than that of air, the dust and impurities in the air are concentrated at the position close to the inner wall of the cover cylinder and are led out of the motor through the through groove during the air flow process, avoiding the entry of dust and impurities into the interior of the motor during the heat dissipation process of the motor when the drone is used in sandy weather, causing pollution to the internal parts of the motor and resulting in a short circuit of the motor.

[0016] Second, the drone motor with heat dissipation and dust prevention functions uses a sponge ring plate in cooperation with an inner hole disk. When introducing air into the gap between the motor stator and rotor to reduce the internal temperature, it re-filters the introduced air, and the auxiliary cover cylinder and the conical cover improve the dust removal effect. At the same time, the sponge has good water absorption, which can effectively absorb the moisture in the air, prevent a large amount of moisture from entering and evaporating to damage electrical components, and affect the circuit conduction.

[0017] Third, the drone motor with heat dissipation and dust prevention functions uses the heat dissipation slots of the fixed cover in cooperation with the rectangular slots of the inner sliding cover. By arranging the heat dissipation slots and the rectangular slots alternately, during the flight of the drone, while ensuring the heat dissipation effect, it cooperates with the outer ring disk to block foreign impurities from entering the motor, ensuring the normal operation of the motor during the flight of the drone.

[0018] Fourth, the drone motor with heat dissipation and dust prevention functions uses the inner arc ring in cooperation with the dust-proof cover. While retaining the air circulation path to assist heat dissipation, the inner arc ring blocks the dust particles entering through the air holes, preventing the dust particles from contacting the bearing, resulting in the rotation of the bearing being blocked, increasing the useless work of the motor, and increasing energy consumption.

[0019] Fifth, the drone motor with heat dissipation and dust prevention functions uses the rubber material of the gasket ring. When the air impacts the inner sliding cover, the pressure compresses the gasket ring to deform, reducing the distance between the inner sliding cover and the fixed cover, decreasing the air circulation gap, increasing the air flow rate in the gap, enabling the heat to be quickly exported with the air, and improving the heat dissipation effect.

[0035] An end cover 2, the end cover 2 is installed at one end of the shell cylinder 1, and a rotating shaft 3 is rotatably installed inside the end cover 2, and a rotor 9 is fixedly installed on the outer side of the rotating shaft 3, and the rotor 9 is located inside the stator 10;

The side of the cover cylinder 5 close to the shell cylinder 1 is evenly provided with through grooves, and the side of the cover cylinder 5 away from the shell cylinder 1 is evenly provided with air inlet grooves. The inner wall of the cover cylinder 5 is fixedly installed with a conical cover 6. When the motor is in operation, the heat dissipation mechanism 8 drives the outside air to enter the motor interior from the air inlet grooves of the cover cylinder 5. At the same time, during the flowing process, the air drives the dust and floating impurities to spiral in from the air inlet grooves. The outer diameter of the conical cover 6 gradually increases in the process of getting closer to the shell cylinder 1. The outer side of the conical cover 6 is evenly provided with inclined through grooves, and the outer side of the conical cover 6 is fixedly installed with inclined guide plates 7. The inclined guide plates 7 are evenly installed along the center position of the conical cover 6. After entering, through the cooperation of the inclined guide plates 7 and the conical cover 6, by using the change of the conical outer diameter of the conical cover 6 and the cooperation of the inclined guide plates 7, during the spiral entry of the air, by using the fact that the mass of the dust and impurities is greater than that of the air, during the spiral flowing process, the dust and impurities are concentrated in the range close to the inner wall of the cover cylinder 5, so that the air and impurities are restricted and guided by the inclined guide plates 7 during the flowing process, and are led out of the cover cylinder from the through groove position. And the inclined guide plates 7 are located between the inclined through grooves, and the side of the inclined guide plates 7 away from the conical cover 6 is in contact with the inner wall of the cover cylinder 5.

[0038] The second embodiment, on the basis of the first embodiment, please refer to Figures 5 to 7 As shown, the heat dissipation mechanism 8 includes an inner hole disk 81. The side of the inner hole disk 81 close to the shell cylinder 1 is fixedly connected to the inner wall of the shell cylinder 1, and the inner wall of the inner hole disk 81 is fixedly installed with a first bearing 82. The inner wall of the first bearing 82 is fixedly connected to the outer side of the rotating shaft 3. The outer side of the inner hole disk 81 is evenly provided with through holes. Through the clamping connection of the clamping sleeve 86 and the rotating shaft 3, during the operation process, the rotating shaft 3 drives the clamping sleeve 86, so that the clamping sleeve 86 drives the impeller 85. By using the spiral vanes of the impeller 85, during the rotation process, the outside air is driven to spiral into the motor interior, and through the guiding of the air guiding cylinder 84, the air impacts the sponge ring plate 83 under the drive of the impeller 85, and the sponge ring plate 83 is used to filter the air again. At the same time, by using the water absorption of the sponge, the moisture in the air is absorbed. And the side of the inner hole disk 81 away from the end cover 2 is provided with an annular groove, and the sponge ring plate 83 is fixedly installed at the annular groove of the inner hole disk 81.

[0039] A clamping groove is provided at one end of the first bearing 82 away from the end cover 2. A clamping sleeve 86 is clamped at the clamping groove of the first bearing 82. The clamping sleeve 86 is located on the side of the inner hole disk 81 away from the end cover 2. An impeller 85 is fixedly installed on the outer side of the clamping sleeve 86. Subsequently, the air passes through the inner hole disk 81, and after passing through the inner hole disk 81, it enters the gap between the rotor 9 and the stator 10, absorbs the heat generated by the work between the rotor 9 and the stator 10, and impacts the end cover 2 after absorbing the heat for exhaust heat dissipation. The outer side of the impeller 85 is evenly provided with spiral vanes. A guide cylinder 84 is installed at one end of the clamping sleeve 86 away from the rotating shaft 3. The guide cylinder 84 is located inside the conical cover 6.

[0040] The third embodiment is based on the first and second embodiments. Figures 8 to 10 As shown, one end of the air guide tube 84 close to the cover tube 5 is fixedly connected to the inner wall of the cover tube 5, and one end of the air guide tube 84 away from the cover tube 5 contacts the outer side of the ferrule 86, and the outer diameter of the air guide tube 84 gradually decreases as it approaches the ferrule 86. The end cover 2 includes a fixed cover 21, which is fixedly installed on the end of the shell tube 1 away from the cover tube 5. Heat dissipation grooves are evenly opened on the outer side of the fixed cover 21, and an outer ring disk 22 is fixedly installed on the outer side of the fixed cover 21. The outer ring disk 22 is located at the heat dissipation groove of the fixed cover 21. After absorbing the internal heat, The air flow impacts the inner sliding cover 26, and cooperates with the heat dissipation groove of the fixed cover 21 through the rectangular groove of the inner sliding cover 26. The heat dissipation groove and the rectangular groove rubber groove are arranged to summarize during the exhaust process to prevent dust from directly entering between the stator 10 and the rotor 9. A dust cover 23 is fixedly installed at the center position of the outer side of the fixed cover 21. The end of the dust cover 23 away from the fixed cover 21 is inclined inward, and air holes are evenly opened on the outer side of the dust cover 23. An inner arc ring 24 is fixedly installed on the inner wall of the dust cover 23. The end of the inner arc ring 24 away from the dust cover 23 is curved in an arc shape.

[0041] A second bearing 28 is fixedly installed on the inner wall of the fixed cover 21, and the inner wall of the second bearing 28 is fixedly connected to the outer side of the rotating shaft 3, and an inner slide cylinder 27 is fixedly installed on the side of the fixed cover 21 close to the stator 10, and an inner slide cover 26 is slidably installed on the outer side of the inner slide cover 27. When the inner slide cover 26 is impacted, the pressure is transmitted to the gasket 25 through the inner slide cover 26, so that the gasket 25 is deformed under pressure, reducing the distance between the fixed cover 21 and the inner slide cover 26, so that the air flow speed between the fixed cover 21 and the inner slide cover 26 is accelerated, and at the same time, the holes on the surface of the dust cover 23 cooperate with the inner arc ring 24, while assisting the internal heat dissipation, the inner arc ring 24 prevents external dust from contacting the second bearing 28, and a gasket 25 is fixedly installed between the inner slide cover 26 and the fixed cover 21. The gasket 25 is made of rubber material, and rectangular grooves are evenly arranged on the outer side of the inner slide cover 26, and the rectangular grooves and the heat dissipation grooves are staggered.

[0042] When in use, it is connected to the drone through the fixing ring 4, and the rotating shaft 3 is connected to the propeller drive shaft of the drone through the coupling. When the drone is started, the stator 10 is energized to generate an electromagnetic field, so that the rotor 9 drives the rotating shaft 3 to rotate, and the rotating shaft 3 transmits power to the outside through the coupling, while driving the heat dissipation mechanism 8 to operate, so that the heat dissipation mechanism 8 drives the outside air to exchange with the air inside the motor, realizes circulation flow, and performs heat dissipation treatment. At the same time, during the air flow, the heat dissipation mechanism 8 cooperates with the cover tube 5 to perform dust prevention treatment.

[0043] During the air flow, when the motor is in working state, the heat dissipation mechanism 8 drives the outside air into the motor through the air inlet slot of the cover tube 5. At the same time, during the flow, the air drives the dust and floating impurities to spiral in through the air inlet slot. After entering, the air is matched with the conical cover 6 through the inclined guide plate 7. The change of the conical outer diameter of the conical cover 6 is used to match the inclined guide plate 7. During the process of the air spirally entering, the dust and impurities are concentrated in the area close to the inner wall of the cover tube 5 by utilizing the characteristic that the mass of the dust and impurities themselves is greater than that of the air. During the spiral flow, the air and impurities are restricted and guided by the inclined guide plate 7 during the flow, so that they are guided out of the cover tube from the through groove position.

[0044] In the heat dissipation mechanism 8, through the clamping connection between the sleeve 86 and the rotating shaft 3, during the operation, the rotating shaft 3 drives the sleeve 86, so that the sleeve 86 drives the impeller 85, and the spiral blades of the impeller 85 drive the external air to spiral into the interior of the motor during the rotation, and through the guidance of the air guide tube 84, the air is guided by the impeller 85 to hit the sponge ring plate 83 downward, and the sponge ring plate 83 is used to filter the air again. At the same time, the water absorption of the sponge is used to absorb the moisture in the air. Then the air passes through the inner hole disk 81, and then enters the gap between the rotor 9 and the stator 10 after passing through the inner hole disk 81, absorbs the heat generated by the work between the rotor 9 and the stator 10, and hits the end cover 2 after absorbing the heat, so as to exhaust and dissipate heat.

[0045] In the end cover 2, after absorbing the internal heat, the air flows and impacts the inner sliding cover 26, and cooperates with the heat dissipation groove of the fixed cover 21 through the rectangular groove of the inner sliding cover 26. The heat dissipation groove and the rectangular groove rubber groove are arranged to be summarized in the exhaust process to prevent dust from directly entering between the stator 10 and the rotor 9. At the same time, when impacting the inner sliding cover 26, the pressure is transmitted to the gasket 25 through the inner sliding cover 26, so that the gasket 25 is deformed under pressure, reducing the distance between the fixed cover 21, and accelerating the air flow speed between the fixed cover 21 and the inner sliding cover 26. At the same time, the holes on the surface of the dust cover 23 cooperate with the inner arc ring 24, while assisting in the internal heat extraction, the inner arc ring 24 prevents external dust from contacting the second bearing 28.
