Description

Technical Field

[0001] The invention relates to the technical field of motors, and in particular to a waterproof and moisture-proof motor. Background Art

[0002] A brushless motor is an electric motor. Compared with a traditional brushed motor, a brushless motor does not require carbon brushes to transmit current, so it has higher efficiency, less noise and longer service life. Drones usually use brushless motors as power sources because brushless motors have the characteristics of high efficiency, high speed and high power, which are very suitable for the needs of aircraft.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0032] Reference Figure 1-Figure 9A waterproof and moisture-proof motor comprises a connecting plate 2, a housing 1 is fixedly connected to the connecting plate 2, and a dual-output shaft body 3 (the dual-output shaft body 3 comprises a stator, a rotor, a control system, etc. of a brushless motor, which are not described in detail here) is arranged in the housing 1, a first mounting box 5 is fixedly connected to the top of the housing 1, a vent hole 11 is provided in the center of the first mounting box 5, a first output rotor 4 at the top of the dual-output shaft body 3 passes through the vent hole 11 and extends to the top of the first mounting box 5; a sealing portion is arranged on the first output rotor 4, and a sealing end of the sealing portion is connected to the bottom of the first mounting box 5. The vent holes 11 are against each other; the mounting cylinder 24 is fixedly connected in the outer shell 1, covered on the outer side of the dual output shaft body 3, and a cavity for air flow is arranged between the dual output shaft body 3; the vent portion is arranged in the outer shell 1, the air inlet end of the vent portion extends to the top of the first mounting box 5, and the exhaust end of the vent portion extends to the bottom of the dual output shaft body 3 and is connected to the cavity, the first output rotor 4 is fixedly connected with the first magnetic ring 6, the vent hole 11 on the top of the first mounting box 5 is fixedly connected with the second magnetic ring 7, the first magnetic ring 6 is arranged on the inner side of the second magnetic ring 7, and the first magnetic ring 6 and the second magnetic ring 7 repel each other.

[0033] When in use, the fan blades of the drone are installed on the first output rotor 4, and the dual output shaft body 3 is energized to drive the rotor of the dual output shaft body 3 to rotate. When the first output rotor 4 rotates, the repulsive magnetic force between the first magnetic ring 6 and the second magnetic ring 7 makes the first output rotor 4 rotate more stably.

[0034] The first output rotor 4 drives the UAV fan blades to rotate. When the UAV fan blades rotate, the air is disturbed to form a downward impact airflow. Part of the airflow is transmitted to the bottom of the dual output shaft body 3 through the ventilation part, and then the incoming airflow is dried and dusted through the ventilation part. The treated air is discharged into the installation tube 24, absorbs the heat emitted by the dual output shaft body 3, and cools the dual output shaft body 3. Then, as the pressure of the gas inside the shell 1 increases, the high air pressure drives the sealing part to rise and separate from the vent 11, thereby avoiding wear of the sealing part when the rotor rotates. The air pressure inside the shell 1 is greater than the air pressure inside the first installation box 5. The gas in the shell 1 is sprayed into the first installation box 5, thereby preventing external humid air and water from entering the shell 1 to cause corrosion to the dual output shaft body 3. When the UAV stops working, the first output rotor 4 stops working and stops supplying air to the inside of the shell 1, so that the pressure inside the shell 1 is restored to be consistent with the pressure inside the first installation box 5, and the vent 11 is sealed again from the sealing part to prevent external humid air from entering the shell 1 to cause corrosion to the dual output shaft body 3.

[0035] Reference Figure 6 and Figure 7The sealing part includes a shielding plate 8 fixedly connected to the first output rotor 4 and a sealing plate 10 slidably connected to the first output rotor 4. A spring 9 is fixedly connected to the sealing plate 10, and the top of the spring 9 is fixedly connected to the bottom of the shielding plate 8.

[0036] When the air pressure inside the housing 1 increases, under the action of the air pressure difference, the air drives the sealing disk 10 to slide above the first output rotor 4, and at the same time drives the spring 9 to contract. The sealing disk 10 moves upward to connect the vent 11, and then the gas inside the housing 1 flows into the first installation box 5, preventing external water and humid air from entering the housing 1 and corroding the dual output shaft body 3. Since the sealing disk 10 is no longer in contact with the first installation box 5 after rising, wear of the sealing disk 10 is avoided, thereby ensuring the moisture-proof effect of the motor.

[0037] When the first output rotor 4 stops rotating and the pressure in the housing 1 and the first mounting box 5 is balanced, the spring 9 rebounds and drives the sealing disk 10 to descend, thereby blocking the vent hole 11 to prevent external water and humid air from entering the housing 1 .

[0038] Reference Figure 1-Figure 9The ventilation part includes a drainage unit arranged on the bottom inner wall of the shell 1, an air intake unit arranged above the drainage unit, and a filter unit arranged above the drainage unit. The air intake end of the air intake unit extends into the first installation box 5, the drainage end at the bottom of the air intake unit is connected to the water intake end of the drainage unit, the exhaust end of the side wall of the air intake unit is connected to the air intake end of the filter unit, and the exhaust end of the filter unit is connected to the bottom of the installation cylinder 24. The drainage unit includes a water collecting box 16 fixedly connected to the bottom inner wall of the shell 1, and the bottom of the water collecting box 16 is fixedly connected with a drainage pipe 17, and the drainage pipe 17 is fixedly connected with a pressure relief valve 18; The air inlet unit includes a downpipe 26 fixedly connected to the top of the water collecting box 16, the top of the downpipe 26 is communicated with the bottom of the first installation box 5, and a second one-way valve 27 is arranged in the downpipe 26, the air inlet unit includes a first air pipe 21 fixedly connected to the top of the water collecting box 16, the bottom of the first air pipe 21 is fixedly connected to the first one-way valve 23, the top of the first air pipe 21 extends into the first installation box 5, the side wall of the first air pipe 21 is fixedly connected to the bronchus 22, the bronchus 22 is connected to the filter unit, the filter unit includes an air collecting box 20 fixedly connected to the top of the water collecting box 16, the bronchus 22 is connected to the air collecting box 20, and the air collecting box 20 is connected to the air collecting box 20. The top of the box 20 is fixedly connected with the second installation box 14, and the top of the gas collection box 20 is communicated with the second installation box 14, the top of the second installation box 14 is fixedly connected with the gear reduction module 12, the input end of the gear reduction module 12 is fixedly connected to the second output rotor of the dual output shaft body 3, the output end of the gear reduction module 12 is fixedly connected with the reduction output rotor 13, the reduction output rotor 13 extends into the second installation box 14 and is fixedly connected with the filter assembly 15, the filter assembly 15 includes a mounting frame 1501 rotatably connected to the second installation box 14, and the mounting frame 1501 is fixedly connected with the filter plate 15 02. Two groups of symmetrical through holes are provided on the second installation box 14, wherein the bottom of one group of through holes (referred to as Group A for the sake of convenience) is connected to the gas collecting box 20, and the top is fixedly connected to a connecting pipe 19, and the top of the connecting pipe 19 is connected to the bottom of the installation tube 24; the top of the other group of through holes (referred to as Group B for the sake of convenience) is fixedly connected to a connector 30, and the side wall of the connector 30 is fixedly connected to a second air pipe 29, and the air inlet at the top of the second air pipe 29 extends into the first installation box 5, and the bottom of the connector 30 is fixedly connected to an exhaust pipe 31, and the exhaust pipe 31 extends to the bottom of the outer shell 1.

[0039] Part of the airflow generated by the fan blades of the drone enters the first air pipe 21. When it rains, rainwater is discharged into the water collecting box 16 along the first one-way valve 23. As the pressure inside the water collecting box 16 increases, that is, when the pressure reaches the preset value of the pressure relief valve 18, the water in the water collecting box 16 is discharged through the pressure relief valve 18, and the airflow enters the air collecting box 20 through the bronchus 22, and is discharged into the second installation box 14 through the air collecting box 20. The moisture in the air is removed by the filter plate 1502 to generate dry air. The dry air enters the installation cylinder 24 through the connecting pipe 19 and absorbs the heat emitted by the dual output shaft body 3, cools the dual output shaft body 3, and then carries the heat into the outer shell. 1, as the pressure inside the shell 1 increases, the hot air drives the sealing disk 10 to rise and flow into the first installation box 5. The downward airflow generated by the rotation of the UAV fan blades prevents the hot air in the first installation box 5 from leaking out. The hot air in the first installation box 5 is discharged into the second installation box 14 from above the through holes of the group B through the second air pipe 29, passes through the filter plate 1502 within the range of the through holes of the group A, and recoils the filter plate 1502. The recoil of the filter plate 1502 by the hot air flow can not only clean the blocked holes on the filter plate 1502, but also accelerate the volatilization of water molecules on the filter plate 1502 to help them be discharged from the shell 1, thereby improving the filtering effect of the filter plate 1502.

[0040] When the waterproof and moisture-proof motor is installed on a drone, on the one hand, the airflow generated by the rotation of the fan blades driven by the drone drives the sealing disk 10 to rise, thereby preventing the sealing disk 10 from being worn due to friction when the rotor rotates, thereby preventing the sealing disk 10 from leaking when it is stationary, thereby avoiding the deterioration of the sealing effect of the motor. On the other hand, the filter component 15 dehumidifies and removes dust from the humid air to generate dry and clean gas, which is directly blown toward the dual-output shaft body 3, contact-cooling the dual-output shaft body 3, thereby improving the cooling effect of the motor.

[0041] At the same time, the second output rotor of the dual-output shaft body 3 drives the input shaft of the gear reduction module 12 (gear reducer) to rotate, reduces the output torque through the gears inside it, and drives the mounting frame 1501 to rotate, so that the hot air flow backwashes the four filter plates 1502 in a cycle, and uses the air flow that cools the dual-output shaft body 3 to backwash the filter plate 1502, thereby accelerating the drying and dust removal of the filter plate 1502, thereby ensuring the filtering effect of the filter plate 1502 during long-term operation.

[0042] It should be noted that in order to improve the cooling effect on the dual output shaft body 3, an air guide plate 25 is fixedly connected to the mounting tube 24, and the air guide plate 25 is spiral. The airflow is guided through the spiral air guide plate 25, thereby increasing the contact time with the dual output shaft body 3, improving the cooling effect on the dual output shaft body 3 and increasing the temperature of the airflow, thereby improving the drying effect on the filter plate 1502.

[0043] The sealing disc 10 is made of sealing materials such as rubber, and the filter plate 1502 is preferably a filter sponge.

[0044] Reference Figure 6 A baffle 28 is fixedly connected to the first installation box 5 , and the baffle 28 is an annular plate. The bottom of the first installation box 5 is a frustum with a narrow top and a wide bottom. The baffle 28 is used to intercept the water flow and make it flow into the downpipe 26 .

[0045] To sum up, when the waterproof and moisture-proof motor is installed on a drone, on the one hand, the airflow generated by the rotation of the fan blades driven by the drone drives the sealing disk 10 to rise, thereby preventing the sealing disk 10 from being worn due to friction when the rotor rotates, thereby preventing the sealing disk 10 from leaking when it is stationary, thereby avoiding the deterioration of the sealing effect of the motor. At the same time, when the first output rotor 4 rotates, the air pressure inside the outer shell 1 and the first mounting box 5 is greater than the air pressure outside the motor, thereby preventing external humid air from entering the outer shell 1 through the gap between the first magnetic ring 6 and the second magnetic ring 7, thereby ensuring the waterproof and moisture-proof function of the motor while improving the stability of the first output rotor 4 during rotation.

[0046] On the other hand, the filter assembly 15 is used to dehumidify and remove dust from the moist air to generate dry clean gas, which is directly blown toward the dual output shaft body 3 to perform contact cooling on the dual output shaft body 3, thereby improving the cooling effect of the motor;

[0047] On the other hand, the airflow used to cool the dual output shaft body 3 is used to backwash the filter plate 1502, thereby accelerating the drying and dust removal of the filter plate 1502, thereby ensuring the filtering effect of the filter plate 1502 during long-term operation.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
