Description

[0002] An electric motor (commonly known as a "motor") is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction.

DETAILED DESCRIPTION

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0033] The present invention provides a motor, such as Figures 1-8 As shown, the main body includes a front cover 11, a rear cover, a base 13, a fan 14, a wind cover 15, etc. A stator 16 is fixedly installed on the inner side of the base 13, a rotor 17 is connected to the front cover 11 and the rear cover for common rotation, a rotating shaft 18 is fixedly connected to the side of the rotor 17 close to the front cover 11, a bearing 19 is fixedly sleeved on the outside of the rotating shaft 18, and the bearing 19 is fixedly sleeved inside the front cover 11, and an auxiliary heat dissipation mechanism 2 is provided between the front cover 11 and the rotor 17;

[0034] The auxiliary heat dissipation mechanism 2 includes a plurality of heat dissipation grooves 21 evenly provided on the surface of the front end cover 11, and a non-magnetic sheet 22 is symmetrically fixedly sleeved on the outside of the rotor 17. A group of fan blades 23 used in conjunction with the heat dissipation grooves 21 are fixedly connected to the side of the two non-magnetic sheets 22 away from each other, and two convex rings 24 are symmetrically provided between one of the non-magnetic sheets 22 and the front end cover 11, one of the convex rings 24 is fixedly connected to the non-magnetic sheet 22 and fixedly sleeved on the outside of the rotating shaft 18, and the other convex ring 24 is movably sleeved on the outside of the rotating shaft 18 and fixedly sleeved with a guide ring 25, and a dustproof sheet 26 is slidably sleeved on the outside of the guide ring 25, and a first through groove 27 used in conjunction with the plurality of heat dissipation grooves 21 is provided on the surface of the dustproof sheet 26, and a plurality of protrusions 28 used in conjunction with the heat dissipation grooves 21 are evenly fixedly connected to the side of the dustproof sheet 26 close to the front end cover 11;

[0035] Four grooves 29 are evenly formed on the outer sides of the two convex rings 24. Connecting rods 30 are hingedly connected to the interiors of the four groups of grooves 29. The four groups of connecting rods 30 are hinged to each other on the side away from the convex rings 24. H-shaped plates 31 are fixedly sleeved at the hinged joints of the four groups of connecting rods 30. Plumb bobs 32 are provided on the side of the four H-shaped plates 31 away from the rotating shaft 18, and the four plumb bobs 32 are fixedly connected to the H-shaped plates 31. A first spring 33 is fixedly connected between the two convex rings 24 and movably sleeved on the outside of the rotating shaft 18. A plurality of ridges 34 are evenly provided between the two convex rings 24. The plurality of ridges 34 are respectively fixedly connected to one of the convex rings 24. Slots 35 for use with the ridges 34 are evenly provided on the inner side of the other convex ring 24.

[0036] The outer side of the dustproof sheet 26 is evenly fixed with a plurality of sliders 36, and the inner side of the front cover 11 is evenly provided with a plurality of slide grooves 37 for use with the sliders 36, and the plurality of slide grooves 37 are composed of two straight grooves and one oblique groove;

[0037] When the motor is in use, the rotor 17 rotates while driving the front and rear sets of fan blades 23 to rotate synchronously, cooperating with the fan 14 to accelerate the air circulation inside the motor and improve the heat dissipation effect of the motor rotor 17;

[0038] At the same time, as the rotor 17 rotates, it drives the two convex rings 24 and multiple groups of connecting rods 30 to rotate synchronously. At this time, the multiple groups of connecting rods 30 drive the plumb bobs 32 to rotate synchronously through the H-shaped plates 31, and through the centrifugal force of the high-speed rotation of the rotor 17 and the gravity of the plumb bobs 32 themselves, the other convex ring 24 is driven to move along the multiple convex strips 34 in the direction away from the front end cover 11 and squeeze the first spring 33, so that the convex ring 24 drives the dustproof sheet 26 to move synchronously to the side away from the front end cover 11 through the guide ring 25. When the dustproof sheet 26 moves, it drives multiple sliders 36 to move synchronously inside the slide groove 37, first moving horizontally along the straight groove in the slide groove 37 When the slider 36 moves, the dustproof sheet 26 drives the multiple groups of protrusions 28 to move out from the inside of the multiple groups of heat dissipation grooves 21 to release the blocking effect of the multiple protrusions 28 on the heat dissipation grooves 21. When the slider 36 moves inside the inclined groove in the slide groove 37, the multiple sliders 36 simultaneously drive the dustproof sheet 26 to rotate a certain angle, so that the multiple first through-grooves 27 on the surface of the dustproof sheet 26 respectively coincide with the positions of the multiple groups of heat dissipation grooves 21 on the surface of the front cover 11. At this time, the air in the motor can circulate through the first through-grooves 27, the heat dissipation grooves 21 and the heat dissipation holes on the fan cover 15 under the action of the fan 14 and the two groups of fan blades 23, thereby improving the heat dissipation effect of the rotor 17 during the use of the motor;

[0039] When the motor is not in use, the rotor 17 stops rotating. At this time, the centrifugal force caused by the rapid rotation disappears, and one of the protruding rings 24 moves toward the front end cover 11 under the restoring action of the first spring 33. The dustproof sheet 26 is again fitted to the inner wall of the front end cover 11 through the cooperation between the above structures, and the multiple groups of protruding blocks 28 are inserted into the heat dissipation grooves 21 again, thereby blocking the multiple groups of heat dissipation grooves 21 and preventing dust from entering the interior of the motor through the heat dissipation grooves 21 when the motor is not in use.

[0040] The present invention is provided with an auxiliary heat dissipation mechanism 2, which not only can improve the heat dissipation effect of the rotor 17 when the motor is in use, but also can effectively extend the service life of the rotor 17, and when the motor is stopped, the heat dissipation groove 21 on the front cover 11 can be automatically blocked to prevent dust from entering, which can effectively improve the practicality of the auxiliary heat dissipation mechanism 2 and increase the overall practicality of the motor and rotor 17.

[0041] like Figures 1-8 As shown, the surface of the front cover 11 is fixedly connected with an oil tank 4, and the oil tank 4 is arranged just above the rotating shaft 18. An automatic lubrication mechanism 5 is provided on one side of the oil tank 4 for use with the bearing 19.

[0042] The automatic lubrication mechanism 5 includes a liquid inlet groove 51 provided on the top of the bearing 19 and the surface of the front end cover 11. An oil outlet pipe 52 is fixedly connected to one end of the bottom of the oil tank 4. The bottom end of the oil outlet pipe 52 is fixedly connected to the front end cover 11 and connected to the liquid inlet groove 51. The cross-section of the top end of the oil outlet pipe 52 is funnel-shaped. A piston 53 is slidably connected to the interior of the oil outlet pipe 52. A positioning ring 54 is fixedly connected to the interior of the oil tank 4. A round rod 55 is slidably connected to the interior of the positioning ring 54. The bottom end of the round rod 55 extends to the interior of the oil outlet pipe 52 and is fixedly connected to the piston 53.

[0043] One end of the top of the round rod 55 is fixedly connected to a round pin 56 through a square block. The outside of the round pin 56 is symmetrically and movably sleeved with a square plate 57. The surfaces of the two square plates 57 are provided with a second through groove 58 used in conjunction with the round pin 56. The inside of the oil tank 4 is symmetrically and fixedly connected to a fixing rod 59, and the two fixing rods 59 are respectively arranged on both sides of the round rod 55. The outside of the two fixing rods 59 is movably sleeved with a side plate 60. The top end of the side plate 60 is fixedly connected to the two square plates 57 respectively. A tension spring 61 is symmetrically fixedly connected to the side of the side plate 60 away from the round rod 55, and the two tension springs 61 are movably sleeved on the outside of the two fixed rods 59. The sides of the two tension springs 61 away from the side plate 60 are fixedly connected to the inner wall of the oil tank 4. A T-shaped plate 62 is fixedly connected between the two square plates 57, and the T-shaped plate 62 is arranged on the side of the two square plates 57 away from the side plate 60. The side of the T-shaped plate 62 away from the square plates 57 extends to the inner side of the front cover 11 and is fixedly connected to a push block 63.

[0044] The dust-proof piece 26 is fixedly connected to the limiting piece 64 on the side away from the oil tank 4, and the cross-sectional shape of the limiting piece 64 is U-shaped. A hollow block 65 is slidably connected between the limiting piece 64 and the dust-proof piece 26, and the hollow block 65 is arranged just below the T-shaped plate 62. A cross plate 66 is slidably connected inside the hollow block 65, and a protrusion is provided at the bottom end of the cross plate 66 for use with the hollow block 65. The side of the cross plate 66 close to the oil tank 4 is fixedly connected to the front end cover 11. A slot 67 is provided at the top end of the hollow block 65. A T-shaped block 68 for use with the push block 63 is slidably connected inside the slot 67. A second spring 69 is fixedly connected to the bottom end of the T-shaped block 68, and one end of the bottom of the second spring 69 is fixedly connected to the inner wall of the slot 67.

[0045] The surface of the push block 63 away from the T-shaped plate 62 and the surface of the T-shaped block 68 close to the oil tank 4 are respectively set as parallel inclined surfaces. The oil tank 4 is made of transparent visible material.

[0046] The side section of the bottom end of the oil tank 4 is funnel-shaped, and the top end of the oil tank 4 is provided with an externally threaded pipe for refueling, and the external thread of the externally threaded pipe is sleeved with a sealing cap;

[0047] During the use of the above-mentioned motor, when the auxiliary heat dissipation mechanism 2 is used to dissipate heat from the rotor 17, the dustproof sheet 26 moves and drives the limiting sheet 64 to move synchronously, so that the limiting sheet 64 cooperates with the dustproof sheet 26 to drive the hollow block 65 to move synchronously on the outside of the cross plate 66, so that the hollow block 65 drives the T-shaped block 68 to move synchronously. During the movement of the T-shaped block 68, it first conflicts with the push block 63 on one side of the T-shaped plate 62, and drives the T-shaped plate 62 to move toward the side close to the rotor 17 through the push block 63. At this time, the T-shaped plate 62 drives the two square plates 57 to move synchronously, so that the two square plates 57 simultaneously drive the side plates 60 to slide on the outside of the two fixing rods 59 and stretch the two tension springs 61. As the two square plates 57 move, the round pin 56 slides inside the second through groove 58 on the surface of the square plate 57 and passes through The round rod 55 drives the piston 53 to move upward synchronously, releasing the blocking effect of the piston 53 on the oil outlet pipe 52. At this time, the lubricating oil in the oil tank 4 flows into the liquid inlet groove 51 through the oil outlet pipe 52 under the action of gravity, and penetrates into the bearing 19 through the liquid inlet groove 51 to lubricate the bearing 19; when the hollow block 65 moves to the convex part of the surface of the cross plate 66 under the cooperation between the above structures, the hollow block 65 drives the T-shaped block 68 to move downward synchronously, releasing the interference effect of the T-shaped block 68 on the push block 63. At this time, the side plate 60 drives the two square plates 57 to move in the opposite direction and reset under the reset action of the two tension springs 61. The second through groove 58 on the surface of the square plate 57 and the round pin 56 are used again to push the piston 53 to move toward the inside of the oil outlet pipe 52, blocking the oil outlet pipe 52 and preventing the lubricating oil from flowing for a long time and wasting.

[0048] When the motor is turned off, the dustproof sheet 26 blocks the heat dissipation slot 21 again. At the same time, the hollow block 65 drives the hollow block 65 to move synchronously under the cooperation between the above structures. When the T-shaped block 68 on the top of the hollow block 65 contacts the push block 63, the T-shaped block 68 moves into the interior of the hollow slot 67 under the interference of the push block 63 and squeezes the second spring 69, releasing the interference with the push block 63, allowing the hollow block 65 to return to its original position, preparing for adding lubricating oil to the bearing 19 when the motor is turned on next time.

[0049] The present invention is provided with an automatic lubrication mechanism 5, which can automatically add lubricating oil to the bearing 19 when the auxiliary heat dissipation mechanism 2 is in use, thereby effectively ensuring the normal use of the bearing 19, improving the convenience of adding lubricating oil to the bearing 19 during maintenance, reducing the wear of the bearing 19 during the use of the motor, extending the service life of the motor bearing 19, and further increasing the practicality of the motor.

[0050] The present invention also provides a motor rotor, which is used in the motor described above.
