Description

Technical Field

[0001] This invention relates to the field of generator technology, specifically to a permanent magnet rotor generator for vehicles. Background Technology

[0002] There are several reasons why an electric motor might overheat during operation: Harsh working environment, such as exposure to direct sunlight or poor ventilation leading to inadequate heat dissipation; excessively high power supply voltage increasing the magnetic flux density of the iron core and increasing iron losses, while excessively low voltage reduces motor efficiency and generates more heat; overloading, such as a tight transmission mechanism, jammed bearings, or dry lubrication, can all cause overloading and motor overheating; mechanical faults such as worn bearings, improper rotor-stator clearance, and fan malfunctions can increase friction, leading to overheating; winding problems, such as short circuits, inter-turn short circuits, and phase-to-phase short circuits, can increase current and cause overheating; unstable power supply voltage, where voltage fluctuations cause unstable motor current, resulting in overheating; and poor heat dissipation, such as blocked internal cooling devices or excessively high ambient temperatures, preventing effective heat dissipation from the motor's internal components.

[0003] The windings of an electric motor generate heat during operation, and the temperature of the motor windings is usually higher than that of the iron core. This is due to the Joule heating generated by the winding impedance and current. Based on the goal of solving the vibration problem caused by improper gap between the motor rotor and stator, and the research and development of heat dissipation for stator winding power transmission, this invention provides a permanent magnet rotor generator for vehicles. Summary of the Invention

[0011] The lubrication mechanism includes a grease box fixed on the control cylinder, a push plate in which the piston slides, a lead screw with a threaded hole through the push plate, a travel gear fixed on the lead screw, a lap joint for transmission on one side of the travel gear, and an oil delivery pipe with one end fixedly connected to the bottom of the grease box.

[0012] The reinforcement device includes an integrated shaft, a row of non-rotating cylinders fixed on the integrated shaft, a limiting short plate supporting the integrated shaft, and a T-shaped flat nozzle with lubricant applied to one side of the non-rotating cylinder.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the technical solutions 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.

[0033] Please see Figures 1 to 13 This invention provides a technical solution: a permanent magnet rotor generator for vehicles, comprising a motor body 1, a rotating permanent magnet rotor 2 disposed within the motor body 1, and a stationary winding stator 3 surrounding the permanent magnet rotor 2. The permanent magnet rotor 2 includes a motor shaft 4, a control cylinder 5 fixedly sleeved on the motor shaft 4, and a plurality of uniformly distributed permanent magnet plates 6 outside the control cylinder 5.

[0034] refer to Figure 5 The actuation device 13 includes an L-shaped control frame 16 with one end fixed to the motor shaft 4, a roller assembly 15 supported at the other end of the L-shaped control frame 16, a pressure spring 17 that pushes the roller assembly 15, and a lap worm gear 14 that establishes a transmission between the roller assembly 15 and the pressure relief device 9. The lap worm gear 14 is movably sleeved in a round hole opened on the L-shaped control frame 16.

[0035] refer to Figure 5The roller assembly 15 includes a T-shaped plate 18 that slides through a square hole in an L-shaped control frame 16 at one end, a journal shaft 19 and a roller shaft 20 supported at the other end of the T-shaped plate 18, and a rubber wheel 21 fixed at one end of the roller shaft 20. The other end of the roller shaft 20 is connected to the bevel gear fixed at one end of the journal shaft 19 via a fixed bevel gear. The other end of the journal shaft 19 is connected to the gear fixed on the worm gear 14 via a fixed gear. One end of the pressure spring 17 is fixed on the T-shaped plate 18 and the other end is fixed on the L-shaped control frame 16. The rubber wheel 21 is in contact with the thin inner wall of the winding stator 3. The journal shaft 19 and the roller shaft 20 are respectively movably sleeved in two through holes in the T-shaped plate 18.

[0036] refer to Figure 6 Understandably, the pressure relief device 9 includes an internal gear ring 27, an annular spring 24 with an outer fixed sleeve of the internal gear ring 27, an outer gear ring 22 with an outer fixed sleeve of the annular spring 24, and multiple uniformly arranged unit shafts 26 that drive internally within the internal gear ring 27. The unit shafts 26 are connected to the internal gear ring 27 by a fixed long shaft gear 51, and the helical teeth on the worm gear 14 are connected to the outer gear ring 22 by meshing.

[0037] The pressure relief device 9 also includes a unit frame 23 and a C-shaped spring piece 25. Multiple unit frames 23 are evenly arranged around the outer gear ring 22 and the inner gear ring 27. One end of the unit frame 23 is fixed to the motor shaft 4. The unit frame 23 is fitted into an annular groove on the inner side wall of the outer gear ring 22 by means of a first arc plate. The unit frame 23 is fitted into an annular groove on the outer side wall of the inner gear ring 27 by means of a second arc plate. The unit shaft 26 is movably sleeved in the through hole on the unit frame 23. The C-shaped spring piece 25 is fixed on the L-shaped control frame 16. One side of the inner gear ring 27 is engaged with the C-shaped spring piece 25 by means of a fixing protrusion.

[0038] refer to Figure 8Understanding the air ring assembly 10, it includes a rotating ring plate 28, a fixed rubber ring box 29 inside the rotating ring plate 28, multiple evenly arranged air ducts 30 connected inside the rubber ring box 29, a fan 32 installed in the air duct 30, and a fan shaft 31 fixed in the middle of the fan 32. The air duct 30 is fixed on a horizontal plate on the unit frame 23, and the fan shaft 31 is movably sleeved in a through hole opened in the horizontal plate. One end of the fan shaft 31 is connected to a bevel gear fixed on the unit shaft 26 through a fixed bevel gear for transmission. The air diffuser box 11 is a ring shell with a concave cross-section. The 11 is movably fitted into the annular groove on the outer wall of the rotating ring plate 28. The rubber ring box 29 is an annular shell with an outward concave cross section. Multiple through holes are provided on the rotating ring plate 28 to connect the air diffuser box 11 and the rubber ring box 29. The air duct 30 fixed on the rubber ring box 29 drives the rubber ring box 29 and the rotating ring plate 28 to rotate synchronously through the circumferential motion. The rubber ring box 29 can deform slightly at any time to buffer the radial vibration that may occur unexpectedly during the rotation of the permanent magnet rotor 2, and ensure that the ventilation path exists between the air duct 30, the rubber ring box 29, the air diffuser box 11 and the L-shaped flat tube 12.

[0039] During the rotation of the motor shaft 4, the driving device 13 rotates in a circular motion, accompanying the rotation of the motor shaft 4. The rotating rubber wheel 21 contacts the inner wall of the stationary winding stator 3 thin cylinder, causing the rubber wheel 21 to continuously rotate. Subsequently, it drives the journal shaft 19 through the roller shaft 20, and then drives the outer gear ring 22 to rotate through the worm gear 14, causing the annular spring 24 to contract and store power. After the annular spring 24 is fully charged, the outer gear ring 22 continues to drive, and the protrusion on the inner gear ring 27 will break through the interception and locking position of the C-shaped spring 25, thus allowing the inner gear ring 27 to rotate quickly for one revolution. After the inner gear ring 27 has rotated for one revolution, the protrusion on the inner gear ring 27 is intercepted again by the C-shaped spring 25, and the annular spring 24 begins the next round of power storage. Therefore, the inner gear ring 27 rotates intermittently, and during the rotation of the inner gear ring 27, it drives all The unit shaft 26 rotates, and then the fan shaft 31 drives the fan 32 to rotate rapidly multiple times. Outside air is drawn into the air duct 30, and then injected into the air distribution box 11 through the rubber ring box 29. It is then dispersed and discharged through multiple L-shaped flat tubes 12. The L-shaped flat tubes 12 blow air into the gap between two adjacent windings on the winding stator 3 to blow away the heat emitted by the winding. In summary, when the motor shaft 4 rotates, the rubber wheel 21 contacts and rotates to collect weak power, which is then concentrated and released through the annular spring 24, thereby providing strong power for the fan 32 to rotate. In this way, the air ring group 10 provides strong ventilation, and the L-shaped flat tubes 12 blow out strong airflow at regular intervals to cool the winding stator 3. The air flowing through the air duct 30 can be outside air of the motor or low-temperature air pre-generated by the existing water cooling mechanism.

[0040] The lubrication mechanism 8 includes a grease box 40 fixed on the control cylinder 5, a push plate 39 in which the piston slides in the grease box 40, a lead screw 42 through which a threaded hole is opened on the push plate 39, a stroke gear 41 fixedly sleeved on the lead screw 42, a lap joint 37 that drives on one side of the stroke gear 41, and an oil delivery pipe 38 whose one end is fixedly connected to the bottom of the grease box 40. The grease box 40 is a square groove shell that stores lubricant inside.

[0041] The reinforcement device 7 includes an integrated shaft 33, a row of non-rotating cylinders 35 fixedly sleeved on the integrated shaft 33, a limiting short plate 34 supporting the integrated shaft 33, and a T-shaped flat nozzle 36 with lubricant applied to one side of the non-rotating cylinders 35. One end of the T-shaped flat nozzle 36 is fixedly connected to the oil delivery bend pipe 38. The limiting short plate 34 is fixed on the control cylinder 5. The integrated shaft 33 is movably sleeved in the through hole opened on the limiting short plate 34. A through T-shaped plate hole is opened inside the T-shaped flat nozzle 36.

[0042] The overlapping assembly 37 includes an L-shaped bracket 44 with one end fixed to the grease box 40, a T-shaped brake plate 45 with one end sliding through a plate hole in the L-shaped bracket 44, a V-shaped block 43 fixed on the T-shaped brake plate 45, an inner slide bar 47 supported on the T-shaped brake plate 45, a spring 49 sleeved on the inner slide bar 47, and a double-acting gear 50 fixed at one end of the inner slide bar 47. The inner slide bar 47 slides through a column hole in the T-shaped brake plate 45. The V-shaped block 43 is engaged in a V-groove at one end of the integrated shaft 33. The lead screw 42 is movably sleeved in the column hole in the L-shaped bracket 44. The double-acting gear 50 contacts and meshes with a long shaft gear 51 fixed on the unit shaft 26 through axial movement. The spring 49 is supported between the double-acting gear 50 and the T-shaped brake plate 45. An intercepting ring is also fixed on the inner slide bar 47 to limit the axial movement range of the double-acting gear 50.

[0043] The lap assembly 37 also includes a pull-back spring 46 and an actuating shaft 48. One end of the pull-back spring 46 is fixed on the L-shaped fixed frame 44, and the other end is fixed on the T-shaped brake plate 45. The actuating shaft 48 is movably sleeved in the column hole opened on the L-shaped fixed frame 44. One end of the actuating shaft 48 is connected to the stroke gear 41 through a fixed gear, and the other end of the actuating shaft 48 is connected to the double-acting gear 50 through a fixed gear.

[0044] The reinforcing device 7 is installed on the control cylinder 5. Rotation of the control cylinder 5 causes the reinforcing device 7 to rotate. The non-rotating cylinder 35 and the inner wall of the thin cylinder of the winding stator 3 slide out of alignment. The non-rotating cylinder 35 does not rotate because the V-block 43 engages the integrated shaft 33, thus preventing the integrated shaft 33 and the non-rotating cylinder 35 from rotating. The outer wall of the non-rotating cylinder 35 is coated with grease, allowing for smooth sliding out of alignment between the inner wall of the thin cylinder of the winding stator 3 and the non-rotating cylinder 35. The reinforcing device 7 assists in limiting the control cylinder 5 by being placed between the control cylinder 5 and the winding stator 3, reducing the probability of vibration of the rotating control cylinder 5. However, the grease on the outer wall of the non-rotating cylinder 35 is consumed by friction and needs to be replenished promptly. This invention uses a lubrication mechanism 8 to automatically ensure the supply of grease. Specifically, when the surface of the non-rotating cylinder 35 becomes dry, the sliding out of alignment between the thin cylinder of the winding stator 3 and the non-rotating cylinder 35 will cause the non-rotating cylinder... When the shaft 35 rotates, the integrated shaft 33 will forcefully break through the V-block 43's locking position. The V-block 43 is pushed back and moved, causing the T-shaped brake plate 45 to move horizontally. This, in turn, pushes the double-acting gear 50 through the spring 49. The double-acting gear 50 moves axially and establishes a transmission with the long shaft gear 51. This provides the power to deliver the grease. Specifically, the unit shaft 26 rotates intermittently, and then the long shaft gear 51 drives the double-acting gear 50 to rotate. Next, the drive shaft 48 drives the stroke gear 41, causing the lead screw 42 to rotate slowly. The push plate 39, which is screwed to the lead screw 42, is pushed into the grease box 40, squeezing out the grease in the grease box 40. Then, it diffuses through the oil delivery pipe 38 into a row of T-shaped flat nozzles 36. The grease discharged from the T-shaped flat nozzles 36 is applied to the rotating non-rotating cylinder 35, thus regenerating a layer of lubricating oil film on the outer wall of the non-rotating cylinder 35.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
