An environmental controller, a converter end device, and a resistance meter are also provided in the water-cooled motor housing.

A small gap space design is adopted between the rotor and the stator magnetic plates inside the generator of the present invention, which effectively improves the power generation efficiency and stability. If heat accumulation occurs unexpectedly between the rotor and the stator magnetic plates, the stator magnetic plates will increase the distance between the stator magnetic plates and the rotor by moving, so that the heat accumulated between the rotor and the stator magnetic plates can be quickly dissipated, avoiding the aggravation of heat accumulation and endangering the operation safety of the generator.

Description

Technical Field

[0001] The present invention relates to the technical field of power take-off generators, and in particular to a power take-off generator capable of maintaining low clearance operation. Background Art

[0002] The vehicle power take-off and power generation system consists of a power take-off rectifier, drive unit, cooling system, energy storage battery, power converter, display and control panel, mounting bracket, connecting cables, piping, and other accessories. Applied to lightweight, highly mobile platform vehicles, the power take-off and power generation system extracts engine power from the front crankshaft of the engine. A belt drives the power take-off generator to generate power, which is then output to the rectifier. After connecting to the energy storage battery, it is converted to a power converter. This system provides stable power to the power supply at all speeds, both in driving and parking conditions, and is capable of providing short-term emergency power.

[0003] The power take-off generator adopts a low clearance design with a small gap between the stator and rotor. This can significantly reduce the magnetic resistance, allowing the main magnetic flux to pass through the rotor conductor more efficiently, reducing the excitation current and copper loss, thereby improving the power factor. It can also enhance the electromagnetic coupling between the stator and rotor, reduce leakage magnetic loss, ensure that more magnetic flux is used for actual work, and increase the output power of the motor. However, the small gap will prevent the heat between the stator and rotor from dissipating quickly. As the generator is used for a longer time, the internal coil winding gradually ages, and the problem of heat accumulation gradually becomes apparent. The space for heat dissipation can be increased by periodically widening the gap between the stator and rotor to avoid the problem of heat accumulation in the gap. In addition, the rotor may rub against the stator due to slight vibrations, which can also be eliminated by increasing the gap. For this reason, the present invention provides a power take-off generator that can maintain low clearance operation. Summary of the Invention

DETAILED DESCRIPTION

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0049] The ring cylinder frame 11 is arranged on one end of the rotor 2 and is fixed on the water-cooled motor housing 1 . The ring cylinder frame 11 is fixedly connected to the limiting seat 9 , and the ring cylinder frame 11 limits and supports the unit shaft 12 .

[0050] Multiple unit shafts 12 are evenly arranged on the ring cylinder frame 11. The unit shafts 12 are movably sleeved in the through holes opened on the ring cylinder frame 11. The ends of the unit shafts 12 are engaged with the bevel gear fixed at the end of the unit screw 10 through the fixed bevel gear.

[0051] refer to Figure 7 It is understood that the converter 5 includes:

[0052] A circulating pendulum 13 that establishes transmission with all unit shafts 12, and a pressing tool 14 for driving the circulating pendulum 13 to rotate back and forth, the pressing tool 14 establishing transmission with the motor shaft 4;

[0053] An L-shaped end frame 15 is fixed at one end to the ring drum frame 11 , and the L-shaped end frame 15 supports the circulation pendulum 13 and the hair pressing device 14 at the same time.

[0054] refer to Figure 8 It is understood that the resistance measuring device 7 includes:

[0055] A plurality of axial modules 16 are fixedly provided around one end of the rotor 2, and a V-shaped spring piece 17 is in contact with one side of each axial module 16;

[0056] A wheel frame 18 is fixedly sleeved on the motor shaft 4, and a plurality of rollers 19 are evenly arranged on the wheel frame 18. The V-shaped spring piece 17 is fixed on the wheel frame 18, and each roller 19 pushes a corresponding axial module 16;

[0057] The ring slide 20 is arranged on the outside of the motor shaft 4, and the ring slide 20 is connected to the axial module 16, and the ring slide 20 and the circulating pendulum 13 establish transmission.

[0058] refer to Figure 9 It is understood that the axial module 16 includes a seat box 23 fixedly mounted on the rotor 2, a telescopic plate 21 slidably inserted into a square groove provided on the seat box 23, and a pullback spring 22 fixedly connected to the telescopic plate 21 at one end, and the other end of the pullback spring 22 is fixed on the seat box 23.

[0059] The telescopic plate 21 is fixedly connected to the ring slide 20. A bevel groove is provided on the telescopic plate 21. The roller 19 pushes the bevel on the telescopic plate 21 to extend the telescopic plate 21 from the seat box 23. Each side of the seat box 23 contacts a V-shaped spring piece 17.

[0060] During the operation of the generator of the present invention, the motor shaft 4 does not directly drive the rotor 2 to rotate, but the motor shaft 4 drives the wheel frame 18 to rotate synchronously, and the wheel frame 18 drives multiple V-shaped springs 17 arranged in a circle to move, and each V-shaped spring 17 pushes a corresponding seat box 23, and the seat box 23 is fixed on the rotor 2. In this way, the rotation of the rotor 2 is controlled by pushing. Under normal circumstances, the V-shaped spring 17 maintains a full shape. If the rotor 2 rotates, due to its own unexpected slight vibration, contact friction occurs between the rotating rotor 2 and the stationary stator magnetic plate 3, and the speed of the obstructed rotor 2 decreases, while the speed of the wheel frame 18 remains unchanged under the drive of the motor shaft 4, and then the V-shaped spring 17 is compressed, and the roller 19 installed on the wheel frame 18 moves relative to the telescopic plate 21, that is, Figure 9 The roller 19 in the middle swings to the right, and the roller 19 pushes the telescopic plate 21, and the telescopic plate 21 extends from the seat box 23, thereby causing the ring slide 20 to move axially. The movement of the ring slide 20 triggers the unlocking of the internal part of the circulating pendulum 13.

[0061] refer to Figure 12 It is understood that the circulating pendulum 13 includes a back frame 25 and a C-shaped rail body 24 fixed at one end of the back frame 25, a cylinder is fixed on the L-shaped end frame 15, the motor shaft 4 passes through the inside of the cylinder on the L-shaped end frame 15, and the other end of the back frame 25 is clamped into the ring groove opened on the outer wall of the cylinder of the L-shaped end frame 15 by setting a ring cylinder.

[0062] The circulating ornament 13 also includes an outer ring gear 28, an L-shaped clamping body 26 for locking the outer ring gear 28, and an annular spring 27 arranged inside the C-shaped rail body 24. The inner edge of the outer ring gear 28 is locked into the C-shaped slide groove provided on the C-shaped rail body 24. One end of the annular spring 27 is fixed to the arc frame provided on the back plate frame 25, and the other end of the annular spring 27 is fixed to the outer ring gear 28.

[0063] The back panel frame 25 is provided with a horizontal prism on the arc frame to slide through the prism hole opened in the middle of the L-shaped card body 26. One end of the L-shaped card body 26 is provided with a protrusion to be clamped into the square groove opened on the outer ring gear 28, and the L-shaped card body 26 is intercepted by one end of the C-shaped rail body 24. The other end of the L-shaped card body 26 is clamped with the local outer edge of the ring slide 20 by providing an arc-shaped recess.

[0064] The gap between the rotor 2 and the stator magnetic plate 3 is small. If the rotor 2 rotates slightly unexpectedly, the rotor 2 will contact and rub against the stator magnetic plate 3. The stator magnetic plate 3 will automatically move away from the rotor 2 to avoid aggravation of the friction problem. As mentioned before, the friction problem will cause the rotor 2 to rotate later than the motor shaft 4, triggering the axial movement of the ring slide 20, which drives the ring slide 20 to rotate. Figure 12The L-shaped card body 26 in the middle, after the L-shaped card body 26 is translated, the protrusion on the L-shaped card body 26 no longer blocks the outer ring gear 28, so that the outer ring gear 28 will rotate relative to the C-shaped rail body 24, and the rotation power is provided by the annular spring 27, that is, the annular spring 27 releases power to drive the outer ring gear 28 to rotate. During the process of the outer ring gear 28 rotating at a small angle, the outer ring gear 28 transmits all the unit shafts 12, and then the unit shaft 12 transmits the unit screw 10. The rotation of the unit screw 10 causes the arc plate box 8 to move, and the arc plate box 8 drives the stator magnetic plate 3. The stator magnetic plate 3 gradually moves away from the rotor 2, and the gap space between the stator magnetic plate 3 and the rotor 2 increases, eliminating the friction problem between the stator magnetic plate 3 and the rotor 2. In addition, after the gap space between the stator magnetic plate 3 and the rotor 2 increases, the occurrence of heat accumulation problems is further prevented.

[0065] The hair press 14 includes a transverse axis group 29 that establishes a transmission with the motor shaft 4 at one end, a spring group 30 that is driven by the other end of the transverse axis group 29, a swing plate group 31 that connects the spring group 30 and the back plate frame 25, and a first plate frame 32 fixed on the L-shaped end frame 15. The swing plate group 31 includes a transverse punch plate 34, a rocking plate 35 hinged at one end of the transverse punch plate 34, and a cubic tube 33 hinged at the other end of the transverse punch plate 34. The partial plate body on the back plate frame 25 slides through the inside of the cubic tube 33, and the transverse punch plate 34 slides through the plate hole opened on the L-shaped end frame 15.

[0066] The transverse axis group 29 includes a lead-out shaft 36, a head shaft 37 and a tail worm 40 that are limited and supported by the first plate frame 32. The transverse axis group 29 also includes a bridge prism 39 for overlapping transmission between the tail worm 40 and the head shaft 37, and an adjustment seat 38 that supports the bridge prism 39. The first plate frame 32 is provided with a flat plate to slide through the plate hole opened on the adjustment seat 38. The middle part of the bridge prism 39 is movably sleeved in the through hole opened on the adjustment seat 38 by providing an axis body. One end of the bridge prism 39 is slidably inserted into the prism groove opened on the tail worm 40. A prism groove for the bridge prism 39 to dock and insert is reserved on the head shaft 37 at the other end of the bridge prism 39. One end of the lead-out shaft 36 is passed through A bevel gear is provided to mesh with the bevel gear provided at the end of the head shaft 37 for transmission, and the other end of the lead-out shaft 36 is meshed with the outer gear ring fixed on the motor shaft 4 by providing a gear. The lead-out shaft 36, the head shaft 37 and the tail worm 40 are respectively movably sleeved in different through holes opened on the first plate frame 32. A temperature sensor in the prior art is provided in the water-cooled motor housing 1 to detect the temperature of the gap space between the rotor 2 and the stator magnetic plate 3. If the temperature is too high, the temperature sensor sends the temperature information to the main terminal of the generator, and then controls the driver provided inside the water-cooled motor housing 1. The driver is a prior art device, and the driver is connected to the adjustment seat 38, and then the driver controls Figure 14The adjusting seat 38 in the middle moves horizontally to the left, and the adjusting seat 38 drives the bridge prism 39, and the bridge prism 39 is inserted into the head shaft 37 to the left, so that a complete transmission path is established in the horizontal shaft group 29.

[0067] The spring group 30 includes a circular groove shell 42 hinged to the swing plate 35, a round spring 44 connected to the inside of the circular groove shell 42, a triggering shaft 43 fixedly connected at one end to the middle of the circular spring 44, and a strip plate 45 movably sleeved with the triggering shaft 43, and a J-shaped spring clip 41 fixed to the first plate frame 32. The triggering shaft 43 is also movably sleeved in a circular hole opened in the first plate frame 32. The other end of the triggering shaft 43 is engaged with the helical teeth on the tail worm 40 through a fixed gear. The J-shaped spring clip 41 is stuck in the arc groove opened on the outer wall of the circular groove shell 42. The end of the strip plate 45 is fixed to the circular groove shell 42. The outer end of the round spring 44 is fixed to the circular groove shell 42, and the inner end is fixed to the triggering shaft 43. The shaft body is fixed on the back of the circular groove shell 42, and the shaft body is movably sleeved in the through hole opened in the swing plate 35.

[0068] When there is no contact friction between the rotor 2 and the stator magnetic plate 3, if heat accumulates between the rotor 2 and the stator magnetic plate 3, the problem of heat accumulation has multiple causes, such as partial coil winding failure or aging over time. As mentioned before, after the heat accumulation problem is detected by the temperature sensor, it will eventually cause transmission to be established inside the cross-axis group 29, so that the rotating motor shaft 4 drives the lead-out shaft 36, and then drives the bridge prism 39 through the head shaft 37, and then drives the pressure shaft 43 through the tail worm 40. The pressure shaft 43 gradually contracts and accumulates force. When the accumulated pressure is sufficient, J The clamping state between the J-shaped spring piece 41 and the circular groove shell 42 is broken, which will cause the circular groove shell 42 to rotate one circle. After one full circle, the circular groove shell 42 is re-positioned by the J-shaped spring piece 41. The process of the circular groove shell 42 rotating one full circle corresponds to a cyclic change in the distance between the rotor 2 and the stator magnetic plate 3, that is, the stator magnetic plate 3 gradually moves away from the rotor 2, and the heat accumulated between the stator magnetic plate 3 and the rotor 2 is dissipated. Then the stator magnetic plate 3 approaches the rotor 2 again. During this process, the coil winding on the rotor 2 will still cut the magnetic lines of force, and the generator can still generate electricity.

[0069] The specific transmission process of the stator magnetic plate 3 moving away from the rotor 2 and then returning to its original position: the circular groove shell 42 rotates one circle, driving the rocking plate 35 in the process, causing the transverse plate 34 to slide back and forth, and then driving the back plate frame 25 to swing through the cubic tube 33. The swing of the back plate frame 25 causes the entire circulating pendulum 13 to rotate back and forth. At this time, the L-shaped card body 26 is in the state of locking the outer ring gear 28. The outer ring gear 28 drives all the unit shafts 12 during the reciprocating rotation. As mentioned earlier, the rotation of the unit shaft 12 corresponds to the final movement of the arc plate box 8, and the arc plate box 8 drives the stator magnetic plate 3. In this way, the stator magnetic plate 3 gradually moves away from the rotor 2, and then the stator magnetic plate 3 gradually returns to its original position close to the rotor 2. There is a period of increased gap space between the rotor 2 and the stator magnetic plate 3, and the heat accumulated inside is dissipated during this period.
