Description

Technical Field

[0001] The present invention relates to the field of aviation technology, and in particular to a new energy aircraft variable pitch propeller with real-time communication. Background Art

[0002] The propeller is a key component of an aircraft. It is used to convert the rotation of the aircraft's motor or engine shaft into thrust, thereby providing the aircraft with power to fly. The propeller's variable pitch control device controls the real-time state of the propeller according to the real-time working state of the engine and the aircraft. By controlling the deflection angle of the propeller, the propeller's flight states such as climbing, rotating and moving can be better controlled, so that the propeller can work at the optimal blade angle to achieve the best working efficiency of the propeller.

[0003] When adjusting the existing propeller pitch change device, a motor is generally used to control the deflection angle of the propeller. However, when the motor is powered off after the adjustment is completed, the magnetic field inside the motor changes, generating an induced electromotive force in the opposite direction of the original rotation. This induced electromotive force will drive the motor to rotate in the opposite direction for a short time, causing the motor to rotate, resulting in a difference between the adjustment angle of the propeller and the expected angle, thereby affecting the overall flight state of the aircraft and the safety and stability during flight.

The sealing cylinder 111 is composed of multiple groups of slip rings that are slidably connected to each other. While not affecting the rotation of the toothed disc 2 107 and the up and down sliding of the adjusting block 103, the sealing effect on the threaded column 108 is maintained to prevent oil leakage.

[0033] Furthermore, the portion of the slider 115 extending to the outside of the turntable 109 is provided with an inclined surface matching with the protrusion 117 .

[0034] Specifically, there are two groups of self-locking mechanisms which are symmetrically arranged at the top and bottom of the inner side of the mounting frame 100.

[0035] Reference Figure 3-9The lubrication mechanism includes a pneumatic chamber 302 disposed inside the adjustment block 103 and a lubrication chamber 301 on the surface of the adjustment block 103. The interior of the lubrication chamber 301 is connected with a piston 304 through a spring sleeve. The lubrication chamber 301 and the pneumatic chamber 302 form a set of lubrication components. The lubrication components are symmetrically distributed along the upper and lower sides of the adjustment block 103, and multiple groups of lubrication components are distributed in a ring along the center of the adjustment block 103. The mounting frame 100 is provided with an air pipe 112, and one end of the air pipe 112 extends to the top of the tooth plate 106 and between the mounting frame 100. The other end of the air pipe 112 extends to the interior of the pneumatic cabin 1 302, a piston 2 310 is arranged inside the pneumatic cabin 1 302, a spring is arranged between the piston 2 310 and the pneumatic cabin 1 302, a slide 307 is slidably connected between the pneumatic cabin 1 302 and the lubricating cabin 301, a channel 1 306 is arranged at the bottom of the lubricating cabin 301, a channel 2 308 matching with the channel 1 306 is arranged on the surface of the slide 307, a magnet 4 309 matching with the slide 307 is arranged on the top of the pneumatic cabin 1 302, and the bottom of the slide 307 A stopper 316 is provided to match the second piston 310, a nozzle 305 is provided on the side of the lubrication chamber 301 facing the threaded column 108, an oil storage chamber 126 is provided inside the mounting frame 100, an oil supply pipe 127 is provided inside the mounting frame 100 to connect the oil storage chamber 126 with the lubrication chamber 301, a one-way valve is provided inside the oil supply pipe 127, and a reset assembly is provided in the pneumatic chamber 1 302 close to the top of the regulating block 103; it should be noted that a through hole is provided on the side wall of the lubrication chamber 301, and a through hole is provided between the channel 1 306 and the channel 2 308. The connection allows the interior of the lubrication cabin 301 to be rapidly inflated until the piston 1 304 is pushed to squeeze the lubricating oil inside the lubrication cabin 301 and spray it out through the nozzle 305. After the slide 307 is reset so that the channel 2 308 is disconnected from the channel 1 306, the gas inside the lubrication cabin 301 that has lost its gas supply can be slowly discharged through the through holes on the side wall of the lubrication cabin 301. At the same time, the piston 1 304 can be slowly reset under the action of the spring connected to the lubrication cabin 301, and the oil inside the lubrication cabin 301 can be absorbed through the oil supply pipe 127 to ensure subsequent circulation operation.

[0036] Reference Figure 7-9 The reset component includes a pneumatic cabin 2 303, and a pneumatic cabin 2 303 is arranged on the side wall of the pneumatic cabin 1 302 close to the top of the adjustment block 103.

It should be noted that when the piston two 310 is inflated to drive the sleeve 311 to move slowly, the piston push rod 312 is slowly extended under the action of the spring force between the piston push rod 312 and the sleeve 311. When the piston two 310 is quickly reset, the air between the sleeve 311 and the piston push rod 312 is difficult to be quickly discharged through the through hole on the side wall of the sleeve 311, so that when the piston two 310 is reset, it can push the magnetic block five 313 to move toward the direction of the piston three 315.

[0038] It should be noted that the air pipe 112 is connected to the pneumatic cabin 1 302 near the top of the adjustment block 103, and the mounting frame 100 is provided with an air pipe 125, one end of the air pipe 125 is connected to the gap between the bottom of the toothed disc 4 124 and the mounting frame 100, and the other end of the air pipe 125 is connected to the pneumatic cabin 1 302 near the bottom of the adjustment block 103, and the air pipe 125 is also connected to the interior of the pneumatic cabin 2 303.

[0039] The working process of the variable pitch propeller of the new energy aircraft with real-time communication is as follows:

[0040] When adjusting the blade 200 of the aircraft, after the motor 102 is powered on, the output end of the motor 102 drives the threaded column 108 to rotate, and the adjusting block 103 is driven to rise and fall in the vertical direction through the threaded transmission. When the adjusting block 103 moves, the relative sliding cooperation between the adjusting slot 104 and the eccentric sliding pin 205 drives the adjusting shaft 201 to rotate, and then drives the blade 200 to rotate, so as to adjust the blade 200. When the adjusting shaft 201 rotates, the incomplete gear 204 rotates synchronously, thereby driving the transmission gear 203 to rotate, which can drive the detection of the angle sensor 202. By measuring the rotation of the shaft, the rotation angle of the blade 200 can be input into the angle sensor 202 through the transmission of the adjustment shaft 201, the incomplete gear 204, and the transmission gear 203, so as to realize the real-time monitoring of the angle of the blade 200. At the same time, through the design of the electric slip ring 101, when the mounting frame 100 rotates, the contact and cooperation between the brush inside the electric slip ring 101 and the conductive ring can be realized, so as to realize the circuit path and the real-time interactive transmission of information, so as to realize the continuous information transmission of the electric slip ring 101 to monitor and control the components during the operation of the aircraft.

[0041] During the process of adjusting the blade 200, after the motor 102 is started, the electromagnet 113 is energized synchronously, and the toothed disc 106 and the toothed disc 4 124 are respectively adsorbed to the top and bottom of the inner side of the mounting frame 100, so that the toothed disc 106 and the toothed disc 2 107 are disengaged, and the toothed disc 4 124 and the toothed disc 3 123 are disengaged at the same time. When the threaded column 108 further rotates, driving the adjustment block 103 to move upward, the rotating disk 109 rotates in a direction so that the right-angled side of the slider 115 moves toward the direction of the protrusion 117, and the right-angled side of the slider 115 drives the protrusion 117 and then drives the slip ring 116 synchronously. When the slip ring 116 rotates, the contact piece 118 can be periodically contacted with the contact piece 2 122, and the electromagnet 113 at the top of the adjustment slot 104 is kept in a power-off and non-magnetic state by continuous rotation, so that the toothed disc 106 moves downward under the elastic force of the spring between the light rod 105 and the toothed disc 2 107 and keeps engaged with the toothed disc 2 107, and the rotation direction satisfies that when the toothed disc 2 107 and the toothed disc 106 move relative to each other, the edge of the toothed disc 2 107 and the toothed disc 106 surface close to each other is an inclined surface, so the toothed disc 2 107 can push the toothed disc 106 to do a reciprocating motion in the vertical direction through the cooperation between the teeth. Once the screw After the threaded column 108 stops rotating, and when the motor 102 stops adjusting and rotates due to the potential difference after power is cut off, the relative rotation direction of the toothed disc 2 107 and the toothed disc 1 106 is reversed through the engagement of the toothed disc 1 107 and the toothed disc 1 106. At this time, since the edges of the teeth on the surfaces of the toothed disc 1 106 and the toothed disc 2 107 that are close to each other are right-angled edges, the toothed disc 1 106 and the toothed disc 2 107 cannot rotate in the opposite direction, and the threaded column 108 is automatically locked after power is cut off, which effectively reduces the adjustment error, improves the precision and accuracy of the adjustment of the blade 200, and improves the consistency of the adjustment of the blade 200 with the expectation. Moreover, after the motor 102 is powered off, the electromagnet 113 is powered off synchronously. Under the action of the spring reset, the sprocket 106 is engaged with the sprocket 2 107, and the sprocket 3 123 is engaged with the sprocket 4 124. Through the opposite tooth bevel design of the sprocket 2 107 and the sprocket 3 123, the threaded column 108 will be blocked by one of the groups no matter which direction it rotates, thereby preventing the threaded column 108 from rotating in any direction, locking the threaded column 108, ensuring the limiting effect on the position of the adjustment block 103 and the angle of the blade 200, and thereby improving the angle stability of the blade 200 during normal operation.

[0042] It should be noted that the self-locking structure is symmetrically distributed along the upper and lower ends of the mounting frame 100. In the symmetrically distributed self-locking structure, the inclined surfaces of the teeth distributed on the second and third toothed discs 107 and 123 face opposite directions, and the first and fourth toothed discs 106 and 124 cooperate with the second and third toothed discs 107 and 123 respectively. Therefore, referring to the above technical scheme, when the adjustment block 103 is adjusted to move upward, the rotation direction of the threaded column 108 can make the toothed disc 3 123 and the fourth and fourth toothed discs 124 non-contact with each other under the cooperation of the electromagnet 113 and the magnet 1 114, and the light rod 105 and the toothed disc 1 106 remain engaged and can rotate in one direction. When the adjustment block 103 moves downward, since the rotation direction of the threaded column 108 is opposite, the toothed disc 3 123 and the fourth and fourth toothed discs 124 are engaged, and the toothed disc 1 106 and the second and third toothed discs 107 are not in contact.

[0043] It should be noted that in the self-locking structure, a turntable 109 is provided at the top and the bottom of the threaded column 108, and the inclined surfaces of the sliders 115 are designed in opposite directions, so that when one group of sliders 115 drives the corresponding slip ring 116 to rotate, the inclined surface design of the other group of sliders 115 is pushed and compressed inward each time it passes through the protrusion 117, and will not drive the corresponding slip ring 116.

[0044] It should be noted that the magnetic force cooperation between magnet three 121 and magnet two 119 causes a certain resistance when the slider 115 pushes the bump 117, and once the slip ring 116 is pushed to rotate, magnet three 121 and magnet two 119 are separated, and magnet two 119 quickly rotates under the magnetic attraction of the next group of magnets three 121 and cooperates with the next group of magnets three 121, thereby avoiding the contact piece 118 from maintaining contact with the contact piece two 122 for a long time due to the push of the slider 115.

[0045] During the adjustment process, when the adjusting block 103 moves upward by rotating the threaded column 108, the engagement of the second tooth plate 107 with the first tooth plate 106 can push the first tooth plate 106 to do reciprocating swinging motion in the vertical direction. When the first tooth plate 106 moves upward, the gas between the first tooth plate 106 and the mounting frame 100 can be pumped into the air pipe 112 through the one-way valve. When resetting, the external gas can be sucked into the gap between the first tooth plate 106 and the mounting frame 100 through the air hole inside the mounting frame 100. After the gas enters the air pipe 112, it enters the air pipe 112 close to the adjusting block 10 3, the inside of the pneumatic cabin 1 302 is filled with air, the piston 2 310 is pushed to move, and the spring between the piston 2 310 and the pneumatic cabin 1 302 is compressed until the piston 2 310 moves to contact the stopper 316 and pushes the slide 307 through the stopper 316, so that the slide 307 and the magnet 4 309 are close to and adsorbed. At this time, the channel 2 308 is connected with the channel 1 306, and the compressed gas in the pneumatic cabin 1 302 is compressed and pushed to the inside of the lubrication cabin 301 under the elastic force of the spring set on the side wall of the piston 2 310, so that The piston 1 304 moves to spray the oil between the piston 1 304 and the lubrication chamber 301 through the nozzle 305, and performs atomization spray lubrication on the contact part between the top of the adjusting block 103 and the threaded column 108. The lubricating oil lubricates the contact part between the threaded column 108 and the adjusting block 103 through the rotation of the threaded column 108 and the upward movement of the adjusting block 103, and moves downward due to gravity, so as to ensure the stable progress of the adjustment work. After the compressed gas inside the pneumatic chamber 1 302 enters the lubrication chamber 301, the internal pressure of the pneumatic chamber 1 302 is significantly reduced, and the piston 2 310 is on the side wall The piston 310 is reset under the elastic force of the spring. When the piston 310 is reset to contact the block 316 close to the channel 2 308, the block 316 can further push the slide 307 to slide in the opposite direction, so that the slide 307 contacts and attracts the magnet 4 309 on the other side, so that the slide 307 moves to the channel 2 308 and disconnects from the channel 1 306. The gas inside the lubrication compartment 301 is discharged through the through hole on the side wall of the lubrication compartment 301 to restore the balance. At the same time, the movement and reset of the piston 1 304 can absorb the oil through the oil supply pipe 127 to realize the circulation of the lubrication work.

[0046] It should be noted that two groups of blocks 316 are provided at the bottom of the slide 307, and two groups of magnets 309 are also provided on both sides of the slide 307. Both ends of the slide 307 are magnets and cooperate with the magnets 309. When the slide 307 moves to one side, the slide 307 can be adsorbed and positioned through the magnetic force between the magnets 309 and the slide 307.

[0047] When the adjustment block 103 moves downward, the engagement of the toothed disc three 123 and the toothed disc four 124 can push the toothed disc four 124 to make a reciprocating swinging motion in the vertical direction. When the toothed disc four 124 moves downward, the gas between the toothed disc four 124 and the mounting frame 100 can be pumped into the air pipe two 125 through the one-way valve. After entering the air pipe two 125, the gas is divided into two groups. One group enters the piston two 310 close to the bottom of the adjustment block 103. According to the above working process, the lubricating oil is sprayed to lubricate the contact part between the bottom of the adjustment block 103 and the threaded column 108. As the adjustment block 103 moves downward, the contact part between the adjustment block 103 and the threaded column 108 is lubricated, and the other group of gas enters the inside of the pneumatic cabin two 303 through the air pipe two 125. , by inflating the inside of the pneumatic cabin 2 303 to increase the internal pressure of the pneumatic cabin 2 303, the piston 315 is pushed to slide along the sliding shaft 314. When the piston 315 moves to the point where the U-shaped channel inside the piston 315 is in contact and connected with the H-shaped pipe of the sliding shaft 314, the gas inside the pneumatic cabin 2 303 enters the inside of the pneumatic cabin 1 302 connected to the pneumatic cabin 2 303 through the H-shaped pipe of the sliding shaft 314, pushing the piston 2 310 to move. Further, through the above working process, the lubricating oil is sprayed to lubricate the contact part between the top of the adjusting block 103 and the threaded column 108. When the piston 2 310 is in the process of resetting, the air between the sleeve 311 and the piston push rod 312 is difficult to be quickly discharged through the through hole on the side wall of the sleeve 311, so that the piston 2 310 When the piston 303 is reset, the magnetic block 5 313 ​​can be pushed to move toward the piston 315, so that the piston 315 moves and is adsorbed by the magnetic block 5 313 ​​under the action of the air pressure inside the pneumatic cabin 2 303 and the magnetic force of the magnetic block 5 313. At the same time, through the movement of the piston 315, the U-shaped channel inside the piston 315 is no longer connected with the entrance of the H-shaped channel inside the sliding shaft 314 close to the air pipe 2 125, so that the gas inside the pneumatic cabin 2 303 will not enter the pneumatic cabin 1 302 through the H-shaped channel inside the sliding shaft 314, so that after the pneumatic cabin 1 302 connected to the pneumatic cabin 2 303 completes a pumping lubrication, the subsequent pneumatic cabin 2 303 will no longer supply power to the pneumatic cabin 1 302 to continue pumping gas for lubrication until the adjustment work stops. After the air is stopped, the air pipe 125 stops supplying air, and the pressurized gas is discharged through the air holes on the side wall of the pneumatic cabin 303, so that the air pressure inside the pneumatic cabin 303 is reduced. The loss of air pressure pushes the piston 315 to overcome the magnetic force with the magnetic block 5 313 ​​and reset under the elastic force of the spring. It should be noted that the exhaust speed of the air hole is slow, and the impact is small during continuous inflation, which can be regarded as a sealed state. When inflation is stopped, the internal gas can be slowly discharged through the air hole to achieve internal and external pressure balance. At the same time, the gas in the subsequent air pipe 125 will only enter the piston 310 close to the bottom of the adjusting block 103, and spray lubrication on the contact part of the bottom of the adjusting block 103 with the threaded column 108. Therefore, during the adjustment movement of the adjusting block 103, when the adjusting block 103 moves upward,The lubrication mechanism can automatically spray lubricate the contact part between the top of the adjustment block 103 and the threaded column 108, and lubricate the contact part between the adjustment block 103 and the threaded column 108 under the action of gravity, thereby reducing the wear and friction between the adjustment block 103 and the threaded column 108 during the relative movement, and improving the stability of the device operation and the accuracy of the adjustment work. When the adjustment block 103 moves downward, the lubrication mechanism can automatically lubricate the contact part between the bottom of the adjustment block 103 and the threaded column 108, thereby reducing the friction during the subsequent movement. At the same time, the contact part between the top of the adjustment block 103 and the threaded column 108 can also be lubricated once, thereby reducing the friction during the initial operation, and reducing the wear and damage of the adjustment block 103 at the beginning of the adjustment.
