Description

Technical Field

[0001] The invention belongs to the technical field of aircraft and relates to a lightweight backpack-type manned flying backpack. Background Art

[0002] In recent years, micro-aero engine technology has developed rapidly. Many countries have listed the next generation of individual flight backpacks as key research and development projects, hoping to use this equipment to enhance the combat capabilities of special warfare individuals. At the same time, they are also actively exploring its application potential in military operations and rescue missions. At present, most flight backpack technologies on the market use jet power systems. For example, the JB11 jet flight backpack launched by Jetpack Aviation, the "anti-gravity suit" jet flight suit developed by the founder Richard Browning of Gravity Industries in the UK, and the standing flight pedal invented by Frankie Zapata of France in 2019, all belong to this category.

[0003] However, these existing flying backpacks have two major market pain points. First, they are heavy, which not only shortens the flight time and reduces the flight speed, but also places too high a physical requirement on the pilot. Second, they are complex in structure, which requires users to undergo a period of professional training and master the corresponding operating skills in order to use these flying backpacks safely and effectively. In view of this, there is an urgent need to develop a lightweight manned flying backpack.

[0004] China Patents has published an invention patent with application number CN202410420041.X, which proposes a flying backpack. Although it has a dual control system that combines manual control and leg control, it will directly lead to the flying backpack being too heavy, the pilot being overburdened, inconvenient to operate, and the flight time being greatly reduced. In addition, the structure is complex, which leads to difficulty in production and processing, increased weight, high cost, and a long training cycle. In view of this, it is particularly necessary to develop a lightweight backpack manned flying backpack. This flying backpack focuses on optimizing and improving the lightweight design and operating system. At the same time, only the hand control system greatly reduces the pilot's training time, and can be operated more quickly to improve the overall performance and user experience.

[0005] At present, the Martin flying backpack, Gravity Industries jet flying backpack, JetPack Aviation's JB-10 and Zapata Flyboard Air flying backpacks on the market generally have problems such as complex signal processing and command transmission processes, slow response, and inconvenient operation in terms of control methods. The operation interface either has many buttons or lacks a humanized integrated layout. In addition, flying backpacks are generally heavy, which not only affects flight performance and increases energy consumption, but also places excessive physical demands on pilots, limits flight time and application scenarios, and greatly hinders its promotion and application in emergency rescue, urban air traffic and other fields. In the field of international personal aircraft, although there has been some progress, the operability of single-person aircraft is still the key to restricting development. For example, the New Zealand Martin flying backpack has a long battery life and considerable load, but it is difficult to operate due to the traditional power and mechanical control structure; the GoFast flying backpack has a large investment, limited flight speed and altitude, and complicated control; as a pioneer, the Bell Rocket Belt can fly for a short time with hydrogen peroxide propulsion, but the control is complex and the safety is questionable. These devices generally have complicated control systems and non-intuitive operating interfaces, requiring professional training to operate, which hinders their popularization among the general public.

[0006] Faced with this dilemma, the international community has actively launched attempts to improve the problem of high difficulty in operation. For example, the American JetPack Aviation company took the lead in transforming its JB-11 flying backpack by optimizing the motor torque and speed regulation, combining sensors to collect data, and using processors for dynamic regulation. As for the jet backpack of the British Gravity Industries, the European team uses intelligent algorithms to improve its control accuracy. Although all parties have made many efforts to improve the operability of single-person aircraft and have achieved certain phased results, as of now, a set of lightweight operating systems that are both comprehensive and reliable and a set of reasonable flight backpack material selection solutions have not yet been built. The existing improvement schemes have inherent limitations and cannot fundamentally solve the problems of difficulty in operation and heavy weight. In view of this, there is an urgent need to develop a lightweight backpack manned flying backpack.

[0007] Therefore, it is necessary to propose a lightweight backpack manned flying backpack, which can simplify the parts structure of the flying backpack, significantly reduce the overall weight, improve endurance and maneuverability, be simple to operate, and achieve long-term flight while ensuring safety and performance, so as to solve the problems existing in the existing technology. Summary of the invention

[0008] In view of the shortcomings of the prior art, the present invention aims to provide a lightweight backpack manned flying backpack, including a main body, a power part, and a handle control part. The flying backpack can significantly reduce the overall weight, improve the endurance and maneuverability, and is easy to operate, and can achieve long-term flight, while ensuring safety and performance through structural optimization and combined application of advanced materials.

[0009] The present invention is achieved through the following technical solutions.

The electrical signal is received by the signal receiver and transmitted to the worm motor, thereby changing the tilt angle of the four 60 kg thrust-class engines; the right handle control part includes a right handle joystick, left and right throttle potentiometers, and a throttle potentiometer. The left and right throttle potentiometers are fixed in the left and right throttle potentiometer mounting grooves by screws, and the throttle potentiometer is installed in the through hole at the lower end of the right handle joystick. The pilot controls the right handle joystick to deflect left and right, front and back, and drives the left and right throttle potentiometers or the throttle potentiometer to move, so as to adjust the throttle size of the four 60 kg thrust-class engines.

[0015] Furthermore, the mounting arm bracket is fixed to the main frame through a tubular steel hoop at the upper end of the universal joint. The cross axis of the universal joint adapts to complex motion conditions and allows the mounting arm bracket connected to the universal joint to swing and rotate within a certain range relative to the main frame.

[0016] Further, the tilt casing also includes a bearing cover, an upper baffle plate of a worm motor, a deep groove ball bearing 1, a deep groove ball bearing 2, an elastic retaining ring, and a lower baffle plate of a worm motor.

[0018] The deep groove ball bearing is installed in the arc-shaped deep groove of the lower shell of the tilting casing. There are two deep groove ball bearings, which are respectively fixed together with two identical transmission shafts. The elastic retaining ring is installed in the deep groove at the mouth of the arc-shaped deep groove, and the number of the elastic retaining rings is also two, which limits the axial movement of the deep groove ball bearing. The upper shell of the tilting casing also has two arc-shaped deep grooves that match the lower shell of the tilting casing. When the upper shell of the tilting casing and the lower shell of the tilting casing are assembled together, the deep groove ball bearing is fixed in an arc-shaped deep groove.

[0019] Furthermore, the left handle control part also includes a left display screen, an internal gear meshing connecting rod, a pin shaft, an external gear, a connecting rod, and a shaft damper; the left handle joystick includes a hexagonal head bolt 1, a gasket, a hexagonal nut 1, a hexagonal head bolt 2, and a hexagonal head nut 2; the left display screen is connected and fixed to the upper end of the left handle joystick through the hole above the left handle joystick, and the main frame of the left display screen is made of carbon fiber reinforced nylon material (PA-CF), and the display screen is processed and produced using additive manufacturing technology, which not only takes into account the advantages of lightweight, but also takes into account the advantages of high strength. The gasket, the connecting rod and the left handle joystick are connected together in sequence through a hexagonal head bolt 1 and a hexagonal nut 1 to ensure that the internal gear meshing connecting rod, the connecting rod, and the left handle joystick can rotate freely in a plane to form a connecting rod mechanism, and the left handle joystick is controlled to make corresponding mechanical movements to change the angle of the adjustment tilt torsion spring potentiometer knob. At this time, the electrical signal is received and transmitted by the signal receiver to the worm motor, thereby changing the tilting angle of four 60 kg thrust-class engines, the pin shaft connects the two through the connecting rod threaded hole on the internal gear meshing connecting rod and the smaller through hole of the connecting rod, ensuring the rotation of the internal gear meshing connecting rod and the connecting rod bracket, the internal gear hole on the internal gear meshing connecting rod is meshed and connected with the external gear, the tilt torsion spring potentiometer is connected to the tilt torsion spring potentiometer mounting groove on the mounting arm bracket, the resistance value in the circuit is changed by rotating the tilt torsion spring potentiometer, voltage regulation and signal control are performed, and the tilting angle of the four 60 kg thrust-class engines is adjusted, the shaft damper is embedded in the through hole at the lower end of the left handle joystick, the shaft damper itself is axially connected and fixed by two hexagonal bolts and two hexagonal nuts, the shaft damper can limit the rotation speed of the shaft through its own damping effect, make the movement of the shaft more stable, prevent misjudgment caused by inadvertent accidental operation of the operator, and realize free rotation.

[0058] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0059] A lightweight backpack manned flying backpack, comprising a main body part 1, a power part 2, and a handle control part 3;

[0060] The main body 1 includes an installation arm bracket 11, a universal joint 12, a connecting bracket 13, a main frame 14, a fuel tank 15, a cable tie 16, a cushion 17, and a pipe plug 18. The installation arm bracket 11 is fixed to the main frame 14 through a tubular steel hoop 123. The cross shaft 121 of the universal joint 12 can adapt to complex motion conditions, and can make the installation arm bracket 11 connected to the universal joint 12 swing and rotate within a certain range relative to the main frame 14. These swings and rotations obviously have the effect of redirecting four 60 kg thrust-class engines 22, thereby changing the direction of thrust in a slightly tilted manner. The pilot can adjust the angle according to his own wishes to make the flight backpack reach the desired motion state. The installation arm bracket 11 is a hollow pipe frame structure made of carbon fiber material, which can significantly reduce the weight of the structure. The tensile strength of carbon fiber is more than five times that of steel, which is suitable for bearing high dynamic loads. There are three weight-reducing holes 116 on the left and right sides of the installation arm bracket 11, which saves materials and improves performance by lightweighting. The main frame 14 is connected to the connecting bracket by bolts and nuts. The connecting bracket 13 is fixed together, the main frame 14 is a hollow pipe frame structure, and the carbon fiber material can significantly reduce the weight of the structure. The connecting bracket 13 is made of 7075 aluminum alloy, which ensures strength and rigidity while reducing weight. The cushion 17 is fixed to the connecting bracket 13 by bolts and nuts. A long-life lithium battery is installed inside the cushion 17 to power the flight backpack control system. The fuel tank 15 is firmly tied to the main frame 14 by two cable ties 16, so that the fuel tank 15 is fixed to the main frame 14. The fuel tank 15 provides fuel for four 60 kg thrust-class engines 22. The fuel tank 15 is made of special engineering plastic PEEK. Using PEEK to replace traditional metal fuel tanks can reduce costs by 30% and significantly reduce weight. The cable tie 16 is made of aramid fiber material, which has high strength, light weight, wear resistance and heat resistance. The pipe plug 18 plugs the pipe diameter through hole 117 of the mounting arm bracket 11. The mounting arm bracket 11 and the main frame 14 reduce the structure that needs to be processed by bending process as much as possible, which greatly reduces the processing difficulty;

[0061] The power part 2 includes a tilting case 21, a 60 kg thrust-class engine 22, a tilting case mounting bolt 23, a tilting case mounting nut 24, and an engine fixing clamp 25. The tilting case 21 is fixed on three tilting case mounting holes 111 by three tilting case mounting bolts 23 and three tilting case mounting nuts 24. The tilting case mounting holes 111 are arranged on the mounting arm bracket 11. The tilting case 21 is installed one on each of the left and right sides of the flight backpack, corresponding to the human arm. The threaded slot hole of the engine fixing clamp 25 is fixed to the end of the transmission shaft 213 on the tilting case 21 by threaded connection. Two engine fixing clamps 25 are installed on the tilting cases 21 on both sides; the 60 kg thrust-class engine 22 is fixed by the engine fixing clamp 25. There are four 60 kg thrust-class engines 22. The transmission shaft 213 and the engine fixing clamp 25 are both made of carbon fiber material, which can significantly reduce the structural weight and are suitable for bearing high dynamic loads.

[0062] The tilt casing 21 includes a tilt casing upper shell 211, a tilt casing lower shell 212, a transmission shaft 213, a worm motor 2112, a bearing cover 2113, a worm motor upper baffle 2115, a deep groove ball bearing 1 2123, a deep groove ball bearing 2116, a worm wheel 2122, an elastic retaining ring 2124, a signal receiver 2125, a power supply device 2126, and a worm motor lower baffle 2127. The tilt casing upper shell 211 includes a worm motor upper groove shell 2111 and a bearing mounting groove 2114. The tilt casing lower shell 212 includes a worm motor lower groove shell 2121. The tilt casing upper shell 211 and the tilt casing lower shell 212 are made of carbon fiber material, which is much lighter than traditional metal materials and has a strong structure. The degree of rotation is greatly improved, the worm reducer housing 2112-1 of the worm motor 2112 is installed in the worm motor upper groove shell 2111 of the tilt casing upper shell 211, the worm motor upper baffle 2115 is fixed to the worm motor upper groove shell 2111 of the tilt casing upper shell 211 by screws, and the worm motor lower baffle 2127 is fixed to the worm motor lower groove shell 2121 of the tilt casing lower shell 212 by screws. The worm motor upper baffle 2115 and the worm motor lower baffle 2127 can prevent the worm motor 2112 from sliding out, and play a role of limiting and fixing; the flanges of the tilt casing upper shell 211 and the tilt casing lower shell 212 have a plurality of through holes, and the two are fixed with bolts and nuts through a plurality of through holes of the flanges.

[0063] The worm motor 2112 includes a worm reducer housing 2112-1 and a worm 2112-2. The worm 2112-2 is meshed with two worm wheels 2122, and the transmission is smooth and self-locking. The tooth surface contact strength is high. The advantage of this structure is that the tilt angle of the engine will not change due to other external factors and has self-locking properties. The end of the worm 2112-2 is inserted into the bearing mounting groove 2114 of the upper housing 211 of the tilting casing, which can make the longer worm 2112-2 transmission more stable. Stable, the worm 2112-2 and the worm wheel 2122 are made of titanium alloy, which can achieve lightweight while ensuring the strength and rigidity of the worm and worm wheel; the deep groove ball bearing 2116 is inserted into the bearing mounting groove 2114, and its outer ring and the groove shell are transition fit or interference fit, and the inner ring of the deep groove ball bearing 2116 and the end of the worm 2112-2 are transition fit or interference fit, and the bearing cover 2113 is fixed at the notch of the bearing mounting groove 2114 by screws to fix the deep groove ball bearing 2116 axially.

[0064] The deep groove ball bearing 2123 is installed in the arc-shaped deep groove of the lower shell 212 of the tilting casing. There are two deep groove ball bearings 2123, which are respectively fixed together with two identical transmission shafts 213. The elastic retaining ring 2124 is installed in the deep groove at the mouth of the arc-shaped deep groove, and the number of the elastic retaining rings 2124 is also two, which limits the axial movement of the deep groove ball bearing 2123; the upper shell 211 of the tilting casing also has two arc-shaped deep grooves matching the lower shell 212 of the tilting casing. When the upper shell 211 of the tilting casing and the lower shell 212 of the tilting casing are assembled together, the deep groove ball bearing 2123 is equivalent to being fixed in a circular arc-shaped deep groove.

[0065] A signal receiver 2125 and a power supply device 2126 are installed in the lower shell 212 of the tilting casing. The signal receiver 2125 is used to receive electrical signals and transmit them to the worm motor 2112. The power supply device 2126 is connected to the signal receiver 2125 and the worm motor 2112 through wires to supply power to the signal receiver 2125 and the worm motor 2112.

[0066] The handle control part 3 includes a left handle control part 31 and a right handle control part 32; the left handle control part 31 is installed in the left handle joystick mounting slot 115 of the mounting arm bracket 11, and the left handle control part 31 is connected to the left handle joystick threaded hole 114 of the mounting arm bracket 11 through a hexagonal head bolt 2 3114 and a hexagonal head nut 2 3115, and the tilt torsion spring potentiometer 315 is installed and fixed at the tilt torsion spring potentiometer mounting slot 113 of the mounting arm bracket 11.

The gasket 3112, the connecting rod 317 and the left handle joystick 311 are connected together in sequence through a hexagonal head bolt 3111 and a hexagonal nut 3113 to ensure that the internal gear meshing connecting rod 313, the connecting rod 317, and the left handle joystick 311 can rotate freely in the plane to form a connecting rod mechanism, and the knob angle of the tilt torsion spring potentiometer is changed by making corresponding mechanical movements. At this time, the electrical signal is received by the signal receiver and transmitted to the worm motor, thereby changing the tilt angle of the four 60 kg thrust-class engines. The pin shaft 314 connects the two through the connecting rod threaded hole 3132 on the internal gear meshing connecting rod 313 and the smaller through hole of the connecting rod 317, ensuring the rotation of the internal gear meshing connecting rod 313 and the connecting rod 317 bracket.

[0069] How it works

[0070] The specific process of its working principle is as follows: the four 60 kg thrust-class engines are all micro-turbojet aircraft engines of the same model. The fuel tank provides fuel oil sources for the four 60 kg thrust-class engines. The four 60 kg thrust-class engines provide flight power for the flight backpack. When one or several engines fail, the remaining normally working engines can still provide sufficient thrust to keep the flight backpack in flight, avoiding sudden falls due to single engine failures, greatly reducing the risk of flight accidents, and playing a role in dispersing loads and optimizing layouts. The four engines can be more evenly distributed in various parts of the flight backpack, making the weight distribution of the entire system more reasonable, which is beneficial to the structural design and balance control of the flight backpack, and the tilting casing adopts a worm gear structure with smooth transmission, self-locking, and high tooth surface contact strength. The advantage of this structure is that the tilt angle of the engine will not change due to other external factors, and it has self-locking properties, which greatly improves safety performance and control accuracy. The present invention simplifies the structure of the vector thrust device and the handle control system of the backpack manned flying backpack while ensuring safety and performance through structural simplification and combined application of advanced materials. At the same time, the mounting arm bracket structure and the main frame structure are designed to be lightweight. Compared with the same type of backpack manned flying backpacks, the weight is greatly reduced, the endurance and maneuverability are improved, the operation is simple, and long-term flight can be achieved.

[0071] The following are the working modes and control principles of this backpack manned flying backpack:

[0072] The handle control part includes a left handle control part and a right handle control part. The left handle control part is installed in the left handle joystick mounting slot of the mounting arm bracket. The tilt torsion spring potentiometer is installed and fixed at the tilt torsion spring potentiometer mounting slot of the mounting arm bracket. The pilot controls the left handle joystick by pushing forward or backward, thereby driving the connecting rod mechanism to make corresponding mechanical movements to change the knob angle of the tilt torsion spring potentiometer. At this time, the electrical signal is received by the signal receiver and transmitted to the worm motor, thereby changing the tilt angle of the four 60 kg thrust-class engines; the right handle control part is installed on the left and right throttle potentiometer mounting slots of the mounting arm bracket. The throttle potentiometer is installed in the through hole at the lower end of the right handle joystick. The left and right throttle potentiometers are fixed in the left and right throttle potentiometer mounting slots by screws. The pilot can adjust the throttle size of the four 60 kg thrust-class engines by controlling the right handle joystick to deflect left and right, front and back. The left and right throttle potentiometers and the throttle potentiometers have anti-shake systems and damping to prevent the potentiometers from misjudging due to inadvertent and accidental manipulation by the operator.

[0073] When the tilt angle of the four 60 kg thrust-class engines is 0°, that is, the four 60 kg thrust-class engines are perpendicular to the horizontal line, the pilot drives the flight backpack at this time, controls the right handle joystick with his right hand and pushes it forward, driving the throttle potentiometer to work, and the throttles of the four 60 kg thrust-class engines are increased at the same time. When the jet thrust is greater than the gravity of the entire system, the pilot will drive the flight backpack off the ground.

[0074] When the tilt angle of the four 60 kg thrust-class engines is not 0° and remains tilted forward, the pilot controls the right handle joystick with his right hand to drive the throttle potentiometer to adjust the throttle to the appropriate size. The gravity of the entire system will be balanced by the jet thrust, that is, the two forces are in opposite directions and equal in magnitude; but there is still a horizontal and forward-directed jet thrust. After overcoming the air resistance, this thrust will drive the flight backpack to accelerate forward.

[0075] When the tilt angle of the four 60kg thrust-class engines is not 0° and they remain tilted backward, the pilot controls the right joystick with his right hand to drive the throttle potentiometer to adjust the throttle to the appropriate size. The gravity of the entire system will be balanced by the jet thrust, that is, the two forces are opposite in direction and equal in magnitude; but there is still a horizontal and backward jet thrust, which will drive the flight backpack to accelerate backward after overcoming the air resistance. If the flight backpack is driving forward in the initial state, after this operation, the flight backpack will first decelerate until the horizontal speed is 0, and then accelerate backward.

[0076] When the tilt angle of the four 60 kg thrust-class engines is not 0° and remains in a forward tilted state, the pilot's right hand controls the right handle joystick to deflect to the left to drive the left and right throttle potentiometers to work, the throttles of the two 60 kg thrust-class engines on the right increase, and the throttles of the two 60 kg thrust-class engines on the left remain unchanged. At this time, the jet thrust direction changes, causing the flight backpack system to deviate to the left, even if the flight backpack turns left; similarly, the pilot's right hand controls the right handle joystick to deflect to the right to drive the left and right throttle potentiometers to work, the throttles of the two 60 kg thrust-class engines on the left increase, and the throttles of the two 60 kg thrust-class engines on the right remain unchanged. At this time, the jet thrust direction changes, causing the flight backpack system to deviate to the right, even if the flight backpack turns right.

[0077] The pilot can also control the mounting arm bracket connected to the universal joint to swing and rotate within a certain range relative to the main frame. These swings and rotations obviously have the effect of redirecting the four 60 kg thrust-class engines, thereby changing the direction of the thrust in a slightly tilted manner. The pilot can adjust the angle according to his own wishes to make the flying backpack achieve the desired movement state.

[0078] The left and right display screens show the flight parameters of the flight backpack system itself, such as flight altitude, throttle, fuel level, etc. The pilot can make the next operation based on these parameters. The left display screen is equipped with a signal receiver and controller for the two engines on the left. When the signal receiver receives an electrical signal, it is transmitted to the controller, thereby controlling the throttle of the two engines on the left. The right display screen is equipped with a signal receiver and controller for the two engines on the right. When the signal receiver receives an electrical signal, it is transmitted to the controller, thereby controlling the throttle of the two engines on the right.

[0079] The worm motors of the tilting casings on both sides of the flight backpack are of the same model, and after receiving the same signal, they make consistent judgments and have the same operating status, so the tilt angles of the four 60 kg thrust-class engines are consistent.

For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
