Description

Technical Field

[0001] The utility model relates to the technical field of flying backpacks, and more specifically, to a double-rotor single-person backpack-type flying backpack. Background Art

[0002] A flight backpack is an aircraft that allows the user to wear the product and use a console to operate a vertical engine that mimics the working principle of an airplane engine, and can carry the operator into the sky.

[0003] Currently, mainstream flying backpacks on the market all use a dual-rotor structure as their power system. When running, the rotors will be able to generate both lift and pull on the flying backpack, thereby driving the driver to fly and move. However, in actual use, although the existing dual-rotor flying backpacks have basic flight functions, the motors of each rotor on most flying backpacks are independent. This means that each rotor on the dual-rotor flying backpack must be equipped with a separate motor, which increases the cost of producing and maintaining the flying backpack. In addition, since the two motors are independent of each other, it is easy for the two motors to have different speeds. At this time, the two rotors will generate different lift and pull on the flying backpack, resulting in unstable flight of the flying backpack, which in turn poses a danger to the driver's flight use. Therefore, it needs to be improved. Utility Model Content

[0037] When the driving gear 8 rotates, it will drive the two circular shafts 10 to rotate along the inside of the two short plates 11 through the two driven gears 9. Since the two square rods 12 are square in shape, the two circular shafts 10 will drive the two circular rods 13 to rotate along the inside of the two connecting plates 15 through the two square rods 12. Since the two first gears 17 are meshed with the two second gears 18, the two circular rods 13 will drive the two second gears 18 to rotate through the two long shafts 16 and the two first gears 17. Then the two second gears 18 will drive the two rotors 6 and the two rotating rings 5 ​​to rotate inside the two support rings 4.

[0038] The driving mechanism includes:

[0039] A fixing plate 7, the back of which is fixedly connected to the top of the front of the backpack body 1, and the bottom of which is movably connected to the top of the driving gear 8;

[0042] There are two fixing blocks 21 fixedly mounted on both the left and right sides of the backpack body 1 , and a back plate 22 is fixedly mounted between the two fixing blocks 21 .

[0043] Due to the design of the back plate 22 , the driver can wear the backpack body 1 as a whole comfortably.

[0044] Among them, a first safety belt 23 is fixedly installed at the bottom end of the backboard 22, and a plug plate 24 is fixedly installed at the other end of the first safety belt 23. A latch 25 is movably sleeved inside the plug plate 24, and a second safety belt 26 is fixedly installed at the other end of the latch 25. The other end of the second safety belt 26 is fixedly connected to the back of the backpack body 1.

[0045] Due to the design of the first safety belt 23 and the second safety belt 26, the driver can be well protected.

[0046] The two fixing blocks 21 are fixedly mounted with armrests 27 on opposite sides thereof, and a control lever 28 is fixedly mounted behind the top of the armrests 27 .

[0047] Due to the design of the two operating levers 28 , the operator can control the entire backpack body 1 to move through the two operating levers 28 .

[0048] Among them, a fixing frame 30 is fixedly installed on the top of the backpack body 1, and a power motor 31 is fixedly installed on the top of the fixing frame 30. The other end of the output shaft of the power motor 31 is fixedly sleeved with a rotating shaft 32, and the bottom end of the rotating shaft 32 passes through the top of the fixing frame 30 and extends to the inside of the fixing frame 30.

[0049] When the power motor 31 is running, the rotating shaft 32 will rotate.

[0050] Among them, a screw 33 is fixedly installed at the bottom end of the rotating shaft 32, and the bottom end of the screw 33 is movably connected to the top of the backpack body 1. The outer surface of the screw 33 is threadedly sleeved with a square block 34, and the outer surface of the square block 34 is movably connected to a limit block 35. The top of the limit block 35 is fixedly connected to the top inside the fixing frame 30, and the bottom end of the limit block 35 is fixedly connected to the top of the backpack body 1.

[0051] When the rotating shaft 32 rotates, the screw 33 will rotate driven by the rotating shaft 32. Since the outer surface of the screw 33 is engaged with the internal thread of the square block 34, the screw 33 will drive the square block 34 to move when it rotates. Due to the limiting effect of the limit block 35, the square block 34 will move downward along the inside of the limit block 35 driven by the screw 33.

[0052] The left and right sides of the square block 34 are both fixedly mounted with first hinge blocks 36 , a motion rod 37 is hinged inside the first hinge block 36 , and the other end of the motion rod 37 is hinged to a second hinge block 38 .

[0053] When the square block 34 moves downward, the two first hinge blocks 36 will move downward driven by the square block 34 , and the two first hinge blocks 36 will drive the two second hinge blocks 38 to move via the two motion rods 37 .

[0054] Among them, the other end of the second hinged block 38 is fixedly installed with a first movable plate 39, the bottom end of the first movable plate 39 is movably connected to the top end of the limit plate 29, and the bottom end of the first movable plate 39 is fixedly installed with a movable block 40, and the outer surface of the movable block 40 is movably connected to the inside of the limit plate 29.

[0055] When the two second hinge blocks 38 move, the two second hinge blocks 38 will drive the two movable blocks 40 to move through the two first movable plates 39. Due to the limiting effect inside the limiting plate 29, the two first movable plates 39 will drive the two movable blocks 40 to move away from each other.

[0056] Among them, a second movable plate 41 is fixedly installed on the front of the first movable plate 39, and the inner part of the other end of the second movable plate 41 is movably connected to the outer surface of the round rod 13. The outer surface of the second movable plate 41 is movably connected to a second fixed ring 42, and the inner part of the second fixed ring 42 is fixedly connected to the outer surface of the round rod 13.

[0057] When the two movable blocks 40 move away from each other, the two second movable plates 41 will move away from each other driven by the two movable blocks 40. At the same time, the two second movable plates 41 will squeeze and push the two sets of second fixed rings 42 to drive the two round rods 13 to move away from each other as a whole. In this process, the two round rods 13 will drive the two connecting plates 15 to move away from each other through the two sets of first fixed rings 14. Then the two connecting plates 15 will drive the two movable plates 2 to move away from each other as a whole.

[0058] The working principle and use process of this utility model:

[0059] First, the driver starts the drive motor 19, and the rotating shaft 20 will drive the driving gear 8 to rotate. Since the driving gear 8 is meshed with the two driven gears 9, when the driving gear 8 rotates, it will also drive the two driven gears 9 to rotate. At this time, the two circular shafts 10 will rotate along the inside of the two short plates 11 driven by the two driven gears 9. At this time, the two circular shafts 10 will respectively drive the two square rods 12 to rotate. Since the two square rods 12 are square in shape, the two circular rods 13 will rotate along the inside of the two connecting plates 15 driven by the two square rods 12. Rotation, due to the design of the two connecting plates 15, the two round rods 13 will have a good supporting effect, and then the two round rods 13 will drive the two first gears 17 to rotate through the two long shafts 16. Since the two first gears 17 are respectively engaged with the two second gears 18, when the two first gears 17 rotate, they will respectively drive the two second gears 18 to rotate. Then, the two second gears 18 will simultaneously drive the two rotors 6 and the two rotating rings 5 ​​to rotate inside the two support rings 4, thereby realizing the function of driving the two rotors 6 to rotate simultaneously by a group of motors.

[0060] Then the driver starts the power motor 31, and the rotating shaft 32 will drive the screw 33 to rotate. Since the outer surface of the screw 33 is threadedly connected to the internal thread of the square block 34, when the screw 33 rotates, it will drive the square block 34 to move. Due to the design of the limit block 35, the movement of the square block 34 will be limited, so that the square block 34 can only move up and down. At this time, the square block 34 will move downward along the inside of the limit block 35 under the drive of the screw 33. At this time, the square block 34 will simultaneously drive the two first hinge blocks 36 to move, and then the two first hinge blocks 36 will respectively drive the two motion rods 37 to move, and then the other ends of the two motion rods 37 will respectively push the two second hinge blocks 38, so that the two second hinge blocks 38 drive the two first movable plates 39 to move. At this time, the two movable blocks 40 will move under the drive of the two first movable plates 39. Due to the internal design of the limiting plate 29, the movement of the two movable blocks 40 will be limited so that they can only move left and right. At this time, the two first movable plates 39 will drive the two movable blocks 40 to move away from each other. Then the two movable blocks 40 will drive the two sets of second fixed rings 42 to move through the two second movable plates 41. Then the two sets of second fixed rings 42 will drive the two round rods 13 to move away from each other as a whole. At the same time, the two round rods 13 will squeeze and push the two connecting plates 15 through the two sets of first fixed rings 14, so that the two connecting plates 15 drive the two moving plates 2 to move away from each other as a whole, so that the overall expansion angle of the two moving plates 2 can be telescopically adjusted, thereby improving the overall flight stability of the backpack body 1.
