Description

Technical Field

[0001] This utility model relates to the field of flight backpack technology, and more specifically, to a single-person wearable jet flight backpack. Background Technology

[0002] A flight backpack is a type of aircraft that allows users to operate a vertical engine that mimics the working principle of an airplane engine by wearing the product and using a control console, enabling the operator to take to the sky.

[0003] Current flight backpack technology is mainly based on jet propulsion. Currently, flight backpacks on the market require operators to wear the jet aircraft on their hands, and control the aircraft by turning their hands. However, when worn on the operator's hands, the weight of the aircraft often causes discomfort, leading to fatigue and discomfort after long-term flights. When operators are fatigued for a long time and try to turn the flight backpack, improper operation may occur, causing accidents. This brings inconvenience and danger to operators, so improvements are needed. Utility Model Content

Immediately afterwards, the first hinge block will drive the second hinge block to move via a moving rod. At this time, the second hinge block will drive the first nozzle to rotate around the hinge point of the third and fourth hinge blocks. When the two screws rotate, the moving block will drive the limiting block to move as a whole via the circular shaft and the movable block. Since the rotating block is internally connected to the long plate, the first nozzle will rotate around the movable connection point between the rotating block and the long plate, thereby allowing the backpack body to easily change its flight turning angle.

Due to the design of the moving plate, when the first and second plugs are inserted into the slot plate, they press against the stop block, causing the stop block to move the square plate to the left. When the first and second plugs are inserted into the slot plate, the spring force causes the stop block to move to the right into the interior of the first and second plugs, locking them inside the slot plate. When the square rod moves the moving plate to the left, the moving plate moves the square plate and the three stop blocks to the left. During this leftward movement, the three stop blocks release the lock on the second and first plugs, allowing them to be pulled out from inside the slot plate. This makes the backpack easy to put on and take off. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 6 As shown, this utility model provides a single-person wearable jetpack, comprising:

[0030] Backpack body 1, a long plate 2 is fixedly installed on the right side of backpack body 1, and a short plate 3 is fixedly installed on the top of the long plate 2.

[0031] A steering mechanism is located at the top of the backpack body 1;

[0032] The steering mechanism includes a pneumatic cylinder 4, the bottom of which is fixedly connected to the top of the short plate 3. The other end of the pneumatic cylinder 4 passes through the top of the short plate 3 and extends to below the bottom of the short plate 3. A circular block 5 is fixedly installed on the other end of the pneumatic cylinder 4. A dual-axis motor 6 is fixedly sleeved inside the circular block 5. A screw 7 is fixedly sleeved on the other end of the output shaft of the dual-axis motor 6. A moving block 8 is threaded onto the outer surface of the screw 7. A limit block 9 is movably connected to the right side of the moving block 8. A circular shaft 10 is movably sleeved inside the moving block 8. A moving block 11 is fixedly installed on the right side of the circular shaft 10. The outer surface of the moving block 11 is movably connected to the inside of the limit block 9. The right side of the moving block 11 is fixedly... A first hinge block 12 is installed, with its left side movably connected to the right side of the limiting block 9. A moving rod 13 is hinged inside the first hinge block 12, and a second hinge block 14 is hinged to the other end of the moving rod 13. A first nozzle 15 is fixedly installed on the right side of the second hinge block 14, and a third hinge block 16 is fixedly installed at the top of the first nozzle 15. A fourth hinge block 17 is hinged inside the third hinge block 16, and a square block 18 is fixedly installed on the left side of the fourth hinge block 17. The bottom end of the square block 18 is fixedly connected to the top end of the limiting block 9, and a rotating block 19 is fixedly installed on the left side of the square block 18. The outer surface of the rotating block 19 is movably sleeved with the inside of the long plate 2.

[0033] When the pneumatic cylinder 4 is running, its bottom end will drive the dual-axis motor 6 and two screws 7 downwards via the circular block 5. The two screws 7 will then drive the two movable blocks 11 downwards via the two moving blocks 8 and two circular shafts 10. Immediately afterwards, the two movable blocks 11 will drive the two moving rods 13 via the two first hinge blocks 12. The other ends of the two moving rods 13 will then press and push the two second hinge blocks 14, causing the two second hinge blocks 14 to drive the two first nozzles 15 to rotate around the hinge points of the two third hinge blocks 16 and the two fourth hinge blocks 17. When the dual-axis motor 6 is running, the two screws 7 are threadedly connected to the two moving blocks 8. At this time, the two screws 7 will drive the two moving blocks 8 to move back and forth. Then, the two moving blocks 8 will drive the two movable blocks 11 to move back and forth through the two round shafts 10. Subsequently, the two movable blocks 11 will drive the two square blocks 18 to move as a whole through the two limit blocks 9. Since the two rotating blocks 19 are movably connected to the inside of the long plate 2, the two square blocks 18 will rotate as a whole around the two rotating blocks 19. At this time, the two first nozzles 15 will rotate under the drive of the two square blocks 18 as a whole.

[0034] The backpack body 1 has a fixed frame 20 on both the front and rear sides, and a second nozzle 21 is fixedly connected to the other end of the fixed frame 20.

[0035] Due to the design of the two second nozzles 21, the backpack body 1 will continuously provide upward power.

[0036] The backpack body 1 has two fixing plates 22 fixedly installed on both the front and rear sides. The back panel 23 is fixedly installed on the left side of the two fixing plates 22 facing each other.

[0037] The design of the back panel 23 will make it more comfortable for operators to wear the backpack body 1 as a whole.

[0038] Each of the two fixed plates 22 has a handrail 24 fixedly installed at one of its opposite ends, and a control lever 25 is fixedly installed on the left side of the top of the handrail 24.

[0039] The design of the two handrails 24 provides good support for the operator's arms, and the design of the two control levers 25 allows the operator to control the pneumatic cylinder 4 and the dual-axis motor 6 respectively.

[0040] The back panel 23 has a first safety belt 26 fixedly installed at the bottom end, a slot plate 27 fixedly installed at the other end of the first safety belt 26, a fixing block 28 fixedly installed on the outer surface of the slot plate 27, and a stop block 31 movably sleeved inside the left side of the slot plate 27.

[0041] The design of the first safety belt 26 will provide good protection for the operator.

[0042] The slot plate 27 has a first plug 30 movably sleeved inside the front and rear sides. The inside of the first plug 30 is movably connected to the stop block 31. The outer surface of the first plug 30 is fixedly installed with a second safety belt 29. The other end of the second safety belt 29 is fixedly connected to the outer surface of the back plate 23.

[0043] The design of the two second safety belts 29 will further protect the operator. Due to the design of the two, when the stop block 31 comes into contact with the inside of the two first plugs 30, the stop block 31 will lock the two first plugs 30.

[0044] Among them, the top of the front and rear sides of the backpack body 1 are movably fitted with circular blocks 35, and the outer surface of the circular blocks 35 is fixedly installed with arc-shaped rods 36, and the other end of the arc-shaped rods 36 is fixedly installed with round rods 37.

[0045] Since both circular blocks 35 are movably connected to the outer surface of the backpack body 1, the two arc rods 36 can drive the round rod 37 to rotate around the two circular blocks 35 as the axis. Due to the design of the round rod 37 and the two arc rods 36, it will play a protective role for the operator.

[0046] The bottom end of the round rod 37 is fixedly installed with a third safety belt 38, and the bottom end of the third safety belt 38 is fixedly installed with a second plug 39. The bottom end of the outer surface of the second plug 39 is movably connected to the inside of the top end of the slot plate 27, and the inside of the second plug 39 is movably connected to the stop block 31.

[0047] When the outer surface of the stop block 31 is in movable connection with the interior of the second plug 39, the stop block 31 will lock the movement of the second plug 39. Due to the design of the third safety belt 38, the entire round rod 37 can be connected to the slot plate 27 through the third safety belt 38 and the second plug 39, thereby providing good protection for the operator driving the backpack body 1.

[0048] Among them, a moving plate 32 is movably sleeved on the outer surface of the left end of the stop block 31, the right side of the moving plate 32 is movably connected to the left side of the slot plate 27, a square plate 33 is fixedly installed on the left end of the stop block 31, a spring 34 is fixedly installed on the left side of the square plate 33, and the left end of the spring 34 is fixedly connected to the inside of the fixing block 28.

[0049] When the moving plate 32 moves to the left, it will simultaneously drive the three square plates 33 to move to the left. At this time, the three square plates 33 will drive the three stop blocks 31 to move to the left. Meanwhile, the three springs 34 will be in a compressed state. When the three stop blocks 31 cancel contact with the inside of the second plug 39 and the two first plugs 30 during the leftward movement, the stop blocks 31 will release the locking effect on the second plug 39 and the two first plugs 30, so that the second plug 39 and the two first plugs 30 can be pulled out from the inside of the slot plate 27.

[0050] A square rod 40 is fixedly installed on the left side of the motion plate 32. One end of the square rod 40 passes through the interior of the fixing block 28 and extends to the left side of the fixing block 28. A pull ring 41 is fixedly installed on the left side of the square rod 40. The right side of the pull ring 41 is movably connected to the left side of the fixing block 28.

[0051] Due to the design of the pull ring 41, the operator can drive the square rod 40 to move through the pull ring 41. When the square rod 40 moves, the moving plate 32 will move under the drive of the square rod 40.

[0052] Working principle and usage process of this utility model:

[0053] First, the operator presses the buttons on the two control levers 25 to control the operation and shutdown of the pneumatic cylinder 4 and the dual-axis motor 6. When the pneumatic cylinder 4 is running, its bottom will drive the circular block 5 to move downwards. Then, the circular block 5 will drive the dual-axis motor 6 to move downwards. At this time, the two screws 7 will move downwards under the drive of the dual-axis motor 6. Subsequently, the two screws 7 will drive the two moving blocks 8 to move downwards. The two moving blocks 8 will then drive the two movable blocks 11 along the two limit blocks 9 via the two circular shafts 10. The internal mechanism moves downwards, and simultaneously, the two movable blocks 11 drive the two first hinge blocks 12 to move downwards. At this time, the two first hinge blocks 12 will respectively drive the two moving rods 13 to move. Subsequently, the other ends of the two moving rods 13 will drive the two second hinge blocks 14 to move. The two second hinge blocks 14 will then drive the two third hinge blocks 16 to move through the two first nozzles 15. Since the two third hinge blocks 16 are hinged to the two fourth hinge blocks 17, the two first nozzles 15 will then move with the two third... The hinge block 16 rotates around the hinge point of the two fourth hinge blocks 17, thereby adjusting the jet angle of the two first nozzles 15. When the dual-axis motor 6 is running, the two screws 7 will rotate simultaneously. Since the outer surfaces of the two screws 7 are respectively threaded into the inner threads of the two moving blocks 8, when the two screws 7 rotate, they will drive the two moving blocks 8 to move back and forth. At this time, the two moving blocks 8 will drive the two movable blocks 11 to move through the two round shafts 10. At this time, the two movable blocks 11 will squeeze and push the inside of the two limiting blocks 9 during the movement. Then, the two limiting blocks 9 will drive the two square blocks 18 to move as a whole. During this process, the two round shafts 10 will rotate inside the two moving blocks 8. Since the two rotating blocks 19 are both movably connected to the inside of the long plate 2, the two square blocks 18 will rotate in the same direction around the movable connection point between the two rotating blocks 19 and the long plate 2. At this time, the two first nozzles 15 will rotate under the drive of the two square blocks 18 as a whole, thereby realizing the function of conveniently changing the flight turning angle.

[0054] When the operator needs to put on the backpack body 1, the operator first leans against the left side of the back panel 23, then picks up the slot plate 27, and then inserts the second plug 39 and the two first plugs 30 into the slot plate 27. Due to the design of the stop block 31, when the first plug 30 and the second plug 39 come into contact with the stop block 31, they will press against the outer surface of the stop block 31. At this time, the stop block 31 will drive the square plate 33 to move to the left, and the spring 34 will be in a compressed state. When the other ends of the first plug 30 and the second plug 39 are fully inserted into the slot plate 27, due to the elastic force of the spring 34, the first plug 30 will move to the right to reset under the action of the spring 34. At this time, the outer surface of the first plug 30 will be movably connected with the second plug 39 and the two first plugs 30 respectively. At this time, the first plug 30 will affect the movement of the second plug 39 and the two first plugs 30. The system acts as a barrier, allowing the operator to easily put on the backpack body 1. When the operator finishes flying, they pull the pull ring 41, causing the square rod 40 to move to the left. Subsequently, the moving plate 32 moves to the left via the square rod 40. Then, the moving plate 32 drives the three stops 31 to move to the left via the three square plates 33. During this process, the three springs 34 are compressed. When the three stops 31 release their contact with the second plug 39 and the two first plugs 30 during the leftward movement, they no longer block the movement of the second plug 39 and the two first plugs 30. At this point, the operator can pull the second plug 39 and the two first plugs 30 out of the slot plate 27, allowing the operator to easily remove the backpack body 1, thus achieving the function of easy putting on and taking off the backpack body 1.
