Description

Technical Field

[0001] This invention belongs to the field of flight equipment protection technology, specifically relating to a safety protection device for flying go-karts. Background Technology

[0002] Flying cars can travel on roads like regular cars, while also avoiding traffic jams by flying through the air, allowing them to reach their destination quickly and conveniently. However, flying cars may crash during their flight. If a flying car chooses to make an emergency landing, the difficulty in controlling its altitude and speed means that a crash could cause more serious injuries to people or damage to ground facilities than a traditional vehicle.

[0003] The existing flying go-kart with announcement number CN108891217A includes a body and two parachute devices; the two parachute devices are respectively positioned opposite each other on both sides of the body. When the flying go-kart loses power in the air, the body will plummet rapidly. At this time, the user will activate the parachute devices. Due to the principle of air resistance, the parachutes inflate and deploy relative to the air, slowing down the descent speed. The parachute device of this flying go-kart provides the user with time for emergency response and self-rescue, and also reduces the impact force when the body collides with the ground, thereby improving the safety of the flying go-kart.

[0004] However, some problems exist: 1. Most current flying go-karts are purely battery-powered. Therefore, if a malfunction occurs, they can easily lose power, and other control systems will also fail. When the flying go-kart completely loses power, the parachute cannot be deployed electrically, which can easily lead to a crash. 2. Existing mechanical parachute deployment requires manual operation. Many inexperienced drivers may easily forget or be too afraid to act, resulting in the parachute failing to deploy. Summary of the Invention

[0005] This solution provides a safety protection device for flying go-karts to solve the problem that the operator cannot open the parachute when the power fails.

[0006] This solution provides a safety protection device for a flying go-kart, including a parachute: the parachute is used on the flying go-kart, which is equipped with a power unit, a control system, and a power source, both of which are electrically connected to the power source; a receiving cavity: the receiving cavity is used to house the parachute and is located inside the flying go-kart; a hatch: the hatch is used to open and close the receiving cavity, and is rotatably connected to the receiving cavity by a torque spring; the receiving cavity is equipped with a first electromagnet, the hatch is made of a ferromagnetic material, the first electromagnet cooperates with the hatch, and the first electromagnet is electrically connected to the control system.

[0007] The principle of this scheme is as follows: both the air inlet and outlet of the cylinder are equipped with one-way valves. In the initial state, the hatch will open under the action of the torque spring. At this time, the operator turns on the power and operates the control system to energize the first electromagnet. Then, the operator manually closes the hatch, and the hatch will remain closed under the action of the first electromagnet. When the flying go-kart needs to open the parachute while it is running, the operator operates the control system to de-energize the first electromagnet. The hatch opens automatically under the action of the torque spring, and the parachute flies out of the housing cavity under the action of inertia, thus completing the opening of the parachute.

[0008] When the flying go-kart loses power due to a malfunction, the existing electric parachute deployment method cannot be implemented. In this solution, when the flying go-kart loses power due to a malfunction, the first electromagnet of the hatch is de-energized. At this time, the hatch will automatically open under the action of the torque spring, and the parachute will fly out of the housing cavity under the action of inertia, thus completing the deployment of the parachute.

[0009] The beneficial effect of this solution is that the device can automatically open the parachute hatch when the power supply of the flying go-kart fails.

[0010] Furthermore, it also includes a manual triggering mechanism, which comprises: a push plate: the push plate is slidably connected to the receiving cavity and forms an air intake chamber with the receiving cavity, and the parachute is mounted on the push plate; a cylinder: the cylinder is provided with an air outlet and an air inlet, the air outlet is connected to the air intake chamber, the cylinder is fixedly connected to the flying go-kart; a piston: the piston is slidably connected to the cylinder; and a pull rod: one end of the pull rod is fixedly connected to the piston, and the other end is located in the driver's cab of the flying go-kart.

[0011] When the flying go-kart loses power due to a malfunction, the operator can manually push a lever. This lever moves a piston, which compresses the gas in the cylinder, forcing it out of the outlet and into the intake chamber. The increased pressure in the intake chamber pushes a pusher plate, which then ejects the parachute, making it easier for the parachute to exit the containment chamber and assisting in its deployment. This mechanism improves the parachute deployment success rate and effectively prevents the parachute from getting stuck in the containment chamber.

[0012] Furthermore, it also includes a mechanical triggering mechanism, which includes a triggering cavity and a triggering ball. The triggering cavity is connected to a storage chamber, and the storage chamber is connected to an air intake chamber. The storage chamber contains NaN3 material, and the surface of the triggering ball is provided with a flint. The triggering ball is slidably connected to the triggering cavity, and a friction plate is provided at the connection between the triggering cavity and the storage chamber. The friction plate cooperates with the triggering ball.

[0013] When the power supply fails, the control system malfunctions. Although the hatch can open automatically, a mechanism is still needed to deploy the parachute. While this device allows for manual parachute deployment, operators often forget to do so due to inexperience or nervousness. Therefore, a mechanism that automatically deploys the parachute based on mechanical judgment is needed. In this design, when both the power supply and the power unit fail simultaneously, the flying go-kart falls freely. Due to inertia, the trigger ball moves upward relative to the go-kart, striking the friction plate. The friction between the friction plate and the flint on the trigger ball generates sparks, igniting the NaN3 substance in the storage chamber. The NaN3 reacts with the flame, expanding into gas. This gas enters the air intake chamber, causing the pusher plate to move. Simultaneously, the first electromagnet is de-energized, the hatch opens, and the parachute is successfully deployed by the pusher plate.

[0014] Furthermore, it also includes an anti-accidental touch mechanism, which includes a baffle, a guide rail, a second electromagnet, and a spring. The second electromagnet is fixedly connected to the trigger cavity, the guide rail is fixedly connected to the flying go-kart, one end of the spring is fixedly connected to the guide rail, and the other end is fixedly connected to the baffle. The baffle is slidably connected to the guide rail, and the baffle cooperates with the second electromagnet. The second electromagnet is electrically connected to the power supply.

[0015] When the operator is rapidly diving or moving up and down, the mechanical triggering mechanism is easily triggered accidentally. In this solution, when the power is not lost, the second electromagnet attracts the baffle, so that the baffle is in front of the friction plate and the trigger ball to prevent accidental triggering. When the power fails, the second electromagnet loses power, and the baffle is removed along the guide rail under the action of the spring. At this time, when the flying go-kart loses power and falls, the trigger ball can hit the friction plate.

[0016] Furthermore, the trigger ball is made of copper-aluminum alloy or iron. Copper-aluminum alloy has excellent corrosion resistance, while iron balls are not easily damaged.

[0017] Furthermore, it also includes a bottom airbag, which is fixedly connected to the bottom of the flying go-kart and communicates with the storage chamber. When the electronic or mechanical triggering mechanism is triggered, a large amount of gas is generated in the air intake chamber. Some of this gas goes to the bottom airbag, causing it to fill with gas as well, protecting the flying go-kart from damage upon landing and providing it with a cushioning effect.

[0018] Furthermore, the parachute includes a canopy, parachute lines, and an opener. The canopy and parachute lines are fixedly connected, and the opener is fixedly connected to a receiving cavity. The opener is equipped with a pull bolt, which is fixedly connected to a push plate. The opener assists in the deployment of the parachute. The opener uses an existing type, requiring only the pull bolt to operate. When not triggered, the push plate is in its initial position, and the pull bolt is inserted into the opener. When triggered, the push plate is lifted by the gas, and the pull bolt also moves upward, pulling the bolt out of the opener. This triggers the opener, assisting in the deployment of the parachute. This mechanism improves the success rate of parachute deployment.

[0019] Furthermore, the canopy is composed of multiple canopy panels pieced together, forming a hemispherical shape when opened; and a vent is located in the center of the canopy. The vent regulates the pressure inside and outside the canopy, preventing pressure differences, reducing violent swaying, ensuring stable flight, and guaranteeing a smooth landing.

[0027] The basics are as follows: Figure 1 As shown:

[0028] This solution provides a flying go-kart 1, which is an existing new energy flying car. Its main power source is an electric motor. The flying go-kart 1 has four fan blades 5 arranged in an H-shape, each driven by a brushless motor 3. The brushless motor 3 is electrically connected to the power source. A protective ring 6 surrounds the fan blades 5 to prevent foreign objects from entering. The bottom of the flying go-kart 1 also has wheels 7 for ground travel. The fan blades 5 are fixedly connected to the flying go-kart 1 via connecting rods 4. The flying go-kart 1 has a driver's cab, which can accommodate a seat 8 and control sticks. The flying go-kart 1 also has an observation window 2 for the operator to observe the external environment.

[0029] The basics are as follows: Figure 2 As shown:

[0030] The safety protection device is located inside the flying go-kart 1. This solution provides a safety protection device for the flying go-kart, including an anti-accidental triggering mechanism 9, a manual triggering mechanism 12, an electronic triggering mechanism, a mechanical triggering mechanism 15, a parachute 10, a hatch 11, and a receiving cavity 13.

[0031] Parachute 10 is used on flying go-kart 1, and housing cavity 13 is used to house parachute 10 and is located inside flying go-kart 1; hatch 11 is used to open and close housing cavity 13, and hatch 11 and housing cavity 13 are rotatably connected by torque spring 32; hatch 11 is provided with a first electromagnet, the first electromagnet cooperates with housing cavity 13, and the first electromagnet is electrically connected to a power source.

[0032] As attached Figure 3 , Figure 5 As shown:

[0033] The manual triggering mechanism 12 includes a push plate 18, a cylinder 24, a piston 22, and a pull rod 20. The push plate 18 is slidably connected to the receiving cavity 13, and the push plate 18 and the receiving cavity 13 form an air intake cavity 16. The cylinder 24 is provided with an air outlet 21 and an air inlet 23. The air outlet 21 is connected to the air intake cavity 16. The cylinder 24 is fixedly connected to the flying go-kart 1. The piston 22 is slidably connected to the cylinder 24. One end of the pull rod 20 is fixedly connected to the piston 22, and the other end is located in the driver's cab of the flying go-kart 1. Both the air inlet 23 and the air outlet 21 of the cylinder 24 are provided with one-way valves 28.

[0034] The parachute 10 includes a canopy, parachute lines, and an opener 19. The canopy and parachute lines are fixedly connected, and the parachute lines are fixed to a push plate. The opener 19 is fixedly connected to a receiving cavity 13 and has a pull bolt 17, which is fixedly connected to a push plate 18. The canopy is composed of multiple canopy panels, and when opened, it forms a hemispherical shape. A vent is located in the center of the canopy. The vent regulates the pressure inside and outside the canopy, preventing pressure differences, reducing violent swaying, ensuring stable flight, and guaranteeing a smooth landing. The parachute opener 19 assists in the deployment of the parachute. The parachute opener 19 is an existing type that can be used simply by pulling the latch 17. When not triggered, the push plate 18 is in the initial position and the latch 17 is inserted into the parachute opener 19. When triggered, the push plate 18 is moved upward by the gas, and the latch 17 also moves upward. The latch 17 is pulled out from the parachute opener 19, triggering the parachute opener 19 and assisting in the deployment of the parachute. This mechanism improves the success rate of parachute deployment.

[0035] As attached Figure 4 , Figure 5 As shown:

[0036] The mechanical triggering mechanism includes a trigger chamber 25 and a trigger ball 26. The trigger chamber 25 is connected to a storage chamber 14, which is connected to an air intake chamber 16 via a connecting pipe 27. The connecting pipe 27 is equipped with a one-way valve 28 leading from the storage chamber 14 to the air intake chamber 16. The storage chamber 14 contains NaN3. The surface of the trigger ball 26 is covered with a flint. The trigger ball 26 is slidably connected to the trigger chamber 25. A friction plate 33 is located at the connection point between the trigger chamber 25 and the storage chamber 14. When the flying go-kart 1 is not falling, the trigger ball 26 is positioned below the friction plate 33 due to gravity. When the flying go-kart 1 falls, the trigger ball 26 impacts the friction plate 33. The trigger ball 26 is made of copper-aluminum alloy or an iron ball. Copper-aluminum alloy has excellent corrosion resistance, while iron balls are less prone to damage.

[0037] The anti-accidental touch mechanism 9 includes a baffle 31, a guide rail 34, a second electromagnet 30, and a spring 32. The second electromagnet 30 is fixedly connected to the trigger chamber 25, the guide rail 34 is fixedly connected to the flying go-kart 1, one end of the spring 32 is fixedly connected to the guide rail 34, and the other end is fixedly connected to the baffle 31. The baffle 31 is slidably connected to the guide rail 34. The baffle 31 cooperates with the second electromagnet 30, and the second electromagnet 30 is electrically connected to the power supply.

[0038] like Figure 1-5 As shown:

[0039] The principle of this scheme is as follows: In the initial state, the hatch 11 will open under the action of the torque spring. At this time, the operator turns on the power and operates the control system to energize the first electromagnet. Then, the operator manually closes the hatch 11. The hatch 11 will remain closed under the action of the first electromagnet. When the flying go-kart needs to open the parachute 10 while it is running, the operator operates the control system to de-energize the first electromagnet. The hatch 11 will open automatically under the action of the torque spring. The parachute 10 will fly out from the receiving cavity 13 under the action of inertia, thus completing the opening of the parachute 10.

[0040] Most modern flying go-karts are purely battery-powered, so they are prone to losing power and other control systems will also fail if a malfunction occurs. When flying go-kart 1 loses power due to a malfunction, the existing electrically operated parachute 10 cannot be deployed. In this solution, when flying go-kart 1 loses power due to a malfunction, the first electromagnet of the hatch 11 is de-energized. At this time, the hatch 11 will automatically open under the action of the torque spring 32. Then, the operator manually pushes the lever 20, causing it to move. The lever 20 drives the piston 22, which compresses the gas in the cylinder 24, causing the gas to exit from the outlet 21 and enter the intake chamber 16. The increased pressure in the intake chamber 16 pushes the push plate 18, which then pushes out the parachute 10, completing the deployment of the parachute 10.

[0041] If a power supply failure causes the control system to malfunction, and the operator lacks experience or is nervous, they may easily forget to manually open the parachute 10. In this case, a mechanism that can automatically open the parachute 10 through mechanical judgment is needed. In this solution, when both the power supply and the power unit fail simultaneously, the flying go-kart 1 falls freely. Due to inertia, the trigger ball 26 will move upward relative to the flying go-kart 1. At this time, the trigger ball 26 will hit the friction plate 33. The friction between the friction plate 33 and the flint on the surface of the trigger ball 26 will generate sparks, which will ignite the NaN3 substance in the storage chamber 14. The NaN3 substance in the storage chamber 14 will react with the fire and expand into gas. The gas will enter the air intake chamber 16, causing the push plate 18 to move. At the same time, the first electromagnet will be de-energized, the hatch 11 will open, and the parachute 10 can be successfully pushed out by the push plate 18, thus completing the opening of the parachute 10.

[0042] If the power supply is intact, the second electromagnet 30 attracts the baffle 31, so that the baffle 31 blocks the friction plate 33 and the trigger ball 26 to prevent accidental triggering. When the power supply fails, the second electromagnet 30 loses power, and the baffle 31 is pulled out along the guide rail 34 under the action of the spring 32. At this time, when the flying go-kart 1 loses power and falls, the trigger ball 26 can hit the friction plate 33.

[0043] The beneficial effects of this solution are as follows: 1. This device solves the problem that the operator can manually open the parachute 10 when the power supply to the flying go-kart 1 fails. 2. This solution solves the problem that when the power supply fails, and the operator may easily forget to manually open the parachute 10 due to inexperience or nervousness, there is a stable mechanical device to release the parachute 10. 3. This solution solves the problem of some potential accidental triggering of the mechanical trigger mechanism 15.

[0044] Example 2

[0045] The aircraft frame in this design can be adopted. Figure 6 The fan blade 5 is a double-bladed fan 38, with four blades arranged in a four-wing structure. Of course, an eight-wing structure or more can also be used, which can be adjusted according to the actual situation in this field. This structure is more stable, and the two upper and lower double-bladed fan blades 38 at the rear are connected by a through rod 37, as are the two upper and lower double-bladed fan blades 38 at the front.

[0046] Lightweight design: Drone frames are usually made of lightweight materials. This solution uses a carbon fiber frame 39 to reduce the overall weight, thereby improving flight efficiency and endurance.

[0047] High strength: Despite being lightweight, the materials used in drone frames typically have high strength and rigidity, which helps maintain structural stability during flight.

[0048] Compactness: The drone frame design of this solution takes compactness into account, making the drone easier to carry and deploy.

[0049] Aerodynamic optimization: The design of the UAV frame in this solution takes aerodynamics into account, with an overall streamlined shape to reduce drag and improve flight efficiency.
