Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aviation amusement and teaching training equipment, in particular to an integrated equipment with ultra-low altitude vertical take-off and landing function, which can meet the needs of amusement experience and aviation operation teaching training at the same time. It is suitable for various scenes such as amusement parks, popular science venues, aviation training institutions, etc., and can safely operate in a relatively dense environment without relying on large open spaces. BACKGROUND

[0002] Currently, there is a clear functional split and use limitation between aviation theme amusement projects and professional aviation teaching training equipment, which is difficult to meet the market demand for "safe, multifunctional and portable" aviation related equipment. The specific problems are as follows: In the field of aviation teaching and training, aircraft driving teaching is a high-risk activity, and the risk runs through the whole training process, mainly concentrated in three core scenes: 1. Student misoperation: novice students are not familiar with control components such as control sticks and throttles, which are prone to "reverse operation" (such as incorrect rudder pressure due to crosswind), "excessive operation" (such as pulling the stick too hard to make the plane drift during landing), or "delayed reaction" (such as not pushing the stick in time to increase speed when the speed is too low), etc. Such operation errors can easily lead to loss of control of flight attitude and increase the risk of training.

[0003] 2. Instructors do not intervene in time: when the student loses control, the instructor may not intervene in time (such as delaying intervention when the student enters a spiral state, resulting in too low altitude), which may cause accidents such as crashes and collisions. The existing equipment lacks an effective "emergency intervention prompt" mechanism, making it difficult for instructors to accurately grasp the intervention timing.

[0004] 3. Multi-machine team coordination failure: In dual-seat trainer training, the instructor and student operation instruction transmission is not clear (such as "I operate" and "you take over" orders being confused), which is prone to double control conflicts, i.e. both parties operating control components at the same time, resulting in chaotic equipment response and further exacerbating safety hazards.

[0005] In the field of aviation amusement experience, existing projects are mostly carried out in high altitude areas, which are high-risk and have significant defects: Single function: Lack of integrated design of "amusement + teaching", only visual, auditory simulation or simple flight experience can be provided, which cannot meet the needs of both amusement experience and practical training, limiting the use of scenes and making it difficult to meet the dual needs of users for "entertainment + practicality".

[0006] Take-off and landing and safety issues: most devices have no vertical take-off and landing capability or require a large take-off and landing space (such as a runway of tens of meters), and the safety cannot be guaranteed, and they are not suitable for use in crowded amusement scenes; some devices have low-altitude flight capability, but lack effective height limiting and collision prevention structures, and still have the risk of high-altitude falling and mechanical collision.

[0007] Poor mobility: most devices are fixedly installed or bulky, rely on large transportation tools for carrying, and cannot be flexibly placed according to the use scene (such as adjusting the device layout during the peak season of an amusement park or temporarily replacing the training site in a training institution), and the practicability is greatly reduced.

[0008] In summary, there is no aerial device in the prior art that simultaneously satisfies the requirements of "safe operation at ultra-low altitude, vertical take-off and landing, portability, and integration of amusement and teaching", and there is a significant technical gap in the market. SUMMARY

[0009] The purpose of the present application is to provide an ultra-low altitude vertical take-off and landing aerial amusement and teaching integrated device, which controls the flight height through a limiting structure, realizes vertical take-off and landing by combining a multi-rotor aerodynamic device, has the advantages of safety, portability and multifunction, can greatly improve the safety and functionality, realizes the combination of "amusement experience" and "practical teaching", and meets the use requirements of high safety, small take-off and landing space and convenient movement, thereby filling the gap of aerial devices integrating amusement and teaching.

[0010] To achieve the above purpose, the present application designs an ultra-low altitude vertical take-off and landing aerial amusement and teaching integrated device through the following technical scheme, the core structure of which includes a flight cabin, a limiting rod and a base, and the functions, connection relationship and optimization design of each component are as follows: 1. Main structure connection: a penetrating hole is arranged in the middle position of the flight cabin in the vertical direction, the flight cabin is sleeved on the limiting rod through the penetrating hole, the lower end of the limiting rod is fixedly connected with the base, a vertical support structure of "base-limiting rod-flight cabin" is formed, and the overall stability of the device is ensured.

[0011] The limiting rod is made of high-strength material, can be a light shaft, the material can be stainless steel or chromium-plated bar, the light shaft can be a hollow light shaft, the outer diameter is 100-160 mm, the length is set according to the use scene (5-8 m is preferred for amusement scenes, and 8-10 m is preferred for teaching scenes), and the total weight (not less than 500 kg) of the flight cabin and personnel can be borne. The connecting mode of the limiting rod and the base can be fixed connection through a flange and high-strength bolts.

[0012] A height limiting device is installed on the top of the limiting rod, which is composed of an infrared sensor, an electromagnetic limiter and a control module. The maximum rising height can be preset by the control module (5m by default in the amusement scene and 8m by default in the teaching scene). When the flight cabin rises close to the maximum height, the infrared sensor sends a warning signal. If it continues to rise, the electromagnetic limiter will automatically trigger to limit the further rise of the flight cabin, avoiding the risk of running out of control at a high altitude and completely eliminating the risk of over-height operation.

[0013] 2. Flight cabin design: At least two seats are provided in the flight cabin to meet the teaching needs of multiple people experiencing at the same time or "student + instructor"; when two seats are provided, they are distributed in mirror image around the limiting rod to ensure weight balance and avoid tilting of the flight cabin; holes are provided at the corresponding positions of the bottom and top of the flight cabin for passing the limiting rod and ensuring air circulation in the cabin. Batteries are fixed behind the seats to power the equipment. The flight cabin, as the core area for personnel to ride and operate, is made of lightweight carbon fiber composite material. The overall weight of the flight cabin plus the aerodynamic device is controlled between 100-150kg, taking into account strength and portability.

[0014] The flight cabin can select two kinds of shell structures according to the use scene: hemispherical open type: suitable for amusement scene, the cabin body is a frame structure, which can provide an open view and enhance the amusement experience. Closed transparent shell: suitable for teaching scene, using polycarbonate transparent material, light transmittance not less than 90%, which can not only ensure that the personnel in the cabin can observe the external environment, but also can isolate external interference such as wind and rain, dust, etc., and maintain the stability of the cabin environment.

[0015] When a closed transparent shell is used, doors are provided on both sides, which are designed to slide sideways, with an opening width of 0.8-1m for easy access; the holes at the corresponding positions of the bottom and top of the flight cabin are 10-15mm larger in diameter than the limiting rod for passing the limiting rod, and the top hole also ensures air circulation in the cabin to avoid discomfort caused by heat; and it can also adjust the attitude caused by slight unbalanced force.

[0016] The seat is designed with ergonomics, equipped with a safety belt (three-point or five-point, five-point preferred in the teaching scene) and a headrest to improve comfort and safety; lithium battery packs (800-1000Ah capacity, 48V-220V voltage) are fixed behind the seat to power the equipment, and the battery packs are equipped with a fireproof and explosion-proof shell to prevent safety accidents caused by battery short circuit and overheating.

[0017] 3. Air power device: The air power device is installed on the flight cabin, mainly providing vertical take-off and landing power for the super-low-altitude vertical take-off and landing aviation amusement teaching integrated device. The air power device adopts a multi-rotor configuration, specifically including a plurality of power rotor assemblies and rotor arms, and the number and layout of the rotor arms can be adjusted according to the use scene. The power rotor assembly is composed of a motor and a rotor, and is evenly installed around the flight cabin through the rotor arm. The multi-rotor configuration can be arranged at the top or middle of the flight cabin according to the needs. A protective cover is also provided on the power rotor assembly to prevent the rotor from contacting foreign objects or personnel during operation and to improve safety.

[0018] Preferably, a plurality of rotor arms are regularly installed around the top or middle of the flight cabin (if 6 are selected, horizontally distributed with an included angle of 60° between adjacent rotor arms; if 4 are selected, horizontally distributed with an included angle of 90° between adjacent rotor arms), to ensure uniform stress; the power rotor assembly is installed at the outer end of the rotor arm. The power rotor assembly includes a motor and a rotor. The rotor arm is made of high-strength carbon fiber rod, with a diameter of 80-120mm and a length of 1-1.6m; one end of the rotor arm is fixedly connected to the side wall of the flight cabin through a flange, and the other end is installed with the power rotor assembly.

[0019] Preferably, each group of power rotor assemblies contains 2 motors and rotors with opposite directions, which can offset the torque by rotating in opposite directions, while providing vertical lift and horizontal movement power (by adjusting the speed difference of different rotors to achieve horizontal displacement). The power of a single motor is between 10-30kW, the rotating speed is 1500-2000rpm, and the rotor diameter is 1.2-2m, made of carbon fiber.

[0020] Preferably, a protective cover is provided outside the power rotor assembly, which is made of grid-shaped ABS plastic material with a pore size not greater than 50mm, which can prevent the rotor from contacting foreign objects (such as branches, plastic bags) or personnel during operation, greatly improving safety.

[0021] 4. Smooth movement design: To ensure smooth movement of the flight cabin under the limitation of the limiting rod, a linear bearing is installed at the penetration hole of the flight cabin, the outer shell of the linear bearing is fixedly connected to the flight cabin, and the connection mode can adopt flange plus screw fixation, the inner diameter of the linear bearing matches the diameter of the limiting rod, the limiting rod passes through the linear bearing, and the rolling friction of the bearing replaces the sliding friction, reducing the moving resistance to 1 / 5-1 / 10 of the sliding friction, ensuring smooth and stable lifting of the flight cabin. At the same time, the linear bearing has a certain radial offset compensation ability, which can cope with the attitude offset of the flight cabin caused by slight imbalance of weight or air flow disturbance, automatically adjusts the relative position of the flight cabin and the limiting rod, and avoids tilting and jamming.

[0022] 5. Power supply mode: The power supply of the super-low-altitude vertical take-off and landing aviation amusement teaching integrated device is divided into two optional schemes, which are suitable for different use time and scene requirements: Scheme one: battery power. Fix lithium battery pack behind the seat in the flight cabin, directly power the air power device and operation control component, single charge can support the device to run continuously for 0.5-1.5 hours, suitable for short distance movement (such as adjusting the device position in the amusement park or in-field displacement flight experience) and short time operation (such as 10-15 minutes of single amusement experience); the battery pack supports fast charging function, and 0.5 hours of charging can restore 80% of the power.

[0023] Scheme two: ground power supply. Set up ground power supply on the ground (preferably integrate the ground power supply in the base to save space), the ground power supply uses 220V AC mains input, after step-down and rectification, it is supplied to the device through the tethered wire (the length matches the length of the limiting rod, with anti-pulling and anti-electric shock protection functions), which can meet the needs of 24-hour continuous operation of the device, suitable for long time use (such as 4-6 hours of continuous aviation teaching training); the connection end of the tethered wire and the flight cabin uses a waterproof plug to avoid short circuit in rainy days.

[0024] 6. Operation and control component: the operation and control component in the flight cabin is configured differently according to "amusement mode" and "teaching mode", as follows: Joystick: at least one joystick is set in front of a seat (stroke is 50-80mm, operating force is 5-10N), one joystick is set in front of the operator seat in amusement mode, supporting lifting, hovering, horizontal displacement (forward, backward, left and right) and yaw operation; one joystick is set in front of each of the student seat and the instructor seat in teaching mode, the instructor joystick has "priority takeover" function, when the student operation is abnormal, the instructor can obtain the control right of the device immediately by pressing the "takeover button" on the joystick, avoiding danger.

[0025] Navigator: GPS+Beidou dual-mode navigation is adopted, with positioning accuracy of 0.5-2m, which can receive communication signals and locate the device position in real time, and in teaching mode, "simulated flight route" (such as straight flight, turning, flying around point, etc.) can also be preset, the navigator shows the current position and flight route progress information to the student through the display screen, assisting standardized teaching.

[0026] Flight controller: special multi-rotor flight control system (such as Pix flight control) is adopted, with attitude stabilization, automatic hovering and abnormal protection functions, which can detect the flight height, speed and attitude angle parameters of the device in real time, and if the parameters are detected to be out of the safe range (such as inclination angle greater than 15°, speed greater than 5m / s), the power output is automatically adjusted to stabilize the flight attitude; at the same time, "one-key landing" safety function is preset, personnel can control the device to land smoothly at a speed of 0.5-1m / s by pressing the "one-key landing" button on the operation panel.

[0027] Control Panel: A control panel is located next to the control stick, equipped with a display screen (7-10 inches in size, 1280×720 resolution), buttons, and indicator lights. The display screen can show flight parameters (altitude, speed, battery level) and operation prompts (such as "approaching altitude limit" and "please take over control"). The indicator lights use different colors (green: normal operation; yellow: warning; red: malfunction) to indicate the equipment status. The buttons include "power switch", "mode switch", and "one-key landing", making operation convenient.

[0028] 7. Base auxiliary design: The base, serving as the support and foundation for the equipment's movement, adopts a circular steel structure (5-9 mm in diameter and 100-250 mm in thickness), internally filled with concrete counterweights. The total weight of the base is 300-500 kg, enhancing equipment stability and preventing tipping. The auxiliary designs on the base are as follows: The base has four wheels arranged in a circular array around its center. Two of these wheels are omnidirectional (with brakes) and two are directional, allowing the base to move horizontally in any direction. This, combined with the horizontal propulsion of the flight cabin, enables the entire device to move. The wheels are made of polyurethane, which is wear-resistant and quiet, making them suitable for use on various indoor and outdoor surfaces such as cement, asphalt, plastic, and grass.

[0029] Shock-absorbing springs: One large shock-absorbing spring (120-200mm in diameter, 250-400mm in free length) or four shock-absorbing springs (80-100mm in diameter, 200-300mm in free length) are installed between the base and the cabin. When a single large shock-absorbing spring is installed, it is fitted onto the positioning rod. When four shock-absorbing springs are installed, they are symmetrically distributed around the upper surface of the base. The function of the shock-absorbing springs is to buffer the impact force during cabin landing, reducing the impact force to 1 / 3-1 / 5 of that without springs, improving passenger comfort, and reducing wear on equipment components.

[0030] Collision prevention and range limitation: The difference between the diameter of the base and the maximum size of the aerodynamic device when all rotors are rotating is not less than 0.5m, ensuring that when multiple devices are operating in the same area, even if the bases collide, the rotors will not collide, avoiding the risk of collision when multiple devices are used in concert; in addition, the base is equipped with a steel wire rope fixing ring, one end of which is fixed to the fixing ring, and the other end is connected to a ground anchor (which can be buried in the ground or fixed to a heavy object). The length of the steel wire rope can be set according to the usage scenario (preferably 10-15m) to limit the operating range of the equipment and further improve safety.

[0031] Integrated functions: the base can be integrated with ground power supply (as described in the scheme of embodiment 2), battery charging module (which can charge the battery pack in the flight cabin) and storage space (for storing maintenance tools, safety protection supplies, etc.), high degree of functional integration, saving space Compared with the prior art, the beneficial effects of the present application are as follows: 1. Functional integration: switchable "teaching mode" (double operating rod, instructor can take over) and "recreation mode" (single operating rod + passenger seat), which can meet the needs of recreation experience and aviation teaching, users can practice through the operating rod, which can not only obtain the real vertical take-off and horizontal displacement body feeling, but also master the basic aviation operation skills, solving the problem of single function of traditional equipment.

[0032] 2. High safety: the flight height is limited by the limiting rod + height limiting device, the power rotor assembly is provided with a protective cover, the base diameter is greater than the maximum rotation size of the rotor, the landing impact is buffered by the shock absorbing spring, the running range is limited by the steel wire rope, and multiple safety designs avoid high-altitude risks, mechanical injuries and multiple equipment collision risks, which are suitable for recreation scenes with low-altitude personnel.

[0033] 3. Convenient and stable: the base is provided with universal wheels to support flexible movement of the equipment, facilitating flight horizontal displacement and ground carrying movement; the power supply mode can be flexibly selected, and the two power supply modes are suitable for different use time requirements, which are practical; the linear bearing ensures smooth lifting of the flight cabin; the shock absorbing spring improves the riding comfort and forced landing experience. The mirror image distribution of the seats in the flight cabin and the uniform arrangement of the multi-rotors ensure force balance and good stability.

[0034] 4. Wide application scenarios: it can be used in amusement parks, popular science venues, aviation training institutions and other places, without the need for large open spaces, reducing the space requirements of the use scene. DETAILED DESCRIPTION
