Description

Technical Field

[0001] This utility model relates to the field of flying saucer toy technology, and in particular to a flying saucer toy. Background Technology

[0002] Originally, flying saucer toys were manually thrown discs made of soft foam or plastic. Their ingenious aerodynamic design allowed them to glide smoothly through the air with a simple flick of the wrist. This spinning arc is a vivid image from countless childhood memories, representing the simplest and most direct outdoor fun—running, chasing, cooperating, and laughing. With technological advancements, flying saucer toys have entered their intelligent era. The emergence of electrically powered hovering flying saucers has brought science fiction into reality. Built-in motors and sensors allow them to levitate and move gracefully indoors, free from manual throwing, via remote control or even gestures. Their stable flight and soft lighting make them resemble a miniature UFO that truly lands in the palm of your hand, greatly satisfying people's, especially teenagers', desire to explore cutting-edge technology. These toys are no longer limited to the outdoors; they extend the joy of flight to every corner of the home, becoming a highly entertaining and interactive technological toy.

[0003] UFO toys are common recreational products that achieve flight by generating lift through rotation or airflow. Existing UFO toys typically employ a single-layer disc structure with several blades along the edge, rotating via manual throwing or a motor. However, this structure suffers from insufficient flight stability; the disc is prone to deflection or tumbling during flight, affecting the controllability of its trajectory. Furthermore, the single-layer disc structure is susceptible to deformation upon impact, altering the blade angles and further reducing flight performance. Therefore, existing UFO toys require structural improvements to enhance flight stability and resistance to deformation. Utility Model Content

[0004] This invention provides a flying saucer toy to solve the technical problems of insufficient flight stability, poor controllability of flight trajectory, and easy deformation upon impact that affect flight performance caused by the single-layer saucer structure of existing flying saucer toys.

[0005] To solve the above problems, the flying saucer toy provided by this utility model adopts the following technical solution: A flying saucer toy includes an upper saucer, a lower saucer, a central connecting post, and multiple blade assemblies. The upper and lower saucers are two circular discs of the same diameter, arranged parallel to each other vertically. The central connecting post extends vertically in the vertical direction, with its top end fixedly connected to the center of the upper saucer and its bottom end fixedly connected to the center of the lower saucer, thus forming a double-layered saucer structure with an internal cavity together with the upper and lower saucers. Multiple blade assemblies are evenly distributed circumferentially and fixedly arranged in the edge area between the upper and lower saucers. Each blade assembly includes a blade mounting seat and a rigid blade. The blade mounting seat has a concave mounting groove with its opening facing the outside of the saucer. The rigid blade is embedded and fixed in the mounting groove, and its airfoil section is fixed at a preset angle of attack. A motor mounting compartment is provided in the central area of ​​the upper surface of the upper saucer, and a drive motor is fixedly installed in the motor mounting compartment. The output shaft of the drive motor extends vertically downwards through the upper disc and into the internal cavity of the double-disc structure. A propeller is fixedly connected to the end of the output shaft. An air intake grille is located in the central area of ​​the lower disc, corresponding to the propeller position. Multiple outwardly angled exhaust holes are arranged around the edge of the upper disc. When the drive motor drives the propeller to rotate, outside air is drawn into the internal cavity through the air intake grille of the lower disc, accelerated by the propeller, and then impacts the inner surface of the upper disc upwards. The air is then expelled through the exhaust holes at the edge of the upper disc, thus generating lift and inducing the disc to rotate.

[0006] The rigid blades in the multiple blade assemblies are mounted at a fixed and consistent angle relative to the plane of rotation of the disc, providing additional aerodynamic lift and maintaining flight stability during disc rotation. Both the upper and lower disc bodies are integrally injection molded from a rigid polymer material, with an embedded annular reinforcing skeleton located at the outer edge of the disc to enhance the overall structural strength and resistance to deformation of the disc.

[0007] As a further improvement, the central connecting column is a hollow tubular structure with a wiring channel inside. The power supply wires for the drive motor are led from the upper disc to the lower disc through this wiring channel and connected to a power interface located on the lower surface of the lower disc. A removable battery pack is connected to the power interface.

[0008] As a further improvement, the lower surface of the lower disc is provided with multiple landing feet around the central connecting post. The multiple landing feet are evenly distributed circumferentially, and each landing foot has a cushioning pad attached to its bottom.

[0009] As a further improvement, the motor mounting compartment of the upper disc is equipped with a cover. The cover is detachably connected to the upper disc via a snap-fit ​​mechanism. Multiple ventilation holes are provided in the center of the cover.

[0010] As a further improvement, the blade mounting base is fixedly connected to the lower surface edge of the upper disc and the upper surface edge of the lower disc by bolts.

[0011] As a further improvement, the propeller is a three-bladed propeller with an optimized blade twist angle to meet the airflow acceleration requirements in a confined space.

[0012] As a further improvement, the vents are arranged in a ring array on the upper plate, with the axis of each vent forming a 45-degree angle with the normal direction of the upper surface of the upper plate.

[0013] The beneficial effects of this utility model are as follows: The flyable flying saucer toy of this utility model, through the use of a stable frame composed of a double-layered disc structure arranged vertically and horizontally with a central connecting column, significantly enhances the rigidity and impact resistance of the overall structure, effectively preventing deformation during use. The rigid blade assembly, evenly distributed between the double-layered discs, provides continuous and stable aerodynamic lift during rotation. Combined with the built-in propulsion system consisting of a drive motor, propeller, and specific flow channels, this ensures the stability of the flying saucer toy during takeoff and flight, improving the controllability of its flight trajectory. Its reasonable structural design and clear component connections result in stable flight and high durability. Attached Figure Description

[0020] like Figure 1-2 As shown, this utility model provides a flyable flying saucer toy, the core structure of which is designed to achieve stable flight performance through precise physical construction. The main body of the flying saucer toy includes an upper saucer 1, a lower saucer 2, a central connecting column 3, and multiple blade assemblies.

[0021] Specifically, the upper disc 1 is a regular circular disc-shaped structure with a flat upper surface and edges that curve downwards and extend outwards, forming a rounded circumferential contour. The lower disc 2 is also a regular circular disc-shaped structure with the same diameter as the upper disc 1, and the two are arranged parallel to each other vertically, maintaining a fixed vertical distance. Both the upper disc 1 and the lower disc 2 are integrally molded from a rigid polymer material with high strength, excellent impact resistance, wear resistance, and lightweight properties using a precision injection molding process. To further enhance the overall structural strength and deformation resistance of the discs, an annular reinforcing skeleton 11 is integrally embedded in the outer edge region of both the upper disc 1 and the lower disc 2. The reinforcing skeleton 11 has an annular rib or honeycomb structure, tightly integrated with the disc body material, thus forming a high-strength composite structure that significantly improves the structural stability of the discs under external impact or high-speed rotation.

[0022] The central connecting post 3 extends vertically in the up-down direction, and its main body is a cylindrical or polygonal columnar structure, made of high-strength lightweight metal or composite material. The top end of the central connecting post 3 is precisely fixed to the center of the upper disc 1, usually through threaded connection, riveting, or integral injection molding. The bottom end of the central connecting post 3 is precisely fixed to the center of the lower disc 2, with a connection method similar to the top end. Through the connection of the central connecting post 3, the upper disc 1, the lower disc 2, and the central connecting post 3 together form a robust double-layer disc structure with an internal cavity. This internal cavity provides a protected space for airflow and the installation of internal components. In a preferred embodiment, the central connecting post 3 is a hollow tubular structure with a through-through wiring channel 12 inside. The inner diameter of the wiring channel 12 is sufficient to accommodate the power supply wires of the drive motor 7, allowing the wires to be safely and discreetly led from the upper disc 1 to the lower disc 2 and connected to the power interface 13 located on the lower surface of the lower disc 2.

[0023] Multiple blade assemblies are evenly distributed and fixedly installed along the edge region between the upper disc 1 and the lower disc 2. Each blade assembly includes a blade holder 4 and a rigid blade 5. The blade holder 4 is a one-piece molded structural component, made of a material similar to that of the disc body, or a higher-strength engineering plastic. The blade holder 4 has a recessed mounting groove, the opening of which faces precisely outward of the disc body. Its shape and size match the root cross-section of the rigid blade 5 to achieve a tight fit. The rigid blade 5 is a rigid structural component with a preset airfoil cross-section, made of high-strength lightweight material, such as carbon fiber composite or high-strength engineering plastic. The airfoil cross-section of the rigid blade 5 is fixed at a preset angle of attack. The angle of attack is a fixed angle optimized by aerodynamics, which interacts with the airflow when the disc rotates, generating an upward aerodynamic force. The root of the rigid blade 5 is precisely embedded and firmly fixed in the mounting groove of the blade holder 4, for example, by gluing, snap-fitting, or micro-bolts. The rigid blades 5 in the plurality of blade assemblies have fixed and consistent installation angles relative to the plane of rotation of the disc. This consistent installation angle ensures the balance of direction and magnitude of the aerodynamic force generated by each blade 5 during the rotation of the disc, thereby providing the disc with continuous and uniform additional aerodynamic lift and helping to maintain flight attitude stability. In a preferred embodiment, the blade mounting base 4 is detachably or permanently fixed to the lower surface edge region of the upper disc 1 and the upper surface edge region of the lower disc 2 by a plurality of micro bolts or self-tapping screws, ensuring a rigid structural connection between the blade assembly and the disc body.

[0024] A motor mounting compartment 6 protrudes upwards in the center of the upper surface of the upper disc 1. The shape and size of the inner cavity of the motor mounting compartment 6 are precisely matched with the outer dimensions of the drive motor 7 to ensure a stable installation of the drive motor 7. The drive motor 7 is a miniature high-speed DC brushless motor, whose output shaft extends vertically downwards through the bottom center hole of the upper disc 1 and precisely into the internal cavity of the double-layer disc structure. A propeller 8 is securely connected to the end of the output shaft by means of press fitting, threaded connection, or keyway fit. The propeller 8 is a three-bladed design, and the twist angle of its blades has been precisely aerodynamically optimized to meet the airflow acceleration requirements within the limited space of the internal cavity, ensuring maximum thrust at a given speed. A circular or grid-like air intake grille 9 is provided in the center of the lower disc 2, directly below the propeller 8. The air intake grille 9 consists of multiple evenly spaced slits or holes, and its total area is sufficient to ensure smooth airflow into the internal cavity. The upper disc 1 has multiple outwardly inclined exhaust holes 10 arranged around its edge. The exhaust holes 10 are arranged in a ring array, and the axis of each exhaust hole 10 forms a fixed 45-degree angle with the normal direction of the upper surface of the upper disc 1, so that the exhaust airflow has a certain horizontal component, thereby providing lift and inducing the disc to rotate.

[0025] When the drive motor 7 receives electrical energy from the power interface 13 and drives the propeller 8 to rotate at high speed, air from the external environment is first drawn into the internal cavity of the double-layer disc structure through the air intake grille 9 of the lower disc 2. The drawn-in air is accelerated within the internal cavity by the rotation of the propeller 8, forming an upward high-speed airflow. This high-speed airflow then impacts the inner surface of the upper disc 1, generating an upward reaction force, i.e., lift, on its inner surface. After impacting the inner surface of the upper disc 1, the accelerated airflow flows along the inner surface towards the edge and is finally discharged through multiple outwardly angled exhaust holes 10 at the edge of the upper disc 1. This exhaust method generates vertical lift, and due to the angle of the exhaust holes 10, it also generates a tangential thrust, thereby inducing the entire disc structure to rotate. Through this precise structural layout and airflow channel design, the flying saucer toy achieves stable lift generation and controlled rotational flight.

[0026] To provide a convenient way to replenish energy, the power supply wire of the drive motor 7 is safely led from the upper disc 1 to the lower surface of the lower disc 2 via the wiring channel 12 inside the central connecting post 3. The power supply wire is connected to the power interface 13 here. The power interface 13 is designed as a standardized socket or contact structure, and it is externally connected to a removable battery pack, which typically contains lithium polymer batteries or nickel-metal hydride batteries, which can be easily replaced or charged to provide a continuous power supply for the drive motor 7.

[0027] To ensure the flying saucer toy's stable placement on the ground and provide cushioning protection during landing, multiple landing feet 14 are provided on the lower surface of the lower disc body 2 around the central connecting post 3. These landing feet 14 are evenly distributed circumferentially along the lower disc body 2; for example, three or four feet can be provided to form a stable support surface. The main structure of each landing foot 14 is made of high-strength engineering plastic or rubber, possessing a certain degree of toughness. A cushioning pad 15 is adhered to the bottom of each landing foot 14. The cushioning pad 15 is made of energy-absorbing elastic material, such as soft rubber or silicone, and its thickness and elastic coefficient are optimized to effectively absorb impact energy during landing, protect the flying saucer's main structure from damage, and reduce landing noise.

[0028] A cover 16 is provided on the top of the motor mounting compartment 6 of the upper disc 1. The shape and size of the cover 16 precisely match the opening of the motor mounting compartment 6, forming a smooth outer surface to reduce air resistance. The cover 16 is detachably connected to the upper disc 1 via a snap-fit ​​structure, facilitating the inspection, maintenance, or replacement of the internal drive motor 7. The snap-fit ​​structure is formed by multiple protruding claws on the edge of the cover 16 precisely engaging with multiple grooves on the edge of the opening of the motor mounting compartment 6, ensuring that the cover 16 will not accidentally detach during flight. Multiple heat dissipation holes 17 are provided in the center of the cover 16. The heat dissipation holes 17 are distributed in a grid-like or strip-shaped array, and their total area and distribution position are optimized to effectively dissipate the heat generated by the drive motor 7 during operation to the external environment, maintaining the drive motor 7 within a suitable operating temperature range, thereby ensuring its long-term stable operation and service life.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
