Description

TECHNICAL FIELD

[0001] The utility model relates to the field of toys, especially toy airplanes. BACKGROUND

[0002] The current toy airplanes on the market generally adopt the power structure of motor driving propeller, and realize the flight function through the thrust generated by the high-speed rotation of the propeller. Such design is widely used in micro unmanned aerial vehicles, foam airplanes, hand-throwing electric toys and other products, and its core principle is to drive the propeller to cut the air to form a pressure difference, thereby generating propulsion.

[0003] However, the existing toy airplanes still have certain deficiencies:

[0004] Firstly, the propeller is usually open, that is, the propeller is directly exposed to the external environment; thus, when the propeller rotates, the airflow will diverge radially along the blade (especially the tip vortex effect), resulting in a large amount of kinetic energy dissipation and a significant reduction in the effective thrust of the toy airplane;

[0005] Secondly, the exposed propeller is prone to deformation due to collision, and the high-speed rotating blade has a risk of scratching, and foreign matters such as sand and debris are easy to be sucked into the blade, causing failure;

[0006] In addition, external airflow disturbance (such as crosswind) will destroy the stability of the propeller flow field, causing the flight trajectory to deviate or even lose control, and the flight stability of the product is very poor. INVENTION CONTENTS

[0049] Figures 1 to 7 The toy airplane 10 in some embodiments of the present application is shown, which includes a fuselage 1, a power supply assembly 2, a flight assembly 3 and a power assembly 4. The fuselage 1 is used to mount and support the remaining assemblies and parts. The power supply assembly 2 is arranged on the fuselage 1, and the power supply assembly 2 is used to provide electric energy. The flight assembly 3 is arranged on the fuselage 1, and the flight assembly 3 is used to guide airflow, so that the toy airplane 10 can fly. The power assembly 4 is arranged on the flight assembly 3, and the power assembly 4 is used to provide thrust when working.

[0050] As shown in Figures 1 to 8 The flight assembly 3 includes two wings 31, which are symmetrically arranged on the fuselage 1.

[0051] The power assembly 4 includes two air ducts 41, two supports 42, two motors 43, and two propeller blades 44. The two air ducts 41 are correspondingly mounted on the two wings 31, the two supports 42 are correspondingly mounted inside the two air ducts 41, the two motors 43 are correspondingly mounted inside the two air ducts 41, and the two propeller blades 44 are correspondingly located inside the two air ducts 41. The two motors 43 are correspondingly connected to the two propeller blades 44, and the two motors 43 are electrically connected to the power supply assembly 2. The motors 43 drive the propeller blades 44 to rotate, thereby driving the propeller blades 44 to draw gas in from the large-diameter end 415 of the air duct 41 and discharge it through the small-diameter end 416.

[0052] Understandably, the power supply component 2 is located inside the body 1. The power supply component 2 can be configured to include a battery and wires. The battery is electrically connected to the motor 43 of the power component 4 through the wires to provide a continuous and stable power supply for the entire system.

[0053] The flight component 3 includes two wings 31, which are symmetrically arranged on both sides of the fuselage 1. The two wings 31 are used to guide airflow to generate lift, thereby achieving flight attitude control and stability maintenance of the toy airplane 10.

[0054] The two air guide ducts 41 have hollow internal structures, and both air guide ducts 41 are used to guide the direction of airflow. A bracket 42 is fixed to the inner wall of the air guide duct 41. The bracket 42 supports the installation of the motor 43 and the flight propeller 44. A shock-absorbing structure can be added to the bracket 42 to reduce vibration transmission during motor 43 operation. The output shaft of the motor 43 is driven by the flight propeller 44. When the motor 43 is powered on, it drives the flight propeller 44 to rotate at high speed. The airflow generated by the rotating flight propeller 44 is drawn in through the large-diameter end 415 of the air guide duct 41, accelerates along the inner wall contour of the air guide duct 41, and is discharged from the small-diameter end 416 of the air guide duct 41, forming directional thrust.

[0055] It should be noted that the modular design of the power component 4 facilitates maintenance and replacement. The connection between the power component 4 and the wing 31 can be directly disassembled and reassembled, which improves the assembly and production efficiency and the ease of maintenance of the power component 4.

[0056] like Figures 3 to 5 As shown, in some embodiments of the toy airplane 10, each air duct 41 includes a cylinder 411 and a connector 412. The connector 412 is disposed on the cylinder 411, and the two connectors 412 are connected to the two wings 31 in a one-to-one correspondence.

[0057] It can be understood that the barrel 411 is a hollow tubular structure, the inside of the barrel 411 forms an airflow passage with a gradually changing cross-sectional area, and the barrel 411 is used to guide the airflow to be introduced from the large-diameter end 415 and discharged from the small-diameter end 416. The connecting piece 412 is arranged on the outer wall of the barrel 411, specifically at the connecting end of the barrel 411 and the wing 31, and the structure design is matched with the mounting position of the wing 31. The two connecting pieces 412 are fixedly connected with the corresponding wings 31 through fixing structures (such as bolts, buckles or welding), so that the air guide barrel 41 is stably mounted at the specified position of the wing 31. The arrangement of the connecting piece 412 realizes the mechanical connection of the air guide barrel 41 and the wing 31.

[0058] As shown in Figure 4 and Figure 5 , in some embodiments of the toy airplane 10, each air guide barrel 41 further includes three threaded connecting pieces;

[0059] The barrel 411 is provided with three alignment columns 4111, each of which is provided with a connecting screw hole 4112. The connecting piece 412 is provided with three alignment holes 4121 and three countersunk holes 4122, and each countersunk hole 4122 is in one-to-one correspondence with each alignment hole 4121.

[0060] Among them, each alignment column 4111 is inserted into each alignment hole 4121 in one-to-one correspondence, each threaded connecting piece is inserted into each countersunk hole 4122 in one-to-one correspondence, and each threaded connecting piece is screwed into each connecting screw hole 4112 in one-to-one correspondence.

[0061] It should be noted that during assembly, the alignment column 4111 is inserted into the alignment hole 4121 of the connecting piece 412 to achieve preliminary positioning of the barrel 411 and the connecting piece 412. Then, the three threaded connecting pieces (such as bolts) are sequentially inserted through the countersunk holes 4122 and screwed into the corresponding connecting screw holes 4112, thereby firmly connecting the connecting piece 412 and the barrel 411. This structure ensures the assembly accuracy and vibration resistance of the overall structure of the air guide barrel 41 through multi-point positioning (alignment of the alignment column 4111 and the alignment hole 4121) and multi-point locking (threaded connecting piece fixation).

[0062] As shown in Figure 5 and Figure 6 , in some embodiments of the toy airplane 10, one of the connecting pieces 412 is provided with a left wing profile surface 311, and the other connecting piece 412 is provided with a right wing profile surface 312.

[0063] The left wing profile surface 311 is matched with the outer surface of one of the wings 31, and the right wing profile surface 312 is matched with the outer surface of the other wing 31.

[0064] It can be understood that the curved surface profile of the left wing profile surface 311 completely matches the outer surface shape of the corresponding wing 31, and the right wing profile surface 312 also matches the outer surface shape of the other wing 31. Through the structural design of the profile surface, the connecting piece 412 can closely fit the surface of the wing 31, reduce the structural gap after assembly, optimize the smoothness of the airflow passing through the connecting part of the air duct 41 and the wing 31, reduce the aerodynamic resistance and improve the overall appearance coordination.

[0065] As shown in Figures 3 to 5 In some embodiments of the toy airplane 10, the air duct 41 further comprises a front hoop 413 and a tail hoop 414 in each air duct 41, the front hoop 413 is arranged at the large diameter end, and the tail hoop 414 is arranged at the small diameter end.

[0066] It can be understood that the front hoop 413 and the tail hoop 414 are both annular structures, which are fixed to the corresponding end of the cylinder body 411 by fasteners such as screws or buckles. The function of the front hoop 413 is to strengthen the structure at the entrance of the large diameter end 415 to prevent the cylinder body 411 from being radially deformed when the airflow is sucked at high speed; the tail hoop 414 is used to support the outlet area of the small diameter end 416 to ensure the rigidity of the cylinder body 411 and the stability of the airflow guiding direction when the airflow is accelerated to be discharged. In this way, the setting of the front hoop 413 and the tail hoop 414 can further improve the flight stability of the product.

[0067] As shown in Figure 4 and Figure 5 In some embodiments of the toy airplane 10, a limiting step 4113 is arranged in the air duct 41, and a positioning groove 4114 is arranged on the limiting step 4113;

[0068] In each bracket 42, the bracket 42 comprises a fixing ring 421, a core column 422 and a plurality of connecting arms 423, the fixing ring 421 is provided with a limiting lip 4211 and a positioning protrusion 4212 connected to each other, the core column 422 is arranged at the center of the fixing ring 421, one end of each connecting arm 423 is connected to the fixing ring 421, the other end of each connecting arm 423 is connected to the core column 422, and the motor 43 is arranged on the core column 422;

[0069] Among them, the fixing ring 421 is inserted into the air duct 41, the limiting lip 4211 abuts against the limiting step 4113, the positioning protrusion 4212 is inserted into the positioning groove 4114, and the front hoop 413 abuts against the limiting lip 4211.

[0070] It can be understood that the limiting step 4113 in the air duct 41 provides an axial limiting reference for the fixing ring 421 of the support 42 through its step surface, preventing the support 42 from axially moving in the air duct 41. The positioning groove 4114 cooperates with the positioning protrusion 4212 of the fixing ring 421 to realize the circumferential positioning of the support 42, ensuring that the installation angle of the support 42 relative to the air duct 41 accurately matches the airflow guiding requirement.

[0071] The limiting lip 4211 abuts against the limiting step 4113 to form a mechanical stop, avoiding the axial loosening of the support 42 due to the working vibration of the motor 43 or the airflow impact; the positioning protrusion 4212 is inserted into the positioning groove 4114 to realize the quick and accurate installation of the support 42 through shape cooperation, eliminating the influence of assembly deviation on the working stability of the power assembly 4.

[0072] The core column 422 serves as the installation base of the motor 43, for ensuring the stability of the motor 43 when rotating at high speed. The connecting arm 423 connects the fixing ring 421 and the core column 422 through multi-directional distribution (such as star-shaped or ring-shaped layout) to form a fixed frame, dispersing the vibration load of the motor 43 when working and reducing structural deformation.

[0073] As shown in Figure 4 and Figure 5 , in some embodiments of the toy airplane 10, the core column 422 is provided with an installation hole 4221 in the length extension direction.

[0074] It can be understood that the hole wall profile of the installation hole 4221 is matched with the outer profile of the motor 43, thereby ensuring the stability of the motor 43 on the core column 422 and avoiding excessive motor 43 vibration due to too large fitting gap.

[0075] As shown in Figure 4 and Figure 5 , in some embodiments of the toy airplane 10, each support 42 includes three connecting arms 423, which are evenly arranged at equal angles outside the core column 422.

[0076] It can be understood that the three connecting arms 423 arranged in a symmetrical layout disperse the vibration load of the motor 43 when working through multi-directional support, while enhancing the overall rigidity of the support 42, avoiding structural deformation due to local stress concentration, and further ensuring the long-term reliability of the power assembly 4.

[0077] As shown in Figures 1 to 3 , in some embodiments of the toy airplane 10, the flight assembly 3 further includes a tail wing 32 arranged on the fuselage 1.

[0078] Please refer to Figures 6 to 8The toy airplane 10 also includes a wake assembly 5, which includes two movable wing skirts 51, an adjustment motor 52, and an adjustment arm 53. The two movable wing skirts 51 are rotatably connected to opposite sides of the tail 32. The adjustment motor 52 is mounted on the fuselage 1 and is driven by the adjustment arm 53. The adjustment arm 53 is movably connected to the two tail 32 skirts. The adjustment motor 52 drives the adjustment arm 53 to move so that the adjustment arm 53 drives each movable wing skirt 51 to rotate relative to the tail 32.

[0079] Understandably, the two movable wing skirts 51 are connected to both sides of the tail fin 32 via a rotating joint. Their rotation angle is driven by the adjusting arm 53, which can change the direction of the wake and the downforce distribution, thereby correcting the pitch or yaw angle of the toy airplane 10. The output shaft of the adjusting motor 52 directly or indirectly drives the adjusting arm 53 to rotate, and the adjusting motor 52 drives the adjusting arm 53 to move, thereby the adjusting arm 53 drives the movable wing skirts 51 on both sides to rotate.

[0080] like Figure 7 and Figure 8 As shown, in some embodiments of the toy airplane 10, the wake assembly 5 also includes a rotating arm 54, an adjusting motor 52 is connected to the rotating arm 54, and a slot 541 is provided on the rotating arm 54.

[0081] Part of the adjusting arm 53 is inserted into the locking slot 541. One end of the adjusting arm 53 extends to the outside of the fuselage 1 and is rotatably connected to one of the movable wing skirts 51. The other end of the adjusting arm 53 extends to the outside of the fuselage 1 and is rotatably connected to another movable wing skirt 51.

[0082] Understandably, when the rotating arm 54 rotates, it will drive the adjusting arm 53 to move through the locking slot 541, thereby driving the two movable wing skirts 51 to rotate on the tail 32, thus achieving the purpose of adjusting the flight pitch angle of the toy airplane 10.

[0083] Specifically, in some embodiments of the toy airplane 10, the aperture size of the large-diameter end is 29mm to 45mm; the aperture size of the small-diameter end is 18mm to 28mm, and the aperture size of the large-diameter end is larger than that of the small-diameter end.

[0084] It should be noted that by adopting the content of this embodiment, it can be ensured that the air guide duct 41 has good airflow guiding performance, that is, it can ensure that a large amount of airflow can enter the large diameter end and flow quickly to the small diameter end for discharge.

[0085] like Figures 1 to 3As shown, in some embodiments of the toy airplane 10, the toy airplane further comprises three support assemblies 6, each of which comprises a support frame 61 and a sliding wheel 62 rotatably arranged on the support frame 61, wherein two support frames 61 are arranged on the two wings 31 respectively, and the two support frames 61 are symmetrical to each other; and the other support frame 61 is arranged on the fuselage 1.

[0086] It can be understood that the support frame 61 is used to mount the sliding wheel 62 and support the fuselage and the wings. The sliding wheel 62 is connected with the support frame 61 through a rotating shaft and can rotate freely, so as to reduce the frictional resistance when the toy airplane 10 moves on the ground, facilitating manual pushing or automatic cruising (such as ground travel in remote control mode).

[0087] It should be noted that the arrangement of the three support assemblies 6 forms a three-point support structure, thereby effectively preventing the fuselage and the wings from contacting the bottom surface and avoiding unnecessary damage.

[0088] The implementation of the present application has the following beneficial effects:

[0089] The present application relates to a toy airplane, wherein two air guide tubes symmetrically arranged on the wings and flight blades arranged in the air guide tubes are arranged on the toy airplane, so that the flight blades drive gas to flow into the air guide tubes from the large-diameter end and flow out from the small-diameter end, so that the airflow flows in the unchanged space in the air guide tubes, effectively improving the airflow speed and greatly enhancing the effective thrust.

[0090] Secondly, the flight blades are completely arranged in the air guide tubes, so that the air guide tubes form an annular protective structure surrounding the flight blades, thereby avoiding direct contact between the flight blades and external objects and reducing the damage risk of the blades.

[0091] In addition, the two wings are symmetrically arranged, and the independent air guide tubes, motors and flight blade combination structures are correspondingly arranged on each wing, so that the two independently driven flight blades form balanced thrust output, thereby improving the flight stability to a certain extent; and the outer side of the periphery of each flight blade is surrounded by the air guide tube, thereby preventing crosswinds from hindering each flight blade and further ensuring the flight stability of the product.

[0092] The scheme of the present application has been described in detail above with reference to the drawings. In the above-described embodiments, the description of each embodiment has its own focus, and the parts not described in detail in a certain embodiment can be seen in the relevant description of other embodiments.

In addition, it can be understood that the steps in the method of the embodiments of the present application can be adjusted, combined and reduced in sequence according to actual needs, and the modules in the device of the embodiments of the present application can be combined, divided and reduced according to actual needs.
