[0036] Figure 1 and Figure 2 The illustration shows a toy aircraft 10 according to some embodiments of the present invention. The toy aircraft includes a body 1, a flight device 2, and a control device 3, with the flight device 2 and control device 3 respectively mounted on the body 1. Understandably, the body 1 has an overall sword shape and serves to support and mount the flight device 2 and control device 3. The flight device 2 provides the power required for flight during operation. The control device 3 controls the flight device 2, enabling the body 1 to fly at a predetermined speed, predetermined altitude, and predetermined direction.

[0037] like Figures 1 to 5As shown, the main body 1 includes a sword blade 11, a first wing 12, a second wing 13, and a sword hilt 14. The first wing 12 and the second wing 13 are symmetrically arranged on the sword blade 11, and the sword hilt 14 is arranged on the sword blade 11. Each of the four components—the sword blade 11, the first wing 12, the second wing 13, and the sword hilt 14—has a receiving hole 11a.

[0038] The flight device 2 includes a cross bracket 21, four flight motors 22 and four flight blades 23. The cross bracket 21 has four mounting ends 211. The cross bracket 21 is mounted on the main body 1. The four mounting ends 211 are exposed in each of the receiving holes 11a. The four flight motors 22 are mounted on each of the mounting ends 211. The four flight motors 22 are connected to the four flight blades 23.

[0039] The control device 3 includes a power supply 31 and a circuit board 32. The power supply 31 is located at the center of the cross bracket 21, and the circuit board 32 is located on the cross bracket 21. The circuit board 32 is electrically connected to the power supply 31 and each flight motor 22. A remote control module is provided on the circuit board 32.

[0040] Understandably, the symmetrical first wing 12 and second wing 13 can make the center of gravity of the main body 1 tend to be in the middle, which is beneficial to improving the flight stability of the product. The blade 11 and the hilt 14 are located in the same straight line extension direction to make the center of gravity tend to be in the middle.

[0041] The cross-shaped support 21 of the flight device 2 is exposed in four receiving holes 11a through four mounting ends 211, allowing the four flight motors 22 to be fixed to the extensions of each mounting end 211. The four flight blades 23 are independently driven by their corresponding flight motors 22, and their function is to achieve flight attitude adjustment through multi-axis independent thrust control. The central convergence structure technology of the cross-shaped support 21 optimizes the weight distribution of the power system. The power supply 31 is fixed at the center of the cross-shaped support 21, which lowers the center of gravity of the aircraft and further improves the flight stability of the product. The remote control module on the circuit board 32 is existing technology; the remote control module allows users to remotely control the flight of the product, improving ease of use.

[0042] Furthermore, the main body 1 can be configured to be made of plastic material.

[0043] Furthermore, the main body 1 can be made of metal. In this embodiment, the antenna unit of the communication module can be configured to be arranged along the axial direction of the blade 11, thereby minimizing the interference of the metal structure on the communication quality and improving the operability of the product.

[0044] like Figures 3 to 5As shown, in some embodiments of the toy aircraft 10, the flight device 2 also includes four slot covers 24; four wire grooves 212 are provided on the cross bracket 21, each wire groove 212 is connected to each mounting end 211 in a one-to-one correspondence, the length extension directions of each wire groove 212 converge at the center of the cross bracket 21, the four slot covers 24 are respectively covered on the four wire grooves 212, and each slot cover 24 is respectively exposed in each receiving hole 11a.

[0045] Understandably, the cable tray 212 extends radially towards the center along the four mounting ends 211 of the cross bracket 21, achieving the shortest possible connection between the flight motor 22 and the control device 3. At the same time, the cable tray 212 can also protect the wiring and improve the durability of the product.

[0046] The cover 24 protects the portion of the wire trough 212 exposed within the receiving hole 11a, preventing foreign objects or liquids from entering the wire trough 212 through the receiving hole 11a. Simultaneously, the cover 24 shields the exposed portion of the wire trough 212, maintaining the integrity of the surface contour of the body 1 and preventing airflow disturbance.

[0047] like Figures 3 to 5 As shown, in some embodiments of the toy aircraft 10, the flight device 2 further includes four fixing frames 25, which are respectively disposed on the four mounting ends 211, and are respectively aligned with the walls of the four receiving holes 11a.

[0048] Understandably, each fixing frame 25 is respectively fitted onto the outside of the mounting end 211 of the cross bracket 21. In this way, the axial alignment of the flight motor 22 can be accurately achieved through the dual positioning constraint of the mounting end 211 and the receiving hole 11a. At the same time, the annular support characteristics of the fixing frame 25 can be used to disperse the vibration stress generated during the operation of the motor.

[0049] In some embodiments of the toy aircraft 10, the toy aircraft also includes a remote controller, which is communicatively connected to the remote control module.

[0050] Understandably, the remote controller establishes a data link with the remote control module on the circuit board 32 through a preset communication protocol, so that the user can remotely send remote control information to the remote control module through the remote controller, and then control the operation of each motor through the circuit board to achieve flight control.

[0051] like Figure 5 As shown, in some embodiments of the toy aircraft 10, each mounting end 211 is provided with a mounting hole 213, and the four flight motors 22 are respectively arranged in the four mounting holes 213.

[0052] Understandably, the diameter of the mounting hole 213 is adapted to the outline of the flight motor 22 housing, thereby enabling the positioning and installation of each flight motor 22, and then ensuring the position of each flight blade 23 through the flight motor 22, ultimately ensuring that the thrust generated by the rotation of each flight blade 23 meets the predetermined design requirements.

[0053] like Figure 4 and Figure 5 As shown, in some embodiments of the toy aircraft 10, the cross bracket 21 includes a battery slot 214, a first connecting arm 215, a second connecting arm 216, a third connecting arm 217 and a fourth connecting arm 218. The first connecting arm 215 and the second connecting arm 216 are symmetrically arranged on the battery slot 214, and the third connecting arm 217 and the fourth connecting arm 218 are respectively arranged on the battery slot 214.

[0054] The third connecting arm 217 and the fourth connecting arm 218 are located in the same straight line direction, the first connecting arm 215 and the second connecting arm 216 are located in the same straight line direction, and the power supply 31 is located in the battery slot 214.

[0055] It should be noted that, for the sake of brevity, the term "arm body" may be used to refer to the first connecting arm 215, the second connecting arm 216, the third connecting arm 217, and the fourth connecting arm 218.

[0056] Understandably, the first connecting arm 215 and the second connecting arm 216 are symmetrically distributed on both sides of the battery compartment 214 and arranged collinearly, while the third connecting arm 217 and the fourth connecting arm 218 are symmetrically distributed on the other two sides of the battery compartment 214 and extend collinearly. The axes of the two sets of arms are orthogonal, forming a cross configuration. The battery compartment 214 is located at the intersection of the four connecting arms, and its cavity shape matches the shape of the power supply 31. In this way, the two orthogonal sets of arms can enhance the torsional stiffness of the cross support 21 and also balance the torque transmission path of each flight motor 22.

[0057] like Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments of the toy aircraft 10, the flight device 2 further includes several fixing components 27. The fixing components 27 include fixing heads 271, fixing posts 272 and fixing bolts. Each fixing head 271 is inserted into the main body 1, each fixing post 272 is set on the cross bracket 21, and each fixing bolt is correspondingly inserted through each fixing post 272 and correspondingly screwed into each fixing head 271.

[0058] Understandably, the fixing head 271 is inserted into a pre-drilled hole on the main body 1, the fixing post 272 is vertically welded to the surface of the cross bracket 21, and the fixing bolt 273 passes through the fixing post 272 and is threadedly connected to the fixing head 271. Alternatively, the fixing post 272 can be configured to be glued, snap-fitted, or integrally molded onto the cross bracket 21. Countersunk holes can be provided on the fixing post 272 to accommodate the fixing bolt, preventing it from being exposed on the product's exterior. This ensures the product's surface flatness and avoids the exposed bolt affecting airflow during flight.

[0059] Furthermore, in some embodiments of the toy aircraft 10, the various fixed components 27 can also be configured symmetrically on the body 1, thereby further centralizing the center of gravity of the product and improving the flight stability of the product.

[0060] like Figure 6 and Figure 7 As shown, in some embodiments of the toy aircraft 10, each fixing head 271 has a fixing angle 2711 at its end, and the fixing angle 2711 is detachably inserted into the body 1.

[0061] Understandably, after the fixing head 271 is inserted into the body 1, the fixing angle 2711 will be locked with the body 1, thereby preventing the fixing head 271 from rotating when the fixing bolt is rotated and tightened, thus ensuring that the fixing component 27 can securely connect the cross bracket to the body 1.

[0062] like Figures 3 to 5 As shown, in some embodiments of the toy aircraft 10, the control device 3 further includes a control switch 33 and a control panel 34. The control switch 33 is disposed on the circuit board 32, and the control panel 34 is provided with a spring arm 341. The spring arm 341 is provided with a power button 342. The control panel 34 is disposed on the body 1, and the power button 342 abuts against the control switch 33. The control switch 33 is exposed on the body 1.

[0063] Understandably, users can perform corresponding operations by pressing the power button 342, which allows the power button 342 to press against the control switch 33, thereby switching the on / off state of the control switch 33. The control panel 34 serves to support the spring-loaded arm 341, which has a certain spring-loaded capability, so that the power button 342 can automatically reset after being pressed by the user.

[0064] It should be noted that the control panel 34, the spring retaining arm 341, and the power button 342 can be configured as an integral molding structure, thereby improving assembly efficiency, improving the connection reliability between the spring retaining arm 341 and the control panel 34, and improving the durability of the control device 3.

[0065] like Figures 2 to 4 As shown, in some embodiments of the toy aircraft 10, the first wing 12, the second wing 13, and the hilt 14 are all integrally formed on the blade 11.

[0066] Understandably, the first wing 12, the second wing 13, the hilt 14, and the blade 11 are made together by integral molding, which can improve the consistency of the product and at the same time greatly eliminate the assembly gap between the various assembly parts of the main body 1.

[0067] like Figure 4 As shown, in some embodiments of the toy aircraft 10, the main body 1 has a mounting groove 15, and the cross bracket 21 is disposed in the mounting groove 15.

[0068] Understandably, the contour of the mounting groove 15 matches the contour of the cross bracket 21. That is, after the cross bracket 21 is aligned and assembled in the mounting groove 15, the groove wall of the mounting groove 15 will fit tightly with the cross bracket 21. At the same time, it also avoids the cross bracket 21 protruding too much outside the mounting groove 15, that is, it avoids the cross bracket 21 forming an excessive amount of protrusion relative to the body 1, improves the surface flatness of the product, and helps to improve the flight stability of the product.

[0071] Secondly, by embedding the entire flight blade inside the body and installing the flight blade along with the flight motor in the receiving hole, a wrap-around protective structure is formed, reducing the probability of the blade coming into contact with external objects during flight, thereby reducing the vulnerability rate of the flight blade.
