[0040] The following describes in detail, with reference to the accompanying drawings, an embodiment of the biomimetic flying toy of this utility model.

[0041] Reference Figure 1 and Figure 2As shown, the bionic flying toy provided in this embodiment of the present invention includes: a shell 10, two swing wings 20 and a transmission wheel set 30. The two swing wings 20 are pivotally mounted on the shell 10. The transmission wheel set 30 is located inside the shell 10 and includes two meshing sector gears 31. The two sector gears 31 are respectively connected to the two swing wings 20, and drive their respective swing wings 20 to swing synchronously when the two sector gears 31 reciprocate.

[0042] The transmission wheel assembly 30 can be driven by the motor 40, which can be controlled by the circuit module to achieve forward or reverse rotation. If the motor 40 rotates continuously in one direction due to a fault in the circuit module, the sector gear 31 can prevent continuous rotation and better limit the rotation angle during transmission, preventing the swinging stroke of the swinging wing 20 from exceeding the swinging range. The sector gear 31 can better limit the swinging wing 20. As a preferred method, the two swinging wings 20 can be completely symmetrical from left to right, so there is no need to distinguish the left and right directions during assembly, which can better assemble with the sector gear 31 and improve assembly efficiency.

[0043] The bionic flying toy provided by this utility model can drive two swing wings 20 to swing synchronously by reciprocating the two sector gears 31 when the transmission wheel set 30 rotates. This restricts the two swing wings 20 to pivot within the angle range of the two sector gears 31, preventing the swing wings 20 from exceeding their own swing stroke and enabling better self-limitation.

[0044] Reference Figure 3 and Figure 4 As shown, the sector gear 31 has 23-27 teeth, and the teeth occupy 85%-93% of the circumference of the sector gear 31. The number of teeth in the sector gear 31 refers to the number of its teeth. The teeth are arranged along the circumference of the sector gear 31, and the circumference ratio of the teeth can be 90%, so that when the sector gear 31 drives the swing wing 20 to swing, the swing angle of the swing wing 20 can reach 120-150 degrees, thereby improving the swing efficiency of the swing wing 20.

[0045] Furthermore, each sector gear 31 is equipped with a connecting shaft 311, which is connected to the swing blade 20 to drive the swing blade 20 to swing when the sector gear 31 reciprocates. The connecting shaft 311 can be integrally formed with the sector gear 31, allowing it to withstand greater torque during rotation. Optionally, the connecting shaft 311 can be made of metal, such as iron or steel. Using a metal connecting shaft 311 can increase the connection strength between the sector gear 31 and the swing blade 20, thereby improving the swing efficiency.

[0046] Reference Figure 1-2 As shown, the housing 10 includes: a main housing 11, a limiting housing 12, a front housing 13, and a rear housing 14. The limiting housing 12 is located on one side of the main housing 11 and defines a swing groove 15 for the two swing wings 20 to swing. The front housing 13 is fixed to the limiting housing 12 and faces away from the main housing 11, and together with the limiting housing 12, it accommodates the transmission wheel set 30. The rear housing 14 is located on the other side of the main housing 11 and together with the main housing 11, it defines a receiving cavity.

[0047] In this embodiment, the main shell 11, the limiting shell 12, the front shell 13, and the rear shell 14 can be fixed together with screws. During the assembly process, the main shell 11, the limiting shell 12, the front shell 13, and the rear shell 14 can be sequentially fitted together and fixed with screws, making the assembly of the shell 10 more efficient. It is understood that compared with the traditional one-piece molded shell, the traditional one-piece molded shell usually requires a mold slide to achieve demolding, which has low production efficiency. However, this application separates the shell 10 into the main shell 11, the limiting shell 12, the front shell 13, and the rear shell 14, thereby eliminating the need for a mold slide to achieve demolding, improving the overall production efficiency and mold life.

[0048] Reference Figure 2 As shown, the limiting shell 12 has a protrusion 121 that extends toward the main shell 11 and is located below the two swing wings 20. The protrusion 121 abuts against the main shell 11, thereby defining the space between the limiting shell 12 and the main shell 11 as the closed end of the swing groove 15. Furthermore, during the swinging of the swing wings 20, the protrusion 121 can also limit the swinging stroke of the swing wings 20 at the bottom, thus restricting the swinging stroke of the swing wings 20 within the swing groove 15, resulting in a simpler and more stable overall structure.

[0049] Reference Figure 5 As shown, in a preferred embodiment, the inner side of the front housing 13 is provided with two clearance grooves 131, which are located above the two sector gears 31 respectively. The clearance grooves 131 can be arc-shaped, thereby achieving clearance through the clearance grooves 131 while reducing the overall volume, and ensuring that the sector gears 31 operate stably between the front housing 13 and the limiting housing 12.

[0050] Reference Figure 2 The cavity contains a motor 40, which is connected to a transmission wheel assembly 30 to drive the transmission wheel assembly 30 to rotate. The drive shaft of the motor 40 can be extended to connect with the transmission wheel assembly 30, and the motor 40 can be controlled to rotate forward or backward to cause the transmission wheel assembly 30 to drive the swinging vane 20 to swing up and down during operation. In a preferred embodiment, the motor 40 can rotate at 11,000 rpm to ensure sufficient motor speed while reducing its size.

[0051] Reference Figure 3 and Figure 4 As shown, the transmission gear set 30 also includes: a driving gear 32, a first driven reduction gear 33 and a second driven reduction gear 34. The driving gear 32 is connected to the motor 40; the first driven reduction gear 33 meshes with the driving gear 32 for transmission; the second driven reduction gear 34 meshes with the first driven reduction gear 33 and one of the sector gears 31 respectively.

[0052] In this embodiment, the first driven reduction gear 33 and the second driven reduction gear 34 can be double gears. Double gears are made of two independent gears that are coaxially integrated, which can increase their torque and speed and save overall installation space. It can be understood that the maximum transmission ratio of the transmission gear set 30 is 1 / 28.6. For example, the transmission ratio between the driving gear 32 and the first driven reduction gear 33 is 1 / 28.6. The first driven reduction gear 33 and the second driven reduction gear 34 can also be 1 / 28.6. The transmission ratio between the second driven reduction gear 34 and the sector gear 31 can also be 1 / 28.6. This can ensure the output torque of the transmission gear set 30 and increase its service life when the motor 40 is working, thereby improving the swing efficiency of the swing wing 20.
