Furthermore, the rear rotor assembly structure 4 effectively counteracts the anti-torque force generated during the operation of the front rotor assembly structure 3, further enhancing the overall device's operational stability and functional practicality. Specific configurations are as follows:

[0056] Please refer to Figures 1 to 3 The assembly frame structure 1 includes a frame body 11, a positioning base plate 12, and an assembly groove 13; wherein, the bottom of the frame body 11 is detachably fixedly provided with the positioning base plate 12, and an assembly groove 13 is formed between the frame body 11 and the positioning base plate 12; the indexing base structure 2 is fixedly assembled in the assembly groove 13, and is used to effectively serve as the indexing base for the front shaft rotor assembly structure 3 and the positioning base for the rear shaft rotor assembly structure 4 through the cooperation of the assembly groove 13 and the indexing base structure 2.

[0057] Specifically, the front axle rotor assembly structure 3 is provided in two sets. Each set of the front axle rotor assembly structure 3 includes a front axle extension arm 31, a front axle adapter 32, a front axle mounting base 33, a front axle drive motor 34, and a front axle rotor 35. The two sets of front axle extension arms 31 extend symmetrically towards both sides of the frame body 11, and each set of front axle extension arms 31 is equipped with a front axle adapter 32 and a front axle mounting base 33 at both ends along its extension direction. The two sets of front axle extension arms 31 are respectively and positionably connected to both sides of the indexing base structure 2 via the front axle adapter 32. The base of the front axle drive motor 34 is fixedly mounted on the front axle mounting base 33 of the two sets of front axle extension arms 31, and the kinetic energy output ends of the two sets of front axle drive motors 34 are both facing upwards; the two sets of front axle rotors 35 are respectively driven and mounted on the kinetic energy output ends of the two sets of front axle drive motors 34, and the two sets of front axle rotors 35 are arranged in opposite directions based on the rotation direction of the front axle drive motors 34; this is to achieve the balance of the two sets of front axle rotor assembly structures 3, and also to make the expandable angle range between the two sets of front axle rotor assembly structures 3 larger based on the three-axis architecture, thereby making it easier to ensure the overall forward visibility layout of the frame.

[0058] The rear axle rotor assembly structure 4 is a single unit, and includes a rear axle extension arm 41, a rear axle mounting base 42, a first rear axle drive motor 43, a first rear axle rotor 44, a second rear axle drive motor 45, and a second rear axle rotor 46.

One end of the rear axle extension arm 41 along its extension direction is fixedly mounted to the indexing base structure 2, and the rear axle extension arm 41 extends to the rear of the frame body 11 after passing through at least two sets of limiting blocks 14. The side of the rear axle mounting base 42 is fixedly mounted to the other end of the rear axle extension arm 41, and the top and bottom of the rear axle mounting base 42 correspond one-to-one with the base of the first rear axle drive motor 43 and the second rear axle drive motor, respectively. The base components of the rear axle drive motor 43 are fixedly connected. The kinetic energy output end of the first rear axle drive motor 43 faces upward, and the kinetic energy output end of the first rear axle drive motor 43 is connected to the first rear axle rotor 44 via a transmission assembly.

The first rear axle rotor 44 and the second rear axle rotor 46 are arranged in opposite directions based on the rotation direction of the rear axle drive motor. This arrangement ensures the predetermined balance of the frame through the rear axle rotor assembly structure 4, and also helps to counteract the counter-torque of the two sets of front axle rotor assembly structures 3 during operation by cooperating with the first rear axle rotor 44 and the second rear axle rotor 46, further improving the overall operational stability and functional practicality of the device.
