[0002] Current mainstream logistics drone systems transport and deliver packages by air from aircraft, representing a common air transport solution in the logistics field. However, existing technologies have the following problems and drawbacks:

[0003] 1. Poor adaptability to indoor environments. Existing logistics drones rely on open spaces for flight and turning, while indoor spaces are usually small and have complex layouts, which can easily lead to obstructed flight paths and difficulty in turning. In densely populated indoor places, if a drone malfunctions or goes out of control during flight, it can easily cause safety risks to personnel. Therefore, its application in indoor environments is significantly limited.

[0004] 2. Stringent requirements for take-off and landing sites. Existing logistics drones require dedicated and safe take-off and landing sites (such as dedicated helipads or open areas). However, in densely populated urban areas, land resources are scarce, making it difficult to select such sites and resulting in high construction and maintenance costs, which makes it difficult to meet the needs of large-scale applications. Utility Model Content

[0005] Therefore, it is necessary to address the issue that existing logistics drones rely on open spaces for flight and turning, while indoor spaces are typically small and complex, easily leading to obstructed flight paths and difficult turning. In densely populated indoor locations, if a drone malfunctions or goes out of control during flight, it can easily pose a safety risk to personnel. Thus, the application of drones in indoor environments is significantly limited. Logistics drones require dedicated and safe take-off and landing sites, but in densely populated urban areas, land resources are scarce, making site selection difficult and construction and maintenance costs high, which makes it difficult to meet the needs of large-scale applications. To address this problem, an amphibious logistics transportation equipment can be provided that can switch working modes according to the environment: during air transport, the top propeller and the blades of the mechanical limbs work together to provide lift and directional thrust to achieve flight acceleration; when entering indoor or complex ground environments, the top propeller is retracted, and ground transport is completed by wheeled movement or walking on the mechanical limbs, meeting the logistics needs of different scenarios.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: An amphibious logistics transportation equipment, comprising:

They include a planetary reducer in the cabin, a foldable joint driven by the planetary reducer to achieve multi-degree-of-freedom movement, wheels at the ends of the foldable joints, and wheel blades located inside the wheels that can cooperate with the propeller to provide additional power. The wheel blades are driven by the planetary reducer to achieve steering adjustment through the foldable joints.

[0010] Furthermore, the propeller includes a connecting shaft located on the top of the nacelle, a connecting arm located on the connecting shaft, an arc-shaped folding arm pivotally connected to the rotating arm, a servo motor located at one end of the arc-shaped folding arm, and blades located on the output shaft of the servo motor.

[0011] Furthermore, the planetary reducer includes a first planetary reducer fixed to the nacelle and a second planetary reducer connected to the output end of the first planetary reducer.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0028] Please see Figure 1 This embodiment provides an amphibious logistics transportation equipment, which includes a cabin 10, a propeller 20, and mechanical limbs 30.

[0029] Please refer to Figure 2 The cabin 10 is pivotally connected to a door panel 101. The cabin 10 has a cargo space of more than or less than 0.18 cubic meters. The cabin 10 also integrates a top electrical control box 102 for controlling the operation of the propeller 20 and a front and rear drive control box 103 for driving the mechanical limbs 30. The front and rear drive control box 103 includes a front drive control box and a rear drive control box.

[0030] In this embodiment, please refer to Figure 3The propeller 20 has four propellers that can be folded and unfolded and are wrapped around the top of the cabin 10. The propeller 20 has a connecting shaft 201 fixed to the top of the cabin 10. A connecting arm 202 is rotatably mounted on the connecting shaft 201, and an arc-shaped folding arm 203 is pivotally connected to the connecting arm 202. A servo motor 204 is mounted at one end of the arc-shaped folding arm 203. A blade 205 is mounted on the output shaft of the servo motor 204. The top electrical control box controls the arc-shaped folding arm 203 to unfold the propeller 20, and then controls the servo motor 204 to drive the blade 205 to rotate at high speed to achieve flight.

[0031] In this embodiment, please refer to Figure 1 and Figure 4 Four mechanical limbs 30 are provided, symmetrically arranged in pairs on the front and rear sides of the cabin 10. The two mechanical limbs 30 on the front side are driven by the front drive control box, and the two mechanical limbs 30 on the rear side are driven by the rear drive control box. Each mechanical limb 30 includes a planetary reducer 301, a foldable joint 302, a wheel 303, and a wheel area blade 304, all located in the cabin 10. The planetary reducer 301 includes a first planetary reducer 3011 fixed to the cabin 10 and a second planetary reducer 3012 connected to the output end of the first planetary reducer 3011. The foldable joint 302 is connected to the output end of the second planetary reducer 3012. The foldable joint 302 includes a component connected to the output end of the second planetary reducer 3012. The output end of the reducer 3012 is connected to a first joint 3021 and a second joint 3022 pivotally connected to the first joint 3021. The end of the second joint 3022 is provided with a drive motor 3023. The wheel 303 is located on the output shaft of the drive motor 3023. The drive motor 3023 drives the wheel 303 to rotate. The wheel 303 is provided with a blade motor 3024. The wheel area blade 304 is located on the output shaft of the blade motor 3024. The blade motor 3024 drives the wheel area blade 304 to rotate at high speed. The first planetary reducer 3011 and the second planetary reducer 3012 drive the foldable joint 302 to achieve multi-degree-of-freedom motion capability, thereby realizing the steering adjustment of the wheel area blade 304.

[0032] To reduce the weight of the amphibious logistics transport equipment, apart from core power components such as motors and generators, most of the structure of the cabin 10, propeller 20, and mechanical limbs 30 on the equipment is made of carbon fiber materials, which greatly reduces the overall weight of the equipment, improves its mobility and endurance, and when the equipment is stowed, its overall width is less than 0.9m, allowing it to pass through most narrow spaces (such as doorways).

[0033] In air transport mode, after the transported items are placed inside the cabin 10, the door panel 101 is locked. The top electrical control box controls the arc-shaped folding arm 203 of 102 to unfold the propeller 20, and then controls the servo motor 204 to drive the blades 205 to rotate at high speed, causing the cabin 10 to rise and become suspended in the air. After the cabin 10 is suspended in the air, the front drive control box and the rear drive control box control the planetary reducers 301 on the front and rear sides respectively, causing the planetary reducers 301 to drive the foldable joints 302 to rotate, so that the wheels 303 are in a horizontal state. At the same time, the propeller motors 3024 are controlled to drive the propellers to rotate. The high-speed rotation of the propeller blades 304 in the drive wheel area provides additional power for flight. When forward flight or flight attitude adjustment is required, the planetary reducer 301 is controlled to drive the foldable joint 302 to rotate and adjust the angle, thereby making the wheel 303 form an angle, providing additional thrust for the equipment, and assisting in adjusting the flight attitude. The propeller blades 304 in the drive wheel area are mounted on the mechanical limbs 30. The propeller blades 304 in the drive wheel area achieve steering adjustment through the planetary reducer. During flight, they can work with the propeller 20 to provide additional power, enhancing flight stability and power output.

[0034] In ground transport mode, the four propellers 20 are folded up and stored on top of the cabin 10 to reduce space occupation and avoid interference with the surrounding environment. Simultaneously, the front drive control box and the rear drive control box control the planetary reducers 301 on the front and rear sides respectively, causing the planetary reducers 301 to drive the foldable joints 302 to rotate, making the wheels 303 contact the ground. When the ground is uneven or steps are being climbed, the folding and rotation of the foldable joints 302 on each mechanical limb 30 gives the mechanical limb 30 a high degree of freedom of movement, enabling it to climb, enter elevators, and meet indoor operation requirements. When the ground is flat, the drive motor 3023 drives the wheels 303 to rotate, increasing movement speed and reducing energy consumption through wheeled movement. It should be noted that corresponding motors are installed on the first joint 3021 and / or the second joint 3022, enabling the foldable joints 302 to fold and rotate.

[0035] In summary, during the workflow, the amphibious logistics transport equipment can switch operating modes according to the environment: during air transport, the top propeller 20 and the wheel area blades 304 of the mechanical limb 30 work together to provide lift and directional thrust, achieving flight acceleration; when entering indoor or complex ground environments, the top propeller 20 is retracted, and ground transport is completed through wheeled movement or limb walking of the mechanical limb 30, meeting the logistics needs of different scenarios. The combination of mechanical limb 30 + wheel area blades 304 + planetary reducer 301 enables the wheel area blades 304 to have steering capabilities and provide additional thrust, representing a core technological innovation for achieving land-air collaborative operations and improving transport speed.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
