[0002] With the continuous advancement of technology, amphibious robots have been widely used in fields such as detection and reconnaissance. However, existing amphibious robots typically cannot be separated into their own parts and rely on structural modifications to switch between air and land modes during use. For example, a amphibious robot disclosed in Chinese invention patent application number CN202011274303.4 has the following problems in actual use: it is relatively heavy, has poor maneuverability, and is difficult to adapt to various environments. For instance, in some narrow spaces, the vehicle body needs to move independently to work, at which point the flight part becomes a burden. Also, it cannot meet the needs when it is necessary to perform both ground and high-altitude operations simultaneously. Summary of the Invention

Detailed Implementation

[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Please see the appendix Figures 1 to 5 As shown, this utility model provides a detachable and recoverable amphibious unmanned aerial vehicle 100, which includes a body 1, a vehicle body 2, and a detachment and recovery system 3 disposed between the bottom of the body 1 and the top of the vehicle body 2; wherein, the body 1 is used to achieve high-altitude flight, the vehicle body 2 is used to achieve ground walking, and the detachment and recovery system 3 is used to achieve detachment and recovery functions. The separation and recycling system 3 includes a bracket 31 at the bottom of the body 1, an embedded component 32 at the top of the vehicle body 2, and a data collection device at the bottom of the body 1. The data collection device is used to collect relevant data so that the body 1 and the vehicle body 2 can dock to realize the recycling function. The embedded component 32 is detachably connected to the bracket 31 to realize the separation and recycling function between the body 1 and the vehicle body 2.

[0019] This utility model designs an amphibious unmanned aerial vehicle (UAV) 100 including a separation and recovery system 3 located between the bottom of the fuselage 1 and the top of the vehicle body 2. The separation and recovery system 3 includes a mounting bracket 31 located at the bottom of the fuselage 1, an embedded component 32 located at the top of the vehicle body 2, and a collection device located at the bottom of the fuselage 1. The embedded component 32 is detachably connected to the mounting bracket 31. This allows the UAV 1 to carry the vehicle body 2 to the desired destination for missions during actual use, and also allows the vehicle body 2 to transport the UAV 1 to the desired destination for missions. Furthermore, it allows the airframe 1 and vehicle body 2 to separate and perform their respective tasks. After completing the task, the airframe 1 can be used to recover the vehicle body 2. Therefore, by adopting the technical solution of this utility model, the detection range of the entire land-air amphibious UAV 100 can be effectively increased, making it more flexible and convenient to use. It can adapt well to various different environments and improve the efficiency of task execution. At the same time, after separation, the airframe 1 and vehicle body 2 will not affect each other, that is, they will not become a burden to each other, which can reduce the weight of the airframe 1 and vehicle body 2 when performing their respective tasks.

[0020] In some embodiments of this utility model, both the body 1 and the vehicle body 2 are equipped with a network radio (not shown). During use, both the body 1 and the vehicle body 2 can communicate with the ground control station and the background mission system through their respective network radios.

[0021] In some embodiments of this invention, the data acquisition device includes a camera 331, a depth sensor 332, and a laser rangefinder 333, all of which are located at the bottom of the body 1. In operation, the camera 331 captures real-time images of the vehicle body 2 and the embedded component 32 on top of the vehicle body 2 to determine the position and orientation of the vehicle body 2. The depth sensor 332 collects real-time data on the positional interval between the body 1 and the vehicle body 2. The laser rangefinder 333 assists in measuring the distance between the body 1 and the vehicle body 2 along the vertical direction. Based on the data collected by the camera 331, depth sensor 332, and laser rangefinder 333, the body 1 can be controlled to adjust its horizontal position and flight altitude, ensuring accurate engagement of the mounting bracket 31 with the embedded component 32, thereby enabling the recovery of the separated vehicle body 2.

[0022] In some embodiments of this utility model, the body 1 includes a fuselage 11, four connecting rods 12 connected to the fuselage 11, a first drive motor 13 located at the free end of each connecting rod 12, and a propeller 14 connected to the output end of each first drive motor 13. During operation, the propeller 14 is driven to rotate by each first drive motor 13 to provide lift required for flight of the body 1.

[0023] In one specific embodiment of this utility model, the propeller 14 is a carbon fiber propeller, and the first drive motor 13 is a brushless motor. In a specific implementation of this utility model, the fuselage 11 can be made of carbon fiber composite material, which can ensure overall strength and make the entire fuselage 1 lighter.

[0024] In some embodiments of this utility model, the vehicle body 2 includes a mounting main board 21, supporting side plates 22 located on both sides of the mounting main board 21, a supporting frame 23 connecting the supporting side plates 22 on both sides, and walking drive components 24 disposed at both ends of the supporting side plates 22. The mounting main board 21 is disposed on the top of the supporting frame 23, and the embedded component 32 is disposed on the top of the mounting main board 21. In specific implementations of this utility model, the mounting main board 21, supporting side plates 22, and supporting frame 23 can all be made of carbon fiber composite material. By adopting the above structural design, the overall structure of the vehicle body 2 can be made simpler and lighter, thereby making the entire amphibious unmanned aerial vehicle 100 lighter.

[0025] In one specific embodiment of this utility model, each of the walking drive components 24 includes a second drive motor 241, a reducer 242, and a wheel 243. The second drive motor 241 and the reducer 242 are both located at the ends of the supporting side plate 22. The output end of the second drive motor 241 is connected to the reducer 242, and the wheel 243 is connected to the output end of the reducer 242. The second drive motor 241 is a brushless motor. During operation, the power output by the second drive motor 241 is reduced in speed by the reducer 242, and then the reducer 242 drives the wheel 243 to rotate, thereby enabling the vehicle body 2 to move.

[0026] In one specific embodiment of the present invention, each of the supporting side plates 22 includes two supporting sub-plates 221 spaced apart, the reducer 242 is fixed between the two supporting sub-plates 221, and both supporting sub-plates 221 are connected to the supporting frame 23.

[0027] This utility model, by designing the support side plate 22 to include two support plates 221 spaced apart, can not only ensure the strength of the support side plate 22 and ensure that it is not easily damaged during use, but also facilitate the installation and fixing of the second drive motor 241 and the reducer 242.

[0028] In the first specific embodiment of this utility model, the hanging bracket 31 is an electromagnetic adsorbent, and a pin insertion hole 311 is formed at the bottom of the hanging bracket 31. The embedded part 32 is an iron pin. In specific implementation, this utility model needs to be electrically connected to the battery 15 of the body 1. During actual use, when it is necessary to connect the hanging bracket 31 and the embedded part 32 together, the battery 15 of the body 1 is controlled to supply power to the electromagnetic adsorbent, and the electromagnetic adsorbent can then tightly adsorb the iron pin. When it is necessary to disconnect the hanging bracket 31 from the embedded part 32, it is only necessary to control the battery 15 of the body 1 to stop supplying power to the electromagnetic adsorbent.

[0029] In a second specific embodiment of this utility model, the bottom of the mounting bracket 31 has a pin insertion hole 311, and the inner wall of the pin insertion hole 311 has an L-shaped limiting groove (not shown). The embedded component 32 includes a servo motor (not shown) located on the top of the vehicle body 2 and an embedded pin (not shown) connected to the output end of the servo motor. A limiting protrusion (not shown) is formed on the embedded pin to slide in cooperation with the L-shaped limiting groove. In a specific implementation of this utility model, when it is necessary to connect the mounting bracket 31 and the embedded component 32 together, it is necessary to first control the body 1 to drive the pin insertion hole 311 of the mounting bracket 31 to be inserted into the embedded pin on the top of the vehicle body 2, and then control the servo motor to drive the embedded pin to rotate a certain angle so that the mounting bracket 31 will not detach from the embedded component 32. When it is necessary to separate the mounting bracket 31 from the embedded component 32, it is necessary to first control the servo motor to drive the embedded pin to rotate in the opposite direction a certain angle, and then control the body 1 to drive the pin insertion hole 311 of the mounting bracket 31 to detach from the embedded component 32.

[0030] In practical operation, the amphibious unmanned aerial vehicle 100 of this utility model can, upon receiving a specific mission, transport the airframe 1 to the required location via the vehicle body 2, or fly to the required location via the airframe 1 carrying the vehicle body 2. Upon reaching the specific location, it can use the vehicle body 2 to transport the airframe 1 together to perform the mission, or use the airframe 1 to carry the vehicle body 2 together to perform the mission. It can also separate the airframe 1 from the vehicle body 2 and control the airframe 1 to perform the mission independently, or control the vehicle body 2 to perform the mission independently, or control the airframe 1 and the vehicle body 2 to cooperate in performing the mission.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
