[0002] With the widespread application of drone technology in many fields, such as aerial photography and mapping, agricultural plant protection, power inspection, logistics distribution, and emergency rescue, the operating environment faced by drones is becoming increasingly complex and diverse, which puts higher requirements on their safety and reliability.

[0003] However, in the actual use of drones, they often face various potential risks and hazards. For example, when crossing complex terrain such as woods and mountains, it is easy to collide with obstacles, causing damage to the drone body and key components. In addition, in some special operating environments such as chemical parks and fire scenes, they may be corroded by chemical substances, roasted at high temperatures, and polluted by smoke and dust, which will affect the normal operation and service life of drones.

Through the coordinated use of the first protective frame, the second protective frame and the third protective frame, a barrier is provided for the UAV to resist external collisions from multiple directions, which can effectively absorb and disperse the impact force, reduce direct damage to the UAV fuselage, wings and other key components, and can effectively reduce the risk of damage to the UAV, extend its service life and reduce maintenance costs.

The impact sensors are distributed on the first protective frame, the second protective frame and the third protective frame, which can accurately sense whether the various parts of the drone collide during the flight and the intensity and location information of the collision. The flight control system can quickly judge the damage of the drone based on the data transmitted by the impact sensor, and take corresponding emergency measures, such as adjusting the flight attitude, reducing the flight speed, starting the automatic return program, etc., to minimize the damage caused by the collision accident to the drone and the potential risks to the surrounding environment.

[0027] 3. By adopting an aluminum alloy structure, the first protective frame, the second protective frame and the third protective frame have the characteristics of light weight and high strength, which will not excessively increase the load of the UAV while ensuring the protective performance, which is conducive to maintaining the flight performance of the UAV. In addition, by applying a nano-ceramic coating on the surface of the frame, the nano-ceramic coating has excellent properties such as waterproof, dustproof and corrosion-resistant, which can resist the erosion of chemical substances on the protective frame and the UAV body, ensuring that the UAV can operate normally in harsh natural environments and special industrial environments, and expanding the application scenarios and scope of UAVs.

[0028] 4. By connecting the first protective frame, the second protective frame and the third protective frame into a whole: After being connected into a whole, the appearance of the entire protective mechanism is more coherent and smooth. During the flight of the drone, the air can flow through the protective structure more smoothly. The conical structure of the second protective frame and the arch bridge structure of the third protective frame can better guide the airflow, and work together with the first protective frame to reduce the turbulence and separation of the airflow.

[0042] The temperature sensor 107 and the humidity sensor 108 can monitor the temperature and humidity changes of the surrounding environment of the UAV 5 in real time. When the ambient temperature and humidity exceed the normal working range of the UAV 5, the wireless communication module transmits the data to the flight control system of the UAV, and the flight control system can adjust the flight mission or send an alarm to the operator accordingly, so as to take corresponding measures in time to ensure the safe operation of the UAV 5. The smoke sensor 109 can play an important role in special application scenarios such as fire monitoring. Once smoke is detected in the surrounding environment, the smoke sensor 109 immediately feeds back the signal to the flight control system through the wireless communication module, so that the UAV 5 can respond quickly.

[0044] Furthermore, a plurality of ventilation windows 6 are provided on the first protective frame 201, the second protective frame 301 and the third protective frame 401, and a protective net 7 is fixedly installed inside the ventilation window 6; wherein, a plurality of air holes 206 are opened on the front and rear sides of the first protective frame 201, and air circulation can be promoted through the ventilation windows 6, while providing protection for the UAV 5, the air flow disturbance caused by the protective structure is reduced, the aerodynamic performance of the UAV 5 is optimized, and the stability and maneuverability of the UAV 5 at different flight speeds and postures are ensured. In addition, by fixing the protective net 7 inside the ventilation window 6, foreign objects can be prevented from entering the interior of the UAV 5 through the ventilation window 6, thereby avoiding damage or interference to internal components. The air flow disturbance caused by the protective structure is further reduced through the air holes 206, and the aerodynamic performance of the UAV 5 is optimized.

[0045] Furthermore, the outer sides of the first protective frame 201, the second protective frame 301 and the third protective frame 401 are all fixedly installed with buffer pads 8, which further enhance the buffering effect during collision. The buffer pads 8 can absorb energy through their own elastic deformation at the moment of collision, thereby reducing the damage to the UAV 5 caused by the collision, and further improving the safety and stability of the UAV 5 flying in complex environments. In addition, the buffer pads 8 can also reduce the damage to the colliding objects, thereby improving the practicality of the protective mechanism.

[0046] Furthermore, a connecting plate 1011 is integrally formed on the fixing seat 101, and the connecting plate 1011 is fixedly connected to the bottom of the fuselage of the drone 5 by a first bolt 1012; a first slot 102 is opened on the fixing seat 101, one end of the connecting arm 103 is inserted into the inside of the first slot 102, and the connecting arm 103 and the fixing seat 101 The plug-in part is fixedly connected by a second bolt 104, and the first bolt 1012 is used to facilitate disassembly and assembly of the fixing seat 101. By inserting one end of the connecting arm 103 into the inside of the first slot 102, the stability of the connection between the connecting arm 103 and the fixing seat 101 can be increased, and the second bolt 104 is used to facilitate disassembly and assembly of the connecting arm 103 and the fixing seat 101.

[0047] Furthermore, a connecting column 202 is fixedly installed at the bottom of the first protective frame 201, and the bottom of the connecting column 202 is fixedly connected to the end of the connecting arm 103 through a third bolt 105; a connecting rod 302 is fixedly installed at the bottom of the second protective frame 301, and an insert block 303 is integrally formed at one end of the connecting rod 302, and a second slot 203 is opened at the top of the first protective frame 201, and the insert block 303 is inserted into the inside of the second slot 203, and the insert block 303 and the first protective frame 201 are connected at the insertion position through the fourth The connection is fixed by bolts 204, and the third bolts 105 are used to connect and fix the first protective frame 201 and the connecting column 202, which is convenient for disassembly and assembly. By setting a second slot 203 on the first protective frame 201, the stability of the connection between the first protective frame 201 and the second protective frame 301 can be increased. The plug block 303 is a rectangular structure to avoid rotation. The first protective frame 201 and the second protective frame 301 are connected by the fourth bolts 204, which is convenient for disassembly and assembly of the first protective frame 201 and the second protective frame 301.

[0048] Furthermore, the second protective frame 301 has a conical structure that is narrow at the top and wide at the bottom. The second protective frame 301 with a conical structure helps to reduce air resistance during flight, allowing the drone to pass through the air more smoothly during flight, reducing energy consumption, and improving flight efficiency and endurance. At the same time, when debris falls on the second protective frame 301, the conical structure design can make the debris fall quickly from the second protective frame 301, further increasing the protective performance of the second protective frame 301.

[0049] Furthermore, the third protective frame 401 is in an arch bridge structure. While the third protective frame 401 with an arch bridge structure provides top protection for the fuselage, it also has a favorable guiding effect on the airflow around the fuselage, so that the airflow can flow through the fuselage more smoothly, reducing the airflow disturbance caused by the protective structure, further optimizing the aerodynamic performance of the UAV 5, and ensuring the stability and maneuverability of the UAV 5 at different flight speeds and postures. In addition, the design of the arch bridge structure can make debris quickly fall from the third protective frame 401, further increasing the protection performance of the third protective frame 401.

[0050] Furthermore, a shock-absorbing pad 106 is provided between the fixing seat 101 and the drone 5. The shock-absorbing pad 106 can effectively reduce the wear and looseness between the protective mechanism and the drone body caused by flight vibration or collision, improve the stability and reliability of the connection, and also play a certain shock-absorbing and protective role for the precision sensors and electronic components inside the drone 5, avoiding the impact of long-term vibration on their performance and service life.

[0051] Furthermore, the first protective frame 201, the second protective frame 301 and the third protective frame 401 are all made of aluminum alloy structures, and the surface of the frame is coated with a nano-ceramic coating. By adopting an aluminum alloy structure, the first protective frame 201, the second protective frame 301 and the third protective frame 401 have the characteristics of light weight and high strength. While ensuring the protection performance, the load of the drone 5 will not be excessively increased, which is beneficial to maintaining the flight performance of the drone 5. In addition, by coating the surface of the frame with a nano-ceramic coating, the nano-ceramic coating has excellent properties such as waterproof, dustproof and corrosion-resistant, and can resist the erosion of the protective frame and the body of the drone 5 by chemical substances, ensuring that the drone 5 can operate normally in harsh natural environments and special industrial environments, and expanding the application scenarios and scope of the drone 5.

[0052] The working principle of the present invention is:

[0053] The mounting component 1 serves as a basic connection structure, and firmly mounts the entire protection mechanism on the bottom of the UAV 5 fuselage, providing a stable support point for other protection components. The first protection frame 201 of the wing side protection component 2 surrounds the periphery of the UAV 5 wing, and can first block and buffer any collision threats from the side, bottom or top of the wing within a certain angle. The second protection frame 301 of the wing upper protection component 3 provides additional protection above the wing to prevent falling objects from directly impacting the top of the wing. The third protection frame 401 of the fuselage protection component 4 covers the upper part of the fuselage to prevent the fuselage from being hit by falling objects from above or colliding with obstacles above in special flight postures. The protection frames cooperate with each other to form a three-dimensional protection space, which physically protects the UAV 5 from possible collision damage from the outside world.

[0054] During the flight of the drone 5, the temperature sensor 107, the humidity sensor 108, the smoke sensor 109 and the impact sensor 205 monitor different environmental parameters and physical states respectively. The temperature sensor 107 and the humidity sensor 108 can monitor the temperature and humidity changes of the environment around the drone 5 in real time. When the ambient temperature and humidity exceed the normal working range of the drone 5, the wireless communication module transmits the data to the flight control system of the drone. The flight control system can adjust the flight mission or issue an alarm to the operator so that corresponding measures can be taken in time to ensure the safe operation of the drone 5. The smoke sensor 109 can play an important role in special application scenarios such as fire monitoring. Once the surrounding temperature and humidity are detected, When smoke is generated in the environment, the smoke sensor 109 immediately feeds back the signal to the flight control system through the wireless communication module, so that the UAV 5 can react quickly. The collision sensors 205 are distributed on the first protection frame 201, the second protection frame 301 and the third protection frame 401, which can accurately sense whether the UAV 5 has collided with each other during the flight, as well as the intensity and location information of the collision. The flight control system can quickly determine the damage of the UAV 5 based on the data sent by the collision sensor 205, and take corresponding emergency measures, such as adjusting the flight attitude, reducing the flight speed, starting the automatic return program, etc., to minimize the damage caused by the collision accident to the UAV and the potential risk to the surrounding environment;

[0055] By connecting the first protective frame 201, the second protective frame 301 and the third protective frame 401 into a whole: after being connected into a whole, the appearance of the entire protective mechanism is more coherent and smooth. During the flight of the drone 5, the air can flow through the protective structure more smoothly. The conical structure of the second protective frame 301 and the arch bridge structure of the third protective frame 401 can better guide the airflow, and work together with the first protective frame 201 to reduce the turbulence and separation of the airflow.
