Description

Technical Field

[0001] This invention belongs to the field of unmanned aerial vehicle (UAV) technology, specifically a buffer airbag device for UAV landing that can be automatically deployed. Background Technology

[0002] Drones are short for unmanned aerial vehicles. They have advantages such as small size and ease of use. Currently, drones are widely used in many fields. Drones need a platform of a certain area to ensure their attitude and level when taking off and landing. Nowadays, drones are widely used in aerial photography and agriculture, and often need to carry out tasks in mountainous areas, fields or on the roof of vehicles.

[0003] However, the drone landing platform lacks a cushioning structure, which could cause damage to the drone during landing. Additionally, securing the drone to the top of the device after it has come to a stop can prevent it from falling when the vehicle is in motion or in harsh external conditions, even if it has not started. Summary of the Invention

[0004] The purpose of this invention is to provide an automatically deployable airbag device for drone landing in order to solve the problems mentioned above.

[0005] The technical solution adopted in this invention is as follows: A automatically deployable airbag device for drone landing includes a base, a buffer block, and a drone body. A fixed frame is fixedly installed on the upper surface of the base. A buffer block is installed above the base and the fixed frame. Airbag holes are provided on the four sides of the buffer block. Airbag blocks are installed inside the buffer block corresponding to the airbag holes. Two vertical plates are fixedly installed on one side of the base inside the fixed frame. A fixed guide rod is installed on the middle surface of the two vertical plates. Two movable sleeves are movably installed on the surface of the fixed guide rod. The surfaces of the movable sleeves and the fixed guide rod are... The movable sleeve is equipped with a spring and has a movable component movably mounted on its upper surface via a connecting rod. A connecting post is fixedly mounted on the middle surface of the movable component, and an airbag block is mounted on the top surface of the connecting post. By setting up the airbag block, spring, and guide rod assembly, a double buffer structure is constructed. The impact force after the UAV lands pushes the buffer block down, and the connecting rod drives the movable sleeve to slide along the fixed guide rod. The spring initially absorbs the impact energy. At the same time, the airbag block automatically deploys from the airbag hole to further buffer the impact force, solving the problem of damage to UAVs caused by the lack of buffer in traditional landing platforms and significantly reducing the risk of collision damage during UAV landing.

[0006] In a preferred embodiment, four fixed seats are fixedly installed at the upper surface edge of the buffer block. A micro drive motor is installed on one side of the interior of each fixed seat. A rotating rod is installed at the output end of the micro drive motor. A rotating sleeve is movably installed on the surface of the rotating rod, and a limit frame is fixedly installed on the surface of the rotating sleeve. The micro drive motor drives the rotating rod to rotate, causing the rotating sleeve and the limit frame to flip. This can limit and fix the drone body around its perimeter after landing, preventing the drone from shifting or falling in harsh environments such as when vehicles are moving or in strong winds. The symmetrical layout of the four limit frames ensures the stability of the fixation and prevents the drone from detaching from the landing platform due to external interference when it is not started.

[0007] In a preferred embodiment, a charging docking block is provided in the middle of the upper surface of the buffer block, and the charging docking block is electrically connected to the power source inside the fixed frame. After the drone lands, its bottom charging interface can automatically dock with the charging docking block, and charging can be achieved without manual intervention, solving the cumbersome problem of traditional drones requiring manual disassembly and charging. The power source built into the fixed frame provides continuous power for charging, ensuring that the drone automatically replenishes its power during work breaks, improving work efficiency and adapting to long-term outdoor work scenarios.

[0008] In a preferred embodiment, a fluorescent ring is provided on the upper surface of the buffer block, and the drone body is placed on the surface of the buffer block. The fluorescent ring can emit fluorescence in dim environments, providing a clear landing positioning mark for the drone, helping the drone to accurately identify the landing area and avoid landing deviations caused by poor visibility. At the same time, the fluorescent ring can help operators quickly find the landing platform, improving the ease of use in complex environments.

[0009] In a preferred embodiment, a signal pole is provided on the upper surface of the drone body, and a camera is provided on the bottom surface of the drone body. The signal pole enhances the signal transmission strength between the drone and the remote controller or base station, reduces signal interference in complex environments such as mountainous areas and tall buildings, and ensures the stability of the drone's flight and landing control. The camera can capture images of the landing area in real time, assisting operators in judging the status of the landing platform, while also taking into account the image acquisition needs of the operation scene, thus improving the functionality of the device.

[0010] In a preferred embodiment, four connecting rods are fixedly provided on the bottom surface of the drone body, and a curved frame is fixedly provided on the bottom surface of the connecting rods on the same side. The curved frame is correspondingly provided with a limiting frame. The corresponding design of the curved frame and the limiting frame allows the limiting frame to precisely engage with the curved frame when it is flipped, forming a fixed fit between the limiting frame and the curved frame, preventing the drone from shaking during the fixing process. The symmetrical layout of the four connecting rods ensures that the bottom of the drone is evenly stressed, and the arc structure of the curved frame can disperse the local impact force during landing, further protecting the drone body.

[0011] In a preferred embodiment, four mounting blocks are fixedly mounted on both sides of the main body of the UAV. A wing rod is movably mounted on the middle surface of the mounting blocks. One end of the wing rod is movably mounted with a wing fan via a rotating rod. Four micro wing motors of the same frequency and model are mounted on the upper surface of the four mounting blocks. The four micro wing motors synchronously drive the wing fan to rotate, ensuring the stability of the UAV's flight attitude. The movable connection design between the wing rod and the rotating rod allows for fine adjustment of the wing angle during UAV landing, assisting the UAV in accurately aligning with the landing platform. The fixed structure of the mounting blocks ensures a firm connection of the wing assembly, preventing the wing from detaching during flight or landing and improving the flight safety of the UAV.

[0012] In a preferred embodiment, a groove is formed on the top surface of the drone body, and a fixing block and a clamping block are correspondingly provided in the groove. The clamping blocks are movably provided at both ends of the fixing block through guide rods and springs. The clamping blocks can slide along the guide rods under the elastic force of springs, thereby clamping and fixing the signal rod or other auxiliary components, avoiding signal instability or structural damage caused by component shaking during drone flight. The guide rods ensure the stability of the sliding trajectory of the clamping blocks, and the elastic force of springs can adapt to components of different diameters, improving the adaptability of the device to drone auxiliary components.

[0013] In a preferred embodiment, an angle connecting frame is fixedly mounted on the upper surface of the fixing block, and a signal rod is mounted on the upper surface of the angle connecting frame. A counterweight is mounted on one end of the signal rod inside the angle connecting frame. The angle connecting frame can adjust the installation angle of the signal rod to ensure that the signal rod always faces the signal source, thereby improving signal reception efficiency. The counterweight balances the center of gravity of the signal rod, preventing flight attitude imbalance caused by the shift of the signal rod's center of gravity during drone flight. It also prevents the signal rod from shifting its angle due to vibration or airflow, ensuring signal transmission stability.

[0014] In a preferred embodiment, the surfaces of the base and the buffer block are coated with a waterproof layer, and the surface of the buffer block is provided with anti-slip texture. The waterproof layer can prevent rainwater and dew from penetrating into the device, avoid corrosion of the base, buffer block and internal components such as springs and motors, extend the service life of the device, and adapt to outdoor humid environments. The anti-slip texture on the surface of the buffer block increases the friction with the bottom of the drone body, preventing the drone from sliding after landing due to the smooth surface, and further improving landing stability.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. By setting up an airbag block, spring and guide rod assembly to build a dual buffer structure, the impact force after the drone lands pushes the buffer block down, the connecting diagonal rod drives the movable sleeve to slide along the fixed guide rod, and the spring initially absorbs the impact energy; at the same time, the airbag block automatically unfolds from the airbag hole to further buffer the impact force, solves the problem of drone damage caused by the lack of buffer in traditional landing platforms, and greatly reduces the risk of collision damage when the drone lands.

[0016] 2. The micro drive motor drives the rotating rod to rotate, causing the rotating sleeve and the limiting frame to flip. This can limit and fix the drone body around its perimeter after landing, preventing the drone from shifting or falling in harsh environments such as when vehicles are moving or in strong winds. The symmetrical layout of the four limiting frames ensures the stability of the fixation and prevents the drone from detaching from the landing platform due to external interference when it is not started.

The micro drive motor 17 drives the rotating rod 18 to rotate, causing the rotating sleeve 19 and the limit frame 16 to flip. This can limit and fix the drone body 4 around after landing, preventing the drone from shifting or falling in harsh environments such as vehicle driving or strong winds. The symmetrical layout of the four limit frames 16 ensures the stability of the fixation and prevents the drone from leaving the landing platform due to external interference when it is not started.

[0022] Reference Figure 1-3A charging docking block 20 is provided in the middle of the upper surface of the buffer block 3, and the charging docking block 20 is electrically connected to the power supply inside the fixed frame 2. After the drone lands, its bottom charging interface can automatically dock with the charging docking block 20, and charging can be achieved without manual intervention, solving the cumbersome problem of traditional drones needing to be manually disassembled for charging.

The fluorescent ring 6 can emit fluorescence in dim environments, providing clear landing positioning marks for the drone, helping the drone to accurately identify the landing area and avoid landing deviations caused by poor visibility; at the same time, the fluorescent ring 6 can help operators quickly find the landing platform, improving the ease of use in complex environments.

[0024] Reference Figure 1-4 The upper surface of the drone body 4 is equipped with a signal pole 21, and the bottom surface of the drone body 4 is equipped with a camera 24. The signal pole 21 enhances the signal transmission strength between the drone and the remote controller or base station, reduces signal interference in complex environments such as mountainous areas and tall buildings, and ensures the stability of the drone's flight and landing control. The camera 24 can capture images of the landing area in real time, assisting operators in judging the status of the landing platform, while also taking into account the image acquisition needs of the operation scene, thus improving the functionality of the device.

[0025] Reference Figure 1-4 Four connecting rods 22 are fixedly installed on the bottom surface of the drone body 4, and a curved frame 23 is fixedly installed on the bottom surface of the connecting rod 22 on the same side. The curved frame 23 is correspondingly installed with the limiting frame 16. The corresponding design of the curved frame 23 and the limiting frame 16 allows the limiting frame 16 to precisely engage with the curved frame 23 when it is flipped, forming a fixed fit between the limiting frame and the curved frame, preventing the drone from shaking during the fixing process. The symmetrical layout of the four connecting rods 22 ensures that the bottom of the drone is evenly stressed, and the arc structure of the curved frame 23 can disperse the local impact force during landing, further protecting the drone body.

[0026] Reference Figure 1-5Four mounting blocks 28 are fixedly installed on both sides of the main body 4 of the drone. A wing rod 26 is movably installed on the middle surface of the mounting blocks 28. One end of the wing rod 26 is movably connected to a wing fan 25 via a rotating rod 29. Four micro wing motors 27 of the same frequency and model are installed on the upper surface of the four mounting blocks 28. The four micro wing motors 27 synchronously drive the wing fan 25 to rotate, ensuring the stability of the drone's flight attitude. The movable connection design between the wing rod 26 and the rotating rod 29 allows for fine adjustment of the wing angle during drone landing, assisting the drone in accurately aligning with the landing platform. The fixed structure of the mounting blocks 28 ensures that the wing components are firmly connected, preventing the wing from falling off during flight or landing, and improving the drone's flight safety.

[0027] Reference Figure 1-6 The top surface of the drone body 4 has a groove, and a fixing block 30 and a clamping block 31 are correspondingly provided in the groove. The clamping blocks 31 are movably provided at both ends of the fixing block 30 through the guide rod 32 and the second spring 35. The clamping blocks 31 can slide along the guide rod 32 under the elastic force of the second spring 35, so as to clamp and fix the signal rod 21 or other auxiliary components, and avoid signal instability or structural damage caused by component shaking during drone flight. The guide rod 32 ensures the stability of the sliding trajectory of the clamping blocks 31, and the elastic force of the second spring 35 can be adapted to components of different diameters, improving the adaptability of the device to drone auxiliary components.

A signal rod 21 is installed on the upper surface of the angle connecting frame 33. A counterweight block 34 is installed at one end of the signal rod 21 inside the angle connecting frame 33. The angle connecting frame 33 can adjust the installation angle of the signal rod 21 to ensure that the signal rod 21 always faces the signal source and improves the signal reception efficiency. The counterweight block 34 balances the center of gravity of the signal rod 21 to avoid flight attitude imbalance caused by the center of gravity of the signal rod 21 shifting during the flight of the UAV. At the same time, it prevents the signal rod 21 from shifting its angle due to vibration or airflow, thus ensuring the stability of signal transmission.
