Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) equipment technology, specifically to a fast-charging protective airbag for UAVs. Background Technology

[0002] Currently, drones, as a modern high-tech device, have been widely used in logistics, aerial photography, agricultural plant protection, and disaster monitoring in recent years. However, with the continuous expansion of drone application scenarios, their safety and reliability in complex environments have become increasingly prominent. Especially during takeoff and landing or in the event of a sudden crash, drones are prone to damage due to collisions or impacts, potentially leading to safety accidents. To address this issue, existing technologies typically employ protective frames or cushioning materials to protect drones. However, these traditional protection methods suffer from problems such as large size, heavy weight, and inconvenient installation, making it difficult to meet the demands for lightweight and efficient drone operations.

[0003] Furthermore, some drones have begun to incorporate airbag protection devices to cope with impacts in sudden situations. However, existing airbag protection devices generally suffer from slow inflation speed and untimely response, failing to deploy quickly during high-speed descents or emergency obstacle avoidance, thus failing to provide effective protection. At the same time, the installation and removal process of existing airbag devices is complex, and maintenance costs are high, limiting their widespread adoption in practical applications. Therefore, designing a drone protective airbag device that can inflate quickly, is easy to install, and has high reliability has become an urgent technical challenge to be solved.

[0004] To address the aforementioned issues, this invention aims to provide a fast-charging protective airbag for drones through innovative design and technical means. This airbag can rapidly deploy when a drone encounters an emergency, effectively absorbing impact energy, while also enabling easy installation and disassembly, thereby significantly improving the safety and practicality of drones. Utility Model Content

[0005] This utility model addresses the problems of complex structure, inconvenient installation, and insufficient protective performance of existing drone protection devices. Therefore, this utility model adopts the following technical solution:

[0006] This utility model provides a fast-charging protective airbag for unmanned aerial vehicles (UAVs), including a base, a fuselage, an airbag system, a locking and unlocking mechanism, and a ranging radar system. The base serves as the bottom support structure of the UAV, on which the fuselage is fixedly connected. The fuselage forms the core frame of the UAV, supporting the power system, control system, and other key components. Wings are fixed to the four corners of the fuselage with screws, providing flight propulsion. A built-in controller connects to the air pump of the airbag system and the ranging radar system via circuitry, enabling overall control of the UAV's operation.

[0007] Furthermore, the airbag system comprises an airbag, a hose, an air pump, and a mounting bracket. The airbag is positioned on the outer periphery of the mounting bracket and connected to the air pump via the hose. The air pump is fixedly mounted on the fuselage and electrically connected to the controller. When the controller receives a signal from the ranging radar system and determines that the drone faces a collision or crash risk, the controller sends a command to the air pump, driving it to deliver gas through the hose into the airbag, allowing the airbag to inflate quickly and form a protective barrier to prevent damage to the drone. The mounting bracket is detachably fixed to the base, facilitating maintenance and replacement of the airbag system.

[0008] Specifically, the locking and unlocking mechanism includes components such as a locking block, a locking groove, an insert block, a slot, a locking rod, and a spring assembly to ensure a stable connection between the mounting bracket and the base. One end of the mounting bracket has symmetrically arranged fixing plates with locking grooves. A corresponding groove is provided on the base, within which a locking block is slidably connected. The bottom of the locking block is inclined for easy insertion and locking, and a second spring connects the locking block to the groove, improving locking reliability. The other end of the mounting bracket has an integrally formed insert block that fits into a slot at the end of the base. A retaining plate is slidably connected inside the slot, and a first spring connects the retaining plate to the top wall of the slot, ensuring a tight fixation after insertion. Furthermore, side blocks are fixed to both sides of the base with screws. Each side block has an inner groove, within which a locking rod is slidably connected. A third spring connects the locking rod to the side wall of the inner groove. Locking holes matching the locking rod are provided on both sides of the insert block. Insertion of the locking rod into the locking hole achieves secondary locking, further enhancing connection stability.

[0009] Furthermore, the ranging radar system is symmetrically arranged at the bottom of the base and electrically connected to the controller for real-time monitoring of the distance information between the UAV and its surrounding environment. The ranging radar acquires distance data by transmitting and receiving signals and transmits the data to the controller. The controller analyzes the data according to a preset algorithm and determines whether the airbag system needs to be activated to provide protection.

[0010] The key components and their functions of this utility model are as follows:

[0011] Airbags: As a core protective component, airbags rapidly inflate upon collision or crash, forming a buffer barrier to reduce impact damage to the drone. The airbags are made of high-strength thermoplastic polyurethane elastomer (TPU) to ensure excellent tear resistance and abrasion resistance, while also meeting the requirement for rapid inflation.

[0012] Mounting bracket: Supports the airbag and allows for a detachable connection to the base, facilitating maintenance and replacement. The mounting bracket is made of lightweight aluminum alloy with an anodized surface, providing high strength and corrosion resistance.

[0013] Locking and unlocking mechanism: Through the cooperation of the locking block and slot, the insert block and slot, and the locking rod and lock hole, a stable connection between the mounting bracket and the base is ensured, while facilitating quick disassembly. The design of the locking and unlocking mechanism makes full use of the elastic characteristics of the spring assembly, so that the locking block, locking rod and other components can automatically reset after being subjected to force, thereby achieving reliable locking and convenient unlocking operations.

[0014] Ranging radar: Real-time monitoring of the distance between the drone and its surroundings provides accurate data support, enhancing the drone's safety and stability. The ranging radar operates in the frequency range of 24GHz to 77GHz, with a detection range of up to 10 meters and an accuracy of ±5 millimeters. It maintains high sensitivity and a low false alarm rate even in complex environments.

[0015] The technical effects of this utility model are specifically achieved through the following means:

[0016] S1. When the drone approaches an obstacle or enters a crash state during flight, the ranging radar system detects that the distance between the drone and the obstacle or the ground is less than a preset threshold, and then generates a trigger signal and transmits the signal to the controller.

[0017] S2. After receiving the trigger signal, the controller immediately sends a start command to the air pump. The air pump starts working and delivers compressed air to the inside of the airbag through the hose, so that the airbag completes the inflation action within 0.2 seconds and forms a protective barrier.

[0018] S3. After the airbag is inflated, its outer surface contacts the obstacle or the ground and absorbs the impact energy through deformation, thereby effectively reducing the impact force on the drone and avoiding damage to the aircraft.

[0019] S4. When the drone resumes normal flight or completes landing, the controller stops sending commands to the air pump, the air pump stops working, and the gas in the airbag is slowly discharged through the exhaust valve, restoring the initial state.

[0020] Furthermore, this invention significantly improves the protective performance of the drone by optimizing the structural design of the airbag system. The airbag system adopts a modular design, and the mounting bracket can be quickly disassembled and assembled with the base through structures such as clips, slots, inserts, and slots, allowing users to complete maintenance operations without the need for professional tools. In addition, the locking and unlocking mechanism adopts a multi-level locking design, using a dual locking mechanism of clips and slots, and locking rods and locking holes, combined with the elastic characteristics of the spring assembly, to ensure a firm and reliable connection between the mounting bracket and the base, while simplifying the unlocking process.

[0021] In particular, the integration of the ranging radar system and the controller enables intelligent operation of the drone. The ranging radar detects the distance between the drone and its surroundings using high-frequency electromagnetic waves. After transmitting the data to the controller, the controller analyzes the data using a preset algorithm to determine whether the drone is at risk of collision or crash, and activates the airbag system if necessary. This design not only improves the safety of the drone but also enhances its ability to adapt to complex environments.

[0022] In summary, this utility model solves the problems existing in current UAV protection devices by introducing a high-efficiency rapid-inflation airbag system, a stable and reliable locking and unlocking mechanism, and an intelligent ranging radar system. It significantly improves the protection performance, ease of operation, and intelligence level of UAVs, and has broad application prospects and market value.

[0033] This utility model provides a fast-charging protective airbag for drones, and its specific implementation is described in detail with reference to the accompanying drawings. Figures 1 to 6 As shown, the device includes a base 1, a body 2, an airbag system, a locking and unlocking mechanism, and a ranging radar system 23. Each component is precisely designed to achieve rapid response and efficient protection.

[0034] The base 1 serves as the bottom support structure for the UAV, on which the fuselage 2 is fixedly connected. The fuselage 2 forms the core frame, supporting the power system, control system, and other key components. Wings 3 are screwed to the four corners of the fuselage 2, providing flight propulsion. A controller 4 is built into the fuselage, electrically connected to the air pump 5 of the airbag system and the ranging radar system 23 via circuitry, enabling overall control of the UAV's operation. The ranging radar system 23 is symmetrically arranged at the bottom of the base 1, operating in a frequency range of 24GHz to 77GHz, with a detection range of up to 10 meters and an accuracy of ±5 millimeters. It maintains high sensitivity and a low false alarm rate in complex environments, monitoring the distance between the UAV and its surroundings in real time and transmitting the data to the controller 4.

[0035] The airbag system consists of an airbag 8, a hose 6, an air pump 5, and a mounting bracket 7. The airbag 8 is positioned on the outer periphery of the mounting bracket 7 and connected to the air pump 5 via the hose 6. The air pump 5 is fixedly mounted on the fuselage 2 and electrically connected to the controller 4. When the controller 4 receives a signal from the ranging radar system 23 and determines that the drone faces a collision or crash risk, it sends a command to the air pump 5, driving it to deliver gas through the hose 6 into the airbag 8, allowing the airbag 8 to inflate within 0.2 seconds, forming a protective barrier to prevent damage to the drone. The airbag 8 is made of high-strength thermoplastic polyurethane elastomer (TPU), possessing excellent tear resistance and abrasion resistance, while also meeting the requirements for rapid inflation. The mounting bracket 7 is detachably fixed to the base 1, facilitating maintenance and replacement of the airbag system. The mounting bracket 7 is made of lightweight aluminum alloy with an anodized surface, exhibiting high strength and corrosion resistance.

[0036] The locking and unlocking mechanism includes components such as a locking block 9, a locking groove 10, an insert block 15, a slot 12, a locking rod 17, and a spring assembly, which are used to ensure a stable connection between the mounting bracket 7 and the base 1. One end of the mounting bracket 7 has symmetrically arranged fixing plates 11, with locking grooves 10 formed on the fixing plates 11. The base 1 has a corresponding groove 18, within which a locking block 9 is slidably connected. The bottom of the locking block 9 is inclined for easy insertion and locking, and the locking block 9 is connected to the groove 18 by a second spring 19 to improve locking reliability. The other end of the mounting bracket 7 has an integrally formed insert block 15, which is adapted to the slot 12 at the end of the base 1. A retaining plate 14 is slidably connected inside the slot 12, and the retaining plate 14 is connected to the top wall of the slot 12 by a first spring 13 to ensure that the insert block 15 is tightly fixed after insertion. Side blocks 16 are fixed to both sides of the base 1 with screws. An inner groove 20 is formed inside the side block 16, and a locking rod 17 is slidably connected within the inner groove 20. The locking rod 17 is connected to the side wall of the inner groove 20 by a third spring 21. Locking holes 22, adapted to the locking rod 17, are formed on both sides of the insertion block 15. Inserting the locking rod 17 into the locking hole 22 achieves secondary locking, further enhancing connection stability. The design of the locking and unlocking mechanism fully utilizes the elastic characteristics of the spring assembly, allowing components such as the locking block 9 and the locking rod 17 to automatically reset after being subjected to force, thereby achieving reliable locking and convenient unlocking operations.

[0037] S1 When the drone approaches an obstacle or enters a crash state during flight, the ranging radar system 23 detects that the distance between the drone and the obstacle or ground is less than a preset threshold, and then generates a trigger signal and transmits the signal to the controller 4. S2 After receiving the trigger signal, the controller 4 immediately sends a start command to the air pump 5. The air pump 5 starts working and delivers compressed air to the airbag 8 through the hose 6, so that the airbag 8 completes the inflation action within 0.2 seconds, forming a protective barrier. S3 After the airbag 8 is inflated, its outer surface contacts the obstacle or ground, and absorbs the impact energy through deformation, thereby effectively reducing the impact force on the drone and preventing damage to the body 2. S4 When the drone returns to normal flight or completes landing, the controller 4 stops sending commands to the air pump 5, the air pump 5 stops working, and the gas in the airbag 8 is slowly discharged through the exhaust valve, returning to the initial state.

[0038] This invention significantly improves the protective performance of drones by optimizing the structural design of the airbag system. The airbag system adopts a modular design; the mounting bracket 7 can be quickly disassembled and assembled with the base 1 via structures such as the locking block 9, locking slot 10, insert block 15, and slot 12, allowing users to complete maintenance operations without the need for specialized tools. Furthermore, the locking and unlocking mechanism employs a multi-level locking design. Through a dual locking mechanism of the locking block 9 and locking slot 10, and the locking rod 17 and locking hole 22, combined with the elastic characteristics of the spring assembly, the connection between the mounting bracket 7 and the base 1 is ensured to be firm and reliable, while simplifying the unlocking process.

[0039] Specifically, the integration of the ranging radar system 23 and the controller 4 enables intelligent operation of the UAV. The ranging radar detects the distance between the UAV and its surroundings using high-frequency electromagnetic waves. After transmitting the data to the controller 4, the controller 4 analyzes the data using a preset algorithm to determine whether the UAV faces a collision or crash risk, and activates the airbag system if necessary. This design not only improves the safety of the UAV but also enhances its ability to adapt to complex environments.

[0040] In practical applications, such as when a drone is performing a logistics delivery mission, sudden changes in wind or navigation system errors may cause it to deviate from its flight path, leading to a risk of crashing. In this situation, the ranging radar system 23 monitors the distance between the drone and the ground in real time and quickly generates a trigger signal when the distance is less than a safe threshold. The controller 4 activates the air pump 5 based on the signal, which injects compressed air into the airbag 8, causing it to inflate and deploy in a very short time, forming a buffer barrier. When the drone crashes into the ground, the airbag 8 absorbs the impact energy through deformation, effectively protecting the drone body 2 and its internal equipment from damage. After the mission is completed, the airbag 8 slowly deflates through the exhaust valve, returning to its initial state for subsequent use.

[0041] In summary, this utility model solves the problems existing in current UAV protection devices by introducing a high-efficiency rapid-inflation airbag system, a stable and reliable locking and unlocking mechanism, and an intelligent ranging radar system. It significantly improves the protection performance, ease of operation, and intelligence level of UAVs, and has broad application prospects and market value.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
