The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0061] In recent years, with the rapid development of drone technology, its application in fields such as power inspection, logistics distribution, emergency communications, and environmental monitoring has become increasingly widespread. However, in practical applications, drones still face problems such as limited flight endurance, restricted takeoff and landing areas, and insufficient mission expansion capabilities.

[0062] First, drone helipads, as crucial infrastructure for drone systems, play a key role in providing core functions such as takeoff and landing, parking, maintenance, and mission expansion. Their design and functionality have been gradually refined with technological advancements, and they are showing a trend of diversification in practical applications. Early drone helipads were primarily simple takeoff and landing platforms, barely meeting the basic landing needs of drones. However, with the increasing diversity of drone application scenarios (such as power inspection, logistics distribution, and emergency communications), helipad designs have gradually evolved towards multifunctionality and intelligence. For example, modern helipads not only support precise landing and automatic homing for drones, but also integrate multiple functions such as wireless charging, status monitoring, and mission scheduling, significantly improving the efficiency and reliability of drone operations. Furthermore, some helipads incorporate environmentally friendly designs (such as windproof, rainproof, and corrosion-resistant materials) and energy management technologies (such as solar power supply), enabling long-term and stable operation in complex environments. Currently, drone helipads are primarily categorized into two types: fixed and portable.

[0063] (1) Fixed helipads: These helipads are usually deployed on the ground or on top of buildings and are suitable for long-term use.

[0064] (2) Portable helipad: In order to meet the needs of temporary missions, some studies have proposed foldable or lightweight UAV helipad devices.

[0065] Although existing drone landing pads have made some progress in structural design and functional integration, such as improving landing accuracy and automation through the introduction of mechanical guidance mechanisms, electromagnetic adsorption devices, and intelligent visual recognition systems, they still face many technical bottlenecks in practical applications, especially in terms of adaptability in complex scenarios, functional expansion capabilities, and environmental tolerance. These are specifically reflected in the following aspects:

[0066] (1) Insufficient adaptability: The design of existing drone landing pads is mostly based on flat ground or ideal environment, which makes it difficult to meet the needs of complex terrain or special scenarios. For example, in tasks such as high-voltage transmission line inspection and remote mountain monitoring, drones often need to rely on towers, slopes or other platforms to complete takeoff and landing. However, most of the current landing pads lack the ability to adapt to these special scenarios. The mechanical structure cannot cope with irregular terrain, and the deployment flexibility is low, which greatly limits their practical application. In addition, although some portable landing pads have a certain degree of mobility, they are prone to displacement or overturning in complex environments (such as strong winds and steep slopes), which further weakens their applicability.

[0067] (2) Single function: Most current drone landing pads only have basic take-off and landing and charging functions, and lack support for diverse mission requirements. For example, in emergency communication scenarios, drones are often used as temporary relay nodes, but existing landing pads cannot provide signal enhancement or data backhaul support for drones. This single function not only limits the application scope of drones, but also leads to low resource utilization of landing pads, making it difficult to fully realize their potential as infrastructure.

[0068] (3) Poor environmental adaptability: Under adverse weather conditions (such as strong winds, rain, snow, high temperatures, etc.), the stability and reliability of existing drone landing pads still need to be improved. For example, some landing pads adopt an open structure design, which is prone to mechanical component failure due to water accumulation, snow accumulation or ice formation in rainy and snowy weather; and the contact charging interface has a short circuit risk in a humid environment, requiring additional protective measures. In addition, strong wind environments place higher demands on the structural strength of the landing pad, but existing designs often lack sufficient wind resistance, and are easily affected by vibration or impact and affect the precise landing of drones. These problems not only reduce the availability of the landing pad, but also increase maintenance costs and failure rates.

[0069] Second, the endurance of drones is a key factor affecting their operational efficiency, directly determining flight duration, coverage, and mission completion quality. However, due to bottlenecks in battery technology, current drones generally have short flight times, especially under high loads or in complex environments. Therefore, how to efficiently and quickly recharge drones has become a core link in improving operational efficiency, and charging technology has therefore become a research hotspot. In actual applications, frequent drone returns for charging increase costs and may cause mission interruptions. For example, low charging efficiency in logistics and distribution will reduce delivery speed, and running out of power in emergency rescue may directly affect the rescue effect. At the same time, with the diversification of application scenarios, charging technology is developing in multiple directions: wireless dynamic charging is explored in urban environments, while remote areas focus on portability, environmental adaptability, and the ability to coordinate charging of multiple devices. Despite this, existing technologies still face problems such as the contradiction between efficiency and distance, and insufficient environmental compatibility, and urgently need innovative breakthroughs to improve endurance and operational efficiency. Currently, drone charging methods mainly include contact charging and wireless charging:

[0070] 1) Contact charging: This technology transfers energy through direct contact between the drone's landing gear and electrodes on the landing pad. Its core principle is to leverage the physical connection between conductive materials to achieve efficient electrical energy transfer. For example, some designs employ mechanical clamping mechanisms or guides to ensure precise alignment between the landing gear and the charging electrodes during landing. This solution offers advantages such as a simple structure, mature technology, high charging efficiency, and low manufacturing and maintenance costs. It is therefore well-suited for large-scale deployment in scenarios such as logistics and power inspections.

[0071] 2) Wireless Charging: Based on the principles of electromagnetic induction or magnetic resonance, wireless charging achieves efficient energy transmission through a contactless method. In recent years, with the advancement of magnetic coupling technology, wireless charging has gradually become an important research direction in the field of drone charging. For example, some studies have proposed adaptive charging methods based on coil coupling feedback, which can dynamically adjust the charging power according to the battery status and position of the drone, thereby improving energy transmission efficiency and reducing losses. The greatest advantage of wireless charging technology lies in its flexibility: charging can be completed without precise alignment, making it particularly suitable for unmanned operations in complex environments, such as high-voltage transmission line inspections or disaster relief scenarios.

[0072] The advantages of existing charging technologies are obvious, such as the high efficiency and low cost of contact charging, and the flexibility and environmental adaptability of wireless charging. These features have made them play an important role in drone applications. However, with the diversification and complexity of drone application scenarios, existing charging technologies have also exposed some problems that need to be solved urgently. These problems not only limit the large-scale application of drones, but also point the way for future technological innovation:

[0073] (1) Insufficient support capacity for multiple drones: Current charging technologies are mostly focused on single drone charging scenarios and lack the ability to support simultaneous charging of multiple drones. This limitation is particularly prominent in scenarios that require large-scale drone collaboration. For example, in the field of logistics and distribution, when multiple drones return home after completing their delivery missions at the same time, the existing charging system often cannot meet their rapid energy replenishment needs, resulting in low mission efficiency. Similarly, in disaster relief scenarios, multiple drones may need to perform search and rescue, communication relay, or material delivery missions at the same time, and insufficient charging capacity will directly affect the overall rescue efficiency. In addition, charging multiple drones also involves complex issues such as energy allocation and priority scheduling. Existing technologies have not yet formed a complete solution in this regard, which has become an important bottleneck restricting the large-scale application of drones.

[0074] (2) Charging efficiency and distance limitations: Although wireless charging technology has attracted widespread attention for its flexibility and contactless operation, its transmission efficiency and effective distance are still significantly limited, especially in high-power charging scenarios. For example, wireless charging systems based on electromagnetic induction or magnetic resonance can usually only achieve efficient energy transmission within a few centimeters. Once the landing position of the drone deviates from the charging area, the charging efficiency may drop significantly or even fail completely. In addition, the energy loss problem of wireless charging is more prominent in high-power scenarios, making it difficult to meet the fast charging requirements of high-performance drones. At the same time, the wireless charging system is susceptible to external environmental interference (such as metal objects, electromagnetic noise, etc.), which further reduces its stability and reliability. These problems make wireless charging technology face many challenges in practical applications, especially in unmanned scenarios in complex environments, where its performance is often difficult to meet expectations.

[0075] Third, in scenarios where communication coverage is insufficient or interrupted (such as remote mountainous areas, disaster areas, offshore platforms, etc.), drones are often used as temporary communication relay nodes to provide solutions for restoring communications and expanding network coverage. For example, after a natural disaster, relevant communication facilities may be destroyed, resulting in the disaster area losing contact with the outside world. At this time, drones can be quickly deployed above the disaster-stricken area, equipped with 5G base stations, Wi-Fi hotspots or satellite communication modules to provide temporary signal coverage for ground users, ensuring rescue command and disaster assessment. In addition, drones also play an important role in remote areas or special missions. For example, in forest fire monitoring, drones can transmit fire data in real time and send it back to the command center; between offshore oil and gas platforms or ocean-going ships, drones act as communication bridges to solve the problem of long-distance communication. However, drone relay technology still faces problems such as insufficient endurance and weak anti-interference performance, and urgently needs further optimization. In the existing technology, some studies have attempted to combine signal relay functions with drone platforms:

[0076] (1) Fixed relay station: A fixed relay station is a solution that deploys relay equipment on specific infrastructure (such as drone hangars, communication base stations, or tower platforms). Taking the central air-conditioning system installed in a drone hangar as an example, this design significantly improves the operational stability and reliability of the relay equipment by optimizing heat dissipation performance. For example, in high temperature or high load environments, relay equipment is prone to performance degradation or even failure due to overheating, while an efficient heat dissipation system can effectively extend the working time of the equipment and ensure the quality of signal transmission. In addition, fixed relay stations are usually equipped with stable power supply and protective measures, and can operate for a long time in harsh environments. They are very suitable for scenarios that require continuous communication guarantee (such as power inspections, urban communication coverage, etc.).

[0077] (2) Mobile relay nodes: Mobile relay nodes rely on drones as carriers to achieve dynamic communication coverage in a flexible and maneuverable manner. For example, some studies have proposed drone hangars with a return function, which support drones to automatically return for supplies (such as charging, data uploading, etc.) after performing relay tasks, thereby greatly improving the system's continuous operation capability. The biggest advantage of this solution is its high flexibility: drones can quickly adjust their positions according to mission requirements, dynamically cover communication blind spots or expand network range. For example, in disaster relief scenarios, drone relay nodes can be quickly deployed over disaster areas to provide temporary signal coverage for ground users; in logistics distribution or monitoring tasks, drones can also simultaneously assume the dual responsibilities of relaying and mission execution, greatly improving resource utilization efficiency.

[0078] The main features of existing signal relay technology are:

[0079] (1) Endurance limitation: When performing relay missions, drones usually need to hover for a long time to ensure the continuity and stability of signal coverage. However, this high-energy-consuming working mode will cause the drone battery to be quickly depleted, and the endurance time will be greatly shortened. For example, when performing emergency communication missions, the drone may only be able to hover for a few hours before returning to recharge or replace the battery, which not only interrupts the mission process but also increases operation and maintenance costs. In addition, frequent take-off and landing and resupply operations will also have a negative impact on the overall mission efficiency.

[0080] (2) Weak anti-interference capability: In complex electromagnetic environments (such as near high-voltage transmission lines, urban buildings, or other interference areas), the signal transmission quality of drone relay nodes is easily interfered with, affecting communication effectiveness. For example, the strong electromagnetic field around high-voltage lines may cause signal attenuation or distortion, or even cause communication interruption. In addition, in an environment where multiple frequency bands coexist, drone relay equipment may conflict with other communication systems, further reducing the stability of signal transmission.

[0081] Fourth, poles and towers, as a common infrastructure, are widely used in the fields of electricity, communications, etc., and are an important support for the operation of modern society. In the power system, poles and towers are used to erect high-voltage transmission lines and undertake power transmission tasks, especially in complex terrains. They play an irreplaceable role. In the field of communications, poles and towers are used to install base station antennas and signal transmission equipment to provide coverage support for wireless networks. The application scenarios of poles and towers are constantly expanding. For example, in the construction of smart cities, some poles and towers have been transformed into multi-functional platforms that integrate functions such as lighting, monitoring, and environmental monitoring. At the same time, with the development of drone technology, poles and towers have gradually become ideal carriers for drone take-off and landing, charging, and mission expansion, especially in transmission line inspections and emergency communication guarantees. They have shown great potential. In recent years, some studies have attempted to combine drone technology with pole and tower facilities to improve operation and maintenance efficiency:

[0082] (1) Transmission line inspection: In the power system, transmission line inspection is an important task to ensure the safety of the power grid. The relevant methods are inefficient and costly, but the introduction of drones has significantly improved the inspection capabilities. For example, the push-rod lifting apron is specially designed for transmission towers and is used for drone take-off and landing and charging, making full use of the tower space resources. This design allows the drone to quickly return to the apron to charge or upload data after completing the inspection, significantly shortening the task interval, reducing manual intervention, and improving inspection efficiency. Some aprons also integrate wireless charging and status monitoring functions, which to a certain extent improve the level of intelligence.

[0083] (2) Communication base station expansion: In urban communication network coverage, drone landing pads based on streetlight poles are an innovative solution. Drones can be deployed on streetlight poles as temporary relay nodes to quickly expand signal coverage. Streetlight poles themselves have power supply and space advantages. After adding landing pads, drones can be used for takeoff and landing, charging, and task scheduling. They can also be combined with other smart city functions (such as environmental monitoring) to improve resource utilization.

[0084] The technical characteristics of existing tower application scenarios include:

[0085] (1) Single function: Existing tower facilities have relatively single functions. Most of them only support drone takeoff and landing or charging, and lack extended functions such as relay and monitoring. For example, in emergency communication or logistics distribution scenarios, the existing design cannot meet the needs of signal relay, video monitoring or multi-task collaboration, which limits the efficiency of the system.

[0086] (2) Low integration: Existing tower facilities fail to achieve an integrated design for docking, charging, and relay functions. For example, some aprons only provide take-off and landing platforms, and charging and relay equipment need to be installed separately, resulting in system redundancy and high deployment costs. Insufficient inter-module coordination affects overall efficiency.

[0087] (3) Insufficient intelligence: Existing systems rely heavily on manual intervention and lack automated task scheduling and status monitoring capabilities. For example, drone landing, charging, and task assignment often require manual operation, making it difficult to adapt to dynamic task requirements. Furthermore, the ability to monitor drone status in real time is weak, increasing the difficulty of operation and maintenance.

[0088] In summary, related drone applications have defects in docking, charging, relaying, etc.:

[0089] First, the technical defects of the drone landing pad include:

[0090] (1) Complex structure and high cost: The design of existing drone landing pads mostly relies on mechanical clamping mechanisms, guiding devices or high-precision sensors to achieve accurate centering and positioning of drones. For example, some high-end landing pads use complex electromagnetic adsorption devices or visual recognition systems to ensure that drones can accurately align when landing. However, this design leads to a high degree of complexity in the system structure, which not only increases manufacturing costs, but also significantly increases the difficulty of maintenance and the threshold for use. Especially in scenarios that require large-scale deployment (such as logistics distribution and power inspections), high costs have become an important factor restricting their popularization. In addition, in order to further improve landing accuracy, some designs also require additional visual recognition or laser ranging modules. These high-precision devices are not only expensive, but also have high hardware performance requirements, further increasing the overall deployment cost. Therefore, how to simplify the structure and reduce costs while ensuring functionality is an urgent problem that needs to be solved.

[0091] (2) Insufficient environmental adaptability: Currently, most drone landing pads are designed mainly for flat ground or ideal environments, and lack the ability to adapt to complex terrain and severe weather. For example, in platform scenarios such as mountains, slopes or towers, the mechanical structure of existing landing pads often cannot cope with irregular terrain, resulting in drones being unable to land safely or failing to charge. At the same time, the stability of the landing pad also faces severe challenges under severe weather conditions (such as strong winds, rain, snow, high temperatures, etc.). For example, strong winds may cause the landing pad to shift or overturn, and rainy and snowy weather can easily cause corrosion of mechanical components or electrical short circuits. In addition, although some portable landing pads have a certain degree of flexibility, they still show obvious fragility in extreme environments, making it difficult to ensure the safe docking of drones. These problems seriously limit the practical application of landing pads in diverse scenarios, especially in complex tasks such as power line inspections and disaster relief.

[0092] (3) Single function: The functional design of existing drone landing pads is generally relatively simple, usually only supporting two basic functions: take-off and landing and charging. With the increasing diversification of drone application scenarios, single-function landing pads can no longer meet the needs of complex missions.

[0093] Second, the defects of drone charging technology:

[0094] (1) Efficiency and compatibility issues:

[0095] Contact charging: Contact charging transfers energy through direct contact between the drone's landing gear and electrodes on the landing pad. Its core advantages lie in its high charging efficiency (typically exceeding 90%) and mature technology. However, this solution requires extremely high landing precision from the drone. In complex environments (such as strong winds, vibrations, or uneven surfaces), displacement or misalignment can easily lead to poor contact, significantly reducing charging efficiency. For example, in logistics and delivery scenarios, the frequent takeoffs and landings of drones can cause mechanical wear, further exacerbating the problem of poor contact. Furthermore, in rainy and snowy weather, contact charging interfaces are susceptible to moisture intrusion, posing a risk of short circuits and even damage to the device. These issues not only reduce system reliability but also increase maintenance costs and safety risks.

[0096] Wireless charging: Wireless charging is based on the principles of electromagnetic induction or magnetic resonance, and achieves energy transmission in a contactless manner. It has high flexibility and is particularly suitable for unmanned operations in complex environments. However, wireless charging technology still faces significant technical bottlenecks. First, its transmission efficiency is usually lower than that of contact charging, especially in high-power scenarios, where the energy loss problem is particularly prominent. Secondly, the effective transmission distance of wireless charging is short, and efficient energy transfer can usually only be achieved within a few centimeters. Once the landing position of the drone deviates from the charging area, charging may fail. In addition, the wireless charging system is susceptible to external electromagnetic interference, especially in complex electromagnetic environments such as near high-voltage lines or urban buildings, where signal stability is difficult to guarantee. These problems limit the application of wireless charging in high-performance drones and large-scale mission scenarios.

[0097] (2) Insufficient multi-device support:

[0098] Most existing charging systems are designed for a single drone and lack the ability to support the coordinated charging of multiple drones. This creates a clear shortcoming in scenarios that require large-scale drone collaboration. For example, in the field of logistics and distribution, when multiple drones complete their missions and return home at the same time, the existing single-device charging mode cannot meet the demand for rapid energy replenishment, resulting in longer mission intervals and affecting overall delivery efficiency. Similarly, in disaster relief scenarios, multiple drones may need to perform search and rescue, communication relay, or material delivery missions at the same time, and insufficient charging capacity will directly affect mission continuity. In addition, charging multiple drones also involves complex issues such as energy allocation and priority scheduling. Existing technologies have not yet formed a complete solution in this regard, further restricting the large-scale application of drones.

[0099] (3) Environmental dependence:

[0100] Related charging technologies are highly dependent on the external environment, and perform poorly in particularly adverse weather conditions. For example, in rainy and snowy weather, contact-type charging interfaces can easily short-circuit due to moisture intrusion, or even damage the device. While wireless charging systems do not require physical contact, changes in electromagnetic fields can also lead to decreased efficiency or unstable signals in humid environments. To address these issues, existing designs typically require additional protective measures (such as waterproof coatings, sealing structures, etc.), but this not only increases system complexity and cost, but also makes maintenance more difficult. In addition, battery performance itself can be affected in extremely high or low temperature environments, further exacerbating the environmental adaptability issues of the charging system. These issues significantly reduce the reliability of related charging technologies in outdoor or unattended scenarios.

[0101] Third, the limitations of drone relay functions:

[0102] (1) Limited endurance: When performing relay missions, drones usually need to hover in a specific area for a long time to maintain signal coverage. However, this working mode consumes a lot of battery, resulting in a significant reduction in the drone's endurance. For example, in emergency communication scenarios, drones may only be able to hover for a few hours before returning to recharge or replace batteries, which not only interrupts the mission process but also reduces the overall mission efficiency. In addition, frequent take-off and landing and resupply operations increase operation and maintenance costs and have a negative impact on mission continuity. Especially in remote areas or complex terrain, the lack of charging facilities further exacerbates the endurance problem, which seriously limits the drone's mission coverage. Therefore, how to extend the drone's endurance or achieve unmanned rapid resupply has become a technical problem that needs to be solved urgently.

[0103] (2) Poor signal stability: Existing drone relay systems exhibit significant signal stability issues in complex electromagnetic environments (such as high-voltage transmission lines, urban buildings, or other interference areas). For example, the strong electromagnetic fields around high-voltage lines may cause signal attenuation or distortion, or even cause communication interruption; and in urban buildings, multipath effects and frequency band conflicts can also significantly reduce signal transmission quality. In addition, the coverage of a single drone relay node is limited, and multiple nodes are usually required to work together to expand network coverage. However, existing technologies lack efficient scheduling algorithms, making it difficult to achieve seamless switching between nodes and optimal resource allocation. This problem of poor signal stability and limited coverage has seriously affected the reliability and efficiency of drone relay systems in practical applications.

[0104] (3) Low deployment flexibility: Current drone relay nodes mostly rely on fixed base stations or manual deployment, making it difficult to achieve unmanned dynamic adjustment, slow response speed, and unable to adapt to sudden mission requirements. For example, in natural disasters or emergencies, the rapid deployment capability of relay nodes is crucial, but existing solutions often require manual intervention for position adjustment and equipment debugging, resulting in extended response time and affecting mission execution efficiency. In addition, the deployment location of fixed base stations is limited and cannot flexibly cover dynamically changing communication blind spots. Although drone relay nodes have a certain degree of flexibility, their scheduling and management still rely on manual operation and have a low level of intelligence. This lack of deployment flexibility makes the drone relay system weak in responding to dynamic mission requirements and difficult to meet the requirements of modern emergency support and diversified mission scenarios.

[0105] Based on this, the present application proposes a drone charging device that can stably dock the drone.

[0106] In one embodiment, Figure 1 As shown, a drone charging device is provided, including: a charging platform 01 and a tower 02, the charging platform 01 is fixed on the tower 02, the charging platform 01 includes: a bearing plane 10, at least one group of sliding control components 20 arranged on one side of the bearing plane 10 and arranged oppositely, two oppositely arranged push rods 30 arranged on each group of sliding control components 20, the first side of the bearing plane 10 is used to carry the drone, the controller 40 arranged on the second side of the bearing plane 10 is connected to the at least one group of sliding control components 20, and the second side is arranged opposite to the first side; the controller 40 is used to control the at least one group of sliding control components 20 to work after the drone lands on the first side of the bearing plane 10, so as to adjust the two oppositely arranged push rods 30 to abut against the two sides of the drone.

[0107] In an embodiment of the present application, the charging platform 01 includes a load-bearing plane 10, at least one set of sliding control components 20 and a controller 40. The load-bearing plane 10 includes two contact surfaces, namely a first side and a second side. The first side is the side that carries the drone, that is, the side close to the top of the tower 02, and the second side is the side opposite to the first side. At least one set of sliding control components 20 is used to fix the drone that has landed on the load-bearing platform to make the drone more stable and can still dock stably in bad weather. The sliding control components 20 can be all arranged on the first side, or partially arranged on the first side and partially arranged on the second side. Specifically, the sliding control components 20 include slide rails and push rods 30. In each set of sliding control components 20, the push rods 30 are arranged perpendicular to the slide rails, and each push rod 30 is arranged on two slide rails, so that the push rods 30 can slide on the two slide rails. The push rods 30 are all arranged on the first side of the load-bearing plane 10. The slide rails can be arranged on the first side of the load-bearing plane 10 or on the second side of the load-bearing plane 10. When the slide rails are located on the first side, the two ends of the push rod 30 are respectively located on the two slide rails. When the slide rails are located on the second side, the push rod 30 located on the first side is connected to the two slide rails via a bent connecting assembly. In this embodiment of the present application, after the drone lands on the first side of the load-bearing surface 10, at least one set of sliding control assemblies 20 is controlled to operate to adjust the two oppositely disposed push rods 30 to abut against the sides of the drone.

[0108] For example, two parallel slide rails and two push rods 30 arranged on the two parallel slide rails constitute a set of sliding control components 20. Figure 2 and Figure 3 For example, the charging platform 01 includes two sets of sliding control components 20. Figure 2 is a schematic diagram of the first side of the carrying plane 10, Figure 3 is a schematic diagram of the second side of the carrying plane 10, Figure 2 The slide rail corresponding to the push rod 30 arranged longitudinally is arranged on the second side, and the slide rail corresponding to the push rod 30 arranged transversely is arranged on the first side. Figure 3 The second side is provided with Figure 2 The push rod 30 arranged longitudinally in the middle corresponds to the slide rail and the controller 40.

[0109] Optionally, the controller 40 may include a control module and a charging module. The control module may include a stepper motor driver, an MCU core board, a power control relay, a 5V power input, a general IO and a limit switch acquisition module, etc.; the charging module may include a power monitoring component, an electronic switch, a drone switch relay, a charging channel switching relay, a charging saturation judgment circuit and a charging power switch relay.

[0110] Optional, such as Figure 2As shown, the first side further includes at least one infrared sensor 90; the at least one infrared sensor 90 is disposed on the first side; the at least one infrared sensor 90 is used to determine the position information of the drone and transmit the position information to the controller 40. The controller 40 is used to send a position adjustment instruction to the drone based on the position information and the center position of the carrying surface 10. The position adjustment instruction is used to instruct the drone to land at the center position of the carrying surface 10. The infrared sensor 90 actively emits a modulated infrared light beam (usually emitted by an infrared light-emitting diode) to detect whether an object reflects or blocks the light beam. Based on the detection result, the position information of the drone relative to the infrared sensor 90 is determined. The controller 40 further obtains this position information and, based on the position information and the center position of the carrying surface 10, determines a position adjustment strategy for the drone. Furthermore, based on the position adjustment strategy, the controller 40 sends a position adjustment instruction to the drone, causing the drone to adjust its position according to the position adjustment instruction, thereby landing the drone at the center position of the carrying surface 10.

[0111] Optionally, the location information includes at least one of the distance, horizontal offset, vertical height, and angular deviation between the infrared sensor 90 and the drone.

[0112] Optionally, controller 40 is specifically configured to determine a target offset of the drone relative to the center of carrying surface 10 based on the position information and the center position of carrying surface 10; the target offset is included in the position adjustment instruction. Specifically, controller 40 may determine the target offset as the horizontal offset between infrared sensor 90 and the drone; alternatively, controller 40 may determine the target offset based on the distance and angular offset between infrared sensor 90 and the drone; alternatively, controller 40 may determine the target offset based on the vertical height and angular offset between infrared sensor 90 and the drone. Alternatively, infrared sensor 90 may be located at any position on carrying surface 10.

[0113] For example, Figure 4 As shown, at least one infrared sensor 90 includes a first sensor 901, a second sensor 902, a third sensor 903 and a fourth sensor 904; the first sensor 901, the second sensor 902, the third sensor 903 and the fourth sensor 904 are respectively arranged at the four corners of the first side of the carrying plane 10; the controller 40 is used to send a position adjustment instruction to the drone based on the position information determined by the first sensor 901, the second sensor 902, the third sensor 903 and the fourth sensor 904 and the center position of the carrying plane 10.

[0114] For example, during the landing process, the drone is first accurately identified and located using infrared sensors 90 located at the four corners of the first side of the support surface 10. Infrared sensors 90 utilize highly sensitive thermal imaging technology to detect the thermal radiation signals from the drone's fuselage and power system in real time, and combine this with spatial geometry algorithms to generate the drone's three-dimensional position data. When the drone approaches the platform, infrared sensors 90 acquire the drone's position information, including key parameters such as horizontal offset, vertical height, and angular deviation, at a millisecond-level response speed. This position information is rapidly transmitted to the MCU core board in the controller 40 via a high-speed signal transmission line. The MCU core board processes and analyzes the received data in real time, utilizing a built-in intelligent algorithm model (such as a PID control algorithm or a Kalman filter algorithm) to determine the precise offset of the drone relative to the center of the support surface 10. Based on this determination, the MCU core board generates position adjustment instructions to ensure that the drone accurately aligns with the center of the support surface 10. During the landing process, the infrared sensors 90 continuously monitor the drone's position changes and feed real-time data back to the MCU core board, forming a closed-loop control circuit. This closed-loop mechanism dynamically corrects for minor deviations during the drone's landing process, ensuring precise alignment even in complex environments. Through the efficient collaboration of the infrared sensor 90 and the MCU core board, the platform is able to perform high-precision spatial positioning and alignment operations during the drone's landing phase, laying a solid foundation for subsequent charging and docking.

[0115] The drone charging device comprises a charging platform and a tower, wherein the charging platform is fixed to the tower. The charging platform includes a load-bearing plane, at least one set of sliding control assemblies disposed oppositely to one side of the load-bearing plane, and two oppositely disposed push rods disposed on each set of sliding control assemblies. The first side of the load-bearing plane is used to support the drone, and a controller disposed on the second side of the load-bearing plane is connected to the at least one set of sliding control assemblies, the second side being disposed oppositely to the first side. The controller is configured to control the at least one set of sliding control assemblies to operate after the drone lands on the first side of the load-bearing plane, thereby adjusting the two oppositely disposed push rods to abut against the sides of the drone. By controlling the at least one set of sliding control assemblies and the at least two oppositely disposed push rods to abut against the sides of the drone to secure the drone to the charging platform, the stability of the drone's docking is improved. Even when the docking environment is unstable due to weather factors, the drone can still be stably docked.

[0116] In one embodiment, Figure 5 and Figure 6As shown, the at least one group of sliding control components 20 includes: a first group of sliding control components 201 and a second group of sliding control components 202, the first group of sliding control components 201 includes a first slide rail 2011 and a second slide rail 2012 arranged opposite to each other, the second group of sliding control components 202 includes a third slide rail 2021 and a fourth slide rail 2022 arranged opposite to each other, the first slide rail 2011 is provided with a first stepper motor 2013, the second slide rail 2012 is provided with a second stepper motor 2014, the third slide rail 2021 is provided with a third stepper motor 2023, and the fourth slide rail 2022 is provided with a third stepper motor 2024. A fourth stepper motor 2024 is provided on the rail 2022; a first push rod 301 and a second push rod 302 are provided on the first group of sliding control components 201, and a third push rod 303 and a fourth push rod 304 are provided on the second group of sliding control components 202; the controller 40 is used to control the operation of the first stepper motor 2013 and the second stepper motor 2014 to move the position of the first push rod 301 and / or the second push rod 302; and is also used to control the operation of the third stepper motor 2023 and the fourth stepper motor 2024 to move the position of the third push rod 303 and / or the fourth push rod 304.

[0117] In the embodiments of this application, Figure 5 is a schematic diagram of the first side of the load-bearing plane, Figure 6 This is a schematic diagram of the second side of the load-bearing plane. At least one set of sliding control components 20 includes: a first set of sliding control components 201 and a second set of sliding control components 202. The first set of sliding control components 201 is provided with a first push rod 301 and a second push rod 302. The second set of sliding control components 202 is provided with a third push rod 303 and a fourth push rod 304. That is, the controller 40 can control the four push rods 30 to abut against both sides of the drone. In the embodiment of the present application, as Figure 5 As shown, the first slide rail 2011 and the second slide rail 2012 of the first group of sliding control components 201 are arranged on the first side, as shown in FIG. Figure 6 As shown, the third slide rail 2021 and the fourth slide rail 2022 of the second set of sliding control components 202 are arranged on the second side.

[0118] In an embodiment of the present application, after the drone successfully lands, the first stepper motor 2013, the second stepper motor 2014, the third stepper motor 2023 and the fourth stepper motor 2024 work together to drive the first push rod 301, the second push rod 302, the third push rod 303 and the fourth push rod 304 respectively to complete the precise positioning and fixing operation of the drone. The collaborative working process is achieved through a high-precision mechanical transmission system. Specifically, the first stepper motor 2013 is connected to the first push rod 301 through the first longitudinal coupling 2015, the first stepper motor 2013 is connected to the second push rod 302 through the second longitudinal coupling 2016, the second stepper motor 2014 is connected to the first push rod 301 through the third longitudinal coupling 2017, and the second stepper motor 2014 is connected to the second push rod 302 through the fourth longitudinal coupling 2018, converting the rotational motion of the stepper motor into linear motion, thereby driving the first push rod 301 and the second push rod 302 along the first longitudinal slide rail 2011 and the second longitudinal slide rail 2018. The second slide rail 2012 slides up and down. Similarly, the third stepper motor 2023 is connected to the third push rod 303 via a first transverse coupling 2025. The third stepper motor 2023 is connected to the fourth push rod 304 via a second transverse coupling 2026. The fourth stepper motor 2024 is connected to the third push rod 303 via a third transverse coupling 2027. The fourth stepper motor 2024 is connected to the fourth push rod 304 via a fourth transverse coupling 2028. This converts the stepper motor's rotational motion into linear motion, thereby driving the third and fourth push rods 303 and 304 to slide left and right along the longitudinal third and fourth slide rails 2021 and 2022. The first, second, third, and fourth push rods 301, 302, 303, and 304 together form a dynamically adjustable "well"-shaped structure, capable of flexibly adjusting the spacing based on the size and shape of the drone to accommodate the docking requirements of different drone models, ensuring their precise and stable positioning on the platform.

[0119] Optionally, the controller 40 is also used to monitor the position and motion state of each push rod 30 to ensure that each push rod 30 operates within a preset safety range. During the entire push rod 30 adjustment process, the eight-way limit switch acquisition module in the controller 40 plays a key role. This module monitors the position and motion state of each push rod 30 in real time to ensure that it operates within a safe range. Specifically, each set of limit switches corresponds to the movement direction and extreme position of a push rod 30. When the push rod 30 moves to the preset safety boundary, the limit switch will immediately trigger a stop signal to interrupt the further action of the stepper motor, thereby preventing the push rod 30 from damaging the mechanical structure due to excessive movement or causing a collision risk to the drone. In addition, the feedback data of the limit switch acquisition module will also be transmitted to the MCU core board in real time for processing to form a closed-loop control system, further improving the accuracy and reliability of the push rod 30 adjustment.

[0120] In the above-mentioned application embodiment, through the precise push rod adjustment mechanism, the overlapping platform can not only firmly fix the UAV in the center position of the load-bearing plane, but also effectively disperse the weight load of the UAV to avoid the risk of overturning due to the shift of the center of gravity; at the same time, the "well"-shaped structure design also significantly enhances the stability of the UAV on the platform, and can ensure that the UAV always remains in the best position even in strong winds or other external interference conditions, providing solid protection for subsequent charging docking and mission execution.

[0121] In one embodiment, Figure 7 and Figure 8 As shown, the charging platform 01 also includes: a first charging interface 50 and a power module 60, the first charging interface 50 is arranged on the first side of the carrying plane 10, and the power module 60 is arranged on the second side of the carrying plane 10; the power module 60 connects the first charging interface 50 and the controller 40; the controller 40 is also used to control the power module 60 to supply power to the first charging interface 50, and the charging interface is used to charge the drone.

[0122] In this embodiment, the first charging port 50 is located in the center of the first side of the support surface 10. Once the drone is secured by the push rod 30, the first charging port 50 automatically docks with the charging contacts on the bottom of the drone. Once docked, the electronic switch in the power module 60 activates, entering a charging readiness state and paving the way for subsequent charging.

[0123] Optionally, during the charging process, the controller 40 implements a power monitoring function by collecting voltage and current data in the charging circuit in real time, ensuring the safety and efficiency of the charging process. Specifically, the power monitoring component monitors charging parameters at a millisecond sampling frequency and transmits the collected data to the MCU core board in the controller 40 for analysis and processing. If an abnormal voltage fluctuation (such as overvoltage or undervoltage) or current abnormality (such as overcurrent or short circuit) is detected, the controller 40 immediately triggers a protection mechanism, cutting off the charging output via the charging power switch relay, effectively protecting the drone battery from damage and extending its service life. Simultaneously, during the charging process, the controller 40 continuously monitors the charging status of the drone battery via a charge saturation determination circuit. The charge saturation determination circuit accurately determines the battery's charging progress based on multi-dimensional data such as the battery's voltage variation curve, current decay trend, and temperature. When the battery is close to saturation, the controller 40 issues a command to the power module 60 to cut off the charging output via the charging power switch relay, preventing battery performance degradation or safety hazards caused by overcharging. This intelligent charging management mechanism not only improves charging efficiency but also significantly enhances the safety and reliability of the system.

[0124] Optionally, throughout the charging process, the controller 40 maintains communication with external systems via the universal IO module, supporting remote monitoring and fault diagnosis. Using the standard TTL protocol, the universal IO module can upload key charging data (such as real-time voltage, current, and battery status) to an external monitoring system, allowing operators to remotely monitor charging progress and platform operating status. Furthermore, if an abnormality occurs during charging (such as equipment failure or environmental interference), the controller 40 sends an alarm signal to the external system via the universal IO module and provides detailed fault information, facilitating rapid problem location and appropriate resolution.

[0125] Optionally, the control module and the charging module are detachably connected via a control interface.

[0126] In the above-mentioned application embodiment, a high-precision mechanical positioning system and an intelligent control algorithm are used to ensure close and stable contact between the first charging interface and the drone contact, thereby avoiding charging interruption or energy loss due to poor contact.

[0127] In one embodiment, Figure 9 and Figure 10 As shown, the charging platform 01 further includes a solar charging connection component 70, which is arranged at the edge of the charging platform 01; the solar charging connection component 70 includes: a second charging interface 701; Figure 10 As shown, the tower 02 includes a solar panel 80 , and the second charging interface 701 is connected to the solar panel 80 and the power module 60 .

[0128] In the embodiment of the present application, in order to realize the recycling of green energy, the charging platform 01 includes a solar charging connection component 70. The system is centered on the second charging interface 701, which is connected to an external solar device, such as Figure 11 The solar panel 80 shown. The solar panel 80 converts light energy into electrical energy through efficient photovoltaic technology, and transmits the converted electrical energy to the power module 60 via the second charging port 701 for storage.

[0129] Optionally, the power module 60 supplies power to the controller 40 through a 5V power input to ensure that the controller 40 can operate normally under various working conditions; at the same time, the power module 60 also provides the charging energy required by the drone to the first charging interface 50, supporting efficient charging operations of the drone.

[0130] Optionally, the second charging port 701 is connected to the first charging port 50; the controller 40 is further configured to control the solar panel 80 to supply power to the first charging port 50 via the first charging port 50. The solar panel 80 converts solar energy into electrical energy and transmits the electrical energy to the second charging port 701. Under the control of the controller 40, the electrical energy is transmitted from the second charging port 701 to the first charging port 50 to charge the drone.

[0131] In the above application embodiment, the power module is used as the energy hub of the entire platform, which can not only efficiently store solar power, but also has an intelligent energy distribution function, providing stable and reliable power support for each module of the platform, and significantly improving energy utilization efficiency and reducing energy loss.

[0132] In one embodiment, Figure 8 As shown, the above-mentioned charging platform 01 also includes: a backup power supply module 100 arranged on the second side of the carrying plane 10, and the backup power supply module 100 is connected to the first charging interface 50 and the controller 40; the controller 40 is also used to monitor the power status, charging and discharging efficiency and switching status of the power module 60.

[0133] In the embodiment of the present application, the backup power module 100 can be a built-in energy storage battery, or the backup power module 100 can be connected to other external power sources to ensure that the platform can continue to operate stably under any circumstances and avoid functional failure or task delays caused by energy interruptions. Optionally, the backup power module 100 can be directly connected to the first charging interface 50 and the controller 40, and the backup power module 100 directly supplies power to the first charging interface 50 and the controller 40; or the backup power module 100 can be connected to the power module 60, and connected to the first charging interface 50 and the controller 40 through the power module 60, and the backup power module 100 transmits electrical energy to the power module 60, and the power module 60 then supplies power to the first charging interface 50 and the controller 40.

[0134] Optionally, the controller 40 is also used to control the backup power module 100 to charge the drone and control the backup power module 100 to power the drone charging device when the output power of the power module 60 and / or the solar panel 80 is lower than a preset threshold. For example, the MCU core board in the controller 40 can monitor the power status, charging and discharging efficiency, and switching status of the backup power supply of the power module 60 in real time. For example, when it is detected that the power generation of the solar panel 80 is lower than a preset threshold, the controller 40 will issue an early warning and adjust the power consumption strategy to give priority to ensuring the power supply of key modules.

[0135] Optionally, the power status, charge and discharge efficiency, and backup power supply switching status of the source module can be transmitted to an external system through the general IO module to support remote monitoring and energy optimization management.

[0136] Optionally, the backup power module 100 is connected to the second charging port 701, and the controller 40 is further configured to prepare the power module 100 for storing the electrical energy converted from solar energy by the solar panel 80. The solar panel 80 converts light energy into electrical energy using efficient photovoltaic technology and transmits the converted electrical energy to the backup power module 100 via the second charging port 701 for storage.

[0137] In the above application embodiment, the introduction of a backup power module not only improves the sustainability of the platform, but also greatly reduces the dependence on the external power grid, providing strong support for the long-term operation of drones in remote areas or complex environments.

[0138] In one embodiment, Figure 12 and Figure 13 As shown, the above-mentioned drone charging equipment also includes: a signal repeater 03, which is arranged at the edge of the charging platform 01, and is used to receive and forward wireless communication signals between the ground control center and the drone.

[0139] In this embodiment, the helipad is expanded into a multifunctional platform with communication relay capabilities. This design transcends the limitations of the helipad's limited functionality as physical support and energy supply, making it a critical communication node for drone mission execution, particularly suitable for communication needs in complex environments. Signal repeater 03, deployed on one side of the helipad, receives wireless communication signals from the ground control center, amplifies them, and retransmits them, significantly expanding signal coverage. Its multi-band compatibility supports various communication protocols (such as 2.4 GHz, 5.8 GHz, and other specialized frequency bands), adapting to different scenarios and effectively avoiding channel congestion and interference.

[0140] Optionally, the signal repeater 03 can also work in conjunction with other communication infrastructure (such as satellite communications or cellular networks) to build a more complete communication network architecture and provide technical support for long-distance UAV missions.

[0141] In the above-mentioned application embodiments, in remote areas or environments with weak communication infrastructure, the signal repeater can make up for insufficient signal coverage and ensure that the UAV always maintains a stable communication link when performing tasks; it realizes the deep integration of the apron and the communication network; in the multi-UAV collaborative operation scenario, the signal repeater can serve as a regional communication hub, dynamically managing the communication links between UAVs and data interaction with the ground control center, reducing dependence on direct communication, and improving system operation efficiency and robustness; making full use of the structural characteristics of the apron to achieve efficient functional integration without increasing additional space occupancy.

[0142] In one embodiment, Figure 3As shown, the above-mentioned charging platform 01 also includes: a first supporting foot 401, a second supporting foot 402 and a third supporting foot 403 arranged on the second side of the supporting plane 10, the first supporting foot 401 and the second supporting foot 402 are arranged in parallel, the third supporting foot 403 is arranged to intersect with the first supporting foot 401 and the second supporting foot 402 in sequence, and the third supporting foot 403 is arranged perpendicular to the first supporting foot 401.

[0143] In an embodiment of the present application, in order to ensure the stability and reliability of the platform in a complex environment, horizontal support legs and longitudinal support legs are designed on the back of the platform. The horizontal support frame includes a first support leg 401 and a second support leg 402. The first support leg 401 and the second support leg 402 are arranged in parallel. The longitudinal support leg includes a third support leg 403. The third support leg 403 is arranged to intersect with the first support leg 401 and the second support leg 402 in sequence, and the third support leg 403 is arranged perpendicular to the first support leg 401. The first support leg 401, the second support leg 402 and the third support leg 403 together constitute an "I"-shaped structure, and the design of the "I"-shaped structure minimizes material usage while ensuring strength, thereby ensuring lightweight and efficient installation.

[0144] In the above-mentioned application embodiment, the structure of the first support leg, the second support leg and the third support leg not only significantly enhances the overall rigidity of the platform, but also effectively disperses the load, reduces mechanical fatigue caused by long-term use or external environmental stress, thereby extending the service life of the platform and improving its operational stability.

[0145] In one embodiment, Figure 1 and Figure 3 As shown, the above-mentioned charging platform 01 also includes a first axis connection structure 404 and a second axis connection structure 405, and the drone charging equipment also includes a first bracket 04, which is vertically arranged on the tower 02; the first axis connection structure 404 is arranged on the first support foot 401, and the second axis connection structure 405 is arranged on the second support foot 402; the first axis connection structure 404 is also connected to the first bracket 04, and the second axis connection structure 405 is also connected to the first bracket 04.
