Description

Technical Field

[0001] This invention relates to the field of drone auxiliary equipment technology, and more specifically, to a biomimetic temperature-controlled drone charging compartment and an intelligent temperature control method. Background Technology

[0002] With the popularization of drone technology, the demand for outdoor drone charging stations is growing. However, existing drone charging stations have obvious technical limitations.

[0003] 1. Inflexible Thermal Management: For example, Chinese patent CN215830135U discloses "A Solar Charging Cabin," in which solar panels are installed on the outer surface of the cabin. Under hot, sunny conditions, heat accumulates inside the cabin due to equipment operation (such as batteries and wireless charging modules) and sunlight, making effective heat dissipation difficult. This leads to excessively high cabin temperatures, severely impacting battery cycle life and charging safety. Conversely, if fixed ventilation openings are installed, it becomes difficult to cope with sudden wind and rain.

[0004] 2. Delayed Environmental Awareness and Response: Most charging cabins lack the ability to sense the environment in advance and are only equipped with local sensor groups, such as the "Solar-Powered Drone Cabin for Damage Prevention in Severe Weather" (patent number CN213535144U) and the "Drone Cabin for High-Altitude Environmental Inspection" (patent number CN222330038U). The response of the sensor group is based on threshold triggering and lacks predictability. It is impossible to close the cabin in advance before heavy rain or start heat dissipation in advance when the high temperature trend is forming.

[0005] 3. Single energy supply: The charging compartment relies on the power grid or a single battery for power supply, which makes it difficult to deploy in remote areas without mains power, and its range is insufficient in rainy weather.

[0006] 4. Poor wind resistance and aerodynamic shape: Existing drone hangars generally adopt rigid cabin structures. For example, Chinese patent CN215830135U discloses "A drone hangar set on a pole". Although the hangar can provide basic protection, the square cabin has high resistance in strong winds, which poses a risk of overturning. In addition, the airflow is prone to turbulence around the cabin, which is not conducive to the take-off and landing of drones.

[0007] Therefore, there is an urgent need for a drone charging cabin solution that integrates intelligent sensing, adaptive adjustment, efficient energy utilization, and excellent aerodynamic shape. Summary of the Invention

[0008] To address the shortcomings of existing technologies, the present invention aims to provide a biomimetic temperature-controlled drone charging cabin and an intelligent temperature control method. This invention uses sensors to detect environmental conditions in real time and adjusts the operating mode accordingly, achieving an optimal dynamic balance between protection and heat dissipation, and enhancing the self-sufficiency of power energy and endurance.

[0009] To achieve the above objectives, the present invention provides the following technical solution: A biomimetic temperature-controlled drone charging cabin includes a base system, a blade assembly, and an intelligent control system. The intelligent control system is located within the base system, which includes a base and a support frame. The base and support frame house the charging system, a sensor group, and a drive motor. The blade assembly is connected to the base and includes several movable blades. The connection end between the movable blades and the base is provided with a rotating shaft for realizing the opening and closing state of the movable blades. The rotating shaft is connected to the drive motor, and the movable blades are located near one end of the rotating shaft. The intelligent control system receives signals output by the sensor group, and the drive motor is controlled by the output signals of the intelligent control system. The signal output end of the intelligent control system is also connected to an electromagnetic lock array.

[0010] Furthermore, a flexible solar thin-film battery layer is provided on the outer wall of the movable blade, and the output end of the flexible solar thin-film battery layer is connected to a battery pack.

[0011] Furthermore, the movable blade has a teardrop-shaped arc-shaped thin sheet structure, with the end away from the base bent inward and the end near the base equipped with a hook that matches the electromagnetic lock. The edge of the movable blade is equipped with a mounting groove for the sealing strip.

[0012] Furthermore, the electromagnetic lock array includes electromagnetic locks configured with all movable blades, the positions of which correspond to the installation positions of the movable blades.

[0013] Furthermore, it also includes a wireless communication module, which is connected to the intelligent control system.

[0014] Furthermore, the charging system includes a wireless charging module for contactless charging of the drone, and a battery pack for powering the intelligent control system, sensor group, electromagnetic lock array and drive motor. The wireless charging module is fixed in the center of the base cavity, and the plane of the transmitting coil is slightly lower than the surface of the base's landing platform; the battery pack is placed inside the base.

[0015] A smart temperature control method for a biomimetic temperature-controlled drone charging compartment is provided. Based on the aforementioned biomimetic temperature-controlled drone charging compartment, a sensor group detects the current environmental state of the biomimetic temperature-controlled drone charging compartment. The intelligent control system receives signals from the sensor group and the wireless communication module, and controls the drive motor and electromagnetic lock array to work together to enable the biomimetic temperature-controlled drone charging compartment to select a working mode that matches the current environmental state in different environments.

[0016] Furthermore, the operating modes include standby sealing mode, intelligent heat dissipation mode, and full-open take-off and landing mode. The activation conditions for each operating mode are as follows: Standby sealing mode: When the sensor group detects rainfall, wind speed exceeding the safety threshold, or rainfall forecast by the weather base station, or when there is no need for heat dissipation or take-off and landing, the intelligent control system outputs control signals to the drive motors. All drive motors close all movable blades to a fully closed state, and the electromagnetic lock array is energized to lock the hooks at the bottom of all movable blades, achieving complete sealing and locking of the bionic temperature-controlled drone charging cabin and protecting the equipment inside the cabin. Intelligent heat dissipation mode: When the temperature inside the charging compartment of the bionic temperature-controlled drone exceeds the set upper limit and the current weather conditions are windless and rainless or the wireless communication module receives information from the weather base station that the temperature will continue to be high, the intelligent control system will drive the drive motor and electromagnetic lock of the downwind movable blades according to the real-time wind direction collected by the sensor group. The downwind movable blades will open to the preset angle position to achieve convection heat dissipation inside the compartment. Fully open take-off and landing mode: When the drone needs to enter or exit the bionic temperature-controlled drone charging cabin, all electromagnetic locks are released, and the drive motors synchronously drive all movable blades to unfold to the maximum angle, forming a completely open and unobstructed take-off and landing platform.

[0017] In summary, the invention has the following beneficial effects: This invention utilizes meteorological base station data and real-time data from multiple sensors to form a dual-sensor decision-making system combining real-time response and predictive early warning. This makes the adjustment of the operating mode more forward-looking and proactive, significantly improving reliability under complex and variable climates. The biomimetic temperature-controlled UAV charging cabin adjusts different operating modes based on environmental data. The biomimetic opening and closing structure, combined with the intelligent control system, solves the problem of traditional fixed cabins being "sealed but not dissipating heat, or dissipating heat but not sealing." The intelligent heat dissipation mode utilizes aerodynamic principles for directional ventilation, achieving high efficiency and low energy consumption, realizing the optimal dynamic balance between protection and heat dissipation. Flexible solar cells are installed on the outer wall of multiple blade structures, combined with a streamlined curved surface structure to reduce wind resistance, reducing the overall structural load and energy loss under severe weather conditions, and improving the stability and safety of the invention in strong wind environments. A large-capacity battery, combined with efficient solar charging, ensures at least 7 days of flight time in cloudy and rainy weather, greatly expanding the application range of this invention in areas without power grids. The fully open mode provides ample take-off and landing space, reducing the difficulty of UAV operation and the risk of collisions; the dual-sealing structure of electromagnetic locks and mechanical hooks ensures cabin safety under extreme weather conditions.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] It should be noted that, for ease of description, the descriptions of direction in the following text are consistent with the directions in the accompanying drawings, but they do not limit the structure of the present invention.

[0022] like Figures 1-6As shown, this invention discloses a biomimetic temperature-controlled drone charging compartment, including a base system, a blade assembly, and an intelligent control system. The intelligent control system 4 is placed within the base system. The base system includes a base 1 and a support frame 10. The base 1 has a flat surface for parking the drone. The charging system, sensor group 5, and drive motor are installed inside the base 1 and support frame 10. Dustproof ventilation holes and drainage holes are also arranged on the shells of the base 1 and support frame 10 to ensure heat dissipation and moisture protection for the electrical components inside the base. The charging system includes a wireless charging module 2 for contactless charging of the drone, and a battery pack 3 to power the intelligent control system, sensor group 5, electromagnetic lock array 6, and drive motor. The wireless charging module is fixed in the center of the inner cavity of the base 1. To protect the transmitting coil from damage and ensure stable landing of the drone, the transmitting coil is installed inside the base. The transmitting coil, a component of the wireless charging module (not marked in the attached diagram), is the output terminal of the wireless charging module. Its function is to convert electrical energy into an alternating magnetic field, inducing a current in the drone's receiving coil, thereby charging the drone. The energy flow during the charging process is: solar thin-film battery → battery → transmitting coil → drone battery. To minimize the impact of magnetic field attenuation and provide physical protection, the transmitting coil plane is positioned as close as possible to the inner surface of the landing platform of the base 1. The battery pack 3 is placed inside the base 1. This invention uses magnetic resonance wireless power transmission technology with a charging efficiency of no less than 85%, used for non-contact charging of docked drones. The battery pack 3 is located at the center of gravity inside the support frame 10, using a large-capacity lithium iron phosphate battery pack. The battery capacity allows the charging cabin to operate for no less than 7 consecutive cloudy or rainy days relying solely on its own solar power. The battery pack provides operating power to the control unit, sensor group, drive motor, and electromagnetic lock array through a power management circuit, and charges the drone through the wireless charging module.

[0023] The blade assembly is connected to the base 1 and includes several movable blades 2. In the illustrated embodiment, there are four movable blades, with a minimum of two. A rotating shaft is provided at the connection end between the movable blades 2 and the base 1 to realize the opening and closing state of the movable blades 2. The rotating shaft is connected to a drive motor. Near the rotating shaft, the energy collection surface formed by the outer surfaces of multiple movable blades 2, when closed, encloses a teardrop-shaped streamline, effectively guiding airflow and significantly reducing wind resistance. The length-to-diameter ratio of the teardrop-shaped streamline is 1.2:1 to 1.5:1, effectively reducing the drag coefficient, thus lowering the drag coefficient of the charging compartment when closed compared to a cubic compartment of the same volume. A flexible solar thin-film battery layer 22 is provided on the outer wall of the movable blades 2, and the output end of the flexible solar thin-film battery layer 22 is connected to a battery pack 3. Solar energy is converted into electrical energy and stored in battery pack 3. The movable blade 2 has a teardrop-shaped arc-shaped thin sheet structure, with the end away from the base 1 bent inward. The arc-shaped outer surface forms a certain angle of inclination towards the sun, increasing the effective light receiving area. The end near the base 1 is provided with a hook 24 that matches the electromagnetic lock. The electromagnetic lock and the hook 24 cooperate to achieve a seal for sealing the blade of the charging base station. The edge of the movable blade 2 is provided with a sealing strip mounting groove 23, with an embedded silicone sealing strip. When the movable blade 2 is closed, the sealing strips between adjacent blades are squeezed against each other to form a waterproof sealing structure. The electromagnetic lock array 6 includes electromagnetic locks configured for all movable blades 2. The position and number of electromagnetic locks correspond to the installation position and number of movable blades 2. Each electromagnetic lock cooperates with the hook 24 at the bottom of the movable blade 2. It is locked by electromagnetic attraction and released by power failure.

[0024] The intelligent control system 4 receives signals from the sensor group 5, which includes a rain sensor mounted on the outer surface of the movable blade 2, a wind speed and direction sensor mounted on the top of the movable blade 2, and temperature and humidity sensors distributed inside and outside the cabin. These sensors provide real-time local data to the intelligent control system. The wireless communication module is used to receive weather forecast data from the meteorological base station. The intelligent control system 4 pre-adjusts the working status of the charging cabin based on the data from the meteorological base station. The drive motor is controlled by the signal output from the intelligent control system 4. The signal output terminal of the intelligent control system 4 is also connected to the electromagnetic lock array 6, which can realize the individual adjustment of any movable blade 2 based on the wind speed and direction sensors.

[0025] The present invention also includes a wireless communication module, which is connected to the intelligent control system 4.

[0026] This invention also discloses an intelligent temperature control method for a biomimetic temperature-controlled drone charging compartment. Based on the aforementioned biomimetic temperature-controlled drone charging compartment, sensor group 5 detects the current environmental state of the biomimetic temperature-controlled drone charging compartment. The intelligent control system 4 receives signals from sensor group 5 and wireless communication module, and controls the drive motor and electromagnetic lock array to work together to enable the biomimetic temperature-controlled drone charging compartment to select a working mode that matches the current environmental state in different environments.

[0027] The operating modes include standby sealing mode, intelligent heat dissipation mode, and full-open start-up and drop mode. The activation conditions for each operating mode are as follows: Standby sealing mode: When the sensor group 5 detects rainfall, wind speed exceeding the safety threshold, or the weather base station forecasts rainfall or there is no need for heat dissipation or take-off and landing, the intelligent control system 4 outputs control signals to the drive motors. All drive motors close all movable blades 2 to a fully closed state. The electromagnetic lock array 6 is energized to lock the hooks 24 at the bottom of all movable blades 2, achieving complete sealing and locking of the bionic temperature-controlled drone charging cabin and protecting the equipment inside the cabin.

[0028] Intelligent heat dissipation mode: When the temperature inside the bionic temperature-controlled drone charging cabin exceeds the set upper limit and the current weather conditions are windless and rainless, or the wireless communication module receives information from the weather base station that the temperature will continue to be high, the intelligent control system drives the drive motor and electromagnetic lock of the downwind movable blade 2 according to the real-time wind direction collected by the sensor group. The downwind movable blade 2 opens to the preset angle position. Utilizing Bernoulli's principle, the airflow speed increases and the pressure decreases when the airflow passes through the open blade opening, thereby forming a negative pressure inside the cabin and actively extracting the hot air inside the cabin to achieve convective heat dissipation inside the cabin.

[0029] Full-open take-off and landing mode: When the drone needs to enter or exit the bionic temperature-controlled drone charging cabin, all electromagnetic locks are released, and the drive motor synchronously drives all movable blades 2 to unfold to the maximum angle, forming a completely open and unobstructed take-off and landing platform.

[0030] In the method of this invention, a preset priority judgment logic is used: first, it is judged whether the trigger conditions for the standby sealed mode are met; if not, it is judged whether the trigger conditions for the full-open take-off and landing mode are met; if still not met, it is judged whether the trigger conditions for the intelligent heat dissipation mode are met. The intelligent control system 4 integrates dual-channel data sources to perceive the environment. In terms of weather risk judgment, when the local rain sensor does not detect rainfall, but the communication module receives a short-term weather forecast from the base station indicating that the probability of precipitation exceeds a threshold, the intelligent control system 4 comprehensively assesses that there is a risk of rainfall and enters the "standby sealed mode". This dual-mode data fusion processing significantly improves the predictability and response reliability to sudden weather changes. In terms of temperature regulation judgment, when the cabin temperature sensor detects a temperature rise but does not reach the heat dissipation threshold, if the meteorological base station predicts a sharp rise in the short-term temperature in the future, the heat dissipation demand can be assessed in advance, and the heat dissipation mode can be activated in advance or proactively. Conversely, if the weather base station predicts that the ambient temperature will drop significantly, the heat dissipation action can be optimized to reduce energy consumption while meeting the cabin temperature requirements. Based on the trend prediction of dual-mode temperature data, a smoother and more energy-efficient intelligent adjustment of the cabin temperature is achieved.

[0031] Safety thresholds, temperature limits, and preset angles can be preset in the intelligent control system 4 according to actual practical needs. The bionic temperature-controlled drone charging cabin responds and adjusts quickly by the intelligent control system 4 based on real-time environmental data (local real-time data) provided by the sensor group 5 of the base system. The intelligent control system 4 also has a wireless communication LoRa module, which can receive weather forecast data from meteorological base stations (network prediction data, such as the probability of precipitation, wind speed changes, and temperature trends in the next few hours). The intelligent control system 4 integrates local real-time data and network prediction data to pre-adjust the working status of the bionic temperature-controlled drone charging cabin in advance, such as: entering the sealing mode in advance before the predicted rainstorm; or adjusting the blades to the optimal heat dissipation angle in advance before the predicted high temperature period.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
