With the widespread application of humanoid robots in services, healthcare, education, rescue operations, industrial collaboration, and other fields, the demand for their endurance and energy autonomy is growing.

[0012] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0013] First embodiment

[0014] The first embodiment of the present application relates to a solar energy utilization device, such as Figure 1 As shown, the device includes:

[0015] A modular housing 10, wherein the housing adopts a modular design, and a flexible solar cell is customized according to the curved surface of the modular housing 10, and the flexible solar cell is adhered and mounted on the surface of the modular housing 10;

[0016] A dynamic angle adjustment mechanism 20 is provided on the surface of the modular housing 10 and is used to automatically adjust the angle of the surface of the modular housing 10 according to the ambient light;

[0017] The intelligent energy management system 30 integrates the flexible solar cell sheet and the battery to perform intelligent energy management.

[0018] Specifically, the design provided in this application uses flexible monocrystalline silicon solar cells, which are customized based on the three-dimensional surface data of the humanoid robot shell through a laser cutting process to ensure that the shape of the cell matches the shell surface. The modular shell 10 adopts a modular design, which can disassemble the robot shell into multiple independent and interchangeable unit modules such as the head, torso, and limbs. According to the unique curved surface shape of each module, an adaptive flexible solar cell can be customized so that the flexible solar cell can fit closely to the shell surface, thereby maximizing the coverage of the effective light-receiving area and improving the solar energy absorption efficiency.

[0019] For example, regarding the physical parameters and layout design of flexible solar cells, physical parameters are considered from the perspectives of thickness, flexible curvature radius, and unit weight. To meet the requirements of lightweight and flexible robots, flexible monocrystalline silicon cells can be 50-150 microns thick, while CIGS and organic thin-film cells can be 1-5 microns thick. The curvature radius of the cells at joints can be less than 10 mm, and the flat areas can be relaxed to 20-30 mm. Lightweight organic thin-film or CIGS cells can be preferred. Regarding layout strategy and path design, the principles of maximizing daylighting and adapting to robot movement can be followed. The main light-receiving areas should be evenly distributed, and the joints should be dispersed with space for expansion. The connection path can be based on the shortest distance, and serpentine or grid connections can be selected depending on the body shape. Different parts can be installed differently according to lighting conditions. High-power-density cells can be used for the head, moderately stable cells for the back, and low-power-density, highly flexible cells for the limbs.

[0020] Exemplarily, the connection between the flexible solar cell and the housing of the humanoid robot can adopt three structures: slot-block, magnetic, and bolt-nut. Each structure corresponds to different assembly and disassembly methods and application scenarios. The slot-block connection can be a slot reserved on the surface of the housing module that matches the block on the edge of the cell. During installation, it can be directly pushed in to complete the fixation. During removal, it can be separated by prying with a thin tool, which is easy to operate. The magnetic connection can be embedded in the housing and the cell respectively with opposite magnetic patches. The magnetic force is automatically attracted and positioned. It is fast to install. During removal, it can be separated by applying a pulling force. It can also accommodate certain position deviations. The bolt-nut connection requires threaded holes in the housing module and through holes in the cell. The bolts are tightened and fixed. During removal, the bolts can be unscrewed with tools. However, during installation, it is necessary to ensure that the bolts reach the appropriate tightening torque to ensure stability. The three connection structures each have their own advantages: the slot-block connection is easy to install, the magnetic connection is convenient for quick disassembly and assembly and has strong fault tolerance, and the bolt-nut connection is strong and reliable, which can meet the installation requirements of different parts of the robot. In actual applications, relevant personnel can choose according to actual needs, and this embodiment does not make any specific limitations on this.

[0021] Specifically, the dynamic angle adjustment mechanism 20 is mounted on the surface of the modular housing 10 and can be composed of a micro-servo motor, a light sensor, a bracket structure, and a connecting transmission component. Through mechanical design and intelligent control, efficient solar energy collection is achieved. In terms of specific mechanical design, lightweight aluminum alloy "X"-shaped movable brackets can be installed at key locations such as the robot's head, back, and limb joints. The middle rotating shaft of the bracket is connected to the fixed part of the housing, and the two ends can be connected to the solar cell mounting plate. A small, moderate-torque micro-servo motor is installed at each movable joint. The output shaft of the micro-servo motor is connected to the rotating shaft of the bracket. Through a transmission belt or gear set (such as the synchronous belt drive of the leg joint), the motor's rotational motion can be accurately transmitted to the bracket, driving the solar cell to smoothly adjust the angle. In terms of control strategy, the light sensor can collect data such as ambient light intensity and direction in real time and transmit it to the control system. After analysis by a preset algorithm, the control system can send instructions to the micro-servo motor, driving the motor to drive the housing surface to perform multi-axis linkage angle adjustment, ensuring that the flexible solar cell always receives light at the optimal angle, further improving the utilization of solar energy.

[0022] Specifically, the intelligent energy management system 30 realizes intelligent and refined energy management and control by integrating flexible solar cells and batteries.

[0023] Optionally, in some embodiments, the intelligent energy management system 30 can perform energy scheduling, operation status monitoring and parameter setting through a mobile APP.

[0024] Exemplarily, the intelligent energy management system 30 can support linkage with a mobile APP, and users can perform multi-dimensional operations through the APP: not only can they view data such as battery power and power generation power in real time, but they can also flexibly adjust the energy allocation strategy according to demand to complete accurate energy scheduling; they can also monitor the system operation status in real time, including the working conditions of key components such as the dynamic angle adjustment mechanism 20 and the heat dissipation channel, and receive alarms in time when abnormalities occur; at the same time, they can remotely set and modify system parameters such as maximum power point tracking parameters and angle adjustment range to meet the needs of diverse usage scenarios and achieve efficient and convenient intelligent management.

[0025] Understandably, in related technologies, humanoid robots rely on lithium batteries and tin batteries for power, but due to the physical properties of battery materials, the energy density is difficult to break through, resulting in a generally short battery life for the robots and the need for frequent charging and recharging. Traditional solar energy collection devices mostly adopt a separate design independent of the robot's main structure, which not only adds extra volume and weight, but also destroys the robot's overall motion performance. In order to achieve bionic movement, the humanoid robot shell often adopts a multi-joint curved surface structure, but traditional rigid solar panels cannot fit tightly to the curved surface due to the rigid limitations of the material. Forced installation can easily lead to stress concentration or installation gaps, which not only affects the appearance but also reduces the energy collection efficiency and is difficult to integrate. Most existing solar panels are installed at a fixed angle and cannot automatically adjust their posture according to the dynamic changes in light direction and intensity throughout the day (such as oblique sunlight in the morning and evening, direct sunlight at noon), resulting in the panels often being in a non-optimal light-receiving state, especially on cloudy days or when the light angle is offset, the solar energy utilization rate is significantly reduced. Traditional solar energy systems mostly adopt an integral design, which is difficult to disassemble and maintain in a modular manner, affecting later upgrades and applications.

[0026] Compared to related technologies, the solution provided in the embodiments of this application effectively addresses the technical challenges of existing humanoid robots through the collaborative design of a modular housing, a dynamic angle adjustment mechanism, and an intelligent energy management system. The modular housing utilizes a modular design, enabling flexible solar cells to be customized and tightly fitted to curved surfaces. This not only overcomes the difficulty of rigid solar panels adapting to complex curves, but also addresses the difficulty of upgrading solar systems due to the modular structure of the housing, which facilitates disassembly and maintenance. The dynamic angle adjustment mechanism can sense changes in ambient light in real time and automatically adjust the angle of the modular housing surface, reversing the low solar energy utilization rate caused by traditional fixed installations. The intelligent energy management system integrates flexible solar cells and batteries to achieve precise control and efficient management of electrical energy, breaking through the energy density limitations of batteries and significantly improving energy conversion efficiency and endurance. Furthermore, the integrated design of the flexible solar cells and modular housing avoids the increased volume and weight associated with separating the energy harvesting device from the housing, effectively enhancing the robot's motion performance. The close coordination and interaction of these three elements not only enhances the robot's endurance but also maintains its overall appearance, making it suitable for humanoid robots in various scenarios, such as service and rescue operations.

[0027] Second embodiment

[0028] The second embodiment of the present application relates to a solar energy utilization device. The second embodiment is an improvement on the first embodiment. Specifically, in this embodiment, the flexible solar cell sheet can be made of one of the following materials: single crystal silicon, copper indium gallium selenide, or organic thin film.

[0029] Among them, single-crystal silicon material is a high-purity silicon semiconductor material with a regular crystal structure and high electron mobility. When applied to flexible solar cells, the single-crystal silicon can convert more solar energy into electrical energy with a photoelectric conversion efficiency of up to 20%-25%, providing a stable and efficient energy supply for robots. In addition, single-crystal silicon material has excellent stability and excellent weather resistance and aging resistance. Even when used for a long time in complex outdoor environments such as high temperature and ultraviolet radiation, the performance decays relatively slowly, which can effectively extend the service life of solar cells and reduce maintenance costs. It is suitable for humanoid robots with high requirements for energy reliability.

[0030] Among them, copper indium gallium selenide (CIGS) is a multi-element compound semiconductor material whose optoelectronic properties can be optimized by precisely controlling the ratios of copper, indium, gallium, and selenium. Flexible solar cells made from this material achieve photoelectric conversion efficiencies of 15%-22%, maintaining excellent power generation capabilities even in low-light environments. This allows humanoid robots to continuously obtain a certain level of electricity even in low-light conditions such as early morning, evening, or on cloudy days. Furthermore, CIGS's excellent flexibility and thinness allow it to conform tightly to the complex curves of the robot's casing, maximizing the light-receiving area without adding excessive weight or volume, thus balancing the requirements of efficient power generation with the robot's lightweight design.

[0031] Among them, organic thin film materials are based on organic semiconductor polymers or small molecules and are made into flexible solar cells through processes such as solution spin coating and vacuum evaporation. The greatest advantage of these organic thin film materials is their extreme flexibility, which allows for large-scale flexible production. They can easily adapt to the arbitrary curved surface shape of humanoid robot shells and even support large deformations such as folding and curling to meet the needs of complex structural designs. In addition, the preparation process of these organic thin film solar cells is relatively simple, the cost is low, and they have good translucency, which can be integrated with the robot's appearance design, combining functionality and aesthetics.

[0032] It's not difficult to see that in the embodiments of this application, single-crystal silicon, copper indium gallium selenide, or organic thin films can be used as flexible solar cell materials. Using single-crystal silicon ensures efficient power generation and long-term stable operation of the robot under sufficient sunlight; using copper indium gallium selenide allows for adaptability to the robot's complex curved surfaces while providing continuous power even in low light conditions; and using organic thin film materials allows for the complex shape of the robot's shell, enabling large-scale deployment while also balancing design and cost. Any of these three options can meet the energy needs of humanoid robots in different application scenarios in terms of efficiency, environmental adaptability, structural compatibility, and cost.

[0033] Third embodiment

[0034] The third embodiment of the present application relates to a solar energy utilization device. The third embodiment is an improvement on the first embodiment, and the specific improvement is that: in this embodiment, the dynamic angle adjustment mechanism includes a micro servo motor and a light sensor.

[0035] Specifically, the dynamic angle adjustment mechanism may include a micro servo motor and a light sensor; the micro servo motor is used to drive the angle adjustment of the shell surface; and the light sensor is used to collect the ambient light data.

[0036] Among them, the dynamic angle adjustment mechanism uses a micro servo motor as the core driving component. The micro servo motor is small in size, high in precision and quick in response, and can perfectly adapt to the compact structure of the humanoid robot. Through a closed-loop control system, the micro servo motor can achieve precise angular displacement control after receiving instructions from the main control system, and drive the shell surface to adjust the angle with extremely small error. During operation, the motor can quickly respond to changes in light according to the ambient light data (such as intensity, direction, etc.) collected by the light sensor, and drive the shell to rotate to the optimal light receiving angle. For example, when the light direction changes, the shell can be driven to complete multi-angle and multi-axis linkage adjustments in a short time to ensure that the flexible solar cell always receives sunlight in the optimal posture, further improving the efficiency of solar energy absorption.

[0037] The light sensor, using the principle of photoelectric conversion, can collect ambient light data in real time and convert it into signals for transmission to the control system. The light sensor has high sensitivity and fast response, and can keenly detect subtle changes in light (such as intensity differences from early morning to evening, changes in weather, or changes in light direction caused by robot movement). This allows the control system to timely obtain light dynamics and send precise instructions to the micro-servo motor to adjust the housing angle, ensuring that the solar cell is always in the optimal light-receiving state, further improving the efficiency of solar energy utilization.

[0038] It can be seen that in this embodiment, the control strategy of the dynamic angle adjustment mechanism revolves around light data collection, motor drive control and feedback calibration, which can achieve multi-axis linkage to optimize the light receiving angle. Light sensors, such as high-precision photodiodes distributed on the robot's head, can collect ambient light intensity and angle data in real time, convert them into electrical signals and transmit them to the microcontroller. After analysis and processing, the optimal light receiving angle is obtained; then, the microcontroller can send control instructions to the micro servo motor, and the motor driver chip controls the motor speed and rotation angle, driving the bracket to adjust the angle of the battery cell; during the operation of the motor, the built-in encoder can provide real-time feedback of the rotation angle data, and the microcontroller compares the actual and target angles to calibrate the deviation in time. For example, when a robot walks outdoors and encounters oblique light from above, after the head sensor detects the change in light, the microcontroller can synchronously send instructions to the motors at the head, shoulder and arm joints. Each motor can drive the corresponding bracket to adjust in a coordinated manner, so that the battery cell is as perpendicular to the light as possible, greatly improving the utilization rate of light energy.

[0039] Optionally, in some embodiments, the dynamic angle adjustment mechanism is used to achieve multi-axis linkage to optimize the light receiving angle.

[0040] The dynamic angle adjustment mechanism can adopt multi-axis linkage technology to break through the limitations of traditional single-axis adjustment and realize multi-angle and all-round precise adjustment of the humanoid robot shell in complex and changeable lighting environments. The dynamic angle adjustment mechanism works in coordination with multiple micro-servo motors to simultaneously control the angle changes of the shell in multiple dimensions such as horizontal, vertical and tilt. For example, when sunlight shines from above, the linkage system can quickly adjust the pitch angle, yaw angle and roll angle of the shell to keep the flexible solar cell perpendicular to the light and maximize the light-receiving area; even if the direction of light continues to change during the movement of the robot, the multi-axis linkage mechanism can also be adjusted dynamically in real time to ensure that the cell is always in the optimal light-receiving posture. Compared with single-axis adjustment, it can significantly improve the efficiency of solar energy absorption and provide more sufficient energy guarantee for the long-term stable operation of the robot.

[0041] It should be noted that this embodiment may also be an improvement based on the second embodiment.

[0042] It is not difficult to find that in the embodiment of the present application, the dynamic angle adjustment mechanism adopts a combination of a micro servo motor and a light sensor. The light sensor can accurately sense the changes in parameters such as the intensity and direction of the ambient light in real time and quickly transmit the data to the control system; the micro servo motor can, with its high precision and high response speed, drive the surface of the modular shell to perform multi-angle and multi-axis linkage adjustments according to the control system instructions. The two work together to ensure that the flexible solar cell installed on the surface of the modular shell always receives light at the optimal angle, which greatly improves the efficiency of solar energy collection compared to the traditional fixed-angle installation method; at the same time, the micro servo motor is small in size and light in weight, which can avoid adding too much extra load to the robot, and the micro servo motor has stable and reliable operating performance, which can also ensure the long-term effectiveness of angle adjustment, effectively extend the service life of the device, and provide a solid energy acquisition guarantee for the long-term and efficient operation of the humanoid robot.

[0043] Fourth embodiment

[0044] The fourth embodiment of the present application relates to a solar energy utilization device. The fourth embodiment is an improvement on the first embodiment. Specifically, the improvement is that in this embodiment, the intelligent energy management system uses maximum power point tracking technology for energy management and has an energy allocation priority setting function.

[0045] Specifically, the intelligent energy management system can achieve refined energy control by integrating flexible solar cells and batteries, mainly relying on the coordinated operation of maximum power point tracking technology and energy allocation priority setting function.

[0046] For example, at the energy harvesting optimization level, the system can be equipped with maximum power point tracking (MPPT) technology, and perform real-time regulation using the perturbation observation method as an example. The system can continuously monitor the output voltage and current of the solar cell, calculate the current power, make small perturbations (increase or decrease) to the working voltage at fixed intervals, and measure and calculate the power again. If the power rises, it indicates that the perturbation direction is correct, and the adjustment will continue in this direction next time; if the power drops, the perturbation direction will be changed. By executing this algorithm through the microcontroller in the robot, the operating point can be dynamically adjusted according to changes in light and battery status, so that the solar cell always maintains the maximum power output state, further improving the energy conversion efficiency.

[0047] For example, in terms of energy distribution management, the intelligent energy management system has the function of setting energy distribution priorities. Based on the importance and energy consumption characteristics of the robot components, the main control system, motion drive system, etc. can be identified as key components. The main control system is responsible for overall control decisions and has the highest priority; the motion drive system ensures basic movement and has the second highest priority; non-critical auxiliary components such as decorative lights have a lower priority. By establishing a priority list, when there is energy input, the system can distribute electricity in order: when there is sufficient solar energy, the maximum power point tracking technology enables the battery cells to output full power, and the system prioritizes supplying electricity to the main control system to ensure the normal operation of the robot. The remaining energy is distributed in turn to the motion drive system, auxiliary sensors, communication modules, etc.; when the solar power decreases, the system can first reduce the energy supply to low-priority components, giving priority to protecting the main control system and motion drive system to maintain the basic functions of the robot.

[0048] In addition, the system can also set up energy redundancy and self-recovery mechanisms. In terms of energy redundancy, additional energy is reserved by configuring the battery capacity, and this energy is in standby mode when the robot is operating normally. In the event of an emergency, such as when the robot needs to quickly avoid obstacles and the motion drive system urgently needs additional energy, the system can call on redundant energy to ensure that the robot responds in a timely manner and avoid failures. In the self-recovery mechanism, when there is an abnormality in the energy supply, such as the power of solar cells drops due to cloud cover, causing low-priority components to shut down, after light is restored, the system can restart high-priority components first, and then gradually restore power to low-priority components. During the recovery process, the system can continuously monitor and evaluate the status of components. If a fault occurs, the information will be recorded and processed, such as isolating the faulty component or reducing the robot's working mode to ensure stable system operation.

[0049] By synergizing maximum power point tracking technology with priority allocation, combined with energy redundancy and self-recovery mechanisms, the intelligent energy management system can achieve efficient scheduling of solar energy and battery energy, accurately optimize the energy supply ratio, significantly improve energy utilization efficiency, effectively extend the robot's endurance, and achieve efficient switching between solar energy and batteries and reasonable energy distribution.

[0050] It should be noted that this embodiment may also be an improvement based on the second embodiment and / or the third embodiment.

[0051] It is not difficult to find that in the embodiment of the present application, the intelligent energy management system integrates the maximum power point tracking technology and the energy allocation priority setting function. The maximum power point tracking technology can monitor the output power of the solar cell in real time. By dynamically adjusting the operating voltage and current, the cell can always run stably at the maximum power output state, greatly improving the energy conversion efficiency, and effectively alleviating the endurance problem caused by the insufficient energy density of traditional batteries. The energy allocation priority setting function can intelligently allocate electrical energy based on the importance and energy consumption characteristics of each component of the robot (such as the main control system, motion drive system, sensor, etc.). When the power is sufficient, the system gives priority to ensuring the stable operation of key components such as the main control system, and the remaining energy is then distributed to other components in turn, and automatically charges the battery for energy storage; when the power is insufficient, the power supply of low-priority components can be reduced in time, giving priority to ensuring the operation of the basic functions of the robot, and avoiding overall failure due to energy shortage. The two complement each other, not only improving energy utilization efficiency and robot endurance, but also enhancing the stability and reliability of system operation, ensuring that humanoid robots can continue to operate efficiently in complex environments.

[0052] Fifth embodiment

[0053] The fifth embodiment of the present application relates to a solar energy utilization device. The fifth embodiment is an improvement on the first embodiment. Specifically, in this embodiment, the outer shell structure is made of a lightweight, high-strength composite material, and a heat conduction channel is provided inside the outer shell to conduct heat.

[0054] Specifically, the solar shell of the humanoid robot can be made of lightweight, high-strength composite materials. With its light weight and high strength, this material can not only withstand collisions and external impacts, ensuring the shell is strong and durable, but also reduce the overall weight of the robot, reduce operating energy consumption, and improve mobility. In terms of structural design, the shell is bonded and fixed to the flexible solar cell through reserved slots to ensure that the cell fits firmly. At the same time, a heat conduction channel can be provided inside the shell, using high thermal conductivity materials such as metal heat pipes and thermally conductive silicone to quickly conduct the heat generated by flexible solar cells, intelligent energy management systems and other components during operation, avoid heat accumulation, and create a stable operating temperature environment for internal components, thereby extending the service life of the equipment and ensuring long-term and efficient operation of the robot.

[0055] For example, in the specific application of composite materials, carbon fiber composite materials, aramid fiber composite materials, aluminum alloy composite materials, etc. can be used. Carbon fiber composite materials are composed of carbon fiber and resin matrix, among which carbon fiber has a tensile strength of over 3500MPa and a density of only 1.7-2.0g / cm 3 The composite material has excellent specific strength and is suitable for making large-area flat parts such as the back. It can support solar cells and withstand external impact without significantly increasing weight, which helps improve endurance and sports performance. The strength of aramid fiber composite materials can reach 5-6 times that of steel wire, and the modulus is 2-3 times that of steel wire or glass fiber. The density is about 1.44g / cm 3 The composite material made of it is suitable for joint shells, which can withstand the stress generated by frequent activities, while reducing the weight of the joints and enhancing the flexibility of robot movements; aluminum alloy-based composite materials use aluminum alloy as the matrix, and after adding ceramic particles, short fibers and other reinforcement phases, while maintaining the low density of aluminum alloy (about 2.7g / cm 3 ), it can significantly improve the strength, hardness and wear resistance, and is suitable for use in parts that require machining and heat dissipation, such as the legs. It can not only meet processing requirements and assist in battery heat dissipation, but also resist collisions and maintain structural stability.

[0056] Optionally, in some embodiments, a heat dissipation channel may be provided inside the housing, and the heat dissipation channel is used to discharge heat generated inside the housing.

[0057] Specifically, the efficient heat dissipation channel set inside the modular shell is mainly used to promptly discharge the heat inside the shell to ensure the stable operation of the device. When the robot is running, internal components such as the intelligent energy management system and the motor of the dynamic angle adjustment mechanism will continue to generate heat. If the heat cannot be dissipated in time, it will affect the performance of the components and even cause failures. The heat dissipation channel can quickly transfer the internal heat to the channel through a reasonable air duct design, combined with high-efficiency thermal conductive materials such as thermal conductive silicone and heat pipes. At the same time, the built-in micro fan performs an active heat dissipation method of forced convection, accelerating the exchange of heat with the external environment and ensuring that the inside of the shell maintains a suitable operating temperature. This design can not only extend the service life of core components such as flexible solar cells, but also improve system reliability and provide a strong guarantee for the efficient operation of the cells.

[0058] Understandably, most existing designs fail to integrate efficient heat dissipation solutions, resulting in the inability to dissipate the heat generated by the solar cells during operation. Heat accumulation not only reduces the energy conversion efficiency of the cells but also shortens their storage lifespan. In this embodiment, by providing heat dissipation channels within the housing, this heat dissipation challenge can be effectively addressed.

[0059] Optionally, in some embodiments, the solar housing may be connected to the robot main control system via a standardized interface to achieve real-time transmission and remote monitoring of energy status data.

[0060] For example, the solar enclosure can be connected to the robot's main control system via a standardized interface, enabling remote monitoring and intelligent scheduling of the robot's energy system. Once connected, the solar enclosure can stably transmit key data to the main control system in real time, including the power generated by the flexible solar cells, remaining battery charge, and the operating status of the intelligent energy management system. The main control system integrates and analyzes this data, providing a local visual display of the robot's energy status and synchronizing it with a remote monitoring terminal via the network.

[0061] For example, users can remotely monitor the robot's energy usage through a mobile app or desktop management platform, promptly identifying anomalies and diagnosing faults. Furthermore, energy management parameters can be remotely adjusted for efficient control of the energy system. This connectivity not only improves operational convenience but also enhances system reliability.

[0062] For example, to enable efficient and secure interaction between the app and the robot's main control system, the system is designed from three perspectives: communication infrastructure, security protection, and functional linkage. For communication, the lightweight MQTT protocol can be used. The app subscribes to messages published by the robot's main control system regarding topics such as energy and operating status, and the main control system pushes data regularly. Data can be encapsulated in JSON format, with data such as energy status and operating status encoded and decoded according to standard formats. Network connectivity supports Wi-Fi and 4G / 5G switching, enabling data exchange between the app and the main control system in both indoor and outdoor scenarios. Token-based authentication can be used. After the app logs in and obtains a token, the main control system verifies its validity during communication. Data encryption utilizes the TLS / SSL protocol to ensure data transmission security. Access control sets different permissions for general users and administrators, and the main control system processes requests based on permissions to prevent unauthorized access. For energy scheduling, button commands on the app can control the main control system to adjust energy management strategies. For operating status monitoring, the main control system publishes data, and the app can display robot operating information in real time. When setting parameters, parameter modification commands sent by the app can enable the main control system to update configurations and optimize robot performance.

[0063] Optionally, in some embodiments, a nano-scale anti-fouling and waterproof coating is provided on the surface of the shell.

[0064] For example, by covering the surface of the shell with a nano-scale antifouling and waterproof coating, a dense protective barrier is formed on the surface of the shell with the help of the special microstructure and surface chemical properties of nanomaterials. The barrier has super-amphiphobic or super-amphiphobic properties. From a waterproofing perspective, the super-hydrophobic property of the nano-scale antifouling and waterproof coating can make water droplets roll down in a spherical shape on the surface of the coating, making it difficult to adhere. Even in rainy or humid environments, rainwater can be quickly drained away to prevent residual water stains from affecting the light transmittance of solar cells. In terms of antifouling, superoleophobic and low surface energy properties effectively resist the adhesion of pollutants such as dust and oil. In daily use, slight vibrations or wind can remove surface stains, greatly reducing the frequency of manual cleaning. In addition, the coating also has good wear resistance and chemical stability, which not only keeps the appearance of the shell clean, but also extends the service life of flexible solar cells, ensuring that humanoid robots always maintain efficient energy conversion performance in complex outdoor environments and significantly improving environmental adaptability.

[0065] It should be noted that this embodiment may also be an improvement based on any one or more of the second to fourth embodiments.

[0066] It is not difficult to find that in the embodiment of the present application, the shell structure is made of lightweight, high-strength composite materials and has built-in heat conduction channels. Lightweight, high-strength composite materials, with their high specific strength characteristics, can significantly reduce the overall weight of the robot, reduce operating energy consumption, and improve movement flexibility and endurance while ensuring that the shell is strong and durable and resistant to collisions and impacts; and the heat conduction channels set inside the shell can quickly capture the heat generated by components such as flexible solar cells and intelligent energy management systems during operation, and quickly conduct it to the surface of the shell for discharge, effectively avoiding heat accumulation inside. This not only creates a stable operating temperature environment for internal components and extends the service life of the equipment, but also ensures that the solar cells are always in an efficient energy conversion state, ensuring that the humanoid robot always maintains good performance during long-term operation and can calmly cope with various complex work scenarios.

[0067] Sixth embodiment

[0068] The sixth embodiment of the present application relates to a solar energy utilization device. The sixth embodiment is an improvement on the first embodiment, and the specific improvement is that: in this embodiment, the flexible solar cells are distributed in a preset light-receiving area.

[0069] Optionally, in some embodiments, the preset light-receiving area includes at least one of the following: the head, back and limbs of the robot.

[0070] Specifically, the flexible solar cells can be arranged in preset light-receiving areas such as the robot's head, back, and limbs based on the light reception conditions and the robot's structural characteristics to maximize the light-receiving area. The robot's head is positioned higher, effectively reducing obstruction from surrounding objects and facilitating the reception of direct sunlight; the back is large and flat, making it suitable for laying solar cells over a large area, significantly increasing the total power generation; and the limbs can dynamically adjust their orientation during the robot's movement to capture light from different angles. By evenly distributing solar cells in these key areas and fully utilizing the robot's three-dimensional space, the humanoid robot can maximize its light-receiving area whether stationary or in motion, achieving multi-angle solar energy absorption and significantly improving energy acquisition efficiency. This can provide stable power support for the robot's long-term outdoor operations.

[0071] Optionally, in some embodiments, the modular design of the housing supports disassembly and replacement.

[0072] Specifically, the housing adopts a modular design, disassembling the overall structure into multiple independent and standardized unit modules. Each module is firmly connected and fixed through interfaces of uniform specifications (such as clips, slots, quick-connect bolts, etc.). This design greatly improves the flexibility and ease of use of the housing. In actual application, when a module degrades in performance due to long-term use, is damaged by external forces, or needs to be upgraded to adapt to new application scenarios, there is no need to replace the entire housing. With the help of simple tools, the faulty or old module can be quickly removed and replaced with a new module. This feature can not only significantly reduce repair costs and maintenance time, but also support users to flexibly meet diverse usage needs by replacing modules with different functional characteristics (such as battery modules with higher photoelectric conversion efficiency and housing modules with enhanced protection), thereby effectively improving the environmental adaptability and service life of the humanoid robot, and providing a solid guarantee for the long-term stable operation of the equipment. The advantages of quick disassembly and replacement brought by the modular design can further enhance the flexibility and scalability of the device, making the device more adaptable in complex and changing application scenarios.

[0073] It should be noted that this embodiment may also be an improvement based on any one or more of the second to fifth embodiments.

[0074] It is not difficult to find that in the embodiment of the present application, flexible solar cells are distributed in preset light-receiving areas such as the robot's head, back, and limbs. The robot's head is located at a higher position, which can reduce obstruction by surrounding objects and facilitate the reception of direct light; the back has a large area and a flat surface, which is suitable for laying solar cells over a large area, which can effectively increase the total power generation; the limbs can dynamically adjust the direction during the robot's movement to capture light from different angles. By rationally arranging these key parts, the robot's three-dimensional space can be fully utilized. Whether it is stationary or in motion, multi-angle and all-round solar energy absorption can be achieved, maximizing the lighting area, significantly improving energy acquisition efficiency, and providing stable and sufficient power support for the robot's long-term outdoor operation, effectively alleviating the pressure on battery life.
