Description

Technical Field

[0001] This invention relates to the field of personal safety protective equipment and smart wearable devices, and particularly to a smart protective equipment system and its control method for two-wheeled riders. It is especially suitable for two-wheeled vehicle drivers such as food delivery riders and motorcyclists. The system integrates related technologies such as helmets, personal temperature-controlled clothing, and solar-powered storage devices. Background Technology

[0002] With the continued growth of the on-demand delivery industry and the demand for two-wheeled transportation, the rider population, represented by food delivery riders, is constantly expanding. Riders often face multiple challenges, including high safety risks, high work intensity, and poor environmental adaptability, as they operate for extended periods in complex road environments. Currently, leading companies such as Meituan and Ele.me have begun promoting smart helmet products. As of June 2025, Meituan's cumulative deployment of smart helmets has exceeded 1 million units.

[0003] Existing technologies for smart equipment targeting the aforementioned rider group have the following main shortcomings:

[0004] (1) Fragmented functions and lack of system integration: Existing technologies mainly focus on improving single helmet functions. For example, patent CN119586829A discloses a smart helmet for food delivery riders, which controls the answering or hanging up of mobile phones through Bluetooth sensors and jaw movement; some smart helmets have functions such as voice interaction, navigation broadcast and collision detection. However, existing technologies have not yet provided a complete solution that systematically integrates helmet, body protection, temperature control and power supply.

[0005] (2) Insufficient temperature control: Riders need to work for long periods of time in high summer temperatures and low winter temperatures. Traditional helmets mostly use passive ventilation structures, which have limited cooling effects; air-cooled helmets guide airflow directly to the head through a fan, but prolonged direct airflow can easily cause head discomfort and insufficient cooling depth. Existing air-conditioned clothing mainly relies on ice packs for cooling or fan ventilation. Ice packs have limited cooling time and cannot accurately control the temperature, while simple fan ventilation has limited cooling effect in high temperatures. Patent CN119606099A proposes a semiconductor duct air-cooled helmet, but its power supply is integrated into the helmet, increasing the helmet's weight and resulting in poor comfort during long-term wear.

[0006] (3) Limited safety protection functions: The collision detection function of existing smart helmets mainly focuses on fall detection and automatic distress call, but does not integrate airbag protection technology into rider body protection equipment. Patent CN120694462A proposes a driving protection device with airbags on the helmet, but the head airbag protection range is limited and cannot provide cushioning protection for the rider's torso.

[0007] (4) Limited Lens Function: Most existing helmet lenses are manually switchable double-layer lenses or lenses with fixed shading. Riders need to operate them manually when entering or exiting tunnels, encountering strong light, or riding at night, which distracts their attention and poses safety hazards. In addition, the lenses are prone to fogging when there are large temperature differences. Traditional anti-fog films or manual wiping cannot fundamentally solve the problem. The safety risks caused by fog obstructing vision during winter riding are particularly prominent.

[0008] (5) Power supply and battery life bottleneck: The battery life of intelligent equipment is a key bottleneck restricting the richness of its functions. Existing products integrate the battery inside the helmet, which increases the weight of wearing it and limits the space for functional expansion. Although some patents involve solar power supply for helmets, the power generation area is limited and it is difficult to support the long-term operation of high-power temperature control equipment.

[0009] (6) Separation of storage and equipment: The trunk of the existing two-wheeled delivery vehicle is only used as an independent storage container and does not form a functional linkage with the rider's equipment. It occupies the vehicle space but does not directly improve the rider's working experience. Summary of the Invention

[0010] The purpose of this invention is to address the technical problems existing in the background art. To this end, it provides an intelligent protective equipment system and its control method for two-wheeled riders. This system, through the organic combination of an intelligent helmet, intelligent temperature-controlled protective clothing, and a multi-functional power-powered storage compartment, achieves an integrated solution encompassing intelligent navigation scheduling, environmentally adaptive field of vision adjustment, active whole-body temperature control, airbag safety protection, centralized power supply, automatic lens defogging, and basic storage functions. While ensuring rider safety and comfort, it also meets the needs of goods transportation, comprehensively improving riders' travel safety and work comfort.

[0011] To achieve the above objectives, the technical solution adopted by the present invention is as follows: (I) System Overall Architecture: The intelligent protective equipment system provided by this invention comprises three core modules: an intelligent helmet, an intelligent temperature-controlled protective suit, and a multi-functional power supply backup box. The multi-functional power supply backup box serves as the system's energy center and airflow power center. It is detachably connected to the intelligent helmet and intelligent temperature-controlled protective suit via quick-connect air and electrical interfaces, respectively, enabling centralized power supply and centralized air generation, effectively reducing the weight of the helmet and protective suit.

[0012] (II) Smart Helmet Module: The smart helmet includes a helmet shell, as well as a detachable positioning and navigation module, a Bluetooth communication module, an adaptive smart lens module, and a helmet air-cooling air conditioning module, all mounted on the helmet shell.

[0013] (1) Detachable positioning and navigation module: It adopts a modular design and can be installed according to the rider's needs. The module integrates a GPS / BeiDou dual-mode positioning unit, an inertial navigation auxiliary unit and a mobile communication unit, and interacts with a remote server (such as a food delivery platform) in real time through a wireless communication network. The module has the following functions: ① Intelligent dispatch - In the food delivery scenario, it receives the platform's order information and broadcasts it via voice; ② Precise route prompts - It provides high-precision navigation and voice guidance for complex road sections (such as old residential areas, narrow alleys, and areas without clear house numbers). The inertial navigation auxiliary unit can maintain positioning continuity when the GPS signal is weak; ③ Accidental upload - When it is detected that the rider stays in an abnormal area for more than the set time, or when an airbag trigger signal is received, the location information and event type are automatically uploaded to the remote server or the preset emergency contact.

[0014] (2) Bluetooth communication module: integrated on both sides of the helmet, it connects to the rider's mobile phone via Bluetooth to enable hands-free calling and voice navigation broadcast. Riders do not need to wear additional in-ear headphones, reducing ear pressure and discomfort.

[0015] (3) Adaptive Intelligent Lens Module: This module includes a lens substrate, a photoelectric sensor array, an electrochromic layer, a drive circuit, and a defogging heating unit. The photoelectric sensor array detects ambient light intensity and light type (such as strong sunlight, tunnel darkness, and oncoming high beams at night) in real time, while integrating a temperature and humidity sensor to monitor the risk of fogging on the inside of the lens. The drive circuit applies a corresponding driving voltage to the electrochromic layer based on the detection results, enabling the lens to automatically and seamlessly switch between transparent mode, sun protection mode, and night vision enhancement mode. When the temperature and humidity sensor detects that the temperature on the inside of the lens is close to the dew point or the relative humidity exceeds a preset threshold, the defogging heating unit automatically starts, using the temperature-controlled airflow introduced by the helmet's air-cooled air conditioning module or the built-in micro-heating element to uniformly heat the lens, eliminating or preventing fog condensation. This design allows riders to maintain a clear and fog-free field of vision without manual operation, significantly improving riding safety.

[0016] (4) Helmet air-cooled air conditioning module: This includes an airflow distribution duct on the inner surface of the helmet shell, an air intake interface connected to the airflow distribution duct, and a temperature sensor. The airflow distribution duct adopts a multi-channel structure design to evenly guide cold / hot airflow to the rider's head and forehead area, and can provide temperature-regulating airflow for the aforementioned defogging and heating units. The air intake interface is connected to the high-pressure air pump outlet in the trunk via a quick-connect air circuit. The helmet itself does not have a cooling / heating device or battery, which greatly reduces the load on the head.

[0017] (III) Intelligent Temperature Control Protective Clothing Module: The intelligent temperature-controlled protective clothing includes the garment body, a semiconductor cooling / heating unit array set on the inner surface of the garment body, a temperature sensor, a control module, and an airbag protection module.

[0018] (1) Temperature control scheme design: Two versions are available. Version 1 is an independent working version. The garment body has a built-in semiconductor cooling / heating unit array and a small-capacity auxiliary battery. It uses a semiconductor cooling chip to achieve active cooling or heating using the Peltier effect. The cooling effect is more significant when the outside temperature is higher under sunlight. Riders can wear it directly without connecting to the air circuit in the trunk. Version 2 is an intelligent linkage version. Based on Version 1, it adds a quick-connect air circuit interface and a wireless communication module that are linked to the trunk. The control module receives the target temperature command sent by the trunk main control unit wirelessly, coordinates and regulates the working current of the semiconductor cooling / heating unit, and introduces temperature-controlled airflow through the quick-connect air circuit to achieve uniform body temperature regulation.

[0019] (2) Airbag Protection Module: This module includes an inflatable airbag folded and stored within the inner layer of the garment, a compressed air cylinder, an electronically controlled trigger valve, and an inertial measurement unit (IMU). The IMU collects the rider's posture acceleration and angular velocity data in real time. The control module runs a collision detection algorithm. When the rate of change of acceleration or angular velocity exceeds a preset collision / rollover threshold, a trigger signal is output to the electronically controlled trigger valve, and the high-pressure gas in the compressed air cylinder is released instantaneously, allowing the airbag to inflate and deploy within a preset time (preferably 50-100ms). After deployment, the airbag covers the rider's chest, back, and shoulders, effectively buffering the impact force and reducing injuries caused by the impact. Preferably, the helmet and the temperature-controlled protective clothing share IMU data, so that the airbag can be triggered when either detects an abnormal state, improving detection reliability and response speed.

[0020] (iv) Multifunctional power supply trunk module: The multi-functional power supply trunk includes a trunk body, flexible solar panels laid on the outer surface of the trunk body, an energy storage battery pack installed inside the trunk body, a high-pressure air pump, a semiconductor cooling / heating device, and a main control unit.

[0021] (1) Storage and equipment partition design: The internal space of the box is divided into two layers or two zones by partitions. The storage zone is used to place takeaway food boxes, parcels or personal luggage, and its volume is comparable to that of traditional delivery boxes. The equipment zone is independently enclosed and used to install power supply and airflow supply components to ensure that electrical equipment is isolated from goods and to ensure safety.

[0022] (2) Solar power supply system: Flexible solar panels are laid on the outer surface of the top of the trunk to make full use of the sunlight resources during the daytime operation of the food delivery vehicle, converting solar energy into electrical energy and storing it in the energy storage battery pack. The main control unit has intelligent power management function, which dynamically allocates power according to the real-time power consumption of each module and the remaining battery power.

[0023] (3) Centralized airflow supply system: A high-pressure air pump generates high-pressure airflow, which is then temperature-regulated by a semiconductor cooling / heating device before being delivered to the helmet-cooled air conditioning module of the smart helmet and the internal airflow channel of the smart temperature-controlled protective suit via quick-connect air paths. The semiconductor cooling / heating device adopts a reversible working mode design, switching between cooling and heating modes by changing the direction of the working current. The main control unit independently controls the temperature and flow rate of each output airflow based on the temperature data fed back from the helmet and protective suit, achieving precise temperature control of the helmet and body in separate zones.

[0024] (4) Weight reduction design advantages: The battery pack, high-pressure air pump and cooling / heating device are all concentrated in the trunk. The smart helmet only retains the airflow distribution duct, and the temperature control protective clothing only retains the semiconductor cooling / heating unit array (version one) or airflow interface (version two), which greatly reduces the burden on the rider's head and body and significantly improves the wearing comfort during long-term operation.

[0025] A control method for an intelligent protective equipment system for two-wheeled riders, comprising: After the system is powered on, the main control unit executes a self-test program to confirm that all modules are communicating normally, the battery is fully charged, and the air pressure is normal. The detachable positioning and navigation module receives scheduling and navigation information from a remote server, broadcasts prompts via Bluetooth communication, and automatically plans the optimal route. When the rider enters an area with weak GPS signal, the inertial navigation assist unit automatically starts and continuously tracks the real-time location; The adaptive smart lens module automatically switches lens modes according to changes in ambient light and monitors the temperature and humidity inside the lens in real time, automatically activating the defogging function when there is a risk of fogging. The helmet's air-cooled air conditioning module and the intelligent temperature-controlled protective suit continuously feed temperature data back to the main control unit. The main control unit dynamically adjusts the airflow temperature and flow rate according to the set target temperature to maintain a comfortable temperature for the rider's head and body. When a rider encounters a sudden collision or rollover accident: the inertial measurement unit detects that the rate of change of acceleration and angular velocity exceeds the threshold, the control module completes the event determination and outputs a trigger signal within 10ms, the electronic trigger valve is turned on, and the inflatable airbag is inflated and deployed within 80ms to form a protective buffer layer; at the same time, the automatic accident reporting unit sends the accident location and event type to the remote server or preset emergency contact via the mobile communication module to facilitate timely dispatch of rescue. After the trip, the rider disconnects the quick-connect air circuit and electrical interface, and the system enters standby mode; the solar panel continuously recharges the energy storage battery pack during the day, storing energy for the next trip.

[0026] Compared with the prior art, the present invention has the following technical effects: (1) System integration: For the first time, intelligent navigation scheduling, environmental adaptive field of vision adjustment, whole body active temperature control, airbag safety protection, centralized power supply, automatic lens defogging and basic storage functions are integrated into an integrated system, filling the gap in system-level solutions in the field of rider intelligent protective equipment.

[0027] (2) Significantly improved safety performance: The adaptive smart lens has automatic mode switching and automatic defogging function, so that the rider can always maintain the best vision without fog; the airbag protection module uses IMU collision detection technology to complete the airbag deployment within 50-100ms, effectively buffering the impact force; the accident upload function ensures timely rescue in emergency situations.

[0028] (3) Improved travel and work efficiency: The detachable positioning and navigation module supports accurate navigation and intelligent order dispatch in complex road sections, and the Bluetooth communication module enables hands-free calling, reducing the time riders spend operating their mobile phones, thus comprehensively improving travel and work efficiency.

[0029] (4) All-weather comfort experience: The helmet's air-cooled air conditioner and temperature-controlled protective clothing work together to adapt to a wide temperature range of -10℃ to 40℃, completely solving the industry's pain points of hot summer and cold winter, and effectively preventing the lenses from fogging up.

[0030] (5) Lightweight design: The battery, air pump and cooling / heating device are centrally located in the trunk and powered by quick-connect air and circuit interfaces. The weight of the smart helmet and temperature-controlled protective clothing is greatly reduced, making them suitable for long-term wear.

[0031] (6) Green and energy-saving: Solar panels use sunlight during the day to supplement charging, reducing the frequency of battery replacement or mains charging, extending the system's battery life, and conforming to the green and low-carbon concept.

[0032] (7) Storage function integration: While carrying the core functions of power supply and temperature control for intelligent equipment, the trunk retains the storage capacity of traditional storage boxes without taking up additional vehicle space, thus achieving multiple uses for one box.

[0037] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] System overall structure and connection relationships: Reference Figure 1-6As shown, this embodiment provides an intelligent protective equipment system for two-wheeled riders, including an intelligent helmet 100, an intelligent temperature-controlled protective suit 200, and a multi-functional power supply trunk 300.

[0039] The smart helmet 100 and smart temperature-controlled protective suit 200 are detachably connected to the multi-functional power supply trunk 300 via quick-connect air inlet 400 and electrical interface 500, respectively. When starting work, the rider puts on the smart helmet 100 and the smart temperature-controlled protective suit 200 around the torso. The plug of the quick-connect air inlet 400 is inserted into the air intake port on the side rear of the smart helmet 100 and the air intake port on the back of the smart temperature-controlled protective suit 200, respectively. The plug of the electrical interface 500 is inserted into the corresponding charging port. The multi-functional power supply trunk 300 is fixedly installed on the rear rack of the vehicle. The upper storage area is used to store takeout containers or luggage, while the lower equipment area provides all the power and airflow for the system.

[0040] The specific structure of a smart helmet: Reference Figure 2 The smart helmet 100 includes a helmet shell 101, which is made of carbon fiber composite material and has good impact resistance and lightweight characteristics.

[0041] Positioning and Navigation Module: The detachable positioning and navigation module 102 is located in the rear recess of the helmet shell 101, using a snap-on quick-install structure, allowing riders to install or remove it as needed. The module integrates a GPS / BeiDou dual-mode positioning chip (Ublox ZED-F9P or equivalent), a 6-axis IMU inertial measurement chip (BMI160), a 4G / 5G mobile communication module, and an MCU main control chip. The module maintains a continuous connection with a remote server (such as a food delivery platform) via a mobile communication network, receiving real-time dispatch and navigation information. When the rider enters a residential area with weak GPS signal or a narrow alley, the inertial navigation assistance unit uses the acceleration and angular velocity data collected by the IMU to perform dead reckoning based on the nearest valid GPS positioning point, maintaining continuous position estimation and ensuring uninterrupted navigation. When the module detects that the rider has stayed in an abnormal area outside the delivery destination for more than 5 minutes, or receives a signal triggered by the airbag protection module 210, the automatic event reporting unit uploads the current location coordinates and event type code to the remote server or a preset emergency contact via the mobile communication module.

[0042] Bluetooth Communication Module: The Bluetooth communication module 103 includes two Bluetooth headset units located on the left and right sides of the helmet shell 101, near the ears. Each Bluetooth headset unit includes a speaker, microphone, Bluetooth SoC chip (such as Qualcomm QCC3020), and touch buttons. Riders can answer or hang up calls by lightly touching either side of the touch button, and the call audio is played through the Bluetooth headset without needing to hold the phone close to the ear.

[0043] Adaptive Smart Lens Module: The adaptive smart lens module 104 includes a lens substrate 1041, a photoelectric sensor array 1042, an electrochromic layer 1043, a driving circuit 1044, and a defogging heating unit 1045. The lens substrate 1041 is made of PC (polycarbonate) material, and its surface is covered with an electrochromic layer 1043, which preferably uses a WO3 / NiO multilayer electrochromic material system. The photoelectric sensor array 1042 includes a visible light sensor, an infrared sensor, and an ultraviolet sensor, and is mounted above the lens substrate 1041. It also integrates a temperature and humidity sensor for monitoring the temperature and humidity inside the lens. The defogging heating unit 1045 can be implemented using a miniature heating wire surrounding the edge of the lens or an inner nozzle connected to the airflow distribution duct. When the photoelectric sensor array 1042 detects ambient light intensity exceeding 50,000 lux (strong sunlight conditions), the drive circuit 1044 applies a 2.5V DC voltage to the electrochromic layer 1043, switching the lens to sun protection mode, reducing light transmittance to approximately 20%. When the ambient light intensity is detected to be below 100 lux (nighttime or tunnel conditions) and oncoming vehicle high beams are detected, the lens switches to night vision enhancement mode, selectively attenuating specific wavelengths of strong light; under other conditions, the lens remains in transparent mode. The mode switching time is no more than 2 seconds. When the temperature and humidity sensor detects that the relative humidity inside the lens exceeds 80% or the temperature difference between the lens and the dew point is less than 2°C, the drive circuit 1044 activates the defogging heating unit 1045, using a temperature-controlled gentle airflow or micro-heating wire to uniformly heat the lens, making the lens temperature slightly higher than the dew point, thereby completely eliminating or preventing fog condensation. The defogging function can operate in parallel with other modes without interference.

[0044] Helmet Air-Cooled Air Conditioning Module: The helmet air-cooled air conditioning module 105 includes an airflow distribution duct 1051, an air intake interface 1052, and a temperature sensor 1053, all disposed on the inner surface of the helmet shell 101. The airflow distribution duct 1051 adopts a multi-channel structure to evenly distribute the incoming airflow to the rider's top of the head, forehead, and temples, and can also provide temperature-regulating airflow for the aforementioned defogging and heating unit. The air intake interface 1052 is a self-sealing quick-connect connector located at the lower rear of the helmet shell 101, which automatically closes when no air passage is connected. The temperature sensor 1053 is installed in the helmet liner close to the rider's forehead, providing real-time feedback of head temperature data to the main control unit 306.

[0045] The specific structure of intelligent temperature-controlled protective clothing: Reference Figure 3 The intelligent temperature-controlled protective suit 200 includes the garment body 201, which is made of breathable and waterproof fabric and is available in vest or long-sleeved styles.

[0046] Temperature control system: Semiconductor cooling / heating unit array 202 is distributed on the surface of the front, back, and waist areas of the garment body 201. Each unit includes a semiconductor cooling chip (preferably 30×30mm, model TEC1-12706), with a copper heat-conducting plate attached to one side of the cooling chip in contact with the inner surface of the garment, and heat dissipation fins attached to the other side. In the stand-alone version (version one), the semiconductor cooling / heating unit array 202 is powered by a small-capacity lithium battery pack built into the garment body 201. The control module 204 performs PID closed-loop control based on feedback from the temperature sensor 203 to maintain the internal temperature of the garment within the set comfort range. In the intelligent linkage version (version two), the garment body 201 is further equipped with a quick-connect air interface 207, which connects to the multi-functional power supply trunk 300 via a quick-connect air passage 400. The control module 204 communicates with the main control unit 306 via Bluetooth Low Energy, receives target temperature commands, and coordinates and regulates the working status of the semiconductor cooling / heating unit array 202 and the introduced airflow.

[0047] Airbag Protection Module: The airbag protection module 205 includes an inflatable airbag 2051, a compressed air cylinder 2052, an electrically controlled trigger valve 2053, and an inertial measurement unit 2054. The inflatable airbag 2051 is made of high-toughness nylon coated TPU material, folded and stored in the interlayer of the garment body 201, covering the chest, back, and shoulder areas. The compressed air cylinder 2052 has a capacity of approximately 20-30g CO2 and a pre-inflation pressure of approximately 60 bar. The inertial measurement unit 2054 uses a 6-axis IMU chip, installed at the back of the garment body 201, and collects acceleration and angular velocity data in real time at a sampling rate of 100Hz. The control module 204 runs a threshold-based collision detection algorithm: the composite acceleration threshold a_th = 4g and the angular velocity change rate threshold ω_th = 300° / s² are set; when the composite acceleration exceeds a_th and the angular velocity change rate exceeds ω_th, it is determined to be a collision or rollover event, and a 5V trigger pulse is immediately output to the electronically controlled trigger valve 2053, the high-pressure gas in the compressed gas cylinder 2052 is released instantly, and the inflatable airbag 2051 completes inflation and deployment within about 80ms.

[0048] Furthermore, the detachable positioning and navigation module 102 of the smart helmet 100 also integrates an IMU sensor. The control module 204 communicates with the positioning and navigation module 102 via Bluetooth to share IMU data. When either the helmet IMU or the protective suit IMU detects an abnormal state, the airbag can be deployed, achieving dual redundancy detection and improving the reliability of protection in extreme situations.

[0049] The specific structure of the multi-functional power supply trunk: Reference Figure 4The multi-functional power supply trunk 300 includes a trunk body 301, which is made of an aluminum alloy frame combined with an ABS plastic shell. The internal space of the trunk body 301 is divided into an upper storage area 301a and a lower equipment area 301b by a horizontal partition 307. The inner wall of the storage area 301a is equipped with an insulation layer and a non-slip mat, and is used to store takeout containers, packages, or personal luggage, with a volume of approximately 40-60 liters. The equipment area 301b is used to install power supply and airflow supply components, and is isolated from the storage area 301a to ensure electrical safety.

[0050] Solar power supply system: Flexible solar panels 302 are laid on the top outer surface of the enclosure 301, with an area preferably of 0.3-0.5 square meters. They utilize monocrystalline silicon flexible photovoltaic modules with a photoelectric conversion efficiency of no less than 20%. Under good sunlight conditions, the output power of the solar panels 302 is approximately 50-80W. The energy storage battery pack 303 uses lithium iron phosphate batteries, with a capacity preferably of 200-300Wh, and is located at the bottom of the equipment area of ​​the enclosure 301. The main control unit 306 has MPPT (maximum power point tracking) solar charging management functions and simultaneously monitors the charge status and health status of the energy storage battery pack 303.

[0051] Centralized airflow supply system: The high-pressure air pump 304 is a miniature oil-free scroll pump with an operating voltage of 24V and an adjustable output pressure of 0.03-0.1MPa, installed on one side of the equipment area in the housing 301. The semiconductor cooling / heating device 305 includes two sets of semiconductor cooling chips (TEC1-12710), corresponding to the helmet's output air path and the protective suit's output air path, respectively. Each set of cooling chips switches the direction of the operating current through an H-bridge drive circuit, thereby switching between cooling and heating modes. The heat dissipation side of the semiconductor cooling / heating device 305 dissipates / absorbs heat to the outside of the housing through an aluminum heat sink and an axial fan.

[0052] The main control unit 306 is designed based on the STM32 series microcontroller and integrates a Bluetooth 5.0 wireless communication module. The main control unit 306 receives temperature data from the smart helmet 100 and the smart temperature-controlled protective suit 200 via Bluetooth. Based on the user-set target temperature (e.g., 22℃ for the helmet and 25℃ for the protective suit), it uses a PID algorithm to control the speed of the high-pressure air pump 304 and the operating current of the semiconductor cooling / heating device 305, achieving independent temperature control of the two output airflows. It can also temporarily adjust the temperature and flow rate of the helmet's airflow path according to the lens defogging requirements.

[0053] Quick-connect air circuit interface: The quick-connect air circuit 400 uses a self-sealing quick-connect connector. The male end is located in the smart helmet 100 and the smart temperature-controlled protective clothing 200, and the female end is located in the multi-functional power supply backup box 300. When connecting, the male end is inserted into the female end and automatically opens the airflow. When disconnecting, both ends are automatically sealed to prevent impurities from entering the air circuit.

[0054] System workflow: Before starting their journey: Secure the multi-functional power supply trunk 300 to the rear rack of the vehicle, place the food delivery containers or luggage to be delivered into the storage area 301a and close the lid. Wear the smart helmet 100 on your head and the smart temperature-controlled protective suit 200 on your torso, and connect the quick-connect air circuit 400 and the circuit interface 500. After the system is powered on, the main control unit 306 executes a self-test program to confirm that all modules are communicating normally, the battery is fully charged, and the air circuit pressure is normal.

[0055] During the journey: The detachable positioning and navigation module 102 receives scheduling and navigation information from a remote server, broadcasts prompts via Bluetooth communication module 103, and automatically plans the optimal route. When the rider enters an area with weak GPS signal, the inertial navigation assistance unit automatically activates to continuously track the real-time location. The adaptive smart lens module 104 automatically switches lens modes according to changes in ambient light and monitors the temperature and humidity inside the lens in real time, automatically activating the defogging function when there is a risk of fogging. The helmet's air-cooled air conditioning module 105 and the smart temperature-controlled protective suit 200 continuously feed temperature data back to the main control unit 306, which dynamically adjusts the airflow temperature and flow rate according to the set target temperature to maintain a comfortable temperature for the rider's head and body.

[0056] When a rider experiences a sudden collision or rollover: the inertial measurement unit 2054 (or helmet IMU) detects that the rate of change of acceleration and angular velocity exceeds the threshold. The control module 204 completes the event determination within 10ms and outputs a trigger signal. The electronically controlled trigger valve 2053 is activated, and the inflatable airbag 2051 inflates and deploys within 80ms, forming a protective buffer layer. Simultaneously, the automatic accident reporting unit sends the accident location and event type to a remote server or a preset emergency contact via the mobile communication module, facilitating timely dispatch of rescue efforts.

[0057] After the trip: The rider disconnects the quick-connect air circuit 400 and the circuit interface 500, and the system enters standby mode. The solar panel 302 continuously recharges the energy storage battery pack 303 during the day, storing energy for the next trip.
