Description

Technical Field

[0001] This invention relates to the field of helmet technology, specifically to an intelligent protective helmet. Background Technology

[0002] With the development of modern technology, helmets, as important head protection equipment, have far exceeded the traditional scope of protection in terms of function and use. Especially in high-risk or special environments, such as construction, fire rescue, military operations, and outdoor sports, the requirements for helmet safety performance, intelligence level, and comfort are becoming increasingly higher.

[0003] Traditional helmets rely primarily on their physical structure to withstand external impacts and injuries, while modern smart protective helmets integrate various advanced sensors, communication technologies, and display technologies to achieve real-time monitoring, early warning, and information interaction regarding the head environment. For example, in some industrial or firefighting scenarios, workers may face extreme environments such as high temperatures and toxic gases, in which case traditional helmets become inadequate.

[0004] To address these issues, the industry has begun developing smart protective helmets with functions such as environmental monitoring, early warning, communication, and navigation. These helmets can monitor key indicators such as ambient temperature and harmful gas concentrations in real time, and issue timely alarms when abnormalities are detected, reminding the wearer to take necessary protective measures. Simultaneously, they can exchange data and be remotely controlled with external smart devices via wireless communication technology, improving operational efficiency and safety.

[0005] However, existing smart protective helmets still have some shortcomings in terms of power generation, alarm systems, emergency call functions, and entertainment features. For example, many helmets still rely on traditional battery power, which not only has limited battery life but also poses potential safety hazards in extreme environments. Furthermore, some helmets have limited alarm systems that are ineffective at attracting the attention of those nearby. In emergencies, wearers may be unable to send out distress signals in time, potentially missing the optimal rescue opportunity; and they lack navigation capabilities, failing to provide guidance for outdoor activities.

[0006] Therefore, a helmet with multiple intelligent protection and navigation functions has become an urgent problem to be solved. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a protective helmet that not only has basic physical protection functions, but also integrates intelligent functions such as power generation system, environmental monitoring, information display, and emergency assistance.

[0008] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: an intelligent protective helmet, including a helmet body and an inner liner disposed inside the helmet body; a power generation system is provided on the top of the helmet body, a head-up display screen is provided on the front side of the helmet body, and an adjustment knob connected to the inner liner is provided at the rear of the helmet body; and headbands are provided on both sides of the inner liner for rotatable connection.

[0009] The hat body is equipped with a controller inside; cameras are installed on the front and back sides of the hat body, and distance sensors are installed on both sides of the hat body;

[0010] A thermal imaging module is located above the head-up display screen and is electrically connected to the head-up display screen; a HUD information display module is located inside the cap and is electrically connected to the head-up display screen, projecting the received information data onto the head-up display screen;

[0011] The top of the inner side of the cap is equipped with a temperature sensor and a toxic gas sensor, and an alarm is installed on the side wall of the cap. The temperature sensor and the toxic gas sensor monitor the ambient temperature and harmful gases in real time and send the monitoring data to the controller.

[0016] Furthermore, the alarm includes a buzzer and an LED indicator. The buzzer sounds an alarm upon receiving a signal indicating abnormal temperature or gas data, and the LED indicator flashes an alarm upon receiving a signal indicating abnormal temperature or gas data.

[0017] Furthermore, the hat body is equipped with an emergency assistance module, which has a built-in wireless communication unit that sends a distress message to emergency contacts.

[0018] Furthermore, a VR / AR module is provided inside the cap, and the VR / AR module is electrically connected to the controller.

[0019] Furthermore, the navigation module is either BeiDou navigation or GPS navigation.

[0020] Furthermore, the upper part of the cap body is provided with air holes.

[0039] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "vertical", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0040] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0041] The present invention provides a smart protective helmet in further detail below with reference to the accompanying drawings.

[0042] Combined with appendix Figure 1-11 The specific implementation process of the intelligent protective helmet of the present invention is as follows:

[0043] A smart protective helmet consists of a helmet body and an inner liner. The helmet body is made of high-strength, lightweight composite material to ensure the wearer's head safety. The inner liner is located inside the helmet body and is made of soft, sweat-absorbing material to provide a comfortable wearing experience.

[0044] The hat has a power generation system at the top, a head-up display at the front, and an adjustment knob at the back that connects to the inner lining. The inner lining has straps on both sides that rotate to adjust the tightness of the fit.

[0045] The power generation system includes a micro wind turbine, a biofilm power generation module, a solar power generation module, a thermoelectric power generation module, and a vibration power generation module.

[0046] The miniature wind turbine utilizes wind power to generate electricity. It is electrically connected to the controller via waterproof and dustproof wiring, ensuring stable power transmission even in harsh environments. It can intelligently adjust the helmet's power consumption based on wind speed, ensuring long-term stable operation and reducing reliance on traditional power sources. The miniature wind turbine is compact, lightweight, and capable of generating electricity in light winds. It is environmentally friendly, renewable, and suitable for various wind speeds. It is ideal for use in open outdoor environments with suitable wind speeds, such as mountain exploration and offshore operations.

[0047] The biofilm power generation module utilizes the energy generated during the evaporation of sweat on human skin, converting it into electrical energy through bacterial biofilm to provide a continuous power supply for the helmet.

[0048] The core of the biofilm power generation module lies in a specially cultured bacterial biofilm. This biofilm is composed of microorganisms capable of generating electricity, such as electroactive bacteria like *Geobacterium sulfurreducens*. These microorganisms produce electrons during their metabolism, thereby converting chemical energy into electrical energy.

[0049] The biofilm power generation module is designed to fit snugly inside the lining of human skin to effectively harvest energy generated during the evaporation of sweat. As sweat evaporates, it carries away heat from the skin, creating minute temperature and humidity variations. The biofilm power generation module utilizes these subtle environmental changes, converting them into electricity through the metabolic activities of microorganisms.

[0050] To ensure a stable electrical connection between the biofilm power generation module and the controller without compromising the wearer's comfort, a flexible electrode design can be used. This electrode can fit snugly between the biofilm power generation module and the controller, ensuring stable power transmission.

[0051] Since the electrical energy generated by the biofilm power generation module may be relatively weak, signal amplification and rectification are required before it can be connected to the controller. This can be achieved by integrating a miniature signal amplifier and rectifier circuit into the connection section to ensure that the controller receives a stable and reliable electrical signal.

[0052] The biofilm power generation module utilizes the energy generated during the evaporation of sweat from human skin and converts it into electrical energy using bacterial biofilm technology. Simultaneously, through flexible electrode design, waterproof and dustproof treatment, and signal amplification and rectification, stable electrical connection with the controller and efficient energy conversion are ensured.

[0053] In practical applications, miniature wind turbines and biofilm power generation modules can work together to provide power for smart protective helmets. For example, when wind resources are abundant, the miniature wind turbine can serve as the primary power source, providing stable power support for the electronic equipment inside the helmet. When wind is insufficient or when the body sweats excessively, the biofilm power generation module can utilize the energy generated by sweat evaporation to power the helmet, thus ensuring that the helmet can function normally in various environments.

[0054] The solar power module is located on the outer surface of the helmet and electrically connected to the controller, using solar panels to convert solar energy into electrical energy. The solar panels typically consist of multiple photovoltaic cells that convert sunlight into direct current (DC), which then powers the electronic equipment inside the helmet. Solar power generation is environmentally friendly, renewable, requires no additional fuel, and has low maintenance costs. It is suitable for use in well-lit outdoor environments, such as construction sites and outdoor adventures.

[0055] Both the thermoelectric power generation module and the vibration power generation module are housed inside the cap and electrically connected to the controller. The thermoelectric power generation module utilizes the Seebeck effect, where a potential difference is generated across the ends of a conductor or semiconductor at different temperatures, thus converting heat energy into electrical energy. Thermoelectric panels typically consist of two semiconductor materials; when one side is heated while the other remains at a lower temperature, electricity is generated. This power generation module requires no moving parts, produces no noise or emissions, and is suitable for various temperature environments. It is ideal for use in environments with significant temperature differences, such as polar expeditions and high-temperature work environments.

[0056] The vibration-generating module utilizes the piezoelectric effect or electromagnetic induction to convert the mechanical energy generated by the wearer's head movements or environmental vibrations into electrical energy. Piezoelectric materials generate an electric charge when subjected to pressure, while electromagnetic induction produces an electric current through the relative motion of a coil and a magnet. This module requires no external power source, continuously harvests environmental energy, and is suitable for dynamic environments. It is ideal for use in situations requiring frequent head movements or significant environmental vibrations, such as cycling and outdoor sports.

[0057] The helmet is equipped with a temperature sensor and a toxic gas sensor. The temperature sensor is located near the top of the wearer's head to accurately monitor the ambient temperature. The toxic gas sensor is also positioned above the inner lining of the helmet, but at a distance to avoid interference. The toxic gas sensor uses highly sensitive electrochemical or infrared absorption principles to monitor the concentration of harmful gases in the surrounding environment in real time and transmits the data to the controller. The alarm is installed in a conspicuous location on the outside of the helmet, such as below the brim or on the side, so that the wearer and those around them can clearly hear the alarm.

[0058] How temperature and toxic gas monitoring functions are implemented:

[0059] Data Acquisition: Temperature sensors and toxic gas sensors collect ambient temperature and harmful gas concentration data in real time through their respective sensing elements.

[0060] Data transmission: The collected data is transmitted to the controller via wired or wireless means.

[0061] Data Analysis and Alarm: The controller analyzes and processes the received data. Once an abnormality in temperature or gas is detected (such as temperature exceeding the safe range or concentration of harmful gases exceeding the standard), the alarm is immediately triggered to issue an audible and visual alarm signal, which is emitted through a buzzer and LED indicator light.

[0062] In smart protective helmets, the buzzer is primarily responsible for sound alarms. When the temperature sensor or toxic gas sensor detects abnormal environmental data, the buzzer receives an abnormal signal from the controller and immediately emits a high-decibel sound to alert the wearer to potential dangers.

[0063] LED indicator lights in smart protective helmets serve as visual alarms. Similar to buzzers, when temperature or gas sensors detect abnormal environmental data, the LED indicator light receives the abnormal signal from the controller and begins to flash, providing an intuitive visual warning. Furthermore, different colors or flashing frequencies can be used to distinguish different types of alarms, providing the wearer with even more intuitive visual cues.

[0064] The helmet features an internal navigation module supporting BeiDou or GPS navigation. It connects wirelessly to external smart devices via a transceiver unit, providing precise navigation guidance. Through a wireless connection with an Arduino controller, it achieves accurate positioning and navigation, making it particularly suitable for outdoor adventures, search and rescue, and other similar scenarios. Additionally, the helmet includes an emergency call module with a built-in wireless communication unit, allowing users to send distress messages to emergency contacts.

[0065] Cameras are located on the front and back of the helmet to capture images of the surrounding environment. These cameras utilize high-definition modules to capture images of the foreground, supporting video recording and photo taking. They connect to the controller via USB, MIPI, and other interfaces for real-time image data transmission. Distance sensors are located on both sides of the helmet to detect obstacle distances. These sensors employ ultrasonic or infrared ranging technology to monitor the distance between the helmet and objects in front in real time. They connect to the controller via I2C, SPI, and other interfaces for real-time distance data transmission. The front and rear cameras, along with the side auxiliary sensors, are controlled by an Arduino controller, enabling omnidirectional, blind-spot-free environmental monitoring.

[0066] A thermal imaging module is located above the head-up display (HUD) to show the ambient temperature distribution. Utilizing an uncooled infrared thermal imager, it can penetrate smoke and darkness to display real-time images of object thermal radiation. It connects to the controller via high-speed interfaces such as LVDS and GigE Vision for real-time transmission of thermal imaging data. This integrated high-precision thermal imaging module captures ambient infrared radiation and converts it into a clear thermal image displayed on the helmet's built-in HUD. In nighttime or low-light conditions, this helps users clearly identify object outlines and temperature distribution, enhancing safety.

[0067] The HUD information display module projects received information onto the head-up display screen for easy viewing by the wearer. The head-up display screen uses micro-projection technology or a transparent OLED screen to project key information directly onto a transparent screen in front of the wearer's line of sight. It connects to the controller via high-definition interfaces such as HDMI and MIPI to achieve high-definition image transmission. The HUD information display module, integrated with the head-up display screen, is responsible for displaying navigation information, speed, distance, and other key data. It connects to the controller via an internal bus for rapid data processing and display.

[0068] The controller, acting as the "brain" of the smart protective helmet, is responsible for receiving data input from various sensors and modules, and processing and analyzing it. Based on preset algorithms and logic, the controller can make corresponding decisions and control the output of each module. For example:

[0069] When the temperature sensor detects that the ambient temperature is too high, the controller can trigger the alarm to emit an audible and visual alarm signal, which will be displayed on the HUD information display module at the same time.

[0070] When the navigation module receives new navigation instructions, the controller can calculate the optimal route and display it on the HUD information display module, while simultaneously guiding the camera and distance sensor to perform real-time monitoring and adjustments.

[0071] Through this control logic, the smart protective helmet can sense changes in the external environment in real time and respond accordingly, providing wearers with comprehensive safety protection and a convenient operating experience.

[0072] The helmet can be equipped with an optional VR / AR module that is electrically connected to the controller, integrating virtual and real elements to create a mixed reality interactive space and enrich the user experience.

[0073] The hat has vents at the top to ensure breathability when worn.

[0074] The smart helmet of this invention is specially designed for the assistance of deaf and mute people:

[0075] 1. Enhanced Perception: The helmet's camera and head-up display help deaf people better observe and understand their surroundings. This design allows deaf people to obtain external information more intuitively, improving their perception in complex environments.

[0076] 2. Emergency Assistance Function: Considering the communication difficulties that deaf and mute individuals may face in emergencies, the smart helmet is designed with a one-click emergency assistance function. Deaf and mute individuals can easily send a distress signal to a pre-set contact with a simple operation, ensuring they can receive timely help.

[0077] 3. Navigation function: Provides real-time route planning and navigation information for deaf and mute people, helping them reach their destinations more conveniently.

[0078] 4. Thermal imaging and night vision functions: help deaf and mute people better observe their surroundings at night or in low-light environments, improving safety.

[0079] When using the product of this invention:

[0080] Data collection:

[0081] Temperature and toxic gas sensors collect environmental data (temperature and concentration of harmful gases) in real time and send this data to the controller.

[0082] The camera captures images of the environment in front, the distance sensor measures the distance between the helmet and objects in front, and the thermal imaging module provides thermal radiation images. This data is also transmitted to the controller in real time.

[0083] The navigation module receives satellite positioning signals and inertial navigation data, calculates the current position and direction of travel, and sends the data to the controller.

[0084] Data processing and analysis:

[0085] The controller receives and processes data from various sensors, and makes judgments and analyses based on preset algorithms and logic.

[0086] For example, the controller compares the temperature sensor data with a preset safe temperature range, and triggers an alarm if the temperature exceeds the range.

[0087] Similarly, data from toxic gas sensors will be analyzed to detect whether the concentration of harmful gases exceeds the standard.

[0088] Algorithm Flow

[0173] Comprehensive judgment

[0174] In practical applications, the controller simultaneously monitors temperature and toxic gas concentration, and determines whether to trigger an alarm based on these conditions. This can be achieved through a comprehensive judgment logic:

[0175]

pseudo

[0176] / / Assuming trigger_alarm() is a generic alarm triggering function

[0177] / / It can perform corresponding operations based on the specific alarm type (temperature or toxic gas).

[0178] if(T<T_min||T> T_max){

[0179] trigger_alarm("Temperature");

[0180] }

[0181] if (C>C_threshold){

[0182] trigger_alarm("Gas");

[0183] }

[0184] Alternatively, if you want to check both temperature and gas concentration in a single conditional statement:

[0185]

pseudo

[0186] if(T<T_min||T> T_max||C>C_threshold){

[0187] trigger_alarm();

[0188] }

[0189] In this comprehensive assessment, an alarm will be triggered if either the temperature or the concentration of toxic gas exceeds the safe range.

[0190] Decision-making and output:

[0191] Based on the data analysis results, the controller makes decisions and controls the corresponding modules to output.

[0192] If the temperature or gas data is abnormal, the controller will trigger the alarm to emit an audible and visual alarm signal, and display relevant warning information through the HUD information display module and the head-up display screen.

[0193] Navigation information will be displayed to the wearer in real time through the HUD information display module to assist them in determining direction and planning routes.

[0194] Interaction and feedback:

[0195] Wearers can interact with the controllers through the interactive device on the helmet (head-up display) to adjust settings or view more information.

[0196] The controller adjusts the working status of each module according to the wearer's instructions and provides real-time feedback.

[0197] Each sensor and module is electrically connected to the controller via waterproof and dustproof wires or flexible circuit boards, ensuring stable data transmission and normal module operation. The interface design adopts a standardized and modular approach, facilitating future maintenance and upgrades. The controller employs a high-performance microprocessor or embedded system, possessing powerful data processing capabilities and abundant interface resources. An integrated power management module within the controller provides a stable power supply to all sensors and modules.
