Technical Field

[0001] This invention belongs to the field of protective device technology, specifically to an intelligent head protection device with a double-layer structure. Background Technology

[0002] Fire protection equipment refers to a series of protective gear worn by firefighters during firefighting and rescue operations, designed to protect them from various hazards at the fire scene. Fire helmets are an important protective device; however, most existing helmets are single-layered, with poor heat insulation, inadequate cushioning, and loosely designed modules. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides an intelligent head protection device with a double-layer structure to solve the problems of poor heat insulation, poor cushioning effect, and loose module setting.

[0004] To achieve the above objectives, the present invention provides an intelligent head protection device with a double-layer structure, comprising an outer shell and an inner shell, wherein the inner shell is disposed inside the outer shell; a cavity is formed between the outer shell and the inner shell, and a protective lens is disposed on the front side of the inner shell.

[0005] In some alternative implementations, the inner shell includes an inner helmet body, with a first baffle on one side of the inner helmet body and a second baffle on the other side of the inner helmet body.

[0006] In some alternative implementations, the first baffle is provided with at least one through hole, and a first camera, or a laser light, or an infrared thermal imager is provided in the through hole for transmitting signals to or collecting signals from the outside world.

[0007] In some alternative implementations, the second baffle (4) is provided with at least one through hole, the through hole being provided with a second camera for taking pictures and recording videos of the outside world; and, or a lighting system for lighting.

[0008] In some alternative implementations, AR glasses are also installed on the top of the cavity. The AR glasses have a retracted posture. When retracted, the AR glasses are located inside the cavity. When the AR glasses are pulled out, they are located outside the goggles and are used to project the scene environment and the firefighter's physical indicators.

[0009] In some optional implementations, the cavity houses a camera module, a battery module, a main control module, a ventilation module, a communication system module, a sensor module, a positioning system module, and a lighting module. The power output of the battery module is connected to the power receivers of the camera module, main control module, ventilation module, communication system module, sensor module, positioning system module, and lighting module, respectively. The battery module supplies power to the camera module, main control module, ventilation module, communication system module, sensor module, positioning system module, and lighting module. The camera module is used for recording video. The main control module coordinates and controls the operation of other modules, running the helmet's operating system and applications. The ventilation module improves air circulation and regulates temperature and humidity. The communication system module provides wireless communication capabilities for internal team communication or contact with the outside world. The sensor module collects ambient environmental data. The positioning system module determines the wearer's location. The lighting module provides illumination in low-light environments.

[0010] In some alternative implementations, reinforcing ribs are also provided inside the cavity to separate the camera module, battery module, main control module, and ventilation module.

[0011] In some alternative implementations, the outer shell (1) surface is provided with reflective strips.

[0012] In some alternative implementations, an external explosion-proof flashlight or other equipment is mounted on the outer surface of the outer shell (1).

[0013] In some alternative implementations, the cavity can also be filled with cushioning material. Compared with the prior art, the present invention has the following beneficial technical effects: A smart head protection device with a double-layer structure includes an outer shell, which serves as the outermost layer of the helmet and is typically made of a robust material, such as high-strength plastic or composite material, to resist impact and penetration. An inner shell is disposed inside the outer shell, which is made of a lighter material and designed to provide additional cushioning protection. It may also contain energy-absorbing properties to reduce the impact force on the wearer. The inner shell also includes an adjustable suspension system and padding to ensure the helmet fits different head shapes and provides a comfortable wearing experience. A cavity is formed between the outer and inner shells. This cavity is a key feature, providing additional cushioning space. This space can accommodate different functional modules and integrate various smart technologies, such as a built-in communication system, enabling the wearer to communicate with their team. The device facilitates communication between members or the command center. It incorporates an environmental monitoring sensor module to monitor factors such as temperature, humidity, and toxic gases; a built-in positioning system module, such as GPS, to help track the wearer's location; and built-in health monitoring equipment to monitor the wearer's physiological indicators, such as heart rate and body temperature. The inner and outer layers include ventilation holes or channels to improve airflow and reduce heat and moisture buildup. An internal lighting device, such as a headlamp or LED light, provides illumination in low-light environments. The cavity can be filled with energy-absorbing materials, such as foam or gel, to further enhance impact absorption. A protective lens, typically made of transparent, impact-resistant materials like polycarbonate, is located on the front of the inner shell to protect the eyes and face from flying debris and fragments. The mask is connected to the inner shell, providing a sealed protection and good cushioning. The module design is compact.

[0014] Furthermore, the first baffle is provided with several through holes, which are used by the first camera, laser light, and infrared thermal imager to transmit signals to or collect signals from the outside world. By providing through holes on the baffle, sensor modules such as cameras, laser lights, and infrared thermal imagers can be integrated into the helmet, providing enhanced vision and monitoring capabilities. The through holes allow these devices to transmit or collect signals from the outside world, such as video streams, illumination beams, and thermal imaging data. The through holes protect these sensitive devices from dust, moisture, and other potential damage. The position and size of the through holes can be optimized to ensure that the sensor modules have a clear field of view and maximize their functionality. The through holes make the installation, maintenance, and replacement of sensor modules easier. The through holes need to be compatible with the size and shape of various sensor modules to ensure that they can be fitted and installed correctly. The edges of the through holes are smoothly finished to avoid injury to the wearer in emergency situations. For devices that may generate heat, such as infrared thermal imagers, the through holes are designed to meet heat dissipation requirements. This design, by providing through holes on the first baffle, not only improves the functionality of the smart head protection device but also enhances its adaptability and practicality in complex environments. Various factors need to be considered during setup to ensure that the integration of sensor modules is both effective and safe.

[0015] Furthermore, the second baffle has several through holes to assist the second camera in taking photos and videos of the outside world, as well as providing laser guidance through the laser light. This design enhances the functionality and application range of the intelligent head protection device. The combined use of the second camera and the laser light provides richer and more precise visual assistance, helping the wearer to locate and observe in complex environments. The two camera modules can provide images from different angles or perspectives, increasing scene coverage and improving monitoring and recording capabilities. The laser light can be used for long-distance guidance, location, or communication with others, especially in environments with limited visibility. The through holes allow the signals from the camera and laser light to transmit freely, ensuring that the device can effectively collect external information. The through holes on the baffle provide additional physical protection for the camera and laser light. The through holes facilitate the inspection, maintenance, and replacement of the camera and laser light. The through holes are compatible with the size, shape, and installation requirements of the second camera and laser light. By incorporating through holes on the second baffle, the intelligent head protection device can integrate more functions and improve its performance in specific tasks, such as search and rescue.

[0016] Furthermore, placing AR glasses on the top of the cavity of the intelligent head protection device is a highly innovative design. It integrates augmented reality technology into the firefighter's helmet to enhance on-site awareness and operational efficiency. When not in use, the AR glasses can be retracted into the cavity, saving space and maintaining the helmet's compact shape. When AR functionality is needed, the glasses can be quickly pulled out and placed outside the visor for immediate use. The AR glasses provide additional visual information, such as real-time data of the on-site environment and the firefighter's physiological indicators (e.g., heart rate, blood oxygen saturation), while allowing firefighters to clearly see the real world. AR technology can overlay virtual information onto the real world, assisting firefighters in... Navigating complex environments, identifying hazards, or receiving instructions from command centers, the integrated setup of AR glasses and helmets means they can share power, sensor modules, and communication systems, simplifying the system architecture. This setup allows firefighters to easily operate the AR glasses without additional handheld devices. In emergencies, AR glasses can provide crucial information, helping firefighters make quick decisions. This setup, by integrating AR technology into intelligent head protection devices, significantly enhances firefighters' information acquisition capabilities during missions, improving operational safety and efficiency. However, the setup requires comprehensive consideration of various factors to ensure that the integration of AR glasses is both effective and safe, while also providing a good user experience.

[0017] Furthermore, the cavity houses camera modules for real-time video monitoring, recording of the scene, or communication with the command center via video transmission; the battery module provides power to all electronic components, requiring sufficient capacity to ensure long usage time and potentially supporting fast charging; the main control module, acting as the brain of the smart helmet, coordinates and controls the operation of other modules, running the helmet's operating system and applications; the ventilation module may contain miniature fans or vents to improve airflow, helping to regulate the temperature and humidity of the wearer's head and increase comfort; the communication system module provides wireless communication capabilities, such as Bluetooth, Wi-Fi, or dedicated radio frequencies, for internal team communication or external contact; sensor modules include motion sensors and environmental monitoring sensors (such as temperature, humidity, and gas concentration) to collect data on the surrounding environment; and a positioning system module, such as a GPS module, is used to determine the wearer's location. The helmet's location is particularly useful for navigation and search and rescue missions; the lighting module includes LED lights or other lighting equipment to provide illumination in low-light environments; the power output of the battery module is connected to the power receivers of the camera module, main control module, ventilation module, communication system module, sensor module, positioning system module, and lighting module; the advantage of this setup is that all necessary electronic components and modules are integrated into a compact space, facilitating management and use; each module can be set to be replaceable or upgradeable, facilitating maintenance and adaptation to future technological developments; the integrated smart module enhances the helmet's functionality, extending it beyond traditional protection; the built-in battery module ensures that all modules can operate independently without an external power source; this intelligent head protection device setup, by integrating key functions inside the helmet, provides firefighters, industrial workers, security personnel, and others with an efficient and multifunctional personal protective solution.

[0018] Furthermore, the cavity is equipped with reinforcing ribs to separate the camera module, battery module, main control module, and ventilation module. This design enhances structural stability and safety. The ribs strengthen the cavity's structure, making it more robust and able to withstand external impacts. Separating different modules with ribs helps maintain their positional stability, preventing collisions or displacement during impacts. The ribs also act as thermal insulation, helping to disperse and isolate heat generated by different modules, especially components like the battery and main control modules that may generate significant heat. The modular design makes maintenance and replacement of components easier, as they are separately secured between the ribs. The use of ribs improves helmet safety by physically isolating components and reducing... Potential fault propagation, such as a battery module failure, will not directly affect other modules; reinforcing ribs may help improve electromagnetic compatibility by isolating different electronic modules and reducing electromagnetic interference between them; reinforcing ribs can provide additional shock absorption, absorbing and dispersing impact forces to protect internal modules; the use of reinforcing ribs provides flexibility in the setup, allowing their position and shape to be adjusted as needed to accommodate the size and shape of different modules; as part of the weight distribution, reinforcing ribs help balance the weight of the helmet, improving wearing comfort; the use of reinforcing ribs can improve the durability of the helmet, enabling it to withstand wear and tear during long-term use; by incorporating reinforcing ribs inside the cavity, the setup of the smart head protection device not only improves the overall structural stability and safety but also facilitates the maintenance and upgrading of internal components.

[0019] Furthermore, the top of the outer shell features reflective strips to improve visibility, making the wearer more easily seen by others at night or in environments with poor visibility. Increased visibility can reduce the risk of accidents and protect the wearer's safety when working in emergency or hazardous environments. It also serves as a warning sign, alerting others to the wearer's presence. In teamwork or large-scale operations, reflective strips can help identify the location of team members or commanders. Other features may also include integrated LED lights to further enhance visibility. Integrating reflective strips into the top of the outer shell is a practical option when designing intelligent head protection devices with a dual-layer structure.

[0020] Furthermore, a raised section on one side of the bottom outer shell features a battery indicator button. This button activates the helmet's built-in battery level indicator, allowing the wearer to quickly check the current battery level and ensure the device is available when needed. AR glasses function buttons are used to activate or adjust AR display settings, such as switching views, adjusting transparency, or launching specific AR applications. An emergency rescue button allows for quick sending of distress signals or activation of preset emergency response procedures in emergencies, improving rescue efficiency. Camera control buttons control the camera's on / off state, as well as its photo and video recording functions. A raised section on the other side of the bottom outer shell features an LED light control button, used to control the integrated LED lights on / off or adjust their modes, such as switching between different flashes. The flashing mode enhances visibility or allows for signal transmission. The raised sections on both sides of the bottom of the outer shell are ergonomically designed for ease of use, making the control buttons easily accessible and operable. These raised sections also ensure easy operation even when wearing gloves. Grouping the function buttons on both sides of the helmet facilitates memorization and quick access. The integration of multiple control buttons indicates the helmet's diverse intelligent functions, enhancing its practicality and flexibility. Different buttons control different functions, allowing the helmet to adapt to various work environments and needs. This intelligent head protection device, with its integrated control buttons on the raised sections of the outer shell, provides a user-friendly interaction method, enabling the wearer to quickly and conveniently control the helmet's various intelligent functions.

[0021] Furthermore, the raised portion on the outer side of the outer shell allows for the attachment of equipment such as explosion-proof flashlights. This enhances its practicality and adaptability. Providing attachment points allows the helmet to quickly install or replace accessories according to specific mission or environmental needs. Attached explosion-proof flashlights can provide additional illumination in low-light or no-light environments, helping firefighters or workers see their surroundings. The raised portion also facilitates one-handed operation, allowing for quick fixing or removal of external equipment. In addition to explosion-proof flashlights, these attachment points can also be used for other equipment, such as communication devices, night vision goggles, or facial recognition systems. By incorporating attachment points into intelligent head protection devices, their applicability and flexibility in various working environments can be significantly improved, while ensuring the wearer's safety and work efficiency.

[0036] The cavity houses camera modules for real-time video monitoring, recording of the scene, or communication with the command center via video transmission; the battery module provides power to all electronic components, requiring sufficient capacity for extended use and potentially supporting fast charging; the main control module, acting as the brain of the smart helmet, coordinates and controls the operation of other modules, running the helmet's operating system and applications; the ventilation module may contain miniature fans or vents to improve airflow, helping to regulate the wearer's head temperature and humidity for increased comfort; the communication system module provides wireless communication capabilities, such as Bluetooth, Wi-Fi, or dedicated radio frequencies, for internal team communication or external contact; sensor modules include motion sensors and environmental monitoring sensors (such as temperature, humidity, and gas concentration sensors) to collect data on the surrounding environment; and a positioning system module, such as a GPS module, is used to determine the wearer's location.

[0038] The inner shell 2 includes an inner helmet body 6, with a first baffle 4 on one side of the inner helmet body 6 and a second baffle 5 on the other side. The inner helmet body 6 is the main part that constitutes the inner layer of the helmet, while the first baffle 4 and the second baffle 5 are located on the outer sides of the inner helmet body 6, which may be used to provide additional protection or support.

[0039] The first baffle 4 has several through holes, which are used by the first camera, laser light, and infrared thermal imager to transmit or collect signals from the outside world. By providing through holes on the baffle, sensor modules such as cameras, laser lights, and infrared thermal imagers can be integrated into the helmet, providing enhanced vision and monitoring capabilities.

[0041] AR glasses can also be installed at the top of the cavity. The AR glasses have two positions: retracted and extended. In the retracted position, the AR glasses are tucked inside the cavity; in the extended position, they are extended and located outside the visor, used to project the scene environment and the firefighter's physiological indicators. Installing AR glasses at the top of the cavity of the intelligent head protection device is a highly innovative design. It integrates augmented reality technology into the firefighter's helmet to enhance on-site perception and operational efficiency. When not in use, the AR glasses can be retracted inside the cavity, saving space and maintaining the helmet's compact shape. When AR functionality is needed, the glasses can be quickly extended and placed outside the visor for immediate use. The AR glasses can provide additional visual information, such as real-time data of the scene environment and the firefighter's physiological indicators (e.g., heart rate, blood oxygen). AR technology allows firefighters to clearly see the real world, including saturation and other parameters.

Various factors need to be considered during setup to ensure that the integration of AR glasses is both effective and safe, while providing a good user experience.

[0042] The rear of the cavity is equipped with a ventilation module, and the outer shell and inner shell at the corresponding positions are provided with through holes to form convection with the fan for cooling the helmet.

[0043] The cavity is also equipped with reinforcing ribs to separate the camera module, battery module, main control module and ventilation module.

[0044] The cavity can also be filled with cushioning material. Specific Implementation

[0045] A smart head protection device with a double-layer structure includes an outer shell 1, an inner shell 2 disposed inside the outer shell 1, a certain cavity being formed between the outer shell 1 and the inner shell 2, and a protective lens 3 disposed on the front side of the inner shell; the outer shell 1 and the inner shell 2 are connected by buckles or screws.

[0046] The outer shell features reflective strips on its top, L-shaped and located on either side of the raised section at the top of the helmet. These strips are typically made of synthetic fiber fabric, offering good reflectivity and durability. Besides synthetic fiber fabric, there are also reflective strips made of reflective lattice material, used in safety clothing. When applied correctly, this material enhances the wearer's visibility at night or in low-light conditions. ORAFOL Meilite utilizes ORAFOL reflective technology, combining a solid pyramid with a soft, weather-resistant polymer film through a lamination process. It is suitable for various climatic conditions. The choice of reflective strip material depends on the application scenario and required reflectivity to ensure sufficient visibility and safety at night or in low-light environments.

[0047] The bottom side of the outer shell has a raised part with a power display button, an AR glasses function button to the right of the power display button, an emergency rescue button below the power display button, a camera control button below the AR glasses function button, and an LED light control button on the other raised part of the bottom side of the outer shell.

[0048] The inner shell includes an inner helmet body, with a first baffle on one side of the inner helmet body and a second baffle on the other side of the inner helmet body.

[0049] The first baffle is provided with several through holes, which are used, from top to bottom, to allow the first camera, laser light and infrared thermal imager to pass through.

[0050] The second baffle is provided with several through holes, which are used from top to bottom to allow the second camera and the lighting system to pass through.

[0051] The rear of the cavity is equipped with a ventilation module, and the outer shell and inner shell at the corresponding positions are provided with through holes to form convection with the ventilation module for cooling the helmet; the ventilation module is generally a fan, which can be set according to needs.

[0052] The cavity also contains reinforcing ribs to separate the camera module, battery module, main control module, and ventilation module. A reinforcing rib is a component used to enhance the strength of materials or structures, and is commonly used in engineering and installation fields. Reinforcing ribs can be made of different materials, such as metal, plastic, carbon fiber, etc., depending on the application requirements and cost-effectiveness.

[0053] The cavity can also be filled with cushioning material; cushioning material is used to absorb and disperse impact force and protect the product from damage. Types of cushioning materials include: EPS foam board, polyethylene foam EPE (commonly known as pearl cotton), polyurethane foam, paper cushioning packaging materials, plastic cushioning packaging materials, EPE, EPP, PE, PU, ​​EVA and EPS, polyurethane foam, etc. The choice of cushioning material depends on the type, weight, shape of the product to be protected and the expected transportation and storage conditions.

[0054] The working principle of this invention is as follows: Wear the protective device, turn on the camera, flash, infrared thermal imager, sensor module, positioning system module, and communication system module. When the working temperature is high, the ventilation module is turned on to cool the inside of the helmet. When the environment is relatively dark, the lighting module is turned on to provide illumination.
