Description

Technical Field

[0001] The invention relates to the technical field of safety protection equipment, in particular to a modular multifunctional bomb disposal helmet. Background Art

[0002] Existing bomb disposal helmets are usually used to protect workers from explosion shock and fragments in dangerous environments. However, the bomb disposal helmets of the prior art have great limitations in terms of functional integration, modular design, comfort and ease of operation. Traditional bomb disposal helmets have obvious deficiencies in protection capabilities and protection areas. Their designs are usually only able to cover a limited area of ​​the head and cannot provide comprehensive protection for key parts such as the brain and neck. When faced with the powerful shock wave of an explosion, existing helmets often lack sufficient shock-absorbing and buffering structures, making it difficult to effectively absorb the impact of the shock wave on the brain, which may cause serious injuries to workers in explosion scenes. This lack of protection results in the inability of existing helmets to provide the required explosion-proof performance and reliable buffering protection effects when faced with strong explosion shock waves.

[0003] In addition, most traditional EOD helmets adopt an integrated design and lack modular components, which makes it difficult for the helmet to flexibly adapt to different operating scenarios, and it is time-consuming and costly to repair and replace damaged parts. This non-modular structure limits the scalability of the helmet's functions and the convenience of maintenance.

[0004] In summary, the bomb disposal helmets of the prior art have obvious deficiencies in terms of protection area, shock wave shock absorption and buffering effect, and overall explosion-proof performance, and are difficult to provide adequate protection for operators in high-risk operation scenarios. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a modular multifunctional bomb disposal helmet to solve the deficiencies of the prior art bomb disposal helmets in terms of protection area, shock wave shock absorption and buffering effect, and overall explosion-proof performance.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a modular multifunctional bomb disposal helmet, comprising:

[0007] The helmet shell is the main carrier of the EOD helmet and the mounting base for the protective components and control module;

[0008] The transparent visor, mounted on the helmet shell, includes a high-energy-absorbing polycarbonate layer and a built-in electric heating defog system, which has anti-fogging and defogging functions;

[0009] a ventilation system, mounted at the rear of the helmet shell, comprising at least one fan for providing air circulation within the helmet;

[0010] A lighting system, mounted on the front of the helmet, comprising at least one adjustable light;

[0011] Communications system, including built-in anti-interference headset and microphone, supporting both wireless and wired communications;

[0012] The control system, including a wrist controller, controls the helmet's lighting, fan speed, defogger, and communication functions through a user interface.

[0013] The present invention also provides a modular multifunctional control system for an explosive ordnance disposal helmet, comprising:

[0014] Helmet control module, used to manage various functions of the helmet;

[0015] A wrist controller is arranged on the operator's arm, has multiple function buttons and a display interface, and can control various functional modules of the helmet system. The wrist controller is connected to the helmet control module through a control cable;

[0016] A power supply device, independently configured, used to provide power support for the helmet control module and the wrist controller, the power supply device and the control module are connected via a power cable;

[0017] A communication module, including an anti-interference headset and a microphone built into the helmet, used for voice communication between the operator and the external device, supporting the switching of wireless communication and wired communication, wherein the wireless communication is carried out through an intercom connected to the voice controller, and the wired communication is realized through a wired communication cable reel;

[0018] The control signal transmission module is used to transmit control signals between the wrist controller and the helmet control module to achieve integrated control of each module of the helmet.

[0019] The present invention provides a modular multifunctional bomb disposal helmet, which has the following beneficial effects:

[0020] 1. The present invention adopts modular design. Each functional module such as ventilation system, lighting system, communication system, video recording function and control system can be independently installed or replaced, which is convenient for flexible configuration according to different EOD environments. The modular design makes the maintenance, repair and upgrade of the entire system more convenient, which helps to improve the service life and environmental adaptability of the helmet.

[0021] 2. The transparent mask of the present invention adopts a multi-layer structure, including a carbon fiber layer, a bulletproof layer and a transparent cover layer. By integrating an electric heating defogging film, it can effectively prevent the penetration of sharp fragments in harsh environments while maintaining the clarity of the inner side of the mask. This multi-layer structure design can not only provide strong protection for operators, but also ensure that the field of vision is not blocked in environments with high humidity or large temperature differences, thereby improving the safety and accuracy of operations.

[0022] 3. The ventilation system of the present invention is used in conjunction with the curved airway structure of the helmet lining to provide efficient air flow during operation. The ventilation airway on the lining can guide the airflow from the fan to the facial area, avoiding condensation of water vapor in the mask and improving wearing comfort. The fan of the ventilation system also plays a role in balancing the center of gravity of the helmet, forming a balance with the transparent mask at the front, and improving wearing stability.

[0023] 4. The lighting system of the present invention includes a dual-lamp head assembly with adjustable direction, which can adjust the light intensity and direction according to the ambient light conditions to ensure sufficient lighting at the work site. This adjustable design not only increases the accuracy of the operation, but also ensures that the lamp head remains stable during the operation through the damping design between the spherical lampshade and the fixing frame, reduces unnecessary light interference, and improves the safety and efficiency of the operation.

[0024] 5. The helmet of the present invention integrates a wireless and wired communication system to ensure stable real-time communication between the operator and the back-end command center in different environments. Through the wireless intercom and voice controller, the operator can communicate without manual operation; and the wired communication module provides protection in special environments with limited signals to ensure that the information transmission between the operation site and the command center will not be interrupted.

[0025] 6. The wrist controller of the present invention realizes integrated control of each module through an intuitive interface and multi-function buttons. The operator can adjust the lighting, ventilation, defogging and communication functions in the helmet at any time to ensure adaptability and operational convenience in different environments. The modular integration of the control system not only simplifies the operating process of the operator, but also reduces the risk of misoperation through visual indicator lights and system self-checking functions, ensuring the safety of the operation process.

[0026] 7. The ventilation system of the present invention is combined with the defog function of the transparent mask to effectively prevent the mask from blurring due to moisture and temperature difference. The lighting system further ensures that the operator has a clear field of vision when the lighting conditions are poor. The three work together to ensure the operator's accurate operation and stable vision in various harsh environments, thereby improving the overall success rate of the operation.

[0045] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Please refer to the attached Figure 1 -Attached Fig.16 The present invention provides a modular multifunctional explosive ordnance disposal helmet to provide comprehensive safety protection for explosive ordnance disposal workers in high-risk environments, and to improve comfort and operational convenience during operations. The helmet includes a helmet shell 10, a helmet liner 11, an adjustable pad, a mask, a mask locking device, a head fan, a lighting device, a recording device, a wrist controller 61, etc. The specific implementation of each module will be described in detail below in conjunction with the accompanying drawings.

[0047] The helmet shell 10 of the present invention serves as a main protective component of the explosive ordnance disposal helmet and a mounting base for other modules, and is intended to provide reliable head protection for explosive ordnance disposal workers in dangerous environments.

[0048] like Figure 2 As shown, the main body of the helmet shell 10 is made of multiple layers of bulletproof materials, including high-strength fiber materials and impact-resistant composite materials, forming a strong and lightweight protective structure. Preferably, the shell body is molded to ensure that it can withstand the impact of large explosion shock waves and fragments while remaining lightweight to reduce the burden on the wearer.

[0049] The main function of the front part 10a of the housing is to provide protection for the face of the operator, which covers the forehead, the facial area on both sides and the ears. The front part of the housing is provided with mounting interfaces for fixing the transparent mask 20, which cooperate with the rotating shaft 25 and the locking mechanism on the transparent mask 20 to ensure that the mask can be reliably fixed and provide the necessary lifting function.

[0050] The rear part 10b of the shell adopts an inwardly inclined transition design, so that the helmet can fit the wearer's neck and ensure that there is no interference when the wearer raises or lowers his head. The design of the inclined structure also increases the protective area of ​​the helmet for the back neck, ears and side neck, further improving the overall protective performance of the helmet.

[0051] The top 10c of the shell adopts an arc-shaped structural design, which conforms to the natural shape of the human head and can effectively reduce the impact concentration area, thereby dispersing the impact force acting on the top of the helmet and increasing the protective effect.

[0052] like Figure 3 As shown, a layer of EPP (expanded polypropylene) shock-absorbing lining 11 is provided on the inner surface of the helmet shell 10. The thickness of the lining 11 is about 20 mm and is closely fitted to the helmet shell 10. The function of the lining 11 is to absorb the shock wave generated by the explosion, reduce the direct impact force on the user's brain, and thus improve the overall protective performance.

[0053] The top of both sides of the liner 11 are provided with curved grooves to form an airway connected to the ventilation system 30, which is used to quickly guide the airflow generated by the fan at the rear of the helmet to the face area, thereby improving the air circulation effect inside the helmet. The design of the grooves ensures ventilation without affecting the shock absorption effect of the liner 11.

[0054] like Figure 4 As shown, a protective baffle 111 is provided in the area corresponding to the fan installation position in the liner 11. These protective baffles 111 are formed by pressing bulletproof material, and their function is to provide additional protection for the installation hole, prevent the fan installation hole in this area from becoming a weak point in the protection, and ensure that the overall protective performance of the helmet is not damaged.

[0055] The helmet shell 10 provided by the present invention is the core structure of the explosive disposal helmet, and adopts multi-layer bulletproof materials and reasonable geometric shape design to ensure the protection safety of the head in dangerous environments. Combined with the matching design of the lining 11, the airway structure and the protective baffle 111, the helmet shell 10 not only provides a solid external protection, but also pays attention to the comfort and convenience of the wearer.

[0056] The transparent mask 20 of the present invention is a key protective component in the explosive ordnance disposal helmet, and is intended to provide physical facial protection and clarity of working vision for operators.

[0057] like Figure 5 As shown, the transparent mask 20 includes a carbon fiber layer 21, a bulletproof layer 22, a transparent cover 23 and an electrically heated defogging film 24. This multi-layer design ensures high-strength protection while satisfying transparency and functionality.

[0058] The carbon fiber layer 21 is the outer component of the mask, made of carbon fiber material, and has the characteristics of light weight and high strength. A window area is provided in the middle of the carbon fiber layer 21 to provide an observation field of view so that the operator has a good field of view during the bomb disposal operation. At the same time, the carbon fiber layer 21 has a deformation transition design, which enables it to effectively protect the operator's face and jaw area, and maintain smooth movements when raising, lowering, and turning the head left and right. The carbon fiber layer 21 is tightly fitted with the bulletproof layer 22 at the edge to ensure that the two can absorb energy together when impacted.

[0059] The bulletproof layer 22 is located inside the carbon fiber layer 21 and is pressed from multiple layers of ultra-high molecular weight polyethylene fibers. Its design purpose is to further enhance the overall protective capability of the mask. The shape of the bulletproof layer 22 is consistent with the carbon fiber layer 21 to ensure a close fit and reduce the gap between the two. The window area is slightly larger than the window area of ​​the carbon fiber layer 21 to ensure that the vision of the operator is not affected. The carbon fiber layer 21 and the bulletproof layer 22 are fixed by rivets in a special hydraulic tooling to ensure a close fit and connection reliability between the two.

[0060] The transparent cover 23 is installed in front of the carbon fiber layer 21 and the bulletproof layer 22. It is made of high-transmittance polycarbonate material and has a thickness of 20 mm, ensuring that the mask does not affect the observation of the operation while providing protection. The size of the transparent cover 23 is designed to be slightly larger than the window area of ​​the carbon fiber layer 21, so that the transparent cover 23 and the carbon fiber layer 21 form an overlapping structure in the edge area to improve the overall protection.

[0061] The electric heating defogging film 24 is attached to the inner side of the transparent cover 23 and is used to heat the inner surface of the cover to prevent the condensation of water vapor in a high humidity environment from affecting the field of vision. The defogging film is activated by the circuit control unit to quickly remove the condensation of water vapor and keep the window area of ​​the transparent cover 20 clear, thereby improving the accuracy and safety of the operation.

[0062] like Figure 6-Figure 8 As shown, the design of the transparent mask 20 also includes a flip-up structure and a locking and fixing device 26 to provide adjustment and stability of the mask.

[0063] The transparent mask 20 is connected to the helmet shell 10 via the rotating shafts 25 on both sides. The rotating shafts 25 are arranged along the horizontal axis, allowing the mask to be flexibly switched between the lifted state and the working state. This design allows the transparent mask 20 to be quickly lifted to the top of the helmet when not in use, thereby improving the ventilation effect on the operator's face, especially relieving fatigue when the operator temporarily stops working.

[0064] The locking and fixing device 26 is provided on one side of the mask. The locking and fixing device 26 is a prior art and will not be described in detail here. When in use, pressing the locking button can unlock the rotation of the mask, so that the mask can be freely adjusted between the upper and lower positions. When the locking button is released, the spring will cause the locking device to snap into the corresponding slot to ensure that the mask is stably locked in the upper or working position.

[0065] like Figure 8 As shown, a rotating hole 21a, a first card slot 21b and a second card slot 21c are provided on the carbon fiber layer 21 of the mask. The two card slots are arranged at specific angles relative to the rotating hole 21a. The first card slot 21b is used for angle locking when the mask is in an upward state, and the second card slot 21c is used for angle locking when the mask is in a working state, thereby ensuring that the field of view of the mask meets the operating requirements.

[0066] The transparent mask 20 in the present invention provides comprehensive protection for the face through the integrated design of the carbon fiber layer 21, the bulletproof layer 22, the transparent cover 23, the electric heating defogging film 24, the flip-up structure and the locking and fixing device 26, while ensuring a clear working field of vision and convenience of wearing.

[0067] like Fig. 9 As shown, the ventilation system 30 is installed at the rear of the helmet shell 10, and mainly includes components such as a fan assembly 32, a rear mounting seat 31, a rear mounting cover 33 and a control panel 34. The detailed description of each part is as follows:

[0068] The fan assembly 32 includes at least two fans, which are installed at the rear of the helmet shell 10. Each fan is designed to be small in size, large in air volume and low in noise. The air volume of a single fan is about 200 liters / minute, and the total air volume of the two fans is 400 liters / minute, which can meet the ventilation needs of operators in high temperature and high humidity environments.

[0069] The fan assembly 32 is positioned at the upper portion of the helmet shell 10 so as to cooperate with the airway structure of the helmet lining 11 so that fresh air can quickly flow to the facial area through the airway, ensuring unimpeded breathing for the operator and improving the comfort of the operation.

[0070] The fan is fixed to the rear of the helmet shell 10 through the rear mounting seat 31. The rear mounting seat 31 is not only a mounting carrier for the fan, but also has the function of circuit connection. An aviation plug interface is provided on it, which is used to connect the fan and the control board 34 for power supply and communication, so as to realize control operations such as starting, stopping and speed adjustment of the fan.

[0071] The rear mounting seat 31 adopts a modular design, which is convenient for quick removal and reinstallation when maintenance, cleaning or replacement of the fan is required, thereby ensuring the long-term reliability of the helmet.

[0072] The rear mounting cover 33 is used to cover the fan and the rear mounting seat 31. A filter structure is provided in the rear mounting cover 33 to prevent large particles of dust and foreign matter from entering the interior of the helmet, thereby protecting the overall operating reliability of the fan and the ventilation system 30.

[0073] The control panel 34 is installed in the control panel 34 installation box, and is used to adjust the speed and start and stop state of the fan. The control panel 34 is connected to the wrist controller 61, and the operator can flexibly adjust the operating state of the ventilation system 30 through the wrist controller 61 to adapt to different working environment requirements.

[0074] The control box cover is installed on the outside of the control board 34 to prevent external dust, water vapor and impact from damaging the control board 34.

[0075] After the fan of the ventilation system 30 is started, air enters the interior of the helmet from the filter on the rear mounting cover 33, then passes through the airway structure on the top of the helmet liner 11, and flows toward the facial area along the curved grooves.

[0076] The fan is controlled by the wrist controller 61. The operator can adjust the fan speed through the control system 60 according to the actual ambient temperature and humidity conditions, thereby increasing the ventilation volume in high temperature or high humidity environments and keeping the air inside the helmet fresh.

[0077] The modular design of the ventilation system 30 allows the fan assembly 32 and the rear mounting base 31 to be independently disassembled and assembled, thereby facilitating maintenance and replacement.

[0078] The ventilation system 30 of the present invention ensures that workers in a closed environment can have a good ventilation experience by providing components such as a fan assembly 32, a rear mounting seat 31, a rear mounting cover 33, a control panel 34 and a protective cover.

[0079] As an important component of the modular multifunctional bomb disposal helmet, the lighting system 40 of the present invention is intended to provide effective lighting for operators in low-light or complex environments to improve the safety and accuracy of operations.

[0080] like Figure 10-12As shown, the lighting system 40 is installed at the front of the helmet, and mainly includes a lamp head assembly 43, a lampshade and a lampshade fixing frame 42. The lighting system 40 is designed to provide a high-intensity, direction-adjustable light source to ensure that the operator can obtain stable lighting under complex lighting conditions.

[0081] The lighting system 40 includes two independent lamp head assemblies 43, which are installed in the lamp cover at the front of the helmet. The brightness of each lamp head can be adjusted according to the ambient light conditions to meet the needs of different working conditions.

[0082] The shell of the lamp holder assembly 43 is made of a plastic material that is resistant to high and low temperatures to ensure its reliability and service life under harsh environmental conditions.

[0083] like Fig.12 As shown, the lampshade is divided into an upper lampshade 42a and a lower lampshade 42b, and adopts a modular design to facilitate the installation and maintenance of the lamp holder. The lampshade and the lampshade fixing frame 42 are molded by plastic, and the inner side of the lampshade fixing frame 42 is a spherical structure, which matches the outer spherical surface of the lampshade, leaving a small gap in the middle.

[0084] The spherical design on the lampshade fixing frame 42 ensures that the lamp head can be adjusted over a wide range in both the vertical and horizontal directions, meeting the need for the direction of the light source to change at any time during operation and providing stable lighting support.

[0085] The lighting system 40 is installed on the dust cover 41 at the front of the helmet through the combination of the lampshade and the lampshade fixing frame 42. During installation, the lampshade is first combined with the lampshade fixing frame 42, and the corresponding positioning holes are aligned, and then fixed on the dust cover 41 by screws to ensure the stability of the combination.

[0086] The lighting system 40 is controlled through the wrist controller 61. The operator can turn on or off the lighting through the lighting switch button on the controller, and adjust the light brightness through the adjustment button to adapt to different ambient lighting conditions.

[0087] Through the ball center rotation adjustment function on the controller, operators can easily adjust the up and down, left and right irradiation direction of the lamp head so that the light can fully cover the working area.

[0088] The lighting system 40 adopts a modular design, which is convenient for combination or disassembly with other parts of the helmet. Through the standardized fixing frame and dust cover 41 interface, the lamp head, lamp cover and its fixing frame can be quickly assembled or replaced, thereby providing convenience when maintenance or upgrading is required.

[0089] The lighting system 40 of the present invention provides an efficient and flexible lighting solution through the integrated design of two lamp head assemblies 43, a spherical lampshade fixing frame 42, a dust cover 41 and an adjustment function, and adapts to the diverse needs in bomb disposal operations.

[0090] The communication system 50 of the present invention is an important component of the modular multifunctional bomb disposal helmet, and is intended to achieve real-time and efficient communication between the operating personnel and the back-end command center, ensuring timely and reliable transmission of information during the operation.

[0091] like Figure 13-Figure 15 As shown, the communication system 50 mainly includes an earphone 51, a microphone assembly 52, a wireless communication module, a wired communication module, and a control interface for selecting a communication mode through a wrist controller 61. The system supports both wireless and wired communication modes to meet the communication needs of different working environments.

[0092] The communication system 50 is equipped with two built-in anti-interference earphones 51, which are respectively installed on the left and right sides of the helmet shell 10, and the microphone is installed on the right side of the helmet shell 10. Both the earphones 51 and the microphone adopt noise reduction filtering technology to effectively reduce the interference of noise in the working environment on the communication quality and ensure clear voice transmission.

[0093] The earphone 51 is connected to the shell inside the helmet via an earphone 51 seat, and the earphone 51 seat is fixed with screws to ensure that the earphone 51 can remain stable during intense exercise or vibration.

[0094] The wireless communication module includes an intercom and a voice controller 53, which are used together to realize the wireless communication function without operation. The intercom 54a and the voice controller 53 at the operation end can be installed on the chest and right upper arm of the bomb disposal suit 100, so that the operator can realize convenient communication during the operation. Through the voice controller 53, the two intercoms are adjusted to the same channel, and the operation end and the command end can establish a real-time communication link.

[0095] The wireless communication module uses noise reduction and anti-interference technology to prevent the influence of conventional interference equipment in complex working environments. The design of the voice controller 53 allows operators to communicate with the command end through voice activation without manual keystrokes, ensuring that both hands remain free during operation and improving the efficiency and safety of operation.

[0096] The wired communication module connects the helmet system to the back-end communication equipment through a cable reel, and is suitable for working environments where wireless communication signals are limited, such as underground or highly shielded environments.

[0097] The operation of the communication system 50 is controlled by a wrist controller 61, which is worn on the arm of the operator to facilitate quick operation of various functions during the bomb disposal operation. The wrist controller 61 is provided with a plurality of buttons for controlling the volume of the earphone 51, selecting the communication mode (wireless or wired), and turning the microphone on and off. The operator can clearly understand the current communication status through the feedback of the button indicator light.

[0098] The communication interface of the wrist controller 61 extends along the arm through a cable to the multifunctional fixing belt on the bomb disposal suit 100 , and transmits data and power to the helmet shell 10 .

[0099] The communication system 50 supports both wireless and wired modes. The specific working modes are as follows:

[0100] In the wireless communication mode, the operator activates the wireless communication through the wrist controller 61, and the intercom at the operation end cooperates with the voice controller 53. After the two intercoms are adjusted to the same channel, two-way voice communication between the operation end and the back-end command end can be realized. The voice controller 53 can automatically answer the call through voice activation, eliminating the need for the operator to manually operate the intercom during the bomb disposal operation.

[0101] In an environment where wireless signals are limited or there is strong interference, the operator can switch the communication mode to the wired communication mode through the wrist controller 61. In the wired communication mode, the operator connects the helmet to the back-end communication device through a cable and uses the headset 51 to communicate, so as to ensure the smooth progress of the operation in a complex environment.

[0102] The communication system 50 in the present invention realizes efficient communication between the operator and the command end through the combination of the earphone 51 and the microphone assembly 52, the wireless communication module, the wired communication module and the wrist controller 61.

[0103] The control system 60 of the present invention is an important component of the modular multifunctional bomb disposal helmet. It is intended to provide operators with effective control of various modules of the helmet system through an integrated human-computer interaction interface, including lighting, ventilation, defogger, communication and other functions, so as to improve the safety and operational convenience of bomb disposal operations.

[0104] like Fig.16 As shown, the control system 60 mainly includes a wrist controller 61, a control circuit and a connection interface with other modules of the helmet. The control system 60 is connected to other modules of the helmet through a communication cable to achieve unified integrated control.

[0105] The wrist controller 61 is the core of the control system 60, which is worn on the forearm of the operator and fixed to the explosive disposal suit 100 by the webbing 62. It has multiple function buttons and a display interface. The design purpose of the wrist controller 61 is to provide a convenient control method for the operator during the explosive disposal operation, so that the operator can quickly adjust the various functions of the helmet while wearing the explosive disposal suit 100.

[0106] The outer shell of the wrist controller 61 is made of PC+ABS material, which has the characteristics of high strength and good weather resistance. The internal shielding design meets the use requirements of complex working environments. The structure adopts waterproof design, and the protection level reaches IP65 to ensure the reliability of the controller under harsh conditions.

[0107] The panel of the wrist controller 61 is equipped with multi-function buttons, including lighting control, fan control, defog start, communication switching, recording start, etc., as well as power display and self-test buttons.
