Description

Technical Field

[0001] This utility model relates to a communication auxiliary structure in head protection devices, specifically to a pilot helmet with a bone conduction structure. Background Technology

[0002] Helmet communication technology is a technology that allows users to communicate and interact wirelessly through helmet devices, primarily through components such as sensors, microphones, headphones, and displays integrated within the helmet. This technology is commonly found in military, aviation, virtual reality, and augmented reality fields, enabling functions such as voice communication, data transmission, and location tracking, allowing users to communicate and collaborate efficiently with other users or systems while wearing the helmet.

[0003] For pilot helmets, the quality of helmet communication technology directly affects the accuracy and efficiency of communication and information exchange during flight, and indirectly impacts flight safety. Traditional pilot helmets typically use air-conduction headphones to transmit sound, meaning sound is delivered to the user's ear via traditional headphones. In noisy environments, especially the high noise levels generated during flight, the sound transmission effect is severely affected, easily leading to unclear sound transmission and consequently causing errors when pilots hear instructions or communications.

[0004] Bone conduction technology is a technique that uses vibrations of the skull to transmit sound. It converts sound into vibrations through bone conduction headphones, which directly cause corresponding fluctuations in the perilymph via the skull, stimulating the cochlea to produce hearing. The advantage of bone conduction technology lies in its ability to provide better sound transmission in noisy environments, especially for pilots facing high-noise and complex conditions. It ensures clear transmission of sound information, helping pilots receive clear instructions while maintaining awareness of their surroundings in noisy environments. Integrating bone conduction technology with pilot equipment can further enhance the pilot's communication experience and information exchange efficiency. Utility Model Content

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] A pilot helmet with bone conduction structure includes an outer shell and an inner liner fitted inside the outer shell. An earphone cover is formed on the inner side of the outer shell corresponding to the ear position of the helmet. The earphone cover includes a leather shell and a soft inner liner formed inside the leather shell.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0023] See Figures 1-3 A preferred embodiment of a pilot helmet with a bone conduction structure is disclosed. In this embodiment, the pilot helmet with a bone conduction structure is mainly used in the aviation field to provide pilots with an efficient and clear communication experience during flight. The helmet structure and function in this embodiment will be described in detail below.

[0024] like Figure 1 As shown, the main body of the helmet includes the helmet body 2, the visor 1, and the helmet strap (chin strap). The helmet body 2 includes an outer shell 4 as a protective structure. This outer shell 4 is made of lightweight, high-strength materials, such as carbon fiber composites, to reduce the burden on the pilot's head while ensuring strength. The inner side of the outer shell 4 is lined with an inner lining material 7 as an impact-resistant cushioning material. At the same time, a soft, breathable fabric (such as mesh fabric or moisture-wicking fabric) is formed on the inner surface of the inner lining material 7 as a skin-contact layer. When the pilot wears the helmet, the skin-contact layer is in close contact with the wearer's head, which can effectively absorb and help wick away the wearer's sweat, keeping the wearer dry and comfortable.

[0025] The helmet body 2 has pre-drilled mounting positions for the earcups 3 on both sides corresponding to the wearer's ears. Figure 1 At the position indicated by the dotted line, the inner lining material 7 has a recessed cavity that matches the size of the headphone cover 3, which serves as a blind groove for assembly, so that the headphone cover 3 can be assembled at this cavity position.

[0026] To facilitate the demonstration of the headphone cover 3 assembled in the helmet body 2, Figure 2 On the right side of the helmet body 2, corresponding to the position of the headphone cover 3, the outer shell 4 is removed to show the style of the headphone cover 3 and its position in the inner lining 7.

[0027] like Figure 2 and Figure 3As shown, the headphone cover 3 is composed of a leather shell 5 and a soft inner lining. The leather shell 5 is bowl-shaped, and an outer edge 9 is formed at the rim of the bowl. The outer surface of the outer edge 9 serves as the contact area of ​​the headphone cover 3, that is, the side that contacts the pilot's face. Similar to the structure of similar headphone covers in the prior art, a soft inner lining is formed on the inner side of the leather shell 5. This soft inner lining can be used to maintain the shape of the leather shell 5, improve wearing comfort, and isolate external noise.

[0028] In different embodiments, the soft liner can be sound-absorbing foam, an inflatable air cushion, or a combination of both. When using sound-absorbing foam, a high-density sound-absorbing foam with a density range of 25–30 kg / m³ can be selected. This type of foam has excellent sound absorption performance and good resilience, effectively isolating external noise while ensuring pilot comfort, providing a quieter auditory environment for the pilot. When the soft liner uses an inflatable air cushion, the internal pressure of the air cushion can be adjusted to adapt to different pilot face shapes, improving the fit between the headset and the pilot's face, and further isolating external noise.

[0029] The earphone cover 3 has a depth to accommodate the wearer's ear in a bowl-shaped cavity while reserving a space for a accommodating compartment 8. The two sides of the accommodating compartment 8 have soft lining to protect the contents placed in the accommodating compartment 8.

[0030] The pilot helmet incorporates a bone conduction unit within the earcup 3. This unit comprises a sensing unit and a main unit 6. The sensing unit is molded onto the surface of the outer edge 9 of the helmet shell 5, corresponding to the side of the body that it contacts. In different embodiments, the sensing unit can be positioned anywhere on the outer edge 9 corresponding to the side of the body that it contacts, but it is preferably positioned on the outer edge 9 corresponding to the cheekbone or behind the ear. These two locations have fixed skull structures and are areas with good sound conduction, ensuring the accuracy and stability of sound information acquisition. The main unit 6 is detachably mounted within the accommodating layer 8 of the earcup 3 and communicates with the sensing unit via a built-in connector cable. The main unit is powered by a built-in lithium battery or a power supply connected to the pilot helmet to ensure the continuity and stability of the bone conduction function.

[0031] In this embodiment, the outer edge 9 of the shell 5 is formed with anti-slip texture, while the corresponding sensing part of the bone conduction unit is formed with a silicone adhesive layer. The combination of the two can increase the fit and comfort of the earphone cover 3 to the human body.

[0032] In addition, the bone conduction unit host 6 has recording and bone voiceprint functions. It can be removed from the housing layer 8 after being separated from the sensing unit to provide confidentiality. It also facilitates maintenance and data backup.

[0033] In this embodiment, to enable the bone conduction unit host 6 to be detachable within the accommodating layer 8 and to ensure optimal positional stability of the bone conduction unit host 6 after assembly in the accommodating layer 8, the bone conduction unit host 6 has a Velcro fastener formed on its back side, and the inner liner 7 has a Velcro fastener formed on the bottom surface of the corresponding mounting blind slot. Simultaneously, the earphone cover 3 has a pad 10 formed in the middle of the back cover 5, with Velcro fasteners formed on both sides of the pad 10. The pad 10 secures the bone conduction unit host 6 placed in the accommodating layer 8 on its inner surface using the Velcro fasteners, while on its outer surface, the earphone cover 3 is entirely fixed to the mounting blind slot of the inner liner 7 using the Velcro fasteners. This design facilitates the replacement and maintenance of the earphone cover 3, and also allows pilots to adjust the position and angle of the earphone cover 3 and replace it with earphone covers of different sizes according to their individual needs.

[0034] In practical use, when the pilot wears the helmet, the soft lining of the earcups 3 fits snugly around the pilot's ears, isolating them from external noise. At the same time, the bone conduction unit converts sound into vibrations through its sensing components, transmitting them directly to the pilot's inner ear through the skull, allowing the pilot to clearly receive sound information even in noisy flight environments.

[0035] In summary, the pilot helmet with bone conduction structure proposed in this embodiment effectively solves the problem of poor sound conduction in noisy environments by integrating bone conduction technology and pilot helmet design, thereby improving the pilot's communication experience and information interaction efficiency, and further ensuring flight safety.

Furthermore, it should be understood that after reading the technical content of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
