Description

Technical Field

[0001] This invention relates to the field of helmet technology, and in particular to a smart helmet with shoulder and neck heat dissipation assistance. Background Technology

[0002] With the widespread application of smart helmets in cycling, industrial operations, firefighting, outdoor sports, and virtual reality, users' demands for comfort during extended wear are increasing. Although existing smart helmets generally integrate head cooling functions (such as fans in the top or back of the head area), their heat dissipation efforts are mostly concentrated on the top or back of the head, while heat management in the shoulder and neck area is often neglected. In actual use, the wearer's shoulder and neck area (including the back of the neck, upper trapezius muscles, and collar area) easily accumulates heat and sweat due to factors such as being close to the bottom edge of the helmet, being covered by clothing, and being exposed to direct sunlight. Especially in high-temperature, high-humidity, or high-intensity work environments, localized stuffiness, stickiness, discomfort, and even prickly heat and skin irritation often occur, seriously affecting the wearing experience and work efficiency.

[0003] Therefore, there is an urgent need for a smart helmet structure that can integrate a directional ventilation mechanism into the helmet body and guide airflow to the wearer's shoulder and neck area to solve the technical problems of insufficient heat dissipation and poor comfort in the existing technology. Summary of the Invention

[0004] This invention proposes a smart helmet with shoulder and neck heat dissipation assistance, aiming to solve the technical problems of insufficient shoulder and neck heat dissipation and poor comfort in the prior art.

[0005] To achieve the above objectives, the present invention proposes a shoulder and neck assisted heat dissipation smart helmet, which includes a helmet body and an exhaust fan. The exhaust fan is located at the rear of the helmet body and has a first air outlet. The orientation of the first air outlet is configured to directly guide airflow to the wearer's shoulder and neck area when the helmet is worn, so as to actively dissipate heat from the shoulder and neck area.

The air outlet channel connects the first air outlet and the second air outlet, and the second air outlet faces downwards from the helmet body to direct airflow to the wearer's shoulder and neck area.

[0007] In one embodiment, the air outlet duct includes a main duct and two branch ducts, the main duct being connected to the first air outlet; the ends of the two branch ducts respectively form two second air outlets facing the left shoulder and the right shoulder.

[0008] In one embodiment, each of the second air outlets includes a plurality of spaced-apart strips.

[0009] In one embodiment, the width of the slot is 0.9 mm to 1.5 mm.

[0010] In one embodiment, the cross-section of the strip-shaped opening along the airflow outflow direction is expanded.

[0011] In one embodiment, downward protrusions are formed on both sides of the lower end of the helmet body, and the two second air vents are located on the corresponding protrusions.

[0012] In one embodiment, the helmet body is provided with an air duct and an air inlet, the air duct connects the air inlet and the air inlet of the exhaust fan, and the air inlet connects the inner cavity of the helmet body and the air duct.

[0013] In one embodiment, the air duct extends from the top of the helmet body toward the rear end of the helmet body; the exhaust fan is installed at the end of the air duct.

[0014] In one embodiment, the helmet body is further provided with a ventilation opening, which connects the inner cavity of the helmet body to the outside.

[0028] This invention proposes a smart helmet with shoulder and neck heat dissipation assistance.

[0029] Please see Figures 1 to 6In one embodiment of the present invention, the shoulder and neck auxiliary heat dissipation type smart helmet includes a helmet body 10 and an exhaust fan 20; the exhaust fan 20 is located at the rear of the helmet body 10, and the exhaust fan 20 has a first air outlet 21. The orientation of the first air outlet 21 is configured to directly guide the airflow to the wearer's shoulder and neck area when the helmet is worn, so as to actively dissipate heat from the shoulder and neck area.

[0030] Specifically, the smart helmet includes a helmet body 10 and a fan 20. The fan 20 is installed at the rear of the helmet body 10, specifically embedded inside the back of the helmet shell or fixed to the rear side of the lower edge of the helmet, positioned adjacent to the area above the wearer's neck. The fan 20 has a first air outlet 21, the orientation of which is specifically configured: when the helmet is worn normally, its airflow axis points directly towards the wearer's shoulder and neck area (including the skin of the back of the neck, the upper edge of the trapezius muscle, and the area covered by the collar), rather than radiating directly backward or upward.

[0031] The rear mounting position of the exhaust fan 20 naturally places it close to the beginning of the shoulder and neck, shortening the airflow delivery path; the directional orientation of the first air outlet 21 ensures that the exhaust airflow can directly act on the target heat dissipation area without the need for an additional air guide structure; the combination of the two allows the exhaust fan 20 to not only perform the function of exhausting hot air from inside the helmet, but also to have the dual function of external active air supply to cool the shoulder and neck - that is, while extracting the hot and humid air from inside the helmet, it precisely delivers a portion of the airflow (or independent airflow) to the surface of the shoulder and neck, forming local forced convection.

[0032] This application can specifically alleviate the stuffiness of the shoulders and neck. The airflow directly blows on the shoulders and neck area, which is prone to sweating and poor ventilation, accelerating sweat evaporation and effectively reducing the local body temperature. This solves the comfort imbalance problem of traditional helmets where the head is cool and the neck is hot. Whether cycling, walking or working at rest, it can actively provide cooling for the shoulders and neck without relying on external airflow, making it widely applicable. As one of the heat-sensitive areas of the human body, effective cooling of the shoulders and neck can significantly improve the tolerance for long-term wear and the user experience.

[0033] In summary, by placing the exhaust fan 20 at the rear of the helmet and configuring its first air outlet 21 to directly guide the air to the shoulder and neck area, this invention breaks through the limitation of traditional helmets that only focus on head heat dissipation, and realizes integrated active thermal management of the head and neck. Under the premise of simple structure, it significantly improves the ergonomic performance and practical value of smart helmets.

[0034] Furthermore, the helmet body 10 is provided with an air outlet 11 and a second air outlet 12. The air outlet 11 connects the first air outlet 21 and the second air outlet 12. The second air outlet 12 faces downward of the helmet body 10 and is used to guide airflow to the wearer's shoulder and neck area.

[0035] Specifically, in the shoulder and neck assisted heat dissipation smart helmet of the present invention, in order to achieve precise control and efficient guidance of airflow path, the helmet body 10 further integrates an air outlet channel 11, and a second air outlet 12 is provided in its lower region. One end of the air outlet channel 11 is connected to the first air outlet 21 of the exhaust fan 20, and the other end is connected to the second air outlet 12, forming a directional airflow path from the exhaust fan 20 to the outside of the helmet. The second air outlet 12 is configured to face downwards towards the helmet body 10. When the helmet is worn normally, its airflow is directly projected onto the back of the wearer's neck and upper shoulder area, achieving active cooling of the shoulder and neck area.

[0036] The exhaust fan 20 serves as the airflow power source, and through its first air outlet 21, it discharges airflow (which may be extracted internal hot air or independent circulating airflow) into the air outlet channel 11. The air outlet channel 11 serves as an internal airflow guiding structure, extending downward along the inner wall of the helmet's rear shell. Its cross-sectional shape and direction have been optimized by fluid dynamics to ensure that the airflow is transmitted to the lower edge of the helmet with low resistance and low noise. The second air outlet 12 serves as the terminal outlet, and its downward arrangement direction matches the anatomical contour of the human shoulder and neck, so that the airflow can naturally cover the skin of the back of the neck, the collar gap, and the upper edge of the trapezius muscle, which are prone to heat accumulation, after leaving the helmet.

[0037] This application enables precise directional airflow, enhancing heat dissipation. The airflow is constrained and guided to the downward-facing second air outlet 12 via the air outlet channel 11, preventing disordered airflow diffusion at the rear of the helmet and ensuring concentrated airflow to the target area of ​​the shoulders and neck. The channel-type airflow reduces turbulence loss, allowing the airflow to maintain high momentum as it leaves the second air outlet 12, enabling it to penetrate clothing gaps or cover a wider area of ​​the shoulders and neck. The airflow flows within a closed channel, avoiding the high-frequency whistling sound of a direct fan blow. Simultaneously, the airflow direction avoids the sensitive area at the back of the head, preventing localized overcooling and improving comfort. The air outlet channel 11 is embedded inside the helmet shell, and the second air outlet 12 can be hidden in the lower edge decorative seam or grille, without affecting the overall shape and aerodynamic performance.

[0038] In summary, by setting up an air outlet channel 11 that connects the first air outlet 21 and the downward-facing second air outlet 12, the present invention achieves controllable, efficient, and quiet guidance of airflow for cooling the shoulders and neck, significantly improving the thermal management capability of the smart helmet in long-term wearing scenarios.

[0039] Furthermore, the air outlet duct includes a main duct 111 and two branch ducts 112. The main duct 111 is connected to the first air outlet 21. The ends of the two branch ducts 112 respectively form two second air outlets 12 facing the left shoulder and the right shoulder.

[0040] Specifically, in the shoulder and neck assisted heat dissipation smart helmet of the present invention, in order to achieve balanced and efficient cooling of both shoulder and neck areas, the air outlet channel 11 built into the helmet body 10 adopts a bifurcated structure design, specifically including a main channel 111 and two branch channels 112. The upstream end of the main channel 111 is directly connected to the first air outlet 21 of the exhaust fan 20 to receive the airflow discharged by the exhaust fan 20; the main channel 111 extends towards the lower edge of the helmet and bifurcates into two independent branch channels 112 at its end, extending downwards along the left and right sides of the helmet's rear shell respectively; the ends of the two branch channels 112 each form a second air outlet 12, and the orientation of these two second air outlets 12 is respectively configured to point towards the wearer's left and right shoulder areas.

[0041] In this embodiment, the airflow generated by the exhaust fan 20 first enters the main duct 111, which serves as the central hub for airflow distribution. The main channel 111 branches symmetrically to equally direct airflow into the left and right branch channels 112, ensuring balanced airflow to both sides of the shoulders and neck. Each branch channel 112 extends along the rear side profile of the helmet, with its second air outlet 12 precisely targeting areas prone to heat accumulation, such as the upper edge of the trapezius muscle, the junction of the neck and shoulder, and the area covered by the collar, achieving simultaneous active heat dissipation on both sides. The entire channel system (main channel 111 + branch channel 112) is embedded inside the helmet shell, forming a closed airflow path to prevent airflow leakage or disturbance during transmission.

[0042] This solution achieves symmetrical and balanced shoulder cooling through independent left and right branch channels 112, improving the overall wearing experience. The enclosed main channel 111 and branch channels 112 reduce energy loss and ensure that the airflow output from the exhaust fan 20 is efficiently delivered to the target area, avoiding ineffective diffusion. The branch channel 112 conforms to the curved surface of the rear of the helmet, and the angle of the second air outlet 12 is optimized by ergonomics, so that the airflow naturally covers the high-heat area of ​​the shoulders without requiring the user to adjust their posture. After being buffered by the channels, the airflow is gently blown out from the side air outlets at a moderate speed, avoiding discomfort caused by concentrated direct blowing, while improving the efficiency of sweat evaporation. The channels are built into the shell sandwich or between the reinforcing ribs, without weakening the helmet's impact resistance structure, and the appearance is simple with no exposed air ducts.

[0043] In summary, by setting up a bifurcated air outlet channel 11 consisting of a main channel 111 and left and right branch channels 112, and forming second air outlets 12 at the ends of the branch channels 112 facing the left and right shoulders respectively, the present invention achieves full coverage of the shoulder and neck area, balanced air supply and efficient heat dissipation, effectively solving existing technical problems such as insufficient heat dissipation on one side, airflow waste and comfort imbalance, and significantly improving the thermal management performance and human-machine adaptability of smart helmets in long-term use scenarios.

[0044] Furthermore, each of the second air outlets 12 includes a plurality of spaced-apart strip-shaped outlets 121.

[0045] Specifically, in the shoulder and neck assisted heat dissipation smart helmet of the present invention, in order to further optimize airflow distribution and wearing comfort, each second air outlet 12 is not a single opening, but is composed of multiple strip-shaped openings 121 arranged horizontally or diagonally at intervals. Specifically, the second air outlet 12 located at the end of the left branch 112 includes several parallel strip-shaped openings 121, and the second air outlet 12 at the end of the right branch 112 also adopts the same structure; an appropriate spacing is maintained between each strip-shaped opening 121 to form an array-type air outlet layout.

[0046] The design of the strip-shaped opening 121 array has a close functional synergy with the air outlet 11 and the shoulder and neck heat dissipation requirements. When the airflow delivered from the branch duct 112 arrives at the second air outlet 12, it is distributed to multiple strip-shaped openings 121 for simultaneous discharge, thus dispersing the originally concentrated airflow into multiple fine streams. The extension direction of the strip-shaped openings 121 can be arranged obliquely along the shoulder contour (such as the outer side being higher than the inner side), so that the airflow is more in line with the curved surface direction of the upper edge of the trapezius muscle. The interval area between each strip-shaped opening 121 retains the helmet shell material, which maintains the local structural strength and avoids foreign object intrusion or rough appearance due to large-area openings.

[0047] This application can expand the heat dissipation coverage area. Multiple strip-shaped openings 121 form a horizontal or fan-shaped airflow band, effectively covering a wide area from the middle of the back of the neck to the left and right acromions, avoiding the problem of "point cooling" caused by single-hole air outlets while the surrounding area remains hot; it improves the uniformity and gentleness of airflow, disperses the airflow to reduce local wind speed peaks, reduces the stinging sensation of direct airflow, and enhances the overall evaporative cooling effect through the superposition of multiple airflows, achieving "wide-area breeze" style comfortable heat dissipation; compared with large circular or square openings, the narrow strip-shaped openings 121 can weaken the vortex shedding frequency, reduce high-frequency aerodynamic noise, and improve quietness performance; the rib structure retained between the strip-shaped openings 121 enhances the rigidity of the lower edge of the helmet, meeting the impact resistance safety requirements; at the same time, the regularly arranged strip grilles can be used as a design element to enhance the product's appearance and texture; the narrow openings are not easily blocked by hair, fabric, or fingers, and the small gaps can prevent larger particulate pollutants from entering the air duct 14.

[0048] In summary, by designing each second air outlet 12 as multiple spaced strip-shaped outlets 121, this invention achieves a wider, more uniform, softer, and quieter shoulder and neck heat dissipation effect without increasing fan power, while taking into account structural reliability and industrial design requirements. It is a key detail innovation that improves the ergonomics and user experience of smart helmets.

[0049] Furthermore, the width of the strip opening 121 is 0.9 mm to 1.5 mm.

[0050] Specifically, in the shoulder and neck assisted heat dissipation smart helmet of the present invention, the width of each of the multiple strip-shaped openings 121 included in the second air outlet 12 is strictly limited to the range of 0.9mm to 1.5mm. This size range is the result of comprehensive optimization based on multiple dimensions such as airflow performance, safety protection, manufacturing process, and user experience.

[0051] This width parameter is closely coordinated with the overall design of the air outlet 11, fan performance, and human wearing requirements. If the width of the strip opening 121 is less than 0.9mm, the flow resistance will increase significantly. Under the condition that the power of the exhaust fan 20 is limited (usually 3-8W), the effective air volume will drop sharply, making it difficult to achieve substantial cooling of the shoulder and neck area. At the same time, the opening that is too narrow is easily blocked by sweat, dander, or fine fibers, affecting long-term reliability. If the width is greater than 1.5mm, although it can increase the ventilation volume, it will bring multiple risks: on the one hand, the opening is too large and the user's fingers or foreign objects may accidentally enter the air duct 14, interfering with the internal structure or causing safety hazards; on the other hand, the wide gap will weaken the local shell strength of the lower edge of the helmet and increase the risk of external dust and rainwater seeping in along the gap. Controlling the width between 0.9mm and 1.5mm can ensure sufficient flow cross-sectional area while taking into account low resistance, anti-clogging, safety, and structural integrity. This allows the airflow to blow evenly on the shoulder and neck skin at a moderate speed, achieving efficient evaporative cooling without producing a stinging sensation.

[0052] The resulting technical effects include: Optimized airflow and airflow balance: Within this width range, the airflow speed is moderate (usually 1–3 m / s), which can effectively promote sweat evaporation while avoiding the discomfort caused by high-speed direct airflow, achieving a "gentle yet effective" cooling experience; Significantly improves anti-clogging performance: Widths of 0.9mm or more can reduce the probability of particle clogging, while widths of 1.5mm or less effectively prevent hair (single diameter of about 0.05–0.1mm, but easy to clump together) and fabric fibers from penetrating the air duct 14; Enhanced structural safety: The width of the ribs retained between the 121 slots is guaranteed (usually ≥1.5 mm), ensuring that the lower edge of the helmet meets the impact resistance and stiffness requirements (such as EN1078, GB24429 and other standards). Therefore, by limiting the width of the strip opening 121 to the range of 0.9mm to 1.5mm, the present invention achieves the best balance of heat dissipation performance, safety of use, structural reliability and manufacturing feasibility in a limited space, which is a factor in ensuring the stable, comfortable and long-lasting operation of the shoulder and neck auxiliary heat dissipation function.

[0053] Furthermore, the cross-section of the strip-shaped opening 121 along the airflow outflow direction is expanded.

[0054] Specifically, in the shoulder and neck assisted heat dissipation smart helmet of the present invention, in order to further optimize the diffusion characteristics and comfort of the exhaust airflow, each strip-shaped opening 121 has an expanded cross-section along the airflow outflow direction (i.e., from the inside of the air duct 14 to the outside shoulder and neck area). The inlet end of the strip-shaped opening 121 inside the helmet shell is narrower, while the outlet end facing the outside is slightly wider, forming a slightly inclined trumpet-shaped or wedge-shaped channel. Its expansion angle is usually controlled within the range of 3° to 10° to balance fluid performance and structural feasibility.

[0055] The expanded cross-section design has a clear functional synergy with the air outlet 11, the exhaust fan 20, and the shoulder and neck heat dissipation target. The airflow generated by the exhaust fan 20 is delivered to the inlet of the strip opening 121 through the main channel 111 and the branch channel 112, and has a certain dynamic pressure. When the airflow passes through the strip opening 121 with a gradually expanding cross-section, the flow velocity decreases moderately and the static pressure rises slightly, causing the airflow to naturally diffuse outward after leaving the outlet, forming a fan-shaped air curtain with a larger coverage area. This diffusion effect allows the airflow that was originally concentrated in the center of the slit to spread laterally and more evenly cover the irregular curved areas such as the upper edge of the trapezius muscle, the two sides of the back of the neck, and the edge of the collar.

[0056] The expanding strip-shaped inlet 121 of this application makes the exhaust airflow slightly divergent. The cooling range of a single strip-shaped inlet 121 is significantly larger than that of a straight through slit of equal width, reducing the number of openings required and simplifying the structure. The flow velocity decreases gradually at the outlet, avoiding local stinging or "cold shock" sensations caused by high-speed jets, and achieving a more natural cooling effect. The gradually expanding structure suppresses sudden expansion and vortex shedding of the airflow at the outlet edge, reducing high-frequency aerodynamic noise and improving operational quietness.

[0057] Furthermore, the lower end of the helmet body 10 has downward protrusions 13 on both sides, and the two second air vents 12 are located on the corresponding protrusions 13.

[0058] Specifically, in the shoulder and neck assisted heat dissipation smart helmet of the present invention, in order to optimize the air outlet position and airflow projection efficiency, the lower left and right sides of the helmet body 10 are respectively formed with downward protruding protrusions 13. These two protrusions 13 are symmetrically arranged along the lower rear edge of the helmet, and their shape follows the natural extension of the human shoulder and neck contour; two second air outlets 12 are respectively integrated on the corresponding protrusions 13, so that the position of the air outlets is closer to the wearer's left and right shoulder areas in space. Since the human shoulder is located below the lower edge of the helmet and slightly offset outward, traditional helmets with a flat lower edge cannot effectively deliver airflow to the shoulder-neck junction. By setting a downward protruding part 13, the second air outlet 12 can be closer to the shoulder skin surface in the vertical direction, while slightly expanding outward in the horizontal direction, so that its airflow axis is naturally aligned with the upper edge of the trapezius muscle and the collar coverage area. The protruding part 13 can accommodate the turning section at the end of the branch channel 112, so that the airflow is adjusted in direction before entering the second air outlet 12, reducing flow loss. The overall shape is integrated with the helmet's aerodynamics and aesthetic design, avoiding an abrupt external structure.

[0059] The solution proposed in this application can significantly shorten the air outlet distance and improve heat dissipation efficiency: the protrusion 13 extends or lowers the second air outlet 12 to a position closer to the shoulder, greatly reducing the airflow transmission gap, reducing airflow attenuation, and ensuring that the effective wind speed acts on the target area; the air outlet naturally expands outward with the protrusion 13, avoiding the airflow from being concentrated on the back of the neck center line, but instead covering the high heat generation areas of the left and right shoulders respectively, achieving balanced cooling on both sides; the air outlet is close to the curved surface of the shoulder, which is conducive to the airflow adhering to the skin surface, extending the heat exchange path, and improving the sweat evaporation efficiency; the protrusion 13, as a reinforced structure integrally formed by the shell, not only hides the air outlet, but also improves the rigidity of the lower edge of the helmet, meeting the impact safety standards (such as EN1078, DOT, etc.).

[0060] Furthermore, the helmet body 10 is provided with an air duct 14 and an air inlet 15. The air duct 14 connects the air inlet 15 and the air inlet 22 of the exhaust fan 20. The air inlet 15 connects the inner cavity of the helmet body 10 and the air duct 14.

[0061] Specifically, in the shoulder and neck assisted heat dissipation smart helmet of the present invention, in order to achieve efficient exhaust of hot and humid air inside the helmet, the helmet body 10 integrates an air duct 14 and an air inlet 15. The air inlet 15 is located on the inner surface of the helmet body 10 and directly connects the inner cavity of the helmet with the internal air duct 14. The air duct 14, as a closed airflow channel, is connected at one end to the air inlet 15 and at the other end to the air inlet 22 of the exhaust fan 20, thereby forming a complete negative pressure exhaust path from the inner cavity of the helmet → air inlet 15 → air duct 14 → exhaust fan 20. The air inlet 15 serves as an airflow collection port, located in high-heat areas such as the top or upper side of the helmet, to capture the hot and humid air accumulated near the wearer's scalp. The air duct 14 serves as the main airflow guide, smoothly delivering the air collected by the air inlet 15 along a preset path (such as a Y-shape or a single channel) to the exhaust fan 20 at the rear, preventing the airflow from spreading disorderly or short-circuiting within the shell cavity. The exhaust fan 20 serves as a power source, generating negative pressure at its air inlet 22 to drive the entire system to run continuously, ultimately exhausting the hot and humid air through the air outlet 11 to the shoulder and neck area or the external environment. The entire path is completely enclosed inside the helmet shell, ensuring that the airflow flows efficiently in the designed direction, unaffected by external interference.

[0062] This application can efficiently exhaust internal hot and humid air by setting up air duct 14: guided by the dedicated air duct 14, it avoids the randomness and inefficiency of traditional open-type passive ventilation and achieves active heat dissipation of "production and discharge at the same time". The enclosed air duct 14 reduces leakage and eddies, allowing the negative pressure of the exhaust fan 20 to be effectively transferred to the air inlet 15, ensuring continuous and stable airflow; the continuous exhaust of hot and humid air can reduce the humidity of the inner lining, reducing stuffiness and skin discomfort, especially suitable for long-term wear scenarios; it provides an airflow source for heat dissipation of the shoulders and neck: the exhaust hot air can be guided to the shoulder and neck area through the aforementioned air outlet duct 11, achieving the dual function of internal heat dissipation and external cooling.

[0063] In summary, by setting up a closed exhaust system within the helmet body 10 that connects the air inlet 15, the air duct 14, and the air inlet 22 of the exhaust fan 20, this invention constructs an efficient, controllable, and low-noise internal thermal management mechanism. This not only significantly improves head comfort but also provides a reliable airflow basis for auxiliary heat dissipation of the shoulders and neck, serving as the core structural support for achieving full-area thermal comfort in smart helmets.

[0064] Furthermore, the air duct 14 extends from the top of the helmet body 10 to the rear end of the helmet body 10; the exhaust fan 20 is installed at the end of the air duct 14.

[0065] Specifically, in the shoulder and neck assisted heat dissipation smart helmet of the present invention, a main air duct 14 is provided inside the helmet body 10. This air duct 14 starts at the top of the helmet body 10 and extends downwards and backwards along the inner contour of the helmet to the rear end of the helmet body 10. The exhaust fan 20 is fixedly installed at the end of the air duct 14 (i.e., near the lower rear edge of the helmet), with its air inlet 22 sealed to the outlet of the air duct 14, and its air outlet connected to the aforementioned air outlet channel 11 for shoulder and neck heat dissipation. This layout design reflects clear fluid path planning and ergonomic collaboration. The air duct 14 starts at the top of the head, making it easy to collect the hot and humid air generated by the hottest and most sweaty parts of the head (such as the top of the forehead and the area around the Baihui acupoint). The air duct 14 extends naturally backward along the shape of the head, conforming to the curvature of the skull, avoiding sharp bends or sudden expansion / contraction, and reducing flow resistance. The exhaust fan 20 is placed at the end (rear end) of the air duct 14, forming a unidirectional negative pressure flow field of "front-end air intake - full-process flow guidance - end suction", ensuring that the airflow flows stably from the high-heat area to the exhaust outlet, without backflow or dead corners. At the same time, the exhaust fan 20 is located at the rear of the helmet, and the airflow it exhausts can be directly connected to the air outlet 11 facing the shoulders and neck, realizing the integration of internal heat dissipation and external shoulder and neck cooling functions.

[0066] This application constructs an efficient unidirectional exhaust path through the design of the air duct 14. The straight line from the top to the rear, the low-resistance air duct 14, combined with the end suction, significantly improves the efficiency of removing hot and humid air and shortens the heat dissipation response time. The airflow flows from front to back along the head shape, covering multiple heat-generating areas such as the top, occiput, and temples, avoiding local heat accumulation; the end-mounted fan is located at the low-pressure end of the entire flow channel, which can more effectively establish negative pressure in the entire air duct 14 and avoid intake disturbance or efficiency loss caused by front-mounted installation; the end of the air duct 14 is tightly connected to the exhaust fan 20 and the air outlet duct 11, reducing the number of connecting parts and leakage points, and improving the system's sealing and reliability.

[0067] Therefore, by designing the air duct 14 to extend from the top of the head to the rear end and installing the exhaust fan 20 at the end of the air duct 14, the present invention achieves the unity of the shortest airflow path, the maximum exhaust efficiency and the integration of functional modules. It not only effectively solves the problem of heat and moisture accumulation inside the head, but also provides a stable airflow source and a reasonable spatial layout for active heat dissipation of the shoulders and neck. It is a key structural solution to improve the overall thermal management performance of smart helmets.

[0068] Furthermore, the helmet body 10 is also provided with a ventilation opening 16, which connects the inner cavity of the helmet body 10 to the outside.

[0069] Specifically, in the shoulder and neck assisted heat dissipation smart helmet of the present invention, in addition to an active ventilation system (including air duct 14, air inlet 15 and exhaust fan 20), the helmet body 10 is further provided with a ventilation opening 16. The ventilation opening 16 is a through hole or grid structure opened on the helmet shell, which directly connects the inner cavity of the helmet body 10 with the external environment, without passing through the air duct 14 or exhaust fan 20, forming a passive ventilation path.

[0070] When the exhaust fan 20 is running, a slight negative pressure is generated inside the helmet cavity. At this time, cooler outside air can flow naturally into the cavity through the vent 16 as a supplementary airflow to balance the pressure difference caused by active ventilation and prevent the wearer from experiencing ear stuffiness or discomfort from suction. When the exhaust fan 20 is not running or is running at low speed (such as short-term standstill or low power mode), the vent 16 can still achieve basic ventilation by relying on natural convection or the wind blowing in front of the rider, maintaining basic breathability. The vent 16 is usually located in the windward areas such as the forehead, top, or upper side of the helmet. Its position is offset from the air inlet 15 of the active system to avoid airflow short-circuiting (i.e., outside air is directly drawn out without heat exchange with the head), ensuring that the air entering the cavity can effectively participate in heat and moisture exchange before being discharged through the air duct 14.

Any equivalent structural transformations made based on the technical concept of the present invention and the contents of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present invention.
