Description

Technical Field

[0001] This utility model relates to the field of cycling helmet technology, and in particular to a lightweight cycling helmet with a ventilation structure. Background Technology

[0002] Lightweight cycling helmets with ventilation systems are designed for cycling enthusiasts, combining protection, ventilation, and portability. Their core function is to withstand external impacts through the helmet's impact-resistant structure, while the ventilation system allows airflow to reduce head temperature. They also utilize lightweight materials and a flexible adjustment mechanism to fit different head sizes and reduce the burden of wearing them. These helmets are widely used for daily commuting, road cycling, and mountain biking, and are especially suitable for summer or long rides, effectively solving the problem of overheating associated with traditional helmets and improving riding comfort while ensuring safety. However, existing cycling helmets with ventilation functions have significant shortcomings in practical use.

[0003] On the one hand, ventilation is poor and controllable. Traditional ventilated helmets mostly use fixed ventilation holes, and the ventilation volume cannot be adjusted according to the ambient temperature. Moreover, the ventilation path is short, which can only achieve local heat dissipation. After riding for a long time, the head still feels stuffy. Some helmets have excessively large ventilation holes, which can also weaken the strength of the outer helmet structure and reduce its impact resistance during impact.

[0004] On the other hand, traditional helmets suffer from insufficient adaptability and lack of additional functions. Their adjustment structure is simple and relies heavily on the tightness of the straps. Some users experience pressure on their forehead or back of the head after wearing them, making it difficult to balance comfort and functionality. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a lightweight cycling helmet with a ventilation structure, which overcomes the shortcomings of the prior art and effectively solves the problems of poor ventilation, low controllability, insufficient adaptability and lack of additional functions in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A lightweight cycling helmet with a ventilation structure includes an outer helmet. A ventilation component is connected to the upper front of the outer helmet. The ventilation component includes a ventilation shell, sealing blocks slidably connected to both sides inside the ventilation shell, and levers welded and fixed to the front of the two sealing blocks on opposite sides. A fastening ring is connected to the inner wall of the outer helmet. A connecting ring is welded and fixed to the top of the fastening ring. A support ring is welded and fixed to the annular inner wall of the connecting ring. A protective pad is provided on the top of the support ring. An adjustment component is provided at the bottom of the support ring. The adjustment component includes a shock-absorbing pad, a headband sewn to the bottom of the shock-absorbing pad, an adjustment rope inserted into the headband, and fastening buckles snapped to both ends of the adjustment rope. Furthermore, the bottom sides of the outer helmet are connected with straps, and the bottom ends of the two straps are connected and fixed by a buckle.

[0007] The straps are made of highly elastic nylon and feature quick-release and micro-adjustment buckles to help secure the helmet and prevent it from shifting during rides. They also work with the adjustment components to fit different head sizes and improve wearing stability. Furthermore, both sides of the outer wall of the helmet are rotatably connected with buckles, and both buckles are secured with goggles.

[0008] The buckle is made of ABS engineering plastic and can rotate, making it easy to quickly install and remove the goggles and adjust the angle. The goggles use PC anti-fog lenses to protect against ultraviolet rays and prevent strong light or sand from irritating the eyes while riding, thus improving riding safety. Furthermore, the outer helmet has an opening at the upper front end, and the inner walls of the opening are bonded and fixed to the outer walls of the ventilation shell. The ventilation shell has an air inlet on the front, and slots that interlock with the sealing block are provided on the inner walls of both sides of the air inlet.

[0009] The opening provides a mounting base for the ventilation housing, which is made of PC material. The air inlet can introduce external airflow. The sealing block slides along the slot, which can adjust the opening size of the air inlet to achieve controllable ventilation and adapt to different temperature environments. Furthermore, the front of the support ring is provided with an insertion port, and a ventilation pipe is inserted into the insertion port, with one end of the ventilation pipe connected to the ventilation shell.

[0010] The ventilation duct uses a silicone flexible tube, which can guide the airflow introduced by the ventilation shell into the inside of the support ring, and then disperse it to the surrounding area of ​​the head through the hollow structure of the support ring, forming a complete ventilation path and improving heat dissipation efficiency. Furthermore, the shock-absorbing pad is composed of polyester fabric and internally filled with imitation silk cotton.

[0011] Polyester fabric has good breathability and abrasion resistance, and the inner filling of imitation silk cotton is elastic, which can cushion the vibration of bumpy roads, reduce the contact pressure between the head and the headband, and improve the comfort of wearing it for a long time. Furthermore, both ends of the adjusting rope are engaged with limit blocks, and the volume of the limit blocks is larger than the buckle eye.

[0012] The adjusting rope is made of high-strength polyester rope, and the tightness of the headband can be adjusted by pulling both ends; the limit block can prevent the adjusting rope from falling out of the fastening buckle, ensuring the stability of the adjusting structure, and the fastening buckle can lock the length of the adjusting rope to prevent loosening.

[0013] The beneficial effects of this utility model are as follows: With excellent and controllable ventilation, balancing safety and comfort, this helmet solves the problems of poor ventilation and low controllability of traditional helmets through adjustable ventilation components and a complete ventilation path. The air inlet of the ventilation shell, together with the sliding adjustment of the sealing block, allows the ventilation volume to be flexibly controlled according to the ambient temperature. In low temperatures, the ventilation holes are closed to prevent air from rushing in, while in high temperatures, the ventilation holes are fully opened. The ventilation tubes guide the airflow around the head to form all-area heat dissipation. During long rides, the head temperature is lower than that of traditional helmets, and the stuffiness is significantly reduced. At the same time, the outer helmet is made of high-strength PC material, and the ventilation structure does not compromise the impact resistance, ensuring safety. With its strong adaptability and comprehensive functions, this helmet enhances the user experience. Relying on multi-dimensional adjustment and integrated design, it improves upon the poor fit and lack of functions of traditional helmets. The adjustment rope and headband are designed to fit different head circumferences, and the straps and buckles provide additional fixation, ensuring comfortable wear for users with different head circumferences. The shock-absorbing pad's imitation silk cotton cushions vibrations, eliminating noticeable head vibrations on bumpy roads. The integrated goggles protect against strong light and sandstorms, eliminating the need for additional goggles. The swivel design allows for quick and easy adjustment. Its comprehensive functions are an improvement over traditional helmets, meeting diverse riding needs. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example:

[0017] Reference Figure 1-4A lightweight cycling helmet with a ventilation structure includes an outer helmet 1. A ventilation component 6 is connected to the upper front of the outer helmet 1. The ventilation component 6 includes a ventilation shell 7, sealing blocks 8 slidably connected to both sides inside the ventilation shell 7, and lever blocks 9 welded and fixed to the front of the two sealing blocks 8 on opposite sides. A fastening ring 11 is connected to the inner wall of the outer helmet 1. A connecting ring 12 is welded and fixed to the top of the fastening ring 11. A support ring 14 is welded and fixed to the annular inner wall of the connecting ring 12. A protective pad 15 is provided on the top of the support ring 14. An adjustment component 16 is provided at the bottom of the support ring 14. The adjustment component 16 includes a shock-absorbing pad 17, a headband 18 sewn to the bottom of the shock-absorbing pad 17, an adjustment rope 19 inserted into the headband 18, and fastening buckles 21 snapped to both ends of the adjustment rope 19. Both sides of the bottom of the outer helmet 1 are connected to straps 2, and the bottom ends of the two straps 2 are connected and fixed by buckles 3. The straps 2 are made of high-elasticity nylon material. With the quick-fastening and fine-adjustment function of the buckles 3, they can help fix the helmet and prevent it from shifting when riding on bumps. At the same time, they work with the adjustment component 16 to adapt to different head sizes and improve wearing stability. Both sides of the outer wall of the outer helmet 1 are rotatably connected to buckles 4. Both buckles 4 are locked with goggles 5. The buckles 4 are made of ABS engineering plastic and can rotate 360°, which facilitates quick installation, removal and angle adjustment of the goggles 5. The goggles 5 are made of PC protective material. The fog lens can block ultraviolet rays and prevent strong light or sand from irritating the eyes while riding, thus improving riding safety. The upper front of the outer helmet 1 has an opening, and the inner walls of the opening are bonded and fixed to the outer walls of the ventilation shell 7. The front of the ventilation shell 7 has an air inlet 10, and the inner walls on both sides of the air inlet 10 have slots that fit into the sealing block 8. The opening provides a mounting base for the ventilation shell 7. The ventilation shell 7 is made of PC material, and the air inlet 10 can introduce external airflow. The sealing block 8 slides along the slot, which can adjust the opening and closing size of the air inlet 10 to achieve controllable ventilation and adapt to different temperature environments.

[0018] The front of the support ring 14 has an insertion port into which a ventilation pipe 13 is inserted. One end of the ventilation pipe 13 is connected to the ventilation shell 7. The ventilation pipe 13 is a silicone flexible tube, which can guide the airflow introduced by the ventilation shell 7 into the support ring 14, and then disperse it to the surrounding area through the hollow structure of the support ring 14, forming a complete ventilation path and improving heat dissipation efficiency. The shock-absorbing pad 17 is composed of polyester fabric and internal filling with imitation silk cotton. The polyester fabric has good breathability and wear resistance, and the internal filling with imitation silk cotton has an elastic recovery rate of ≥ 90% cushioning of vibrations from bumpy roads, while reducing the contact pressure between the head and the headband 18, improving comfort during long-term wear. Both ends of the adjustment rope 19 are secured with limit blocks 20. The volume of the limit blocks 20 is larger than the buckle eye of the fastening buckle 21. The adjustment rope 19 is made of high-strength polyester rope, and the tightness of the headband 18 can be adjusted by pulling both ends. The limit blocks 20 can prevent the adjustment rope 19 from falling out of the fastening buckle 21, ensuring the stability of the adjustment structure. The fastening buckle 21 can lock the length of the adjustment rope 19 to prevent loosening.

[0019] Regarding the outer helmet and basic protection: the outer helmet 1 is injection molded from high-strength PC material with a matte finish to avoid glare from direct sunlight. A 1mm thick EVA buffer strip is attached to the inner wall of the outer helmet 1 to cover key areas such as the forehead and temples, providing initial cushioning against impact. The connecting ears on both sides of the bottom of the outer helmet 1 are integrally formed and fixed to the strap 2 with rivets. The buckles 3 sewn at both ends of the strap 2 are plastic buckles. After fastening, the length can be finely adjusted by the adjustment slider on the female buckle to help fix the helmet. Regarding the goggles and buckles: The buckles 4 are welded to the outer walls of both sides of the outer helmet 1. The buckle 4 has an 8mm diameter slot in the middle, which engages with the buckles on both sides of the goggles 5. The insertion and extraction force is ≤15N, and it can be easily installed and removed by a single person. The lenses of the goggles 5 are treated with PC anti-fog coating, and the anti-fog effect lasts for ≥8 hours. The frame is made of TPU elastic material, which can be slightly deformed to adapt to different facial contours. The temples are wrapped with 5mm thick silicone pads, so there is no pressure when wearing them. The goggles 5 can be rotated upwards to the top of the outer helmet 1 for storage without affecting the field of vision. Regarding the ventilation components and ventilation tubes: The opening at the top front of the outer helmet 1 is coated with strong adhesive around its inner walls and is bonded and fixed to the ventilation shell 7. The air inlets 10 on the front of the ventilation shell 7 have slots on the inner walls on both sides of each air inlet 10 that are inserted into the sealing block 8. The lever 9 on the front of the sealing block 8 protrudes from the surface of the ventilation shell 7, making it easy to push and adjust with your fingers. The insertion port on the front of the support ring 14 is inserted into the ventilation tube 13. The other end of the ventilation tube 13 is connected to the air outlet of the ventilation shell 7 through a pagoda connector to ensure no airflow leakage. The ventilation tube 13 can bend slightly with head movement without affecting wearing comfort. For the fastening ring and the support ring: The fastening ring 11, which is bonded to the inner wall of the outer helmet 1, is fixed to the connecting ring 12 by ultrasonic welding. The support ring 14 is welded to the inner wall of the connecting ring 12. The surface of the support ring 14 has evenly distributed perforations with a perforation rate of 30%, which facilitates airflow dispersion and heat dissipation. The protective pad 15, which is bonded to the top of the support ring 14, covers the area where the support ring 14 contacts the head, reducing local pressure. The surface of the protective pad 15 has anti-slip textures to prevent the helmet from sliding.

[0020] Regarding the adjustment components: the shock-absorbing pad 17 sewn to the bottom of the support ring 14 is made of polyester fabric and is sewn to the headband 18. The adjustment rope 19 is inserted inside the headband 18. The two ends of the adjustment rope 19 pass through the metal ring at the end of the headband 18 and are locked to the limiting block 20. The diameter of the limiting block 20 is larger than the buttonhole of the fastening buckle 21 to prevent the adjustment rope 19 from falling off. The fastening buckle 21 is a plastic D-ring. By adjusting the position of the adjustment rope 19 in the buttonhole, the circumference of the headband 18 can be continuously adjusted from 52 to 64 cm. After locking, there is no looseness, which can accommodate users with different head circumferences.

[0021] Working principle: Helmet wearing and fitting adjustment: Before wearing, adjust the adjustment component 16 according to the head circumference: pull both ends of the adjustment rope 19 to make the circumference of the headband 18 fit the head size (insert 2 fingers without pressure), fasten the buckle 21 to lock the adjustment rope 19, and ensure that the headband 18 fits the head tightly but not tightly; put the helmet on from the top of the head downwards, so that the protective pad 15 on the top of the support ring 14 fits the forehead and back of the head, fasten the bottom buckle 3, and fine adjust the length of the strap 2 to ensure that the helmet does not wobble from side to side (wobble amplitude ≤3mm), and complete the basic fitting.

[0022] Ventilation Adjustment and Daily Riding: Adjust ventilation according to ambient temperature: In hot weather (≥25℃), push the lever 9 with your finger to slide the sealing block 8 along the slot to both sides, fully opening the air inlet 10. External airflow enters the ventilation shell 7 through the air inlet 10, is guided through the ventilation tube 13 to the support ring 14, and then disperses to the area around the head through the hollow holes of the support ring 14, carrying away heat and achieving full-area heat dissipation; In cold weather (≤15℃), push the lever 9 to close the air inlet 10 with the sealing block 8 to prevent cold air from entering and maintain head temperature. When riding, if you encounter strong light or sandstorms, lower the goggles 5 from the top of the outer helmet 1 and adjust the angle to a clear view using the buckle 4. The anti-fog lens of the goggles 5 resists strong light and sandstorms, ensuring visual safety; When riding on bumpy roads, the imitation silk cotton of the shock-absorbing pad 17 cushions the vibration, and there is no obvious vibration in the head, improving comfort.

[0023] Impact protection and functional storage: In the event of an impact, the PC material of the outer helmet 1 first resists the external impact force, and disperses the impact force initially through its own deformation (30%). The EVA buffer strip on the inner wall further absorbs the impact (20%). The support ring 14 and the protective pad 15 work together to evenly transfer the remaining impact force to the area around the head, avoiding excessive local force. At the same time, the elastic material of the shock-absorbing pad 17 buffers the contact force between the head and the helmet, reducing the risk of injury. After riding, the goggles 5 can be rotated upwards to the top of the outer helmet 1 for storage. The buckle 3 and fastening buckle 21 can be released to remove the helmet. If cleaning is required, the ventilation tube 13 can be pulled out to clean the goggles 5 and the shock-absorbing pad 17 separately (the shock-absorbing pad 17 is washable and can be reassembled after drying), making maintenance convenient. Adaptable to Special Scenarios: The functions can be flexibly adjusted for different cycling scenarios: When cycling on the road, the ventilation holes can be fully opened and the goggles 5 can be lowered to ensure heat dissipation and clear vision; when cycling in the mountains, some ventilation holes can be closed (leaving 50% ventilation) to prevent branches from scratching the face, while the goggles 5 can be kept lowered to protect against gravel; when commuting for short distances, the goggles 5 can be removed and the ventilation holes closed to simplify equipment while ensuring basic protection. The whole process achieves controllable ventilation, flexible adaptation, and comprehensive cycling protection to meet the needs of different scenarios.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
