Description

Technical Field

[0001] This utility model relates to the field of helmet technology, specifically to a full-face helmet. Background Technology

[0002] Full-face helmets are widely used as important head protection equipment because they provide comprehensive protection for the rider's face and chin. However, traditional full-face helmets generally have the defect of insufficient breathability in their design. In cold or large temperature difference environments, the user's exhaled hot and humid air cannot escape effectively due to the helmet's airtightness. When it comes into contact with the cool inner surface of the lens, it will quickly condense into fog, seriously interfering with the rider's vision and posing a significant safety hazard. To address this, we propose a new type of full-face helmet. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a full-face helmet to solve the problem that in cold or large temperature difference environments, the visor of a full-face helmet is prone to fogging, affecting the rider's vision.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a full-face helmet, including a full-face helmet body and a visor disposed at the opening position on its front side. The lower part of the front side of the full-face helmet body is provided with a ventilation structure that penetrates through the inside and outside. The ventilation structure is provided with a closure that can be selectively opened or closed to control the airflow between the inside and outside of the full-face helmet.

[0005] Furthermore, the ventilation structure includes a pair of ventilation channels penetrating the interior of the full-face helmet body. A connecting frame is provided inside the ventilation channel. The sealing component includes a sealing disc adapted to the inner diameter of the ventilation channel. A connecting rod is provided on the side of the sealing disc facing the outer side of the full-face helmet body. An insertion hole for inserting the connecting rod is opened in the middle of the connecting frame.

[0006] Furthermore, the connecting frame is located close to the outer side of the full-face helmet body, and a limiting ring is fitted on the outer wall of the connecting rod to limit the distance between the sealing disc and the connecting frame.

[0007] Furthermore, the front side of the ventilation channel has an inclined structure, so that when the closure is inserted into the ventilation structure from the outside of the full-face helmet body, the inside of the ventilation structure is not completely closed.

[0008] Furthermore, a lifting plate that can be raised and lowered is slidably connected to the lower edge of the front opening of the full-face helmet body, so as to cover the user's mouth and nose when the lifting plate is pulled up.

[0009] This utility model embodiment provides a full-face helmet, which has the following beneficial effects:

[0010] 1. Active ventilation is achieved through a quick-release and detachable breathable closure. Combined with the lifting plate structure at the mouth and nose, it effectively guides exhaled hot air away from the lens. Through these dual measures, the risk of lens fogging is significantly reduced, ensuring clear visibility while riding and improving driving safety.

[0011] 2. The closure uses a combination of a limiting ring and an inclined channel, which can maintain air circulation inside the helmet and prevent cold wind from blowing directly on the face in winter. It cleverly balances ventilation needs and heat preservation effects, and significantly improves the comfort of the body. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] See attached document Figure 1-4 A full-face helmet includes a full-face helmet body 1 and a visor 2 disposed at an opening on its front side. The visor 2 is slidably connected to the full-face helmet body 1, and the opening of the full-face helmet body 1 can be opened or closed by moving the visor 2.

[0019] The lower front of the full-face helmet body 1 has a ventilation structure that extends through the interior and exterior. This ventilation structure includes a pair of ventilation channels 31 penetrating the interior of the full-face helmet body 1. A connecting frame 32 is located within each ventilation channel 31. The ventilation structure also includes a closure that can be selectively opened or closed. The closure includes a sealing disc 41 that matches the inner diameter of the ventilation channel 31. The sealing disc 41 is made of rubber or silicone to ensure a tight seal. A connecting rod 42 is located on the side of the sealing disc 41 facing the outside of the full-face helmet body 1. A central opening in the connecting frame 32 allows the connecting rod 42 to be inserted. The length of the connecting rod 42 is greater than the width of the connecting frame 32. When the connecting rod 42 is inserted into the socket of the connecting frame 32, the end of the connecting rod 42 will protrude from the connecting frame 32. When the user needs ventilation, the user first squeezes the end of the connecting rod 42 with his / her finger, so that the sealing plate 41 is pushed out from the ventilation channel 31. Then, pulling the sealing plate 41 can separate the sealing part from the ventilation structure, so that the ventilation channel 31 can be opened quickly and conveniently, realizing ventilation and avoiding the problem of fogging inside the lens 2 affecting the user's vision when riding in winter.

[0020] It should be noted that the connecting rod 42 has friction with the socket, and the connecting rod 42 will not move arbitrarily after being inserted into the socket.

[0021] Furthermore, the connecting frame 32 is located close to the outer side of the full-face helmet body 1, and the outer wall of the connecting rod 42 is fitted with a limiting ring 43 to limit the distance between the sealing plate 41 and the connecting frame 32. When the sealing part is removed from the inside of the full-face helmet body 1, it is inserted into the ventilation structure from the outside of the full-face helmet body 1. At this time, the connecting rod 42 is inserted into the insertion hole of the connecting frame 32. Under the action of the limiting ring 43, there is a gap between the sealing plate 41 and the connecting frame 32. At this time, the sealing plate 41 will not completely seal the ventilation channel 31. This facilitates the fixation after the sealing part is removed, and also prevents air from being blown directly into the interior of the full-face helmet body 1 through the ventilation channel 31 during winter riding, effectively ensuring the temperature inside the full-face helmet body 1 and improving comfort during ventilation.

[0022] Furthermore, the front of the ventilation channel 31 has an inclined structure. When the closure is inserted into the ventilation structure from the outside of the full-face helmet body 1, due to the presence of the inclined structure and the limiting ring 43, the sealing disc 41 cannot completely cover the entire cross section of the ventilation channel 31, so that the inside of the ventilation structure is not completely closed. This still retains a part of the airflow channel to achieve micro-ventilation, ensuring the circulation of air inside and outside while ensuring that cold air from the outside will not blow directly on the user's face, thus improving comfort.

[0023] A lift plate 5 that can be raised and lowered is slidably connected to the lower edge of the opening on the front side of the full-face helmet body 1. The lift plate 5 is connected to the full-face helmet body 1 through a slide rail or slot structure. When the user manually pulls the lift plate 5 up, the lift plate 5 can cover the user's mouth and nose area, forming an additional barrier. When the user exhales, the exhaled hot air will not directly contact the lens 2. Combined with the open ventilation structure, it can prevent the surface of the lens 2 from fogging up, which greatly improves the user's driving safety.

[0024] It should be noted that there is friction between the lifting plate 5 and the full-face helmet body 1. After the lifting plate 5 is pulled up, it will not automatically fall back down under the action of friction.

[0025] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
