Description

Technical Field

[0001] The utility model relates to the technical field of helmets, in particular to a helmet with good air permeability. Background Art

[0002] A helmet is a piece of protective equipment used to protect the head. It is widely used in various situations where head protection is needed, such as motorcycle riding, bicycle riding, skateboarding, rock climbing, skydiving, racing and other sports or activities. The main function of a helmet is to reduce or avoid the risk of head being hit, scratched or otherwise injured.

[0003] In order to protect the head, the helmet will surround the head for protection, so it will be hotter when wearing a helmet.

[0004] In order to improve the comfort of the head, in the prior art, a through slot is opened on the upper end of the helmet. The wind generated during riding will enter the helmet through the through slot, thereby improving the comfort of the head. Although the through slot opened on the helmet solves the problem of ventilation, if the sun's temperature is too high, the direct sunlight will shine on the head through the through slot, causing the head to still be relatively hot and less comfortable. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a helmet with better air permeability, aiming to solve the problem in the prior art that the helmet is not comfortable to wear when exposed to direct sunlight.

[0006] The utility model is realized in this way. A helmet with good air permeability comprises a helmet shell and a helmet cavity frame. A pair of arc-shaped air passages are opened through the helmet shell from front to back. The arc-shaped air passages are symmetrically distributed on the helmet shell, and the openings of the arc-shaped air passages are opposite to each other. A hollow block is extended from the top of the helmet cavity frame toward the helmet shell, and the upper end of the hollow block is fixedly connected to the helmet shell.

[0007] Furthermore, a pair of fixing posts fixedly connected to the helmet shell are provided at both ends of the through holes of the pair of arc-shaped ventilation paths, and a blocking plate is rotatably connected to the fixing posts.

[0008] Furthermore, movable magnets are fixedly provided at both ends of the blocking plate, and a placement magnet for adsorbing the movable magnet is fixedly provided on one side of the through hole of the arc-shaped air passage.

[0009] Furthermore, the helmet shell is provided with corrugated grooves for increasing the airflow velocity, and the corrugated grooves are evenly distributed inside the helmet shell.

[0010] Furthermore, spare ventilation grooves are provided at the left and right ends of the helmet shell, and the spare ventilation grooves penetrate the helmet cavity frame.

[0011] Furthermore, the spare ventilation groove is obliquely opened on the helmet shell, and is obliquely opened downward from the inside to the outside.

[0012] Furthermore, corrugated strips are fixedly arranged in the arc-shaped ventilation passage and are evenly distributed in the arc-shaped ventilation passage.

[0013] Furthermore, through slots are provided at both ends of the helmet shell, and straps for fixing the helmet when worn are provided in the through slots, and the straps are fixedly connected to the helmet shell through the through slots.

[0014] Furthermore, the belt body of the lace is provided with ventilation holes for ventilation during riding.

[0015] Furthermore, the ventilation holes are arranged on the laces at intervals and evenly.

[0016] Compared with the prior art, the helmet provided by the utility model has better air permeability, and significantly improves the air permeability and wearing comfort during riding through the innovative arc-shaped ventilation path design and hollow block structure. The arc-shaped ventilation path not only enhances the entry of wind flow and improves the comfort of the head, but also avoids the problem of overheating of the head caused by direct sunlight. At the same time, the design of the hollow block creates space between the human head and the helmet cavity frame, further improving the wearing comfort. This design ensures that the helmet provides protection while also ensuring the rider's comfortable experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Reference Figure 1-4 As shown, a preferred embodiment of the present invention is a helmet with better air permeability, which is composed of a helmet shell 100 and a helmet cavity frame 200. The helmet shell 100 is provided with an arc-shaped air path 101 that runs through the front and back, and is symmetrically distributed on both sides of the helmet shell 100, and the openings are opposite to each other. During riding, the wind generated around the rider's head enters the upper air inlet of the helmet body 100, and the airflow will hit the helmet cavity frame 200, thereby causing the airflow path to change, and then flow out through the air outlet on the other side to form an arc-shaped airflow path 200. As riding progresses, the airflow continues to pass through the arc-shaped airflow path 200 to form an arc-shaped airflow path, thereby effectively improving the comfort of the rider's head. At the same time, the design of the arc-shaped airflow path 101 is not just for increasing air permeability. Since they are connected from front to back, even in direct sunlight, the sunlight cannot directly shine on the rider's head, which solves the problem of direct sunlight shining on the head through the through slots in traditional helmets, resulting in reduced head comfort. At the top of the helmet cavity frame 200, there is a hollow block 201 extending upward, and the upper end of this hollow block 201 is fixedly connected to the helmet shell 100. The setting of the hollow block 201 forms a certain space between the helmet body and the helmet cavity frame 200. This design not only provides better ventilation for the rider, but also greatly improves the comfort when wearing. The rider can feel the circulation of air inside the helmet, reducing the stuffiness and improving the overall riding experience.

[0025] In this embodiment, the outer side of the arc-shaped air passage 101, that is, the outer sides of the two air inlets are respectively provided with fixing columns 400 fixedly connected to the helmet shell 100, and a blocking plate 401 is rotatably connected between the two fixing columns 400. The blocking plate is arc-shaped and can just cover the two air inlets, and a rotation gap is provided between the blocking plate 401 and the helmet shell 100, so that the blocking plate 401 can rotate around the fixing columns 400, thereby enabling the blocking plate 401 to be opened or the air inlets to be blocked. Considering that when it rains and a helmet is worn, rainwater may enter the interior of the helmet through the arc-shaped air passage 101 on the helmet body, resulting in the problem of rainwater wetting the head, the blocking plate 401 is arranged to be rotatable on rainy days, thereby preventing rainwater from entering the interior of the helmet along the arc.

[0026] In this embodiment, in order to more stably adjust and fix the position of the blocking plate 401, moving magnets 500 are installed at both ends of the blocking plate 401. The moving magnets 500 are magnetic and can generate a stable adsorption force with the corresponding magnets. At the same time, a placement magnet 501 is provided on one side of the through hole of the arc-shaped air passage 101. The position of the placement magnet 501 corresponds to the moving magnet 500 on the blocking plate 401. When the blocking plate 401 is adjusted to the desired position, the moving magnet 500 will fit closely with the placement magnet 501, and the blocking plate 401 will be firmly fixed by the magnetic force between them.

[0027] In this embodiment, the corrugated grooves 600 are arranged inside the helmet shell 100 and are evenly distributed in the internal space of the helmet shell 100. When the rider wears the helmet and rides on the road, the surrounding airflow will inevitably interact with the helmet. In particular, when the airflow enters the helmet body through the sliding grooves reserved on the helmet, these corrugated grooves 600 not only provide a flow path for the airflow, but also guide the airflow to flow in an orderly manner inside the helmet through its unique corrugated shape, effectively reducing the stuffiness of the rider's head. Compared with the traditional helmet design, this helmet with corrugated grooves can provide a more comfortable wearing experience while ensuring safety.

[0028] In this embodiment, in order to meet the ventilation requirements in different riding environments, especially when riding in rainy days, spare ventilation slots 700 are opened at the left and right ends of the helmet shell 100. When the rider encounters rainy days, in order to prevent rainwater from entering the helmet through the sliding slot, the blocking plate 401 is usually adjusted to close the sliding slot at the upper end of the helmet body. However, after closing the sliding slot, the ventilation inside the helmet may be affected, giving the rider a feeling of stuffiness and discomfort. In order to solve this problem, we open spare ventilation slots 700 at the left and right ends of the helmet shell 100, which can not only ensure that rainwater will not enter the helmet through these slots when riding in rainy days, but also provide sufficient ventilation space for the helmet after closing the sliding slot.

[0029] In this embodiment, the balance between the ventilation and waterproof performance of the helmet when riding in rainy days is taken into consideration. For this reason, the spare ventilation slot 700 is tilted on the helmet shell 100, specifically tilted downward. When it rains, rainwater cannot flow into the helmet along the spare ventilation slot 700, thereby keeping the inside of the helmet dry and comfortable. The tilted downward design makes it so that when rainwater falls on the helmet, it will slide down along the surface of the helmet shell 100 instead of flowing to the spare ventilation slot 700. Even if rainwater accidentally touches the opening of the spare ventilation slot 700, its tilted downward structure will cause the rainwater to slide down quickly and cannot enter the inside of the helmet. This not only effectively prevents rainwater from penetrating, but also ensures the ventilation performance of the helmet when riding in rainy days.

[0030] In this embodiment, in order to further improve the air permeability and comfort of the helmet, a corrugated strip 800 fixedly connected to the helmet body is arranged inside the arc-shaped ventilation path 101. When the rider wears the helmet to ride, the surrounding air will naturally flow into the arc-shaped ventilation path 101. At this time, the unique structure of the corrugated strip 800 begins to play a role. Due to the concave-convex design of the corrugated strip 800, an effect similar to vortex will be produced, thereby accelerating the flow rate of air. This accelerated flow not only helps to quickly discharge the hot air inside the helmet, but also allows the outside fresh air to enter the helmet faster, forming effective air convection. The rider can feel a cooler air flow during riding, which significantly improves the air permeability and comfort of the helmet. This effect is particularly obvious in hot weather or when riding for a long time. The setting of the corrugated strip 800 not only optimizes the ventilation performance of the helmet, but also further improves the riding experience of the rider.

[0031] In this embodiment, a head strap 300 is fixedly provided at the end of the helmet shell 100. The fixation of the strap 300 facilitates fixing the helmet when the helmet is worn.

[0032] In this embodiment, ventilation holes 301 are provided on the strap 300 , and when the helmet is worn and fixed by the strap 300 , comfort can also be maintained through the ventilation holes 301 .

[0033] In this embodiment, the ventilation holes 301 are evenly arranged on the lace 300 to further improve the air permeability of the lace 300 .

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
