Description

Motorcycle helmet adaptive to movement speed

[0001] The present invention relates to a helmet worn for the safety of a motorcycle rider, and more specifically, to a motorcycle helmet designed to solve the problem of discomfort in wearing the helmet and reduced motorcycle driving efficiency when a motorcycle rider wears a helmet on their head to prevent head injury from an accident while riding the motorcycle, but when delivering or riding the motorcycle while wearing the helmet in high-temperature areas or when the external temperature itself is high, such as in summer, the temperature inside the helmet rises due to the high external temperature and the restricted airflow inside and outside the helmet also causes the temperature inside the helmet to rise.

[0002] In general, helmets are worn to prevent head injuries from accidents during work, such as at firefighting or construction sites. Additionally, they must be worn by law for the safety of the driver when operating two-wheeled vehicles, such as motorcycles or bicycles.

[0003] Conventional helmets typically consist of an outer shell formed in a hemispherical shape to protect the head, a liner installed on the inner side of the outer shell to cushion impact and contact the wearer's head, and a fixing part installed on the outer shell to secure the helmet to the wearer's head.

[0004] These conventional helmets have an outer shell made of a rigid material to protect the wearer's head in the event of an accident and are firmly secured to the head by fastening parts. As a result, not only is the airflow inside and outside the helmet restricted, but in the case of firefighting helmets used at fire scenes, the internal temperature rises rapidly due to heat, causing discomfort to the wearer and reducing work efficiency.

[0005] Furthermore, with the recent development of delivery culture, deliveries using two-wheeled vehicles such as motorcycles are rapidly increasing. However, wearing a helmet is legally mandatory when operating these vehicles, and when driving in the summer, the internal temperature rises not only due to the rider's vigorous movements but also because it heats up from the sunlight. Consequently, there is a problem of reduced work efficiency as there is no effective method to lower the internal temperature.

[0006] In a situation where a helmet must be worn, Korean Published Patent No. 10-2017-0110375 discloses a “helmet equipped with a thermoelectric element” as a method to lower the temperature inside the helmet. The “helmet equipped with a thermoelectric element” discloses a helmet in which a thermoelectric element (210) is placed between an outer shell (100) and a liner (220) and connected to a heat dissipation unit (230) to supply electrical energy to the thermoelectric element (210) to release heat from inside the helmet to the outside. However, since the thermoelectric element (210) must be placed inside the helmet and electrical energy must be supplied during the heat absorption process of the thermoelectric element (210), the cost of manufacturing the helmet increases and the structure of the helmet is complex, making it burdensome for a driver operating a two-wheeled vehicle to use. Furthermore, since the weight of the helmet increases, there is a problem that the burden on the musculoskeletal system of the neck area increases when worn for a long time.

[0007] The present invention aims to solve the above-mentioned problems by providing an inlet at the front of the helmet through which external air can be introduced so that external air can be naturally introduced, and the external air introduced through the inlet passes through the inside of the helmet and is discharged to the neck area of ​​the wearer, thereby helping to cool not only the inside of the helmet but also the wearer; the inside of the helmet can be efficiently cooled through a detachable cooling agent in the flow path leading from the inlet to the discharge; a blower module is installed at the rear of the helmet to cool the inside of the helmet even when it is stopped; and the operation of the blower module is controlled through the amount of power delivered to the blower module, thereby providing a motorcycle helmet that adapts to the speed of movement.

[0008] To achieve the above objectives, the motorcycle helmet with adaptive movement speed according to the present invention comprises a helmet body that protects the wearer's head, wherein the helmet comprises: an inlet installed at the front of the helmet body through which external air flows into the helmet body; an outlet through which air flowing into the helmet body through the inlet passes through the helmet body and is discharged to the outside of the helmet body; a blower module installed at the rear of the helmet body to form an airflow inside the helmet body; a power module that supplies power to enable the blower module to form an airflow; and a control module that controls the power module according to the amount of air flowing into the inlet to control the rotational speed of the blower module.

[0009] In addition, the exhaust port is characterized by being formed at the lower part of the helmet body so that air introduced through the inlet port is discharged to the wearer's neck area.

[0010] In addition, the power module includes a battery that can be detachably attached to / detachably attached to the rear part of the helmet body.

[0011] In addition, the power module includes a power input section that extends from the helmet body by a preset length, and the power input section is electrically connected to a motorcycle ridden by the wearer to receive power from the motorcycle.

[0012] In addition, the control module is characterized by calculating the degree of air flow that flows into the inlet and is discharged to the outlet through the magnitude of the current supplied to the blower module.

[0013] In addition, it further includes a cooling section installed in the path where air flowing in through an inlet installed in the helmet body moves, and a cooling agent installed to lower the temperature of the air flowing in from the inlet.

[0014] In addition, the above cooling unit is characterized by being installed in such a way that a cooling agent is installed / separated within the cooling unit in a detachable manner.

[0015] In addition, the blower module includes a recessed blower fan embedded inside the helmet body, and the recessed blower fan is characterized by discharging air entering through the inlet to the lower part of the helmet body.

[0016] In addition, the lower part of the helmet body is characterized by having a dispersion module with two or more holes formed therein to disperse the air discharged from the embedded blower fan.

[0017] In addition, the density of holes formed in the dispersion module is characterized by increasing as it moves further away from the embedded blower fan.

[0018] The present invention, configured as described above, provides an inlet at the front of the helmet through which external air can be introduced, allowing outside air to naturally flow in without a separate device.

[0019] In addition, outside air entering through the inlet passes through the inside of the helmet and is discharged through the wearer's neck area, thereby cooling not only the inside of the helmet but also the wearer.

[0020] In addition, the interior of the helmet can be efficiently cooled by lowering the temperature of the air entering from the inlet through a detachable coolant in the flow path leading from the inlet to the outlet.

[0021] In addition, a blower module is installed at the rear of the helmet to cool the interior even when the helmet is stationary, and the operation of the blower module can be controlled through the amount of power delivered to the blower module, thereby allowing for the efficient use of limited power.

[0029] To achieve the above objectives, the motorcycle helmet with adaptive movement speed according to the present invention comprises a helmet body that protects the wearer's head, wherein the helmet comprises: an inlet installed at the front of the helmet body through which external air flows into the helmet body; an outlet through which air flowing into the helmet body through the inlet passes through the helmet body and is discharged to the outside of the helmet body; a blower module installed at the rear of the helmet body to form an airflow inside the helmet body; a power module that supplies power to enable the blower module to form an airflow; and a control module that controls the power module according to the amount of air flowing into the inlet to control the rotational speed of the blower module.

[0030] A motorcycle helmet with a speed-adaptive design according to the present invention will be described in detail below with reference to the drawings.

[0032] Helmets are worn to prevent head injuries from accidents during work at sites such as firefighting or construction, but they are also legally mandatory for the safety of drivers operating two-wheeled vehicles, such as motorcycles and bicycles. However, in high temperatures or hot weather, the internal temperature of the helmet rises, causing discomfort to the wearer or reducing work efficiency by requiring work to be suspended to lower the temperature. Conventional helmets designed to address these issues were heavy and had complex designs for cooling the interior.

[0033] To solve these problems, the motorcycle helmet with adaptive movement speed according to the present invention comprises: an inlet section (100) installed in a predetermined area at the front of a helmet body (10) having a certain durability to protect the wearer's head in the event of an accident, and one or more inlet sections (100) installed to allow external air to flow into the helmet body (10); an outlet section (200) provided to allow the air flowing into the inlet section (100) to pass through the inside of the helmet, lower the temperature inside the helmet, and be discharged to the outside of the helmet body (10); a blower module (300) installed at the rear of the helmet body (10) to form an airflow to discharge the air inside the helmet body (10) to the outside; a power module (400) that supplies power necessary for the blower module (300) to operate to discharge air to the outside; and a control module (500) that calculates the amount of air flowing in from the inlet section (100) and controls the rotational speed of the blower module (300) based on this. Additionally, it further includes a cooling unit (600) positioned in the path of air that flows into the inlet (100) and is discharged through the outlet (200) or the blower module (300), which lowers the temperature of the air flowing into the inlet (100).

[0034] The inlet section (100) of the present invention is provided in the front part of the helmet body (10) and is configured to allow air from the helmet body (10) to flow into the interior, thereby enabling air circulation inside the helmet. The inlet section (100) is provided on the front of the helmet body (10), so that air naturally flows into the interior of the helmet body (10) without any separate configuration due to the airflow formed when the wearer travels on a two-wheeled vehicle such as a motorcycle. The helmet must be worn when operating or riding a two-wheeled vehicle, and is provided in an open shape so that the wearer's gaze is directed forward; it is desirable to provide the inlet section (100) in several places near the open area. By providing the inlet section (100) in several places on the front part of the helmet body (10) in this way, air can be introduced in various directions, thereby allowing the air to flow in efficiently. Additionally, although not shown, an opening / closing part (not shown) may be installed in the inlet (100) to allow the inlet (100) to be opened and closed, thereby preventing rainwater from entering through the inlet (100) when driving in rainy weather, and the opening / closing part may be closed to block the entry of air when there is no need for air to enter the helmet due to low external temperatures, such as in winter. Furthermore, the amount of air entering through the inlet (100) may be controlled at the source by keeping some parts open and some parts closed.

[0035] The exhaust section (200) of the present invention is configured such that air introduced through the inlet section (100) passes through the interior of the helmet body (10) and is then discharged to the outside. The speed-adaptive motorcycle helmet of the present invention lowers the internal temperature as air introduced through the inlet section (100) passes through the interior of the helmet body (10) and is discharged through the exhaust section (200). The exhaust section (200) is positioned considering the shape of the interior of the helmet, and it is preferable that it be positioned on the opposite side of the inlet section (100). Accordingly, it is preferable that the opposite side of the inlet section (100), which is positioned on the front of the helmet body (10), be positioned on the rear of the helmet body (10), and it may also be positioned on the side for air circulation on the side as well as the top of the helmet. In particular, as shown in FIG. 2, when the exhaust part (200) is positioned at the bottom of the helmet body (10), the air introduced into the inlet part (100) is discharged to the bottom of the helmet body (10), and since the bottom of the helmet is the wearer's neck and shoulders, the discharged air has the effect of cooling the wearer's neck and shoulders.

[0036] The blower module (300) of the present invention is configured to form an airflow to discharge air that has been introduced into the inlet (100) to the outside of the helmet body (10). When the wearer wearing the helmet is not moving or is moving at a low speed, the circulation of air that is introduced through the inlet (100) and discharged through the outlet (200) does not occur naturally, so the blower module (300) is driven to artificially form an airflow. The blower module (300) consists of a blower fan (310) for forming an airflow and a driving part such as a motor for driving the blower fan (310). The blower module (300) of the present invention is controlled through a control module (500). By using a sensor that detects the magnitude of power, such as the amount of current supplied to the blower module (300), and a sensor that detects the rotational speed of the blower fan (310), it is determined whether air is being drawn into the inlet (100). If it is determined that air circulation occurs without the operation of the blower module (300), the operation of the blower module (300) is stopped, thereby efficiently reducing power consumption. For example, when power of 'a' is supplied, if the rotational speed is 'b', air circulation occurs; however, if the rotational speed is 'c', which is greater than 'b', it is determined that the rotation of the blower fan (310) increases due to the airflow, and thus the amount of power supplied to the blower module (300) is reduced or stopped. Conversely, based on the case where the rotational speed of the blower fan (310) is d, the power supplied is detected, and if the power is high, it is determined that there is no airflow, and if it is low, it is determined that there is airflow, so the power supplied to the blower module (300) can be reduced or stopped. The blower module (300) of the present invention can receive power from a motorcycle battery provided externally through the power input part (420), but it can also receive power through a battery (410) installed in the helmet body (10). When power is received through a battery (410) installed in the helmet body (10), it is necessary to efficiently control the operation of the blower module (300) because the limited power must be used efficiently.The blower module (300) can be efficiently controlled through the rotational speed of the blower fan (310) and the strength of the power supplied to the blower module (300), which allows the battery (410) to be used for a longer period of time on a single charge. In addition, as shown in FIG. 5, if the blower fan (310) is provided at the bottom of the helmet body (10) as a discharge part (200), the air discharged to the outside is blown toward the wearer's shoulder or neck area, which helps not only with air circulation inside the helmet body (10) but also with cooling the wearer down.

[0037] Additionally, FIGS. 6 and 7 illustrate another embodiment of the motorcycle helmet of the present invention, wherein a recessed blower fan (320) is installed at a preset location inside the helmet body (10), and a dispersion module (330) is installed at the bottom of the helmet body (10) to evenly disperse the airflow formed by the recessed blower fan (320) and discharge it to the shoulder and neck area of ​​the wearer. The speed-adaptive motorcycle helmet of the present invention is configured such that the blower fan (310) allows air to flow into the inlet (100), cools the head of the helmet wearer, and then discharges it to the outlet (200). In the helmet of the present invention in which the recessed blower fan (320) is installed, about 2 to 3 Sirocco-type recessed blower fans (320) are installed inside the helmet body (10), so that the air flowing into the inlet (100) is discharged to the bottom of the helmet body (10). By controlling the airflow in this way, the wearer's head can be cooled, and at the same time, air can be discharged to the wearer's neck or shoulder area to cool the neck or shoulder area secondarily. This has the effect of cooling not only the wearer's head but also their neck and shoulders even when the wearer is stationary. When air is discharged from the embedded fan (320) installed in the helmet body (10) in this way, only the part where the embedded fan (320) is installed is cooled. However, in order to cool the wearer's neck and shoulders as a whole, multiple embedded fans (320) must be installed, which increases power consumption and reduces the time that can be used with a single battery (410) charge. To solve this problem, only 2 to 3 embedded fans (320) are installed in the helmet body (10), and a dispersion module (330) is installed in the lower part of the helmet body (10) to disperse the air discharged from the embedded fans (320), thereby allowing air to be discharged from the entire lower part of the helmet body (10), including the wearer's neck and shoulders. A passage (340) for delivering air is installed between the embedded fans (320) and the dispersion module (330).This has the effect of increasing cooling efficiency while minimizing power consumption. The configuration is such that holes are formed to disperse and discharge air, with the dispersion module (330) mounted on the lower part of the helmet body (10). To disperse air more efficiently, it is desirable to vary the density of the holes formed in the dispersion module (330). That is, fewer holes are formed at the lower part of the embedded blower fan (320), and more holes are formed as they move further away from the embedded blower fan (320), so that air can be discharged uniformly throughout. If the density of the holes is the same, most of the air will be discharged to the area close to the embedded blower fan (320), and air may not be discharged through the remaining holes; therefore, the density of the holes is increased as they move further away from the embedded blower fan (320) to ensure uniform air discharge.

[0038] As previously described, the power module (400) of the present invention is configured to supply power to the blower module (300). Power supply may be provided from the outside through the power input unit (420) as shown in FIG. 1, or it may be supplied from the battery (410) by placing the battery (410) in the helmet body (10) as shown in FIG. 4. It is preferable to use a universal method such as USB for the power input unit (420), and a configuration must be provided to connect the power input unit (420) to the two-wheeled vehicle ridden by the wearer. When using the power input unit (420), power is supplied from the outside, so the need for efficient use of power consumption is small; however, when using the battery (410) in the helmet body (10), efficient use of power consumption is very important, taking into account the capacity and weight of the battery (410). For convenience of use, the battery (410) is configured to be detachable and a power input (420) is also provided so that when the power input (420) is used, the battery (410) can be detached to reduce the weight of the helmet or to be used for charging the battery (410).

[0039] As described above, the control module (500) of the present invention controls the power supplied to the blower module (300) to be reduced or stopped according to the movement speed for efficient operation of the blower module (300).

[0040] The cooling unit (600) of the present invention is configured to lower the temperature inside the helmet body (10) by being placed in the path where air moves from the inlet (100) to the outlet (200). The cooling unit (600) may be placed on both sides of the helmet body (10) as shown in FIG. 4, or it may be efficiently placed according to the shape of the helmet. The cooling unit (600) is provided as a detachable unit so that if the cooling performance of the cooling unit (600) decreases, it can be immediately replaced with another cooling unit (600) to efficiently maintain the cooling performance. It is preferable that the cooling unit (600) be composed of a material that has a melting point between approximately 5°C and 28°C and has fluidity after becoming a liquid. For example, the cooling unit (600) uses a phase change material (PCM), which is a material that absorbs heat when changing from a solid to a liquid and releases stored heat when changing from a liquid to a solid. Since the cooling sheet for a helmet according to the present invention is used at room temperature, it is preferable to use a phase change material that melts at room temperature.

[0041] For example, it is preferable to use one of CH3-(CH2)12-CH3 (tetradecane) with a melting point of 5.5°C, CH3-(CH2)14-CH3 (hexadecane) with a melting point of 18°C, CH3-(CH2)15-CH3 (heptadecane) with a melting point of 22°C, or CH3-(CH2)16-CH3 (octanedecane) with a melting point of 28°C. Although a lower melting point has the advantage of being able to be used for a longer period because it stores a larger amount of latent heat, it takes a long time to return to a solid state, so it is advisable to select one according to the wearing environment.
