Hereinafter, the configuration of the motorcycle helmet having the ventilation control function of the present invention will be described in detail.

Figure 1 is a front perspective view showing the appearance according to an embodiment of the present invention, Figure 2 is a rear perspective view showing the appearance according to an embodiment of the present invention, Figure 3 is an exploded perspective view according to an embodiment of the present invention, the present invention is external The casing 10, the casing 10 is located on the inside of the basic structure of the motorcycle helmet consisting of a shock absorbing member 20 and a chin strap to wrap the wearer's head, and the outside air is the casing 10 and It is configured to pass through the buffer member 20 and circulate to the head portion of the inner wearer, and then discharged again.

In the case of a chin strap provided together, the present invention is described as it is a known configuration as a means for fixing the casing 10 to which the shock absorbing member 20 is coupled around the chin to prevent the helmet from being randomly removed while worn. Is omitted.

In the present invention, the outer casing 10 is provided with an intake portion 11 and an exhaust portion 13.

The intake part 11 is configured such that the outside of the outside is partially opened so that the outside air in the front flows into the casing 10 inside. Basically, when driving a motorcycle, the airflow movement outside the casing 10 is reflected to minimize natural and resistance. It is installed on the front of the casing 10 to reflect the location and shape.

At this time, the larger the size of the intake unit 11, the greater the amount of air inflow can be effective internal ventilation, but this is a factor that can degrade the durability of the casing 10 and the basic function of the helmet that protects the wearer's head during an accident. As it becomes, it is necessary to have a size that allows air to flow smoothly while preventing a decrease in durability, and for this purpose, rather than forming one intake part 11, intake in two or more relatively small sizes as shown in the accompanying drawings Forming the portions 11 and 11, it is preferable that the casing 10 is provided in a pair in the form of being biased to the left and right of the front.

At this time, for the purpose of preventing excessively low air, such as in the winter or when the rainwater flows through the intake unit 11 during rainy weather, the intake unit 11 can be opened and closed in a slide manner. The opening and closing plate 12 is provided.

The exhaust portion 13 is a configuration for discharging the inside air, that is, the inside air in the form that the outer rear surface of the casing 10 is partially opened, taking into account the aerodynamic shape and rainwater in the rain as mentioned above In order to prevent this from entering, an exhaust cover 14 having a form partially covering the upper side is provided. That is, when the motorcycle is moving in the rain, unlike the intake portion 11 in the front, the exhaust portion 13 in the rear side has relatively little inflow of rainwater. By stopping at this, the exhaust cover 14 is formed in consideration of a position where rainwater does not flow in while the driver raises his head.

In addition, in the present invention, in addition to the inflow of naturally occurring air during operation, as described below, the forced power intake, circulation, and exhaust of the air using the blower fan 30 are concurrently performed, so that power is supplied for controlling the blower fan 30, that is, A storage unit 15 for accommodating the battery 41 and a control circuit is formed inside the rear side of the casing 10, and a cover 16 is provided to cover and protect the storage unit 15.

The shock absorbing member 20 absorbs external shock and is installed inside the casing 10 to protect the wearer's head, and the material can be appropriately selected from known materials including Styrofoam. (20) An optimal form for discharging after circulation inward is presented.

To this end, the buffer member 20 of the present invention communicates with the first ventilation passage 21 and the second ventilation passage 21 which are formed to guide the air introduced through the intake part 11 inward. It is provided with a second ventilation path 22 that penetrates the air inside the furnace to the outside and leads to the exhaust portion 13 side.

4 is a perspective view showing the shape of a buffer member according to an embodiment of the present invention, FIG. 5 is a side sectional view according to an embodiment of the present invention, and FIG. 6 is a rear perspective view according to an embodiment of the present invention.

In the present invention, both ends of the intake part 11 and 11 'are respectively provided on the inner surface of the buffer member 20 so that the air introduced through the intake part 11 can effectively circulate the head part of the wearer. Ventilation paths are dug in a form that communicates with the base (13). When the helmet is substantially worn, the head portion is in close contact with the cushioning member 20, and thus, such a ventilation path is formed in the shape of a groove on the inner surface and does not degrade the strength of the cushioning member 20 and becomes an air passage.

The first ventilation passage 21 is basically formed to penetrate the shock absorbing member 20 and contact the intake part 11 to become a passage through which the introduced air can move along the inner wall, and the shock absorbing member 20 It is formed to cross the front-rear direction so that the flow of space air between the parietal part of the user and the cushioning member 20 is worn.

Specifically, the first passage 211 that crosses the inner surface of the buffer member 20 back and forth and induces a part of the air to the parietal region, and is partially communicated with the first passage 211, and is air to the left and right sides of the head. The second passage 212 for guiding a portion of the crown is configured to allow uniform air flow from the center and left and right of the crown.

To this end, the first passage 211 and the second passage 212 can be distinguished by appropriately forming the protrusion 23.

The second ventilation path 22 is configured to pass through the buffer member 20 at the rear side of the crown, and a blowing fan 30 is installed in the second ventilation path 22 so that the inside of the buffer member 20 is provided. Air is sucked and discharged to the outside through the exhaust unit 13.

At this time, as the exhaust portion 13 is installed at the rear of the casing 10, the second ventilation path 22 and the blowing fan 30 are formed to be adjacent to the exhaust portion 13 as shown in FIG. It is preferable to configure the air inside the member 20 to discharge directly to the outside, and a plurality of blowing fans 31, 32, and 33 may be installed in parallel for smooth air discharge.

That is, the blower fan 30 is provided in one or plural to be fitted to the size of the second ventilation path 22 in the center of the second ventilation path 22 to blow the air inside the buffer member 20 upward. It can be blown to the exhaust portion 13 side and is configured to be able to distinguish the air passage from the first ventilation path 21 through the partition wall-shaped protrusion 23.

The blower fan 30 is basically always operated to depressurize the inside of the shock absorbing member 20 to promote the inflow of air through the intake part 11 and allow for forced circulation of air, but high-speed operation of the motorcycle It is also possible to use a natural air inlet and outlet method by selectively stopping the blowing fan 30, such as in the winter or when the outside air temperature is low.

In addition, as described above, the storage unit 15 includes a battery 41 for supplying power required to drive the blowing fan 30, and a circuit-type control unit for driving control of the blowing fan 30 ( 40) is built.

The battery 41 may use a commercial rechargeable battery or a replaceable battery, and the control unit 40 is formed in the form of a circuit board that controls the blowing fan 30 with power supplied through the battery 41. .

At this time, the control unit 40 further includes a pressure sensor 42 installed on the intake unit 11 side to measure the pressure of the incoming air, and when the pressure of the measured air is higher than the set value, the blowing fan 30 It can be configured to stop.

That is, as described above, the blower fan 30 is operated at all times, so that it is possible to forcibly inhale and circulate outside air at all times while the motorcycle is stopped as well as during operation. In this case, air may be easily introduced through the intake unit 11 on the front side during a motorcycle operation, but air may be introduced at a pressure higher than the suction pressure through the blowing fan 30 during high-speed operation. In addition, due to the air flow characteristics outside the casing 10 due to the exhaust cover 14, a pressure drop on the exhaust 13 side may occur, so driving of the blower fan 30 may lead to unnecessary waste of power.

Accordingly, a pressure sensor 42 is installed on the intake unit 11 side to measure the pressure of the inflow air, and when the pressure of the naturally flowing air is higher than the intake due to the operation of the blowing fan 30, the ventilation Efficient power management can be achieved by stopping the fan (30).

In addition, as described above, as the plurality of the blowing fans 31, 32, and 33 are formed, the control unit of the blowing fan 30 driven according to the pressure of the air measured through the pressure sensor 42 More efficient power management can be achieved by differentially controlling the number and rotation speed. As a preferred embodiment of the present invention, as shown in the accompanying drawings, the blower fan 50 may be provided with a total of three, the central blowing fan 32 and the left and right blowing fans 31 and 33.

Correspondingly, the second passage 212 communicates with the left and right intake parts 111 and 111 ', respectively, so that air flows through the left and right blowing fans 31 and 33, respectively, and is discharged. A pair may be provided, and the first passage 211 may be configured to connect a pair of second passages 212 but allow air to flow and discharge through the central blowing fan 32.

In addition, as the skin, such as the forehead portion, and the contact portion between the buffer member 20 and sweat may be easily absorbed due to the structure, the bacterial growth or odor may be generated, so that the inner surface of the buffer member 20 directly contacts the user's skin. A deodorizing band 50 in the form of a tape can be attached. The deodorization band 50 is basically made of a fiber material capable of absorbing moisture, but may be configured to contain known components for antibacterial and deodorization.

As described, the present invention, the intake portion 11 and the exhaust portion 13 provided in the casing 10, as well as the organic introduced through a plurality of blowing fans 30 mounted on the buffer member 20 side inside By circulating and discharging in, the heat of vaporization is absorbed as the sweat evaporates, so that the temperature of the head can be lowered, and deodorization may occur due to heat, sweat or moisture discharge.

Although the present invention has been described with reference to the accompanying drawings and preferred embodiments, it is clear that those skilled in the art can make various modifications without departing from the scope of the present invention. Therefore, the scope of the invention should be construed by the claims set forth to cover these many variations.
