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

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 configured based on the structure of a basic motorcycle helmet composed of an outer casing (10), a shock absorbing member (20) positioned inside the casing (10), and a chin strap. At this time, it is configured to circulate the external air through the casing 10 and the buffer member 20 to the head of the inner wearer and then discharge it to the outside.

In the case of a chin strap provided together, as a means for fixing the chin around the chin after wearing the casing 10 to which the cushion member 20 is coupled to prevent the helmet from peeling off in a worn state, this is a known configuration. Therefore, in the present invention, a detailed description is omitted.

In the present invention, the 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 front part is partially opened so that the outside air in front flows into the casing 10. Basically, when driving a motorcycle, it is installed on the front of the casing 10 to reflect the position and shape that minimizes resistance while being natural by reflecting the airflow movement outside the casing 10.

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. Can be Accordingly, it is necessary to have a size that allows air to flow in smoothly while preventing the durability of the casing 10 from deteriorating, and for this purpose, rather than forming one intake part 11, two or more relatively small as shown in the accompanying drawings It is preferable to form the

intake parts

11 and 11 in size, and to form a pair in a form in which the casing 10 is deflected to the front left and right, respectively.

In this case, excessively low air may be introduced, such as a situation in which rainwater flows through the intake unit 11 during rainy weather or in winter when the temperature is low. In the present invention, in order to prevent this, the intake unit 11 is provided with an opening and closing plate 12 that can be opened and closed in a slide manner.

The exhaust part 13 is configured to discharge the air inside, that is, the inside air to the outside in a form in which the outer rear surface of the casing 10 is partially opened. Considering the aerodynamic shape and as described above, in order to prevent rainwater or the like from entering in the rain, an exhaust cover 14 having a partially covered 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, forced suction, circulation, and exhaust of air using the blower fan 30 are performed in parallel, as described below. Accordingly, a storage unit 15 for accommodating a power source, that is, a battery 41 and a control circuit, is formed inside the rear side of the casing 10 for controlling the blowing fan 30, and the storage unit 15 A cover 16 for covering and protecting is provided.

The cushioning member 20 is configured to be installed inside the casing 10 to absorb external shocks and protect the wearer's head. The material can be appropriately selected from known materials including Styrofoam, and the present invention presents an optimal form for circulating and discharging the inside of the external air cushion member 20.

To this end, the buffer member 20 is in the form of communicating 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) for penetrating the air of the outside and leading to the exhaust portion (13).

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 disposed 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). Specifically, when the helmet is worn, the head portion is in close contact with the cushioning member 20, and thus, such a ventilation path is formed in a groove-like shape on the inner surface in a range that does not degrade the strength of the cushioning member 20 and forms an air passage.

The first ventilation passage 21 is basically a passage through the buffer member 20 and formed to contact the intake part 11 so that the introduced air can move along the inner wall. In addition, it is formed to cross the front-rear direction of the shock absorbing member 20 so that the flow of space air between the crown portion and the shock absorbing member 20 worn by the user.

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. It includes a second passage 212 for guiding a part of, it 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 a protrusion.

The second ventilation path 22 is configured to pass through the buffer member 20 at the rear side of the crown, and an air blowing fan 30 is installed to suck air inside the buffer member 20 to exhaust the exhaust portion 13 ) To the outside.

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 that the air inside the member 20 is configured to discharge directly to the outside.

In addition, a plurality of blowing fans (31, 32, 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 forced circulation of air. In addition, natural air inflow and exhaust may be used by selectively stopping the blowing fan 30, such as smooth air inflow due to high-speed operation of a motorcycle or winter when the external 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 composed 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 mentioned above, the blower fan 30 is operated at all times, such that forced suction and circulation of external air can be continuously performed 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 blowing fan 50 may be provided with a total of three, a central blowing fan 32 and 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.
