Description

Helmet {Helmet}

The present invention relates to helmets. In one embodiment, the helmet of the present invention can prevent accidents by preventing fogging or frost forming on the surface of the window.

A helmet is a device that protects the user's head. Helmets act on the head to protect it from external impacts. Some helmets have a window made of glass or transparent polymer, such as transparent polycarbonate, attached to the front to prevent the user's view from being blocked by wind or dust. These windows provide convenience and stability to the user, but when there is a temperature difference between the inside and outside of the helmet, fog or frost forms on the surface of the window, blocking the user's view.

Various studies are being attempted to solve these problems. Among prior art documents, Korean Utility Model Publication No. 20-1996-0004881 discloses a helmet that prevents fogging and frost by forming a window with an exposed lens and a surface lens and forming an air gap between them. In addition, Korean Patent Registration No. 10-2377206 discloses a protective film for the face shield of a helmet that can improve visibility by attaching several layers of protective film and removing them one by one when necessary.

However, with this method, there is a problem in that it is difficult to immediately remove fogging or frost that occurs due to temperature changes during operation.

1 shows a helmet according to an embodiment of the present invention. Referring to Figure 1, a helmet 100 according to an embodiment of the present invention includes a protective member 110 that protects the head; A window member 120 disposed in front of the protective member 110 and including a window 121 that transmits visible light and a heating wire 122 that controls the surface temperature of the window 121; and a temperature sensor 130 that measures the temperature inside the protective member 110 or on the surface of the window 121.

Figure 3 shows a helmet according to another embodiment of the present invention. Referring to FIG. 3, it may further include an air circulation member 140 that circulates the air inside the protective member 110.

In the present invention, the function, material, and other components of the helmet 100 may be the same as those of a general helmet.

The protective member 110 performs the function of protecting the head. The protective member 110 may be shaped to cover at least part of the head, and can be used by the user by putting the protective member 110 on the head. The protective member 110 has a shape that provides a space to accommodate the user's head, and may further include a binding member to prevent the user's head from coming off. The binding member is a component commonly used in the helmet 100 and may include components such as a belt, strap, button, and buckle. The shape or material of the protective member 110 is not particularly limited.

The window member 120 performs the function of protecting the user's face, especially the eyes. The window member 120 has certain transparency to visible light and can be arranged to cover the user's face, especially the eyes. The protective member 110 may be formed so that the portion where the user's face is located is open, and the window member 120 may be disposed in this portion. Both edges of the window member 120 are attached to the protection member 110 through a hinge, so that the window member 120 can be mounted to move up and down. Through this, the user can have the window member 120 cover the user's face only when necessary.

Referring to Figure 2, the window member 120 includes a window 121 and a heating wire 122.

The window 121 may have a certain level of transparency to ensure the user's field of view while performing the function of protecting the user's face, especially the eyes. The window 121 may be made of glass or a transparent polymer material (for example, transparent polycarbonate, etc.), and may be formed by stacking several layers as needed. In one embodiment, the window 121 may have the function of blocking ultraviolet rays and may have the function of controlling the amount of visible light transmitted. This can protect the user's eyes. At this time, the window 121 may include a functional film that blocks ultraviolet rays or visible rays. The window 121 may have an appropriate size, shape, and thickness to protect the user's face and/or eyes, but is not particularly limited.

The heating wire 122 functions to control the temperature of the surface of the window 121. The heating wire 122 may be disposed on the surface of the window 121, particularly on the inner space where the user's face and head are accommodated. In one embodiment, the heating wire 122 may be disposed inside the window 121. In this case, the window 121 may be formed by stacking at least two layers, and the heating wire 122 may be disposed between the two layers. The heating wire 122 may be formed only on a portion of the window 121 so as not to block the user's view. At this time, the heating wires 122 may be formed in horizontal or vertical rows, or may be formed in a certain pattern so as not to interfere with the user's field of view. In another embodiment, the heating ray 122 may be formed of a material that is transparent to visible light. Through this, it is possible to generate heat without blocking the user's view. The heating wire 122 may be made of a material that generates resistance heat due to the movement of electric current. As an example, the heating wire 122 may be made of metal or alloy, and may be formed of a conductive polymer or a material in which a conductive material (such as a metal) is dispersed in the polymer. The method of manufacturing the heating wire 122 may be a general method of forming a conductive material on a glass or polymer layer and is not particularly limited. In one embodiment, this may be done by printing or coating the surface of the window 121 using conductive ink. The number, thickness, resistance, etc. of the heating wires 122 are not particularly limited.

The temperature sensor 130 is a device that measures the temperature inside the protective member 110 or on the surface of the window 121. Through this, it is possible to determine whether the heating wire 122 and/or the air circulation member 140 is operating. The temperature sensor 130 may be disposed inside the protective member 110 and/or on the surface of the window 121. Referring to FIG. 2, the temperature sensor 130 is disposed on the inner surface of the window 121. The temperature sensor 130 is not particularly limited as long as it is used for temperature measurement.

The air circulation member 140 functions to circulate the air inside the protective member 110. Through this, it is possible to prevent steam or frost from being generated on the inner surface of the window 121, and to effectively remove steam or frost that has already been created. There is a problem in that it is difficult to effectively prevent steam and/or frost generated when the temperature inside and outside of the protective member 110 changes rapidly with the heating wire 122 alone, and it is difficult to immediately change the temperature of the surface of the window 121. Because it takes time to control, there is a problem that the user's view is temporarily obscured. In another embodiment of the present invention, fog and/or frost generated on the inner surface of the window 121 can be effectively removed by circulating internal air through the air circulation member 140.

Figure 4 is a view of the air circulation member 140 from the circulation unit 142. The air circulation member 140 may include a circulation unit 142 that circulates the air inside the protection member 110. The air circulation member 140 may be disposed inside the protective member 110, and may preferably be located at a portion of the protective member 110 that contacts the window member 120. Through this, the air released from the circulation unit 142 can circulate inside the protective member 110 and reach the surface of the window 121 to more effectively remove fog and/or frost. In one embodiment, the circulation unit 142 includes a motor and a fan rotated by the motor, and may circulate air by operating the fan (see FIG. 4). In another embodiment, the circulation unit 142 may be a pipe or nozzle connected to the inlet 141, which will be described later. At this time, the circulation unit 142 may perform the function of moving air flowing in from the outside of the helmet 100 to the inside.

The air circulation member 140 may include a heating unit 143 that controls the temperature of the air circulating in the circulation unit 142. The heating unit 143 may set the temperature of the air circulating in the circulation unit 142 to 20 to 30°C, preferably 25°C. Through this, steam and/or frost generated on the surface of the window 121 can be removed more quickly. The heating unit 143 is not particularly limited as long as it heats air. In one embodiment, the heating unit 143 may include a wire, a coil, etc. that generate resistance heat by the flow of current. The heating unit 143 may be disposed at the front or rear end of the fan, pipe, or nozzle of the circulation unit 142. Referring to FIG. 4, it can be seen that the heating unit 143 is disposed between the inlet unit 141 and the circulation unit 142.

The air circulation member 140 may further include an inlet that introduces air outside the protective member 110. The air circulated by the circulation unit 142 may be air outside the helmet 100. Through this, air containing a constant amount of oxygen can be provided to the user, and the content of carbon dioxide and moisture can be prevented from increasing due to the user's exhaled breath. The inlet may be disposed on one side of the protective member 110, or may be a pipe or hole disposed to penetrate the protective member 110. Preferably, the inlet portion may be disposed to penetrate a portion of the protective member 110 where the upper portion of the window member 120 is disposed.

When the inlet part is formed, the circulation part 142 may include components such as pipes and nozzles that guide the air introduced from the inlet part into the inside of the protective member 110, and may contain components such as pipes and nozzles that guide the air introduced from the inlet part It may further include a valve that blocks movement. Additionally, the heating unit 143 may be disposed between the inlet unit and the circulation unit 142.

In order to control the surface temperature of the window 121 through the heating wire 122 and/or the air circulation member 140, the helmet 100 receives temperature information from the temperature sensor 130, and the temperature It may further include a control member that controls power supply to the heating wire 122 and the air circulation member 140 based on the information. The control member is a controller that controls the operation of components such as the temperature sensor 130, the air circulation member 140, and the heating wire 122 and receives information, and the air circulation member 140 or the heating wire 122. It may include a power device that supplies power.

The controller may include at least one processor chip, and may control the operation of each component by running a software program embedded in the processor chip.

The power device is not particularly limited as long as it can supply power to the heating wire 122, and for example, it may be a primary or secondary battery.

The control member may receive the temperature measured by the temperature sensor 130 and, if it is lower than the reference temperature, apply current to the heating wire 122 to increase the temperature of the surface of the window 121. At this time, the preferred surface temperature of the window 121 may be 10 to 20°C.

Additionally, the control member may receive the temperature measured by the temperature sensor 130 and operate the air circulation member 140 when the temperature is lower than the reference temperature. Additionally, the air can be heated by operating the heating unit 143 of the air circulation member 140. At this time, the preferred air temperature may be 20 to 30°C.

The present invention is not limited by the above-described embodiments and attached drawings, but is intended to be limited by the attached claims. Accordingly, various forms of substitution, modification, and change may be made by those skilled in the art without departing from the technical spirit of the present invention as set forth in the claims, and this also falls within the scope of the present invention. something to do.
