Description

Technology Field

[0001] An embodiment of the present invention relates to a cooling helmet that cools the wearer's head, and more specifically, it supplies air cooled by the principle of a Peltier element and a heat sink through an internal air path of the helmet at the crown of the head, thereby significantly improving the quality and reliability of the cooling helmet product, and thus satisfying the various needs of consumers and creating a positive image.

[0004] As is well known, a helmet is a hat made of materials such as iron, aluminum, styrofoam, or plastic worn to protect the head. There are helmets for construction sites, athletes, motorcycles, and astronauts.

[0005] Recently, as the quality of life of the people improves, the number of people enjoying various outdoor leisure activities and sports is increasing, and as the personal mobility sector, represented by electric wheels and electric kickboards, grows rapidly, the safety protective equipment sector is also expected to see significant growth.

[0006] The aforementioned conventional helmets merely serve to protect the head from impact, and a problem has arisen where the temperature inside the helmet rises when worn for a long time, causing discomfort to the wearer.

[0007] In order to solve this problem, a cooling helmet has been proposed in the past, but it had the problem that it was difficult to generate sufficient cold air because the cooling area of ​​the thermoelectric semiconductor was limited, and since the incoming air was discharged immediately after cooling the heating part of the thermoelectric semiconductor, it was difficult to sufficiently deliver cold air to the insertion space even though a cold air passage was formed.

[0008] In addition, the aforementioned conventional technology has the problem that it is difficult to generate sufficient cold air using only thermoelectric elements without gas flow, and consequently, it is difficult to sufficiently deliver cold air throughout the internal space of the helmet.

[0009] In addition, the above-mentioned conventional technology has a problem in that if there is no gas flow, the heat generated in the thermoelectric element is discharged efficiently, which actually promotes an increase in the internal temperature of the helmet and causes an overload of the thermoelectric element.

[0011] In order to solve the aforementioned problems, the following prior art documents were developed in the past; however, a major problem still arose in that the problems of the aforementioned prior art could not be solved all at once. Prior art literature

[0062] And it should be understood that the present invention is not limited to the specific forms mentioned in the above detailed description, but rather should be understood to include all variations, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims.

[0064] The effects of the cooling helmet of the present invention configured as described above are as follows.

[0065] First, the present invention supplies air cooled by the principle of a Peltier element and a heat sink to the crown of the head through an internal air path of the helmet.

[0066] To this end, FIG. 1 is an exploded perspective view showing the left side of the cooling module (110) applied to the present invention, and FIG. 2 is an exploded perspective view showing the right side of the cooling module (110) applied to the present invention.

[0069] And FIG. 4 is an exploded perspective view showing the right side of the cooling module (110) and inner lining (101) applied to the present invention.

[0070] In addition, FIG. 5 shows an exploded perspective view in which a cooling module (110) applied to the present invention is coupled to an inner lining (101).

[0071] Figure 6 is an exploded perspective view showing the state in which the cooling module (110) applied to the present invention is coupled to the inner lining (101) and the outer shell (105) is placed over it.

[0072] Also, FIG. 7 is a perspective view showing the back of a cooling helmet (100) applied to the present invention.

[0073] And FIG. 8 shows a cross-sectional view of a cooling helmet (100) applied to the present invention.

[0074] The effects of the cooling helmet (100) of the present invention configured as described above will be explained in more detail below.

[0075] First, the cooling module (110) disassembled as shown in FIGS. 1 and 2 is assembled as shown in FIGS. 3 to 6.

[0076] Afterwards, the cooling module (110) assembled as described above is assembled to the inner lining (101). At this time, the cooling module (110) is positioned at the rear of the inner lining (101), and the air ram (130) is assembled into the air ram insertion groove (102) of the inner lining (101). Then, the discharge port (131) located at the tip of the air ram (130) is assembled into the discharge port insertion hole (103) of the inner lining (101) to form the configuration as shown in FIG. 6.

[0077] Next, an outer shell (105) is assembled on top of the inner shell (101) assembled as described above to form a cooling helmet (100) as shown in FIGS. 7 to 9.

[0078] Afterwards, the cooling helmet (100) assembled as described above operates as follows.

[0079] The cooling helmet (100) applied in the present invention can be used when the motorcycle is not in operation or is in operation. When in operation, air is introduced through both the left intake port (122) and the right intake port (123) of the cooling helmet (100) to cool the hot part of the Peltier element (150), thereby increasing the efficiency of the cooling part. When not in operation, hot air is discharged through the exhaust port (171) of the module cover (170) via the internal cooler, which is a cooling heat sink (160) and a cooling fan (165).

[0080] In particular, the present invention utilizes the principle of efficiency where the cooling effect increases when external wind is continuously present around the Peltier element (150) in a natural aspiration method in which external air is naturally drawn into the left intake port (122) and the right intake port (123) during operation, thereby maximizing cooling efficiency by utilizing the natural wind inserted during operation.

[0081] In addition, the present invention is designed so that the roles of the left and right intake ports are different.

[0082] That is, when running while wearing the cooling helmet (100), the right intake port (123) generates cold air through the function of the blower heat sink (140) attached to the Peltier element (150), and the cold air generated here enters the inside of the helmet through the guide wing (141) and air ram (130) of the blower heat sink (140).

[0083] And the left intake port (122) serves to further lower the heat inside the cooling module (110) using the incoming air. That is, the cold air blower fan (145) rotates on the side of the Peltier element (150) to supply colder air to the inside, but additionally, the heat inside is further cooled by the natural wind passing through the left intake port (122), thereby allowing more efficient cooling air to be sent into the helmet.

[0084] At this time, a partition wall (126) is formed inside the module body (120) and the module cover (170) to prevent the air flowing into the left intake port (122) and the right intake port (123) from mixing with each other.

[0085] In addition, the control unit (180) applied in the present invention is connected to a Peltier element (150), and the Peltier element has a built-in temperature control program to prevent the temperature from dropping to 0°C according to the heat sink performance, thereby controlling the cooling helmet (100).

[0086] Meanwhile, the cooling helmet (100) is driven by the operation of the on / off switch (128) of FIG. 9 and the power supply from the battery (190), and the control unit (180) controls the temperature by applying the principles of the Peltier element (150) and the heat sink, and the cooling air is sprayed onto the crown of the head through the air ram (130) and the discharge port (131). At this time, the power supply may use an auxiliary battery (190) as described above, or current from a motorcycle may be used.

[0087] Finally, FIG. 9 shows a bottom perspective view of a cooling helmet (100) applied to the present invention.

[0088] The present invention described above selectively turns the power of the cooling helmet (100) on and off through an on / off switch (128).

[0089] In addition, if an auxiliary battery (190) that smoothly supplies 12V 5A power is optionally connected to the battery connection jack (127) formed on the bottom surface of the cooling module (110), anyone can easily carry it, and in particular, users (such as motorcycle delivery drivers) can use it conveniently in reality (can be worn on the waist).

[0091] As described above, the present invention supplies air cooled by the principle of a Peltier element and a heat sink to the crown of the head through an internal air path of the helmet. During operation, the efficiency of the cooling part can be further enhanced by cooling the hot part of the Peltier element through grooves on both sides of the helmet through which air can enter. When not in operation, the hot part is cooled through an internal cooling cooler. A power supply method utilizing the motorcycle's own current can be applied. The cooling module and the helmet body are physically separated to enable efficient assembly production and after-sales service. The Peltier element itself is a component whose safety has already been verified. The internal temperature control program ensures that there are no safety issues such as electromagnetic waves, fire, or explosion. The temperature inside the helmet is maintained at a comfortable level by the temperature control program of the control unit. The incoming gas is evenly distributed as cold air throughout the internal space, allowing for a cool and comfortable helmet to be worn even in hot summers. The invention provides the effect of maximizing the efficiency of external air intake into the helmet. Industrial applicability

[0093] The technical concept of the cooling helmet of the present invention is such that the same results can be repeated in practice, and in particular, by implementing such invention, it can promote technological development and contribute to industrial development, so it is sufficiently worthy of protection.
