In order to explain the present invention, its operational advantages, and the purpose achieved by the practice of the present invention, preferred embodiments of the present invention are exemplified and examined with reference thereto below.

First, the terms used in this application are only used to describe specific embodiments and are not intended to limit the present invention, and the singular expression may include plural expressions unless the context clearly indicates otherwise. In addition, it should be understood that the terms "comprise" or "have" in this application are intended to specify the presence of a feature, number, step, operation, component, part, or combination thereof described in the specification, and do not exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

In describing the present invention, if it is determined that a detailed description of a related known configuration or function may obscure the gist of the present invention, the detailed description will be omitted.

FIG. 1 is a schematic diagram showing the front of an integrated multi-functional smart safety helmet according to an embodiment of the present invention, and FIG. 2 is a schematic diagram showing the back of an integrated multi-functional smart safety helmet according to an embodiment of the present invention.

As illustrated in FIGS. 1 and 2, an integrated multi-functional smart safety helmet (1000) with a built-in battery according to one embodiment of the present invention includes a head protection unit (100), a notification unit (110), a first lighting unit (120), a first control unit (130), and a charging unit (140).

The head protection part (100) protects the wearer's head, and the notification part (110) is built into the head protection part (100).

The first lighting unit (120) includes at least one LED and is built into the head protection unit (100) to emit light.

The first control unit (130) is built into the head protection unit (100) and turns on or off at least one of the notification unit (110) or the first lighting unit (120).

The charging unit (140) supplies power to the battery.

Specifically, the notification unit (110) may include an alarm that emits an alarm sound. In addition, since the first lighting unit (120) is built into the head protection unit (100), there is no risk of it being removed by being caught on an obstacle.

In addition, the first control unit (130) includes at least one touch method among pressure-sensitive, electrostatic, and dial-type, including a switch button, depending on the usage environment, and the notification unit (110) can be turned on or off by the wearer's direct touch. Not only the notification unit (110) but also the first lighting unit (120) can be turned on or off by the first control unit (130). This can improve safety because the person wearing the integrated multi-functional smart safety helmet (1000) does not need to carry a separate adjustment device.

Additionally, a second lighting unit (150) may be further included.

The second lighting unit (150) is provided around the head protection unit (100) and surrounds the head protection unit (100) by including 1 to N LEDs.

In addition, it may further include a first chin strap (170) and a second chin strap (180).

The first chin strap (170) has a first connector (171) at the tip and is provided on one side of the head protection part (100).

The second chin strap (180) has a second connector (181) at the tip and is provided on the other side of the head protection part (100).

Specifically, the first chin strap (170) and the second chin strap (180) may be formed of silicone or polyurethane.

Typically, materials used in the chin straps of safety helmets are susceptible to contamination from sweat, dust, hand contact, and other sources. This can cause skin damage and bacterial infections. Therefore, if the first chin strap (170) and the second chin strap (180) are made of silicone or polyurethane, they can protect the wearer's skin and prevent bacterial infections.

FIG. 3 is a drawing showing a side view of an integrated multi-functional smart safety helmet according to an embodiment of the present invention.

As illustrated in FIG. 3, the integrated multi-functional smart safety helmet (1000) according to the present invention may further include a second control unit (190).

The second control unit (190) may be provided on at least one of the first chin strap (170) or the second chin strap (180) and may control the first lighting unit (120) or the notification unit (110).

Meanwhile, the first lighting unit (120) may have a luminance of 1,000 Lux or more. Accordingly, the second control unit (190) can control the on/off of the first lighting unit (120) and adjust the illumination according to the environment in which the wearer uses it, thereby maintaining an illumination intensity level suitable for safety standards.

In addition, the integrated multi-functional smart safety helmet (1000) according to the present invention may further include a first sensor unit (not shown) provided on at least one of the first chin strap (170) and the second chin strap (180). The first sensor unit may include a tension measuring sensor, and may be provided on the first chin strap (170) or the second chin strap (180) to measure tension generated according to an action of the wearer pulling the first chin strap (170) or the second chin strap (180).

In addition, the second control unit (190) can adjust the length of at least one of the first chin strap (170) or the second chin strap (180).

Specifically, it is preferable that the initial length adjustment value be set to be limited in inverse proportion to the size of the head protection part (100).

More specifically, when the wearer initially pulls at least one of the first chin strap (170) or the second chin strap (180) with a predetermined amount of tension, it is preferable that the larger the size of the head protection part (100), the smaller the limit of the length adjustment value.

This prevents the chin strap from being excessively tight around the wearer's chin.

Thereafter, the second control unit (190) can control the length of at least one of the first chin strap (170) or the second chin strap (180) to increase when the tension applied by the wearer to the first chin strap (170) or the second chin strap (180) is greater than the first tension, thereby increasing the length of the entire chin strap.

As described above, the length of the entire chin strap is increased by the first tension, but if it becomes excessively loose, it can be reduced again.

When the tension applied by the wearer is greater than or equal to the second tension and less than or equal to the third tension, the length of at least one of the first chin strap (170) or the second chin strap (180) may be reduced. In this case, the second tension and the third tension may mean a tension value smaller than the first tension, and the second tension may mean a tension value smaller than the third tension.

Accordingly, the length of the entire chin strap can be reduced, and by automatically adjusting the length of the chin strap as described above, the wearer can be prevented from wearing the integrated multi-functional smart safety helmet (1000) of the present invention excessively loosely or tightly, thereby providing the wearer with greater convenience and stability.

In addition, an integrated multi-functional smart safety helmet (1000) according to another embodiment of the present invention may further include a protective part (not shown).

The protective part is provided on both sides of the head protection part (100) and is formed with a predetermined width and a predetermined length in the downward direction, thereby having the effect of protecting the wearer's hearing from the notification part (110).

Meanwhile, a shock absorber may be provided inside the head protection unit (100). The shock absorber may include a polymer having a glass transition temperature lower than room temperature, specifically lower than 10°C, lower than 0°C, or lower than ??20°C. As a specific example of the shock absorber, it may be any one selected from among expanded polyurethane, expanded polysiloxane, and expanded polyolefin elastomer.

Specifically, the foamed polyurethane may be a polyurethane containing an aromatic group in its repeating unit, and has excellent elasticity, wear resistance, and processability. The foamed polysiloxane may be polydimethylsiloxane, and may be a cured polysiloxane containing a crosslinking group between the polymer main chains. The foamed polyolefin elastomer may be a polyethylene-propylene copolymer.

The above shock absorber can absorb shock more effectively by including a foam structure, and a known inorganic foaming agent or organic foaming agent can be used as a material for foaming the polymer, and a specific foaming method can be used without limitation in a known method, so a detailed description is omitted.

The foamed polyurethane, foamed polysiloxane, or foamed polyolefin elastomer according to the above specific example has excellent shock absorption and can effectively protect the head of a helmet wearer from external impact, and more preferably, a foamed polyolefin elastomer can be selected. Since the foamed polyolefin elastomer is included as a shock absorber, it can have excellent weather resistance and high reliability even when exposed to high temperatures and ultraviolet rays, and various additives included for stabilizing the shock absorber can be substantially omitted, so that it can provide high safety to the human body.

FIG. 4 is a block diagram illustrating the configuration of an integrated multi-functional smart safety helmet according to another embodiment of the present invention.

The operation of the integrated multi-functional smart safety helmet (1000) according to another embodiment of the present invention will be described through FIG. 4.

An integrated multi-functional smart safety helmet (1000) according to another embodiment of the present invention may further include a communication unit (160).

The communication unit (160) collects the location information of the wearer using the GPS (Global Positioning System) built into the head protection unit (100) and transmits the collected location information to an external device (server) to notify the wearer's current location in real time. In addition, the communication unit (160) can receive a predetermined signal from the external device and control the on/off of at least one of the notification unit (110) and the second lighting unit (150) based on the received signal.

Specifically, the built-in GPS function can support rapid and accurate rescue operations when the wearer is in a dangerous situation. Furthermore, when the communication unit (160) receives the signal, the notification unit (110) turns on to transmit an alarm sound, and simultaneously, the second lighting unit (150) turns on to emit light. This has the effect of audibly and visually alerting people around you of danger.

Alternatively, the communication unit (160) may be linked with an application. Accordingly, the communication unit (60) may automatically operate at least one of the notification unit (110) or the second lighting unit (150) based on the received information of the application.

At this time, the communication unit (160) controls the on/off of the second lighting unit (150) based on the received signal, and may cause the odd-numbered LEDs and even-numbered LEDs among the 1 to N LEDs of the second lighting unit (150) to operate alternately. Therefore, in the event of a dangerous situation, there is an effect of being able to provide greater alertness to the surroundings.

Meanwhile, the notification unit (110) and the first lighting unit (120) may be built into a module including the battery and may be integrated, and the module may be provided to protrude from the surface of the head protection unit (100).

Accordingly, since the notification unit (110) or the first lighting unit (120) is integrally built into the head protection unit (100) to notify of a dangerous situation, the wearer does not need to separately attach or detach it, and there is no risk of it coming off due to being caught on an obstacle.

In addition, according to another embodiment of the present invention, an integrated multi-functional smart safety helmet (1000) may further include a second sensor unit (not shown).

The second sensor unit may be provided in the head protection unit (100) and includes at least one sensor, and may recognize a target object entering within a predetermined distance based on the head protection unit (100).

Specifically, the second sensor unit may include a camera that recognizes relative coordinates and direction, which are distances from the second sensor unit to the target object.

More specifically, it is preferable that the camera be a wide-angle camera.

Additionally, it may include an inertial measurement device that recognizes changes in angle as the wearer's head rotates.

For this purpose, the present invention may further include a pattern display unit (not shown).

The pattern display unit can receive ID information from the wearer and generate a unique pattern based on the input ID information. Thereafter, the generated unique pattern can be displayed on one side of the head protection unit (100).

Accordingly, the second sensor unit can recognize the unique pattern of the other wearer, thereby recognizing the relative coordinates and direction of the other wearer, thereby enabling accurate location determination and preventing accidents such as collisions between each other.

Meanwhile, an integrated multi-functional smart safety helmet (1000) according to another embodiment of the present invention may further include a third control unit (not shown).

The third control unit can adjust the light irradiation range of the first lighting unit (120) based on the sensing result of the second sensing unit.

Specifically, when the first lighting unit (120) is turned on by the first control unit (130) and the third control unit does not receive a sensing result from the second sensing unit, it is determined that the target object does not exist, and the irradiation range of the first lighting unit (120) can be controlled to the first irradiation range.

Conversely, when the third control unit receives a sensing result from the second sensing unit, it determines that a target object exists and can control the irradiation range of the first lighting unit (120) to be narrower than the first irradiation range.

The target at this time may be an electric vehicle, and by controlling the irradiation range of the first lighting unit (120) to be narrower than the first irradiation range, a warning can be given to the approaching electric vehicle, thereby informing of danger and preventing an accident in advance.

FIG. 5 is a schematic diagram illustrating an integrated multi-functional smart safety helmet according to another embodiment of the present invention.

As illustrated in FIG. 5, the integrated multi-functional smart safety helmet according to another embodiment of the present invention covers the entire outer surface of the head protection unit (100) with the same material as the first chin strap (170) and the second chin strap (180), so that the module can be integrated with the head protection unit (100). At this time, the notification unit (110), the first lighting unit (120), the charging unit (140), and the communication unit (160) are integrated with the first chin strap (170) and the second chin strap (180), and can be assembled by being built into one module and covering the surface of the head protection unit (100).

In addition, the present invention is not limited to safety helmets, but can also be applied to helmets or hats.

Therefore, it can not only protect workers from dangerous and hazardous environments, but also protect ordinary citizens who use leisure sports such as bicycles, electric kick scooters, or motorcycles.

While preferred embodiments of the present invention have been described above, the present invention is not limited to the specific embodiments described above. That is, those skilled in the art to which the present invention pertains may make numerous changes and modifications to the present invention without departing from the spirit and scope of the appended claims, and all such appropriate changes and modifications should be considered equivalents and fall within the scope of the present invention.
