Abstract

The present invention relates to a helmet and a method for dealing with an accident using the helmet, which the helmet includes: a helmet body part made of a resin having a semi-spherical space for receiving the head of a wearer; a light part arranged in the front of the helmet body part having LEDs mounted on a substrate to provide the wearer with lighting; a metallic heat radiator extending from the front of the helmet body part to the back thereof along the upper central line of the helmet body part and partially contacting the back of the substrate to discharge heat; a communication device part received in the helmet body part for dealing with communication and emergency circumstances; and a battery received in the helmet body part for supplying power to the communication part and light part. According to the present invention, the metallic heat radiator is integrated with the resinous helmet body part by injection molding of different materials, so that the heat generated from the LEDs of the light part is discharged upwards from the top of the helmet, thus preventing the wearer from being subjected to the discomfort caused by the heat generated from the LEDs.

First claim

The invention claimed is:

1. A safety helmet comprising:
a safety helmet body formed of a resin, for providing a semispherical space to accommodate the head of a human body;
a lighting part provided at a front side of the safety helmet body, for accommodating a substrate having an LED to provide light to a front side of a helmet wearer;
a metallic heat radiation part extending from a front side to a rear side of the safety helmet body along the center of an upper portion of the safety helmet body, for radiating heat while contacting a rear surface of the substrate;
a communication unit accommodated in the safety helmet body, for handling communication and occurrence of an emergency situation, automatically detecting the accident and reporting the accident when the accident occurs; and
a battery accommodated in a battery accommodation space, for supplying electric power to the communication unit and the lighting part,
wherein the communication unit comprises:
a microphone;
a camera that produces image data;
a memory that stores voice and image data;
a speaker; and
a control unit,
wherein the microphone and the camera provide voice and data communication based on detection of an accident by the comparison of information stored in the memory and the image data produced by the camera,
wherein the speaker, the memory and the control unit are configured to identify whether a wearer is conscious when an accident occurs based on an action of the wearer, and
wherein the emergency signal generator, reports if the wearer is unconscious.

2. The safety helmet of claim 1 , wherein the safety helmet body and the heat radiation part are coupled to each other through dissimilar injection-molding.

3. The safety helmet of claim 1 , wherein a plurality of heat radiation fins are provided at an upper portion of the heat radiation part, and protrusions are provided at a lower portion of the heat radiation part to be coupled to the safety helmet body.

4. The safety helmet of claim 1 , wherein two or more LEDs are mounted to the substrate, and the LEDs comprise reflection parts for limiting light emission angles such that the light emission angels of the LEDs are different from each other.

5. The safety helmet of claim 1 , wherein the communication unit further comprises:
images photographed by the camera and stored in the memory as still images of a predetermined period, that determine that an accident has occurred if there is no change in the images for a set time period.

6. The safety helmet of claim 1 , wherein the communication unit reproduces a voice signal stored in the memory through the speaker, and identifies whether the wearer's voice input through the microphone or an input through an input unit is present within a predetermined time period.

7. The safety helmet of claim 1 , wherein the communication unit further comprises:
a radio reception unit configured to receive a radio broadcasting signal;
a GPS memory configured to receive GPS data; and
a proximity sensor configured to detect a wearing state of the safety helmet, and stopping an operation of the communication means if the safety helmet is not worn.

8. A method of handling an accident using the safety helmet of claim 1 , comprising:
determining that the accident has occurred based on the absence of motion of the wearer that continues for a set time period or more;
outputting a voice signal to request a response of the wearer to determine occurrence of the accident and the conscious state of the wearer to an emergency signal generation unit; and
reporting information about the accident when the wearer is determined to be unconscious.

9. The method of claim 8 , wherein determining that the accident has occurred includes: detecting a motion of the wearer by detection images photographed by the camera at a predetermined period.

10. The method of claim 8 , wherein determining that the accident has occurred includes: detecting a motion of the wearer by using a gyro sensor.

11. The method of claim 8 , wherein outputting the voice signal includes:
outputting the voice signal input to the memory in advance through the speaker; and
identifying whether a voice of the wearer or an input signal through an input unit is input to determine that the wearer is unconscious if there is no input.

12. The method of claim 8 , wherein reporting information includes, using a mobile phone of the wearer to report via a Bluetooth communication.

13. The method of claim 8 , wherein the content of the accident report includes least one from a group consisting of a name, a gender, a blood type, an age, a chronic disease, a past disease history, and location information of the wearer.

14. A method of handling an accident using a safety helmet, comprising:
determining that an accident has occurred using a communication unit if a state in which there is no motion of a wearer continues for a set time period or more based on voice and data received from a microphone and a camera that detect the accident by a comparison of information stored in a memory and an image data produced by the camera;
outputting a voice signal through a control unit configured to determine the occurrence of an accident and a conscious state of the wearer based on an action of the wearer; and
reporting information of the accident stored in the memory to a rescue team through the emergency signal generation unit when the wearer is determined to be unconscious.

15. The method of claim 14 , wherein determining that an accident has occurred includes: a motion of the wearer is detected by detecting images photographed by the camera at a predetermined period.

16. The method of claim 14 , wherein determining that an accident has occurred includes: detecting a motion of the wearer using a gyro sensor.

17. The method of claim 14 , wherein outputting a voice signal further includes: inputting a voice signal to the memory in advance is output through a speaker; and identifying whether a voice of the wearer or an input signal through an input unit is input to determined when the wearer is unconscious if there is no input.

18. The method of claim 14 , wherein reporting includes that an accident is reported through connection to a mobile phone of the wearer using a Bluetooth communication.

19. The method of claim 14 , wherein the content of the accident report includes least one from a group consisting of a name, a gender, a blood type, an age, a chronic disease, a past disease history, and location information of the wearer.
