The present invention relates to a safety helmet equipped with a transmission/reception function, and more particularly, a personal communication device and a speaker and microphone capable of short-range wireless communication are integrated into a safety helmet used for various purposes such as sports, work, and rescue. It relates to a safety helmet equipped with a transmission/reception function that is configured to enable a call while the wearer of the safety hat performs other tasks with both hands.

With the increase of the sports population, sports activities that are active outdoors are increasing day by day. In particular, in the case of sports activities using equipment, the wearing of various types of safety devices for the purpose of physical safety is increasing. There is a trend to wear safety tools.

In particular, when working in a construction site or in a harsh environment as well as sports activities, the wearing of a helmet (helmet) is increasing to protect the head, which is the most important part of the body.

On the other hand, as the Internet environment increases and wireless communication functions become a daily life, personal communication devices can be used anytime, anywhere, while using the Internet using personal communication devices, listening to music and other broadcasts even in environments where outdoor sports activities or work are performed. The use of personal communication devices such as, etc. is also on the rise rapidly.

Accordingly, wireless communication technology that enables personal communication devices to be used anytime, anywhere is mounted on various devices to increase user convenience.

In particular, in the case of the helmet belonging to the present invention, in order to reduce the inconvenience of taking off the helmet worn for voice calls, information transmission and reception, listening to music, etc., or holding a personal communication device with one hand during exercise or performing a task, There is a trend that various technologies for helmets equipped with wireless communication functions are being developed.

Looking at the case of the wireless communication technology applied to the helmet belonging to the present invention, as an example, the'Bluetooth Bicycle Helmet' of Korean Patent Registration No. 10-1176106 was conceived, and functions such as listening to music, mobile phone calls, intercoms, etc. Inventions have been devised to enable convenient use of various external devices.

However, such a Bluetooth bicycle helmet has a microphone and a speaker configured in the form of an ear microphone phone or mounted on an auxiliary case for fixing a speaker that is detachably mounted on a safety helmet.

In addition, as another conventional embodiment, a “hands-free helmet capable of wireless communication with a mobile communication terminal” of Korean Utility Model Registration No. 20-325765 has been devised.

The'hands-free helmet capable of wireless communication with a mobile communication terminal' of the above design also receives a short-range wireless communication signal from a short-range wireless communication relay module on the helmet and outputs a voice signal, and the voice signal spoken by the user and a command input by the user are short-range. A hands-free module that converts into a wireless communication signal and transmits it to a short-range wireless communication relay module, wherein the hands-free module includes a transceiver for transmitting and receiving a short-range wireless communication signal, a speaker installed in a position adjacent to the user's ear and outputting a voice signal. , A microphone installed in a position adjacent to the user's mouth to convert the voice signal spoken by the user into an electronic signal, and a call start and end button installed in a position adjacent to the user's left ear to receive a call start and end command from the user. It was made in the configuration.

Accordingly, the user can make a call by pressing the call start button and the end button while wearing the helmet, so that the conventional inconvenience caused by wearing the helmet can be solved.

As another conventional example, the “Bluetooth bicycle helmet” of Korean Utility Model Registration No. 20-0487331 has been devised.

The'Bluetooth Bicycle Helmet' is capable of wireless communication with an external device and includes a Bluetooth module with a built-in speaker, a safety helmet having a module storage unit in which the Bluetooth module is accommodated in the lower left and right sides, and a Bluetooth module accommodated in the safety helmet It consists of a configuration including a rear cover that is mounted in a form that wraps the side and rear of the safety helmet so that the safety helmet can be fixed, and the user wearing the helmet can use external devices such as mobile phones, MP3s, and navigation devices in a Bluetooth method, reducing hand restraint time. It is configured to increase the convenience of use of external devices.

In this way, all conventionally devised helmets with Bluetooth or hands-free functions are developed in the form of simply attaching or embedding previously developed parts or devices to the helmet to achieve the same purpose, thus complicating the configuration of the device, There is a risk that it can be easily removed or lost, and even if it is configured integrally with the helmet, it is difficult to accurately hear the sound output from the speaker depending on the usage environment.

When the wearer wearing the helmet 100 according to the present invention receives an incoming signal from an external communication device 200 such as a mobile phone or a walkie-talkie, the external communication device simply presses the call button of the operation display unit provided on the outer surface of the main body. And the call status is maintained.

Therefore, the voice signal transmitted from the external device is transmitted to the MCU through the transceiver of the Bluetooth module, and the MCU converts the received voice signal into an electrical signal and transmits it to the speaker. As the vibration is generated, the vibration signal is transmitted to the inner skin of the main body to generate an acoustic signal, so that the wearer of the helmet can clearly hear the acoustic signal generated inside the main body.

In addition, the voice made by the wearer of the hard hat is received by the microphone, an electrical signal is transmitted to the MCU, and transmitted to the external communication device through the transceiver, thereby enabling a voice call with an external communication device user.

In addition, the image captured by the camera provided on the outer upper surface of the main body is stored in the memory card mounted on the memory card slit provided at one side of the operation display unit, and the image stored in the memory card is controlled by the external communication device through the control of the MCU. Not only can it be configured to be automatically transmitted to the computer, but it also provides convenience in handling incidents and accidents by allowing the images stored in the memory card to be reviewed through a computer after being separated from the main body and after work or after handling an incident.

In the detailed description of the present invention described above, since the signal transmission/reception and data processing technology of the short-range wireless communication technology in which calls are made between different communication devices can be easily implemented by a person skilled in the art using known technologies or components, detailed descriptions thereof will be omitted. .
