이하, 본 고안에 의한 차량용 핸드프리장치를 첨부도면에 도시한 실시예에 따라 설명하면 다음과 같다.Hereinafter, the vehicle hand-free device according to the present invention will be described according to the embodiment shown in the accompanying drawings.
본 고안의 차량용 핸드프리장치는 크게 핸드폰을 고정하는 본체(1)와, 핸드프리장치를 차체 내부에 고정시키기 위한 고정판(2)과, 상기 본체(1)와 고정판(2)을 상호 연결하는 연결부재(3)로 구성된다.The handfree device for a vehicle of the present invention has a main body (1) that largely fixes a mobile phone, a fixing plate (2) for fixing the handfree device inside the vehicle body, and a connection connecting the main body (1) and the fixing plate (2) to each other. It consists of the member 3.
상기 본체(1)는 일반적인 핸드폰의 형상에 대응할 수 있도록 소정의 면적 및 체적을 가지도록 된 것으로, 그 내부의 일측면에는 요홈(11)을 형성하고 이 요홈(11)에 자석(12)을 삽입 결합하여 그 외측면상에 핸드폰이 자력에 의해 고정되도록 하며, 또한 거치된 핸드폰의 충전 및 손으로 핸드폰을 들지 않고서도 통화를 할 수 있도록 회로기판(100)이 내장된다.The main body 1 is to have a predetermined area and volume to correspond to the shape of a general mobile phone, the groove 11 is formed on one side of the inside and the magnet 12 is inserted into the groove 11. By combining the mobile phone is fixed on its outer surface by the magnetic force, and also the circuit board 100 is built so that the charge of the mounted cell phone and the phone can be made without holding the phone by hand.
그리고 상기 본체(1)의 하단부에는 본체(1)에 핸드폰을 고정시키고자 할 경우 핸드폰이 하측 방향으로 낙하하지 않도록 지지턱(13)을 형성하고, 상기 본체(1)의 양측면에는 본체(1)에 거치된 핸드폰의 좌우 유동을 방지함과 아울러 핸드폰을 거치할 때 핸드폰의 위치를 안내하기 위한 가이드(14)가 형성된다.In addition, when the mobile phone is to be fixed to the main body 1 at the lower end of the main body 1, the support jaw 13 is formed so that the mobile phone does not fall downward, and the main body 1 is formed on both sides of the main body 1. In addition to preventing the left and right flow of the mobile phone mounted on the guide 14 is formed for guiding the location of the mobile phone when mounted.
또한, 상기 본체(1)의 하단에는 차량 내부의 시가잭에 접속시켜 핸드프리장치의 전원을 충당할 전원단자(15)가 연결되고, 그 일측에는 본체(1)에 거치된 핸드폰의 이어폰잭에 접속하기 위한 수신단자(16)가 연결되어 핸드폰으로 수신된 신호를 핸드프리장치로 전달하게 된다.In addition, a lower end of the main body 1 is connected to a cigar jack in the vehicle, and a power terminal 15 for supplying power to the hand free device is connected, and one side of the main body 1 is connected to an earphone jack of a mobile phone mounted on the main body 1. The receiving terminal 16 for connecting is connected to deliver the signal received by the mobile phone to the hand-free device.
즉, 차량을 운전 중인 운전자에게 외부기기(300)의 하나인 휴대폰에 수신신호가 전달되면, 운전자의 송수신버튼(17)의 조작에 따라 상기 외부기기의 휴대폰 신호는 오디오 및 데이터 입력검출부(140)에서 검출되며, 상기 오디오 및 데이터 입력검출부(140)는 검출신호를 각각의 CPU 제어부(130)와 오디오 데이터 입력(150)으로 전송하게 된다.That is, when the reception signal is transmitted to the mobile phone, which is one of the external devices 300, to the driver driving the vehicle, the mobile phone signal of the external device is input to the audio and data input detection unit 140 according to the operation of the driver's transmission / reception button 17. The audio and data input detector 140 transmits a detection signal to each CPU controller 130 and the audio data input 150.
CPU 제어부(130)는 상기 오디오 및 데이터 입력검출부(140)의 입력신호에 의해 PLL 방식의 VT전압으로 RF(무선 주파수) 발진 주파수가 제어되도록 PLL V/T제어부(170)를 제어하게 되고, 상기 CPU 제어부(130)로부터 제어신호를 입력받은 PLL V/T제어부(170)는 전압을 가변시켜 OSC 발진부(180)로 출력하게 되며, PLL V/T제어부(170)로부터 PLL신호를 입력받은 OSC 발진부(180)는 VT전압으로 가변하여 발진주파수를 CPU 제어부(130)로 다시 보내 원하는 정확한 주파수를 만들어낸다.The CPU controller 130 controls the PLL V / T controller 170 to control an RF (radio frequency) oscillation frequency with a PLL VT voltage by the input signal of the audio and data input detector 140. The PLL V / T controller 170 that receives the control signal from the CPU controller 130 outputs the voltage to the OSC oscillator 180 by varying the voltage, and the OSC oscillator that receives the PLL signal from the PLL V / T controller 170. 180 is variable to the VT voltage to send the oscillation frequency back to the CPU control unit 130 to produce the desired exact frequency.
한편, 오디오 및 데이터 입력(150)으로 전송된 신호는 상기 OSC 발진부(180)의 발진주파수와 혼합되어 RF 출력부(200)로 전송되며, RF 출력부(200)는 오디오 신호 및 데이터를 무선 주파수로 변조 증폭시켜 안테나(ANT)를 통해 차량의 FM 라디오로 송출하게 된다. 따라서, 외부기기(300)인 휴대폰으로 걸려온 전화를 차량의 FM 라디오로 수신하게 되며, 사용자의 음성은 본체(1)의 일단부에 형성된 마이크로폰(21)으로 송신되는 것이다.Meanwhile, the signal transmitted to the audio and data input 150 is mixed with the oscillation frequency of the OSC oscillator 180 and transmitted to the RF output unit 200, and the RF output unit 200 transmits the audio signal and data to a radio frequency. Modulated amplification is transmitted to the FM radio of the vehicle through the antenna (ANT). Therefore, the call received from the mobile phone, which is the external device 300, is received by the FM radio of the vehicle, and the voice of the user is transmitted to the microphone 21 formed at one end of the main body 1.
이때, 상기 본체(1)의 하단부에는 LCD 표시부(190)가 장착되어 핸드프리의 주파수를 표시해 주게 된다.In this case, an LCD display 190 is mounted at the lower end of the main body 1 to display the frequency of the hand free.
