Following is embodiment of the present utility model:

Hands-free keyboard 1 is the distinctive parts of the utility model.Its internal circuit is made according to the keyboard circuit of matched handset 2.By cable 5, its signal wire (SW) is connected on the keyboard corresponding scanning line and sense wire of mobile phone., extra driving circuit can be added therebetween, also driving circuit can be according to circumstances do not added.

One end of cable 5 is edge connectors, by the opening of Hands-free key tray salver side, directly is inserted on the printed circuit board of hands-free keyboard.And the other end of circuit is inserted on the mobile phone on the private jack.This socket is installed on the appropriate location of mobile phone side, is connected internally at mobile phone on the circuit of cell phone keyboard.Like this, when pressing additional hands-free keyboard, the closed situation of hands-free keyboard just can be detected by the control circuit in the mobile phone, and makes the keyboard identical operations of mobile phone own.

When hands-free keyboard was worked, cell phone keyboard was not closed, and still can operate with cell phone keyboard.

Except hands-free keyboard, the utility model also in electric supply installation also is combined on the Earphone with microphone, transmitter and the car that had occurred in the past, makes the mobile phone operation when driving more convenient, safer.

Transmitter signal wire (SW) on the mobile phone 2 and horn cable also are by the same private jack 8 on the mobile phone, and pick out through cable 5.After picking out, tell a branch of branch line 9 from cable 5, receive on the transmitter 16 and loudspeaker 17 that is installed in appropriate location on the automobile, the calling voice signal of mobile phone output is emitted by loudspeaker through amplifying again, and realizes hands-free receiving calls.Near the transmitter, corresponding receiver J-Horner 18 is installed also onboard.For the time standby earphone receiving of not wishing that the people in the same car hears that the other side talks.Certainly, also can use on the mobile phone original receiver J-Horner to answer.

Except that mobile phone private jack 8 onboard, also have a plug 10, it is connected on the 12V power supply in the automobile by a voltage stabilizer 12.Voltage stabilizer changes into the 7.2V power supply that mobile phone is used to the 12V power supply in the car.When mobile phone inserts mobile phone dedicated seat, just and the interior power supply of car connected automatically.

Hands-free keyboard 1 can have a variety of mounting meanss onboard, and each one can select according to the hobby of oneself.

From the installation of hands-free keyboard 1, can divide and make A, B two big classes, every class has various ways again:

Category-A: fixing hands-free keyboard.

This class keyboard can be contained in the middle of the bearing circle according to user's requirement, or on the bearing circle handwheel.Also can be contained in the place of being convenient to operate, do not influence driving on the instrument carrier panel.This class keyboard need be done a spot of change to the specific features of automobile.

As an example, referring to Fig. 2: 1. on the bearing circle handwheel, 2. in the middle of the bearing circle, 3. be contained in position suitable on the instrument carrier panel.

Additional keyboard can be the keyboard special that embeds in the automobile component, or soft membrane keyboard.

On vehicle steering, can install hands-free transmitter and loudspeaker 16.Transmitter and receiver J-Horner 17 also are housed, and chaufeur can use Worn type earphone and transmitter.In addition,, can power to mobile phone,, prolong the life-span of battery of mobile phone to reduce the consumption of battery of mobile phone with the 12V power supply on the car by changer.

Transmitter, receiver J-Horner can also be installed in the tea water cup position.

Mobile phone can be placed on a certain fixing position, for example: front stall ash receptacle position, tea water cup position, suitable position on the instrument carrier panel.Will be when mobile phone is placed by the special mobile phone anchor fitting.In anchor fitting, special-purpose socket is arranged, with power lead by plug and cable connection to automobile.Mobile phone can not fixed yet, and only will couple together about signal wire (SW) and additional keyboard with cable.

Category-B: semifixed hands-free keyboard.

The integral body that the semifixed hands-free keyboard of mobile phone is made up of hands-free keyboard 1 and geometrical clamp behind thereof.It utilizes a geometrical clamp, be fixed on the instrument carrier panel of automobile or on the bearing circle, or automobile driver thinks to own suitable, does not influence ownly to observe road conditions, also do not influence on the position of oneself driving.After the keyboard holder installs, can take off refitting, generally no longer take off.

This class keyboard does not need automobile is changed.

Nut 19 on the keyboard holder is to be used for increasing the bed knife of clip on automobile.

Chaufeur can use head phone and transmitter.Or the loudspeaker of hands-free transmitter are installed in the appropriate location on automobile.For the mobile phone that has hand-free function, can not re-use head phone and transmitter.

In addition,, can power to mobile phone with the 12V power supply on the car equally,, prolong the life-span of battery of mobile phone to reduce the consumption of battery of mobile phone by voltage stabilizer and mobile phone support.

As an example, such as being contained on the control wheel, or be contained in gauge panel upper eyebrow left side or the like.Certainly, as installing, bearing circle is rotated a circle when above, should notice preventing that keyboard cable is wrapped on the bearing circle at needs according to Fig. 5.Say that generally at this moment this cable should be propped up by bearing circle and do inside and pick out.

Mobile phone 2 is placed on the mobile phone seat 13 that matches with its profile.

Mobile phone seat 13 is an integral body with its geometrical clamp 14 behind.

Nut 20 on the mobile phone geometrical clamp is to be used for increasing the bed knife of clip on automobile.

Mobile phone can be loaded onto mobile phone seat at an easy rate or take off from mobile phone seat.The mobile phone holder generally need not take off.

The mobile phone geometrical clamp can be used to be fixed on automobile driver to be thought to own suitable, does not influence oneself and observes road conditions, does not also influence on the position of oneself driving.

Chaufeur can use head phone and transmitter.For the mobile phone that has hand-free function, can not re-use head phone and transmitter.

In addition, can also use the firing unit cable, power to mobile phone by firing unit.Can save battery of mobile phone, prolong the life-span of battery of mobile phone.
