Description

A kind of vehicle-carried hands-free telephone incoming call and information display device

Technical field

The utility model relates to incoming call and information detecting, incoming call and information display technology, relates in particular to a kind of vehicle-carried hands-free telephone incoming call and information display device.Display screen does not have displaying contents at ordinary times, perhaps show simple information such as some times, local operating state indication, as when incoming call, display screen promptly provides incoming call number and for information about, the user can obtain these information very easily, and makes corresponding processing.

Background technology

Almost the traffic safety code of All Countries is all stipulated in the world, does not allow on the run to make a phone call, because in the driving procedure, a cell-phone is conversed, and has a strong impact on driving safety.

Along with social development, people's rhythm of life is day by day accelerated, and people's drive time is more and more, and is interpersonal, and linking up by phone has become topmost communication way at present.Like this, the contradiction that is difficult to be in harmonious proportion of driving and answering the call and forming, so the cell-phone conversation though rules do not allow to drive, in fact implementation dynamics is but not strict.

Recently, the implementation dynamics of traffic law has all been strengthened in various places, and the local regulation of complementarity has all been formulated in most of places, with strict these regulations, has occurred a large amount of vehicle-carried hands-free telephones in the market.Wherein general with on-vehicle Bluetooth hands-free phone based on Bluetooth technology, the on-vehicle Bluetooth hands-free phone is based on blue-tooth technology, be connected with user's mobile phone, carry out the voice-and-data transmission, after using this hands-free phone, during user's communication, can both hands not from steering wheel, with the same conversation of occupant's speech, improved the fail safe of driving with usually greatly.

The user checks incoming information for convenience, also release some on the market and had the function of caller identification, some type also can be with the address list synchronization in the phone to vehicle-carried hands-free telephone, but these types all have a same shortcoming, content displayed is not easy to observation, often needing to change direction of visual lines could observe, and is unfavorable for safe driving.In view of the situation, the motivation of following utility model is made in designer's germinating.

The utility model content

The technical problems to be solved in the utility model provides a kind of vehicle-carried hands-free telephone incoming call and information display device that direction of visual lines just can be observed that do not need to change.

For solving the problems of the technologies described above, the utility model by the following technical solutions:

Vehicle-carried hands-free telephone incoming call and information display device, comprise a bluetooth communication module, one audio frequency amplifier, one loud speaker, one pick-up, one display screen, one group of button and vehicle-carried hands-free telephone or user mobile phone that is used for set conversation volume and function setting is connected after described bluetooth communication module and vehicle-carried hands-free telephone or the user mobile phone coupling; Described bluetooth module is connected by the signal transmission successively with described audio frequency amplifier, loud speaker and pick-up, and described bluetooth communication module is connected with display screen by the feedback signal of the information contents such as telephone number of the incoming call of user's mobile phone; Described display location in this display unit upper surface, it is characterized in that: described display unit is arranged on the top of planting the control instrument desk in the car, and correspondence is provided with projection display equipment on the shield glass above the projection of its light.

Described display unit is a LED display.

Described this device also comprises a lithium cell charging circuit.

Introduce the operation principle of vehicle-carried hands-free telephone incoming call and information display device below, bluetooth communication module is responsible for the communication of vehicle-carried hands-free telephone and user mobile phone, after the pairing of user's operating handset and bluetooth module was connected, all incoming calls all can be transferred on the bluetooth module automatically.Bluetooth module sends the voice model of conversation to audio frequency amplifier, model is amplified the rear drive loud speaker take place, so that the user need not also can hear the dialog context that the other side sends clearly near loudspeaker.User's voice after the conversation pick-up is converted to the signal of telecommunication, sends bluetooth communication module to, and bluetooth communication module sends to user's mobile phone again, and mobile phone sends to an other side of conversation again.The information of the telephone number of incoming call, the driving through overdrive circuit is presented on the display screen.

Its working method is: before the user uses, need earlier on-vehicle Bluetooth hands-free phone and mobile phone to be carried out Bluetooth pairing, finish after the pairing action, all incoming calls of mobile phone all can be transferred on the vehicle-carried hands-free telephone.

When the incoming call incoming call, mobile phone sends to the on-vehicle Bluetooth hands-free phone by bluetooth communication with signal, and the on-vehicle Bluetooth hands-free phone promptly sends incoming ring tone, reminds the user that incoming call is arranged.Simultaneously, promptly show caller ID on the on-vehicle Bluetooth hands-free phone display screen, during the Direct observation screen content, screen content is anti-showing, and is promptly opposite with normal demonstration, because the display screen content displayed is higher than ambient light, under the reflex of front windshield, form a drop shadow effect because the display screen displaying contents is reverse, through the reflection after both projectable be the content that forward can be read.

The user can determine to connect or hang up by the reading to telephone number, or other corresponding operatings.

Adopt the product of the utility model technology, be positioned over the suitable position of front windshield, when incoming call or information demonstration, front windshield reflects to form projection to display contents, the motorist is with normal driving sight, get final product easy-to-read for information about, need not to divert sb.'s attention, effectively improve traffic safety.

The utility model has following beneficial effect: the 1) embodiment that relates to of this utility model, can be applied to multiple car handsfree phone system, and include but not limited to the on-vehicle Bluetooth hands-free phone; 2) not changing the original structure that relates to of automobile, do not influence automobile original function and use habit, can be that the user brings reliable life support with very low cost.
