Description
Technical field
The present invention relates to drive training vehicle on-board electronic apparatus, and in particular to a kind of wired car fills amplifirer.
Background technology
It is the vehicle that driving school uses for religion training to drive training vehicle.Found in training field research is driven, because student practices for a long time
Sleepiness occurs in car, therefore sets external music player (such as mobile phone, tablet personal computer) to play music of releiving, but these are external
Music player is limited to volume less, and noise therefore is difficult to enjoy the enjoyment for playing music than larger when driving training vehicle traveling.
For this problem, technical staff's design specialized boom box equipment, but another problem is occurred in that again, external music
Device coordinates the appropriate big volume of sound equipment to play, and power consumption is larger, therefore technical staff's design specialized vehicle-mounted charging equipment.But it is actual
There are these equipment when using and arranging all is independent arrangement, and arrangement and use are all inconvenient, therefore designing a synthesis has
The training vehicle special product of driving that line audible music is played and charge function is integrated turns into new design direction.
The content of the invention
Amplifirer is filled it is an object of the present invention to provide a kind of wired car, vehicle-mounted charge and wired audio amplifier are integrated in one, are one
It is individual possess charging and music playback function drive training vehicle special product, i.e., can to external music player equipment charge,
Music can be played by the increase of wired audio amplifier again, arranged and using very convenient.
In order to realize the above object the technical solution adopted by the present invention is：A kind of wired car fills amplifirer, including vehicle-mounted fills
Electric unit and wired power amplifier unit；
Described vehicle-mounted charge unit includes charging circuit conversion module and conversion circuit output module, described charging electricity
Road conversion module is connected with automobile storage battery, and multichannel USB charging input ends mouthful are provided with described conversion circuit output module；
Described wired power amplifier unit is included from circuit conversion module and wired power amplifier module, described to convert mould from circuit
Block is connected with automobile storage battery, and the audio input change-over terminal of the external music player of connection is set on described wired power amplifier module
With the audio output of connection built-in player；
Described vehicle-mounted charge unit and wired power amplifier unit are placed on one piece of mainboard.
Further, described automobile storage battery output voltage is 12V, and described is that 12V turns 5V electricity from circuit conversion module
Road module.
Further, overcurrent protective device and too high temperature protection device are set on described vehicle-mounted charge unit.
Further, overcurrent protective device and too high temperature protection device are set on described wired power amplifier unit.
Further, two-way USB charging input ends mouthful are provided with described conversion circuit output module.
Further, described audio input change-over terminal is provided with multiple.
The technical effects of the invention are that：Product of the present invention is powered by automobile storage battery, and vehicle-mounted charge unit passes through the electricity that charges
Road conversion module changes into automobile storage battery 12V the voltage x current of multichannel USB charging input ends mouthful, meets external music dress
The charge requirement put；Wired power amplifier unit part has one from circuit conversion module, and it is given wired power amplifier module and powered, outside
The player for the audio output that the audio information data for putting music player passes through wired power amplifier module carries out music.
The problem of the invention reside in can solve the problem that the vehicle-mounted charge of external music player, it can solve the problem that again because driving training vehicle row
Cross the noise of journey generation and the small volume problem of external music player can not be heard, using by vehicle-mounted charge and wired sound
Case is integrated in one, be one possess charging and music playback function drive training vehicle special product, integral type special product arrangement
It is very convenient with using.
