Description
Technical field
The utility model relates to DVD, and it is switchable and can indicate the automobile-used dvd system of door contact interrupter situation to relate in particular to the read-out shows signal.
Background technology
Arrange the ceiling type DVD that the passenger watches for the back on the automobile at present, it is the main frame Play System shared signal used with the chaufeur at front row, back row passenger can not select video disc according to the hobby of oneself, in addition, back row's passenger loading tail gate has that not shut oneself be ignorant, but informs back row passenger by chaufeur according to the demonstration of the control system at front row, if when chaufeur is busy with handling other things like this, just might forget the back row passenger that passs on, traffic safety is caused a hidden trouble.In China Patent No. is ZL200820188478.1, and name is called " automotive headrest DVD ", patent documentation in a kind of automobile DVD is disclosed, its deficiency be can only the DVD player core of broadcast own signal, and can not indicate the door contact interrupter situation.
The utility model content
The utility model provides a kind of passenger can select still to watch video disc separately and have the dvd system of door contact interrupter indicator lamp with the front-seat video disc of seeing jointly, has solved back row passenger and can not play video disc separately and can only watch the problem of the video disc that front-seat main frame plays and car door to have not shutting back row passenger directly not know and the safety problem that causes.
Above technical matters solves by following technical proposal: a kind of automobile-used dvd system, comprise read-out, the DVD circuit card, the DVD player core, dvd system is provided with signal processor unit and door contact interrupter detecting device, indicator lamp, the DVD player core carries signal to give described signal processor unit, the vehicle main frame Play System carries signal to give described signal processor unit, signal processor unit carries signal to give read-out, signal processor unit is provided with change-over switch, playback switch, door detected status switch, the door contact interrupter detecting device carries signal to give signal processor unit, and the door contact interrupter detecting device carries signal to give indicator lamp.By the signalization processing equipment, realize allowing the passenger select to play signal that the vehicle main frame Play System sends and still play the signal that the DVD player core of native system transports, the passenger selects " change-over switch ", the signal of sending here for the vehicle main frame Play System that read-out shows, the passenger selects " playback switch ", the signal that transports for the DVD player core that read-out shows, when the passenger shuts down the utility model, read-out does not show, the passenger selects " door condition detection switch ", read-out shows the switch situation of car door, allow the signal conveys of the detected door switch situation of door switch detecting device give indicator lamp, read-out is when playing video disc, and the passenger also can learn the switch situation of door according to the indication of indicator lamp.
As preferably, the door contact interrupter detecting device carries signal to give indicator lamp by change-over switch.By change-over switch is set, can make indicator lamp not only can be used for showing the switch situation of car door, also available using it for anything else.
As preferably, when the door contact interrupter detecting device detected car door and do not close, the signal that the door contact interrupter detecting device is exported to described signal processor unit was a high level, and the door contact interrupter detecting device flows to the current signal that is of indicator lamp.
As preferably, change-over switch is a three position switch, the public termination indicator lamp of three position switch.First pin open circuit of three position switch, the crus secunda power connection of three position switch, the tripod of three position switch connects the signal output part of door contact interrupter detecting device.Different pin by change-over switch and the conducting of common port define the different purposes of indicator lamp, and the passenger can select indicator lamp be used for showing the switch situation of car door according to the wish of oneself, turns off the light, and still uses as illuminating lamp.
As preferably, indicator lamp is LED.The LED little power consumption, it is little to take up room.
As preferably, LED glows and high-brightness white-light.Select ruddiness indication car door not shut, redness is dangerous caution look, arouses people's attention easily, when LED is used as the illuminating lamp time spent, selects the white brightness of high brightness good, and cool colour light good visual effect.
The utlity model has following advantage, by the signalization processing equipment, and and the vehicle main frame Play System connect machine, thereby realized that the utility model both can play separately, can watch the signal of vehicle main frame Play System again, by give signal processor unit and indicator lamp with the door contact interrupter signal conveys, make when watching video disc, can also know the switch situation, eliminated potential safety hazard.
Description of drawings
Fig. 1 is a circuit diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.Referring to Fig. 1, the action of DVD circuit card control DVD player core, the DVD player core is given signal processor unit with signal conveys such as video/audios, the vehicle main frame Play System is also given signal processor unit with signal conveys such as video/audios, the door switch detecting device is also given signal processor unit with the information conveyance of detected door contact interrupter situation, signal processor unit is given read-out according to the Instruction Selection that the passenger provides with that road signal conveys, allow read-out show corresponding signal, if the passenger selects " broadcast " function, signal processor unit is given read-out with the signal conveys that the DVD player core transports, what also be that the utility model read-out plays is the signal that DVD player core own transports, if the passenger selects " switching " function, signal processor unit is given read-out with the signal conveys that the vehicle main frame Play System transports, what also be that the utility model plays is the signal that the main frame Play System transports, the passenger selects " door situation " function, signal processor unit is given read-out with the signal conveys that the door switch detecting device transports, what also be that the utility model plays is the switch situation of automotive door, if door does not shut, show on the read-out " car door does not shut as yet; please don't start vehicle ", if car door has been shut, show " door is also shut; have a good trip " on the read-out, what the door contact interrupter detecting device flowed to signal processor unit is high level signal, the door contact interrupter detecting device also is connected mouth with No. 3 pin of three change-over switch K, the open end of three change-over switch K i.e. No. 4 pin connects the positive pole that can glow with the light-emitting diode of high-brightness white-light, the negative earth of light-emitting diode, No. 2 pin power connection Vs of three change-over switch K, Vs is 4.5 volts, No. 1 pin open circuit of three position switch K, what the door contact interrupter detecting device was exported to three change-over switch K is current signal, when No. 1 pin of three change-over switch K is connected, light-emitting diode does not work, when No. 2 pin of three change-over switch K are connected, light-emitting diode is sent out high-brightness white-light, when No. 3 pin of three change-over switch K are connected, do not shut as car door, light-emitting diode glows, car door is shut, and light-emitting diode is not luminous.Therefore the passenger need show the switch situation of car door with light-emitting diode, No. 3 pin of three change-over switch K are connected, when the passenger does not want to have light to disturb, No. 1 pin of three change-over switch K is connected, when the passenger thinks to become clear in the car some, No. 2 pin of three position switch K are connected.
