Description
Technical field
The invention patent relates to a kind of vehicle mounted multimedia power-off protection apparatus, and in particular to automobile multimedia device does not power off
Do not restart circuit main board.
Background technique
With the development of society, automobile is more and more now, everybody likes installing automobile audio, visual parking device in the car
Navigation etc..Due to various blackmails, swindle, the criminal offences such as vehicle threaten people's lives steathily, it is also necessary to automobile data recorder is installed,
Evidence can also be being left at the crucial moment.
But automobile is when starting keyed ignition, the radios of interior some not reserve batteries, visual parking device navigation,
Sound equipment, automobile data recorder will whole cycle powers, cause the visual plot for temporarily failing, listening of reversing to be lost, also
It is possible that the automobile data recorder recorded loses several seconds crucial evidences.
Automobile since high current drops to automotive service voltage instantaneous very low, causes electricity in the moment for starting keyed ignition
Pressure is not enough to power to equipment such as the radio of automobile, visual parking device navigation, sound equipment, automobile data recorders, so that equipment is shut down, when
After automotive ignition success, voltage restores normal, and equipment turns back on operation.
Patent content
Problems solved by the invention be to provide it is a kind of can allow automobile when lighting a fire starting, it is the radio of automobile, visual
Reversing navigation, sound equipment, the equipment such as automobile data recorder will not the automobile multimedia device of cycle power do not power off and do not restart circuit master
Plate.
In order to achieve the above object, technical solution used by the invention patent is: automobile multimedia device does not power off not
Restart circuit main board, including vehicle-mounted multimedia equipment；Often electric power supply, ACC electricity are provided on the vehicle-mounted multimedia equipment
Source line and ground line；
Two poles that control current direction is flowed to vehicle-mounted multimedia equipment by ACC control terminal are in series on the ACC power supply line
Pipe；Capacitor is provided between the diode and ground line；The anode of the capacitor is electrically connected with diode, and the capacitor is born
Pole is electrically connected with ground line.
Specifically, the diode uses 5399 diodes.
Specifically, the capacitor uses the capacitor of 25V1000uf.
Specifically, the vehicle-mounted multimedia equipment includes radio, visual parking device navigation, sound equipment, automobile data recorder.
Beneficial effects of the present invention: automobile multimedia device of the present invention, which does not power off, does not restart circuit main board, can
Avoid automobile when starting keyed ignition, the radio of interior some not reserve batteries, visual parking device navigation, sound equipment, row
The cycle power of vehicle recorder；It can be avoided the visual plot for temporarily failing, listening of reversing simultaneously to lose；It can guarantee
Automobile data recorder normal sustained service guarantees that automobile data recorder can continue to record driving conditions.
Detailed description of the invention
Fig. 1 is that automobile multimedia device does not power off the circuit block diagram for not restarting circuit main board in the embodiment of the present invention.
Specific embodiment
The specific embodiment of the invention patent is described in detail with reference to the accompanying drawing.
As shown in Figure 1, the automobile multimedia device does not power off and do not restart circuit main board in the embodiment of the invention patent,
Including vehicle-mounted multimedia equipment；Often electric power supply, ACC power supply line and ground connection are provided on the vehicle-mounted multimedia equipment
Line；
Two poles that control current direction is flowed to vehicle-mounted multimedia equipment by ACC control terminal are in series on the ACC power supply line
Pipe；Capacitor is provided between the diode and ground line；The anode of the capacitor is electrically connected with diode, and the capacitor is born
Pole is electrically connected with ground line.
Specifically, the diode uses 5399 diodes.Specifically, the capacitor uses the capacitor of 25V1000uf.Tool
Body, the vehicle-mounted multimedia equipment includes radio, visual parking device navigation, sound equipment, automobile data recorder.
During the work time, since automobile is in the moment for starting keyed ignition, since high current is by automotive service voltage wink
Between drop to it is very low；Vehicle mounted multimedia is flowed to by ACC control terminal due to being in series with control current direction on the ACC power supply line at this time
The diode of equipment；Capacitor is provided between the diode and ground line；The anode of the capacitor is electrically connected with diode, institute
The cathode for stating capacitor is electrically connected with ground line.When ACC power line voltage is normal, capacitor charging；When the wink for starting keyed ignition
Between voltage reduce when, capacitor electric discharge, capacitor provides enough voltage for vehicle-mounted multimedia equipment at this time.To avoid voltage not
Foot causes radio, visual parking device navigation, the sound equipment, automobile data recorder shutdown of automobile；Therefore it is vehicle-mounted more to avoid automotive ignition
Media device is restarted.
In conclusion automobile multimedia device of the present invention does not power off and do not restart circuit main board, automobile can be avoided
When starting keyed ignition, the radio of interior some not reserve batteries, visual parking device navigation, sound equipment, automobile data recorder
Cycle power；It can be avoided the visual plot for temporarily failing, listening of reversing simultaneously to lose；It can guarantee driving recording
Instrument normal sustained service guarantees that automobile data recorder can continue to record driving conditions.
Although being described in detail in conjunction with specific embodiment of the attached drawing to the invention patent, should not be construed as pair
The restriction of the protection scope of this patent.In range described by claims, those skilled in the art are without creative labor
The dynamic various modifications that can be made and deformation still fall within the protection scope of this patent.
