Image control device after Vehicular turn
Technical field
The present invention relates to a kind of steering indicating light of vehicle controls, it is concretely image control device after a kind of Vehicular turn.
Background technology
Motorcycle, automobile, electric motor car have become the indispensable walking-replacing tool of people.
Needs turn round:
When people ride two wheeler, will later look at whether there are other vehicles after one's death, when looking back at, but have ignored
The road of front side, thus the safety of image participant, the life giving people brings harm.
When driveing a car, head will often see rearview mirror according to direction to be turned, especially for the people just taking driving license
For it is easier to there is ignorance to dead ahead.
CN 202294580 U discloses a kind of visible auxiliary device for lane changing steering of automobile, turn to and during lane change on rear side of side
The visual field directly displayed on intelligent display navigator in the car by external camera, improve steering and during lane change on rear side of
Visual range, convenient and practical, be conducive to safety driving tips.But it, steering driving mechanism connects steering lamp controller and side respectively
To rod controller, this connected mode, when wheel steering, no matter steering angle size, navigator is all opened, and turns to
Lamp is also lighted.
Content of the invention
It is an object of the invention to provide image control device after a kind of Vehicular turn, have when unlatching turns to and pass through video
Transmission, can directly from display understand vehicle body after situation.
The present invention is to be realized with following technical scheme:
Image control device after a kind of Vehicular turn, is characterized in that, the both positive and negative polarity of described device is with vehicle battery just
Negative pole connects, and holding wire is connected with the output lead of pole changer, wherein, in the jack of lead insertion apparatus of photographic head.
When described turning indicator control is in the conduction state, the diverted switch of accumulator positive pole tension reaches described device, shows
Show that device uninterruptedly shows the image of rear movement or stationary object, when described turning indicator control resets, display time-delay closing.
Described relay selects its normally opened end of single group contact to unify with capture card, the positive terminal of display and connect.
Described relay selects two groups of contacts, every group of normally opened end independently positive pole with photographic head or capture card or display
End independent connection.
Described relay adopts single group contact, and its electric current have to be larger than 10A.
Described relay adopts two groups of group independent contacts, and contact current have to be larger than 6A.
The voltage of described relay is 12V, and contact can also be able to be two groups of contacts for single group contact.
Described capacitor is to avoid the synchronization of relay during flash lamp power-off to stop.
The two ends shunt-wound capacitance device of described relay coil.
Described capacitor when pole changer turns on, because Vehicular turn flasher has:Energising power-off energising is disconnected
Electricity Functional, its capacity must assure that the ON time of relay adhesive is longer than the power-off time of flasher.
When pole changer cuts out, its capacity must assure that the relay ON time of more than 3 seconds to described capacitor, to protect
During card steering wheel for vehicle return, vehicle is not excessively curved, the loss to rear visible objects.
Described capacitor adopts more than 16V, and capacity is in 300uf -10000uf.
The magnitude of voltage of described capacitor is higher by 40% than former battery tension value.
Brief description
Fig. 1 is the circuit part drawing of image control device after a kind of Vehicular turn of invention.
Fig. 2 is the display assembling schematic diagram of image control device after a kind of Vehicular turn of invention.
Specific embodiment
Image control device after a kind of Vehicular turn of the present invention:Described device includes:Capture card 1, display 3, electric capacity
Device 4, relay 5.
In FIG, capture card 1 signal input part welds a jack 6, and capture card 1 outfan is connected with display 3, continues
Holding wire 10 is drawn in coil one end of electrical equipment 5, and relay 5 other end is connected with the negative pole of described device and draws a negative line
9, the normally opened end of relay 5 is connected with capture card 1, display 3, and relay 5 common port simultaneously draws an electrode line 8.
Described jack 6 comprises signal input part and power positive cathode end is integrated, and this power positive cathode end is used for as shooting
2 offer power supplys.
In fig. 2, described capture card 1, capacitor 4 and relay 5 are placed in box 7, and described box 7 front is installed
Display 3, described box 7 can be moistureproof.
In order to protect the corner of display 3, the position that display 3 is arranged in box 7 is lower than the plane of box 7.
Jack 6 of the lateral layout of described box 7, and stretch out 8, negative line 9 of an electrode line and a letter
Number line 10.
