Image control device after Vehicular turn
Technical field
The steering indicating light that the present invention relates to a kind of vehicle controls, and is image control device after a kind of Vehicular turn concretely.
Background technology
Motor bike, automobile, battery-driven car have now become the walking-replacing tool of people's indispensability.
Needs turn round:
When people ride two-wheel car, later will looking at whether there is other vehicle after one's death, when looking back at, but have ignored the road of front side, thus the safety of image participant, bring harm to the life of people.
When driveing a car, head often will see back mirror according to the direction that will turn, and particularly for the first people by driving license, more easily there is the ignorance to dead ahead.
CN 202294580 U discloses a kind of visible auxiliary device for lane changing steering of automobile, turn to during lane change on rear side of the visual field of side to be directly presented on the intelligent display navigating instrument in car by external camera, improve turn to 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 indicating light controller and direction lever controller respectively, this connection mode, and when wheel steering, no matter steering angle size, navigating instrument is all opened, and steering indicating light is also lighted.
Summary of the invention
The object of the present invention is to provide image control device after a kind of Vehicular turn, there is the transmission of opening by video when turning to, directly can understand the situation after vehicle body from telltale.
The present invention realizes with following technical scheme:
Image control device after a kind of Vehicular turn, it is characterized in that, the both positive and negative polarity of described device is connected with the both positive and negative polarity of vehicle battery, and signal wire (SW) is connected with the output line of pole changer, wherein, in the jack of the lead-in wire insertion apparatus of camera.
When described turn signal swich is in conducting state, accumulator positive pole tension arrives described device through pole changer, and telltale uninterruptedly shows rear and moves or the image of stationary object, when described turn signal swich resets, and telltale time-delay closing.
Described relay selects its Chang Kaiduan of single group contact and capture card, the positive terminal of telltale is unified and connects.
Two groups of contacts selected by described relay, often organize the positive terminal separate connection of Chang Kaiduan independence and camera or capture card or telltale.
Described relay adopts and singly organizes contact, and its electric current must be greater than 10A.
Described relay adopts two groups of group independent contacts, and contact current must be greater than 6A.
The voltage of described relay is 12V, and contact also can be able to be two groups of contacts for single group contact.
The synchronous stopping of relay when described cond is to avoid flash light power-off.
The two ends shunt-wound capacitance device of described relay coil.
Described cond is when pole changer conducting, and because Vehicular turn Der Blink und Abblendschalter has: energising-power-off-energising-power down function, its capacity must ensure that the ON time of relay adhesive is longer than the power-off time of Der Blink und Abblendschalter.
Described cond is when pole changer cuts out, and its capacity must ensure the relay ON time of more than 3 seconds, and during to ensure steering wheel for vehicle return, vehicle is excessively not curved, to the loss of rear visible objects.
Described cond adopts more than 16V, and capacity is at 300uf-10000uf.
The magnitude of voltage of described cond is higher by 40% than former battery tension value.
Accompanying drawing explanation
Fig. 1 is the circuit detail drawing of image control device after a kind of Vehicular turn of invention.
Fig. 2 is the telltale assembling schematic diagram of image control device after a kind of Vehicular turn of invention.
Detailed description of the invention
Image control device after a kind of Vehicular turn of the present invention: described device comprises: capture card 1, telltale 3, cond 4, relay 5.
In FIG, capture card 1 signal input part welds a jack 6, capture card 1 mouth is connected with telltale 3, signal wire (SW) 10 is drawn in coil one end of relay 5, relay 5 other end is connected with the negative pole of described device and draws a negative line 9, relay 5 Chang Kaiduan is connected with capture card 1, telltale 3, and relay 5 common port also 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 providing power supply for camera 2.
In fig. 2, described capture card 1, cond 4 and relay 5 are placed in box 7, and telltale 3 is installed in described box 7 front, and described box 7 can be moistureproof.
In order to protect the corner of telltale 3, the position that telltale 3 is arranged in box 7 is lower than the plane of box 7.
Lateral layout jack 6 of described box 7, and stretch out an electrode line 8, negative line 9 and a signal wire (SW) 10.
