The back fog light control circuit of the embodiment of the present invention, the magnet coil of the electromagnetic relay switch in fog tail lamp loop is serially connected in by the power supply in adverse-weather lamp loop and the loop of switch, like this, only when the conducting of adverse-weather lamp loop, namely when adverse-weather lamp is bright, relay switch in fog tail lamp loop just can close and form loop, thus meet adverse-weather lamp bright time just can open the requirement of fog tail lamp, circuit realiration is simple.
In addition, in alarm loop, be connected in series one often driven electromagnetic relay and a normally closed electromagnetic relay, the conducting of this normally opened relay whether by fog tail lamp conducting whether and the folding of door contact interrupter jointly determine, this normally closed electromagnetic relay and ACC power supply form loop, like this, when ignition lock is closed or ignition key extracts, when car door do not close, fog tail lamp is opened, alarm loop conducting is made, play the effect of warning of reporting to the police, circuit structure is simple and practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of the back fog light control circuit according to the embodiment of the present invention.
Detailed description of the invention
For enabling above-mentioned purpose, the feature and advantage of invention more become apparent, below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Set forth a lot of detail in the following description so that fully understand the present invention, but the present invention can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when without prejudice to doing similar popularization when intension of the present invention, therefore the present invention is by the restriction of following public specific embodiment.
Shown in figure 1, in this embodiment, earth point G is the earth point of whole fog lamp control system, adverse-weather lamp loop is by adverse-weather lamp power supply 1, adverse-weather lamp master cock and adverse-weather lamp 5 compose in series successively, adverse-weather lamp master cock controls the whole open circuit in adverse-weather lamp loop or the state of conducting, in this preferred embodiment, adverse-weather lamp master cock is the second electromagnetic relay switch J2 of open type, the closure state of this second electromagnetic relay switch J2 is decided by the conducting state of adverse-weather lamp control loop, adverse-weather lamp control loop is by controlling power supply 2, position lamp K switch 1, the magnet coil of adverse-weather lamp K switch 2 and the second electromagnetic relay switch J2 composes in series successively, when adverse-weather lamp opened by needs, position lamp K switch 1, adverse-weather lamp K switch 2 closes, adverse-weather lamp control loop is conducting loop, the magnet coil energising of the second electromagnetic relay switch J2, then the second electromagnetic relay switch J2 closes, adverse-weather lamp loop is conducting state, then adverse-weather lamp 5 is energized and opens.Certainly, in other examples, adverse-weather lamp master cock can be directly also position lamp K switch 1 and the adverse-weather lamp K switch 2 of series connection, directly controls the open circuit in adverse-weather lamp loop or the state of conducting by these two switches.
Fog tail lamp loop is by fog tail lamp power supply 3, rear fog lamp switch K3, first electromagnetic relay switch J1 of open type, fog tail lamp 6 and being composed in series successively, the open circuit in fog tail lamp loop or the state of conducting is jointly determined by the state of rear fog lamp switch K3 and the state of the first electromagnetic relay switch J1, namely whether fog tail lamp is opened, wherein, the magnet coil of the first electromagnetic relay switch J1 is attempted by the two ends of adverse-weather lamp 5, like this, by adverse-weather lamp power supply 1, the magnet coil of adverse-weather lamp master cock and the first electromagnetic relay switch J1 has composed in series fog tail lamp control loop successively, thus, only have when adverse-weather lamp master cock closes, when adverse-weather lamp loop is conducting state, namely adverse-weather lamp is opened, fog tail lamp control loop is the state of conducting, electric current is had in the coil of the first electromagnetic relay switch J1, first electromagnetic relay switch J1 closes, after rear fog lamp switch K3 is closed, fog tail lamp just can be opened, thus under ensure that the state of only opening at adverse-weather lamp, fog tail lamp just can be opened.
In addition, in this embodiment, also has alarm loop, it is by fog tail lamp power supply 3, 3rd electromagnetic relay switch J3 of open type, 4th electromagnetic relay switch J4 of closed type and annunciator JB composes in series successively, the first alarm control loop is composed in series by the magnet coil of ACC power supply 4 and the 4th electromagnetic relay switch J4, by fog tail lamp power supply 3, rear fog lamp switch K3, the magnet coil of the 3rd electromagnetic relay switch J3, one-way conduction diode D1 and door contact interrupter 7 compose in series the second warning control loop successively, the conducting direction of one-way conduction diode D1 is that the magnet coil of the 3rd electromagnetic relay switch J3 flows to door contact interrupter 7, when car door is not closed, door contact interrupter closes, the starting state of annunciator is controlled by the conducting state of two alarm loops.When ignition lock is closed or ignition key taking-up, now ACC power supply 4 is not powered, the magnet coil no power of the 4th electromagnetic relay switch J4 that contact is normally closed, the contact of the 4th electromagnetic relay switch J4 is still closure state, if now left-hand door or right car door are not closed, then left-hand door K switch 4 or right door switch K5 are closure state, if rear fog lamp switch K3 is closure state, the then coil electricity of the 3rd electromagnetic relay switch J3, the closing of contact of the 3rd electromagnetic relay switch J3, fog tail lamp siren horn JB is powered by fog tail lamp power supply 3, send alerting signal, thus realize when ignition lock is closed or ignition key taking-up, when chaufeur does not close car door, if fog tail lamp is in open mode, then send alerting signal.
In the present embodiment, adverse-weather lamp is two fog lamps L1, L2 in parallel, fog tail lamp is two fog lamps L3, a L4 in parallel and fog tail lamp indicating device L5, in this embodiment, fog tail lamp indicating device L5 is indicator lamp, can arrange on the control panel, the state of display fog tail lamp, door contact interrupter is two door switchs in parallel, but be only example herein, it will be appreciated by persons skilled in the art that can be as required, arrange quantity and the connection mode of adverse-weather lamp, fog tail lamp and door contact interrupter, the present invention's contrast does not limit.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
