Abstract
The utility model discloses a kind of liquified gas automobile delay control system, and key switch is connected with distributing box by slug relay.The utility model is because add slug relay, and when key switch turns off, distributing box does not turn off immediately, can time delay (as 10 seconds), and allow the gas remained in pipeline thoroughly run out of, vehicle is just static, greatly improves the safety of liquified gas automobile.
Description
Technical field
The utility model relates to a kind of liquified gas automobile delay control system.
Background technology
Liquified gas automobile combustion completion, and have a series of emission-control equipment, carbonic oxide in exhaust, hydro-carbon equal size are atomic, meet automobile waste discharge regulation the strictest in the world.Because various security insurance valve installed by automobile, tightly and effectively ensured that car all can not presence of fire or explosion accident under various unforeseen circumstances, the safety performance of its height has obtained generally acknowledging of the world.
But, as shown in Figure 1, key switch 10 is direct or be connected with distributing box 20 by fuse 30, and namely the power supply of start distributor 20 is controlled by key switch 10 for the engine control principle of current liquified gas automobile, when key switch 10 power cutoff, distributing box 20 directly dead electricity and thereupon closing, engine stop runs, and vehicle stops travelling immediately, having residual gas like this stays in pipeline, also have little time to consume completely, cause explosive sound, and cause potential safety hazard.
For this problem, the present inventor develops a kind of liquified gas automobile delay control system specially, with time delayed turn-off distributing box, the gas in pipeline is thoroughly run out of, and improve safety, this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of liquified gas automobile delay control system, time delayed turn-off distributing box, improves the safety of liquified gas automobile.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of liquified gas automobile delay control system, key switch is connected with distributing box by slug relay.
Wherein, described slug relay adopts 4 pin relays, and two input pins connect key switch and negative pole respectively, and two other secondary contact connect power supply and distributing box respectively.
Secondary contact of described slug relay connect power supply by fuse.
Adopt after such scheme, the utility model because add slug relay, when key switch turns off, distributing box does not turn off immediately, can time delay (as 10 seconds), allows the gas remained in pipeline thoroughly run out of, vehicle is just static, greatly improves the safety of liquified gas automobile.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of existing liquified gas automobile control system;
Fig. 2 is the schematic diagram of the utility model control system.
Detailed description of the invention
As shown in Figure 2, a kind of liquified gas automobile delay control system that the utility model discloses, key switch 1 is connected with distributing box 2 by slug relay 4, i.e. newly-increased slug relay 4 between key switch 1 and distributing box 2.Like this, key switch 1 is utilized to control slug relay 4 coil, the contact of 10 seconds slug relays 4 controls start distributor 2, distributing box 2 power supply is changed into slug relay 4 secondary contact to control, instead of directly controlled by key switch 1, namely when turning off key switch 1, distributing box 2 is not closed immediately, but just turn off after 10 seconds, thus allow residual gas thoroughly run out of, fully can use combustion gas, economize energy, avoid waste, avoid remaining in the explosive sound that the gas in pipeline causes when key turns off suddenly, remove potential safety hazard, greatly improve the safety of liquified gas automobile.
Particularly, as shown in Figure 2, slug relay 4 adopts 4 pin relays.In two input pins, 3 pin connect key switch Isosorbide-5-Nitrae pin and connect negative pole, and namely slug relay 4 coil is controlled by key switch 1.In two other secondary contact, 1 pin connects 12V power supply by fuse 3, and 2 pin connect distributing box 2.When key switch 1 is opened, slug relay 4 coil obtains electric, 1,2 pin contact switchs close, now distributing box 2 is opened, vehicle brings into operation, and when key switch 1 is closed, slug relay 4 coil losing electricity, but contact switch can not disconnect immediately, and after being through time delay in 10 seconds, just disconnect, i.e. distributing box 2 loop just meeting dead electricity after 10 seconds, distributing box 2 now just can turn off, vehicle is out of service, and through these 10 seconds, the gas remained in pipe was consumed completely, thus avoids the problem because of the potential safety hazard having gas residue to cause in pipe.
In a word, the utility model utilizes the time of 10 seconds time delayed turn-offs, the gas remained in pipeline is thoroughly run out of, reduce the waste of the energy, avoid turning off key switch 1, staying the explosive sound sent in pipeline because there being residual gas, avoiding because residual gas is stayed in pipeline, and the potential safety hazard caused.
