Abstract
The invention discloses an inflowing water protection device of an automobile engine. The inflowing water protection device of the automobile engine consists of a power supply, a processor, a water depth displayer circuit, a resistance probe, a green light-emitting diode, a buzzer, a red light-emitting diode, a relay A, a relay B, a trigger switch A, a trigger switch B and a circuit switch which respectively forms a water depth detecting and warning circuit, a water depth displaying system and an engine protection circuit. The resistance probe is fixed at the bottom of an automobile, and the height of the resistance probe is slightly lowered than that of an exhaust pipe port of the automobile. The inflowing water protection device of the automobile engine is simple in structure, convenient to use and capable of learning the changes of water depth in real time when the automobile wade into water and avoiding severe damage of the automobile engine due to starting again after the water enters the engine.
Description
Technical field
The present invention relates to a kind of automobile protective device, be specially a kind of motor car engine water inlet protective equipment.
Background technique
The fordability of general automobile is limited.It is abundant to have arrived summer rainwater, is easy to produce darker ponding at the low-lying place of road, paddles rashly not knowing under the situation of the depth of water, be easy to because of water inflow of the engine stops working, and this moment once more ignition trigger be easy to make motor badly damaged.
One Chinese patent application 200910007955.9 discloses a kind of wading alarm device for automobiles; This device immerses when paddling and makes the warning circuit energising in the water through being installed in probe at the bottom of the car; Sending chimes of doom reminds the driver not paddle; This apparatus structure is simple, but function singleness and do not possess the real-time depth of water and report to the police and prevent the function that motor damages because of restarting.
Summary of the invention
The technical problem that the present invention will solve; Provide a kind of motor car engine water inlet protective equipment; This device can be understood the variation of the depth of water in real time when automobile is paddled; Prevent engine misses, make paddle safer, and can be at water inflow of the engine and avoid once more ignition trigger and badly damaged motor after flame-out.
To achieve these goals, the present invention has taked following technological scheme:
Said motor car engine water inlet protective equipment is made up of power supply, processor, depth of water display circuit, Resistance probe, green LED, buzzer, red light emitting diodes, relay A, relay B, trigger switch A, trigger switch B, circuit switch; Said Resistance probe connects said power supply, processor, green LED, the depth of water detection of buzzer formation and warning circuit through lead; Said processor connects said depth of water display circuit through lead and constitutes depth of water display system; Said trigger switch A links to each other with said power supply, red light emitting diodes and relay A through lead and constitutes the engine protection circuit; Said trigger switch B links to each other with motor start circuit, and said relay B links to each other with said processor.
Said Resistance probe is fixed on the automobile bottom, and its height is a little less than the height of automobile exhaust pipe mouth.
When said relay B switched on, said trigger switch A connected, said relay A energising, and said trigger switch B breaks off; When said relay B cut off the power supply, said trigger switch A broke off, said relay A outage, and said trigger switch B connects.
When said circuit switch breaks off, said relay A outage.
When automobile is paddled; If the depth of water does not reach Resistance probe with, probe place path then, green LED is luminous; Buzzer is sounded a buzzer simultaneously; The frequency of buzzer sounding raises with the rising of water level, and simultaneously depth of water display circuit is transferred to in-vehicle display system with depth of water dynamic changing data, shows the driver with form intuitively.When the depth of water reaches dangerous threshold state, trigger switch A is connected in relay B energising, and this moment, red light emitting diodes was luminous, and trigger switch B is broken off in relay A energising simultaneously, and this moment, motor start circuit opened circuit.Have only and to start automobile once more resetting again after the circuit switch disconnection.
Advantage of the present invention is: simple in structure, easy to use, and the variation of the depth of water in the time of can understanding automobile in real time and paddle, it is badly damaged also can to avoid motor car engine to start once more after flame-out because of intaking.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described further.
Accompanying drawing is the circuit diagram of motor car engine water inlet protective equipment of the present invention.
Among the figure: 1. power supply, 2. processor, 3. depth of water display circuit, 4. Resistance probe, 5. motor start circuit; 6. green LED, 7. buzzer, 8. red light emitting diodes, 9. relay A; 10. relay B, 11. trigger switch A, 12. trigger switch B, 13. circuit switchs
Embodiment
Below in conjunction with accompanying drawing the present invention is further described:
As shown in the figure, motor car engine water inlet protective equipment of the present invention mainly is made up of power supply 1, processor 2, external display circuit 3, Resistance probe 4, green LED 6, buzzer 7, red light emitting diodes 8, relay A9, relay B10, trigger switch A11, trigger switch B12, circuit switch 13.Resistance probe 4 constitutes the depth of water through wire connecting power 1, processor 2, green LED 6, buzzer 7 and detects and warning circuit; Processor 2 connects depth of water display circuit 3 through lead and constitutes depth of water display system; Trigger switch A11 links to each other with power supply 1, red light emitting diodes 8 and relay A9 through lead and constitutes the engine protection circuit; Trigger switch B12 links to each other with motor start circuit 5; The break-make of relay A9 control trigger switch B12, relay B10 links to each other with processor 2, the break-make of relay B10 control trigger switch A11.
During relay B10 energising, trigger switch A11 connects, relay A 9 energisings, and trigger switch B12 breaks off; During relay B10 outage, trigger switch A11 breaks off, relay A 9 outages, and trigger switch B12 connects.
When circuit switch 13 breaks off, relay A 9 outages.
When automobile was paddled, if the depth of water does not reach Resistance probe 4, then probe place path was connected the depth of water and is detected and warning circuit.This moment, green LED 6 was luminous, and buzzer 7 is sounded a buzzer simultaneously.Rising along with water level; The resistance that Resistance probe 4 inserts increases, and handles through processor 2, and the frequency of buzzer 7 sounding also raises with the rising of water level; Simultaneously depth of water display circuit 3 is transferred to in-vehicle display system with depth of water dynamic changing data, shows the driver with form intuitively.
When the depth of water reaches dangerous threshold state; Processor 2 control relay B10 energising makes the closed engine protection circuit of connecting of trigger switch A11; This moment, red light emitting diodes 8 was luminous; Relay A9 energising is simultaneously broken off trigger switch B12, and automotive ignition starting circuit 5 opens circuit at this moment, prevents to start once more after motor from stopping working because of intaking badly damaged.
If confirming to need ato unit once more under the situation that motor is not intake, reset again after can circuit switch 13 being broken off.
