Description

Engine lack of water warning device

Technical field

The utility model relates to a kind of engine lack of water warning device, relate in particular to a kind of circuit and the instrument front that need not change former car, make the car steering person can be in the way of driving according to the profit tutorial light show state on the instrument front, at any time grasp the water level in the water tank, the unfortunate event of avoiding engine to burn because of lack of water causes.

Background technique

General car engine is in order to keep normal operation, all need to offer the effect of engine lubricating by the machine oil in the sump, make the engine running can be more smooth and easy, yet engine is easy to generate high temperature in operation process, so must make an effective radiating treatment to the engine in the running usually, make engine temperature be unlikely to too high and cause burning, its heat radiation practice be utilize in the water tank water constantly circulation the engine in the running is provided the processing of radiating and cooling, the working life that so can guarantee engine.

Machine oil in the above-mentioned prior art sump all is provided with an engine oil caution lamp at fascia, show state by the engine oil caution lamp, the driver can learn whether machine oil has different shape and need check, yet the height of the water level in the water tank, have only the higher car type of minority the water tank tutorial light just to be housed in the motormeter panel, general car type then all is not equiped with the function of water tank tutorial light, in other words, when the driver of general car type wants to learn water level height in the water tank, all be directly to check the water yield in the water tank by opening bonnet, to judge whether supplementing water again, guarantee that engine is unlikely engine Yin Gaowen to be burnt because of water tank has water.

As from the foregoing, above-mentioned general car type is when whether monitoring water tank has water, must open the bonnet inspection, if in driving way then can't learn the water yield in the water tank immediately at all, very likely because of the water tank lacks water driver can't in time learn again, and the too high and accident of burning of engine Yin Wendu takes place.

In summary, described prior art on reality is used, obviously exists inconvenience and defective, so be necessary to be improved to the monitoring of cistern water level.

Summary of the invention

At above-mentioned defective, main purpose of the present utility model is to provide a kind of engine lack of water warning device, it need not change interior circuit and the instrument equipment of car originally, can install easily and use, and can learn immediately whether the water the present water tank has the not enough phenomenon of shortage from the show state of motormeter panel.

Embodiment

Hereinafter, will describe the utility model in detail.

The utility model provides a kind of engine lack of water warning device, and as shown in Figures 1 and 2, it is installed in automobile, and comprise the conducting plate 3 be located in the water tank 2, be located at the profit tutorial light 61 on the instrument front 6 and judge whether a control unit 5 of lack of water, wherein:

This conducting plate 3 is installed in the tank lid 21 on the water tank 2, and conducting plate 3 gos deep into the length of water tank 2 inside in order to determine the warning position of lack of water, can produce the Continuity signal of a circulating current when the height of water level of water tank 2 inside enough contacts with conducting plate 3; On the contrary, when the height of water level of water tank 2 inside is not enough to contact with conducting plate 3 because of there not being circulating current to produce a Continuity signal not, so be whether conducting or not conducting can judge the water level of water tank 2 inside near the warning position that should add water by the signal of conducting plate 3 outputs.

This control unit 5 is coupled to this conducting plate 3, as shown in Figure 3, control unit 5 is by microprocessor U1, resistance R 1, resistance R 2 and transistor Q1 form, control unit 5 is in order to receive the signal (water level probe monitoring circuit) that conducting plate 3 is exported, and be conducting or Continuity signal and drive the show state of the profit tutorial light 61 on this instrument front 6 by transistor Q1 not according to this signal, and circuit and instrument front in order not change former car, the machine oil lamp of instrument front 6 in the script car is used as profit tutorial light 61, profit tutorial light 61 is possessed simultaneously the dual state Presentation Function that shows the sump 4 inner machine oil situations and the water tank 2 inner water yields, be that conducting plate 3 is connected in profit tutorial light 61 by control unit 5, pressure switch 41 on the sump 4 then (is schemed slightly by the circuit that connects originally, in order to the monitoring machine fuel tank whether different shape is arranged) be connected in profit tutorial light 61, wherein control unit 5 does not need additionally to connect power supply again, and the circuit that is directly connected from pressure switch 41 is obtained electric power; Another kind of connection state, as shown in Figure 4, the output of water tank 2 and sump 4 is earlier through after the control unit 5, arrive the profit tutorial light 61 of instrument front 6 again, so when control unit 5 design, keep being used for the circuit of monitoring machine fuel tank 4 states originally, and set up a circuit in order to monitoring water tank 2 states in addition.

According to said structure, the water tank 2 that the sump 4 of engine 1 lubrication is provided and engine 1 heat radiation cooling action is provided, can be by the demonstration situation of profit tutorial light 61, need check to judge machine oil whether different shape is arranged or water tank 2 lack of water and need to add whether, the show state that makes the driver pass through profit tutorial light 61 can be grasped sump 4 and water tank 2 present up-to-date states at any time, needs traditionally to check the trouble and inconvenience of water tank 2 states by opening bonnet and save.

So, the automobile of said structure is housed, under normal circumstances open and profit tutorial light 61 light yellow always that do not start the engine 1 time when electric switch, and when engine 1 running, control unit 5 can be monitored earlier automatically, puts out entirely after making profit tutorial light 61 can put out glittering 6 times earlier again, and when profit tutorial light 61 when glittering continuously (as per minute 80 times), promptly represent lack of water, need notice immediately that water temperature changes, add water after the cooling of when temperature is too high, just need stopping; Though, but still need add water afterwards if temperature does not normally need to handle immediately.In addition, when profit tutorial light 61 light yellow always, represent that then sump 4 has problem.

Therefore, have following advantage by engine lack of water warning device of the present utility model:

(1) can check whether lack of water of water tank efficiently and effectively.

(2) install easily and need not change former car circuit and instrument equipment.

(3) installation cost is low and effect is good, and guarantees to avoid engine to burn because of overheated.

(4) whether automatic monitoring water tank of control unit energy and system be normal.

Be understandable that; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to the technical solution of the utility model and technical conceive, and all these changes and distortion all should belong to the protection domain of the utility model accompanying Claim.
