Description
Technical field
The utility model relates to car engine cooling system, more particularly, relates to a kind of Motronic control maps thermostat.
Background technique
Thermostat is the vitals of motor car engine, and its function is the temperature of regulating the engine cycles cooling water, is in best state work to guarantee motor.At present, electronic thermostat is to install a resistance heater on the core temperature control element of common waxtype thermostat additional, the temperature of paraffin is subjected to the acting in conjunction of resistance heating amount and coolant temperature like this, and resistance heater can be controlled the voltage and current value by ECU and regulates and add heat.Therefore, ECU can be according to different operating mode needs, and that constantly regulates thermostat just opens the temperature that temperature and standard-sized sheet temperature are controlled cooling liquid.At that time, the heating element of present electronic thermostat be not easy to select suitable heating element, and the sealing of thermostat is also to be the processing difficulties of electronic thermostat at present.
The model utility content
A kind of electronic thermostat of the utility model, its objective is provides a kind of simple in structure, and sealability is more reliable, and is active in one's movements, and controls accurate thermostat.
A kind of electronic thermostat of the utility model comprises: push rod, and the thermostat shell is provided with spring in the thermostat shell of described hollow structure, and push rod withstands on the spring, and can the unrestricted motion with the compression of spring, and spring is connected with lead-in wire.
Described spring is arranged on the thermostat housing bottom, and spring is the memory metal material.
At described push rod outer installment sebific duct, be in sealing state thereby make between push rod and the thermostat shell.
Described lead-in wire is connected with spring, and is drawn out to the thermostat housing exterior.
The position of drawing the thermostat shell at described lead-in wire is provided with sealer, is in sealing state thereby make between lead-in wire and the thermostat shell.
The sebific duct of described electronic thermostat compresses by the gland of installing in the thermostat upper cavity, and is sleeved on the push rod outer ring by one, and the seal ring that is between gland and the sebific duct guarantees the sealing of push rod in the process of moving up and down.
The technical solution of the utility model directly impels the memory metal camber of spring to get a desired effect for the two ends making alive generation heat of memory metal spring by ECU.The utility model is simple in structure than the conditional electronic thermostat, and is active in one's movements, and control is accurate, the reliability height, and adaptability is strong.
Description of drawings
Below expressed content of each width of cloth accompanying drawing in this specification and the mark among the figure are made brief description:
Fig. 1 is the sectional structure schematic representation of a kind of electronic thermostat of the utility model;
Be labeled as among the figure: 1, push rod; 2, thermostat shell; 3, sebific duct; 4, lead-in wire; 5, gland; 6, small sealing ring; 7, spring; 8, sealer; 9, thermostat housing bottom; 10, thermostat upper cavity.
Embodiment
Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and working principle etc. are described in further detail embodiment.
As shown in Figure 1, a kind of electronic thermostat comprises: push rod 1, and thermostat shell 2 is provided with spring 7 in the thermostat shell 2 of described hollow structure, and push rod 1 withstands on the spring 7, and can the unrestricted motion with the compression of spring, and spring 7 is connected with lead-in wire 4.
Described spring 7 is arranged on thermostat housing bottom 9, and spring 7 is the memory metal material.
At described push rod 1 outer installment sebific duct 3, be in sealing state thereby make between push rod 1 and the thermostat shell 2.
Described lead-in wire 4 is connected with spring 7, and is drawn out to thermostat shell 2 outsides.
The position of drawing thermostat shell 2 at described lead-in wire 4 is provided with sealer 8, is in sealing state thereby make between lead-in wire 4 and the thermostat shell 2.
The sebific duct 3 of described electronic thermostat compresses by the gland of installing in the thermostat upper cavity 10 5, and is sleeved on push rod 1 outer ring by one, and the seal ring 6 that is between gland 5 and the sebific duct 3 guarantees the sealing of push rod 1 in the process of moving up and down.
The present invention makes temperature sensing spring 7 to memory metal, directly controls the flexible of this temperature sensing spring 7 by ECU control voltage and current value, opens the purpose of closing thereby reach control thermoregulator valve.
By the 4 spring 7 two ends making alives to the memory metal material that go between, because memory metal itself also is a thermal resistor, body temperature raises behind making alive, causes distortion.The distortion that is caused by spring 7 moves up by sebific duct 3 promotion push rods 1, thereby closes the opening and closing of controlling the motor major cycle as common thermoregulator by opening of control thermoregulator valve.Because there is sealing problem in the course of the work in this part, so the lead portion of lower end adopts sealer 8 sealings, and the employing gland 5 of upper end compresses sebific duct 3, guarantees the sealing of push rod 11 in the process of moving up and down by a seal ring 6 therebetween.
Lead-in wire 4 of the present utility model connects spring 7, by going between 4 to spring 7 two ends making alives, impel spring 7 to heat up, surpass the temperature of setting at marmem after, refresh memory, spring 7 is stretched out, push rod 1 is backed down, make thermostat be in open mode, make cooling liquid enter radiator and cool off, guarantee that motor keeps normal working state.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
