In addition, the temperature sensor that the utility model relates to, without the need to arranging O-ring seal, this is because when the relevant physical parameter of measurement gas or liquid, needs the sealing realizing between sensor and object under test by O-ring seal, with Leakage prevention.Therefore, O-ring seal is one of parts very crucial in conventional sensors, and for the temperature sensor that the utility model relates to, and what measure due to it is the temperature of metal solid, there is not leakage problem, does not therefore also just need O-ring seal and worry to leak.
By the detailed description below with reference to accompanying drawing, other aspects of the present utility model and feature become obvious.But it should be known that this accompanying drawing is only the object design of explanation, instead of as the restriction of scope of the present utility model, this is because it should with reference to additional claim.Should also be appreciated that, accompanying drawing is only intended to structure described herein and flow process are described conceptually, unless otherwise noted, unnecessaryly draws accompanying drawing to scale.
Accompanying drawing explanation
Consult the detailed description of following embodiment by reference to the accompanying drawings, will understand the utility model more fully, reference numbers same in accompanying drawing refers to element same in view all the time.Wherein:
Fig. 1 is the structural representation of a kind of embodiment of the temperature sensor that the utility model relates to; And
Fig. 2 is the scheme of installation of the temperature sensor that relates to of the utility model and engine cylinder cover.
Embodiment
For helping those skilled in the art can understand the claimed theme of the utility model definitely, describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
See Fig. 1, it is the structural representation of the temperature sensor that the utility model relates to.As shown in the figure, this temperature sensor comprises end of probe 1, mounting flange 4, connecting portion 3 and connector 2.Described end of probe 1 is the measuring junction of perception determinand temperature, and this determinand is solid-state.In the present embodiment, end of probe 1 is made of metal, and this end of probe 1 is provided with the screw element of thread segment 11 for having surface, and it can be screwed in the mate with threaded holes engaged with it of solid determinand.Described mounting flange 4 is arranged on the place that end of probe 1 is connected with connecting portion 3.The outstanding structure of described mounting flange 4 provides the position for applying moment of torsion.That is, by mounting flange 4, end of probe 1 can link together more firmly with solid determinand, which ensure that measurement quality.In the present embodiment, mounting flange 4 is sexangle flange.But those skilled in the art will be appreciated that except sexangle flange, mounting flange 4 can also adopt other any be convenient to install flange shape or other forms of be convenient to moment of torsion apply parts.Described connecting portion 3 is the parts connecting end of probe 1 and connector 2, can be columniform shoulder.Connector 2 is made up of non-conducting material, preferably, can adopt plastic material.And connector 2 has the interface for receiving wire harness.Connector 2 and end of probe 1 are linked together by connecting portion 3.In the present embodiment, at connector 2 away from one end of end of probe 1 being also provided with the register pin 21 preventing wire harness from departing from.The temperature sensor related to when wire harness and the utility model is fixed and after connector 2 and register pin 21 work good, this register pin 21 plays locking effect.
The temperature sensor that the utility model relates to is specially adapted to the engine system of automobile.The temperature at the position such as cylinder body or cylinder cap of engine can be obtained by this temperature sensor, and can Real-Time Monitoring be carried out.As shown in Figure 2, the scheme of installation of the temperature sensor 100 related to for the utility model and engine cylinder cover 200.The cylinder cap 200 of engine processes preformed hole 300, to engage with the end of probe screw element of temperature sensor 100, after end of probe is screwed into, cylinder cap 200 is fixed by this preformed hole 300 and temperature sensor 100, therefore the temperature of temperature sensor 100 energy perception cylinder cap 200.Similarly, also can process preformed hole on the cylinder body of engine, to engage with the end of probe screw element of temperature sensor, after end of probe is screwed into, cylinder body is fixed by this preformed hole and temperature sensor, and therefore temperature sensor also can the temperature of perception cylinder body.The screw thread of end of probe can based on standard manufacture, and namely this screw thread can be M8 or M6 screw thread, or the screw thread of other specifications, and this depends on that the embody rule environment of engine is determined.At the other end of temperature sensor, what namely connector connected is engine wiring harness, end of probe can be connected with engine control module (ECM) by this connection.
The end of probe of temperature sensor of the present utility model is equivalent to a resistance unit, and its resistance value can change along with the difference of temperature.When after temperature sensor access engine cylinder cover or cylinder body, the resistant series namely provided with engine control module.When engine control module provides constant operating voltage, and the resistance that engine control module provides is constant, then the resistance value changed causes the output voltage on temperature sensor to change.Therefore, as long as engine control module obtains this output voltage values, just can obtain resistance value, corresponding temperature value can be obtained thus.Like this, corresponding relation is established between the electric signal obtained in temperature and the engine control module system of solid determinand.At temperature sensor duration of work, end of probe is fixed in the preformed hole on engine all the time, therefore achieves and monitors the real time temperature of engine.One skilled in the art will recognize that temperature sensor of the present utility model is not only applicable to the cylinder cap of engine or the temperature survey of these parts of cylinder body, the temperature survey of various solid components can also be applicable to.
The parts that this temperature sensor provides engine heat load high for engine control module are as the solid temperature at cylinder cap or cylinder body position, and this information will be used for carrying out overheating protection to engine by engine control module and control.
Above embodiment is only for illustration of the utility model; and be not limitation of the utility model; the those of ordinary skill of relevant technical field; when not departing from scope of the present utility model; can also make a variety of changes and modification; therefore all equivalent technical schemes also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
