Embodiment
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.
The automobile rain sensor illumination threshold measurement mechanism 100 of the utility model embodiment is described referring to Fig. 1.
As shown in Figure 1, comprise according to the automobile rain sensor illumination threshold measurement mechanism 100 of the utility model embodiment: the illuminating part 20 that shading piece 10, intensity of illumination are adjustable, rain sensor 30, illumination photometry part 40, testing element 50.Wherein, enclosure space is limited in shading piece 10, rain sensor 30 can detect the intensity of illumination of illuminating part 20 and send signal of turning on light when intensity of illumination is in and turns on light illumination threshold, sends pass modulating signal when intensity of illumination is in and turns off the light illumination threshold, and testing element 50 is electrically connected with rain sensor 30 to receive that rain sensor 30 sends turns on light signal or close modulating signal and display receives and dispatches situation.Illumination photometry part 40, rain sensor 30, illuminating part 20 are positioned at enclosure space, and the distance between rain sensor 30 and illuminating part 20 equals the distance between illumination photometry part 40 and illuminating part 20.
According to the automobile rain sensor illumination threshold measurement mechanism 100 of the utility model first aspect embodiment, by in the enclosure space that rain sensor 30, illumination photometry part 40, illuminating part 20 is arranged on shading piece 10 to avoid the interference of extraneous light, utilize illuminating part 20 simulating nature light, by being arranged on illuminating part 20 equidistant position rain sensor 30 and illumination photometry part 40 with the brightness value making illumination photometry part 40 indirect detection go out rain sensor 30 place.During use, regulate the intensity of illumination of illuminating part 20, when the intensity of illumination received by rain sensor 30 be in rain sensor 30 turn on light illumination threshold time, rain sensor 30 sends to testing element 50 signal of turning on light; When the intensity of illumination received by rain sensor 30 be in rain sensor 30 turn off the light illumination threshold time, rain sensor 30 sends pass modulating signal to testing element 50.
Thus, above-mentioned automobile rain sensor illumination threshold measurement mechanism 100 can be utilized to carry out testing turn on light illumination threshold and illumination threshold of turning off the light with repeatedly accurate calibration rain sensor 30, be convenient to research and development and analyze.
In certain embodiments, automobile rain sensor illumination threshold measurement mechanism 100 also comprises: position adjustments part 60, and position adjustments part 60 is arranged for and regulates the distance between rain sensor 30 and illuminating part 20 and the distance between illumination photometry part 40 and illuminating part 20.That is, regulated by the distance of both position adjustments part 60 pairs of rain sensors 30 and illumination photometry part 40 and illuminating part 20 like this, the intensity of illumination scope making rain sensor 30 receive further increases, and strengthens the accuracy of the illumination threshold detected.
Further, position adjustments part 60 is arranged on outside shading piece 10.Like this, after measurement mechanism installation, when taking multiple measurements, just can regulate the distance of both rain sensor 30 and illumination photometry part 40 and illuminating part 20 without the need to opening shading piece 10, enhancing the convenience of measurement.
It will be understood by those skilled in the art that illumination photometry part 40, rain sensor 30, illuminating part 20 can regulate respectively by different position adjustments parts 60, also only can regulate the position of illumination photometry part 40 and rain sensor 30.
In a specific embodiment, position adjustments part 60 comprises synchronous drive mechanism, and synchronous drive mechanism has two Power output portions and two power delivery section are not connected with illumination photometry part 40 and rain sensor 30 to drive both to be synchronized with the movement.Thus, distance between illumination photometry part 40 and illuminating part 20, distance between rain sensor 30 and illuminating part 20 can adjusted in concert to any suitable location, not only convenient and swift, and enhance the consistance of adjustable range, further enhancing the accuracy of testing result.
But, the utility model is not limited to this, illumination photometry part 40 and rain sensor 30 can successively be regulated, that is position adjustments part 60 first regulate both among one and illuminating part 20 between distance, the distance between another and illuminating part 20 afterwards in both regulating.
