[embodiment]
Figure 1A illustrates the structural representation of automatic sun-shading mechanism when sunshading board is not opened of first embodiment of the invention, and Figure 1B illustrates the structural representation of automatic sun-shading mechanism when sunshading board is opened of Figure 1A.Please refer to Figure 1A, the automatic sun-shading mechanism 140 of present embodiment is applicable to a Vehicular navigation device 100, and is installed on this Vehicular navigation device 100.Vehicular navigation device 100 for example is one to have the personal digital assistant of satellite positioning functions, and it comprises a first surface 110, a second surface 120, a screen 130 and an automatic sun-shading mechanism 140.Wherein, screen 130 is disposed on the second surface 120.Automatic sun-shading mechanism 140 comprises a sunshading board 142, a driver 144, an optical sensor 146 and a voltage-operated device 148.
Sunshading board 142 is disposed on the first surface 110 of Vehicular navigation device 100, and purposes is the light that covers from screen 130 top incidents, and the material of this sunshading board 142 for example is light tight material.Driver 144 is disposed among the Vehicular navigation device 100, and can drive sunshading board 142 and skidded off by first surface 110, and this driver 144 for example is a step motor.Optical sensor 146 is disposed on the first surface 110 of Vehicular navigation device 100.In addition, voltage-operated device 148 is connected between driver 144 and the optical sensor 146, is used to control the open and close of sunshading board 142.
Fig. 2 illustrates the operation workflow figure of an automatic sun-shading mechanism.Please refer to Fig. 2, when sunray shines on first surface 110, the amount of incident that optical sensor 146 can the detecting light, the voltage signal that sends a correspondence then is to voltage-operated device 148.After voltage-operated device 148 receives this corresponding voltage signal, can export a control voltage to driver 144.Driver 144 receive just can mobile sunshading board 142 behind the control voltage the position so that sunshading board 142 opens or cuts out.If the light amount of incident that optical sensor 146 is detected surpasses default value, the voltage signal that then can send a correspondence is to voltage-operated device 148, voltage-operated device 148 transmits corresponding control voltage again to driver 144, so that sunshading board 142 is opened (shown in Figure 1B), just so sunshading board 142 can cover the light of incident above screen.In addition, if light intensity deepening and light amount of incident are less than or equal to default value, then optical sensor 146 sends another corresponding voltage signal, can make driver 144 close sunshading board 142 (shown in Figure 1A) at last.
What deserves to be mentioned is that if optical sensor 146 is a photoresistance, then when sunray shone in photoresistance, the resistance value of photoresistance can diminish.Because the cause of circuit design, this will cause the magnitude of voltage of the voltage signal that optical sensor 146 exported to become big.When the light amount of incident that is detected when optical sensor 146 is bigger than a certain default value (when also the resistance value of photoresistance is less than a certain corresponding resistance value), the magnitude of voltage of the voltage signal that voltage-operated device 148 receives also can be bigger than a corresponding magnitude of voltage.At this moment, pressure control device 148 just can be sent one and control voltage to driver 144 to open sunshading board 142.On the contrary, when if the light amount of incident that is detected when optical sensor 146 is less than or equal to a certain default value (when also the resistance value of photoresistance is greater than a certain corresponding resistance value), the magnitude of voltage of the voltage signal that voltage-operated device 148 receives also can be less than a corresponding magnitude of voltage.At this moment, pressure control device 148 just can be sent one and control voltage to driver 144 to close sunshading board 142.
Fig. 3 illustrates the stereo amplification figure in the zone that is denoted as A in Fig. 1.Please refer to Fig. 3, in the present embodiment, the bottom of sunshading board 110 has a slide block 142a, and it is activated the control of device 144, and the first surface 110 of Vehicular navigation device 100 then has a slideway 110a accordingly.The mode of driver 144 control slide block 142a for example is to link with belt to drive or drive with tie rod.Control when slide block 142a is subjected to driver 144, when the end of slideway 110a moved to the other end, the some of sunshading board 142 can move on to the top of second surface 120 from first surface 110.As above-mentioned, when incident light quantity surpassed default value, sunshading board 1 42 skidded off (shown in Figure 1B) through above-mentioned mode by first surface 110; When incident light quantity is reduced to default value or default value when following, sunshading board 142 can with opposite mode back slide first surface 110 on (shown in Figure 1A).
Merit attention and be, though the automatic sun-shading mechanism of present embodiment is to be installed on the Vehicular navigation device, automatic sun-shading mechanism of the present invention also can be made an independent agency that is applicable to the Vehicular navigation device according to different demands.
Fig. 4 A illustrates the structural representation of automatic sun-shading mechanism when sunshading board is not opened according to second embodiment of the invention, and Fig. 4 B illustrates the structural representation of automatic sun-shading mechanism when sunshading board is opened of Fig. 4 A.Please refer to Fig. 4 A, the automatic sun-shading mechanism 240 of present embodiment is applicable to a Vehicular navigation device 200, and is installed on this Vehicular navigation device 200, and is similar to the automatic sun-shading mechanism 140 of first embodiment.Automatic sun-shading mechanism 240 and automatic sun-shading mechanism 140 are different be in: the sunshading board 242 of automatic sun-shading mechanism 240 is disposed on the second surface 220, and the bottom of sunshading board 242 has a rotating shaft 242a.The light amount of incident that is detected when optical sensor 246 surpasses default value, the voltage signal that then can send a correspondence is to voltage-operated device 248, voltage-operated device 248 transmits corresponding control voltage to driver 244 again and rotates to drive rotating shaft 242a, sunshading board 242 make sunshading board 242 start (shown in Fig. 4 B), just so can cover the light of incident above screen from second surface.In addition, if the light intensity deepening, then optical sensor 246 sends another corresponding voltage signal, can make driver 244 drive rotating shaft 242a at last and rotate to close sunshading board 242 (shown in Fig. 4 A).
In addition, identical with first embodiment, though the automatic sun-shading mechanism of present embodiment is to be installed on the Vehicular navigation device, automatic sun-shading mechanism of the present invention also can be made an independent agency that is applicable to the Vehicular navigation device according to different demands.
In sum, automatic sun-shading mechanism of the present invention has following advantages at least:
