Fig. 2 is the operation principle sketch map of distance sensing device shown in Figure 1.
Embodiment
See also Fig. 1, Fig. 1 is the structural representation of the distance sensing device of one embodiment of the invention.
In the present embodiment, distance sensing device includes but not limited to transport module 10, lens module 11, light emission module 12, photoinduction module 13, circuit board 14 and shell 15.
Transport module 10 comprises the first passage 101 and second channel 102 that is provided with at interval and is parallel to each other.Need to prove: transport module 10 can adopt materials such as rubber or silica gel material one-body molded and make, and first passage 101 and second channel 102 are for running through the through hole that transport module 10 is provided with.In addition, for the laser propagation effect that guarantees light and/or guarantee to obtain enough light, more passages can be set, not limit at this.
Lens module 11 can adopt materials such as plastic cement to make; And lens module 11 is set to only see through the light with preset frequency, and particularly, preset frequency can be the infrared light of 1012Hz ~ 5 * 1014Hz; Certainly filter out under the prerequisite of disturbance in assurance; Preset frequency also can fluctuate in certain number range, for example can be set to 950Hz ~ 1200Hz etc., does not limit at this.One end of first passage 101 and an end of second channel 102 are fixedly set in respectively on the lens module 11 same surfaces; And, therefore adopt the less lens of area to process two processes that lens module 11 can realize launching light and reflection ray because transport module 10 adopts binary channels that the mode of (i.e. sealing each other) is set at interval; Furthermore; Because the area of lens module 11 is less; Therefore distance sensing device can be arranged on the optional position at terminal very neatly as required, has increased design freedom, has also solved the bigger lens of available technology adopting area and the problem of inconvenience setting.
Light emission module 12 can be light emitters such as LED, and it is placed in the other end of first passage 101, and it can send the emission light with preset frequency, and emission light is then through first passage 101 and pass transport module 10.As previously mentioned, light emission module 12 generally sends the infrared light that preset frequency is 1012Hz ~ 5 * 1014Hz, certainly, also can send the emission light of other frequencies, does not limit at this.
Photoinduction module 13 can be for light sensor etc., and it is placed in the other end of second channel 102, and induction is stopped the reflection ray that is produced through second channel 102 because of emission light by exterior object.Need to prove; Photoinduction module 13 also has the function that realizes distance calculation; When the emission light that sends when light emission module 12 is reflected to photoinduction module 13; Photoinduction module 13 can calculate distance according to time etc., in the scope that present technique field personnel understand, does not give unnecessary details.Be not difficult to find out that from Fig. 1 light emission module 12 carries out the interval with the binary channels set-up mode that photoinduction module 13 is transmitted module 10, and can reduce the disturbing property mutually between the light.In addition, the position between light emission module 12 and the photoinduction module 13 can exchange, and in the scope that present technique field personnel understand, does not give unnecessary details.
Circuit board 14 can also can be rigid printed circuit board for flexible printed circuit board, does not limit at this.Wherein, the other end of the first passage 101 of transport module 10 and the other end of second channel 102 are fixedly set in respectively on the circuit board 14 same surfaces, and light emission module 12 is electrically connected with circuit board 14 respectively with photoinduction module 13.
Shell 15 is for being provided with the terminal of present embodiment distance sensing device such as the housing of mobile phone or computer etc., its can with lens module 11 nested settings, such as lens module 11 embeds and is arranged in the shell 15, do not limit at this.
Please further consult Fig. 2, Fig. 2 is the operation principle sketch map of distance sensing device shown in Figure 1, supposes to have an exterior object 20 to be positioned near the lens module 11, and at this moment, the course of work of distance sensing device embodiment of the present invention is:
The emission light with preset frequency that light emission module 12 sends is through first passage 101 and pass lens module 11;
13 inductions of photoinduction module are stopped the reflection ray that produced because of launching light by exterior object 20 through second channel 102;
Then, photoinduction module 13 is calculated lens modules 11 to the distance between the exterior object 20, when exterior object 20 apart from shell 15 less than a preset distance after, photoinduction module 13 acknowledge(ment) signals activate corresponding software set function.
The present invention also provides a kind of mobile phone, comprises touch-screen (figure does not show), distance sensing device of the present invention, and wherein, lens module 11 embeds and is arranged in the shell 15.Difference from prior art is, the mode of scioptics module 11 can be avoided realizing the function that distance perspective is answered through touch screen zone, thereby can distance sensing device be arranged on the optional position of mobile phone according to actual needs and neatly.In addition,, can activate and/or close the corresponding software set function of mobile phone etc., in the scope that present technique field personnel understand easily, not give unnecessary details calculating lens module 11 after the distance between the exterior object 20.
Mobile phone of the present invention and distance sensing device embodiment thereof are through being provided with lens module and transport module separately; Needn't relend and help the function that touch-screen realizes that distance perspective is answered; Make distance sensing device to be arranged on neatly on the optional position at terminals such as mobile phone; And can utilize the design space fully, thus the diversity of product design increased, and reduced cost.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
