Following embodiment will combine above-mentioned accompanying drawing to further specify the present invention.
Embodiment
To combine accompanying drawing that the present invention is done one below specifically introduces.
See also shown in Figure 1ly, a kind of sampling image lens dedusting structure 10 provided by the invention comprises a camera lens module 12, an optical filter framework 14 and a protecgulum 16.
Said camera lens module 12 has a camera lens 122, an image sensor 124 and a circuit substrate 126.Said image sensor 124 is arranged on the said circuit substrate 126 and with said circuit substrate 126 and electrically connects.Said camera lens 122 is arranged on the said protecgulum 16, and said protecgulum 16 front ends have a cover plate 162, and the rear end has an accommodation space 164.Have a screw 166 that communicates with said accommodation space 164 on the said cover plate 162, said screw 166 is in order to the said camera lens 122 that is spirally connected.Said accommodation space 164 is in order to holding and fixing said image sensor 124 and said circuit substrate 126, and makes the optical axis of the said camera lens 122 that said screw 166 is spirally connected can be corresponding and aim at said image sensor 124.Said image sensor 124 is in order to 122 picked image of the said camera lens of sensing, and through said circuit substrate 126 institute's picked image transferred out.
Said optical filter framework 14 is arranged in the said accommodation space 164 of said protecgulum 16, and is positioned at the top of said image sensor 124.Said optical filter framework 14 has at least one framework 142 and a fixed frame 20.In this embodiment, said optical filter framework 14 has two framework 142a, 142b, in order to two optical filter 18a, 18b (as shown in Figure 2) to be set respectively.Said optical filter 18a, 18b can correspond respectively to said image sensor 124, make the light of said camera lens 122 see through said optical filter 18a, 18b aims at said image sensor 124.Said optical filter 18a, 18b filter the unnecessary light through said camera lens 122 in response to ambient light, use so that the said image sensor 124 ability sharp images that sensing captured.Wherein said optical filter 18a is fixed on the said framework 142a with the gummed mode, and said optical filter 18b then is locked on said another framework 142b through said fixed frame 20.The configuration of said fixed frame 20 and said framework 142b are complementary, and said fixed frame 20 can be involutory with said framework 142b.Said fixed frame 20 is plates, and said fixed frame 20 peripheries have gulde edge 202 and a fixed edge 204 relative with said gulde edge 202.Said gulde edge 202 has at least one spacer 206, and said spacer 206 is orthogonal shape (as shown in Figure 3) with the plates of said fixed frame 20.Has a pilot hole 2062 on the said spacer 206; Has a projection 144 on the side of the corresponding said pilot hole 2062 of said framework 142b; Said projection 144 interspersed being buckled in the pilot hole 2062 on the said spacer 206 are fixed on said fixed frame 20 1 ends on the said framework 142b.Said fixed edge 204 has at least one fixed orifice 208; Has a fixing threaded hole 146 on the side of the corresponding said fixed orifice 208 of said framework 142b; A fixed screw 22 passes said fixed orifice 208 and screws togather locking with said fixing threaded hole 146; The other end of said fixed frame 20 is fixed on the said framework 142b, is arranged at the said optical filter 18b in the said framework 142b with firm clamping.
See also Fig. 2, said fixed frame 20 is locked in position on the said framework 142b corresponding to the said screw 166 of said protecgulum 16.The pore diameter range of said screw 166 is greater than the framework 142b of said optical filter framework 14, thereby sees through the running that said screw 166 can be dismantled or assemble said fixed frame 20.Said sampling image lens dedusting structure 10; When finished product or assembling test; If find that having grit on said image sensor 124 surfaces must remove, can earlier said camera lens 122 be unloaded in the said screw 166 that is spirally connected, remove said fixed screw 22 through said screw 166 again; Remove the snapping of pilot hole 2062 and said projection 144 on the said spacer 206 then, so just can said fixed frame 20 be taken out (as shown in Figure 4) in said screw 166.After said fixed frame 20 took out, the said optical filter 18b that just can easily said fixed frame 20 be locked took out in said screw 166.After said optical filter 18b takes out, said screw 166 directly corresponding said image sensor 124, thereby can clean dedusting with the cleaning cotton fibre to said image sensor 124 through said screw 166.Compared to the structure that need said image sensor 124 be disassembled in said protecgulum 16 at present, sampling image lens dedusting structure 10 according to the invention is obviously convenient to be used and respond well.After said image sensor 124 cleanings were accomplished, the locking that can see through 166 couples of said optical filter 18b of said screw and said fixed frame 20 was equally assembled, and makes said end user also can carry out the dedusting operation of rear end voluntarily.
Sampling image lens dedusting structure of the present invention has the structure that can in said screw 166, dismantle and assemble said optical filter 18b; Help the dedusting running of said camera lens module 12; It is simple in structure, and assembling can reduce manufacturing cost and have preferable effective utilization easily.
In addition, those skilled in the art also can do other variation in spirit of the present invention, and certainly, these all should be included within the present invention's scope required for protection according to the variation that the present invention's spirit is done.
