Following embodiment further specifies the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Below in conjunction with accompanying drawing the present invention being done one specifically introduces.
See also Fig. 1, be the exploded perspective view of sampling image lens shading cover structure of the present invention.Described sampling image lens shading cover structure 10, it comprises a camera lens module 12, a light compensating lamp 14, a light shield 16 and a capping 18.
Described camera lens module 12 comprise have a sampling image lens 122, one adjust pedestal 124 and a base 126.Described sampling image lens 122 is arranged on the described adjustment pedestal 124, and described adjustment pedestal 124 arranges on the described base 126.Described base 126 is in order to be fixed in metope or the end face of ceiling, described adjustment pedestal 124 can described base 126 do multiaxis to rotation running, make the described sampling image lens 122 can be with the adjustment of described adjustment pedestal 124, to enlarge the monitoring range of described sampling image lens 122 pick-up images.Described sampling image lens 122 is except capable of regulating capture monitoring range, and can when night or light are faint, carry out the acquisition of image, it is to provide enough illuminating raies by described light compensating lamp 14, make described sampling image lens 122 in the dim situation of environment, still can carry out the running of image capture.Described light compensating lamp 14 with the plural bracing frame 128 that has on the described adjustment pedestal 124 be set up in described sampling image lens 122 around, make described light compensating lamp 14 can cooperate the adjustment of described sampling image lens 122 monitoring ranges, necessary lighting demand is provided at any time.
Described light compensating lamp 14 comprises a circuit board 142 and at least one light-emitting component 144.Described light-emitting component 144 is set on the described circuit board 142, and mutually reaches electric connection.In the present embodiment, described circuit board 142 is an annular plate, and described light-emitting component 144 is plural light emitting diode (LED), makes described plural light emitting diode sequentially around on the annular plate that is arranged at described circuit board 142.The plural screw 1420 that the outer peripheral edges of described circuit board 142 annular plates have corresponding described plural bracing frame 128 arranges (as shown in Figure 2), support frame as described above 128 ends then have screw rod 1280 and arrange, the locking that mutually is spirally connected of the screw 1420 of described screw rod 1280 and described circuit board 142 is to set up described circuit board 142.The described adjustment pedestal 124 of described plural bracing frame 128 screw rods, 1280 distances has identical height, support frame as described above 128 is kept at grade with the described circuit board 142 that described screw rod 1280 supports locking, and make the annular plate of described circuit board 142 be sheathed on described sampling image lens 122 around.The inner peripheral of described circuit board 142 annular plates has relative hole 1422 and arranges, and described hole 1422 pins described light shield 16 by a fixed screw 146 and a spring 148.Described light shield 16 is a hollow and annular cylindrical shell, through pinning in the inner peripheral of described circuit board 142 annular plates, can be socketed the outer peripheral edges that are surrounded on described sampling image lens 122.Described light shield 16 annular barrel cooperate the fixed screw 146 of described hole 1422, have relative lug 162 in the both sides of described light shield 16 outer peripheral edges and arrange.The bottom surface of described lug 162 has a groove 1622, and described groove 1622 makes the described spring 148 that is sheathed on described fixed screw 146, can stably be arranged between described lug 162 and the described circuit board 142 (as shown in Figure 3).The end face of described lug 162 has a screw 1624, the locking that is spirally connected of described screw 1624 and described fixed screw 146, to make described spring 148 have by compression the elastic force of answer, the back stretch of described spring 148 makes this light shield 16 have lasting elasticity upwards.When the described base 126 of described capping 18 and described camera lens module 12 is spirally connected fixedly, the transparent ball-type cover body 182 that described capping 18 tops have with the described sampling image lens 122 of capping and on every side around described light compensating lamp 14.The apical margin 164 of described light shield 16 its annular barrel between described sampling image lens 122 and the described light compensating lamp 14 is higher than described sampling image lens 122.Described light shield 16 is because being subjected to described spring 148 to continue elasticity upwards, with the inner edge surface of the apical margin 164 that makes described light shield 16 annular barrel and described ball-type cover body 182 mutually against connecting airtight.
Please consult again Fig. 4, the apical margin 164 of described light shield 16 and the inner edge surface of described ball-type cover body 182 are mutually against connecting airtight, wherein said apical margin 164 materials are the rubber mass material, the suitable elasticity that has by described light shield 16, can make described apical margin 164 and described ball-type cover body 182 inner edge surfaces against maintaining closely state, can make described light compensating lamp 14 parts fail to pass the light of described ball-type cover body 182, can't reflect and enter in the scope that described light shield 16 centers on, and the suitable elasticity that has of described light shield 16, make described apical margin 164 and described ball-type cover body 182 inner edge surfaces against the distortion that can avoid described apical margin 164 rubber mass materials, keep the complete of described apical margin 164 annular barrel.The scope that described light shield 16 annular barrel center on is the effective range of described sampling image lens 122 pick-up images, make described sampling image lens 122 when using described light compensating lamp 14 to carry out image capture, can avoid completely effectively the impact of parasitic light, keep good image output quality.
Sampling image lens shading cover structure of the present invention, between described sampling image lens and described light compensating lamp, has the described light shield with the elasticity winding, the apical margin of described light shield can be closely against the inner edge surface of the transparent ball-type cover body in described capping top, can intercept the parasitic light that described light compensating lamp forms in described capping fully enters in the effective range of described sampling image lens pick-up image, keep ambient light good image output quality when not enough, it is simple in structure, assembling can reduce manufacturing cost and have better effective utilization easily.
In addition, those skilled in the art also can do other variation in spirit of the present invention, and certainly, the variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
