Embodiment
Please refer to Fig. 3 and Fig. 4, high and implement complicated problem for the prior art manufacturing cost, the present invention proposes a kind of video camera 3 with sky shade.The infrared tubular video camera of take is example, and this video camera 3 comprises: integrated preposition parts 31 and stack shell 32.Wherein these integrated preposition parts 31 comprise brim part 311, connecting portion 312, front cap 313, cage ring 314 and some installing holes 315.
The camera lens sighted direction of take is the place ahead, and the interior profile at the rear outline of described integrated preposition parts 31 and described stack shell 32 front opening places is mutually adaptive, mutually docks with stack shell 32 to allow integrated preposition parts 31.In installation process, integrated preposition parts 31 are with after stack shell 32 is aimed at, and some (in present embodiment the being 3) installing hole 315 that forms of in the past extending internally out on cap 313 will be aimed at the abutting joint hole 321 formed that extends internally on stack shell.With after abutting joint hole 321 is aimed at, the operator can be screwed in installing hole 315 and abutting joint hole 321 screw or other fixtures so that integrated preposition parts 31 and stack shell 32 are fixed together at installing hole 315.
Because connecting portion 312 extends towards front cap 313 inside, make front cap inner hollow partly be rendered as U-shaped, in a preferred embodiment, the position of this U-shaped hollow space is corresponding with the position of built-in light compensating lamp (such as built-in infrared light compensating lamp), can allow the camera lens side the light of one or more built-in light compensating lamp (not shown) pass through.Certainly the shape of this opening may not be U-shaped, can be also other shapes, but this opening part relative with built-in light compensating lamp must be open or transparent, on area, will meet the designing requirement of light filling.
In the present invention, the parts that described integrated preposition parts 31 are one of the forming, its material are chosen as the material of weak reflective color usually, such as the black material.So-called weak reflective color material refers to that those can be to light compensating lamp light reflection weak strength to the color that meets developer's design objective, for different video cameras, the standard difference of this weak reflective color material, but for a specific video camera, its standard is normally certain.Please refer to Fig. 4, a kind of preferred embodiment in, stack shell 32 can comprise external brim part 322 equally, and brim part 311 is positioned at the below of external brim part 322, the upper end of its past cap 313 is towards away from lens direction, extending, between built-in light compensating lamp and external brim part 322, with the light of avoiding built-in light compensating lamp, arrive the inner surface of external brim part 322.
Because adopting weak reflective material, make integrated preposition parts 31, therefore the reflecting power of brim part 311 is normally very weak, the light major part that built-in light compensating lamp sends all can't be absorbed and can't reflect by brim part, has avoided the impact of reverberation on image effect.So no matter which type of color is stack shell 32 appearances spray does not have any negative effect that brings the built-in light compensating lamp light of reflection yet, because brim part 311 has sheltered from the light of built-in light compensating lamp.Now, external brim part 322 does not need the secondary color spray to carry out its inner surface of blacking, has therefore reduced enforcement complexity and the manufacturing cost of stack shell 32.And external brim part 322 from the outside contraposition in the inner the brim part 311 of section formed and blocked, so can not affect again the colour planning of the outward appearance part of product.
Please refer to Fig. 5, in actual product, except integrated preposition parts 31, the video camera front portion also comprises transparent glass sheet 33, outer ring translucent cover 34 and water proof ring 35.Wherein transparent glass sheet 33 can be arranged on cage ring 314 inside, and outer ring translucent cover 34 is between integrated preposition parts 31 and water proof ring 35, and from the camera lens view direction, integrated preposition parts 31 are positioned at the place ahead of outer ring translucent cover 34.In the process of assembling, after above-mentioned parts is ready to, according to positional alignment and will aforementioned three pairs of installing holes 315 with after abutting joint hole 321 is aimed at, by three screws, install and fix.According to the scene of the concrete application of video camera, this outer ring translucent cover 34 selects different filter discs to adapt to the shooting needs of video camera.This filter disc can be IR-cut filter disc, white glass etc.
Please refer to Fig. 6, it is the detailed construction exploded view of Fig. 2 scheme.The project organization of prior art is decomposed to contrast can be found: in the prior art, cage ring, protecgulum are all individual part; Each individual part means the mould that will offer a correspondence, and the cost of die sinking is high often.In the present invention, for traditional secondary color spray mode, the technical problem of not only avoiding secondary color spray isolation to cause, and due to cage ring and protecgulum all together integrated, reduced again by a die sinking.In addition, in terms of existing technologies, the present invention has not only reduced the manufacturing cost of part, due to more parts by after integrated, again decrease the complexity of manual assembly, the whole implementation cost has further obtained again reduction.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of making, be equal to replacement, improvement etc., within all should being included in the scope of protection of the invention.
