Embodiment
As shown in Figure 1, in the present embodiment, video camera comprises: camera lens mounting base 1, rear burnt adjusting device 2, transducer mounting base 3, transducer 4, and circuit board, data output interface etc.In the present embodiment, eliminate the parts irrelevant with inventive point of the present utility model, only depict transducer, sensor base, rear burnt adjusting device, camera lens mounting base (being commonly called as front face) in FIG.Camera lens mounting base can be provided with camera lens.But, improvements of the present utility model and camera lens have nothing to do.
As Figure 1-4, in the present embodiment, sensor base 3 adopts PCB fixed head, and transducer 4 is welded on pcb board on the surface, and welding position precision and the depth of parallelism are ensured by welding procedure.Pcb board self evenness is ensured by mask-making technology, and camera lens mounting base 1 and PCB fixed head 3 are fixed to one another by four screws, and arrange certain thickness rear burnt adjusting device 2 between.And then, spacing can be adjusted by rear burnt adjusting device 2 between PCB fixed head 3 and camera lens mounting base 1.
As shown in Figure 3 and 4, the C type that the structure of rear burnt adjusting device 2 is substantially rectangular, is made up of two side arms, 21,22 and linking arm 23.As shown in the figure, the outside of the upper end of side arm 21 forms the installing hole 24 of a semicircle or counterfort shape, and corresponding sidewall 21 internally bends at an upper portion thereof.The lower end of similar side arm 21, also has a similar installing hole 25.Installing hole 24 and 25 is all towards the outside of burnt adjusting device after C type.Structure and the sidewall 21 of side arm 22 are similar, and just with its specular, it also forms two installing holes 26,27 in outside.Four screw one_to_one corresponding of four installing holes of rear burnt adjusting device 2 and the camera lens mounting base 1 of video camera and PCB fixed head 3.The rear burnt adjusting device installation and removal of this special construction are all extremely convenient.
In use, for with a camera lens mounting base, the parameter of all the sensors of this pedestal is used to gather by preparing, theory calculate and actual measurement checking is carried out by designer, determine the size of rear burnt adjusting device corresponding to every a transducer, during batch production, producers carry out the coupling of transducer and rear burnt adjusting device according to correspondence table.The rear burnt adjusting device transducer that correspondence is different respectively of different-thickness specification, the thickness error of rear burnt adjusting device and evenness depend on materials and the Sheet Metal Forming Technology of copper sheet sheet material.
When needs by camera application of the present utility model in an application-specific scene time, the parameter of the transducer required for this application, can determine the thickness of the rear burnt adjusting device corresponding to this transducer.Then, this transducer being arranged on pcb board, and picking out corresponding rear burnt adjusting device, being arranged between pcb board and camera lens mounting base, for mating corresponding transducer.After installing, this video camera does not need to debug further, mates between transducer with camera lens.
In sum, the utility model reaches rear Jiao's adjustment object by the rear burnt adjusting device of simple different size, makes same camera lens mounting base can carry many moneys transducer, and can ensure the depth of parallelism that transducer is installed.When needing the imaging carrying out different scene, the thickness of the rear burnt adjusting device making transducer blur-free imaging is determined by theory calculate and actual commissioning, the machining accuracy of metallic gasket is ensured by technique, thus all adopt the rear burnt adjusting device of same size when producing in batches, burnt debugging step after exempting.
Rear burnt adjusting device of the present utility model and corresponding video camera can realize the compatible many moneys focal plane of same camera lens mounting base not at the transducer of same position, and can ensure that parallelism precision installed by transducer, it is firm to install, and debugging is convenient, and resistance to shock is good.
It should be noted that; the shape of all parts in accompanying drawing of the present utility model is all schematic; there is some difference not get rid of itself and its true shape; accompanying drawing is only for being described principle of the present utility model, and the detail of parts shown in figure is not the restriction to utility model protection scope.Those skilled in the art also should be appreciated that, above-described embodiment is also only the explanation to exemplary implementation of the present utility model, not the utility model are comprised to the restriction of scope.
