With reference to the accompanying drawing of specification, by being further described to the embodiment of the present invention, make this hair
Bright technical scheme and its advantage is clearer, clear and definite.It is exemplary, purport to describe embodiment below with reference to accompanying drawing
The present invention is being explained, and is being not considered as limiting the invention.
Preferred embodiment provided by the invention：As shown in Fig. 1 ~ Fig. 5, a kind of prism structure of full shot, it includes mirror
Cylinder 10, the prism 20 being installed in lens barrel 10 and positioning eyeglass 30；
The lens barrel 10 is provided with recess 11, and the size of recess 11 is corresponding with positioning eyeglass 30, so that positioning 30 compact peace of eyeglass
It is placed in the recess 11；
Positioning eyeglass 30 is provided with binding face 31, and prism 20 is affixed directly to position the binding face 31 of eyeglass 30 using adhesive, with
It is overall to realize that positioning eyeglass is formed with prism arrangement；It is put into by the way that integral positioning eyeglass will be pasted with prism in lens barrel 10,
And the positioning pairing of eyeglass 30 is positioned over the recess 11, reduces the process complexity of the processing of lens barrel 10.
The prism 20 is split-type structural, and it includes the first prism 21 and the second prism 22, positions the quantity of eyeglass 30
It is corresponding with the number of prisms of split.
First prism 21 has two 45 degree of interior angle, and the mismachining tolerance at 45 degree of angles of the first prism is in positive and negative 30 seconds scopes
It is interior.
First prism 21 is directly fitted in using adhesive on positioning eyeglass 30；Second prism 22 is fitted in another positioning
Eyeglass 30, will be fitted with the first prism respectively, the positioning eyeglass of the second prism is positioned in lens barrel 10, make the first prism 21 and
Two prisms 22 are combined into wide-angle lens in lens barrel 10.
The angle of visual field of wide-angle lens is more than 180 degree, and equipped with imaging sensor, imaging sensor is used to absorb wide-angle lens
The image that wide-angle lens is formed；The present invention forms wide-angle lens by the way that prism cementing is placed in lens barrel on eyeglass, reaches
Simplify lens barrel structure, reduce the difficulty of processing of lens barrel, while by the way that prism cementing on eyeglass, can more be reduced to adding for prism
Work, production efficiency is improved, reduce production cost.
Prism positions major defect in existing full shot：1. if prism were integral, the processing request of that prism
It is very high（The position relationship entered between smooth surface, exiting surface, reflecting surface of prism）It is and also high to the positioning requirements of prism in lens barrel
Cause lens barrel machining accuracy high, processing difficulties；2. if prism is split type, the contrast locating in lens barrel of that prism is integral
Formula it is more difficult, add the position relationship requirement between prism；Such as Fig. 1, to ensure in the processing of prism 2 45 ° ±
30 ", such as Fig. 2, the positioning locating surface C 40 in lens barrel of prism is with A, B perpendicularity within 0.005MM.
The present invention relates to the positioning of prism in full shot, reduces the processing request to prism and lens barrel, Ke Yiyou
Effect reduces cost, of the invention compared with existing full shot prism positions, and has suitable clear advantage, first our rib
Mirror is directly to be glued on eyeglass, does not just have to the positioning for considering prism during the design of such lens barrel, and the requirement of the perpendicularity in Fig. 2 is just
Eliminate, the structure of such lens barrel can be relatively easy, difficulty of processing relative reduction；Secondly the machining accuracy of single prism is than needing
Glued prism required precision is low, as long as ensureing 1 45 ° ± 30 in Fig. 1 mono- ", so relatively glued integral prism
Difficulty of processing is reduced, and prism can also be glued on other eyeglasses according to design requirement.
In the description of specification, reference term " conjunction one embodiment ", " preferably ", " example ", " specific example " or
The description of " some examples " etc. means specific features, structure, material or the feature for combining the embodiment or example description, comprising
In at least one embodiment or example of the present invention, not necessarily referred in this manual for the schematic representation of above-mentioned term
Be identical embodiment or example.Moreover, specific features, structure, material or the feature of description can be at any one
Or combined in a suitable manner in multiple embodiments or example.
From the foregoing description of structures and principles it should be understood by those skilled in the art that, not office of the invention
It is limited to above-mentioned embodiment, this hair is all fallen within using the improvement and replacement of techniques well known on the basis of the present invention
Bright protection domain, it should be limited by each claim.
