Brief description of the drawings
Fig. 1 is the cross-sectional view of camera lens module provided by the invention.
Embodiment
To make the object, technical solutions and advantages of the present invention clearer, each reality below in conjunction with accompanying drawing to the present invention
The mode of applying is explained in detail.However, it will be understood by those skilled in the art that in each embodiment of the present invention,
In order that reader more fully understands the present invention and proposes many ins and outs.But even if without these ins and outs and base
Many variations and modification in following embodiment, each claim technical side claimed of the present invention can also be realized
Case.
As shown in figure 1, be a kind of camera lens module 100 provided by the invention, including：Lens barrel 11, it is arranged on inside lens barrel 11
Optical module 12.Wherein, the barrel 111 of lens barrel 11 is provided with screwed hole 112, and the screwed hole 112 runs through barrel 111, the mirror
Head mould group 100 also includes bolt 13, and bolt 13, which is matched and screwed in screwed hole 112 with screwed hole 112, supports optical module 12.
In the present embodiment, the screw-in depth by adjustment bolt 13 in screwed hole 112, so as to adjust optical module
12 position inside lens barrel 11, and finally realize the axiality and concentricity of the internal optical 12 of adjustment camera lens module 100
Purpose, on the other hand, after it ensure that good axiality and concentricity, can effectively improve the light of camera lens module 100
Performance is learned, wherein, the screw-in depth of bolt 13 can specifically be realized by adjusting its rotating cycle.
The quantity of screwed hole 112 can set 1, and 1 can of screwed hole 112 is realized to optical module 12 in lens barrel 11
Internal position adjustment, but 1 screwed hole 112 is merely able to realize the adjustment in a rectilinear direction, it is more preferable in order to realize
It is multi-direction on position adjustment effect, the quantity of screwed hole 112 can also set multiple namely at least two, rotate respectively not
Bolt 13 on equidirectional adjusts screw-in depth and realized, it is preferred that opening 112a of multiple screwed holes 112 close to optical axis O sides
It is arranged at equal intervals on the barrel 111,112 equidistant set-up mode of screwed hole so that bolt 13 is to optical module 12
Resist force uniformly act on optical module 12, this ensure that optical module 12 can be on the basis of adjustment position, also
Can firmly it be fixed on lens barrel 11.
It is noted that the quantity of screwed hole 112 is preferably even number, and screwed hole 112 is close to optical axis O sides
Opening 112a is arranged on the barrel 111 of lens barrel 11 two-by-two facing each otherly.Be arranged such so that two relative bolts 13 from
The direction of two faces supports optical module 12, when the position of optical module 12 carries out position adjustment, as long as position will be needed
Two bolts 13 difference precession of face, back-out lens barrel 11, simple to operate on adjustment direction.
Specifically, optical module 12 can be eyeglass or shadow shield.For example, when optical module 12 is eyeglass,
During use, lens position may because its loosening or because itself production precision is not high cause axiality between eyeglass and
Concentricity is not high, now passes through the depth that adjustment bolt 13 screws in screwed hole 112, it is possible to adjust the position of eyeglass, and and then
Adjust the axiality and concentricity between eyeglass；When optical module 12 is anti-dazzling screen, equally appears in and above-mentioned use process
Middle position loosens or itself not high situation of production precision, now can also screw in screwed hole 112 by adjustment bolt 13
Depth, and by adjusting the position of anti-dazzling screen, and then adjust the axiality and concentricity between anti-dazzling screen and eyeglass.Need to illustrate
, it will be appreciated by those skilled in the art that optical module 12 can also be specifically other any in camera lens module 100
A kind of optical module 12.
Preferably, camera lens module 100 also includes being arranged on screwed hole 112 away from the deep gouge at the side opening 112b of optical axis O mono-
113, bolt 13 includes being contained in end 132 in deep gouge 113, and is connected with end 132 and screws in the screw thread of screwed hole 112
Portion 131.It is understood that deep gouge 113 is a kind of preferable structure, deep gouge 113 is set on barrel 111 so that bolt 13
End 132 be able to be contained in deep gouge 113, certainly, even if without deep gouge 113, this is not interfered with present embodiment most yet
The realization of whole technique effect.
Opened it is noted that one end of the adjacent end 132 of threaded portion 131 is threaded to screwed hole 112 away from optical axis O sides
During the concordant position of mouthful 112b, side of the end 132 away from threaded portion 131 is submerged in deep gouge 113.Specifically, when bolt 13
When screwing in bosom, end 132 is submerged in deep gouge 113, and the end 132 will not protrude the barrel 111 of lens barrel 11, therefore will not be by
False touch is touched, it ensure that the reliability of camera lens module 100.
Opened it should be noted that the one end of threaded portion 131 away from end 132 is threaded to screwed hole 112 close to optical axis O sides
During the concordant position of mouthful 112a, side of the end 132 away from threaded portion 131 is concordant with the barrel 111 of lens barrel 11.It is arranged such,
So that the length value of bolt 13 is not more than the thickness value of barrel 111, when bolt 13 is not completely screwed into, end 132 also exists
In deep gouge 113, this end 132 for avoiding bolt 13 causes to be touched by false touch because of prominent lens barrel 11, and and then change bolt 13
The depth of screw-in, so as to change the position of optical module 12, this ensure that camera lens mould while axiality and concentricity is improved
The reliability of group 100.
Certainly, the quantity of screwed hole 112 can also be odd number, and screwed hole 112 is close to opening 112a of optical axis O sides etc.
Spacing is arranged on barrel 111.For example, when the quantity of screwed hole 112 is three, three screwed holes 112 are around lens barrel 1
Optical axis O is arranged on the barrel 111 of lens barrel 11 at equal intervals, when the position for needing to adjust optical module 12 to ensure axiality and same
When the heart is spent, as long as 3 bolts 13 to be coordinated to the adjustment for being screwed in, being screwed out.
The invention further relates to a kind of location regulation method of optical module 12 in lens barrel 11, the lens barrel 11 and optical module 12
Lens barrel 11 and optical module 12, this method as shown in Fig. 1 are specially：Barrel is provided through on the barrel 111 of lens barrel 11
111 screwed hole 112, bolt 13 is screwed in screwed hole 112 and supports the optical module 12 in lens barrel 11；Swivel bolt 13,
The position of optical module 12 is adjusted by the screw-in depth of bolt 13.
It is noted that screwed hole 112 can be arranged to the radial direction extension along lens barrel 11, in this way, rotation can be made
Enter the bolt 13 in screwed hole 112 preferably to support and fix optical module 12.It can be changed according to the pitch size of screwed hole 112
Calculate the relation of the rotating cycle of bolt 13 and precession/back-out depth, and by the number of turns of adjustment bolt 13 come control the precession of bolt 13,
The distance of lens barrel 11 is screwed out, so as to adjust the position of optical module 12, is finally reached the axiality of adjustment optical module 12 in real time
With the purpose of concentricity.
It will be understood by those skilled in the art that the respective embodiments described above are to realize the specific embodiment of the present invention,
And in actual applications, can to it, various changes can be made in the form and details, without departing from the spirit and scope of the present invention.
