Abstract
The invention relates to a lens module group, which comprises a first lens barrel, a second lens barrel and a third lens barrel which are arranged in sequence along the optical axis direction, wherein a lens is arranged in the second lens barrel, and internal threads are arranged at the two ends of the second lens barrel, and the first lens barrel and the third lens barrel are all provided with external threads matched with the internal threads. A clipping part is axially extended at the ends of the first lens barrel and the third lens barrel which are respectively close to one end of the second lens barrel, the clipping parts are provided with projections radially extending along the lens barrels, grooves are arranged at the internal thread positions at the two ends of the second lens barrel, therefore the clipping parts of the first lens barrel and the third lens barrel can be inserted into the second lens barrel and can be rotated in the second lens barrel. The total length and theposition of the lens module group in the focusing process are not changed, and a space for the lens module group to move backward and forward is not required to be arranged in a lens mount, thereby reducing the volume of a camera.
Description
Technical field
The present invention relates to a kind of camera lens module, relate in particular to a kind of adjustable focus camera lens module.
Background technology
Along with Development of Multimedia Technology, digital camera, video camera are more and more favored by consumers in general, when people's logarithmic code camera, video camera are pursued miniaturization, wish again can take the different image of far and near distance at same position, and obtain the distinct image picture, and the numerical camera mould that is applied to mobile phone also will satisfy compact requirement, and the camera of therefore focusing arises at the historic moment.
Camera lens module in the traditional camera is in the focusing process, often need to adjust the distance between camera lens module and the image sensing device, in this process, need the total axial length of camera lens module to change or the camera lens module moves along optical axis direction, so the space that can allow the camera lens module movable back and forth must be set in lens mount, thereby increase the volume of whole camera.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
See also Fig. 1 and Fig. 2, the camera lens module 100 that first embodiment of the invention provides comprises one first lens barrel 10, second lens barrel 20 and a trinocular tube 30.Described second lens barrel 20 is located between described first lens barrel 10 and the trinocular tube 30.
Described first lens barrel 10 have an external thread part 11 and one from described external thread part 11 to holding section 12 that second lens barrel, 20 directions are extended.Have external thread on the described external thread part 11, described holding section 12 has a projection 121 of radially extending along first lens barrel 10.Be appreciated that described protruding 121 also can be a plurality of.
Described trinocular tube 30 have an external thread part 31 and one from described external thread part 31 to holding section 32 that second lens barrel, 20 directions are extended.Have external thread on the described external thread part 31, described holding section 32 has a projection 321 of radially extending along trinocular tube 30.
Described second lens barrel 20 two ends are respectively equipped with internal thread part 21 and 22, are respectively applied for the external thread part 11 of first lens barrel 10 and the external thread part 31 of trinocular tube 30 to cooperate.Have internal thread on the described internal thread part 21 and 22, and its internal diameter is respectively greater than the external diameter of described holding section 12 and 32.The internal thread part 21 and 22 of described second lens barrel 20 has an axially extended groove 23 respectively, and when 100 assemblings of camera lens module, projection 121 and projection 321 can be inserted in second lens barrel 20 by described groove 23.Be provided with at least one eyeglass 24 in described second lens barrel 20, for making camera lens module 100 have zoom function, have at least in described first lens barrel 10 and the trinocular tube 30 and be provided with eyeglass in one, in the present embodiment, be respectively equipped with an eyeglass 13 and eyeglass 33 in described first lens barrel 10 and the trinocular tube 30.
Described second lens barrel 20 is near the internal diameter of first lens barrel, the 10 1 sides external diameter and projection 121 height sums greater than the holding section 12 of first lens barrel 10, thereby makes described holding section 12 to rotate in second lens barrel 20.Described second lens barrel 20 is near the internal diameter of the trinocular tube 30 1 sides external diameter and projection 321 height sums greater than the holding section 32 of trinocular tube 30, thereby makes described holding section 32 to rotate in second lens barrel 20.Described protruding 121 and protruding 321 can prevent camera lens module 100 when focusing, and the rotation of second lens barrel excessively breaks away from first lens barrel 10 or the trinocular tube 30.The external diameter of described holding section 12 should be greater than the internal diameter of the threaded portion 21 of second lens barrel 20 with projection 121 height sums, and the external diameter of described holding section 32 and projection 321 height sums should be greater than the internal diameters of the threaded portion 22 of second lens barrel 20.For making the projection 121 of described holding section 12 can insert in second lens barrel 20 and can rotate, described protruding 121 and the distance of the external thread part 11 of first lens barrel 10 should be greater than the length of the internal thread part 21 of second lens barrel 20.For making the projection 321 of described holding section 32 can insert in second lens barrel 20 and can rotate, described protruding 321 and the distance of the external thread part 31 of trinocular tube 30 should be greater than the length of the internal thread part 22 of second lens barrel 20.
Persons of ordinary skill in the art may appreciate that according to technical conceive of the present invention described camera lens module 100 also can have other corresponding change and distortion.
See also Fig. 3, the camera lens module 200 that second embodiment provided by the invention provides, the similar structure of the camera lens module that provides to first embodiment of the invention 100 is provided described camera lens module 200, its difference is that second lens barrel, 220 two ends are equipped with external thread part 221 and holding section 222, and having internal thread part 231 and groove 232 on first lens barrel 210 and the trinocular tube 230, described holding section 222 is identical with holding section 12 structures.
See also Fig. 4, the camera lens module 300 that the 3rd embodiment provided by the invention provides, the similar structure of the camera lens module that provides to first embodiment of the invention 100 is provided described camera lens module 300, its difference is that described second lens barrel 320 is provided with external thread part 322 and holding section 323 near trinocular tube 330 1 ends, and be provided with internal thread part 324 and groove 325 near first lens barrel, 310 1 ends, have internal thread part 331 and groove 332 on the described trinocular tube 330, have external thread part 311 and holding section 312 on first lens barrel 310, described holding section 323 is identical with holding section 12 structures with 312.
Described camera lens module can maintain static first lens barrel and trinocular tube, and only come the camera lens module is focused by rotating second lens barrel, thereby guarantee whole camera lens module total length and invariant position in the focusing process, thereby need not the space that makes the camera lens module movable back and forth is set in lens mount, thereby can reduce the volume of camera.In addition, the projection in the described camera lens module on the holding section can be avoided camera lens module second lens barrel in the zoom process to rotate and excessively break away from first lens barrel or trinocular tube.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection domain that all should belong to claim of the present invention with distortion.
