Abstract
Description
- 1. Field of the Invention
- The present invention relates generally to photographing devices, and more particularly, to a lens module.
- 2. Description of the Related Art
- As the digital products have been diversified, such as personal digital assistants (PDA), mobile phones, or other small portable terminal apparatuses, each of them is broadly combined with a miniature photographing device, like lens module, to have photographing function. In the early application to such digital products, the lens modules are mostly formed of fixed-focus lenses which fail to adjust the local length and then to vividly photograph landscape at short range.
- To provide the consumers with better photographic quality, the manufacturer developed a miniature lens module for adjustment of local length.
FIG. 1 illustrates a focusing miniature lens module, which is composed of a base A1, a focusing ring A2, a holding member A3, and a lens barrel A4. The focusing ring A2 includes a plurality of recessions A21 formed at an internal sidewall thereof. Each of the recessions A21 has at least two positioning portions A22 a and A22 b and an inclined portion A23. The positioning portions A22 a and A22 b are formed at a bottom side of the focusing ring A2 and located axially at different positions of the same. The inclined portion A23 is located between the two positioning portions A22 a and A22 b. The focusing ring A2 further includes a plurality of lugs A24 formed on an external edge thereof. The base A1 includes an upright annular wall A11, and a plurality of convex portions A12 protruding outward from an external edge thereof and corresponding to the recessions A21 and having the same number as the recessions A21. The focusing ring A2 is fitted onto the upright annular wall A11 of the base A1 to enable the positioning portions A22 a to lie against the corresponding convex portions A12. The holding member A3 is mounted onto the base A1, having a plurality of holding tongues A31 corresponding to the lugs A24 respectively and holding the corresponding lugs A24 for enabling the positioning portions A22 a to closely lie against the corresponding convex portions A12. The lens barrel A4 is mounted onto the focusing ring A2 for receiving a set of lenses. - In light of the above, when the focusing ring A2 is rotated on the upright annular wall A11, the focusing ring A2 lies against the convex portions A12 and then moves along the inclined portion A23 from the positioning portion A22 a to the other positioning portion A22 b. Because the two positioning portions A22 a and A22 b of each recession A21 are located axially at different positions of the focusing ring A2, when the focusing ring A2 lies against the convex portions A12 and then moves along the inclined portion A23 from the positioning portion A22 a to the other positioning portion A22 b, the axial distance between the focusing ring A2 and the base A1 is subject to change for adjustment of the local length.
- The aforementioned lens module A is defective in that the concentricity between the lens set in the lens barrel A4 and the image sensor B is subject to deviation, because the lens barrel A4 mounted onto the focusing ring A2 is subject to rotation along with the focusing ring A2 while rotated, to depart the focus spot of the lens set from the image sensor B where images ought to be received, further affecting the imaging quality.
- The primary objective of the present invention is to provide a lens module, in which the concentricity between the lens set in the lens barrel and the image sensor, while the focusing is done, is never subject to deviation to maintain good imaging quality.
- The foregoing objective of the present invention is attained by the lens module, which is composed of a base, a focusing ring, and a combination holder, and the primary feature lies in that the focusing of the lens module is done by the focusing ring and the combination holder.
- The focusing ring is rotatably mounted to the base, having a ring body and at least one driving portion formed on a torus thereof. The driving portion has at least two positioning portions and at least one inclined portion in connection with the two positioning portions. The two positioning portions are located at different radial positions of the ring body. The combination holder is fitted onto the focusing ring to be rotatable on an internal sidewall of the ring body of the focusing ring. The combination holder has at least one convex portion contacting against one of the two positioning portions. The combination holder is provided for combination with a lens barrel that a lens set is received.
- In light of the above, rotate the focusing ring to enable the convex portion to contact against the combination holder to move along the inclined portion from one of the positioning portions to the other, so that the combination holder is axially moved to change the axial distance between the combination holder and the base, finally attaining the focusing effect.
- In the process of the above-mentioned focusing, the combination holder is only axially moved other than rotated to thus prevent the lens set in the lens barrel from deviation of the concentricity between the lens set and the image sensor.

Thebarrel 60 is mounted onto thecombinative holder 30 in such a way that theexternal thread 61 is fitted with theinternal thread 311. - When the lens module 1 is mounted onto a main body of a camera (not shown), the image sensor (not shown) of the camera is located at a bottom side of the
base 10. According to the aforementioned structure, the lens module 1 of this embodiment can be set with two focal lengths as recited below. - The status of the lens module 1 set with the first focal length is recited below.
- Referring to
FIGS. 3 and 4 , when theextension portion 22 of the focusingring 20 is located at a first position of thebase 10, what the focusingring 20 contacts against theconvex portions 34 respectively are the positioningportions 212 a. Because thepositioning portions 212 a are close to thebase 10 and thecombinative holder 30 is held by the wavelikeresilient ring 40 to enable theconvex portions 34 to closely lie against the positioningportions 212 a respectively, thecombinative holder 30 is located at a position close to thebase 10, where the first focal length is set between the lens set and the image sensor. - The status of the lens module 1 set with the second focal length is recited below.
- Referring to

In the meantime, what the focusingring 20 contacts against theconvex portions 34 respectively are transferred from the positioningportions 212 a through theinclined portions 213 to theother positioning portions 212 b respectively while theextension portion 22 reaches the second position. While theinclined portions 213 keep contacting against theconvex portions 34, thecombinative holder 30 is moved on itself away from thebase 10. When what the focusingring 20 contacts against theconvex portions 34 respectively are transferred to thepositioning portions 212 b, thecombinative holder 30 reaches a position farther away from thebase 10, where the second focal length is set between the lens set and the image sensor. - In the focusing of the lens module 1 of this embodiment, because the corresponding two
combinative columns 12 contact against two sides of the limitingportion 33 of thecombinative holder 30 respectively to hold thecombinative holder 30 from rotation. Therefore, thecombinative holder 30 does not rotate during the axial movement of thecombinative holder 30. In light of this, during the focusing of the lens module 1 of this embodiment, the concentricity between the lens set and the image sensor is never subject to deviation to prevent the focus point of the lens set from departure from where the image sensor is supposed to receive the image, further maintaining due imaging quality after the distance between an object and the lens set is changed. - According to the above-mentioned description, the present invention delicately uses the two elements, i.e. the rotatable focusing ring and the combinative holder, to attain the focusing of the lens module and to ensure the imaging quality of the lens module. Such design not only effectively improves the drawbacks of the lens module but also effectively simplifies each element of the present invention to reduce the production cost.
- Although the present invention has been described with respect to a specific preferred embodiment thereof, it is no way limited to the details of the illustrated structures but changes and modifications may be made within the scope of the appended claims.
