It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale, and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings, in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series, and the like.
In at least one embodiment, the circuit board 10 may be a flexible circuit board, a rigid circuit board, or a rigid-flexible circuit board. In an embodiment, the circuit board 10 is a rigid-flexible circuit board including a first rigid portion 101, a second rigid portion 102, and a flexible portion 103 connecting the first rigid portion 101 and the second rigid portion 102. At least one electronic connecting element 20 is mounted on a surface of the second rigid portion 102. When the lens module 100 is applied to an electronic device 200 (shown in
A photosensitive chip 21 and a plurality of electronic components 22 are mounted on a same surface of the first rigid portion 101. In at least one embodiment, the photosensitive chip 21 and the plurality of electronic components 22 may be mounted on different surfaces of the first rigid portion 101. The plurality of electronic components 22 may be at least one of resistors, capacitors, diodes, triodes, relays and electrically erasable programmable read-only memory (EEPROM), or the like.
The lens holder 30 is mounted on the surface of the first rigid portion 101 by a first adhesive layer 23 where the photosensitive chip 21 and the plurality of electronic components 22 are mounted. Referring to

In at least one embodiment, referring to
In at least one embodiment, the metal support 40 may be darkened by an oxidation treatment.
The metal support 40 includes a support plate 401, heat dissipation plates 402, and heat transfer plates 403 connecting between the support plate 401 and the heat dissipation plates 402. In at least one embodiment, the metal support 40 may be made of copper or aluminum.
Referring to
The filter 50 corresponds to the photosensitive chip 21. The filter 50 is sandwiched between the support portion 406 and the stepped surface 320.
In at least one embodiment, the number of the heat dissipation plates 402 is two, and the number of the heat transfer plates 403 is two. The two heat dissipation plates 402 are located on two opposite sides of the support plate 401. In at least one embodiment, the two heat transfer plates 403 are respectively installed in two first mounting holes 33, so that the two heat dissipation plates 402 are respectively located on a side of the first sidewall 3011 facing away from the third sidewall 3013 and a side of the third sidewall 3013 facing away from the first sidewall 3011. Each of the heat dissipation plates 402 includes a base 4020 and a plurality of heat dissipation fins 4021 on a surface of the base 4020. A surface of the base 4020 facing away from the plurality of heat dissipation fins 4021 connects the heat transfer plate 403. In at least one embodiment, the base 4020 is perpendicular to the heat transfer plate 403. The plurality of heat dissipation fins 4021 increases a surface area of the heat dissipation plate 402, thereby increasing a heat dissipation capability of the heat dissipation plate 402.
The metal support 40 may further include at least one positioning member 404. Each positioning member 404 extends from the connecting portion 408 in a direction away from a central axis of the opening 41. Each positioning member 404 is received in one of the at least one second mounting hole 34. In at least one embodiment, the metal support 40 includes four positioning members 404, two of the four positioning members 404 are installed in the second mounting holes 34 on the second sidewall 3012, and the others are installed in the second mounting holes 34 on the fourth sidewall 3014.
The first holder portion 301 and the second holder portion 302 may be formed separately or integrally formed. In at least one embodiment, the first holder portion 301 and the second holder portion 302 are integrally formed. The first holder portion 301 and the second holder portion 302 may be made of plastic, such as polyethylene.
The lens 60 is partially received in the receiving hole 31. The lens 60 may include a first lens portion 601, a second lens portion 602, a third lens portion 603, a fourth lens portion 604, and a fifth lens portion 605 stacked orderly. In at least one embodiment, a width of the third lens portion 603 is greater than a width of the second lens portion 602 and is greater than a width of the fourth lens portion 604. In at least one embodiment, a width of the fifth lens portion 605 is greater than the width of the fourth lens portion 604. In at least one embodiment, a width of the first lens portion 601 is greater than the width of the second lens portion 602.
Referring to
Since the metal support 40 may improve a strength of the lens holder 30, a thickness of the lens holder 30 may be reduced, thereby reducing a height of the lens module 100 and miniaturizing the lens module 100. The metal support 40 is performed by a black oxide process, thereby preventing light from reflecting on the metal support 40. A stray light of the lens module 100 may be improved, and an imaging quality of the lens module 100 may be improved. The filter 50 sandwiched between the support portion 406 and the stepped surface 320 may prevent the filter 50 from breaking when the lens module 100 falls, thereby enhancing a reliability of the lens module 100. In addition, since the heat dissipation plates 402 are outside the lens holder 30, the heat generated by the lens module 100 can be transmitted to the heat dissipation plates 402 and radiated to the external environment by the heat dissipation plates 402, thereby enhancing a heat dissipation capability of the lens module 100 and the imaging quality of the lens module 100.
It is to be understood, even though information and advantages of the present embodiments have been set forth in the foregoing description, together with details of the structures and functions of the present embodiments, the disclosure is illustrative only; changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present embodiments to the full extent indicated by the plain meaning of the terms in which the appended claims are expressed.
