Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It should be noted that the description relating to "first", "second", etc. in the present invention is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

A lens assembly implementing various embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in themselves. Thus, "module" and "component" may be used in a mixture.

The lens assembly may be implemented in various forms. For example, the terminal described in the present invention may include a lens assembly having a communication function, such as a mobile phone, a smart phone, a notebook computer, a digital broadcast receiver, a PDA (personal digital assistant), a PAD (tablet computer), a PMP (portable multimedia player), a navigation device, and the like. In the following, it is assumed that the terminal is a lens assembly. However, it will be understood by those skilled in the art that the configuration according to the embodiment of the present invention can be applied to a fixed type terminal in addition to elements particularly used for moving purposes.

An embodiment of the present invention provides a mobile terminal 1. Referring to fig. 1 and fig. 2, the mobile terminal 1 includes: a body 2 and a lens assembly 3.

The body 2 may have a substantially flat rectangular parallelepiped shape. The front of the machine body 2 can be provided with a screen 4, which is convenient for a user to operate and observe, and of course, the screen 4 can be omitted according to the requirement or design.

The lens assembly 3 may be mounted on one side of the body 2, for example, the lens assembly 3 may be mounted on one side of the back of the body 2, so that a user can conveniently take a picture or photograph while watching the screen 4; of course, the lens assembly 3 may also be mounted on one side of the front surface of the body 2 according to the requirement or design, so as to facilitate the user to view the screen 4 and take a picture at the same time.

Referring to fig. 3 and 4, the lens assembly 3 may include: a carrier 30 and a filter 31.

The top of the bracket 30 is provided with a recess 300. For example, the bracket 30 may have a substantially flat rectangular parallelepiped shape. The thickness of the bracket 30 may be 0.66mm, and the depth of the recess 300 may be 0.61mm, so that the thickness of the bottom of the bracket 30 may be 0.05 mm.

The filter 31 is mounted in the recess 300 of the bracket 30. The filter 31 may be an IR filter 31(infrared filter 31). The thickness of the filter 31 may be 0.2 mm.

In the mobile terminal 1 provided in this embodiment, the filter 31 is accommodated in the recess 300 of the bracket 30, so that the thickness of the lens assembly 3 can be reduced, and the phenomenon that the lens assembly 3 protrudes from the body 2 of the mobile terminal 1 is improved.

Optionally, referring to fig. 3 to fig. 5, a stopping portion 302 extends from an inner side wall of the recess 300 of the bracket 30 toward a center of the recess 300 of the bracket 30, and the stopping portion 302 is spaced apart from the inner wall of the recess 300 of the bracket 30. The stopper 302 presses against the filter 31. For example, the top of the stopping portion 302 may be flush with the top of the recess 300, and the thickness of the stopping portion 302 may be 0.4mm, so that the distance between the bottom of the stopping portion 302 and the bottom wall of the recess 300 is 0.21mm, and the filter 31 with the thickness of 0.2mm may be just placed. The recess 300 may be substantially rectangular, the stopping portions 302 may surround four inner sidewalls of the recess 300 of the bracket 30, and the stopping portions 302 may be disposed on the same or different inner sidewalls of the recess 300 of the bracket 30 at intervals. Thus, the filter 31 is clamped between the inner wall of the recess 300 and the stopper 302, so that the filter 31 is stably mounted.

Optionally, the top of the optical filter 31 is accommodated in the recess 300 of the bracket 30, for example, the thickness of the bracket 30 may be 0.66mm, the depth of the recess 300 may be 0.61mm, the top of the stopping portion 302 may be flush with the top of the recess 300, and the thickness of the stopping portion 302 may be 0.4mm, so that the distance between the bottom of the stopping portion 302 and the bottom wall of the recess 300 is 0.21mm, and the optical filter 31 with the thickness of 0.2mm can be just placed. Of course, according to the requirement or design, one or more of the thicknesses of the bracket 30 and the stopper 302 and the depth of the recess 300 are adjusted, the top of the optical filter 31 may be flush with the top of the bracket 30, or the top of the optical filter 31 may extend out of the recess 300 of the bracket 30. In this way, the thickness of the lens assembly 3 can be reduced, thereby improving the protrusion of the lens assembly 3 from the body 2 of the mobile terminal 1.

Optionally, with continuing reference to fig. 3, the lens assembly 3 further includes: a lens 33, an image sensor 34, and a circuit board 35.

The lens 33 is disposed above the bracket 30. The lens 33 may be a CMOS lens, for example.

The image sensor 34 is disposed below the carriage 30.

The image sensor 34 is electrically connected to the circuit board 35. For example, the circuit board 35 may be an RFPC (flexible hard combined circuit board).

The lens 33 and the image sensor 34 are aligned with the optical filter 31, and the bottom wall of the recess 300 is corresponding to the optical filter 31 for transmitting light. For example, a through hole is opened on the bottom wall of the recess 300 corresponding to the filter 31 or made of a light-transmitting material. Thus, the image pickup and photographing functions of the lens 33 are realized.

Optionally, the lens assembly 3 further comprises a driving device 36. The driving device 36 is mounted on the bracket 30, and the driving device 36 is connected to the lens 33 to drive the lens 33 to move away from or close to the image sensor 34. For example, the driving device 36 is vcm (voice Coil motor). This allows control of the focal length.

Optionally, the bracket 30 includes a first portion and a second portion (not shown). The first part is provided with a first groove penetrating through the first end of the first part, and the second part is provided with a second groove penetrating through the first end of the second part. The first end of the first portion is pivotally connected to the first end of the second portion to enable the first portion to move from a first position to a second position relative to the second portion; when the first portion is in the first position, the first recess aligns with the second recess to form the recess 300; the first groove is distal from the second groove when the first portion is in the second position. Thus, when the optical filter 31 needs to be installed, the first portion is located at the second position, the optical filter 31 is placed between the first groove and the second groove, and the first portion is rotated to be located at the first position, so that the optical filter 31 can be accommodated in the recess 300. When the optical filter 31 needs to be installed, the first part is turned to enable the first part to rotate to the second part from the first position, and then the optical filter 31 is taken out. Thus, the optical filter 31 can be easily removed or attached.

A second embodiment of the present invention provides a lens assembly 3 as described above.

In the lens assembly 3 provided in this embodiment, the filter 31 is accommodated in the recess 300 of the bracket 30, so that the thickness of the lens assembly 3 can be reduced.

A third embodiment of the present invention provides a bracket 30 as described above.

In the carrier 30 of the present embodiment, the filter 31 is accommodated in the recess 300 of the carrier 30, so that the thickness of the lens assembly 3 can be reduced.
