The mobile terminal 1000 includes a housing assembly 200 and a camera module 300.

The housing assembly 200 of the present embodiment includes a housing 12, a first bezel 14, a second bezel 16, and a cover 18. The housing 12 is formed with a through hole 121 and a mounting groove 122 surrounding the through hole 121. The first decorative ring 14 is installed in the installation groove 122 and protrudes out of the installation groove 122 in the axial direction (e.g., the Y direction in fig. 2) of the through hole 121, the first decorative ring 14 is provided with a first through hole 141, and the first through hole 141 corresponds to the through hole 121. The second decorative ring 16 is mounted on the first decorative ring 14, the second decorative ring 16 is opened with a second through hole 161, and the second through hole 161 corresponds to the through hole 121. The cover plate 18 is mounted on the second bezel 16, the cover plate 18 includes a base 181 and a light-transmissive lens 182, the lens 182 is detachably mounted on the base 181, and the lens 182 corresponds to the second through hole 161.

The camera module 300 is disposed corresponding to the through hole 121.

The mobile terminal 1000 according to the embodiment of the present invention utilizes the first decoration ring 14 and the second decoration ring 16 to form a protruding structure outside the housing 12, so as to avoid directly stamping the housing 12 to form an outward protrusion, on one hand, the mobile terminal 1000 has an original protrusion function, and simultaneously, the housing 12 has a simple structure, on the other hand, the mobile terminal avoids the defects of cracks or wrinkles caused by stamping, and the like, and improves the manufacturing yield.

In addition, the lens 182 is transparent and corresponding to the second through hole 131, and light can pass through the lens 182 to reach the camera module 300 without requiring the transparency and wear resistance of the material of the base 181, thereby reducing the material cost of the cover plate 18.

Referring to fig. 1 and 2, a mobile terminal 1000 according to an embodiment of the invention includes a housing assembly 200 and a camera module 300. The housing assembly 200 includes a housing 12, a first bezel 14, a second bezel 16, and a cover 18.

The housing 12 may be a rear cover of the mobile terminal 1000, for example, a battery cover of a mobile phone, and correspondingly, the camera module 300 may be a rear camera module of the mobile terminal 1000 for recording and shooting scenes.

Referring to fig. 2 and 3, in particular, the housing 12 includes an outer surface 123 and an inner surface 124, wherein the outer surface 123 forms a part of an appearance of the mobile terminal 1000, and the inner surface 124 is a surface opposite to the outer surface 123. The housing 12 further defines a through hole 121 and a mounting groove 122 surrounding the through hole 121. Perforations 121 extend through outer surface 123 and inner surface 124, and perforations 121 may be circular, square, etc. in shape. The mounting groove 122 is opened on the outer surface 123, and the mounting groove 122 does not penetrate the inner surface 124. The mounting groove 122 may be a continuous groove surrounding the through hole 121, or may be a plurality of discontinuous grooves spaced around the through hole 121. The material of the housing 12 may be an aluminum alloy, so as to ensure that the housing 12 has good plasticity and strength, and to facilitate the light weight of the mobile terminal 1000. Of course, the material of the housing 12 may be a non-metallic material such as plastic or resin.

Referring to fig. 2 and 3, the first decorative ring 14 has a first through hole 141, and the first through hole 141 corresponds to the through hole 121. The first bezel 14 may be annular, such as circular, oval, racetrack, etc. The first bezel 14 is mounted in the mounting groove 122 of the housing 12 and protrudes out of the mounting groove 122 in an axial direction (e.g., Y direction in fig. 2) of the through hole 121, and the first bezel 14 and the housing 12 can be connected by welding or bonding, specifically, a part of the first bezel 14 is located in the mounting groove 122, and another part is located outside the mounting groove 122. The portion of the first decorative ring 14 located in the mounting groove 122 is matched with the mounting groove 122, and the mounting groove 122 has a limiting effect on the first decorative ring 14, so as to prevent the first decorative ring 14 from moving in a plane perpendicular to the axis of the through hole 121 under the action of an external force (e.g., in the X direction in fig. 2), specifically, if the through hole 121 is a circular hole, the mounting groove 122 can limit the first decorative ring 14 from moving in the radial direction of the through hole 121 under the action of the external force.

A portion of the first bezel 14 outside the mounting slot 122 can be decorative to the mobile terminal 1000, such as by coating or sputtering a fluorescent material to enhance the aesthetic appearance of the mobile terminal 1000. The material of the first bezel 14 may be identical to the material of the housing 12 so that the same treatment is applied to the appearance of the first bezel 14 and the housing 12 during the manufacturing process, and the consistency of the appearance of the first bezel 14 to the housing 12 is high when the first bezel 14 is mounted on the housing 12. Specifically, the first bezel 14 may also be an aluminum alloy material to facilitate the shaping of the first bezel 14. In addition, since the first decorative ring 14 protrudes out of the mounting groove 122 in the axial direction of the through hole 121, the first decorative ring 14 actually provides more space for arranging the camera module 300 in the axial direction (Y direction), so that the camera module 300 can pass through the through hole 121 without increasing the thickness of other positions of the mobile terminal 1000, which is beneficial to realizing the lightness and thinness of the mobile terminal 1000. The second decorative ring 16 is mounted on the first decorative ring 14, the second decorative ring 16 is opened with a second through hole 161, and the second through hole 161 corresponds to the through hole 121. The second bezel 16 may be annular as a whole, and the second bezel 16 may have the same shape as the first bezel 14 as a whole, for example, an annular shape, an elliptical shape, a racetrack shape, or the like.

Referring to fig. 2, the lens 182 is detachably connected to the base 181. In one embodiment, referring to FIG. 5, the base 181 has a mounting hole 1812 formed therein, the mounting hole 1812 is aligned with the second through hole 161, and the lens 182 can be mounted in the mounting hole 1812. Specifically, the lens 182 may be adhered to the hole wall of the mounting hole 1812 by glue, which is preferably reversible, and the adhesion force of the glue is weakened to make it easy to remove the lens 182 from the mounting hole 1812, for example, after irradiating the adhesion surface with laser light. The lens 182 may be snap fit into the mounting hole 1812, for example, the outer wall of the lens 182 may be formed with a protrusion, the wall of the mounting hole 1812 may be formed with a groove, and aligning the lens 182 with the mounting hole 1812 and pressing the lens 182 may cause the protrusion to snap into the groove to mount the lens 182 into the mounting hole 1812.

The lens 182 may be a sapphire or the like material having both good optical transparency and wear resistance. The material of the substrate 181 may be the same as the material of the lens 182. The material of the substrate 181 may also be different from that of the lens 182, and specifically, the substrate 181 may be an opaque material so that the substrate 181 can shield the circuit structure of the camera module 300; the material of the base 181 may be metal (e.g., aluminum, copper, etc.), nonmetal (e.g., glass, resin, rubber), alloy of various metals (e.g., stainless steel, zinc-aluminum alloy, aluminum-lithium alloy, etc.), and alloy of metal and nonmetal (e.g., iron-carbon alloy, etc.). In one example, the material of the base 181 may be identical to the material of the housing 12, so that the appearance of the base 181 and the housing 12 is treated the same during the manufacturing process, and the consistency between the appearance of the base 181 and the housing 12 is high.

Referring to fig. 2, the camera module 300 is disposed corresponding to the through hole 121. Specifically, the camera module 300 is aligned with the through hole 121. More specifically, the optical axis of the camera module 300 coincides with the axis of the through hole 121. The camera module 300 may protrude from the outer surface 123 of the housing 12 and extend into the second through hole 161, providing more space for the arrangement of the camera module 300 in the axial direction (Y direction). Moreover, since the camera module 300 is disposed corresponding to the through hole 121, the through hole 121 corresponds to the first through hole 141, and the through hole 121 corresponds to the second through hole 161, the camera module 300 is disposed corresponding to the through hole 121, the first through hole 141, and the second through hole 161. The camera module 300 can receive external light to form an image, which can be a picture or a video.

The mobile terminal 1000 according to the embodiment of the present invention utilizes the first decoration ring 14 and the second decoration ring 16 to form a protruding structure outside the housing 12, so as to avoid directly stamping the housing 12 to form an outward protrusion, on one hand, the mobile terminal 1000 has an original protrusion function, and simultaneously, the housing 12 has a simple structure, on the other hand, the mobile terminal avoids the defects of cracks or wrinkles caused by stamping, and the like, and improves the manufacturing yield. In addition, the lens 182 is transparent and corresponding to the second through hole 131, and light can pass through the lens 182 to reach the camera module 300 without requiring the transparency and wear resistance of the material of the base 181, thereby reducing the material cost of the cover plate 18.

In some embodiments, the number of perforations 121, first through-holes 141, and second through-holes 161 are all single.

Correspondingly, the number of the lenses in the camera module 300 is single, and the single lens passes through the through hole 121 and the first through hole 141 in sequence and then passes through the second through hole 161.

Referring to fig. 2 and 4, in some embodiments, the number of the through holes 121, the first through holes 141 and the second through holes 161 is two, the housing 12 further includes a reinforcing plate 125 separating the two through holes 121, and the first bezel 14 abuts against the reinforcing plate 125.

The first bezel 14 abuts against the mounting groove 122 and also abuts against the reinforcing plate 125, so that the bonding area of the first bezel 14 and the housing 12 is large, and the reliability of bonding the first bezel 14 and the housing 12 is increased. Further, the reinforcing rib 1251 is formed on the reinforcing plate 125, and the reinforcing rib 1251 further increases the strength of the reinforcing plate 125, thereby preventing the reinforcing plate 125 from being deformed and damaged.

Referring to fig. 6, the two through holes 121 may have the same size and shape, for example, both the two through holes 121 are circular, square, triangular, and the like, so that the molds for manufacturing the two through holes 121 may be the same, thereby saving the manufacturing cost. Of course, the size and shape of the two through holes 121 may not be completely equal according to actual requirements, for example, when the sizes of the camera modules 300 respectively corresponding to the two through holes 121 are different, the sizes of the two through holes 121 may also be different in order to adapt to the size difference of the camera modules 300. Similarly, the size and shape of the two first through holes 141 and the two second through holes 161 are similar to those of the two through holes 121, and are not described herein again.

Correspondingly, the number of the camera modules 300 may be two, and each camera module 300 is installed corresponding to one through hole 121. Specifically, the optical axis of each camera module 300 coincides with the axis of a corresponding one of the through holes 121. The two camera modules 300 may be controlled by the processor of the mobile terminal 1000 to provide a better user experience.

Specifically, in one example, two camera modules 300 may be imaged simultaneously to optimize imaging quality. For example, two camera modules 300 simultaneously image a plurality of frames of the first image and a plurality of frames of the second image. The processor of the mobile terminal 1000 may analyze the multiple frames of the first image and the multiple frames of the second image to screen out a frame of image with the optimal imaging quality as a final image. Or the processor performs fusion or splicing processing on the first image and the second image to realize the enhancement of the color or the definition of the final image.

In another example, one camera module 300 may be used to assist another camera module 300 in imaging, thereby optimizing the imaging quality. For example, one camera module 300 first detects the brightness of the current scene, and the processor analyzes the detected brightness value to control the exposure time of the photosensitive element corresponding to each pixel in the other camera module 300, so as to obtain an image with proper brightness. Therefore, the problem of overexposure or low brightness of the finally obtained image can be avoided, and the quality of the image obtained by the camera module 300 is improved.

In yet another example, two camera modules 300 can be turned on in sequence to perform imaging, thereby optimizing the imaging quality. For example, one camera module 300 employs a wide-angle lens, and the other camera module 300 employs a telephoto lens. When imaging is needed, the camera module 300 using the wide-angle lens is firstly started to perform imaging, and if the mobile terminal 1000 detects that the user performs the operation of magnifying the preview image and the magnification ratio exceeds a preset value, the camera module 300 using the telephoto lens is immediately started to perform imaging. So, because the visual field of wide-angle lens is great, the focus is shorter, and the visual field of telephoto lens is less, and the focus is great, indicates that the user wants to shoot farther scenery when the user carries out preview picture magnification operation, adopts the telephoto lens just to enable to shoot clear long shot this moment, consequently, switches to camera module 300 that adopts the telephoto lens in order to form images in order to promote the image definition who obtains.

Referring to fig. 2 and 4, in some embodiments, the first bezel 14 includes a first spacer 142, the first spacer 142 separates two first through holes 141, and the first spacer 142 is combined with the reinforcing plate 125. The second bezel 16 includes a second spacer plate 162, the second spacer plate 162 separating the two second through holes 161, the second spacer plate 162 being combined with the first spacer plate 142.

The first partition plate 142 reinforces the strength of the first bezel 14, and the second partition plate 162 reinforces the strength of the second bezel 16, so that the entire structure of the case assembly 200 is more stable. The first spacing plate 142 and the reinforcing plate 125, and the second spacing plate 162 and the first spacing plate 142 may be fixedly connected by gluing, clamping, welding, or the like. The first spacing plate 142 may not be fixedly connected to the reinforcing plate 125, and the first spacing plate 142 is directly carried on the reinforcing plate 125. The second spacer plate 162 may not be fixedly connected to the first spacer plate 142, and the second spacer plate 162 is directly supported on the first spacer plate 142.

In the embodiment of fig. 2 and 4, the first spacing plate 142 is connected to the reinforcing plate 125 by gluing. Specifically, the reinforcing plate 125 is in a flat plate shape, the first partition plate 142 is formed with a combination groove 1421, when the first partition plate 142 and the reinforcing plate 125 need to be connected, glue is dispensed on the reinforcing plate 125, the combination groove 1421 and the reinforcing plate 125 are aligned and installed, so that part of the reinforcing plate 125 is placed in the combination groove 1421, and after the glue is cured, the first partition plate 142 and the reinforcing plate 125 are fixedly connected. Meanwhile, after the first partition board 142 is fixedly connected to the reinforcing board 125, the reinforcing board 125 is located between the sidewalls 1422 of the combining groove 1421, and the sidewalls 1422 limit the reinforcing board 125 from shaking left and right, so that the relative position between the first bezel 14 and the housing 12 is relatively stable. In other embodiments, the reinforcing plate 125 may be completely received in the coupling groove 142.

In the embodiment of fig. 2 and 4, the second partition plate 162 is coupled with the first partition plate 142 by gluing.
