Referring to fig. 1 and fig. 2, a mobile terminal 1000 according to an embodiment of the present invention may be an electronic device with a photographing function, such as a mobile phone, a tablet computer, a smart watch, a head-up display device, and the like, and the following description only takes the mobile terminal 1000 as a mobile phone as an example. The mobile terminal 1000 includes a housing assembly 200 and a camera module 300.

Referring to fig. 2 and 3, a housing assembly 200 according to an embodiment of the present invention includes a housing 12, a first bezel 14, and a second bezel 16. 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 mounted in the mounting groove 122 and protrudes out of the mounting groove 122 in the axial direction (e.g., Y direction in fig. 2) of the through hole 121, and the first decorative ring 14 is provided with a single first through hole 141, and the first through hole 141 corresponds to the through hole 121. The second decorative ring 16 is installed on the first decorative ring 14, two second through holes 161 are opened on the second decorative ring 16, and the two second through holes 161 correspond to the first through holes 141.

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.

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, and a second bezel 16.

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 single 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 installed on the first decorative ring 14, two second through holes 161 are opened on the second decorative ring 16, and the second through holes 161 correspond to the first through holes 141. 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. In the embodiment of the present invention, the two second through holes 161 correspond to the single first through hole 141, and the center lines of the two second through holes 161 may be arranged in parallel with each other, and the center lines of the two second through holes 161 are parallel to the center line of the first through hole 141.

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 two second through holes 161 correspond to the first through hole 141, 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.

Referring to fig. 2 and 4, in some embodiments, the number of the through holes 121 is two, the housing 12 further includes a reinforcing plate 125 separating the two through holes 121, and the first bezel 16 abuts against the reinforcing plate 125.

The second bezel 16 is attached to the first bezel 14 and also abuts against the reinforcing plate 125, so that the attachment area of the second bezel 16 is increased, and the attachment reliability of the second bezel 16 is improved. 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. In the embodiment of the present invention, the two through holes 121 correspond to the first through hole 141, and the center lines of the two through holes 121 may be arranged in parallel with each other, and the center lines of the two through holes 121 are parallel to the center line of the first through hole 141.

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 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 second bezel 16 includes a spacer plate 162, the spacer plate 162 separates two second through holes 161, and the spacer plate 162 is combined with the reinforcing plate 125.

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

In the embodiment of fig. 2 and 4, the spacing plate 162 and the reinforcing plate 125 are connected by gluing. Specifically, the spacing plate 162 includes a body 1623 and a coupling protrusion 1621 formed on the body 1623, the coupling protrusion 1621 abuts against the reinforcing plate 125, and a glue accommodating space 1622 is formed between the body 1623, the coupling protrusion 1621 and the reinforcing plate 125. When the partition 162 and the reinforcing plate 125 are fixedly connected, glue may be dispensed on the reinforcing plate 125, the combining protrusion 1621 abuts against the reinforcing plate 125, the glue is accommodated in the glue accommodating space 1622, and after the glue is cured, the partition 162 and the reinforcing plate 125 are fixedly connected.

Referring to fig. 2 and 3, in some embodiments, the first bezel 14 includes a bottom surface 143 and a mounting protrusion 144 protruding from the bottom surface 143, the bottom surface 143 is a surface of the first bezel 14 away from the second bezel 16, and the mounting protrusion 144 abuts against a bottom 1223 of the mounting slot 122 to form a gap 1221 between the bottom surface 143 and the bottom 1223 of the mounting slot 122.

The gap 1221 may be used to accommodate glue to fixedly attach the first bezel 14 to the housing 12. Specifically, the mounting protrusion 144 may be a continuous annular protrusion, and the mounting protrusion 144 may also be composed of a plurality of spaced sub-protrusions. When the first decorative ring 14 is installed, glue can be dispensed in the installation groove 122, and then the installation protrusion 144 abuts against the bottom 1223 of the installation groove 122, so that the glue is accommodated in the gap 1221, and after the glue is cured, the first decorative ring 14 is fixedly connected with the housing 12.

Referring to fig. 2 and 3, in some embodiments, the mounting protrusion 144 of the first decorative ring 14 abuts against the side wall of the mounting groove 122 to block foreign materials from entering the through hole 121 from the mounting groove 122.

Specifically, the installation protrusion 144 may be annular, the annular installation protrusion 144 abuts against the side wall of the installation groove 122, the installation protrusion 144 blocks the outside and the gap 1221, the outside impurities (water vapor, dust, etc.) cannot enter the installation groove 122, and the camera module 300 is prevented from being polluted by the outside impurities, thereby improving the image quality.

Referring to fig. 2 and 5, in some embodiments, the housing 12 includes an outer surface 123 and an inner surface 124, the through hole 121 penetrates the outer surface 123 of the housing 12 and the inner surface 124 of the housing 12, the outer surface 123 of the housing 12 is closer to the second bezel 16 than the inner surface 124 of the housing 12, the first bezel 14 further includes a sealing protrusion 146, the sealing protrusion 146 extends from an outer peripheral surface 145 of the first bezel 14, the sealing protrusion 146 abuts against the outer surface 123 of the housing 12, and the mounting protrusion 144 of the first bezel 14 is used for blocking the gap 1221 and the through hole 121.

Specifically, the outer peripheral surface 145 of the first bezel 14 is an appearance surface that the user can see the mobile terminal 1000, and the outer peripheral surface 145 of the first bezel 14 and the outer surface 123 of the housing 12 may be the same color, so that the appearance consistency of the first bezel 14 and the housing 12 is high. The sealing protrusion 146 abuts against the outer surface 123 of the housing 12, the combination area of the first decorative ring 14 and the housing 12 is increased, the combination stability of the first decorative ring 14 and the housing 12 is good, and the sealing protrusion 146 can block external impurities to prevent the impurities from entering the mounting groove 122.

The mounting protrusion 144 of the first bezel 14 may be spaced apart from the sidewall 1222 of the mounting slot 122, the mounting protrusion 144 of the first bezel 14 may be spaced apart from the through hole 121 by a gap 1221 and the through hole 121, the gap 1221 may be used to receive glue when gluing the first bezel 14 to the housing 12, and the mounting protrusion 144 of the first bezel 14 prevents the glue from flowing into the through hole 121. In one example, the mounting protrusion 144 of the first bezel 14 is connected to the wall of the through hole 121 to increase the size of the gap 1221 as much as possible, and further increase the glue capacity of the gap 1221, so that the first bezel 14 is firmly combined with the housing 12.

Of course, in other embodiments, the first bezel 14 may not be provided with the mounting protrusion 144, and when the first bezel 14 is mounted on the housing 12, the bottom surface 143 of the first bezel 14 directly abuts against the bottom 1223 of the mounting groove 122.
