Detailed Description

The following is a preferred embodiment of the present application, and it should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications are also considered as the protection scope of the present application.

Before the technical solutions of the present application are introduced, the technical problems mentioned in the background art will be first described in detail.

In the related art, the rear case of the electronic device is made of an opaque material, or a decorative layer is formed on the surface of the rear case, so that the rear case is opaque. Therefore, a camera hole needs to be formed in the rear shell, so that incident light can pass through the rear shell to reach the camera module and be received by the camera module. Because the camera shooting hole is formed in the surface of the rear shell, the processing difficulty of the rear shell is increased, and water or dust is easy to enter the electronic equipment, so that the camera decorating part is usually arranged at the camera shooting hole to seal the camera shooting hole, but the camera decorating part usually protrudes out of the surface of the rear shell, so that the surface of the rear shell is uneven, and the electronic equipment cannot be horizontally placed on a desktop. And when electronic equipment falls, camera decoration is very easily damaged.

In order to solve the above problems, the present application provides a back shell assembly, which is matched with a back shell and a diaphragm, so that a camera shooting hole does not need to be formed in the back shell, the surface of the back shell assembly is flat, and the above mentioned problems are solved.

Please refer to fig. 1 and fig. 2 together. Fig. 1 is a schematic structural diagram of a rear housing assembly according to a first embodiment of the present application. Fig. 2 is a schematic view of fig. 1 when an incident light ray passes through the rear housing assembly. The embodiment provides a rear shell assembly 1, the rear shell assembly 1 includes a rear shell 10 and a diaphragm 20, the rear shell 10 is made of a transparent material, and the diaphragm 20 is adhered to one side of the rear shell 10. The film 20 includes a transparent region 21 and a non-transparent region 22, and the transparent region 21 is used for transmitting incident light from the transparent region 21.

The back case assembly 1 is one of important components in the electronic device 2. The rear case 10 not only functions to support and protect other components within the electronic device 2, but also may form a gorgeous color on the surface of the rear case 10 to increase the color diversity of the electronic device 2. The rear shell 10 also needs to make external incident light enter the camera module 4 inside the electronic device 2 through the rear shell 10, so that the camera module 4 receives the light to realize a shooting function. The material of the rear housing 10 in the rear housing assembly 1 of the present embodiment is transparent, so that incident light can pass through the rear housing 10. In addition, in the present embodiment, a diaphragm 20 is additionally provided at one side of the rear case 10, so that incident light can be transmitted through the light-transmitting region 21 and blocked by the non-light-transmitting region 22. Therefore, through the cooperation of the rear case 10 and the diaphragm 20, the rear case 10 does not need to be provided with a camera hole, and the incident light can pass through the rear case 10 and the diaphragm 20 to reach the camera module 4 without installing a camera decoration, thereby replacing the technical scheme of providing a camera hole in the rear case 10 and installing a camera decoration in the related art. Therefore, the rear housing assembly 1 provided by the embodiment reduces the processing difficulty and cost of the rear housing 10, simplifies the structure of the rear housing assembly 1, improves the flatness of the rear housing assembly 1, enables the rear housing assembly 1 to be flatly placed on a desktop, and when the rear housing assembly 1 falls, the rear housing assembly is not easy to damage, and improves the structural stability of the rear housing assembly. In addition, since the rear case 10 of the present application is integrated, the surface does not need to be perforated, and thus the rear case assembly 1 is not easily penetrated with water. The sealability of the rear case assembly 1 is improved. The specific positional relationship between the rear case 10 and the diaphragm 20 in the rear case assembly 1, and the specific structure of the light-transmitting region 21 in the diaphragm 20 will be described in detail later.

Referring to fig. 1 again, in the present embodiment, the rear housing 10 includes an appearance surface 11 and a non-appearance surface 12 that are oppositely disposed, where the appearance surface 11 is a surface that can be directly seen by a user, and the non-appearance surface 12 is located in the electronic device 2 and is a surface that cannot be seen by the user in a complete state. The membrane 20 is bonded to the non-design side 12. In the present embodiment, the film 20 is bonded to the non-exterior surface 12, and it can also be understood that the film 20 is disposed inside the electronic device 2, which is beneficial to protect the film 20, so that the film 20 is not easily affected by the external environment and falls off from the rear case 10, and the user can see the film 20 disposed inside the electronic device 2 through the rear case 10 made of transparent material.

Referring to fig. 3, fig. 3 is a structure of a rear housing assembly according to a second embodiment of the present application. The structure of the rear case assembly 1 according to the second embodiment of the present application is substantially the same as the structure of the rear case assembly 1 according to the first embodiment of the present application, except that the diaphragm 20 is bonded to the exterior surface 11 in the present embodiment. Adhering the membrane 20 to the outer surface 11 may provide better protection to the rear housing 10 and may also provide better viewing of the membrane 20 by a user.

Referring to fig. 4, fig. 4 is a structure of a rear housing assembly according to a third embodiment of the present application. The structure of the rear housing assembly 1 provided in the third embodiment of the present application is substantially the same as the structure of the rear housing assembly 1 provided in the first embodiment of the present application, except that in the present embodiment, the diaphragm 20 is provided with a light-transmitting hole 23, and the light-transmitting hole 23 is disposed corresponding to the light-transmitting area 21. The light holes 23 are formed in the diaphragm 20, so that incident light can better penetrate through the diaphragm 20, the distortion effect of the incident light is reduced, and the accuracy of the incident light received by the camera module 4 is improved. Alternatively, the light transmission holes 23 are entirely disposed corresponding to the light transmission regions 21.

Referring to fig. 5, fig. 5 is a structure of a rear housing assembly according to a fourth embodiment of the present application. The structure of the rear housing assembly 1 provided in the fourth embodiment of the present application is substantially the same as the structure of the rear housing assembly 1 provided in the first embodiment of the present application, except that in the present embodiment, the membrane 20 includes a substrate 200 and a decoration layer 210 disposed on one side of the substrate 200, and the decoration layer 210 is closer to the rear housing 10 than the substrate 200.

In this embodiment, the diaphragm 20 generally includes a base 200, the base 200 is a substrate for supporting other structures of the diaphragm 20, and the material of the base 200 includes, but is not limited to, Polyethylene terephthalate (PET). Decorative layer 210 is a layer structure having a gorgeous color, which can provide visual effects of different colors. The decorative layer 210 is close to the rear case 10 compared to the substrate 200 so that a user can directly see the various colors of the decorative layer 210 through the rear case 10. Optionally, the decoration layer 210 further has a micro-nano structure of a light effect that changes with a user viewing angle. For example, a user viewing the back shell assembly 1 from different angles may see different colored decorative layers 210. Or the user can see the decorative layer 210 with the same color but different shades and brightnesses by looking at the rear housing assembly 1 from different angles.

Referring to fig. 5 again, in the present embodiment, the material of the film 20 is a transparent material, and the decoration layer 210 is disposed corresponding to the opaque region 22. In the present embodiment, the decoration layer 210 is disposed corresponding to the opaque region 22, so that the decoration layer 210 blocks incident light, and the transparent region 21 without the decoration layer 210 allows incident light to pass through. In addition, since the film 20 of the present embodiment is made of a transparent material, it is not necessary to form the light-transmitting hole 23 in the light-transmitting region 21 to allow incident light to pass through the film 20.

Referring to fig. 6, fig. 6 is a structure of a rear housing assembly according to a fifth embodiment of the present application. The structure of the rear housing assembly 1 provided in the fifth embodiment of the present application is substantially the same as the structure of the rear housing assembly 1 provided in the fourth embodiment of the present application, except that in the present embodiment, the diaphragm 20 further includes a light shielding layer 220, the light shielding layer 220 is disposed in the non-light-transmitting region 22, the light shielding layer 220 corresponds to the periphery of the light-transmitting region 21, the light shielding layer 220 is disposed on one side of the base 200, and the light shielding layer 220 is closer to the rear housing 10 than the base 200.

In the present embodiment, the light-shielding layer 220 is disposed at the periphery of the light-transmitting region 21, and optionally, the color of the light-shielding layer 220 is black. The light shielding layer 220 can prevent the influence of stray light on incident light, and can also prevent the incident light from crosstalk, thereby improving the image pickup effect of the camera module 4. As to the specific position relationship of the light shielding layer 220 in the film 20, the present application provides two embodiments, please refer to fig. 6 again, and the light shielding layer 220 and the decoration layer 210 are disposed in the same layer. In this embodiment, the light-shielding layer 220 and the decoration layer 210 can be located on the same layer and prepared by different processes. Optionally, when the color of the decoration layer 210 is black, since the color of the light shielding layer 220 is also black, the light shielding layer 220 and the decoration layer 210 can be prepared by one process, so that the preparation time and the process cost of the rear housing assembly are reduced.

Referring to fig. 7, fig. 7 is a structure of a rear housing assembly according to a sixth embodiment of the present application. The structure of the rear case assembly 1 according to the sixth embodiment of the present application is substantially the same as the structure of the rear case assembly 1 according to the fifth embodiment of the present application, except that in the present embodiment, the diaphragm 20 further includes a transparent adhesive layer 230, and the transparent adhesive layer 230 is disposed between the decorative layer 210 and the rear case 10. In the present embodiment, the film 20 is adhered to the rear case 10 through the transparent adhesive layer 230, and since the transparent adhesive layer 230 is made of a transparent material, a user can observe the color of the decoration layer 210 through the transparent adhesive layer 230. In the present embodiment, since the decoration layer 210 and the light-shielding layer 220 are disposed on the same layer, the transparent adhesive layer 230 is disposed on the decoration layer 210 and the light-shielding layer 220, and it can also be understood that the transparent adhesive layer 230 is disposed only corresponding to the non-light-transmitting region 22, and is not disposed on the light-transmitting region 21, thereby further improving the transmission effect of the incident light.

Referring to fig. 8, fig. 8 is a structure of a rear housing assembly according to a seventh embodiment of the present application. The structure of the rear housing assembly 1 provided in the seventh embodiment of the present application is substantially the same as that of the rear housing assembly 1 provided in the sixth embodiment of the present application, except that in the present embodiment, the light shielding layer 220 is disposed on a side of the decoration layer 210 facing away from the substrate 200. In the present embodiment, the light-shielding layer 220 is disposed on a side of the decoration layer 210 away from the substrate 200, that is, the light-shielding layer 220 is disposed on the decoration layer 210, so that the processing difficulty of the decoration layer 210 and the light-shielding layer 220 can be reduced. When the light-shielding layer 220 is disposed on the decoration layer 210, the light-shielding layer 220 and the transparent adhesive layer 230 can be disposed on the same layer. Optionally, a side of the light shielding layer 220 facing away from the decoration layer 210 is flush with a side of the transparent adhesive layer 230 facing away from the decoration layer 210.

In addition, due to the arrangement of the transparent adhesive layer 230, a distance exists between the light-transmitting hole 23 and the rear case 10, which is the thickness of the transparent adhesive layer 230, and optionally, the thickness of the transparent adhesive layer 230 is 0.01-0.05 mm. The increased distance between the light hole 23 and the rear case 10, i.e., the increased thickness of the transparent adhesive layer 230, reduces the amount of incident light, thereby reducing the light intensity of the incident light and improving the image pickup effect. However, the thickness of the transparent adhesive layer 230 cannot be too large, and for example, when the thickness of the transparent adhesive layer 230 is greater than 0.05mm, the amount of incident light is too small, and the incident light intensity is too low, thereby affecting the image capturing effect. If the thickness of the transparent adhesive layer 230 is too small, for example, if the thickness of the transparent adhesive layer 230 is less than 0.01mm, the adhesive effect of the transparent adhesive layer 230 is too poor, and the membrane sheet 20 cannot be firmly adhered to the rear case 10. Further optionally, the transparent adhesive layer 230 has a thickness of 0.02-0.03 mm.

Referring to fig. 9, fig. 9 is a structure of a rear housing assembly according to an eighth embodiment of the present application. The structure of the rear housing assembly 1 according to the eighth embodiment of the present application is substantially the same as the structure of the rear housing assembly 1 according to the seventh embodiment of the present application, except that in the present embodiment, one side of the light shielding layer 220 close to the rear housing 10 has a micro-nano structure with a light effect that changes with a change of a user viewing angle. Since the color of the light shielding layer 220 is black, in the embodiment, the micro-nano structure is disposed on one side of the light shielding layer 220 close to the rear housing 10, so that a user can see visual effects of different brightness of black at different angles, such as bright black or frosted black.

Referring to fig. 10, fig. 10 is a top view of the diaphragm of fig. 9. In this embodiment, the light-transmitting area 21 is circular, the light-shielding layer 220 is annular, and the light-shielding layer 220 surrounds the light-transmitting area 21. Since the lens of the camera module 4 is circular, the light-transmitting area 21 is circular and the light-shielding layer 220 is annular in the present embodiment, which improves the matching with the camera module 4 and improves the image capturing effect.

Referring to fig. 11 and 12 together, fig. 11 is a structure of a rear housing assembly according to a ninth embodiment of the present application. Fig. 12 shows a structure of a rear case assembly according to a tenth embodiment of the present application. The structure of the rear housing assembly 1 according to the ninth and tenth embodiments of the present application is substantially the same as the structure of the rear housing assembly 1 according to the sixth embodiment of the present application, except that in the ninth and tenth embodiments, the diaphragm 20 further includes a light exit region 24, the light exit region 24 is used for emitting an outgoing light ray from the light exit region 24, and the light blocking ratio of the light blocking layer 220 close to the light exit region 24 is greater than the light blocking ratio of the light blocking layer 220 far from the light exit region 24.

In this embodiment, the light emitting area 24 is used for emitting emergent light, for example, light of a flash lamp in the camera module 4, so as to supplement light. However, since the light-exiting region 24 can be disposed only on one side of the light-transmitting region 21, a portion of the light-shielding layer 220 disposed around the light-transmitting region 21 is closer to the light-exiting region 24. Therefore, in the present embodiment, the light-shielding rate of the light-shielding layer 220 close to the light-exiting region 24 is controlled to be greater than the light-shielding rate of the light-shielding layer 220 far from the light-exiting region 24, so that the light-shielding effect of the light-shielding layer 220 close to the light-exiting region 24 is equal to the light-shielding effect of the light-shielding layer 220 far from the light-exiting region 24, thereby making the light more uniform and improving the image capturing effect. For a specific implementation manner of making the light-shielding layer 220 close to the light-exiting region 24 have a light-shielding rate greater than that of the light-shielding layer 220 far from the light-exiting region 24, the present application may control the light-shielding rate by controlling the concentration of the light-shielding layers 220 at different positions, for example, making the concentration of the light-shielding layer 220 close to the light-exiting region 24 greater than that of the light-shielding layer 220 far from the light-exiting region 24, so that the light-shielding layer 220 close to the light-exiting region 24 has a light-shielding rate greater than that of the light-shielding layer 220 far from the light-exiting region 24. Alternatively, the light-shielding rate may be controlled by controlling the thickness of the light-shielding layer 220 at different positions, for example, the thickness of the light-shielding layer 220 close to the light-exiting region 24 is greater than the thickness of the light-shielding layer 220 far from the light-exiting region 24, so that the light-shielding layer 220 close to the light-exiting region 24 has a greater light-shielding rate than the light-shielding layer 220 far from the light-exiting region 24.

Referring to fig. 11 again, the light-transmitting region 21 includes a first sub light-transmitting region 210 and a second sub light-transmitting region 211, the first sub light-transmitting region 210 is disposed closer to the light-emitting region 24 than the second sub light-transmitting region 211, the light-shielding layer 220 includes a first sub light-shielding layer 221 and a second sub light-shielding layer 222, the first sub light-shielding layer 221 is disposed corresponding to a periphery of the first sub light-transmitting region 210, the second sub light-shielding layer 222 is disposed corresponding to a periphery of the second sub light-transmitting region 211, and a light-shielding rate of the first sub light-shielding layer 221 is greater than a light-shielding rate of the second sub light-shielding layer 222. When the number of the light-transmitting regions 21 is plural, for example, the number of the light-transmitting regions 21 is two, and the light-transmitting region 21 includes the first sub light-transmitting region 210 and the second sub light-transmitting region 211, the light-shielding rate of the first sub light-shielding layer 221 can be greater than that of the second sub light-shielding layer 222, so that the light-shielding effect of the first sub light-shielding layer 221 is equal to that of the second sub light-shielding layer 222. As shown in fig. 11, the thickness of the first sub-light-shielding layer 221 is greater than that of the second sub-light-shielding layer 222, that is, the side of the first sub-light-shielding layer 221 facing away from the substrate 200 is higher than the side of the decoration layer 210 facing away from the substrate 200, and the side of the second sub-light-shielding layer 222 facing away from the substrate 200 is flush with the side of the decoration layer 210 facing away from the substrate 200.

Referring to fig. 12 again, the light-shielding layer 220 includes a third sub-light-shielding layer 223 and a fourth sub-light-shielding layer 224, the third sub-light-shielding layer 223 is closer to the light-emitting area 24 than the fourth sub-light-shielding layer 224, and the light-shielding rate of the third sub-light-shielding layer 223 is greater than that of the fourth sub-light-shielding layer 224. For a single light-transmitting region 21, the third sub-shielding layer 223 is closer to the light-emitting region 24 than the fourth sub-shielding layer 224, and the light-shielding effect of the light-shielding layer 220 can be unified by controlling the light-shielding rate of the third sub-shielding layer 223 to be greater than that of the fourth sub-shielding layer 224 in this embodiment. As shown in fig. 12, the concentration of the third sub-light shielding layer 223 is greater than that of the fourth sub-light shielding layer 224, that is, the concentration of the ink for preparing the third sub-light shielding layer 223 is greater than that of the ink for preparing the fourth sub-light shielding layer 224 when the light shielding layer 220 is prepared.
