[0028] In order to more clearly understand the above objects, features and advantages of the present application, the solution of the present application will be further described below. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to fully understand the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present application, rather than all the embodiments.

[0030] The present application provides an electronic device, and the electronic device provided by the present application includes, but is not limited to, a flat electronic device and a foldable electronic device.

[0031] The electronic device may include a housing assembly and a camera module. The camera module may be located inside the housing assembly. The housing assembly may be used to protect the devices inside it. The camera module may be used to enable the electronic device to obtain functions such as images and instant video calls.

[0032] In some embodiments, the electronic device may further include a display screen. The display screen can be used to display images and is disposed opposite to the housing assembly. When a user uses the electronic device, the display screen faces the user, and the housing assembly faces away from the user.

[0033] Please refer to Figure 1 , Figure 1 which is a schematic diagram of the housing assembly provided in some embodiments of the present application. The housing assembly 100 provided in the embodiments of the present application may include a housing 1 and a decorative member 2. The decorative member 2 can be used to decorate the camera module.

[0034] In the embodiments of the present application, taking the housing 1 as the rear cover of the electronic device and the camera module as the rear camera module of the electronic device as an example for illustration. In some other embodiments, the housing 1 may also be the front cover of the electronic device, and the camera module may also be used as the front camera module. The present application does not limit this.

[0035] Please continue to refer to Figure 1 , the housing 1 may include an inner surface 11 and an outer surface 12 that face each other. Among them, the inner surface 11 of the housing 1 may face the inside of the housing 1, and the outer surface 12 of the housing 1 may face the outside of the housing 1.

[0036] A first skirt 14 may be provided at the edge of the housing 1. The first skirt 14 may extend in a direction away from the outer surface 12. Specifically, the first skirt 14 may extend from the edge of the housing 1 in the direction from the outer surface 12 to the inner surface 11, that is, the first skirt 14 may extend in a direction towards the inside of the housing 1.

[0037] A notch 13 may be formed on the outer surface 12 of the housing 1. Among them, in the direction from the outer surface 12 to the inner surface 11, the notch 13 may completely penetrate the housing 1, or the notch 13 may only penetrate a part of the housing 1.

[0038] Exemplarily, the notch 13 may be located at one side edge of the housing 1, or may be located at the connection of two adjacent edges of the housing 1. In the following description, taking the notch 13 located at the connection of two adjacent edges of the housing 1 as an example for illustration.

[0039] The decorative member 2 is disposed at the notch 13. Specifically, the decorative member 2 is connected to the housing 1, is located at the notch 13 of the housing 1, and may match the notch 13. Thus, the decorative member 2 with different shapes can be replaced, and the decorative member 2 can be individually designed in appearance, so that the decorative member 2 can be three-dimensionally displayed, which is beneficial to improving the aesthetics of the electronic device and further beneficial to improving the user experience.

[0040] A second skirt 21 may be provided at the edge of the decorative member 2. The second skirt 21 may extend towards the housing 1. Specifically, the second skirt 21 may extend from the edge of the decorative member 2 towards the housing 1.

[0041] The outer surface 12 of the second skirt 21 may be flush with the outer surface 12 of the first skirt 14. Specifically, the surface of the second skirt 21 away from the interior of the housing 1 is flush with the surface of the first skirt 14 away from the interior of the housing 1.

[0042] Thus, when the decorative member 2 is connected to the housing 1, the step difference caused by the assembly tolerance of the housing assembly 100 can be avoided through the first skirt 14 and the second skirt 21, thereby reducing the splicing step difference between the decorative member 2 and the housing 1. At the same time, problems such as gaps or poor overlapping of the housing assembly 100 caused by the decorative member 2 being concave or convex relative to the housing 1 can also be avoided, which is beneficial to improving the yield rate of the housing assembly 100 and further reducing the manufacturing cost of the electronic device.

[0043] For the housing assembly 100 according to the embodiment of the present application, by providing the first skirt 14 at the edge of the housing 1 and the second skirt 21 at the edge of the decorative member 2, the step difference caused by the assembly tolerance of the housing assembly 100 can be avoided, thereby reducing the splicing step difference between the decorative member 2 and the housing 1. At the same time, problems such as gaps or poor overlapping of the housing assembly 100 caused by the decorative member 2 being concave or convex relative to the housing 1 can also be avoided, which is beneficial to improving the yield rate of the housing assembly 100 and further reducing the manufacturing cost of the electronic device. In addition, the decorative member 2 is provided at the notch 13 of the housing 1, enabling the decorative member 2 to be designed separately, which is beneficial to improving the aesthetics of the electronic device and further enhancing the user experience.

[0044] Please refer to Figure 1 and Figure 2 , Figure 2 which is a perspective view of the housing assembly provided in some embodiments of the present application. In some embodiments, there may be a step difference between the decorative member 2 and the housing 1. The value range of the step difference is -0.07 mm to 0.07 mm. Specifically, when the notch 13 is located at the connection of two adjacent edges of the housing 1, there is a top step difference between the top of the decorative member 2 and the top of the housing 1, and a side step difference between the side of the decorative member 2 and the side of the housing 1. The value ranges of both the top step difference and the side step difference can be -0.07 mm to 0.07 mm. Thus, through the first skirt 14 and the second skirt 21, the size of the step difference between the decorative member 2 and the housing 1 can be ensured, and by restricting the value range of the step difference, the yield rate of the housing 1 can be improved while ensuring the quality and performance of the housing assembly 100.

[0045] Exemplarily, the value of the step difference between the decorative member 2 and the housing 1 can be -0.07 mm, -0.06 mm, -0.05 mm, -0.04 mm, -0.03 mm, -0.02 mm, -0.01 mm, 0 mm, 0.01 mm, 0.02 mm, 0.03 mm, 0.04 mm, 0.05 mm, 0.06 mm, 0.07 mm, etc.

[0046] Please refer to Figure 3 , Figure 3 , which is a side view of the housing assembly provided by some embodiments of the present application. In some embodiments, the first skirt 14 may include a first trimming portion 141 and a first retaining portion 142. The first trimming portion 141 may be located on the side of the first retaining portion 142 away from the housing 1. In the direction from the outer surface 12 to the inner surface 11, the value range of the extension length of the first trimming portion 141 is greater than or equal to 2 mm. Thus, by restricting the value range of the extension length of the first trimming portion 141, it is possible to avoid the length of the first trimming portion 141 being too small to reduce the splicing step difference between the decorative member 2 and the housing 1, which is beneficial to improving the quality and performance of the housing assembly 100.

[0047] Exemplarily, the value of the extension length of the first trimming portion 141 can be 2 mm, 3 mm, 4 mm, 5 mm, etc.

[0048] It should be noted that the first trimming portion 141 can perform CNC machining on the assembled housing assembly 100 after the decorative member 2 and the housing 1 are spliced, and the first trimming portion 141 can be removed, leaving the first retaining portion 142.

[0049] Please continue to refer to Figure 3 , in some embodiments, the second skirt 21 includes a second trimming portion 211 and a second retaining portion 212. The second trimming portion 211 is located on the side of the second retaining portion 212 away from the decorative member 2. In the direction from the outer surface 12 to the inner surface 11, the value range of the extension length of the second trimming portion 211 is greater than or equal to 1.5 mm. Thus, by restricting the value range of the extension length of the second trimming portion 211, it is possible to avoid the length of the second trimming portion 211 being too small to reduce the splicing step difference between the decorative member 2 and the housing 1, which is beneficial to improving the quality and performance of the housing assembly 100.

[0050] Exemplarily, the value of the extension length of the second trimming portion 211 can be 1.5 mm, 2 mm, 2.5 mm, 3 mm, etc.

[0051] It should be noted that the second trimming portion 211 can perform CNC machining on the assembled housing assembly 100 after the decorative member 2 and the housing 1 are spliced, and the second trimming portion 211 can be removed, leaving the second retaining portion 212.

[0052] Please refer to Figure 4 , Figure 4 which is a side view of the housing assembly provided for some other embodiments of the present application. In some embodiments, in the direction from the outer surface 12 to the inner surface 11, the extended length of the first retaining portion 142 ranges from 0.43 mm to 0.68 mm. Thus, by restricting the length of the first retaining portion 142, the overall thickness of the housing assembly 100 can be prevented from being too large, facilitating the connection of the housing assembly 100 to the middle frame of the electronic device. At the same time, it is also convenient to achieve the thin and light design of the electronic device.

[0053] Exemplarily, the extended length of the first retaining portion 142 can take values such as 0.43 mm, 0.45 mm, 0.47 mm, 0.49 mm, 0.5 mm, 0.52 mm, 0.54 mm, 0.56 mm, 0.58 mm, 0.6 mm, 0.62 mm, 0.64 mm, 0.66 mm or 0.68 mm, etc.

[0054] Please continue to refer to Figure 4 , in some embodiments, in the direction from the outer surface 12 to the inner surface 11, the extended length of the first retaining portion 142 ranges from 0.41 mm to 0.66 mm. Thus, by restricting the length of the second retaining portion 212, the overall thickness of the housing assembly 100 can be prevented from being too large, facilitating the connection of the housing assembly 100 to the middle frame of the electronic device. At the same time, it is also convenient to achieve the thin and light design of the electronic device.

[0055] Exemplarily, the extended length of the first retaining portion 142 can take values such as 0.41 mm, 0.43 mm, 0.45 mm, 0.47 mm, 0.49 mm, 0.5 mm, 0.52 mm, 0.54 mm, 0.56 mm, 0.58 mm, 0.6 mm, 0.62 mm, 0.64 mm or 0.66 mm, etc.

[0056] Please refer to Figure 5 , Figure 5 which is an exploded view of the housing assembly provided for some embodiments of the present application. In some embodiments, the housing 1 can be provided with an adhesive layer 15 and a dispensing layer 16. The adhesive layer 15 and the dispensing layer 16 are located between the decorative member 2 and the housing 1. The dispensing layer 16 is disposed on the outer periphery of the adhesive layer 15. Specifically, the dispensing layer 16 can be formed in a ring shape, and the adhesive layer 15 is located in the ring. Thus, by providing the adhesive, a larger bonding area can be provided for the decorative member 2, and by dispensing, a local adhesive area can be provided for the decorative member 2. By disposing the dispensing layer 16 on the outer periphery of the adhesive layer 15, the bonding accuracy can be improved while ensuring the adhesive strength and stability, thereby ensuring the connection strength between the housing 1 and the decorative member 2 while reducing the manufacturing cost of the housing assembly 100.

[0057] Please continue to refer toFigure 5 The thickness of the dispensing layer 16 ranges from 0.1 mm to 0.2 mm, and the thickness of the back adhesive layer 15 ranges from 0.15 to 0.2 mm. Herein, the "thickness" refers to the dimension of the dispensing layer 16 in the direction from the inner surface 11 to the outer surface 12. By restricting the thicknesses of the dispensing layer 16 and the back adhesive layer 15, it is possible to avoid a decrease in the connection strength between the decorative member 2 and the housing 1 due to a small thickness of the dispensing layer 16 or the back adhesive layer 15, and it is also possible to avoid an increase in the manufacturing cost of the housing assembly 100 due to a large thickness of the dispensing layer 16 or the back adhesive layer 15.

[0058] Exemplarily, the thickness of the dispensing layer 16 can take values such as 0.1 mm, 0.11 mm, 0.12 mm, 0.13 mm, 0.14 mm, 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm, 0.2 mm, etc. The thickness of the back adhesive layer 15 can take values such as 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm, 0.2 mm, etc.

[0059] Please continue to refer to Figure 5 In some embodiments, the housing assembly 100 may further include an anti - stamping mylar member 3. One side of the anti - stamping mylar member 3 is connected to the dispensing layer 16, and the other side is connected to the decorative member 2. Specifically, when the housing assembly 100 is assembled, the anti - stamping mylar member 3 is attached to the side of the decorative member 2 close to the housing 1, and the housing 1 with the first skirt 14 and the decorative member 2 with the second skirt 21 are assembled together through the dispensing layer 16 and the back adhesive layer 15 in a glue - bonding form, and then pressure is maintained. After the pressure - maintaining is completed, the housing assembly 100 with the first skirt 14 and the second skirt 21 is placed on a CNC fixture for adsorption and fixation, and then CNC machining is performed to remove the first trimming portion 141 and the second trimming portion 211.

[0060] Thus, by providing the anti - stamping mylar member 3, it is possible to prevent the ink on the inner surface 11 of the decorative member 2 from wrinkling due to the shrinkage during the curing of the glue, and it is possible to avoid the problem of poor appearance of the decorative member 2, which is beneficial to improving the quality and yield rate of the housing assembly 100, and further beneficial to reducing the manufacturing cost of the housing assembly 100.

[0061] Please continue to refer to Figure 5 In some embodiments, the thickness of the anti - stamping mylar member 3 ranges from greater than or equal to 0.13 mm. By restricting the value of the anti - stamping mylar member 3, it is possible to avoid the situation where the thickness of the anti - stamping mylar member 3 is too small to prevent the ink on the inner surface 11 of the decorative member 2 from wrinkling due to the shrinkage during the curing of the glue.

[0062] Exemplarily, the thickness of the anti - stamping mylar member 3 can take values such as 0.13 mm, 0.14 mm, 0.15 mm, 0.16 mm, etc.

[0063] Exemplarily, the anti-stamping mylar member 3 may include a foam layer and a mylar layer, wherein the thickness of the foam layer may be 0.1 mm and the thickness of the mylar layer may be 0.03 mm.
