As shown in fig. 1 and 2, the back cover assembly 10 of the present disclosure includes a back cover 11, a decorative assembly 12, and a lens 13. As shown in fig. 1 and 2, the rear cover 11 includes an inner side surface and an outer side surface which are disposed opposite to each other, the inner and outer sides being opposite directions, the outer side surface being a surface which can be directly seen by a user, and the inner side surface being a surface opposite to the inner member.

In the present disclosure, as shown in fig. 1 and 2, one or more first through holes may be provided on the rear cover 11, and the first through holes may be used to provide various components, for example, a camera may be provided. In the present disclosure, the rear cover 11 may be made of plastic, or may be made of metal or ceramic, and the present disclosure is not limited thereto.

In the present disclosure, as shown in fig. 1 and 2, the decorative assembly 12 may include an insulating support 123 and a decorative piece 16, and the decorative piece 16 may include a metallic piece 121 and one or more structural members 122 connected to the metallic piece 121.

In the present disclosure, as shown in fig. 1 and 2, the metal piece 121 may be disposed above the structural member 122, i.e., the metal piece 121 may be disposed outside the structural member 122, and a stepped configuration may be present between the metal piece 121 and the structural member 122. However, the present disclosure is not limited thereto, and in some embodiments, the metallic member 121 and the structural member 122 may be integrated.

In the present disclosure, as shown in fig. 1 and 2, the structural member 122 may be connected with the rear cover 11. For example, the structural member 122 may be connected to the outer side surface of the rear cover 11. However, the present disclosure is not limited thereto, and in some embodiments, the structural member 122 may be coupled to the inner side surface of the rear cover 11.

In an exemplary embodiment of the present disclosure, as shown in fig. 1, the metal piece 121 may include a skirt 124, and the metal piece 121 may be connected with the structural member 122 through the skirt 124. As shown in fig. 1, the metal part 121 may press the structural part 122 by the skirt 124, thereby fixing the structural part 122 more firmly.

As shown in fig. 1 and 2, the metal member 121 is an outer part of the rear cover assembly 10, for example, when the rear cover assembly 10 is turned upside down on a table top, the metal member 121 may be in direct contact with the table top. In the present disclosure, the metal member 121 is provided as a metal housing, which may have better wear resistance, and is advantageous in improving the quality and service life of the rear cover assembly 10.

In an exemplary embodiment of the present disclosure, the structural member 122 may be a metallic material. When the structural member 122 is made of metal and the metal member 121 is also made of metal, the metal member 121 and the structural member 122 are subjected to high-gloss treatment, so that the surfaces of the metal member 121 and the structural member 122 are provided with a better appearance. However, the disclosure is not limited thereto, and in some embodiments, the structural member 122 may be made of plastic, ceramic.

In an exemplary embodiment of the present disclosure, as shown in fig. 1, the front projection on the first plane, i.e., the projection on the first plane along the thickness direction Z of the rear cover 11, the outer diameter of the structural member 122 may be larger than the outer diameter of the metal member 121. The first plane is perpendicular to the thickness direction Z of the rear cover 11, and may be considered to be parallel to the extension plane of the rear cover 11, and may be parallel to the horizontal plane when the rear cover assembly 10 is placed horizontally. In other words, along a plane section perpendicular to the thickness direction Z of the rear cover 11, in such a section, the outer diameter of the structural member 122 may be larger than the outer diameter of the metal member 121.

It should be noted that, in the orthographic projection of the first plane, the outer diameter of the structural member 122 may be larger than the outer diameter of the metal member 121. It will be appreciated that the outer diameter of the structural member 122 may be larger than the outer diameter of the metal member 121 in the projection on the first plane along the thickness direction Z of the rear cover 11.

This arrangement allows the structural member 122 to have a certain supporting effect on the metal member 121. Also, such an arrangement allows the user to see both the metallic member 121 and the structural member 122 at the same time, so that the outer surface of the rear cover assembly 10 as a whole can exhibit a more excellent appearance arrangement.

In an exemplary embodiment of the present disclosure, as shown in fig. 1 and 2, the insulating support 123 may be a plastic support, which is lighter in weight, and is advantageous in reducing the overall weight of the rear cover assembly 10, and achieving the light and slim rear cover assembly 10. As shown in fig. 1 and 2, the insulating support 123 is disposed between the rear cover 11 and the lens 13, and the plastic material of the insulating support 123 can generate a certain buffering effect between the rear cover 11 and the lens 13, and avoid damage to the rear cover 11 and the lens 13 caused by the rigid support.

In an exemplary embodiment of the present disclosure, as shown in fig. 1 and 2, the decoration 16 may be provided at an outer side surface of the rear cover 11 and around the insulating holder 123.
