The first body 111 and the second body 121 are spliced into a plate-like member, and both side surfaces of the first body 111 and the second body 121 in the thickness direction of the garnish 100 are flush. The first and second exterior side walls 112, 122 are joined into a complete ring shape to form the exterior profile of the trim piece 100.

Meanwhile, since the edges of both the first portion 110 and the third portion 130 are opaque, light emitted/entered by the third portion 130 does not cross light to the first portion 110 or light emitted/entered by the first portion 110 does not cross light to the third portion 130. In addition, the whole decoration 100 is not transparent at the edge, so that the first portion 110 is not exposed to external light or affects the nearby light sensor/light module, and the overall (light sense, lamp) function and display effect are ensured. That is, the decoration 100 also has a light blocking function.

The back of the electronic device 1 is designed with various light sensors and lamps for emitting and receiving light sources, and the above design has good isolation effect, so that the judgment of the ambient light by the light sensor can be prevented from being influenced if the light sensor is influenced by the flash lamp, and the display effect of the main display screen module 20 or the back display module 50 which is adjusted accordingly is influenced.

In the embodiment of the present application, the decoration 100 may be circular, that is, the first body 111 and the second body 121 are spliced to form a circular plate, and the first outer sidewall 112 and the second outer sidewall 122 are spliced to form a circular ring.

The third outer sidewall 132 is opaque, so that the third light beam is prevented from being emitted from the third outer sidewall 132 to the position of the second optical device 300, and the third light beam is prevented from interfering with the second optical device 300. In the embodiment of the application, the back display module is closer to the decoration 100, so the third light beam may be the light beam emitted by the back display module.

In an embodiment of the present application, the light-transmitting area of the first portion 110 and/or the third portion 130 is provided with an effect layer for changing the light-transmitting effect of the first portion 110 and/or the third portion 130.

It is understood that the step 114 may be protruded from the first inner sidewall 113 of the first portion 110, and the height of the step 114 is smaller than that of the first body 111. The overlapping portion of the second portion 120 and the step 114 may be recessed downward, so that both side surfaces of the first portion 110 and the second portion 120 may be flush to increase the compactness of the decoration 100.

By providing the stepped portion 114, the first portion 110 and the second portion 120 are reliably connected, and structural strength of the garnish 100 is improved.

Further, the stepped portion 114 is provided with a positioning hole 115, and the positioning hole 115 penetrates the stepped portion 114 in the thickness direction of the garnish 100.

Alternatively, the stepped portion 114 may be provided with a positioning post 125, and a positioning hole 115 may be provided at a portion where the first portion 110 is laminated with the stepped portion 114. The positioning posts 125 and the positioning holes 115 cooperate to promote the stability of the connection of the first portion 110 and the second portion 120.

In some embodiments, first portion 110 and second portion 120 are integrally formed. Specifically, the first portion 110 and the second portion 120 may be integrally molded using an injection molding process. When the decoration 100 is manufactured, the first part 110 of the decoration 100 is injection molded by using a semitransparent material, the molded first part 110 is used as an in-mold piece, and the second part 120 is injection molded by using an opaque material, so that the decoration 100 is formed by the first part 110 and the second part 120. When the second portion 120 is injection-molded, the injection molding liquid flows into the positioning hole 115, the positioning column 125 is formed after the injection molding liquid in the positioning hole 115 is dried, and the positioning column 125 is embedded in the positioning hole 115, so that the connection strength between the first portion 110 and the second portion 120 is increased.

After the first portion 110 and the second portion 120 are injection molded into the decoration 100, the first outer sidewall 112 of the first portion 110 may be roughened, or a light shielding layer may be attached to the first outer sidewall 112, so that the first outer sidewall 112 is opaque.

The light guide column 500 may be made of polycarbonate, glass, epoxy, or the like. The light guide pillar 500 can efficiently transmit light inside. By providing the light guiding pillar 500 to guide the light beam that the first optical device 200 needs to receive or emit from the first portion 110 to below the second portion 120, the first optical device 200 may be disposed below the second portion 120 such that the first optical device 200 is blocked by the opaque second portion 120, so that the light transmittance of the first portion 110 may be designed to be higher.

In some embodiments, the light transmittance of the light-transmissive portion of the first portion 110 is between 4% and 10%. That is, the first body is translucent, and the light transmittance of the first body may be 4%, 5%, 6%, 7%, 8%, or 10%. The first body is provided to be translucent, not only to allow the first light beam to pass therethrough, but also to block the first optical device 200 to increase the aesthetic property.

The first protective layer 63 and the second protective layer 64 are attached to the first surface 611 of the rear cover 61.

In the embodiment of the present application, the first protection layer 63 may increase the mohs hardness of the light-transmitting region, preventing the surface of the light-transmitting region from being scratched. Therefore, by providing the protective layer at the position of the rear cover 61 corresponding to the light-transmitting region, the mohs hardness of the surface of the light-transmitting region can be increased, and the scratch-resistant and scratch-resistant effects can be increased, so that the picture display definition of the optical device corresponding to the light-transmitting region can be improved, and the display effect of the optical device can be further improved. For example, the mohs hardness of the light-transmitting region to which the first protective layer 63 is attached may be 7H (Hard).

In the embodiment of the present application, the second protection layer 64 may increase the mohs hardness of the light-transmitting region corresponding thereto, preventing the surface of the light-transmitting region from being scratched. Therefore, by disposing the second protective layer 64 at the position of the rear cover 61 corresponding to the light-transmitting region, the mohs hardness of the surface of the light-transmitting region can be increased, and the scratch-resistant and scratch-resistant effects can be increased, so that the light transmittance of the light-entering optical module corresponding to the light-transmitting region can be improved, and the light-entering optical module can be the camera module 40 or the first optical device 200. Thereby improving the effect of the optical device. For example, the mohs hardness of the light-transmitting region to which the second protective layer 64 is attached may be 7H.

The back cover assembly 60 or trim piece 100 further includes an electrochromic layer 66, the electrochromic layer 66 being disposed on a surface of the color layer 65 facing away from the back cover 61. The electrochromic layer 66 is used for adjusting the color and/or transparency of the light emitted from the light emitting optical module, which may be the second optical device 300 or the back display screen module 50, thereby improving the visual effect and the aesthetic appearance of the electronic device 1. It will be appreciated that the electrochromic layer 66 may be adhered and fixed to the surface of the color layer 65 facing away from the rear cover 61 by any one of an optical adhesive layer, an adhesive layer, and a double-sided adhesive layer. The electrochromic layer 66 may reserve a second light-transmitting area, that is, the electrochromic layer 66 does not cover the second light-transmitting area, for example, a through hole with a corresponding shape and size may be formed in the electrochromic layer 66 corresponding to the second light-transmitting area, so that the second light-transmitting area exposes the electrochromic layer 66.

In an embodiment of the present application, the rear cover assembly 60 or the decoration 100 may further include an anti-glare layer 67, where the anti-glare layer 67 is disposed on a surface of the electrochromic layer 66 facing away from the color layer 65, and the anti-glare layer 67 is used to improve a visible angle of the rear cover 61 and the light-emitting optical module, reduce interference of ambient light on the light-entering optical module, and reduce reflection of light from the rear cover 61. It is understood that the antiglare layer 67 may be adhered and fixed to the surface of the electrochromic layer 66 facing away from the color layer 65 by any one of an optical adhesive layer, an adhesive layer, and a double-sided adhesive layer.

In other embodiments of the present application, the electrochromic layer 66 may be omitted in order to reduce the overall thickness of the back cover assembly 60 or the decorative piece 100, i.e., the anti-glare layer 67 is disposed on the surface of the color layer 65 facing away from the back cover 61. The antiglare layer 67 may be bonded and fixed to the surface of the color layer 65 facing away from the rear cover 61 by any one of an optical adhesive layer, an adhesive layer, and a double-sided adhesive layer.

The back cover assembly 60 or the trim 100 further includes an anti-fingerprint (AF) layer 68, and the anti-fingerprint layer 68 is disposed on a first surface 611 of the back cover 61 (i.e., an outer surface of the back cover 61) and covers the first protective layer 63 and the second protective layer 64. The fingerprint resistant layer 68 serves to protect the back cover assembly 60 or the decoration 100 from the external environment, and also may improve the appearance characteristics and visual effect of the back cover assembly 60 or the decoration 100. The principle of the fingerprint-resistant layer is to disperse the textures of the fingerprints, so that the fingerprints on the rear cover assembly 60 or the decoration 100 cannot be displayed to play a certain antibacterial role, and the surface of an object after being subjected to fingerprint-resistant coating treatment can be good in hydrophobicity and oleophobicity, so that the fingerprint-resistant film can also reduce the adhesion of various stains, prevent water and oil, easily remove the adhered stains, and can continue to play a role after being wiped by tissues and the like due to the high-adhesion film, and meanwhile, the film layer cannot be peeled off, so that the appearance cannot be deteriorated. It is understood that the anti-fingerprint layer 68 may be adhered and fixed to the first surface 611 of the rear cover 61 by any one of an optical adhesive layer, an adhesive layer, and a double-sided adhesive layer.

In an exemplary embodiment, the thickness of the anti-fingerprint layer 68 is 80nm to 120nm, for example, 80nm, 82nm, 85nm, 88nm, 90nm, 95nm, 98nm, 100nm, 105nm, 108nm, 110nm, 115nm, 118nm, 120nm, or other values, which the present application is not particularly limited to.

In the embodiment of the present application, the rear cover assembly 60 or the decoration 100 further includes a light-reducing layer 69, and the light-reducing layer 69 is adhered to the second surface 612 of the rear cover 61 (i.e. the inner surface of the rear cover 61), and corresponds to the position of the optical device. The light-reducing layer 69 is used to reduce or eliminate reflected light from the light-emitting surface of the optical device and increase the transmittance and light transmission of light to reduce or eliminate stray light. In an exemplary embodiment, the light reduction layer 69 may be an Anti-reflective (AR) film that increases the transmittance and the light transmission amount of light by reducing the surface reflection of the light. Therefore, by performing the anti-reflection treatment on the second surface 612 of the rear cover 61 corresponding to the optical device, the light transmittance of the optical device can be improved, and the light reflectance can be reduced for the purpose of anti-reflection.

In the embodiment of the present application, the light-reducing layer 69 may be directly formed on the second surface 612 of the rear cover 61 by a vacuum evaporation coating method, and corresponds to the position of the optical device. Specifically, an antireflection film is formed by performing an antireflection coating treatment at a position corresponding to the optical device on the inner surface (i.e., the second surface 612) of the rear cover 61.

In an exemplary embodiment, the thickness of the light reduction layer 69 may be 650nm to 750nm, for example, 650nm, 670nm, 680nm, 700nm, 710nm, 730nm, 740nm, 750nm, or other values, which is not particularly limited by the present application.

The light-transmitting area includes a first surface 611 far away from the electronic device body and a second surface 612 near the electronic device body, the first surface 611 is provided with a protective layer, the protective layer at least corresponds to the optical module, and the mohs hardness of the protective layer is greater than that of the rear cover 61. Therefore, the rear cover 61 or the decoration 100 of the rear cover assembly 60 of the present application adopts a transparent design at least partially, and solves the problem of the related art that the rear cover of the housing assembly lacks in appearance ornamental value and integrity by providing the protection layer on the first surface 611 (i.e., the outer surface) of the light-transmitting area corresponding to the optical module, and the mohs' hardness of the protection layer is greater than that of the housing body, thereby improving the scratch and scratch resistance effect of the rear cover 61.

Moreover, the rear cover assembly 60 not only increases the protection of the optical module and improves the integrity and the aesthetic property of the electronic device 1 by providing the corresponding protection layer on the outer surface (i.e. the first surface 611) of the rear cover 61 or the position of the decoration 100 corresponding to the optical module, but also can enable the rear cover 61 to have a general Deco function by thickening the outer side of the rear cover 61 or providing a certain radian on the outer surface of the rear cover 61, so that the rear cover assembly 60 or the decoration 100 does not need a decorative ring (CAM Deco) design, so that the rear cover 61 has a simple structure, a simpler appearance, a higher appearance integrity and further improves the appearance integrity of the electronic device 1.

In addition, compared with the light-emitting optical module in the related art, which requires an additional lampshade to reduce the brightness of the lamp beads, the rear cover assembly 60 of the embodiment of the application performs the coating/polishing treatment on the inner surface (i.e., the second surface 612) of the rear cover 61, and the rear cover with the light-transmitting effect is integrally designed to achieve the effect of reducing the brightness of the lamp beads, thereby reducing the manufacturing cost.

In an exemplary embodiment, the brightness enhancement layer 72 may be a brightness enhancement film.

In the embodiment of the present application, the light enhancement layer 72 mainly uses Polycarbonate (PC), polyvinyl alcohol (PVA) or PET (polyester) as a base film, and the surface prepares a prism pattern or a micro-nano optical structure by a precision molding technique.

The color layer 65 is used to adjust the color and brightness of the image displayed by the optics. Therefore, the color layer 65 may be color-tunable, and by attaching the color layer 65 to the second surface 612 (i.e., the inner surface) of the rear cover 61 and making the color layer 65 correspond to the position of the optical device, the color and brightness of the image displayed by the optical device may be adjusted, so that the optical device may display a preset image color and brightness. Moreover, the screen brightness and the color of the optical device are adjusted by arranging the color layer 65, so that the optical device does not need to add a dot matrix screen cover on the rear cover 61, the structure of the product is simpler, the appearance is simpler, and the appearance integrity, the aesthetic property and the appearance display effect of the electronic equipment 1 are further improved.

The rear cover assembly 60 or the decoration 100 is used for transmitting light rays of the optical module and forming a preset display effect and display brightness. For example, the back cover assembly 60 or the decoration 100 may be used to reduce the brightness of light transmitted through the back cover assembly 60 or the decoration 100 when the optical device is in operation, and/or to reduce the reflection and scattering of light to achieve a predetermined brightness when the optical device is in operation, and/or to uniformly display light transmitted through the back cover assembly 60 or the decoration 100 when the optical device is in operation, and/or to adjust the color of light transmitted through the back cover assembly 60 or the decoration 100 when the optical device is in operation.
