First embodiment

The application provides a apron 20, please refer to fig. 2, apron 20 is including the first printing opacity portion 21 that is integral type structure, shading portion 22 and second printing opacity portion 23, shading portion 22 is located between first printing opacity and the second printing opacity portion 23, the luminousness of shading portion 22 is less than or equal to the default, first printing opacity portion 21 is arranged in relative with camera 30, in order to make outside light transmission go into camera 30, second printing opacity portion 23 is arranged in relative with flash 40, in order to transmit the light that flash 40 sent, shading portion 22 is arranged in shielding the light that flash 40 sent, in order to avoid penetrating into camera 30.

Alternatively, the cover 20 may be flat plate-shaped and include a thickness direction, which should be a direction in which external light or internal light is transmitted through the cover 20 perpendicularly, and a width direction, which should be a plane extending direction of the cover 20. The cover plate 20 may be made of plexiglass (Polymethyl methacrylate PMMA), which has good light transmission characteristics, is inexpensive, and is manufactured by a simple molding method. Of course, in other embodiments, the cover 20 may be made of other materials, and is not limited in particular.

The preset value of the light transmittance may be any value from 0% to 100%, or may be the original light transmittance of the raw material for manufacturing the cover plate 20, which is not particularly limited. Alternatively, the first light-transmitting portion 21 and the second light-transmitting portion 23 may be transparent structures with higher light transmittance, and the external light or the light emitted by the flash lamp 40 may be easily transmitted without shielding or absorbing the light, so that the light transmittance of the first light-transmitting portion 21 and the second light-transmitting portion 23 may be greater than or equal to a preset value, and may be 80% -100%. The light shielding portion 22 may be an opaque structure having a low light transmittance of color; alternatively, the light shielding portion 22 is black in color, and the light shielding portion 22 may block or absorb external light or light emitted from the flash 40, so that the light transmittance of the light shielding portion 22 may be less than a preset value, 0% -20%.

Alternatively, the first light-transmitting portion 21, the light-shielding portion 22, and the second light-transmitting portion 23 are connected, and the light-shielding portion 22 is located between the first light-transmitting portion 21 and the second light-transmitting portion 23. The projection of the first light transmitting portion 21 in the thickness direction should be opposed to the camera 30, and the projection of the second light transmitting portion 23 in the thickness direction should be opposed to the flash 40. Therefore, when the flash lamp 40 emits light and transmits the light into the second light-transmitting portion 23, the light is blocked by the light-shielding portion 22 and not transmitted to the first light-transmitting portion 21, so that the light channeling phenomenon during photographing is avoided.

In one embodiment, the cover 20 may be manufactured by manufacturing the light shielding portion 22 in a pre-designed mold by physical curing or chemical curing, and black or other dark pigment may be added to the raw material for manufacturing the light shielding portion 22, so that the light shielding portion 22 may have an opaque structure after molding. Then, after the light shielding portion 22 is cured, the first light transmitting portion 21 and the second light transmitting portion 23 may be fabricated in a mold. Wherein, the first light transmitting portion 21 and the second light transmitting portion 23 may be connected with the light shielding portion 22 due to the adhesive property of the polymer, thereby forming an integrated structure. Alternatively, the above-mentioned integrated structure should be a connection relationship between the first light-transmitting portion 21, the light-shielding portion 22 and the second light-transmitting portion 23, and there may be a connected interface between the first light-transmitting portion 21 and the light-shielding portion 22, but the three should be tightly connected.

By arranging the light shielding part 22 between the first light transmission part 21 and the second light transmission part 23, the light emitted by the flash lamp 40 can be prevented from entering the first light transmission part 21 after being transmitted to the second light transmission part 23 during photographing, and the light can be reflected or absorbed by the light shielding part 22, so that the light emitted by the flash lamp 40 cannot enter the camera 30, and the risk of light channeling during photographing is avoided; meanwhile, the first light-transmitting part 21, the light-shielding part 22 and the second light-transmitting part 23 are of an integrated structure, so that the connection tightness among the three parts can be improved, and the precision of the intelligent terminal 200 is improved.

In one embodiment, referring to fig. 2, the light shielding portion 22 includes a step surface 221, and the first light transmitting portion 21 is connected to the step surface 221. Alternatively, the step surface 221 is a side surface of the light shielding portion 22 in the thickness direction, the step surface 221 is closely connected to the first light transmitting portion 21, and the light shielding portion 22 should have at least a part protruding toward the first light transmitting portion 21, thereby forming a step. In the above embodiment, after the first light-transmitting portion 21 is manufactured, the interface at which the first light-transmitting portion 21 and the light-shielding surface are connected should be the step surface 221. The step surface 221 may be stepped in the thickness direction of the cap plate 20. Alternatively, the step size of the light shielding portion 22 on the side close to the flash 40 and the camera 30 may be larger, thereby facilitating the light shielding portion 22 to shield more light from the flash 40.

In one embodiment, referring to fig. 2, the area of the surface of the light shielding portion 22 facing the camera 30 is larger than the area of the surface facing away from the camera 30. Alternatively, the interface at which the light shielding portion 22 and the first light transmitting portion 21 are connected is not necessarily stepped, but may be a straight interface or a curved interface. Alternatively, in order to be able to block more light from the flash 40, the area of the light blocking portion 22 on the side surface close to the camera 30 should be larger, so that light transmitted along the side surface close to the camera can be blocked.

In one embodiment, referring to fig. 3, a surface of the second light-transmitting portion 23 facing away from the flash 40 and/or a surface facing the flash is formed with a texture layer 224. The texture layer 224 may be an uneven structure formed on the surface of the second light-transmitting portion 23 by polishing or etching, and may be a regular texture or frosted texture. Also, both of the opposite sides of the second light-transmitting portion 23 may be made as the textured layer 224, or this may be made on a separate side thereof. Optionally, the texture layer 224 is made to enhance the effect of the light emitted from the flash 40, so as to disperse the light, and make the light emitted from the flash 40 more uniform. In other embodiments, the texture layer 224 may be made of a material different from that of the cover 20, and then attached to the surface of the second transparent portion 23 by adhesion.

In one embodiment, the light shielding portion 22 includes a substrate and light shielding particles formed within the substrate. In manufacturing the light shielding portion 22, light shielding particles may be added to the raw material of the base material, the light shielding particles may be nanosilica, or the like, and the size of the light shielding particles may not be particularly limited. The purpose of the opacifying particles is to absorb or reflect light. When the number of the light shielding particles added in the substrate is large, the light shielding particles can change the preset value of the light transmittance of the light shielding part 22 to be smaller, so as to achieve the purpose of shielding light.

In one embodiment, the light transmittance of the substrate is the same as the light transmittance of the first light transmitting portion 21 and/or the second light transmitting portion. Alternatively, the cover plate 20 may be made of the same material as in the above embodiment, so the preset value of the light transmittance of the base material for making the light shielding portion 22 should be the same as the preset value of the light transmittance of the base material for making the first light transmitting portion 21.

In one embodiment, referring to fig. 3, a first light shielding layer 222 may be further disposed between the light shielding portion 22 and the first light transmitting portion 21, and/or a second light shielding layer 223 may be further disposed between the light shielding portion 22 and the second light transmitting portion 23. Alternatively, after the light shielding portion 22 is fabricated in the mold, black ink may be coated on the side wall of the light shielding portion 22, the black ink may further exert a light absorbing effect, and after the black ink is solidified, the first light transmitting portion 21 and the second light transmitting portion 23 may be continuously fabricated, thereby forming the first light shielding layer 222 between the first light transmitting portion 21 and the light shielding portion 22, or forming the second light shielding layer 223 between the second light transmitting portion 23 and the light shielding portion 22.

In one embodiment, the first light-shielding layer has a thickness of 10nm to 50nm; the first shading layer has a transmittance of 33% -43% under visible light. Alternatively, the thickness of the first light shielding layer 222 may be 15nm, 23nm, 32nm, 47nm, or the like.

In one embodiment, referring to fig. 4, a third light shielding layer 211 is formed on a surface of the first light transmitting portion 21 facing the camera 30. The third light shielding layer 211 may be black ink coated on the surface of the first light transmitting portion 21, and the black ink may have a good light absorbing effect. The third light shielding layer 211 should have a circular ring shape on the surface of the first light transmitting portion 21, and a central area of the third light shielding layer 211 should not be coated with black ink, so that the camera 30 can receive external light conveniently. Optionally, the third light shielding layer 211 is coated to absorb or reflect part of the strong light from the outside, so as to prevent the excessive external light received by the camera 30 from causing overexposure.

In one embodiment, referring to fig. 4, a fourth light shielding layer 231 is formed on a surface of the second light transmitting portion 23 facing the flash 40. The fourth light shielding layer 231 may be color ink coated on the surface of the second light transmitting portion 23, and the color ink may have a good light shielding effect. Of course, the specific color of the color ink is not limited, and alternatively, the light transmittance of the fourth light shielding layer 231 should be superior to that of the third light shielding layer 211. Alternatively, the fourth light shielding layer 231 should have a ring shape at the surface of the second light transmitting part 23, and the center area of the fourth light shielding layer 231 should be not coated with color ink, thereby facilitating the flash 40 to emit light to the outside. As can be appreciated, the purpose of the fourth light shielding layer 231 is to shield part of the light emitted from the flash 40, so as to prevent the light emitted from the flash 40 from being too strong during shooting, which would result in excessive exposure of the light received by the camera 30.

In one embodiment, referring to fig. 5, the light shielding portion 22 is annular and is wound around the outer periphery of the first light transmitting portion 21. Alternatively, the first light-transmitting portion 21 may be circular or polygonal, and the light-shielding portion 22 is wound around a side wall perpendicular to the width direction of the first light-transmitting portion 21. Because in the existing camera 30, the lenses for realizing the photographing function are all of a circular structure, the position of the end of the camera 30 for receiving light is also circular, and external light can enter the camera 30 in a surrounding manner. When the light shielding portion 22 is formed in a ring shape and is wound around the side wall of the first light transmitting portion 21, all light from the inside of the cover 20 and from the outer periphery of the first light transmitting portion 21 can be shielded. This prevents reflected light from the cover 20 from entering the camera 30 when the flash 40 emits light.

In one embodiment, referring to fig. 5, the second light-transmitting portion 23 is annular and is wound around the outer periphery of the light-shielding portion 22. On the basis of the embodiment, the number of the flash lamps 40 can be at least two, and the at least two flash lamps 40 are arranged in a ring array, so that the number of the flash lamps 40 can be increased, the photographing effect of the camera 30 in a dark light or night environment is enhanced, the light rays can be uniformly distributed by the flash lamps 40 arranged in the ring array, and the phenomenon of uneven imaging image quality during photographing is avoided. Alternatively, the flash 40 may be annular, and the flash 40 surrounds the camera 30 assembly, without limitation.

In one embodiment, when the number of cameras 30 is at least two, the first light-transmitting portion 21 should face at least two cameras 30. The central area of the third light shielding layer 211, which is not coated with black ink, should be the central area of each camera 30, alternatively, the area coated with black ink, in order to enable the cameras 30 to receive external light from the area, thereby imaging.

In an embodiment, referring to fig. 6, when at least two cameras 30 are arranged in a ring array, the first light-transmitting portion 21 faces at least two cameras 30, and a third light-shielding layer 211 is disposed at a position where the first light-transmitting portion 21 faces any one of the cameras 30. That is, there are at least two third light shielding layers 211, and the at least two third light shielding layers 211 are arranged in a ring array and are opposite to the camera 30.

In an embodiment, referring to fig. 6, when at least two flashlamps 40 are arranged in a ring array, at least two flashlamps 40 are opposite to the second light-transmitting portion 23, and a fourth light-shielding layer 231 is disposed at a position where the second light-transmitting portion 23 is opposite to any one of the flashlamps 40. That is, there are at least two fourth light shielding layers 231, and at least two fourth light shielding layers 231 are arranged in a ring array and are opposite to the flash lamp 40.

In one embodiment, referring to fig. 7, the first light-transmitting portion 21, the light-shielding portion 22 and the second light-transmitting portion 23 may be arranged in parallel. In other embodiments, the light shielding portion 22 may be connected to a portion of the sidewall of the first light transmitting portion 21, which is not particularly limited.

In an embodiment, referring to fig. 8, when at least two cameras 30 are arranged in an array, the first light-transmitting portion 21 faces at least two cameras 30, and a third light-shielding layer 211 is disposed at a position where the first light-transmitting portion 21 faces any one of the cameras 30. That is, there are at least two third light shielding layers 211, and at least two third light shielding layers 211 are arranged in an array and are opposite to the camera 30.

In one embodiment, referring to fig. 8, when at least two flashlamps 40 are arranged in an array, the second light-transmitting portion 23 faces at least two flashlamps 40, and a fourth light-shielding layer 231 is disposed at a position where the second light-transmitting portion 23 faces any one of the flashlamps 40. That is, there are at least two fourth light shielding layers 231, and at least two fourth light shielding layers 231 are arranged in an array and are opposite to the flash lamp 40.
