[0002] Existing electronic devices are developing faster and faster. As users' demands for user experience gradually increase, electronic devices are gradually becoming lighter and thinner.

[0003] An optical assembly is arranged around the camera of an electronic device, and the optical assembly includes a lampshade and optical devices such as a color temperature sensor and a flash located inside the lampshade. As electronic devices become thinner and lighter, the storage space inside the electronic device is reduced, and the thickness of the optical assembly needs to be reduced. The reduction in the thickness of the optical assembly reduces the storage space of the lampshade accordingly, while the size of optical devices such as the color temperature sensor and the flash is large, which may cause the above optical devices to be unable to be installed. Summary of the invention

[0047] The technical solutions in the embodiments of the present application will be described clearly below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, other embodiments obtained by ordinary technicians in this field without making creative work all belong to the protection scope of the present application.

[0048] In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0049] In addition, in the present application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to the changes in the orientation of the components in the drawings.

[0050] The electronic device described in the embodiments of the present application includes but is not limited to a mobile phone, a watch, a notebook computer, a tablet computer, a laptop computer, a personal digital assistant or a wearable device, etc. The following description is made by taking the electronic device as a mobile phone.

[0051] Figure 1 is a first structural schematic diagram of a mobile phone 10; Figure 2 It is a second structural schematic diagram of the mobile phone 10.

[0052] like Figure 1 and Figure 2 As shown, the mobile phone 10 may include a screen 11, a body 12 and a rear cover 13, and the screen 11, the body 12 and the rear cover 13 are buckled together in sequence.

[0053] A camera module 14 is disposed on the body 12 , and a camera lens 15 is disposed on the rear shell 13 . The camera lens 15 is fixed to the camera module 14 via a camera decorative piece (not shown in the figure).

[0054] The camera lens 15 can be made of glass, and the camera lens 15 includes multiple visual areas. The number of visual areas is the same as the number of lenses of the camera module 14, and the positions are corresponding, so that each lens of the camera module 14 can be exposed from each visual area of ​​the camera lens 15, so that the camera module 14 can capture images using each lens.

[0055] A flash assembly 16 is disposed around the camera module 14 . Similarly, the camera lens 15 includes a visible area that allows the flash assembly 16 to be exposed.

[0056] It should be noted that the mobile phone 10 also includes components such as a circuit board, a battery and a speaker assembly, which are not listed here one by one.

[0057] To facilitate explanation of the positions of various components in the mobile phone 10, the embodiment of the present application exemplarily establishes a three-dimensional coordinate system based on the mobile phone 10, wherein the x-axis direction is the width direction of the mobile phone 10, the y-axis direction is the length direction of the mobile phone 10, and the z-axis direction is the thickness direction of the mobile phone 10.

[0058] Figure 3 yes Figure 2 Schematic diagram of the structure of the AA section. Figure 3 Only the camera lens 15 and the flash assembly 16 and their related structures are shown, and the remaining structures of the mobile phone 10 are not shown.

[0059] like Figure 3 As shown, the flash assembly 16 includes a flash cover 161, and the flash cover 161 includes a first cavity 162 and a second cavity 163. The first cavity 162 is recessed from one surface of the flash cover 161 to a certain depth inside the flash cover 161, and the second cavity 163 is recessed from the same surface of the flash cover 161 to a certain depth inside the flash cover 161. The depth corresponding to the first cavity 162 and the depth corresponding to the second cavity 163 can be the same or different.

[0060] The flash assembly 16 further includes a flexible plate 17, which is located at the opening side of the flash cover 161. The flexible plate 17 is provided with optical devices such as a light flicker detection module 171, a color temperature module 172, and a flash group 173. The light flicker detection module 171 and the color temperature module 172 are located in the first cavity 162, and the flash group 173 is located in the second cavity 163.

[0061] The camera lens 15 is located on the closed side of the flash lamp cover 161, the closed side is opposite to the open side, and the camera lens 15 and the flexible plate 17 are located on opposite sides of the lamp cover 161. The camera lens 15 includes a first visible area 151 and a second visible area 152, the first visible area 151 corresponds to the first cavity 162, and the second visible area 152 corresponds to the second cavity 163. In this way, external light enters the first cavity 162 from the first visible area 151 through the flash lamp cover 161 at the corresponding position, and the light emitted by the flash lamp group 173 in the second cavity 163 is transmitted through the flash lamp cover 161 at the corresponding position and emitted from the second visible area 152.

[0062] The first cavity 162 includes a light-homogenizing film 164 and an infrared cut-off film 165, which cover the light flicker detection module 171 and the color temperature module 172 and are located on the light-incoming path of the first cavity 162. The light-homogenizing film 164 is used to evenly distribute the light coming in through the flash lamp cover 161, and evenly disperse the light so that it can be received by the light flicker detection module 171 and the color temperature module 172 in the first cavity 162; the infrared cut-off film 165 is used to shield infrared light in the external light.

[0063] The surface of the flash cover 161 facing the camera lens 15 is provided with a Fresnel texture (not shown in the figure), which can not only focus light but also improve the appearance effect.

[0064] Due to the existence of the Fresnel texture and the thickness limitation of the flash cover 161, the thickness of the flash cover 161 cannot be too small, so that the thickness of the area of ​​the flash cover 161 with the Fresnel texture is equal to the overall thickness h of the light flicker detection module 171 and the color temperature module 172. 0 Reaching 0.5 mm or more, thereby increasing the thickness h of the flash lamp cover 161 161 .

[0065] When the mobile phone 10 is made thinner and lighter, the thickness of the mobile phone 10 is reduced, and the accommodation space is reduced, so that the thickness H between the camera lens 15 and the flexible board 17 is 0 To adapt to the thickness H 0 The thickness h of the flash lamp cover 161 is reduced. 161 The size of optical components such as the light flicker detection module 171, the color temperature module 172 and the flash lamp assembly 173 are relatively large, and a safety gap L is reserved between the color temperature module 172, which is relatively the largest, and the infrared cut-off film 165. 0 , the safety gap L 0 It can be about 0.15 mm. It can be seen that when the flash lamp cover 161 reduces the thickness h 161 When the optical device is installed, the above problem may occur.

[0066] In order to solve the above problems, the embodiments of the present application provide a lampshade assembly, an optical assembly and an electronic device 20, which can reduce the thickness of the flash lampshade 161 without affecting the installation of the optical device, so as to realize the lightness and thinness of the electronic device 20.

[0067] Figure 4 is a first structural schematic diagram of an electronic device 20 provided in an embodiment of the present application; Figure 5 is a second structural diagram of an electronic device 20 provided in an embodiment of the present application; Figure 6 : is an exploded view of the electronic device 20 provided in the embodiment of the present application. Figure 5 Relative to Figure 4 Structures such as the housing 22 , the lens 100 and the decorative element 701 are not shown.

[0068] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the electronic device 20 may include a display screen (not shown), a middle frame 21 and a housing 22, and the display screen, the middle frame 21 and the housing 22 are buckled together in sequence. The upper part of the middle frame 21 along the length direction (y-axis direction) is provided with a camera assembly 23, a lampshade assembly 24, an optical device assembly 600 and a bracket 704, etc., and a battery 25 is provided in the middle. Other devices may also be provided on the middle frame 21, which will not be described here.

[0069] The optical device assembly 600 may include a circuit board 601 and optical devices such as a light flicker detection sensor, a color temperature sensor, and a flash located on the circuit board 601. The lampshade assembly 24 and the optical device assembly 600 are combined together to form an optical assembly. The camera assembly 23 and the lampshade assembly 24 can maintain a relative positional relationship with the housing 22 through the decorative piece 701.

[0070] Figure 7 yes Figure 4 The first structural diagram of the BB section. Figure 7 Only the structures related to the lamp housing assembly 24 are shown.

[0071] Combination Figure 6 and Figure 7 As shown, in some embodiments, the lamp cover assembly 24 may include: a lens 100 , a lamp cover 200 and a light focusing layer 300 .

[0072] The lens 100 may include a first surface 100a and an exterior surface 100b, wherein the first surface 100a faces the inside of the electronic device 20, and the exterior surface 100b faces the outside of the electronic device 20, and the exterior surface 100b may be exposed from the housing 22 of the electronic device 20. For example, the lens 100 may be made of glass.

[0073] The lampshade 200 is located on one side of the lens 100. For example, the lampshade 200 may be made of materials such as polycarbonate (PC) or polymethyl methacrylate (PMMA), and the lampshade 200 is transparent.

[0074] The lampshade 200 is located on one side of the first surface 100a, and there is a gap between the lampshade 200 and the first surface 100a. The gap can not only prevent the lampshade 200 from colliding with the lens 100, but also facilitate the light transmission between the lens 100 and the lampshade 200. The gap can be about 0.1 mm.

[0075] Figure 8 This is a first structural schematic diagram of the lampshade 200 provided in an embodiment of the present application; Fig. 9 This is a second structural schematic diagram of the lampshade 200 provided in the embodiment of the present application.

[0076] Combination Figure 7 , Figure 8 and Fig. 9 As shown, in some embodiments, the lampshade 200 may include a second surface 200a and a third surface 200b which are opposite to each other. Along the z-axis direction, the second surface 200a is far away from the first surface 100a, and the third surface 200b is adjacent to the first surface 100a.

[0077] The lamp cover 200 may include a first through hole 201 opened toward the lens 100 , and the first through hole 201 is used to accommodate optical devices, such as a light flicker detection sensor and a color temperature sensor.

[0078] The first through hole 201 passes through the second surface 200a and the third surface 200b of the lampshade 200. The first through hole 201 can not only reduce the thickness of the lampshade 200, but also reduce the thickness of the lampshade 200. 200 , when the thickness is reduced, the first through hole 201 still has the space required to accommodate the optical device, thereby avoiding affecting the installation of the optical device. 200 It can be reduced by more than 0.2mm.

[0079] When reducing the thickness h of the lampshade 200 200 When the thickness of the area of ​​the lampshade 200 originally used for arranging the Fresnel texture is eliminated, the embodiment of the present application uses the focusing layer 300 to replace the Fresnel texture to maintain the original optical function of the lampshade assembly 24.

[0080] The light-gathering layer 300 is located between the lens 100 and the first through hole 201, and is used for gathering light. The thickness of the light-gathering layer 300 is less than the thickness of the area of ​​the lampshade 200 originally used for laying out the Fresnel texture. Thus, the overall thickness of the light-gathering layer 300 and the lampshade 200 is less than Figure 3 The thickness h of the flash cover 161 is shown 161 .

[0081] The lampshade assembly 24 provided in the embodiment of the present application can reduce the thickness of the lampshade 200 while ensuring the appearance effect. The lampshade 200 includes a first through hole 201 that can penetrate two opposite surfaces of the lampshade 200, and the Fresnel texture is replaced by the light-gathering layer 300, and the light-gathering layer 300 provides the light-gathering function. In this way, when the thickness of the lampshade 300 is reduced, the first through hole 201 still has the space required to accommodate the optical device, avoiding affecting the installation of the optical device, and maintaining the original optical function of the lampshade assembly 24. Furthermore, the thickness h of the lampshade assembly 24 can be made 24 The internal space occupied by the electronic device 20 can be reduced, thereby making the electronic device 20 lighter and thinner.

[0082] See again Figure 7 and Fig. 9 In some embodiments, the lampshade assembly 24 may further include: an infrared cut-off layer 400 and a light-homogenizing layer 500 .

[0083] The infrared cut-off layer 400 is located between the light-collecting layer 300 and the first through hole 201, and covers the first through hole 201. The infrared cut-off layer 400 may be an infrared cut-off film, and the infrared cut-off layer 400 is used to cut off infrared light in the external light to eliminate the influence of infrared light on imaging, and maintain high transmittance of visible light, so that imaging is more in line with the best feeling of human eyes.

[0084] The light-homogenizing layer 500 is located between the light-collecting layer 300 and the infrared cut-off layer 400. The light-homogenizing layer 500 may be a light-homogenizing film, and the light-homogenizing layer 500 is used to correct the light into a uniform surface light source to achieve an optical diffusion effect and improve the uniformity of light reception. Exemplarily, the light-homogenizing layer 500 may evenly disperse the incident light from the outside so that it can be received by the optical device in the first through hole 201, thereby improving the light reception effect.

[0085] In some embodiments, the third surface 200b of the lampshade 200 may include an adhesive area 200c ( Fig. 9 The adhesive area 200c is located at the edge of the first through hole 201.

[0086] The infrared cut-off layer 400 can be attached to the adhesive area 200c of the third surface 200b of the lampshade 200 through an adhesive layer, and cover the first through hole 201; the light-distributing layer 500 can be attached to the surface of the infrared cut-off layer 400 away from the first through hole 201 through an adhesive layer. The light-distributing layer 500 and the infrared cut-off layer 400 can have the same size and be larger than the size of the first through hole 201. In this way, the light-distributing layer 500 and the infrared cut-off layer 400 can both cover the first through hole 201, so that the external light can be processed by the light-distributing layer 500 and the infrared cut-off layer 400, and then received by the optical device in the first through hole 201, thereby improving the light receiving effect.

[0087] See again Figure 7 In some embodiments, the light-collecting layer 300 may be located on the surface of the light-homogenizing layer 500 .

[0088] Exemplarily, the light-focusing layer 300 can be adhered to the surface of the light-distributing layer 500 facing the lens 100 through an adhesive layer. The light-focusing layer 300 can also be formed on the surface of the light-distributing layer 500 facing the lens 100 through a transfer process. The specific details can be found in the following content and are not repeated here.

[0089] There is a first distance L between the light focusing layer 300 and the first surface 100a of the lens 100 1 , the first surface 100a faces the lampshade 200. The first distance L 1 To prevent the light-collecting layer 300 from colliding with the lens 100, for example, the first distance L 1 It can be about 0.1mm.

[0090] Since the thickness h of the lampshade 200 200 The total thickness h of the light-collecting layer 300, the infrared cut-off layer 400 and the light-homogenizing layer 500 is reduced. 1 The thickness h 1 Less than Figure 3 The thickness of the area of ​​the flash lamp cover 161 provided with the Fresnel texture is equal to the overall thickness of the light flicker detection module 171 and the color temperature module 172. 0 The thickness of the lampshade 200 is h 200 If the thickness is reduced by more than 0.2 mm, then the thickness h 1 Reduce by more than 0.2mm.

[0091] For the convenience of describing the direction, the first direction is defined as being perpendicular to the axial direction of the first through hole 201. The axial direction of the first through hole 201 is the z-axis direction, and the first direction is the y-axis direction.

[0092] In some embodiments, the first through hole 201 may include a first side edge 2011 and a second side edge 2012, wherein the first side edge 2011 is opposite to the second side edge 2012. The first side edge 2011 is located along the first direction at a region of the lampshade 200 on one side for forming the first through hole 201, and the second side edge 2012 is located along the first direction at a region of the lampshade 200 on the opposite side for forming the first through hole 201.

[0093] Along the first direction, the light collecting layer 300 extends from the first side edge 2011 of the first through hole 201 to the second side edge 2012, and the light collecting layer 300 covers the first through hole 201. In this way, the light collecting layer 300 can be used to achieve a light collecting effect on the path of external light entering the first through hole 201.

[0095] like Fig.10 As shown, in some embodiments, the light focusing layer 300 may be located on the first surface 100 a of the lens 100 .

[0096] Exemplarily, the light-gathering layer 300 can be adhered to the first surface 100a of the lens 100 by an adhesive layer, and the light-gathering layer 300 can also be formed on the first surface 100a of the lens 100 by a transfer process. The specific details can be found in the following content and are not repeated here.

[0097] There may be a second distance L between the light-collecting layer 300 and the light-distributing layer 500. 2 The second distance L 2 To prevent the light-collecting layer 300 from colliding with the light-distributing layer 500, for example, the second distance L 2 It can be about 0.1mm.

[0098] Along the first direction, the light collecting layer 300 extends from the first side edge 2011 of the first through hole 201 to the second side edge 2012, and the light collecting layer 300 covers the first through hole 201. In this way, the light collecting layer 300 can be used to achieve a light collecting effect on the path of external light entering the first through hole 201.

[0099] Fig.11 yes Fig. 9 The first structural diagram of the CC section.

[0100] Combination Figure 7 , Fig.10 and Fig.11 As shown, in some embodiments, the lamp cover 200 may further include a receiving hole 202, and the receiving hole 202 is used to receive an optical device, such as a flash.

[0101] Along the first direction, the receiving hole 202 is located at one side of the first through hole 201 , and the axial direction of the receiving hole 202 is parallel to the axial direction of the first through hole 201 .

[0102] There is a gap between the receiving hole 202 and the first through hole 201, which can physically isolate the optical device received in the receiving hole 202 from the optical device received in the first through hole 201, thereby reducing the mutual influence of the optical devices. For example, the influence of the light of the flash lamp received in the receiving hole 202 on the light detected by the light flicker detection sensor and the color temperature sensor received in the first through hole 201 can be avoided.

[0103] In some embodiments, the receiving hole 202 may be a blind hole. Along the axial direction (z-axis direction) of the receiving hole 202, the receiving hole 202 is recessed from the second surface 200a of the lampshade 200 to the inside of the lampshade 200 by a first depth, and the first depth is positively correlated with the thickness of the flash lamp.

[0104] The lampshade 200 further includes a sealing portion 203 for forming the receiving hole 202 in the form of a blind hole, and the sealing portion 203 is adjacent to the first surface 100 a.

[0105] There is an assembly gap between the ends of the infrared cutoff layer 400 and the light homogenizing layer 500 facing the receiving hole 202 and the sealing portion 203, and the assembly gap prevents the infrared cutoff layer 400 and the light homogenizing layer 500 from colliding with the sealing portion 203. Fig. 9 The structure of the semi-circular adhesive area 200c shown can also prevent the adhesive layer from spreading onto the sealing portion 203. Therefore, it is possible to avoid blocking the receiving hole 202 and prevent the optical device contained in the receiving hole 202 from playing its role. Exemplarily, the assembly gap is used to prevent the infrared cutoff layer 400 and the light homogenizing layer 500 from blocking the emitted light of the flash lamp.

[0106] Along the direction from the second surface 200a to the third surface 200b of the lampshade 200, the surface of the sealing portion 203 facing the lens 100 protrudes from the surface of the first through hole 201 facing the lens 100. In this way, the third surface 200b of the lampshade 200 can form a stepped structure and form a thickness difference h 200-1 Using this thickness difference h 200-1 It is convenient to install the light collecting layer 300, the infrared cut-off layer 400 and the light homogenizing layer 500, so that the surface of the light collecting layer 300 is lower than or flush with the surface of the sealing portion 203. In this way, it is possible to avoid increasing the thickness h of the lampshade 200. 200 .

[0107] See again Figure 7 , Fig. 9 and Fig.11In some embodiments, the sealing portion 203 may include a first Fresnel texture surface 2031. The first Fresnel texture surface 2031 includes equidistant tooth-shaped textures, which can be viewed as concentric circles from small to large from a top view, and its texture is designed based on light interference and perturbation, relative sensitivity, and receiving angle requirements. The first Fresnel texture surface 2031 can focus light and provide a concentric circle appearance effect.

[0108] The first Fresnel texture surface 2031 may be located on a surface of the sealing portion 203 facing the receiving hole 202 , or on a surface of the sealing portion 203 facing the first surface 100 a .

[0109] Fig.12 This is a first top view of the lampshade 200 and the light-collecting layer 300 provided in the embodiment of the present application.

[0110] Combination Figure 7 , Fig.10 and Fig.12 As shown, in some embodiments, the light focusing layer 300 may be a Fresnel film 301. The Fresnel film 301 may be very thin to reduce the thickness of the lampshade 200.

[0111] like Figure 7 As shown, the Fresnel film 301 may be located on the surface of the light-distributing layer 500. For example, the Fresnel film 301 may be attached to the surface of the light-distributing layer 500 facing the lens 100 through an adhesive layer. Fig.10 As shown, the Fresnel film 301 may be located on the first surface 100a of the lens 100. Exemplarily, the Fresnel film 301 may be attached to the first surface 100a of the lens 100 via an adhesive layer.

[0112] Along the first direction, the Fresnel film 301 extends from the first side edge 2011 of the first through hole 201 to the second side edge 2012, and the Fresnel film 301 covers the first through hole 201. In this way, the Fresnel film 301 can be used to achieve a focusing effect on the path of external light entering the first through hole 201.

[0113] The Fresnel film 301 may include a second Fresnel texture surface 3011. The structural characteristics and functions of the second Fresnel texture surface 3011 may refer to the first Fresnel texture surface 2031, and will not be described in detail here.

[0114] No matter the Fresnel film 301 is located on the surface of the light homogenizing layer 500 or on the first surface 100a of the lens 100, the second Fresnel texture surface 3011 can be located on the surface of the Fresnel film 301 facing the first through hole 201, or on the surface of the Fresnel film 301 facing the first surface 100a.

[0115] The second Fresnel texture surface 3011 corresponds to the first through hole 201, and the first Fresnel texture surface 2031 corresponds to the receiving hole 202. Thus, while achieving light transmission, the surface of the lampshade 200 facing the exterior can be regarded as two groups of concentric circle textures from small to large.

[0116] Fig.13 It is a top view of the lampshade assembly 24 provided in the embodiment of the present application.

[0117] Combination Figure 7 , Fig.12 and Fig.13 As shown, in some embodiments, the lens 100 may include a first visible light-transmitting area 101 and a second visible light-transmitting area 102 .

[0118] The first visible light-transmitting area 101 corresponds to the first through hole 201 and the second Fresnel texture surface 3011. External light enters from the first visible light-transmitting area 101 and passes through the Fresnel film 301. It is focused by the second Fresnel texture surface 3011 and enters the lampshade 200 at the corresponding position. It then enters the first through hole 201 after being processed by the light-homogenizing layer 500 and the infrared cutoff layer 400, and is received by optical devices such as the light flicker detection sensor and the color temperature sensor in the first through hole 201.

[0119] The second visible light-transmitting area 102 corresponds to the receiving hole 202 and the first Fresnel texture surface 2031 . The light emitted by the flash lamp in the receiving hole 202 passes through the lampshade 200 at the corresponding position and is focused by the first Fresnel texture surface 2031 before being emitted from the second visible light-transmitting area 102 .

[0120] In terms of appearance, the concentric circle textures of the first Fresnel texture surface 2031 and the second Fresnel texture surface 3011 can be exposed by utilizing the first visible light-transmitting area 101 and the second visible light-transmitting area 102 of the lens 100, thereby improving the appearance.

[0121] The shape boundary of the first visible light-transmitting area 101 can be determined according to the boundary of the first through hole 201. For example, the cross-sectional size of the first visible light-transmitting area 101 can be equal to or smaller than the cross-sectional size of the first through hole 201. The shape boundary of the second visible light-transmitting area 102 can be determined according to the boundary of the receiving hole 202. For example, the cross-sectional size of the second visible light-transmitting area 102 can be equal to or smaller than the cross-sectional size of the receiving hole 202. The cross-sectional size refers to the cross-sectional size along the y-axis direction.

[0122] The shape of the first visible light-transmitting area 101 and the shape of the second visible light-transmitting area 102 can be circular, square or other shapes to improve the appearance.

[0123] The sizes of the first through hole 201 and the receiving hole 202 may be the same or different. Similarly, the sizes of the first visible light-transmitting area 101 and the second visible light-transmitting area 102 may be the same or different.

[0124] If the first visible light-transmitting area 101 and the second visible light-transmitting area 102 have the same size, two groups of concentric circle textures of the same size are exposed from the appearance. If the first visible light-transmitting area 101 and the second visible light-transmitting area 102 have different sizes, two groups of concentric circle textures of different sizes are exposed from the appearance. In this way, different appearance effects can be provided.

[0125] Fig.14 It is a schematic diagram of the structure of the lens 100 provided in an embodiment of the present application.

[0126] like Fig.14 As shown, in some embodiments, the lens 100 may further include a shielding area 103. Exemplarily, the shielding area 103 may be obtained by performing a blackening process on the first surface 100a of the lens 100.

[0127] The shielding area 103 is located in the non-appearance area of ​​the lens 100 , and the shielding area 103 is located around the first visible light-transmitting area 101 and the second visible light-transmitting area 102 .

[0128] In this way, the crosstalk phenomenon of the optical devices in the first through hole 201 and the receiving hole 202 can be further avoided, and the mutual influence between the optical device received in the receiving hole 202 and the optical device received in the first through hole 201 can be avoided.

[0129] Fig.15 yes Fig. 9 The second structural diagram of the CC section.

[0130] like Fig.15 As shown, in some embodiments, the receiving hole 202 can be a through hole.

[0131] In this way, the receiving hole 202 serves as a second through hole, connecting the second surface 200a and the third surface 200b of the lampshade 200. The axial thickness h of the receiving hole 202 is 202 Equal to the thickness h of the lampshade 200 200 In this way, the thickness of the area of ​​the lampshade 200 originally used for arranging the Fresnel texture at the position corresponding to the flash lamp can be eliminated, so as to further reduce the thickness h of the lampshade 200. 200 .

[0132] In some embodiments, the axial thickness h of the receiving hole 202 in the form of a through hole is 202 can be greater than the axial thickness h of the first through hole 201 201In this way, the third surface 200b of the lampshade 200 can form a stepped structure and form a thickness difference. This thickness difference can facilitate the layout of the infrared cutoff layer 400 and the light-distributing layer 500, so that the surface of the light-distributing layer 500 is lower than or flush with the surface of the receiving hole 202. In this way, the thickness h of the lampshade 200 can be avoided from being increased. 200 .

[0133] In some embodiments, the axial thickness of the through-hole-shaped receiving hole 202 may also be equal to the axial thickness of the first through-hole 201, which is not shown in the figure. In this way, along the direction from the second surface 200a to the third surface 200b of the lampshade 200, the light-collecting layer 300, the infrared cut-off layer 400 and the light-homogenizing layer 500 all protrude from the surface of the receiving hole 202 facing the lens 100.

[0134] Fig.16 yes Figure 4 The third structural diagram of the BB section. Fig.16 Only the structures related to the lamp housing assembly 24 are shown.

[0135] like Fig.16 As shown, in some embodiments, when the light-gathering layer 300 is located on the surface of the light-distributing layer 500 and the receiving hole 202 is a blind hole, along the first direction, the light-gathering layer 300 can extend from the first side edge 2011 of the first through hole 201 to the third side edge 2021 of the receiving hole 202.

[0136] In some embodiments, when the light-collecting layer 300 adopts the Fresnel film 301, along the first direction, the Fresnel film 301 can extend from the first side edge 2011 of the first through hole 201 to the third side edge 2021 of the receiving hole 202. It can be understood that the Fresnel film 301 is continuously located on the surface of the light-distributing layer 500 facing the lens 100 and the surface of the sealing portion 203 facing the lens 100. In this way, the thickness of the sealing portion 203 used to form the first Fresnel texture surface 2031 can be eliminated, and the thickness h of the lampshade 200 can be further reduced. 200 .

[0137] Among them, along the first direction, the first side edge 2011 is away from the receiving hole 202, the third side edge 2021 is away from the first through hole 201, and the third side edge 2021 is located at a side area of ​​the lampshade 200 used to form the receiving hole 202 and away from the first through hole 201. In this way, the Fresnel film 301 can cover the first through hole 201 and the receiving hole 202 at the same time, and the Fresnel film 301 can be used to achieve the focusing effect of the external light entering the first through hole 201 and the focusing effect of the light emitted from the receiving hole 202 to the outside.

[0138] In some embodiments, the Fresnel film 301 is located on the surface of the light-homogenizing layer 500, the receiving hole 202 is a through hole, and the axial thickness h of the receiving hole 202 in the form of a through hole is 202 Greater than the axial thickness h of the first through hole 201 201 In the scenario (not shown in the figure), the Fresnel film 301 is continuously located on the surface of the light-homogenizing layer 500 facing the lens 100 and the surface of the receiving hole 202 facing the lens 100, and the Fresnel film 301 can simultaneously cover the first through hole 201 and the receiving hole 202. In this way, the thickness of the sealing portion 203 can be eliminated, the thickness of the lampshade 200 can be further reduced, and the Fresnel film 301 can be used to simultaneously meet the focusing requirements of the receiving hole 202.

[0139] The axial thickness h of the receiving hole 202 in the form of a through hole 202 Equal to the axial thickness h of the first through hole 201 201 In the scenario of the above, the local thickness of the Fresnel membrane 301 extending to the receiving hole 202 can be increased so that the Fresnel membrane 301 fits with the surface of the receiving hole 202 facing the lens 100, and the optical performance of the optical device at the receiving hole 202 is maintained. Alternatively, without affecting the optical performance of the optical device at the receiving hole 202, the Fresnel membrane 301 extending to the receiving hole 202 can be spaced from the surface of the receiving hole 202 facing the lens 100, so that the light can be better emitted.

[0140] Fig.17 yes Figure 4 The fourth structural diagram of the BB section. Fig.17 Only the structures related to the lamp housing assembly 24 are shown.

[0141] like Fig.17 As shown, in some embodiments, when the focusing layer 300 is located on the first surface 100a of the lens 100 and the receiving hole 202 is a blind hole, along the first direction, the focusing layer 300 can extend from the first side edge 2011 of the first through hole 201 to the third side edge 2021 of the receiving hole 202.

[0142] When the light-gathering layer 300 adopts the Fresnel film 301, the adhesive layer originally used for bonding between the Fresnel film 301 and the light-distributing layer 500 can be reduced by one layer. In this way, not only the thickness of the sealing part 203 used to form the first Fresnel texture surface 2031 can be eliminated, but also the thickness of the sealing part 203 corresponding to the adhesive layer can be further reduced, so that the surface of the light-distributing layer 500 facing the lens 100 is lower than or flush with the surface of the sealing part 203 facing the lens 100, so as to further reduce the thickness h of the lampshade 200. 200 .

[0143] It should be noted that the structural characteristics of the lampshade assembly 24 can be referred to Fig.16 The structural characteristics of the lampshade assembly 24 are not described in detail here.

[0144] Fig.18 This is a second top view of the lampshade 200 and the light-collecting layer 300 provided in the embodiment of the present application.

[0145] Combination Fig.16 , Fig.17 and Fig.18 As shown, in some embodiments, when the light-collecting layer 300 adopts the Fresnel film 301, the Fresnel film 301 may include a second Fresnel texture surface 3011, and the second Fresnel texture surface 3011 corresponds to the first through hole 201 and the receiving hole 202. In this way, from the perspective of appearance, the surface of the lampshade 200 facing the appearance can be regarded as a group of concentric circle textures from small to large.

[0146] Fig.19 yes Figure 4 The fifth structural diagram of the BB section. Fig.19 Only the structures related to the lamp housing assembly 24 are shown.

[0147] Combination Fig.12 and Fig.19 As shown, in some embodiments, the light-gathering layer 300 may be a tooth-shaped texture structure 302 , which may be formed by a transfer process, and the tooth-shaped texture structure 302 is used to provide a light-gathering function.

[0148] In some embodiments, the tooth-shaped texture structure 302 can be formed on the surface of the light-distributing layer 500 facing the lens 100 through a transfer process, and through the transfer process, the tooth-shaped texture structure 302 has a tooth-shaped surface 3021, and the tooth-shaped surface 3021 faces the first surface 100a of the lens 100. The transfer process can form an integrated structure of the tooth-shaped texture structure 302 and the light-distributing layer 500 to improve the combination stability of the tooth-shaped texture structure 302 and the lens 100.

[0149] There is a third distance L between the toothed surface 3021 and the first surface 100a of the lens 100 3 , the third distance L 3 To prevent the toothed texture structure 302 from colliding with the lens 100, the third distance L 3 It can be about 0.1mm.

The tooth-shaped texture 802 can be viewed as concentric circles from small to large from a top view. The two adjacent tooth-shaped textures 802 can be equidistant or unequally spaced, depending on the application scenario.

[0152] like Fig. 20 As shown in (b), in some embodiments, glue 804 is injected into the groove 803. The glue 804 is used to fill all the grooves 803 and cover all the tooth-shaped textures 802 to obtain an injection molded part. The glue 804 side of the injection molded part may have a flat surface 805.

[0153] like Fig. 20 As shown in (c), the injection molded part is turned over and glued to the surface of the light-distributing layer 500. For example, the flat surface 805 is glued to the surface of the light-distributing layer 500 facing the lens 100. The glue 804 is solidified by ultraviolet (UV) light curing. After that, the mold 801 is removed, so that the tooth-shaped texture structure 302 and the light-distributing layer 500 form an integral structure. In this way, the tooth-shaped texture structure 302 is formed on the surface of the light-distributing layer 500, and the tooth-shaped texture structure 302 has a tooth-shaped surface 3021, and the tooth-shaped surface 3021 faces the first surface 100a of the lens 100.

In this way, the tooth-shaped texture structure 302 can cover both the first through hole 201 and the receiving hole 202 at the same time, and the tooth-shaped texture structure 302 can be used to achieve the focusing effect of the external light entering the first through hole 201 and the focusing effect of the light emitted from the receiving hole 202 to the outside.

[0158] Fig.21 yes Figure 4 The sixth structural diagram of the BB section. Fig.21 Only the structures related to the lamp housing assembly 24 are shown.

[0159] like Fig.21 As shown, in some embodiments, the tooth-shaped texture structure 302 can be formed on the first surface 100a of the lens 100 by a transfer process, and the tooth-shaped texture structure 302 has a tooth-shaped surface 3021 through the transfer process, and the tooth-shaped surface 3021 faces the first through hole 201. The transfer process can make the tooth-shaped texture structure 302 and the lens 100 form an integral structure to improve the combination stability of the tooth-shaped texture structure 302 and the lens 100.

[0160] There is a fourth distance L between the toothed surface 3021 and the light-distributing layer 500. 4 , the fourth distance L 4 For preventing the tooth-shaped texture structure 302 from colliding with the light-distributing layer 500, the fourth distance L 4 It can be about 0.1mm.

[0161] When making this tooth-shaped texture structure 302, refer to Fig. 20 The injection molded parts are made according to the contents shown in (a) and (b). Fig. 20As shown in (c), the injection molded part is turned over and glued to the first surface 100a of the lens 100. For example, the flat surface 805 is glued to the first surface 100a of the lens 100. The glue 804 is solidified by ultraviolet (UV) light curing. After that, the mold 801 is removed, so that the tooth-shaped texture structure 302 and the lens 100 form an integral structure. In this way, the tooth-shaped texture structure 302 is formed on the first surface 100a, and the tooth-shaped texture structure 302 has a tooth-shaped surface 3021, and the tooth-shaped surface 3021 faces the first through hole 201.

In this way, the toothed texture structure 302 can be used to achieve a light focusing effect on the path of external light entering the first through hole 201.

[0163] From the appearance effect, the appearance effect of this lampshade assembly 24 can refer to Fig.12 and Fig.13 Content shown.

[0164] It should be noted that Fig.21 The structural characteristics, application and effect of the tooth-shaped texture structure 302 shown can be referred to Fig.10 The structural characteristics, applications and effects of the Fresnel membrane 301 shown are not described in detail here.

[0165] In some embodiments, along the first direction, the tooth-shaped texture structure 302 can extend from the first side edge 2011 of the first through hole 201 to the third side edge 2021 of the receiving hole 202.

Fig.17 and Fig.21 Corresponding content; From the appearance effect, the appearance effect of this lampshade assembly 24 can refer to Fig.18 The contents shown are not repeated here.

[0166] Fig. 22 yes Figure 4 The seventh structural diagram of the BB section. Fig. 22 Only the structures related to the lamp housing assembly 24 are shown.

[0167] like Fig. 22 As shown, in some embodiments, the infrared cutoff layer 400 and the light homogenizing layer 500 can be integrally formed. Exemplarily, the infrared cutoff medium is plated on one surface of the light homogenizing layer 500 to form a combined layer 501 .

[0168] In the scenario where the light-collecting layer 300 is a Fresnel film 301 and the receiving hole 202 is a blind hole, the combined layer 501 is attached to the adhesive area 200c of the third surface 200b of the lampshade 200 through the adhesive layer, and covers the first through hole 201. During the attachment, the surface of the combined layer 501 coated with the infrared cut-off medium faces the first through hole 201, and the light-homogenizing layer 500 faces the lens 100.

[0169] In this way, the infrared cut-off layer 400 and the light homogenizing layer 500 are integrally formed, and the thickness difference between the sealing portion 203 corresponding to the receiving hole 202 and the first through hole 201 can be reduced, so as to further reduce the thickness of the lampshade 200, and then reduce the thickness of the lampshade assembly 24. In addition, the axial thickness of the first through hole 201 can be increased while the thickness of the lampshade 200 remains unchanged, so that the first through hole 201 has a larger space to accommodate a large-sized optical device.

[0176] Fig.23 It is a first structural schematic diagram of the optical component 26 provided in an embodiment of the present application.

[0177] Combination Figure 6 and Fig.23 As shown, in some embodiments, the optical assembly 26 may include: the lamp cover assembly 24 and the optical device assembly 600 provided in any of the aforementioned embodiments.

[0178] The optical device assembly 600 may include a circuit board 601 , and optical devices such as a light flicker detection sensor 602 , a color temperature sensor 603 , and a flash 604 located on the circuit board 601 .

[0179] The circuit board 601 may be a printed circuit board (PCB) or a flexible printed circuit (FPC). The circuit board 601 is electrically connected to the optical devices such as the light flicker detection sensor 602, the color temperature sensor 603 and the flash light 604 arranged thereon, so as to enable the optical devices such as the light flicker detection sensor 602, the color temperature sensor 603 and the flash light 604 to realize their own functions.

[0180] The light flicker detection sensor 602 is used to detect flickering of external light / ambient light. When flickering is detected in the external light, the light flicker detection sensor 602 sends the detection data to the processor of the electronic device, and eliminates the flickering phenomenon through processing to improve the image quality collected by the camera assembly 23. Exemplarily, the light flicker detection sensor 602 can be a Flicker sensor.

[0181] The color temperature sensor 603 is used to detect the color temperature of the environment when taking pictures, so that the colors of the pictures taken are more accurate. It can also automatically identify different shooting scenes through artificial intelligence (AI) and optimize the captured images in a targeted manner, bringing more outstanding photo effects.

[0182] The flash 604 is a fill light device, which can ensure that the picture is clear and bright in dim conditions. When shooting outdoors, the flash 604 can also be used as an auxiliary light source to emphasize the color tone of the object being photographed.

There is a gap L between the circuit board 601 and the lampshade 200. 5 , to prevent the circuit board 601 from colliding with the lampshade 200. 5 It can be around 0.4-0.5mm.

[0184] The light flicker detection sensor 602 and the color temperature sensor 603 are located in the first through hole 201, and the flash lamp 604 is located in the receiving hole 202 of the lampshade assembly. In this way, the light flicker detection sensor 602 and the color temperature sensor 603 can be accommodated by the first through hole 201, and the flash lamp 604 can be accommodated by the receiving hole 202.

[0185] Since the thickness of the color temperature sensor 603 is greater than that of other optical devices, a first gap L is provided between the color temperature sensor 603 and the infrared cut-off layer 400 to avoid collision. 6 For example, the first gap L6 It can be about 0.15mm.

[0186] Thus, the thickness h of the lampshade assembly 24 is 24 In the case of reducing the thickness, the first through hole 201 is used to accommodate the light flicker detection sensor 602 and the color temperature sensor 603, and the accommodating hole 202 is used to accommodate the flash 604, so that the installation of optical devices such as the light flicker detection sensor 602, the color temperature sensor 603 and the flash 604 can be ensured. At the same time, the thickness h of the optical assembly 26 can also be reduced. 26 , the thickness h of the optical component 26 26 Less than Figure 3 The thickness H between the camera lens 15 and the flexible plate 17 is shown as 0 .

[0188] Combination Figure 6 and Fig.24 As shown, in some embodiments, when fixing the optical assembly 26 , the lens 100 and the lamp cover 200 can be fixed by the decorative piece 701 .

[0189] The lampshade 200 may include a first extension portion 204, which extends from the center of the lampshade 200 to the outside. The thickness of the first extension portion 204 is less than the thickness of the lampshade 200, the lower surface of the first extension portion 204 is flush with the second surface 200a, and the upper surface of the first extension portion 204 forms a step structure with the third surface 200b. In the first direction, the "lower surface" described herein is away from the lens 100, and the "upper surface" described herein is close to the lens 100, and the same applies below.

[0190] The decorative element 701 may include a second extension portion 7011. The thickness of the second extension portion 7011 is less than that of the decorative element 701, the upper surface of the second extension portion 7011 is flush with the surface of the decorative element 701 adjacent to the lens 100, and the lower surface of the second extension portion 7011 and the lower surface of the decorative element 701 form an inverted step structure.

[0191] Exemplarily, the lens 100 is bonded to the upper surface of the decorative member 701 and the second extension 7011 through the first adhesive layer 702, and the first extension 204 of the lampshade 200 is bonded to the lower surface of the second extension 7011 of the decorative member 701 through the second adhesive layer 703. The first extension 204 and the second extension 7011 form a snap-fit ​​structure.

[0192] The surface of the circuit board 601 facing the lampshade 200 fits with the lower surface of the main body of the decorative component 701 , and the surface of the circuit board 601 away from the lampshade 200 can be fixed by a bracket 704 , and the bracket 704 is fixed on the middle frame 21 of the electronic device 20 .

The lens 100 of the lampshade assembly 24 includes a plurality of visible light-transmitting areas, each of which may correspond to the position of the camera assembly 23 and the lampshade assembly 24. The lens 100 may be embedded in the housing 22 and exposed along the exterior of the housing 22.

[0196] See again Figure 4 and Fig.24 , for the visible light-transmitting area corresponding to the lampshade assembly 24, for example, it may include a first visible light-transmitting area 101 and a second visible light-transmitting area 102. The position of the first visible light-transmitting area 101 corresponds to the first through hole 201 in the lampshade assembly 24, and the position of the second visible light-transmitting area 102 corresponds to the position of the receiving hole 202 in the lampshade assembly 24. The first through hole 201 and the receiving hole 202 are arranged along the first direction, and the corresponding first visible light-transmitting area 101 and the second visible light-transmitting area 102 are also arranged along the first direction. In this way, from the perspective of appearance, two groups / one group of equidistant concentric circles from small to large can be seen in the two visible light-transmitting areas arranged along the y-axis direction, thereby improving the appearance.
