Technical Field

[0002] The embodiments of the present application relate to the technical field of electronic products, and in particular to an electronic device. Background Art

[0003] With the development of display technology, the application of under-screen functional devices such as front camera modules and light sensors is becoming more and more widespread. In order for the under-screen functional devices to perform their corresponding functions, the screen includes a non-display area, and the non-display area includes a light-transmitting area. This light-transmitting area can provide an optical path for the under-screen functional devices, allowing external light to pass through the screen to the under-screen functional devices. However, with the improvement of consumer demand, users have higher and higher functional requirements for electronic devices. The number and types of under-screen functional devices are increasing, resulting in an increasing area of ​​non-display area in the screen, affecting the screen-to-body ratio of electronic devices.

[0004] Summary of the Invention

[0005] The present application provides an electronic device that can reduce the area of ​​the non-display area in the screen and increase the screen-to-body ratio of the electronic device.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] In the first aspect, the present application provides an electronic device, which includes: a screen, a bracket structure, a front camera module and a light guide, the screen having a non-display area, the non-display area including a first light-transmitting area and a second light-transmitting area; the bracket structure includes a first bracket and a second bracket fixedly connected; the front camera module has a light incident surface, the front camera module is fixedly connected to the first bracket, and the light incident surface is opposite to the first light-transmitting area; the light guide has a light input surface and a first light output surface, the light guide is fixedly connected to the second bracket, and the light input surface is opposite to the second light-transmitting area.

[0008] The electronic device in the present application can be assembled to the housing of the electronic device as a whole by fixing the first bracket to the second bracket during assembly, thereby avoiding interference between the first bracket and the second bracket during assembly, and eliminating the need to reserve a clearance space between the first bracket and the second bracket. Thus, on the one hand, the distance between the light-entering surface of the light guide and the light-entering surface of the front camera module can be reduced, thereby reducing the distance between the center of the first light-transmitting area and the center of the second light-transmitting area, which is beneficial to reducing the area of ​​the non-display area in the screen, thereby facilitating an increase in the screen-to-body ratio of the electronic device. On the other hand, the size of the bracket structure in the first direction can be reduced, which can reduce structural redundancy and reduce the space occupied by the bracket structure, making the structure of the electronic device more compact, optimizing the structural layout of the electronic device, and facilitating a miniaturized design of the electronic device. In addition, the electronic device in this embodiment can achieve the appearance of a front dual camera even if only one front camera module is provided.

[0009] In a possible implementation of the first aspect, the first bracket and the second bracket are an integrated structural member. In this way, on the one hand, the connection reliability between the first bracket and the second bracket can be improved, and the processing technology of the bracket structure can be simplified, thereby reducing the cost of the bracket structure; on the other hand, the assembly error between the first bracket and the second bracket can be reduced, thereby facilitating the reduction of the assembly deviation between the light guide and the front camera module, and improving the assembly accuracy of the light guide and the front camera module, thereby improving the concentricity between the light incident surface of the front camera module and the first light transmission area, and the concentricity between the light incident surface of the light guide and the second light transmission area, reducing or eliminating the appearance eccentricity, and ensuring the amount of light entering the front camera module and the light guide while improving the appearance of the electronic device; on the other hand, the assembly steps of the electronic device can be reduced, the assembly difficulty can be reduced, and the assembly time can be saved, thereby improving the assembly efficiency and reducing the cost.

[0010] In one possible implementation of the first aspect, the first bracket includes a first side panel, the front camera module is located on a circumferentially inner side of the first side panel; the second bracket includes a second side panel, the light guide is located on a circumferentially inner side of the second side panel, and the second side panel is fixedly connected to the first side panel. This facilitates the fixed connection of the first bracket and the second bracket as a single unit, increases the connection area between the first bracket and the second bracket, and improves the reliability of the connection between the first bracket and the second bracket.

[0011] In one possible implementation of the first aspect, the outer wall surface of the first side panel is in contact with the outer wall surface of the second side panel. This reduces structural redundancy in the support structure, making it more compact. Furthermore, the support structure can be further reduced in size in the arrangement direction of the first and second supports, thereby further reducing the distance between the center of the first light-transmitting area and the center of the second light-transmitting area, reducing the non-display area of ​​the screen and increasing the screen-to-body ratio. Furthermore, the overall footprint of the support structure can be further reduced, facilitating assembly of the support structure, light guide, and front camera module within electronic devices with limited space, thereby facilitating miniaturization of the electronic device.

[0012] In one possible implementation of the first aspect, the first bracket includes a first top plate having a first through-hole defined therein; the first top plate is fixedly connected to the first side panel, and a first accommodating cavity is defined between the first top plate and the first side panel. The first accommodating cavity is connected to the first through-hole, and at least a portion of the front camera module is located within the first accommodating cavity, with a light incident surface exposed at the first through-hole. A specific structure of the first bracket is provided.

[0013] In one possible implementation of the first aspect, the first top plate may be made of metal. This reduces the thickness of the first top plate while improving the overall structural strength of the support structure and reducing its footprint. Furthermore, when the front camera module is a telephoto or zoom camera module, reducing the thickness of the first top plate also increases the focal length and zoom range of the front camera module, thereby improving the performance of the front camera module.

[0014] In one possible implementation of the first aspect, the first bracket includes a metal component, the metal component including a first top panel and a flange portion. The flange portion is connected to an edge of the first top panel and folded away from the first outer surface. The flange portion is fixedly connected to the first side panel. For example, the metal component and the first side panel may be integrally connected via a metal insert injection molding process. This simplifies the processing of the first top panel and the first side panel and improves the reliability of the connection between the first top panel and the first side panel.

[0015] In one possible implementation of the first aspect, the second bracket includes: a second top plate and a light-shielding tube, the second top plate being provided with a second through-hole, the second top plate being fixedly connected to the second side panel, and a second accommodating cavity being defined between the second top plate and the second side panel; the light-shielding tube being disposed around the second through-hole and projecting out of the second top plate in a direction away from the second side panel, the light-shielding tube including a first tube opening formed at an end of the light-shielding tube facing away from the second top plate; a portion of the light guide being located within the light-shielding tube, with a light-entering surface exposed at the first tube opening. A specific structure of the second bracket is provided.

[0016] In one possible implementation of the first aspect, the light guide includes a light guide column and a fixing seat, wherein at least a portion of the light guide column is located within a light-shielding tube, and a light-entering surface is formed on the light guide column; and the fixing seat is fixedly connected to the light guide column and is located at an end of the light guide column facing away from the light-entering surface, and the fixing seat is fixedly connected to the second top plate or the second side panel. A specific structure of the light guide is provided.

[0017] In one possible implementation of the first aspect, the fixing base includes a connecting portion and a skirt portion, wherein the connecting portion is fixedly connected to the light guide column; the skirt portion is fixedly connected to the circumferential outer side of the connecting portion, and the skirt portion is fixedly connected to the second bracket. This facilitates fixing the light guide to the second bracket.

[0018] In a possible implementation of the first aspect, the first bracket and the second bracket are arranged in a first direction; in the first direction, the maximum dimension of the fixing seat protruding from the light guide column in the direction away from the first bracket is a first dimension, and the maximum dimension of the fixing seat protruding from the light guide column in the direction close to the first bracket is a second dimension, and the first dimension is larger than the second dimension. In this way, the distance between the light guide and the first bracket can be reduced, and the distance between the light input surface of the light guide and the light input surface of the front camera module can be reduced. In this way, the distance between the center of the first light-transmitting area and the center of the second light-transmitting area can be further reduced, so as to achieve the purpose of reducing the area of ​​the non-display area and increasing the screen-to-body ratio of the screen. In addition, when the first bracket includes a metal part, setting the first dimension to be larger than the second dimension can also avoid interference between the fixing seat and the flange portion of the metal part.

[0019] In one possible implementation of the first aspect, the second top plate includes a second outer surface and a second inner surface that face each other, with the second outer surface facing the screen. A portion of the second inner surface is recessed toward the second outer surface to form a recessed groove, with the fixing seat accommodated within the recessed groove. This reduces the overlapped dimension of the second top plate and the fixing seat in the Z-axis direction, thereby reducing the space occupied by the second bracket and the light guide in the Z-axis direction, thereby facilitating a reduction in the thickness of the electronic device and achieving a thinner and lighter design.

[0020] In a possible implementation of the first aspect, an identification hole is provided on the second top plate, and the identification hole is spaced apart from the second through hole. In this way, the bracket module and the middle frame can be automatically assembled. On the one hand, the assembly accuracy of the bracket module and the middle frame can be improved, thereby improving the concentricity between the light incident surface of the front camera module and the first light-transmitting area, and the concentricity between the light incident surface of the light guide and the second light-transmitting area, reducing or eliminating the appearance eccentricity, and improving the appearance of the electronic device while ensuring the amount of light entering the front camera module and the light guide. On the other hand, it can reduce the difficulty of assembling the electronic device, reduce the assembly time of the electronic device, improve the assembly efficiency, and reduce the assembly cost. On the other hand, due to the high position accuracy of the bracket structure, during the subsequent assembly of the front camera module, the front camera module can be prevented from colliding with the display screen, thereby preventing the display screen from being damaged by the collision, and improving the assembly yield of the electronic device.

[0021] In a possible implementation of the first aspect, it includes a middle plate, which is located on one side of the screen, and the middle plate includes a first identification straight edge; the first top plate is fixedly connected to the first side panel, and a first accommodating cavity is defined between the first top plate and the first side panel, and the first top plate includes a first outer surface and a first inner surface opposite to each other, and the first outer surface faces the screen; an identification groove is provided on the first side panel, and the identification groove is formed by a portion of the inner wall surface of the first side panel being recessed toward the outer wall surface of the first side panel; the identification groove includes: a first notch, a first groove bottom wall and a first groove side wall, the first groove bottom wall is opposite to the first notch, the first groove side wall is located between the first notch and the first groove bottom wall, the first groove side wall is parallel to the thickness direction of the first top plate, or in the direction from the first outer surface of the first top plate to the first inner surface of the first top plate, the first groove side wall extends toward the direction close to the first accommodating cavity; the reflectivity of the first groove bottom wall is different from the reflectivity of the first groove side wall.

[0022] In this way, the orthographic projection of the first groove sidewall on the first top panel can be formed into a second identification straight edge. By setting the reflectivity of the first groove bottom wall to be different from that of the first groove sidewall, the image recognition device can accurately and quickly identify the second identification straight edge, thereby improving assembly efficiency and the accuracy of the detection process. Furthermore, because the first groove sidewall is recessed outward relative to the other inner walls of the first side panel, the first groove bottom wall is prevented from being obscured by structures such as the first buffer, further improving the accuracy of the detection process.

[0023] In one possible implementation of the first aspect, the first groove sidewall is made of a different material than the first groove sidewall. This significantly increases the difference in reflectivity between the first groove bottom wall and the first groove sidewall, thereby increasing the color difference between the first groove bottom wall and the first groove sidewall in the fitted image, thereby enabling clear and accurate capture of the second identified straight edge.

[0024] In one possible implementation of the first aspect, the screen includes a stacked light-transmitting cover plate and a display screen, the display screen having a first light-transmitting aperture, and a light-entering surface opposing the first light-transmitting aperture. The front camera module includes a lens, a portion of which extends into the first light-transmitting aperture. This increases the focal length of the front camera module and improves the camera performance of the front camera module.

[0025] In one possible implementation of the first aspect, the non-display area includes a light-shielding area surrounding the periphery of the first light-transmitting area and the periphery of the second light-transmitting area. This prevents the structure on the display screen from being exposed, thereby improving the appearance of the electronic device.

[0026] In one possible implementation of the first aspect, the electronic device further includes a circuit board and a seal, the seal being sealed between the second bracket and the circuit board, and the optical sensor being located circumferentially inward of the seal and electrically connected to the circuit board. This improves the waterproof and dustproof properties of the optical sensor, preventing damage to the optical sensor from dust, moisture, liquids, and the like, thereby improving the reliability of the optical sensor.

[0027] In one possible implementation of the first aspect, the electronic device further includes a circuit board, the light sensor being electrically connected to the circuit board; the circuit board having a through hole formed therein, the first bracket being inserted through the through hole. This reduces the overlapped dimension of the bracket structure and the circuit board in the Z-axis direction, thereby reducing the thickness of the electronic device and facilitating a lightweight and thin design of the electronic device.

[0028] In a possible implementation of the first aspect, the light sensor includes at least one of an ambient light sensor, a color temperature sensor, and an anti-flicker sensor. In this way, the electronic device can automatically adjust the brightness of the screen or improve the shooting quality of the front camera module.

[0029] In the second aspect, the present application provides a bracket module, which includes a bracket structure and a light guide. The bracket structure includes a first bracket and a second bracket that are fixedly connected; the first bracket is used to fix the front setting head module; the light guide is fixedly connected to the second bracket.

[0030] In a possible implementation manner of the second aspect, the first bracket and the second bracket are an integral structural component.

[0031] Among them, the technical effects brought about by any implementation method in the second aspect can refer to the technical effects brought about by different implementation methods in the first aspect, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0056] In the description of the embodiments of this application, "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0057] In the embodiments of the present application, it should be understood that the directional terms mentioned, such as "top", "bottom", "inside", "outside", etc., are only references to the directions in the drawings.

[0060] To facilitate understanding, before introducing the electronic device in the embodiments of the present application in detail, the relevant terms involved in the embodiments of the present application are first explained.

[0061] Screen-to-body ratio: The ratio of the display area to the total screen area. The total screen area is the sum of the display area and the non-display area.

[0062] Axial direction: It can be understood as the direction in which the central axis of the described component is located, which can be equivalent to the extension direction of the described component.

[0063] Circumferential direction: It can be understood as the circumferential direction surrounding the axial direction.

[0065] Center: refers to the geometric center of the part being described. For example, if the part being described is a circle, the center of the part is the center of the circle.

[0066] Electronic devices are usually equipped with front camera modules, light sensors and other under-screen functional devices to realize functions such as front shooting of electronic devices and automatic adjustment of screen brightness. In order to enable the under-screen functional devices to realize their corresponding functions, the screen includes a non-display area, and the non-display area includes a light-transmitting area (such as the first light-transmitting area and the second light-transmitting area mentioned below). The light-transmitting area can provide an optical path for the under-screen functional devices, so that external light can pass through the screen to the under-screen functional devices. However, with the improvement of consumer demand, users have higher and higher requirements for the functions of electronic devices, and the number and types of under-screen functional devices are increasing, resulting in an increasing area of ​​the non-display area in the screen, affecting the screen-to-body ratio of electronic devices.

[0067] In the electronic device in the embodiment of the present application, the second bracket for fixing the light guide is fixedly connected to the first bracket for fixing the front camera module. During assembly, the first bracket and the second bracket can be assembled as a whole to the housing of the electronic device, which can avoid interference between the first bracket and the second bracket during the assembly process, and there is no need to reserve avoidance space between the first bracket and the second bracket. The distance between the light incident surface of the light guide and the light incident surface of the front camera module can be reduced, thereby reducing the distance between the first light-transmitting area and the second light-transmitting area, that is, the distance between the center of the first light-transmitting area and the center of the second light-transmitting area can be reduced, which is beneficial to reducing the area of ​​the non-display area in the screen, and further beneficial to improving the screen-to-body ratio of the electronic device.

[0068] Specifically, the electronic device 100 provided in the embodiment of the present application includes but is not limited to a mobile phone, a tablet computer, a personal computer, a laptop computer, a camera, a vehicle-mounted device, a wearable device (such as a watch or a bracelet), augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses or a VR helmet, etc.

[0069] Please refer to Figures 1 and 2. Figure 1 is a schematic diagram of the structure of an electronic device 100 provided in some embodiments of the present application, and Figure 2 is a cross-sectional view of the electronic device 100 shown in Figure 1 taken along line AA. In this embodiment, the electronic device 100 is described as a mobile phone. Specifically, the electronic device 100 may include a screen 10, a housing 20, a circuit board 30, a front camera module 40, a light sensor 60, a light guide 52, and the like.

[0070] It will be understood that FIG1 and FIG2 and the related figures below only schematically illustrate some components included in the electronic device 100, and the actual shape, actual size, actual position and actual structure of these components are not limited to FIG1 and FIG2 and the related figures below.

[0071] In the embodiment shown in FIG1 , the electronic device 100 is roughly in the shape of a rectangular flat plate. To facilitate the description of the various embodiments below, an XYZ coordinate system is established for the electronic device 100. Specifically, the width direction of the electronic device 100 is defined as the X-axis direction, the length direction of the electronic device 100 is defined as the Y-axis direction, and the thickness direction of the electronic device 100 is defined as the Z-axis direction. It is understood that the coordinate system setting of the electronic device 100 can be flexibly set according to actual needs and is not specifically limited here. In addition, in some other embodiments, the shape of the electronic device 100 can also be a square flat plate, a circular flat plate, an elliptical flat plate, etc.

[0072] Screen 10 is used to display images, videos, and the like. Referring to Figure 2 , screen 10 may include a translucent cover plate 11 and a display screen 12. Translucent cover plate 11 and display screen 12 are stacked and fixedly connected. Translucent cover plate 11 primarily protects display screen 12 and provides dust protection. Materials for translucent cover plate 11 include, but are not limited to, glass and plastic.

[0073] Continuing with Figure 2, the display screen 12 includes a display surface 121 and a non-display surface 122 that face each other. The display surface 121 faces the light-transmitting cover plate 11. That is, the light-transmitting cover plate 11 is disposed on the side of the display screen 12 that the display surface 121 faces. The display surface 121 has a display interface for displaying images and videos. When the electronic device 100 is in use, the display surface 121 of the display screen 12 can face the user to present images or videos to the user.

[0074] The display screen 12 may be a flexible display screen or a rigid display screen. For example, the display screen 12 may be an organic light-emitting diode (OLED) display screen, a quantum dot light-emitting diode (QLED) display screen, or the like.

[0075] In order to allow external ambient light to pass through the screen 10 and reach the front camera module 40, light sensor 60 and other under-screen functional components to ensure the amount of light entering the under-screen functional components, please refer to Figure 3, which is an enlarged view of the area C in the electronic device shown in Figure 1. The screen 10 includes a display area 101 and a non-display area 102. The display area 101 can be arranged around the non-display area 102. In this embodiment, the display area 101 is arranged around the non-display area 102. It will be understood that in other embodiments, the non-display area 102 can also be located outside the circumference of the display area 101.

[0076] In some embodiments, referring to FIG3 , the non-display area 102 includes a first light-transmitting area 102a, a second light-transmitting area 102b, and a light-shielding area 102c. The light-shielding area 102c can be connected between the first light-transmitting area 102a and the second light-transmitting area 102b and surround the outer periphery of the first light-transmitting area 102a and the outer periphery of the second light-transmitting area 102b. The outer contours of the first light-transmitting area 102a and the second light-transmitting area 102b can be circular, elliptical, square, rectangular, etc.

[0077] Please refer to Figure 4, which is a partial exploded view of the screen 10 in the electronic device 100 shown in Figure 1. A light-shielding layer 111 is provided on the surface of the transparent cover plate 11 facing the display screen 12. This light-shielding layer 111 may be a layer of ink, paint, or the like. The area corresponding to the light-shielding layer 111 may form a light-shielding area 102c.

[0078] To increase the light transmittance of the first light-transmitting area 102a and the second light-transmitting area 102b on the screen 10, as shown in FIG4 , a first light-transmitting hole 123 and a second light-transmitting hole 124 are provided on the display screen 12. Both the first light-transmitting hole 123 and the second light-transmitting hole 124 are through holes. That is, the first light-transmitting hole 123 and the second light-transmitting hole 124 both penetrate the display surface 121 and the non-display surface 122 of the display screen 12. The first light-transmitting hole 123 can be a circular hole, an elliptical hole, a square hole, a rectangular hole, etc. The shape of the first light-transmitting hole 123 can be the same as the outer contour of the first light-transmitting area 102a. Similarly, the shape of the second light-transmitting hole 124 can be the same as the outer contour of the second light-transmitting area 102b.

[0079] The orthographic projection of the first light-transmitting hole 123 on the first reference plane may coincide with the orthographic projection of the first light-transmitting region 102a on the first reference plane, or the orthographic projection of the first light-transmitting hole 123 on the first reference plane may be located within the orthographic projection of the first light-transmitting region 102a on the first reference plane. Similarly, the orthographic projection of the second light-transmitting hole 124 on the first reference plane may coincide with the orthographic projection of the second light-transmitting region 102b on the first reference plane, or the orthographic projection of the second light-transmitting hole 124 on the first reference plane may be located within the orthographic projection of the second light-transmitting region 102b on the first reference plane. The first reference plane is perpendicular to the Z-axis.

[0080] In some embodiments, referring to FIG3 , the non-display area 102 may be in the shape of an elongated strip. The outer contour of the non-display area 102 may be in the shape of a runway, a rectangle, an ellipse, or the like. The first light-transmitting area 102a and the second light-transmitting area 102b may be arranged at intervals in the longitudinal direction of the non-display area 102. The longitudinal direction of the non-display area 102 is perpendicular to the Z-axis direction. For example, in the embodiment shown in FIG3 , the longitudinal direction of the non-display area 102 is parallel to the X-axis direction, and the first light-transmitting area 102a and the second light-transmitting area 102b are spaced apart in the X-axis direction. The line connecting the center of the first light-transmitting area 102a and the center of the second light-transmitting area 102b is parallel to the first direction.

[0081] The housing 20 is used to protect the internal electronic components of the electronic device 100. Referring to Figure 2, the housing 20 includes a middle frame 21 and a back cover 22. The middle frame 21 includes a frame 211 and a middle plate 212. The frame 211 can be annular. For example, the frame 211 can be roughly rectangular. The transparent cover 11 and the back cover 22 are both fixedly connected to the frame 211, and the transparent cover 11, the back cover 22 and the frame 211 form an internal storage space of the electronic device 100, which can accommodate the display screen 12, the circuit board 30, the front camera module 40, etc.

[0082] The middle plate 212 is fixed around the inner surface of the frame 211 and is located between the screen 10 and the back cover 22. Specifically, the screen 10, the middle plate 212, and the back cover 22 can be stacked in the Z-axis direction. The middle plate 212 serves as the supporting frame of the electronic device 100, and the circuit board 30, the front camera module 40, etc. can be fixed to the middle plate 212.

[0083] The circuit board 30 is used to integrate electronic components. The circuit board 30 can be used to electrically connect the various electronic components within the electronic device 100 and can be used to perform operations such as signal control and data signal processing on the electronic components. The circuit board 30 includes, but is not limited to, a printed circuit board (PCB). The circuit board 30 can be a rigid circuit board, a flexible circuit board, or a rigid-flexible combination circuit board. The circuit board 30 can be secured to the midplane 212 by gluing, snapping, welding, screwing, or other methods.

[0084] The electronic components include but are not limited to processors. The processor can provide display data to the display screen 12 to drive the display screen 12 to display images. For example, the above-mentioned processor may include one or more processing units. For example, the processor may include an application processor (AP), a modem processor, a graphics processor (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU), etc. Among them, different processing units can be independent devices or integrated into one or more processors.

[0085] In addition, the electronic device 100 may also include an external memory interface electrically connected to the processor, an internal memory, a universal serial bus (USB) interface, a charging management module, a power management module, a battery, an antenna, a mobile communication module, a wireless communication module, an audio module, a speaker, a receiver, a microphone, a headphone interface, a sensor module, buttons, a rear camera module, etc.

[0086] The front camera module 40 is used for taking photos and videos. It is located within the internal storage space of the electronic device 100 and serves as an under-screen functional device. Referring to Figure 2 , the front camera module 40 has a light-entering surface 40a, which is opposite the first light-transmitting area 102a. This allows scene light to enter the light-entering surface 40a of the front camera module 40 through the first light-transmitting area 102a.

[0087] In some embodiments, the light incident surface 40a is exposed outside the first light transmission hole 123. That is, the orthographic projection of the light incident surface 40a on the first reference plane coincides with the orthographic projection of the first light transmission hole 123 on the first reference plane, or the orthographic projection of the light incident surface 40a on the first reference plane is located within the orthographic projection of the first light transmission hole 123 on the first reference plane. The first reference plane is perpendicular to the Z-axis. In this way, the light incident surface 40a of the front camera module 40 can be prevented from being blocked by the display screen 12, which can increase the amount of light entering the front camera module 40 and improve the shooting effect of the front camera module 40.

[0088] The front camera module 40 can be fixedly connected to the middle plate 212. In some embodiments, referring to FIG. 2 , the electronic device 100 includes a first bracket 511, and the front camera module 40 can be fixedly connected to the middle plate 212 with the aid of the first bracket 511. Specifically, during the assembly process, the first bracket 511 can be first fixedly connected to the middle plate 212, and then the front camera module 40 can be assembled to the first bracket 511. In this way, the assembly position of the front camera module 40 can be limited by the first bracket 511, which can prevent the front camera module 40 from colliding with the display screen 12 during the assembly process, thereby improving the assembly yield of the electronic device 100 and reducing the difficulty of assembling the front camera module 40.

[0089] Continuing with Figure 2, the electronic device 100 also includes a light sensor 60, which can be electrically connected to the circuit board 30. The light sensor 60 is a device that can sensitively sense light energy from ultraviolet to infrared light and convert it into an electrical signal. The light sensor 60 is a sensing device primarily composed of a photosensor. The light sensor 60 can be used to assist the front camera module 40 in capturing images, thereby improving the quality of the images captured by the front camera module 40. Furthermore, the light sensor 60 can also be used to implement the automatic adjustment function of the screen 10.

[0090] The light sensor 60 is a functional device under the screen. Referring to Figure 2, the light sensor 60 has a photosensitive surface 60a, and the orientation of the photosensitive surface 60a is the same as the orientation of the display surface 121 of the display screen 12. The light sensor 60 may include at least one of an ambient light sensor, a color temperature sensor, an anti-flicker light sensor, and an infrared light sensor (also referred to as a proximity light sensor). Among them, the color temperature sensor can detect the color temperature of the environment during shooting, so that the color of the captured picture is more accurate. At the same time, for different shooting scenes, it automatically recognizes the captured image through artificial intelligence and optimizes the captured image in a targeted manner, resulting in a better photo display effect. The anti-flicker light sensor can suppress the flicker generated when taking pictures. In indoor light, artificial light and other environments, it can accurately monitor the flicker frequency of the ambient light source, provide real-time exposure adjustment, and thus improve the shooting quality. The ambient light sensor can be used to detect the light intensity of the environment in which the electronic device 100 is located, so as to realize the function of automatically adjusting the brightness of the screen 10.

[0091] When the optical sensor 60 includes multiple sensors, the multiple sensors can be integrated into one, so as to reduce the volume of the optical sensor 60 and save the space occupied by the optical sensor 60.

[0092] The light guide 52 is used to guide ambient light to the photosensitive surface 60a of the light sensor 60. Referring to Figure 2 , the light guide 52 and the front camera module 40 are arranged in a first direction e1. The first direction e1 can be parallel to the length of the non-display area 102. In other words, the first direction e1 is perpendicular to the Z-axis.

[0093] Continuing with FIG2 , the light guide 52 includes a light inlet surface 52a and a first light outlet surface 52b. The light inlet surface 52a is opposite the second light-transmitting region 102b, and the light outlet surface faces the light sensor 60. Furthermore, the light outlet surface faces the light sensing surface 60a of the light sensor 60. That is, the light sensor 60 is located on the side of the light outlet surface of the light guide 52 that faces it. This allows ambient light to enter the light guide 52 through the light inlet surface 52a and, guided by the light guide 52, exit through the first light outlet surface 52b. The ambient light exiting the first light outlet surface 52b can then be directed toward the light sensing surface 60a and sensed by the light sensor 60. This directs more light to the light sensor 60, increasing the amount of light entering the light sensor 60 and improving the accuracy with which the light sensor 60 collects relevant parameters of ambient light (light intensity, light frequency, color temperature, etc.).

[0094] In some embodiments, the orthographic projection of the photosensitive surface 60a on the second reference plane overlaps with the orthographic projection of the first light-emitting surface 52b on the second reference plane. Furthermore, the orthographic projection of the photosensitive surface 60a on the second reference plane can be located within the orthographic projection of the first light-emitting surface 52b on the second reference plane, or the orthographic projection of the photosensitive surface 60a on the second reference plane can coincide with the orthographic projection of the first light-emitting surface 52b on the second reference plane. The second reference plane is perpendicular to the arrangement direction of the photosensitive surface 60a and the first light-emitting surface 52b. Exemplarily, the second reference plane is perpendicular to the Z-axis direction. In this way, the amount of light entering the light sensor 60 can be further increased, which is beneficial to improving the accuracy of the light sensor 60 in collecting relevant parameters of ambient light.

[0095] 2 , the light guide 52 can be fixedly connected to the middle plate 212. In some embodiments, the electronic device 100 further includes a second bracket 512, and the light guide 52 is fixedly connected to the second bracket 512. Thus, the light guide 52 can be assembled to the middle plate 212 with the help of the second bracket 512.

[0096] For example, during assembly, the light guide 52 can be first assembled to the second bracket 512, and then the second bracket 512 and the light guide 52 can be assembled integrally to the middle plate 212. Since the light guide 52 usually needs to be manually assembled to the electronic device 100, the provision of the second bracket 512 can reduce the difficulty of assembling the light guide 52, thereby preventing the light inlet surface 52a and the first light outlet surface 52b of the light guide 52 from being contaminated by dust, fingerprints, etc. during the assembly process, thereby improving the assembly yield of the electronic device 100.

[0097] In this embodiment, the second bracket 512 and the first bracket 511 need to be assembled to the middle plate 212 separately. In this case, in order to avoid interference between the second bracket 512 and the first bracket 511 during the assembly process, the second bracket 512 and the first bracket 511 need to be spaced apart to reserve a clearance between the second bracket 512 and the first bracket 511. This will increase the distance between the light-entering surface 52a of the light guide 52 and the light-entering surface 40a of the front camera module 40 in the first direction, thereby increasing the distance d between the first light-transmitting area 102a and the second light-transmitting area 102b. In other words, the distance between the center of the first light-transmitting area 102a and the center of the second light-transmitting area 102b will increase, thereby increasing the area of ​​the non-display area 102 in the screen 10, which is not conducive to improving the screen-to-body ratio of the screen 10.

[0098] It should be noted that the spacing between two components described in the embodiments of the present application refers to the minimum spacing between the two components. For example, the spacing between the light-entering surface 52a and the light-entering surface 40a in the first direction refers to the minimum spacing between the light-entering surface 52a and the light-entering surface 40a in the first direction. The spacing between the first light-transmitting area 102a and the second light-transmitting area 102b refers to the minimum spacing between the first light-transmitting area 102a and the second light-transmitting area 102b. For example, the spacing d shown in Figure 2.

[0099] In order to reduce the area of ​​the non-display region 102 in the screen 10 while ensuring the amount of light entering the functional components under the screen, please refer to Figures 5 and 6. Figure 5 is a partial stereoscopic view of an electronic device 100 provided in other embodiments of the present application, and Figure 6 is an exploded view of the electronic device 100 shown in Figure 5. The difference between the electronic device 100 in this embodiment and the electronic device 100 in the above embodiment is that, in addition to including the screen 10, the housing 20, the circuit board 30, the front camera module 40, the light guide 52, and the light sensor 60, the electronic device 100 in this embodiment also includes a bracket structure 51.

[0100] Specifically, please refer to Figures 7-8. Figure 7 is an assembly stereogram of the bracket structure 51, the light guide 52 and the front camera module 40 in the electronic device 100 shown in Figure 5, and Figure 8 is an exploded view of the assembly schematic diagram shown in Figure 7. The bracket structure 51 includes a first bracket 511 and a second bracket 512. The first bracket 511 and the second bracket 512 can be arranged in a first direction (that is, the length direction of the non-display area 102). The first bracket 511 is fixedly connected to the second bracket 512. The first bracket 511 is used to fix the front camera module 40, and the second bracket 512 is used to fix the light guide 52.

[0101] In this way, by fixing the first bracket 511 to the second bracket 512, the first bracket 511 and the second bracket 512 can be assembled as a whole to the shell 20 of the electronic device 100 during assembly. For example, at least one of the light guide 52 and the front camera module 40 can be assembled to the bracket structure 51 to form a bracket module, and then the bracket module can be assembled as a whole to the shell 20 of the electronic device 100. Alternatively, the bracket structure 51 can be assembled to the shell 20 of the electronic device 100 first, and then the front camera module 40 and the light guide 52 can be assembled to the shell 20 respectively. This can avoid interference between the first bracket 511 and the second bracket 512 during the assembly process, and there is no need to reserve avoidance space between the first bracket 511 and the second bracket 512.

[0102] Thus, on the one hand, the distance between the light-entering surface 52a of the light guide 52 and the light-entering surface 40a of the front camera module 40 can be reduced, thereby reducing the distance between the center of the first light-transmitting area 102a and the center of the second light-transmitting area 102b, which is beneficial to reducing the area of ​​the non-display area 102 in the screen 10, thereby facilitating an improvement in the screen-to-body ratio of the electronic device 100; on the other hand, the size of the support structure 51 in the first direction e1 can be reduced, which can reduce structural redundancy and the space occupied by the support structure 51, making the structure of the electronic device 100 more compact, optimizing the structural layout of the electronic device 100, and facilitating a miniaturized design of the electronic device 100. In addition, the electronic device 100 in this embodiment can achieve the appearance effect of a front dual camera even if only one front camera module 40 is provided.

[0103] In some embodiments, the first bracket 511 and the second bracket 512 are integrally formed. For example, the first bracket 511 and the second bracket 512 can be formed by injection molding (including primary injection molding, secondary injection molding, metal insert molding, etc.), metal powder injection molding (MIM), stamping, hot forging, or other processes.

[0104] In this way, on the one hand, the connection reliability between the first bracket 511 and the second bracket 512 can be improved, and the processing technology of the bracket structure 51 can be simplified, thereby reducing the cost of the bracket structure 51; on the other hand, the assembly error between the first bracket 511 and the second bracket 512 can be reduced, which is conducive to reducing the assembly deviation between the light guide 52 and the front camera module 40, and can improve the assembly accuracy of the light guide 52 and the front camera module 40, thereby improving the concentricity of the light incident surface 40a of the front camera module 40 and the first light-transmitting area 102a, as well as the concentricity of the light incident surface 52a of the light guide 52 and the second light-transmitting area 102b, reducing or eliminating the appearance eccentricity, and improving the appearance of the electronic device 100 while ensuring the amount of light entering the front camera module 40 and the light guide 52; on the other hand, the assembly steps of the electronic device 100 can be reduced, the assembly difficulty can be reduced, and the assembly working hours can be saved, the assembly efficiency can be improved, and the cost can be reduced.

[0105] It is understandable that, in other embodiments, the first bracket 511 and the second bracket 512 may also be fixedly connected by bonding, welding, clamping, screw connection, etc.

[0106] Please refer to Figures 8-9. Figure 9 is a three-dimensional view of the bracket structure 51 in the electronic device 100 shown in Figure 5. The first bracket 511 includes a first top plate 5111 and a first side panel 5112. The first top plate 5111 is plate-shaped. For example, the first top plate 5111 can be a polygon such as a rectangle or trapezoid, or it can be a circle, an ellipse, an irregular shape, etc. The first top plate 5111 is provided with a first through hole 5111c. Specifically, referring to Figure 8 and Figure 9, the first top plate 5111 includes a first outer surface 5111a and a first inner surface 5111b that are opposite to each other in its thickness direction (e.g., the Z-axis direction in Figure 8). The first outer surface 5111a can face the display screen 12. The first through hole 5111c extends through the first outer surface 5111a and the first inner surface 5111b. The first through hole 5111c can be formed as a circular hole, an elliptical hole, a square hole, etc.

[0107] In some embodiments, the first top plate 5111 can be made of metal. For example, the material of the first top plate 5111 can be stainless steel, aluminum alloy, magnesium alloy, titanium alloy, or the like. This allows the overall structural strength of the support structure 51 to be increased while reducing the thickness of the first top plate 5111, thereby reducing the space occupied. Furthermore, when the front camera module 40 is a telephoto or zoom camera module, reducing the thickness of the first top plate 5111 can also help increase the focal length and zoom range of the front camera module 40, thereby improving the performance of the front camera module 40.

[0108] Of course, the material of the first top plate 5111 is not limited thereto. For example, in other embodiments, the material of the first top plate 5111 may be plastic.

[0109] The first side panel 5112 is a frame structure. In some embodiments, as shown in FIG9 , the first side panel 5112 may be an annular frame structure. In this embodiment, the first side panel 5112 may be substantially a rectangular annular frame. It is understood that in other embodiments, the first side panel 5112 may also be substantially a circular annular frame, an elliptical annular frame, or the like.

[0110] The first side panel 5112 is fixedly connected to the first top panel 5111 and extends circumferentially of the first top panel 5111. A first accommodating cavity 5113 is defined between the first side panel 5112 and the first top panel 5111. The first through hole 5111c communicates with the first accommodating cavity 5113. The first accommodating cavity 5113 has a first opening 5113a, which is opposite to the first top panel 5111.

[0111] The material of the first side panel 5112 can be plastic, rubber, etc. In this way, the material cost of the support structure 51 can be reduced, the weight of the support structure 51 can be reduced, and the wear resistance of the support structure 51 can be improved.

[0112] In some embodiments, referring to FIG9 , the first side panel 5112 includes a first side panel 5112a, a second side panel 5112b, a third side panel 5112c, and a fourth side panel 5112d. The first side panel 5112a and the second side panel 5112b are disposed opposite each other and are fixedly connected to opposite sides of the first top panel 5111, respectively. For example, the first side panel 5112a and the second side panel 5112b can be disposed opposite each other in the first direction e1. The first side panel 5112a can be generally formed as a flat plate. The second side panel 5112b can be generally formed as a flat plate, a curved plate, or the like.

[0113] The third side panel 5112c and the fourth side panel 5112d are arranged opposite each other, and the third side panel 5112c and the fourth side panel 5112d are respectively fixedly connected to the two sides of the first top panel 5111. Exemplarily, the third side panel 5112c and the fourth side panel 5112d can be arranged opposite each other in the second direction e2. The second direction e2 is different from the first direction e1. Exemplarily, the first direction can be parallel to the X-axis direction, and the second direction can be parallel to the Y-axis direction. The first side panel 5112 can be formed by the first side panel 5112a, the third side panel 5112c, the second side panel 5112b, and the fourth side panel 5112d connected in sequence. The third side panel 5112c and the fourth side panel 5112d can be formed as flat plates, curved plates, etc.

[0114] It is understood that the first side panel 5112 can be a single integral structural member or can be assembled from multiple parts through bonding, snap-fitting, threaded connections, etc. Furthermore, in other embodiments, the first side panel 5112 can also be a non-annular frame. In this case, the first side panel 5112 may not include at least one of the third side panel 5112c and the fourth side panel 5112d.

[0115] In some embodiments, in order to facilitate the connection between the first top plate 5111 and the first side panel 5112, please refer to Figures 10a and 10b. Figure 10a is an exploded view of the bracket structure 51 shown in Figure 9, and Figure 10b is a cross-sectional view of the bracket structure 51 shown in Figure 9 at line BB. The first bracket 511 includes a metal part 5110. The metal part 5110 includes the above-mentioned first top plate 5111 and a flange portion 5114. The flange portion 5114 is connected to the edge of the first top plate 5111 and is folded in a direction away from the first outer surface 5111a. In some embodiments, the first top plate 5111 and the flange portion 5114 can be an integrated structure.

[0116] The flange portion 5114 is used to secure to the first side panel 5112. Specifically, as shown in Figure 10b, at least a portion of the flange portion 5114 can be embedded within the first side panel 5112. For example, the metal member 5110 and the first side panel 5112 can be integrally connected via a metal insert injection molding process. This simplifies the processing of the first top panel 5111 and the first side panel 5112 and improves the reliability of the connection between the first top panel 5111 and the first side panel 5112.

[0117] On this basis, to further enhance the connection reliability between the first top panel 5111 and the first side panel 5112, as shown in Figure 10a, a plurality of embedding grooves 5114a are formed on the end of the flange portion 5114 distal from the first top panel 5111. The embedding grooves 5114a can penetrate both opposing surfaces of the flange portion 5114 in its thickness direction, as well as the end surface of the flange portion 5114 distal from the first top panel 5111. This helps increase the connection area between the flange portion 5114 and the first side panel 5112, thereby enhancing the connection reliability between the first top panel 5111 and the first side panel 5112. Furthermore, the structure is simple and easy to manufacture.

[0118] Please refer to Figure 11, which is a cross-sectional view taken along line CC of the assembly perspective view shown in Figure 7. The front camera module 40 includes a housing 41, a lens 42, and other components. The lens 42 is disposed within the housing 41. The front camera module 40 can be connected to the first bracket 511 via the housing 41. For example, the housing 41 can be fixedly connected to the first side panel 5112 of the first bracket 511 by means of a snap-fit, adhesive, or other means.

[0119] The lens 42 has a light-entering surface 40a and a second light-emitting surface 40b. That is, the light-entering surface 40a of the front camera module 40 is formed on the lens 42. Scene light enters the lens 42 through the light-entering surface 40a and exits through the second light-emitting surface 40b. The lens 42 can be a telephoto lens, a zoom lens, a wide-angle lens, or the like. That is, the front camera module 40 can be a telephoto camera module, a zoom camera module, or a wide-angle camera module.

[0120] Referring to Figure 11 , the front camera module 40 is fixedly connected to the first bracket 511. The front camera module 40 is located circumferentially inward of the first side panel 5112. Specifically, a portion of the front camera module 40 is located within the first accommodating cavity 5113. The outer contour of the housing 41 can be adapted to the shape of the inner wall of the first accommodating cavity 5113. The lens 42 of the front camera module 40 can be inserted into the first through hole 5111c.

[0121] In some embodiments, referring to FIG. 11 , a first buffer member 54 is provided between the front camera module 40 and the first top plate 5111. The first buffer member 54 can be adhesively fixed to the first inner surface 5111b of the first top plate 5111. The first buffer member 54 is annular. The first buffer member 54 can be disposed around the periphery of the first through hole 5111c. The first buffer member 54 can provide a buffering and protective function, and can also provide a waterproof and dustproof function. For example, the first buffer member 54 can be foam.

[0122] 8 and 9 , the second bracket 512 includes a second top plate 5121, a second side panel 5122, and a light shielding tube 5123. The second top plate 5121 is generally plate-shaped. The thickness of the second top plate 5121 is parallel to that of the first top plate 5111. A second through hole 5121c is defined in the second top plate 5121.

[0123] Specifically, referring to FIG8 in conjunction with FIG9 , the second top plate 5121 includes a second outer surface 5121a and a second inner surface 5121b that face each other in the thickness direction (e.g., the Z-axis direction in FIG9 ). A second through hole 5121c extends through the second outer surface 5121a and the second inner surface 5121b. The second outer surface 5121a may face the display screen 12. The second through hole 5121c may be formed in a circular hole, an elliptical hole, a square hole, or the like.

[0124] Please continue to refer to Figure 8 and combine it with Figure 9. The light-shielding tube 5123 is fixedly connected to the second top plate 5121. The light-shielding tube 5123 is formed into a cylindrical structure with both ends open. The light-shielding tube 5123 is arranged around the second through hole 5121c and protrudes from the second outer surface 5121a of the second top plate 5121. The light-shielding tube 5123 can be coaxially arranged with the second through hole 5121c. That is, the central axis of the light-shielding tube 5123 and the central axis of the second through hole 5121c can roughly coincide. In some embodiments, the light-shielding tube 5123 and the second top plate 5121 are an integrated structure. Exemplarily, the light-shielding tube 5123 and the second top plate 5121 can be integrally injection molded, which is simple in process and easy to process.

[0125] In some embodiments, as shown in Figures 9 and 10a, the second side panel 5122 is an annular frame structure. The outer contour of the second side panel 5122 can be polygonal, circular, elliptical, or irregular. The second side panel 5122 is fixedly connected to the second top panel 5121 and extends along the circumference of the second top panel 5121. A second accommodating cavity 5124 can be defined between the second side panel 5122 and the second top panel 5121. For example, the second side panel 5122 can be disposed around the edge of the second top panel 5121.

[0126] Referring to Figures 9-10a, the second side panel 5122 includes a first extension section 5122a and a second extension section 5122b, which are arranged circumferentially around the second top panel 5121. The first extension section 5122a can extend in a straight line. The second extension section 5122b can include a plurality of first sub-panel sections, which are arranged circumferentially around the second top panel 5121, with adjacent first sub-panel sections connected. The second extension section 5122b can be connected to the first extension section 5122a at both ends of the circumferential direction of the second top panel 5121, respectively.

[0127] Referring to Figure 10b , the second side panel 5122 of the second bracket 512 can be fixedly connected to the first side panel 5112 of the first bracket 511. In some embodiments, the second side panel 5122 can be fixedly connected to the first side panel 5112a of the first side panel 5112 via a first extension 5122a. For example, the outer wall surface of the second side panel 5122 can be fixedly connected to the outer wall surface of the first side panel. This facilitates the fixed connection of the first bracket 511 and the second bracket 512 into a single unit, increases the connection area between the first bracket 511 and the second bracket 512, and improves the reliability of the connection between the first bracket 511 and the second bracket 512.

[0128] 10b , the outer wall of the first side panel 5112 refers to the wall of the first side panel 5112 away from the central axis O1 of the first through hole 5111c, and the outer wall of the second side panel 5122 refers to the wall of the second side panel 5122 away from the central axis O2 of the second through hole 5121c.

[0129] In some embodiments, a portion of the outer wall of the second side panel 5122 is aligned with a portion of the outer wall of the first side panel 5112. Specifically, referring to FIG10b , the outer wall of the first extension section 5122a can be aligned with the outer wall of the first side panel 5112a. This reduces structural redundancy in the support structure 51, making the support structure 51 more compact. Furthermore, the support structure 51 can be further reduced in size in the arrangement direction of the first and second support brackets 511 and 512, thereby further reducing the distance between the centers of the first and second light-transmitting areas 102a and 102b, reducing the area of ​​the non-display area 102 of the screen 10 and increasing the screen-to-body ratio of the screen 10. Furthermore, the support structure 51 can be further reduced in overall footprint, facilitating assembly of the support structure 51, the light guide 52, and the front camera module 40 within the limited space of the electronic device 100, thereby facilitating a miniaturized design of the electronic device 100.

[0130] For example, the first extension section 5122a and the first side panel 5112a can be integrally connected via injection molding. Specifically, the first bracket 511 and the second bracket 512 can be separately formed and then integrally connected via injection molding, so that the outer wall surface of the first extension section 5122a aligns with the outer wall surface of the first side panel 5112a. Alternatively, the first and second side panels 5112 and 5122 can be directly integrally molded via injection molding. In this way, the first extension section 5122a and the first side panel 5112a can be formed as a single integral component. That is, the first bracket 511 and the second bracket 512 can share the same wall panel. This not only reduces structural redundancy in the bracket structure 51 and the size of the bracket structure 51 in the arrangement direction of the first and second brackets 511 and 512, but also improves the connection reliability between the first and second side panels 5112 and 5122. Furthermore, it simplifies the manufacturing process of the bracket structure 51, omitting the assembly steps of the bracket structure 51 and improving the production efficiency of the bracket structure 51.

[0131] Please refer to Figures 12 and 13. Figure 12 is a three-dimensional view of the light guide 52 in the electronic device 100 shown in Figure 6, and Figure 13 is a cross-sectional view of the light guide 52 shown in Figure 12 at line DD. The light guide 52 includes a light guide column 521 and a fixing base 522. The light guide column 521 is fixedly connected to the fixing base 522. In some embodiments, the light input surface 52a can be formed on a side surface of the light guide column 521 facing away from the fixing base 522, and the first light output surface 52b can be formed on a side surface of the fixing base 522 facing away from the light guide column 521. It can be understood that in other embodiments, the light input surface 52a can also be formed on other surfaces of the light guide column 521. Similarly, the first light output surface 52b can be formed on other surfaces of the fixing base 522, or the first light output surface 52b can also be formed on the light guide column 521.

[0132] In some embodiments, the area of ​​the first light-emitting surface 52b is larger than the area of ​​the light-incoming surface 52a. This helps increase the overlapping area of ​​the first light-emitting surface 52b and the light-sensitive surface 60a of the light sensor 60 on the second reference plane, thereby increasing the amount of light entering the light sensor 60. At the same time, it helps reduce the area of ​​the second light-transmitting region 102b corresponding to the light-incoming surface 52a, thereby reducing the area of ​​the non-display area 102 of the screen 10 and increasing the screen-to-body ratio of the screen 10. Thus, both the amount of light entering the light sensor 60 and the area of ​​the non-display area 102 can be considered.

[0133] Specifically, referring to Figures 12-13, the light guide column 521 is in the shape of an elongated strip. The light guide column 521 includes a first light guide segment 5211 and a second light guide segment 5212. The first light guide segment 5211 and the second light guide segment 5212 are arranged in the axial direction of the light guide column 521. The light inlet surface 52a is formed on the first light guide segment 5211, and the second light guide segment 5212 is fixedly connected to the surface of the first light guide segment 5211 on the side facing away from the light inlet surface 52a. The light guide column 521 can be fixedly connected to the fixing base 522 via the second light guide segment 5212.

[0134] Referring to Figures 12-13 , the cross-sectional area of ​​the second light guide segment 5212 gradually increases in the direction from the first light guide segment 5211 to the second light guide segment 5212. For example, the second light guide portion can be roughly truncated cone, prism, or the like. In this case, the cross-sectional area of ​​the first light guide segment 5211 can remain constant in the direction from the first light guide segment 5211 to the second light guide segment 5212. For example, the first light guide segment 5211 can be cylindrical, prismatic, or the like.

[0135] In this way, ambient light from the outside world enters the first light guide segment 5211 from the light entrance surface 52a, and after being transmitted from the first light guide segment 5211 to the second light guide segment 5212, it can be diverged in the second light guide segment 5212, which helps to increase the area of ​​the first light exit surface 52b, thereby increasing the amount of light entering the light sensor 60 and improving the detection accuracy of the light sensor 60. At the same time, the area of ​​the light entrance surface 52a can be reduced, thereby reducing the area of ​​the second light-transmitting area 102b corresponding to the light entrance surface 52a, thereby helping to reduce the area of ​​the non-display area 102 of the screen 10 and improving the screen-to-body ratio of the screen 10.

[0136] It is understood that in other embodiments, the cross-sectional area of ​​the first light guiding segment 5211 may also gradually increase in the direction from the first light guiding segment 5211 to the second light guiding segment 5212. In this way, the area of ​​the second light emitting surface 40b can be increased while the area of ​​the light incident surface 52a can be reduced.

[0137] The fixing base 522 can be generally flat. In some embodiments, referring to FIG. 13 , the fixing base 522 includes a connecting portion 5221 and a skirt portion 5222 , wherein the skirt portion 5222 is fixedly connected to the circumferential outer side of the connecting portion 5221 . The connecting portion 5221 is configured to be fixedly connected to the light guide column 521 , and the skirt portion 5222 is configured to be fixedly connected to the second bracket 512 .

[0138] The orthographic projection of the skirt portion 5222 on the third reference plane does not overlap with the orthographic projection of the light guide column 521 on the third reference plane. The third reference plane is perpendicular to the arrangement direction of the light guide column 521 and the fixing seat 522 (e.g., the Z-axis direction in FIG. 13 ). This allows the skirt portion 5222 to be located circumferentially outside the light guide column 521, forming a stepped surface between the light guide column 521 and the fixing seat 522, thereby facilitating the fixing of the light guide member 52 to the second bracket 512.

[0139] The light guide 52 can be made of a light-transmitting material such as glass or plastic. In this way, the light transmittance of the light guide 52 can be guaranteed, thereby ensuring the amount of light entering the light sensor 60 and improving the detection accuracy of the light sensor 60.

[0140] On this basis, to further improve the light transmittance of the light guide 52, as shown in Figures 12-13, a light-homogenizing film 523 is provided on the first light-emitting surface 52b of the light guide 52. The light-homogenizing film 523 is used to improve the uniformity, softness, and fullness of the light emitted from the first light-emitting surface 52b. The light-homogenizing film 523 can be bonded to the first light-emitting surface 52b. The material of the light-homogenizing film 523 includes, but is not limited to, polyethylene terephthalate (PET).

[0141] In some embodiments, the light guide 521 and the fixing base 522 can be an integral structural component. For example, the light guide 52 can be formed into an integral component using an injection molding process. This helps to improve the connection strength between the light guide 521 and the fixing base 522, and can also simplify the processing of the light guide 52, thereby reducing the processing cost of the light guide 52.

[0142] In some embodiments, please refer to Figure 11, the light guide 52 can be located on the circumferential inner side of the second side panel 5122. The light guide column 521 of the light guide 52 can be arranged in the light-shielding tube 5123. The light-shielding tube 5123 can play a light-shielding role to prevent light from leaking sideways in the circumferential direction of the light guide column 521. The light-shielding tube 5123 has a first tube opening 5123a at one end away from the second top plate 5121, and the light-inlet surface 52a of the light guide 52 is exposed at the first tube opening 5123a. In this way, when looking from the light-shielding tube 5123 to the first top plate 5111, the light-inlet surface 52a of the light guide 52 can be seen from the first tube opening 5123a.

[0143] Specifically, the light guide column 521 can be entirely located within the light-shielding tube 5123. Alternatively, a portion of the light guide member 52 can be disposed within the light-shielding tube 5123. In this case, a portion of the light guide column 521 can pass through the first tube opening 5123a and out of the light-shielding tube 5123. In other words, a portion of the light guide column 521 is located on the side of the light-shielding tube 5123 facing away from the first top plate 5111. This is sufficient as long as the light-incoming surface 52a can be visible from the first tube opening 5123a of the light-shielding tube 5123.

[0144] Continuing with FIG11 , the light guide 52 can be fixed to the second top plate 5121 via the skirt portion 5222 of the fixing base 522. Specifically, the surface of the skirt portion 5222 facing the light guide column 521 can be fixedly connected to the second inner surface 5121b of the second top plate 5121. For example, the skirt portion 5222 can be connected to the second inner surface 5121b of the second top plate 5121 by bonding, welding, clamping, screwing, riveting, or the like.

[0145] It is understandable that in other embodiments, the fixing seat 522 may also be fixedly connected to the second side panel 5122 .

[0146] In some embodiments, to further reduce the distance between the light-entering surface 52a of the light guide 52 and the light-entering surface 40a of the front camera module 40, refer to FIG11 and FIG13 . In a first direction e1, the maximum dimension of the fixing base 522 protruding from the light guide column 521 in a direction away from the first bracket 511 is a first dimension d1, and the maximum dimension of the fixing base 522 protruding from the light guide column 521 in a direction toward the first bracket 511 is a second dimension d2, where the first dimension d1 is greater than the second dimension d2. In this way, the distance between the light guide column 521 and the first bracket 511 can be reduced, thereby reducing the distance between the light-entering surface 52a of the light guide 52 and the light-entering surface 40a of the front camera module 40. As a result, the distance between the center of the first light-transmitting area 102a and the center of the second light-transmitting area 102b can be further reduced, thereby reducing the area of ​​the non-display area 102 and increasing the screen-to-body ratio of the screen 10. In addition, when the first bracket 511 includes the metal member 5110 , setting the first dimension d1 to be larger than the second dimension d2 can also prevent the fixing seat 522 from interfering with the flange portion 5114 of the metal member 5110 .

[0147] Specifically, in some embodiments, as shown in FIG12 , the skirt portion 5222 is an open ring. In the first direction e1, the skirt portion 5222 is located on the side of the light guide 521 facing away from the first bracket 511. In other words, the skirt portion 5222 is not provided on the side of the light guide 521 closer to the first bracket 511. The skirt portion 5222 is generally C-shaped. This ensures that the first dimension d1 is greater than the second dimension d2, and provides a simple structure and ease of fabrication.

[0148] It can be understood that in other embodiments, in the first direction e1, a skirt portion 5222 can be provided on both the side of the light guide column 521 facing away from the first bracket 511 and the side of the light guide column 521 close to the first bracket 511, as long as it is ensured that in the first direction e1, the size of the skirt portion 5222 located on the side of the light guide column 521 facing away from the first bracket 511 is larger than the size of the skirt portion 5222 located on the side of the light guide column 521 close to the first bracket 511.

[0149] Based on any of the above embodiments, referring to FIG. 10b and in conjunction with FIG. 11 , a portion of the second inner surface 5121b of the second top plate 5121 is recessed toward the second outer surface 5121a to form a recessed groove 5121d, which extends through the wall of the second through hole 5121c. The skirt portion 5222 is accommodated and fixed within the recessed groove 5121d. This reduces the overlapped dimension of the second top plate 5121 and the fixing seat 522 in the Z-axis direction, thereby reducing the space occupied by the second bracket 512 and the light guide 52 in the Z-axis direction, which is beneficial for reducing the thickness of the electronic device 100 and achieving a lightweight and thin design for the electronic device 100.

[0150] Referring to Figure 14 and Figure 15 , Figure 14 is a schematic diagram of the partial assembly of the middle frame 21 and screen 10 in the electronic device 100 shown in Figure 5 , and Figure 15 is a cross-sectional view of the electronic device 100 shown in Figure 5 taken along line EE. The middle plate 212 includes a first surface 212a and a second surface 212b that face each other. The first surface 212a faces the back cover 22, and the second surface 212b faces the screen 10. The bracket structure 51 can be fixedly connected to the middle plate 212.

[0151] The middle plate 212 is provided with a first avoidance hole 2121 and a second avoidance hole 2122. Specifically, the first avoidance hole 2121 and the second avoidance hole 2122 are through holes. That is, the first avoidance hole 2121 and the second avoidance hole 2122 both extend through the first surface 212a and the second surface 212b. The first avoidance hole 2121 and the second avoidance hole 2122 can be formed in a circular, elliptical, or square shape, etc. The shape of the first avoidance hole 2121 and the second avoidance hole 2122 can be the same or different.

[0152] Referring to Figure 15 , the first avoidance hole 2121 can be opposite the first light-transmitting area 102a, and the second avoidance hole 2122 can be opposite the second light-transmitting area 102b. The center of the first avoidance hole 2121 can coincide with the center of the first light-transmitting area 102a, and the center of the second avoidance hole 2122 can coincide with the center of the second light-transmitting area 102b. The light incident surface 40a of the front camera module 40 can be exposed through the first avoidance hole 2121, and the light incident surface 52a of the light guide 52 can be exposed through the second avoidance hole 2122.

[0153] Specifically, in some embodiments, the orthographic projection of the light incident surface 40a on the first reference plane is located within the orthographic projection of the first avoidance hole 2121 on the first reference plane, or the orthographic projection of the light incident surface 40a on the first reference plane coincides with the orthographic projection of the first avoidance hole 2121 on the first reference plane. In this way, the entire light incident surface 40a can be exposed outside the first avoidance hole 2121.

[0154] Similarly, the orthographic projection of the light-inlet surface 52a on the first reference plane is located within the orthographic projection of the second avoidance hole 2122 on the first reference plane, or the orthographic projection of the light-inlet surface 52a on the first reference plane coincides with the orthographic projection of the second avoidance hole 2122 on the first reference plane. In this way, the entire light-inlet surface 52a can be exposed to the second avoidance hole 2122.

[0155] In this way, the light incident surface 40a of the front camera module 40 and the light incident surface 52a of the light guide 52 can be prevented from being blocked by the middle plate 212, so that external ambient light can enter the front camera module 40 through the first light-transmitting area 102a and enter the light guide 52 through the second light-transmitting area 102b.

[0156] In some embodiments, as shown in Figures 14 and 15 , a portion of the first surface 212a of the middle plate 212 is recessed toward the second surface 212b to form a recessed groove 2123. Specifically, a portion of the support structure 51 can be accommodated and secured within the recessed groove 2123, while another portion is located outside the recessed groove 2123. Alternatively, the entire support structure 51 can be accommodated and secured within the recessed groove 2123. This reduces the overlap between the support structure 51 and the middle plate 212 in the Z-axis direction, thereby reducing the thickness of the electronic device 100 and achieving a lightweight and thin design for the electronic device 100.

[0157] In some embodiments, referring to Figures 14 and 15, the support structure 51 can be fixed to the sink 2123 by a first adhesive member 53. The first adhesive member 53 can be a double-sided adhesive, hot melt adhesive, etc. The structure is simple and easy to assemble.

[0158] For example, referring to FIG14 , the first adhesive member 53 is disposed around the first avoidance hole 2121 and the second avoidance hole 2122. Thus, the first adhesive member 53 provides a sealed connection between the support structure 51 and the middle plate 212, preventing dust, liquid, etc. from entering the interior of the electronic device 100 through the first avoidance hole 2121 and the second avoidance hole 2122, thereby improving the waterproof and dustproof performance of the electronic device 100.

[0159] It is understandable that in other embodiments, the middle plate 212 may not be provided with the above-mentioned sinking groove 2123 .

[0160] To further reduce the thickness of electronic device 100, as shown in FIG15 , a through hole 31 is defined in circuit board 30, and first bracket 511 is disposed through through hole 31. This reduces the overlap between bracket structure 51 and circuit board 30 in the Z-axis direction, thereby reducing the thickness of electronic device 100 and facilitating a thinner and lighter design for electronic device 100.

[0161] In some embodiments, referring to FIG. 15 , a seal 55 is provided between the second bracket 512 and the circuit board 30. The second bracket 512 is sealed to the circuit board 30 via the seal 55. The seal 55 can be fixedly attached to the end surface of the second side panel 5122 facing away from the light shielding tube 5123. The seal 55 can be secured to the second side panel 5122 by bonding, snapping, or other methods.

[0162] Please refer to Figure 15 in conjunction with Figure 16 , which illustrates the assembly of the support structure 51 shown in Figure 7 with the light guide 52, first buffer 54, and seal 55. Seal 55 can be annular. Optical sensor 60 can be positioned circumferentially inward of seal 55. This improves the waterproof and dustproof properties of optical sensor 60, preventing damage from dust, moisture, liquids, and the like, and enhancing its reliability.

[0163] In some embodiments, the sealing member 55 may be foam. In this way, the sealing member 55 not only seals but also provides a buffering and protective function, thereby reducing the stress between the second bracket 512 and the circuit board 30 and improving the reliability of the circuit board 30.

[0164] In order to improve the assembly accuracy of the support structure 51 and the middle frame 21, to further improve the concentricity between the light incident surface 40a of the front camera module 40 and the first light-transmitting area 102a, and the concentricity between the light incident surface 52a of the light guide 52 and the second light-transmitting area 102b, and to reduce or eliminate the appearance of eccentricity, the support structure 51 and the middle frame 21 are assembled using automated equipment (not shown). The automated equipment may include an image capture device. The image capture device may be a CCD camera (charge couple device). In this case, the automated equipment may also be referred to as a CCD device.

[0165] During assembly, the image capture device can be used to identify the positioning features on the middle frame 21 and the positioning features on the support structure 51, so that the support structure 51 can be assembled to the corresponding position on the middle frame 21. The principle of the image capture device identifying the positioning features on the middle frame 21 is that the positioning features of the structural components (such as the middle frame 21, support structure 51, etc.) have different reflectivity to light than other structures of the structural components, thereby enabling the recognition of the positioning features. In other words, the degree of reflectivity of the positioning features of the structural components is different from that of other structures of the structural components. Reflectivity refers to the ability of an object to reflect light.

[0166] In some embodiments, in order to reduce the difficulty of assembling the electronic device 100 , the light guide 52 can be assembled to the bracket structure 51 to form a bracket module, and then the bracket module can be assembled to the middle frame 21 through automated equipment.

[0167] After the light guide 52 is assembled to the bracket structure 51, the second through hole 5121c on the bracket structure 51 is blocked by the light guide 52 and cannot be recognized by the image capture device. In this case, in order to realize the automated assembly of the bracket structure 51 and the middle frame 21, please refer to Figure 16. An identification hole 5121e is provided on the second bracket 512, and the identification hole 5121e passes through the second top plate 5121 of the second bracket 512. The shape of the identification hole 5121e can be circular, elliptical, polygonal, etc. In this way, during assembly, the center a of the first through hole 5111c and the center b of the identification hole 5121e can be identified (also called grasped), and the line segment L1 connecting the center a of the first through hole 5111c and the center b of the identification hole 5121e can be fitted, and the line segment L1 is used as a positioning feature on the bracket module to realize the overall automated assembly of the bracket structure 51 and the light guide 52.

[0168] Specifically, please refer to FIG17, which is a flowchart of the assembly of the support structure 51, the light guide 52 and the middle frame 21 of the electronic device 100 shown in FIG5. The assembly method of the electronic device 100 includes:

[0169] Step S100: Providing a middle frame 21, capturing the center c of the first avoidance hole 2121 and the center d of the second avoidance hole 2122 on the middle frame 21 using an image capture device, and fitting a line segment L2 connecting the center c of the first avoidance hole 2121 and the center d of the second avoidance hole 2122; wherein, the angle between the line segment L3 connecting the center a of the first through hole 5111c and the center e of the second through hole 5121c and the line segment L1 is a first angle; illustratively, the first angle can be 90 degrees, 75 degrees, 60 degrees, 45 degrees, 30 degrees, 15 degrees, 0 degrees, etc.;

[0170] Specifically, the automated equipment also includes an assembly fixture. During assembly, the middle frame 21 can be fixed in the assembly fixture to facilitate the image recognition device to capture the positioning features on the middle frame 21 (such as the center c of the first avoidance hole 2121 and the center d of the second avoidance hole 2122, etc.).

[0171] It should be noted that the "included angle" described in the embodiments of this application refers to the minimum angle between two straight lines or two line segments. Furthermore, in some embodiments, the assembly method of the electronic device 100 may further include, before step S100, step S000: assembling the screen 10 to the middle frame 21. In this case, in step S100, the middle frame 21 and the screen 10 are secured together to an assembly fixture.

[0172] Step S200: Providing a support module 50, the support module 50 including a support structure 51 and a light guide 52 fixedly connected to the support structure 51, capturing the center a of the first through hole 5111c and the center b of the marking hole using an image capture device, and fitting a line segment L1 connecting the center a of the first through hole 5111c and the center b of the marking hole;

[0173] In some embodiments, in order to further improve assembly efficiency and reduce assembly processes and assembly man-hours, the bracket module 50 further includes a first buffer member 54 and a sealing member 55 .

[0174] Step S300: Align the center a of the first through hole 5111c with the center c of the first avoidance hole 2121 so that the center a of the first through hole 5111c coincides with the center c of the first avoidance hole 2121, and then rotate the bracket module 50 so that the angle between the line segment L2 and the line segment L1 is the first angle.

[0175] In this way, the bracket module 50 and the middle frame 21 can be automatically assembled. On the one hand, the assembly accuracy of the bracket module 50 and the middle frame 21 can be improved, thereby improving the concentricity of the light incident surface 40a of the front camera module 40 and the first light-transmitting area 102a, as well as the concentricity of the light incident surface 52a of the light guide 52 and the second light-transmitting area 102b, reducing or eliminating the appearance eccentricity, and improving the appearance of the electronic device 100 while ensuring the amount of light entering the front camera module 40 and the light guide 52; on the other hand, it can reduce the assembly difficulty of the electronic device 100, reduce the assembly working hours of the electronic device 100, improve the assembly efficiency, and reduce the assembly cost; on the other hand, due to the high position accuracy of the bracket structure 51, in the subsequent assembly process of the front camera module 40, it can also prevent the front camera module 40 from colliding with the display screen 12, thereby preventing the display screen 12 from being damaged due to the collision, and improving the assembly yield of the electronic device 100.

[0176] Specifically, the automated equipment also includes a manipulator. During assembly, the manipulator can grab the bracket module 50 and assemble the bracket module 50 to the assembly position on the middle frame 21. Exemplarily, the manipulator can include a suction head, please refer to steps S200 and S300 in Figure 17. The bracket module 50 includes an adsorption film 56, which is fixedly connected to the first side panel 5112, and the adsorption film 56 is arranged opposite to the first top plate 5111. The manipulator can grasp the bracket module 50 by adsorption cooperation with the adsorption film 56 through the suction head. The adsorption film 56 can be assembled to the middle frame 21 together with the bracket module 50, and when assembling the front camera module 40, the adsorption film 56 can be torn off.

[0177] To prevent the adsorption film 56 from interfering with the image recognition device's recognition of positioning features such as the center a of the first through hole 5111c and the center c of the first avoidance hole 2121, the adsorption film 56 is transparent. To facilitate identification, the adsorption film 56 is shown in dotted lines in FIG17 .

[0178] In some embodiments, the adsorption film 56 is a hard film to facilitate the adsorption and cooperation between the suction head and the adsorption film 56. For example, the adsorption film 56 can be made of hard plastic.

[0179] In some embodiments, the orthographic projection of the first accommodating cavity 5113 on the first reference plane is located within the orthographic projection of the adsorption film 56 on the first reference plane. Thus, the adsorption film 56 can block the opening of the first accommodating cavity 5113, preventing dust, liquid, etc. from entering the first cavity, thereby providing dustproof and waterproof effects.

[0180] To facilitate the removal of the adsorption film 56 from the bracket module 50 in subsequent steps, as shown in step S200 of FIG. 17 , the adsorption film 56 includes an adsorption portion 561 and a first tear-off portion 562. The adsorption portion 561 is fixedly connected to the first side panel 5112, and the first tear-off portion 562 is fixedly connected to the adsorption portion 561 and located circumferentially outside the first side panel 5112. This allows the first tear-off portion 562 to protrude from the outer wall of the first side panel 5112, making it easier to remove the adsorption film 56.

[0181] In some embodiments, in order to further ensure the assembly yield of the electronic device 100, the assembly method of the electronic device 100 also includes an inspection step (also called a re-judgment step), through which it can be determined whether the bracket module 50 is assembled in place.

[0182] Specifically, referring to step S300 in FIG. 17 , the middle frame 21 has a first identification straight edge L4, and the bracket module 50 has a second identification straight edge L5. When the center a of the first through hole 5111c coincides with the center c of the first avoidance hole 2121, and the center e of the second through hole 5121c coincides with the center d of the second avoidance hole 2122, the angle between the first identification straight edge L4 and the second identification straight edge L5 is a second angle. Exemplarily, the second angle can be 90 degrees, 75 degrees, 60 degrees, 45 degrees, 30 degrees, 15 degrees, 0 degrees, etc.

[0183] After the bracket module 50 is assembled to the middle frame 21, the assembly method of the electronic device 100 further includes:

[0184] Step S400: Grasp the center a of the first through hole 5111c and the center c of the first avoidance hole 2121, and determine whether the center a of the first through hole 5111c and the center c of the first avoidance hole 2121 coincide with each other;

[0185] Step S500: grab the first identified straight edge L4, grab the second identified straight edge L5, and determine whether the angle between the first identified straight edge L4 and the second identified straight edge L5 is a second angle.

[0186] When the center a of the first through hole 5111c coincides with the center c of the first avoidance hole 2121, and the angle between the first identification straight edge L4 and the second identification straight edge L5 is the second angle, the bracket module 50 is confirmed to be properly assembled. If the center a of the first through hole 5111c does not coincide with the center c of the first avoidance hole 2121, or the angle between the first identification straight edge L4 and the second identification straight edge L5 is not the second angle, the bracket module 50 is confirmed to be not properly assembled.

[0187] The order of step S400 and step S500 is irrelevant. Specifically, during the inspection process, step S400 may be performed first, and then step S500. Alternatively, step S500 may be performed first, and then step S400.

[0188] In some embodiments, to improve the recognition accuracy of the second straight edge L5 by the image recognition device, as shown in FIG16 , an identification slot K is provided on the first side panel 5112. The identification slot K is formed by recessing a portion of the inner wall of the first side panel 5112 toward the outer wall of the first side panel 5112. For example, the identification slot K can be formed on the second side panel 5112b. The identification slot K includes a first slot opening K1, a first slot bottom wall K2, and first slot side walls K3. The first slot bottom wall K2 opposes the first slot opening K1, and the first slot side walls K3 are located between the first slot opening K1 and the first slot bottom wall K2. The first slot side walls K3 are parallel to the central axis of the first through hole 5111c (i.e., along the thickness of the first top plate 5111), or extend from the first outer surface 5111a of the first top plate 5111 to the first inner surface 5111b of the first top plate 5111, toward the central axis of the first through hole 5111c. That is, in the direction from the first outer surface 5111a of the first top plate 5111 to the first inner surface 5111b of the first top plate 5111, the first groove side wall K3 extends toward the direction close to the first accommodating cavity 5113, and the reflectivity of the first groove bottom wall K2 is different from the reflectivity of the first groove side wall K3.

[0189] In this way, the orthographic projection of the first groove sidewall K3 on the first top plate 5111 forms the second identification straight edge L5. Furthermore, by setting the reflectivity of the first groove bottom wall K2 to be different from that of the first groove sidewall K3, the image recognition device can accurately and quickly identify the second identification straight edge L5, thereby improving assembly efficiency and the accuracy of the inspection process. Furthermore, because the first groove sidewall K3 is recessed outward relative to the other inner walls of the first side panel 5112, the first groove bottom wall K2 is prevented from being obscured by structures such as the first buffer member 54, further improving the accuracy of the inspection process.

[0190] In some embodiments, a portion of the first inner surface 5111b of the first top plate 5111 forms the first groove bottom wall K2, and a portion of the inner wall surface of the first side panel 5112 forms the first groove side wall K3. The first groove bottom wall K2 and the first groove side wall K3 are made of different materials. For example, the first groove bottom wall K2 is made of metal, while the first groove side wall K3 is made of plastic. This significantly increases the color difference between the first groove bottom wall K2 and the first groove side wall K3 in the fitted image, thereby enabling clear and accurate capture of the second identification straight edge L5.

[0191] Before assembling the support structure 51 to the electronic device 100, to improve the dustproof and waterproof performance of the support module 50, please refer to Figures 18 and 19. Figure 18 is a schematic structural diagram of the support module 50 provided in other embodiments of the present application, and Figure 19 is an exploded view of the support module 50 shown in Figure 18. In addition to the support structure 51, the light guide 52, and the adsorption film 56, the support module 50 also includes a dustproof component 57.

[0192] Specifically, the dustproof assembly 57 includes a first dustproof layer 571, a second dustproof layer 572, and a buffer layer 573. The first dustproof layer 571 is disposed on the first outer surface 5111a of the first top plate 5111 and the second outer surface 5121a of the second top plate 5121. The first dustproof layer 571 covers the first through hole 5111c and surrounds the outer circumference of the light-shielding tube 5123.

[0193] The buffer layer 573 is annular and is fixedly connected to the side surface of the first dustproof layer 571 facing away from the second top plate 5121. Exemplarily, the buffer layer 573 can be fixedly connected to the first dustproof layer 571 via a second adhesive 574. The buffer layer 573 can be made of foam, rubber, silicone, etc. The second dustproof layer 572 is fixedly connected to the end surface of the buffer layer 573 facing away from the first dustproof layer 571. A dustproof cavity is defined between the second dustproof layer 572, the buffer layer 573 and the first top plate 5111. The light-shielding tube 5123 is located in the dustproof cavity.

[0194] This prevents dust from contaminating the light guide 52 and prevents dust, liquid, etc. from entering the first accommodating cavity 5113 of the first bracket 511, thereby improving the dust and water resistance of the bracket module 50. Furthermore, before assembling the bracket module 50 to the middle frame 21, the dustproof assembly 57 can be completely removed by removing the first dustproof layer 571, which improves the removal efficiency of the dustproof assembly 57 and saves assembly time. Specifically, the first dustproof layer 571 can be removed by a robot.

[0195] Both the first dustproof layer 571 and the second dustproof layer 572 can be release film layers.

[0196] In some embodiments, in order to facilitate the overall removal of the dustproof component 57 from the bracket module 50 , please refer to Figures 18-19 , a second tear-off portion 575 is provided on the first dustproof layer 571 , and the second tear-off portion 575 is located on the circumferential outer side of the first dustproof layer 571 .

[0197] According to the description of the above embodiments, the electronic device 100 in this embodiment can ensure the assembly consistency of the first bracket 511 and the second bracket 512, and can improve the assembly accuracy through assembly with automated equipment, which can effectively reduce the appearance of the forward camera eccentricity and improve the assembly yield of the electronic device 100.

[0198] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0199] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
