In this way, the distance between the light guide and the first bracket can be reduced, and then the distance between the light entrance surface of the light guide and the light entrance surface of the front camera module can be reduced. Thus, 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.

On the other hand, it can reduce the difficulty of assembling the electronic device, reduce the assembly hours 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, in 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 due to collision, and improving the assembly yield of the electronic device.

[0021] In this way, the orthographic projection of the first groove side wall on the first top plate can be formed as the second identification straight edge, and by setting the reflectivity of the first groove bottom wall to be different from the reflectivity of the first groove side wall, the image recognition device can accurately and quickly identify the second identification straight edge, which can improve the assembly efficiency and the accuracy of the detection process. In addition, since the first groove side wall is recessed outward relative to the other inner wall surfaces of the first side panel, the first groove bottom wall can be prevented from being blocked by structures such as the first buffer, thereby further improving the accuracy of the detection process.

[0022] In a possible implementation of the first aspect, the material of the first groove sidewall is different from the material of the first groove sidewall. In this way, the difference in reflectivity between the first groove bottom wall and the first groove sidewall is large, which can increase the color difference between the first groove bottom wall and the first groove sidewall in the fitting image, so that the second identification straight edge can be clearly and accurately captured.

[0026] In a possible implementation of the first aspect, the electronic device further includes: a circuit board, and the light sensor is electrically connected to the circuit board; the circuit board is provided with a through hole, and the first bracket is inserted through the through hole. In this way, the superimposed dimension of the bracket structure and the circuit board in the Z-axis direction can be reduced, so as to achieve the purpose of reducing the thickness of the electronic device, which is beneficial to realizing the thin and light design of the electronic device.

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.

[0083] The display screen 12 can be a flexible display screen or a rigid display screen. For example, the display screen 12 can be an organic light-emitting diode (OLED) display screen, a quantum dot light emitting diode (QLED) display screen, etc.

[0084] In order to enable external ambient light to pass through the screen 10 and shine on the under-screen functional devices such as the front camera module 40 and the light sensor 60 to ensure the light input of the under-screen functional devices, please refer to Figure 3 , Figure 3 For Figure 1 an enlarged view of the C part area in the illustrated electronic device. The screen 10 includes a display area 101 and a non-display area 102, and 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 for one week. It can be understood that in other embodiments, the non-display area 102 can also be located on the circumferential outer side of the display area 101.

[0085] In some embodiments, refer to Figure 3 , 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 contour shapes of the first light-transmitting area 102a and the second light-transmitting area 102b can be circular, oval, square, rectangular, etc.

[0086] Refer to Figure 4 , Figure 4 is Figure 1 a partial exploded view of the screen 10 in the electronic device 100 shown. A light-shielding layer 111 is provided on the surface of the light-transmitting cover plate 11 facing the display screen 12, and the light-shielding layer 111 can be an ink layer, a paint layer, etc. The area corresponding to the light-shielding layer 111 can be formed as the light-shielding area 102c.

[0087] In order to improve the light transmittance of the first light-transmitting area 102a and the second light-transmitting area 102b on the screen 10, refer to Figure 4 , the display screen 12 is provided with a first light-transmitting hole 123 and a second light-transmitting hole 124, and both the first light-transmitting hole 123 and the second light-transmitting hole 124 are through holes. That is, both the first light-transmitting hole 123 and the second light-transmitting hole 124 penetrate through 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 oval 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 shape 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 shape of the second light-transmitting area 102b.

[0088] Among them, the orthographic projection of the first light-transmitting hole 123 on the first reference plane can coincide with the orthographic projection of the first light-transmitting area 102a on the first reference plane, or the orthographic projection of the first light-transmitting hole 123 on the first reference plane can be located within the orthographic projection of the first light-transmitting area 102a on the first reference plane. Similarly, the orthographic projection of the second light-transmitting hole 124 on the first reference plane can coincide with the orthographic projection of the second light-transmitting area 102b on the first reference plane, or the orthographic projection of the second light-transmitting hole 124 on the first reference plane can be located within the orthographic projection of the second light-transmitting area 102b on the first reference plane. The first reference plane is perpendicular to the Z-axis direction.

[0089] In some embodiments, refer to Figure 3, the non-display area 102 can be strip-shaped. The outer contour of the non-display area 102 can be a racetrack shape, a rectangle, an ellipse, etc. The first light-transmitting area 102a and the second light-transmitting area 102b can be arranged at intervals in the length direction of the non-display area 102. Among them, the length direction of the non-display area 102 is perpendicular to the Z-axis direction. For example, in Figure 3 In the illustrated embodiment, the length 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 connection line between 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.

[0090] The housing 20 is used to protect the internal electronic components of the electronic device 100. Please refer 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 generally rectangular-annular. The light-transmitting cover plate 11 and the back cover 22 are both fixedly connected to the frame 211, and the light-transmitting cover plate 11, the back cover 22 and the frame 211 enclose an internal accommodation space of the electronic device 100, and the internal accommodation space can accommodate the display screen 12, the circuit board 30, the front camera module 40, etc.

[0091] The middle plate 212 is fixed to the inner surface of the frame 211 in a circle 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 can be used as a support skeleton of the electronic device 100, and the circuit board 30, the front camera module 40, etc. can be fixed to the middle plate 212.

[0092] The circuit board 30 is used to integrate electronic components. The circuit board 30 can be used to realize the electrical connection between various different electronic components inside the electronic device 100, and the circuit board 30 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 circuit board. The circuit board 30 can be fixed to the middle plate 212 by means of adhesion, snap connection, welding, screw connection, etc.

[0093] The electronic components include, but are not limited to, a processor. 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 processing unit (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 may be independent devices or integrated in one or more processors.

[0094] In addition, the electronic device 100 may further include an external memory interface, 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, a button, a rear camera module, etc., which are electrically connected to the processor.

[0095] The front camera module 40 is used for taking photos and videos. The front camera module 40 is disposed in the internal accommodation space of the electronic device 100 and is a type of under-screen functional device. Please refer to Figure 2 , the front camera module 40 has a light incident surface 40a, and the light incident surface 40a is opposite to the first light-transmitting region 102a. In this way, the scene light can enter the light incident surface 40a of the front camera module 40 through the first light-transmitting region 102a.

[0096] In some embodiments, the light incident surface 40a is exposed outside the first light-transmitting 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-transmitting 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-transmitting hole 123 on the first reference plane. Among them, the first reference plane is perpendicular to the Z-axis direction. In this way, it is possible to prevent the light incident surface 40a of the front camera module 40 from being blocked by the display screen 12, increase the light incident amount of the front camera module 40, and be beneficial to improving the shooting effect of the front camera module 40.

[0097] The front camera module 40 can be fixedly connected to the middle plate 212. In some embodiments, please refer to Figure 2The electronic device 100 includes a first bracket 511, and the front camera module 40 can be fixedly connected to the middle plate 212 by means of the first bracket 511. Specifically, during the assembly process, the first bracket 511 can be fixedly connected to the middle plate 212 first, 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, and the front camera module 40 can be prevented from colliding with the display screen 12 during the assembly process, thereby improving the assembly yield of the electronic device 100 and reducing the assembly difficulty of the front camera module 40.

[0098] Please continue reading Figure 2 The electronic device 100 further includes a light sensor 60, which can be electrically connected to the circuit board 30. The light sensor 60 refers to a device that can sensitively sense light energy from ultraviolet light to infrared light and convert the light energy into an electrical signal. The light sensor 60 is a sensing device, mainly composed of a photosensitive element. The light sensor 60 can be used to assist the front camera module 40 in shooting, so as to improve the shooting quality of the front camera module 40. In addition, the light sensor 60 can also be used to realize the automatic adjustment function of the screen 10.

[0099] The optical sensor 60 is a functional device under the screen. 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 can automatically identify the captured image through artificial intelligence and optimize the captured image in a targeted manner, bringing a better photo display effect. The anti-flicker light sensor can suppress the stroboscopic light generated when taking pictures. In indoor light, artificial light and other environments, it can accurately monitor the stroboscopic 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.

[0100] 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.

[0101] The light guide 52 is used to guide the external ambient light to the light sensing surface 60a of the light sensor 60. Figure 2, the light guide member 52 and the front camera module 40 are arranged in the first direction e1. Among them, the first direction e1 can be parallel to the length direction of the non-display area 102. That is to say, the first direction e1 is perpendicular to the Z-axis direction.

[0102] Please continue to refer to Figure 2 , the light guide member 52 includes a light incident surface 52a and a first light exit surface 52b. Among them, the light incident surface 52a faces the second light transmissive area 102b, the light exit surface faces the light sensor 60, and the light exit surface faces the photosensitive surface 60a of the light sensor 60. That is to say, the light sensor 60 is located on the side where the light exit surface of the light guide member 52 faces. In this way, the ambient light from the outside can enter the light guide member 52 through the light incident surface 52a of the light guide member 52, and under the guidance of the light guide member 52, it can be emitted through the first light exit surface 52b; the ambient light emitted through the first light exit surface 52b can be directed to the photosensitive surface 60a and be sensed by the light sensor 60, so as to direct more light to the light sensor 60, which can increase the light incident amount of the light sensor 60 and improve the accuracy of the light sensor 60 in collecting relevant parameters (light intensity, light frequency, color temperature, etc.) of the ambient light.

[0103] 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 exit surface 52b on the second reference plane. Further, the orthographic projection of the photosensitive surface 60a on the second reference plane can be located within the orthographic projection of the first light exit 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 exit surface 52b on the second reference plane. Among them, the second reference plane is perpendicular to the arrangement direction of the photosensitive surface 60a and the first light exit surface 52b. Exemplarily, the second reference plane is perpendicular to the Z-axis direction. In this way, the light incident amount of 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 the ambient light.

[0104] Please refer to Figure 2 , the light guide member 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 member 52 is fixedly connected to the second bracket 512. In this way, the light guide member 52 can be assembled to the middle plate 212 with the help of the second bracket 512.

[0105] Exemplarily, during assembly, the light guide member 52 can be first assembled to the second bracket 512, and then the second bracket 512 and the light guide member 52 as a whole can be assembled to the middle plate 212. Since the light guide member 52 usually needs to be manually assembled to the electronic device 100, by providing the second bracket 512, the assembly difficulty of the light guide member 52 can be reduced, so that the light incident surface 52a and the first light exit surface 52b of the light guide member 52 can be prevented from being contaminated by dust, fingerprints, etc. during the assembly process, and the assembly yield of the electronic device 100 can be improved.

[0106] In this embodiment, the second bracket 512 and the first bracket 511 need to be assembled to the middle plate 212 respectively. 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 arranged at intervals to reserve a clearance distance between the second bracket 512 and the first bracket 511. In this way, the distance between the light incident surface 52a of the light guide member 52 and the light incident surface 40a of the front camera module 40 in the first direction will be increased, thereby increasing the distance d between the first light transmission area 102a and the second light transmission area 102b. That is to say, the distance between the center of the first light transmission area 102a and the center of the second light transmission area 102b will be increased, resulting in an increase in 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.

[0107] It should be noted that the distance between two components described in the embodiments of the present application refers to the minimum distance between these two components. For example, the distance between the light incident surface 52a and the light incident surface 40a in the first direction refers to the minimum distance between the light incident surface 52a and the light incident surface 40a in the first direction. The distance between the first light transmission area 102a and the second light transmission area 102b refers to the minimum distance between the first light transmission area 102a and the second light transmission area 102b. For example, Figure 2 the distance d shown in

[0108] In order to reduce the area of the non-display area 102 in the screen 10 while ensuring the light incident amount of the under-screen functional device, please refer to Figures 5 - 6 , Figure 5 which is a partial perspective view of the electronic device 100 provided in some other embodiments of the present application, Figure 6 and Figure 5 is an exploded view of the electronic device 100 shown in

[0109] Specifically, please refer to Figures 7 - 8 , Figure 7 which is an assembled perspective view of the bracket structure 51, the light guide member 52 and the front camera module 40 in the electronic device 100 shown in Figure 5 , Figure 8 and Figure 7Exploded view of the shown assembly schematic diagram. 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 (i.e., 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 member 52.

[0110] In this way, by fixedly connecting the first bracket 511 to the second bracket 512, during assembly, the first bracket 511 and the second bracket 512 can be integrally assembled to the housing 20 of the electronic device 100. For example, at least one of the light guide member 52 and the front camera module 40 can be first assembled to the bracket structure 51 to form a bracket module, and then the bracket module can be integrally assembled to the housing 20 of the electronic device 100. Or, the bracket structure 51 can be first assembled to the housing 20 of the electronic device 100, and then the front camera module 40 and the light guide member 52 can be respectively assembled to the housing 20, which can avoid interference between the first bracket 511 and the second bracket 512 during the assembly process, and there is no need to reserve an avoidance space between the first bracket 511 and the second bracket 512.

[0111] Thus, on the one hand, the distance between the light incident surface 52a of the light guide member 52 and the light incident surface 40a of the front camera module 40 can be reduced, so that the distance between the center of the first light transmission area 102a and the center of the second light transmission area 102b can be reduced, which is beneficial to reducing the area of the non-display area 102 of the screen 10, and further beneficial to improving the screen-to-body ratio of the electronic device 100; on the other hand, the size of the bracket structure 51 in the first direction e1 can be reduced, the structural redundancy can be reduced, the occupied space of the bracket structure 51 can be reduced, the structure of the electronic device 100 can be made more compact, the structural layout of the electronic device 100 can be optimized, and it is beneficial to realize the miniaturized design of the electronic device 100. In addition, for the electronic device 100 in this embodiment, even if only one front camera module 40 is provided, the appearance effect of a front dual camera can be achieved.

[0112] In some embodiments, the first bracket 511 and the second bracket 512 are an integral structural member. For example, the first bracket 511 and the second bracket 512 can be processed by injection molding processes (including single injection molding, secondary injection molding, metal insert injection molding, etc.), metal powder injection molding technology (MIM), stamping, hot forging and other processes.

[0113] 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, 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 member 52 and the front camera module 40, improving the assembly accuracy of the light guide member 52 and the front camera module 40, and further improving the concentricity between the light incident surface 40a of the front camera module 40 and the first light transmission region 102a, as well as the concentricity between the light incident surface 52a of the light guide member 52 and the second light transmission region 102b, reducing or eliminating appearance eccentricity, improving the aesthetic appearance of the electronic device 100 while ensuring the light incident amount of the front camera module 40 and the light guide member 52. On the other hand, the assembly steps of the electronic device 100 can be reduced, the assembly difficulty can be lowered, the assembly man-hours can be saved, the assembly efficiency can be improved, and the cost can be reduced.

[0114] It can be understood that in other embodiments, the first bracket 511 and the second bracket 512 can also be fixedly connected by means of bonding, welding, clamping, screw connection, etc.

[0115] Please refer to Figures 8 - 9 , Figure 9 for Figure 5 a perspective view of the bracket structure 51 in the electronic device 100 shown. The first bracket 511 includes a first top plate 5111 and a first side wall 5112. The first top plate 5111 is in the shape of a plate. Exemplarily, the first top plate 5111 can be a polygon such as a rectangle, a trapezoid, etc., or can be a circle, an ellipse, an irregular shape, etc. A first through hole 5111c is provided on the first top plate 5111. Specifically, please refer to Figure 8 and in combination with Figure 9 , the first top plate 5111 includes a first outer surface 5111a and a first inner surface 5111b that face away from each other in its thickness direction (such as Figure 8 the Z-axis direction in

[0116] ). The first outer surface 5111a can face the display screen 12. The first through hole 5111c penetrates 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 oval hole, a square hole, etc. In some embodiments, the material of the first top plate 5111 can be metal. Exemplarily, the material of the first top plate 5111 can be stainless steel, aluminum alloy, magnesium alloy, titanium alloy, etc. In this way, while reducing the thickness of the first top plate 5111, the overall structural strength of the bracket structure 51 can be improved, and the occupied space can be reduced. In addition, when the front camera module 40 is a telephoto camera module or a zoom camera module, after reducing the thickness of the first top plate 5111, it is also beneficial to increase the focal length and zoom range of the front camera module 40, which is beneficial to improving the performance of the front camera module 40.

[0117] Of course, the material of the first top plate 5111 is not limited to this. For example, in other embodiments, the material of the first top plate 5111 can be plastic.

[0118] The first side wall 5112 is of a frame structure. In some embodiments, referring to Figure 9 , the first side wall 5112 can be an annular frame structure. In this embodiment, the first side wall 5112 can be generally a rectangular annular frame. It can be understood that in other embodiments, the first side wall 5112 can also be generally a circular annular frame, an elliptical annular frame, etc.

[0119] The first side wall 5112 is fixedly connected to the first top plate 5111 and extends along the circumference of the first top plate 5111. A first receiving cavity 5113 is defined between the first side wall 5112 and the first top plate 5111, and the first through hole 5111c communicates with the first receiving cavity 5113. The first receiving cavity 5113 has a first open end 5113a, and the first open end 5113a faces the first top plate 5111.

[0120] The material of the first side wall 5112 can be plastic, rubber, etc. In this way, the material cost of the bracket structure 51 can be reduced, the weight of the bracket structure 51 can be reduced, and the wear resistance of the bracket structure 51 can be improved.

[0121] In some embodiments, referring to Figure 9 , the first side wall 5112 includes a first side plate 5112a, a second side plate 5112b, a third side plate 5112c, and a fourth side plate 5112d. The first side plate 5112a and the second side plate 5112b are disposed opposite to each other, and the first side plate 5112a and the second side plate 5112b are respectively fixedly connected to both sides of the first top plate 5111. Exemplarily, the first side plate 5112a and the second side plate 5112b can be disposed opposite to each other in the first direction e1. The first side plate 5112a can be generally formed as a flat plate. The second side plate 5112b can be generally formed as a flat plate, an arc-shaped plate, etc.

[0122] The third side plate 5112c and the fourth side plate 5112d are oppositely arranged, and the third side plate 5112c and the fourth side plate 5112d are respectively fixedly connected to both sides of the first top plate 5111. Exemplarily, the third side plate 5112c and the fourth side plate 5112d can be oppositely arranged in the second direction e2. Wherein, 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 enclosure 5112 can be formed by sequentially connecting the first side plate 5112a, the third side plate 5112c, the second side plate 5112b, and the fourth side plate 5112d. The third side plate 5112c and the fourth side plate 5112d can be formed into a flat plate, an arc plate, etc.

[0123] It can be understood that the first side enclosure 5112 can be an integral structural member, or can be assembled and formed by multiple parts through bonding, snap connection, threaded connection, etc. Additionally, in other embodiments, the first side enclosure 5112 can also be a non-circular frame. In this case, the first side enclosure 5112 may not include at least one of the third side plate 5112c and the fourth side plate 5112d.

[0124] In some embodiments, for the convenience of realizing the connection between the first top plate 5111 and the first side enclosure 5112, please refer to Figure 10a and Figure 10b , Figure 10a is Figure 9 the exploded view of the bracket structure 51 shown in Figure 10b is Figure 9 the cross-sectional view of the bracket structure 51 shown in at line B-B. The first bracket 511 includes a metal part 5110. The metal part 5110 includes the above-mentioned first top plate 5111 and a flanging part 5114. The flanging part 5114 is connected to the edge of the first top plate 5111 and is folded towards the direction away from the first outer surface 5111a. In some embodiments, the first top plate 5111 and the flanging part 5114 can be an integral structure.

[0125] The flanging part 5114 is used to be fixed to the first side enclosure 5112. Specifically, please refer to Figure 10b , at least part of the flanging part 5114 can be embedded in the first side enclosure 5112. Exemplarily, the metal part 5110 and the first side enclosure 5112 can be connected as a whole through the metal insert injection molding process. In this way, the processing technology of the first top plate 5111 and the first side enclosure 5112 can be simplified, and the connection reliability between the first top plate 5111 and the first side enclosure 5112 can be improved.

[0126] On this basis, in order to further improve the connection reliability between the first top plate 5111 and the first side enclosure 5112, please refer to Figure 10a, a plurality of embedding grooves 5114a are formed at the end of the flanging part 5114 away from the first top plate 5111. The embedding grooves 5114a can penetrate through the two opposite side surfaces of the flanging part 5114 in its thickness direction, as well as the end surface of the flanging part 5114 away from the first top plate 5111. In this way, it is beneficial to increase the connection area between the flanging part 5114 and the first side wall panel 5112, thereby improving the connection reliability between the first top plate 5111 and the first side wall panel 5112, and the structure is simple and the processing is convenient.

[0127] Please refer to Figure 11 , Figure 11 is Figure 7 a cross-sectional view of the assembled three-dimensional view shown in the figure at the C-C line. The front camera module 40 includes a housing 41, a lens 42, etc. The lens 42 is disposed in the housing 41.

For example, the housing 41 can be fixedly connected to the first side wall panel 5112 of the first bracket 511 by means of snap connection, bonding, etc.

[0128] The lens 42 has a light incident surface 40a and a second light exit surface 40b. That is, the light incident surface 40a of the front camera module 40 is formed on the lens 42. Scenery light enters the lens 42 through the light incident surface 40a and exits through the second light exit surface 40b. The lens 42 can be a telephoto lens, a zoom lens, a wide-angle lens, etc. That is, the front camera module 40 can be a telephoto camera module, a zoom camera module or a wide-angle camera module.

[0129] Please refer to Figure 11 , the front camera module 40 is fixedly connected to the first bracket 511. The front camera module 40 is located on the circumferential inner side of the first side wall panel 5112. Specifically, a part of the front camera module 40 is located in the first accommodation cavity 5113, and the outer contour shape of the housing 41 can be adapted to the shape of the inner wall surface of the first accommodation cavity 5113. The lens 42 of the front camera module 40 can pass through the first through hole 5111c.

[0130] In some embodiments, please refer to Figure 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 arranged around the first through hole 5111c for one week. The first buffer member 54 can play a role of buffering and protecting, and can also play a role of waterproofing and dustproofing. Exemplarily, the first buffer member 54 can be a foam.

[0131] Please refer to Figure 8 and Figure 9, the second bracket 512 includes a second top plate 5121, second side enclosing plates 5122, and a light-shielding cylinder 5123. The second top plate 5121 is generally plate-shaped. The thickness direction of the second top plate 5121 is parallel to the thickness direction of the first top plate 5111. A second through hole 5121c is provided on the second top plate 5121.

[0132] Specifically, please refer to Figure 8 and combine with Figure 9 , the second top plate 5121 includes a second outer surface 5121a and a second inner surface 5121b that face away from each other in its thickness direction (for example, Figure 9 the Z-axis direction in ). The second through hole 5121c penetrates through the second outer surface 5121a and the second inner surface 5121b. Among them, the second outer surface 5121a can face the display screen 12. The second through hole 5121c can be formed as a circular hole, an oval hole, a square hole, etc.

[0133] Please continue to refer to Figure 8 and combine with Figure 9 , the light-shielding cylinder 5123 is fixedly connected to the second top plate 5121. The light-shielding cylinder 5123 is formed as a cylindrical structure with both ends open. The light-shielding cylinder 5123 is disposed around the second through hole 5121c and protrudes from the second outer surface 5121a of the second top plate 5121. The light-shielding cylinder 5123 can be coaxially disposed with the second through hole 5121c. That is, the central axis of the light-shielding cylinder 5123 and the central axis of the second through hole 5121c can be substantially coincident. In some embodiments, the light-shielding cylinder 5123 and the second top plate 5121 are an integral structure. Exemplarily, the light-shielding cylinder 5123 and the second top plate 5121 can be integrally injection-molded, with simple process and convenient processing.

[0134] In some embodiments, please refer to Figure 9 and Figure 10a , the second side enclosing plates 5122 are annular frame structures. The outer contour of the second side enclosing plates 5122 can be a polygon, a circle, an ellipse, an irregular figure, etc. The second side enclosing plates 5122 are fixedly connected to the second top plate 5121 and extend along the circumferential direction of the second top plate 5121. A second accommodation cavity 5124 can be defined between the second side enclosing plates 5122 and the second top plate 5121. Exemplarily, the second side enclosing plates 5122 can be disposed around the edge of the second top plate 5121.

[0135] Please refer to Figures 9 - 10a, the second side wall panel 5122 includes a first extension section 5122a and a second extension section 5122b, and the first extension section 5122a and the second extension section 5122b are arranged in the circumferential direction of the second top plate 5121. The first extension section 5122a can extend along a straight line. The second extension section 5122b can include a plurality of first sub-panel segments, and the plurality of first sub-panel segments are arranged in the circumferential direction of the second top plate 5121, and two adjacent first sub-panel segments are connected. The two ends of the second extension section 5122b in the circumferential direction of the second top plate 5121 can be respectively connected to the two ends of the first extension section 5122a in the circumferential direction of the second top plate 5121.

[0136] Please refer to Figure 10b , the second side wall panel 5122 of the second bracket 512 can be fixedly connected to the first side wall panel 5112 of the first bracket 511. In some embodiments, the second side wall panel 5122 can be fixedly connected to the first side plate 5112a of the first side wall panel 5112 by means of the first extension section 5122a. Exemplarily, the outer wall surface of the second side wall panel 5122 can be fixedly connected to the outer wall surface of the first side wall panel. In this way, it is convenient to fixedly connect the first bracket 511 and the second bracket 512 into a whole, which is beneficial to increasing the connection area between the first bracket 511 and the second bracket 512 and can improve the connection reliability between the first bracket 511 and the second bracket 512.

[0137] Among them, please refer to Figure 10b , the outer wall surface of the first side wall panel 5112 refers to the wall surface of the first side wall panel 5112 that is away from the central axis O1 of the first through hole 5111c, and the outer wall surface of the second side wall panel 5122 refers to the wall surface of the second side wall panel 5122 that is away from the central axis O2 of the second through hole 5121c.

[0138] In some embodiments, a part of the outer wall surface of the second side wall panel 5122 is attached to a part of the outer wall surface of the first side wall panel 5112. Specifically, please refer to Figure 10b , the outer wall surface of the first extension section 5122a can be attached to the outer wall surface of the first side plate 5112a. In this way, the structural redundancy of the bracket structure 51 can be reduced, making the structure of the bracket structure 51 more compact. On the one hand, the size of the bracket structure 51 in the arrangement direction of the first bracket 511 and the second bracket 512 can be further reduced, so that 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, the area of the non-display area 102 in the screen 10 can be reduced, and the screen ratio of the screen 10 can be improved; on the other hand, the overall occupied space of the bracket structure 51 can be further reduced, which is convenient for the assembly of the bracket structure 51, the light guide member 52 and the front camera module 40 in the electronic device 100 with limited space, and is beneficial to the realization of the miniaturized design of the electronic device 100.

[0139] Exemplarily, the first extension segment 5122a and the first side plate 5112a can be integrally connected by an injection molding process. Specifically, the first bracket 511 and the second bracket 512 can be separately processed and formed, and then integrally connected by an injection molding process, so that the outer wall surface of the first extension segment 5122a is attached to the outer wall surface of the first side plate 5112a. Alternatively, the first side enclosure plate 5112 and the second side enclosure plate 5122 can also be directly integrally processed by an injection molding process. In this way, the first extension segment 5122a and the first side plate 5112a can be formed into an integral structural member, that is, the first bracket 511 and the second bracket 512 can share the same wall plate, which can not only reduce the structural redundancy of the bracket structure 51 and reduce the size of the bracket structure 51 in the arrangement direction of the first bracket 511 and the second bracket 512, but also improve the connection reliability between the first side enclosure plate 5112 and the second side enclosure plate 5122, and can simplify the processing technology of the bracket structure 51, omit the assembly process of the bracket structure 51, and improve the production efficiency of the bracket structure 51.

[0140] Please refer to Figures 12 - 13 , Figure 12 is Figure 6 the perspective view of the light guide member 52 in the electronic device 100 shown in Figure 13 is Figure 12 the cross-sectional view of the light guide member 52 shown in at line D-D. The light guide member 52 includes a light guide column 521 and a fixed seat 522. The light guide column 521 is fixedly connected to the fixed seat 522. In some embodiments, the light incident surface 52a can be formed on the surface of the light guide column 521 facing away from the fixed seat 522, and the first light emitting surface 52b can be formed on the surface of the fixed seat 522 facing away from the light guide column 521. It can be understood that in other embodiments, the light incident surface 52a can also be formed on other surfaces of the light guide column 521. Similarly, the first light emitting surface 52b can be formed on other surfaces of the fixed seat 522, or the first light emitting surface 52b can also be formed on the light guide column 521.

[0141] In some embodiments, the area of the first light emitting surface 52b is larger than the area of the light incident surface 52a. In this way, it is beneficial to increase the overlapping area of the first light emitting surface 52b and the photosensitive surface 60a of the light sensor 60 on the second reference plane, which can increase the light incident amount of the light sensor 60. At the same time, it is beneficial to reduce the area of the second light transmissive region 102b corresponding to the light incident surface 52a, which is beneficial to reduce the area of the non-display region 102 of the screen 10 and improve the screen-to-body ratio of the screen 10. Thus, the light incident amount of the light sensor 60 and the area of the non-display region 102 can be taken into account simultaneously.

[0142] Specifically, please refer to Figures 12 - 13, the light guide column 521 is in the shape of a long 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 away from the light inlet surface 52a. The light guide column 521 can be fixedly connected to the fixing seat 522 through the second light guide segment 5212.

[0143] See also Figures 12 - 13 , in the direction from the first light guide segment 5211 to the second light guide segment 5212, the cross-sectional area of ​​the second light guide segment 5212 gradually increases. Exemplarily, the second light guide portion may be roughly in the shape of a truncated cone, a prism, etc. In this case, in the direction from the first light guide segment 5211 to the second light guide segment 5212, the cross-sectional area of ​​the first light guide segment 5211 may remain unchanged. Exemplarily, the first light guide segment 5211 may be in the shape of a cylinder, a prism, etc.

[0144] In this way, the external ambient light enters the first light guide segment 5211 from the light-incoming 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 is beneficial to increase the area of ​​the first light-exiting 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-incoming surface 52a can be reduced, thereby reducing the area of ​​the second light-transmitting area 102b corresponding to the light-incoming surface 52a, thereby helping to reduce the area of ​​the non-display area 102 in the screen 10 and improving the screen-to-body ratio of the screen 10.

[0145] It is understandable that in other embodiments, the cross-sectional area of ​​the first light guide segment 5211 may also gradually increase in the direction from the first light guide segment 5211 to the second light guide segment 5212. In this way, the area of ​​the second light emitting surface 40b can be increased while the area of ​​the light entering surface 52a can be reduced.

[0146] The fixing base 522 can be roughly in the shape of a flat plate. Figure 13 The fixing seat 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 used for fixedly connecting to the light guide column 521, and the skirt portion 5222 is used for fixedly connecting to the second bracket 512.

[0147] 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 (for example Figure 13in the Z-axis direction). In this way, the skirt portion 5222 can be located on the circumferential outer side of the light guide column 521, and a stepped surface can be formed between the light guide column 521 and the fixed seat 522, facilitating the fixation of the light guide member 52 to the second bracket 512.

[0148] The light guide member 52 can be processed from a light-transmitting material such as glass or plastic. In this way, the light transmittance of the light guide member 52 can be ensured, thereby ensuring the light incident amount of the light sensor 60 and improving the detection accuracy of the light sensor 60.

[0149] On this basis, in order to further improve the light transmittance of the light guide member 52, please refer to Figures 12 - 13 , a light homogenizing film 523 is provided on the first light-emitting surface 52b of the light guide member 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 adhered to the first light-emitting surface 52b. The material of the light homogenizing film 523 includes but is not limited to polyethylene terephthalate (PET).

[0150] In some embodiments, the light guide column 521 and the fixed seat 522 can be an integral structural member. For example, the light guide member 52 is processed into an integrally formed part by an injection molding process. In this way, it is beneficial to improve the connection strength between the light guide column 521 and the fixed seat 522, and can simplify the processing process of the light guide member 52 and reduce the processing cost of the light guide member 52.

[0151] In some embodiments, please refer to Figure 11 , the light guide member 52 can be located on the circumferential inner side of the second side wall panel 5122. The light guide column 521 of the light guide member 52 can be disposed in the light-shielding cylinder 5123. The light-shielding cylinder 5123 can play a role in light shielding, avoiding lateral leakage of light in the circumferential direction of the light guide column 521. One end of the light-shielding cylinder 5123 away from the second top plate 5121 has a first cylinder opening 5123a, and the light incident surface 52a of the light guide member 52 is exposed outside the first cylinder opening 5123a. In this way, when looking at the first top plate 5111 from the light-shielding cylinder 5123, the light incident surface 52a of the light guide member 52 can be seen from the first cylinder opening 5123a.

[0152] Specifically, the light guide column 521 can be entirely located in the light-shielding cylinder 5123. Or, a part of the light guide member 52 can be disposed in the light-shielding cylinder 5123. In this case, a part of the light guide column 521 can penetrate out of the first cylinder opening 5123a to the outside of the light-shielding cylinder 5123. That is, a part of the light guide column 521 is located on the side of the light-shielding cylinder 5123 away from the first top plate 5111. As long as it can be ensured that the light incident surface 52a can be seen from the first cylinder opening 5123a of the light-shielding cylinder 5123.

[0153] Please continue to refer to Figure 11, the light guide member 52 can be fixed to the second top plate 5121 by means of 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. Exemplarily, the skirt portion 5222 can be connected to the second inner surface 5121b of the second top plate 5121 by means of adhesion, welding, snap connection, screw connection, riveting, etc.

[0154] It can be understood that in other embodiments, the fixing base 522 can also be fixedly connected to the second side panel 5122.

[0155] In some embodiments, in order to further reduce the distance between the light incident surface 52a of the light guide member 52 and the light incident surface 40a of the front camera module 40, please refer to Figure 11 and in combination with Figure 13 , in the first direction e1, the maximum dimension by which the fixing base 522 protrudes from the light guide column 521 in the direction away from the first bracket 511 is the first dimension d1, and the maximum dimension by which the fixing base 522 protrudes from the light guide column 521 in the direction close to the first bracket 511 is the second dimension d2, and 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, and further the distance between the light incident surface 52a of the light guide member 52 and the light incident surface 40a of the front camera module 40 can be reduced. Thus, the distance between the center of the first light transmission region 102a and the center of the second light transmission region 102b can be further reduced, achieving the purpose of reducing the area of the non-display region 102 and increasing the screen-to-body ratio of the screen 10. In addition, when the first bracket 511 includes a metal member 5110, setting the first dimension d1 to be greater than the second dimension d2 can also prevent the fixing base 522 from interfering with the flanging portion 5114 of the metal member 5110.

[0156] Specifically, in some embodiments, please refer to Figure 12 , the skirt portion 5222 is in an open-ring shape, and in the first direction e1, the skirt portion 5222 is located on the side of the light guide column 521 away from the first bracket 511. That is, no skirt portion 5222 is provided on the side of the light guide column 521 close to the first bracket 511. The skirt portion 5222 is generally in a C shape. In this way, it can be ensured that the first dimension d1 is greater than the second dimension d2, and the structure is simple and convenient for processing.

[0157] It can be understood that in other embodiments, in the first direction e1, skirt portions 5222 can be provided on both the side of the light guide column 521 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 dimension of the skirt portion 5222 on the side of the light guide column 521 away from the first bracket 511 is greater than the dimension of the skirt portion 5222 on the side of the light guide column 521 close to the first bracket 511.

[0158] Based on any of the above embodiments, please refer to Figure 10b and in combination with Figure 11 , a part of the second inner surface 5121b of the second top plate 5121 is recessed towards the second outer surface 5121a to form a recessed groove 5121d, and the recessed groove 5121d penetrates the hole wall surface of the second through hole 5121c. The skirt portion 5222 is received and fixed in the recessed groove 5121d. In this way, the superimposed dimension of the second top plate 5121 and the fixed seat 522 in the Z-axis direction can be reduced, so that the occupied space of the second bracket 512 and the light guide member 52 in the Z-axis direction can be reduced, which is beneficial to reducing the thickness of the electronic device 100 and realizing the thin and light design of the electronic device 100.

[0159] Please refer to Figure 14 and in combination with Figure 15 , Figure 14 is Figure 5 a partial assembly schematic diagram of the middle frame 21 and the screen 10 in the electronic device 100 shown, Figure 15 is Figure 5 a cross-sectional view of the electronic device 100 shown at the E-E line. The middle plate 212 includes a first surface 212a and a second surface 212b facing away from each other. Among them, 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.

[0160] The middle plate 212 is provided with a first avoidance hole 2121 and a second avoidance hole 2122. Specifically, both the first avoidance hole 2121 and the second avoidance hole 2122 are through holes. That is to say, both the first avoidance hole 2121 and the second avoidance hole 2122 penetrate the first surface 212a and the second surface 212b. The first avoidance hole 2121 and the second avoidance hole 2122 can be formed into circular holes, oval holes, square holes, etc. The shape of the first avoidance hole 2121 and the shape of the second avoidance hole 2122 can be the same or different.

[0161] Please refer to Figure 15 , the first avoidance hole 2121 can be opposite to the first light-transmitting area 102a, and the second avoidance hole 2122 can be opposite to 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 outside the first avoidance hole 2121, and the light-incident surface 52a of the light guide member 52 is exposed outside the second avoidance hole 2122.

[0162] Specifically, in some embodiments, the positive projection of the light incident surface 40a on the first reference plane is located within the positive projection of the first avoidance hole 2121 on the first reference plane, or the positive projection of the light incident surface 40a on the first reference plane coincides with the positive 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.

[0163] Similarly, the positive projection of the light incident surface 52a on the first reference plane is located within the positive projection of the second avoidance hole 2122 on the first reference plane, or the positive projection of the light incident surface 52a on the first reference plane coincides with the positive projection of the second avoidance hole 2122 on the first reference plane. In this way, the entire light incident surface 52a can be exposed outside the second avoidance hole 2122.

[0164] In this way, it is possible to prevent the light incident surface 40a of the front camera module 40 and the light incident surface 52a of the light guide member 52 from being blocked by the middle plate 212, so that the ambient light energy from the outside can enter the front camera module 40 through the first light transmission region 102a and can enter the light guide member 52 through the second light transmission region 102b.

[0165] In some embodiments, please refer to Figures 14 - 15 , a part of the first surface 212a of the middle plate 212 is recessed towards the second surface 212b to form a sunken groove 2123. Specifically, a part of the bracket structure 51 can be accommodated and fixed in the sunken groove 2123, and the other part is located outside the sunken groove 2123. Or, the bracket structure 51 can be entirely accommodated and fixed in the sunken groove 2123. In this way, the overlapping dimension of the bracket structure 51 and the middle plate 212 in the Z-axis direction can be reduced, the thickness of the electronic device 100 can be reduced, and the thin and light design of the electronic device 100 can be realized.

[0166] In some embodiments, please refer to Figures 14 - 15 , the bracket structure 51 can be adhesively fixed to the sunken groove 2123 through a first adhesive member 53. The first adhesive member 53 can be a double-sided tape, a hot melt adhesive, etc. The structure is simple and the assembly is convenient.

[0167] Exemplarily, please refer to Figure 14 , the first adhesive member 53 is disposed around the perimeter of the first avoidance hole 2121 and around the perimeter of the second avoidance hole 2122. In this way, a sealed connection between the bracket structure 51 and the middle plate 212 can be achieved through the first adhesive member 53, and it is possible to prevent dust, liquid, etc. from entering the interior of the electronic device 100 from the first avoidance hole 2121 and the second avoidance hole 2122, and the waterproof and dustproof performance of the electronic device 100 can be improved.

[0168] It can be understood that in other embodiments, the middle plate 212 may not be provided with the above-mentioned sunken groove 2123.

[0169] To further reduce the thickness of the electronic device 100, please refer to Figure 15 , a through hole 31 is provided on the circuit board 30, and the first bracket 511 is inserted through the through hole 31. In this way, the overlapping dimension of the bracket structure 51 and the circuit board 30 in the Z-axis direction can be reduced, so as to achieve the purpose of reducing the thickness of the electronic device 100, which is beneficial to realizing the thin and light design of the electronic device 100.

[0170] In some embodiments, please continue to refer to Figure 15 , a seal 55 is provided between the second bracket 512 and the circuit board 30. The second bracket 512 is hermetically connected to the circuit board 30 through the seal 55. The seal 55 can be fixedly connected to the end face of the second side wall 5122 facing away from the light-shielding cylinder 5123. The seal 55 and the second side wall 5122 can be fixed by bonding, snap connection or other means.

[0171] Please refer to Figure 15 and combine with Figure 16 , Figure 16 For Figure 7 the assembly schematic diagram of the bracket structure 51, the light guide member 52, the first buffer member 54, and the seal 55 shown. The seal 55 can be annular. The photosensor 60 can be arranged on the inner circumference of the seal 55. In this way, the waterproof and dustproof performance of the photosensor 60 can be improved, dust, water vapor, liquid, etc. can be avoided from damaging the photosensor 60, and the reliability of the photosensor 60 can be improved.

[0172] In some embodiments, the seal 55 can be foam. In this way, not only can the seal 55 play a sealing role, but also can play a buffering and protecting role, can reduce the stress between the second bracket 512 and the circuit board 30, and thus can improve the reliability of the circuit board 30.

[0173] In order to improve the assembly accuracy of the bracket structure 51 and the middle frame 21, so as to further improve the concentricity of the light incident surface 40a of the front camera module 40 and the first light transmission area 102a, and the concentricity of the light incident surface 52a of the light guide member 52 and the second light transmission area 102b, and reduce or eliminate the appearance eccentricity, the bracket structure 51 and the middle frame 21 are assembled through an automated device (not shown in the figure). The automated device can include an image capturing device. The image capturing device can be a CCD camera (charge-coupled device). In this case, the automated device can also be called a CCD device.

[0174] During assembly, the positioning features on the middle frame 21 and the positioning features on the bracket structure 51 can be identified by an image capture device to assemble the bracket structure 51 to the corresponding position on the middle frame 21. Among them, the principle of the image capture device to identify the positioning features on the middle frame 21 is as follows: The positioning features of structural components (such as the middle frame 21, the bracket structure 51, etc.) have different light reflectance rates from other structures of the structural components, and thus the identification of the positioning features can be achieved. That is to say, the light reflection degrees of the positioning features of the structural components and other structures of the structural components are different. Among them, the light reflectance rate refers to the ability of an object to reflect light.

[0175] In some embodiments, in order to reduce the assembly difficulty of the electronic device 100, the light guide member 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 together by an automated device.

[0176] Since the second through hole 5121c on the bracket structure 51 is blocked by the light guide member 52 after the light guide member 52 is assembled to the bracket structure 51 and cannot be identified by the image capture device. In this case, in order to achieve the automated assembly of the bracket structure 51 and the middle frame 21, please refer to Figure 16 , a marking hole 5121e is provided on the second bracket 512, and the marking hole 5121e penetrates through the second top plate 5121 of the second bracket 512. The shape of the marking hole 5121e can be circular, oval, polygonal, etc. In this way, during assembly, the center a of the first through hole 5111c and the center b of the marking hole 5121e can be identified (also referred to as grabbed), and the line segment L1 connecting the center a of the first through hole 5111c and the center b of the marking hole 5121e can be fitted, and the line segment L1 is used as the positioning feature on the bracket module to achieve the overall automated assembly of the bracket structure 51 and the light guide member 52.

[0177] Specifically, please refer to Figure 17 , Figure 17 For Figure 5 the assembly flow chart of the bracket structure 51, the light guide member 52 and the middle frame 21 of the electronic device 100 shown. The assembly method of the electronic device 100 includes:

[0178] Step S100: Provide the middle frame 21, grab the center c of the first avoidance hole 2121 and the center d of the second avoidance hole 2122 on the middle frame 21 by an image capture device, and fit the line segment L2 connecting the center c of the first avoidance hole 2121 and the center d of the second avoidance hole 2122; among them, the included 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 the first angle; exemplarily, the first angle can be 90 degrees, 75 degrees, 60 degrees, 45 degrees, 30 degrees, 15 degrees, 0 degrees, etc.;

[0179] Specifically, the automated device further 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.).

[0180] It should be noted that the "included angle" mentioned in the embodiments of the present application refers to the minimum angle between two straight lines or two line segments. Additionally, in some embodiments, in the assembly method of the electronic device 100, before step S100, it may further include 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 fixed to the assembly fixture together.

[0181] Step S200: Provide a bracket module 50. The bracket module 50 includes a bracket structure 51 and a light guide member 52 fixedly connected to the bracket structure 51. Capture the center a of the first through hole 5111c and the center b of the identification hole through an image capture device, and fit a line segment L1 connecting the center a of the first through hole 5111c and the center b of the identification hole.

[0182] In some embodiments, in order to further improve the assembly efficiency, reduce the assembly process and assembly man-hours, the bracket module 50 further includes a first buffer member 54 and a seal member 55.

[0183] Step S300: Align the center a of the first through hole 5111c with the center c of the first avoidance hole 2121 to make the center a of the first through hole 5111c coincide with the center c of the first avoidance hole 2121, and then rotate the bracket module 50 so that the included angle between the line segment L2 and the line segment L1 is a first angle.

[0184] In this way, the automated assembly of the bracket module 50 and the middle frame 21 can be achieved. On the one hand, it can improve the assembly accuracy of the bracket module 50 and the middle frame 21, thereby improving 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 member 52 and the second light-transmitting area 102b, reducing or eliminating appearance eccentricity, and improving the appearance aesthetics of the electronic device 100 while ensuring the light incident amount of the front camera module 40 and the light guide member 52. On the other hand, it can reduce the assembly difficulty of the electronic device 100, reduce the assembly man-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, during the subsequent assembly of the front camera module 40, it can also prevent the front camera module 40 from colliding with the display screen 12, thereby avoiding damage to the display screen 12 caused by collision, and improving the assembly yield of the electronic device 100.

[0185] Specifically, the automated device further includes a robotic arm. During assembly, the robotic arm can grasp the bracket module 50 and assemble the bracket module 50 to the assembly position on the middle frame 21. Exemplarily, the robotic arm may include a suction head. Please refer to Figure 17 Steps S200 and S300 in. The bracket module 50 includes an adsorption film 56. The adsorption film 56 is fixedly connected to the first side wall 5112, and the adsorption film 56 is disposed opposite to the first top plate 5111. The robotic arm can grasp the bracket module 50 by adsorbing and cooperating 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 the front camera module 40 is assembled, the adsorption film 56 can be torn off.

[0186] 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 a transparent structure. To facilitate the distinction of the adsorption film 56, Figure 17 The adsorption film 56 in is shown by a dotted line.

[0187] In some embodiments, to facilitate the adsorption and cooperation between the suction head and the adsorption film 56, the adsorption film 56 is a rigid film. Exemplarily, the adsorption film 56 can be processed from rigid plastic.

[0188] In some embodiments, the orthographic projection of the first accommodation cavity 5113 on the first reference plane is located within the orthographic projection of the adsorption film 56 on the first reference plane. In this way, the adsorption film 56 can block the open mouth of the first accommodation cavity 5113, prevent dust, liquid, etc. from entering the first cavity, and play a role in dust prevention and waterproofing.

[0189] To facilitate tearing off the adsorption film 56 from the bracket module 50 in subsequent processes, please refer to Figure 17 Steps S200 in. The adsorption film 56 includes an adsorption portion 561 and a first tearing portion 562. The adsorption portion 561 is fixedly connected to the first side wall 5112, and the first tearing portion 562 is fixedly connected to the adsorption portion 561 and is located outside the circumferential direction of the first side wall 5112. In this way, the first tearing portion 562 can protrude from the outer wall surface of the first side wall 5112, reducing the difficulty of tearing off the adsorption film 56.

[0190] In some embodiments, to further ensure the assembly yield of the electronic device 100, the assembly method of the electronic device 100 further includes an inspection step (which can also be called a recheck step). Through the inspection step, it can be determined whether the bracket module 50 is assembled in place.

[0191] Specifically, please refer to Figure 17In step S300, 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 included angle between the first identification straight edge L4 and the second identification straight edge L5 is the second angle. Exemplarily, the second angle can be 90 degrees, 75 degrees, 60 degrees, 45 degrees, 30 degrees, 15 degrees, 0 degrees, etc.

[0192] After assembling the bracket module 50 to the middle frame 21, the assembling method of the electronic device 100 further includes:

[0193] Step S400: Grab 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 coincides with the center c of the first avoidance hole 2121;

[0194] Step S500: Grab the first identification straight edge L4 and the second identification straight edge L5, and determine whether the included angle between the first identification straight edge L4 and the second identification straight edge L5 is the second angle.

[0195] When the center a of the first through hole 5111c coincides with the center c of the first avoidance hole 2121 and the included angle between the first identification straight edge L4 and the second identification straight edge L5 is the second included angle, it is confirmed that the bracket module 50 is assembled in place. When the center a of the first through hole 5111c does not coincide with the center c of the first avoidance hole 2121, or the included angle between the first identification straight edge L4 and the second identification straight edge L5 is not the second included angle, it is confirmed that the bracket module 50 is not assembled in place.

[0196] Among them, the order of step S400 and step S500 is not in sequence. Specifically, during the inspection process, step S400 can be executed first, and then step S500. It is also possible to execute step S500 first and then step S400.

[0197] In some embodiments, in order to improve the recognition accuracy of the image recognition device for the second identification straight edge L5, please refer to Figure 16, an identification groove K is provided on the first side wall panel 5112. The identification groove K is formed by the partial inner wall surface of the first side wall panel 5112 recessing towards the outer wall surface of the first side wall panel 5112. Exemplarily, the identification groove K can be formed on the second side plate 5112b. The identification groove K includes a first notch K1, a first groove bottom wall K2, and a first groove side wall K3. The first groove bottom wall K2 is opposite to the first notch K1, and the first groove side wall K3 is located between the first notch K1 and the first groove bottom wall K2. The first groove side wall K3 is parallel to the central axis of the first through hole 5111c (that is, the thickness direction of the first top plate 5111), or 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 in the direction approaching 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 in the direction approaching the first accommodation cavity 5113. The light reflectance of the first groove bottom wall K2 is different from that of the first groove side wall K3.

[0198] In this way, the orthographic projection of the first groove side wall K3 on the first top plate 5111 can be formed as the second identification straight edge L5. And by setting the light reflectance of the first groove bottom wall K2 to be different from that of the first groove side wall K3, the image recognition device can accurately and quickly recognize the second identification straight edge L5, which can improve the assembly efficiency and the accuracy of the detection process. In addition, since the first groove side wall K3 is recessed outward relative to other inner wall surfaces of the first side wall panel 5112, it can prevent the first groove bottom wall K2 from being blocked by structures such as the first buffer member 54, thereby further improving the accuracy of the detection process.

[0199] In some embodiments, a part of the first inner surface 5111b of the first top plate 5111 forms the first groove bottom wall K2, a part of the inner wall surface of the first side wall panel 5112 forms the first groove side wall K3, and the material of the first groove bottom wall K2 is different from that of the first groove side wall K3. For example, the material of the first groove bottom wall K2 is metal, and the material of the first groove side wall K3 is plastic. In this way, the difference in light reflectance between the first groove bottom wall K2 and the first groove side wall K3 is large, which can increase the color difference between the first groove bottom wall K2 and the first groove side wall K3 in the fitted image, so as to clearly and accurately capture the second identification straight edge L5.

[0200] Before assembling the bracket structure 51 to the electronic device 100, in order to improve the dust-proof and waterproof performance of the bracket module 50, please refer to Figures 18 - 19 , Figure 18 which is a schematic structural diagram of the bracket module 50 provided by other embodiments of the present application. Figure 19 For Figure 18Exploded view of the shown bracket module 50. In addition to the bracket structure 51, the light guide member 52, and the adsorption film 56, the bracket module 50 further includes a dust-proof component 57.

[0201] Specifically, the dust-proof component 57 includes a first dust-proof layer 571, a second dust-proof layer 572, and a buffer layer 573. The first dust-proof 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 dust-proof layer 571 covers the first through hole 5111c and surrounds the outer periphery of the light-shielding cylinder 5123.

[0202] The buffer layer 573 is annular, and the buffer layer 573 is fixedly connected to a surface of the first dust-proof layer 571 facing away from the second top plate 5121. Exemplarily, the buffer layer 573 can be fixedly connected to the first dust-proof layer 571 through a second bonding member 574. The buffer layer 573 can be foam, rubber, silica gel, etc. The second dust-proof layer 572 is fixedly connected to an end surface of the buffer layer 573 facing away from the first dust-proof layer 571. A dust-proof cavity is defined between the second dust-proof layer 572, the buffer layer 573, and the first top plate 5111. The light-shielding cylinder 5123 is located in this dust-proof cavity.

[0203] In this way, dust pollution of the light guide member 52 can be avoided, and dust, liquid, etc. can be prevented from entering the interior of the first accommodation cavity 5113 of the first bracket 511, thereby improving the dust-proof and waterproof performance of the bracket module 50; and before assembling the bracket module 50 to the middle frame 21, the entire dust-proof component 57 can be torn off by tearing off the first dust-proof layer 571, which can improve the tearing efficiency of the dust-proof component 57 and save assembly time. Specifically, the first dust-proof layer 571 can be torn off by a manipulator.

[0204] Both the first dust-proof layer 571 and the second dust-proof layer 572 can be release film layers.

[0205] In some embodiments, in order to facilitate tearing off the dust-proof component 57 from the bracket module 50, please refer to Figures 18 - 19 , a second tearing portion 575 is provided on the first dust-proof layer 571, and the second tearing portion 575 is located on the circumferential outer side of the first dust-proof layer 571.

[0206] According to the descriptions 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 automated equipment assembly, effectively reducing the front camera eccentricity in appearance and improving the assembly yield of the electronic device 100.

[0207] In the description of this specification, specific features, structures, materials, or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0208] 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 foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
