Description

Technical Field

[0001] The present application relates to the field of structural technology, and in particular to an electronic device. Background Art

[0002] The display screen of an electronic device may include a display area (also known as "AA") and a black border area (also known as "BX") surrounding the display area. The display area is used to display images, and the black border area is used to shield the internal structure of the electronic device.

[0003] In addition, to facilitate users taking selfies, many electronic devices are equipped with a front camera module. The front camera module can be located below the display area. In some technical solutions, the distance between the camera module and the edge of the display area (i.e., the boundary between the display area and the black border area) is large, which will affect the display effect of the display screen. Utility Model Content

[0004] The present application provides an electronic device for reducing the distance between a camera module and an edge of a display area.

[0005] The present application provides an electronic device comprising a housing, a camera module, a limiting bracket, and a display screen. The housing comprises a panel and a first sidewall connected to the panel, the first sidewall being located on the side of the panel facing a first direction. The camera module is also located on the side of the panel facing the first direction. The camera module is spaced apart from the first sidewall and is located on the side of the first sidewall facing a second direction, the second direction being perpendicular to the first direction. The housing of the camera module comprises a first surface disposed opposite the first sidewall, with a first channel formed between the first surface and the first sidewall. The limiting bracket comprises a pressure plate and a connecting plate, the pressure plate being located on the side of the camera module facing away from the panel, the connecting plate having one end connected to the pressure plate and the other end connected to the first sidewall, the connecting plate extending from one end to the other via the first channel. The display screen is located on the side of the camera module facing the first direction (i.e., the camera module is located between the panel and the display screen). The display screen comprises a connected black border region and a display area (i.e., the black border region and the display area have a boundary, which can be referred to as the "edge of the display area"). The display area is located on the side of the black border region facing the second direction. The display area is provided with a light hole, and the lens of the camera module is aligned with the light hole along a first direction (it can be understood that the camera module is located on the side of the edge of the display area facing the second direction). In the first direction, the first surface gradually shrinks away from the first sidewall.

[0006] According to an embodiment of the present application, the camera module is located between the display screen and the housing panel. To limit the displacement of the camera module between the display screen and the housing panel, the electronic device further includes a position limiting bracket. The position limiting bracket includes a pressure plate and a connecting plate. The connecting plate can connect the position limiting bracket to the first side wall of the housing. The pressure plate is located on the side of the camera module facing away from the housing panel, thereby limiting the camera module along the first direction.

[0007] To install the limiting bracket, a first channel is formed between the first surface of the camera module and the first sidewall. During installation, the connecting plate of the limiting bracket can be passed through the first channel in a direction opposite to the first direction, so that the other end of the connecting plate is connected to the first sidewall and the pressure plate is located on the side of the camera module facing the first direction.

[0008] Because the first surface gradually indents away from the first sidewall along the first direction, the width of the first channel gradually increases along the first direction. In other words, the first surface can avoid the connection plate. This allows only a small gap between the first sidewall and the camera module to meet the installation space requirements for the connection plate.

[0009] Furthermore, because the camera module is located on the side of the display area edge facing the second direction, once the required spacing between the first sidewall and the camera module is reduced, the camera module can be shifted in the direction opposite to the second direction, that is, toward the edge of the display area. In other words, the above-described arrangement of the first surface can reduce the distance between the camera module and the edge of the display area.

[0010] In some embodiments, the housing of the camera module includes a first step, a step edge of the first step is chamfered, and the chamfered surface of the chamfer forms the first surface. The embodiment of the present application can simplify the forming method of the first surface.

[0011] In some embodiments, the first surface is planar.

[0012] In some embodiments, the connecting plate includes a second surface facing the first surface, and the angle between the second surface and the first surface is less than or equal to 20 degrees. This arrangement can increase the degree of clearance of the first surface from the connecting plate, further reducing the distance between the first sidewall and the camera module, thereby further reducing the distance between the camera module and the edge of the display area.

[0013] In some embodiments, the housing of the camera module includes at least one step, and the ascending direction of the at least one step is a first direction; the at least one step includes a first step and a second step, and the first step and the second step are arranged sequentially along the ascending direction; wherein, the step surface of the second step is sealed with the pressure plate, thereby preventing water vapor, dust, etc. from entering the camera module.

[0014] In some embodiments, the first step and the second step are connected.

[0015] In some embodiments, the camera module housing includes two end plates, one located on either side of the connecting plate along a third direction, the third direction being perpendicular to both the first direction and the second direction. Furthermore, the two end plates protrude from the stepped surface of the first step along the first direction. Thus, during assembly of the camera module, the two end plates can be clamped by a fixture to facilitate assembly of the camera module.

[0016] In some embodiments, a projection of the connecting plate along the first direction on the first plane and a projection of the first surface along the first direction on the first plane at least partially overlap, and the first plane is perpendicular to the first direction.

[0017] In some embodiments, the other end of the connecting plate is engaged with the first side wall, thereby simplifying the connection between the connecting plate and the first side wall.

[0018] In some embodiments, the first side wall faces a groove including an opening facing the camera module, and the other end of the buckle extends into the groove and is engaged with the groove wall of the groove.

[0019] In some embodiments, the display screen is located on a side of the first side wall facing the first direction, and the display screen is connected to the first side wall. According to an embodiment of the present application, the first side wall can be used to support the display screen, for example, the display screen can be fixed to the first side wall.

[0020] In some embodiments, the display screen includes a display module and a cover plate sequentially stacked along a first direction, wherein the display screen is connected to the first side wall through the display module.

[0021] According to the embodiment of the present application, the camera module and the first side wall can reuse the width, which is beneficial to reducing the width of the black border area of ​​the display area.

[0022] In some embodiments, the display module and the first side wall are bonded together using adhesive. Compared with hot melt adhesive bonding, adhesive bonding is more conducive to protecting the display module.

[0023] In some embodiments, the pressing plate is used to press the camera module onto the panel, thereby better limiting the position of the camera module. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0034] The embodiment of the present application is used to provide an electronic device, which has a smaller black border area and can also reduce the distance between the front camera module and the black border area.

[0035] In this application, the electronic device may be a mobile phone, a tablet computer, a laptop computer, an ultra-mobile personal computer (UMPC), a handheld computer, a touch-screen TV, a large-screen device, a speaker, a walkie-talkie, a netbook, a POS machine, a personal digital assistant (PDA), a wearable device, a virtual reality device, an intelligent vehicle, an intelligent robot, an industrial equipment, etc., and this application does not limit it.

[0036] Hereinafter, a foldable mobile phone is used as an example of an electronic device to introduce the technical solution of the present application.

[0037] The following describes specific embodiments of the present application with reference to the accompanying drawings. Figure 1A and Figure 1B FIG1 shows an exemplary structural diagram of the mobile phone 100 provided in an embodiment of the present application (folded state). Figure 1A is a front view of the mobile phone 100, Figure 1B It is a side view of the mobile phone 100.

[0038] In the various figures herein, the X-axis direction may be the length direction of the mobile phone 100, the Y-axis direction may be the width direction of the mobile phone 100, and the Z-axis direction may be the thickness direction of the mobile phone 100. The X-axis direction, the Y-axis direction, and the Z-axis direction may be perpendicular to each other. During the process of switching the mobile phone 100 from the folded state to the flat state, the size of the mobile phone 100 in the X-axis direction may gradually increase, the size in the Z-axis direction may first increase and then decrease, and the size in the Y-axis direction may remain unchanged. In addition, the size of the mobile phone 100 in the length direction may be greater than the size of the mobile phone 100 in the width direction, or may be less than or equal to the size of the mobile phone 100 in the width direction.

[0039] In addition, it should be noted that the directional terms such as "up", "down", "left", "right", "front", "back", "top", and "bottom" in this document are exemplary orientations of electronic devices and their components, and do not indicate or imply that the referred components must have a specific orientation. They can change accordingly according to actual usage and cannot be understood as limitations on this application.

[0040] It is understood that the term "perpendicular" in this application does not necessarily mean absolute perpendicularity. Approximate perpendicularity due to processing errors and assembly errors (for example, an angle of 89.9° between two structural features) is also within the scope of "perpendicular" in this application. The term "parallel" in this application does not necessarily mean absolute parallelism. Approximate parallelism due to processing errors and assembly errors (for example, an angle of 0.1° between two structural features) is also within the scope of "parallel" in this application. The definitions of "parallel" and "perpendicular" will not be repeated below.

[0041] refer to Figure 1A and Figure 1B , the mobile phone 100 includes a first part 101 and a second part 102 that can be folded or unfolded with each other. The first part 101 may include an outer screen 10 (as an example of a display screen), a middle frame 20 (as an example of a shell) and an inner screen 30. Along the Z-axis direction, the outer screen 10 and the inner screen 30 are respectively located on opposite sides of the middle frame 20. The outer screen 10, the middle frame 20 and the inner screen 30 can together form the outer shell of the first part 101. The second part 102 may include an inner screen 40, a middle frame 50 and a back cover 60. Along the Z-axis direction, the inner screen 40 and the back cover 60 are respectively located on opposite sides of the middle frame 40. The inner screen 10, the middle frame 50 and the back cover 60 can together form the outer shell of the second part 102. In addition, the inner screen 30 and the inner screen 40 can be two parts of the same flexible screen.

[0042] refer to Figure 1A, the outer screen 10 may include a display area AA and a black border area BX. The display area AA may be used to display a screen (for example, the application interface of the mobile phone 100), and the black border area BX may be an opaque structure or a structure with poor light transmittance to block the internal structure of the mobile phone 100. There may be multiple black border areas BX. For example, the black border area includes a black border area BX01 and a black border area BX02 that are relatively arranged along the Y-axis direction, and a black border area BX03 and a black border area BX04 that are relatively arranged along the X-axis direction. The black border areas BX01, BX02, BX03, and BX04 may together form a frame surrounding the display area AA. In other embodiments, the black border area BX may also be arranged in other ways, for example, the black border area BX02 is not included.

[0043] The mobile phone 100 may also include a camera module 70, which allows users to take selfies. For example, when the user faces the external screen 10, the camera module 70 can capture the user's image, and the external screen 10 can simultaneously display the image captured by the camera module 70. This allows the user to preview the image captured by the camera module 70 in real time, making it easier to adjust the photo posture. The camera module 70 may also be referred to as the "front camera module 70."

[0044] The camera module 70 can be disposed near the black border area BX01. Since the camera module 70 is usually located at the top of the mobile phone 100 when the user uses the mobile phone 100 to take a selfie, the black border area BX01 is referred to as the top black border area BX01 and the black border area BX02 is referred to as the bottom black border area BX02.

[0045] For ease of understanding, in this article, the positive direction of the Y axis can be the direction from the bottom black border area BX02 to the top black border area BX01, and the positive direction of the Z axis can be the direction from the inner screen 30 of the first part 101 to the outer screen 10.

[0046] It is understandable that Figure 1A and Figure 1B This is only an exemplary structure of the mobile phone 100, and those skilled in the art may make other modifications. For example, in other embodiments, the mobile phone 100 may be a straight-screen mobile phone, which may include a main display screen (as an example of a display screen), a middle frame (as an example of a housing), and a battery cover. The configuration of the main display screen, the middle frame, and the battery cover may refer to Figure 1B The arrangement of the inner screen 40, the middle frame 50, and the back cover 60 in the second portion 102 is shown. In other embodiments, the candy bar phone may not include a middle frame, and the main display screen (as an example of a display screen) of the phone may be directly covered on the battery cover (as an example of a housing), so that the main display screen and the battery cover can together form the housing of the candy bar phone.

[0047] Figure 2The exemplary structure of the first part 101 (specifically, Figure 1A AA cross-sectional view of the first part 101 in FIG. Figure 2 Combined with Figure 1A The first part 101 of the mobile phone 100 may include a middle frame 20 , an outer screen 10 , a display module 11 , a limiting bracket 80 and an inner screen 30 .

[0048] The middle frame 20 may include a panel 21 and multiple side walls connected to the panel 21, for example, a side wall 22 (serving as a second side wall) and a side wall 23 (serving as a first side wall). Side walls 22 and 23 may be located on the side of the panel 21 facing the positive direction of the Z axis (serving as the first direction). Side walls 22 and 23 may be spaced apart along the Y axis to form a sound channel 103 for the mobile phone 100. Specifically, side wall 23 may be located on the side of the side wall 22 facing the negative direction of the Y axis (serving as the second direction). The sound channel 103 may communicate with the sound outlet 104 at the top of the mobile phone 100, and may also communicate with the sound outlet 105 on the front side of the mobile phone 100. The sound outlet 104 may be formed by a notch on the top edge of the outer screen 10, and the sound outlet 105 may be formed by a through hole on the top wall of the mobile phone 100. For example, the width of the side wall 22 is denoted as A11, and the width of the sound outlet channel 103 is denoted as A12.

[0049] The external screen 10 is located on the side of the sidewall 23 and the camera module 70 facing the positive Z-axis direction. The external screen 10 can be installed on the sidewall 23. The external screen 10 can include a display module 11 and a cover plate 12 (e.g., a glass cover plate 12) stacked in sequence along the positive Z-axis. The display module 11 is used to realize the display function of the external screen 10, and the cover plate 12 is used to protect the display module 11.

[0050] In this embodiment, the cover plate 12 includes a portion 121 protruding from the display module 11 along the positive direction of the Y-axis, and the portion 121 is bonded to the side wall 23 by a sealant 91 (for example, hot melt adhesive) so that the outer screen 10 is fixedly connected to the side wall 23 of the middle frame 20. To ensure the connection strength, the sealant 91 needs to have a certain width A13. The width A13 can be equal to or approximately equal to the width of the side wall 23. For ease of understanding, in this embodiment, the width of the side wall 23 is regarded as equal to the width A13 of the sealant 91. In addition, in order to avoid interference between the camera module 70 and the side wall 23 during installation, there is also an avoidance distance A14 between the display module 11 and the side wall 23 of the middle frame 20.

[0051] Furthermore, the display module 11 may include a display area 111 and a non-display area 112. The display area 111 includes a plurality of pixel units for displaying images of the electronic device. The non-display area 112 is used to set the wiring, control components, etc. of the display module 11 and is usually not used for displaying images. For easy observation, Figure 2 The display area 111 and the non-display area 112 are represented by different types of hatching. In addition, protective glue 113 can be provided at the end of the non-display area 112 to protect the internal components of the display module 11. The width of the non-display area 112 is denoted as A15.

[0052] The outer screen 10, the side wall 23 of the middle frame 20 and the panel 21 of the middle frame 20 can form a accommodating cavity 101a, which can accommodate electronic components of the mobile phone 100, such as the camera module 70, a speaker (not shown), a battery (not shown), etc.

[0053] The camera module 70 is located between the outer screen 10 and the panel 21 of the middle frame 20. Specifically, the camera module 70 can be located on the side of the panel 31 facing the positive direction of the Z axis and below the outer screen 10. In addition, the middle frame 20 can include positioning steps 24, which can provide positioning for the camera module 70 along the X-axis and Y-axis directions.

[0054] The camera module 70 may include a lens 71 and an image processing component 72. The lens 71 may be located on the side of the image processing component 72 facing the positive direction of the Z axis. The lens 71 may include a lens barrel 711 and one or more lenses 712 ( Figure 2 (The figure shows two lenses 712 in the figure). The diameter of the lens 71 is denoted as R2. The image processing component 72 may include an image sensor 721 and an image processing chip. The lenses 712 focus external light onto the image sensor 721, which converts the light focused by the lenses 712 into electrical signals. The image processing chip then converts these electrical signals into digital image signals. The image processing chip can also perform color correction, contrast enhancement, noise reduction, and other processing on the image to improve image quality.

[0055] A light hole 13 can be provided on the external screen 10, and the lens of the camera module 70 and the light hole 13 can be aligned along the Z-axis direction, so that external light can be incident on the lens of the camera module 70 through the light hole 13. For example, the top of the lens 71 can be located in the light hole 13 to facilitate receiving external light. The display area 111 can also include a wiring area 1111, which can be an annular area surrounding the light hole 13. Wiring and the like can be set inside the wiring area 1111, which is usually not used to display images. In this embodiment, the radius of the wiring area 1111 is denoted as R1.

[0056] The mobile phone 100 may further include a limiting bracket 80. The limiting bracket 80 is used to provide a limit for the camera module 70 along the Z-axis direction, that is, the limiting bracket 80 can limit the displacement of the camera module 70 along the Z-direction within a certain range, for example, ±0.2 mm. Exemplarily, the limiting bracket 80 can press the camera module 70 onto the panel 21 of the middle frame 20 to better limit the camera module 70. The limiting bracket 80 includes a pressing plate 81 and a connecting plate 82, the pressing plate 81 being located above the camera module 70, one end 821 of the connecting plate 82 being connected to the pressing plate 81, and the other end 822 being connected to the side wall 23 of the middle frame 20 to connect the limiting bracket 80 to the middle frame 20. That is, the connecting plate 82 can serve as a connecting structure between the limiting bracket 80 and the middle frame 20. It is understood that the limiting bracket 80 may also include multiple other connection structures, such as bolt connection structures (not shown) arranged at other locations on the limiting bracket 80. When the limiting bracket 80 is fixed to the middle frame 20 via multiple connection structures, the pressure plate 81 can provide position limitation for the camera module 70 along the Z-axis direction. That is, the pressure plate 81 can press the camera module 70 onto the panel 21 of the middle frame 20.

[0057] In this embodiment, the other end 822 of the connecting plate 82 is engaged with the side wall 23, and therefore, the connecting plate 82 can also be referred to as a buckle 82. For example, a groove 231 is formed on the side wall 23, the opening of which faces the camera module 70. The other end of the buckle 82 extends into the groove 231 and engages with the groove wall 231a of the groove 231. In other embodiments, the connecting plate 82 can be connected to the side wall 23 by other means, such as plugging, bonding, etc.

[0058] It can be understood that in order to set the buckle 82, a certain distance is required between the side wall 23 and the camera module 70 to provide an installation channel for the buckle 82. For example, the camera module 70 needs to be located on one side of the buckle 82. In other words, the projection of the lens 71 along the X direction does not overlap with the projection of the buckle 82 along the X direction. During the installation of the electronic device, the camera module 70 can be first installed on the panel 21 of the middle frame 20, and then the pressure plate 81 can be covered on top of the camera module 70, and the buckle 82 can be passed through the installation channel and snapped onto the side wall 23. In this embodiment, the distance between the side wall 23 and the camera module 70 is recorded as A17.

[0059] In addition, for the aesthetics of the electronic device, the cover 12 includes a light shielding portion 122. The light shielding portion 122 can be a non-transparent structure or a structure with poor light transmittance, used to block parts of the electronic device that the user does not want to observe, such as the sound outlet channel 103, the side wall 23, and the non-display area 112 of the display module 11. The light shielding portion 122 and the portion of the display module 11 covered by the light shielding portion 122 can form the black border area BX01 of the external screen 10. Figure 2The other areas of the middle and outer screens are display areas AA. It can be understood that the display area AA is located on the side of the black border area BX01 facing the negative direction of the Y axis. Figure 2 As shown, the width D1 of the black border area BX01 may be: width D1 = A12 + A13 + A14 + A15. Figure 2 In the example shown, the width D1 of the black border area BX01 is approximately 2.0 mm to 2.5 mm, which is relatively large and affects the screen-to-body ratio of the mobile phone 100 .

[0060] After the camera module 70 is arranged below the external screen 10, it will have a certain impact on the display effect of the external screen 10. For example, since the light hole 13 and the wiring area 1111 cannot display images, in some embodiments, for the integrity of the image display, the main image is displayed only in the portion to the right of the wiring area 1111, while the portion where the light hole 13 and the wiring area 1111 are located does not display an image or only displays some simple information, such as the battery status and signal status of the mobile phone 100, which reduces the utilization rate of the display area of ​​the external screen 10.

[0061] Therefore, in order to improve the display effect of the external screen 10, it is desirable to minimize the distance S1 between the camera module 70 and the edge of the display area AA, thereby minimizing the distance between the edge 1111a of the wiring area 1111 and the edge of the display area AA. Figure 2 In this embodiment, the distance S1 = A17 + R2 - A14 - A15. For example, S1 can be 1.5 mm to 2.8 mm. In this embodiment, the edge 1111a of the wiring area 1111 is relatively close to the edge of the display area AA, which is conducive to better display of the external screen 10.

[0062] Figure 3 FIG2 shows an exemplary structure of the first part 101 of the mobile phone 100 in the second embodiment of the present application. This embodiment can be based on the first embodiment (for example, Figure 2 Compared with the first embodiment, the width of the black border area BX01 can be reduced in this embodiment.

[0063] refer to Figure 3 In this embodiment, the first part 101 of the mobile phone 100 includes the middle frame 20, the outer screen 10, the display module 11, and the limiting bracket 80. The outer screen 10 is supported on the side wall 23 of the middle frame 20, the display module 11 is arranged between the outer screen 10 and the panel 21 of the middle frame 20, and the limiting bracket 80 is used to press the camera module 70 onto the panel 21 of the middle frame 20.

[0064] The main difference between this embodiment and the first embodiment is that the outer screen 10 is not bonded to the side wall 23 of the middle frame 20 through the cover plate 12, but is bonded to the side wall 23 of the middle frame 20 through the display module 11. Specifically, the display module 11 and the side wall 23 are bonded by adhesive 92. Compared with hot melt adhesive bonding, adhesive bonding is more conducive to protecting the display module 11. For the reliability of the connection, the adhesive 92 needs to have a width A13'. Among them, the width A13' of the adhesive 92 is greater than Figure 2 In the embodiment shown, the width A13 of the sealant 91 , the difference between the width A13 ′ and the width A13 can be 0.5 mm to 1 mm. In addition, the protective sealant 113 at the end of the display module 11 can protect the internal components of the display module 11 .

[0065] In addition, to prevent interference between the camera module 70 and the sidewall 23 during installation, a clearance space is required between the display module 11 and the sidewall 22 of the middle frame 20. The width of the clearance space is A14. It is understood that the width of the sound output channel 103 and the clearance space can be reused. That is, after the sound output channel 103 is installed, the clearance space can be formed by the sound output channel 103, eliminating the need for additional clearance space.

[0066] Therefore, in this embodiment, the width D2 of the black border area BX01 of the outer screen 10 can be: width D2 = W12 + W15. Compared to the first embodiment, the width of the black border area BX01 is reduced by A13 + A14. That is, this embodiment can reduce the width of the black border area BX01 of the outer screen 10 and increase the screen-to-body ratio of the outer screen 10. In this embodiment, the width of the black border area BX01 of the outer screen 10 can be reduced to 1.2mm to 1.6mm, for example, 1.4mm.

[0067] In this embodiment, the distance S2 between the camera module 70 and the edge of the display area AA is equal to A13' + A17 - A15 + R2. The meanings of A17, A15, and R2 can be referred to the description of the first embodiment. Therefore, compared with the first embodiment, the distance between the camera module 70 and the edge of the display area AA is increased by A13' + A14. The distance between the edge 1111a of the routing area 1111 and the edge of the display area AA is increased by A13' + A14). In this embodiment, the distance S2 can be 3mm to 3.5mm, which is approximately 0.7mm to 1.5mm higher than the distance S1 in the first embodiment.

[0068] In addition, other details not described in this embodiment, such as other structural details of the middle frame 20, the outer screen 10, the camera module 70, and the limiting bracket 80, can be referred to the description of the first embodiment and will not be repeated here.

[0069] That is to say, in the second embodiment, by setting the connection method between the external screen 10 and the side wall 23 to bond the display module 11 to the side wall 23, the width of the black border area BX01 can be reduced, but the distance between the camera module 70 and the edge of the display area AA is increased.

[0070] Therefore, the present application also provides a third embodiment, which reduces the distance between the display module 11 and the side wall 23 to achieve a smaller width of the black border area BX01 while reducing the distance between the camera module 70 and the edge of the display area AA.

[0071] Figure 4 FIG3 shows an exemplary structure of the first part 101 of the mobile phone 100 in the third embodiment of the present application. This embodiment can be based on the second embodiment. Figure 4 In this embodiment, the first part 101 of the mobile phone 100 includes the middle frame 20, the outer screen 10, the display module 11, and the limiting bracket 80. The outer screen 10 is supported on the side wall 23 of the middle frame 20, the display module 11 is arranged between the outer screen 10 and the panel 21 of the middle frame 20, and the limiting bracket 80 is used to press the camera module 70 onto the panel 21 of the middle frame 20.

[0072] The main difference between this embodiment and the second embodiment is that the housing of the camera module 70 has a relief structure for avoiding the buckle 82. By providing this relief structure, the distance between the middle frame 20B and the camera module 70 can be reduced, thereby reducing the distance between the edge 1111a of the wiring area 1111 and the edge of the display area AA. A detailed description is provided below.

[0073] Figure 5 The figure shows the installation relationship between the middle frame 20, the camera module 70 and the limiting bracket 80. Figure 6 FIG. 7 shows a schematic diagram of the appearance of the camera module 70. Figures 4 to 6 The housing of the camera module 70 (specifically, the barrel 711 of the lens 71) includes a first surface 73, which is disposed opposite to the side wall 23. A channel 106 (as a first channel) can be formed between the first surface 73 and the side wall 23.

[0074] As described above, one end 821 of the buckle 82 is connected to the pressure plate 81, and the other end 822 is engaged with the side wall 23. The buckle 82 can extend from its one end 821 to the other end 822 via the channel 106. That is, during the installation process of the buckle 82, the channel 106 can serve as an installation channel for the buckle 82.

[0075] In this embodiment, along the positive direction of the Z axis, the first surface 73 gradually retracts away from the side wall 23 (ie, the negative direction of the Y axis) to avoid the buckle 85. Specifically, the space above the first surface 73 ( Figure 4The space R) surrounded by the dotted line can form an avoidance space for the buckle 82. In other words, the width of the channel 106 gradually increases along the positive direction of the Z axis. In this way, only a small spacing needs to be set between the side wall 23 and the camera assembly to meet the installation space requirements of the buckle 82. For example, by setting the avoidance space R, at least part of the structure of the buckle 82 can be located above the camera module 70. That is, the projection of the buckle 82 along the Z axis on the plane P (as the first plane) and the projection of the first surface 73 along the Z axis on the plane P at least partially overlap. Wherein, the plane P is perpendicular to the Z axis. In this embodiment, by setting the first surface 73, the distance between the side wall 23 and the camera assembly can be reduced from A17 of the second embodiment to A17'. Exemplarily, the difference between A17 and A17' can be 0.3mm to 0.4mm.

[0076] It is understood that in this embodiment, the width D3 of the black border area BX01 of the outer screen 10 can be: width D3 = A12 + A15. That is, the width D3 of the black border area BX01 of this embodiment can be the same as the width D2 of the second embodiment, with a smaller black border area BX01 width.

[0077] In addition, the distance S3 between the camera module 70 and the edge of the display area AA is equal to A13' + A17' - A15 + R2. That is, compared to the second embodiment, in this embodiment, the distance between the camera module 70 and the edge of the display area AA is reduced by (A17 - A17'). Accordingly, the distance between the edge 1111a of the routing area 1111 and the edge of the display area AA is also reduced by (A17 - A17'), thereby improving the display effect of the external screen 10.

[0078] In summary, this embodiment can reduce the distance between the front camera module 70 and the black border area BX01 while having a smaller black border area BX01.

[0079] The following describes an exemplary method for forming the first surface 73. Figures 4 to 6 The lens barrel 711 includes a step structure 74, which includes at least one step. The ascending direction of the step structure 74 is the positive direction of the Z axis. Figure 4In the illustrated example, step structure 74 includes two steps, namely step 741 (serving as a first step) and step 742 (serving as a second step), and steps 741 and 742 are connected. Steps 741 and 742 are arranged sequentially along an ascending direction. Furthermore, since the ascending direction of step structure 74 is the positive direction of the Z axis, it can be understood that surface 741a is the step surface of step 741, surface 741b is the step side surface of step 741, and the intersection of surfaces 741a and 741b is the step edge 741c of step 741. Surface 742a is the step surface of step 742, and surface 742b is the step side surface of step 742.

[0080] A chamfer 78 is provided on the edge 741c of the step 741. The chamfered surface of the chamfer 78 can form the first surface 73. This embodiment simplifies the forming method of the first surface 73. For ease of understanding, the first surface 73 may be referred to as the chamfered surface 73 below. The chamfered surface 73 can be formed by cutting or molding, and this application is not limited thereto. Figure 4 In the illustrated example, the chamfered surface 73 is a flat surface. In other examples, the chamfered surface 73 may also be a curved surface, such as a circular arc surface. In some embodiments, the angle θ between the chamfered surface 73 and the stepped surface 741a can be set according to the structural dimensions of the buckle 82. For example, the angle θ can be 20° to 70°, such as 20°, 45°, 50°, etc., and is not limited in this application.

[0081] Additionally, in some implementations, reference Figure 6 , a chamfered surface 73 is provided on a portion of the extended section of the step edge 741c. Figure 7 The chamfered surface 73 can be provided on the entire extension section of the step edge 741 c of the step 741 as long as the buckle 82 can be avoided.

[0082] Additionally, in some implementations, reference Figure 6 , the starting point of the chamfered surface 73 (ie, the side 731 of the chamfered surface 73) may be spaced a distance from the step side 742b. Figure 8 , the side edge 731 of the chamfered surface 73 may coincide with the step side surface 742b.

[0083] In other embodiments, the first surface 73 may also be formed by other means. For example, a connecting slope for connecting 742b and the surface 741b may be provided on the outer shell of the camera module 70 , and the connecting slope may form the first surface 73 .

[0084] Further, refer to Figure 4The buckle 82 also includes a second surface 823 facing the first surface 73. The angle α between the first surface 73 and the second surface 823 can be less than or equal to 20°. For example, the angle α can be 0°, 5°, etc. In other words, the first surface 73 can serve as a contoured surface for the second surface 823. This arrangement can improve the clearance of the first surface 73 from the buckle 82, further reducing the distance A17' between the sidewall 23 and the camera module 70.

[0085] In addition, reference Figure 6 The housing of the camera module 70 may further include two end plates, namely, end plate 75 and end plate 76. Along the X-direction, end plates 75 and 76 are located on either side of the buckle 82. Furthermore, end plates 75 and 76 protrude from the step surface 741a of step 741 along the positive Z-axis. Thus, during the assembly process of the lens 71, end plates 75 and 76 can be clamped by a fixture to facilitate the assembly of the lens 71.

[0086] Continue to refer Figure 4 The pressure plate 81 and the step surface 742a of the step 742 can be sealed to prevent external moisture, dust, etc. from entering the camera module 70 through the gap between the pressure plate 81 and the step surface 742a. ​​For example, the pressure plate 81 and the step surface 742a of the step 742 can be sealed by a sealing foam 93.

[0087] In addition, the lens barrel 711 and the image processing assembly 72 can also be sealed to prevent external moisture, dust, etc. from entering the camera module 70 through the gap between the lens barrel 711 and the image processing assembly 72. Exemplarily, the lens barrel 711 and the image processing assembly 72 can be sealed by a sealing foam 94.

[0088] For other details not described in this embodiment, such as other structural details of the middle frame 20, the outer screen 10, the camera module 70, and the limiting bracket 80, reference can be made to the description of the second embodiment and will not be repeated here.

[0089] In the above description of this embodiment, unless otherwise specified, " / " represents or. For example, A / B can identify either A or B. "And / or" in this document simply describes an association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent the existence of A alone, B alone, or both A and B. Furthermore, in this embodiment, the values ​​of each data range include the end values. For example, A=10-50 means that A can be 10 or 50.
