Description

Technical Field

[0001] The present disclosure relates to the technical field of mobile terminals, and in particular to an electronic device. Background Art

[0002] As consumers' requirements for the screen-to-body ratio of electronic devices increase, R&D personnel have proposed screen structure solutions such as narrow bezels, notch screens, water drop screens, and hole-punch screens to increase the screen-to-body ratio of electronic devices in order to obtain a wider field of view experience.

[0003] In the structure of water drop screen and hole screen, the aperture of the window hole on the display screen of the electronic device is determined by the field of view of the camera module and its distance from the display screen. The closer the camera module is to the display screen, the smaller the field of view is, the smaller the window hole is, and the smaller the shading area of ​​the shading film can be, the larger the screen-to-body ratio is. However, the closer the camera module is to the display screen, the higher the risk of the camera module hitting the display screen due to external forces.

[0004] Therefore, it is difficult to simultaneously take into account the high screen-to-body ratio of electronic devices and the protection of the camera module. Summary of the invention

[0005] The main purpose of the embodiments of the present disclosure is to provide an electronic device, aiming to at least achieve that the electronic device can simultaneously have a high screen-to-body ratio and a protected camera module.

[0006] The disclosed embodiment provides an electronic device, which includes: a display screen, a middle frame and a camera module. The middle frame includes a middle plate, an annular enclosure and a support plate. The middle plate is located at the rear side of the display screen, and an opening is provided on the middle plate. The annular enclosure is fixedly connected to the middle plate and protrudes toward the rear side of the middle plate. The inner circumference of the annular enclosure forms an inner hole. The central axis of the inner hole is coaxially arranged with the central axis of the opening, and the aperture of the inner hole is less than or equal to the aperture of the opening. The support plate is located at the rear side of the middle plate and is fixedly connected to one end of the annular enclosure away from the display screen. The middle plate, the inner circumference of the annular enclosure and the support plate together form an installation space. The camera module is accommodated in the installation space, and the fixed end of the camera module is fixedly connected to the support plate.

[0007] The electronic device of the disclosed embodiment is designed such that the camera module is installed in the installation space surrounded by the middle plate, the inner circumference of the annular enclosure and the support plate, and the fixed end of the camera module is no longer against the shell, but is fixed to the support plate of the middle frame. In this way, the support plate provides support for the camera module to reduce the possibility of external force being transmitted to the camera module, thereby reducing the risk of the camera module being pressed forward by external force and the display screen, thereby protecting the camera module. Moreover, the camera module and the display screen are not separated by the middle plate, so the camera module can be closer to the display screen, and the smaller the field of view, the higher the screen-to-body ratio can be.

[0008] In summary, the electronic device of this embodiment has both a high screen-to-body ratio and protection for the camera module. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] It should be understood that the specific embodiments described herein are only used to explain the present disclosure, and are not used to limit the present disclosure.

[0024] In the subsequent description, suffixes such as "device", "structure", "module", "component" or "piece" used to represent elements are used only to facilitate the description of the embodiments of the present disclosure, and have no specific meanings. Therefore, "device", "structure", "module", "component" or "piece" can be used in a mixed manner.

[0025] In previous examples, the camera module of the electronic device is set on the middle plate, and the shell presses down the camera module, so that the light in the external environment can pass through the opening on the middle plate into the camera module. In this way, the middle plate can provide support for the camera module. In actual applications, when the electronic device falls to the ground with the back of the electronic device facing down, or when the user presses the area corresponding to the camera module on the shell, there is an external force acting on the shell, and the external force will be transmitted to the camera module. The camera module can transmit the external force to the middle plate to prevent the camera module from being affected by the external force and being overly squeezed toward the front side of the electronic device, so as to prevent the camera module from hitting the display screen and causing damage to the camera module or the display screen.

[0026] By adopting this method, the camera module of the electronic device is protected to a certain extent, but the distance between the camera module and the display screen is far, and the field of view of the camera module is large, so the window hole is large, which affects the screen-to-body ratio of the electronic device.

[0027] With the development of electronic equipment technology, the demand for high screen-to-body ratio is becoming more and more urgent. Therefore, how to design electronic equipment with both high screen-to-body ratio and camera module protection has become an urgent problem to be solved.

[0028] To this end, the following embodiments of the present disclosure provide an electronic device, including but not limited to mobile phones, tablet computers, laptop computers, ultra-mobile personal computers (UMPCs), handheld computers, walkie-talkies, netbooks, POS machines, personal digital assistants (PDAs), wearable devices, virtual reality devices, wireless USB flash drives, Bluetooth speakers, Bluetooth headsets, or vehicle-mounted devices, and other electronic devices with cameras. Figure 1 Schematic diagram of the structure of an electronic device provided in an embodiment of the present disclosure. In the embodiment of the present disclosure, the electronic device 100 is Figure 1 The mobile phone shown is used as an example for explanation. It should be noted that in each of the drawings of the embodiments of the present disclosure, the directions of the X-axis, Y-axis, and Z-axis represent the width direction, length direction, and thickness direction of the electronic device 100, respectively.

[0029] Figure 2 for Figure 1 The exploded schematic diagram of the electronic device 100 is shown. Figure 3 for Figure 1 The cross-sectional diagram at AA is shown. Figure 4 for Figure 1 See the schematic cross section at BB. Figures 1 to 4The electronic device 100 includes a middle frame 10, a display screen 20 and a housing 40. The middle frame 10 includes a middle plate 11. The display screen 20 is located on the front side of the middle plate 11 and is opposite to the middle plate 11. The housing 40 is located on the rear side of the middle plate 11 and is connected to the middle frame 10. The front side of the middle plate 11 refers to the side of the middle plate 11 facing the user, and correspondingly, the rear side of the middle plate 11 refers to the side of the middle plate 11 facing away from the user. It can be understood that the middle plate 11 has a first surface and a second surface disposed opposite to each other along its thickness direction Z, the first surface is close to the display screen 20, and the second surface is far away from the display screen 20.

[0030] The middle frame 10 further includes an annular enclosure 12 and a support plate 13. The middle plate 11 is provided with an opening 111. The annular enclosure 12 is fixedly connected to the middle plate 11 and protrudes toward the rear side of the middle plate 11. The inner circumference of the annular enclosure 12 forms an inner hole, and the central axis of the inner hole is coaxially arranged with the central axis of the opening 111. The support plate 13 is located at the rear side of the middle plate 11 and is fixedly connected to one end of the annular enclosure 12 away from the display screen 20. The middle plate 11, the inner circumference of the annular enclosure 12 and the support plate 13 together form an installation space.

[0031] Here, the fixed connection between the annular enclosure 12 and the middle plate 11 should be understood in a broad sense. For example, in one case, it can be understood that the annular enclosure 12 is connected to the second surface of the middle plate 11. In this embodiment, the aperture of the inner hole can be equal to the aperture of the opening 111, and the inner circumference of the annular enclosure 12 is coplanar with the hole wall of the opening 111. For another example, in another case, the annular enclosure 12 extends into the opening 111, and the outer circumference of the annular enclosure 12 is connected to the hole wall of the opening 111. At this time, the aperture of the inner hole is smaller than the aperture of the opening 111. In general, the aperture of the inner hole is smaller than or equal to the aperture of the opening 111, so that the orthographic projection of the middle plate 11 on the display surface of the display screen 20 and the orthographic projection of the inner hole on the display surface of the display screen 20 do not have an overlapping area, and there is no part protruding from the inner hole on the middle plate 11. Here, the display surface of the display screen 20 refers to the side of the display screen 20 facing the user when the user uses the electronic device 100.

[0032] The display screen 20 is connected to the middle frame 10, and the display screen 20 is used to display images and videos. The display screen 20 can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MIL-E) display screen, a micro organic light-emitting diode (MIL-E) display screen, a micro organic light-emitting diode (MIL-E) display screen, a quantum dot light-emitting diode (QLED) display screen, or a liquid crystal display (LCD).

[0033] The display screen 20 is provided with a window hole 21, and the central axis of the window hole 21 is coaxially arranged with the central axis of the opening 111. It should be noted that the display screen 20 implemented in the present disclosure can be Figure 1 The hole-punch screen shown can also be a water drop screen. Figure 1 As shown, the window hole 21 can be set at the upper part of the display screen 20, for example, at the upper left corner, upper right corner or center of the display screen 20. The size of the window hole 21 is not specifically limited in this embodiment, and the size of the window hole 21 is as small as possible while meeting the field of view range of the camera module 50 (see below).

[0034] The electronic device 100 further includes a transparent cover plate 30, which covers the display surface of the display screen 20. The transparent cover plate 30 may be, for example, a glass cover plate or a sapphire cover plate. The side of the transparent cover plate 30 facing away from the display screen 20 is exposed to the external environment to receive the touch of the user. The transparent cover plate 30 can protect the display screen 20, and the display screen 20 can display through the transparent cover plate 30. In some embodiments, a light shielding film 31 may be formed on the inner surface of the transparent cover plate 30 by a process such as silk screen printing. The light shielding film 31 may be, for example, made of ink, Mylar or other materials. The light shielding film 31 is annular, and a light-transmitting hole 32 is formed in the middle of the light shielding film 31. The central axis of the light-transmitting hole 32 is coaxially arranged with the central axis of the window hole 21. The aperture d2 of the light-transmitting hole 32 is smaller than the aperture d1 of the window hole 21, and the aperture d1 of the window hole 21 is smaller than the aperture of the opening 111.

[0035] Please continue reading Figures 1 to 4In order to realize the shooting function, the electronic device 100 further includes a camera module 50, which is accommodated in the installation space, and the fixed end of the camera module 50 is fixedly connected to the support plate 13, and the lens end of the camera module 50 faces the display screen 20. In this way, the light in the external environment can pass through the transparent cover plate 30, and enter the camera module 50 located in the installation space through the light-transmitting hole 32, the window hole 21 and the opening 111 in sequence, so that the camera module 50 can collect light to form an image, and the light emitted by the optical device (such as a flash) of the camera module 50 can pass through the opening 111, the window hole 21, the light-transmitting hole 32 and the transparent cover plate 30 in sequence to the external environment. Here, because the aperture d2 of the light-transmitting hole 32 is smaller than the aperture d1 of the window hole 21, the light-shielding film 31 can block the hole wall of the window hole 21 and the hole wall of the opening 111 to prevent light leakage at the hole wall of the window hole 21.

[0036] The fixed end of the camera module 50 may be connected to the support plate 13 by bonding with adhesive, or the fixed end of the camera module 50 may be connected to the support plate 13 by snapping.

[0037] An exemplary assembly process of the electronic device 100 in this embodiment is: providing a middle frame 10; providing a camera module 50, moving the camera module 50 to the front side of the middle plate 11 to align with the inner hole, and making the lens end of the camera module 50 face the front side of the middle plate 11; moving the camera module 50 into the installation space, and making the fixed end of the camera module 50 fixedly connected to the support plate 13; providing a display screen 20, moving the display screen 20 to the front side of the middle plate 11, and connecting the display screen 20 to the middle frame 10; providing a transparent cover plate 30, moving the transparent cover plate 30 to the front side of the display screen 20, and covering the display surface of the display screen 20 with the transparent cover plate 30.

[0038] In the electronic device 100 of this embodiment, since the aperture of the inner hole is less than or equal to the aperture of the opening 111, there is no portion protruding from the inner hole on the middle plate 11, and the camera module 50 installed in the installation space is not separated from the display screen 20 by the middle plate 11, and the fixed end of the camera module 50 is no longer against the shell 40, but is fixed on the support plate 13 of the middle frame 10, and the support plate 13 located on the rear side of the middle plate 11 provides support for the camera module 50. Therefore, on the one hand, when the electronic device 100 falls and the back of the electronic device 100 hits the ground, or when the user presses the area corresponding to the camera module 50 on the back of the electronic device 100, the shell 40 is subjected to an external force F, and the external force F is transmitted to the middle frame 10 connected to the shell 40, so as to prevent the external force F from being directly transmitted to the camera module 50, thereby reducing the risk of the camera module 50 being affected by the external force F and squeezing the display screen 20 forward. On the other hand, since there is no middle plate 11 between the camera module 50 and the display screen 20 in this embodiment, the camera module 50 can be closer to the display screen 20 without changing the height of the camera module 50, and the smaller the field of view, the higher the screen-to-body ratio can be. In summary, the electronic device 100 of this embodiment has both a high screen-to-body ratio and a protective effect on the camera module 50.

[0039] It should also be noted that the inventor has also conceived other ideas, using a slender camera module 50 to replace the conventional camera module 50, and the slender camera module 50 can extend from the opening on the middle plate 11 to the front side of the middle plate 11, so that while the middle plate on the electronic device of the related art provides support for the camera module 50, the distance between the camera module 50 and the display screen 20 can be reduced to increase the screen-to-body ratio of the electronic device 100. However, the slender camera module 50 needs to be customized, resulting in an increase in the manufacturing cost of the electronic device 100.

[0040] Compared with the implementation scheme in which the electronic device 100 adopts a slender camera module 50, the camera module 50 in the electronic device 100 of this embodiment does not need to be specially slender, so the camera module 50 does not need to be customized, which helps to avoid an increase in the manufacturing cost of the electronic device 100 and is beneficial to improving the product competitiveness of the electronic device 100.

[0041] In addition, in the technical solutions of some related electronic devices in which the camera module is arranged on the middle plate and the shell presses down the camera module, the installation position of the camera module 50 depends on the manufacturing tolerance of the middle plate 11, the manufacturing tolerance of the shell 40, the assembly tolerance between the camera module 50 and the middle plate 11, and the assembly tolerance between the camera module 50 and the shell 40. It can be seen that the dimension chain of the camera module 50 assembled inside the electronic device 100 is relatively long. In the electronic device 100 of this embodiment, because the fixed end of the camera module 50 is connected to the support plate 13 of the middle frame 10, the installation position of the camera module 50 depends on the manufacturing tolerance of the support plate 13 and the assembly tolerance between the camera module 50 and the support plate 13, the installation position of the camera module 50 is not affected by the shell 40, and the dimension chain of the camera module 50 assembled inside the electronic device 100 is shortened. As a result, the assembly accuracy and production yield of the electronic device 100 are improved.

[0042] The above-mentioned shell 40 and the middle frame 10 together form a cavity. The electronic device 100 may also include a battery, which is used to provide power for the display screen 20, the camera module 50, etc. In some embodiments, the electronic device 100 may also include a back cover, which is arranged on the rear side of the shell 40 and connected to the shell 40. The battery may be arranged in the cavity surrounded by the shell 40 and the back cover. In this technical solution, when the back of the electronic device 100 hits the ground or the user presses the back of the electronic device 100, there is an external force F acting on the back cover, and the external force F is then transmitted to the shell 40, and then to the middle frame 10. As some optional embodiments, the battery may also be arranged in the cavity, and the shell 40 at this time can serve as the back cover of the electronic device 100. In this technical solution, when the back of the electronic device 100 hits the ground or the user presses the back of the electronic device 100, there is an external force F directly acting on the shell 40.

[0043] Understandable, such as Figure 3 and Figure 4 As shown, the housing 40 may be in contact with the support plate 13. At this time, if the housing 40 is subjected to an external force F, the external force F is transmitted to the support plate 13. Alternatively, in other embodiments, there may be a certain distance between the housing 40 and the support plate 13. At this time, if the housing 40 is subjected to an external force F, the external force F is transmitted to the middle frame 10 from the connection between the housing 40 and the middle frame 10.

[0044] Exemplarily, the shell 40 can be made of metal materials such as aluminum alloy or ceramic materials or glass materials. In an alternative embodiment, the material of the shell 40 includes at least glass fiber. In addition to glass fiber, the material of the shell 40 may also include plastic. In this embodiment, metal materials, ceramic materials and glass fiber materials all have the advantage of high strength, so the shell 40 has a strong ability to resist deformation, which is conducive to reducing the possibility of the shell 40 being squeezed by external forces and squeezing the middle frame 10, thereby reducing the risk of the camera module 50 squeezing the display screen 20.

[0045] Similarly, the middle frame 10 can also be made of metal materials such as aluminum alloy or made of ceramic materials and glass materials. Alternatively, the material of the middle frame 10 includes at least glass fiber. In addition to glass fiber, the material of the middle frame 10 may also include plastic. In this case, the middle frame 10 can be injection molded by an aluminum alloy mold. In this embodiment, metal materials, ceramic materials, and glass fiber materials all have the advantage of high strength, so the middle frame 10 has strong deformation resistance, which is conducive to reducing the possibility of the middle frame 10 being affected by external forces to squeeze the camera module 50, and helps to further reduce the risk of the camera module 50 squeezing the display screen 20. In addition, in the implementation scheme where the material of the shell 40 and the middle frame 10 includes glass fiber, the shell 40 and the middle frame 10 will not shield the signal of the electronic device 100.

[0046] In some embodiments, please combine Figure 2 and Figure 4 The electronic device 100 also includes a mainboard 70 and a circuit board 60. The mainboard 70 is installed in the cavity. The mainboard 70 mainly plays the role of processing signals and controlling. An avoidance hole is formed on the annular enclosure 12. Part of the circuit board 60 is located in the cavity and connected to the mainboard 70. One end of the circuit board 60 extends into the installation space through the avoidance hole and is connected to the camera module 50. In this way, the mainboard 70 and the circuit board 60 communicate with each other, and the mainboard 70 can control the camera module 50. Here, the circuit board 60 can be specifically connected to the mainboard 70 through a connector, wherein the connector can be, for example, a board-to-board connector (board to board, BTB), and the board-to-board connector includes a male seat arranged on the circuit board 60 and a female seat arranged on the mainboard 70, and the male seat is connected to the female seat by buckling.

[0047] It should be understood that after the transparent cover plate 30 is installed on the display screen 20, the assembly process of the electronic device 100 of this embodiment may also include the following steps: providing a circuit board 60, moving the circuit board 60 to the rear side of the middle plate 11, and extending one end of the circuit board 60 from the avoidance hole into the installation space to connect with the camera module 50; providing a main board 70, moving the main board 70 to the rear side of the middle plate 11, and connecting the main board 70 to the circuit board 60; providing a shell 40, moving the shell 40 to the rear side of the middle frame 10, and connecting the middle frame 10 to the shell 40.

[0048] Through the above arrangement, the avoidance hole on the annular enclosure 12 can allow the circuit board 60 to pass through, ensuring that the camera module 50 accommodated in the installation space can be connected to the main board 70 through the circuit board 60, thereby realizing the control of the camera module 50.

[0049] Among them, in some implementations, the avoidance hole can be set between the end faces of the annular enclosure 12 at both ends along the extension direction Z of the central axis of the inner hole. In this method, the shape of the avoidance hole is not limited to regular shapes such as circular, rectangular, elliptical, etc., and can also be an irregular shape. In other implementations, such as Figure 4 As shown, along the extension direction Z of the central axis of the inner hole, the avoidance hole passes through the end surface of the annular enclosure 12 away from the display screen 20, so that the height of the annular enclosure 12 along the extension direction Z of the central axis of the inner hole is not equal everywhere.

[0050] In some embodiments, Figure 3 and Figure 4 As shown, the lens end of the camera module 50 does not protrude from the first surface of the middle plate 11. In this way, there is a gap between the lens end of the camera module 50 and the display screen 20, which is conducive to further reducing the risk of the camera module 50 being squeezed and hitting the display screen 20. There may also be a gap between the first surface of the middle plate 11 and the side of the display screen 20 facing the middle plate 11, so as to prevent the middle frame 10 from squeezing the display screen 20 under the action of external force.

[0051] As an optional example, the electronic device 100 further includes an elastic member 80, the elastic member 80 includes a sealing ring 81 and an elastic ring 82, the sealing ring 81 is nested between the camera module 50 and the inner circumference of the annular enclosure 12, the elastic ring 82 is connected to one end of the sealing ring 81, the elastic ring 82 is located between the camera module 50 and the display screen 20, and the elastic ring 82 is against the lens end of the camera module 50. With this design, the sealing ring 81 of the elastic member 80 can play a sealing role to block the annular gap 14 formed between the camera module 50 and the inner circumference of the annular enclosure 12, so that when installing components such as the circuit board 60, the main board 70, and the housing 40, dust can be prevented from entering the inside of the electronic device 100 through the annular gap 14, thereby helping to prevent dust from falling on the display screen 20. Moreover, the elastic ring 82 of the elastic member 80 can play a buffering role. If an external force is transmitted to the camera module 50 , the camera module 50 squeezes the elastic ring 82 , and the elastic ring 82 can be compressed and deformed, further avoiding the possibility of the camera module 50 hitting the display screen 20 .

[0052] Exemplarily, the sealing ring 81 may be interference fit with the annular gap 14. In this embodiment, after the fixed end of the camera module 50 is fixedly connected to the support plate 13 and before the display screen 20 is provided, the assembly process of the electronic device 100 also includes the following steps: providing an elastic member 80, moving the elastic member 80 to the front side of the middle plate 11, and aligning the sealing ring 81 with the annular gap 14; moving the elastic member 80 so that the sealing ring 81 is embedded in the annular gap 14; and continuing to apply force to the elastic member 80 until the elastic ring 82 abuts against the lens end of the camera module 50. Here, by designing the sealing ring 81 to have an interference fit with the annular gap 14, the sealing ring 81 can be stably installed between the annular enclosure 12 and the camera module 50 to ensure the installation stability of the elastic member 80.

[0053] In some embodiments, Figure 3 and Figure 4 As shown, the elastic ring 82 includes a first ring body 821 and a second ring body 822 . The second ring body 822 is protruding toward the front side of the middle plate 11 and is disposed on the first ring body 821 . The second ring body 822 extends into the viewing window 21 .

[0054] Exemplarily, the side of the first annular body 821 facing the display screen 20 is flush with the first surface. In this way, in the technical solution in which there is a gap between the first surface of the middle plate 11 and the side of the display screen 20 facing the middle plate 11, there is also a gap between the side of the first annular body 821 facing the display screen 20 and the side of the display screen 20 facing the middle plate 11. In this example, the risk of the middle plate 11 and the first annular body 821 squeezing the display screen 20 can be reduced at the same time. At the same time, there is a gap between the outer peripheral surface of the second annular body 822 and the hole wall of the window hole 21, so as to prevent the second annular body 822 from squeezing the display screen 20. Among them, the second annular body 822 can also abut against the side of the transparent cover plate 30 facing the display screen 20.

[0055] It should be noted that, in order to prevent the camera module 50 from being blocked by the elastic ring 82 and affecting the shooting, the field of view of the camera module 50 is located in the light-transmitting space surrounded by the inner surface of the elastic ring 82. As a feasible method, Figure 3 and Figure 4 As shown, the inner surface of the elastic ring 82 is a conical surface, and along the thickness direction Z of the display screen 20, the cross-sectional area of ​​the conical surface gradually increases from one end of the elastic ring 82 close to the camera module 50 to the other end away from the camera module 50, and the cone angle α of the conical surface is equal to the field of view angle γ of the camera module 50. This design can not only ensure that the elastic ring 82 does not block the field of view of the camera module 50, but also make the light-transmitting space surrounded by the inner surface of the elastic ring 82 as small as possible, so that the volume of the elastic ring 82 is as large as possible, so as to ensure that the elastic ring 82 has a high deformation ability, and strengthen the protective effect of the elastic ring 82 on the camera module 50.

[0056] In any of the above embodiments, a portion of the transparent cover plate 30 facing the display screen 20 corresponding to the window hole 21 is recessed to form an arc surface 33, and the arc surface 33 is located within the field of view of the camera module 50. In this example, the arc surface 33 can act as a convex lens on the object side of the camera module 50. With this design, the camera module 50 of this embodiment can save a convex lens while still achieving the shooting effect when equipped with the above convex lens, so the structure of the camera module 50 is simpler, which is conducive to reducing the material cost of the camera module 50.

[0057] As another alternative embodiment, a part of the transparent cover plate 30 facing the display screen 20 corresponding to the window hole 21 may also be convex to form an arc surface, and the arc surface is also located within the field of view of the camera module 50. In this example, the arc surface can act as a concave lens on the object side of the camera module 50. In this way, the camera module 50 can save a concave lens while still achieving the shooting effect when equipped with the above-mentioned concave lens, so the structure of the camera module 50 is simpler, which is conducive to reducing the material cost of the camera module 50.

[0058] Moreover, since the camera module 50 in the electronic device 100 of this embodiment can omit a lens, the height of the camera module 50 can be reduced, and the distance between the fixed end of the camera module 50 and the display surface of the display screen 20 can be reduced along the thickness direction Z of the electronic device 100 without changing the field of view of the camera module 50. Therefore, without changing the distance between the side of the support plate 13 facing away from the display screen 20 and the display surface of the display screen 20, the thickness of the support plate 13 can be further increased, and the strength of the support plate 13 can be further improved. In this way, the supporting effect of the support plate 13 on the camera module 50 is improved, and the risk of the camera module 50 hitting the display screen 20 is greatly reduced.

[0059] For example, the thickness of the support plate 13 may be greater than or equal to 8 mm, so that the support plate 13 can reliably support the camera module 50. Similarly, the thickness of the middle plate 11 and the thickness of the annular surrounding plate 12 may also be greater than or equal to 8 mm.

[0060] The preferred embodiments of the present disclosure are described above with reference to the accompanying drawings, but the scope of the present disclosure is not limited thereby. Any modification, equivalent substitution and improvement made by those skilled in the art without departing from the scope and essence of the present disclosure shall be within the scope of the present disclosure.
