Description

Camera components and electronic equipment

Technical Field

The present application relates to the technical field of electronic devices, and specifically to camera components and electronic devices.

Background technique

As consumers' requirements for the screen-to-body ratio of electronic devices continue to increase, researchers have proposed screen structure solutions such as narrow bezels, notch screens, water drop screens, and hole-punch screens (including through holes and blind holes) to improve the screen-to-body ratio of electronic devices; there are also composite solutions that introduce mechanical telescopic structures and then match them with traditional front-facing cameras; or there are dual-screen solutions that only retain the rear camera, which is used as both the front and rear cameras; or even flip-structure cameras that flip the rear camera to use as the front camera. The design purpose of all the above structural solutions is to further increase the screen-to-body ratio of electronic devices in order to obtain a wider field of view experience.

Among them, structures such as the notch screen and the water drop screen cause great damage to the screen, and the screen cost will be relatively high; moreover, the visual beauty of the integrated screen is destroyed, which is unacceptable to some consumers. Other full-screen solutions (such as telescopic structure camera, dual-screen solution with only the rear screen and the flip camera solution) have higher requirements for the whole machine, increase the structural complexity, and make the stacking and detailed design of the whole machine more difficult, and the cost will also increase accordingly. Although the design of narrow bezels and hole-punch screens is used in many electronic devices, which can make the whole machine more integrated, it is limited by the size of the front camera and the different assembly methods, and the screen-to-body ratio is relatively small compared to other solutions, which has been difficult to break through.

Detailed ways

The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by those of ordinary skill in the art without making creative work are within the scope of protection of the present application.

Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

As used herein, a "communication terminal" (or simply "terminal") includes, but is not limited to, a device configured to receive/send communication signals via a wireline connection (e.g., via a public switched telephone network (PSTN), a digital subscriber line (DSL), a digital cable, a direct cable connection, and/or another data connection/network) and/or via a wireless interface (e.g., for a cellular network, a wireless local area network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and/or another communication terminal). A communication terminal configured to communicate via a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal" or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular phones; personal communication system (PCS) terminals that may combine cellular radiotelephones with data processing, fax, and data communication capabilities; PDAs that may include radiotelephones, pagers, Internet/Intranet access, web browsers, notepads, calendars, and/or global positioning system (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include radiotelephone transceivers. A mobile phone is a mobile terminal configured with a cellular communication module.

The technical solution of this application is mainly aimed at improving the structure of full-screen such as narrow bezels and punch-hole screens, so as to further narrow the black borders around the cameras of narrow bezels and punch-hole screens, thereby increasing the screen-to-body ratio of electronic devices. The technical solution for narrow bezels is mainly to achieve the purpose of "small head" (reducing the non-display area at the top of the electronic device), while the technical solution for punch-hole screens is mainly to achieve the purpose of reducing the black borders around the cameras.

For the technical solution of narrow frame, the relevant technical means generally adopt the structural design shown in Figure 1. Figure 1 is a schematic diagram of the structure of an embodiment of an electronic device with narrow frame, in which the front camera 11 is sealed and dustproof by foam 12 and glass cover 13; at the same time, the foam 12 is also used to block the light emitted by the display screen 14 to prevent the light emitted by the display screen 14 from being projected into the camera to produce "ghost images". Further, the range shown in A in Figure 1 can represent the non-display area of the display screen 14, and the width of the A area is generally 0.95-1.5mm. The range shown in B in Figure 1 can represent the gap between the display screen 14 and the camera 11. Due to the large size of the foam 12 and the need to reserve the assembly gap between the camera 11 and the display screen 14, the minimum width of the B area can only be 0.8-0.9mm. The range shown in C in Figure 1 can represent the gap between the camera 11 and the edge of the glass cover 13. Therefore, the width (A+B+C) in Figure 1 can represent the size of the black border of the electronic device. In the full-screen design with narrow bezels, the main goal is to minimize the width of (A+B+C) to increase the screen-to-body ratio of the electronic device.

Please refer to FIG. 2 and FIG. 3 , FIG. 2 is a partial side view of an electronic device according to an embodiment of the present application, and FIG. 3 is a bottom view of the electronic device in FIG. 2 along the X direction.

It should be noted that the electronic device in the embodiment of the present application can be a terminal device with a camera, such as a mobile phone, a tablet computer, a laptop computer, a wearable device, etc. The electronic device includes but is not limited to a transparent cover plate 100, a housing 200, a display screen 300, a camera module 400, and a shading structure 500. Among them, the housing 200 is connected to the transparent cover plate 100, and together they are enclosed to form a receiving space (not marked in FIG. 2), and the display screen 300, the camera module 400, the shading structure 500 and other structural parts are all arranged in the receiving space. Furthermore, in the diagram of the electronic device structure in the embodiment of the present application and the description of the components, only the structural components related to the present application are given; other structural parts of the electronic device (such as circuit boards, processors, etc.) will not be specifically introduced in this application.

The transparent cover 100 includes a first surface 110 and a second surface 120 which are arranged opposite to each other. Among them, the material of the transparent cover 100 can be glass or transparent resin, corresponding to a rigid screen or a flexible screen. The display screen 300 is attached to the first surface 110 of the transparent cover 100, which can reduce the thickness of the electronic device and increase the touch sensitivity of the display screen 300. Among them, the area of the display screen 300 is smaller than the area of the first surface 110, so that the transparent cover 100 can completely cover the display screen 300, thereby protecting the display screen 300. The second surface 120 of the transparent cover 100 serves as the outer surface of the electronic device for consumers to interact with the electronic device, and can be used to receive touch operations such as clicks and slides from users. Of course, in some other embodiments, the second surface 120 can also be provided with other film layers such as tempered film, frosted film, decorative film, anti-peep film, hydrogel film, etc., so that the electronic device provides consumers with different experience effects.

The terms "first" and "second" in this application are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

The camera module 400 and the display screen 300 are arranged on the same side of the transparent cover plate 100, for example, both are arranged on the side close to the first surface 110; and the camera module 400 and the display screen 300 are arranged side by side and adjacent to each other. Further, the camera module 400 includes a fixing seat 410 and a lens 420. The fixing seat 410 can be used for the installation and fixation of the camera module 400, for example, the camera module 400 is fixed to the housing 200 through the fixing seat 410. The lens 420 can be arranged toward the first surface 110 of the transparent cover plate 100, so as to directly collect the ambient light passing through the transparent cover plate 100, so that the electronic device can realize functions such as face recognition, taking pictures, and payment through the camera module 400. Of course, in some other embodiments, the lens 420 may not be arranged toward the first surface 110 of the transparent cover plate 100. For example, by setting a prism between the lens 420 and the transparent cover plate 100, the ambient light passing through the transparent cover plate 100 can be reflected to the lens 420, which can also enable the electronic device to realize the above functions.

Furthermore, a first extension surface 430 is provided on one side of the fixing base 410 connected to the lens 420, and a second extension surface 440 is provided on the other side of the fixing base 410 connected to the lens 420. The second extension surface 440 and the first extension surface 430 are located on opposite sides of the lens 420, as shown in FIG2 .

In this embodiment, the display screen 300 abuts against the first extension surface 430 and the side of the lens 420, as shown in FIG2 , thereby reducing the distance between the camera module 400 and the display screen 300 to an extremely small size, thereby increasing the screen-to-body ratio of the electronic device; the thickness of the electronic device can also be reduced. Theoretically, if the processing accuracy and assembly accuracy allow, the distance between the camera module 400 and the display screen 300 can be zero, which will greatly reduce the size of the black border of the electronic device, thereby greatly increasing the screen-to-body ratio of the electronic device.

The range shown by Q1 in FIG. 3 can represent the black border area of the electronic device, that is, the area from the dotted line to the edge of the transparent cover 100, that is, the non-displayable area observed on the front panel of the electronic device. The range shown by Q2 in FIG. 3 can represent the area between the display screen 300 and the edge of the transparent cover 100. Among them, the difference between Q1 and Q2, that is, the range shown by (Q1-Q2), can represent the non-display area 310 of the display screen 300, which is generally used to set the wiring structure of the display screen 300.

Please refer to Figure 2 again. The range shown in D in Figure 2 (that is, the range shown in (Q1-Q2) in Figure 3) can represent the non-display area 310 of the display screen 300 (generally 0.95-1.5 mm). This width is generally determined by the structure of the display screen 300 itself and is not within the scope of discussion of this embodiment; accordingly, other areas of the display screen 300 except the above-mentioned non-display area 310 can represent the display area 320, so that consumers can interact with electronic devices. In some embodiments, the display area 320 and the non-display area 310 are arranged adjacent to each other, which can correspond to a narrow frame. In some other embodiments, the display area 320 is partially arranged around the non-display area 310, which can correspond to a bangs screen or a water drop screen. In other embodiments, the display area 320 is completely arranged around the non-display area 310, which can correspond to a hole-punch screen. The range shown in E in Figure 2 can represent the gap between the camera module 400 and the display screen 300. Among them, in this embodiment, the display screen 300 is in contact with the first extension surface 430 and the side of the lens 420, that is, the non-display area 310 of the display screen 300 overlaps with the first extension surface 430; theoretically, the width of E can be minimized to 0. The range shown by F in Figure 2 can represent the width from the camera module 400 to the edge of the transparent cover 100. Therefore, the width (D+E+F) in Figure 2 can represent the size of the black border of the electronic device (that is, Q1 in Figure 3). In the full-screen design scheme with a narrow frame, the main purpose is to minimize the width (D+E+F) to increase the screen-to-body ratio of the electronic device.

Further, the shading structure 500 is arranged between the camera module 400 and the transparent cover plate 100. On the one hand, the shading structure 500 can be used to block the light emitted by the display screen 300 to prevent the light emitted by the display screen 300 from interfering with the camera module 400, that is, to eliminate the "ghost" phenomenon of the camera module 400. On the other hand, for the lens 420, the shading structure 500 can also play the role of a diaphragm. Among them, the diaphragm refers to an entity that restricts the light beam in the optical system; according to different application scenarios and requirements, there are mainly aperture diaphragms, field diaphragms, vignetting diaphragms, stray light elimination diaphragms, etc. Of course, the lens 420 itself can also be provided with the above-mentioned diaphragm. In this embodiment, the shading structure 500 can be located within the black border area Q1 of the electronic device, as shown in Figures 2 and 3. At this time, the influence of the width of the shading structure 500 on the screen-to-body ratio of the electronic device can be almost ignored, and the diaphragm effect of the shading structure 500 on the lens 420 can be considered more.

Please refer to FIG. 4 and FIG. 5 together. FIG. 4 is a side view structural diagram of an embodiment of the camera module in FIG. 2 , and FIG. 5 is a top view structural diagram of the camera module in FIG. 4 .

The light shielding structure 500 is arranged in a ring shape and is arranged on the side of the lens 420 facing the transparent cover plate 100, and the light shielding structure 500 is arranged coaxially with the lens 420. Furthermore, the light shielding structure 500 and the lens 420 can be integrally formed by two-color injection molding, so that the light shielding structure 500 can support the transparent cover plate 100, thereby increasing the sealing between the light shielding structure 500 and the transparent cover plate 100, thereby preventing the light emitted by the display screen 300 from "leaking" to the lens 420. In addition, the material of the light shielding structure 500 can be soft rubber, such as liquid silicone or thermoplastic polyurethane elastomer rubber (such as TPU, etc.), so that the lens 420 and the transparent cover plate 100 change from rigid contact to flexible contact. The width W1 of the light shielding structure 500 can be 0.1-0.5mm, and further can be 0.1-0.3mm; and the width W1 of the light shielding structure 500 in this embodiment can be 0.1mm or 0.2mm. Furthermore, the compressive deformation of the light shielding structure 500 holding the first surface 110 of the transparent cover plate 100 is 0.05-0.1mm, that is, the light shielding structure 500 is in a state of micro-compressive deformation. The above-mentioned compressive deformation is the dimensional deformation of the light shielding structure 500 in the direction perpendicular to the first surface 110 of the transparent cover plate 100 (that is, the thickness direction of the electronic device); that is, the pre-interference amount between the light shielding structure 500 and the transparent cover plate 100 when the camera module 400 is assembled to the electronic device, which is required to ensure that the light shielding structure 500 is pressed or reliably held on the first surface 110 of the transparent cover plate 100.

In some other embodiments, the light shielding structure 500 may be a light shielding glue, which may be formed on at least one of the transparent cover plate 100, the lens 420, and the non-display area 310 of the display screen 300 by dispensing or the like. In other embodiments, the light shielding structure 500 may also be a light shielding tape or a light shielding ink layer, and the light shielding tape is at least attached to at least one of the transparent cover plate 100, the lens 420, and the non-display area 310 of the display screen 300, or the light shielding ink layer is at least coated on at least one of the transparent cover plate 100, the lens 420, and the non-display area 310 of the display screen 300.

Please refer to Figure 2 again. E in Figure 2 is the assembly gap between the display screen 300 and the camera module 400, and the assembly gap serves as a reserved gap when assembling the camera module 400. Among them, the size of the assembly gap E can be set between 0.1-0.5mm. It can be seen from the relevant description in Figure 1 above that in order to set the foam 12 in the related technology, a larger assembly gap is required (the minimum can only be 0.8-0.9mm). In comparison, this embodiment can reduce the width of the black border by more than 0.5mm by setting the shading structure 500 on the side of the lens 420 close to the transparent cover plate 100, thereby reducing the size of the assembly gap E between the camera module 400 and the display screen 300 in Figure 2, thereby increasing the screen-to-body ratio of the electronic device.

Please refer to FIG. 6 and FIG. 7 , FIG. 6 is a side view structural diagram of another embodiment of the camera module in FIG. 2 , and FIG. 7 is a top view structural diagram of the camera module in FIG. 6 .

Different from the above-mentioned embodiment, the lens 420 of the camera module 400 of this embodiment is provided with two annular light shielding structures 500 (a first light shielding structure 510 and a second light shielding structure 520) on one side close to the transparent cover plate 100. Through the design of this double light shielding structure, double assurance can be achieved to ensure the reliability of the light shielding effect.

Among them, the height of the first shading structure 510 and the second shading structure 520 (the minimum distance between its vertex and the lens 420, not marked in the figure) can be set to a difference. For example: the previous embodiment records that the compression deformation of the shading structure 500 can be 0.05-0.1mm. Then, the height difference between the first shading structure 510 and the second shading structure 520 of this embodiment can be set to half of the above-mentioned compression deformation, that is, 0.025-0.05mm. In this way, it can be ensured that at least one of the first shading structure 510 and the second shading structure 520 is in contact with the first surface 110 of the transparent cover 100. In addition, when any one of the first shading structure 510 and the second shading structure 520 is damaged or fails, the other can continue to support the first surface 110 of the transparent cover 100, thereby ensuring the reliability of shading.

Furthermore, other structures of this embodiment are the same as or similar to any of the above embodiments and will not be described in detail here.

Please refer to FIG. 8 and FIG. 9 , FIG. 8 is a schematic diagram of the side structure of an embodiment of the transparent cover plate in FIG. 2 , and FIG. 9 is a schematic diagram of the bottom structure of the transparent cover plate in FIG. 8 .

This embodiment mainly further improves the structure of the transparent cover plate 100 and the structural coordination between the light shielding structure 500 and the transparent cover plate 100. Among them, the first surface 110 of the transparent cover plate 100 is provided with a sinking groove 111, and the annular opaque sheet (i.e., the light shielding structure 500) is attached to the sinking groove 111. Furthermore, the depth of the sinking groove 111 can be reasonably designed according to the thickness of the transparent cover plate 100 and the overall strength of the transparent cover plate 100, and can also be greater than the thickness of the light shielding structure 500.

Please refer to Figures 8 to 10 together. Figure 10 is a schematic diagram of the structure in which the sink groove opened on the first surface of the transparent cover plate in Figure 8 is provided with a light-shielding structure. The advantage of this structural design is that it can reduce the gap between the camera module 400 and the transparent cover plate 100, so that the camera module 400 can be closer to the transparent cover plate 100, thereby achieving the purpose of reducing the thickness of the electronic device. Of course, in some other embodiments, the light-shielding ink layer can also be applied to the sink groove 111, and the light-shielding glue can also be formed on the sink groove 111 by dispensing or the like; and the structure of the sink groove 111 is not limited to the annular structure in this embodiment, and can also be other shapes.

Furthermore, other structures of this embodiment are the same as or similar to any of the above embodiments and will not be described in detail here.

Please refer to FIG. 11 , which is a partial side structural diagram of another embodiment of the electronic device provided in the present application.

This embodiment is mainly aimed at further improving the structure of the display screen 300. Among them, the display screen 300 is bent in the direction away from the transparent cover plate 100 at the side close to the camera module 400. Specifically, the non-display area 310 is bent in the direction away from the transparent cover plate 100; and the end face of the non-display area 310 can abut against the first extension surface 430. The advantage of this structural design is that by bending the non-display area 310 of the display screen 300, the size of D in Figure 11 can be further reduced. Any of the above embodiments is mainly to reduce the size of E in Figure 11. In this embodiment, the sizes of D and E in Figure 11 are reduced at the same time, which further reduces the size of the black border (D+E+F) of the electronic device, thereby further increasing the screen-to-body ratio of the electronic device.

Furthermore, other structures of this embodiment are the same as or similar to any of the above embodiments and will not be described in detail here.

Please refer to FIG. 12 and FIG. 13 . FIG. 12 is a partial side view of another embodiment of the electronic device provided by the present application. FIG. 13 is a bottom view of the electronic device in FIG. 12 along the X direction.

This embodiment is mainly aimed at further improving the structure of the camera module 400, specifically, improving the structure of the fixing seat 410. Among them, the width of the second extension surface 440 is smaller than the width of the first extension surface 430, as shown in Figures 12 and 13, so that the fixing seat 410 is an irregular structure. The advantage of this structural design is that by partially reducing the structural size of the fixing seat 410, the fixing seat 410 can not only meet the installation and fixing requirements of the camera module 400, but also make the camera module 400 as a whole closer to the middle frame part of the shell 200, thereby reducing the size of F in Figure 12, so as to achieve the purpose of further reducing the size of the black border, thereby increasing the screen ratio of the electronic device.

Optionally, the side of the lens 41 away from the display screen 300 is coplanar with the side of the fixing base 410 away from the display screen 300, so that the width of the second extension surface 440 is 0, so that the side of the camera module 400 away from the display screen 300 is flush with the end surface of the transparent cover 100. At this time, the value of the F dimension in Figure 12 is the size of the lens 420. For example: if a lens 420 with a diameter of 3.5 mm is selected, then F in Figure 12 can be made 3.5 mm.

Furthermore, other structures of this embodiment are the same as or similar to any of the above embodiments and will not be described in detail here.

Please refer to FIG. 14 and FIG. 15 . FIG. 14 is a partial side view of another embodiment of the electronic device provided in the present application. FIG. 15 is a bottom view of the electronic device in FIG. 14 along the X direction.

In this embodiment, an aperture cover 610 is provided on one side of the camera module 400 close to the transparent cover 100, and the camera module 400 and the aperture cover 610 are collectively referred to as a camera assembly 600. The aperture cover 610 can be used to limit the ambient light passing through the transparent cover 100, so that the camera module 400 can obtain different imaging effects; according to different application scenarios and requirements, the aperture cover 610 can be an aperture stop, a field stop, a vignetting stop, a stray light elimination stop, etc.

Optionally, the aperture cover 610 is a separate structural member, and can be detachably connected to the camera module 400 by buckles, threads, adhesives, etc., thereby increasing the diversity of the camera assembly 600, thereby enabling the camera module 400 to achieve more functions. Of course, in some other embodiments, the aperture cover 610 and the camera module 400 (such as the lens 420) can be an integrally formed structural member, which can simplify the assembly process of the camera assembly 600 and increase the compactness of the structure.

Among them, the range shown in G in Figure 14 can represent the non-display area 310 of the display screen 300 (generally 0.95-1.5mm). This width is generally determined by the structure of the display screen 300 itself and is not within the scope of discussion of this embodiment; accordingly, other areas of the display screen 300 except the above-mentioned non-display area 310 can represent the display area 320, so that consumers can interact with electronic devices. The range shown in H in Figure 14 can represent the gap between the camera assembly 600 and the display screen 300. The range shown in I in Figure 14 can represent the width from the camera assembly 600 to the edge of the transparent cover 100. Therefore, the width (G+H+I) in Figure 14 can represent the size of the black border of the electronic device. In the full-screen design scheme with a narrow frame, the main purpose is to minimize the width (G+H+I) to increase the screen-to-body ratio of the electronic device; and this embodiment minimizes the two dimensions H and I.

After long-term research, the inventor of the present application found that for the aperture cover 610 and the camera module 400 integrally formed structural component, the diameter of the lens 420 is generally greater than 3 mm. However, if the aperture cover 610 and the camera module 400 are separated and separated into two separate structural components, the diameter of the lens 420 can be less than 3 mm without affecting the imaging effect of the camera module 400, which provides a possibility for further increasing the screen-to-body ratio of the electronic device.

On the one hand, this embodiment further improves the structure of the camera assembly 600, specifically, the structure of the aperture cover 610. Among them, the aperture cover 610 and the camera module 400 are two separate structural parts, and the aperture cover 610 can be covered on the camera module 400; and the diameter of the lens 420 of the camera module 400 can be less than or equal to 3mm. The advantage of this structural design is that by peeling the aperture cover 610 from the camera module 400, the lens 420 of the camera module 400 can be made smaller, thereby reducing the size of I in Figure 14, so as to further reduce the size of the black border, thereby increasing the screen-to-body ratio of the electronic device.

Please refer to FIG. 14 to FIG. 16 , FIG. 16 is a schematic structural diagram of an embodiment of the aperture cover in FIG. 14 .

The aperture cover 610 includes a connecting portion 611 and a functional portion 612. The connecting portion 611 is used to connect with the camera module 400, specifically, it can be connected with the lens 420 of the camera module, or connected with the lens 420 of the camera module 400 and the fixing seat 410 at the same time; so that the aperture cover 610 and the camera module 400 can form a structural component. The functional portion 612 is arranged corresponding to the lens 420 of the camera module 400, and the functional portion 612 is provided with a through hole 613, which serves as a light entrance hole for the lens 420 of the camera module 400, so that the ambient light passing through the transparent cover 100 can reach the lens 420 of the camera module 400. Further, the diameter of the through hole 613 is smaller than the diameter of the lens 420 of the camera module 400, so that the aperture cover 610 plays a role of shielding the lens 420; and the aperture size of the through hole 613 affects the parameters such as the maximum inclination angle and the maximum field of view of the lens 420 imaging to a certain extent.

Optionally, the through hole 613 is coaxially arranged with the lens 420 of the camera module 400, as shown in FIG14, so that the ambient light passing through the transparent cover plate 100 directly passes through the through hole 613 to reach the lens 420, so that the electronic device can realize functions such as face recognition, photo taking, and payment through the camera assembly 600. Of course, in some other embodiments, the through hole 613 may not be coaxially arranged with the lens 420, for example, by providing a prism or other structure between the through hole 613 and the lens 420, the ambient light passing through the through hole 613 can be reflected to the lens 420, so that the electronic device can also realize the above functions.

Furthermore, at least one side of the functional portion 612 is provided with a cutout structure 614, as shown in FIG16 , and the cutout structure 614 serves as an installation avoidance zone for the camera assembly 600. This embodiment is described by taking as an example that the two sides of the functional portion 612 are provided with cutout structures 614 (that is, the functional portion 612 is provided with two cutout structures 614), and any one of the two cutout structures 614 can be used as an avoidance zone for the camera assembly 600 and the display screen 300 to be installed in coordination.

Optionally, the cutout structure 614 forms a hollow structure between the functional portion 612 and the connecting portion 611, so that the cutout structure 614 has a sufficiently large accommodation space, thereby increasing the installation avoidance area of the camera assembly 600. Further, the cutout structure 614 is chamfered or rounded at the junction between the functional portion 612 and the connecting portion 611 to increase the structural strength of the junction, thereby increasing the reliability of the aperture cover 610.

Please refer to FIG. 14 to FIG. 17 , FIG. 17 is a schematic diagram of a top view of the structure of another embodiment of the aperture cover in FIG. 14 .

Different from the above embodiment, the cutout structure 614 near the display screen 300 in this embodiment extends to be tangent to the through hole 613, so that the display screen 300 can be tangent to the light entrance hole of the camera assembly 600. In this way, the size of I in FIG. 14 can be further reduced, thereby achieving the purpose of further reducing the size of the black border, thereby increasing the screen-to-body ratio of the electronic device.

Furthermore, other structures of this embodiment are the same as or similar to those of the above embodiments and will not be described in detail here.

Referring again to FIG. 14 and FIG. 15 , a part of the structure of the display screen 300 (that is, the non-display area 310) extends to the cutout structure 614. At this time, the projection of the camera assembly 600 on the first surface 110 of the transparent cover plate 100 at least partially overlaps with the projection of the display screen 300 on the first surface 110 of the transparent cover plate 100. Specifically, the projection of the connecting portion 611 on the first surface 110 of the transparent cover plate 100 at least partially overlaps with the projection of the non-display area 310 on the first surface 110 of the transparent cover plate 100, so as to reduce the size of I in FIG. 14, thereby achieving the purpose of further reducing the size of the black border, thereby increasing the screen-to-body ratio of the electronic device.

Furthermore, a shading structure 500 is provided between the display screen 300 and the camera assembly 600, and the shading structure 500 is used to block the light emitted by the display screen 300 to prevent the light emitted by the display screen 300 from interfering with the camera assembly 600. Since the aperture cover 610 can be a hollow structure, the shading structure 500 is mainly arranged on the display screen 300 and its vicinity. Specifically, the non-display area 310 includes a first contact surface 311, a second contact surface 312 and a side surface 313 connecting the first contact surface 311 and the second contact surface 312, and the first contact surface 311 is arranged close to the transparent cover plate 100. Among them, the shading structure 500 is arranged between the first contact surface 311 and the transparent cover plate 100 and on the side surface 313.

Optionally, the material of the light shielding structure 500 between the first contact surface 311 and the transparent cover plate 100 and the side surface 313 is soft rubber, such as liquid silicone or thermoplastic polyurethane elastomer rubber, so that the display screen 300 and the transparent cover plate 100 and the aperture cover 610 change from rigid contact to flexible contact. In this way, the light shielding structure 500 can support the transparent cover plate 100, the display screen 300 and the aperture cover 610. On the one hand, the light shielding structure 500 can increase the sealing between the transparent cover plate 100, the display screen 300 and the aperture cover 610, thereby preventing the light emitted by the display screen 300 from "leaking" to the camera module 400; on the other hand, it can also play a role of flexible buffering between the three. Optionally, the hardness of the material of the light shielding structure 500 can be less than the hardness of the material of the aperture cover 610. Of course, in some other embodiments, the hardness of the two can also be the same or similar. The material of the aperture cover 610 may also be resin, plastic or rubber, etc., which is not specifically limited here, as long as it can be reliably connected to the camera module 400 and conveniently assembled.

Optionally, in this embodiment, the compressive deformation of the shading structure 500 holding the transparent cover plate 100 can be 0.05-0.1mm, that is, the shading structure 500 is in a state of micro-compressive deformation. As an embodiment of a reliable and practical product, the compressive deformation of the shading structure 500 in this implementation can be 0.08mm. Among them, the above-mentioned compressive deformation can be the dimensional deformation of the shading structure 500 in the direction perpendicular to the transparent cover plate 100 (that is, the thickness direction of the electronic device). Further, the width of the shading structure 500 is less than or equal to 0.3mm, thereby minimizing the H dimension in Figure 14. In this embodiment, the width of the shading structure 500 can be 0.1-0.3mm, and further can be 0.1-0.2mm. As an embodiment of a reliable and practical product, the width of the shading structure 500 in this embodiment can be 0.15mm.

In some other embodiments, the shading structure 500 between the first contact surface 311 and the transparent cover plate 100 and on the side 313 may be a shading glue, which may be formed on the first contact surface 311 and the side 313 of the non-display area 310 of the display screen 300 by dispensing or the like. Among them, the thickness of the shading glue is based on the fact that the light emitted by the display screen 300 can be prevented from "leaking" to the camera module 400. The smaller the thickness of the shading glue, the better. This can not only reduce the H dimension in FIG. 14, but also reduce the thickness of the electronic device. In other embodiments, the shading structure 500 between the first contact surface 311 and the transparent cover plate 100 and on the side 313 may also be a shading tape or a shading ink layer. The shading tape is attached to the non-display area 310 of the display screen 300, or the shading ink layer is coated on the non-display area 310 of the display screen 300. Among them, the thickness of the light-shielding tape or the light-shielding ink layer is based on the fact that it can prevent the light emitted by the display screen 300 from "leaking" to the camera module 400. The smaller the thickness of the light-shielding tape or the light-shielding ink layer, the better. This can not only reduce the H dimension in Figure 14, but also reduce the thickness of the electronic device. Of course, in other embodiments, the light-shielding structure 500 between the first contact surface 311 and the transparent cover plate 100 can be different from that of the side surface 313. For example, the light-shielding structure 500 between the first contact surface 311 and the transparent cover plate 100 is a light-shielding adhesive; the light-shielding structure 500 on the side surface 313 is a light-shielding ink layer.

Please refer to FIG. 18 , which is a partial enlarged structural diagram of another embodiment of the light shielding structure in FIG. 15 .

Different from the above-mentioned embodiment, the light shielding structure 500 between the display screen 300 and the camera assembly 600 of this embodiment is arranged in an arc shape, and the arc-shaped light shielding structure 500 is bent toward the camera assembly 600. The advantage of this structural design is that a better light shielding effect can be achieved by using a shorter light shielding structure 500, that is, reducing the influence of the light emitted by the display screen 300 on the camera assembly 600.

Furthermore, other structures of this embodiment are the same as or similar to those of the above embodiments and will not be described in detail here.

Referring again to FIG. 16 , the functional portion 612 is provided with a light shielding structure 500 on the side facing away from the camera module 400, and the light shielding structure 500 is further used to block the light emitted by the display screen 300 to prevent the light emitted by the display screen 300 from interfering with the camera assembly 600. In this case, the light shielding structure 500 may not be provided in the non-display area 310 (e.g., the first contact surface 311) of the display panel 300, and a better light shielding effect can also be achieved.

The shading structure 500 is arranged in a ring shape and is coaxially arranged with the through hole 613. Furthermore, the shading structure 500 and the functional part 612 can be integrally formed by two-color injection molding, so that the shading structure 500 can support the transparent cover plate 100, thereby increasing the sealing between the shading structure 500 and the transparent cover plate 100, thereby preventing the light emitted by the display screen 300 from "leaking" to the lens 420. In addition, the material of the shading structure 500 can be soft rubber, such as liquid silicone or thermoplastic polyurethane elastomer rubber, so that the lens 420 and the transparent cover plate 100 change from rigid contact to flexible contact. The width of the shading structure 500 can be 0.1-0.5mm, and further can be 0.1-0.3mm; and the width of the shading structure 500 in this embodiment can be 0.1mm or 0.2mm. Furthermore, the compressive deformation of the light shielding structure 500 when holding the first surface 110 of the transparent cover plate 100 is 0.05-0.1mm, that is, the light shielding structure 500 is in a state of micro-compressive deformation. The above-mentioned compressive deformation is the dimensional deformation of the light shielding structure 500 in the direction perpendicular to the first surface 110 of the transparent cover plate 100 (that is, the thickness direction of the electronic device); that is, the pre-interference amount between the light shielding structure 500 and the transparent cover plate 100 when the camera assembly 600 is assembled to the electronic device, which is required to ensure that the light shielding structure 500 is pressed or reliably held on the first surface 110 of the transparent cover plate 100.

Further, the functional part 612 is provided with a positioning retaining wall 614 on the side facing away from the camera module 400, and the positioning retaining wall 614 is provided between the light shielding structure 500 and the through hole 613. The positioning retaining wall 614 is used to limit the positional relationship between the light shielding structure 500 and the through hole 613, so as to prevent the light shielding structure 500 made of soft rubber material from expanding in the direction of the through hole 613 when it is damaged or fails, thereby preventing the through hole 613 from becoming smaller due to the above situation, and further making the field of view of the lens 420 unaffected. In some embodiments, the light shielding structure 500 and the functional part 612 are integrally formed by two-color injection molding. At this time, the height of the positioning retaining wall 614 is less than the height of the light shielding structure 500, so as to prevent the positioning retaining wall 614 from limiting the field of view of the lens 420. In some other embodiments, the positioning retaining wall 614 is arranged around the through hole 613, and the light shielding structure 500 is arranged around the outer periphery of the positioning retaining wall 614 away from the through hole 613. At this time, the shading structure 500 can be a shading tape adhered to the positioning baffle 614, or a shading ink layer coated on the positioning baffle 614; and, as long as the shading structure 500 at least surrounds one half of the positioning baffle 614, the part of the shading structure 500 facing the display screen 300 can obtain a better shading effect.

The following is a brief introduction to electronic devices with hole-punch screens.

Please refer to FIG. 19 and FIG. 20 . FIG. 19 is a partial side view of the structure of an electronic device provided in the present application, and FIG. 20 is a bottom view of the structure of the electronic device in FIG. 19 along the X direction.

The electronic device of this embodiment includes but is not limited to a transparent cover plate 100, a housing 200, a display screen 300, a camera module 400 and a light shielding structure 500. The housing 200 is connected to the transparent cover plate 100 and they are jointly arranged to form a receiving space 210, and the display screen 300, the camera module 400, the light shielding structure 500 and other structural components are all arranged in the receiving space 210.

The transparent cover 100 includes a first surface 110 and a second surface 120 which are arranged opposite to each other. Among them, the material of the transparent cover 100 can be glass or transparent resin, corresponding to a rigid screen or a flexible screen. The display screen 300 is attached to the first surface 110 of the transparent cover 100, which can reduce the thickness of the electronic device and increase the touch sensitivity of the display screen 300. Among them, the display screen 300 is provided with a light-transmitting hole 330, which serves as a light entrance hole for the camera module 400. The second surface 120 of the transparent cover 100 serves as the outer surface of the electronic device for consumers to interact with the electronic device, and can be used to receive touch operations such as clicks and slides from users. Of course, in some other embodiments, the second surface 120 can also be provided with other film layers such as tempered film, frosted film, decorative film, anti-peep film, hydrogel film, etc., so that the electronic device provides consumers with different experience effects.

The camera module 400 and the display screen 300 are arranged on the same side of the transparent cover plate 100, for example, both are arranged on the side close to the first surface 110. In addition, the lens 420 of the camera module 400 is arranged corresponding to the light-transmitting hole 330 and faces the first surface 110 of the transparent cover plate 100. A ring-shaped light-shielding structure 500 is arranged on the side of the lens 420 of the camera module 400 close to the transparent cover plate 100, and the light-shielding structure 500 supports the area of the first surface 110 of the transparent cover plate 100 corresponding to the light-transmitting hole 330. The light-shielding structure 500 is used to block the light emitted by the display screen 300 to prevent the light emitted by the display screen 300 from interfering with the camera module 400.

Optionally, the width of the shading structure 500 can be 0.1-0.5mm, and further can be 0.1-0.3mm; and in this embodiment, the width of the shading structure 500 can be 0.1mm or 0.2mm. Furthermore, the compressive deformation of the shading structure 500 holding the first surface 110 of the transparent cover plate 100 is 0.05-0.1mm. Among them, the compressive deformation mentioned here is the dimensional deformation of the shading structure 500 in the direction perpendicular to the first surface 110 (that is, the thickness of the electronic device); that is, when the camera module 400 is assembled to the electronic device, the pre-interference amount between the shading structure 500 and the transparent cover plate 100 is required to ensure that the shading structure 500 is pressed or reliably held on the first surface 110 of the transparent cover plate 100.

Furthermore, regarding the specific structures of the camera module 400 and the light shielding structure 500 and the relationship between the two, please refer to the relevant description of any of the above embodiments, which will not be repeated here.

The range shown in J in FIG. 19 can represent the non-display area 310 (generally 0.95-1.5 mm) of the display screen 300. This width is generally determined by the structure of the display screen 300 itself and is not within the scope of discussion of this embodiment; accordingly, the display screen 300, except for the non-display area 310, can represent the display area 320 for consumers to interact with the electronic device. The range shown in K in FIG. 19 can represent the assembly gap between the display screen 300 and the camera module 400, which is used as a reserved gap when assembling the camera module 400. Among them, the size of the assembly gap K can be set between 0.1-0.5 mm. It can be seen from the relevant description in FIG. 1 above that in order to set the foam 12 in the related art, a larger assembly gap is required (the minimum can only be 0.8-0.9 mm). In comparison, this embodiment can greatly reduce the size of the assembly gap K between the camera module 400 and the display screen 300 in FIG. 19 by setting the shading structure 500 on the side of the lens 420 close to the transparent cover 100, thereby increasing the screen ratio of the electronic device. The range shown by L in FIG. 19 can represent the size of the black circle of the electronic device (as shown by the dotted line in FIG. 20). Of course, in some other embodiments, the light-transmitting hole 330 can also be of other shapes. This embodiment is just an example of a circular hole as an example. In the full-screen design of the hole-punch screen, the main purpose is to minimize the size of L, thereby increasing the screen-to-body ratio of the electronic device.

Similarly, in this embodiment, an aperture cover (not shown in FIG. 19 ) may be provided on the side of the camera module 400 close to the transparent cover 100, and the aperture cover and the camera module 400 are two separate structural parts, so that the diameter of the lens 420 of the camera module 400 can be less than or equal to 3 mm. The advantage of this structural design is that by peeling the aperture cover from the camera module 400, the lens 420 of the camera module 400 can be made smaller, thereby reducing the size of L in FIG. 19 , and further achieving the purpose of reducing the size of the black circle.

Furthermore, regarding the specific structure of the light shield and the relationship between the light shield and the camera module 400 and the light shielding structure 500, please refer to the relevant description of any of the above embodiments, which will not be repeated here.

Please refer to FIG. 21 , which is a partial side structural diagram of another embodiment of the electronic device provided in the present application.

This embodiment is mainly aimed at further improving the structure of the display screen 300. Among them, the display screen 300 is bent in the direction away from the transparent cover plate 100 at the side close to the camera module 400. Specifically, the non-display area 310 is bent in the direction away from the transparent cover plate 100; and the end face of the non-display area 310 can abut against the first extension surface 430. The advantage of this structural design is that by bending the non-display area 310 of the display screen 300, the size of J in Figure 21 can be further reduced. The above embodiment mainly reduces the size of K in Figure 21. In this embodiment, the sizes of J and K in Figure 21 are reduced at the same time, which further reduces the size L of the black circle of the electronic device, thereby further increasing the screen-to-body ratio of the electronic device.

Furthermore, other structures of this embodiment are the same as or similar to those of the above embodiments and will not be described in detail here.

Please refer to FIG. 22 , which is a partial side structural diagram of another embodiment of the electronic device provided in the present application.

In this embodiment, the camera module 400 is fixed to the housing 200 through the bracket 210. The housing 200 may be a middle frame of an electronic device. Further, the housing 200 is provided with a mounting hole 220, the bracket 210 is embedded in the mounting hole 220, and the camera module 400 is fixedly connected to the bracket 210 and penetrates the mounting hole 220.

Optionally, a foam 230 may be provided between the camera module 400 and the bracket 210. The foam 230 may play a role in vibration reduction on the one hand, and may also play a role in bonding and positioning on the other hand, and is specifically used for positioning the camera module 400 in the up and down directions. The outer diameter of the camera module 400 and the inner diameter of the bracket 210 are matched for positioning to fix the left and right directions of the camera module 400. Furthermore, the bracket 210 and the housing 200 may be snap-fitted or bonded by glue 240.

In this embodiment, all directional indications (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in Figure 22). If the specific posture changes, the directional indication will also change accordingly.

This embodiment can fix the camera module 400 by designing the structure of the housing 200 and the bracket 210. In addition, the housing 200 is provided with a mounting hole 220, and the camera module 400 is inserted into the mounting hole 220, which can reduce the thickness of the electronic device.

Furthermore, other structures of this embodiment are the same as or similar to those of the above embodiments and will not be described in detail here.

The above descriptions are only some embodiments of the present application, and do not limit the protection scope of the present application.
