Detailed Implementation

[0041] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0042] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0043] Please refer to Figure 1 and Figure 2 , Figure 1 An exploded view of a flat panel electronic device 100 shown as an exemplary embodiment of this application. Figure 2 This is the front view of the external camera module 20 installed on the tablet body 10.

[0044] This application provides a tablet-type electronic device 100, which includes a tablet body 10 and an external camera module 20. The tablet body 10 includes, but is not limited to, a tablet computer, a tablet learning device, and a tablet game console. The tablet body 10 includes a frame 11, and the frame 11 has a notch 110. The external camera module 20 is installed in the notch 110, which allows at least a portion of the external camera module 20 to be housed within the notch 110, realizing a housed design of the external camera module 20 in the tablet body 10 and reducing the space occupied by the external camera module 20.

[0045] The notch 110 can be a through notch that extends along the thickness direction of the plate body 10, or a non-through notch that does not extend along the thickness direction of the plate body 10. This embodiment adopts the former. The through notch makes the appearance of the plate body 10 simple and facilitates processing and manufacturing.

[0046] It should be noted that the external camera module 20 can be installed on the top edge of the tablet body 10 when in use. In some other embodiments, the external camera module 20 can also be installed on the left or right side edges of the tablet body 10. The terms "top," "bottom," "left," and "right" in this document refer to the top, bottom, left, and right positions of the tablet body 10 when in use. Figure 2 Text tags in the text.

[0047] Please combine Figure 2 and Figure 3 , Figure 3 This is a partially enlarged view of the external camera module 20 installed on the tablet body 10, in which some parts such as the module shell of the external camera module 20 have been removed.

[0048] The external camera module 20 includes a first front-facing camera 23 and a second front-facing camera 24. The first front-facing camera 23 and the second front-facing camera 24 are used to capture images in front of the tablet body 10. The shooting direction of the first front-facing camera 23 is different from that of the second front-facing camera 24. Here, "shooting direction" refers to the direction of the camera's optical axis. This external camera module 20 can capture more images through the first front-facing camera 23 and the second front-facing camera 24.

[0049] This application does not limit the specific manner in which the notch 110 is formed on the frame 11. For example, the notch 110 may be formed by removing part of the material from the frame 11. In this embodiment, the frame 11 is recessed inward. Specifically, the tablet body 10 also includes a plate-shaped main body portion 12 surrounded by the frame 11. A recess 120 is formed on the main body portion 12 at the portion corresponding to the notch 110. The frame 11 is recessed inward at the recess 120 to form the notch 110. With this configuration, it is not necessary to remove material from the frame 11, thereby avoiding weakening the strength of the frame 11. Furthermore, providing a recess 120 on the main body portion 12 helps to increase the depth at the notch 110, allowing the external camera module 20 to be better accommodated within the notch 110, thus reducing the overall size of the device 100.

[0050] In one embodiment, the main body 12 includes a display area 12a on the front and a non-display area 12b located outside the display area 12a. The recess 120 is disposed in the non-display area 12b and extends through the thickness direction of the main body 12. This arrangement ensures that the recess 120 is only formed in the non-display area 12b, thus not affecting the display effect of the display area 12a. Furthermore, the through-type recess 120 facilitates compatibility with the external camera module 20.

[0051] In one embodiment, such as Figure 3 As shown, the first front-facing camera 23 is positioned so that its shooting direction faces the user in front of the tablet body 10. The second front-facing camera 24 is tilted downwards relative to the first front-facing camera 23, and its shooting direction faces the desktop in front of the user. The shooting direction of the first front-facing camera 23 is referenced to... Figure 3 The direction of the optical axis O1 of the first front-facing camera 23 is shown in the figure, and the shooting direction of the second front-facing camera 24 is referenced. Figure 3 The direction of the optical axis O2 of the second front-facing camera 24 is shown in the figure. For example, the first front-facing camera 23 can capture the user's image, including but not limited to the user's sitting posture and expression, and the second front-facing camera 24 can capture information about objects on the table in front of the user, including but not limited to test papers and books. Therefore, when using this device 100 to carry out teaching and other tasks, there can be more interaction with the user, and the teaching method is more convenient.

[0052] Please combine Figure 2 and Figure 4 , Figure 4 This is a partial magnified view of the left side of the flat panel electronic device 100.

[0053] The tablet body 10 also includes a display screen 13. The main body 12 is provided with the display screen 13. The side of the tablet body 10 with the display screen 13 is the front, which is the image display surface. The side of the tablet body 10 facing away from the display screen 13 is the back. The external camera module 20 includes a front portion 20a on the front and a rear portion 20b on the back. The lower edge 201 of the front portion 20a is lower than the notch 110. With this configuration, the front portion 20a can cover the notch 110, preventing the notch 110 from being exposed and improving the appearance.

[0054] In one embodiment, the front portion 20a and the upper end of the rear portion 20b are connected to form a bent structure in the shape of a "7". That is, the front portion 20a is formed as a horizontal part of the "7" shape, and the rear portion 20b is formed as a vertical part of the "7" shape. The structure is simpler and more compact, making it easier to mount or install the external camera module 20 on the edge of the tablet body 10.

[0055] In one embodiment, the front portion 20a is attached to the front of the tablet body 10, the rear portion 20b is attached to the back of the tablet body 10, and the junction of the front portion 20a and the rear portion 20b is attached to the frame 11. This facilitates the stability of the external camera module 20 installation, and the external camera module 20 occupies relatively little external space on both the front and back of the tablet body 10, making the overall structure of the tablet electronic device 100 more compact.

[0056] Please refer to Figures 5 to 8 , Figure 5 This is a partial enlarged view of a portion of the structure of a flat panel electronic device 100. Figure 6 yes Figure 5 AA view in the middle. Figure 7 yes Figure 5 BB view in the middle. Figure 8 This is a schematic diagram of the shooting field of view of the second front-facing camera 24.

[0057] In one embodiment, such as Figure 6 As shown, the angle γ between the optical axis O1 of the first front-facing camera 23 and the display screen 13 is 80° to 110°, such as 80°, 82°, 85°, 90°, 92°, 95°, 100°, 102°, 105°, 108°, and 110°, but not limited to these. This is based on the consideration that the tablet electronic device 100 is usually positioned in front of the user during use, but the tablet electronic device 100 may have a certain tilt angle. By setting the shooting direction of the first front-facing camera 23 to an angle of 80° to 110° with the display surface, the first front-facing camera 23 can better capture the user's posture, and the shooting direction of the first front-facing camera 23 can be perpendicular to or nearly perpendicular to the user, thus ensuring the accuracy of the acquisition. It is understandable that when the angle between the shooting direction of the first front camera 23 and the display surface is greater than 90°, the shooting direction of the first front camera 23 will be slightly tilted away from the display surface. This design can compensate for the angle deviation caused by the placement of the tablet electronic device 100 and improve the acquisition accuracy.

[0058] In one embodiment, such as Figure 7 As shown, the angle α between the optical axis O2 of the second front-facing camera 24 and the display screen 13 is 50° to 75°. For example, it can be 50°, 55°, 60°, 65°, 70°, or 75°. Figure 8As shown, when the tablet body 10 is upright and displays image information through the display surface, it is convenient for the second front camera 24 to take pictures from above. By selecting an tilt angle of 50° to 75° and combining it with the control of the focal length of the second front camera 24, it is convenient to collect image information of an area of ​​approximately 240 (width) * 340 (height) mm in front of the user through the second front camera 24. For example, it is convenient to realize the linkage between teaching and test papers or paper, making teaching more convenient.

[0059] exist Figure 7 In the illustrated embodiment, the external camera module 20 further includes a front cover plate 25 disposed in front of the first front-facing camera 23 and the second front-facing camera 24. The front cover plate 25 is made of a light-transmitting material, and includes, but is not limited to, a light-transmitting glass cover. In one embodiment, the front cover plate 25 can be a dark-colored transparent glass cover, which allows light to pass through while preventing the first front-facing camera 23 and the second front-facing camera 24 from being exposed, thus protecting and sealing the first front-facing camera 23 and the second front-facing camera 24.

[0060] It should be noted that the front cover 25 is a one-piece cover used to shield both the first front-facing camera 23 and the second front-facing camera 24. That is, the same front cover 25 can simultaneously shield both the first front-facing camera 23 and the second front-facing camera 24. Compared to the prior art where multiple cameras are shielded by multiple covers, this reduces the number of structural components, simplifies the assembly process, and results in a more compact structural layout. In this embodiment, the front cover 25 is configured as an oblong cover with semi-circular ends and a rectangular middle section (see...). Figure 2 The first front-facing camera 23 and the second front-facing camera 24 are arranged side by side at both ends of the length direction of the front cover plate 25.

[0061] In one embodiment, the front cover plate 25 is tilted downwards, and the tilt direction of the front cover plate 25 is the same as that of the second front-facing camera 24. The upper end of the front cover plate 25 is not lower than the upper edge of the first front-facing camera 23, and the lower end of the front cover plate 25 is not higher than the lower edge of the second front-facing camera 24. That is, the front cover plate 25 is also configured to tilt towards the second front-facing camera 24, and its lower end is not higher than the lower edge of the second front-facing camera 24. This avoids the front cover plate 25 obstructing the field of view of the second front-facing camera 24. Simultaneously, the upper end of the front cover plate 25 is not lower than the upper edge of the first front-facing camera 23, thus ensuring that the front cover plate 25 does not obstruct the field of view of the first front-facing camera 23.

[0062] With the vertical plane as a reference plane, the angle β of the front cover plate 25 tilting downward relative to the vertical plane is 20° to 40°, for example, it can be 20°, 22°, 25°, 30°, 33°, 35°, 38°, or 40°. With this configuration, the front cover plate 25 forms a certain tilt angle with the display surface of the tablet body 10, making it easier to tilt the second front-facing camera 24 relative to the display surface of the tablet body 10. This helps to reduce the overall thickness of the external camera module 20 and minimize the thickness difference between the camera module 20 and the tablet body 10.

[0063] Please refer to Figure 9 , Figure 9 This is a schematic diagram of the module housing 21.

[0064] In one embodiment, the external camera module 20 further includes a module housing 21, within which the first front-facing camera 23 and the second front-facing camera 24 are housed. The module housing 21 has a front viewing window 210, and a front cover plate 25 covers the front viewing window 210 (see...). Figure 5 The module housing 21 includes a rigid frame 21a and a decorative element 21b covering the frame 21a, the decorative element 21b forming the exterior appearance of the module housing 21. This configuration increases the strength of the module housing 21, thereby increasing the impact resistance of the external camera module 20 when dropped. The frame 21a may include, but is not limited to, a magnesium alloy frame or an aluminum alloy frame. The bracket 22 is connected to the frame 21a, providing a stronger connection.

[0065] In an alternative embodiment, the skeleton 21a and the decorative element 21b are configured as an integral structure. For example, the decorative element 21b is made of plastic, and the skeleton 21a can be integrally injection molded with the decorative element 21b as an insert, but it is not limited to this.

[0066] Please refer to Figure 10 , Figure 10 This is a schematic diagram of part of the structure of the external camera module 20.

[0067] In one embodiment, the external camera module 20 further includes a display panel 29 housed within the module housing 21 and a touch switch (not shown) electrically connected to the display panel 29. The display panel 29 faces the front cover 25 and can transmit light through the front cover 25 to display images. The touch switch has a touch surface for human touch, which is exposed on the outside of the module housing 21. The touch surface is used to turn the display panel 29 on or off. The display panel 29 may include, but is not limited to, an LED panel. In this embodiment, the display panel 29 serves as an auxiliary display screen, through which auxiliary information such as time, date, temperature, and light intensity can be displayed. The auxiliary display screen can also display prompts to the user, such as prompting the user to take a proper rest or correct their posture. The combination of the auxiliary display screen and the display screen 13 of the tablet body 10 enriches the functionality of the tablet electronic device 100. As an auxiliary display screen, the display panel 29 can be turned on by the touch switch according to user needs, thus reducing energy consumption and extending battery life. It should be noted that the touch surface of the touch switch can be coplanar with the outer surface of the module housing 21, thereby improving the appearance of the module housing 21.

[0068] In one embodiment, the external camera module 20 further includes a bracket 22 housed within the module housing 21. The bracket 22 is connected to the frame 21a. The first front camera 23, the second front camera 24, and the display panel 29 are all mounted on the bracket 22, thus achieving the integration of the first front camera 23, the second front camera 24, the display panel 29, and the bracket 22, resulting in a higher degree of modularity.

[0069] In one embodiment, a display panel 29 is disposed between the first front-facing camera 23 and the second front-facing camera 24, with the display panel 29, the first front-facing camera 23, and the second front-facing camera 24 arranged side by side. Figure 10 In the illustrated embodiment, a gap is left between the first front-facing camera 23 and the second front-facing camera 24, and the display panel 29 is disposed within this gap. This arrangement allows the display panel 29 to effectively utilize space and avoid waste. It should be noted that, to prevent the shooting fields of the first front-facing camera 23 and the second front-facing camera 24 from overlapping, the first front-facing camera 23 and the second front-facing camera 24 should be separated by a preset distance, thus forming a gap between them. The placement of the display panel 29 effectively utilizes this gap, avoiding wasted space. Furthermore, the display panel 29 is located on the rear side of the front cover 25, preventing the user from directly touching it to open or close it. Instead, it is opened or closed via a touch switch. This allows for protection of the display panel 29 by the front cover 25 and also enables the use of a lower-cost LED panel, reducing costs.

[0070] Please refer to Figure 11 , Figure 11 This is another exploded view of the external camera module 20.

[0071] In one embodiment, the module housing 21 is further provided with a rear view window 214, and the external camera module 20 also includes a rear camera 27 housed within the module housing 21, the rear camera 27 capturing images through the rear view window 214. With this configuration, the external camera module 20 also integrates a rear camera, resulting in enhanced shooting capabilities.

[0072] exist Figure 11 In the illustrated embodiment, the external camera module 20 further includes a rear cover plate 28 covering the rear viewing window 214. The rear camera 27 can capture images through the light-transmitting area 280 of the rear cover plate 28. The light-transmitting area can be configured as a light-transmitting hole or made of a light-transmitting material. The external camera module 20 can also be equipped with a fill light, which can provide illumination for the rear camera. Correspondingly, a light-transmitting area can be provided on the rear cover plate 28 facing the fill light. The light-transmitting area includes, but is not limited to, a fill light hole or a light-transmitting material.

[0073] In one embodiment, the field of view of at least one of the first front-facing camera 23 and the second front-facing camera 24 is adjustable. For example, the first front-facing camera 23 can be dynamically adjusted, such as tilting up or down. The second front-facing camera 24 can also be dynamically adjusted, such as tilting up or down. Both the first front-facing camera 23 and the second front-facing camera 24 can be manually or automatically adjusted.

[0074] In one embodiment, the external camera module 20 is movably mounted on the tablet body 10, and the movement includes, but is not limited to, linear movement or fixed-axis rotation, which allows the shooting field of view of the external camera module 20 to be adjusted. In this embodiment, the external camera module 20 is detachably mounted on the frame 11 of the tablet body 10, and remains relatively fixed to the tablet body 10 after installation. The installation method includes, but is not limited to, snap-fit ​​or bolt connection, which helps to achieve the stability of the installation of the external camera module 20 and facilitates replacement and maintenance. The external camera module 20 is connected to the tablet body 10 through a frame 21a.

[0075] Please refer to Figure 12 , Figure 12 This is a top view of a flat panel electronic device 100.

[0076] In one embodiment, the ratio of the thickness dimension t1 of the tablet body 10 to the dimension t2 of the external camera module 20 in this direction is 0.35 to 0.45, for example, it can be 0.35, 0.4, or 0.45, but is not limited to these. The "thickness dimension" referred to here means the dimension from the front side of the tablet body 10 to the back side of the tablet body 10, i.e., the front-to-back direction (see...). Figure 11 The size of the text markers in the text.

[0077] In one alternative embodiment, the thickness t1 of the tablet body 10 is 7.25 mm, and the thickness t2 of the external camera module 20 is 18.2 mm, with a t1:t2 ratio of 0.4, thus achieving a thinner and lighter design for the external camera module 20.

[0078] In one embodiment, such as Figure 2 As shown, the tablet body 10 is also equipped with a distance sensor 15 and / or an ambient light sensor 14. The distance sensor 15 can obtain the distance between the user and the tablet body 10, and can determine the user's posture by combining the information collected by the external camera module 20, so as to remind the user to correct their sitting posture. The ambient light sensor 14 can collect the ambient light information of the space where the user is located, so as to remind the user to adjust the brightness of the light. In this technical solution, the distance sensor 15 and / or the ambient light sensor 14 are set inside the tablet body 10, so as not to affect the modular assembly of the components inside the external camera module 20, and to minimize the change in the original structure of the tablet electronic device 100, which is conducive to reducing the size of the external camera module 20.

[0079] In some other embodiments, the distance sensor 15 and / or the ambient light sensor 14 may also be disposed within the external camera module 20, thereby making full use of the internal space of the external camera module 20.

[0080] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
