Description

Technical Field

[0001] The present application relates to the technical field of interactive mobile terminals, and in particular to a learning tablet. Background Art

[0002] Existing learning tablets are usually equipped with cameras to facilitate users to take photos of questions and upload them. To facilitate user operation, some tablets will have a reflector above the front camera. The reflector is tilted to face the desktop and the front camera. The question book on the desktop is mapped into the reflector. The picture mapped in the reflector taken by the front camera is the virtual image of the learning material. Therefore, the tablet can be kept upright on the desktop and the picture can be taken with one click. Although this method can facilitate users to quickly take photos of questions without moving the learning tablet, it has derived another problem: many existing software or website login accounts usually require face verification, and face recognition unlocking the screen is also a more convenient unlocking method than password unlocking. The reflector set above the front camera will block the camera. When face recognition or portrait shooting is required, the reflector needs to be removed first, and then the reflector is reinstalled after the shooting is completed. At this time, the presence of the reflector increases the user's operation steps, which brings inconvenience to the user. Utility Model Content

[0028] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0029] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0030] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0031] Existing learning tablets are usually equipped with cameras to facilitate users to take photos of questions and upload them. To facilitate user operation, some tablets will have a reflector above the front camera. The reflector is tilted to face the desktop and the front camera. The question book on the desktop is mapped into the reflector. The picture mapped in the reflector taken by the front camera is the virtual image of the learning material. Therefore, the tablet can be kept upright on the desktop and the picture can be taken with one click. Although this method can facilitate users to quickly take photos of questions without moving the learning tablet, it has derived another problem: many existing software or website login accounts usually require face verification, and face recognition unlocking the screen is also a more convenient unlocking method than password unlocking. The reflector set above the front camera will block the camera. When face recognition or portrait shooting is required, the reflector needs to be removed first, and then the reflector is reinstalled after the shooting is completed. At this time, the presence of the reflector increases the user's operation steps, which brings inconvenience to the user.

[0032] like Figure 1 As shown, this embodiment provides a learning tablet, including:

[0033] The tablet host 1 includes a first front camera 11 and a second front camera 12; the first camera 11 and the second camera 12 are both front-mounted and can shoot scenes in front of the tablet host 1;

[0034] The reflective mirror 2 is mounted on the tablet host 1 and extends relative to the display surface of the tablet host 1 . The field of view of the first camera 11 falls on the mirror surface of the reflective mirror 2 ; the field of view of the second camera 12 avoids being blocked by the reflective mirror 2 .

[0035] Among them, the field of view of the first camera 11 and the second camera 12 refers to the scene that can be captured by the camera. The field of view of the first camera 11 falls on the mirror surface of the reflector 2, indicating that the first camera 11 captures the scene inside the reflector 2; the field of view of the second camera 12 avoids the reflector 2, indicating that the second camera 12 will not capture the reflector 2.

[0036] Reference Figure 1 When the learning tablet is in normal use, it is generally supported by the bottom bracket and tilted upright on the desktop. Based on this state, the reflector 2 is tilted and installed above the first camera 11. The learning materials on the desktop can be mapped to the reflector 2. Figure 3 The first field of view A captured by the first camera 11 just falls on the mirror surface of the reflector 2. Therefore, when it is necessary to take a picture of the question, the first camera 11 can be directly called, and the function of directly taking a picture of the question without moving the learning tablet can be realized.

[0037] In addition, the learning tablet of this solution is also provided with a second camera 12, such as Figure 3 As shown, the second field of view 8 captured by the second camera 12 can completely avoid being blocked by the reflector 2. Therefore, when face recognition or portrait shooting is required, the second camera 12 can be directly called, and the function of directly shooting the user's portrait can be realized without moving the learning tablet or removing the reflector 2.

[0038] Specifically, the installation position of the reflector 2 is determined by the setting position of the first camera 11. Therefore, in order to enable the second camera 12 to avoid being blocked by the reflector 2, it is only necessary to ensure that there is a sufficiently large distance between the first camera 11 and the second camera 12. The distance is specifically determined by the actual size of the reflector 2 and the size of the second field of view B of the second camera 12. During specific implementation, technical personnel in this field can determine the specific positions of the first camera 11 and the second camera 12 according to the specifications of the selected reflector 2 and the second camera 12.

[0039] In summary, based on the learning tablet of the present embodiment, a front first camera 11 and a second camera 12 are arranged on the tablet host 1, and a reflector 2 is installed above the first camera 11. The field of view captured by the first camera 11 falls on the mirror surface of the reflector 2, so that the function of shooting learning materials spread on the desktop can be realized; the field of view captured by the second camera 12 avoids the obstruction of the reflector 2, so that the second camera 12 can shoot the portrait of the user in front of the learning tablet. When face recognition or portrait shooting is required, the second camera 12 can be directly called, and the user does not need to disassemble and assemble the reflector 2, so the operation is simpler and the experience effect is better.

[0040] In one embodiment, referring to Figure 3 , the minimum distance between the edge of the field of view of the second camera 12 and the reflector 2 is greater than 0.5 mm.

[0041] In terms of design, the minimum distance between the second camera 12 and the reflector 2 is controlled to be above 0.5 mm, which can compensate for the processing error of the reflector 2 and the error in the installation position of the reflector 2 and the second camera 12, and avoid the problem that the corners of the reflector 2 after installation block the edge of the field of view captured by the second camera 12.

[0042] In one embodiment, the first camera 11 is disposed on the top of the tablet host 1 , and the reflective mirror 2 is disposed above the first camera 11 .

[0043] Specifically, the orientation description of this embodiment is based on the placement state of the tablet host 1 in normal use, that is, Figure 1 The state shown is a reference, and the first camera 11 is arranged on the top of the tablet host 1 , so that the first camera 11 can maintain a maximum distance from the desktop, so that the upper mirror 2 can map a larger range of the desktop image, that is, expand the shooting range of the first camera 11 .

[0044] In one embodiment, the second camera 12 and the first camera 11 are disposed at a distance from each other on the top of the tablet host 1 .

[0045] The second camera 12 is also disposed on the top of the tablet host 1 like the first camera 11, so that the second camera 12 can capture the portrait of the user in front more comprehensively. Moreover, the wiring connection of the first camera 11 and the second camera 12 inside the tablet host 1 can be facilitated.

[0046] In one embodiment, referring to Figure 6 The central axis of the second camera 12 is swung relative to the display surface toward the center direction of the tablet host 1, and the angle between the central axis of the second camera 12 and the display surface of the tablet host 1 is 85° to 88°.

[0047] Specifically, refer to Figure 1 In normal use, the tablet host 1 is tilted and the display surface is tilted upward, which will cause the second field of view B of the second camera 12 to tilt upward, and ultimately the portrait can only be located in the lower area of ​​the picture, affecting the comprehensiveness of the portrait. Figure 6 , the plane where the display surface of the tablet host 1 is located is C, the central axis of the second camera 12 is O, the angle between the line O and the plane C is ∠a, the line O is deflected toward the center direction of the tablet host 1 relative to the plane C, and the size of ∠a is 85°~88°, which is equivalent to deflecting the second field of view B captured by the second camera 12 downward by 2°~5°, which can just compensate for the upward inclination of the tablet host 1 to a certain extent, so that the second camera 12 can capture the portrait of the user in front more comprehensively.

[0048] In one embodiment, a camera bracket is provided in the tablet host 1, and the camera bracket has a mounting groove 1331, and the angle between the bottom surface of the mounting groove 1331 and the display surface is 2° to 5°; the second camera 12 is installed in the mounting groove 1331 and fits the bottom surface of the mounting groove 1331.

[0049] Specifically, a mounting groove 1331 is provided on the camera bracket for mounting the second camera 12, referring to Figure 6-7 , the angle between the bottom surface of the installation groove 1331 and the display surface is ∠b, and ∠b is controlled within 2° to 5°. During installation, as long as the back of the second camera 12 is completely in contact with the bottom surface of the installation groove 1331, the size of the aforementioned ∠a can be controlled within 85° to 88°. Therefore, this structure can facilitate the installation angle of the second camera 12 to be controlled within the required tilt range.

[0050] In one embodiment, the tablet host 1 includes a host back shell 13 , and the camera bracket and the host back shell 13 are an integrally formed structure.

[0051] Specifically, the camera bracket is integrally formed with the host back shell 13, which can reduce the number of structural parts of the tablet host 1, simplify the assembly process, and improve the reliability of the structure. In addition, the integrated structure can also avoid the problem that the assembly error of the camera bracket affects the inclination accuracy of the second camera 12 after installation.

[0052] In one embodiment, referring to Figure 4 The host back shell 13 includes an integrally formed frame 132, an inner support platform 133 and a back plate 131. The inner support platform 133 is arranged around the inner circumference of the frame 132, the back plate 131 is connected to the back side of the inner support platform 133, and the front side of the inner support platform 133 supports the screen cover 14; the camera bracket is formed on the inner support platform 133.

[0053] The inner support platform 133 formed on the inner periphery of the frame 132 can just support the periphery of the screen cover 14, providing reliable support for the screen cover 14. The camera bracket is formed on the inner support platform 133, and the second camera 12 can be placed on the back side of the screen cover 14, so that the display surface of the entire tablet host 1 is flat.

[0054] In one embodiment, a supporting rubber frame 15 suitable for cooperating with the periphery of the screen cover 14 is installed on the front side of the inner supporting platform 133 , and the inner supporting platform 133 supports the screen cover 14 through the supporting rubber frame 15 .

[0055] A supporting rubber frame 15 is provided between the inner supporting platform 133 and the screen cover 14. The host back shell 13 itself can be made of a material with a relatively high hardness to ensure the rigidity of the entire tablet host 1. The supporting rubber frame 15 is made of a material with a lower hardness than the host back shell 13, which can buffer the impact on the screen cover 14 and reduce the risk of the screen cover 14 falling and breaking. The supporting rubber frame 15 is preferably bonded to the host back shell 13 by gluing.

[0056] In one embodiment, a first magnetic block is disposed in the tablet host 1, the reflector 2 includes a mirror housing 21 and a lens 22 mounted on the mirror housing 21, a second magnetic block corresponding to the first magnetic block is disposed in the mirror housing 21, and the first magnetic block and the second magnetic block are magnetically attracted.

[0057] The reflector 2 is installed by magnetic attraction, which has the advantage of convenient assembly and disassembly, and is convenient for removing the reflector 2 when storing. In addition, the first magnetic block and the second magnetic block are built-in, and will not be exposed and affect the appearance of the tablet host 1.
