Detailed Implementation

[0038] 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.

[0039] 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.

[0040] refer to Figures 1-3 This application provides an electronic device. The electronic device includes a mobile terminal device 200 and a projectable base 100. The projectable base 100 includes a housing 1, a magnetic component 2, and a projection module 3. The housing 1 includes a mounting portion 11 and a viewing window portion 12. The viewing window portion 12 includes an opening 121. When the projectable base 100 is placed on a projection surface PS, the viewing window portion 12 is closer to the projection surface PS than the mounting portion 11. The magnetic component 2 is disposed inside the housing 1 and is used to detachably attach the mobile terminal device 200 to the mounting portion 11. The projection module 3 is disposed in the viewing window portion 12 and faces the opening 121. The projection module 3 is used to signal connect with the mobile terminal device 200 and project an image onto the projection surface PS. When the mobile terminal device 200 is connected to the mounting portion 11, the mobile terminal device 200 does not obstruct the projection path of the projection module 3.

[0041] The mobile terminal device 200 of this application can be a tablet computer, smartphone, e-reader, etc. The viewing window 12 is closer to the projection surface PS than the mounting part 11, and the projection module 3 can project images onto the projection surface PS. This means that the light emission direction of the projection module 3 is towards the projection surface PS, and not towards the connection point of the mobile terminal device 200. When a user uses an electronic device, their eyes are usually directly focused on the direction of the mobile terminal device 200. Therefore, this arrangement avoids the light emitted from the projection module 3 directly entering the user's eyes and causing vision damage. Furthermore, the light emitted by the projection module 3 undergoes diffuse reflection through the projection surface PS before entering the user's eyes, reducing eye strain, weakening blue light reflection, and making the image display softer.

[0042] This design allows the electronic device to protect the user's eyesight to some extent, preventing eye strain from prolonged study. Furthermore, since the mounting part 11 is located on the side of the viewing window 12 furthest from the projection surface PS, the projection base 100 can function as a stand to raise the height of the mobile terminal device 200, making it more comfortable for the user to view the screen of the mobile terminal device 200 while seated at a table, without needing to adjust their head angle. In addition, the electronic device projects images onto the projection surface PS. Users can interact with the images through the projection surface PS, which enhances the enjoyment of learning and increases the user's interest in learning.

[0043] When the mobile terminal device 200 is connected to the mounting unit 11, the mobile terminal device 200 does not obstruct the projection path of the projection module 3. This can be achieved by aligning the mobile terminal device 200 with the edge of the mounting unit 11 near the viewing window 12, thereby maximizing the exposure of the viewing window 12 and preventing the mobile terminal device 200 from obstructing the emitted light from the projection module 3. Alternatively, as... Figure 3 As shown, the edge of the mobile terminal device 200 near the projection surface PS protrudes from the mounting portion 11, but still does not obstruct the emitted light from the projection module 3. This arrangement allows the mobile terminal device 200 to reduce the likelihood of the user's eyes observing the viewing window portion 12 to a certain extent.

[0044] The projection stand 100 can project the same image as the display screen of the mobile terminal device 200, allowing users to choose a learning mode according to their needs. Alternatively, the projection stand 100 can project images with different content than the display screen of the mobile terminal device 200. For example, the display screen of the mobile terminal device 200 could display a teacher's lecture video, while the projection module 3 could project images of test questions. This setup allows the image projected by the projection module 3 to act as an extended screen for the mobile terminal device 200, enabling children to receive more information simultaneously and meeting different learning needs.

[0045] The magnetic connection between the magnetic component 2 and the mobile terminal device 200 can be achieved through a connection using an external magnetic component within the mobile terminal device 200. In this case, after the mobile terminal device 200 and the magnetic component 2 are connected, the relative positional relationship between the mobile terminal device 200 and the mounting portion 11 is fixed. Alternatively, in embodiments where the housing of the mobile terminal device 200 includes a metal portion, the magnetic component 2 can be directly attracted to the metal portion to achieve a connection. This arrangement reduces the number of internal components of the mobile terminal device 200 and allows the user to easily adjust the position of the mobile terminal device 200 as needed. Furthermore, multiple magnetic components 2 can be included, allowing for multiple matching connections with the mobile terminal device 200 within the mounting portion 11, thereby improving the stability of the connection.

[0046] Optionally, the housing 1 also includes a base portion 13, with a viewing window portion 12 disposed between the mounting portion 11 and the base portion 13. For example... Figure 3 As shown, the angle α between the base portion 13 and the opening 121 in the window portion 12 is an obtuse angle. Setting the angle α to an obtuse angle increases the space between the window portion 12 and the base portion 13, allowing the light emitted by the projection module 3 to move further away from and closer to the projectable base 100. When the mobile terminal device 200 is assembled on the mounting portion 11 and the user is facing the mobile terminal device 200, this arrangement allows the projectable base 100 to project an image with a higher screen height from the user's perspective, such as... Figure 5 As shown, with the increased image height, the projection base 100 can project more image content, or project images onto a larger screen to reduce reading difficulties for the user.

[0047] Combination Figure 2 In some optional embodiments, the base portion 13 includes a central region 131 and an edge region 132. The edge region 132 and the central region 131 are arranged along the width direction, and the central region 131 is located within the edge region 132. The width direction should be understood as the left-right direction of the projection of the base 100 from the user's perspective when the mobile terminal device 200 is assembled on the mounting portion 11 and the user is facing the mobile terminal device 200. The central region 131 may be centrally located within the edge region 132, or it may be offset from the center. In this embodiment, the opening 121 is provided facing the central region 131. The angle α between the central region 131 and the viewing window portion 12 is an obtuse angle. The edge region 132 is connected to the mounting portion 11 and is located on the same plane.

[0048] In other words, in this embodiment, the mounting portion 11 and the edge region 132 of the projectable base 100 have a smooth transition, while the central region 131 and the viewing window 12 are recessed into the planar mounting portion 11 and the edge region 132. When the user moves the projectable base 100, their hand tends to grip the base portion 13, at which point the user's thumb tends to be placed on the edge region 132 and extends towards the mounting portion 11. Thus, the edge region 132 and the mounting portion 11 being on the same plane improves the user's grip comfort and provides more force and gripping area for children with smaller hands, facilitating user movement.

[0049] exist Figures 1-3 In the illustrated embodiment, the opening 121 on the window portion 12 is a plane. The side of the base portion 13 facing the opening 121 is also a plane. Therefore, the included angle α is easily understood as the angle between the planar window portion 12 and the planar base portion 13. Figure 4In the illustrated embodiment, the opening 121 of the window portion 12 is an arc surface, and the base portion 13 is also a cylindrical design. Therefore, the included angle α should be understood as the included angle between the cross-section of the window portion 12 and the cross-section of the base portion 13.

[0050] Combination Figure 3 and Figure 4 In some optional embodiments, on the light-emitting side of the projection module 3, the included angle β between the base portion 13 and the projection surface PS is greater than or equal to 90°. When the included angle β is 90°, the base portion 13... Figure 4 The base portion 13 is perpendicular to the projection surface PS. This arrangement allows the base portion 13 to be as far away as possible from the light emitted by the projection module 3, preventing the projected image from being projected onto the base portion 13 and thus affecting the projection effect.

[0051] When the included angle β is greater than 90°, such as 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, etc., since the included angle α between the base portion 13 and the opening 121 of the window portion 12 is also an obtuse angle, the obtuse angle β can further oriented the opening 121 of the window portion 12 towards the user. With this setting, the light emitted by the projection module 3 can be projected onto a farther position on the projection surface PS, thereby enabling the projection module 3 to project a higher image.

[0052] like Figure 3 As shown, in some optional embodiments, the angle θ between the mounting portion 11 and the viewing window portion 12 is obtuse in the direction away from the light-emitting side of the housing 1 from the projection module 3. The projection module 3, disposed in the opening 121 of the viewing window portion 12, can project an image onto the projection surface PS, meaning that the opening 121 faces the projection surface PS. Since the angle θ between the mounting portion 11 and the viewing window portion 12 is obtuse, it means that when the user is seated on the light-emitting side of the projection base 100, the mounting portion 11 tilts backward. Thus, when the mobile terminal device 200 is attached to the mounting portion 11, the display screen of the mobile terminal device 200 tilts towards the side away from the projection surface PS, allowing the user to view the display screen by slightly lowering their head.

[0053] Furthermore, in embodiments where the mobile terminal device 200 includes a camera module, the setting of the included angle θ enables the camera module to better collect information such as the user's sitting posture, thereby better determining whether the user's posture is correct or more easily unlocking the mobile terminal device 200.

[0054] The included angle θ is set such that an included angle γ is formed between the surface of the mounting part 11 connected to the mobile terminal device 200 and the vertical plane VP. In some optional embodiments, the included angle γ between the mounting part 11 and the vertical plane VP is greater than or equal to 15° and less than or equal to 30°. For example, the included angle γ can be any value between 15°, 17°, 19°, 21°, 23°, 25°, 27°, 29°, and 30°. An included angle γ within this range ensures that the angle at which the mobile terminal device 200 faces the user after being attached to the mounting part 11, thereby facilitating better viewing of the display screen of the mobile terminal device 200 from a seated position and avoiding eye fatigue caused by excessive angular differences between the user's line of sight and the display screen.

[0055] refer to Figure 3 The housing 1 includes a top surface 14 disposed away from the projection surface PS. In some embodiments, the height distance between the top surface 14 and the projection surface PS gradually decreases in the direction from the light-emitting side of the projection module 3 to the side away from the light-emitting side. Figure 3 From the shown perspective, the light-emitting side of the projection module 3 is located on the left. Therefore, in this perspective, this embodiment should be understood as having a gradually decreasing distance between the top surface 14 and the projection surface PS from left to right. Because the mounting portion 11 is tilted, the top surface 14 tilts in accordance with the tilt direction of the mounting portion 11. Compared to the embodiment where the top surface 14 is parallel to the projection surface PS, the angle between the top surface 14 and the mounting portion 11 is smaller in this embodiment. When the mobile terminal device 200 is attached to the mounting portion 11, the weight of the mobile terminal device 200 can be decomposed into a force parallel to the mounting portion 11 and a force perpendicular to the mounting portion 11. The smaller angle between the top surface 14 and the mounting portion 11 results in a smaller angle between the top surface 14 and the force perpendicular to the mounting portion 11, thereby better supporting the mobile terminal device 200 and improving the stability of the mobile terminal device 200.

[0056] The projection module 3 includes a light-emitting surface 31 positioned near the opening 121. For example... Figure 3 As shown, in some optional embodiments, the height distance H between the light-emitting point of the projection module 3 on the light-emitting surface 31 and the projection surface PS is greater than or equal to 15cm and less than or equal to 35cm. For example, the height distance H can be any value between 15cm, 16cm, 17cm, 18cm, 19cm, 20cm, 21cm, 22cm, 23cm, 24cm, 25cm, 26cm, 27cm, 28cm, 29cm, 30cm, 31cm, 32cm, 33cm, 34cm, and 35cm. When the area of ​​the light-emitting point of the projection module 3 is large, this height distance H should be understood as the height distance between the center point of the light-emitting point and the projection surface PS.

[0057] Since the projector base 100 is used for desktop projection, not long-distance projection, an excessively high height distance H would result in an excessively large dimension of the projector base 100 in the height direction. Conversely, an excessively small height distance H would make it difficult for the projection module 3 to project an image of suitable size and clarity onto the projection surface PS. This height distance H is suitable for desktop projection and allows for adjustment of image parameters by adjusting the focal length of the projection module 3, making the image size suitable for children's learning scenarios.

[0058] In an optional embodiment, the projection module 3 is an ultra-short-throw projection module, that is, a projection ratio greater than or equal to 0.2:1 and less than or equal to 0.5:1. The ultra-short-throw projection module can project a large-screen image onto the projection surface PS at a short distance, and can provide clear images with high color fidelity and high contrast. The ultra-short-throw projection module effectively controls the height distance H, avoiding excessive dimensions of the projection base 100 in the height direction, which is beneficial for miniaturizing the projection base 100. Furthermore, for child users, high-color-saturation images can provide richer visual stimulation, thereby increasing the fun and interest children experience when learning.

[0059] Combination Figure 1 In some optional embodiments, the projector base 100 also includes a distance sensor 8 electrically connected to the projection module 3. The distance sensor 8 is housed within the housing 1 with its sensing end facing the opening 121. The distance sensor 8 is used to sense the distance between the user's head and the sensing end. When the distance sensed by the distance sensor 8 is less than or equal to a threshold, the projection module 3 stops projecting. When the user's head is too close to the sensing end of the distance sensor 8, it means that the user's eyes may be looking directly at the projection module 3, at which point the projection module 3 stops projecting. This configuration can prevent the light emitted by the projection module 3 from directly entering the user's eyes and causing vision damage. When the user is a child, children are more curious and therefore more likely to look at the projection module 3 to observe it. This configuration can better protect children and increase parents' peace of mind when using the projector base 100.

[0060] Optionally, the projection base 100 also includes an electrically connected camera module 6 and a camera signal terminal 7. The camera module 6 is housed within the housing 1, with its light-receiving side facing the opening 121. The camera signal terminal 7 is disposed on the mounting portion 11 and is used for signal connection with the mobile terminal device 200. The camera module 6 is used to capture images on the projection surface PS. The camera signal terminal 7 transmits the images captured by the camera module 6 to the mobile terminal device 200.

[0061] Combination Figure 5In this embodiment, the image projected by the projection module 3 onto the projection surface PS is the test question. The shooting module 6 can then be used to capture the answer selected by the user on the projection surface PS. After receiving the image captured by the shooting module 6, the shooting signal terminal 7 sends the image to the mobile terminal device 200. At this time, the mobile terminal device 200 can determine whether the user's answer is correct based on the image. Alternatively, the mobile terminal device 200 can send the answer to a remote teacher for the teacher to determine whether the answer is correct. Of course, the application scenarios of this embodiment are not limited to this. The shooting module 6 can also be used to capture the user's body movements, etc., thereby meeting more diverse teaching needs.

[0062] It is evident that the inclusion of the shooting module 6 and the shooting signal terminal 7 enhances the user's interactive experience with the projector base 100, thereby increasing the enjoyment of learning using the projector base 100 and further boosting user interest. Furthermore, this setup allows for real-time interaction with remote personnel, improving the flexibility of teaching in terms of personnel and space requirements.

[0063] Since the mobile terminal device 200 is in a working state when connected to the projectable base 100, there is a need for charging. In some optional embodiments, the projectable base 100 includes a base coil 5 disposed on the mounting portion 11. The mobile terminal device 200 includes a flat coil. When the mobile terminal device 200 is attached to the mounting portion 11, the base coil 5 cooperates with the flat coil to charge the mobile terminal device 200. The cooperation between the base coil 5 and the flat coil can be electromagnetic induction charging or magnetic resonance charging. This configuration allows the projectable base 100 to function as a wireless charging device for charging the mobile terminal device 200. Thus, when a user uses the projectable base 100, the user does not need to attach an additional power cord to the mobile terminal device 200 to maintain and provide power, which helps to improve the battery life of the mobile terminal device 200 while ensuring study time. When the user is a child, this configuration can prevent children from touching the power cord and causing danger.

[0064] The projector base 100 may require a power adapter and power cord to be connected to a socket for power supply. Alternatively, the projector base 100 may include a housing compartment for accommodating a commercially available battery to power its internal components. In some alternative embodiments, the projector base 100 may also include a battery 4 disposed within a housing 1. The housing 1 includes a power charging / discharging port electrically connected to the battery 4. The power charging / discharging port is located on the side of the housing 1 away from the opening 121. The battery 4 provides the projector base 100 with a certain energy storage capacity. This configuration allows the projector base 100 to be used in wireless scenarios. Users can still use the projector base 100 for learning even when outdoors or in situations without a suitable socket. Therefore, this embodiment reduces the scenario requirements for users using the projector base 100. The fact that the power charging / discharging port is located on the side of the housing 1 away from the opening 121 should be understood as the power charging / discharging port being located on the back of the projector base 100. The power charging / discharging port on the back allows the power cord to be positioned as far away from the opening 121 as possible, thereby preventing the image projected by the projection module 3 from being located on the power cord and thus affecting the projection effect.

[0065] When the mobile terminal device 200 is attached to the mounting unit 11, the electronic device may require the user to operate either the mobile terminal device 200 or the projector base 100 before the projection module 3 can be activated. Alternatively, in some optional embodiments, the projector base 100 includes a projection signal terminal 9 disposed on the mounting unit 11. The projection signal terminal 9 is electrically connected to the projection module 3 to send an operating signal to the projection module 3, thereby enabling the projection module 3. When the mobile terminal device 200 is connected to the mounting unit 11, the projection signal terminal 9 is electrically connected to the mobile terminal device 200 and directly sends an operating signal. In this embodiment, when the mobile terminal device 200 is connected to the mounting unit 11, the projection module 3 immediately projects an image onto the projection surface. This configuration makes the electronic device suitable for younger users without requiring constant parental supervision. Users only need to attach the mobile terminal device 200 to the mounting unit 11 to activate the projection of the projector base 100, which helps reduce the operational difficulty of the projector base 100 and avoids user frustration and confusion that could affect their learning interest.

[0066] The projection signal terminal 9 may protrude from the surface of the mounting portion 11 and be able to move inward toward the inside of the housing 1 under force. When the mobile terminal device 200 is connected to the mounting portion 11, the mobile terminal device 200 is attached to the surface of the mounting portion 11, thereby pressing the projection signal terminal 9 inward toward the inside of the housing 1. At this time, the projection signal terminal 9 can be energized and send a working signal to control the operation of the projection module 3. In other embodiments, the projection signal terminal 9 may be disposed inside the housing 1 and electrically connected to the mobile terminal device 200 via a Hall effect sensor, electromagnetic coil, or other means. Similarly, the shooting signal terminal 7 may also protrude from the surface of the mounting portion 11 or be disposed inside the housing 1. Further details on this aspect are omitted here.

[0067] Furthermore, this application does not limit the number and arrangement of the projection signal terminal 9 and the shooting signal terminal 7. Figure 1 The arrangement and quantity of the embodiments shown should be taken as exemplary and not as limiting. More projection signal terminals 9 and imaging signal terminals 7 may be included respectively, thereby reducing the possibility of false triggering.

[0068] Optionally, such as Figure 4 As shown, the housing 1 also includes heat dissipation holes 15. The heat dissipation holes 15 are located on the side of the housing 1 away from the opening 121. Components such as the projection module 3 may generate heat in real time during operation. The heat dissipation holes 15 allow heat inside the housing 1 to be dissipated to the outside in a timely manner, thereby preventing heat accumulation in the projection base 100 from damaging internal components and causing injury to the user. Furthermore, the heat from the projection base 100 can be conducted to the mobile terminal device 200 through the mounting part 11, thus timely heat dissipation also protects the mobile terminal device.

[0069] exist Figure 3 and Figure 4 In the illustrated embodiment, opening 121 is open. However, this should be taken as an example and not as a limitation. Opening 121 can be used to assemble structures such as glass sheets and resin sheets, thereby closing opening 121 to prevent external impurities from entering the interior of the housing 1 through opening 121 and damaging the internal components.

[0070] 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.
