[0042] The electronic device can be a tablet computer, which can be an educational tablet. The educational tablet is a smart learning device integrating multiple functions, widely used in school and home learning scenarios. The educational tablet can have the following functions: high-definition display and eye protection: reduce blue light through technology to protect students' vision; smart interaction: support electronic whiteboard, multi-touch, stylus input, etc., facilitating interaction between students and teachers; educational resources and applications: built-in rich educational applications and e-book library, supporting online learning; personalized learning: providing customized learning content based on students' learning progress and preferences through artificial intelligence technology; multi-screen collaboration and projection: supporting collaboration with other devices for easy resource sharing, etc.

[0043] The electronic device can be sold and used with a charging pen. The charging pen usually refers to a pen that supports electromagnetic induction or active capacitance. Compared with ordinary tablets, the electronic device with a charging pen has many unique advantages, especially for learning and creation scenarios. It can have a more natural writing experience, which can approach real paper and pen: the charging pen usually supports multi-level pressure sensing, which can adjust the line thickness according to the pressure change of the pen tip, simulating the writing and drawing effect of real paper and pen. And lower latency: high-quality charging pen and tablet can achieve low-latency writing, with almost synchronous pen tip movement and screen display, reducing the feeling of lag, making writing and drawing more smooth and natural, more suitable for educational tablets, which can effectively improve the user experience.

[0044] The charging pen can be charged wirelessly, making it convenient to charge. The charging pen can support wireless charging or magnetic charging, and can be charged by attaching it to the edge of the electronic device or a dedicated charging area, which is convenient to use.

[0045] Corresponding magnetic components can be provided in the electronic device and the charging pen.

[0046] In the prior art, when installing the charging transmitting coil, the top of the shell has been sealed, and the charging transmitting coil needs to be inserted from the bottom of the shell, sent into the inside of the shell, and then installed on the side plate. To this end, a through hole is formed in the bottom plate of the shell, and the charging transmitting coil needs to be moved from the through hole to the inside of the shell during installation. The installer needs to use a special tool or hand to move the charging transmitting coil from the through hole to the inside of the shell, and then install the charging transmitting coil on the side plate of the shell. This results in a larger through area of the through hole, which affects the strength of the shell, causing the strength of the shell to decrease, and deformation, cracking, etc. to occur during transportation and use, affecting the quality of the electronic device and the user experience.

[0047] In the prior art, a coil support is usually arranged, when installing the charging transmission coil, the charging transmission coil is first embedded into the coil support, so that the charging transmission coil is effectively fixed, then the charging transmission coil and the coil support enter the inside of the shell through the hole, and then the coil support is fixed to the side plate of the shell, so that the coil support can provide sufficient fixed fulcrum between the charging transmission coil and the side plate, whether it is point fixing or clamping installation is more reliable, however, the coil support will further increase the through hole, further reducing the strength of the shell, and affecting the quality of the electronic equipment product.

[0048] Based on this, the embodiment of the present application provides an electronic device.

[0049] The technical solutions of the present application will be further described below with reference to the embodiments and drawings.

[0050] Embodiment

[0051] Please refer to the accompanying Figure 1 to the accompanying Figure 5 The embodiment of the present application discloses an electronic device, comprising: a shell 10, the shell 10 has a bottom plate 11 and a side plate 12 connected with the bottom plate 11;

[0052] The outer surface of the side plate 12 is formed with a first groove 121, and the bottom of the first groove 121 is provided with a threading hole 1211, the area of the threading hole 1211 is smaller than the area of the opening of the first groove 121;

[0053] The charging transmission coil 20 is embedded in the first groove 121, and the electric connection line 21 of the charging transmission coil 20 enters the shell 10 through the threading hole 1211.

[0054] Specifically, the shell 10 is an external structure for protecting the internal components of the electronic device, which takes into account a certain aesthetic while needing to play a role in dust removal, waterproofing and protection against external impact for internal electronic components, which can avoid damage to internal electronic components, and also has a certain electromagnetic shielding effect, preventing external electromagnetic interference and reducing internal electromagnetic signal leakage. The shell 10 is usually made of metal materials such as aluminum alloy, stainless steel, etc., or plastic materials such as ABS (Acrylonitrile Butadiene Styrene), PC (Polycarbonate), etc., which are low in cost and light in weight, but relatively weak in strength and heat dissipation performance, and can also be composite materials such as carbon fiber. The shell 10 can be a box-shaped structure, which has at least one bottom plate 11 and one side plate 12 connected with the bottom plate 11, and needs to fix and install the charging transmission coil 20 thereon.

[0055] For the shell 10, other conditions being unchanged, the larger the area of the opening on the shell 10, the lower the strength of the shell 10. As the opening size increases, the effective area of the shell 10 available to withstand the load decreases, which can cause the local stress to increase significantly. This stress concentration phenomenon is particularly evident at the opening edge, making the shell 10 more prone to deformation or damage in these areas; the larger the opening, the higher the stress concentration factor of the shell 10, and the local membrane stress and bending stress at the opening edge will also increase significantly. For example, in a pressure vessel, the larger the opening diameter, the more obvious the stress concentration phenomenon at the hole edge, and the local stress can reach several times the material yield strength, directly affecting the quality and service life of the shell 10; the larger the opening, the more likely the shell 10 and other structures will deform inconsistently under load, further increasing the stress at the opening. This discontinuity is particularly pronounced in large opening structures, further weakening the overall strength of the shell 10.

[0056] The electronic device provided in the embodiments of the present application no longer needs to open a hole in the bottom plate 11 for installation of the charging transmitting coil 20, but forms a first recess 121 on the outer surface of the side plate 12, and the opening of the first recess 121 faces the outside of the shell 10, so that the charging transmitting coil 20 can be installed from the outside. A threading hole 1211 can be formed at the bottom of the first recess 121, and the threading hole 1211 only needs to pass the electric connection wire 21 of the charging transmitting coil 20, so that the area of the opening of the shell 10 can be greatly reduced, and the opening size can be greatly reduced. Compared with the prior art, the bottom plate 11 needs to be provided with a through hole through which the entire charging transmitting coil 20 can pass, and the embodiments of the present application only need to provide a threading hole 1211 through which the electric connection wire can pass, so that the opening area of the shell 10 can be greatly reduced, the strength of the shell 10 can be effectively increased, and the shell 10 can be prevented from being damaged, cracked, etc. due to insufficient strength during transportation and use, the product quality can be improved, and the user experience can be ensured.

[0057] The electronic device can be a tablet computer, specifically an educational tablet, which is equipped with a charging pen to make it more convenient for users to use, and the body of the electronic device can charge the charging pen, so that the charging pen can be easily prepared, and the electronic device is more popular with users.

[0058] The electronic device can also be an electronic watch, a mobile phone, etc., which is not limited here.

[0059] According to the electronic equipment provided in the embodiment of the present application, the first groove 121 is formed on the outer surface of the side plate 12 of the shell 10, the charging transmitting coil 20 is accommodated through the first groove 121, and only a threading hole 1211 capable of allowing the charging transmitting coil 20 to pass through needs to be arranged at the bottom of the first groove 121, so that the hole of the shell 10 is not excessively large, the overall strength of the shell 10 is not affected, the product quality is not reduced, and the use experience of the user is not affected.

[0060] In some embodiments, the threading hole 1211 is a strip-shaped hole.

[0061] The two ends of the strip-shaped hole along the length direction thereof correspond to the two electric connection lines 21 that are farthest apart.

[0062] Specifically, the threading hole 1211 can be one, which can be a strip-shaped hole, the strip-shaped hole can be a hole extending along a straight line through the plate body of the side plate 12, and the two ends of the strip-shaped hole along the length direction thereof correspond to the two electric connection lines 21 that are farthest apart, so that the electric connection lines 21 of the charging transmitting coil 20 can smoothly enter the shell 10 from the strip-shaped hole, and the electric connection lines 21 will not be bent at the bottom of the first groove 121, thereby affecting the connection function of the electric connection lines 21.

[0063] The strip-shaped hole passes through the plate body of the side plate 12 and has a length direction and a width direction perpendicular to each other on the surface of the side plate 12.

[0064] In some embodiments, the width of the threading hole 1211 is the same or gradually decreases from the outer surface to the inner surface of the side plate 12.

[0065] The width of the one end of the threading hole 1211 away from the charging transmitting coil 20 is greater than the diameter of the electric connection line 21.

[0066] Specifically, the width of the strip-shaped hole can be the same or gradually decreases from the outer surface to the inner surface of the side plate 12.

[0067] The width of the strip-shaped hole gradually decreases from the outside to the inside, so that the one end of the strip-shaped hole connecting the first groove 121 has a relatively large opening, the operator can more conveniently align the electric connection line 21 and the strip-shaped hole when performing the installation operation, and the electric connection line 21 can be more quickly and accurately inserted into the strip-shaped hole and then into the shell 10, so that the assembly difficulty can be effectively reduced and the assembly efficiency can be improved. The one end of the strip-shaped hole connecting the inside of the shell 10 has a relatively small opening, which can be adapted to the diameter of the electric connection line 21 or slightly larger than the diameter of the electric connection line 21, so that the electric connection line 21 can normally pass through, and the hole of the side plate 12 can be as small as possible, thereby further improving the strength of the shell 10.

[0068] In some embodiments, the number of threading holes 1211 is multiple, and the number of electric connection wires 21 is multiple;

[0069] The multiple electric connection wires 21 are threaded one by one in the threading holes 1211.

[0070] Specifically, the number of threading holes 1211 can also be multiple, and each threading hole 1211 corresponds to one electric connection wire 21, so that each threading hole 1211 can be correspondingly formed in the shape of the radial cross section of the electric connection wire 21. One electric connection wire 21 passes through one threading hole 1211, which can reduce the total hole area on the shell 10 compared to a strip-shaped hole on the side plate 12, thereby further improving the strength of the shell 10.

[0071] The shape of the threading hole 1211 can correspond to the radial cross section of the electric connection wire 21, and the specific shape can be circular, oval, etc., which is not limited here.

[0072] In some embodiments, the cross-sectional area of the threading hole 1211 is the same or gradually decreases from the outer surface to the inner surface of the side plate 12;

[0073] And the cross-sectional area of the end of the threading hole 1211 away from the charging transmission coil 20 is greater than the radial cross-sectional area of the electric connection wire 21.

[0074] Specifically, since the threading hole 1211 corresponds to the electric connection wire 21 one by one, the threading hole 1211 needs to be threaded with each electric connection wire 21, and the threading hole 1211 can be designed as a hole with a cross-sectional area that gradually decreases from the outside to the inside, which can make the end of the threading hole 1211 connected to the first groove 121 have a larger opening, so that the operator can more easily align the electric connection wire 21 and the threading hole 1211 when installing, and more quickly and accurately insert the electric connection wire 21 into the threading hole 1211 and then into the inside of the shell 10, which can effectively reduce the assembly difficulty and improve the assembly efficiency. The end of the threading hole 1211 connected to the inside of the shell 10 has a smaller opening, which can be adapted to the radial cross section of the electric connection wire 21 or slightly larger than the radial cross section of the electric connection wire 21, which can ensure that the electric connection wire 21 can pass normally. The hole of the side plate 12 can be as small as possible, thereby further improving the strength of the shell 10.

[0075] Wherein, the radial cross section refers to the cross section taken along the radial direction of the electric connection wire.

[0076] In some embodiments, the inner surface of the side plate 12 is formed with a second groove 122, and the position of the second groove 122 corresponds to the position of the first groove 121;

[0077] Wherein, the threading hole 1211 penetrates the bottom of the second groove 122.

[0078] Specifically, please refer to the attached Figure 5 The second groove 122 is located on the inner surface of the side plate 12. When the shell 10 is processed, a second groove 122 can be formed at the corresponding position first. After the second groove 122 is formed, a threading hole 1211 is processed at the bottom of the second groove 122, so that the threading hole 1211 communicates with the bottom of the first groove 121. Through the arrangement of the second groove 122, the threading hole 1211 can be more easily penetrated through the side wall, and the threading hole 1211 can be positioned, thereby reducing the processing difficulty of the threading hole 1211.

[0079] In some embodiments, the outer surface of the side plate 12 is formed with a third groove 123, and the first groove 121 is located at the bottom of the third groove 123.

[0080] The electronic device further comprises a decorative plate 30, which is embedded in the third groove 123. The decorative plate 30 is connected with the inner wall of the third groove 123, and the decorative plate 30 is also connected with the charging transmitting coil 20 by pasting.

[0081] Specifically, the shape of the third groove 123 can be adapted to the shape of the decorative plate 30, which can be rectangular, circular, etc. Here, no limitation is made. The depth of the third groove 123 can be adapted to the thickness of the decorative plate 30, so that the decorative plate 30 can be embedded in the third groove 123. The decorative plate 30 and the third groove 123 can be connected by pasting with glue, or by a clamping structure, bolt fixing, etc. Here, no limitation is made. After the decorative plate 30 is embedded in the third groove 123 and fixedly connected with the inner wall of the third groove 123, it can be pasted with the charging transmitting coil 20, which can further improve the fixing strength of the decorative plate 30 and avoid the decorative plate 30 from falling off.

[0082] Specifically, when the decorative plate 30 is pasted with the charging transmitting coil 20, it can be pasted with glue or adhesive tape. Here, no limitation is made.

[0083] In some embodiments, the part of the electric connecting wire 21 located in the shell 10 is pasted with the inner surface of the bottom plate 11.

[0084] Specifically, the electric connecting wire 21 extends from the charging transmitting coil 20, enters the shell 10 from the threading hole 1211, and is connected to the circuit board in the shell 10. A part of the electric connecting wire 21 located in the shell 10 is fixed by pasting, and is pasted to the inner surface of the bottom plate 11. This can avoid the electric connecting wire 21 from shaking, and can avoid the electric connecting wire 21 from being damaged or emitting a sound, thereby affecting the user's experience.

[0085] The electric connecting wire 21 can be connected to the inner surface of the bottom plate 11 by adhesive paper, or by glue, and the specific connection method is not limited.

[0086] In some embodiments, the threading hole 1211 is formed with an arc-shaped chamfer at the inlet end and the outlet end thereof.

[0087] Specifically, the arc-shaped chamfer has a smooth arc surface, which can avoid the electric connecting wire 21 being scratched at the inlet end and / or the outlet end of the threading hole 1211, so as to avoid damaging the electric connecting wire 21 and affecting the normal function of the electric connecting wire 21.

[0088] In some embodiments, the electronic device further comprises:

[0089] The to-be-charged member 50 is provided with a charging receiving coil 501.

[0090] The magnetic assembly 40 is arranged between the side plate 12 of the shell 10 and the to-be-charged member 50, so that the to-be-charged member 50 can be adsorbed to the side plate 12.

[0091] When the to-be-charged member 50 is adsorbed to the side plate 12, the charging transmitting coil 20 cooperates with the charging receiving coil 501 to charge the to-be-charged member 50.

[0092] Specifically, the working principle of the wireless charging system is based on electromagnetic induction. The alternating magnetic field generated by the transmitting coil transmits energy to the receiving coil through inductive coupling. The charging transmitting coil 20 is the transmitting end in the wireless charging system, and its main function is to convert electrical energy into electromagnetic field and emit it. When alternating current passes through the transmitting coil, an alternating magnetic field is generated. The charging receiving coil 501 is the receiving end in the wireless charging system, and its main function is to induce the magnetic field generated by the transmitting coil and convert it into electrical energy to charge the device. Through the cooperation of the charging transmitting coil 20 and the charging receiving coil 501, the to-be-charged member 50 can be charged by the electronic device when the to-be-charged member 50 is in contact with the electronic device.

[0093] The electronic device can be a tablet computer, and the to-be-charged member 50 can be a charging pen. When the charging pen is attached to the side plate 12 of the tablet computer, the charging pen can be charged, and the charging process of the charging pen can be simple and easy to operate through this wireless charging method.

[0094] The tablet computer can be an educational tablet, which is not limited here.

[0095] On the two sides of the axial direction of the charging transmitting coil 20, two magnet assemblies can also be arranged, which are respectively arranged on the inner side of the side plate 12 and can be embedded into the two ends of the charging transmitting coil 20 along the axial direction thereof and then fixed by glue-dropping. By increasing the magnets, not only the adsorption effect can be achieved, but also the electronic device can be positioned to the charging piece 50, so that the charging piece 50 is fixed at the position of the charging transmitting coil 20 and is attached to the side of the electronic device at the position, so that the charging transmitting coil 20 and the charging receiving coil 501 can cooperate with each other, and the charging piece 50 can not easily fall off during charging. By the magnets, the magnetic flux between the charging transmitting coil 20 and the charging receiving coil 501 can be increased, the magnetic field energy can be more concentratedly transmitted to the receiving end, the leakage and scattering of the magnetic field can be reduced, and thus the energy transmission efficiency can be improved.
