Description

Technical Field

[0001] The present application relates to the technical field of electronic products, and in particular to an electronic device. Background Art

[0002] With the advancement of technology, mobile phones and other electronic devices are becoming increasingly common in daily life. Mobile phone motherboards have a small footprint, with concentrated heat sources. The charging chip and system-on-chip (SOC) are located in close proximity. During screen-on charging, the charging chip generates significant heat, impacting SOC performance. The SOC typically limits the charging speed during screen-on charging to reduce heat generation. To increase screen-on charging speed while minimizing heat generation, the priority charging circuit is typically split into two parallel circuits. However, this additional charging circuit can easily interfere with other components within the phone, occupying space for these components and reducing the overall competitiveness of the electronic device's architecture. Utility Model Content

[0003] In view of this, an embodiment of the present application provides an electronic device to solve the technical problem in the prior art that the charging circuit of the electronic device easily interferes with other components, squeezes the space of other components, and reduces the competitiveness of the overall architecture of the electronic device.

[0004] In a specific embodiment, the electronic device includes: a shell and a screen, a accommodating cavity is provided between the shell and the screen, the screen includes a display panel and a functional layer, the functional layer is provided with a circuit, a battery and at least one charging chip, the battery and the charging chip are located in the accommodating cavity, at least one of the charging chips includes a first charging chip, wherein the functional layer has a first connection end and a second connection end, the first charging chip is electrically connected to the first connection end, and the battery is electrically connected to the second connection end, so that the first charging chip and the battery are electrically connected through the circuit of the functional layer, and the projection of at least one of the first connection end and the second connection end along the thickness direction of the electronic device is located within the projection range of the display panel.

[0005] In this embodiment, the first connection end and the second connection end of the functional layer are used to electrically connect the first charging chip and the battery, respectively, and the functional layer is located within the screen. In other words, the first charging chip and the battery are electrically connected through the functional layer. Since the functional layer is built into the screen, there is no problem of interfering with other components within the accommodating cavity or occupying the space of other components, thus ensuring the competitiveness of the entire architecture of the electronic device. At the same time, the line width setting of the circuit on the functional layer used to electrically connect the first charging chip and the battery is not restricted, so that the line width of the circuit connecting the first charging chip and the battery can be larger, so that the circuit can flow a larger current, thereby improving the charging speed of the electronic device when the screen is on. In addition, connecting the battery and the first charging chip through the functional layer within the screen can keep the heat generated during charging away from the SOC chip located on the motherboard, reducing the impact on the SOC chip and preventing the SOC chip from limiting the charging speed.

[0006] In a specific embodiment, the first connection end has a preset distance from the end of the functional layer along the length direction or width direction of the electronic device, and / or the second connection end has a preset distance from the end of the functional layer along the length direction or width direction of the electronic device.

[0007] In a first specific embodiment, when the first charging chip is located in the middle position of the accommodating cavity and the battery is located at the edge position of the accommodating cavity, the first connection end can have a preset distance from the end of the functional layer (along the length direction or width direction), so that the first connection end is closer to the first charging chip along the length direction or width direction of the electronic device, and there is no need to set a longer first connection end, which can simplify the structure of the functional layer and reduce losses. At the same time, the second connection end can be connected to the end of the functional layer, so that the second connection end is closer to the battery along the length direction or width direction of the electronic device, and there is no need to set a longer second connection end, which can simplify the structure and reduce losses.

[0008] In a second specific embodiment, when the first charging chip is located at the edge of the accommodating cavity and the battery is located in the middle of the accommodating cavity, the first connection end can be connected to the end of the functional layer so that the first connection end is closer to the first charging chip along the length direction or width direction of the electronic device, and there is no need to set a longer first connection end, which can simplify the structure and reduce losses. At the same time, the second connection end can have a preset distance from the end of the functional layer (along the length direction or width direction) so that the second connection end is closer to the battery along the length direction or width direction of the electronic device, and there is no need to set a longer second connection end, which can simplify the structure of the functional layer and reduce losses.

[0009] In a third specific embodiment, when the first charging chip and the battery are both arranged in the middle position of the accommodating cavity, the first connection end and the second connection end are both at a preset distance from the end of the functional layer (along the length direction or the width direction), so that along the length direction or the width direction of the electronic device, the first connection end is closer to the first charging chip and the second connection end is closer to the battery. There is no need to set longer first connection end and second connection end, which can simplify the structure of the functional layer and reduce losses.

[0010] In a specific embodiment, the first connection end extends relative to the functional layer toward the first charging chip, and the second connection end extends relative to the functional layer toward the battery.

[0011] In this embodiment, because the functional layer is located within the screen, along the thickness direction of the electronic device, the functional layer is at a predetermined distance from the plane where the first charging chip and the battery are located. Therefore, the first connecting end is extended relative to the functional layer toward the first charging chip to enable electrical connection with the first charging chip. Specifically, the first connecting end can be bent relative to the functional layer, while the second connecting end is extended relative to the functional layer toward the battery to enable electrical connection with the battery. Specifically, the second connecting end can be bent relative to the functional layer.

[0012] In a specific embodiment, the first connection end and the second connection end each include a first portion and a second portion connected to each other, the first portion extending along a thickness direction of the electronic device, and the second portion extending along a length direction or a width direction of the electronic device.

[0013] In this embodiment, the functional layer is disposed within the screen, thereby providing a spacing between the functional layer and the first charging chip along the thickness of the electronic device. This allows the first connection terminal to include a first portion, allowing the first connection terminal to extend through the screen to the location of the first charging cell. Furthermore, the first connection terminal also includes a second portion connected to the first portion, thereby increasing the contact area between the first connection terminal and the first charging chip and improving the reliability and stability of the connection between the first connection terminal and the first charging chip. Furthermore, along the thickness of the electronic device, a spacing is provided between the functional layer and the battery. This allows the second connection terminal to include a first portion, allowing the second connection terminal to extend through the screen to the location of the battery and further includes a second portion connected to the first portion, thereby increasing the contact area between the second connection terminal and the battery and improving the reliability and stability of the connection between the second connection terminal and the battery.

[0014] In a specific embodiment, the functional layer is provided with a first through hole and a second through hole, the first connection end is provided on the side wall of the first through hole, the second connection end is provided on the side wall of the second through hole, and the first connection end, the second connection end and the functional layer are integrally formed.

[0015] In this embodiment, when both the first and second connection ends are at a predetermined distance from the ends of the functional layer along the length or width direction, the first and second connection ends can be formed by bending a portion of the functional layer structure so that the first and second connection ends can extend relative to the functional layer, which has the advantages of a simple structure and ease of implementation. Furthermore, after the portion of the functional layer structure is bent to form the first connection end, a first through-hole is formed at a corresponding position of the functional layer, and the first connection end is disposed on a sidewall of the first through-hole. Simultaneously, after the portion of the functional layer structure is bent to form the second connection end, a second through-hole is formed at a corresponding position of the functional layer, and the second connection end is disposed on a sidewall of the second through-hole. This allows the first connection end, the second connection end, and the functional layer to form an integrally formed structure, thereby improving the connection reliability among the first connection end, the second connection end, and the functional layer.

[0016] In a specific embodiment, the first through hole and the second through hole are filled with a filling member.

[0017] In this embodiment, fillers may be provided in the first through hole and the second through hole so that when the screen is assembled, other components in the screen can abut against the fillers, thereby improving the flatness of the screen and ensuring the display effect of the screen.

[0018] In a specific embodiment, the screen also includes a bottom supporting layer, the functional layer is located between the display panel and the bottom supporting layer, the bottom supporting layer is provided with a third through hole and a fourth through hole, the first connection end extends to the first charging chip through the third through hole, and the second connection end extends to the battery through the fourth through hole.

[0019] In this embodiment, when the functional layer is positioned between the display panel and the bottom support layer, a predetermined distance exists between the functional layer and the first charging chip and the battery. The bottom support layer includes a third through-hole, allowing the first connection terminal to extend through the third through-hole to the first charging chip, and a fourth through-hole, allowing the second connection terminal to extend through the fourth through-hole to the battery, thereby achieving an electrical connection between the first charging chip and the battery. Furthermore, the bottom support layer protects and supports the entire screen and improves the flatness of the display panel, thereby enhancing the display quality of the display panel.

[0020] In a specific embodiment, the functional layer is located at the bottom layer of the screen, and the functional layer abuts and is electrically connected to both the first charging chip and the battery.

[0021] In this embodiment, the functional layer is positioned in contact with the first charging chip and the battery, eliminating the need for the first and second connection terminals on the functional layer to bend or extend relative to the functional layer. This further simplifies the structure of the functional layer. A backing film can also be provided between the functional layer and the display panel to provide support and protection for the display panel. Furthermore, in addition to connecting the first chip and the battery, the functional layer provided at the bottom of the screen also provides protection and support for the entire screen and improves the flatness of the display panel, thereby enhancing the display quality.

[0022] In a specific embodiment, the ratio of the area covered by the circuit on the functional layer to the surface area of ​​the functional layer is 0.5-0.9.

[0023] In this embodiment, the ratio of the area covered by the circuit on the functional layer to the surface area of ​​the functional layer can be 0.5-0.9 to improve the current-carrying capacity of the circuit on the functional layer. Specifically, the ratio of the area covered by the circuit on the functional layer to the surface area of ​​the functional layer can be 0.5, 0.6, 0.7, 0.8, 0.9, etc.

[0024] In a specific embodiment, the electronic device further includes a wireless charging coil located in the accommodating cavity, and at least one of the charging chips further includes a second charging chip, the second charging chip is electrically connected to the battery through a charging circuit, and the charging circuit is located on the outside of the wireless charging coil along the length direction or width direction of the electronic device.

[0025] In this embodiment, the electronic device may further include a wireless charging coil located within the accommodating cavity and a wireless charging receiver chip connected thereto. The wireless charging coil is used to wirelessly charge the electronic device. The wireless charging coil is capable of generating electromagnetic induction with a coil within the wireless charger, thereby generating an induced current. The wireless charging receiver chip is used to manage and convert the induced current generated by the wireless charging coil. In this embodiment, the charging circuit connecting the second charging chip to the battery is located outside the wireless charging coil along the length or width of the electronic device, thereby avoiding interference with the wireless charging coil. Furthermore, since the charging circuit is located within the accommodating cavity, there is no need to provide features such as a bend or extension along the thickness of the electronic device on the charging circuit. This simplifies the structure of the charging circuit and reduces losses during charging.

[0026] In a specific embodiment, the functional layer is made of polyimide material or polyphenylene sulfone resin material.

[0027] In this embodiment, the functional layer can be a polyimide material or a polyphenylene sulfone resin material. Both polyimide material and polyphenylene sulfone resin material are colorless and transparent materials with good thermal stability and good insulation, so that the functional layer can meet the use requirements of the screen. In addition, both polyimide material and polyphenylene sulfone resin material have good mechanical properties and can protect and support the display panel in the screen, thereby improving the overall flatness of the screen and thus improving the display effect.

[0028] In a specific embodiment, the surface area of ​​the functional layer is the same as the surface area of ​​the display panel.

[0029] In this embodiment, the surface area of ​​the functional layer can be the same as that of the display panel, so that the functional layer can provide support for the entire area of ​​the display panel, improving the overall flatness of the display panel and thus enhancing the display quality of the display panel. In addition, the functional layer does not extend beyond the display panel, thereby reducing the risk of interference between the functional layer and other components of the electronic device.

[0064] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0065] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0066] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described based on the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that a component is connected to another component "upper" or "lower", it can not only be directly connected to the other component "upper" or "lower", but also indirectly connected to the other component "upper" or "lower" through an intermediate component.

[0067] like Figure 1 As shown, Figure 1 : This is a schematic diagram of the structure of an electronic device 1 in a specific embodiment. Electronic devices include, for example, mobile phones, tablet computers, personal digital assistants (PDAs), laptop computers, car computers, foldable display devices, foldable screens, wearable devices, and any other device with a screen function. The embodiments of this application do not impose any particular restrictions on the specific form of the above-mentioned electronic devices. For the sake of convenience, the following description is based on the example of a mobile phone as the electronic device. The following describes the electronic device 1 of this application using a specific embodiment.

[0068] In daily use, electronic devices may charge while the screen is on, such as when the user is watching a video or playing a game. In such scenarios, since the screen of the electronic device is on, the SOC chip in the electronic device's motherboard will heat up. Since the electronic device is charging, the charging circuit will also heat up, resulting in a high temperature on the electronic device's motherboard, which can easily trigger the SOC chip to limit the charging speed of the charging circuit to reduce the generated heat. To increase the charging speed while reducing heat generation, the wired charging circuit is usually divided into two parallel circuits. However, the newly added charging circuit is prone to interference with other components in the mobile phone, occupying the space of other components and reducing the competitiveness of the overall architecture of the electronic device. In addition, due to the limited layout space, the newly added charging circuit cannot be increased in width, resulting in a small current flowing through the charging circuit. As a result, the charging speed of the electronic device is still low when the screen is on, and the problem of high heat generation when the screen is on still exists.

[0069] In order to solve the above technical problems, the embodiment of the present application provides an electronic device 1, such as Figure 2 As shown, Figure 2 for Figure 1 A cross-sectional view in a specific embodiment. The electronic device 1 includes a housing 11 and a screen 12. In some embodiments, the electronic device may include 1 or N screens, where N is a positive integer greater than 1. A accommodating cavity 13 is provided between the housing 11 and the screen 12, and the screen 12 includes a display panel 121 and a functional layer 17. The display panel is used to display images and / or videos, and may be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), Miniled, MicroLed, Micro-oLed, a quantum dot light-emitting diode (QLED), etc.

[0070] like Figure 2As shown, a circuit is provided on the functional layer 17, and a battery 14 and at least one charging chip are also provided in the accommodating cavity 13. The at least one charging chip may include a first charging chip 15. The functional layer 17 has a first connection terminal 171 and a second connection terminal 172. The first charging chip 15 is electrically connected to the first connection terminal 171, and the battery 14 is electrically connected to the second connection terminal 172. The first charging chip 15 and the battery 14 are electrically connected via the circuit on the functional layer 17. The projection of at least one of the first connection terminal 171 and the second connection terminal 172 along the thickness direction of the electronic device 1 is located within the projection range of the display panel 121.

[0071] In this embodiment, the first connection end 171 and the second connection end 172 of the functional layer 17 are respectively used to electrically connect the first charging chip 15 and the battery 14. The functional layer 17 is located within the screen 12. That is, the first charging chip 15 and the battery 14 are electrically connected via the functional layer 17. Because the functional layer 17 is built into the screen 12, there is no interference with or space occupation by other components within the accommodating cavity 13, thus preventing the electronic device's architectural competitiveness from being compromised. Furthermore, the line width of the circuit on the functional layer 17 used to electrically connect the first charging chip 15 and the battery 14 is unrestricted, allowing for a larger line width, allowing for a larger current to flow through the circuit, thereby improving the charging speed of the electronic device 1 when the screen is on. Furthermore, connecting the battery 14 and the first charging chip 15 via the functional layer 17 within the screen 12 directs heat generated during charging away from the SOC chip located on the motherboard, minimizing its impact on the SOC chip and preventing the SOC chip from limiting the charging speed.

[0072] In the above embodiment, the functional layer 17 can be a polyimide material or a polyphenylene sulfone resin material. Both the polyimide material and the polyphenylene sulfone resin material are colorless and transparent materials with good thermal stability and good insulation, so that the functional layer 17 can meet the use requirements of the screen 12, and both the polyimide material and the polyphenylene sulfone resin material have good mechanical properties, which can protect and support the display panel 121 in the screen 12, improve the overall flatness of the screen 12, and thus improve the display effect.

[0073] The circuit connecting the first charging chip 15 and the battery 14 includes but is not limited to being fixedly connected to the functional layer through a silk screen process.

[0074] In the above embodiments, the ratio of the area covered by the circuit on the functional layer 17 to the surface area of ​​the functional layer 17 can be 0.5-0.9 to improve the current-carrying capacity of the circuit on the functional layer 17. Specifically, the ratio of the area covered by the circuit on the functional layer 17 to the surface area of ​​the functional layer 17 can be 0.5, 0.6, 0.7, 0.8, 0.9, etc.

[0075] In the above embodiments, the surface area of ​​the functional layer 17 can be the same as the surface area of ​​the display panel 121, so that the functional layer 17 can support the entire area of ​​the display panel 121, improve the overall flatness of the display panel 121, and thus improve the display effect of the display panel 121. In addition, the functional layer 17 does not extend beyond the display panel 121, thereby reducing the risk of interference between the functional layer 17 and other components of the electronic device 1.

[0076] In a specific embodiment, Figure 2 As shown, the first connection end 171 extends relative to the functional layer 17 toward the first charging chip 15 , and the second connection end 172 extends relative to the functional layer 17 toward the battery 14 .

[0077] In this embodiment, because the functional layer 17 is located within the screen 12, along the thickness direction of the electronic device 1, there is a predetermined distance between the functional layer 17 and the plane where the first charging chip 15 and the battery 14 are located. Therefore, the first connection end 171 is extended relative to the functional layer 17 toward the first charging chip 15 to enable electrical connection between the first connection end 171 and the first charging chip 15. Specifically, the first connection end 171 can be bent relative to the functional layer 17, while the second connection end 172 is extended relative to the functional layer 17 toward the battery 14 to enable electrical connection between the second connection end 172 and the battery 14. Specifically, the second connection end 172 can be bent relative to the functional layer 17.

[0078] In the above embodiments, a predetermined distance may be formed between the first connection end 171 and the end of the functional layer 17 along the length or width direction, and / or a predetermined distance may be formed between the second connection end 172 and the end of the functional layer 17 along the length or width direction. Three embodiments are described in detail below.

[0079] Specifically, if Figure 3 In the embodiment shown, Figure 3 This is a structural schematic diagram of the functional layer 17 in the electronic device provided in the present application in a specific embodiment. When the first charging chip is located in the middle position of the accommodating cavity and the battery is located at the edge position of the accommodating cavity, the first connection end 171 can have a preset distance from the end of the functional layer 17 (along the length direction or width direction), so that the first connection end 171 is closer to the first charging chip along the length direction or width direction of the electronic device, and there is no need to set a longer first connection end 171, which can simplify the structure of the functional layer and reduce losses. At the same time, the second connection end 172 can be connected to the end of the functional layer 17, so that the second connection end 172 is closer to the battery along the length direction or width direction of the electronic device, and there is no need to set a longer second connection end 172, which can simplify the structure and reduce losses.

[0080] In another specific embodiment, when the first charging chip is located at the edge of the accommodating cavity and the battery is located in the middle of the accommodating cavity, the first connection end 171 can be connected to the end of the functional layer 17 (not shown in the figure) so that the first connection end is closer to the first charging chip along the length direction or width direction of the electronic device, and there is no need to set a longer first connection end 171, which can simplify the structure and reduce losses. At the same time, the second connection end 172 can have a preset distance from the end of the functional layer 17 (along the length direction or width direction) so that the second connection end 172 is closer to the battery along the length direction or width direction of the electronic device, and there is no need to set a longer second connection end 172, which can simplify the structure of the functional layer 17 and reduce losses.

[0081] In another specific embodiment, Figure 2 and Figure 4 In the embodiment shown, Figure 4 for Figure 2 Schematic diagram of the structure of the middle functional layer 17. When the first charging chip 15 and the battery 14 are both arranged in the middle position of the accommodating cavity 13, the first connection end 171 and the second connection end 172 are both at a preset distance from the end of the functional layer 17 (along the length direction or width direction), so that along the length direction or width direction of the electronic device 1, the first connection end 171 is closer to the first charging chip 15, and the second connection end 172 is closer to the battery 15. There is no need to set longer first connection end 171 and second connection end 172, which can simplify the structure of the functional layer 17 and reduce losses.

[0082] The specific structures of the first connection end 171 and the second connection end 172 of the functional layer 17 are described in detail below.

[0083] In a specific embodiment, Figure 2 、 Figure 5 and Figure 6 As shown, Figure 5 for Figure 2 A partial enlarged view of part I, Figure 6 for Figure 2 In the partially enlarged view of part II, the first connecting end 171 and the second connecting end 172 both include a first part 173 and a second part 174 connected to each other. The first part 173 extends along the thickness direction of the electronic device 1, and the second part 174 extends along the length direction or width direction of the electronic device 1.

[0084] In this embodiment, the functional layer 17 is arranged in the screen 12, so that there is a distance between the functional layer 17 and the first charging chip 15 along the thickness direction of the electronic device 1, so that the first connection end 171 includes a first part 173, so that the first connection end 171 can extend out of the screen 12 to the position of the first charging cell 15 through the first part 173, and the first connection end 171 also includes a second part 174 connected to the first part 173, so as to increase the contact area between the first connection end 171 and the first charging chip 15, thereby improving the connection reliability and stability between the first connection end 171 and the first charging chip 15. At the same time, along the thickness direction of the electronic device 1, there is a distance between the functional layer 17 and the battery 14, so that the second connection end 172 includes a first part 173, so that the second connection end 172 can extend from the screen 12 to the location of the battery through the first part 173, and the second connection end also includes a second part 174 connected to the first part 173, so as to increase the contact area between the second connection end 172 and the battery 14, thereby improving the connection reliability and stability between the second connection end 172 and the battery 14.

[0085] In a specific embodiment, Figure 4 As shown, the functional layer 17 is provided with a first through hole 175 and a second through hole 176. The first connection end 171 is provided on the side wall of the first through hole 175, and the second connection end 172 is provided on the side wall of the second through hole 176. The first connection end 171, the second connection end 172 and the functional layer 17 are integrally formed. The first connection end 171 is formed by opening the first through hole 175 in the functional layer 17 and bending it, and the second connection end 172 is formed by opening the second through hole 176 in the functional layer 17 and bending it.

[0086] In this embodiment, when both the first connection end 171 and the second connection end 172 are at a predetermined distance from the ends of the functional layer 17 along the length or width direction, the first connection end 171 and the second connection end 172 can be formed by bending a portion of the functional layer 17 so that the first connection end 171 and the second connection end 172 can extend relative to the functional layer 17. This has the advantages of a simple structure and ease of implementation. Furthermore, after the portion of the functional layer 17 is bent to form the first connection end 171, a first through-hole 175 is formed at a corresponding position of the functional layer 17. The first connection end 171 is disposed on the sidewall of the first through-hole 175. Furthermore, after the portion of the functional layer 17 is bent to form the second connection end 172, a second through-hole 176 is formed at a corresponding position of the functional layer 17. The second connection end 172 is disposed on the sidewall of the second through-hole 176. This allows the first connection end 171, the second connection end 172, and the functional layer 17 to form an integrally formed structure, thereby improving the connection reliability among the first connection end 171, the second connection end 172, and the functional layer 17.

[0088] The filling piece may be a thermally conductive gel, which is a colorless and transparent material with good electrical insulation, vibration absorption and stability, and can meet the use requirements of the screen 12 .

[0090] In this embodiment, when functional layer 17 is positioned between display panel 121 and bottom supporting layer 122, a predetermined distance exists between functional layer 17 and the first charging chip and battery. This allows bottom supporting layer 122 to have a third through-hole, allowing first connection end 171 to extend through the third through-hole to the first charging chip. Furthermore, bottom supporting layer 122 also allows second connection end 172 to extend through the fourth through-hole to the battery, thereby achieving an electrical connection between the first charging chip and the battery. Furthermore, bottom supporting layer 122 protects and supports the entire screen 12 and improves the flatness of display panel 121, thereby enhancing the display quality of display panel 121.

[0091] In another specific embodiment, Figure 8 As shown, Figure 8 This is a structural diagram of the screen 12 in another specific embodiment of the electronic device provided in this application. The functional layer 17 can also be located at the bottom layer of the screen 12 so that the functional layer 17 abuts and is electrically connected to the first charging chip and the battery.

[0092] In this embodiment, the functional layer 17 is in contact with the first charging chip and the battery, eliminating the need for the first and second connection ends on the functional layer to bend or extend relative to the functional layer 17, further simplifying the structure of the functional layer 17. A backing film 124 may also be provided between the functional layer 17 and the display panel 121 to provide support and protection for the display panel 121. Furthermore, in addition to connecting the first chip and the battery, the functional layer provided at the bottom of the screen also provides protection and support for the entire screen 12, and improves the flatness of the display panel 121, thereby enhancing the display quality of the display panel 121.

[0093] In the above embodiment, if Figure 7 and Figure 8 As shown, a cover plate 123 may also be provided on the top of the screen 12 to protect the display panel 121 and prevent the display panel 121 from direct contact with the outside world. The bottom support layer 123 in the above embodiment may include components such as grid glue, foam glue and copper foil, wherein the grid glue is used to bond the module material, the foam glue improves the impact resistance of the bottom support layer 123, and the copper foil is used to protect and support the display panel to avoid film printing, and can improve the heat dissipation effect of the screen and play a role in electrostatic protection. In addition, components such as the foam glue and grid glue in the bottom support layer 123 can also be replaced with silicone gel with the same impact resistance and bonding ability.

[0094] In the above embodiment, a polarizer or a color filter on encapsulation (COE) may be further provided between the display panel 121 and the cover plate 123 to eliminate the influence of external ambient light and improve the display effect.

[0095] In a specific embodiment, Figure 9 As shown, Figure 9 The figure is a schematic diagram of the structure of an electronic device 1 in a specific embodiment. To improve the charging speed of the electronic device 1 when the screen is on, multiple charging chips can be provided, that is, the battery is electrically connected to multiple charging chips. When the electronic device 1 is charging, after the current flows through the power adapter, the multiple charging chips can collectively charge the battery 14, thereby dispersing the heat generated by the electronic device 1. The multiple charging circuits can also collectively charge the battery 14, reducing the path impedance and improving the charging speed of the electronic device 1 when the screen is on.

[0096] The plurality of charging chips may all be first charging chips whose charging circuit is arranged on the functional layer of the screen. Alternatively, the plurality of charging chips may include at least one first charging chip and at least one second charging chip, wherein the charging circuit of the first charging chip is arranged on the functional layer of the screen, and the charging circuit of the second charging chip is arranged in the accommodating cavity.

[0097] The electronic device 1 may further include a wireless charging coil 18 located within the accommodating cavity 13 and a wireless charging receiver chip 19 connected thereto. The wireless charging coil 18 is used to wirelessly charge the electronic device 1. The wireless charging coil 18 can generate electromagnetic induction with the coil in the wireless charger, generating an induced current. The wireless charging receiver chip 19 is used to manage and convert the induced current generated by the wireless charging coil 18. In this embodiment, the charging circuit connecting the second charging chip 16 and the battery 14 is located outside the wireless charging coil 18 along the length or width of the electronic device 1, thereby avoiding interference with the wireless charging coil 18. Furthermore, since the charging circuit is located within the accommodating cavity, there is no need to provide features such as bends or extensions along the thickness of the electronic device 1. This simplifies the structure of the charging circuit and reduces losses during charging.

[0098] like Figure 10 As shown, Figure 10 This is a schematic diagram of a specific embodiment of the charging architecture of the electronic device 1 provided in this application. The first charging chip 15 is provided with a first voltage conversion circuit and a first charging circuit. The first voltage conversion circuit is used to adjust the current flowing in the first charging circuit. The second charging chip 16 is provided with a second voltage conversion circuit and a second charging circuit. The second voltage conversion circuit is used to adjust the current flowing in the second charging circuit. The electronic device 1 may also be provided with a charging main board and a charging sub-board. Both the charging main board and the charging sub-board are provided in the accommodating cavity and are located on either side of the battery. The first charging chip can be provided on the charging sub-board of the electronic device, and the second charging chip can be provided on the charging main board of the electronic device. The first charging circuit and / or the second charging circuit can be provided on the functional layer.

[0099] In a specific embodiment, Figure 11 As shown, Figure 11 This is a structural diagram of the charging architecture of the electronic device provided in the present application in another specific embodiment, wherein the first charging circuit connected to the first charging chip 15 and the battery 14 can be arranged on the functional layer. When the electronic device is charged with the screen on, the current in the first charging circuit can be set to be larger, and the current in other charging circuits can be set to be smaller, so that the heat generated during the charging process is kept away from the motherboard, thereby avoiding the SOC chip in the motherboard limiting the charging speed in the screen-on state.

[0100] In another specific embodiment, Figure 12 As shown, Figure 12This is a structural diagram of another specific embodiment of the charging architecture in the electronic device provided in the present application, wherein two second charging chips 16 and two correspondingly connected second charging circuits can be provided on the charging mainboard. When charging with the screen off, the provision of two second charging chips 16 and two second charging circuits can reduce the flow impedance and improve the charging power of the electronic device in the screen off state. Specifically, when the second charging chip 16 is a 4:1 charging chip, the charging power in the screen off state can reach 100w.
