[0001] This application claims priority to Chinese Patent Application No. 202510122917.7, filed on January 24, 2025, entitled "Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of electronic product technology, and more particularly to an electronic device. Background Technology
[0003] In modern life, work, and communication, smartwatches, mobile phones, laptops, and other electronic devices are playing an increasingly important role and are gradually becoming necessities for modern people. Taking mobile phones as an example, they have become indispensable tools in both production and daily life.
[0004] As mobile phones need to perform more and more functions, the number of electronic components inside them is also increasing. This increase in electronic components leads to an increase in the thickness and other dimensions of the phone, which contradicts the trend towards thinner and lighter phones. To balance functionality and a slimmer design, battery life may be affected. Therefore, increasing battery life has become a top priority. Summary of the Invention
[0005] This application provides an electronic device that balances the requirements of thinness and lightness with long battery life.
[0006] This application provides an electronic device, including: a housing, a battery, a first display screen, a screen circuit board, and a touch chip. The housing has an installation space, and the first display screen includes a screen mounting portion. The screen circuit board includes a first connecting portion and a first extension portion, which are fixedly connected. The first display screen is disposed in the housing and closes the opening of the installation space. The battery, screen circuit board, screen mounting portion, and touch chip are all disposed within the installation space. The battery, first connecting portion, and screen mounting portion are arranged sequentially along a first direction, and the first connecting portion and screen mounting portion are electrically connected. The first extension portion is located on the side of the first connecting portion away from the battery. The first extension portion and screen mounting portion are arranged along a second direction, and the touch chip is disposed in the first extension portion. The first direction is the length direction of the electronic device, and the second direction is the width direction of the electronic device.
[0007] Generally, the normal operation of a first display screen requires the support of screen components, including touch chips, capacitors, and resistors. In related technologies, the screen components are located at the first connecting portion. Due to the thickness of the screen components, the first connecting portion cannot be stacked with the first battery. In this case, the first battery, the first connecting portion, and the screen mounting portion are arranged sequentially along the first direction. Assuming the total length space reserved for the first battery, the first connecting portion, and the screen mounting portion remains constant, and the length space occupied by the screen mounting portion remains fixed, the more length space the first connecting portion occupies, the smaller the dimension of the first battery along the first direction, and thus the smaller the battery capacity. The touch chip is the longest component among all screen components. Located between the first battery and the screen mounting portion, the sum of the length dimensions of the first connecting portion and the screen mounting portion along the first direction is approximately 22mm, resulting in the first connecting portion occupying too much length space. This, in turn, leads to a smaller battery capacity for the first battery.
[0008] In this application, by arranging the touch chip and screen bonding part along the second direction, the touch chip and screen bonding part reuse the space in the first direction, thereby reducing the length of the first connection part along the first direction. The saved space can be provided to the first battery, increasing the volume of the first battery, thereby increasing the battery capacity of the first battery and extending the battery life of the electronic device.
[0009] In some embodiments, the housing has a receiving cavity, and the mounting space and the receiving cavity are arranged along a second direction. There are two housings, namely a first housing and a second housing. The electronic device also includes a rotating mechanism, which is disposed between the first and second housings along the second direction, and the first and second housings are rotatably connected by the rotating mechanism. The receiving cavity is used to accommodate the rotating mechanism. A first display screen is disposed in the first housing. The battery, screen circuit board, screen mounting portion, and touch chip are all disposed within the mounting space of the first housing. The first display screen also includes a display area, which is connected to the screen mounting portion, and the display area and screen mounting portion are stacked along a third direction. Along the first direction, the central axis of the display area of the first display screen coincides with the central axis of the first housing. Along the second direction, the touch chip is located on the side of the screen mounting portion away from the rotating mechanism.
[0010] The mounting space and the receiving cavity are arranged along the second direction. A screen mounting portion is disposed in the mounting space, and a rotating mechanism is disposed within the receiving cavity. A portion of the first display screen is stacked on the screen mounting portion, and another portion of the first display screen is stacked on the rotating mechanism. Along the first direction, the central axis of the display area of the first display screen is located on the side of the mounting space closer to the rotating mechanism. Therefore, by placing the screen mounting portion on the side of the mounting space closer to the rotating mechanism, and placing the touch chip on the side of the screen mounting portion farther from the rotating mechanism, the distance between the central axis of the screen mounting portion and the central axis of the display area can be minimized. This allows the touch chip and the screen mounting portion to share the space in the first direction, while also ensuring a small eccentricity between the central axis of the screen mounting portion and the central axis of the display area, thus improving the reliability of the first display screen.
[0011] In some embodiments, the housing has a receiving cavity, and the mounting space and the receiving cavity are arranged along a second direction. There are two housings, namely a first housing and a second housing. The electronic device also includes a rotating mechanism, which is disposed between the first housing and the second housing along the second direction, and the first housing and the second housing are rotatably connected by the rotating mechanism. The receiving cavity is used to accommodate the rotating mechanism. A first display screen is disposed in the first housing. The battery, screen circuit board, screen mounting portion, and touch chip are all disposed within the mounting space of the first housing. The first display screen also includes a display area, which is connected to the screen mounting portion, and the display area and the screen mounting portion are stacked along a third direction. Along the first direction, the central axis of the display area of the first display screen coincides with the central axis of the first housing. Along the second direction, the touch chip is disposed between the screen mounting portion and the rotating mechanism.
[0012] This approach also allows the touch chip and the screen bonding part to share the space in the first direction, reducing the length of the first connection part along the first direction. The saved space can be provided to the first battery, increasing the volume and capacity of the first battery.
[0013] In some embodiments, the first connecting portion has a first pin, and the screen mounting portion has a second pin. The first pin and the second pin are fixedly connected to electrically connect the first connecting portion and the screen mounting portion.
[0014] Specifically, the portion of the first connecting part with a first pin is stacked on top of the portion of the screen bonding part with a second pin, such that the first pin and the second pin are stacked and in contact. Then, the stacked portion of the first connecting part and the screen bonding part is heated, causing the first pin and the second pin to mechanically connect, thereby achieving an electrical connection between the first connecting part and the screen bonding part. This method is easy to manufacture.
[0015] In some embodiments, the screen circuit board further includes a second extension portion, which is fixedly connected to the first connecting portion. The second extension portion and the first connecting portion are arranged along a first direction, and the second extension portion and the first extension portion are arranged along a second direction. Along a third direction, the second extension portion and the screen bonding portion are stacked. The third direction is the thickness direction of the electronic device. The touch chip and the first pin are electrically connected through internal wires of the second extension portion.
[0016] The second extension and the screen bonding section are stacked, which increases space utilization and improves the compactness of the electronic device structure. The touch chip and the first pin of the first connection section are electrically connected through the internal wiring of the second extension section. The connection pin of the touch chip is generally located on the side of the first extension section away from the first connection section. By setting the second extension section, the distance of the internal wiring between the touch chip and the first pin can be shortened, thereby reducing impedance.
[0017] In some embodiments, there are two housings, namely a first housing and a second housing. The electronic device also includes a rotating mechanism disposed between the first housing and the second housing along a second direction, and the first housing and the second housing are rotatably connected by the rotating mechanism. The electronic device also includes a first magnet and a second magnet. The first magnet is disposed within the mounting space of the first housing, and along a third direction, the first magnet and the touch chip are stacked. The second magnet is disposed within the mounting space of the second housing. The third direction is the thickness direction of the electronic device. When the electronic device is in a folded state, the first magnet and the second magnet attract each other.
[0018] The stacked arrangement of the first magnet and the touch chip can improve space utilization and enhance the structural compactness of electronic devices.
[0019] In some embodiments, the electronic device further includes a motor and a display driver chip, which are disposed within the mounting space. The display driver chip is disposed on the screen mounting portion. The motor and display driver chip are stacked along a third direction. This can improve space utilization and increase the structural compactness of the electronic device.
[0020] In some embodiments, the housing includes a mid-frame, and a mounting space is disposed within the mid-frame. A bracket is disposed within the mounting space and fixed to the mid-frame. Along a third direction, the screen mounting portion and the bracket are stacked, with the display driver chip disposed on the side of the screen mounting portion facing the bracket, and the motor fixed to the side of the bracket away from the screen mounting portion. The bracket supports the motor, which can increase the stability of the motor.
[0021] In some embodiments, a buffer is provided between the bracket and the display driver chip, with one side of the buffer contacting the display driver chip and the other side of the buffer contacting the bracket. The buffer can improve the drop reliability of the display driver chip.
[0022] In some embodiments, the cushioning element is made of foam or rubber.
[0023] In some embodiments, the electronic device further includes a touch protector, a voltage regulator, a filter capacitor, and a resistor. The touch protector, voltage regulator, filter capacitor, and resistor are all disposed at the first connection portion, and are arranged sequentially along the second direction.
[0024] In some embodiments, the sum of the lengths of the screen bonding portion and the first connecting portion along the first direction is less than 22 mm. In related technologies, the sum of the lengths of the screen bonding portion and the first connecting portion is 22 mm, which occupies too much space in the length direction, resulting in a small capacity of the first battery. In this application, however, the sum of the lengths of the screen bonding portion and the first connecting portion is less than 22 mm, reducing the space occupied and allowing the first battery to be designed to be larger, thereby increasing the capacity of the first battery.
[0025] In some embodiments, the sum of the lengths of the screen mounting portion and the first connecting portion is 15mm.
[0026] In some embodiments, a reinforcing sheet is provided on the side of the first extension away from the touch chip.
[0027] In some embodiments, the first extension is further provided with a protective cover, and the touch chip is located inside the cavity of the protective cover. Attached Figure Description

Detailed Implementation
[0056] The embodiments of this application are described below with reference to the accompanying drawings.
[0057] This application provides an electronic device, including but not limited to cellphones, candybar phones, notebook computers, tablet computers, personal digital assistants, wearable devices, and mobile devices. In some embodiments, a cellphone is used as an example for illustration.
[0058] Foldable phones include horizontal foldable phones and vertical foldable phones. Typically, foldable phones are rectangular in shape. A horizontal foldable phone folds along its width, reducing its width to half its unfolded size. A vertical foldable phone folds along its length, reducing its length to half its unfolded size.
[0059] Generally, horizontally foldable phones are mostly large-screen phones, also known as large-screen phones. Here, "large-screen" means that when horizontally foldable phones are unfolded, the screen area is approximately twice the size of a traditional smartphone screen. Vertically foldable phones are mostly small-screen phones, also known as small-screen phones. When vertically foldable phones are unfolded, the screen area is roughly the same as a traditional smartphone screen. Of course, the screen area of a horizontally foldable phone can also be the same as that of a traditional smartphone screen, or a multiple of it, such as 1.5 times, 2.1 times, or 2.5 times, etc. The screen area of a vertically foldable phone can also be 1.2 times, 1.5 times, or 2 times, etc., the size of a traditional smartphone screen. This embodiment uses a horizontally foldable phone as an example for explanation.
[0060] Please refer to Figures 1 and 2. This application provides an electronic device 1000. Figure 1 is a structural schematic diagram of the electronic device 1000 provided in the first state according to an embodiment of this application, and Figure 2 is a structural schematic diagram of the electronic device 1000 provided in the second state according to an embodiment of this application.
[0061] The electronic device 1000 shown in Figure 1 is in a folded state, and the electronic device 1000 shown in Figure 2 is in an unfolded state. The folding angle of the electronic device 1000 shown in Figure 1 is approximately 0 degrees. The unfolding angle of the electronic device 1000 shown in Figure 2 is approximately 180 degrees. For ease of description, the width direction of the electronic device 1000 is defined as the X-axis direction, the length direction of the electronic device 1000 is defined as the Y-axis direction, and the thickness direction of the electronic device 1000 is defined as the Z-axis direction. The X-axis, Y-axis, and Z-axis directions are mutually perpendicular. In the following text, the first direction refers to the Y-axis direction, the second direction refers to the X-axis direction, and the third direction refers to the Z-axis direction.
[0062] It should be noted that the directional terms such as "top," "bottom," "left," "right," "front," and "back" used in the description of the electronic device 1000 in this application embodiment are mainly based on the orientation of the electronic device 1000 shown in Figures 2 and 4. "Top" and "up" refer to the positive Z-axis direction, "bottom" and "down" refer to the negative Z-axis direction, "right" refers to the positive X-axis direction, "left" refers to the negative X-axis direction, "back" refers to the negative Y-axis direction, and "front" refers to the positive Y-axis direction. These terms do not constitute a limitation on the orientation of the electronic device 1000 in actual application scenarios.
[0063] Electronic device 1000 includes a main body 100 and a display screen, which is mounted on the main body 100. The display screen includes a display surface and a mounting surface, which are positioned opposite to each other, with the mounting surface facing the main body 100. The display surface is used to display text, images, and videos. There are two displays: a first display screen 200 and a second display screen 300. The first display screen 200 can be a rigid display screen. The second display screen 300 can be a flexible display screen. The size of the first display screen 200 is the same as that of a candybar mobile phone display screen. The second display screen 300 includes a first display section 310, a second display section 320, and a third display section 330. The third display section 330 is located between the first display section 310 and the second display section 320. Along the Z-axis, the first display screen 200 and the second display screen 300 are located on opposite sides of the main body 100. When the electronic device 1000 is in a folded state, the first display screen 200 is located on the outside and is visible; therefore, the first display screen 200 is also called the outer screen. The second display screen 300 is located on the inside and is not visible; therefore, the second display screen 300 is also called the inner screen.
[0064] Please refer to Figure 3, which is a schematic diagram of the split structure of the electronic device 1000 shown in Figure 2.
[0065] The main body 100 includes two housings 10 and a rotating mechanism 400. The two housings 10 are a first housing 10a and a second housing 10b, respectively. The rotating mechanism 400 is disposed between the first housing 10a and the second housing 10b and is connected to both housings 10a and 10b to achieve a rotatable connection between them. The first housing 10a and the second housing 10b can rotate relative to each other via the rotating mechanism 400, allowing the main body 100 to switch between a folded state and an unfolded state. When the second display screen 300 is installed on the main body 100, the first housing 10a carries the first display unit 310, the second housing 10b carries the second display unit 320, and the rotating mechanism 400 is positioned opposite to the third display unit 330. The first display screen 200 is installed on the side of the first housing 10a opposite to the first display unit 310.
[0066] Referring to Figures 2 and 3, the first housing 10a and the second housing 10b rotate relative to each other via a rotating mechanism 400. When the electronic device 1000 is in the unfolded state, the second display screen 300 has a large display area 220, enabling the electronic device 1000 to display and operate on a large screen, thus improving the user experience. Referring to Figure 1, when the electronic device 1000 is in the folded state, the second display screen 300 is positioned between the first housing 10a and the second housing 10b. The first housing 10a and the second housing 10b protect the display surface of the second display screen 300, greatly reducing the probability of damage to the second display screen 300, and also reducing the overall size for easier portability.
[0067] In this embodiment, the rotating mechanism 400 can be a hinge, connecting the first housing 10a and the second housing 10b. It functions as a rotating structure between the first housing 10a and the second housing 10b, enabling relative free rotation and relative folding of the two housings. Specifically, the rotating mechanism 400 includes two connected hinges arranged sequentially along the Y-axis, with one hinge connected to the first housing 10a and the other to the second housing 10b; alternatively, the rotating mechanism 400 includes a single hinge extending from one side of the phone to the other along the Y-axis. In other embodiments, the rotating mechanism 400 consists of two connected and relatively rotatable shafts, with one shaft rotatably connected to the first housing 10a and the other rotatably connected to the second housing 10b, enabling relative rotation of the first housing 10a and the second housing 10b. In other embodiments, the rotating mechanism 400 can also be a rotating structure of other types, as long as it can enable the first housing 10a and the second housing 10b to rotate freely relative to each other and fold relative to each other without damaging the second display screen 300.
[0068] Referring to Figure 4, which is a cross-sectional view along line AA in Figure 2, the housing 10 has a receiving cavity 11 and an installation space 12. The openings of the receiving cavity 11 and the installation space 12 are located on opposite sides of the housing 10 along the Z-axis. Specifically, the housing 10 includes a middle frame 13, which includes a side frame 14 and a middle plate 15. The side frame 14 surrounds the outer periphery of the middle plate 15, and the side frame 14 and the middle plate 15 are fixedly connected. The receiving cavity 11 is formed by bending the middle plate 15, and the installation space 12 is formed by enclosing the middle plate 15 and the side frame 14.
[0069] When the electronic device 1000 is in the unfolded state, the receiving cavity 11 of the first housing 10a and the receiving cavity 11 of the second housing 10b are opposite to each other and connected along the X-axis. A portion of the rotating mechanism 400 is located within the receiving cavity 11 of the first housing 10a, and another portion of the rotating mechanism 400 is located within the receiving cavity 11 of the second housing 10b. The first display screen 200 is fixed to the first housing 10a and closes the opening of the mounting space 12 of the first housing 10a. The mounting opening of the second housing 10b is closed using a rear cover 16.
[0070] Referring to Figure 5, which is a schematic diagram of the internal structure of the electronic device 1000 provided in an embodiment of this application, the mounting space 12 of the housing 10 is used to mount functional devices 20, which may include batteries, circuit boards, cameras 27 (CMA), and card slots 28, etc. The batteries include a first battery 21 and a second battery 22, and the circuit boards include a first circuit board 23, a second circuit board 24, a third circuit board 25, and a fourth circuit board 26. The first circuit board 23, the second circuit board 24, the third circuit board 25, and the fourth circuit board 26 can all be printed circuit boards (PCBs).
[0071] The first circuit board 23, the second circuit board 24, and the first battery 21 are all installed in the mounting space 12 of the first housing 10a, and the first circuit board 23, the first battery 21, and the second circuit board 24 are arranged sequentially along the first direction. A speaker or the like can be installed on the second circuit board 24.
[0072] The third circuit board 25, the fourth circuit board 26, and the second battery 22 are all installed within the mounting space 12 of the second housing 10b, and are arranged sequentially along the first direction. It can be understood that the first circuit board 23 can be a small board of the first housing 10a, the second circuit board 24 can be the main board of the first housing 10a, the third circuit board 25 can be the main board of the second housing 10b, and the fourth circuit board 26 can be a small board of the second housing 10b. The first circuit board 23 and the second circuit board 24 can be electrically connected via flexible circuit boards, the first circuit board 23 and the third circuit board 25 can be electrically connected via a through-axis flexible circuit board, and the third circuit board 25 and the fourth circuit board 26 can be electrically connected via flexible circuit boards.
[0073] There can be multiple cameras 27, for example, three cameras 27, with one camera 27 installed in the mounting space 12 of the first housing 10a and the other two cameras 27 installed in the mounting space 12 of the second housing 10b. The cameras 27 can be front-facing cameras 27 or rear-facing cameras 27.
[0074] Card slot 28 is used to install a subscriber identity module (SIM) card. Specifically, a SIM card can be inserted into card slot 28, and a SIM card can also be removed from card slot 28 to achieve contact and separation between the SIM card and the foldable electronic device 10001000. Nano SIM cards, Micro SIM cards, and other SIM cards can be installed in card slot 28. Multiple SIM cards can be inserted into the same card slot 28 simultaneously; the multiple cards can be of the same or different types. Card slot 28 can be disposed within the mounting space 12 of the second housing 10b.
[0075] When the first display screen 200 is installed in the first housing 10a, the screen mounting portion 210 of the first display screen 200 is located within the mounting space 12 of the first housing 10a, and along a third direction, the screen mounting portion 210 and the second circuit board 24 are stacked. The electronic device 1000 also includes a screen circuit board 30, which is a flexible printed circuit (FPC). The screen circuit board 30 is stacked on the first battery 21, and both ends of the screen circuit board 30 are respectively connected to the first circuit board 23 and the screen mounting portion 210, so that the screen mounting portion 210 can be electrically connected to the first circuit board 23 through the screen circuit board 30.
[0076] Referring to Figure 6, which is a schematic diagram of the structure of the first display screen 200 of the electronic device 1000 provided in this application embodiment, the first display screen 200 includes a display (active area, AA) area and a non-display area 230 according to its function. The display area 220 is used to display images, text, videos, etc. The non-display area 230 cannot display content and surrounds the outer periphery of the display area 220. The non-display area 230 includes an arcuate portion 231, a curved portion 232, and a screen mounting portion 210. The arcuate portion 231 is connected to the outer periphery of the display area 220, the curved portion 232 is connected to the outer periphery of the arcuate portion 231, and the screen mounting portion 210 is connected to the outer periphery of the curved portion 232. The arc-shaped portion 231 makes the two sides of the first display screen 200 arc-shaped along the Y-axis, which can increase the display area ratio of the first display screen 200. The bending portion 232 can be bent relative to the display area 220, so that the screen bonding portion 210 is bent to the backlight side facing the display area 220, so as to facilitate the encapsulation of the first display screen 200.
[0077] Referring to Figure 7, which is a cross-sectional view along line BB in Figure 6, the first display screen 200, when divided by layer structure, includes a cover plate 233, a polarizer 234, a display layer 235, and a flexible layer 236. Along the Z-axis, the cover plate 233, polarizer 234, display layer 235, and flexible layer 236 are sequentially stacked and fixed, with the light-emitting side of the display layer 235 facing the polarizer 234. The cover plate 233 and polarizer 234 can be bonded together using adhesive. The cover plate 233 can be a transparent glass plate. The display layer 235 includes a pixel array and a display driving circuit. The pixel array includes multiple pixel units, and the display driving circuit controls the operation of the pixel array to achieve the display function. The flexible layer 236 can be a bendable plate-like structure, and can be made of at least one of polyethylene terephthalate (PET) or polyimide (PI). The cover plate 233, polarizer 234, pixel array of display layer 235, part of display driving circuit of display layer 235, and part of flexible layer 236 are located in area AA, while another part of display driving circuit of display layer 235 and another part of flexible layer 236 are located in non-display area 230. It can be understood that the cover plate 233 is arc-shaped on both sides along the Y-axis direction to make the appearance of the first display screen 200 arc-shaped.
[0078] Referring to Figure 8, which is a schematic diagram of the packaging structure of the first display screen 200 of the electronic device 1000 provided in this application embodiment, the first display screen 200 is packaged using a COP (chip on panel) packaging process. Specifically, during packaging, the bending portion 232 bends relative to the display area 220, causing the screen bonding portion 210 to bend towards the backlight side of the display area 220, and then the screen bonding portion 210 and the screen circuit board 30 are bonded together. A display driver chip 211 (display driver integrated circuit, DDIC) is provided on the side of the screen bonding portion 210 away from the display area 220. The screen bonding portion 210 and the display driver chip 211 are electrically connected. The display driver chip 211 can be directly connected to the screen bonding portion 210. The display driver chip 211 can provide display driving signals, and the display driving circuit can drive the pixel array to work based on the display driving signals, so that the first display screen 200 can realize the display function.
[0079] After the screen bonding part 210 and the screen circuit board 30 are bonded, the screen device 40 on the screen circuit board 30 can be electrically connected to the screen bonding part 210. The screen device 40 is specifically disposed on the side of the screen circuit board 30 facing away from the display area 220 of the first display screen 200. The screen device 40 includes a touch panel integrated circuit (TPIC) chip 41 and a protection device 42. The protection device 42 includes a touch protector, a voltage regulator capacitor, a filter capacitor, and a resistor, etc. The touch panel integrated circuit (TPIC) chip 41 receives and processes touch signals and transmits the touch signals to the display driver chip 211, so that the display driver chip 211 drives the pixel array to perform corresponding display. The protection device 42 protects the touch panel integrated circuit (TPIC) chip 41 and performs voltage regulation and filtering, etc.
[0080] Referring to Figure 9, which is a schematic diagram of the arrangement of the touch chip 41 and the screen bonding portion 210 along a first direction in the electronic device 1000 provided in this application embodiment, in some embodiments, the screen circuit board 30 includes a first connecting portion 31, a second connecting portion 32, and a third connecting portion 33, which are sequentially connected along the first direction. The side of the first connecting portion 31 away from the second connecting portion 32 is connected to the screen bonding portion 210, that is, the first connecting portion 31 and the screen bonding portion 210 are bonded. The second connecting portion 32 is stacked on the first battery 21, and the side of the third connecting portion 33 away from the second connecting portion 32 is connected to the first circuit board 23.
[0081] The screen device 40 is disposed on the first connecting portion 31. Because the screen device 40 is relatively thick, the first connecting portion 31 cannot be stacked with the first battery 21; that is, the first battery 21 and the first connecting portion 31 need to be completely offset along the Y-axis. At this time, the first battery 21, the first connecting portion 31, and the screen mounting portion 210 are arranged sequentially along the first direction, with all screen devices 40 located between the first battery 21 and the screen mounting portion 210 along the first direction. Under the premise that the total length space reserved for the first battery 21, the first connecting portion 31, and the screen mounting portion 210 remains unchanged, and the length space occupied by the screen mounting portion 210 remains fixed, the more length space occupied by the first connecting portion 31, the smaller the size of the first battery 21 along the Y-axis, and thus the smaller the battery capacity of the first battery 21. Conversely, the less length space occupied by the first connecting portion 31, the larger the size of the first battery 21 along the Y-axis, and thus the larger the battery capacity of the first battery 21. However, in some embodiments, the touch chip 41 is generally a rectangular piece of about 5mm*5.4mm, making it the longest device among all screen devices 40. The touch chip 41 is located between the first battery 21 and the screen bonding portion 210. The sum of the lengths F0 of the first connecting portion 31 and the screen bonding portion 210 along the first direction is approximately 22mm, resulting in the first connecting portion 31 occupying too much length space. Furthermore, a portion of the protective device 42 is arranged along the first direction, also contributing to the excessive length space occupied by the first connecting portion 31. This, in turn, results in a smaller battery capacity for the first battery 21.
[0082] To address the aforementioned issues, in some embodiments, referring to Figures 10 and 11, Figure 10 is a schematic diagram showing the arrangement of the touch chip 41 and screen bonding portion 210 along a second direction in the electronic device 1000 provided in this application embodiment, and Figure 11 is a partial schematic diagram showing the arrangement of the touch chip 41 and screen bonding portion 210 along the second direction in the electronic device 1000 provided in this application embodiment. The screen circuit board 30 includes a first connecting portion 31, a second connecting portion 32, a third connecting portion 33, and a first extension portion 34. Along the first direction, the first extension portion 34, the first connecting portion 31, the second connecting portion 32, and the third connecting portion 33 are connected sequentially, that is, the first extension portion 34 is connected to the side of the first connecting portion 31 away from the second connecting portion 32. Furthermore, along the second direction, the width of the first extension portion 34 is smaller than the width of the first connecting portion 31. Along the second direction, the first extension 34 and the screen bonding part 210 are arranged along the second direction, and the touch chip 41 is disposed on the first extension 34. That is, the touch chip 41 and the screen bonding part 210 are arranged along the second direction, which is perpendicular to the first direction and is the X-axis direction.
[0083] It can be understood that "touch chip 41 is located in the first extension portion 34" means that at least part of the touch chip 41 is located in the first extension portion 34. Specifically, the touch chip 41 may be partially located in the first extension portion 34 and partially located in the first connection portion 31. Alternatively, the touch chip 41 may be entirely located in the first extension portion 34.
[0084] The protection device 42 is disposed on the first connecting part 31, and the protection device 42 is arranged sequentially along the second direction. The touch protector, voltage regulator, filter capacitor, and resistor coincide along the central axis of the second direction. In this way, the sum of the lengths of the first connecting part 31 and the screen bonding part 210 along the first direction is less than 22mm. More specifically, the sum of the lengths of the first connecting part 31 and the screen bonding part 210 along the first direction can be 14.5mm, 14.7mm, 14.9mm, 15mm, 15.2mm, 15.4mm, 15.6mm, 15.8mm, 16mm, 16.5mm, 17mm, 17.5mm, 18mm, 18.5mm, 19mm, 19.5mm, 20mm, 20.5mm, 20.7mm, 21mm, 21.5mm, or 21.6mm, etc. In one specific embodiment, the sum of the lengths F1 of the first connecting portion 31 and the screen binding portion 210 along the first direction is 15mm. Compared with the solution in the above embodiment, the sum of the lengths of the first connecting portion 31 and the screen binding portion 210 is reduced by 7mm.
[0085] By arranging the touch chip 41 and the screen bonding part 210 along the second direction, the touch chip 41 and the screen bonding part 210 reuse the space in the Y-axis direction, thereby reducing the length of the first connecting part 31 in the Y-axis direction. The saved space can be provided to the first battery 21, increasing the volume of the first battery 21 and thus increasing its battery capacity, extending the battery life of the electronic device 1000. In addition, the protection device 42 is arranged along the second direction, further reducing the length of the first connecting part 31 in the Y-axis direction. The saved space can also be provided to the first battery 21, further increasing the volume of the first battery 21 and its battery capacity.
[0086] In some embodiments, referring to FIG12, FIG12 is a schematic diagram of the distribution structure of the central axis of the screen mounting portion 210 and the display area 220 in the electronic device 1000 provided in this application embodiment. The touch chip 41 and the screen mounting portion 210 are arranged along the second direction, and the touch chip 41 is located on the side of the screen mounting portion 210 away from the rotating mechanism 400. As a result, along the Y-axis direction, the distance between the central axis H1 of the screen mounting portion 210 and the central axis H0 of the display area 220 of the first display screen 200 is reduced or even disappears. It can be understood that the disappearance of the distance between the central axis H1 of the screen mounting portion 210 and the central axis H0 of the display area 220 of the first display screen 200 means that the central axis H1 of the screen mounting portion 210 and the central axis H0 of the display area 220 of the first display screen 200 coincide, and this coincidence includes processing and assembly errors. This can further avoid display abnormalities of the first display screen 200. The specific reasons are as follows: The receiving cavity 11 of the first housing 10a needs to accommodate the rotating mechanism 400, and the thickness of the receiving cavity 11 is required to be relatively high. Therefore, there is no extra space on the back of the receiving cavity 11 to accommodate other components. That is, the mounting space 12 cannot extend to the back of the receiving cavity 11. The mounting space 12 and the receiving cavity 11 are arranged along the X-axis.
[0087] Because, along the X-axis, the width of the mounting space 12 is greater than the width of the receiving cavity 11, and the width of the first display screen 200 is the sum of the widths of the mounting space 12 and the receiving cavity 11, the central axis H0 of the display area 220 and the central axis of the mounting space 12 are offset from each other along the Y-axis. Because the screen mounting part 210 is disposed in the mounting space 12, and the rotating mechanism 400 is disposed within the receiving cavity 11, in order to minimize the distance between the central axis H1 of the screen mounting part 210 and the central axis H0 of the display area 220, the screen mounting part 210 needs to be disposed on the side of the mounting space 12 closer to the rotating mechanism 400, while the touch chip 41 is disposed on the side of the screen mounting part 210 away from the rotating mechanism 400. Referring to FIG13, FIG13 is a schematic diagram of the distribution structure of the central axis of the screen mounting part 210 and the display area 220 in an electronic device 1000 provided in another embodiment of this application. Compared to the arrangement in Figure 13 where the touch chip 41 is positioned between the screen mounting portion 210 and the rotation mechanism 400, the solution shown in Figure 12 significantly reduces the gap between the central axis H0 of the display area 220 and the central axis H1 of the screen mounting portion 210. This allows the touch chip 41 and the screen mounting portion 210 to share space along the Y-axis while ensuring a smaller eccentricity between the central axis H1 of the screen mounting portion 210 and the central axis H0 of the display area 220, thus improving the reliability of the first display screen 200.
[0088] In other embodiments, referring to Figures 14 and 15, Figure 14 is a schematic diagram of the arrangement of the touch chip 41 and the screen bonding portion 210 along the second direction in another electronic device 1000 provided in this application embodiment, and Figure 15 is a partial schematic diagram of the arrangement of the touch chip 41 and the screen bonding portion 210 along the second direction in another electronic device 1000 provided in this application embodiment. Along the Y-axis direction, the touch chip 41 can be disposed between the top of the screen panel and the rotating mechanism 400. This scheme also allows the touch chip 41 and the screen bonding portion 210 to share the space in the Y-axis direction, reducing the length of the first connecting portion 31 along the Y-axis direction. The saved space can be provided to the first battery 21, increasing the volume and capacity of the first battery 21.
[0089] In some embodiments, referring to FIG16, FIG16 is a schematic diagram of the bonding structure of the screen bonding portion 210 and the first extension portion 34 in the electronic device 1000 provided in this application embodiment. The first connecting portion 31 of the screen circuit board 30 and the screen bonding portion 210 of the first display screen 200 are generally bonded using pins. Specifically, the first connecting portion 31 is provided with a first pin 35, and the screen bonding portion 210 is provided with a second pin 212. The portion of the first connecting portion 31 with the first pin 35 is stacked on the portion of the screen bonding portion 210 with the second pin 212, so that the first pin 35 and the second pin 212 are stacked and in contact. Then, the stacked portion of the first connecting portion 31 and the screen bonding portion 210 is heated, so that the first pin 35 and the second pin 212 are mechanically connected, thereby realizing the electrical connection between the first connecting portion 31 and the screen bonding portion 210. Typically, there are multiple first pins 35 and second pins 212, and in order to increase the reliability of the electrical connection between the screen circuit board 30 and the screen bonding portion 210, some redundant pins are also provided.
[0090] It is understandable that, along the third direction, the portion of the first connecting part 31 with the first pin 35 overlaps with the portion of the screen bonding part 210 with the second pin 212. Therefore, when calculating the sum of the lengths of the first connecting part 31 and the screen bonding part 210 along the first direction, only one of the overlapping portions needs to be calculated. For example, only the portion of the first connecting part 31 with the first pin 35 can be calculated, while the portion of the screen bonding part 210 with the second pin 212 is not included. Alternatively, only the portion of the screen bonding part 210 with the second pin 212 can be calculated, while the portion of the first connecting part 31 with the first pin 35 is not calculated. This is to avoid double counting and resulting in errors in the calculated length.
[0091] Because the touch chip 41 and the screen bonding portion 210 are arranged along the second direction, compared to the above embodiment, the size of the portion where the first connecting portion 31 and the screen bonding portion 210 are connected along the second direction is reduced, that is, the width of the overlapping portion of the first connecting portion 31 and the screen bonding portion 210 is reduced. This results in a reduction in the space available for the first pin 35 and the second pin 212. To ensure a reliable electrical connection between the first connecting portion 31 and the screen bonding portion 210, the pins can be modified using any of the following three methods: First, remove redundant first pins 35 and second pins 212. Second, reduce the number of first pins 35 and second pins 212 and increase the width of the remaining first pins 35 and second pins 212. Third, reduce the gap between two adjacent first pins 35 and the gap between two adjacent second pins 212.
[0092] In some embodiments, referring to FIG17, FIG17 is a schematic diagram of the structure of an electronic device 1000 provided in this application, wherein a screen circuit board 30 is provided with a second extension 36. The touch chip 41 needs to be electrically connected to the first pin 35 of the screen circuit board 30 through internal traces 37. To facilitate the electrical connection between the touch chip 41 and the first pin 35, the screen circuit board 30 further includes a second extension 36. The second extension 36 is connected to the side of the first connecting portion 31 away from the second connecting portion 32. The first extension 34 and the second extension 36 are arranged along the X-axis direction, and along the Y-axis direction, the length of the second extension 36 is greater than the length of the first extension 34. Along the Z-axis direction, the second extension 36 and the screen bonding portion 210 are stacked, which can increase space utilization and improve the structural compactness of the electronic device 1000. The touch chip 41 and the first pin 35 of the first connecting portion 31 can be electrically connected through the internal traces 37 of the second extension 36. The connection pins of the touch chip 41 are generally located on the side of the first extension 34 away from the first connection 31. By providing the second extension 36, the distance of the internal trace 37 between the touch chip 41 and the first pin 35 can be shortened, thereby reducing the impedance.
[0093] Referring to Figure 18, which is a schematic diagram of the screen circuit board 30 in the electronic device 1000 provided in this application embodiment without the second extension portion 36, the touch chip 41 and the first pin 35 of the first connection portion 31 are electrically connected through the internal trace 37 of the first connection portion 31. This results in a larger width for the first connection portion 31 and a longer length for the internal trace 37 between the touch chip 41 and the first pin 35, leading to higher impedance. Compared to the solution shown in Figure 18, the solution shown in Figure 17, by providing the second extension portion 36, can reduce impedance and save space. Furthermore, the saved width in the X-axis direction can be compensated for by the screen bonding portion 210 or by the arc-shaped portion 231 of the first display screen 200.
[0094] In some embodiments, referring to FIG19, FIG19 is a structural schematic diagram of an electronic device 1000 provided in this application, in which a first magnet 50 and a second magnet 51 are disposed. The electronic device 1000 also includes multiple magnets, which may include the first magnet 50 and the second magnet 51. The first magnet 50 is disposed within the mounting space 12 of the first housing 10a, and the second magnet 51 is disposed within the mounting space 12 of the second housing 10b. When the electronic device 1000 is in a folded state, the first magnet 50 and the second magnet 51 attract each other to prevent the first housing 10a and the second housing 10b from opening, ensuring reliable folding of the electronic device 1000. Multiple first magnets 50 and second magnets 51 can be used. For example, one first magnet 50 can be disposed at each of the four corner areas of the mounting space 12 of the first housing 10a, and one second magnet 51 can be disposed at each of the two corner areas of the mounting space 12 of the second housing 10b. When the electronic device 1000 is in a folded state, two first magnets 50 and two second magnets 51 attract each other to increase the stability of the electronic device 1000 in the folded state.
[0095] Specifically, referring to Figures 20, 21, and 22, Figure 20 is a partial structural diagram of the electronic device 1000 provided in this embodiment of the application; Figure 21 is a structural diagram of the touch chip 41 and the first magnet 50 stacked in the electronic device 1000 provided in this embodiment of the application; and Figure 22 is a partial structural diagram of the electronic device 1000 provided in this embodiment of the application. There is also space below the touch chip 41, which can be used to accommodate the first magnet 50. That is, along the Z-axis direction, a first magnet 50 and a touch chip 41 can be stacked, meaning that the orthographic projection of the first magnet 50 onto the bottom wall of the mounting space 12 and the projection of the touch chip 41 onto the bottom wall of the mounting space 12 at least partially overlap. This increases space utilization and improves the structural compactness of the electronic device 1000.
[0096] It is understood that a reinforcing sheet 60 is provided on the side of the first extension 34 facing away from the touch chip 41, that is, on the side of the first extension 34 facing the backlight side of the display area 220. The reinforcing sheet 60 can be made of steel, and along the Z-axis direction, the orthographic projection of the reinforcing sheet 60 on the first extension 34 coincides with the orthographic projection of the touch chip 41 on the first extension 34. The reinforcing sheet 60 is used to support the touch chip 41. In addition, the first extension 34 is also provided with a protective cover 70, and the touch chip 41 is located in the cavity of the protective cover 70. The protective cover 70 is used to protect the touch chip 41.
[0097] A protective element 80 is also provided between the touch chip 41 and the inner wall of the mounting space 12. The protective element 80 can be foam.
[0098] In some embodiments, referring to FIG23, FIG23 is a partial structural schematic diagram of another part of the electronic device 1000 provided in this application embodiment. Along the Z-axis direction, there is also space below the display driver chip 211, which can be used to accommodate the motor 29. The motor 29 can generate vibration prompts. The motor 29 can be used for incoming call vibration prompts or for touch vibration feedback. For example, touch operations applied to different applications (such as taking pictures, playing audio, etc.) can correspond to different vibration feedback effects. Touch operations applied to different areas of the display screen can also correspond to different vibration feedback effects for the motor 29. Different application scenarios (such as time reminders, receiving messages, alarm clocks, games, etc.) can also correspond to different vibration feedback effects. The touch vibration feedback effect can also be customized.
[0099] Specifically, referring to Figures 24, 25, and 26, Figure 24 is a partial structural diagram of the electronic device 1000 provided in this embodiment of the application; Figure 25 is yet another partial structural diagram of the electronic device 1000 provided in this embodiment of the application; and Figure 26 is a structural diagram showing the stacked display driver chip 211 and motor 29 of the electronic device 1000 provided in this embodiment of the application. Figure 25 is a view of Figure 22 after removing the first connecting portion 31, the first extension portion 34, and the screen bonding portion 210. Figure 25 is a view of Figure 23 after adding the bracket 17, the buffer 90, the touch chip 41, and the protective device 42. A bracket 17 is provided in the mounting space 12. The bracket 17 is fixed to the frame 14. The bracket 17 can be fixed to the frame 14 by fasteners such as screws or bolts, or by welding. Along the Z-axis direction, the screen bonding portion 210, the bracket 17, and the second circuit board 24 are stacked sequentially. The display driver chip 211 is connected to the side of the screen circuit board 30 facing the bracket 17. The second circuit board 24 has clearance holes. The motor 29 is fixed to the side of the bracket 17 away from the screen mounting part 210. The motor 29 passes through the clearance holes and even the side of the second circuit board 24 away from the bracket 17. The motor 29 is electrically connected to the second circuit board 24. Along the Z-axis, the orthographic projection of the display driver chip 211 on the bottom wall of the mounting space 12 and the orthographic projection of the motor 29 on the bottom wall of the mounting space 12 at least partially overlap. That is, the display driver chip 211, the buffer 90, the bracket 17, and the motor 29 are stacked sequentially along the Z-axis. This increases space utilization and improves the structural compactness of the electronic device 1000. A buffer 90 is provided between the display driver chip 211 and the bracket 17. The buffer 90 can be made of foam or rubber. One side of the buffer 90 contacts the display driver chip 211, and the other side contacts the motor 29 to improve the drop reliability of the display driver chip 211.
