Description

Technical Field

[0001] This application relates to the field of communication equipment technology, and more particularly to an electronic device. Background Technology

[0002] With the development of technology, mobile phones, tablets, laptops, and other electronic devices have become commonly used. To increase the size of the display screen, electronic devices can be foldable, consisting of a main screen and a secondary screen. The main screen can be a flexible screen that can be folded. When the electronic device is folded, the main screen, acting as the inner screen, is folded, and the user can operate it through the secondary screen. When the electronic device is unfolded, the main screen is unfolded, and the user can operate it through the main screen. However, when the electronic device is unfolded, the effective display area of ​​the main screen is relatively small, resulting in a poor user experience. Summary of the Invention

[0003] This application provides an electronic device for increasing the effective viewable area of ​​the electronic device screen.

[0004] This application provides an electronic device, the electronic device comprising:

[0005] First shell;

[0006] A second housing, wherein the first housing is connected to the second housing via a folding device;

[0007] A first screen covers one side of the first housing along the thickness direction of the electronic device;

[0008] The second screen is located on the side of the first housing away from the first screen along the thickness direction of the electronic device, and the second screen covers the first housing and the second housing;

[0009] A telephoto module is disposed on the side of the second housing away from the second screen along the thickness direction of the electronic device, and the telephoto module extends along the width direction of the electronic device;

[0010] Wherein, the width of the first screen is x1, the length is y1, and 2 / 3≤x1 / y1≤8 / 9; the width of the second screen is x2, the length is y2, and 4 / 3≤x2 / y2≤16 / 9; the width of the first housing is m; and the width of the telephoto module is n, and n≥40%m.

[0011] This design allows the width-to-length ratio of the second screen in its unfolded state to closely approximate the aspect ratio of media such as videos and images (typically 4:3). Therefore, during display, videos and images can be better displayed on the second screen, increasing its effective viewable area and utilization rate. Compared to related technologies where the width-to-length ratio of the unfolded second screen is 18:20, the solution provided in this application has a width-to-length ratio closer to that of video and image media. This reduces the possibility of "black borders" appearing on both sides of the second screen, thus improving the user experience. Electronic devices are typically designed with a casing size close to the screen size to achieve a full-screen design, reducing black borders and improving the user experience. Furthermore, when 2 / 3 ≤ x1 / y1 ≤ 8 / 9 and 4 / 3 ≤ x2 / y2 ≤ 16 / 9, the width-to-length ratio of the electronic device in its folded state can be increased. For the same length, the electronic device provided in this embodiment has a larger width dimension. Therefore, a telephoto module 21 with a larger width dimension can be used. The width of the first housing is m, and the width of the telephoto module is n, where n ≥ 40% m, meaning the width of the telephoto module is not less than 40% of the width of the first housing. This makes the size of the telephoto module on the electronic device relatively large, thereby improving the performance of the telephoto module, including but not limited to increasing the equivalent focal length of the telephoto module and increasing the optical zoom ratio, thus improving the shooting quality of the electronic device.

[0012] In one possible implementation, the optical zoom ratio of the telephoto module is a, and the equivalent focal length of the telephoto module is b.

[0013] 3 ≤ a ≤ 10, and / or, 70 mm ≤ b ≤ 240 mm.

[0014] Because of the increased size of the telephoto module, its optical zoom ratio and equivalent focal length can also be increased. A higher optical zoom ratio allows electronic devices to capture distant objects with better image quality. A longer equivalent focal length means stronger magnification, enabling the capture of distant objects with good sharpness. During shooting, a longer focal length results in better background blur, thus better highlighting the subject. By increasing the optical zoom ratio and equivalent focal length, the telephoto module can be adapted to different shooting scenarios.

[0015] In one possible implementation, the diagonal size of the sensor in the telephoto module is 1 / 1.4 inch to 1 inch.

[0016] The solution provided in this application embodiment can improve the performance of the telephoto module by increasing the size of the sensor. Increasing the sensor size effectively improves the light intake and image quality of the telephoto module, especially enhancing shooting quality in low-light environments. Simultaneously, a larger sensor has better resolution, maintaining high image quality during zooming and facilitating better zoom performance.

[0017] In one possible implementation, along the width direction of the electronic device, the size of the telephoto module is n≤80%m, and 40 mm≤n≤80 mm.

[0018] When the size of the telephoto module is less than 40%m, it is too small, limiting its overall performance and affecting image quality. When the size of the telephoto module is greater than 80%m, it is too large, affecting the layout of the circuit board, mid-frame, and other structures. This necessitates a readjustment of the internal structure of the electronic device, and the insufficient mounting space for the circuit board and mid-frame can easily affect the stability of electrical connections to other components and the structural strength of the electronic device, making it prone to damage. Therefore, the solution provided in this application allows the telephoto module size to be between 40%m and 80%m. This maximizes the telephoto module's size to improve its performance while minimizing its impact on other components, better meeting practical usage requirements.

[0019] In one possible implementation, the electronic device has a first state and a second state. In the first state, the first housing and the second housing are stacked along the thickness direction of the electronic device. In the second state, the first housing and the second housing are distributed along the width direction of the electronic device.

[0020] When the electronic device is in the first state, the thickness of the electronic device is 8 mm to 12 mm;

[0021] When the electronic device is in the second state, the thickness of the electronic device is 4 mm to 6 mm.

[0022] The electronic device provided in this application embodiment has a relatively small thickness in both the folded and unfolded states. In the solution provided in this application embodiment, the ratio of the width to the length of the electronic device is increased. Therefore, when the length of the electronic device remains unchanged, by reducing the thickness of the electronic device, the possibility that the increased width of the electronic device will make it inconvenient to pick up can be reduced to a certain extent, thereby making it easier for users to pick up the electronic device and improving the user experience.

[0023] In one possible implementation, the first screen has a first edge along the width direction of the electronic device, the first housing has a second edge along the width direction of the electronic device, and the minimum distance between the first edge and the second edge along the width direction of the electronic device is c, where 0.8 mm ≤ c ≤ 3 mm.

[0024] When the distance between the first and second edges is less than 0.8 mm, the space reserved at the edge of the first housing is too small, which can easily lead to a reduction in the width of the middle frame. This not only reduces the structural strength of the middle frame but also increases the difficulty of placing components on it. When the distance between the first and second edges is greater than 3 mm, the distance is too large, resulting in a large black border around the first screen. This design also occupies space on the first screen, making it smaller and affecting the user experience. Therefore, the distance between the first and second edges is typically between 0.8 mm and 3 mm. This design meets the structural requirements of electronic devices, reduces the size of the black border, and improves the user experience.

[0025] In one possible implementation, along the width direction of the electronic device, the second screen has a third edge, the first housing has a fourth edge, the second housing has a fifth edge, the spacing between the third edge and the fourth edge, and the distance between the third edge and the fifth edge are both d, and 0.8 mm ≤ d ≤ 4 mm.

[0026] When the distance between the third edge and the fourth and fifth edges is less than 0.8 mm, the space reserved at the edge of the second screen is too small. This affects the arrangement space of the electronic device's frame and other electronic components, and the limited space for the second screen's movement can easily lead to creases during use. When the distance between the third edge and the fourth and fifth edges is greater than 4 mm, the distance between the third and fourth edges is too large, resulting in a large black border during use, reducing the screen-to-body ratio of the second screen and affecting the user experience. Therefore, in the solution provided in this application embodiment, the distance between the third edge and the fourth and fifth edges is between 0.8 mm and 4 mm, which meets the usage requirements while reducing the size of the black border, making it more in line with actual usage needs.

[0027] In one possible implementation, the electronic device includes a first camera module disposed in the second housing. The first camera module includes a main camera module, which is located on one side of the telephoto module along the width direction of the second housing.

[0028] By arranging the telephoto module and the main camera module along the width of the electronic device, the space occupied by the telephoto module and the first camera module in the length direction of the electronic device can be reduced, thereby reserving more space for arranging structures such as batteries, so as to improve the battery life and other performance of the electronic device.

[0029] In one possible implementation, the first camera module further includes a wide-angle module, the main camera module and the wide-angle module are located on one side of the telephoto module along the width direction of the second housing, and the main camera module and the wide-angle module are arranged sequentially along the length direction of the second housing.

[0030] By setting a wide-angle module, you can have a wider field of view when shooting, thus capturing more content and better capturing more details. Wide-angle modules are suitable for various shooting scenarios and can reduce the impact of camera shake on image quality.

[0031] In one possible implementation, the first camera module further includes a wide-angle module and a multispectral module. The main camera module is located on one side of the telephoto module along the width direction of the second housing, and the wide-angle module and the multispectral module are located on the other side of the telephoto module along the width direction of the second housing. The wide-angle module and the multispectral module are arranged sequentially along the length direction of the second housing.

[0032] Multispectral modules can be used to improve the accuracy of color reproduction, improve color cast, thereby enhancing shooting effects and improving shooting quality.

[0033] In one possible implementation, the electronic device includes a circuit board having a recessed portion along the thickness direction of the electronic device, and a portion of the telephoto module is located within the recessed portion.

[0034] A portion of the telephoto module is located within the recessed area so that the telephoto module can be embedded in the circuit board. The circuit board and the telephoto module overlap in some areas in the thickness direction. Compared to the telephoto module and the circuit board being distributed along the thickness direction of the electronic device, this can reduce the thickness of the electronic device, which is beneficial for the design of thinner and lighter electronic devices.

[0035] This application provides an electronic device comprising a first housing, a second housing, a first screen, a second screen, and a telephoto module. The first and second housings are connected by a folding device, allowing them to rotate relative to each other. The first and second screens are located on opposite sides of the first housing, with the second screen covering both housings. The telephoto module is located on the side of the second housing furthest from the second screen. The first screen has a width of x1 and a length of y1, where 2 / 3 ≤ x1 / y1 ≤ 8 / 9. The second screen has a width of x2 and a length of y2, where 4 / 3 ≤ x2 / y2 ≤ 16 / 9. The first housing has a width of m, and the telephoto module has a width of n, where n ≥ 40%m. This design increases the effective viewing area of ​​the second screen and enlarges the size of the telephoto module, thereby improving the shooting performance of the electronic device.

Detailed Implementation

[0056] This application provides an electronic device, including, for example, a mobile phone, tablet computer, personal digital assistant (PDA), laptop computer, in-vehicle computer, foldable display device, foldable display screen, wearable device, and any other device with foldable screen functionality. This application does not impose any special limitations on the specific form of the above-mentioned electronic device. For ease of explanation, the following description uses a mobile phone as an example. Specific embodiments of the electronic device of this application will be used to describe the electronic device of this application.

[0057] like Figure 1 As shown, Figure 1 This is a schematic diagram of the first embodiment of the electronic device provided in this application in a first state. Figure 2 This is a schematic diagram from another perspective when the first embodiment of the electronic device provided in this application is in a first state. Figure 3 This is a schematic diagram of the first embodiment of the electronic device provided in this application in a second state. The electronic device includes a first housing 1, a second housing 2, a screen, and a folding device. The screen can be a flexible screen used to display images, videos, etc. The specific type of flexible screen in this application is not limited. For example, the flexible screen can be an active-matrix organic light-emitting diode (AMOLED) display. As a self-emissive display, AMOLED does not require a backlight module (BLM). Therefore, when the substrate in the AMOLED display is made of a flexible resin material, such as polyethylene terephthalate (PET), the AMOLED display can have bendable characteristics. For example, the flexible screen can also be an organic light-emitting diode (OLED) display, a mini organic light-emitting diode (MLED) display, a micro organic light-emitting diode (MOLED) display, a micro organic light-emitting diode (MOLED) display, a quantum dot light-emitting diode (QLED) display, etc. In one possible implementation, such as Figure 2 As shown, the electronic device also includes a telephoto module 21 disposed in the second housing 2. The telephoto module 21 is used for long-distance shooting, such as... Figure 2 As shown, the telephoto module 21 is located on the side of the second housing 2 away from the second screen along the thickness direction of the electronic device. The telephoto module 21 can be used as a rear camera for taking pictures.

[0058] like Figure 3 As shown, the first housing 1 and the second housing 2 are spaced apart, and the first housing 1 and the second housing 2 can also be the mid-frame structure of the electronic device. The first housing 1 and the second housing 2 are used to install components such as batteries, circuit boards, cameras, headphones, earpieces, buttons, and batteries of the electronic device. The first housing 1 and the second housing 2 are also used to support the screen, that is, the screen is fixedly connected (e.g., pasted) to the first housing 1 and the second housing 2, so that the screen remains as flat as possible during use and to protect the non-display surface of the screen. The folding device 3 is located between the first housing 1 and the second housing 2 and is connected to the first housing 1 and the second housing 2. Specifically, the first housing 1 is provided with a first groove, and the second housing 2 is provided with a second groove. A part of the folding device 3 is installed in the first groove, and another part is installed in the second groove. In some possible embodiments, the folding device 3 can be connected to the first groove and the second groove by means of screws or the like.

[0059] During the use of the electronic device, the folding device 3 includes at least the following: Figure 1 and Figure 2 The first state shown (i.e., the folded state) and Figure 3 The second state (i.e., the unfolded state) is shown. In this state, the first housing 1 and the second housing 2 are approximately on the same plane, making the flexible screen approximately planar. At this time, the flexible screen is exposed, allowing the user to operate it and display images or videos, thus achieving a large-screen display and improving the user's viewing experience. Furthermore, when the folding device is in the second state, the first housing 1 and the second housing 2 can rotate, thereby folding the device. During the folding process, the ends of the first housing 1 and the second housing 2 furthest from the folding device move closer together, causing the electronic device to... Figure 1 and Figure 2 The first state is shown. In this first state, the electronic device is easy to store and carry. Furthermore, when the folding device is in the first state, the first housing 1 and the second housing 2 can rotate, thereby unfolding the folding device and allowing the electronic device to be stored in a folding position. Figure 3 The second state is shown. Therefore, in the solutions provided in the embodiments of this application, the folding device is used to realize the folding and unfolding of the electronic device.

[0060] Those skilled in the art will understand that the structures illustrated in the embodiments of this application do not constitute a specific limitation on the electronic device. In other possible embodiments of this application, the electronic device may include more components than illustrated, or combine some components, or split some components, or have different component arrangements.

[0061] from Figure 1 and Figure 2 It can be seen that when the electronic device is in the first state, the first housing 1 and the second housing 2 are stacked along the thickness direction of the electronic device. From Figure 3 It can be seen that when the electronic device is in the second state, the first housing 1 is located on one side of the second housing 2 along the width direction of the electronic device. During the use of the electronic device, the first housing 1 and the second housing 2 can have a certain angle between them according to the usage requirements. The degree of the angle can be α, and 0° < α < 180°, that is, the first housing 1 and the second housing 2 are relatively tilted, and the tilt angle can be adjusted according to the usage requirements.

[0062] In one specific embodiment, such as Figure 1 As shown, the screen may include a first screen 4 and a second screen 5. The first screen 4 is located on one side of the first housing 1 along the thickness direction of the electronic device and covers the first housing 1, as shown. Figure 4 As shown, Figure 4 This is a schematic diagram from another perspective showing the first embodiment of the electronic device provided in this application in its second state. The second screen 5 is located on the side of the first housing 1 away from the first screen 4 along the thickness direction of the electronic device, and the second screen 5 covers both the first housing 1 and the second housing 2. The first screen 4 can be a secondary screen of the electronic device, and the second screen 5 can be the main screen of the electronic device.

[0063] Typically, to make electronic devices easier to access when folded, their width is usually small when folded. In related technologies, such as... Figure 5 and Figure 6 As shown, Figure 5 A schematic diagram of the second embodiment of the electronic device provided in this application when it is in the first state. Figure 6 This is a schematic diagram from another angle showing the second embodiment of the electronic device provided in this application in its first state. The width X of the electronic device in its folded state is also shown. ′ 1 and length Y ′ The aspect ratio between the two screens is approximately 9:20. To adapt to the structure of the electronic device, the aspect ratio of the first screen 4 is approximately the same as that of the electronic device when it is folded, that is, the ratio between the width and length of the first screen 4 is also approximately 9:20. When unfolded, as shown... Figure 7 As shown, Figure 7This is a schematic diagram of the second embodiment of the electronic device provided in this application when it is in a second state. The length Y of the electronic device is... ′ and width X ′ The aspect ratio of the second screen (5) is close to 1:1, and its size is usually adapted to the size of the electronic device. Therefore, the aspect ratio of the second screen (5) is also close to 1:1, and its shape is approximately square. However, the width-to-length ratio of mainstream video media on electronic devices is usually 16:9, and the width-to-length ratio of photos is usually 4:3. When the electronic device is unfolded and displays videos or pictures on the second screen (5), the significant difference between the aspect ratio of the second screen (usually close to 1:1) and the aspect ratio of the video or picture (usually 4:3) results in a smaller effective viewable area of ​​the second screen (5). This means that there will be large "black borders" on both sides of the video or picture, and part of the second screen (5) will not be used for display, leading to low utilization of the second screen (5) and affecting the user experience. Figure 7 Taking the scheme shown as an example, Figure 7 In the solution shown, the width-to-length ratio of the second screen 5 is approximately 1:1, while the width-to-length ratio of the image 9 to be displayed is 4:3. When displayed, large "black borders" will be generated on the top and bottom sides of the image 9, i.e., the shadow areas in the figure, which will affect the user experience.

[0064] When the electronic device is in a folded state, the first screen 4 and the telephoto module 21 are located on opposite sides of the electronic device, and the second screen 5 is located between the first housing 1 and the second housing 2 along the thickness direction of the electronic device; at this time, the second screen 5 is in a folded state. When the electronic device is in an unfolded state, as shown... Figure 8 As shown, Figure 8 This is a schematic diagram from another perspective showing the second embodiment of the electronic device provided in this application in a second state. The telephoto module 21 and the first screen 4 are located on the same side of the electronic device, and the second screen 5 is as follows. Figure 7 As shown, it is in the unfolded state.

[0065] Typically, the telephoto module 21 of electronic devices is a periscope module, such as... Figure 9 As shown, Figure 9This is a schematic diagram of the telephoto module 21 provided in an embodiment of this application. The telephoto module 21 includes a first reflector 211, a second reflector 212, and a lens group 213. The lens group 213 includes multiple lenses. Light is reflected by the first reflector 211, and the reflected light passes through the lens group 213. The lens group 213 is used to adjust the light. The light adjusted by the lens group 213 is transmitted to the second reflector 212, which is used to reflect the light to the sensor 214. The arrow indicates the direction of light transmission. The first reflector 211 and the second reflector 212 are arranged along the width direction of the telephoto module 21. The lens group 213 is located between the first reflector 211 and the second reflector 212. The telephoto module 21 reflects light along the width direction of the telephoto module 21 through the first reflector 211, thereby reducing the size of the telephoto module 21 in the thickness direction, so as to facilitate the installation of the telephoto module 21 in a thinner electronic device. Generally, the larger the width dimension of the telephoto module 21, the greater its equivalent focal length and other parameters can be, thereby improving its performance. Furthermore, when the volume of the telephoto module 21 is larger, the volume of the sensor 214 arranged in the telephoto module 21 can also be increased. The increased volume of the sensor 214 can also improve the performance of the telephoto module 21. Therefore, when the width dimension of the telephoto module 21 is larger, the volume of the telephoto module 21 is larger, the equivalent focal length of the telephoto module 21 is greater, and the size of the sensor 214 is also relatively larger, resulting in better performance of the telephoto module 21.

[0066] Typically, the thickness direction of the telephoto module 21 is the same as the thickness direction of the electronic device. When setting up the telephoto module 21, its width direction is the same as the width direction of the electronic device; that is, the telephoto module 21 extends along the width direction of the electronic device. This design allows for a longer equivalent focal length telephoto module 21 without increasing the thickness of the electronic device, thereby improving the image quality. Simultaneously, this layout reduces the space occupied by the telephoto module 21 along the length direction of the electronic device, facilitating the placement of other electronic components and allowing for larger capacity batteries. However, due to the smaller width dimension of the electronic device, there are significant limitations on the width dimension of the telephoto module 21, which affects parameters such as the equivalent focal length, limiting performance improvements and impacting image quality.

[0067] To address the aforementioned technical problems, this application provides an electronic device that reduces the black borders on the second screen when displaying images by changing the aspect ratio of the electronic device, and enables the electronic device to use a higher-performance telephoto module, thereby improving the shooting quality of the electronic device.

[0068] Specifically, such as Figure 10 As shown, Figure 10 This is a schematic diagram from a first angle of a third embodiment of the electronic device provided in this application. The electronic device includes a first housing 1 and a second housing 2 connected by a folding device 3. A first screen 4 is disposed on the first housing 1, as shown below. Figure 11 As shown, Figure 11 This is a schematic diagram of the second angle of a third embodiment of the electronic device provided in this application, showing a telephoto module 21 disposed on the second housing 2. (See diagram below.) Figure 12 As shown, Figure 12 This is a schematic diagram of the third embodiment of the electronic device provided in this application, in a first state. The width of the first screen 4 of the electronic device is x1, the length is y1, and 2 / 3 ≤ x1 / y1 ≤ 8 / 9. In one possible implementation, the ratio of x1 / y1 can be 0.67, 0.70, 0.73, 0.76, 0.79, 0.80, 0.82, 0.84, 0.86, 0.88, etc. Figure 13 As shown, Figure 13 This is a schematic diagram of the third embodiment of the electronic device provided in this application when it is in the second state. The width of the second screen 5 is x2, the length is y2, and 4 / 3≤x2 / y2≤16 / 9. The ratio of x2 / y2 can be 1.34, 1.37, 1.40, 1.43, 1.46, 1.49, 1.53, 1.56, 1.59, 1.63, 1.66, 1.69, 1.73, 1.76, 1.77, etc.

[0069] This design allows the width-to-length ratio of the second screen 5 in its unfolded state to closely approximate the aspect ratio of media such as videos and images (typically 4:3). Therefore, during display, videos and images can be better displayed on the second screen 5, increasing its effective viewable area and utilization rate. Compared to related technologies where the width-to-length ratio of the unfolded second screen 5 is 18:20, the solution provided in this application has a width-to-length ratio closer to that of media such as videos and images. This reduces the possibility of "black borders" appearing on both sides of the second screen 5, thus improving the user experience.

[0070] Electronic devices are typically designed with a casing size close to the screen size to facilitate a full-screen design, thereby reducing black borders and improving the user experience. Furthermore, when 2 / 3 ≤ x1 / y1 ≤ 8 / 9 and 4 / 3 ≤ x2 / y2 ≤ 16 / 9, the width-to-length ratio of the electronic device in its folded state can be increased. For the same length, the electronic device provided in this embodiment has a larger width dimension; therefore, a longer telephoto module 21 with a larger width dimension can be used. For example... Figure 14As shown, Figure 14 This is a schematic diagram of the fourth embodiment of the electronic device provided in this application. The width of the first housing 1 is m, and the width of the telephoto module 21 is n, where n ≥ 40% m. That is, the width of the telephoto module 21 is not less than 40% of the width of the first housing 1, making the size of the telephoto module 21 disposed in the electronic device relatively large, thereby improving the performance of the telephoto module 21, including but not limited to increasing the equivalent focal length of the telephoto module 21 and increasing the optical zoom ratio, thereby improving the shooting quality of the electronic device.

[0071] In one possible implementation, the optical zoom ratio of the telephoto module 21 is *a*, the equivalent focal length of the telephoto module 21 is *b*, and 3 ≤ *a* ≤ 10, and / or, 70 mm ≤ *b* ≤ 240 mm. The optical zoom ratio of the telephoto module 21 can be 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, etc. The equivalent focal length of the telephoto module 21 can be 70 mm, 90 mm, 110 mm, 130 mm, 150 mm, 170 mm, 190 mm, 210 mm, 230 mm, 240 mm, etc.

[0072] Because of the increased size of the telephoto module 21, its optical zoom ratio and equivalent focal length can also be increased. A higher optical zoom ratio allows the electronic device to capture distant objects with better image quality. A longer equivalent focal length means stronger magnification, enabling the capture of distant objects with good clarity. During shooting, a longer focal length results in better background blur, thus better highlighting the subject. By increasing the optical zoom ratio and equivalent focal length of the telephoto module 21, it can be adapted to different shooting scenarios, including but not limited to portraits, landscapes, and flowers.

[0073] In one possible implementation, the sensor 214 is 1 / 1.4 inch to 1 inch in size, referring to the diagonal dimension of the sensor 214. For example... Figure 9 As shown, sensor 214 is disposed on one side of the second reflector 212 along the thickness direction of telephoto module 21, for receiving light reflected by the second reflector 212. The diagonal size of sensor 214 can be from 1 / 1.4 inch to 1 inch, including but not limited to 1 / 1.3 inch, 1 / 1.2 inch, 1 / 1.1 inch, 1 inch, etc. The aspect ratio of sensor 214 can be 4:3.

[0074] In the solution provided in this application embodiment, the performance of the telephoto module 21 can be improved by increasing the size of the sensor 214. When the size of the sensor 214 of the telephoto module 21 is increased, the amount of light entering the telephoto module 21 and the image quality can be effectively improved, especially the shooting quality in low-light environments. At the same time, the larger sensor 214 has better resolution and can maintain higher image quality during zooming, which is conducive to achieving better zoom effects.

[0075] Usually, such as Figure 14 As shown, circuit boards 6, mid-frames, and other structures are also arranged around the telephoto module 21. These structures occupy space in the width direction of the electronic device, causing the dimensions of the telephoto module 21 in the width direction of the electronic device to differ from the dimensions of the electronic device in the width direction. Therefore, while reserving installation space for the circuit boards 6, mid-frames, and other structures, the dimensions of the telephoto module 21 in the width direction of the electronic device should be increased as much as possible. Figure 14 As shown, in one possible implementation, the width m of the first housing 1 and the width n of the telephoto module 21 also satisfy n ≤ 80% m. The width of the telephoto module 21 can be 40% m, 45% m, 50% m, 55% m, 60% m, 65% m, 70% m, 75% m, 80% m, etc. The width direction of the telephoto module 21 can be the same as the width direction of the electronic device. This design can reduce the space occupied by the telephoto module 21 in the length direction of the electronic device, so that the electronic device can have more space for arranging the battery 7, which can improve the battery life of the electronic device.

[0076] When the size of the telephoto module 21 is less than 40%m, its small size limits its overall performance and affects image quality. When the size of the telephoto module 21 is greater than 80%m, its excessive size affects the arrangement of the circuit board 6, the mid-frame, and other structures, requiring a readjustment of the internal structure of the electronic device. Furthermore, insufficient installation space for the circuit board 6 and the mid-frame can negatively impact the stability of electrical connections to other components and the structural strength of the electronic device, making it prone to damage. Therefore, the solution provided in this application allows the size of the telephoto module 21 to be between 40%m and 80%m. This maximizes the performance of the telephoto module 21 while minimizing its impact on other components, better meeting practical usage requirements.

[0077] In one possible implementation, such as Figure 14 As shown, the dimension n of the telephoto module 21 along the width direction of the electronic device satisfies: 40 mm ≤ n ≤ 80 mm.

[0078] This design improves the performance of the telephoto module 21 while reducing the impact of its increased size on other components of the electronic device. The telephoto module 21 can be 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, or 80mm in size. The specific dimensions of the telephoto module 21 can be adjusted according to the width of the electronic device when it is folded.

[0079] In one possible implementation, when the electronic device is in its first state, i.e., in a folded state, the thickness of the electronic device is 4 mm to 6 mm. When the electronic device is in its second state, i.e., in an unfolded state, the thickness of the electronic device is 8 mm to 12 mm.

[0080] When the electronic device is in its unfolded state, its thickness can be 4.0 mm, 4.2 mm, 4.4 mm, 4.6 mm, 4.8 mm, 5.0 mm, 5.2 mm, 5.4 mm, 5.6 mm, 5.8 mm, 6.0 mm, etc. When the electronic device is in its folded state, its thickness can be 8.0 mm, 8.4 mm, 8.8 mm, 9.2 mm, 9.6 mm, 10.0 mm, 10.4 mm, 10.8 mm, 11.2 mm, 11.6 mm, 12.0 mm, etc.

[0081] The electronic device provided in this application embodiment has a relatively small thickness in both the folded and unfolded states. In the solution provided in this application embodiment, the ratio of the width to the length of the electronic device is increased. Therefore, when the length of the electronic device remains unchanged, by reducing the thickness of the electronic device, the possibility that the increased width of the electronic device will make it inconvenient to pick up can be reduced to a certain extent, thereby making it easier for users to pick up the electronic device and improving the user experience.

[0082] like Figure 12 As shown, in one possible implementation, the first screen 4 has a first edge 41 along the width direction of the electronic device, and the first housing 1 has a second edge 11 along the width direction of the electronic device. Since the edges of the electronic device may have structures such as a mid-frame and a folding device 3, the first edge 41 of the first screen 4 cannot completely overlap with the second edge 11 of the first housing 1, and there is usually a certain gap. The minimum distance between the first edge 41 and the second edge 11 is c, and 0.8 mm ≤ c ≤ 3 mm.

[0083] When the distance between the first edge 41 and the second edge 11 is less than 0.8 mm, the distance is too small, resulting in insufficient space at the edge of the first housing 1. This can easily lead to a reduction in the width of the middle frame, which not only reduces the structural strength of the middle frame but also increases the difficulty of placing components on it. When the distance between the first edge 41 and the second edge 11 is greater than 3 mm, the distance is too large, resulting in a large black border around the first screen 4 during use. Furthermore, this design occupies space on the first screen 4, making it smaller and affecting the user experience. Therefore, the distance between the first edge 41 and the second edge 11 is typically between 0.8 mm and 3 mm. This design meets the structural requirements of electronic devices, reduces the size of the black border, and improves the user experience.

[0084] The distance between the first edge 41 and the second edge 11 can be 0.8 mm, 1.0 mm, 1.2 mm, 1.6 mm, 1.8 mm, 2.0 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, 3.0 mm, etc.

[0085] like Figure 13 As shown, in one possible implementation, along the width direction of the electronic device, the second screen 5 has a third edge 51, the first housing 1 has a fourth edge 12, and the second housing 2 has a fifth edge 23. Since components such as a mid-frame need to be provided around the second screen 5, the third edge 51 of the second screen 5 usually cannot coincide with the fourth edge 12 and the fifth edge 51, and a certain amount of space needs to be reserved. Moreover, during the folding and unfolding process, the edge of the second screen 5 will usually undergo a certain amount of displacement relative to the first housing 1 and the second housing 2 along the width direction of the electronic device, so a certain amount of movement space needs to be reserved. The distance between the third edge 51 and the fourth edge 12 and the distance between the third edge 51 and the fifth edge 23 are both d, and 0.8≤d≤4 mm.

[0086] When the distance between the third edge 51 and the fourth edge 12 and the fifth edge 23 is less than 0.8 mm, the space reserved at the edge of the second screen 5 is too small. This will affect the arrangement space of the electronic device's frame and other electronic components, and the limited space for movement of the second screen 5 will easily lead to creases during use. When the distance between the third edge 51 and the fourth edge 12 and the fifth edge 23 is greater than 4 mm, the distance between the third edge 51 and the fourth edge 12 is too large, resulting in a large black border during use, which reduces the screen-to-body ratio of the second screen 5 and affects the user experience. Therefore, in the solution provided by this application embodiment, the dimension between the third edge 51 and the fourth edge 12 and the fifth edge 23 is 0.8 mm to 4 mm, which meets the usage requirements while reducing the size of the black border, making it more in line with actual usage needs.

[0087] The distance between the third edge 51 and the fourth edge 12 and the fifth edge 23 can be 0.8 mm, 1.0 mm, 1.2 mm, 1.6 mm, 1.8 mm, 2.0 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, 3.0 mm, 3.2 mm, 3.4 mm, 3.6 mm, 4.0 mm, etc.

[0088] like Figure 14 As shown, in one possible implementation, the electronic device may further include a first camera module 22, which is disposed in the second housing 2, such as... Figure 15 As shown, Figure 15This is a schematic diagram of a fifth embodiment of the electronic device provided in this application. The first camera module 22 may include a main camera module 221, which is located on one side of the telephoto module 21 along the width direction of the second housing 2. The circuit board includes a first circuit board 61, a second circuit board 62, and a third circuit board 63. The battery includes a first battery 71 and a second battery 72. The electronic device may also include a second camera module 8. The first circuit board 61 and the first battery 71 are disposed in the second housing 2. The first circuit board 61 may be disposed circumferentially along the telephoto module 21 and the first camera module 22. Along the length direction of the second housing 2, the first battery 71 is located on one side of the telephoto module 21. The first circuit board 61 is used to house a storage module, sensors of the camera module, etc. The second circuit board 62, the third circuit board 63, the second battery 72, and the second camera module 8 are disposed in the first housing 1. Along the length direction of the first housing 1, the second circuit board 62 and the third circuit board 63 are located on opposite sides of the second battery 72. The second camera module 8 is disposed on the side of the second battery 72 facing the second circuit board 62. When the electronic device is in the first state, the second camera module 8 can be used as a front-facing camera for taking pictures. The telephoto module 21 can be used as a rear-facing camera for taking pictures. The second circuit board 62 can be used to set up signal units, including but not limited to setting up antennas, etc. The third circuit board 63 can be used to set up components such as speakers and motors.

[0089] By arranging the telephoto module 21 and the main camera module 221 along the width of the electronic device, the space occupied by the telephoto module 21 and the first camera module 22 in the length of the electronic device can be reduced, thereby reserving more space for arranging structures such as batteries, so as to improve the battery life and other performance of the electronic device.

[0090] like Figure 16 As shown, Figure 16 This is a schematic diagram of a sixth embodiment of the electronic device provided in this application. In one possible implementation, the first camera module 22 may further include a wide-angle module 222, and the electronic device may be a triple-camera structure. Along the width direction of the second housing 2, the main camera module 221 and the wide-angle module 222 are located on one side of the telephoto module 21, while along the length direction of the second housing 2, the main camera module 221 and the wide-angle module 222 are arranged sequentially.

[0091] By setting the wide-angle module 222, a wider field of view can be achieved during shooting, allowing for the capture of more content and better detail. The wide-angle module 222 is suitable for various shooting scenarios and can reduce the impact of camera shake on image quality.

[0092] like Figure 17 As shown, Figure 17This is a schematic diagram of a seventh embodiment of the electronic device provided in this application. In one possible implementation, the first camera module 22 may further include a multispectral module 223. The electronic device can be a quad-camera structure. Along the width direction of the second housing 2, the main camera module 221 is located on one side of the telephoto module 21, and the wide-angle module 222 and the multispectral module 223 are located on the other side of the telephoto module 21. Along the length direction of the second housing 2, the wide-angle module 222 and the multispectral module 223 are arranged sequentially.

[0093] The multispectral module 223 can be used to improve the accuracy of color reproduction, improve color cast, thereby enhancing shooting effects and improving shooting quality.

[0094] Figure 16 and Figure 17 In the illustrated embodiment, the structure and layout of the corresponding region of the first housing 1 can be the same as... Figure 15 The layout of the illustrated embodiment is the same, and will not be described again here.

[0095] like Figure 18 As shown, Figure 18 This is a cross-sectional schematic diagram of the electronic device provided in an embodiment of this application. In one possible implementation, the electronic device includes a circuit board 6 disposed inside the second housing 2. The circuit board 6 has a recessed portion 64 recessed along the thickness direction of the electronic device. A portion of the telephoto module 21 is located within the recessed portion 64, so that the telephoto module 21 can be embedded in the circuit board 6. The circuit board 6 and the telephoto module 21 partially overlap in the thickness direction. Compared to the distribution of the telephoto module and the circuit board along the thickness direction of the electronic device, the thickness of the electronic device can be reduced, which is beneficial for the lightweight design of the electronic device.

[0096] In the solution provided in this application embodiment, when the electronic device is folded, the first screen 4 serves as the outer screen, with a width-to-length ratio of 3:2 to 9:8. When the electronic device is unfolded, the width-to-length ratio of the second screen 5 is 4:3 to 16:9. This design allows the second screen 5 to better adapt to the size ratio of mainstream media, which is beneficial for increasing the effective viewing area of ​​the second screen 5 and improving the user experience. The size of the telephoto module 21 occupies more than 40% of the width of the second housing 2, which maximizes the size of the telephoto module 21 and thus improves its performance. The solution provided in this application embodiment increases the width-to-length ratio of the electronic device in the folded state, thereby reducing the limitation of the electronic device's size on the performance improvement of the telephoto module 21.
