Description

terminal

[0001] This application claims priority to Chinese patent application filed on April 24, 2024, with application number 202410505970.0 and title "Terminal", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of terminals, and more particularly to a terminal. Background Technology

[0003] Currently, some devices have relatively small screen sizes, such as phablets and foldable phones with small foldable screens. The size of the back screen of these devices is sometimes less than one-third or one-quarter of the size of the front screen, which makes it difficult for users to view the back screen. Summary of the Invention

[0004] This application provides a terminal that improves upon the problem of small rear screen size in existing devices.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] This application provides a terminal, comprising a main body, a circuit board assembly, a screen assembly, a camera assembly, and a flash assembly. The main body includes at least a first target portion and a second target portion connected together. It is understood that the first target portion and the second target portion can be directly connected or indirectly connected, such as integrally formed, rotatably connected, or slidably connected. The circuit board assembly includes a first circuit board and a second circuit board. The first circuit board is disposed on the first target portion and electrically connected to the first screen and the first camera, respectively. The second circuit board is disposed on the second target portion. The second circuit board is generally electrically connected to the first circuit board, but may not be connected, depending on the function and usage requirements of the first and second circuit boards. The screen assembly includes a first screen, disposed on a first surface of the first target portion and connected to the first circuit board. The first surface can be the front or back of the first target portion, depending on usage requirements. The camera assembly includes a first camera, disposed on the first surface of the first target portion. The flash assembly includes a first flash, disposed on the second target portion. The first flash is electrically connected to the circuit board assembly. The first flash can be connected to either the first or second circuit board in the circuit board assembly, or it can be connected to other circuit boards if other circuit boards are present in the circuit board assembly. The specific connection depends on the usage requirements. The terminal provided in this application embodiment changes the location of the first flash, so that the first camera and the first screen are still located on the same surface of the same part, but the first flash is located on a different part. This allows the space originally used for installing the first flash in the part where the first screen is located (i.e., the first target part) to be used for installing the first screen, which can increase the maximum manufacturing area of ​​the first screen to a certain extent, improve the integrity and display effect of the first screen, and also improve the aesthetic appearance of the terminal to a certain extent.

[0007] In one possible implementation of the first aspect, the second target portion includes a first side surface and a second side surface disposed opposite to the first side surface. The first side surface is a side surface of the outer periphery of the second target portion that connects to or is close to the first target portion. The distance between the first flash and the first side surface is less than or equal to a first preset value. The first preset value is less than or equal to half the distance between the first side surface and the second side surface of the second target portion. This allows the first flash to be closer to the first target portion, and thus closer to the first camera, providing better illumination for the first camera.

[0008] In one possible implementation of the first aspect, the second target portion includes a third side and a fourth side disposed opposite to the third side. The third side is one of the sides connecting the first side and the second side on the outer peripheral surface of the second target portion. The distance between the first flash and the third side is less than or equal to a second preset value, which is less than half the distance between the third side and the fourth side of the second target portion. This allows the first flash to be positioned close to the edge of the second target portion, reducing the risk of it being blocked by a hand.

[0009] In one possible implementation of the first aspect, the first flash is located in the corner area near the junction of the first side and the third or fourth side. The range of the corner area can be set as needed. For example, it can be defined as an area near the connecting line between the first and third sides or the connecting line between the first and fourth sides, and the area is less than or equal to 1 / 4 or 1 / 3 of the projection area of ​​the second target part on the horizontal plane. Regardless of the setting method, placing the first flash in the corner area formed by the first side and the third or fourth side allows the first flash to be positioned close to both ends of the first side. This makes it easier for the first flash to be located in the gap between the thumb and palm when the terminal is held, which not only does not affect the user experience of holding the terminal, but also reduces the risk of the first flash being blocked, achieving multiple benefits.

[0010] In one possible implementation of the first aspect, the first flash and the first camera are positioned on the same side of the centerline along the length of the main body. This allows the first flash and the first camera to be closer together, resulting in better illumination of the first camera by the first flash.

[0011] In one possible implementation of the first aspect, the second circuit board is electrically connected to the first circuit board via a first electrical connector. This ensures stable signal connection between the first and second circuit boards.

[0012] In one possible implementation of the first aspect, the first flash unit is electrically connected to the second circuit board via a second electrical connector. This ensures stable signal connection between the first flash unit and the second circuit board, and also reduces the risk of damage to the second electrical connector if the terminal has a foldable structure, as the second electrical connector does not need to be mounted through a shaft.

[0013] In one possible implementation of the first aspect, the second electrical connector is spaced apart from the first electrical connector. Since the terminal typically also includes a battery, and at least a portion of the first electrical connector is stacked with the battery, the thickness of the area corresponding to the first electrical connector is relatively large. The spaced-apart arrangement of the second electrical connector prevents it from overlapping with the first electrical connector, thus ensuring that the placement of the second electrical connector does not adversely affect the thickness of the terminal.

[0014] In one possible implementation of the first aspect, the terminal further includes a battery. The battery is disposed on the second target portion and electrically connected to the first circuit board and / or the second circuit board to power both. A gap exists between the battery and the edge of the second target portion, and at least a portion of the second electrical connector is located within the gap. This allows the thickness of the battery-second electrical connector assembly to be comparable to the thickness of the battery, preventing the thickness of the corresponding area of ​​the battery from increasing due to the placement of the second electrical connector, thereby resulting in a smaller terminal thickness.

[0015] In one possible implementation of the first aspect, the terminal further includes a battery protection board. A first portion of the battery protection board is located within the gap and connected to the second target portion, while a second portion of the battery protection board contacts the battery to secure it to the second target portion. At least a portion of the second electrical connector is stacked on top of the first portion. This allows for efficient use of the space within the aforementioned gap, resulting in a compact internal structure for the terminal and facilitating miniaturization design.

[0016] In one possible implementation of the first aspect, the battery is electrically connected to the second circuit board via a fourth electrical connector, with at least a portion of the second electrical connector stacked on top of at least a portion of the fourth electrical connector. This allows for efficient use of the terminal's internal space, resulting in a compact internal structure and facilitating miniaturization design.

[0017] In one possible implementation of the first aspect, the first, second, and fourth electrical connectors all include flexible circuit boards. This allows the aforementioned electrical connectors to reduce bending during installation as needed, meeting the requirements of different installation environments and improving the installation speed of the aforementioned electrical connectors to a certain extent.

[0018] In one possible implementation of the first aspect, the first flash unit is electrically connected to the first electrical connector. This eliminates the need for a separate adapter connector for the first flash unit, resulting in fewer components within the terminal.

[0019] In one possible implementation of the first aspect, the first flash unit is electrically connected to the first electrical connector via a third electrical connector. The third electrical connector allows the placement of the first flash unit to be independent of the location of the first electrical connector, making the design and installation of the first flash unit more convenient.

[0020] In one possible implementation of the first aspect, the terminal further includes a photosensor module. The photosensor module is disposed on at least one of the first target portion, the second target portion, the first camera, the first screen, and the first flash. The photosensor module is used to detect the ambient brightness on the light-receiving side of the first camera. At least one of the first and second circuit boards is provided with a control module, which is used to receive the signal output by the photosensor module and control the first screen and / or the first flash to illuminate according to the signal output by the photosensor module, thereby providing supplementary lighting for the first camera. By adopting the above scheme, the terminal can not only provide supplementary lighting for the first camera through the first flash, but also through the first screen, and different supplementary lighting schemes can be implemented through the cooperation of the photosensor module and the control module to meet the needs of capturing images through the first camera under different ambient brightness conditions.

[0021] In one possible implementation of the first aspect, the control module can control the first screen to switch between at least two brightness levels based on the signal output by the photosensitive module. This allows the terminal to control the brightness of the first screen according to the ambient brightness, thereby providing supplementary lighting for the first camera to meet shooting needs in different environments, reducing unnecessary energy waste, and minimizing the risk of overexposure during shooting.

[0022] In one possible implementation of the first aspect, the first screen is used to display a preset image to provide supplementary lighting for the first camera when it is in operation. The preset image can be any image with high brightness, as long as it can provide supplementary lighting for the first camera. This approach allows the first screen to provide relatively high brightness when illuminating the first camera, thereby achieving the supplementary lighting effect.

[0023] In one possible implementation of the first aspect, the preset screen is a white screen. The brightness of a white screen is generally higher than that of other screens. Using a white screen as the preset screen can make the brightness of the first screen higher, so as to meet the supplementary lighting needs.

[0024] In one possible implementation of the first aspect, multiple parts are sequentially rotated and connected. This allows the terminal to be foldable, enabling the terminal's state to be changed according to usage needs to meet different requirements.

[0025] In one possible implementation of the first aspect, the screen assembly further includes a second screen located on a second side of the main body. The second screen covers at least a portion of the first target portion and at least a portion of the second target portion, and is electrically connected to the circuit board assembly. Using the terminal provided in this embodiment, the terminal can have multiple screens, and both sides can be viewed, thus meeting various usage environments. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0039] In the description of this application, it should be understood that the terms "inner" and "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] To facilitate a clear description of the technical solutions in the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish identical or similar items with essentially the same function and effect. For example, the first limiting part and the second limiting part are only used to distinguish different limiting parts and do not limit their order. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and the terms "first" and "second" are not necessarily different.

[0041] It should be noted that in this application, the terms "in one embodiment" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "in one embodiment" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "in one embodiment" or "for example" is intended to present the relevant concepts in a specific manner.

[0042] In this application, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0043] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0044] In recent years, with the continuous development of screen technology, mobile phones, computers, and other terminal devices no longer have only one screen. Some terminals have two screens, one on the front and the other on the back. Generally, the screen on the front is larger, while the screen on the back is smaller. This caters to different consumer needs, facilitates operation, and enhances the overall user experience.

[0045] However, the screen size on the back of current devices is generally small. For example, the back screen size of tablet phones and small foldable phones (such as mini foldable phones) is generally less than half the size of the front screen, and some are even less than one-third or one-quarter the size of the front screen. This makes it difficult for users to view the back screen. The aforementioned mini foldable phone refers to a phone that adopts a vertical folding design. When unfolded, its front flexible screen is about the same size as the front screen of a regular tablet phone. When folded, the flexible screen on the front of the phone folds vertically, and the vertical length of the phone is less than that of a regular tablet phone. For example, the vertical length of the phone when folded can be half or less than that of a regular tablet phone.

[0046] To improve, or at least partially improve, the present application provides a terminal. This terminal changes the location of the flash on the back of the main body, so that the camera and screen on the back of the main body are still located on the same part, but the flash is located on a different part. This allows the space originally used for mounting the flash on the back screen to be used for mounting the screen, thereby increasing the maximum manufacturing area of ​​the back screen to a certain extent.

[0047] The terminals provided in this application embodiment may include, but are not limited to, mobile phones, tablets, laptops, e-book readers, wearable devices, in-vehicle devices, augmented reality (AR) / virtual reality (VR) devices, laptops, ultra-mobile personal computers (UMPCs), netbooks, personal digital assistants (PDAs), handheld mobile terminals, dashcams, etc.

[0048] For ease of explanation, the following embodiments use a mobile phone as an example of a terminal according to an embodiment of this application.

[0049] Figure 1 is a rear view structural diagram of a mobile phone according to an embodiment of this application, where the flash assembly is not shown. As shown in Figures 1 and 2, the mobile phone includes a main body 100, and a screen assembly 200 and a camera assembly 300 disposed on the main body 100.

[0050] The main body 100 generally has two large surfaces arranged opposite each other, one of which is the front and the other is the back. The front and back can be defined arbitrarily. Generally, when the main body 100 is provided with only one screen, the surface where the screen is located is defined as the front. When both large surfaces of the main body 100 are provided with screens, the surface with the larger screen size is defined as the front.

[0051] The screen assembly 200 includes at least a first screen 210. The first screen 210 is relatively small and is generally located on the back of the main body 100. Figure 2 is a side view of the mobile phone shown in Figure 1. As shown in Figure 2, the screen assembly generally also includes a second screen 220. The second screen 220 is relatively large and is generally located on the front of the main body 100. In special cases, the screen assembly 200 may only include the first screen 210, or the screen assembly 200 may include both the first screen 210 and the second screen 220, but the first screen 210 may be located on the front of the main body 100 and the second screen 220 may be located on the back of the main body 100, depending on the specific needs. For ease of description and distinction, the large surface containing the first screen 210 can be defined as the first surface, and the large surface containing the second screen 220 can be defined as the second surface. That is, when the first screen 210 is located on the back of the main body 100, the back of the main body 100 is the first side and the front of the main body 100 is the second side; when the first screen 210 is located on the front of the main body 100, the front of the main body 100 is the first side and the back of the main body 100 is the second side.

[0052] The camera assembly 300 may include one or more cameras. At least one camera is located on the rear side of the main body 100.

[0053] Figure 3 is a schematic diagram of the internal structure of a mobile phone in related technologies. The terminal also includes a flash. Since the closer the flash is to the camera, the better its supplementary lighting effect for imaging, to ensure the supplementary lighting effect, the position and arrangement of the flash 310' in most terminals on the market are shown in Figure 3. The flash 310' and the camera 210' are arranged adjacent to each other, both mounted on the back of the phone. This results in a smaller screen size on the back of the main body 100'.

[0054] The terminal provided in this application embodiment changes the above-described configuration. As shown in Figures 4 and 5, Figure 4 is a rear view and a side view of the terminal provided in this application embodiment in its unfolded state, and Figure 5 is a rear view and a side view of the terminal provided in this application embodiment in its folded state. The main body 100 of this terminal includes multiple parts connected in sequence. The connection mentioned here can be an integral molding connection, or a rotating connection, a sliding connection, etc., depending on the usage requirements. It is understood that when multiple parts are rotatably connected, the main body 100 generally has an unfolded state (as shown in Figure 4) and a folded state (as shown in Figure 5). At this time, two adjacent parts are generally rotatably connected by a pivot structure. Each part includes at least one frame, and in addition, at least one part may also include a shell 130, etc., disposed on the frame, depending on the usage requirements. The ends of two adjacent parts near the pivot structure can rotate around the pivot located between the two parts, thereby making the ends of the two parts away from the pivot structure relatively closer or relatively farther away, so that the terminal presents different states such as folded or unfolded. The pivot can be a physical pivot or a virtual pivot. When the hinge is a virtual hinge, it is not entirely composed of physical components of the foldable phone. Instead, it is a virtual rotating line formed by the shape and displacement constraints of different components within the foldable phone during relative movement. Adjacent parts of the foldable phone will rotate relative to each other around this virtual hinge during relative movement.

[0055] As shown in Figure 6, Figure 6 is a side view structural diagram of a terminal provided in an embodiment of this application. In this embodiment, the first screen is disposed on the back of one of the aforementioned parts. For ease of description, the part containing the first screen is referred to as the first target part 110. A housing 130 can be disposed on the back of the other parts of the main body 100. As shown in Figure 6, the main body 100 includes two parts, one of which is the aforementioned first target part 110, and the other part can be referred to as the second target part 120. A housing 130 can be disposed on the back of the second target part 120. This housing 130 can be a battery 600 cover (the battery 600 cover can be made of glass, glass with a film, vegan leather, fiberglass, etc.), or other housings, such as decorative shells, protective shells, etc. It should be noted that the aforementioned first target part 110 and second target part 120 can be rotatably connected or integrally formed. When the first target portion 110 and the second target portion 120 are integrally formed, the dashed line a in Figure 6 is the boundary line between the first target portion 110 and the second target portion 120. This dashed line is an auxiliary line drawn for ease of understanding and is not a structural line. When the first target portion 110 and the second target portion 120 are rotatably connected, the dashed line a in Figure 6 can be drawn as a solid line and used as a structural line. In other embodiments, the main body 100 can also adopt other configurations, which are not limited here.

[0056] As shown in Figure 7, which is a side view structural diagram of a terminal provided in another embodiment of this application, when the screen assembly 200 further includes a second screen 220, the second screen 220 can cover at least a portion of the first target portion 110 and at least a portion of the second target portion 120. It is understood that when the first target portion 110 and the second target portion 120 are integrally formed, the second screen 220 can be a flexible screen or a rigid screen, depending on the usage requirements. When the first target portion 110 and the second target portion 120 are rotatably connected, the second screen 220 can be a flexible screen, capable of bending with the rotation of either the first target portion 110 or the second target portion 120.

[0057] As shown in Figure 8, Figure 8 is a schematic diagram of the internal structure of a terminal provided in an embodiment of this application. The terminal provided in this embodiment, in addition to the main body 100 and screen assembly 200 described above, also includes a camera assembly 300, a flash assembly 400, and a circuit board assembly 500. The camera assembly 300 includes at least a first camera 310, which is disposed on the back of the first target portion 110. The flash assembly 400 includes at least a first flash 410. The first flash 410 is disposed on the second target portion 120. It is understood that the first flash 410 is generally disposed on the back of the second target portion 120. When the first target portion 110 and the second target portion 120 are rotatably connected, the first flash 410 may be disposed not only on the back of the second target portion 120 but also on the side of the second target portion 120 near the first target portion 110.

[0058] The circuit board assembly 500 includes at least a first circuit board 510 and a second circuit board 520. Electronic components are respectively mounted on the first circuit board 510 and the second circuit board 520. The type and quantity of electronic components can be determined according to the usage requirements of the electronic device. For example, the first circuit board 510 can be equipped with a SOC (System on Chip) chip, a CPU (Central Processing Unit / Processor), or other control modules, serving as a motherboard; alternatively, both the first and second circuit boards 510 can be equipped with the aforementioned control modules, depending on the usage requirements. The first circuit board 510 is mounted on the first target portion 110 and electrically connected to the first screen (not shown) and the first camera 310, respectively. The second circuit board 520 is mounted on the second target portion 120. In this embodiment, the second circuit board 520 can be electrically connected to the first circuit board 510 via an electrical connector, or wirelessly connected via a wireless communication module, or the second circuit board 520 and the first circuit board 510 can be independent of each other without connection, depending on the usage requirements. The first flash 410 is electrically connected to the second circuit board 520 or the first circuit board 510. The second screen is electrically connected to the first circuit board 510 or the second circuit board 520.

[0059] The terminal provided in this application embodiment changes the setting position of the first flash 410, so that the first camera 310 and the first screen are still located on the same surface of the same part, but the first flash 410 is set on other parts, that is, the first camera 310 and the first screen are set on the first target part 110, and the first flash 410 is set on the second target part 120. This allows the space in the first target part 110 that was originally used to install the first flash 410 to be used to install the first screen, which can increase the maximum manufacturing area of ​​the first screen to a certain extent, improve the integrity and display effect of the first screen, and also improve the appearance of the terminal to a certain extent.

[0060] To enable the first flash 410 to better illuminate the first camera 310, the first flash 410 can be positioned close to the first target portion 110. The second target portion 120 is generally a three-dimensional structure with a certain length, width, and height, and has multiple surfaces. In some embodiments, the second target portion 120 includes a first side surface 121 and a second side surface 122 disposed opposite to the first side surface 121. The first side surface 121 is the side surface of the outer peripheral surface of the second target portion 120 that connects to or is close to the first target portion 110. The outer peripheral surface refers to the surface connecting the first and second surfaces, and is generally formed by multiple side surfaces connected end to end. The distance between the first flash 410 and the first side surface 121 is less than or equal to a first preset value. The first preset value is less than or equal to 1 / 2 of the distance between the first side surface 121 and the second side surface 122. This allows the first flash 410 to be closer to the first target portion 110, and thus closer to the first camera 310, enabling better illumination of the first camera 310.

[0061] Based on the above embodiments, in order to reduce the distance between the first flash 410 and the first camera 310, the range of the first preset value can be further reduced. For example, the first preset value can be less than or equal to 1 / 4, 1 / 10, or the distance between the first side 121 and the second side 122, or the first flash 410 can be connected to the first side 121. This way, compared to a first preset value greater than 1 / 4 or 1 / 10 of the distance between the first side 121 and the second side 122, the first flash 410 can be closer to the first target portion 110, and thus closer to the first camera 310, providing better illumination for the first camera 310.

[0062] Furthermore, for smaller terminals, such as the aforementioned tablet phones and foldable phones, the portion where the first flash 410 is typically located is the part held by the hand. To reduce the risk of the first flash 410 being blocked by the hand when holding the device, in some embodiments, the second target portion 120 includes a third side 123 and a fourth side 124 disposed opposite to the third side 123. The third side 123 is one of the sides of the second target portion 120 that connects the first side 121 and the second side 122, and the fourth side 124 is the side of the second target portion 120 that connects the first side 121 and the second side 122 and is disposed opposite to the third side 123. The distance between the first flash 410 and the third side 123 is less than or equal to a second preset value. The second preset value is less than or equal to half the distance between the third side 123 and the fourth side 124. Using the solution provided in this embodiment, the first flash 410 can be positioned close to the edge of the second target portion 120, reducing the risk of it being blocked by the hand.

[0063] Based on the above embodiments, in order to further reduce the risk of the first flash 410 being blocked by a hand, the range of the second preset value can be further narrowed. For example, the second preset value can be made less than or equal to 1 / 3 or 1 / 4 of the distance between the third side 123 and the fourth side 124 of the second target part 120.

[0064] In some embodiments, the first flash 410 is located in the corner area b near the junction of the first side 121 and the third side 123 or the fourth side 124. The range of the corner area b can be set as needed. For example, it can be defined as an area near the connecting line between the first side 121 and the third side 123 or the fourth side 124, and whose area is less than or equal to 1 / 3 or 1 / 4 of the projection area of ​​the second target part on the back of the main body. Regardless of the setting method, placing the first flash 410 in the corner area b formed by the first side 121 and the third side 123 or the fourth side 124 allows the first flash 410 to be positioned close to both ends of the first side 121. This makes it easier for the first flash 410 to be positioned in the gap between the thumb and palm when holding the terminal, which on the one hand does not affect the user experience of holding the terminal, and on the other hand reduces the risk of the first flash 410 being blocked, achieving multiple benefits.

[0065] Since the first camera 310 is generally located on one side of the center line of the first target portion 110, and the first flash 410 is also located on one side of the center line of the second target portion 120, in the above embodiments, the first flash 410 and the first camera 310 can be located on the same side of the main body 100, such as the first flash 410 being located on the left side of the second target portion 120 and the first camera 310 being located on the left side of the first target portion 110, or the first flash 410 being located on the right side of the second target portion 120 and the first camera 310 being located on the right side of the first target portion 110; or they can be located on different sides of the main body 100, such as the first flash 410 being located on the left side of the second target portion 120 and the first camera 310 being located on the right side of the first target portion 110, or the first flash 410 being located on the right side of the second target portion 120 and the first camera 310 being located on the left side of the first target portion 110. Understandably, when the first flash 410 and the first camera 310 are located on the same side of the main body 100, the distance between them is relatively close, and the first flash 410 provides better fill light for the first camera 310.

[0066] Since the first circuit board 510 typically houses a main chip such as a System-on-a-Chip (SoC), which sends control signals to the second circuit board 520, the second circuit board 520 is generally communicatively connected to the first circuit board 510. This communication connection can be achieved through an electrical connector linking the second circuit board 520 and the first circuit board 510, or through a wireless connection method such as a wireless communication module. In some embodiments, to ensure stable signal connection between the first circuit board 510 and the second circuit board 520, they are connected via a first electrical connector 530. The first electrical connector 530 may include a flexible circuit board 541, wires, etc.

[0067] In related technologies, the first flash 410 and the first camera 310 are connected to the same circuit board. However, the terminal provided in this application not only changes the setting position of the first flash 410, but also changes the electrical connection scheme of the first flash 410. As shown in Figures 8 and 9, Figure 9 is a schematic diagram of the internal structure of a terminal provided in another embodiment of this application. The first flash 410 is connected to the second circuit board 520. Specifically, there can be multiple connection methods between the first flash 410 and the second circuit board 520. As shown in Figure 8, in some embodiments, the first flash 410 is electrically connected to the second circuit board 520 through a second electrical connector 540. As shown in Figure 9, in other embodiments, the first flash 410 is electrically connected to a first electrical connector 530. The structures of the first electrical connector 530 and the second electrical connector 540 can be the same or different, and both can include a flexible circuit board 541, wires, etc. When the first flash 410 is electrically connected to the first electrical connector 530, it can be directly soldered or connected with the aid of a third electrical connector 550. When the first flash unit 410 is directly soldered to the first electrical connector 530, there is no need to add a separate adapter connector for the first flash unit 410, resulting in fewer components within the terminal. The structure of the third electrical connector 550 can be the same as or different from the structure of the first electrical connector 530 or the second electrical connector 540, depending on the usage requirements. Regardless of the connection method used, the first flash unit 410 can be electrically connected to a nearby circuit board (i.e., the second circuit board 520). Thus, in the case of a foldable terminal structure, it is only necessary to set the first electrical connector 530 through the shaft (i.e., through the aforementioned pivot), without needing to set the electrical connectors between the first flash unit 410 and the second circuit board 520 (including the second electrical connector 540 in Figure 8 and the third electrical connector 550 in Figure 9) through the shaft, which can reduce the risk of damage to these electrical connectors to a certain extent. In addition, the arrangement of the second electrical connector 540 and the third electrical connector 550 allows the location of the first flash 410 to be unrestricted by the location of the first electrical connector 530, making the design and installation of the first flash 410 more convenient.

[0068] In some embodiments, the second electrical connector 540 is spaced apart from the first electrical connector 530. Since the terminal typically also includes a battery, and at least a portion of the first electrical connector 530 is stacked with the battery, the thickness of the area corresponding to the terminal and the first electrical connector 530 is relatively large. The spaced arrangement of the second electrical connector 540 from the first electrical connector 530 prevents the second electrical connector 540 from overlapping with the first electrical connector 530, thus ensuring that the arrangement of the second electrical connector 540 does not adversely affect the thickness of the terminal.

[0069] In the above embodiments, the terminal may or may not include a battery 600. When the terminal includes a battery 600, there may be one or more batteries 600. When there are multiple batteries 600, they may be disposed on one part or on multiple parts, depending on the usage requirements.

[0070] As shown in Figure 10, which is a schematic diagram of the internal structure of a terminal provided in another embodiment of this application, a battery 600 is disposed on a second target portion 120 and electrically connected to a first circuit board 510 and / or a second circuit board 520 to supply power to both. A gap 610 exists between the battery 600 and the edge of the second target portion 120, and at least a portion of the aforementioned second electrical connector 540 is located within the gap 610. It is understood that the gap 610 can be a regular shape or an irregular shape, specifically determined according to the shape of the battery 600 and the edge shape of the second target portion 120. The fact that at least a portion of the aforementioned second electrical connector 540 is located within the gap 610 ensures that the thickness of the assembly of the battery 600 and the second electrical connector 540 is comparable to the thickness of the battery 600, preventing an increase in the thickness of the corresponding area of ​​the battery 600 due to the placement of the second electrical connector 540, thus resulting in a smaller terminal thickness.

[0071] In some embodiments, the terminal further includes a battery protection board 620. The battery protection board has at least a first portion and a second portion. The first portion of the battery protection board is located within the gap and connected to the second target portion, while the second portion of the battery protection board contacts the battery to secure it to the second target portion. That is, the battery 600 is fixedly contacted to the frame of the second target portion 120 via the battery protection board 620, with a portion of the battery protection board 620 located within the aforementioned gap 610. At least a portion of the second electrical connector 540 is stacked on top of the first portion. That is, a portion of the second electrical connector 540 can be stacked on the battery protection board 620, thus making efficient use of the space within the aforementioned gap, resulting in a compact internal structure for the terminal and facilitating miniaturization design.

[0072] In some embodiments, the battery 600 is electrically connected to the second circuit board 520 via a fourth electrical connector 630, which may include a circuit board, wires, etc. The fourth electrical connector 630 may be partially located within the aforementioned gap 610 and partially located on the second circuit board 520, or partially located on the battery 600 and partially located on the second circuit board 520, or other configurations may be employed. To make efficient use of the internal space of the terminal, at least a portion of the second electrical connector 540 may be stacked with at least a portion of the fourth electrical connector 630, i.e., both may be at least partially stacked. For example, a portion of the second electrical connector 540 above the second circuit board 520 may be stacked with a portion of the fourth electrical connector 630 above the second circuit board 520, or a portion of the second electrical connector 540 within the gap 610 may be stacked with a portion of the fourth electrical connector 630 within the gap 610. This allows for a compact internal structure of the terminal, facilitating miniaturization design.

[0073] In some embodiments, the fourth electrical connector 630 includes a flexible circuit board 541, at least a portion of which is located within the gap 610. The flexible circuit board 541 can be connected to the second circuit board 520 by soldering, or by means of a spring clip 542, connector, etc., depending on the application requirements. Another portion of the second electrical connector 540 (such as the portion near the second circuit board 520) can be stacked with the fourth electrical connector 630, thereby allowing the second electrical connector to avoid protruding structures such as screws on the second circuit board 520. By adopting the above solution, the risk of the second electrical connector 540 stacking with the first electrical connector 530 can be reduced, as can the risk of the second electrical connector 540 stacking with protruding structures can be reduced, thereby reducing the risk of increased terminal thickness due to the installation of the second electrical connector 540.

[0074] In the above embodiments, the first electrical connector 530, the second electrical connector 540, and the fourth electrical connector 630 may each include a flexible circuit board, so that the bending of the above electrical connectors can be reduced according to the installation needs during installation, so as to meet the usage needs of different installation environments, and can improve the installation speed of the above electrical connectors to a certain extent.

[0075] As shown in Figure 11, Figure 11 is a control principle diagram of the terminal provided in the embodiments of this application. To improve the intelligence level of the terminal provided in the above embodiments, in some embodiments, the terminal further includes a photosensitive component. The photosensitive component may include one or more photosensitive modules 700, wherein at least one photosensitive module 700 is correspondingly configured with the first camera 310 and is used to detect the ambient brightness on the light-incident side of the first camera 310. Other photosensitive modules 700 may be correspondingly configured with other cameras. The photosensitive module 700 may include a brightness sensor or the like capable of detecting ambient brightness. The photosensitive module 700 corresponding to the first camera 310 may be disposed on the first target portion 110, or on the second target portion 120, or integrated into the first camera 310, the first flash 410, or the first screen.

[0076] At least one of the first circuit board 510 and the second circuit board 520 is provided with a control module 800. The control module 800 can be a single electronic component such as a SOC chip or CPU, or it can be composed of multiple electronic components. The control module 800 receives signals output by the photosensitive module 700 and controls the first screen and / or the first flash 410 to illuminate based on the signals output by the photosensitive module 700, thereby providing supplementary lighting for the first camera 310. Specifically, the photosensitive module 700 can directly output the detection result (i.e., ambient brightness), which can be output as an electrical signal. Alternatively, the photosensitive module 700 can also output electrical or optical signals related to the detection result. The control module 800 then analyzes these electrical or optical signals to derive the detection result and controls the first screen and / or the first flash 410 to illuminate based on the detection result.

[0077] The control module 800 can be a module whose function can be changed by writing a program. In this way, the function of the control module 800 can be set according to usage needs. Alternatively, the program can be fixed during the design of the control module 800, so that the control module 800 can only implement preset functions. For example, the control module 800 can be set to: when the photosensitive module 700 detects that the ambient brightness is lower than a first preset value but higher than a second preset value, control the first screen to light up, thereby providing supplementary lighting for the first camera 310; when the photosensitive module 700 detects that the ambient brightness is lower than a second preset value but higher than a third preset value, control the first flash 410 to light up, thereby providing supplementary lighting for the first camera 310; when the photosensitive module 700 detects that the ambient brightness is lower than a third preset value, control both the first screen and the first flash 410 to light up, thereby providing supplementary lighting for the first camera 310. The first, second, and third preset values ​​decrease sequentially.

[0078] By adopting the above scheme, the terminal can not only provide supplementary lighting for the first camera 310 through the first flash 410, but also provide supplementary lighting for the first camera 310 through the first screen. Furthermore, different supplementary lighting schemes can be implemented through the cooperation of the photosensitive module 700 and the control module 800 to meet the needs of capturing images through the first camera 310 under different ambient brightness conditions.

[0079] To further enhance the intelligence of the terminal, in some embodiments, the control module 800 can not only control the first screen to light up based on the data acquired by the photosensor module 700, but also control the first screen to switch between at least two brightness levels based on the aforementioned data. For example, assuming a fourth preset value exists between the first and second preset values, when the photosensor module 700 detects that the ambient brightness is lower than the first preset value but greater than the fourth preset value, it controls the first screen to light up at the first brightness level, thereby providing supplementary lighting for the first camera 310; when the photosensor module 700 detects that the ambient brightness is lower than the fourth preset value but greater than the second preset value, it controls the first screen to light up at the second brightness level, thereby providing supplementary lighting for the first camera 310. The second brightness level is greater than the first brightness level. This allows the terminal to control the brightness of the first screen according to the ambient brightness, thereby providing supplementary lighting for the first camera 310 to meet the shooting needs in different environments, reducing unnecessary energy waste, and minimizing the risk of overexposure during shooting.

[0080] In some embodiments, the first screen is used to display a preset image to provide supplementary lighting for the first camera 310 when it is in operation. The preset image can be any image with high brightness, as long as its brightness is sufficient to provide supplementary lighting for the first camera 310. By adopting this approach, the brightness of the first screen can be relatively high when providing supplementary lighting for the first camera 310, thereby achieving the supplementary lighting effect.

[0081] In some embodiments, the preset screen is a white screen. The brightness of a white screen is generally higher than that of other screens. Using a white screen as the preset screen can make the brightness of the first screen higher, so as to meet the supplementary lighting needs.

[0082] In some embodiments, multiple parts are sequentially rotated and connected. This allows the terminal to be foldable, enabling the terminal's state to be changed according to usage needs to meet different requirements.

[0083] In some embodiments, the camera assembly 300 further includes a second camera 320. The second camera 320 and the second screen are disposed on the same side of the main body 100. The second camera 320 is electrically connected to either the first circuit board 510 or the second circuit board 520. The structure of the second camera 320 may be the same as or different from that of the first camera 310, depending on the usage requirements. The second camera 320 can capture images in front of the second screen, thus, in conjunction with the first camera 310, enabling the terminal to capture images from both sides, meeting different usage needs.

[0084] In some embodiments, the flash assembly 400 further includes a second flash 420. The second flash 420 is located on the same side of the main body 100 as the second camera 320 and is used to provide supplemental lighting for the second camera 320. The second flash 420 is electrically connected to either the first circuit board 510 or the second circuit board 520.

[0085] The structure and setting of the second flash 420 can be the same as or different from that of the first flash 410. For example, the second flash 420 can be set on a different part from the second camera 320; or it can be set adjacent to the second camera 320, with both set on the same part (such as the first target part 110).

[0086] The second flash 420 allows the second camera 320 to take pictures even in low-light conditions, meeting the user's needs.

[0087] In the above embodiments, the terminal screen packaging technology can employ COG (Chip On Glass, where the IC chip is directly bonded to the glass surface of the LCD (Liquid Crystal Display) screen), COF (Chip On Flex or Chip On Film), and COP (Chip On Pi, where a portion of the screen is bent and then packaged, integrating the screen cabling and IC (Integrated Circuit) chip beneath the screen) packaging, etc. It is understood that the terminal configuration methods provided in the above embodiments can be applied to flexible screen projects using COP packaging (such as single-curved, double-curved, triple-curved, quadruple-curved, flat, foldable, hinged screens, etc.).

[0088] It is understood that the terminal provided in this application embodiment is not only applicable to terminals with a small rear screen, but also to terminals with screens on both large sides, one of which (such as the front of the terminal) has a small screen, and also to terminals with only one screen, which is located in one part of the terminal, such as mobile phones for the elderly.

[0089] Finally, it should be noted that the above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
