Description

Technical Field

[0001] This application relates to the field of foldable display technology, and more particularly to a display terminal. Background Technology

[0002] With the continuous development of communication technology, foldable display terminals are gradually becoming a development trend for future mobile electronic products. When unfolded, foldable display terminals offer a larger display area, enhancing the viewing experience. When folded, they are also convenient for users to carry. However, folded display terminals are relatively thick, resulting in a less comfortable grip. Summary of the Invention

[0003] This application provides a display terminal to address the problem of a large thickness and poor grip experience when the display terminal is in a folded state.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] One aspect of this application provides a display terminal, including a first hinge mechanism, a first housing, a second housing, a second hinge mechanism, and a third housing. Furthermore, the display terminal also includes a first battery and a second battery. The second housing and the first housing are respectively located on opposite sides of the first hinge mechanism, and the second housing and the first housing are rotatably connected via the first hinge mechanism. The third housing and the second housing are respectively located on opposite sides of the second hinge mechanism, and the third housing and the second housing are rotatably connected via the second hinge mechanism. When the display terminal is in a flattened state, when the user folds the display terminal, the second housing and the first housing rotate relative to each other, and the second housing and the third housing rotate relative to each other, allowing the third housing to flip onto top of the second housing, and the first housing to flip onto top of the third housing. Thus, when the display terminal is in a closed state, the third housing is located between the first housing and the second housing, and the display terminal can be folded into a "G" shape. Furthermore, in the first housing, the second housing, and the third housing, the average thicknesses of two of the housings are H1 and H2, respectively, and the average thickness of the other housing is H3, where H3 < H1 and H3 < H2. The first battery and the second battery are respectively located within the housing with an average thickness of H1 and the housing with an average thickness of H2. Since the battery is one of the thickest components in a display terminal, the thickness of the casing containing the battery is limited, resulting in a smaller reduction in thickness. In this case, when the average thickness of the casing is relatively small, for example, when the battery is not located in the third casing, it is beneficial to minimize the average thickness of the third casing, thereby reducing the overall thickness of the display terminal and improving the user's grip.

[0006] In one optional embodiment, the average thickness of the first housing is H1, the average thickness of the second housing is H2, and the average thickness of the third housing is H3. In this case, the thicker second housing is located between the first and third housings. When the housing materials include metal, the heat generated by the internal components of the second housing can also be dissipated simultaneously through the first and third housings on both sides, increasing the heat dissipation pathways of the second housing and improving the heat dissipation efficiency of the internal components. Furthermore, the thicker second housing allows for more components to be housed, resulting in a heavier second housing compared to the third housing. Therefore, the heavier second housing is located between the first and third housings. This also allows the center of gravity of the display terminal to be located in the middle of the display terminal in its flattened state, thereby improving the stability of the display terminal during use.

[0007] In one alternative embodiment, the average thickness of the first housing is H1, the average thickness of the second housing is H3, and the average thickness of the third housing is H2. In this case, the thinner second housing is located between the first and third housings.

[0008] In one optional embodiment, the width of either the first housing or the second housing is greater than the width of the third housing. The width direction refers to the direction in which the first housing points towards the third housing, or vice versa, when the display terminal is in its flattened state. This way, when the display terminal is in its closed state, the end of the third housing located between the first and second housings that faces away from the second pivot mechanism—that is, the right end of the third housing—can have a certain gap with the first pivot mechanism. This reduces the probability of the third housing colliding with the first display screen during folding. Furthermore, this gap also makes it easier for the portion of the first display screen covering the first pivot mechanism to bend, ultimately making it easier for the display terminal to bend into its closed state.

[0009] In one optional embodiment, the display terminal further includes a first display screen. The first display screen includes a first display section, a second display section, a third display section, a first bending section, and a second bending section. The first bending section is connected between the first and second display sections, and the second bending section is connected between the second and third display sections. The first display section covers a first housing, the first bending section covers a first pivot mechanism, the second display section covers a second housing, the second bending section covers a second pivot mechanism, and the third display section covers a third housing. When the display terminal is in a closed state, the first and second bending sections can undergo flexible deformation and bend, allowing the first display screen to fold and flatten simultaneously with the display terminal during folding and flattening.

[0010] In one optional embodiment, when the display terminal is in the closed state, the first display unit is located between the first housing and the third housing, and the second and third display units are located between the third housing and the second housing. In this way, when the display terminal is in the closed state, the first display screen is enclosed within a folding device composed of the first housing, the second housing, the third housing, the first pivot mechanism, and the second pivot mechanism. This folding device can protect the first display screen from impacts.

[0011] In one optional embodiment, the display terminal further includes a first camera, a portion of which is disposed within a second housing. The second housing has a first lens aperture, which exposes the light-receiving surface of the first camera. A portion of the first camera can extend beyond the first lens aperture so that the light-receiving surface of the first camera can be exposed within the second housing, thereby ensuring that external light can pass through the first lens aperture and enter the first camera. Furthermore, when the display terminal is in a closed state, the first lens aperture is located on the side of the second housing facing away from the third housing. In this way, when the display terminal is in a closed state, a portion of the first camera can extend beyond the first lens aperture in a direction away from the third housing, thereby preventing interference between the positions of the first camera and the third housing when the display terminal is in a closed state.

[0012] In one optional embodiment, the display terminal further includes a second display screen that covers the first housing. When the display terminal is in a closed state, the second display screen is located on the side of the first housing opposite to the third housing. In this way, the second display screen can serve as the outer screen of the display terminal. When the display terminal is in a closed state, the display surface of the second display screen can be part of the outer surface of the display terminal, thereby enabling image display through the second display screen when the display terminal is in a closed state.

[0013] In one optional embodiment, the display terminal further includes a second camera, a portion of which is disposed within the first housing. The first housing has a second lens aperture, which exposes the light-receiving surface of the second camera, thereby ensuring that external light can pass through the second lens aperture and enter the second camera. Furthermore, when the display terminal is in a closed state, the second lens aperture is located on the side of the first housing facing away from the third housing. This allows a portion of the second camera to extend out of the second lens aperture in the direction away from the third housing when the display terminal is closed, thus preventing interference between the second camera and the third housing when the display terminal is closed.

[0014] In one optional embodiment, the display terminal further includes a third display screen that covers the second housing. When the display terminal is in a closed state, the third display screen is located on the side of the second housing opposite to the second housing. In this way, the second display screen can serve as the outer screen of the display terminal. When the display terminal is in a closed state, the display surface of the second display screen can be part of the outer surface of the display terminal, thereby enabling the display terminal to display images through the second display screen when it is in a closed state.

[0015] In one optional embodiment, when the display terminal is in a closed state, the first display unit is located on the side of the first housing opposite to the third housing, the second display unit is located on the side of the second housing opposite to the third housing, and the third display unit is located between the third housing and the first housing. In this way, when the display terminal is in a closed state, the first and second display units can serve as an external screen for the display terminal, thus eliminating the need for a separate external screen.

[0016] In one optional embodiment, when the average thickness of the first housing is H1, the average thickness of the second housing is H2, and the average thickness of the third housing is H3, the display terminal further includes a first circuit board and a second circuit board. The first circuit board is located inside the first housing, and the second circuit board is located inside the second housing. In this way, by respectively placing the first and second circuit boards inside the first and second housings, it is possible to eliminate the need for circuit boards in housings with an average thickness of H3, such as the third housing, thereby making it easier to reduce the thickness of housings with an average thickness of H3, such as the third housing.

[0017] In one optional embodiment, when the average thickness of the first housing is H1, the average thickness of the second housing is H3, and the average thickness of the third housing is H2, the display terminal further includes a first circuit board and a second circuit board. The first circuit board is located inside the first housing, and the second circuit board is located inside the third housing. The technical advantage of eliminating the need for a circuit board in a housing with an average thickness of H3, such as the second housing, is similar and will not be elaborated further here.

[0018] In one optional embodiment, when H2 > H1, the first battery is located inside the first housing, and the second battery is located inside the second housing, with the second battery being thicker than the first battery. This minimizes the average thickness of the first housing, thus facilitating a reduction in the overall thickness of the display terminal. Because the second battery is thicker, its capacity can be greater than that of the first battery, allowing it to store more power. Since the thicker second battery is located inside the second housing, which is situated between the first and third housings, and if the housing material includes metal, the second housing can dissipate heat generated by the second battery through the first and third housings located on either side of it. This increases the heat dissipation pathways of the second housing, improves its heat dissipation efficiency, and reduces the likelihood of the second battery overheating. This approach allows the second battery to have a higher capacity while reducing the likelihood and duration of overheating, thereby extending the lifespan of both the battery and the display terminal.

[0019] In one optional embodiment, the third housing includes a first end and a second end, the first end being close to the second housing and the second end being away from the second housing; the thickness of the first end is greater than the thickness of the second end. In its flattened state, the display terminal has a display surface and a back surface disposed opposite to each other; the surfaces of the first housing, the second housing, and the third housing are flush on the side where the display surface is located, and the surface of the third housing on the side where the back surface is located is a first inclined surface, and the third housing can be a wedge-shaped structure. In this case, the thickness of the first end of the third housing can be the same as or approximately the thickness of the end of the second housing facing the third housing. In this way, the second pivot mechanism located between the second housing and the third housing can have a larger layout space along the thickness direction of the display terminal, thereby making it easier to meet design requirements for the mechanical properties of the second pivot mechanism, such as strength or stiffness, and reducing the design difficulty of the second pivot mechanism.

[0020] In one optional embodiment, the surface of the second housing on the side containing the back is a second inclined surface, and the slopes of the first and second inclined surfaces are the same. Because the second housing has a second inclined surface, the second housing, as a wedge-shaped structure, can be of unequal thickness, thereby reducing the thickness of the end of the second housing facing the third housing, thus reducing the overall weight and meeting the design requirements for lightweight products. Furthermore, since the slopes of the first and second inclined surfaces of the third housing are the same, the junction between the first and second inclined surfaces is smooth, increasing user comfort when holding the device. Alternatively, in other embodiments, the slopes of the first and second inclined surfaces may be different; this application does not limit this.

[0021] In one optional embodiment, when H2 > H1, the first housing includes a third end and a fourth end, the third end being close to the second housing and the fourth end being away from the second housing, with the thickness of the third end being greater than the thickness of the fourth end. The surface of the first housing on the side where the back is located is a third inclined surface. In this case, the thickness of the third end of the first housing can be the same as or only slightly different from the thickness of the end of the second housing facing the first housing. This allows the first pivot mechanism located between the second and first housings to have a larger layout space along the direction of the display terminal, making it easier to meet design requirements for the mechanical properties of the first pivot mechanism, such as strength or stiffness, and thus reducing the design difficulty of the first pivot mechanism.

Detailed Implementation

[0047] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0048] In the following description, the terms "first," "second," etc., are used for descriptive convenience only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

In the accompanying drawings of this application embodiment, components are represented by arrowed guide lines; parts are represented only by guide lines, and hollow structures, such as holes, are represented by arrows with wavy lines.

[0051] This application provides a display terminal that can be applied to various communication systems or protocols, such as Bluetooth (BT) communication technology, Global Positioning System (GPS) communication technology, Wireless Fidelity (WiFi) communication technology, Wideband Code Division Multiple Access (WCDMA) communication technology, Long Term Evolution (LTE), 5G communication technology, and other future communication technologies.

[0052] The display terminal in this application embodiment can be a mobile phone, tablet computer, laptop computer, smart home device, smart wearable device (e.g., smartwatch, smart bracelet, smart glasses, smart helmet), virtual reality (VR) display terminal, augmented reality (AR) display terminal, etc. The display terminal can also be a handheld device with wireless communication capabilities, a computing device, or other processing device connected to a wireless modem, an in-vehicle device, a display terminal in a 5G network, or a display terminal in a future evolved public land mobile network (PLMN), etc., and this application embodiment is not limited to these categories.

[0053] For ease of explanation, the following examples all use a foldable phone as the display terminal. In this case, such as Figure 1As shown, the display terminal 100 may include a display screen, such as a first display screen 10. In some embodiments of this application, the first display screen 10 may be a self-emissive display screen, such as an organic light-emitting diode (OLED) display screen, a micro (or mini) light-emitting diode (LED) display screen, or a quantum dot light-emitting diode (QLED) display screen, etc. Alternatively, in other embodiments of this application, the first display screen 10 may also be a liquid crystal display (LCD) requiring a backlight. The first display screen 10 may include a display surface for displaying images, and the display surface of the first display screen 10 may be the display surface of the display terminal 100.

[0054] Furthermore, the display terminal 100 may also include a processor electrically connected to the first display screen 10. This processor can provide display data to the first display screen 10 to drive the first display screen to display images. For example, the processor may include one or more processing units, such as: an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural network processing unit (NPU). Different processing units may be independent devices or integrated into one or more processors.

[0055] During the process of folding or flattening the display terminal 100, in order to support the aforementioned first display screen 10, the following steps are continued... Figure 1As shown, the display terminal 100 may further include a folding device 20. When the display terminal 100 is in a flattened state, the folding device 20 can support the first display screen. In some embodiments of this application, when the display terminal 100 is a tri-fold display terminal, the folding device 20 may include a first housing 101, a second housing 102, and a third housing 103 arranged sequentially along a first direction X. The first display screen 10 can cover the first housing 101, the second housing 102, and the third housing 103, and the first display screen 10 can be connected to at least one of the first housing 101, the second housing 102, and the third housing 103. In some embodiments, the surfaces of the first housing 101, the second housing 102, and the third housing 103 facing away from the first display screen 10 can be the back of the display terminal 100.

[0056] Furthermore, the first housing 101 and the second housing 102 are rotatably connected, and the third housing 103 and the second housing 102 are rotatably connected, thereby enabling the display terminal 100 to be in a position where... Figure 1 The flattened state is shown. For example, when display terminal 100 is in such a flattened state... Figure 1 In the flattened state shown, the included angle γ between the first housing 101 and the second housing 102, or the included angle β between the second housing 102 and the third housing 103, can be or is approximately 180°. Alternatively, where a certain angular tolerance is allowed, for example, the aforementioned included angle γ or β can also be a value such as 165°, 177°, or 185°. In this case, the surfaces of the first housing 101, the second housing 102, and the third housing 103 facing the first display screen 10 can be on or approximately on the same plane.

[0057] Based on this, in order to allow the first housing 101 and the second housing 102 to rotate relative to each other, and to allow the third housing 103 and the second housing 102 to rotate relative to each other, as follows: Figure 1 As shown, the folding device 20 may further include a first pivot mechanism 21 and a second pivot mechanism 22. The first housing 101 and the second housing 102 may be located on opposite sides of the first pivot mechanism 21, and are rotatably connected to the first pivot mechanism 21, so that the first housing 101 can be rotatably connected to the second housing 102 via the first pivot mechanism 21. Furthermore, a third housing 103 and the second housing 102 are located on opposite sides of the second pivot mechanism 22, and are rotatably connected to the second pivot mechanism 22, so that the third housing 103 can be rotatably connected to the second housing 102 via the second pivot mechanism 22.

[0058] The embodiments of this application do not limit the structure of the first rotating shaft mechanism 21 and the second rotating shaft mechanism 22, as long as it can ensure that the first housing 101 and the second housing 102 are rotatably connected through the first rotating shaft mechanism 21, and the third housing 103 and the second housing 102 are rotatably connected through the second rotating shaft mechanism 22.

[0059] When the display terminal 100 is in such a state Figure 1 In the flattened state shown, when the user needs to fold the display terminal 100, in some embodiments, the third housing 103 can be folded first. For example... Figure 2 As shown, an external force can be applied to the third housing 103, causing the third housing 103 to rotate relative to the second housing 102 via the second rotating shaft mechanism 22. This allows the third housing 103 to be flipped over and placed above the second housing 102, achieving the folding of the third housing 103 and thus placing the third housing 103 and the second housing 102 in a closed state.

[0060] Next, the user Figure 2 An external force is applied to the first housing 101, causing it to rotate relative to the second housing 102 via the first rotating shaft mechanism 21. For example... Figure 3 As shown, the first housing 101 can be flipped over to be above the third housing 103, thus folding the first housing 101 and placing the first housing 101 and the third housing 103 in a closed state. When the display terminal 100 is in the closed state, the second housing 102, the third housing 103, and the first housing 101 are stacked, with the third housing 103 located between the second housing 102 and the first housing 101. At this time, the display terminal 100 can be folded into a "G" shape.

[0061] In this embodiment, the included angle between two shells in a closed state, such as the third shell 103 and the second shell 102, can be 0°. Alternatively, if a certain angular tolerance is allowed, the included angle between the two shells in a closed state can also be 2° or 5°, etc.

[0062] To illustrate the positional relationships of the various components in the display terminal 100, an XYZ coordinate system is established in the accompanying drawings. For example, the XY plane can be positioned relative to the display terminal 100 as follows: Figure 1 In the flattened state shown, the display surface (the surface used to display images) of the first display screen 10 is parallel. Here, the X direction can be such that the display terminal 100 is in a position as... Figure 1 The first housing 101, the second housing 102, and the third housing 103 are arranged sequentially in the flattened state shown. The Y direction can be aligned with... Figure 1The extension directions of the first rotating shaft mechanism 21 or the second rotating shaft mechanism 22 are parallel. That is, when the first housing 101 rotates relative to the second housing 102, the Y direction can be parallel to the direction of the rotation center of the first housing 101. Similarly, when the third housing 103 rotates relative to the second housing 102, the Y direction can be parallel to the direction of the rotation center of the third housing 103.

[0063] Furthermore, the Z direction can be such that the first housing 101, the second housing 102, and the third housing 103 are located in the same position. Figure 3 In the closed state shown, the stacking direction of the first housing 101, the second housing 102, and the third housing 103 is as follows. That is, the Z direction can be the thickness direction of the display terminal 100 or the aforementioned housings. Any two of the X, Y, and Z directions are perpendicular.

[0064] The above example illustrates the display terminal 100 as comprising three sequentially adjacent housings, such as a first housing 101, a second housing 102, and a third housing 103. This application does not limit the number of housings or the number of hinge mechanisms in the folding device 20, as long as it includes at least three sequentially adjacent housings (e.g., a first housing 101, a second housing 102, and a third housing 103), and there is a hinge mechanism between any two adjacent housings. For ease of explanation, the following examples all use the display terminal 100 comprising a first housing 101, a second housing 102, and a third housing 103 as an example.

[0065] In some embodiments of this application, such as Figure 4 (for the following) Figure 1 As shown in the schematic diagram obtained from A1 in the above-mentioned first shell 101, second shell 102 and third shell 103, the average thicknesses of two shells are H1 and H2, respectively, and the average thickness of the other shell is H3, where H3 < H1 and H3 < H2. In this way, the average thickness of one of the shells 101, 102 and 103 can be less than the average thickness of the other two shells.

[0066] For example, such as Figure 4As shown, the average thickness of the first housing 101 can be H1, the average thickness of the second housing 102 can be H2, and the average thickness of the third housing 103 can be H3. Based on this, among the first housing 101, the second housing 102, and the third housing 103, the average thickness of the third housing 103 (e.g., H3) is the smallest. In this case, the second housing 102, with a larger thickness relative to the third housing 103, is located between the first housing 101 and the third housing 103. When the materials of the housings include metallic materials, the heat generated by the internal components of the second housing 102 can also be dissipated through the first housing 101 and the third housing 103 on both sides, increasing the heat dissipation pathways of the second housing 102 and improving the heat dissipation efficiency of the internal components.

[0067] Furthermore, compared to the third housing 103, the thicker second housing 102 can accommodate more components, resulting in a greater weight for the second housing 102 compared to the third housing 103. Therefore, the heavier second housing 102 is positioned between the first housing 101 and the third housing 103. This also allows the center of gravity of the display terminal 100 to be located in the middle of the display terminal 100 in its flattened state, thereby improving the stability of the display terminal 100 during use.

[0068] In this embodiment, to improve the support effect of the aforementioned housings on the first display screen 100 when the display terminal 100 is in a flattened state, the first housing 101, the second housing 102, and the third housing 103 are flush with the surfaces on the side where the display surface of the display terminal 100 is located. That is, the first housing 101, the second housing 102, and the third housing 103 are flush with the surface (e.g., the upper surface) of the first display screen 10. Furthermore, the surfaces of the first housing 101, the second housing 102, and the third housing 103 facing the first display screen 10 can be or approximately planar. In this way, the first display screen 10 is subjected to uniform force when flattened, reducing the probability of deformation of the portions of the first display screen 10 covering the first housing 101, the second housing 102, and the third housing 103, and improving the service life of the first display screen 10.

[0069] Furthermore, in the embodiments of this application, the average thickness of the shell refers to, in some embodiments, such as Figure 4 As shown, any one of the first housing 101, the second housing 102, and the third housing 103, whose surface (e.g., the lower surface) facing away from the first display screen 10 can be or approximately planar. In this case, the thickness of any one of the first housing 101, the second housing 102, and the third housing 103 is equal everywhere. Therefore, the average thickness of the housing is the thickness of the housing at any location.

[0070] Alternatively, in other embodiments, such as Figure 5(for the following) Figure 1 As shown in another schematic diagram (A1 in the diagram), the third housing 103 may include a first end a1 and a second end a2. When the display terminal 100 is in a flattened state, the first end a1 is close to the second housing 102, and the second end a2 is away from the second housing 102. The thickness h01 of the first end a1 of the third housing 103 is greater than the thickness h02 of the second end a2 of the third housing 103, that is, h01 > h02. In this case, the surface of the third housing 103 on the side where the back of the display terminal 100 is located (e.g., the surface away from the first display screen 10) is a first inclined surface S1, and the third housing 103 may be a wedge-shaped structure.

[0071] In this case, the average thickness of the wedge-shaped third shell 103 refers to the average thickness of the third shell 103 measured at different locations along the X direction. For example, the average thickness of the third shell 103 can be the average of the thickness h01 at the first end a1 and the thickness h02 at the second end a2. Alternatively, the thickness at the location between the first end a1 and the second end a2 of the third shell 103 can be measured, and the average of this thickness with the thickness h01 and the thickness h02 can be calculated as the average thickness of the third shell 103. This application does not limit the location or number of measurements when calculating the average thickness of the wedge-shaped shell. The above is an example of the average thickness of the shell using the third shell 103 as an example. The average thickness of the first shell 101 and the second shell 102 can be obtained similarly and will not be described in detail here.

[0072] In the third shell 103 Figure 5 In the case of the wedge-shaped structure shown, the thickness h01 of the first end a1 of the third housing 103 can be the same as or approximately the thickness of the end of the second housing 102 facing the third housing 103. In this way, the second rotating shaft mechanism 22 located between the second housing 102 and the third housing 103 can have a larger layout space along the Z direction, making it easier to meet design requirements for the mechanical properties of the second rotating shaft mechanism 22, such as strength or stiffness, and thus reducing the design difficulty of the second rotating shaft mechanism 22.

[0073] Figure 5 This example illustrates the concept using the third housing 103 as an example of a wedge-shaped structure. In other embodiments of this application, such as... Figure 6 (for the following) Figure 1As shown in another schematic diagram obtained from A1 in the diagram, the second housing 102 can also be a wedge-shaped structure. In this case, the surface of the second housing 102 on the side where the back of the display terminal 100 is located (e.g., the surface facing away from the first display screen 10) can be a second inclined surface S2, and the slopes of the first inclined surface S1 and the second inclined surface S2 are the same.

[0074] In this way, since the second housing 102 has a second inclined surface S2, the second housing 102, as a wedge-shaped structure, can be configured with unequal thickness, thereby reducing the thickness of the end of the second housing 102 facing the third housing 103, and thus reducing the overall weight of the device, achieving the design requirement of lightweighting. Furthermore, since the first inclined surface S1 of the third housing 103 and the second inclined surface S2 of the second housing 102 have the same slope, the junction of the first inclined surface S1 and the second inclined surface S2 can be smooth, increasing user comfort when holding the device. Alternatively, in some embodiments, the slopes of the first inclined surface S1 and the second inclined surface S2 may be different; this application does not limit this.

[0075] In addition, such as Figure 4 or Figure 5 As shown, the display terminal 100 may further include a first battery 31 and a second battery 32. The first battery 31 and the second battery 32 may be located within a housing with an average thickness of H1 and an average thickness of H2, respectively. For example, the first battery 31 may be located within the first housing 101, and the second battery 32 may be located within the second housing 102. In this way, the housing with an average thickness of H3 in the display terminal 100, that is, the housing with the smallest average thickness among the three housings (e.g., the first housing 101, the second housing 102, and the third housing 103), such as the third housing 103, may not require a battery.

[0076] Since the battery is one of the thickest components in the display terminal 100, the thickness of the casing containing the battery is limited by the battery's thickness, resulting in a smaller reduction in thickness. In this case, when the casing with an average thickness of H3, such as the third casing 103, does not contain a battery, it is beneficial to minimize the average thickness of the third casing 103, thereby reducing the overall thickness of the display terminal 100 and improving the user's grip.

[0077] This application does not limit the magnitude relationship between the average thickness (e.g., H1) of the first housing 101 and the average thickness (e.g., H2) of the second housing 102. For example, as Figure 4 or Figure 5 As shown, the average thickness (e.g., H2) of the second housing 102 can be greater than the average thickness (e.g., H1) of the first housing 101, i.e., H2 > H1.

[0078] For example, such as Figure 5 As shown, when H2 > H1, the thickness d2 of the second battery 32 located inside the second housing 102 can be greater than the thickness d1 of the first battery 31 located inside the first housing 101, i.e., d2 > d1. In this way, the average thickness of the first housing 101 can be reduced as much as possible, which is beneficial to reducing the overall thickness of the display terminal 100.

[0079] Furthermore, due to the greater thickness d2 of the second battery 32, its capacity can be greater than that of the first battery 31, allowing it to store more electrical energy. Since the thicker second battery 32 can be located within the second housing 102, which is situated between the first housing 101 and the third housing 103, and assuming the housing is made of metal, the second housing 102 can dissipate heat generated by the second battery 32 through the first housing 101 and the third housing 103 located on either side of it. This increases the heat dissipation pathways of the second housing 102, improves its heat dissipation efficiency, and reduces the likelihood of the second battery 32 overheating. In this way, the second battery 32 can have a higher capacity while reducing the likelihood and duration of overheating, thus extending the lifespan of both the battery and the display terminal 100.

[0080] Furthermore, when H2 > H1, such as Figure 6 As shown, the first housing 101 can also be a wedge-shaped structure. The first housing 101 may include a third end a3 and a fourth end a4. The third end a3 is close to the second housing 102, and the fourth end a4 is away from the second housing 102. The thickness h03 of the third end a3 can be greater than the thickness h04 of the fourth end a4. The surface of the first housing 101 on the side where the back of the display terminal 100 is located (e.g., the surface away from the first display screen 10) can be a third inclined surface S3, and the first housing 101 is a wedge-shaped structure.

[0081] Based on this, when the first housing 101 is a wedge-shaped structure, the process continues as follows: Figure 6 As shown, the thickness h03 of the third end a3 of the first housing 101 can be the same as or only slightly different from the thickness of the end of the second housing 102 facing the first housing 101. In this way, the first rotating shaft mechanism 21 located between the second housing 102 and the first housing 101 can have a larger layout space along the Z direction, making it easier for the mechanical properties of the first rotating shaft mechanism 21, such as strength or stiffness, to meet design requirements and reducing the design difficulty of the first rotating shaft mechanism 21.

[0082] The above example illustrates a case where at least one of the two adjacent shells has a wedge-shaped structure, provided that the average thicknesses of the two adjacent shells are unequal. For ease of explanation, the accompanying drawings will assume that the shells have the same thickness at all points when the average thicknesses of the two adjacent shells are unequal.

[0083] Furthermore, the above example illustrates that the average thickness of the second housing 102 (e.g., H2) can be greater than the average thickness of the first housing 101 (e.g., H1), i.e., H2 > H1. In other embodiments, such as Figure 7 (for the following) Figure 1 As shown in the schematic diagram (A1 in the diagram), the average thickness (e.g., H2) of the second housing 102 can be equal to the average thickness (e.g., H1) of the first housing 101, i.e., H2 = H1. Alternatively, for example, the average thickness (e.g., H2) of the second housing 102 can be less than the average thickness (e.g., H1) of the first housing 101, i.e., H2 = H1.

[0084] The following example illustrates how the first battery 31 and the second battery 32 are respectively arranged in the first housing 101 and the second housing 102, assuming that the average thickness of the second housing 102 (e.g., H2) can be greater than the average thickness of the first housing 101 (e.g., H1), i.e., H2 > H1. Figure 8 As shown, the first housing 101 may include a first rear housing 1011 and a first middle frame 1012, with the first rear housing 1011 fastened to the side of the first middle frame 1012 facing away from the first display screen 10. A receiving cavity for accommodating the first battery 31 may be formed between the first rear housing 1011 and the first middle frame 1012. Alternatively, as another example, the first housing 101 may only include the first rear housing 1011, which may form a receiving cavity for accommodating the first battery 31 between itself and the first display screen 10.

[0085] In addition, such as Figure 8 As shown, the second housing 102 may include a second rear housing 1021 and a second middle frame 1022, with the second rear housing 1021 disposed on the side of the second middle frame 1022 facing away from the first display screen 10. A receiving cavity for accommodating the second battery 32 may be formed between the second rear housing 1021 and the second middle frame 1022. Alternatively, the second housing 102 may only include the second rear housing 1021, which may form a receiving cavity for accommodating the second battery 32 between itself and the first display screen 10. The aforementioned receiving cavity may be a closed receiving cavity or a partially closed receiving cavity, and this application does not limit this.

[0086] Continue as Figure 8As shown, the third housing 103 may include a third rear housing 1031 and a third middle frame 1032, with the third rear housing 1031 disposed on the side of the third middle frame 1032 facing away from the first display screen 10. Since no battery is disposed between the third rear housing 1031 and the third middle frame 1032, the thickness of the third housing 103 can be reduced by decreasing the distance between the third rear housing 1031 and the third middle frame 1032 along the Z-direction. Alternatively, the third housing 103 may consist only of the third rear housing 1031; similarly, the thickness of the third housing 103 can be reduced by decreasing the distance between the third rear housing 1031 and the first display screen 10 along the Z-direction.

[0087] For example, continue as follows Figure 8 As shown, when the first housing 101 includes a first middle frame 1012, the second housing 102 includes a second middle frame 1022, and the third housing 103 includes a third middle frame 1032, the first middle frame 1012 and the second middle frame 1022 can be rotatably connected by a first rotating shaft mechanism 21. The second middle frame 1022 and the third middle frame 1013 can be rotatably connected by a second rotating shaft mechanism 22. Alternatively, as another example, when the first housing 101 includes only a first rear housing 1011, the second housing 102 includes only a second rear housing 1021, and the third housing 103 includes only a third rear housing 1031, the first rear housing 1011 and the second rear housing 1021 can be rotatably connected by a first rotating shaft mechanism 21. The second rear housing 1021 and the third rear housing 1031 can be rotatably connected by a second rotating shaft mechanism 22.

[0088] In addition, continue as Figure 8 The display terminal 100 may further include a first circuit board 41 and a second circuit board 42. The first circuit board 41 may be located within the first housing 101. For example, if the first housing 101 includes a first middle frame 1012 and a first rear housing 1011, the first circuit board 41 may be located within a receiving cavity formed between the first middle frame 1012 and the first rear housing 1011. Alternatively, if the first housing 101 includes a first rear housing 1011, the first circuit board 41 may be located between the first rear housing 1011 and the first display screen 10. The second circuit board 42 may be located within the second housing 102. The arrangement of the second circuit board 42 within the second housing 102 is analogous to the arrangement of the first circuit board 41 within the first housing 101, and will not be described further here.

[0089] in, Figure 8This illustration uses a display terminal 100 comprising a first circuit board 41 and a second circuit board 42 as an example. This application does not limit the number of first circuit boards 41 and second circuit boards 42. For example, the display terminal 100 may include two first circuit boards 41 and two second circuit boards 42. Along the X-direction, the two first circuit boards 41 may be located on the upper and lower sides of the first battery 31, respectively. Along the X-direction, the two second circuit boards 42 may be located on the upper and lower sides of the second battery 32, respectively. For example, either the first circuit board 41 or the second circuit board 42 may be a printed circuit board (PCB) or a flexible printed circuit board (FPCB), and this application does not impose any limitations on this.

[0090] In some embodiments, the first circuit board 41 may be electrically connected to the first battery 31, and the first battery 31 may have a chip for supplying power to the first battery 31. The second circuit board 42 may be electrically connected to the second battery 32, and the second battery 32 may have a chip for supplying power to the second battery 32. Alternatively, in other embodiments, the chips for supplying power to the first battery 31 and the second battery 32 respectively may be disposed on the same circuit board. In addition, the display terminal 100 may also include a speaker, a camera, or other chips (e.g., a central processing chip, an image processing chip, a battery management chip, etc.) disposed on the first circuit board 41 or the second circuit board 42, and the above electronic components may be electrically connected to at least one of the first circuit board 41 or the second circuit board 42.

[0091] In this case, such as Figure 9 (for the following) Figure 8 As shown in the cross-sectional view obtained by cutting along the dashed lines O1-O2, when the average thickness of the first housing 101 can be H1, the average thickness of the second housing 102 can be H2, and the average thickness of the third housing 103 can be H3, and the average thickness of the third housing 103 (e.g., H3) is minimized, by respectively placing the first circuit board 41 and the second circuit board 42 inside the first housing 101 and the second housing 102, it is possible to eliminate the need for circuit boards in the housing with an average thickness of H3, such as the third housing 103, thereby making it more advantageous to reduce the thickness of the housing with an average thickness of H3, such as the third housing 103. Alternatively, in some other embodiments, the circuit board can also be placed inside the housing with an average thickness of H3, such as the third housing 103.

[0092] As can be seen from the above, the display terminal 100 may include a camera, for example, such as Figure 8The first camera 51 is shown. For example, a portion of the first camera 51 is disposed within the second housing 102. For instance, if the second housing 102 includes a second rear housing 1021 and a second middle frame 1022, a portion of the first camera 51 may be disposed within a receiving cavity formed between the second rear housing 1021 and the second middle frame 1022. Alternatively, if the second housing 102 includes a rear housing 1021, a portion of the first camera 51 may be disposed within a receiving cavity formed between the second rear housing 1021 and the first display screen 10.

[0093] For example, such as Figure 10 (for the following) Figure 8 As shown in the top view (A2 in the diagram), the first camera 51 can be stacked on the surface of the second circuit board 42 facing away from the second middle frame 1022. The first camera 51 can be electrically connected to the second circuit board 42, and the second battery 32 can supply power to the first camera 51 through the circuit traces in the second circuit board 42, so that the first camera 51 can take pictures. This application does not limit the number of first cameras 51. Figure 10 This example uses two first cameras 51 as an example. In addition, if the display terminal 100 also includes a speaker 60, the speaker 60 can be located inside the second housing 102, and the speaker 60 can be disposed on the side of the second battery 32 away from the first camera 51, that is, on the lower side of the second battery 32.

[0094] Furthermore, as mentioned above, the first camera 51 can be a rear-facing camera. In this case, in order to enable... Figure 10 The first camera 51 shown can receive light from outside the display terminal 100. In some embodiments, such as... Figure 11 (for the following) Figure 8 As shown in another top view obtained from A2 in the diagram, a first lens hole 201 is provided on the second rear shell 1021 of the second housing 102, penetrating the second rear shell 1021. A portion of the first camera 51 can extend out of the first lens hole 201 so that the first camera 51 (as shown in the diagram) can extend out of the first lens hole 201. Figure 10 The light-incident surface (as shown) can expose the second housing 102, thereby ensuring that external light can pass through the first lens hole 201 and enter the first camera 51.

[0095] In some embodiments, the display terminal may further include a first decorative cover (DECO) 211 disposed over the first lens hole 201. The first DECO 211 has a through hole for at least a portion of the light-incident surface of the first camera 51 to pass through. The first DECO 211 is used to shield the portion of the first camera 51 other than the light-incident surface, as well as components surrounding the first camera 51, to improve the appearance.

[0096] Based on this, when a portion of the first camera 51 is located in the second housing 102, as Figure 12 (for example) Figure 3 As shown in the schematic diagram obtained from direction A3, when the display terminal 100 is in the closed state, the first lens hole 201 is located on the side of the second housing 102 away from the third housing 103. In this way, when the display terminal 100 is in the closed state, a part of the first camera 51 can extend out of the first lens hole 201 in the direction away from the third housing 103, thereby avoiding interference between the positions of the first camera 51 and the third housing 103 when the display terminal 100 is in the closed state.

[0097] Furthermore, in order to make the display terminal 100 easier to bend into a closed state, and to reduce the probability of interference between the third housing 103 and the first display screen 10 when the display terminal 100 is in the closed state, the following steps are continued... Figure 12 As shown, the width of any one of the first housing 101 and the second housing 102 is greater than the width of the third housing 103. For example, the width of the first housing 101 is L1, the width of the second housing 102 is L2, and the width of the third housing 103 is L3, where L1 > L3 and L2 > L3. This application does not limit the size relationship between L1 and L2; L1 and L2 can be the same or different. The width direction of any one of the first housing 101, the second housing 102, and the third housing 103 can be determined by the width of the display terminal 100 within the specified width direction. Figure 11 In the flattened state shown, the first housing 101 points in the direction of the third housing 103, or the third housing 103 points in the direction of the first housing 101, i.e., the X direction.

[0098] In this way, when the display terminal 100 is in the closed state, the end of the third housing 103 located between the first housing 101 and the second housing 102 that faces away from the second pivot mechanism 22, i.e., the right end of the third housing 103 can have a certain gap ΔH with the first pivot mechanism 21, thereby reducing the probability of the third housing 103 colliding with the first display screen 10 during folding. Furthermore, the aforementioned gap ΔH also makes it easier for the portion of the first display screen 10 covering the first pivot mechanism 21 to bend, ultimately making it easier for the display terminal 100 to bend into the closed state.

[0099] The above description uses an example where the display terminal 100 includes a display screen, such as the first display screen 10. In other embodiments of this application, the display terminal 100 may also include, Figure 12The second display screen 11 is shown. The second display screen 11 can cover the first housing 101, and when the display terminal 100 is in the closed state, the second display screen 11 is located on the side of the first housing 101 facing away from the third housing 103. In this way, the second display screen 11 can serve as the outer screen of the display terminal 100. When the display terminal 100 is in the closed state, the display surface of the second display screen 11 can be part of the outer surface of the display terminal 100, thereby allowing the display terminal 100 to display images through the second display screen 11 when closed. The aforementioned second display screen 11 can be an OLED display, a micro-LED display, a QLED display, or an LCD.

[0100] Based on this, when the display terminal 100 is in Figure 11 In the flattened state shown, the second display screen 11 can be located on the same side as the first DECO 211. Furthermore, in some embodiments, a third lens hole 203 can be provided on the second display screen 11, which is used to expose the third camera 53 of the display terminal 100 (e.g., ...). Figure 10 (As shown). For example, such as Figure 10 As shown, the third camera 53 can be disposed on the surface of the first circuit board 41 facing away from the first middle frame 1012. The third camera 53 can be... Figure 11 The third lens hole 203 shown receives external light, and the third camera 53 can be used as a front-facing camera.

[0101] Furthermore, when the display terminal 100 is in a flattened state, Figure 13 (for the following) Figure 11 As shown in the schematic diagram (A4 in the diagram), the first display screen 10 and the second display screen 11 can be located on opposite sides of the first housing 101. In this case, different users can be located on opposite sides of the first housing 101 to view the images displayed on the first display screen 10 and the second display screen 11 respectively, thereby increasing the applicable scenarios of the display terminal 100.

[0102] When the display terminal 100 is folded, a portion of the first display screen 10 can be bent. The first display screen 10 is illustrated below with an example. (Continuing with the example...) Figure 12As shown, the first display screen 10 may include a first display unit 1001, a second display unit 1002, a third display unit 1003, a first bending portion 1101, and a second bending portion 1102. The first bending portion 1101 may be connected between the first display unit 1001 and the second display unit 1002, and the second bending portion 1102 may be connected between the second display unit 1002 and the third display unit 1003. In this case, the first display unit 1001, the first bending portion 1101, the second display unit 1002, the second bending portion 1102, and the third display unit 1003 are connected in sequence. Each of the above-mentioned display units and bending portions can be used to display images.

[0103] Continue as Figure 12 As shown, the first display unit 1001 can cover the first housing 101, the first bending portion 1101 can cover the first pivot mechanism 21, the second display unit 1002 can cover the second housing 102, the second bending portion 1102 can cover the second pivot mechanism 22, and the third display unit 1003 can cover the third housing 103. When the display terminal 100 is in a closed state, the first bending portion 1101 and the second bending portion 1102 can undergo flexible deformation and bend, so that during the folding and flattening process of the display terminal 100, the first display screen 10 can also fold and flatten accordingly.

[0104] Based on this, continue as follows Figure 12 As shown, when the display terminal 100 is in the closed state, the first display unit 1001 can be located between the first housing 101 and the third housing 103, and the second display unit 1002 and the third display unit 1003 can be located between the third housing 103 and the second housing 102. Thus, when the display terminal 100 is in the closed state, the first display screen 10 is enclosed within the folding device 20 formed by the first housing 101, the second housing 102, the third housing 103, the first pivot mechanism 21, and the second pivot mechanism 22. This folding device 20 can protect the first display screen 10 from impacts.

[0105] In addition, continue as Figure 12 As shown, when the display terminal 100 is in the closed state, since the first display screen 10 is wrapped inside the folding device 20, there is no positional interference between the first display screen 10, the second display screen 11 disposed on the first housing 101, and the first camera 51 disposed on the second housing 102, thereby improving the integration of the display terminal 100.

[0106] Based on this, such as Figure 14 (for the following) Figure 3As shown in the cross-sectional view obtained by cutting along the dashed lines O3-O4, it can be seen from the above that the average thickness of the first housing 101 can be H1, the average thickness of the second housing 102 can be H2, and the average thickness of the third housing 103 can be H3, with the third housing 103 having the smallest average thickness (e.g., H3). In this case, the average thickness (i.e., H2) of the second housing 102 covered by the second display unit 1002 is different from the average thickness (i.e., H3) of the third housing 103 covered by the third display unit 1003. At this time, the first bend 1101 located between the second display unit 1002 and the third display unit 1003 can be an asymmetrical teardrop-shaped structure (e.g., similar to a golf club shape). One side of the first bend 1101, for example the upper side, can protrude towards the thicker second housing 102. The asymmetric teardrop-shaped structure of the first bending portion 1101 allows the first bending portion 1101 to adapt to the unequal thickness of the second shell 102 and the third shell 103 on both sides of the first bending portion 1101 when it is bent.

[0107] Alternatively, in some other embodiments of this application, when the second housing 102 and the third housing 103 have unequal thicknesses, the first bending portion 1101 can also be a symmetrical teardrop-shaped structure, which is not limited in this application. Furthermore, continuing as... Figure 14 As shown, when the average thickness (i.e., H2) of the second housing 102 covered by the second display portion 1002 is the same as the average thickness (i.e., H1) of the first housing 101 covered by the first display portion 1001, the second bending portion 1102 located between the second display portion 1002 and the first display portion 1001 can be a symmetrical teardrop-shaped structure. Alternatively, when the second housing 102 and the first housing 101 have unequal thicknesses, the second bending portion 1102 can be the aforementioned asymmetrical teardrop-shaped structure.

[0108] The above describes a configuration where the average thickness of the first housing 101 is H1, the average thickness of the second housing 102 is H2, and the average thickness of the third housing 103 is H3, where H3 < H1 and H3 < H2. Furthermore, the camera, for example, the first camera 51... Figure 13 The example shown is an illustration of a second housing 102 positioned in the middle. In other embodiments of this application, such as... Figure 15 As shown, the display terminal 100 may also include a second camera 52. A portion of the second camera 52 is disposed inside the first housing 101, and another portion of the second camera 52 may extend outside the first housing 101.

[0109] like Figure 16 (for the following) Figure 15As shown in the schematic diagram obtained from direction A5 in the figure, a second lens hole 202 can be opened on the first housing 101, and the second lens hole 202 exposes the second camera 52 (as shown in the figure). Figure 15 The light-incident surface (as shown) ensures that external light can pass through the second lens hole 202 and enter the second camera 52. In some embodiments, the display terminal may further include a second DECO 212 covered on the second lens hole 202, the second DECO 212 having a through hole for at least a portion of the light-incident surface of the second camera 52 to pass through.

[0110] For example, such as Figure 17 As shown, the second camera 52 can be stacked on the surface of the first circuit board 41 facing away from the first mid-frame 1012. The second camera 52 can be electrically connected to the first circuit board 41, and the first battery 31 can supply power to the second camera 52 through the circuit traces in the first circuit board 41, so that the second camera 52 can take pictures. This application does not limit the number of second cameras 52.

[0111] The second camera 52 mentioned above can be a rear-facing camera. In some embodiments, such as... Figure 18 As shown, when the display terminal 100 is in the closed state, the second lens hole 202 is located on the side of the first housing 101 away from the third housing 103. In this way, when the display terminal 100 is in the closed state, a portion of the second camera 52 can extend out of the second lens hole 202 in the direction away from the third housing 103, thereby avoiding interference between the positions of the second camera 52 and the third housing 103 when the display terminal 100 is in the closed state.

[0112] In addition, continue as Figure 18 As shown, the display terminal 100 may further include a third display screen 12, which may cover the second housing 102. When the display terminal 100 is in a closed state, the third display screen 12 may be located on the side of the second housing 102 opposite to the third housing 103. In this way, the third display screen 12 can serve as the outer screen of the display terminal 100. When the display terminal 100 is in a closed state, the display surface of the third display screen 12 can be part of the outer surface of the display terminal 100, thereby enabling the display terminal 100 to display images through the third display screen 12 when in a closed state. Furthermore, when the display terminal 100 is in a closed state... Figure 15 In the flattened state shown, the third display screen 12 can be located on the same side as the second camera 52. The third display screen 12 can be an OLED display screen, a micro LED display screen, a QLED display screen, or an LCD.

[0113] The above example illustrates the situation where, when the display terminal 100 is in the closed state, the first display screen 10 is enclosed within a folding device consisting of a first housing 101, a second housing 102, a third housing 103, a first pivot mechanism 21, and a second pivot mechanism 22. In other embodiments of this application, such as... Figure 19 As shown, when the display terminal 100 includes a display screen, such as the first display screen 10 described above, when the display terminal 100 is in a closed state, the first display unit 1001 can be located on the side of the first housing 101 opposite to the third housing 103, the second display unit 1002 can be located on the side of the second housing 102 opposite to the third housing 103, and the third display unit 1003 can be located between the third housing 103 and the first housing 101. In this way, when the display terminal 100 is in a closed state, the first display unit 1001 and the second display unit 1002 can serve as the outer screen of the display terminal 100, thus eliminating the need for a separate outer screen.

[0114] The above example illustrates that the average thickness of the first housing 101 can be H1, the average thickness of the second housing 102 can be H2, and the average thickness of the third housing 103 can be H3, where H3 < H1 and H3 < H2. In other embodiments of this application, such as... Figure 20 As shown, the average thickness of the first shell 101 is H1, the average thickness of the second shell 102 is H3, and the average thickness of the third shell 103 is H2. In this way, the shell with the smallest average thickness, namely the second shell 102, can be located between the first shell 101 and the third shell 103.

[0115] For example, in the case where the display terminal 100 includes a first circuit board 41 and a second circuit board 42, the first circuit board 41 can be located inside the first housing 101, and the second circuit board 42 can be located inside the third housing 103. The housing with the smallest average thickness, i.e., the second housing 102, may not require the installation of a circuit board.

[0116] Based on this, in some embodiments, when the display terminal 100 is in a closed state, such as Figure 21 As shown, the first display unit 1001 and the second display unit 1002 can be used as the outer screen of the display terminal 100 for display. The second display unit 1002 can cover the second housing 102 with the thinnest average thickness (for example, with an average thickness of H3).

[0117] Furthermore, in other embodiments, such as Figure 22As shown, in the case where the display terminal 100 includes a first display screen 10, a second display screen 11, and a first camera 51, similarly, in the first display screen 10, the first display portion 1001 covers the first housing 101, the second display portion 1002 covers the second housing 102, and the third display portion 1003 can cover the third housing 103. Furthermore, the second display screen 11 is located on the side of the first housing 101 facing away from the third housing 103. A portion of the first camera 51 is disposed within the second housing 102 (e.g., with an average thickness of H3), which has the thinnest average thickness. The technical effects of this first camera 51 and the second display screen 11 are the same as described above and will not be repeated here.

[0118] Alternatively, in some other embodiments, such as Figure 23 As shown, in the case where the display terminal 100 includes a first display screen 10, a third display screen 12, and a second camera 52, similarly, in the first display screen 10, the first display unit 1001 covers the first housing 101, the second display unit 1002 covers the second housing 102, and the third display unit 1003 can cover the third housing 103. Furthermore, the third display screen 12 is located on the side of the second housing 102 (e.g., with an average thickness of H3) that is furthest from the third housing 103. A portion of the second camera 52 is disposed within the first housing 101. The technical effects of the second camera 52 and the third display screen 12 are the same as described above and will not be repeated here.

[0119] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes 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.
