Description

Foldable electronic devices, through the use of foldable screens and cleverly designed mechanical structures, successfully combine large screen sizes with portability, providing users with a more flexible user experience.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0039] The directional nouns involved in the embodiments of this application, such as "upper", "lower", "side", etc., are generally expressed in the form of Figure 1 The relative relationships shown in the figure are used as a reference, and these directional terms are used only to more clearly describe the relationship between structures, not to describe absolute directions. When the product is placed in different postures, the direction may change, for example, "up" and "down" may be interchangeable.

[0040] Unless otherwise defined, all technical terms used in the examples of this application have the same meanings as those commonly understood by those skilled in the art. Some technical terms that appear in the examples of this application are explained below.

[0041] In order to make the technical solutions and advantages of the present application clearer, the implementation methods of the present application will be described in further detail below with reference to the accompanying drawings.

[0042] like Figure 3 As shown, an embodiment of the present application provides a foldable electronic device, including a first carrier 1, a second carrier 2, a hinge assembly 3, a first mainboard 4, a second mainboard 5, a hinge flexible circuit board 6 and a connecting structure 7.

[0043] The foldable electronic device includes a first body and a second body. The first carrier 1 and the first main board 4 are both located within the first body, and the second carrier 2 and the second main board 5 are both located within the second body. The first and second bodies are switched between an unfolded state and a folded state via a hinge assembly 3. When the foldable electronic device is in the unfolded state, it has a larger display area, which can enhance the user's visual experience. When the foldable electronic device is in the folded state, it has a smaller planar size, making it easier for the user to carry.

[0044] like Figure 3 As shown, the hinge assembly 3 is disposed between the first carrier 1 and the second carrier 2. The first carrier 1 and the second carrier 2 can be relatively unfolded or folded via the hinge assembly 3, thereby switching the foldable electronic device between the folded and unfolded states. The first carrier 1 and the second carrier 2 are used to carry components, for example, the first carrier 1 and the second carrier 2 are both middle frames.

[0045] The first main board 4 is fixed on the first carrier 1, and the second main board 5 is fixed on the second carrier 2. The first main board 4 and the second main board 5 are used to carry and connect electronic devices.

[0046] The rotating shaft flexible circuit board 6 passes around the rotating shaft assembly 3 , and one end of the flexible circuit board is electrically connected to the first main board 4 , and the other end of the flexible circuit board is electrically connected to the second main board 5 .

[0047] The connection structure 7 is electrically connected to the first carrier 1 and the second carrier 2 respectively, so that electrical signals can be transmitted between the first carrier 1 and the second carrier 2 .

[0048] like Figure 3As shown, the over-the-shaft flexible circuit board 6 spans the hinge assembly 3. The over-the-shaft flexible circuit board 6 is connected to the first main board 4 and the second main board 5 on the upper side of the hinge assembly 3, and the over-the-shaft flexible circuit board 6 passes around the lower side of the hinge assembly 3. Specifically, one end of the over-the-shaft flexible circuit board 6 in the longitudinal direction is electrically connected to and fixed to the first main board 4, and the other end of the over-the-shaft flexible circuit board 6 in the longitudinal direction is electrically connected to and fixed to the second main board 5.

[0049] In related technologies, such as Figure 1 and Figure 2 As shown, the over-axis flexible circuit board 6 is electrically connected to the first main board 4 and the second main board 5 respectively. The over-axis flexible circuit board 6 carries the signal return between the first body and the second body. The reference ground of the first carrier 1 and the second carrier 2 is not fully utilized. A large number of return signals are gathered on the ground layer of the over-axis flexible circuit board 6. The over-axis flexible circuit board 6 requires a large area of ​​grounding copper to carry a large number of return signals. Not only is it easy to cause interference between the signals, resulting in a decrease in signal quality, but it will also cause the local temperature of the over-axis flexible circuit board 6 to rise rapidly, affecting the service life of the over-axis flexible circuit board 6.

[0050] In the embodiments of this application, Figure 3 and Figure 4 As shown, the connection structure 7 is electrically connected to the first carrier 1 and the second carrier 2 respectively, and a new signal return path connecting the first carrier 1 and the second carrier 2 is added in the foldable electronic device, connecting the reference grounds of the first carrier 1 and the second carrier 2, and making full use of the grounds of the first carrier 1 and the second carrier 2, so that a part of the signal can be returned between the first carrier 1 and the second carrier 2 through the newly added signal return path, which improves the defect of the foldable electronic device in the prior art that it has only a single signal return path, helps to improve the signal integrity of the foldable electronic device, realizes the miniaturization of the over-the-hinge flexible circuit board 6, and increases the service life of the over-the-hinge flexible circuit board 6.

[0051] Exemplarily, part of the power supply signal and low-frequency, low-speed signals are returned through the reference ground of the first carrier 1 and the second carrier 2 , and high-frequency, high-speed signals are returned through the flexible printed circuit board 6 over the rotating shaft.

[0052] The foldable electronic device provided in the embodiment of the present application is electrically connected to the first carrier 1 and the second carrier 2 by setting a connecting structure 7, so that electrical signals can be transmitted between the first carrier 1 and the second carrier 2, and a new signal return path is created in the foldable electronic device, so that part of the signal can return through the first carrier 1 and the second carrier 2, reducing signal interference and helping to improve signal integrity; at the same time, it reduces the burden on the over-shaft flexible circuit board 6, which not only avoids a large amount of return signals from converging in the over-shaft flexible circuit board 6, but also helps to reduce the heat accumulation of the over-shaft flexible circuit board 6 during operation, improves the service life of the over-shaft flexible circuit board 6, and also helps to reduce the area of ​​the over-shaft flexible circuit board 6, thereby realizing a miniaturized design of the over-shaft flexible circuit board 6.

[0053] In a further embodiment, the connecting structure 7 is arranged on the flexible circuit board 6 over the rotating shaft, and the connecting structure 7 includes a first connecting part 71 and a second connecting part 72 for electrical connection. The first connecting part 71 is used to electrically connect to the first carrier 1, and the second connecting part 72 is used to electrically connect to the second carrier 2.

[0054] In this embodiment, by providing the first connecting portion 71 and the second connecting portion 72, electrical connection and signal transmission between the first carrier 1 and the second carrier 2 are achieved, the reference ground of the first carrier 1 and the second carrier 2 are effectively utilized, and the first carrier 1 and the second carrier 2 are used to share a part of the bearing pressure of the over-rotating shaft flexible circuit board 6 for the return signal; by providing the connecting structure 7 on the over-rotating shaft flexible circuit board 6, it is beneficial to reduce the space occupied by the connecting structure 7, so that the space allocation inside the foldable electronic device is more reasonable and compact.

[0055] Furthermore, the over-axis flexible circuit board 6 includes a first conductive layer 61 and a second conductive layer 62 connected in a stacked manner. The first conductive layer 61 is electrically connected to the first main board 4 and the second main board 5 respectively. The first connecting portion 71 and the second connecting portion 72 are both arranged in the second conductive layer 62.

[0056] like Figure 5 As shown, the first conductive layer 61 is located above the second conductive layer 62 , the first conductive layer 61 is the top layer, and the second conductive layer 62 is the bottom layer.

[0057] By disposing the first connecting portion 71 and the second connecting portion 72 within the second conductive layer 62, a layered signal return design for the over-the-hinge flexible circuit board 6 is achieved. The first conductive layer 61 electrically connects the over-the-hinge flexible circuit board 6 to the first and second main boards 4 and 5, allowing signals to return between the first and second main boards 4 and 5. The second conductive layer 62 electrically connects the over-the-hinge flexible circuit board 6 to the first and second support members 1 and 2, allowing signals to return between the first and second support members 1 and 2. This adds a new signal return path to the foldable electronic device, reducing the pressure on the over-the-hinge flexible circuit board 6 to handle the return signal.

[0058] The first connecting portion 71 and the second connecting portion 72 are both arranged in the second conductive layer 62. Not only is the electrical connection and signal transmission between the first connecting portion 71 and the second connecting portion 72 achieved through the second conductive layer 62, but the conventional structure of the flexible circuit board 6 itself over the rotating shaft is also utilized to reduce the space occupied by the first connecting portion 71 and the second connecting portion 72, making the space allocation inside the foldable electronic device more reasonable and compact.

[0059] In a further embodiment, both ends of the second conductive layer 62 in the length direction are separated from both ends of the first conductive layer 61 in the length direction, thereby forming a first connecting portion 71 and a second connecting portion 72 at both ends of the second conductive layer 62 in the length direction.

[0060] like Figure 5 and Figure 6 As shown, the two ends of the first conductive layer 61 are not connected to the two ends of the second conductive layer 62, one end of the second conductive layer 62 in the length direction forms a first connecting portion 71, and the other end of the second conductive layer 62 in the length direction forms a second connecting portion 72.

[0061] In this embodiment, the two ends of the second conductive layer 62 in the length direction are respectively used as the first connecting part 71 and the second connecting part 72, which can avoid the phenomenon of poor electrical connection between the first connecting part 71 and the second connecting part 72, thereby improving the electrical connection reliability between the first carrier 1 and the second carrier 2; at the same time, the conventional structure of the over-the-axis flexible circuit board 6 itself is fully utilized, and the additional processing steps of connecting other conductive elements on the over-the-axis flexible circuit board 6 are eliminated, which not only realizes the layered signal return design of the over-the-axis flexible circuit board 6, but also helps to reduce the processing time and improve the production efficiency of foldable electronic devices.

[0062] In a specific embodiment, Figure 5 and Figure 6 As shown, both ends of the first conductive layer 61 in the length direction, the first connecting portion 71 and the second connecting portion 72 are connected to the board-to-board connector 8 .

[0063] The board-to-board connector 8 is also called a BTB (Board-to-Board) connector, which can provide a reliable electrical connection and realize signal transmission.

[0064] Specifically, the board-to-board connector 8 at one end of the first conductive layer 61 is snapped onto the first main board 4, and the board-to-board connector 8 at the other end of the first conductive layer 61 is snapped onto the second main board 5; the board-to-board connector 8 on the first connecting portion 71 is snapped onto the first carrier 1, and the board-to-board connector 8 on the second connecting portion 72 is snapped onto the second carrier 2.

[0065] In one embodiment, the first carrier 1 and the second carrier 2 are both provided with third connection portions 11 , the first connection portion 71 is electrically connected to one of the third connection portions 11 , and the second connection portion 72 is electrically connected to the other third connection portion 11 .

[0066] By arranging the third connection portion 11 on the first carrier 1 and the second carrier 2 , electrical connection and signal transmission between the first carrier 1 and the second carrier 2 are achieved by utilizing the first connection portion 71 , the second connection portion 72 and the third connection portion 11 .

[0067] Furthermore, the third connection part 11 is a conductive protrusion, the first connection part 71 and the second connection part 72 are conductive vias opened on the rotating shaft flexible circuit board 6, and the third connection part 11 is inserted into the first connection part 71 or the second connection part 72; or, the first connection part 71 and the second connection part 72 are conductive protrusions, the third connection part 11 is a conductive hole, and the first connection part 71 and the second connection part 72 are respectively inserted into a third connection part 11.

[0068] Alternatively, as Figure 7 As shown, the third connecting portion 11 is a conductive protrusion. It protrudes from the sidewall of the first carrier 1 and is inserted into the first connecting portion 71. A via is a hole in a flexible printed circuit board (FPC) used to connect conductors between layers of the FPC, achieving electrical connection and securing components. For example, the edges of the vias in the rotating shaft FPC 6 are copper-plated to create conductive vias.

[0069] In this embodiment, by configuring the first and second connecting portions 71 and 72 as conductive vias on the hinge-through flexible circuit board 6, the conventional structure of the hinge-through flexible circuit board 6 is utilized to achieve electrical connection and signal transmission between the third connecting portion 11 and the first and second connecting portions 71 and 72, thereby reducing processing time and improving the production efficiency of foldable electronic devices. It is understood that the connection method between the third connecting portion 11 and the second connecting portion 72 is similar to the connection method between the third connecting portion 11 and the first connecting portion 71, and will not be further described here.

[0070] Optionally, a raised conductive stud is provided on the flexible circuit board 6 over the rotating shaft, and the conductive stud serves as the first connecting portion 71 and the second connecting portion 72. A conductive hole with conductive capability is provided on the first carrier 1 and the second carrier 2, and the conductive hole serves as the third connecting portion 11. By inserting the conductive stud into the conductive hole, electrical connection and signal transmission between the first carrier 1 and the second carrier 2 are achieved. The conductive hole can be a through hole or a blind hole, which is not specifically limited in this embodiment of the application.

[0071] In one embodiment, the first connection portion 71 and the second connection portion 72 are both conductive reinforcing plates, and the first connection portion 71 and the second connection portion 72 extend along the width direction of the flexible circuit board 6 passing through the shaft.

[0072] Specifically, the first connecting portion 71 and the second connecting portion 72 are spaced apart along the length direction of the flexible printed circuit board 6 .

[0073] In this embodiment, the first connecting portion 71 and the second connecting portion 72 are both conductive reinforcement plates arranged on the over-axis flexible circuit board 6, which can not only improve the structural strength of the over-axis flexible circuit board 6, but also realize electrical connection and signal transmission between the first carrier 1 and the second carrier 2.

[0074] Furthermore, both ends of the first connecting portion 71 are electrically connected to the first carrier 1 and fixed to the first surface 12 of the first carrier 1; both ends of the second connecting portion 72 are electrically connected to the second carrier 2 and fixed to the second surface of the second carrier 2; and the over-rotating flexible circuit board 6 is spaced apart from the first surface 12 and the second surface, respectively. When the first carrier 1 and the second carrier 2 are relatively unfolded, the first surface 12 and the second surface are opposite each other.

[0075] like Figure 8 As shown, both ends of the first connecting portion 71 in the longitudinal direction are connected to the first surface 12, forming a cover-shaped structure between the over-the-axle flexible circuit board 6 and the first carrier 1. A gap exists between the over-the-axle flexible circuit board 6 and the first surface 12, thereby providing space for the over-the-axle flexible circuit board 6 to move, preventing the over-the-axle flexible circuit board 6 from bending during the relative folding or unfolding of the first carrier 1 and the second carrier 2, and protecting the over-the-axle flexible circuit board 6 from being pulled and damaged. It is understandable that the connection method of the second connecting portion 72 and the second carrier 2 is similar to the connection method of the first connecting portion 71 and the first carrier 1, and will not be repeated here.

[0076] In one embodiment, Figure 9As shown, the shaft assembly 3 includes a shaft body 31 and a hinge 32 mounted on the shaft body 31 , the hinge 32 is connected to the first carrier 1 and the second carrier 2 respectively, and the hinge 32 is electrically connected to the first connecting portion 71 and the second connecting portion 72 respectively.

[0077] The hinge 32 is used to realize the movable connection between the first carrier 1 and the hinge body 31, and the second carrier 2 and the hinge body 31, so that the first body and the second body of the foldable electronic device can be switched between the unfolded state and the folded state through the hinge assembly 3.

[0078] Exemplarily, the hinge 32 is made of a metal material having electrical conductivity, so that it can be electrically connected to the first carrier 1 and the second carrier 2 respectively.

[0079] Optionally, there are one or more hinges 32 , and at least one hinge 32 is electrically connected to the first connecting portion 71 and the second connecting portion 72 , respectively.

[0080] Alternatively, there are multiple hinges 32, some of the hinges 32 are connected to the first carrier 1, and other parts of the hinges 32 are connected to the second carrier 2, the hinge body 31 has conductivity and can be electrically connected to the hinge 32, at least one hinge 32 connected to the first carrier 1 is electrically connected to the first connecting portion 71, and at least one hinge 32 connected to the second carrier 2 is electrically connected to the second connecting portion 72.

[0081] In this embodiment, by setting a hinge 32 to be electrically connected to the first connecting part 71 and the second connecting part 72 respectively, the conventional structure of the hinge assembly 3 itself is utilized to achieve electrical connection and signal transmission between the first carrier 1 and the second carrier 2, which is beneficial to reducing processing time and improving the production efficiency of foldable electronic devices.

[0082] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless expressly limited otherwise.
