Detailed implementation manners

[0065] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0066] In recent years, with the rapid development of technologies such as flexible screens and hinges, the market share of electronic devices such as foldable mobile phones and foldable tablet computers has been increasing day by day. They can meet the user's demand for large-screen display in a smaller space and have been widely used in people's daily lives. In related technologies, a foldable electronic device, as Figure 1 shown, is divided into a mechanism area 1 and an over-axis circuit board area 2 along the extension direction of the rotation axis. The mechanism area 1 is used to arrange parts of the hinge assembly, and the over-axis circuit board area 2 is used to arrange the over-axis flexible circuit board. The over-axis flexible circuit board is used to transmit electrical signals between devices on both sides of the rotation axis of the folding device.

[0067] However, for an electronic device using related technologies, the over-axis flexible circuit board is used to transmit electrical signals on both sides of the rotation axis. The over-axis flexible circuit board rotates as the device folds and unfolds. If parts of the hinge assembly are arranged in the over-axis circuit board area 2, it will affect the bending space of the over-axis flexible circuit board and cause the over-axis flexible circuit board to break. Therefore, it is impossible to arrange parts of the hinge assembly in the over-axis flexible circuit board area, resulting in problems such as insufficient strength of the parts of the hinge assembly and poor folding feel of the device, which affect the product competitiveness.

[0068] Based on this, the exemplary embodiments of the present disclosure provide an electronic device. By forming at least part of the structure of the hinge assembly into an electrical connection structure and using the electrical connection structure for transmitting electrical signals between the first device and the second device, the hinge assembly can be used for folding the electronic device while also being able to transmit electrical signals, reducing the number of electrical signals that the over-axis flexible circuit board needs to transmit, thereby reducing the space occupied by the over-axis flexible circuit board, ensuring the strength of the parts of the hinge assembly and the folding feel of the device, and enhancing the product competitiveness.

[0069] In one exemplary embodiment, an electronic device is provided. The electronic device can be, for example, a foldable mobile phone, a foldable tablet computer, or the like. Referring to Figure 2 shown, the electronic device includes at least two folding parts and a hinge assembly 20. One folding part includes at least one first device, and the other folding part includes at least one second device. Adjacent folding parts are connected by the hinge assembly so that the adjacent folding parts can be folded and unfolded relative to each other through the hinge assembly.

[0070] At least part of the structure of the hinge assembly 20 constitutes an electrical connection structure, which is used for electrical signal transmission between at least one first device and at least one second device.

[0071] The number of folding parts can be, for example, 2, 3, or N, where N is a positive integer greater than 3. Exemplarily, when the number of folding parts is two, the two folding parts can be the first folding part 11 and the second folding part 12 as shown. One of the multiple folding parts includes at least one first device, and another of the multiple folding parts includes at least one second device. Both the first device and the second device are devices that support the operation and use of the electronic device. The hinge assembly 20 is composed of multiple components. The hinge assembly 20 is disposed between adjacent folding parts and is used to connect adjacent folding parts and enable the adjacent folding parts to fold and open relative to each other to achieve the folding function of the electronic device. Figure 2 At least part of the structure of the hinge assembly 20 constitutes an electrical connection structure. The electrical connection structure can be electrically connected to at least one first device and at least one second device respectively, and the electrical connection structure itself can serve as a medium for transmitting electrical signals, enabling at least one first device to transmit electrical signals to at least one second device through the electrical connection structure. Exemplarily, some components of the hinge assembly 20 form the electrical connection structure. The electrical connection structure as a whole is made of a conductive material or a conductive path formed by multiple segments of conductive material is formed in the electrical connection structure. The electrical connection structure can be used for electrical signal transmission between one first device and one second device, one first device and multiple second devices, multiple first devices and one second device, or multiple first devices and multiple second devices.

[0072] Compared with the electronic devices in the related art, at least part of the structure of the hinge assembly 20 of the electronic device in this embodiment constitutes an electrical connection structure, which can transmit one or more electrical signals through the electrical connection structure, sharing the number of electrical signals that need to be transmitted by the through-axis flexible circuit board. Therefore, the size of the through-axis flexible circuit board can be reduced, and more available space can be provided for the setting of the hinge assembly 20.

[0073] In this embodiment, by forming at least part of the structure of the hinge assembly 20 into an electrical connection structure and using the electrical connection structure for electrical signal transmission between the first device and the second device, the hinge assembly 20 can be used for folding the electronic device while also realizing electrical signal transmission, reducing the number of electrical signals that the through-axis flexible circuit board needs to transmit, thereby reducing the space occupied by the through-axis flexible circuit board, ensuring the part strength of the hinge assembly 20 and the folding feel of the device, and enhancing the product competitiveness.

[0075] In some embodiments, refer to Figure 2As shown, at least two folding parts include a first folding part 11 and a second folding part 12. The first folding part 11 includes at least one first device, and the second folding part 12 includes at least one second device. The hinge assembly 20 is used to connect the first folding part 11 and the second folding part 12 and enable the first folding part 11 and the second folding part 12 to fold and open relative to each other.

[0076] The folding parts of the electronic device include a first folding part 11 and a second folding part 12. The first folding part 11 and the second folding part 12 are arranged opposite to each other. The first folding part 11 includes at least one first device, and the second folding part 12 includes at least one second device. Both the first device and the second device are devices that support the operation and use of the electronic device. The hinge assembly 20 is arranged between the first folding part 11 and the second folding part 12. The hinge assembly 20 is used to connect the first folding part 11 and the second folding part 12 on both sides and enable the first folding part 11 and the second folding part 12 to fold and open relative to each other to achieve the folding function of the electronic device.

[0077] In this embodiment, the electrical connection structure of the hinge assembly 20 can be used for the electrical signal transmission between the first device on the first folding part 11 and the second device on the second folding part 12, so that the hinge assembly 20 can realize the electrical signal transmission while the electronic device is folded, reducing the number of electrical signals that need to be transmitted by the through-axis flexible circuit board, thereby reducing the space occupied by the through-axis flexible circuit board, ensuring the part strength of the hinge assembly 20 and the folding feel of the device, and enhancing the product competitiveness. In some embodiments, refer to Figure 3 As shown, the hinge assembly 20 includes a fixed assembly 33 and a first rotating assembly 31 and a second rotating assembly 32 respectively connected to both sides of the fixed assembly 33. One end of the first rotating assembly 31 is rotatably connected to the fixed assembly 33, and the other end of the first rotating assembly 31 is fixedly connected to the first folding part 11.

[0078] The hinge assembly 20 includes a fixed assembly 33, and a first rotating assembly 31 and a second rotating assembly 32 respectively connected to both sides of the fixed assembly 33. The first rotating assembly 31 and the second rotating assembly 32 can be symmetrically arranged relative to the fixed assembly 33 and composed of the same components. One end of the first rotating assembly 31 is rotatably connected to the fixed assembly 33, and the other end of the first rotating assembly 31 is fixedly connected to the first folding portion 11, so that the first rotating assembly 31 can drive the first folding portion 11 to rotate relative to the fixed assembly 33, so that the first folding portion 11 can move closer to and away from the second folding portion 12. One end of the second rotating assembly 32 is rotatably connected to the fixed assembly 33, and the other end of the second rotating assembly 32 is fixedly connected to the second folding portion 12, so that the second rotating assembly 32 can drive the second folding portion 12 to rotate relative to the fixed assembly 33, so that the second folding portion 12 can move closer to and away from the first folding portion 11, and further enabling the hinge assembly 20 to be used for the relative folding and opening of the first folding portion 11 and the second folding portion 12.

[0079] The first rotating assembly 31 is electrically connected to at least one first device on the first folding portion 11 and the fixed assembly 33, forming an electrical connection path of the first device - the first rotating assembly 31 - the fixed assembly 33. The second rotating assembly 32 is electrically connected to at least one second device on the second folding portion 12 and the fixed assembly 33, forming an electrical connection path of the second device - the second rotating assembly 32 - the fixed assembly 33. Both electrical connection paths use the fixed assembly 33 as the end point of the electrical connection path, jointly forming an electrical connection path of the first device - the first rotating assembly 31 - the fixed assembly 33 - the second rotating assembly 32 - the second device, enabling the first device and the second device to transmit signals through the first rotating assembly 31, the fixed assembly 33, and the second rotating assembly 32.

[0080] In this embodiment, by rotatably connecting one end of the first rotating assembly 31 and the second rotating assembly 32 to the fixed assembly 33, and fixedly connecting the other ends of the first rotating assembly 31 and the second rotating assembly 32 to the first folding portion 11 and the second folding portion 12 respectively, the first folding portion 11 and the second folding portion 12 can move closer to and away from each other, and the folding function of the electronic device is realized through the hinge assembly 20. By electrically connecting the first rotating assembly 31 to at least one first device and the fixed assembly 33, and electrically connecting the second rotating assembly 32 to at least one second device and the fixed assembly 33, an electrical connection path of the first device - the first rotating assembly 31 - the fixed assembly 33 - the second rotating assembly 32 - the second device is formed, and the signal transmission function is realized through the electrical connection structure of the hinge assembly 20.

[0081] In some embodiments, at least a portion of the first rotating component 31 is made of a conductive material to transmit an electrical signal through the first rotating component 31. Alternatively, the first rotating component 31 includes a first conductive connection structure to transmit an electrical signal through the first conductive connection structure.

[0082] The first rotating component 31, the second rotating component 32, and the fixed component 33 themselves also need to be able to transmit electrical signals. At least a portion of each of the first rotating component 31, the second rotating component 32, and the fixed component 33 can be set as a conductive material, and the portions of the first rotating component 31, the second rotating component 32, and the fixed component 33 that are made of the conductive material are used as part of the electrical connection structure to transmit electrical signals through the first rotating component 31, the second rotating component 32, and the fixed component 33 themselves. It is also possible to respectively provide a first conductive connection structure, a second conductive connection structure, and a third conductive connection structure in the first rotating component 31, the second rotating component 32, and the fixed component 33, and use the first conductive connection structure, the second conductive connection structure, and the third conductive connection structure as part of the electrical connection structure to transmit electrical signals through the first conductive connection structure, the second conductive connection structure, and the third conductive connection structure.

[0083] The conductive connection structure is also made of a conductive material. The conductive material can be, for example, a metal material such as copper. When at least a portion of the first rotating component 31, the second rotating component 32, and the fixed component 33 is made of a conductive material, or when the first conductive connection structure, the second conductive connection structure, and the third conductive connection structure are made of a conductive material, electrical signals can be transmitted. For the first rotating component 31, the second rotating component 32, and the fixed component 33 themselves, there are two different ways to transmit electrical signals, and the electrical signal transmission of the first rotating component 31, the second rotating component 32, and the fixed component 33 can be achieved through any combination.

[0084] In this embodiment, by setting at least a part of the first rotating component 31, the second rotating component 32, and the fixing component 33 as conductive materials, or by respectively providing a first conductive connection structure, a second conductive connection structure, and a third conductive connection structure in the first rotating component 31, the second rotating component 32, and the fixing component 33, the transmission of electrical signals can be achieved through the conductive parts or the conductive connection structures therein in the first rotating component 31, the second rotating component 32, and the fixing component 33, so that the electrical signals can be transmitted inside the first rotating component 31, the second rotating component 32, and the fixing component 33, providing a basis for the transmission of electrical signals between the first device and the second device.

[0085] In some embodiments, at least one of the first rotating component 31 and the second rotating component 32 includes a first rotating part, the fixing component 33 includes a first rotating mating part that mates with the first rotating part, and the first rotating part can rotate relative to the first rotating mating part; the first rotating part is electrically connected to the first rotating mating part.

[0086] Either or both of the first rotating component 31 and the second rotating component 32 are provided with a first rotating part, the fixing component 33 includes a first rotating mating part that can mate with the first rotating part, and the first rotating part on the first rotating component 31 or the second rotating component 32 can rotate relative to the first rotating mating part of the fixing component 33 to realize the rotational connection between the first rotating component 31 and the second rotating component 32 and the fixing component 33, and the first rotating part is electrically connected to the first rotating mating part to realize the electrical connection between the first rotating component 31 and the second rotating component 32 and the fixing component 33.

[0087] In this embodiment, by providing a first rotating part in the first rotating component 31 and the second rotating component 32 and providing a first rotating mating part in the fixing component 33, the rotational connection between the first rotating component 31 and the second rotating component 32 and the fixing component 33 is realized. By setting the first rotating part and the first rotating mating part to be electrically connected, the electrical connection between the first rotating component 31 and the second rotating component 32 and the fixing component 33 is realized, so that the electrical signals can be transmitted inside the first rotating component 31, the second rotating component 32, and the fixing component 33, providing a basis for the transmission of electrical signals between the first device and the second device.

[0088] In some embodiments, referring to Figure 3 As shown, the fixing component 33 includes a first bracket 41 and a second bracket 42, and the gap between the first bracket 41 and the second bracket 42 forms a first rotating groove 43. The first rotating mating part includes the first rotating groove 43. At least one of the first rotating component 31 and the second rotating component 32 includes a first rotating member 51, and the first rotating member 51 can rotate along the corresponding first rotating groove 43 and is electrically connected to the groove wall of the first rotating groove 43.

[0089] The fixing component 33 includes a first bracket 41 and a second bracket 42. The first bracket 41 and the second bracket 42 can be relatively fixed, for example, by a fixing connection structure connecting the two. There is a gap between the first bracket 41 and the second bracket 42, and this gap forms a first rotation groove 43. The cross-sectional shape of the first rotation groove 43 can be, for example, an arc shape.

[0090] At least one of the first rotation component 31 and the second rotation component 32 includes a first rotating member 51. The cross-sectional shape of the first rotating member 51 is adapted to the first rotation groove 43. The first rotating members 51 of the first rotation component 31 and the second rotation component 32 can both rotate along the first rotation groove 43 and are electrically connected to the groove wall of the first rotation groove 43, so that the first rotation component 31 and the second rotation component 32 are rotationally connected and electrically connected to the fixing component 33. When the first rotating members 51 of the first rotation component 31 and the second rotation component 32 rotate along the first rotation groove 43, the electronic device can be switched between the open state as shown in Figure 3 and the folded state as shown in Figure 4 .

[0091] It should be noted that the groove walls electrically connected to the first rotating member 51 of the first rotation component 31 and the first rotating member 51 of the second rotation component 32 are both the surface of the first bracket 41 or both the surface of the second bracket 42. When the groove walls electrically connected to the first rotating member 51 of the first rotation component 31 and the first rotating member 51 of the second rotation component 32 are the surface of the first bracket 41, an electrical connection path of the first rotating member 51 of the first rotation component 31 - the first bracket 41 - the first rotating member 51 of the second rotation component 32 is formed. When the groove walls electrically connected to the first rotating member 51 of the first rotation component 31 and the first rotating member 51 of the second rotation component 32 are the surface of the second bracket 42, an electrical connection path of the first rotating member 51 of the first rotation component 31 - the second bracket 42 - the first rotating member 51 of the second rotation component 32 is formed. In both cases, an electrical connection path of the first rotation component 31 - the fixing component 33 - the second rotation component 32 is formed, so that both the first rotation component 31 and the second rotation component 32 are electrically connected to the fixing component 33.

[0092] In this embodiment, a first rotation groove 43 is formed by the gap between the first bracket 41 and the second bracket 42 of the fixing component 33 and serves as a first rotation mating portion, enabling the first rotating members 51 of the first rotating component 31 and the second rotating component 32 to rotate along the first rotation groove 43 and be electrically connected to the groove wall of the first rotation groove 43. This realizes the rotational connection between the first rotating component 31 and the second rotating component 32 and the fixing component 33, and also realizes the electrical connection between the first rotating component 31 and the second rotating component 32 and the fixing component 33, allowing electrical signals to be transmitted through the electrical connection path of the first rotating component 31 - fixing component 33 - second rotating component 32, providing a basis for the transmission of electrical signals between the first device and the second device.

[0093] In some embodiments, referring to Figure 5 and Figure 6 as shown, the first rotating member 51 includes a mating portion 53 and a non - mating portion 54. When the first folding portion 11 and the second folding portion 12 are in the unfolded state as shown in Figure 3 the mating portion 53 contacts the first bracket 41, and there is a gap between the non - mating portion 54 and the first bracket 41. An elastic conductive structure 52 is provided on the non - mating portion 54 and / or the first bracket 41. The elastic conductive structure 52 provided on one of the non - mating portion 54 and the first bracket 41 abuts against the other of the non - mating portion 54 and the first bracket 41, and the first rotating member 51 is electrically connected to the first bracket 41 through the elastic conductive structure 52.

[0094] The first rotating member 51 includes a mating portion 53 and a non - mating portion 54. When the first folding portion 11 and the second folding portion 12 are in the unfolded state, the mating portion 53 of the first rotating member 51 of the first rotating component 31 contacts the first bracket 41, and there is a gap and separation between the non - mating portion 54 and the first bracket 41. The mating portion 53 of the first rotating member 51 of the second rotating component 32 contacts the first bracket 41, and there is a gap and separation between the non - mating portion 54 and the first bracket 41.

[0095] Since the mating portion 53 contacts the first bracket 41, the mating portion 53 undergoes relatively large wear during the rotation of the rotating member. If the first rotating member 51 is electrically connected to the first bracket 41 through the mating portion 53, the stability of the electrical connection between the first rotating member 51 and the first bracket 41 will be insufficient. An elastic conductive structure 52 can be provided on the non - mating portion 54, or on the first bracket 41, or on both the non - mating portion 54 and the first bracket 41, and it is ensured that the elastic conductive structure 52 provided on the first bracket 41 abuts against the non - mating portion 54, and the elastic conductive structure 52 provided on the non - mating portion 54 abuts against the first bracket 41, and the electrical connection between the first rotating member 51 and the first bracket 41 is realized through the elastic conductive structure 52.

[0096] It can be understood that when the elastic conductive structure 52 is disposed on the first bracket 41, the elastic conductive structure 52 is disposed on the first bracket 41 in a region corresponding to the non-mating portion 54. The elastic conductive structure 52 can be, for example, an elastic metal material, such that the elastic conductive structure 52 can serve as a medium for transmitting electrical signals and the elastic conductive structure 52 always maintains contact with the first rotating member 51 or the first bracket 41 during the rotation of the first rotating member 51.

[0097] In this embodiment, by disposing the elastic conductive structure 52 on the non-mating portion 54 having a gap with the first bracket 41, or by disposing the elastic conductive structure 52 at a position corresponding to the non-mating portion 54 on the first bracket 41, the electrical connection between the non-mating portion 54 and the first bracket 41 can be achieved through the elastic conductive structure 52. Furthermore, the electrical connection with the first bracket 41 can be realized at a position where the first rotating member 51 is less worn, avoiding the regions of long-term extrusion and wear, and preventing serious wear or damage to the elastic conductive structure 52. Additionally, due to the elastic characteristics of the elastic conductive structure 52, it always maintains contact with the first rotating member 51 or the first bracket 41, ensuring the stability of the electrical signal transmission between the first rotating member 51 and the first bracket 41.

[0098] In some embodiments, the elastic conductive structure 52 is selected from at least one of a spring piece, an arc-shaped elastic strip, and a first elastic connecting member. One end of the spring piece is fixed to one of the non-mating portion 54 and the first bracket 41, and the other end of the spring piece abuts against the other of the non-mating portion 54 and the first bracket 41. The arc-shaped elastic strip is fixed to one of the non-mating portion 54 and the first bracket 41, and the outer side surface of the arc-shaped elastic strip abuts against the other of the non-mating portion 54 and the first bracket 41. The first elastic connecting member is fixed to one of the non-mating portion 54 and the first bracket 41, and the end of the first elastic connecting member abuts against the other of the non-mating portion 54 and the first bracket 41.

[0099] The elastic conductive structure 52 can be a spring piece, an arc-shaped elastic strip, or a first elastic connecting member. The spring piece is a sheet-like structure, the arc-shaped elastic strip is an arc-shaped bar structure, and the first elastic connecting member can be, for example, a setscrew structure. Exemplarily, as shown in Figure 5 and Figure 6 , the arc-shaped elastic strip can be fixed to the non-mating portion 54 by integral molding or welding. During the rotation of the first rotating member 51, the outer side surface of the arc-shaped elastic strip always abuts against the first bracket 41, enabling the first rotating member 51 to be electrically connected to the first bracket 41 through the arc-shaped elastic strip.

[0100] In this embodiment, the elastic conductive structure 52 is a shrapnel, an arc-shaped elastic strip or a first elastic connecting member, which is respectively fixed to and abutted against the non-mating portion 54 and the first bracket 41. The electrical connection between the first rotating member 51 and the first bracket 41 can be realized through the elastic conductive structure 52 in a variety of different ways, avoiding serious wear or damage to the elastic conductive structure 52 and ensuring the stability of the electrical signal transmission between the first rotating member 51 and the first bracket 41.

[0101] In some embodiments, the first rotating member 51 is made of a conductive material, and the surface of the first rotating member 51 is covered with a first wear-resistant layer; the first bracket 41 is made of a conductive material, and the surface of the first bracket 41 is covered with a second wear-resistant layer. One of the first wear-resistant layer and the second wear-resistant layer is provided with a first hollowed-out area, and the internal conductive material is exposed through the first hollowed-out area to fix the elastic conductive structure 52. The other of the first wear-resistant layer and the second wear-resistant layer is provided with a second hollowed-out area extending along the movement path of the elastic conductive structure 52, and the internal conductive material is exposed through the second hollowed-out area to abut against the elastic conductive structure 52.

[0102] Most of the components of the hinge assembly 20 are made of metal. However, due to the requirements of surface rust prevention and wear resistance, surface treatments such as wear-resistant layers are usually required for each component, and the wear-resistant layer will block the transmission of electrical signals between the components. To solve this problem, on the basis that the surface of the first rotating member 51 is covered with a first wear-resistant layer and the surface of the first bracket 41 is covered with a second wear-resistant layer, a first hollowed-out area is provided in the first wear-resistant layer or the second wear-resistant layer. The conductive material of the first rotating member 51 or the first bracket 41 is exposed through the first hollowed-out area to fix the elastic conductive structure 52, so that the elastic conductive structure 52 is electrically connected to the first rotating member 51 or the first bracket 41. Then, a second hollowed-out area extending along the movement path of the elastic conductive structure 52 is provided in the second wear-resistant layer or the first wear-resistant layer. The conductive material of the first bracket 41 or the first rotating member 51 is exposed through the second hollowed-out area to abut against the elastic conductive structure 52, so that the elastic conductive structure 52 is electrically connected to the first bracket 41 or the first rotating member 51, thereby ensuring that the first rotating member 51 can be electrically connected to the first bracket 41 through the elastic conductive structure 52.

[0103] In this embodiment, by providing a first hollowed-out area in one of the first wear-resistant layer and the second wear-resistant layer, and providing a second hollowed-out area extending along the movement path of the elastic conductive structure 52 in the other of the first wear-resistant layer and the second wear-resistant layer, the conductive materials inside the first rotating member 51 and the first bracket 41 can be exposed through the first hollowed-out area and the second hollowed-out area respectively to fix and abut against the elastic conductive structure 52, ensuring the electrical connection between the first rotating member 51 and the first bracket 41 on the premise of meeting the requirements of rust prevention and wear resistance in other areas.

[0104] In some embodiments, referring to Figure 3 andFigure 7 As shown, at least one of the first rotating component 31 and the second rotating component 32 includes a fixing member 61, and both the first folding portion 11 and the second folding portion 12 include a middle frame 62. The fixing member 61 of the first rotating component 31 is fixedly connected to the middle frame 62 of the first folding portion 11 to be electrically connected to at least one first device on the first folding portion 11 through the middle frame 62 of the first folding portion 11. The fixing member 61 of the second rotating component 32 is fixedly connected to the middle frame 62 of the second folding portion 12 to be electrically connected to at least one second device on the second folding portion 12 through the middle frame 62 of the second folding portion 12.

When the first rotating component 31 includes the fixing member 61, the fixing member 61 of the first rotating component 31 is fixedly connected to the middle frame 62 of the first folding portion 11. When the first rotating component 31 rotates relative to the fixed component 33, it can drive the middle frame 62 of the first folding portion 11 and the first device provided on the middle frame 62 to rotate, and can be electrically connected to the first device provided on the middle frame 62 through the middle frame 62 of the first folding portion 11, realizing the fixed connection between the first rotating component 31 and the first folding portion 11, and realizing the electrical connection between the first rotating component 31 and at least one first device through the electrical connection path of the first device - middle frame 62 - fixing member 61. When the second rotating component 32 includes the fixing member 61, the fixing member 61 of the second rotating component 32 is fixedly connected to the middle frame 62 of the second folding portion 12. When the second rotating component 32 rotates relative to the fixed component 33, it can drive the middle frame 62 of the second folding portion 12 and the second device provided on the middle frame 62 to rotate, and can be electrically connected to the second device provided on the middle frame 62 through the middle frame 62 of the second folding portion 12, realizing the fixed connection between the second rotating component 32 and the second folding portion 12, and realizing the electrical connection between the second rotating component 32 and at least one second device through the electrical connection path of the second device - middle frame 62 - fixing member 61.

[0106] In this embodiment, by providing the fixing member 61 in the first rotating component 31 and the second rotating component 32, and making the fixing member 61 of the first rotating component 31 and the fixing member 61 of the second rotating component 32 be fixedly connected to the middle frames 62 of the first folding portion 11 and the second folding portion 12 respectively, it can be electrically connected to at least one first device and at least one second device respectively through the middle frames 62 of the first folding portion 11 and the second folding portion 12, realizing the fixed connection between the first rotating component 31 and the first folding portion 11 and the electrical connection with at least one first device, and realizing the fixed connection between the second rotating component 32 and the second folding portion 12 and the electrical connection with at least one second device, providing a basis for the transmission of electrical signals between the first device and the second device.

[0108] When the fixing member 61 is fixedly connected to and in contact with the middle frame 62, the fixing member 61 and the corresponding middle frame 62 can be electrically connected by direct contact. When the fixing member 61 is fixedly connected to the corresponding middle frame 62 by a fastener 63, the fixing member 61 and the corresponding middle frame 62 can also use the fastener 63 as a medium for transmitting electrical signals to achieve the electrical connection between the fixing member 61 and the corresponding middle frame 62. The fastener 63 can be, for example, a screw or a bolt and other structures.

[0109] In this embodiment, the fixing member 61 and the corresponding middle frame 62 can be electrically connected either by direct contact or by means of the fastener 63, which provides a basis for the fixing member 61 to be electrically connected to at least one first device on the first folding portion 11 or at least one second device on the second folding portion 12 through the middle frame 62, realizing the electrical connection between the first rotating assembly 31 and at least one first device and the second rotating assembly 32 and at least one second device, and then forming an electrical connection path of the first device - middle frame 62 - first rotating assembly 31 - fixing assembly 33 - second rotating assembly 32 - middle frame 62 - second device, and realizing the signal transmission function through the electrical connection structure of the hinge assembly 20.

The second rotating member 71 of the first rotating assembly 31 is used to electrically connect the first rotating member 51 and the fixing member 61 at both ends.
