[0043] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below with reference to the drawings and examples.

[0044] In the prior art, a foldable terminal generally comprises a flexible screen, an external communication antenna arranged on the flexible screen and used for signal transmission between the flexible screen and the outside world, and an electrically controlled structure arranged on the flexible screen and used for internal signal transmission of the flexible screen. The flexible screen comprises a first folding part, an intermediate bending part and a second folding part connected in sequence. The electrically controlled structure can be a plurality of circuit mainboards arranged in the first folding part and the second folding part respectively. The electrically controlled structure on the first folding part and the electrically controlled structure of the second folding part generally perform signal transmission through a communication carrier such as a flexible circuit board and a radio frequency signal line as a physical wiring to realize signal interconnection between the first folding part and the second folding part. With an increase in the number of bending times of the flexible screen, the physical wiring will have a certain loss, causing a decrease in mechanical strength and thus affecting the transmission performance between the circuit mainboards.

[0045] The application provides a folding device, comprising a folding body 10, a first wireless communication chip 21, a second wireless communication chip 22, a first electrically controlled structure 23, a second electrically controlled structure 24, a first radiator 25, a second radiator 26, a support assembly 30, a cladding medium 40 and a shielding layer 50.

[0046] Please refer to Figure 1 and Figure 4 . The folding body 10 comprises a first folding part 11, an intermediate bending part 13 and a second folding part 12 connected in sequence. The intermediate bending part 13 is a bendable structure. When the intermediate bending part 13 is bent, the first folding part 11 and the second folding part 12 can be arranged at an angle or can be parallel to each other, as shown in Figure 5 . When the intermediate bending part 13 is unfolded, the first folding part 11, the second folding part 12 and the intermediate bending part 13 are all located on the same plane, i.e. the folding body 10 is in a flat state, as shown in Figure 6 . In this embodiment, the folding body 10 can be a flexible screen or other carrier mechanism.

[0047] Please refer to Figure 1 and Figure 4 . The first folding part 11 is provided with the first wireless communication chip 21, and the second folding part 12 is provided with the second wireless communication chip 22. The first folding part 11 and the second folding part 12 perform wireless communication through the first wireless communication chip 21 and the second wireless communication chip 22. Specifically, a rotation space corresponding to the intermediate bending part 13 is formed between the first wireless communication chip 21 and the second wireless communication chip 22. The first wireless communication chip 21 and the second wireless communication chip 22 form a wireless communication link in the rotation space, so that the first folding part 11 and the second folding part 12 realize wireless communication.

[0048] The folding device is provided with the first wireless communication chip 21 and the second wireless communication chip 22, so that the first folding part 11 and the second folding part 12 can communicate wirelessly through the first wireless communication chip 21 and the second wireless communication chip 22, that is, the wireless communication mode replaces the traditional physical wiring for internal signal transmission. When the folding body 10 is frequently bent, the wireless communication mode reduces the loss of the communication carrier and ensures the transmission performance between the first folding part 11 and the second folding part 12.

[0049] The traditional communication carrier is physical wiring, and the transmission mode through physical wiring will increase the number of physical wiring with the increase of transmission signals, occupy the rotation space, increase the cost, and increase the loss of physical wiring. The folding device realizes the transmission of bus signals between multiple control mainboards through wireless signals, and the increase of transmission signals will not occupy the rotation space, improves the rate and capacity of signal transmission efficiency, and has expandability to accommodate the gradually increasing number of bus signals.

[0050] The first electric control structure 23, the first wireless communication chip 21 and the first radiator 25 are sequentially and electrically connected to the first folding part 11, and the second electric control structure 24, the second wireless communication chip 22 and the second radiator 26 are sequentially and electrically connected to the second folding part 12. The first electric control structure 23 and the second electric control structure 24 each include a plurality of control mainboards. The first wireless communication chip 21 aggregates bus signals or / and radio frequency signals of the plurality of control mainboards on the first folding part 11 and converts the bus signals or / and radio frequency signals into first wireless signals. The second wireless communication chip 22 aggregates bus signals or / and radio frequency signals of the plurality of control mainboards on the second folding part 12 and converts the bus signals or / and radio frequency signals into second wireless signals. In this way, the first electric control structure 23 and the second electric control structure 24 realize wireless transmission of internal signals of the folding device through coupling of the first wireless signals and the second wireless signals.

[0051] Please refer to Figure 1 and Figure 4The support assembly 30 is used for supporting the folding body 10, and comprises a first support plate 31, a rotating shaft 33 and a second support plate 32 connected in sequence. The first support plate 31 is rotatably connected with the second support plate 32 through the rotating shaft 33. The first support plate 31 is connected with and supports the first folding part 11. The second support plate 32 is connected with and supports the second folding part 12. The rotating shaft 33 corresponds to the middle bending part 13 and is located in the rotating space. In the embodiment, the first support plate 31 and the second support plate 32 are both flat plates and are used for ensuring the flatness of the flexible screen or other carrier mechanisms. In this way, the flexible screen is prevented from collapsing when a user touches the flexible screen. Meanwhile, the first folding part 11 and the second folding part 12 are also prevented from being bent. The first support plate 31 and the second support plate 32 can be adjusted in the included angle therebetween when rotating relative to the rotating shaft 33. The first support plate 31 and the second support plate 32 can be folded to be opposite to each other. At this time, the first folding part 11 and the second folding part 12 can be located on the sides opposite to the first support plate 31 and the second support plate 32 respectively or on the sides facing each other of the first support plate 31 and the second support plate 32 respectively. The rotating shaft 33 improves the strength and stability of the middle bending part 13 and reduces the pulling of the folding body 10 on the middle bending part 13 when the folding body 10 is used. When the conventional physical wiring is used for signal transmission, the physical wiring needs to pass through the rotating shaft 33, thereby occupying the internal space of the rotating shaft 33 and reducing the strength of the rotating shaft 33. The folding device realizes signal interconnection in a wireless communication mode, without the physical wiring passing through the rotating shaft 33 and without the connection between the physical wiring and the first electric control structure 23 and the second electric control structure 24, thereby improving the integrity of the rotating shaft 33, ensuring the strength and stability of the rotating shaft 33 and reducing the complexity of the processing of the rotating shaft 33. In the case of a large number of bending times, the wear of the rotating shaft 33 is also reduced, and the communication performance is prevented from deteriorating. The rotating shaft 33 can be fixedly connected with one of the first support plate 31 or the second support plate 32 and rotatably connected with the other, but this will cause the first support plate 31 and the second support plate 32 to be unable to be folded to be parallel to each other. In the embodiment, the cross section of the rotating shaft 33 is substantially oval, and has two rotating axes arranged in parallel and spaced apart. The first support plate 31 and the second support plate 32 rotate relative to one rotating axis, so that the first support plate 31 and the second support plate 32 with a certain thickness can be overlapped. Alternatively, the rotating shaft 33 is divided into two sides by a line between the two rotating axes. The wall surface of one side is an outward convex arc surface, and the wall surface of the other side is a plane. The first support plate 31 and the second support plate 32 rotate toward the side of the rotating shaft 33 with the plane, so as to avoid the rotating shaft 33 limiting the rotating angle of the first support plate 31 or the second support plate 32. The folding body 10 is located on the side of the rotating shaft 33 with the arc surface, so that the bending range of the middle bending part 13 is relatively gentle, the folding damage degree of the folding body 10 is reduced, and the service life of the folding body 10 is prolonged.The first support plate 31 and the second support plate 32 can be directly connected with the rotating shaft 33, or can be connected through other structures or media.

[0052] Please refer to Figure 1 and Figure 4 The first wireless communication chip 21 is used for transmitting the bus signal or / and the radio frequency signal of the first electric control structure 23 to the first radiator 25, the second wireless communication chip 22 is used for transmitting the bus signal or / and the radio frequency signal of the second electric control structure 24 to the second radiator 26, and the first wireless communication chip 21 and the second wireless communication chip 22 perform wireless communication through the first radiator 25 and the second radiator 26.

[0053] The bus signal is transmitted through the flexible circuit board, and the radio frequency signal is transmitted through the radio frequency signal line. The first wireless communication chip 21 aggregates and converts the bus signal and the radio frequency signal to be transmitted by the first electric control structure 23 into high-frequency millimeter wave signals of the first radiator 25, and performs wireless transmission towards the second radiator 26, and the second wireless communication chip 22 aggregates and converts the bus signal and the radio frequency signal to be transmitted by the second electric control structure 24 into high-frequency millimeter wave signals of the second radiator 26, and performs wireless transmission towards the first radiator 25. Thus, a wireless communication link is established inside the folding device through the first radiator 25 and the second radiator 26, so as to replace the physical wiring for signal transmission, to transmit high-frequency signals at a high speed, and to realize wireless transmission of the bus signal between the first electric control structure 23 and the second electric control structure 24.

[0054] In one embodiment, please refer to Figure 1 The first radiator 25 and the second radiator 26 are arranged on the rotating shaft 33 and are spaced apart. The first wireless communication chip 21 aggregates and converts the bus signal and / or the radio frequency signal to be transmitted by the first electric control structure 23 into high-frequency millimeter wave signals of the first radiator 25, and performs wireless transmission inside the rotating shaft 33, and the second wireless communication chip 22 aggregates and converts the bus signal and / or the radio frequency signal to be transmitted by the second electric control structure 24 into high-frequency millimeter wave signals of the second radiator 26, and performs wireless transmission inside the rotating shaft 33. Thus, a wireless communication link inside the rotating shaft 33 is established through the first radiator 25 and the second radiator 26 on both sides of the rotating shaft 33, so as to replace the physical wiring for signal transmission, to transmit high-frequency signals at a high speed, and to realize wireless transmission of the bus signal between the first electric control structure 23 and the second electric control structure 24. When the first radiator 25 and the second radiator 26 are arranged on the rotating shaft 33, the distance between them is shortened, and the rotating shaft 33 can also be used as a medium to promote signal transmission, thereby improving the transmission speed between the first radiator 25 and the second radiator 26.

[0055] Please refer toFigure 2 As an embodiment, the first radiator 25 and the second radiator 26 can be millimeter wave antennas, and the two millimeter wave antennas can wirelessly communicate through millimeter wave signals to achieve high-performance transmission of signals under the condition of short distance and low power. The millimeter wave antenna can be composed of a metal sheet, can be a flexible circuit board partially inserted into the rotating shaft 33, or can be a conductive layer formed on the rotating shaft 33 by spraying or printing process. The millimeter wave antenna has strong compatibility with the rotating shaft 33, can make the best use of the space of the rotating shaft 33, that is, the millimeter wave antenna has good conformality with the rotating shaft 33, does not need to significantly increase the space of the structure of the rotating shaft 33, and does not affect the structural stability of the rotating shaft 33.

[0056] Please refer to Figure 3 As another embodiment, the first radiator 25 and the second radiator 26 are both slot antennas formed by slotting the rotating shaft 33. Specifically, one or several slot-shaped slots are formed on the two sides of the rotating shaft 33 in the radial direction to form slot antennas, and the slot antennas are electrically connected to the first wireless communication chip 21 and the second wireless communication chip 22 on the two sides, respectively. Each slot antenna can form a slot radiation to couple signals to radiate or receive internal transmitted wireless signals. Each slot antenna extends along the axial direction of the rotating shaft 33 and can be formed at the same height or different heights. The slot antenna also has strong compatibility with the rotating shaft 33, can make the best use of the space of the rotating shaft 33, that is, the slot antenna has good conformality with the rotating shaft 33, does not need to occupy too much space of the structure of the rotating shaft 33, and does not affect the structural stability of the rotating shaft 33. In order to ensure the stable wireless transmission performance of the foldable device at different opening angles, the antenna performance in different use states needs to be considered, or the radiation structure needs to be designed at different positions of the rotating shaft 33.

[0057] Please refer to Figure 4 In another embodiment, the first radiator 25 is integrated in the first wireless communication chip 21, and the second radiator 26 is integrated in the second wireless communication chip 22. The first wireless communication chip 21 is arranged at a position close to the rotating shaft 33 of the first folding part 11, the first radiator 25 is arranged at a position close to the rotating shaft 33 of the first wireless communication chip 21, the second wireless communication chip 22 is arranged at a position close to the rotating shaft 33 of the second folding part 12, and the second radiator 26 is arranged at a position close to the rotating shaft 33 of the second wireless communication chip 22. In this way, the first radiator 25 and the second radiator 26 do not occupy the internal structural space of the rotating shaft 33, do not affect the structure of the rotating shaft 33, improve the stability of the rotating shaft 33, and facilitate the assembly of the folding device and the replacement of components.

[0058] Please refer to Figure 5 and Figure 6In order to improve the signal transmission performance between the first radiator 25 and the second radiator 26, the covering medium 40 is covered on the first radiator 25 and the second radiator 26, so that the first radiator 25 and the second radiator 26 transmit signals through the covering medium 40, which promotes signal interconnection and accelerates transmission speed. The covering medium 40 also covers the rotating shaft 33, and the covering medium 40 ensures the stability of the wireless signal transmission inside the rotating shaft 33 device. In the embodiment, the covering medium 40 is a non-metallic material, such as plastic, air, etc. The first support plate 31 and the second support plate 32 can be connected to the rotating shaft 33 through the covering medium 40. At this time, the covering medium 40 is made of a flexible material. The covering medium 40 enhances the connection between the first radiator 25, the second radiator 26, and the rotating shaft 33 or its carrier, improves the mechanical strength, and avoids the first radiator 25 and the second radiator 26 from being broken or the electrical connection between the first wireless communication chip 21 and the second wireless communication chip 22 from being poor.

[0059] Please refer to Figure 5 and Figure 6 In order to prevent signal leakage of the first radiator 25 and the second radiator 26, a shielding layer 50 is arranged on the outer layer of the covering medium 40. The shielding layer 50 is used to isolate the signals in the covering medium 40 from external signals, so as to prevent the millimeter wave signals emitted or received by the first radiator 25 and the second radiator 26 from being interfered or interfering other signals, and to ensure stable transmission in different folding states. The shielding layer 50 can be covered on the outer layer of the covering medium 40, or can be arranged in the area of the covering medium 40 which does not contact other components in the folding device. The shielding layer 50 can be a metal coating, or a flexible or rigid metal structural member. The shielding layer 50 can adopt different architectural schemes according to different rotating shaft 33 structures to adapt to the structural requirements and ensure the bus transmission performance.

The folding device has the same structural features as the folding device in each of the above embodiments and the same functions, which will not be described here. The folding body 10 can be a flexible screen or other carrier structure, and the terminal device can be a mobile phone, a tablet computer, etc. with a flexible screen.

[0061] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
