[0003] With the development of foldable device technology (such as foldable phones), various manufacturers have launched a variety of foldable devices in different shapes and sizes. However, foldable devices on the market are relatively bulky and heavy when in use. How to provide a terminal device that is lightweight and thin when in use, easy to carry when not in use, and has a large display area when unfolded is a challenge that the industry needs to address.

The flexible screen is fixed to the same side of the first folding portion and the second folding portion. The first device is detachably mounted on the second device. When the first device is mounted on the second device, the side of the first folding portion facing away from the flexible screen abuts against the second surface or the screen portion.

[0007] The terminal device provided in this application embodiment includes a first device detachably mounted on a second device. A screen portion is provided on the first surface of the housing portion of the first device. A first folding portion and a second folding portion of the second device are connected by a first pivot. A flexible screen is provided on the same side of the first folding portion and the second folding portion. After detaching the first device from the second device, the user can use the first device without picking up the second device, making the first device relatively thin and light during use. When not in use, the first and second folding portions of the second device can be folded, and the first device can be mounted on the second device, resulting in a compact overall structure that is easy to carry. When the second device is mounted on the first device and the housing portion is stacked on the first folding portion, or when the second device is detached from the first device, unfolding the first and second folding portions allows the flexible screen to unfold, providing a large display area.

[0110] The terminal devices provided in this application embodiment can be mobile phones, tablet computers, laptop computers, e-book readers, netbooks, personal digital assistants, etc.

[0111] See Figures 1 to 7This application provides a terminal device 1, including a first device 10 and a second device 20. The first device 10 includes a housing portion 11 and a screen portion 12. The housing portion 11 has a first surface 11a and a second surface 11b that are opposite to each other along the thickness direction. The screen portion 12 is fixed to the first surface 11a. The second device 20 includes a first folding portion 21, a second folding portion 21a, a first pivot 22, and a flexible screen 23. The first folding portion 21 and the second folding portion 21a are connected by the first pivot 22, so that the first folding portion 21 can be folded or unfolded relative to the second folding portion 21a. The flexible screen 23 is fixed to the same side of the first folding portion 21 and the second folding portion 21a. The first device 10 is detachably mounted on the second device 20. When the first device 10 is mounted on the second device 20, the side of the first folding portion 21 that is opposite to the flexible screen 23 abuts against the second surface 11b (or the screen portion 12).

[0112] The first device 10 can be in the form of a candybar phone. A circuit board, battery, receiver, speaker, camera, and / or other devices can be mounted on the housing 11. The screen 12 can be a rigid screen or a flexible screen. The screen 12 can be an organic light-emitting diode (OLED) screen.

[0113] The second device 20 can be foldable. The first folding section 21 and the second folding section 21a serve as a housing, where circuit boards, batteries, receivers, speakers, cameras, and / or other devices can be mounted. The first pivot 22 can be referred to as a hinge assembly. The known first pivot 22 enables the opening and closing movement of the two folding sections, i.e., the two folding sections fold or unfold. The flexible screen 23 is a bendable flexible screen, such as an OLED screen or an active matrix organic light-emitting diode (AMOLED) screen.

[0114] The terminal device 1 provided in this application embodiment has a first device 10 detachably mounted on a second device 20. A screen portion 12 is provided on the first surface 11a of the housing portion 11 in the first device 10. A first folding portion 21 and a second folding portion 21a in the second device 20 are connected by a first pivot 22. A flexible screen 23 is provided on the same side of the first folding portion 21 and the second folding portion 21a. After the first device 10 is detached from the second device 20, the user can use the first device 10 without picking up the second device 20, making the first device 10 relatively thin and light. When not in use, the first folding portion 21 and the second folding portion 21a of the second device 20 can be folded, and the first device 10 can be mounted on the second device 20, resulting in a compact overall structure that is easy to carry. When the second device 20 is mounted on the first device 10 and the housing portion 11 is stacked on the first folding portion 21, or when the second device 20 is detached from the first device 10, unfolding the first folding portion 21 and the second folding portion 21a allows the flexible screen 23 to unfold, providing a large display area.

[0115] To achieve a communication connection and / or electrical connection between the first device 10 and the second device 20, in some embodiments, see [reference needed]. Figures 8 to 12 The first device 10 has a first interface terminal 13, and the second device 20 has a second interface terminal 24. The first interface terminal 13 and the second interface terminal 24 can be communicatively connected and / or electrically connected. By cooperating with the first interface terminal 13 of the first device 10 and the second interface terminal 24 of the second device 20, the first device 10 and the second device 20 can be communicatively connected, enabling the transmission of predetermined electrical signals between the first device 10 and the second device 20. Furthermore, the first interface terminal 13 and the second interface terminal 24 can be electrically connected, enabling the transmission of electrical energy between the first device 10 and the second device 20.

[0116] For example, the first device 10 has a first main chip 14, and the second device 20 has a camera module 26. Combined Figure 11 The second device 20 is in a flattened state, and the first device 10 is mounted on the second device 20. The camera module 26 of the second device 20 captures the scene and obtains an image signal. The image signal needs to be transmitted to the first main chip 14 of the first device 10 for processing. The first interface terminal 13 of the first device 10 and the second interface terminal 24 of the second device 20 are connected to communicate, so that the image signal can be transmitted from the second device 20 to the first device 10.

[0117] For example, the first device 10 has a first battery, and the second device 20 has a second battery. The first interface terminal 13 and the second interface terminal 24 cooperate to realize the reverse charging function between the first device 10 and the second device 20. For example, if the first battery of the first device 10 has less power, the power of the second battery of the second device 20 can be transferred to the first battery through the electrical connection of the first interface terminal 13 and the second interface terminal 24.

[0118] For example, the first device 10 has a first circuit board, and a first interface terminal 13 is electrically connected to the first circuit board. The second device 20 has a second circuit board, and a second interface terminal 24 is electrically connected to the second circuit board. The first interface terminal 13 and the second interface terminal 24 are communicatively connected and / or electrically connected, which enables the first circuit board and the second circuit board to be communicatively connected and / or electrically connected.

[0119] There are several possible implementation methods when setting the first interface terminal 13 and the second interface terminal 24. Two implementation methods are given as examples below.

[0120] The first implementation method for the first interface terminal 13 and the second interface terminal 24: see [link / reference] Figures 8 to 11 The first interface end 13 is located on the side of the housing portion 11 that abuts against the first folding portion 21, and the second interface end 24 is located on the side of the first folding portion 21 that faces away from the flexible screen 23. The first interface end 13 and the second interface end 24 can be plugged into each other for communication and / or electrical connection. The side of the housing portion 11 that abuts against the first folding portion 21 is the side of the housing portion 11 that abuts against the first folding portion 21 when the first device 10 is assembled with the second device 20.

[0121] The first interface terminal 13 and the second interface terminal 24 employ a wired communication connection and / or wired charging method via plug-in terminals. When the first device 10 is installed on the second device 20, the first interface terminal 13 and the second interface terminal 24 are plugged in to achieve communication connection and / or wired charging between the first device 10 and the second device 20. The positions of the first interface terminal 13 and the second interface terminal 24 correspond, ensuring that the length and width dimensions of the first device 10 and the second device 20 are similar when the first device 10 is installed on the second device 20, resulting in a compact overall structure. Both the first interface terminal 13 and the second interface terminal 24 can be used for charging, power supply, and data transmission. Both the first interface terminal 13 and the second interface terminal 24 can be connected to a wired charger to achieve wired charging of the first device 10 and the second device 20, respectively.

[0122] For example, the first device 10 is installed on the second device 20, and the first interface end 13 and the second interface end 24 are plugged into each other to achieve a communication connection, enabling the first main chip 14 on the first device 10 and the flexible screen 23 of the second device 20 to communicate and realize the predetermined electrical signal transmission between the first main chip 14 and the flexible screen 23. For example, combined with Figure 11The flexible screen 23 has a touch layer. Users can activate a predetermined program or command by operating the touch layer, which will then transmit a signal to the first main chip 14, which will call the predetermined program or command. Alternatively, after the first main chip 14 executes the predetermined program or command, it will return a signal to the flexible screen 23, which will then display a predetermined image or interface.

[0123] The second implementation method for the first interface terminal 13 and the second interface terminal 24: See [link / reference] Figures 8 to 11 The first interface terminal 13 and the second interface terminal 24 are connected via wireless communication and / or radio connection. Both the first interface terminal 13 and the second interface terminal 24 can be used with a wireless charger to enable wireless charging of the first device 10 and the second device 20, respectively.

[0124] When configuring the first interface terminal 13 and the second interface terminal 24 for wireless communication connection, the first interface terminal 13 and the second interface terminal 24 are respectively the first antenna and the second antenna that can communicate with each other, so as to realize the wireless communication between the first device 10 and the second device 20.

[0125] The first and second antennas can use 60 GHz millimeter-wave communication technology, optical communication technology, or terahertz communication technology to achieve wireless communication between the first device 10 and the second device 20, such as enabling ultra-large data streams and low-latency data transmission for the camera module.

[0126] For example, the first device 10 is assembled on the second device 20, and the first interface terminal 13 and the second interface terminal 24 are connected by wireless communication. The image signal obtained by the camera module 26 on the second device 20 is transmitted to the first device 10 wirelessly and processed by the high-performance first main chip 14 on the first device 10.

[0127] When configuring the first interface terminal 13 and the second interface terminal 24 for wireless connection, the first interface terminal 13 and the second interface terminal 24 are respectively a first coil and a second coil that can be coupled to each other. The first coil in the first device 10 is electrically connected to the first battery, and the second coil in the second device 20 is electrically connected to the second battery. By placing the first coil and the second coil close together, the user can set the direction of power transmission, thereby enabling wireless reverse charging between the first device 10 and the second device 20.

[0128] Understandably, in order to achieve a communication connection between the first device 10 and the second device 20, in some embodiments, the first device 10 and the second device 20 may use either a wired communication method or a wireless communication method. In other embodiments, the first device 10 and the second device 20 may be configured with both wired and wireless communication methods, so that some signals are transmitted through wired communication and other signals are transmitted through wireless communication.

[0129] To enable reverse charging between the first device 10 and the second device 20 via electrical connection, in some embodiments, the first device 10 and the second device 20 can be charged individually using either wired charging or wireless charging. In other embodiments, both wired and wireless charging can be configured between the first device 10 and the second device 20, allowing the user to choose the appropriate charging method as needed.

[0130] There are several possible implementation methods for achieving the detachable connection between the first device 10 and the second device 20. Two implementation methods are given below as examples.

[0131] The first method for detachably connecting the first device 10 and the second device 20: see [link / reference] Figure 8 , Figure 9 The first folding part 21 and the housing part 11 are detachably connected by a magnetic attraction assembly 40. The magnetic attraction assembly 40 includes a first magnetic attraction member 41 and a second magnetic attraction member 42. The first magnetic attraction member 41 is disposed on the housing part 11, and the second magnetic attraction member 42 is disposed on the first folding part 21. The first magnetic attraction member 41 and the second magnetic attraction member 42 can magnetically attract each other.

[0132] The use of magnetic assemblies 40 facilitates the detachable connection between the first folding portion 21 and the housing portion 11, offering high reliability and minimizing damage. When the housing portion 11 and the side of the first folding portion 21 facing away from the flexible screen 23 are close together, the first magnetic assemblies 41 and 42 magnetically engage, causing the housing portion 11 to adhere to the first folding portion 21. When it is necessary to disassemble the housing portion 11 and the first folding portion 21, a predetermined force is applied to overcome the magnetic attraction of the first magnetic assemblies 41 and 42, allowing the housing portion 11 to separate from the first folding portion 21.

[0133] For example, one of the first magnetic attracting member 41 and the second magnetic attracting member 42 can be a magnet, and the other can be a magnetic conductor, such as a structure made of magnetic materials such as silicon steel, pure iron, and low carbon steel, and the magnet and the magnetic conductor can magnetically attract each other.

[0134] For example, the first magnetic member 41 and the second magnetic member 42 are both magnets, and the first magnetic member 41 on the first folding part 21 and the second magnetic member 42 on the housing part 11 are configured to magnetically engage.

[0135] The first magnetic chuck 41 can be disposed at any position on the housing portion 11, and the second magnetic chuck 42 is disposed on the first fold portion 21 at the position corresponding to the first magnetic chuck 41. The number of the first magnetic chuck 41 and the second magnetic chuck 42 can be set as needed, and there can be one or more of them.

[0136] The second method for detachably connecting the first device 10 and the second device 20 is as follows: the first folding part 21 and the housing part 11 are detachably connected by a snap-fit ​​assembly. The snap-fit ​​assembly includes a snap-fit ​​part and a snap-fit ​​groove. One of the snap-fit ​​part and the snap-fit ​​groove is located in the first folding part 21, and the other is located in the housing part 11. The snap-fit ​​part and the snap-fit ​​groove can be engaged.

[0137] A snap-fit ​​assembly facilitates the detachable connection of the first folding part 21 and the housing part 11. When assembling the housing part 11 and the first folding part 21, aligning the snap-fit ​​parts and fastening them into the slots secures the housing part 11 to the first folding part 21. When separating the housing part 11 and the first folding part 21, applying a predetermined force disengages the snap-fit ​​parts from the slots, allowing the housing part 11 to separate from the first folding part 21. The snap-fit ​​parts and slots can be arranged in pairs to ensure a stable connection between the first device 10 and the second device 20.

[0138] To facilitate the positioning of the housing portion 11 on the first fold portion 21, in some embodiments, see [reference needed]. Figure 1 , Figure 2 , Figure 8 , Figure 9 The housing portion 11 has a boss portion 111 on the side that abuts against the first folding portion 21. The inner cavity of the boss portion 111 provides ample space for mounting predetermined components. This side of the housing portion 11 that abuts against the first folding portion 21 is the side where the housing portion 11 abuts against the first folding portion 21 when the first device 10 is assembled with the second device 20. The side of the first folding portion 21 facing away from the flexible screen 23 has a recess portion 211, into which the boss portion 111 can be fitted. This allows the housing portion 11 to be easily and quickly positioned at a predetermined position on the first folding portion 21, improving assembly efficiency.

[0139] The boss portion 111 can be located in the middle of one side of the housing portion 11, so that more space is reserved inside the boss portion 111 to install more predetermined devices. Correspondingly, the recess portion 211 is provided in the middle of the first fold portion 21, so that the boss portion 111 can be fitted into the recess portion 211.

[0140] For example, the boss portion 111 may be located at the middle of the length direction and the middle of the width direction of the housing portion 11. This can be understood as forming the boss portion 111 by thinning a ring around the housing portion 11. Correspondingly, the recessed portion 211 is provided at the middle of the length and width directions of the first folded portion 21, and the recessed portion 211 is frame-shaped. This allows the boss portion 111 to be positioned and assembled into the recessed portion 211.

[0141] For example, the boss portion 111 may be located at the middle of the width direction of the housing portion 11, and the boss portion 111 extends to one end (or both ends) of the housing portion 11 along the length direction. Correspondingly, the recess portion 211 is provided at the middle of the width direction of the first fold portion 21, and the recess portion 211 extends through one end (or both ends) of the first fold portion 21 along the length direction. This allows the boss portion 111 to be positioned and assembled in the recess portion 211.

[0142] In some embodiments, see Figure 8 The boss 111 of the housing portion 11 can be fitted into the recess 211 of the first folding portion 21. The first folding portion 21 has a receiving portion 212 for accommodating the first rotating shaft 22, and the thickness D1 of the receiving portion 212 is greater than the thickness D2 of the recess 211. The receiving portion 212 can accommodate the connecting first rotating shaft 22, and the first folding portion 21 and the second folding portion 21a can be relatively unfolded or folded through the first rotating shaft 22. The thickness D1 of the receiving portion 212 is the distance of the receiving portion 212 in the thickness direction of the first folding portion 21. The thickness D2 of the recess 211 is the distance of the recess 211 in the thickness direction of the first folding portion 21.

[0143] For example, see Figure 8 , Figure 9 The boss portion 111 is located on the second surface 11b of the housing portion 11. When the first device 10 is assembled into the second device 20, the boss portion 111 is fitted into the recess 211 of the first fold portion 21, and the screen portion 12 is exposed.

[0144] For example, see Figure 13 , Figure 14 The boss portion 111 is located on the first surface 11a of the housing portion 11. When the first device 10 is assembled with the second device 20, the side of the first folding portion 21 facing away from the flexible screen 23 abuts against the screen portion 12. The boss portion 111 is fitted into the recess 211 of the first folding portion 21, and the screen portion 12 is covered by the housing portion 11. At this time, the screen portion 12 is not visible from the outside.

[0145] In order to enable the first device 10 to have more functions, in some embodiments, see [reference] Figure 15 , Figure 16 The first interface terminal 13 can be communicatively and / or electrically connected to the third interface terminal 31 of the predetermined functional device 30, which includes a camera module, an artificial intelligence module, a graphics processor module, and / or a heat dissipation module. By utilizing the communicative and / or electrical connection between the first interface terminal 13 of the first device 10 and the third interface terminal 31 of the predetermined functional device 30, the first device 10 can be expanded to have more functions.

[0146] The communication and / or electrical connection between the first interface terminal 13 and the third interface terminal 31 can be referenced from the communication and / or electrical connection between the first interface terminal 13 and the second interface terminal 24 described above. The communication connection can be a wired or wireless communication connection. The electrical connection can be a wired or wireless connection.

[0147] In the case where the predetermined functional device 30 is a camera module, the first device 10 is separated from the second device 20. The third interface terminal 31 of the camera module and the first interface terminal 13 of the first device 10 are communicatively and electrically connected. The first main chip 14 of the first device 10 drives the external camera module to work, and the first battery of the first device 10 supplies power to the camera module, enhancing the shooting capability of the first device 10. Existing camera module and interface technologies can be used to achieve this.

[0148] The predetermined functional device 30 is an artificial intelligence (AI) module. The first device 10 is separated from the second device 20. The third interface terminal 31 of the AI ​​module and the first interface terminal 13 of the first device 10 are communicatively and electrically connected. The first main chip 14 of the first device 10 drives the external AI module, and the first battery of the first device 10 supplies power to the AI ​​module, enhancing the AI ​​capabilities of the first device 10. Existing AI modules and interface technologies can be used to implement this.

[0149] The predetermined functional device 30 is a graphics processing unit (GPU) module. The first device 10 is separated from the second device 20. The third interface terminal 31 of the GPU module and the first interface terminal 13 of the first device 10 are communicatively and electrically connected. The first main chip 14 of the first device 10 drives the external GPU module to work, and the first battery of the first device 10 supplies power to the GPU module, thereby enhancing the graphics computing capabilities of the first device 10. Existing GPU modules and interface technologies can be used to implement this.

[0150] The predetermined functional component 30 is a heat dissipation module. The first device 10 is separated from the second device 20. The heat dissipation module is electrically connected to the first interface terminal 13 of the first device 10. The first battery of the first device 10 supplies power to the external heat dissipation module, which dissipates heat from the first device 10, thereby enhancing the heat dissipation capacity of the first device 10. The heat dissipation module can be in the form of a fan or the like.

[0151] When implementing the detachable connection between the first device 10 and the predetermined functional device 30, the previously described methods for implementing the detachable connection between the first device 10 and the second device 20 can be referenced, namely, magnetic attraction and snap-fit ​​connection. Figure 15 , Figure 16In the embodiment shown, the first device 10 has a first magnetic 41, and the predetermined functional device 30 has a third magnetic 43. The first magnetic 41 and the third magnetic 43 can magnetically engage, which facilitates the detachable connection of the first device 10 and the predetermined functional device 30.

[0152] To facilitate the positioning of the housing portion 11 on the predetermined functional device 30, the engagement method of the boss portion 111 of the first device 10 and the recess portion 211 of the second device 20 can be referenced. Figure 15 , Figure 16 In the illustrated embodiment, the housing portion 11 has a boss portion 111, and the predetermined functional device 30 has a recess portion 32, with the boss portion 111 capable of being fitted into the recess portion 32. This allows the predetermined functional device 30 to be conveniently and quickly positioned at a predetermined position in the first device 10, thereby improving assembly efficiency.

[0153] There are several possible implementation methods when setting up the second device 20. The second device 20 can be in a three-fold or two-fold form. Several implementation methods are given as examples below.

[0154] The first implementation method of the second device 20: see [link / reference] Figures 1 to 12 The second device 20 includes a first folding portion 21, a second folding portion 21a, a first pivot 22, and a flexible screen 23. The first folding portion 21 and the second folding portion 21a are connected by the first pivot 22, allowing the first folding portion 21 to fold or unfold relative to the second folding portion 21a. The second device 20 also includes a third folding portion 21b and a second pivot 22a. The first pivot 22 and the second pivot 22a are located on opposite sides of the first folding portion 21, and the first folding portion 21 and the third folding portion 21b are connected by the second pivot 22a, allowing the third folding portion 21b to fold or unfold relative to the first folding portion 21. The flexible screen 23 is fixed to the same side of the first folding portion 21, the second folding portion 21a, and the third folding portion 21b. The second pivot 22a can be referred to as a hinge assembly. The known second pivot 22a enables the opening and closing movement of the two folding portions, i.e., the folding or unfolding of the two folding portions.

[0155] The aforementioned second device 20 adopts a three-fold configuration. The second fold 21a is connected to one side of the first fold 21 via a first pivot 22, and the third fold 21b is connected to the other side of the first fold 21 via a second pivot 22a. During the opening and closing movements of the first fold 21 and the second fold 21a, the flexible screen 23 can unfold and bend in sync with the first fold 21, the second fold 21a, and the first pivot 22. During the opening and closing movements of the first fold 21 and the third fold 21b, the flexible screen 23 can unfold and bend in sync with the first fold 21, the third fold 21b, and the second pivot 22a.

[0156] See Figure 4, Figure 10 The second device 20 is in a flattened state, with the second fold 21a, the first fold 21, and the third fold 21b arranged sequentially along the flattening direction. The second fold 21a is flattened relative to the first fold 21, and the two folds are approximately 180° apart. The third fold 21b is flattened relative to the first fold 21, and the two folds are approximately 180° apart. This allows the flexible screen 23 to be flattened to provide a large display area.

[0157] See Figure 1 , Figure 8 When the second device 20 is in the closed state, the second folding part 21a folds relative to the first folding part 21, and the third folding part 21b folds relative to the first folding part 21. The first folding part 21, the second folding part 21a and the third folding part 21b form a stacked structure, and the overall structure is compact.

[0158] A first pivot 22 between the first fold 21 and the second fold 21a maintains a predetermined angle between the first fold 21 and the second fold 21a. A second pivot 22a between the first fold 21 and the third fold 21b maintains a predetermined angle between the first fold 21 and the third fold 21b. Figure 12 In the embodiment shown, the first fold 21 and the second fold 21a are flattened, and the third fold 21b and the first fold 21 are at a predetermined angle.

[0159] For example, see Figures 8 to 12 The first pivot 22 and the second pivot 22a are located on opposite sides of the first folding portion 21. The first pivot 22 is an inward folding pivot, and the second pivot 22a is an inward folding pivot; combined with Figure 8 When the second device 20 is in the closed state, the second fold 21a is located between the first fold 21 and the third fold 21b. The first fold 21, the second fold 21a, and the third fold 21b are stacked sequentially, resulting in a compact overall structure that is easy to carry.

[0160] For example, see Figure 17 , Figure 18 The first rotating shaft 22 is an inward folding rotating shaft, and the second rotating shaft 22a is an inward folding rotating shaft; when the second device 20 is in the closed state, the third folding part 21b is located between the first folding part 21 and the second folding part 21a. The first folding part 21, the third folding part 21b, and the second folding part 21a are stacked sequentially, resulting in a compact overall structure that is easy to carry.

[0161] The inner folding hinge is a known type of hinge that can realize the relative folding or unfolding of the two folding parts. When the two folding parts are closed, the flexible screen 23 bends along with the two folding parts and is located between the two folding parts.

[0162] The second implementation method of the second device 20: see [link / reference] Figure 19 , Figure 20 The second device 20 includes a first folding portion 21, a second folding portion 21a, a first pivot 22, and a flexible screen 23. The first folding portion 21 and the second folding portion 21a are connected by the first pivot 22, allowing the first folding portion 21 to fold or unfold relative to the second folding portion 21a. The second device 20 also includes a third folding portion 21b and a second pivot 22a. The first pivot 22 and the second pivot 22a are located on opposite sides of the first folding portion 21, and the second folding portion 21a and the third folding portion 21b are connected by the second pivot 22a, allowing the third folding portion 21b to fold or unfold relative to the second folding portion 21a. The flexible screen 23 is fixed to the same side of the first folding portion 21, the second folding portion 21a, and the third folding portion 21b. The second pivot 22a can be referred to as a hinge assembly. The known second pivot 22a enables the opening and closing movement of the two folding portions, i.e., the folding or unfolding of the two folding portions.

[0163] The aforementioned second device 20 adopts a three-fold configuration. The first fold 21 is connected to one side of the second fold 21a via a first pivot 22, and the third fold 21b is connected to the other side of the second fold 21a via a second pivot 22a. During the opening and closing movements of the first fold 21 and the second fold 21a, the flexible screen 23 can unfold and bend in sync with the first fold 21, the second fold 21a, and the first pivot 22. During the opening and closing movements of the second fold 21a and the third fold 21b, the flexible screen 23 can unfold and bend in sync with the second fold 21a, the third fold 21b, and the second pivot 22a.

[0164] See Figure 20 The second device 20 is in a flattened state, with the first fold 21, the second fold 21a, and the third fold 21b arranged sequentially along the flattening direction. The first fold 21 is flattened relative to the second fold 21a, and the first fold 21 and the second fold 21a are approximately 180° apart. The third fold 21b is flattened relative to the second fold 21a, and the second fold 21a and the third fold 21b are approximately 180° apart. This allows the flexible screen 23 to be flattened to provide a large display area.

[0165] See Figure 19 When the second device 20 is in the closed state, the first folding part 21 is folded relative to the second folding part 21a, and the third folding part 21b is folded relative to the second folding part 21a. The first folding part 21, the second folding part 21a and the third folding part 21b form a stacked structure, and the overall structure is compact.

[0166] The first pivot 22 between the first fold 21 and the second fold 21a can maintain a predetermined angle between the first fold 21 and the second fold 21a. The second pivot 22a between the second fold 21a and the third fold 21b can maintain a predetermined angle between the second fold 21a and the third fold 21b.

[0167] For example, see Figure 19 , Figure 20 The first rotating shaft 22 is an inward folding rotating shaft, and the second rotating shaft 22a is an inward folding rotating shaft; when the second device 20 is in the closed state, the third folding part 21b is located between the first folding part 21 and the second folding part 21a. The first folding part 21, the third folding part 21b, and the second folding part 21a are stacked sequentially, resulting in a compact overall structure that is easy to carry.

[0168] For example, see Figure 21 , Figure 22 The first rotating shaft 22 is an inward folding rotating shaft, and the second rotating shaft 22a is an outward folding rotating shaft. When the second device 20 is in the closed state, the second folding part 21a is located between the first folding part 21 and the third folding part 21b. The first folding part 21, the second folding part 21a, and the third folding part 21b are stacked sequentially, resulting in a compact overall structure that is easy to carry.

[0169] The outward folding hinge is a known type of hinge that can realize the relative folding or unfolding of the two folding parts. When the two folding parts are closed, the flexible screen 23 bends along with the two folding parts and is located on the outside of the two folding parts.

[0170] The third implementation method of the second device 20: see [link / reference] Figure 23 , Figure 24 The second device 20 includes a first folding part 21, a second folding part 21a, a first rotating shaft 22, and a flexible screen 23. The first folding part 21 and the second folding part 21a are connected by the first rotating shaft 22, so that the first folding part 21 can be folded or unfolded relative to the second folding part 21a.

[0171] The second device 20 described above adopts a double-fold form, with the second fold 21a connected to the first fold 21 via a first pivot 22. During the opening and closing movements of the first fold 21 and the second fold 21a, the flexible screen 23 can unfold and bend in tandem with the first fold 21, the second fold 21a, and the first pivot 22.

[0172] See Figure 24 The second device 20 is in a flattened state, with the first fold 21 and the second fold 21a arranged along the flattening direction. The second fold 21a is flattened relative to the first fold 21, and the first fold 21 and the second fold 21a are approximately 180° apart, so that the flexible screen 23 is flattened to provide a large display area.

[0173] See Figure 23 When the second device 20 is in the closed state, the second folding part 21a is folded relative to the first folding part 21, and the first folding part 21 and the second folding part 21a form a stacked structure, resulting in a compact overall structure.

[0174] The first pivot 22 between the first fold 21 and the second fold 21a can maintain a predetermined included angle between the first fold 21 and the second fold 21a.

[0175] In order to enable the first device 10 and the second device 20 to have camera functions, in some embodiments, see [reference]. Figures 8 to 11 The first device 10 has a first camera module 15, and the second device 20 has a second camera module 26. When the first device 10 and the second device 20 are disassembled, the first camera module 15 of the first device 10 and the second camera module 26 of the second device 20 can be used individually for shooting. (See also...) Figure 11 When the first device 10 is assembled on the second device 20, the second device 20 is in a flattened state, and the second camera module 26 of the second device 20 can be used for shooting.

[0176] For example, the first camera module 15 of the first device 10 may include a first front-facing camera and a first rear-facing camera. The first front-facing camera is located on the same side of the screen portion 12 on the housing portion 11. The first rear-facing camera is located on the opposite side of the screen portion 12 on the housing portion 11. The first rear-facing camera may protrude from the surface of the housing portion 11, and the protrusion distance may be less than 1 mm.

[0177] For example, the second camera module 26 of the second device 20 may include a second front-facing camera and a second rear-facing camera. The second front-facing camera is located on one of the folded portions of the second device 20 and is disposed on the same side as the flexible screen 23. The second rear-facing camera is located on one of the folded portions of the second device 20 and is located on the opposite side of the flexible screen 23.

[0178] In some embodiments, multiple cameras with different focal lengths are arranged on the same side of the terminal device 1 to achieve shooting at different focal lengths or in different scenes. The multiple cameras may include a main camera, as well as at least one of a telephoto camera, a wide-angle camera, and a macro camera. Typically, the multiple cameras with different focal lengths are arranged adjacent to each other.

[0179] When multiple cameras with different focal lengths are arranged on the same side of terminal device 1, there are several possible implementation methods. Two implementation methods are given as examples below.

[0180] The first method for implementing multiple cameras with different focal lengths arranged on the same side of the terminal device 1: See [link / reference] Figures 25 to 27 The first camera module 15 includes multiple first cameras 151 with the same light-receiving side but different focal lengths; combined with Figure 26When the second device 20 is in a closed state and the first device 10 is mounted on the second device 20, the first folding part 21 and the first camera 151 are located on opposite sides of the thickness direction of the first device 10.

[0181] Multiple first cameras 151 with different focal lengths are mounted on the first device 10. When the first device 10 is mounted on the second device 20 and the second device 20 is in a closed state, the first cameras 151 do not affect the assembly of the first device 10 and the second device 20. Figure 27 When the first device 10 is installed on the second device 20 and the second device 20 is in a flattened state, the flexible screen 23 and the first camera 151 are located on opposite sides of the assembly structure of the housing part 11 and the first folding part 21, respectively. The multiple first cameras 151 serve as rear cameras, and the flexible screen 23 can display the scene captured by the first camera 151.

[0182] For example, in Figures 25 to 27 In this embodiment, the second device 20 has a three-fold configuration, with the first hinge 22 being an inward-folding hinge and the second hinge 22a being an outward-folding hinge. When the second device 20 is in the closed state, the second fold portion 21a is located between the first fold portion 21 and the third fold portion 21b. When the first device 10 is assembled into the second device 20, the side of the first fold portion 21 facing away from the flexible screen 23 abuts against the screen portion 12. The screen portion 12 is covered by the housing portion 11, so it is not visible from the outside. A plurality of first cameras 151 are disposed on the opposite side of the screen portion 12 of the housing portion 11, i.e., the second surface 11b. Figure 27 Multiple first cameras 151 serve as rear cameras, and the flexible screen 23 can display the scene captured by the first cameras 151.

[0183] For example, in Figures 28 to 30 In this embodiment, the second device 20 has a three-fold configuration, with the first hinge 22 being an inward-folding hinge and the second hinge 22a being an outward-folding hinge. When the second device 20 is in the closed state, the second fold portion 21a is located between the first fold portion 21 and the third fold portion 21b. The first camera 151 and the screen portion 12 are respectively disposed in different areas of the first surface 11a of the housing portion 11. For example, the rectangular first surface 11a is divided into upper and lower areas, with multiple first cameras 151 of different focal lengths disposed in the upper area of ​​the first surface 11a, and the screen portion 12 disposed in the lower area of ​​the first surface 11a. Figure 30 Multiple first cameras 151 serve as rear cameras, and the flexible screen 23 can display the scene captured by the first cameras 151.

[0184] The second type of terminal device 1 implements multiple cameras with different focal lengths arranged on the same side: See [link / reference] Figures 8 to 11The second camera module 26 includes multiple second cameras 261 with the same incident light side but different focal lengths; combined with Figure 9 When the second device 20 is in the closed state, the first fold 21 and the second camera 261 are located on opposite sides of the thickness direction of the second device 20.

[0185] Multiple second cameras 261 with different focal lengths are mounted on the second device 20. See also Figure 9 When the first device 10 is mounted on the second device 20 and the second device 20 is in a closed state, the second camera 261 does not affect the folding of the multiple folding parts in the second device 20, nor does it affect the assembly of the first device 10 and the second device 20. (See reference...) Figure 10 , Figure 11 When the second device 20 is in a flattened state, the flexible screen 23 and the second camera 261 are located on opposite sides of the second fold 21a (or the third fold 21b), and the multiple second cameras 261 serve as rear cameras, allowing the flexible screen 23 to display the scene captured by the second cameras 261.

[0186] For example, in Figures 8 to 11 In the embodiment, the second device 20 has a tri-fold shape, see reference. Figure 10 The second device 20 is in a flattened state, with the second fold 21a, the first fold 21, and the third fold 21b arranged sequentially along the flattening direction. Multiple second cameras 261 can be located on the side of the third fold 21b facing away from the flexible screen 23. (See reference...) Figure 9 When the second device 20 is in a closed state, the first fold 21, the second fold 21a and the third fold 21b are stacked in sequence, and the multiple second cameras 261 are located on the side of the third fold 21b away from the second fold 21a.

[0187] For example, in Figure 19 , Figure 20 In the embodiment, the second device 20 has a tri-fold shape, see reference. Figure 20 The second device 20 is in a flattened state, with the first fold 21, the second fold 21a, and the third fold 21b arranged sequentially along the flattening direction. (See reference...) Figure 19 When the second device 20 is in the closed state, the first fold 21, the third fold 21b, and the second fold 21a are stacked in sequence, and the multiple second cameras 261 are located on the side of the second fold 21a away from the third fold 21b.

[0188] For example, in Figure 23 , Figure 24 In the embodiment, the second device 20 is in a bi-fold form, see reference. Figure 23When the second device 20 is in the closed state, the multiple second cameras 261 are located on the side of the second fold 21a away from the first fold 21.

[0189] In order to enable the first main chip 14 and the second main chip 25 to have computing capabilities, in some embodiments, see [reference]. Figures 8 to 11 The first device 10 has a first main chip 14, and the second device 20 has a second main chip 25. When the first device 10 and the second device 20 are separated, they perform predetermined computational processing through their respective main chips.

[0190] For example, the first device 10 has a first circuit board, on which a first main chip 14 is disposed. The first circuit board may be disposed within the housing portion 11. The second device 20 has a second circuit board, on which a second main chip 25 is disposed. The second circuit board may be disposed in at least one fold portion of the second device 20.

[0191] For example, the second device 20 includes a first folding portion 21, a second folding portion 21a, and a third folding portion 21b. The second circuit board includes a first sub-board, a second sub-board, and a third sub-board. The first sub-board, the second sub-board, and the third sub-board can be disposed one-to-one in the first folding portion 21, the second folding portion 21a, and the third folding portion 21b. Two adjacent sub-boards can be connected by a flexible plate passing through the corresponding pivot, or two adjacent sub-boards can be connected wirelessly.

[0192] To enable communication between the first device 10 and the second device 20, in some embodiments, see [reference needed]. Figures 8 to 11 The first device 10 has a mobile cellular antenna 16 and a short-range antenna 16a; the second device 20 has a short-range antenna 27. When the first device 10 and the second device 20 are disassembled, the mobile cellular antenna 16 and the short-range antenna 16a of the first device 10, and the short-range antenna 27 of the second device 20 can all be used independently to achieve communication functions.

[0193] The mobile cellular antenna 16 is an antenna that supports mobile cellular communication technology. It may include a mobile cellular antenna with mid-to-high frequency parasitic antennas and a mobile cellular antenna with low-frequency parasitic antennas. The mid-to-high frequency band may range from 1000 MHz to 3000 MHz. The low-frequency band may range below 1000 MHz.

[0194] Short-range antennas can include antennas for various short-range communication technologies such as Global Positioning System (GPS), Wireless Fidelity (WIFI), and Bluetooth (BT) modules.

[0195] For example, both the first device 10 and the second device 20 have WIFI antennas. The first main chip 14 on the first device 10 has stronger computing power. When the second device 20 has a high computing power requirement, it can transmit the signal of the second device 20 to the first device 10 through the WIFI antenna, and the first main chip 14 will perform data processing.

[0196] For example, the first device 10 has a first circuit board disposed within the housing portion 11, and the first circuit board integrates a mobile cellular antenna 16 and a short-range antenna 16a. The second device 20 has a second circuit board, which may be disposed in at least one fold portion of the second device 20, and the second circuit board integrates a short-range antenna 27.

[0197] In other embodiments, the first device 10 has a short-range antenna 16a; the second device 20 has a mobile cellular antenna and a short-range antenna 27. When the first device 10 and the second device 20 are disassembled, the short-range antenna 16a of the first device 10 and the mobile cellular antenna and short-range antenna 27 of the second device 20 can each be used independently to achieve communication functions. Furthermore, the first device 10 may also have a mobile cellular antenna.

[0198] In some embodiments, to enable the first device 10 and the second device 20 to have electrical power, the first device 10 has a first battery and the second device 20 has a second battery. The electrical components on the first device 10 can be powered by the first battery, which is disposed within the housing portion 11. The electrical components on the second device 20 can be powered by the second battery, which can be disposed as needed within different folds of the second device 20.

[0199] To ensure a compact overall structure when the first device 10 is assembled with the second device 20, in some embodiments, see [reference needed]. Figures 1 to 3 The first device 10 is in the shape of a rectangular plate, and the second device 20 in the closed state is also in the shape of a rectangular plate. The length L1 of the housing portion 11 and the length L2 of the second device 20 in the closed state are adapted to each other, and the width W1 of the housing portion 11 and the width W2 of the second device 20 in the closed state are adapted to each other. The rectangular plate-shaped first device 10 and the second device 20 allow for rounded corners at the edges of the rectangular plates.

[0200] Matching lengths (or widths) of two structural components means that their dimensions are close to or equal. When the second device 20 is in a closed state and the first device 10 is assembled into the second device 20, the lengths (or widths) of the first device 10 and the second device 20 are relatively close, resulting in a compact overall structure that is easy to store and has a good appearance.

[0201] The screen portion 12 is generally rectangular, and its shape is adapted to the shape of the housing portion 11. The flexible screen 23 is generally rectangular, and its shape is adapted to the shape of the flattened second device 20.

[0202] In some embodiments, see Figures 31 to 36 The thickness D3 of the first folding portion 21 can be less than the thickness D4 of the second folding portion 21a. This allows the total thickness of the second device 20 in the closed state to be relatively small, resulting in a compact overall structure, smaller footprint, and easier portability for the user. The second folding portion 21a has a larger internal space to accommodate thicker components such as the camera module 26.

[0203] In some embodiments, see Figure 35 , Figure 36 The thickness D3 of the first folded portion 21 is less than the thickness D4 of the second folded portion 21a. When the second device 20 is in the closed state, the flexible screen 23 is bent near the first pivot 22, and the bent portion 23a of the flexible screen 23 is positioned close to the second folded portion 21a. A larger portion of the bent portion 23a of the flexible screen 23 is biased towards the second folded portion 21a, while a smaller portion is located within the first folded portion 21. Using the contact surface between the first folded portion 21a and the second folded portion 21a as a reference surface, the bent portion 23a of the flexible screen 23 forms an asymmetrical teardrop shape, which effectively protects the bent portion 23a of the flexible screen 23 and reduces the likelihood of creases forming on the bent portion 23a of the flexible screen 23 after long-term bending and use.

[0204] In other embodiments, see Figure 1 , Figure 2 , Figure 8 , Figure 23 The thickness of the first fold 21 and the thickness of the second fold 21a are close to or equal. Devices can be arranged inside both the first fold 21 and the second fold 21a.

[0205] When the second device 20 is in the closed state, using the contact surface between the first fold 21 and the second fold 21a as a reference surface, the bent portion 23a of the flexible screen 23 is approximately in a symmetrical teardrop shape. That is, one part of the bent portion 23a of the flexible screen 23 is inside the first fold 21, and the other part is inside the second fold 21a. Moreover, the areas where the two parts of the bent portion 23a enter the two folds are relatively close. This effectively protects the bent portion 23a of the flexible screen 23 and reduces the likelihood of creases forming on the bent portion 23a of the flexible screen 23 after long-term bending and use.

[0206] In some embodiments, see Figures 31 to 36The side of the housing portion 11 that abuts against the first folding portion 21 is flat and has no protrusion. The side of the first folding portion 21 facing away from the flexible screen 23 is flat and has no recess. When the first device 10 is assembled onto the second device 20, the housing portion 11 of the first device 10 abuts against the first folding portion 21 of the second device 20. The first folding portion 21 and the housing portion 11 are detachably connected, which can be achieved by means of... Figure 8 , Figure 9 This can be achieved through magnetic components or snap-fit ​​components, as shown.

[0207] Finally, it should be noted that the above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
