[0068] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0069] With the development of science and technology, the appearance (ID) of electronic devices (such as mobile phones, tablet computers, etc.) has a trend of developing from straight-screen phones to folding phones. The folding phone has a large screen in the open state, which fully satisfies the visual experience of consumers. In the closed state, it is small in size and easy to carry. However, the synchronization components in the rotating mechanism of the prior art mostly achieve synchronous movement through synchronization gears, and the complex structure of the synchronization gears will increase the thickness of the rotating mechanism, which is not conducive to simplifying the structure and realizing the lightweight and thinness of foldable electronic devices. The rotating mechanism provided in the present application can achieve the synchronous movement of the synchronization components without setting synchronization gears, which simplifies the structure of the rotating mechanism and is conducive to realizing the lightweight and thinness of foldable electronic devices.

[0074] It should be noted that the angles illustrated in the embodiments of the present application are allowed to have slight deviations. Figure 2 The unfolding angle α of the foldable electronic device 500 shown is 90 degrees, which means that α can be 90 degrees, or approximately 90 degrees, such as 80 degrees, 85 degrees, 95 degrees or 100 degrees.

In this case, the foldable electronic device 500 can include multiple parts, two adjacent parts can be folded relatively close to each other until the foldable electronic device 500 is in a folded state, and two adjacent parts can be unfolded relatively far away until the foldable electronic device 500 is in an unfolded state.

[0076] See also Figure 4 , Figure 4 yes Figure 3 A schematic diagram of the exploded structure of a foldable electronic device 500 is shown.

[0077] The foldable electronic device 500 includes a folding device 200 and a display screen 300, and the display screen 300 is installed on the folding device 200. The display screen 300 includes a display surface 340 and a mounting surface 350, and the display surface 340 and the mounting surface 350 are arranged opposite to each other. The display surface 340 is used to display text, images, videos, etc. The display screen 300 includes a first part 310, a second part 320 and a foldable part 330. The foldable part 330 is located between the first part 310 and the second part 320, and the foldable part 330 can be bent along the Y direction. The first part 310, the second part 320 and the foldable part 330 together constitute the display screen 300. In this embodiment, the display screen 300 adopts a flexible display screen, for example, an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MIL-OLED) display screen, a micro organic light-emitting diode (MIL-LED) display screen, a micro organic light-emitting diode (MIL-LED) display screen, and a quantum dot light emitting diode (QLED) display screen.

[0078] The folding device 200 includes a first housing 210, a second housing 220 and a rotating mechanism 100. The first housing 210 is provided with a first mounting groove 230, and the second housing 220 is provided with a second mounting groove 240. The first mounting groove 230 and the second mounting groove 240 are connected to form a mounting groove. The rotating mechanism 100 is installed in the mounting groove and is fixedly connected to the first housing 210 and the second housing 220 to realize the rotation connection between the first housing 210 and the second housing 220. The first housing 210 and the second housing 220 can rotate relative to each other through the rotating mechanism 100, so that the folding device 200 can switch between the folded state and the unfolded state. The first housing 210 and the second housing 220 are also provided with a receiving groove (not shown), which is used to accommodate electronic components and structural elements such as a processor, a circuit board, and a camera module of the foldable electronic device 500.

[0079] The relative rotation of the first shell 210 and the second shell 220 makes the folding device 200 in the folded state, which means that the first shell 210 and the second shell 220 are rotated by the rotating mechanism 100 and approach each other, and the surfaces of the first shell 210 and the second shell 220 that carry the display screen 300 are opposite. In fact, in the application process, when the folding device 200 is in the fully folded state, after the display screen 300 installed in the first shell 210 and the second shell 220 is folded, the first part 310 and the second part 320 are overlapped and partially contacted, and of course, they can also be fully contacted. The relative rotation of the first shell 210 and the second shell 220 makes the folding device 200 in the semi-expanded state, which means that the first shell 210 and the second shell 220 are rotated by the rotating mechanism 100 and move away from each other, and the angle between the first shell 210 and the second shell 220 is getting larger and larger, which can be close to 90 degrees or equal to 90 degrees. The relative rotation of the first shell 210 and the second shell 220 makes the folding device 200 in the unfolded state, which means that the first shell 210 and the second shell 220 are rotated by the rotating mechanism 100 and move away from each other, and the angle between the first shell 210 and the second shell 220 continues to increase and can be close to 180 degrees or equal to 180 degrees.

[0080] The first shell 210, the second shell 220 and the rotating mechanism 100 are arranged in sequence along the X direction, and the sum of the dimensions between the three is the dimension of the folding device 200 in the X direction (including the assembly tolerance and the assembly gap between the three). The dimension of the folding device 200 in the X direction is the same as the dimension of the display screen 300 and the electronic device in the X direction. Of course, the allowable tolerance range is included. The first shell 210, the second shell 220 and the rotating mechanism 100 have the same dimensions in the Y direction, and the dimensions may allow for assembly or production tolerances. The dimensions of the first shell 210, the second shell 220 and the rotating mechanism 100 in the Y direction are the dimensions of the folding device 200 in the Y direction, and the dimensions of the folding device 200 in the Y direction are the same as the dimensions of the display screen 300 and the foldable electronic device 500 in the Y direction. Of course, a small amount of deviation (assembly and production tolerance) may also be allowed. The display screen 300 is mounted on the folding device 200, and the mounting surface 350 is fixedly connected to the folding device 200. Specifically, the first housing 210 carries the first portion 310, and the second housing 220 carries the second portion 320. In other words, the first portion 310 is mounted on the first housing 210, and the second portion 320 is mounted on the second housing 220. The rotating mechanism 100 is disposed opposite to the foldable portion 330.

[0081] Combination Figure 1, the first housing 210 and the second housing 220 rotate relative to each other through the rotating mechanism 100, and the first housing 210 and the second housing 220 are relatively close to each other to drive the display screen 300 to fold, so that the foldable electronic device 500 is folded. When the foldable electronic device 500 is in the folded state, the foldable portion 330 of the display screen 300 is bent, and the first portion 310 and the second portion 320 are arranged relative to each other. At this time, the display screen 300 is between the first housing 210 and the second housing 220, which can greatly reduce the probability of the display screen 300 being damaged, and effectively protect the display screen 300.

[0082] Please also read Figure 2 and Figure 4 , the first shell 210 and the second shell 220 rotate relative to each other through the rotating mechanism 100, and the first shell 210 and the second shell 220 move away from each other to drive the display screen 300 to unfold, so that the foldable electronic device 500 is unfolded to a semi-expanded state. When the foldable electronic device 500 is in a semi-expanded state, the first shell 210 and the second shell 220 unfold to an angle of α, the first part 310 and the second part 320 unfold relative to each other, and drive the foldable part 330 to unfold. At this time, the angle between the first part 310 and the second part 320 is α. In this embodiment, α is 90 degrees. In other embodiments, α may also be approximately 90 degrees, or 80 degrees, 85 degrees, 95 degrees, or 100 degrees, etc.

[0083] Please also read Figure 3 and Figure 4 , the first shell 210 and the second shell 220 rotate relative to each other through the rotating mechanism 100, and the first shell 210 and the second shell 220 move away from each other to drive the display screen 300 to further unfold until the foldable electronic device 500 unfolds. When the folding device 200 is in the unfolded state, the angle between the first shell 210 and the second shell 220 is β. The foldable part 330 unfolds, and the first part 310 and the second part 320 unfold relatively. At this time, the angles between the first part 310, the second part 320 and the foldable part 330 are all β, and the display screen 300 has a large display area, realizing a large-screen display of the foldable electronic device 500 and improving the user experience. In this embodiment, β is 180 degrees. In other embodiments, β may also be approximately 180 degrees, and may be 0 degrees, 5 degrees, 185 degrees, 190 degrees, etc.

Furthermore, when the fixed plate 20 and the auxiliary fixed plate 30 rotate relative to the fixed base 10, they also jointly drive the pressure plate 40 to rotate relative to the fixed base 10, thereby driving the pressure plate swing arm 90 to rotate relative to the fixed base 10, and causing the pressure plate swing arm 90 to resist or release the floating plate 1, so that the floating plate 1 moves in the Z direction relative to the fixed base 10, thereby realizing the rotation of the rotating mechanism 100 to achieve the bending of the display screen 300.
