[0002] With the rapid development of flexible screen technology, foldable electronic devices such as foldable screen mobile phones are becoming more and more popular among consumers. Foldable electronic devices generally include a hinge mechanism, an inner screen and two middle frames. The hinge mechanism contains a door panel structure for supporting the inner screen. The two middle frames are respectively arranged on both sides of the hinge mechanism and connected to the hinge mechanism. The inner screen covers the middle frame and the hinge mechanism.

DETAILED DESCRIPTION

[0177] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0178] In order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and the like are used to distinguish the same items or similar items with substantially the same functions and effects. For example, the first swing arm and the second swing arm are used to distinguish different swing arms, and the order thereof is not limited. Those skilled in the art can understand that the words "first", "second" and the like do not limit the quantity and position, and the words "first", "second" and the like do not necessarily limit the difference.

[0179] It should be noted that, in this application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplarily" or "for example" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in a specific way.

[0180] A foldable electronic device generally includes a hinge mechanism, an inner screen and two middle frames. The hinge mechanism contains a door panel structure for supporting the inner screen. The two middle frames are respectively arranged on both sides of the hinge mechanism and are connected to the hinge mechanism. The inner screen covers the middle frame and the hinge mechanism. The hinge mechanism drives the middle frame to rotate, thereby realizing the folding or flattening of the foldable electronic device. With the development of foldable electronic devices, their thickness has gradually decreased. Correspondingly, the hinge mechanism and the door panels contained therein also need to be thinned. Therefore, how to reduce the thickness of the hinge mechanism and the door panels while ensuring the rotation stability of the hinge mechanism is a technical problem faced by technicians in this field. In order to solve the above technical problems, an embodiment of the present application provides an electronic device.

[0181] The electronic device (electronic device) provided in the embodiment of the present application may be a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), or other foldable mobile terminal products with a flexible screen. The embodiment of the present application does not limit the specific type of the electronic device.

[0182] For the convenience of explanation, the following embodiments take the electronic device as a foldable mobile phone as an example to illustrate the structure of the electronic device.

[0183] like Figure 1 and Figure 2 As shown, Figure 1 Schematic diagram of the structure of an electronic device according to an embodiment of the present application (in a flattened state), Figure 2 Schematic diagram of the structure of an electronic device of an embodiment of the present application (folded state), the embodiment of the present application proposes an electronic device, the electronic device includes a flexible screen 30, two middle frames 20 and a hinge mechanism 10; the hinge mechanism 10 includes a base 100 and two door panel assemblies 300 respectively arranged on both sides of the base 100; the two middle frames 20 are respectively arranged on both sides of the hinge mechanism 10, and are connected to the door panels of the two door panel assemblies 300 ( Figure 1 The two door panel assemblies 300 drive the two middle frames 20 to rotate toward each other or away from each other around the base 100, so that the electronic device is in a folded state or a flattened state; the flexible screen 30 covers the hinge mechanism 10 and the middle frame 20.

[0184] The two middle frames 20 of the electronic device are connected by a hinge mechanism 10, and the two middle frames 20 are relatively rotated by the hinge mechanism 10, so as to realize the folding and flattening of the electronic device. The structures of the two middle frames 20 can be the same or not completely the same, and the specific structures of the two middle frames 20 can be determined according to the specific product, and this application does not make specific limitations on this.

[0185] In the embodiment of the present application, the two middle frames 20 can rotate toward each other or rotate away from each other under the drive of the hinge mechanism 10, so that the electronic device is in a folded state or a flattened state. Figure 1 As shown, when the hinge mechanism 10 is in a flattened state, the two middle frames 20 located on both sides of the hinge mechanism 10 are also in a flattened state, so that the electronic device is in a flattened state; Figure 2 As shown, when the hinge mechanism 10 is in a folded state, the two middle frames 20 located on both sides of the hinge mechanism 10 are also in a folded state, that is, the two middle frames 20 located on both sides of the hinge mechanism 10 overlap, so that the electronic device is in a folded state.

[0186] The flexible screen 30 includes two fixed parts and a bent part. The two fixed parts can be combined and fixed with the two middle frames 20. The bent part is arranged relative to the main shaft body of the hinge mechanism 10, and the two are not fixed to meet the requirement of bending and deformation of the bent part when folded. When the electronic device is in a folded state, the bent part can be curved in an arc shape. In this way, the R angle of the inward fold of the screen is large enough and will not withstand a large degree of bending, while the fixed parts on both sides can fit well without leaving gaps, while minimizing the bending marks. Of course, when the flexible screen 30 is in a closed state, the folding shape of the bent part may not be limited to the water drop type described in this article, but may also be other forms.

[0187] The flexible screen 30 includes a display module and a transparent cover plate. The display module can display images and videos, etc. The display module can use a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active matrix organic light-emitting diode or an active matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), Miniled, MicroLed, Micro-oLed, a quantum dot light emitting diode (QLED), etc. The transparent cover plate covers the outside of the display module to protect the display module. The transparent cover plate can be a glass cover plate, or of course, it can be other transparent materials that can play a protective function. The flexible screen 30 can also have a touch function, that is, the flexible screen 30 can be a touch screen.
