[0004] However, the large screen size increases the size of the electronic device, which makes it inconvenient for users to carry the electronic device with them. To address this problem, electronic devices with foldable screens have gradually come into the user's field of vision. An electronic device with a foldable screen generally includes a housing and a flexible screen attached to the housing, and the housing includes a first housing and a second housing connected by a hinge assembly. Users can adjust the hinge assembly according to their own usage needs to fold or unfold the foldable screen.

[0005] The current hinge assembly is usually a structure combining a slider and a slide groove, and the slider is embedded in the slide groove. By sliding the slider in the slide groove, the hinge assembly drives the angle between the first shell and the second shell to change, thereby realizing the folding or unfolding of the folding screen.

[0076] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0077] The terms used in the following embodiments are only for the purpose of describing specific embodiments, and are not intended to be used as limitations on the present application. As used in the specification and the appended claims of the present application, the singular expressions "one", "a kind of", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context. It should also be understood that in the following embodiments of the present application, "at least one", "one or more" refer to one, two or more. The term "and / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist; for example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0078] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0079] In order to make the description of the following embodiments clear and concise, a brief introduction to the related technology is first given:

[0080] In order to simultaneously meet the user's demand for a large screen and the need for electronic devices to be easy to carry, electronic devices with foldable screens are gradually entering the user's field of vision. The electronic device includes a housing and a flexible screen attached to the housing, and the housing includes a first housing and a second housing connected by a hinge assembly. The user can adjust the hinge assembly according to their own usage needs. As the hinge assembly is adjusted, the angle between the first housing and the second housing changes, and the folding and unfolding of the foldable screen is realized accordingly.

[0081] In a current hinge assembly, two sliders are connected to the first housing, and the two sliders form a double slider structure, which can be used to move the first housing; in addition, the other two sliders of the hinge assembly are connected to the second housing, and form a double slider structure, which is used to move the second housing. The two double slider structures cooperate with each other to realize the folding and unfolding of the folding screen.

[0082] However, in the dual-slider structure, the contact area between the two sliders is large. In order to ensure the smoothness of the folding screen during folding or unfolding, the contact surfaces of the sliders need to achieve high-precision matching. Therefore, a higher manufacturing process is required, the processing cost is high, and the yield of the folding screen is low.

[0083] In addition, since the contact surface of the two sliders in the dual slider structure is large, wear and tear will occur during use. As the electronic device is used for a longer time, the wear and tear will increase day by day, causing the folding screen to become stuck during folding or unfolding during later use of the electronic device, and reducing the service life of the electronic device.

[0084] Another type of hinge assembly is a structure that combines a slider and a slide groove. The slider is embedded in the slide groove. By sliding the slider in the slide groove, the hinge assembly drives the angle between the first shell and the second shell to change, thereby realizing the folding or unfolding of the folding screen.

[0085] Compared with the double slider structure, the structure combining the slider and the slide groove has less wear. However, in order to ensure the smoothness of the folding screen during folding or unfolding and avoid jamming during folding or unfolding, a higher manufacturing process is also required to fine-tune the contact surface of the slider and the slide groove. The requirements for the processing technology are high, which leads to a higher processing cost of the structure and a correspondingly low yield of the folding screen.

[0086] In other words, the hinge components currently used to achieve folding or unfolding of the folding screen require higher processing technology and are relatively costly.

[0087] In order to solve the problem of high processing cost of electronic equipment in the prior art, the present application provides an electronic equipment, which includes a rotating shaft assembly.

In other examples, the angle between the first screen and the second screen can also be other angles, which is not limited in the embodiments of the present application.

[0110] In order to clarify the solution provided by the present application, the solution provided by the present application is introduced and explained through various embodiments in conjunction with the accompanying drawings.

[0111] An embodiment of the present application provides an electronic device, the electronic device comprising a rotating shaft assembly. Figure 3 As shown in the structural schematic diagram, the shaft assembly includes: a shaft bin 300 and two structural components.

[0112] The shaft bin 300 includes a shaft. The two structural components are connected to the two sides of the shaft bin 300 through the shaft included in the shaft bin 300, that is, the two structural components are located on the two sides of the shaft bin 300, one of the structural components is connected to one side of the shaft bin 300, and the other structural component is connected to the other side of the shaft bin 300.

[0113] See also Figure 3 The structural device includes: a swing arm structure 410, a slider 420, a door panel 430 and a door panel connecting rod 440.

[0114] Among them, the swing arm structure 410 is connected to the rotating shaft contained in the rotating shaft bin 300, and rotates with the rotation of the rotating shaft. That is to say, the swing arm structure 410 can achieve rotation coordination with the rotating shaft. When the rotating shaft rotates, the swing arm structure 410 rotates accordingly.

[0115] The slider 420 is connected to the swing arm structure 410 and moves with the rotation of the swing arm structure 410. That is, when the swing arm structure 410 rotates, the slider 420 can be driven to move. In addition, the slider 420 is used to attach to the shell of the electronic device. If the shaft assembly is assembled in the electronic device, the shell of the electronic device is attached to the slider. In this case, when the slider 420 is driven by the swing arm structure 410 to move, the shell of the electronic device also moves accordingly.

[0116] In a feasible design, the slider 420 may be a wedge-shaped slider.

[0117] In addition, in a feasible design, the shell of the electronic device can also be called a structural part of the electronic device. The shell can be the shell or cover of the electronic device. For example, if the electronic device is a mobile phone, the shell of the electronic device can be the battery cover of the mobile phone.

[0118] One side of the door panel 430 is connected to the slider. In this case, when the slider 420 is displaced under the drive of the swing arm structure 410, the door panel 430 will rotate accordingly with the slider 420. In addition, the other side of the door panel 430 is used to attach the folding screen of the electronic device. If the rotating shaft assembly is assembled in the electronic device, the door panel is attached to the folding screen of the electronic device. The display screen of the electronic device may include two screens, namely the first screen and the second screen, wherein the door panel 430 in one structural device can adhere to the first screen, and the door panel 430 in the other structural device can adhere to the second screen. In this case, when the door panel 430 rotates, the first screen or the second screen adhered to the door panel 430 rotates accordingly. That is, when the swing arm structure 410 rotates at the shaft in the shaft bin 300, the door panel 430 rotates accordingly, and drives the first screen or the second screen of the electronic device to rotate accordingly.

[0119] In a feasible design, the door panel 430 can be driven by the rotating shaft to rotate from 0 degrees to 90 degrees.
