The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

The terminology used in the following examples is for the purpose of describing specific embodiments only and is not intended to limit the application.

It should also be understood that in the following embodiments of this application, "at least one" and "one or more" refer to one, two or more than two. The term "and/or" is used to describe the relationship between associated objects, indicating that there can be three relationships; for example, A and/or B can mean: A exists alone, A and B exist simultaneously, and B exists alone, Where A and B can be singular or plural. The character "/" generally indicates that the related objects are in an "or" relationship.

Reference in this specification to "one embodiment" or "some embodiments" or the like means that a particular feature, structure or characteristic described in connection with the embodiment is included in one or more embodiments of the application. Therefore, the phrases "in one embodiment", "in some embodiments", "in other embodiments", "in other embodiments", etc. appearing in different places in this specification are not necessarily References are made to the same embodiment, but rather to "one or more but not all embodiments" unless specifically stated otherwise. The terms “including,” “includes,” “having,” and variations thereof all mean “including but not limited to,” unless otherwise specifically emphasized.

In order to describe the following embodiments clearly and concisely, a brief introduction to related technologies is first given:

In order to simultaneously satisfy users' needs for large-size screens and portability of electronic devices, electronic devices with foldable screens have gradually entered users' field of vision. The electronic device includes a housing and a flexible screen attached to the housing. The housing includes a first housing and a second housing connected through a rotating shaft assembly. Users can adjust the rotating shaft assembly according to their own needs. As the rotating shaft assembly is adjusted, the angle between the first housing and the second housing changes, and the folding screen can be folded and unfolded accordingly.

In a current rotating shaft assembly, two slide blocks are connected to the first housing. The two slide blocks form a double slide block structure and can be used to move the first housing. In addition, the other two slide blocks of the rotating shaft assembly are connected to the second housing. The shells are connected and form a double slider structure for moving the second shell. These two double slider structures cooperate with each other to realize the folding and unfolding of the folding screen.

However, in the double-slider structure, the contact area between the two sliders is large. In order to ensure the smoothness of the folding screen during the folding or unfolding process, the contact surface of the slider needs to achieve high-precision cooperation, so it needs to be relatively small. The manufacturing process is high, the processing cost is high, and the yield rate of folding screens is low.

Moreover, due to the large contact surface of the two sliders in the double slider structure, wear will occur during use. As the use time of electronic devices increases, the wear and tear will increase day by day, causing the folding screen to be prone to jamming during the folding or unfolding process during the later use of the electronic device, and reducing the service life of the electronic device.

Another rotating shaft assembly is a structure that combines a slide block and a chute. The slide block is embedded in the chute. By sliding the slide block in the chute, the rotating shaft assembly drives the angle between the first housing and the second housing. Changes occur to achieve folding or unfolding of the folding screen.

Compared with the double-slider structure, the structure combining the slider and the chute has reduced wear. However, in order to ensure the smoothness of the folding screen during the folding or unfolding process and avoid jamming during the folding or unfolding process, it also needs to be longer. High manufacturing process for slider and The contact surface of the chute needs to be finely machined, which requires high processing technology, which results in higher processing costs for this structure and a lower yield rate for the corresponding folding screen.

In other words, the current rotating shaft components used to realize folding or unfolding of folding screens require relatively high processing technology and high costs.
