[0040] To make the objectives, features, and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present disclosure.

[0041] The embodiment of the present application provides an electronic device, and the electronic device can be any device including a rotating shaft. As long as it is an electronic device that needs to be flipped, it can be included within the scope of the embodiment of the present application. For example: laptop computers, folding screen mobile phones, tablet computers with rotating keyboards, servers, all-in-one computers, etc.

[0042] Combined with Figure 1 ,Figure 6 and Figure 8 As shown in Figure 8 , the electronic device provided by the embodiment of the present disclosure may include a first body 1, a second body 2, and a rotating shaft mechanism 3. The first body 1 and the second body 2 form two parts of the electronic device that can be opened and closed. The first body 1 is movably connected to the second body 2 through the rotating shaft mechanism 3, and the rotating shaft mechanism 3 enables the first body 1 and the second body 2 to move relative to each other, such as folding or unfolding. Among them, the first body 1 and the second body 2 may be components connected to the rotating shaft mechanism 3 respectively, and the rotating shaft mechanism 3 can drive the first body 1 to rotate towards or away from the second body 2 to realize the opening and closing of the electronic device. Taking the electronic device as a laptop computer as an example, the first body may be a screen assembly, and the second body may be a host assembly.

[0043] The rotating shaft mechanism 3 includes a first rotating shaft 31, a second rotating shaft 32, and a third rotating shaft 33 that are rotatably connected to each other. The first body 1 includes a first housing, and the second body 2 includes a second housing. In a state where the first housing and the second housing are parallel, along the projection in the vertical direction of the first housing, the projection of the first body 1 covers the projection of the first rotating shaft 31 and the projection of the second rotating shaft 32 and / or; and / or, along the projection in the vertical direction of the first housing, the projection of the second body 2 covers the projection of the first rotating shaft 31 and / or the projection of the second rotating shaft 32.

On the one hand, this embodiment can form a new appearance structure. On the other hand, it can reduce the size of the part of the rotating shaft mechanism 3 located outside the first body 1 and the second body 2, reduce the installation space of the rotating shaft mechanism 3 outside the first body 1 and the second body 2, make the electronic device small, thin and portable, and can meet the user's requirements for the shape of the electronic device.
