Example 1

An embodiment of the present invention discloses an electronic device, as shown in fig. 1 to 10, including: the folding device comprises a first machine body 1, a second machine body 2 and a rotary folding device 3, wherein the first machine body 1 and the second machine body 2 are connected with the rotary folding device 3. In the present application, the first body 1 may be a keyboard, the second body 2 may be a display screen, and a host component of a computer is integrated on the first body 1; the connection between the second body 2 (also the display screen) and the rotary folding device 3 may be a detachable connection, specifically, a magnetic connection or a snap connection, so that the display screen may be detached from the electronic device main body to flexibly display the display content thereon.

Referring to fig. 3 and 4, there is shown a schematic structural diagram of a rotary folding apparatus 3 according to the present invention, as shown in fig. 3 and 4, which includes: a first rotating body 31, a second rotating body 32, a rotating shaft mechanism 33, and a third rotating body 34. The first rotating body 31 is connected with the first body 1, and the third rotating body 34 is connected with the second body 2.

Specifically, the first rotating body 31 and the second rotating body 32 are connected by a rotating shaft mechanism 33. In the present application, the rotating shaft mechanism 33 may be any one of the conventional ones as long as it can realize the rotation and opening of the second rotating body 32 with respect to the first rotating body 31, and the structure thereof is not particularly limited.

Specifically, referring to fig. 5, the second rotating body 32 has a plurality of sliding rails 321, the third rotating body 34 has a plurality of sliding blocks 341 disposed corresponding to the sliding rails 321, the sliding blocks 341 can slide in the corresponding sliding rails 321 in a reciprocating manner (i.e., the third rotating body 34 is connected to the second rotating body 32), and when the sliding blocks 341 slide in the corresponding sliding rails 321, an angle on the bottom side of the third rotating body 34 slides along the bottom side of the second rotating body 32, and an included angle between the bottom side of the third rotating body 34 and the bottom side of the second rotating body 32 changes (as shown in fig. 4).

In the present application, based on the limitation formed by the connection between the plurality of sliding rails 321 and the plurality of corresponding sliding blocks 341, the degree that "one angle on the bottom side of the third rotating body 34 slides along the bottom side of the second rotating body 32, and the included angle between the bottom side of the third rotating body 34 and the bottom side of the second rotating body 32 changes" needs to be reached, therefore, the number of the sliding rails 321 and the sliding blocks 341 is two or more, and the track of the sliding rail 321 can be set according to the requirement of the actual application scenario, as long as the sliding rail 321 and the corresponding sliding block 341 can reach the above limitation, which is not specifically limited herein.

In the present application, the limitation of the variable range of the included angle between the bottom side of the third rotating body 34 and the bottom side of the second rotating body 32 can be realized by setting the length and the shape of the track, specifically, the initial rotation state of the rotating and folding device 3 generally refers to a state when the included angle between the bottom side of the third rotating body 34 and the bottom side of the second rotating body 32 is 0 degree (that is, a state when the display screen in the electronic device is a landscape screen), and the maximum rotation state of the rotating and folding device 3 can be set according to the requirements of specific application scenarios, for example, in order to meet the requirement for using a portrait screen of the display screen in the electronic device, the maximum rotation state can be a state when the included angle between the bottom side of the third rotating body 34 and the bottom side of the second rotating body 32 is 90 degrees, and of course, the included angle between the bottom side of the third rotating body 34 and the bottom side of the second rotating body 32 can also be a state when the included angle is greater than 90 degrees, such as 110 degrees, 120 degrees, 130 degrees, etc.

In the present application, in order to improve the neat symmetry of the appearance of the electronic device in all the usage states, the rotating and folding device 3 may be further configured to make the third rotating body 34 located in the middle of the second rotating body 32 (i.e. the display screen located in the middle of the second rotating body 32) when the third rotating body is in the maximum rotation state where the included angle between the bottom edge of the third rotating body 34 and the bottom edge of the second rotating body 32 is 90 degrees.

In the present application, in order to protect the display screen connected to the third rotating body 34 by the second rotating body 32 in the rotating and folding device 3 when the electronic device is in the closed state, the third rotating body 34 in the rotating and folding device 3 may be limited such that the third rotating body 34 is located between the second rotating body 32 and the first rotating body 31 when the second rotating body 32 is rotated and closed with respect to the first rotating body 31.

As a specific embodiment, as shown in fig. 5 to 9, there may be three slide rails 321 and the sliding block 341, and the slide rail 321 includes a vertical slide rail and two curved slide rails, and the vertical slide rail is located between the two curved slide rails; and the curved sliding rails may be two completely separated sliding rails (as shown in fig. 5 to 7) or two sliding rails having an intersection point (as shown in fig. 8), at this time, because the time points at which the sliding blocks 341 corresponding to the two curved sliding rails reach the intersection point are completely different, the third rotating body 34 may still rotate normally because there is no rotational interference. Specifically, fig. 5-7 respectively show state structure diagrams of the electronic device when the sliding rail 321 includes a vertical sliding rail and two curved sliding rails, and the two curved sliding rails 321 are two completely separated sliding rails, and the included angles between the bottom edge of the third rotating body 34 and the bottom edge of the second rotating body 32 are 0 degree, 30 degrees, and 90 degrees.

As a specific embodiment, as shown in fig. 9, there may be three sliding rails 321 and three sliding blocks 341, but the three sliding rails 321 may also be curved sliding rails.

As a specific embodiment, the connection between the sliding block 341 and the corresponding sliding rail 321 may be a detachable connection (which is a specific implementation manner of the detachable connection between the third rotating body 34 and the second rotating body 32), for example, the end portion of the sliding block 341 away from the third rotating body 34 may be provided with a buckle, when the sliding block 341 is connected with the corresponding sliding rail 321, the buckle is clamped in a correspondingly arranged clamping slot in the sliding rail 321, or when the sliding rail 321 penetrates through the second rotating body 32, the sliding block 341 penetrates the sliding rail 321 and the buckle is clamped at two sides of the sliding rail 321. At this time, when it is necessary to detach the display screen from the entire electronic apparatus, it may also be achieved by releasing the connection between the slider 341 and the corresponding slide rail 321 (instead of only by releasing the connection between the display screen and the third rotating body 34).

As a specific embodiment, the plurality of sliding blocks 341 may further include a plurality of movable sliding blocks 341a detachably connected to the third rotating body 34, specifically, all the sliding blocks 341 may be the movable sliding blocks 341a (actually, another specific implementation manner in which the third rotating body 34 and the second rotating body 32 are detachably connected), or only a part of the sliding blocks 341 may be the movable sliding blocks 341 a; when all the sliders 341 are movable sliders 341a, if the display screen needs to be detached from the entire electronic device, the connection relationship between the third rotating body 34 and the movable sliders 341a may be released; when some of the sliders 341 are movable sliders 341a, the other sliders 341 except the movable slider 341a may be detachably connected to the corresponding slide rails 321, and in this case, the connection between the third rotating body 34 and the movable slider 341a may be released, and the connection between the other sliders 341 except the movable slider 341a and the corresponding slide rails 321 may be released (in practice, a specific manner of releasing the connection between the third rotating body 34 and the second rotating body 32 may be still implemented).

As a specific embodiment, when the movable sliding blocks 341a are present, in order to limit the relative position between the movable sliding blocks 341a, so as to prevent the situation that the position of one or more movable sliding blocks 341a is changed, which results in that the third rotating body 34 cannot normally rotate after restoring the connection with the second rotating body 32, and only after all the sliding blocks 341 are restored to the position of the third rotating body 34 in the initial state (when the third rotating body 34 is in the initial state, all the sliding blocks 341 are generally located at the end of the sliding rail 321, and at this time, the relative position between the sliding blocks 341 is correct), the third rotating body 34 can be restored to the connection with the second rotating body 32 and normally rotate, which is a problem of poor convenience in use, as shown in fig. 10, the rotary folding device 3 may further include a limit link 35, the limit link 35 is disposed on the wall surface of the second rotating body 32 far from the third rotating body 32, two ends of the limit link 35 are respectively connected to the two movable sliders 341a, and the relative positions of all the movable sliders 341a are limited by the limit link 35. Specifically, the number of the limit links 35 is set according to the number of the movable sliders 341a, and fig. 10 shows a case where there are two movable sliders 341a and one limit link 35 is provided.
