Specifically, the electronic device provided by the embodiment of the present invention may be an intelligent display terminal device, for example, a mobile phone, a tablet computer, a display screen, an intelligent game machine, and the like. The first body 1 and the second body 2 may both be plate-shaped structures, so that the first body 1 and the second body 2 can be conveniently carried after being relatively rotated and folded, or the first body 1 and the second body 2 may also have other special solid geometric structures, but it is required to ensure that the first body 1 and the second body 2 both have at least one plane, that is, at least the first surface 12 and the second surface 22 both need to be planes, so that the flexible display screen 5 can be installed on the planes, and the first body 1 and the second body 2 can be fastened after being rotated. The first body 1 and the second body 2 may be bodies that contain main parts of the electronic device, such as a main board, a processor, a display card, a memory, etc., and may further be provided with various sensors as needed, so that after the flexible display screen 5 is connected with the first body 1 and the second body 2, a device with complete functions may be formed.
The first side 11 of the first body 1 may be any one side of the first body 1, the first elliptic gear 3 disposed on the first side 11 may be set with appropriate parameters such as tooth number, module, pitch, etc. according to the use requirement, the second side 21 of the second body 2 may be any one side of the second body 2, and the parameters of the second elliptic gear 4 may be the same as those of the first elliptic gear 3, so that the two can be engaged. The first elliptic gear 3 can be directly arranged on the first side 11 of the first body 1 by welding, bolting or integral molding, or the first elliptic gear 3 can be connected with the first side 11 of the first body 1 by a connecting component, and the connection mode between the second elliptic gear 4 and the second side 21 of the second body 2 is the same as that between the first body 1 and the first elliptic gear 3.
The flexible display screen 5 can be a Liquid Crystal Display (LCD), a light emitting diode display (LED) or an organic light emitting diode display (OLED), as long as the flexible bending display screen can be realized. The connection between the flexible display screen 5 and the first surface 12 of the first body 1 and the second surface 22 of the second body 2 may be through adhesive connection, or may be fixed on the first surface 12 of the first body 1 and the second surface 22 of the second body 2 through a fixing frame, and the flexible display screen 5 further needs to be connected with a control device inside the first body 1 and the second body 2, for example, through a wire.
The flexible display screen 5 is connected to the first surface 12 of the first body 1 and the second surface 22 of the second body 2, respectively, the flexible display screen 5 may include three portions, a first portion of which is located on the first surface 12 of the first body 1, a second portion of which is located on the second surface 22 of the second body 2, and a third portion of which is located between the first body 1 and the second body 2, the third portion being a bending region 51 when the first body 1 rotates relative to the second body 2, the third portion being a drop-shaped bending shape when the first body 1 and the second body 2 rotate relative to each other and are fastened, and when the first body 1 and the second body 2 rotate relative to each other and are in a parallel state between the first surface 12 and the second surface 22, the third portion is in a flat state, and at this time, the flexible display screen 5 is in a flat unfolded state.
The electronic device provided by the embodiment of the invention is arranged in a manner that two machine bodies are meshed and rotated through the first elliptic gear 3 and the second elliptic gear 4, and the flexible display screen 5 is arranged on the surface capable of being buckled relatively between the two machine bodies, so that the bending state and the unfolding state of the flexible display screen 5 are realized. Wherein, because the elliptic gears have a long axis and a short axis with different lengths, when the two elliptic gears are meshed with each other and rotate, the change from the meshing of the positions of the short axis and the short axis to the meshing of the positions of the long axis and the long axis is generated, namely, the distance between the center of the first elliptic gear 3 and the center of the second elliptic gear 4 is changed and can be changed from small to large, so that the rotating structure between the first machine body 1 and the second machine body 2 is set into a structure in which the two elliptic gears are meshed and rotated, when the first machine body 1 rotates and unfolds the flexible display screen 5 relative to the second machine body 2, the distance between the center of the first elliptic gear 3 and the center of the second elliptic gear 4 is gradually increased, the distance between the first side edge 11 of the first machine body 1 and the second side edge 21 of the second machine body 2 is gradually increased, and then only when the first machine body 1 and the second machine body 2 rotate until the flexible display, the distance between the first side 11 of the first body 1 and the second side 21 of the second body 2 is the largest, so that the flexible display screen 5 is prevented from being pulled in the unfolding process, and the flexible display screen 5 is protected from being damaged in the unfolding process.
As shown in fig. 2 to 4, in an implementation, a major axis of the first elliptic gear 3 is parallel to the first surface 12 of the first body 1, and a major axis of the second elliptic gear 4 is parallel to the second surface 22 of the second body 2.
Specifically, the limit position of the relative rotation between the first body 1 and the second body 2 may be set at a position where the first surface 12 of the first body 1 is parallel to the second surface 22 of the second body 2, so that when the first body 2 rotates to the limit position, the flexible display screen 5 is in the unfolded state, or the major axis of the first elliptic gear 3 may be correspondingly parallel to the first surface 12 of the first body 1, and the major axis of the second elliptic gear 4 may be correspondingly parallel to the second surface 22 of the second body 2, so that when the first body 1 rotates to be parallel to the second body 2, the position corresponding to the major axis of the first elliptic gear 3 is engaged with the position corresponding to the major axis of the second elliptic gear 4, and at this time, the center of the first elliptic gear 3 is farthest from the center of the second elliptic gear 4, that is, when the first body 1 rotates relative to the second body 2, the distance between the center of the first elliptic gear 3 and the center of the second elliptic gear 4 is gradually increased, so that the flexible display screen 5 can be unfolded, and the flexible display screen 5 is prevented from being pulled in the unfolding process.
As shown in fig. 3, in an implementation, a portion of the flexible display 5 located between the first side 11 of the first body 1 and the second side 21 of the second body 2 is a bending area 51, that is, a third portion of the flexible display 5; when the flexible display screen 5 is in the unfolded state, the direction of the first side edge 11 of the first machine body 1 to the second side edge 21 of the second machine body 2 is the first direction, and the structural size and the setting mode of the first elliptic gear 3 and the second elliptic gear 4 are the same. The length S of the bending region 51 in the first direction is equal to the length of the long axis of the first elliptic gear 3, and the sum of the center of the first elliptic gear 3 and twice the distance between the first side 11 of the first body 1 in the first direction; or, the length S of the bending region 51 in the first direction is equal to the length of the long axis of the second elliptic gear 4, and the sum of the length S of the second bending region and the double distance between the center of the second elliptic gear 4 and the second side 21 of the second body 2 in the first direction.
When the flexible display screen 5 is in the unfolded state, the distance from the first side 11 of the first body 1 to the second side 21 of the second body 2 in the first direction, that is, the length of the bending area 51 in the first direction, may be set according to the needs of the user.
As shown in fig. 2 to 3, in a specific implementation, when the flexible display 5 is in a bent state, a direction from the first surface 12 of the first body 1 to the second surface 22 of the second body 2 is a second direction, and the first elliptic gear 3 and the second elliptic gear 4 have the same structural size and arrangement manner. Wherein the distance H between the first surface 12 of the first body 1 and the second surface 22 of the second body 2 is equal to the sum of the length of the minor axis of the first elliptic gear 3 and twice the distance between the center of the first elliptic gear 3 and the first surface 12 of the first body 1 in the second direction; or, the distance H between the first surface 12 of the first body 1 and the second surface 22 of the second body 2 is equal to the sum of the length of the minor axis of the second elliptic gear 4 and twice the distance between the center of the second elliptic gear 4 and the second surface 22 of the second body 2 in the second direction.
The distance between the first surface 12 of the first body 1 and the second surface 22 of the second body 2 may be set to limit the distance between the two surfaces that are engaged when the flexible display screen 5 is folded, and the distance may be specifically set according to the user's needs, and may be set by adjusting the lengths of the short axis of the first elliptic gear 3 and the short axis of the second elliptic gear 4.

Specifically, the sliding fit structure between the connecting member 6 and the first sliding chute 31 and the second sliding chute 41 is used for maintaining the meshing state of the first elliptic gear 3 and the second elliptic gear 4, and is also used for limiting the relative rotation limit position of the first elliptic gear 3 and the second elliptic gear 4. Therefore, the first slide slot 31 and the second slide slot 41 are both arranged along the arc shape, so that after the connecting piece 6 is connected with the two slide slots in a sliding manner, the connecting piece 6 can slide in the first slide slot 31 and the second slide slot 41 relatively when the first elliptic gear 3 and the second elliptic gear 4 rotate in a relative meshing manner.

Specifically, all set up first spout 31 and second spout 41 to the T-slot to the complex sets up the spliced pole 62 of connecting piece 6 to the ladder column, then after connecting piece 6 and two spout cooperations, can avoid connecting piece 6 and two spouts to break away from.
