Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The first embodiment is as follows:

fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the invention. Fig. 2 is a schematic diagram of an alternative structure of an electronic device according to an embodiment of the present invention.

An embodiment of the present invention provides an electronic device, and as shown in fig. 1, the electronic device according to the embodiment of the present invention includes: the flexible screen comprises a body 3 (not shown in the figure), a flexible screen 1 and a first bending device 2, wherein the flexible screen 1 is arranged on the body 3.

The flexible screen 1 comprises at least a first end face 11. The first bending device 2 is disposed on the first end surface 11.

When the flexible screen 1 is stressed to bend, the flexible screen 1 drives the first bending device 2 to bend; the first bending center 12 of the flexible screen 1 coincides with the second bending center 21 of the first bending device 2 or differs by a preset distance value.

In the embodiment of the present invention, the flexible screen 1 may have a display surface, and the end surface of the flexible screen 1 is a side surface generally perpendicular to the display surface of the flexible screen 1. Alternatively, the first end surface 11 may be a corresponding side surface in the length direction of the display surface of the flexible screen 1.

In an embodiment of the present invention, referring to fig. 2, the flexible screen 1 may be bent centering on at least one first bending center 12. When the flexible screen 1 is in a bent state, the flexible screen 1 can be divided into a first part 13 and a second part 14 by taking the first bending center 12 as a center, and the bending of the flexible screen 1 is equivalent to that the first part 13 or the second part 14 rotates by taking the first bending center 12, that is, the first bending center 12 is a rotation center when a part of the screen is bent when the flexible screen 1 is in the bent state.

For example, when the first end surface 11 of the flexible screen 1 is perpendicular to the display surface of the flexible screen 1 which is not in the bent state, the first bending center 12 may intersect with a central bisector of the first end surface 11 in the length direction at a point on the first end surface 11.

In an embodiment of the present invention, the first bending device 2 may be bent with at least one second bending center 21 as a center. The second bending center 21 of the first bending device 2 may be a rotation center of the first bending device 2 when the partial bending device bends in the bending state.

Optionally, the flexible screen 1 may have a plurality of first bending centers 12, the first bending device 2 may have a plurality of second bending centers 21, and the plurality of first bending centers 12 and the plurality of second bending centers 21 may correspond to each other one by one.

In the embodiment of the present invention, optionally, the first bending device 2 may be disposed on the first end surface 11 of the flexible screen 1 in various ways.

In an alternative arrangement, as shown in fig. 2, the first bending device 2 may include a limiting connection 22 having a second bending center 21, the limiting connection 22 may have a first folding portion 201 and a second folding portion 202, the first folding portion 201 and the second folding portion 202 may rotate around the second bending center 21, the distance between the first folding portion 201 and the second folding portion 202 and the second bending center 21 is constant, and the first folding portion 201 and the second folding portion 203 may be connected to the first portion 13 and the second portion 14 of the flexible screen 1 divided by the first bending center, respectively. Alternatively, the first and

second folds

201, 202 may be made of a rigid material. The first bending device 2 may further include a connecting shaft 203, one end of the connecting shaft 203 and the flexible screen 1 are connected to an intersection point of the first bending center 12 and the first end face 11, the other end of the connecting shaft 203 is connected to the limiting connecting member 22, and an axis of the connecting shaft may coincide with the second bending center or differ from the second bending center by a preset distance value.

It should be noted that fig. 1 shows a connection setting schematic diagram of the flexible screen and the first bending device 2 when the first bending center 12 coincides with the second bending center 21, and with this setting, when the flexible screen 1 bends with the first bending center 12, the first bending device 2 is driven to bend with the second bending center 21, and the first bending center 12 coincides with the second bending center 21, and it is seen that the first bending device 2 can limit the bending direction of the flexible screen 1 to the first bending center 12. Meanwhile, when the flexible screen 1 is subjected to an external force in a first direction, the stressed first part 13 of the flexible screen 1 can be bent in the first direction by taking the first bending center 12 as a center, and when the flexible screen 1 is subjected to an external force opposite to the first direction, the flexible screen can be bent in a second direction by taking the first bending center 12 as a center, namely, the stressed part of the screen can rotate bidirectionally by taking the first bending center 12 as a center. By adopting the mode that the first bending center 12 and the second bending center 21 are overlapped, the two directions of partial screen of the flexible screen 1 can support 360-degree rotation.

Similarly, the first bending center 12 and the second bending center 21 may be disposed parallel to each other, and a distance between the first bending center 12 and the second bending center 21 is smaller than a predetermined distance value. With this arrangement, the first bending device 2 can define the first bending center 12 of the flexible screen 1 as a range. Meanwhile, the flexible screen 1 can be ensured to support bidirectional bending. By adopting the way that the distance between the first bending center 12 and the second bending center 21 is smaller than the preset distance value, the bending radius of the first bending center 12 of the flexible screen can be smaller, so that the user can bend the flexible screen more easily.

On this basis, because the bending center of the flexible screen 1 is limited, the electronic equipment bearing the flexible screen can be bent according to a certain bending center or a certain group of bending centers, and therefore the wearable function of the electronic equipment is optimized.

For example, the electronic device in the embodiment of the present invention may be a watch, the flexible screen 1 may be disposed to cover a part or the whole of a hand circumference when worn, the flexible screen 1 may have a plurality of first bending centers 12, the first bending device 2 may have a plurality of second bending centers 21, each first bending center 12 corresponds to each second bending center 12 one-to-one, the first end face 11 may be an end face perpendicular to the arm direction, the first bending device 2 being arranged on the first end face 11, so that the first bending direction 12 is parallel to the arm extension direction when the watch is arranged, therefore, the flexible screen 1 can be bent around the wrist to be beneficial to wearing, meanwhile, parts which are not allowed to be bent, such as a main board and a battery, can be arranged in the region where the back face or the side face of the flexible screen 1 can not be folded, and the parts can be arranged on the wrist watch close to the flat part of the arm. In addition, because flexible screen 1 can two-way buckling for the user can buckle forward or backward when taking off the wrist-watch, conveniently form the form that can stand upright in the desktop in the wrist-watch, convenience of customers looks over, and the user can fully enjoy the abundant enjoyment that wearable electronic equipment brought at the in-process that freely sets up the upright form of electronic equipment.

According to the embodiment of the invention, the flexible screen is used as the display screen of the electronic equipment, the first bending device is arranged on the first end surface of the flexible screen, and the first bending device is driven to bend when the flexible screen is bent under stress, wherein the first bending center of the flexible screen is overlapped with or differs from the second bending center of the first bending device by a preset distance value, namely the first bending center of the flexible screen can be accurately or approximately determined according to the second bending center of the first bending device, so that the first bending center of the flexible screen can be arranged by arranging the second bending center of the first bending device, and the electronic equipment can be bent in the using process.

FIG. 6 is a diagram illustrating various bending configurations of an electronic device according to an embodiment of the invention. FIG. 7 is a side view of an electronic device according to an embodiment of the invention in various folded configurations. As shown in fig. 6 and 7, in various bending forms, the electronic device can support bidirectional bending and maintain a bending state through the limiting effect of the first bending device 2, and the curved surface of the flexible screen 1 is parallel to the straight line perpendicular to the display surface of the flexible screen in any bending state, so that a non-bending device can be conveniently arranged.

In the embodiment of the present invention, when the axial center of a certain first connecting shaft 231 is collinear with the axial center of the corresponding bending shaft 221, the first bending center 12 corresponding to the first connecting shaft 231 coincides with the second bending center 12 corresponding to the bending shaft 221.

When the cross section of the stopper groove 2210 is larger than the cross section of the first connecting shaft 231 in the direction perpendicular to the axial center of the bending shaft 221, it is possible to allow the distance between the first bending center 12 and the second bending center 21 to vary within a range that can be any value from the coincidence to a preset distance value. Since the flexible screen 2 itself is usually very thin, but the bending axis 221 cannot be made very thin, the bending radius of the flexible screen 2 is limited by the distance between the bending axis 221 and the adjacent bending axis 221, in this way, the influence of the distance between the adjacent bending axes 221 on the bending radius of the flexible screen 2 can be reduced, so that the bending radius of the flexible screen 2 is smaller and the bending operation is easier.
