It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

In some embodiments, the shaft is comprised of two hinges. When being applied to among the electronic equipment, the pivot setting is in flexible display screen lid below, and the hinge in the pivot links to each other with the back of flexible display screen.

By adopting the mode, the two hinges are easy to excessively bend when being bent, so that the relative rotation angle is large, and the hinges obviously stretch the flexible screen at the moment. Therefore, when the flexible display screen is restored to the flat state, the flexible display screen is prone to local bulge, and the service life of the electronic equipment and the user experience are affected.

Based on the above situation, the embodiment of the present disclosure provides a rotating shaft, which can effectively support a flexible display screen, and avoid overstretching the flexible display screen in a bending state, thereby solving the defect that the flexible display screen bulges after being bent. Fig. 1 to 7 are schematic views illustrating a structure of a rotation shaft according to various exemplary embodiments.

As shown in fig. 1, the rotating shaft provided by the embodiment of the present disclosure includes: a hinged hinge 100, and an elastic member 200.

Fig. 2 shows a schematic structural view of a hinge 100, and as shown in fig. 2, the hinge 100 includes a hinge body 110, a first connecting portion 120, and a second connecting portion 130.

In one embodiment, the hinge body 110 has a support surface 111, a first side surface 112, a bottom surface 113, and a second side surface 114, which are connected in series. The support surface 111 is disposed opposite the bottom surface 113, and the first side surface 112 and the second side surface 114 are disposed opposite each other. Wherein the support surface 111 is used to support external components, such as a flexible display screen.

Alternatively, the supporting surface 111, the first side surface 112, the bottom surface 113, and the second side surface 114 are flat surfaces, for example, the hinge body 110 has a cubic structure.

Alternatively, at least one of the supporting surface 111, the first side surface 112, the bottom surface 113, and the second side surface 114 is formed by splicing a plurality of surfaces. For example, the first side surface 112 includes a flat surface and a curved surface, and the edge of the curved surface away from the flat surface is connected with the supporting surface 111 (i.e., the edge where the supporting surface 111 and the first side surface 112 are connected is rounded).

The first connection portion 120 is disposed on the first side surface 112, and the second connection portion 130 is disposed on the second side surface 114. Referring to fig. 1, in the two hinges 100 connected, the first connection portion 120 of one hinge 100 is hinged to the second connection portion 130 of the other hinge 100.

As an example, the plurality of hinges 100 are connected by a rotation shaft 300. In this case, the first connecting portion 120 is provided with a first pin hole 121, and the second connecting portion 130 is provided with a second pin hole 131 parallel to the axis of the first pin hole 121. The pin 300 simultaneously passes through the first pin hole 121 of one hinge 100 and the second pin hole 131 of the other hinge to realize hinging, and the two hinges 100 can rotate relative to each other by taking the pin 300 as an axis.

Further, the position of the first pin-shaft hole 121 satisfies: in the flat state, in the two hinges 100 that are hinged, the first connection portion 120 of one hinge 100 has a gap to the hinge main body 110 of the other hinge 100. The position of the second pin 131 satisfies: in the flat state, in the two hinges 100 that are hinged, the second connecting portion 130 of one hinge 100 has a gap to the hinge main body 110 of the other hinge 100.

In this way, the two hinges 100 that are hinged can rotate relative to each other without contacting each other. Under the condition, the bending resistance of the rotating shaft is reduced, and the rotating shaft is ensured to be bent smoothly. It should be noted that the larger the gap, the larger the rotation angle that can be realized by the two hinges 100 without contacting each other, and the larger the angle at which the rotation shaft is not blocked and bent. When the pin shaft is used, the size of the gap can be determined according to the bending requirement of the rotating shaft, and the arrangement positions of the first pin shaft hole 121 and the second pin shaft hole 131 can be regulated and controlled.

Further, a first inclined surface 122 is provided on a side of the first connection portion 120 away from the hinge main body 110. A second inclined surface 132 is provided at a side of the second connection portion 130 away from the hinge main body 110. The first ramp 122 and the second ramp 132 are both adjacent to a side of the hinge 100 for connection to an external component. The first inclined surface 122 and the second inclined surface 132 provide more rotating space for the connected hinge 100, and the rotating shaft can achieve the desired bending degree.

The hinge 100 is further provided with an insertion hole 140 penetrating in a direction from the first connection portion 120 to the second connection portion 130. The insertion holes 140 are used to install the elastic members 200, and particularly, the elastic members 200 are disposed through the insertion holes 140 of at least three hinge joints 100. Also, the insertion hole 140 is located on the same side of the first and second pin-

shaft holes

121 and 132. In this way, the insertion hole 140, the first pin hole 121, and the second pin hole 132 are independent and not communicated with each other, so that the elastic element 200 is not in contact with the pin 300, and the structural loss caused by the mutual friction between the two is avoided.

In addition, the number of hinges 100 in the rotating shaft is not limited in the disclosed embodiment, such as 2, 3, 4, 5, 6, etc. When the hinge includes more than 2 hinges, it is preferable that the elastic member 200 penetrates the insertion holes 140 of all the hinges 100.

When the rotating shaft provided by the embodiment of the present disclosure is bent, the adjacent hinges 100 rotate relatively to each other to form a state as shown in fig. 1. The elastic member 200 in the hinge shaft penetrates the insertion hole 140 of the hinge 100 to support the hinge 100. In such a way, excessive rotation between the connected hinges 100 is avoided, so that the acting force of the rotating shaft on the external component is distributed more uniformly, and the structure stability of the external component is ensured.

And, when the rotation axis includes more than 2 hinges 100, the supporting surfaces 111 of the plurality of hinges 100 form a curved distribution. The external components can be better supported by the support surfaces 111 of the plurality of hinges 100. In the case that the rotating shafts are bent to the same degree, compared with the case that only two hinges are adopted to form the rotating shaft, the rotating shaft provided by the embodiment of the present disclosure has a larger angle formed by adjacent hinges 100, and the plurality of hinges 100 are gradually transited.

Therefore, the rotating shaft provided by the embodiment of the disclosure can be better attached to the external component, and the external component is prevented from being structurally damaged due to excessive stretching of the external component. Especially, when the rotating shaft is matched with the flexible display screen, the hinge 100 in the rotating shaft can support the flexible display screen by more uniform stress in the rotating process of the flexible display screen, so that the local stress is prevented from being protruded. Therefore, when the flexible display screen is returned to the flat state from the bending state, local hollowing cannot occur, and the service life and the user experience of the display screen are optimized.

In one embodiment, the first and second connecting

portions

120 and 130 are staggered along the relative axes of rotation of the two hinges 100. In this way, as shown in fig. 3, the end faces of the plurality of hinges 100 (the upper and lower end faces of the hinges 100 in fig. 3) are almost in the same plane in the connecting direction of the plurality of hinges 100. Under the condition, the rotating shaft is in an equal-width state, and the external components are supported more uniformly and stably.

In the disclosed embodiment, the first connection portion 120 and the second connection portion 130 have various implementations, which are described in detail below with reference to the accompanying drawings.

As a first example, as shown in fig. 3, the first connection portion 120 and the second connection portion 130 are each a single structure. The first and second connecting

portions

120 and 130 are located at opposite ends of the hinge body 110, respectively, in a direction along the pin-shaft hole of the hinge body 110.

As a second example, as shown in fig. 4, the first connection portion 120 and the second connection portion 130 are each a separate structure. Specifically, the first connection part 120 includes a first connection member 123 and a second connection member 124; the second connection portion 130 includes a third connection member 133 and a fourth connection portion 134. The first link 123, the second link 124, the third link 133, and the fourth link 134 are staggered in a direction along the pin hole of the hinge body 110 (e.g., the third link 133, and the fourth link 134 are located between the first link 123 and the second link 124).

As a third example, as shown in fig. 5, the first connection part 120 is a separate structure (including the first connection member 123 and the second connection member 124), and the second connection part 130 is a single structure. And the second connecting part 130 is disposed between the first connecting part 123 and the second connecting part 124 in a direction along the pin hole of the hinge main body 110.

Based on the above-mentioned implementation of the first connection portion 120 and the second connection portion 130, the insertion hole 140 in the hinge 100 also has various implementations, which will be described below with reference to the specific drawings.

As a first example, as shown in fig. 6-1 and 6-2, the insertion hole 140 forms a first opening 141 and a second opening 142 that are oppositely disposed on the hinge body 110. Specifically, the receptacle 140 forms a first opening 141 on the first side 112 and a second opening 142 on the second side 114.

In such a case, the first and

second connection portions

120, 130 are each of a unitary construction, for example, in the manner and orientation shown in fig. 6-1. The first connection portion 120 is disposed at the left side of the first opening 141, and the second connection portion 130 is disposed at the right side of the second opening 142.

Alternatively, for example, in the manner and orientation shown in fig. 6-2, the first connection portion 120 and the second connection portion 130 are both separate structures. The first connection portion 120 includes a first connection member 121 and a second connection member 122 respectively disposed at opposite sides of the first opening 141. The second connection portion 130 includes a third connection member 131 and a fourth connection member 132 respectively disposed at opposite sides of the second opening 142.

In the first example, the first connection portion 120 and the second connection portion 130 avoid the opening of the insertion hole 140 on the hinge 100, and ensure that the elastic member 200 smoothly penetrates through the hinge 100 through the insertion hole 140.

As a second example, as shown in fig. 7 in conjunction with fig. 2, the insertion hole 140 forms a first opening 141 on the hinge body 110 and a second opening 142 on the second connection portion 130, the first opening 141 being disposed opposite to the second opening 142.

As a preferred way of this example, the receptacle 140 forms a first opening 141 on the first side 112. The first connection portion 120 includes a first connection member 123 and a second connection member 124 respectively disposed at opposite sides of the first opening 141. The second connecting portion 130 protrudes from the second side surface 114, and the second connecting portion 130 is located between the first connecting member 123 and the second connecting member 124 along the pin shaft hole direction of the hinge 100. The insertion hole 140 penetrates the second connection portion 130, and a second opening 142 is formed on a surface of the second connection portion 130 away from the second side surface 114.

In this way, the length of the insertion hole 140 is extended by penetrating the second connection portion 130, so that the support stability of the hinge 100 by the elastic member 200 is enhanced. And, the hinge stability of the two hinges 100 is optimized by simultaneously connecting the first connection member 123 and the second connection member 124 to one second connection portion 130.

Further, in one embodiment, the elastic member 200 includes a sheet-like structure, such as an elastic band or sheet, etc. The elastic member 200 of the sheet structure provides stronger supporting force for the hinge 100, and effectively prevents the hinge 100 from being bent excessively. In this way, the hinge 100 cannot rotate about the elastic member 200, and the structural stability of the entire rotating shaft is improved.

Also, in the disclosed embodiment, the hinge 100 is a rubber hinge. Accordingly, the hinge 100 is flexible and elastic, and is more suitable for being attached to an external component, and the external component is optimally supported.

A second aspect of the present disclosure provides an electronic device, which includes a flexible display screen, and the hinge provided in the first aspect. The flexible display screen includes a display surface for displaying, and a back surface opposite the display surface. The rotating shaft is arranged inside the electronic equipment and connected with the back of the flexible display screen. Specifically, the supporting surface 11 of the hinge 100 in the rotating shaft is connected to the back surface of the flexible display, and both ends of the elastic member 200 in the rotating shaft are fixed inside the electronic device.

When the flexible display screen is bent, the rotating shaft is bent along with the flexible display screen, so that the support surface 11 can well support the bent part of the flexible display screen. Moreover, because the rotating shaft comprises at least three hinges 100, the hinges 100 are gently transited into a bent shape in the bending process, the tensile force of the hinges 100 to the flexible display screen is uniformly distributed, and obvious stress concentration cannot occur. Therefore, when the flexible display screen is restored to the flat state, the display screen can be kept flat, and the situation that bulges and bulges are generated at the bent position is avoided. In this way the lifetime and user experience of the flexible display is optimized.

Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
