Description

Supporting structure and display device

Technical Field

The invention relates to the technical field of display equipment, in particular to a supporting structural member and a display device.

Background

With the development of flexible display technology, flexible screens are increasingly applied to terminal devices. In a terminal device, a flexible screen and a flexible screen support structure are combined, and the flexible screen is bent or folded by using the flexible screen support structure. Compared with the traditional screen, the flexible screen has the advantages of being light and thin in size and low in power consumption, and due to the fact that the flexible screen is bendable and has the characteristics of flexibility and the like, the application range of the flexible screen is wider and wider. However, when the flexible display screen is unfolded, the supporting structure of the flexible display screen in the prior art cannot provide a flat plane to support the flexible display screen on the whole surface, which affects touch feeling, has poor stability and is easy to damage the screen body.

Therefore, a new supporting structure and a display device are needed.

Referring to fig. 1 to fig. 3, fig. 1 is a schematic structural diagram of a display device according to an embodiment of the present invention; FIG. 2 is an isometric view of a display device provided by an embodiment of the invention; fig. 3 is an exploded schematic view of a display device according to an embodiment of the present invention.

An embodiment according to a first aspect of the present invention provides a display device including a display panel 100 and a support structure 200, the support structure 200 being configured to provide support to the display panel 100. The display device has a first side AA1 and a second side AA2 oppositely disposed in a thickness direction thereof (Z direction in fig. 2), or the display device has a first side AA1 oppositely disposed in a thickness direction thereof.

In some alternative embodiments, the display panel 100 is a flexible display panel 100, and the display panel 100 is deformable. The support structure 200 is telescopically arranged, and the display panel 100 and the support structure 200 are slidably connected, at least a portion of the display panel 100 is positioned at the second side AA2 around the support structure 200. When the support structure 200 is extended, the display panel 100 of the second side AA2 can move to the first side AA1, thereby increasing the display area of the display device.

The display device in the embodiment of the present invention includes, but is not limited to, a mobile phone, a Personal Digital Assistant (PDA), a tablet computer, an electronic book, a television, a door lock, a smart phone, a console, and other devices having a display function.

Referring to fig. 4, fig. 4 is a schematic structural diagram of a supporting structural member 200 according to a second embodiment of the present invention. The support structure 200 may be the support structure 200 of the display device of the first embodiment described above.

The support structure 200 according to the embodiment of the second aspect of the present invention is used to support the display panel 100, and the support structure 200 includes: the first support 200 a; a second support 200b movably connected to the first support 200a along a first direction (X direction in fig. 2), the second support 200b having a support beam 230 disposed thereon; the supporting beam 230 is disposed on a side of the second supporting member 200b close to the display panel 100, and when the second supporting member 200b is far away from the first supporting member 200a along the first direction, at least a portion of the supporting beam 230 can extend out of the first supporting member 200a to support the display panel 100. In the support structure 200 of the embodiment of the present invention, the support structure 200 includes a first support 200a and a second support 200 b. The second support member 200b is provided with a support beam 230. The second support 200b is movably connected to the first support 200a, and when the second support 200b is far away from the first support 200a, at least a portion of the supporting beam 230 can extend out of the first support 200a, such that the supporting beam 230 extending out of the first support 200a can support the display panel 100. Therefore, in the embodiment of the present invention, when the second support member 200b moves away from the first support member 200a, the supporting beam 230 can extend out of the first support member 200a to provide support for the display panel 100, and the supporting structure member 200 of the embodiment of the present invention can provide stable support for the display panel 100, thereby improving the stability of the display panel 100 in use.

Optionally, the number of the supporting beams 230 is one.

In other embodiments, the number of the supporting beams 230 is multiple, and the supporting beams 230 are arranged side by side along the first direction. When the second support member 200b moves away from the first support member 200a, the one or more support beams 230 can extend out of the first support member 200a, so that the displacement dimension of the support structure member 200 in the first direction can be reasonably controlled. When the support structure 200 is used for a display device, the display device can display in multiple sizes, and various requirements of users can be met.

The first and

second supports

200a and 200b are provided in various manners, and the second support 200b includes a second support plate 220 for supporting the support beam 230, and the second support plate 220 has a mounting surface for mounting the support beam 230. The relative position of the second support plate 220 and the first support 200a in the thickness direction of the support structure 200 is adjustable, so that the second support plate 220 can drive the support beam 230 to displace in the thickness direction of the support structure 200, so as to move the support beam 230 into the first support 200a or extend out of the first support 200 a.

Optionally, the first support 200a includes a first support plate 210 for supporting the display panel 100, and the first support plate 210 has a bearing surface 211 for supporting the display panel 100. The relative positions of the second supporting plate 220 and the first supporting plate 210 in the thickness direction of the supporting structure 200 are adjustable, so that when the second supporting member 200b is close to the first supporting member 200a along the first direction, the second supporting plate 220 can drive the supporting beam 230 to move to the side of the first supporting plate 210 far away from the display panel 100.

The support beam 230 has a preset length in the second direction (Y direction in fig. 2), for example. The second direction intersects the first direction. The angle between the second direction and the first direction can be set in various ways, for example, the second direction is perpendicular to the first direction, and the angle between the second direction and the first direction is 90 degrees.

The extension of the supporting beam 230 in the second direction is less than or equal to the extension of the first support plate 210 in the second direction so that the supporting beam 230 can be completely covered by the first support plate 210. Optionally, the extension of the supporting beam 230 in the second direction is close to the extension of the first support plate 210 in the first direction, for example, the absolute value of the difference between the extension of the supporting beam 230 in the second direction and the extension of the first support plate 210 in the first direction is less than or equal to 10 mm. So that the support beam 230 can provide better support to the display panel 100.

Optionally, the support structure 200 has a collapsed state and an expanded state.

With continued reference to fig. 1 and 2, fig. 1 and 2 are schematic structural views of the support structure 200 in a collapsed state. In the contracted state, at least a portion of the second supporting plate 220 and the supporting beam 230 are located on a side of the first supporting plate 210 facing away from the bearing surface 211.

With continued reference to fig. 4, fig. 4 is a schematic view of the support structure 200 in an unfolded state. The second support plate 220 protrudes from the first support plate 210 in the first direction such that the support structure 200 is transformed into the unfolded state. In the unfolded state, at least a portion of the support beam 230 extends beyond the first support plate 210 and is juxtaposed with the first support plate 210. In the first direction, the support structure 200 has an extension in the collapsed state that is smaller than its extension in the expanded state. That is, when the support structure 200 is transformed from the contracted state to the expanded state, the size of the support structure 200 in the first direction may increase.

In these alternative embodiments, the support structure 200 can be transitioned between the collapsed state and the expanded state by moving the second support plate 220, thereby changing the extension of the support structure 200 in the first direction. When the support structure 200 is used to support the display panel 100, the support structure 200 in the unfolded state can increase the size of the display panel 100 located at the first side AA1, thereby implementing a large screen display of the display device. The support structure 200 is in a contracted state to facilitate storage of the display device.

Referring to fig. 5, fig. 5 is a partial enlarged structural diagram of fig. 4.

In some alternative embodiments, the supporting beam 230 is connected to the second supporting plate 220 through the second returning part 231, and the second returning part 231 is reciprocally deformable in the thickness direction. When the second supporting plate 220 moves relative to the first supporting plate 210 and at least a portion of the supporting beam 230 moves out of the first supporting plate 210, the supporting beam 230 can move in the thickness direction when the second restoring portion 231 is elastically deformed.

The first support plate 210 can provide resistance to the extending support beams 230, achieve free stop of one or more support beams 230, and can maintain the support structure 200 at a suitable size.

Alternatively, in the contracted state, the supporting beam 230 is positioned at a side of the first supporting plate 210 away from the display panel, and the second restoring portion 231 is compressed. When the second supporting plate 220 moves in the first direction to transform the supporting structure 200 from the contracted state to the expanded state, and the second supporting plate 220 drives at least a portion of the supporting beam 230 to extend out of the first supporting plate 210, the supporting beam 230 extending out of the first supporting plate 210 receives no pressure. The second restoring part 231 connected to the supporting beam 230 protruding from the first support plate 210 is restored and unfolded in the thickness direction so that the supporting beam 230 protruding from the first support plate 210 moves in the thickness direction and so that the supporting beam 230 protruding from the first support plate 210 is flush with the first support plate 210 in the first direction and provides a supporting force to the display panel 100 together.

In other embodiments, in the contracted state, the supporting beam 230 is positioned at a side of the first supporting plate 210 away from the display panel, and the second restoring portion 231 is compressed. When the second supporting plate 220 moves in the first direction to transform the supporting structure 200 from the contracted state to the expanded state, and the second supporting plate 220 drives at least a portion of the supporting beam 230 to extend out of the first supporting plate 210, the supporting beam 230 extending out of the first supporting plate 210 receives no pressure. The second restoring part 231 coupled with the supporting beam 230 extending from the first support plate 210 is restored and spread in the thickness direction so that the supporting beam 230 extending from the first support plate 210 moves in the thickness direction, but the distance that the supporting beam 230 moves in the thickness direction is limited, and the supporting beam 230 extending from the first support plate 210 cannot be flush with the first support plate 210 in the first direction. At this time, the second support plate 220 is moved close to the first support plate 210 in the thickness direction, so as to drive the support beams 230 extending out of the first support plate 210 to continue to move in the thickness direction and make the support beams 230 extending out of the first support plate 210 and the first support plate 210 level in the first direction, so that at least part of the support beams 230 and the first support plate 210 can provide a support force for the display panel 100 together.

In still other embodiments, in the contracted state, the supporting beam 230 is located at a side of the first supporting plate 210 away from the display panel, and the second restoring portion 231 is in a natural state. When the second supporting plate 220 moves in the first direction to transform the supporting structure 200 from the retracted state to the extended state, and the second supporting plate 220 drives at least a portion of the supporting beam 230 to extend out of the first supporting plate 210, the state of the second restoring portion 231 is not changed, and the supporting beam 230 does not move in the thickness direction. At this time, the second supporting plate 220 is moved close to the first supporting plate 210 along the thickness direction, so as to drive the supporting beams 230 extending out of the first supporting plate 210 to continue to move along the thickness direction and make the supporting beams 230 extending out of the first supporting plate 210 and the first supporting plate 210 level along the first direction, so that at least part of the supporting beams 230 and the first supporting plate 210 can provide a supporting force for the display panel 100 together. At this time, the supporting beam 230 located on the side of the first supporting plate 210 facing away from the display panel receives the pressure of the first supporting plate 210, and the second restoring member 231 is transformed from the natural state to the contracted state.

For example, two second reset portions 231 are disposed on the same supporting beam 230, and the two second reset portions 231 are spaced apart along the second direction, so as to provide more stable support to the supporting beam 230 through the two second reset portions 231.

The second restoring portion 231 may be disposed in various manners, for example, the second restoring portion 231 includes a second guide rod 231a and a second elastic member 231b reciprocally deformable along the second guide rod 231a, and the second guide rod 231a is movably disposed in the thickness direction with respect to the second support plate 220. For example, the second support plate 220 is provided with a mounting hole, the second guide rod 231a is formed to extend in the thickness direction, one end of the second guide rod 231a is connected to the support beam 230, and the other end is movably disposed in the mounting hole. Optionally, a stop 231c is further disposed at an end of the second guide rod 231a away from the supporting beam 230, and the stop 231c is located at a side of the second supporting plate 220 away from the supporting beam 230, so as to prevent the second guide rod 231a from falling off from the mounting hole of the second supporting plate 220.

The supporting beam 230 can be disposed in various ways, and in some embodiments, the supporting beam 230 includes a pressing portion 232 and a stopping portion 233. In the first direction, the pressing portion 232 and the stopping portion 233 are respectively disposed at both sides of the supporting beam 230; wherein, in a direction away from the first support plate 210, the stopper portion 233 of the support beam 230 close to the first support 200a is pressed by the pressing portion 232 of the latter support beam 230. I.e. the latter support beam 230 can provide a stop for the former support beam 230, which can ensure that the support beam 230 that is moved out of the first support plate 210 is level in the first direction.

In these alternative embodiments, when the driving button 243 is pressed in a direction approaching the lifting portion 242 by the cooperation of the first inclined surface 242b and the second inclined surface 243a, the mutual pressing force of the first inclined surface 242b and the second inclined surface 243a generates a driving force in the thickness direction, thereby driving the lifting portion 242 to lift in the thickness direction.
