Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

Further, in the present application, directional terms such as "upper" and "lower" are defined with respect to a schematically-disposed orientation of components in the drawings, and it is to be understood that these directional terms are relative concepts that are used for descriptive and clarity purposes and that will vary accordingly with respect to the orientation in which the components are disposed in the drawings.

The embodiment of the application provides a folding display terminal, which can be a product with a display interface, such as a mobile phone, a display, a tablet computer, a vehicle-mounted computer and the like. The embodiment of the present application does not specially limit the specific form of the folding display terminal.

As shown in fig. 1, a flexible screen 10 included in a display terminal 01 is folded. The flexible screen 10 may be an Active Matrix Organic Light Emitting Diode (AMOLED) display screen.

The AMOLED display screen is a self-luminous display screen, and a Back Light Module (BLM) is not required. Therefore, when the substrate in the AMOLED display screen is made of a flexible resin material, such as polyethylene terephthalate (PET), the AMOLED display screen can have a bendable characteristic.

In addition, as shown in fig. 1, the folding display terminal 01 further includes a folding assembly 20 for carrying the flexible screen 10.

The folding assembly 20 includes a first housing 201, a second housing 202, and a hinge 203 between the first housing 201 and the second housing 202.

As shown in fig. 2a, the rotating shaft 203 is connected to the first casing 201 and the second casing 202. The first housing 201 and the second housing 202 are located on both sides of the rotating shaft 203, i.e. the first housing 201 is located on the left side of the axis O-O of the rotating shaft 203, and the second housing 202 is located on the right side of the axis O-O of the rotating shaft 203.

The first housing 201 and the second housing 202 are rotatable about the axis O-O of the rotary shaft 203, respectively.

In order to rotatably connect the first housing 201 and the second housing 202 through the shaft 203, the shaft 203 includes a shaft body 2031 as shown in fig. 2 b.

The shaft body 2031 includes a first rotating shaft 213 and a second rotating shaft 223 coaxially disposed. The axes of the first and second rotating shafts 213 and 223 serve as the axis O-O of the rotating shaft 203.

In addition, the folding assembly 20 includes a first blade 204 and a second blade 214 as shown in FIG. 2 b. One end of the first blade 204 is connected to the first rotating shaft 213 in the rotating shaft body 2031, and the other end thereof can extend into the groove 02 below the first housing 201 and is connected to the first housing 201 by a screw installed in the screw hole 224.

One end of the second blade 214 is connected to the second rotating shaft 223 of the shaft body 2031, and the other end thereof extends into a groove (not shown) below the second housing 202 and is connected to the second housing 202 by a screw installed in the screw hole 224.

As shown in fig. 2b, the first rotating shaft 213 drives the first casing 201 to rotate around the axis of the first rotating shaft 213 via the first blade 204. The second rotating shaft 223 drives the second housing 202 to rotate around the axis of the second rotating shaft 223 through the second blade 214.

The axes of the first rotating shaft 213 and the second rotating shaft 223 can be used as the axes of the rotating shaft 203 shown in fig. 2a, so that the first housing 201 and the second housing 202 can rotate along the axis O-O of the rotating shaft 203 respectively.

In addition, in some embodiments of the present application, the shaft 203 further includes a shaft housing 2032 as shown in fig. 2 c. The spindle body 2031 shown in fig. 2b is disposed inside the spindle housing 2032. A gap is formed between the shaft body 2031 and the shaft housing 2032. In this way, the spindle body 2031 can be rotated within the spindle housing 2032.

In this case, in order to connect the first blade 204 to the first housing 201, the first rotation shaft 213 positioned in the shaft housing 2032 is provided with a first mounting groove 2132 facing the first housing 201, as shown in fig. 2 c. The first blade 204 protrudes out of the first mounting groove 2132 and is connected to the first housing 201.

In addition, in order to couple the second blade 214 to the second housing 202 through the second rotation shaft 223 positioned in the shaft housing 2032, as shown in fig. 2c, a second mounting groove 2232 facing the second housing 202 is formed in the shaft housing 2032. The second blade 214 protrudes through the second mounting groove 2232 and is coupled to the second housing 202.

In this way, the shaft housing 2032 can protect the first and second rotating shafts 213 and 223 in the shaft body 2031 and prevent moisture, dust, and the like from affecting the rotation performance of the first and second rotating shafts 213 and 223.

On this basis, as shown in fig. 3a or fig. 3b, a part of the flexible screen 10 is fixed on the first casing 201 by a glue layer (black coating part in fig. 3 a), a part is fixed on the second casing 202 by a glue layer, and the rest of the flexible screen 10 is located between the first casing 201 and the second casing 202.

It should be noted that, in the present application, the glue layer for bonding the two components may be a film layer formed after the glue of the drawings.

The first housing 201 and the second housing 202 are used for carrying the flexible screen 10, so as to ensure the flatness of the flexible screen 10 and protect the non-display surface of the flexible screen 10. In addition, other electronic components, such as a camera, a headset, an earphone, a button, a battery, and the like, are disposed on the first housing 201 and the second housing 202.

The first housing 201 and the second housing 202 rotate along the axis O-O (as shown in fig. 2 a) of the rotation shaft 203, and as shown in fig. 3a, when the included angle α between the first housing 201 and the second housing 202 is less than 180 °, the flexible screen 10 is in a folded state.

Alternatively, as shown in fig. 3b, when the included angle α between the first housing 201 and the second housing 202 increases to 180 °, the flexible screen 10 is in the unfolded state.

Under the condition that the first casing 201 and the second casing 202 do not have the bending characteristic, the area of the flexible screen 10 connected with the first casing 201 through the glue layer cannot be bent, and the partial area is the first non-bending area 101 shown in fig. 4.

The area of the flexible screen 10 connected to the second casing 202 by the adhesive layer cannot be bent under the load of the second casing 202, and this area is the second non-bending area 102 shown in fig. 4.

In addition, in the flexible screen 10, a portion between the first non-bending region 101 and the second non-bending region 102 is a bending region 103 that enables the folding display terminal 01 to realize a bending characteristic.

On the basis, in order to support the bending region 103 of the flexible screen 10, the bending performance of the bending region 103 of the flexible screen 10 can be ensured to meet the requirement while the rigidity and the impact resistance of the bending region 103 are improved. As shown in fig. 5a, the folding assembly 20 further comprises a bending support 30.

The bending support 30 is located on the side of the rotation axis 203 facing the flexible screen 10. The bending support 30 is further connected to the first housing 201 and the second housing 202.

Illustratively, as shown in fig. 5a, a first groove 211 is provided on a surface of the first housing 201 facing the flexible screen 10. One end of the bending support 30 close to the first housing 201 may be adhered to the first groove 211 by a glue layer.

The side of the second housing 202 facing the flexible screen 10 has a second recess 212. One end of the bending support 30 near the second housing 202 may be adhered to the second groove 212 by a glue layer.

Further, in the bending support 30, an intermediate region except for a portion connected to the first case 201 and the second case 202 is connected to the rotation shaft 203.

Based on this, in order to improve the connectivity between the hinge 203 and the bending support 30, in the case that the hinge 203 includes the hinge housing 2032 as shown in fig. 2c, as shown in fig. 5b, the surface D1 where the hinge housing 2032 is connected to the bending support 30 is a plane. Thus, the contact area between the hinge housing 2032 and the bending support 30 can be increased, so that the contact between the hinge housing 2032 and the bending support 30 is firmer.

Further, as shown in fig. 5b, two end surfaces D2 and D3 of the shaft housing 2032 perpendicular to the direction of the axis O-O of the shaft 203, and a surface D4 (disposed opposite to the surface D1) of the shaft housing 2032 facing away from the bending support 30 are flat surfaces.

Thus, the end surface D2 of the shaft housing 2032 can be flush with one of the end surfaces of the first casing 201 (or the second casing 202) perpendicular to the direction of the axis O-O. Similarly, the end surface D3 of the hinge housing 2032 is flush with the other end surface of the first case 201 (or the second case 202) perpendicular to the axis O — O, thereby improving the smoothness of the appearance of the foldable display terminal 01.

Further, when the front surface D4 of the hinge housing 2032 is flat, as shown in fig. 5c, when the foldable display terminal 01 is in the unfolded state, the front surface D4 of the hinge housing 2032 is flush with the rear surface, i.e., the non-display surface, of the foldable display terminal 01, which is advantageous for improving the smoothness of the appearance of the foldable display terminal 01.

In addition, the surfaces of the spindle housing 2032 other than the surfaces D1, D2, D3, and D4 may be circular arc surfaces. Thus, as shown in fig. 6, when the foldable display terminal 01 is in a folded state, after the arc surface of the hinge housing 2032 contacts the bending support 30, the bending support 30 is bent toward the surface of the flexible screen 10 to form an arc surface, so as to support the flexible screen 10, and further, the bending of the flexible screen 10 in the bending region 103 is smoother.

As can be seen from the above description, on one hand, the bending support 30 needs to support the bending region 103, so that the bending region 103 of the flexible screen 10 has good impact resistance during the bending process of the foldable display terminal 01, and the probability of damage to the flexible screen 10 in the bending region 103 is reduced.

On the other hand, the bending support 30 also needs to have good flexibility to ensure that the maximum bending angle of the bending region 103 of the flexible screen 10 can be reached. For example, as shown in fig. 6, the bending region 103 of the flexible screen 10 and the bending support 30 can ensure that the back surface (the surface on the side facing away from the flexible screen 10) of the first housing 201 is in contact with the back surface of the second housing 202 when the bending region and the bending support are at the maximum bending angle.

To meet the above requirements, in some embodiments of the present application, as shown in fig. 7a or 7b, buckling support 30 comprises a flexible connecting layer 301 and a plurality of rigid support strips 302. The rigid support bar 302 is disposed along the axis O-O of the rotating shaft 203. In addition, a plurality of rigid support bars 302 are spaced apart and arranged side-by-side. In this case, when one end of the bending support 30 is connected to the first housing 201 and the other end is connected to the second housing 202, the plurality of rigid support bars 302 in the bending support 30 are disposed in parallel between the first housing 201 and the second housing 202. The rigidity of the material constituting the rigid support strip 302 is greater than the rigidity of the material constituting the flexible connection layer 301.

For example, the material of the rigid support bar 302 may be a metal material such as stainless steel or aluminum alloy, or may be a rigid plastic such as polyvinyl chloride (PVC).

The material constituting the flexible connection layer 301 may be a silicone material having high flexibility. In this way, the flexible material layer 301 may provide the bending support 30 with a certain flexibility, thereby ensuring that the maximum bending angle of the bending region 103 of the flexible screen 10 can be reached.

In addition, the rigid support strip 302 can provide stronger rigidity for the bending support 30, so that the bending support 30 has good support performance, and the impact resistance of the bending area 103 of the flexible screen 10 in the bending process of the foldable display terminal 01 is improved.

Hereinafter, the way of disposing the rigid support strip 302 and the flexible connecting layer 301 in the bending support 30 will be described as an example.

For example, in some embodiments of the present application, as shown in FIG. 7a, a plurality of rigid support strips 302 are located on a surface of flexible connecting layer 301. Each rigid support strip 302 is connected to a flexible connecting layer 301.

Alternatively, and for example, in other embodiments of the present application, as shown in FIG. 7b, flexible connecting layer 301 encases a plurality of rigid support strips 302. In this case, each rigid support strip 302 is peripherally covered by a flexible connecting layer 301.

In this case, for the bending support member 30 of any one of the above-described structures, the flexible connection layer 301 in the bending support member 30 may be disposed adjacent to the flexible screen 10. And the flexible connecting layer 301 is connected with the bending region 103 of the flexible screen 10 through an adhesive layer.

In addition, in the case that the bending region 103 of the flexible screen 10 is connected to the bending support 30, it is also necessary to connect the lower surface of the bending support 30 to the rotation shaft 203 so that the bending region 103 of the flexible screen 10 can be firmly connected to the folding assembly 20.

Based on this, in order to connect the lower surface of the bending support 30 with the rotating shaft 203 without affecting the rotation of the rotating shaft body 2031 in the rotating shaft 203, the folding assembly 20 further includes a connecting portion. The connecting portion is disposed between the bending support 30 and the rotating shaft 203. The connecting portion is used to connect the bending support 30 and the spindle housing 2032 of the spindle 203.

Thus, after the bending support member 30 is connected to the rotating shaft housing 2032, the bending support member 30 can fixedly connect the flexible screen 10 on the upper surface thereof and the rotating shaft 203 on the lower surface thereof, so that the bending region 103 of the flexible screen 10 can be firmly connected to the folding assembly 20, thereby reducing the probability of degumming of the flexible screen 10 in the bending region 103. In the process of bending the flexible screen 10, the phenomenon that the bending area 103 is arched due to degumming can be effectively avoided.

In addition, because a gap exists between the spindle body 2031 inside the spindle housing 2032 and the spindle housing 2032, the spindle body 2031 can still drive the first casing 201 and the second casing 202 to rotate, so that the first casing 201 and the second casing 202 are not affected by the rotation connection through the spindle 203.

It should be noted that, the structure of the rotating shaft 203 is not limited in the present application, as long as the rotating shaft 203 can be connected to the bending support 30 under the condition that the first housing 201 and the second housing 202 can be rotated by the rotating shaft 203.

The manner of disposing the connecting portion will be described in detail below.

Example 1

In this example, as shown in fig. 8, a side of the spindle housing 2032 facing the bending support 30 is provided with a mounting through hole 41.

In addition, in order to connect the bending support 30 and the spindle housing 2032 by a connection part 40 as shown in fig. 9a, a plurality of connection through holes 42 are provided on the bending support 30.

In this case, as shown in fig. 9b (cut along E-E in fig. 9 a), one connecting portion 40 passes through one connecting through hole 42 and is fitted with one mounting through hole 41.

In some embodiments of the present application, as shown in fig. 9c (an enlarged view of position F in fig. 9 b), the connecting portion 40 is a threaded fastener, such as a screw, or a bolt. In this case, the mounting through-hole 41 is a threaded through-hole. The threaded fastener is threaded into the threaded through-hole 42 after passing through the connecting through-hole 42, thereby connecting the connecting portion 40 with the mounting through-hole 41.

As a threaded fastener for the connection portion 40, a head thereof may be positioned in the connection through-hole 42, thereby connecting the connection portion 40 with the bending supporter 30. Further, the screw of the above-described threaded fastener may be screwed into the threaded through-hole to achieve the fitting of the connecting portion 40 with the mounting through-hole 41. Thereby connecting the bending supporter 30 and the spindle housing 2032 via the connection portion 40.

In addition, as shown in fig. 9c, the connection through hole 42 provided in the shaft housing 2032 is a counter bore. In this case, the threaded fastener, i.e., the head of the connecting portion 40 (the portion of the connecting portion 40 above the screw) is located in the countersunk hole, and the head of the connecting portion 40 is lower than or flush with the upper surface of the bending support 30, i.e., the surface facing the flexible screen 10.

Thus, the head of the connecting part 40 is arranged in the countersunk hole, so that the flatness of the contact surface of the bending supporting part 30 and the flexible screen 10 can be improved, and the probability of degumming of the flexible screen 10 is reduced.

As can be seen from the above, the bending support 30, as shown in fig. 7b, includes a flexible connecting layer 301 and a rigid support strip 302. In this case, in order to avoid that the connection portion 40 is stressed during the bending process of the foldable display terminal 01 to cause a large deformation of the bending support member 30, which affects the connection effect between the bending support member 30 and the hinge housing 2032, as shown in fig. 9d, the connection through hole 42 penetrates through the flexible connection layer 301 and the rigid support strip 302.

Thus, since the rigid support bar 302 can improve the rigidity of the whole bending support member 30, after the connection portion 40 passes through the connection through hole 42 penetrating through the flexible connection layer 301 and the rigid support bar 302, in the bending process of the foldable display terminal 01, the force applied to the connection portion 40 can be transmitted to the rigid support bar 302 with a larger rigidity, thereby reducing the problem that the connection effect between the bending support member 30 and the hinge housing 2032 is not good due to the larger overall deformation of the bending support member 30.

In addition, as can be seen from the above description, each of the connection portions 40 is disposed in one of the mounting through holes 41, and in order to make the plurality of connection portions 40 uniformly stressed during the bending process of the bending display terminal 01, in some embodiments of the present application, as shown in fig. 8, the plurality of mounting through holes 41 are arranged along the axis O-O of the rotation shaft 203.

The above description is given by taking the connecting portion 40 as a threaded fastener, the mounting through hole 41 on the spindle housing 2032 as a threaded through hole, and the connecting through hole 42 on the bending support 30 as a counter-sunk hole, and the bending support 30 is connected to the spindle housing 2032 through the connecting portion 40.

In other embodiments of the present application, the mounting through holes 41 of the shaft housing 2032 may be holes with the same diameter everywhere, and the connecting through holes 42 of the bending support 30 may also be holes with the same diameter everywhere. In this case, the connection portion 40 may be a pin interference-fitted with the mounting through-hole 41 and the connection through-hole 42.

Example two

In this example, as shown in fig. 8, a side of the spindle housing 2032 facing the bending support 30 is provided with a mounting through hole 41.

The cross-sectional view taken along S-S shown in fig. 10a is shown in fig. 10b, and it can be seen that the present example is different from the first example in that the connecting portion 40 is the first hook.

In this case, as shown in fig. 10c (enlarged view of the position H in fig. 10 b), a first hook, i.e., the connecting portion 40, connected to the bending support 30 extends into a mounting through hole 41 and is engaged with the inner wall of the spindle housing 2032.

The first hook needs to have a certain rigidity, so that the deformation of the foldable display terminal 01 during the bending process can be avoided, and the connection firmness between the bending support member 30 and the hinge housing 2032 can be affected. In addition, in order to simplify the manufacturing process of the first hook, in some embodiments of the present application, in the case that the bending support member 30 includes the rigid support strip 302, the first hook, i.e., the connecting portion 40, may be made of the same material as the rigid support strip 302 with higher rigidity and be an integral structure.

In this case, the position of the first hook may be completed while the rigid support bar 302 is formed through a one-time injection molding process.

In addition, in order to further improve the connection firmness of the bending support member 30 and the hinge housing 2032, as shown in fig. 10c, at least one rigid support strip 302 of the bending support member 30 extends out of at least one end of the flexible connection layer 301. On the basis, the folding assembly 20 further comprises a plurality of second hooks 401 and third hooks 411 as shown in fig. 10 c.

The second hook 401 is connected to the portion of the rigid support bar 302 extending out of the flexible connection layer 301. As mentioned above, the second hook 401 may be made of the same material as the rigid supporting bar 302 and is an integral structure.

The third hook 411 is disposed on an end surface (perpendicular to the axis O-O of the shaft 203) of the shaft housing 2032. In this case, a second hook 401 is engaged with a third hook 411. Therefore, the two ends of the rotating shaft housing 2032 can also be connected to the bending support 30, so as to improve the connection firmness of the two.

In addition, the third hook 411 may be made of the same material as the shaft housing 2032 and is of an integral structure. In this case, the third hook 411 may be manufactured by a one-time injection molding process while the shaft housing 2032 is manufactured.

The shaft housing 2032 is provided with a mounting through hole 41

Example three

In this example, the connection portion 40 is a glue layer as shown in fig. 11. In this case, the bending supporter 30 may be connected to the spindle housing 2032 of the spindle 203 by a glue layer.

In this case, as shown in fig. 5b, the surface D1 where the shaft housing 2032 is connected to the bending support 30 is a plane. Thus, the glue spreading area of the spindle housing 2032 can be increased, so that the spindle housing 2032 is more firmly contacted with the bending support 30 through the glue layer.

In summary, the folding assembly 20 in the folding display terminal 01 provided by the embodiment of the present application includes a first housing 201, a second housing 202, and a rotating shaft 203 for rotatably connecting the first housing 201 and the second housing 202. The spindle 203 includes a spindle body 2031 and a spindle housing 2032. The first housing 201 and the second housing 202 are respectively connected to the shaft body 2031. The first casing 201 is connected to the first non-bending region 101 of the flexible screen 10, and the second casing 202 is connected to the second non-bending region 102 of the flexible screen 10. For carrying the flexible screen 10 to ensure the flatness of the flexible screen.

In addition, the folding assembly 20 includes a bending support 30 connected to the bending region 103 of the flexible screen 10. The bending support 30 includes a structure capable of providing support to the flexible screen 10 and bending the flexible screen 10 to a maximum angle.

The lower surface of the bending support 30 is connected to the first housing 201 at a portion close to the first housing and to the second housing 202 at a portion close to the second housing 202. In addition, the middle portion of the lower surface of the bending support 30 can be connected to the main body 2031 of the spindle 203 in the manner provided in the first, second and third examples.

In this case, the bending support 30 can fixedly connect the flexible screen 10 on the upper surface thereof and the rotating shaft 203 on the lower surface thereof, so that the bending region 103 of the flexible screen 10 can be firmly connected to the folding assembly 20, thereby reducing the probability of degumming in the bending region 103 of the flexible screen 10 and avoiding the arching phenomenon of the flexible screen 10. In addition, since the spindle body 2031 and the spindle housing 2032 have a gap therebetween, the spindle body 2031 can rotate within the spindle housing 2032 even if the bending support 30 is connected to the spindle housing 2032.

The above description is only an embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions within the technical scope of the present disclosure should be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
