Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.

Referring to fig. 1 to 4, fig. 1 is a first structural schematic diagram of a display device according to an embodiment of the present disclosure, fig. 2 is a second structural schematic diagram of the display device according to the embodiment of the present disclosure, fig. 3 is a cross-sectional view of the display device shown in fig. 1 along a direction P1-P1, and fig. 4 is a cross-sectional view of the display device shown in fig. 2 along a direction P2-P2. The display device 20 includes a first moving body 100, a second moving body 200, and a flexible screen assembly 300. The first and second moving

bodies

100 and 200 are slidably connected such that the first and second moving

bodies

100 and 200 are relatively moved in a direction approaching or separating from each other, so that switching of the display device 20 between the unfolded state and the folded state can be achieved. In this case, a collapsed state of the display device 20 may be referred to as fig. 1, i.e., a state in which the first moving body 100 and the second moving body 200 are relatively moved in a direction to approach each other and finally formed. In this case, the display device 20 may be in an unfolded state as shown in fig. 2, that is, a state in which the first moving body 100 and the second moving body 200 are relatively moved in a direction away from each other.

It should be understood that the first moving body 100 and the second moving body 200 are spread out from each other when the display device 20 is in the spread state, and the state of the first moving body 100 and the second moving body 200 may also be understood as being in the spread state. When the display device 20 is in the collapsed state, the first moving body 100 and the second moving body 200 are collapsed with each other, and the state of the first moving body 100 and the second moving body 200 may also be understood as being in the collapsed state.

It should be noted that the display device 20 may have a plurality of unfolding states, or the first moving body 100 and the second moving body 200 may have a plurality of unfolding states, such as the maximum moving distance of the first moving body 100 and the second moving body 200 in the direction away from each other is L, and the first moving body 100 and the second moving body 200 may move away from each other in the folded state, so as to achieve the unfolding states with different distances formed by equal distances of one quarter L, one half L, and three quarters L. The state in which the distance becomes gradually farther may be defined as a first developed state, a second developed state, a third developed state, and the like in this order.

It should be noted that, when the first moving body 100 and the second moving body 200 are in the first deployed state, such as the distance of the relative distancing movement of the first moving body 100 and the second moving body 200 in the first deployed state is one quarter L, the first moving body 100 and the second moving body 200 may still perform the distancing movement with respect to each other to reach the second deployed state, such as the distance of the relative distancing movement of the first moving body 100 and the second moving body 200 in the second deployed state is one half L.

It is to be understood that the one or more development states of the first moving body 100 and the second moving body 200 of the embodiment of the present application are merely illustrative and do not constitute a limitation on the development states of the first moving body 100 and the second moving body 200 of the embodiment of the present application.

The first moving body 100 and the second moving body 200 may be electrically driven to move relative to each other, such as one or more driving motors, as many transmission assemblies as the motors are provided, and a transmission assembly may include one or more gears, one or more racks, one or more transmission belts, or the like. The driving motor may drive the first and second moving

bodies

100 and 200 to move close to or away from each other through the transmission assembly. Of course, the first and second moving

bodies

100 and 200 may be driven to move closer to or away from each other manually.

One end of the flexible screen assembly 300 is fixedly connected to the first moving body 100, and the other end of the flexible screen assembly 300 is fixedly connected to the second moving body 200. The first and second moving

bodies

100 and 200 may support the flexible screen assembly 300. The first moving body 100 and the second moving body 200 may drive the flexible screen assembly 300 to move together or drive the flexible screen assembly 300 to move during the mutual movement, so that the length of the flexible screen assembly 300 may be adjusted, and the size of the display area of the display device 20 may be changed. It should be noted that both ends of the flexible screen assembly 300 may also be fixed to the first moving body 100 or the second moving body 200 at the same time, and the flexible screen 300 may also be driven to move together during the mutual movement of the first moving body 100 and the second moving body 200, so as to adjust the size of the display area of the display device 20.

When the first and second moving

bodies

100 and 200 are relatively moved in a direction to approach each other, the first and second moving

bodies

100 and 200 may drive a portion of the flexible screen assembly 300 to be received inside the display device 20. When the first and second moving

bodies

100 and 200 are relatively moved in a direction away from each other, the first and second moving

bodies

100 and 200 may drive a portion of the flexible screen assembly 300 to protrude from the inside of the display device 20.

The non-display surface of the flexible screen assembly 300 may be disposed on one surface of the first moving body 100 and one surface of the second moving body 200, or the non-display surface of the flexible screen assembly 300 may be disposed on one surface of the first moving body 100 and one surface of the second moving body 200. The flexible screen assembly 300 may cover one surface of the first moving body 100 and one surface of the second moving body 200 regardless of whether the first moving body 100 and the second moving body 200 are in the collapsed state or in the expanded state, and the covered areas are different in size.

When the first moving body 100 and the second moving body 200 are in the collapsed state, a part of the other face of the second moving body 200 is located inside the first moving body 100. Or when the first moving body 100 and the second moving body 200 are in the folded state, a part of the second moving body 200 is received in the first moving body 100, and at this time, the other surface of the second moving body 200 is shielded by the first moving body 100. And the other side of the first moving body 100 may serve as a housing of the display device 20. When the first moving body 100 and the second moving body 200 are in the deployed state, a portion of the other face of the second moving body 200 is located outside the first moving body 100, or is exposed outside, or is not shielded by the first moving body 100.

With continued reference to fig. 3 and 4, the first moving body 100 and the second moving body 200 may be slidably connected by one or more sets of sliding assemblies 400, so as to change the relative positions of the first moving body 100 and the second moving body 200. The sliding assembly 400 may connect the first moving body 100 and the second moving body 200, and the sliding assembly 400 may enable the relative movement of the first moving body 100 and the second moving body 200.

In an alternative embodiment of the present application, the set of sliding assemblies 400 may include a sliding body, and it is understood that the set of sliding assemblies 400 is a one-stage sliding rail solution. One sliding body may connect the first moving body 100 and the second moving body 200 to realize the relative movement of the first moving body 100 and the second moving body 200. It should be understood that, due to the design of one slide rail, the distance that the first and second moving

bodies

100 and 200 move relative to each other based on one slide rail is limited, and there is a limit to the ability to adjust the size of the display area of the display device 20.

In other alternative embodiments of the present application, the set of sliding assemblies 400 may include at least two sliding bodies, and it is understood that the set of sliding assemblies 400 is a multi-stage sliding rail scheme. With continued reference to fig. 3 and 4, a set of sliding assemblies 400 according to the present disclosure is illustrated as including two sliding bodies, and a set of sliding assemblies 400 may include a first sliding body 410 and a second sliding body 420. The first slider body 410 and the second slider body 420 may move relative to each other. Compared with a set of sliding assemblies 400 having only one sliding body, the embodiment of the present application may increase the sliding distance of the sliding assembly 400 through the relative movement of the first sliding body 410 and the second sliding body 420, may increase the amount of movement of the first moving body 100 and the second moving body 200 that move relative to each other, and may further improve the capability of adjusting the size of the display area of the display device 20.

In order to ensure that the first and second moving

bodies

100 and 200 can move relatively by the sliding assembly 400, at least one of the first and second moving

bodies

100 and 200 needs to guide and limit the sliding assembly 400. Such as the first moving body 100, is provided with a structure for restraining the sliding assembly 400. Referring to fig. 5 and 6, fig. 5 is a schematic structural diagram of a first moving body in the display device shown in fig. 1 and 2, and fig. 6 is an enlarged view of a layout F in the first moving body shown in fig. 5. As shown in fig. 5 and 6, the first moving body 100 is provided with one or more guide grooves 160, and a set of sliding members 400 can slide in a space defined by one guide groove 160. The guide groove 160 can also be understood as a sliding groove and also as a sliding space.

Referring to fig. 7 to 12, fig. 7 is a schematic view of a structure in which a first moving body, a sliding assembly and a pressing assembly are matched with each other in the display device shown in fig. 1 and 2, fig. 8 is an enlarged view of a portion G in the display device shown in fig. 7 in which the first moving body and the sliding assembly are matched with each other, fig. 9 is another schematic view of a structure in which the first moving body and the sliding assembly are matched with each other in the display device shown in fig. 1 and 2, fig. 10 is an enlarged view of a portion H in the display device shown in fig. 9 in which the first moving body and the sliding assembly are matched with each other, fig. 11 is a schematic view of a portion K in the display device shown in fig. 1 and 2 in which the first moving body, the second moving body and the sliding assembly are matched with each other, and fig. 12 is an enlarged view of a portion K in the display device shown in fig. 11 in which the first moving body, the second moving body and the sliding assembly are matched with each other. Wherein, fig. 7 and 8 show that the sliding assembly 400 is received in the guide groove 140 of the first moving body 100. Among them, fig. 9 to 12 show that a part of the sliding assembly 400 is protruded to the outside of the first moving body 100.

Taking two sets of sliding assemblies 400 as an example in the embodiment of the present application, please refer to fig. 5 to 12, the two sets of sliding assemblies 400 are disposed at intervals, and the first moving object 100 and the second moving object 200 can realize relative movement through the two sets of sliding assemblies 400. The two sets of sliding members 400 may be disposed on the first moving body 100 and connected to the second moving body 200. The two sets of sliding assemblies 400 can slide on the first moving body 100 synchronously to drive the second moving body 200 and the flexible screen assembly 300 to move. The two sets of sliding members 400 may be spaced apart by the battery well 120 of the first moving body 100, and the battery well 120 of the first moving body 100 may be used to house a battery of the display device 20. The outer side of each set of slide assemblies 400 may be disposed with wiring of the display device 20 such as a circuit board structure.

When each set of sliding assemblies 400 includes at least two sliding bodies, the two adjacent sliding bodies can slide with each other, the sliding body far away from the second moving body 200 is disposed on the first moving body 100 and can slide in the guide slot 160 of the first moving body 100, and the sliding body far away from the first moving body 100 is connected to the second moving body 200. Referring to fig. 13, fig. 13 is an exploded view of the display device shown in fig. 1 and 2, such as a first sliding body 410 and a second sliding body 420 which can slide together on the first moving body 100, and in particular can slide in the guide groove 160 of the first moving body 100. And the first sliding body 410 is directly disposed in the guide groove 160, the second sliding body 420 can slide on the first sliding body 410. A sliding space for the second sliding body 420 to slide may be opened on the first sliding body 410.

For another example, the sliding assembly 400 may include a third sliding body, a fourth sliding body and a fifth sliding body, the third sliding body is disposed on the first moving body 100 and can slide on the first moving body 100, the fourth sliding body is disposed on the third sliding body and can slide on the third sliding body, the fifth sliding body is disposed on the fourth sliding body and can slide on the fourth sliding body, and the fifth sliding body is connected to the second moving body 200.

It should be noted that, when the first moving body 100, the second moving body 200 and the sliding assembly 400 are actually assembled, due to the influence of the processing technology of the first moving body 100, the second moving body 200 and the sliding assembly 400 and the influence of the assembly tolerance of the first moving body 100, the second moving body 200 and the sliding assembly 400, a certain gap is formed between the sliding assembly 100 and the second moving body 200 after the sliding assembly 400 is assembled in the guide slot 160, so that the sliding assembly 400 shakes during sliding in the guide slot 160, and the first moving body 100 and the second moving body 200 of the display device 20 shake, which affects the user experience.

It should be further noted that, the sliding assembly 400 is a multi-stage sliding rail scheme, that is, the sliding assembly 400 includes a plurality of sliding bodies such as a first sliding body 410 and a second sliding body 420, the first sliding body 410 and the second sliding body 420 can slide with respect to each other, one of the sliding bodies is guided and limited by the other sliding body, so that the limit of the first moving body 100 and the second moving body 200 to the whole sliding assembly 400 is shortened, and further the situation that the sliding assembly 400 shakes during sliding in the guide groove 160 is more obvious, and then the first moving body 100 and the second moving body 200 of the display device 20 shake more seriously, which seriously affects user experience.

In view of this, the pressing member 500 is mounted between the sliding member 400 and at least one of the first moving body 100 and the second moving body 200 in the embodiment of the present application, and the pressing member 500 can apply a force to the sliding member 400 in a first direction to press the sliding member 400, wherein the first direction is perpendicular to the sliding direction of the sliding body, such as the first sliding body 410. Therefore, the embodiment of the present application can reduce the shaking of the sliding assembly 400 during the sliding process, and the acting force applied to the sliding assembly 400 by the pressing assembly 500 can also be applied to the first moving body 100 and/or the second moving body 200 through the sliding assembly 400, so as to reduce the shaking of the mutual movement of the first moving body 100 and the second moving body 200. When the sliding assembly 400 includes a plurality of sliding members, such as the first sliding body 410 and the second sliding body 420, the force applied to the sliding assembly 400 by the pressing assembly 500 can be applied between the first sliding body 410 and the second sliding body 420, so that the shaking between the first sliding body 410 and the second sliding body 20 can be reduced, and the first sliding body 410 and the second sliding body 420 can be further limited.

Referring to fig. 14 and 15, fig. 14 is an enlarged view of a portion X of the display device shown in fig. 3, and fig. 15 is an enlarged view of a layout Y of the display device shown in fig. 4. Referring to fig. 3 and 4, the pressing assembly 500 includes an elastic member 540 and a rolling member 520 disposed on the first moving body 100, wherein the elastic member 540 is used for applying an elastic force to drive a portion of the rolling member 520 to be exposed out of the bottom wall surface of the sliding space 160, so that the rolling member 520 applies a force to the sliding assembly 400. When the sliding assembly 400 slides in the sliding space 160, the rolling member 520 can be driven to roll. The elastic member 540 includes one or more of a spring, an elastic sheet, and a plastic member with elasticity, and the elastic member 540 according to the embodiment of the present disclosure is exemplified by a spring. The rolling members 520 include balls and/or rollers, and the rolling members 520 in the embodiment of the present application are exemplified by balls.

In an alternative embodiment of the present application, the pressing assembly 500 further includes a bracket 560, the bracket 560 abuts against the elastic member 540, the bracket 560 has a receiving space 562, the rolling member 520 is disposed in the receiving space 562, and the elastic member 540 is further configured to apply a force to drive a portion of the rolling member 520 exposed to the bottom wall surface of the sliding space 160 through the bracket 560. The elastic member 540 of the embodiment of the present application can push up the bracket 560 and the rolling member 520 disposed in the bracket 560 together, so as to ensure that the gap between the sliding assembly 400 and the corresponding guide groove 160 is reduced, and the shaking is reduced. Meanwhile, the gap between the first sliding body 410 and the second sliding body 420 in the sliding assembly 400 can be reduced, and the shaking can be further reduced, so that the stability of the relative movement of the first moving body 100 and the second moving body 200 in the display device 20 is improved, and the user experience is improved.

As shown in fig. 3, 4, 14 and 15, in which a first gap a is formed between the sliding assembly 400 and the first moving body 100, it should be understood that the elastic member 540 applies a force to the bracket 560 to drive the bracket 560 and the rolling member 520 therein to press against the sliding assembly 400, so as to adjust the first gap a in the floating state, and thus to perform a self-adaptive function, the larger the value of the first gap a, the larger the displacement of the elastic member 540 driving the bracket 560 and the rolling member 520 to press against. Similarly, when the sliding assembly 400 includes a plurality of sliding bodies, a second gap B exists between two adjacent sliding bodies, such as the first sliding body 410 and the second sliding body 420, it should be understood that the bracket 560 and the rolling member 520 therein can be driven to press against the first sliding body 410 by the elastic member 540 according to the embodiment of the present application, so as to adjust the second gap B in the floating state to perform a self-adaptive function, and the larger the value of the second gap B, the larger the displacement amount of the elastic member 540 driving the bracket 560 and the rolling member 520 to press against is. And then the shaking amount of the whole machine is adaptively optimized, and the rolling part 520 adopts rolling balls to have rolling friction with the sliding component 400, so that the friction force is small, the motion resistance is reduced, the sliding of the sliding component 400 cannot be limited too much, and the service life of the whole machine is prolonged. Therefore, the embodiment of the present application can solve the problem that the whole machine shakes due to the influence of the processing processes of the parts, such as the first moving body 100, the second moving body 200, and the sliding assembly 300, and also solve the problem that the whole machine shakes due to the influence of the tolerance in the assembling process of the first moving body 100, the second moving body 200, and the sliding assembly 300. In addition, the embodiment of the present application can solve the problem that the gap between the first moving body 100, the second moving body 200, and the sliding assembly 300 is increased due to long-term use.

Referring to fig. 5 and 6 together, the first moving body 100 is provided with a receiving groove 140, the

elastic members

540 and 560 are disposed in the receiving groove 140, and a portion of the rolling member 520 is located in the receiving groove 140.

It should be understood that the pressing assembly 500 is plural, and the pressing assemblies 500 may be arranged at intervals, and the arrangement direction of the pressing assemblies 500 is parallel to the sliding direction of the sliding assembly 400. Correspondingly, the number of the receiving grooves 140 formed in the first moving body 100 may be multiple, and is the same as the number of the pressing members 500.

It should be further understood that when there are at least two sets of sliding assemblies 400, there are at least two sets of pressing assemblies 500, and at least two sets of pressing assemblies 400 are spaced apart from each other. I.e., a set of jacking assemblies 500 in cooperation with a set of sliding assemblies 400.

The distance that the first and second moving

bodies

100 and 200 slide through the sliding assembly 400 is equal to the sum of the strokes of all the sliding bodies, and the size that the flexible screen assembly 300 is stretched out to the outside of the first and second moving

bodies

100 and 200 as the second and first moving

bodies

200 and 100 slide or the size that the flexible screen assembly 300 is received into the first and second moving

bodies

100 and 200 from the outside of the first and second moving

bodies

100 and 200 as the second and first moving

bodies

200 and 100 slide is equal to the sum of the strokes of all the sliding bodies. That is, the sliding assembly 400 of the embodiment of the present application travels a distance equal to the traveling distance of the first and second moving

bodies

100 and 200 and equal to the traveling distance of the flexible screen assembly 300. As shown in fig. 3, 4, 14 and 15, the stroke of the movement of the flexible screen assembly 300 is the sum of the stroke D of the first sliding body 410 and the stroke C of the second sliding body 420.

In the embodiment of the present invention, when the sliding assembly 400 includes a plurality of sliding bodies, the pressing assembly 500 can also be disposed between two adjacent sliding bodies.
