The electronic device disclosed in the embodiments of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1 to 65, the present application discloses an electronic device including a first body 100, a second body 800, a moving support 200, a lifting support 300, a linkage 400, and a flexible display screen 900.

The first body 100 and the second body 800 are basic components of an electronic device, and are used for providing a mounting base for other components of the electronic device, and the first body 100 and the second body 800 are movably connected, that is, the second body 800 is movable relative to the first body 100, so that at least a part of the first body 100 and at least a part of the second body 800 can move toward or away from each other, and the electronic device is switched between a folded state and an unfolded state.

The flexible display screen 900 is a display component of the electronic device, one end of the flexible display screen 900 is connected to the first main body 100, and the other end of the flexible display screen is connected to the second main body 800, and the flexible display screen 900 is easy to deform, so that when the electronic device is switched between the folded state and the unfolded state, the display area of the flexible display screen 900 can be gradually reduced or gradually increased to meet different use requirements of users.

The moving support member 200 and the lifting support member 300 are both used for supporting the flexible display screen 900, that is, the moving support member 200 and the lifting support member 300 are support carriers of the flexible display screen 900, specifically, the moving support member 200 is used for supporting the flexible display screen 900 when the electronic device is in the folded state, and the lifting support member 300 and the moving support member 200 jointly support the flexible display screen 900 when the electronic device is in the unfolded state, so as to ensure that the flexible display screen 900 can normally work.

Specifically, the lifting support 300 is movably disposed at the first body 100, the moving support 200 is disposed at the second body 800, the moving support 200 is movable relative to the first body 100 when the first body 100 and the second body 800 relatively move, and a moving direction of the moving support 200 intersects with a moving direction of the lifting support 300. Alternatively, the moving direction of the moving support 200 and the moving direction of the elevating support 300 are perpendicular to each other.

The link 400 is movably disposed on the first body 100, and when the movable support 200 is connected to the link 400, the movable support 200 drives the elevating support 300 to move through the link 400, that is, the movement of the movable support 200 drives the link 400 to move relative to the first body 100, so that the link 400 drives the elevating support 300 to move relative to the first body 100. Alternatively, the moving direction of the link 400 may be parallel to the moving direction of the moving support 200.

Under the condition that the electronic device is in the unfolded state, the moving support 200 moves to the first position, so that the lifting support 300 is lifted to the first height, that is, the height of the lifting support 300 in the arrangement direction of the moving support 200 and the lifting support 300 is increased, so that both the moving support 200 and the lifting support 300 are abutted against the flexible display 900, and the flexible display 900 is supported together. Alternatively, in the moving direction of the moving support 200, there is a gap between the moving support 200 and the first body 100, and the first position may be a position where the moving support 200 is located when the gap is at a maximum.

Under the condition that the electronic device is in the folded state, the movable support 200 moves to the second position, so that the lifting support 300 is lowered to the second height, even if the height of the lifting support 300 in the direction in which the movable support 200 and the lifting support 300 are arranged is lowered, the movable support 200 covers the lifting support 300, so that the movable support 200 abuts against the flexible display 900, that is, the flexible display 900 is supported only by the movable support 200 at this time. Optionally, the first height is greater than the second height.

In the embodiment of the present application, the moving support 200 and the lifting support 300 are movable relative to the first body 100, and the moving directions of the moving support and the lifting support 300 are crossed, so that the lifting support 300 can support the flexible display screen 900 together with the moving support 200 by lifting itself, and can also avoid the moving support 200, so that the moving support 200 can be retracted and cover at least a portion of the lifting support 300. Therefore, the embodiment of the application can support the flexible display screen 900 together by the movable support member 200 and the lifting support member 300 when the electronic device is unfolded, so that a better supporting effect is provided, and meanwhile, the movement of the movable support member 200 and the movement of the lifting support member 300 do not interfere with each other, so that the friction between the two is alleviated, and the problem that the electronic device in the related art has abnormal sound is solved.

Alternatively, one of the elevating support 300 and the linkage member 400 is provided with a driving slope 310, and the other is provided with a driving protrusion 410, and in the case that the driving slope 310 is matched with the driving protrusion 410, the linkage member 400 can drive the elevating support 300 to move by the matching of the driving slope 310 and the driving protrusion 410, i.e., the movement of the linkage member 400 can make the driving slope 310 and the driving protrusion 410 match to raise the elevating support 300 to the first height to support the flexible display screen 900, or the movement of the linkage member 400 can make the driving slope 310 and the driving protrusion 410 separate to lower the elevating support 300 to the second height. This embodiment can realize the movement of the elevating support 300 by the force generated between the driving slope 310 and the driving protrusion 410, which has the characteristics of simple structure, small occupied space, etc.

The number of the driving inclined plane 310 and the driving protrusion 410 may be one, but when the electronic device is in the unfolded state, because the size of the lifting support 300 is large, when the driving inclined plane 310 is matched with the driving protrusion 410, there may be a case where a part of the lifting support 300 is raised to the first height to abut against the flexible display 900, and another part of the lifting support 300 is not in contact with the flexible display 900, that is, the lifting support 300 has a poor supporting effect on the flexible display 900.

In order to avoid the above situation, in another embodiment, the number of the driving slopes 310 and the driving protrusions 410 is at least two, and each driving slope 310 and each driving protrusion 410 are in one-to-one correspondence, and in order to enable the lifting support 300 to support the flexible display screen 900 more stably, the driving slopes 310 or the driving protrusions 410 may be disposed on the lifting support 300 or the linkage 400 at intervals, so that each part of the lifting support 300 is abutted against the flexible display screen 900, thereby improving the supporting effect of the flexible display screen 900.

Alternatively, the driving protrusion 410 may be a fixedly disposed protrusion, or may also be a driving roller, the driving roller is rotatably disposed on the lifting support 300 or the linkage 400, that is, when the linkage 400 moves, the driving roller is rotatably engaged with the driving inclined plane 310, so that the lifting support 300 can be raised to the first height or lowered to the second height, and meanwhile, friction force can be reduced by the rolling engagement, which not only facilitates the movement of the lifting support 300, but also reduces wear. Alternatively, one of the elevating support 300 and the link 400 is further provided with a roller shaft 430 and a roller shaft mounting hole 440, the driving roller is rotatably disposed on the roller shaft 430, and both ends of the roller shaft 430 are disposed in the roller shaft mounting hole 440, whereby the driving roller can be rotatably disposed on the elevating support 300 or the link 400.

Alternatively, the linkage 400 may be driven to move by an additional driving device, but the additional driving device occupies more space due to the limited space of the electronic device, which may affect the arrangement of other components.

In another embodiment, the movable support member 200 is provided with a first pulling portion 210, the linkage member 400 is provided with a second pulling portion 420, when the electronic device is in a folded state, the first pulling portion 210 and the second pulling portion 420 are arranged at intervals along the moving direction of the movable support member 200, when the first pulling portion 210 is connected to the second pulling portion 420, the movable support member 200 drives the linkage member 400 to move through the cooperation of the first pulling portion 210 and the second pulling portion 420, and the moving directions of the movable support member 200 and the linkage member 400 are the same. Therefore, when the movable supporting member 200 moves to the first position, the first drawing part 210 is connected to the second drawing part 420, so that the first drawing part 210 drives the second drawing part 420 to move in the same direction, and the linkage member 400 drives the lifting supporting member 300 to move, that is, the first drawing part 210 arranged on the movable supporting member 200 drives the second drawing part 420 arranged on the linkage member 400 to drive the linkage member 400 to move, so that the application does not need to additionally arrange a driving device, and the influence on the installation space of the electronic device is small, and meanwhile, the arrangement mode can also avoid the condition that the lifting supporting member 300 moves in advance, and the arrangement mode has small operation difficulty and is easy to control.

Alternatively, in a state where the electronic apparatus is in a folded state, the first pulling part 210 may be located at an end of the moving support 200 away from the second pulling part 420, and when the first pulling part 210 is connected to the second pulling part 420, the moving support 200 may be free from a large space for the lifting support 300 to move relative to the first body 100.

Alternatively, the moving support 200, the lifting support 300, and the linkage 400 may be all plate-shaped structures, the lifting support 300 and the linkage 400 are arranged in the moving direction of the lifting support 300, and in the case that the electronic device is in the folded state, the moving support 200, the lifting support 300, and the linkage 400 are sequentially arranged in the moving direction of the lifting support 300, so that the size of the electronic device in the folded state is reduced, and the portability of the electronic device is improved.

Optionally, in the process of switching the electronic device to the folded state, the movable support 200 is not connected to the linkage member 400, and in order to enable the lifting support 300 to be quickly lowered to the second height so as to avoid blocking the movement of the movable support 200, the electronic device further includes a first elastic member 510, the first elastic member 510 is connected between the first main body 100 and the linkage member 400, in the process of switching the electronic device to the unfolded state, the first elastic member 510 is stretched by the movable support 200 through the linkage member 400, and in the process of switching the electronic device to the folded state, the first elastic member 510 recovers deformation to drive the linkage member 400 to move, so that no acting force is generated between the driving inclined surface 310 and the driving protrusion 410, and the lifting support 300 is quickly lowered to the second height under its own gravity.

In order to further rapidly lower the lifting support 300 to the second height, in another embodiment, the electronic device further includes a second elastic member 520, the second elastic member 520 is connected between the first body 100 and the lifting support 300, and during the switching process of the electronic device to the unfolded state, the driving inclined surface 310 and the driving protrusion 410 are engaged to make the lifting support 300 move away from the first body 100 and raise to the first height, at this time, the second elastic member 520 is stretched, so that during the switching process of the electronic device to the folded state, the second elastic member 520 recovers its shape, so as to drive the lifting support 300 to move toward the first body 100 more rapidly, even though the lifting support 300 can be lowered to the second height more rapidly, so as to avoid blocking the movement of the moving support 200.
