Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that some, but not all embodiments of the application are described. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The electronic device provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

As shown in fig. 1 to 16, an embodiment of the present application discloses an electronic device including a flexible screen 100, a frame assembly 200, and a support assembly 300. The flexible screen 100 is a component for providing a display function in an electronic device, and the frame assembly 200 and the support assembly 300 may be regarded as a housing for providing a mounting base and protection for other components in the electronic device.

The flexible screen 100 may be deformed during the use of the electronic device, and in order to ensure that the electronic device has the capability of increasing the display area in multiple directions, further, the flexible screen 100 disclosed in the embodiment of the present application is a flexible stretchable structure, that is, the flexible screen 100 has the capability of being stretched while having the capability of being bendable and deformed, which makes the display area of the flexible screen 100 variable.

More specifically, when such a flexible screen 100 is stretched by a force in a certain direction, the dimension of the flexible screen 100 in that direction may be changed, thereby causing the flexible screen 100 to exert an effect of being stretched in that direction; and, this flexible screen 100 utilizes the structure constitution of self specific form for flexible screen 100 can produce tensile deformation in the aforesaid direction, and when flexible screen 100's overall dimension changed, make this flexible screen 100 can not appear the circumstances of distortion, and then guarantee that flexible screen 100 is all better in the display effect around the deformation.

In order to enable the electronic device to have both a large display area and a strong portability, a portion of the flexible screen 100 may be connected to the support assembly 300, and in a state where the electronic device is in a folded state, another portion of the flexible screen 100 may be received in the frame assembly 200; and, by having the frame assembly 200 and the support assembly 300 movably coupled in the first direction, the electronic device is enabled to switch between the unfolded state and the folded state, and the size of the portion of the flexible screen exposed outside the frame assembly 200 in the first direction is changed.

That is, in the present application, a part of the structure in the flexible screen 100 may be received by the frame assembly 200, in which case the display area of the portion of the electronic device exposed to the outside is relatively small; meanwhile, by making the frame assembly 200 and the support assembly 300 in a state of being stacked or crossed with each other, the sizes of the two in the first direction can be relatively small, so that the whole electronic device is ensured to have strong portability. Accordingly, since the frame assembly 200 and the support assembly 300 can move relatively in the first direction, in the process of relatively moving away from each other along the first direction, the portion of the flexible screen 100 stored in the frame assembly 200 can be exposed, so as to increase the effective display area of the flexible screen 100.

Specifically, the accommodating cavity may be formed in the frame assembly 200 to provide an accommodating function for a part of the structure of the flexible screen 100, and the frame assembly 200 may be provided with an accommodating shaft and other structures, so that a part of the flexible screen may be accommodated in the outer periphery of the accommodating shaft in a winding manner, which may reduce the accommodating difficulty of the flexible screen 100, and may prevent the flexible screen 100 from being damaged due to excessive folding, thereby improving the service life of the flexible screen 100.

Based on the flexible screen 100 with the stretchable capability, in order to further enlarge the display area of the flexible screen 100 when the electronic device is in the unfolded state, the support assembly 300 in the electronic device disclosed in the embodiment of the application includes a first support portion 310 and a second support portion 320 movably matched along a second direction, where the second direction is perpendicular to the first direction.

As described above, the flexible screen 100 is connected to the support assembly 300, in this embodiment, the edges of the two opposite sides of the flexible screen 100 along the second direction may be fixed to the first support portion 310 and the second support portion 320, respectively, and since the flexible screen 100 disclosed in the embodiment of the present application has the capability of being stretched, when the first support portion 310 and the second support portion 320 move opposite to each other along the second direction, the first support portion 310 and the second support portion 320 can provide a stretching force to the flexible screen 100, so as to increase the size of the flexible screen 100 along the second direction; accordingly, when the first support part 310 and the second support part 320 are moved toward each other in the second direction, the flexible screen 100 is allowed to resume the deformation, reducing the size of the flexible screen 100 in the second direction. Of course, in other embodiments of the present application, if the structural composition of the support assembly 300 is changed, the specific connection relationship between the flexible screen 100 and the support assembly 300 may be changed correspondingly.

That is, in the electronic device disclosed in the embodiment of the present application, the housing may not only be deformed in the first direction to expand the size of the housing in the first direction, but also be deformed in the second direction perpendicular to the first direction, so as to expand the size of the housing in the second direction, which makes it possible to increase the display size of the flexible screen 100 in the first direction by increasing the exposed portion of the flexible screen 100 in the electronic device, and increase the display size of the flexible screen 100 in the second direction by deforming the flexible screen 100, thereby increasing the degree of increase in the display area of the flexible screen 100. Of course, in the design process of the electronic device, the size of the exposed portion can be increased by correspondingly controlling the size of the flexible screen 100 in the first direction based on the expansion multiple of the size of the flexible screen 100 in the second direction through deformation, so that no matter what state the flexible screen 100 is in, the aspect ratio of the flexible screen 100 can be ensured to be relatively coordinated, the software suitability of the flexible screen 100 in the electronic device disclosed by the embodiment of the application is improved, and further the user experience is improved. The width in the "aspect ratio" may specifically be the first direction, and the length may specifically be the second direction.

In the use process of the electronic device disclosed in the above embodiment, the user may push and pull the frame assembly 200 and the support assembly 300 in the first direction by using both hands, so as to reduce or increase the size of the exposed portion of the flexible screen 100 in the first direction; accordingly, the first support portion 310 and the second support portion 320 may be moved toward or away from each other in the second direction by manual driving, so as to reduce or increase the size of the flexible screen 100 in the second direction.

In other words, the electronic device has an unfolded state and a folded state, in the folded state, a portion of the flexible screen is rolled up in the frame assembly, and another portion of the flexible screen is supported by the support assembly, and a display portion of the flexible screen exposed out of the frame assembly has a first dimension in a first direction and a second dimension in a second direction.

As described above, in the process of switching the electronic device from the folded state to the unfolded state, the frame assembly 200 and the support assembly 300 can be separated from each other in the first direction, and the first support portion 310 and the second support portion 320 can also be separated from each other in the second direction, so as to increase the size of the portion of the flexible screen 100 exposed outside the frame assembly 200.

Specifically, in the unfolded state, the flexible screen is supported by the frame assembly 200 and the support assembly 300, the display portion of the flexible screen exposed outside the frame assembly has a third dimension in the first direction, the display portion has a fourth dimension in the second direction, the third dimension is greater than the first dimension, and the fourth dimension is greater than the second dimension. That is, the flexible screen in the unfolded state is relatively larger in both the first direction and the second direction than the flexible screen in the folded state, thereby providing a better use experience.

In order to ensure that the portion of the flexible screen 100 that can be received in the frame assembly 200 can also be deformed in the second day direction along with the first portion connected to the support assembly 300 more stably, connecting strips can be disposed on two opposite sides of the flexible screen 100 along the second direction, and the connecting strips extend to the ends of the sides of the flexible screen 100, so that when the connecting strips are connected with the support assembly 300, the corresponding sides of the flexible screen 100 can be deformed in the second direction as a whole by the connecting strips during the relative movement of the first support portion 310 and the second support portion 320 in the support assembly 300.

Accordingly, in order to prevent the frame assembly 200 from interfering with the deformation process of the part of the structure of the flexible screen 100 received therein in the second direction, the frame assembly 200 may be made to have a penetrating structure in the second direction, so that it is ensured that the part of the flexible screen 100 received in the frame assembly 200 can be protruded from the frame assembly 200 and deformed accordingly when receiving the tensile force in the second direction.

In addition, in order to make the electronic device have a stronger usability, in the embodiment of the present application, no matter how the frame assembly 200 and the support assembly 300 move relatively along the first direction, the portion of the flexible screen 100 supported on the support assembly 300 is always exposed outside the electronic device, so that when a user needs to use the electronic device to view some text or voice information, the user does not need to perform any operation on the frame assembly 200 and the support assembly 300, which can improve the usability of the electronic device; under the conditions that the user has the requirements of mobile office, drawing a drawing, watching a video file and the like, the display area of the electronic equipment can be enlarged and the user experience can be improved by enabling the frame assembly 200 and the supporting assembly 300 to perform corresponding actions.

In the above-described embodiment, the positional relationship between the frame assembly 200 and the support assembly 300 in the electronic apparatus may be changed in the first direction by a manual manner, thereby changing the overall size of the electronic apparatus. Optionally, in the embodiment of the present application, the electronic device may further include a driving assembly 400, where the electronic device is provided with the driving assembly 400, the driving assembly 400 may be used to drive the structures of the support assembly 300 and the flexible screen 100, and the relative positional relationship between the frame assembly 200 and the support assembly 300 in the electronic device may be directly or indirectly changed by using the driving assembly 400, so as to maximize the automation degree of the electronic device.

In detail, the driving assembly 400 may be mounted on the first supporting portion 310, and the driving assembly 400 is further connected to both the second supporting portion 320 and the frame assembly 200, so that the driving assembly 400 drives the first supporting portion 310 and the second supporting portion 320 to move relatively in the second direction, and simultaneously drives the frame assembly 200 and the supporting assembly 300 to move relatively in the first direction, thereby ensuring that the housing of the electronic device can deform in the first direction and simultaneously deform in the second direction.

Alternatively, the drive assembly 400 is a linear drive device, e.g., the drive assembly 400 may be a linear motor, a pneumatic cylinder, a hydraulic cylinder, or the like. Meanwhile, by making the driving direction of the driving assembly 400 parallel to the first direction or the second direction, the driving assembly 400 may provide the driving force in the first direction or the second direction.

Alternatively, in the case that the number of the driving assemblies 400 is one, the driving direction of the driving assemblies may be located in a plane where the first direction and the second direction are located, and the driving direction may be disposed obliquely with respect to both the first direction and the second direction, so that the driving assemblies 400 may provide a linear driving effect oblique with respect to both the first direction and the second direction, and under the force decomposition, the driving assemblies 400 may drive both the frame assembly 200 and the first supporting portion 310 to move relatively in the first direction and the first supporting portion 310 and the second supporting portion 320 to move relatively in the second direction.

In the case that the driving assemblies 400 are linear driving devices, the number of driving assemblies 400 may be further increased, and by making the driving direction of at least one driving assembly 400 parallel to the first direction and making both the frame assembly 200 and the first supporting portion 310 connected to the driving assembly 400, the driving assembly 400 may be used to drive the first supporting portion 310 and the frame assembly 200 to move relatively in the first direction; meanwhile, by making the driving direction of at least one other driving assembly 400 parallel to the second direction and connecting both the first supporting portion 310 and the second supporting portion 320 to the driving assembly 400, the driving set can drive the first supporting portion 310 and the second supporting portion 320 to move relatively in the second direction.

In order to improve the motion synchronism and reduce the control difficulty of the driving assembly 400, the electronic device disclosed in the embodiment of the application may further include a reversing assembly 500, so as to provide a transmission effect for the driving assembly 400 by using the reversing assembly 500, and change the driving effect direction, so as to ensure that the driving assembly 400 can provide a driving effect for a corresponding structure through the reversing assembly 500.

Based on this, in the process of assembling the electronic device disclosed in the embodiment of the present application, the driving assembly 400 may be mounted on the first supporting portion 310, and one of the second supporting portion 320 and the frame assembly 200 is connected to the driving assembly 400, and the other is connected to the driving assembly 400 through the reversing assembly 500, so that when the driving assembly 400 drives the first supporting portion 310 and the second supporting portion 320 to relatively move along the second direction, the first supporting portion and the frame assembly are driven to relatively move along the first direction together, so that the electronic device is switched between the unfolded state and the folded state, and the automation degree of the electronic device is relatively higher.

In the case of the embodiment of the present application, the driving direction of the driving assembly 400 may be a first direction or a second direction, and taking the driving action direction of the driving assembly 400 as the first direction as an example, the reversing assembly 500 is used to convert the driving action of the first direction provided by the driving assembly 400 into the transmission driving force along the second direction.

As described above, the driving unit 400 may be a linear driving member, for example, taking the driving force provided by the driving unit 400 as the second direction, the driving unit 400 may be mounted on the first supporting portion 310, and by fixedly connecting the driving shaft of the driving unit 400 with the second supporting portion 320, the first supporting portion 310 and the second supporting portion 320 may be moved in the second direction or in opposite directions when the driving unit 400 is operated.

Specifically, the reversing assembly 500 may include a plurality of components, for example, the reversing assembly 500 may include a fixed pulley, a cable, and an elastic restoring member, where the driving end of the driving assembly 400 may be connected to the frame assembly 200 by the cable passing around the fixed pulley in the case where the driving assembly 400 is mounted on the first supporting portion 310, and the elastic restoring member is elastically connected between the first supporting portion 310 and the frame assembly 200. The driving assembly 400 may provide a tensile force to the frame assembly 200 through the cable, so that the frame assembly 200 moves in a direction approaching to the first supporting portion 310, to reduce the size of the portion of the flexible screen 100 exposed in the first direction, and at the same time, under the action of the driving force of the driving assembly 400, the elastic restoring member may be pressed, and then under the action of the elastic restoring member, the driving assembly 400 may release the cable, so as to drive the first supporting portion 310 and the frame assembly 200 to move back to back in the first direction, to increase the size of the portion of the flexible screen 100 exposed in the second direction.

In addition, by changing the specific connection position of the elastic restoring member, the elastic restoring member may be stretched during the process of the driving assembly 400 driving the first support portion 310 and the second support portion 320 to move towards each other, and the elastic restoring member may be used to move the first support portion 310 and the frame assembly 200 away from each other when the driving assembly 400 drives the first support portion 310 and the second support portion 320 to move away from each other.

An embodiment of the application discloses an electronic device comprising a flexible screen 100. The frame assembly 200, the support assembly 300, the driving assembly 400 and the reversing assembly 500, the flexible screen 100 has a stretchable capability, and the flexible screen 100 is connected to the support assembly 300, so that the dimension of the flexible screen 100 in the second direction can be changed during the relative movement of the first support portion 310 and the second support portion 320 in the support assembly 300 in the second direction; a portion of the flexible screen 100 can be received within the frame assembly 200 with the electronic device in a collapsed state. Meanwhile, the frame assembly 200 is movably coupled with the first support 310 in the first direction, so that the flexible screen 100 can be switched between the unfolded state and the folded state, and the size of the display portion of the flexible screen exposed outside the frame assembly 200 can be changed in the first direction.

In addition, in the electronic device, one of the second supporting portion 320 and the frame assembly 200 is connected with the driving assembly 400, and the other is connected with the driving assembly 400 through the reversing assembly 500, so that the driving assembly 400 can provide driving force along the first direction and the second direction together, and further, under the condition that the first supporting portion 310 and the second supporting portion 320 are driven to move relatively along the second direction, the first supporting portion 310 and the frame assembly 200 are driven to move relatively along the first direction together, so that the electronic device is driven to be switched between an unfolding state and a folding state automatically, and the size of a part of the flexible screen 100 exposed out of the frame assembly 200 can be changed in the first direction or the second direction, so that the electronic device can ensure that the flexible screen 100 is relatively consistent in any state while having a larger display area and stronger portability, and the software adaptation performance of the flexible screen 100 is improved, and the user experience is further improved.

Considering that the flexible screen 100 is connected to the support assembly 300, the driving direction of the driving assembly 400 may be the second direction, in which case, the driving force of the driving assembly 400 may directly act on different portions of the support assembly 300, so as to provide a stronger and more stable driving effect for the stretching process of the flexible screen 100, and ensure that the flexible screen 100 can be reliably deformed. Based on this, the driving force between the frame assembly 200 and the first support 310 can be transmitted as an intermediate member using the reversing assembly 500.

In another embodiment of the present application, the reversing assembly 500 may further include a plurality of links, and specifically may include a first link 510 and a second link 520 that are rotatably connected, so as to form a "hard" connection between the components connected by the reversing assembly 500, so as to ensure that the driving assembly 400 can apply a tensile force and a pushing force to both the corresponding components. In this case, the structural composition of the reversing assembly 500 is relatively simple, and the control difficulty of the whole reversing assembly 500 is relatively low, so that the structural stability and reliability of the reversing assembly 500 can be improved.

For convenience of description of a specific assembly form of the reversing assembly 500, taking the driving assembly 400 mounted on the first support portion 310 and the reversing assembly 500 including the first link 510 and the second link 520 as an example, a first end of the first link 510 is hinged to the driving assembly 400, a first end of the second link 520 is hinged to the first support portion 310, and a second end of the first link 510 is hinged to a second end of the second link 520, so that when the driving assembly 400 provides a driving force in a second direction, the first link 510 and the second link 520 which are rotatably connected can rotate relatively with respect to each other with a hinge point therebetween as a reference point, thereby changing a distance between the first end and the second end of the first link 510 in the first direction, and realizing conversion of the driving force of the driving assembly 400 in the second direction into the force in the first direction.

Also, the second ends of the first link 510 and the second link 520 (i.e., the hinge ends thereof) may be hinged at corresponding positions on the frame assembly 200 by means of pins 540 or the like, thereby enabling the first link 510 and the second link 520 to transmit the driving force of the driving assembly 400 to the frame assembly 200.

In order to reduce the space occupied by the movement of the first and second links 510 and 520, alternatively, the hinge ends of the first and second links 510 and 520 may be connected to the frame assembly 200 through the connection rod 530. Meanwhile, the assembly relationship between the connection rod 530 and the frame assembly 200 may be determined according to specific parameters of the first and second connection rods 510 and 520.

Specifically, if the hinge ends of the first and second links 510 and 520 are displaced in the first direction when the first and second links 510 and 520 are subjected to a force in the second direction, the connection rod 530 and the frame assembly 200 may be in a relatively fixed relationship; accordingly, if the hinge ends of the first link 510 and the second link 520 are displaced in the second direction in addition to the first direction when the force is applied thereto, the connection rod 530 and the frame assembly 200 may be relatively fixed in the first direction and relatively movable in the second direction.

In a specific embodiment, the first link 510 and the second link 520 have equal lengths, the respective first ends of the two links are hinged, the respective second ends of the first link 510 and the second link 520 are hinged to the driving assembly 400 and the frame assembly 200 (or the aforementioned connecting rod 530), respectively, and a line between the respective first ends of the first link 510 and the second link 520 is parallel to the second direction. In the case of the above-described technical solution, when the first link 510 and the second link 520 receive the force in the second direction, the direction of the force can be converted into the first direction by the relative rotation, thereby ensuring the relative movement between the frame assembly 200 and the first support 310 in the first direction.
