Detailed Description
Features and exemplary embodiments of various aspects of the present application are described in detail below to make the objects, technical solutions and advantages of the present application more apparent, and to further describe the present application in conjunction with the accompanying drawings and the detailed embodiments. It should be understood that the specific embodiments described herein are intended to be illustrative of the application and are not intended to be limiting. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by showing examples of the present application.
It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element.
The size of the display device is increasing with time, but the larger the display device is, the more inconvenient it is to carry during carrying. With the development of flexible screen technology, flexible display devices capable of being bent are generated, and display devices capable of being wound on wrists are generated, so that the display devices can be used as normal display devices in a flattened mode, can be tightly wound on wrists, cannot fall off easily, and are convenient to carry. The design can not only solve the carrying problem of large-size display equipment, but also meet the use requirements of different scenes.
However, such flexible display devices are prone to problems during bending, and in particular, the flexible display devices generally include a flexible screen and a flexible supporting mechanism, both of which can be bent by themselves, and since the flexible supporting mechanism has a certain thickness, the neutral layers of the flexible supporting mechanism and the flexible screen are not in the same plane, resulting in different bending degrees of the flexible supporting mechanism and the flexible screen, but since the flexible supporting mechanism and the flexible screen are generally fixed together, breakage or crack problems of the flexible screen are prone to occur during bending.
It should be noted that, the neutral layer of the flexible supporting mechanism refers to a plane with a constant length of the flexible supporting mechanism in the bending process, and the neutral layer of the flexible screen refers to a plane with a constant length of the flexible screen in the bending process, and because the thickness of the flexible screen is far smaller than that of the flexible supporting mechanism, the upper/lower surface of the flexible screen can be regarded as the plane where the neutral layer of the flexible screen is located.
In order to solve the above-mentioned problems, please refer to fig. 1 to 4, the embodiment of the present application provides a supporting device for a flexible display device, the supporting device has a first state and a second state, the supporting device is flat in the first state, and the supporting device is bent and deformed in the second state.
The support device comprises a flexible support plate 1, a bending assembly 2 and a sliding connection 3. The flexible support plate 1 has a screen support surface 11, the flexible support plate 1 comprising a first end 12 and a second end 13 arranged opposite along its extension direction X. The screen body supporting surface 11 is used for supporting the flexible screen 4, and ensures the flatness of the flexible screen 4 in normal use. Illustratively, the screen support surface 11 may be a user facing surface of the flexible support plate 1 when the user uses the display device comprising the support means. The first end 12 and the second end 13 are two ends of the flexible support plate 1 in the extending direction X, respectively, and at least one of the first end 12 and the second end 13 can relatively move with respect to the other because the flexible support plate 1 is flexible and bendable.
The bending component 2 is arranged on one side of the flexible supporting plate 1 opposite to the screen body supporting surface 11, and the bending component 2 comprises a bending structure 21 capable of bending and deforming. In a display device comprising a support means, the bending assembly 2 is located on a side of the flexible support plate 1 facing away from the flexible screen 4, the flexible support plate 1 being used to position the flexible screen 4 on the bending assembly 2. The bending structure 21 in the bending assembly 2 can be wound and directly contacted with the wrist, and meanwhile, the flexible support plate 1 drives the flexible screen to bend, so that a user can conveniently carry the display device.
It can be appreciated that the support device provided in the embodiment of the present application can have two states, the flexible support plate 1 and the bending structure 21 in the first state are all straight, and the flexible support plate 1 and the bending structure 21 in the second state are deformed by bending, so that the support device can be wound around the wrist.
The sliding connection piece 3 comprises a sliding piece 31 and a sliding rail 32 which are matched with each other for use, one of the sliding piece 31 and the sliding rail 32 is arranged on the bending structure 21, the other is arranged on the flexible supporting plate 1, the sliding rail 32 extends along the extending direction X of the flexible supporting plate 1, so that when the supporting device is adjusted from a first state to a second state, the sliding piece 31 and the sliding rail 32 are matched with each other to drive at least one of the first end 12 and the second end 13 to move relative to the bending structure 21 along the extending direction X of the flexible supporting plate 1.
The sliding connection member 3 is used for connecting the flexible support plate 1 and the bending structure 21, and includes a sliding rail 32 and a sliding member 31 capable of moving relative to the sliding rail 32. The sliding rail 32 may be an outwardly protruding rail structure or an inwardly recessed sliding groove structure, which is not limited in the embodiment of the present application, so long as the extending direction of the sliding rail 32 is parallel to the extending direction X of the flexible supporting plate 1, and the sliding member 31 may move relative to the extending direction of the sliding rail 32.
The extending direction X of the flexible support plate 1 is determined according to the state of the flexible support plate 1. As shown in fig. 1, when the flexible support plate 1 is in the first state, the extending direction X of the flexible support plate 1 is a straight line direction and is parallel to the length direction of the flexible support plate 1; as shown in fig. 3, when the flexible support plate 1 is in the second state, the extending direction of the flexible support plate 1 is a curved direction and is parallel to the overall extending path of the flexible support plate 1. In addition, since the flexible support plate 1, the flexible screen 4 and the bending member 2 are connected to each other and simultaneously bent or flattened, the extending directions X of the three are substantially the same. The extending direction X mentioned later in this embodiment of the present application may be the extending direction X of any one of the flexible supporting plate 1, the flexible screen 4 and the bending component 2, which is not described in detail in this embodiment of the present application.
The sliding connection piece 3 is respectively arranged on the bending structure 21 and the flexible supporting plate 1, and the specific positions of the sliding connection piece 3 on the bending structure 21 and the flexible supporting plate 1 are not limited. The sliding connection 3 may be disposed on two surfaces of the bending structure 21 opposite to the flexible support plate 1 in the thickness direction, or may be disposed on two sides of the bending structure 21 and the flexible support plate 1 along a second direction Y, wherein the second direction Y is a width direction of the bending structure 21 and the flexible support plate 1.
The movable setting between flexible support plate 1 and the structure 21 is realized through sliding connection 3 to this application embodiment to when display device buckles, flexible screen 4 that is located on strutting arrangement can follow self extending direction X and buckle structure 21 relatively. According to the embodiment of the application, a complex mechanical structure is not needed, the problem that the flexible screen 4 is excessively pulled due to the fact that the bending degree of the flexible screen 4 is different from that of the bending structure 21 can be relieved, and the bending reliability is improved.
As shown in fig. 3 and 4, in some embodiments, the bending assembly 2 further includes a main structure 22, the main structure 22 is disposed on one side of the bending structure 21 along the extending direction X, the first end 12 is fixed to the main structure 22, and the second end 13 is connected to the bending structure 21, so that when the bending structure 21 is bent and deformed, the second end 13 moves along the extending direction X relative to the bending structure 21.
The main body structure 22 is connected with the bending structure 21, and the shape of the main body structure 22 is kept unchanged all the time in the process of changing from the first state to the second state, and the bending structure 21 bends relative to the main body structure 22 and is wound on the wrist of a user. The size of the bending structure 21 of the main body structure 22 is determined according to practical use, and the embodiment of the present application is not limited.
The first end 12 of the flexible support plate 1 is fixed to the main structure 22 and the second end 13 is connectable to the bending structure 21 by means of the sliding connection 3. During the transition from the first state to the second state, the first end 12 is held stationary by the body structure 22 and the second end 13 moves relative to the first end 12 due to the bending of the flexible support plate 1. Meanwhile, since the flexible support plate 1 is not on the same plane with the neutral layer of the bending structure 21, the second end 13 also moves along the extending direction X relative to the bending structure 21 during this process.
In some embodiments, the flexible support plate 1 includes a first portion 14 and a second portion 15, the first portion 14 is located on one side of the main body structure 22, the second portion 15 is located on one side of the bending structure 21, one of the slider 31 and the sliding rail 32 is disposed on the bending structure 21, and the other is disposed on the second portion 15.
The first portion 14 of the flexible support plate 1 is arranged in correspondence with the main structure 22 and the second portion 15 is arranged in correspondence with the bending structure 21, the first end 12 being located in the first portion 14 and the second end 13 being located in the second portion 15. Wherein the first portion 14 does not bend during wear, and the second portion 15 bends and deforms during wear along with the bending of the bending structure 21. Since the relative position of the first portion 14 and the main body structure 22 is kept unchanged all the time, the first portion 14 and the fixing structure do not need to be connected by using the sliding connection piece 3, and can be fixed by welding or bonding.
In this embodiment, the flexible supporting plate 1 includes a first portion 14 and a second portion 15, the flexible supporting plate 1 is fixedly connected with the main structure 22 through the first portion 14, the second portion 15 and the bending structure 21 are not completely attached and fixed, and the two are in sliding connection through the sliding connector 3. The arrangement of the first portion 14 and the main structure 22 can improve the connection reliability between the flexible support plate 1 and the bending assembly 2, and reduce the risk of detachment of the flexible support plate 1 from the bending assembly 2.
Referring to fig. 3 and fig. 5 together, in some embodiments, the sliding member 31 is formed by extending along a second direction Y, and the flexible supporting plate 1 is movably disposed relative to the bending structure 21 in the second direction Y, and the second direction Y intersects with the extending direction X. The second direction Y is the width direction of the flexible support plate 1, optionally perpendicular to the extension direction X when the support device is flat.
As can be seen from the foregoing, the slider 31 may be provided on the flexible support plate 1 or on the bending structure 21. As shown in fig. 5, the present embodiment is described taking an example in which the sliding members 31 are provided on both sides of the flexible support plate 1 in the second direction Y, and are protruded and extended in a direction away from the flexible support plate 1.
In the process of the support device moving from the first state to the second state, the flexible support plate 1 and the bending structure 21 are easy to move relatively in the second direction Y in addition to bending in the extending direction X. Therefore, the embodiment of the application prevents the flexible support plate 1 or the flexible screen from excessively extruding with the bending structure 21 in the width direction in the bending process of the bending structure 21 by allowing the flexible support plate 1 and the bending structure 21 to have a certain offset in the second direction Y, so that the risk of damage to the flexible screen is reduced, and the service life of a product is prolonged.
Referring to fig. 6 and 7, in some embodiments, the sliding member 31 includes a connecting portion 311 and a rolling portion 312, and the rolling portion 312 is connected to one of the bending structure 21 and the flexible supporting plate 1 through the connecting portion 311; the rolling portion 312 is located in the sliding rail 32 and is rotatably connected to the connecting portion 311.
It can be appreciated that when the slider 31 is attached to the flexible support plate 1, the rolling portion 312 is attached to the flexible support plate 1 through the attachment portion 311; when the slider 31 is connected to the bending structure 21, the rolling portion 312 is connected to the bending structure 21 through the connecting portion 311.
The sliding member 31 enters the sliding rail 32 through the rolling portion 312, and the rolling portion 312 can rotate in the sliding rail 32 relative to the inner wall of the sliding rail 32, so that friction resistance between the sliding member 31 and the sliding rail 32 can be reduced in the process of moving the sliding member 31 relative to the sliding rail 32, and the sliding member 31 can move smoothly in the sliding rail 32.
Referring to fig. 3 and 6, in some embodiments, the supporting device further includes a buffer member 5 extending along the second direction Y, and the sliding member 31 is disposed on one of the bending structure 21 and the flexible supporting plate through the buffer member 5.
When the bending structure 21 and the flexible supporting plate 1 move relatively in the second direction Y, the buffer member 5 is disposed at one end of the sliding member 31, so that the buffer member 5 can play a role in buffering, and the positional relationship between the flexible supporting plate 1 and the bending structure 21 in the second direction Y can be adjusted. Specifically, in the process that the supporting device is changed from the first state to the second state, the bending structure 21 drives the flexible supporting plate 1 to bend, in this process, the flexible supporting plate 1 is easy to shift relative to the bending structure 21 in the second direction Y, at this time, the sliding member 31 relatively moves along the second direction Y and presses the buffer member 5, and the existence of the buffer member 5 can avoid one of the flexible supporting plate 1 and the bending structure 21 from directly contacting with the sliding member 31, and meanwhile avoid excessive pressing phenomenon. The cushioning member 5 includes, but is not limited to, an elastic structure such as a spring.
Referring to fig. 3 and 6, in some embodiments, one end of the buffer member 5 is connected to the flexible supporting plate 1, and the other end is connected to the sliding member 31, so that the flexible supporting plate 1 and the bending structure 21 are buffered by the buffer member 5.
The buffer member 5 is disposed between the flexible support plate 1 and the sliding member 31, so as to avoid direct contact between the sliding member 31 and the flexible support plate 1, and further realize a buffering effect on the flexible support plate 1 and the bending structure 21 in the second direction Y, thereby improving reliability of the support device.
In some embodiments, the sliding rail 32 is disposed on the bending structure 21, and the sliding member 31 is disposed on the flexible supporting plate 1.
As shown in fig. 3, the sliding member 31 may be located at an edge of the flexible support plate 1 along the second direction Y and extend outward, and the sliding rail 32 may be disposed at an edge of the bending structure 21 and toward the flexible support plate 1. This design is advantageous in that when a problem occurs in the sliding member 31 or the sliding rail 32, the sliding member 31 and the sliding rail 32 are maintained in time, and the service life of the product is prolonged.
With continued reference to fig. 3 and 6, in some embodiments, the flexible support plate 1 includes a mounting slot 16, the mounting slot 16 is located at an edge of the flexible support plate 1 in the second direction Y and is recessed inward along the second direction Y, and the slider 31 is movably disposed in the mounting slot 16 along the second direction Y.
The embodiment of the application can realize the adjustment of the relative positions of the bending structure and the flexible supporting plate in the second direction Y by changing the specific positions of the sliding parts 31 in the mounting grooves 16. Alternatively, the buffer member 5 may be disposed in the mounting groove 16, and one end of the buffer member 5 abuts against the flexible support plate 1, and the other end abuts against the slider 31. So that the cushion member 5 can reduce the magnitude of the pressing force to the flexible support plate 1 due to the movement of the slider 31 in the second direction Y, in addition to preventing the slider 31 from directly contacting the flexible support plate 1.
Referring to fig. 3 and 7, in some embodiments, the bending structure 21 includes a body portion 211 and protrusions 212 located at two sides of the body portion 211 in the second direction Y and protruding toward the flexible support plate 1, and the flexible support plate 1 is located between the two protrusions 212.
The body portion 211 corresponds the setting with the one side that flexible supporting plate 1 deviates from screen body holding surface 11, and bellying 212 is provided with two and sets up respectively in the both sides of body portion 211 along second direction Y, and the setting of bellying 212 can restrict the maximum offset of flexible supporting plate 1 in second direction Y, avoids flexible supporting plate 1 to take place to break away from along second direction Y with buckling structure 21, improves both connection reliability.
It can be appreciated that when the sliding member 31 is formed by extending along the second direction Y and is movably disposed along the second direction Y, the protrusion 212 can prevent the sliding member 31 from being excessively shifted in the second direction Y, and the sliding member 31 can prevent the flexible supporting plate 1 from directly contacting the protrusion 212, thereby avoiding friction therebetween and prolonging the service life of the supporting device.
Referring to fig. 6 and 7, in some embodiments, the protruding portion 212 has a first surface 2121 facing the body 211, and the sliding rail 32 is disposed on the first surface 2121 and is recessed inward along the second direction Y.
The first surface 2121 is located on one surface of the protruding portion 212 along the second direction Y, and the sliding rail 32 in the embodiment of the present application adopts a sliding groove structure and is formed by recessing the first surface 2121 inward. The sliding member 31 can partially enter the sliding rail 32 along the second direction Y and can move along the extending direction X relative to the sliding rail 32, wherein the sliding distance of the sliding member 31 relative to the sliding rail 32 is determined by the extending length of the sliding rail 32.
Referring to fig. 8 and 9, in some embodiments, the bending structure 21 includes a plurality of links 213 disposed side by side along the extending direction X, two adjacent links 213 are rotatably connected by a rotating portion 214, and at least some links 213 are provided with a sliding rail 32.
The plurality of links 213 are connected by the rotating portion 214, and the size and number of the links 213 are determined according to the size of the flexible support plate, that is, the size of the flexible screen. Wherein, adopt detachable connection between chain link 213 and the rotation portion 214, when the local position of buckling structure 21 goes wrong, can guarantee strutting arrangement's continuation use through changing chain link 213 and rotation portion 214.
As shown in fig. 10, the number of the slide rails 32 may be plural, the number of the slide rails 32 being opposite to the number of the sliders 31, and the plural sliders 31 being capable of dividing the flexible support plate 1 into a plurality of sub-areas. In the wearing process, each sliding piece 31 can drive the corresponding sub-region to move relative to the bending structure 21 along the extending direction, and the design can realize fine adjustment on the moving process of the flexible supporting plate 1, so that the movement of each sub-region on the flexible supporting plate 1 tends to be consistent.
In some embodiments, as shown in fig. 10, the sliding rails 32 are arranged in a one-to-one correspondence with the links 213. The number of the sliding rails 32 is consistent with that of the chain links 213, so that the plurality of sub-areas of the flexible supporting plate 1 divided by the plurality of sliding pieces 31 can correspond to the positions of the chain links 213, and the design can realize accurate adjustment of the relative sliding distance between each sub-area and the corresponding chain link 213, thereby ensuring that the deformation amount of each part of the flexible supporting plate 1 is substantially consistent, and improving the bending reliability of the supporting device.
As shown in fig. 1 and 10, in some embodiments, the sliding tracks 32 on adjacent links 213 are successively rounded.
As can be seen from the foregoing, the first state is the state of the supporting device in normal use, and the flexible supporting plate 1 and the bending structure 21 are both flat structures; the second state is the state of the support device when worn, and at this time, the flexible support plate 1 and the bending structure 21 are bent and deformed, and can be wound on the wrist for convenient carrying.
The bending structure 21 of the present embodiment is composed of a plurality of links 213, and in the second state, in order to enable the support device to conform more to the wrist, the links 213 are generally smaller in size and the amount of deflection between adjacent links 213 is smaller. It can be appreciated that, in order to make the flexible support plate 1 stably bend when bending, the embodiment of the present application sets the plurality of sliding rails 32 to be sequentially and smoothly transited, so as to avoid the problem that the curvature of the flexible support plate 1 is suddenly changed at the corresponding position of the rotating portion 214, and further improve the service life of the display device and the display effect of the display device that is finally formed.
Referring to fig. 11, in some embodiments, the rotation portion 214 is disposed at a first predetermined distance a from the flexible support plate 1 in the thickness direction of the flexible support plate 1.
The bending structure 21 is turned by the adjacent links 213 with respect to the turning part 214, so that the neutral layer of the bending structure 21 is generally the plane of the turning part 214, and as can be seen from the foregoing, in a display device comprising a support means, the neutral layer of the flexible screen can be considered to be on the upper/lower surface of the support plate, i.e. the screen support surface or the surface opposite to the screen support surface, due to the smaller thickness of the flexible screen and the flexible support plate 1.
According to the embodiment of the application, the distance between the rotating part 214 and the flexible support plate 1 in the thickness direction is adjusted, so that the control of the distance between the neutral layer of the bending structure 21 and the neutral layer of the flexible screen is realized, and the control of the relative sliding quantity of the flexible screen and the bending structure 21 in the extending direction is further realized. Optionally, the first preset distance A is in a range of 0.5 mm.ltoreq.A.ltoreq.1 mm.
