In the disclosed embodiment, there is provided a foldable assembly, as shown in fig. 1 (for illustrating elastic members), which includes a support layer 100, a first support member 200, a second support member 300, and a folding support mechanism, wherein,
one surface of the support layer 100 is provided with a folding area a, and a first support area B and a second support area C located at both sides of the folding area a; the first supporting member 200 is disposed in the first supporting region B, and a first supporting wall 210 is disposed on a side wall of the first supporting member 200 close to the folding region a; the second support 300 is arranged in the second support area C, and a second support wall 310 is arranged on the side wall of the second support 300 close to the folding area a; the folding support mechanism comprises an elastic piece 410 and a limiting wall 430; the limiting wall 430 is arranged in the folding area A and is provided with a first limiting channel; the elastic element 410 is located between the first supporting wall 210 and the second supporting wall 310, and the elastic element 410 is disposed through the first limiting channel; when the foldable assembly is in the folded state, the elastic member 410 is bent and provides a force to make the foldable assembly in the flat state.
When the foldable assembly provided by the present disclosure is folded, the elastic member 410 slides in the first limiting channel to keep the position thereof stable; at the same time, the elastic member 410 will bend and generate an elastic force that can make the foldable module take a flat state. Therefore, when the foldable assembly is converted between the folded state and the flat state, the elastic part 410 only needs to slide relatively in the first limiting channel, the abrasion between the elastic part and the first limiting channel is small, the mechanical abrasion of the foldable assembly is reduced, and the service life of the foldable assembly is prolonged. Moreover, the foldable assembly only needs to restore the flat state by means of the elastic force of the elastic member 410, and does not need to position the flat state or the folded state of the foldable assembly by means of the elastic member 410, and does not need to support other parts of the foldable assembly by means of the elastic member 410, so that the normal function of the foldable assembly is not affected even if the elastic member 410 is worn, and the service life of the foldable assembly is further prolonged. Moreover, when the elastic member 410 of the foldable assembly is damaged, the elastic member 410 can be repaired in a mode of replacing the elastic member 410 without completely replacing the folding supporting mechanism, so that the repairability and the convenience of repair of the foldable assembly are improved.
The components of the foldable module provided by the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings:
as shown in fig. 1, the support layer 100 may be made of a flexible material so as to be able to bend as the foldable assembly is folded. The support layer 100 has two oppositely disposed surfaces, one of which is used for disposing the first support 200, the second support 300 and the folding support mechanism, and the other of which is used for carrying the flexible display panel. For example, in one embodiment, the other side of the support layer 100 may be adhered with a flexible OLED (organic light emitting diode) panel to form a foldable display device.
The shape of the support layer 100 may be circular, rectangular or other shapes, so as to meet the requirements of the foldable display device. In one embodiment, the support layer 100 may have a symmetrical structure, wherein the first support region B and the second support region C are symmetrical about the central axis D of the folding region. As shown in fig. 2 (the support layer, the protective layer, etc. are not shown), the central axis D of the folding region is a connecting line of points in the folding region a that are equidistant from the first support region B and the second support region C; that is, any point on the central axis D of the folding region is located at a distance from the first support region B equal to the distance from the second support region C. Optionally, the folding area a, the first supporting area B, and the second supporting area C are all rectangular areas, an edge of the folding area a coinciding with the first supporting area B is parallel to the central axis D of the folding area, and an edge of the folding area a coinciding with the second supporting area C is parallel to the central axis D of the folding area.
As shown in fig. 1, the first support 200 may be fixed to the first support area B by adhesion, adsorption, or other means. In one embodiment, the first support member 200 may be adhered to the first support region B by an adhesive layer. The first support member 200 may be made of a rigid material, and may be a hollow structure or a solid structure, so as to realize rigid support of the first support region B. The first support wall 210 and the first support member 200 may be an integral structure, or may be fixed to the first support member 200 by screwing, bonding, or the like.
As shown in fig. 1, the second support 300 may be fixed to the second support area C by adhesion, adsorption, or other means. In one embodiment, the second supporting member 300 may be adhered to the second supporting region C by an adhesive layer. The second supporting member 300 may be made of a rigid material, and may be a hollow structure or a solid structure, so as to realize rigid support for the second supporting region C. The second supporting wall 310 and the second supporting member 300 may be an integral structure, or may be fixed to the second supporting member 300 by a screw connection, an adhesive, or the like.
The retaining wall 430 may be secured to the fold area a by a screw connection, an adhesive connection or other connection means. In this manner, when the foldable module is folded, as shown in fig. 4 and 5, the support layer 100 is bent at the folding area a, and the position-limiting wall 430 does not relatively displace with respect to the support layer 100 at an end thereof adjacent to the support layer 100. As such, the position limiting wall 430 can effectively limit the position of the elastic member 410, such that the elastic member 410 can effectively provide elastic force, regardless of whether the foldable assembly is in the folded state or the flat state, or in the transition state between the two states.
In one embodiment, as shown in fig. 3 (for illustrating the pressure-bearing member), the limiting wall 430 may be further provided with a second limiting channel; the folding support mechanism further includes a bearing member 420, the bearing member 420 being located between the first support wall 210 and the second support wall 310; the pressure-bearing piece 420 penetrates through the second limiting channel, and the elastic modulus of the pressure-bearing piece 420 is smaller than that of the elastic piece 410; when the foldable assembly is in a flat state, the bearing member 420 is straightened and two ends of the bearing member 420 respectively abut against the first support wall 210 and the second support wall 310. The pressure bearing member 420 can support the first support wall 210 and the second support wall 310, so that the foldable assembly can be accurately in a flat state, and the unfolding accuracy of the foldable assembly is ensured. Moreover, when the pressure-bearing part 420 of the foldable assembly is damaged, the pressure-bearing part 420 can be repaired in a replacement mode without completely replacing the folding supporting mechanism, so that the repairability and the convenience of repair of the foldable assembly are improved.
The number of the first limiting channels and the number of the second limiting channels can be multiple and the first limiting channels and the second limiting channels are arranged at intervals; correspondingly, the number of the elastic pieces 410 is the same as that of the first limiting channels, and the elastic pieces 410 penetrate through the first limiting channels in a one-to-one correspondence manner; the number of the pressure-bearing pieces 420 is the same as that of the second limiting channels, and the plurality of pressure-bearing pieces 420 penetrate through the plurality of second limiting channels in a one-to-one correspondence manner. Thus, as shown in fig. 8, the number of the elastic members 410 and the pressure-bearing members 420 is multiple and the elastic members 410 and the pressure-bearing members 420 are arranged at intervals, so that the force provided by the elastic members 410 and the pressure-bearing members 420 to the folding support mechanism can be more uniform and balanced, and the folding assembly can be more stably and stably folded or unfolded.
In an embodiment, as shown in fig. 1, 2 and 3, the stopper wall 430 may include a first stopper wall 431 and a second stopper wall 432 disposed side by side; the first stopper wall 431 is located on a side of the second stopper wall 432 adjacent to the first support wall 210, and the second stopper wall 432 is located on a side of the first stopper wall 431 adjacent to the second support wall 310. The first limiting channels of the first limiting wall 431 and the first limiting channels of the second limiting wall 432 are arranged in a one-to-one correspondence manner; any elastic element 410 is arranged in the first limiting channel of the first limiting wall 431 and the first limiting channel of the second limiting wall 432 correspondingly; the second limiting channels of the first limiting wall 431 and the second limiting channels of the second limiting wall 432 are arranged in a one-to-one correspondence manner; any one of the pressure-bearing members 420 is inserted into the second limiting channel of the first limiting wall 431 and the second limiting channel of the second limiting wall 432 which are correspondingly arranged.
As such, as shown in fig. 1, 2 and 3, a gap exists between the first stopper wall 431 and the second stopper wall 432, and the portions of the elastic member 410 and the pressure member 420 between the first stopper wall 431 and the second stopper wall 432 can be freely bent. On the one hand, this ensures that the elastic member 410 can provide the elastic force with the maximum efficiency, so that the foldable module in the folded state can obtain the elastic force sufficient to restore the flat state. On the other hand, the pressure-bearing piece 420 can be ensured to have enough bending space, the problem that the folding capacity of the foldable assembly is reduced due to the fact that the pressure-bearing piece 420 is difficult to bend is avoided, a user can fold the foldable assembly with small force, and the use experience of the user is improved.
When the foldable module is in a flat state, as shown in fig. 1, 2 and 3, the first support wall 210, the second support wall 310, the first stopper wall 431 and the second stopper wall 432 may be parallel to each other. In one embodiment, the first and second limiting walls 431 and 432 extend in a direction parallel to the central axis D of the folding area. Alternatively, the first limiting channel of the first limiting wall 431 and the first limiting channel of the second limiting wall 432 which are correspondingly arranged may be aligned with each other, that is, when the foldable assembly is in a flat state, orthographic projections of the two first limiting channels on the first limiting wall 431 may coincide. Thus, the direction in which the elastic element 410 passes through the two first limiting channels is taken as the extending direction of the elastic element, and the extending direction of the elastic element 410 is perpendicular to the central axis D of the folding region. Alternatively, the correspondingly disposed second limiting channel of the first limiting wall 431 and the second limiting channel of the second limiting wall 432 may be aligned with each other, that is, when the foldable assembly is in a flat state, orthographic projections of the two second limiting channels on the first limiting wall 431 may coincide. Thus, the direction in which the pressure-bearing member 420 passes through the two second limiting passages is taken as the extending direction thereof, and the extending direction of the elastic member 410 is perpendicular to the central axis D of the folding area. This not only facilitates the setting and positioning of the first limiting wall 431 and the second limiting wall 432, but also ensures that the pressure-bearing members 420 at different positions have the same state, and that the elastic members 410 at different positions have the same state, thereby ensuring that the stress states of the folding support mechanism at different positions in the central axis D direction of the folding region are the same.
In one embodiment, as shown in fig. 1, 2 and 3, each of the first and second stopper walls 431 and 432 may be a rectangular long plate (rectangular parallelepiped); when collapsible subassembly is the straight state, the length direction of rectangle long slab is folding region's axis D direction, and the width direction of rectangle long slab is the direction of perpendicular to folding region A, and the width direction of rectangle long slab is the direction of the first support wall 210 of perpendicular to, and the length of rectangle long slab is greater than the width of rectangle long slab, and the width of rectangle long slab is greater than the height of rectangle long slab.
Optionally, the first limiting channels on the first limiting wall 431 and the second limiting wall 432 may be first limiting holes opened on the first limiting wall 431 and the second limiting wall 432, and the cross section of the first limiting hole may match with the cross section of the elastic member 410. This is done. The elastic member 410 can slide in the stopper hole, and can transmit the elastic force during bending to the first support member 200 and the second support member 300 through the first stopper wall 431 and the second stopper wall 432.
Optionally, the second limiting channels on the first limiting wall 431 and the second limiting wall 432 may be second limiting holes opened on the first limiting wall 431 and the second limiting wall 432, and the cross section of the second limiting hole may match with the cross section of the pressure-bearing member 420. This is done. The bearing member 420 can slide in the stopper hole.
The elastic member 410 may be a sheet member, a plate member, a rod member, a wire member or other members made of an elastic material, so as to be capable of being elastically deformed when being bent and providing an elastic force to restore the elastic member 410. The elastic member 410 may be made of an elastic metal material such as beryllium bronze or spring steel; for example, the elastic member 410 may be 65Mn spring steel.
In one embodiment, as shown in fig. 2, the elastic member 410 may include an elastic piece 411 to reduce the thickness of the elastic member 410, and to reduce the elastic force provided by the elastic member 410 when the foldable module is bent, so as to prevent the foldable module from being damaged by excessive elastic force.
Optionally, as shown in fig. 2, the elastic element 410 may further include a first position-limiting portion 412 and a second position-limiting portion 413 disposed at two ends of the elastic sheet 411; the first stopper portion 412 is located between the first support wall 210 and the stopper wall 430, and the second stopper portion 413 is located between the second support wall 310 and the stopper wall 430. When the foldable assembly is folded, the first position-limiting portion 412 and the second position-limiting portion 413 may abut against the side surface of the position-limiting wall 430. Thus, the elastic member 410 can be always effectively constrained by the first limiting channel, so that the elastic member can be always arranged in the first limiting channel in a penetrating manner, and the position of the elastic member 410 is ensured.
It is understood that if the stopper wall 430 includes a first stopper wall 431 and a second stopper wall 432 arranged side by side, the first stopper portion 412 is located between the first stopper wall 431 and the first support wall 210, and the second stopper portion 413 is located between the second stopper wall 432 and the second support wall 310.
Alternatively, as shown in fig. 8, in a cross section perpendicular to the extending direction of the elastic pieces 411, the middle portions of the elastic pieces 411 are bent toward or away from the support layer 100; the bending directions of the two adjacent elastic pieces 411 are opposite. In this way, the uniformity of the elastic force provided by the elastic piece 411 can be further ensured.
The pressure-bearing part 420 can be made of a pressure-resistant material with certain elasticity, so that on one hand, the pressure-bearing part 420 can support the first support wall 210 and the second support wall 310 in a straight state, the foldable assembly is prevented from being folded reversely, and the foldable assembly can be accurately in the straight state; on the other hand, the pressure-bearing piece 420 can be ensured to be bent in a folded state, and the situation that the pressure-bearing piece 420 obstructs the bending of the foldable assembly due to the fact that the pressure-bearing piece has strong bending resistance is avoided. In one embodiment, the pressure bearing member 420 may be made of a rubber material. The shape of the pressure bearing member 420 may be a column, a plate, a bar, or other shapes, which are not particularly limited in this disclosure.
In one embodiment, as shown in fig. 2, the pressure bearing member 420 may include a pressure bearing column 421, and a third stopper 422 and a fourth stopper 423 disposed at both ends of the pressure bearing column 421; the third stopper 422 is located between the first support wall 210 and the stopper wall 430, and the fourth stopper 423 is located between the second support wall 310 and the stopper wall 430; when the foldable assembly is in a folded state, the third position-limiting portion 422 and the fourth position-limiting portion 423 abut against the side surface of the position-limiting wall 430.
Therefore, the pressure-bearing piece 420 can be always effectively constrained by the second limiting channel, so that the pressure-bearing piece can be always arranged in the second limiting channel in a penetrating manner, and the position of the pressure-bearing piece 420 is ensured. It is understood that if the stopper wall 430 may include a first stopper wall 431 and a second stopper wall 432 arranged side by side, the third stopper portion 422 is located between the first stopper wall 431 and the first support wall 210, and the fourth stopper portion 423 is located between the second stopper wall 432 and the second support wall 310.
Alternatively, as shown in fig. 5 and 6, the thicknesses of the third position-limiting portion 422 and the fourth position-limiting portion 423 may gradually increase along the direction away from the support layer 100; the thickness of the third position-limiting part 422 is the dimension of the third position-limiting part 422 along the extending direction of the pressure-bearing pillar 421; the thickness of the fourth stopper portion 423 is a dimension of the fourth stopper portion 423 along the extending direction of the pressure receiving pillar 421.
When the foldable assembly is folded, the pressure-bearing member 420 will bend toward the supporting layer 100, so that the pressure-bearing member 420 deforms more along the portion far from the supporting layer 100, resulting in a larger force between the portion far from the supporting layer 100 of the third position-limiting part 422 and the fourth position-limiting part 423 and the position-limiting wall 430, which is more easily damaged. The thickness of the part of the third limiting part 422 and the fourth limiting part 423 far away from the support layer 100 is increased, the probability of damage of the third limiting part 422 and the fourth limiting part 423 can be reduced, the service life of the foldable component is prolonged, and the service life of the foldable component is prolonged.
Of course, in another embodiment, as shown in fig. 7, in order to simplify the structure of the pressure receiving member 420 and reduce the difficulty of installing the pressure receiving member 420, the thickness of each of the third and fourth position-limiting parts 422 and 423 is the same.
In one embodiment, as shown in fig. 1, the foldable module may further include a protective layer 500, the protective layer 500 covering a side of the folding support mechanism away from the support layer 100. Thus, the folding supporting mechanism can be clamped by the protective layer 500 and the supporting layer 100, thereby preventing the folding supporting mechanism from being exposed and damaged, further prolonging the service life of the foldable component, and improving the appearance of the folding supporting mechanism. Alternatively, the protection layer 500 may be adhered to the surface of the first support 200 away from the support layer 100 and the surface of the second support 300 away from the support layer 100, so as to achieve stable and reliable fixation. Further, one end of the limiting wall 430 away from the supporting layer 100 is bonded to the protective layer 500, so as to further improve the stability of the limiting wall 430.
In an embodiment, as shown in fig. 2 and 8, the foldable assembly may further include two package plates 600, the package plates 600 are respectively disposed at two ends of the folding support mechanism along the central axis direction thereof, and any one of the package plates 600 connects the protection layer 500, the support layer 100, the first support wall 210 and the second support wall 310. Thus, the folding support mechanism can be enclosed inside the foldable assembly by the two package plates 600, the protective layer 500, the support layer 100, the first support wall 210 and the second support wall 310, and isolated from the external environment, so that the risk of damage to the folding support mechanism is further reduced, and the service life of the foldable assembly is prolonged.
In one embodiment, the distance from the support layer 100 of the pressure bearing member 420 may be greater than the distance from the protective layer 500 of the pressure bearing member 420 when the foldable assembly is in the flat state. Therefore, the foldable assembly is not easy to be folded reversely, and the stability of the foldable assembly in a flat state can be further improved.
In an embodiment, the foldable assembly may further include a first connector and a second connector detachably connected, the first connector may be disposed at the first support 200, and the second connector may be disposed at the second support 300. When the foldable assembly is in the folded state, the first connecting piece and the second connecting piece can be mutually matched, so that the foldable assembly is kept in the folded state.
