[0058] The present disclosure provides a support structure. Figures 1 to 5 As shown, the support structure may include a bearing plate 1, a support assembly, a connecting shaft 3 and a connecting assembly, wherein:

[0059] The carrier plate 1 is used to carry the folding screen. The support assembly includes two support members 2, and the two support members 2 are rotatably connected to the surface of the carrier plate 1 facing away from the folding screen. The connecting shaft 3 is located between the two support members 2, and the rotation axes of the two support members 2 are arranged parallel to the connecting shaft 3 and are both parallel to the carrier plate 1. The connecting assembly includes two connecting members 4, and the two connecting members 4 are rotatably connected to the two support members 2 in a one-to-one correspondence, and are both rotatably connected to the connecting shaft 3. Among them, if Figure 3 As shown, when the connecting shaft 3 is located at the first position, the ends of the two connecting members 4 away from the connecting shaft 3 are both located on the side of the connecting shaft 3 away from the bearing plate 1 in the direction perpendicular to the bearing plate 1, and the angle between the two connecting members 4 is maintained at the first angle, and the two supporting members 2 are both inclined toward the connecting shaft 3; Figure 4 As shown, when the connecting shaft 3 moves from the first position to the second position in a direction away from the bearing plate 1 , the angle between the two connecting members 4 is maintained at the second angle, and the two supporting members 2 are arranged opposite to each other to support the bearing plate 1 .

[0060] In the support structure of the embodiment of the present disclosure, when the connecting shaft 3 is in the first position, the angle between the two connecting members 4 is maintained at the first angle, and the two supporting members 2 are both inclined toward the connecting shaft 3, so that the supporting structure is in a retracted state; when the connecting shaft 3 moves from the first position to the second position in a direction away from the supporting plate 1, the angle between the two connecting members 4 is maintained at the second angle, and the two supporting members 2 are arranged relative to each other to support the supporting plate 1, and the folding screen can be supported by the supporting plate 1.

[0061] The following is a detailed description of each part of the support structure of the embodiment of the present disclosure:

[0062] like Figure 1 and Figure 2 As shown, the carrier plate 1 is used to carry a folding screen. The carrier plate 1 may include a first surface and a second surface opposite to each other. The first surface is used to carry a folding screen. Furthermore, two spaced protrusions 6 may be provided on the first surface of the carrier plate 1, and the folding screen may be located between the two protrusions 6. The two protrusions 6 may be distributed along the axial direction of the above-mentioned connecting shaft 3. The carrier plate 1 may be in a strip-shaped structure and may extend along the axial direction of the connecting shaft 3. The two protrusions 6 may be provided one-to-one at both ends of the carrier plate 1 in the axial direction of the connecting shaft 3. The carrier plate 1 may be provided with fixed shafts 5 on both sides of a preset direction. The preset direction may be parallel to the carrier plate 1 and perpendicular to the above-mentioned connecting shaft 3. Among them, the number of fixed shafts 5 provided on either side of the carrier plate 1 may be two, and the two fixed shafts 5 are coaxially arranged and parallel to the connecting shaft 3.

[0063] like Figure 1 , Figure 2 as well as Figure 7 As shown, the support assembly is used to support the carrier plate 1. The support assembly may include two support members 2. Both support members 2 are rotatably connected to the surface of the carrier plate 1 facing away from the folding screen, that is, the two support members 2 are connected to the above-mentioned second surface. The rotation axes of the two support members 2 may be parallel and parallel to the carrier plate 1. The two support members 2 may be connected to both sides of the carrier plate 1 in a preset direction in a one-to-one correspondence. Taking the case where both sides of the carrier plate 1 in the preset direction are provided with fixed shafts 5 as an example, one support member 2 may be rotatably connected to the fixed shaft 5 on one side of the carrier plate 1, and the other support member 2 may be rotatably connected to the fixed shaft 5 on the other side of the carrier plate 1. Each support member 2 may be in a strip-shaped structure and may extend along the axial direction of the connecting shaft 3. Taking the case where the number of fixed shafts 5 provided on either side of the carrier plate 1 is two as an example, the two ends of each support member 2 in the extension direction may be rotatably connected to the carrier plate 1 through the fixed shaft 5.

[0064] like Figure 4 , Figure 5 , Figure 6 as well as Fig.12As shown, the connecting shaft 3 is located on the side of the supporting plate 1 facing away from the folding screen, and is located between the two support members 2. The connecting shaft 3 is arranged parallel to the rotation axis of the above-mentioned two support members 2. The connecting shaft 3 can be located at the midline position of the two support members 2. The outer peripheral surface of the connecting shaft 3 can be provided with a first limit member 301 and a second limit member 302. The first limit member 301 and the second limit member 302 are spaced apart along the axial direction of the connecting shaft 3. The first limit member 301 can be an annular boss. The second limit member 302 can be a retaining spring. The outer peripheral surface of the connecting shaft 3 can be provided with a retaining groove 303 that cooperates with the retaining spring.

[0065] like Figure 3 and Figure 4 As shown, the connection assembly is used to connect the support member 2 and the connecting shaft 3. The connection assembly may include two connecting members 4. The two connecting members 4 are rotatably connected to the two support members 2 in a one-to-one correspondence, and are both rotatably connected to the connecting shaft 3. Wherein, the connecting member 4 may be connected to one end of the support member 2 away from the load-bearing plate 1. When the connecting shaft 3 is in the first position, the ends of the two connecting members 4 away from the connecting shaft 3 are both located on the side of the connecting shaft 3 away from the load-bearing plate 1 in the direction perpendicular to the load-bearing plate 1, that is, the ends of the two connecting members 4 connected to the support member 2 are both located on the side of the connecting shaft 3 away from the load-bearing plate 1, and the angle between the two connecting members 4 remains at the first angle, and the two support members 2 are both inclined toward the connecting shaft 3. When the connecting shaft 3 moves from the first position to the second position in the direction away from the load-bearing plate 1, the angle between the two connecting members 4 remains at the second angle, and the two support members 2 are arranged relative to each other to support the load-bearing plate 1. Wherein, the second angle is greater than the first angle. The second angle may be 180°, but the embodiments of the present disclosure do not specifically limit this. When the connecting shaft 3 moves from the first position to the second position, the two supporting members 2 inclined toward the connecting shaft 3 can rotate in a direction away from the connecting shaft 3. The two connecting members 4 can both be plate-shaped structures, but the embodiments of the present disclosure are not limited thereto.

[0066] like Figure 1 and Figure 2 As shown, the number of the above-mentioned connecting shafts 3 and the above-mentioned connecting components can be two. The two connecting shafts 3 are coaxially arranged and spaced along the axial direction of the connecting shafts 3. The two connecting shafts 3 correspond to the two connecting components one by one. The two connecting members 4 in each connecting component are rotatably connected to the corresponding connecting shafts 3. Taking the above-mentioned support member 2 as an example of a strip-shaped structure, both ends of each support member 2 in the axial direction of the connecting shaft 3 are rotatably connected to a connecting member 4. Taking the above-mentioned bearing plate 1 as an example of a strip-shaped structure, in the axial direction of the connecting shaft 3, one end of any connecting shaft 3 away from the other connecting shaft 3 can extend out of the bearing plate 1.

[0067] like Figures 3 to 5 as well as Fig.10As shown, the two connecting members 4 may include a first connecting member 401 and a second connecting member 402. In the axial direction of the connecting shaft 3, a telescopic member is provided on the side of the first connecting member 401 facing the second connecting member 402, and a recessed portion 4051 is provided on the side of the second connecting member 402 facing the first connecting member 401. When the connecting shaft 3 is located at one of the first position and the second position, the telescopic member extends into the recessed portion 4051, so that the angle between the two connecting members 4 is maintained at the first angle; when the connecting shaft 3 is located at the other of the first position and the second position, the telescopic member escapes from the recessed portion 4051 and abuts against the second connecting member 402, so that the angle between the two connecting members 4 is maintained at the second angle. For example, when the connecting shaft 3 is located at the first position, the telescopic member extends into the recessed portion 4051; when the connecting shaft 3 is located at the second position, the telescopic member escapes from the recessed portion 4051.

[0068] like Figure 4 , Figure 5 as well as Figures 8 to 12 As shown, the telescopic member may include an elastic member 404 and a first sleeve 403 that can slide in the axial direction of the connecting shaft 3. The elastic member 404 may be a spring. The first connecting member 401 may be provided with a slide groove 4011 extending along the axial direction of the connecting shaft 3 on one side close to the connecting shaft 3, and the first sleeve 403 may be provided with a slider 4032 that slides with the slide groove 4011. The second connecting member 402 may be provided with a second sleeve 405. The first sleeve 403 and the second sleeve 405 may be rotatably sleeved on the connecting shaft 3, and both are located between the first stopper 301 and the second stopper 302. The elastic member 404 abuts between the first stopper 301 and the first sleeve 403. The spring is in a compressed deformation state. The second sleeve 405 abuts between the first sleeve 403 and the second stopper 302. The end surface of the first sleeve 403 facing the second sleeve 405 is provided with a protrusion 4031, and the above-mentioned recessed portion 4051 is provided on the end surface of the second sleeve 405 facing the first sleeve 403. When the connecting shaft 3 is located at one of the first position and the second position, the protrusion 4031 extends into the recessed portion 4051, so that the above-mentioned telescopic member extends into the recessed portion 4051; when the connecting shaft 3 is located at the other position of the first position and the second position, the first sleeve 403 moves toward the first stopper 301, the compression force received by the elastic member 404 increases, the protrusion 4031 escapes from the recessed portion 4051, and the end surface of the second sleeve 405 facing the first sleeve 403 is located outside the recessed portion 4051 and abuts against the protrusion 4031.

[0069] like Fig. 9 and Fig.10As shown, the side of the protrusion 4031 away from the first stopper 301 has a first abutting surface 40311. The end surface of the second sleeve 405 facing the first sleeve 403 is located outside the recessed portion 4051 and has a second abutting surface 4052. The first abutting surface 40311 and the second abutting surface 4052 are both perpendicular to the axial direction of the connecting shaft 3. After the protrusion 4031 is disengaged from the recessed portion 4051, the first abutting surface 40311 can cooperate with the second abutting surface 4052 to increase the squeezing force between the first sleeve 403 and the second sleeve 405, thereby improving the stability of the supporting structure. In addition, the number of the protrusion 4031 and the recessed portion 4051 are both two, and the two protrusions 4031 can extend into the two recessed portions 4051 one by one, and the two protrusions 4031 are distributed along the radial direction of the connecting shaft 3.

[0070] The present disclosure also provides a support device. Fig.13 and Fig.14 As shown, the support device may include a support shaft 10 and a support structure described in any of the above embodiments. The number of the support structures may be multiple, and the multiple support structures are connected in sequence, the connecting shafts 3 of the multiple support structures are parallel to the support shaft 10, and any two adjacent support structures are rotatably connected. The multiple support structures with the connecting shafts 3 located in the first position can be wound around the support shaft 10, and the connecting shafts 3 of the support structures wound around the support shaft 10 are located on the side of the support plate 1 close to the support shaft 10. The support plates 1 of the multiple support structures with the connecting shafts 3 located in the second position are arranged in parallel to jointly carry the folding screen 11.

[0071] During use of the support device of the disclosed embodiment, when the connecting shaft 3 is in the first position, the two support members 2 are inclined toward the connecting shaft 3 so that each support structure is in a storage state, thereby making it convenient to wind a plurality of support structures around the support shaft 10; when the connecting shaft 3 moves from the first position to the second position in a direction away from the supporting plate 1, the angle between the two connecting members 4 is maintained at the second angle, and the two support members 2 are arranged relative to each other so that a plurality of support structures can support the supporting plate 1.

[0072] The following is a detailed description of each part of the supporting device according to the embodiment of the present disclosure:

[0073] like Figure 1 as well as Figures 16 to 18As shown, the support device may further include a coupling 8 to connect two adjacent support structures. The coupling 8 is provided with two axial holes 801 spaced apart, and the axes of the two axial holes 801 may be parallel to the coupling 3. Taking the example that both sides of the bearing plate 1 in a preset direction are connected with fixed shafts 5, for two adjacent support structures, one axial hole 801 of the coupling 8 may be rotatably sleeved on the fixed shaft 5 of one support structure, and the other axial hole 801 may be rotatably sleeved on the fixed shaft 5 of the other support structure, so that the two adjacent support structures are rotatably connected.

[0074] like Fig.14 As shown, for the multiple support structures wound on the support shaft 10, the surfaces of the support members 2 of any two adjacent support structures in the circumferential direction of the support shaft 10 facing away from the connecting shaft 3 cooperate with each other. Taking the case where two adjacent support structures include a first support structure and a second support structure as an example, the surface of the support member 2 of the first support structure close to the second support structure facing away from the connecting shaft 3 cooperates with the surface of the support member 2 of the second support structure close to the first support structure facing away from the connecting shaft 3. In addition, for any two adjacent support structures in the radial direction of the support shaft 10, the surfaces of the two support members 2 of one support structure facing away from the connecting shaft 3 are flush with the surfaces of the two support members 2 of the other support structure facing away from the connecting shaft 3 in a one-to-one correspondence. Among them, there are two surfaces of the two support members 2 of the support structure located in the outer ring facing away from the connecting shaft 3, and there are two surfaces of the two support members 2 of the support structure located in the inner ring facing away from the connecting shaft 3, and the two surfaces located in the outer ring are flush with the two surfaces located in the inner ring in a one-to-one correspondence.

[0075] Among them, Fig.14 As shown, the multiple support structures wound on the support shaft 10 can form multiple support structure groups, each support structure group can include multiple support structures, and the number of support structures in different support structure groups is the same, for example, it can be six, but the present disclosure is not limited to this. Taking the number of support structures in each support structure group as six, the angle between the two end faces of each support structure in each support structure group in the circumferential direction of the support shaft 10 is 30°. The multiple support structure groups can include a first support structure group, a second support structure group, a third support structure group...the (n-1)th support structure group and the nth support structure group connected in sequence, n is greater than or equal to 2. The first support structure group is located at the initial winding position. The size of the multiple support structures in each support structure group is the same, and the size of the support structure in the nth support structure group is greater than the size of the support structure in the (n-1)th support structure group. In the circumferential direction of the support shaft 10, the two end faces of each support structure group are flush, that is, the outer side surfaces of the support members 2 at both ends of each support structure group are flush.

[0076] like Figure 1 , Fig.14 as well as Fig.16As shown, the above-mentioned multiple support structures are used to jointly support the folding screen 11. Taking the case where the surface of the supporting plate 1 facing away from the connecting shaft 3 is provided with the above-mentioned two protrusions 6 as an example, the folding screen 11 supported by the multiple support structures can be located between the two protrusions 6 of each supporting plate 1. When the multiple support structures are wound around the support shaft 10, for any two adjacent support structures in the radial direction of the support shaft 10, the support member 2 of the support structure located on the outer circle overlaps the two protrusions 6 of the support structure located on the inner circle, thereby avoiding the support member 2 from contacting the folding screen 11 between the two protrusions 6, and preventing the folding screen 11 from being damaged.

[0077] like Figures 13 to 15 As shown, the support device may further include a housing 9 and a cylindrical member 12. The support shaft 10 is rotatably connected to the inner wall of the housing 9. The cylindrical member 12 has a first open end and a second open end in the axial direction of the cylindrical member 12. The first open end is connected to the housing 9 and communicates with the inside of the housing 9. Some of the support structures in the plurality of support structures extend into the cylindrical member 12 from the first open end and extend out of the cylindrical member 12 from the second open end. A guide member 13 may be provided on the inner surface of the cylindrical member 12. When the support shaft 10 rotates in one direction of the clockwise direction and the counterclockwise direction, the support structure in the cylindrical member 12 moves toward the first open end, and the guide member 13 guides the connecting shaft 3 to approach the bearing plate 1 so that the connecting shaft 3 moves to the first position; when the support member 2 rotates in the other direction of the clockwise direction and the counterclockwise direction, the support structure in the cylindrical member 12 moves toward the second open end, and the guide member 13 guides the connecting shaft 3 away from the bearing plate 1 so that the connecting shaft 3 moves to the second position.

[0078] Specifically, Fig.15 As shown, the inner surface of the cylindrical member 12 includes a top surface (not shown) and a bottom surface (not shown) that are relatively arranged, and a side surface (not shown) connecting the top surface and the bottom surface. The number of the side surfaces is two, and they are relatively arranged. Among them, the side surface can be perpendicular to the top surface. The guide member 13 includes a guide groove arranged on the side surface. Taking the number of the above-mentioned connecting shafts 3 as one as an example, the guide groove is provided on one side of the cylindrical member 12. Taking the number of the above-mentioned connecting shafts 3 as two as an example, guide grooves are provided on both sides of the cylindrical member 12. The guide groove is inclined relative to the axial direction of the cylindrical member 12; along the direction from the first open end to the second open end, the distance between the guide groove and the top surface gradually increases, that is, the distance between the guide groove and the bottom surface gradually decreases. Among them, the guide groove may include two opposite groove walls, but the embodiments of the present disclosure do not specifically limit this. For the supporting structure located in the cylindrical member 12 , the top surface faces the side of the bearing plate 1 facing away from the connecting shaft 3 and is parallel to the bearing plate 1 . The connecting shaft 3 can slide in the guide groove to move the connecting shaft 3 away from or close to the bearing plate 1 .

[0079] The embodiment of the present disclosure also provides a folding screen device. The folding screen device may include a folding screen and a supporting device described in any of the above embodiments. The folding screen is supported on the supporting plates of each supporting structure. The folding screen may be an organic electroluminescent display screen, but the present disclosure does not limit this. Since the supporting device included in the folding screen device of the embodiment of the present disclosure is the same as the supporting device in the embodiment of the above supporting device, it has the same beneficial effects and will not be repeated here.

[0080] The above is only a preferred embodiment of the present disclosure and does not limit the present disclosure in any form. Although the present disclosure has been disclosed as a preferred embodiment as above, it is not used to limit the present disclosure. Any technician familiar with this profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present disclosure. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present disclosure without departing from the content of the technical solution of the present disclosure are still within the scope of the technical solution of the present disclosure.
