In addition, the second connecting portion 502 of the receiving assembly 500 can drive the second end 112 of the flexible screen 110 to move.
The first connecting portion 401 is driven to move by the telescopic driving assembly 200, and the second connecting portion 502 is driven to move by the accommodating driving assembly 300, so that the distance between the first connecting portion 401 and the second connecting portion 502 can be adjusted, and a preset pulling force can be applied to the flexible screen 110 through the two opposite ends (the first end 111 and the second end 112) of the flexible screen 110, so that the flexible screen 110 is in a tensioned state. When the supporting device 20 is switched between the storage state and the extension state, the telescopic driving assembly 200 and the storage driving assembly 300 may respectively drive the first connecting portion 401 and the second connecting portion 502 to move synchronously (for example, the moving speed of the first connecting portion 401 may be equal to the moving speed of the second connecting portion 502), so that the pulling force applied to the flexible screen 110 is always maintained at the preset pulling force, and thus the influence of the supporting device 20 on the performance of the flexible screen 110 and the display device 10 may be reduced or avoided. In addition, the flexible screen 110 can be kept in a tensioned state through a preset tension force, and the phenomenon that the display effect is influenced due to the fact that the flexible screen 110 is folded when in an extending state is avoided.
For example, the movement of the first connection portion 401 and the second connection portion 502 may be a linear movement or a curvilinear movement. The preset tension may refer to a tension at which the first end 111 and the second end 112 may maintain the tensioned state of the flexible screen 110 and have little or no influence on the performance of the flexible screen 110. In addition, when the flexible screen 110 is in the storage state, the first connecting portion 401 and the second connecting portion 502 can be respectively driven to move by the telescopic driving assembly 200 and the storage driving assembly 300, so that the pulling force applied to the flexible screen 110 is smaller than the preset pulling force, and the influence of the pulling force on the performance of the flexible screen 110 is further relieved.
The telescopic assembly 400 and the telescopic driving assembly 200 provided in the embodiment of the present application will be described below.
Referring to fig. 4, in the telescopic direction C, the telescopic assembly 400 may include a first telescopic end 400a distant from the storage assembly 500 and a second telescopic end 400b close to the storage assembly 500, and the first telescopic end 400a may be provided with a first connection portion 401. Second telescoping end 400b may be connected to housing 130. The first telescopic end 400a moves away from or close to the receiving assembly 500 in the telescopic process of the telescopic assembly 400, so as to drive the first connecting portion 401 to move away from or close to the receiving assembly 500.
Each linkage 410 may include a connection shaft 413, a first link 411, and a second link 412, and the first link 411 and the second link 412 may be rotatably connected by the connection shaft 413. For example, the middle section of the first link 411 and the middle section of the second link 412 are rotatably connected by the connecting shaft 413, so that the distance between the two ends of the first link 411 in the extending direction and the connecting shaft 413 is not greatly different, and the acting force of the connecting shaft 413 applied to the two ends of the first link 411 in the extending direction is balanced. The distance between the two ends of the second link 412 in the extending direction and the connecting shaft 413 is not greatly different, and the acting force of the connecting shaft 413 on the two ends of the second link 412 in the extending direction is balanced.
Referring to fig. 4 and 6, the n linkage sets 410 may include a first linkage set 410a, the first linkage set 410a being located at an end of the telescoping assembly 400 distal from the storage assembly 500, the first linkage set 410a being disposed proximate the first telescoping end 400 a. In the first link group 410a, the ends of the first link 411 and the second link 412 away from the storage assembly 500 may be movably connected to the first connection portion 401. N groupings 410 may also include a second grouping 410b, where second grouping 410b is located at an end of retraction assembly 400 proximate stowing assembly 500, and second grouping 410b is located proximate second retraction end 400 b.
Two adjacent groupings 410 may include a third grouping 410c and a fourth grouping 410d, with the third grouping 410c being located on a side of the fourth grouping 410d away from the stow assembly 500. One end of the first link 411 of the third link 410c close to the stowing assembly 500 is rotatably connected to one end of the second link 412 of the fourth link 410d away from the stowing assembly 500, and one end of the second link 412 of the third link 410c close to the stowing assembly 500 is rotatably connected to one end of the first link 411 of the fourth link 410d away from the stowing assembly 500.
Referring to fig. 4 and 6, in the same linkage 410, a distance between one end A1 of the first link 411 close to the storage assembly 500 and one end B1 of the second link 412 far from the storage assembly 500 is W1, a distance between one end A2 of the second link 412 close to the storage assembly 500 and one end B2 of the first link 411 far from the storage assembly 500 is W2, a distance between A1 and A2 is W3, and a distance between B1 and B2 is W4. When the connecting shaft 413 moves away from the storage assembly 500 in the telescopic direction C, the first link 411 and the second link 412 rotate about the connecting shaft 413, and both W1 and W2 increase, both W3 and W4 decrease, and the extension length of the linkage 410 in the telescopic direction C increases to achieve the extension of the linkage 410. When the connecting shaft 413 moves closer to the storage assembly 500 in the telescopic direction C, the first link 411 and the second link 412 rotate around the connecting shaft 413 in opposite directions, and W1 and W2 are both decreased, W3 and W4 are both increased, and the extension length of the linkage 410 in the telescopic direction C is decreased to achieve the retraction of the linkage 410.
When one of the two adjacent linkages 410 stretches, the other linkage 410 may be driven to stretch, so as to achieve synchronous stretching of the plurality of linkages 410. The telescopic driving assembly 200 may be connected to one of the connecting shafts 413, and the telescopic driving assembly 200 is used to drive the connecting shaft 413 to move in the telescopic direction C, so as to make the telescopic assembly 400 telescopic. The telescopic driving assembly 200 may be connected to any one of the connection shafts 413, and has a large selectivity, which may be suitable for many scenarios. For example, the telescopic driving assembly 200 may be connected to the connecting shaft 413 of the second linkage 410b, so that the driving efficiency of the telescopic driving assembly 200 may be improved.
In the same link group 410, the extension length of the first link 411 and the extension length of the second link 412 may be the same or different. Referring to fig. 4 and 7, the rotation center of the connecting shaft 413 is O. The first connecting rod 411 may include a first extending section 4111 and a second extending section 4112, the first extending section 4111 and the second extending section 4112 are respectively located at two sides of the rotation center O, and the first extending section 4111 is located at one side of the second extending section 4112 away from the receiving assembly 500. For example, the extension lengths of the first extension segment 4111 and the second extension segment 4112 may be the same, so that the forces of the first extension segment 4111 and the second extension segment 4112 on the connection shaft 413 are more balanced. In addition, the second link 412 may include a third extension 4123 and a fourth extension 4124 connected to each other, the third extension 4123 and the fourth extension 4124 are respectively located at two sides of the rotation center O, and the third extension 4123 is located at a side of the fourth extension 4124 far from the receiving assembly 500. For example, the extension lengths of the third extension 4123 and the fourth extension 4124 may be the same, such that the forces of the third extension 4123 and the fourth extension 4124 on the connection shaft 413 are more balanced. In other examples, the first extension segment 4111 and the second extension segment 4112 may have different extension lengths, and the third extension segment 4123 and the fourth extension segment 4124 may have different extension lengths.
In the same grouping 410, the first extension segment 4111 and the third extension segment 4123 may form a first sub-grouping, and the second extension segment 4112 and the fourth extension segment 4124 may form a second sub-grouping. When the first extending section 4111 and the third extending section 4123 rotate around the connecting shaft 413, the first sub-link group expands and contracts. When the second extending segment 4112 and the fourth extending segment 4124 rotate around the connecting shaft 413, the second sub-linkage expands and contracts. And the extension and contraction of the first sub-linkage and the extension and contraction of the second sub-linkage are synchronous. Thus, the speed of retraction of grouping 410 = the speed of retraction of the first sub-grouping + the speed of retraction of the second sub-grouping. The speed of extension of N groupings 410 = N (speed of extension of first sub-grouping + speed of extension of second sub-grouping)
For example, the extension lengths of the first extension segment 4111, the second extension segment 4112, the third extension segment 4123 and the fourth extension segment 4124 may be the same, so that the overall stress on the linkage 410 is uniform, the accommodating volume of the telescopic assembly 400 is small, and at this time, the telescopic speed of the first sub-linkage is the same as the telescopic speed of the second sub-linkage. In the embodiment where the telescopic driving assembly 200 is connected to the connecting shaft 413 of the second linkage 410B, in the second linkage 410B, the moving distance of the connecting shaft 413 is V1 × t, and the moving distance of one end (B1 and B2) of the second linkage 410B far from the storage assembly 500 is V2 × t, where t is the moving time, V1 is the moving speed of the connecting shaft 413 of the second linkage 410B, and V2 is the moving speed of one end of the second linkage 410B far from the storage assembly 500. Since the telescopic speed of the first sub-link group and the telescopic speed of the second sub-link group are the same, V2=2V1 can be derived. The movement speed of one end (corresponding to the first connection portion 401) of the N link groups 410 away from the storage assembly 500 =2n × v1. Therefore, the telescopic driving assembly 200 drives the connecting shaft 413 of the second linkage 410b to move so as to drive the first connecting portion 401 to move, the connecting shaft 413 of the second linkage 410b can be driven to move at a smaller speed, and the first connecting portion 401 can be driven to move at a larger speed, so that the driving efficiency of the telescopic driving assembly 200 can be improved, and energy can be saved. In addition, the telescopic driving assembly 200 is closer to the housing 130, which is advantageous for miniaturization of the display device 10. The conversion relationship between the movement speed of the first connecting portion 401 and the movement speed of the second linkage 410b is simple, which facilitates the synchronous movement of the first connecting portion 401 and the second connecting portion 502.
Referring to fig. 4 and 6, two first sliders 431 are disposed at an end of the first link group 410a away from the receiving assembly 500, one first slider 431 is rotatably connected to the first link 411 of the first link group 410a, and the other first slider 431 is rotatably connected to the second link 412 of the first link group 410 a. The two first sliders 431 are slidably connected to the first connection portion 401 along the extending direction (first direction X) of the first connection portion 401, and the two first sliders 431 are disposed at intervals along the extending direction of the first connection portion 401. During the extension of the telescopic assembly 400, the two first sliders 431 slide toward each other along the extending direction of the first connection portion 401 to approach each other. During the process of accommodating the telescopic assembly 400, the two first sliders 431 slide away from each other along the extending direction of the first connecting portion 401.
One end of the second link group 410b, which is far away from the first link group 410a, is provided with two second sliders 432, one second slider 432 is rotatably connected with the first link 411 of the second link group 410b, and the other second slider 432 is rotatably connected with the second link 412 of the second link group 410 b. The two second sliders 432 may be slidably connected to the housing 130 along the extending direction of the first connecting portion 401, and the two second sliders 432 are spaced apart along the extending direction of the first connecting portion 401. During the extension of the telescopic assembly 400, the two second sliders 432 slide toward each other along the extending direction of the first connection portion 401. During the storage process of the telescopic assembly 400, the two second sliders 432 slide away from each other along the extending direction of the first connecting portion 401.
Referring to fig. 8, the telescopic drive assembly 200 may include a telescopic driving member 230, a first transmission member 210, and a second transmission member 220. The telescopic driving member 230 may be connected to the housing 130, the telescopic driving member 230 may be connected to the second transmission member 220, the telescopic driving member 230 drives the second transmission member 220 to move, and the first transmission member 210 and the second transmission member 220 are linked, so that the second transmission member 220 drives the first transmission member 210 to move. The first transmission member 210 may be connected to the connection shaft 413, and the telescopic driving member 230 sequentially drives the second transmission member 220, the first transmission member 210 and the connection shaft 413 to move, so as to make the telescopic assembly 400 telescopic in the telescopic direction C.
For example, the first transmission member 210 may include a rack extending in the telescopic direction C. The second transmission member 220 may be rotatably connected to the housing 130, and the second transmission member 220 includes a gear (the gear may be a first gear), and the first gear is engaged with the rack. When the first gear rotates, the rack may be driven to move along the telescopic direction C, and the rack drives the connecting shaft 413 to move along the telescopic direction C, so that the telescopic assembly 400 is telescopic along the telescopic direction C. For example, the telescopic driving member 230 may drive the first gear to rotate by means of a belt and a rotating wheel. A first rotating wheel 231 can be arranged on a rotating shaft of the telescopic driving member 230, a second rotating wheel 222 is arranged on the first gear, the axial direction of the first rotating wheel 231 and the axial direction of the second rotating wheel 222 can be arranged in parallel, and the first driving belt 241 is sleeved on the outer sides of the first rotating wheel 231 and the second rotating wheel 222 and is attached to the first rotating wheel 231 and the second rotating wheel 222. The first rotating wheel 231 is driven to rotate by the telescopic driving member 230, the first rotating wheel 231 drives the first driving belt 241 to move, the first driving belt 241 drives the second rotating wheel 222 to rotate, and the second rotating wheel 222 drives the first gear to rotate.

For example, the volume of the fixing member 421 may be larger than the volume of the connecting shaft 413, so that the connection stability between the fixing member 421 and the first transmission member 210 is high, and the connection between the fixing member 421 and the first transmission member 210 and the connecting shaft 413 is easy.
For example, one end of the telescopic sliding rail 422 close to the storage assembly 500 may be connected to the housing 130, one side of the fixing member 421 facing the telescopic sliding rail 422 may be provided with a first matching portion 4211, the first matching portion 4211 has a sliding groove, and the telescopic sliding rail 422 may be inserted into the sliding groove and slide along the sliding groove.

Taking two telescopic sliding rails 422 as an example, two telescopic sliding rails 422 are arranged on the fixing member 421 at intervals, so as to ensure the sliding stability between the fixing member 421 and the telescopic sliding rails 422 through a small number of telescopic sliding rails 422. The two telescopic sliding rails 422 may be located at two opposite ends of the fixing member 421 along the first direction X.
The following describes the storage assembly 500 and the storage driving assembly 300 provided in the embodiment of the present application.

For example, the slider 510 can slide toward or away from the retraction assembly 400 to slide the second end 112 toward or away from the retraction assembly 400. During extension of the retraction assembly 400, the slider 510 slides the second end 112 toward the direction of approaching the retraction assembly 400. During the storage process of the telescopic assembly 400, the sliding member 510 drives the second end 112 to slide in a direction away from the telescopic assembly 400.
For example, the receiving assembly 500 and the retracting assembly 400 may be adjacently arranged along the second direction Y, the sliding direction of the slider 510 may be the second direction Y, and the sliding direction of the slider 510 and the retracting direction C of the retracting assembly 400 may have an included angle, so that the extending direction of the flexible screen 110 may be changed during the extending process of the flexible screen 110, and the display device 10 is prevented from being too elongated when in the extending state.
With reference to fig. 4, the receiving driving assembly 300 may include a receiving driving member 310, a third transmission member 330 and a fourth transmission member 340, wherein the third transmission member 330 and the fourth transmission member 340 are linked, and the fourth transmission member 340 may drive the third transmission member 330 to move. The receiving driving member 310 and the fourth driving member 340 may be connected to the housing 130, and the third driving member 330 may be connected to the sliding member 510. The receiving driving member 310 may be connected to the fourth transmission member 340 to drive the fourth transmission member 340 to move, so that the fourth transmission member 340 drives the third transmission member 330 to move along the sliding direction of the sliding member 510.
For example, referring to fig. 5, the fourth transmission member 340 may include a lead screw 341, the lead screw 341 extends along the sliding direction of the slider 510, the lead screw 341 may be rotatably connected to the housing 130 by a mounting member 342, the number of the mounting members 342 may be at least one, for example, the mounting members 342 may be respectively provided at both ends of the extending direction of the lead screw 341, so that the lead screw 341 is stably connected to the housing 130. The third transmission member 330 may have a through hole, the through hole penetrates through the third transmission member 330 along the sliding direction of the sliding member 510, a wall surface of the through hole has an internal thread, an outer surface of the screw rod 341 has an external thread, the screw rod 341 is inserted into the through hole, and the internal thread of the through hole is engaged with the external thread of the screw rod 341.
The accommodating driving member 310 can drive the screw 341 to rotate, and when the screw 341 rotates, the third transmission member 330 moves along the extending direction of the screw 341 through the matching of the internal thread and the external thread, so as to drive the sliding member 510 to move along the extending direction of the screw 341. For example, the storage driving member 310 may drive the screw 341 to rotate by means of a belt and a rotating wheel, a rotating shaft of the storage driving member 310 is provided with a third rotating wheel 313, the screw 341 is provided with a fourth rotating wheel 344, and the third rotating wheel 313 and the fourth rotating wheel 344 are linked by a second belt 352. Or, accomodate driving piece 310 and can drive lead screw 341 through gear and gear complex mode and rotate, accomodate and be provided with the third gear in driving piece 310's the pivot, be provided with the fourth gear meshing on the lead screw 341, third gear and fourth gear engagement, its principle is similar with flexible drive assembly 200, no longer describes repeatedly.
For example, the receiving assembly 500 may include a receiving rail 520, the receiving rail 520 extends along a sliding direction of the slider 510, and the slider 510 may be slidably connected with the receiving rail 520. For example, the slider 510 may include a second mating portion 512, the second mating portion 512 is located on a side of the second connecting portion 502 facing the bottom wall 132, and the slider 510 is slidably connected to the receiving slide 520 through the second mating portion 512. The second mating portion 512 may have a sliding groove, and the receiving sliding rail 520 may be inserted into the sliding groove and slide along the sliding groove.
For example, the number of the receiving slide rails 520 is at least one, and the number of the receiving slide rails 520 may be 1, 2, 3, 4, or 5 or more. Taking two receiving slide rails 520 as an example, the two receiving slide rails 520 are disposed at intervals along the first direction X at two ends of the slider 510, so that the sliding stability between the slider 510 and the receiving slide rails 520 is ensured by a small number of receiving slide rails 520.
In a second embodiment of the receiving assembly 500 and the receiving driving assembly 300, referring to fig. 9, the receiving assembly 500 may include a winding member 530, and the winding member 530 may have a second connecting portion 502 thereon. The receiving driving assembly 300 (fig. 3) is connected to the winding member 530, and the receiving driving assembly 300 drives the winding member 530 to rotate, so that the flexible screen 110 is wound or unwound on the winding member 530. During extension of retraction assembly 400, flexible screen 110 unwinds from winder 530. During storage of the telescoping assembly 400, the flexible screen 110 is wound around the winding member 530.
In some examples, the winding member 530 may include a reel, and the second connection portion 502 may be located on an outer surface of the reel. The flexible screen 110 is rolled or unwound from a roll during the telescoping process. Since the volume of the reel can be set small, so that the volume of the housing 130 is small, the display device 10 has a small volume when the display device 10 is in the storage state. The storage driving member 310 may drive the reel to rotate by a manner of matching a driving belt with a rotating wheel, or the storage driving member 310 may drive the reel to rotate by a manner of matching a gear with a gear.
In other examples, with continued reference to fig. 9, the winding member 530 may include a first spool 531, a second spool 532, and a drive belt (i.e., a third drive belt 533), the first spool 531 and the second spool 532 being spaced apart, and the axial directions of the first spool 531 and the second spool 532 may be parallel to each other. The third belt 533 is looped around the first and second reels 531, 532 and attached to the first and second reels 531, 532, respectively, and an outer surface of the third belt 533 may have the second connecting portion 502. The storage driving assembly 300 drives at least one of the first reel 531 and the second reel 532 to rotate, so that the third driving belt 533 rotates around the first reel 531 and the second reel 532, thereby driving the second end 112 of the flexible screen 110 to wind or unwind around the winding member 530. Taking the storage driving assembly 300 driving the first reel 531 to rotate as an example, during the extending process of the telescopic assembly 400, the storage driving assembly 300 driving the first reel 531 to rotate along the direction E1; during the storage of the telescopic assembly 400, the storage driving assembly 300 drives the first reel 531 to rotate in the direction E2. Compared with the example that the flexible screen 110 is wound on a single reel, the winding member 530 in this example has a larger volume, and the bending degree of the flexible screen 110 is smaller, so that the volume of the display device 10 (in the storage state) and the bending degree of the flexible screen 110 can be well balanced, the housing 130 can have a smaller volume, and the flexible screen 110 can be prevented from being excessively bent to greatly affect the service life of the flexible screen 110.
In the two embodiments of the storage assembly 500 and the storage driving assembly 300, when the sliding member 510 extends and retracts the flexible screen 110, the flexible screen 110 is relatively flat in the housing 130, and the bending degree of the flexible screen 110 is reduced. When the flexible panel 110 is stretched and contracted by the winding member 530, the volume of the flexible panel 110 wound around the winding member 530 is small, which is advantageous for downsizing the display device 10.
In some embodiments, with continued reference to fig. 9, the support device 20 can further include a support spool 543, and the support spool 543 can be coupled to the housing 130. The axial surface of the supporting scroll 543 is used for supporting the surface of the light emitting side of the flexible screen 110, the supporting scroll 543 can ensure that the flexible screen 110 is in a stable tensioning state, and the flexible screen 110 can be prevented from being worn by the contact between the shell 130 and the flexible screen 110.
The support spool 543 may be rotatably connected to the housing 130. During the process of extending and retracting the flexible screen 110, the supporting roller 543 can rotate to reduce the friction between the flexible screen 110 and the supporting roller 543, thereby reducing the abrasion of the supporting roller 543 to the flexible screen 110. In some examples, the supporting roller 543 may be connected to a driving member, and the driving member drives the supporting roller 543 to rotate during the process of extending and retracting the flexible screen 110. For example, referring to fig. 9, during the extending process of the flexible screen 110, the driving member drives the supporting roller 543 to rotate in the direction E2; during the process of storing the flexible screen 110, the driving member drives the supporting roller 543 to rotate in the direction E1. In other examples, when the supporting device 20 is switched between the storage state and the extending state, the flexible screen 110 can drive the supporting roller 543 to rotate, so that a driving part for the supporting roller 543 is not required, and the structure of the supporting device 20 is simplified.
Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and these modifications or substitutions do not depart from the scope of the technical solutions of the embodiments of the present application.
