Fig. 1 and fig. 2 are schematic structural diagrams of a flexible screen expansion mechanism provided in an embodiment of the present application. In the flexible screen expansion mechanism, the flexible screen expansion mechanism comprises a firstaccommodating component 2 and a flatplate supporting component 3, wherein a flat plate tooth-shapedstructure 303 is formed at one side edge of the flatplate supporting component 3 for supporting the flexible screen 1, a first accommodating tooth-shapedstructure 201 is arranged on the firstaccommodating component 2 for accommodating or releasing the flexible screen 1, the flat plate tooth-shapedstructure 303 and the first accommodating tooth-shapedstructure 201 are in staggered fit, and the firstaccommodating component 2 can slide to be close to or far away from the flatplate supporting component 3. Can drive flexible screen 1 and retrieve whenfirst storage assembly 2 is close to dull and stereotyped supportingcomponent 3, can drive flexible screen 1 extension whenfirst storage assembly 2 keeps away from dull and stereotyped supportingcomponent 3.
The flexible screen expansion mechanism in the above embodiment mainly includes a flatplate supporting component 3 and afirst receiving component 2, where the flat plate supporting component is used for supporting the flexible screen 1, and thefirst receiving component 2 is used for receiving or releasing the flexible screen 1. The small screen state of the flexible screen is shown in fig. 3, at this time, the first receivingassembly 2 abuts against thepanel supporting assembly 3, a part of the flexible screen is received in the first receivingassembly 2, and at this time, thepanel tooth structures 303 arranged in a staggered fit are completely engaged with the first receivingtooth structure 201. When the flexible screen needs to be expanded, thefirst storage assembly 2 is driven to move in the direction away from the flatplate supporting assembly 3, and the flexible screen is driven to expand, so that the flexible screen stored in thefirst storage assembly 2 is gradually released, and the large screen state as shown in fig. 4 is realized. Specifically, the flatpanel supporting assembly 3 includes a flat supportingplate 301 and a firstaccommodating assembly 2 disposed on one side of the flat supportingplate 301, wherein the flat supportingplate 301 serves as a main structure of the flatpanel supporting assembly 3, when the flat panel is in a small-screen state as shown in fig. 3, the display surface of the flexible screen 1 is attached to and supported by the flat supportingplate 301 of the flatpanel supporting assembly 3, and when the large-screen state as shown in fig. 4 is achieved, the staggered flatpanel tooth structures 303 are gradually separated from the firstaccommodating tooth structures 201 from a completely engaged state, and since gaps of the tooth structures are small, the staggered tooth structures can still provide a rigid supporting plane for the flexible screen 1 thereon, thereby ensuring normal operation of the flexible screen of a newly expanded portion. It should be understood by those skilled in the art that the upper surfaces of the first receiving component and the flat plate supporting component should be kept in the same plane in the process that the flat plate tooth-shaped structure 303 approaches or leaves the first receiving tooth-shaped structure 201 to obtain the supporting effect on the flexible screen 1, and the specific implementation process may have various specific forms, for example, the teeth of the tooth-shaped structures at both sides are set as strip-shaped teeth, and are set in a mutually attached form in a matching state, and in the process of approaching or leaving, sliding limit may be generated between the mutually attached teeth, so as to ensure the linear sliding of the first receiving component; for another example, even if the teeth of the tooth-shaped structures on the two sides are in a wedge-shaped structure or a triangular structure, or the strip-shaped teeth on the two sides of the strip are not attached to each other in a matching state, and a gap is still left, a sliding limiting component can be arranged between the flat plate supporting component 3 and the first accommodating component 2 to realize linear sliding, and the sliding limiting component includes but is not limited to the matching of a sliding block and a sleeve and the matching of a convex block and a groove; for another example, in order to prevent the first receiving assembly 2 from rotating or translating in the up-and-down direction during the sliding process when approaching or departing from the tablet supporting assembly 3, a limiting assembly in another direction may be added, for example, the back surface of the tablet supporting assembly 3 and the back surface of the first receiving assembly 2 may be connected by a sliding structure that is engaged or buckled with each other, so as to achieve the limiting of the two in the rotating direction and the vertical direction.
Specifically, theplate tooth structure 303 and the first receivingtooth structure 201 both include a plurality of teeth, and the teeth on both sides are in staggered fit. The flat plate tooth-shapedstructure 303 or the first tooth-shapedstructure 201 for accommodating is specifically selected according to the use habit of the user and the characteristics of different flexible screens, as long as the tooth-shaped structure can be realized, the flexible screen covered on the flat plate tooth-shaped structure still can obtain good support without influencing the normal work of the flexible screen.
In order to achieve a better use effect, on the basis of the above embodiment, in the sliding stroke of the first receivingassembly 2, the plate tooth-shapedstructure 303 and the first receiving tooth-shapedstructure 201 are always in a staggered fit state, that is, the tooth tips of the two tooth-shaped structures are not separated from each other to generate a gap, so that the gap generated after the two tooth-shaped structures are separated from each other is prevented from being too wide to support the flexible screen. The sliding stroke of thefirst storage assembly 2 can be specifically limited in various ways, for example, a limiting member can be arranged at an extreme position for limiting the sliding of thefirst storage assembly 2, and the stroke range of thefirst storage assembly 2 can be limited by the size of the flexible screen.
It should be noted that, in the above embodiment, only a specific technical solution with one receiving assembly is listed, but a plurality of receiving assemblies may be further provided in the embodiment of the present application, so as to realize expansion of the flexible screen in multiple directions, and a common manner in actual use is to perform bidirectional expansion of the flexible screen on two opposite sides, for example, to realize expansion of a mobile phone screen on the left and right sides. Therefore, as a preferred embodiment, the opposite side edge of theplate supporting member 3 in the embodiment of the present application is further provided with asecond receiving member 4, and the structure of the second receivingmember 4 and the connection manner of the second receivingmember 4 and theplate supporting member 3 are the same as those of the first receivingmember 2. That is, the plate tooth-shapedstructure 303 is formed on the opposite edge of theplate support member 3, the second receiving tooth-shapedstructure 401 is disposed on the second receivingmember 4, the plate tooth-shapedstructure 303 and the second receiving tooth-shapedstructure 401 are in staggered fit, and the second receivingmember 4 can slide to approach or depart from theplate support member 3. Can drive flexible screen 1 and retrieve whensecond storage assembly 4 is close to dull and stereotyped supportingcomponent 3, can drive flexible screen 1 extension whensecond storage assembly 4 keeps away from dull and stereotyped supportingcomponent 3. This design concept is applicable to the embodiments described below in this document, and the extending direction of the flexible screen is not limited to one direction.
Fig. 5 to 7 are schematic structural views of a first receiving assembly according to an embodiment of the present disclosure. As can be seen, on the basis of the above embodiment, thefirst storage assembly 2 further includes a firstrotating shaft 203 and a first windingdrum 202 rotating around the firstrotating shaft 203, and the first windingdrum 202 is used for winding the flexible screen 1. One side of the flexible screen 1 can be wound and wound on thefirst reel 202, and the flexible screen 1 can be accommodated or released on thefirst reel 202 by the rotation of thefirst reel 202 around the firstrotating shaft 203. Similarly, thesecond receiving assembly 4 for receiving or releasing the opposite flexible screen includes, in addition to the second receivingtooth structure 401 staggered with theplate tooth structure 303, a second rotating shaft connected to the second receivingtooth structure 401 and a second windingdrum 402 rotating around the second rotating shaft, where the second windingdrum 402 is used for winding the other side of the flexible screen 1. Two side edges of the flexible screen 1 can be wound on the first windingdrum 202 and the second windingdrum 402, and the flexible screen 1 can be accommodated or released on the first windingdrum 202 and the second windingdrum 402 through the rotation of the first windingdrum 202 around the firstrotating shaft 203 and the rotation of the second windingdrum 402 around the second rotating shaft.
Fig. 8 and 9 are schematic diagrams illustrating an operation process of a flexible screen expansion mechanism according to an embodiment of the present application. As shown in the figure, when the flexible screen needs to be expanded, the first receivingassembly 3 and thesecond receiving assembly 4 are pushed in the direction of the arrow shown in the figure, the first receivingassembly 2 and thesecond receiving assembly 4 move to the two sides of the whole machine, the first windingdrum 202 and the second windingdrum 402 rotate in the direction of the arrow shown in fig. 8, and the flexible screen 1 which is coiled and received at the two sides is gradually released. Meanwhile, theplate tooth structures 303 on the two sides of theplate support component 3 are gradually separated from the firstaccommodating tooth structure 201 and the secondaccommodating tooth structure 401, and the staggered tooth structures can still provide a rigid support plane for the flexible screen 1 thereon because the gaps between the tooth structures are very small.
As a further example, as shown in fig. 6 and 7, thefirst housing assembly 2 further includes afirst spring 204, thefirst spring 204 being gradually tightened as thefirst spool 202 rotates, generating a return force. Of course, thefirst spring 204 will gradually contract and generate a reset force when the first windingtube 202 rotates in one direction, and then the shape of thefirst spring 204 will gradually recover and the reset force will gradually disappear when the first windingtube 202 rotates in the opposite direction. For example, as the flexible screen 1 expands, thefirst spring 204 gradually tightens with the rotation of thefirst reel 202, generating a return force, and as the flexible screen 1 retracts, the tightenedfirst spring 204 may power the rotation of thefirst reel 202. Likewise, thesecond housing assembly 4 may further include a second spring that is gradually tightened as the second windingdrum 402 rotates to generate a restoring force when the flexible screen 1 is expanded. Upon retraction of the flexible screen 1, the second winding spring being wound may power the rotation of the second windingdrum 402.
As shown in fig. 10, aslider 304 is slidably disposed on theplate support member 3, and the first receivingmember 2 or the second receivingmember 4 is driven to approach or separate from theplate support member 3 by the reciprocal sliding of theslider 304. Preferably, the sliding direction of the sliding block along theplate supporting component 3 is the same as the direction of thefirst receiving component 2 or thesecond receiving component 4 driven by the sliding block, so that a better use experience can be obtained during control.
In a preferred embodiment, the slidingblock 304 is formed with apush button 302 protruding from the flatplate supporting component 3, and the sliding of the slidingblock 304 can be controlled by thepush button 302, so as to further achieve the recovery and expansion of the flexible screen. More preferably, as shown in fig. 10, thepush button 302 is disposed near the center line of the whole machine.
Specifically, the flexible screen expansion mechanism further comprises aseparation structure 5, and thefirst storage component 2 or thesecond storage component 4 is close to or far away from the flatplate support component 3 through theseparation structure 5.

Fig. 10 is a schematic structural view of a first separation structure in a flexible screen recovery state; fig. 11 is a schematic structural view of a first separation structure in an expanded state of the flexible screen.
As shown in the figure, the separatingstructure 5 includes a connectingrod 503, and anoutside separating rod 501 with two ends respectively rotatably connected to the connectingrod 503 and the firstaccommodating component 2, and the connectingrod 503 drives theoutside separating rod 501 to switch between a retracted state and an extended state. When theouter separating rod 501 is in the contracted state, the firstaccommodating component 2 or the secondaccommodating component 4 is in a position close to the flatplate supporting component 3, and at the moment, the flexible screen 1 is in the expanded state; when theoutside separation lever 501 is in the extended state, thefirst storage assembly 2 or thesecond storage assembly 4 is in a position away from the flatpanel support assembly 3, and the flexible screen 1 is in the retracted state.
In a further embodiment, the separatingstructure 5 may cooperate with the slidingblock 304 in other embodiments, and the connectingrod 503 is driven to move by the reciprocating sliding of the slidingblock 304. Aninclined slide groove 305 is formed in theslide block 304, and one end of thelink 503 is slidably connected to theslide groove 305.
When the flexible screen needs to be retracted, taking the separation structure on the left side in the figure as an example, thepush button 302 is pushed to move rightwards, a thrust perpendicular to the inner inclined plane of the groove is generated on the contact point of theinclined groove 305 on the slidingblock 304 driven by thepush button 302 and the bottom end of the connectingrod 503, and according to the force decomposition principle, the thrust can be decomposed into a vertically downward thrust to drive the connectingrod 503 to move vertically downward. Along with the downward movement of the connectingrod 503, theouter separating rod 501 is gradually retracted, the included angle between theouter separating rod 501 and the connectingrod 503 is gradually reduced, and the firstaccommodating component 2 and the secondaccommodating component 4 are gradually combined with the flatplate supporting component 3, so that the flexible screen is retracted, and the state shown in fig. 10 is realized.
When the flexible screen needs to be expanded, taking the left separation structure as an example, thepush button 302 is pushed to move leftward, a thrust perpendicular to the inner oblique surface of the groove is generated at a contact point of theoblique groove 305 on theslider 304 driven by thepush button 302 and the bottom end of the connectingrod 503, and according to the force decomposition principle, the thrust is decomposed into a vertically upward thrust to push the connectingrod 503 to move vertically upward. With the upward movement of thelink 503, theoutside separation lever 501 is gradually flattened and tends to be perpendicular to thelink 503, thereby pushing thefirst storage assembly 2 and thesecond storage assembly 4 to move to the left and right sides, respectively, to be separated from the flatplate support assembly 3, and thus achieving the state shown in fig. 11.

The second separation structure may further increase the deployed area of the flexible screen relative to the first separation structure.
When the flexible screen needs to be expanded, taking the left-side separation structure in fig. 14 as an example, thepush button 302 is pushed to move to the left, as can be seen from the detail enlarged view in fig. 15, an inclined plane perpendicular to the groove inner surface is generated at the contact point of theinclined groove 305 on theslider 304 driven by thepush button 302 and the bottom end of the connecting rod 503Upward and leftward thrust F1Thrust F according to the principle of force resolution1Can decompose vertical upward thrust F2The push link 503 moves vertically upward. With the upward movement of thelink 503, theoutside separation lever 501 and theinside separation lever 502 are gradually flattened, thereby pushing thefirst storage assembly 2 and thesecond storage assembly 4 to move to the left and right sides, respectively, to be separated from the flatplate support assembly 3, and achieving the state shown in fig. 14.
When the flexible screen needs to be retracted, taking the left-side separation structure of fig. 16 as an example, thepush button 302 is pushed to move to the right, and as can be seen from the detailed enlarged view of fig. 17, a pushing force F perpendicular to the inner slope of the groove and downward to the right is generated on the contact point of theinclined groove 305 on theslider 304 driven by thepush button 302 and the bottom end of the connectingrod 5031Thrust F according to the principle of force resolution1Can decompose vertical downward thrust F2Thelink 503 is driven to move vertically downward. With the downward movement of thelink 503, theoutside separation lever 501 and theinside separation lever 502 are gradually retracted. Thefirst receiving assembly 2 and thesecond receiving assembly 4 are then gradually combined with the flatplate supporting assembly 3 to complete the retraction of the flexible screen, and the state shown in fig. 16 is realized.

In addition, theouter separating rods 501 and theinner separating rods 502 in the second separating structure can be rotatably connected to the same positions of the connectingrods 503 in a one-to-one correspondence manner, so that theouter separating rods 501 and theinner separating rods 502 can gradually change from the extended state of the linear structure to the contracted state of the V-shaped structure during the flexible screen recovery process, and theouter separating rods 501 and theinner separating rods 502 can gradually change from the contracted state of the V-shaped structure to the extended state of the linear structure during the flexible screen expansion process.
