1 and 2 are schematic structural diagrams of a flexible screen expansion mechanism provided by an embodiment of the present disclosure. The flexible screen expansion mechanism includes a first storage assembly 2 and a flat support assembly 3, wherein a flat tooth structure 303 is formed on one side edge of the flat support assembly 3 for supporting the flexible screen 1 for storing or releasing flexibility The first storage component 2 of the screen 1 is provided with a first storage tooth structure 201, and the flat plate tooth structure 303 interlaces with the first storage tooth structure 201, and the first storage component 2 is slidably close to or away from the flat support Component 3. When the first storage component 2 approaches the tablet support assembly 3, it will drive the flexible screen 1 to recover, and when the first storage component 2 moves away from the tablet support assembly 3, it will drive the flexible screen 1 to expand.

The flexible screen expansion mechanism in the above embodiment mainly includes a tablet support assembly 3 and a first storage assembly 2, wherein the tablet support assembly is used to support the flexible screen 1, and the first storage assembly 2 is used to store or release the flexible screen 1. The small screen state of the flexible screen is shown in FIG. 3, at this time, the first storage component 2 is close to the flat support component 3, and a part of the flexible screen is stored in the first storage component 2. 303 is completely engaged with the first storage tooth structure 201. When it is necessary to expand the flexible screen, the first storage assembly 2 is driven to move away from the tablet support assembly 3, and at the same time, the flexible screen is expanded, so that the flexible screen stored in the first storage assembly 2 is gradually released, as shown in FIG. 4 The large screen status shown. In one embodiment, the flat support assembly 3 includes a flat support plate 301 and a first storage assembly 2 disposed on the side of the flat support plate 301, wherein the flat support plate 301 serves as the main structure of the flat support assembly 3, as shown in FIG. 3 In the small screen state shown, the display surface of the flexible screen 1 is in close contact with and supported by the flat support plate 301 of the tablet support assembly 3, and in the process of realizing the large screen state shown in FIG. The first storage tooth structure 201 is gradually separated from the fully occluded state. Because the gap of the tooth structure is small, the staggered tooth structure can still provide a rigid support plane for the flexible screen 1 thereon, ensuring new The flexible screen of the extension part works normally. Those of ordinary skill in the art should understand that when the flat tooth structure 303 approaches or is away from the first storage tooth structure 201, the upper surface of the first storage component and the flat support component should be kept in the same plane to obtain the flexible screen 1 The specific supporting process of the supporting effect can have many specific forms. For example, the teeth of the tooth structure on both sides can be set as strip teeth, and they can be set to fit each other in the fitted state. In the process of being away from each other, there will be a sliding limit between the teeth that fit each other, so as to ensure the linear sliding of the first storage assembly; The strip teeth on both sides do not fit each other in the mated state, and there is still a gap, you can also set a sliding limit component between the flat support component 3 and the first storage component 2 to achieve linear sliding, sliding limit Components include but are not limited to the cooperation of the slider and the sleeve and the projection and the groove; in another example, in order to prevent the first storage component 2 from approaching or away from the flat plate Rotation or translation in the up-down direction occurs during the sliding of the support assembly 3, and a limit assembly in another direction can be added, for example, the back of the flat support assembly 3 and the back of the first storage assembly 2 can be fitted or snapped with each other The sliding structure is connected to achieve the limit of the two in the rotation direction and the vertical direction.

In one embodiment, both the flat tooth structure 303 and the first storage tooth structure 201 include a plurality of teeth, and the teeth on both sides are interleaved. The width of the tooth gap of the flat tooth structure 303 or the first storage tooth structure 201 can be selected according to the user's usage habits and the characteristics of different flexible screens, as long as the width of the tooth gap can be achieved, the flexible screen covering it remains Good support can be obtained without affecting its normal work.

In order to achieve a better use effect, on the basis of the above embodiment, the flat tooth structure 303 and the first storage tooth structure 201 are always in a staggered fit state within the sliding stroke of the first storage assembly 2, that is, The gap between the tooth tips of the two tooth-shaped structures will not cause separation, so as to prevent the gap generated after separation of the two from being too wide to support the flexible screen. The sliding stroke of the first storage component 2 can be specifically defined in various ways, for example, by setting a stopper at the limit position that limits the sliding of the first storage component 2, or by the size of the flexible screen to define the first storage component 2 Stroke range etc.

It should be noted that the above embodiment only lists a specific technical solution with one storage component, but the storage component in the embodiment of the present disclosure may also be provided with multiple, to achieve the expansion of the flexible screen in multiple directions, in A more common method in actual use is to expand the flexible screen bidirectionally on opposite sides, for example, to expand the mobile phone screen on the left and right sides. Therefore, as a preferred embodiment, the opposite side edge of the tablet support assembly 3 in the embodiment of the present disclosure is further provided with a second storage assembly 4, the structure of the second storage assembly 4 and its relationship with the flat support assembly 3 The connection methods are the same as the first storage assembly 2. In other words, a flat tooth structure 303 is formed on the opposite side edge of the flat support assembly 3, a second storage tooth structure 401 is provided on the second storage assembly 4, the flat tooth structure 303 and the second storage tooth structure In 401, the second accommodating component 4 can slide close to or away from the flat supporting component 3 in a staggered fit. When the second storage component 4 is close to the tablet support component 3, the flexible screen 1 is driven to be recovered, and when the second storage component 4 is far from the tablet support component 3, the flexible screen 1 is driven to expand. This design idea is applicable to the specific embodiments below in this disclosure, and the expansion direction of the flexible screen is not limited to one direction.

5-7 are schematic structural diagrams of a first storage assembly provided by an embodiment of the present disclosure. It can be seen from the figure that, on the basis of the foregoing embodiment, the first storage assembly 2 further includes a first rotating shaft 203 and a first reel 202 that rotates around the first rotating shaft 203. The first reel 202 is used for winding the flexible screen 1. One side of the flexible screen 1 can be wound and wound around the first reel 202. The rotation or rotation of the first reel 202 around the first rotation axis 203 realizes the storage or release of the flexible screen 1 in the first reel 202. Similarly, the second storage assembly 4 for storing or releasing the opposite flexible screen includes not only the second storage tooth structure 401 interleaved with the flat tooth structure 303, but also a connection with the second storage tooth structure 401 And a second reel 402 that rotates around the second rotation axis. The second reel 402 is used to wind the other side of the flexible screen 1. The two sides of the flexible screen 1 can be wound around the first reel 202 and the second reel 402, through the rotation of the first reel 202 around the first rotation axis 203 and the rotation of the second reel 402 around the second rotation axis The flexible screen 1 is stored or released in the first roll 202 and the second roll 402.

8 and 9 are schematic diagrams of an operation process of a flexible screen expansion mechanism provided by an embodiment of the present disclosure. As shown in the figure, when the flexible screen needs to be expanded, the first storage assembly 3 and the second storage assembly 4 are pushed in the direction of the arrow shown in the figure, and the first storage assembly 2 and the second storage assembly 4 move toward both sides of the machine, The first reel 202 and the second reel 402 rotate in the direction of the arrow shown in FIG. 8 to gradually release the flexible screen 1 curled and stored on both sides. At the same time, the flat tooth structures 303 on both sides of the flat support assembly 3 are gradually separated from the first storage tooth structure 201 and the second storage tooth structure 401. Since the gap between the tooth structures is small, the staggered tooth structures It is still possible to provide a rigid support plane for the flexible screen 1 thereon.

As a further embodiment, as shown in FIGS. 6 and 7, the first storage assembly 2 further includes a first mainspring 204 that gradually tightens as the first reel 202 rotates, generating a restoring force. Of course, the first mainspring 204 gradually tightens and generates a reset force when the first reel 202 rotates in one direction, and then when rotated in the opposite direction, the shape of the first mainspring 204 gradually recovers, and the reset force is Will gradually disappear. For example, when the flexible screen 1 expands, the first spring 204 gradually tightens with the rotation of the first reel 202, generating a reset force, and when the flexible screen 1 is recovered, the tightened first spring 204 may be the first The rotation of the reel 202 provides power. Similarly, the second storage assembly 4 may further include a second mainspring. When the flexible screen 1 is expanded, the second mainspring gradually tightens with the rotation of the second reel 402 to generate a reset force. When the flexible screen 1 is recovered, the tightened second spring can provide power for the rotation of the second reel 402.

As shown in FIG. 10, a slider 304 is slidably disposed on the tablet support assembly 3, and the first storage assembly 2 or the second storage assembly 4 is driven close to or away from the tablet support assembly 3 by the reciprocating sliding of the slider 304. In one embodiment, the sliding direction of the slider along the plate support assembly 3 is the same as the direction of the first storage assembly 2 or the second storage assembly 4 driven by it, and a better user experience can be obtained during control.

As an embodiment, the slider 304 is formed with a push button 302 protruding out of the tablet support assembly 3, and the slider 304 can be used to control the sliding of the slider 304 to further realize the recovery and expansion of the flexible screen. In one embodiment, as shown in FIG. 10, the push button 302 is disposed near the centerline of the whole machine.

In one embodiment, the flexible screen expansion mechanism further includes a separation structure 5. The separation structure 5 enables the first storage assembly 2 or the second storage assembly 4 to approach or move away from the tablet support assembly 3.

10 and 11 are schematic structural diagrams of a first separation structure provided by an embodiment of the present disclosure. FIG. 10 is a schematic diagram of the structure of the first separation structure in the state of recycling the flexible screen; FIG. 11 is a schematic diagram of the structure of the first separation structure in the state of expansion of the flexible screen.

When the outer separating rod 501 is in the retracted state, the first storage assembly 2 or the second storage assembly 4 is in a position close to the tablet support assembly 3, and the flexible screen 1 is in the expanded state at this time; when the outer separating rod 501 is in the extended state, the first One storage component 2 or the second storage component 4 is in a position away from the tablet support component 3, and the flexible screen 1 is in the recovery state at this time.

In a further embodiment, the above separation structure 5 may cooperate with the slider 304 in other embodiments, and drive the connecting rod 503 to move by the reciprocating sliding of the slider 304. The slider 304 is provided with an oblique sliding groove 305, and one end of the connecting rod 503 is slidingly connected to the sliding groove 305.

When the flexible screen needs to be retracted, taking the separation structure on the left side of the figure as an example, the push button 302 is moved to the right, and the oblique groove 305 on the slider 304 driven by the push button 302 contacts the bottom end of the connecting rod 503 At the point, a thrust force perpendicular to the lower right side of the oblique surface of the groove will be generated. According to the force decomposition principle, the thrust force will decompose the vertically downward thrust force, driving the connecting rod 503 to move vertically downward. With the downward movement of the connecting rod 503, the outer separating rod 501 is gradually recovered, and the angle between the outer separating rod 501 and the connecting rod 503 gradually becomes smaller, and the first storage assembly 2 and the second storage assembly 4 are then in contact with the plate support assembly 3 Gradually merge, complete the recovery of the flexible screen, to achieve the state shown in Figure 10.

When expansion of the flexible screen is required, taking the left-side separation structure as an example, pushing the push button 302 to move to the left, the inclined groove 305 on the slider 304 driven by the push button 302 and the bottom end of the connecting rod 503 will contact The thrust is generated perpendicular to the upper left side of the oblique surface of the groove.

Compared with the first separation structure, the second separation structure can further increase the expansion area of the flexible screen.

When the expansion of the flexible screen is required, take the left-side separation structure in FIG. 14 as an example, and push the push button 302 to move to the left. As can be seen from the detailed enlarged view of FIG. 15, the diagonal direction on the slider 304 driven by the push button 302 At the contact point between the groove 305 and the bottom end of the connecting rod 503, a thrust F ₁ perpendicular to the left of the groove and inclined upward will be generated. According to the principle of force decomposition, the thrust F ₁ will decompose the upward thrust F ₂ , pushing The connecting rod 503 moves vertically upward. With the upward movement of the connecting rod 503, the outer separating rod 501 and the inner separating rod 502 will gradually flatten out, thereby pushing the first storage assembly 2 and the second storage assembly 4 to move to the left and right sides, respectively, to separate from the plate support assembly 3, The state shown in FIG. 14 is realized.

When the flexible screen needs to be retracted, taking the separation structure on the left side of FIG. 16 as an example, the push button 302 is moved to the right. As can be seen from the detailed enlarged view of FIG. 17, the diagonal recess on the slider 304 driven by the push button 302 At the point of contact between the bottom end of the groove 305 and the connecting rod 503, a thrust F ₁ perpendicular to the inner oblique surface of the groove will be generated. According to the principle of force decomposition, the thrust F ₁ will decompose the thrust F ₂ that is vertically downward. The connecting rod 503 moves vertically downward. As the connecting rod 503 moves downward, the outer separating rod 501 and the inner separating rod 502 are gradually recovered. The first storage assembly 2 and the second storage assembly 4 are gradually merged with the tablet support assembly 3 to complete the retracting of the flexible screen, and the state shown in FIG. 16 is achieved.
