Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically to a hinge mechanism for flexible screens. Background Technology

[0002] As one of the more important components in foldable phones, flexible screens require hinge mechanisms to ensure that they deform smoothly when folded or unfolded. These hinge mechanisms prevent the flexible screen from being affected by the hinge components during folding and unfolding.

[0003] In some existing hinge mechanisms, when used to adjust the angle of a flexible screen, there is a gap between the central part of the hinge mechanism and the middle section of the flexible screen after bending. Because the flexible screen itself is flexible, the middle section of the flexible screen is prone to concave under external force (such as manual pressing), which increases the extension of the flexible screen. When the flexible screen is unfolded later, the middle section of the flexible screen will bulge out, which needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a hinge mechanism for flexible screens to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hinge mechanism for a flexible screen, comprising a mounting plate, wherein the mounting plate is provided with two through holes, and a first gear is provided in each of the two through holes. A mounting plate is fixedly fitted on each of the first gears. A support component is provided on the side wall of the two mounting plates that are close to each other to provide support for the middle section of the flexible screen. A rotating plate is movably attached to the side of the two mounting plates that are far from each other, and the rotating plate is movably fitted on the outer wall of a first gear. A second gear is rotatably mounted on each rotating plate, and a connecting platform is fixedly installed on the shaft of the second gear.

[0006] Preferably, the support component includes a lifting slide groove located on the mounting plate, and a lifting plate is slidably installed in the lifting slide groove. By having the top of the lifting plate fit against the middle section of the flexible screen, the flexible screen can be provided with a support effect.

[0007] Preferably, each of the lifting plates is fixedly installed with a linkage block, and two L-shaped limiting blocks are movably attached to the linkage block, and the L-shaped limiting blocks are fixedly installed on the side wall of the set plate.

[0008] Preferably, a support spring is provided inside the lifting slide, and the two ends of the support spring are respectively fixedly connected to the inner wall of the lifting slide and the bottom side wall of the lifting plate.

[0009] Preferably, a connecting plate is provided between the two sets of plates to provide support for the middle section of the flexible screen, and both ends of the connecting plate are fixedly connected to the lifting plate.

[0010] Preferably, anti-detachment grooves are provided on the inner walls of both sides of the lifting slide, and a sliding plate is slidably installed in each anti-detachment groove, and the sliding plate is fixedly connected to the lifting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] After the flexible screen is folded, the lifting plate is pushed upward by the support spring and fits into the middle section of the folded flexible screen to provide support. The lifting plate's movement space is restricted by the linkage block on the lifting plate and the L-shaped limit block, which prevents the middle section of the flexible screen from easily concave under external force (such as manual pressing), thus increasing the flexibility of the screen.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4This utility model provides a technical solution: a hinge mechanism for a flexible screen, including a mounting plate 1, which has two through holes. A first gear 2 is installed in each of the through holes, and a mounting plate 3 is fixedly fitted onto each of the first gear 2. Support components 7 that provide support for the middle section of the flexible screen are installed on the sidewalls of the two mounting plates 3 that are close to each other. Rotating plates 4 are movably fitted onto the sidewalls of the two mounting plates 3 that are far apart from each other, and each rotating plate 4 is movably fitted onto the outer wall of a first gear 2. A second gear 5 is rotatably mounted on each rotating plate 4. A connecting platform 6 is fixedly installed on the shaft of the second gear 5. The connecting platform 6 can be connected to the flexible screen. The first gear 2 and the adjacent second gear 5 are in a meshing state. Rotation of the first gear 2 and the second gear 5 causes the connecting platform 6 connected to the flexible screen to rotate, thus unfolding or folding the flexible screen.

[0020] The support component 7 includes a lifting slide 8 located on the mounting plate 3. A lifting plate 9 is slidably installed in the lifting slide 8. The top of the lifting plate 9 is attached to the middle section of the flexible screen to provide support for the flexible screen. Each lifting plate 9 is fixedly installed with a linkage block 10. Two L-shaped limiting blocks 11 are movably attached to the linkage block 10. The L-shaped limiting blocks 11 are fixedly installed on the side wall of the mounting plate 3. After the flexible screen is folded, the lifting plate 9 is pushed upward by the support spring 12 and attaches to the middle section of the folded flexible screen to provide support. The linkage block 10 on the lifting plate 9 is attached to the L-shaped limiting blocks 11 to limit the movement space of the lifting plate 9. When the flexible screen is unfolded, the flexible screen will push the lifting plate 9 back to the lifting slide 8.

[0021] A support spring 12 is provided inside the lifting slide 8. The two ends of the support spring 12 are fixedly connected to the inner wall of the lifting slide 8 and the bottom side wall of the lifting plate 9, respectively, so as to facilitate the lifting plate 9 to move upward and fit the flexible screen.

[0022] A connecting plate 13 is provided between the two sets of plates 3 to provide support for the middle section of the flexible screen. Both ends of the connecting plate 13 are fixedly connected to the lifting plate 9, so that the connecting plate 13 can move upward with the lifting plate 9 and fit into the flexible screen during use, providing support for the middle section of the flexible screen. Rubber sheets are provided at the top of the connecting plate 13 and the lifting plate 9 to protect the flexible screen.

[0023] Anti-detachment grooves are provided on the inner walls of both sides of the lifting slide 8, and slide plates are slidably installed in the anti-detachment grooves. The slide plates are fixedly connected to the lifting plate 9 to ensure that the lifting plate 9 can move vertically up and down.

[0024] Working principle: After the flexible screen is bent and folded by the first gear 2 and the second gear 5, there is a gap between the middle section of the flexible screen and the mounting plate 3. At this time, the lifting plate 9 and the connecting plate 13 are pushed upward by the support spring 12 and fit into the flexible screen to provide support for the flexible screen. The lifting space of the linkage block 10 and the lifting plate 9 is restricted by the L-shaped limit block 11.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
