Description

Flexible screen hinge structure

This creation is about a hinge, especially a flexible screen hinge structure of a foldable electronic device.

In the existing "flexible screen folding device", according to the inward or outward folding of the flexible screen and the curvature of the curved part, different shaft structure designs are required to avoid hindering the folding action of the flexible screen and causing pulling. The folding device of the flexible screen folds inwards mainly follows the traditional folding device in the opening and closing action. After folding, the flexible screen can be protected inside, and it is relatively close to the user's habit and is easy to accept. However, in this type of product, the structural design of the hinge structure will be limited by the type of flexible screen used. It is also necessary to consider that the curved part of the flexible screen after folding inwards will be in either a drop shape or a horseshoe shape, resulting in differences. Among them, for the drop-shaped rotating shaft structure, the components that need to be considered and the connection relationship and movement between them are the key factors that affect the susceptibility to damage and the service life of the flexible screen; and because there are many components required, it is a very challenging issue in manufacturing and assembling.

For the drop-shaped shaft structure, as shown in patents CN110630625B, CN109469680B, CN109654113B, and CN209959699U, various structural designs and flexible screens are tried to achieve both thinness and overall aesthetics. However, under the consideration of the existing manufacturing process and cost, in order to achieve the effect of thinning, the effect of forming a virtual rotation center when the hinge structure is folded is better, for example: the "single virtual rotation center" disclosed in the schemas of CN110630625B and CN209959699U patents. However, in order to make the overall mechanism move closer to the water drop shape after the flexible screen is folded inwards to reduce damage, it has been successively developed into, for example: CN209514482U, CN210518418U/CN210779707U, CN112995368B and TW M633678 respectively disclosed the structure of "double virtual rotation center" and "single and double crank linkage mechanism", but its overall manufacturing and assembly It is more complex than the previous "drop-shaped hinge structure", and has higher specifications and quality requirements; and when the "hinge structure" is folded to flip at different angles, it is often impossible to make the instantaneous angle smooth to adjust the instantaneous posture of the flexible screen, thereby reducing the chance of damage when the flexible screen is folded inward.

The other end of housing link 31 has a limiter 315, limiter 315 comprises a third projection 316, a first limiter 317 and a second limiter 318, the third projection 316 is parallel to the second limiter 314, the two ends of the third projection 316 respectively extend the first limiter 317 and the second limiter 318, the first limiter 317 and the second limiter 318 are parallel to each other; 7. The third protruding block 316 and the second limiting block 318 jointly frame an accommodation space 319. There is a guide post 310 in the accommodation space 319.

The first gear 51 is pivotally connected to the first shaft 93, and the second gear 53 is pivotally connected to one of the second shaft 94 of the two shafts; One end of 4 passes through another gap of the support plate 7, and then connects and positions the shaft hole at one end of another gear connecting rod 34', so that the other gear connecting rod 34' rotates synchronously with the second shaft rod 94, and simultaneously allows the two gear connecting rods (34, 34') to rotate and open in opposite directions.

When the other end of the first shaft 93 and the other end of the second shaft 94 pass through the two fins (42, 42') of the support seat 4 respectively, and then pass through a torsion positioning assembly 6, and respectively use a first end seal 61 and a second end seal 62 to lock the first shaft 93 and the second shaft 94, the compression torsion positioning assembly 6 can be fixed, and then the two halves of the flexible screen 9 that are relatively bent can rotate stably during the process of turning over to close or fully unfolding, and freely stop when rotating stay at a certain angle.

Thereby, as shown in Fig. 3, Fig. 5 ~ Fig. 10, when the casing 91 is fully unfolded or folded and closed relative to the casing 91', for example: during the transition from folded and unfolded to a closed state, when one shaft module 3 rotates relative to the other shaft module 3', taking one side as an example, the gear connecting rod 34 and the casing connecting rod 31 produce a relative displacement, that is, the sliding part 341 passes through the perforations on the first convex part 342 and the second convex part 343 to move away from the first stopper 317 along the direction The guide post 310 slides axially; at the same time, the connecting plate 32 is subjected to the pulling force of the tension spring 35, so that the guide rod 322 always slides on the curved track 345, thereby driving the door panel 92 and another door panel 92' to form a water drop space for accommodating the redundant part of the flexible screen 9 when it is folded into a closed state.

As shown in Fig. 12, Fig. 13 and Fig. 14, it is the second embodiment of the flexible screen rotating shaft structure 1 of the present invention. It is different from the first embodiment in that: taking one of the rotating shaft modules (3, 3') as an example, the other end of the connecting plate 32 is extended with two bending pieces (323, 323') arranged side by side at intervals, and a limiting plate (334, 334') is extended outwards on both sides of the arc swing arm 33 respectively. When the two rotating shaft modules (3, 3') are relatively rotated and closed, the two bending pieces (323, 323') can be used to abut against the two limiting plates (334, 334') in the form of rails to provide a limit guiding effect, and then when the action of the tension spring 35 is not needed, only the two bending pieces (323, 323') abut against the two limiting plates (334, 334') to generate relative displacement, so that the guide rod 322 is always in position. Slip on the curved track 345, so that the two door panels (92, 92') form a water drop space for accommodating the redundant part in the middle of the flexible screen 9. And when the tension spring 35 is provided, taking one side as an example, it can further provide the tension that the connecting plate 32 continuously fits the gear connecting rod 34 and the arc swing arm 33, so that the guide rod 322 can always slide on the curved track 345, and let the bending piece 323 continue to contact the limit plate 334, thereby making the turning more smooth and the structure more stable.

To sum up, this creation can not only simplify the components and improve the convenience of assembly through the improvement of the overall shape and the dispersion of the structure, but also reduce the manufacturing and assembly costs; and because this creation uses a tension spring to connect the connecting plate and the housing connecting rod respectively, the shaft on one side of the connecting plate can be pressed against the curved track of the gear connecting rod. In addition, through the connection of the guide post, the gear connecting rod and the housing connecting rod can slide back and forth stably relative to each other, so as to increase the smoothness of use, reduce the impact of abnormal noise, and prolong the service life of the components; moreover, through the two sides of the arc-shaped swing arm of the second embodiment, a limiting plate is respectively extended outward, for the two bending pieces extended by the connecting plate to abut against each other. Smoother and more stable in structure.

Although this creation discloses preferred specific embodiments to achieve the above purpose, it is not intended to limit the structural features of this creation. Anyone with ordinary knowledge in this technical field should know that under the technical spirit of this creation, any easily conceivable changes or modifications are possible, and all of them are covered by the patent application scope of this creation.
