Background

The folding flexible screen and the electronic equipment are convenient to carry. And double display effect is obtained when the display device is used and flattened, so that the requirement of a user on a large screen is met. For electronic equipment with an inward-folding flexible screen, when the flexible screen is folded, part of the bending area of the flexible screen can enter the shell in the middle of the electronic equipment with the inward-folding flexible screen, and part of the upper rotating plate and the lower rotating plate (or left and right rotating plates) are attached to the screen. The movement structure and the support of the whole hinge structure are very important for the folding-in flexible screen.

The biggest problem with the in-turned folding mechanism is also length compensation. In particular to a mainstream-invaginated water drop type flexible screen of the current invaginated flexible screen. When the folding area meets the length compensation, the flexible screen is folded into a predetermined water drop shape by the folding area setting mechanism so as to be convenient for more space for accommodating the folding area, thereby supporting the shape of the flexible screen when being folded, and prolonging the service life of the screen. In the related art, the folding mechanism has more parts, more complex design, high production cost and high installation difficulty.

The damping ring 63 is provided with a plurality of first protrusions 64 circumferentially arranged on a side facing the first rotating portion 51, two adjacent first protrusions 64 define a first groove 65, the first rotating portion 51 is provided with a plurality of second protrusions 512 circumferentially arranged on a side facing the damping ring 63, two adjacent second protrusions 512 define a second groove 513, the first protrusions 64 are fitted in the second grooves 513, and the second protrusions 512 are fitted in the first grooves 65. Specifically, under the action of the elastic member 62, the damping ring 63 cooperates with the respective first rotating portion 61 such that the first projection 64 abuts in the respective second recess 513, and the second projection 512 abuts in the respective first recess 65. So that the damping ring 63 can provide a rotation resistance for the corresponding first rotation part 51 through the first protrusion 64 and the second groove 513, the second protrusion 512 and the first groove 65 which are matched with each other without being stirred by the outside, so that the first rotation part 51 cannot rotate under the action of gravity. When the first rotating portion 51 is required to rotate, the connecting piece 3 can be manually shifted to rotate so as to drive the limiting piece 5 to rotate, so that the second protrusion 512 rotates relative to the damping ring 63, and the second protrusion 512 enters the adjacent first groove 65, and the second groove 513 is matched with the adjacent first protrusion 64. So that the limiter 5 as well as the connector 3 and the support 4 can hover.

In some embodiments, the first groove 65 has a first slope that mates with the second protrusion 512 and/or the second groove 513 has a second slope that mates with the first protrusion 64. The first groove 65 has a first slope that mates with the second protrusion 512 and/or the second groove 513 has a second slope that mates with the first protrusion 64 includes a. The first groove 65 has a first slope that mates with the second protrusion 512; b. the second groove 513 has a second slope that mates with the first protrusion 64; c. the first groove 65 has a first slope that mates with the second protrusion 512, and the second groove 513 has a second slope that mates with the first protrusion 64. Specifically, the first projection 64 has a first inclined surface on the side in the circumferential direction of the gear shaft 6, the first inclined surface facing the second projection 512 and increasing in distance from the first rotating portion 51 in a direction away from the center of the first projection 64, and the second projection 512 has a second inclined surface facing the first projection 64 and increasing in distance from the damper ring 63 in a direction away from the center of the second projection 512. Thereby, the damping ring 63 can be made to increase a certain resistance for the corresponding first rotating portion 51.

In some embodiments, the first rotating portion 51 of each stopper 5 is provided with a damper ring 63 on both sides in the length direction of the mount 1. Thereby, the hovering of the limiter 5 can be further facilitated. For example, the damper ring 63 is provided on both sides in the front-rear direction of each first rotating portion 51 with the teeth 511, the first rotating portion 51 without the teeth 511 does not cooperate with the damper ring 63, and the first rotating portion 51 without the teeth 511 is fixed to the mount 1 by a rotation shaft.

The two damper rings 63 located on the same side of the first rotating portion 51 in the length direction of the mounting member 1 are connected by the connecting rod 631, that is, the two damper rings 63 located on the same side of the first rotating portion 51 in the length direction of the mounting member 1 are fixedly connected, so that the damper rings 63 can be prevented from rotating to provide rotational resistance to the corresponding first rotating portion 51.

In some embodiments, the elastic member 62 is a spring, and the spring is sleeved on the gear shaft 6, and two ends of the spring are respectively connected with the mounting member 1 and the damping ring 63, so that the damping ring 63 can be conveniently matched with the first rotating part 51.
