Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the utility model and implement it, but the examples given are not intended to limit the utility model.

The utility model provides a roll-up flexible display device, as shown in Figure 1 and Figure 2, comprising a flexible display 4, two opposite sides of the back of the flexible display 4, that is, non-display areas 401, are respectively pasted with card slots Column 6, the display area 402 of the flexible display screen 4 is in the middle of the two columns of non-display areas 401 . The slot row 6 is a strip structure, which can be glued to the non-display area 401 of the flexible display 4, and the slot row 6 can be rolled and unfolded together with the flexible display 4, thus not affecting The storage of the flexible display 4 and the double-sided display function of the flexible display 4 itself. Moreover, since the card slot row 6 can be curled and bent, the flexible display screen 4 can perform a curved display in a certain arc, which can meet the display requirements of some special display areas. The other two opposite sides of the flexible display screen 4 are respectively connected to the rotating shaft 1 and the card strip 3, the rotating shaft 1 is arranged inside the shell 2 with an opening on the side, when the flexible display screen 4 is curled and stored, the card The bar 3 is correspondingly stopped at the opening position. The flexible display screen 4 can be unfolded by pulling the clip bar 3 , and at the same time, the flexible display screen 4 can be effectively stored and pulled by the stopper of the clip bar 3 .

The roll-up flexible display device realizes the function of automatic retraction after the flexible display screen 4 is pulled and unfolded by means of a clockwork. Spring is an existing mature mechanical device, which is briefly introduced in the utility model. Both ends of the rotating shaft 1 are respectively wound with two mainsprings, one end of the mainspring is fixed to the rotating shaft 1 , and the other end is fixed to the inner wall of the casing 2 . When the flexible display screen 4 is pulled out, the spring is wound and tightened to store elastic deformation energy. When the flexible display screen 4 is released, the elastic deformation energy is released, and the spring is driven by the elastic force. The bar recovers its deformation, and then drives the rotating shaft 1 to rotate, and drives the flexible display screen 4 to be wound up.

The inside of the housing 2 has a clip 5 at a position corresponding to the slot row 6 , and the clip 5 is correspondingly snapped into the slot 602 of the slot row 6 . As shown in Figure 3, the clip 5 includes a connecting shaft 502, and also includes two clips 501 that are rotatably connected by the connecting shaft 502 and corresponding to the two rows of slot columns 6, and the two clips 501 are located on both sides correspondingly. The draw-in slot 602 position of the draw-in slot row 6, and one end of the connecting shaft 502 has a button 503, the button 503 can control the turning of the connecting shaft 502, pressing the button 503 can make the connecting shaft 502 rotate a certain angle, and then make the clip 501 The end leg of the clip 501 is lifted, and the end leg of the clip 501 can be engaged in the slot 602 by releasing the button 503 . The side of the housing 2 may have a through hole through which the button 503 is exposed to the outside of the housing 2 .

The slot row 6 is composed of a plurality of continuous zigzag protrusion structures 601, two adjacent protrusion structures 601 form a slot 602, as shown in Figure 4, the end pins of the clip 501 of the clip 5 can be engaged fit in the card slot 602 , and then when the flexible display screen 4 is drawn to the size required to be displayed, the clip 501 of the clip 5 can be used to realize stability and fixation. The material of the slot row 6 is plastic, which does not affect the retraction of the flexible display screen 4, and when the flexible display screen 4 is housed in the housing 2, as shown in FIG. The flexible display screens 4 are separated from each other to avoid friction and damage to the flexible display screens 4 .

The working principle of the roll-up flexible display device provided by the utility model is obtained according to the principle of a tape measure. After being stretched, the flexible display screen 4 can automatically shrink back and wind up on the rotating shaft 1 . As shown in Figure 4, the clip 5 is located inside the casing 2, and the two clips 501 and the button 503 are connected through the connecting shaft 502. When the button 503 is pressed, the ends of the two clips 501 are lifted, and the stretched flexible display 4 is pulled out. Pull to the required display size, when the button 503 is put down, the end legs of the two clips 501 are stuck in the slot 602 of the slot column 6, and the flexible display screen 4 is fixed and cannot be stretched automatically. When the flexible display screen 4 needs to be put away, the button 503 is pressed, and the end legs of the two clips 501 are lifted, and the flexible display screen 4 is automatically retracted and wound on the rotating shaft 1 .
