Specifically, each connecting hinge 251 is hinged with the corresponding The rotating hinges 253 rotate through a first virtual axis A1, and the two rotating hinges 253 rotate through a second virtual axis A2. The second virtual axis A2 is located between the two first virtual axes A1. The distances between the two first virtual axes A1 and the second virtual axis A2 are the same. The two connecting hinges 251 respectively rotate about the corresponding first virtual axis A1, the first positioning component 28a and the second positioning component 28b also rotate with the corresponding connecting hinge 251 about the first virtual axis A1; two rotating hinges 253 Respectively rotate around the second virtual axis A2, the first transmission assembly 271 and the corresponding connecting cover 270 and the third transmission assembly 277 rotate with the corresponding rotating hinge 253 around the second virtual axis A2, and the second transmission assembly 274 is connected to the corresponding The cover 270 and the third transmission assembly 277 rotate with the corresponding rotating hinge 253 around the second virtual axis A2. Specifically, since the first transmission component 271, the corresponding connecting cover 270, the third transmission component 277 connected to the connecting cover 270, and the corresponding rotating hinge 253 are connected in an integrated structure, the integrated structure is wound around the first The second virtual axis A2 rotates; since the second transmission component 274, the corresponding connecting cover 270, the third transmission component 277 connected to the connecting cover 270, and the corresponding rotating hinge 253 are connected to an integrated structure, the integrated structure The structure also rotates about the second virtual axis A2. Each first virtual axis A1 is spaced parallel to the second virtual axis A2, and the axis radius of the first virtual axis A1 is the same as the axis radius of the second virtual axis A2. In the flat state, the distance between the two opposite side surfaces of the two connecting hinges 251 is L, that is, the linear distance between the two connecting hinges 251 on the bent outer sides of the two connecting hinges 251 when they are flattened is L. In this embodiment, the distance between the two opposite sides of the two connecting hinges 251 is equal to the width of the bendable area 31, that is, the length of the bendable area 31 extending in the direction perpendicular to the first virtual axis A1 is equal to L . The first virtual axis A1 and the second virtual axis A2 are both located outside the hinge body 25. Preferably, the first virtual axis A1 and the second virtual axis A2 are both located on the flexible screen 30 covering the hinge body 25, thereby improving The bending resistance of the flexible screen 30 can ensure that the flexible screen 30 is not damaged to the greatest extent. Further, A1 and A2 can also be located on the neutral layer of the flexible screen.

The neutral layer means that during the bending process of the flexible screen 30, the outer layer of the flexible screen 30 is stretched, and the inner layer of the flexible screen 30 is squeezed. , The transition layer that is not squeezed or subjected to a relatively small force of stretching or squeezing, the transition layer has very little stress, and the transition layer is a neutral layer.

Each virtual axis is defined by the corresponding structure. Specifically, the virtual axis A1 can be defined by the axis of the arc at the bottom of the receiving slot 2737 or by the axis of the arc at the bottom of the connecting block 2836; the virtual axis A2 can be defined by the arc of the bottom of the connecting block 2738 The axis of the guide surface is defined by or is defined by the axis of the arc-shaped guide surface of the inner wall of the receiving groove 2767.

The flexible screen 30 is attached to the top of the arc surface of each connecting hinge/rotating hinge/positioning assembly/connection mechanism in the unfolded state, and is separated from other areas except the top of each arc surface. Through the above-mentioned virtual axis solution, the flexible screen 30 can maintain its length substantially unchanged when it is bent.

Since the inner surface of the sliding groove 2816 of the first mounting member 281 is provided with an arc-shaped receiving groove 2817 and the inner surface of the sliding groove 2856 of the second mounting member 285 is provided with an arc-shaped receiving groove 2857, the hinge device 24 is bent During the folding or flattening process, the guide posts 2616 of the two connecting rods 2611 can slide in the receiving

grooves

2817 and 2857 respectively, thereby reducing the thickness of the opening of the sliding

grooves

2816 and 2856, thereby reducing the first mounting member 281 and the second The thickness of the second mounting member 285 is so as to reduce the thickness of the entire electronic device 100.

Due to the use of a straight rack and a spur gear meshing method, compared with a helical gear meshing method, high manufacturing accuracy is not required, which can effectively reduce production costs and improve production efficiency.

It is understandable that the straight racks in each of the first gear assembly 266 and the second gear assembly 267 can also be replaced by helical gears or spur gears, spur gears can also be replaced by helical gears, or the straight racks in each gear set can be omitted. The rack, directly meshed with two spur gears, can also serve the purpose of linkage.

Place the installed hinge device 24 between the first frame 21 and the second frame 23, that is, connect the slide rail 2813 of the first positioning assembly 28a and the second positioning assembly 28b of the two connecting links 251 The sheet 2853 is connected to the first frame 21 and the second frame 23 respectively. The backs of the two non-bending areas 33 of the flexible screen 30 are attached to the first frame 21 and the second frame 23, respectively, and the back of the bendable area 31 of the flexible screen 30 is installed on the hinge device 24 positive.

Specifically, if a bending force is applied to the first frame 21, the first frame 21 drives the corresponding connecting hinge 251 and the first positioning assembly 28a at both ends of the connecting hinge 251 relative to the rotating hinge 253. The first virtual axis A1 rotates toward the side away from the flexible screen 30; the two first positioning components 28a drive the first gears 2661 of the two connecting rod members 261 to rotate along the corresponding second gears 2663 respectively. The fixing block 2621 and the second connecting shaft 2620 are relatively fixed, and the second gear 2663 is fixed on the fixing block 2621. Therefore, the second gear 2663 and the second connecting shaft 2620 are both fixed and will not rotate. The first gear 2661 can only Rotate the corresponding second gear 2663 toward the side away from the flexible screen 30, so that the connecting rod 261 rotates along the second gear 2663 toward the side away from the flexible screen 30. The connecting rod 2611 and the guide post 2616 of the connecting rod 261 are in the corresponding position. The first mounting member 281 slides in the sliding groove 2816 and the receiving groove 2817; at the same time, the connecting rod member 261 also drives the corresponding two transmission members 264 and the corresponding damping member 268 along the corresponding second connecting shaft 2620 toward and away from the flexible screen Turning on one side of 30, the transmission posts 2644 of the two transmission members 264 slide in the

corresponding toggle grooves

Since the fixing block 2621 of the fixing member 262 is relatively fixed with the second connecting shaft 2620, and the second gear 2663 is fixed on the fixing block 2621, the second gear 2663 is fixed and does not rotate. The first gear 2661 of the other connecting rod 261 can only rotate around the corresponding second gear 2663 to the side away from the flexible screen 30, so that the connecting rod of the other connecting rod 261 2611 rotates along the second gear 2663 toward the side away from the flexible screen 30; the connecting rod 2611 and the guide post 2616 of the other connecting rod 261 slidably push against the sliding groove 2856 and the receiving groove 2857 of the corresponding second mounting part 285 The second positioning component 28b and the second frame body 23 are rotated along the corresponding first virtual axis toward the side of A1 away from the flexible screen 30; at the same time, the transmission columns 2644 of the other two transmission members 264 are respectively in the corresponding toggle Sliding in the
