Referring to FIG. 6, FIG. 8, FIG. 17, and FIG. 18, the skeleton structure 5 is disposed on the hinge mechanisms 3 and the connecting pipe 4 along the front-rear direction D2. In detail, the framework structure 5 includes a first steel bar 51, two steel plates 52, two second steel bars 53, and two connecting plates 54. The first steel bar 51 extends along the front-rear direction D2 and covers the connecting tube 4 and the shaft caps 37, and is locked to the first fixing holes 371 and the shafts by four locking members (not shown). The second fixing hole 41 is relatively fixed to the connecting pipe 4 and the shaft caps 37.

In this embodiment, the second steel bars 53 are not directly connected to the first steel bar 51 or the steel plates 52, but are embedded in the soft layer of the framework structure 5 by using injection molding ( (Not shown), the first steel bar 51, the steel plates 52, the second steel bars 53 and the connecting plates 54 are embedded by the soft layer to relatively fix the positions of the second steel bars 53. In this embodiment, the material of the soft layer is rubber. The skeletal structure 5 is located under the shell plate 12, so that the shell plate 12 is constantly supported by the skeletal structure 5 during the rotation of the casings 11, so as to stably support the flexible screen.

The baffles 6 extend along the front-rear direction D2 and are located on the left and right sides of the connecting pipe 4, each baffle 6 is connected to the lower surface 3612 of the rotating plates 361 of the linkage units 36 on the same side, and the The isolator 6 is located between the casings 11 when the casings 11 are in the flattened position and is exposed on the folding surface 112a.

Referring to FIG. 1, FIG. 6, FIG. 10, and FIG. 17, when the casings 11 are located at the flattened position, the joint surface 14 is flattened, and the skeleton structure 5 also abuts the shell plate in a flattened state. 12; the linkage units 36 of each hinge mechanism 3 are located on the same horizontal plane, the connection unit 35 extends in a straight line along the left and right direction D1, the synchronization member 33 is close to the pipe seat 31, and the rotation plate 361 of each linkage unit 36 The first outer side 3613 is aligned with the second outer side 364b of the transmission plate 364; see also FIG. 19 and FIG. 20, the link portion 363a of the linkage 363 abuts on one of the radial sides of the fan-shaped groove 3615. 3615b, the second guide portion 363d is located at the expanded end portion 3618 of the arc-shaped hole 3617.

Referring to FIGS. 21 to 25, when the casings 11 are forced to rotate and fold from the flattened position to the folded position along the bending direction B1, each rotating plate 361 of each hinge mechanism 3 is corresponding to the corresponding one. The transmission shaft 32 rotates around the axis. Each connection end 351 and each transmission plate 364 of the connection unit 35 rotate around the first axis L1. Therefore, during the rotation, the rotation plate 361, the transmission The plate 364, the linkage 363, the driven seat 365, and the casing 11 will synchronously move relative to each other until the casings 11 rotate to the folded position. In detail, since the first axis L1 is located above the transmission shafts 32, the distance between the first outer side 3613 of each rotating plate 361 and the first axis L1 will follow the rotating plate 361. As the rotation angle of the transmission plate 364 increases, the arc length of the second outer side 364b of the transmission plate 364 and the first axis L1 and the total length of the transmission plate 364 remain unchanged. Relative movement occurs, so that the first outer side 3613 and the second outer side 364b, which were originally aligned with each other, are relatively moved by a first predetermined distance d1 because of the relative movement of the transmission plate 364 and the rotation plate 361, and are located at the same time The first guide portion 363c of the linkage 363 between the transmission plate 364 and the rotation plate 361 is also driven by the transmission plate 364 to move the first predetermined distance d1 in the direction of the first axis L1, and the second guide At the same time, the lead portion 363d moves along the arc-shaped hole 3617 from the expanded end portion 3618 to the folded end portion 3619 for a second predetermined distance d2. It should be noted that the first predetermined distance d1 and the second predetermined distance d2 are displacements parallel to the extending direction of the guide plate portions 361c and the track holes 3614, and since the first guide portion 363c and The second guide portion 363d all moves with the rotating shaft portion 363b as an axis. Therefore, the actual movement amount of the first guide portion 363c must be combined to calculate the displacement of the elliptical transmission hole 364c moving in the front-rear direction D2. Amount, the actual moving amount of the second guide portion 363d must also be combined to calculate the displacement amount moving in the elliptical driven hole 365c along the front-rear direction D2. The first predetermined distance d1 is proportional to the second predetermined distance d2, and the second predetermined distance d2 is greater than the first predetermined distance d1. Therefore, the second guide portion 363d simultaneously drives the driven seat 365 to be connected. In the process of the casing 11 moving the second predetermined distance d2 in the direction of the corresponding transmission shaft 32, not only the internal and external diameter difference between the joint surface 14 and the collapsed surface 112a can be overcome, and the casing plate 12 During the bending process, it will not be pulled in the left and right direction D1, and the hinge mechanism 3 and the skeleton structure 5 are linked by the casing 11 and are connected with the casing plate 12 during the rotation of the casings 11 Keep the same distance between them to support the shell plate 12 constantly.

Referring to FIGS. 3 to 5 and FIGS. 26 to 29, when the casings 11 are rotated to the folded position, a portion of the joint surface 14 located on the first casing 11 a and a portion of the engaging plate 13 are back-to-back. In appearance, the shell plate 12 is bent into a curved shape, and is constantly supported by the skeleton structure 5 to stably support the center of the flexible screen. The connecting unit 35 is curved along the surface of the connecting plate portion 311 and the rotating plate 361 of the socket 31, the synchronization member 33 is far from the socket 31, and the first outer side 3613 of the rotating plate 361 of each linkage unit 36 and The second outer side 364b of the transmission plate 364 is spaced apart from the first predetermined distance d1 ', the link portion 363a of the linkage 363 abuts against the other radius side 3615b of the fan-shaped groove 3615 and the second guide 363d is located at the folded end 3619 of the arc-shaped hole 3617.

6 and FIG. 7 again, since the carrier plate 13 is relatively fixed by being connected to the first casing 11a and the casing plate 12 through the flexible screen, the first casing 11a and the casing plate 12 are in contact with each other. The second casing 11b is relatively fixed by the hinge mechanisms 3. Therefore, during normal rotation of the casings 11, the carrier plate 13 and the second casing 11a will not cause relative movement, and the cushioning The block 21 is held at the normal end portions 1141 of the buffer grooves 114d. However, when the hinge mechanism 3 is unable to move the second predetermined distance d2 smoothly due to manufacturing tolerances, man-made assembly errors, or other defects, the movement amount of the casings 11 may not be sufficient for the second predetermined distance d2 (see FIG. 25). Since one end of the flexible screen is fixedly connected to the first casing 11a, when the casing 11 is insufficiently moved during the rotation, the other end of the flexible screen is connected to the carrying plate 13, the buffers Block 21, the interlocking blocks 22 and the second casing 11b are relatively moved to prevent the flexible screen from being damaged by joint pulling of the casings 11. During the relative movement, the buffer blocks 21 are relatively moved from the normal end portion 1141 to the buffer end portion 1142, and the linkage blocks 22 are relatively moved in a direction away from the limit holes 114f. The elastic members 23 will simultaneously enable the second casing 11b to move to the second predetermined distance d2 by the reaction force of the elastic expansion force, and cause the buffer blocks 21 to move back to the normal ends 1141. The linkage block 22 is moved back to the limiting holes 114f and restored to the normal positions of the casings 11 in the folded position. In a changed embodiment, the second casing 11b and the screen protection module 2 are not limited to the outer-folding screen device 100 installed in this embodiment, and may also be connected to other aspects of the hinge, hinge device, and casing. Assemble and use each other.

In summary, by designing the synchronizing lever portion 322 on the transmission shafts 32 to cooperate with the synchronization member 33, the new outer folding screen device 100 can synchronize the rotation of the transmission shafts 32 and increase the hinge mechanism. 3 The stability during rotation prevents the two casings 11 from pivoting at different angles to prevent damage to the screen. In addition, during the rotation of the casings 11 from the flattened position to the folded position, due to the rotating plate 361, The corresponding transmission shaft 32 rotates around the axis, and the transmission plate 364 rotates around the first axis L1 above the transmission shaft 32 as the center of rotation, which causes a difference between the inner and outer diameters of the transmission plate 364 and the rotation plate 361, that is, the transmission The plate 364 moves a first predetermined distance d1 relative to the rotating plate 361, and the design of the fan-shaped groove 3615 and the transmission member enables the second guide portion 363d of the transmission member to move a first distance d1 larger than the first predetermined distance d1. At two predetermined distances d2, the driven casing 11 should be moved in the direction of the corresponding transmission shaft 32 to compensate for the risk of screen damage caused by the difference between the inner and outer diameters, so it can indeed achieve the purpose of new cost.

However, the above are only examples of the new model. When the scope of implementation of the new model cannot be limited by this, any simple equivalent changes and modifications made in accordance with the scope of the patent application of the new model and the content of the patent specification are still Within the scope of this new patent.
