[0159] It should be added that Figure 6 The utility model is a foldable electronic device Figure 3 A cross-sectional schematic diagram of the A-A' section line, wherein the first outer rotation axis OA1, the second outer rotation axis OA2, the first tail pivot axis TP1, the second tail pivot axis TP2, the first inner virtual axis V1, the second inner virtual axis V2, the first outer virtual axis OV1, the first head pivot axis HP1, the second outer virtual axis OV2, the second head pivot axis HP2, the first axis L1 and the second axis L2 are substantially parallel to each other.

[0160] See below for details Figure 8 , Fig. 9 and Fig.10 To illustrate the operation of the foldable electronic device 1000 of the present invention. Figure 8 ), the flexible screen 5 is flattened, the base portion 11, the first panel body 23, the second panel body 33, the first water drop plate 25 and the second water drop plate 35 jointly support the flexible screen 5, the first water drop plate 25 relative to the second water drop plate 35, the first panel body 23 relative to the second panel body 33, the first carrier 221 relative to the second carrier 321 are all clamped at about 180 degrees, the first sliding wing plate 433 of the first crank rod 43 is clamped at about 160 degrees relative to the second sliding wing plate 443 of the second crank rod 44, and the first wing member 21 is clamped at about 210 degrees relative to the second wing member 31 (refer to Figure 6 In addition, the lifting block 42 is relatively farthest from the flat plate portion 12 , the first sliding pins 47 are respectively located at the first open end 4511 of the first yoke slot 451 , and the second sliding pins 48 are respectively located at the second open end 4611 of the second yoke slot 461 .

[0161] From the expanded state to the half-open state ( Fig. 9) is transformed, the first wing 21 and the second wing 31 are pivoted relative to the seat body 11 with the first inner virtual axis V1 and the second inner virtual axis V2 as the center, so that the first tail pivot portion 213 and the second tail pivot portion 313 are gradually approached to each other, the first supporting member 22 and the second supporting member 32 are pivoted relative to the first wing 21 and the second wing 31 with the first outer rotation axis OA1 and the second outer rotation axis OA2 as the center, and the first supporting member 22 and the second supporting member 32 are pivoted relative to the first water drop plate 25 and the second water drop plate 35 with the first outer virtual axis OV1 and the second outer virtual axis OV2 as the center, the first connecting rod 24 and the second connecting rod 34 are also pivoted relative to the first wing 21 and the second wing 31 with the first tail pivot axis TP1 and the second tail pivot axis TP2 as the center, and the first connecting rod 24 and the second connecting rod 34 are pivoted relative to the first water drop plate 25 and the second water drop plate 35 with the first head pivot axis HP 1 and the second head pivot axis HP2 as the center, that is, from the state where the upper surfaces of the first water drop plate 25, the upper surfaces of the second water drop plate 35 and the upper surface of the seat body 11 are coplanar, it gradually becomes that the first water drop plate 25 and the second water drop plate 35 are obliquely intersecting with the seat body 11 respectively, at this time, the first sliding wing plate 433 and the second sliding wing plate 443 are linearly slid in the first straight groove 224 and the second straight groove 324 respectively (sliding from one end of the straight groove to the other end), the first main rod shaft 431 and the second main rod shaft 441 are respectively pivoted in opposite directions with the first axis L1 and the second axis L2 as the center, and at the same time, the lifting block 42 approaches the flat plate portion 12 along the guide column 41 (i.e., parallel to the thickness direction Z). Since the lifting block 42 moves to simultaneously drive the first sliding pin 47 in the first sliding yoke 45 and the second sliding pin 48 in the second sliding yoke 46, the first main rod shaft 431 and the second main rod shaft 441 can be pivoted in opposite directions synchronously. At this time, the first sliding pin 47 moves from the first open end 4511 of the first yoke groove 451 to the first closed bottom end 4512 (i.e. moves inward), and the second sliding pin 48 moves from the second open end 4611 of the second yoke groove 461 to the second closed bottom end 4612 (i.e. moves inward).

[0162] In half-open state ( Fig. 9 ), the first panel body 23 is relative to the second panel body 33, the first carrier 221 is relative to the second carrier 321, and the first sliding wing 433 of the first crank rod 43 is relative to the second sliding wing 443 of the second crank rod 44 are all sandwiched at about 90 degrees, the angle between the first water drop plate 25 and the second water drop plate 35 becomes smaller, and the angle between the first wing 21 and the second wing 31 also becomes smaller. In addition, the center of the lifting block 42 is approximately at the half height position of the guide column 41, the first sliding pin 47 is respectively located at the first closed bottom end 4512 adjacent to the first yoke groove 451, and the second sliding pin 48 is respectively located at the second closed bottom end 4612 adjacent to the second yoke groove 461.

[0163] From half-open state to folded state ( Fig.10 ) changes, the first rear pivot 213 and the second rear pivot 313 are closer to each other, the first panel body 23 relative to the second panel body 33, the first carrier 221 relative to the second carrier 321, and the first wing 21 relative to the second wing 31 gradually become roughly parallel to each other, and the angle between the first water drop plate 25 and the second water drop plate 35 and the angle between the first sliding wing plate 433 and the second sliding wing plate 443 gradually become smaller, or even become a relatively negative angle. At this time, the lifting block 42 is closer to the flat plate 12 along the thickness direction Z parallel to the guide column 41, but the first sliding pin 47 returns to the first open end 4511 of the first yoke slot 451 (i.e. moves outward), and the second sliding pin 48 returns to the second open end 4611 of the second yoke slot 461 (i.e. moves outward).

[0164] In the folded state ( Fig.10 ), the first water drop plate 25 and the second water drop plate 35 intersect at about -30 degrees (that is, the interval near the seat body 11 is larger, and the interval away from the seat body 11 is smaller, such as Fig.11 As shown in the figure, the first sliding wing plate 433 intersects the second sliding wing plate 443 by about -30 degrees, the first panel body 23 intersects the second panel body 33, the first carrier 221 intersects the second carrier 321, and the first wing member 21 intersects the second wing member 31 by about 0 degrees (parallel to each other). At this time, the lifting block 42 is closest to or even against the flat plate portion 12, the first sliding pin 47 is respectively located at the first open end 4511 of the first yoke slot 451, and the second sliding pin 48 is respectively located at the second open end 4611 of the second yoke slot 461.

[0165] Specifically, the Scotch yoke synchronization module 4 has two groups of Scotch yoke mechanisms, the first group is composed of a guide column 41, a lifting block 42, a first crank rod 43, a first sliding yoke 45 and two first sliding pins 47, and the second group is composed of a guide column 41, a lifting block 42, a second crank rod 44, a second sliding yoke 46 and two second sliding pins 48; wherein, since the guide column 41 and the lifting block 42 are shared, the first sliding pin 47 is integrally formed on the first main rod body 431 of the first crank rod 43, and the second sliding pin 48 is integrally formed on the second main rod body 441 of the second crank rod 44, so the two groups of Scotch yoke mechanisms will be synchronized when the linear motion is converted into the rotational motion, and conversely, the rotational motion is also synchronized when it is converted into the linear motion. Therefore, when changing from the expanded state to the folded state, even if only the first panel assembly 2 is pulled and pivoted relative to the central base 1, the first main rod body 431 pivots around the first axis L1, driving the first sliding pin 47 to perform linear motion in the first sliding yoke 45, so that the lifting block 42 approaches the flat plate portion 12, thereby synchronously driving the second sliding pin 48 to perform linear motion in the second sliding yoke 46, and causing the second main rod body 441 to pivot (reverse pivot) around the second axis L2, causing the second panel assembly 3 to be able to synchronously pivot relative to the central base 1; similarly, if only the second panel assembly 3 is pulled, the first panel assembly 2 will also pivot synchronously, and if it is changed from the folded state to the expanded state, it will also be synchronous, and the relevant details will not be repeated.

[0166] In this embodiment, a first sliding yoke 45 is used with two first sliding pins 47, and a second sliding yoke 46 is used with two second sliding pins 48, but it can also be a first sliding yoke 45 with a first sliding pin 47 or a second sliding yoke 46 with a second sliding pin 48, and the number can also be multiple sets. In addition, the first sliding yoke 45 and the second sliding yoke 46 can also be changed from an open type to a closed type. In addition, the height of the guide column 41 in the thickness direction Z is greater than the thickness of the lifting block 42, but the height of the guide column 41 can also be appropriately reduced (for example, approximately the same as the thickness of the lifting block 42) to avoid interference with the flexible screen 5.

[0167] From a mechanical point of view, the utility model uses two groups of six-link mechanisms, the first group is the base 11, the first wing 21, the first bearing member 22, the first connecting rod 24, the first water drop plate 25 and the first crank rod 43, and the second group is the base 11, the second wing 31, the second bearing member 32, the second connecting rod 34, the second water drop plate 35 and the second crank rod 44. Therefore, when in the folded state, because the first water drop plate 25 and the second water drop plate 35 intersect at -30 degrees, the bendable area 51 of the flexible screen 5 is bent, and the first wing 21, the second wing 31, the first water drop plate 25, the second water drop plate 35 and the base 11 of the central base 1 jointly define an accommodating space S to accommodate the bendable area 51, and the accommodating space S has a water drop-shaped cross-section (such as Fig.11 ).

[0168] One additional explanation is that since the first sliding pin 47 is respectively formed at the two ends of the first inwardly extending wing 434, that is, the whole is T-shaped, and the first inwardly extending wing 434 corresponds to the first central concave area 452, and the first sliding pin 47 corresponds to the first outer convex area 453, during the rotation process, the first inwardly extending wing 434 will not collide or interfere with the first sliding yoke 45, and the first sliding pin 47 can slide smoothly in the first yoke groove 451; and the second sliding pin 48 is respectively formed at the two ends of the second inwardly extending wing 444, also in a T-shape as a whole, and the second inwardly extending wing 444 corresponds to the second central concave area 462, and the second sliding pin 48 corresponds to the second outer convex area 463, therefore, during the rotation process, the second inwardly extending wing 444 will not collide or interfere with the second sliding yoke 46, and the second sliding pin 48 can slide smoothly in the second yoke groove 461.

[0169] Please refer to Fig.12 , which is another embodiment of the utility model. The main difference from the previous embodiment is that this embodiment uses two sets of four-bar linkages. Since the four-bar linkage has two fewer links than the six-bar linkage, the first link 24, the first water drop plate 25, the second link 34 and the second water drop plate 35 in the previous embodiment are omitted in this embodiment, and the rest of the parts are the same as the previous embodiment, that is, the two sets of Scotch yoke mechanisms of the Scotch yoke synchronization module 4 are still retained, so the synchronization effect can still be achieved. However, since the first water drop plate 25 and the second water drop plate 35 are omitted in this embodiment, when in the folded state, a accommodating space S is defined that is not in the shape of a water drop, but in a space with a U-shaped cross section; in addition, the support force of the omitted first water drop plate 25 and the second water drop plate 35 can be compensated by adding other support plates (for example, resting on the seat body 11), which will not be repeated here.

[0170] In summary, the foldable electronic device of the utility model uses two sets of Scotch yoke mechanisms of the Scotch yoke synchronization module to enable the linear motion to be converted into rotational motion synchronously, and the rotational motion to be converted into linear motion synchronously. Therefore, the first panel assembly and the second panel assembly are ensured to reach the predetermined position at the same time, thereby enabling the opening or folding of the foldable electronic device to be synchronous and complete.
