Fig. 1 schematically shows an external view of an electronic device 100 according to an embodiment of the present disclosure.

As shown in fig. 1, the electronic device 100 may include a first body 1, a second body 2, and a hinge 10. The rotation shaft 10 connects the first body 1 and the second body 2.

According to the embodiment of the present disclosure, the hinge 10 may penetrate through a gap formed at opposite sides of the first body 1 and the second body 2 in a length direction of the gap, thereby allowing a hinge connection portion of the electronic device 100 to exhibit a smooth feeling of penetration.

The structure of the rotary shaft 10 will be described below by way of example with reference to fig. 2 to 8. Fig. 2 to 5 show an overall structure of the rotating shaft 10, and fig. 6 to 8 show partial views of the rotating shaft 10.

Fig. 2 schematically illustrates a perspective view of a spindle 10 according to an embodiment of the present disclosure. Fig. 3 schematically shows three views of the spindle 10 shown in fig. 2. Fig. 4A schematically shows a top view of the spindle 10 shown in fig. 2 in an unfolded state. Fig. 4B schematically illustrates an assembled view of the spindle 10 shown in fig. 2. Fig. 5 schematically shows an exploded view of the spindle 10 shown in fig. 2.

As shown in fig. 2 to 5, the rotating shaft 10 may include at least one hinge 14, at least two first struts 11, and at least one second strut 12.

The ends of the two movable parts of the hinge 14 may be connected with the first body 1 and the second body 2, respectively, and the hinge 14 is used for providing a torsion force when the first body and the second body are relatively rotated. Comparing fig. 2 and 4A, it can be seen that the hinge 14 comprises two movable parts that can be folded against each other. The hinge 14 may be any structure known in the art that provides rotational torque.

The ends of the two movable portions of the hinge 14 are respectively provided with a plurality of first mounting holes 141, and the hinge 14 can be mounted (for example, riveted) to the first body 1 and the second body 2 through the plurality of first mounting holes 141. When the hinge 10 is installed in the electronic device 10, the ends of the two movable portions of the hinge 14 will be hidden inside the first body 1 and the second body 2.

The first strut 11 is located between the ends of the two movable parts of each hinge 14. Wherein the hinge 14 spans the gap between the first body 1 and the second body 2, and the first strut 11 extends along the length of the gap. Wherein the first strut 11 is nested with the hinge 14. According to an embodiment of the present disclosure, the first rod 11 is provided with a through hole 112 for passing the hinge 14, so that the hinge 14 can pass through the first rod 11 and be sleeved on the first rod 11, which can be referred to the illustrations of fig. 4B to 6. Of course, in other embodiments, the first rod 11 is nested with the hinge 14, and a through hole through which the first rod 11 can pass may be reserved in the hinge 14, so as to penetrate the first rod 11 into the hinge 14.

The area of the first support bar 11 not in contact with the hinge 14 includes a concave structure, wherein the concave structures between two adjacent first support bars 11 combine to form an accommodating space 113 (refer to fig. 7), and the second support bar 12 is filled in the accommodating space 113. Reference may be made in particular to the detailed illustration of the cross-sectional view of fig. 7 below.

According to an embodiment of the present disclosure, the length of the first support bar 11 may be comparable to (e.g., equal to or close to) the length of the gap between the first body 1 and the second body 2 of the electronic device 100. The second supporting rod 12 is filled in the accommodating space 113 between two adjacent first supporting rods 11, and is used for limiting the movement of each first supporting rod 1 in the relative rotation process of the first body 1 and the second body 2 of the electronic device 100, so as to keep the stability and the beauty of the appearance structure of the rotating shaft 10.

According to some embodiments of the present disclosure, the shaft 10 may further include two third struts 13, wherein each third strut 13 may be connected with two movable portions of one hinge 14. For example, both ends of the third bar 13 may include lugs 131 (refer to fig. 4B and 5). The lug 131 may be provided with a coupling hole 1311. The two movable portions of the hinge 14 may further have second coupling holes 142 corresponding to the coupling holes 1311. The third bar 13 may be coupled to the hinge 14 by a coupling member (e.g., a bolt, or a rivet) passing through the coupling hole 1311 and the second coupling hole 142.

Meanwhile, two third struts 13 may be connected to the first body 1 and the second body 2, respectively. For example, the rod body middle portion of the third strut 13 may be further provided with a plurality of second mounting holes 132. The second mounting hole 132 may be used to connect the third bar 13 with one of the first body 1 and the second body 2. The two third struts 13 provide reinforcement for the mounting of the shaft 10 in the electronic device 100.

Fig. 6 schematically shows a front view and a right side view of the first bar 11 at a portion a in fig. 4B. In fig. 6, (a) is a front view in the viewing angle of fig. 4B, and (B) is a right view in the viewing angle of fig. 4B.

Referring to fig. 4B to 6, the first rod 11 includes a through hole 112 extending along a first direction i, wherein the first direction i is parallel to a line connecting ends of two movable portions of the hinge 14 when the hinge 14 is in the unfolded state. The through-hole 112 is sized to receive the hinge 14 therethrough. Thus, the hinge 14 can be nested on the first bar 11 through the through hole 112.

Fig. 7 schematically shows a cross-sectional view C-C in fig. 3. Fig. 8 schematically shows an enlarged plan view of the first strut at portion B in fig. 5.

Referring to fig. 4A-4B, and fig. 7, the shaft 10 further includes an FPC routing through hole 15. In the illustration of fig. 4A and 4B, the FPC routing through hole 15 is located in the area outlined by the dashed lines, passing through each first strut 11, each second strut 12 and each third strut. Two ends of the FPC routing through hole 15 point to the first body 1 and the second body 2, respectively. The FPC routing through holes 15 can be used for FPC routing. The FPC routing direction may be illustrated, for example, as the direction indicated by the arrow-headed line in fig. 7.

Referring to fig. 5, the first support bar 11 has a first through hole 151 formed therein for providing a trace of FPC. A second via hole 152 provided for the FPC wiring is formed in the second support bar 12, and a third via hole 153 provided for the FPC wiring is formed in the third support bar 13. The first through hole 151 may be a long and narrow through hole as shown in fig. 8. The second through hole 152 and the third through hole 153 are similar in shape to the first through hole 151.

With the arrangement of the first support rod 11, the second support rod 12 and the third support rod 13 in the rotating shaft 10, the first through hole 151 on each first support rod 11, the second through hole 152 on each second support rod 12 and the third through hole 153 on each third support rod 13 are sequentially butted and communicated with each other, so as to form an FPC routing through hole 15 (as shown in fig. 7) penetrating through the whole rotating shaft 10.

Referring to the illustrations of fig. 3 and 7, according to an embodiment of the present disclosure, a cross section of a portion of the shaft 10 including the concave structure in the first strut 11 may be dumbbell-shaped. The cross-section of the second strut 12 in the corresponding section may be oval. In fig. 7 it can be seen that the dumbbell-shaped structure in the first strut 11 is penetrated by the FPC routing through-hole 15 due to the presence of the FPC routing through-hole 15. The middle of the second support rod 12 is also penetrated by the FPC routing through hole 15.

According to the embodiment of the present disclosure, the dumbbell-shaped recessed structures of two adjacent first struts 11 may be combined to form an accommodating space 113, wherein the accommodating space 113 is filled with the second strut 12. In the process that the accommodating space 113 deforms along with the rotation of the first body 1 relative to the second body 2, the second support rod 12 can rotate along with the deformation of the accommodating space 113. During the rotation of the first body 1 relative to the second body 2, the outer profile of the second strut 12 is in rolling contact with the surfaces of the two first struts 11 forming the accommodation space 113. In this way, the second supporting rod 12 can support and limit the first supporting rod 11 during the rotation of the first body 1 of the electronic device 100 relative to the second body 2.

Meanwhile, according to the embodiment of the present disclosure, the size of the second pole 12 in the direction opposite to the gap of the accommodating space 113 is always larger than the size of the gap of the accommodating space 113 regardless of the relative rotation of the first body 1 and the second body 2 to any position. In this way, it can be ensured that the second support rod 12 does not slip out of the accommodating space 113 during the rotation of the first body 1 of the electronic device 100 relative to the second body 2, and thus the stability of the whole structure of the rotating shaft 10 can be ensured.

According to embodiments of the present disclosure, the material of the first strut 11, and/or the second strut 12, and/or the third strut 13 may be a liquid alloy, or aircraft aluminum.

Those skilled in the art will appreciate that various combinations and/or combinations of features recited in the various embodiments and/or claims of the disclosure can be made without conflict, even if such combinations or combinations are not expressly recited in the present disclosure. In particular, various combinations and/or combinations of the features recited in the various embodiments and/or claims of the present disclosure may be made without departing from the spirit or teaching of the present disclosure.
