As shown in fig. 1-3, the hinge mechanism includes a connecting base 820 and a plurality of support bars 810, the plurality of support bars 810 being arranged side by side. Specifically, the number of the supporting bars 810 may be two, three, or more, and the sizes of the plurality of supporting bars 810 may be the same, so that the bending degrees at the positions of the hinge mechanism are substantially the same in the bending process, and in the case that the display screen of the electronic device is a flexible screen, the supported effect at the positions in the area of the display screen, which is matched with the hinge mechanism, is substantially the same, and it is ensured that the supported effect of the display screen is good.

Optionally, the number of the support bars 810 is odd and larger than 3, in this case, the support bar positioned at the center among the plurality of support bars 810 may serve as the rotation axis of the whole hinge mechanism during the rotational deformation of the hinge mechanism, so that the rotation form of the hinge mechanism is more symmetrical, and the support effect of the hinge mechanism is further improved. Particularly, the supporting bar located at the middle of the supporting bars 810 can be a fixing supporting bar, the supporting bars on the two sides of the fixing supporting bar back to back can be rotating supporting bars, and the two sides of the fixing supporting bar back to back are respectively provided with the rotating supporting bars with the same number. In addition, in the case that the number of the support bars 810 is large, the rotation angle of each support bar 810 can be relatively small, so that the bending uniformity of the hinge mechanism is stronger.

As shown in fig. 1 and 2, two adjacent support bars 810 are rotatably connected by a connection seat 820, specifically, the connection seat 820 may be a hinge, which is fixedly connected with the two support bars 810 to enable the two support bars 810 to rotate relatively, the connection seat 820 and the support bars 810 may be connected to each other by bonding, welding, or connecting members, and the connection between the connection seat 820 and the support bars 810 may include overlapping or sleeving. More specifically, two adjacent support bars 810 may be connected by one connecting seat 820, the connecting seat 820 may be disposed in the middle of the length direction of the support bar 810, or the two support bars 810 may also be connected by a plurality of connecting seats 820, the plurality of connecting seats 820 may be spaced apart along the length direction of the support bar 810, which may improve the connection reliability between the two support bars 810.

In the process of connecting the two support portions 410 by the hinge mechanism, the support bar 810 positioned on the first side of the hinge mechanism is connected with one support portion 410, the support bar 810 positioned on the second side of the hinge mechanism is connected with the other support portion 410, and the first side and the second side are opposite sides of the hinge mechanism. Specifically, the supporting bar 810 and the supporting portion 410 may be connected together by means of bonding, connecting member connection, or the like. More specifically, the supporting bars 810 and the supporting portion 410 may be directly connected or indirectly connected through other structures to meet different requirements.
