Abstract

A rotating mechanism includes a base, a first door plate, and a first connecting arm. Two axial ends of the base are a first end and a second end. Two ends of an extension direction of the first connecting arm are a first connecting end and a second connecting end. The first connecting end is connected to the base. The second connecting end is connected to the first door plate. The first connecting end and the base, and/or the second connecting end and the first door plate have a rotational degree of freedom therebetween. In a first direction, a distance between a center of the second connecting end and the first end is greater than a distance between a center of the first connecting end and the first end, where the first direction is parallel to a rotating axis of the first door plate.

First claim

a first connecting arm, wherein two ends of an extension direction of the first connecting arm are a first connecting end and a second connecting end, the first connecting end is connected to the base, the second connecting end is connected to the first door plate, and the first connecting end and the base have a rotational degree of freedom therebetween;
wherein in a first direction, a distance between a center of the second connecting end and the first end is greater than a distance between a center of the first connecting end and the first end, wherein the first direction is parallel to a rotating axis of the first door plate;
wherein in the first direction, a first distance is greater than a second distance; wherein the first distance is a minimum distance between the first end and a side wall of the second connecting end and facing to the first end, and the second distance is a minimum distance between the first end and a side wall of the first connecting end facing to the first end.

2. The rotating mechanism of claim 1 , wherein the first connecting arm further comprises a middle connecting section located between the first connecting end and the second connecting end; wherein in a second direction, the middle connecting section extends in a direction away from the first end, and wherein the second end is a direction that the base points to the first door plate.

3. The rotating mechanism of claim 2 , wherein in the second direction, the middle connecting section extends along a curve in the direction away from the first end.

4. The rotating mechanism of claim 2 , wherein in the second direction, the middle connecting section extends obliquely along a straight line in the direction away from the first end.

5. The rotating mechanism of claim 1 , wherein a first side wall of the first connecting end is flush with a second side wall of the second connecting end, the first side wall is away from the first end and the second side wall is away from the first end, and a width of the first connecting end is less than a width of the second connecting end.

6. The rotating mechanism of claim 1 , further comprising:
a second door plate, wherein the second door plate and the first door plate are respectively disposed on two opposite sides of the base; and
a second connecting arm, wherein the second connecting arm and the first connecting arm are spaced apart in an axial direction of the base, the second connecting arm is located on a side that is of the first connecting arm and that is away from the first end, two ends of an extension direction of the second connecting arm are a third connecting end and a fourth connecting end, the third connecting end is connected to the base, the fourth connecting end is connected to the second door plate, and the third connecting end and the base and/or the fourth connecting end and the second door plate have a rotational degree of freedom therebetween; and
in the first direction, a distance between a center of the fourth connecting end and the second end is greater than a distance between a center of the third connecting end and the second end.

7. The rotating mechanism of claim 6 , wherein in the first direction, a third distance is greater than a forth distance; wherein the third distance is a minimum distance between the first end and a side wall of the fourth connecting end and facing to the first end, and the forth distance is a minimum distance between the first end and a side wall of the first connecting end facing to the first end.

8. The rotating mechanism of claim 6 , wherein in the first direction, a fifth distance is greater than or equal to a sixth distance, wherein the fifth distance is a minimum distance between the first end and a side wall of the fourth connecting end and facing to the first end, and the sixth distance is a minimum distance between the first end and a side wall of the second connecting end facing away from the first end and the first end.

9. The rotating mechanism of claim 8 , wherein in the first direction, a seventh distance is greater than or equal to a eighth distance; wherein the seventh distance is a distance between a side wall that is of the first connecting end and that is away from the first end and a side wall that is of the third connecting end and that faces to the first end, and the eighth distance is a distance between the side wall that is of the second connecting end and that is away from the first end and the side wall that is of the fourth connecting end and that faces to the first end.

10. A support apparatus, wherein the support apparatus is configured to support a foldable screen, and the support apparatus comprises:
a rotating mechanism;
