21, 22, 23, 24, 25, the

1 including a plurality of sliders rotatably connected in turn, the plurality of sliders comprise a first fixed

11 positioned at the head end, a second

12 positioned at the tail end and a plurality of rotating

13, 14, 15, 16 and 17 positioned in the middle, the

21, 22, 23, 24 and 25 correspond to the rotating

13, 14, 15, 16 and 17 one by one, each

21, 22, 23, 24 and 25 comprises an inner supporting

31 and an

32, two ends of the inner supporting

31 are respectively connected with two ends of the

32, each rotating slider is positioned in the

32 of the shell corresponding to the rotating slider and connected with the inner supporting

31 of the shell, the inner supporting

31 is used for supporting the

100, and the

32 is used for shielding and protecting the

1.

Through the technical scheme, when the

100 is folded and bent, the rotating sliding

13, 14, 15, 16 and 17 rotate relative to the first

11 and the second

12, and because the shell is in one-to-one correspondence with the rotating sliding blocks and connected with each other, the rotating sliding blocks can drive the shell to move in the rotating process, so that the inner supporting

31 on the shell moves along with the bending of the

100, and the inner supporting

31 is ensured to support the

100. Therefore, no matter the

100 is at any angle in the folding process, when the user clicks the

100, the bending part of the

100 can be well supported, the touch feeling of any region can be guaranteed, the user experience can be improved, and the

100 is protected. In addition, since the

200 is covered by the

32, it is possible to prevent the normal operation of the

1 from being affected by the entrance of dust, foreign matter, etc. into the

200, thereby protecting the

1.

13, 14, 15, 16, 17 may be parallel to each other and located on the inner surface of the

100. The rotation axes are parallel to each other, so that the arrangement of the sliders is facilitated, and the rotation axis of each

13, 14, 15, 16, 17 is located on the inner surface of the

100, so that on one hand, the

100 can be always attached to the inner side surface of the

31 corresponding to each rotation slider in the folding and bending process, and the

100 is not subjected to the action of tensile stress in the folding, bending and flattening processes, and the service life of the

100 is prolonged; on the other hand, the rotating slider has a smaller turning radius, which is beneficial to reducing the overall size of the

1.

In addition, as shown in fig. 2 and 3, in order to form a reliable connection to the terminal body and to support the

100 well, the

200 may include two or

1 spaced apart in the width direction of the

100, and each housing is connected to the two or

1 at the same time. Wherein the number of

1 may be determined according to practical situations, for example, according to the width dimensions of the terminal body and the

100, which is not limited by the present disclosure. In one embodiment, as shown in fig. 3, the number of the

1 is two, and the hinges are symmetrically arranged on two sides of the

100 in the width direction, so as to have a reliable connection and support effect.

31 is connected to one

322, the other end of the

31 is connected to the

322, two or

1 are located between the two

322, and the rotary slider is located between the

31 and the

321, i.e., the rotary slider is located between the

31 and the

321 of the corresponding housing, so as to prevent the

13, 14, 15, 16, 17 from being exposed.

The

321 may be a curved strip or a planar strip, and the

322 may be a sector or an isosceles triangle, so that when the

100 is folded or unfolded, the adjacent housings can be conveniently folded or unfolded.

As shown in fig. 1, when the

100 is unfolded, the

32 of the plurality of

21, 22, 23, 24, 25 are nested with each other to be folded together, and the

31 of the plurality of

21, 22, 23, 24, 25 are distributed along the length direction of the

100; as shown in fig. 4 and 5, when the

100 is folded, the

16, and the fifth

17 and the second fixed

12 are rotatably connected, and the third

15 is located at the middle position and connected with the second

14 and the fourth

16.

21, the

22, the

23, the

24, and the

25, and are respectively mounted to the first

13, the second

14, the third

15, the fourth

16, and the fifth

17. Thus, when the

100 is unfolded, as shown in fig. 1, the outer covers 32 of the remaining housings are all folded within the

32 of the most central housing, i.e., the

21, the

22, the

24, and the

25 are all housed within the

32 of the

1 may have an even number of rotating sliders as long as the folding and unfolding of the

100 is possible.

In addition, in order to ensure that the adjacent sliders of the

1 can smoothly slide relative to each other and can limit the angle of rotation between the adjacent sliders, in the

200 provided by the present disclosure, a kinematic pair and an angle limiting structure are formed between the adjacent sliders.

54, the first

51 and the second

53 cooperate to form a revolute pair of the two adjacent sliders, and the first stopping

52 and the second stopping

54 cooperate to limit the rotation angle between the two adjacent sliders. Thus, by limiting the rotation angle of each sliding block, when the

1 is in the unfolding state, the inner supporting

31 of each shell can be on the same plane, and a flexible screen supporting plane with better flatness can be formed. As shown in fig. 1, the heights of the inner support bars 31 of the first, second, third, fourth and

21, 22, 23, 24 and 25 are flush.

50 is formed with a first

51 and a first stopping

52 on both side walls, the first

13 is formed with a

60 engaged with the protruding

50, and the

60 is formed with a second

53 and a second stopping

54 on both side walls. When the

100 is unfolded to be flat, the

52 and the

54 are attached to limit the

100 from being folded further; when the

100 is folded, as shown in fig. 8, the first fixed

11 is rotated counterclockwise so that the first

51 slides on the second

53, thereby achieving the bending folding of the

100. In other embodiments, the first

51 and the first stopping

52 may be formed on the first

13, and the second

53 and the second stopping

54 may be formed on the first fixed

91 is formed on one of the two adjacent sliders, and a limiting

92 is formed on the other of the two adjacent sliders, and the limiting

92 is slidably fitted in the limiting arc-shaped

55, the arc-shaped

55 is provided on one of the adjacent two sliders, and the

6 passes through the arc-shaped

55 to be connected to the other of the adjacent two sliders. Thus, the adjusting

6 is used as a connecting piece for connecting the adjacent sliding blocks and an adjusting piece for adjusting the friction force between the two adjacent sliding blocks, and the friction force between the two adjacent sliding blocks can be adjusted by increasing or reducing the pretightening force of the adjusting

6.

8 are respectively inserted into the elastic

57 on the two sliders, and optionally, the

8 is interference-fitted in the elastic

57 to prevent the

8 from being accidentally dropped from the elastic

57.

For example, the axes of the two elastic

57 on the first

13 and the second

14 are offset by 1mm, and the axes of the two elastic

57 on the second

14 and the third

15 are offset by 2mm, so that the frictional force between the second
