Abstract

A foldable mobile terminal and related products include: a flexible display screen; a housing assembly including a first housing and a second housing, the flexible display screen being provided on the first housing and the second housing; a first rotating assembly that is at least partially received in the first housing and can extend or retract with respect to the first housing in a sliding manner, the first rotating assembly being provided with a first groove; a second rotating assembly that is at least partially received in the second housing and can extend or retract with respect to the second housing in a sliding manner; and a first roller and a first spring provided between the first rotating assembly and the first housing.

First claim

What is claimed is:

1. A foldable mobile terminal, comprising:
a flexible display screen;
a shell assembly, comprising a first shell and a second shell, wherein the flexible display screen is arranged on the first shell and the second shell;
a first rotation assembly, comprising:
a first sliding plate, at least partially received in the first shell and able to slide towards or away from the first shell;
a first rotation shaft, arranged on the first sliding plate;
a first elastic sheet, arranged on the first sliding plate, wherein the first elastic sheet comprises two first engaging portions; and
a first connection rod, wherein a first end of the first connection rod is slidably hinged to the first rotation shaft, a second end of the first connection rod is rotatably connected to the first shell, and the two first engaging portions correspond to two extreme positions of the first end of the first connection rod in a sliding direction of the first end of the first connection rod; and

a second rotation assembly, comprising:
a second sliding plate, at least partially received in the second shell and able to slide towards or away from the second shell;
a second rotation shaft, arranged on the second sliding plate; and
a second connection rod, wherein a first end of the second connection rod is slidably hinged to the second rotation shaft, and a second end of the second connection rod is rotatably connected to the second shell.

2. The foldable mobile terminal according to claim 1 , wherein the second rotation assembly further comprises a second elastic sheet, the second elastic sheet is arranged on the second sliding plate, and the second elastic sheet comprises two second engaging portions corresponding to two extreme positions of the first end of the second connection rod in a sliding direction of the first end of the second connection rod.

3. The foldable mobile terminal according to claim 2 , wherein the first elastic sheet further comprises a first damping portion arranged between the two first engaging portions; and the first damping portion has a first gap configured for the first end of the first connection rod to extend though, each of the two first engaging portions has a second gap configured for the first end of the first connection rod to extend through, and the first gap is smaller than the second gap.

4. The foldable mobile terminal according to claim 2 , wherein the second elastic sheet further comprises a second damping portion arranged between the two second engaging portions;
and the second damping portion has a third gap configured for the first end of the first connection rod to extend though, each of the two first engaging portions has a fourth gap configured for the first end of the first connection rod to extend through, and the third gap is smaller than the fourth gap.

5. The foldable mobile terminal according to claim 2 , wherein
the first rotation assembly further comprises a first sliding member, the first sliding member slidably sleeves on the first rotation shaft, and the first end of the first connection rod is rotatably connected to the first sliding member; and
the second rotation assembly further comprises a second sliding member, the second sliding member slidably sleeves on the second rotation shaft, and the first end of the second connection rod is rotatably connected to the second sliding member.

6. The foldable mobile terminal according to claim 5 , wherein
the first rotation assembly further comprises a first support connected to the first sliding plate, the first rotation shaft is arranged on the first support, and the first sliding member is arranged between the first support and the first sliding plate; and
the second rotation assembly further comprises a second support connected to the second sliding plate, the second rotation shaft is arranged on the second support, and the second sliding member is arranged between the second support and the second sliding plate.

7. The foldable mobile terminal according to claim 6 , further comprising a linkage element, wherein the first rotation shaft and the second rotation shaft are arranged to extend through the linkage element, and the first sliding member and the second sliding member are arranged to move synchronously by using the linkage element.

8. The foldable mobile terminal according to claim 6 , wherein the first support has a first receiving cavity, and the first elastic sheet is received in the first receiving cavity.

9. The foldable mobile terminal according to claim 8 , wherein the first receiving cavity comprises two first positioning cavities and a first releasing cavity between the two first positioning cavities, each of the two first positioning cavities corresponds to a corresponding one of the two first engaging portions of the first elastic sheet, and a portion of the first elastic sheet is arranged between the two first engaging portions, disposed in the first releasing cavity, and able to be elastically deformed.

10. The foldable mobile terminal according to claim 8 , wherein the first elastic sheet is stadium-shaped having an opening at an end and closed at an opposing end, or the first elastic sheet comprises two separated strips.

11. The foldable mobile terminal according to claim 6 , wherein the second support has a second receiving cavity, and the second elastic sheet is received in the second receiving cavity.

12. The foldable mobile terminal according to claim 11 , wherein the second receiving cavity comprises two second positioning cavities and a second releasing cavity between the two second positioning cavities, each of the two second positioning cavities corresponds to a corresponding one of the two second engaging portions of the second elastic sheet, and a portion of the second elastic sheet is arranged between the two second engaging portions, disposed in the second releasing cavity, and able to be elastically deformed.

13. The foldable mobile terminal according to claim 11 , wherein the second elastic sheet is stadium-shaped having an opening at an end and closed at an opposing end, or the second elastic sheet comprises two separated strips.

14. A foldable mechanism for a foldable mobile terminal, the foldable mobile terminal comprising a first shell and a second shell connected to each other, the foldable mechanism comprising:
