Foldable mobile terminal, foldable mechanism for foldable mobile terminal, and foldable unit for foldable mobile terminal

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:

• a first rotation assembly, capable of being at least partially received in the first shell and able to slide towards or away from the first shell;
• a second rotation assembly, capable of being at least partially received in the second shell and able to slide towards or away from the second shell;
• and
• a joining sheet and two pressing elements, wherein the joining sheet crosses over the first rotation assembly and the second rotation assembly and defines a first hole in a first end of the joining sheet and a second hole in a second end of the joining sheet opposite to the first end;
• one of the two pressing elements is arranged to extend through the first hole to be capable of being fixedly connected to the first shell and is slidable in the first hole;
• the other of the two pressing elements is arranged to extend through the second hole to be capable of being fixedly connected to the second shell and is slidable in the second hole;
• wherein when the first rotation assembly moves towards or away from the first shell and the second rotation assembly moves towards or away from the second shell, the joining sheet moves with respect to the two pressing elements along a direction towards which the first hole and the second hole elongate.
