When the first side portion of the display screen 10 is in the unfolded state, the display area of the mobile terminal 10 increases. According to the technical scheme provided by the embodiment of the disclosure, the screen display area of the mobile terminal is increased on the basis that the mobile terminal is convenient to carry.
Alternatively, the first disc-shaped cam assembly 50 changes from the first state to the second state during deployment. As shown in fig. 1, the first state is a state in which the first side edge 51 of the first disc-shaped cam assembly 50 is attached to the inner wall of the first cam placing portion 21, and the second side edge 52 of the first disc-shaped cam assembly 50 is not attached to the back surface of the display screen 10; the second state is a state in which the second side edge 52 of the first disc-shaped cam assembly 50 is attached to the back surface of the display screen 10 and the first side edge 51 of the first disc-shaped cam assembly 50 is not attached to the inner wall of the first cam receiving portion 21.
It should be noted that when the first disc cam assembly is in the second state, the first disc cam assembly may also function to support the display screen.
Referring to fig. 1 and 2 in combination, during the retraction process, the first drive assembly 60 drives the first telescoping member 61 to pull the first disc-shaped cam assembly 50 inward, such that the first side housing 30 is retracted inward and the first side portion of the display screen 10 is retracted about the first roller 40.
Alternatively, with combined reference to fig. 1, during retraction, the first disc-shaped cam assembly 50 changes from the second state to the first state. The first state and the second state are already described above and will not be described herein again.

By the above manner, the first side shell 30 can be prevented from being excessively displaced, so that the screen is excessively stretched to cause damage.
The limiting mechanism can be a positioning pin, a positioning screw, a hall assembly and the like, and the embodiment of the disclosure does not limit the limiting mechanism.
In some exemplary embodiments, when the limiting mechanism is a positioning pin or a positioning screw, etc., the limiting mechanism may be disposed on the boss portion 22 of the support frame 20 to limit the first disc-shaped cam assembly 50 from continuing to rotate after being in the second state, so that the first side housing 30 cannot continue to move away from the support frame, and the first side portion of the display screen 10 will stop unfolding.
In other exemplary embodiments, the spacing mechanism may include a magnetic element and a hall sensor. The magnetic elements may include permanent magnetic elements and soft magnetic elements; a hall sensor is a magnetic field sensor made according to the hall effect. In the embodiment of the present disclosure, the hall sensor may indirectly measure the displacement between the magnetic element and the hall sensor, i.e., the displacement between the support frame 20 and the first side case 30. Alternatively, the magnetic element is provided on the support frame 20, and the hall sensor is provided on the first side case 30; alternatively, the magnetic element is provided on the first side case 30, and the hall sensor is provided on the support frame 20. When the displacement between the supporting frame 20 and the first side frame casing 30 is greater than the preset threshold, the mobile terminal controls the first driving assembly 60 to stop working, so that the first side frame casing 30 stops moving, and the first side portion of the display screen 10 stops unfolding.
