The length direction of the electronic device 100 is a first direction, the width direction is a second direction, and the thickness direction is a third direction. The following description will be given by taking as an example that the second housing 12 and the flexible screen 20 are both movable in the width direction of the electronic device 100, but do not represent a limitation thereto.

Specifically, referring to fig. 1 in combination with fig. 3 and 4, the housing 10 includes a first housing 11 and at least one second housing 12, the first housing 11 and the second housing 12 together define a containing cavity 13, a top side of the containing cavity 13 is open, and the electronic device 100 is switchable between a folded state and an unfolded state. The flexible screen 20 is laid outside the display device and is movable between a collapsed state and an expanded state with respect to the first housing 11. The flexible screen 20 is disposed at the above-mentioned one side of the accommodating cavity 13, the driving mechanism 30 is disposed in the accommodating cavity 13, the driving mechanism 30 is directly or indirectly connected to at least one end of the flexible screen 20, and the driving mechanism 30 can drive the at least one second housing 12 and the at least one end of the flexible screen 20 to move, so as to switch the electronic device 100 between the folded state and the unfolded state. For example, when the electronic device 100 is switched from the folded state to the unfolded state, in the second direction B, at least one end of the at least one second housing 12 and the flexible screen 20 moves away from the first housing 11; when the electronic device 100 is switched from the unfolded state to the folded state, at least one end of the at least one second housing 12 and the flexible screen 20 moves toward the first housing 11.

According to the electronic device 100 of the embodiment of the present invention, the second housing 12 and the flexible screen 20 are arranged, so that the electronic device 100 can be switched between the unfolded state and the folded state, and a user can select the size of the screen of the electronic device 100 according to different usage scenarios, thereby meeting the requirements of different users and enhancing the usage experience of the user. Compared with the mode that different driving mechanisms 30 are arranged to respectively drive the flexible screen 20 and the second shell 12 to move in the prior art, the structure is simplified by the moving mode that the driving mechanisms 30 drive the second shell 12 and the flexible screen 20, and the miniaturization design of the electronic device 100 is facilitated.
