Electronic device

An electronic device, comprising a first screen support, a second screen support, a flexible screen, and an auxiliary extending/retracting mechanism, wherein the first screen support and the second screen support are configured to be movable relative to each other and cooperate with each other to cause the electronic device to switch between a folded state and an unfolded state, the flexible screen is arranged on the first screen support and the second screen support, a first end of the flexible screen is connected to the second screen support, and a second end of the flexible screen is bent to a side of the first screen support facing away from the first end and is arranged in the electronic device;

• the auxiliary extending/retracting mechanism comprises a first transmission member, a second transmission member, a third transmission member, and an elastic member, the first transmission member is fixedly connected to the second screen support and is located on a side of the second screen support facing away from the flexible screen, the second transmission member is rotatably connected to the first screen support, the third transmission member is slidably connected to the first screen support or the second screen support, the second transmission member is located between the first transmission member and the third transmission member, the first transmission member cooperates with the second transmission member, the second transmission member cooperates with the third transmission member, one end of the elastic member is connected to the third transmission member, and the other end of the elastic member is connected to the second end of the flexible screen;
• and when the electronic device switches between the folded state and the unfolded state, the first screen support drives the second transmission member to move, the first transmission member drives the second transmission member to rotate, the second transmission member drives the third transmission member to move in a movement direction of the first screen support, and the third transmission member drives, via the elastic member, the second end of the flexible screen to move;
• and wherein the first transmission member is a firs track, the second transmission member is a gear set, the third transmission member is a second rack, and the gear set is meshed with the first rack and the second rack;
• and the auxiliary extending/retracting mechanism further comprises a mounting housing, a sliding block, and a guide shaft, the mounting housing is fixedly connected to the third transmission member, the mounting housing is provided with an accommodating space, the sliding block and the elastic member are located in the accommodating space, one end of the elastic member is connected to the sliding block, the other end of the elastic member is connected to the mounting housing, a part of the guide shaft is arranged in the accommodating space, the elastic member is sleeved on the guide shaft, one end of the guide shaft is connected to the sliding block, and the other end of the guide shaft is connected to the second end of the flexible screen.
