Electronic device with flexible display screen

An electronic device, comprising:

• a first housing and a second housing enclosed to form a receiving structure with an opening;
• a sliding rail mechanism provided in the receiving structure and connected to the second housing, the sliding rail mechanism being slidably provided to the first housing along a first direction;
• a flexible display screen having a first end connected with the sliding rail mechanism and a second end connected with the first housing to cover the opening;
• a driving mechanism provided in the receiving structure and connected to the first housing, the driving mechanism being connected to the sliding rail mechanism and configured to drive the sliding rail mechanism to move along the first direction;
• and
• a control mechanism comprising a displacement sensor and a controller electrically connected to the displacement sensor, the displacement sensor being configured to measure displacement change of the sliding rail mechanism relative to the first housing;
• the controller being provided at the first housing and configured to control a first stroke amount that the sliding rail mechanism moves along the first direction under drive of the driving mechanism according to the displacement change,
• wherein the driving mechanism drives the sliding rail mechanism to move along the first direction, to drive the second housing and the first end of the flexible display screen to move along the first direction relative to the first housing, such that the flexible display screen is switched between a retracted state and an expanded state,
• wherein the sliding rail mechanism comprises:
• a bracket assembly comprising a bracket;
• a sliding rail assembly comprising a fixed base, a sliding member, and an elastic assembly;
• the fixed base being fixedly connected to the bracket, the sliding member is slidably provided on the fixed base along the first direction and connected to the first end of the flexible display screen, the elastic assembly having a first end connected to the fixed base and a second end connected to the sliding member,
• wherein when the sliding member slides relative to the fixed base along the first direction, the sliding member drives the second end of the elastic assembly and the flexible display screen to move together, and the elastic assembly provides an elastic force towards the first housing on the sliding member;
• and
• wherein the fixed base is provided with a step portion extending along the first direction, and the sliding member is provided with an abutting block abutting against the step portion.
