In one embodiment, a rotating shaft 21 is arranged in the second body 2, the fixed side of the flexible screen 3 is fixedly connected to the first body 1, and the movable side of the flexible screen 3 bypasses the rotating shaft 21 and is connected to the tensioning member 5 through an elastic member 6 in a stretching state; for example, the flexible screen 3 may include the fixed side and the movable side opposite to each other, and the rotating shaft 21 may rotate while moving, so as to drive the flexible screen 3 to expand and retract.
Under the condition that the second main body 2 and the first main body 1 slide relatively, the driving piece drives the tensioning piece 5 and the second main body 2 to move in the same direction, that is, the tension of the elastic piece 6 can be made to approach in the process of unfolding the electronic device, so that the additional resistance brought by the tension change of the elastic piece 6 to the unfolding or the retraction of the flexible screen 3 is avoided, and the stability and the service life of the unfolding or the retraction of the flexible screen 3 are ensured.
In addition, when the tension of the elastic part 6 is close to the tension in the folding and unfolding process of the electronic equipment, the power of a motor for driving the flexible screen 3 to unfold or retract can be kept constant, the service life of the motor is prolonged, and the electric quantity loss of the motor is reduced.
In particular, the rate of movement of the tensioning member 5 is greater than the rate of relative sliding of the second body 2 and the first body 1.
Specifically, when the driving member drives the tensioning member 5 to move in the same direction as the second body 2, the moving speed of the movable side of the flexible screen 3 is greater than the speed of relative sliding between the second body 2 and the first body 1. In the process of unfolding the electronic device, in order to avoid excessive deformation of the elastic member 6 between the movable side and the tensioning member 5, the movement rate of the tensioning member 5 may be greater than the relative sliding rate of the second body 2 and the first body 1, so as to match the movement rate of the tensioning member 5 with the movement rate of the movable side of the flexible screen 3, and ensure the stability of unfolding or retracting the flexible screen 3.
In a particular embodiment, the movement rate of the tensioning member 5 is 1.8-2.2 times the relative sliding rate of the second body 2 and the first body 1, i.e. the movement rate of the tensioning member 5 is close to twice the relative sliding rate of the second body 2 and the first body 1, so that the movement of the tensioning member 5 can match the rate of the flexible screen 3 being deployed or retracted, ensuring that the rate of change of the tensile elongation of the elastic member 6 is less than or equal to 10%, i.e. making the tension of the elastic member 6 nearly constant, avoiding the change of the tension of the elastic member 6 to bring extra resistance to the flexible screen 3 being deployed or retracted, ensuring the stability and the service life of the flexible screen 3 being deployed or retracted.
Optionally, the rate of movement of the tensioning member 5 is 2 times the rate of relative sliding of the second body 2 and the first body 1, so that the rate of change of the tensile elongation of the elastic member 6 is less than or equal to 2%.

Specifically, when the second slide bar assembly 22 drives the first gear 4 to move, a protrusion may be provided on the second slide bar assembly 22, and the protrusion abuts against one side of the first gear 4 close to the first main body 1. Since the first gear wheel 4 is in threaded engagement with the first slide bar assembly 11, the projection, when pushing the first gear wheel 4 away from the first body 1, allows the first gear wheel 4 to move along the first slide bar assembly 11 while rotating on the first slide bar assembly 11, i.e. allows a synchronous movement of the first gear wheel 4 and the second slide bar assembly 22.
Moreover, when the first gear 4 rotates on the first sliding rod assembly 11, the tensioning member 5 can be in threaded fit with the first gear 4, for example, in a form of a rotational thread, so that the first gear 4 drives the tensioning member 5 to move in the same direction as the first gear 4 during the rotation, and the speed of the tensioning member 5 moving relative to the first gear 4 can be flexibly adjusted by controlling the thread size and the thread pitch of the thread, for example, the moving speed of the tensioning member 5 is adjusted to 2 times of the moving speed of the first gear 4, so as to ensure that the stretching length of the elastic member 6 is kept unchanged.
Alternatively, referring to fig. 1 and 2, the first body 1 is a fixed body, the second body 2 is a moving body, and the first sliding bar assembly 11 is fixedly disposed in the first body 1.
Specifically, when the first body 1 and the second body 2 slide relative to each other, in a case where the first body 1 is a fixed body and the second body 2 is a moving body, a user may hold the first body 1 and then slide the first body 1 and the second body 2 relative to each other by pulling the second body 2. When the first slide bar assembly 11 is fixedly disposed in the first main body 1, for example, the first slide bar assembly 11 is fixedly disposed in the first main body 1 by bolt fastening or adhesive fastening, so as to ensure that the first slide bar assembly 11 and the first main body 1 are relatively stable, and the first gear 4 can stably rotate and move on the first slide bar assembly 11.
Optionally, the driving member is a motor assembly or a cylinder assembly.
Specifically, the driving member is provided for driving the tensioning member 5 to move in the same direction as the second body 2, and the movement rate of the tensioning member 5 is 1.8-2.2 times the relative sliding rate of the second body 2 and the first body 1, so as to ensure that the tensile elongation change rate of the elastic member 6 is less than or equal to 10%. And the movement of the tensioning member 5 can be achieved by means of a motor assembly or a cylinder assembly. For example, a motor assembly is arranged in the second main body 2 or the first main body 1, an output shaft of the motor assembly is connected with the tensioning member 5, and the output shaft of the motor assembly can drive the tensioning member 5 to move when extending out or retracting, so that the purpose that the tensioning member 5 and the second main body 2 move in the same direction is achieved.

Specifically, when the second body 2 and the first body 1 slide relatively, the first support member 12 and the second support member 23 may be far away from or close to each other, and in order to avoid that a gap formed when the first support member 12 and the second support member 23 are far away from each other cannot support the flexible screen 3, the first support member 12 and the second support member 23 may be set to be a comb structure and may be inserted into and matched with each other, and even if the first support member 12 and the second support member 23 are far away from each other, the matching relationship of the insertion may be maintained, so as to ensure stable support of the flexible screen 3.
Alternatively, referring to fig. 1 and 2, the second sliding rod assembly 22 comprises a sliding rod 221 and a scraper 222 which are connected with each other, the sliding rod 221 is rotatably connected to the second support 23, and the scraper 222 abuts on the first gear 4;
the sliding rod 221 drives the first gear 4 to rotate through the scraper 222 in the process of moving away from the first main body 1, and moves away from the first main body 1 synchronously with the scraper 222.
Specifically, the sliding rod 221 may be rotatably connected to the second supporting member 23, wherein a fixed seat 7 is fixed on the second supporting member 23, and the sliding rod 221 is rotatably connected to the second supporting member 23 through a bearing on the fixed seat 7. The contact between the scraper 222 and the first gear 4 may be such that at least a part of the scraper 222 contacts the first gear 4 on the side closer to the first body 1.
When the first main body 1 slides relatively in a direction away from the second main body 2, the first main body 1 can drive the sliding rod 221 to move away from the second main body 2 through the second supporting member 23, so that the scraper 222 can drive the first gear 4 to move away from the first main body 1 together. Moreover, due to the threaded fit between the first gear 4 and the first slide bar assembly 11, the first gear 4 and the scraper 222 can simultaneously rotate on the first slide bar assembly 11, so that the first gear 4 drives the second slide bar assembly 22 to rotate.
