It should be noted that, in the embodiment of the present application, the coverage length of the flexible screen 2 on the lower surface of the terminal device does not exceed the length of the second frame 20 along the direction of expanding or collapsing the flexible screen 2. In practical application, the covering length of the flexible screen 2 on the lower surface of the terminal device can be designed according to practical application requirements, which is not limited by the application.
In practical application, the fixing connection manner between one end of the flexible screen 2 and the first frame 10 and the fixing connection manner between the other end of the flexible screen 2 and the tensioning mechanism 30 include, but are not limited to, gluing, bonding or pasting manners.

When the first frame 10 is kept relatively stationary and the movement distance of the second frame 20 relative to the first frame 10 is L during the deployment of the flexible screen 2, the movement distance of the tensioning mechanism 30 fixedly connected to the flexible screen 2 relative to the first frame 10 is 2L. That is, the length of the screen size of the flexible screen 2 laid on the upper surfaces of the first and second frames 10 and 20 in the direction in which they are spread out will increase by L.
The screen adjusting mechanism 1 of the terminal equipment provided by the embodiment of the application is provided with the tensioning mechanism 30, because one end of the tensioning mechanism 30 is fixedly connected with the other end of the flexible screen 2, the other end of the tensioning mechanism 30 is fixedly connected with the first frame 10, when the second frame 20 and the first frame 10 are unfolded, the tensioning mechanism 30 is driven to move away from the first frame 10 along with the other end of the flexible screen 2 which is unfolded by the second frame 20 and the first frame 10, the flexible screen 2 is unfolded by the flexible screen 2 driving the tensioning mechanism 30 to move, so that the flexible screen 2 is in a tensioning state in the unfolding process, and when the second frame 20 and the first frame 10 are contracted, the flexible screen 2 is pulled to move towards the direction close to the first frame 10 by the tensioning mechanism 30, so that the flexible screen 2 is folded by the flexible screen 2 which is pulled to move towards the direction close to the first frame 10, and the flexible screen 2 is also in the tensioning state in the folding process. Therefore, the tensioning mechanism 30 can enable the flexible screen 2 to be kept flat in the unfolding or folding process, and effectively solves the problems of wrinkling, bubbling and arching of the flexible screen 2 in the unfolding or folding process.
In one possible embodiment, as shown in a schematic structural diagram of a tensioning mechanism 30 shown in fig. 10, referring to fig. 10, the tensioning mechanism 30 includes at least one rope 301, a first boss 101 corresponding to each rope 301 is disposed on the first frame 10 near a first edge area of the second frame 20 at intervals, a first sliding groove 201 corresponding to each first boss 101 is disposed on the second frame 20, the first bosses 101 are slidably connected with the corresponding first sliding grooves 201, so that the first bosses 101 can slide in the first sliding grooves 201 along the telescopic directions of the first frame 10 and the second frame 20, a second boss 202 is disposed on one end of each first sliding groove 201 near the first frame 10, one end of the rope 301 is fixedly connected with the corresponding first boss 101, and the other end of the rope 301 bypasses the corresponding second boss 202 and is fixedly connected with the other end of the flexible screen 2.

The two ends of the first supporting rod 302 are slidably connected to the second frame 20, so that the movement range of the first supporting rod 302 on the second frame 20 can be limited, and the limiting and guiding functions are achieved.
Based on the above embodiment, after the other end of the flexible screen 2 bypasses the one end of the second frame 20 away from the first frame 10 and is fixedly connected with the first support rod 302, the problem that the other end of the flexible screen 2 is directly connected with the tensioning mechanism 30 to cause wrinkles and arching in the edge area of the flexible screen 2 is avoided, the stress area of the edge area of the flexible screen 2 is increased, the stress is more uniform, the flatness of the flexible screen 2 in the unfolding or folding process is effectively ensured, and the service life of the flexible screen 2 is prolonged.

Optionally, the first elastic member 303 includes, but is not limited to, a spring or a rubber band (e.g., a rubber band, an elastic band) or the like that can provide a desired elastic force to keep the flexible screen 2 flat during the unfolding or folding process.
