The main body structure 42 may also be used to fix the ratchet 48, so that when the main body structure 42 moves to the first position, the ratchet 48 may be driven to approach the ratchet bar 49 and be engaged with the ratchet bar 49; when the main body structure 42 moves to the second position, the ratchet 48 can be driven away from the ratchet bar 49.

In particular, as shown in connection with fig. 6 and 7, the first position is above the second position and the ratchet bar 49 is disposed above the ratchet 48.

Specifically, the ratchet 48 and the ratchet bar 49 may constitute a ratchet mechanism to restrict the shrinkage of the second frame 3 with respect to the first frame 2. Ratchet 48 may be a gear having a rigid toothed or friction surface on either the outer or inner edges. The ratchet bar 49 may be a plurality of pawls sequentially arranged along the extending and retracting direction of the second frame 3, and the pawls may be parts for stirring the ratchet 48 to perform intermittent motion, and may drive the ratchet 48 to perform unidirectional motion.

For example: the first elastic member 43 may be an annular integral spring structure such that the structure of the first elastic member 43 may be similar or identical to the shape of the limiting structure 421. Alternatively, the first elastic member 43 may include at least two springs, and the at least two springs may be uniformly disposed along the circumferential direction of the limiting structure 421.

In the embodiment of the application, the transmission member 5 is connected with the driving mechanism 1 and the second frame body 3 respectively, so that the driving mechanism 1 drives the second frame body 3 to expand or contract relative to the first frame body 2 through the transmission member 5.

Specifically, the transmission member 5 is connected to the ratchet bar 49 and has a gap, so that the fixing frame 41 and the main body structure 42 are disposed in the gap, and since the ratchet 48 is fixed on the main body structure 42, it is convenient to realize that the ratchet 48 is opposite to the ratchet bar 49, so that the ratchet 48 is close to or far from the ratchet bar 49, and the working state of the self-locking mechanism 4 is adjusted.

Specifically, the transmission member 5 may be fixedly connected or movably connected with the second frame 3, and the transmission member 5 may push or pull the second frame 3 to move, so as to drive the flexible screen 7 to expand or contract.

Optionally, the transmission member 5 may be provided with a second accommodating groove 51 for accommodating at least part of the main body structure 42, and the self-locking mechanism 4 may further include a telescopic member 44, where the telescopic member 44 may be telescopically connected to the main body structure 42; a second limiting groove 511 may be provided on a side wall of the second accommodating groove 51 opposite to the expansion piece 44; the second limiting groove 511 is sequentially provided with a first sliding rail 5111 and a second sliding rail 5112 along a first direction, wherein the first direction may be a direction in which the ratchet 48 is far away from the ratchet bar 49; the first sliding rail 5111 and the second sliding rail 5112 may both extend in the second direction, and one end of the first sliding rail 5111 is communicated with one end of the second sliding rail 5112, and the other end of the first sliding rail 5111 is communicated with the other end of the second sliding rail 5112, and the second direction may be a direction in which the second frame 3 is unfolded relative to the first frame 2; when the self-locking mechanism 4 is switched to the locked state, the telescopic member 44 is slidably connected to the first sliding rail 5111; when the self-locking mechanism 4 is switched to the unlocking state, the telescopic member 44 is slidably connected to the second sliding rail 5112.

In this embodiment, the first sliding rail 5111 and the second sliding rail 5112 are sequentially disposed along the first direction, where the first direction is a direction in which the ratchet 48 is away from the ratchet bar 49, so that, when the main body structure 42 is switched to the first position, the self-locking mechanism 4 can be switched to a locking state, and the telescopic member 44 can slide along the first sliding rail 5111, so as to facilitate the deployment of the flexible screen 7; in the case where the main body structure 42 is switched to the second position, the self-locking mechanism 4 may be switched to the unlocked state, and the telescopic member 44 may slide on the second slide rail 5112, so that the flexible screen 7 is contracted or expanded.

Specifically, the first accommodating groove 411 may be an all-pass groove, which communicates with the second accommodating groove 51; a portion of the main body structure 42 may be embedded in the first accommodating groove 411, so that the limiting structure 421 is movably connected to the groove 4111; a portion of the main body structure 42 may be embedded in the second accommodating groove 51, so that the expansion element 44 may be slidably connected to the first sliding rail 5111 or the second sliding rail 5112.

Specifically, as shown in fig. 4, the first sliding rail 5111 is disposed above the second sliding rail 5112, so that when the main body structure 42 is switched to the first position, the telescopic member 44 can be driven to be slidingly connected to the first sliding rail 5111; when the main body structure 42 is switched to the second position, the telescopic member 44 can be driven to be slidably connected to the second sliding rail 5112.

Specifically, the first sliding rail 5111 and the second sliding rail 5112 each extend along the second direction, and one end of the first sliding rail 5111 is in communication with one end of the second sliding rail 5112, and the other end of the first sliding rail 5111 is in communication with the other end of the second sliding rail 5112, so that the telescopic member 44 is conveniently switched between the first sliding rail 5111 and the second sliding rail 5112.

Further, the height of the first sliding rail 5111 along the second direction may be sequentially reduced, so that the first sliding rail 5111 may be a slope with a height difference, so that the telescopic member 44 may slide into the second sliding rail 5112 after sliding out of the first sliding rail 5111, and the telescopic member 44 is prevented from retracting back to the first sliding rail 5111 after sliding out of the first sliding rail 5111.

Specifically, the telescoping member 44 may be telescopically coupled to the body structure 42 to adjust the length of the telescoping member 44 protruding from the body structure 42.

Alternatively, the transmission member 5 may include a limiting plate 52, the limiting plate 52 may be disposed in the second limiting groove 511, and two ends of the limiting plate 52 along the second direction are disposed at intervals from the side wall of the second limiting groove 511 in the second direction, respectively; the limiting plate 52 may sequentially include a first end and a second end along the first direction, and the thickness of the first end may be smaller than the thickness of the second end; the second end and the side wall of the second limiting groove 511 near the second end are spaced apart to form a second sliding track 5112.

Moreover, the two ends of the limiting plate 52 along the second direction are respectively arranged at intervals with the side walls of the second limiting groove 511 along the second direction, so that the first sliding rail 5111 and the second sliding rail 5112 can be effectively ensured to be communicated.

Specifically, the first end of the limiting plate 52 may be located above the second end, and the thickness of the first end is smaller than that of the second end, so that the first end of the limiting plate 52 may form the first sliding track 5111, and the telescoping member 44 may be prevented from sliding into the second sliding track 5112 on the limiting plate 52, thereby improving the sliding reliability of the telescoping member 44 along the first sliding track 5111.
