Specifically, the body 11 has a first groove 111, and a circle of inner side walls of the first groove 111 may be circular, polygonal, or other shapes. The body 11 may be provided with a connection structure, which can connect the body 11 to other devices, such as: the body 11 is provided with a coupling hole so that a screw can pass through the coupling hole and be coupled with a first rotating assembly 21 hereinafter.

In particular, the outer side wall of the first movable member 12 may abut against the inner side wall of the first recess 111, so that the first movable member 12 moves more smoothly relative to the first body 11.

The driving member 13 is connected with the first movable member 12 through the first cavity 112 on the body 11, the first cavity 112 extends from the bottom wall of the first groove 111 towards the notch of the first groove 111, that is, the bottom wall of the first groove 111 of the body 11 extends towards the notch direction of the first groove 111 to form an extension portion 113, an annular groove is formed between the extension portion 113 and the inner side wall of the first groove 111, the first movable member 12 is disposed in the annular groove and sleeved on the extension portion 113, and the first movable member 12 can reciprocate relative to the annular groove, meanwhile, the inside of the extension portion 113 is hollow to form the first cavity 112, and the driving member 13 is arranged in the first cavity 112 of the extension portion 113 in a penetrating manner and connected with the first movable member 12. When the driving member 13 moves along the first cavity 112 toward the notch of the first recess 111, the first movable member 12 can move toward the bottom wall of the first recess 111, in other words, the movement direction of the driving member 13 is opposite to the movement direction of the first movable member 12.

In one embodiment, referring to fig. 1 to 8, an electronic device 30 includes: the device comprises a bracket 31, a display screen 32 and a telescopic structure 10, wherein the bracket 31 is provided with a first rotary component 21 capable of lifting and a driving part 311 corresponding to the highest lifting position; the display screen 32 is provided with a second rotating member 22, a second surface of the second rotating member 22 is rotatably connected with a first surface of the first rotating member 21, and a locking hole 221 is provided on the second surface. Wherein the telescopic structure 10 comprises: the body 11, the first movable part 12 and the driving part 13, the body 11 is connected with the first rotating assembly 21, the notch of the first groove 111 of the body 11 faces the second surface, the bottom of the first groove 111 extends to the notch of the first groove 111 to form an extension part 113, an annular groove is formed between the extension part 113 and the inner side wall of the first groove 111, and the inside of the extension part 113 is hollow to form a first cavity 112; the first movable member 12 is sleeved on the extension portion 113 and can reciprocate relative to the body 11 in the first groove 111; the driving member 13 is disposed through the first cavity 112 on the body 11 and connected to the first movable member 12.

When the first rotating assembly 21 is at a non-highest position relative to the bracket 31, that is, the first rotating assembly 21 is correspondingly at the lower end of the bracket 31 or in the process of ascending relative to the bracket 31, the first movable member 12 is positioned in the locking hole 221, so that the first rotating assembly 21 and the second rotating assembly 22 cannot rotate relatively, and the display screen 32 cannot rotate to collide with the bracket seat 312.

Further, when the first rotating assembly 21 is lifted to the highest position relative to the bracket 31, the driving inclined surface of the driving part 311 abuts against the driving member 13, so that the driving member 13 moves along the first cavity 112 towards the notch of the first groove 111, and the first movable member 12 moves towards the bottom wall of the first groove 111 to be separated from the locking hole 221. Since the first movable member 12 is disengaged from the locking hole 221 to achieve relative unlocking between the first rotating assembly 21 and the second rotating assembly 22, the first rotating assembly 21 and the second rotating assembly 22 can relatively rotate from a zero angle to a first angle, and since the first rotating assembly 21 is located at the upper end of the bracket 31, the display screen 32 is supported at the upper end of the bracket 31 through connection of the second rotating assembly 22 and the first rotating assembly 21, and in this position, the display screen 32 is higher so that the display screen 32 does not collide with the bracket seat 312 when rotating.

Then, when the display screen 32 needs to be lowered, the first rotating assembly 21 and the second rotating assembly 22 are relatively rotated, so that the display screen 32 is rotated to return to zero angle; then, during the process of lowering the display screen 32, the driving part 311 is separated from the driving part 13, so that the driving part 13 moves along the first cavity 112 towards the bottom wall of the first groove 111, so that the first movable part 12 moves towards the notch of the first groove 111 to be inserted into the locking hole 221, and at this time, the first rotating assembly 21 and the second rotating assembly 22 are in a locked state that can not rotate relatively.

In the implementation process, the method is not limited by the highest position, for example: when the display screen 32 is rotated at a certain height without colliding with the stand base 312, the driving part 311 may be provided at the height.

In this embodiment, the bracket 31 is provided with a first rotating assembly 21, and the display screen 32 is provided with a second rotating assembly 22 rotatably connected to the first rotating assembly 21, so that after the first rotating assembly 21 and the second rotating assembly 22 rotate relatively, the display screen 32 rotates relatively to the bracket 31. Meanwhile, the first rotating assembly 21 is provided with the telescopic structure 10, the second rotating assembly 22 is provided with the locking hole 221, the first movable piece 12 of the telescopic structure 10 stretches into the locking hole 221 so that the first rotating assembly 21 and the second rotating assembly 22 are relatively locked to be unable to rotate, and after the first rotating assembly 21 rises to a certain height relative to the bracket 31, the first movable piece 12 is separated from the locking hole 221 so that the first rotating assembly 21 and the second rotating assembly 22 can relatively rotate; it can be seen that, the display screen 32 can rotate relative to the bracket 31, so that the first rotating assembly 21 lifts the display screen 32 relative to the bracket 31, and the lifted display screen 32 is separated from the bracket seat 312 by a large distance, so that the collision probability with the bracket seat 312 during the rotation of the display screen 32 can be avoided.

In some embodiments, referring to fig. 1 to 3, the first movable member 12 is provided with a second groove 121, and the notch of the second groove 121 faces the bottom wall of the first groove 111; the telescopic structure 10 further comprises an elastic member 14 disposed between the first end of the driving member 13 and the first movable member 12, the first end being an end of the driving member 13 facing the bottom wall of the second recess 121, the elastic member 14 being capable of providing a pushing force to the driving member 13 moving toward the bottom wall of the first recess 111, so that the driving member 13 drives the first movable member 12 to move toward the notch of the first recess 111.

Specifically, the first movable member 12 is provided with the second groove 121, and the notch of the second groove 121 faces the bottom wall of the first groove 111, so that the body 11 and the first movable member 12 are fastened to each other, and the inner bottom wall of the first groove 111 and the inner bottom wall of the second groove 121 face each other.

In one embodiment, when the display screen 32 is at the non-highest position, the elastic member 14 is in a normal extended state, and the first movable member 12 extends into the locking hole 221, and no relative rotational movement can occur between the first rotating member 21 and the second rotating member 22. Then, when the display screen 32 is lifted to the highest position, the driving part 311 pushes the driving part 13, so that the driving part 13 pushes the first movable part 12 to move along the first cavity 112 toward the bottom wall of the first groove 111 to compress the elastic part 14, thereby disengaging the first movable part 12 from the locking hole 221, and at this time, the first rotating assembly 21 and the second rotating assembly 22 can rotate relatively. Further, when the display screen 32 descends, the driving portion 311 is separated from the driving member 13, and the elastic member 14 is elastically restored to provide a pushing force to the driving member 13 for moving toward the bottom wall of the first recess 111, so that the driving member 13 drives the first movable member 12 to move toward the notch of the first recess 111 and extend into the locking hole 221, and at this time, no relative rotation movement can occur between the first rotating assembly 21 and the second rotating assembly 22.

In this embodiment, the second movable member 15 is obliquely inserted through the driving member 13, and when the driving member 13 moves toward the notch or the bottom wall of the first recess 111, the second movable member 15 interacts with the guiding portion 122 on the first movable member 12 to drive the first movable member 12 to move relative to the first recess 111.
