Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The embodiments in the present application may be combined as appropriate.

For foldable devices such as foldable mobile phones, in order to realize bending of the flexible display screen, two ends of the flexible display screen are respectively fixed on the left shell component and the right shell component. When the foldable equipment is switched between the unfolding state and the folding state, the part of the flexible display screen corresponding to the rotating shaft assembly can be bent. In order to ensure free bending of the flexible display screen, the flexible display screen corresponding to the rotating shaft assembly is not adhered to the rotating shaft assembly or the shell assembly. However, this brings with it new problems: when the flexible display screen is mutually switched between the unfolding state and the folding state, because no reliable mechanism supports the flexible display screen to be completely unfolded, the flexible display screen has folds or even reverse bending due to the redundant length of the part corresponding to the rotating shaft assembly. In addition, if the foldable device accidentally falls down in the unfolded state, the shell assembly on the left side, the shell assembly on the right side and the rotating shaft assembly are not firmly connected and are easy to dislocate, so that the flexible display screen is dislocated and fails.

The second surface 32 of the second housing component 3 is also provided with a second sliding projection 34. Further, the second slide protrusion 34 is provided on the bottom surface of the second lower groove 221. The rotating shaft component 1 is provided with a sliding chute 14. The chute 14 may extend in the X-axis direction. Further, the slide groove 14 is provided on an arc-shaped bottom surface (a surface facing the first housing member 2 and the second housing member 3) of the rotary shaft member 1. During the unfolding of the first housing component 2 and the second housing component 3, the first sliding projection 24 and the second sliding projection 34 enter the sliding groove 14 from the two end openings of the sliding groove 14, and slide along the sliding groove 14.

Due to the smaller size of the first recess 61 and the first bump 51. If in the process of unfolding the first shell assembly 2 and the second shell assembly 3, the first shell assembly 2 and the second shell assembly 3 are dislocated in the extending direction of the rotating shaft assembly 1, so that the first groove 61 and the first bump 51 cannot be accurately aligned, and further the first shell assembly 2 and the second shell assembly 3 cannot be quickly unfolded. Therefore, by providing the sliding groove 14, the first sliding protrusion 24 and the second sliding protrusion 34 as a moving guide for providing the first protrusion 51, the first protrusion 51 on the first housing component 2 and the first groove 61 of the second housing component 3 move along the same track, so as to ensure the alignment and quick engagement of the first groove 61 and the first protrusion 51.

The following embodiments exemplify the structures of the first groove 61 and the first bump 51, and of course, the structures of the first groove 61 and the first bump 51 in the present application include, but are not limited to, the following embodiments.

In one embodiment, referring to fig. 11, the first groove 61 is disposed on the first side surface 33 and penetrates the first surface 31 and the second surface 32. Referring to fig. 5, the first bump 51 is protruded on the second side 23. As such, first protrusion 51 is capable of moving into first groove 61 through the opening of first groove 61 on first surface 31 to facilitate flattening of first housing component 2 and second housing component 3.

Specifically, the shape of the first groove 61 includes, but is not limited to, a semicircle, a rectangle, a trapezoid, a triangle, etc. It will be appreciated that the shape of the first projection 51 is adapted to the shape of the first recess 61.

In another embodiment, referring to fig. 12, the first groove 61 may be disposed on the first side surface 33 without penetrating through the first surface 31 and the second surface 32. Specifically, the first recess 61 may be a hemispherical groove, and the first bump 51 is a hemispherical bump. When the first side 33 abuts against the second side 23, the first protrusion 51 can move into the first groove 61, so that the first housing component 2 and the second housing component 3 are connected and form a firm whole.

It is understood that the shapes of the second recess 52 and the second protrusion 62 can refer to the first recess 61 and the first protrusion 51, and are not described herein.

The following embodiments illustrate the structure of the first bump 51 when the first groove 61 penetrates the first surface 31 and the second surface 32, and the first bump 51 in the present application includes, but is not limited to, the following embodiments.

Referring to fig. 13, the first bump 51 includes a first end 511 fixed to the first housing element 2 and a second end 512 far away from the first housing element 2. The dimension of the first end 511 in the extending direction of the spindle assembly 1 is larger than the dimension of the second end 512 in the extending direction of the spindle assembly 1. In other words, the size of the end of the first bump 51 away from the second side 23 is smaller than the size of the end of the first bump 51 fixed to the second side 23. Further, the size of the first bump 51 may be gradually reduced in a direction away from the second side surface 23.

During the unfolding process of the first housing component 2 and the second housing component 3, the second end 512 of the first protrusion 51 is first disposed in the first groove 61. At this time, the second end 512 of the first protrusion 51 is designed to be smaller than the first end 511 of the first protrusion 51, so that when there is a small deviation between the first protrusion 51 and the first groove 61 in the extending direction of the rotating shaft assembly 1, the first protrusion 51 can still be smoothly located in the first groove 61, and the first protrusion 51 is further promoted to be engaged with the first groove 61 of the second housing assembly 3.

In one embodiment, referring to fig. 13, the first groove 61 is an arc-shaped groove, and an end surface of the first bump 51 along the Y-axis direction is an arc-shaped surface.

In another embodiment, referring to fig. 14, the first groove 61 is a trapezoid groove, and the orthographic projection of the first bump 51 on the X-Y plane is a trapezoid.

Further, the side wall of the first protrusion 51 is also curved in the Z-axis direction, so that the first protrusion 51 can move into or out of the first groove 61 smoothly.

In one possible embodiment, referring to fig. 15, a limiting plate 611 is disposed in the first groove 61. The limiting plate 611 is located at an opening at one end of the first groove 61. During the unfolding of the first housing component 2 and the second housing component 3, the first protrusion 51 opens into the first groove 61 from the other end of the first groove 61. When the first housing assembly 2 and the second housing assembly 3 are flattened, the first protrusion 51 abuts against the limit plate 611.

Specifically, the limiting plate 611 may be parallel to the second surface 32 or coplanar with the second surface 32. The stopper plate 611 may be integrally formed with the second housing assembly 3. The stopper plate 611 is used to block the opening of the first groove 61 on the second surface 32 side. The limiting plate 611 is used to limit the first housing assembly 2 and the second housing assembly 3 when they are unfolded to 180 °, so that the intersection angle of the flattened state of the first housing assembly 2 and the second housing assembly 3 is 180 °.

Correspondingly, a plate for limiting is also arranged in the second groove 52. When the first protrusion 51 abuts against the limiting plate 611 in the first groove 61 and the second protrusion 62 abuts against the plate for limiting in the second groove 52, the first casing assembly 2 and the second casing assembly 3 are in the flat state and reach the unfolding end point.

Further, referring to fig. 16, the foldable device 100 further includes a first connecting shaft 20, a first elastic pad 30, a second connecting shaft 40 and a second elastic pad 50. The first connecting shaft 20 is connected between the rotating shaft assembly 1 and the first housing assembly 2.

The first elastic pad 30 is sleeved on the first connecting shaft 20, and the first elastic pad 30 can be clamped between the first housing assembly 2 and the rotating shaft assembly 1. The second elastic pad 50 is sleeved on the second connecting shaft 40, and the second elastic pad 50 can be clamped between the second housing assembly 3 and the rotating shaft assembly 1.

Due to manufacturing tolerances or assembly tolerances, when the flattened states of the first case assembly 2 and the second case assembly 3 have a difference in pitch in the thickness direction, the flattened states of the first case assembly 2 and the second case assembly 3 may not be coplanar. First resilient pads 30 can compensate first casing subassembly 2 and the ascending interval difference of second casing subassembly 3 in thickness direction, and then make first lug 51 can butt limiting plate 611 in first recess 61, and second lug 62 can be used for spacing plate in the butt second recess 52 smoothly, and can not die, and then coplane when making first casing subassembly 2 and the flattening of second casing subassembly 3, improve foldable device 100's whole expressive force.

In the above embodiment, the first bump 51 and the first groove 61 are exemplified, the shape of the second bump 62 may be the same as the shape of the first bump 51, and the shape of the first groove 61 may be the same as the shape of the second groove 52, so the shapes of the second bump 62 and the second groove 52 are not described herein again.

In one embodiment, referring to fig. 17, when the first housing component 2 and the second housing component 3 are unfolded, the first side surface 33 abuts against the second side surface 23.
