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, no reliable mechanism supports the flexible display screen to be completely unfolded, so that the flexible display screen is folded due to the fact that the length of the part corresponding to the rotating shaft assembly is redundant, and even reversely bent. In addition, if the foldable device falls accidentally, 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. In addition, the folding terminal falls accidentally, and when the rotating shaft assembly lands on the ground first, due to the action of instant impact force, the rotating shaft assembly can generate dislocation with the shell assembly on the left side and the shell assembly on the right side, so that the flexible display screen also generates dislocation synchronously, and the flexible display screen can be caused to lose efficacy.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a foldable device according to an embodiment of the present disclosure. The foldable device 100 may be a foldable display device, such as a mobile phone, a tablet, an e-reader, a computer, an electronic display screen, and other display devices. It will be appreciated that the foldable device 100 may also be a foldable non-display device. The present application exemplifies a foldable mobile phone. In this embodiment, the length direction of the foldable device 100 is defined as the Y-axis direction. The width direction of the foldable device 100 is defined as the X-axis direction. The thickness direction of the foldable device 100 is defined as the Z-axis direction. The bending axis of the foldable device 100 is along the Y-axis direction.

The flexible display screen 4 is arranged on the first shell component 2, the rotating shaft component 1 and the second shell component 3. Specifically, the flexible display screen 4 is fixedly connected to the first housing assembly 2 and the second housing assembly 3. The flexible display screen 4 is not fixedly connected with the rotating shaft assembly 1, so that the bending part of the flexible display screen 4 can be freely bent.

Referring to fig. 4 to 6, the rotating shaft assembly 1 includes a first engaging member 11 and a second engaging member 12. The first housing component 2 includes a first engaging portion 21.

When the first housing assembly 2 and the second housing assembly 3 are unfolded, the first engaging portion 21 is engaged with the first engaging member 11, and the second engaging portion 31 is engaged with the second engaging member 12. It is understood that the first case assembly 2 and the second case assembly 3 are flattened means that the first case assembly 2 and the second case assembly 3 are unfolded to 180 °.

In other words, referring to fig. 4, when the first housing component 2 and the second housing component 3 are spread flat, one end of the first housing component 2 abuts against one end of the second housing component 3, the first housing component 2 and the rotation shaft component 1 are fixedly connected through the first clamping piece 11 and the first clamping portion 21, and the second housing component 3 and the rotation shaft component 1 are fixedly connected through the second clamping piece 12 and the second clamping portion 31, so that the first housing component 2, the rotation shaft component 1 and the second housing component 3 are connected into a whole, and a flattened support is provided for the flexible display screen 4, so that the flexible display screen 4 is completely spread.

It can be understood that, when the first housing assembly 2 and the second housing assembly 3 are folded, the first housing assembly 2 and the second housing assembly 3 can rotate around the rotating shaft assembly 1 by overcoming the fastening connection force between the first fastening member 11 and the first fastening portion 21 and overcoming the fastening connection force between the second fastening member 12 and the second fastening portion 31 until the first housing assembly 2 and the second housing assembly 3 are folded. It is understood that the folded state of the first housing assembly 2 and the second housing assembly 3 refers to a state in which an end of the first housing assembly 2 away from the rotary shaft assembly 1 and an end of the second housing assembly 3 away from the rotary shaft assembly 1 abut against each other.

The first clamping piece 11 and the second clamping piece 12 are arranged on the rotating shaft component 1, and the first shell component 2 and the second shell component 3 are respectively provided with the first clamping part 21 and the second clamping part 31, so that when the first shell component 2 and the second shell component 3 are unfolded, the first clamping piece 11 is clamped and connected with the first clamping part 21, and the second clamping piece 12 is clamped and connected with the second clamping part 31, so that the first shell component 2, the second shell component 3 and the rotating shaft component 1 are connected into a whole, a leveling support is provided for the flexible display screen 4, the flexible display screen 4 is completely unfolded, wrinkles or reverse bending cannot occur, and the expressive force of the foldable equipment 100 is improved; moreover, the first shell assembly 2, the second shell assembly 3 and the rotating shaft assembly 1 are connected into a whole, so that the foldable device 100 can be effectively prevented from being loosened or colliding with each other to cause dislocation when falling accidentally in the unfolded state, the flexible display screen 4 is prevented from causing dislocation and losing efficacy, the reliability of the flexible display screen 4 is improved, and the stability of the foldable device 100 is improved.

In other words, the first shell assembly 2, the second shell assembly 3 and the rotating shaft assembly 1 can provide the foldable device 100 which is buckled with each other, so that the first shell assembly 2 and the second shell assembly 3 can keep a flat state, the flexible display screen 4 can keep being completely unfolded in an unfolding state, redundancy of the flexible display screen 4 in the rotating shaft assembly 1 region is avoided, meanwhile, dislocation of the first shell assembly 2 and the second shell assembly 3 when the foldable device 100 is in the unfolding state and falls to the ground is avoided, impact on the flexible display screen 4 is reduced, and the problems that the flexible display screen 4 is prone to failure when the flexible display screen 4 is folded, reversely arched and the foldable device 100 is unfolded, falls to the ground can be effectively solved.

Further, referring to fig. 6, the rotating shaft assembly 1 includes a base 13, and a first rotating mechanism 14 and a second rotating mechanism 15 connected to the base 13. One end of the first rotating mechanism 14 is rotatably connected to the base 13. The rotation axis of the first rotation mechanism 14 is along the Y-axis direction, which is also the extending direction of the base 13. The other end of the first rotation mechanism 14 is connected to the first housing assembly 2. The second rotating mechanism 15 and the first rotating mechanism 14 are symmetrically arranged on two opposite sides of the base 13. One end of the second rotating mechanism 15 is rotatably connected to the base 13. The other end of the second rotating mechanism 15 is connected to the second housing member 3. The first rotating mechanism 14 and the second rotating mechanism 15 realize that the first shell assembly 2 and the second shell assembly 3 are rotatably connected with the rotating shaft assembly 1, and further realize the flattening or folding of the first shell assembly 2 and the second shell assembly 3.

Referring to fig. 4, when the first housing assembly 2 and the second housing assembly 3 are unfolded and flat, the first housing assembly 2 and the second housing assembly 3 are coplanar and abutted against each other, and the base 13, the first rotating mechanism 14 and the second rotating mechanism 15 are disposed between the housing formed by the first housing assembly 2 and the second housing assembly 3 and the flexible display screen 4.

Referring to fig. 5, the base 13 has a first surface 131. The first surface 131 is an outer surface of the base 13. The first surface 131 faces the first case assembly 2 and the second case assembly 3 when the first case assembly 2 and the second case assembly 3 are flattened. In other words, the first surface 131 is the surface of the hinge assembly 1 facing away from the flexible display 4. The first housing member 2 has a first housing face 22, and the first housing face 22 is opposed to the first surface 131 when the first housing member 2 and the second housing member 3 are flattened. The second housing member 3 has a second housing face 32, and the second housing face 32 is opposed to the first surface 131 when the first housing member 2 and the second housing member 3 are flattened.

The first and second engaging members 11 and 12 are disposed on the first surface 131. The first engaging portion 21 and the second engaging portion 31 are respectively disposed on the first housing surface 22 and the second housing surface 32, so that the first engaging member 11 and the first engaging portion 21 can be engaged and connected, and the second engaging member 12 and the second engaging portion 31 can be engaged and connected.

Further, referring to fig. 5, the first surface 131 may be an arc surface. The first housing face 22 and the second housing face 32 are arc-shaped faces adapted to the first surface 131. The design is such that during the rotation of the first housing component 2 and the second housing component 3 around the rotating shaft component 1, the first housing face 22 and the second housing face 32 are both close to the first surface 131, which improves the compactness of the foldable device 100.

The following embodiments exemplify specific configurations of the first clip 11 and the first engaging portion 21. Of course, specific configurations of the first clip 11 and the first engaging portion 21 in the present application include, but are not limited to, the following embodiments.

Referring to fig. 5 and 7, the first clip member 11 includes a first elastic protrusion 111. The first engaging portion 21 includes a first groove 212. In the process of unfolding the first housing component 2 and the second housing component 3, the first engaging portion 21 presses the first elastic protrusion 111 until the first elastic protrusion 111 is disposed in the first groove 212.

Specifically, referring to fig. 5 and fig. 7, the first engaging portion 21 includes a first protrusion 211 disposed on the first housing surface 22 and a first groove 212 disposed on the first protrusion 211. The first recess 212 is provided on a surface of the first elevation 211 facing away from the first housing face 22. In the process of unfolding the first housing component 2 and the second housing component 3, the first housing face 22 is gradually close to the first surface 131, the first boss 211 is driven to be gradually close to the first elastic protrusion 111 until the first boss 211 abuts against the first elastic protrusion 111, the first boss 211 extrudes the first elastic protrusion 111 along with the continuous approach of the first housing face 22 to the first surface 131, and the first boss 211 is arranged in the first groove 212 until the first elastic protrusion 111 is arranged in the first groove 212, so that the first clamping piece 11 is clamped to the first clamping portion 21.

Correspondingly, referring to fig. 5 and fig. 7, the second clip 12 includes a second elastic protrusion 121. The second engaging portion 31 includes a second boss 221 provided on the first housing surface 22 and a second groove 222 provided on the second boss 221. The second recess 222 is provided on a surface of the second projection 221 facing away from the second housing face 32. In the process of unfolding the first housing component 2 and the second housing component 3, the second housing surface 32 is gradually close to the first surface 131, the second boss 221 is driven to be gradually close to the second elastic protrusion 121 until the second boss 221 abuts against the second elastic protrusion 121, along with the second housing surface 32 continuing to be close to the first surface 131, the second boss 221 extrudes the second elastic protrusion 121, and then the second elastic protrusion 121 is arranged in the second groove 222, so that the second clamping member 12 is clamped on the second clamping portion 31.

The above processes realize that the first shell component 2 and the second shell component 3 are connected with the rotating shaft component 1 into a whole when the shell is unfolded and flat.

Of course, in another embodiment, the first engaging portion 21 may be the first concave groove 212 provided on the first housing surface 22, and the second engaging portion 31 may be the second concave groove 222 provided on the second housing surface 32. In this way, in the process of flattening the first housing component 2 and the second housing component 3, the first housing surface 22 compresses the first elastic protrusion 111, the second housing surface 32 compresses the first elastic protrusion 111, and the frictional force between the first housing surface 22 and the first elastic protrusion 111 and the frictional force between the second housing surface 32 and the first elastic protrusion 111 can provide a damping feeling in the flattening process.

Referring to fig. 5 and 7, as mentioned above, the first elastic protrusion 111 is at least partially protruded on the first surface 131. When the first housing component 2 and the second housing component 3 are flat, the first surface 131 faces the first housing component 2 and the second housing component 3, so that the first elastic protrusion 111 on the first surface 131 is engaged with the first groove 212 on the first engaging portion 21 of the first housing component 2 and the second groove 222 on the second engaging portion 31. Referring to fig. 8, when the first housing element 2 is separated from the second housing element 3 and folded, the first surface 131 is located between the first housing element 2 and the second housing element 3. In other words, the end of the first casing member 2 close to the rotary shaft member 1 and the end of the second casing member 3 close to the rotary shaft member 1 are away from each other so that the first surface 131 is exposed. At this time, the outer surface of the first housing member 2, the outer surface of the second housing member 3, and the first surface 131 together form the outer surface of the foldable device 100.

Because the first elastic bulge 111 and the second elastic bulge 121 are arranged on the first surface 131 of the rotating shaft component 1, and the first surface 131 is exposed when the foldable equipment 100 is folded, when the rotating shaft component 1 falls to the ground when the foldable equipment 100 is folded, the first elastic bulge 111 and the second elastic bulge 121 can be elastically deformed under the impact force of the ground so as to buffer the impact force of the ground, and further buffer the grounding of the foldable equipment 100, and reduce the damage of the foldable equipment 100 to internal devices, the first shell component 2, the rotating shaft component 1, the second shell component 3 and the flexible display screen 4 when the foldable equipment 100 is grounded.

The foldable equipment 100 that this embodiment provided, carry out reasonable design through structure and position to first elastic bulge 111 and second elastic bulge 121, first elastic bulge 111 and second elastic bulge 121 not only play the effect of connecting first casing subassembly 2 and second casing subassembly 3, the effect of falling the buffering has still been played, the anti-hunch problem that flexible display screen 4 did not expand the production completely has effectively been solved, and the damage problem that the pivot subassembly 1 falls to land and produce when foldable equipment 100 is folded, the reliability of foldable equipment 100 complete machine and flexible display screen 4 has been promoted.

Further, referring to fig. 9, the number of the first elastic protrusions 111 and the second elastic protrusions 121 is plural. At least a portion of the first elastic protrusion 111 and at least a portion of the second elastic protrusion 121 may be located near a central axis of the rotation shaft assembly 1 to cushion the foldable device 100 when the foldable device 100 falls vertically when folded, and reduce damage to the foldable device 100. It should be noted that only one first elastic protrusion 111 is illustrated in fig. 9, and the other first elastic protrusions 111 and second elastic protrusions 121 may have the same structure as the illustrated first elastic protrusion 111, and are not illustrated in detail in fig. 9.

Further, when the first housing assembly 2 and the second housing assembly 3 are folded, at least a portion of the first elastic protrusion 111 is disposed at a position where the first surface 131 is close to the first housing assembly 2, and at least a portion of the second elastic protrusion 121 is disposed at a position where the first surface 131 is close to the second housing assembly 3, so that when the foldable device 100 is folded, the rotating shaft assembly 1 falls down obliquely to effectively buffer the foldable device 100, and damage to the foldable device 100 is reduced.

It is understood that the number and distribution of the first elastic protrusions 111 and the second elastic protrusions 121 are not limited in the present application.

The following embodiments exemplify specific structures of the first elastic lug 111 and the second elastic lug 121. Of course, the specific structure of the first elastic protrusion 111 and the second elastic protrusion 121 in the present application includes, but is not limited to, the following embodiments.

Referring to fig. 10, fig. 10 illustrates a positional relationship between the first elastic protrusion 111 and the base 13 of the rotating shaft assembly 1, and a positional relationship between the second elastic protrusion 121 and the base 13 of the rotating shaft assembly 1 can refer to a positional relationship between the first elastic protrusion 111 and the base 13, which is omitted in fig. 10.

Referring to fig. 10, the base 13 of the rotating shaft assembly 1 further has a second surface 132 opposite to the first surface 131, and a first through hole 133 penetrating through the first surface 131 and the second surface 132. One end of the first elastic protrusion 111 is disposed on the second surface 132. The middle portion of the first elastic projection 111 penetrates the first through hole 133. The other end of the first elastic protrusion 111 is protruded on the first surface 131. The first elastic protrusion 111 can be extended and contracted within the first through hole 133.

It is understood that the base 13 further has a second through hole (not shown in fig. 10), and the second surface 132 is further provided with a second elastic protrusion 121 (not shown in fig. 10, please refer to fig. 7) penetrating through the second through hole. The second via is identical in structure to the first via, differing only in location. The second elastic protrusion 121 has the same structure as the first elastic protrusion 111, and only differs in position. Although the second through hole and the second elastic protrusion 121 are not shown in fig. 10, those skilled in the art can design the structure of the second through hole and the second elastic protrusion 121 according to the structure of the first through hole 133 and the first elastic protrusion 111. Wherein, first elastic bulge 111 can stretch out and draw back in first through-hole 133, and second elastic bulge 121 can stretch out and draw back in the second through-hole to make first elastic bulge 111 little to the resistance of first casing subassembly 2 exhibition flat in-process, and second elastic bulge 121 is little to the resistance of second casing subassembly 3 exhibition flat in-process, improves the smooth and easy degree that foldable equipment 100 was opened up flat.

Referring to fig. 10, the first elastic protrusion 111 includes a pressing portion 112, an elastic portion 113 and a protrusion 114. The pressing portion 112 is fixed to the second surface 132. One end of the projection 114 abuts the second surface 132. The other end of the projection 114 protrudes out of the first surface 131 through the first through hole 133. The elastic portion 113 elastically abuts between the pressing portion 112 and the protruding portion 114. The first elastic protrusion 111 has the same structure as the second elastic protrusion 121, and a person skilled in the art can clearly understand the structure of the second elastic protrusion 121 by explaining the structure of the first elastic protrusion 111.

Specifically, referring to fig. 10 to 12, the elastic portion 113 may be a pressing spring, the pressing portion 112 may be a spring pressing plate, and the protrusion 114 includes an extending buckle 116 connecting the pressing plate 115 to the pressing plate 115. Referring to fig. 12, a thickening table 135 is disposed on the base 13 to increase the thickness of the base 13. For the sake of description, the surface of the thickening stage 135 facing away from the base 13 is considered to belong to the first surface 131. The first through hole 133 penetrates the thickening stage 135. The first through hole 133 includes an upper through hole 136 and a lower through hole 137 which are communicated with each other, the aperture of the upper through hole 136 is larger than that of the lower through hole 137, and the inner wall of the upper through hole 136 is connected with the inner wall of the lower through hole 137 by a step surface 138. The abutting plate 115 is provided in the upper through hole 136 and abuts against the step surface 138. One part of the extension buckle 116 is arranged in the lower through hole 137, and the other part of the extension buckle extends out of the first surface 131 from the lower through hole 137. The extension buckle 116 is used for being clamped in the first groove 212.

Referring to fig. 12, the pressing portion 112 is fixed on the thickening table 135. One end of the elastic portion 113 abuts against the pressing portion 112, and the other end abuts against the abutting plate 115, and the elastic portion 113 is in a compressed state.

Referring to fig. 12, when the first housing assembly 2 and the second housing assembly 3 are unfolded, the first protrusion 211 on the first housing assembly 2 is close to the extension buckle 116 and abuts against the extension buckle 116, the extension buckle 116 compresses the elastic portion 113 under the action of the first protrusion 211, the elastic portion 113 is compressed, the extension buckle 116 retracts into the first through hole 133, when the first groove 212 on the first protrusion 211 aligns with the first through hole 133, the extension buckle 116 no longer receives the pressure of the first protrusion 211, and extends into the first groove 212 under the restoring force of the elastic portion 113, thereby achieving the engaging connection between the first engaging member 11 and the first engaging portion 21. Similarly, the second clip 12 can be engaged with the second engaging portion 31.

When the foldable device 100 is in the folded state, the extension buckle 116 protrudes from the first surface 131 of the spindle assembly 1, and when the foldable device 100 is accidentally dropped, the first surface 131 of the spindle assembly 1 is grounded downwards, and the extension buckle 116 is firstly contacted with the ground. When the end face of the extension buckle 116 receives the impact force from the ground, the elastic part 113 contracts inwards to provide a buffer effect for the rotating shaft assembly 1 and the foldable device 100, so that the impact force on the rotating shaft assembly 1 and the flexible display screen 4 is reduced, and the damage to the flexible display screen 4 is reduced.

The protruding portion 114 is not limited in the present application, and the material of the protruding portion 114 includes, but is not limited to, elastic plastic, elastic rubber, metal, and the like.

Of course, in other embodiments, the first elastic protrusion 111 may be fixed on the first surface 131 without penetrating through the base 13. In this embodiment, the material of the first elastic protrusion 111 may be elastic plastic, elastic rubber, or the like.

In the embodiment where the first through hole 133 is formed in the base 13 and the first elastic protrusion 111 penetrates through the first through hole 133, the first through hole 133 is formed in the base 13, which may cause water and dust to easily enter the rotating shaft assembly 1 through the first through hole 133, thereby affecting electronic circuits and the like inside the foldable device 100.
