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.
Referring to fig. 1, an electronic device 500 is provided in the present embodiment, where the electronic device 500 may be, but is not limited to, an electronic device such as a mobile phone, a tablet computer, and a smart watch. The electronic device 500 of the present embodiment is described by taking a mobile phone as an example.
Referring to fig. 1 and fig. 2, the electronic device 500 includes an electronic component 400, a housing component 300, a foldable screen 200 and a hinge mechanism 100, wherein the electronic component 400 and the hinge mechanism 100 are disposed in the housing component 300, and the foldable screen 200 is laid on the housing component 300 and the hinge mechanism 100. The housing assembly 300 and the foldable screen 200 can be folded or unfolded through the hinge mechanism 100, and when the housing assembly 300 and the foldable screen 200 are folded, the volume of the electronic device 500 is relatively small, which is convenient for storage and carrying.
The housing assembly 300 includes a first housing 303 and a second housing 305, and the first housing 303 and the second housing 305 are respectively connected to both sides of the rotation shaft mechanism 100. The second housing 305 is foldable or unfoldable with respect to the first housing 303. The housing assembly 300 is used to carry the foldable screen 200 while shielding the electronic assembly 400. The first case 303 and the second case 305 support both ends of the foldable screen 200, respectively. The hinge mechanism 100 can be folded or unfolded and supports a portion of the flexible display 201 between the two ends. In one embodiment, the first housing 303 may be a hard housing, and the second housing 305 may also be a hard housing. The first case 303 and the second case 305 may stably support both ends of the flexible display 201.
The hinge mechanism 100 is deformable as the second housing 305 is folded or unfolded with respect to the first housing 303, and restricts the second housing 305 from being detached from the first housing 303, and the hinge mechanism 100 is also used to support the foldable screen 200 to prevent the foldable screen 200 from collapsing. Opposite two side edges of the rotating shaft mechanism 100 are respectively connected to the first housing 303 and the second housing 305. The hinge mechanism 100 utilizes its own rotatable feature to enable the first housing 303 to be turned over relative to the second housing 305, such that the first housing 303 is folded, or angled, or unfolded relative to the second housing 305.
Referring to fig. 3 to 5, the rotating shaft mechanism 100 includes a rotating shaft assembly 10 and a guiding assembly 30, the rotating shaft assembly 10 is connected to the housing assembly 300, and the guiding assembly 30 is connected to the rotating shaft assembly 10.
The spindle assembly 10 includes a fixed member 12, a spindle bracket 14, and a swivel arm 16. The fixing member 12 is disposed between the first housing 303 and the second housing 305, and is used for mounting the rotating arm 16. The pivot bracket 14 is generally juxtaposed with the stationary member 12 and is adapted to couple the pivot arm 16 and the guide assembly 30.
The two rotating arms 16 are respectively rotatably connected to the opposite ends of the rotating shaft bracket 14. In the embodiment shown in fig. 5 in particular, the two swivel arms 16 comprise a first swivel arm 161 and a second swivel arm 163. One end of the first rotating arm 161 is disposed between the fixed member 12 and the rotating shaft bracket 14, and is rotatably connected to the fixed member 12. The other end of the first rotation arm 161 extends away from the rotation shaft support 14 and is connected to the first housing 303. One end of the second rotating arm 163 is disposed between the fixed member 12 and the rotating shaft bracket 14, and is rotatably connected to the fixed member 12, and the other end of the second rotating arm 163 extends in a direction away from the rotating shaft bracket 14 and is connected to the second housing 305. The first rotating arm 161 and the second rotating arm 163 can rotate relative to the rotating shaft support 14 and the fixing member 12 under the action of external force to be close to each other to be in a folded state, or to be away from each other to be in an unfolded state, so that the first housing 303 and the second housing 305 can be relatively smoothly folded or unfolded.
The guiding assembly 30 is movably connected to the rotating shaft bracket 14 and is used for guiding the folding state of the foldable screen 200 so that the foldable screen 200 is bent and deformed towards a predetermined direction in the folding state to prevent the foldable screen 200 from being abnormally arched or bent and deformed when being folded. The guiding assembly 30 includes a guiding element 32 and an elastic element 34, wherein the guiding element 32 is disposed between the rotating shaft bracket 14 and the fixing element 12, and the elastic element 34 is disposed between the guiding element 32 and the elastic element 34.
Further, the guide member 32 is movably engaged with the rotation shaft bracket 14 and can slide relative to the rotation shaft bracket 14 along a direction limited by the rotation shaft bracket 14. The guiding element 32 abuts against the first rotating arm 161 or/and the second rotating arm 163, and when the first rotating arm 161 or/and the second rotating arm 163 rotate relative to the rotating shaft bracket 14 and approach each other, the first rotating arm 161 or/and the second rotating arm 163 pushes the guiding element 32, so that the guiding element 23 protrudes out of the rotating shaft bracket 14 (e.g., protrudes out of the side of the rotating shaft bracket 14 away from the fixing element 12).
The guide 32 includes a body 321 and a guide part 323 connected to the body 321.
In the embodiment shown in fig. 5, the body 321 is substantially triangular block-shaped and is provided with a driven surface 3211 (fig. 3), the driven surface 3211 is provided on the side of the body 321 facing the fixing member 12 and abuts against the first rotating arm 161 or/and the second rotating arm 163, so that the first rotating arm 161 or/and the second rotating arm 163 can abut against the driven surface 3211 to drive the guide 32 to move. Wherein the guide 32 is slidable in a direction generally parallel to the axis of rotation of the swivel arm 16 when slidably engaged with the swivel bracket 14.
In the present embodiment, the driven surface 3211 is substantially planar and is disposed obliquely with respect to the sliding direction of the guide 32, that is, the driven surface 3211 forms an angle (e.g., acute angle) with the sliding direction of the guide 32. Further, the number of the driven surfaces 3211 is two, and the two driven surfaces 3211 include a first driven surface 3213 and a second driven surface 3215. In some embodiments, the first driven surface 3213 is connected to the second driven surface 3215 to form a predetermined included angle therebetween, which may be an obtuse angle.
Further, a first driven surface 3213 and a second driven surface 3215 are disposed substantially symmetrically on the body 321, and the first driven surface 3213 is disposed on a side of the body 321 close to the first rotating arm 161 and abuts against the first rotating arm 161; the second driven surface 3215 is disposed on the side of the body 321 close to the second rotating arm 163, and abuts against the second rotating arm 163. When the two rotating arms 16 rotate relative to the spindle bracket 14, the rotating arms 16 respectively produce relative sliding on the corresponding driven surfaces 3211 to thereby push the guide member 32 to slide relative to the spindle bracket 14. It is understood that in other embodiments, the number of the driven surfaces 3211 may be one, and one driven surface 3211 may abut against any one of the two rotating arms 16, so that the rotating arm 16 can push the driven surface 3211 to drive the guide 32 to move.
The guiding portion 323 is disposed on a side of the body 321 departing from the driven surface 3211, and is in sliding fit with the rotating shaft bracket 14, so that when the guiding member 32 slides relative to the rotating shaft bracket 14, the guiding portion extends from a side of the rotating shaft bracket 14 departing from the body 221, thereby guiding a deformation direction of the foldable screen 200 and preventing the foldable screen 200 from being deformed due to arching. In the present embodiment, the guiding portion 323 substantially protrudes from the surface of the body 321 to form a convex column structure, and the guiding portion 323 movably penetrates through the rotating shaft bracket 14.
In order to limit the sliding direction of the guide part 323, the rotation shaft bracket 14 is provided with a through hole 141, the axial direction of the through hole 141 is substantially parallel to the rotation axis of the rotation arm 16, and the through hole 141 penetrates the rotation shaft bracket 14, and the guide part 323 movably protrudes into the through hole 141. It will be appreciated that in other embodiments, the through hole 141 of the spindle bracket 14 may be replaced by other forms of guide structures, for example, the spindle bracket 14 may be provided with a guide groove with which the guide portion 323 slidably mates; alternatively, the guide 323 and the bracket of the rotating shaft bracket 14 may be slidably engaged by a guide rail and a guide groove.
The elastic member 34 is disposed between the body 321 and the rotation shaft support 14, and is used for providing a restoring force for the movement of the guide member 32. Specifically, in the present embodiment, the elastic members 34 are coil springs, and the number of the elastic members 34 is two, and the two elastic members 34 are respectively provided on both sides of the guide portion 323. The two ends of the elastic element 34 respectively abut against the body 321 and the rotating shaft bracket 14, and apply a pushing force to the body 321 away from the rotating shaft bracket 14. When the two rotating arms 16 rotate relative to the rotating shaft bracket 14 and approach each other, the body 321 is driven by the rotating arms 16 to approach the rotating shaft bracket 14, so that the guide part 323 protrudes out of the rotating shaft bracket 14 through the through hole 141, and the elastic member 34 is compressed. When the two rotating arms 16 rotate relative to the rotation shaft holder 14 and move away from each other, the elastic member 34 is restored to be deformed and applies an elastic restoring force to the body 321, so that the body 321 moves away from the rotation shaft holder 14 while the guide 323 retracts and returns into the through hole 141.
In order to effectively position the elastic element 34 and prevent the elastic element 34 from deviating during deformation, the guide element 32 further includes a positioning portion 325, the positioning portion 325 is a convex column structure connected to the body 321, and the elastic element 34 is sleeved on the positioning portion 325. Further, in some embodiments, the rotating shaft bracket 14 may further have a positioning hole (not shown) corresponding to the positioning portion 325, the positioning hole may be a blind hole structure, and is disposed substantially coaxially with the positioning portion 325, one end of the elastic member 34 is sleeved on the positioning portion 325, and the other end is received in the positioning hole.
Referring to fig. 4 and fig. 6, in the present embodiment, the rotating shaft bracket 14 further has a receiving groove 143, the receiving groove 143 is opened on a side of the rotating shaft bracket 14 facing the fixing member 12, and the receiving groove 143 is used for receiving the guiding member 32 and providing sufficient movement space for the guiding member 32, so that the structure of the rotating shaft mechanism 100 is more compact. In the illustrated embodiment, the guide member 32 and the elastic member 34 are disposed in the receiving groove 143.
Referring to fig. 2 and fig. 3 again, in the present embodiment, when the rotating shaft mechanism 100 is disposed in the housing assembly 300, it is connected between the first housing 303 and the second housing 305. In order to make the first housing 303 and the second housing 305 uniformly stressed during rotation, two rotating shaft assemblies 10 and two guiding assemblies 30 are provided, the two rotating shaft assemblies 10 are respectively disposed at two side edges of the housing assembly 300, for example, one of the rotating shaft assemblies 10 may be disposed at a top side of the housing assembly 300, the other rotating shaft assembly 10 may be disposed at a bottom side of the housing assembly 300, and meanwhile, the two guiding assemblies 30 and the two rotating shaft assemblies 10 are disposed in one-to-one correspondence. Thus, when the housing assembly 300 is folded, the first housing 303 and the second housing 305 can rotate around the stable rotation shaft, which is beneficial to improving the stability of the electronic device 500 and improving the operation hand feeling of the user. It should be understood that the top side described above refers to a portion near the top edge of the electronic device 500 and the bottom side refers to a portion near the bottom edge of the electronic device 500, with reference to the more common placement of the electronic device 500 during use.
Further, in the present embodiment, the rotating shaft mechanism 100 further includes a screen supporting member 50, and the screen supporting member 50 extends along the inside of the housing member 300, and both ends thereof are respectively connected to the two rotating shaft members 10. The screen support assembly 50 is used to support the foldable screen 200. In the present embodiment, the screen support assembly 50 includes a first support 52 and a second support 54.
Referring to fig. 3 and 5, the first supporting member 52 is substantially a plate-shaped structure, and is connected to the rotating shaft bracket 14 through a rotating shaft 521, and can rotate relative to the rotating shaft bracket 14. One side of the first supporter 52 away from the rotating shaft 521 is movably connected to the first rotating arm 161 to enhance the structural stability of the first supporter 52. Further, a first connecting portion 523 is disposed at a side of the first supporter 52 close to the first rotating arm 161, and the first connecting portion 523 is movably connected to the first rotating arm 161. Accordingly, the first rotation arm 161 is provided with a first guide groove 1611, and the first connecting portion 523 movably protrudes into the first guide groove 1611 and can slide along the extending direction of the first guide groove 1611. In the present embodiment, the first connecting portion 523 has a substantially fan-shaped block shape, and the first guide groove 1611 has a substantially fan-shaped hole shape, and penetrates the first rotating arm 161 substantially along the rotating shaft direction of the rotating shaft 521. The arc of the sector of the first guide groove 1611 is greater than the arc of the sector of the first connecting portion 523, so that the first connecting portion 523 can slide along the arc of the sector in the first guide groove 1611. When the first rotating arm 161 drives the first support 52 to rotate relative to the rotating shaft bracket 14, the first connecting portion 523 rotates adaptively in the first guiding groove 1611 to avoid movement interference, increase the flexibility of the rotating shaft mechanism 100, and support the foldable screen 200.
The second supporting member 54 is substantially the same as the first supporting member 52, and is pivoted to the pivot bracket 14 via a pivot 541, and is movably connected to an end of the second rotating arm 163 away from the pivot bracket 14. The end of the second rotating arm 163 away from the rotating shaft bracket 14 is provided with a second guiding groove 1631, the second supporting member 54 is provided with a second connecting portion 543, and the second connecting portion 543 movably protrudes into the second guiding groove 1631.
Further, in the present embodiment, the rotating shaft mechanism 100 further includes a supporting plate 70, and the supporting plate 70 is disposed between the first supporting member 52 and the second supporting member 25 and connected to the rotating shaft support 14. The supporting plate 70 is used for supporting the foldable screen 200 and forms a receiving space, so that when the foldable screen 200 is folded, there is enough space for generating a deformation in a predetermined direction. In the embodiment shown in fig. 5 in particular, the supporting plate 70 is a substantially plate-shaped structure having a recess, which extends along the inside of the housing assembly 300, and both ends of which are connected to the two rotating shaft assemblies 10, respectively. Further, the support plate 70 is connected to the rotation shaft bracket 14, and at this time, the through hole 141 of the rotation shaft bracket 14 is positioned above the surface of the support plate 70, that is, the axis of the through hole 141 and the axis of the guide portion 323 are disposed substantially in parallel with the support plate 70, so that the guide portion 323 of the guide member 32 can be positioned above the support plate 70 after protruding out of the through hole 141 (e.g., the guide portion 323 is spaced apart from the support plate 70) to guide the bending direction of the foldable screen 200 disposed on the support plate 70.
Further, a concave surface 72 is formed on one side of the supporting plate 70 close to the through hole 141, and the concave surface forms a receiving portion 74, and the receiving portion 74 provides a sufficient deformation space for the foldable screen 200. In this embodiment, the concave surface 72 is substantially in the shape of a portion of an inner cylinder extending along the surface of the support plate 70 to accommodate the folded shape of the foldable screen 200.
