All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic perspective view of an electronic device according to a first embodiment of the present invention. The electronic apparatus 100 includes a first housing 101, a second housing 102, and a flexible device 103. The flexible device 103 is fixedly mounted on the first frame 101 and the second frame 102, and the first frame 101 and the second frame 102 are used for supporting and protecting the flexible device 103.
In this embodiment, the electronic device 100 is a mobile phone. It is to be appreciated that in other embodiments, the electronic device 100 may be, but is not limited to, a radiotelephone, a tablet, a gaming machine, a reader, a pager, a Web browser, a notepad, a calendar, and/or a Personal Digital Assistant (PDA) for a Global Positioning System (GPS) receiver.
Referring to fig. 2, fig. 2 is a partial cross-sectional view taken along line II-II of fig. 1. The flexible device 103 comprises a flexible screen 10, a support sheet 30 and a hinge 50. The flexible screen 10 comprises a bendable region 11. The supporting sheet 30 is fixed to the bendable region 11. The hinge 50 is attached to the side of the support sheet 30 facing away from the flexible screen 10 by glue 60.
Because the hinge 50 is fixedly connected with the support sheet 30 through the colloid 60, the flexible screen 10 is not easy to generate the phenomenon of uneven local stress on the surface, and the flatness of the flexible screen 10 is improved. In addition, the glue dispensing equipment is generally adopted for automatic glue dispensing, and compared with an operation mode of manually locking a screw for fixing, the glue dispensing equipment is beneficial to reducing materials and production cost and improving production efficiency.
In this embodiment, the flexible screen 10 is a flexible display screen, the bendable region 11 is a local region of the flexible screen 10, and the bendable region 11 is located at a substantially middle position of the flexible screen 10. It is understood that the flexible screen 10 may be a flexible touch screen, a flexible touch display screen; the bendable region 11 is not limited to be disposed in the middle of the flexible screen 10, and the whole region of the flexible screen 10 may be the bendable region 11.
The support sheet 30 is stacked with the flexible screen 10. The supporting sheet 30 is fixed to the bendable region 11 of the flexible screen 10 for supporting the bendable region 11 to prevent the bendable region 11 of the flexible screen 10 from arching. The support sheet 30 has elastic deformability. In the present embodiment, the support sheet 30 is a steel sheet. The side of the flexible screen 10 facing away from the support sheet 30 is a display side. It is understood that the supporting plate 30 is not limited to be a steel plate, and the supporting plate 30 may be made of other materials with certain elasticity, such as an elastic plastic plate. The support sheet 30 includes a first surface 31 and a second surface 33 opposite to each other, wherein the first surface 31 is disposed toward the flexible screen 10 and is fixedly connected to the flexible screen 10.
Further, the flexible panel 10 includes a panel body 15 and a protective layer 17 which are stacked. The protective layer 17 is fixedly connected to the first surface 31 for protecting the screen body 15 and preventing the supporting sheet 30 from wearing the screen body 15. In this embodiment, the protective layer 17 is a liquid metal sheet, and the liquid metal sheet is fixedly attached to the back surface of the screen body 15. The term liquid metal refers to an alloy which is heated to a molten state and then cooled at an ultra-fast cooling rate to solidify the alloy crystal lattice in a state of not being as well aligned as a glass, and is also referred to as an amorphous alloy, a liquid metal or a metallic glass. The liquid metal has the characteristics of long-range disorder (short-range order), metastable state, certain physical property isotropy, no definite melting point, glass transition temperature point and the like, has the characteristics of solid state, metal and glass, and can have high strength, high hardness, plasticity, heat conduction, wear resistance and the like under certain conditions. That is, the liquid metal is substantially solid at normal temperature, but has some properties close to those of liquid, and is therefore referred to as a liquid metal.
In other embodiments, the material of the protective layer 17 is not limited, for example, the protective layer 17 may be a wear-resistant plastic sheet or a wear-resistant rubber sheet fixedly attached to the back surface of the screen body 15.
The hinge 50 is bonded to the second surface 33 of the support sheet 30 on the side facing away from the flexible screen 10 by a glue 60 for bending and unfolding the flexible screen 10. The hinge 50 is located between the first frame 101 and the second frame 102.
When the flexible screen 10 of the electronic device 100 is bent or unfolded through the hinge 50, the hinge 50 can slide relative to the second surface 33, and the gel 60 is elastically deformed, that is, the gel 60 generates an acting force that pulls the hinge 50 toward the support sheet 30, so that the support sheet 30 and the hinge 50 are kept close to each other, and the possibility that the hinge 50 is separated from the support sheet 30 is reduced, thereby preventing the flexible screen 10 from arching due to the separation of the hinge 50 and the support sheet 30, and improving the flatness of the flexible screen 10.
In other words, when the flexible screen 10 of the electronic device 100 is bent or unfolded by the hinge 50, the supporting sheet 30 slides relative to the hinge 50, and the gel 60 is stretched and deformed when the supporting sheet 30 slides relative to the hinge 50, that is, the gel 60 can be stretched and deformed like a rubber band to compensate for the arc length of the hinge 50 when moving relative to the supporting sheet 30.
In the present embodiment, the colloid 60 is an elastic colloid formed by curing organic silica gel glue. It can be understood that the glue 60 is not limited to be formed by curing the organic silicon glue, but may also be an elastic glue formed by curing a photosensitive glue, and in an embodiment, after the dispensing of the photosensitive glue on the hinge 50 by the dispensing device is completed, the photosensitive glue can be cured by ultraviolet light irradiation, and at this time, the photosensitive glue is cured into an elastic solid glue.
Due to the elasticity of the gel 60, it can be deformed in tension when the hinge 50 slides relative to the support sheet 30. When the relative position of the hinge 50 and the supporting sheet 30 is restored, the gel 60 will automatically contract and deform to restore the original state due to its own elasticity, and will not be pulled apart.
In one embodiment, the deformation degree of the gel 60 is proportional to the sliding distance of the hinge 50 relative to the support sheet 30, i.e. c is satisfied2＝a 2+b 2Where c is the length of the gel 60 after being stretched and deformed, a is the sliding distance of the hinge 50 with respect to the support sheet 30, and b is the distance between the hinge 50 and the support sheet 30 in the thickness direction. In other words, the stretching width of the gel 60 satisfies the setting: assuming that the sliding direction of the hinge 50 with respect to the support sheet 30 is X and the thickness direction of the support sheet 30 is Y, when the hinge 50 slides with respect to the support sheet 30, the gel 60 is stretched and deformed in a direction inclined with respect to both the X and thickness directions Y.
The hinge 50 is provided with a plurality of dispensing holes 51 disposed through the hinge 50 for receiving the glue 60. The dispensing hole 51 includes a first opening 511 and a second opening 513 that are disposed in communication, wherein the first opening 511 is an opening of the dispensing hole 51 facing the supporting sheet 30, and the second opening 513 is an opening of the dispensing hole 51 facing away from the supporting sheet 30. The elastic gel 60 in the dispensing hole 51 is adhered to the second surface 33 of the support sheet 30 facing the hinge 50 through the first opening 511. In this embodiment, the diameter of the first opening 511 is smaller than that of the second opening 513. During dispensing, the dispensing needle of the dispensing device extends into the second opening 513 for dispensing, the glue flows out from the first opening 511 to the support sheet 30, and the glue is cured to form the glue 60 for adhering the inner wall of the dispensing hole 51 and the support sheet 30.
In the present embodiment, the glue 60 does not fill the entire dispensing hole 51 and does not fill the first opening 511. It is understood that the gel 60 may fill the entire gel dispensing aperture 51. It is understood that the glue 60 may fill the first opening 511 to prevent impurities such as dust from entering between the supporting plate 30 and the hinge 50 through the first opening 511, which may affect the flatness of the flexible screen 10.
Since the glue is dispensed through the second opening 513 concavely arranged on the side of the hinge 50 departing from the support sheet 30, the glue dispensing operation of the glue dispensing device is facilitated, and the glue overflow is prevented from polluting the rest area of the hinge 50. Since the dispensing hole 51 penetrates through the hinge 50, the contact area between the gel 60 and the support sheet 30 can be controlled by controlling the caliber of the first opening 511 facing one end of the support sheet 30, the deformation amount of the connection sheet 60 during stretching deformation can be prevented, the support sheet 30 can be prevented from being separated from the hinge 50, and the flexible screen 10 can not be arched.
Referring to fig. 3, fig. 3 is a schematic diagram of an omitted structure of an electronic device according to an embodiment of the invention. The hinge 50 includes a first region 501 and two second regions 503. The first region 501 is located between two second regions 503. The first regions 501 are located approximately in the middle of the hinge 50 and each second region 503 is located approximately at an end of the hinge 50.
A plurality of glue holes 51 are located in a first region 501 of the hinge 50. In the present embodiment, the hinge 50 is rotatably bendable about an axis parallel to the first direction, and the longer side of the second opening 513 extends in the first direction and the shorter side of the second opening 513 extends in the second direction perpendicular to the first direction. The first opening 511 is substantially bar-shaped, and the longer edge of the first opening 511 extends along a second direction perpendicular to the first direction, which is beneficial to releasing the stress generated by the hinge 50 when the flexible screen 10 is bent or unfolded, thereby prolonging the service life of the hinge 50. The length of the longer side of the penetration part 513 is substantially the same as the length of the shorter side of the accommodation part 511. It is understood that the shapes of the first opening 511 and the second opening 513 are not limited, and may be circular, triangular, and other shapes.
The hinge 50 has a plurality of first through holes 55 formed through the second region 503, and the electronic device 100 further includes a plurality of first locking members 70. Each locking member 70 is fixedly coupled to the support plate 30 through a first through hole 55. In this embodiment, the locking member 70 is a screw. When the flexible screen 10 of the electronic device 100 is bent or unfolded through the hinge 50, the hinge 50 slides relative to the second surface 33, and the locking member 70 can generate a force for pulling the hinge 50 toward the supporting sheet 30, so that the supporting sheet 30 and the hinge 50 are kept close to each other, and the possibility that the hinge 50 is separated from the supporting sheet 30 is reduced, thereby preventing the flexible screen 10 from arching due to the separation of the hinge 50 and the supporting sheet 30, and improving the flatness of the flexible screen 10.
It is understood that, without limiting the distribution area of the dispensing holes 51, the dispensing holes 51 may be distributed in the first area 501, the second area 503 and/or other areas of the hinge 50, so that the hinge 50 and the support sheet 30 are bonded by the glue 60.
It is understood that the locking member 70 may be omitted, and the glue 60 may be formed by dispensing the glue into the first through hole 55, and the glue 60 in the first through hole 55 is adhered to the inner wall of the first through hole 55 and the supporting plate 30.
It can be understood that please refer to fig. 4, fig. 4 is a schematic sectional view of a hinge according to an embodiment of the present invention. The hinge 50 is provided with a plurality of second through holes 57 penetrating through the first region 501, the flexible device further comprises a second locking member 80, and the second locking member 80 penetrates through the second through holes 57 and is fixedly connected with the support sheet. The second through holes 57 are spaced apart from the dispensing hole 51. The hinge 50 is fixed to the support plate 30 by means of two ways, i.e., gluing with the glue 60 and locking with the locking member 70.
Referring to fig. 5, fig. 5 is a partial cross-sectional view of a flexible device according to a second embodiment of the present invention. The flexible device provided by the second embodiment has substantially the same structure as the flexible device provided by the first embodiment, except that the dispensing hole 51 is recessed on the side of the hinge 50 facing the support sheet 30, and the dispensing hole 51 is not a through hole.
Referring to fig. 6, fig. 6 is a schematic cross-sectional view of a flexible device according to a third embodiment of the present invention. The flexible device provided by the third embodiment has substantially the same structure as the flexible device provided by the first embodiment, except that the second surface 33 of the support sheet 30 has a groove 331 for receiving the gel 60. The dispensing device dispenses the glue into the dispensing hole 51 through the second opening 513, and the glue flows into the groove 33 from the first opening 511, so as to bond the hinge 50 with the support sheet 30. Since the second surface 33 has the groove 331 for accommodating the glue 60, the glue 60 is prevented from entering other areas of the second surface 33, which causes unevenness between the hinge 50 and the supporting sheet 30, and is beneficial to improving the flatness of the flexible screen.
It is understood that the dispensing hole 51 may be omitted, and the side of the supporting sheet 30 facing the hinge 50 is coated with glue, and/or the side of the hinge 50 facing the supporting sheet 30 is coated with glue, which is solidified to form a solid glue 60, so as to connect the supporting sheet 30 and the hinge 50.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
