Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. 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 and 2, the present invention discloses an electronic device including:

the device comprises a device body 1, a fluid bag 2 and a flexible screen 3, wherein the device body 1 comprises a first body 101 and a second body 102, and a first gap 103 is formed between the first body 101 and the second body 102; at least a portion of the fluid cell 2 is disposed in the first gap 103, the fluid cell 2 has a fluid therein, and the fluid cell 2 includes a first fluid cell 202 and a second fluid cell 203 that are communicated with each other. The fluid bladder 2 with fluid may just fill the first gap 103, or may protrude from the first gap 103 when the space of the first gap 103 becomes smaller or insufficient. The flexible screen 3 is arranged on the device main body 1, the flexible screen 3 includes a bending portion 301 and a first fixing portion and a second fixing portion respectively connected with the bending portion 301, the first fixing portion and the second fixing portion can be oppositely arranged on two sides of the bending portion 301, the first fixing portion is fixedly connected with the first main body 101, the second fixing portion is fixedly connected with the second main body 102, the first fluid bag 202 is close to the flexible screen 3 and abuts against the bending portion 301, and the second fluid bag 203 is arranged far away from the flexible screen 3;

the states of the flexible screen 3 include an expanded state and a bent state, when the flexible screen 3 is in the expanded state, a fluid is located in the first fluid bag 202, or a large amount of fluid is located in the first fluid bag 202, and the first fluid bag 202 is supported by the bent portion 301. The first fluid bladder 202 can support the bent portion of the flexible screen 3 so that the bent portion does not collapse. On the other hand, the first fluid bladder 202 and the bending part 301 may be connected. Wherein, the connection mode can be bonding, hinging and the like. The present application is not particularly limited as to the manner of connection. The first fluid bladder 202 can pull the folded portion 301 when the flexible screen 3 is unfolded, and prevent the folded portion 301 from curling up. When the flexible screen 3 is in a bent state, the first body 101 and the second body 102 are bent with the first gap 103, the first body 101 and the second body 102 approach each other, after the first fluid bag 202 is pressed by the first body 101 and the second body 102, the fluid in the first fluid bag 202 flows to the second fluid bag 203, and the second fluid bag 203 may protrude from edges of the first body 101 and the second body 102. Under the condition that the second fluid bag 203 protrudes out of the edges of the first body 101 and the second body 102, the space of the electronic equipment is not occupied, and devices in the electronic equipment are not pressed, so that the volume of the electronic equipment in the design process can be reduced, the normal operation of the devices in the electronic equipment is protected, and the devices in the electronic equipment are effectively prevented from being damaged due to pressing. When the flexible screen 3 is in the bent state, the pressure of the fluid in the first fluid bag 202 is increased due to the decrease of the space of the first fluid bag 202, and the first fluid bag 202 can also have a good supporting function on the bent portion 301, thereby effectively preventing the bent portion 301 from curling and arching due to the bent state.

Specifically, the first body 101 and the second body 102 may be formed by integrally forming a flexible material into the device body 1, may also be designed in a split manner and are both connected to the flexible screen 3, or the first body 101 and the second body 102 are connected by a flexible material, which is not limited in the present invention.

Optionally, the fluid includes at least one of a gas and a liquid, and the pressure of the fluid is not less than atmospheric pressure.

Specifically, the fluid may be a gas, such as helium, neon, argon, etc., which are inert gases, and due to the greater compressibility of the gas, the pressure of the fluid may be in a range of 0.12-0.5MPa, preferably 0.15-0.4MPa, in order to ensure that the fluid in the fluid bladder 2 can always maintain sufficient support for the bent portion 301 of the flexible screen 3; in addition, the fluid may be a liquid, such as water, a safe and cheap liquid with a high ignition point, such as ethylene glycol and glycerol, and the pressure of the fluid may be in the range of 0.10-0.2MPa, preferably 0.12-0.18MPa due to the low compressibility of the liquid, so that the service life of the fluid bladder 2 may be prolonged in a low pressure state while ensuring sufficient support of the bent portion 301 of the flexible screen 3 by the fluid in the fluid bladder 2.

Optionally, a folding angle of the bent portion 301 ranges from 0 ° to 180 °, and the folding angle is specifically an included angle between the first main body 101 and the second main body 102. The user can open the electronic equipment into a designated angle by himself according to needs, so that the user operation is facilitated.

The folding range of the folding part 301 directly affects the user experience of the foldable electronic device. The fluid bag 2 can always keep enough support for the bending part 301 of the flexible screen 3 in the bending state or even in the unfolding state of the flexible screen 3, so that the folding angle of the bending part 301 can be bent from 180 degrees in the unfolding state to 0 degree in the maximum bending state, the use experience of a user is improved, and meanwhile, the occupied area of electronic equipment is reduced.

Alternatively, referring to fig. 1, said first body 101 and second body 102 are symmetrically arranged with respect to said first gap 103, i.e. the first body 101 and second body 102 are identical. Under the condition that the flexible screen 3 of the electronic device is in a bent state, the first main body 101 and the second main body 102 are completely overlapped, so that the size of the electronic device is effectively reduced, and meanwhile, the flexible screen has higher practicability.

In addition, in the case where the flexible screen 3 is in the unfolded state, the space of the first gap 103 may be equal to the volume of the fluid bladder 2, that is, the fluid bladder 2 is completely disposed in the first gap 103. This can promote the outward appearance uniformity of electronic equipment.

Specifically, the symmetry plane of the bending portion 301 is a plane a-a in fig. 1, that is, the bending symmetry plane when the bending portion 301 bends, and since the fluid bladder 2 is filled with the first gap 103, in the process of bending the bending portion 301, the first main body 101 and the second main body 102 which are symmetrically arranged can symmetrically extrude and deform the fluid bladder 2, so that the fluid bladder 2 can symmetrically and comprehensively support the bending portion 301, the stress of the whole bending portion 301 can be reduced, and the damage to the flexible screen 3 caused by stress concentration can be avoided.

Optionally, with the flexible screen 3 in the expanded state, the volume of the first fluid bladder 202 is greater than the volume of the second fluid bladder 203, i.e. fluid is mainly concentrated in the first fluid bladder 202, enabling the first fluid bladder 202 to support the flexible screen. With the flexible screen 3 in a bent state, the volume of the first fluid bladder 202 is smaller than the volume of the second fluid bladder 203. The fluid in the first fluid bladder 202 flows to the second fluid bladder 203 due to the compression of the first fluid bladder 202 by the flexible screen 3 being flexed, and therefore the volume of the first fluid bladder 202 is less than the volume of the second fluid bladder 203.

Specifically, in the unfolded state of the flexible screen 3, the cross-sectional shape of the first gap 103 may be a shape similar to a wedge, which has a characteristic that the area close to the flexible screen 3 is larger than the area far from the flexible screen 3, so as to facilitate the support of the bent portion 301 by a larger part of the upper end of the fluid bag 2 during the compression deformation, where the volume of the first fluid bag 202 is larger than the volume of the second fluid bag 203. In the case where the flexible screen 3 is in the bent state, the cross-sectional shape of the first gap 103 may be a shape similar to a trapezoid due to the pressing of the flexible screen 3, and the cross-sectional shape may have a characteristic that an area close to the flexible screen 3 is smaller than an area far from the flexible screen 3, and after the first fluid bladder 202 is pressed by the first body 101 and the second body 102, the fluid in the first fluid bladder 202 flows to the second fluid bladder 203, and then the volume of the first fluid bladder 202 is smaller than the volume of the second fluid bladder 203.

Alternatively, referring to fig. 1 and 2, the second fluid bladder 203 may be provided in a drop shape or a laminate shape.

The drop-like or laminated arrangement may effect lateral extrusion and outward expansion of the fill fluid therein. In the case where a large amount of fluid flows into the first fluid bladder 202 or the second fluid bladder 203, the fluid bladder has good containment performance, and the problem that the electronic apparatus is broken in the unfolded or folded state can be effectively prevented. Therefore, when the flexible screen 3 is switched between the bent state and the unfolded state, the fluid filled in the fluid bag 2 can flow from the first fluid bag 202 to the second fluid bag 203 only by the external force of the bending process, so that the fluid filled in the fluid bag 2 can flow directionally while the flexible screen 3 is stably supported by the fluid bag 2, and the long-term stability of the support of the fluid bag 2 is ensured.

Optionally, referring to fig. 1 and 2, the electronic device further includes at least two magnetic members 4, the two magnetic members 4 are respectively disposed on the first body 101 and the second body 102, and a soft magnetic layer 5 attracting the magnetic members 4 is disposed on one side of the fluid bag 2 close to the flexible screen 3. The magnetic element 4 and the soft magnetic layer 5 are attracted to each other and can be used to adjust the pressure distribution and the action of the fluid in the fluid bag 2.

Specifically, when the flexible screen 3 is in the unfolded state, the fluid in the fluid bag 2 can play a good role in supporting the bent portion 301 of the flexible screen 3, so as to support the bottom area of the bent portion 301, and the supporting effect of the fluid in the fluid bag 2 on the bent portion 301 can be enhanced by combining the action of the electromagnetic force mutually attracted by the magnetic member 4 and the soft magnetic layer 5; similarly, when the flexible screen 3 is in a bent state, the flexible screen 3 can be subjected to the resultant force of the hydraulic pressure of the fluid in the fluid bag 2 and the mutually attracted electromagnetic force of the magnetic element 4 and the soft magnetic layer 5 when being in any specific bent position, so that partial stress of the bent part 301 of the flexible screen 3 in the bending process is eliminated, and the bent part 301 is effectively and uniformly supported.

Optionally, referring to fig. 1 and fig. 2, the magnetic member 4 includes a first magnetic member 41 and a second magnetic member 42, the first magnetic member 41 is disposed on the first main body 101, the second magnetic member 42 is disposed on the second main body 102, the first magnetic member 41 and the second magnetic member 42 are disposed near the bent portion 301, the first magnetic member 41 and the second magnetic member 42 are symmetrically disposed with respect to the first gap 103, and a symmetry plane of the first gap 103 is an a-a plane in fig. 1, that is, a bending symmetry plane when the bent portion 301 is bent.

Specifically, the symmetry sets up first magnetism spare 41 with second magnetism spare 42 all can with the magnetic attraction that soft magnetic layer 5 effect produced the symmetry, and then can produce right the squeezing action of fluid bag 2 symmetry, because the internal stress that kink 301 produced at the in-process of buckling is also symmetrical, so the squeezing action that the electromagnetic attraction of symmetry brought can act on kink 301, right the support that kink 301 symmetry just can reduce the internal stress that kink 301 symmetry has improved the life-span of buckling of kink 301.

Optionally, a waterproof layer is disposed on a side of the device body 1 away from the flexible screen 3, and the waterproof layer includes a telescopic portion opposite to the first gap 103. Specifically, the fluid bag 2 is filled with fluid, and in the case that the flexible screen 3 is in a bent state, the fluid bag 2 may be pressed by the first body 101 and the second body 102, and there is a risk of fluid leakage, and the waterproof layer may effectively prevent leakage of fluid. In addition, when the first body 101 and the second body 102 press the fluid bag 2, the size of the first gap 103 on the side away from the flexible screen 3 becomes larger, and the arrangement of the telescopic part just can meet the structural change of the first gap 103.

Optionally, referring to fig. 1 and 2, the electronic device further comprises an adhesive layer 6, and the fluid bladder 2 is connected with the flexible screen 3 through the adhesive layer 6.

Specifically, the adhesive layer 6 may be made of a PET film. The fluid bag 2 is bonded with the flexible screen 3 through a layer of PET film, so that the flatness of the contact surface of the fluid bag 2 and the flexible screen 3 can be ensured, the fluid bag 2 is prevented from generating wrinkles at the contact surface, and the stress damage of fluid in the fluid bag 2 to the wrinkles is avoided.

Specifically, the protective layer 7 can be made of a PI protective film, which has good high temperature resistance, insulation performance and mechanical strength, can ensure that the flexible screen 3 is not deformed and damaged in multiple bending processes, and can prevent the flexible screen 3 from being damaged by the change of the external environment temperature; in addition, the protective layer 7 may also be made of other flexible materials with temperature resistance and good mechanical strength, such as flexible ultrathin glass, OCA glue, and the like, to protect the flexible screen 3, which is not limited in the present invention.

According to the invention, the fluid bag 2 is arranged below the bent part 301 of the flexible screen 3, so that the fluid bag 2 can always keep enough support for the bent part 301 of the flexible screen 3 in a bent state or even an unfolded state of the flexible screen 3, thus stress concentration at the position of the bent part 301 can be eliminated, crease marks at the position of the bent part 301 of the flexible screen 3 can be eliminated, the bent part 301 is guaranteed to be continuously and stably supported, and the service life of the flexible screen 3 is prolonged.
