Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, 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 corresponding drawings. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

1 and 2, the present invention discloses an electronic device, including:

A device body 1, a fluid bladder 2 and a flexible screen 3, the device body 1 includes a first body 101 and a second body 102 with a first gap 103 between the first body 101 and the second body 102; The fluid bladder 2 is disposed in the first gap 103 , the fluid bladder 2 contains fluid, and the fluid bladder 2 includes a first fluid bladder 202 and a second fluid bladder 203 that communicate 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 the space is insufficient. The flexible screen 3 is disposed on the device body 1, and the flexible screen 3 includes a bending portion 301 and a first fixing portion and a second fixing portion respectively connected to the bending portion 301. The first fixing portion The first fixing part and the second fixing part can be fixedly connected to the first body 101 and the second fixing part is fixed to the second body 102 connected, 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 disposed away from the flexible screen 3 ;

The state of the flexible screen 3 includes an unfolded state and a bent state. When the flexible screen 3 is in the unfolded state, the fluid is located in the first fluid bag 202 , or most of the fluid is located in the first fluid bag 202 inside, and the first fluid bladder 202 is supported on the bending portion 301 . The first fluid bladder 202 can support the bent portion of the flexible screen 3 so that the bent portion will not collapse. On the other hand, the first fluid bladder 202 and the bent portion 301 can be connected. Wherein, the connection mode can be bonding, hinged and so on. This application does not specifically limit the connection method. When the flexible screen 3 is unfolded, the first fluid bladder 202 can pull the bending portion 301 to prevent the bending portion 301 from being curled and arched. When the flexible screen 3 is in a bent state, the first body 101 and the second body 102 are bent at the first gap 103 , the first body 101 and the second body 102 102 are close to each other, after the first fluid bladder 202 is squeezed 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, The second fluid bladder 203 may protrude from the edges of the first body 101 and the second body 102 . When the second fluid bag 203 protrudes from the edges of the first body 101 and the second body 102, it does not occupy the space of the electronic device and does not squeeze the components in the electronic device, which can reduce the design process of the electronic device. It can protect the normal operation of the devices in the electronic equipment, and effectively prevent the devices in the electronic equipment from being damaged due to extrusion. When the flexible screen 3 is in a bent state, the pressure of the fluid in the first fluid bag 202 increases due to the reduction of the space of the first fluid bag 202, which can also make the first fluid bag 202 affect the The bent portion 301 plays a good supporting role, effectively preventing the bent portion 301 from being curled and arched due to being in a bent state.

Specifically, the first body 101 and the second body 102 may be integrally formed with a flexible material to form the device body 1, or may be of a separate design and both are connected with the flexible screen 3, or the first body 1 A main body 101 and the second main body 102 are connected by a flexible material, which is not limited in the present invention.

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

Specifically, the fluid can be a gas, such as inert gas helium, neon, argon, etc. Since the gas has greater compressibility, in order to ensure that the fluid in the fluid bladder 2 can always keep the correct The bending part 301 of the flexible screen 3 is sufficiently supported, and the pressure range of the fluid can be 0.12-0.5MPa, preferably 0.15-0.4MPa; in addition, the fluid can be a liquid, such as water, and ethyl acetate with a higher ignition point. For safe and cheap liquids such as glycol and glycerol, due to the small compressibility of the liquid, the pressure range of the fluid can be 0.10-0.2MPa, preferably 0.12-0.18MPa, so as to ensure the fluid bladder 2 While the bent portion 301 of the flexible screen 3 of the fluid pair inside is sufficiently supported, the service life of the fluid bladder 2 can be extended under a low pressure state.

Optionally, the folding angle of the bending portion 301 ranges from 0° to 180°, and the folding angle is specifically the angle between the first body 101 and the second body 102 . The user can open the electronic device to a specified angle according to the needs, which is convenient for the user to operate.

The folding range of the bending portion 301 directly affects the user's experience of using the foldable electronic device. However, the fluid bladder 2 of the present invention can always maintain sufficient support for the bent portion 301 of the flexible screen 3 when the flexible screen 3 is in a bent state or even in an unfolded state, so that the folding angle of the bent portion 301 It can be bent from 180° in the unfolded state to 0° in the maximum bending state, which improves the user experience and reduces the area occupied by the electronic device.

Optionally, referring to FIG. 1 , the first body 101 and the second body 102 are arranged symmetrically with respect to the first gap 103 , that is, the first body 101 and the second body 102 are the same. When the flexible screen 3 of the electronic device is in a bent state, the first body 101 and the second body 102 are completely overlapped, which effectively reduces the volume of the electronic device and also has higher practicability.

In addition, when 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 improve the appearance consistency of the electronic device.

Specifically, the symmetry plane of the bending portion 301 is the A-A plane in FIG. 1 , that is, the bending symmetry plane when the bending portion 301 is bent. Since the fluid bladder 2 is filled with the first gap 103. During the bending process of the bending portion 301, the symmetrically arranged first body 101 and the second body 102 can perform symmetrical extrusion deformation on the fluid bladder 2, and then the fluid bladder 2 The bending portion 301 can be supported symmetrically and comprehensively, the stress of the entire bending portion 301 can be reduced, and damage to the flexible screen 3 caused by stress concentration can be avoided.

Optionally, when the flexible screen 3 is in the unfolded state, the volume of the first fluid bag 202 is greater than the volume of the second fluid bag 203, that is, the fluid is mainly concentrated in the first fluid bag 202, The first fluid bladder 202 is enabled to support the flexible screen. When the flexible screen 3 is in a bent state, the volume of the first fluid bag 202 is smaller than the volume of the second fluid bag 203 . Due to the bending of the flexible screen 3 and the compression of the first fluid bladder 202 , the fluid in the first fluid bladder 202 flows to the second fluid bladder 203 . Therefore, the volume of the first fluid bladder 202 is smaller than that of the second fluid bladder 203 volume of.

Specifically, when the flexible screen 3 is in the unfolded state, the cross-sectional shape of the first gap 103 may be similar to a wedge shape, and the area close to the flexible screen 3 is larger than the area away from the flexible screen 3. , so that the larger part of the upper end of the fluid bladder 2 supports the bent portion 301 during the extrusion deformation process. At this time, the volume of the first fluid bladder 202 is larger than that of the second fluid bladder 203 volume. When the flexible screen 3 is in a bent state, due to the extrusion of the flexible screen 3, the cross-sectional shape of the first gap 103 may be similar to a trapezoid, and the area close to the flexible screen 3 is smaller than that far away from the flexible screen 3. The shape of the area characteristic of the flexible screen 3, after the first fluid bag 202 is squeezed by the first body 101 and the second body 102, the fluid in the first fluid bag 202 flows to the first fluid bag 202. Two fluid bladders 203 , at this time, the volume of the first fluid bladder 202 is smaller than the volume of the second fluid bladder 203 .

In the case that a large amount of fluid flows into the first fluid bag 202 or the second fluid bag 203 , the fluid bag has better accommodation, which can effectively prevent the electronic device from breaking in the unfolded or bent state. Therefore, when the flexible screen 3 is switched between the bending state and the unfolding state, the fluid filled in the fluid bag 2 can flow from the first fluid bag 202 to the second fluid bag only by the external force of the bending process itself. The second fluid bladder 203 realizes the directional flow of the fluid filled in the fluid bladder 2 while maintaining the stable support of the flexible screen 3 by the fluid bladder 2 , and ensures the long-term stability of the support of the fluid bladder 2 .

The mutual attraction between the magnetic member 4 and the soft magnetic layer 5 can be used to adjust the pressure distribution and effect size of the fluid in the fluid capsule 2 .

Specifically, when the flexible screen 3 is in the unfolded state, the fluid in the fluid bag 2 can support the bending portion 301 of the flexible screen 3 well, supporting the bending portion. The bottom area of 301, combined with the electromagnetic force of the magnetic member 4 and the soft magnetic layer 5 attracting each other, can strengthen the support effect of the fluid in the fluid bag 2 on the bending part 301; similarly, the flexible screen 3 In the case of being in a bent state, when the flexible screen 3 is in any specific bending position, it can be subjected to the hydraulic pressure of the fluid in the fluid bladder 2 and the magnetic member 4 and the soft magnetic layer 5 . The resultant force of the mutually attractive electromagnetic forces eliminates part of the stress of the bending portion 301 of the flexible screen 3 during the bending process, so that the bending portion 301 is effectively and uniformly supported.

Specifically, the symmetrically arranged first magnetic member 41 and the second magnetic member 42 can both interact with the soft magnetic layer 5 to generate a symmetrical magnetic attraction force, thereby producing a symmetrical squeeze on the fluid capsule 2 . Since the internal stress generated by the bending part 301 during the bending process is also symmetrical, the extrusion effect caused by the symmetrical electromagnetic suction can act on the bending part 301, and the bending part 301 The symmetrical support can just reduce the symmetrical internal stress of the bending part 301 and improve the bending life of the bending part 301 .

In addition, when the first body 101 and the second body 102 squeeze the fluid bladder 2 , the size of the side of the first gap 103 away from the flexible screen 3 will increase, while the size of the telescopic portion will increase. The setting can just satisfy the change of the structure of the first gap 103 .

Optionally, referring to FIGS. 1 and 2 , the electronic device further includes an adhesive layer 6 , and the fluid capsule 2 is connected to the flexible screen 3 through the adhesive layer 6 .
