Description

Electronic device

Technical Field

The present application relates to the field of electronic technology, and more particularly, to an electronic device.

Background

With the development of electronic device technology, users have a higher demand for electronic devices having a large size and easy to carry, and therefore electronic devices having a curved display screen are receiving wide attention. When the bending type display screen is assembled with a shell of an electronic device, in order to ensure that the bending and unfolding states can be switched, a bending deformation area of the display screen is not fixedly connected with the shell. When the bending type display screen is bent, the bending deformation area can have two possible motion states of outward convex bending and inward concave bending. For an inwardly curved display screen (i.e., two display surfaces of the display screen can be relatively curved and contained between the curved housings), the outwardly convex bending motion state will prevent the display screen from being normally inwardly curved, and even damage the display screen.

The electronic equipment comprises a shell and a flexible screen, wherein the flexible screen comprises a first fixed area, a bending area and a second fixed area, the bending area is connected between the first fixed area and the second fixed area, the shell comprises a first part and a second part which can be bent or unfolded relatively, the first fixed area is arranged on the first part, the second fixed area is arranged on the second part, one side of the bending area, which is close to the shell, is provided with at least two convex blocks, and the at least two convex blocks are arranged in the direction from the first part to the second part;

the at least two tabs abut each other when the first portion is deployed relative to the second portion; when the first part is bent relative to the second part, the bending area is positioned on the inner side of the shell, and the at least two lugs are separated from each other.

In this embodiment, the at least two bumps are disposed on the surface of the bending region close to the housing, and the at least two bumps are abutted to each other when the electronic device is in the flat state, so that when the electronic device changes from the flat state to the bent state, the bending region cannot be arched in a direction away from the housing under the abutting force between the at least two bumps, that is, the flexible screen is ensured to be bent in a direction close to the inner side of the housing, and the electronic device has a better bending effect.

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.

In order that the above objects, features and advantages of the present application can be more clearly understood, a detailed description of the present application will be given below with reference to the accompanying drawings and detailed description. In addition, the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth to provide a thorough understanding of the present application, and the described embodiments are merely a subset of the embodiments of the present application, rather than all embodiments. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application.

Referring to fig. 1, an electronic device 100 is provided in an embodiment of the present disclosure. The electronic device 100 may achieve a flattening and bending effect. The electronic device 100 may be a tablet computer, a mobile phone, a camera, a personal computer, a notebook computer, a vehicle-mounted device, a wearable device, or other intelligent devices. For convenience of description, the electronic device 100 is defined with reference to the first viewing angle, the width direction of the electronic device 100 is defined as the X direction, the length direction of the electronic device 100 is defined as the Y direction, and the thickness direction of the electronic device 100 is defined as the Z direction.

As shown in fig. 1 to 3, the electronic device 100 includes a housing 2 and a flexible screen 40. It will be appreciated that the flexible screen 40 is an area that displays an electronic image. The flexible screen 40 may be an organic electroluminescent flexible screen or a liquid crystal flexible screen. In addition, the housing 2 may include, but is not limited to, the first, second and third divided

housings

10, 20 and 30 shown in fig. 2 and 3. The housing 2 may also comprise an integral flexible casing. The flexible screen 40 includes a first fixing area 41, a bending area 42, and a second fixing area 43. The bending zone 42 is connected between the first fixation zone 41 and the second fixation zone 43. The housing 2 comprises a first part 1 and a second part 3 which can be bent or unfolded relative to each other. The first fastening area 41 is attached to the first part 1 and the second fastening area 42 is attached to the second part 3. Alternatively, the first fastening region 41 may be attached to the first fastening region 41 by glue or fasteners. The second fastening section 42 may also be attached to the second part 3 by means of glue or fasteners.

Furthermore, as shown in fig. 1 and fig. 2, at least two bumps 421 are disposed on a side of the bending region 42 close to the housing 2, and the at least two bumps 421 are arranged in a direction from the first portion 1 to the second portion 3, that is, the at least two bumps 421 are arranged along the Y-axis direction. Only two bumps 421 are shown in fig. 1 to 3, but the number of bumps 421 may be multiple in other embodiments.

As shown in fig. 4 and 5, when the first portion 1 is unfolded relative to the second portion 3, that is, the electronic device 100 is in a flat state, at least two of the bumps 421 abut against each other. It can be understood that, in the process design and production process, due to the limitation of error or process level, the at least two bumps 421 of the present application may not be completely abutted, but the at least two bumps 421 are disposed as close as possible, that is, there may be a gap between the at least two bumps 421, at this time, the gap between the at least two bumps 421 should be acceptable to those skilled in the art, and the gap should not affect the achievement of the objectives of the embodiments of the present application.

Of course, in other embodiments, a small gap is reserved between two adjacent bumps 421, and the small gap can absorb the tolerance of the gap existing between two bumps 421 during the process design and production. In addition, a small gap is reserved between two adjacent bumps 421, so that when the first portion 1 is bent relative to the second portion 3, that is, when the electronic device 100 changes from the flat state to the bent state, a buffer space is provided between the two bumps 421, that is, at the moment when the bending region 42 is arched away from the third casing 30, the two bumps are prevented from being suddenly pressed against each other.

Furthermore, as shown in fig. 2, when the first portion 1 is bent relative to the second portion 3, that is, when the electronic device 100 is in a bent state, the bending region 42 is located inside the housing 2, and the at least two bumps 421 are separated from each other. It is understood that the bending region 42 is bent when the electronic device 100 is in a bent state, and at this time, the bending region 42 is partially located inside the housing 2. In addition, since the bending region 42 is bent, at least two protrusions 421 provided on the bending region 42 are no longer abutted against each other, or the distance between at least two protrusions 421 becomes large.

In this embodiment, the at least two bumps 421 are disposed on the surface of the bending region 42 close to the housing 2, and the at least two bumps 421 are abutted to each other when the electronic device 100 is in the flattened state, so that when the electronic device 100 changes from the flattened state to the bent state, the bending region 42 cannot be arched in a direction away from the housing 2 under the abutting force between the at least two bumps 421, that is, the flexible screen 40 is ensured to be bent in a direction close to the inner side of the housing 2, and thus the electronic device 100 has a better bending effect.

In one embodiment, as shown in fig. 1 and 2, the housing 2 further comprises a third portion 5. The third portion 5 is connected to the first portion 1 and the second portion 3. It will be appreciated that the third portion 5 may comprise the third housing 30 of figures 2 and 3. The third portion 5 may also be a middle region of a flexible housing. The third portion 5 forms a receiving space 311. When the first portion 1 is bent relative to the second portion 3, at least a portion of the bending region 42 is received in the receiving space 311. Referring to fig. 5, when the first portion 1 is flattened relative to the second portion 3, at least a portion of the bending region 42 is opposite to the accommodating space 311. It is understood that at least a portion of the bending region 42 facing the accommodating space 311 means: when the electronic apparatus 100 is in the flat state, the bending region 42 is planar, and the bending region 42 is located outside the accommodating space 311. At this time, the orthogonal projection of the accommodating space 311 on the flexible screen 40 is located within the bending region 42.

Further, as shown in fig. 2 and 3, the first part 1 includes a first housing 10. The second part 3 comprises a second housing 20. The third part 5 comprises a third housing 30. The third housing 30 includes a first side 31 and a second side 32 disposed opposite to each other. The first side 31 and the second side 32 form a receiving space 311 therebetween. It will be appreciated that the third housing 30 further includes a bottom wall 33 connected to the first side 31 and the second side 32. The third housing 30 is substantially U-shaped. The first side 31 of the third housing 30 extends in a direction perpendicular to the direction from the first side 31 towards the second side 32, i.e. the direction of extension of the first side 31 is parallel to the X-axis. The second side 32 of the third housing 30 extends in a direction perpendicular to the direction from the first side 31 towards the second side 32, i.e. the second side 32 extends in a direction parallel to the X-axis. The bottom wall 33 of the third housing 30 forms the bottom wall 33 of the housing space 311. The first housing 10 is pivotally connected to the first side 31. The second housing 20 is pivotally connected to the second side 32. It will be appreciated that the first housing 10 rotates in the Y-Z plane relative to the first side 31. The second housing 20 rotates in the Y-Z plane relative to the second side 32.

Wherein the first fixing section 41 is mounted to the first housing 10 as shown in fig. 4. The second fixing section 43 is mounted to the second housing 20. Alternatively, the first fixing area 41 and the first housing 10 may be sealed by a sealing foam, and the second fixing area 43 and the second housing 20 may be sealed by a sealing foam, so as to prevent external liquid or dust from entering the inside of the electronic device 100.

It is understood that, referring again to fig. 2, when the electronic device 100 is in a bent state, the first fixing area 41 and the second fixing area 43 of the flexible screen 40 are vertically and oppositely disposed. Referring to fig. 4 and fig. 5 again, when the electronic device 100 is in the flattened state, a plane formed by the first fixing region 41, the bending region 42 and the second fixing region 43 of the flexible screen 40 is between 150 ° and 180 °. Fig. 4 shows an example of 180. When the electronic device 100 is bent from the flat state to the bent state, the first housing 10 and the second housing 20 both rotate relative to the third housing 30, and at this time, the bending region 42 located outside the accommodating space 311 is bent toward the bottom wall 33 close to the accommodating space 311.

In this embodiment, the first housing 10 and the second housing 20 are arranged to rotate relative to the third housing 30, so that the flexible screen 40 is bent, and the first fixing area 41 and the second fixing area 43 are arranged to face each other, so as to reduce the area of the front side of the electronic device 100, that is, the area of the electronic device 100 on the X-Y plane, thereby facilitating carrying and use by a user.

In one embodiment, as shown in FIGS. 3 and 5, bending region 42 has a bend line 422. Bending region 42 bends centered on bend line 422. It is understood that the bending line 422 of the present application is not a true line on the bending region 42, but a straight line defined to clearly express the position of the bump 421. Bend line 422 of bend region 42 is linear. Bend line 422 is depicted in dashed lines in FIG. 3. Bending zone 42 includes a left side 423 on one side of bend line 422 and a right side 424 on the other side of bend line 422. The left side portion 423 connects the right side portion 424. The left side portion 423 and the right side portion 424 are both provided with at least one protrusion 421, that is, the left side portion 423 is provided with at least one protrusion 421, and the right side portion 424 is provided with at least one protrusion 421. The left side 423 and the right side 424 of fig. 3 each have a protrusion 421.

Further, as shown in fig. 2 and 5, the at least two bumps 421 include a first bump 425 and a second bump 426. The first protrusion 425 is provided on the left side portion 423. A second tab 426 is provided on the right side 424. The first bump 425 comprises a first abutment face 427 facing the second bump 426. The second projection 426 comprises a second abutment surface 428 facing the first projection 425. As shown in fig. 5, when the electronic device 100 is in the flat state, the first abutting surface 427 abuts against the second abutting surface 428. In fig. 5, since the first abutting surface 427 and the second abutting surface 428 abut, the numbers of the first abutting surface 427 and the second abutting surface 428 are marked on the same straight line. It is understood that when the electronic device 100 is in the flat state, the first abutting surface 427 may abut against the second abutting surface 428 partially or may abut against the second abutting surface 428 completely.

Further, as shown in fig. 2, when the electronic apparatus 100 is in the bent state, the first abutment surface 427 and the second abutment surface 428 are separated from each other. In another embodiment, the first contact surface 427 and the second contact surface 428 may be partially separated and partially attached to each other. When the electronic apparatus 100 changes from the flat state to the bent state, the first abutting surface 427 and the second abutting surface 428 abut against each other, so that at a moment when the bending region 42 is arched in a direction away from the third housing 30, the first abutting surface 427 presses the second abutting surface 428, and the second abutting surface 428 blocks the first abutting surface 427 from approaching the second bump 426, thereby preventing the bending region 42 from continuously arched in a direction away from the third housing 30.

In this embodiment, the first abutting surface 427 and the second abutting surface 428 have a plurality of setting manners:

in the first embodiment, as shown in fig. 5, when the electronic device 100 is in the flat state, the orthographic projection of the first abutting surface 427 and the second abutting surface 428 on the flexible screen 40 coincides with the bending line 422, that is, the first abutting surface 427 and the second abutting surface 428 overlap the bending line 422 on the X-Y plane. It is understood that when the electronic device 100 changes from the flat state to the curved state, if the curved region 42 has a tendency to bow away from the third housing 30, the curved region 42 at the bend line 422 will bow away from the third housing 30 first. At this time, the bending region 42 at the bending line 422 will drive the first abutting surface 427 to press the second abutting surface 428, so that the bending region 42 is further arched away from the third housing 30. However, since the first abutting surface 427 and the second abutting surface 428 abut against each other, the second abutting surface 428 can effectively block the pressing of the first abutting surface 427, so that the bending region 42 at the bending line 422 is not bent. Therefore, when the electronic device 100 is in the flat state, the orthographic projection of the first abutting surface 427 and the second abutting surface 428 on the flexible screen 40 coincides with the bending line 422, so that the bending area 42 at the bending line 422 tends to be arched in a direction away from the third housing 30, and the bending area 42 is prevented from being arched in a direction away from the third housing 30.

In the second embodiment, most of the same technical contents as those in the first embodiment are not described again: as shown in fig. 6. Fig. 6 is a schematic structural view of an embodiment of the flexible screen 40. The first bump 425 includes a first body portion 4251 and a first extension portion 4252 connected to each other. The first abutting surface 427 is partially located on the first body portion 4251 and partially located on the first extension portion 4252, that is, the first abutting surface 427 includes a first portion 4271 and a second portion 4272 connected to each other. The first portion 4271 is located in the first body portion 4251 and the second portion 4272 is located in the first extension 4252. Optionally, the second portion 4272 is a curved surface or a flat surface. For example, as shown in fig. 6, when second portion 4272 is arcuate, second portion 4272 is directly connected to first portion 4271. When second portion 4272 is planar, second portion 4272 may be connected to first portion 4271 by an arc or a plane. It will be appreciated that when the first protrusion 425 has the first extension 4252, the second abutment surface 428 is partially located in a groove wall of the first recess 4263 by providing the first recess 4263 on the second protrusion 426. At this time, when the electronic device 100 is in a flattened state, the second portion 4272 may be fitted on a groove wall of the first concave portion 4263.

Specifically, FIG. 7 is a cross-sectional diagram of one embodiment of the electronic device 100 in a flattened state. Fig. 8 is a schematic structural diagram of an embodiment of the electronic device 100 in a bent state. As shown in fig. 7, the first body portion 4251 is fixed to the left portion 423. Optionally, the first body portion 4251 is adhered to the left side portion 423 by an adhesive. The first extension portion 4252 abuts against the right side portion 424 when the electronic device 100 is in the flat state. As shown in fig. 8, the first extension portion 4252 can be disengaged from the right side portion 424 when the electronic device 100 is in a bent state, i.e., the first extension portion 4252 is separated from the flexible screen 40. It can be understood that when the electronic device 100 changes from the flat state to the bent state, the bending region 42 has a tendency to bow away from the third housing 30, and at this time, since the first extension portion 4252 partially fits the bending region 42 at the bending line 422, the bending region 42 at the bending line 422 is blocked by the first extension portion 4252 at a moment when bending occurs, so as to prevent the bending region 42 from bowing away from the third housing 30. In addition, the second portion 4272 abuts against the second abutting surface 428 of the right portion 424, that is, the second portion 4272 abuts against a groove wall of the first concave portion 4263, so that the right portion 424 is prevented from being arched away from the third housing 30.

In the third embodiment, most of the same technical contents of the second embodiment are not described again:

as shown in fig. 9, the first body portion 4251 is provided with a second concave portion 4253. The first abutment surface 427 is partially located on a groove wall of the second concave portion 4253, and the other part is located on the first extension 4252, that is, the first part 4271 is located on a groove wall of the second concave portion 4253, and the second part 4272 is located on the first extension 4252. Specifically, the second protrusion 426 includes a second body portion 4261 and a second extension portion 4262 connected to each other. The second abutting surface 428 is partially located on the second body portion 4261, and the other part is located on the second extension portion 4262. It will be appreciated that the second abutment surface 428 includes a third portion 4281 and a fourth portion 4282 connected to each other. The third portion 4281 is located at the second body portion 4261. The fourth portion 4282 is located in the second extension 4262. The fourth portion 4282 may be a curved surface or a flat surface. When the fourth portion 4282 is arcuate, as shown in fig. 9, the fourth portion 4282 is directly connected to the third portion 4281. When the fourth portion 4282 is planar, the fourth portion 4282 may be connected to the third portion 4281 by an arc or a plane. When the electronic device 100 is in a flattened state, the third portion 4281 is attached to the first portion 4271. Fourth portion 4282 is attached to second portion 4272.

Specifically, the second body portion 4261 is fixedly connected to the right portion 424. Optionally, the second body portion 4261 is adhered to the right side portion 424 by an adhesive. The second extension portion 4262 abuts against the left side portion 423 when the electronic device 100 is in the flat state. The second extension 4262 is disengaged from the left side portion 423 when the electronic device 100 is in the bent state, i.e., the second extension 4262 is separated from the flexible screen 40. It can be understood that when the electronic device 100 changes from the flat state to the bent state, the bending region 42 has a tendency to bow away from the third casing 30, and at this time, since the second extension portion 4262 partially fits the bending region 42 at the bending line 422, the bending region 42 at the bending line 422 is blocked by the second extension portion 4262 at a moment when bending occurs, so as to prevent the bending region 42 from bowing away from the third casing 30. In addition, the fourth portion 4282 is attached to the first abutment surface 427 of the left portion 423, that is, the fourth portion 4282 is attached to the first portion 4271, so that the left portion 423 is prevented from being arched away from the third housing 30.

In another embodiment, as shown in fig. 10, the second recessed portion 4253 is spaced apart from the first extension portion 4252, i.e., a portion of the first abutment surface 427 is located between the second recessed portion 4253 and the first extension portion 4252. Fig. 10 shows that the first portion 427 between the second valley 4253 and the first extension 4252 overlaps the bend line 422 in the orthographic projection of the display screen 20. Of course, in the present embodiment, the first concave portion 4263 and the second extending portion 4262 are arranged at an interval so that a part of the second contact surface 428 is located between the first concave portion 4263 and the second extending portion 4262, so that the first contact surface 427 can be attached to the second contact surface 428 when the electronic apparatus 100 is in the flat state.

In another embodiment, as shown in fig. 11, the at least two bumps 421 include a first bump 425, a second bump 426, and a third bump 427. The first protrusion 425 is provided on the left side portion 423. A second tab 426 is provided on the right side 424. The third bump 427 is located between the first bump 425 and the second bump 426. The first bump 425 comprises a first abutment surface 4251 facing the third bump 427. The second bump 426 comprises a second abutment surface 4261 facing the third bump 427. The third bump 427 includes a third abutting surface 4271 and a fourth abutting surface 4272 which are opposite to each other. The third abutting surface 4271 is disposed toward the first bump 425. When the electronic apparatus 100 is in a flattened state, the first contact surface 4251 is in contact with the third contact surface 4271, and the second contact surface 4261 is in contact with the fourth contact surface 4272. Optionally, the orthographic projection of the third bump 427 on the display screen 20 covers the bending line 422.

It can be understood that when the electronic device 100 changes from the flat state to the bent state, if the bending region 42 has a tendency to bow in a direction away from the third housing 30, the first bump 425 will press against the third bump 427, the second bump 426 will press against the third bump 427, that is, the first abutment surface 4251 presses against the third abutment surface 4271, and the fourth abutment surface 4272 presses against the second abutment surface 4261. However, since the first abutment surface 4251 abuts against the third abutment surface 4271 and the second abutment surface 4261 abuts against the fourth abutment surface 4272, the third abutment surface 4271 can effectively block the pressing of the first abutment surface 4251, and the second abutment surface 4261 can effectively block the pressing of the fourth abutment surface 4272, so that the bending region 42 is not arched in a direction away from the third housing 30.

Further, an orthographic projection of the third abutting surface 4271 on the flexible screen 40 is symmetrical to an orthographic projection of the fourth abutting surface 4272 on the flexible screen 40 about the bending line 422. At this time, the third protrusion applies uniform pressure to the left side portion 423 and the right side portion 424 of the flexible screen, that is, the flexible screen is guaranteed to be bent uniformly in the bending process.

Further, the third abutment surface 4271 may be provided in the manner of the first abutment surface 427 according to the second embodiment. At this time, the shape of the first abutment surface 4251 of the present embodiment is adapted to the third abutment surface 4271. The fourth abutment surface 4261 may be provided in the manner of providing the first abutment surface 427 according to the second embodiment. At this time, the second abutment surface 4261 of the present embodiment is fitted to the fourth abutment surface 4261.

In one embodiment, as shown in FIG. 12, the flexible screen 40 includes a flexible substrate 44. The flexible substrate 44 includes a first side 441 and a second side 442 opposite each other. First face 441 is secured to flex region 42. At least two bumps 421 are fixed on the second surface 442. It will be appreciated that the material of the flexible substrate 44 may be consistent with the substrate material of the flexible screen 40. The first side 441 may be adhered to the flexure zone 42 by an adhesive. The at least two protrusions 421 can also be secured to the second face 442 by an adhesive. It can be understood that, by providing the flexible substrate 44 in the flexible screen 40, the at least two bumps 421 can be firstly fixed to the second surface 442, and then the flexible substrate 44 and the at least two bumps 421 are fixed to the bending area 42 as a whole, so as to improve the positioning accuracy of the at least two bumps 421 on the bending area 42. In other embodiments, the material of the flexible substrate 44 may also be Thermoplastic polyurethane elastomer rubber (TPU), common silicone rubber, magic rubber, AB rubber, or rubber, and the embodiment is not limited.

In one embodiment, the hardness of the bump 421 is greater than the hardness of the flexible screen 40. It is understood that when the electronic apparatus 100 changes from the flat state to the bent state, the first abutting surface 427 presses the second abutting surface 428 at a moment when the bending section 42 is arched away from the third housing 30. At this time, by providing the hardness of the projection 421 to be greater than that of the flexible panel 40, the ability of the second abutment surface 428 to block the first abutment surface 427 can be improved, thereby further avoiding the arching of the bending section 42 in a direction away from the third housing 30.

Optionally, the material of the bump 421 is metal or hard plastic. Such as stainless steel, iron alloy or Polyethylene terephthalate (PET).

In another embodiment, as shown in fig. 13, the bump 421 includes a flexible portion 4215 and a rigid portion 4216 connected to each other. The flexible portion 4215 is connected between the bending region 42 and the rigid portion 4216. Optionally, the flexible portion 4215 is made of the same material as the substrate of the flexible screen 40. The rigid portion 4216 may be made of, but not limited to, metal or rigid plastic. The flexible portion 4215 may be adhered to the flexible screen 40 by an adhesive. In the present embodiment, the bumps 421 are arranged as the flexible portions 4215 and the rigid portions 4216 connected to each other, on one hand, the flexible portions 4215 are connected to the flexible screen 40 to prevent the rigid portions 4216 from being directly connected to the flexible screen 40 to scratch the flexible screen 40 or affect signal transmission of the flexible screen 40, and on the other hand, in the flat state of the electronic device 100, the rigid portions 4216 of at least two bumps 421 abut against each other to ensure that the two bumps 421 are not deformed when pressed against each other, so as to further prevent the flexible screen 40 from being arched away from the third housing 30 when the electronic device 100 is bent from the flat state to the bent state. In other embodiments, the flexible portion 4215 may be made of Thermoplastic polyurethane elastomer rubber (TPU), common silicone rubber, magic rubber, AB rubber, or rubber, and the application is not limited in particular.

In one embodiment, the thickness of the bump 421 in the first direction is greater than twice the thickness of the flexible screen 40 in the first direction. The first direction is a direction perpendicular to the display surface of the flexible screen 40, i.e., a negative direction of the Z-axis. It is understood that when the electronic apparatus 100 changes from the flat state to the bent state, the first abutting surface 427 presses the second abutting surface 428 at a moment when the bending section 42 is arched away from the third housing 30. At this time, by providing the thickness of the projection 421 to be greater than twice the thickness of the flexible panel 40, the ability of the second abutment surface 428 to block the first abutment surface 427 can be improved, thereby further ensuring that the bending section 42 does not arch in a direction away from the third housing 30.

In this embodiment, the bump 421 has a plurality of setting manners:

the first implementation mode comprises the following steps: referring to fig. 14, fig. 14 is a schematic structural diagram of an embodiment of the flexible screen 40 in a flattened state. The number of the protrusions 421 provided on the left portion 423 and the right portion 424 is one, that is, the protrusion 421 provided on the left portion 423 is the first protrusion 425, and the protrusion 421 provided on the right portion 424 is the second protrusion 426. The first bump 425 and the second bump 426 are both in the shape of a bar. The extending direction of the bump 421 is perpendicular to the second direction. The second direction is the direction of the first portion 1 towards the second portion 3, i.e. the extension direction of the bump 421 is parallel to the X-axis. It will be appreciated that the projection 421 of the left side portion 423 extends from one end of the flexible screen 40 to the other end, i.e. the first abutment surface 427 of the projection 421 is a continuous plane. The bump 421 of the right side portion 424 extends from one end to the other end of the flexible screen 40, and the second abutting surface 428 of the bump 421 is a continuous plane.

In the second embodiment, the difference from the first embodiment is: referring to fig. 15, fig. 15 is a schematic structural diagram of an embodiment of the flexible screen 40 in a flattened state. The number of the protrusions 421 provided on the left side 423 and the right side 424 is plural. The plurality of bumps 421 are distributed in an array, and a row direction or a column direction of the array is perpendicular to the second direction. The second direction is the direction in which the first portion 1 is directed towards the second portion 3. It is understood that the at least plurality of protrusions 421 includes a plurality of first protrusions 425 disposed on the left side portion 423 and a plurality of second protrusions 426 disposed on the right side portion 424. The first bumps 425 are arranged in an array. The second bumps 426 are arranged in an array. Fig. 13 shows a plurality of first protrusions 425 arranged in a row along the X-axis. The second bumps 426 are arranged in a row along the X-axis. Of course, in other embodiments, the bumps 421 on the left portion 423 may be arranged in an n × n manner. The bumps 421 on the right side portion 424 may also be arranged in an n × n manner. At this time, when the plurality of first bumps 425 are arranged in an array, the first abutting surface 427 is a discontinuous plane. When the plurality of second bumps 426 are arranged in an array, the second abutting surface 428 is a discontinuous plane.

In the present embodiment, referring to fig. 2, fig. 4 and fig. 5 again, the third portion 5 includes a movable plate 50. The movable plate 50 is slidably mounted on the third housing 30, and the movable plate 50 is located in the accommodating space 311. The movable plate 50 is adjacent to the bending region 42 when the first portion 1 is flattened relative to the second portion 3, i.e. the electronic device 100 is in a flattened state. The movable plate 50 is close to the bottom wall 33 of the accommodating space 311 when the first portion 1 is bent relative to the second portion 3, i.e. the electronic device 100 is in a bent state. Specifically, when the electronic device 100 is unfolded from the bending state to the unfolding state, the movable plate 50 moves to a direction close to the flexible screen 40. When the electronic device 100 is in the flattened state, the surface of the movable plate 50 close to the flexible screen 40 abuts against the at least two bumps 421 on the bending region 42. At this time, the movable plate 50 abuts against the at least two bumps 421, and the at least two bumps 421 support the flexible screen 40, so that it is ensured that the flexible screen 40 is not recessed when the flexible screen 40 is touched by a user.

Further, as shown in fig. 16, the surface of the movable plate 50 facing the flexible screen 40 is provided with a groove 51. The groove 51 is recessed in the direction of the inside of the movable plate 50. When the first portion 1 is flattened relative to the second portion 3, that is, the electronic device 100 is in a flattened state, the at least two bumps 421 are received in the grooves 51, and the surface of the movable plate 50 facing the flexible screen 40 abuts against the bending region 42. It will be appreciated that the number of grooves 51 may be one. When the electronic device 100 is in the flattened state, the groove 51 can accommodate all the bumps 421 on the flexible screen 40 in the groove 51. In other embodiments, the number of the grooves 51 may be multiple, and the grooves 51 correspond to the bumps 421 one by one. Each recess 51 receives one of the bumps 421 when the electronic device 100 is in the flattened state. Therefore, by providing the groove 51 on the movable plate 50, when the electronic device 100 is in the flat state, the bump 421 disposed in the bending region 42 is received in the groove 51, and the surface of the movable plate 50 close to the flexible panel 40 is attached to the bending region 42. At this time, the flexible screen 40 is supported by the movable plate 50 so that the flexible screen 40 is not depressed when the flexible screen 40 is touched by a user.

Further, when the electronic device 100 is in the flat state, the bump 421 abuts against the bottom wall 511 of the groove 51. Specifically, when the electronic device 100 is in the flattened state, the surface of the bump 421 facing the movable plate 50 is attached to the bottom wall 511 of the groove 51. At this time, the movable plate 50 abuts against the at least two bumps 421, and the at least two bumps 421 support the flexible screen 40, so that it is ensured that the flexible screen 40 is not recessed when the flexible screen 40 is touched by a user.

As shown in fig. 17, the first part 1 includes a first rotation arm 61. The second part 3 comprises a second turning arm 62. The first rotation arm 61 is fixed to the first housing 10. The second rotating arm 62 is fixed to the second housing 20. In one embodiment, the first rotation arm 61 is fixed to the first housing 10 by a fastener. The second rotating arm 62 is also fixed to the second housing 20 by a fastener. The first rotation arm 61 is provided with a first through hole 611. The first through holes 611 are bar-shaped through holes. The second rotating arm 62 is provided with a second through hole 621. The second via 621 is also a stripe via. Referring to fig. 17 and 18, the movable plate 50 has a first projection 631 and a second projection 632 spaced apart from each other at an end thereof. The shape of the first bump 631 is adapted to the shape of the first through hole 611. The shape of the second protrusion 632 is matched with the shape of the second through hole 621. The first projection 631 is slidably connected to the first through hole 611. The second protrusion 632 is slidably connected to the second through hole 621.

When the first housing 10 rotates relative to the third housing 30, that is, the first housing 10 rotates relative to the third housing 30 on the Y-Z plane, the first housing 10 drives the first rotating arm 61 to rotate relative to the third housing 30, that is, the first rotating arm 61 also rotates relative to the third housing 30 on the Y-Z plane, and at this time, the hole wall of the first through hole 611 presses the first protrusion 631 so that the first protrusion 631 moves from one end of the first through hole 611 to the other end. Similarly, the second protrusion 632 is pressed by the wall of the second through hole 621, so that the second protrusion 632 moves from one end of the second through hole 621 to the other end. At this time, the movable plate 50 moves in the Z direction in the accommodation space 311. Therefore, the first projection 631 slides in the first through hole 611, and the second projection 632 slides in the second through hole 621, so that the movable plate 50 is close to the flexible screen 40 when the electronic device 100 is in the flat state, and the movable plate 50 is close to the bottom wall 33 of the accommodating space 311 when the electronic device 100 is in the bent state.

Further, as shown in fig. 17 and 19, the third portion 5 includes a fixing plate 34. The fixing plate 34 is fixed to the ends of the first side 31 and the second side 32. It will be appreciated that the fixing plate 34 is located between the first side 31 and the second side 32. The fixing plate 34 is provided with a first sliding hole 341 and a second sliding hole 342 which are arranged at an interval. The extending directions of the first sliding hole 341 and the second sliding hole 342 are parallel to the Z direction. The first projection 631 is slidably mounted to the first through hole 611 through the first sliding hole 341. The second protrusion 632 is slidably mounted in the second through hole 621 through the second sliding hole 342. It can be understood that when the electronic device 100 is in the flat state, the first projection 631 is located at the end of the first sliding hole 341 away from the bottom wall 33 of the third casing 30, and the second projection 632 is located at the end of the second sliding hole 342 away from the bottom wall 33 of the third casing 30, and at this time, the movable plate 50 supports the flexible screen 40. Referring to fig. 19, when the electronic device 100 is in the bent state, the first projection 631 is located at an end of the first sliding hole 341 close to the bottom wall 33, and the second projection 632 is located at an end of the second sliding hole 342 close to the bottom wall 33, at this time, the movable plate 50 is received in the receiving space 311. During bending or flattening of the flexible screen 40, the first projection 631 slides in the Z-direction within the first sliding hole 341, and the second projection 632 slides in the Z-direction within the second sliding hole 342.

As shown in fig. 17 and 18, the first portion includes a first support plate 64. The second part 3 comprises a second support plate 65. The first supporting plate 64 includes a first side portion 641 and a second side portion 642 which are connected in a bending manner. The first side portion 641 is rotatably coupled to the first side 31 of the third housing 30. In one embodiment, the first side 31 is provided with a first rotation axis 63. The first side portion 641 may be connected to the first side 31 through the first rotating shaft 63. The second side portion 642 is connected to the first rotation arm 61. At this time, when the first housing 10 rotates in the Y-Z plane with respect to the third housing 30, the first supporting plate 64 is also rotated in the Y-Z plane with respect to the third housing 30 via the first rotating arm 63 by the first rotating arm 61. The second support plate 65 includes a curved connection of a third side 651 and a fourth side 652. The third side 651 is pivotally connected to the second side 32 of the third housing 30. In one embodiment, the third side portion 651 can be connected to the second side 32 by a second hinge 68. The fourth side portion 652 is connected to the second rotating arm 62. At this time, when the second housing 20 rotates relative to the third housing 30 in the Y-Z plane, the second supporting plate 65 is also rotated relative to the third housing 30 in the Y-Z plane through the second rotating shaft 68 by the second rotating arm 62. As shown in fig. 18, when the electronic apparatus 100 is in a bent state, the first support plate 64 and the second support plate 65 are located on both sides of the flexible screen 40. As shown in fig. 20, when the electronic apparatus 100 is in the flat state, the movable plate 50, the first support plate 64 and the second support plate 65 are arranged side by side. The movable plate 50, the first support plate 64 and the second support plate 65 provide a supporting force for the flexible screen 40, so as to ensure the flatness of the flexible screen 40 and prevent the flexible screen 40 from being depressed when a user touches the flexible screen 40.

As shown in fig. 17 and 20, a first slide block 6421 is provided on the second side portion 642 of the first support plate 64, the first rotation arm 61 is provided with a first slide groove 612, and the first slide block 6421 is slidably mounted on the first slide groove 612. In this embodiment, the first slider 6421 has a crescent shape. The shape of the first sliding groove 612 is matched with the shape of the first slider 6421. At least a portion of the first sliding block 6421 may be received in the first sliding groove 612 and may slide relative to the first sliding groove 612. The first sliding groove 612 includes a first end 6121 and a second end 6222 disposed oppositely. The first end 6121 is the end of the first sliding slot 612 away from the first through hole 611. The second end 6122 is the end of the first sliding slot 612 near the first through hole 611. When the first casing 10 rotates relative to the third casing 30, the first casing 10 also drives the first rotation arm 61 to rotate relative to the third casing 30. At this time, during the rotation of the first rotation arm 61, since the size of the first sliding slot 612 is larger than that of the first slider 6421, the first slider 6421 slides within the first sliding slot 612. Therefore, while the first casing 10 drives the first supporting plate 64 to rotate relative to the third casing 30, the first casing 10 also drives the first supporting plate 64 to slide relative to the third casing 30. As shown in fig. 20, when the electronic device 100 is in the flattened state, the first slider 6421 is located at the second end 6122 of the first chute 612. Referring to fig. 21, when the electronic device 100 is in a bent state, the first sliding block 6421 slides to the first end 6121 of the first sliding groove 612.

Similarly, referring to fig. 17, by disposing the second slider 6521 on the fourth side portion 65 and disposing the second sliding slot 622 on the second rotating arm 62, the second casing 20 drives the second supporting plate 65 to rotate relative to the third casing 30, and simultaneously the second casing 20 also drives the second supporting plate 65 to slide relative to the third casing 30.

Further, as shown in fig. 22, the first part 1 further includes a first sliding plate 66. The first slide plate 66 includes a first rotating portion 661 and a first sliding portion 662 connected to the first rotating portion 661. The first support plate 64 includes a first sliding groove 643. The first sliding groove 643 penetrates the end face 6411 of the first side portion 641. The first sliding portion 662 is slidably fitted in the first sliding groove 643, and the first rotating portion 661 is rotatably connected to the first rotating shaft 63 while extending through an end face 6411 of the first side portion 641. At this time, when the electronic apparatus 100 is in the flat state, the first sliding portion 662 is accommodated in the first sliding groove 643. Of course, in other embodiments, when the electronic device 100 is in the flat state, the first sliding portion 662 may also partially extend out of the first sliding groove 643. Fig. 22 shows a portion of the first sliding portion 662 extending out of the first sliding groove 643. As shown in fig. 18 and 21, when the electronic apparatus 100 is in the bent state, a part of the first sliding portion 662 extends out of the first sliding groove 643, and the first sliding portion 662 extends out of the first sliding groove 643 for a longer distance than in the flat state. Therefore, when the electronic device 100 is bent from the flat state to the bent state, the first housing 10 rotates relative to the third housing 30, and the first housing 10 rotates the first rotating arm 61. The first support plate 64 is rotated relative to the third housing 30 by the first rotating arm 61 and the first rotating shaft 63 rotating through the first rotating part 661. In addition, during the rotation of the first support plate 64, the second side portion 642 of the first support plate 64 also slides relative to the first rotation arm 61, and at this time, the first sliding portion 662 slides relative to the first sliding groove 643 to slide the first support plate 64 relative to the first housing 10.

As shown in fig. 17 and 20, the third portion 5 includes an end cap 35. The end cap 35 covers the fixing plate 34. The end cap 35 covers a portion of the electronic device 100. In this embodiment, the end caps 35 are disposed at the ends of the first side 31 and the second side 32. The end cap 35, the first casing 10, the second casing 20, and the third casing 30 form an appearance part of the electronic device 100, so that the electronic device 100 has a simple and complete appearance, and the use experience of the electronic device 100 is improved.

The foregoing are alternative embodiments of the present application and it should be noted that modifications and refinements may occur to those skilled in the art without departing from the principle of the present application and are considered as the scope of the present application.
