[0028] The following is combined with Figures 1 to 11 This application describes an electronic device according to an embodiment of the present application.

[0029] like Figure 1 and Figure 6 As shown, an electronic device 100 according to some embodiments of this application includes: a first metal support 110; an antenna assembly 150 connected to the first metal support 110; a flexible screen 120 including an unfolding section 122 and a retractable section 124, the unfolding section 122 being located on a first side of the first metal support 110, and the retractable section extending from the first side of the first metal support 110 to a second side of the first metal support 110; a second metal support 130 disposed between the retractable section 124 and the first metal support 110, capable of sliding relative to the first metal support 110 with the retractable section 124, for supporting the retractable section 124; a metal sheet 160 spaced apart from the second metal support 130; and an insulating portion 170, the first end of which is connected to the metal sheet 160, and the second end of which is connected to the second metal support 130.

[0030] The second metal support 130 has an extended position and a closed position relative to the first metal support 110. When it is in the extended position, the metal sheet 160 is away from the antenna assembly 150, and the antenna assembly 150 radiates electromagnetic waves toward the target area. When it is in the closed position, the metal sheet 160 is located within the target area, and the antenna assembly 150 couples and excites the metal sheet 160, radiating electromagnetic waves through the metal sheet 160.

[0031] In the embodiment of the present application, the electronic device 100 comprises a first metal support 110, a second metal support 130 and a flexible screen 120. The first metal support 110 is a fixed support in the electronic device 100, serving as the main frame structure of the electronic device 100 for positioning and supporting other structures on the electronic device 100. The fixed end of the flexible screen 120 is connected to the first metal support 110, and part of the flexible screen 120 is distributed on the first side of the first metal support 110, which is divided into an unfolded section 122. Another part of the flexible screen 120 is wound from the first side of the first metal support 110 to the second side of the first metal support 110, which is divided into a storage section 124. The unfolded section 122 is exposed outside the shell assembly 180 and belongs to the screen area that can be used by the user, and the storage section 124 is hidden in the shell assembly 180 and serves as a backup unfolded part. The second metal support 130 is arranged on the second side of the first metal support 110 and between the storage section 124 and the first metal support 110 to support and position the storage section 124.

[0032] When the user needs to increase the display size, the second metal support 130 is driven to slide relative to the first metal support 110 in a first direction by the motor hinge structure, so as to increase the length of the unfolded section 122 and shorten the length of the storage section 124 by pushing the transition area of the unfolded section 122 and the storage section 124. Correspondingly, when the user does not need to use a large-size screen, the second metal support 130 slides in a second direction opposite to the first direction together with the storage section 124, the length of the storage section 124 is increased, and the length of the unfolded section 122 is reduced, so as to reduce the size of the electronic device 100 and reduce the difficulty of holding and storing.

[0033] On this basis, in order to avoid the screen stretching edge and the motor hinge structure, an antenna assembly 150 is arranged on the first metal support 110. The antenna assembly 150 transmits and receives communication signals by radiating electromagnetic waves to meet the communication needs of the electronic device 100. The radiation direction of the antenna assembly 150 fixed on the first metal support 110 is default, and electromagnetic waves are radiated to a target area. When the flexible screen 120 is in an unfolded state, the overlapping area of the first metal support 110 and the second metal support 130 is small, and the second metal support 130 avoids the target area and does not affect the normal work of the antenna assembly 150. Conversely, when the flexible screen 120 is in a storage state, the overlapping area of the first metal support 110 and the second metal support 130 is large, and the second metal support 130 is likely to shield the antenna assembly 150 in the target area, resulting in that the communication performance of the antenna assembly 150 in this state is affected.

[0034] To this end, the application is provided with the metal sheet 160 and the insulating part 170, the insulating part 170 is arranged on the second metal support 130, the metal sheet 160 is arranged on the insulating part 170, and the insulating part 170 plays a transition connection role between the metal sheet 160 and the second metal support 130, so as to avoid the contact between the metal sheet 160 and the second metal support 130, thereby constructing the suspended metal sheet 160 on the second metal support 130. In the process of switching the state of the flexible screen 120, the metal sheet 160 slides synchronously with the second metal support 130.

[0035] On this basis, the second metal support 130 has an unfolded position and a closed position relative to the first metal support 110. As shown in Figure 2 , the unfolded position corresponds to the unfolded state of the flexible screen 120, and in the unfolded position, the second metal support 130 is staggered with the first metal support 110, and the second metal support 130 and the metal sheet 160 avoid the target area radiated by the antenna assembly 150. At this time, the antenna assembly 150 can directly radiate electromagnetic waves to the outside of the electronic device 100 without being blocked, so that the electronic device 100 has reliable communication performance in the unfolded state. Among them, Figure 1 and Figure 2 , arrow a in the figure shows the target area radiated by the antenna assembly 150.

[0036] Correspondingly, as shown in Figure 7 , the closed position corresponds to the storage state of the flexible screen 120, and in the closed position, the second metal support 130 slides to the second side of the first metal support 110, the overlapping area is large, and the second metal support 130 affects the normal transmission of the electromagnetic waves radiated by the antenna. At the same time, the metal sheet 160 is located in the target area, and the antenna assembly 150 is used as the coupling feeding structure of the metal sheet 160 in this state, and the electromagnetic waves radiated by the antenna assembly 150 are coupled to excite the metal sheet 160, so as to radiate electromagnetic waves to the outside of the electronic device 100 through the metal sheet 160. Among them, Figure 6 and Figure 7 , arrow b in the figure shows the action area of the electromagnetic waves radiated by the excited metal sheet 160.

[0037] Therefore, by introducing the above structure layout, the antenna assembly 150 can radiate electromagnetic waves in different radiation modes when the second metal support 130 is in different positions, and specifically, in the unfolded position, the antenna assembly 150 is used to directly radiate electromagnetic waves to the target area by using the inherent function of the antenna assembly 150. In the closed position, the antenna assembly 150 is used as a feeding structure of the metal sheet 160, and the metal sheet 160 is used as an antenna to radiate electromagnetic waves to the outside of the electronic device 100 by means of the metal sheet 160 in the target area. Thus, the electronic device 100 can maintain good radiation performance in different states of the flexible screen 120, eliminate the adverse effects of the linkage structure of the flexible screen 120 on the antenna assembly 150, and solve the technical problem of poor communication performance of the electronic device 100 in a specific state of the flexible screen 120.

[0038] Further, the type of the antenna assembly 150 is not rigidly limited in this embodiment. The antenna assembly 150 can be a slot antenna in the following embodiments, and can also be a monopole antenna, a dipole antenna, or a helical antenna, which specifically meets the electromagnetic wave transmission requirement and the metal sheet 160 excitation requirement.

[0039] In this scheme, the antenna assembly 150 can be fixed at the end of the first metal support 110 and radiate electromagnetic waves to the second side of the first metal support 110. In this scheme, the metal sheet 160 is arranged at the corresponding end of the second metal support 130 to reduce the difficulty of exciting the metal sheet 160. The antenna assembly 150 can also be arranged on the first side of the first metal support 110 and radiate electromagnetic waves to the second side through the first metal support 110. In this scheme, a hole is needed to be opened at the corresponding position of the second metal support 130, and the metal sheet 160 is suspended in the hole through the insulating part 170 to ensure that the electromagnetic waves radiated by the antenna assembly 150 can excite the metal sheet 160. This embodiment does not rigidly limit the arrangement of the antenna assembly 150 and the metal sheet 160, and meets the requirement of the metal sheet 160 unfolding to avoid radiation and closing to receive excitation of radiation.

[0040] According to some embodiments of the present application, as shown in Figure 2 , Figure 7 and Figure 11 , the electronic device 100 further includes: a convex rib 140 arranged on the first metal support 110 and away from the unfolded section 122, including a first through hole 142, a first end of the first through hole 142 facing the metal sheet 160; the antenna assembly 150 is arranged opposite to a second end of the first through hole 142, and the antenna assembly 150 radiates electromagnetic waves through the first through hole 142.

[0041] In this embodiment, the first metal support 110 is provided with a protrusion 140, which is disposed on the surface facing the second metal support 130, protrudes in the direction away from the unfolded section 122 of the flexible screen 120, and is disposed in a staggered manner with the second metal support 130. On the basis of this, the protrusion 140 is provided with a first through hole 142, which is transversely disposed through the protrusion 140, and the first end of the first through hole 142 faces the suspended metal sheet 160, and the electromagnetic wave emitting end of the antenna assembly 150 is disposed opposite the second end of the first through hole 142.

[0042] Specifically, when the second metal support 130 is in the unfolded position, the first through hole 142 is used as a slot antenna, and the antenna assembly 150 radiates electromagnetic waves to the target area through the first through hole 142. When the second metal support 130 is in the closed position, the first through hole 142 is used as a coupling slot, and the electromagnetic waves radiated by the first through hole 142 excite the metal sheet 160 suspended on the second metal support 130 to realize the emission and reception of signals through the metal sheet 160.

[0043] By disposing the protrusion 140 including the first through hole 142 on the first metal support 110 and disposing the antenna assembly 150 opposite the first through hole 142, the antenna assembly 150 can radiate electromagnetic waves transversely to the second metal support 130 through the first through hole 142. Thus, the metal sheet 160 and the insulating portion 170 can be arranged on the end of the second metal support 130 facing the protrusion 140, so as to eliminate the scheme of opening a hole on the second metal support 130 and arranging the insulating portion 170 and the metal sheet 160 in the hole. Further, the technical effects of reducing the structural complexity of the combination of the metal sheet 160, the insulating portion 170 and the second metal support 130, reducing the improvement range of the second metal support 130, reducing the arrangement difficulty of the metal sheet 160, and compressing the cost of the electronic device 100 are achieved.

[0044] According to some embodiments of the present application, as shown in Figure 6 , Figure 7 and Figure 11 , the metal sheet 160 includes: a first metal sheet 162, a first surface of the first metal sheet 162 facing the first through hole 142; a second metal sheet 164, which is connected to the first metal sheet 162, and a first surface of the second metal sheet 164 facing the first metal support 110; wherein, when the second metal support 130 is in the unfolded position, the target area is located between the protrusion 140 and the first metal sheet 162.

[0045] In this embodiment, the metal sheet 160 is divided into a first metal sheet 162 and a second metal sheet 164 according to the orientation of the metal sheet 160. Specifically, the first metal sheet 162 is arranged opposite to the protruding rib 140, and a first surface of the first metal sheet 162 faces the first through hole 142 on the protruding rib 140. The second metal sheet 164 is bent away from the protruding rib 140 relative to the first metal sheet 162, and specifically, a first surface of the second metal sheet 164 faces the first metal support 110, and the first surface of the second metal sheet 164 is spaced apart from the first metal support 110.

[0046] When the second metal support 130 is in the unfolded external position, the first metal sheet 162 is away from the protruding rib 140, and a target area is enclosed between the protruding rib 140 and the first surface of the first metal sheet 162. At this time, the antenna assembly 150 radiates electromagnetic waves to the target area through the first through hole 142.

[0047] When the second metal support 130 is in the closed position, the first metal sheet 162 is close to the protruding rib 140 and enters the aforementioned target area. The electromagnetic waves output by the antenna assembly 150 excite the metal sheet 160, and then the metal sheet 160 excited as an antenna radiates electromagnetic waves to the angle area between the first metal sheet 162 and the second metal sheet 164, so as to eliminate the influence of the second metal support 130 on electromagnetic wave radiation.

[0048] By arranging the second metal sheet 164 bent relative to the first metal sheet 162, on the one hand, the frequency of the finally radiated electromagnetic waves can be adjusted by extending the total length of the metal sheet 160, so as to ensure that the radiated electromagnetic waves can meet the communication needs of the electronic device 100. On the other hand, the angle and range of electromagnetic wave radiation can be adjusted by adjusting the angle between the second metal sheet 164 and the first metal sheet 162, so as to ensure that the electromagnetic waves can avoid other metal structures such as the second metal support 130, so as to optimize the radiation performance of the electromagnetic waves and further strengthen the communication effect of the electronic device 100.

[0049] According to some embodiments of the present application, as shown in Figure 6 , Figure 7 and Figure 11 , the second surface of the first metal sheet 162 is covered by the insulating part 170; and the second surface of the second metal sheet 164 is covered by the insulating part 170.

[0050] In this embodiment, the first metal sheet 162 is connected to the insulating part 170 and is shielded by the insulating part 170 on the second surface away from the protruding rib 140. Similarly, the second metal sheet 164 is connected to the insulating part 170 and is shielded by the insulating part 170 on the second surface away from the first metal support 110.

[0051] By setting the insulating part 170 capable of fully covering the second surface of the two metal sheets 160, the suspension feature of the metal sheets 160 can be ensured, and it is ensured that the metal sheets 160 will not be in contact with the second metal support 130, the flexible screen 120 and other metal structures, so as to avoid the influence of the radiation characteristics of the metal sheets 160 by other metal structures. Further, the technical effects of improving the radiation reliability and radiation accuracy of the metal sheets 160 as an antenna and improving the communication stability of the electronic device 100 are achieved.

[0052] According to some embodiments of the present application, as shown in Figure 2 and Figure 7 , the first metal support 110 and the second metal support 130 are both in the form of a plate; the first metal support 110 and the second metal support 130 are parallel and spaced apart.

[0053] In this embodiment, the first metal support 110 and the second metal support 130 are both metal plate members. The first metal support 110 and the second metal support 130 are parallel to each other and spaced apart. The first metal support 110 is used to support the unfolded section 122 of the flexible screen 120, and the second metal support 130 is used to support the storage section 124 of the flexible screen 120.

[0054] By setting the first metal support 110 and the second metal support 130 as plate members, the flexible screen 120 can be effectively supported, so that the flexible screen 120 can be laid flat on the plate members, avoiding the flexible screen 120 from collapsing, curling and bending. Thus, the possibility of creases on the unfolded section 122 is reduced, and the storage section 124 is prevented from being stuck inside the electronic device 100. Further, the technical effects of optimizing the use experience of the flexible screen 120 and reducing the failure rate of the electronic device 100 are achieved.

[0055] According to some embodiments of the present application, as shown in Figure 2 , Figure 7 and Figure 11 , the antenna assembly 150 comprises: a dielectric layer 152; a metal layer 154 disposed on the dielectric layer 152 and comprising a second through hole 1542, the second through hole 1542 being in butt joint with the second end of the first through hole 142; a feed line 156 disposed on the dielectric layer 152 and away from the metal layer 154; the feed line 156 comprises a first section 1562 and a second section 1564, the first section 1562 being used to connect a signal source, and the second section 1564 being arranged opposite to the second through hole 1542.

[0056] In this embodiment, the structure of the antenna assembly 150 is described. Specifically, the antenna assembly 150 includes a dielectric layer 152, a metal layer 154, and a feed line 156. Different structures are made on both sides of the dielectric layer 152, the lower layer is made into a microstrip wire as the feed line 156, and the upper layer is made into metal as the metal ground of the feed line 156. On this basis, a second through hole 1542 is opened on the metal layer 154 to structure the antenna assembly 150 as a slot antenna. Among them, the microstrip feed line 156 is divided into a first section 1562 and a second section 1564, the first section 1562 is used to connect the signal source to obtain electromagnetic energy from the signal source, and the second section 1564 is tightly attached to the dielectric layer 152, and the second section 1564 is arranged opposite to the second through hole 1542 on the metal layer 154, so that electromagnetic energy can be radiated outward through the second through hole 1542.

[0057] In the assembly process, the metal layer 154 of the antenna assembly 150 is attached to the first protruding rib 140, and the second through hole 1542 is aligned with the first through hole 142 to ensure that the electromagnetic waves output by the slot antenna can be radiated outward through the first through hole 142.

[0058] By structuring the antenna assembly 150 as a slot antenna, the antenna assembly 150 itself can be used as an antenna while also being used as a structure for slot coupling feeding, thereby improving the feeding effect of the antenna assembly 150 on the metal sheet 160 in the storage state.

[0059] According to some embodiments of the present application, as shown in Figure 7 and Figure 11 , the cross section of the first through hole 142 and the cross section of the second through hole 1542 are both rectangular; the cross-sectional size of the first through hole 142 is greater than or equal to the cross-sectional size of the second through hole 1542.

[0060] In this embodiment, the first through hole 142 and the second through hole 1542 are both rectangular holes, and the cross-sectional size of the first through hole 142 is greater than or equal to the cross-sectional size of the second through hole 1542. By structuring the first through hole 142 and the second through hole 1542 as elongated rectangular holes, the transmission effect of electromagnetic waves can be improved to improve the radiation performance of the antenna assembly 150. By setting the first through hole 142 with a size greater than or equal to the second through hole 1542, it can be ensured that the first through hole 142 will not block the electromagnetic waves output by the antenna assembly 150, so as to ensure that the antenna assembly 150 can obtain good antenna radiation performance.

[0061] According to some embodiments of the present application, as shown in Figure 7 and Figure 11 , the length direction of the second section 1564 is perpendicular to the length direction of the second through hole 1542.

[0062] In this embodiment, the second section 1564 attached to the dielectric layer 152 is perpendicular to the elongated second via hole 1542, so as to ensure excellent radiation performance of the antenna assembly 150.

[0063] Specifically, as shown in Figure 7 the length direction of the first via hole 142 and the second via hole 1542 is perpendicular to the height direction of the first protruding rib 140, the extension direction of the second section 1564 and the first section 1562 is consistent with the length direction of the dielectric layer 152. As shown in Figure 11 the length direction of the first via hole 142 and the second via hole 1542 is consistent with the height direction of the first protruding rib 140, the second section 1564 is bent by 90° relative to the first section 1562, so as to ensure the perpendicular relationship between the second section 1564 and the second via hole 1542.

[0064] wherein the transverse slotting and longitudinal slotting schemes belong to two embodiments of the present application, and in fact the present application does not rigidly limit the slotting direction of the first via hole 142 and the second via hole 1542, and the length direction of the first via hole 142 and the second via hole 1542 can be 30°, 45° or 60° to the height direction of the first protruding rib 140, as long as the second section 1564 is adjusted correspondingly.

[0065] According to some embodiments of the present application, the first via hole 142 is filled with plastic.

[0066] In this embodiment, the first via hole 142 is filled with plastic, and the filled plastic can eliminate the hole structure on the first protruding rib 140, and the plastic will not affect the normal transmission of electromagnetic waves. By filling the first via hole 142 with plastic, on the one hand, the first via hole 142 can be prevented from being directly exposed in the user's field of view in the unfolded state, so as to improve the consistency of the exposed surface of the electronic device 100 and reduce the sense of strangeness of the appearance of the electronic device 100. On the other hand, the filled plastic can block pollutants, so as to avoid the pollutants accumulated in the first via hole 142 from affecting the transmission effect of electromagnetic waves, thereby improving the communication reliability of the electronic device 100.

[0067] According to the foregoing embodiments, the working frequency of the antenna assembly 150 can be controlled by the length of the second via hole 1542, and generally the length of the second via hole 1542 is 1 / 2 of the working wavelength, and the width of the second via hole 1542 can be adjusted according to the actual antenna impedance matching requirement. At the same time, the length of the microstrip feed line 156 generally needs to exceed the center of the second via hole 1542, and the optimal length of the exceeding part is 1 / 4 of the working wavelength, so as to achieve the best radiation of electromagnetic energy, and generally the width of the microstrip feed line 156 is the width of the 50-ohm microstrip line. The propagation area of electromagnetic waves is as shown in Figure 2As shown by the region a indicated by the middle arrow, electromagnetic waves are emitted from the signal source, pass through the microstrip feed line 156 to excite the second through hole 1542, and then radiate into the air through the first through hole 142 on the first protruding rib 140, thereby achieving signal transmission and reception.

[0068] According to some embodiments of the present application, as shown in Figure 3 、 Figure 4 and Figure 5 , the electronic device 100 further comprises a shell assembly 180, the first metal support 110, the second metal support 130, the antenna assembly 150 and the receiving section 124 are all arranged in the shell assembly 180, and the unfolding section 122 is arranged at the opening of the shell assembly 180.

[0069] In this embodiment, the electronic device 100 further comprises a shell assembly 180, which is composed of a first shell 182, a second shell 184 and a back plate 186.

The back plate 186 is divided into two parts, one part is fixed on the back side of the first shell 182, and the other part is fixed on the back side of the second shell 184, so as to shield the internal structure. The front side opposite to the back plate 186 is the opening of the shell assembly 180, and the unfolding section 122 of the flexible screen 120 is embedded in the opening.

[0070] As shown in Figure 3 、 Figure 4 and Figure 5 , when the electronic device 100 is in the receiving state, the first shell 182 and the second shell 184 are close to each other, and a gap is left between the two back plates 186, which is aligned with the radiation port surrounded by the first protruding rib 140 and the second protruding rib 140, so that the electromagnetic waves can radiate outward through the radiation port and the gap in sequence. As shown in Figure 8 、 Figure 9 and Figure 10 , when the electronic device 100 switches to the unfolding state, the second shell 184 and the back plate 186 thereon extend outward, and the first metal support 110 between the two back plates 186 is exposed. For the antenna assembly 150, the exposed area has better clearance, and the antenna assembly 150 can directly radiate electromagnetic waves outward through the first through hole 142.

[0071] According to some embodiments of the present application, as shown in Figure 1 and Figure 6 , the electronic device 100 further comprises a circuit board 190 arranged in the shell assembly 180 and connected with the antenna assembly 150.

[0072] In this embodiment, the electronic device 100 further comprises a circuit board 190, which is arranged in the first housing 182 and connected with the first metal support 110 through the antenna assembly 150. The circuit board 190 is used as a signal source of the antenna assembly 150 on one hand, and the circuit board 190 radiates electromagnetic energy to the external environment through the antenna assembly 150 in the working process to realize the transmission and reception of signals. The circuit board 190 is also used as a control structure of the electronic device 100, and the control circuit thereon can control the motor hinge structure to drive the second housing 184 and the second metal support 130 to slide according to the unfolding instruction and the storage instruction, so as to realize the automatic unfolding and automatic storage of the electronic device 100, thereby canceling the operation mode of manual pushing and pulling by the user.

[0073] According to some embodiments of the present application, as shown in Figure 1 and Figure 6 The unfolding section 122 is connected with the shell assembly 180, and the storage section 124 is connected with the second metal support 130, and the electronic device 100 further comprises a roller 188 connected with the second metal support 130, and the storage section 124 is wound to the second side of the first metal support 110 through the roller 188; and a driving assembly 189 arranged on the first metal support 110 and connected with the second metal support 130, and used for driving the second metal support 130 to reciprocate along the first direction.

[0074] In this embodiment, the unfolding section 122 of the flexible screen 120 is fixed on the shell assembly 180, and specifically connected with the first housing 182, and the storage section 124 is connected with the movable second metal support 130. On this basis, the electronic device 100 further comprises a roller 188 and a driving assembly 189, the roller 188 is rotationally connected with the second metal support 130, and the unfolding section 122 is wound to the second metal support 130 located on the second side of the first metal support 110 through the circumferential surface of the roller 188. The driving assembly 189 is connected with the first metal support 110, and the driving assembly 189 is used for driving the second metal support 130 to slide relative to the first metal support 110. Specifically, a motor hinge structure can be selected as the driving assembly 189, and an electric telescopic cylinder and other mechanisms can also be selected to realize the driving, and the specific structure form of the driving assembly 189 is not limited in this embodiment.

[0075] When the user needs to increase the display size, the driving assembly 189 drives the second metal support 130 to slide relative to the first metal support 110 along the first direction (such as the horizontal direction) to unfold the flexible screen 120, and the display size of the electronic device 100 is increased. Figure 1As indicated by arrow c, the second metal support 130 and roller 188 slide, during which the length of the unfolding section 122 increases and the length of the retracting section 124 decreases by pushing the transition area between the unfolding section 122 and the retracting section 124. Accordingly, when the user does not need to use the large screen, the drive assembly 189 drives the second metal support 130 and roller 188 in a second direction opposite to the first direction (e.g., as shown by arrow c). Figure 6 (As shown by the middle arrow d) Slide, during which the length of the storage section 124 is increased and the length of the unfolded section 122 is reduced by pulling the flexible screen 120, so as to reduce the size of the electronic device 100 and reduce the difficulty of holding and storing.

[0076] Meanwhile, during the adjustment of the display size of the flexible screen 120, the roller 188 ensures the smoothness of the flexible screen 120's curling or unfolding movement by rotating, preventing the flexible screen 120 from jamming. Furthermore, the first metal support 110, the second metal support 130, and the roller 188 provide effective support for the flexible screen 120, ensuring that the flexible screen 120 is always in a taut state and preventing unevenness.
