Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to an electronic equipment. Background Art

[0002] In the related art, the roll-up screen mobile phone is the size of a normal mobile phone in the normal state, and the display area can be increased after the mobile phone is rolled up and stretched, but the frame on the side of the mobile phone screen that can be rolled up cannot be used as an antenna, and the antenna needs to be arranged inside the frame. However, the structure associated with the retractable screen will interfere with the normal operation of the antenna after switching the screen state, so that the communication ability of the mobile phone is affected. Summary of the invention

[0003] The present application aims to provide an electronic device that at least solves one of the problems that the antenna arranged on the inner side of the frame is easily affected by the screen linkage structure and the communication performance of the mobile phone in different screen states has a large difference.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] The embodiment of the present application provides an electronic device, comprising: a first metal support; a flexible screen, comprising an unfolding section and a storage section, wherein the unfolding section is located at a first side of the first metal support, and the storage section is wound from the first side of the first metal support to the second side of the first metal support; a second metal support, disposed between the storage section and the first metal support, capable of sliding relative to the first metal support along with the storage section, for supporting the storage section; a first convex rib, disposed on the first metal support, away from the unfolding section, comprising a first through hole, wherein a first end of the first through hole faces the second metal support; an antenna assembly, disposed opposite to the second end of the first through hole;

[0006] Among them, the second metal support member has an extended position and a closed position relative to the first metal support member; when in the extended position, the second metal support member is away from the first through hole, and the antenna assembly radiates electromagnetic waves through the first through hole; when in the closed position, the second metal support member is close to the first through hole, and the second metal support member and the first metal support member enclose a resonant cavity connected to the first through hole, and the antenna assembly radiates electromagnetic waves through the first through hole and the resonant cavity.

[0007] In an embodiment of the present application, by providing a first rib, the antenna assembly can radiate electromagnetic waves laterally toward the inner end of the second metal support member with the help of the first through hole. Compared with the technical solution of arranging the antenna assembly on the first metal support member and radiating electromagnetic waves longitudinally toward the second side of the first metal support member, this radiation method is less affected by the sliding second metal support member, and the radiated electromagnetic waves will not be blocked by the second metal support member during the sliding process.

[0008] On this basis, the antenna assembly can stimulate different antenna radiation modes when the second metal support is in different positions, specifically using the first through hole for slot radiation in the unfolded position, and using the through hole and the resonant cavity for resonant radiation in the closed position. This allows the electronic device to maintain good radiation performance in different flexible screen states, eliminates the adverse effects of the flexible screen linkage structure on the antenna assembly, and solves the technical problem of poor communication performance of the electronic device in a specific flexible screen state.

[0029] Combine the following Figures 1 to 12 An electronic device according to an embodiment of the present application is described.

[0030] like Figure 1 and Figure 6 As shown, in some embodiments of the present application, an electronic device 100 is provided, and the electronic device 100 includes: a first metal support 110; a flexible screen 120, including an unfolding section 122 and a storage section 124, the unfolding section 122 is located on the first side of the first metal support 110, and the storage section 124 is wound from the first side of the first metal support 110 to the second side of the first metal support 110; a second metal support 130, which is arranged between the storage section 124 and the first metal support 110 and can slide relative to the first metal support 110 along with the storage section 124, and is used to support the storage section 124; a first convex rib 140, which is arranged on the first metal support 110, away from the unfolding section 122, and includes a first through hole 142, and the first end of the first through hole 142 faces the second metal support 130; an antenna assembly 150, which is arranged opposite to the second end of the first through hole 142;

[0031] Among them, the second metal support member 130 has an extended position and a closed position relative to the first metal support member 110; when in the extended position, the second metal support member 130 is away from the first through hole 142, and the antenna assembly 150 radiates electromagnetic waves through the first through hole 142; when in the closed position, the second metal support member 130 is close to the first through hole 142, and the second metal support member 130 and the first metal support member 110 enclose a resonant cavity 132 connected to the first through hole 142, and the antenna assembly 150 radiates electromagnetic waves through the first through hole 142 and the resonant cavity 132.

[0032] In the embodiment of the present application, the electronic device 100 includes a first metal support 110, a second metal support 130 and a flexible screen 120. The first metal support 110 is a fixed support inside the electronic device 100, and serves as the main frame structure of the electronic device 100, and is used to position and support 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. This part of the flexible screen 120 is divided into an unfolding section 122, and 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, and is divided into a storage section 124. Among them, the unfolding 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 as a spare unfolding part. The second metal support member 130 is disposed on the second side of the first metal support member 110 and is disposed between the receiving section 124 and the first metal support member 110 to support and position the receiving section 124 .

[0033] When the user needs to increase the display size, the motor hinge structure drives the second metal support 130 to slide relative to the first metal support 110 along the first direction, so as to increase the length of the unfolding section 122 and shorten the length of the storage section 124 by pushing the transition area between the unfolding 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 along with the storage section 124 in a second direction opposite to the first direction, the length of the storage section 124 increases, and the length of the unfolding section 122 decreases, so as to reduce the size of the electronic device 100 and reduce the difficulty of holding and storage.

[0034] On this basis, in order to avoid the telescopic edge of the screen and the motor hinge structure, the antenna assembly 150 is arranged on the first metal support 110, and the antenna assembly 150 transmits and receives communication signals by radiating electromagnetic waves to meet the communication needs of the electronic device 100. Among them, the radiation direction of the antenna assembly 150 fixed on the first metal support 110 is default. When the flexible screen 120 is in the 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 will not affect the normal operation of the antenna assembly 150. On the contrary, when the flexible screen 120 is in the retracted 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 very likely to block the antenna assembly 150 in the radiation direction of the antenna assembly 150, resulting in the communication performance of the antenna assembly 150 in this state being affected.

[0035] In this regard, the present application sets a first rib 140 and optimizes the arrangement position of the antenna assembly 150. The first rib 140 is set on the surface of the first metal support 110 facing the second metal support 130, and is staggered with the second metal support 130 and opposite to the inner end of the second metal support 130. The first rib 140 is provided with a first through hole 142 that runs horizontally through it, and the first end of the first through hole 142 faces the inner end of the second metal support 130. The antenna assembly 150 is arranged opposite to the second end of the first through hole 142 to radiate electromagnetic waves outward through the first through hole 142.

[0036] By setting the first rib 140, the antenna component 150 can radiate electromagnetic waves laterally toward the inner end of the second metal support 130 with the help of the first through hole 142. Compared with the technical solution of arranging the antenna component 150 on the first metal support 110 and radiating electromagnetic waves longitudinally toward the second side of the first metal support 110, this radiation method is less affected by the sliding second metal support 130, and the radiated electromagnetic waves will not be blocked by the second metal support 130 during the sliding process.

[0037] On this basis, the second metal support member 130 has an extended position and a closed position relative to the first metal support member 110. Figure 2 As shown, the unfolded position corresponds to the unfolded state of the flexible screen 120. In the unfolded position, the second metal support 130 is staggered with the first metal support 110, and the inner end of the second metal support 130 is away from the first through hole 142. At this time, the second metal support 130 will not interfere with the antenna assembly 150, and the antenna assembly 150 can directly radiate electromagnetic waves outward through the first through hole 142, so that the electronic device 100 has reliable communication performance in the unfolded state. Among them, Figure 1 and Figure 2 The area indicated by the arrow a is the radiation area of ​​the electromagnetic wave.

[0038] Correspondingly, if Figure 7 As shown, the closed position corresponds to the storage state of the flexible screen 120. In the closed position, the second metal support 130 is located on the second side of the first metal support 110, the overlapping area is large, and the inner end of the second metal support 130 is close to the first through hole 142. At the same time, a gap connecting the first through hole 142 is left between the first metal support 110 and the second metal support 130, and the gap forms a resonant cavity 132. At this time, the antenna assembly 150 and the first through hole 142 are used as a coupled feeding structure of the resonant cavity 132, and the electromagnetic waves radiated through the first through hole 142 excite the resonance of the resonant cavity 132, so that after the resonance obtains the required frequency, the electromagnetic waves are radiated outward through the gap between the first rib 140 and the second metal support 130. Among them, Figure 6 and Figure 7The middle arrow b shows the radiation area of ​​the electromagnetic wave.

[0039] It can be seen that, by introducing the above-mentioned structural layout, the present application enables the antenna assembly 150 to respectively excite different antenna radiation modes when the second metal support 130 is in different positions, specifically, using the first through hole 142 for slot radiation in the unfolded position, and using the through hole and the resonant cavity 132 for resonant radiation in the closed position. 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.

[0040] Furthermore, in this embodiment, there is no rigid limitation on the type of antenna component 150. The antenna component 150 can be a slot antenna in the embodiment below, or a monopole antenna, a vibrator antenna or a helical antenna can be selected as the antenna component 150, which can specifically meet the requirements of electromagnetic wave transmission and the excitation requirements of the resonant cavity 132.

[0041] According to some embodiments of the present application, Figure 2 , Figure 7 and Fig.12 As shown, the electronic device 100 also includes: a conductive part 160, which is arranged on the first metal support 110 or the second metal support 130; when the second metal support 130 is in a closed position, the conductive part 160 connects the first metal support 110 and the second metal support 130, and the first metal support 110, the second metal support 130 and the conductive part 160 enclose a resonant cavity 132.

[0042] In this embodiment, the electronic device 100 further includes a conductive portion 160, which is disposed in the interval between the first metal support 110 and the second metal support 130 and fixed on one of the first metal support 110 and the second metal support 130. When the second metal support 130 is located in the unfolded position, the conductive portion 160 is located in the staggered area between the first metal support 110 and the second metal support 130. When the second metal support 130 moves to the closed position, the two ends of the conductive portion 160 are respectively connected to the first metal support 110 and the second metal support 130. At this time, the first metal support 110, the second metal support 130 and the conductive portion 160 jointly enclose the above-mentioned resonant cavity 132.

[0043] By providing the conductive portion 160, the resonant frequency of the resonant cavity 132 can be adjusted by limiting the length of the resonant cavity 132, so that the electromagnetic waves radiated through the first through hole 142 are converted into electromagnetic waves with the required frequency after the resonance of the resonant cavity 132, so as to ensure that the electromagnetic waves finally radiated to the outside of the electronic device 100 can meet the communication requirements. This can achieve the technical effect of improving the communication effect of the electronic device 100 and optimizing the user experience of the electronic device 100.

[0044] Specifically, the position of the conductive part 160 can be adjusted according to the required resonant frequency. There are multiple conductive parts 160, and the multiple conductive parts 160 are spaced apart on a straight line perpendicular to the length direction of the resonant cavity 132. Specifically, two spaced conductive parts 160 can be set, thereby further improving the resonant accuracy of the resonant cavity 132 and improving communication reliability.

[0045] Furthermore, a metal spring sheet may be selected as the conductive part 160 , or a conductive foam may be selected as the conductive part. The present application does not impose any rigid restrictions on the specific material of the conductive part 160 , and it is sufficient to meet the electrical connection requirements.

[0046] According to some embodiments of the present application, Fig.11 As shown, the electronic device 100 also includes: a first boss 112, which is arranged on the first metal support member 110, and a conductive part 160 is arranged on the first boss 112; a second boss 134, which is arranged on the second metal support member 130, and when the second metal support member 130 is in a closed position, the conductive part 160 contacts the second boss 134.

[0047] In this embodiment, the electronic device 100 also includes a first boss 112 and a second boss 134. The first boss 112 is arranged on the first metal support 110, and the second boss 134 is arranged on the second metal support 130. The first boss 112 and the second boss 134 are both located in the gap between the first support and the second support, and are arranged relative to each other. The conductive part 160 is fixed on the first boss 112. When the second metal support 130 is in the unfolded position, the second boss 134 is staggered with the conductive part 160 to prevent the conductive part 160 from scratching the second metal support 130 during the sliding process of the second metal support 130. Correspondingly, when the second metal support 130 is in the closed position, the suspended end of the conductive part 160 abuts against the end face of the second boss 134 to connect the second metal support 130, thereby acting as a lower point to adjust the resonant frequency of the resonant cavity 132.

[0048] It can be seen that by setting the boss structure, on the one hand, the conductive part 160 can be separated from the second metal support 130 in the non-working state, on the one hand, it plays a role in protecting the conductive part 160 and the second metal support 130, and on the other hand, it prevents the conductive part 160 from affecting the radiation performance of the antenna assembly 150 in the unfolded state. At the same time, the boss structure can also adjust the impedance characteristics in the stored state, and obtain a better electromagnetic wave radiation effect. Thereby achieving the technical effect of improving the structural reliability of the electronic device 100 and improving the communication performance of the electronic device 100.

[0049] According to some embodiments of the present application, Figure 2 , Figure 6 and Figure 7 As shown, the electronic device 100 also includes: a second rib 170, which is arranged on the second metal support 130 and is opposite to the first rib 140; when the second metal support 130 is in a closed position, a radiation port 172 connected to the resonant cavity 132 is formed between the first rib 140 and the second rib 170.

[0050] In this embodiment, the second metal support 130 is further provided with a second rib 170, which is arranged at the inner end of the second metal support 130 and is arranged opposite to the first rib 140. When the second metal support 130 is in the unfolded position, the second rib 170 is away from the first rib 140, and the second rib 170 avoids the radiation area of ​​the antenna assembly 150. When the second metal support 130 moves to the closed position, the second rib 170 is close to the first rib 140 and blocks the electromagnetic wave transmission of the first through hole 142. At this time, a radiation port 172 is defined between the first rib 140 and the second rib 170, and the inlet of the radiation port 172 is connected to the resonant cavity 132, and the outlet faces the outside of the electronic device 100. The electromagnetic wave transmitted by the through hole first enters the resonant cavity 132, and then radiates to the outside of the electronic device 100 through the radiation port 172, so as to realize the transmission and reception of signals.

[0051] By providing the second convex rib 170, on the one hand, it can play a role in shielding the first through hole 142 in the storage state, ensuring that the first through hole 142 can be used as a coupling structure of the resonant cavity 132, ensuring that the electromagnetic wave can be output after resonance. On the other hand, by providing the second convex rib 170 to enclose the radiation outlet 172, it can play a role in adjusting the radiation direction, ensuring that the electromagnetic wave finally output can avoid the electronic device 100 itself. The technical effect of optimizing the electromagnetic wave transmission path and improving the communication performance of the electronic device 100 is achieved.

[0052] According to some embodiments of the present application, Figure 2 , Figure 6 and Figure 7 As shown, the radiation opening 172 gradually increases in size in a direction away from the resonant cavity 132 .

[0053] In the embodiment, the shape of the radiation port 172 is described. Specifically, in the direction away from the resonant cavity 132, the cross-sectional size of the radiation port 172 gradually increases to form a horn-shaped radiation port 172. By providing the horn-shaped radiation port 172, the radiation range of the electromagnetic wave can be expanded, thereby improving the communication performance of the electronic device 100 by expanding the coverage area of ​​the electromagnetic wave.

[0054] Specifically, a first inclined surface may be provided on the first convex rib 140, and a second inclined surface may be provided on the second convex rib 170, and the first inclined surface may be inclined in a direction away from the second convex rib 170 in a direction from the root to the top of the first convex rib 140. Correspondingly, the second inclined surface may be inclined in a direction away from the first convex rib 140 in a direction from the root to the top of the second convex rib 170, so that a bell mouth is enclosed by the first inclined surface and the second inclined surface. This structure has low complexity and low processing difficulty, which is conducive to reducing the cost of constructing the radiation port 172.

[0055] According to some embodiments of the present application, Figure 7 and Fig.12 As shown, the first metal support member 110 and the second metal support member 130 are both plate-shaped; the first metal support member 110 and the second metal support member 130 are parallel, and the first metal support member 110 and the second metal support member 130 are spaced apart.

[0056] In this embodiment, the first metal support member 110 and the second metal support member 130 are both metal plates. The first metal support member 110 and the second metal support member 130 are parallel to each other, and there is a gap between the first metal support member 110 and the second metal support member 130. The first plate surface of the first metal support member 110 is used to support the unfolding section 122 of the flexible screen 120, and the second plate surface is opposite to the third plate surface of the second metal support member 130. In the storage state, the second plate surface and the third plate surface cooperate with the conductive part 160 horizontally arranged therebetween to enclose the resonant cavity 132. The fourth plate surface of the second metal support member 130 is used to support the storage section 124 of the flexible screen 120.

[0057] By setting the first metal support 110 and the second metal support 130 as plates, on the one hand, it can effectively support the flexible screen 120, so that the flexible screen 120 can be laid flat on the plate to prevent the flexible screen 120 from collapsing, curling and bending. Thereby reducing the possibility of creases in the unfolding section 122 and preventing the storage section 124 from getting stuck inside the electronic device 100. Thereby achieving the technical effect of optimizing the user experience of the flexible screen 120 and reducing the failure rate of the electronic device 100. On the other hand, the first metal support 110 and the second metal support 130 are designed as two parallel and spaced large-area metal plates, so that a resonant cavity 132 can be easily formed between the two, thereby rationally utilizing the inherent shape of the support structure, reducing the extent of changes to the electronic device 100 caused by the technical solution, and thereby reducing the difficulty and cost of improving the electronic device 100.

[0058] According to some embodiments of the present application, Figure 2 , Figure 7 and Fig.12 As shown, the antenna assembly 150 includes: a dielectric layer 152; a metal layer 154, which is arranged on the dielectric layer 152 and includes a second through hole 1542, and the second through hole 1542 is connected to the second end of the first through hole 142; a feed line 156, which is arranged on the dielectric layer 152 and away from the metal layer 154; the feed line 156 includes a first section 1562 and a second section 1564, the first section 1562 is used to connect to a signal source, and the second section 1564 is arranged opposite to the second through hole 1542.

[0059] 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, a microstrip feed line is made in the lower layer as the feed line 156, and a metal is made in the upper layer 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 construct 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, the second section 1564 is closely 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 the electromagnetic energy can be radiated outward through the second through hole 1542.

[0060] During the assembly process, the metal layer 154 of the antenna assembly 150 is attached to the first rib 140 , and the second through hole 1542 is aligned with the first through hole 142 , ensuring that the electromagnetic waves output by the slot antenna can be radiated outward through the first through hole 142 .

[0061] By constructing the antenna assembly 150 as a slot antenna, the antenna assembly 150 itself can be used as an antenna and can also be used as a slot coupling feeding structure, thereby improving the feeding effect of the antenna assembly 150 on the resonant cavity 132 in the stored state.

[0062] According to some embodiments of the present application, Figure 7 and Fig.12 As shown, the cross-sections of the first through hole 142 and the second through hole 1542 are both rectangular; the cross-section size of the first through hole 142 is greater than or equal to the cross-section size of the second through hole 1542 .

[0063] 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 configuring 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 to be greater than or equal to the size of 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.

[0064] According to some embodiments of the present application, Figure 7 and Fig.12 As shown, the length direction of the second section 1564 is perpendicular to the length direction of the second through hole 1542 .

[0065] In this embodiment, the second section 1564 attached to the dielectric layer 152 is vertically disposed to the elongated second through hole 1542 to ensure that the antenna assembly 150 can obtain excellent radiation performance.

[0066] Specifically, Figure 7 As shown, when the length direction of the first through hole 142 and the second through hole 1542 is perpendicular to the height direction of the first 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. Fig.12 As shown, when the length direction of the first through hole 142 and the second through hole 1542 is consistent with the height direction of the first rib 140, the second section 1564 is bent 90° relative to the first section 1562 to ensure the vertical relationship between the second section 1564 and the second through hole 1542.

[0067] Among them, the above-mentioned transverse grooves and longitudinal grooves are two feasible implementation plans of the present application. In fact, the present application does not impose rigid restrictions on the groove directions of the first through hole 142 and the second through hole 1542. The length direction of the first through hole 142 and the second through hole 1542 can be 30°, 45° or 60° with the height direction of the first rib 140, as long as the second section 1564 is adjusted accordingly.

[0068] According to some embodiments of the present application, the first through hole 142 is filled with plastic.

[0069] In this embodiment, the first through hole 142 is filled with plastic, and the filled plastic can eliminate the hole structure on the first rib 140, and the plastic will not affect the normal transmission of electromagnetic waves. By filling the first through hole 142 with plastic, on the one hand, the first through hole 142 can be prevented from being directly exposed to the user's field of vision in the unfolded state, thereby improving the consistency of the exposed surface of the electronic device 100 and reducing the abruptness of the appearance of the electronic device 100. On the other hand, the filled plastic can block pollutants and prevent pollutants accumulated in the first through hole 142 from affecting the transmission effect of electromagnetic waves, thereby improving the communication reliability of the electronic device 100.

[0070] Following the above-mentioned embodiment, the operating frequency of the antenna assembly 150 can be controlled by the length of the second through hole 1542. Usually, the length of the second through hole 1542 is 1 / 2 of the operating wavelength, and the width of the second through hole 1542 can be adjusted according to the actual antenna impedance matching needs. At the same time, the length of the microstrip feed line 156 generally needs to exceed the center of the second through hole 1542, and the optimal length of the exceeding part is 1 / 4 of the operating wavelength to achieve the best radiation of electromagnetic energy. Usually, the width of the microstrip feed line 156 is the width of a 50-ohm microstrip line. Electromagnetic waves are emitted from the signal source, excite the second through hole 1542 through the microstrip feed line 156, and then radiate into the air through the first through hole 142 on the first rib 140 to achieve signal transmission and reception.

[0071] According to some embodiments of the present application, Figure 3 , Figure 4 and Figure 5 As shown, the electronic device 100 further includes: a shell assembly 180 including an opening, the first metal support 110, the second metal support 130, the antenna assembly 150 and the storage section 124 are all arranged in the shell assembly 180, and the unfolding section 122 is arranged in the opening.

[0072] In this embodiment, the electronic device 100 further includes a shell assembly 180, which is composed of a first shell 182, a second shell 184, and a back plate 186. The first shell 182 is a fixed shell, the first metal support 110 and the antenna assembly 150 are arranged in the first shell 182, the second shell 184 is a movable shell, the second metal support 130 is arranged in the second shell 184, and the second shell 184 and the second metal support 130 slide synchronously with the extension and retraction of the flexible screen 120. The back plate 186 is divided into two parts, one part of which 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 play a role in shielding the internal structure, and the front side opposite to the back plate 186 is the opening of the shell assembly 180, and the unfolded section 122 of the flexible screen 120 is embedded in the opening.

[0073] like Figure 3 , Figure 4 and Figure 5 As shown, when the electronic device 100 is in the storage 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, and the gap is aligned with the radiation port 172 surrounded by the first convex rib 140 and the second convex rib 170, so that electromagnetic waves can radiate outward through the radiation port 172 and the gap in sequence. Figure 8 , Fig. 9 and Fig.10 As shown, when the electronic device 100 switches to the unfolded state, the second shell 184 together with the back panel 186 thereon extends outward, and the first metal support member 110 between the two parts of the back panel 186 is exposed to the outside. For the antenna component 150, the clearance of the exposed area is better, and the antenna component 150 can directly radiate electromagnetic waves outward through the first through hole 142.

[0074] According to some embodiments of the present application, Figure 1 and Figure 6 As shown, the electronic device 100 further includes: a circuit board 190 , which is disposed in the shell assembly 180 and connected to the antenna assembly 150 .

[0075] In this embodiment, the electronic device 100 further includes a circuit board 190, which is disposed in the first housing 182, and the circuit board 190 is connected to the first metal support 110 via the antenna assembly 150. On the one hand, the circuit board 190 is used as a signal source of the antenna assembly 150, and during operation, the circuit board 190 radiates electromagnetic energy to the external environment via the antenna assembly 150 to achieve signal reception and transmission. 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 achieve automatic unfolding and automatic storage of the electronic device 100, thereby eliminating the manual push-pull operation mode of the user.

[0076] According to some embodiments of the present application, Figure 1 and Figure 6 As shown, the unfolding section 122 is connected to the shell assembly 180, and the storage section 124 is connected to the second metal support 130. The electronic device 100 also includes: a roller 188, which is connected to the second metal support 130, and the storage section 124 is wound around the second side of the first metal support 110 via the roller 188; a driving assembly 189, which is arranged on the first metal support 110 and connected to the second metal support 130, and is used to drive the second metal support 130 to reciprocate along the first direction.

[0077] In this embodiment, the unfolding section 122 of the flexible screen 120 is fixed on the shell assembly 180, specifically connected to the first shell 182, and the storage section 124 is connected to the movable second metal support 130. On this basis, the electronic device 100 also includes a roller 188 and a drive assembly 189, the roller 188 is rotatably connected to the second metal support 130, and the unfolding section 122 is wound around the peripheral side of the roller 188 to the second metal support 130 located on the second side of the first metal support 110. The drive assembly 189 is connected to the first metal support 110, and the drive assembly 189 is used to drive the second metal support 130 to slide relative to the first metal support 110. Specifically, a motor hinge structure can be selected as the drive assembly 189, and an electric telescopic cylinder and other mechanisms can also be selected to achieve drive. For this embodiment, no rigid limitation is made on the specific structural form of the drive assembly 189.

[0078] When the user needs to increase the display size, the driving component 189 drives the second metal support member 130130 to move relative to the first metal support member 110 along the first direction (eg Figure 1 During this process, the second metal support 130 and the roller 188 push the transition area between the unfolding section 122 and the storage section 124 to increase the length of the unfolding section 122 and shorten the length of the storage section 124. Accordingly, when the user does not need to use the large-size screen, the driving component 189 drives the second metal support 130 and the roller 188 to move in a second direction (eg, Figure 6 During the process, the flexible screen 120 is pulled to increase the length of the storage section 124 and reduce the length of the unfolded section 122, so as to reduce the size of the electronic device 100 and reduce the difficulty of holding and storing.

[0079] At the same time, in the process of adjusting the display size of the flexible screen 120, the roller 188 rotates to ensure the smoothness of the rolling or unfolding movement of the flexible screen 120, thereby preventing the flexible screen 120 from getting stuck. In addition, the first metal support 110, the second metal support 130 and the roller 188 can provide effective support for the flexible screen 120, thereby ensuring that the flexible screen 120 is always in a tensioned state, thereby preventing the flexible screen 120 from being uneven.
