[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 fixed bracket 110, including a first through hole 112; 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 fixed bracket 110, and the storage section 124 is wound from the first side of the fixed bracket 110 to the second side of the fixed bracket 110; a sliding bracket 130, which is arranged between the storage section 124 and the fixed bracket 110, and is spaced from the storage section 124 and the fixed bracket 110, and the sliding bracket 130 can slide with the storage section 124, and the sliding bracket 130 includes a second through hole 132 and a third through hole 134; a feeding component 140, which is connected to the fixed bracket 110 and is arranged opposite to the first through hole 112; a first conductive portion 180, which is arranged on the sliding bracket 130, contacts the storage section 124, and is located between the second through hole 132 and the third through hole 134;

[0031] The sliding bracket 130 has a first position and a second position relative to the fixed bracket 110; when the sliding bracket 130 is in the first position, the first through hole 112 is opposite to the second through hole 132, the sliding bracket 130, the first conductive portion 180 and the receiving section 124 enclose a first resonant cavity 1322, and the feeding component 140 excites the first resonant cavity 1322 to resonate; when the sliding bracket 130 is in the second position, the first through hole 112 is opposite to the third through hole 134, the third through hole 134, the fixed bracket 110, the sliding bracket 130, the first conductive portion 180 and the receiving section 124 enclose a second resonant cavity 1342, and the feeding component 140 excites the second resonant cavity 1342 to resonate.

[0032] In the embodiment of the present application, the electronic device 100 includes a fixed bracket 110, a sliding bracket 130 and a flexible screen 120. The fixed bracket 110 is a main frame structure in the electronic device 100, which is used to position and support other structures on the electronic device 100. The sliding bracket 130 is arranged opposite to the fixed bracket 110, and the sliding bracket 130 can slide relative to the fixed bracket 110.

[0033] According to the distribution position, the flexible screen 120 is divided into an unfolding section 122 and a storage section 124. The unfolding section 122 is an exposed part, which is used to obtain information on the unfolding section 122 and interact through touch operation, that is, the size of the screen that the user can use is directly related to the length of the unfolding section 122. The storage section 124 is hidden inside the electronic device 100 for adjusting the screen size. Among them, the unfolding section 122 is set on the fixed bracket 110, and is positioned and supported by the fixed bracket 110. The storage section 124 is set on the sliding bracket 130, and is positioned and supported by the sliding bracket 130.

[0034] When the user needs to increase the display size, the motor hinge structure drives the sliding bracket 130 to slide relative to the fixed bracket 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 sliding bracket 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.

[0035] Furthermore, a first through hole 112 is provided on the fixing bracket 110, the feeding assembly 140 is connected to the fixing bracket 110, and the transmitting end of the feeding assembly 140 is arranged opposite to the first through hole 112, so as to radiate electromagnetic waves to the outside of the electronic device 100 by means of the first through hole 112. By arranging the feeding assembly 140 on the fixing bracket 110 and radiating electromagnetic waves by means of the inherent structure on the fixing bracket 110, the telescopic side of the flexible screen 120 and the motor hinge structure that drives the flexible screen 120 to move can be avoided, so as to prevent the telescopic side and the motor hinge structure from affecting the operation of the feeding assembly 140.

[0036] On this basis, the first side of the sliding bracket 130 is spaced from the storage section 124, the second side of the sliding bracket 130 is spaced from the fixed bracket 110, and the sliding bracket 130 is provided with a second through hole 132 and a third through hole 134 that longitudinally penetrate the sliding bracket 130, the second through hole 132 and the third through hole 134 are staggered on the sliding bracket 130, and the relative positions of the second through hole 132 and the third through hole 134 and the fixed bracket 110 change during the movement of the sliding bracket 130 relative to the fixed bracket 110. The sliding bracket 130 is also provided with a first conductive portion 180, the first conductive portion 180 is in contact with the lower surface of the storage section 124, and the first conductive portion 180 is located between the second through hole 132 and the third through hole 134, and the first conductive portion 180 can block the transmission of electromagnetic waves between the second through hole 132 and the third through hole 134.

[0037] The sliding bracket 130 has a first position and a second position relative to the fixed bracket 110 , the first position corresponds to the unfolded state of the electronic device 100 , and the second position corresponds to the stored state of the electronic device 100 .

[0038] like Figure 1 and Figure 2 As shown, when the sliding bracket 130 is in the first position, the sliding bracket 130 and the fixed bracket 110 are unfolded, the second through hole 132 on the sliding bracket 130 is opposite to the first through hole 112 on the fixed bracket 110, and the third through hole 134 is staggered from the first through hole 112, so that the sliding bracket 130, the first conductive portion 180, and the receiving section 124 enclose a first resonant cavity 1322 ( Figure 1 The dotted box in the middle shows the position of the first resonant cavity 1322). In this state, the feeding assembly 140 is used as a coupling feeding structure of the first resonant cavity 1322, and the electromagnetic wave radiated through the first through hole 112 excites the resonance of the first resonant cavity 1322, so that the electromagnetic wave is radiated outward through the first resonant cavity 1322 after the resonance obtains the required frequency.

[0039] in, Figure 1 and Figure 2 The middle arrow a shows the radiation area of ​​the electromagnetic wave in the unfolded state.

[0040] like Figure 6 and Figure 7 As shown, when the sliding bracket 130 slides to the second position along the second direction, the sliding bracket 130 and the fixed bracket 110 are closed, the third through hole 134 on the sliding bracket 130 slides to a position opposite to the first through hole 112, and the second through hole 132 slides to a position staggered from the first through hole 112. The third through hole 134, the fixed bracket 110, the sliding bracket 130, the first conductive portion 180 and the receiving section 124 together enclose a second resonant cavity 1342 ( Figure 6The dotted box in the middle shows the position of the second resonant cavity 1342). In this state, the feeding component 140 is used as a coupling feeding structure of the second resonant cavity 1342, and the electromagnetic wave radiated through the first through hole 112 excites the resonance of the second resonant cavity 1342, so that the electromagnetic wave is radiated outward through the second resonant cavity 1342 after the resonance obtains the required frequency.

[0041] in, Figure 6 and Figure 7 The middle arrow b shows the radiation area of ​​the electromagnetic wave in the unfolded state. Figure 1 The arrow d shows the first direction, and the arrow c shows the second direction.

[0042] Among them, the shapes and sizes of the second through hole 132 and the third through hole 134 can be adjusted according to the radiation requirements of the electronic device 100 in different states. For example, by setting the second through hole 132 and the third through hole 134 with the same shape and size, the electronic device 100 can have basically the same radiation performance in the unfolded state and the stored state, so as to avoid the unfolding and storage actions of the flexible screen 120 affecting the communication capability of the electronic device 100.

[0043] It can be seen that the present application introduces the above-mentioned structural layout, so that the feeding assembly 140 can excite different resonant cavities respectively when the sliding bracket 130 is in different positions. Specifically, the first resonant cavity 1322 is used for radiation in the first position, and the second resonant cavity 1342 is used for resonant radiation in the second position, so that the electronic device 100 can maintain good radiation performance in different flexible screen 120 states, eliminate the adverse effects of the linkage structure of the flexible screen 120 on the feeding assembly 140, and solve the technical problem of poor communication performance of the electronic device 100 in a specific flexible screen 120 state.

[0044] Furthermore, in this embodiment, there is no rigid limitation on the type of the feeding component 140. The feeding component 140 can be a slot antenna in the following embodiment, or a monopole antenna, a vibrator antenna or a helical antenna can be selected as the feeding component 140, which can specifically meet the requirements of electromagnetic wave transmission and resonant cavity excitation.

[0045] Specifically, conductive foam can be selected as the first conductive part 180, and metal springs can also be selected as the first conductive part 180. In this regard, the technical solution does not impose a rigid restriction on the material and structure of the first conductive part 180, and only needs to meet the grounding requirement.

[0046] Specifically, the electronic device 100 further includes a second conductive portion 182 and a third conductive portion 184, wherein the second conductive portion 182 is disposed between the sliding bracket 130 and the storage section 124, and transitionally connects the sliding bracket 130 and the storage section 124, and the second conductive portion 182 is used to cooperate with the first conductive portion 180, the storage section 124, and the sliding bracket 130 to enclose a portion of the second resonant cavity 1342, so as to prevent electromagnetic waves from leaking from the right side of the sliding bracket 130. Similarly, the third conductive portion 184 is disposed at the right end of the fixed bracket 110, and the third conductive portion 184 contacts the sliding bracket 130, and the third conductive portion 184 cooperates with the fixed bracket 110 and the sliding bracket 130 to enclose a portion of the first resonant cavity 1322, so as to prevent electromagnetic waves from leaking from the right side of the fixed bracket 110.

[0047] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, the electronic device 100 further includes: a first rib 136 disposed on the sliding bracket 130 and opposite to the end of the storage section 124 ; a first radiation port 1362 communicating with the first resonant cavity 1322 is formed between the first rib 136 and the storage section 124 .

[0048] In this embodiment, the sliding bracket 130 is provided with a first rib 136, the first rib 136 is away from the fixed bracket 110, and the first rib 136 is opposite to the section of the storage section 124 in the first direction. The first rib 136 is arranged at intervals with the end of the storage section 124, so as to enclose a first radiation port 1362 between the first rib 136 and the storage section 124, which communicates with the space between the storage section 124 and the sliding bracket 130. At the same time, in the first direction, the second through hole 132 is located between the first rib 136 and the third through hole 134. When the sliding bracket 130 is located in the first position, the first through hole 112 is opposite to the first resonant cavity 1322, and the electromagnetic wave radiated from the first through hole 112 successfully excites the first resonant cavity 1322. After the electromagnetic wave resonates through the first resonant cavity 1322, it is radiated to the outside of the electronic device 100 through the first radiation port 1362 close to the first resonant cavity 1322.

[0049] It can be seen that by setting the first rib 136, a first radiation port 1362 capable of directionally radiating electromagnetic waves can be constructed between the flexible screen 120 and the sliding bracket 130, so that the electromagnetic waves are guided to the desired area through the first radiation port 1362, thereby improving the communication performance of the electronic device 100.

[0050] Specifically, Figure 1 and Figure 2As shown, the electromagnetic waves radiated through the first radiation port 1362 cover area a, and area a is only used to install the back plate 156 of the electronic device 100, which has little interference on the transmission of electromagnetic waves, which is beneficial to improving the communication effect of the electronic device 100.

[0051] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, the first radiation opening 1362 faces the third direction, and the first radiation opening 1362 gradually increases in the radiation direction.

[0052] In this embodiment, the first radiation port 1362 faces the third direction, that is, the back side direction of the electronic device 100. In the radiation direction, the size of the first radiation port 1362 gradually increases to form a trumpet-shaped first radiation port 1362. Specifically, a first inclined surface can be provided on the first rib 136, the first inclined surface is opposite to the end of the storage section 124, and the first inclined surface is inclined in a direction away from the storage section 124.

[0053] By providing the trumpet-shaped first radiation port 1362 , 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] According to some embodiments of the present application, Figure 6 and Figure 7 As shown, the sliding bracket 130 and the fixed bracket 110 are spaced apart, and the electronic device 100 also includes: a second convex rib 114, which is arranged on the fixed bracket 110 and is opposite to the first convex rib 136; when the sliding bracket 130 is in the second position, a second radiation port 1142 of the second resonant cavity 1342 is formed between the first convex rib 136 and the second convex rib 114.

[0055] In this embodiment, the fixed bracket 110 is provided with a second rib 114 , which is opposite to the first rib 136 in the first direction, and the first rib 136 gradually approaches the second rib 114 when the sliding bracket 130 moves from the first position to the second position.

[0056] When the sliding bracket 130 moves to the second position, the first convex rib 136 and the second convex rib 114 enclose a second radiation port 1142 of the second resonant cavity 1342. In addition, in this state, the first through hole 112 is opposite to the second resonant cavity 1342, and the electromagnetic wave can successfully excite the second resonant cavity 1342. At the same time, the first through hole 112 and the second through hole 132 are staggered, and the first resonant cavity 1322 loses its resonance effect. The electromagnetic wave resonated by the second resonant cavity 1342 is finally radiated to the outside of the electronic device 100 through the second radiation port 1142.

[0057] It can be seen that by setting the second rib 114, a second radiation port 1142 different from the first radiation port 1362 is formed in the electronic device 100, so that the first resonant cavity 1322 and the second resonant cavity 1342 can radiate electromagnetic waves outward through different paths respectively, so as to reduce the influence of the movement of the sliding bracket 130 on the electromagnetic wave transmission process, and ensure that the electronic device 100 has excellent electromagnetic wave radiation characteristics in different states.

[0058] According to some embodiments of the present application, Figure 6 and Figure 7 As shown, the second radiation opening 1142 faces the third direction, and the second radiation opening 1142 gradually increases in radiation.

[0059] In this embodiment, the second radiation port 1142 is also facing the third direction. By setting the first radiation port 1362 and the second radiation port 1142 with the same direction, the electronic device 100 can radiate electromagnetic waves in the same direction and the same area in both the unfolded state and the stored state, thereby eliminating the influence of the position switching of the sliding bracket 130 on the radiation direction and the radiation area, and thus achieving the technical effect of improving the communication stability of the electronic device 100.

[0060] Furthermore, in the radiation direction, the size of the second radiation opening 1142 gradually increases to form a trumpet-shaped second radiation opening 1142. Specifically, a second inclined plane can be provided on the first convex rib 136, and a third inclined plane can be provided on the second convex rib 114, and the second inclined plane and the third inclined plane are symmetrically provided to form a trumpet-shaped second radiation opening 1142.

[0061] By providing the trumpet-shaped second radiation port 1142 , 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.

[0062] According to some embodiments of the present application, Figure 2 , Figure 7 and Fig.11 As shown, the feeding assembly 140 includes: a dielectric layer 142; a metal layer 144, which is arranged on the dielectric layer 142 and includes a fourth through hole 1442, and the fourth through hole 1442 is connected to the second end of the first through hole 112; a feed line 146, which is arranged on the dielectric layer 142 and away from the metal layer 144; the feed line 146 includes a first section 1462 and a second section 1464, the first section 1462 is used to connect to the signal source, and the second section 1464 is arranged opposite to the fourth through hole 1442.

[0063] In this embodiment, the structure of the feeding assembly 140 is described. Specifically, the feeding assembly 140 includes a dielectric layer 142, a metal layer 144 and a feed line 146. Different structures are made on both sides of the dielectric layer 142, a microstrip line is made in the lower layer as the feed line 146, and a metal is made in the upper layer as the metal ground of the feed line 146. On this basis, a fourth through hole 1442 is opened on the metal layer 144 to construct the feeding assembly 140 as a slot antenna. Among them, the microstrip feed line 146 is divided into a first section 1462 and a second section 1464, the first section 1462 is used to connect the signal source to obtain electromagnetic energy from the signal source, the second section 1464 is closely attached to the dielectric layer 142, and the second section 1464 is arranged opposite to the fourth through hole 1442 on the metal layer 144, so that the electromagnetic energy can be radiated outward through the fourth through hole 1442.

[0064] During the assembly process, the metal layer 144 of the feeding assembly 140 is attached to the first rib 136 , and the fourth through hole 1442 is aligned with the first through hole 112 , ensuring that the electromagnetic waves output by the slot antenna can be radiated outward through the first through hole 112 .

[0065] By constructing the feeding assembly 140 as a slot antenna, the feeding assembly 140 itself can be used as an antenna and also as a slot coupling feeding structure, thereby improving the feeding effect of the feeding assembly 140 on the resonant cavity in the stored state.

[0066] According to some embodiments of the present application, Figure 7 and Fig.12 As shown, the cross-sections of the first through hole 112 and the fourth through hole 1442 are both rectangular; the cross-section size of the first through hole 112 is greater than or equal to the cross-section size of the fourth through hole 1442 .

[0067] In this embodiment, the first through hole 112 and the fourth through hole 1442 are both rectangular holes, and the cross-sectional size of the first through hole 112 is greater than or equal to the cross-sectional size of the fourth through hole 1442. By configuring the first through hole 112 and the fourth through hole 1442 as elongated rectangular holes, the transmission effect of electromagnetic waves can be improved to improve the radiation performance of the feeding assembly 140. By setting the first through hole 112 to have a size greater than or equal to the fourth through hole 1442, it can be ensured that the first through hole 112 will not block the electromagnetic waves output by the feeding assembly 140, so as to ensure that the feeding assembly 140 can obtain good antenna radiation performance.

[0068] According to some embodiments of the present application, Figure 7 and Fig.12 As shown, the length direction of the second section 1464 is perpendicular to the length direction of the fourth through hole 1442 .

[0069] In this embodiment, the second section 1464 attached to the dielectric layer 142 is vertically disposed to the elongated fourth through hole 1442 to ensure that the feeding assembly 140 can obtain excellent radiation performance.

[0070] Specifically, Figure 7 As shown, when the length direction of the first through hole 112 and the fourth through hole 1442 is perpendicular to the height direction of the first rib 136, the extension direction of the second section 1464 and the first section 1462 is consistent with the length direction of the dielectric layer 142. Fig.12 As shown, when the length directions of the first through hole 112 and the fourth through hole 1442 are consistent with the height direction of the first rib 136 , the second section 1464 is bent 90° relative to the first section 1462 to ensure the vertical relationship between the second section 1464 and the fourth through hole 1442 .

[0071] Among them, the above-mentioned transverse grooves and longitudinal grooves are two feasible implementation schemes of the present application. In fact, the present application does not impose a rigid restriction on the groove directions of the first through hole 112 and the fourth through hole 1442. The length direction of the first through hole 112 and the fourth through hole 1442 can be 30°, 45° or 60° with the height direction of the first rib 136, as long as the second section 1464 is adjusted accordingly.

[0072] Following the above-mentioned embodiment, the operating frequency of the feeding assembly 140 can be controlled by the length of the fourth through hole 1442. Usually, the length of the fourth through hole 1442 is 1 / 2 of the working wavelength, and the width of the fourth through hole 1442 can be adjusted according to the actual antenna impedance matching needs. At the same time, the length of the microstrip feed line 146 generally needs to exceed the center of the fourth through hole 1442, and the optimal length of the exceeding part is 1 / 4 of the working wavelength to achieve the best radiation of electromagnetic energy. Usually, the width of the microstrip feed line 146 is the width of a 50-ohm microstrip line. The electromagnetic wave excites the fourth through hole 1442 through the microstrip feed line 146, and then radiates into the air through the first through hole 112 on the first rib 136 to achieve signal transmission and reception.

[0073] According to some embodiments of the present application, the fixed bracket 110 is made of metal, the sliding bracket 130 is made of metal, and the electronic device 100 further includes: a first plastic part 170 embedded in the second through hole 132; and a second plastic part 172 embedded in the third through hole 134.

[0074] In this embodiment, the fixed bracket 110 is a metal bracket, and the sliding bracket 130 is also a metal bracket. By ensuring that the material of the fixed bracket 110 and the sliding bracket 130 is a metal material, it can be ensured that the second resonant cavity 1342 that limits the transmission direction of the electromagnetic wave can be enclosed between the fixed bracket 110 and the sliding bracket 130, and it can be ensured that the metal plate in the sliding bracket 130 and the flexible screen 120 can enclose the first resonant cavity 1322 that limits the transmission direction of the electromagnetic wave. On this basis, the second through hole 132 is filled with a first plastic, and the first plastic part 170 can eliminate the hole structure on the sliding bracket 130, and the plastic will not affect the normal transmission of the electromagnetic wave. By filling the second through hole 132 with plastic, it can play a role in blocking pollutants, avoiding the pollutants accumulated in the second through hole 132 from affecting the transmission effect of the electromagnetic wave, thereby improving the communication reliability of the electronic device 100.

[0075] Similarly, the third through hole 134 is filled with the second plastic member 172 , and the second plastic member 172 can eliminate the hole structure on the sliding bracket 130 to prevent pollutants from accumulating in the third through hole 134 without affecting the transmission of electromagnetic waves.

[0076] 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 150 including an opening 151 , the fixed bracket 110 , the sliding bracket 130 , the feeding assembly 140 and the storage section 124 are all disposed in the shell assembly 150 , and the unfolding section 122 is disposed in the opening 151 .

[0077] In this embodiment, the electronic device 100 further includes a shell assembly 150, which is composed of a first shell 152, a second shell 154 and a back plate 156. The first shell 152 is a fixed shell, the fixed bracket 110 and the feeding assembly 140 are arranged in the first shell 152, the second shell 154 is a movable shell, the sliding bracket 130 is arranged in the second shell 154, and the second shell 154 and the sliding bracket 130 slide synchronously with the extension and retraction of the flexible screen 120. The back plate 156 is divided into two parts, one part of which is fixed on the back side of the first shell 152, and the other part is fixed on the back side of the second shell 154, so as to play a role in shielding the internal structure. The front side opposite to the back plate 156 is the opening 151 of the shell assembly 150, and the unfolded section 122 of the flexible screen 120 is embedded in the opening 151.

[0078] like Figure 3 , Figure 4 and Figure 5As shown, when the electronic device 100 is in the storage state, the first shell 152 and the second shell 154 are close to each other, and a gap is left between the two back plates 156, and the gap is aligned with the radiation port enclosed by the first rib 136 and the second rib 114, so that electromagnetic waves can radiate outward through the radiation port 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 154 and the back panel 156 thereon extend outward, and the fixing bracket 110 between the two parts of the back panel 156 is exposed to the outside. For the feeding component 140, the clearance of the exposed area is better, and the feeding component 140 can directly radiate electromagnetic waves outward through the first through hole 112.

[0079] According to some embodiments of the present application, Figure 1 and Figure 6 As shown, the electronic device 100 further includes: a circuit board 160 , which is disposed in the shell assembly 150 and connected to the feeding assembly 140 .

[0080] In this embodiment, the electronic device 100 further includes a circuit board 160, which is disposed in the first housing 152, and the circuit board 160 is connected to the fixed bracket 110 through the feeding assembly 140. On the one hand, the circuit board 160 is used as a signal source of the feeding assembly 140. During operation, the circuit board 160 radiates electromagnetic energy to the external environment through the feeding assembly 140 to achieve signal reception and transmission. The circuit board 160 is also used as a control structure of the electronic device 100. The control circuit thereon can control the motor hinge structure to drive the second housing 154 and the sliding bracket 130 to slide according to the expansion instruction and the storage instruction, so as to achieve automatic expansion and automatic storage of the electronic device 100, thereby eliminating the manual push-pull operation mode of the user.

[0081] 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 150, and the storage section 124 is connected to the sliding bracket 130. The electronic device 100 also includes: a roller 158, which is connected to the sliding bracket 130, and the storage section 124 is wound around to the second side of the fixed bracket 110 via the roller 158; a driving assembly 159, which is arranged on the fixed bracket 110 and connected to the sliding bracket 130, and is used to drive the sliding bracket 130 to reciprocate along the first direction.

[0082] In this embodiment, the unfolding section 122 of the flexible screen 120 is fixed on the shell assembly 150, specifically connected to the first shell 152, and the storage section 124 is connected to the movable sliding bracket 130. On this basis, the electronic device 100 also includes a roller 158 and a driving assembly 159, the roller 158 is rotatably connected to the sliding bracket 130, and the unfolding section 122 is wound around the peripheral side of the roller 158 to the sliding bracket 130 located on the second side of the fixed bracket 110. The driving assembly 159 is connected to the fixed bracket 110, and the driving assembly 159 is used to drive the sliding bracket 130 to slide relative to the fixed bracket 110. Specifically, a motor hinge structure can be selected as the driving assembly 159, and an electric telescopic cylinder and other mechanisms can also be selected to realize the drive. For this embodiment, no rigid limitation is made on the specific structural form of the driving assembly 159.

[0083] When the user needs to increase the display size, the driving assembly 159 drives the sliding bracket 130 to move relative to the fixed bracket 110 along a first direction (eg, Figure 1 During this process, the sliding bracket 130 and the roller 158 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. Correspondingly, when the user does not need to use the large-size screen, the driving component 159 drives the sliding bracket 130 and the roller 158 to move in a second direction (eg, Figure 1 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.

[0084] At the same time, in the process of adjusting the display size of the flexible screen 120, the roller 158 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 fixed bracket 110, the sliding bracket 130 and the roller 158 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.
