[0030] Combine the following Figures 1 to 14 An electronic device according to an embodiment of the present application is described.

[0031] like Figure 1 and Figure 7 As shown, in some embodiments of the present application, an electronic device 100 is provided, and the electronic device 100 includes: a flexible screen 120, including an unfolding section 122 and a storage section 124; a fixed bracket 110, used to support the unfolding section 122, and the fixed bracket 110 includes a first through hole 112, used to support the unfolding section 122; a sliding bracket 130, which is arranged opposite to the fixed bracket 110 and is spaced from the fixed bracket 110, and is used to support the storage section 124, and the sliding bracket 130 can reciprocate along the first direction with the storage section 124;

[0032] 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, a first resonant cavity 136 is enclosed between the sliding bracket 130 and the fixed bracket 110, the first through hole 112 is opposite to the first resonant cavity 136, and the feeding component 160 excites the first resonant cavity 136 to resonate; when the sliding bracket 130 is in the second position, a first resonant cavity 136 and a second resonant cavity 137 are enclosed between the sliding bracket 130 and the fixed bracket 110, the first resonant cavity 136 and the second resonant cavity 137 are connected, and the first through hole 112 is opposite to the second resonant cavity 137, and the feeding component 160 excites the first resonant cavity 136 and the second resonant cavity 137 to resonate.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] in, Figure 1 The arrow e shows the first direction, and the arrow f shows the second direction.

[0037] Furthermore, a first through hole 112 is provided on the fixing bracket 110, the feeding assembly 160 is connected to the fixing bracket 110, and the transmitting end of the feeding assembly 160 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 160 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 160.

[0038] On this basis, the sliding bracket 130 is spaced apart from the fixed bracket 110 , and 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 .

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, when the sliding bracket 130 is in the first position, the sliding bracket 130 and the fixed bracket 110 are unfolded, the first through hole 112 is opposite to the first area on the sliding bracket 130, and the first area and the fixed bracket 110 enclose a first resonant cavity 136. In this state, the feeding assembly 160 is used as a coupling feeding structure of the first resonant cavity 136, and the electromagnetic wave radiated through the first through hole 112 excites the resonance of the first resonant cavity 136, so that the electromagnetic wave is radiated outward through the first resonant cavity 136 after the resonance obtains the required frequency. Figure 1 and Figure 2 The middle arrow a shows the radiation area of ​​the electromagnetic wave in the unfolded state.

[0040] like Figure 7 , Figure 8 and Fig. 9 As shown, when the sliding bracket 130 slides to the second position along the second direction, the sliding bracket 130 is closed with the fixed bracket 110, and the first area on the sliding bracket 130 is staggered with the first through hole 112, that is, the first resonant cavity 136 slides synchronously in the second direction, and the first through hole 112 is opposite to the second area on the sliding bracket 130, and at this time, the second area and the fixed bracket 110 also enclose a second resonant cavity 137 connected to the first resonant cavity 136. In this state, the feeding component 160 is used as a coupling feeding structure of the first resonant cavity 136 and the second resonant cavity 137, and the electromagnetic waves radiated through the first through hole 112 excite the resonance of the first resonant cavity 136 and the second resonant cavity 137, so that the electromagnetic waves are radiated outward through the first resonant cavity 136 and the second resonant cavity 137 after the resonance obtains the required frequency. Among them, Figure 7 and Figure 8 The middle arrow b shows the radiation area of ​​the electromagnetic wave in the unfolded state.

[0041] Among them, the shape and size of the first resonant cavity 136 and the second resonant cavity 137 can be adjusted according to the radiation requirements of the electronic device 100 in different states. For example, by setting the first resonant cavity 136 and the second resonant cavity 137 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.

[0042] It can be seen that the present application introduces the above-mentioned structural layout, so that the feeding assembly 160 can excite different resonant cavities when the sliding bracket 130 is in different positions. Specifically, the first resonant cavity 136 is used for radiation in the first position, and the first resonant cavity 136 and the second resonant cavity 137 are 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 160, and solve the technical problem of poor communication performance of the electronic device 100 in a specific flexible screen 120 state.

[0043] Furthermore, in this embodiment, there is no rigid limitation on the type of the feeding component 160. The feeding component 160 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 feeding component 160, which can specifically meet the requirements of electromagnetic wave transmission and resonant cavity excitation.

[0044] According to some embodiments of the present application, Figure 3 and Fig. 9 As shown, the electronic device 100 also includes: a first conductive portion 140, which is arranged on the fixed bracket 110; wherein, when the sliding bracket 130 is in the first position, the first conductive portion 140 contacts the first area on the sliding bracket 130, and the fixed bracket 110, the sliding bracket 130 and the first conductive portion 140 enclose a first resonant cavity 136; the first area is located between the first resonant cavity 136 and the second resonant cavity 137; when the sliding bracket 130 is in the second position, the first conductive portion 140 contacts the second area on the sliding bracket 130, and the fixed bracket 110, the sliding bracket 130 and the first conductive portion 140 enclose a first resonant cavity 136 and a second resonant cavity 137.

[0045] In this embodiment, a conductive portion is disposed on the fixed bracket 110 , and the conductive portion is located between the fixed bracket 110 and the sliding bracket 130 . During the sliding process of the sliding bracket 130 , the relative position of the conductive portion on the sliding bracket 130 changes.

[0046] Specifically, when the sliding bracket 130 is located at the first position, the conductive part abuts against the first area on the sliding bracket 130, serving as a metal ground connecting the fixed bracket 110 and the sliding bracket 130, wherein the first area is between the first resonant cavity 136 and the second resonant cavity 137 in the first direction, and the conductive part separates the first resonant cavity 136 and the second resonant cavity 137 to prevent electromagnetic waves from being transmitted in the direction of the second resonant cavity 137.

[0047] When the sliding bracket 130 slides along the second direction to the second position, the relative position of the conductive part on the sliding bracket 130 moves toward the direction of the second resonant cavity 137 until the conductive part abuts against the second region on the sliding bracket 130. In this state, the first resonant cavity 136 and the second resonant cavity 137 are located on the same side of the second region, so that the electromagnetic wave radiated by the first through hole 112 is transmitted in the direction of the first resonant cavity 136 after passing through the resonance of the second resonant cavity 137.

[0048] It can be seen that, by providing the conductive part, on the one hand, it can play a role in limiting the transmission route of the electromagnetic wave, so as to ensure that the electromagnetic wave can be radiated out of the electronic device 100 in a predetermined direction. On the other hand, the resonant frequency of the resonant cavity can be adjusted by limiting the length of the resonant cavity, so that the electromagnetic wave radiated through the first through hole 112 is converted into an electromagnetic wave with a required frequency after the resonance of the resonant cavity, so as to ensure that the electromagnetic wave finally radiated out of the electronic device 100 can meet the communication requirements. In this way, the technical effect of improving the communication effect of the electronic device 100 and optimizing the user experience of the electronic device 100 is achieved.

[0049] Specifically, the position of the conductive part can be adjusted according to the required resonant frequency. There are multiple conductive parts, and the multiple conductive parts are spaced apart on a straight line perpendicular to the first direction. Specifically, two spaced conductive parts can be set to further improve the resonance accuracy of the resonant cavity and improve communication reliability.

[0050] According to some embodiments of the present application, Figure 3 and Fig. 9 As shown, the electronic device 100 also includes: a first boss 150, which is arranged on the sliding bracket 130, and the end surface of the first boss 150 forms a first area; a second boss 152, which is arranged on the sliding bracket 130, and in the first direction, the first boss and the second boss are spaced apart, and the end surface of the second boss 152 forms a second area.

[0051] In this embodiment, a first boss 150 is formed between the first resonant cavity 136 and the second resonant cavity 137, and the end surface of the first boss 150 forms the aforementioned first region, which serves as the first grounding point of the sliding bracket 130. A second boss 152 is further provided on the opposite side of the first boss 150 relative to the second resonant cavity 137, and the end surface of the second boss 152 forms the aforementioned second region, which serves as the second grounding point of the sliding bracket 130.

[0052] When the sliding bracket 130 is in the first position, the first grounding point is connected, the second grounding point is disconnected, and the electromagnetic waves radiated through the first through hole 112 are directly radiated to the outside of the electronic device 100 after resonating through the first resonant cavity 136. When the sliding bracket 130 is in the second position, the first grounding point is disconnected, the second grounding point is connected, the first resonant cavity 136 and the second resonant cavity 137 are connected, and the feeding component excites the first resonant cavity 136 and the second resonant cavity 137. At this time, the electromagnetic waves resonated through the first resonant cavity 136 and the second resonant cavity 137 are radiated to the outside of the electronic device 100.

[0053] It can be seen that by providing the first boss 150 and the second boss 152, the working areas of the first resonant cavity 136 and the second resonant cavity 137 can be precisely divided in cooperation with the conductive part, and the working states of the two resonant cavities can be adjusted by controlling the connection relationship of the conductive part. Thus, the radiation mode of the electronic device 100 can be switched synchronously with the sliding action of the sliding component, ensuring that the electronic device 100 has excellent radiation performance in both the unfolded state and the stored state.

[0054] According to some embodiments of the present application, Figure 3 and Fig. 9 As shown, the electronic device 100 further includes: a third boss 154 disposed on the fixing bracket 110 , and the first conductive portion 140 is connected to the third boss 154 .

[0055] In this embodiment, the fixed bracket 110 is further provided with a third boss 154, the third boss 154 protrudes toward the direction where the sliding bracket 130 is located, and the conductive portion is provided on the end surface of the third boss 154. When the sliding bracket 130 is located at the first position, the first boss 150, the conductive portion and the third boss 154 are combined into a first grounding structure, and when the sliding bracket 130 is located at the second position, the second boss 152, the conductive portion and the third boss 154 are combined into a stacked grounding structure.

[0056] By providing the third boss 154, on the one hand, the depth of the first resonant cavity 136 and the second resonant cavity 137 can be increased in cooperation with the first boss 150 and the second boss 152, so as to ensure that the inherent structural properties of the resonant cavity can match the communication requirements of the electronic device 100. On the other hand, by providing the third boss 154, on the one hand, the impedance characteristics of the electronic device 100 can be adjusted in cooperation with the first boss 150 and the second boss 152, so as to obtain a better electromagnetic wave radiation effect, thereby achieving the technical effect of improving the communication performance of the electronic device 100.

[0057] In this embodiment, the fixed bracket 110 is provided with a first convex rib 116, and the first convex rib 116 is provided with a second through hole 1162 that runs transversely therethrough. In the first direction, the first convex rib 116 is arranged opposite to the first end of the sliding bracket 130, and the first end is away from the first convex rib 116 during the sliding process of the sliding bracket 130 from the second position to the first position.

[0058] Specifically, when the sliding bracket 130 is in the first position, the flexible screen 120 is in the unfolded state, and the first end of the sliding bracket 130 is away from the first convex rib 116. In this case, the electromagnetic wave resonated by the first resonant cavity 136 is radiated from the gap between the first end of the sliding bracket 130 and the fixed bracket 110 to the third direction, and because the first convex rib 116 is far away from the gap, it will not interfere with the radiation of the electromagnetic wave.

[0059] When the sliding bracket 130 is in the second position, the flexible screen 120 is in the storage state, and the first end of the sliding bracket 130 is close to the first convex rib 116. In this case, the electromagnetic wave resonated by the second resonant cavity 137 is radiated from the gap between the first end of the sliding bracket 130 and the fixed bracket 110 to the first convex rib 116, and is radiated to the outside of the electronic device 100 under the guidance of the second through hole 1162.

[0060] It can be seen that by providing the first rib 116 and the second through hole 1162, the radiation direction of the electromagnetic wave can be adjusted when the electronic device 100 is in the storage state. Specifically, the direction of the second through hole 1162 can be adjusted so that the electronic device 100 can radiate electromagnetic waves in the same direction and the same area in both the unfolded state and the storage state, thereby eliminating the influence of the position switching of the sliding bracket 130 on the radiation direction and the radiation area. Thus, the technical effect of improving the communication stability of the electronic device 100 is achieved.

[0061] According to some embodiments of the present application, Figure 2 , Figure 3 , Figure 8 and Fig. 9 As shown, the electronic device 100 further includes: a second convex rib 138 connected to the first end of the sliding bracket 130 and parallel to the first convex rib 116 , and the second convex rib 138 and the fixed bracket 110 enclose a radiation port 139 of the first resonant cavity 136 .

[0062] In this embodiment, the first end of the sliding bracket 130 is connected to the second rib 138, the second rib 138 is opposite to the first rib 116 and the second rib 138 is parallel to the first rib 116, and the bottom surface of the second rib 138 and the fixed bracket 110 enclose a radiation port 139 of the first resonant cavity 136, and the electromagnetic waves in the first resonant cavity 136 are radiated outward through the radiation port 139.

[0063] Specifically, when the sliding bracket 130 is located at the first position, the radiation port 139 is not blocked by the first convex rib 116, and under the joint action of the radiation port 139 and the second convex rib 138, the electromagnetic wave is radiated to the angle area between the fixed bracket 110 and the second convex rib 138. When the sliding bracket 130 is located at the second position, the second convex rib 138 is close to the first convex rib 116, and the electromagnetic wave radiated from the radiation port 139 is radiated to the second through hole 1162 under the blocking action of the second convex rib 138, so as to radiate the electromagnetic wave outward through the second through hole 1162.

[0064] It can be seen that by providing the second rib 138, the radiation direction of the electromagnetic waves can be optimized and adjusted, ensuring that the electronic device 100 radiates electromagnetic waves in the same direction and the same area in the stored state and the unfolded state.

[0065] According to some embodiments of the present application, Figure 1 and Figure 7 As shown, the first through hole 112 and the radiation port 139 are oriented in the same direction.

[0066] In this embodiment, the first through hole 112 and the radiation port 139 are oriented in the same direction. For example, a trapezoidal first through hole 112 may be provided, with the narrow end of the trapezoidal hole facing the radiation port 139 and the wide end facing the opposite side. Correspondingly, the bottom surface of the second rib 138 opposite to the fixing bracket 110 is an inclined surface, which is parallel to the inclined surface in the trapezoidal hole to ensure that the radiation port 139 and the first through hole 112 can radiate electromagnetic waves in the same direction. This allows the electronic device 100 to have substantially consistent radiation performance in the unfolded state and the retracted state, reducing the impact of the movement of the flexible screen 120 on the communication performance of the electronic device 100.

[0067] According to some embodiments of the present application, Fig.14 As shown, the electronic device 100 also includes: a second conductive portion 142, which is disposed on the first rib 116 or the second rib 138, located between the first rib 116 and the second rib 138, and avoids the second through hole 1162; when the sliding bracket 130 is in the second position, the second conductive portion 142 connects the first rib 116 and the second rib 138.

[0068] In this embodiment, the electronic device 100 is further provided with a second conductive portion 142, and the second conductive portion 142 is provided on the first convex rib 116 or the second convex rib 138. When the electronic device 100 is in the unfolded state, the first convex rib 116 is an exposed structure, so providing the second conductive portion 142 on the second convex rib 138 can prevent the second conductive portion 142 from being exposed to the outside.

[0069] Specifically, taking the second conductive portion 142 being disposed on the second convex rib 138 as an example, when the sliding bracket 130 is in the first position, the second conductive portion 142 is separated from the first convex rib 116, and the electromagnetic waves radiated from the radiation port 139 can be radiated outward through the space between the first convex rib 116 and the second convex rib 138. When the sliding bracket 130 is in the second position, the second conductive portion 142 abuts against the first convex rib 116, and the second conductive portion 142 serves as a ground structure. At this time, the electron waves radiated from the radiation port 139 are blocked by the second conductive portion 142, and will not leak out from the space between the first convex rib 116 and the second convex rib 138, thereby ensuring that the electromagnetic waves can enter the second through hole 1162 and radiate outward through the second through hole 1162.

[0070] It can be seen that by providing the second conductive portion 142, the gap between the first convex rib 116 and the second convex rib 138 is closed in the storage state, thereby suppressing the leakage of electromagnetic energy in this area and ensuring that the electromagnetic energy is concentratedly radiated outward from the second through hole 1162, thereby achieving the technical effect of improving the communication stability and reliability of the electronic device 100.

[0071] in, Fig.14 The middle arrow d shows the electromagnetic wave radiation area.

[0072] According to some embodiments of the present application, Figure 2 and Figure 8 As shown, the feeding assembly 160 includes: a dielectric layer 162; a metal layer 164, which is disposed on the dielectric layer 162 and includes a third through hole 1642 connected to the first through hole 112; a feed line 165, which is disposed on the dielectric layer 162 and away from the metal layer 164, and a portion of the feed line 165 is arranged opposite to the third through hole 1642.

[0073] In this embodiment, the structure of the feeding assembly 160 is described. Specifically, the feeding assembly 160 includes a dielectric layer 162, a metal layer 164 and a feed line 165. Different structures are made on both sides of the dielectric layer 162, a microstrip line is made in the lower layer as the feed line 165, and a metal is made in the upper layer as the metal ground of the feed line 165. On this basis, a third through hole 1642 is opened on the metal layer 164 to construct the feeding assembly 160 as a slot antenna. Among them, the microstrip feed line 165 is divided into a first section and a second section, the first section is used to connect the signal source to obtain electromagnetic energy from the signal source, the second section is closely attached to the dielectric layer 162, and the second section is arranged opposite to the third through hole 1642 on the metal layer 164, so that the electromagnetic energy can be radiated outward through the third through hole 1642.

[0074] During the assembly process, the metal layer 164 of the feeding assembly 160 is attached to the first folded edge, and the third through hole 1642 is aligned with the first through hole 112 to ensure that the electromagnetic waves output by the slot antenna can be radiated outward through the first through hole 112 .

[0075] By constructing the feeding assembly 160 as a slot antenna, the feeding assembly 160 itself can be used as an antenna and also as a slot coupling feeding structure, thereby improving the feeding effect of the feeding assembly 160 on the resonant cavity in the stored state.

[0076] According to some embodiments of the present application, Figure 2 and Figure 8 As shown, the cross-sections of the first through hole 112 and the third through hole 1642 are both rectangular, and part of the feed line 165 is perpendicular to the third through hole 1642 .

[0077] In this embodiment, the first through hole 112 and the third through hole 1642 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 third through hole 1642. By configuring the first through hole 112 and the third through hole 1642 as elongated rectangular holes, the transmission effect of electromagnetic waves can be improved, so as to improve the radiation performance of the feeding assembly 160.

[0078] According to some embodiments of the present application, Fig.13 As shown, the cross-sections of the first through hole 112 and the third through hole 1642 are both H-shaped, and a portion of the feed line 165 is arranged opposite to the center line of the second through hole 1162 .

[0079] In this embodiment, the cross-sectional shapes of the first through hole 112 and the third through hole 1642 are both H-shaped, which is equivalent to setting vertical rectangular arms at the left and right ends of the aforementioned rectangular third through hole 1642. The second section of the feed line 165 is still perpendicular to the elongated rectangular gap between the two rectangular arms, and is arranged opposite to the center line of the H-shaped third through hole 1642.

[0080] By setting the first through hole 112 and the third through hole 1642 to be H-shaped, the rectangular arms at both ends of the elongated gap can be used as impedance adjustment structures to control the impedance characteristics of the feeding assembly 160, ensuring that the feeding assembly 160 can match the communication requirements. At the same time, the addition of rectangular arms can also increase the coupling amount of electromagnetic energy and enhance the excitation effect of the resonant cavity in the storage state, so as to further enhance the communication capability of the electronic device 100.

[0081] in, Fig.13 The middle arrow c shows the electromagnetic wave radiation area.

[0082] According to some embodiments of the present application, a cross-sectional dimension of the first through hole 112 is greater than or equal to a cross-sectional dimension of the third through hole 1642 .

[0083] In this embodiment, the cross-sectional shape of the first through hole 112 is consistent with the cross-sectional shape of the third through hole 1642 to ensure that the first through hole 112 and the third through hole 1642 can be connected. On this basis, the cross-sectional size of the first through hole 112 is greater than or equal to the cross-sectional size of the third through hole 1642. Taking the first through hole 112 and the third through hole 1642 as rectangular holes as an example, the width of the first through hole 112 is greater than or equal to the width of the third through hole 1642, and the length of the first through hole 112 is greater than or equal to the length of the third through hole 1642.

[0084] By setting the first through hole 112 to have a size greater than or equal to the third through hole 1642 , it can be ensured that the first through hole 112 will not block the electromagnetic waves output by the feeding component 160 , so as to ensure that the feeding component 160 can obtain good antenna radiation performance.

[0085] 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 embedded in the first through hole 112; and a second plastic part embedded in the second through hole 1162.

[0086] 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 fixed bracket 110 and the sliding bracket 130 can enclose a resonant cavity that limits the transmission direction of the electromagnetic wave. On this basis, the first through hole 112 is filled with a first plastic, and the first plastic part can eliminate the hole structure on the fixed bracket 110, and the plastic will not affect the normal transmission of the electromagnetic wave. By filling the first through hole 112 with plastic, on the one hand, the first through hole 112 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 abrupt appearance of the electronic device 100. On the other hand, the filled plastic can play a role in blocking pollutants, preventing pollutants accumulated in the first through hole 112 from affecting the transmission effect of electromagnetic waves, thereby improving the communication reliability of the electronic device 100.

[0087] Similarly, the second through hole 1162 is filled with a second plastic member, which can eliminate the hole structure on the first rib 116 to prevent the hole structure from being exposed to the user's field of view without affecting the transmission of electromagnetic waves, thereby enhancing the consistency of the exposed structure of the electronic device 100 and reducing the abruptness.

[0088] According to some embodiments of the present application, Figure 3 and Fig. 9 As shown, the fixed bracket 110 and the sliding bracket 130 are both plate-shaped; the fixed bracket 110 is parallel to the sliding bracket 130 .

[0089] In this embodiment, the fixed bracket 110 and the sliding bracket 130 are both metal plates. The fixed bracket 110 and the sliding bracket 130 are parallel to each other, and there is a gap between the fixed bracket 110 and the sliding bracket 130. The first plate surface of the fixed bracket 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 sliding bracket 130. In the storage state, the space between the second plate surface and the third plate surface is the resonant cavity. The fourth plate surface of the sliding bracket 130 is used to support the storage section 124 of the flexible screen 120.

[0090] By setting the fixed bracket 110 and the sliding bracket 130 as a plate, 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 fixed bracket 110 and the sliding bracket 130 are designed as two parallel and spaced large-area metal plates, so that a resonant cavity 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.

[0091] According to some embodiments of the present application, Figure 4 , Figure 5 , Figure 6 and Fig.12 As shown, the electronic device 100 further includes: a shell assembly 170 including an opening 171 , the fixed bracket 110 , the sliding bracket 130 , the feeding assembly 160 and the storage section 124 are all disposed in the shell assembly 170 , and the unfolding section 122 is disposed in the opening 171 .

[0092] In this embodiment, the electronic device 100 further includes a shell assembly 170, which is composed of a first shell 172, a second shell 174 and a back plate 176. The first shell 172 is a fixed shell, the fixed bracket 110 and the feeding assembly 160 are arranged in the first shell 172, the second shell 174 is a movable shell, the sliding bracket 130 is arranged in the second shell 174, and the second shell 174 and the sliding bracket 130 slide synchronously with the extension and retraction of the flexible screen 120. The back plate 176 is divided into two parts, one part of which is fixed on the back side of the first shell 172, and the other part is fixed on the back side of the second shell 174, so as to play a role in shielding the internal structure. The front side opposite to the back plate 176 is the opening 171 of the shell assembly 170, and the unfolded section 122 of the flexible screen 120 is embedded in the opening 171.

[0093] like Figure 4 , Figure 5 and Figure 6 As shown, when the electronic device 100 is in the storage state, the first shell 172 and the second shell 174 are close to each other, and a gap is left between the two back plates 176, and the gap is aligned with the radiation port 139 surrounded by the first folded edge and the second folded edge, so that electromagnetic waves can radiate outward through the radiation port 139 and the gap in sequence. Fig. 9 , Fig.10 and Fig.11 As shown, when the electronic device 100 switches to the unfolded state, the second shell 174 and the back panel 176 thereon extend outward, and the fixing bracket 110 between the two parts of the back panel 176 is exposed to the outside. For the feeding component 160, the clearance of the exposed area is better, and the feeding component 160 can directly radiate electromagnetic waves outward through the first through hole 112.

[0094] According to some embodiments of the present application, Figure 1 and Figure 7 As shown, the electronic device 100 further includes: a circuit board 180 , which is disposed in the shell assembly 170 and connected to the feeding assembly 160 .

[0095] In this embodiment, the electronic device 100 further includes a circuit board 180, which is disposed in the first housing 172, and the circuit board 180 is connected to the fixed bracket 110 via the feeding assembly 160. On the one hand, the circuit board 180 is used as a signal source of the feeding assembly 160, and during operation, the circuit board 180 radiates electromagnetic energy to the external environment through the feeding assembly 160 to achieve signal reception and transmission. The circuit board 180 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 174 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.

[0096] 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 170, and the storage section 124 is connected to the sliding bracket 130. The electronic device 100 also includes: a roller 178, 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 178; a driving assembly 179, 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.

[0097] In this embodiment, the unfolding section 122 of the flexible screen 120 is fixed on the shell assembly 170, specifically connected to the first shell 172, and the storage section 124 is connected to the movable sliding bracket 130. On this basis, the electronic device 100 also includes a roller 178 and a driving assembly 179, the roller 178 is rotatably connected to the sliding bracket 130, and the unfolding section 122 is wound around the peripheral side of the roller 178 to the sliding bracket 130 located on the second side of the fixed bracket 110. The driving assembly 179 is connected to the fixed bracket 110, and the driving assembly 179 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 179, 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 179.

[0098] When the user needs to increase the display size, the driving assembly 179 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 178 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 179 drives the sliding bracket 130 and the roller 178 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.

[0099] At the same time, in the process of adjusting the display size of the flexible screen 120, the roller 178 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 178 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.
