Description

Technical Field

[0001] This application belongs to the technical field of electronic devices, and particularly relates to an electronic device. Background Art

[0002] Currently, the screen area is mainly enlarged or reduced through a folding screen. Different regions of the folding screen are respectively fixed on different folding bodies, and the folding bodies are relatively rotated through a hinge to drive the folding screen to complete the folding or unfolding action, so as to adjust the screen area.

[0003] In the related art, when the folding screen is in the unfolded state, the antennas located around the body form a "mouth" - shaped antenna layout similar to that of a straight - bar mobile phone. When in the folded state, since there is no antenna segment on the hinge side, the antenna in the folded state belongs to a "C" - shaped layout.

[0004] However, the "C" - shaped antenna layout lacks one - side antenna segment, resulting in the inability to layout some antenna frequency bands, so that the product has technical problems of poor signal in the folded state and poor Internet access and call experience in the folded state. Summary of the Invention

[0005] This application aims to provide an electronic device, at least solving the technical problems of poor signal in the folded state and poor Internet access and call experience in the folded state.

[0006] To solve the above - mentioned technical problems, this application is implemented as follows:

[0007] An embodiment of this application provides an electronic device, which includes: a hinge assembly; a plurality of folding bodies, the plurality of folding bodies are connected in sequence, and adjacent two folding bodies are connected through the hinge assembly, and the plurality of folding bodies include an unfolded state and a folded state; a first antenna, the first antenna is arranged on the folding body, the first antenna is located on the periphery of the folding body, and the first antenna avoids the hinge assembly; a second antenna, the second antenna is arranged on the hinge assembly; wherein, when the plurality of folding bodies are in the unfolded state, the first antennas form a first antenna array surrounding the plurality of folding bodies; when the plurality of folding bodies are in the folded state, the first antenna and the second antenna form a second antenna array surrounding the plurality of folding bodies.

[0008] In this technical solution, an electronic device capable of changing the screen display size through a folding action is defined to meet the diverse needs of users.

[0009] The plurality of folding bodies include an unfolded state and a folded state. In the unfolded state, the plurality of folding bodies are laid flat on the same plane, and at this time, the display area is the largest. In the folded state, the plurality of folding bodies are stacked together, and at this time, the display area is the smallest.

[0010] A first antenna is provided on the folding body, and a second antenna is provided on the hinge assembly. Among them, the first antenna is provided on the circumferential side surface of the folding body, and the first antenna covers multiple orientations of the folding body. One side of the folding body is connected to the hinge assembly, and the first antenna avoids the side where the hinge assembly is located.

[0011] When multiple folding bodies are switched to the unfolded state, the multiple first antennas arranged on the circumferential side of the folding body can be fully exposed, and the multiple first antennas surround the unfolded multiple folding bodies to form a first antenna array in the shape of a "mouth", thereby obtaining a larger antenna frequency band and enabling the electronic device to have excellent Internet access experience and call experience in the unfolded state.

[0012] Correspondingly, when multiple folding bodies are switched to the folded state, the multiple first antennas arranged on the circumferential side of the folding body can cooperate with the second antennas arranged on the hinge assembly to form a second antenna array. The second antenna array surrounds the four sides of the multiple folding bodies stacked together, that is, the second antenna array is also in a "mouth" - shaped layout to obtain a larger antenna frequency band, so that the electronic device can have an Internet access experience and call experience close to that in the unfolded state in the folded state.

[0013] It can be seen that in this application, by providing the second antenna on the hinge assembly, the second antenna can cover the area blocked by the hinge assembly in the folded state, enabling the electronic device to have an antenna array in a "mouth" - shaped layout in the folded state, replacing the "C" - shaped layout scheme in the related art, thereby reducing the frequency band loss of the electronic device in the folded state, solving the technical problems of poor signal in the folded state and poor Internet access and call experience in the folded state in the related art, and further achieving the technical effects of optimizing the antenna layout of the electronic device, improving the signal strength of the electronic device, and enhancing the user experience.

[0031] Combine the following Figures 1 to 10 An electronic device according to an embodiment of the present application is described.

[0032] like Figure 1 and Figure 2 As shown, according to some embodiments of the present application, the electronic device 100 includes: a hinge assembly 110; a plurality of folding bodies 120, the plurality of folding bodies 120 are connected in sequence, and two adjacent folding bodies 120 are connected through the hinge assembly 110, and the plurality of folding bodies 120 include an unfolded state and a folded state; a first antenna 130, the first antenna 130 is arranged on the folding body 120, the first antenna 130 is located on the periphery of the folding body 120, and the first antenna 130 avoids the hinge assembly 110; a second antenna 140, the second antenna 140 is arranged on the hinge assembly 110; wherein, when the plurality of folding bodies 120 are in the unfolded state, the first antenna 130 forms a first antenna array 132 surrounding the plurality of folding bodies 120; when the plurality of folding bodies 120 are in the folded state, the first antenna 130 and the second antenna 140 form a second antenna array 142 surrounding the plurality of folding bodies 120.

[0033] In this embodiment, an electronic device 100 is defined that can change the screen display size through a folding action to meet the diverse needs of users.

[0034] Specifically, the electronic device 100 includes a hinge assembly 110 and a folding body 120. There are multiple folding bodies 120, and the folding bodies 120 are used to fix the flexible screen. The multiple folding bodies 120 are connected in sequence through hinges, that is, two adjacent folding bodies 120 are hinged on the same hinge, so that the multiple folding bodies 120 can change the posture of the electronic device 100 by rotating relative to the hinge assembly 110.

[0035] Specifically, the multiple folding bodies 120 include an unfolded state and a folded state. In the unfolded state, the multiple folding bodies 120 are laid flat on the same plane, and the display area is maximized. In the folded state, the multiple folding bodies 120 are stacked together, and the display area is minimized.

[0036] Taking the electronic device 100 as a double-folding mobile phone as an example, the number of folding bodies 120 is 2, and the two folding bodies 120 are connected by a hinge assembly 110. When the two folding bodies 120 are switched to the unfolded state by rotating, the display size of the flexible screen is larger, which can enhance the user's video viewing experience or gaming experience. When the two folding bodies 120 are switched to the folded state by rotating, the display size is halved, which can be convenient for users to hold.

[0037] On this basis, a first antenna 130 is disposed on the folding body 120, and a second antenna 140 is disposed on the hinge assembly 110. The first antenna 130 is disposed on the peripheral side of the folding body 120, and the first antenna 130 covers multiple directions of the folding body 120. One side of the folding body 120 is connected to the hinge assembly 110, and this side is blocked by the hinge assembly 110, so the first antenna 130 avoids the side where the hinge assembly 110 is located.

[0038] Taking the electronic device 100 as a double-folding mobile phone as an example, the opposite sides of the left and right folding bodies 120 are used to connect the hinge assembly 110, and the first antenna 130 avoids this area. The first antenna 130 is arranged in the other three directions of the two folding bodies 120 except the opposite sides.

[0039] Taking the electronic device 100 as a three-fold mobile phone as an example, the middle folding body 120 is connected to the hinge assembly 110 on both sides, so the middle folding body 120 is only arranged with the first antenna 130 on the upper and lower sides, and the folding bodies 120 at the left and right ends are consistent with the layout of the double-folding mobile phone, and the first antenna 130 is arranged in three directions.

[0040] When the multiple folding bodies 120 switch to the unfolded state, the multiple first antennas 130 arranged on the sides of the folding bodies 120 can be fully exposed, and the multiple first antennas 130 surround the unfolded multiple folding bodies 120 to form a "mouth"-shaped first antenna array 132, thereby obtaining a larger antenna frequency band, so that the electronic device 100 can have excellent Internet access and call experience in the unfolded state.

[0041] Correspondingly, when multiple folding bodies 120 are switched to the folded state, multiple first antennas 130 arranged on the peripheral side of the folding bodies 120 can cooperate with the second antenna 140 arranged on the hinge assembly 110 to form a second antenna array 142. The second antenna array 142 surrounds the four sides of the multiple folding bodies 120 stacked together, that is, the second antenna array 142 is also in a "mouth" - shaped layout to obtain a larger antenna frequency band, so that the electronic device 100 can have an Internet access experience and a call experience similar to that in the unfolded state in the folded state.

[0042] It can be seen that in this application, by setting the second antenna 140 on the hinge assembly 110, the second antenna 140 can cover the area blocked by the hinge assembly 110 in the folded state, enabling the electronic device 100 to have an antenna array with a "mouth" - shaped layout in the folded state, replacing the "C" - shaped layout scheme in the related art, thereby reducing the frequency band loss of the electronic device 100 in the folded state, solving the technical problems of poor signal in the related art in the folded state and poor Internet access and call experiences in the folded state, and further achieving the technical effects of optimizing the antenna layout of the electronic device 100, enhancing the signal strength of the electronic device 100, and improving the user experience.

[0043] As Figure 1 、 Figure 2 and Figure 3 shown, in some embodiments, optionally, the hinge assembly 110 includes: a hinge body 112, with both ends of the hinge body 112 respectively connected to two folding bodies 120; a cover body 114, connected to the hinge body 112. When multiple folding bodies 120 are in the folded state, the cover body 114 is located on the side of the hinge body 112 facing away from the folding bodies 120, and the second antenna 140 is arranged on the cover body 114.

[0044] In this embodiment, the hinge assembly 110 includes a hinge body 112 and a cover body 114. Both sides of the hinge assembly 110 are respectively connected to two adjacent folding bodies 120. Both sides of the hinge assembly 110 can drive the two folding bodies 120 to rotate relative to each other, thereby realizing the unfolding and folding actions of the two folding bodies 120, enabling the flexible screen to adjust the display area along with the actions of the folding bodies 120.

[0045] Among them, when multiple folding bodies 120 are in the unfolded state, the hinge body 112 is located between the two folding bodies 120. At this time, the back plates of the two folding bodies 120 can block the hinge body 112. When multiple folding bodies 120 are in the folded state, the multiple folding bodies 120 are stacked on the same side of the hinge body 112, and the hinge body 112 cannot be blocked by the outer surface of the folding bodies 120.

[0046] On this basis, the hinge assembly 110 also includes a cover body 114, which is connected to the hinge body 112. When the multiple folding bodies 120 are in a folded state or a posture between the unfolded state and the folded state, the cover body 114 can provide shielding on the outside of the hinge assembly 110 to form an exposed surface of the hinge assembly 110.

[0047] It can be seen that, by providing the cover 114, on the one hand, the exposed hinge body 112 can be prevented from causing an awkward feeling, thereby improving the integrity of the exposed surface of the electronic device 100. On the other hand, the cover 114 can protect the hinge body 112 from impact, preventing the hinge body 112 with a precise structure from being damaged by external impact, thereby reducing the failure rate of the hinge body 112. On the other hand, the cover 114 can block pollutants, reducing the probability of the hinge body 112 being corroded or blocked by pollutants, thereby extending the service life of the hinge assembly 110.

[0048] like Figure 3 As shown, in some embodiments, optionally, the second antenna 140 is located between the cover body 114 and the hinge body 112 .

[0049] In this embodiment, the second antenna 140 is clamped between the cover body 114 and the hinge body 112, and the second antenna 140 is arranged on the inner side of the cover body 114. The second antenna 140 can be protected by the cover body 114 to prevent the second antenna 140 from being damaged by impact or corroded by pollutants, thereby reducing the failure rate of the second antenna 140 and extending the service life of the second antenna 140.

[0050] Moreover, in this embodiment, the second antenna 140 can reasonably utilize the space between the hinge body 112 and the cover body 114, and has little impact on the stacking space layout of the hinge assembly 110. Only a few matching components of the second antenna 140 need to be added to the main board to improve the signal strength of the electronic device 100 in the folded state, without affecting the thickness, width and feel of the entire device, thereby providing convenient conditions for the miniaturized design of the electronic device 100.

[0051] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the cover 114 includes a through hole 1142 , which is arranged opposite to the second antenna 140 , and the electronic device 100 further includes: a non-metallic inlay 1144 , which is embedded in the through hole 1142 .

[0052] In this embodiment, the cover body 114 is formed by metal material. Selecting metal material to prepare the cover body 114 can improve the strength of the cover body 114, thereby providing reliable protection for the hinge body 112 and the second antenna 140 and reducing the damage to the hinge body 112 and the second antenna 140 caused by external impact.

[0053] On the other hand, the surface of the cover 114 made of metal material is glossy and has a good touch, which can improve the texture of the exposed surface of the electronic device 100, thereby improving the user experience.

[0054] On this basis, a through hole 1142 is set on the cover body 114. After assembly, the through hole 1142 is opposite to the second antenna 140 on the inner side of the cover body 114. By setting the through hole 1142, the metal cover body 114 can be prevented from shielding the signal of the second antenna 140, thereby improving the signal transmission reliability of the second antenna 140.

[0055] Specifically, a non-metallic inlay 1144 is embedded in the through hole 1142 . The non-metallic inlay 1144 can cover the second antenna 140 inside by filling the through hole 1142 , and the non-metallic inlay 1144 will not shield the signal.

[0056] By providing the non-metallic insert 1144, on the one hand, the cover 114 can have a flat outer surface, preventing the concave through hole 1142 from affecting the user's hand feeling. On the other hand, the non-metallic insert 1144 can resist impact and prevent pollutants from entering the through hole 1142, thereby providing effective protection for the second antenna 140, reducing the failure rate of the second antenna 140, and extending the service life of the second antenna 140.

[0057] Specifically, the non-metal insert 1144 is molded in the through hole 1142 by an injection molding process.

[0058] like Figure 3 , Figure 4 , Figure 5 and Fig. 9 As shown, in some embodiments, optionally, the electronic device 100 also includes: a flexible circuit board 150, the flexible circuit board 150 is arranged on the side of the hinge body 112 facing the cover body 114, the flexible circuit board 150 connects the two folding bodies 120 connected by the hinge body 112, and the flexible circuit board 150 also includes a connecting end 152, and the connecting end 152 is connected to the second antenna 140.

[0059] In this embodiment, a flexible circuit board 150 is fixed on the hinge body 112. The flexible circuit board 150 spans the hinge body 112. Both ends of the flexible circuit board 150 are respectively connected to the two folding bodies 120 connected to the hinge body 112, so that the flexible circuit board 150 can transmit signals between the first folding body 120 and the second folding body 120.

[0060] Specifically, when the plurality of folding bodies 120 are in an unfolded state, the first antennas 130 on different folding bodies 120 work together through the flexible circuit board 150 , thereby transmitting and receiving signals through the first antenna array 132 .

[0061] On this basis, a connection end 152 is further provided in the middle section of the flexible circuit board 150, the connection end 152 extends outward, and the connection end 152 is electrically connected to the second antenna 140. By providing the connection end 152, the flexible circuit board 150 can take into account the electrical connection requirements of the second antenna 140, so that the second antenna 140 can be connected to the mainboard through the flexible circuit board 150.

[0062] Specifically, when the plurality of folding bodies 120 are in a folded state, the second antenna 140 and the first antenna 130 on the folding body 120 work together through the flexible circuit board 150 , thereby transmitting and receiving signals through the second antenna array 142 .

[0063] With this structural layout, the second antenna 140 can be closely connected to the flexible circuit board 150 inside the hinge assembly 110 , thereby reducing the wiring difficulty and structural complexity in the hinge assembly 110 .

[0064] Specifically, the flexible circuit board 150 and the keel on the hinge body 112 are connected together through the second adhesive layer 172, so that the keel provides positioning and support for the flexible circuit board 150, avoiding misalignment of the flexible circuit board 150 during bending, thereby reducing the failure rate of the flexible circuit board 150.

[0065] like Figure 4 and Figure 5 As shown, in some embodiments, optionally, the electronic device 100 further includes: a reinforcing component 154 , which is connected to the second antenna 140 and is located between the second antenna 140 and the flexible circuit board 150 , and is used to support the flexible circuit board 150 .

[0066] In this embodiment, a reinforcing component 154 is connected to a side of the second antenna 140 facing away from the cover 114 . Specifically, the reinforcing component 154 may be fixed to the second antenna 140 via a first adhesive layer 170 .

[0067] After assembly is completed, the side of the reinforcing component 154 facing away from the second antenna 140 abuts against the side of the flexible circuit board 150 facing away from the hinge body 112, so that the reinforcing component 154 can provide positioning and support for the flexible circuit board 150, and specifically cooperate with the keel in the aforementioned embodiment to position the flexible circuit board 150 on both sides, so as to further reduce the probability of misalignment of the flexible circuit board 150, thereby achieving the technical effect of reducing the failure rate of the flexible circuit board 150.

[0068] Specifically, the reinforcing member 154 is a steel sheet, which has a high structural strength and can improve the effectiveness of the positioning support. On the other hand, the steel sheet can maintain a small thickness while having a high structural strength, thereby providing convenient conditions for the miniaturization design of the hinge assembly 110 and the electronic device 100.

[0069] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the second antenna 140 includes: a substrate 144 , which is clamped between the hinge body 112 and the cover body 114 ; and an antenna body 146 , which is disposed on a side of the substrate 144 facing the cover body 114 .

[0070] In this embodiment, the second antenna 140 includes a substrate 144 and an antenna body 146 , and the substrate 144 is sandwiched between the hinge body 112 and the cover body 114 .

[0071] The antenna body 146 is a radiator, and the signal is transmitted from the main board and the flexible circuit board 150 to the antenna body 146, and then radiated by the antenna body 146. Specifically, the antenna body 146 is formed on the side of the substrate 144 facing the cover 114 through a printing process. After assembly, the antenna body 146 is arranged opposite to the non-metallic insert 1144 to ensure that the metal cover 114 does not block the signal of the antenna body 146.

[0072] By setting up the substrate 144, the antenna body 146 can be positioned, supported and protected. On the one hand, the probability of the antenna body 146 being damaged by the hinge body 112 during the assembly process and use is reduced. On the other hand, the probability of the antenna body 146 being misplaced or even falling off is reduced, thereby achieving the technical effect of improving the structural reliability of the second antenna 140 and reducing the failure rate of the second antenna 140.

[0073] like Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, optionally, a boss 1146 is provided on the side of the cover body 114 facing the hinge body 112, and the boss 1146 includes a mounting hole 1148. The electronic device 100 also includes: a connector 160, which is passed through the mounting hole 1148 and is used to connect the cover body 114 and the hinge body 112.

[0074] In this embodiment, a boss 1146 is disposed on the inner side of the cover body 114 , and a mounting hole 1148 is disposed in the boss 1146 , and the mounting hole 1148 is a blind hole.

[0075] On this basis, the hinge body 112 is fixed to the inner side of the cover body 114 by means of the connecting piece 160 penetrating into the mounting hole 1148 .

[0076] Specifically, the connecting member 160 is a screw, which passes through a partial area of ​​the hinge body 112 , and the end of the screw is screwed into the mounting hole 1148 , and the head of the screw presses the hinge body 112 onto the boss 1146 .

[0077] After the assembly is completed, the hinge body 112 and the cover body 114 clamp the base plate 144 therebetween to prevent the base plate 144 from jumping between the cover body 114 and the hinge body 112 .

[0078] In this embodiment, the hinge body 112 and the second antenna 140 can be simultaneously installed on the cover body 114 , the structural complexity is reduced and the assembly difficulty is relatively low, which is conducive to reducing the production cost of the electronic device 100 .

[0079] like Fig. 9 As shown, in some embodiments, optionally, the base plate 144 includes a limiting groove 1442 , and the boss 1146 is located in the limiting groove 1442 .

[0080] In this embodiment, a limiting groove 1442 is provided on the substrate 144, and the size and shape of the limiting groove 1442 are adapted to the boss 1146. During the assembly process, the boss 1146 can be inserted into the limiting groove 1442 to achieve initial positioning of the substrate 144 on the cover body 114, thereby improving the assembly accuracy of the second antenna 140.

[0081] On this basis, the boss 1146 can also limit the substrate 144 through the limiting groove 1442. Specifically, the boss 1146 can prevent the substrate 144 from moving in the X and Y directions. Combined with the clamping positioning structure in the aforementioned embodiment that limits the jumping of the substrate 144 in the Z direction, the substrate 144 can be positioned in all directions, so that the second antenna 140 can be accurately positioned at the specified position, thereby improving the positioning accuracy of the second antenna 140 and improving the signal transmission reliability of the second antenna 140.
