Abstract
Description
Technical Field
[0001] This application relates to the field of electronic equipment technology, and in particular to an electronic device. Background Technology
[0002] Currently, mobile phones and other electronic devices are increasingly trending towards larger screens and ultra-thin designs, and foldable electronic devices are gradually emerging.
[0003] In existing technologies, a reinforcing steel sheet is installed under the screen of foldable electronic devices. This reinforcing steel sheet is connected to the device's mid-frame through conductive foam. However, the conductive foam has high conductivity impedance, making it very prone to radio frequency spurious emission (RSE) and passive intermodulation (PIM) problems. Therefore, gold-plated components need to be installed between the conductive foam, the mid-frame, and the reinforcing steel sheet to reduce the overlap impedance. However, this increases the device cost, and the conductive foam is prone to squeezing the foldable screen, increasing the risk of deformation of the foldable screen structure. Summary of the Invention
[0004] This application provides an electronic device to solve the problem in the prior art that the use of conductive foam increases the cost of electronic devices and increases the risk of deformation of the foldable screen structure.
[0005] In a first aspect, embodiments of this application provide an electronic device, including: a frame structure including an insulated ground portion and an antenna portion; a screen body connected to one side of the frame structure in a first direction, the screen body including a main body and a reinforcing portion, the reinforcing portion being disposed on the side surface of the main body facing the frame structure in the first direction, the reinforcing portion and the main ground portion being spaced apart in the first direction and insulated from each other, so that the reinforcing portion and the main ground portion form a coupling capacitor.
[0006] Thus, in the electronic device provided in this application embodiment, the electronic device includes a frame structure and a screen. The frame structure includes an insulated ground portion and an antenna portion. The screen structure is connected to one side of the frame structure in a first direction. The screen includes a screen and a reinforcing portion. The reinforcing portion is disposed on the surface of the main body facing the frame structure in the first direction. The reinforcing portion and the ground portion are spaced apart in the first direction and insulated from each other, so that the reinforcing portion and the ground portion form a coupling capacitor. This allows the current excited by the antenna portion in the reinforcing portion to be coupled to the ground portion of the frame structure, reducing the risk of forming a resonant cavity between the reinforcing portion and the frame structure, which would generate clutter and affect antenna performance. Furthermore, it eliminates the need for conductive foam, thus improving the problem of increased cost of electronic devices and increased risk of screen structure deformation caused by the use of conductive foam.
[0007] Therefore, in this embodiment, by spacing the reinforcing part and the main ground part apart and insulating them from each other in the first direction, the reinforcing part and the main ground part form a coupling capacitor, so that the current excited by the reinforcing part can be coupled to the main ground part. There is no need to set conductive foam between the reinforcing part and the main ground part, which reduces the manufacturing cost of electronic devices and reduces the risk of the conductive foam squeezing the screen structure, causing the screen structure to deform.

The setting of the first direction X, the second direction Y, and the third direction Z is only to more clearly illustrate the structure of the connecting member and electronic device provided in the embodiments of this application, and does not limit the direction of the embodiments of this application.
[0027] In existing technologies, conductive foam is placed between the reinforcing part and the frame structure. The current excited on the reinforcing part is introduced into the frame structure through the conductive foam. However, in order to reduce the overlap impedance between the conductive foam and the reinforcing part and the frame structure, gold-plated parts are often placed at both ends of the conductive foam, which increases the cost of the electronic device. The gold-plated sheet needs to be welded to other structures. In order to avoid the gold-plated sheet from being burned through, the gold-plated sheet needs to have a certain thickness, which also increases the overall thickness of the electronic device. Moreover, in order to maintain the connection reliability between the conductive foam and the reinforcing part and the frame structure, the conductive foam is in a compressed state between the reinforcing part and the frame structure. The conductive foam provides a compressive force on the screen structure, causing the screen structure to deform. To overcome the above problems, this application provides an electronic device, as follows.
[0028] See Figures 1 to 3 , Figure 1 This is a schematic diagram of the electronic device structure according to some embodiments of this application; Figure 2 Exploded views of electronic devices according to some embodiments of this application; Figure 3 for Figure 1 Sectional view at point AA.
[0029] Firstly, such as Figures 1 to 3 As shown, this application embodiment provides an electronic device 100, which includes a frame structure 110 and a screen structure 120. The frame structure 110 includes a main ground portion 111 and an antenna portion 112 that are insulated from each other. The screen structure 120 is connected to one side of the frame structure 110 in a first direction X. The screen structure 120 includes a screen 121 and a reinforcing portion 122. The reinforcing portion 122 is disposed on the side surface of the screen 121 facing the frame structure 110 in the first direction X. The reinforcing portion 122 and the main ground portion 111 are spaced apart in the first direction X and insulated from each other, so that the reinforcing portion 122 and the main ground portion 111 form a coupling capacitor.
[0030] The frame structure 110 is the middle frame structure of the electronic device 100. The middle frame structure typically includes a base plate and side plates surrounding the edge of the base plate. The base plate of the middle frame structure is usually plate-shaped and is used to mount and support the components of the electronic device 100, including processors, heat spreaders, and other functional components. The base plate and side plates are usually made of aluminum alloy.
[0031] The antenna section 112 includes an antenna body (not shown) and a clearance area (not shown). For example, the antenna body is disposed on a side plate, and the antenna bodies are spaced apart by a slot structure. The main ground section 111 may be disposed on a base plate, and the clearance area provides insulation between the main ground section 111 and the antenna body.
[0032] A reinforcing part 122 is disposed on the side of the main body facing the frame structure 110 in the first direction X. The reinforcing part 122 is made of metal and is used to support and protect the screen 121 of the screen structure 120. For example, the reinforcing part 122 is made of stainless steel or titanium alloy. The reinforcing part 122 and the screen 121 are spaced apart in the first direction X and insulated from each other to form a coupling capacitor. This allows the current excited by the antenna part 112 in the reinforcing part 122 to be coupled and conducted to the main ground part 111, reducing the risk of interference to the antenna body caused by resonance between the reinforcing part 122 and the frame structure 110.
[0033] Optionally, the screen structure 120 and the frame structure 110 are directly connected, or the screen structure 120 and the frame structure 110 are connected by an insulating structural member, and the reinforcing part 122 is suspended on one side of the screen 121 or an insulating support member is provided between the reinforcing part 122 and the screen 121.
[0034] In the electronic device 100 provided in this application embodiment, the electronic device 100 includes a frame structure 110 and a screen structure 120. The frame structure 110 includes a main ground portion 111 and an antenna portion 112 that are insulated from each other. The screen structure 120 is connected to one side of the frame structure 110 in the first direction X. The screen structure 120 includes a screen 121 and a reinforcing portion 122. The reinforcing portion 122 is disposed on the side surface of the screen 121 facing the frame structure 110 in the first direction X. The reinforcing portion 122 and the main ground portion 111 are spaced apart in the first direction X and insulated from each other, so that the reinforcing portion 122 and the main ground portion 111 form a coupling capacitor. This allows the current excited by the antenna portion 112 to couple the reinforcing portion 122 to the main ground portion 111 of the frame structure 110, reducing the risk of forming a resonant cavity between the reinforcing portion 122 and the frame structure, which would generate clutter and affect antenna performance. Furthermore, it eliminates the need for conductive foam, thus improving the problem of increased cost of the electronic device 100 and increased risk of deformation of the screen structure 120 due to the use of conductive foam. Therefore, in this embodiment, by making the reinforcing part 122 and the main ground part 111 spaced apart and insulated from each other in the first direction X, the reinforcing part 122 and the main ground part 111 form a coupling capacitor, so that the current excited by the reinforcing part 122 can be coupled to the main ground part 111. There is no need to provide conductive foam between the reinforcing part 122 and the main ground part 111, which reduces the manufacturing cost of the electronic device 100 and reduces the risk of the conductive foam squeezing the screen structure 120, causing the screen structure 120 to deform.
[0035] In some embodiments, such as Figure 2 and Figure 3 As shown, the electronic device 100 also includes an insulating part 130, which is disposed between the frame structure 110 and the screen structure 120.
[0036] Optionally, the insulating part 130 is foam, and the two ends of the foam in the first direction X are bonded to the frame structure 110 and the screen structure 120. The insulating part 130 is insulated from the reinforcing part 122, but the insulation is not insulated from the frame structure 110.
[0037] Optionally, the insulating part 130 is disposed between the reinforcing part 122 and the main ground part 111. The insulating part 130 is used to isolate the reinforcing part 122 and the main ground part 111 to reduce the risk of accidental connection and conduction between the reinforcing part 122 and the main ground part 111 under the action of external force.
[0038] Optionally, a plurality of insulating portions 130 are provided between the frame structure 110 and the screen structure 120.
[0039] In these embodiments, an insulating portion 130 is provided between the frame structure 110 and the screen structure 120. The insulating portion 130 provides support for the frame structure 110 and the screen structure 120 and separates the frame structure 110 and the screen structure 120, thus playing a role in buffering and absorbing energy.
[0040] In some embodiments, such as Figure 2 and Figure 3 As shown, the size L1 of the first gap between the reinforcing part 122 and the main ground part 111 in the first direction X satisfies: 0 < L1 ≤ 0.15 mm.
[0041] Optionally, an insulating part 130 is provided between the reinforcing part 122 and the main ground part 111, and the first gap dimension between the reinforcing part 122 and the main ground part 111 in the first direction X is the length of the insulating part 130 in the first direction X.
[0042] In these embodiments, the size L1 of the first gap between the reinforcing part 122 and the main ground part 111 in the first direction X satisfies: 0 < L1 ≤ 0.15 mm, in order to improve the problem that the current of the reinforcing part 122 cannot be coupled to the main ground part 111 in time due to the excessively large gap between the reinforcing part 122 and the main ground part 111 in the first direction X, resulting in excessively small coupling capacitance and thus generating clutter between the reinforcing part 122 and the frame structure 110, which affects the antenna body 1121.
[0043] See Figure 4 and Figure 5 , Figure 4 Exploded views of electronic devices according to other embodiments of this application; Figure 5 This is a schematic diagram of the frame structure of an electronic device according to other embodiments of this application.
[0044] In some embodiments, such as Figure 4 and Figure 5As shown, the antenna section 112 includes an antenna body 1121 and a clearance area 1122. The clearance area 1122 is disposed between the antenna body 1121 and the main ground section 111. Along the first direction X, a shielding section 140 is disposed between the clearance area 1122 and the reinforcement section (not shown).
[0045] The clearance area 1122 is used to insulate and isolate at least one antenna body 1121 from the main ground portion 111. The shape of the clearance area 1122 can be set according to the shape of the antenna body 1121. Multiple antenna bodies 1121 can be provided in the electronic device 100, and correspondingly, multiple clearance areas 1122 can also be provided. The shielding portion 140 and the antenna body 1121 are mutually insulated.
[0046] An insulating structure is provided within the clearance area 1122, and a shielding part 140 covers a portion of the insulating structure of the clearance area 1122. For example, the insulating structure is made of plastic. The shielding part 140 is made of metal; for example, the shielding part 140 is made of copper foil.
[0047] Optionally, the shielding part 140 is bonded to the clearance area 1122, or a portion of the shielding part 140 extends out of the clearance area 1122 and is connected to the main ground part 111.
[0048] In these embodiments, a shielding portion 140 is provided between the first direction X clearance area 1122 and the reinforcement portion 122. The shielding portion 140 can reflect part of the energy of the antenna body 1121, reduce the energy of the antenna body 1121 coupled to the reinforcement portion (not shown), and reduce the risk of clutter between the reinforcement portion (not shown) and the frame structure 110 affecting the performance of the antenna body 1121.
[0049] In some embodiments, such as Figure 4 and Figure 5 As shown, the shielding part 140 covers the entire clearance area 1122.
[0050] Optionally, the shape of the shield 140 matches the shape of the clearance area 1122.
[0051] In these embodiments, the shielding portion 140 covers the entire clearance area 1122 to improve the shielding effect of the shielding portion 140 on the antenna body 1121, reduce the energy radiated from the antenna body 1121 to the clearance area 1122, and reduce the risk of clutter generated between the reinforcing portion 122 and the frame structure 110 affecting the performance of the antenna body 1121.
[0052] Please see Figure 6 , Figure 6 for Figure 1 Sectional view at BB.
[0053] In some embodiments, such as Figures 4 to 6As shown, the shielding part 140 is connected to the main ground part 111 and is electrically connected to it.
[0054] The shielding part 140 is electrically connected to the main ground part 111, and the shielding part 140 and the reinforcing part 122 are isolated and insulated from each other. The portion of the reinforcing part 122 whose projection in the first direction X coincides with the clearance area 1122 can form a coupling capacitor with the shielding part 140.
[0055] Optionally, the size of the shielding portion 140 in the first direction X is less than or equal to 0.05 mm, in order to reduce the risk that the shielding portion 140 is too thick and has too great an impact on the performance of the antenna body 1121 in the first direction X, resulting in a decrease in the communication quality of the electronic device 100.
[0056] Optionally, the shielding portion 140 and the main ground portion 111 are welded together, which improves the connection reliability between them. For example, the shielding portion 140 and the main ground portion 111 are ultrasonically welded. A welding position is provided on the shielding portion 140, located in a portion of the shielding portion 140 extending out of the clearance area 1122 and aligned with the main ground portion 111 along a first direction X. The shielding portion 140 and the main ground portion 111 are ultrasonically welded together at this welding position. One or more welding positions may be provided on a single shielding portion 140.
[0057] In these embodiments, the shielding part 140 is connected to the main ground part 111 and is interconnected, so that the shielding part 140 can both reflect the energy of the antenna body 1121 acting on the reinforcement part 122, and form a coupling capacitor with the reinforcement part 122 to couple the excitation current on the reinforcement part 122 to the main ground part 111, thereby further reducing the risk of clutter being generated between the reinforcement part 122 and the frame structure 110, which may interfere with the antenna performance.
[0058] In some embodiments, such as Figures 4 to 6 As shown, a second gap is provided between the shielding part 140 and the reinforcing part 122 along the first direction X. The size L2 of the second gap in the first direction X satisfies that L2≥0.05mm.
[0059] Optionally, an insulating separator is provided between the shielding part 140 and the reinforcing part 122 to reduce the risk of accidental contact and conduction between the shielding part 140 and the reinforcing part 122 under external force.
[0060] Optionally, the reinforcing part 122 is suspended on one side of the shielding part 140 in the first direction X, which reduces the risk of the reinforcing part 122 being squeezed and deformed by the shielding part 140 or the insulating isolator.
[0061] Optionally, the shielding portion 140 covers the clearance area 1122 along the first direction X. The shielding portion 140 weakens the intensity of radiation from the antenna body 1121 to the reinforcement portion 122, but it also weakens the effect of the clearance area 1122 in the first direction X. Therefore, the thickness of the shielding portion 140 should not be too thick. Optionally, the thickness of the shielding portion 140 in the first direction X should be less than 0.1 mm. For example, the thickness of the shielding portion 140 in the first direction X is 0.05 mm.
[0062] In these embodiments, a second gap is provided between the shielding part 140 and the reinforcing part 122 to reduce the risk of the shielding part 140 squeezing the reinforcing part 122 under external force, causing the screen structure 120 to deform. The size L2 of the second gap in the first direction X satisfies L2≥0.05mm to reduce the risk of the shielding part 140 squeezing the reinforcing part 122 under external force due to the second gap being too small, causing the screen structure 120 to deform.
[0063] See Figure 7 , Figure 7 for Figure 5 Sectional view at CC.
[0064] In some embodiments, such as Figure 4 , Figure 5 and Figure 7 As shown, the shielding part 140 includes an adhesive layer 141 and a shielding layer 142. The adhesive layer 141 is bonded to the clearance area 1122, and the shielding layer 142 is disposed on the side of the adhesive layer 141 opposite to the clearance area 1122 in the first direction X.
[0065] Optionally, the adhesive layer 141 is an insulating adhesive to improve the insulation reliability between the shielding layer 142 and the antenna body 1121.
[0066] Optionally, the adhesive layer 141 covers the shielding layer 142 on the side of the shielding structure 120 facing away from the shielding structure 120 in the first direction X, thereby improving the connection reliability between the adhesive layer 141 and the shielding layer 142.
[0067] Optionally, the shielding layer 142 is a copper foil, and the thickness of the shielding layer 142 is no more than 0.015 mm. For example, the thickness of the shielding layer 142 is 0.012 mm.
[0068] Optionally, the thickness of the adhesive layer 141 is no more than 0.01 mm. For example, the thickness of the adhesive layer 141 is 0.008 mm.
[0069] In these embodiments, the adhesive layer 141 is bonded to the clearance area 1122, and the shielding layer 142 is disposed on the side of the adhesive layer 141 facing away from the clearance area 1122 in the first direction X, thereby improving the connection reliability of the shielding layer 142 and the adhesive layer 141.
[0070] In some embodiments, such as Figure 4 , Figure 5 and Figure 7 As shown, the adhesive layer 141 includes a first part 1411 and a second part 1412 that are connected to each other. The first part 1411 and the shielding layer 142 are connected to the side surface of the shielding layer 142 facing the clearance area 1122 in the first direction X. The second part 1412 is disposed between the antenna body 1121 and the shielding layer 142 along the second direction Y, and / or, the second part 1412 is disposed between the antenna body 1121 and the shielding layer 142 along the third direction Z. The second part 1412 is used to insulate the antenna body 1121 and the shielding layer 142 from each other. The first direction X, the second direction Y and the third direction Z intersect each other.
[0071] In these embodiments, a second portion 1412 of an adhesive layer 141 is provided between the shielding layer 142 and the antenna body 1121, thereby improving the insulation reliability between the shielding layer 142 and the antenna body 1121.
[0072] See Figure 8 , Figure 8 for Figure 5 A magnified structural diagram at point D.
[0073] In some embodiments, such as Figure 4 , Figure 5 and Figure 8 As shown, a receiving groove 113 is provided on the surface of the clearance area 1122 on the side facing the screen structure 120 in the first direction X, and the shielding part 140 is disposed in the receiving groove 113.
[0074] Optionally, the shape of the receiving groove 113 matches the shape of the shielding part 140.
[0075] Optionally, the shielding part 140 is fully accommodated within the receiving groove 113 to reduce the blocking effect of the shielding part 140 on the radiation of the antenna body 1121 in the length and width directions of the electronic device 100.
[0076] Optionally, the shielding part 140 is bonded to the receiving groove 113 to improve the connection reliability between the shielding part 140 and the receiving groove 113; or the shielding part 140 is embedded in the receiving groove 113 to reduce the connection difficulty between the shielding part 140 and the receiving groove 113.
[0077] In these embodiments, a receiving groove 113 is provided on a portion of the surface of the clearance area 1122 facing the screen structure 120 in the first direction X, and the shielding part 140 is disposed in the receiving groove 113 to reduce the blocking effect of the shielding part 140 on the radiation of the antenna body 1121 in the length and width directions of the electronic device 100, which is beneficial to improving the communication effect of the electronic device 100.
