[0058] To make the objectives, technical solutions, and advantages of this application clearer, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0059] On the one hand, as shown in combination with Figure 1-3 This embodiment provides a screen - pressing assembly 100. The screen - pressing assembly 100 includes: a screen - pressing member 1 and an antenna radiator 2.

[0060] The screen - pressing member 1 is located on one side of the screen module 200 of the electronic device, is connected to the middle - frame structure 300 of the electronic device, and at least part of the screen - pressing member 1 extends above the screen module 200; the antenna radiator 2 is located on the side of the screen - pressing member 1 and / or is buried inside the screen - pressing member 1.

[0061] The pressing screen assembly 100 of this embodiment is applicable to an electronic device. The pressing screen member 1 is connected to the middle frame structure 300 and at least partially extends above the screen module 200 to press and protect the screen module 200. Since the pressing screen member 1 can be exposed outside the electronic device, the antenna radiator 2 arranged on the side or inside of the pressing screen member 1 has a good clearance environment and can have better radiation performance, so as to ensure that the electronic device can be used normally in both the unfolded state and the closed state.

[0062] Exemplarily, the electronic device is a foldable electronic device, and the screen module 200 has the characteristics of being flexible and foldable. The electronic device can be used in the closed state and the unfolded state.

[0063] In some possible implementation manners, the screen module 200 is an organic light-emitting diode display screen (Organic Light-Emitting Diode, OLED), including a display panel based on OLED technology.

[0064] Optionally, the structure of the display panel has various forms.

[0065] Exemplarily, the display panel includes a substrate, an organic light-emitting diode (Organic Light-Emitting Diode, OLED) layer, and a thin film encapsulation (Thin Film Encapsulation, TFE) layer that are sequentially stacked.

[0066] Another exemplarily, the display panel includes a substrate, a thin film transistor (Thin Film Transistor, TFT) layer, an organic light-emitting diode (Organic Light-Emitting Diode, OLED) layer, a thin film encapsulation (Thin Film Encapsulation, TFE) layer, a touch layer, and a polarizer that are sequentially stacked.

[0067] It should be noted that the layer structure of the display panel is not limited to the two structure forms listed above. In the case of meeting the requirements of foldable display, the display panel can also adopt other layer structure forms.

[0068] A foldable electronic device generally includes two parts of the body, and the two parts of the body are rotatably connected through a rotating shaft device. The relative rotation of the two parts of the body realizes the switching between the unfolded state and the closed state of the foldable electronic device. However, due to the non-extensible structure of the screen module 200, during the rotation of the body, the edge of the screen module 200 will slightly expand and contract relative to the body. Therefore, in order to protect the edge of the screen module 200, a screen pressing member 1 is arranged at the edge of the screen module 200. The screen pressing member 1 uses the part extending above the screen module 200 to apply a downward pressure to the screen module 200 and can cover the gap (or expansion and contraction gap) at the edge of the screen module 200.

[0069] In some possible implementation manners, the screen pressing member 1 is made of an injection molding material.

[0070] Exemplarily, the injection molding material includes but is not limited to polyamide (also known as nylon, Nylon), polycarbonate (Polycarbonate, PC), fiberglass (Fiber Glass, FG), polyethylene (Polyethylene, PE), polyether (Polyether), polyethylene glycol terephthalate (Polyethylene Glycol Terephthalate, PET), polymethyl methacrylate (Polymethyl Methacrylate, PMMA), polypropylene (Polypropylene), polystyrene (Polystyrene, PS), polyvinyl chloride (Polyvinyl Chloride, PVC), and the like. Any one of the above materials or a combination of any several materials can be used to form this embodiment.

[0071] In addition, in order to prevent the screen pressing member 1 from applying too much pressure to the screen module 200, at least part of the screen pressing member 1 (i.e., the part in contact with the screen module 200) is made of a flexible material, and the remaining part can be made of a harder injection molding material.

[0072] Combined Figure 1 As shown, in some embodiments, the antenna radiator 2 is located on the inner side surface of the screen pressing member 1 facing the screen module 200.

[0073] In this embodiment, the screen pressing member 1 is arranged at the edge of the screen module 200, and the inner side surface faces and wraps the side surface of the screen module 200 and does not directly contact the screen module 200 (because the screen module 200 needs to reserve a margin for expansion and contraction). When the antenna radiator 2 is located on the surface of the screen pressing member 1, arranging the antenna radiator 2 on the inner side surface of the screen pressing member 1 can not only ensure that the antenna radiator 2 has a good clearance environment, but also prevent the antenna radiator 2 from being exposed on the appearance side of the electronic device, affecting the aesthetics.

[0074] In some possible implementation manners, the inner side surface of the screen pressing member 1 can be understood as the surface that cannot be directly observed from the outside when the screen pressing member 1 is applied to the electronic device scenario. Refer to Figure 3 As shown, the inner side surface of the screen pressing member 1 is the side surface and the entire surface of the screen pressing member 1 facing the screen module 200, and the surface facing the inner cavity of the middle frame structure 300.

[0075] In some other possible implementation manners, the antenna radiator 2 is conformal designed with the inner side surface of the screen pressing member 1, and the antenna radiator 2 is designed to have the same spatial form as the inner side surface of the screen pressing member 1. For example, if the inner side surface of the screen pressing member 1 is a flat surface, the antenna radiator 2 is designed as a flat plate. If the inner side surface of the screen pressing member 1 is an arc surface, the antenna radiator 2 is designed as an arc.

[0076] In some embodiments, the antenna radiator 2 is a conductive branch structure formed on the inner side surface of the screen pressing member 1.

[0077] Through the above arrangement, the conductive branch structure directly formed on the inner side surface of the screen pressing member 1 by using printing processes, LDS (Laser Direct Structuring), spraying processes, brushing processes, pasting processes, etc. has the advantages of simple structure and convenient processing, and will not affect the screen pressing member 1, the screen module 200, the middle frame structure 300, etc.

[0078] Exemplarily, a film-shaped conductive branch structure is formed on the inner side surface of the screen pressing member 1 in the form of silver paste printing.

[0079] In some embodiments, a protective film layer is provided on the surface of the antenna radiator 2.

[0080] Considering the risk of scratching and damage to the conductive branch structure formed on the inner side surface of the screen pressing member 1, a protective film layer is provided on the surface of the antenna radiator 2 to protect the conductive branch structure serving as the antenna radiator 2.

[0081] In some possible implementation manners, the material of the protective film includes one or more of polyethersulfone (PES), polyacrylate, polyetherimide (PEI), polyethylene naphthalate two formic acid glycol ester (PEN), polyethylene glycol terephthalate (PET), polyphenylene sulfide (PPS), polyimide (PI), polycarbonate (PC), and cellulose acetate propionate (CAP).

[0082] Combined Figure 2 As shown, in some embodiments, the antenna radiator 2 is a conductive branch structure embedded inside the screen pressing member 1.

[0083] In this embodiment, the screen pressing member 1 is an injection molding structure, and a conductive branch structure is embedded inside the injection molding structure. The injection molding material has insulating properties. Therefore, the conductive branch structure can receive or emit electromagnetic waves through the external injection molding material, meeting the scenario requirements of the antenna system.

[0084] In addition, the conductive branch structure embedded inside the screen pressing member 1 can also enhance the strength of the screen pressing member 1 and improve the screen pressing protection effect of the screen pressing member 1.

[0085] Combined Figure 4 、 5 As shown, in some embodiments, the antenna radiator 2 includes a grounding branch 21 and a radiation branch 22. The grounding branch 21 is electrically connected to the middle frame structure 300, and the radiation branch 22 extends in a direction away from the middle frame structure 300.

[0086] The antenna radiator 2 of this embodiment includes a grounding branch 21 and a radiation branch 22. The grounding branch 21 is used for the grounding connection of the antenna radiator 2, and the radiation branch 22 is used for receiving or emitting electromagnetic waves. Among them, the radiation branch 22 extends in a direction away from the middle frame structure 300, which is beneficial to obtaining a better clearance environment. The grounding branch 21 extends towards the middle frame structure 300 and is electrically connected to the middle frame structure 300, enabling electrical grounding to be directly achieved through the middle frame structure 300. The grounding solution is simple and convenient to operate.

[0087] In some possible examples, when the pressing screen member 1 is in a connected state with the middle frame structure 300, the grounding stub 21 is in abutting connection with the middle frame structure 300. When the pressing screen member 1 is in a separated state from the middle frame structure 300, the grounding stub 21 is disconnected from the middle frame structure 300. Thus, while the pressing screen member 1 is assembled and connected to the middle frame structure 300, the connection between the grounding stub 21 and the middle frame structure 300 can be achieved, further simplifying the use and assembly efficiency of the pressing screen assembly 100.

[0088] Among them, the shape of the radiation stub 22 can be rectangular, square, circular, elliptical, spiral, wavy, zigzag, etc.

[0089] Combined with Figure 4 、 5 As shown, in some embodiments, the pressing screen assembly 100 further includes a feeding stub 23, and the feeding stub 23 is electrically connected to the radiation stub 22.

[0090] The feeding of the antenna radiator 2 can be achieved by using the feeding stub 23, and the reception and transmission of electromagnetic waves can be realized.

[0091] Combined with Figure 3 、 5 As shown, in some embodiments, the number of the antenna radiators 2 is at least two, and the at least two antenna radiators 2 are arranged in an array.

[0092] Through the above arrangement, at least two antenna radiators 2 form an antenna array on the inner side surface of the pressing screen member 1. Compared with a single antenna radiator 2, the antenna array has better radiation performance and working bandwidth, which is beneficial to improving the wireless communication performance of the electronic device.

[0093] Exemplarily, the antenna radiator 2 can be used for the transmission and reception of signals in the 5G millimeter wave band (30 - 300 GHz).

[0094] Thus, in this embodiment, an array antenna is constructed on the pressing screen member 1, which is exemplarily a millimeter wave array antenna. Thus, the antenna structure on the pressing screen assembly 100 of this embodiment has advantages such as high gain, high directivity, and high sensitivity.

[0095] Since the wavelength in the millimeter wave band is very short, the distance between the antenna radiators 2 can be very small, so that a high-density array layout of the antenna radiators 2 on the pressing screen member 1 can be achieved. At the same time, in this embodiment, the beamforming and direction control of signals can also be achieved by changing the phase and amplitude of the antenna unit, thereby improving the signal reception and transmission efficiency.

[0096] Combined with Figure 3 As shown, in some embodiments, at least two antenna radiators 2 are arranged in a linear array, and the array direction is parallel to the edge of the screen module 200.

[0097] Since the pressing screen member 1 needs to be arranged along the edge of the screen module 200 to cover the edge of the screen module 200, the main body of the pressing screen member 1 is strip-shaped. Therefore, at least two antenna radiators 2 are designed as a linear array, which can make full use of the surface space of the pressing screen member 1 and increase the number of array elements of the antenna radiator 2.

[0098] Combined with Figure 5 As shown, in some embodiments, the radiation branches 22 of the two antenna radiators 2 located at both ends of the linear array are electrically connected to the feeding branches 23 respectively.

[0099] Thus, the antenna array where the antenna radiator 2 of this embodiment is located can be equivalent to Figure 6 the equivalent circuit shown, where SRC1 and SRC2 are two feeding signal sources, which are respectively connected to the two feeding branches 23. The inductors L0, L1, and L2 are the equivalent inductors of each antenna radiator 2. N represents the number of inductors, which is not limited to the three shown in the figure and can be more. The capacitors C and C0 are the coupling capacitors between two adjacent antenna radiators 2; the inductor L3 and the capacitor C1 are the equivalent LC circuit of the grounding branch 21.

[0100] In this equivalent circuit, each antenna radiator 2 corresponds to an equivalent circuit unit. In each equivalent circuit unit, the capacitor C and the inductor L2 are in series, and then in parallel with the LC circuit composed of the capacitor C1 and the inductor L3 to form an equivalent circuit unit. The number of equivalent circuit units is the same as the number of antenna radiators 2 in the antenna array.

[0101] Combined with Figure 7 As shown, in some embodiments, the size of the antenna radiator 2 in the first direction a is d1, and the size in the second direction b is d2, where the value range of d1 is 0.5 - 1.5 mm, and the value range of d2 is 1.1 - 2.1 mm; wherein, the first direction a is perpendicular to the second direction b, and one of the first direction a and the second direction b is parallel to the surface of the screen module 200, and the other is perpendicular to the surface of the screen module 200.

[0102] When the size of the antenna radiator 2 meets the above value range, the antenna radiator 2 can achieve good operation within 50 GHz - 80 GHz, meeting the wireless communication requirements of the electronic device.

[0103] Exemplarily, the first direction a is parallel to the surface of the screen module 200 and is arranged along the length direction of the pressing screen member 1, and the second direction b is perpendicular to the surface of the screen module 200, that is, the thickness direction of the electronic device.

[0104] In some possible implementations, the value of d1 is, for example, 0.5 mm, 0.7 mm, 0.9 mm, 1.0 mm, 1.2 mm, 1.3 mm, 1.5 mm, etc. Optionally, the value of d1 is 1.0 mm.

[0105] In some other possible implementations, the value of d2 is, for example, 1.1 mm, 1.3 mm, 1.5 mm, 1.6 mm, 1.8 mm, 2.0 mm, 2.0 mm, etc. Optionally, the value of d2 is 1.6 mm.

[0106] Combined with Figure 7 As shown, in some embodiments, when the antenna radiator 2 is arranged in an array, the spacing between adjacent antenna radiators 2 is d3, and the value range of d3 is 0.05 - 0.15 mm.

[0107] When the size of the antenna radiator 2 meets the above value range, the antenna radiator 2 can achieve good operation within 50 GHz - 80 GHz, meeting the wireless communication requirements of the electronic device.

[0108] In some possible implementations, the value of d3 is, for example, 0.05 mm, 0.07 mm, 0.09 mm, 0.1 mm, 0.12 mm, 0.13 mm, 0.15 mm, etc. Optionally, the value of d3 is 0.1 mm.

[0109] Combined with Figure 7 As shown, in some embodiments, the antenna radiator 2 includes a grounding stub 21, and the length of the grounding stub 21 is d4, and the value range of d4 is 0.2 - 0.8 mm.

[0110] When the size of the antenna radiator 2 meets the above value range, the antenna radiator 2 can achieve good operation within 50 GHz - 80 GHz, meeting the wireless communication requirements of the electronic device.

[0111] In some possible implementations, the value of d4 is, for example, 0.2 mm, 0.3 mm, 0.5 mm, 0.7 mm, 0.8 mm, etc. Optionally, the value of d4 is 0.5 mm.

[0112] Combined with Figure 1 、 5 As shown, in some embodiments, the screen pressing member 1 includes a connecting portion 11, an extending portion 12, and a screen pressing portion 13; the connecting portion 11 is used to connect the middle frame structure 300, the extending portion 12 is connected to the connecting portion 11, the screen pressing portion 13 is connected to the extending portion 12, and the screen pressing portion 13 extends above the screen module 200.

[0113] With the above arrangement, the screen pressing member 1 uses the connecting portion 11 to connect to the middle frame structure 300, and uses the screen pressing portion 13 to press and protect the screen module 200.

[0114] Exemplarily, referring to Figure 5 , a connecting groove 3 for accommodating the connecting portion 11 is provided at the top of the middle frame structure 300, and the connecting portion 11 is inserted into the connecting groove 3 to realize the connection between the screen pressing member 1 and the middle frame structure 300.

[0115] In some possible implementation manners, referring to Figure 1 , 4 , as shown in FIG. 5, the inner side surface of the screen pressing member 1 is formed by the surface of the extending portion 12 and the screen pressing portion 13, and this inner side surface presents an arc surface structure. Optionally, the antenna radiator 2 located on this inner side surface is designed as a bent stub corresponding to this inner side surface. Using this bent stub as the antenna radiator 2 helps to improve the working performance of the antenna radiator 2.

[0116] Exemplarily, referring to Figure 11 , the electronic device includes a screen pressing assembly 100 arranged symmetrically up and down. The antenna radiators 2 in the two screen pressing assemblies 100 are both constructed as bent stubs bent toward the side where the screen module 200 is located. The upper and lower antenna radiators 2 can affect each other to generate an ultra-wideband effect, so that the coverage frequency range of the antenna array of the electronic device is as high as 50 GHz - 80 GHz, the average in-band efficiency reaches above -4.5 dB, and it has a working performance with a pattern scanning range of ±30°.

[0117] Figure 8 FIG. 21 is an S11 schematic diagram of the antenna array formed by the antenna radiator 2 in this embodiment, where the abscissa Frequency represents frequency, the unit is GHz, and the ordinate is gain, the unit is dB. From the figure, within the antenna frequency band of 50 GHz - 80 GHz, the S11 of the antenna array is lower than -6 dB, indicating that the antenna array has a small return loss and high working efficiency.
