electronic devices

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on August 31, 2023, with application number 202311137233.1 and invention name “Electronic Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of electronic products, and in particular to an electronic device. Background Art

[0003] Static electricity can easily accumulate on the screen surface of electronic devices during use (for example, when using them in winter or rubbing the screen). This static electricity can then be released into the device and hit the screen cables. Consequently, static electricity can cause the screen to malfunction and reduce its lifespan.

[0004] Summary of the Invention

[0005] The present application provides an electronic device that aims to at least to some extent solve the problem of a screen not functioning properly due to static electricity, while also being beneficial in improving the radiation efficiency of an antenna.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] The electronic device provided by the present application includes: a screen, a first frame, and an electrostatic discharge structure. The screen includes a first screen portion, the first screen portion having a first display surface, the first display surface including a first display area and a first non-display area, the first non-display area being located on the periphery of the first display area and connected to the first display area, and the first non-display area including a first area segment; the first frame is located on the side toward which the outer peripheral side surface of the first screen portion faces, the first frame including a first frame segment, the first frame segment being used to form at least one antenna radiator, and the first area segment being located between the first frame segment and the first display area; the electrostatic discharge structure is located on the side toward which the first area segment faces, and the electrostatic discharge structure includes a plurality of conductive portions, the plurality of conductive portions being spaced apart in the direction in which the first area segment extends.

[0008] In the electronic device of the embodiment of the present application, static electricity on the screen surface can be discharged to a reference ground through the electrostatic discharge structure without hitting the screen cable, which is beneficial for improving the service life of the screen. In addition, although a portion of the electromagnetic waves radiated by the antenna radiator may reach the electrostatic discharge structure, because the electrostatic discharge structure is defined by multiple spaced-apart conductive portions, this facilitates breaking the originally long electrostatic discharge structure into multiple relatively short conductive portions, making it difficult to form a reverse current on the shorter conductive portions. This can at least to some extent reduce or avoid the reflection of electromagnetic waves caused by the shorter conductive portions, which helps the electromagnetic waves bypass the shorter conductive portions and radiate to the outside world, thereby at least to some extent improving the radiation efficiency of the antenna.

[0009] Illustratively, the plurality of conductive portions define an electrostatic discharge structure.

[0010] For example, the material of the electrostatic discharge structure can be silver, copper, graphite or conductive cloth, so as to improve the electrostatic conduction effect.

[0011] In one possible implementation of the present application, in a conductive portion parallel to the first display surface and in the alignment direction of the first region and the first frame segment, opposite the antenna radiator, at least one conductive portion has a length less than twice the length of the corresponding antenna radiator. This further reduces or avoids reflection of electromagnetic waves by the shorter conductive portion, facilitating electromagnetic waves to radiate outwards by bypassing the shorter conductive portion, thereby further improving the antenna's radiation efficiency.

[0012] In one possible implementation of the present application, in a conductive portion parallel to the first display surface and in the alignment direction of the first region and the first frame segment, opposite the antenna radiator, at least one conductive portion is shorter than the corresponding antenna radiator. This further reduces or avoids reflection of electromagnetic waves by the shorter conductive portion, facilitating electromagnetic waves to radiate outwards by bypassing the shorter conductive portion, thereby further improving the antenna's radiation efficiency.

[0013] In one possible implementation of the present application, parallel to the first display surface and in the alignment direction of the first region and the first frame segment, the length of the conductive portion opposite the antenna radiator is shorter than the length of the corresponding antenna radiator. This further reduces or avoids reflection of electromagnetic waves by the shorter conductive portion, facilitating electromagnetic waves to radiate outwards by bypassing the shorter conductive portion, thereby further improving the antenna's radiation efficiency.

[0014] In one possible implementation of the present application, the number of conductive portions opposing the antenna radiator, parallel to the first display surface and in the arrangement direction of the first region segment and the first frame segment, ranges from 2 to 5. This further improves the antenna's radiation efficiency while simplifying the processing of the electrostatic discharge structure.

[0015] In one possible implementation of the present application, the first bezel has a first end face that is aligned with the first display surface. The electronic device further includes a first insulating frame that is located on the side facing the first end face and is fixedly connected to the first bezel. The first insulating frame includes a first cover portion that is laminated and disposed on the side facing the first non-display area, and the electrostatic discharge structure is laminated and fixedly attached to the surface of the first cover portion that faces the first area. This allows the first insulating frame to obscure the gap between the first screen portion and the first bezel, thereby optimizing the appearance of the electronic device.

[0016] For example, the electrostatic discharge structure can be a coating or plating layer attached to the surface of the first cover portion, so that the thickness occupied by the electrostatic discharge structure is relatively small.

[0017] In one possible implementation of the present application, the first insulating frame further includes a first side portion, the first side portion being located on the side toward which the outer peripheral side surface of the first screen portion faces, one end of the first side portion being connected to the first cover portion, and a positioning step being formed at an inner end of the first end surface, with the other end of the first side portion engaging with the positioning step. This facilitates improved assembly efficiency between the first insulating frame and the first side frame.

[0018] In one possible implementation of the present application, at least one of the multiple conductive parts is a first conductive part; the first insulating frame also includes a first side portion, the first side portion is located on the side facing the outer peripheral side of the first screen portion, one end of the first side portion is connected to the first cover portion, and the other end of the first side portion is matched with the first end surface. An electrostatic conductor is provided on the first side portion, and at least a portion of the electrostatic conductor is located on the surface of the first side portion facing the outer peripheral side of the first screen portion. One first conductive part corresponds to one electrostatic conductor, and the corresponding first conductive part is fixed to and electrically connected to the electrostatic conductor. In this way, the provision of the electrostatic conductor facilitates the first conductive part to discharge static electricity to a reference ground through the electrostatic conductor.

[0019] In a possible implementation of the present application, a portion of the electrostatic conductor is located on the surface of the outer peripheral side of the first side portion facing the first screen portion, and the remaining portion of the electrostatic conductor is located on the end surface of the first side portion facing away from the first display surface. This is beneficial to improving the reliability of the electrostatic conductor in discharging static electricity to the reference ground. In a possible implementation of the present application, a positioning step portion is formed at the inner end of the first end surface, and the other end of the first side portion cooperates with the positioning step portion; the portion of the positioning step portion located on the antenna radiator is a connecting portion, and the electrostatic conductor and the connecting portion are directly opposite to each other in the thickness direction of the first screen portion and are electrically connected. Therefore, the connecting portion can be used as part of the electrostatic discharge path, which is beneficial to using the connecting portion to discharge static electricity to the reference ground, thereby achieving the purpose of shortening the electrostatic discharge path.

[0020] In one possible implementation of the present application, the electrostatic conductor includes a first-type electrostatic conductor, the connection portion includes a grounding point, and the grounding point is directly opposite the first-type electrostatic conductor in the thickness direction of the first screen portion. The electronic device includes a first midplane, the first frame is fixed to the outer peripheral edge of the first midplane, and the first midplane includes a conductive portion, the conductive portion is fixed and electrically connected to the grounding point, and the conductive portion serves as a reference ground. In this way, static electricity on the first-type conductive portion, which is fixed and electrically connected to the first-type electrostatic conductor, can be discharged to the reference ground through the first-type electrostatic conductor and the grounding point in sequence, resulting in a relatively short static discharge path.

[0021] In one possible implementation of the present application, the first midplane further includes an insulating portion, which is fixed and directly connected between the conductive portion and the connection portion. The electronic device further includes a grounding connector, which is disposed within the insulating portion and fixed and electrically connected between the conductive portion and the grounding point. The grounding connector has a dimension in the direction of extension of the first section that is smaller than the dimension of the corresponding antenna radiator in the direction of extension of the first section. This allows, on the one hand, the insulating portion to separate the antenna radiator from the conductive portion, thereby satisfying clearance requirements for the antenna radiator. On the other hand, the grounding connector can also be used to ground the antenna radiator. Furthermore, the dimension of the grounding connector in the direction of extension of the first section is smaller than the dimension of the corresponding antenna radiator in the direction of extension of the first section, thereby facilitating antenna radiation efficiency.

[0022] In a possible implementation of the present application, the insulating portion wraps around the ground connector, which is beneficial for isolating the ground connector from other structures using the insulating portion, thereby improving the electrical connection reliability of the electronic device.

[0023] In a possible implementation of the present application, the electrostatic conductor includes a second type of electrostatic conductor; the connecting portion has a feeding point, and the feeding point is directly opposite to the second type of electrostatic conductor in the thickness direction of the first screen portion; the electronic device also includes a circuit board, a radio frequency chip, a feeding structure, and an electronic device, the circuit board has a grounded metal layer, the radio frequency chip and the electronic device are both fixed to the circuit board, the radio frequency chip and the electronic device are connected in parallel between the feeding structure and the grounded metal layer, and the feeding structure and the feeding point are fixed and electrically connected. The electronic device is an inductor, and the inductance of the inductor ranges from 1nH to 100nH; and / or the electronic device is an electrostatic protection device. In this way, when static electricity is discharged from the second type of electrostatic conductor to the feeding point, the static electricity can be discharged to the grounded metal layer via the electronic device, and at the same time, the radiation efficiency of the antenna will not be deteriorated.

[0024] In a possible implementation of the present application, the electrostatic protection device is a varistor or a transient voltage suppression diode.

[0025] In one possible implementation of the present application, the first conductive portion includes a first sub-conductive portion and a second sub-conductive portion. The first sub-conductive portion extends in the direction of extension of the first segment and is spaced apart from the corresponding electrostatic conductor. The second sub-conductive portion is fixed and electrically connected between the corresponding electrostatic conductor and the first sub-conductive portion. This facilitates electrical connection between the first conductive portion and the electrostatic conductor and also provides a shorter static discharge path between the first sub-conductive portion and the electrostatic conductor.

[0026] For example, the second sub-conductive portion and the first sub-conductive portion are formed as an integral part, which is helpful in simplifying the processing technology between the two and reducing manufacturing costs.

[0027] In one possible implementation of the present application, the size of the electrostatic conductor in the extension direction of the first region is smaller than or equal to the size of the corresponding second sub-conductive portion in the extension direction of the first region, thereby reducing the impact of the electrostatic conductor on the radiation efficiency of the antenna.

[0028] In one possible implementation of the present application, the size of the second sub-conductive portion in the extension direction of the first region is smaller than the size of the first sub-conductive portion in the extension direction of the first region, thereby reducing the impact of the second sub-conductive portion on the radiation efficiency of the antenna.

[0029] Illustratively, the ratio of the size of the second sub-conductive portion in the extending direction of the first regional segment to the size of the first sub-conductive portion in the extending direction of the first regional segment is greater than 0 and less than or equal to 0.5. For example, the ratio of the size of the second sub-conductive portion in the extending direction of the first regional segment to the size of the first sub-conductive portion in the extending direction of the first regional segment is 0.1, 0.15, 0.18, 0.2, 0.22, 0.25, 0.28, 0.3, 0.32, 0.35, 0.38, or 0.4.

[0030] In one possible implementation of the present application, at least one of the remaining conductive portions, other than the first conductive portion, is a second conductive portion, which is spaced apart from the electrostatic conductor. The provision of the second conductive portion facilitates designing the positions of the first and second conductive portions based on the structural layout of the electronic device, thereby optimizing the electrostatic discharge path of the electrostatic discharge structure.

[0031] In one possible implementation of the present application, in the extension direction of the first region, a first conductive portion adjacent to the second conductive portion is disposed on at least one side of the second conductive portion, thereby facilitating the discharge of static electricity from the second conductive portion to the first conductive portion.

[0032] In a possible implementation of the present application, there are multiple first conductive parts and multiple second conductive parts, and the first conductive parts and the second conductive parts are alternately arranged in the extension direction of the first region segment.

[0033] In one possible implementation of the present application, an air gap is formed between the second conductive portion and the first conductive portion adjacent to the second conductive portion. The air gap is configured to couple the two conductive portions and electrically connect them. This design ensures the conduction of static electricity without affecting the radiation efficiency of antenna 80. Furthermore, it has a simple structure and is easy to manufacture.

[0034] In a possible implementation of the present application, the size of the air gap is less than 0.5 mm, which is conducive to ensuring the reliability of the coupling and feeding between the first conductive part and the second conductive part.

[0035] Specifically, the size of the air gap is less than 0.05 mm. Exemplarily, the size of the air gap is 0.035 mm, 0.038 mm, 0.04 mm, 0.042 mm, 0.045 mm or 0.048 mm.

[0036] In one possible implementation of the present application, the second conductive portion and the first conductive portion adjacent to the second conductive portion are electrically connected via an inductor structure, and the inductance of the inductor structure ranges from 1nH to 100nH. In this way, the inductor structure with an inductance range of 1nH to 100nH is close to a short circuit for static electricity, but close to an open circuit for the antenna. When static electricity accumulates at the second conductive portion, the static electricity can be discharged through the second conductive portion to the first conductive portion closest to the second conductive portion, which can ensure the discharge of static electricity without affecting the radiation efficiency of the antenna.

[0037] Exemplarily, the inductance of the inductor structure is 10nH, 20nH, 30nH, 40nH, 50nH, 60nH, 70nH, 80nH, or 90nH.

[0038] In one possible implementation of the present application, an electronic device includes an antenna, the antenna includes an antenna radiator, the antenna operates at a frequency of 1.5 GHz to 6 GHz, and the inductance of the inductor structure is 1 to 20 nH. This ensures the antenna's radiation efficiency while improving the reliability of the inductor structure in conducting electrostatic discharges.

[0039] In a possible implementation of the present application, the inductor structure is an inductor, which has a simple structure and low cost.

[0040] In one possible implementation of the present application, the inductor structure is a metal serpentine wire. This helps reduce the thickness of the inductor structure itself, thereby reducing the thickness of the electronic device and achieving a compact structure of the electronic device. In addition, the structure is simple, easy to process and manufacture, and low in cost.

[0041] For example, the metal serpentine wire and the electrostatic discharge structure can be made of the same material. This allows the metal serpentine wire and the electrostatic discharge structure to be processed from the same material, thereby improving the reliability of the electrical connection between the two. Of course, it is understood that in other examples, the metal serpentine wire and the electrostatic discharge structure can also be made of different materials.

[0042] In one possible implementation of the present application, the inductor structure is a metal serpentine wire fixed to the first cover portion, and the metal serpentine wire and the conductive portion connected to the metal serpentine wire are formed as an integral part. This simplifies the processing between the electrostatic discharge structure and the metal serpentine wire, improving processing efficiency and enhancing the reliability of the connection between the metal serpentine wire and the electrostatic discharge structure.

[0043] In one possible implementation of the present application, the second conductive portion and the first conductive portion adjacent to the second conductive portion are electrically connected via an electrostatic protection device. This ensures the antenna's radiation efficiency while also dissipating static electricity from the second conductive portion to the first conductive portion.

[0044] In a possible implementation of the present application, the electrostatic protection device is a varistor or a transient voltage suppression diode, thereby increasing the reliability of electrostatic discharge.

[0045] In a possible implementation of the present application, the electronic device further includes a screen cable and a sealing foam. One end of the screen cable is connected to the portion of the outer peripheral side surface of the first screen portion facing the first frame segment, and the sealing foam is fixed to the first cover portion and abuts against the first non-display area; or, the sealing foam is fixed to the first non-display area and abuts against the first cover portion. In this way, on the one hand, the provision of the sealing foam can facilitate the relative movement between the screen and the first insulating frame, and at the same time, the sealing foam can also play a certain waterproof role, thereby improving the working reliability of the screen cable; on the other hand, when one end of the screen cable is connected to the portion of the outer peripheral side surface of the first screen portion facing the first frame segment, the screen cable is relatively close to the electrostatic discharge structure, thereby improving the electrostatic protection effect of the screen cable.

[0046] In a possible implementation of the present application, the screen also includes a second screen part and a third screen part, and the third screen part is connected between the first screen part and the second screen part; the electronic device includes a first shell, a second shell and a rotating mechanism, the rotating mechanism is connected between the first shell and the second shell, and the first shell and the second shell are configured to rotate relative to each other through the rotating mechanism; the first shell is used to support and fix the first screen part, the second shell is used to support and fix the second screen part, and the rotating mechanism is used to support the third screen part; wherein, the first shell includes a first middle plate, a first insulating frame and a first frame segment, and the first frame segment is located at the end of the first shell away from the second shell.

[0078] The specific structure of the electronic device of the present application will be described in detail below with reference to the accompanying drawings.

[0079] An embodiment of the present application provides an electronic device. The electronic device is a type of electronic device having an antenna. Specifically, the electronic device includes but is not limited to a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a personal computer, a notebook computer, a vehicle-mounted device, a wearable device, etc. Among them, wearable devices include but are not limited to smart watches, etc. Among them, the electronic device can be a foldable electronic device (for example, a foldable mobile phone). For a foldable electronic device, it can be unfolded to an unfolded state or folded to a folded state under different usage requirements. Of course, the electronic device can also be a non-foldable electronic device, such as a straight-screen mobile phone.

[0080] Please refer to Figure 1, which is a perspective view of an electronic device 100 in an unfolded state according to some embodiments of the present application. In this embodiment, the electronic device 100 is a foldable electronic device. Specifically, the electronic device 100 includes a screen 10, a support device 20, a circuit board (not shown in Figure 1), and an antenna (not shown in Figure 1).

[0081] It should be understood that FIG1 only schematically illustrates some components included in the electronic device 100 , and the actual shape, actual size, actual position and actual structure of these components are not limited by FIG1 .

[0082] The screen 10 has a display surface and a fixed surface facing each other. The display surface faces the outside of the electronic device 100. The screen 10 can display information through the display surface and provide an interactive interface for the user. In various embodiments of the present application, the screen 10 can be, but is not limited to, an organic light-emitting diode (OLED) display, an active-matrix organic light-emitting diode (AMOLED) display, or a quantum dot light-emitting diode (QLED) display.

[0083] The screen 10 can be switched between an unfolded state and a folded state. The screen 10 is fixed and supported on a support device 20 by a fixing surface. The support device 20 allows the screen 10 to be switched between the unfolded state and the folded state.

[0084] Specifically, referring to Figure 1 , screen 10 may include a first screen portion 11, a second screen portion 12, and a third screen portion 13. Third screen portion 13 is connected between first screen portion 11 and second screen portion 12. At least third screen portion 13 of screen 10 is made of a flexible material. First screen portion 11 and second screen portion 12 may be made of a flexible material, a rigid material, or partially rigid and partially flexible, without specific limitation herein.

[0085] Continuing with Figure 1, when screen 10 is in the unfolded state, first screen portion 11, second screen portion 12, and third screen portion 13 are coplanar and oriented in the same direction. In this state, a large-screen display can be achieved, providing users with richer information and a better user experience.

[0086] For ease of explanation, an XYZ coordinate system is established for the first screen portion 11. The thickness direction of the first screen portion 11 is defined as the Z-axis. Directions perpendicular to the Z-axis are the X-axis and Y-axis directions, respectively. The X-axis direction is the alignment direction of the end of the first screen portion 11 closest to the third screen portion 13 and the end of the first screen portion 11 farther from the third screen portion 13. The Y-axis direction is the direction in which the folding centerline of the screen 10 extends.

[0087] Please refer to Figure 2, which is a three-dimensional diagram of the electronic device 100 in a folded state according to Figure 1. When the screen 10 is in the folded state, the third screen portion 13 is in a bent state, and the first screen portion 11 and the second screen portion 12 are stacked. In this state, the screen 10 is not visible to the user, and the support device 20 is protected outside the screen 10 to prevent the screen 10 from being scratched by hard objects. This electronic device 100 is an inward-folding electronic device. In other examples, the foldable electronic device 100 can also be an outward-folding electronic device. For outward-folding electronic devices. In the folded state, the third screen portion 13 is in a bent state, the first screen portion 11 and the second screen portion 12 are stacked and spaced, and the support device 20 is between the first screen portion 11 and the second screen portion 12, and the screen 10 is on the outside of the support device 20.

[0088] Please refer to Figure 3, which is a perspective view of the electronic device 100 shown in Figure 1, with the screen 10 and support device 20 in a disassembled state. The display surface of the screen 10 generally includes a display area 14 and a non-display area 15. The non-display area 15 is arranged around the display area 14. To prevent light leakage from the display of the screen 10 when the screen 10 displays image information, the non-display area 15 is generally provided with a light-shielding layer (e.g., an ink layer) to prevent light leakage from the display area 14.

[0089] 3 , the display area 14 includes a first display area 141 on the first screen portion 11, a second display area 142 on the second screen portion 12, and a third display area 143 on the third screen portion 13. The third display area 143 is connected between the first display area 141 and the second display area 142.

[0090] The non-display area 15 includes a first non-display area 151 on the first screen portion 11, a second non-display area 152 on the second screen portion 12, and a third non-display area 153 on the third screen portion 13. The first non-display area 151 is located on the periphery of the first display area 141 and is connected to the first display area 141. The peripheral side surface J1 of the first screen portion 11 is connected between the edge of the first non-display area 151 and the fixed surface of the first screen portion 11. The second non-display area 152 is located on the periphery of the second display area 142 and is connected to the second display area 142. The peripheral side surface J2 of the second screen portion 12 is connected between the edge of the second non-display area 152 and the fixed surface of the second screen portion 12. The third non-display area 153 is connected between the first non-display area 151 and the second non-display area 152. The third non-display area 153 is located at both ends of the third display area 143 in the Y-axis direction. One of the third non-display areas 153 , the first non-display area 151 , another third non-display area 153 and the second non-display area 152 are sequentially connected to form a ring.

[0091] The first non-display area 151 and the first display area 141 collectively form the first display surface of the first screen portion 11. The second non-display area 152 and the second display area 142 collectively form the second display surface of the second screen portion 12. The third non-display area 153 and the third display area 143 collectively form the third display surface of the third screen portion 13.

[0092] Continuing with FIG3 , a section of the first non-display area 151 along its own extension path is a first segment 1511. That is, the first non-display area 151 includes the first segment 1511. The first segment 1511 is located on the side of the first display area 141 away from the second display area 142. Of course, it is understood that in other examples, the first segment 1511 may be located on both sides or one side of the first display area 141 in the Y-axis direction. Alternatively, a portion of the first segment 1511 may be located on the side of the first display area 141 away from the second display area 142, while another portion is located on one side of the first display area 141 in the Y-axis direction.

[0093] 2 and 3 , the supporting device 20 includes a first housing 21 , a second housing 22 and a rotating mechanism 23 .

[0094] It is understandable that FIG. 2 and FIG. 3 only schematically illustrate some components of the supporting device 20 , and the actual shape, actual size, actual position and actual structure of these components are not limited by FIG. 3 .

[0095] The first housing 21 is used to secure and support the first screen portion 11. Specifically, the first housing 21 has a first support surface M1. The securing surface of the first screen portion 11 faces the first support surface M1. The first screen portion 11 is stacked and secured to the first support surface M1. Exemplarily, the connection between the first support surface M1 and the first screen portion 11 includes, but is not limited to, gluing.

[0096] The second housing 22 is used to secure and support the second screen portion 12. Specifically, the second housing 22 has a second support surface M2. The securing surface of the second screen portion 12 faces the second support surface M2. The second screen portion 12 is stacked and secured to the second support surface M2. Exemplarily, the connection between the second support surface M2 and the second screen portion 12 includes, but is not limited to, gluing.

[0097] The rotating mechanism 23 is used to support the third screen portion 13. The rotating mechanism 23 has a third supporting surface M3. The rotating mechanism 23 can support the third screen portion 13 of the screen 10 through the third supporting surface M3.

[0098] The rotating mechanism 23 is connected between the first shell 21 and the second shell 22. The first shell 21 and the second shell 22 are configured to be rotatably connected through the rotating mechanism 23, thereby realizing the relative folding or relative unfolding of the first shell 21 and the second shell 22, and further realizing the folding or unfolding of the screen 10.

[0099] Specifically, referring to Figure 2 , in the folded state, the first and second shells 21, 22 are stacked and spaced apart. The first support surface M1 of the first shell 21 and the second support surface M2 of the second shell 22 face each other, concealing the screen 10 between the first and second shells 21, 22 and thus protecting the screen 10. Referring to Figure 3 , in the unfolded state, the first support surface M1 of the first shell 21, the second support surface M2 of the second shell 22, and the third support surface M3 of the rotating mechanism 23 are coplanar and oriented in the same direction. This ensures reliable support for the screen 10 and ensures its flatness.

[0100] The electronic device 100 provided in an embodiment of the present application can switch between an unfolded state and a folded state. When a user uses the electronic device 100 to browse web pages, information, videos, play games, etc., the electronic device 100 can be switched from the folded state to the unfolded state. Specifically, the first shell 21 and the second shell 22 can be rotated 90° in directions away from each other, so that the first shell 21 and the second shell 22 form a 180° angle. This can achieve a large-screen display, provide users with richer information, and give users a better user experience. When the user finishes using the electronic device 100, the electronic device 100 can be switched from the unfolded state to the folded state. Specifically, the first shell 21 and the second shell 22 can be rotated 90° in directions close to each other, so that the first shell 21 and the second shell 22 form a 0° angle. In this way, the volume of the electronic device 100 can be reduced, making it easier to store the electronic device 100. In the folded state, the screen 10 is invisible to the user, which can prevent the screen 10 from being scratched by hard objects.

[0101] It is worth noting that the specific structure of the rotating mechanism is well known to those skilled in the art and will not be described in detail here.

[0102] In addition, it can be understood that when the electronic device 100 is a non-foldable electronic device 100, the support device 20 can be defined only by the first housing 21. The screen 10 can be defined only by the first screen portion 11. In this case, the first non-display area 151 is provided around the first display area 141.

[0103] Please refer to FIG4 , which is an exploded schematic diagram of the supporting device 20 shown in FIG3 . The first housing 21 includes a first back cover 212 , a first middle frame 211 and a first insulating frame 213 .

[0104] Continuing with FIG4 , the first back cover 212 is in the shape of a flat plate. For example, the first back cover 212 is in the shape of a rectangular flat plate or a rounded rectangular flat plate. Of course, in other examples, the first back cover 212 can also be in the shape of a semicircular flat plate, a diamond-shaped flat plate, an oblong flat plate, an elliptical flat plate, or a special shape. The materials of the first back cover 212 include, but are not limited to, glass, plastic, and metal.

[0105] Please refer to FIG5 , which is a perspective view of the first middle frame shown in FIG4 . The first middle frame 211 includes a first middle plate 2111 and a first side frame 2112 .

[0106] The first middle plate 2111 and the first back cover 212 are stacked and spaced apart in the Z-axis direction. Specifically, the shape of the first middle plate 2111 is adapted to the shape of the first back cover 212. The first middle plate 2111 has a first support surface M1.

[0107] The first mid-plane 2111 includes a conductive portion 21111 and an insulating portion 21112. The conductive portion 21111 serves as a reference ground. Each circuit element within the electronic device 100 can be grounded by being electrically connected to the reference ground, preventing leakage and damage to the circuit elements caused by high current surges.

[0108] On this basis, illustratively, the material of the first middle plate 2111 includes, but is not limited to, a combination of metal and plastic. The specific location of the reference ground is not limited to this in this application. In other examples, the first middle plate 2111 may not be used as a reference ground, but a portion of the first frame 21121 may be used as a reference ground, or the reference ground may be set directly on the circuit board. Exemplarily, the material of the conductive portion 21111 includes, but is not limited to, metal, such as copper, iron, or aluminum. The material of the insulating portion 21112 includes, but is not limited to, plastic.

[0109] The first side frame 2112 is disposed around the edges of the first middle plate 2111 and the first back cover 212 and is fixedly connected to the first middle plate 2111 and the first back cover 212 to define a first installation space (not shown in FIG5 ) with the first middle plate 2111 and the first back cover 212.

[0110] In some examples, the first side frame 2112 and the first middle plate 2111 are integrally formed. This improves the connection strength between the first side frame 2112 and the first middle plate 2111, simplifies the manufacturing process, and reduces assembly costs. In other examples, the connection between the first side frame 2112 and the first middle plate 2111 includes, but is not limited to, gluing, welding, clamping, or screwing. This configuration simplifies the mold structure of the first side frame 2112 and the first middle plate 2111, facilitating independent manufacturing of the first side frame 2112 and the first middle plate 2111.

[0111] In some examples, the connection between the first side frame 2112 and the first back cover 212 includes, but is not limited to, gluing, snapping, or screwing. This configuration can simplify the molds of the first side frame 2112 and the first back cover 212, facilitating independent processing and manufacturing of the first side frame 2112 and the first back cover 212.

[0112] The material of the first side frame 2112 includes but is not limited to metal, plastic, and a combination of the two.

[0113] Specifically, the first side frame 2112 includes a first side wall 21122 and a first side frame 21121 connected to the first middle plate 2111 in a circumferential direction.

[0114] The first side wall 21122 is connected between an edge of the first middle plate 2111 adjacent to the rotating mechanism 23 and an edge of the first back cover 212 adjacent to the rotating mechanism 23 , and faces the rotating mechanism 23 .

[0115] Please refer to Figure 6, which is a schematic diagram of the cooperation between the first middle frame 211 and the screen 10 shown in Figure 5. The first frame 21121 is on the side facing the outer peripheral side J1 of the first screen part 11. In other words, the outer peripheral side J1 of the first screen part faces the first frame 21121. The first frame 21121 is fixed to the outer peripheral edge of the first middle plate 2111 and is connected to the first back cover 212. In addition, the two ends of the first frame 21121 in the circumferential direction of the first middle plate 2111 are connected to the first side wall 21122. Thus, a closed first installation space is formed.

[0116] The first frame 21121 includes a first frame segment D1. The first frame segment D1 is located on the side of the first regional segment 1511 away from the first display area 141. That is, the first regional segment 1511 is between the first frame segment D1 and the first display area 141. Exemplarily, the first frame segment D1 is located at one end of the first shell 21 away from the second shell 22. It is understandable that in other examples, the first frame segment D1 can also be located at one or both ends of the first shell 21 in the Y-axis direction. Alternatively, a portion of the first frame segment D1 is located at one end of the first shell 21 away from the second shell, and the other portion is located at one end of the first shell 21 in the Y-axis direction. As long as it is ensured that the first frame segment D1 is located on the side of the first regional segment 1511 away from the first display area 141, it will be sufficient. Those skilled in the art can design the specific position of the first frame segment D1 according to actual needs, and this application does not make any specific restrictions on this.

[0117] The first frame segment D1 is used to form the antenna radiator of the antenna. Exemplarily, the first frame segment D1 can form one antenna radiator or multiple antenna radiators. When the first frame segment D1 forms multiple antenna radiators D11, the multiple first frame segments D1 include multiple sub-segments. Each sub-segment is used to form an antenna radiator D11. At this time, the multiple antenna radiators D11 are spaced apart along the extension trajectory of the first frame segment D1 itself, and a gap is formed between two adjacent antenna radiators D11. The gap can be filled with an insulating structure D12. Exemplarily, the material of the insulating structure D12 includes but is not limited to plastic.

[0118] The insulating portion 21112 of the first middle plate 2111 is fixed and directly connected between the conductive portion 21111 and the first frame segment D1. In this way, the insulating portion 21112 can be used to separate the antenna radiator D11 from the conductive portion 21111, thereby meeting the clearance requirement of the antenna radiator D11.

[0119] For example, the insulating portion 21112 and the insulating structure D12 in the first frame segment D1 can be formed as an integral part, which is beneficial for improving the connection strength between the two.

[0120] The first frame 21121 has a first end surface F1 , the orientation of which is consistent with the orientation of the first display surface (ie, the first non-display area 151 and the first display area 141 ).

[0121] Please refer to Figures 7a and 7b. Figure 7a is a schematic diagram of a partial cross-sectional structure of the electronic device 100 shown in Figure 1 along line AA, and Figure 7b is an enlarged view of the circled portion at line P of the structure shown in Figure 7a. The first insulating frame 213 is located on the side facing the first end face F1, that is, the first end face F1 faces the first insulating frame 213. The first insulating frame 213 is fixed to the first frame 21121. The connection between the first insulating frame 213 and the first frame 21121 includes, but is not limited to, snap-fitting, gluing, or screwing.

[0122] Specifically, the first insulating frame 213 and the first frame 21121 extend in the same trajectory (see FIG4 ). In the specific example of the present application, the first insulating frame 213 and the first frame 21121 both extend in a substantially U-shaped manner.

[0123] The material of the first insulating frame 213 includes but is not limited to plastic.

[0124] Continuing with Figures 7a and 7b, the first insulating frame 213 includes a first cover portion 2131 and a first side portion 2132. The first cover portion 2131 is stacked on the side facing the first non-display area 151. In other words, the first cover portion 2131 is stacked on the side of the first non-display area 151 away from the first back cover 212.

[0125] The first side portion 2132 is located on the side facing the outer peripheral side J1 of the first screen portion 11. In other words, the outer peripheral side of the first screen portion 11 faces the first side portion 2132. One end of the first side portion 2132 is connected to the end of the first cover portion 2131 away from the center of the first display surface.

[0126] 7a, a positioning step F2 is formed at the inner end of the first end surface F1 to facilitate the positioning and installation between the first side portion 2132 and the first frame 21121. The other end of the first side portion 2132 is engaged with the positioning step F2.

[0127] In an embodiment of the present application, by providing the first insulating frame 213 , the first insulating frame 213 can be used to block the gap between the first screen portion 11 and the first border 21121 , thereby optimizing the appearance of the electronic device 100 .

[0128] Because antenna radiator D11 is a segment of the first frame 21121's extension, when the first end surface F1 of the first frame 21121 is provided with a positioning step F2, a portion of the positioning step F2 lies on antenna radiator D11. Therefore, the portion of the positioning step F2 that lies on antenna radiator D11 constitutes the connecting portion F3. In this case, the insulating portion 21112 is fixed and directly connected between the connecting portion F3 and the conductive portion 21111.

[0129] It is worth noting, referring back to Figure 4 , that the second housing 22 can include a second back cover 222, a second middle frame 221, and a second insulating frame 223. The specific structures of the second back cover 222, second middle frame 221, and second insulating frame 223 can be found in the previous description of the first housing 21 and will not be further described. In other words, the structure of the second housing 22 can be the same as that of the first housing 21. Of course, the structure of the second housing 22 can also differ from that of the first housing 21.

[0130] 7a, the circuit board 30 is located in the first installation space Q. Specifically, the circuit board 30 can be stacked and fixed to the first middle plate 2111. For example, the circuit board 30 can be fixed to the first middle plate 2111 by gluing, welding, clamping or screwing.

[0131] The circuit board 30 can be a rigid circuit board, a flexible circuit board, or a combination of rigid and flexible circuit boards. For example, the circuit board 30 can be made of FR-4 dielectric board, Rogers dielectric board, or a combination of FR-4 and Rogers dielectric board. FR-4 is a designation for a flame-retardant material grade, and Rogers dielectric board is a high-frequency board.

[0132] In order to facilitate the circuit board 30 to control the screen 10 to display images or information, etc., please continue to refer to FIG. 7 a , the electronic device 100 further includes a screen cable 90 . The screen cable 90 is used to electrically connect the screen 10 and the circuit board 30 .

[0133] Specifically, one end of the screen cable 90 is connected to the portion of the outer peripheral side J1 of the first screen portion 11 facing the first frame segment D1, the screen cable 90 is passed through the first middle plate 2111, and the other end of the screen cable is fixed to and electrically connected to the circuit board 30.

[0134] In some examples, the screen cable 90 is a flexible printed circuit (FPC). This facilitates bending of the screen cable 90 and reduces the difficulty of assembling the screen cable 90 with the circuit board 30. In other examples, the screen cable 90 can also be an enameled wire.

[0135] Specifically, the circuit board 30 includes a grounding metal layer (not shown). The grounding metal layer is electrically connected to the reference ground on the first midplane 2111. For example, referring to FIG. 7a , the grounding metal layer 301 and the first midplane 2111 can be fixed and electrically connected via a metal spring 40.

[0136] Please refer to Figure 8, which is a schematic cross-sectional view of the circuit board 30 shown in Figure 7a. Circuit board 30 includes multiple metal layers 301 and multiple insulating dielectric layers 302. The metal layers 301 and insulating dielectric layers 302 are alternately stacked along the thickness direction (i.e., the Z-axis) of circuit board 30, thereby forming a multi-layer wiring structure.

[0137] In some embodiments, the circuit board 30 further includes a solder resist layer 303 disposed on the surface of the multi-layer wiring structure. Specifically, one layer of the multi-layer metal layer 301 can be used as a ground metal layer.

[0138] For example, to facilitate electrical connection between the ground metal layer and the reference ground of the first mid-board 2111, the ground metal layer can be the metal layer 301 closest to the first mid-board 2111 among the multiple metal layers 301. Of course, the ground metal layer can also be another metal layer 301 in the circuit board 30.

[0139] Referring to Figure 9 , and in conjunction with Figure 7a , Figure 9 is a perspective view illustrating the relative positional relationship between a portion of the first frame segment D1 and the circuit board 30 in the electronic device 100 shown in Figure 7a . The circuit board 30 is used to integrate a control chip. Specifically, a radio frequency chip 70 may be fixed to the circuit board 30 .

[0140] The antenna 80 is electrically connected to the RF chip 70 on the circuit board 30 to transmit the RF signal from the RF chip 70 to the external space in the form of electromagnetic waves through the antenna radiator D11 to achieve signal transmission; or the antenna 80 receives electromagnetic waves from the external space through the antenna radiator D11, and converts the electromagnetic waves into RF signals and transmits them to the RF chip 70 to achieve signal reception.

[0141] In some embodiments, the RF chip 70 includes a transmitting path and a receiving path. The transmitting path includes components such as a power amplifier and a filter, which perform power amplification and filtering on the signal before transmitting it to the antenna radiator D11 and transmitting it to the outside world via the antenna 80. The receiving path includes components such as a low-noise amplifier and a filter, which perform low-noise amplification and filtering on the external signal received by the antenna 80 before transmitting it to the RF chip 70, thereby enabling signal communication between the electronic device 100 and the outside world through the RF chip 70 and the antenna 80.

[0142] Antenna 80 can be an omnidirectional antenna. An omnidirectional antenna radiates signals in all directions around the antenna 80, similar to a spherical transmitting source. This means that the signal radiation intensity is uniform in all directions around the antenna 80, achieving optimal communication. In other examples, antenna 80 can also be a directional antenna. A directional antenna radiates signals in a specific direction.

[0143] The operating frequency of the antenna 80 may be in the range of 0.5 GHz to 6 GHz. In other examples, the operating frequency of the antenna 80 may be higher or lower. This application does not impose any specific limitation on this.

[0144] Exemplarily, the antenna 80 can be a WiFi antenna, and the electronic device 100 can achieve short-range communication through the antenna 80 to achieve functions such as D2D (device-to-device communication), WiFi screen projection, and WiFi proximity discovery. The antenna 80 can operate in the 2.4G frequency band (frequency in the range of 2.4GHz to 2.5GHz) and / or the 5G frequency band (frequency in the range of 5GHz-6GHz) for WLAN communication. It can be understood that both the 2.4G frequency band and the 5G frequency band are used for short-range wireless communication technology. The 2.4G frequency band has a narrow bandwidth, low frequency, strong wall penetration ability, and a large communication range; the 5G frequency band has a wider bandwidth, high frequency, and fast transmission speed. The antenna 80 can select a suitable frequency band according to the working environment to adapt to a variety of application environments and improve the communication performance of the electronic device 100.

[0145] For example, the number of antennas 80 can be one or more. When there are multiple antennas 80, the multiple antennas 80 can operate independently or in combination. Each antenna 80 in the electronic device 100 can be used to cover a single or multiple communication frequency bands. Different antennas 80 can also be reused to improve the utilization of the antennas 80.

[0146] Please continue to refer to FIG. 9 and FIG. 7 a together. The antenna 80 includes the antenna radiator D11 , the feeding structure 81 and the reference ground (ie, the conductive portion 21111 ) mentioned above.

[0147] The antenna 80 may include an antenna radiator D11. The specific examples shown in Figures 1-9 illustrate an antenna 80 having a single antenna radiator D11. In other examples, the antenna 80 may include multiple antenna radiators D11. Referring again to Figure 9, the antenna radiator D11 has a feed point D111 and a ground point D112.

[0148] Specifically, the feeding point D111 and the grounding point D112 are both located on the connection portion F3. The feeding structure 81 is fixed and electrically connected to the feeding point D111, and the feeding structure 81 is electrically connected to the RF chip 70. The RF chip 70 feeds RF signals to the feeding point D111 of the antenna radiator D11 through the feeding structure 81, or receives external RF signals received by the antenna radiator D11. It should be noted that the feeding point D111 of the present application is not an actual point. The feeding point D111 refers to a position on the antenna radiator D11 that is in direct contact with and fixed to the feeding structure 81.

[0149] Exemplarily, the feed structure 81 includes, but is not limited to, metal connecting strips, feed springs, microstrip lines, and coaxial lines. For example, referring to FIG9 , the feed structure 81 includes a metal connecting block 811 and a feed spring 812. The metal connecting block 811 is fixed to the antenna radiator D11. One end of the feed spring 812 is fixed to the circuit board 30 and electrically connected to the RF chip 70. The other end of the feed spring 812 abuts the metal connecting block 811.

[0150] In other examples, the antenna radiator D11 and the RF chip 70 may be electrically connected directly without the aid of the feeding structure 81. In this case, the antenna 80 may not include the feeding structure 81. At this time, the feeding point D111 refers to the position on the antenna radiator D11 that is in direct contact with and fixed to the RF chip 70.

[0151] Referring to Figure 10 , and in conjunction with Figure 9 , Figure 10 is a perspective view illustrating the relative positional relationship between a portion of the first frame segment D1 and the first midplane 2111 in the electronic device 100 shown in Figure 7a . The antenna radiator D11 is electrically connected to the reference ground (i.e., the conductive portion 2111) at the grounding point D112. In some embodiments, the antenna 80 further includes a grounding connector 82. The grounding connector 82 may be disposed on the aforementioned insulating portion 21112. Furthermore, one end of the grounding connector 82 is fixedly secured and electrically connected to the grounding point D112 of the antenna radiator D11, while the other end of the grounding connector 82 is fixedly secured and electrically connected to the conductive portion 21111. In this manner, the antenna radiator D11 can be grounded. In other examples, the antenna 80 may also not include the grounding connector 82. It should be noted that, in this application, the grounding point D112 refers to the location on the antenna radiator D11 that is in direct contact with and fixed to the grounding connector 82. When the ground connector 82 is not provided, the ground point D112 refers to a position on the antenna radiator D11 that is used to directly contact and be fixed with the reference ground.

[0152] Considering the insulation between the ground connector 82 and other structures within the electronic device 100, as an example, referring to FIG. 10 and in conjunction with FIG. 7 a , the ground connector 82 can be embedded within the insulating portion 21112. In other words, the insulating portion 21112 encases the ground connector 82. The insulating portion 21112 thereby insulates the ground connector 82 from other structures, improving the electrical connection reliability of the electronic device 100.

[0153] On this basis, in order not to affect the radiation efficiency of the antenna 80 and to facilitate the feeding of the antenna radiator D11, the size of the grounding connector in the extension direction of the first area segment 1511 (that is, the extension direction of the first frame segment D1) is smaller than the size of the corresponding antenna radiator D11 in the extension direction of the first area segment 1511.

[0154] Please refer to Figure 11, which is a schematic diagram illustrating the screen 10 shown in Figure 3 transitioning between the folded and unfolded states. Because the screen 10 deforms when switching between the unfolded and folded states, relative sliding occurs between the screen 10 and the first insulating frame 213, as well as between the screen 10 and the second insulating frame 223. Conventional hot melt adhesive or adhesive backing cannot be used to securely bond the screen 10 to the first insulating frame 213 and the second insulating frame 223 for insulation.

[0155] Referring back to Figure 7a, a sealing foam 60 is disposed between the first cover portion 2131 and the first non-display area 151. Specifically, the sealing foam 60 can be fixed to the first cover portion 2131 and abut against the first non-display area 151. Alternatively, the sealing foam 60 can be fixed to the first non-display area 151 and abut against the first cover portion 2131. This facilitates relative movement between the screen 10 and the first insulating frame 213, while also providing a certain degree of waterproofing.

[0156] Static electricity has the characteristics of long-term accumulation, high voltage, low power, small current and short action time. Electrostatic discharge may cause the electronic device 100 to frequently freeze, automatically shut down, have poor picture quality and volume, and have intermittent signal. Therefore, resisting electrostatic discharge (ESD) has become an important part of electronic product quality control. Therefore, electrostatic protection of the electronic device 100 is crucial.

[0157] As previously mentioned, a sealing foam 60 is arranged between the first cover portion 2131 and the first non-display area 151. Those skilled in the art will appreciate that the sealing foam 60 is a porous, loose structure with poor static resistance. When a user uses the electronic device 100 (for example, in winter or by rubbing the side of the screen 10), static electricity can easily accumulate on the surface of the screen 10. Static electricity on the surface of the screen 10 may enter the interior of the electronic device 100 through the pores of the sealing foam 60 and hit the screen cable 90, causing the screen 10 to malfunction and reducing its service life. In particular, when static electricity accumulates in the first section 1511, since the screen cable 90 is closer to the first section 1511, the static electricity can pass through the pores of the sealing foam 60 and hit the screen cable 90, increasing the risk of causing the screen 10 to malfunction.

[0158] In order to solve this technical problem, please refer to Figures 12 and 13. Figure 12 is a three-dimensional view of the first insulating frame 213 shown in Figure 4. Figure 13 is a schematic diagram of the vertical projection of the electrostatic discharge structure 2133 on the first insulating frame 213 shown in Figure 12 on the first middle frame 211. The electronic device 100 includes an electrostatic discharge structure 2133. The electrostatic discharge structure 2133 is stacked and fixed on the surface of the first cover body 2131 facing the first area segment 1511. Specifically, the electrostatic discharge structure 2133 extends to both ends of the first cover body 2131 along the extension direction of the first frame segment D1. The electrostatic discharge structure 2133 is electrically connected to the reference ground. In this way, the static electricity on the surface of the screen 10 can be discharged to the reference ground through the electrostatic discharge structure 2133 without hitting the screen cable of the screen 10, which is beneficial to improving the service life of the screen 10.

[0159] In other examples, the electrostatic discharge structure 2133 may also be stacked and fixed on the first section 1511 , as long as the electrostatic discharge structure 2133 is located on the side facing the first section 1511 .

[0160] While the above technical solution provides excellent electrostatic protection, the electrostatic discharge structure 2133 is arranged in parallel with the first frame segment D1 and extends along the extension direction of the first frame segment D1 to both ends of the first cover portion 2131. This makes the structure relatively long, significantly longer than the length of the antenna radiator D11. Consequently, a portion of the electromagnetic waves radiated by the antenna radiator D11 will reach the electrostatic discharge structure 2133. Furthermore, due to the length of the electrostatic discharge structure 2133, a relatively large amount of electromagnetic waves will reach the structure, easily generating a reverse current in the structure. The direction of this reverse current is opposite to the direction of the current flowing through the antenna radiator D11. This, in turn, causes the electrostatic discharge structure 2133 to reflect the electromagnetic waves. The electromagnetic waves reflected by the electrostatic discharge structure 2133 return to the feed point D111 of the antenna radiator D11, where they cancel out the signal radiated by the antenna radiator D11, significantly reducing the radiation efficiency of the antenna radiator D11.

[0161] Here, it should be understood that the radiation efficiency of antenna 80 refers to the ratio of the power radiated into space by antenna 80 (i.e., the power effectively converted into electromagnetic waves) to the active power input to antenna 80. Active power input to antenna 80 = input power to antenna 80 - antenna 80 loss; antenna 80 loss primarily includes metal ohmic loss and / or dielectric loss.

[0162] To solve the above problems, please refer to Figures 14 and 15. Figure 14 is a schematic diagram of the first insulating frame 213 in the electronic device 100 provided in other embodiments of the present application. Figure 15 is a schematic diagram of the vertical projection of the electrostatic discharge structure 2133 on the first insulating frame 213 shown in Figure 14 on the first middle frame 211. The difference between this embodiment and the embodiment described above is that the electrostatic discharge structure 2133 is defined by a plurality of conductive portions 21331. The plurality of conductive portions 21331 are spaced apart along the extension direction of the first region segment 1511 (for example, the Y-axis direction).

[0163] Here, it is worth emphasizing that the “interval” in the arrangement of the plurality of conductive portions 21331 spaced apart along the extension direction of the first region segment 1511 means that the end faces of any two adjacent conductive portions 21331 face each other and have a certain distance therebetween.

[0164] In the electronic device 100 of the embodiment of the present application, static electricity on the surface of the screen 10 can be discharged to a reference ground via the static discharge structure 2133 without hitting the display cable of the screen 10, thereby improving the service life of the screen 10. Furthermore, although some electromagnetic waves radiated from the antenna radiator D11 may reach the static discharge structure 2133, since the static discharge structure 2133 is defined by a plurality of spaced-apart conductive portions 21331, the originally long static discharge structure 2133 is broken up into a plurality of relatively short conductive portions 213311, making it difficult for reverse current to form on the shorter conductive portions 21331. This can, at least to a certain extent, reduce or avoid reflection of electromagnetic waves from the shorter conductive portions 21331, facilitating electromagnetic waves to radiate outwards by bypassing the shorter conductive portions 21331, thereby improving the radiation efficiency of the antenna 80.

[0165] On this basis, in the direction parallel to the first display surface and aligned with the first area segment 1511 and the first frame segment D1 (e.g., the X-axis direction in FIG. 15 ), there can be one or more conductive portions 21331 opposing the antenna radiator D11. On this basis, in the direction parallel to the first display surface and aligned with the first area segment 1511 and the first frame segment D1, at least one conductive portion 21331 opposing the antenna radiator D11 has a length less than twice the length of the corresponding antenna radiator D11.

[0166] Here, the following explanation is required for the “conductive portion 21331 ” which is parallel to the first display surface and opposite to the antenna radiator D11 in the arrangement direction of the first region segment 1511 and the first frame segment D1 .

[0167] Please refer to Figure 16, which shows the vertical projections of the antenna radiator D11 and the conductive portion 21331 shown in Figure 15 within a plane F parallel to the first display surface. Within plane F parallel to the first display surface, the vertical projection of the antenna radiator D11 is a first projection K1, and the vertical projection of the conductive portion 21331 is a second projection K2. Among the multiple second projections K2, the second projection K2 directly opposite the first projection K1 is a target projection. In other words, among the multiple second projections K2, the target projection is the one whose vertical projection along the X-axis onto the first projection K1 overlaps with the first projection K1. This target projection is the vertical projection of the conductive portion 21331 on plane F, parallel to the first display surface and aligned with the first area segment 1511 and the first frame segment D1, opposite the antenna radiator D11. "Overlap" includes the following two scenarios: Scenario 1: Part of the target projection falls within the first projection K1; Scenario 2: The target projection is completely within the first projection K1.

[0168] Furthermore, it is understood that when there are multiple antenna radiators D11, the same conductive portion 21331 can be opposite to two adjacent antenna radiators D11 in the direction parallel to the first display surface and aligned with the first area segment 1511 and the first frame segment D1. Alternatively, the conductive portion 21331 can be opposite to one antenna radiator D11 in the direction parallel to the first display surface and aligned with the first area segment 1511 and the first frame segment D1, while not being opposite to any of the other antenna radiators D11 in the direction parallel to the first display surface and aligned with the first area segment 1511 and the first frame segment D1.

[0169] It is worth noting that, in the conductive portions 21331 parallel to the first display surface and in the arrangement direction of the first region 1511 and the first frame segment D1, opposite to the antenna radiator D11, the length of at least one conductive portion 21331 is less than twice the length of the corresponding antenna radiator D11, including the following situations:

[0170] Case 1: In the direction parallel to the first display surface and in the arrangement direction of the first area segment 1511 and the first frame segment D1, there is only one conductive portion 21331 opposite to the antenna radiator D11, and the length of the conductive portion 21331 is less than twice the length of the antenna radiator D11.

[0171] Scenario 2: In a direction parallel to the first display surface and in the arrangement direction of the first area segment 1511 and the first frame segment D1, there are multiple conductive portions 21331 opposite to the antenna radiator D11, and the lengths of some of the multiple conductive portions 21331 are less than twice the length of the antenna radiator D11, while the lengths of other conductive portions 21331 are equal to or greater than twice the length of the antenna radiator D11.

[0172] Case 3: In a direction parallel to the first display surface and in the arrangement direction of the first region 1511 and the first frame segment D1 , the length of the conductive portion 21331 opposite to the antenna radiator D11 is less than twice the length of the antenna radiator D11 .

[0173] Since the length of at least one of the conductive parts 21331 that are parallel to the first display surface and opposite to the arrangement direction of the first area segment 1511 and the first frame segment D1 of the antenna radiator D11 is less than twice the length of the antenna radiator D11, it is beneficial to further reduce the length of the conductive part 21331, and thus can further reduce or avoid the reflection of electromagnetic waves caused by the conductive part 21331 with a smaller length, which is beneficial for the electromagnetic waves to bypass the conductive part 21331 with a smaller length and radiate to the outside world, and then it is beneficial to improve the radiation efficiency of the antenna 80 at least to a certain extent.

[0174] On this basis, in some embodiments, in the conductive portion 21331 parallel to the first display surface and opposite to the antenna radiator D11 in the arrangement direction of the first area segment 1511 and the first frame segment D1, the length of at least one conductive portion 21331 is smaller than the length of the corresponding antenna radiator D11, thereby facilitating further reducing the length of the conductive portion 21331, and further reducing or avoiding the reflection of electromagnetic waves caused by the conductive portion 21331 with a smaller length, which is conducive to the electromagnetic waves bypassing the conductive portion 21331 with a smaller length to radiate to the outside world, and then helping to improve the radiation efficiency of the antenna 80 at least to a certain extent.

[0175] In some specific examples, please continue to refer to Figures 15-16. In order to further improve the radiation efficiency of the antenna 80, in the direction parallel to the first display surface and in the arrangement direction of the first area segment 1511 and the first frame segment D1, the length of the conductive part 21331 opposite to the antenna radiator D11 is less than the length of the antenna radiator D11.

[0176] For example, the material of the electrostatic discharge structure 2133 can be silver, copper, graphite or conductive cloth, so as to improve the electrostatic conduction effect.

[0177] Exemplarily, the electrostatic discharge structure 2133 can be a coating or plating layer adhered to the surface of the first cover portion 2131. For example, a conductive silver paste is printed on the first cover portion 2131 to form a whole layer of electrostatic discharge structure layer without disconnection, and then the electrostatic discharge structure layer is cut by a laser engraving process or other processes to obtain an electrostatic discharge structure 2133 including a plurality of spaced conductive portions 21331. For another example, copper is electroplated on the surface of the first cover portion 2131 by an electroplating process to form a whole layer of electrostatic discharge structure layer without disconnection, and then the electrostatic discharge structure layer is cut by a laser engraving process or other processes to obtain a plurality of spaced conductive portions 21331. For another example, the electrostatic discharge structure 2133 can also be made of a sheet. The sheet is fixed to the first cover portion 2131 by gluing.

[0178] On this basis, in some specific examples, please refer to Figures 15 and 16. To further improve the radiation efficiency of the antenna 80 and simplify the processing of the electrostatic discharge structure 2133, the number of conductive portions 21331 opposing the antenna radiator D11 in the direction parallel to the first display surface and in the arrangement of the first area segment 1511 and the first frame segment D1 ranges from 2 to 5. For example, the number of conductive portions 21331 opposing the antenna radiator D11 in the direction parallel to the first display surface and in the arrangement of the first area segment 1511 and the first frame segment D1 is 2, 3, or 4.

[0179] This helps shorten the length of the conductive portion 21331, which is parallel to the first display surface and opposite the antenna radiator D11 in the arrangement direction of the first region 1511 and the first frame segment D1. This helps to largely prevent the formation of reverse current on the conductive portion 21331, thereby largely reducing or avoiding the reflection of electromagnetic waves by the conductive portion 21331. This helps to largely allow electromagnetic waves to bypass the conductive portion 21331 and radiate to the outside world, thereby further improving the radiation efficiency of the antenna 80. Furthermore, compared with providing more conductive portions 21331, this helps simplify the processing of the electrostatic discharge structure 21333, improving processing efficiency and reducing processing costs.

[0180] Based on the above embodiment, to achieve electrical connection between the electrostatic discharge structure 2133 and the reference ground, please refer to Figures 14 and 15. At least one of the multiple conductive portions 21331 is a first conductive portion 2133a. An electrostatic conductor 21321 is provided on the first side portion 2132. A portion of the electrostatic conductor 21321 is located on the surface of the outer peripheral side J1 of the first side portion 2132 facing the first screen portion 11. The remaining portion of the electrostatic conductor 21321 is located on the end surface of the first side portion 2132 facing away from the first display surface. Each first conductive portion 2133a corresponds to one electrostatic conductor 21321. The first conductive portion 2133a is fixed to and electrically connected to the electrostatic conductor 21321. The provision of the electrostatic conductor 21321 facilitates the discharge of static electricity from the first conductive portion 2133a to the reference ground via the electrostatic conductor 21321.

[0181] It can be understood that in other examples, the electrostatic conductor 21321 can also be located entirely on the surface of the outer peripheral side J1 of the first side portion 2132 facing the first screen portion 11, as long as at least a portion of the electrostatic conductor 21321 is located on the surface of the outer peripheral side J1 of the first side portion 2132 facing the first screen portion 11.

[0182] It should be emphasized here that the first conductive portion 2133 a refers to a conductive portion 21331 among the plurality of conductive portions 21331 that is fixed and connected to the electrostatic conductor 21321 .

[0183] Continuing with Figures 14 and 15 , there can be multiple first conductive portions 2133a. When there are multiple first conductive portions 2133a, there can also be multiple electrostatic conductors 21321, with the multiple electrostatic conductors 21321 corresponding one-to-one with the multiple first conductive portions 2133a. Of course, in other examples, there can also be a single first conductive portion 2133a, in which case there can also be a single electrostatic conductor 21321.

[0184] On this basis, in order to facilitate the fixed connection between the first conductive portion 2133a and the electrostatic conductor 21321, please continue to refer to Figures 14 and 15. The first conductive portion 2133a includes a first sub-conductive portion 2133a1 and a second sub-conductive portion 2133a2.

[0185] The first sub-conductive portion 2133a1 extends along the extension direction of the first region 1511, that is, the spacing direction of the plurality of conductive portions 21331. The first sub-conductive portion 2133a1 is spaced apart from the corresponding electrostatic conductor 21321. The extension path of the first sub-conductive portion 2133a1 includes, but is not limited to, a straight line, a curve, or a broken line.

[0186] The second sub-conductive portion 2133a2 is located between the electrostatic conductor 21321 and the first sub-conductive portion 2133a1. Furthermore, the second sub-conductive portion 2133a2 is fixed and electrically connected between the electrostatic conductor 21321 and the first sub-conductive portion 2133a1. This creates a shorter static discharge path between the electrostatic conductor 21321 and the first sub-conductive portion 2133a1.

[0187] For example, the second sub-conductive portion 2133a2 and the first sub-conductive portion 2133a1 are formed as an integral piece, which is helpful in simplifying the processing technology between the two and reducing the manufacturing cost.

[0188] In some embodiments, to reduce the impact of the electrostatic conductor 21321 on the radiation efficiency of the antenna 80, the size of the electrostatic conductor 21321 in the direction of spacing between the multiple conductive portions 21331 (i.e., the extension direction of the first region 1511, such as the Y-axis direction in FIG. 15 ) is smaller than or equal to the size of the second sub-conductive portion 2133a2 in the direction of spacing between the multiple conductive portions 21331. Of course, it is understood that in other examples, the size of the electrostatic conductor 21321 in the direction of spacing between the multiple conductive portions 21331 may also be larger than the size of the second sub-conductive portion 2133a2 in the direction of spacing between the multiple conductive portions 21331.

[0189] In some embodiments, in order to further reduce the impact of the conductive portion 21331 on the radiation efficiency of the antenna 80, the size of the second sub-conductive portion 2133a2 in the spacing direction of multiple conductive portions 21331 is smaller than the size of the first sub-conductive portion 2133a1 in the spacing direction of multiple conductive portions 21331.

[0190] Illustratively, the ratio of the dimension of the second sub-conductive portion 2133a2 in the direction of spacing between the plurality of conductive portions 21331 to the dimension of the first sub-conductive portion 2133a1 in the direction of spacing between the plurality of conductive portions 21331 is greater than 0 and less than or equal to 0.5. For example, the ratio of the dimension of the second sub-conductive portion 2133a2 in the direction of spacing between the plurality of conductive portions 21331 to the dimension of the first sub-conductive portion 2133a1 in the direction of spacing between the plurality of conductive portions 21331 is 0.1, 0.15, 0.18, 0.2, 0.22, 0.25, 0.28, 0.3, 0.32, 0.35, 0.38, or 0.4.

[0191] Of course, it is understandable that, in other examples, the size of the second sub-conductive portion 2133a2 in the spacing direction of the multiple conductive parts 21331 may also be equal to the size of the first sub-conductive portion 2133a1 in the spacing direction of the multiple conductive parts 21331.

[0192] On this basis, because the first side portion 2132 cooperates with the positioning step F2, the electrostatic conductor 21321 and the positioning step F2 are opposite each other in the Z-axis direction. Furthermore, because the antenna radiator D11 is grounded and electrically connected to the circuit board 30, which includes a grounded metal layer, the electrostatic conductor 21321 and the connection portion F3 of the antenna radiator D11 are aligned and electrically connected in the Z-axis direction. This allows the connection portion F3 to be used as part of the electrostatic discharge path, facilitating the discharge of static electricity to the reference ground through the connection portion F3, thereby shortening the electrostatic discharge path.

[0193] It should be noted that the "electrical connection" between the electrostatic conductor 21321 and the connection portion F3 can be a coupled feed electrical connection. Alternatively, conductive adhesive can be provided between the connection portion F3 and the electrostatic conductor 21321 to achieve a physical electrical connection between the two. It should also be noted that coupled feed refers to the conduction of electrical energy between two circuit elements or circuit networks that are not in contact but are located at a certain distance, such as in fields such as communications.

[0194] Based on the aforementioned embodiment in which the electrostatic conductor 21321 and the connection portion F3 are aligned in the Z-axis direction, since the first middle plate 2111 and the screen 10 are stacked in the Z-axis direction, based on this positional relationship, to further shorten the electrostatic discharge path, refer to FIG. 17 , and in conjunction with FIG. 15 , FIG. 17 is a schematic diagram illustrating the positional relationship between a portion of the first frame segment D1 and the circuit board 30 shown in FIG. The electrostatic conductor 21321 includes a first-type electrostatic conductor N. The first conductive portion 2133a, fixed to and electrically connected to the first-type electrostatic conductor N, is the first-type conductive portion. In FIG. 17 , the vertical projection of the first-type electrostatic conductor N on the connection portion F3 is region N'. The first-type electrostatic conductor N is aligned in the Z-axis direction with the grounding point D112. This allows static electricity on the first-type conductive portion to be discharged to the reference ground sequentially through the first-type electrostatic conductor N, the grounding point D112, and the grounding connector 82, shortening the overall electrostatic discharge path.

[0195] Due to the structural layout of the electronic device 100, not every conductive part 21331 can be independently designed with an electrostatic discharge path. Based on this, in order to achieve that each conductive part 21331 of the electrostatic discharge structure 2133 can be electrically connected to the reference ground to improve the reliability of electrostatic discharge and simplify the electrostatic discharge path of each conductive part 21331, please refer back to Figures 14 and 15. Among the multiple conductive parts 21331, in addition to the first conductive part 2133a, at least one of the other conductive parts 21331 is a second conductive part 2133b. Exemplarily, among the multiple conductive parts 21331, in addition to the first conductive part 2133a, each of the remaining conductive parts 21331 is a second conductive part 2133b. Of course, it is understandable that the conductive part 21331 may also not include the second conductive part 2133b.

[0196] The second conductive portion 2133b is spaced apart from the electrostatic conductor 21321 on the first insulating frame 213 and has no direct physical connection therebetween. The second conductive portion 2133b discharges static electricity to the first conductive portion 2133a closest to the second conductive portion 2133b.

[0197] Specifically, the second conductive portion 2133b and the first conductive portion 2133a closest to the second conductive portion 2133b can be electrically connected in a manner that allows for static electricity conduction without degrading the radiation efficiency of the antenna 80 or having a negligible effect on the radiation frequency of the antenna 80. This facilitates the conduction of static electricity through the second conductive portion 2133b to the first conductive portion 2133a closest to the second conductive portion 2133b, thereby facilitating the design of the positions of the first conductive portion 2133a and the second conductive portion 2133b based on the structural layout of the electronic device 100 and optimizing the static electricity discharge path of the static electricity discharge structure 2133.

[0198] For example, there may be one or more second conductive portions 2133b. The extension path of the second conductive portion 2133b includes, but is not limited to, a straight line, a curve, or a broken line.

[0199] On this basis, to facilitate the discharge of static electricity from the second conductive portion 2133b to the first conductive portion 2133a, please continue to refer to Figures 14 and 15. In the direction of spacing between the plurality of conductive portions 21331, a first conductive portion 2133a adjacent to the second conductive portion 2133b is arranged on at least one side of each second conductive portion 2133b. In other words, in the direction of spacing between the plurality of conductive portions 21331, a first conductive portion 2133a adjacent to the second conductive portion 2133b may be arranged on one side of each second conductive portion 2133b in the Y-axis direction, or a first conductive portion 2133a adjacent to the second conductive portion 2133b may be arranged on both sides of each second conductive portion 2133b in the direction of spacing between the plurality of conductive portions 21331.

[0200] It should be noted that the "adjacent" in the phrase "a first conductive portion 2133a adjacent to the second conductive portion 2133b is arranged on at least one side of each second conductive portion 2133b in the spacing direction of the plurality of conductive portions 21331" refers to the conductive portions 21331. The second conductive portion 2133b being adjacent to the first conductive portion 2133a means that there is no conductive portion 21331 between the second conductive portion 2133b and the first conductive portion 2133a.

[0201] For example, please continue to refer to Figures 14 and 15. There are multiple second conductive parts 2133b and multiple first conductive parts 2133a. In the spacing direction of the multiple conductive parts 21331, the multiple second conductive parts 2133b and the multiple first conductive parts 2133a are arranged alternately. Of course, the present application is not limited to this. In other examples, please refer to Figure 18, which is a schematic diagram of the vertical projection of the electrostatic discharge structure 2133 in the electronic device 100 provided in some embodiments of the present application on the first middle frame 211. In this embodiment, two second conductive parts 2133b are arranged between the two first conductive parts 2133a that are closest to each other.

[0202] Based on the aforementioned embodiment where "a first conductive portion 2133a adjacent to the second conductive portion 2133b is disposed on at least one side of each second conductive portion 2133b in the direction of spacing between the plurality of conductive portions 21331," and referring to Figures 14-15 and 18, an air gap H is formed between the second conductive portion 2133b and the first conductive portion 2133a adjacent to the second conductive portion 2133b. This air gap H is configured to couple and electrically connect the two conductive portions 21331. This design ensures the conduction of static electricity without affecting the radiation efficiency of the antenna 80. Furthermore, it has a simple structure and is easy to manufacture.

[0203] On this basis, to improve the reliability of the coupling and feeding between the second conductive portion 2133b and the first conductive portion 2133a adjacent to the second conductive portion 2133b, the size of the air gap H is less than 0.5 mm. For example, the size of the air gap H is less than 0.05 mm. Exemplarily, the size of the air gap H is 0.035 mm, 0.038 mm, 0.04 mm, 0.042 mm, 0.045 mm, or 0.048 mm.

[0204] Please refer to Figure 19, which is a schematic diagram of a vertical projection of the electrostatic discharge structure 2133 in the electronic device 100 provided in some other embodiments of the present application on the first middle frame 211. The difference between this embodiment and the embodiment shown in Figure 15 is that: in this embodiment, the second conductive part 2133b and the first conductive part 2133a adjacent to the second conductive part 2133b are no longer electrically connected by coupling feeding. The second conductive part 2133b and the first conductive part 2133a adjacent to the second conductive part 2133b are electrically connected through the inductance structure G1. Specifically, the inductance structure G1 can be fixed on the surface of the first cover body 2131, or it can be fixed to the first area segment 1511. The inductance of the inductance structure G1 ranges from 1nH to 100nH.

[0205] Specifically, since the operating frequency of antenna 80 is often in the gigahertz range, which is high frequency, while the frequency of static electricity is generally tens of megahertz, which is low frequency, the two frequencies are of completely different orders of magnitude. As a result, the inductor structure G1, with an inductance range of 1nH to 100nH, is close to a short circuit for static electricity, but close to an open circuit for antenna 80. In this way, when static electricity accumulates on the second conductive portion 2133b, it can be transferred through the second conductive portion 2133b to the first conductive portion 2133a, which is closest to the second conductive portion 2133b. This ensures the conduction of static electricity without affecting the radiation efficiency of antenna 80.

[0206] Exemplarily, the inductance of the inductor structure G1 is 10 nH (nanohenry), 20 nH, 30 nH, 40 nH, 50 nH, 60 nH, 70 nH, 80 nH, or 90 nH.

[0207] On this basis, in some embodiments, in order to further improve the reliability of the inductor structure G1 for electrostatic conduction while ensuring the radiation efficiency of the antenna 80, when the operating frequency of the antenna 80 is 1.5GHz~6GHz, the inductance of the inductor structure G1 is 1~20nH.

[0208] Exemplarily, the inductor structure G1 can be a metal serpentine wire fixed to the first cover portion 2131. In this way, it is beneficial to reduce the size of the inductor structure G1 in the Z-axis direction, which is beneficial to reducing the thickness of the electronic device 100, and realizing the compactness of the structure of the electronic device 100. Moreover, the structure is simple, easy to process and manufacture, and low in cost. Exemplarily, the material of the metal serpentine wire and the electrostatic discharge structure 2133 can be the same. In this way, selecting a material to process the metal serpentine wire and the electrostatic discharge structure 2133 is beneficial to improving the reliability of the electrical connection between the two. Of course, it is understandable that in other examples, the material of the metal serpentine wire and the electrostatic discharge structure 2133 can also be different.

[0209] On this basis, in some embodiments, the metal serpentine wire and the conductive portion 21331 connected to the metal serpentine wire can be formed as an integral part. This simplifies the processing between the electrostatic discharge structure 2133 and the metal serpentine wire, improves processing efficiency, and also enhances the reliability of the connection between the metal serpentine wire and the electrostatic discharge structure 2133.

[0210] Please refer to Figure 20, which is a schematic diagram of a vertical projection of the electrostatic discharge structure 2133 on the first middle frame 211 in the electronic device 100 provided in other embodiments of the present application. The difference between this embodiment and the embodiment shown in Figure 19 is that the second conductive portion 2133b and the first conductive portion 2133a adjacent to the second conductive portion 2133b are no longer electrically connected via the inductor structure G1. The second conductive portion 2133b and the first conductive portion 2133a adjacent to the second conductive portion 2133b are electrically connected via the electrostatic protection device G2.

[0211] In some embodiments, the ESD protection device G2 has a breakdown voltage. When the voltage discharged to the ESD protection device exceeds the breakdown voltage, the ESD protection device G2 is turned on. Since the voltage of static electricity is often high, while the voltage of the antenna 80 is often low, when the voltage of the static electricity at the second conductive portion 2133b is greater than the breakdown voltage, the ESD protection device G2 will electrically connect the second conductive portion 2133b and the first conductive portion 2133a adjacent to the second conductive portion 2133b, thereby discharging the static electricity to the first conductive portion 2133a.

[0212] Exemplarily, the electrostatic protection device G2 can be a transient voltage suppressor (TVS). TVS is a high-performance protection device. When the second conductive portion 2133b does not accumulate static electricity, the TVS is in a cut-off state (high resistance state); when the second conductive portion 2133b accumulates static electricity, and the voltage of the static electricity reaches the breakdown voltage and is discharged to the TVS, the TVS becomes a low-resistance state, providing a low-impedance conduction path for the transient current, while discharging the static electricity to the first conductive portion 2133a.

[0213] As another example, the electrostatic protection device G2 can also be a varistor, for example, a thin film varistor. A varistor is a nonlinear resistance element, which refers to a voltage-limiting element that reacts sensitively to voltage changes. The resistance of a varistor is related to the magnitude of the voltage applied at both ends. When the second conductive part 2133b does not accumulate static electricity, the voltage applied to the varistor is within the breakdown voltage, the resistance of the resistor is infinite, and almost no current passes through. When static electricity accumulates on the surface of the second conductive part 2133b, and the static electricity is discharged to the varistor, and the voltage across the varistor is greater than the breakdown voltage, the varistor quickly breaks down and turns on, and its resistance drops rapidly, causing the varistor to be in a conductive state, while discharging the static electricity to the first conductive part 2133a.

[0214] Due to the placement of the ground point D112 on the antenna radiator D11, not all first-type electrostatic conductors N can directly face the ground point D112 in the Z-axis direction. To ensure that each first conductive portion 2133a has an electrostatic discharge path with the reference ground, thereby improving the electrostatic discharge effect, please refer to Figures 21 and 22. Figure 21 is a schematic diagram illustrating the positional relationship between a portion of the first frame segment D1 and the circuit board 30 in the electronic device 100 provided in other embodiments of the present application. Figure 22 is a schematic diagram illustrating the vertical projection of the electrostatic discharge structure 2133 in the electronic device 100 shown in Figure 21 onto the first middle frame 211. The electrostatic conductors 21321 also include a second-type electrostatic conductor M. The first conductive portion 2133a corresponding to the second-type electrostatic conductor M is the second-type conductive portion. In Figures 21 and 22, the vertical projection of the second-type electrostatic conductor M on the connection portion F3 is indicated by the region M'. The second-type electrostatic conductor M directly faces the feed point D111 in the thickness direction of the first screen portion 11.

[0215] Please refer to Figure 23, which is a schematic diagram of the electrical connections of the electronic device 100 shown in Figure 21. The electronic device 100 also includes an electronic device. The electronic device is fixed to the circuit board. In the specific example shown in Figure 23, the electronic device is an inductor V1. Inductor V1 and the RF chip 70 are connected in parallel between the feed structure 81 and the ground metal layer. The inductance of inductor V1 ranges from 1nH to 100nH.

[0216] Specifically, since the operating frequency of antenna 80 is often in the gigahertz range, which is high frequency, while the frequency of static electricity is generally tens of megahertz, which is low frequency, inductor V1, with an inductance range of 1nH to 100nH, acts nearly as a short circuit for static electricity and nearly as an open circuit for antenna 80. This allows static electricity to be discharged from the second-class static conductor M to the feed point D111 via inductor V1 to the grounded metal layer. Furthermore, inductor V1 does not degrade the radiation efficiency of antenna 80, thus helping to regulate the resonance of antenna 80, at least to a certain extent.

[0217] Exemplarily, the inductance of the inductor V1 is 10 nH, 20 nH, 30 nH, 40 nH, 50 nH, 60 nH, 70 nH, 80 nH, or 90 nH.

[0218] On this basis, in some embodiments, in order to further improve the reliability of electrostatic conduction of the inductor V1 while ensuring the radiation efficiency of the antenna 80, when the operating frequency of the antenna 80 is 1.5GHz~6GHz, the inductance of the inductor V1 ranges from 1 to 20nH.

[0219] It is worth noting that the first type of electrostatic conductor N and the second type of electrostatic conductor M are divided based on the different positional relationships between the electrostatic conductor 21321 and the feeding point D111 and the grounding point D112 on the antenna radiator D11. Of course, it is understood that the electrostatic conductor 21321 may include only the first type of electrostatic conductor N or only the second type of electrostatic conductor M. Similarly, the first conductive portion 2133a may include only the first type of conductive portion or only the second type of conductive portion.

[0220] Please refer to Figure 24, which is a schematic diagram of the electrical connections of electronic device 100 in some other possible embodiments of the present application. This embodiment differs from the embodiment shown in Figure 23 in that the electronic device is an ESD protection device V2. ESD protection device V2 and RF chip 70 are connected in parallel between the feed structure 81 and the ground metal layer 301.

[0221] Exemplarily, the electrostatic protection device V2 has a breakdown voltage. When the electrostatic voltage discharged to the electrostatic protection device V2 is greater than the breakdown voltage, the electrostatic protection device V2 is turned on. Since the voltage of static electricity is often high, while the voltage of the antenna 80 is often low, when the electrostatic voltage discharged to the feeding point is greater than the breakdown voltage, the electrostatic protection device V2 is electrically turned on and discharges the static electricity to the ground metal layer 301.

[0222] For example, the electrostatic protection device V2 may be a transient voltage suppressor diode or a varistor. The specific protection principles of the transient voltage suppressor diode and the varistor have been described above and will not be described again here.
