Description

Technical Field

[0001] The present application relates to the technical field of electronic products, and in particular to an electronic device. Background Art

[0002] When electronic devices are in use (for example, when using electronic devices in winter or rubbing the screen), static electricity is easily accumulated on the screen surface. Static electricity may be discharged into the electronic device and hit the screen cable. Therefore, static electricity can cause the screen to malfunction and reduce the service life of the screen. Summary of the invention

[0003] The present application provides an electronic device, which is intended to solve the problem of a screen not functioning properly due to static electricity, at least to a certain extent, and is also beneficial for improving the radiation efficiency of an antenna.

[0004] In order to achieve the above objectives, this application adopts the following technical solutions:

[0005] 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 has a first display surface, the first display surface includes a first display area and a first non-display area, the first non-display area is located at the periphery of the first display area and is connected to the first display area, and the first non-display area includes a first area segment; the first frame is located on the side facing the peripheral side of the first screen portion, the first frame includes a first frame segment, the first frame segment is used to form at least one antenna radiator, and the first area segment is between the first frame segment and the first display area; the electrostatic discharge structure is located on the side facing the first area segment, and the electrostatic discharge structure includes a plurality of conductive parts, and the plurality of conductive parts are arranged at intervals in the extension direction of the first area segment.

[0006] In the electronic device of the embodiment of the present application, the static electricity on the screen surface can be discharged to the reference ground through the static discharge structure, and will not hit the screen cable of the screen, which is beneficial to improve the service life of the screen. In addition, although part of the electromagnetic waves radiated by the antenna radiator to the surroundings may reach the static discharge structure, since the static discharge structure is defined by a plurality of spaced conductive parts, it is beneficial to disconnect the originally long static discharge structure to form a plurality of relatively short conductive parts, so that it is difficult to form a reverse current on the conductive part with a smaller length, and then it can at least reduce or avoid the reflection of the electromagnetic wave by the conductive part with a smaller length to a certain extent, which is beneficial for the electromagnetic wave to bypass the conductive part with a smaller length and radiate to the outside world, and then it is beneficial to at least improve the radiation efficiency of the antenna to a certain extent.

[0007] Exemplarily, the plurality of conductive portions define an electrostatic discharge structure.

[0008] For example, the material of the electrostatic discharge structure can be silver, copper, graphite or conductive cloth, so that the electrostatic conduction effect can be improved.

[0009] In a possible implementation of the present application, in the conductive portion parallel to the first display surface and in the arrangement direction of the first region segment and the first frame segment, the length of at least one conductive portion opposite to the antenna radiator is less than twice the length of the corresponding antenna radiator. Thus, the reflection of electromagnetic waves by the conductive portion with a smaller length can be further reduced or avoided, which is conducive to the electromagnetic waves bypassing the conductive portion with a smaller length to radiate to the outside world, thereby further improving the radiation efficiency of the antenna.

[0010] In a possible implementation of the present application, in the conductive portion parallel to the first display surface and in the arrangement direction of the first region segment and the first frame segment, the length of at least one conductive portion opposite to the antenna radiator is smaller than the length of the corresponding antenna radiator. Thus, the reflection of electromagnetic waves by the conductive portion with a smaller length can be further reduced or avoided, which is conducive to the electromagnetic waves bypassing the conductive portion with a smaller length to radiate to the outside world, thereby further improving the radiation efficiency of the antenna.

[0011] In a possible implementation of the present application, in a direction parallel to the first display surface and in the arrangement direction of the first region segment and the first frame segment, the length of the conductive portion opposite to the antenna radiator is shorter than the length of the corresponding antenna radiator. Thus, the reflection of electromagnetic waves by the conductive portion with a shorter length can be further reduced or avoided, which is conducive to the electromagnetic waves bypassing the conductive portion with a shorter length to radiate to the outside world, thereby further improving the radiation efficiency of the antenna.

[0012] In a possible implementation of the present application, in a direction parallel to the first display surface and in the arrangement direction of the first region segment and the first frame segment, the number of conductive portions opposite to the antenna radiator ranges from 2 to 5. Thus, the radiation efficiency of the antenna can be further improved, while simplifying the processing technology of the electrostatic discharge structure.

[0013] In a possible implementation of the present application, the first frame has a first end face, and the first end face is in the same direction as the first display surface; the electronic device also includes a first insulating frame, which is located on the side facing the first end face and is fixedly connected to the first frame, and the first insulating frame includes a first cover portion, which is stacked and arranged on the side facing the first non-display area, and the electrostatic discharge structure is stacked and fixed on the surface of the first cover portion facing the first area segment. In this way, on the one hand, the first insulating frame can be used to cover the gap between the first screen portion and the first frame, thereby optimizing the appearance of the electronic device.

[0014] Exemplarily, the electrostatic discharge structure can be a coating or plating layer attached to the surface of the first cover body, so that the thickness dimension occupied by the electrostatic discharge structure is relatively small.

[0015] In a possible implementation of the present application, the first insulating frame further includes a first side portion, the first side portion is located on the side to which the outer peripheral side surface of the first screen portion faces, one end of the first side portion is connected to the first cover portion, 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. This is conducive to improving the assembly efficiency between the first insulating frame and the first frame.

[0016] In a 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 part 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 and electrically connected to the electrostatic conductor. In this way, the provision of the electrostatic conductor is conducive to the first conductive part to discharge static electricity to the reference ground through the electrostatic conductor.

[0017] 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 rest 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 a part of the electrostatic discharge path, which is beneficial to use the connecting portion to discharge static electricity to the reference ground, thereby achieving the purpose of shortening the electrostatic discharge path.

[0018] In a possible implementation of the present application, the electrostatic conductor includes a first type of electrostatic conductor, the connection portion has a grounding point, and the grounding point is directly opposite to the first type of electrostatic conductor in the thickness direction of the first screen portion; the electronic device includes a first middle plate, the first frame is fixed to the outer peripheral edge of the first middle plate, the first middle plate includes a conductive part, the conductive part and the grounding point are fixed and electrically connected, and the conductive part is used as a reference ground. In this way, the static electricity on the first type of conductive part fixed and electrically connected to the first type of electrostatic conductor can be discharged to the reference ground through the first type of electrostatic conductor and the grounding point in sequence, and the entire static electricity discharge path is relatively short.

[0019] In a possible implementation of the present application, the first middle plate also includes an insulating portion, which is fixed and directly connected between the conductive portion and the connecting portion; the electronic device also includes a grounding connector, which is provided on the insulating portion and is fixed and electrically connected between the conductive portion and the grounding point, and the size of the grounding connector in the extension direction of the first area segment is smaller than the size of the corresponding antenna radiator in the extension direction of the first area segment. In this way, on the one hand, the insulating portion can be used to separate the antenna radiator from the conductive portion to meet the clearance requirements of the antenna radiator; on the other hand, the grounding connector can also be used to achieve grounding of the antenna radiator; on the other hand, the size of the grounding connector in the extension direction of the first area segment is smaller than the size of the corresponding antenna radiator in the extension direction of the first area segment, which is conducive to ensuring the radiation efficiency of the antenna.

[0020] In a possible implementation of the present application, the insulating portion wraps the grounding connector, which is beneficial for isolating the grounding connector from other structures by using the insulating portion, thereby improving the electrical connection reliability of the electronic device.

[0021] 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 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.

[0022] In a possible implementation of the present application, the electrostatic protection device is a varistor or a transient voltage suppression diode.

[0023] In a possible implementation of the present application, the first conductive part includes a first sub-conductive part and a second sub-conductive part, the first sub-conductive part extends in the extension direction of the first region, the first sub-conductive part is spaced apart from the corresponding electrostatic conductor, and the second sub-conductive part is fixed and electrically connected between the corresponding electrostatic conductor and the first sub-conductive part. In this way, the electrical connection between the first conductive part and the electrostatic conductor can be facilitated, and a shorter electrostatic discharge path can be provided between the first sub-conductive part and the electrostatic conductor.

[0024] Exemplarily, the second sub-conductive portion and the first sub-conductive portion are formed as an integral part, which is helpful to simplify the processing technology between the two and reduce the manufacturing cost.

[0025] In a 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 influence of the electrostatic conductor on the radiation efficiency of the antenna.

[0026] In a possible implementation of the present application, the size of the second sub-conductive part in the extension direction of the first region segment is smaller than the size of the first sub-conductive part in the extension direction of the first region segment, thereby reducing the influence of the second sub-conductive part on the radiation efficiency of the antenna.

[0027] Exemplarily, the ratio of the size of the second sub-conductive portion in the extension direction of the first region segment to the size of the first sub-conductive portion in the extension direction of the first region 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 extension direction of the first region segment to the size of the first sub-conductive portion in the extension direction of the first region 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.

[0028] In a possible implementation of the present application, at least one of the remaining conductive parts other than the first conductive part is a second conductive part, and the second conductive part is separated from the electrostatic conductor. The provision of the second conductive part is conducive to designing the positions of the first conductive part and the second conductive part according to the structural layout of the electronic device, and optimizing the electrostatic discharge path of the electrostatic discharge structure.

[0029] In a possible implementation of the present application, in the extension direction of the first region, at least one side of the second conductive portion is provided with a first conductive portion adjacent to the second conductive portion, so that static electricity at the second conductive portion is facilitated to be discharged to the first conductive portion.

[0030] In a possible implementation of the present application, there are multiple first conductive parts and multiple second conductive parts, and in the extension direction of the first region segment, the first conductive parts and the second conductive parts are arranged alternately.

[0031] In a 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, and the air gap is configured to couple the two conductive portions for feeding and electrical connection. Such a design can ensure the conduction of static electricity without affecting the radiation efficiency of the antenna 80, and has a simple structure and is easy to manufacture.

[0032] In a possible implementation of the present application, the size of the air gap is less than 0.5 mm, which is helpful to ensure the reliability of coupling and feeding between the first conductive part and the second conductive part.

[0033] 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.

[0034] In a possible implementation of the present application, the second conductive part and the first conductive part adjacent to the second conductive part 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, and close to an open circuit for the antenna. When static electricity accumulates at the second conductive part, the static electricity can be discharged through the second conductive part to the first conductive part that is closest to the second conductive part, which can ensure the discharge of static electricity without affecting the radiation efficiency of the antenna.

[0035] Exemplarily, the inductance of the inductor structure is 10nH, 20nH, 30nH, 40nH, 50nH, 60nH, 70nH, 80nH, or 90nH.

[0036] In a possible implementation of the present application, the electronic device includes an antenna, the antenna includes an antenna radiator, the working frequency of the antenna is 1.5 GHz to 6 GHz, and the inductance of the inductor structure is 1 to 20 nH. In this way, the reliability of the inductor structure for electrostatic conduction is improved while ensuring the radiation efficiency of the antenna.

[0037] In a possible implementation of the present application, the inductor structure is an inductor, which has a simple structure and low cost.

[0038] In a possible implementation of the present application, the inductor structure is a metal serpentine line, which is helpful to reduce the thickness of the inductor structure itself, thereby reducing the thickness of the electronic device, achieving the compactness of the electronic device, and having a simple structure, easy processing and manufacturing, and low cost.

[0039] Exemplarily, the material of the metal serpentine wire and the electrostatic discharge structure can be the same. In this way, selecting a material to process the metal serpentine wire and the electrostatic discharge structure is conducive 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 can also be different.

[0040] In a possible implementation of the present application, the inductor structure is a metal serpentine wire fixed to the first cover body, and the metal serpentine wire and the conductive part connected to the metal serpentine wire are an integrally formed part. This is conducive to simplifying the processing technology between the electrostatic discharge structure and the metal serpentine wire, improving the processing efficiency, and also improving the connection reliability between the metal serpentine wire and the electrostatic discharge structure.

[0041] In a possible implementation of the present application, the second conductive part and the first conductive part adjacent to the second conductive part are electrically connected via an electrostatic protection device, so that the static electricity at the second conductive part can be discharged to the first conductive part while ensuring the radiation efficiency of the antenna.

[0042] In a possible implementation of the present application, the electrostatic protection device is a varistor or a transient voltage suppression diode, thereby achieving high reliability of electrostatic discharge.

[0043] In a possible implementation of the present application, the electronic device also includes a screen cable and a sealing foam. One end of the screen cable is connected to the portion of the outer peripheral side of the first screen portion facing the first frame segment, and the sealing foam is fixed to the first cover body 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 body 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 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.

[0044] In a possible implementation of the present application, the screen also includes a second screen portion and a third screen portion, the third screen portion is connected between the first screen portion and the second screen portion; 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 portion, the second shell is used to support and fix the second screen portion, and the rotating mechanism is used to support the third screen portion; 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 an end of the first shell away from the second shell.

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.

[0096] See also Figure 3 , Figure 3 Based on Figure 1The screen 10 and the supporting device 20 are shown in a three-dimensional view of the electronic device 100 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. When the screen 10 displays image information, in order to prevent the display of the screen 10 from leaking light, the non-display area 15 is generally provided with a light shielding layer (such as an ink layer, etc.), thereby preventing the light leakage problem of the display area 14.

[0097] For details, please continue to refer to Figure 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.

[0098] 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 at the periphery of the first display area 141 and is connected to the first display area 141. The peripheral side 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 at the periphery of the second display area 142 and is connected to the second display area 142. The peripheral side 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. And 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.

[0099] The first non-display area 151 and the first display area 141 collectively form a first display surface of the first screen portion 11. The second non-display area 152 and the second display area 142 collectively form a second display surface of the second screen portion 12. The third non-display area 153 and the third display area 143 collectively form a third display surface of the third screen portion 13.

[0100] Please continue reading Figure 3, a section of the first non-display area 151 along its own extension trajectory is the first area segment 1511, that is, the first non-display area 151 includes the first area segment 1511. The first area segment 1511 is located on the side of the first display area 141 away from the second display area 142. Of course, it can be understood that, in other examples, the first area segment 1511 can also 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 area segment 1511 is located on the side of the first display area 141 away from the second display area 142, and the other portion is located on one side of the first display area 141 in the Y-axis direction.

[0101] Please continue reading Figure 2 and Figure 3 The supporting device 20 includes a first shell 21 , a second shell 22 and a rotating mechanism 23 .

[0102] Understandably, Figure 2 and Figure 3 Only some components of the support device 20 are schematically shown, and the actual shape, size, position and configuration of these components are not subject to the present invention. Figure 3 restrictions.

[0103] The first housing 21 is used to fix and support the first screen portion 11. Specifically, the first housing 21 has a first support surface M1. The fixing surface of the first screen portion 11 faces the first support surface M1. The first screen portion 11 is stacked and fixed on the first support surface M1. Exemplarily, the connection relationship between the first support surface M1 and the first screen portion 11 includes but is not limited to gluing.

[0104] The second housing 22 is used to fix and support the second screen portion 12. Specifically, the second housing 22 has a second support surface M2. The fixing surface of the second screen portion 12 faces the second support surface M2. The second screen portion 12 is stacked and fixed on the second support surface M2. Exemplarily, the connection relationship between the second support surface M2 and the second screen portion 12 includes but is not limited to gluing.

[0105] 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.

[0106] 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 relative folding or relative unfolding of the first shell 21 and the second shell 22, and further realizing folding or unfolding of the screen 10.

[0107] For more details, please refer to Figure 2In the folded state, the first shell 21 and the second shell 22 are stacked and spaced apart, and the first support surface M1 of the first shell 21 and the second support surface M2 of the second shell 22 are opposite to each other, so that the screen 10 is hidden between the first shell 21 and the second shell 22, thereby protecting the screen 10. Figure 3 In the unfolded state, the first supporting surface M1 of the first housing 21, the second supporting surface M2 of the second housing 22, and the third supporting surface M3 of the rotating mechanism 23 are coplanar and oriented in the same direction, so that the screen 10 can be reliably supported and the flatness of the screen 10 can be ensured.

[0108] The electronic device 100 provided in the embodiment of the present application can be switched between an unfolded state and a folded state. When the user uses the electronic device 100 to browse web pages, information, videos, play games, etc., the electronic device 100 can be switched from a folded state to an 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 are at an angle of 180°. Large-screen display can be achieved, and users can be provided with richer information and a better user experience can be brought to users. When the user has finished using the electronic device 100, the electronic device 100 can be switched from an unfolded state to a 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 are at an angle of 0°. In this way, the volume of the electronic device 100 can be reduced, which is convenient for the storage of the electronic device 100, and in the folded state, the screen 10 is invisible to the user, which can prevent the screen 10 from being scratched by hard objects.

[0109] 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.

[0110] In addition, it can be understood that when the electronic device 100 is a non-foldable electronic device 100, the supporting device 20 can be defined only by the first housing 21. The screen 10 can be defined only by the first screen portion 11, and in this case, the first non-display area 151 is arranged around the first display area 141.

[0111] See also Figure 4 , Figure 4 Based on Figure 3 The first housing 21 includes a first back cover 212 , a first middle frame 211 and a first insulating frame 213 .

[0112] Please continue reading Figure 4, the first back cover 212 is in a flat plate shape. For example, the first back cover 212 is in a rectangular flat plate shape or a rounded rectangular flat plate shape. Of course, in other examples, the first back cover 212 can also be in a semicircular flat plate shape, a diamond flat plate shape, an oblong flat plate shape, an elliptical shape or a special shape. The material of the first back cover 212 includes but is not limited to glass, plastic and metal.

[0113] See also Figure 5 , Figure 5 Based on Figure 4 The first middle frame 211 includes a first middle plate 2111 and a first side frame 2112 .

[0114] 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.

[0115] The first middle board 2111 includes a conductive portion 21111 and an insulating portion 21112. The conductive portion 21111 is used as a reference ground. Each circuit element in the electronic device 100 can be grounded by being electrically connected to the reference ground to avoid leakage of the circuit element and damage caused by a large current shock.

[0116] 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 setting position of the reference ground in the present application is not limited to this. In other examples, the first middle plate 2111 may not be used as a reference ground, but a part of the first frame 21121 may be used as a reference ground, or the reference ground may be directly set on the circuit board. Exemplarily, the material of the conductive part 21111 includes but is not limited to metal, such as copper, iron or aluminum. The material of the insulating part 21112 includes but is not limited to plastic.

[0117] The first side frame 2112 is arranged around the edge of the first middle plate 2111 and the first back cover 212. The first side frame 2112 is fixedly connected to the first middle plate 2111 and the first back cover 212 to define a first installation space ( Figure 5 not shown).

[0118] In some examples, the first side frame 2112 and the first middle plate 2111 are integrally formed, which is conducive to improving the connection strength between the first side frame 2112 and the first middle plate 2111, simplifying the processing technology, and reducing the assembly cost. In other examples, the connection method between the first side frame 2112 and the first middle plate 2111 includes but is not limited to gluing, welding, clamping or screw connection. This arrangement can simplify the mold structure of the first side frame 2112 and the first middle plate 2111, and facilitate the independent processing and manufacturing of the first side frame 2112 and the first middle plate 2111.

[0119] In some examples, the connection between the first side frame 2112 and the first back cover 212 includes, but is not limited to, gluing, clamping, or screw connection, etc. This arrangement can simplify the molds of the first side frame 2112 and the first back cover 212, and facilitate independent processing and manufacturing of the first side frame 2112 and the first back cover 212.

[0120] The material of the first side frame 2112 includes but is not limited to metal, plastic, and a combination of the two.

[0121] Specifically, the first side frame 2112 includes a first side wall 21122 and a first frame 21121 which are connected to the first middle plate 2111 in a circumferential direction.

[0122] The first side wall 21122 is connected between a side edge of the first middle plate 2111 adjacent to the rotating mechanism 23 and a side edge of the first back cover 212 adjacent to the rotating mechanism 23 , and the first side wall 21122 faces the rotating mechanism 23 .

[0123] See also Figure 6 , Figure 6 Based on Figure 5 The first middle frame 211 and the screen 10 shown in the figure are matched. The first frame 21121 is on the side to which the peripheral side J1 of the first screen portion 11 faces. In other words, the peripheral side J1 of the first screen portion faces the first frame 21121. The first frame 21121 is fixed to the 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.

[0124] 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 end or both ends of the first shell 21 in the Y-axis direction. Alternatively, a part of the first frame segment D1 is located at one end of the first shell 21 away from the second shell, and the other part 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. 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 specifically limit this.

[0125] 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 track of the first frame segment D1 itself, and two adjacent antenna radiators D11 are spaced apart to form a gap, which can be filled with an insulating structure D12. Exemplarily, the material of the insulating structure D12 includes but is not limited to plastic.

[0126] 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 to meet the clearance requirement of the antenna radiator D11.

[0127] For example, the insulating portion 21112 and the insulating structure D12 in the first frame segment D1 may be an integrally formed part, which is helpful to improve the connection strength between the two.

[0128] The first frame 21121 has a first end surface F1. The orientation of the first end surface F1 is consistent with the orientation of the first display surface (ie, the first non-display area 151 and the first display area 141).

[0129] See also Figure 7a and Figure 7b , Figure 7a Based on Figure 1 The partial cross-sectional structure diagram of the electronic device 100 at line AA is shown. Figure 7b Based on Figure 7aThe structure shown is an enlarged view of the circled portion at P. The first insulating frame 213 is located on the side to which the first end face F1 faces, 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 method between the first insulating frame 213 and the first frame 21121 includes but is not limited to snap connection, gluing or screw connection.

[0130] Specifically, the first insulating frame 213 and the first frame 21121 have the same extension track (combined with Figure 4 ). In the specific example of the present application, the first insulating frame 213 and the first frame 21121 both extend substantially in a "U" shape.

[0131] The material of the first insulating frame 213 includes but is not limited to plastic.

[0132] Please continue reading Figure 7a and Figure 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.

[0133] The first side portion 2132 is located on the side toward which the outer peripheral side J1 of the first screen portion 11 faces. That is, 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 one end of the first cover portion 2131 away from the center of the first display surface.

[0134] Please continue reading Figure 7a In order to facilitate the positioning and installation between the first side edge portion 2132 and the first frame 21121, a positioning step portion F2 is formed at the inner end of the first end surface F1. The other end of the first side edge portion 2132 cooperates with the positioning step portion F2.

[0135] In the 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 frame 21121 , thereby optimizing the appearance of the electronic device 100 .

[0136] Since the antenna radiator D11 is a section of the first frame 21121 along its own extension trajectory, when the first end surface F1 of the first frame 21121 is provided with a positioning step portion F2, a portion of the positioning step portion F2 is located on the antenna radiator D11. Based on this, the portion of the positioning step portion F2 located on the antenna radiator D11 is 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.

[0137] It is worth mentioning that please refer back to Figure 4 , the second housing 22 may 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, the second middle frame 221, and the second insulating frame 223 may refer to the first housing 21 in the foregoing text, and will not be described in detail in the following text. That is, the structure of the second housing 22 may be the same as that of the first housing 21. Of course, the structure of the second housing 22 may also be different from that of the first housing 21.

[0138] Please continue reading Figure 7a , the circuit board 30 is located in the first installation space Q. Specifically, the circuit board 30 can be stacked and fixed on the first middle plate 2111. Exemplarily, the circuit board 30 can be fixed to the first middle plate 2111 by gluing, welding, clamping or screw connection.

[0139] The circuit board 30 can be a hard circuit board, a flexible circuit board, or a hard-soft circuit board. For example, the circuit board 30 can be a FR-4 dielectric board, a Rogers dielectric board, or a mixed dielectric board of FR-4 and Rogers, etc. Here, FR-4 is a code for a flame retardant material grade, and the Rogers dielectric board is a high-frequency board.

[0140] In order to facilitate the circuit board 30 to control the screen 10 to display images or information, please continue to refer to Figure 7a 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 .

[0141] 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.

[0142] In some examples, the screen cable 90 is a flexible printed circuit (FPC), which can facilitate the bending of the screen cable 90 and reduce the difficulty of assembling the screen cable 90 and the circuit board 30. In other examples, the screen cable 90 can also be an enameled wire.

[0143] Specifically, the circuit board 30 includes a grounding metal layer (not shown in the figure). The grounding metal layer is electrically connected to the reference ground on the first middle plate 2111. For example, please continue to refer to Figure 7a The grounding metal layer 301 and the first middle plate 2111 can be fixed and electrically connected by a metal spring 40 .

[0144] See also Figure 8 , Figure 8 Based on Figure 7a The schematic diagram of the cross-sectional structure of the circuit board 30 shown in FIG. The circuit board 30 includes multiple metal layers 301 and multiple insulating dielectric layers 302. The metal layers 301 and the insulating dielectric layers 302 are alternately and stacked in sequence along the thickness direction (i.e., the Z-axis direction) of the circuit board 30, so that the circuit board 30 forms a multi-layer wiring structure.

[0145] 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.

[0146] Exemplarily, in order to facilitate electrical connection between the grounded metal layer and the reference ground of the first mid-board 2111, the grounded metal layer can be a metal layer 301 closest to the first mid-board 2111 among the multiple metal layers 301. Of course, the grounded metal layer can also be other metal layers 301 in the circuit board 30.

[0147] See also Fig. 9 , and combined with Figure 7a , Fig. 9 Based on Figure 7a The three-dimensional diagram of the relative position relationship between a part of the first frame segment D1 and the circuit board 30 in the electronic device 100 shown. The circuit board 30 is used to integrate the control chip. Specifically, a radio frequency chip 70 can be fixed on the circuit board 30.

[0148] 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.

[0149] In some embodiments, the RF chip 70 includes a transmitting path and a receiving path. The transmitting path includes devices such as a power amplifier and a filter, through which the signal is subjected to power amplification, filtering and other processing and then transmitted to the antenna radiator D11, and then transmitted to the outside world through the antenna 80; the receiving path includes devices such as a low-noise amplifier and a filter, through which the external signal received by the antenna 80 is subjected to low-noise amplification, filtering and other processing and then transmitted to the RF chip 70, thereby realizing the communication of one signal between the electronic device 100 and the outside world through the RF chip 70 and the antenna 80.

[0150] Antenna 80 may be an omnidirectional antenna. An omnidirectional antenna is an antenna 80 that radiates signals around antenna 80 like a spherical transmitting source, that is, the signal radiation intensity in all directions of 360° of antenna 80 is the same to achieve the best communication effect. In other examples, antenna 80 may also be a directional antenna. A directional antenna is an antenna 80 that radiates signals in a specific direction.

[0151] 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 a higher frequency or a lower frequency. This application does not make any specific limitation on this.

[0152] 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. 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. Understandably, 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, a low frequency, a strong ability to penetrate walls, and a large communication range; the 5G frequency band has a wide bandwidth, a high frequency, and a 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.

[0153] Exemplarily, the number of antennas 80 may be one or more. When there are multiple antennas 80, the multiple antennas 80 may work independently of each other or in combination. Each antenna 80 in the electronic device 100 may be used to cover a single or multiple communication frequency bands. Different antennas 80 may also be reused to improve the utilization of the antennas 80.

[0154] Please continue reading Fig. 9 , and combined with Figure 7a The antenna 80 includes the antenna radiator D11, the feeding structure 81 and the reference ground (ie, the conductive part 21111) mentioned above.

[0155] The antenna 80 may include an antenna radiator D11. Figure 1-Figure 9 In the specific example shown, the antenna 80 is described as having one antenna radiator D11. In other examples, the antenna 80 may also include multiple antenna radiators D11. Fig. 9 The antenna radiator D11 has a feeding point D111 and a grounding point D112.

[0156] Specifically, the feeding point D111 and the grounding point D112 are both located on the connecting 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.

[0157] For example, the feeding structure 81 includes but is not limited to metal connecting strips, feeding springs, microstrip lines and coaxial lines. Fig. 9 The feeding structure 81 includes a metal connection block 811 and a feeding spring 812. The metal connection block 811 is fixed to the antenna radiator D11. One end of the feeding spring 812 is fixed to the circuit board 30 and is electrically connected to the RF chip 70. The other end of the feeding spring 812 abuts against the metal connection block 811.

[0158] 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.

[0159] See also Fig.10 , and combined with Fig. 9 , Fig.10 Based on Figure 7a A three-dimensional diagram of the relative positional relationship between a portion of the first frame segment D1 and the first middle plate 2111 in the electronic device 100 shown. 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 provided on the above-mentioned insulating portion 21112. In addition, one end of the grounding connector 82 is fixed and electrically connected to the grounding point D112 of the antenna radiator D11, and the other end of the grounding connector 82 is fixed and electrically connected to the conductive portion 21111. In this way, the grounding of the antenna radiator D11 can be achieved. In other examples, the antenna 80 may also not include the grounding connector 82. It should be noted that the grounding point D112 in the present application refers to a position on the antenna radiator D11 that is directly in contact with and fixed to the grounding connector 82. When the grounding connector 82 is not provided, the grounding point D112 refers to a position on the antenna radiator D11 that is used to directly contact and fix to the reference ground.

[0160] Considering the insulation between the ground connection member 82 and other structures inside the electronic device 100, for example, please continue to refer to Fig.10 , and combined with Figure 7a The grounding connector 82 can be embedded in the insulating portion 21112. That is, the insulating portion 21112 wraps the grounding connector 82. Thus, the insulating portion 21112 is used to insulate and separate the grounding connector 82 from other structures, thereby improving the electrical connection reliability of the electronic device 100.

[0161] 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.

[0162] See also Fig.11 , Fig.11 Based on Figure 3 The schematic diagram of the screen 10 changing between the folded state and the unfolded state is shown. Since the screen 10 will be deformed when switching between the unfolded state and the folded state, there is relative sliding between the screen 10 and the first insulating frame 213 and between the screen 10 and the second insulating frame. The screen 10 and the first insulating frame 213 and between the screen 10 and the second insulating frame 223 cannot be fixed and bonded with traditional hot melt adhesive or adhesive to play an insulating role.

[0163] Please return 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. In this way, on the one hand, the relative movement between the screen 10 and the first insulating frame 213 can be facilitated, and at the same time, the sealing foam 60 can also play a certain waterproof role.

[0164] 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 often freeze, automatically shut down, have poor picture quality and volume, and have inconsistent signals. 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.

[0165] As described above, a sealing foam 60 is arranged between the first cover portion 2131 and the first non-display area 151. It can be understood by those skilled in the art that the sealing foam 60 is a porous loose structure, and its ability to resist static electricity is poor. When a user uses the electronic device 100 (for example, in winter or rubbing on one side of the screen 10), static electricity is easily accumulated on the surface of the screen 10. The static electricity on the surface of the screen 10 may enter the inside of the electronic device 100 through the pores of the sealing foam 60, and hit the screen cable 90, causing the screen 10 to fail to work, reducing the service life of the screen 10. In particular, when static electricity accumulates at the first area segment 1511, since the screen cable 90 is closer to the first area segment 1511, the static electricity hits the screen cable 90 through the pores of the sealing foam 60, causing a greater risk of failure of the screen 10.

[0166] To resolve this technical issue, see Fig.12 and Fig.13 , Fig.12 Based on Figure 4 A three-dimensional view of the first insulating frame 213 is shown. Fig.13 Based on Fig.12 Schematic diagram of the vertical projection of the electrostatic discharge structure 2133 on the first insulating frame 213 shown 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 improve the service life of the screen 10.

[0167] In other examples, the electrostatic discharge structure 2133 may also be stacked and fixed on the first region segment 1511 , as long as it is ensured that the electrostatic discharge structure 2133 is located on the side facing the first region segment 1511 .

[0168] The above technical solution has a good electrostatic protection effect. However, since the electrostatic discharge structure 2133 is arranged in parallel with the first frame segment D1, and the electrostatic discharge structure 2133 extends to the two ends of the first cover body 2131 along the extension direction of the first frame segment D1, the length is relatively long, which is much longer than the length of the antenna radiator D11. In this way, part of the electromagnetic waves radiated by the antenna radiator D11 to the surroundings will reach the electrostatic discharge structure 2133, and since the length of the electrostatic discharge structure 2133 is relatively long, the electromagnetic waves reaching the electrostatic discharge structure 2133 will be relatively large, so it is easy to form a reverse current on the electrostatic discharge structure 2133. The direction of the reverse current is opposite to the direction of the current on the antenna radiator D11. This causes the electrostatic discharge structure 2133 to reflect the electromagnetic wave, and the electromagnetic wave reflected by the electrostatic discharge structure 2133 returns to the feeding point D111 of the antenna radiator D11, and cancels the signal radiated by the antenna radiator D11, greatly reducing the radiation efficiency of the antenna radiator D11.

[0169] Here, it can be understood that the radiation efficiency of the antenna 80 refers to the ratio of the power radiated into space by the antenna 80 (i.e., the power of the electromagnetic wave part effectively converted) to the active power input to the antenna 80. Among them, the active power input to the antenna 80 = the input power of the antenna 80 - the loss of the antenna 80; the loss of the antenna 80 mainly includes the ohmic loss of the metal and / or the dielectric loss.

[0170] To solve the above problems, see Fig.14 and Fig.15 , Fig.14 Schematic diagram of the first insulating frame 213 in the electronic device 100 provided in some other embodiments of the present application. Fig.15 Based on Fig.14 The vertical projection schematic diagram of the electrostatic discharge structure 2133 on the first insulating frame 213 on the first middle frame 211 is shown. 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).

[0171] 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 surfaces of any two adjacent conductive portions 21331 facing each other face each other and have a certain distance therebetween.

[0172] In the electronic device 100 of the embodiment of the present application, the static electricity on the surface of the screen 10 can be discharged to the reference ground through the static electricity discharge structure 2133, and will not hit the screen cable of the screen 10, which is beneficial to improve the service life of the screen 10. In addition, although a part of the electromagnetic waves radiated to the surroundings by the antenna radiator D11 may reach the static electricity discharge structure 2133, since the static electricity discharge structure 2133 is defined by a plurality of spaced apart conductive parts 21331, it is beneficial to disconnect the originally relatively long entire static electricity discharge structure 2133 to form a plurality of relatively short conductive parts 213311, so that it is difficult to form a reverse current on the conductive part 21331 with a shorter length, and then it can at least reduce or avoid the reflection of the electromagnetic wave by the conductive part 21331 with a shorter length to a certain extent, which is beneficial for the electromagnetic wave to bypass the conductive part 21331 with a shorter length and radiate to the outside world, and then it is beneficial to improve the radiation efficiency of the antenna 80.

[0173] On this basis, 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 (for example, Fig.15 In the X-axis direction of the image, the conductive portion 21331 opposite to the antenna radiator D11 may be one or more. On this basis, in the conductive portion 21331 parallel to the first display surface and in the arrangement direction of the first area segment 1511 and the first frame segment D1, among the conductive portions 21331 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.

[0174] 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 .

[0175] See also Fig.16 , Fig.16 Based on Fig.15Schematic diagram of vertical projection of antenna radiator D11 and conductive part 21331 in plane F parallel to the first display surface. In plane F parallel to the first display surface, the vertical projection of antenna radiator D11 is first projection K1, and the vertical projection of conductive part 21331 is second projection K2. Among multiple second projections K2, the second projection K2 directly opposite to the first projection K1 is the target projection. That is to say, among multiple second projections K2, the projection whose vertical projection along the X-axis direction on the first projection K1 overlaps with the first projection K1 is the target projection. The target projection is the vertical projection of the conductive part 21331 on plane F opposite to antenna radiator D11 in the arrangement direction of the first area segment 1511 and the first frame segment D1, which is parallel to the first display surface. And, the "overlap" includes the following two situations. Situation 1: Part of the target projection falls into the first projection K1; Situation 2: The target projection is completely within the range of the first projection K1.

[0176] Furthermore, it can be 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 in the arrangement direction of the first area segment 1511 and the first frame segment D1. Alternatively, the conductive portion 21331 can be opposite to one of the antenna radiators D11 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, but not opposite to the remaining antenna radiators D11 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.

[0177] It is worth noting that, in the conductive portion 21331 parallel to the first display surface and in the arrangement direction of the first region segment 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:

[0178] Case 1: In a direction parallel to the first display surface and in the arrangement direction of the first region segment 1511 and the first frame segment D1, there is one conductive portion 21331 opposite to the antenna radiator D11, and the length of the one conductive portion 21331 is less than twice the length of the antenna radiator D11.

[0179] Situation 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 parts 21331 opposite to the antenna radiator D11, and the lengths of some of the multiple conductive parts 21331 are less than twice the length of the antenna radiator D11, and the lengths of other conductive parts 21331 are equal to or greater than twice the length of the antenna radiator D11.

[0180] Case 3: In a direction parallel to the first display surface and in the arrangement direction of the first region segment 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 .

[0181] Since the length of at least one of the conductive parts 21331 that is 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 to 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.

[0182] On this basis, in some embodiments, in the conductive portion 21331 parallel to the first display surface and in the arrangement direction of the first area segment 1511 and the first frame segment D1, opposite to the antenna radiator D11, 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, and then helping to improve the radiation efficiency of the antenna 80 at least to a certain extent.

[0183] For some specific examples, see Figure 15-16 In order to further improve the radiation efficiency of the antenna 80, 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, the length of the conductive portion 21331 opposite to the antenna radiator D11 is smaller than the length of the antenna radiator D11.

[0184] 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.

[0185] Exemplarily, the electrostatic discharge structure 2133 may be a coating or plating layer attached 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 may also be made of a sheet. The sheet is fixed to the first cover portion 2131 by gluing.

[0186] On this basis, for some specific examples, please continue to refer to Figure 15-16 In order to further improve the radiation efficiency of the antenna 80 and simplify the processing technology of the electrostatic discharge structure 2133, the number of the conductive parts 21331 opposite to the antenna radiator D11 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 is in the range of 2 to 5. Exemplarily, 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 number of the conductive parts 21331 opposite to the antenna radiator D11 is 2, 3 or 4.

[0187] In this way, it is helpful to set the length of the conductive part 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 to be shorter, so as to prevent the formation of reverse current on the conductive part 21331 to a large extent, thereby reducing or avoiding the reflection of electromagnetic waves by the conductive part 21331 to a large extent, and making the electromagnetic waves bypass the conductive part 21331 to radiate to the outside to a large extent, thereby further improving the radiation efficiency of the antenna 80. In addition, compared with setting more conductive parts 21331, it is helpful to simplify the processing technology of the electrostatic discharge structure 2133, improve processing efficiency, and reduce processing costs.

[0188] On the basis of the above embodiment, in order to realize the electrical connection between the electrostatic discharge structure 2133 and the reference ground, please continue to refer to Fig.14 and Fig.15, at least one of the multiple conductive parts 21331 is a first conductive part 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. And the remaining portion of the electrostatic conductor 21321 is located on an end surface of the first side portion 2132 that is away from the first display surface. One first conductive part 2133a corresponds to one electrostatic conductor 21321. The first conductive part 2133a is fixed and electrically connected to the electrostatic conductor 21321. In this way, the setting of the electrostatic conductor 21321 is conducive to the first conductive part 2133a to discharge static electricity to the reference ground through the electrostatic conductor 21321.

[0189] It can be understood that in other examples, the electrostatic conductor 21321 can also be entirely located on the surface of the outer peripheral side surface 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 surface J1 of the first side portion 2132 facing the first screen portion 11.

[0190] 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 .

[0191] Please continue reading Fig.14 and Fig.15 , the first conductive part 2133a can be multiple, when the first conductive part 2133a is multiple, the electrostatic conductor 21321 is also multiple, and the multiple electrostatic conductors 21321 correspond to the multiple first conductive parts 2133a one by one. Of course, in other examples, the first conductive part 2133a can also be one, in which case, the electrostatic conductor 21321 is also one.

[0192] 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 Fig.14 and Fig.15 , the first conductive portion 2133a includes a first sub-conductive portion 2133a1 and a second sub-conductive portion 2133a2.

[0193] 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 track of the first sub-conductive portion 2133a1 includes but is not limited to a straight line, a curve or a broken line.

[0194] The second sub-conductive portion 2133a2 is located between the electrostatic conductor 21321 and the first sub-conductive portion 2133a1. The second sub-conductive portion 2133a2 is fixed and electrically connected between the electrostatic conductor 21321 and the first sub-conductive portion 2133a1. In this way, there is a shorter electrostatic discharge path between the electrostatic conductor 21321 and the first sub-conductive portion 2133a1.

[0195] Exemplarily, the second sub-conductive portion 2133a2 and the first sub-conductive portion 2133a1 are formed as an integral part, which is helpful to simplify the processing technology between the two and reduce the manufacturing cost.

[0196] In some embodiments, in order to reduce the influence of the electrostatic conductor 21321 on the radiation efficiency of the antenna 80, the electrostatic conductor 21321 is arranged in the spacing direction of the plurality of conductive portions 21331 (ie, the extending direction of the first region segment 1511, for example Fig.15 The size of the second sub-conductive portion 2133a2 in the Y-axis direction (in the Y-axis direction) is less than or equal to the size of the second sub-conductive portion 2133a2 in the spacing direction of the plurality of conductive portions 21331. Of course, it can be understood that in other examples, the size of the electrostatic conductor 21321 in the spacing direction of the plurality of conductive portions 21331 may also be greater than the size of the second sub-conductive portion 2133a2 in the spacing direction of the plurality of conductive portions 21331.

[0197] 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.

[0198] Exemplarily, the ratio of the size of the second sub-conductive portion 2133a2 in the spacing direction of the plurality of conductive portions 21331 to the size of the first sub-conductive portion 2133a1 in the spacing direction of the plurality of conductive portions 21331 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 2133a2 in the spacing direction of the plurality of conductive portions 21331 to the size of the first sub-conductive portion 2133a1 in the spacing direction of 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.

[0199] 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 portions 21331 may also be equal to the size of the first sub-conductive portion 2133a1 in the spacing direction of the multiple conductive portions 21331 .

[0200] On this basis, since the first side portion 2132 cooperates with the positioning step portion F2, the electrostatic conductor 21321 and the positioning step portion F2 are opposite in the Z-axis direction. At the same time, since the antenna radiator D11 is grounded, and there is an electrical connection between the antenna radiator D11 and the circuit board 30, and the circuit board 30 is designed with a grounding metal layer. In this way, if the electrostatic conductor 21321 and the connection portion F3 of the antenna radiator D11 are directly opposite in the Z-axis direction and electrically connected. Therefore, the connection portion F3 can be used as a part of the electrostatic discharge path, which is conducive to using the connection portion F3 to discharge static electricity to the reference ground, thereby achieving the purpose of shortening the electrostatic discharge path.

[0201] It should be noted that the "electrical connection" between the electrostatic conductor 21321 and the connection part F3 can be a coupled feeding electrical connection. It can also be that a conductive glue is provided between the connection part F3 and the electrostatic conductor 21321 to achieve a physical electrical connection between the two. It should also be noted that coupled feeding refers to the conduction of electrical energy by coupling between two circuit elements or circuit networks that are not in contact but have a certain small distance in the field of communication.

[0202] Based on the embodiment in which the electrostatic conductor 21321 and the connecting portion F3 are facing each other 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, in order to further shorten the electrostatic discharge path, please refer to Fig.17 , and combined with Fig.15 , Fig.17 Based on Fig.15 The schematic diagram of the positional relationship between a portion of the first frame segment D1 and the circuit board 30 is shown. The electrostatic conductor 21321 includes a first type of electrostatic conductor N. The first conductive portion 2133a fixed and electrically connected to the first type of electrostatic conductor N is a first type of conductive portion. Fig.17 In FIG. 1 , the vertical projection of the first type of electrostatic conductor N on the connection portion F3 is region N'. The first type of electrostatic conductor N is directly opposite to the grounding point D112 in the Z-axis direction. In this way, the static electricity on the first type of conductive part can be discharged to the reference ground through the first type of electrostatic conductor N, the grounding point D112 and the grounding connector 82 in sequence, and the entire static electricity discharge path is relatively short.

[0203] 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 to Fig.14 and Fig.15, among the plurality of conductive parts 21331, except the first conductive part 2133a, at least one of the other conductive parts 21331 is a second conductive part 2133b. Exemplarily, among the plurality of conductive parts 21331, except the first conductive part 2133a, each of the other conductive parts 21331 is a second conductive part 2133b. Of course, it is understood that the conductive part 21331 may not include the second conductive part 2133b.

[0204] The second conductive portion 2133b is spaced apart from the electrostatic conductor 21321 on the first insulating frame 213 and there is no direct physical connection between the two. The second conductive portion 2133b discharges static electricity to the first conductive portion 2133a which is closest to the second conductive portion 2133b.

[0205] 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 can conduct static electricity and does not deteriorate the radiation efficiency of the antenna 80 or has a negligible effect on the radiation frequency of the antenna 80. In this way, when static electricity accumulates at the second conductive portion 2133b, it is beneficial for the static electricity to be conducted to the first conductive portion 2133a closest to the second conductive portion 2133b via the second conductive portion 2133b, thereby facilitating the design of the positions of the first conductive portion 2133a and the second conductive portion 2133b according to the structural layout of the electronic device 100, and optimizing the static electricity discharge path of the static electricity discharge structure 2133.

[0206] Exemplarily, there may be one or more second conductive parts 2133b. The extension track of the second conductive part 2133b includes but is not limited to a straight line, a curve or a broken line.

[0207] On this basis, in order to facilitate the discharge of static electricity at the second conductive portion 2133b to the first conductive portion 2133a, please continue to refer to Fig.14 and Fig.15 , in the spacing direction of the plurality of conductive portions 21331, at least one side of each second conductive portion 2133b is provided with a first conductive portion 2133a adjacent to the second conductive portion 2133b. That is, in the spacing direction of the plurality of conductive portions 21331, the first conductive portion 2133a adjacent to the second conductive portion 2133b may be provided on one side of each second conductive portion 2133b in the Y-axis direction, or the first conductive portion 2133a adjacent to the second conductive portion 2133b may be provided on both sides of each second conductive portion 2133b in the spacing direction of the plurality of conductive portions 21331.

[0208] It should be noted that the “adjacent” in “in the spacing direction of the plurality of conductive portions 21331, at least one side of each second conductive portion 2133b is arranged with a first conductive portion 2133a adjacent to the second conductive portion 2133b” refers to the conductive portion 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.

[0209] For example, please refer to Fig.14 and Fig.15 , the second conductive part 2133b and the first conductive part 2133a are both multiple. 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 Fig.18 , Fig.18 Schematic diagram of 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.

[0210] Based on the above embodiment of "in the spacing direction of the plurality of conductive portions 21331, at least one side of each second conductive portion 2133b is arranged with a first conductive portion 2133a adjacent to the second conductive portion 2133b", please continue to refer to Figure 14-15 as well as Fig.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. The air gap H is configured to couple the two conductive portions 21331 to be electrically connected. Such a design can ensure the conduction of static electricity without affecting the radiation efficiency of the antenna 80, and has a simple structure and is easy to manufacture.

[0211] On this basis, in order to improve the reliability of coupling 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 0.5mm. For example, the air gap H is less than 0.05mm. Exemplarily, the size of the air gap H is 0.035mm, 0.038mm, 0.04mm, 0.042mm, 0.045mm or 0.048mm.

[0212] See also Fig.19 , Fig.19 Schematic diagram of a vertical projection of an electrostatic discharge structure 2133 in an electronic device 100 on the first middle frame 211 provided in some other embodiments of the present application. Fig.15The difference of the embodiment shown is that: in this embodiment, the second conductive portion 2133b and the first conductive portion 2133a adjacent to the second conductive portion 2133b are no longer electrically connected by coupling feeding. The second conductive portion 2133b and the first conductive portion 2133a adjacent to the second conductive portion 2133b are electrically connected by the inductance structure G1. Specifically, the inductance structure G1 can be fixed on the surface of the first cover portion 2131, or fixed to the first region 1511. The inductance of the inductance structure G1 ranges from 1nH to 100nH.

[0213] Specifically, since the operating frequency of the antenna 80 is often in the gigahertz range, which is a high frequency, and the frequency of static electricity is generally tens of megahertz, which is a low frequency, the frequencies of the two are of completely different orders of magnitude. In this way, the inductance structure G1 with an inductance value range of 1nH to 100nH is close to a short circuit for static electricity, and close to an open circuit for the antenna 80. In this way, when static electricity accumulates at the second conductive portion 2133b, the static electricity can be conducted through the second conductive portion 2133b to the first conductive portion 2133a that is closest to the second conductive portion 2133b, which can ensure the conduction of static electricity without affecting the radiation efficiency of the antenna 80.

[0214] 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.

[0215] On this basis, in some embodiments, in order to further improve the reliability of electrostatic conduction of the inductor structure G1 while ensuring the radiation efficiency of the antenna 80, when the operating frequency of the antenna 80 is 1.5 GHz to 6 GHz, the inductance of the inductor structure G1 is 1 to 20 nH.

[0216] Exemplarily, the inductor structure G1 can be a metal serpentine fixed to the first cover body 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 reduce the thickness of the electronic device 100, and realize the compactness of the structure of the electronic device 100. In addition, the structure is simple, easy to process and manufacture, and the cost is low. Exemplarily, the material of the metal serpentine and the electrostatic discharge structure 2133 can be the same. In this way, selecting a material to process the metal serpentine and the electrostatic discharge structure 2133 is beneficial to improve the reliability of the electrical connection between the two. Of course, it is understandable that in other examples, the material of the metal serpentine and the electrostatic discharge structure 2133 may also be different.

[0217] On this basis, in some embodiments, the metal serpentine wire and the conductive part 21331 connected to the metal serpentine wire can be an integrally formed part. This is conducive to simplifying the processing technology between the electrostatic discharge structure 2133 and the metal serpentine wire, improving the processing efficiency, and also improving the connection reliability between the metal serpentine wire and the electrostatic discharge structure 2133.

[0218] See also Fig. 20 , Fig. 20 Schematic diagram of vertical projection of the electrostatic discharge structure 2133 in the electronic device 100 on the first middle frame 211 provided in other embodiments of the present application. Fig.19 The difference of the embodiment shown is that the second conductive part 2133b and the first conductive part 2133a adjacent to the second conductive part 2133b are no longer electrically connected through the inductor structure G1, but are electrically connected through the electrostatic protection device G2.

[0219] In some embodiments, the electrostatic protection device G2 has a breakdown voltage, and when the voltage discharged to the electrostatic protection device is greater than the breakdown voltage, the electrostatic protection device G2 is turned on. Since the voltage of static electricity is often high voltage, and the voltage of the antenna 80 is often low voltage. Therefore, when the voltage of static electricity at the second conductive part 2133b is greater than the breakdown voltage, the electrostatic protection device G2 will electrically conduct the second conductive part 2133b and the first conductive part 2133a adjacent to the second conductive part 2133b, thereby discharging static electricity to the first conductive part 2133a.

[0220] Exemplarily, the electrostatic protection device G2 can be a transient voltage suppressor diode (TVS). TVS is a high-performance protection device. When the second conductive part 2133b does not accumulate static electricity, the TVS is in a cut-off state (high resistance state); when the second conductive part 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, and discharges the static electricity to the first conductive part 2133a.

[0221] As another example, the electrostatic protection device G2 can also be a varistor, for example, a thin film varistor. A varistor is a nonlinear resistor element, which refers to a voltage-limiting element that is sensitive to voltage changes. The resistance of a varistor is related to the magnitude of the voltage applied at both ends. When the second conductive portion 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. When static electricity accumulates on the surface of the second conductive portion 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 quickly, so that the varistor is in a conducting state, and the static electricity is discharged to the first conductive portion 2133a.

[0222] Due to the arrangement position of the ground point D112 on the antenna radiator D11, not all first-type electrostatic conductors N can be directly opposite to the ground point D112 in the Z-axis direction. In order to ensure that each first conductive portion 2133a has an electrostatic discharge path with the reference ground to improve the electrostatic discharge effect, please refer to Fig.21 and Fig. 22 .in, Fig.21 This is a schematic diagram of the positional relationship between a portion of the first frame segment D1 in the electronic device 100 and the circuit board 30 provided in some other embodiments of the present application. Fig. 22 Based on Fig.21 The electrostatic discharge structure 2133 in the electronic device 100 is vertically projected on the first middle frame 211. The electrostatic conductor 21321 also includes a second type of electrostatic conductor M. The first conductive portion 2133a corresponding to the second type of electrostatic conductor M is a second type of conductive portion. Fig.21 and Fig. 22 In FIG. 1 , the vertical projection of the second type electrostatic conductor M on the connection portion F3 is the position indicated by the region M′. The second type electrostatic conductor M is directly opposite to the feeding point D111 in the thickness direction of the first screen portion 11 .

[0223] See also Fig.23 , Fig.23 Based on Fig.21 The electronic device 100 is a schematic diagram of electrical connections. The electronic device 100 also includes an electronic device. The electronic device is fixed to the circuit board. Fig.23 In the specific example shown, the electronic device is an inductor V1. The inductor V1 and the radio frequency chip 70 are connected in parallel between the feeding structure 81 and the ground metal layer. The inductance of the inductor V1 ranges from 1nH to 100nH.

[0224] Specifically, since the operating frequency of the antenna 80 is often in the gigahertz range, which is a high frequency, and the frequency of static electricity is generally tens of megahertz, which is a low frequency. The inductor V1 with an inductance value ranging from 1nH to 100nH is close to a short circuit for static electricity, and close to an open circuit for the antenna 80. In this way, when static electricity is discharged from the second type of static electricity conductor M to the feeding point D111, the static electricity can be discharged to the grounded metal layer through the inductor V1. At the same time, the inductor V1 will not deteriorate the radiation efficiency of the antenna 80, which is conducive to adjusting the resonance of the antenna 80 at least to a certain extent.

[0225] 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.

[0226] 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.

[0227] 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 understandable that the electrostatic conductor 21321 may also only include the first type of electrostatic conductor N or the second type of electrostatic conductor M. Similarly, the first conductive portion 2133a only includes the first type of conductive portion or the second type of conductive portion.

[0228] See also Fig.24 , Fig.24 FIG. 1 is a schematic diagram of electrical connections of an electronic device 100 in some other possible embodiments of the present application. Fig.23 The difference of the embodiment shown is that the electronic device is an electrostatic protection device V2 . The electrostatic protection device V2 and the radio frequency chip 70 are connected in parallel between the feeding structure 81 and the grounding metal layer 301 .

[0229] Exemplarily, the electrostatic protection device V2 has a breakdown voltage, and 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 voltage, and the voltage of the antenna 80 is often low voltage. Therefore, when the electrostatic voltage discharged to the feeding point is greater than the breakdown voltage, the electrostatic protection device V2 will be electrically turned on and discharge the static electricity to the ground metal layer 301.

[0230] Exemplarily, 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 in the previous text and will not be described again here.
