Description

[0001] This application is a divisional application of the application for patent with application number 202110873589.6, application date of 2021-07-30, and invention name of "an electronic device", which is filed with the China Patent Office. TECHNICAL FIELD

[0002] The present application relates to the technical field of NFC antenna, in particular to an electronic device. BACKGROUND

[0003] The development trend of the electronic device is that the camera module is getting larger and larger, and the number of cameras is getting more and more. Based on this, the area of the back cover occupied by the camera support will also become larger and larger.

[0004] The form of the near field communication (NFC) antenna is divided into two kinds, one of which is multiplexed with other antennas, and the other is a separate NFC antenna. For the separate NFC antenna, there are two kinds of more mainstream arrangement schemes at present, one of which is to surround the camera support for one turn, and the other is to be arranged side by side with the camera support on the back cover of the electronic device. However, with the increase of the area of the back cover occupied by the camera support, the first arrangement scheme will make the NFC antenna unable to be wired, and the second scheme will make the arrangement area of the NFC antenna be reduced, and both of the two arrangement schemes cannot guarantee the radiation performance of the NFC antenna. SUMMARY

[0005] In order to solve the problem that the existing arrangement scheme of the NFC antenna cannot guarantee the radiation performance of the NFC antenna, the present application provides an electronic device, which can still have good radiation performance of the NFC antenna in the scene that the number of cameras is getting more and more and the camera support is getting larger and larger.

[0006] The present application provides an electronic device. The electronic device comprises a back cover, a camera support, and an NFC antenna. The camera support is arranged on the back cover and comprises a first surface and a second surface arranged oppositely. The first surface of the camera support faces the outer side of the electronic device. The camera support is provided with a first light passing hole, and the first light passing hole is used to be opposite to a first flash or a first camera. The NFC antenna is laid on the first surface of the camera support. The first orthographic projection of the NFC antenna on the first surface of the camera support falls into the first surface of the camera support, and does not overlap with the first light passing hole, so as to avoid the first light passing hole.

[0007] In this embodiment, the first orthographic projection of the NFC antenna on the first surface of the camera support falls within the first surface, that is, the NFC antenna is laid in the first surface. With the increase of the number of cameras, the camera support arranged on the back cover will also increase, and the area of the first surface will also increase accordingly. Compared with the case where the area of the first surface is small, the area of the region surrounded by the NFC antenna in the same relative position laid in the first surface will also increase with the increase of the area of the first surface. It should be noted that the radiation performance of the NFC antenna is positively correlated with the area of the region surrounded by the NFC antenna, and therefore, when the area of the region surrounded by the NFC antenna increases, the radiation performance of the NFC antenna is improved.

[0008] In addition, since the camera support is the back cover of the electronic device itself, it is not in the stacking path of the display screen to the back cover of the electronic device, and its thickness is usually not considered as a factor for thinning the electronic device. Therefore, laying the NFC antenna in the first surface is not in the stacking path of the display screen to the back cover of the electronic device, and the NFC antenna will not become a bottleneck for thinning the electronic device.

[0009] Optionally, the number of the first light transmission holes is a plurality, and the plurality of first light transmission holes are arranged in a ring array on the camera support. It should be understood that when the camera support has a plurality of first light transmission holes, the size of the camera support is large, and therefore the area of the first surface is large. Based on this, the area of the region surrounded by the NFC antenna laid in the first surface can be guaranteed, and therefore the radiation performance of the NFC antenna can be guaranteed.

[0010] In a possible design, the NFC antenna is provided with a ferrite and a metal wire running along the edge of the ferrite. The area of the metal wire on the first orthographic projection is a wire projection area, and the wire projection area is annular. The first light transmission hole is located inside the annular corresponding to the wire projection area.

[0011] In this design, the wire projection area is annular, and therefore the metal wire is also annular. Since the first light transmission holes are all located inside the annular corresponding to the wire projection area, the metal wire is laid between the first light transmission hole and the edge of the camera support, and the first light transmission hole is surrounded by the metal wire. It can be seen that the metal wire is an annular located between the first light transmission hole and the edge of the camera support. With the increase of the number of cameras, the number of first light transmission holes increases, and the camera support also increases, thereby causing the area of the first surface to increase accordingly. It should be understood that when the area of the first surface increases, the area of any annular located between the first light transmission hole and the edge of the camera support will also increase. Based on this, the wire area of the metal wire (which is an annular located between the first light transmission hole and the edge of the camera support) is improved, and therefore the radiation performance of the NFC antenna is improved.

[0012] Optionally, the minimum distance between the edge line of the first light passing hole and the edge line of the camera holder is greater than a first threshold. The first threshold is at least the width of the metal trace. In this way, the first light passing hole and the camera holder edge have enough space to lay the NFC antenna, ensuring the radiation performance of the NFC antenna.

[0013] Another possible design, the NFC antenna is provided with a ferrite, and a metal trace along the edge of the ferrite. The area of the metal trace in the first projection is the trace projection area, which is annular. The first light passing hole is located outside the annular corresponding to the trace projection area.

[0014] In this design, the trace projection area is annular, so the metal trace is also annular. Since the first light passing hole is located outside the annular corresponding to the trace projection area, the metal trace is laid in the position within the array path of the first light passing hole. It can be seen that the metal trace is an annular located within the array path of the first light passing hole. As the number of cameras increases, the number of first light passing holes increases, and the camera holder also increases, resulting in the area of the first surface increasing accordingly. It should be understood that when the area of the first surface increases, the area of any annular located within the array path of the first light passing hole will also increase. Based on this, the trace area of the metal trace (which is an annular located within the array path of the first light passing hole) is improved, thereby improving the radiation performance of the NFC antenna.

[0015] Optionally, the minimum distance between the edge line of the first light passing hole and the edge line of the camera holder is less than a second threshold. The second threshold is at least the width of the metal trace. In this case, the space between the first light passing hole and the camera holder edge is small, which is not enough to lay the NFC antenna. It should be understood that when the overall structure of the camera holder is large and the space between the first light passing hole and the camera holder edge is small, the area within the array path of the first light passing hole will necessarily be large. In this case, the scheme of laying the metal trace in the position within the array path of the first light passing hole can be implemented in this scenario to ensure the radiation performance of the NFC antenna.

[0016] Optionally, the two first light passing holes adjacent to each other in the array path are respectively a first adjacent hole and a second adjacent hole. The NFC antenna has an extension area extending in a first direction, the first direction away from the geometric center of the camera holder and towards between the first adjacent hole and the second adjacent hole. In this embodiment, the existence of the extension area makes the NFC antenna harvest the area of the region surrounded by the metal trace in the extension area, so the radiation performance of the NFC antenna is improved.

[0017] As an optional embodiment, the interval of the first adjacent hole and the second adjacent hole in the array direction is greater than a third threshold value, and the third threshold value is at least three times the width of the metal trace. The part of the metal trace in the extension region includes the first trace and the second trace. The first trace and the second trace both extend in the second direction and pass through the position between the first adjacent hole and the second adjacent hole. The first trace and the second trace are spaced apart in a third direction. The third direction is the array direction of the first adjacent hole and the second adjacent hole, and the second direction is perpendicular to the third direction.

[0018] It should be noted that only when the trace area of the metal trace in the extension region is large enough, the radiation performance of the NFC antenna can be greatly improved by the extension region, and the existence of the extension region is meaningful.

[0019] In the embodiment, when the interval of the first adjacent hole and the second adjacent hole in the array direction is greater than the third threshold value, it means that the interval between the first adjacent hole and the second adjacent hole is large. In this case, the first trace and the second trace passing through the position between the first adjacent hole and the second adjacent hole can maintain a large interval to obtain a large enough trace area. In addition, the first trace and the second trace both extend in the second direction, and can maintain the same interval with the first adjacent hole and the second adjacent hole respectively. On the one hand, it can be more beautiful, and on the other hand, it can avoid the problem that one side has a large interval and the other side has a small interval which is not easy to process. Moreover, the first trace and the second trace maintain an interval in the third direction. Since the trace area of the metal trace is determined by the area surrounded by the metal trace, when the first trace and the second trace have an interval in the third direction, the trace area can be obtained by the extension region, and the existence of the extension region is meaningful.

[0020] As another optional embodiment, the interval of the first adjacent hole and the second adjacent hole in the array direction is less than a fourth threshold value, and the fourth threshold value is at least three times the width of the metal trace. The part of the metal trace in the extension region includes the first trace and the second trace. The first trace and the second trace gradually approach in the second direction, and the second direction is perpendicular to the array direction of the first adjacent hole and the second adjacent hole.

[0021] It is to be noted that when the interval between the first adjacent hole and the second adjacent hole in the array direction is less than the fourth threshold, it means that the interval between the first adjacent hole and the second adjacent hole is not large. In this case, if the first trace and the second trace both extend towards the second direction, the interval between the first trace and the second trace is also small, and thus the trace difficulty is high and the processing technology requirement is extremely high. In addition, the interval between the first trace and the second trace is small, and the trace area gain that can be obtained is small. It is undoubtedly a waste to harvest a small trace area under a difficult processing technology. Based on this, in the embodiment, the first trace and the second trace are in a gradually converging state in the second direction, and will not be difficult to trace due to the interval between the first adjacent hole and the second adjacent hole in the array direction not being large. In addition, compared with the scheme without the extension region, the embodiment can harvest the trace area of the metal trace in the extension region, so as to improve the radiation performance of the NFC antenna.

[0022] In another possible design scheme, a ferrite is arranged on the NFC antenna, and a metal trace extends along the edge of the ferrite. The area of the metal trace in the first orthographic projection is a trace projection area, and the trace projection area is annular. Part of the plurality of first light transmission holes is located outside the annular corresponding to the trace projection area, and the remaining part of the plurality of first light transmission holes is located inside the annular corresponding to the trace projection area.

[0023] Since the first light transmission hole can be used to mount a camera, a flash, or a sensor, different first light transmission holes can mount different devices, and the sizes of the devices can be inconsistent, so there can be a case that the space between part of the first light transmission holes and the edge of the camera support is small, and the space between part of the first light transmission holes and the edge of the camera support is large. For the first light transmission hole with a small space between the camera support edge, it is located inside the annular corresponding to the trace projection area, that is, it is surrounded inside by the metal trace. For the first light transmission hole with a large space between the camera support edge, it is located outside the annular corresponding to the trace projection area, that is, it is located outside the metal trace. It can be seen that in the embodiment, the position between the first light transmission hole and the edge of the camera support that can be traced is fully utilized for tracing, and the trace area is maximized, so as to improve the radiation performance of the NFC antenna.

[0024] For example, when the minimum interval between the edge line of the first light transmission hole and the edge line of the camera support is less than the first threshold, the first light transmission hole is located outside the annular corresponding to the trace projection area. The first threshold is at least the trace width of the metal trace. When the minimum interval between the edge line of the first light transmission hole and the edge line of the camera support is greater than the first threshold, the first light transmission hole is located inside the annular corresponding to the trace projection area.

[0025] In the example, when the minimum distance between the edge line of the first light transmission hole and the edge line of the camera support is less than the first threshold value, it can be considered that the space between the first light transmission hole and the edge of the camera support is small, and the metal wire cannot be routed from this position; when the minimum distance between the edge line of the first light transmission hole and the edge line of the camera support is greater than the first threshold value, it can be considered that the space between the first light transmission hole and the edge of the camera support is large, and the metal wire can be routed from this position, so as to surround the first through hole inside and obtain the area benefit of this part.

[0026] Optionally, the NFC is provided with a relief hole, and a region of the relief hole on the first orthographic projection is a relief region. The relief region is located inside a ring corresponding to the wire projection region. The camera support is further provided with a second light transmission hole. The second light transmission hole overlaps the relief region, and the second light transmission hole is used to face the second flash, the second sensor, or the second camera.

[0027] In the embodiment, the relief region overlaps the second light transmission hole, that is, the second light transmission hole is provided in the region of the camera support facing the relief hole. It should be understood that the relief region is located inside a ring corresponding to the wire projection region, which represents a region inside the metal wire in which the relief hole is provided. The provision of the relief hole does not affect the wire area of the metal wire, so as to not affect the radiation performance of the NFC antenna. Under the premise of ensuring the radiation performance of the NFC antenna, the embodiment provides one more light transmission hole without increasing the size of the camera support, so as to support the installation of one more camera, which is conducive to meeting the trend of increasing the number of cameras.

[0028] Optionally, the electronic device further includes a decorative lens. An edge of the first surface of the camera support is provided with a back adhesive area, and the decorative lens is fixed to the first surface of the camera support by being connected to the back adhesive area. The NFC antenna is arranged between the decorative lens and the first surface of the camera support, and the first orthographic projection and the back adhesive area do not overlap. In the embodiment, the decorative lens can protect and beautify the camera. The first orthographic projection and the back adhesive area do not overlap, that is, the NFC antenna needs to avoid the back adhesive area to avoid warping due to the NFC antenna when the decorative lens is installed, so as to achieve good adhesion and sealing.

DETAILED DESCRIPTION

[0030] In the embodiments of the present application, the terms "first", "second", "third" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second", "third" can explicitly or implicitly include one or more of the features.

[0031] In the embodiments of the present application, "and / or" is only a description of the association relationship between the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0032] In the embodiments of the present application, "annular" refers to the shape obtained after extending a predetermined distance inward from the outer edge with a predetermined shape to form an inner edge. Based on this, the annular has an outer edge line and an inner edge line, the annular inside refers to the area inside the annular inner edge line, and the annular outside refers to the area outside the annular outer edge line, which will not be described again. It should be understood that in the embodiments of the present application, the annular can be a circular ring, or a non-circular ring, for example, a square annular, a polygonal annular, etc.

[0033] With the development of technology, electronic devices such as mobile phones, tablets, and laptops generally have NFC functions to realize mobile payment and other functions. The radiation performance of the NFC antenna plays a crucial role in the NFC function.

[0034] It should be noted that the NFC antenna includes ferrite and metal traces. The metal traces are used for electromagnetic wave radiation, and the ferrite is used to reduce the risk of mutual interference of the NFC antenna and other electronic components (such as various devices on the mainboard) of the electronic device to form eddy current. The ferrite includes two opposite surfaces, and the metal traces are laid along the edge of the ferrite on one of the surfaces of the ferrite. The radiation performance of the NFC antenna is mainly affected by the area (hereinafter referred to as the trace area) of the area (hereinafter referred to as the trace area) surrounded by the metal traces, and is basically not affected by whether the ferrite exists in the trace area. The greater the trace area, the better the radiation performance of the NFC antenna. Whether the ferrite exists in the trace area affects the anti-interference effect of the NFC antenna.

[0035] As shown in Figure 1 , in (a) of Figure 1 , the NFC antenna 30 includes ferrite 31 and metal traces 32 along the edge of the ferrite 31. Among them, the trace area of the metal traces 32 is area A1. Different from (a) of Figure 1 , in (b) of Figure 1 , the trace area of the metal traces 32 is area B1. Different from (a) of Figure 1 , in (c) of Figure 1 , the trace area of the metal traces 32 is area C1. By comparing (a) and (b) of Figure 1 , it can be seen that the trace area of the trace area A1 is greater than the trace area of the trace area B1, and the radiation performance of the NFC antenna shown in (a) of Figure 1 is better; by comparing (b) and (c) of Figure 1 , it can be seen that there is no ferrite in the trace area A1, and there is ferrite in the trace area C1, but since the trace area of the trace area A1 and the trace area of the trace area C1 are the same, the radiation performance of the NFC antenna shown in (a) of Figure 2 is roughly the same.

[0036] Based on this, how to ensure the trace area of the NFC antenna, and how to obtain the maximum trace area benefit in a limited space, is crucial to ensure the radiation performance of the NFC antenna.

[0037] Please refer to Figure 2 , Figure 2This is a schematic diagram illustrating the arrangement of the NFC antenna on an electronic device in one possible design. The electronic device includes a back cover 10, a camera bracket 20, and an NFC antenna 30. Both the camera bracket 20 and the NFC antenna 30 are mounted on the back cover 10. The camera bracket 20 is used to mount the camera of the electronic device. In some embodiments, if the electronic device includes a flash or sensor, the camera bracket 20 is also used to mount the flash or sensor. It should be understood that "mounting" here means that the camera bracket 20 needs to have a certain cooperative relationship with the camera, flash, or sensor, and does not necessarily mean that there is a direct connection between the camera, flash, or sensor and the camera bracket 20. For example, the light-transmitting hole on the camera bracket may be directly opposite the camera. Of course, in other embodiments, there may also be a connection relationship, which is not specifically limited in this application.

[0038] On the one hand, the camera bracket 20 can serve to decorate the camera, flash, or sensor; on the other hand, it can protect the camera, flash, or sensor from damage. For example... Figure 2 As shown, the NFC antenna 30 is distributed circumferentially along the camera bracket 20 and surrounds the outside of the camera bracket 20.

[0039] In this design, as the area occupied by the camera bracket 20 on the back cover 10 increases, the trace area of ​​the NFC antenna 30 also increases. However, due to the limited internal space of the electronic device, when the trace area of ​​the NFC antenna 30 increases, the laying of the metal traces of the NFC antenna 30 will be blocked by other components inside the electronic device (such as the battery), thus preventing the traces from being laid. In other words, Figure 3 The design shown cannot support the laying of NFC antenna 30 with a large wiring area. In scenarios where the area of ​​camera bracket 20 is too large, other methods need to be sought to ensure the wiring area of ​​NFC antenna 30 in order to ensure the radiation performance of NFC antenna 30.

[0040] Please see Figure 3 , Figure 2 For the section line AA Figure 4 The diagram shows a cross-sectional view of the electronic device obtained by cutting it. The electronic device includes a back cover 10, a mid-frame 50, and a display screen 40. The display screen 40 and the back cover 10 are respectively disposed on opposite sides of the mid-frame 50, forming a cavity. A motherboard 60, a motherboard bracket 70 for supporting the motherboard 60, and an NFC antenna 30 are stacked within the cavity. It can be seen that the NFC antenna 30 is a component along the thickness direction of the electronic device. With the popularity of ultra-thin electronic devices, the thickness of the NFC antenna 30 is also one of the bottlenecks in the overall thinning of the device.

[0041] Please see Figure 4 , Figure 2This is a schematic diagram showing the placement of the NFC antenna in another possible design. (Different from...) Figure 3 and Figure 4 In the illustrated scheme, the camera bracket 20 and the NFC antenna 30 are arranged side by side on the back cover 10 of the electronic device, with the NFC antenna 30 located on the side of the camera bracket 20.

[0042] In this design, when the area occupied by the camera bracket 20 on the back cover 10 increases, the usable space for the NFC antenna 30 will be reduced. Consequently, the wiring area of ​​the NFC antenna 30 will decrease, thus compromising its radiation performance. Furthermore, Figure 1 In the scheme shown, the NFC antenna 30 is also a device on the stacking path of the electronic device in the thickness direction, that is, the thickness of the NFC antenna 30 is still the bottleneck for the overall thinning of the device.

[0043] As can be seen, in both of the above embodiments, the routing of the NFC antenna 30 is affected by the area occupied by the camera bracket 20. However, the current trend in electronic device development is that camera modules are becoming larger and the number of cameras is increasing. Therefore, the area occupied by the camera bracket 20 on the back cover 10 will also become larger. Clearly, Figure 4 and Figure 5 The arrangement of the NFC antenna 30 shown cannot meet the development requirements of electronic devices.

[0044] Furthermore, in both of the above embodiments, the NFC antenna 30 is a device on the stacking path of the electronic device in the thickness direction.

[0045] To address the bottleneck of thinning NFC antennas in existing technologies, and the problem that the wiring method of existing NFC antennas cannot guarantee the radiation performance of NFC antennas as the area occupied by camera brackets increases, this application provides an improved electronic device.

[0046] This electronic device can ensure the trace area of ​​the NFC antenna even in scenarios with large camera brackets, thereby guaranteeing the radiation performance of the NFC antenna and eliminating the NFC antenna as a bottleneck for thinning the electronic device. It should be understood that the electronic device in this application embodiment can be a mobile phone, tablet computer, desktop, laptop, handheld computer, notebook computer, ultra-mobile personal computer (UMPC), netbook, as well as cellular phones, personal digital assistants (PDAs), augmented reality (AR) / virtual reality (VR) devices, and other devices with NFC antennas and cameras. This application embodiment does not impose any special limitations on the specific form of the electronic device.

[0047] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0048] Please see Figure 6 and Figure 5 , Figure 6 The diagram shows the structure of an electronic device provided in some embodiments of this application. Figure 5 For along Figure 5 The cross-sectional view obtained by cutting along section line BB in the image. This electronic device is a mobile phone, including a mid-frame 50 (…). Figure 5 (not shown in the image), display screen 40 ( Figure 5 (Not shown in the image) and back cover 10. The middle frame 50 provides fixed support for the functional components within the electronic device and is typically made of metal materials such as stainless steel or aluminum alloy. The display screen 40 and back cover 10 are respectively disposed on opposite sides of the middle frame 50, and the display screen 40, middle frame 50, and back cover 10 are stacked. In some embodiments, the display screen 40 is provided with functional components such as a front-facing camera module, earpiece, and fill light. In some embodiments, a motherboard 60, battery, speaker, and other functional components are disposed between the back cover 10 and the middle frame 50. Furthermore, the back cover 10 has mounting holes for mounting the camera assembly of the electronic device.

[0049] like Figure 5 As shown, the camera assembly includes a camera bracket 20, and a camera, flash, or sensor mounted within the camera bracket 20. Figure 5 (Not shown). The sensor can be a laser ranging (time of flight, TOF) sensor, ambient light sensor, infrared temperature sensor, or other device that requires light for detection. The camera bracket 20, also known as a camera decorative piece, can be circular in shape. It should be understood that, although Figure 5The camera support 20 is illustrated as a circle, but the camera support 20 can also be an ellipse, a rectangle, a rhombus, or other regular or approximately regular shapes, and embodiments of the present application do not make specific limitations thereon. The camera support 20 is embedded in the mounting hole provided in the back cover 10, thereby being mounted on the back cover 10. The camera support 20 includes a first surface S1 and a second surface S2 (not shown) arranged oppositely Figure 5 The first surface S1 of the mounted camera support 20 is a side facing the outside of the electronic device.

[0050] The camera support 20 is provided with four first light transmission holes, namely a light transmission hole K1, a light transmission hole K2, a light transmission hole K3, and a light transmission hole K4. The light transmission hole K1 can be opposite to the camera for mounting the camera, in which case the light can pass through the light transmission hole K1 into the camera, thereby achieving shooting. The light transmission hole K1 can also be opposite to the flash for mounting the flash, in which case the light emitted by the flash can pass through the light transmission hole K1, thereby achieving illumination. The light transmission hole K1 can also be opposite to the sensor for mounting the sensor, in which case the sensor can monitor the external environment through the light transmission hole K1. It should be understood that “mounting” here means that the light transmission hole K1 needs to be arranged to have a direct opposite relationship with the camera, the flash, or the sensor, and does not mean that the camera, the flash, or the sensor has a direct connection relationship with the camera support 20. Of course, in other embodiments, there can be a direct connection relationship, and embodiments of the present application do not make specific limitations thereon. Subsequent related content is referred to this definition, and will not be described hereinafter. Other first light transmission holes can be implemented in the same way, and will not be described hereinafter. It should be understood that, in general, an electronic device only has one flash. Based on this, there is only one first light transmission hole in the electronic device for mounting the flash. It should be noted that, although Figure 6 The number of first light transmission holes is illustrated as four, and the four first light transmission holes are arranged in a square array, but this example should not be understood as a special limitation of the present application. In other embodiments, the number of first light transmission holes can be other numbers, such as 3, 4, 5, or even more. It should be understood that, as the number of cameras of the electronic device increases, the number of required first light transmission holes also increases. The more the number of first light transmission holes, the larger the size of the corresponding camera support 20, and the larger the area of the back cover occupied. In general, when the camera support 20 has more than three first light transmission holes, the area of the back cover occupied by the camera support 20 is large.

[0051] Furthermore, the light-transmitting holes K1, K2, K3, and K4 are arranged in a circular array along a square. Specifically, the circular array of light-transmitting holes K1, K2, K3, and K4 along a square refers to the array path where the circles (i.e., geometric centers) of light-transmitting holes K1, K2, K3, and K4 are connected end to end to form a square (shown by the dotted lines of the squares in the figure). It should be understood that the geometric center refers to the central position of an object with a certain degree of symmetry, such as the center of a circle, the center of a sphere, or the intersection of the two diagonals of a parallelogram. Based on this, in other embodiments, if the first light-transmitting hole is of other shapes, such as a rhombus, a square, or a rectangle, then the intersection of the two diagonals is the geometric center of the first light-transmitting hole. In addition, it should be noted that in other embodiments, other circular array paths can also be used, such as elliptical rings, rectangular rings, rhomboid rings, polygonal rings, etc., and this application does not specifically limit this.

[0052] like Figure 2 As shown, to implement NFC functionality, the electronic device also includes an NFC antenna 30. The NFC antenna 30 is disposed on the first surface S1 of the camera bracket 20, and the NFC antenna 30 is positioned along the thickness direction of the electronic device (i.e.,...). Figure 4 The orthographic projection (i.e., the first orthographic projection) of the first surface S1 (in the Z direction indicated by the middle arrow) falls within the first surface S1, meaning the NFC antenna 30 is laid within the first surface S1. Specifically, the NFC antenna 30 can be laid by creating a groove in the first surface S1 of the camera bracket 20. Since the camera bracket 20 protrudes significantly from the back cover 10, typically by 0.85~1.0mm or even higher, such as 2~3mm, it is evident that the thickness of the camera bracket 20 is sufficient, and its strength is adequate to support the NFC antenna 30 laid in the groove on its surface.

[0053] It should be noted that since the camera bracket 20 protrudes from the back cover 10 of the electronic device, it is not in the stacking path of the electronic device from the display screen 40 to the back cover 10, and its thickness is generally not considered a factor in reducing the thickness of the electronic device. Therefore, laying the NFC antenna 30 within the first surface S1 increases the thickness of the camera assembly protruding from the back cover 10, not the thickness of the electronic device. Compared to Figure 6 and Figure 5 In the illustrated scheme, the NFC antenna 30 is not in the stacking path from the display to the back cover 10, so the NFC antenna will not become a bottleneck for thinning the electronic device, and can also reduce the thickness of the electronic device. In addition, by laying the NFC antenna 30 on the first surface S1 of the camera bracket 20 through a groove, the NFC antenna 30 can also be flush with the first surface S1 of the camera bracket 20, thereby not increasing the thickness of the camera assembly protruding from the back cover 10.

[0054] It should also be noted that the embodiments of the present application only illustrate and describe the part of the NFC antenna 30 located inside the camera holder 20. It should be understood that the NFC antenna 30 also has a part located outside the camera holder 20, which is provided with a feeding point. The NFC antenna 30 is coupled with the radio frequency module on the mainboard 60 (not shown) through the feeding point. The radio frequency module receives electromagnetic waves via the NFC antenna 30, frequency-modulates and filters the electromagnetic wave signals, and sends the processed signals to the processor; the radio frequency module can also frequency-modulate, amplify and convert the signals sent by the processor into electromagnetic wave radiation via the NFC antenna 30. Figure 6 It is shown that, Figure 5 not shown) on the mainboard 60. The radio frequency module receives electromagnetic waves via the NFC antenna 30, frequency-modulates and filters the electromagnetic wave signals, and sends the processed signals to the processor; the radio frequency module can also frequency-modulate, amplify and convert the signals sent by the processor into electromagnetic wave radiation via the NFC antenna 30.

[0055] In addition, in the embodiments, since the NFC antenna 30 is moved from the stacking path in the thickness direction of the electronic device to the camera holder 20, the distance between the NFC antenna 30 and the mainboard 60 is further apart, and therefore the connection between the NFC antenna 30 and the mainboard 60 is different from the current connection scheme of the NFC antenna. Specifically, as shown in the figure, Figure 5 the NFC antenna 30 and the mainboard 60 can be connected by the spring sheet installed on the mainboard 60 abutting against the feeding point of the NFC antenna 30 on the camera holder 20. Compared with the ordinary spring sheet, the height of the spring sheet used in the embodiments is higher. In addition, a longer flexible printed circuit (FPC) can also be used. In this case, one end of the feeding point of the NFC antenna 30 can be fixed on the mainboard holder 70, and at this time, the ordinary spring sheet is used to abut against the mainboard holder 70. The FPC can also be replaced, and the connection mode of the NFC here can also be replaced with a board-to-board (B2B) connector.

[0056] As shown in the figure, Figure 5 In order to avoid the laying of the NFC antenna 30 affecting the normal work of the device corresponding to the first light hole, the first projection (i.e. the first projection) of the NFC antenna 30 and the light hole K1, the light hole K2, the light hole K3, the light hole K4 do not overlap, so that the NFC antenna avoids the light hole K1, the light hole K2, the light hole K3, the light hole K4. In this way, the NFC antenna 30 will not exist the case of shielding the first light hole.

[0057] In order to make the first projection and the light hole K1, the light hole K2, the light hole K3, the light hole K4 do not overlap, Figure 5In the electronic device shown, the NFC antenna 30 includes a toroidal ferrite 31, and a metal trace 32 that runs along the edge of the ferrite 31, the metal trace 32 also being toroidal, and the area of the metal trace 32 in the first orthographic projection being a trace projection area. Since the metal trace 32 is toroidal, the trace projection area is also toroidal. The through hole K1, the through hole K2, the through hole K3, and the through hole K4 are all located inside the toroidal inside of the trace projection area. In other words, the metal trace 32 surrounds the through hole K1, the through hole K2, the through hole K3, and the through hole K4 inside the metal trace 32.

[0058] In this embodiment, the metal trace 32 surrounds the through hole K1, the through hole K2, the through hole K3, and the through hole K4 inside the metal trace 32, and the ferrite 31 is not laid in the area inside the metal trace 32. Figure 5 As can be seen, the area inside the metal trace 32 is not laid with ferrite, that is, the through hole K1, the through hole K2, the through hole K3, and the through hole K4 also do not overlap the ferrite 31, and thus the first orthographic projection and the first through hole do not overlap, and thus the NFC antenna 30 can avoid the first through hole, and thus avoid affecting the normal operation of the device that the first through hole is directed at.

[0059] It should be understood that although Figure 6 The ferrite 31 is shown as a hollow toroidal structure. In other embodiments, the ferrite 31 can also be configured to only avoid the through hole K1, the through hole K2, the through hole K3, and the through hole K4, that is, on the inside of the first surface S1, the ferrite 31 is laid in the area inside the metal trace 32 (referred to as the area inside the metal trace 32). In this way, the risk of mutual interference between the NFC antenna 30 and other electronic components of the electronic device to form eddy currents can be further reduced, and the embodiments of the present application do not make specific limitations on this. It should be noted that the area of the ferrite 31 passed by the metal trace 32 is better than the area of the ferrite 31 not passed by the metal trace 32 (the area inside the metal trace 32) in terms of anti-interference effect. Since the radiation performance of the NFC antenna 30 is determined by the trace area of the metal trace 32, whether the area inside the metal trace 32 is laid with ferrite has a small effect on the improvement of the radiation performance of the NFC antenna 30, and considering the factors of cost and processing difficulty, the ferrite 31 is usually laid in the area of the metal trace 32. Figure 5 The ferrite 31 is laid in the area of the metal trace 32 as shown in the scheme.

[0060] In order to protect and beautify the camera, in some embodiments, as shown in Figure 5As shown, the electronic device further comprises a decorative lens 80, which is fixed on the first surface S1 by bonding with the adhesive area 90 at the edge of the first surface S1. The NFC antenna 30 is arranged between the decorative lens 80 and the first surface S1, and does not overlap the adhesive area 90. That is, the NFC antenna 30 needs to be laid away from the adhesive area 90 to avoid warping of the decorative lens 80 due to the NFC antenna 30 when the decorative lens 80 is installed, so as to avoid failure to achieve good bonding and sealing.

[0061] It should be noted that, Figure 5 The scheme shown is generally applicable to the scenario where the rear cover area occupied by the camera holder 20 is large, and the space between the first light hole and the edge of the camera holder 20 is large. In this way, it can be ensured that there is a large enough area between the first light hole and the camera holder 20 to lay the NFC antenna 30, so as to meet the radiation performance of the NFC antenna 30. In some embodiments, when the minimum distance between the edge line of the first light hole and the edge line of the camera holder 20 is greater than a first threshold, it can be determined that the space between the first light hole and the edge of the camera holder 20 is large.

[0062] Among them, the minimum distance between the edge line of the first light hole and the edge line of the camera holder 20 refers to the distance between the two positions closest to the edge line of the first light hole and the edge line of the camera holder 20. Next, taking the light hole K1 as an example, other first light holes can be implemented with reference. Please refer to Figure 7 When the camera holder 20 is circular and the light hole K1 is circular, a straight line is drawn from the center of the camera holder 20 to the center of the light hole K1, and the straight line intersects the edge line of the camera holder 20 and the edge line of the light hole K1 at points M and N, respectively. The distance between the points M and N is the minimum distance described above. In other embodiments, when the camera holder 20 is rectangular and the light hole K1 is circular, the minimum distance described above is the smallest distance among the distances from the center of the light hole K1 to the edges of the camera holder 20.

[0063] The first threshold described above is at least the width of the metal trace 32. The width of the metal trace 32 refers to the width occupied by all the coils (one coil of the metal trace 32 surrounds the ferrite 31 once, Figure 5 having two coils) on the ferrite 31, rather than the width of a single metal trace 32. For example, Figure 6As shown, the metal trace 32 encircling the ferrite 31 has three loops, and the trace width of the metal trace 32 is marked by the double arrowed line. In consideration of the fact that the metal trace 32 needs to be kept apart from the back adhesive area 90 and the first through-hole respectively, in order to avoid the back adhesive area 90 and the first through-hole, preferably, the first threshold value is greater than the trace width of the metal trace 32. For example, under the existing processing technology, the trace width of the metal trace 32 is usually 2.5 mm, the width of the back adhesive area 90 is usually 1 mm, the distance between the outer edge line of the back adhesive area 90 and the metal trace 32 is usually 0.5 mm, and the distance between the inner edge line of the metal trace 32 and the first through-hole is usually 1 mm, thus, the first threshold value can be twice the trace width of the metal trace 32.

[0064] It should be understood that, although Figure 5 It is illustrated that the ferrite 31 and the metal trace 32 are both circular rings, and the NFC antenna 30 as a whole also presents a circular ring. In other embodiments, the NFC antenna 30 can also be of other shapes, and the embodiments of the present application do not make specific limitations in this regard. It should be understood that, in order to achieve an aesthetic effect, the shape of the NFC antenna 30 can be designed differently according to the shape of the camera holder 20, the position of the first through-hole, the size of the window opened by the decorative lens 80, and other factors, to ensure the normal structural protection, the laying effect of the type identification information and parameter information of the camera assembly, and the like, and to maximize the hiding of the NFC antenna 30 under the CD decorative pattern of the decorative lens 80. Figure 8

[0065] Figure 8 As shown in the electronic device, the trace projection area is a ring, and the metal trace 32 is also a ring. Since the first through-hole is located inside the ring corresponding to the trace projection area, the metal trace 32 is laid between the first through-hole and the edge of the camera holder 20, and the first through-hole is surrounded by the metal trace 32. It can be seen that the metal trace 32 is a ring located between the first through-hole and the edge of the camera holder 20. With the increase in the number of cameras, the number of first through-holes increases, and the camera holder 20 also increases, thereby causing the area of the first surface S1 to increase accordingly. It should be understood that, when the area of the first surface S1 increases, the area of any ring located between the first through-hole and the edge of the camera holder 20 will also increase accordingly. Based on this, the trace area of the metal trace 32 (which is a ring located between the first through-hole and the edge of the camera holder 20) is improved, thereby improving the radiation performance of the NFC antenna 30.

[0066] Please refer to Figure 5 , Figure 5 The structural schematic diagram of an electronic device provided by some other embodiments of the present application is shown. Different from the above-mentioned embodiments Figure 5 ​The electronic device shown in the embodiment, the camera holder 20 is large in overall structure, and the space between the first light hole and the edge of the camera holder 20 is small. For example, when the minimum distance between the edge line of the first light hole and the edge line of the camera holder 20 is less than the second threshold value, it can be determined that the space between the first light hole and the edge of the camera holder 20 is small. The second threshold value is at least the width of the metal trace 32. The specific implementation of the minimum distance between the edge line of the first light hole and the edge line of the camera holder 20 can refer to the related content of Figure 5 , and the specific implementation of the second threshold value can also refer to the implementation of the first threshold value, which will not be described here. It should be understood that the first threshold value and the second threshold value can be the same value or different values, and the embodiments of the present application do not make specific limitations thereon. Obviously, in this case, the space between the first light hole and the edge of the camera holder 20 is not enough to implement the scheme shown in Figure 8 .

[0067] It should be understood that when the camera holder 20 is large in overall structure and the space between the first light hole and the edge of the camera holder 20 is small, the area within the array path of the first light hole (the closed path formed by sequentially connecting the geometric centers of the plurality of first light holes, and the dashed line of the square in the figure) is usually large. In this way, the area within the array path of the first light hole has a large enough area to lay the NFC antenna 30. Based on this, unlike the electronic device shown in Figure 8 , Figure 8 the electronic device shown in the embodiment, the light holes K1, K2, K3 and K4 are located on the annular outer side corresponding to the trace projection area and do not overlap with the first orthographic projection. In other words, Figure 5 in the scheme shown in the embodiment, the first light hole is located on the outer side of the metal trace 32, and the metal trace 32 is laid in the position within the array path of the first light hole.

[0068] It should be understood that since the metal trace 32 is laid along the edge of the ferrite 31, there is also a projection area of the ferrite 31 on the annular outer side corresponding to the trace projection area. In the embodiment, the light holes K1, K2, K3 and K4 are not only located on the annular outer side corresponding to the trace projection area, but also do not overlap with the first orthographic projection, so the first light hole in the embodiment is essentially laid on the outer side of the NFC antenna 30, not on the outer side of the metal trace 32. It should also be understood that in this embodiment, although Figure 8 the ferrite 31 is shown as a solid structure, in other embodiments, it can also be provided as a ring structure, and the specific implementation can refer to the related content of Figure 8 , which will not be described here.

[0069] Figure 8The electronic device shown, the wire projection area is annular, then the metal wire 32 is also annular. Since the first light transmission holes are all located outside the annular corresponding to the wire projection area, therefore, the metal wire 32 is laid in the position within the array path of the first light transmission hole. It can be seen that the metal wire 32 is annular within the array path of the first light transmission hole. With the increase of the number of cameras, the number of first light transmission holes increases, and the camera support 20 will also increase, thereby causing the area of the first surface S1 to increase accordingly. It should be understood that when the area of the first surface S1 increases, the area of any annular within the array path of the first light transmission hole will also increase accordingly. Based on this, the wire area of the metal wire 32 (annular within the array path of the first light transmission hole) is improved, thereby improving the radiation performance of the NFC antenna 30.

[0070] As shown in the figure, in order to obtain the largest possible wire area benefit to improve the radiation performance of the NFC antenna 30, the NFC antenna 30 has four extension regions, which are: extension region Q1, extension region Q2, extension region Q3, and extension region Q4. The following will take the extension region Q1 as an example to explain its specific implementation, and the other extension regions can be referred to for implementation. Figure 8

[0071] The extension region Q1 extends to the second direction (indicated by the dashed arrow in the figure) and passes through the position between the adjacent light transmission holes K1 (i.e. the first adjacent hole) and the light transmission hole K2 (i.e. the second adjacent hole) on the array path (indicated by the square dashed line in the figure). The second direction is away from the center of the first surface S1 (i.e. the geometric center of the first surface S1) and perpendicular to the array direction of the light transmission hole K1 and the light transmission hole K2. The array direction of the light transmission hole K1 and the light transmission hole K2 refers to the direction of the center line connecting the center (geometric center) of the light transmission hole K1 and the center (geometric center) of the light transmission hole K2. For convenience of description, the array direction of the light transmission hole K1 and the light transmission hole K2 will be referred to as the third direction hereinafter.

[0072] Among them, the extension region Q1 is also laid with the metal wire of the ferrite and the ferrite edge wire. The part of the metal wire 32 located in the extension region Q1 includes a first wire L1 and a second wire L2. The first wire L1 and the second wire L2 both extend to the second direction, pass through the position between the light transmission hole K1 and the light transmission hole K2, and the first wire L1 and the second wire L2 are arranged in the third direction.

[0073] ​In this embodiment, the presence of the extension region Q1 makes the NFC antenna 30 harvest the wiring area of the metal trace 32 in the extension region Q1, thus improving the radiation performance of the NFC antenna 30. In addition, the first trace L1 and the second trace L2 are both routed along the second direction, and can maintain the same spacing with the light passing hole K1 and the light passing hole K2, respectively. On the one hand, this can be more beautiful, and on the other hand, it can avoid the problem that one side has too large spacing and the other side has too small spacing and is not easy to process. In addition, the first trace L1 and the second trace L2 maintain a spacing in the third direction. Since the wiring area of the metal trace 32 is determined by the area surrounded by the metal trace 32, when the first trace L1 and the second trace L2 have a spacing in the third direction, the wiring area can be harvested by the extension region Q1, and the presence of the extension region Q1 is meaningful.

[0074] Of course, in other embodiments, the extension region Q1 can also deviate from the center of the first surface S1 and extend towards other positions between the light passing hole K1 and the light passing hole K2. Correspondingly, the first trace L1 and the second trace L2 also extend towards other positions between the light passing hole K1 and the light passing hole K2. It should be understood that, compared with the scheme of extending towards the second direction, the scheme of extending the extension region Q1 towards other positions (for example, towards the direction of the light passing hole K1) makes the spacing between the first trace L1 and the light passing hole K1 and the spacing between the second trace L2 and the light passing hole K2 inconsistent. On the one hand, this is not beautiful enough, and on the other hand, there is a problem that one side has too large spacing and the other side has too small spacing and is not easy to process.

[0075] In addition, the extension region Q1 can also not pass through the position between the light passing hole K1 and the light passing hole K2. Correspondingly, the first trace L1 and the second trace L2 also do not pass through the position between the light passing hole K1 and the light passing hole K2. It should be understood that since the most critical factor affecting the radiation performance of the NFC antenna 30 is the wiring area of the metal trace 32, the larger the wiring area of the metal trace 32, the better the radiation performance of the NFC antenna 30. Therefore, compared with the scheme in which the extension region Q1 does not pass through the position between the light passing hole K1 and the light passing hole K2, Figure 5 In the scheme shown, the extension region Q1 passes through the position between the light passing hole K1 and the light passing hole K2. In this way, the area of the extension region Q1 is large enough. The larger the area of the extension region Q1, the larger the wiring area of the metal trace 32, and the better the radiation performance of the NFC antenna 30. Since the metal trace 32 is routed around the edge of the ferrite 31, when the area of the ferrite of the extension region Q1 is larger, the wiring area of the metal trace 32 is also larger, and the radiation performance of the NFC antenna 30 is better.

[0076] It should be noted that the radiation performance of the NFC antenna 30 can be greatly improved by the extension area Q1 only when the line area of the metal trace 32 in the extension area Q1 is large enough, and the existence of the extension area Q1 is meaningful. In order to make the line area of the metal trace 32 in the extension area Q1 large enough, Figure 8 The scheme shown is generally applied to the scenario where the interval between the light-through hole K1 and the light-through hole K2 is large. Only in this way, a large interval can be kept between the first line L1 and the second line L2 to obtain a large line area.

[0077] In some embodiments, the interval between the light-through hole K1 and the light-through hole K2 in the array direction is greater than a third threshold value, and the third threshold value is at least three times the line width of the metal trace 32, which is regarded as a large interval between the light-through hole K1 and the light-through hole K2. Wherein, the interval between the light-through hole K1 and the light-through hole K2 in the array direction refers to the interval between the center of the light-through hole K1 and the center of the light-through hole K2. The specific definition of the line width of the metal trace 32 can be referred to Figure 9 The scheme shown is not repeated here. In this scenario, since the first line L1 and the second line L2 have occupied two line widths of the metal trace 32, there is still at least one line width of the metal trace 32 remaining between the first line L1 and the second line L2 without considering the interval for avoiding the light-through hole K1 and the light-through hole K2. Therefore, when the third threshold value is at least three times the line width of the metal trace 32, the interval between the light-through hole K1 and the light-through hole K2 is large enough, Figure 9 The scheme shown can obtain a large area benefit to the extension area Q1.

[0078] In the specific implementation process, considering that the extension area Q1 needs to keep an interval with the light-through hole K1 and the light-through hole K2 for avoidance, and when the interval between the first line L1 and the second line L2 is small, on the one hand, there is a problem of line difficulty, and on the other hand, there is a problem of low area benefit and less NFC performance improvement, the third threshold value can be greater than three times the line width of the metal trace 32. For example, under the existing processing process, the line width of the metal trace 32 is usually 2.5 mm, so the line width of the first line L1 and the second line L2 is 2.5 mm. The interval between the first line L1 and the second line L2 is 5 mm, the interval between the light-through hole K1 and the edge line of the extension area Q1 (the edge line close to the first line L1) is 1 mm, and the interval between the light-through hole K2 and the edge line of the extension area Q1 (the edge line close to the second line L2) is 1 mm, so the third threshold value can be four times the line width of the metal trace 32.

[0079] Please refer to Figure 8 , Figure 8A structural schematic diagram of an electronic device is provided for some other embodiments of the present application. Different from the electronic device shown in Figure 8 The electronic device shown in the figure, the interval of the light passing hole K1 and the light passing hole K2 in the array direction is not large. For example, when the interval of the light passing hole K1 and the light passing hole K2 in the array direction is less than the fourth threshold value, the fourth threshold value is at least three times the width of the metal trace 32, which can be considered as the interval of the light passing hole K1 and the light passing hole K2 in the array direction is not large. The specific implementation of the fourth threshold value can also refer to the implementation of the third threshold value. It should be understood that the fourth threshold value and the third threshold value can take the same value or different values, and the embodiments of the present application do not make specific limitations. In this case, if the scheme shown in Figure 9 The interval of the light passing hole K1 and the light passing hole K2 is too small, and the interval between the first trace L1 and the second trace L2 is also small, so the trace difficulty is large, and the requirement for the processing technology is extremely high. In addition, the interval between the first trace L1 and the second trace L2 is small, and the trace area benefit that can be obtained is small. It is undoubtedly a waste to harvest small trace area under difficult processing technology. Based on this, different from the electronic device shown in Figure 9 The electronic device shown in Figure 8 The electronic device shown in the figure, the interval of the light passing hole K1 and the light passing hole K2 in the array direction is not large. For example, when the interval of the light passing hole K1 and the light passing hole K2 in the array direction is less than the fourth threshold value, the fourth threshold value is at least three times the width of the metal trace 32, which can be considered as the interval of the light passing hole K1 and the light passing hole K2 in the array direction is not large. The specific implementation of the fourth threshold value can also refer to the implementation of the third threshold value. It should be understood that the fourth threshold value and the third threshold value can take the same value or different values, and the embodiments of the present application do not make specific limitations. In this case, if the scheme shown in

[0080] Specifically, the first trace L1 and the second trace L2 gradually approach in the second direction means that the interval between the two corresponding points on the first trace L1 and the second trace L1 gradually decreases in the second direction, wherein the two corresponding points on the first trace L1 and the second trace L1 are two points intersected by a straight line extending in the third direction (perpendicular to the second direction) and the first trace L1 and the second trace L1, respectively.

[0081] In this scheme, if the first trace L1 and the second trace L2 are in the gradually approaching state in the second direction, then when passing through the position between the light passing hole K1 and the light passing hole K2, the interval between the first trace L1 and the light passing hole K1 and the interval between the second trace L2 and the light passing hole K2 are both large, and there will be no difficulty in the trace due to the small interval of the light passing hole K1 and the light passing hole K2 in the array direction. In addition, compared with the scheme without the extension area Q1, Figure 10 The scheme shown in the figure can harvest the trace area of the metal trace 32 in the extension area Q1, thereby improving the radiation performance of the NFC antenna.

[0082] It should be understood that in other embodiments, the extension region Q1 may not pass through the space between the light-transmitting holes K1 and K2, and the extension region Q1 may extend to other locations between the light-transmitting holes K1 and K2. The first trace L1 and the second trace L2 may also converge in other directions between the light-transmitting holes K1 and K2. This application does not specifically limit this aspect; for specific implementation effects, please refer to [the relevant documentation]. Figure 10 The proposed solution will not be elaborated upon here.

[0083] It should be noted that the most critical factor affecting the radiation performance of the NFC antenna 30 is the trace area of ​​the metal trace 32. The presence or absence of ferrite within the trace area of ​​the metal trace 32 has a relatively small impact on the radiation performance of the NFC antenna 30. Based on this, the embodiments of this application also provide the following... Figure 10 The electronic device shown.

[0084] Please see Figure 9 , Figure 10 This is a schematic diagram of the structure of an electronic device provided in other embodiments of this application. Distinguished from... Figure 9 The illustrated electronic device includes an NFC antenna 30 with a clearance hole 33 (located at the same position as the light-transmitting hole K5). The clearance hole K5 is positioned in the area projected onto the first orthographic projection as a clearance area, located on the inner side of the annular area corresponding to the trace projection area. This clearance area overlaps with the light-transmitting hole K5 (i.e., the second light-transmitting hole). In other words, the light-transmitting hole K5 is located in the area of ​​the camera bracket 20 directly opposite the clearance hole 33. The light-transmitting hole K5 can be positioned opposite the camera, allowing light to pass through the clearance hole 33 and then the light-transmitting hole K5 to enter the camera for image capture; it can also be positioned opposite the flash, allowing light emitted from the flash to pass through the light-transmitting hole K5 and then the clearance hole 33 to illuminate the outside of the electronic device; or it can be positioned opposite the sensor, allowing the sensor to monitor the external environment through the clearance hole 33 and the light-transmitting hole K5.

[0085] It should be understood that the avoidance area is located on the inner side of the annulus corresponding to the trace projection area, meaning that the avoidance hole 33 is located within the metal trace 32. The presence of the avoidance hole 33 does not affect the trace area of ​​the metal trace 32, and therefore does not affect the radiation performance of the NFC antenna 30. While ensuring the radiation performance of the NFC antenna 30, Figure 8 The proposed solution is compared to Figure 5 The solution shown in this embodiment adds a light-transmitting hole without increasing the size of the camera bracket, thus supporting the installation of an additional camera, which is beneficial to meet the trend of increasing camera numbers.

[0086] It should also be understood that Figure 8In the solution shown, a clearance hole 33 can also be provided on the NFC antenna 30 to increase the number of cameras.

[0087] It should be noted that the first light-passing hole can be used to mount a camera, flash, or sensor. Therefore, different first light-passing holes can mount different devices, and their sizes may vary. Generally speaking, when mounting a flash, a small sensor, or a small camera, the first light-passing hole is smaller; when mounting a larger camera or sensor, the first light-passing hole is larger. Based on this, in practical applications, there may be scenarios where the space between some first light-passing holes and the edge of the camera bracket 20 is small, and other scenarios where the space between some first light-passing holes and the edge of the camera bracket 20 is large, not as... Figure 9 , Figure 10 , Figure 7 ,as well as Figure 11 Similarly, either all the first light-transmitting holes have a large space between them and the edge of the camera bracket 20, or all the first light-transmitting holes have a small space between them and the edge of the camera bracket 20.

[0088] In some embodiments, when the minimum distance between the edge line of the first light-transmitting hole and the edge line of the camera bracket 20 is less than a first threshold, it can be considered that the space between the first light-transmitting hole and the edge of the camera bracket 20 is small; when the minimum distance between the edge line of the first light-transmitting hole and the edge line of the camera bracket 20 is greater than the first threshold, it can be considered that the space between the first light-transmitting hole and the edge of the camera bracket 20 is large. The specific implementation of the first threshold can be found in [reference needed]. Figure 11 The description of the first threshold will not be repeated here. For an example, please refer to [link to relevant documentation]. Figure 9 , Figure 9 This is a schematic diagram of the structure of an electronic device provided in other embodiments of this application. In this electronic device, the minimum distance between the edge lines of light-transmitting holes K1, K2, and K4 and the edge line of the camera bracket 20 is respectively... Figure 9 Consistent, all less than the first threshold. Distinguished from... Figure 11 The electronic device shown has a minimum spacing between the edge line of the light-transmitting hole K3 and the edge line of the camera bracket 20 that is greater than a first threshold. Therefore, the space between the light-transmitting hole K3 and the edge of the camera bracket 20 is large, which can support the laying of NFC antennas to obtain a larger wiring area.

[0089] Based on this, it is different from Figure 11 The proposed scheme Figure 11In the electronic device shown, the light passing hole K3 is located inside the ring-shaped area corresponding to the wire projection area. In other words, the metal wire 32 surrounds the light passing hole K3 inside. As can be seen, in this embodiment, the position on the camera holder 20 where the wire can pass (the position between the light passing hole K3 and the edge of the camera holder 20) is fully utilized, the wire area is maximized, and the radiation performance of the NFC antenna 30 is improved.

[0090] It should be understood that when the light passing hole K3 is surrounded inside by the metal wire 32, a clearance hole 34 needs to be formed on the NFC antenna 30, and the clearance hole 34 is directly opposite the light passing hole K3. In addition, Figure 10 Although it is shown that only the light passing hole K3 has a large spacing between the camera holder 20 edge among the four first light passing holes. In other embodiments, there can be more first light passing holes with a large spacing between the camera holder 20 edge, and the implementation process is similar to that of the light passing hole K3, which will not be described here.

[0091] It should also be understood that ​ The electronic device shown can also refer to ​ In the scheme shown, the clearance hole 33 is formed on the NFC antenna 30 to increase the number of cameras, and the present embodiment does not make specific limitations on this.
