[0025] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0026] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0027] In order to better understand the technical solutions provided by the embodiments of the present application, the relevant principles and concepts that may be involved in the embodiments of the present application are explained below.

[0028] In electronic devices, the middle frame of the electronic device can usually form an antenna, and the annular decorative structure (also called a "loop" structure) in the electronic device can become a structure close to the antenna. The annular decorative structure close to the antenna can act as a parasitic structure of the antenna, which is prone to generate loop mode interference, thereby affecting the antenna performance of the electronic device.

[0029] For example, please refer to Figure 1, which is a structural diagram of a camera decoration in an electronic device in the related art. The camera decoration includes a metal "loop" structure 100. Since the metal "loop" structure 100 is close to the antenna middle frame, the antenna formed by the antenna middle frame includes WiFi 2.4G and WiFi 5G. The antenna is a 1 / 4 inverted-F antenna (IFA) in the 2.4G WiFi working mode. The metal "loop" structure 100 acts as a parasitic structure at this time, and its physical circumference is 108mm. The wavelength generated by the loop mode in Figure 1 is about 54mm. According to f=c / λ, λ is the equivalent medium wavelength. At this time, it is close to about 50mm at 2.3GHz. The coupled capacitance loading factor causes a loop resonance mode to be generated at 2.3GHz, that is, loop mode clutter will be generated, thereby affecting the antenna performance.

[0030] The decorative structure, functional device and electronic device provided in the embodiments of the present application are described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0031] The embodiment of the present application provides a decorative structure, which is applied to a functional device of an electronic device, for example, a camera decorative part, a fill light decorative part, etc. The decorative structure is close to the antenna of the electronic device.

[0032] Referring to Figures 2 to 4 , the decorative structure provided in the embodiment of the present application includes an annular metal ring 11 and a conductive member 12. The annular metal ring 11 includes a first side 111 and a second side 112 that are opposite to each other. The conductive member 12 includes a first end and a second end that are opposite to each other. The first end is connected to a first portion of the first side 111 via a first insulating member 123, and the second end is connected to a second portion of the second side 112 via a second insulating member 124. The first portion is located near or at the midpoint of the first side 111, and the second portion is located near or at the midpoint of the second side 112.

[0033] It can be understood that the decorative structure is close to the antenna of the electronic device, and the annular metal ring 11 in the decorative structure may generate a loop resonance mode, that is, form a circular current mode as shown in Figure 1, wherein the midpoint of the first side 111 and the midpoint of the second side 112 of the annular metal ring 11 are current zero points (current zero points as shown in Figure 1).

[0034] In the embodiment of the present application, a conductive member 12 is connected to the annular metal ring 11, and one end of the conductive member 12 is connected to the midpoint of the first side 111 or a portion close to the midpoint, and the other end is connected to the midpoint of the second side 112 or a portion close to the midpoint. As shown in FIG1 , the conductive member 12 is an "I"-shaped conductive member 12. In this way, the two ends of the conductive member 12 are respectively connected to the current zero point or a portion close to the current zero point in the circular current mode that the annular metal ring 11 may originally generate. In this way, the conductive member 12 can destroy the circular current mode that the annular metal ring 11 may originally generate, thereby reducing the energy coupled to the annular metal ring 11 and removing the loop mode interference outside the target frequency band (such as 2.4 GHz), thereby effectively improving the antenna performance of the electronic device.

[0035] It should be noted that the ring shape described in the embodiments of the present application includes but is not limited to closed structural shapes such as circular, elliptical, circular, and square shapes with a through hole in the middle.

[0036] Further, referring to Figures 3 and 4, the annular metal ring 11 also includes a third side 113 connecting the first side 111 and the second side 112; the conductive member 12 includes a first connecting member 121 and a second connecting member 122, the first connecting member 121 includes the first end and the second end, the second connecting member 122 includes a relative third end and a fourth end, the third end is connected to the first connecting member 121, and the fourth end is connected to the third side 113 through a third insulating member 125.

[0037] Referring to Figure 3 , the annular metal ring 11 includes a first side 111, a third side 113, a second side 112, and a fourth side 114, connected end to end. The first side 111 faces the second side 112, and the third side 113 faces the fourth side 114. The conductive member 12 includes a first connector 121 and a second connector 122. The first connector 121 has two ends connected to the first side 111 and the second side 112, respectively. The second connector 122 has two ends connected to the first connector 121 and the third side 113, respectively. This ensures that the conductive member 12 is connected to each of the three sides of the annular metal ring 11, further helping to disrupt the loop current pattern that the annular metal ring 11 might otherwise generate, removing the loop mode interference outside the target frequency band, thereby preventing it from affecting the antenna performance of the electronic device and effectively improving the antenna performance of the electronic device.

[0038] Optionally, the second connector 122 is perpendicular to the first connector 121, and the fourth end is close to or located at the midpoint of the third side 113. As shown in Figures 3 and 4, the conductive member 12 is a T-shaped conductive member 12; compared to the "I"-shaped conductive member 12, the T-shaped conductive member 12 can be connected to the midpoints of the three sides of the annular metal ring 11. Therefore, the T-shaped conductive member 12 can disrupt the loop current pattern originally generated by the annular metal ring 11, thereby reducing the energy coupled to the annular metal ring 11, thereby removing the loop mode interference outside the target frequency band and improving the antenna performance of the electronic device.

[0039] For a better understanding, the decorative structure in the camera decoration of an electronic device is used as an example for explanation. Referring to FIG5 , a T-shaped conductive member 12 is provided in the annular decorative structure in the camera decoration. The passive efficiency test of the annular decorative structure in the camera decoration is performed, and the results are shown in FIG6 . In the absence of the annular decorative structure, the passive efficiency is flat, and the passive efficiency corresponding to the measured efficiency WiFi 2.4G is -6.7; when there is an annular decorative structure (that is, the presence of a circular current mode) (such as the camera decoration provided in FIG1 ), the clutter falls at the position marked 1 in the figure, causing an efficiency pit, which is 2.3 GHz, just falling within the WiFi 2.4G band, and the passive efficiency is -8.6 dB; when the decorative structure is loaded with the T-shaped conductive member 12 (that is, the decorative structure provided in this application), the clutter shifts to 2.72 GHz, the pit shifts by 420 MHz, and the clutter is removed outside the target frequency band. At this time, the passive efficiency is -7.4 dB, and does not affect WiFi 5G. Therefore, after loading the T-shaped conductive member 12, the passive efficiency performance of WiFi 2.4G is improved by 1.2dB, which has a significant effect and can effectively improve the antenna performance of electronic devices.

[0040] Optionally, in an embodiment of the present application, the conductive part 12 is ductile, thereby making the conductive part 12 have stronger cushioning and anti-reliability, avoiding the conductive part 12 from breaking when the electronic device declines or encounters hard force damage, and helping to improve the service life of the conductive part 12.

[0041] Optionally, the conductive member 12 is a conductive cloth. As will be appreciated, the conductive cloth has good ductility, thereby ensuring that the conductive member 12 has good cushioning and reliability. Alternatively, the conductive member 12 may be a conductive metal with good ductility, thereby ensuring the conductive member's cushioning and reliability.

[0042] In the embodiment of the present application, the conductive member 12 can be connected to the side of the annular metal ring 11 by bonding, welding, screw connection, or other connection methods. For example, the first insulating member 123, the second insulating member 124, and the third insulating member 125 are all made of insulating adhesive, such as a pressure-sensitive adhesive, which can effectively ensure the stability of the connection between the conductive member 12 and the annular metal ring 11 while ensuring insulation. Alternatively, the first insulating member 123, the second insulating member 124, and the third insulating member 125 can be made of other insulating materials, which are not specifically limited in the embodiment of the present application.

[0043] Optionally, the conductive member 12 includes a conductive member body and an insulating connector, the insulating connector includes the first insulating member 123, the second insulating member 124 and the third insulating member 125, the insulating connector is attached to one side of the conductive member body, and the outer dimensions of the insulating connector are greater than or equal to the outer dimensions of the conductive member body. For example, the insulating connector is a pressure-sensitive adhesive attached to one side of the conductive body, so as to ensure that the conductive body can be connected to the annular metal ring 11 and other devices in the electronic device through the pressure-sensitive adhesive; the above-mentioned first insulating member 123, second insulating member 124 and third insulating member 125 are also part of the pressure-sensitive adhesive. For example, when the conductive body is T-shaped, the first insulating member 123, second insulating member 124 and third insulating member 125 are respectively attached to the three ends of the T-shaped conductive body, so that the pressure-sensitive adhesive covers one side of the conductive body and its end, and the outer dimensions of the pressure-sensitive adhesive are also larger than the outer dimensions of the conductive body, so as to realize the connection between the conductive body and the annular metal ring 11 and other devices in the electronic device, thereby ensuring the connection stability of the conductive body.

[0044] Optionally, the decorative structure further includes a lampshade 30 , the conductive member 12 is disposed on one side of the lampshade 30 , and the lampshade 30 is accommodated in the annular metal ring 11 .

[0045] For example, referring to FIG7 , the decorative structure is a camera decorative member, which is disposed on the outer surface of the back cover 40 of the electronic device. The camera decorative member includes a camera decorative ring 20 and a lampshade 30 . The camera decorative ring 20 includes the annular metal ring 11 . The conductive member 12 is disposed on one side of the lampshade 30 . The lampshade 30 is accommodated within the annular metal ring 11 .

[0046] It is understandable that the camera decorative part is usually set on the back cover 40 of the electronic device to decorate the camera that may protrude from the back cover 40 in the electronic device, so as to ensure the aesthetics of the entire electronic device. In the embodiment of the present application, the camera decorative part includes a camera decorative ring 20 and a lampshade 30. The lampshade 30 may refer to the lampshade 30 of the fill light arranged adjacent to the camera, which is used to decorate the fill light. Optionally, as shown in Figure 7, the camera decorative ring 20 includes an annular metal ring 11. The shape and size of the annular metal ring 11 are adapted to the shape and size of the lampshade 30, so that the annular metal ring 11 can be used to accommodate the lampshade 30. The conductive member 12 is set on one side of the lampshade 30. When the lampshade 30 is accommodated in the annular metal ring 11, the conductive member 12 on the lampshade 30 is connected to the annular metal ring 11. The connection method of the conductive member 12 and the annular metal ring 11 is as described in the previous embodiment and will not be repeated here.

[0047] In the embodiment of the present application, a conductive member 12 is provided on one side of the lampshade 30, so that when the lampshade 30 is accommodated in the annular metal ring 11 of the camera decorative ring 20, the conductive member 12 on the lampshade 30 can be connected to the annular metal ring 11, thereby destroying the circular current mode originally generated by the annular metal ring 11 in the camera decorative member, reducing the energy coupled to the annular metal ring 11, thereby removing the loop mode interference outside the target frequency band, avoiding the influence of the camera decorative member on the antenna performance, and effectively improving the antenna performance of the electronic device.

[0048] Optionally, the lampshade 30 may be fixed to the annular metal ring 11 by bonding, clamping, screw connection, etc., which is not specifically limited in the embodiment of the present application.

[0049] Alternatively, referring to FIG8 , the lampshade 30 includes a lampshade body 31, a first reflective film 32, and a second reflective film 33. The first reflective film 32 and the second reflective film 33 are respectively disposed on opposite sides of the lampshade body 31, with the first reflective film 32 being closer to the back cover 40 of the electronic device than the second reflective film 33. The conductive member 12 is disposed on the side of the first reflective film 32 facing away from the second reflective film 33. In this manner, the conductive member 12 is disposed outside the lampshade 30, that is, exposed on the outer surface of the lampshade 30. This ensures that the conductive member 12 can connect to the annular metal ring 11 when the lampshade 30 is accommodated within the annular metal ring 11, thereby avoiding any connection obstruction caused by the conductive member 12 being disposed inside the lampshade 30. In addition, the conductive member 12 is arranged on the side of the first reflective film 32 facing away from the second reflective film 33, and the first reflective film 32 is closer to the back cover 40 of the electronic device, that is, the conductive member 12 is arranged between the first reflective film 32 and the back cover 40 of the electronic device. As mentioned above, the conductive member 12 has a certain ductility. Such an arrangement can protect the conductive member 12 through the first reflective film 32, the lampshade body 31 and the second reflective film 33, thereby preventing the conductive member 12 from being broken or damaged due to being too close to the outside of the electronic device.

[0050] It should be noted that the first reflective film 32 and the second reflective film 33 can be respectively attached to both sides of the lampshade body 31 by bonding, so as to assemble the lampshade 30 .

[0051] Optionally, please further refer to Figure 9. The first reflective film 32 includes a first reflective film body 321, a first adhesive layer 322, and an annular decorative film 323. The first adhesive layer 322 is formed with a hollow portion 320 for accommodating the conductive member 12, and the shape of the hollow portion 320 is consistent with the shape of the conductive member 12. Exemplarily, the conductive member 12 is a T-shaped conductive member 12, and the hollow portion 320 is also T-shaped, thereby forming a space for accommodating the conductive member 12. The first adhesive layer 322 is coated on one side of the first reflective film body 321, and the annular decorative film 323 is connected to the first reflective film body 321 through the first adhesive layer 322. The conductive member 12 can also be connected to the first reflective film body 321 by bonding. The first reflective film body 321 is connected to the back cover 40 through the coated first adhesive layer 322, thereby ensuring the connection stability of the conductive member 12.

[0052] The present application also provides an electronic device including the above-described decorative structure, which is disposed on a rear cover of the electronic device. It should be noted that the electronic device provided in the present application includes all the technical features of the above-described decorative structure and can achieve the same technical effects. To avoid repetition, these features will not be described here.

[0053] Alternatively, referring to Figure 10 , assuming the decorative structure is a camera decorative member, the camera decorative ring 20 of the camera decorative member further includes at least one grounding portion 21, which is connected to the electronic device's mainboard. As shown in Figure 10 , the camera decorative ring 20 includes three grounding portions 21, each of which is connected to a spring clip on the mainboard, thereby enabling mainboard reflow and further improving the performance of the electronic device's antenna.

[0054] Referring to FIG. 11 , in the embodiment of the present application, the lampshade 30 and the camera decorative ring 20 can be assembled in the following manner:

[0055] ①: Assemble the camera decorative ring 20; ②: Assemble the lampshade 30 into the annular metal ring of the camera decorative ring 20 by snap-fitting. As previously mentioned, the conductive member 12 is disposed on one side of the lampshade 30. After the lampshade 30 is assembled into the annular metal ring of the camera decorative ring 20, the conductive member 12 is also connected to the annular metal ring 11. The inner wall of the annular metal ring may be provided with a slot 22, into which the end of the conductive member 12 and the insulating members disposed thereon (such as the first insulating member 123, the second insulating member 124, and the third insulating member 125) can be snapped, thereby connecting the conductive member 12 to the annular metal ring of the camera decorative ring 20, thereby obtaining the structure shown in ③. ④: The camera decorative ring 20, with the lampshade 30 assembled thereon, is affixed to the back cover 40 of the electronic device using the second adhesive 50 shown in FIG. The camera decorative member is then secured to the back cover 40 of the electronic device with screws, thereby ensuring a secure installation of the camera decorative member to the back cover 40.

[0056] Please further refer to Figure 7. After the lampshade 30 and the camera decorative ring 20 are fixed to the back cover 40 by the second adhesive 50, the bracket 60 is pasted together with the back cover 40 and the camera decorative ring 20, and can be further fixed by screws; a protective cover 70 can also be provided on the side of the camera decorative ring 20 facing away from the back cover 40 to protect the lampshade 30 installed in the annular metal ring.
