Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, specifically relating to a decorative structure and an electronic device. Background Technology

[0002] With the development of electronic technology, mobile phones, tablets, computers, and other electronic devices have become indispensable in people's daily lives. Taking mobile phones as an example, most mobile phones have circular decorative structures, such as the circular decorative ring in the camera module or other circular decorative structures. When these circular decorative structures are close to the antenna, they are prone to generating loop-mode clutter, which can affect the antenna performance of electronic devices. Summary of the Invention

[0003] The purpose of this application is to provide a decorative structure and an electronic device that can solve the problem that decorative structures in current electronic devices are prone to generating loop-mode clutter, which affects the antenna performance of the electronic device.

[0004] In a first aspect, embodiments of this application provide a decorative structure applied to an electronic device, the decorative structure being located near the antenna of the electronic device, the decorative structure comprising:

[0005] An annular metal ring, the annular metal ring including opposing first and second sides;

[0006] A conductive component, comprising a first end and a second end opposite to each other, wherein the first end is connected to a first portion of the first side via a first insulating component, and the second end is connected to a second portion of the second side via a second insulating component;

[0007] The first part is the part that is close to or located at the midpoint of the first side, and the second part is the part that is close to or located at the midpoint of the second side.

[0008] Secondly, embodiments of this application provide an electronic device including the decorative structure described in the first aspect, the decorative structure being disposed on the outer surface of the rear cover of the electronic device.

[0009] The decorative structure provided in this application embodiment includes an annular metal ring and a conductive element. The conductive element is connected to the annular metal ring, and one end of the conductive element is connected to the midpoint or near the midpoint of the first side of the annular metal ring, while the other end is connected to the midpoint or near the midpoint of the second side of the annular metal ring. In this way, the two ends of the conductive element are respectively connected to the zero point or near the current zero point in the annular current mode that the annular metal ring might generate.

[0023] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0024] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] To better understand the technical solutions provided in the embodiments of this application, the relevant principles and concepts that may be involved in the embodiments of this application are explained below.

[0026] In electronic devices, the frame can often form an antenna. Consequently, the ring-shaped decorative structure (also known as the "loop" structure) in the electronic device can become a structure close to the antenna. The ring-shaped decorative structure close to the antenna can act as a parasitic structure of the antenna, which can easily generate loop mode clutter, thereby affecting the antenna performance of the electronic device.

[0027] For example, please refer to Figure 1 , Figure 1 This is a structural diagram of a camera decorative component in an existing electronic device. The camera decorative component includes a metal "U"-shaped structure 100. Since this metal "U"-shaped structure 100 is located near the antenna frame, the antenna frame forms an antenna that includes both WiFi 2.4G and WiFi 5G. In the 2.4G WiFi operating mode, the antenna is a 1 / 4 inverted-F antenna (IFA). The metal "U"-shaped structure 100 then acts as a parasitic structure, with a physical perimeter of 108 mm. Figure 1The loop mode generates a wavelength of approximately 54 mm. According to f = c / λ, where λ is the equivalent dielectric wavelength, this is approximately 50 mm at 2.3 GHz. With the added coupling capacitance, a loop resonant mode is generated at 2.3 GHz, which also produces loop mode clutter, thus affecting the antenna performance.

[0028] The decorative structure, functional device, and electronic device provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0029] This application provides a decorative structure applied to functional components of an electronic device, such as camera trim, fill light trim, etc. The decorative structure is positioned close to the antenna of the electronic device.

[0030] Please refer to Figures 2 to 4 The decorative structure provided in this application embodiment includes an annular metal ring 11 and a conductive element 12. The annular metal ring 11 includes opposing first side 111 and second side 112. The conductive element 12 includes opposing first end and second end. The first end is connected to a first portion of the first side 111 via a first insulating element 123, and the second end is connected to a second portion of the second side 112 via a second insulating element 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.

[0031] Understandably, the decorative structure is located near the antenna of the electronic device, and the annular metal ring 11 in the decorative structure may generate a loop resonant mode, that is, form a loop resonant mode. Figure 1 The ring current pattern shown has a zero current point at the midpoint of the first side 111 and the midpoint of the second side 112 of the ring metal ring 11 (e.g., Figure 1 (The current zero point is shown).

[0032] In this embodiment, a conductive element 12 is connected to the annular metal ring 11. One end of the conductive element 12 is connected to the midpoint or near the midpoint of the first side 111, and the other end is connected to the midpoint or near the midpoint of the second side 112. Figure 1As shown, the conductive element 12 is a "I"-shaped conductive element 12. In this way, the two ends of the conductive element 12 are respectively connected to the current zero point or the part near the current zero point in the loop current mode that the ring metal ring 11 may generate. In this way, the conductive element 12 can disrupt the loop current mode that the ring metal ring 11 may generate, thereby reducing the energy coupled to the ring metal ring 11 and removing loop mode clutter outside the target frequency band (such as 2.4GHz), thereby effectively improving the antenna performance of the electronic device.

[0033] It should be noted that the annular shape described in the embodiments of this application includes, but is not limited to, closed structural shapes such as circles, ellipses, loops, and squares with a through hole in the middle.

[0034] Further, please refer to Figure 3 and 4 The annular metal ring 11 further includes a third side 113 connecting the first side 111 and the second side 112; the conductive element 12 includes a first connector 121 and a second connector 122, the first connector 121 includes a first end and a second end, the second connector 122 includes a third end and a fourth end opposite to each other, the third end is connected to the first connector 121, and the fourth end is connected to the third side 113 through a third insulating element 125.

[0035] Please refer 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, with the first side 111 opposite to the second side 112, and the third side 113 opposite to the fourth side 114. The conductive element 12 includes a first connector 121 and a second connector 122, with the two ends of the first connector 121 connected to the first side 111 and the second side 112 respectively, and the two ends of the second connector 122 connected to the first connector 121 and the third side 113 respectively. This allows the conductive element 12 to be connected to the three sides of the annular metal ring 11, which helps to disrupt the loop current pattern that the annular metal ring 11 might otherwise generate, removing loop clutter outside the target frequency band, avoiding impact on the antenna performance of the electronic device, and effectively improving the antenna performance of the electronic device.

[0036] 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. For example... Figure 3 and 4As shown, the conductive element 12 is a T-shaped conductive element 12. Compared with the straight conductive element 12, the T-shaped conductive element 12 can be connected to the midpoint of the three sides of the ring metal ring 11 respectively. In this way, the T-shaped conductive element 12 can disrupt the original ring current mode generated by the ring metal ring 11, reduce the energy coupled to the ring metal ring 11, and remove loop mode clutter outside the target frequency band, thereby improving the antenna performance of the electronic device.

[0037] To better understand, let's take the decorative structure in the camera lens of an electronic device as an example. Please refer to... Figure 5 The ring-shaped decorative structure in the camera decorative component contains a T-shaped conductive element 12. A passive efficiency test was performed on the ring-shaped decorative structure in the camera decorative component, and the results are as follows: Figure 6 As shown, without the ring-shaped decorative structure, the passive efficiency is flat, with a measured passive efficiency of -6.7 for WiFi 2.4G; however, when the ring-shaped decorative structure is present (i.e., the ring current mode exists), as shown in the figure... Figure 1 The provided camera decorative element causes clutter to fall at position 1 in the diagram, resulting in an efficiency dip. This point is at 2.3GHz, which falls within the WiFi 2.4G band, at which point the passive efficiency is -8.6dB. When the decorative structure is fitted with the T-shaped conductive element 12 (i.e., the decorative structure provided in this application), the clutter shifts to 2.72GHz, the dip shifts by 420MHz, and the clutter is removed from the target frequency band. At this point, the passive efficiency is -7.4dB, and it does not affect WiFi 5G. Therefore, after loading the T-shaped conductive element 12, the WiFi 2.4G passive efficiency performance is improved by 1.2dB, which is significant and can effectively improve the antenna performance of electronic devices.

[0038] Optionally, in this embodiment, the conductive element 12 has ductility, which in turn makes the conductive element 12 have stronger buffering and reliability, avoiding the breakage of the conductive element 12 caused by the electronic device fading or encountering hard damage, and helping to improve the service life of the conductive element 12.

[0039] Optionally, the conductive element 12 is a conductive cloth. Understandably, the conductive cloth has good ductility, thereby ensuring that the conductive element 12 has good cushioning and reliability. Alternatively, the conductive element 12 can also be a conductive metal with good ductility, thereby ensuring the cushioning and reliability of the conductive element.

[0040] In this embodiment, the conductive element 12 can be connected to the side of the annular metal ring 11 by means of bonding, welding, screw connection, etc. For example, the first insulating element 123, the second insulating element 124, and the third insulating element 125 are all insulating adhesives, such as pressure-sensitive adhesives, which can effectively ensure the connection stability between the conductive element 12 and the annular metal ring 11 while ensuring the insulation effect. Alternatively, the first insulating element 123, the second insulating element 124, and the third insulating element 125 can also be other insulating materials, which are not specifically limited in this embodiment.

[0041] Optionally, the conductive element 12 includes a conductive element body and an insulating connector. The insulating connector includes a first insulating element 123, a second insulating element 124 and a third insulating element 125. The insulating connector is attached to one side of the conductive element body, and the external dimensions of the insulating connector are greater than or equal to the external dimensions of the conductive element body. For example, the insulating connector is a pressure-sensitive adhesive applied to one side of the conductive component body, thereby ensuring that the conductive component body can be connected to the annular metal ring 11 and other devices in the electronic device through the pressure-sensitive adhesive; the first insulating component 123, the second insulating component 124, and the third insulating component 125 are also part of the pressure-sensitive adhesive. For example, when the conductive component body is T-shaped, the first insulating component 123, the second insulating component 124, and the third insulating component 125 are respectively applied to the three ends of the T-shaped conductive component body, thereby making the pressure-sensitive adhesive cover one side and its ends of the conductive component body. The external dimensions of the pressure-sensitive adhesive are also larger than the external dimensions of the conductive component body, thereby realizing the connection between the conductive component body and the annular metal ring 11 and other devices in the electronic device, ensuring the connection stability of the conductive component body.

[0042] Optionally, the decorative structure further includes a lampshade 30, with the conductive element 12 disposed on one side of the lampshade 30, and the lampshade 30 housed within the annular metal ring 11.

[0043] For example, please refer to Figure 7 The decorative structure is a camera decorative component, which is disposed on the outer surface of the back cover 40 of the electronic device. The camera decorative component includes a camera decorative ring 20 and a lampshade 30. The camera decorative ring 20 includes the annular metal ring 11, and the conductive element 12 is disposed on one side of the lampshade 30, which is housed within the annular metal ring 11.

[0044] Understandably, camera decorative elements are typically mounted on the back cover 40 of electronic devices to decorate the camera that may protrude from the back cover 40, ensuring the overall aesthetics of the electronic device. In this embodiment, the camera decorative element includes a camera decorative ring 20 and a lampshade 30. The lampshade 30 may refer to the lampshade 30 of a fill light located adjacent to the camera, serving a decorative purpose for the fill light. Optionally, as... Figure 7 As shown, the camera decorative ring 20 includes an annular metal ring 11, the shape and size of which 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. A conductive element 12 is disposed on one side of the lampshade 30. When the lampshade 30 is accommodated in the annular metal ring 11, the conductive element 12 on the lampshade 30 is connected to the annular metal ring 11. The connection method between the conductive element 12 and the annular metal ring 11 is as described in the previous embodiments and will not be repeated here.

[0045] In this embodiment, by providing a conductive element 12 on one side of the lampshade 30, when the lampshade 30 is housed within the annular metal ring 11 of the camera decorative ring 20, the conductive element 12 on the lampshade 30 can connect with the annular metal ring 11, thereby disrupting the original annular current mode generated by the annular metal ring 11 in the camera decorative element, reducing the energy coupled to the annular metal ring 11, and removing loop mode clutter outside the target frequency band, thus avoiding the influence of the camera decorative element on the antenna performance and effectively improving the antenna performance of the electronic device.

[0046] Optionally, the lampshade 30 can be fixed to the annular metal ring 11 by means of bonding, snap-fitting, screw connection or other methods. This application embodiment does not make specific limitations on this.

[0047] Alternatively, please refer to Figure 8The 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 element 12 is disposed on the side of the first reflective film 32 opposite to the second reflective film 33. In this way, the conductive element 12 is disposed on the outside of the lampshade 30, that is, exposed on the outer surface of the lampshade 30, thereby ensuring that when the lampshade 30 is housed within the annular metal ring 11, the conductive element 12 can connect with the annular metal ring 11, avoiding connection obstacles caused by the conductive element 12 being disposed inside the lampshade 30. Furthermore, the conductive element 12 is disposed on the side of the first reflective film 32 that is opposite to 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 element 12 is disposed between the first reflective film 32 and the back cover 40 of the electronic device. As mentioned above, the conductive element 12 has a certain degree of extensibility. This arrangement can protect the conductive element 12 through the first reflective film 32, the lampshade body 31, and the second reflective film 33, avoiding breakage and damage to the conductive element 12 due to its proximity to the outside of the electronic device.

[0048] It should be noted that the first reflective film 32 and the second reflective film 33 can be glued to both sides of the lampshade body 31 to assemble the lampshade 30.

[0049] Alternatively, please refer to further details. 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 has a perforated portion 320 for accommodating the conductive element 12, the shape of which matches the shape of the conductive element 12. For example, the conductive element 12 is T-shaped, and the perforated portion 320 is also T-shaped, thus forming a space for accommodating the conductive element 12. The first adhesive layer 322 is coated on one side of the first reflective film body 321. The annular decorative film 323 is connected to the first reflective film body 321 via the first adhesive layer 322. The conductive element 12 can also be connected to the first reflective film body 321 by adhesive bonding. The first reflective film body 321 is connected to the back cover 40 via the coated first adhesive layer 322, thereby ensuring the stable connection of the conductive element 12.

[0050] This application also provides an electronic device, which includes the decorative structure described above, and the decorative structure is disposed on the back cover of the electronic device. It should be noted that the electronic device provided in this application includes all the technical features of the above-described decorative structure and can achieve the same technical effect; therefore, to avoid repetition, it will not be described again here.

[0051] Alternatively, please refer to Figure 10 Taking a camera decorative component as an example, the camera decorative ring 20 of the camera decorative component further includes at least one grounding part 21, which is connected to the motherboard of the electronic device. Figure 10 As shown, the camera decorative ring 20 includes three grounding parts 21, all of which are connected to the spring contacts on the motherboard to enable motherboard return current, which helps to further improve the performance of the electronic device antenna.

[0052] Please refer to Figure 11 In this embodiment of the application, the lampshade 30 and the camera decorative ring 20 can be assembled in the following way:

[0053] ①: Assemble the camera decorative ring 20; ②: Assemble the lampshade 30 into the annular metal ring of the camera decorative ring 20 using a snap-fit ​​assembly method; as mentioned above, the conductive component 12 is disposed on one side of the lampshade 30, and after the lampshade 30 is assembled into the annular metal ring of the camera decorative ring 20, the conductive component 12 also achieves connection with the annular metal ring 11. The inner wall of the annular metal ring may have a slot 22, and the end of the conductive component 12 and the insulating components disposed at the end (such as the first insulating component 123, the second insulating component 124, and the third insulating component 125 mentioned above) can be inserted into the slot 22, thereby achieving the connection between the conductive component 12 and the annular metal ring in the camera decorative ring 20, thus obtaining the structure shown in ③. ④: Through Figure 7 The second adhesive 50 shown attaches the camera decorative ring 20 with the lampshade 30 attached to the back cover 40 of the electronic device, and fixes the camera decorative piece to the back cover 40 of the electronic device with screws, thereby ensuring the secure installation of the camera decorative piece and the back cover 40.

[0054] Please refer to further details. Figure 7 After the lampshade 30 and the camera decorative ring 20 are fixed to the back cover 40 with the second adhesive 50, the bracket 60 is then glued together with the back cover 40 and the camera decorative ring 20, and can be further fixed with screws; a protective cover 70 can also be set 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.
