Description

Technical Field

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

[0002] With technological advancements, electronic devices such as mobile phones and tablets are becoming increasingly widespread and powerful. These devices include a housing assembly, which houses and mounts functional components such as circuit boards, batteries, and display modules. The housing assembly is typically injection-molded from a metal frame and a plastic border. Furthermore, to enable antenna functionality, related technologies incorporate metal antenna radiators embedded in the plastic border of the housing assembly.

[0003] However, the process of setting up an insert-type antenna structure on a plastic frame is quite complex and difficult. Therefore, the frame components in related technologies are difficult to manufacture. Utility Model Content

[0004] The purpose of this application is to provide a frame assembly and an electronic device that can solve the technical problem of the high difficulty in processing the frame assembly.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, this application discloses a frame assembly for use in electronic devices, comprising:

[0007] The frame and the frame body are separately provided, with the frame surrounding the outer periphery of the frame body.

[0008] A flexible circuit board antenna includes a relatively bent clamping plate segment and a feed extension plate segment. The clamping plate segment is clamped between the frame and the frame body, and the feed extension plate segment extends to the frame body and is electrically connected to the circuit board of the electronic device.

[0009] Secondly, this application discloses an electronic device, including a circuit board and the aforementioned frame assembly, wherein the circuit board is disposed on the frame body, and the feed extension segment of the flexible circuit board antenna is electrically connected to the circuit board.

[0010] In this embodiment, the flexible circuit board antenna has good bendability. Therefore, the flexible circuit board antenna includes a relatively bent clamping plate segment and a feed extension plate segment. The clamping plate segment is clamped between the frame and the main frame body, and the feed extension plate segment extends to the main frame body and is electrically connected to the circuit board of the electronic device. At this time, the clamping plate segment is close to the outside of the frame assembly, so the clamping plate segment can serve as the radiator of the antenna. The radiator is electrically connected to the circuit board through the feed extension plate segment, thereby realizing the antenna function. Compared with the frame assembly in related technologies, the frame assembly disclosed in this application has the flexible circuit board antenna portion directly clamped between the frame and the main frame body. Therefore, the frame assembly does not require plastic insert processing, thus reducing the manufacturing difficulty of related molds and the difficulty of setting up the antenna structure, thereby reducing the processing difficulty of the frame assembly.

Detailed Implementation

[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. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort 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 terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. 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] The frame components and electronic devices provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0026] Please refer to Figures 1 to 11 This application discloses a frame assembly 100, which is applied to an electronic device. The frame assembly 100 serves as the mounting base for the electronic device and is used to house and mount the functional components of the electronic device. The disclosed frame assembly 100 includes a frame 110, a frame body 120, and a flexible circuit board antenna 130.

[0027] The frame 110 is the outer edge of the frame assembly 100 and is an external component of the electronic device. The frame 110 and the frame body 120 are separate components, with the frame 110 surrounding the outer perimeter of the frame body 120. The frame 110 surrounds the outside of the frame body 120, which provides a mounting base for other components of the electronic device. For example, components such as the circuit board 200, display screen, and camera module are mounted on the frame body 120. In this application, the separate configuration of the frame 110 and the frame body 120 means that the frame 110 and the frame body 120 are processed separately, and then the frame 110 is assembled with the frame body 120. It can also be understood that the structure formed by the frame 110 and the frame body 120 in this application is an assembly component, not a one-piece injection-molded structure.

[0028] The flexible circuit board antenna 130 is used to connect to the circuit board 200 of an electronic device. The flexible circuit board antenna 130 is used to transmit and receive antenna signals. The flexible circuit board antenna 130 consists of at least a polyimide substrate and a metal circuit layer. The metal circuit layer is disposed on the polyimide substrate and serves as both the radiator and feed line of the antenna. The substrate layer of the flexible circuit board antenna 130 has a flexible structure, thus giving it good flexibility and allowing it to be bent. The fabrication process of the flexible circuit board antenna 130 is a known technology and is not limited herein.

[0029] The flexible circuit board antenna 130 includes a relatively bent clamping plate segment 1301 and a feed extension plate segment 1302, which are different regions of the same flexible circuit board antenna 130. The clamping plate segment 1301 is clamped between the frame 110 and the frame body 120, and the feed extension plate segment 1302 extends to the frame body 120 and is electrically connected to the circuit board 200 of the electronic device. In this application, the frame 110 is located outside the frame body 120. Therefore, the clamping plate segment 1301, which is clamped between the frame 110 and the frame body 120, is close to the outside of the frame assembly 100. Thus, the clamping plate segment 1301 can serve as the radiator of the antenna, specifically the metal circuit layer on the clamping plate segment 1301. The feed extension plate segment 1302 extends to the frame body 120 and is electrically connected to the circuit board 200 of the electronic device. Specifically, this refers to the electrical connection between the metal circuit board on the feed extension section 1302 and the circuit board 200. At this time, the current signal generated by the antenna radio frequency device on the circuit board 200 is transmitted to the clamping section 1301 through the feed extension section. The clamping section 1301 serves as the radiator of the antenna to radiate or receive electromagnetic waves, thereby realizing the antenna function.

[0030] Compared with the frame assembly 100 in related technologies, the frame assembly 100 disclosed in this application directly clamps part of the flexible circuit board antenna 130 between the frame 110 and the frame body 120 to serve as the radiator of the antenna. Therefore, the frame assembly 100 does not require plastic insert process, thereby reducing the manufacturing difficulty of the relevant molds of the frame assembly 100 and the difficulty of setting the antenna structure, thus reducing the processing difficulty of the frame assembly 100.

[0031] Furthermore, the frame assembly 100 disclosed in this application has a lower processing difficulty, which is beneficial to improving the production efficiency and yield of the frame assembly 100. In addition, the frame assembly 100 in related technologies requires CNC machining to process the radiator of the antenna during manufacturing, resulting in higher manufacturing costs. However, in this application, a portion of the flexible circuit board antenna 130 is directly clamped between the frame 110 and the frame body 120 to serve as the antenna radiator, thus avoiding the fabrication of a metal antenna and eliminating the need for CNC machining. This simplifies the structure and manufacturing process of the frame assembly 100, effectively reducing its manufacturing cost.

[0032] In one embodiment, both the frame 110 and the frame body 120 can be made of non-conductive materials, such as plastic, glass, ceramic, or other non-metallic materials. In this case, the frame 110 and the frame body 120 are individually made of non-conductive materials, and then the frame 110 and the frame body 120 are assembled.

[0033] Alternatively, in another solution, both the frame 110 and the frame body 120 can be made of metal. In this case, in order to avoid the metal frame from affecting the antenna, a gap needs to be provided on the frame 110, and a part of the clamping plate segment 1301 is opposite to the gap, so as to realize the transmission and reception functions of the antenna signal.

[0034] Alternatively, in another alternative solution, the frame 110 can be made of a non-conductive material, and the frame body 120 can be made of a metal material. For example, the frame 110 can be made of plastic. In this case, the plastic frame 110 is fitted onto the metal frame body 120. Alternatively, the frame body 120 can be a one-piece injection-molded structure of metal and plastic. This document does not limit the specific materials of the frame 110 and the frame body 120.

[0035] In one alternative embodiment, the frame 110 and the frame body 120 can be bonded together via an adhesive joint. This adhesive joint can be made of double-sided tape, glue, or other adhesive materials.

[0036] In another alternative embodiment, the frame 110 may be provided with a first snap-fit ​​portion 1101, and the frame body 120 may be provided with a second snap-fit ​​portion 1201, with the first snap-fit ​​portion 1101 and the second snap-fit ​​portion 1201 engaging in a snap-fit ​​manner. In this case, the frame 110 and the frame body 120 are connected by a snap-fit ​​mechanism. This snap-fit ​​arrangement provides both good connection strength and ease of installation and disassembly, thus giving the frame assembly 100 good assembly performance.

[0037] Optionally, one of the first snap-fit ​​portion 1101 and the second snap-fit ​​portion 1201 can be a snap-fit ​​groove, and the other can be a snap fastener. In this case, when the first snap-fit ​​portion 1101 and the second snap-fit ​​portion 1201 are engaged, at least a portion of the snap fastener's head is located within the snap-fit ​​groove, thereby achieving engagement. Alternatively, both the first snap-fit ​​portion 1101 and the second snap-fit ​​portion 1201 can be snap fastener structures. When engaged, the snap fasteners of the two fasteners mutually limit each other to achieve engagement.

[0038] This document discloses a specific structure of the frame 110 and the frame body 120. Of course, the frame 110 and the frame body 120 can also have other structures, which are not limited herein. Specifically, the frame body 120 may include a support portion 121 and a peripheral support 122. The peripheral support 122 may be disposed on one side of the surface of the support portion 121 and protrude from the support portion 121. Here, the peripheral support 122 is located at the edge of the support portion 121, so the peripheral support 122 can be understood as the edge of the frame body 120. The peripheral support 122 protrudes from the support portion 121, thus the support portion 121 and the peripheral support 122 form an L-shaped structure. The support portion 121 is the main structure of the frame body 120, used to support and install the functional components of the electronic device. The clamping plate segment 1301 of the flexible circuit board antenna 130 can be clamped between the frame 110 and the peripheral support 122.

[0039] The border 110 may include a border body 111 and an extension 112, the extension 112 being located on one side edge of the border body 111 and extending toward the frame body 120. At this time, the border body 111 and the extension 112 also form an L-shaped structure.

[0040] In this design, the L-shaped structure formed by the frame 110 and the L-shaped structure formed by the frame body 120 can abut against each other. Therefore, the peripheral support 122 can abut against the extension 112, enabling assembly positioning of the extension 112 and the peripheral support 122, thus improving the assembly accuracy of the frame 110 and the frame body 120. Furthermore, the extension 112 can limit the peripheral support 122, thus avoiding the risk of positional misalignment between the frame body 111 and the frame body 120 after assembly, thereby improving the assembly reliability of the frame assembly 100. In addition, the peripheral support 122 and the frame 110 form a bent assembly gap, further reducing the risk of external dust and moisture entering the frame assembly 100, thus improving the waterproof and dustproof performance of the frame assembly 100.

[0041] In the above scheme, the L-shaped structure formed by the frame 110 can partially cover the peripheral support 122. Alternatively, the extension 112 can be located on the side of the peripheral support 122 away from the bearing portion 121, with the frame body 111 surrounding the peripheral support 122.

[0042] In the above embodiment, the extension 112 can be located on the side of the frame body 111 facing the display module. In this case, the peripheral bracket 122 is also located on the side of the support portion 121 facing the display module. In another alternative embodiment, the frame assembly 100 may also include a back cover, which can be understood as a battery cover. In this case, the extension 112 can be located on the side of the frame body 111 facing the back cover, and the peripheral bracket 122 is also located on the support portion 121 facing the back cover. The back cover can be supported on the surface of the extension 112 on the side opposite to the peripheral bracket 122, so the extension 112 can also support the back cover.

[0043] To further improve the waterproof and dustproof performance of the frame assembly 100, in another alternative embodiment, the frame assembly 100 may also include a hot melt adhesive layer 140. The hot melt adhesive layer 140 can fill the space between the frame 110 and the frame body 120. Specifically, the hot melt adhesive layer 140 fills the space between the extension 112 and the peripheral support 122, thereby allowing the frame 110 and the frame body 120 to be bonded together via the hot melt adhesive layer 140. In the specific assembly process, liquid hot melt adhesive can be applied to the peripheral support 122 first, and then the frame 110 can be assembled onto the frame body 120. During the assembly of the frame 110, the extension 112 of the frame 110 compresses the liquid hot melt adhesive, causing the hot melt adhesive to flow and fill the gap between the extension 112 and the peripheral support 122. After the hot melt adhesive cures, it forms the hot melt adhesive layer 140, thereby connecting the frame 110 and the frame body 120 into a single unit.

[0044] In this solution, the hot melt adhesive is fluid and can penetrate all pores, so it can fill all the gaps between the extension 112 and the peripheral support 122, thereby ensuring that the frame 110 and the frame body 120 meet the IP68 airtightness requirement after assembly, thus giving the frame assembly 100 good waterproof and dustproof performance.

[0045] Furthermore, to further enhance the connection strength between the frame 110 and the frame body 120, the frame body 111 may be provided with the aforementioned first snap-fit ​​portion 1101, and one of the peripheral bracket 122 or the support portion 121 may be provided with a second snap-fit ​​portion 1201. In this case, the frame body 111 is snapped into the peripheral bracket 122 or the support portion 121 through the first snap-fit ​​portion 1101 and the second snap-fit ​​portion 1201. In this solution, the frame 110 and the frame body 120 are doubly fixedly connected by hot melt adhesive and buckles, which helps to improve the connection strength between the frame 110 and the frame body 120, thereby further improving the assembly safety and reliability of the frame assembly 100.

[0046] In the above scheme, the peripheral support 122 may have an outer side 1221, a top surface 1222, and an inner side 1223 connected in sequence, with the outer side 1221 and the inner side 1223 arranged opposite to each other. The frame body 111 is arranged around the outer side 1221, and the extension 112 is arranged opposite to the top surface 1222. The clamping plate segment 1301 can be clamped between the top surface 1222 and the extension 112 of the peripheral support 122.

[0047] In another alternative embodiment, the clamping plate segment 1301 may include a first plate segment 131 and a second plate segment 132 that are bent relative to each other, and the power supply extension plate segment 1302 may include a third plate segment 133 and a fourth plate segment 134 that are bent relative to each other. The second plate segment 132 is connected to the third plate segment 133 and is bent relative to each other. The first plate segment 131 may be clamped between the outer side 1221 of the frame body 111 and the peripheral support 122, the second plate segment 132 may be clamped between the extension 112 and the top surface 1222 of the peripheral support 122, the third plate segment 133 may be attached to the inner side 1223 of the peripheral support 122, and the fourth plate segment 134 may be attached to the bearing portion 121.

[0048] In this scheme, the clamping plate segment 1301 includes a first plate segment 131 clamped between the outer side 1221 of the frame body 111 and the peripheral support 122, and a second plate segment 132 clamped between the extension 112 and the top surface 1222 of the peripheral support 122. At this time, the area of ​​the clamping plate segment 1301 is relatively large. The clamping plate segment 1301 is used as a radiator. Therefore, the larger area of ​​the clamping plate segment 1301 is beneficial to improving the antenna function.

[0049] Furthermore, the circumferential dimension of the first plate segment 131 along the frame 110 can be larger than the circumferential dimensions of the second plate segment 132, the third plate segment 133, and the fourth plate segment 134 along the frame 110. In this design, the circumferential dimensions of the second plate segment 132, the third plate segment 133, and the fourth plate segment 134 along the frame 110 are limited by their location and cannot be set too large. The first plate segment 131 is located on the side of the electronic device, thus the side has a larger area, and increasing the area of ​​the first plate segment 131 can further improve the antenna performance of the electronic device. In addition, setting the circumferential dimension of the first plate segment 131 to be larger, and the circumferential dimensions of the other plate segments along the frame 110 to be smaller, is beneficial for achieving a thinner and lighter electronic device and facilitating the stacking and assembly of the electronic device.

[0050] In the above solution, during the assembly of the frame 110 and the frame body 120, the clamping force between the frame 110 and the frame body 120 causes the clamping plate segment 1301 to shift, resulting in poor assembly accuracy of the frame assembly 100. Therefore, in another optional solution, such as... Figure 7 and Figure 8 As shown, the clamping plate segment 1301 can be attached to the frame 110 via the first adhesive layer. This refers to attaching the flexible circuit board antenna 130 to the frame 110 via the first adhesive layer before assembling the frame 110 with the frame body 120. Then, as... Figure 2 Then, the border 110 and the frame body 120 are assembled.

[0051] In this design, the flexible circuit board antenna 130 is attached to the frame 110 via a first adhesive layer. This avoids the risk of the flexible circuit board antenna 130 shifting during the assembly of the frame 110 and the main frame 120, thus improving the assembly accuracy of the frame assembly 100. Simultaneously, it also avoids the risk of damage to the flexible circuit board antenna 130.

[0052] In another alternative embodiment, at least one clearance hole 1303 is provided at the connection point between the two relatively bent sections of the flexible circuit board antenna 130. The two relatively bent sections can be the clamping section 1301 and the feed extension section 1302, or any two adjacent sections from the first section 131, the second section 132, the third section 133, and the fourth section 134. In this embodiment, the clearance hole 1303 at the connection point between the two relatively bent sections reduces the bending stress between them, thus facilitating bending and reducing the risk of breakage at the bend.

[0053] In another alternative embodiment, the frame assembly 100 may further include a button module 150, which is used to control the electronic device. The button module 150 includes a button body 151 and a trigger circuit board 152. The user presses the button body 151, thereby pressing the trigger circuit board 200, which in turn triggers the trigger circuit board 152 to generate an electrical signal, thus controlling the corresponding function of the electronic device. The specific structure and principle of the button module 150 are well-known technologies and will not be elaborated upon herein.

[0054] like Figure 5 As shown, the frame 110 has a through hole 1102, and the button body 151 can be installed in the through hole 1102. Figure 9 and Figure 10 As shown, the trigger circuit board 152 can be bonded to the outer peripheral surface of the frame body 120 via the second adhesive layer 153. The second adhesive layer 153 can be double-sided tape, glue, or foam with adhesive properties. When the frame 110 is assembled with the frame body 120, the button body 151 is connected to the trigger circuit board 152.

[0055] In this design, the button body 151 and trigger circuit board 152 of the button module 150 are respectively mounted on the frame 110 and the frame body 120. The button body 151 and trigger circuit board 152 are then assembled after the frame 110 and frame body 120 are combined. This design simplifies the assembly process of the button module 150 and reduces the assembly difficulty of the frame body.

[0056] In one specific assembly scheme, a second adhesive layer 153 is first applied to the frame body 120. Then, the trigger circuit board 152 is applied along the side wall of the frame body 120, pressing it onto the second adhesive layer 153 to ensure the trigger circuit board 152 adheres to the frame body 120. Next, a ring of hot melt adhesive is applied to the frame body 120, passing over the surface of the trigger circuit board 152. While the hot melt adhesive is still wet, the frame 110 is assembled to the frame body 120. After the frame 110 is assembled, the hot melt adhesive fills all the gaps in the trigger circuit board 152, and upon curing, completely bonds the frame 110 and the frame body 120 together, thus achieving a complete seal of the frame assembly 100.

[0057] Furthermore, after the frame 110 is assembled, it is necessary to apply pressure to both the frame 110 and the frame body 120. Therefore, the frame 110 and frame body 120 need to be placed in a pressure-holding fixture for pressure holding. The pressure-holding fixture consists of an upper pressure-holding fixture and a lower pressure-holding fixture, clamping the frame assembly 100 in between. The purpose is to allow the hot melt adhesive to dry under pressure. This ensures the consistency of the assembled frame 110 and frame body 120, avoiding flatness or unevenness. The specific structure of the pressure-holding fixture and the pressure-holding process are conventional techniques, and therefore will not be elaborated upon in this article.

[0058] In another alternative embodiment, such as Figure 8 As shown, the clamping plate segment 1301 may also have a clearance hole 1301a. The hole on the frame 110 corresponding to the area of ​​the clamping plate segment 1301 is positioned opposite to the clearance hole 1301a. In this case, the clearance hole 1301a is used to expose the opening position on the frame 110, thereby avoiding obstruction of the opening on the frame 110. This avoids the risk of conflict between the antenna setting and the opening position of the frame 110, and is beneficial to optimizing the layout structure of the frame assembly 100. For example, the frame 110 usually has a through hole 1102 for mounting the button body 151 and a sound outlet hole. The clearance hole 1301a on the clamping plate segment 1301 can obstruct the through hole 1102 and the sound outlet hole, thereby exposing the through hole 1102 and the sound outlet hole.

[0059] In another alternative embodiment, the number of flexible circuit board antennas 130 can be multiple, and the multiple flexible circuit board antennas 130 can be arranged at circumferential intervals along the frame 110. This solution can further improve the antenna performance of electronic devices.

[0060] Based on the frame component 100 disclosed in the embodiments of this application, the embodiments of this application also disclose an electronic device, which includes the frame component 100 described in any of the embodiments above.

[0061] The electronic device disclosed in this application also includes a circuit board 200. The circuit board 200 can be a motherboard or a sub-board of the electronic device, and this is not limited thereto. The circuit board 200 is disposed on the frame body 120, specifically, the circuit board 200 is supported on the support portion 121 of the frame body 120. The feed extension segment 1302 of the flexible circuit board antenna 130 can be electrically connected to the circuit board 200.

[0062] The electronic devices disclosed in this application can be smartphones, tablets, e-book readers, wearable devices (such as smartwatches), video game consoles, etc. This application does not limit the specific types of electronic devices.

[0063] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
