DETAILED DESCRIPTION

[0033] In order to make the purposes, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0034] An embodiment of the present invention provides an antenna structure, including a circuit board, an antenna body, and a communication module; a conductive circuit is formed on the circuit board body, and the conductive circuit replaces the physical wiring harness of the existing antenna, and the antenna body and the communication module are respectively connected to the two ends of the conductive circuit to achieve connectivity. Among them, each structure in the antenna structure is a standard part and can be assembled automatically, that is, the placement position and installation position of each standard part are fixed, and then automated equipment can be used for assembly operations.

[0035] The following describes in detail the various structures of the antenna structure provided by the embodiment of the present invention, as well as the positional relationship and connection relationship between the various structures, with reference to the accompanying drawings.

[0036] like Figures 1 to 8 As shown, in the embodiment of the present invention, the surface layer of the circuit board 10 includes two parallel conductive circuits 11 , one end of the conductive circuit 11 is connected to the antenna body 20 , and the other end is connected to the communication module 30 through the adapter 40 .

[0037] For example, circuit board 10 is a printed circuit board 10. During its fabrication, two conductive traces 11 are formed thereon for antenna signal transmission. One of the two conductive traces 11 is used for receiving signals, and the other for transmitting signals. The paths of conductive traces 11 are determined based on the design positions of antenna body 20 and communication module 30 on the motherboard, as well as the positions of other electronic components.

[0038] For example, two conductive traces 11 are arranged in parallel on the circuit board 10 and may include a bent portion or a curved portion.

[0039] Continue to refer Figures 1 to 8 As shown, in an embodiment of the present invention, the communication module 30 includes a communication circuit board 31, and two communication connectors 32 are provided on the communication circuit board 31; the two communication connectors 32 are connected to the conductive circuit 11 through an adapter 40, thereby realizing the connection between the communication module 30 and the circuit board 10.

[0040] As shown in the figure, the adapter 40 includes a base 41 and two conductors 42. The conductors 42 are arranged on the base 41. The base 41 includes a mounting surface 411. The first end of the conductor 42 is connected to the communication connector 32, and the second end passes through the mounting surface 411 and is used to connect to the conductive circuit 11.

[0041] The adapter 40 is mounted on the circuit board 10. Once securely installed, it simultaneously establishes electrical communication between the communication module 30 and the circuit board 10. Specifically, the base 41 includes two connecting portions 412 and a middle portion 413. The two connecting portions 412 are connected by the middle portion 413, and conductors 42 are disposed within each of the two connecting portions 412. The first ends of the conductors 42 extend outside the connecting portions 412 and connect to the antenna connector 43. The first ends of the conductors 42 are connected to the communication connector 32 via the antenna connector 43. The second ends of the conductors 42 include a first metal spring 44, which extends beyond the mounting surface 411 and is configured to connect to the conductive circuit 11.

[0042] The antenna connector 43 and the communication connector 32 are in a snap-fit ​​relationship. When connecting, the antenna connector 43 is snapped onto the communication connector 32 to achieve a tight connection between the two. For example, the antenna connector 43 and the communication connector 32 are male and female connectors, which can achieve a quick and stable connection.

[0043] The base 41 is fixedly connected to the circuit board 10. A first metal spring 44 extends from the mounting surface 411 of the base 41. After the mounting surface 411 is aligned with the surface of the circuit board 10, the first metal spring 44 presses against the conductive trace 11, thereby achieving a stable connection between the two. For example, a mounting hole 4131 is provided in the middle of the intermediate portion 413. The base 41 is connected to the circuit board 10 through the mounting hole 4131, for example, by using a screw stud to secure the connection.

[0044] Continue to refer Figures 1 to 8 As shown, in this embodiment of the present invention, the conductor 42 includes a metal core 421, which is sequentially coated with a dielectric layer 422, a metal braiding layer 423, and a waterproof jacket 424. The two ends of the metal core 421 are respectively connected to the antenna connector 43 and the first metal spring 44, thereby connecting the communication module 30 with the conductive circuit 11. For example, a shielding layer is provided between the metal braiding layer 423 and the protective jacket 424. The conductor 42 also includes an antenna grounding spring 45, one end of which is connected to the metal braiding layer 423, and the other end of which extends through the mounting surface 411 and is used to connect to the ground wire of the circuit board 10. The antenna grounding spring 45 can be used to partially ground the adapter 40. The grounding operation helps increase the output power of the signal and ensure the stability of signal transmission.

[0045] Continue to refer Figures 1 to 8As shown, in this embodiment of the present invention, base 41 further includes a shielding cover 414, which is positioned over the outside of conductor 42 and connected to connector 412. Shielding cover 414 includes a shielding grounding spring 4141, one end of which extends beyond mounting surface 411 and is connected to the ground of circuit board 10. Shielding cover 414 isolates conductor 42 from the outside world, preventing electromagnetic interference. Shielding grounding spring 4141 grounds shielding cover 414, helping to ensure a uniform and stable magnetic field.

[0046] The bottom of the edge of the shielding cover 414 is fixedly connected to the base 41 and can be fixed by a snap connection. For example, the bottom of the shielding cover 414 is provided with an extended snap or buckle edge, which is fixedly connected to the base 41 through the snap or buckle edge.

[0047] For example, the antenna grounding spring 45 and the shielding grounding spring 4141 extend to the middle portion 413; the antenna grounding spring 45 and the shielding grounding spring 4141 are located in the middle portion 413 and connected to the ground line of the circuit board 10. Alternatively, for example, the antenna grounding spring 45 and the shielding grounding spring 4141 are located on either side of the mounting hole 4131. This structural layout is rational, more effectively utilizing the structural space in the middle portion 413, and preventing the base 41 from being too large.

[0048] Continue to refer Figures 1 to 8 As shown, in this embodiment of the present invention, the antenna body 20 includes an antenna circuit board 21, on which a second metal spring 22 is disposed. The antenna circuit board 21 is connected to one end of the conductive trace 11 via the second metal spring 22. A mounting position for the antenna body 20 is provided on the circuit board 10, and the antenna circuit board 21 is fixed to the mounting position, for example, using screws. When the antenna body 20 is mounted on the circuit board 10, the second metal spring 22 is simultaneously fixedly connected to the conductive trace 11 on the circuit board 10.

[0049] Embodiments of the present invention also provide a motherboard including the aforementioned antenna structure. Furthermore, electronic products including the aforementioned antenna structure or motherboard are provided. The circuit board 10 in the antenna structure is part of the motherboard's circuit board 10; that is, the conductive trace 11 is provided on the motherboard's circuit board 10.

[0050] Taking a laptop computer as an example, the motherboard is set in the shell of the system end of the laptop computer. When designing the system end, the position of the antenna structure and the communication module 30 on the motherboard is determined. According to the positional relationship between the antenna structure and the communication module 30, the path of the conductive circuit 11 on the motherboard is determined, and the conductive circuit 11 can also be changed according to the position of other electronic components on the motherboard.

[0051] The antenna structure is connected to the conductive circuit 11 via the second metal spring 22, and the communication module 30 is connected to the conductive circuit 11 via the adapter 40. In the above structure, the antenna structure and the communication module 30 are both of regular shape. If automated assembly is required, the above structure can be grasped, moved, and assembled by an automated gripping structure such as a robot, thereby achieving automated assembly.

[0052] The present invention provides an antenna structure, motherboard, and electronic product that eliminates the need for a physical wiring harness. Instead, a conductive circuit 11 is positioned on a circuit board 10. The antenna body 20 and a communication module 30 are connected to the ends of the conductive circuit 11, thereby achieving connectivity between the antenna body 20 and the communication module 30. The communication module 30 and the conductive circuit 11 are connected via an adapter 40. This technical solution eliminates the need for a physical wiring harness, allowing for automated installation of the antenna structure. This not only improves overall assembly efficiency but also reduces costs and increases product yield.
