Description

Technical Field

[0001] This utility model relates to an integrated bracket antenna, belonging to the technical field of computer built-in antennas. Background Technology

[0002] With the development of laptops, many laptops have adopted all-metal casings to improve the strength of the outer shell structure. While metal casings enhance robustness, they also shield the internal antennas, resulting in very limited space for antenna placement. At the same time, laptops are developing towards thinner, lighter, and higher-performance designs, leading to increasingly compact internal spaces. This requires antenna designs to be more compact, efficient, and adaptable to various complex internal structures.

[0003] Laptop built-in antennas mainly include PCB antennas, FPC antennas, and LDS antennas. PCB antennas are used for direct integration, requiring dedicated storage space within the laptop, which is difficult to meet in laptops with all-metal casings and limited space. FPC antennas use flexible bonding between two flat transition surfaces, but cannot adapt to complex antenna arrangements in non-planar areas. Although LDS antennas can be molded on irregular three-dimensional bodies, they are more expensive, and when mounted on smaller structural components, space is limited, making it difficult to meet antenna performance requirements.

[0004] Some structural components of laptops, such as hinges, heat sinks, and speaker mounts, have inherent space and structural characteristics. Integrating antenna functionality into these components can be explored to fully utilize limited space. For example, the heat sink bracket in the cooling channel can be modified by adding an antenna support section for mounting a laser antenna, thus meeting the three-dimensional performance requirements for antenna mounting.

[0005] Against this technological backdrop, computer stand antennas have emerged, combining antenna functionality with the computer stand structure. This not only solves the problem of metal casing shielding the antenna but also achieves good antenna performance within a limited space, while simultaneously providing structural support, improving the utilization of the laptop's internal space, and reducing overall costs.

[0006] This project focuses on the design of the support structure to ensure that it meets the requirements of internal positioning accuracy and locking stability, while also ensuring the reliability of its antenna performance. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0034] This utility model provides an integrated bracket antenna, such as Figures 1 to 5 As shown, it includes an antenna carrier, which includes a carrier plate 1 and a feed section bent plate 2 disposed on one side of the carrier plate 1.

[0035] The feed section bending plate 2 includes a first feed section bending edge 21, a second feed section bending edge 22, and a third feed section bending edge 23, which are linearly spaced. The first feed section bending edge, the second feed section bending edge, and the third feed section bending edge are respectively provided with a plurality of serrated bodies 3 that are spaced apart and bend towards the carrier plate. The feed section bending plate 2 is provided with a plurality of signal radiation connection ends 4, which are linearly spaced apart. Any signal radiation connection end is provided with a spring positioning hole 40.

[0036] The carrier plate 1 is provided with three extension ends 5 corresponding to the bending edges of the first feed section, the second feed section, and the third feed section. At least one extension end 5 is provided with a signal radiation bending edge 50. The carrier plate is provided with a plurality of positioning holes and slots 6.

[0037] Detailed implementation process and principle explanation:

[0038] An integrated bracket antenna is used to meet the strength requirements of the internal support structure of the computer and to realize the antenna function. It is mounted internally through several positioning holes and slots.

[0039] A linear distributed design with the first feed section bending edge 21, the second feed section bending edge 22, and the third feed section bending edge 23 is adopted, and the extension end 5 is used in corresponding cooperation to ensure the antenna performance and realize the adaptive array.

[0040] The spring-loaded positioning hole 40 of the signal radiation connection terminal 4 facilitates conductive engagement, and the design of the sawtooth body 3 and the signal radiation bending edge 50 increases the contact area with connecting components such as feeders, reduces contact resistance, makes signal transmission more stable and efficient, and reduces losses during signal transmission.

[0041] In addition, the sawtooth body 3 also meets the requirements for connection stability. For example, during welding and crimping, it increases the degree of engagement, improves the robustness of the connection, and has strong shock resistance. At the same time, it helps to adjust the input impedance of the antenna, making it better match the characteristic impedance of the feed line, reducing signal reflection, and improving power transmission efficiency.

[0042] The distributed sawtooth body 3 also increases the signal wavelength, resulting in a richer frequency band.

[0043] In one specific embodiment, the carrier plate 1 is provided with a transition plate 7, which includes a parallel connecting plate 71 connected to the feed section bending plate and arranged parallel to the carrier plate, and an inclined transition plate 72 connecting the parallel connecting plate and the carrier plate.

[0044] The transition portions of the parallel connecting plate 71 and the inclined transition plate 72, and the transition portions of the inclined transition plate 72 and the carrier plate 1, are respectively provided with a plurality of linearly distributed through holes 8.

[0045] Specifically, the through-hole slot 8 can provide significant heat dissipation performance. At the same time, the distribution of the through-hole slot 8 can change the propagation path and electromagnetic field distribution of electromagnetic waves in the antenna structure, and fine-tune the electromagnetic parameters such as the resonant frequency and bandwidth of the antenna to meet the design requirements.

[0046] In one specific embodiment, the transition plate 7 is provided with a plurality of mating cutouts 70.

[0047] It satisfies the positioning and passage of the locking device or mating part.

[0048] In one specific embodiment, the carrier plate 1 is provided with a plurality of foolproof guide positioning holes and slots 11.

[0049] The foolproof guide positioning slot 11 can prevent misalignment during assembly, and at the same time, it can cooperate with the guide post of the loading part to realize the assembly guide positioning during pre-assembly, ensuring the reliable accuracy of its mounting position.

[0050] In one specific embodiment, the two extended ends of the carrier plate 1 are respectively provided with signal radiation bending edges, and the two signal radiation bending edges have structural differences.

[0051] Specifically, by designing differentiated signal radiation bend edges, more sophisticated frequency band designs can be achieved. These structural differences include variations in the height of the signal radiation bend edges and / or differences in the width along the linear direction.

[0052] In one specific embodiment, the second feed section bend edge 22 is disposed between the first feed section bend edge and the third feed section bend edge; both ends of the feed section bend plate 2 are respectively provided with signal radiation connection ends 4, and both ends of the second feed section bend edge are respectively provided with signal radiation connection ends 4.

[0053] This distribution satisfies the design requirements for the alignment and fit of the feed lines.

[0054] In one specific embodiment, the signal radiation connection end 4 is a bent and folded composite structure, and the composite structure is provided with a through spring positioning hole.

[0055] The folded composite signal radiation connection terminal 4 ensures structural strength.

[0056] In one specific embodiment, the feed section bend plate 2 is provided with two mating windows 20 that are aligned one-to-one with the bending edges of the first feed section and the third feed section.

[0057] The mating window 20 is used for matching and limiting the internal assembly structure of the computer, making the mounting and locking position of the integrated bracket antenna more stable and reliable. Generally, the mating window 20 is used for the positioning and matching of the rotating shaft seat.

[0058] In one specific embodiment, the antenna carrier is a one-piece molded structure.

[0059] Specifically, it uses sheet metal for integral stamping and forming, and then bends and forms the relevant parts to meet the needs of mass production and effectively control costs.

[0060] As described above, this integrated bracket antenna, through its segmented distributed design and sawtooth structure, ensures conduction stability and reduces signal loss. The through-hole slot distribution in the transition plate aids in heat dissipation and allows for fine-tuning of the antenna's resonant frequency, bandwidth, and other electromagnetic parameters, meeting design requirements. It also satisfies the requirements for built-in positioning accuracy, assembly reliability, and conduction stability.

[0062] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
