Description

Technical Field

[0002] With the rapid development of modern wireless communication technology and the increasing use of smart devices, these devices are equipped with wireless communication modules and corresponding antennas to achieve wireless communication. Plastic whip antennas are currently widely used. Different types of antennas are typically designed inside the plastic whip sleeve, with the main body of the antenna structure including PCB boards and metal tubes. To ensure stable antenna performance, a plastic base plug is used for positioning and fixation. Previously, common methods included using square gaps to fix antennas with PCB boards as the carrier. Different customers had different requirements for PCB board thicknesses, leading to different internal designs for the base plug. Conversely, some customers required antennas with metal tube carriers, necessitating other types of base plugs. This resulted in the need for multiple injection molds, multiple base plug products, wasted costs, management chaos, and reduced efficiency.

[0055] like Figures 1 to 3 As shown, this utility model provides a fixed structure for an antenna system, which includes a base 1 and a mounting bracket 2 connected to the base 1.

[0056] Both the base 1 and the card holder 2 are cylindrical, and the base 1 and the card holder 2 are coaxially arranged, with the outer diameter of the base 1 being larger than the outer diameter of the card holder 2. Preferably, the base 1 and the card holder 2 are integrally injection molded structures.

The first engaging space 21 extends through the card holder 2 from its center along both the axial and radial directions of the card holder 2. The second engaging space 22 extends through the card holder 2 along its axial direction and is cylindrical. The first engaging space 21 is a square gap.

[0058] The component to be clamped is held in the first clamping space 21 or the second clamping space 22. The component to be clamped in this invention includes a PCB board and a metal tube.

[0059] Further, the first engaging space 21 includes a first engaging cavity 211, a second engaging cavity 212, and a third engaging cavity 213 connected in sequence, wherein the widths of the first engaging cavity 211, the second engaging cavity 212, and the third engaging cavity 213 decrease sequentially outward from the base 1. In one embodiment, the widths of the first engaging cavity 211, the second engaging cavity 212, and the third engaging cavity 213 are respectively matched to the components to be engaged with different thicknesses. The component to be engaged is a PCB board. Please refer to [link / reference]. Figure 4 The width of the first engaging cavity 211 corresponds to the engaging thickness of a PCB board 31 of 1.0 mm; please refer to [link / reference]. Figure 5 and 6 The width 212 of the second engagement cavity corresponds to the engagement thickness of 0.8mm on PCB board 32; please refer to [link / reference]. Figure 7 The width of the third engaging cavity 213 corresponds to the engaging thickness of a PCB board 33 with a thickness of 0.6mm. It should be noted that the thickness of the PCB board in this invention includes, but is not limited to, 0.6mm, 0.8mm, and 1.0mm.

[0060] Please continue reading. Figures 1 to 3The length of the second engaging space 22 is the same as the length of the card holder 2, and the periphery of the card holder 2 forms a third engaging space 23. In this invention, the second engaging space 22 is designed as a cylinder, forming a double-cylindrical structure with the third engaging space 23. The inner diameter of the second engaging space 22 is smaller than the inner diameter of the third engaging space 23, and the thickness of the second engaging space 22 matches the thickness of the parts to be engaged, thus allowing two metal tubes of different diameters to be securely engaged within the second and third engaging spaces respectively. Please refer to [link / reference]. Figure 8 and Figure 9 The width of the second engaging space 22 corresponds to the engaging diameter of a metal tube 41 of 5 mm; please refer to [link / reference]. Figure 10 and Figure 11 The width of the third engaging space 23 corresponds to the engaging diameter of a metal tube 42 with a diameter of 7mm. It should be noted that the diameter of the metal tube in this invention includes, but is not limited to, 7mm and 5mm.

[0061] Please continue reading. Figure 1 and Figure 2 The base 1 has a through hole 11 that extends through the base 1 and the card holder 2 along the axial direction of the base 1. External devices are electrically connected to the PCB board or metal tube through this through hole 11.

[0062] Please see Figures 12 to 18 This utility model also provides an antenna system, which includes a sleeve 5 and the aforementioned fixing structure.

[0063] The sleeve 5 has an opening 511 and an inner cavity 521 communicating with the opening 511. The sleeve 5 is a whip-shaped sleeve. The sleeve 5 includes a head 51 and a shaft 52. The opening 511 is located at the head 51, and the outer side of the opening of the head 51 has external threads. Along the axial direction of the sleeve 5, the diameter of the shaft 52 decreases from the head 51 to the other end.

[0064] The outer diameter of the base of the fixed structure matches the inner diameter of the opening of the sleeve.

[0065] like Figures 14 to 18 As shown, it is a schematic diagram of the structure in which different components are engaged in the card holder 2 of the fixed structure. The fixed structure is housed in the inner cavity of the sleeve 5, and the base 1 of the fixed structure is engaged inside the opening 511.

[0066] Furthermore, the base 1 is flush with the opening side of the rod sleeve 5.

[0067] This invention's fixing structure is designed to accommodate both PCB board antenna structures and metal tube antenna structures in antenna design, while also being compatible with different PCB board thicknesses and metal tube diameters. This fixing structure, used in conjunction with a plastic whip-shaped sleeve, forms the external protection and internal support structure for the antenna. Different antenna configurations can be designed within the sleeve to meet diverse application requirements. The antenna structure can be either a PCB board-based structure or a metal tube structure. To ensure stable antenna performance, it must be securely fixed. This invention utilizes a single fixing structure suitable for different antenna structures, reducing the number of molds required and lowering costs.

[0068] The fixing structure of this invention features a stepped design on the inner side, allowing for variations in the width of different engagement cavities within the first engagement space. This enables PCB boards of varying thicknesses to be vertically inserted and fixed in place by matching the width of the engagement cavity. Furthermore, the mounting base of this invention is designed with a double-cylinder structure, which can securely engage two metal tubes of different diameters within the second and third engagement spaces, respectively. This results in a universal antenna system fixing structure applicable to various types and sizes of antenna structures, thereby reducing costs and facilitating production control.
