Through the combination of these antenna units, the antenna array can achieve more efficient and accurate performance in receiving or transmitting signals, especially in terms of directivity, gain, and coverage. Chinese Patent (Announcement No. CN115732931 A) discloses an antenna array device, in which a substrate is mounted on a ground plane, the antenna array is mounted on the substrate, and multiple patch elements are mounted on the substrate and arranged around the antenna array.

[0027] like Figure 1-4 As shown, this utility model provides an antenna array, which includes:

[0028] A substrate 1 and antenna units 2 are arranged in a rectangular array on the substrate 1. A quick-release mechanism is provided on two opposite sides of each antenna unit 2 to enable rapid assembly and disassembly between each antenna unit 2 and the substrate 1. The quick-release mechanism includes a first component 3 and a second component 4. The first component 3 is provided on two opposite sides of each antenna unit 2, and the second component 4 is correspondingly provided on the substrate 1 near each antenna unit 2, with a slidable connection between the second component 4 and the substrate 1. The first component 3 and the second component 4 are detachably connected. Figure 1-4As shown, an antenna array has a substrate 1 made of an insulating material (such as Teflon or epoxy resin) as a printed circuit board. A ground plane is provided at the bottom of the substrate, and the connection between the ground plane and the substrate 1 can be by bonding or snap-fit. The ground plane is made of copper foil. The antenna elements 2 are arranged in a rectangular array, which effectively improves the signal transmission and reception performance of the antenna array. Quick-release mechanisms are respectively provided on two opposite sides of a pair of antenna elements 2 to achieve quick assembly and disassembly between each antenna element 2 and the substrate 1. The quick-release mechanism includes a first component 3 and a second component 4. The first component 3 is respectively provided on two opposite sides of the antenna elements 2, and the second component 4 is corresponding to the first component 3 and is provided on the substrate 1 near each antenna element 2. The second component 4 and the substrate 1 are slidably connected, and the first component 3 and the second component 4 are detachably connected. With this design, when it is necessary to disassemble the antenna unit 2, simply separate the first component 3 and the second component 4, and then slide the second component 4 along the substrate 1 to remove the antenna unit 2 from the substrate 1; during installation, align the first component 3 of the antenna unit 2 with the second component 4 on the substrate 1, and then slide the second component 4 to the position where it connects with the first component 3 to complete the installation of the antenna unit 2. The operation is simple and quick.

[0029] The antenna array of the present invention greatly improves the replacement and maintenance efficiency of antenna element 2 by setting a quick-release mechanism, and reduces maintenance costs. The quick assembly and disassembly of antenna element 2 makes the layout and configuration of the antenna array more flexible and can meet the needs of different application scenarios.

[0030] In some embodiments, the substrate 1 is provided with a base hole 5 for each antenna unit 2, and a base ring 6 is provided near each base hole, and each antenna unit 2 and the corresponding base ring 6 are detachably connected;

[0031] The second component 4 is disposed on opposite sides of each of the base rings 6. For example... Figure 1-4 As shown, the connection between the base ring 6 and the substrate 1 can be in the form of bonding or snap-fit. This design further enhances the stability of the connection between the antenna unit 2 and the substrate 1, and also provides more assurance for the quick assembly and disassembly of the antenna unit 2. During installation, the base ring 6 acts as a guide, which is used to install the antenna unit 2 at the corresponding position on the substrate 1.

[0032] In some embodiments, a sharpened surface 7 is provided at the inner edge of each base ring 6 facing away from the substrate 1. For example... Figure 1-4 As shown, the sharpened surface 7 can improve the signal transmission performance of the antenna to a certain extent and reduce signal reflection and interference. At the same time, when the antenna unit 2 is installed on the substrate 1, the sharpened surface 7 plays a guiding role, so that the antenna unit 2 can be smoothly snapped into the base ring 6.

[0033] In some embodiments, the base ring 6 is provided with a U-shaped frame 8 near the second member 4, the opening of the U-shaped frame 8 facing the center of the base ring 6, the second member 4 is slidably connected to the U-shaped frame 8, and a limiting plate 9 is provided at the top of the U-shaped frame 8 so that the second member 4 is slidably connected between the U-shaped frame 8 and the limiting plate 9. Figure 1-4 As shown, this structural design ensures that the second component 4 can slide stably on the substrate 1, and prevents the second component 4 from detaching from the substrate 1 during the sliding process, thereby improving the reliability of the quick-release mechanism. The connection between the U-shaped frame 8 and the base ring 6 can be in the form of bonding or snap-fitting, and the connection between the U-shaped frame 8 and the limiting plate 9 can be in the form of bonding or snap-fitting.

[0034] In some embodiments, a rotating member 10 is provided between the first component 3 and the second component 4. One end of the first component 3 has a rotating part 11, and one end of the rotating member 10 is rotatably connected to the rotating part 11 via a rotating rod. The end of the second component 4 away from the first component 3 has a slot 12. When the first component 3 and the second component 4 abut against each other, the other end of the rotating member 10 extends into the slot 12. Figure 1-4 As shown, the quick connection and separation between the first component 3 and the second component 4 are achieved through the cooperation of the rotating part 10 and the slot 12, which further improves the assembly and disassembly efficiency of the antenna unit 2. The rotating part 11 and the rotating part 10 are connected by a rotating rod installed at one end of the rotating part 10, and then the rotating rod and the rotating part 11 are connected by rotation.

[0035] In some embodiments, a gap is left between the rotating member 10 and the slot 12. A limiting groove 13 is provided at the bottom of the slot 12 facing away from the substrate 1. A limiting block 14, adapted to the limiting groove 13, is provided on the rotating member 10 away from the first member 3. When the rotating member 10 slides into the slot 12, the limiting block 14 and the rotating member 10 are slidably connected to the two inner sides of the slot 12, respectively. After the rotating member 10 slides to the bottom of the slot 12, it rotates about the center of the rotating part 11 facing away from the substrate 1, causing the limiting block 14 and the limiting groove 13 to engage. Figure 1-4 As shown, when the rotating part 10 is slid to the bottom of the slot 12, the limiting block 14 and the limiting groove 13 are engaged by rotating the rotating part 10 in the opposite direction. At this time, the rotating part 10 is locked in the limiting groove 13 and the slot 12, and the positional relationship between the first component 3 and the second component 4 is locked, so that the connection between the first component 3 and the second component 4 is more secure, preventing loosening during use.

[0036] In some embodiments, a torsion spring 15 is fitted onto the rotating rod, with both ends of the torsion spring 15 abutting between the rotating member 10 and the first member 3, respectively. For example... Figure 1-4 As shown, the torsion spring 15 is commercially available. The function of the torsion spring 15 is to provide a restoring force after the rotating part 10 rotates, so that the limiting block 14 and the rotating part 10 can be more tightly engaged with the limiting groove 13 and the slot 12, further enhancing the stability of the connection between the first component and the second component 4. When disassembly is required, the two ends of the torsion spring 15 can be moved towards each other to disengage it.
