The proposed technical solution includes an antenna body, which comprises a PCB board and several antenna elements mounted on the PCB board. A coaxial line is also mounted on the PCB board. A support block is also included. The PCB board is fixed to the upper end of the support block by an axial support member.

Description

Technical Field

[0001] This application relates to the field of antenna technology, and in particular to a multi-system broadband directional antenna. Background Technology

[0002] A broadband directional antenna is an antenna with a wide bandwidth that can direct radio wave transmission or reception in a specific direction. It combines the advantages of both wideband and directional band, making it suitable for various communication scenarios. The working principle of a directional antenna is based on its radiation mode and polarization. By changing the antenna's shape, size, radiation mode, and polarization, the direction and intensity of transmitted and received signals can be controlled.

[0003] The optimal signal acquisition of an antenna can be achieved by adjusting its elevation and azimuth angles. The elevation angle, the angle between the antenna and the horizontal plane, controls the signal coverage in the vertical direction. Generally, increasing the elevation angle expands the signal coverage area but may weaken the signal strength. Therefore, it needs to be adjusted according to actual needs. The azimuth angle is the angle of rotation of the antenna in the horizontal plane. Adjusting the azimuth angle changes the direction of signal propagation in the horizontal direction. To achieve optimal signal coverage, the azimuth angle should be adjusted according to the location and orientation of the target area.

[0004] Existing multi-system broadband directional antennas are mounted on brackets and their elevation or azimuth angles are adjusted by rotating a motor. However, this method of adjustment using only a rotating shaft has certain drawbacks. Although it allows for quick angle adjustments, the stability of signal reception is still affected in inclement weather conditions since the antenna is installed outdoors. Therefore, this application proposes a multi-system broadband directional antenna. Summary of the Invention

[0007] A dynamic support mechanism is also provided between the support block and the pitch angle adjustment mechanism for multi-state support of the support block after turning. An azimuth adjustment mechanism is also provided at the bottom of the pitch angle adjustment mechanism, and the azimuth adjustment mechanism is fixed by a support rod.

[0008] Preferably, the pitch angle adjustment mechanism includes a steering support plate connected to the bottom end of the support block, the bottom end of the steering support plate being an arc-shaped portion, and an incomplete gear being fixedly sleeved on the arc-shaped portion;

[0009] The pitch angle adjustment mechanism also includes a connecting support block. The upper end of the connecting support block has a groove. One end of the groove is fixedly connected to an L-shaped support plate. The upper end of the L-shaped support plate is slidably connected to an L-shaped sliding plate. The upper end of the L-shaped sliding plate is fixedly connected to a transmission rack. The transmission rack meshes with the incomplete gear for transmission.

[0010] Preferably, a cylinder located inside a groove is installed on one inner wall of the L-shaped support plate, and the telescopic end of the cylinder is fixedly connected to the end of the L-shaped slide plate.

[0011] Preferably, the dynamic support mechanism includes two pairs of vertical sliding grooves formed on the upper end of the connecting support block. The two pairs of vertical sliding grooves are respectively located on both sides of the groove, and a vertically arranged support frame plate is slidably connected in each pair of vertical sliding grooves.

[0012] The support frame is inverted U-shaped, and a pair of passive racks are fixedly connected to the ends of the two support frame plates that are close to each other. Both pairs of passive racks mesh with incomplete gears for transmission.

[0013] Preferably, a pair of buffer grooves are provided at the bottom of the support top block, and an inverted U-shaped slider is slidably connected in each of the two buffer grooves. A connecting block is rotatably connected in each of the two inverted U-shaped sliders, and the two connecting blocks are respectively connected to the top of the two support frame plates.

[0014] Preferably, the orientation adjustment mechanism includes a support housing fixedly connected to the upper end of the snap-fit ​​groove, a servo motor is installed inside the support housing, a rotating shaft is fixedly connected to the output end of the servo motor, and the rotating shaft is fixedly connected to the connecting support block.

[0015] Preferably, a support slide is fixedly connected to the bottom end of the connecting support block, and an annular groove is provided at the upper end of the support housing. The support slide is slidably connected in the annular groove to provide balanced support for the connecting support block.

[0016] Preferably, a side support strip is fixedly connected to the upper end of the support block near the PCB board, and a snap-fit ​​groove is provided on the upper end of the support block away from the PCB board.

[0017] Preferably, the axial support includes an axial support plate fixedly connected to the side of the PCB board, and a U-shaped support plate fixedly connected to the side wall of the axial support plate away from the PCB board. The axial support plate is supported on the upper end of the side support strip, and the U-shaped support plate is supported in the snap-fit ​​groove. The axial support plate and the side support strip are fixed by bolts, and the U-shaped support plate is also fixed in the snap-fit ​​groove by bolts.

[0019] Compared with the prior art, this application has the following beneficial technical effects:

[0020] This application sets up an elevation angle adjustment mechanism between the azimuth adjustment mechanism and the support top block. The elevation angle adjustment mechanism can quickly adjust the elevation angle of the directional antenna. By setting up a dynamic support mechanism driven by an incomplete gear between the connecting support block and the support top block, the support angle of the two support frames on the support top block can be changed simultaneously after the elevation angle of the directional antenna is changed. This ensures that the support top block maintains its original stable support effect after the angle is changed, so that the antenna always maintains a stable signal receiving state and will not be affected by external factors. The structure is ingeniously designed and can complete the adjustment accurately and quickly.

[0021] By setting an azimuth adjustment mechanism between the pitch angle adjustment mechanism and the locking slot, the azimuth angle can be adjusted as needed. By setting a support slide cylinder located outside the rotating shaft between the connecting support block and the support housing, the antenna will not wobble axially after multi-angle adjustment, thus maintaining the accuracy of signal reception.

[0022] By setting an axial support between the PCB board and the support top block, the installation steps are simple, the process is saved, and the system is balanced and stable. Attached Figure Description

[0042] Example

[0043] like Figures 1-7 As shown, this application proposes a multi-system broadband directional antenna, including an antenna body. The antenna body includes a PCB board 1 and a plurality of antenna elements 2 disposed on the PCB board 1. The PCB board 1 is also provided with a coaxial line 3 and a support top block 5. The PCB board 1 is fixed to the upper end of the support top block 5 by an axial support member 4. The bottom end of the support top block 5 is provided with a pitch angle adjustment mechanism 9. The pitch angle of the antenna can be adjusted by the pitch angle adjustment mechanism 9, which is simple and quick to operate.

[0044] A dynamic support mechanism 10 is also provided between the support top block 5 and the pitch angle adjustment mechanism 9. This mechanism is used to provide multi-state support for the support top block 5 after cornering, ensuring that the support top block 5 maintains a stable support state after the angle is adjusted, thereby ensuring that the antenna maintains a stable signal reception state. An azimuth adjustment mechanism 8 is also provided at the bottom of the pitch angle adjustment mechanism 9. The azimuth adjustment mechanism 8 is supported and fixed by a support rod 11.

[0045] Specifically, the pitch angle adjustment mechanism 9 includes a steering support plate 97 connected to the bottom end of the support block 5. The bottom end of the steering support plate 97 is arc-shaped, and an incomplete gear 98 is fixedly fitted onto the arc-shaped portion. The steering support plate 97 is T-shaped, so that the upper end of the steering support plate 97 and the lower end of the support block 5 maintain sufficient support area, making the entire support state more stable.

[0046] Furthermore, the pitch angle adjustment mechanism 9 also includes a connecting support block 91. A groove 92 is formed at the upper end of the connecting support block 91. An L-shaped support plate 95 is fixedly connected to one end of the groove 92. An L-shaped sliding plate 94 is slidably connected to the upper end of the L-shaped support plate 95. A transmission rack 93 is fixedly connected to the upper end of the L-shaped sliding plate 94. The transmission rack 93 meshes with the incomplete gear 98 for transmission. A cylinder 96 located inside the groove 92 is installed on one inner wall of the L-shaped support plate 95. The telescopic end of the cylinder 96 is fixedly connected to the end of the L-shaped sliding plate 94. When it is necessary to adjust the pitch angle of the broadband directional antenna, the cylinder 96 is activated, causing its telescopic end to extend. This moves the L-shaped sliding plate 94 and the transmission rack 93 closer to the PCB board 1, causing the transmission rack 93 to mesh with the incomplete gear 98 for transmission. This changes the angle between the support block 5 and the PCB board 1 until the optimal signal reception angle is achieved.

[0047] The dynamic support mechanism 10 includes two pairs of vertical grooves 106 formed on the upper end of the connecting support block 91. The two pairs of vertical grooves 106 are located on both sides of the groove 92. Vertically arranged support frame plates 104 are slidably connected within each pair of vertical grooves 106. Limiting grooves are provided on the inner walls of each pair of vertical grooves 106. Limiting blocks are fixedly connected to the side walls of each of the two support frame plates 104. The corresponding limiting blocks slide within their respective limiting grooves, thus preventing the support frame plates 104 from detaching from the connecting support block 91 and maintaining a stable connection. It should be noted that the support frame plates 104 are inverted U-shaped. A pair of driven racks 105 are fixedly connected to the ends of the two support frame plates 104 that are close to each other. Both pairs of driven racks 105 mesh with incomplete gears 98 for transmission. The bottom end of the support block 5 is provided with a pair of buffer grooves 101. Each buffer groove 101 has a sliding U-shaped slider 102, and each sliding U-shaped slider 102 has a rotatably connected connecting block 103. The two connecting blocks 103 are respectively connected to the top ends of the two support frame plates 104. When the transmission rack 93 meshes with the incomplete gear 98, causing a change in the angle of the support block 5, the connecting block 103 closer to the PCB board 1 rises, while the connecting block 103 farther from the PCB board 1 slides downwards, thus changing the support state of the two connecting blocks 103 as the angle of the support block 5 changes.

[0048] The azimuth adjustment mechanism 8 includes a support housing 81 fixedly connected to the upper end of the snap-fit ​​groove 7. A servo motor 84 is installed inside the support housing 81, and a rotating shaft 82 is fixedly connected to the output end of the servo motor 84. The rotating shaft 82 is fixedly connected to the connecting support block 91. A support slide cylinder 83 is fixedly connected to the bottom end of the connecting support block 91. An annular groove is also provided at the upper end of the support housing 81, and the support slide cylinder 83 is slidably connected in the annular groove to provide balanced support for the connecting support block 91. The servo motor 84 is electrically connected to an external power source. By activating the servo motor 84, the azimuth angle of the antenna is changed, and under the action of the support slide cylinder 83, the connecting support block 91 and the supporting top block 5 maintain a stable support effect.

[0049] In this embodiment, a side support strip 6 is fixedly connected to the upper end of the support top block 5 near the PCB board 1, and a snap-fit ​​groove 7 is formed on the upper end of the support top block 5 away from the PCB board 1. The axial support member 4 includes an axial support plate 41 fixedly connected to the side of the PCB board 1. A U-shaped support plate 42 is fixedly connected to the side wall of the axial support plate 41 away from the PCB board 1. The axial support plate 41 is supported on the upper end of the side support strip 6, and the U-shaped support plate 42 is supported in the snap-fit ​​groove 7. The axial support plate 41 and the side support strip 6 are fixed with bolts 43, and the U-shaped support plate 42 is also fixed in the snap-fit ​​groove 7 with bolts 43. A positioning protrusion 44 is fixedly connected to the lower center of the axial support plate 41, and a positioning groove is formed on the side support strip 6, into which the positioning protrusion 44 is inserted. This allows for quick installation and fixation of the antenna and the support top block 5.

[0050] The working principle of this embodiment is as follows: First, the support rod 11 is installed in the designated position (the bottom of the support rod 11 has an installation structure that is not shown in the figure). Next, the positioning protrusion 44 is inserted into the limiting groove on the side support plate 6. At this time, the U-shaped support plate 42 just overlaps in the snap-fit ​​groove 7, and the upper and lower threaded holes correspond one by one, so that several bolts 43 can be screwed in quickly to fix the axial support 4 to the upper end of the support top block 5. When the azimuth angle of the antenna needs to be adjusted, the servo motor 84 is started. The output shaft of the servo motor 84 rotates, which drives the rotating shaft 82 to rotate. The rotating shaft 82 changes angle, which drives the connecting support block 91 and the support top block 5 to complete the change of azimuth angle synchronously until it is rotated to the azimuth angle that needs to be adjusted.

[0051] When the antenna's elevation angle needs adjustment, cylinder 96 is activated. The telescopic end of cylinder 96 extends, causing the L-shaped sliding plate 94 to slide synchronously with the transmission rack 93. This causes the transmission rack 93 to mesh with the incomplete gear 98, changing the angle of the steering support plate 97. Finally, the support block 5 causes the antenna's elevation angle to change (adjusting slowly until the optimal elevation angle for signal reception is achieved). Because a dynamic support mechanism 10 is installed between the support block 5 and the connecting support block 91, when the angle of the incomplete gear 98 changes, the incomplete gear 98 meshes with two pairs of passive racks 105, causing the support frame plate 104 on the side away from the PCB board 1 to slide downwards, and the support frame plate 104 on the side closer to the PCB board 1 to slide upwards. This automatically changes the support height of the two support frame plates 104, ensuring that the top support height of the two support frame plates 104 meets the support state after the support block 5 is tilted, thus maintaining a stable signal reception state for the support block 5. It is not affected by external factors during signal reception, and its ingenious structural design enables precise and rapid adjustment and installation.

Based on the technical solutions of this application and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments. The above specific embodiments are merely explanations of this application and are not limitations on this application.
