Description

Technical Field

[0001] This application relates to the technical field of antennas, and particularly to a multi-system broadband directional antenna. Background Art

[0002] A broadband directional antenna refers to an antenna that has a relatively wide bandwidth and can limit the direction of radio wave transmission or reception to a specific direction. It combines the advantages of a wide frequency band and a directional band and is suitable for various communication scenarios. The working principle of a directional antenna is based on the radiation pattern and polarization mode of the antenna. By changing the shape, size, radiation pattern, and polarization mode of the antenna, the direction and intensity of the transmitted and received signals can be controlled.

[0003] The optimal signal can be obtained by adjusting the elevation angle and azimuth angle of the antenna. The elevation angle refers to the angle between the antenna and the horizontal plane, which can control the coverage range of the signal in the vertical direction. Generally speaking, increasing the elevation angle can expand the signal coverage range, but it may also lead to a decrease in signal strength. Therefore, it needs to be adjusted according to actual needs. The azimuth angle refers to the rotation angle of the antenna on the horizontal plane. By adjusting the azimuth angle, the propagation direction of the signal in the horizontal direction can be changed. To achieve the best signal coverage, the azimuth angle should be adjusted according to the position and direction of the target area.

[0004] Existing multi-system broadband directional antennas are installed through brackets and the elevation angle or azimuth angle is adjusted by rotating the motor. However, there are still certain drawbacks in the adjustment method supported only by the rotating shaft. Although the angle can be adjusted quickly, since the antenna is installed outdoors, the stability of signal reception will still be affected in bad weather. For this reason, this application proposes a multi-system broadband directional antenna. Summary of the Invention

[0042] Embodiment

[0043] As Figures 1 - 7 shown, a multi-system broadband directional antenna proposed by the present application includes an antenna body. The antenna body includes a PCB board body 1 and a plurality of antenna elements 2 arranged on the PCB board body 1. A coaxial cable 3 is also arranged on the PCB board body 1. It further includes a support top block 5. The PCB board body 1 is fixed to the upper end of the support top block 5 through an axial support member 4. A pitch angle adjustment mechanism 9 is arranged at the bottom end of the support top block 5; the pitch angle of the antenna is adjusted through the pitch angle adjustment mechanism 9, and the operation is simple and fast.

[0044] A dynamic support mechanism 10 is also arranged between the support top block 5 and the pitch angle adjustment mechanism 9, which is used to support the support top block 5 in multiple states after rotation, so that the support top block 5 remains in a stable support state after adjusting the angle, and further enables the antenna to maintain a stable signal reception state. An azimuth adjustment mechanism 8 is arranged at the bottom end of the pitch angle adjustment mechanism 9, and the azimuth adjustment mechanism 8 is supported and fixed by a pole 11.

[0045] Specifically, the pitch angle adjustment mechanism 9 includes a steering support plate 97 connected to the bottom end of the support top block 5. The bottom end of the steering support plate 97 is an arc portion, and an incomplete gear 98 is fixedly sleeved on the arc 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 top block 5 have a sufficient support area, making the entire support state more stable.

[0046] Further, the pitch angle adjustment mechanism 9 further includes an articulated support block 91. A groove 92 is formed at the upper end of the articulated support block 91. One end of the groove 92 is fixedly connected to an L-shaped support plate 95. 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 and drives the incomplete gear 98. An air 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 air 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 air cylinder 96 is started, so that the telescopic end of the air cylinder 96 extends, thereby driving the L-shaped sliding plate 94 and the transmission rack 93 to move in the direction close to the PCB board body 1, making the transmission rack 93 mesh with and drive the incomplete gear 98, so that the angle between the support top block 5 and the PCB board body 1 changes until the angle for optimal signal reception is satisfied.

[0047] Among them, the dynamic support mechanism 10 includes two pairs of vertical sliding grooves 106 formed at the upper end of the articulated support block 91. The two pairs of vertical sliding grooves 106 are respectively located on both sides of the groove 92. A vertically arranged support frame plate 104 is slidably connected in each of the two pairs of vertical sliding grooves 106. Limiting inner grooves are provided on the inner walls of the two pairs of vertical sliding grooves 106. Limiting blocks are fixedly connected to both side walls of the two support frame plates 104. The corresponding limiting blocks slide in the corresponding limiting inner grooves, so that the support frame plate 104 will not break away from the articulated support block 91 and maintains a stable connection state. It should be noted that the support frame plate 104 is in an inverted U shape. A pair of passive racks 105 are fixedly connected to the mutually approaching ends of the two support frame plates 104. The two pairs of passive racks 105 are both meshed with and driven by the incomplete gear 98. A pair of buffer grooves 101 are formed at the bottom end of the support top block 5. An inverted U-shaped slider 102 is slidably connected in each of the two buffer grooves 101. A connecting block 103 is rotatably connected in each of the two inverted U-shaped sliders 102. The two connecting blocks 103 are respectively connected to the top ends of the two support frame plates 104. After the angle of the support top block 5 changes when the transmission rack 93 meshes with and drives the incomplete gear 98, the connecting block 103 on the side close to the PCB board body 1 rises, and the connecting block 103 on the side far from the PCB board body 1 slides downward, so as to change the support states of the two connecting blocks 103 as the angle of the support top block 5 changes.

[0048] The azimuth adjustment mechanism 8 includes a support housing 81 fixedly connected to the upper end of the clamping groove 7. A servo motor 84 is installed inside the support housing 81. The output end of the servo motor 84 is fixedly connected to a rotating shaft 82, and the rotating shaft 82 is fixedly connected to the connecting support block 91. The bottom end of the connecting support block 91 is fixedly connected to a support sliding cylinder 83. An annular groove is also formed at the upper end of the support housing 81, and the support sliding cylinder 83 is slidably connected in the annular groove to play a role in balancing and supporting the connecting support block 91. Among them, the servo motor 84 is electrically connected to an external power source. By starting the servo motor 84, the azimuth angle of the antenna is changed, and under the action of the support sliding cylinder 83, the connecting support block 91 and the support top block 5 maintain a stable support effect.

[0049] In this embodiment, a side support strip 6 is fixedly connected to one side of the upper end of the support top block 5 close to the PCB board body 1, and a clamping groove 7 is formed on the other side of the upper end of the support top block 5 far from the PCB board body 1. Among them, the axial support member 4 includes an axial support plate 41 fixedly connected to the side of the PCB board body 1. A U-shaped support plate 42 is fixedly connected to the side wall of the axial support plate 41 far from the PCB board body 1. The axial support plate 41 supports on the upper end of the side support strip 6, and the U-shaped support plate 42 supports in the clamping groove 7. The axial support plate 41 and the side support strip 6 are fixed by bolts 43, and the U-shaped support plate 42 is also fixed in the clamping groove 7 by bolts 43. A positioning convex rod 44 is fixedly connected to the middle of the lower end of the axial support plate 41, and a positioning groove is formed on the side support strip 6. The positioning convex rod 44 is inserted into the positioning groove. This enables the antenna to be quickly installed and fixed to the support top block 5.

[0050] The working principle of this embodiment is as follows: First, the pole 11 is installed at a specified position (the installation structure at the bottom of the pole 11 is not shown in the figure). Next, the positioning convex rod 44 is inserted into the limiting groove on the side support strip 6. At this time, the U-shaped support plate 42 just overlaps in the clamping groove 7, and the upper and lower threaded holes correspond one by one, so that a number of bolts 43 can be quickly screwed in to fix the axial support member 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 to drive the rotating shaft 82 to rotate. The angular change of the rotating shaft 82 drives the connecting support block 91 and the support top block 5 to synchronously complete the change of the azimuth angle until the required adjusted azimuth angle is reached.

[0051] When it is necessary to adjust the elevation angle of the antenna, the cylinder 96 is started. The telescopic end of the cylinder 96 extends to drive the L-shaped slide plate 94 to slide synchronously with the transmission rack 93, so that the transmission rack 93 meshes with the incomplete gear 98 for transmission, changing the angle of the steering support plate 97. Finally, the elevation angle of the antenna is changed through the support top block 5 (slowly adjust during the adjustment process until the elevation angle for the best signal reception is adjusted). Since the dynamic support mechanism 10 is provided between the support top block 5 and the connection support block 91, when the angle of the incomplete gear 98 changes, the incomplete gear 98 meshes with the two pairs of passive racks 105 for transmission, driving the support frame plate 104 on the side away from the PCB board body 1 to slide downward and the support frame plate 104 on the side close to the PCB board body 1 to slide upward, automatically changing the support heights of the two support frame plates 104, so that the top support heights of the two support frame plates 104 meet the support state after the elevation inclination of the support top block 5, keeping the support top block 5 in a stable signal reception state all the time. During the signal reception process, it will not be affected by external factors. The structural design is ingenious and can complete the adjustment and installation accurately and quickly.

[0052] The above specific embodiments are only the preferred embodiments of the present application. Based on the technical solution of the present application and the relevant inspirations 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 only explanations of the present application and do not limit the present application.
