Description

Technical Field

[0001] This utility model relates to the field of communication equipment technology, and in particular to a protective structure for a flat panel antenna. Background Technology

[0002] A flat panel antenna is an antenna that propagates only in a specific direction and is typically used in point-to-point communication scenarios; it is also known as a "patch antenna." In addition to the protective function of the housing itself, a protective structure is required on the outside of the flat panel antenna to further reduce damage caused by environmental and human factors, thereby reducing maintenance frequency and costs and improving equipment utilization efficiency.

[0003] Chinese Patent No. CN219717236U discloses a protective structure for a flat panel antenna, including a column and a flat panel antenna body fixed on the column. A clamp is bolted to the column, and the clamp is fixed to the outer shell of the flat panel antenna body via a connecting frame. A wind sensor is fixedly connected to the column. Two arc-shaped plates are arranged on the outer side of the flat panel antenna body to form a windproof cover for wind protection. A transmission component is provided on the column to move the arc-shaped plates. This protective structure forms a windproof cover structure on the outer side of the flat panel antenna body, preventing the antenna body from changing its orientation due to strong winds. This solves the problem in existing technologies where flat panel antennas lack an outer windproof structure, making them susceptible to slight changes in orientation during windy weather, thus affecting signal reception and transmission.

[0004] However, the above technical solution has the following shortcomings: When the device rotates the arc plate, although the transmission plate has the function of extension and retraction, the structural design not only affects the stability of the arc plate, but also increases the complexity of the internal transmission structure of the column, making it inconvenient to carry out maintenance and reducing the practicality of the protective structure. Utility Model Content

This structure not only provides good wind protection for the flat panel antenna but also avoids the drawbacks of unstable protective structures and facilitates maintenance of the protective structure.

[0006] The present invention provides a protective structure for a flat panel antenna, comprising a column and an opening / closing device. The column houses the flat panel antenna body and a door, with a wind deflector on the outer side of the antenna body. The opening / closing device includes a fixed frame mounted on the column, two mounting blocks symmetrically distributed on the fixed frame, a rotating arm rotatably connected to the mounting blocks and having a bent portion, a connecting rod mounted on the rotating arm, a connecting arm rotatably connected to the rotating arm, a rotating shaft rotatably connected to the fixed frame and having a threaded portion, and a movable block threadedly connected to the threaded portion. The end of the connecting arm furthest from the rotating arm is rotatably connected to the movable block, the rotating shaft is rotatably connected to the column, and the wind deflector is mounted on the connecting rod.

[0021] Example 1

[0022] like Figures 1-4 As shown, the protective structure of the flat panel antenna proposed in this embodiment includes a column 1 and an opening and closing device; the column 1 is provided with a flat panel antenna body 2 and a shell door 23, the flat panel antenna body 2 is provided with a clamp 24, the clamp 24 is snapped onto the column 1, and a wind baffle 3 is provided on the outside of the flat panel antenna body 2.

[0023] The opening and closing device includes a fixed frame 4 mounted on a column 1, two mounting blocks 5 symmetrically distributed on the fixed frame 4, a rotating arm 6 rotatably connected to the mounting blocks 5 and having a bent portion, a connecting rod 7 mounted on the rotating arm 6, a connecting arm 9 rotatably connected to the rotating arm 6, a rotating shaft 10 rotatably connected to the fixed frame 4 and having a threaded portion 11, and a moving block 12 threadedly connected to the threaded portion 11; the end of the connecting arm 9 away from the rotating arm 6 is rotatably connected to the moving block 12, the rotating shaft 10 is rotatably connected to the column 1, a wind deflector 3 is mounted on the connecting rod 7, and a magnet 21 is provided on each of the two wind deflectors 3, and the two magnets 21 are magnetically connected.

[0024] A support frame 13 is provided on the fixed frame 4, and the rotating shaft 10 is rotatably connected to the support frame 13. Two telescopic soft sleeves 14 are provided on the outer side of the threaded part 11. One telescopic soft sleeve 14 is provided on the fixed frame 4 and the moving block 12, and the other telescopic soft sleeve 14 is provided on the moving block 12 and the support frame 13. The telescopic soft sleeves 14 allow the moving block 12 to extend and retract with it when it moves, so as to always cover the threaded part 11 and ensure the service life of the device. A reinforcing rod 8 is provided on the rotating arm 6. The end of the reinforcing rod 8 away from the rotating arm 6 is provided on the wind deflector 3. The reinforcing rod 8 is used to improve the stability of the connection with the wind deflector 3 and improve the structural strength.

[0025] In this embodiment, when the wind force is strong, the rotating shaft 10 can be rotated to drive the threaded part 11 on it to rotate. The threaded part 11 is screwed into the moving block 12, and under the guidance of the connecting arm 9, the moving block 12 will move along the threaded part 11, causing the connecting arm 9 to rotate. Then, the end of the connecting arm 9 away from the moving block 12 drives the rotating arm 6 to rotate relative to it. Then, the rotating arm 6 drives the connecting rod 7 to rotate around the mounting block 5, so that the wind deflectors 3 on both sides move closer to each other until the two magnets 21 are magnetically connected. This not only achieves the protection of the flat antenna body 2, but also the main body of the device is located on the outside of the column 1. The transmission structure is simple and easy to maintain. It also avoids the influence of the automatic telescopic structure on the stability of the protective structure, and has good practicality.

[0026] Example 2

[0027] like Figure 3 and Figure 4 As shown, the protective structure of the flat panel antenna proposed in this embodiment has an improvement over the first embodiment. In this embodiment, the column 1 is equipped with a drive assembly, which includes a partition 15 inside the column 1, a motor 16 on the partition 15, a main shaft 17 rotatably connected to the partition 15, a first gear 18 coaxially mounted on the main shaft 17, and a second gear 19 coaxially mounted on the rotating shaft 10. The motor 16 and the main shaft 17 are driven together, the first gear 18 and the second gear 19 are meshed together, and a mounting ring 20 is coaxially mounted on the rotating shaft 10. The mounting ring 20 is rotatably mounted inside the column 1 and is used to limit the axial position of the rotating shaft 10.

[0028] In this embodiment, the main shaft 17 is driven to rotate by the motor 16, and the main shaft 17 drives the first gear 18 to rotate. The first gear 18 and the second gear 19 mesh to drive the rotating shaft 10 to rotate, thereby realizing the opening and closing of the wind deflector 3. At the same time, a wind sensor (not shown) can be set on the column 1 to control the forward and reverse rotation of the motor 16 according to the wind force, in conjunction with the controller.

[0029] Example 3

[0030] like Figure 1 and Figure 2 As shown in the figure, the protective structure of the flat panel antenna proposed in this embodiment has two symmetrically distributed fixing plates 22 on the column 1, compared with the first embodiment. The fixing plates 22 are located on the inner side of the windbreak plate 3.

[0031] In this embodiment, the fixing plate 22 is used to fill the gap between the wind baffle 3 and the column 1. Since the rotation center of the wind baffle 3 does not coincide with the axis center line of the column 1, in order to avoid the wind baffle 3 being blocked by the column 1 during the opening process, the wind baffle 3 needs to leave a certain gap with the column 1 in its design. When the wind baffle 3 is closed, the remaining gap will be blocked by the fixing plate 22. Both the wind baffle 3 and the fixing plate 22 are made of materials with good wave transmission, such as plastic and fiberglass, to avoid affecting the signal reception.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
