Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in FIG. 1 , an antenna device 100 provided by an embodiment of the present invention includes an antenna body 10 , a base 20 , and a link 30 connecting the antenna body 10 and the base 20 . The antenna body 10 includes a casing 11 , the casing 11 includes a top surface and a bottom surface disposed opposite to each other, and the bottom surface is connected to the connecting rod 30 . The antenna device 100 according to the embodiment of the present invention does not require pole holding resources when installing the antenna main body 10 , which saves steps such as building a sky, an iron tower, and holding a pole, and improves the installation efficiency of the outdoor antenna main body 10 .

Wherein, the housing 11 may be in a cylindrical shape; of course, in some embodiments, it may also be in other shapes.

The housing 11 can be made of glass fiber reinforced plastic, PC plastic, or PVC plastic, etc. as a waterproof cover. That is, the position where the lightning rod is arranged on the top surface of the casing 11 also has a waterproof structure, and the annular side wall of the casing 11 connecting the top surface and the bottom surface also has a waterproof function. The outer surface of the housing 11 can be beautified.

In order to facilitate the transportation and transfer of the antenna device 100, the connecting rod 30 is configured as a telescopic rod. The telescopic rod includes a first end 31 and a second end 32 disposed opposite to each other, wherein the first end 31 is connected to the bottom surface of the housing 11 , and the second end 32 is connected to the base 20 . The first end 31 can be telescopically arranged relative to the second end 32 . The telescopic rod may include at least two (eg, two, three, four, etc.) telescopic sections, and its structure may be a telescopic structure similar to an umbrella rod, or other common telescopic structures, which will not be repeated here. In actual use, after the antenna device 100 is transported to the position to be installed, the telescopic rod is retracted to the height of a telescopic section, so that the construction personnel can directly connect the antenna main body 10 and the first end 31 of the telescopic rod on the ground. The connection makes it unnecessary for construction personnel to climb to a high place to install the antenna main body 10, thereby further shortening the construction period. After the connection between the antenna main body 10 and the telescopic rod is completed, the telescopic rod can be driven to stretch, and the antenna main body 10 rises to a high place.

The bottom surface and the first end 31 can be connected through the flange 80; of course, other common connection methods can also be used to achieve the connection, which will not be repeated. Specifically, a tray can be provided on the first end 31 of the telescopic rod, and the tray can be matched with the 80 . The flange 80 can be made of cast iron, and similarly, the tray can also be made of cast iron. Specifically, the flange 80 may have a hollow, and the tray may be connected to the flange 80 through the hollow.

The antenna device 100 further includes a driving member 40 connected to the second end 32 of the telescopic rod. The driving member 40 can drive the telescopic rod to extend or retract under the action of an external force, so as to increase or decrease the distance between the antenna body 10 and the base 20 . Specifically, the driving member 40 may be disposed in the base 20 .

In the embodiment of the present invention, the antenna body 10 includes an antenna assembly 12 accommodated in the housing 11 , and the antenna assembly 12 is used for transmitting or receiving wireless signals. The antenna device 100 further includes a host 50 . The host 50 is disposed in the base 20 and is electrically connected to the antenna assembly 12 . The host 50 can be used to provide power to the antenna assembly 12 .

Antenna device 100 includes wires that electrically connect antenna assembly 12 and host 50 . Of course, as a variant, wireless power transmission may be performed between the antenna assembly 12 and the host 50 .

The wires are arranged outside the connecting rod 30. In order to reduce the wind resistance and prevent the wires from being scattered, the wires can be set as bundled jumpers. As a modification, the lead wire may be provided inside the link 30 .

It should be noted that the length of the wire should not be less than the maximum stretched length of the telescopic rod, so as to avoid the length of the wire restricting the stretching of the telescopic rod. Of course, the length of the wire is preferably equal to the maximum stretched length of the telescopic rod. Specifically, the length of the wire can be 4 meters to 10 meters. Correspondingly, the maximum stretched length of the telescopic rod can be 4 to 10 meters. For example, when the length of the wire is 5 meters, the maximum stretched length of the telescopic rod is 5 meters.

In order to save the construction time for installing the antenna device 100 outdoors, the wire and the antenna body 10 should be integrated in the manufacturing process, and during the manufacturing process, the wire and the antenna body 10 should be sealed and connected to improve the waterproof and waterproof of the antenna device. dust level. The wires are detachably connected to the main body, and the wires can be electrically connected to the host 50 conveniently and quickly at the outdoor installation site.

The housing 11 also includes a side wall connecting the top surface and the bottom surface, and the wire can pass through one end of the side wall of the housing 11 close to the bottom surface and then connect to the antenna assembly 12 .

The antenna device 100 according to the embodiment of the present invention further includes a lightning protection device 70 . The lightning protection device 70 is a lightning protection rod and is disposed on the top surface of the housing 11 .

In this embodiment of the present invention, with reference to FIGS. 1 and 2 , the antenna assembly 12 may include a three-sided directional panel antenna 121 , and the extending direction of the three-sided directional panel antenna 121 in the housing 11 is the same as the extending direction of the housing 11 , and both clothed in the casing 11 . Specifically, the cross section of the housing 11 is equally divided into three sectors (each sector is 120 degrees) with the center of the circle as the center, and the three-sided directional plate antennas 121 are respectively installed in the three sectors. Of course, the antenna assembly 12 may also include only one-sided directional panel antennas, or two-sided directional panel-shaped antennas, four-sided directional panel-shaped antennas, and the like.

Each directional patch antenna includes two channels. When the antenna assembly 12 includes three directional patch antennas, correspondingly, as shown in FIG. N-shaped connectors 62 are made at both ends of the feeder 61 for connecting the antenna assembly 12 and the host 50 respectively. Both ends of each feeder 61 are provided with signal labels 63 , and the signal labels 63 can be sleeved on the feeder 61 . The middle parts of the six feeders 61 can be sleeved together through a heat-shrinkable sleeve, and a general label 65 of the bundled jumper is provided on the heat-shrinkable sleeve 64 .
