[0002] With the continuous development of mobile communication technologies and the continuous innovation of antenna technologies, the size of antennas has become larger and larger, and the wind resistance of antennas has also become larger and larger. Currently, the size of the windward surface of some antennas has reached 500mm×2700mm, and the wind resistance of the antennas poses a huge challenge to the structural installation parts and the safety of the iron tower.

[0003] The reduction of the wind resistance of the radome mainly includes: reducing the wind resistance of the windward surface by reducing the pressure difference resistance between the windward surface and the leeward surface of the radome. Currently, the main technical means used to reduce this pressure difference resistance are: 1. reducing the windward area; 2. designing the shape of the radome, such as increasing rounded corners or groove structures, etc. However, the windward area and the rounded corners of the radome are limited by the overall space size of the machine, and it is impossible to achieve a large-scale optimization and adjustment.

Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0044] An embodiment of the present application provides a radome for accommodating an antenna body, and the antenna body includes components for realizing antenna functions. As Figure 1 shown, the radome 1 is fixedly connected to the pole 3 through the radome mounting assembly 2. The radome mounting assembly 2 fixedly connects the radome 1 to the pole 3 on the leeward side 11 of the radome 1. Specifically, the radome mounting assembly 2 and the radome 1 can be movably connected by bolts, or can be fixedly connected by means such as bonding or welding. It can be understood that they can also be connected by other means as long as the radome mounting assembly 2 and the radome 1 can be firmly connected. Specifically, it is not limited here. The radome mounting assembly 2 and the pole 3 can also be movably connected by bolts. It can be understood that the radome mounting assembly can also fixedly connect the radome 1 to the pole 3 on the top surface of the radome 1. It should be noted that Figure 1 only the overall structure of the radome 1 is schematically shown, and the specific structure of the outer surface is not shown.

[0045] Please refer to Figure 2 and Figure 3 together. The radome 1 includes a cover body 1a. The outer surface of the cover body 1a includes an oncoming wind surface 12 and a leeward side 11 that are oppositely arranged. The oncoming wind surface 12 can be used as the radiation surface of the antenna; the leeward side 11 can be used as the mounting surface for fixedly connecting with the radome mounting assembly 2. The oncoming wind surface 12 and the leeward side 11 are both planes for example. Of course, in actual applications, on the premise of not affecting the benefit of reducing wind resistance, the oncoming wind surface 12 and the leeward side 11 can also adopt surfaces of any other shape.

[0046] The outer surface of the cover main body 1a further includes a first wave surface 13 and a second wave surface 14 which are connected between the windward surface 12 and the leeward surface 11 and are oppositely arranged. The first wave surface 13 and the second wave surface 14 are used to reduce the wind resistance of the windward surface 12 and the leeward surface 11. In this embodiment, by making both side surfaces connected between the windward surface 12 and the leeward surface 11 be wave surfaces, that is, the first wave surface 13 and the second wave surface 14, compared with the prior art methods such as adding rounded corners or groove structures, this embodiment designs the overall shape of the side surface of the radome, and without excessively increasing the overall space size of the machine, it can achieve a significant optimization and adjustment of the wind resistance of the windward surface 12 and the leeward surface 11, so that a larger wind resistance benefit can be obtained.

[0047] In addition, in order to form a closed internal space of the cover main body 1a, the outer surface of the cover main body 1a further includes a first end surface and a second end surface which are oppositely arranged. The above-mentioned windward surface 12, leeward surface 11, first wave surface 13 and second wave surface 14 enclose a cover body with openings at both ends, and the first end surface and the second end surface are used to close the openings at both ends of the cover body. The first end surface and the second end surface are both flat surfaces for example. Of course, in practical applications, without affecting the wind resistance reduction benefit, the first end surface and the second end surface can also adopt other arbitrarily shaped surfaces. That is to say, the overall contour shape of the outer surface of the cover main body 1a is a hexahedron, such as Figure 1 the radome 1 shown in

[0048] In some embodiments, the cover main body 1a has a specified center line A located in the middle of the first wave surface 13 and the second wave surface 14. This center line A is, for example, the symmetry axis of the first wave surface 13 and the second wave surface 14 (as Figure 2 shown) or the center line A passing through the symmetry center O of the first wave surface 13 and the second wave surface 14 (as Figure 3 shown). When the windward surface 12 is a flat surface, this center line A can also be perpendicular to the windward surface 12 and pass through the center of the windward surface 12.

[0049] On this basis, as Figure 2 and Figure 3As shown, the first wave surface 13 includes a first arc surface 131 and a second arc surface 132. The distance D1 between the first arc surface 131 and the center line A increases from two boundaries in the direction parallel to the center line A to a position between the two boundaries. This position is, for example, the middle position between the two boundaries, or it can be a position deviating from the middle position and closer to any one of the boundaries. That is, the above-mentioned distance D1 is the maximum value at the middle position between the two boundaries of the first arc surface 131 or at a position closer to any one of the boundaries, and there is only one such maximum value. The distance D2 between the second arc surface 132 and the center line A monotonically decreases from a boundary close to the first arc surface 131 to the other boundary. That is, the above-mentioned distance D2 is the maximum value at the position of a boundary of the second arc surface 132 close to the first arc surface 131, and is the minimum value at the position of the other boundary. It is easy to understand that the above-mentioned distances D1 and D2 are only adaptively marked at a certain position.

[0050] And / or, the second wave surface 14 includes a third arc surface 141 and a fourth arc surface 142. The distance D3 between the third arc surface 141 and the center line A increases from two boundaries in the direction parallel to the center line A to a position between the two boundaries. This position is, for example, the middle position between the two boundaries, or it can be a position deviating from the middle position and closer to any one of the boundaries. That is, the above-mentioned distance D3 is the maximum value at the middle position between the two boundaries of the third arc surface 141 or at a position closer to any one of the boundaries, and there is only one such maximum value. The distance D4 between the fourth arc surface 142 and the center line A monotonically decreases from a boundary close to the third arc surface 141 to the other boundary. That is, the above-mentioned distance D4 is the maximum value at the position of a boundary of the fourth arc surface 142 close to the third arc surface 141, and is the minimum value at the position of the other boundary. It is easy to understand that the above-mentioned distances D3 and D4 are only adaptively marked at a certain position.

[0051] In this way, the above-mentioned first arc surface 131 and second arc surface 132 can jointly form a wavy streamline side surface. Similarly, the third arc surface 141 and fourth arc surface 142 can jointly form a wavy streamline side surface. When the air flow passes through the first arc surface 131 or the third arc surface 141, or passes through the first arc surface 131 and the third arc surface 141, it can move the separation point of the air flow from the side surface of the radome backward, thereby reducing the wake region (that is, the region between the air flow and the side surface after the air flow separates from the side surface of the radome 1). The negative pressure region of the leeward surface 11 will decrease with the reduction of the wake region, thereby reducing the pressure difference resistance between the windward surface 12 and the leeward surface 11, and further reducing the wind resistance of the windward surface 12. Moreover, the wind resistance of both the windward surface 12 and the leeward surface 11 can be reduced simultaneously, thereby obtaining a greater wind resistance benefit.

[0052] In the existing solutions, such asFigure 5 As shown, the side of the radome is a plane, and there is a rounded corner between the windward side and the side. The separation point between the side of the existing solution and the airflow is at position E1, and the wake region is in region F1. As Figure 6 shown, the separation point between the wavy streamline side adopted in this embodiment and the airflow is at position E2, which is significantly shifted backward relative to Figure 5 position E1, and the wake region is in region F2, which is significantly reduced relative to Figure 5 region F1, so that the negative pressure region can be greatly reduced, and thus the pressure difference resistance on the front of the radome can be reduced, and a greater wind resistance benefit can be obtained.

[0053] In one embodiment, the two sides where the windward side 12 is respectively connected to the first wave surface 13 and the second wave surface 14 are the first side ([[]]END]] Figure 2 and Figure 3 the left side in [[[]]END]] Figure 2 and Figure 3 ), and the second side ([[]]END]] Figure 2 and Figure 3 the right side in [[[]]END]] Figure 2 and Figure 3 ), and the two sides where the leeward side 11 is respectively connected to the first wave surface 13 and the second wave surface 14 are the third side ([[]]END]] Figure 2 and Figure 3 the left side in [[[]]END]] Figure 2 and Figure 3 ), and the fourth side ([[]]END]] Figure 2 and Figure 3 the right side in [[[]]END]] Figure 2 shown, the first arc surface 131 is adjacent to the first side, and the second arc surface 132 is adjacent to the third side; the third arc surface 141 is adjacent to the second side, and the fourth arc surface 142 is adjacent to the fourth side. In this case, the airflow can flow through the first arc surface 131 and the third arc surface 141 located on both sides of the windward side 12, so that the separation points of the two branch flows of the airflow after being split by the windward side 12 from the first arc surface 131 and the third arc surface 141 can be shifted backward, so that the pressure difference resistance between the windward side 12 and the leeward side 11 can be greatly reduced, and further the wind resistance of the windward side 12 can be reduced. Moreover, the wind resistance of both the windward side 12 and the leeward side 11 can be reduced simultaneously, so that a greater wind resistance benefit can be obtained. Further, the first arc surface 131 and the third arc surface 141 can be symmetric with respect to the center line A; and / or, the second arc surface 132 and the fourth arc surface 142 can be symmetric with respect to the center line A. In this way, the above-mentioned first wave surface 13 and the second wave surface 14 are axisymmetric structures on both sides of the windward side 12 and the leeward side 11, so that the airflow distribution on both sides of the windward side 12 and the leeward side 11 can be ensured to be consistent, and further it is beneficial to reduce the wake region.

[0054] In another embodiment, as Figure 3As shown, the first arcuate surface 131 can also be adjacent to the first side, and the second arcuate surface 132 can be adjacent to the third side; the third arcuate surface 141 can be adjacent to the fourth side, and the fourth arcuate surface 142 can be adjacent to the second side. Of course, in practical applications, the first arcuate surface 131 can also be adjacent to the third side, and the second arcuate surface 132 can be adjacent to the first side; the third arcuate surface 141 can be adjacent to the second side, and the fourth arcuate surface 142 can be adjacent to the fourth side. That is to say, when the first arcuate surface 131 is adjacent to the windward surface 12, the third arcuate surface 141 is adjacent to the leeward surface 11; when the first arcuate surface 131 is adjacent to the leeward surface 11, the third arcuate surface 141 is adjacent to the windward surface 12. When the second arcuate surface 132 is adjacent to the windward surface 12, the fourth arcuate surface 142 is adjacent to the leeward surface 11; when the second arcuate surface 132 is adjacent to the leeward surface 11, the fourth arcuate surface 142 is adjacent to the windward surface 12. In this case, the airflow flows through the first arcuate surface 131 and the fourth arcuate surface 142 on both sides of the windward surface 12. The effect of this is that while reducing the wind resistance of the windward surface 12, the wind resistance of the windward surface 12 can be made consistent with the wind resistance of the leeward surface 11, thereby improving the situation where the wind resistance of the leeward surface 11 is greater than that of the windward surface 12 in general cases, and thus reducing max (wind resistance of the windward surface 12, wind resistance of the leeward surface 11), that is, reducing the maximum value between the wind resistance of the leeward surface 11 and the wind resistance of the windward surface 12. Further, the orthographic projections of the first arcuate surface 131 and the third arcuate surface 141 on the cross-section B of the cover body 1a perpendicular to the center line A are symmetric with respect to the center O of the cross-section B. For example, as Figure 3 shown, the cross-section B is located at the middle position between the windward surface 12 and the leeward surface 11. And / or, the orthographic projections of the second arcuate surface 132 and the fourth arcuate surface 142 on the cross-section B of the cover body 1a perpendicular to the center line A are symmetric with respect to the center O of the cross-section B. In this way, the above-mentioned first wavy surface 13 and second wavy surface 14 are centrosymmetric structures with respect to each other on both sides of the windward surface 12 and the leeward surface 11, which is conducive to making the wind resistance of the windward surface 12 consistent with the wind resistance of the leeward surface 11.

[0055] In some embodiments, such as Figure 4As shown, the arc shapes of the first arc surface 131 and the third arc surface 141, as well as the second arc surface 132 and the fourth arc surface 142 in the cross-section parallel to the center line A can satisfy the following parameter conditions to achieve the effect of significantly reducing the wind resistance of the radome. Specifically, taking the arc shapes of the first arc surface 131 and the third arc surface 141 being the same, and the arc shapes of the second arc surface 132 and the fourth arc surface 142 being the same as an example, one boundary of the first arc surface 131 and the third arc surface 141 away from the adjacent windward surface 12 or leeward surface 11 is the first control boundary P1, and the distance between the first control boundary P1 and the adjacent windward surface 12 or leeward surface 11 in the direction parallel to the center line A is the first distance D5; one boundary of the second arc surface 132 and the fourth arc surface 142 away from the adjacent windward surface 12 or leeward surface 11 is the second control boundary P2, and the distance between the second control boundary P2 and the adjacent leeward surface 11 or windward surface 12 in the direction parallel to the center line A is the second distance D6; the first distance D5 and the second distance D6 are equal; the distance between the first control boundary P1 and the center line A is the third distance D7; the distance between the second control boundary and the center line A is the fourth distance D8; the third distance D7 is greater than the fourth distance D8; the included angle between the first arc surface 131 and the third arc surface 141 and the adjacent windward surface 12 or leeward surface 11 is the first diversion angle θ1, and the included angle between the second arc surface 132 and the fourth arc surface 142 and the adjacent windward surface 12 or leeward surface 11 is the second diversion angle θ2; the first diversion angle θ1 is greater than the second diversion angle θ2. The first diversion angle θ1 and the second diversion angle θ2 are defined as the included angle between the tangent line of the arc surface passing through the side of the adjacent windward surface 12 or leeward surface 11 and the windward surface 12 or leeward surface 11.

[0056] In some embodiments, the above first diversion angle θ1 is greater than or equal to 30° and less than or equal to 60°. In practical applications, the specific value of the first diversion angle θ1 can be selected within the above angle range of the first diversion angle θ1 according to specific situations, and on the premise that the above first distance D5 is determined, the above third distance D7 can be determined.

[0057] In some embodiments, both the first distance D5 and the second distance D6 are equal to one-third of the distance D between the windward surface 12 and the leeward surface 11 in the direction parallel to the center line A.

[0058] In some embodiments, such as Figure 4As shown, a first transition surface 133 is connected between a first control boundary P1 of the first arc surface 131 and a second control boundary P2 of the second arc surface 132; and / or, a second transition surface 143 is connected between a first control boundary P1 of the third arc surface 141 and a second control boundary P2 of the fourth arc surface 142. In this way, the first arc surface 131, the first transition surface 133, and the second arc surface 132 can jointly form a wavy streamline side surface. Similarly, the third arc surface 141, the second transition surface 143, and the fourth arc surface 142 can jointly form a wavy streamline side surface. Figure 4 The arc shapes of the first transition surface 133 and the second transition surface 143 in a cross-section parallel to the center line A are the same. Of course, in practical applications, the arc shapes of the first transition surface 133 and the second transition surface 143 in a cross-section parallel to the center line A can also be different.

[0059] In some embodiments, as Figure 2 and Figure 3 shown, a first rounded corner 15 is provided between the first arc surface 131 and the third arc surface 141 and the adjacent windward surface 12 or leeward surface 11; a second rounded corner 16 is provided between the second arc surface 132 and the fourth arc surface 142 and the adjacent windward surface 12 or leeward surface 11. Both the first rounded corner 15 and the second rounded corner 16 are used to achieve arc transition between the windward surface 12 or leeward surface 11 and the adjacent arc surface, thereby facilitating wind resistance reduction.

[0060] As another technical solution, as Figure 1 shown, this embodiment further provides an antenna device, including an antenna cover 1, an antenna body disposed in the antenna cover 1, and an antenna cover mounting assembly 2. The antenna cover mounting assembly 2 is used to fixedly connect the antenna cover 1 to the pole 3, and the antenna cover 1 adopts the above-mentioned antenna cover 1 provided in this embodiment.

[0061] For the antenna device provided in this embodiment, by adopting the above-mentioned antenna cover 1 provided in this embodiment, the purpose of significantly reducing the wind resistance of the windward surface 12 and the leeward surface 11 can be achieved. Compared with the existing technologies such as adding rounded corners or groove structures, without significantly increasing the overall machine space size, significant optimization and adjustment can be realized, thereby obtaining a greater wind resistance benefit.

[0062] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present application. However, the present application is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present application, and these modifications and improvements are also regarded as the protection scope of the present application.
