DETAILED DESCRIPTION

[0025] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0026] like Figure 1-Figure 4 As shown, the antenna cover provided in this embodiment includes: a cover body 1, a first protrusion 2 and a second protrusion 3 are integrally formed upward on the top surface of the cavity 101 of the cover body 1, and the first protrusion 2 and the second protrusion 3 are spaced apart from each other, and the first protrusion 2 and the second protrusion 3 form a reinforcing rib structure. This structure can improve the rigidity and strength of the top of the cover body 1 without significantly increasing the overall weight.

[0027] The cover body 1 has a plurality of corner surfaces 103 , each of which is provided with a recessed portion 5 . The recessed portion 5 is also formed integrally with the cover body 1 to form an integral structure.

[0028] The top and bottom of the recessed portion 5 extend to the top and side surfaces of the cover body 1, respectively. This design has a certain buffering effect, which can reduce the damage to the corner surface of the radome caused by the impact force when the radome falls. In addition, the top and bottom of the recessed portion 5 extend to the top and side surfaces of the cover body 1, respectively, which can increase the force-bearing area to cope with falls at different angles.

[0029] In this embodiment, the first protrusion 2 and the second protrusion 3 are made with the cover body 1 by an integrated injection molding process to form an integral structure. This design not only improves the structural strength, but also avoids the stress concentration problem that may be caused by the split assembly.

[0030] In this embodiment, the cover body 1 is a polygonal box-shaped structure, taking a square box structure as an example, wherein a cavity 101 therein is connected to an opening 102 on its bottom surface, and is used to accommodate components on the countermeasure host 6 of the drone countermeasure device.

[0031] In this embodiment, multiple corner surfaces 103 of the cover body 1 are all provided with a recessed portion 5. Specifically, the cover body 1 includes four corner surfaces 103, each of which is provided with two recessed portions 5, and the two recessed portions 5 on the same corner surface 103 are symmetrically distributed along the center line.

[0032] The top end of the recessed portion 5 extends to the outside of the second protruding portion 3, and the bottom end of the recessed portion 5 extends to the middle of the outside of the cover body 1, forming a continuous first channel 501. The continuous first channel 501 helps to disperse the impact energy.

[0033] In this embodiment, the first channel 501 has a characteristic that its width is consistent. In other words, from the starting point to the end point of the first channel 501, its width remains unchanged. This design makes the processing of the first channel 501 itself simpler and more convenient.

[0034] In this embodiment, the extension paths of the first protrusion 2 and the second protrusion 3 correspond to the edge contour of the top surface of the cover body 1. That is, the extension paths of the first protrusion 2 and the second protrusion 3 are rectangular, so that the reinforcement effect of the structure covers the entire top of the cover body 1. This design can more effectively disperse stress and improve the overall structural strength while minimizing the weight increase.

[0035] In this embodiment, the first protrusion 2 and the second protrusion 3 are arranged concentrically, and are spaced apart from each other to form a groove 4. The concentrically arranged first protrusion 2 and the second protrusion 3 form a reinforcement structure with uniform and continuous force.

[0036] In this embodiment, the plane profile of the groove 4 corresponds to the top edge profile of the cover body 1, and the vertical section of the groove 4 is stepped. The stepped groove 4 increases the surface area of ​​the antenna cover, which is beneficial to the heat dissipation inside the cover body 1.

[0037] In this embodiment, the first protrusion 2 is disposed in the top center area of ​​the cover body 1 , the second protrusion 3 is disposed in the edge area of ​​the cover body 1 , and the top surface of the first protrusion 2 is higher than the top surface of the second protrusion 3 .

[0038] The height difference between the first protrusion 2 and the second protrusion 3 forms a stepped structure with a high middle and low surroundings at the top of the cavity 101 inside the cover body 1. This structure matches the structural layout of the components on the counter host 6. The components in the middle area are generally higher than those in the edge area, so that the internal space of the antenna cover can be used more reasonably.

[0039] In this embodiment, a drone countermeasure device is also provided, which includes: a countermeasure host 6, the above-mentioned antenna cover is arranged on the top of the countermeasure host 6, and a fixing bracket 7 is arranged at the bottom of the countermeasure host 6.

[0040] In this embodiment, the fixing bracket 7 includes: a supporting horizontal plate 8 and a supporting vertical plate 9 arranged at opposite ends of the supporting horizontal plate 8. Specifically, the supporting horizontal plate 8 has two ends, namely a left end and a right end, and the supporting vertical plate 9 is arranged above the two ends of the supporting horizontal plate 8.

[0041] The support vertical plates 9 are respectively connected to the opposite sides of the counter host 6. The "opposite sides" here refer to the left side and the right side of the counter host 6. The specific installation method is as follows:

[0042] Taking two supporting vertical plates 9 as an example, the bottom end of one supporting vertical plate 9 is fixed to the left end of the supporting horizontal plate 8, and the top end thereof is connected to the left side of the counter host 6; the bottom end of the other supporting vertical plate 9 is fixed to the right end of the supporting horizontal plate 8, and the top end thereof is connected to the right side of the counter host 6. This design ensures stable left and right side support of the counter host 6.

[0043] In this embodiment, the support vertical plate 9 includes: a first connecting plate 901 and a second connecting plate 902 connected to each other and forming an obtuse angle. The first connecting plate 901 located at the top is connected to the counter host 6; the second connecting plate 902 located at the bottom is connected to the support horizontal plate 8.

[0044] The obtuse angle formed by the first connecting plate 901 and the second connecting plate 902 is oriented toward the counter host 6 , so that the supporting vertical plate 9 can maintain good supporting stability without occupying a large space outward.

[0045] In this embodiment, the side surfaces of the first connecting plate 901 and the second connecting plate 902 are respectively penetrated by second channels 10. The second channels 10 specifically include: a plurality of first triangular channels 1001 penetrating the left and right side surfaces of the first connecting plate 901, and second triangular channels 1002 penetrating the front and rear side surfaces of the second connecting plate 902. Such a design can achieve lightweight while maintaining structural integrity.

[0046] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
