Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to a antenna cover. Background Art

[0002] The radome is an electromagnetic transparent window that ensures the normal operation of the radar antenna. It is also called an electromagnetic window. It is a structure that protects the antenna system from the influence of the external environment.

[0003] Patent document announcement number CN212542687U discloses an antenna cover. A flange is provided at the bottom of the cover body. The flange and the cover body are integrally formed, which can be easily installed. However, in actual use, the use environment of the antenna will affect the actual service life of the cover body. When in the external environment, if a hard object hits the cover, such as a falling object falling from a height, there is a risk of the cover breaking, thereby affecting the protective performance of the cover. Utility Model Content

[0004] In order to solve the problems of the prior art, the utility model provides an antenna cover, comprising: a shield, wherein at least two connecting plates near the bottom are arranged on the side wall of the shield for connecting with the antenna assembly;

[0005] A protective shell, wherein the protective shell is sleeved on the outside of the protective cover, and a distance is left between the protective shell and the protective cover;

[0006] The bottom of the protective shell is rotatably connected to the connecting plate;

[0007] A support column is arranged on the top of the shield, and the support column penetrates the protective shell.

[0008] Furthermore, a plurality of through holes are provided on the surface of the protective shell.

[0009] Furthermore, a plurality of ribs are evenly arranged on the surface of the protective shell, and the ribs are located between adjacent through holes.

[0010] Furthermore, the bottom of the protective shell is in a circular ring structure, and the top of the connecting plate is provided with a sliding groove adapted to the circular ring structure.

[0011] Furthermore, a metal film layer is provided on the surface of the protective shell.

[0012] Furthermore, the thickness of the metal film layer is at least 2 mm.

[0013] Beneficial effects of the utility model:

[0014] The protective shell is provided to protect the shield, and the bottom of the protective shell is movably connected to the connecting plate. Therefore, when a hard object collides with the protective shell, the protective shell can protect the shield from damage. At the same time, at the moment when the object contacts the protective shell, the protective shell rotates under the impact force of the external object, thereby achieving a force unloading effect, thereby reducing the damage to the protective shell caused by the object.

[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] See also Figures 1 to 4 , a radome, comprising: a shield 1, wherein at least two connecting plates 3 are provided on the side wall of the shield 1 near the bottom, for connecting with an antenna assembly;

[0023] A protective shell 2, wherein the protective shell 2 is sleeved on the outside of the protective cover 1, and a distance is left between the protective shell 2 and the protective cover 1;

[0024] The bottom of the protective shell 2 is rotatably connected to the connecting plate 3;

[0025] A support column 6 is disposed on the top of the shield 1 , and the support column 6 penetrates the protective shell 2 .

[0026] Among them, the main invention point of the present application is that the protective cover is protected by a protective shell, so as to avoid the problem of objects hitting the protective cover, and the bottom of the protective shell is rotatably connected to the connecting plate, so that when the object contacts the protective shell, the protective shell rotates, thereby unloading the force, effectively reducing the damage to the protective shell by the object.

[0027] Furthermore, a plurality of through holes 4 are provided on the surface of the protective shell 2 .

[0028] Among them, the function of the through hole is to increase the fluidity between the shield and the protective shell, thereby increasing the heat dissipation effect of the antenna assembly in a high temperature environment. At the same time, it can reduce the weight of the protective shell and reduce the bearing capacity of the protective shell of the antenna assembly.

[0029] In actual use, the protective shell can be provided with a metal mesh plate or a metal wire mesh.

[0030] Furthermore, a plurality of ribs 5 are evenly arranged on the surface of the protective shell 2 , and the ribs 5 are located between adjacent through holes 4 .

[0031] The function of the ribs is to increase the strength of the protective shell and, at the same time, to improve the rotation triggering force of the protective shell. For example, when the wind is strong enough, the ribs can increase the contact area between the wind and the protective shell, thereby enabling the protective shell to start more quickly.

[0032] Furthermore, the bottom of the protective shell 2 is in a circular ring structure, and the top of the connecting plate 3 is provided with a sliding groove adapted to the circular ring structure.

[0033] The circular ring reduces the friction between the protective shell and the connecting plate, thereby improving the rotation effect of the protective shell.

[0034] Furthermore, a metal film layer is provided on the surface of the protective shell 2 , and the surface of the metal film layer is coated with electromagnetic powder, and the thickness of the metal film layer is at least 2 mm.

[0035] Among them, the metal film layer can reflect light to a high degree and has good heat insulation, so the temperature of the antenna is less affected by the external environment when it is working.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
