Description

Technical Field

[0001] This utility model relates to the field of wireless communication, and in particular to a tetrahedral reflector radome. Background Technology

[0002] Corner reflectors, typically referring to radar corner reflectors, are electromagnetic wave reflecting devices composed of mutually perpendicular metal mirror planes. They generally reflect incident electromagnetic waves back in their original incident direction. A tetrahedral corner reflector consists of four mutually perpendicular metal planes. When used outdoors, corner reflectors are susceptible to erosion from wind, sand, rain, and snow. The accumulation of sand and snow inside the corner reflector can affect its performance. Utility Model Content

[0003] To overcome the problems in the prior art, ensure that the tetrahedral reflector can work in various harsh environments such as wind, sand, rain, and snow, prevent sand and snow from accumulating inside the reflector, and extend the service life of the reflector, this utility model provides a tetrahedral reflector radome that can be quickly installed and disassembled. It has a fiberglass foam sandwich structure and has excellent wave transmission performance.

[0004] The technical solution of this utility model is:

[0005] A tetrahedral reflector radome, characterized in that it comprises a radome body composed of a four-sided conical structure and a fixing buckle;

[0006] The radome consists of a hollow tetrahedral body and a quadrangular prism face at the opening of the tetrahedral body; the dimensions of the tetrahedral body match the dimensions of the four metal planes of the tetrahedral corner reflector, and when the radome is fitted onto the tetrahedral corner reflector, the inner surface of the tetrahedral body fits into the four metal planes of the tetrahedral corner reflector.

[0007] The quadrangular prism has elongated holes for passing through the fixing buckles; when the antenna cover is fitted onto the tetrahedral reflector, the elongated holes are aligned with the elongated holes on the L-shaped connectors at the bottom edge of the tetrahedral reflector.

[0008] The fixing buckle passes through the elongated hole and the elongated opening to fix the antenna cover to the tetrahedral reflector.

[0009] Furthermore, the fixing buckle has an L-shaped structure, with its short side outer end connected to a semi-circular limiting piece; the diameter of the semi-circular limiting piece is greater than the width of the elongated hole and less than the length of the elongated hole.

[0010] Furthermore, the cover is a foam fiberglass sandwich structure; the middle part is a foam structure, and both sides are wrapped with fiberglass cloth.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The tetrahedral corner reflector radome of this utility model has a fiberglass foam sandwich structure, possessing excellent electrical properties, corrosion resistance, and wave transmission performance. It can prevent erosion from harsh environments such as wind, sand, rain, and snow, while not affecting the normal use of the corner reflector.

[0013] 2. The tetrahedral corner reflector radome of this utility model has a four-sided pyramid structure. Sand, dust, rain and snow will fall directly off the radome and avoid accumulating inside the corner reflector, thus not affecting the use of the corner reflector. At the same time, its structure is simple and highly practical.

[0014] 3. The tetrahedral reflector radome and the tetrahedral reflector described in this utility model are connected by snap-fit, which allows for quick installation and disassembly. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0022] In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0023] like Figure 1 As shown, a tetrahedral reflector radome has a tetrahedral conical structure, consisting of a hollow tetrahedral conical body and four prism faces located at the openings of the conical body. Elongated holes are formed on the prism faces. The tetrahedral reflector radome is integrally molded using a die-casting process to fit the tetrahedral reflector. The dimensions of its tetrahedral conical body match the dimensions of the four metal planes of the tetrahedral reflector. When the radome is fitted onto the tetrahedral reflector, the inner surface of the tetrahedral conical body fits snugly against the four metal planes of the tetrahedral reflector, protecting the reflector from external wind, sand, rain, and snow. Furthermore, the radome body 1 is constructed entirely of a glass-reinforced foam sandwich structure. Figure 2 As shown, the middle part is a foam structure 5, wrapped with fiberglass cloth 4 on both sides, possessing excellent electrical properties, corrosion resistance, and wave transmission properties. It can prevent erosion from harsh environments such as wind, sand, rain, and snow, and will not affect the normal use of the corner reflector.

[0024] like Figures 3 to 5 As shown, the tetrahedral reflector radome has elongated holes for the fasteners 2 to pass through on its two opposite mounting edges. The fasteners 2 are L-shaped, with their short outer ends connected to semi-circular limiting pieces. The diameter of the semi-circular limiting pieces is greater than the width of the elongated holes but less than their length. L-shaped connectors 3 are fixed to the bottom edges of the two opposite edges of the tetrahedral reflector, and these connectors 3 have holes. The elongated holes of the tetrahedral reflector radome correspond to the holes on the L-shaped connectors 3 on the bottom edges of the tetrahedral reflector. The tetrahedral reflector radome body 1 is then fastened onto the tetrahedral reflector, ensuring that the elongated holes on the mounting edges of the tetrahedral reflector radome correspond to the L-shaped connectors 3 on the edges of the tetrahedral reflector. Lay the fixing buckle 2 flat so that the semi-circular limiting piece passes through the hole and the elongated hole on the L-shaped connector 3. At this time, the short side of the L-shaped structure of the fixing buckle 2 is just locked in the middle of the elongated hole. Then rotate the buckle. Under the action of gravity, the long side of the L-shaped structure always faces downward. The length of the elongated hole is greater than the diameter of the semi-circular limiting piece of the fixing buckle 2, and the width is less than the diameter of the semi-circular limiting piece of the fixing buckle 2, so the buckle cannot be dislodged. At this time, the tetrahedral reflector antenna cover 1 can be fixed on the tetrahedral reflector.

[0025] The tetrahedral reflector radome 1 is mounted on the tetrahedral reflector. Its special four-sided conical structure is simple and practical. It can prevent sand, dust, rain and snow from accumulating inside the tetrahedral reflector and extend the service life of the corner reflector. At the same time, it adopts a snap-fit ​​connection, which can facilitate quick installation and disassembly.

[0026] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
