Description

Technical Field

[0001] The utility model relates to the technical field of base station antenna covers, in particular to a hot pressing formed antenna cover. Background Art

[0002] A radome protects the antenna system from external environmental influences. It provides excellent electrical penetration of electromagnetic waves and mechanical resistance to harsh external environments. Outdoor antennas are typically placed outdoors, exposed to natural elements such as storms, snow, dust, and solar radiation. These can reduce antenna accuracy, shorten lifespan, and reduce reliability.

[0003] Most existing base station antenna covers are formed by injection molding or extrusion, which has insufficient processing efficiency and high consumable material costs. In addition, the resulting antenna covers are heavy and dense, which is not conducive to the antenna cover's wave transmission effect and improvement of dielectric loss, and has an adverse effect on electrical performance. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a thermoformed antenna cover.

[0009] Preferably, the bottom ends of the long side panels and the short side panels are both provided with edge positioning slots.

[0010] Preferably, the thickness of the foamed composite fiberboard is 2-5 mm.

[0011] Preferably, the foamed composite fiber board comprises an upper fiber panel layer, a resin-based composite foam layer and a lower fiber panel layer which are laminated in sequence from top to bottom.

[0012] The beneficial effects of the present invention are as follows: the hot-pressed antenna cover of the present invention uses a cover body formed by hot-pressing a foamed composite fiberboard, which is quick and convenient to process and has lower processing costs. The foamed composite fiberboard is light in weight and low in density, which is conducive to promoting the wave transmission effect of the antenna cover, reducing dielectric loss, and effectively improving the electrical performance of the antenna cover; the hot-pressed cover body has a smooth transition between the top plate and the long side plates, and between the top plate and the short side plates, and between the adjacent long side plates and short side plates, which is conducive to reducing stress concentration in the cover body and avoiding stress concentration caused by hot-pressed sharp corners / right angles during the cooling process, which may cause the cover body to crack or deform and affect the overall structural strength and life.

DETAILED DESCRIPTION

[0017] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0018] like Figure 1-3 As shown, a hot-pressed antenna cover includes a cover body 1, which is hot-pressed from a foamed composite fiberboard. The cover body 1 includes a top plate 11, two long side plates 12 connected to both sides of the top plate 11, and two short side plates 13 connected to both ends of the top plate 11. There is a smooth transition between the top plate 11 and the long side plates 12, and between the top plate 11 and the short side plates 13. There is a smooth transition between adjacent long side plates 12 and short side plates 13. The top plate 11 is provided with a plurality of first mounting through holes 2.

[0019] This thermoformed radome utilizes a radome body 1 thermoformed from a foamed composite fiberboard, which is quick, convenient, and cost-effective to manufacture. The lightweight and low-density foamed composite fiberboard facilitates wave transmission, reduces dielectric loss, and effectively improves the radome's electrical performance. The thermoformed radome body 1 features smooth transitions between the top panel 11 and long side panels 12, between the top panel 11 and short side panels 13, and between adjacent long and short side panels 12, 13. This helps reduce stress concentration in the radome body 1 and prevents cracking or deformation of the radome body 1 during cooling due to stress concentration caused by hot-pressed sharp or right angles, which can affect overall structural strength and lifespan. The top panel 11 of the radome body 1 is provided with a plurality of first mounting holes 2, allowing the thermoformed radome to be mounted on corresponding base station antenna equipment via bolts, screws, or other fasteners.

[0020] Furthermore, a second mounting hole 3 is provided between the top plate 11 and the long side plate 12, and a third mounting hole 4 is provided between the top plate 11 and the short side plate 13, so that the hot-pressed antenna cover can be installed on the corresponding base station antenna equipment through the second mounting hole 3 and the third mounting hole 4 with the help of bolts / screws and other fasteners, thereby further strengthening the connection between the hot-pressed antenna cover and the base station antenna equipment and improving the stability of the connection between the hot-pressed antenna cover and the base station antenna equipment.

[0021] Furthermore, the inner surface of the top plate 11 is provided with a plurality of crisscross reinforcing ribs 5, which are beneficial to improving the strength of the top plate 11 without increasing the wall thickness, thereby saving material usage, reducing weight, promoting the wave transmission effect of the antenna cover, reducing dielectric loss, and effectively improving the electrical performance of the antenna cover.

[0022] Furthermore, the inner surface of the top plate 11 is also provided with a plurality of reinforcing guide columns 6 which are connected one-to-one with the first mounting through holes 2. The reinforcing guide columns 6 are fixedly connected to at least two reinforcing ribs 5, which is beneficial to strengthening the strength around the first mounting through hole 2, and preventing the thin wall around the first mounting through hole 2 from being easily broken due to stress after the hot-pressed antenna cover is installed on the base station antenna equipment.

[0023] Furthermore, the bottom ends of the long side panels 12 and the short side panels 13 are both provided with edge positioning slots 7. When the hot-pressed antenna cover is installed on the corresponding base station antenna equipment, the base station antenna equipment is correspondingly provided with a latching protrusion for engaging with the edge positioning slots 7. With the help of the edge positioning slots 7, the cover can be positioned more quickly on the base station antenna equipment.

[0024] Furthermore, the thickness of the foamed composite fiber board is 2-5 mm. Preferably, the thickness of the foamed composite fiber board is 3 mm.

[0025] Furthermore, the foamed composite fiberboard comprises an upper fiber panel layer 8, a resin-based composite foam layer 9, and a lower fiber panel layer 10, laminated sequentially from top to bottom. This not only helps reduce the density and lightweight of the cover body 1, but also helps improve the electrical performance of the thermoformed radome. This foamed composite fiberboard is prior art and is only used herein as an application. For example, a foamed composite fiberboard can be obtained by using the invention of a novel composite fiber board and its preparation method disclosed in Publication No. CN111391435A.

[0026] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the scope of protection of the present invention.
