Description

Technical Field

[0001] The present invention relates to the technical field of mobile communications, and particularly to an antenna top cover, a top cover assembly and an antenna. Background Art

[0002] With the development of communication technologies, antennas need to support more and more frequency bands. In traditional antenna designs, the ports of each frequency band are usually arranged on the bottom cover of the antenna, and a certain distance should be maintained between each port to facilitate the client to connect with the corresponding connector and wrap waterproof tape.

[0003] However, with the increase in frequency bands, the layout of the connectors on the bottom cover has become too dense, and it has even been impossible to layout the connectors on the bottom cover, which has become a technical bottleneck restricting the further integration of more frequency bands in the antenna. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that in the prior art, the layout of the connectors on the bottom cover of a multi-band antenna is too dense, and it has even been impossible to layout the connectors on the bottom cover, on the premise of ensuring the waterproof performance of the antenna outdoors.

[0005] To achieve the purpose of the present invention, the following technical solutions are adopted:

[0006] A first aspect of the present invention provides an antenna top cover for covering the top opening of an antenna cover. The top cover includes a cover body and a first mounting plate. One side edge of the cover body horizontally extends outward to form a first convex plate. The outer edge of the first convex plate perpendicularly extends downward to form a first side frame with a bottom opening and a side opening. The first mounting plate is embedded in the space enclosed by the first side frame to seal the bottom opening of the first side frame. The side opening of the first side frame is used to connect the space enclosed by the first side frame with the internal space of the antenna cover. The first mounting plate is provided with assembly holes for installing feeder connectors, and the assembly holes penetrate through the first mounting plate.

[0007] Further improvement lies in that the first mounting plate is parallel to the first convex plate.

[0008] Further improvement lies in that the outer contour shape and size of the first mounting plate are adapted to the cross-sectional shape and size of the space enclosed by the first side frame.

[0009] Further improvement lies in that the cross-section of the first side frame is generally in a "C" shape.

[0010] A further improvement is that a first glue groove is provided on the outer edge of the bottom surface of the end cover body, a second glue groove is provided at the edge of the side opening of the first side frame, and a third glue groove is provided on the inner edge of the first mounting plate. The first glue groove, the second glue groove and the third glue groove are connected to form a closed-loop glue groove that matches the top cross-section of the antenna cover.

[0011] A further improvement is that the first glue storage groove, the second glue storage groove and the third glue storage groove are filled with silica gel or are installed with sealing strips.

[0012] A further improvement is that a cable clamp is provided on the first mounting plate, and the cable clamp is used to clamp and position the cable connected to the inside of the antenna cover on the feeder connector.

[0013] A further improvement is that a support column is provided on the bottom surface of the first protruding plate, a mounting hole is provided on the support column, a fixing hole is provided on the first mounting plate, and the first mounting plate is embedded in the first side frame and rests on the support column and is fixed by fasteners passing through the fixing hole and the mounting hole in sequence.

[0014] A second aspect of the present invention provides a top end cover assembly, comprising a top end cover as described in any one of the first aspects, wherein at least one feeder connector is mounted on a first mounting plate of the top end cover.

[0015] The third aspect of the present invention proposes an antenna, comprising an antenna cover, a top cover assembly covering the top of the antenna cover, a bottom cover assembly covering the lower end of the antenna cover, and an antenna body installed inside the antenna cover, the top cover assembly adopts a top cover assembly described in the second aspect, a first incision is opened on the upper end of a corresponding side plate on the antenna cover, and the space enclosed by the first side frame is connected to the internal space of the antenna cover through a side opening and the first incision.

[0016] The beneficial effects of the present invention are:

[0017] The present invention improves the top cover structure of the radome and then arranges additional feeder connectors on the top cover of the radome, thereby effectively supporting more frequency bands and solving the problem of too dense feeder connectors on the bottom cover, meeting the requirements of modern communication systems for multiple frequency bands, improving space utilization, and making the antenna design more compact and efficient.

[0018] Since the space formed between the first protruding plate and the first side frame protrudes outside the antenna cover, there is more sufficient space to reasonably arrange the feeder connector. The first mounting plate is embedded in the space enclosed by the first side frame. Therefore, the enclosed space can provide wiring space for the cables of the feeder connector on the first mounting plate. At the same time, the first protruding plate and the first side frame can shield rainwater, preventing rainwater from directly hitting the first mounting plate and the feeder connector, thereby achieving the purpose of waterproofing.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Furthermore, when an element is considered to be "transmission-connected" to another element, the two can achieve power transmission, and its specific implementation method can be implemented using the existing technology, which will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only and do not represent the only implementation method.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0030] Please refer to the attached Figure 1 -Attached Figure 5 In a first aspect of an embodiment of the present invention, an antenna top cover is provided, which is used to cover the top opening of the antenna cover 1, such as Figure 1 and Figure 2 As shown, the top cover includes an end cover body 2 and a first mounting plate 3. One side edge of the end cover body 2 extends horizontally outward to form a first convex plate 4. The outer edge of the first convex plate 4 extends downward perpendicularly to the first convex plate 4 to form a first side frame 5 with a bottom opening and a side opening. The first mounting plate 3 is embedded in the space formed by the first side frame 5 to seal the bottom opening of the first side frame 5. The side opening of the first side frame 5 is used to achieve communication between the space formed by the first side frame 5 and the internal space of the antenna cover 1. The first mounting plate 3 is provided with an assembly hole 7 for mounting a feeder connector 6. The assembly hole 7 passes through the first mounting plate 3. In this embodiment, the number of the assembly holes 7 is four, and the four assembly holes 7 are distributed on the first mounting plate 3. In addition, those skilled in the art can set the number of the assembly holes 7 according to actual needs, and this embodiment does not make a specific limitation.

[0031] It can be understood that by improving the top cover structure of the radome 1 and then arranging additional feeder connectors 6 on the top cover of the radome 1, the present invention solves the problem of overcrowded feeder connectors 6 on the bottom cover while effectively supporting more frequency bands, meets the requirements of modern communication systems for multiple frequency bands, improves space utilization, and makes the antenna design more compact and efficient.

[0032] In addition, since the space formed between the first convex plate 4 and the first side frame 5 protrudes outside the radome 1, there is more sufficient space to reasonably arrange the feeder connectors 6. The first mounting plate 3 is embedded in the space surrounded by the first side frame 5. Therefore, the surrounded space can provide wiring space for the cables of the feeder connectors 6 on the first mounting plate 3. At the same time, the first convex plate 4 and the first side frame 5 can play a role in shielding rainwater, preventing rainwater from directly hitting the first mounting plate 3 and the feeder connectors 6, thus achieving the purpose of waterproofing.

[0033] Preferably, the end cover body 2, the first convex plate 4, and the first side frame 5 are integrally formed.

[0034] Specifically, in this embodiment, the first mounting plate 3 is parallel to the first convex plate 4, and the outer contour shape and size of the first mounting plate 3 are adapted to the cross-sectional shape and size of the space surrounded by the first side frame 5. As Figure 3 shown, in this embodiment, the cross-section of the first side frame 5 is generally in a "C" shape.

[0035] It can be understood that since the outer contour shape and size of the first mounting plate 3 are adapted to the cross-sectional shape and size of the space surrounded by the first side frame 5, when the first mounting plate 3 is embedded in the first side frame 5, the side edges of the first mounting plate 3 are in contact with the inner wall of the first side frame 5.

[0036] In this embodiment, as Figure 3 and Figure 4 shown, a first glue storage groove 8 is provided at the outer edge of the bottom surface of the end cover body 2, and second glue storage grooves 9 are provided at the opening edges of one side of the first side frame 5 (that is, second glue storage grooves 9 are provided at the edges of the two side plates of the first side frame 5). A third glue storage groove 10 is provided at the inner edge of the first mounting plate 3. The first glue storage groove 8, the second glue storage grooves 9, and the third glue storage groove 10 are connected to form a closed-loop glue storage groove that matches the top cross-section of the radome 1. Silicone (not shown in the figure) or a sealing strip (not shown in the figure) is filled in the first glue storage groove 8, the second glue storage grooves 9, and the third glue storage groove 10.

[0037] It can be understood that since the first glue storage groove 8, the second glue storage groove 9, and the third glue storage groove 10 are connected to form a closed-loop glue storage groove that matches the top cross-section of the antenna cover 1, when the top cover is covered on the top opening of the antenna cover 1, the top surface of the antenna cover 1 can be completely embedded in the closed-loop glue storage groove and abut against the sealing strip in the glue storage groove for dust and water prevention, thereby improving the sealing performance.

[0038] In a preferred solution of the present embodiment, a cable clamp 11 is provided on the first mounting plate 3 , and the cable clamp 11 is used to clamp and position the cable on the feeder connector 6 connected to the inside of the antenna cover 1 .

[0039] It can be understood that the number of the cable clamps 11 corresponds one to one to the number of the feeder connectors 6. The fixing effect of the cable clamps 11 can ensure that each cable is routed along a predetermined path. The cable clamps 11 can help arrange multiple cables neatly together to avoid entanglement and confusion between the cables, making the internal space of the antenna tidier.

[0040] In this embodiment, a support column 12 is provided on the bottom surface of the first protruding plate 4, and a mounting hole 13 is provided on the support column 12. A fixing hole 14 is provided on the first mounting plate 3. After the first mounting plate 3 is embedded in the first side frame 5, it rests on the support column 12 and is fixed by fasteners 15 that pass through the fixing hole 14 and the mounting hole 13 in sequence. Specifically, the fasteners 15 are bolts.

[0041] It can be understood that by setting a support column 12 on the bottom surface of the first protruding plate 4, and setting a mounting hole 13 and a fixing hole 14 on the support column 12 and the first mounting plate 3 respectively, the first mounting plate 3 can be firmly embedded in the first side frame 5 and fastened to the support column 12 to form a whole with the top end cover.

[0042] A second aspect of an embodiment of the present invention proposes a top end cover assembly, comprising a top end cover as described in any one of the first aspect of the embodiment, wherein at least one feeder connector 6 is installed on the first mounting plate 3 of the top end cover. In this embodiment, four feeder connectors 6 are installed on the first mounting plate 3 of the top end cover.

[0043] A third aspect of an embodiment of the present invention provides an antenna, such as Figure 1 and Figure 2As shown, it includes an antenna cover 1, a top cover assembly covering the top of the antenna cover 1, a bottom cover assembly 16 covering the lower end of the antenna cover 1, and an antenna body (not shown in the figure) installed inside the antenna cover 1, the top cover assembly adopts a top cover assembly described in the second aspect of the embodiment, and a first incision 17 is opened on the upper end of a corresponding side plate of the antenna cover 1, and the shape and size of the first incision 17 are adapted to the shape and size of a side opening of the first side frame 5, and the space enclosed by the first side frame 5 is connected to the internal space of the antenna cover 1 through a side opening and the first incision 17.

[0044] In a preferred scheme of the present embodiment, the other two side edges of the end cover body 2 can also extend horizontally outward to form a second convex plate and a third convex plate (not shown in the figure), the outer edge of the second convex plate extends downward perpendicularly to the second convex plate to form a second side frame (not shown in the figure) with a bottom opening and a side opening, and the space surrounded by the second side frame has a second mounting plate (not shown in the figure) embedded in it; the outer edge of the third convex plate extends downward perpendicularly to the third convex plate to form a third side frame (not shown in the figure) with a bottom opening and a side opening, and the space surrounded by the third side frame has a third mounting plate (not shown in the figure) embedded in it, and at the same time, a second incision and a third incision (not shown in the figure) are opened on the upper ends of the corresponding side plates of the antenna cover 1, so that more feeder connectors 6 can be arranged on the top cover of the antenna and the purpose of waterproofing can be achieved. Since its structure is similar to the structure formed by the first convex plate 4, the first side frame 5, the first mounting plate 3, and the first incision 17, it will not be repeated in this embodiment.

[0045] As is well known in the art, the antenna body is mainly composed of a reflector and functional components such as an antenna array and a feeding network arranged on the reflector. Since the specific structure of the antenna body does not belong to the improvement of the present invention, it is not described in detail in this embodiment.

[0046] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-mentioned embodiments only express the specific implementation of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
