[0041] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] The feeding assembly 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0043] Reference Figure 1-Figure 12 According to the first aspect of the present invention, the feeding assembly 10 is used in the antenna 100. The feeding assembly 10 includes: a metal strip line 1 and a feeding structure 2. The metal strip line 1 includes a conductive portion 11 and a first coupling portion 12. The conductive portion 11 extends along a first direction (refer to the e1 direction in the accompanying drawings). The first coupling portion 12 is connected to one end of the conductive portion 11 in the first direction.

[0044] The feeding structure 2 includes a feeding portion 21 and a second coupling portion 22, the feeding portion 21 extends along a second direction (refer to the e2 direction in the figure), and the second coupling portion 22 is connected to one end of the feeding portion 21 in the second direction. For example, the radiating unit 70 can be connected to one end of the feeding portion 21 away from the second coupling portion 22. For example, the feeding portion 21 can be a feeding balun.

[0045] The second coupling portion 22 and the first coupling portion 12 are abutted against each other in at least two intersecting directions; wherein the first direction intersects with the second direction, for example, the first direction may be perpendicular to the second direction. For example, the at least two intersecting directions may be two directions, the two directions intersect; the at least two intersecting directions may also be three directions, the three directions intersect with each other; for example, the at least two intersecting directions may include one of the first direction and the second direction, and the at least two intersecting directions may also include two of the first direction and the second direction.

[0046] It should be understood that the feeding assembly 10 in this article is applied to the antenna 100. When the power supply of the antenna 100 is direct current, the first coupling part 12 and the second coupling part 22 are in contact electrical connection when they are abutted and matched; when the power supply of the antenna 100 is alternating current, the first coupling part 12 and the second coupling part 22 can be in contact electrical connection when they are abutted and matched, or they can be in non-contact electrical connection when they are abutted and matched; when the first coupling part 12 and the second coupling part 22 are in non-contact electrical connection, an insulating layer can be provided on the surface of at least one of the first coupling part 12 and the second coupling part 22, so that the first coupling part 12 and the second coupling part 22 can be in non-contact electrical connection. By coating the insulating layer on the surface of the first coupling part 12 and the surface of the second coupling part 22, the risk of leakage between the feeding assembly 10 and other components in the antenna 100 can be effectively reduced, and the reliability of the antenna 100 can be improved.

[0047] Reference Figure 6 The standing wave ratio of the antenna 100 using the above-mentioned feeding assembly 10 is between 1.2 and 1.3, which is roughly the same as the standing wave ratio of the relatively fixed feeding part 21 in the traditional soldering connection method, and has almost no effect on the efficiency of the antenna 100. However, by making the second coupling part 22 stop and match with the first coupling part 12 in at least two intersecting directions, when the second coupling part 22 and the first coupling part 12 are loose in one of the stop and match directions, the second coupling part 22 and the first coupling part 12 can still be electrically connected through the tight fit in the remaining stop and match directions, realizing the redundant electrical connection design between the second coupling part 22 and the first coupling part 12 in multiple directions, effectively preventing the first coupling part 12 and the second coupling part 22 from shaking relative to each other, resulting in poor contact between the first coupling part 12 and the second coupling part 22, or causing the gap between the first coupling part 12 and the second coupling part 22 to exceed the feeding transmission distance, so that the first coupling part 12 and the second coupling part 22 are electrically connected reliably, meeting the feeding requirements of the antenna 100.

[0048] Moreover, when assembling the feeding assembly 10, since the second coupling portion 22 and the first coupling portion 12 are stop-fitted in multiple directions and have redundant electrical connection designs in multiple directions, the first coupling portion 12 and the second coupling portion 22 can be electrically connected reliably. Therefore, after the first coupling portion 12 and the second coupling portion 22 are pressed together, it is not necessary to use the traditional soldering connection method to connect and fix the first coupling portion 12 and the second coupling portion 22, and it is not necessary to design a soldering connection process when coupling and connecting the first coupling portion 12 and the second coupling portion 22, so that the production process of the feeding assembly 10 is relatively simple, it is convenient to assemble the feeding assembly 10, and the production efficiency of the feeding assembly 10 is improved.

[0049] When the feeding assembly 10 is inspected and repaired, since the first coupling part 12 and the second coupling part 22 are stop-fitted, rather than relatively fixed in the traditional soldering connection method, the operator can directly separate the first coupling part 12 from the second coupling part 22 without having to perform a tin spot melting operation before separating the first coupling part 12 from the second coupling part 22, which facilitates the disassembly of the first coupling part 12 and the second coupling part 22 and the inspection and repair of the feeding assembly 10.

[0050] According to the feeding assembly 10 of the present invention, by abutting and fitting the first coupling portion 12 and the second coupling portion 22 together in at least two intersecting directions, a redundant electrical connection design between the second coupling portion 22 and the first coupling portion 12 in multiple directions can be realized, so that the first coupling portion 12 and the second coupling portion 22 are electrically connected reliably, and the feeding requirements of the antenna 100 are met. Moreover, it is not necessary to couple the first coupling portion 12 and the second coupling portion 22 together by using a traditional soldering connection method, and it is not necessary to design a soldering connection process when coupling and connecting the first coupling portion 12 and the second coupling portion 22, so that the production process of the feeding assembly 10 is relatively simple, the feeding assembly 10 is easy to disassemble and assemble, and the production efficiency of the feeding assembly 10 is improved; at the same time, this can reduce the number of welding points in the production process of the antenna 100, can effectively reduce the metal pollutants generated by the antenna 100 in the production process, reduce the toxic fumes generated by the antenna 100 in the production process, and effectively protect the life safety of the operators.

[0051] Reference Figure 2-Figure 5 , Figure 8 , Fig.10 , Fig.12 According to some embodiments of the present invention, the first coupling portion 12 has a first abutting structure 123 and a second abutting structure 124, the second coupling portion 22 has a third abutting structure 223 and a fourth abutting structure 224, the first abutting structure 123 abuts against the third abutting structure 223 in the first direction, and the second abutting structure 124 abuts against the fourth abutting structure 224 in a direction intersecting with the first direction. The direction intersecting with the first direction may be the second direction, and the direction intersecting with the first direction may also be the third direction.

[0052] When the first coupling part 12 and the second coupling part 22 are assembled together, at least one of the first direction and the direction intersecting the first direction can intersect with the gravity direction of the first coupling part 12, and at least one of the first direction and the direction intersecting the first direction can intersect with the gravity direction of the second coupling part 22, so that one of the first coupling part 12 and the second coupling part 22 can be pressed against the other in at least one direction, so that the electrical connection between the first coupling part 12 and the second coupling part 22 is reliable and the overall structure is simple.

[0053] By setting the first abutting structure 123 and the third abutting structure 223 to abut in the first direction, when assembling the feeding assembly 10, a force toward the metal strip line 1 can be applied to the feeding structure 2 along the first direction to push the feeding structure 2 to move along the first direction, so that the first abutting structure 123 abuts against the third abutting structure 223, and the second abutting structure 124 abuts against the fourth abutting structure 224. In this way, the feeding assembly 10 can achieve a stop fit between the first coupling part 12 and the second coupling part 22 by pushing and inserting the feeding structure 2 along the first direction, thereby achieving assembly of the feeding assembly 10, which has a simple structure and is easy to use.

[0054] By setting the first abutting structure 123 and the third abutting structure 223 to abut in the first direction, when inspecting the feeding assembly 10, a force away from the metal strip line 1 can be applied to the feeding structure 2 along the first direction, the stop fit between the first abutting structure 123 and the third abutting structure 223 is released, the stop fit between the second abutting structure 124 and the fourth abutting structure 224 is released, and the feeding structure 2 is separated from the metal strip line 1. In this way, the feeding assembly 10 can separate the first coupling part 12 from the second coupling part 22, separate the metal strip line 1 from the feeding structure 2, and disassemble the feeding assembly 10 by pulling the feeding structure 2 along the first direction, and the structure is simple and easy to use.

[0055] Reference Figure 2 , Figure 5 , Figure 8 , Fig.10 In some embodiments of the present invention, one of the first coupling portion 12 and the second coupling portion 22 defines a mating hole 125 opening toward the second direction, and the other of the first coupling portion 12 and the second coupling portion 22 has a mating column 231 extending along the second direction, and the mating column 231 is passed through the mating hole 125; the radial inner circumferential surface of the mating hole 125 and the radial outer surface of the mating column 231 are the first abutment structure 123 and the third abutment structure 223, respectively.

[0056] For example, the mating hole 125 can be defined by the first coupling part 12, and the mating hole 125 can also be defined by the second coupling part 22; when the first coupling part 12 defines the mating hole 125, the second coupling part 22 is provided with a mating column 231; when the second coupling part 22 defines the mating hole 125, the first coupling part 12 is provided with a mating column 231.

[0057] In this way, the first abutment structure 123 and the second abutment structure 124 can be coupled and electrically connected in multiple directions perpendicular to the second direction, so that the first abutment structure 123 and the second abutment structure 124 have redundant electrical connections in multiple directions, so that the first abutment structure 123 and the second abutment structure 124 can be reliably coupled and electrically connected.

[0058] Moreover, in this way, the dimensional accuracy of the mating hole 125 and the mating column 231 does not need to be set too high, so that the hole diameter of the mating hole 125 of the first abutting structure 123 can be set larger, and the outer diameter of the mating column 231 can be set smaller, thereby reducing the difficulty of the processing technology of the first abutting structure 123 and the second abutting structure 124 and reducing the production cost of the first abutting structure 123 and the second abutting structure 124.

[0059] Reference Figure 7 and Figure 8 In some embodiments of the present invention, one of the second abutment structure 124 and the fourth abutment structure 224 is the bottom surface of the matching hole 125 opposite to its opening, that is, the matching hole 125 is a blind hole; the other of the second abutment structure 124 and the fourth abutment structure 224 is the end surface of the matching column 231 inserted into the matching hole 125, that is, the second abutment structure 124 and the fourth abutment structure 224 abut in the second direction.

[0060] For example, when the first coupling part 12 defines a mating hole 125 and a mating column 231 is provided on the second coupling part 22, the second abutment structure 124 can be the bottom surface of the mating hole 125 opposite to its opening, and the fourth abutment structure 224 can be the end surface of the mating column 231 inserted into the mating hole 125; when the second coupling part 22 defines a mating hole 125 and a mating column 231 is provided on the first coupling part 12, the fourth abutment structure 224 can be the bottom surface of the mating hole 125 opposite to its opening, and the second abutment structure 124 can be the end surface of the mating column 231 inserted into the mating hole 125.

[0061] In this way, the axial hole structural features of the first coupling part 12 and the second coupling part 22 can be fully utilized, so that the overall structure of the first coupling part 12 is relatively simple, the overall structure of the second coupling part 22 is relatively simple, and the total structural features of the first coupling part 12 and the second coupling part 22 are relatively few, thereby reducing the difficulty of the production process of the first coupling part 12 and the second coupling part 22, and the structure is simple and reasonable, and the layout is ingenious.

[0062] Reference Figure 2 , Figure 7 and 8In some embodiments of the present invention, the feeding assembly 10 further includes: a first medium 4, a first positioning hole 41 opening in the second direction is provided on the first medium 4, the conductive part 11 is provided on the first medium 4, and the first coupling part 12 defines a matching hole 125 opening in the second direction, that is, a matching column 231 is provided on the second coupling part 22, and a part of the first abutting structure 123 is penetrated in the first positioning hole 41. In this way, the first medium 4 can limit the first coupling part 12 through the mutual cooperation between the first positioning hole 41 and the matching column 231, so that the relative positioning of the first coupling part 12 relative to the first medium 4 is reliable, thereby improving the reliability of the feeding assembly 10.

[0063] For example, refer to Figure 2 , Figure 7 and Figure 8 The matching hole 125 extends to the portion of the first coupling portion 12 that passes through the first positioning hole 41, so that the matching distance between the first abutting structure 123 and the second abutting structure 124 in the second direction can be extended, and the matching area between the first abutting structure 123 and the second abutting structure 124 is increased, so that the first abutting structure 123 and the second abutting structure 124 can be reliably fed; moreover, in this way, the first medium 4 can limit the matching column 231 over a longer distance through the matching hole 125, so that the matching column 231 can be more reliably positioned relative to the first medium 4, thereby improving the reliability of the feeding component 10.

[0064] Reference Figure 2 , Figure 3 , Figure 8 In other embodiments of the present invention, the second abutment structure 124 is the end surface of the first coupling portion 12 facing the feeding portion 21 in the second direction, and the second coupling portion 22 further includes a first flange 232, the first flange 232 is connected to one end of the matching column 231 close to the feeding portion 21, and the first flange 232 protrudes from the radial outer surface of the matching column 231 in the radial direction of the matching column 231. For example, the first flange 232 may protrude from the radial outer surface of the matching column 231 in the second direction, the first flange 232 may also protrude from the radial outer surface of the matching column 231 in the third direction, and the first flange 232 may also be sleeved on the matching column 231.

[0065] In this way, the abutting seam between the second abutting structure 124 and the fourth abutting structure 224 can be exposed, which is convenient for operators to observe whether the first abutting structure 123 and the fourth abutting structure 224 are abutted together, and is convenient for quality inspection of the feeding assembly 10 .

[0066] Reference Figure 7 and Figure 8In some other embodiments of the present invention, the feeding assembly 10 further includes: a second medium 5, a second positioning hole opening in a second direction is provided on the second medium 5, the conductive portion 11 is provided on the second medium 5, the first coupling portion 12 defines a matching hole 125 opening in the second direction, the second coupling portion 22 has a matching column 231, and the matching column 231 is penetrated in the matching hole 125 and the second positioning hole, that is, the matching hole 125 is a through hole.

[0067] In this way, the second medium 5 can directly limit the second coupling portion 22 through the cooperation between the matching hole 125 and the matching column 231, so that the second coupling portion 22 can be reliably positioned relative to the second medium 5; at the same time, since the matching column 231 is also penetrated into the matching hole 125, the second medium 5 can also limit the first coupling portion 12 through the matching column 231, so that the first coupling portion 12 can be reliably positioned relative to the second medium 5, thereby improving the reliability of the feeding assembly 10.

[0068] Reference Figure 2 , Figure 7 and Figure 8 In other embodiments of the present invention, the first coupling portion 12 protrudes from at least one side of the conductive portion 11 in the second direction. For example, the first coupling portion 12 may protrude from the conductive portion 11 only on the side facing the feeding portion 21, the first coupling portion 12 may protrude from the conductive portion 11 only on the side away from the feeding portion 21, or the first coupling portion 12 may protrude from the conductive portion 11 on both sides in the second direction.

[0069] In this way, the structural strength of the metal strip line 1 at the first coupling part 12 can be higher, and the bending deformation of the first abutment structure 123 or the second abutment structure 124 can be effectively prevented, so that the matching column 231 can be reliably inserted into the matching hole 125, so that the second abutment structure 124 and the fourth abutment structure 224 can be matched more closely, so that the first coupling part 12 and the second coupling part 22 can be reliably fed through the second abutment structure 124 and the fourth abutment structure 224, thereby improving the overall performance of the feeding component 10.

[0070] Reference Fig. 9 and Fig.10 Optionally, the first coupling portion 12 may not protrude from the conductive portion 11, that is, the two surfaces of the first coupling portion 12 in the second direction are flush with the surfaces on the corresponding sides of the conductive portion 11. In this way, the first abutting structure 123 and the second abutting structure 124 can be obtained only by punching holes on the metal strip line 1, which reduces the difficulty of producing the first abutting structure 123 and the second abutting structure 124, reduces the difficulty of producing the first coupling portion 12, improves the production efficiency of the first coupling portion 12, and reduces the production cost of the first coupling portion 12.

[0071] Reference Fig.11 and Fig.12 According to some other embodiments of the present invention, the first coupling portion 12 is a sheet extending along the second direction, the first abutment structure 123 is the surface of the first coupling portion 12 in the first direction, and the second abutment structure 124 is the surface of the first coupling portion 12 facing away from the conductive portion 11; in this way, the metal strip wire 1 can be bent to construct the conductive portion 11 and the first coupling portion 12, which has a simple structure and is easy to produce.

[0072] The second coupling part 22 includes a matching plate 241 and a second flange 242, the matching plate 241 is connected to one end of the feeding part 21 facing the first coupling part 12, the second flange 242 is connected to one end of the matching plate 241 close to the feeding part 21, and the second flange 242 protrudes from the radial outer surface of the matching plate 241 in the first direction, the third abutment structure 223 is the surface of the matching plate 241 in the first direction, and the fourth abutment structure 224 is the surface of the second flange 242 away from the feeding part 21. In this way, the second coupling part 22 can be matched with the first coupling part 12 by inserting downward, and the second coupling part 22 can be separated from the first coupling part 12 by pulling upward, so that the disassembly method between the first coupling part 12 and the second coupling part 22 is relatively simple, which is convenient for disassembly and assembly of the feeding assembly 10.

[0073] Reference Figure 1-Figure 12 The antenna 100 according to the second aspect of the present invention comprises: a feeding assembly 10 according to the first aspect of the present invention, a metal cavity 60 and a radiation unit 70, the metal cavity 60 having at least one cavity structure 61 and an avoidance hole 62, the avoidance hole 62 being connected to the cavity structure 61, the metal strip line 1 being arranged in the cavity structure 61, the feeding structure 2 being passed through the cavity structure 61 through the avoidance hole 62; the radiation unit 70 being connected to a side of the feeding structure 2 facing away from the metal cavity 60 in the second direction.

[0074] When assembling the antenna 100, the conductive part 11 can be firstly inserted into the cavity structure 61, and then the feeding part 21 can be inserted into the cavity structure 61 and connected to the conductive part 11 through the avoidance hole 62 opened on the metal cavity 60. Compared with the feeding part 21 fixed by traditional soldering connection, the avoidance hole 62 can be set smaller, thereby reducing the influence of the feeding part 21 on the antenna 100, improving the benefit of the antenna 100, and improving the overall performance of the antenna 100.

[0075] According to the antenna 100 of the present invention, the above-mentioned feeding component 10 can make the assembly process of the antenna 100 simpler, thereby improving the production efficiency of the antenna 100; moreover, the avoidance hole 62 can be set smaller, thereby reducing the impact of the feeding component 10 on the antenna 100, improving the benefit gain of the antenna 100, and improving the overall performance of the antenna 100.
