[0036] 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.

[0037] The feeding assembly 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0038] Reference Figure 1-Figure 9 The feeding assembly 10 according to the first aspect of the present invention is used in an antenna 100, and 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), and the first coupling portion 12 is connected to one end of the conductive portion 11 in the first direction;

[0039] 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 accompanying drawing), and the second coupling portion 22 is connected to one end of the feeding portion 21 in the second direction. For example, the radiation unit 70 can be connected to one end of the feeding portion 21 away from the second coupling portion 22.

[0040] The second coupling portion 22 is tightly against the first coupling portion 12, wherein the first direction intersects with the second direction, for example, the first direction may be perpendicular to the second direction. For example, the feeding portion 21 may be a feeding balun.

[0041] It should be noted that the second coupling part 22 is pressed against the first coupling part 12, which means that when the second coupling part 22 contacts the first coupling part 12, a force is generated between the two. For example, the interaction force between the first coupling part 12 and the second coupling part 22 may be caused by the elastic deformation generated by the first coupling part 12, the interaction force between the first coupling part 12 and the second coupling part 22 may also be caused by the elastic deformation generated by the second coupling part 22, the interaction force between the first coupling part 12 and the second coupling part 22 may also be caused by the gravity of the first coupling part 12 itself, the interaction force between the first coupling part 12 and the second coupling part 22 may also be caused by the gravity of the second coupling part 22 itself, and the interaction force between the first coupling part 12 and the second coupling part 22 may also be caused by an external force structure.

[0042] 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 pressed against each other; 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 pressed against each other, or they can be in non-contact electrical connection when they are pressed against each other; 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.

[0043] Reference Figure 7 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 pressing the second coupling part 22 against the first coupling part 12, the first coupling part 12 and the second coupling part 22 can be closely fitted together, preventing the first coupling part 12 and the second coupling part 22 from shaking relative to each other, thereby causing 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.

[0044] Moreover, when assembling the feeding assembly 10, since the first coupling portion 12 and the second coupling portion 22 can be reliably electrically connected after the second coupling portion 22 is pressed against the first coupling portion 12, 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.

[0045] When the feeding assembly 10 is inspected and repaired, since the first coupling part 12 and the second coupling part 22 are only abutted together under the action of force, rather than being relatively fixed by 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.

[0046] According to the feeding assembly 10 of the present invention, by pressing the first coupling part 12 and the second coupling part 22 together, the first coupling part 12 and the second coupling part 22 can be closely fitted together to meet the feeding requirements of the antenna 100. Moreover, it is not necessary to couple the first coupling part 12 and the second coupling part 22 together by using the traditional soldering connection method, and it is not necessary to design a soldering connection process when coupling and connecting the first coupling part 12 and the second coupling part 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.

[0047] Reference Figure 1-Figure 9 According to some embodiments of the present invention, the second coupling portion 22 presses against the first coupling portion 12 to generate elastic deformation. The feeding portion 21 is used to support the radiation unit 70 and requires a certain structural strength, while the conductive portion 11 is used for power supply and the structural strength can be set to be lower. By setting the second coupling portion 22 to press against the first coupling portion 12 to generate elastic deformation, the structural strength characteristics between the feeding portion 21 and the conductive portion 11 are cleverly utilized, the conception is ingenious, and the layout is reasonable.

[0048] Reference Figure 2 , Figure 5 and Fig. 9 In some embodiments of the present invention, the feeding assembly 10 further includes: a first medium 3, the first medium 3 extends along the first direction, and the first medium 3 defines a coupling slot 31, the coupling slot 31 has an opening facing the second direction, the conductive portion 11 is provided on the first medium 3, and the conductive portion 11 is located outside the coupling slot 31, the first coupling portion 12 is provided through the coupling slot 31, and the second coupling portion 22 is provided in the coupling slot 31, and in a direction perpendicular to the first direction, the first coupling portion 12 is pressed against the side wall of the coupling slot 31. For example, the direction perpendicular to the first direction may be the first direction, and the direction perpendicular to the first direction may also be the third direction (refer to the e3 direction in the accompanying drawings), and the first direction intersects with the third direction; specifically, the first direction may be perpendicular to the third direction.

[0049] The first coupling part 12 and the second coupling part 22 are both inserted into the coupling groove 31, and the coupling groove 31 can play a role of limiting protection for the first coupling part 12 and the second coupling part 22, thereby reducing the probability that the first coupling part 12 and the second coupling part 22 are separated due to the force intersecting the first direction on the first coupling part 12, and reducing the probability that the first coupling part 12 and the second coupling part 22 are separated due to the force intersecting the first direction on the second coupling part 22, so that the first coupling part 12 and the second coupling part 22 can be reliably maintained in a state where they can be fed normally, thereby improving the reliability of the feeding assembly 10.

[0050] The two side walls of the coupling slot 31 in the first direction are the first side walls 311, the side wall of the second coupling slot 31 opposite to its opening in the second direction is the second side wall, and the two side walls of the coupling slot 31 in the third direction are the third side walls. For example, the second coupling portion 22 can force the first coupling portion 12 to deform by abutting against the side wall of the coupling slot 31 and the first coupling portion 12 in a direction perpendicular to the first direction; the second coupling portion 22 can also force the first coupling portion 12 to deform by transferring the force applied by the external force structure to the first coupling portion 12 in a direction perpendicular to the first direction.

[0051] Specifically, refer to Figure 2 , Figure 5 and Fig. 9 When the second coupling portion 22 stops against the side wall of the coupling groove 31 and the first coupling portion 12 in a direction perpendicular to the first direction, forcing the first coupling portion 12 to deform; the two surfaces of the second coupling portion 22 in the first direction can respectively abut against one of the first side walls 311 and the first coupling portion 12, forcing the first coupling portion 12 to move toward the other first side wall 311; the second coupling portion 22 can also stop against one of the third side walls and the first coupling portion 12 respectively through its two surfaces in the third direction, so as to force the first coupling portion 12 to move toward the other third side wall.

[0052] In this way, friction force can be generated between the first coupling part 12 and the second coupling part 22, so that the relative positioning of the first coupling part 12 and the second coupling part 22 is reliable, and friction force is generated between the second coupling part 22 and one of the first side walls 311, so that the second coupling part 22 and the first medium 3 are reliably positioned, so that the first medium 3 can position the second coupling part 22, and the first medium 3 can position the first coupling part 12 through the second coupling part 22, so that the overall structure of the feeding assembly 10 is more stable, and the feeding of the feeding assembly 10 is stable.

[0053] Specifically, when the second coupling portion 22 transfers the force applied by the external force structure to the first coupling portion 12 in a direction perpendicular to the first direction, forcing the first coupling portion 12 to deform, the external force structure may be an elastic member or a magnetic component, which applies force to the second coupling portion 22 through mutual attraction or mutual repulsion. Figure 2 and Figure 5 When the external force-applying structure is an elastic member, the external force-applying structure may be a rubber member or a spring member.

[0054] In this way, the external force-applying structure can always maintain the state of applying force to the second coupling part 22, and the second coupling part 22 can always maintain the state of applying force to the first coupling part 12, thereby preventing the first coupling part 12 from being separated from the second coupling part 22 due to elastic attenuation caused by long-term force, so that the second coupling part 22 and the first coupling part 12 can be reliably stopped, thereby improving the reliability of the feeding assembly 10.

[0055] Optionally, refer to Figure 8 and Fig. 9 The second coupling part 22 can also stop the first coupling part 12 through its upper end surface in the second direction, that is, the second coupling part 22 stops against the first coupling part 12 in the second direction, so that the second coupling part 22 can use its own gravity to force the first coupling part 12 to move closer to the second side wall; this solution has a simple structure and is easy to disassemble and assemble.

[0056] In some embodiments of the present invention, the second coupling portion 22 presses the first coupling portion 12 in at least two directions. For example, the second coupling portion 22 may press the first coupling portion 12 in both the first direction and the second direction, the second coupling portion 22 may press the first coupling portion 12 in both the first direction and the third direction, the second coupling portion 22 may press the first coupling portion 12 in both the second direction and the third direction, or the second coupling portion 22 may press the first coupling portion 12 in both the first direction, the second direction, and the third direction.

[0057] Specifically, when the second coupling part 22 presses the first coupling part 12 in both the first direction and the second direction, the first coupling part 12 may include a first stop sheet and a second stop sheet, the first stop sheet is connected to the feeding part 21, the large surface of the first stop sheet is toward the first coupling part 12 along the first direction, the second stop sheet is connected to the end of the first stop sheet facing away from the feeding part 21 in the second direction, and the large surface of the second stop sheet is toward the first coupling part along the second direction, that is, the third stop sheet stops with the upper end surface of the second coupling part 22 in the second direction.

[0058] Specifically, when the second coupling part 22 presses the first coupling part 12 in the first direction and the third direction, the first coupling part 12 may include a first stop sheet and a third stop sheet, the first stop sheet is connected to the feeding part 21, the large surface of the first stop sheet is toward the first coupling part 12 along the first direction, and the large surface of the third stop sheet is toward the first coupling part 12 along the third direction; wherein the third stop sheet can be connected to one end of the first stop sheet in the third direction, and the third stop sheet can be connected to the feeding part 21.

[0059] Specifically, when the second coupling portion 22 presses the first coupling portion 12 in both the second direction and the third direction, the first coupling portion 12 may include a second stop sheet and a third stop sheet, the third stop sheet is connected to the feeding portion 21, a large surface of the third stop sheet is toward the first coupling portion 12 along the third direction, the second stop sheet is connected to an end of the third stop sheet away from the feeding portion 21 in the second direction, and a large surface of the second stop sheet is toward the first coupling portion 12 along the second direction;

[0060] Specifically, when the second coupling part 22 presses the first coupling part 12 in the first direction, the second direction and the third direction, the first coupling part 12 may include a first stop sheet, a second stop sheet and a third sheet, the first stop sheet is connected to the feeding part 21, and the large surface of the first stop sheet is toward the first coupling part 12 along the first direction, the third stop sheet is connected to the feeding part 21, and the large surface of the third stop sheet is toward the first coupling part 12 along the third direction, and the large surface of the second stop sheet is toward the first coupling part 12 along the second direction; wherein the second stop sheet can be connected to an end of the first stop sheet that faces away from the feeding part 21 in the second direction, and or the second stop sheet can also be connected to an end of the third stop sheet that faces away from the feeding part 21 in the second direction.

[0061] In this way, the anti-interference ability of the first coupling part 12 and the second coupling part 22 can be improved, and the friction generated between the first coupling part 12 and the second coupling part 22 can be further increased, and the probability of the first coupling part 12 and the second coupling part 22 being separated due to the force intersecting the first direction on the first coupling part 12 or the second coupling part 22 can be reduced, so that the first coupling part 12 and the second coupling part 22 can be reliably maintained in a state where normal feeding can be performed, thereby improving the reliability of the feeding assembly 10.

[0062] Reference Figure 2-Figure 5 In some embodiments of the present invention, the first coupling portion 12 is in a long strip shape, one end of the first coupling portion 12 is located outside the coupling slot 31, the other end of the first coupling portion 12 is located inside the coupling slot 31, and the other end of the first coupling portion 12 extends toward the end away from the conductive portion 11. In this way, the portion of the first coupling portion 12 extending into the coupling slot 31 can be placed at an angle.

[0063] Reference Figure 2 and Figure 5 The second coupling portion 22 is inserted into the coupling groove 31, and the two surfaces of the second coupling portion 22 in the first direction are respectively the first surface and the second surface, the first surface abuts against the side wall of the coupling groove 31, and the second surface presses against the first coupling portion 12 and abuts against the side wall of the coupling groove 31. That is, the total size of the first coupling portion 12 and the second coupling portion 22 in the first direction is interference-fitted with the size of the coupling groove 31 in the first direction.

[0064] In this way, there is no need to set up an external force-applying structure to generate force interaction between the first coupling part 12 and the second coupling part 22, thereby preventing the first coupling part 12 from being separated from the second coupling part 22 due to elastic attenuation caused by long-term force on the first coupling part 12, so that the second coupling part 22 and the first coupling part 12 can be reliably stopped, the structure is simple and reliable, and the reliability of the feeding assembly 10 is improved.

[0065] Reference Figure 2 and Figure 5 In some embodiments of the present invention, a pressing spring sheet 32 ​​is provided on the first medium 3, and the pressing spring sheet 32 ​​includes a connecting portion 321 and a spring sheet portion 322, the connecting portion 321 is connected to the first medium 3, and the connecting portion 321 is located on the side of the coupling slot 31 away from the conductive portion 11 in the first direction, the spring sheet portion 322 is connected to the end of the connecting portion 321 away from the first medium 3 in the second direction, and the spring sheet portion 322 extends toward the coupling slot 31, and the projection of the spring sheet portion 322 on the projection plane is at least partially located in the coupling slot 31, wherein the projection plane is perpendicular to the second direction. That is, the spring sheet portion 322 extends obliquely toward the coupling slot 31; that is, in the direction toward the conductive portion 11, the distance between the spring sheet portion 322 and the first medium 3 in the second direction is gradually reduced.

[0066] In this way, the surface of the spring sheet portion 322 facing away from the coupling groove 31 can guide the second coupling portion 22, so that the second coupling portion 22 can slide into the coupling groove 31 along the surface of the spring sheet portion 322 facing away from the coupling groove 31. At the same time, since the pressure spring sheet 32 ​​is provided to apply a force toward the first coupling portion 12 to the second coupling portion 22, the second coupling portion 22 does not need to apply a force to the first coupling portion 12 by means of an interference fit with the coupling groove 31, and the size of the coupling groove 31 can be set larger, thereby facilitating the insertion of the second coupling portion 22 into the coupling groove 31.

[0067] Reference Figure 8 and Fig. 9In some embodiments of the present invention, the first coupling portion 12 includes a front abutment segment 121 and a side abutment segment 122. The front abutment segment 121 is connected to the conductive portion 11, and the front abutment segment 121 is inserted into the coupling slot 31. There are two side abutment segments 122, and the two side abutment segments 122 are respectively connected to the two ends of the front abutment segment 121 in the third direction. The side abutment segment 122 extends toward the opening of the coupling slot 31 in the second direction. The front abutment segment 121 and the two side abutment segments 122 jointly define a U-shaped slot.

[0068] The second coupling portion 22 includes a feeding section 221 and a butt joint 222, the butt joint 222 is connected to one end of the feeding section 221, and the butt joint 222 is inserted into the U-shaped groove, the surface of the butt joint 222 facing away from the feeding section 221 is the third surface, and the two surfaces of the butt joint 222 in the third direction are the fourth surfaces, the third surface abuts against the front abutment section 121 in the second direction, and the fourth surface abuts against the corresponding side abutment section 122 in the third direction.

[0069] The first direction intersects with the third direction, and the second direction intersects with the third direction. For example, the first direction may be perpendicular to the second direction, the first direction may be perpendicular to the third direction, and the second direction may be perpendicular to the third direction.

[0070] In this way, the first coupling part 12 and the second coupling part 22 can be electrically connected in the second direction through the third surface and the front abutment section 121, and the first coupling part 12 and the second coupling part 22 can be electrically connected in the third direction through the fourth surface and the side abutment section 122, thereby realizing a redundant electrical connection design between the first coupling part 12 and the second coupling part 22, reducing the probability that the first coupling part 12 and the second coupling part 22 are separated due to the force intersecting the first direction on the first coupling part 12 or the second coupling part 22, so that the first coupling part 12 and the second coupling part 22 can be reliably maintained in a state where they can be fed normally, thereby improving the reliability of the feeding assembly 10, and having a simple structure and convenient assembly.

[0071] Reference Figure 8 and Fig. 9 In some embodiments of the present invention, the spacing between one end of the two side abutment sections 122 away from the front abutment section 121 in the third direction is a first distance, and in the direction toward the front abutment section 121, the distance between the two fourth surfaces in the third direction decreases, and the spacing between one end of the two fourth surfaces close to the front abutment section 121 in the third direction is a second distance, and the spacing between one end of the two fourth surfaces away from the front abutment section 121 in the third direction is a third distance, the second distance is less than the first distance, and the third distance is greater than or equal to the first distance.

[0072] By setting the second distance to be smaller than the first distance, it is possible to facilitate the insertion of the abutment joint 222 into the U-shaped groove. By setting the third distance to be larger than the first distance, when the abutment joint 222 is inserted toward the front abutment section 121, the fourth surface can contact the side abutment section 122, and the fourth surface can exert a force on the side abutment section 122, causing the side abutment section 122 to undergo elastic deformation, so that the fourth surface is tightly attached to the side abutment section 122, and the fourth surface and the side abutment section 122 are reliably abutted.

[0073] Reference Figure 5 , Figure 6 and Fig. 9 In some optional embodiments of the present invention, the second coupling portion 22 has a connected torsion section 225 and a stop section 226, the stop section 226 abuts against the first coupling portion 12, and the torsion section 225 is twisted relative to the stop section 226 by an angle greater than or equal to 30°; for example, the stop section 226 can be the portion of the first coupling portion 12 inserted into the coupling groove 31, specifically, the stop section 226 can be a stop head. It should be understood that the torsion section 225 has a certain rotational deformation capability, that is, the torsion section 225 can apply a certain rotational force to the stop section.

[0074] In this way, the stop section 226 can exert a force on the first coupling part 12, so that the second coupling part 22 can press the first coupling part 12, and there is no need to set an external force structure, which is simple in structure and ingenious in design. Moreover, in this way, there is no need to make the first coupling part 12, the second coupling part 22 and the coupling groove 31 interference fit, so that the coupling groove 31 can be set larger, so that the first coupling part 12 and the second coupling part 22 can be inserted into the coupling groove 31 more conveniently.

[0075] Reference Figure 1-Figure 9 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.

[0076] 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.

[0077] 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.
