[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0037] See also Figures 1 to 3 , Figure 1 FIG. 1 shows a cross-sectional structural diagram of an end cover and a radome 30 packaged together according to an embodiment of the present invention. Figure 2 Shows Figure 1 A schematic diagram of the enlarged structure at A. Figure 3 The schematic diagram of the structure of the end cover of one embodiment of the present invention is shown. An end cover provided by one embodiment of the present invention comprises: an end cover body 10 and a sealing strip 20. An inner limiting wall 11 and an outer limiting wall 12 are arranged around the edge of the end cover body 10, and the inner limiting wall 11 and the outer limiting wall 12 are arranged at intervals from each other and cooperate to form an assembly groove 13. The assembly groove 13 is used to install the assembly part 31 of the antenna cover 30. The sealing strip 20 is integrally formed on the inner wall of the assembly groove 13 by dispensing glue into the assembly groove 13, and the sealing strip 20 is used to have an interference fit with the assembly part 31 inserted into the assembly groove 13.

[0038] Before the end cap is assembled with the antenna cover 30, the sealing strip 20 is integrally formed on the inner wall of the assembly groove 13 by dispensing glue into the assembly groove 13. When the end cap and the antenna cover 30 are assembled together, the assembly portion 31 is inserted into the assembly groove 13 and has an interference fit with the sealing strip 20, thereby ensuring the sealing performance after the end cap body 10 and the antenna cover 30 are assembled together. In addition, when disassembly operation is required, the end cap body 10 can be removed from the assembly groove 13, which is convenient for disassembly and assembly, and there is no need to clean excess silicone glue, thereby saving packaging time and improving production efficiency.

[0039] It should be noted that, in this embodiment, the sealing strip 20 is an annular sealing strip 20, that is, the sealing strip 20 is arranged along the extension direction of the assembly groove 13, so that the sealing strip 20 can abut and cooperate with each part of the assembly part 31 in the circumferential direction, thereby ensuring better sealing.

[0040] See also Figure 2 and Figure 3In one embodiment, the sealing strip 20 includes an outer fitting portion 21. The outer fitting portion 21 is fitted and fixed on the outer limiting wall 12, and the outer fitting portion 21 is used for interference fit with the assembly portion 31, and a gap is provided between the outer edge of the outer fitting portion 21 and the outer edge of the outer limiting wall 12. The gap is defined as d, and optionally, d≦5mm. In this way, the outer edge of the outer fitting portion 21 is flush or substantially flush with the outer edge of the outer limiting wall 12, so that water outside the assembly groove 13 can be better prevented from entering the interior of the assembly groove 13.

[0041] It should be noted that the outer edge of the outer fitting portion 21 refers to the portion of the outer fitting portion 21 that is farthest from the bottom wall of the assembly groove 13. In addition, the outer edge of the outer limiting wall 12 refers to the portion of the outer limiting wall 12 that is farthest from the bottom wall of the assembly groove 13.

[0042] In one embodiment, d>0. When the assembly portion 31 is inserted into the assembly groove 13 and has an interference fit with the sealing strip 20, the assembly portion 31 squeezes the sealing strip 20, so that the outer edge of the outer fitting portion 21 is flush with the outer edge of the outer limiting wall 12, which can better prevent water outside the assembly groove 13 from entering the interior of the assembly groove 13. Optionally, d can be 1mm, 2mm, 3mm, 4mm, 5mm or other values, which are not limited here and can be flexibly adjusted and set according to actual needs. Of course, as an optional embodiment, d=0.

[0043] See also Figure 2 and Figure 4 , Figure 4 The figure shows a schematic diagram of the structure in which the assembly portion 31 of the antenna cover 30 according to an embodiment of the present invention is ready to be installed in the end cover. In one embodiment, the sealing strip 20 also includes a bottom fitting portion 22 connected to the outer fitting portion 21. The bottom fitting portion 22 is fitted and fixed on the bottom wall of the assembly groove 13, and the bottom fitting portion 22 is used to abut and cooperate with the assembly portion 31. In this way, the structure of the sealing strip 20 is high on the outside and low on the inside (that is, there is a height difference between the outer fitting portion 21 and the bottom fitting portion 22). When the assembly portion 31 is inserted into the assembly groove 13, the outer fitting portion 21 of the sealing strip 20 is tightly pressed against the antenna cover 30, and the assembly portion 31 is subjected to the force of the outer fitting portion 21 as shown in FIG. Figure 2 As shown in F1 in FIG. 1 , the assembly portion 31 and the outer bonding portion 21 are interference-fitted to form a first seal; in addition, the bottom bonding portion 22 tightly presses the end surface of the antenna cover 30, and the assembly portion 31 is also subjected to the force of the bottom bonding portion 22 as shown in FIG. Figure 2 As shown in F2 in FIG. 1 , the assembly portion 31 and the bottom fitting portion 22 abut against each other to form a second seal, thereby achieving a double sealing effect; in addition, as shown in FIG. Figure 2 As shown, the outer edge of the outer fitting portion 21 is flush or substantially flush with the outer edge of the outer limiting wall 12 , which can better prevent water outside the assembly groove 13 from entering the interior of the assembly groove 13 .

[0044] It should be noted that, in this embodiment, the outer bonding portion 21 (such as Figure 4 The inner fitting portion 23 (as shown) refers to the structure on the sealing strip 20 that is fixedly attached to the outer limiting wall 12. Figure 5 The bottom fitting portion 22 (as shown) refers to the structure on the sealing strip 20 that is fixedly attached to the inner limiting wall 11. Figure 4 or Figure 5 ) refers to a structure on the sealing strip 20 that is fitted and fixed to the bottom wall of the assembly groove 13.

[0045] See also Figure 5 , Figure 5 The schematic diagram shows the structure of the assembly part 31 of the antenna cover 30 of another embodiment of the present invention ready to be installed in the end cover. In one embodiment, the outer limiting wall 12 is provided with a leaking hole 121 connected to the assembly groove 13. The sealing strip 20 includes a bottom fitting part 22 and an inner fitting part 23 connected to the bottom fitting part 22. The bottom fitting part 22 is fitted and fixed on the bottom wall of the assembly groove 13, and the bottom fitting part 22 is used to abut with the assembly part 31. The distance between the surface of the bottom fitting part 22 away from the bottom wall of the assembly groove 13 and the bottom wall of the assembly groove 13 is less than the distance between the leaking hole 121 and the bottom wall of the assembly groove 13. The inner fitting part 23 is fitted and fixed on the inner limiting wall 11, and the inner fitting part 23 is used to have an interference fit with the assembly part 31. In this way, the structural form of the sealing strip 20 is low on the outside and high on the inside. Since a water leakage hole 121 is provided on the outer limiting wall 12, and the distance between the surface of the bottom fitting portion 22 away from the bottom wall of the assembly groove 13 and the bottom wall of the assembly groove 13 is smaller than the distance between the water leakage hole 121 and the bottom wall of the assembly groove 13, that is, if the bottom wall of the assembly groove 13 is taken as a reference surface, the height position of the water leakage hole 121 relative to the reference surface is higher than the bottom fitting portion 22 or is flush with the bottom fitting portion 22, so that it can be ensured that water entering the interior of the assembly groove 13 or accumulated water inside the assembly groove 13 can be smoothly discharged to the outside through the water leakage hole 121. In addition, since the leakage hole 121 is arranged on the outer limiting wall 12, rather than on the bottom wall of the assembly groove 13, in the process of forming the sealing strip 20 in the assembly groove 13 by dispensing, the fluid colloid is located in the bottom area of ​​the assembly groove 13 and is formed integrally, and will not be discharged outward through the leakage hole 121 on the outer limiting wall 12, and there will be no defect of blocking the leakage hole 121 after the colloid is fixed and formed, thereby ensuring the drainage effect. In addition, when the assembly part 31 is inserted into the assembly groove 13, the bottom fitting part 22 presses tightly against the end face of the antenna cover 30, and the assembly part 31 is subjected to the force of the bottom fitting part 22 as shown in FIG. Figure 5 As shown in F2 in FIG. 1 , the assembly portion 31 and the bottom bonding portion 22 abut against each other to form a first seal, thereby playing a double sealing role; the inner bonding portion 23 of the sealing strip 20 tightly presses the antenna cover 30, and the assembly portion 31 is also subjected to the force of the bottom bonding portion 22 as shown in FIG. Figure 5As shown in F1 in the figure, the assembly portion 31 and the inner fitting portion 23 are interference fit to form a second seal.

[0046] See also Figure 6 and Figure 7 , Figure 6 FIG. 1 is a schematic structural diagram showing a radome 30 according to another embodiment of the present invention, in which the assembly portion 31 is ready to be installed into the end cover. Figure 7 The schematic diagram of the structure of the end cover of another embodiment of the present invention is shown. In one embodiment, a water leakage hole 121 connected to the assembly groove 13 is provided on the outer limiting wall 12. The sealing strip 20 includes a bottom fitting portion 22. The bottom fitting portion 22 is fitted and fixed on the bottom wall of the assembly groove 13, and the bottom fitting portion 22 is used to abut and cooperate with the assembly portion 31. The distance between the surface of the bottom fitting portion 22 facing away from the bottom wall of the assembly groove 13 and the bottom wall of the assembly groove 13 is less than the distance between the water leakage hole 121 and the bottom wall of the assembly groove 13. A groove 221 is formed on the surface of the bottom fitting portion 22 facing away from the bottom wall of the assembly groove 13, and the groove 221 is used to adapt to the protrusion 311 of the assembly portion 31. In this way, the structural form of the sealing strip 20 is in the form of a groove 221. Since a leaking hole 121 is provided on the outer limiting wall 12, and the distance between the surface of the bottom fitting portion 22 which is away from the bottom wall of the assembly groove 13 and the bottom wall of the assembly groove 13 is smaller than the distance between the leaking hole 121 and the bottom wall of the assembly groove 13, that is, if the bottom wall of the assembly groove 13 is taken as a reference surface, the height position of the leaking hole 121 relative to the reference surface is higher than the bottom fitting portion 22 or is flush with the bottom fitting portion 22, so that it can be ensured that water entering the assembly groove 13 or accumulated water inside the assembly groove 13 can be smoothly discharged outward through the leaking hole 121. In addition, since the leakage hole 121 is arranged on the outer limiting wall 12, rather than on the bottom wall of the assembly groove 13, in the process of forming the sealing strip 20 in the assembly groove 13 by dispensing, the fluid colloid is located in the bottom area of ​​the assembly groove 13 and is formed integrally, and will not be discharged outward through the leakage hole 121 on the outer limiting wall 12, and will not block the leakage hole 121 after the colloid is fixed and formed, thereby ensuring the drainage effect. In addition, when the assembly part 31 is inserted into the assembly groove 13, the bottom fitting part 22 presses tightly against the end face of the antenna cover 30, and the convex part 311 of the assembly part 31 is simultaneously inserted into the groove 221, and the convex part 311 and the groove 221 are interference fit, and the force applied to it is as follows: Figure 6 The sealing form of F1, F2 and F3 shown is a circuitous path, which has better sealing performance.

[0047] See also Figure 6 and Figure 7In one embodiment, the leakage hole 121 is provided as one or more, and the plurality of leakage holes 121 are provided at intervals on the outer limiting wall 12. In this way, when the number of leakage holes 121 provided is greater, it is more conducive to drainage. It should be noted that the specific number of the leakage holes 121 can be flexibly provided and adjusted according to actual needs, and is not limited here.

[0048] See also Figure 2 In one embodiment, the inner limiting wall 11 and / or the outer limiting wall 12 are provided with a guide slope 111 at a position away from the bottom wall of the assembly groove 13. Thus, when the assembly portion 31 of the antenna cover 30 is installed in the assembly groove 13, the assembly portion 31 can be smoothly inserted and installed in the assembly groove 13 under the guidance of the guide slope 111.

[0049] It should be noted that the guide slope 111 is arranged at an angle with the bottom wall of the assembly groove 13, and the angle is, for example, 30° to 90°. Optionally, the guide slope 111 includes but is not limited to a straight surface, an arc surface, a smooth surface or a combination of one or more.

[0050] See also Figures 1 to 3 In one embodiment, an antenna device includes the end cover of any of the above embodiments, and also includes a antenna cover 30, wherein the assembly portion 31 is inserted into the assembly groove 13 and has an interference fit with the sealing strip 20.

[0051] Before the antenna device is assembled with the antenna cover 30, the sealing strip 20 is integrally formed on the inner wall of the assembly groove 13 by dispensing glue into the assembly groove 13. When the end cover and the antenna cover 30 are assembled together, the assembly portion 31 is inserted into the assembly groove 13 and has an interference fit with the sealing strip 20, thereby ensuring the sealing performance after the end cover body 10 and the antenna cover 30 are assembled together. In addition, when disassembly operation is required, the end cover body 10 can be removed from the assembly groove 13, which is convenient for disassembly and assembly, and there is no need to clean excess silicone glue, thereby saving packaging time and improving production efficiency.

[0052] See also Figure 1 , Figure 3 and Figure 8 , Figure 8 The schematic diagram of the structure of an end cover and a radome 30 packaged together in one embodiment of the present invention is shown. In one embodiment, a mounting portion 14 is provided on the end cover body 10, and the mounting portion 14 is detachably connected to the radome 30 via a fastener 15.

[0058] In the packaging method of the antenna device described above, before being assembled with the antenna cover 30, the sealing strip 20 is integrally formed on the inner wall of the assembly groove 13 by dispensing glue into the assembly groove 13, so when the end cover and the antenna cover 30 are assembled together, the assembly portion 31 is inserted into the assembly groove 13 and has an interference fit with the sealing strip 20, thereby ensuring the sealing performance after the end cover body 10 and the antenna cover 30 are assembled together. In addition, when disassembly operation is required, the end cover body 10 can be removed from the assembly groove 13, which is convenient for disassembly and assembly, and there is no need to clean excess silicone glue, thereby saving packaging time and improving production efficiency.
