The portion of the elastic locking post extending out of the locking hole abuts against the side of the injection molding plate away from the main body. The support arm abuts against the side of the injection molding plate close to the main body. The main body defines a limiting hole. The balun passes through the limiting hole and abuts against the peripheral wall of the limiting hole. The power supply plate is located on the side of the main body away from the injection molding plate.

[0010] Optionally, the support base further includes first positioning posts, the number of which is the same as the number of elastic locking posts and corresponds one-to-one.

Furthermore, it does not damage the overall structure of the injection-molded plate, ensuring that the injection-molded plate has sufficient structural strength to support the radiating sheet, effectively preventing bending and deformation of the radiating sheet, guaranteeing the working performance of the radiating sheet, extending the life of the radiating sheet, improving the overall performance of the radiating unit, and reducing the weight of the radiating panel and the radiating unit. Moreover, the radiating sheet can be used directly without electroplating, effectively reducing the molding process of the radiating unit and lowering its production cost.

[0031] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0032] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0033] Reference Figures 1-4 This disclosure provides a radiating unit 100, including: a radiating panel 10, a balun 7 and a feed plate 8. The radiating panel 10 includes a radiating sheet 1 and an injection-molded plate 2. The radiating sheet 1 is connected to the injection-molded plate 2, and the injection-molded plate 2 supports the radiating sheet 1. For example, the radiating sheet 1 can be a copper alloy component.

[0034] By setting the injection molding plate 2 to support the radiating sheet 1, the radiating sheet 1 does not need to be made very thick to prevent deformation, and the radiating sheet 1 can be made thinner, thereby saving the cost of the radiating sheet 1 and reducing the production cost of the radiating unit 100; at the same time, the injection molding plate 2 has a lower density and lighter material, which can reduce the weight of the radiating panel 10 and the radiating unit 100.

[0035] The injection-molded plate 2 has an opening 21, and at least a portion of the radiating sheet 1 is opposite to the opening 21. This reduces the obstruction of the radiating sheet 1 by the injection-molded plate 2, allowing the radiating sheet 1 opposite to the opening 21 to radiate directly to the outside through the opening 21, thereby increasing the radiation intensity of the radiation unit 100; it also allows the radiating sheet 1 opposite to the opening 21 to directly receive radio waves through the opening 21, reducing the obstruction of radio waves by the injection-molded plate 2, thereby improving the radiation intensity and reception effect of the radiation unit 100.

[0036] One end of the balun 7 is connected to the radiating sheet 1, and the balun 7 is electrically connected to the radiating sheet 1; this allows the balun 7 to directly supply power to the radiating sheet 1, eliminating the need for electroplating the radiating sheet 1, effectively reducing the molding process of the radiating unit 100 and reducing the production cost of the radiating unit 100.

[0037] For example, the radiating sheet 1 has a first wiring hole 111, and the balun 7 has a first conductive terminal 71. The first terminal 71 passes through the first wiring hole 111 and is electrically connected to the radiating sheet 1. Specifically, the first terminal 71 and the radiating sheet 1 are soldered together using a soldering process. This allows the balun 7 to reliably supply power to the radiating sheet 1, ensuring the overall structural reliability of the radiating unit 100.

[0038] The other end of the balun 7 is connected to the feed board 8, and the balun 7 is electrically connected to the feed board 8. The feed board 8 is electrically connected to the power supply via a wiring harness. For example, the feed board 8 has a second wiring hole, and the balun 7 has a second conductive terminal 72. The second terminal 72 passes through the second wiring hole and is electrically connected to the feed board 8. Specifically, the second terminal 72 and the feed board 8 are soldered together using a soldering process. This allows the feed board 8 to reliably supply power to the balun 7, ensuring the overall structural reliability of the radiation unit 100.

[0039] According to the radiating unit 100 provided in the embodiments of this disclosure, by placing the radiating sheet 1 on the injection-molded plate 2 and providing an open hole 21 on the injection-molded plate 2 opposite to the radiating sheet 1, the radiating sheet 1 opposite to the open hole 21 can radiate and receive radio waves through the open hole 21, reducing the obstruction of radio waves by the injection-molded plate 2, thereby improving the radiation intensity and receiving effect of the radiating unit 100, and without damaging the overall structure of the injection-molded plate 2, so that the injection-molded plate 2 can have sufficient structural strength to support the radiating sheet 1, thereby effectively preventing the radiating sheet 1 from bending and deforming, ensuring the working performance of the radiating sheet 1, extending the life of the radiating sheet 1, improving the overall performance of the radiating unit 100, reducing the weight of the radiating panel 10, and reducing the weight of the radiating unit 100;

[0040] Moreover, compared to the radiating panel 10 formed by die casting, the radiating sheet 1 can be used directly without electroplating, which effectively reduces the forming process of the radiating unit 100 and reduces the production cost of the radiating unit 100.

[0041] Reference Figures 1-4 In the embodiments disclosed herein, there are multiple open holes 21, which are arranged at intervals along the wiring path of the radiating sheet 1. This allows for a larger area of ​​the radiating sheet 1 opposite to the open holes 21 while maintaining the supporting effect of the injection-molded plate 2 on the radiating sheet 1, effectively reducing the shading of the radiating sheet 1 by the injection-molded plate 2 and improving the radiation and receiving performance of the radiating unit 100.

[0042] For example, refer to Figure 5 In some embodiments of the present invention, the injection-molded plate 2 is provided with reinforcing ribs. The reinforcing ribs extend along the wiring path of the radiating sheet 1 and are spaced apart from the open hole 21. Specifically, the radiating sheet 1 includes a plurality of sub-radiating sheets 11, which are arranged in an array and spaced apart. The reinforcing ribs include outer edge reinforcing ribs 25 and spacer reinforcing ribs 26. The outer edge reinforcing ribs 25 extend along the outer contour of the injection-molded plate 2 and are located outside the open hole 21. The spacer reinforcing ribs 26 are located on both sides of the gap between two adjacent sub-radiating sheets 11. This can effectively improve the structural strength of the injection-molded plate 2 and improve the overall structural reliability of the radiating panel 10.

[0043] Reference Figures 1-4 In the embodiments of this disclosure, at least a portion of the radiant sheet 1 is embedded in the injection molding plate 2, which can effectively prevent the radiant sheet 1 from falling off the injection molding plate 2, so that the injection molding plate 2 can reliably support and fix the radiant sheet 1, thereby improving the reliability of the sub-panel.

[0044] For example, the radiating sheet 1 can be completely embedded in the injection molded plate 2. Specifically, the radiating sheet 1 can be placed in the middle of the injection mold, and then liquid plastic can be injected to allow the liquid plastic to flow to both sides of the radiating sheet 1, so that the injection molded plate 2 and the radiating sheet 1 are integrally injection molded. This allows the injection molded plate 2 to play a better protective role for the radiating sheet 1. During the assembly process of the radiating unit 100, it can effectively prevent the radiating sheet 1 from being bumped or scratched, which would lead to a decrease in performance or even failure, thereby improving the reliability of the radiating panel 10.

[0045] For example, the radiant sheet 1 can be partially embedded within the injection molding plate 2. Specifically, the radiant sheet 1 can be placed at the bottom of the injection mold, and then liquid plastic can be injected to allow the liquid plastic to flow onto the radiant sheet 1, thus integrally molding the injection molding plate 2 and the radiant sheet 1. Alternatively, the radiant sheet 1 can be heated first, and then pressed onto the injection molding plate 2 to embed the radiant sheet 1 into the injection molding plate 2. This reduces the difficulty of integrally molding the radiant sheet 1 and the injection molding plate 2, facilitates production, and can reduce production costs.

[0046] Optionally, the radiant sheet 1 can be glued to the surface of the injection molded plate 2, or the radiant sheet 1 can be fixed to the surface of the injection molded plate 2 with fasteners. This can reduce the difficulty of fixing the radiant sheet 1 to the injection molded plate 2, improve the production efficiency of the radiant panel 10, and reduce the production cost.

[0047] In some optional embodiments of this disclosure, the thickness of the radiating sheet 1 is no greater than 0.2 mm, that is, the thickness of the radiating sheet 1 can be 0.2 mm, 0.19 mm, 0.18 mm, 0.17 mm, 0.16 mm, 0.15 mm, 0.14 mm, 0.13 mm, 0.12 mm, or 0.1 mm. For example, the radiating sheet 1 can be formed by a stamping process. The stamping equipment can stamp multiple radiating sheets 1 at a time. The thinner the radiating sheet 1, the more original sheets can be stacked in each stamping process, and the more radiating sheets 1 can be stamped at a time. This can improve the production efficiency of the radiating sheet 1, reduce the cost of the radiating sheet 1, and reduce the production cost of the radiating unit 100.

[0048] Reference Figure 1 and Figure 6 In some embodiments of this disclosure, the radiating unit 100 further includes: a support base 30, which is connected between the antenna bracket and the injection molding plate 2. The support base 30 and the injection molding plate 2 are detachably connected, which facilitates the maintenance and replacement of the radiating panel 10. The support base 30 is detachably connected to the antenna bracket, which facilitates the maintenance and replacement of the radiating unit 100.

[0049] Reference Figure 1 , Figure 2 and Figure 6 In some embodiments of this disclosure, the support base 30 includes a main body 3 and a support arm 4. There are multiple support arms 4, and the multiple support arms 4 are arranged at intervals along the circumference of the main body 3. Each support arm 4 is provided with an elastic locking post 41. The injection molded plate 2 is formed with locking holes 22. The number of locking holes 22 is the same as the number of elastic locking posts 41 and they correspond one-to-one. The elastic locking post 41 passes through the corresponding locking hole 22. The part of the elastic locking post 41 that extends out of the locking hole 22 abuts against the side of the injection molded plate 2 away from the main body 3. The support arm 4 abuts against the side of the injection molded plate 2 close to the main body 3.

[0050] The radiating panel 10 is held in place by the elastic locking post 41 and the support arm 4. This allows the support base 30 to limit the radiating panel 10 in the axial direction of the elastic locking post 41, effectively preventing displacement of the radiating panel 10 relative to the balun 7 in the axial direction of the elastic locking post 41. This ensures a reliable connection between the balun 7 and the radiating panel 10, improving the reliability of the radiating unit 100. Simultaneously, it effectively reduces the vibration of the radiating panel 10 in the axial direction of the elastic locking post 41, improving the radiation performance and receiving effect of the radiating unit 100.

[0051] For example, the elastic locking post 41 includes a sub-locking post 411, which includes a connecting part 4111 and a stop part 4112. The connecting part 4111 is connected to the support arm 4 and passes through the locking hole 22. The stop part 4112 is connected to the end of the connecting part 4111 away from the support part and protrudes from the connecting part 4111. The part of the stop part 4112 protruding from the connecting part 4111 is opposite to the injection molded plate 2, and the part of the stop part 4112 protruding from the connecting part 4111 stops the side of the injection molded plate 2 away from the power supply plate 8. The cross-section of the stop part 4112 gradually decreases away from the connecting part 4111, and the stop part 4112 is generally conical.

[0052] When installing the elastic locking post 41, align the elastic locking post 41 with the locking hole 22, and then move the support base 30 toward the injection molded plate 2 to insert the stop part 4112 into the locking hole 22. Since the stop part 4112 is generally conical, when the support base 30 is pushed forcefully, the stop part 4112 can bend the connecting part 4111 inward under the force, thereby passing through the locking hole 22. Then, under the action of elastic force, it returns to its original position before installation to stop the injection molded plate 2. By setting the connecting part 4111 and the stop part 4112, the support base 30 limits the injection molded plate 2 in the axial direction of the elastic locking post 41. The structure is simple and easy to use.

[0053] Specifically, there can be multiple sub-clamping posts 411, which are arranged at intervals. This can increase the clamping force on the injection molded plate 2, so that the support seat 30 can more reliably limit the injection molded plate 2 in the axial direction of the elastic clamping posts 41, thereby improving the structural reliability of the radiation unit 100.

[0054] The main body 3 defines a limiting hole 31, through which the balun 7 passes and abuts against the peripheral wall of the limiting hole 31. The power supply plate 8 is located on the side of the main body 3 away from the injection molded plate 2. The main body 3 can limit the balun 7, effectively preventing the balun 7 from shifting relative to the radiation panel 10 in the axial direction of the elastic locking post 41, thus ensuring a reliable connection between the balun 7 and the radiation panel 10 and improving the reliability of the radiation unit 100.

[0055] Reference Figure 1 and Figure 2 In some embodiments of this disclosure, the support base 30 further includes a first positioning post 42. The number of the first positioning posts 42 is the same as the number of the elastic locking posts 41 and they correspond one-to-one. The first positioning posts 42 and the corresponding elastic locking posts 41 are spaced apart. The injection molded plate 2 has a first positioning hole 23. The number of the first positioning holes 23 is the same as the number of the first positioning posts 42 and they correspond one-to-one. The first positioning posts 42 pass through the corresponding first positioning holes 23.

[0056] Multiple first positioning posts 42 and multiple first positioning holes 23 cooperate with each other to limit the radiating panel 10 in the circumferential direction of the elastic locking post 41. This effectively prevents the radiating panel 10 from shifting relative to the balun 7 in the circumferential direction of the elastic locking post 41, ensuring a reliable connection between the balun 7 and the radiating panel 10 and improving the reliability of the radiating unit 100. At the same time, this effectively reduces the vibration of the radiating panel 10 in the circumferential direction of the elastic locking post 41, improving the radiation performance and receiving effect of the radiating unit 100.

[0057] Reference Figure 1 and Figure 2 In some embodiments of this disclosure, the support base 30 has a recess 24, the opening of which is located on the side of the injection molded plate 2 away from the main body 3. Specifically, the recess 24 protrudes from the injection molded plate 2, and reinforcing ribs are located on the side of the injection molded plate 2 near the power supply plate 8. This reduces the thickness of the injection molded plate 2, making its structure more compact.

[0058] The first positioning hole 23 and the locking hole 22 penetrate the bottom wall of the sink 24, the first positioning post 42 is located inside the sink 24, and the elastic locking post 41 is located inside the sink 24. This can reduce the obstruction of radio waves by the elastic locking post 41 and the first positioning post 42, and improve the radiation intensity and reception effect of the radiation unit 100.

[0059] Reference Figure 6 In some embodiments of this disclosure, the support base 30 further includes a support ring 5, which is generally annular and connected to all the support arms 4. The support ring 5 is close to the elastic retaining post 41 and abuts against the side of the injection-molded plate 2 near the main body 3. By connecting multiple support arms 4 with the support ring 5, the structural strength of the support arms 4 can be improved, preventing large deformation of the support arms 4, so that the support base 30 can reliably support the radiation panel 10 and improve the reliability of the radiation unit 100 structure.

[0060] By setting a support ring 5 between the support arm 4 and the radiation panel 10, when the radiation panel 10 and the support base 30 are installed together, the radiation panel 10 and the support arm 4 squeeze the support ring 5, which can make the stop part 4112 press tightly against the radiation panel 10, thereby more effectively limiting the radiation panel 10 in the axial direction of the elastic pin 41, reducing the vibration of the radiation panel 10 in the axial direction of the elastic pin 41, improving the structural reliability of the radiation unit 100, and improving the overall performance of the radiation unit 100.

[0061] Reference Figure 5 and Figure 6 In some embodiments of this disclosure, the main body 3 is provided with a plurality of second positioning posts 32, which are arranged asymmetrically. Specifically, the number of second positioning posts 32 can be three, four, or five. The power supply board 8 has second positioning holes 81, and the number of second positioning posts 32 is the same as the number of second positioning holes 81 and corresponds one-to-one. The second positioning posts 32 pass through the corresponding second positioning holes 81. The plurality of second positioning posts 32 and the second positioning holes 81 can effectively position the power supply board 8, so that the power supply board 8 and the balun 7 can be positioned together relatively accurately.

[0062] The asymmetrical arrangement of multiple second positioning posts 32 can prevent mistaken installation of the feed plate 8, ensuring that the feed plate 8 can be correctly installed with the balun 7, thus improving the reliability of the radiating unit 100 structure. The structure is simple and easy to use.

[0063] Reference Figure 1 and Figure 6 In some embodiments of this disclosure, the support base 30 further includes a cable clamp 6, which is connected to the main body 3 and is located near the feed plate 8. The cable clamp 6 is used to fix the wire harness connected to the feed plate 8. This prevents the wire harness from shaking relative to the feed plate 8, keeps the section of the wire harness from the cable clamp 6 to the feed plate 8 fixed relative to the feed plate 8, and reliably connects the wire harness to the feed plate 8, allowing the wire harness to reliably supply power to the feed plate 8 and improving the reliability of the radiation unit 100.
