[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use.

[0027] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to actual proportional relationships. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0029] like Figure 1 and Figure 2 As shown, in this embodiment, the sheet metal vibrator includes: a polygonal radiating surface 10, a plurality of feed plates 20, and a plurality of pin portions 30. Each corner of the polygonal radiating surface 10 is bent downward to form a bent plate 11, and the number of sides of the polygonal radiating surface 10 is an even number. The plurality of feed plates 20 are connected to the polygonal radiating surface 10 and arranged in an array, and each feed plate 20 extends downward. The plurality of pin portions 30 are arranged in a one-to-one correspondence with the plurality of feed plates 20, and each pin portion 30 is arranged at the bottom of the corresponding feed plate 20.

[0030] Applying the technical solution of this embodiment, each corner of the polygonal radiating surface 10 is bent downward to form a bent plate 11, multiple feed plates 20 are connected to the polygonal radiating surface 10, and multiple feed plates 20 are arranged in an array. Multiple pin portions 30 are provided in a one-to-one correspondence with the multiple feed plates 20, and each pin portion 30 is provided at the bottom of the corresponding feed plate 20. Through the above-mentioned arrangement, since the bent plate 11 bends and extends downward, it is possible to effectively reduce the space occupied by the sheet metal vibrator, thereby achieving miniaturization of the sheet metal vibrator. Therefore, the technical solution of this embodiment effectively solves the problem of large space occupied by the sheet metal vibrator in the related art.

[0031] It should be noted that through the above design, the size of the sheet metal vibrator can be greatly reduced while maintaining good radiation performance, so that the equipment can achieve a lighter and more compact design without sacrificing communication quality, thereby enhancing the market competitiveness of the product.

[0032] Specifically, in this embodiment, the polygonal radiation surface 10 , the feeding plate 20 and the pin portion 30 are all made of metal.

[0033] like Figures 1 to 5As shown, in this embodiment, each pin portion 30 extends toward the center line of the polygonal radiating surface 10. The above arrangement enables the pin portion 30 to be located inside the plurality of feeding plates 20, thereby effectively reducing the space occupied by the pin portion 30.

[0034] It should be noted that, in the prior art, a plurality of pin portions extend outward, so that the area of ​​the circle defined by the plurality of pin portions is larger than the area of ​​the circle defined by the plurality of pin portions 30 of this embodiment.

[0035] like Figures 1 to 5 As shown, in this embodiment, the polygonal radiating surface 10, the multiple feed plates 20, and the multiple pin portions 30 are an integrally stamped structure. This integrated molding process not only simplifies the production process and reduces costs, but also enhances the structural stability and durability of the sheet metal vibrator, making it suitable for large-scale production and able to meet the high demand for antennas in communication equipment.

[0036] Specifically, the processing process of the sheet metal vibrator of this embodiment is as follows: first, a notch is opened in the diagonal direction on the polygonal radiating surface 10, the plate in the notch is bent downward to form a feeding plate 20, and the end of the feeding plate 20 away from the polygonal radiating surface 10 is bent inward to form a pin portion 30.

[0037] It should be noted that the process advantage of one-piece stamping is that it can achieve high-precision component manufacturing at a lower cost. At the same time, since it is an integral molding, it avoids the problems of signal leakage and insufficient mechanical strength that may be caused by the connections between components.

[0038] like Figures 3 to 5 As shown, in this embodiment, the bent plate 11 is perpendicular to the polygonal radiating surface 10, and the feed plate 20 is perpendicular to the pin portion 30. The above-mentioned vertical arrangement optimizes the physical layout of the antenna, reduces space occupation, and ensures the vertical radiation characteristics of the signal.

[0039] Specifically, this vertical setting design not only fully utilizes the three-dimensional space inside the sheet metal vibrator and reduces the plane occupancy of the antenna, but also ensures the vertical radiation characteristics of the signal, improves the adaptability and efficiency of the antenna in space-constrained devices, and can still achieve good wireless communication capabilities in limited space.

[0040] like Figures 1 to 5As shown, in this embodiment, polygonal radiating surface 10 is a first rectangular plate, and bent plate 11 is a second rectangular plate. Both the first and second rectangular plates offer excellent stability and structural strength, ensuring the antenna's performance in a variety of environments. This ensures compatibility with communication devices of various standard sizes and simplifies the antenna's layout and installation within the device. The stability of the rectangular structure ensures the antenna maintains good operating condition despite environmental influences.

[0041] like Figure 1 and Figure 2 As shown, in this embodiment, the feed sheet 20 includes a first segment 21 and a second segment 22. The first segment 21 is connected between the second segment 22 and the polygonal radiating surface 10, and the width of the first segment 21 is greater than the width of the second segment 22. The above arrangement can reduce the use of materials and can better connect with the pin portion 30. At the same time, it can make the pin portion 30 correspond to the pad and prevent the pin portion 30 from protruding outward from the pad.

[0042] like Figures 1 to 3 As shown, in this embodiment, the sheet metal antenna further includes a plurality of observation holes 40, which are spaced apart on the polygonal radiating surface 10. The observation holes 40 are provided in a one-to-one correspondence with the plurality of pin portions 30, with each observation hole 40 being located directly above a corresponding pin portion 30. The provision of the observation holes 40 facilitates visual inspection of the pin portions 30 during assembly, ensuring proper installation of the pin portions 30, improving production efficiency and product quality, and is particularly suitable for antenna assembly on automated production lines.

[0043] like Figures 1 to 3 As shown, in this embodiment, the addition of the observation hole 40 makes the antenna assembly process on the automated production line more intuitive and efficient, can monitor the installation status of the pin part in real time, improve the accuracy and speed of assembly, and reduce the error rate in the production process. It is particularly suitable for large-scale automated production environments, such as the production line of modern communication equipment, and significantly improves product quality and production efficiency.

[0044] like Figures 1 to 3 As shown, in this embodiment, the pin portion 30 is provided with an escape notch 31, which is located on the side of the pin portion 30 away from the corresponding feed plate 20. The design of the escape notch 31 avoids interference between the pin portion 30 and other components, simplifying the internal structure design of the device. In addition, the provision of the escape notch 31 can improve the welding effect, thereby improving the performance of the antenna.

[0045] The arrangement of the avoidance notch 31 can provide an avoidance space for the solder, thereby enabling the solder to be better connected to the pin portion.

[0046] Specifically, the design of the avoidance notch 31 takes into account the compatibility of the antenna with other components inside the device, avoids interference between the pin portion 30 and other components inside the device, simplifies the internal structure design, and thus can better realize the integration of the antenna and improve the overall design and production efficiency of the device.

[0047] According to another aspect of the present application, an antenna is provided. Figure 6 and Figure 7 As shown, the antenna of this embodiment includes a sheet metal vibrator, which is the sheet metal vibrator described above. Since the bending plate 11 of the sheet metal vibrator is bent downward and the pin portion 30 extends toward the center, the size of the sheet metal vibrator is effectively reduced, thereby achieving miniaturization of the sheet metal vibrator. Therefore, the antenna having the sheet metal vibrator also has the above-mentioned advantages.

[0048] like Figure 6 and Figure 7 As shown, in this embodiment, the antenna also includes a PCB board 50 and a feed network 60. The feed network 60 is arranged on the PCB board 50. The feed network 60 includes a plurality of pads 61. The plurality of pads 61 are arranged in a one-to-one correspondence with the plurality of pin portions 30, and each pin portion 30 is connected to a corresponding pad 61. This antenna design not only improves the stability and efficiency of signal transmission, but also optimizes the integration of the antenna with other components of the device, making it suitable for various scenarios requiring high-performance wireless communication. This antenna design improves the stability and efficiency of signal transmission through the optimized structure of the sheet metal vibrator and the precise docking with the PCB board 50.

[0049] Specifically, due to the reduction in antenna space, the distance between the lines of the feed network is very close, which will cause some unnecessary coupling. Therefore, in the technical solution of this embodiment, metallized vias are provided on the feed network 60 to reduce these effects by adding metallized vias between the feed networks 60.

[0050] Compared with the existing traditional vibrators, the sheet metal vibrator of this embodiment has four diagonal parts of the polygonal radiating surface 10 bent downward, and the pin part 30 bent inward, which can effectively reduce the space occupied by the sheet metal vibrator and is more conducive to the wiring of the feeding network 60 and the implementation of the solution; adding metallized vias between the lines of the feeding network 60 to introduce the current generated on the surface into the grounding structure on the back of the PCB board 50 can effectively reduce the negative impact of coupling; due to the inward bending of the pin part 30, the polygonal radiating surface 10 blocks the welding condition of the sheet metal vibrator and the feeding network 60, and the technical solution of this embodiment provides an observation hole 40 on the polygonal radiating surface 10 and an avoidance gap 31 on the pin part 30, which can effectively solve the above problem.

[0051] The design of the sheet metal antenna in this embodiment, through the corner bends of the polygonal radiating surface 10 and the extension direction of the pin portion 30, creates a unique structure that not only improves the antenna's radiation efficiency but also optimizes its size and weight. The integrated stamping process simplifies the production process, reduces costs, and enhances structural stability and durability. The presence of the inspection hole 40 and the avoidance notch 31 facilitates visual inspection and avoidance of the pin portion 30 during assembly, further improving production efficiency and product quality.

[0052] Specifically, the overall design of the technical solution of this embodiment embodies innovation and practicality, bringing significant improvements and enhancements to the field of antenna technology. At the same time, its unique structural design can also reduce electromagnetic interference, improve communication quality, and is suitable for scenarios with complex electromagnetic environments.

[0053] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0054] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0055] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
