Description

Support components, antenna devices and base stations This application claims priority to Chinese Patent Application No. 202422661164.0, filed on October 31, 2024, entitled “Support Member, Antenna Device and Base Station”, the entire contents of which are incorporated herein by reference. Technical Field This application relates to the field of wireless communication technology, and in particular to a support, antenna device and base station. Background Technology Support components are crucial parts of antenna devices. They support the radome, protecting the internal structure from damage caused by static pressure, stepping, impacts, or pushing/pulling of the radome. Support components can also support the frequency selector surfaces inside the antenna device to meet various electrical requirements. However, existing support components are complex in structure and expensive to manufacture. Summary of the Invention This application provides a support member, an antenna device, and a base station. The support member of this application has a simple structure, high structural strength, and low cost. In a first aspect, embodiments of this application provide a support member applied to an antenna device. The support member includes a carrier portion, a first connecting portion, and a second connecting portion. The first connecting portion is fixedly connected to one end of the carrier portion, and the second connecting portion is fixedly connected to the other end of the carrier portion. The carrier wall of the carrier portion is the external wall of the support member, and the carrier wall encloses a hollow cavity. Understandably, the carrier wall is a structure visible from the outside of the support member. The embodiments of this application, by setting a bearing wall and forming a hollow cavity around it, make the structure of the support simple while ensuring high structural strength and large supporting force. This helps to reduce the material used in the support, making the support lighter and reducing its manufacturing cost. In one possible implementation, the hollow cavity extends from one end of the supporting portion to the other end. By extending the hollow cavity from one end of the supporting portion to the other end, the material used in the support component can be effectively reduced, the structural complexity of the support component can be decreased, and the manufacturing cost of the support component can be reduced. In one possible implementation, the thickness of the bearing wall is greater than or equal to 1 mm and less than or equal to 3 mm. Setting the thickness of the bearing wall to be greater than or equal to 1 mm and less than or equal to 3 mm helps to ensure the structural strength of the support and achieve weight reduction. If the thickness of the bearing wall is less than 1 mm, the bearing wall is thin, resulting in low structural strength of the support; if the thickness of the bearing wall is greater than 3 mm, the bearing wall is thick, requiring more material and increasing cost. In one possible implementation, the cross-section of the load-bearing part is square, trapezoidal, circular, fan-shaped, or "日"-shaped. By setting the cross-section of the load-bearing part to be square, trapezoidal, circular, fan-shaped, or "日"-shaped, the load-bearing area of the load-bearing part can be effectively increased, and the load-bearing part can have a larger moment of inertia, so that the load-bearing part can have better load performance, such as bending resistance and compression resistance. In one possible implementation, the areas of any two cross-sections of the support portion are equal. By ensuring that the areas of any two cross-sections of the support portion are equal, the structure of the support portion is simplified, which helps reduce the manufacturing difficulty and simplifies the manufacturing process, thereby reducing manufacturing costs. Furthermore, the equal areas of any two cross-sections of the support portion result in good dimensional uniformity and a pleasing visual appearance. In one possible implementation, the load-bearing portion includes a first cross-section and a second cross-section, which are arranged along the extending direction of the load-bearing portion. The areas of the first and second cross-sections are not equal. The cross-sectional area of the load-bearing portion can be adaptively adjusted according to the different stress conditions in different regions, thereby improving the design flexibility of the load-bearing portion. In one possible implementation, the load-bearing portion includes a first segment, a second segment, and a third segment arranged sequentially. The first cross-section is the cross-section of the second segment, and the second cross-section is the cross-section of either the first segment or the third segment. The area of the cross-section of the first segment is smaller than the area of the cross-section of the second
