Description

Technical Field

[0001] The invention belongs to the technical field of vehicle-mounted antennas, and in particular relates to a mounting structure of a large vehicle-mounted antenna. Background Art

[0002] The antenna mounting structure is an important supporting structure for microwave antenna subarrays and power division waveguides. It is characterized by large size, heavy weight, and high rigidity requirements. As an important structure supporting microwave antennas, the design of large array antenna mounting structures is an important link that affects the technical indicators of the entire microwave antenna system.

[0003] At present, there are two main forms of large array antenna installation structure products: the first is a steel welding structure, which uses steel to make the main parts of the frame, and finally uses welding to form a large antenna frame structure; the second is an aluminum alloy structure, which uses aluminum alloy to make the main parts of the frame, and finally uses welding to form a large antenna installation structure. The above two antenna installation structures have the following defects: 1. The installation structure is made of steel, which is too heavy, with a large amount of welding, large deformation, and a long processing cycle, which does not meet the development needs of new products; 2. The installation structure is made of aluminum alloy material, which has a reduced weight but relatively low strength, and also has problems such as large welding, large deformation, and long processing cycle; 3. Regardless of whether steel or aluminum is used, there are large welding and deformation, and it is difficult to guarantee the external dimensions, installation dimensions, flatness, and form and position tolerances, which directly affects the functions and performance indicators of the microwave antenna system.
