Description

Technical Field

[0001] The utility model relates to the technical field of radar housings, in particular to a radar housing impact resistance testing mechanism. Background Art

[0002] The radar housing is a key component in the radar system. Its design aims to protect the internal equipment of the radar from the external environment. This kind of housing is usually made of metal materials such as aluminum or steel to provide the necessary mechanical strength and corrosion resistance. The shape of the radar housing is usually cylindrical or spherical, which helps to reduce the scattering and reflection of radar signals, thereby reducing the impact on radar performance. In military applications, the radar housing may also have a stealth design to reduce the reflection characteristics of radar signals, thereby reducing the possibility of being detected. In summary, the radar housing plays a crucial role in the radar system, not only protecting the internal equipment, but also affecting the performance and concealment performance of the radar system.

[0003] Testing the impact resistance of metal sheets is a key material property assessment, aiming to comprehensively understand the behavior and response of materials when facing sudden and high-intensity external forces (i.e., impacts). This test is extremely important for ensuring the safety and reliability of metal products in practical applications. It not only evaluates the toughness of the material - the ability to resist fracture, especially in the presence of notches or defects, but also examines the quality of the material, revealing possible metallurgical defects such as inclusions, cracks, and non-metallic inclusions through energy absorption capacity and fracture analysis. In addition, the test verifies the effect of heat treatment to ensure that no additional brittleness is introduced, while evaluating the change in brittleness of the material under extreme temperature conditions, which is particularly important for materials operating at low or high temperatures to prevent failure due to increased brittleness caused by temperature.

[0004] Reference can be made to the patent with the publication number CN220729912U. This patent discloses an impact resistance testing device for a housing, including a testing cabinet. A wire releasing mechanism is fixedly connected to the top of the testing cabinet, and one end of the wire releasing mechanism penetrates into the interior of the testing cabinet and is fixedly connected to a counterweight mechanism. A clamping mechanism is slidably connected inside the testing cabinet, and a limiting mechanism is fixedly connected to one side of the testing cabinet. The wire releasing mechanism includes a wire releasing box, which is fixedly connected to the top end of the testing cabinet. A wire releasing roller is rotatably connected inside the wire releasing box. A rope is wound around the outside of the wire releasing roller, and the bottom of the rope penetrates above the testing cabinet. The bottom end of the rope is fixedly connected above the counterweight mechanism. This impact resistance testing device for the housing has advantages such as being able to automatically impact the housing.

[0005] Although this patent has an effect on the impact test of the outer shell, during the test, it can only test the impact resistance of the outer shell when it is placed flat, and it does not have the function of testing the impact resistance of the outer shell at different angles, so it is impossible to conduct a comprehensive test on the outer shell. Therefore, the inventor of the present invention proposes an impact resistance test mechanism for the radar outer shell to solve the above-mentioned technical problems. Summary of the Utility Model
