AI Technical Summary

Technical Problem

In large anechoic chambers, turntables can cause material collisions, displacements, or deformations during EMC testing due to the laying and cutting of absorbing materials. Furthermore, the laying and dismantling of these materials is time-consuming, labor-intensive, and inefficient.

Method used

The platform body is fixed and rolls in contact with the turntable through the rotation mechanism of the casters and the universal brake wheels. It is fixed to the ground outside the turntable using fasteners. The platform is raised to form a physical isolation space to prevent the wave-absorbing material from moving with the turntable. Modular assembly and low dielectric constant materials are used to reduce material usage.

Benefits of technology

This achieves stability of the absorbing material, avoids material collisions and displacement, reduces laying complexity, saves manpower and costs, and improves testing efficiency.

Abstract

This invention provides a platform for fixing absorbing material for an anechoic chamber turntable and an anechoic chamber. The platform includes a platform body, the upper surface of which is covered with absorbing material. A rotating device is installed at the bottom of the platform body. The platform body is mounted on the turntable and rolls in contact with the turntable via the rotating device. The outer edge of the platform body is fixed to the ground outside the turntable by fasteners. By elevating the absorbing platform, which creates a physically isolated space between the platform and the turntable, and with the rotating structure at the bottom of the platform and the fasteners at the outer edge, the absorbing material no longer moves with the turntable when it rotates, keeping it stationary. This completely avoids the problems of edge material collision, displacement, or deformation in traditional circular cutting solutions, significantly improving the ease of absorbing material installation.
