Anechoic chamber with wave-absorbing pyramid for testing automobile controller

Abstract

The invention discloses an anechoic chamber with a wave-absorbing pyramid for testing an automobile controller, which comprises an anechoic chamber body, a chamber door, the wave-absorbing pyramid, a support, a rotating mechanism, a clamping mechanism, an anti-loosening mechanism and an automobile controller body, the chamber door is hinged to the anechoic chamber body, the wave-absorbing pyramid is arranged in the anechoic chamber body, and the support is hinged to the anechoic chamber body. The anechoic chamber comprises an anechoic chamber body, two supports are fixedly connected in the anechoic chamber body, the two supports are symmetrically distributed in the anechoic chamber body, the upper ends of the two supports are jointly provided with a rotating mechanism, the rotating mechanism is provided with a clamping mechanism, the clamping mechanism is provided with an anti-loosening mechanism, and the anti-loosening mechanism is provided with an anti-loosening mechanism. And an automobile controller body is clamped on the clamping mechanism. The invention relates to an anechoic chamber with a wave-absorbing pyramid for testing an automobile controller. The anechoic chamber has the characteristics of rotatable testing, good clamping applicability and stable testing process.

Description

technical field [0001] The invention belongs to the technical field of an anechoic chamber, in particular to an anechoic chamber with a wave-absorbing pyramid used for testing automobile controllers. Background technique [0002] Anechoic chamber Generally, for radiation experiments, there are three types of test sites, namely full anechoic chamber, semi-anechoic chamber and open field. The radiation tests carried out in these three test sites can generally be considered to conform to the law of electromagnetic wave propagation in free space. In the fully anechoic chamber, the absorbing pyramid needs to be arranged, which can effectively absorb the incident electromagnetic wave energy and greatly attenuate its scattering. At present, the test of the car controller needs to be carried out in the anechoic chamber. The car controller is mainly placed in the anechoic chamber through the fixture, but the car controller is in a static state during the test, which is not conducive...

AI Technical Summary

Problems solved by technology

At present, the test of the car controller needs to be carried out in the anechoic chamber. The car controller is mainly placed in the anechoic chamber through the fixture, but the car controller is in a static state during the test, which is not conducive to better testing it, and The fixture applicability of the car controller is poor
