Abstract

The invention is applicable to the technical field of automobiles and provides an automobile chassis abnormal sound detection device. The automobile chassis abnormal sound detection device comprises abottom plate and detection equipment, wherein a vertical plate is fixed to the bottom plate, a top plate is arranged at the top of the vertical plate, a transverse rod is arranged on the vertical plate in a sliding mode, a first wheel seat and a second wheel seat are arranged at two ends of the transverse rod respectively, guide wheels are installed on the first wheel seat and the second wheel seat respectively, a locking assembly is arranged on the bottom plate, a first lifting rod and a second lifting rod are arranged on the top plate in a sliding mode, a transverse plate is installed at top ends of the first lifting rod and the second lifting rod, a microphone is installed on the transverse plate, and a lifting assembly is arranged on the top plate. The automobile chassis abnormal sound detection device is advantaged in that the guide wheel on the first wheel seat or the second wheel seat abuts against a side wall of the maintenance channel by moving the cross rod, the cross rod islocked and pushed by screwing the bolt, the guide wheel can roll along the side wall of the maintenance channel, and the device moves linearly so that the automobile chassis can be detected.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to an abnormal sound detection device of an automobile chassis. Background technique [0002] A Chinese patent with the authorized notification number CN209992188U discloses a vehicle chassis abnormal sound detection device, including: a mobile platform, which can drive the vehicle chassis abnormal sound detection device to move; Plate; testing equipment layout platform, extending along the horizontal direction, used to arrange testing equipment for detecting abnormal noise of the automobile chassis, the testing equipment layout platform is installed on the lifting plate and can rise and fall with the lifting plate, and the testing equipment layout platform is installed on the lifting plate The upper position is adjustable relative to the lifting plate. The detection process is simple to operate, the detection efficiency is high, and the safety is also greatly impro...
