Automobile fault diagnosis assembly

Abstract

The invention relates to an automobile fault diagnosis assembly, and belongs to the technical field of mobile equipment fault inspection, and the assembly comprises: a pipe body, wherein the two sides of a pipeline of the pipe body are provided with pipe openings; an adjusting plate, wherein the adjusting plate is movably arranged at the position of the pipe orifice on one side; a driving part, wherein the driving part is installed on the outer wall of the pipe body, the driving part and the adjusting plate are assembled, and the driving part drives the adjusting plate to move at the position of the pipe opening, so that the size of the opening at the position of the pipe opening is adjusted; a connecting plate, wherein the connecting plate is assembled on the pipe body; and an impact sensor, wherein the impact sensor is installed on the connecting plate, the input end of the impact sensor is right opposite to the pipe opening position of the pipe body, and the impact sensor is in signal connection with external terminal equipment. In order to detect automobile faults more safely and timely in the automobile using process, the automobile fault diagnosis assembly can detect the automobile faults through exhaust impact of an exhaust tail pipe.

Description

technical field [0001] The present application relates to the field of fault checking of mobile devices, and in particular to automotive fault diagnosis components. Background technique [0002] The rapid development of the contemporary economy has led to the rapid development of the transportation industry, and the automobile has become one of the most important and popular means of transportation in the world. [0003] The automobile exhaust system mainly discharges the exhaust gas from the engine, and at the same time reduces the pollution of the exhaust gas and reduces the noise. Automobile exhaust systems are mainly used in light vehicles, mini-cars, passenger cars, motorcycles and other motor vehicles. An automobile exhaust system refers to a system that collects and emits exhaust gas, and generally consists of an exhaust manifold, an exhaust pipe, a catalytic converter, an exhaust temperature sensor, an automobile muffler, and an exhaust tailpipe.

AI Technical Summary

Problems solved by technology

[0005] However, automobile power faults cannot be judged solely by visual and auditory effects. For example, when the exhaust pipe is blocked but not completely blocked, the fault sound is very small and the exhaust effect is not obvious. When the failure of the car cannot be judged, the car owner will often continue to drive, and accidents may occur during the driving process, causing danger.
