Abstract

The invention provides a durability testing device for an automobile oxygen sensor, belongs to the technical field of oxygen sensors, aims to solve the problem that detection under different conditions cannot be realized through structural improvement, the problem that after-treatment cannot be achieved to improve an environmental protection effect, and the problem that full contact between tail gas and filtered liquid cannot be achieved through structural improvement to improve a filtering effect. The durability testing device for the automobile oxygen sensor comprises a base; and a sliding structure is mounted on the base, and a mounting seat structure is fixedly connected to the base through bolts. As the number of extrusion arms is two, the two extrusion arms are both welded to the sliding block; when the sliding block is located at an initial position, the two extrusion arms make elastic contact with a gas cylinder, and therefore when the two extrusion arms reciprocate along with the sliding block, continuous collision of the gas cylinder can be achieved, impact type gas injection is achieved, and finally the comprehensiveness of detection is improved.

Description

technical field [0001] The invention belongs to the technical field of oxygen sensors, and more specifically relates to an automobile oxygen sensor durability testing device. Background technique [0002] Automobile oxygen sensor is a key sensing component in the engine control system, and is a key part to control automobile exhaust emissions, reduce automobile environmental pollution, and improve the fuel combustion quality of automobile engines. Durability test is a test to determine the service life of the oxygen sensor under specified use and maintenance conditions, and to predict or verify the weak links and dangerous parts of the structure. [0003] For example, the application number: CN201910118973.8, the present invention relates to a durability test device for an oxygen sensor for automobiles, including a frame, a display stand set above the frame, a cavity set in the frame, and a An oxygen sensor environment simulation test system, a drive system that drives the ...
