Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts production and testing, and in particular to an automobile air quality sensor testing stand. Background Art

[0002] As a primary means of transportation, cars bring convenience. However, while driving, harmful gases such as carbon monoxide and formaldehyde from vehicle exhaust or air conditioning systems may not be fully expelled, remaining inside the vehicle. These gases can seriously affect the health of occupants, necessitating monitoring of vehicle interior air quality. This requires the use of automotive air quality sensors. These sensors are crucial components for monitoring air quality inside vehicles. During production, automotive air quality sensors undergo testing to verify their conformity (e.g., carbon monoxide sensitivity testing).

[0003] Automotive air quality sensors are relatively small and sophisticated, requiring a demanding testing environment. Furthermore, they are crucial components of the vehicle interior and directly impact the health of passengers, making accurate testing essential. Currently, automated testing equipment is used, but further research is needed to determine how to effectively deliver various test gases to the air quality sensor. Summary of the Invention

[0004] The purpose of the present invention is to solve the above problems and provide an air quality sensor detection stand that is easy to operate, has no gas leakage, and is efficient, and can achieve effective transportation of the detection gas.

[0016] Furthermore, the telescopic sleeve mechanism is symmetrically arranged on both sides of the base and the cover plate.

[0017] Furthermore, the slot is a square slot, and the clamping block is a square block, which are fitted together in an interference fit manner.

[0018] During the specific test, take out the carrier plate, place multiple air quality sensors to be tested on the carrier plate one by one, and then place the carrier plate on the base. The carrier plate and the base are matched, and then the cover is covered. The air outlet on the cover is abutted against the gas detection interface of the air quality sensor to be tested, and the card block is inserted into the slot, which can firmly buckle the cover on the base and make the air outlet fit tightly on the air quality sensor to be tested. The test gas air, nitrogen dioxide, ammonia and carbon monoxide, etc. are introduced for testing.

[0019] Compared with the prior art, the lower surface of the cover of the device of the present invention is provided with an air supply channel, and the air supply channel is provided with a plurality of air outlets. The air outlets are arranged in one-to-one correspondence with the air quality sensors to be detected, and test gases can be introduced at the same time to meet the testing requirements of different gases; limiting frames are provided on both sides of the base, and a slot is provided in the middle of the limiting frames; cover side edges matching the limiting frames are provided on both sides of the cover, and a card block matching the slot is provided in the middle of the cover side edges.
