Description

Technical Field

[0001] This utility model relates to the field of automotive oxygen sensor technology, specifically to an automotive oxygen sensor that can prevent it from falling off due to vibration. Background Technology

[0002] The automotive oxygen sensor is a key feedback sensor in the electronic fuel injection engine control system. It is a crucial component for controlling vehicle exhaust emissions, reducing vehicle pollution, and improving the quality of fuel combustion in automotive engines. Oxygen sensors are all installed on the engine exhaust pipe.

[0003] However, the inventors believe that current automotive oxygen sensors on the market have the following drawbacks: In practical applications, most oxygen sensors are threaded to the exhaust pipe mounting location using a threaded connection. Over time, the engine exhaust pipe vibrates during vehicle operation, causing the oxygen sensor to loosen and fall off, resulting in an unstable position and affecting the installation stability of the oxygen sensor. Therefore, we have proposed an automotive oxygen sensor that can avoid vibration-induced detachment to solve the above-mentioned problems. Utility Model Content

The inner wall of the insertion hole is slidably connected to the surface of the U-shaped rod. The U-shaped rod is provided to facilitate the limiting of the screw tube on the stop block during use, maintain the stability of the screw tube, and prevent the screw tube from loosening.

[0012] Preferably, an arc-shaped magnetic block is fixedly installed at one of the corners of the U-shaped rod. The arc of the arc-shaped magnetic block matches the surface arc of the stop block, and the arc-shaped magnetic block and the surface of the stop block are magnetically attracted. The arc-shaped magnetic block can make the U-shaped rod stably connected to the stop block during use, and prevent the U-shaped rod from separating from the stop block.
