Description
Technical Field
The invention belongs to the field of automobile part manufacturing, and particularly relates to a fixing structure of an automobile nitrogen-oxygen sensor with protection and wire harness straightening functions.
Background
In order to meet the increasingly stringent emission regulation requirements, diesel vehicles use nitrogen-oxygen sensors to monitor the content of nitrogen oxides in the exhaust gas, thereby determining whether the exhaust gas is out of compliance. Factors such as wire harness abrasion, water inflow, high temperature and vibration can cause damage to the nitrogen oxygen sensor, so that detection of emissions is influenced; and the nitrogen oxygen sensor is high in price, and if the nitrogen oxygen sensor is damaged, great economic loss is brought to users and the whole automobile factory.
Patent CN204328415U (published by 20150513) discloses a nitrogen oxygen sensor fixing bracket, but it does not design a structure for fixing a nitrogen oxygen sensor wire harness. In consideration of generalization, nitrogen oxide sensor suppliers generally adopt relatively long wiring harnesses (about 1 meter) to meet various arrangement environments, but an actual vehicle often does not need the wiring harness of 1 meter, and redundant wiring harnesses may be damaged due to interference with other components or vibration and other factors.
The heat insulation composite material and the heat insulation plate adopted in patent CN204328415U (published as 20150513) are both made of C304 stainless steel, and the heat insulation effect is poor.
