01Car camera

car cameraIt is used to record the road conditions in front or behind during driving.Video equipment。
It mainly includes inside-view cameras, rear-view cameras, front-facing cameras, side-view cameras, surround-view cameras, etc.HeadThe front car camera is mainly used for reversing images (rear view) and360 degree panorama (look around) forDriver-assisted parking、Trigger emergency brakeandAutonomous drivingWaiting for the driving scene.At the same time, when an accident occurs, the video recorded by the on-board camera can be used as evidence of the party responsible for the accident.Judgment basis。

If the air tightness of the car camera is not tested, it is very easy for water vapor to enter under special weather (such as rain, snow, fog, etc.) and damage the internal chip; it may also form on the lens.water mist, affecting image quality, camera effects and driving safety.

This time we are going to configure a car camera that can testIP68Waterproof levelofAir tightness detector。

As can be seen from the appearance, this model needs to beAir tightness testThe camera does not have any inflation port, but has a wire at the end. This wire does not require air tightness testing.

So we designed this car cameraCustomizedTest the mold and useIndirect detectionAt the same time, a wire trough is reserved on the mold, and the wire is placed outside the mold.As shown below:

03Car cameras start air tightness testing

Parameter settings: According to product waterproof requirements andIP68grade waterproof grade, the pressure is set to60kpa, intake time5s,Stabilization time10s, test time5s。

The maximum value allowed for leakage is0.05kpa ,Equivalent to50pa。

After placing the camera into the mold, start the instrument, run the program, and the pressure sensor starts to work. After calculation, the gas leakage value is obtained, and the instrument automatically determines whether the product is qualified.UnqualifiedAt onceCall the police。
