01 Car camera

车载摄像头It is used to record the road conditions ahead or behind during the driving processrecording equipment.
Mainly including internal view camera, rear view camera, front view camera, side view camera, surround view camera, etc.eyeThe front car camera is mainly used for reversing image (rearview) and360 degree panoramic view (surround view), used forAssist the driver in parking、Trigger emergency brakeandautonomous drivingWaiting for the driving scene. At the same time, in the event of an accident, the video recorded by the onboard camera can serve as the responsibility of the party responsible for the accidentbasis for determination.

If the car camera is not tested for air tightness, it is very easy for water vapor to enter and damage the internal chip in special weather conditions (such as rain, snow, heavy fog, etc.); It may also form on the lenswater mistAffects image quality, camera performance, and driving safety.

02 Car camera气密性检测preparation

This time we need to equip this car camera with a testing deviceIP68waterproof ratingof气密性检测仪.

From the appearance, it can be seen that this product needs to be madeairtightness testThe camera does not have any inflation port, and there is a wire at the end that does not require air tightness testing.

So we designed this car camera forCustomizedTesting molds, usingIndirect detectionAt the same time, reserve a wire slot on the mold and place the wire outside the mold. As shown in the following figure:

03 Car camera begins air tightness testing

Parameter setting: According to the waterproof requirements of the product andIP68Waterproof grade, pressure set to60kpa, intake time5s,voltage stabilization time10sTesting time5s.

The maximum allowable leakage value is0.05kpa ,equivalent to50pa.

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