Problems solved by technology

However, when the vehicle passes above the geomagnetic vehicle detector, it will generate a horizontal forward impact and downward pressure on the geomagnetic vehicle detector, which will deform the joint between the shell and the outer cover, thereby causing seal failure and water seepage. This is also verified by the event of damage to the printed circuit board assembly (PCBA, printed circuit board assembly) of the detector due to water leakage of the geomagnetic vehicle detector. It can be seen that the aforementioned sealing structure cannot meet the waterproof requirements of the geomagnetic vehicle detector
