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. The water leakage of the geomagnetic vehicle detector caused damage to the printed circuit board assembly (PCBA, printed circuit board assembly) of the detector, which also verified this point. It can be seen that the aforementioned sealing structure cannot meet the waterproof requirements of the geomagnetic vehicle detector

Embodiment Construction

[0033] The basic idea of ​​the present invention is: adopt double-layer sealing cavity to seal PCBA and battery, greatly improve the waterproof performance, and the outer sealing cavity surrounds the inner sealing cavity, so as to protect the welding place inside the inner cover and the side wall from the impact of vehicle rolling The impact of force and pressure further improves the waterproof performance; only the upper end of the inner shell is surrounded by the side wall of the outer shell with a cylindrical ring shape. On the one hand, the cylindrical outer shell reduces the impact force of the shell when it is rolled by a vehicle , that is, it reduces the possibility of damage to the shell by the impact force when the vehicle is rolled, and enhances the impact resistance of the relatively weak part of the shell, that is, enhances the impact resistance of the entire shell. On the other hand, it avoids the occurrence of geomagnetic vehicle detection Rotation during installa...

Abstract

The invention relates to a geomagnetic vehicle detector which specifically comprises a PCBA, a battery, a support and a shell, wherein the shell comprises a shell body and a shell cover, the shell body comprises an inner shell body and an outer shell body, the inner shell body is a square shell body, and the side wall of the outer shell body is a cylindrical ring which encloses the upper end of the inner shell body; the top part of the inner shell body is lower than the top part of the outer shell body, and the bottom face of the outer shell body is connected to the bottom end of the side wall of the outer shell body and the side wall of the inner shell body; the shell cover comprises an inner cover and an outer cover; the bottom face edge of the inner cover and the side wall top face of the inner shell body are welded to form an inner sealing chamber, and the support fixes the PCBA and the battery inside the inner sealing chamber; and the bottom face edge of the outer cover and the side wall top face of the outer shell body are welded to from an outer sealing chamber. The geomagnetic vehicle detector provided by the invention can improve waterproof performance and detection accuracy of the geomagnetic vehicle detector as well as impact resistance of the shell body.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a geomagnetic vehicle detector. Background technique [0002] Intelligent Transportation System (ITS, Intelligent Transportation System) effectively integrates advanced information technology, data communication transmission technology, electronic sensing technology, control technology and computer technology into the entire ground traffic management system, which can Play the role of real-time, accurate and efficient comprehensive transportation management. Comprehensive transportation management specifically includes public transportation management, commercial vehicle operation management, travel demand management, traffic emergency management, vehicle control and safety management, etc., and the vehicle detection system is the data basis for ITS to realize comprehensive transportation management. [0003] Vehicle detection systems are divided into two categories acc...
