The sensor module is usually composed of a housing, a PCB assembly (including batteries, antennas, PCB boards, chips, etc.), a sealing gasket, etc. The tire pressure monitoring sensor is powered by the battery on the PCB assembly.

[0003] In the current tire pressure monitoring sensors, most batteries are connected to the PCB board by directly welding the battery pins to the PCB board, and the battery, chip and other hardware are welded on the PCB board to form a PCB assembly. The PCB assembly is then sealed in the shell by means of sealant or by laser welding the cover plate to the shell to seal the PCB assembly to achieve waterproof and dustproof properties of the PCB assembly and other hardware. Such a non-replaceable structural form of parts will cause the entire sensor product to be scrapped when the battery is out of power or damaged, and it needs to be replaced as a whole. In view of this, the utility model proposes a composite sensor module for a third-generation tire pressure monitoring system to solve the above problems. Utility Model Content
