Abstract: A dual-sectional monitor signal transmission module for Wireless Tire Pressure Monitoring Systems. On one side of this monitor signal transmission module, an air tap is designed, which can be assembled and fixed in the hole of the tire rim. This Monitor Signal Transmission Module and the air-tap are a dual-sectional combination to allow the air-tap to be fittingly snapped into the hole on the tire rim. Moreover, a mounting seat is designed on the Monitor Signal Transmission Module at the end where the air-tap is to be positioned so that the air-tap and the outer-end of the mounting seat can be connected in a counter-screw setup. The Monitor Signal Transmission Module can be easily detached with just a simple step of unscrewing the air-tap when replacing tires.

Abstract: A shell structure for Wireless Tire Pressure Transmission Devices. The internal part of this shell is a space provided for installation of a Wireless Tire Pressure Transmission Device and the bottom part of the shell is a fixture dimension which enables attachment of the Wireless Tire Pressure Transmission Device onto the surface of the tire-rim. On the two ends of the shell, wire-holes are designed to provide for wire-fixing. The fixture dimension on the bottom of the shell, viewed from the cross-section, is designed in a slanting dimension. Or, the wire-holes of the shell can be designed to form a slanting angle to replace the above-stated slanting dimension of the shell-fixing surface.
