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.

Claims

1. A dual-sectional monitor signal transmission module for Wireless Tire Pressure Monitoring Systems, the module comprising:

a module body and an air tap on one side thereof, said air tap being assembled and fixed in a hole of a tire rim;

wherein said module body and said air-tap are a dual-sectional piece allowing said air-tap to be fittingly snapped into the hole on the tire rim;

further comprising;

a mounting seat at an end of said module body where the air-tap is to be positioned so that the air-tap and an outer-end of the mounting seat can be connected in a counter-screw setup wherein the air tap is comprised of a flexible outer-sleeve and a metal tube, said outer-sleeve having on one end thereof a sunken-slot, which forms an external thread, protruding in a center of the sunken-slot at a same end of the metal tube, wherein said mounting seat is comprised of a step-shape cylindrical metal seat with a protruding tube at an outer end thereof having a threaded connection slot in a center thereof, an inner end of the mounting seat being a column-shape body, an outer side of a mid-section of the mounting seat forming a collared edge, and a slot being set at the air-tap end of the module body, wherein the mounting seat is orientable to snap into the slot of the module body through the column-shape body at the internal end and positioned by stopping the collared edge at the external part of the module body; and

wherein the air-tap is fittable onto the protruding tube on the mounting seat through the sunken-slot, and the column-shape body is screwable onto the threaded connection slot on the protruding tube to achieve positioning of the air-tap on the module body.

2. The module defined in claim 1, wherein a fitting part at the outer rim of a sir-tap is comprised of two spaced wedges;

wherein, through the slot formed by the two wedges, the module body is snappable into the hole on the tire-rim to achieve air-tight connection.
