Embodiment Construction

[0020] In particular, like reference numerals are shown in the figures to indicate identical or similar parts in each of the several views. figure 1 A tire pressure monitor 10 is described, configured to be movable inside the tire (either inside a tubeless tire or inside the inner tube of a tubed tyre), i.e. the sensor 10 need not be fixedly fitted to the edge of the tire or any part of the tire itself at a single location.

[0021] The sensor 10 includes a housing 20, such as figure 1 Shown are two parts of the housing fastened together by fasteners 22 . The fastener 22 is shown as a threaded fastener with a lock 24 . However, it should be understood that the portioning of the enclosure is not critical and that the enclosure is shown for ease of assembly, other configurations such as those with an opening at one end by a snap-hinged door, or any other configuration that allows insertion of components into the enclosure may For sensor 10.

[0022] Housing 20 includes at le...

Abstract

The invention relates to a tire pressure monitoring system without requirement of assembly. According to the system, a tire pressure monitoring sensor capable of movement inside the tire comprises a housing, wherein a pressure sensing/sending unit, one or a plurality of batteries, and an antenna for sending a signal of an internal tire pressure instruction are accommodated in the housing. In one embodiment, components are assembled inside the housing, such that the centre of gravity and the geometric center of the housing are the same. During the tire rotation process, a monitor independently rotates inside the tire, and is particularly applicable for the tire with the characteristic of slow rotation, such as a tire used in a gantry system. Optionally the pressure monitoring components are assembled inside the housing, such that the centre of gravity deviates the geometric center of the housing. With the centripetal force generated during the tire rotation process, the monitor and the tire rotate together, and the monitor is applicable for the tire with the characteristic of rapid rotation, such as an automobile tire. The tire pressure monitoring system comprises the monitor and a receiver, wherein the receiver is positioned outside the tire, and is provided for receiving the monitoring signal.

Description

technical field [0001] The present invention relates to a tire pressure monitoring system, and more particularly to a tire pressure monitoring system that can move freely in a tire or an inner tube. Background technique [0002] Vehicles equipped with pneumatic tires require more scrutiny because more detailed information about tire pressure is required. Since underinflated vehicle tires will cause increased fuel consumption compared to properly inflated tires, such tire pressure information is required for safe operation of the vehicle and better fuel efficiency (in the case of motor vehicles). Various systems have been proposed for monitoring tire air pressure. Typically, tire pressure monitoring systems include a pressure monitor and components that can transmit tire pressure information, typically in the form of a radio frequency (RF) signal, to a receiver. Such receivers may be located within a monitoring station (for tire-based machines such as the rack system of rub...
