Transmission device for transmitting information about tire condition and tire condition monitoring system
First Claim
1. A transmitting device provided in a tire cavity area to transmit tire information about a condition of a tire, the transmitting device comprising:
- a sensor configured to detect, as the tire information, a condition of gas filled in the tire cavity area surrounded with the tire and a rim;
a transmitter configured to wirelessly transmit the detected tire information; and
a housing which has a wall surrounding the sensor and the transmitter, such that an inner space is separated from the tire cavity area by the wall, the housing defining a plurality of through holes passing through the wall, the through holes including a communicating through hole which enables communication between the tire cavity area and the inner space in the housing and a selectively non-communicating through hole having a member which is movable between a blocking position which impedes communication between the tire cavity area and the inner space in the housing through the selectively non-communicating through hole and an unblocking position which enables communication between the tire cavity area and the inner space in the housing through the selectively non-communicating through hole.

Abstract
A tire condition monitoring system includes a transmission device, a receiving device, and a monitoring section. The transmitting device includes a sensor which detects, as tire information, a condition of gas in the tire cavity area surrounded with a tire and a rim, a transmitter which wirelessly transmits the tire information, and a housing having a wall surrounding the sensor and the transmitter and separating an inner space from the tire cavity area. The housing wall defines a communicating through hole which enables communication between the cavity area and inner space and a selectively non-communicating through hole having a member which is movable between blocking and unblocking positions to impede and enable communication, respectively, between the cavity area and inner space. The receiving device receives the tire information, and the monitoring section determines whether a tire anomaly exists based on the tire information and provides a result.

16. A transmitting device provided in a tire cavity area to transmit tire information about a condition of a tire, the transmitting device comprising:
-
a sensor configured to detect, as the tire information, a condition of gas filled in the tire cavity area surrounded with the tire and a rim; a transmitter configured to wirelessly transmit the detected tire information; and a housing which has a wall surrounding the sensor and the transmitter, such that an inner space is separated from the tire cavity area by the wall, the housing defining at least one through hole passing through the wall of the housing to communicatively connect the inner space and the tire cavity area, and the housing further including a removable protrusion which protrudes from a face of the housing and a thin-walled portion which is formed in a position corresponding to a position of the protrusion on an opposite side of the wall of the housing from the protrusion and has a smaller wall thickness than a portion around the thin-walled portion, such that a new through hole is formed at the position of the thin-walled portion by removing the protrusion. - View Dependent Claims (18)
