Patent ID: 7509850

Claim:
A vehicle protection device comprising: an inflation valve mounted on a wheel rim of a tire; a wiper externally mounted on the wheel rim as fastened by the inflation valve; and a sensor holder engaged with the inflation valve and positioned inside the wheel rim for holding a tire pressure sensor within the wheel rim and within the tire; whereby the sensor will sense the tire pressure for safely monitoring the tire pressure; and the wiper will scrape the rain water outwardly from the wheel rim for enhancing driving safety; and said inflation valve including: a connector having a female-threaded hole formed in the connector, a packing sleeve jacketed on the connector and fixed in a connector hole formed through the wheel rim for firmly mounting the connector in the wheel rim, and a retainer disk circumferentially integrally formed on the connector for fastening the wiper on the wheel rim; said wiper including: a base having a through hole formed in the base and engaged with the packing sleeve of the inflation valve to be fastened to the wheel rim by the retainer disk to firmly retain the wiper on the wheel rim, a scraper protruding from the base towards an axis of the wheel rim for scraping rain water or snow accumulated in an annular groove as recessed in the wheel rim, and a taper portion tapered outwardly from the scraper for thrusting the water outwardly from the wheel rim for enhancing driving safety; and said sensor holder including: a male-threaded screw portion having an inflating hole longitudinally formed through the screw portion and engaged with said female-threaded hole formed in the inflation valve for securing the sensor holder to an inside wall of the wheel rim within the tire, a nut circumferentially formed with the screw portion to be retained on the inside wall of the wheel rim as packed by a packing member, a fastening ring integrally formed on the nut for fastening a sensor holding portion of the tire pressure sensor, and an air opening formed through the fastening ring and fluidically communicated with the inflating hole and communicated with the inflation valve for directing air from the inflation valve into an interior in the tire and within the wheel rim for sensing the tire pressure by the sensor.
