Abstract

A touch-control tire pressure sensor device includes a housing holding an air nozzle at one side thereof, a circuit board accommodated in the housing and carrying a processor and memory unit having electrically coupled thereto a pressure sensor unit, a temperature sensor unit, an acceleration sensor unit, a LF transmission interface and a RF transmission interface for transmitting a sensed signal to an on-vehicle main unit, a battery pack providing the circuit board with the necessary working voltage, and a conducting plate having one end connected to the touch sensor IC and an opposite end kept in contact with the air nozzle.

Claims

1. A touch-control tire pressure sensor device, comprising the steps of:

a housing comprising an air nozzle located at one side thereof;

a circuit board comprising a processor and memory unit, a pressure sensor unit electrically coupled to said processor and memory unit and adapted to sense the pressure level of a vehicle tire, a temperature sensor unit electrically coupled to said processor and memory unit and adapted to sense the temperature of said vehicle tire, an acceleration sensor unit electrically coupled to said processor and memory unit and adapted to sense the acceleration value of said vehicle tire, a LF (low frequency) transmission interface and a RF (radio frequency) transmission interface respectively and electrically coupled to said processor and memory unit and adapted to transmit a sensed data to an on-vehicle receiver by a low frequency or radio frequency, and a touch control IC electrically coupled to said processor and memory unit;

a battery pack electrically coupled to said processor and memory unit and adapted to provide the touch-control tire pressure sensor device with the necessary working power supply; and

a conducting plate having a first end thereof electrically connected to said touch control IC of said circuit board and an opposing second end thereof kept in contact with said air nozzle electrically.

2. The touch-control tire pressure sensor device as claimed in claim 1, wherein said conducting plate comprises a through hole at the second end thereof.

3. The touch-control tire pressure sensor device as claimed in claim 2, wherein said housing comprises a holder block located at one side thereof, said holder block comprising a transverse through hole;

said air nozzle is accommodated in said holder block of said housing.

4. The touch-control tire pressure sensor device as claimed in claim 3, further comprising a screw bolt inserted through said transverse through hole of said holder block and the through hole of said conducting plate to fasten said conducting plate, said air nozzle and said housing together.

5. The touch-control tire pressure sensor device as claimed in claim 3, wherein said holder block comprising a longitudinal through hole;

said air nozzle is accommodated in said holder block of said housing;

the touch-control tire pressure sensor device further comprises a screw bolt inserted through said longitudinal through hole of said holder block and the through hole of said conducting plate to fasten said conducting plate, said air nozzle and said housing together.

6. The touch-control tire pressure sensor device as claimed in claim 5, wherein said conducting plate is a substantially L-shaped member comprising a longitudinal end electrically connected to said touch sensor IC of said circuit board, a transverse end extended from said longitudinal end and inserted into said air nozzle, and a through hole located at said transverse end for the passing of said screw bolt to fasten said conducting plate, said air nozzle and said housing together.

7. The touch-control tire pressure sensor device as claimed in claim 1, wherein said touch sensor IC is incorporated into said processor and memory unit.
