Abstract

A wheel rim having a tire sensor for a pneumatic tire is disclosed. The wheel rim includes a rim portion having a valve rod, a base seat fixing on the rim portion at a location other than the location of the valve rod, and a sensor embedded in and attached to the base seat. The sensor is used for sensing the conditions of the pneumatic tire and transmitting the obtained signals by radio frequency.

Claims

1. A wheel rim having a tire sensor for a pneumatic tire comprising:

a rim portion having a valve rod;

a base seat fixing on the rim portion at a location other than the location of the valve rod, and

a sensor embedded in and attached to the base seat for sensing the conditions of the pneumatic tire and transmit the obtained signals by radio frequency.

2. The wheel rim having a tire sensor for a pneumatic tire of claim 1, wherein the base seat is in opposite position of the valve rod.

3. The wheel rim having a tire sensor for a pneumatic tire of claim 1, wherein the base seat comprises two fastening hooks for fastening the sensor.

4. The wheel rim having a tire sensor for a pneumatic tire of claim 3, wherein the base seat comprises two flaps for disassembling the sensors.

5. The wheel rim having a tire sensor for a pneumatic tire of claim 1, wherein the base seat comprises an upper lid portion to act together with the base seat for firmly fixing the sensor.

6. The wheel rim having a tire sensor for a pneumatic tire of claim 1, wherein the upper lid portion has a concave portion for tightly pressing the sensor downward when the upper lid portion acts together with the base seat.

7. A wheel rim having a tire sensor for a pneumatic tire comprising:

a rim portion having a valve rod; and

a sensor attached directly on the rim portion at a location other than the location of the valve rod for sensing the conditions of the pneumatic tire and transmit the signals obtained by radio frequency.

8. The wheel rim having a tire sensor for a pneumatic tire of claim 7, wherein the base seat is in opposite position of the valve rod.

9. The wheel rim having a tire sensor for a pneumatic tire of claim 7, wherein the rim portion has a concave portion for embedding the sensor therein.

10. The wheel rim having a tire sensor for a pneumatic tire of claim 7, wherein the base seat comprises two fastening hooks for fastening the sensor.

11. The wheel rim having a tire sensor for a pneumatic tire of claim 10, wherein the base seat comprises two flaps for disassembling the sensors.

12. The wheel rim having a tire sensor for a pneumatic tire of claim 7, wherein the base seat comprises an upper lid portion to act together with the base seat for firmly fixing the sensor.

13. The wheel rim having a tire sensor for a pneumatic tire of claim 12, wherein the upper lid portion has a concave portion for tightly pressing the sensor downward when the upper lid portion acts together with the base seat.
