Abstract

The present invention concerns a vehicle tire pressure measurement unit 1 with a valve 5 and a fastening element 3 for arrangement of a tire pressure measurement device 7 on the valve 5, in which the fastening element 3 includes a first fastening area for snap connection with a second fastening area made in complementary fashion on the valve 5 in order to secure the fastening element 3 and valve 5 to each other.

Claims

1. Vehicle tire pressure measurement unit comprising

a valve, and

a fastening element for arrangement of a tire pressure measurement device on the valve, in which

the fastening element can include a first fastening area for snap connection with a second fastening area formed in complementary fashion on the valve to secure the fastening element and the valve to each other, and

the fastening element includes a receptacle for arrangement of the tire pressure measurement device in the fastening element, in which the receptacle of the fastening element includes an area that extends into the first fastening area.

2. Vehicle tire pressure measurement unit according to claim 1, in which at least the area of the receptacle of the fastening element that extends into the first fastening area is designed as a fluid guide.

3. Vehicle tire pressure measurement unit according to claim 1, in which the receptacle of the fastening element includes at least one thermally deformable area.

4. Vehicle tire pressure measurement unit according to claim 1, in which the first fastening area can be snapped into the second fastening area or in which the second fastening area can be snapped into the first fastening area.

5. Vehicle tire pressure measurement unit according to claim 1, in which the first fastening area includes at least one at least partially elastic area for the snap connection or in which the second fastening area includes at least one at least partially elastic area for the snap connection.

6. Vehicle tire pressure measurement unit according to claim 1, in which the fastening element includes at least one fluid passage opening.

7. Vehicle tire pressure measurement unit according to claim 1, including the tire pressure measurement device, in which the tire pressure measurement device is arranged by means of the fastening element and the tire pressure measurement device includes a power supply, pressure sensor and a circuit board or chip with a control device.

8. Vehicle tire pressure measurement unit according to claim 1, in which the tire pressure measurement device includes a communication unit for wireless transmission of pressure measurement signals.

9. Vehicle tire pressure measurement unit according to claim 8, in which the communication unit includes a protruding, elastically deformable antenna.

10. Vehicle tire pressure measurement unit according to claim 9, in which the antenna in the assembled state contacts a conducting area of the valve.

11. Vehicle tire pressure measurement unit according to claim 9, in which the antenna in the assembled state extends into the first fastening area.

12. Fastening element for arrangement of a tire pressure measurement device on a valve in a vehicle tire pressure measurement unit comprising

a first fastening area for snap connection with a second fastening area formed in complementary fashion on the valve to secure the fastening element in the valve to each other,

in which the fastening element includes a receptacle for arrangement of the tire pressure measurement device in the fastening element, and

in which the receptacle of the fastening element includes an area that extends into the first fastening area.

13. Valve for a vehicle tire pressure measurement unit, which includes a fastening element for arrangement of a tire pressure measurement device on the valve, with a fastening area for snap connection with a fastening area made in complementary fashion on the fastening element of the vehicle tire pressure measurement unit, to secure the fastening element and the valve to each other.
