Problems solved by technology

However, since all the sensor devices are equipped with antennas printed on the printed circuit board as described above, there is a problem that if the printed circuit board is arranged in parallel with the groove portion, the signal transmission efficiency will be very poor.
Therefore, the current situation is that the sensor is installed in such a way that the circuit board is upright with respect to the groove portion of the rim, and correspondingly, the rim assembly workability is reduced.
In addition, although a sensor device in which an antenna for information transmission is protruded to the outside of the casing has also been proposed, this also inevitably reduces the workability of rim assembly (for example, refer to JP-10-504783 A).

Embodiment Construction

[0025] Hereinafter, the configuration of the present invention will be described in detail with reference to the drawings.

[0026] Figure 1~ image 3 shows the tire sensor device formed by the first embodiment of the present invention, Figure 4 is an illustration of the sensor unit. As shown in FIG. 1 , the sensor device for a tire according to this embodiment detects internal information of the tire while being arranged in a tire air chamber, for example, on the groove portion W of the rim, and transmits the detection result to the outside. sensor devices; such as figure 2 and image 3 As shown, it includes a housing 1 for accommodating electronic components and an antenna 2 protruding from the housing 1 .

[0027] In the interior of the housing 1, it is stored as Figure 4 A sensor unit 10 as shown. This sensor unit 10 is a unit in which electronic components such as a sensor 12 , an information transmitter 13 , a battery 14 , and a control circuit 15 are mounted on ...

Abstract

A sensor device for a tire, having enhanced transmission capability without disturbing the assembly of a rim to the tire. With itself installed in the tire, the sensor device detects information inside the tire and transmits the result to the outside. The sensor device has a case for receiving an electronic component and an antenna electrically connected to the electronic component and extended to the outside of the case. The fore-end portion of the antenna is made to be displaceable to radially outside the tire by centrifugal force generated in the rotation of the tire.

Description

technical field [0001] The present invention relates to a tire sensor device for detecting tire internal information such as internal air pressure, and more specifically, to a tire sensor device with improved information transmission capability without hindering the rim assembly operation of the tire. Background technique [0002] In the past, in order to monitor tire internal information such as internal air pressure and temperature, the following operations were usually carried out: installing a sensor device on the well of the rim, using the sensor device to detect the internal information of the tire, and sending the detection result to the Receiver on the outside of the tire. [0003] In such sensor devices for tires, sensors and information transmitters are generally mounted on a printed circuit board, an antenna for information transmission is printed on the printed circuit board, and these sensors and information transmitters are stored together with the printed circ...
