Description

  The present invention relates to a functional component mounting apparatus for mounting a functional component on an inner surface of a tire.

For example, as shown in FIG. 12, a functional component 290 such as a sensor module in which a sensor (a pressure sensor, a temperature sensor, an acceleration sensor, etc.), a battery or a power generating element, and a radio is integrated is used as a rubber functional component mounting member. In the technology for detecting the state of the tire by mounting it on the inner surface 70 of the tire 60 via the functional component mounting base 100, the functional component side mounted portion provided on the functional component 290 as the functional component mounting base 100 The thing of the structure provided with the attaching part 200 with the recessed part 200A to which 300 is attached in a fitting state is known (refer patent documents 1 and 2).
The vehicle tire rolls while the vehicle is running, with the lowermost part of the circumferential surface of the tire in contact with the ground, the non-grounding portion is rotating, and the grounding portion is linear. For this reason, the stepped-in end (FIG. 11), which is a boundary when a part of the circumferential surface of the tire 60 transitions from the non-grounding part to the grounding part, and a part of the circumferential surface of the tire 60 from the grounding part to the non-grounding part An unbalanced state of the centripetal forces F1 and F1 generated with the rotation of the tire 60 is generated at the kicking end which is a boundary at the time of transition to, and is attached to the inner surface 70 of the tire 60 via the functional component mounting base 100. An inertial force F2 is applied to the functional component 290 (see FIG. 11). This inertial force F2 increases as the rotational speed (vehicle speed) of the tire 60 increases, and may reach several tens of kgf. Therefore, the functional component mounting base 100 to which the functional component 290 is mounted is damaged, and the functional component mounting base. There is a possibility that the functional component 290 attached to 100 may fall off. In the drawing, R indicates the rotation direction (rolling direction) of the tire 60 during vehicle travel.

JP 2012-240603 A JP2015-160512A

In the conventional functional component mounting base that fixes the functional component only by rubber tension (rubber elasticity), the binding force (clamping force) on the functional component is weak, and the functional component mounting base is caused by the large inertia force generated at high speed running. There was a risk of damage.
In particular, a large amount of electric power is required to transmit the information obtained by sensors mounted on the functional parts mounted on the inner surface of the tire via the functional part mounting base to the vehicle side. There is a case where a power generator (generator) is provided separately, but in order to generate a large amount of power, a functional component equipped with a large and heavy power generator must be attached to the inner surface of the tire via a functional component mounting base. In the conventional functional component mounting base (functional component mounting member) in which the functional component is fixed only by rubber tension, the binding force on the functional component tends to be weak.
For example, when inertial force at the time of kicking is generated, the functional component 290 is attached to the inner surface 70 of the tire 60 via the conventional functional component mounting base 100 as shown in FIG. When inertial force F is generated in 290, the inertial force F is supported at only one place before and after the rotational direction (rolling direction) R of the tire 60, as indicated by the white arrow. The burden on the component mounting base 100 is increased, and the durability of the functional component mounting base (functional component mounting apparatus) 100 is deteriorated.
