Abstract

Provided is a container structure for attaching sensors to tires and, more particularly, to a container structure for attaching sensors to tires, the container structure being able to prevent sensors attached to tires from being damaged by intense heat. The container structure can include: a bottom container that is attached to the inner liner of a tire; a top container that extends from the top of the bottom container and has an insertion space in which a sensor can be inserted; and a channel part that is formed on the inner side of the top container, in which the channel part is provided such that air can cool the sensor by flowing inside and outside with the sensor inserted in the top container.

First claim

What is claimed is:

1. A container structure for attaching a sensor to a tire, the container structure comprising:
a bottom container configured to be attached to an inner liner of the tire;
a top container extending from a top of the bottom container and having an insertion space in which the sensor is to be disposed; and
a channel part formed on an inner surface of the top container,
wherein the channel part includes:
a plurality of entrances formed on an inner side of an upper end portion of the top container, each entrance being formed to be recessed from an inner circumference of the upper end portion of the top container; and
a plurality of internal channels extending from the plurality of entrances along an inner lateral surface and an inner base surface of the top container to connect the plurality of entrances to each other,
wherein at least two of the plurality of internal channels intersects each other on the bottom of the top container, and
wherein the plurality of internal channels are recessed on the inner lateral surface and the inner base surface of the top container.

2. The container structure of claim 1 , wherein the bottom container is formed in a disc shape or a polygonal shape.

3. The container structure of claim 1 , wherein the top container has an open top.

4. The container structure of claim 1 , wherein the channel part further includes a cooling hole formed through the bottom of the top container and the bottom container, and
wherein the cooling hole is connected to the plurality of internal channels such that air flowing inside the container structure through the plurality of entrances cools the inner liner.

5. A method of manufacturing a container structure, the method comprising:
a) preparing a vulcanized tire; and
b) forming a container structure by injecting or compressing non-vulcanized rubber to an inner liner of the vulcanized tire,
wherein in the step b), the container structure includes:
a bottom container configured to be attached to the inner liner of the vulcanized tire;
a top container extending from a top of the bottom container and having an insertion space in which a sensor is to be disposed; and
a channel part formed on an inner surface of the top container,
wherein the channel part includes:
a plurality of entrances formed on an inner side of an upper end portion of the top container, each entrance being formed to be recessed from an inner circumference of the upper end portion of the top container;
a plurality of internal channels extending from the plurality of entrances along an inner lateral surface and an inner base surface of the top container to connect the plurality of entrances to each other; and
a cooling hole formed through the bottom of the top container and the bottom container, and
wherein the cooling hole is connected to the plurality of internal channels such that air flowing inside the container structure through the plurality of entrances cools the inner liner, and
wherein the plurality of internal channels are recessed on the inner lateral surface and the inner base surface of the top container.

6. The method of claim 5 , wherein the non-vulcanized rubber is a material applied in the inner liner or is a crosslinkable-bonded elastomer composite to improve interface attachment between the inner liner and the container structure.

7. The method of claim 5 , further comprising pre-processing the vulcanized tire after the step a),
wherein in the pre-processing, a portion where the container structure is formed on the inner liner is cleaned.

8. The method of claim 7 , wherein the pre-processing is performed using a solvent including any one of naphtha, n-nucleic acid, toluene, and ethane with one or more or maximally four Cl substituted for H.

9. The method of claim 7 , wherein the pre-processing is performed by at least one of plasma surface processing, corona surface processing, and laser cleaning.

10. The method of claim 5 , wherein in the step b), the container structure is formed by injecting and compressing the non-vulcanized rubber with the sensor placed in a mold having a shape of the container structure.
