A power generator having a piezoelectric element is disposed on one or both of the inner peripheral portions of the outer tubeless tire and the outer tubeless tire, and the power generator generates power by pressure contact between the inner tube and the outer tubeless tire. Is.
本発明は、簡単な構造で、タイヤの振動を電気に変換することができる。 The present invention can convert tire vibration into electricity with a simple structure.
以下に本発明の構成を添付した図面を参照して詳細に説明する。
図１は自動車の車体に取り付けられて使用される二重構造タイヤ（２）の断面図を示している。二重構造タイヤ（２）は、ホイール（４）に、内側チューブタイヤ（６）と外側チューブレスタイヤ（８）が取り付けられている。
Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 shows a cross-sectional view of a dual structure tire (2) used by being attached to the body of an automobile. In the dual structure tire (2), an inner tube tire (6) and an outer tubeless tire (8) are attached to a wheel (4).
タイヤ（２）は、外側チューブレスタイヤ（８）と内側チューブタイヤ（６）の二重構造となっている。内側チューブタイヤ（６）の外周面は、所定の間隔を存して外側チューブレスタイヤ（８）の内周面に対面配置されている。内側チューブタイヤ（６）の、サイドウォール部とほぼ直角な周壁部（６ａ）の外周部には、図７に示すように、電極（１０）（１２）と、ピエゾ素子と呼ばれる圧電素子（１４）とからなる発電体（１６）が全周にわたって一体的に固設されている。 The tire (2) has a double structure of an outer tubeless tire (8) and an inner tube tire (6). The outer peripheral surface of the inner tube tire (6) is arranged to face the inner peripheral surface of the outer tubeless tire (8) with a predetermined interval. As shown in FIG. 7, on the outer peripheral portion of the peripheral wall portion (6a) substantially perpendicular to the sidewall portion of the inner tube tire (6), as shown in FIG. ) Is integrally fixed over the entire circumference.
発電体（１６）は、内側チューブタイヤ（６）のゴム層（１８）と保護用のゴム部（２０）間に配置され、発電体（１６）の厚み方向の両面は対面するゴム部（２０）とベルトコード（２２）に接着されている。ベルトコード（２２）には、図７に示すようにプライコード層（２４）が接着され、プライコード層（２３）はゴム層（２０）に接着されている。 The power generation body (16) is disposed between the rubber layer (18) of the inner tube tire (6) and the protective rubber part (20), and both surfaces in the thickness direction of the power generation body (16) face each other. ) And the belt cord (22). As shown in FIG. 7, the ply cord layer (24) is bonded to the belt cord (22), and the ply cord layer (23) is bonded to the rubber layer (20).
図１中、（２４）は内側チューブタイヤ用バルブ、（２６）は外側チューブレスタイヤ用バルブ、 （２７）はエアーノズルである。発電体（１６）の電極（１０）（１２）は、ホイール（４）に配設された電気接点（図示省略）を通じて、タイヤ（２）の外部の電気配線と接続している。外側チューブレスタイヤ（８）と内側チューブタイヤ（６）は、別途に取り付けた空気圧調整装置により、自動車の走行中でも、空気圧の調整ができるように構成される。 In FIG. 1, (24) is an inner tube tire valve, (26) is an outer tubeless tire valve, and (27) is an air nozzle. The electrodes (10) and (12) of the power generation body (16) are connected to electrical wiring outside the tire (2) through electrical contacts (not shown) disposed on the wheel (4). The outer tubeless tire (8) and the inner tube tire (6) are configured so that the air pressure can be adjusted even while the automobile is running, by a pneumatic pressure adjusting device attached separately.
タイヤ（２）を車体に取り付ける前の無負荷状態では、外側チューブレスタイヤ（８）の内周面と、内側チューブタイヤ（６）の外周面との間隔は数ミリメートルに設定されるが、車体にタイヤ（２）を取り付けると、路面と接する外側チューブレスタイヤ（８）は、車重により、サイドウォール部が図２に示すように屈曲して、内周面が内側チューブタイヤ（６）の外周面に圧着し、発電体（１６）に圧力が加わり、この圧力により発電体（１６）が発電するように構成されている。 In the unloaded state before the tire (2) is attached to the vehicle body, the distance between the inner peripheral surface of the outer tubeless tire (8) and the outer peripheral surface of the inner tube tire (6) is set to several millimeters. When the tire (2) is attached, the outer tubeless tire (8) in contact with the road surface is bent as shown in FIG. 2 by the vehicle weight, and the inner peripheral surface is the outer peripheral surface of the inner tube tire (6). Pressure is applied to the power generation body (16), and the power generation body (16) is configured to generate power by this pressure.
車両が動き出すとタイヤ（２）の振動により、発電体（１６）に連続的に圧力が加わり、とぎれることなく発電体（１６）が発電する。発電体（１６）で発電された電気は、電気自動車やハイブリッド車等のバッテリー充電に使われる。
上記実施形態では、内側チューブタイヤ（６）側に発電体（１６）を一体的に設けたが図８,９に示すように内側チューブタイヤ（６）側と、外側チューブレスタイヤ（８）側の両方に発電体（１６）（１６）を設けるようにしても良い。
When the vehicle starts to move, pressure is continuously applied to the power generation body (16) by the vibration of the tire (2), and the power generation body (16) generates power without interruption. The electricity generated by the power generation body (16) is used for charging a battery of an electric vehicle or a hybrid vehicle.
In the above embodiment, the power generator (16) is integrally provided on the inner tube tire (6) side. However, as shown in FIGS. 8 and 9, the inner tube tire (6) side and the outer tubeless tire (8) side are provided. You may make it provide a power generation body (16) (16) in both.
外側チューブレスタイヤ（８）側の発電体（１６）の一体化固設構造は、図７に示す内側チューブタイヤ（６）側の発電体（１６）の一体化固設構造と同一である。
尚、本発明は、自動車のタイヤ以外に自転車、その他の走行車のタイヤに応用することができる。
The integrated fixing structure of the power generation body (16) on the outer tubeless tire (8) side is the same as the integrated fixing structure of the power generation body (16) on the inner tube tire (6) side shown in FIG.
The present invention can be applied to tires for bicycles and other traveling vehicles in addition to automobile tires.
