Description

本発明は、無線信号を送信または受信するアンテナと、アンテナと接続され、所定の情報を記録するメモリを含む電子部品とを備え、タイヤの内部に設けられる無線通信装置及び無線通信装置を備えるタイヤに関する。   The present invention includes an antenna that transmits or receives a radio signal, and an electronic component that is connected to the antenna and includes a memory that records predetermined information, and a radio communication device provided inside the tire and a tire including the radio communication device About.

従来、タイヤの製造管理情報を記録するメモリなどの電子部品と、製造管理情報を含む無線信号を送信又は受信するアンテナとにより構成される無線通信装置をタイヤの内部に設ける方法が知られている。   2. Description of the Related Art Conventionally, there is known a method of providing a wireless communication device including an electronic component such as a memory that records tire manufacturing management information and an antenna that transmits or receives a wireless signal including manufacturing management information inside the tire. .

一般的に、このような無線通信装置の電子部品を構成する基板は、低弾性の樹脂で形成されている。このため、基板は、タイヤの転動に伴うタイヤの屈曲、又は伸縮等に追従できず、破断して、電子部品が故障してしまうことが懸念されている。そこで、金属で形成されるリム・ホイールに組み付けられるため、変形の少ないビードコアの近傍に無線通信装置を設ける方法が知られている（例えば、特許文献１）。   In general, a substrate constituting an electronic component of such a wireless communication device is formed of a low elasticity resin. For this reason, the board cannot follow the bending or expansion / contraction of the tire accompanying the rolling of the tire, and there is a concern that the board breaks and the electronic component breaks down. Therefore, a method of providing a wireless communication device in the vicinity of a bead core with little deformation because it is assembled to a rim wheel formed of metal is known (for example, Patent Document 1).

特開平８−６７１１７号公報（第３−４頁、第１図）JP-A-8-67117 (page 3-4, FIG. 1)

しかしながら、このような無線通信装置は、金属性のリム・ホイールの影響を受けて、
無線通信装置のアンテナと、外部の通信装置との間で交わされる無線通信が電波障害を受けやすい点で更なる改良が求められていた。 However, such wireless communication devices are affected by metallic rim wheels,
There has been a demand for further improvement in that the wireless communication exchanged between the antenna of the wireless communication device and the external communication device is susceptible to radio interference.

そこで、本発明は、タイヤの内部に設けられ、電子部品及びアンテナを備える無線通信装置において、電子部品の故障の発生を抑制しつつ、電波障害を受けにくい無線通信装置及び無線通信装置を備えるタイヤの提供を目的とする。   Therefore, the present invention provides a wireless communication device that is provided inside a tire and includes an electronic component and an antenna. The tire includes a wireless communication device and a wireless communication device that are less susceptible to radio wave interference while suppressing the occurrence of a failure of the electronic component. The purpose is to provide.

上述した課題を解決するため、本発明は、次のような特徴を有している。まず、本発明の第１の特徴は、無線信号を送信または受信するアンテナ（アンテナ１０）と、前記アンテナと接続され、所定の情報を記録するメモリを含む電子部品（電子部品２０）とを備え、タイヤ（タイヤ１）の内部に設けられる無線通信装置（無線通信装置１００）であって、前記タイヤのタイヤ径方向（タイヤ径方向Ｄ）及びトレッド幅方向（トレッド幅方向Ｗ）に沿った断面において、前記電子部品は、前記タイヤが組み付けられるリム・ホイール（リム・ホイール８）のタイヤ径方向外側端（リム最外位置Ｐ１）を通り、トレッド幅方向に沿って延びるリムライン（リムラインＬ１）よりもタイヤ径方向内側に設けられ、前記アンテナは、前記リムラインよりもタイヤ径方向外側に設けられることを要旨とする。   In order to solve the above-described problems, the present invention has the following features.

A stretchable part (for example, the stretchable part 12) that expands and contracts is provided, and the stretchable part is formed into a wave shape, a zigzag shape, or a spiral shape along the tire circumferential direction.

本発明の第３の特徴は、本発明の第１又は２の特徴に係り、前記アンテナは、前記タイヤの内部と同一のゴム部材によってコーティングされることを要旨とする。   A third feature of the present invention relates to the first or second feature of the present invention, and is summarized in that the antenna is coated with the same rubber member as the inside of the tire.

本発明の第４の特徴は、無線信号を送信または受信するアンテナと、前記アンテナと接続され、所定の情報を記録するメモリを含む電子部品とを有する無線通信装置を備えるタイヤであって、前記タイヤのタイヤ径方向及びトレッド幅方向に沿った断面において、前記電子部品は、前記タイヤが組み付けられるリム・ホイールのタイヤ径方向外側端を通り、トレッド幅方向に沿って延びるリムラインよりもタイヤ径方向内側に設けられ、前記アンテナは、前記リムラインよりもタイヤ径方向外側に設けられる無線通信装置を備えるタイヤ。   According to a fourth aspect of the present invention, there is provided a tire including a wireless communication device having an antenna that transmits or receives a wireless signal, and an electronic component that is connected to the antenna and includes a memory that records predetermined information.

本実施形態によれば、アンテナ１０は、金属線によって形成され、アンテナ１０には、タイヤ径方向Ｄ及びタイヤ周方向Ｒに沿って伸縮する伸縮部１２が設けられる。このため、アンテナ１０は、タイヤの転動に伴うタイヤの屈曲、又は伸縮に追従しやすくなる。   According to this embodiment, the antenna 10 is formed of a metal wire, and the antenna 10 is provided with the expansion / contraction part 12 that expands and contracts along the tire radial direction D and the tire circumferential direction R. For this reason, the antenna 10 becomes easy to follow the bending or expansion / contraction of the tire accompanying the rolling of the tire.

また、伸縮部１２は、タイヤ周方向Ｒに沿って波状に形成されるため、タイヤ径方向Ｄ及びタイヤ周方向Ｒに沿って伸縮する。このため、アンテナ１０は、断線しにくくなる。また、変形例によれば、伸縮部１２Ａ及び伸縮部１２Ｂは、タイヤ周方向Ｒに沿ってジグザグ状又は螺旋状に形成されるため、タイヤ径方向Ｄ及びタイヤ周方向Ｒに沿って確実に伸縮する。つまり、アンテナ１０は、変形しやすい箇所に設けられても、断線による故障の発生を抑制できる。   Moreover, since the expansion-contraction part 12 is formed in a wave shape along the tire circumferential direction R, it expands and contracts along the tire radial direction D and the tire circumferential direction R. For this reason, it becomes difficult for the antenna 10 to be disconnected. In addition, according to the modified example, the expansion / contraction part 12A and the expansion / contraction part 12B are formed in a zigzag shape or a spiral shape along the tire circumferential direction R. To do. That is, even if the antenna 10 is provided at a place where it is easily deformed, the occurrence of a failure due to disconnection can be suppressed.

本実施形態によれば、アンテナ１０は、タイヤ１の内部と同一のゴム部材によってコーティングされる。このため、アンテナ１０のコーティング層は、タイヤ１と、同様に変形する。つまり、アンテナ１０は、タイヤの転動に伴うタイヤの屈曲、又は伸縮に追従しやすくなるため、アンテナ１０にかかる負荷を低減でき、故障の発生を更に抑制できる。   According to this embodiment, the antenna 10 is coated with the same rubber member as the inside of the tire 1. For this reason, the coating layer of the antenna 10 is deformed similarly to the tire 1. That is, since the antenna 10 can easily follow the bending or expansion / contraction of the tire accompanying the rolling of the tire, the load applied to the antenna 10 can be reduced and the occurrence of failure can be further suppressed.

本実施形態によれば、電子部品２０とアンテナ１０とを備える無線通信装置１００が内部に設けられた場合でも、電子部品２０及びアンテナ１０の故障の発生を抑制しつつ、電波障害を受けにくい無線通信装置１００を備えるタイヤ１を提供できる。   According to the present embodiment, even when the wireless communication device 100 including the electronic component 20 and the antenna 10 is provided inside, the wireless communication device is less susceptible to radio wave interference while suppressing the occurrence of the failure of the electronic component 20 and the antenna 10. A tire 1 including the communication device 100 can be provided.

However, the strength of the connection portion may be increased in consideration of the rigidity difference between the antenna 10 and the electronic component 20. For example, the antenna 10 may be firmly connected to the electronic component 20 by thickening a metal wire at a connection portion with the electronic component 20.

上述した実施形態において、伸縮部１２は、リムラインＬ１よりも、タイヤ径方向外側に設けられるとしたが、リムラインＬ１よりも、タイヤ径方向外側の全てが伸縮部１２により構成されていてもよい。   In the embodiment described above, the expansion / contraction part 12 is provided on the outer side in the tire radial direction than the rim line L1, but all the outer side in the tire radial direction than the rim line L1 may be configured by the expansion / contraction part 12.
