タイヤ情報取得装置がモニタリングする対象がタイヤ内圧などの場合には、タイヤ情報取得装置がゴム台座内で回転しても問題はないが、モニタリングする対象が周方向加速度などの方向性のあるタイヤ情報である場合には、タイヤ情報の検出精度が低下してしまう、といった問題点があった。
また、モニタリングする対象が方向性を持たない場合でも、タイヤ情報取得装置がアンテナを備えている場合には、タイヤ情報取得装置がゴム台座内で回転してしまうと、モニタリングしたデータの送信に支障をきたすおそれがあった。 However, in the configuration in which the cylindrical electronic monitoring device is mounted on the rubber pedestal having the cylindrical storage portion as in Patent Document 1, the tire information acquisition device may rotate in the rubber pedestal during use. there were.
When the tire information acquisition device monitors the tire internal pressure or the like, there is no problem if the tire information acquisition device rotates within the rubber pedestal, but the monitoring target is tire information with directionality such as circumferential acceleration. In such a case, there is a problem that the detection accuracy of the tire information is lowered.
Even if the object to be monitored has no directionality, if the tire information acquisition device is equipped with an antenna, if the tire information acquisition device rotates within the rubber pedestal, transmission of the monitored data will be hindered. There was a risk of causing.

本発明は、従来の問題点に鑑みてなされたもので、使用中にタイヤ情報取得装置がゴム台座内で回転してしまうことを抑止することを目的とする。   The present invention has been made in view of the conventional problems, and an object of the present invention is to prevent the tire information acquisition device from rotating in a rubber pedestal during use.

本発明は、タイヤの情報を取得するセンサを備えたセンサモジュールと、前記センサモジュールを収納する筺体とを備えたタイヤ情報取得装置と、前記タイヤ情報取得装置を装着して前記タイヤ内面に取付けられるゴム台座とを備えたゴム台座付きタイヤ情報取得装置であって、前記筺体が、一方の面がタイヤ内面に取付けられ、他方の面に前記センサモジュールが取付けられる板状の底部と、前記底部に接続されて、前記センサモジュールの側面を覆う、円筒状の側壁部とを備え、前記底部の、前記側壁部を構成する円筒の中心から測ったタイヤ径方向と直交する方向のうちの一方の方向の長さ寸法ｌbが、前記円筒の半径をｒとしたとき、ｌb≧ｒで、前記円筒の中心から測ったタイヤ径方向と直交する方向のうちの他方の方向の長さ寸法ｌaが、ｌa≧ｌbで、かつ、前記円筒の中心から測った当該底部の周縁部までの距離の最大値Ｌがｌa＝ｌbのときにはＬ＞ｌaで、ｌa＞ｌbのときには、Ｌ≧ｌaであることを特徴とする。
これにより、使用中にタイヤ情報取得装置がゴム台座内で回転してしまうことを抑制することができるので、長期間に亘り、タイヤの情報を安定して取得することができる。
また、前記底部のタイヤ内面側の面を、前記タイヤの内面に沿った凸面として、タイヤの踏込時における衝撃を緩和できるようにしたので、タイヤ情報取得装置の耐久性を向上させることができる。 The present invention provides a tire information acquisition device including a sensor module including a sensor for acquiring tire information, a housing for housing the sensor module, and the tire information acquisition device attached to the tire inner surface. A tire information acquisition apparatus with a rubber pedestal comprising a rubber pedestal, wherein the housing has a plate-like bottom portion on which one surface is attached to the inner surface of the tire and the sensor module is attached to the other surface; A cylindrical side wall part connected to cover the side surface of the sensor module, and one direction of the bottom part perpendicular to the tire radial direction measured from the center of the cylinder constituting the side wall part the length l b is, when the radius of the cylindrical and the r, with l b ≧ r, the other direction of the length dimension of the direction perpendicular to the tire radial direction measured from the center of the cylindrical l a is at l a ≧ l b, and, when the maximum value L of the distance to the periphery of the bottom portion as measured from the center of the cylinder of l a = l b in L> l a, l a> l When b , L ≧ l a .
Thereby, since it can suppress that a tire information acquisition apparatus rotates within a rubber pedestal during use, the information on a tire can be acquired stably over a long period of time.
In addition, since the surface on the tire inner surface side of the bottom portion is a convex surface along the inner surface of the tire so as to reduce the impact when the tire is stepped on, the durability of the tire information acquisition device can be improved.

The tire information acquisition apparatus 10G with a rubber pedestal covers the apparatus main body 11 including a sensor module 11A including a sensor (not shown) that acquires tire information such as tire circumferential acceleration and the like, and a power supply unit 11B, and the apparatus main body 11 from the outside. A tire information acquisition device 10 including a housing 12, and a rubber base 20 that includes a bottom plate 21 and a pair of holding portions 22 </ b> A and 22 </ b> B and is attached to the inner surface of the tire 30 by mounting the tire information acquisition device 10.

図１（ａ），（ｂ）に示すように、本例では、電源部１１Ｂとして、円板状の電池（いわゆる、ボタン電池）を用いるとともに、センサモジュール１１Ａの形状を、ボタン電池の半径と同じ半径ｒを有する円板状に形成し、センサモジュール１１Ａをタイヤ３０の内面側に配置し、このセンサモジュール１１Ａの上側であるタイヤ径方向に電源部１１Ｂを配置した。
すなわち、本例のタイヤ情報取得装置１０は、センサモジュール１１Ａと電源部１１Ｂとを縦積みにすることで、装置本体１１を円筒状とし、この円筒状の装置本体１１を筺体１２で覆う構成となっている。
以下、センサモジュール１１Ａと電源部１１Ｂの積層方向であるタイヤ径方向を上下方向、タイヤ周方向を長さ方向、タイヤ幅方向を幅方向とする。また、装置本体１１の円筒の半径をｒ0とする。 As shown in FIGS. 1A and 1B, in this example, a disk-shaped battery (so-called button battery) is used as the power supply unit 11B, and the shape of the sensor module 11A is set to the radius of the button battery. The sensor module 11A is disposed on the inner surface side of the tire 30 and the power supply unit 11B is disposed in the tire radial direction on the upper side of the sensor module 11A.
That is, the tire information acquisition device 10 of this example has a configuration in which the device body 11 is formed in a cylindrical shape by vertically stacking the sensor module 11A and the power supply unit 11B, and the cylindrical device body 11 is covered with the casing 12. It has become.
Hereinafter, the tire radial direction that is the stacking direction of the sensor module 11A and the power supply unit 11B is the vertical direction, the tire circumferential direction is the length direction, and the tire width direction is the width direction. The radius of the cylinder of the apparatus main body 11 is r 0 .

筐体１２は、平板状の底部１２ａと、底部１２ａから上側に立設された厚さ寸法がｄ、半径がｒの円筒状の側壁部１２ｂと、側壁部１２ｂの上部に設けられて側壁部１２ｂの上面を覆う円板状の蓋部１２ｃとを備える。側壁部１２ｂ円筒の半径はｒ＝ｒ0＋ｄである（ｒ0；装置本体１１の円筒の半径）。
底部１２ａは、装置本体１１の中心でもある底部１２ａの中心Ｏから長さ方向の端部Ａまでの長さ寸法がｌa、幅方向の端部Ｂまでの長さ寸法がｌb（ｌa＞ｌb）である長方形の４つの角部を面取りした形状で、側壁部１２ｂは、その中心が、円筒状の装置本体１１の中心である矩形の中心と一致するように、底部１２ａに立設される。なお、ここでは、Ｒ面取りしたがＣ面取りでも良い（Ｒ面取りの場合、Ｒ＜ｌaである）。
本例では、図１（ｃ）に示すように、ｌa＞ｌbとするとともに、ｌb＝ｒとした。
また、底部１２ａの中心Ｏから底部１２ａの端部までの距離は、底部１２ａの中心Ｏと面取りする前の矩形の頂点へ向かう直線と面取り部との交点Ｃとの距離が最大で、この距離の最大値Ｌとすると、Ｌ＞ｌaである。図１（ｂ）に示すように、筐体１２の平板状の底部１２ａが、ゴム台座２０の収納空間２０Ｓ内に収納されるので、距離の最大値Ｌが、タイヤ情報取得装置１０とゴム台座２０との嵌め合い長さの最大値となる。
なお、図１（ａ）に示すように、底部１２ａの装置本体１１の直下の部分に円筒状の浅い凹部１２ｋを設けて、この凹部１２ｋの底部に装置本体１１の底部を設置すれば、筐体１２の高さを低くできるので、タイヤ情報取得装置１０を小型・軽量化できる。
また、本例では、図１（ａ）に示すように、底部１２ａの下側の面（タイヤ内面側の面）を、タイヤの内面に沿った凸な面としたので、タイヤの踏込時における衝撃を緩和することができる。 The housing 12 is provided with a flat bottom 12a, a cylindrical side wall 12b having a thickness d standing on the upper side from the bottom 12a, a radius r, and an upper side of the side wall 12b. And a disc-shaped lid 12c covering the upper surface of 12b. The radius of the cylinder of the side wall portion 12b is r = r 0 + d (r 0 ; radius of the cylinder of the apparatus main body 11).
Bottom portion 12a, the apparatus body from the center O of the bottom portion 12a, which is also the center of the 11 to the end A of the longitudinal length dimension l a, the width direction of the edge length dimension l b (l a to B > the four corners of the rectangle is l b) with the chamfered shape, side wall portion 12b has its center, so as to coincide with the center of the rectangle is the center of the cylindrical device body 11, the bottom portion 12a standing Established. Here, although the R chamfering may be C-chamfered (for R chamfering is R <l a).
In this example, as shown in FIG. 1C, l a > l b and l b = r.
The distance from the center O of the bottom portion 12a to the end of the bottom portion 12a is the maximum distance between the center O of the bottom portion 12a and the intersection C of the chamfered portion with the straight line toward the vertex of the rectangle before chamfering. If the maximum value L of an L> l a. As shown in FIG. 1B, since the flat bottom portion 12a of the housing 12 is stored in the storage space 20S of the rubber pedestal 20, the maximum distance L is determined by the tire information acquisition device 10 and the rubber pedestal. 20 and the maximum fitting length.
As shown in FIG. 1A, if a cylindrical shallow concave portion 12k is provided in a portion of the bottom portion 12a immediately below the device main body 11, and the bottom portion of the device main body 11 is installed at the bottom portion of the concave portion 12k, a housing is provided. Since the height of the body 12 can be reduced, the tire information acquisition device 10 can be reduced in size and weight.
Further, in this example, as shown in FIG. 1 (a), the lower surface (surface on the tire inner surface side) of the bottom portion 12a is a convex surface along the inner surface of the tire. Impact can be mitigated.

筺体１２は、例えば、図１に示した筐体１２を、タイヤ周方向に半割りした一対の樹脂成形物から構成される。一対の樹脂成形物は、筐体１２をタイヤ幅方向に半割りしたものであってもよい。
なお、装置本体１１が設置されたモールド内にウレタン樹脂やエポキシ樹脂などの樹脂材料を注入して固化させることで筺体１２を形成してもよい。
あるいは、装置本体１１の表面に、ウレタン樹脂やエポキシ樹脂などをコーティングして筐体１２を形成してもよい。コーティングの方法としては、デッピングや塗布など、周知の方法を用いることができる。 The housing 12 is comprised from a pair of resin molding which divided the housing | casing 12 shown in FIG. 1 into the tire circumferential direction, for example. The pair of resin moldings may be obtained by dividing the casing 12 in half in the tire width direction.
The casing 12 may be formed by injecting a resin material such as urethane resin or epoxy resin into a mold in which the apparatus main body 11 is installed and solidifying the resin material.
Alternatively, the housing 12 may be formed by coating the surface of the apparatus main body 11 with urethane resin, epoxy resin, or the like. As a coating method, a known method such as dipping or coating can be used.

ゴム台座２０は、図１（ａ），（ｂ）に示すように、底板２１と一対の保持部２２Ａ，２２Ｂとを備えたゴム部材から成り、タイヤ情報取得装置１０を装着するための円形の開口部２０Ｋと、筺体１２の底部１２ａを収納するための収納空間２０Ｓとを有する。
底板２１の形状は筺体１２の底部１２ａと相似形で、底板２１のタイヤ周方向両端の周縁部側に、底板２１から立ち上がって、筺体１２の底部１２ａのタイヤ内面側とは反対側を覆う一対の保持部２２Ａ，２２Ｂの周縁部が取付けられる。底板２１と保持部２２Ａ，２２Ｂとにより、収納空間２０Ｓが形成される。
すなわち、底板２１と保持部２２Ａ，２２Ｂとの作る空間が、タイヤ情報取得装置１０とゴム台座２０との嵌め合い部となる収納空間２０Ｓとなる。 As shown in FIGS. 1A and 1B, the rubber pedestal 20 is made of a rubber member having a bottom plate 21 and a pair of holding portions 22A and 22B, and has a circular shape for mounting the tire information acquisition device 10. An opening 20K and a storage space 20S for storing the bottom 12a of the housing 12 are provided.
The shape of the bottom plate 21 is similar to the bottom portion 12a of the casing 12, and is a pair that rises from the bottom plate 21 on the peripheral edge sides at both ends in the tire circumferential direction of the bottom plate 21 and covers the side opposite to the tire inner surface side of the bottom portion 12a of the casing 12. The peripheral portions of the holding portions 22A and 22B are attached. A storage space 20S is formed by the bottom plate 21 and the holding portions 22A and 22B.
That is, the space formed by the bottom plate 21 and the holding portions 22 </ b> A and 22 </ b> B becomes a storage space 20 </ b> S that is a fitting portion between the tire information acquisition device 10 and the rubber pedestal 20.

このように、本実施の形態１では、筺体１２を、側壁部１２ｂを構成する円筒の中心から測った板状の底部１２ａのタイヤ周方向の長さｌaと、前記円筒の中心から測ったタイヤ幅の長さ寸法ｌbと、前記円筒の中心と底部１２ａの周縁部までの距離の最大値Ｌとが、以下の式（１）を満たすように構成した。
Ｌ＞ｌa＞ｌb、ｌb＝ｒ＋ｄ ……（１）
但し、ｒ；装置本体の半径、ｄ；側壁部肉厚
これにより、タイヤ情報取得装置１０に衝撃力が作用したときに発生するゴム台座２０からの反力が、タイヤ情報取得装置１０を中心Ｏ周りに回転させるモーメントとなる成分の他に、タイヤ情報取得装置１０を締め付ける成分を有するので、タイヤ情報取得装置１０がゴム台座２０内で回転してしまうことを抑制することができる。
したがって、このようなゴム台座付きタイヤ情報取得装置１０Ｇをタイヤ内面に取付けて、タイヤ３０に作用する加速度などのタイヤ情報を取得すれば、長期間に亘り、タイヤの情報を安定して取得することができる。 Thus, in the first embodiment, the housing 12, and the tire circumferential direction length l a of the plate-shaped bottom 12a as measured from the center of the cylinder constituting the side wall portion 12b, as measured from the center of the cylindrical and length l b of the tire width, the maximum value L of the distance to the periphery and the center of the bottom portion 12a of the cylinder, and configured so as to satisfy the following equation (1).
L> l a > l b , l b = r + d (1)
However, r: radius of the apparatus main body, d: thickness of the side wall portion. Thereby, the reaction force generated from the rubber pedestal 20 when an impact force acts on the tire information acquisition apparatus 10 is centered on the tire information acquisition apparatus 10. Since it has a component which tightens tire information acquisition device 10 in addition to a component used as a moment to rotate around, it can control that tire information acquisition device 10 rotates within rubber base 20.
Therefore, if such tire information acquisition device 10G with a rubber pedestal is attached to the tire inner surface and tire information such as acceleration acting on the tire 30 is acquired, tire information can be stably acquired over a long period of time. Can do.

実施の形態２．
前記実施の形態１では、底部１２ａの中心Ｏから測ったタイヤ周方向の長さ寸法ｌaと、タイヤ幅の長さ寸法ｌbと、周縁部までの距離の最大値Ｌとが、Ｌ＞ｌa＞ｌbである場合について説明したが、図２（ａ），（ｂ）に示すように、一辺の長さが２×ｌaである正方形の４つの角部を面取りした形状としてもよい。
この場合には、ｌaとｌbと最大値Ｌとの関係が、Ｌ＞ｌa＝ｌbとなるが、この場合も、タイヤ情報取得装置１０に衝撃力が作用したときに発生するゴム台座２０からの反力が、タイヤ情報取得装置１０を締め付ける成分を有するので、タイヤ情報取得装置１０がゴム台座２０内で回転してしまうことを抑制することができる。
なお、図２（ａ）に示すように、底部１２ａ下側の面を平板状としてもよい。特に、装置本体１１が小さい場合にはタイヤの踏込時における衝撃力の影響が少ないので、底部１２ａ下側の面を平板状としたほうが、筺体１２の作製が容易となるので好ましい。 Embodiment 2. FIG.
In the first embodiment, the tire circumferential direction length l a as measured from the center O of the bottom portion 12a, and the length l b of the tire width, and a maximum value L of the distance to the periphery, L> Although the case where l a > l b has been described, as shown in FIGS. 2A and 2B, it is possible to form a shape in which four corners of a square having a side length of 2 × l a are chamfered. Good.
In this case, the relationship between l a , l b and the maximum value L is L> l a = l b . In this case as well, rubber generated when an impact force is applied to the tire information acquisition device 10. Since the reaction force from the pedestal 20 has a component that tightens the tire information acquisition device 10, the tire information acquisition device 10 can be prevented from rotating in the rubber pedestal 20.
In addition, as shown to Fig.2 (a), it is good also considering the surface below the bottom part 12a as flat form. In particular, when the apparatus main body 11 is small, the influence of the impact force when the tire is stepped on is small. Therefore, it is preferable to make the bottom surface of the bottom portion 12a flat so that the housing 12 can be easily manufactured.

実施の形態３．
前記実施の形態１，２では、タイヤ周方向の長さ寸法ｌaが、周縁部までの距離の最大値Ｌとの関係がＬ＞ｌaである場合について説明したが、Ｌ＝ｌaであってもよい。但し、この場合には、ｌa＞ｌbとする必要がある。
底部１２ａの形状がＬ＝ｌa＞ｌbを満たす例としては、図３に示すような、矩形の互いに対向する２つの辺にそれぞれ半円を付加した、トラック状のものや、図４に示すような、円のタイヤ幅方向の両端に円弧状の切欠き部１２Ｐを設けたものなどが挙げられる。
あるいは、図５に示すような、円の周方向の両端に円弧状の突出部１２Ｑを設けたものであってもよい。
このように、ｌaとｌbと最大値Ｌとの関係が、Ｌ＝ｌa＞ｌbであっても、タイヤ情報取得装置１０に衝撃力が作用したときに発生するゴム台座２０からの反力が、タイヤ情報取得装置１０を締め付ける成分を有するので、タイヤ情報取得装置１０がゴム台座２０内で回転してしまうことを抑制することができる。 Embodiment 3 FIG.
In the first and second embodiments, the length l a of the tire circumferential direction, but the relationship between the maximum value L of the distance to the periphery has been described is L> l a, at L = l a There may be. However, in this case, it is necessary to satisfy l a > l b .
As an example in which the shape of the bottom portion 12a satisfies L = l a > l b , as shown in FIG. 3, a track-like shape in which semicircles are added to two opposite sides of a rectangle, or FIG. As shown, there may be mentioned a circular notch 12P provided at both ends in the tire width direction of a circle.
Alternatively, as shown in FIG. 5, arcuate protrusions 12Q may be provided at both ends in the circumferential direction of the circle.
Thus, the relationship between l a and l b and the maximum value L, even L = l a> l b, from rubber seat 20 that occurs when an impact force is applied to a tire information obtaining device 10 Since the reaction force has a component that tightens the tire information acquisition device 10, the tire information acquisition device 10 can be prevented from rotating in the rubber pedestal 20.

以上、本発明を実施の形態及び実施例を用いて説明したが、本発明の技術的範囲は前記実施の形態に記載の範囲には限定されない。前記実施の形態に、多様な変更または改良を加えることが可能であることが当業者にも明らかである。そのような変更または改良を加えた形態も本発明の技術的範囲に含まれ得ることが、特許請求の範囲から明らかである。   As mentioned above, although this invention was demonstrated using embodiment and an Example, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the embodiment. It is apparent from the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.

例えば、前記実施の形態では、タイヤ径方向と直交する方向のうちの一方の方向をタイヤ周方向とし、他方の方向をタイヤ幅方向とし、筺体１２の底部１２ａのタイヤ周方向の長さをタイヤ幅方向の長さよりも長くしたが、タイヤ径方向と直交する２方向、及び、長さ寸法の長い方向についてはこれに限るものではなく、センサの種類等に応じて適宜決定すればよい。
また、前記実施の形態では、ｌb＝ｒとしたが、図５（ｂ）に示すように、ｌb＞ｒとしてもよい。この場合、筺体１２の体積及び重量は増加するが、ゴム台座２０への嵌め合い部分と体積が増加するので、タイヤ情報取得装置１０をゴム台座２０に安定して装着できるという利点がある。 For example, in the above-described embodiment, one of the directions orthogonal to the tire radial direction is the tire circumferential direction, the other direction is the tire width direction, and the length of the bottom 12a of the housing 12 in the tire circumferential direction is the tire. Although the length is longer than the length in the width direction, the two directions orthogonal to the tire radial direction and the direction in which the length dimension is long are not limited to this, and may be appropriately determined according to the type of sensor.
In the above embodiment, l b = r. However, as shown in FIG. 5B, l b > r may be used. In this case, although the volume and weight of the housing 12 are increased, the volume of the fitting part to the rubber pedestal 20 and the volume are increased, so that there is an advantage that the tire information acquisition device 10 can be stably attached to the rubber pedestal 20.
