It is a figure which shows the base for electronic component attachment.

  That is, as shown in FIGS. 7A and 7B, the electronic component mounting base 101 is for mounting a transponder 107 as an electronic component on the inner liner 105 in the tire 103. The electronic component mounting pedestal 101 includes a first pedestal member 109 made of rubber, and a flat second pedestal member 111 made of a rigid material such as aluminum that is joined to the first pedestal member 109 in a polymerized state. It has.

  The first pedestal member 109 has a first attachment surface 109m that can be directly attached to the surface 105m of the inner liner 105 on one side (lower side in FIG. 7), and the other side (upper side in FIG. 7). ) Has a first joint surface 109b.

  By the way, as described above, the second pedestal member 111 is made of a rigid material such as aluminum, and even when an external force is input due to rolling of the tire 103, the deformation of the electronic component mounting pedestal 101 can be suppressed. However, when the travel distance or travel time of the tire 103 becomes long, the position between the first base member 109 and the second base member 111 is likely to occur due to the external force. Therefore, adhesive peeling occurs between the first pedestal member 109 and the second pedestal member 111, and the electronic component (transponder 107 in FIG. 7) cannot be used in a stable state over a long period of time. There is.

  Accordingly, the present invention provides an electronic component having a novel configuration capable of sufficiently suppressing displacement between the first seat member and the second seat member by an external force even when the tire travel distance or travel time is increased. It is an object of the present invention to provide a mounting base and a tire with a base having a novel structure including the mounting base for the electronic component.

  A first feature of the present invention (feature of the invention described in claim 1) is an electronic component mounting base for mounting an electronic component on a surface of an inner liner in a tire, and directly on the surface of the inner liner on one side. The first pedestal member having a first mounting surface that can be attached to the first pedestal and having a concave portion formed on the other side surface, and the first pedestal member are integrally joined in a state of being superimposed on the first pedestal member, and the bottom surface of the concave portion on one side A plate-like second pedestal member made of a rigid material, having a second attachment surface to which the electronic component can be attached directly or indirectly on the other side, And the wall surface of the concave portion surrounds the outer peripheral surface of the second pedestal member.

  In addition, an electronic component means a transponder, a tire internal pressure monitoring apparatus, etc., for example.

  According to the first feature, the joint surface of the second pedestal member is bonded to the bottom surface of the concave portion formed on the other side surface of the first pedestal member, and the wall surface of the concave portion is the second Since the outer peripheral surface of the pedestal member is surrounded, the first pedestal member and the first pedestal member due to an external force (external force input by rolling of the tire, etc.) and the tire even when the travel distance or travel time of the tire becomes long The positional shift between the second pedestal member and the second pedestal member can be sufficiently suppressed (the positional shift suppressing action between the first pedestal member and the second pedestal member).

  The second feature of the present invention (the feature of the invention described in claim 2) is that in addition to the first feature, the height of the wall surface of the recess (in other words, the depth of the recess) is the second feature. That is, it is 0.5 times or more and twice or less the thickness of the base member.

  Here, the height of the wall surface of the concave portion is set to 0.5 times or more of the thickness of the second pedestal member, when the thickness of the second pedestal member is less than 0.5 times the thickness of the second pedestal member. This is because the effect of suppressing the displacement between the first seat member and the second seat member cannot be effectively exhibited. On the other hand, the reason why the height of the wall surface of the recess is set to not more than twice the thickness of the second pedestal member is that when the thickness exceeds the thickness of the second pedestal member, the electronic component is moved to the second pedestal. It is because it becomes difficult to attach to the said 2nd attachment surface of a member.

  According to the second feature, the height of the wall surface of the recess is not less than 0.5 times and not more than twice the thickness of the second pedestal member. The electronic component can be easily attached to the second attachment surface of the second pedestal member while effectively exerting the effect of suppressing the displacement with respect to the pedestal member.

  Here, the thickness between the first mounting surface of the first pedestal member and the bottom surface of the recess is 2 mm or more because the first mounting surface of the first pedestal member and the bottom surface of the recess are This is because when the thickness between the two is less than 2 mm, the stress generated in the electronic component cannot be sufficiently relaxed when a large external force is input to the tire. On the other hand, the reason why the thickness between the first mounting surface of the first pedestal member and the bottom surface of the recess is 10 mm or less is that the first mounting surface of the first pedestal member and the bottom surface of the recess are This is because if the thickness exceeds 10 mm, the moment acting on the electronic component during running of the tire increases.

  According to the third feature, since the thickness between the first mounting surface of the first base member and the bottom surface of the recess is 2 mm or more and 10 mm or less, a large external force is input to the tire. When this is done, the stress generated in the electronic component can be alleviated more sufficiently, and the moment acting on the electronic component during running of the tire can be reduced.

  According to a fourth feature (feature of the invention described in claim 4) of the present invention, in addition to any one of the first feature to the third feature, the wall surface of the recess is the second pedestal member. It is that it is the shape along the outer peripheral surface.

  The “shape along the outer peripheral surface of the second pedestal member” is preferably a shape in which the entire wall surface of the concave portion is in contact with the outer peripheral surface of the second pedestal member. As long as the shape is along the outer peripheral surface of the member, there may be a gap between the wall surface of the recess and the outer peripheral surface of the second pedestal member.

  In addition to the fifth feature, the sixth feature of the present invention (feature of the invention described in claim 6) is that the other side surface of the first base member and the second base member before vulcanization are performed. A vulcanizing adhesive is applied to at least one of the joint surfaces, and the first surface of the second pedestal member is bonded to the other side surface of the first pedestal member with the vulcanization mold. By forming the recess while vulcanizing the pedestal member, the joint surface of the second pedestal member and the bottom surface of the recess are vulcanized and bonded.

  In addition to the fifth feature, the seventh feature of the present invention (feature of the invention described in claim 7) is that the other side surface of the first base member and the second base member before vulcanization are performed. A vulcanized adhesive is applied to at least one of the joint surfaces and the outer peripheral surface of the second pedestal member, and the joint surface of the second pedestal member and the other side surface of the first pedestal member are bonded together. In this state, the concave portion is formed while vulcanizing the first pedestal member with a vulcanization mold, whereby the joint surface of the second pedestal member, the bottom surface of the concave portion, and the second pedestal The outer peripheral surface of the member and the wall surface of the recess are each vulcanized and bonded.

  According to the seventh feature, in addition to the joint surface of the second pedestal member and the bottom surface of the recess, the outer peripheral surface of the second pedestal member and the wall surface of the recess are also vulcanized and bonded. It is possible to effectively exert a positional deviation suppressing action between the first pedestal member and the second pedestal member.

  In addition to the fifth feature, the eighth feature of the present invention (feature of the invention described in claim 8) is bonded to at least one of the bottom surface of the recess and the joint surface of the second pedestal member. By applying an agent and placing the second pedestal member on the bottom surface of the recess, the bottom surface of the recess and the joining surface of the first pedestal member are bonded.

  The ninth feature of the present invention (the feature of the invention described in claim 9) is, in addition to the fifth feature, at least one of a bottom surface of the recess and the joint surface of the second pedestal member, and By applying an adhesive to at least one of the wall surface of the recess and the outer peripheral surface of the second pedestal member, and placing the second pedestal member on the bottom surface of the recess, the bottom surface of the recess and the The bonding surface of the second pedestal member, the wall surface of the recess, and the outer peripheral surface of the second pedestal member are bonded to each other.

  According to a ninth feature, in addition to the joint surface of the second pedestal member and the bottom surface of the recess, the outer peripheral surface of the second pedestal member and the wall surface of the recess are also bonded. It is possible to effectively exert the effect of suppressing displacement between the first seat member and the second seat member.

  According to a tenth feature of the present invention (a feature of the invention described in claim 10), in addition to any one of the fifth feature to the ninth feature, the raw tire is vulcanized to be predetermined. When the tire having the product shape is molded, the first mounting surface of the first base member is adhered to the surface of the inner liner.

  An embodiment of the present invention will be described with reference to FIGS.

  Here, FIG. 1A is a diagram showing an electronic component mounting base according to the embodiment before being attached to the inner liner, and FIG. 1B is a state after being attached to the inner liner. FIG. 2 is a plan view of an electronic component mounting base according to an embodiment of the electronic component mounting base according to the embodiment of the present invention. 3 is a view showing an electronic component mounting base according to an embodiment of the present invention in which the height of the wall surface of the concave portion is changed, and FIG. 4 is a diagram showing adhesion between the joint surface of the second base member and the bottom surface of the concave portion. FIG. 5 is a view showing another aspect of adhesion between the joint surface of the second pedestal member and the bottom surface of the recess, and FIG. 6 is a pedestal tire according to an embodiment of the present invention. FIG.

  As shown in FIG. 6, a pedestal-equipped tire 1 according to an embodiment of the present invention is attached to a tire 5 that is assembled to a rim 3 and can be filled with air as a working gas, and an inner liner 7 in the tire 5. The electronic component mounting base 9 and a transponder 11 mounted on the electronic component mounting base 9 are provided.

  The specific configuration of the tire 5 in the pedestal-equipped tire 1 is as follows.

  That is, the tire 5 includes a pair of annular bead fillers 13 that can be fitted to the rim 3. Each bead filler 13 includes a bead core 15. Further, a carcass 17 as a skeleton member is integrally provided between the pair of bead fillers 13, and the cross-sectional shape of the carcass 17 has a toroidal shape. Further, a two-layer belt 19 is provided on the outer peripheral surface of the carcass 17.

  A groundable tread 21 is integrally provided on the outer peripheral surface of the carcass 17 so as to cover the belt 19, and a side tread 23 that protects the carcass 17 is integrally formed on one side surface and the other side surface of the carcass 17. Is provided. The inner liner 7 is integrally provided on the inner side surface (including the inner peripheral surface) of the carcass 17 to prevent leakage of air filled in the tire 5.

  The specific structure of the electronic component mounting base 9 in the tire with base 1 is as follows.

  That is, as shown in FIGS. 1A and 1B, an electronic component mounting base 9 is for mounting a transponder 11 as an electronic component on the surface 7m of the inner liner 7, and is a rectangular type (FIG. 2). (See (a)) and circular type (see FIG. 2 (b)). The electronic component mounting pedestal 9 and the electronic component mounting pedestal 9 are made of a first pedestal member 25 made of rubber and joined to the first pedestal member 25 in a polymerized state and made of a rigid material such as aluminum. A flat plate-like second pedestal member 27 is provided. The modulus (elastic modulus) of the second pedestal member 27 is higher than the modulus of the first pedestal member 25, and the second pedestal member 27 is made of a hard resin instead of aluminum. Other rigid materials such as may be used.

  The first pedestal member 25 has a first attachment surface 25m that can be directly attached to the surface 7m of the inner liner 7 on one side (lower side in FIG. 1). A recess 29 is formed on the side surface (upper side surface in FIG. 1) 25t. Further, the second pedestal member 27 has a joining surface 27b that can be joined to the bottom surface 29b of the recess 29 on one side, and the transponder 11 can be directly attached to the other side (upper side in FIG. 1). A second mounting surface 27m. Note that the second mounting surface 27m of the second pedestal member 27 may be configured so that the transponder 11 can be indirectly mounted via another pedestal member or the like superimposed on the second pedestal member 27.

  1A and 2A and 2B, the wall surface 29p of the recess 29 surrounds the outer peripheral surface 27p of the second pedestal member 27. In other words, the recess 29 The wall surface 29p of 29 is shaped to contact the outer peripheral surface 27p of the second pedestal member 27. In addition, as long as the wall surface 29p of the recessed part 29 is a shape which follows the outer peripheral surface 27p of the 2nd pedestal member 27, even if there exists a gap between the wall surface 29p of the recessed part 29 and the outer peripheral surface 27p of the 2nd pedestal member 27. There is no problem.

  The height of the wall surface 29p of the recess 29 (in other words, the depth of the recess 29) is the same as the thickness of the second seat member 27 (in other words, the depth of the second seat member 27), as shown in FIG. Although not limited to 1 times the thickness, as shown in FIGS. 3A and 3B, the thickness of the second pedestal member 27 is 0.5 times or more and 2 times or less. Here, the reason why the height of the wall surface 29p of the recess 29 is set to 0.5 times or more of the thickness of the second pedestal member 27 is less than 0.5 times the thickness of the second pedestal member 27. This is because it is not possible to effectively exhibit the below-described positional deviation suppressing action between the first seat member 25 and the second seat member 27. On the other hand, the reason why the height of the wall surface 29p of the recess 29 is set to be not more than twice the thickness of the second pedestal member 27 is that when the thickness of the second pedestal member 27 exceeds twice, the transponder 11 is moved to the second pedestal member 27. It is because it becomes difficult to attach to 27 2nd attachment surface 27m. The height of the wall surface 29p of the recess 29 is preferably 0.5 times or more and 2 times or less the thickness of the second pedestal member 27, but the height of the wall surface 29p of the recess 29 is the first. Even if it is less than 0.5 times the thickness of the two pedestal members 27, it may be more than twice the thickness of the second pedestal members 27.

  The thickness between the first mounting surface 25m of the first base member 25 and the bottom surface 29b of the recess 29 is 2 mm or more and 10 mm or less. Here, the thickness between the first mounting surface 25m of the first pedestal member 25 and the bottom surface 29b of the recess 29 is set to 2 mm or more because the first mounting surface 25m of the first pedestal member 25 and the bottom surface of the recess 29 are This is because the stress generated in the transponder 11 cannot be relaxed more sufficiently when a large external force is input to the tire 5 (the tire 1 with a pedestal) if the thickness between it and 29b is less than 2 mm. On the other hand, the thickness between the first mounting surface 25m of the first pedestal member 25 and the bottom surface 29b of the concave portion 29 is set to 10 mm or less because the first mounting surface 25m of the first pedestal member 25 and the bottom surface 29b of the concave portion 29 are used. This is because the moment acting on the transponder 11 during traveling of the tire 5 (pedestal-equipped tire 1) increases when the thickness between the two exceeds 10 mm.

  Further, before attaching the electronic component mounting base 9 to the inner liner 7 (in other words, when the electronic component mounting base 9 itself is independent), the first base member 25 is made of semi-vulcanized rubber. Alternatively, it is made of vulcanized rubber. Here, the semi-vulcanized rubber is a rubber in which a crosslinking reaction has not sufficiently occurred, and when the modulus of the rubber at the time of full vulcanization is 100%, it is 30% or more and 80% or less. Modulus rubber. Semi-vulcanized rubber can be produced by shortening the vulcanization time, lowering the vulcanization temperature, or changing the composition of rubber chemicals that contribute to the vulcanization speed. .

  As shown in FIGS. 4A and 4B, the joining surface 27b of the second pedestal member 27 and the bottom surface 29b of the recess 29, and the outer peripheral surface 27p of the second pedestal member 27 and the wall surface 29p of the recess 29 are vulcanized. Applying a vulcanized adhesive to at least one of the other side surface 25t of the first pedestal member 25 and the joint surface 27b of the second pedestal member 27 and the outer peripheral surface 27p of the second pedestal member 27 before applying While the joining surface 27b of the second pedestal member 27 and the other side surface 25t of the first pedestal member 25 are bonded together, the concave portion 29 is formed while vulcanizing the first pedestal member 25 by the vulcanization mold 31. As a result, each is vulcanized and bonded. Alternatively, as shown in FIG. 5, the joint surface 27 b of the second pedestal member 27 and the bottom surface 29 b of the recess 29, and the outer peripheral surface 27 p of the second pedestal member 27 and the wall surface 29 p of the recess 29 are connected to the bottom surface 29 b of the recess 29. Apply an adhesive such as cyanoacrylate to at least one of the joint surfaces 27b of the two pedestal members 27 and at least one of the wall surface 29p of the recess 29 and the outer peripheral surface 27p of the second pedestal member 27, respectively. Then, the second pedestal member 27 is arranged on the bottom surface 29b of the concave portion 29 to be bonded to each other.

  Further, when the electronic component mounting base 9 itself is in an independent state, the first mounting surface 25m of the first base member 25 is provided on the condition that the first base member 25 is made of semi-vulcanized rubber. When the tire 5 having a predetermined product shape is molded by subjecting the raw tire 5 'to vulcanization, it is adhered to the surface 7m of the inner liner 7. Alternatively, when the electronic component mounting base 9 itself is in an independent state, on the condition that the first base member 25 is made of vulcanized rubber, the first mounting surface 25m of the first base member 25 is An adhesive such as cyanoacrylate is applied to at least one of the first mounting surface 25m of the first base member 25 and the surface 7m of the inner liner 7 so that the first base member 25 is applied to the surface 7m of the inner liner 7. By arranging, it adheres to the surface 7m of the inner liner 7.

  The specific configuration of the transponder 11 in the pedestal tire 1 is as follows.

  That is, the transponder 11 is an electronic component used for monitoring the internal pressure and the internal temperature of the tire 5, and is attached to the second attachment surface 27m of the second pedestal member 27 by adhesion with an adhesive such as cyanoacrylate, for example. ing. The transponder 11 may be attached to the second attachment surface 27m of the second base member 27 by a mechanical attachment means such as a slide type.

  Next, the operation and effect of the embodiment of the present invention will be described.

  The joint surface 27b of the second pedestal member 27 is bonded to the bottom surface 29b of the recess 29 formed on the other side surface 25t of the first pedestal member 25, and the wall surface 29p of the recess 29 is the outer periphery of the second pedestal member 27. Since the surface 27p is surrounded, even if the traveling distance or traveling time of the tire 5 (pedestal-equipped tire 1) is increased, the first pedestal member due to external force (external force input by rolling of the tire 5 or the like) 25 and the second pedestal member 27 can sufficiently suppress the above-described positional deviation (positional displacement restraining action between the first pedestal member 25 and the second pedestal member 27). In particular, in addition to the joint surface 27b of the second pedestal member 27 and the bottom surface 29b of the recess 29, the outer peripheral surface 27p of the second pedestal member 27 and the wall surface 29p of the recess 29 are also bonded (including vulcanization bonding). Therefore, it is possible to effectively exhibit the positional deviation suppressing action between the first pedestal member 25 and the second pedestal member 27.

  Moreover, since the height of the wall surface 29p of the recessed part 29 is 0.5 times or more and 2 times or less of the thickness of the 2nd base member 27, between the 1st base member 25 and the 2nd base member 27, it is. The transponder 11 can be easily attached to the second attachment surface 27m of the second pedestal member 27 while effectively exerting the effect of suppressing the displacement between them.

  Furthermore, since the thickness between the first mounting surface 25m of the first base member 25 and the bottom surface 29b of the recess 29 is 2 mm or more and 10 mm or less, when a large external force is input to the tire 5 The stress generated in the transponder 11 can be relaxed more sufficiently, and the moment acting on the transponder 11 while the tire 5 is traveling can be reduced.

  Therefore, according to the embodiment of the present invention, even if the travel distance or travel time of the tire 5 becomes long, it is possible to sufficiently suppress the occurrence of positional displacement between the first base member 25 and the second base member 27 due to external force. Therefore, adhesion peeling between the first pedestal member 25 and the second pedestal member 27 is difficult to occur, and the transponder 11 can be used in a stable state for a long time.

  Further, when a large external force is input to the tire 5, stress generated in the transponder 11 can be more sufficiently relaxed, and the moment acting on the transponder 11 during traveling of the tire 5 can be reduced. The above-described effects can be further improved by suppressing the damage of the transponder 11.

  The present invention can be implemented in various modes other than the above-described embodiments. Further, the scope of rights encompassed by the present invention is not limited to these embodiments.
