JP 2006-151372 A

  Incidentally, in recent years, an acceleration sensor is used as an electronic device attached to a tire, and high-frequency vibration caused by friction between the tire and a road surface during travel is measured, and the measured value is analyzed to estimate a road surface state of the road surface. It has been broken. When measuring such high-frequency vibrations, it is necessary to support the sensor so that the sensor interlocks with the tire inner surface by relatively firmly tightening the electronic device having the acceleration sensor. However, when an electronic device is fixed with a rubber patch, a sufficient tightening force cannot be obtained depending on the material of the rubber. In this case, there is a difference between the movement of the tire inner surface and the movement of the sensor, and there is a possibility that measurement cannot be obtained with a desired accuracy.

  It is also conceivable to increase the adhesive force by increasing the thickness of the rubber. However, when the thickness of the rubber is increased, the vibration transmitted to the electronic device is attenuated, and there is a possibility that the measured value cannot be obtained with high accuracy. Further, when the thickness of the rubber patch is increased, the weight of the rubber patch increases, and the balance of the tire may be deteriorated.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an electronic device mounting apparatus that can increase the adhesive force of the electronic device to the tire surface while maintaining the balance of the tire.

  An electronic device mounting device (electronic device mounting device 10) according to the present invention is an electronic device mounting device for mounting an electronic device (electronic device 7) on an inner liner (inner liner 4) side of a tire (tire 1).

A portion (housing portion 12a), a wedge portion (wedge portion 13) fitted to the electronic device housed in the housing portion, and the housing portion and the wedge portion in a state where the electronic device and the wedge portion are fitted A restriction part (plate part 14) that engages with at least one of the electronic devices and restricts the movement of the wedge part from the inside of the storage part to the outside of the storage part; And a rear end portion (rear end portion 14b) serving as a rear end when inserted into the storage portion. The thickness varies along the direction, and is configured such that the thickness at the rear end is greater than the tip, and the wedge is guided to the storage along the electronic device, The gist is that the wedge portion and the electronic device are fitted, and the restricting portion is engaged with at least one of the storage portion and the electronic device.

  According to the electronic device mounting apparatus according to the present invention, since the electronic device can be mounted on the tire via the electronic device mounting apparatus by fitting the wedge portion and the electronic device, the adhesive force to the tire surface is increased. Can be measured with the desired accuracy. In addition, since the desired adhesive strength can be obtained without increasing the rubber thickness like a rubber patch, deterioration of the balance of the tire can be suppressed. Further, since the movement of the wedge portion stored in the storage portion from the inside of the storage portion to the outside of the storage portion is restricted by the restriction portion, it is possible to prevent the electronic device once stored from moving outside the storage portion. it can.

(2) Configuration of Electronic Device Mounting Device FIG. 2 is a cross-sectional view of the electronic device mounting device and the electronic device in a cross section along the tire circumferential direction shown in FIG. FIG. 3 is a cross-sectional view taken along the line AA of FIG. The electronic device mounting apparatus 10 includes a pedestal portion 11 that is directly or indirectly attached to the surface of the inner liner 4, a storage portion 12 that is joined to the pedestal portion 11 and has a storage space for storing the electronic device 7, and a storage portion 12 includes a wedge portion 13 that fits into the electronic device 7 housed in the plate 12 and a plate portion 14 that serves as a restriction portion that restricts the movement of the wedge portion 13.

  The pedestal 11 has a fixed surface 11a that is directly or indirectly attached to the surface of the inner liner 4 and is made of an elastomer. The storage portion 12 is joined to the facing surface 11b side of the pedestal portion 11 that faces the fixed surface 11a. The pedestal portion 11 is formed so that the area of the facing surface 11b is smaller than the fixed surface 11a, and has a tapered shape in the Z direction shown in FIGS. The bottom surface of the pedestal portion 11 serves as a fixed surface 11a that is fixed to the tire surface (in this embodiment, an inner liner).

  FIG. 4 is a perspective view of the storage unit 12. The storage portion 12 has a cylindrical shape having a pair of openings 12c, and the axial direction thereof is along the X direction shown in FIGS. The hollow part of the storage part 12 functions as a storage space 12a, in which the electronic device 7, the wedge part 13 and the plate part 14 are stored. The storage unit 12 is substantially rectangular in a front view shown in FIG. 4, and the circumference of the inner circumference of this rectangle is shorter than the circumference of the opposing surface of the electronic device. On the bottom surface of the storage portion 12, a protruding portion 12 b that protrudes inward in the Z direction shown in FIG. 4 is formed. The protrusion 12b is formed in each of the pair of openings 12c.

  The storage portion 12 is preferably made of a material having high rigidity, and for example, a sheet-like composite material reinforced with metal or organic fiber in the circumferential direction can be used. By using such a composite material, it is possible to reduce the weight while maintaining the rigidity. Moreover, it is desirable that the storage portion 12 is made of metal and has a seamless cylindrical shape. According to the storage portion having such a configuration, a large tightening force for the electronic device 7 can be obtained with a small amount of expansion by utilizing a specific rigidity higher than that of rubber.

  The width of the wedge portion 13 in the Y direction is shorter than the width of the storage portion 12 and the electronic device 7 in the Y direction, and is engaged with the electronic device 7 at the center of the electronic device 7 in the Y direction. The electronic device 7 is formed with a recess 7c (uneven portion) with which the wedge portion 13 is engaged. The recess 7c extends along the insertion direction XA. The recessed portion 7 c is configured such that the wedge portion 13 is inserted, and the depth of the recessed portion 7 c changes with the thickness of the wedge portion 13. Specifically, in the portion where the wedge portion 13 is thick, the recess portion 7c is deep, and in the portion where the wedge portion 13 is thin, the recess portion 7c is shallow. The upper surface 7b of the electronic device 7 (the surface on which the recess is not formed) is parallel to the bottom surface 7a of the electronic device 7, but the bottom surface of the recess 7c is inclined with respect to the bottom surface of the electronic device 7. Yes.

  The wedge portion 13 includes a front end portion 13 a that becomes a front end when inserted into the storage portion 12 and a rear end portion 13 b that becomes a rear end when inserted into the storage portion 12. The insertion direction of the wedge portion 13 is along the X direction in the drawing, and FIG. 3 shows the insertion direction as XA and the insertion direction as XB. The wedge portion 13 changes in thickness along the insertion direction XA, and the thickness at the rear end portion 13b is thicker than the front end portion 13a. The upper surface of the wedge portion 13 is along the inner surface of the storage portion 12 and is substantially parallel to the X direction. The bottom surface of the wedge portion 13 is an inclined surface 13c that faces the recessed portion 7c of the electronic device 7 and is inclined with respect to the tire width direction twd. The inclined surface 13c of the wedge portion 13 and the bottom surface of the recessed portion 7c of the electronic device 7 are configured to engage with each other.

  The plate portion 14 as the restricting portion is joined to the inclined surface 13 c of the wedge portion 13 and is integrated with the wedge portion 13. The plate portion 14 engages with at least one of the storage portion 12 and the electronic device 7 in a state where the electronic device 7 and the wedge portion 13 are fitted, and the wedge from the storage portion 12 to the outside of the storage portion 12 is engaged. The movement of the part 13 is restricted.

  The plate portion 14 extends along the insertion direction XA, and protrudes outward from at least one of the storage portion 12 and the electronic device 7 when the wedge portion 13 is inserted into the storage portion 12. It is configured. The distal end portion 14a in the insertion direction XA of the plate portion 14 is configured to be deformable in a direction intersecting the insertion direction XA. When the front end portion 14a of the plate portion 14 is bent, the front end portion 14a of the plate portion 14 and the electronic device 7 are caught, and the wedge portion 13 located in the storage portion 12 moves outside the storage portion 12. Can be regulated.

(3) Attaching Mode of Electronic Device Next, a mounting mode of the electronic device 7 to the tire 1 using the electronic device mounting device will be described. FIG. 6 is a view for explaining an attachment mode of the electronic device 7 to the tire 1 using the electronic device attachment device. When the electronic device 7 is attached to the tire 1, the pedestal portion 11 integrated with the storage portion 12 is fixed to the inner liner 4 of the tire 1. Next, the electronic device 7 is stored in the storage unit 12.

  The wedge portion 13 is placed on the recessed portion 7c of the electronic device 7, and the wedge portion 13 is moved in the insertion direction XA along the recessed portion 7c from the distal end side of the wedge portion 13. FIG. 6A is a view showing a state in which the wedge portion 13 is inserted. The height of the storage space of the storage portion 12 at the center position in the Y direction (the length in the Z direction) is the height of the wedge portion 13 and the electronic device 7 in a state where the wedge portion 13 and the electronic device 7 are fitted (Z (Length in the direction). Therefore, the upper surface of the wedge portion 13 comes into contact with the inner surface of the storage portion 12 in a state before the tip portion 13 a of the wedge portion 13 is inserted to the outer surface of the electronic device 7. FIG. 6A shows a state in which the upper surface of the wedge portion 13 is in contact with the inner surface of the storage portion 12, and the inner surface of the storage portion 12 before deformation is illustrated as X1.

  When the wedge portion 13 is further moved in the insertion direction XA from the state of FIG. 6A, the state shown in FIG. 6B is obtained. The wedge part 13 moves along the recessed part 7c. Specifically, the wedge portion 13 moves toward the upper side in FIG. 6 while moving toward the distal end side in the insertion direction XA. Therefore, the inner surface X1 of the storage portion 12 is pressed upward by the wedge portion 13 and deformed upward. In FIG. 6B, the inner surface of the storage portion after deformation is shown as X2, and the deformation amount of the storage portion is shown as Δ1. As shown in FIG. 6B, after the wedge portion 13 is inserted until the wedge portion 13 and the outer surface of the electronic device 7 are substantially flush with each other, the front end portion 14a of the plate portion 14 is folded back to the electronic device 7 side. The tip portion 14a of the plate portion 14 is caught by the electronic device 7, and the movement of the wedge portion 13 in the insertion direction XB is restricted.

  On the other hand, when taking out the electronic device 7 from the storage part 12, the tip part 14a of the plate part 14 once bent is deformed from a bent state to a flat state along the inclined surface 13c. Thereby, since the front-end | tip part 14a of the plate part 14 is not caught in the electronic device 7, the wedge part 13 can be moved to the insertion direction XB, and the electronic device 7 can be removed.

(4) Operation / Effect According to the electronic device mounting apparatus 10 according to the present invention, the wedge portion 13 and the electronic device 7 are recessed by inserting the wedge portion 13 in a state where the electronic device 7 is disposed in the storage portion 12. The electronic device 7 can be fastened and fixed in the storage portion 12 by fitting with the portion 7c. Compared to the case of fixing by rubber tension like a rubber patch, the tightening force on the tire surface can be increased, and the adhesion force of the electronic device to the tire surface can be increased.

  Each of the openings 12c of the storage part 12 is formed with a protruding part 12b. Since the electronic device 7 is sandwiched between the projecting portions 12b in the insertion direction, movement along the insertion direction is restricted, and positional displacement is prevented. When the wedge portion 13 is inserted to a predetermined position, the wedge portion 13 presses the inner surface of the storage portion in a direction in which the storage portion 12 is expanded. The storage portion 12 is deformed in a direction to widen the storage space by the wedge portion 13, and the electronic device 7 is firmly fixed in the storage portion 12 by the reaction force.

  Further, in a state where the electronic device 7 is firmly fixed in the storage portion, the position of the wedge portion 13 is fixed by bending the tip portion 14a of the plate portion 14 integrated with the wedge portion 13 toward the electronic device 7 side. Is done. Therefore, the position shift of the wedge part 13 can be suppressed, and the electronic device 7 once fixed in the storage part 12 can be prevented from going out of the storage part 12.

  Further, since the electronic device 7 is fixed to the storage portion 12 by fitting the electronic device 7 and the wedge portion 13 in the storage space of the storage portion 12, the shape varies depending on the shape of the wedge portion 13. It is possible to mount the electronic device 7 having a height or shape. Therefore, the versatility of the electronic device mounting apparatus can be enhanced.

(5) Other Embodiments Next, an electronic device mounting apparatus according to a modification will be described. In the description of the electronic device mounting apparatus according to the following modification, the same components as those in the above-described embodiment will be described using the same reference numerals.

  7 and 8 are cross-sectional views showing an electronic device mounting apparatus 10A according to the first modification. An electronic device mounting apparatus 10 </ b> A according to Modification 1 includes an auxiliary wedge portion 15 disposed between the wedge portion 13 and the electronic device 7. The auxiliary wedge portion 15 includes a front end portion 15 a that becomes a front end when inserted into the storage portion 12, and a rear end portion 15 b that becomes a rear end when inserted into the storage portion 12.

  The auxiliary wedge portion 15 changes in thickness along the insertion direction XA, and is thinner on the rear end portion side of the auxiliary wedge portion 15 than on the front end portion side of the auxiliary wedge portion 15. The upper surface of the auxiliary wedge portion 15 is an inclined surface 15 c along the inclined surface 13 c of the wedge portion 13. The bottom surface 15 d of the auxiliary wedge portion is disposed along the recessed portion 7 c of the electronic device 7. Unlike the embodiment, the recess 7 of the electronic device 7 is formed along the bottom surface of the electronic device 7 and is horizontal to the insertion direction.

  Between the electronic device 7 and the auxiliary wedge portion 15, an auxiliary plate portion 16 as a restricting portion is disposed. The auxiliary plate portion 16 is joined to the bottom surface 15d of the auxiliary wedge portion 15 and extends along the insertion direction XA. The rear end portion 16b in the insertion direction of the auxiliary plate portion 16 is bent in a direction crossing the insertion direction XA. The rear end portion 16b is in contact with the outer surface of the electronic device 7 and restricts movement in the direction along the insertion direction XA of the electronic device.

  Further, a groove into which the plate portion 14 is inserted may be formed on at least one of the surface of the wedge portion 13 on the auxiliary wedge portion 15 side and the surface of the auxiliary wedge portion 15 on the wedge portion 13 side. By forming the groove, when the wedge portion 13 is slid with respect to the auxiliary wedge portion 15, the positional deviation between the wedge portions can be suppressed.

  Next, an electronic device mounting apparatus 10B according to Modification 2 will be described with reference to FIGS. 9 and 10 are cross-sectional views showing an electronic device mounting apparatus 10B according to the second modification. The electronic device mounting apparatus 10B according to the modification 2 includes the auxiliary wedge portion 15 and the auxiliary plate portion 16 similarly to the electronic device mounting apparatus 10A according to the modification 1, but the electronic device mounting apparatus 10A according to the first modification. And the configuration of the plate part is different. Since the configuration other than the plate portion is the same as that of the first modification, the description thereof will be omitted by using the same reference numerals.

  The plate part 14 according to the modification 2 is bent in a direction in which the rear end part 14b in the insertion direction intersects the insertion direction XA. The rear end portion 14b is in contact with the outer surface of the electronic device 7 and restricts movement of the electronic device 7 in the direction along the insertion direction XA. Further, the plate portion 14 according to the modified example 2 is not joined to the wedge portion 13, and is configured separately from the wedge portion 13.

  When the electronic device 7 is attached to the tire 1 using the electronic device mounting apparatus configured as described above, first, the pedestal portion 11 integrated with the storage portion 12 is fixed to the inner liner 4 of the tire 1. Next, the electronic device 7 is stored in the storage unit 12. Next, after placing the auxiliary plate portion 16 in the recessed portion 7 c of the electronic device 7, the auxiliary wedge portion 15 is placed, and the auxiliary wedge portion 15 and the recessed portion 7 c of the electronic device 7 are fitted.

  Then, after placing the plate portion on the auxiliary wedge portion 15, the wedge portion 13 is moved in the insertion direction along the auxiliary wedge portion 15. FIG. 10A is a view showing a state in which the wedge portion 13 is inserted. The height of the storage space (the length in the Z direction) of the storage part at the center position in the Y direction is the wedge part 13, the auxiliary wedge part 15, and the wedge part 13, the auxiliary wedge part 15, and the electronic device 7. It is formed shorter than the height (the length in the Z direction) of the electronic device 7. Therefore, the upper surface of the wedge portion abuts against the inner surface of the storage portion in a state before the distal end portion 13a of the wedge portion 13 is inserted to the outer surface of the electronic device.

  The wedge part 13 moves along the inclined surface 15 c of the auxiliary wedge part 15. Therefore, the inner surface of the storage portion is pressed upward by the wedge portion and deformed upward. The storage portion is deformed in a direction to widen the storage space by the wedge portion, and the electronic device is firmly fixed by the storage portion by the reaction force.

  When the wedge portion 13 is inserted until the wedge portion and the outer surface of the electronic device are substantially flush with each other, the rear end portion 14 b of the plate portion comes into contact with the outer surface of the electronic device 7. In this state, the tip end portion 14a of the plate portion 14 is folded back to the electronic device 7 side. Since the front end portion 14a of the plate portion 14 is hooked on the electronic device 7 and the rear end portion 14b of the plate portion is hooked on the electronic device 7, the movement of the wedge portion 13 in the insertion direction XB and the movement in the insertion direction XA is restricted. Is done.

  On the other hand, when taking out the electronic device 7 from the storage part 12, the tip part 14a of the plate part 14 once bent is deformed from a bent state to a flat state along the inclined surface 13c. Thereby, since the front-end | tip part 14a of the plate part 14 is not caught in the electronic device 7, the wedge part 13 can be moved to the insertion direction XB, and the electronic device 7 can be removed.

  Next, an electronic device mounting apparatus 10C according to Modification 3 will be described with reference to FIG. FIG. 11 is a cross-sectional view illustrating an electronic device mounting apparatus 10C according to Modification 3. The electronic device mounting apparatus 10C according to the modified example 3 is different from the electronic device mounting apparatus according to the above-described embodiment in the configuration of the storage unit. Since the configuration other than the storage unit is the same as that of the embodiment, the description is omitted by using the same reference numerals.

  The storage unit 12 according to Modification 3 is configured by bending a plate-shaped metal plate into a cylindrical shape. In the storage unit 12, the first end 12 e located at the upper end and the second end 12 f disposed below the first end 12 e are not joined in the cross-sectional view shown in FIG. 11. , Are spaced apart at a certain distance. A rubber portion 17 as an elastic member is disposed between the first end portion 12e and the second end portion 12f of the storage portion 12.

  The rubber portion 17 is elastically deformed by being pressed by an external force, and is compressed when the storage portion 12 pressed by the wedge portion is deformed outward. The electronic device 7 in the storage portion 12 can be firmly fixed by the urging force of the rubber portion 17. The storage unit 12 according to the modified example 3 is less rigid in the expansion direction than the storage unit of the embodiment, and the tightening force of the electronic device with respect to the insertion volume of the wedge unit 13 is reduced. Therefore, the tightening force for the electronic device can be adjusted.

  Although the contents of the present invention have been disclosed through the embodiments of the present invention as described above, it should not be understood that the descriptions and drawings constituting a part of this disclosure limit the present invention.

  For example, the plate portion is joined to the wedge portion and integrated with the wedge portion, and the auxiliary plate portion is joined to the auxiliary wedge portion and integrated with the auxiliary wedge portion, but the plate portion and the auxiliary plate portion are It is not necessary to be integrated with the wedge portion and the auxiliary wedge portion without being joined to the wedge portion and the auxiliary wedge portion.

  For example, when the electronic device is removed from the tire, for example, when the electronic device is replaced, the front end portion of the plate portion or the like once bent is bent in a horizontal state. It is conceivable that the metal parts once bent have become brittle due to work hardening. By making the plate part etc. separate from the wedge part, it is possible to replace only the plate part. Compared to the case where the wedge part and the plate part are integrated, the replacement is possible. The number of parts can be reduced.

  In the present embodiment, the concave portion is formed in the electronic device as the concave and convex portion formed on the relative surfaces where the electronic device and the wedge portion face each other. A concave portion that fits into the convex portion may be formed in the wedge portion, or an uneven portion may be formed in the electronic device, and an uneven portion that meshes with the uneven portion may be formed in the wedge portion.

  From this disclosure, various alternative embodiments, examples and operational techniques will be apparent to those skilled in the art.
