DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
<First Embodiment> The structure of the vehicle body cylindrical cavity filled with the foam filling member of the present invention is a foam which is foamed by heating to close the inside of the cylindrical cavity including the pillar of the vehicle body, It is comprised from the holder part holding this foam. FIG. 1 shows a holder part of the foam filling member according to the first embodiment of the present invention in a front view, and FIG. 2 shows the holder part in a side view.
[0016]
In the figure, a holder portion 11 formed of a polyamide-based synthetic resin such as nylon is configured so that a pair of sandwiching plates 11a and 11b having a substantially square shape face each other with an interval substantially equal to the thickness of the foam 12. Are connected by a connecting portion 11c, and an engaging piece 11d for engaging and fixing to the vehicle body is provided on the surface of one holding plate 11a opposite to the other holding plate 11b. Here, the connecting portion 11c is formed in a columnar shape so as to be connected at the central portion of the sandwiching plates 11a and 11b, and on the diagonal line of the inner surface of the sandwiching plate 11b as shown in FIG. Small protrusions 11b1 are formed at four positions in total.
[0017]
On the other hand, the foam 12 has a thickness that allows forcible insertion between the sandwiching plates 11a and 11b, and is formed in a substantially square shape. And it assumes that it will become one set by mounting | wearing 4 pieces with respect to the one holder part 11, At least 1 corner | angular part is notched so that it may not interfere with the said connection part 11c.
[0018]
That is, as shown in FIG. 3, when the foam 12 is pushed in from the four diagonally outer sides between the both sandwiching plates 11a and 11b, the four foams 12 are arranged around the central connecting portion 11c. And in this state, as shown in FIG. 4, each small protrusion 11b1 bites into each foam 12 so that it does not come off easily.
[0019]
On the other hand, the engaging piece 11d has a substantially octagonal prism shape, and as shown in FIG. 2, convex portions 11d1 and 11d1 projecting in the radial direction are formed on the two peripheral surfaces of the tip portion and opposite to each other. The distance between the convex portion 11d1 and the sandwiching plate 11a is approximately the same as the thickness of the wall material of the vehicle body. FIG. 5 shows an operation process for mounting the holder portion 11 to the rectangular engagement hole 13 formed on the vehicle body side, as shown in FIG. The distance between the wall surfaces facing the side is equal to the length of one side of the engagement hole 13 formed on the vehicle body side.
[0020]
Therefore, when inserting the engaging piece 11d in the holder portion 11 so as to face the engaging hole 13, the holder portion 11 is inclined 45 degrees with respect to the engaging hole 13 as shown by a two-dot chain line in FIG. The projections 11d1 and 11d1 are pushed so as to pass through the gaps at the corners of the engagement holes 13 so as to face each other. The convex portion 11d1 is sized so as to enter the gap.
[0021]
When the engaging piece 11 d is pushed into the engaging hole 13, the four wall surfaces of the octagonal prism are almost in contact with the four sides of the engaging hole 13 and cannot rotate freely. However, if it is forcibly rotated 45 degrees as shown by the chain line in FIG. 5 from this state, it can be rotated while being slightly bent by the elasticity of the engaging piece 11d itself. At this position, the remaining four wall surfaces substantially abut against the four sides of the engagement hole 13 and do not return freely. Furthermore, since the projections 11d1 and 11d1 formed by being separated from the sandwiching plate 11a by the thickness of the vehicle body member sandwich the edge of the engagement hole 13 between the sandwiching plate 11a, the engagement piece 11d is It does not come out of the engagement hole 13.
[0022]
That is, in the insertion operation, the engaging piece 11d is linearly moved in the axial direction, and when the clamping plate 11a hits the vehicle body, it is rotated 45 degrees in a plane orthogonal to the axial direction as a reference, and the convex portion 11d1 and the vehicle body member Are engaged. Therefore, the convex portion 11d1 is not bent and retracted during the insertion operation, but the convex portion 11d1 has a rigid configuration, so that it can be firmly fixed.
[0023]
In the present embodiment, when the foam body 12 is supported by the holder portion 11, the corners of the foam body 12 are sandwiched. However, the support methods for the foam body 12 are extremely diverse and have been described above. It goes without saying that it is not limited to things.
[0024]
Moreover, although the engagement piece 11d of the holder part 11 is made into an octagonal column shape, it is only an example on the assumption that the engagement hole 13 is square, and after performing an insertion operation toward the engagement hole on the vehicle body side The convex portion that has already passed through the engagement hole by rotating it may wrap around the rear side of the vehicle body member and be clamped. Therefore, various modifications are possible depending on the degree of freedom of the shape of the engagement hole. In addition, with respect to the configuration that prevents easy rotation in the engaged state, it is also possible to form a recess or the like on the side of the vehicle body member so that the projection easily fits in.
[0025]
<Second Embodiment> FIG. 6 is a side view showing a holder portion 21 according to a second embodiment of the present invention. In this example, the engagement piece 21d of the holder portion 21 projects toward the engagement hole 23 on the vehicle body side, and the hook 21d1 that can be engaged with the edge portion of the engagement hole 23 by bending the tip 90 degrees. And when the hook 21d1 is inserted into the engagement hole 23 and then moved so as to be hooked close to the edge, from the edge on the opposite side of the engagement hole 23. A misalignment prevention protrusion 21d2 is provided to prevent entry and return in the reverse direction. In addition, spring pieces 21d3 and 21d3 that protrude from the side surface of the engagement piece 21d toward the peripheral edge of the engagement hole 23 and are biased in the opposite direction are also formed. The other structure of the holder portion 21, that is, the sandwiching pieces 21a and 21b and the connecting portion 21c are the same as those in the first embodiment, and the description thereof is omitted.
[0026]
In the present embodiment configured as described above, the hook 21 d 1 of the engagement piece 21 d is inserted into the engagement hole 23, and the tip is shifted so as to be caught by the edge of the engagement hole 23. Of course, the operation in the insertion direction and the operation for shifting are orthogonal to each other. When shifting, another slip prevention protrusion 21d2 formed on the engagement piece 21d hits the surface of the vehicle body member, and the tip of the hook 21d1 is not caught on the edge of the engagement hole 23 without being caught. The slip prevention protrusion 21 d 2 cannot enter the engagement hole 23. However, if the displacement force is increased so that the displacement prevention projection 21d2 enters the engagement hole 23, the tip of the hook 21d1 bends, so that the displacement prevention projection 21d2 can enter the engagement hole 23. Thus, the engagement piece 21d itself can be pushed deeply into the engagement hole 23, so that the tip of the hook 21d1 is caught by the edge of the engagement hole 23.
[0027]
Further, during this operation, the spring pieces 21d3 and 21d3 act so as to abut against the vehicle body member and push them back, and continue to give a moderate tensile force with the hook 21d1 engaged, preventing rattling, I will try to prevent it from coming off.
[0028]
In this way, after the first insertion operation of the engagement piece, the vehicle body member is held by shifting it in a direction orthogonal to the engagement piece, and once it is held, it is prevented from being removed by the slip prevention protrusion. Of course, this structure itself can adopt various specific shapes, and may be provided with two hooks.
[0029]
<Third Embodiment> FIG. 8 shows a side view of a holder portion 31 according to a third embodiment of the present invention. In this example, the engagement piece 31d is formed in a cylindrical shape with a tip crack, and a wedge-shaped projection 31d2 protruding from the front end outer surface of each tip crack piece 31d1 is formed. In this case, the engagement piece 31d is also substantially coincident with the inner diameter of the engagement hole 33, and since there is the wedge-shaped projection 31d2, when the engagement piece 31d is inserted into the engagement hole 33 on the vehicle body side, 31d1 bends inwardly.
[0030]
On the other hand, the connecting portion 31c in this case has the same diameter as that of the engaging piece 31d, and a through hole 31e penetrating both is formed, and a cylindrical fitting pin 31f is inserted therein. It is. Here, the fitting pin 31f is inserted from the connecting portion 31c side to the engaging piece 31d side, and at the beginning, the tip thereof is held at the temporary support position not reaching the engaging piece 31d and further pushed. The tip can be moved to the main support position where it enters the inside of the engagement piece 31d. A small protrusion 31e1 is formed on the inner surface of the through hole 31e so as to be held at both positions, and two tubular grooves 31f1 are formed on the outer peripheral surface of the fitting pin 31f.
[0031]
When this holder portion 31 is used, the engaging piece 31d is inserted into the engaging hole 33 with the fitting pin 31f held at the temporary support position, and the clamping plate 31a is disposed on the vehicle body side as shown in FIG. At the point of contact with the member, the fitting pin 31f is pushed into the main support position. When the fitting pin 31f is in the temporary support position, even if the wedge-shaped protrusion 31d2 hits the edge of the engagement hole 33, each tip crack 31d1 can bend inwardly, and the wedge-shaped protrusion 31d2 can be operated in the engagement hole 33. If the fitting pin 31f is pushed in when it passes, it will become a pinch shape.
[0032]
That is, following the operation of inserting the engagement piece 31d, an engagement operation of pushing the fitting pin 31f is performed. Even in this case, the holder portion 31 cannot be easily pulled out from the engagement hole 33. In this embodiment, the sandwiching plate 31a becomes a substantial flange piece, and the vehicle body side member is sandwiched together with the wedge-shaped protrusion 31d2. In the embodiments so far, a simple structure is shown in which the corner portion of the foam is sandwiched and supported by the holder portion, but it goes without saying that various modifications are possible. An example will be described.
[0033]
<Fourth Embodiment> FIG. 10 is a perspective view showing a holder portion 41 according to a fourth embodiment of the present invention, and FIG. 11 schematically shows the operation principle thereof. In addition, in FIG. 10, although the part of the engagement piece is simply shown with the broken line, what is necessary is just to apply the various modifications mentioned above.
[0034]
In the holder portion 41, the two foams 42 are sandwiched and held by the sandwiching plates 41a and 41b, but grooves 41b1 and 41b1 are formed on the sandwiching plate 41b on the side opposite to the vehicle body side member so as to be easily bent. is there. Since the volume of the foam 12 increases during foaming, the sandwiching plates 41a and 41b are pushed and opened. Using this force, it is possible to bend the tip portions of the sandwiching plates 41a and 41b at the grooves 41b1 and 41b1. Then, as shown in FIG. 11, a closed space is formed in the cylindrical hollow portion 44 of the vehicle body by the sandwiched clamping plates 41a and 41b. In addition, it is set as the structure provided with the engagement piece 41d for engaging and fixing to a vehicle body in the surface on the opposite side to the other clamping plate 41b in one clamping plate 41a.
[0035]
In this way, since the volume in the cylindrical cavity 44 to be filled with the foam 42 is reduced, the foam 42 can be closed while reducing the amount of use. Also, the vacancy improves the vibration isolation effect. That is, not only is the cylindrical cavity 44 closed, but there is also an effect as a surge tank that avoids pressure by forming an independent vacancy in the middle. In order to make the sandwiching plate 41b bend easily, it is not limited to the groove 41b1, but may be a thin piece or a perforation.
[0036]
<Fifth Embodiment> FIG. 12 is a perspective view showing a holder portion 51 according to a fifth embodiment of the present invention, and FIG. 13 schematically shows the operation principle thereof. In FIG. 12, the engagement piece portion is simply indicated by a broken line. In this embodiment, the lower portions of the foam 52 are sandwiched and held by the sandwiching plates 51a and 51b, and grooves 51a1 and 51b1 are formed in the respective outer portions so that the tips can be easily opened. The plates 51a and 51b themselves are held by the part from the center of the cylindrical cavity 54. In addition, it is set as the structure provided with the engagement piece 51d for engaging and fixing to a vehicle body in the surface on the opposite side to the other clamping plate 51b in one clamping plate 51a.
[0037]
Also in this example, as shown in FIG. 13, the tip portions of the sandwiching plates 51a and 51b are expanded by the pressure when the foam 52 is foamed. In this case, the cylindrical hollow portion 54 is closed by the sandwiching plates 51a and 51b itself by being spread. Although the sandwiching plate 51a leaves a gap when it is closed by 51b, the foamed body 52 foams and spreads on the sandwiching plate 51a. Therefore, even when the cylindrical cavity portion 54 is oriented in the vertical direction, the sandwiching plate 51a hangs downward. There is no such thing.
[0038]
<Sixth Embodiment> FIG. 14 is a perspective view showing a holder portion 61 according to a sixth embodiment of the present invention, and FIG. 15 schematically shows the operation principle thereof. In FIG. 14, the engagement piece portion is simply indicated by a broken line.
[0039]
In this embodiment, sandwiching plates 61 a and 61 b are formed so as to wrap the foam 62. That is, starting from the engagement piece 61d, one holding plate 61a extends to the back side along the upper side of the foam 62 while extending upward, and the other holding plate 61b extends to the back side along the lower side of the foam 62 while extending downward. It is going around. And both the clamping plates 61a and 61b are formed with grooves 61a1 and 61b1 at the portions around the foam 62.
[0040]
When the sandwiching plates 61a and 61b are formed so as to wrap the foam 62 in this way, when the volume of the foam 12 is increased, the tip portions of both sandwiching plates 61a and 61b are pushed open as shown in FIG. As a result, the volume increases through the pushed gap. Therefore, it becomes easy to guide the direction in which the foam 62 swells in one direction, and it is possible to fill a necessary portion in the cylindrical cavity 64 with the minimum foam 62. In addition, it is set as the structure provided with the engagement piece 61d for engaging and fixing to a vehicle body in the surface on the opposite side to the other clamping plate 61b in one clamping plate 61a.
[0041]
<Seventh Embodiment> FIG. 16 is a perspective view showing a foam filling member 70 according to a seventh embodiment related to the present invention, and FIG. 17 schematically shows the operation principle thereof. If the cylindrical hollow portion of the vehicle body is formed in a straight line at a certain portion, the cylindrical hollow portion 84 can be very efficiently obtained by closing the top and bottom with two plates and filling the foam between them. And can be filled.
[0042]
In the present embodiment, an upper lid 71 a and a lower lid 71 b that are capable of closing the cylindrical cavity 84 and slidable in the vertical direction are fixed so as to be connected by a cylindrical foam 72. In this case, cylindrical recesses 71a1 and 71b1 are formed on the inner side surfaces of the upper lid portion 71a and the lower lid portion 71b to insert and fix the end portions of the foam 72, and the small projections 71a2 for engagement are formed on the inner surfaces thereof. , 71b2 are formed.
[0043]
The integrally formed foam filling member 70 is normally inserted into the hollow portion, but as shown in FIG. 17, the vehicle body side member restricts the free movement of the foam filling member 70 in the vertical direction. If the nail | claw 75 is formed, it can hold | maintain reliably in arbitrary positions. Further, when the foam 72 is foamed by heating, the foam 72 is foamed between the upper lid portion 71a and the lower lid portion 71b, and the volume increases to push up and open the upper lid portion 71a and the lower lid portion 71b. The hollow portion 74 can be closed.
[0044]
On the other hand, even in this case, the engagement pieces 11d to 61d described above are formed in the upper lid portion 71a and the lower lid portion 71b, and the engagement pieces 71d are engaged and fixed to the engagement holes 73 on the vehicle body side. This is substantially an embodiment of the present invention.
[0045]
<Eighth Embodiment> In the previous embodiment, the foam 72 has a cylindrical shape, but in this embodiment, the cylindrical recesses 81a1 and 81b1 formed in the upper lid portion 81a and the lower lid portion 81b are provided. It is formed to be one size larger, and one enters the other to form a vacant chamber. By forming vacancies in this way, the foam 82 need not be in the form of a column or plate, and can be used in the form of a so-called pellet. On the other hand, even in this case, if the upper cover 81a and the lower cover 81b are engaged and fixed in the engagement hole 83 on the vehicle body by the engagement piece 81d, the embodiment of the present invention is substantially obtained.
[0046]
<Ninth Embodiment> FIG. 20 is a perspective view showing a foam filling member 90 according to a ninth embodiment of the present invention, and FIG. 21 schematically shows the operation principle thereof. In this embodiment, a bottomed cylindrical first case 91a and a second case 91b are combined with each other with their openings facing each other, and a foam 92 is accommodated therein. In the combined state, it is fixed to the vehicle body member via the engagement piece 91d, and when heated, the volume of the foam 92 increases and acts to push out the second case 91b.
[0047]
In this case, a gap or a hole is formed in the first case 91a and the second case 91b, and when there is no room for the first case 91a and the second case 91b to swell in the cylindrical cavity, the foam 92 is released from the gap. The cylindrical cavity 94 may be substantially closed by leaking out.
[0048]
In this way, by guiding the direction in which the first case 91a and the second case 91b are first expanded by the expansion / contraction box portion, it is possible to close the necessary portion with a minimum volume. In the present embodiment, the engagement piece 91d formed in the first case 91a is engaged and fixed in the engagement hole 93 on the vehicle body side.
[0049]
<Tenth Embodiment> FIG. 22 shows a modification of the ninth embodiment. In this example, the first case 101a and the second case 101b constituting the expansion / contraction box part are connected by the connection part 101c to increase the expansion / contraction length. In the present embodiment, the engagement piece 101d formed in the first case 101a is engaged and fixed in the engagement hole 103 on the vehicle body side.
[0050]
<Eleventh Embodiment> FIG. 23 is a perspective view showing the holder 111 and the foam 112 according to the eleventh embodiment of the present invention, and FIG. 24 schematically shows the operation principle thereof. ing. In FIG. 23, the engagement piece portion is simply indicated by a broken line.
[0051]
In this embodiment, the holder portion 111 is formed like a core material, and the foam 112 is inserted into the core material and held as a columnar shape. In this example, the cylindrical cavity can be sufficiently closed as required with a simple configuration. In this case, the cylindrical cavity can be efficiently closed by supporting the foam 112 as close to the center of the cylindrical cavity as possible with the holder 111. Also in this embodiment, the engagement piece 111d is engaged and fixed in the engagement hole 113 on the vehicle body side.
[0052]
<Twelfth Embodiment> FIG. 25 is a perspective view showing a holder 121 according to a twelfth embodiment of the present invention, and FIG. 26 schematically shows the operation principle thereof. In FIG. 25, the engagement piece portion is simply indicated by a broken line.
[0053]
In the present embodiment, the holder portion 121 is formed in a so-called tray shape (tray), and the foam 122 is placed on and supported on the tray. Then, the tray is oriented so as to close the cylindrical cavity 124 by engaging and fixing to the engagement hole 123 on the vehicle body side in the cylindrical cavity 124 using various engagement pieces 121d. ing. Since the tray is used, the edge is raised, and even when the foam 122 is softened, it can be prevented that the foam 122 hangs down from the gap.
[0054]
<Thirteenth Embodiment> FIG. 27 uses a holder portion 131 that is substantially the same shape as the holder portion 121, but holds the foam 132 having a large expansion rate in the center of the cylindrical cavity portion 134 as much as possible. . In this example, a core part 131a is formed on the central upper surface of the tray, and a cylindrical foam 132 is inserted and supported from above. Also in this example, the engagement piece 131d is used to engage and fix in the engagement hole 133 on the vehicle body side in the cylindrical cavity 134.
[0055]
<Fourteenth Embodiment> FIG. 28 similarly uses a tray-like holder portion 141, but does not use an engaging piece, but includes a claw-like portion 143 protruding from the body member side. This is an example in which an engagement recess 141d is formed.
[0056]
<Fifteenth Embodiment> In the above embodiments, the holder part and the foam are separately formed. However, they can be formed by combining them. 29 to 31 show a foam filling member 150 according to the fifteenth embodiment of the present invention. The foam filling member 150 of the present embodiment is configured by kneading a photo-curing resin in addition to a foam constituent material composed of a resin and a foaming agent, and is loaded with the foam 122 in the tray-shaped holder portion 121 described above. Then, the outer surface is cured by irradiating ultraviolet rays having a predetermined wavelength from the surroundings with the upper surface facing downward.
[0057]
FIG. 30 shows the foam filling member 150 in a side view, but the outer peripheral surface is substantially cured by irradiating ultraviolet rays of a predetermined wavelength except for the upper surface, and the foam 122 placed on the holder part 121 is applied to the foam 122. Only the relevant part remains uncured. Therefore, as shown in FIG. 31, when the engagement piece 150d is heated while being engaged with and fixed to the engagement hole 153 of the cylindrical cavity 154, the uncured portion is foamed, which is the case of the twelfth embodiment. It is possible to close a predetermined space in the same manner as described above.
[0058]
<Sixteenth Embodiment> Also in this embodiment, an example is shown in which the holder portion and the foam are not formed separately, but are formed integrally. 32 to 33 show a foam filling member 160 according to the sixteenth embodiment of the present invention. The foam filling member 160 of the present embodiment is configured by kneading one of the resin materials to be mixed and cured in addition to the resin and the above-described foam constituent material, and after forming into a predetermined shape, a thin vinyl on the upper surface Sheets 161 are overlaid.
[0059]
After molding, as shown in FIG. 33, only the outer surface is cured by dipping in the other solution of the resin material to be cured. However, since the vinyl sheet 161 is stuck on the upper surface, it is not cured.
[0060]
When the outer peripheral surface is cured in this way, as shown in FIG. 34, when the engagement piece 160d is engaged and fixed in the engagement hole 163 of the cylindrical cavity 164 and heated, the uncured portion is foamed. In this case, since the vinyl sheet 161 on the surface is sufficiently thin, it is softened by heat and allowed to foam.
