In this way, when a large load transmitted from the window glass is applied to the pillar body provided in the high-speed vehicle due to the impact force due to the bird collision and the pressure fluctuation when passing through the tunnel, a bending moment that tends to bend inward is generated in the pillar body, and A couple is generated in a portion where both ends of the pillar body in the frame are integrated and continuous. That is, when the load is transmitted from the pillar main body to the window frame, the reinforcing member and the partition wall are provided at the portion where the pillar main body is continuous, so that the load transmitted to the window frame is supported by the reinforcing member and the partition wall. This makes it possible to withstand with great strength the load acting on the window frame from the pillar body, and ensure the large load acting on the pillar body from the window glass due to the impact force due to bird collision and the pressure fluctuation when passing through the tunnel. It is possible to support the window glass with great strength by transmitting it to the window frame and resisting the load by this window frame. Since the composite material including the high elastic fiber has high fatigue strength, the problem of structural fatigue that cannot be prevented by the metal material does not occur in the window frame. As described above, the pillar frame can be supported and the window glass can be supported with great strength by the window frame of the high-speed vehicle made of the composite material and the foamed synthetic resin that does not cause structural fatigue.

The problem that the window frame needs to have a large strength due to the distribution of the load from the main body to the window frame can be prevented.

According to a fourth aspect of the present invention, a reinforcing sheet made of the composite material is attached to a base end portion of the pillar body that abuts on the window frame and a region around the base end portion of the window frame. It is characterized by

According to the invention, since the strength of the mounting portion of the pillar main body to the window frame is improved by the reinforcing sheet, the deformation amount of the mounting portion can be made equal to that of the window frame, and the structural fatigue can be reduced. Suppress and prevent damage from occurring.

The present invention according to claim 5 is characterized in that a holding member for pressing and holding the window glass from the outside is detachably connected to the window frame by a screw member.

According to the invention, since the pressing member is detachably connected to the window frame by the screw member, a part of the load acting on the pressing member is directly transmitted to the window frame via the screw member. As a result, the load transmitted from the pressing member to the pillar body is reduced, and the cross-sectional shape of the pillar body can be reduced.

According to the present invention of claim 6, the pressing member is
It is characterized in that it has a mounting portion which is arranged on the window frame and has a width wider than a portion for pressing the window glass, and the mounting portion is detachably connected to the window frame by a plurality of screw members. .

It is easy, and the processing cost is low compared to the case of processing a metal such as an aluminum alloy. Therefore, a design close to the shape of the conventional metal interior decorative panel can be easily realized at low cost.

Further, by increasing the cross-sectional shape of the pillar body 101, the thickness of the outer peripheral layer 99 can be reduced, so that the number of plies (the number of stacked sheets) of the prepreg 118 can be reduced and the mechanical strength can be reduced. The material cost and the number of steps can be reduced without lowering.

According to the above construction, the gap between the left and right window glasses 49a and 49b is filled with the intermediate member 102 made of a solid metal rod, and the pressing member 103 is fixed thereto by the mounting bolt 106b. Thus, the width of the pillar 98 can be made as small as possible, and a wide field of view can be obtained from the inside to the outside, so that the field of view of the crew member can be widely improved.

Further, the pillar body 101 is made of a composite material.
Although it is conceivable that the intermediate member 102 and the intermediate member 102 are integrally molded, this not only makes it difficult to process, but also makes it difficult to mount the holding member mounting bolt 106b, which increases the width of the pillar body 101 in terms of strength. Will have to. Therefore, the pillar body 1 made of composite material
The combination of 01 and the metallic intermediate member 102 is rational in that it is not necessary to increase the width of the pillar main body 101. If the width of the pillar body 101 is widened, the field of view of the crew member is narrowed when the outside is viewed from the inside as described above, but the field of view of the crew member is widened according to the above configuration. can do.

Further, the outer peripheral layer 99, and hence each prepreg 118, can be made to have significantly higher fatigue strength by using high elastic fibers such as carbon fiber and aramid fiber as a reinforcing material, and can be remarkably increased in fatigue strength when passing through a tunnel and bird collision. It is possible to solve the problem of structural fatigue due to repeated loading due to the above.

Further, the pressing member 103 is made of a composite material obtained by impregnating a fiber reinforced material containing the above-mentioned highly elastic fibers with a matrix made of a thermosetting synthetic resin. With such a holding member 103, the window glasses 49a and 49b are attached so as to be sandwiched between the window body 49a and the pillar body 101,
Since the holding member 103 is attached so as to be detachable from the outside by the bolt 106a, the window glass 49
The a and 49b can be easily attached and detached, and the window glasses 49a and 49b can be easily replaced.

Further, as described above, the window frame 43 and the outer wall 4
When 7 is made of a composite material, the pillar body 101 is made of the same composite material, so that the difference in the coefficient of thermal expansion is small, the mounting structure is simple, the manufacturing is easy, and the assembling work is also easy. You can A conventional metal pillar is made by welding a solid rod and a reinforcing plate, and has a high rigidity even if the outer shape is small. If an attempt is made to secure equivalent rigidity with a fiber-reinforced composite material that has the same external dimensions as such a metal pillar, even if a high-elasticity fiber-reinforced material such as carbon fiber is used, the structure will have a large wall thickness. Is not sufficiently rigid and difficult to manufacture, but by using the pillar body 101 made of the fiber reinforced composite material and the intermediate member 102 made of stainless steel in combination,
The required rigidity can be obtained, and the outer shape does not unnecessarily increase in size, and a wide field of view can be secured.

Further, since the above-mentioned pillar 98 has a high bending rigidity, it is prevented that a large deformation is caused by the pressure fluctuation when passing through the tunnel, and each window glass 49a, 49b.
This prevents the problem that the product comes off. Even if the deformation is not so large, it is possible to prevent the problem that the airtightness and the watertightness between the pillar 98 and each of the window glasses 49a and 49b are deteriorated.

FIG. 10 is a cross-sectional view showing the mounting structure of the pillar 98 to the window frame 43, and FIG. 11 is a section line XI of FIG.
It is sectional drawing seen from -XI. The above-mentioned pillar 98 is attached to the window frame 43. As mentioned in connection with FIG.
The core 46 of the window frame 43 of the sandwich structure, that is, a portion of the core 46a disposed near the window glass fitting hole 48, which is more rigid than the portion 46a of the core, on the extension line of the pillar body 101. A pair of reinforcing members 121a, 121b made of a composite material, which is a high material, is embedded and is connected to the reinforcing members 121a, 121b at right angles, and on a supporting surface 122 of the window frame 43 for supporting the pillar body 101. A partition wall 123 extending along is buried.

The reinforcing members 121a and 121b are arranged at the same intervals as the width of the pillars 98 in the direction in which the part 46a of the core extends, that is, in the direction perpendicular to the paper surface of FIG. If desired, three or more such reinforcing members 121a and 121b may be provided. Further, both longitudinal end portions of the pillar main body 101 are integrated by adhering corner reinforcing sheets 124a and 124b made of a composite material, and the longitudinal end portions of the pillar main body 101 are connected to the window frame 43.
The upper edge portion 96 and the lower edge portion 97 are integrally fixed to each other.

FIG. 12 is a view for explaining the transmission state of the bending load from the pillar body 101 to the outer reinforcing member 121a. When a bending moment M that tends to bend inward is generated in the pillar main body 101 when passing through a tunnel or due to an impact force due to a bird collision, the pillar main body 101 is integrally fixed to the window frame 43, so that the pillar main body 101 is fixed. The couples F1 and F2 are generated by the bending moment M in the region where both ends in the longitudinal direction are connected. The region where the couples F1 and F2 are generated is a region in which the reinforcing members 121a and 121b and the partition wall 123 are embedded in the window frame 43, and shear stress is generated in this region due to the couple. That is, the shear load transmitted from the pillar body 101 to the window frame 43 is utilized by utilizing the reinforcing members 121a and 121b and the partition wall 123.
21b and the partition 123 can be received in the area | region where it is embedded. As described above, the reinforcing members 121a, 121a are provided at the portion of the window frame 43 where the shear load is transmitted from the pillar body 101, that is, the portion of the window frame 43 on the extension line of the pillar body 101.
121b and the partition wall 123 are embedded, and the window frame 43
The load transmitted to the core 46, the inner layer 44, and the outer layer 45 is diffused and is dispersed and transmitted in the thickness direction and the extending direction of the window frame 43. The shearing load acting on the window frame 43 is transmitted to the pressing member 103, and the pressing force applied to the outside of the pressing member 103 is transmitted to the intermediate member 102 via the cap nut 105 and the bolt 106 to be loaded, and the moment M
Is resisted by the pillar body 101 and the intermediate member 102. Due to this bending moment M, the pillar body 101
Since the inner region is the tensile region, a thick region 118a is formed in which the vicinity of both ends of the plurality of prepregs 118 are stacked as shown in FIG. 9, and a large compressive strength resists the bending moment M. Configured to be able to.

FIG. 13 is a diagram for explaining a transmission state of a bending load from the pillar body 101 to the pressing member 103. When the bending moment M similar to that described above acts on the pillar body 101, the inside (right side in FIG. 13) becomes a compression region and the outside becomes a tension region. As described above, the pressing member 103 is fixed to the pulling region by the plurality of bolts 106, and the pulling force acts on each bolt 106. In order to resist such a pulling force, the base end portion 127 of the pressing member 103 is fixed to the window frame 43 by a plurality of bolts 128. Base part 1 which becomes this mounting part
Numeral 27 is wider than the pressing portion 129 connected to this, and the tensile force can be dispersed and transmitted to the window frame 43.

FIG. 14 is a view for explaining the transmission state of the bending load from the pillar body 101 to the corner reinforcing sheets 124a and 124b. When the shearing force H acts on the pillar main body 101 due to the pressure fluctuation when passing through the tunnel or the impact force due to the bird collision, a shearing stress is generated in the pillar main body 101. In order to reduce such shear stress, it is necessary to transmit and disperse the shearing force H from the pillar body 101 to the window frame 43, and for that purpose, the corner reinforcing sheets 124a and 124b are provided. With these corner portion reinforcing sheets 124a and 124b, the window frame 4 can be removed from both ends in the longitudinal direction of the pillar body 101.
3 securely transmits the shear load H to the pillar main body 101
It is possible to reduce the shear stress that occurs in the pillar body 101 and reduce the cross-sectional shape of the pillar body 101.

FIG. 15 is a flow chart showing the procedure for manufacturing the window frame 43 and the pillar 98, and FIG. 16 is a diagram showing the procedure for manufacturing the window frame 43 and the pillar 98. Work is started, jigs and tools are prepared in step a1, step a2
16 shows a plurality of prepregs 118 that form the outer layer 45 in FIG.
Laminated as shown in (1), the window glass fitting hole 48
A core stacking portion 131 having a triangular cross-section is placed on the portion where the core portion 46a in the vicinity is arranged, and the pillar 98 and the window frame 43 are connected to each other on the core stacking portion 131. Pillar joining sheet 132 is mounted.

At step a3, a plurality of prepregs 119 are formed on the part 46a of the core as shown in FIG. 16 (2).
Is wound and, as shown in FIG. 16C, stacked so that both ends overlap with the inner region. By the part of the prepreg 119, the split portion 87, the reinforcing member 121.
a, 121b and the partition wall 123 are formed. The remaining portion 46b of the core 46 is placed on the plurality of prepregs 118 for forming the outer layer 45 stacked on the jig in step a4 as shown in FIG. Part of the manufactured cores 46a is stacked, and further the pillar-bonding sheet 13 of the part that forms the window frame 43.
The pillar 101 is placed on the upper part 2 and the corner reinforcing sheet 124 (subscripts a and b are omitted when collectively referred to) is also placed.

Next, at step a6, as shown in FIG. 16 (5), a plurality of prepregs 13 forming the inner layer 44 are formed.
In addition to stacking 0, a pillar joining sheet 133 for joining pillars on the inside is piled up, holes are formed, the cap nut 61 is attached and finished, and autoclave molding is performed to complete the manufacturing operation.

Since the pillar 98 is attached to the window frame 43 in this manner, the force in the out-of-plane direction of each window glass 49a, 49b acts as a shear load from the pillar 98 via each corner portion reinforcing sheet 124 and the like. 43, but can be diffused to the core 46, the inner layer 44 and the outer layer 45 by the reinforcing members 121a and 121b and the partition wall 123 embedded therein, and the load on the pillar 98 and its mounting portion can be reduced. You can The moment load of the pillar 98 is directly transmitted to the inner layer 44 and the outer layer 45 on the inner surface side of the pillar via the corner reinforcing sheets 124, and is transmitted to the inner layer 44 and the outer layer 45 by the holding member 103 on the outer surface side of the pillar. It is natural as a transmission path of, is stably dispersed and absorbed, and can resist external force.

Further, although the load is concentrated on the end portion of the pressing member 103, a wide width can be taken at the base end portion of the pressing member 103, whereby a sufficient number of bolts 128 can be hit and the pillar 98 can be connected to the window frame 43 with great strength.

Since the force transmission between the pillar 98 and the window frame 43 is transmitted by in-plane stress such as shearing force and tensile force of the composite member, the corner portions made of the thin composite material as described above. Reinforcing sheets 124a, 124
b and the pillar-bonding sheet 130 can be bonded to each other without difficulty. In the case of connecting with a metal fitting as in the conventional case, since the bending moment and the shearing force are simultaneously transmitted by one fitting, the strength of the fitting increases, but in the present embodiment, the bending moment and the shearing force are increased. Since a path for individually transmitting each force component is formed, it can be transmitted by a lightweight and thin member, whereby the window glasses 49a and 49b and the pillar 98 interfere with a mounting member or the like. No trouble occurs.

Further, the pillar body 101 and each reinforcing member 121
a, 121b, partition wall 123, each corner portion reinforcing sheet 12
4a, 124b and the pillar joint sheet 132, etc.
Since it is formed of a composite material containing high elastic fibers, it has a high fatigue strength and can achieve sufficient strength against structural fatigue that cannot be prevented by a metal structure.

According to the present invention as set forth in claim 1, both ends of the pillar body are integrally fixed to the window frame, and a reinforcing member and a partition wall are provided at a portion of the window frame where the pillar body is continuous. It is provided over both the inner and outer layers. In this way, when a large load transmitted from the window glass is applied to the pillar body provided in the high-speed vehicle due to the impact force due to the bird collision and the pressure fluctuation when passing through the tunnel, a bending moment that tends to bend inward is generated in the pillar body, and A couple is generated in a portion where both ends of the pillar body in the frame are integrated and continuous. That is, when the load is transmitted from the pillar main body to the window frame, the reinforcing member and the partition wall are provided at the portion where the pillar main body is continuous, so that the load transmitted to the window frame is supported by the reinforcing member and the partition wall. This makes it possible to withstand with great strength the load acting on the window frame from the pillar body, and ensure the large load acting on the pillar body from the window glass due to the impact force due to bird collision and the pressure fluctuation when passing through the tunnel. It is possible to support the window glass with great strength by transmitting it to the window frame and resisting the load by this window frame. Since the composite material including the high elastic fiber has high fatigue strength, the problem of structural fatigue that cannot be prevented by the metal material does not occur in the window frame. As described above, the pillar frame can be supported and the window glass can be supported with great strength by the window frame of the high-speed vehicle made of the composite material and the foamed synthetic resin that does not cause structural fatigue.

According to the second aspect of the present invention, since the outer peripheral layer made of the composite material is formed on the core made of the hard foam synthetic resin, the pillar main body having higher fatigue strength and bending rigidity can be realized. it can.

According to the third aspect of the present invention, since the orientation directions of the reinforcing member and the partition wall are mainly set to ± 45 ° with respect to the extension line of the pillar body, the shearing force acting on the pillar body is formed. The load can be distributed and transmitted to the window frame, preventing the load from concentrating on the narrowest area, and distributing the load from the pillar body to the window frame requires high strength. It prevents the problem of becoming.

According to the fourth aspect of the present invention, since the strength of the mounting portion of the pillar body to the window frame is improved by the reinforcing sheet, the amount of deformation of the mounting portion can be made equal to that of the window frame. At the same time, structural fatigue is suppressed and damage is prevented.

According to the fifth aspect of the present invention, since the pressing member is detachably connected to the window frame by the screw member, a part of the load acting on the pressing member is directly connected to the window member through the screw member. The load transmitted to the frame and transmitted from the pressing member to the pillar body is reduced, and the cross-sectional shape of the pillar body can be reduced.

According to the present invention as set forth in claim 6, since the mounting portion of the pressing member is wide, and the mounting portion is detachably connected to the window frame by a plurality of screw members, the pressing member is the window. It is attached to the frame with great strength by the plurality of screw members. That is, when the above-mentioned bending moment is generated in the pillar body, the inside of the pillar body becomes the compression area and the outside of the pillar body becomes the tension area. By providing a pressing member on such a pulling region side, the pulling force can be resisted. The mounting portion of the pressing member is wide, and is fixed to the window frame with a plurality of bolts at the mounting portion. As a result, the tensile force can be dispersed and transmitted to the window frame, and the pressing member can be attached to the window frame with great strength. Therefore, the pillar body can be attached to the window frame with great strength.
