Description

  The present invention relates to a vehicle pillar structure in which at least an outer pillar on the vehicle outer side and an inner pillar on the vehicle inner side are joined to form a closed cross section, and a filling member is interposed in the closed cross section.

  Conventionally, a vehicle pillar structure shown in FIG. 9 is known (see, for example, Patent Document 1).

  The pillar P includes an outer pillar 1 positioned on the outer side of the vehicle, an inner pillar 2 positioned on the inner side of the vehicle, and a reinforcement 3 positioned between the outer pillar 1 and the inner pillar 2. A filler 4 made of a foamed resin material is interposed between the outer pillar 1 and the reinforcement 3.

  The outer pillar 1 is formed in a cross-sectional hat shape by a main body portion 1a having a U-shaped cross section and flange portions 1b projecting outward from both end portions of the main body portion 1a.

  The inner pillar 2 is also formed in a cross-sectional hat shape by a body portion 2a having a U-shaped cross section and flange portions 2b projecting outward from both end portions of the body portion 2a.

  Further, the reinforcement 3 is also formed in a cross-sectional hat shape by a main body portion 3a having a U-shaped cross section and flange portions 3b projecting outward from both ends of the main body portion 3a.

  Then, the flange portion 3b of the reinforcement 3 is disposed between the flange portion 1b of the outer pillar 1 and the flange portion 2b of the inner pillar 2, and is integrally welded and fixed by spot welding sandwiched from two directions of the outer pillar 1 side and the inner pillar 2 side.

JP 2002-173049 A

  By the way, in the above-described pillar structure, the flange portions 1b, 2b, 3b protruding outward from both end portions of the main body portions 1a, 2a, 3a are fixed by welding. Therefore, the flange parts 1b, 2b, 3b protrude outward from the closed cross section H, and the problem that the cross-sectional area of the pillar P cannot be made small has arisen.

  This also causes a problem that the angle of obstruction increases, the driver's field of view is narrowed, and the visibility is poor.

  Accordingly, an object of the present invention is to provide a vehicle pillar structure that can reduce the cross-sectional area of the pillar, reduce the obstruction angle, and improve the visibility.

  In order to solve the above problems, the present invention has at least an outer pillar positioned on the vehicle outer side and an inner pillar positioned on the vehicle inner side, and integrally joining the respective edges to form a closed cross section. In the vehicle pillar structure in which the filling member is interposed in the closed section, a plurality of convex portions to be joined to the outer pillar are formed at the edge of the inner pillar, and the convex portion and the outer pillar are joined to each other. The joined portion is formed along the peripheral surface of the closed cross section, and the filling member is formed in advance so as to be disposed in a state of providing a gap with the convex portion.

  According to the present invention configured as described above, the convex portion formed on the inner pillar is joined to the outer pillar, and the joint portion where the outer pillar and the convex portion of the inner pillar are joined is along the circumferential surface of the closed cross section. .

  As a result, the joint does not protrude outward from the closed cross section, and the cross-sectional area of the pillar can be reduced. And it becomes possible to reduce a disturbance angle, to expand a driver | operator's visual field range, and to improve visibility.

  Moreover, since the outer pillar is joined to the convex portion formed on the inner pillar, the outer pillar can be joined while being supported by the convex portion, and can be easily joined.

  Further, since the filling member is formed in advance so as to be disposed with a gap between the convex portions, the filling member is not affected by the heat generated when the outer pillar and the inner pillar are joined, The surface can be interposed in a smooth state.

  Therefore, the load input from the front surface of the vehicle can be smoothly transmitted by the filling member, and the reaction force from the passenger compartment side can be efficiently increased. Further, the closed cross section can be supported from the inside by the filling member, the pillar deformation is suppressed, and the bending rigidity can be improved.

  Next, a best mode for carrying out a vehicle pillar structure according to the present invention will be described with reference to the drawings.

  A vehicle S shown in FIG. 1 includes a front pillar 12 provided between a front portion of a side roof rail 10 extending in the vehicle front-rear direction and a front portion of a side sill 11 extending in the vehicle front-rear direction, and extending substantially in the vertical direction. I have. Here, R is a passenger compartment, and the front pillar 12 forms a front edge portion of an opening 13 provided on the side of the passenger compartment R.

  1, 2, and 3 (a), the arrow OUT indicates the outside of the left front pillar 12 when viewed from the front of the vehicle S, and the arrow IN indicates the left front when viewed from the front of the vehicle S. The inside of the pillar 12 is shown.

  As shown in FIG. 1, the front pillar 12 includes an upper pillar 14 positioned above and a lower pillar 15 positioned below the upper pillar 14.

  As shown in FIG. 2, the upper pillar 14 is disposed between the body side outer (outer pillar) 20 positioned on the vehicle outer side, the inner pillar 30 positioned on the vehicle inner side, and the body side outer 20 and the inner pillar 30. The reinforce 40 is provided.

  The body side outer 20 extends to the side sill 11 and is integrated with the outer panel of the lower pillar 15.

  Further, an edge wall 21 is formed on one edge in the short side direction of the body side outer 20. The end edge wall 21 is formed by bending the side wall 22 toward the vehicle inner side (see FIG. 3A). Note that the edge wall 21 faces the upper side of the vehicle, and the other short side edge facing the lower side of the vehicle is omitted.

  Moreover, the inner pillar 30 is extended so that the dash side vicinity part 17 mentioned later may be covered (refer FIG. 2).

  An edge wall 31 is formed at one short side edge of the inner pillar 30. The end edge wall 31 is formed by bending the side wall 32 toward the vehicle outer side (see FIG. 3A). The edge wall 31 faces the upper side of the vehicle, and the other short-side edge facing the lower side of the vehicle is omitted.

  As shown in FIG. 3A, the end edge wall 31 is formed with a plurality of convex portions 33 that fit into a notch portion 44 described later and project toward the upper side of the vehicle S. Has been.

  Each convex portion 33 is formed at the end portion 31 a of the end edge wall 31, and protrudes by almost the same height as the thickness of the reinforcement 40. And it has a rectangular shape substantially along the inner peripheral edge 44 a of the notch 44.

  Further, the reinforcement 40 extends to the middle part of the lower pillar 15.

  An edge wall 41 is formed at one edge in the short direction of the reinforcement 40. The end edge wall 41 is formed by bending the side wall 42 toward the vehicle inner side (see FIG. 3A). The edge wall 41 faces the upper side of the vehicle, and the other short side edge facing the lower side of the vehicle is omitted.

  And in this edge wall 41, as shown to Fig.3 (a), the some joining piece 43 joined to the edge wall 21 of the body side outer 20 and this several joining piece 43 are located alternately. A plurality of notches 44 are formed.

  The joining piece 43 and the notch 44 are formed at the end 41 a of the end wall 41, have a rectangular shape extending along the longitudinal direction of the reinforcement 40, and are substantially the same size.

  And each end edge wall 21, 31, and 41 is joined integrally, and the closed cross-section H which shows the one part in FIG. 4 is formed. At this time, the end wall 21 of the body side outer 20, the end wall 41 of the reinforcement 40, and the end wall 31 of the inner pillar 30 are overlapped with each other in the opposite directions.

  Here, a portion where the end wall 21, 31, 41 is joined is referred to as a joint 16. Since the end edge walls 21 and 41 and the end edge wall 31 are opposite to each other, the joint portion 16 is formed along the peripheral surface of the closed section H. That is, the joint portion 16 does not protrude outward from the closed section H and is integrated with the peripheral surface of the closed section H.

  In addition, as shown in FIG. 4, the body side outer 20 and the side walls 22 and 42 of the reinforcement 40 are piled up in a state of being in close contact in the vicinity of the joint portion 16. However, it may be appropriately bent so that the gap gradually opens.

  Further, a filling member 50 shown in FIG. 2 is interposed between the inner pillar 30 and the reinforcement 40 in the closed section H.

  Here, the filling member 50 is formed in advance by a light alloy such as an aluminum alloy having a honeycomb structure so as to have substantially the same shape as the closed section H. Further, the filling member 50 is interposed so as to be in close contact with the inside of the joint portion 16, but is formed so as to open a gap K between the convex portion 33 formed on the inner pillar 30. (See FIG. 4B).

  Here, the “honeycomb structure” is a honeycomb-like structure in which a large number of hexagonal holes are opened, and a detailed description thereof is omitted here.

  Further, as shown in FIG. 2, the filling member 50 is filled up to the dash side vicinity 17 in which the upper pillar 14 and the lower pillar 15 are integrated.

  The “dash side vicinity” is a portion including the side portion of the dash panel D separating the vehicle compartment R and the engine room E and the periphery thereof (see FIG. 1).

  Next, the operation of the vehicle pillar structure of the present invention will be described.

  To assemble the front pillar 12, first, as shown in FIG. 3B, the body side outer 20 and the reinforcement 40 are joined by welding.

  At this time, the inner surface of the edge wall 21 of the body side outer 20 and the outer surface of the edge wall 41 of the reinforcement 40 are overlapped. That is, the edge wall 41 of the reinforcement 40 is covered with the edge wall 21 of the body side outer 20. Then, spot welding is performed so as to sandwich the body side outer 20 side and the reinforcement 40 side.

  The spot welding is a method in which members to be welded are overlapped, sandwiched between electrodes, energized and pressurized, and pressed in a dot shape.

  Here, the spot welding is indicated by SY in FIG. 3 (b), and the joining piece 43 of the reinforcement 40 and the body side outer 20 are opposed to each other.

  Here, spot welding is performed twice on one joining piece 43 in a state of being aligned in the longitudinal direction, but spot welding may be performed once on one joining piece 43. Further, the other short direction edge (not shown) is also joined by welding.

  As described above, when the body side outer 20 and the reinforcement 40 are joined, the previously formed filling member 50 is disposed on the inner side of the inner pillar 30.

  And as shown in FIG.3 (c), the inner pillar 30 and the body side outer 20 are joined. In FIG. 3C, the filling member 50 is omitted.

  At this time, the inner surface of the edge wall 41 of the reinforcement 40 and the outer surface of the edge wall 31 of the inner pillar 30 are overlapped. That is, at least a part of the end wall 31 of the inner pillar 30 is covered with the end wall 41 of the reinforcement 40.

  At this time, positioning is performed so that the convex portion 33 formed on the inner pillar 30 is fitted in the notch portion 44 formed on the reinforcement 40.

  And if the convex part 33 fits in the notch part 44 and the edge wall 21 of the body side outer 20 contacts this convex part 33, laser welding will be performed from one direction on the body side outer 20 side.

  This laser welding is a method of joining by irradiating a member to be welded with laser light in a focused state and locally melting and solidifying the member.

  Here, the location where laser welding is performed is indicated by LY in FIG. 3C, and is a location where the convex portion 33 of the inner pillar 30 and the body side outer 20 face each other. Further, the other short direction edge (not shown) is also joined by welding.

  On the other hand, the filling member 50 is formed in advance before joining the body side outer 20 and the inner pillar 30 and is disposed on the inner side of the inner pillar 30, so that the filling member 50 is joined to the inner side of the body side outer 20. It is interposed between the existing reinforcement 40 and the inner pillar 30.

  As described above, the closed cross section H is formed by the body side outer 20, the inner pillar 30, and the reinforcement 40, and the filling member 50 is disposed in the closed cross section H, and the front pillar 12 is assembled.

  At this time, the filling member 50 is molded so as to have substantially the same shape as the closed cross section H, and is in close contact with the inside of the joint portion 16, but between the convex portion 33 formed on the inner pillar 30. Is formed so that the gap K is opened (see FIG. 4B).

  Therefore, the filling member 50 is not affected by the welding heat generated when the body side outer 20 and the inner pillar 30 are joined by laser welding. Thereby, it becomes possible to interpose the surface of the filling member 50 in a smooth state.

  And the load input from the vehicle front surface by this filling member 50 can be transmitted smoothly, and the reaction force from the compartment R side can be increased efficiently. Moreover, the closed cross section H can be supported from the inside by the filling member 50, and the deformation of the front pillar 12 is suppressed, so that the bending rigidity can be improved.

  Further, as shown in FIG. 2, the filling member 50 is formed so as to be filled up to the dash side vicinity portion 17.

  Therefore, the filling member 50 supports the joint portion between the upper pillar 14 and the lower pillar 15 to improve the joint rigidity, thereby contributing to the rigidity of the vehicle body.

  Furthermore, since the filling member 50 is formed of a light alloy such as an aluminum alloy, the bending rigidity of the front pillar 12 is about 2.5 compared with the case where a resin filling member such as urethane foam is interposed. It can be improved by about 3 to 3 times.

  Even when compared with a front pillar formed of a metal such as iron, it is possible to reduce the weight and improve the rigidity.

  Therefore, sufficient rigidity can be ensured even if the size of the closed section H of the front pillar 12 is reduced.

  In addition, the joint piece 43 formed in the reinforcement 40 is joined to the body side outer 20, and the convex portion 33 formed in the inner pillar 30 that fits in the notches 44 positioned alternately with the joint piece 43. Are joined to the body side outer 20, the joint portion 16 that joins the body side outer 20, the reinforcement 40, and the inner pillar 30 follows the peripheral surface of the closed section H.

  Accordingly, the joint portion 16 does not protrude outward from the closed cross section H, and the cross sectional area of the front pillar 12 can be reduced. And it becomes possible to reduce the obstruction angle from a driver | operator and to expand a driver | operator's visual field range and to improve visibility.

  FIG. 5 shows the ratio of the obstruction angle of the front pillar 12 of the present invention when the obstruction angle of the conventional front pillar is 100%.

  According to this, it can be seen that the obstruction angle of the front pillar 12 of the present invention is about 82% compared with the conventional front pillar, and can be reduced by about 28%.

  Further, the convex portion 33 formed on the inner pillar 30 is formed by bending the end wall 31 of the inner pillar 30 toward the outside of the closed section H.

  Therefore, the rigidity around the convex portion 33 is increased, and when the body side outer 20 and the convex portion 33 are joined, the surface on the vehicle inner side of the body side outer 20 is supported by the convex portion 33. it can.

  Thereby, laser joining can be performed in a stable state, and the body side outer 20 and the inner pillar 30 can be easily joined without being displaced.

  Moreover, since this convex-shaped part 33 fits in the notch part 44 of the reinforcement 40, positioning can be performed easily.

  As described above, the vehicle pillar structure according to the present invention has at least the body side outer 20 that is the outer pillar positioned on the vehicle outer side and the inner pillar 30 positioned on the vehicle inner side. Are integrally joined to form a closed cross section H, and a filling member 50 is interposed in the closed cross section H, and the end wall 31 of the inner pillar 30 has a plurality of convex shapes joined to the body side outer 20. Forming the portion 33, the joint portion 16 where the convex portion 33 and the body side outer 20 are joined is along the peripheral surface of the closed cross-section H, and a gap is provided between the filling member 50 and the convex portion 44. It is formed in advance so as to be disposed in the state.

  Therefore, the joint 16 does not protrude outward from the closed section H, and the cross-sectional area of the front pillar 12 can be reduced. And it becomes possible to reduce a disturbance angle, to expand a driver | operator's visual field range, and to improve visibility.

  Further, the filling member 50 disposed with a gap between the convex portion 33 is not affected by heat generated when the body side outer 20 and the inner pillar 30 are joined, and the surface of the filling member 50 is smooth. It can be interposed in the closed cross-section H while being held at the same position.

  Thereby, the load input from the front surface of the vehicle can be smoothly transmitted by the filling member 50, and the reaction force from the passenger compartment R side can be efficiently increased. In addition, the closed section H can be supported from the inside by the filling member 50, and the deformation of the front pillar 12 due to the load input is suppressed, and the bending rigidity can be improved.

  In the pillar structure of the vehicle of the present invention, the reinforcement 40 is disposed between the body side outer 20 and the inner pillar 30, and the edge wall 21 of the body side outer 20 is provided on the edge wall 41 of the reinforcement 40. A plurality of joining pieces 43 to be joined to each other, and a plurality of cutout portions 44 that are alternately positioned with the plurality of joining pieces 43, and the convex portions 33 are fitted into the plurality of cutout portions 44, respectively. The filling member 50 is disposed between the reinforcement 40 and the inner pillar 30.

  In this way, the joining piece 43 formed on the reinforcement 40 is joined to the body side outer 20, and the convex portion 33 of the inner pillar 30 is fitted to the notch 44 formed on the reinforcement 40. Even if the rigidity of the front pillar 12 is improved, the joint 16 does not protrude outward from the closed section H.

  As a result, the cross-sectional area of the front pillar 12 can be reduced, the obstruction angle can be reduced, the driver's visual field range can be expanded, and the visibility can be improved.

  And even if the cross-sectional area of the front pillar 12 is reduced, sufficient rigidity can be ensured.

  Although one embodiment according to the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to the above-described embodiment. Design changes and the like within the scope not departing from the gist of the present invention are included in the present invention.

  For example, as shown in FIG. 6, the joint portion 16 is covered with a windshield 51 disposed on the vehicle outer side with respect to the body side outer 20, and the edge portion 51 a of the windshield 51 is interposed between the body side outer 20 and the body side outer 20. The molding member 52 may be covered by the arranged molding member 52.

  Thereby, it is possible to prevent intrusion of rainwater or the like from the joint portion 16 and to suppress generation of rust and the like.

  In the above-described embodiment, the filling member 50 is formed of a light alloy having a honeycomb structure. However, the filling member 50 may be formed of an aggregate of hollow iron balls in which a large number of hollow iron balls are integrated with an adhesive. Good.

  Even in this case, since the filling member 50 is not affected by the welding heat due to the convex portion 33, it is possible to prevent deterioration of the adhesive that integrates many hollow iron balls and to deform the filling member 50. Disappear.

  Therefore, the load input from the front of the vehicle can be transmitted smoothly, and the reaction force from the passenger compartment R side can be increased efficiently.

  And in the above-mentioned embodiment, although the body side outer 20 and the inner pillar 30 are joined by laser welding, as shown to Fig.7 (a)-(d), you may join by various methods. .

  In FIG. 7A, the end 21a of the edge wall 21 of the body side outer 20 and the intermediate portion of the convex portion 33 are integrally welded and fixed. In this case, the welding is fixed by MIG (metal inert gas welding) welding or TIG (tungsten inert gas welding) welding. Here, B in the figure is a weld bead.

  MIG welding is a kind of inert gas arc welding in which an arc and a weld are shielded with an inert gas and welding is performed, and is a melting electrode type using a welding wire as an electrode. TIG welding is MIG welding. Similarly, it is a kind of inert gas arc welding, which is a non-melting electrode type using a tungsten electrode.

  Moreover, the intermediate part of the convex part 33 is a part located in the side wall 32 side rather than the edge part 31a of this convex part 33, and is a transversal center part.

  According to this, it becomes possible to join the body side outer 20 and the inner pillar 30 easily.

  In FIG.7 (b), the edge wall 21 and the convex-shaped part 33 of the body side outer 20 are weld-joined by MIG-YAG (Yttrium Aluminum Garnet) hybrid welding. Here, B in the figure is a weld bead.

  The MIG-YAG hybrid welding is a combination of laser welding using light energy and arc welding using electric energy.

  According to this, the weld bead B can be made small and appearance can be improved.

  In FIG.7 (c), the insertion holes 53a and 53b are provided in the mutually opposing position of the edge wall 21 and the convex part 33 of the body side outer 20, and each insertion hole 53a and 53b can be operated from one direction. A fixable blind rivet BR is inserted. And the body side outer 20 and the inner pillar 30 are joined by this blind rivet BR.

  Further, a recess 50a is formed in advance in a portion of the filling member 50 facing the blind rivet BR.

  According to this, the welding technique is not necessary, and the body side outer 20 and the inner pillar 30 can be joined very easily.

  In FIG.7 (d), the edge part 21a of the edge wall 21 of the body side outer 20 and the edge part 31a of the convex-shaped part 33 are weld-fixed by friction stir welding (FSW; Frictin Stir Welding). Has been. Here, Y in the figure is a welding region.

  The friction stir welding is a method in which a welding tool is pushed into a butt portion of members to be welded while rotating, and the members softened by friction heat are stirred and joined.

  According to this, since the body side outer 20 and the convex part 33 do not overlap, it becomes possible to achieve weight reduction.

  Further, as shown in FIG. 8, the end 21 a of the end wall 21 of the body side outer 20, the joining piece 43 of the reinforcement 40, and the notch 44 may be formed in a smoothly continuous wave shape. Good.

  At this time, a first arc portion 34 substantially along the end portion 21a of the end edge wall 21 of the body side outer 20 and a first arc portion 34 substantially along the inner periphery 44a of the notch portion 44 are provided at the peripheral portion of the convex portion 33 of the inner pillar 30. Two arc portions 35 are formed.

  Here, the end portion 21a of the edge wall 21 of the body side outer 20 has a portion (point A in FIG. 8A) located on the outermost side facing the tip of the joining piece 43 and is located on the innermost side of the vehicle. The portion (point B in FIG. 8 (a)) faces the portion of the notch 44 that is located on the outermost side of the vehicle.

  Thereby, the edge wall 41 of the reinforcement 40 is completely covered with the edge wall 21 of the body side outer 20 (refer FIG.8 (b)).

  Moreover, the 1st circular arc part 34 and the 2nd circular arc part 35 which were formed in the peripheral part of the convex-shaped part 33 are continuing, and the convex-shaped part 33 is exhibiting elliptical shape.

  In such a front pillar 12, as shown in FIG. 8B, the body side outer 20 end edge wall 21 and the joining piece 43 of the reinforcement 40 are first joined by spot welding.

  And as shown in FIG.8 (c), the convex-shaped part 33 of the inner pillar 30 is fitted in the notch part 44 of the reinforcement 40, and the body side outer 20 and the inner pillar 30 are joined by laser welding.

  In this way, the end 21a of the end wall 21 of the body side outer 20, the joining piece 43 of the reinforcement 40, and the notch 44 are formed in a wave shape, and the first and Since the two arc portions 34 and 35 are formed, the end edge wall 21 of the body side outer 20 and the end edge wall 41 of the reinforcement 40 can each be formed in a smoothly continuous curved shape.

  For this reason, stress concentration is less likely to occur, and the change in bending rigidity is reduced. Further, the breakage base point of the front pillar 12 disappears when a load is input, and the rigidity of the front pillar 12 can be further improved.

  In the above-described embodiment, the front pillar 12 has been described. However, the present invention is not limited to this, and a center pillar or a rear pillar may be used.

  Even in this case, the cross-sectional area of the pillar can be reduced, the obstruction angle can be reduced, and the driver's visibility can be improved.
