Description
This application claims priority to japanese patent application No.2008-111303, filed on 22.4.2008, the entire contents of which are incorporated herein by reference.
Technical Field
The present invention relates to a vehicle center pillar structure including an outer panel, an inner panel, and a reinforcement member.
Background
In the related art center pillar structure provided in a vehicle, each of the reinforcement member, the outer panel, and the inner panel is formed to have a hat-shaped cross section including a front side flange formed on the vehicle front side, a rear side flange formed on the vehicle rear side, and a bulging portion formed therebetween. The front side flange of the reinforcing member is inserted between the front side flange of the outer panel and the front side flange of the inner panel so that the three front side flanges are integrally welded to be connected to each other. The rear side flange of the reinforcing member is inserted between the rear side flange of the outer panel and the rear side flange of the inner panel so that the three rear side flanges are integrally welded to be connected to each other (see patent document 1).
Patent document 1: japanese patent publication No. 2002-347655A.
According to the structure of the related art as described above, when the vehicle center pillar structure is formed to have a closed cross section as shown in fig. 3 of patent document 1, the rigidity and strength of the vehicle center pillar structure can be enhanced. However, the front side flange as the inner panel front edge is straightened toward the vehicle front side to the flange of the reinforcement member, and the rear side flange as the inner panel rear edge is straightened toward the vehicle rear side to the rear side flange of the reinforcement member. For this reason, the width (length) of the inner panel in the vehicle length direction becomes large, thereby increasing the size of the inner panel and the weight of the vehicle.
Disclosure of Invention
It is therefore an object of at least one embodiment of the present invention to provide a vehicle center pillar structure capable of reducing its weight while ensuring its rigidity and strength. Also, another object of at least one embodiment of the invention is to provide a vehicle center pillar structure that can easily control the deformation mode of the center pillar due to an impact load applied from the side of the vehicle.
According to an aspect of at least one embodiment of the present invention, there is provided a vehicle center pillar structure including: an outer plate; an inner plate; and a first reinforcement member formed to have a hat-shaped cross section including a bulging portion, a front flange provided on a front side of the bulging portion in a longitudinal direction of the vehicle, and a rear flange provided on a rear side of the bulging portion in the longitudinal direction of the vehicle, wherein the front flange of the first reinforcement member is welded to a front edge of the inner panel to form a first joint portion, the rear flange of the first reinforcement member is welded to a rear edge of the inner panel to form a second joint portion, the front flange of the first reinforcement member is provided with a front extension portion extending from the first joint portion between the front flange of the first reinforcement member and the front edge of the inner panel toward the front side of the vehicle, the rear flange of the first reinforcement member is provided with a rear extension portion extending from the second joint portion between the rear flange of the first reinforcement member and the rear edge of the inner panel toward the rear side of the vehicle, the front extension is welded to the outer panel to form a third connecting portion and the rear extension is welded to the outer panel to form a fourth connecting portion. The first connecting portion may include a plurality of first welded portions that are arranged at intervals in a vertical direction of the vehicle, the second connecting portion may include a plurality of second welded portions that are arranged at intervals in the vertical direction of the vehicle, the third connecting portion between the front extension portion and the outer panel may include a plurality of third welded portions that are arranged at intervals in the vertical direction of the vehicle, the fourth connecting portion between the rear extension portion and the outer panel may include a plurality of fourth welded portions that are arranged at intervals in the vertical direction of the vehicle, the first welded portions may be offset from the third welded portions in the vertical direction of the vehicle, and the second welded portions may be offset from the fourth welded portions in the vertical direction of the vehicle.
With the above configuration, the first reinforcement member has a hat-shaped cross section including the front flange, the rear flange, and the bulging portion, and the front edge and the rear edge of the inner panel are welded to the front flange and the rear flange of the first reinforcement member, respectively. Therefore, a closed section can be formed by the first reinforcement member and the inner panel, and the bulging portion of the first reinforcement member can be restricted from being separated from each other by the inner panel at both side walls (the side wall on the vehicle front side and the side wall on the vehicle rear side) of its hat-shaped section. As a result, the rigidity and strength of the center pillar portion including the reinforcement member and the inner panel can be sufficiently improved.
Further, the front flange of the first reinforcing member is provided with a front extension portion extending from the front side of the first connecting portion, and the front extension portion is welded to the outer panel. The rear flange of the first reinforcing member is provided with a rear extension portion extending from the second connecting portion toward the rear side, and the rear extension portion is welded to the outer panel. Therefore, the front end and the rear end of the first reinforcement member serve as inner plates. Generally, the reinforcing member such as the first reinforcing member has high strength. Therefore, even if the inner plates are not used in the third and fourth connecting portions, the rigidity and strength of the third connecting portion and the fourth connecting portion can be ensured. Further, the width (length) of the inner panel in the longitudinal direction of the vehicle can be reduced, and the size of the inner panel can be reduced, as compared with a structure in which the front edge and the rear edge of the inner panel are welded to the front flange and the rear flange of the outer panel, respectively. As a result, the weight of the vehicle can be reduced.
For example, if the first welded portion constituting the first connecting portion between the front flange of the first reinforcement member and the front edge of the inner panel and the third welded portion constituting the third connecting portion between the front extension portion of the first reinforcement member and the outer panel are arranged at the same position in the vertical direction of the vehicle, the first welded portion has to be arranged at a position away from the third welded portion toward the vehicle rear side so as not to interfere with the third welded portion. Also, if the second welded portion and the fourth welded portion are arranged at the same position in the vertical direction of the vehicle, the second welded portion has to be arranged at a position away from the fourth welded portion toward the front side of the vehicle. Therefore, the rear end of the front flange of the first reinforcing member provided with the first welded portion extends further toward the rear side, and the front end of the rear flange of the first reinforcing member provided with the second welded portion extends further toward the front side. As a result, since the gap between both side walls of the bulging portion of the first reinforcing member becomes narrow, the size of the closed cross section becomes small.
In contrast, with the above configuration, even when each gap between the first welded portion and the third welded portion is short in the longitudinal direction of the vehicle, and each gap between the second welded portion and the fourth welded portion is short in the longitudinal direction of the vehicle, interference between the first welded portion and the third welded portion can be prevented, and interference between the second welded portion and the fourth welded portion can be prevented. Therefore, the area of the welding position can be ensured. Also, the first welded part may be disposed on a front side of the third welded part, and the second welded part may be disposed on a rear side of the fourth welded part. Also, the gap between both side walls of the bulging portion of the first reinforcing member can be increased, and the size of the closed cross-section can be increased. As a result, the rigidity and strength of the intermediate pillar can be improved.
The bulging portion of the first reinforcement member may bulge toward the vehicle outside in the width direction of the vehicle with respect to the front flange and the rear flange of the first reinforcement member, the inner panel may be formed to have a hat-shaped cross section including the bulging portion, the front flange disposed on a front side of the bulging portion in the length direction of the vehicle, and the rear flange disposed on a rear side of the bulging portion in the length direction of the vehicle, the front flange of the inner panel may include a front edge of the inner panel, the rear flange of the inner panel may include a rear edge of the inner panel, the bulging portion of the inner panel may bulge toward the vehicle interior in the width direction of the vehicle with respect to the front flange and the rear flange of the inner panel, and a bulging amount of the bulging portion of the inner panel may be smaller than a bulging amount of the bulging portion of the first reinforcement member.
Since both the first reinforcement member and the inner panel are formed to have hat-shaped sections, a large closed section can be obtained, and the rigidity of the intermediate pillar structure can be improved. Therefore, since the rigidity of the vehicle body is improved, the driving safety can be improved.
Further, since the bulging amount of the bulging portion of the inner panel is smaller than that of the bulging portion of the first reinforcement member, it is possible to easily suppress deformation of the bulging portion of the inner panel even if the inner panel is made thinner than the first reinforcement member. Therefore, the inner panel can restrict the both side walls of the bulging portion of the first reinforcing member from being separated from each other.
Further, since the closed section can be formed over a wide range by the first reinforcing member which generally has high strength, the rigidity and strength of the intermediate pillar structure can be improved by the first reinforcing member.
A portion of the front edge of the inner panel in one of the first welded portions may protrude toward the front side of the vehicle relative to the other portion of the front edge of the inner panel, and a portion of the rear edge of the inner panel in one of the second welded portions may protrude toward the rear side of the vehicle relative to the other portion of the rear edge of the inner panel.
Therefore, the size (area) of the front flange of the inner panel except for the welding position can be minimized. Further, the size (area) of the inner panel at the rear flange other than the welding position can be minimized. As a result, the size of the inner panel can be reduced, and thus the weight of the vehicle can be reduced.
A part of a front edge of the first reinforcing member in one of the third welded portions may be projected toward the front side of the vehicle with respect to the other part of the front edge of the first reinforcing member, and a part of a rear edge of the first reinforcing member in one of the fourth welded portions may be projected toward the rear side of the vehicle with respect to the other part of the rear edge of the first reinforcing member.
Therefore, the size (area) of the front flange of the first reinforcement member other than the welding position can be minimized. Further, the size (area) of the rear flange of the first reinforcement member other than the welding position can be minimized. As a result, it is possible to reduce the size of the first reinforcement member, and thus reduce the weight of the vehicle.
The lower end of the first reinforcement member may extend toward the side seal to be connected thereto, the lower end of the inner panel may be disposed above the upper end of the side seal inner panel to form a space for accommodating a retractor (retractor) between the lower end of the inner panel and the upper end of the side seal inner panel, and an attachment portion provided at the lower end of the inner panel may attach an attachment portion provided in the retractor.
Therefore, the base end (lower end) of the center pillar has a cross section that is open toward the vehicle interior side in the width direction of the vehicle, rather than a closed cross section formed by the reinforcement member and the inner panel. For this reason, in the lower end of the reinforcement member, it is difficult to restrict the both side walls (the side wall on the vehicle front side and the side wall on the vehicle rear side) of the bulging portion of the hat-shaped cross section of the first reinforcement member from being separated from each other by the inner panel. Therefore, the rigidity and strength of the lower end of the middle pillar are weaker than those of the other portions of the middle pillar, and the lower end of the middle pillar is likely to be deformed toward the interior of the vehicle when a side collision occurs. As a result, the deformation mode of the intermediate strut can be optimized. Also, it is possible to shorten the length of the inner panel (in the vertical direction of the vehicle) and thus reduce the weight of the vehicle, as compared with a structure in which the inner panel extends to the upper end of the side seal.
The first reinforcement member may be fixed with a second reinforcement member that is disposed outside the retractor in the width direction of the vehicle to reinforce a lower end of the first reinforcement member, and a lower end of the second reinforcement member may be located below a lower end of the inner panel. Therefore, the rigidity and strength of the lower end of the center pillar below the inner panel can be easily controlled by the second reinforcement member. As a result, the deformation mode of the center pillar at the time of a side collision of the vehicle can be further optimized.
The second reinforcing member may be formed to have a hat-shaped cross section including a bulging portion, a front flange provided on a front side of the bulging portion in a longitudinal direction of the vehicle, and a rear flange provided on a rear side of the bulging portion in the longitudinal direction of the vehicle, a length of the second reinforcing member in the longitudinal direction toward the second reinforcing member may become larger, the bulging portion of the second reinforcing member may overlap on the bulging portion of the first reinforcing member from a vehicle inner side in a width direction of the vehicle and be welded to the bulging portion of the first reinforcing member, and the front flange and the rear flange of the second reinforcing member may overlap on the front flange and the rear flange of the first reinforcing member, respectively, and be welded to the front flange and the rear flange of the first reinforcing member. With the above configuration, since the rigidity and strength of the second reinforcing member can be improved, and the size of the second reinforcing member can be reduced, the weight of the vehicle can be reduced.
The seat bracket may be fixed to the side seal inner panel and offset from a center axis of a lower end of the outer panel in a longitudinal direction of the vehicle toward a front side of the vehicle, between the vehicle body and a rear end of a seat rail that slidably supports a vehicle seat in the longitudinal direction of the vehicle to connect the rear end of the seat rail to the vehicle body. With the above configuration, since the center pillar can be disposed on the rear side of the vehicle seat, it is possible to prevent interference between the seat and the center pillar when a side collision of the vehicle occurs, an impact load is generated, and the latter is deformed. Further, the intermediate pillar can be reliably deformed in the space on the seat rear side.

Fig. 1 to 5 show a vehicle (automobile) center pillar structure including an outer panel 1, an inner panel (center pillar inner panel) 2, a first reinforcement member 3, a second reinforcement member 4, and a center pillar garnish 5. The center pillar has a configuration in which an outer panel 1, an inner panel 2, a first reinforcement member 3, a second reinforcement member 4, and a center pillar garnish 5 extend in an obliquely vertical direction such that an upper end is located slightly closer to the vehicle rear side than a lower end. The middle pillar trim 5 includes a lower trim 5A and an upper trim 5B that are separated from each other. As shown in fig. 2, the upper end side engagement portion R1 of the lower garnish 5A is engaged with the lower end side engagement portion R2 of the upper garnish 5B. In fig. 1, reference numeral 6 denotes a front door opening, and reference numeral 7 denotes a rear door opening. Next, the structures of the outer panel 1, the inner panel 2, the first reinforcing member 3, and the second reinforcing member 4 will be described simply, and then the structures and the connecting structures will be described in detail.
[ Structure of outer panel 1 ]
The outer panel 1 is a panel member forming a vehicle side trim surface, where an upper portion forms a roof side rail and a lower portion forms a vehicle outer panel in a side seal, and a front door opening 6 and a rear door opening 7 are provided therein. Further, the outer panel 1 is a component located at the vehicle outer side W2 (the left and right outer sides of the vehicle body) of the center pillar in the width direction of the vehicle. As shown in fig. 2, the outer panel 1 is formed in a longitudinal section of a smooth convex arc shape toward the vehicle outer side W2 of the center pillar. As shown in fig. 5, the outer panel 1 is formed to have a hat-shaped cross section, and includes: a front side flange 1F1 extending in the longitudinal direction of the vehicle from the vehicle front side Fr; a rear side flange 1F2 extending from the vehicle rear side in the longitudinal direction of the vehicle; and a swollen portion (swellen portion)1B formed therebetween. The bulging portion 1B bulges toward the vehicle outer side W2 with respect to the front side flange 1F1 and the rear side flange 1F 2. Further, as shown in fig. 1 and 6, the width of the upper end of the raised portion 1B becomes narrower toward the upper side Z1, and the width of the lower end thereof becomes wider toward the lower side (the width refers to the length in the vehicle length direction, and the same applies hereinafter).
[ Structure of the first reinforcing member 3 ]
The first reinforcement member 3 is a member that reinforces the intermediate pillar, and is arranged within the closed section of the intermediate pillar. In more detail, the first reinforcing member 3 is located on the vehicle interior side W1 of the outer panel 1 in the width direction of the vehicle. As shown in fig. 2, the first reinforcing member 3 is formed along the outer panel 1 so as to have a smoothly convex circular arc-shaped longitudinal section toward the vehicle outer side W2. The upper end of the first reinforcing member 3 is formed in a shape extending in the longitudinal direction of the vehicle, the shape extending in the longitudinal direction of the vehicle being partially located within the closed cross section of the roof side rail formed in the vicinity of the upper end of the outer panel 1 to be connected to the roof side rail, and the upper end of the first reinforcing member 3 is fixedly weld-connected to the roof side inner reinforcing member of the reinforcing member arranged within the closed cross section of the roof side rail in the longitudinal direction of the vehicle. Further, as shown in fig. 3 to 5, the first reinforcing member 3 is formed to have a hat-shaped cross section including: a front side flange 3F1 extending in the longitudinal direction of the vehicle from the vehicle front side Fr; a rear side flange 3F2 extending from the vehicle rear side in the longitudinal direction of the vehicle; and a raised portion 3B formed therebetween. The bulging portion 3B bulges toward the vehicle outer side W2 with respect to the front side flange 3F1 and the rear side flange 3F 2. The width of the upper end of the bulged portion 3B of the first reinforcing member 3 is narrowed toward the upper side Z1, and the width of the lower end thereof is widened toward the lower side, thereby allowing the first reinforcing member 3 to have a shape corresponding to the shape of the outer panel 1.
The bulging portion 3B is formed of a plate member forming the first reinforcing member 3, and is bent (stretched) by press working. The raised portion 3B includes: a side wall 3S1, the side wall 3S1 being curved toward the vehicle outside from the rear end of the front flange 3F1 so as to form a part at the vehicle front side; a side wall 3S2, the side wall 3S2 being curved from the front end of the rear side flange 3F2 toward the vehicle outside to form a part at the vehicle rear side; and a rear wall 3H formed between end portions of the both side walls 3S1 and 3S2 on the vehicle outside.
Further, as shown in fig. 3, the front side flange 3F1 is smoothly inclined at the front edge 3M1 of the vehicle front side Fr so that the lower end thereof is closer to the vehicle front side Fr, where the width of the upper end of the front side flange SF1 is wider and the width of the vertical middle portion thereof is wider toward the lower side. The lower end of the bulging portion 3B on the lower end side portion of the front side flange 3F1 projects toward the vehicle front side. For this reason, the width of the lower end of the front flange 3F1 is narrower than the width of the vertically intermediate portion of the front flange 3F 1. The rear flange 3F2 is formed to have a substantially uniform width throughout its entire vertical length.
The lower end of the first reinforcing member 3 is fixed to the reinforcing member 8 so as to reinforce the lower end thereof. Next, the structure of the reinforcement member 8, the connecting structure of the reinforcement member 8 to the first reinforcing member 3, and the like will be described in detail.
[ Structure of second reinforcing member 4 ]
The second reinforcement member 4 is a member that reinforces the intermediate pillar, and is arranged within the closed section of the intermediate pillar. In detail, the second reinforcing member 4 is located on the vehicle inner side W1 of the first reinforcing member 3. As shown in fig. 2, the second reinforcing member 4 is formed to have a circular-arc-shaped longitudinal section that smoothly protrudes outward toward the vehicle outer side W2, and is formed to have a U-shaped section that opens toward the vehicle inner side W1, and as shown in fig. 4, the second reinforcing member 4 includes: a side wall 4S1 forming a part on the vehicle front side; a side wall 4S2 forming a part on the vehicle rear side; a rear wall 4R formed between the two side walls 4S1 and 4S 2. At this time, the second reinforcing member 4 is formed along the outer panel 1 and the first reinforcing member 3 in a state where the vertical length of the second reinforcing member 4 is set shorter than the vertical length of the first reinforcing member 3. That is, the lower end of the second reinforcing member 4 is located above the lower end of the first reinforcing member 3, and the upper end of the second reinforcing member 4 is located below the upper end of the first reinforcing member 3. Further, the second reinforcing member 4 is arranged substantially within the inner space of the bulged portion 3B of the first reinforcing member 3, and the sectional shape is sized to be accommodated in the inner space of the bulged portion 3B.
[ Structure of inner panel 2 ]
The inner panel 2 is a panel member that forms a part of the center pillar closed cross-sectional structure on the vehicle inner side W1, and is located on the vehicle inner side W1 of the first reinforcement member 3 and the second reinforcement member 4. As shown in fig. 1, 2, 5, and 6, the inner panel 2 is formed to have a hat-shaped cross section, including: a front side flange 2F1 (corresponding to the front edge) extending in the longitudinal direction of the vehicle from the vehicle front side Fr; a rear side flange 2F2 (corresponding to a rear edge) extending from the vehicle rear side in the longitudinal direction of the vehicle; a raised portion 2B formed therebetween. At this time, the bulging portion 2B bulges toward the vehicle inner side W1 with respect to the front side flange 2F1 and the rear side flange 2F 2. Further, the amount of projection of the bulged portion 2B of the inner panel 2 (the height of the bulged portion with respect to the flange) is set smaller than the amount of projection of the bulged portion 313 of the first reinforcement member 3, and the vertical length of the inner panel 2 is set shorter than the vertical length of the first reinforcement member 3. The upper end of the inner panel 2 is located near the upper ends of the first reinforcement member 3 and the outer panel 1, and is arranged up to the lower end of the roof side rail closed section. As shown in fig. 5, in the bulging portion 2B of the inner panel 2, both ends (ends in the vehicle longitudinal direction) in the lateral direction are formed to have a trapezoidal cross section, and the amount of bulging of the trapezoidal shape is larger than the amount of bulging of the bulging portion between both ends.
[ structures of the outer panel 1, the inner panel 2, the first reinforcing member 3, the second reinforcing member 4, and the reinforcing member 8 ]
[A] Connection structure of first reinforcing member 3 and second reinforcing member 4
As shown in fig. 3, 4 and 5, both side walls 3S1 and 3S2 of the bulging portion 3B of the first reinforcing member 3 are weld-connected to both side walls 4S1 and 4S2 of the second reinforcing member 4, respectively, and the rear wall SR is weld-connected to the rear wall 4H in a state where the upper half portion of the rear wall 3H formed between both side walls 3S1 and 3S2 of the first reinforcing member 3 is overlapped on the upper half portion of the rear wall 4H formed between both side walls 4S1 and 4S2 of the second reinforcing member 4. Further, the lower halves of the rear walls 3H and 4H are separated from each other, and a closed section is formed by the side walls 3S1, 3S2 and the rear walls 3H, 4H. The lower end of the rear wall 4H of the second reinforcing member 4 is welded to the rear wall 3H together with the upper end of the reinforcing member 8.
[B] Connection structure of inner panel 2, first reinforcing member 3 and outer panel 1
As shown in fig. 5, the front side flange 2F1 and the rear side flange 2F2 of the inner panel are overlapped on the front side flange 3F1 and the rear side flange 3F2, respectively, of the first reinforcing member 3 from the vehicle inner side W1 so as to form the first connecting portion 11 and the second connecting portion 12. In the first connection portion 11 and the second connection portion 12, a welding operation is performed through the first welded connection portion 21 and the second welded connection portion 22.
Further, the front side flange 3F1 of the first reinforcement member 3 is provided with a front side extension portion 3a1, the front side extension portion 3a1 extending from the first connection portion 11 between the front side flange 3F1 of the first reinforcement member 3 and the front side flange 2F1 of the inner panel 2 toward the vehicle front side Fr. The front side extension portion 3a1 is overlapped on the front side flange 1F1 of the outer panel 1 to form the third connection portion 13, and the welding operation is performed through the third welded connection portion 23. In the same manner, the rear side flange 3F2 of the first reinforcement member 3 is provided with a rear side extension portion 3a2, which rear side extension portion 3a2 extends toward the vehicle rear side from the second connection portion 12 between the rear side flange 3F2 of the first reinforcement member 3 and the rear side flange 2F2 of the inner panel 2. The rear side extension 3a2 is overlapped on the rear side flange 1F2 of the outer panel 1 to form the fourth connection part 14, and the welding operation is performed through the fourth welded connection part 24. Further, in the first welded connection portion 21 and the second welded connection portion 22, the front side flange 1F1 and the rear side flange 1F2 of the outer panel 1 are separated from the front side flange 3F1 and the rear side flange 3F2 of the first reinforcing member 3.
As shown in fig. 6, near the upper end of the intermediate pillar, the front side flange 2F1 of the inner panel 2, the front side flange 3F1 of the first reinforcing member 3, and the front side flange 1F1 of the outer panel 1 overlap each other, and three pieces of the front side flanges are spot-welded together (portions indicated by black square marks in fig. 6). In the same manner, the rear side flange 2F2 of the inner panel 2, the rear side flange 3F2 of the first reinforcing member 3, and the rear side flange 1F2 of the outer panel 1 overlap each other, and three pieces of the rear side flanges are spot-welded (portions indicated by black square marks in fig. 6). Further, at a portion on the vehicle front side below the vicinity of the upper end of the center pillar, the first connecting portion 11 is formed of a plurality of first welded connecting portions 21 (portions indicated by black circular marks in fig. 6), the first welded connecting portions 21 being spot-welded and arranged in the vertical direction of the vehicle with spaces therebetween. The third connecting portion 13 between the front side extending portion 3a1 of the first reinforcing member 3 and the front side flange 1F1 of the outer panel 1 is formed of a plurality of third welded connecting portions 23 (portions indicated by "+" in fig. 6), the third welded connecting portions 23 being spot-welded and arranged at intervals from each other. Further, at a lower portion of the upper end of the first reinforcing member 3, the first weld-joined portion 21 and the third weld-joined portion 23 are offset from each other in the vertical direction of the vehicle, and the first weld-joined portion 21 and the third weld-joined portion 23 are alternately arranged in the vertical direction of the vehicle. In other words, the first weld-joined portion 21 is located at a position different from the position where the third weld-joined portion 23 is located in the vertical direction of the vehicle. The plurality of first solder connection portions 21 and the plurality of third solder connection portions 23 are arranged at different height positions, not at the same height position.
At a portion on the vehicle rear side below the vicinity of the upper end of the center pillar, the second connection portion 12 is formed of a plurality of second welded connection portions 22 (portions indicated by black circles in fig. 6), the second welded connection portions 22 being spot-welded and arranged at intervals from each other in the vehicle vertical direction. The fourth connecting portion 14 between the rear side extending portion 3a2 of the first reinforcing member 3 and the rear side flange 1F2 of the outer panel 1 is formed of a plurality of fourth welded connecting portions 24 (portions indicated by "+" in fig. 6), the fourth welded connecting portions 24 being spot-welded and arranged at intervals from each other. Further, in the upper half portion (except for the upper end) of the first reinforcing member 3, the second weld-joined portions 22 and the fourth weld-joined portions 24 are offset from each other in the vertical direction of the vehicle, and the second weld-joined portions 22 and the fourth weld-joined portions 24 are alternately arranged in the vertical direction of the vehicle. In other words, the second weld-joined portion 22 is located at a position different from the fourth weld-joined portion 24 in the vertical direction of the vehicle. The plurality of second solder connection portions 22 and the plurality of fourth solder connection portions 24 are arranged at different height positions, not at the same height position.
Further, in the lower half of the first reinforcing member 3 and the lower half of the inner panel 2, the rear side flange 2F2 of the inner panel 2, the rear side flange 3F2 of the first reinforcing member 3, and the rear side flange 1F2 of the outer panel 1 overlap each other, and three pieces of the rear side flanges are spot-welded (portions indicated by black triangles in fig. 6).
As shown in the enlarged view of fig. 6, one portion 2E1 of the front edge of the inner panel 2 in one of the first weld-joined portions 21 projects toward the vehicle front side Fr with respect to the other portion 2G1 of the front edge of the inner panel 2. That is, in one first weld-joined portion 21 and one third weld-joined portion 23 that are adjacent to each other in the vertical direction of the vehicle, the front edge 2E1 of the inner panel 2 on the vehicle front side Fr in one of the first weld-joined portions 21 projects toward the vehicle front side Fr from the front edge 2G1 on the vehicle rear side of one of the third weld-joined portions 23. A portion 2E2 of the rear edge of the inner panel 2 in one of the second weld-joined portions 22 projects toward the vehicle rear side with respect to the other portion 2G2 of the rear edge of the inner panel 2. That is, in one of the second weld-joined portions 22 and the fourth weld-joined portions 24 that are adjacent to each other in the vertical direction of the vehicle, the rear edge 2E2 of the inner panel 2 on the vehicle rear side in one of the second weld-joined portions 22 is more protruded toward the vehicle rear side than the rear edge 2G2 on the vehicle front side Fr in one of the fourth weld-joined portions 24.
Further, a portion 3E3 of the front edge of the first reinforcing member 3 in one of the third weld connecting portions 23 projects toward the vehicle front side Fr with respect to the other portion 3G3 of the front edge of the first reinforcing member 3. That is, in one first weld-joined portion 21 and one third weld-joined portion 23 which are adjacent to each other in the vertical direction of the vehicle, the front edge 3E3 of the first reinforcing member 3 at the vehicle front side Fr in one of the third weld-joined portions 23 projects toward the vehicle front side Fr from the front edge 3G3 at the vehicle front side Fr in one of the first weld-joined portions 21. A portion 3E4 of the rear edge of the first reinforcing member 3 in one of the fourth weld-joined portions 24 projects toward the vehicle rear side with respect to the other portion 3G4 of the rear edge of the first reinforcing member 3. That is, in one second welded joint portion 22 and fourth welded joint portion 24 adjacent to each other in the vertical direction of the vehicle, the rear edge 3E4 of the first reinforcing member 3 on the vehicle rear side in one of the fourth welded joint portions 24 projects toward the vehicle rear side from the rear edge 3G4 on the vehicle rear side of one of the second welded joint portions 22.
As shown in fig. 1, 2 and 6, the lower end of the inner panel 2 is not connected to the side seals, the lower end 2K of the inner panel 2 is disposed on the upper side Z1 so as to have a clearance from the upper end 20J of the side seal inner panel 20, and then an opening is formed between the lower end 2K of the inner panel 2 and the upper end 20J of the side seal inner panel 20, thereby forming a retractor accommodating space S in the cross section of the center pillar so as to be opened toward the vehicle inside. Further, the retractor 61 of the seatbelt is accommodated in this retractor accommodating space S, and the attaching portion 63 formed on the retractor 61 is overlapped on the retractor attaching portion 62 formed at the lower end of the inner panel 2 from the vehicle inside W1. Next, the attachment bolt 64 is inserted through a bolt insertion hole 62H (see fig. 6) of the retractor attachment portion 62 and a bolt insertion hole of the retractor 61 attachment portion 63 so as to be screwed to a nut 65 formed on the rear surface of the retractor attachment portion 62. In the present embodiment, since the inner panel 2 is not disposed below the retractor attaching portion 62, it is possible to further reduce the weight and easily change the deformation mode of the center pillar. Further, the lower end of the inner panel 2 may be provided with a groove or the like so as to enlarge the opening. According to such a configuration, retractor attachment portion 62 may be disposed above the slot.
[C] Connection structure of reinforcement member 8, first reinforcing member 3, and second reinforcing member 4
As shown in fig. 2, the reinforcement member 8 is fixed to the lower end of the reinforcement member 3 so as to reinforce the lower end of the first reinforcement member 3, where the reinforcement member 8 is located on the vehicle outer side W2 of the retractor 61 and the lower end 8K is located below the lower end 2K of the inner panel 2, and then the reinforcement member 8 is thicker than the second reinforcement member 4. Further, the upper end of the reinforcement member 8 is located above the lower end 2K of the inner panel 2. That is, in these embodiments, since the inner panel 2 is disposed just up to the middle position of the center pillar, the reinforcement member 8 is disposed on the vehicle outer side of the lower end 2K. Further, in the present embodiment, the lower end 8K is not directly connected to the member forming the side seal, and the lower end 8K is arranged on the upper side Z1 so as to leave a gap from the upper end 18F1 of the side seal strength member 18 to be described later. As shown in fig. 7(a) and 7(b), the reinforcing member 8 is formed to have a hat-shaped cross section, and includes: a front side flange 8F1 forming a part on the vehicle front side Fr; a rear side flange 8F2 forming a part on the vehicle rear side; a raised portion 8B formed therebetween. The width of the reinforcement member 8 in the longitudinal direction of the vehicle widens toward the lower end of the reinforcement member 8.
Further, the rear wall 8H formed between the two side walls 8S1 and 8S2 of the bulged portion 8B of the reinforcement member 8 is superposed on the rear wall 8H between the two side walls 3S1 and 3S2 of the bulged portion 3B of the first reinforcing member 3 from the vehicle inner side W1 so as to be weld-connected to each other. The front side flange 8F1 and the rear side flange 8F2 of the reinforcement member 8 are overlapped on the front side flange 3F1 and the rear side flange 3F2 of the first reinforcing member 3, respectively, from the vehicle inner side W1 so as to be welded and connected to each other. As shown in the enlarged view of fig. 2, the lower end of the rear wall 4H of the second reinforcing member 4 is inserted between the rear wall 8H of the bulged portion 8B of the reinforcing member 8 and the rear wall 3H of the bulged portion 3B of the first reinforcing member 3 so as to be integrally weld-connected to each other.
Reference character H in fig. 2 denotes a rear door hinge attachment hole formed through the reinforcement member 8, the first reinforcement member 3, and the outer panel 1 that overlap each other. Reference numeral 66 denotes a weld portion formed in the reinforcement member 8 and the first reinforcement member 3 so as to project toward the vehicle inside. The weld portions 66 are used to facilitate deformation of the center pillar with respect to an impact load applied from the side of the vehicle. Further, the weld portion 66 formed in the reinforcement member 8 is continuously formed to the side wall 8S2 and the rear wall 8H, and is used to change the deformation mode of the intermediate pillar by changing the load of open deformation of the hat-shaped section of the reinforcement member 8.
With such a configuration, when an impact load is applied to the center pillar from the side thereof, the lower portion of the center pillar without the inner panel 2 is deformed so that the deformed position is located below the center pillar, and the impact load is absorbed so as to suppress the amount of deformation to be minimally directed toward the vehicle inner side. That is, at the lower portion of the center pillar, the plate member is disposed only on the vehicle outside (on the side portion of the outer panel) of the retractor 61 so as to form an opening section, and the inner panel 2 that connects the flanges of the plate member having a hat-shaped section to each other is not provided between the flanges. Therefore, the lower portion of the middle pillar can be deformed more easily than the other portions. Further, the lower portion of the center pillar is provided with the relatively small-sized reinforcement member 8, so that the deformation load thereof can be easily changed by changing the shape of the reinforcement member 8 or the thickness of the sheet.
As shown in fig. 8, the attachment base portions 10 of the pair of opening modifications are attached to the outer side portions of the third connecting portion 13 and the fourth connecting portion 14 from the vehicle front side Fr and the vehicle rear side, respectively. A pair of front-rear attachment portions 53 having an L-shaped cross section formed in the middle pillar trim 5 are attached to the outer peripheral portion of the opening trim 10 having an L-shaped cross section. The pillar garnish 5 covers the first reinforcement member 3, the second reinforcement member 4, and the inner panel 2. Further, the center pillar garnish 5 covers the front side flange 1F1 and the rear side flange 1F2 of the outer panel 1 from the vehicle inner side W1.
[ welding Process of connecting Structure ]
The welding process of the connection structure is as follows (detailed description of welded connection is shown in [ A ] to [ C ]).
(1) The first reinforcing member 3, the second reinforcing member 4, and the reinforcing member 8 are welded to each other.
(2) The inner panel 2 is welded and connected to the product of (1). That is, the inner panel 2 is weld-connected to the first reinforcement member 3, and the lower end 2K of the inner panel 2 is weld-connected to the overlapping portion between the first reinforcement member 3 and the reinforcement member 8.
(3) The product of (2) is welded to the outer panel 1. That is, the first reinforcement member 3 (including the overlapped inner panel 2 or the reinforcement member 8 depending on the position) is welded to the outer panel 1, thereby forming the side body. Then, the side body is connected to the lower part body to which the main floor 16, the side seal inner panel 20, and the like are attached.
[ Structure of side seal 50 ]
As shown in fig. 2, the outer panel 1 extends in the longitudinal direction of the vehicle at the lower end of the center pillar, and is bent such that the U-shaped cross section opens toward the vehicle inside W1 and bulges toward the vehicle outside W2. The bottom wall 15 of the U-shaped cross-sectional lower end extends toward the vehicle inside W1 with respect to the upper wall 45 so as to form a flange 15F extending from the extended end. Further, the side seal rear reinforcement member 17 is built in by using the flanges 20F1, 20F2 at the upper and lower ends of the side seal inner panel 20 and the flanges 18F1 and 18F at the upper and lower ends of the side seal strength member 18, wherein the side seal inner panel 20 extends in the longitudinal direction of the vehicle and has a hat-shaped cross section that opens toward the vehicle outer side W2 when viewed from the vehicle front side Fr, and the side seal strength member 18 extends in the longitudinal direction of the vehicle and has a hat-shaped cross section that opens toward the vehicle inner side W1 when viewed from the vehicle front side Fr.
Further, in the lower end of the center pillar, the flange 18F1 of the upper end of the side seal strength member 18, the upper end of the side seal rear reinforcement member 17, and the flange 20F1 of the upper end of the side seal inner panel 20 are welded to each other. Further, the flange 15F of the outer panel 1 is overlapped on the lower end flange 18F2 of the side seal strength member 18. The flange 15F of the outer panel 1, the flange 18F2 at the lower end of the side seal strength member 18, the lower end of the side seal reinforcing member 17, and the flange 20F2 at the lower end of the side seal inner panel 20 are welded to each other. The lower end 3K of the reinforcement member 3 is superposed on the lower end of a rear wall 18H formed in the vertical direction of the side seal strength member 18 from the vehicle outside W2 so as to be welded to each other to form the side seal 50. The side seal inner panel 20 and the side seal strength member 18 form a closed section, and the closed section is divided into two parts in the lateral direction (vehicle lateral direction) by the side seal reinforcing member 17. Further, on the front and rear sides of the center pillar, the flanges of the outer panel 1 are overlapped on the flange 18F1 of the upper end of the side seal strength member 18, the upper end of the side seal rear reinforcement member 17, and the flange 20F1 of the upper end of the side seal inner panel 20 so as to be welded and connected thereto, thereby forming a closed cross section of the side seal. Further, reference numeral 67 in fig. 2 denotes a seat-belt anchor nut.
The lower end of a rear wall 20H formed in the vertical direction of the side seal inner panel 20 overlaps a flange 16F of the main floor 16 (corresponding to the vehicle body) formed at the end of the vehicle outside W2, the flange 16F extending toward the upper side Z1, and the lower ends of the rear wall 20H and the vehicle inside W1 are welded to each other (see fig. 2).
As shown in fig. 1, a pair of left and right seat rails 28 that slidably support a vehicle seat 29 in the vehicle length direction are supported on the main floor 16 by a pair of left and right front seat brackets 27 and a pair of left and right rear seat brackets 26.
As shown in fig. 6, the pair of right and left rear seat brackets 26, which are interposed between the rear ends of the seat rails 28 and the main floor 16 so as to connect the rear ends to the main floor 16, are fixed to the side seal inner panel 20 at positions offset from the center axis O of the lower end of the outer panel 1 toward the vehicle front side Fr in the vehicle longitudinal direction. That is, the seat bracket 26 is arranged on the vehicle front side Fr with respect to the center axis O.
Further, the seat brackets 26 and 27 are formed to have a hat-shaped section open toward the lower side, and flanges at the lower ends of rear walls (walls disposed on the vehicle rear side, not shown in the drawings) and flanges 26F1 and 27F1 at the lower ends of front walls 26M1 and 27M1 (walls disposed on the vehicle front side Fr) are overlapped on the main floor 16 from the upper side Z1 so as to be welded to the main floor 16. A front wall 27M1 on the vehicle outside W2 of the seat bracket 27 between the pair of left and right front seat brackets 27 and a flange 27F2 formed on the vehicle outside end portion of the rear wall overlap on the side seal inner panel 20 from the vehicle inside W1 so as to be welded to the side seal inner panel 20.
The front wall 26W of the seat bracket 26 on the vehicle outer side W2 between the pair of left and right rear seat brackets 26, the flange 26F2 of the seat bracket 26 formed between the pair of left and right rear seat brackets 26 on the front wall 26M1 and the end of the rear wall on the vehicle outer side W2, and the flange 26F3 formed on the end of the upper wall 26J of the seat bracket 26 on the vehicle outer side and extending toward the upper side Z1 overlap the side seal inner panel 20 from the vehicle inner side W1 so as to be welded to the side seal inner panel 20.
With such a configuration, when an impact load is applied to the center pillar from the vehicle side portion, the deformation position of the center pillar toward the vehicle interior can be set to a position at the rear side of the vehicle seat 29, thereby reducing the influence of the center pillar deformation on the seat 29. Further, the side seal is reinforced by the pair of left and right rear seat brackets 26, so that deformation of the side seal toward the vehicle interior is suppressed, thereby ensuring a space for the seat 29.
[ other examples ]
(1) In the above-described embodiment, the reinforcement member of the center pillar on the vehicle inner side is divided into the upper and lower reinforcement members, and the rigidity of the lower reinforcement member (reinforcement member 8) is set to be greater than the rigidity of the upper reinforcement member (second reinforcement member 4). However, the second reinforcing member 4 and the reinforcing member 8 forming the reinforcing member portion may also be formed integrally with each other by cutting a blank material (tailoraded blank material) formed by welding plate members having different thicknesses to each other. That is, a plate member corresponding to the second reinforcing member 4 and a reinforcing member plate member corresponding to the reinforcing member 8 are provided, and the plate member corresponding to the reinforcing member 8 may be formed by cutting a blank material to a thickness thicker than that of the plate member corresponding to the second reinforcing member 4, thereby forming a reinforcing member portion.
(2) The welded connection in the above-described embodiment corresponds to spot welding.
