The present invention relates to a vehicle body side structure including a seal member for covering a coupling recessed portion formed on a surface of a vehicle by coupling a plurality of outer panels.
Among this type of vehicle body side structures, there is a structure for coupling a portion extending from a roof to an upper portion of a center pillar. A center pillar is plastically formed as a separate body by using a high tension steel plate, a roof rail is plastically formed by using a normal steel plate, and a vehicle body outer panel coupling portion couples the center pillar and the roof rail near the roof rail (e.g., refer to Patent Literature 1).
There is also a vehicle body in which coupled portions are covered. In this vehicle body, respective pillars such as a center pillar are divided into upper and lower two portions. Stepped portions are formed at boundary portions where the upper portions and the lower portions are coupled and seal tape is stuck to the stepped portion, with which a seal member provided to a door comes in contact, out of the stepped portions (e.g., refer to Patent Literature 2).
However, an outward appearance of the vehicle body side structure disclosed in Patent Literature 1 is not good, because a step is formed by a plate material laid on the coupling portion between the upper portion of the center pillar and the roof rail or a welding mark remains.
In the vehicle body side structure disclosed in Patent Literature 2, the seal tape is stuck only to a position corresponding to the seal member provided to the door and therefore seal tape does not exist at the remaining stepped portions.
In this manner, the stepped portions formed at the coupling portions are exposed and remain, which detracts from visual quality. If large seal tape adapted to the remaining stepped portions is used to cover the remaining stepped portions, thin edges of the seal tape (seal member) corrugate and it is difficult to carry out the operation. Moreover, the thin edges of the seal tape (seal member) may not uniformly come in contact, which may detract from visual quality.

It is an object of the present invention to provide a vehicle body side structure which improves visual quality, even when a center pillar outer member or panel is divided into two portions, and facilitates a mounting operation of a seal member.
According to a first aspect of the present invention, there is provided a vehicle body side structure in which a center pillar outer member of a center pillar supporting a roof of a vehicle body is divided into two portions, i.e., a center pillar outer member upper portion and a center pillar outer member lower portion and a front door opening seal and a rear door opening seal corresponding to a front door and a rear door are mounted to a roof side rail continuous from the center pillar and the roof and extending in a front-back direction of the vehicle body, the vehicle body side structure including: a coupling recessed portion where the center pillar outer member lower portion is coupled to the center pillar outer member upper portion; and a seal member for covering the coupling recessed portion, wherein the seal member is continuous with a front upper seal and a rear upper seal, along the roof side rail, of the front door opening seal and the rear door opening seal.
In a second aspect of the invention, preferably, the seal member includes a main body portion facing the coupling recessed portion, a first lip portion continuous with the main body portion and to be laid on an outer face of the center pillar outer member upper portion, and a second lip portion continuous with the main body portion and to be laid on an outer face of the center pillar outer member lower portion, a front door seal on a side of the door and extending along the center pillar outer member comes in close contact with the center pillar outer member, a seal line area of the seal member is formed to have a smooth surface shape without steps from the main body portion to a tip end of the first lip portion and a tip end of the second lip portion and between the tip ends and the center pillar outer member, and a remaining tip end other than the tip ends in the seal line area is formed to be thick-walled.
In a third aspect of the invention, the seal member is preferably stuck to the coupling recessed portion.
In a fourth aspect of the invention, the seal member preferably has one end pinched by the front door opening seal and the other end pinched by the rear door opening seal.
In a fifth aspect of the invention, preferably, the center pillar outer member lower portion has a recessed portion formed by pressing an upper portion of the center pillar outer member lower portion toward a vehicle interior, the center pillar outer member upper portion has a roof rail coupling T-shaped portion continuous with the recessed portion, extending in a longitudinal direction of the roof side rail, and coupled to an outer face of a stiffener which is provided inside a roof rail outer plate of the roof side rail and which has a closed section, the coupling recessed portion is formed by coupling a stepped portion, formed by bending a lower portion of the center pillar outer member upper portion of the roof rail outer plate toward the vehicle interior, to the recessed portion, and the coupling recessed portion is disposed at substantially the same height as a front door opening upper edge and a rear door opening upper edge to which the front upper seal and the rear upper seal are respectively mounted and which are included in the roof side rail.
In the first aspect of the invention, the center pillar outer member of the center pillar is divided into the two portions, i.e., the center pillar outer member upper portion and the center pillar outer member lower portion and the vehicle body side structure includes the coupling recessed portion where the center pillar outer member lower portion is coupled to the center pillar outer member upper portion and the seal member for covering the coupling recessed portion. The seal member is continuous with the front upper seal and the rear upper seal, along the roof side rail, of the front door opening seal and the rear door opening seal. Therefore, the seal member is continuous with the door opening seal and aligned with the door opening seal in a height direction of a vehicle. The seal member can be provided continuously with the door opening seal, which avoids a feeling of strangeness caused by an outward appearance of the coupling recessed portion and improves visual quality.
In second aspect of the invention, the seal member includes the main body portion, the first lip portion, and the second lip portion. The seal line area of the seal member to which the door seal on the side of the door comes in contact is formed to have the smooth surface shape without the steps from the main body portion to the tip end of the first lip portion and the tip end of the second lip portion and between the tip ends and the center pillar outer member and the remaining tip end other than the tip ends in the seal line area is formed to be thick-walled. Because the tip end is thick-walled, shapes of the thin tip ends in the seal line area can be maintained, falling off of the thin tip ends in the seal line area from the outer face of the center pillar outer member upper portion and the outer face of the center pillar outer member lower portion can be suppressed, and the tip ends in the seal line area can be brought into close contact with the outer faces.
In the third aspect of the invention, the seal member is stuck to the coupling recessed portion, which facilitates a mounting operation of the seal member.
In the fourth aspect of the invention, the seal member has one end pinched by the front door opening seal and the other end pinched by the rear door opening seal. Therefore, the one end and the other end of the seal member become less liable to fall off from the center pillar outer member and detachment of the one end and the other end can be suppressed. Moreover, a line continuous with the door opening seals becomes clearer, which further improves visual quality.
In the fifth aspect of the invention, the recessed portion is formed by pressing the upper portion of the center pillar outer member lower portion toward the vehicle interior and the roof rail coupling T-shaped portion coupled to the outer face of the stiffener of the roof side rail is formed continuously with the recessed portion. The coupling recessed portion is formed by coupling the stepped portion, formed by bending the lower portion of the center pillar outer member upper portion toward the vehicle interior, to the recessed portion. The coupling recessed portion is disposed at substantially the same height as the front door opening upper edge and the rear door opening upper edge. Therefore, it is possible to couple the upper portion of the center pillar to the stiffener (the roof side rail reinforcing member) of the roof side rail without reducing an area of the closed section extending to the upper portion of the center pillar to thereby increase strength against a load input to the roof from above the roof.
Furthermore, because the coupling recessed portion is disposed at substantially the same height as the front door opening upper edge and the front door opening upper edge, a feeling of strangeness caused by an outward. appearance of the coupling recessed portion can be reduced.
A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
As illustrated in
The side body 13 includes a side sill 18, a front pillar 21 rising from the side sill 18, a center pillar 22, a rear pillar 23, and a roof side rail 24. The side body 13 has a front door opening 25 formed by the side sill 18, the pillars 21 and 22, and the roof side rail 24 and a rear door opening 26 formed by the side sill 18, the pillars 22 and 23, and the roof side rail 24.

Furthermore, the roof side rail 24 includes an opening upper end portion 111 which is continuous with the roof rail outer plate main body portion 106 and has a face oriented downward, an outer flange 112 which is continuous with the opening upper end portion 111 and included in the front door opening upper edge 76, and an outer flange 77a which is included in the rear door opening upper edge 77. At a center in a longitudinal direction of the opening upper end portion 111, the center pillar outer member upper portion 37 is formed.
The center pillar outer member upper portion 37 has the stepped portion 75 formed by bending the second main body wall portion (the lower portion 74) at a center, the second main body wall portion (the lower portion 74) disposed to he an extension of the main body wall portion 85 of the center pillar outer member 36. As illustrated in
As illustrated in
The stiffener outer 116 has a substantially U-shaped section and includes a stiffener first wall portion 121 along the roof rail outer plate main body portion 106 of the center pillar outer member 36, a stiffener second wall portion 122 extending from the stiffener first wall portion 121 toward the roof 17, a stiffener third wall portion 123 facing the stiffener second wall portion 122, and a flange 124 continuous with the stiffener third wall portion 123. The stiffener second wall portion 122 is coupled to the coupling end 108 of the top portion 107 of the roof rail outer plate 68 by spot welding (welded portions 125).

A thickness of the first lip portion 48 gradually reduces from thickness t1 of the first lip portion 48 of the seal line area 55 to thickness t2 (not illustrated, e.g., 0.01 mm) of the tip end 56. A thickness of the second lip portion 52 gradually reduces from thickness t1 of the second lip portion 52 of the seal line area 55 to thickness t2 (e.g., 0.01 mm) of the tip end 57.
On the other hand, a thickness of the remaining first lip portion 48 other than the first lip portion 48 of the seal line areas 55 gradually reduces from thickness t1 to thickness t3 (e.g., 0.5 mm) of the tip end 58 (
A thickness of the remaining second lip portion 52 other than the second lip portion 52 of the seal line areas 55 gradually reduces from thickness t1 to thickness t3 (e.g., 0.5 mm) of the tip end 61 (
As illustrated in
Next, a mounting procedure of the seal member 42 will be briefly described.
First, a painting step of the vehicle body 12 is completed. Here, a coating is not illustrated. Next, as illustrated in
Lastly, when the front door opening seal 31 and the rear door opening seal 33 are mounted to the vehicle body 12, the grasping portion 136 of the front door opening seal 31 is laid on the one end 63 of the seal member 42 to thereby pinch the one end 63. Similarly, the grasping portion 136 of the rear door opening seal 33 is laid on the other end 64 of the seal member 42 to thereby pinch the other end 84. This ends the mounting of the seal member 42.
In this manner, in the vehicle body side structure, the seal member 42 is continuous with the front upper seal 43 of the front door opening seal 31 and the rear upper seal 44 of the rear door opening seal 33 and the same in color as the door opening seal. In this manner, it is possible to avoid a feeling of strangeness caused by outward appearances of the seal member 42 and the coupling recessed portion 41 to thereby improve visual quality.
Moreover, because the seal member 42 is stuck after the vehicle body 12 is painted, it is easy to obtain the seal member 42 in the same color as the front door opening seal 31 and the rear door opening seal 33. However, it is also possible that the seal member 42 is in the same color as the center pillar 22.
Furthermore, because the remaining tip ends 58 and 61 of the seal member 42 are thick-walled (thickness t3), shapes of the thin tip ends 56 and 57 in the seal line areas 55 can be maintained, falling off of the thin tip ends 56 and 57 in the seal line areas 55 from the outer face 47 of the center pillar outer member upper portion 37 and the outer face 51 of the center pillar outer member lower portion 38 can be suppressed, and the tip ends 56 and 57 in the seal line areas 55 can be brought into close contact with the outer faces 47 and 51.
