Description

  The present invention relates to a roof side structure of a vehicle body.

  Conventionally, in order to cope with loads from the front-rear direction, the side direction, and the upward direction, it has been desired to give the vehicle body high strength (rigidity). For example, Patent Document 1 discloses a side body structure that improves the rigidity of a pillar portion and a side sill portion. Further, in the vehicle body structure disclosed in Patent Document 2, a displacement portion is provided between a portion that functions as an outer panel of the body side panel and a portion that functions as an inner panel. A front end portion of the reinforcement is joined to the displacement portion in a face-to-face relationship, thereby improving the rigidity of the vehicle body.

  When a load in the vertical direction is applied to the upper part of the vehicle body, it is necessary to ensure high rigidity of the vehicle body with respect to the load applied in the vertical direction in order to maintain the space in the vehicle interior. One means for this is to increase the rigidity of the roof side structure.

  However, the technique such as Patent Document 1 cannot improve the rigidity of the roof side structure. This is because the technique of Patent Document 1 improves the rigidity of the pillar part and the side sill part (vehicle body side part) and does not take any measures to improve the rigidity of the roof side structure (car body upper part).

  In the technique such as Patent Document 2, it is considered that the rigidity of the roof side structure is improved to some extent. However, there is a need for a roof side structure with even higher rigidity. Moreover, since the technique of patent document 2 needs to bend a body side panel and weld to the front end part etc. of reinforcement, there exists a possibility that a process location may increase and the burden concerning a manufacturing site may increase.

  When further increasing the rigidity of the roof side structure, care must be taken to make the roof side structure so that the electrodeposition liquid and cleaning liquid adhering to the dipping process in the car body painting line do not accumulate. . This is because when the electrodeposition liquid or the cleaning liquid tends to accumulate (the discharge speed decreases), foreign matters such as iron powder and dust attached to the vehicle body may not be removed and may be brought into a subsequent process. Moreover, it is also because there is a possibility that the deposition of the electrodeposition liquid becomes worse and the finish of the coating may vary.

  The present invention has been made in view of such problems, and while ensuring high rigidity, the electrodeposition liquid and cleaning liquid adhering to the immersion process in the vehicle body painting line are not stored. An object is to provide a roof side structure.

  In order to solve the above-described problems, a representative configuration of the present invention includes a roof side inner panel installed between the side of the roof of the vehicle body and the side of the vehicle body, and a vehicle body on the outside of the vehicle body rear portion of the roof side inner panel. A roof side structure of a vehicle body including a roof side rear reinforcement that is mounted over the front and rear direction and reinforces the roof side inner panel, and the roof side rear reinforcement extends in the vehicle longitudinal direction and is fixed to the roof side inner panel. Two side-by-side vehicle body mounting surfaces, two upright surfaces that stand substantially vertically from the inside of the two body mounting surfaces, and a projecting surface that connects the upper sides of the two upright surfaces, and the roof side The rear reinforcement is further characterized in that the two standing surfaces descend toward the rear of the vehicle body with respect to the horizontal plane.

  According to the above configuration, the roof side rear reinforcement whose cross section is bent into a hat shape is configured by the two vehicle body mounting surfaces, the two standing surfaces, and the protruding surfaces. Such a bent cross-sectional shape reinforcement is remarkably higher in rigidity than a flat shape reinforcement. Therefore, the rigidity of the roof side structure can be further increased.

  On the other hand, according to the reinforce of the above shape, the electrodeposition liquid and the cleaning liquid adhering to the hat-shaped corners by the dipping process in the vehicle body painting line are likely to be accumulated. Thus, as described above, the roof side rear reinforcement is lowered toward the rear of the vehicle body with respect to the horizontal plane, so that the electrodeposition liquid is discharged along the descent. Therefore, according to the present invention, it is possible to provide a roof side structure of a vehicle body that ensures high rigidity and does not store electrodeposition liquid or cleaning liquid adhering to the immersion treatment in the vehicle body painting line. .

  The center line of the roof side rear reinforcement may be lowered toward the rear of the vehicle body with respect to the roof side inner panel. Thereby, since the center line of the roof side rear reinforcement has a vector in the vertical direction as well as the front and rear direction, the rigidity of the vehicle body skeleton can be further enhanced against the load applied in the vertical direction on the roof side.

  The roof side rear reinforcement may be descended along a curved locus convex upward. As a result, the upwardly curved portion has a rigidity improving effect against the load applied to the roof side from above, so that the rigidity of the vehicle body skeleton can be further increased.

  The roof side rear reinforcement is further mounted on the outside of the roof side inner panel in the front-rear direction of the vehicle body and further includes a roof side reinforcement that reinforces the roof side inner panel. It should be installed so that the rear part of the vehicle body overlaps. Thereby, sufficient rigidity can be secured even in front of the roof side rear reinforcement. In particular, since the roof side rear reinforcement and the roof side reinforcement are installed so as to overlap with each other, both members can be regarded as one body, and the joint portion can be prevented from becoming a weak point in strength.

  The roof side rear reinforcement may be attached across the roof side inner panel and a subsequent member connected to the rear end portion of the roof side inner panel. Thereby, connection with a roof side inner panel and a succeeding member can be reinforced suitably. That is, the load applied to the roof side in the vertical direction can be transmitted not only to the roof side inner panel but also to the subsequent member via the roof side rear reinforcement. Moreover, since the load from the back applied to a subsequent member can be efficiently transmitted also to a roof side inner panel, the absorbability of a load can be improved.

  According to the present invention, the electrodeposition liquid and the cleaning liquid adhered by the dipping process in the vehicle body painting line are not stored while securing the rigidity of the vehicle body skeleton against the load applied to the roof side in the vertical direction. A roof side structure of a vehicle body can be provided.

To do.

[Body side structure]
FIG. 1 is an exploded perspective view of a vehicle body side portion to which a roof side structure according to the present embodiment is applied. The vehicle body side portion 100 is constructed from a side body outer panel 110 and a side body inner panel 112 provided on the inside thereof.

  The side body inner panel 112 is constructed by combining a plurality of vehicle body skeleton members. For example, a front inner upper pillar 122 is disposed at the front portion of the vehicle body so as to be connected to the front door hinge reinforcement 120. A roof side inner panel 124 that connects a side portion of the roof (roof) of the vehicle body and the side surface of the vehicle body is connected to the upper end of the front inner upper pillar 122.

  A front pillar upper reinforcement 126 that reinforces the front inner upper pillar 122 and the roof side inner panel 124 is provided in parallel. Since the front inner upper pillar 122 and the front pillar upper reinforcement 126 constitute the side portion of the front windshield of the vehicle body, the front inner upper pillar 122 and the front pillar upper reinforcement 126 are lowered toward the front of the vehicle body along the horizontal plane.

  The electrodeposition liquid and the cleaning liquid adhering to the front inner upper pillar 122 and the front pillar upper reinforcement 126 are discharged by the dipping process in the vehicle body painting line along the shape descending forward of the vehicle body. In the case of a shape in which the electrodeposition liquid and the cleaning liquid are accumulated (the discharge speed is reduced), there is a possibility that foreign matters such as iron powder and dust attached to the vehicle body are not removed and are brought into a subsequent process. In addition, there is a risk that the electrodeposition liquid will not be applied well and the coating finish will vary.

  A center pillar inner panel 128 is connected substantially vertically in the middle of the roof side inner panel 124. A center pillar reinforcement 130 as a reinforcing material is provided outside the center pillar inner panel 128. These lower portions are connected to a side sill strength 132 whose front end is connected to the front door hinge reinforcement 120. The rear end of the side sill strength 132 is connected to the wheel house inner panel 136 and the wheel house outer panel 138 via the side sill rear panel 134. The pillar portion and the side sill portion ensure the rigidity of the vehicle body side portion or the vehicle body lower portion.

  A quarter inner extension 140 (subsequent member) is connected to the rear end portion of the roof side inner panel 124. A roof side reinforcement 142 and a roof side rear reinforcement 116 are provided on the outer sides of the roof side inner panel 124 to the quarter inner extension 140 in the longitudinal direction of the vehicle body.

  In a hatchback vehicle or the like, the lower side of the quarter inner extension 140 is connected to the quarter inner panel 146 substantially vertically to form a box-shaped cabin space. The quarter inner panel 146 is connected to the wheel house inner panel 136 via the quarter inner front reinforcement 148. The quarter wind lower member 150 is a reinforcing member provided below the window opening of the quarter inner panel 146. Behind these, a lamp house inner panel 152 that forms a part of the frame of the back door is provided.

[Roof side structure]
FIG. 2 is a diagram showing each component constituting the roof side structure according to the present embodiment in FIG. As shown in FIG. 2, the roof side structure 114 includes a roof side inner panel 124, a quarter inner extension 140, a roof side reinforcement 142, and a roof side rear reinforcement 116.

  The roof side rear reinforcement 116 is attached across the roof side inner panel 124 and the quarter inner extension 140 so that the two standing surfaces 156a and 156b descend toward the rear of the vehicle body with respect to the horizontal plane. In particular, in the present embodiment, the center line of the roof side rear reinforcement 116 forms an angle with respect to the roof side inner panel 124. Further, the roof side reinforcement 142 is attached to the outside of the roof side inner panel 124 so that the rear portion of the vehicle body overlaps the front end (front portion of the vehicle body) of the roof side rear reinforcement 116.

  FIG. 3 is a view showing a state in which the constituent elements of the roof side structure of FIG. 2 are assembled. 4 is a cross-sectional view taken along line AA in FIG. As shown in FIG. 3, in the roof side structure 114, the roof side rear reinforcement 116 is installed across the roof side inner panel 124 and the quarter inner extension 140, so that these connections are suitably reinforced. That is, the load applied to the roof side in the vertical direction can be transmitted to the quarter inner extension 140 not only through the roof side inner panel 124 but also through the roof side rear reinforcement 142. Moreover, since the load from the rear applied to the quarter inner extension 140 can be efficiently transmitted to the roof side inner panel 124, the load absorbability can be improved.

  Further, the roof side reinforcement 142 is superimposed on the front end of the roof side rear reinforcement 116. Therefore, both members can be regarded as one body, and it can be avoided that the joint portion becomes a strong weak point.

  The reason for using the roof side rear reinforcement 116 and the roof side reinforcement 142 as separate members is to share parts between the specification car with the setting of the roof side rear reinforcement 116 and the specification car without the setting. is there. As a result, it is possible to easily improve production efficiency, reduce costs, and adjust the rigidity balance at the rear of the vehicle body.

  As shown in FIG. 4, in the roof side rear reinforcement 116, two parallel vehicle body mounting surfaces 154 a and 154 b extend in the vehicle front-rear direction (see FIG. 3) and are fixed to the roof side inner panel 124. Then, two standing surfaces 156a and 156b stand up almost vertically from the inside of the two vehicle body mounting surfaces 154a and 154b, and the projecting surfaces 158 connect the upper sides of the standing surfaces 156a and 156b. The roof side rear reinforcement 116 forms a hat-shaped cross section by the two vehicle body mounting surfaces 154a, 154b, the two standing surfaces 156a, 156b, and the projecting surface 158.

  FIG. 7 is a cross-sectional view illustrating a roof side structure as a comparative example. As shown in FIG. 7, in the roof side structure 14 as a comparative example, the roof side rear reinforcement 16 has an inclined surface 56a so that the outside is lowered below the horizontal from the vehicle body mounting surface 54a fixed to the roof side inner panel 24. Was stretched. The inclined surface 56 a is connected to the protruding surface 58. The projecting surface 58 was supported by the inclined surface 56a and an upstanding surface 56b that erected almost vertically from the vehicle body mounting surface 54b. However, even if the roof side rear reinforcement 16 is provided, further improvement in rigidity has been desired.

  Therefore, as shown in FIG. 4, the roof side structure 114 of the present embodiment has the above-described hat-shaped cross section. According to the hat shape, the projecting surface 158 parallel to the roof side inner panel 124 is supported by the two standing surfaces 156 a and 156 b that stand substantially perpendicular to the roof side inner panel 124. On the other hand, in the roof side structure 14 of the comparative example, among the surfaces that support the protruding surface 58, there is only one upstanding surface 56b that is perpendicular to the roof side inner panel 24 and can be improved in rigidity. Thereby, in this embodiment, rigidity higher than a comparative example can be obtained. Further, since the area of the cross section of the roof side rear reinforcement 116 is larger than that of the comparative example, the deformation amount of the roof side rear reinforcement 116 can be secured, and it is possible to contribute to the improvement of load absorption of the vehicle body.

  However, when a hat-shaped cross section is formed as described above, electrodeposition is performed on the outer corner portion 160a of the vehicle body mounting surface 154a and the standing surface 156a, and the inner corner portion 160b of the vehicle body mounting surface 154b and the standing surface 156b. It is necessary to prevent liquid and cleaning liquid from accumulating. Therefore, as shown in FIG. 3, in the present embodiment, the roof side rear reinforcement 142 is installed so that the two standing surfaces 156a and 156b descend toward the rear of the vehicle body with respect to the horizontal plane. Thereby, since the undercoat electrodeposition liquid and the cleaning liquid at the time of production are discharged along this downward movement, there is no possibility that the electrodeposition liquid and the cleaning liquid accumulate in the corner portions 160a and 160b.

  As described above, the reason that the roof side rear reinforcement 116 needs to be lowered toward the rear of the vehicle body is that the roof side inner panel 124 is normally provided horizontally in a hatchback vehicle or the like that forms a box-shaped cabin space. It is. This is because when the roof side rear reinforcement is attached along the horizontal roof side inner panel, the electrodeposition liquid and the cleaning liquid accumulated at the corners cannot be discharged.

  In order to discharge the electrodeposition liquid and the cleaning liquid, it is conceivable to form a drain hole. However, the formation of the hole for draining reduces the rigidity of the vehicle body, which is contrary to the improvement in the rigidity of the vehicle body, which is the original purpose.

  FIG. 5 is a diagram showing a first modification of the roof side rear reinforcement of FIG. As shown in FIG. 5, as other roof side rear reinforcement 117, bead 162 extending in the vehicle body front-rear direction may be provided on vehicle body attachment surfaces 154a, 154b, standing surfaces 156a, 156b, and projecting surface 158, respectively. By providing such a bead 162, the surface rigidity of each surface can be improved. In FIG. 5, one bead 162 is represented by a symbol as a representative.

  When the bead 162 is provided, there is a possibility that the electrodeposition liquid or the cleaning liquid may accumulate on the inclined surface of the bead 162. Accordingly, the slope of the inclined surface of the bead 162 and the degree of the downward movement of the roof side rear reinforcement 117 toward the rear of the vehicle body may be set so that the electrodeposition liquid and the cleaning liquid can be reliably discharged.

  Again, a description will be given with reference to FIG. In the present embodiment, the center line of the roof side rear reinforcement 116 forms an angle with respect to the roof side inner panel 124. That is, the center line of the roof side rear reinforcement 116 is installed so as to descend toward the rear of the vehicle body with respect to the roof side inner panel 124. Thus, since the center line of the roof side rear reinforcement 116 has a vector in the vertical direction as well as the front and rear direction, the rigidity of the roof side inner panel 124 can be improved with respect to the vertical load X inputted from the upper part of the vehicle body. it can. By improving the rigidity, even when the load X is applied, the load can be distributed to each part of the vehicle body, and deformation of the passenger compartment can be avoided. That is, it is possible to improve the rigidity of the roof side inner panel 124 with respect to the load X and contribute to the improvement of the load absorption of the vehicle body.

  FIG. 6 is a view showing a second modification of the roof side rear reinforcement of FIG. As shown in FIG. 6, the roof side rear reinforcement 118 as the second modified example is descended on the rear side of the vehicle body (in an arc shape) along a curved locus that is convex upward. As a result, the upwardly convex curved portion has an effect of improving the rigidity against the load applied to the roof side from above, so that the roof side inner panel 124 is subjected to the vertical load X input from the upper part of the vehicle body as described above. It is possible to improve rigidity and contribute to improvement of load absorption of the vehicle body.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings. According to the roof side structure 114 according to the present embodiment, the rigidity of the upper portion of the vehicle body can be increased with respect to the load applied to the vehicle body in the vertical direction. By ensuring the rigidity of the vehicle body side portion or the vehicle body lower portion by the pillar portion and the side sill portion, it is possible to produce a further synergistic effect. Thereby, high rigidity is securable.

  Needless to say, the present invention is not limited to such examples. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  The present invention can be used for a roof side structure of a vehicle body.
