    [0004] However, in such a vehicle rear upper structure, when a load directed to the top of the vehicle is transmitted from a suspension, which supports a rear wheel to a suspension tower, the vehicle body undergoes torsional deformation. In this case, the junction between the outside of the roof and the tensioners, and the junction between the outside of the roof and the upper rear side panel can be deformed, which tends to separate them. SUMMARY OF THE INVENTION
    [0005] The present invention has been provided in view of the problems described above, and provides a rear structure of the vehicle body that prevents the joint between the outer roof side and an upper rear cross-sectional portion and the joint between the outer side of ceiling and support tray suffer a deformation, which tends to separate them.
    [0006] According to one aspect of the present invention, there is provided a rear body structure for a vehicle, including a wheel housing that is located on one side at the rear of a vehicle that houses a rear wheel; a suspension tower plate coupled to the wheel housing and supporting an upper end portion of a suspension supporting the rear wheel; an upper rear cross-sectional portion which is located within an extended portion which extends towards the top of the vehicle from the wheel housing in the direction of the width of the vehicle, and forms a skeleton, which is elongated in the direction of the width of the vehicle. vehicle; a support tray that is located within the vehicle-width-directed extending portion and the vehicle rear of the upper rear cross-sectional portion, and has a front end portion, which is connected to the upper rear cross-sectional portion; an inner roof side that is located at the top of the vehicle in the extended portion, and has a lower end portion that is connected to an upper end portion of the extended portion; an outer side of the roof which is located outside the extended portion and the inner side of the roof in the widthwise direction of the vehicle which has a lower end portion which is connected to the wheel housing, a front end portion which is connected to the portion of upper rear cross section, and a rear end portion which is attached to the support tray; and a blanque (bulk) that couples the outer side of the roof and upper rear cross-section portion.
    [0007] According to the rear structure of the vehicle body, the outer side of the roof and the upper rear cross-section portion are coupled by the white. Thus, even when a load directed to the top of the vehicle is transmitted from a suspension supporting a rear wheel to a suspension tower and the vehicle body undergoes torsional deformation, the upper rear cross-sectional portion is prevented from being moved to inward in the direction of the vehicle's width. This prevents the joint between the outside of the roof and the rear upper cross-sectional portion and the joint between the outside of the roof and the vehicle's rear body structure from deforming, which tends to separate them.
    [0008] Especially, because the outer roof side and the upper rear cross-section portion are coupled by the blank (150), the junction between the outer roof side and the upper rear cross-section portion does not undergo deformation, which tends to to separate them more effectively.
    [0009] In the rear structure of the vehicle body, a blanket couples the outer side of the roof to at least one of the extended portion and the inner side of the roof at a location located between a joint that is located between the front end portion and the roof portion. rear end of the outer side of the roof, where the blanket and the upper rear cross-sectional portion are joined, and a joint where the rear end portion of the outer side of the roof and the support tray are joined.
    [00010] According to the rear vehicle body structure, the outer side of the roof and at least one of the extended portion and the inner side of the roof are coupled by the blanket at a location located near the junction, where the rear end portion of the the outer side of the ceiling and the support tray are linked. This also prevents the junction between the outside of the roof and the support tray from deforming, which tends to separate them more effectively.
    [00011] In the rear structure of the vehicle body, the outer side of the roof may have a front wall portion and a rear wall portion that are arranged in the direction of the length of the vehicle, and a connecting wall portion, which couples the portion of front wall and the rear wall portion. The blanket may have a front coupling portion which is connected to the front wall portion, a rear coupling portion which is connected to the rear wall portion, and an inner coupling portion which is connected to the connecting wall portion, and a portion of internal coupling, which has a front portion which is connected to the upper rear cross-sectional frame portion and a rear portion which is connected to at least one of the extended portion and inner side of the roof.
    [00012] According to the rear structure of the vehicle body, when a load directed to the top of the vehicle is transmitted from a suspension that supports a rear wheel to a suspension tower, and the vehicle body undergoes torsional deformation, a shear load acts at the junction between the outside roof front wall portion and the blanket front coupling portion, and the junction between the outside roof rear wall portion and the blanket rear coupling portion. Thus, the load, which tends to separate the joint between the outside of the roof and the upper rear cross-sectional portion and the joint between the outside of the roof and the support tray, can be reduced. This prevents the deformation of the joints, which tends to separate them more effectively.
    [00013] In the rear structure of the vehicle body, the front coupling portion and the rear coupling portion may extend in opposite directions along the height direction of the vehicle. The outer coupling portion and the inner coupling portion may extend in opposite directions along the height direction of the vehicle.
    [00014] According to the rear structure of the vehicle body, the front wall portion and the rear wall portion extend in opposite directions along the height direction of the vehicle. Thus, the spot welding gun is prevented from interfering with the front coupling portion when the front wall portion and the front coupling portion are joined by spot welding. In addition, the spot welding gun is prevented from interfering with the front coupling portion when the rear wall portion and the rear coupling portion are joined by spot welding.
    [00015] Similarly, the outer coupling portion and the inner coupling portion extend in opposite directions along the height direction of the vehicle. Thus, the spot welding gun is prevented from interfering with the internal coupling portion, when the connecting wall portion 136 and the external coupling portion are connected by spot welding, and the spot welding gun is prevented from interfering with the outer coupling portion, when the upper rear cross-sectional portion of at least one of the extended portion and outer side of the roof which is connected to the coupling portion by spot welding. This increases the efficiency of spot welding processes.
    [00016] In the rear structure of the vehicle body, the front coupling portion, the rear coupling portion, the external coupling portion, and the internal coupling portion may all extend towards the base of the vehicle, and be connected together to form an annular configuration.
    [00017] According to the vehicle body rear structure, the coupling portions of the blanket are connected together to form an annular configuration. This configuration can increase the stiffness of the blanket and allow the reduction of the thickness of the blanket.
    [00018] In the rear frame of the vehicle body, the coupling coupling portion may have an opening, which may be either a groove or a hole, and at least one of the weld points through which the extended portion and the section portion rear transverse are connected by spot welding, can be a spot weld, formed by spot welding through the opening.
    [00019] According to the rear structure of the vehicle body, the number of weld points between the extended portion and the upper rear cross-sectional portion can be increased, because the extended portion and upper rear cross-sectional portion are connected by spot welding through the opening of the internal coupling portion. This improves the strength of the coupling between the extended portion and the upper rear cross-sectional portion.
    [00020] In the vehicle body rear structure, the front end portion and the rear end portion of the outer side of the roof may be connected to the inner side of the roof, and the outer side of the roof may have an upper end portion that it is located on the base side of the vehicle compared to the upper end portion of the inner roof side, and is not connected to the upper end portion of the inner roof side.
    [00021] According to the rear structure of the vehicle body, the upper end portion on the outer side of the roof that is located on the base side of the vehicle, compared to the upper end portion of the inner side of the roof, and not being attached to the upper end portion of the inner side of the roof. Thus, when a load directed to the top of the vehicle is transmitted from a suspension that supports the rear wheel to the suspension tower, and the vehicle body undergoes torsional deformation, and when the inner side of the roof undergoes torsional deformation that tends to displace the upper end portion thereof outwards in the vehicle width direction, the torsional deformation of the inner side of the roof is prevented from being transmitted to the upper rear cross-section portion via the outer side of the roof. This prevents the joint between the outside of the roof and the upper rear cross-sectional portion and the joint between the outside of the roof and the support tray from deforming, which tends to separate them more effectively.
    [00022] As described in detail above, according to the invention, the joint between the outer side of the roof and the upper rear cross-sectional portion and the joint between the outer side of the roof and the support tray are prevented from suffering a deformation , which tends to separate them.

    [00061] As shown in Figure 8, the outer side of the roof 130 has an upper end portion 130D which is located on the base side of the vehicle compared to the upper end portion 110C of the inner side of the roof 110. upper end 130D of the outer side of the roof 130 is disposed outwardly in the widthwise direction of the vehicle from the inner side of the roof 110 and is not connected to the upper end portion 110C of the inner side of the roof 110.
    [00062] The functions and effects of the configuration of the present invention will be described below. A comparative example will first be described to clarify more fully the functions and effects of the embodiment of the present invention.
    [00063] A vehicle rear body structure 210, according to the comparative example shown in Figure 10, has a different configuration from the vehicle rear body structure 10 according to the configuration of the present invention described below. In the comparative example, components having the same name as the configuration of the present invention will be given the same reference numerals for reasons of convenience.
    [00064] The rear body structure of vehicle 210, according to comparative example, is not provided with blanque 150 (see Figure 6 and so on). In addition, the upper end portion 13D of the outer side of the roof 130 further extends to the top of the vehicle and being connected to the upper end portion 110C of the inner side of the roof 110 by spot welding at the solder points 188.
    [00065] However, in the vehicle rear body structure 210 according to the comparative example, when a load directed to the top of the vehicle is transmitted from a suspension supporting the rear wheel to the suspension tower plate 30, the The vehicle bodywork undergoes torsional deformation, and the upper rear cross-sectional portion 160 (with reference to the upper rear cross-sectional portion 180 (see Figure 1)) is retracted in the width direction of the vehicle. Thus, the solder points 174 connecting the outer side of the roof 130 and the upper rear cross-sectional portion 160, and the solder point 17 connecting the outer side of the roof 130 and the support tray 100, undergo a deformation, which tends to separate them.
    [00066] Especially, when the body undergoes a torsional deformation, as described above, the inner side of the roof 110 undergoes a torsional deformation that tends to displace the upper end portion 110C upwards in the direction of the vehicle's width, and the portion of upper end 130D of the outer side of the roof 130 is taken out of the vehicle by the upper end portion 110C of the inner side of the roof 110. Thus, the solder points 174 and 177 and solder points around them undergo a large deformation, which tends to to separate them.
    [00067] In contrast, in the rear structure of the vehicle body 10, according to an embodiment of the present invention, shown in Figures 1 to 8, the outer side of the roof 130 and the upper rear cross-section portion 160 are coupled by the white. 150. Thus, even when a load directed towards the top of the vehicle is transmitted from a suspension supporting the rear wheel to the suspension tower plate 30 and the vehicle body undergoes torsional deformation, the upper rear cross-sectional portion 160 is prevented from being brought in towards the width of the vehicle. This prevents weld points 174 and 177 and the weld points around them from deforming, which tends to separate them.
    [00068] In addition, the outer side of the roof 130 and the flange 166 of the upper rear cross-section portion 160 are directly coupled by the blanket 150. In addition, the outer side of the roof 130 and the extended portion 26 and the inner side of the roof 110 are coupled by blank 150 at a location closer to the joint (soldering point 177) where the rear end portion 30C of the outer side of the roof 13 and the support tray 100 are connected. This prevents weld points 174 and 177 and the weld points around them from deforming, which tends to separate them more effectively.
    [00069] When a load directed to the top of the vehicle is transmitted from a suspension supporting a rear wheel to the suspension tower plate 30 and the vehicle body undergoes torsional deformation, a shear load acts on the weld point 181, where the front wall portion 132 and the front coupling portion 134 and the rear coupling portion are connected. Thus, the load that tends to separate the solder points 174 and 177 and the solder points around them can be reduced. This prevents weld points 174 and 177 and the points around them from deforming, which tends to separate them more effectively.
    [00070] In addition, the front wall portion 132 and the rear wall portion 134 extend in opposite directions along the height direction of the vehicle. Thus, the spot welding gun is prevented from interfering with the rear coupling portion 154 when the front wall portion 132 and the front coupling portion 152 are connected by spot welding and the spot welding gun is prevented from interfere with the front coupling portion 152 when the rear wall portion 134 and the rear coupling portion 154 are spot welded.
    [00071] Similarly, the outer coupling portion 156 and the inner coupling portion 158 extend in opposite directions along the height direction of the vehicle. Thus, the spot welding gun is prevented from interfering with the internal coupling portion 158, when the connecting wall portion 136 and the external coupling portion 156 are connected by spot welding, and the welding gun is prevented from interfering with the outer coupling portion 156, when the upper rear cross-sectional portion 160, the extended portion 26, and the inner side of the roof 110 are joined to the inner coupling portion 158 by soldering. This improves the efficiency of the welding process operation.
    [00072] In addition, the number of weld points between the upper rear cross-sectional portion 160 and the extended portion 26 is increased because the flange 166 of the upper rear cross-section portion 160 and the extended portion 26 are welded together to point (through the solder point 171A) through the opening 159 of the internal coupling portion 158. This avoids the coupling tension between the upper rear cross-sectional portion 160 and the extended portion 26.
    [00073] In addition, the upper end portion 130D of the outer side of the roof 130 is located on the base side of the vehicle compared to the upper end portion 110C of the inner side of the roof 110 and not being connected to the upper end portion 110C from the inner side of the roof 110. Thus, when a load directed towards the top of the vehicle is transmitted from a suspension supporting the rear wheel to the suspension tower plate, the bodywork undergoes torsional deformation and when the inner side of the roof 110 undergoes a torsional deformation which tends to displace its upper end portion 110C outwards towards the width of the vehicle, the torsional deformation of the inner side of the roof 110 is prevented from being transmitted to the upper rear cross-section portion 160 through the side. external roof 130. This prevents the weld points 174 177 and the weld points around them from deforming, which tends to separate them more effectively.
    [00074] The blanket 150 can be configured as shown in Figure 9. In other words, in a modification shown in Figure 9, the front coupling portion 152, the rear coupling portion 154, the outer coupling portion 156, and the portion of internal coupling 158 all of which extend towards the base of the vehicle, and are connected together to form an annular configuration. This configuration improves the rigidity of the blank 150 and allows to reduce the thickness of the blank 150.
    [00075] Although an embodiment of the present invention has been described, it should be appreciated that the present invention is not limited to the described description, and may be implemented with various modifications within the intended scope.
    [00076] Technical ideas, which can be understood from the configuration in addition to the present invention, contained in the appended claims, will be described below along with their effects.
    [00077] In other words, the rear structure of the vehicle body includes a wheel housing located on one side of a vehicle and housing a rear wheel; a suspension tower plate that is coupled to the wheel housing and supports an upper end portion of a suspension that supports the rear wheel; an upper rear cross-sectional portion that is located in an extended portion, which extends towards the top of the vehicle from the wheel housing in the widthwise direction of the vehicle; a support tray that is located in the portion extending across the width of the vehicle and forms a skeleton that is elongated across the width of the vehicle; a support tray that is located on the vehicle-width-directed extending portion and on the vehicle rear side of the upper rear cross-sectional portion and has a front end portion that is connected to the upper rear cross-sectional portion; an inner side of the roof which is located at the top of the vehicle of the extended portion and having a lower end portion which is connected to the upper end portion of the extended portion; an outer side of the roof which is located outside the extended portion and inner side of the roof in the width width direction and having a lower end portion which is connected to the wheel housing, a front end portion which is connected to the section portion upper rear transverse and inner side of the roof, and a rear end portion which is connected to the support tray and inner side of the roof and an upper end portion which is located on the base side of the vehicle compared to the upper end portion of the inner side of the roof and not being connected to the upper end portion of the inner side of the roof.
    [00078] According to the rear structure of the vehicle body, the upper end portion is located on the base side of the vehicle compared to the upper end portion of the inner side of the roof, and not being connected to the upper end portion from the inner side of the ceiling. Thus, when a load directed to the top of the vehicle is transmitted from a suspension that supports a rear wheel to the suspension tower, the vehicle body undergoes torsional deformation and when the inner side of the roof undergoes torsional deformation, which tends to shift the upper end portion outwards towards the width of the vehicle, the torsional deformation of the inner side of the roof is prevented from being transmitted to the upper rear cross-section portion in the direction of the width of the vehicle, the torsional deformation of the inner side of the roof is prevented from being transmitted to the upper rear cross-section portion via the outside of the roof. This prevents the joint (177) between the outside of the roof and the upper rear cross-sectional portion and the joint (177) between the outside of the roof and the support tray from deforming, which tends to separate them.
