[0006] The problem to be solved by the utility model

[0007] In recent years, components such as baffles, spring supports, lower inner panels of front pillars, and transverse members of the front wall of the carriage have sometimes been integrally formed by die casting. Metal plate components such as the front bulkhead, front wall of the carriage, and upper front pillars are modularized by mounting them onto a front casting, which is such a die-cast product. In such a structure, sealing between the front casting and the front bulkhead and front wall of the carriage after modularization is quite difficult.

[0008] In view of the above-mentioned facts, the purpose of this utility model is to obtain a vehicle side structure that can seal the front casting, front bulkhead and front wall of the carriage after modularization.

[0009] Methods for solving problems

[0010] The first embodiment of the vehicle side structure comprises: a front casting integrally having a pair of left and right front pillar lower inner panels and a front wall transverse member; a front wall of the vehicle body disposed between the left and right front pillar lower inner panels and joined to the front wall transverse member; a front bulkhead joined to the upper end of the front wall of the vehicle body; a bracket disposed between the left and right front pillar lower inner panels and the front bulkhead and joined to the front wall of the vehicle body and the front bulkhead; and a sealing material applied between the bracket and the left and right front pillar lower inner panels, between the bracket and the front wall of the vehicle body, and between the bracket and the front bulkhead.

[0011] According to the first embodiment, the front casting integrally comprises a pair of lower inner panels for the left and right front pillars and a transverse member for the front wall of the carriage. A front wall of the carriage is disposed between the lower inner panels for the left and right front pillars. The front wall of the carriage is joined to the transverse member for the front wall of the carriage, and a front bulkhead is joined to the upper end of the front wall of the carriage. A bracket is disposed between the lower inner panels for the left and right front pillars and the front bulkhead. The bracket is joined to the front wall of the carriage and the front bulkhead. A sealing material is applied between the bracket and the lower inner panel for the left and right front pillars, between the bracket and the front wall of the carriage, and between the bracket and the front bulkhead. According to this embodiment, even after the front wall of the carriage, the front bulkhead, and the bracket are modularly mounted onto the front casting, a seal can be achieved between the front casting, the front bulkhead, and the front wall of the carriage by applying the aforementioned sealing material.

[0012] Utility Model Effect

[0013] As explained above, in the vehicle side structure involved in this utility model, the front casting and the front bulkhead and the front wall of the vehicle body can be sealed after modularization. Attached Figure Description

[0018] Figure 5 To indicate and Figure 3 A sectional view of the section corresponding to line F5-F5. Detailed Implementation

[0019] The following is for reference Figures 1 to 5 The vehicle side structure 10 according to one embodiment of this utility model will be described. In addition, the arrows FR, UP, and RH appropriately shown in the figures represent the forward (traveling direction), upward, and rightward directions of the vehicle with the vehicle side structure 10 applied, respectively. Hereinafter, in the description using only the forward / backward, left / right, and up / down directions, we will use "forward / backward" to represent the forward / backward direction, "left / right" to represent the left / right direction, and "up / down" to represent the up / down direction.

[0020] exist Figure 1The right side portion of the vehicle side structure 10 is shown in a perspective view. The vehicle side structure 10 includes a front casting 12, a front wall 20 of the carriage, a front bulkhead 22, and a bracket 24, and is configured to be symmetrical from left to right.

[0021] The front casting 12 is a component formed by die casting, for example, aluminum alloy, and integrally includes a pair of left and right front pillar lower inner panel portions 14 (the left front pillar lower inner panel portion 14 is not shown in the figure), a pair of left and right baffle member portions 16 (the left baffle member portion 16 is not shown in the figure), and a front wall transverse member portion 18 of the carriage.

[0022] The lower inner panel 14 of the front pillar extends vertically along the side of the vehicle. A lower outer panel of the front pillar, for example made of steel, is joined to the outer side of the lower inner panel 14 in the left-right direction (outer side in the vehicle width direction), thus forming the lower part of the front pillar. A baffle member 16 extends integrally forward from the upper part of the lower inner panel 14 of the front pillar. A front fender panel, for example made of steel, is joined to the outer side of the baffle member 16 in the left-right direction. A transverse member 18 of the front wall of the passenger compartment is integrally mounted between the lower ends of the lower inner panels 14 of the left and right front pillars and extends in the left-right direction.

[0023] A front wall 20 is disposed between the lower inner panel portions 14 of the left and right front pillars. The front wall 20 is made of steel plate, for example, and is disposed on the rear side of the transverse member portion 18 of the front wall, with the front-to-back direction set in the plate thickness direction. The front surface of the lower end of the front wall 20 is bonded to the rear surface of the upper end of the transverse member portion 18 of the front wall using a structural adhesive 28.

[0024] On the front surface of the upper end of the front wall 20 of the carriage, a front bulkhead 22 is joined using the aforementioned structural adhesive 28. The front bulkhead 22 is made of, for example, steel plate and integrally has a rear wall portion 22A whose lower end is joined to the upper end of the front wall 20 of the carriage, and an upper wall portion 22B extending from the upper end of the rear wall portion 22A toward the front and downward sides. Flange portions 22C are provided at both ends of the front bulkhead 22 in the left and right directions, with the left and right directions being the plate thickness direction. The flange portions 22C extend integrally from the rear wall portion 22A and the upper wall portion 22B.

[0025] A bracket 24 is disposed between the lower inner panel 14 of the front pillar and the front bulkhead 22. The bracket 24 is, for example, constructed of steel plate. Figure 2As shown, the bracket 24 integrally includes a side wall portion 24A with the left-right direction defined as the plate thickness direction, an upper wall portion 24B extending from the upper end of the side wall portion 24A toward the center side in the left-right direction (inner side in the vehicle width direction), and a rear wall portion 24C extending from the rear end of the side wall portion 24A toward the center side in the left-right direction. The rear portion and the middle portion in the front-rear direction of the upper wall portion 24B are inclined in a downward slope toward the front side, and the slope is larger at the middle portion in the front-rear direction of the upper wall portion 24B compared to the rear portion of the upper wall portion 24B.

[0026] like Figure 1 As shown, the front end of the upper part of the front pillar 26 is disposed above the bracket 24 and the lower inner plate part of the front pillar 14. The upper part of the front pillar 26 is made of steel plate, for example, and the lower surface of the front end is joined to the upper surface of the upper wall part 24B of the bracket and the upper surface of the lower inner plate part of the front pillar 14.

[0027] like Figures 3 to 5 As shown, the rear surface of the rear wall portion 24C of the bracket 24 is bonded to the front surface of the outer end in the left-right direction of the front wall 20 using structural adhesive 28. The bracket 24 protrudes upwards compared to the front wall 20 of the carriage. Figure 3 As shown, the lower surface of the upper wall portion 24B of the bracket 24 is bonded to the upper surface of the upper wall portion 22B of the front bulkhead 22 using structural adhesive 30.

[0028] like Figure 3 as well as Figure 4 As shown, a sealing material 32, such as an adhesive, is applied between the side wall portion 24A of the bracket 24 and the flange portion 22C of the front bulkhead 22, between the upper wall portion 24B of the bracket 24 and the upper wall portion 22B of the front bulkhead 22, and between the rear wall portion 24C of the bracket 24 and the rear wall portion 22A of the front bulkhead 22. This seals the gaps between the side wall portion 24A and the flange portion 22C, between the upper wall portions 24B and 22B, and between the rear wall portions 24C and 22A. Furthermore, as... Figure 4 As shown, on the rear wall portion 22A of the front bulkhead 22, at the location opposite to the rear wall portion 24C of the bracket 24, a stepped portion 22A1 is formed that curves forward in a stepped manner. Figure 1 (Illustration omitted).

[0029] In addition, such as Figure 1 , Figures 3 to 5 As shown, a sealing material 34, such as an adhesive, is applied between the side wall portion 24A of the bracket 24 and the lower inner panel portion 14 of the front pillar, and between the rear wall portion 24C of the bracket 24 and the transverse member portion 18 of the front wall of the carriage. This seals the gaps between the side wall portion 24A and the lower inner panel portion 14 of the front pillar, and between the rear wall portion 24C and the transverse member portion 18 of the front wall of the carriage. Furthermore, as... Figure 1 As shown, the aforementioned sealing material 34 is also applied between the upper part 26 of the front pillar and the lower inner panel 14 of the front pillar, and between the upper part 26 of the front pillar and the upper wall 24C. Furthermore, as... Figure 3 As shown, on the lower end of the rear wall portion 24C of the bracket 24, at a location opposite to the upper end of the transverse member portion 18 of the front wall of the carriage, a stepped portion 24C1 is formed that curves forward in a stepped manner. Figure 1 (Illustration omitted).

[0030] In the vehicle side structure 10 described above, the front casting 12 integrally comprises a pair of lower inner panels 14 for the left and right front pillars and a transverse member 18 for the front wall of the passenger compartment. A front wall 20 is disposed between the lower inner panels 14 for the left and right front pillars. The front wall 20 is joined to the transverse member 18 for the front wall of the passenger compartment, and a front bulkhead 22 is joined to the upper end of the front wall 20. A bracket 24 is disposed between the lower inner panels 14 for the left and right front pillars and the front bulkhead 22.

[0031] The aforementioned bracket 24 is joined to the front wall 20 and the front bulkhead 22 of the carriage. Sealing materials 32 and 34 are applied between the bracket 24 and the lower inner panels 14 of the left and right front pillars, between the bracket 24 and the front wall 20 of the carriage, and between the bracket 24 and the front bulkhead 22. Therefore, because it is constructed in this way, even after the front wall 20, the front bulkhead 22, and the bracket 24 are modularly mounted onto the front casting 12, the application of the aforementioned sealing materials 32 and 34 can seal the space between the front casting 12, the front bulkhead 22, and the front wall 20 of the carriage.

[0032] While the present invention has been described above by way of example, it can be implemented in various ways without departing from its spirit. Furthermore, it is clear that the scope of the present invention is not limited to the above-described embodiments.
