Japanese Patent Application Laid-Open No. 59-029571

  In the high roof mounting structure of Patent Document 1, the inner surface of the roof side panel is designed to suppress collapse of the roof in the vertical direction when the input load is increased from the ceiling surface of the roof to the cabin side due to the vehicle reversing due to a vehicle accident or the like. It is possible to fix the reinforcement to the body side via the bracket by fixing the reinforcement extending vertically to the body and fixing the bracket to the body side (side rail) and fastening the bracket and the reinforcement. . Thereby, the load from the ceiling surface can be transmitted to the body side.

  However, in a structure in which reinforcement is fixed to the body side via a bracket, the mounting error of the high roof causes misalignment between the bolt hole of the bracket and the other (for example, reinforcement) bolt hole. It may not be possible. Such a disadvantage can be eliminated by using a low-rigidity bracket and deforming the bracket to absorb errors. However, if a low rigidity bracket is used, the increase in load may damage the bracket and the reinforcement may not function effectively. As described above, it is difficult to achieve both the improvement of the assembling performance of the high roof and the suppression of the crushing deformation.

  Then, an object of the present invention is to provide a high roof attachment structure of a vehicle that can achieve both improvement in assembling workability and suppression of crushing deformation.

  In order to achieve the above object, a high roof mounting structure of a vehicle according to a first aspect of the present invention has a ceiling surface and a pair of left and right roof side surfaces. The ceiling surface section defines the upper side of the cabin. The pair of left and right roof side portions extend downward from both side edges in the vehicle width direction of the ceiling surface portion. Lower portions of the left and right roof side portions are fixed to a pair of left and right body sides extending in the front and rear direction at upper portions on both sides in the vehicle width direction of the cabin.

On the inner surface of the roof side surface portion, a reinforcement is fixed which forms a closed cross section extending in the vertical direction between the roof side surface portion and the roof side surface portion. The reinforcement is not fixed to the body side, and the body side is provided with a reinforcement receiving surface which intersects the vertical direction and faces the end face of the reinforcement. The end face of the reinforcement approaches or contacts the reinforcement receiving surface. The reinforcement receiving surface has a reinforcement movement restricting portion which protrudes upward and is accommodated in the closed cross section. The reinforcement movement restricting part restricts the movement of the end surface of the reinforcement on the reinforcement receiving surface when the end surface of the reinforcement abuts on the reinforcement receiving surface.

  In the above configuration, when the vehicle reverses due to a vehicle accident or the like and the input load from the ceiling surface to the compartment increases, the end face of the reinforcement contacts the reinforcement receiving surface, and the load from the ceiling surface receives the reinforcement It is transmitted to the body side through the face. Therefore, reinforcement can be made to function effectively, and crushing deformation of the high roof can be reliably suppressed.

  In addition, since the reinforcement is not fixed to the body side through the bracket or the like, the assembling performance of the high roof is improved.

Further , since the fall of the reinforcement is prevented by the reinforcement movement restricting portion, the load from the ceiling surface portion can be more reliably transmitted to the body side.

  According to the high roof mounting structure of a vehicle of the present invention, it is possible to achieve both improvement in assembling workability and suppression of crushing deformation.

  As shown in FIG. 1, a pair of left and right body sides 4 forming both sides (left and right sides) of the passenger compartment 2 in the vehicle width direction are respectively constituted of a side panel outer 5 and a side panel inner 6 outside the vehicle width direction. Ru. The upper end portion of the side panel outer 5 is bent inward in the vehicle width direction and fixed to the upper end portion of the side panel inner 6 to form a closed cross section 20 extending in the front-rear direction with the side panel inner 6. An outer rail 7 extending in the front-rear direction on the outer side in the vehicle width direction of the side panel outer 5 is fixed to the upper end outer side surface portion 24 of the side panel outer 5 that divides the outer side in the vehicle width direction of the closed cross section 20.

  The high roof 3 has a ceiling surface 9 that defines the upper side of the passenger compartment 2 and a pair of left and right roof side surfaces 10 that extend downward from both side edges of the ceiling surface 9 in the vehicle width direction. The end edge 9a on the outer side in the vehicle width direction of the ceiling surface 9 and the upper end edge 10a of the roof side surface 10 are vertically stacked and fixed. A rail contact portion 19 is formed at the lower end portion of the roof side surface portion 10 to be bent outward in the vehicle width direction, and the high roof 3 is mounted on the body side 4 by mounting the rail contact portion 19 on the outer rail 7 and fixing. The roof side surface portion 10 is erected and extended from the body side 4 (body side upper surface portion 25 described later). In the case of a roof having a standard vehicle height, a ceiling surface (not shown) is fixed to the body side upper surface 25.

  As shown in FIGS. 3 and 4, reinforcements 11 extending in the vehicle width direction are fixed to the front and rear sides of the inner surface (lower surface) of the ceiling surface 9 by an adhesive. Each of the front and rear (total 2) reinforcements 11 is made of a metal plate bent in a channel shape in cross section, and a rectangular closed cross section (in the vehicle width direction) extending between the ceiling surface 9 and the inner surface Space) 21 is formed.

  On each of the front and rear sides of the inner surface of each roof side surface portion 10, a reinforcement 12 extending in the vertical direction is fixed by an adhesive. Each of the front, rear, left and right (total four) reinforcements 12 is configured with one part. Each reinforcement 12 is made of a metal plate bent in a cross-sectional channel shape, and forms a rectangular closed cross section (space) 22 extending in the vertical direction between the reinforcement 12 and the inner surface of the roof side surface portion 10. The upper end portion of each reinforcement 12 is fixed to the inner surface of the ceiling surface 9.

  Between the reinforcement 11 fixed to the ceiling surface portion 9 and the reinforcement 12 fixed to the roof side surface portion 10, a connecting member 13 connecting the reinforcements 11 and 12 with each other is provided. Each of the front, rear, left and right (total four) connecting members 13 is made of a metal plate bent in a channel shape in cross section, and the inner surface of the ceiling surface 9 and the joint surface between the ceiling surface 9 and the roof side surface 10 are A rectangular closed cross section (space) 23 extending in the vehicle width direction is formed between the roof side surface portion 10 and the inner surface. The closed cross sections 21 and 22 formed by the reinforcements 11 and 12 are continuous through the closed cross section 23 formed by the connecting member 13. The end in the vehicle width direction outside of each connecting member 13 is fastened and fixed to the reinforcement 12 by a bolt 14 and a nut 15.

  As shown in FIG. 1, the upper surface portion (body-side upper surface portion) 25 of the side panel outer 5 partitioning the upper side of the closed cross section 20 extends in the front-rear direction intersecting the vertical direction. A reinforcement receiving member 8 made of a metal plate is fixed to the lower body side upper surface portion 25 of the reinforcement 12 fixed to the high roof 3. The upper surface of the reinforcement receiving member 8 fixed to the body side upper surface portion 25 intersects the vertical direction to configure a reinforcement receiving surface 8 a facing the lower end surface 12 a of the reinforcement 12. The lower end surface 12a of the reinforcement 12 (see FIG. 2) approaches or contacts the reinforcement receiving surface 8a.

  As shown in FIGS. 5 and 6, in the reinforcement receiving member 8, a flat plate-like fixing portion 16 and a movement of reinforcement that protrudes (bulges) upward from the fixing portion 16 at an intermediate portion of the reinforcement receiving member 8. The restricting portion 17 and the peripheral rib 26 bent upward from the end edge in the vehicle width direction of the fixing portion 16 to enhance the rigidity of the reinforcement receiving member 8 are integrally formed by press processing.

  Round holes 16 a and long holes 16 b are formed in the fixing portion 16 as bolt holes. The reinforcement receiving member 8 is fastened and fixed to the side panel outer 5 of the body side 4 by bolts 18 inserted through each of the round hole 16 a and the long hole 16 b. In addition, since one of the bolt holes is the long hole 16b, the assembly error can be absorbed.

When it abuts on the receiving surface 8a, the movement of the reinforcement 12 in the direction (front and rear direction and left and right direction) intersecting the vertical direction is restricted.

  According to the present embodiment, when the vehicle reverses due to a vehicle accident or the like and the input load from the ceiling surface 9 to the compartment 2 increases, the lower end surface 12a of the reinforcement 12 abuts on the reinforcement receiving surface 8a, The load from the ceiling surface 9 is transmitted to the body side 4 via the reinforcement receiving surface 8a. Therefore, the reinforcement 12 can be functioned effectively, and the crushing deformation of the high roof 3 can be reliably suppressed.

  Further, since the reinforcement 12 is not fixed to the side of the body side 4 via a bracket or the like, the assembling workability of the high roof 3 is improved.

  Furthermore, since the fall of the reinforcement 12 is prevented by the reinforcement movement restricting part 17, the load from the ceiling surface part 9 can be more reliably transmitted to the body side 4.
