Description

  The present invention prevents the occurrence of rust on the lower side portion of the vehicle body, and the vehicle body side portion for ensuring that the appearance of the vehicle body is maintained well even if rust is generated. Concerning structure.

  Conventionally, there is a vehicle body side structure of the vehicle described in Patent Document 1 below. According to this publication, the vehicle body side structure includes a rocker that forms the lower side portion of the vehicle body and extends in the front-rear direction of the vehicle body, and a vehicle body side portion structure that forms the side portion of the vehicle body and extends in the vertical direction. Includes a pillar having an outer panel made of sheet metal formed by pressing. In this case, the lower end portion of the outer panel is coupled to the outer surface of the midway portion of the rocker in the vertical direction, and this coupling is usually performed by spot welding.

  Here, the vehicle body is electrodeposition-coated at the final stage of its formation, but the outer surface of the rocker having the above structure and the lower end portion of the outer panel are coupled in a surface contact state. The paint at the time of painting is difficult to penetrate. For this reason, rust is likely to occur between the outer surface of the rocker and the lower edge of the outer panel, which reduces the appearance of the vehicle body and is not preferable.

  In addition, since the lower end edge of the outer panel is a free end when viewed in cross section and tends to be low in rigidity, the lower end edge of the outer panel is The lower end edge tends to repeatedly apply a pressure change of the pressing force to the outer surface of the rocker by vibrating to bend. Therefore, since the paint between the outer surface of the rocker and the lower edge of the outer panel tends to be peeled off by this pressing force, rust is more likely to be generated between them. There is also a possibility that abnormal noise may be generated due to the pressure change of the pressing force of the lower edge of the outer panel with respect to the side surface.

  Therefore, conventionally, a pedestal portion that protrudes outward is formed on the outer surface of the midway portion of the rocker in the vertical direction, and the midway portion in the vertical direction at the lower end portion of the outer panel is coupled to the pedestal portion, It has been proposed that a gap is formed between the outer surface of the rocker at the lower part of the rocker and the lower edge of the outer panel.

  According to the conventional technique related to the above proposal, when the vehicle body is electrodeposited, sufficient paint can be applied to the lower edge of the outer panel through the gap, and rust is generated at the lower edge. Is prevented. In addition, the presence of the gap prevents the lower edge of the outer panel from applying a pressing force to the outer surface of the rocker due to an impact force when the vehicle travels, and prevents the paint from being peeled off by the pressing force. The generation of rust is prevented and the generation of abnormal noise is prevented.

  However, as in the prior art described above, by forming a pedestal on the outer surface of the rocker, a gap is formed between the outer surface of the rocker and the lower edge of the outer panel. The lower end edge of the outer panel tends to bend more greatly due to the impact force when the vehicle travels, so that the paint applied to the lower end edge of the outer panel is peeled off. It becomes easy to do, and there exists a possibility that rust may generate | occur | produce in this lower end edge.

  On the other hand, the outer panel is usually formed by press working. At this time, the lower end edge of the outer panel is formed by shearing, and the end face of the lower end edge is left as a rough surface in a sheared state. For this reason, at the time of electrodeposition coating of the vehicle body, coating of the paint tends to be insufficient on the end surface of the lower edge portion of the outer panel. Therefore, rust is likely to be generated on the end face, which may reduce the appearance of the vehicle body.

  The present invention has been made paying attention to the above situation, and an object of the present invention is to provide a lower end edge of the outer panel when the lower end of the outer panel of the pillar is coupled to the outer surface of the rocker of the vehicle body. It is to prevent the appearance of the vehicle body from being maintained well even if the rust is generated, while preventing the occurrence of rust.

According to the first aspect of the present invention, a rocker 6 that constitutes the lower side portion of the vehicle body 2 and extends in the front-rear direction of the vehicle body 2, and a side portion of the vehicle body 2 that extends in the vertical direction and has an outer surface formed by pressing. And a pillar 20 having an outer panel 24 made of sheet metal, and a base portion 30 projecting outward is formed on the outer surface of the midway portion of the rocker 6 in the vertical direction, and the upper and lower portions at the lower end portion of the outer panel 24 are formed. A vehicle body side structure in which a gap 31 is formed between the lower surface of the rocker 6 and the lower edge 24a of the outer panel 24 while the middle part of the direction is coupled to the pedestal 30. In
The vehicle body side structure of the vehicle is characterized in that the lower end edge portion 24a of the outer panel 24 is bent toward the inside of the vehicle body 2.

  In addition, in this section, the reference numerals and drawing numbers appended to the above terms are not intended to limit the technical scope of the present invention to the “Example” section and the contents of the drawings described later.

  The effects of the present invention are as follows.

A first aspect of the present invention is a rocker that constitutes the lower side portion of the vehicle body and extends in the front-rear direction of the vehicle body, and a metal plate that constitutes the side portion of the vehicle body and extends in the vertical direction and whose outer surface is formed by pressing. A pillar having an outer panel, and a pedestal that protrudes outward is formed on the outer surface of the middle part of the rocker in the vertical direction, and the middle part in the vertical direction at the lower end of the outer panel is formed on the pedestal part. In the vehicle body side structure in which the lower part of the rocker forms a gap between the outer side of the rocker and the lower end edge of the outer panel, while being coupled,
The lower edge of the outer panel is bent toward the inside of the vehicle body.

  For this reason, since the rigidity of the lower end edge of the outer panel of the pillar is improved by bending, the lower end edge of the outer panel is elastically bent by an impact force from a running surface or the like when the vehicle is running. The vibration is suppressed. Therefore, the paint applied to the lower end edge of the outer panel is prevented from being easily peeled off by electrodeposition coating of the vehicle body, and rust is prevented from occurring at the lower end edge of the outer panel.

  Further, as described above, since the lower edge of the outer panel is bent toward the inner side of the vehicle body, the end surface of the lower edge of the outer panel is directed toward the inner side of the vehicle body. For this reason, even if the end surface of the lower edge of the outer panel is left as a rough surface in a sheared state in the press working, the coating is insufficiently applied. Since the rust is generated on the end surface of the lower edge of the outer panel directed toward the inside of the vehicle body, the rust is prevented from being easily seen from the outside of the vehicle body. Therefore, the appearance on the appearance of the vehicle body is maintained well.

  Further, as described above, when it is intended to maintain the appearance of the vehicle body well, it is allowed to leave the end surface of the lower edge of the outer panel as the rough surface in the above-described shear state. Since the processing such as the grinder finishing on the end face can be omitted, the above-described vehicle body side structure can be easily formed, which is beneficial in terms of the productivity of the vehicle body.

FIG. 3 is an enlarged cross-sectional view taken along line II in FIG. 2. 1 is an overall side view of a vehicle. FIG. 2 is a perspective development view of what is shown in FIG. 1.

  Regarding the vehicle body side structure of the vehicle according to the present invention, when the lower end portion of the outer panel of the pillar is coupled to the outer surface of the rocker of the vehicle body, while preventing the occurrence of rust at the lower end edge portion of the outer panel, In order to realize the object of maintaining the appearance of the vehicle body in good condition even when rust is generated, a mode for carrying out the present invention is as follows.

  That is, the vehicle body side structure includes a rocker that forms the lower side portion of the vehicle body and extends in the front-rear direction of the vehicle body, and a side portion of the vehicle body that extends in the up-down direction and has an outer surface formed by pressing. And a pillar having an outer panel made of sheet metal. A pedestal that protrudes outward is formed on the outer surface of the midway portion of the rocker in the vertical direction. A midway portion in the vertical direction at the lower end portion of the outer panel is coupled to the pedestal portion, while a gap is formed between the outer surface of the lower rocker and the lower edge of the outer panel. The lower end edge of the outer panel is bent toward the inside of the vehicle body.

  In order to explain the present invention in more detail, an embodiment thereof will be described with reference to the accompanying drawings.

  In the figure, reference numeral 1 denotes a vehicle exemplified by a convertible car, and an arrow Fr indicates the front in the traveling direction of the vehicle 1.

  The interior of the vehicle body 2 of the vehicle 1 is a casing 3. The vehicle body 2 includes a rocker 6 that constitutes a lower portion of the vehicle body 2 and extends in the front-rear direction of the vehicle body 2 and serves as a skeleton member of the vehicle body 2. The rocker 6 has inner and outer panels 7 and 8 that face each other in the width direction of the vehicle body 2 and are coupled to each other, and a reinforcing panel 9 that is sandwiched between the panels 7 and 8 to reinforce them. The outer panel 8 forms the outer surface of the rocker 6. The rocker 6 has sufficient rigidity because the inner, outer panels 7 and 8 and the reinforcing panel 9 make each section in the longitudinal direction a hollow closed section.

  A resin rocker cover panel 10 is provided to cover the rocker 6 from the outside. The rocker cover panel 10 is detachably attached to the rocker 6 and can be arbitrarily replaced with another specification or a new one. The rocker cover panel 10 need not be provided.

  The vehicle body 2 is installed on the rocker 6 on each of the left and right lower sides of the vehicle body 2, and constitutes a floor panel 13 that forms the lower surface of the vehicle compartment 3 and left and right side portions of the vehicle body 2. Side walls 14 that form the left and right side surfaces, and a roof panel 15 that is installed on the upper edge of each of the left and right side walls 14 to form the upper surface of the vehicle compartment 3 are provided.

  The side wall 14 is provided with a door opening 18 that allows communication between the inside and outside of the vehicle compartment 3, and a door 19 that closes the door opening 18 so as to be openable and closable. The front opening edge of the door opening 18 in the side wall 14 is a front pillar 20 that extends in the vertical direction and constitutes a skeleton member of the vehicle body 2.

  The pillar 20 has inner and outer panels 23 and 24 that face each other in the width direction of the vehicle body 2 and are coupled to each other, and a reinforcing panel 25 that is sandwiched between the panels 23 and 24 to reinforce them. The outer panel 24 forms the outer surface of the pillar 20. The pillar 20 has a sufficiently closed section with a cross section of each part in the longitudinal direction formed by the inner, outer panels 23 and 24, and the reinforcing panel 25. In this case, the inner panel 23 of the pillar 20 is formed integrally with the reinforcing panel 9 of the rocker 6. These panels 9 and 23 may be formed separately from each other.

  A resin fender panel 26 is provided to cover the lower portion of the pillar 20 from the outside. The fender panel 26 is detachably attached to the pillar 20 and can be arbitrarily replaced with another specification or a new one.

  The inner, outer panels 7 and 8 and the reinforcing panel 9 of the rocker 6 and the inner, outer panels 23 and 24 and the reinforcing panel 25 of the pillar 20 are made of sheet metal and formed by pressing.

  A plurality of pedestal portions 30 projecting outward are formed on the outer surface of the outer panel 8 in the middle in the vertical direction in the front upper portion of the rocker 6. These pedestal portions 30 are arranged intermittently and in a staggered manner in the front-rear direction of the vehicle body 2 in a side view of the vehicle body 2. And the middle part of the up-down direction in the lower end part of the outer panel 24 of the said pillar 20 and the reinforcement panel 25 is couple | bonded by the spot welding S with the protrusion end part of each said base part 30. FIG.

  A clearance 31 is formed between the outer side surface of the outer panel 8 of the rocker 6 and the lower edge 24a, 25a of the outer panel 24 and the reinforcing panel 25 of the pillar 20 respectively. In this case, the lower end edge 25a of the reinforcing panel 25 is positioned above the lower end edge 24a of the outer panel 24, and the lower end edge 25a of the reinforcing panel 25 is the lower end edge 24a of the outer panel 24 from the outside. Covered with wrinkles. The lower end edge 24a of the outer panel 24 is bent toward the inside of the vehicle body 2 using the gap 31, and the end surface 24b of the lower end edge 24a of the outer panel 24 is directed toward the inside lower side of the vehicle body 2. doing.

  At the time of electrodeposition coating of the vehicle body 2, the paint flows smoothly between both pedestal portions 30, 30 adjacent to each other in the front-rear direction of the vehicle body 2 and through the gap 31, so that the end surface 24 b of the outer panel 24 of the pillar 20 is Sufficient paint is applied to the lower end edge 24a to be included, and rust is prevented from occurring at the lower end edge 24a.

  According to the above configuration, the lower edge 24 a of the outer panel 24 is bent toward the inside of the vehicle body 2.

  For this reason, since the rigidity of the lower end edge portion 24a of the outer panel 24 of the pillar 20 is improved by bending thereof, the lower end edge portion 24a of the outer panel 24 is caused by an impact force from a running surface or the like when the vehicle 1 is running. Vibrating to be bent elastically is suppressed. Therefore, it is possible to prevent the paint applied to the lower edge 24a of the outer panel 24 from being easily peeled off by electrodeposition coating of the vehicle body 2, and to prevent the lower edge 24a of the outer panel 24 from generating rust. Is done.

  Further, as described above, since the lower edge 24 a of the outer panel 24 is bent toward the inside of the vehicle body 2, the end surface 24 b of the lower edge 24 a of the outer panel 24 is directed toward the inside of the vehicle 2. It becomes. For this reason, if the end surface 24b of the lower edge 24a of the outer panel 24 is left as a rough surface in a sheared state in the press working, coating of the coating becomes insufficient, and as a result, some rust is generated. However, since the rust is generated on the end surface 24b of the lower edge 24a of the outer panel 24 directed to the inner side of the vehicle body 2, the rust is prevented from being easily seen from the outside of the vehicle body 2. Is done. Therefore, the appearance of the vehicle body 2 is maintained in good appearance.

  Further, as described above, when the appearance of the vehicle body 2 is to be maintained in a good appearance, the end surface 24b of the lower end edge 24a of the outer panel 24 is allowed to remain as a rough surface in the above-described sheared state. Therefore, the above-described body side part structure can be easily formed as much as processing such as grinder finishing on the end face 24b can be omitted, which is beneficial in terms of productivity of the vehicle body 2.

  Although the above description is based on the illustrated example, the pillar 20 may be a center pillar or a rear pillar formed at a midway part or a rear part of the side wall of the vehicle body 2 in the front-rear direction.
