JP 11-49037 A

  By the way, at the time of a vehicle collision, an occupant, a luggage, or the like in the passenger compartment inside the vehicle body may collide with the door from the passenger compartment side to give an impact force. In this case, due to this impact force, the door tends to be displaced toward the outside of the side wall, while the locking device tries to maintain the state where the door is locked to the opening edge of the door opening. To do.

  Here, when the impact force is large, the impact force is applied around the reinforcement panel through an assembly of the attachment portion of the fastener to the outer panel and the reinforcement panel reinforcing the attachment portion. It tends to be deformed by being given to the part of the outer panel. Then, due to the deformation of the outer panel portion, the assembly is integrally displaced away from the inner panel toward the outer side of the side wall, and as a result, the side wall may be deformed excessively.

  The present invention has been made paying attention to the above situation, and an object of the present invention is to close a door opening formed on a side wall of a vehicle body of a vehicle and to be locked to an edge of the opening. When the side door is to be displaced toward the outer side of the side wall due to an impact force applied at the time of a vehicle collision, the side door is prevented from being excessively deformed. It is also possible to achieve this with a simple configuration, lightweight and inexpensive.

According to the first aspect of the present invention, a side wall 9 of the vehicle body 3 having an outer and inner panels 22, 23 facing each other in the width direction of the vehicle body 3 and having a hollow closed cross-section structure is formed on the side wall 9. The door opening 13, the side door 14 that closes the door opening 13 from the outside of the vehicle body 3, and the outer panel 22 at the opening edge of the door opening 13 can be attached and detached. A locking device 19 for locking and a reinforcing panel 25 provided in the inner space of the side wall 9 and having front and rear portions coupled to the outer panel 22 to reinforce the mounting portion of the locking device 19 to the outer panel 22. In the vehicle body side structure of the vehicle with
The vehicle body side structure is characterized in that a midway portion 25c of the reinforcing panel 25 in the front-rear direction of the vehicle body 3 is coupled to the inner panel 23.

The invention of claim 2 is a vehicle body side part structure in which a bent portion 25d is formed by bending a midway portion 25c of the reinforcing panel 25.
The vehicle body side structure according to claim 1, wherein a portion in the vicinity of the bent portion 25 d in the midway portion 25 c of the reinforcing panel 25 is coupled to the inner panel 23.

  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.

According to the first aspect of the present invention, there is provided an outer body that faces each other in the width direction of the vehicle body and is coupled to each other, a side wall of the vehicle body that has an inner panel and has a hollow closed cross-sectional structure, A side door that closes the door opening from the outside of the vehicle body so as to be openable and closable, a locking member that is attached to an outer panel at the opening edge of the door opening and that removably locks the door, and an internal space of the side wall. In a vehicle body side part structure provided with a reinforcing panel that is provided and has front and rear portions respectively coupled to the outer panel to reinforce the attachment portion of the locking tool to the outer panel.
A midway portion of the reinforcing panel in the front-rear direction of the vehicle body is coupled to the inner panel.

  For this reason, the door opening formed on the side wall of the vehicle body of the vehicle is closed, and the side door formed by the locking tool at the edge of the opening is given an impact force when the vehicle collides, and When trying to displace outwardly, the impact force is generated by the attachment portion of the locking device to the outer panel of the side wall via the locking device and the reinforcing panel reinforcing the attachment portion. It is supported by the inner panel through this reinforcing panel. Therefore, it is possible to more reliably prevent the side wall from being excessively deformed as compared with the conventional technique in which the impact force is mainly supported only by the outer panel and the reinforcing panel.

  Further, the prevention of the deformation of the side wall due to the impact force described above can be achieved with a simple configuration in which the middle part of the reinforcing panel is coupled to the inner panel. This can be achieved with a simple structure, light weight and low cost.

According to a second aspect of the present invention, there is provided a vehicle body side portion structure in which a bent portion is formed by bending a midway portion of the reinforcing panel.
A portion near the bent portion in the middle portion of the reinforcing panel is coupled to the inner panel.

  Here, as described above, an impact force is applied to the door, and the impact force is supported by the mounting portion of the locking tool to the outer panel and the reinforcing panel that reinforces the mounting portion. When the reinforcing panel is also supported by the inner panel, the bent portion in the middle of the reinforcing panel may be easily deformed so as to extend linearly by the tensile force based on the impact force. If the reinforcing panel is deformed in this way, the support of the impact force by the inner panel through the reinforcing panel tends to be insufficient, that is, the outer panel faces outward with respect to the inner panel. Therefore, the side wall tends to be deformed so as to be relatively displaced.

  However, according to the invention, since the vicinity of the bent portion in the middle part of the reinforcing panel is coupled to the inner panel, as described above, when the impact force is supported by the inner panel via the reinforcing panel, the reinforcing panel It is possible to prevent the middle bent portion from being deformed so as to extend linearly. Therefore, at the beginning when the impact force is applied to the door as described above, the reinforcing panel immediately and strongly opposes the impact force.

  As a result, when an impact force is applied to the door, it is immediately prevented that the side wall starts to be deformed so that the outer panel is relatively displaced outward with respect to the inner panel. In other words, the initial deformation of the side wall when an impact force is applied to the door is prevented from further inducing the next deformation and expanding from one to the next, and excessive deformation of the side wall is prevented. It is surely prevented beforehand.

  In the vehicle body side structure according to the present invention, the side door closed on the side wall of the vehicle body and locked to the opening edge of the vehicle side wall structure is caused by an impact force applied at the time of a vehicle collision. When trying to displace toward the outer side of the side wall, the side wall should not be deformed excessively. In order to achieve the object of achieving this with a simple configuration, light weight and low cost, the mode for carrying out the present invention is as follows.

Rails 15 that extend in the front-rear direction are provided on the door opening 13 on the side wall 9, on the lower opening edge, and on the portion of the side wall 9 behind the door opening 13. These rails 15 support the door 14 so as to move backward from the side of the door opening 13 and move backward. That is, the door 14 is slidable.

  If the door 14 is moved forward (rearward), the door 14 once moves from the door opening 13 side toward the outer side of the vehicle body 3 and then moves backward, thereby opening the door opening 13 ( Dash-dot line in FIG. 2). On the other hand, if the door 14 is moved backward (forward) from this state, the door 14 moves forward and then moves inward of the vehicle body 3, thereby closing the door opening 13 (FIG. 1). , 3-5, two-dot chain line, solid line in FIG.

  A locking tool that is attached to the rear opening edge of the door opening 13 by a fastener 17 and that removably locks the locked tool 18 that is attached to the rear end of the door 14 that has closed the door opening 13. 19 is provided. This locking tool 19 is called a striker.

  The side wall 9 is made of sheet metal and has outer and inner panels 22 and 23 that face each other in the width direction of the vehicle body 3 and are connected to each other by spot welding S1, and have a hollow closed cross-sectional structure.

  As described above, when the door 14 closes the door opening 13, the outer edge portion of the door 14 overlaps with the opening edge portion of the door opening 13 from the outer side of the side wall 9. In this case, the outer surface of the general portion 22a of the outer panel 22 of the side wall 9 and the outer surface of the door 14 are flush with each other.

  The outer panel 22 of the side wall 9 at the rear opening edge of the door opening 13 is inward and forward of the vehicle body 3 from the general part 22a of the outer panel 22 of the side wall 9 in a plan sectional view of the vehicle body 3 (FIGS. 1 and 5). A slant extending part 22b extending in the slanting direction, a front extending part 22c extending frontward from the extending end edge of the slant extending part 22b, and a front extending part 22c extending. And a flange portion 22d extending further forward from the end edge portion. And the flange part 22d of the said outer panel 22 and the front-end edge part of the said inner panel 23 are mutually couple | bonded by spot welding S1 mentioned above. Further, at the lower end portion of the side wall 9, the rear end edge portions of the outer and inner panels 22, 23 are respectively coupled to the rear wheel house 11 by spot welding S2 or the like.

  As described above, the locking tool 19 is attached to the inclined extending part 22b of the outer panel 22 at the middle part in the vertical direction of the rear opening edge of the door opening 13 by the pair of upper and lower fasteners 17 (17). ing. A reinforcing panel 25 and another reinforcing panel 26 that are provided in the inner space of the rear opening edge of the door opening 13 and reinforce the attachment portion of the locking tool 19 to the outer panel 22 are provided.

  A front portion 25a of the reinforcing panel 25 extends in the front-rear direction of the vehicle body 3, and a front end edge portion of the front portion 25a of the reinforcing panel 25 is sandwiched between a flange portion 22d of the outer panel 22 and a front end edge portion of the inner panel 23. Are coupled to each other by the spot welding S1. Further, the midway portion 25c of the reinforcing panel 25 in the front-rear direction of the vehicle body 3 is bent so that the rear portion 25b of the reinforcing panel 25 extends linearly from the front portion 25a side toward the outside and rear of the vehicle body 3. The bent portion 25d is formed in the midway portion 25c.

  The rear portion 25b of the reinforcing panel 25 is coupled to the inclined extending portion 22b of the outer panel 22 by spot welding S3. In addition, the inclined extending portion 22b of the outer panel 22, the rear portion 25b of the reinforcing panel 25, and the other reinforcing panel 26 are overlapped with each other, and are fastened together by the fastener 17 of the locking device 19 and coupled to each other. Yes. That is, the fastener 19 is attached to the joint portion of the rear portion 25 b of the reinforcing panel 25 to the outer panel 22 by the fastener 17.

  The upper edge of the reinforcing panel 25 is coupled to the outer panel 22 by spot welding S4. The midway part 25c of the reinforcing panel 25 is overlapped with the inner panel 23 and joined by a pair of upper and lower (a plurality of) couplers 28, 28 serving as fasteners. The locking tool 19 is arranged between the upper and lower couplers 28 in the vertical direction. More specifically, in the plan sectional view of the vehicle body 3 (FIGS. 1 and 5), a portion in the vicinity of the bent portion 25d in the midway portion 25c of the reinforcing panel 25 is coupled to the inner panel 23 by the coupling tool 28. Yes.

  The reinforcing panel 25 is thicker than the outer and inner panels 22 and 23. The lower end edge portion of the reinforcing panel 25 is folded and bent so as to have a U-shaped cross section, and the strength and rigidity of the reinforcing panel 25 are enhanced by the bent reinforcing portion 25e. In addition, as described above, the inner panel 23 and the reinforcing panel 25 between the lower couplers 28 and 28 have a hollow closed cross-sectional structure in the rear view of the vehicle body 3 (FIG. 4). As a result, the attachment portion of the locking tool 19 to the outer panel 22 is further reinforced.

  In addition, a trim 30 is provided on the surface of the side wall 9 on the side of the compartment 2.

  According to the above configuration, the midway portion 25 c of the reinforcing panel 25 in the front-rear direction of the vehicle body 3 is coupled to the inner panel 23 by the coupling tool 28.

  For this reason, the door opening 13 formed in the side wall 9 of the vehicle body 3 of the vehicle 1 is closed, and the side door 14 formed by the locking tool 19 on the opening edge of the side door 14 causes the impact force when the vehicle 1 collides. When F is applied and it is going to be displaced toward the outer side of the side wall 9, the impact force F is applied to the outer panel 22 of the side wall 9 via the locking tool 19. And the reinforcing panel 25 that reinforces the attachment portion, and is also supported by the inner panel 23 via the reinforcing panel 25. Therefore, it is possible to more reliably prevent the side wall 9 from being excessively deformed as compared with the conventional technique in which the impact force F is mainly supported only by the outer panel 22 and the reinforcing panel 25.

  Further, since the deformation of the side wall 9 due to the impact force F can be prevented by a simple configuration in which the middle portion 25c of the reinforcing panel 25 is coupled to the inner panel 23, it is sufficient to provide no additional reinforcing material. The prevention of the deformation of the side wall 9 can be achieved with a simple structure, light weight and low cost.

  In the vehicle body side structure in which the middle part 25c of the reinforcing panel 25 is bent to form a bent part 25d, a portion in the vicinity of the bent part 25d in the middle part 25c of the reinforcing panel 25 is The inner panel 23 is connected.

  Here, as described above, an impact force F is applied to the door 14, and the impact force F is applied by the attachment portion of the locking tool 19 to the outer panel 22 and the reinforcing panel 25 reinforcing the attachment portion. When supported by the inner panel 23 via the reinforcing panel 25, the bent portion 25 d of the midway portion 25 c of the reinforcing panel 25 is straightened by the tensile force based on the impact force F. May be easily deformed to extend. If the reinforcing panel 25 is deformed as described above, the support of the impact force F by the inner panel 23 via the reinforcing panel 25 tends to be insufficient. That is, the outer panel is more than the inner panel 23. The side wall 9 tends to be deformed so that 22 is relatively displaced outward.

  However, according to the above configuration, the portion near the bent portion 25d in the midway portion 25c of the reinforcement panel 25 is coupled to the inner panel 23 by the coupling tool 28, so that the impact force F is passed through the reinforcement panel 25 as described above. When supported by the inner panel 23, the bent portion 25d of the midway portion 25c of the reinforcing panel 25 is prevented from being deformed so as to extend linearly. Therefore, at the beginning when the impact force F is applied to the door 14 as described above, the reinforcing panel 25 immediately and strongly opposes the impact force F.

  As a result, when an impact force F is applied to the door 14, the side wall 9 is immediately prevented from starting to deform so that the outer panel 22 is relatively displaced outward with respect to the inner panel 23. That is, the initial deformation of the side wall 9 when the impact force F is applied to the door 14 is further prevented from inducing the next deformation and expanding from the next to the next. Excessive deformation is reliably prevented.

  Further, as described above, the midway portion 25c of the reinforcing panel 25 is bent so that the rear portion 25b of the reinforcing panel 25 extends linearly from the front portion 25a side toward the outer side of the vehicle body 3, so that the outer panel 22 is connected to the outer panel 22. The locking tool 19 is attached to the joint portion of the rear portion 25b of the reinforcing panel 25.

  For this reason, the attachment part of the latching tool 19 to the outer panel 22 and the inner panel 23 are connected to each other by the linearly extending rear part 25 b of the reinforcing panel 25. Therefore, the impact force F is applied to the door 14 as described above, and the impact force F is supported by the attachment portion of the locking device 19 to the outer panel 22 and the reinforcement panel 25 that reinforces the attachment portion. In addition, when the reinforcing panel 25 is also supported by the inner panel 23 via the linearly extending rear portion 25b, the impact force F is initially applied to the door 14 as described above. A tensile stress is immediately generated in the rear portion 25b of the reinforcing panel 25, and this tensile stress quickly and strongly opposes the impact force F.

  As a result, when an impact force F is applied to the door 14, the side wall 9 is immediately prevented from starting to deform so that the outer panel 22 is relatively displaced outward with respect to the inner panel 23. That is, the initial deformation of the side wall 9 when the impact force F is applied to the door 14 is further reliably prevented from inducing the next deformation and expanding from the next to the next. Further, excessive deformation of the side wall 9 is surely prevented.

  Here, in the vehicle 1, the outer edge portion of the door 14 overlaps with the opening edge portion of the door opening 13 formed on the side wall 9 of the vehicle body 3 from the outside of the side wall 9, and these Increasing the thickness dimension of the overlapping portion has a limit from the viewpoints of downsizing the vehicle body 3 and securing the space of the vehicle compartment 2. For this reason, the thickness dimension in the width direction of the vehicle body 3 at the front end portion of the rear opening edge of the door opening 13 tends to be small, and it is not easy to ensure sufficient strength and rigidity.

  However, according to the reinforcing structure of the opening edge portion of the door opening 13 by the reinforcing panel 25 described above, excessive deformation of the side wall 9 when the impact force F is applied to the door 14 is more reliably prevented. .

  Although the above is based on the illustrated example, the door 14 may be of a single-opening type that is pivotally supported by the vehicle body 3 so as to reciprocately rotate outwardly of the vehicle body 3. The door 14 may be a front door. The coupler 28 may be a coupling means by welding such as a rivet or a spot.
