Description

  The present invention relates to a vehicle body structure in which a door is connected to a vehicle body via a connecting member.

  A slide door that is slidable in the front-rear direction of the vehicle body is attached to the vehicle body via a connecting member. As a conventional technique related to such a vehicle body structure, there is a technique disclosed in Patent Document 1.

  As shown in Patent Document 1, a vehicle door is provided with a center roller attached substantially at the center in the height direction of the door, and the center roller is attached to the vehicle body so as to be slidable on the vehicle body. That is, it is attached to the vehicle body via a center roller as a connecting member. The center roller is supported by a reinforcing member disposed on the back surface of the panel.

  The attachment position of the connecting member (center roller) with respect to the front-rear direction of the door panel affects the parting between the door and the vehicle body. That is, when the connecting member is attached at an incorrect position in the front-rear direction, the appearance of the vehicle is degraded. For this reason, the connecting member needs to be attached to the door panel at an accurate position, particularly in the front-rear direction.

  In this regard, as an example of a method for attaching the connecting member supported by the reinforcing member to an accurate position, a method illustrated in FIG. 8 can be considered.

  Please refer to FIG. FIG. 8 shows a portion of the door panel as viewed from the outside of the vehicle. A method of temporarily holding the reinforcing member 103 on the door panel 102 in advance when attaching the connecting member 101 to the door panel 102 is conceivable. The reinforcing member 103 is temporarily held by a temporary holding band 104 extending in the vertical direction and a second temporary holding band 105 extending in the longitudinal direction of the vehicle body. The temporary holding bands 104 and 105 are welded to the door panel 102.

  The temporary holding bands 104 and 105 hold the reinforcing member 103 so as to allow the displacement of the reinforcing member 103. This displaceable amount becomes an adjustment margin when positioning the connecting member 101.

  Next, the connecting member 101 is temporarily fastened to the reinforcing member 105. The connecting member 101 is connected to the reinforcing member 105 using bolts 106. At this time, the bolts 106 are fastened to such an extent that displacement of the connecting member 101 and the reinforcing member 105 is allowed.

  Next, the connecting member 101 is positioned, and the bolts 106 and 106 are finally fastened to the reinforcing member 105. Accordingly, the door panel 102 is sandwiched between the connecting member 101 and the reinforcing member 105, and the connecting member 101 can be fixed at a predetermined position of the door panel 102.

  By the way, when such an attachment method is adopted, it is necessary to weld the two temporary holding bands 104 and 105 to the door panel 102, respectively. Considering reduction of the number of parts, simplification of the mounting work, and weight reduction of the door, it is preferable that the temporary holding band 104 can be made into one sheet.

  However, if the two temporary holding bands 104 and 105 are simply one, the reinforcing member 103 may fall during the attaching operation of the connecting member 101. On the other hand, if the temporary holding band 104 having a small gap is used in order to prevent the reinforcing member 103 from falling, an adjustment allowance for positioning cannot be secured.

Japanese Patent No. 4551689

  An object of the present invention is to provide a technique capable of suppressing the dropping of the reinforcing member even when the number of parts is small, when the connecting member is attached.

According to the invention according to claim 1, in the vehicle body structure in which the door is connected to the vehicle body via the connecting member, and the opening formed in the vehicle body can be opened and closed by the door.
The door panel constituting the door is sandwiched between the connecting member and a reinforcing member that reinforces the door panel,
The door panel is provided with a regulating member that regulates movement of the reinforcing member in the vehicle width direction,
The reinforcing member has a reinforcing member protrusion protruding toward the door panel,
The reinforcing member protrusion is engaged with an engagement hole provided in the door panel,
A vehicle body structure is provided in which a front-rear direction width of the reinforcing member protrusion is smaller than a front-rear direction width of the engagement hole.

  Preferably, the reinforcing member protrusion is formed by press molding.

As described in claim 3, preferably, the vertical width of the protrusion of the reinforcing member is formed substantially the same as the vertical width of the engagement hole,
Two or more reinforcing member protrusions and two engagement holes are formed.

As described in claim 4, preferably, the reinforcing member is provided with at least two projecting portions projecting away from the door panel,
At least a part of the restricting member is located between the protrusions.

  As described in claim 5, preferably, a screw hole is formed in the protrusion.

As described in claim 6, preferably, the restriction member is a member made of a long metal plate,
The total length of the gaps formed between the regulating member and the upper and lower ends of the reinforcing member is the sum of the engagement hole and the upper and lower ends of the reinforcing member protrusion. It is larger than the total length of the gaps formed between them.

  In the invention which concerns on Claim 1, the reinforcement member protrusion part which is formed in a reinforcement member and protrudes toward a door panel is engaged with the engagement hole provided in the door panel. When attaching the connecting member, the reinforcing member may fall off. In such a case, the reinforcing member protrusion is caught in the engagement hole, so that the dropping of the reinforcing member is suppressed. For this reason, even when the number of regulating members for temporarily holding the reinforcing member is reduced at the time of attaching the connecting member, a sufficient adjustment allowance can be ensured.

  In addition, the front-rear direction width of the reinforcing member protrusion is smaller than the front-rear direction width of the engagement hole. In the front-rear direction, the reinforcing member protrusion can move with respect to the engagement hole. It is possible to provide a margin for position adjustment without using a regulating member extending in the longitudinal direction of the vehicle body. Both positioning accuracy and door weight reduction are compatible.

  In the invention which concerns on Claim 2, the reinforcement member protrusion is formed by press molding. Since only the press molding is performed without joining the separate members, the joining process, the weight of the separate members, and the cost due to an increase in parts can be reduced.

  In the invention according to claim 3, the vertical width of the reinforcing member protrusion is formed substantially the same as the vertical width of the engaging hole, and two or more reinforcing member protrusions and engaging holes are formed. Has been. The rotation of the reinforcing member can be restricted during the connecting operation of the connecting member.

  In the invention according to claim 4, the reinforcing member is provided with at least two projecting portions projecting away from the door panel, and at least a part of the regulating member is located between the projecting portions. Since the restricting member is arranged on the line segment connecting the protruding portions, the movement of the reinforcing member can be restricted in the direction orthogonal to the vehicle width direction, and the reinforcing member protruding portion is engaged with the engaging hole. Even in the previous stage, it is possible to temporarily fix the regulating member simply by pressing it against the reinforcing member.

  In the invention which concerns on Claim 5, the screw hole is formed in the protrusion part. The length of the threaded direction in the vehicle width can be ensured at the protruding portion. The position restriction of the reinforcing member and screw cutting can be shared by one member. In addition, since the protruding portion is provided with a screw cut, the other portions can be made thin, and the reinforcing member can be lightened.

  In the invention which concerns on Claim 6, the sum total of the length of the clearance gap each formed between the limitation member and the upper and lower end part of a reinforcement member is the upper and lower ends of an engagement hole and a reinforcement member protrusion. And the sum of the lengths of the gaps formed between the two portions. Since the regulating member is usually formed by press molding, the regulating member may not be highly accurate due to the spring back. On the other hand, the reinforcing member protrusion can be formed with a simple convex shape, and can be formed with high accuracy. After assembly, it is sufficient that the vertical direction is positioned by the reinforcing member protrusion and the engagement hole that can be formed with high accuracy, and the regulating member itself can be prevented from being involved in positioning. Is never required.

<Example>

  Please refer to FIG. FIG. 1 shows a wagon car as an example of the vehicle 10. The vehicle 10 has an opening 12 formed at the rear side of a vehicle body 11, and a door 13 is provided so that the opening 12 can be opened and closed. The door 13 is a so-called sliding door that can slide on a rail 14 provided on a side surface of the vehicle body 11. The door 13 is supported by the vehicle body 11 so as to be slidable in the front-rear direction.

  Please refer to FIG. The door 13 is formed by covering an inner panel 20 (door panel 20) disposed on the vehicle compartment side with an outer panel 16 that is visible from the outside of the vehicle.

  A window opening 21 is formed in the upper portion of the inner panel 20. A corner stiffener 17 is joined along a corner portion 22 formed in the lower rear portion of the window opening 21 of the inner panel 20. The corner stiffener 17 is a plate material for reinforcing the inner panel 20.

  A rear latch stiffener 18 is joined to the lower portion of the corner stiffener 17. The rear latch stiffener 18 is a plate member joined to the inner panel 20. The rear latch stiffener 18 increases the mounting rigidity of the latch device provided at the rear portion of the door 13.

  Please refer to FIG. 3 and FIG. A center roller 19 (connecting member 19) is attached to the side of the compartment Vi where the inner panel 20, the corner stiffener 17, and the rear latch stiffener 18 are overlapped. The center roller 19 is supported by a rail 14 (see FIG. 1) formed on the vehicle body 11 (see FIG. 1). That is, the door 13 is connected to the vehicle body 11 via the center roller 19. As the structure of the center roller 19 and the rail 14, a well-known structure is adopted.

  A reinforcing member 30 is attached to the outside of the vehicle where the inner panel 20, the corner stiffener 17, and the rear latch stiffener 18 are overlapped. The reinforcing member 30 is provided to increase the attachment rigidity of the center roller 19. The reinforcing member 30 sandwiches the inner panel 20, the corner stiffener 17, and the rear latch stiffener 18 together with the center roller 19.

  The reinforcement member 30 is restricted from moving in the vehicle width direction (left-right direction in FIG. 4) by the temporary holding band 40 (the restriction member 40). The temporary holding band 40 is a long metal plate member formed by press molding. The temporary holding band 40 is a member that restricts movement of the reinforcing member 30 in the vehicle width direction and allows movement in the front-rear direction (left-right direction in FIG. 3) when the center roller 19 is attached to the inner panel 20. It is.

  Please refer to FIG. 3 and FIG. FIG. 5 shows the reinforcing member 30 as viewed from the passenger compartment side. That is, FIG. 5 shows the reinforcing member 30 shown in FIG. 3 as viewed from the back side.

  The reinforcing member 30 is formed in a substantially hexagonal plate-like member by a reinforcing-side pin insertion round hole 31, a reinforcing-side pin insertion long hole 32, projecting portion insertion holes 33, 33, and reinforcing member projecting portions 34, 34. In addition, the protrusions 35 and 35 are inserted into the protrusion insertion holes 33 and 33.

  Details of the reinforcing-side pin insertion round hole 31 and the reinforcing-side pin insertion long hole 32 will be described later.

  The reinforcing member protrusions 34, 34 protrude toward the inner panel 20. The reinforcing member protrusions 34 and 34 are formed by pressing a part of the plate material.

  Please refer to FIG. 6 and FIG. The reinforcing member protrusions 34 and 34 are engaged with engagement holes 23 and 23 formed in the inner panel 20. The engagement holes 23 are long holes that are long in the front-rear direction. The diameters of the reinforcing member protrusions 34 and 34 are slightly smaller than the upper and lower widths of the engagement holes 23 and 23.

  Please refer to FIG. The protrusion 35 is a boss to which the bolt 51 is fastened, and is fixed while being inserted into the protrusion insertion hole 33 (see FIG. 5). A screw hole 35 a into which the bolt 51 can be screwed is formed in the protruding portion 35.

  Please refer to FIG. The temporary holding band 40 includes leg portions 41 and 41 welded to the rear latch stiffener 18, and rising portions 42 and 42 raised from the leg portions 41 and 41 along the edge of the reinforcing member 30. The movement restricting portion 43 that is passed between the rising portions 42 and 42 and is in contact with the reinforcing member 30.

  Beads 42 a, 42 a, 43 a are continuously formed from the rising portions 42, 42 to the movement restricting portion 43. The movement restricting portion 43 passes between the protruding portions 35 and 35 and extends in the vertical direction. In the movement restricting portion 43, restricting portion side pin insertion holes 43b and 43b are formed at portions avoiding the beads 42a, 43a and 42a.

  Please refer to FIG. The restricting portion side pin insertion holes 43b and 43b are overlapped with the reinforcement side pin insertion round hole 31 and the reinforcement side pin insertion long hole 32, respectively. The temporary holding band 40 can be positioned with respect to the reinforcing member 30 by inserting the pins 52 and 52 after overlapping. This positioning is performed at the time of welding the movement restricting portion 43 to the inner panel 20 (rear latch stiffener 18), and the pins 52 and 52 can be removed after the welding. Details will be described later.

  Please refer to FIG. 3 and FIG. The attachment position of the center roller 19 with respect to the front-rear direction of the inner panel 20 affects the parting between the door 13 and the vehicle body 11 (see FIG. 1). That is, when the center roller 19 is attached to an incorrect position in the front-rear direction, the appearance of the vehicle 10 is deteriorated. For this reason, the center roller 19 needs to be attached to the inner panel 20 at an accurate position, particularly in the front-rear direction. A method for attaching the center roller 19 supported by the reinforcing member 30 to an accurate position will be described below.

  First, the reinforcing member protrusion 34 is engaged with the engagement hole 23 formed in the inner panel 20. The reinforcing member 30 is positioned in the vertical direction. This step can be said to be a step in which the reinforcing member protrusion 34 is engaged with the engaging hole 23 of the inner panel 20 to position the reinforcing member 30 in the vertical direction.

  At this time, the temporary holding band 40 may be coupled to the reinforcing member 30 using pins 52 and 52 (see FIG. 5). That is, it is preferable that the temporary holding band 40 be connected to a predetermined position of the reinforcing member 30 in the step of positioning the reinforcing member 30 in the vertical direction. This is because when the temporary holding band 40 is connected to the reinforcing member 30, the temporary holding band 40 is also integrally positioned when the reinforcing member 30 is positioned in the vertical direction.

  Next, the legs 41 and 41 of the temporary holding band 40 are welded to the inner panel 20 (rear latch stiffener 18). By welding, the movement of the reinforcing member 30 positioned in the vertical direction in the vehicle width direction is restricted. This step can be said to be a step of joining the temporary holding band 40 to the inner panel 20 and restricting the movement of the reinforcing member 30 positioned in the vertical direction in the vehicle width direction. When the joining of the temporary holding band 40 is finished, the pins 52 and 52 are removed.

  Next, the process of matching the center roller 19 with the surface opposite to where the reinforcing member 30 of the inner panel 20 is disposed is performed.

  Next, the bolt 51 is inserted from the center roller 19 toward the protruding portion 35 of the reinforcing member 30 to temporarily fix the center roller 19 to the reinforcing member 30. Temporary fixing refers to a state in which the center roller 19 and the reinforcing member 30 are connected while allowing movement in the front-rear direction.

  Next, a process of aligning the temporarily fixed center roller 19 and the reinforcing member 30 at predetermined positions in the front-rear direction is performed.

  Next, a step of fixing the center roller 19 and the reinforcing member 30 that are aligned with a predetermined position of the inner panel 20 is performed. By tightening the bolt 51, the center roller 19 and the reinforcing member 30 are fixed at predetermined positions of the inner panel 20.

  According to the present invention as described above, the following effects can be obtained.

  Please refer to FIG. 3 and FIG. A reinforcing member protrusion 34 formed on the reinforcing member 30 and protruding toward the inner panel 20 is engaged with an engaging hole 23 provided in the inner panel 20. When the center roller 19 is attached, the reinforcing member 30 may fall off. In such a case, the reinforcing member protrusion 34 is caught in the engagement hole 23, so that the dropping of the reinforcing member 30 is suppressed. The movement in the vehicle width direction is regulated by the temporary holding band 40. For this reason, even when the temporary holding band 40 for temporarily holding the reinforcing member 30 is reduced to one when the center roller 19 is attached, a sufficient adjustment allowance can be secured.

  In addition, the front-rear direction width of the reinforcing member protrusion 34 is smaller than the front-rear direction width of the engagement holes 23, 23. The reinforcing member protrusion 34 can move with respect to the engagement hole 23 in the front-rear direction. Without using a regulating member (see FIG. 8) extending in the longitudinal direction of the vehicle body, it is possible to provide a margin for position adjustment. Both positioning accuracy and weight reduction of the door 13 are compatible.

  Furthermore, the reinforcing member protrusion 34 is formed by press molding. Since only the press molding is performed without joining the separate members, the joining process, the weight of the separate members, and the cost due to an increase in parts can be reduced.

  Further, the vertical width of the reinforcing member protrusion 34 is formed substantially the same as the vertical width of the engagement holes 23, 23, and two or more reinforcing member protrusions 34 and engagement holes 23 are formed. Has been. It is possible to restrict the rotation of the reinforcing member 30 when the center roller 19 is attached.

  Further, the reinforcing member 30 is provided with at least two projecting portions 35 and 35 projecting away from the inner panel 20, and at least a part of the temporary holding band 40 is located between the projecting portions 35 and 35. ing. Since the temporary holding band 40 is disposed on the line segment connecting the protruding portions 35 and 35, the movement of the reinforcing member 30 can be restricted in the direction orthogonal to the vehicle width direction, and the reinforcing member protruding portion 34 is Even before the engagement with the engagement hole 23, the temporary holding band 40 can be temporarily fixed by simply pressing the temporary holding band 40 against the reinforcing member 30.

  Furthermore, screw holes 35a, 35a are formed in the protrusions 35, 35. It is possible to secure the length in the vehicle width direction of threading at the projecting portions 35 and 35. The position restriction of the reinforcing member 30 and screw cutting can be shared by one member. Further, since the protrusions 35 and 35 are provided with screw cutting, other portions can be made thin, and the reinforcing member 30 can be lightened.

  Please refer to FIG. 3 and FIG. The reinforcing member 30 is formed with reinforcing side pin insertion holes 31 and 32 (reinforcing side pin insertion round hole 31 and reinforcing side pin insertion long hole 32). The temporary holding band 40 is formed with restricting portion side pin insertion holes 43b and 43b. The common pins 52 and 52 can be inserted into the reinforcing side pin insertion holes 31 and 32 and the restriction portion side pin insertion holes 43b and 43b. The temporary holding band 40 is positioned with respect to the reinforcing member 30 by inserting the pins 52 and 52. For this reason, when the reinforcing member protrusion 34 is engaged with the engagement hole 23 of the inner panel 20, the temporary holding band 40 can also be positioned integrally. Thereby, the temporary holding band 40 can be easily joined to a predetermined position of the inner panel 20. Note that the temporary holding band 40 only needs to be able to restrict the movement of the reinforcing member 30 in the vehicle width direction, and thus some displacement in the front-rear direction is allowed.

  The reinforcement-side pin insertion holes 31 and 32 and the restricting portion side pin insertion holes 43b and 43b are formed two by two. Thereby, it is possible to prevent the temporary holding band 40 from rotating with respect to the reinforcing member 30.

  One of the two reinforcing side pin insertion holes 31 and 32 is preferably a long hole. This is because dimensional errors that are inevitably generated between products can be absorbed.

  Please refer to FIG. 4 and FIG. The total length L1 + L2 of the gaps formed between the temporary holding band 40 and the upper and lower ends of the reinforcing member 30 is determined by the engagement hole 23 and the upper and lower ends of the reinforcing member protrusion 34. Are larger than the total length L3 + L4 of the gaps formed between the two. Since the temporary holding band 40 is usually formed by press molding, the temporary holding band 40 may not be highly accurate due to the spring back. On the other hand, the reinforcing member protrusion 34 can be formed with a simple convex shape, and can be formed with high accuracy. After assembly, it is sufficient that the vertical direction is positioned by the reinforcing member protrusion 34 and the engagement hole 23 that can be formed with high accuracy, and the temporary holding band 40 itself can be prevented from being involved in positioning. High molding accuracy of the holding band 40 is not required.

  The center roller 19 and the reinforcing member 30 sandwich the reinforcing panels 17 and 18 (the corner stiffener 17 and the rear latch stiffener 18) that reinforce the inner panel 20 in addition to the inner panel 20. By sandwiching these reinforcing panels 17 and 18, the attachment rigidity of the center roller 19 can be increased.

  In the embodiment, the vehicle body structure according to the present invention has been described by taking the slide door attached to the left side of the vehicle as an example, but the same configuration can be adopted for the slide door attached to the right side of the vehicle. At this time, the description of the left side of the vehicle body can be appropriately read as the description of the right side of the vehicle body.

  That is, the present invention is not limited to the examples as long as the operations and effects of the present invention are exhibited.

  The vehicle body structure of the present invention is suitable for a wagon car.
