Description

  The present invention relates to a vehicle body structure with a tailgate in which an opening (rear opening) is provided at a rear portion of a vehicle body, and a tailgate is supported on an upper portion of the rear opening so as to be rotatable in the vertical direction.

As a vehicle body structure with a tailgate, a rear opening (main opening) is provided at the rear of the vehicle body, a tailgate is provided at the top of the rear opening so that it can be opened and closed vertically, and a door opening (sub-opening) is provided at the tailgate. It is known that left and right auxiliary doors are provided at the door opening so as to be openable and closable in the lateral direction (vehicle width direction).
In this vehicle body structure, left and right auxiliary doors are arranged above the lower portion of the tailgate (see, for example, Patent Document 1).

Utility Model Registration No. 2514650

In the vehicle body structure of Patent Document 1, the left and right auxiliary doors are arranged above the lower portion of the tailgate, so that the lower end of the door opening is restricted by the lower portion of the tailgate. For this reason, it is difficult to widen the door opening downward, and there is a possibility that the lower part of the tailgate hinders passengers from getting on and off.
As a means for expanding the door opening downward, it is conceivable to extend the lower ends of the left and right subdoors to the lower end of the tailgate.

However, in the vehicle body structure of Patent Document 1, a gap is formed between the left and right subdoors when the left and right subdoors are closed. Therefore, when the tailgate is opened in the rain, water accumulates in the gap between the left and right subdoors. When the tailgate is closed, the accumulated water is guided downward through a gap between the left and right subdoors.
For this reason, when the lower ends of the left and right sub doors are extended to the lower end of the tail gate, it is conceivable that water guided downward through the gap between the left and right sub doors falls on the operator of the tail gate.

  An object of the present invention is to provide a vehicle body structure with a tailgate that can widen the sub-opening downward and can prevent water from falling on an operator who closes the tailgate.

  According to a first aspect of the present invention, there is provided a vehicle body structure with a tailgate having a tailgate supported by the vehicle body at an upper portion of the opening so as to open and close an opening provided at a rear portion of the vehicle body in a vertical direction. The tailgate is provided with a sub-opening that opens to the tailgate and communicates with the opening, and a sub-door that opens and closes the sub-opening, and the tail gate and the sub-door are closed. The lower end of the auxiliary door is disposed at substantially the same height as the lower end of the tailgate, and the outer surface of the tailgate and the outer surface of the auxiliary door are formed in substantially the same plane in the longitudinal direction of the vehicle body. A separation portion is provided that is spaced apart by a predetermined distance between a side edge on the sub door side of the outer surface of the tail gate and a side edge on the tail gate side of the outer surface of the sub door, The tailgate, Provided on any one of the auxiliary doors, provided with a plate-like portion that is in front of the separation body and overlaps the separation portion, and a convex portion that protrudes toward the rear of the vehicle body is provided on the plate-like portion. It is characterized by that.

  According to a second aspect of the present invention, the convex portion is provided in the vicinity of the lower end of the tailgate.

Here, when the tailgate is opened in the rain, water accumulates in the plate-like portion through the separation portion. When the tailgate is closed, the water accumulated in the plate-like portion is guided along the plate-like portion below the tailgate.
Therefore, in claim 2, a convex portion is provided in the vicinity of the lower end of the tailgate.

  According to a third aspect of the present invention, the tailgate is positioned at the rearmost side of the vehicle body in the center in the vehicle width direction, and is gradually positioned at the front of the vehicle body from the center in the vehicle width direction toward the vehicle width end. It is provided in the position offset in the vehicle width direction from the vehicle width direction center.

  According to a fourth aspect of the present invention, the convex portion has an inclined portion that smoothly inclines from the front of the vehicle body to the rear of the vehicle body as it goes downward from the upper edge portion, starting from the upper edge portion that forms the upper edge of the convex portion. The upper edge portion is located at the same height in the vertical direction in the entire vehicle width direction.

  According to a fifth aspect of the present invention, the convex portion has a planar top surface portion connected to the lower end of the inclined portion, and a decoration member of the tailgate is fixed to the top surface portion.

In the invention which concerns on Claim 1, the tailgate and the subdoor were closed, and the lower end of the subdoor was arrange | positioned in the substantially same height position as the lower end of a tailgate. Therefore, since the lower end of a subdoor can be lowered below, the lower end of a subopening can be lowered below.
That is, the sub-opening can be expanded downward. Thereby, a passenger | crew can get on and off smoothly from a subopening, and a passenger | crew's boarding / alighting property can be improved.

Further, a separation portion is provided that is spaced apart by a predetermined distance between a side edge on the subdoor side of the outer surface of the tailgate and a side edge on the tailgate side of the outer surface of the subdoor.
Therefore, when the tailgate is opened in the rain, water accumulates in the plate-like portion through the separation portion. When the tailgate is closed, it is considered that when the tailgate is closed, the water is guided along the plate-like portion to the lower side of the tailgate, and the water splashes vigorously from the lower end of the tailgate.

Therefore, the plate-like portion is overlapped with the separation portion, and the convex portion is protruded from the plate-like portion toward the rear of the vehicle body.
Therefore, when the tailgate is closed in a state where water is accumulated in the plate-like portion, the momentum of the water flow guided downward along the plate-like portion is suppressed by the convex portion, and the flow becomes gentle.
Thereby, it is possible to prevent water from splashing from the lower end of the tailgate, and to prevent the operator who closes the tailgate from falling.

In the invention according to claim 2, the convex portion is provided near the lower end of the tailgate. Thus, when the tailgate is closed, most of the water accumulated in the plate-like portion can be guided to the convex portion.
Thereby, it becomes possible to suppress the momentum of most of the water accumulated in the plate-like portion with the convex portion, and it is possible to more reliably prevent water from falling on the operator who closes the tailgate.

In the invention according to claim 3, the center of the tailgate in the vehicle width direction is positioned most rearward of the vehicle body, and the vehicle width end of the tailgate is gradually directed from the vehicle width direction of the vehicle to the front of the vehicle body.
Therefore, in the state where the tailgate is opened, the center of the tailgate in the vehicle width direction is arranged at the highest position. As a result, rainwater that has fallen on the tailgate is guided toward the end of the vehicle width.

Here, the separation portion is provided at a position offset (shifted) in the vehicle width direction from the center in the vehicle width direction. Therefore, a lot of rain water that has fallen on the tailgate can be guided to the separation portion and stored in the plate-like portion.
Thereby, it is possible to efficiently suppress the momentum of a large amount of rainwater that has fallen on the tailgate so as to have a gentle flow at the convex portion.

In the invention which concerns on Claim 4, the upper edge part of the convex part was located in the same height in the up-down direction in the vehicle width direction whole region. Therefore, the water (rain water) that has flowed to the upper edge portion of the convex portion can be uniformly guided from the upper edge portion to the inclined portion.
Furthermore, the inclined part was smoothly inclined backward from the upper edge of the convex part toward the rear of the vehicle body. Therefore, the water (rain water) that has reached the inclined portion can be uniformly guided downward by the inclined portion without retaining the water. Thereby, the water (rain water) collected by the plate-shaped part can be drained uniformly from the lower end of the tailgate, and a good drainage state can be secured.

  In the invention which concerns on Claim 5, a top surface part was connected to the lower end of an inclination part, and the top surface part was formed in planar shape. Therefore, it is possible to prevent the flow of water guided from the inclined portion to the top surface portion from being obstructed by the top surface portion. Thereby, the favorable drainage state of the water (rain water) collected by the plate-shaped part is securable.

By the way, an outer surface of the tailgate and an outer surface of the sub door (that is, a decorative member) are provided on the rear side of the vehicle body of the plate-like portion.
Therefore, by forming the top surface portion provided on the plate-like portion in a flat shape, the top surface portion can be used also as an attachment portion for attaching a decorative member provided on the rear side of the vehicle body of the plate-like portion. Thereby, since it is not necessary to provide the attachment part which attaches a decoration member separately, the number of parts can be suppressed and the structure can be simplified.

A gate window glass 17, a gate decoration member (decoration member) 18 provided below the gate window glass 17, and a sub door 20 that opens and closes the gate body 16 are provided.

As shown in FIG. 2, when the tailgate 15 is opened, the lower end 15 a of the tailgate 15 is disposed at substantially the same height as the upper end 15 b of the tailgate 15.
However, FIG. 2 shows a state in which the lower end 15a of the tailgate 15 is disposed slightly below the upper end 15b in order to facilitate understanding of the configuration.
By opening the tailgate 15, the tailgate 15 is disposed substantially horizontally at the position of the upper frame portion 13 c of the rear opening frame portion 13. In this state, the rear opening 14 of the rear opening frame 13 is opened, and the passenger compartment 22 and the vehicle exterior 23 are communicated with each other through the rear opening 14.

On the other hand, as shown in FIG. 1, when the tailgate 15 is closed, the lower end 15 a of the tailgate 15 is disposed below the upper end 15 b of the tailgate 15. That is, the tailgate 15 is disposed substantially vertically by closing the tailgate 15.
In this state, the rear opening 14 of the rear opening frame 13 is closed by the tailgate 15.

As shown in FIGS. 2 and 3, the gate body 16 is formed in a substantially rectangular shape so that the rear opening 14 of the rear opening frame 13 can be opened and closed, and the upper end 16 a is the upper frame 13 c of the rear opening frame 13. Is supported so as to be vertically rotatable via a gate hinge.
The gate body 16 is formed in a curved shape so as to bulge toward the outside 23 in the vehicle width direction.

Further, the gate body 16 includes a window opening frame portion 26 opened substantially in the upper right half of the right side, and a door opening frame portion 28 opened substantially throughout the left side of the gate body 16.
The window inner frame 26 a of the window opening frame portion 26 and the door inner frame 28 a of the door opening frame portion 28 are also used as the partition frame 31. The partition frame 31 extends linearly in the vertical direction from the upper end 16 a to the lower end 16 b of the gate body 16.

  As shown in FIG. 4, the gate main body 16 includes an inner panel 34 located on the vehicle compartment 22 side, an outer panel 35 located on the vehicle exterior 23 side, and a reinforcing member 37 interposed in a part forming the partition frame 31. Prepare.

The window opening 27 of the window opening frame portion 26 and the door opening 29 of the door opening frame portion 28 are respectively communicated with the rear opening 14 (see FIG. 2) of the rear opening frame portion 13 with the tailgate 15 closed.

As shown in FIG. 4, the outer panel 35 has an outer partition portion (plate-shaped portion) 36 that is located behind the inner panel 34 and that forms the outer surface of the partition frame 31.
The inner panel 34 has an inner partition portion 34 a that forms the inner surface of the partition frame 31.
The partition frame 31 is formed by overlapping an outer partition portion 36, an inner partition portion 34a, and a reinforcing member 37. By providing the reinforcing member 37 on the partition frame 31, the partition frame 31 is reinforced by the reinforcing member 37.

Therefore, the partition frame 31 ensures the rigidity of the window opening frame portion 26 and the door opening frame portion 28. A gate window glass 17 is provided on the window opening frame portion 26 from the rear of the vehicle body. A gate decoration member 18 is provided on the outer panel 35 below the window opening frame 26 from the rear of the vehicle body.
Further, the sub door 20 is supported on the partition frame 31 of the gate body 16.

  The sub door 20 includes a door main body 42 (see also FIG. 7) rotatably supported on the partition frame 31 via upper and lower door hinges 41, and a door window glass 43 provided in the upper half of the door main body 42. The door decoration member 44 is provided below the door window glass 43 (that is, the lower half of the door main body 42).

  As shown in FIG. 5, when the sub door 20 is opened in the horizontal direction (arrow A direction), the door opening 29 of the vehicle body 11 (rear portion 12) is opened. On the other hand, when the sub door 20 is closed, the door opening 29 is closed.

Here, as shown in FIG. 1, with the tailgate 15 closed and the subdoor 20 closed, the lower end 20 a of the subdoor 20 is disposed at substantially the same height as the lower end 15 a of the tailgate 15. Is done. Since the lower end 20a of the sub door 20 can be lowered to the lower end 15a of the tailgate 15, the lower frame 28b (see FIG. 5) of the door opening frame portion 28 can be lowered.
That is, as shown in FIG. 5, the door opening 29 can be expanded downward. Thereby, a passenger | crew can get on and off smoothly from the door opening 29, and a passenger | crew's boarding / alighting property can be improved.

Further, as shown in FIGS. 2 and 6, the outer surface 18a of the gate decoration member 18 and the outer surface 44a of the door decoration member 44 are substantially flush with each other in the vehicle front-rear direction (when the sub door 20 is closed). (See also FIG. 7).
Further, in a state where the sub door 20 is closed, the outer surface 17a of the gate window glass 17 and the outer surface 43a of the door window glass 43 are formed on substantially the same plane (substantially flush) in the vehicle body front-rear direction.

An outer surface 19 of the tailgate 15 is formed by the outer surface 18 a of the gate decoration member 18 and the outer surface 17 a of the gate window glass 17. Further, an outer surface 45 of the sub door 20 is formed by the outer surface 44 a of the door decoration member 44 and the outer surface 43 a of the door window glass 43.
The outer surface 19 of the tailgate 15 and the outer surface 45 of the sub door 20 are formed on substantially the same surface (substantially flush) in the longitudinal direction of the vehicle body.
The outer surface 19 of the tailgate 15 and the outer surface 45 of the auxiliary door 20 form the entire outer surface 47 of the tailgate 15.

Here, as shown in FIG. 3, the gate body 16 is formed in a curved shape so as to bulge toward the outside 23 in the vehicle width direction.
The gate main body 16 is provided with a gate window glass 17 and a gate decoration member (decoration member) 18, and the gate main body 16 is provided with a sub door 20 (a door window glass 43 and a door decoration member 44).

As shown in FIG. 2, the entire outer surface 47 of the tailgate 15 is in the vehicle width direction center 47a of the entire outer surface 47 (or the vehicle width direction including the vehicle width direction center 47a) with the tailgate 15 closed. (Near the center 47a) is located most rearward of the vehicle body.
Hereinafter, the “vehicle width direction center 47a” or “the vicinity of the vehicle width direction center 47a including the vehicle width direction center 47a” will be described as the vehicle width direction center 47a for the sake of convenience in understanding the configuration. To do.
Further, in a state in which the tailgate 15 is closed, the entire outer surface 47 is gradually positioned in front of the vehicle body from the vehicle width direction center 47a toward the left and right side portions (vehicle width end portions) 47b and 47c.
The vehicle width direction center 47 a is located on the center line 49 of the tailgate 15.

As shown in FIG. 7, there is a predetermined gap between the gate side edge 19 a on the sub door 20 side of the outer surface 19 of the tail gate 15 and the door side edge 45 a on the tail gate 15 side of the outer surface 45 of the sub door 20. A separation portion 51 is provided that is separated at a distance L1.
The separation portion 51 is provided at an offset position 47d that is offset (shifted) by a distance L2 from the vehicle width direction center 47a to the right side in the vehicle width direction. Further, the separation portion 51 is disposed so as to overlap the rear of the vehicle body from the outer partition portion 36 of the partition frame 31.
In other words, the outer partition portion 36 is disposed in front of the vehicle body from the separation portion 51 and at a position overlapping the separation portion 51.

  Therefore, as shown in FIG. 2, when the tailgate 15 is opened in the rain, water accumulates in the outer partition part 36 (see FIG. 8) through the separation part 51. When the tail gate 15 is closed, the accumulated water is guided along the outer partition portion 36 to the lower side of the tail gate 15, and it is considered that the water splashes vigorously from the lower end 15 a of the tail gate 15.

  Therefore, as shown in FIGS. 7 and 8, the convex portion 54 is protruded from the outer partition portion 36 toward the rear of the vehicle body. The convex portion 54 is provided in the vicinity of the lower end (lower end of the tailgate) 36a of the outer partition portion 36, and protrudes from the outer partition portion 36 toward the rear of the vehicle body.

Specifically, as shown in FIG. 9, the outer partition portion 36 is formed so as to be recessed toward the inner panel 34 with respect to the outer panel 35. Therefore, a stepped portion 53 (see also FIG. 7) is formed in an inclined shape between the outer partition portion 36 and the outer panel 35.
The step portion 53 is formed in an inclined manner with a downward slope from the outer panel 35 toward the outer side 36 c of the outer partition portion 36.

A convex portion 54 is provided in the vicinity (upper side) of the lower end 36 a of the outer partition portion 36.
The convex portion 54 is connected to an upper edge portion 55 that forms the upper edge of the convex portion 54, an upper inclined portion (inclined portion) 56 formed below the upper edge portion 55, and a lower end 56 a of the upper inclined portion 56. The top surface portion 57, the side inclined portion 58 connected to the inner end 57 a of the top surface portion 57, and the lower inclined portion 59 connected to the lower end 57 b of the top surface portion 57.

  The upper edge portion 55 is located at the same height in the up-down direction in the entire region L3 in the vehicle width direction. That is, the upper edge 55 extends in parallel to the lower edge 36b of the lower end 36a of the outer partition 36.

  As shown in FIG. 10, the upper inclined portion 56 is formed so as to be smoothly inclined from the front of the vehicle body to the rear of the vehicle body as it goes downward from the upper edge portion 55 with the upper edge portion 55 as a base point. In other words, the upper inclined portion 56 is formed so as to be smoothly inclined in a direction away from the inner partition portion 34a as it goes from the upper edge portion 55 to the lower end 36a.

The top surface portion 57 has a substantially rectangular shape with a full width L4 in the vehicle width direction and is formed in a flat shape, and the outer end 57c is connected to the step portion 53 (see also FIG. 7). The full width L4 of the top surface portion 57 in the vehicle width direction is smaller than the entire width L3 of the upper edge portion 55 in the vehicle width direction.
The top surface portion 57 is formed in a state of being recessed toward the inner partition portion 34a with respect to the outer panel 35, and an attachment hole 61 (see FIG. 9) is opened substantially at the center. The gate decoration member 18 is fixed to the top surface portion 57 using the mounting hole 61.
That is, the top surface portion 57 is also used as an attachment portion for attaching the gate decoration member 18.

Specifically, as shown in FIGS. 7 and 11, the head portion of the clip 64 is attached to the attachment portion 63 of the gate decoration member 18. The locking portion 64a of the clip 64 is locked to the mounting hole 61 (see also FIG. 9) of the top surface portion 57 as indicated by an arrow B. Therefore, the gate decoration member 18 is locked (fixed) to the top surface portion 57 via the clip 64.
Thereby, since it is not necessary to provide the attachment part which attaches the gate decoration member 18 separately, the number of parts can be suppressed and the structure can be simplified.

As shown in FIGS. 9 and 12, the side inclined portion 58 is inclined downward from the inner end 57 a of the top surface portion 57 toward the outer partition portion 36.
Here, the full width L4 of the top surface portion 57 in the vehicle width direction is suppressed to be smaller than the entire width L3 of the upper edge portion 55 in the vehicle width direction. Therefore, the side inclined portion 58 can be separated from the sub door 20 side. Thereby, when forming the subdoor 20 (especially the door main body 42 (refer FIG. 7)), the freedom degree of design can be raised.

As shown in FIGS. 9 and 10, the lower inclined portion 59 is inclined downward from the lower end 57 b of the top surface portion 57 toward the lower end 36 a of the outer partition portion 36.
Therefore, the lower inclined portion 59 can be separated from the lower end 18 b side of the gate decoration member 18. Thereby, when forming the gate decoration member 18, the freedom degree of design can be raised and the designability of the gate decoration member 18 can be improved.

Next, the reason why the convex portion 54 is provided in the vicinity of the lower end 36a of the outer partition portion 36 will be described in detail.
That is, when the tailgate 15 is opened in the rain, water accumulates in the outer partition portion 36 via the separation portion 51 (see FIG. 2). When the tailgate 15 is closed, the water accumulated in the outer partition 36 is guided along the outer partition 36 below the tailgate 15.

  Therefore, a convex portion 54 is provided in the vicinity of the lower end 36 a of the outer partition portion 36. Therefore, when the tailgate 15 is closed in a state where water has accumulated in the outer partition portion 36, water accumulated in the outer partition portion 36 above the convex portion 54 can be guided to the convex portion. That is, most of the water accumulated in the outer partition part 36 can be guided to the convex part.

  The water guided to the outer partitioning portion 36 is moderately flowed by the convex portion 54, and the flow is gentle. Therefore, it is possible to prevent most of the water accumulated in the outer partition portion 36 from splashing vigorously from the lower end 15a of the tailgate 15. Thereby, it is possible to prevent water from falling on the operator who closes the tailgate 15.

Further, the upper edge portion 55 of the convex portion 54 is positioned at the same height in the vertical direction in the entire region L3 in the vehicle width direction. Therefore, the water (rain water) that has flowed to the upper edge portion 55 of the convex portion 54 can be uniformly guided from the upper edge portion 55 to the upper inclined portion 56.
Further, the upper inclined portion 56 is smoothly inclined backward from the upper edge portion 55 of the convex portion 54 toward the rear of the vehicle body. Therefore, the water (rain water) that has reached the upper inclined portion 56 can be uniformly guided downward by the upper inclined portion 56 without stagnation.
Thereby, the water (rain water) collected by the outer partition part 36 can be drained uniformly from the lower end of the tailgate 15, and a favorable drainage state can be ensured.

In addition, the top surface portion 57 is connected to the lower end 56a of the upper inclined portion 56, and the top surface portion 57 is formed in a planar shape. Therefore, it is possible to prevent the water flow guided from the upper inclined portion 56 to the top surface portion 57 from being obstructed by the top surface portion 57.
Thereby, the favorable drainage state of the water (rain water) collected by the outer partition part 36 is securable.

As shown in FIG. 2, the center 47a in the vehicle width direction of the tailgate 15 (the entire outer surface 47) is located at the rearmost position of the vehicle body, and the left and right side portions 47b and 47c of the outer surface 47 extend from the vehicle width direction center 47a to the vehicle body. It is gradually moving forward.
Therefore, in the state where the tailgate 15 is opened, the center 47a in the vehicle width direction of the entire outer surface 47 is disposed at the highest position. As a result, rainwater falling on the tailgate 15 is guided from the center 47a in the vehicle width direction toward the left and right side portions 47a and 47b.

Here, the separation portion 51 is provided at an offset position 47d that is offset by a distance L2 from the vehicle width direction center 47a to the vehicle width direction right side. Therefore, a large amount of rainwater falling on the tailgate 15 can be guided from the vehicle width direction center 47a to the separating portion 51 and stored in the outer partition portion 36.
Thereby, it is possible to efficiently suppress the momentum of a large amount of rainwater that has fallen on the tailgate 15 so as to cause a gentle flow at the convex portion 54 (see FIG. 9).

By the way, as shown in FIGS. 8 and 10, in the sub door 20, the inner end 42 a of the door main body 42 in the vehicle width direction rotates to the partition frame 31 via the upper and lower door hinges 41 (see FIG. 1 for the upper door hinge 41). It is supported freely.
In the lower door hinge 41, a base hinge 71 is attached to the outer partition portion 36 with bolts 72 and nuts 73, and a rotating hinge 74 is attached to the inner end 42a in the vehicle width direction with bolts 75 and nuts.
A rotation hinge 74 is supported by the base hinge 71 via a support pin 76 so as to be rotatable.

The base hinge 71 is provided adjacent to the upper part of the outer partition part 36 above the convex part 54. Specifically, the outer partition portion 36 and the reinforcing member 37 of the outer partition portion 36 are attached with bolts 72 and nuts 73.
In this state, the protruding piece 71 a of the base hinge 71 is provided adjacent to the upper portion of the convex portion 54. The protruding piece 71a protrudes from the outer partitioning portion 36 toward the rear of the vehicle body in the same manner as the protruding portion 54 by the thickness of the plate.

Thereby, when the tailgate 15 is closed, the water accumulated in the outer partitioning portion 36 above the protruding piece 71a can be guided to the protruding piece 71a. The guided water is moderately flowed by the projecting piece 71a.
In the water suppressed to a gentle flow, the momentum of the flow is further suppressed by the convex portion 54, and it is possible to better prevent water from falling on the operator who closes the tailgate 15.

  The upper door hinge 41 is the same member as the lower door hinge 41, and the description of the upper door hinge 41 is omitted.
