  By the way, the beltline outer reinforcement and the beltline inner reinforcement may be provided on the beltline portion of the vehicle side door so as to overlap the door outside handle base (hinge bracket) when viewed from the outside in the vehicle width direction. is there. In this case, there are concerns about the following.

  That is, when the door outside handle base is displaced inward in the vehicle width direction at the time of a side collision, the rear side in the vehicle front-rear direction of the beltline outer reinforcement is folded by the door outside handle base, and the folded portion of the beltline outer reinforcement is There is a possibility that the vehicle longitudinal direction rear side of the beltline inner reinforcement may be folded. When the rear side in the vehicle longitudinal direction of the beltline inner reinforcement is folded in this way, the door inner panel is pressed inward in the vehicle width direction by the folded portion of the beltline inner reinforcement, and the rear side in the vehicle longitudinal direction of the door inner panel is There is a possibility that the protrusion amount (displacement amount) inward in the vehicle width direction becomes large. Therefore, it is necessary to reinforce the belt line part of the vehicle side door.

  In consideration of the above-described facts, the present invention has an object to provide a vehicle side door structure that can reduce the amount of protrusion of the door inner panel to the vehicle width direction inner side on the rear side in the vehicle longitudinal direction at the time of a side collision. To do.

The vehicle side door structure according to claim 1 is arranged so as to be opposed to the door outer panel in the vehicle width direction on the inner side in the vehicle width direction of the door outer panel. A door inner panel, a belt line outer reinforcement provided along a belt line portion of the door outer panel on the inner side in the vehicle width direction of the door outer panel, and the belt line outer reinforcement between the door inner panel and the door inner panel. A beltline inner reinforcement provided along a beltline portion of the door inner panel, a door lock device provided between the door outer panel and the door inner panel, and restraining the vehicle side door to the vehicle body; Vehicle width on the rear side in the vehicle front-rear direction of the door outer panel A door outside handle which is disposed outside and connected to the door lock device and is rotated to release the restraint by the door lock device; and a vehicle inside the vehicle outer side in the vehicle front-rear direction rear side of the door outer panel A front-rear direction is attached as a longitudinal direction, and the door outside handle is rotatably supported, and is wrapped with the door lock device without being wrapped with the beltline outer reinforcement as viewed from the vehicle width direction outside . In addition, the vehicle front-rear direction front end includes a door outside handle base that wraps with the beltline inner reinforcement .

  According to the vehicle side door structure of the first aspect, the door outside handle base does not wrap with the beltline outer reinforcement as viewed from the outside in the vehicle width direction. Thereby, even if the door outside handle base is displaced inward in the vehicle width direction due to a side collision, the door outside handle base is prevented from contacting the beltline outer reinforcement. Accordingly, folding of the beltline outer reinforcement on the rear side in the vehicle front-rear direction is suppressed. As a result, the folding of the beltline outer reinforcement due to the folding of the beltline outer reinforcement on the rear side in the vehicle front-rear direction is suppressed.

  On the other hand, the door outside handle base is wrapped with a door lock device that restrains the vehicle side door to the vehicle body when viewed from the outside in the vehicle width direction. As a result, when the door outside handle base is displaced inward in the vehicle width direction due to a side collision, the door outside handle base contacts the door lock device, and the side collision load acting on the door outside handle base is Since it is transmitted to the vehicle body via the device, the displacement of the door outside handle base inward in the vehicle width direction is limited. As a result, since the contact of the door outside handle base with the beltline inner reinforcement is suppressed, the folding of the beltline inner reinforcement on the rear side in the vehicle front-rear direction is suppressed.

  As described above, in the vehicle side door structure according to the present invention, in the case of a side collision, the outside hand base does not contact the beltline outer reinforcement but contacts the door lock device. The folding at the rear side in the direction is suppressed, and the contact of the door outside handle base with the rear side in the vehicle front-rear direction of the beltline inner reinforcement is suppressed. Therefore, the protrusion amount of the door inner panel to the inner side in the vehicle width direction on the rear side in the vehicle longitudinal direction is reduced.

  The vehicle side door structure according to claim 2 is the vehicle side door structure according to claim 1, wherein the door outside handle base is at least the door outside handle when viewed from the outside in the vehicle width direction. It wraps with the said door lock apparatus ranging from the edge part of the vehicle longitudinal direction rear side of a base to the center part of the vehicle longitudinal direction.

  According to the vehicle side door structure according to claim 2, when viewed from the vehicle width direction outer side, the door extends at least from the rear end in the vehicle front-rear direction of the door outside handle base to the center in the vehicle front-rear direction. By wrapping the outside handle base with the door lock device, when the door outside handle base is displaced inward in the vehicle width direction due to a side collision, the center portion of the door outside handle base in the vehicle longitudinal direction is the door lock device. To touch. That is, when the door outside handle base is displaced inward in the vehicle width direction due to a side collision, the center portion of the door outside handle base in the vehicle front-rear direction is supported by the door lock device. Therefore, the amount of displacement of the door outside handle base inward in the vehicle width direction is reduced compared with the case where only the rear end portion of the door outside handle base in the vehicle longitudinal direction contacts the door lock device at the time of a side collision. The

  The vehicle side door structure according to claim 3 is the vehicle side door structure according to claim 1 or 2, wherein the vehicle side door structure is provided between the door outside handle base and the door lock device. A door glass elevating rail that extends in the direction and supports the door glass so that it can be raised and lowered is provided.

  According to the vehicle side door structure according to claim 3, the door glass lift rail that supports the door glass so as to be movable up and down is provided between the door outside handle base and the door lock device. When the outside handle base is displaced inward in the vehicle width direction, the door outside handle base comes into contact with the door glass elevating rail before the door lock device. Thereby, when the door glass elevating rail is bent and deformed, the side collision energy input to the door outside handle base is absorbed. Thereafter, when the door outside handle base is further displaced inward in the vehicle width direction, the door outside handle base comes into contact with the door lock device, and the displacement inward in the vehicle width direction is limited. Therefore, the amount of displacement of the door outside handle base inward in the vehicle width direction is reduced as compared with a configuration in which the door glass lifting rail is not provided between the door outside handle base and the door lock device.

The vehicle side door structure according to claim 4 is the vehicle side door structure according to any one of claims 1 to 3, wherein the beltline inner reinforcement is provided along a vehicle front-rear direction. A bent portion that extends and is convexly bent outward in the vehicle width direction is formed so that the end portion of the door outside handle base does not wrap with the bent portion when viewed from the outside in the vehicle width direction. It extends from the door lock device to the front side in the vehicle longitudinal direction.

  According to the side door structure for a vehicle according to claim 4, when viewed from the outside in the vehicle width direction, the front end portion of the door outside handle base in the front-rear direction of the vehicle has a bent portion and a lap formed in the beltline inner reinforcement. Not done. Thus, for example, when the door outside handle base is displaced inward in the vehicle width direction due to a side collision, the front end portion of the door outside handle base in the vehicle front-rear direction contacts the bent portion of the beltline inner reinforcement. Is suppressed. Therefore, compared to the configuration in which the front end in the vehicle longitudinal direction of the door outside handle base is in contact with the bent portion of the belt line inner reinforcement at the time of a side collision, the folding of the belt line inner reinforcement on the rear side in the longitudinal direction of the vehicle. Therefore, the amount of protrusion of the door inner panel to the inside in the vehicle width direction on the rear side in the vehicle front-rear direction is reduced.

  As described above, the vehicle side door structure according to the present invention can reduce the amount of protrusion of the door inner panel to the inner side in the vehicle width direction on the rear side in the vehicle front-rear direction when a side collision occurs.

Thus, when the occupant rotates the door handle 64 about the rotation axis outward in the vehicle width direction, the door lock device 50 is actuated by the release lever connected to the door handle 64, and the restraint of the side door 14 with respect to the vehicle body 12 is performed. It is to be released.

  Here, as shown in FIG. 4, when the side door 14 is viewed from the outside in the vehicle width direction, the door handle base 62 is positioned below the outer reinforcement 30 in the vehicle vertical direction. That is, the door handle base 62 is arranged so as not to wrap with the outer reinforcement 30 when the side door 14 is viewed from the outside in the vehicle width direction. Thereby, as shown by a two-dot chain line in FIGS. 2 and 3, when the door handle base 62 is displaced inward in the vehicle width direction due to a side collision, the door handle base 62 is prevented from coming into contact with the outer reinforcement 30. It has become.

  As shown in FIG. 4, when the side door 14 is viewed from the outside in the vehicle width direction, the door handle base 62 has an end portion on the rear side in the vehicle front-rear direction (hereinafter simply referred to as “rear end portion 62R”). To the center in the vehicle front-rear direction (hereinafter simply referred to as “center 62M”) so as to wrap with the door lock device 50. As a result, as shown by a two-dot chain line in FIG. 3, when the door handle base 62 is displaced inward in the vehicle width direction due to a side collision, the door handle base 62 comes into contact with the door lock device 50. .

  On the other hand, as shown in FIG. 4, when the side door 14 is viewed from the outside in the vehicle width direction, the end of the door handle base 62 on the front side in the vehicle front-rear direction (hereinafter simply referred to as “front end 62 </ b> F”) It extends from the locking device 50 to the front side in the vehicle longitudinal direction. The front end portion 62F of the door handle base 62 is located below the second bead portion 44 of the inner reinforcement 40 in the vehicle vertical direction when the side door 14 is viewed from the outside in the vehicle width direction. Accordingly, as indicated by a two-dot chain line in FIG. 2, when the front end portion 62F of the door handle base 62 is displaced inward in the vehicle width direction due to a side collision, the front end portion 62F becomes the second bead of the inner reinforcement 40. The portion 44 is not touched.

  Further, as shown in FIG. 3, between the door handle base 62 and the door lock device 50, a door glass that slidably supports the rear end of the door glass 20 (see FIG. 1) in the vehicle front-rear direction. A lifting rail rear 70B is arranged. The door glass elevating rail rear 70B is formed in a C-shaped cross section and is disposed along the vehicle vertical direction. Accordingly, when the door handle base 62 is displaced inward in the vehicle width direction due to a side collision, the door handle base 62 comes into contact with the door glass lifting rail rear 70 </ b> B before the door lock device 50.

  Next, the operation of this embodiment will be described.

  5 (A) and 5 (B) schematically show the rear side in the vehicle front-rear direction of the side door 14 to which the vehicle side door structure 10 according to this embodiment is applied. In FIGS. 5A and 5B, the illustration of the lock reinforcement 52 is omitted.

  As shown in FIG. 5A, when a side collision load F acts on the door outer panel 22 due to a side collision, the door outer panel 22 is deformed inward in the vehicle width direction, and the door handle base 62 attached to the door outer panel 22 is For example, as indicated by the two-dot difference line, the vehicle is displaced (translated) substantially inward in the vehicle width direction.

  Here, when the side door 14 is viewed from the outside in the vehicle width direction, the door handle base 62 is disposed below the outer reinforcement 30 in the vehicle vertical direction, and is not wrapped with the outer reinforcement 30. Thereby, even if the door handle base 62 is displaced inward in the vehicle width direction due to a side collision, the door handle base 62 is prevented from coming into contact with the rear side of the outer reinforcement 30 in the vehicle front-rear direction. Therefore, the folding of the outer reinforcement 30 on the rear side in the vehicle front-rear direction is suppressed. As a result, since the folding of the outer reinforcement 30 due to the folding of the outer reinforcement 30 at the rear side in the vehicle longitudinal direction is suppressed, the amount of protrusion of the door inner panel 24 to the inside in the vehicle width direction on the rear side in the vehicle longitudinal direction (Displacement amount) is reduced.

  On the other hand, when the side door 14 is viewed from the outside in the vehicle width direction, the door handle base 62 is wrapped with the door lock device 50 at least from the rear end portion 62R to the central portion 62M. Therefore, when the door handle base 62 is displaced (translated) inward in the vehicle width direction due to a side collision, the door handle base 62 contacts the door lock device 50.

  Here, the door lock device 50 is connected to the center pillar 28 (see FIG. 1) constituting the skeleton of the vehicle body 12 via a striker (not shown) at the closed position of the side door 14. Therefore, when the door handle base 62 comes into contact with the door lock device 50, the side impact load F applied to the door handle base 62 is transmitted to the center pillar 28 via the door lock device 50 and the striker. That is, the door handle base 62 is supported by the center pillar 28 via the door lock device 50 and the striker. Thereby, the displacement of the door handle base 62 in the vehicle width direction is limited.

  In addition, when the side door 14 is viewed from the outside in the vehicle width direction, the center portion 62M of the door handle base 62 in the vehicle front-rear direction is wrapped with the door lock device 50, so that the center portion of the door handle base 62 is at the time of a side collision. 62M contacts the door lock device 50. Here, the center of gravity G of the door handle base 62 is generally located in the periphery of the central portion 62M in the vehicle front-rear direction. Therefore, the peripheral portion of the center of gravity G of the door handle base 62 is supported by the door lock device 50 at the time of a side collision. Thereby, for example, compared with the case where only the rear end portion 62R of the door handle base 62 contacts the door lock device 50 at the time of a side collision, the amount of displacement of the door handle base 62 in the vehicle width direction is reduced.

  Further, a door glass elevating rail rear 70 </ b> B is provided between the door handle base 62 and the door lock device 50. Therefore, when the door handle base 62 is displaced (translated) inward in the vehicle width direction due to a side collision, the door handle base 62 contacts the door glass lifting rail rear 70 </ b> B before the door lock device 50. Thereby, when the door glass lifting rail rear 70B is bent and deformed, the side collision energy input to the door handle base 62 is absorbed. Thereafter, when the door handle base 62 is further displaced inward in the vehicle width direction, the door handle base 62 comes into contact with the door lock device 50, and the displacement inward in the vehicle width direction is limited. Therefore, the amount of displacement of the door handle base 62 toward the inside in the vehicle width direction is reduced as compared with a configuration in which the door glass lifting rail rear 70B is not provided between the door handle base 62 and the door lock device 50.

  Thus, in the vehicle side door structure 10 according to the present invention, the door handle base 62 does not contact the outer reinforcement 30 but contacts the door lock device 50 at the time of a side collision. The folding at the rear side in the direction is suppressed, and the contact of the door handle base 62 with the rear side in the vehicle longitudinal direction of the inner reinforcement 40 is suppressed. Therefore, the amount of protrusion of the door inner panel 24 inward in the vehicle width direction on the rear side in the vehicle longitudinal direction is reduced.

  By the way, depending on the deformation mode of the door outer panel 22 at the time of a side collision, for example, as shown in FIG. 5B, the door handle base 62 is positioned on the vehicle width direction inner side with respect to the rear end portion 62R. May rotate to do. In this case, the rear end 62 </ b> R of the door handle base 62 may come into contact with the inner reinforcement 40. At this time, when the front end portion 62F of the door handle base 62 comes into contact with the first bead portion 42 or the second bead portion 44 of the inner reinforcement 40 where stress is easily concentrated, the rear side in the vehicle front-rear direction of the inner reinforcement 40 is easily broken. .

  As a countermeasure, in this embodiment, when the side door 14 is viewed from the outside in the vehicle width direction, the front end portion 62F of the door handle base 62 is disposed below the second bead portion 44 of the inner reinforcement 40 in the vehicle vertical direction. ing. Thereby, even if the door handle base 62 rotates as described above, the front end portion 62F of the door handle base 62 is prevented from contacting the first bead portion 42 and the second bead portion 44. Therefore, compared to the configuration in which the front end portion 62F of the door handle base 62 is in contact with the first bead portion 42 or the second bead portion 44 of the inner reinforcement 40 at the time of a side collision, the inner reinforcement 40 has a vehicle longitudinal direction rear side. Therefore, the amount of protrusion of the door inner panel 24 toward the inner side in the vehicle width direction on the rear side in the vehicle front-rear direction is reduced.

  Next, a modified example of the vehicle side door structure according to the embodiment will be described.

  In the above embodiment, the door handle base 62 is disposed below the outer reinforcement 30 in the vehicle vertical direction so that the door handle base 62 does not wrap with the outer reinforcement 30 when the side door 14 is viewed from the vehicle width direction outside. However, it is not limited to this. For example, a notch portion may be formed in the lower end portion of the outer reinforcement 30 so that the door handle base 62 does not wrap with the outer reinforcement 30 when the side door 14 is viewed from the outside in the vehicle width direction.

  In the above embodiment, when the side door 14 is viewed from the outside in the vehicle width direction, the center portion 62M of the door handle base 62 in the vehicle front-rear direction is wrapped with the door lock device 50. It is also possible to wrap the G position with the door lock device 50.

  Furthermore, a door glass lifting rail rear 70B may be disposed between the door handle base 62 and the door lock device 50 as necessary, and a door is not necessarily provided between the door handle base 62 and the door lock device 50. It is not necessary to arrange the glass lifting rail rear 70B.

  Furthermore, although the case where the vehicle side door structure 10 is applied to the front side door 14 has been described as an example in the above embodiment, the vehicle side door structure 10 can also be applied to a rear side door. When the vehicle side door structure 10 is applied to the rear side door, the rear pillar corresponds to the center pillar 28 in the above embodiment.

  As mentioned above, although one embodiment of the present invention was described, the present invention is not limited to such an embodiment, and one embodiment and various modifications may be used in combination as appropriate, and the gist of the present invention will be described. Of course, various embodiments can be implemented without departing from the scope.
