Description

  The present invention relates to a vehicle body side structure.

  In the side structure of the vehicle body, it is desirable to efficiently transmit the impact applied to the door to the pillar or the like. For example, Patent Document 1 describes a vehicle body side structure in which a protruding portion that overlaps with a main body pillar is provided on a door, and the protruding portion and the main body pillar are provided with engaging protrusions at the time of a side collision.

By the way, in order to transmit the load acting on the door to the vehicle body (pillar or the like) in a short time and to shorten the idling distance, it is preferable that these gaps are small. However, for example, if the engaging convex portion of Patent Document 1 is too close, the engaging convex portion interferes even when the door is opened and closed.
JP 2001-310663 A

  In view of the above facts, an object of the present invention is to obtain a vehicle body side structure capable of shortening the idling distance at the time of a side collision without impeding the opening and closing of the door body.

According to the first aspect of the present invention, the bracket main body provided on the door end surface on the mounting end side of the door main body rotatably attached to the vehicle body, and the vehicle width direction outer end surface of the body pillar of the vehicle body from the vehicle width direction outer side. And an engagement piece that is an opposing surface that inclines outward in the vehicle width direction from the vehicle front side toward the vehicle rear side, and the door body pivots when the door body is closed. A contact portion formed on the bracket body so as to be located at the same position or a rear position in the vehicle longitudinal direction with respect to the center , and the contact portion is a vehicle width of the bracket body when the bracket body is viewed from above. It is located on the inner side in the direction, is opposed to the facing surface in the vehicle width direction, and is inclined outward in the vehicle width direction from the vehicle front side toward the rear side .

In the present invention, the contact portion formed on the bracket main body is located on the inner side in the vehicle width direction of the bracket main body as viewed from above, and faces the facing surface of the engagement piece of the body pillar in the vehicle width direction. Therefore, when the attachment end side of the door main body moves to the center in the vehicle width direction at the time of a side collision, the contact portion formed on the bracket main body contacts the opposing surface of the engagement piece of the body pillar and transmits the load to the vehicle body. Here, the contact portion with respect to the rotation center of the door body in a closed state of the door body, are located in the longitudinal direction of the vehicle at the same position or rearward position. For this reason, in the operation | movement which rotates a door main body from a closed state to an open state, a contact part is spaced apart from a vehicle body. That is, since the contact portion does not interfere with the vehicle body when the door body is opened and closed, there is no hindrance to opening and closing. As a result, the contact portion can be arranged close to the vehicle body, and the free running distance at the time of a side collision can be shortened by making the contact portion approach. Moreover, the contact portion is inclined outward in the vehicle width direction from the vehicle front side toward the rear side .
Therefore, with the contact portion in contact with the opposing surface of the engagement piece of the body pillar , when the contact portion further moves inward in the vehicle width direction, a part of the load of the side collision acts in the direction along the contact portion, The load can be efficiently transmitted to the body pillar .

  According to a second aspect of the present invention, an impact beam disposed in the door body so as to extend in the vehicle front-rear direction, and a connecting member that connects the impact beam to the bracket body so as to transmit a load. It is characterized by having.

  Therefore, the side collision load first acts on the impact beam, so that deformation of the door body can be suppressed. Since this load is transmitted from the impact beam to the bracket body via the connecting member, the contact portion approaches and contacts the vehicle body, and the load can be transmitted to the vehicle body more efficiently.

  Since the present invention has the above-described configuration, it is possible to shorten the free running distance at the time of a side collision without impeding the opening and closing of the door body.

  FIG. 1 partially shows a vehicle body side structure 102 according to the first embodiment of the present invention. The vehicle body side structure 102 of the present embodiment is applied to a support end side of a door 104 that is rotatably supported with respect to the vehicle body around one end, and a body pillar 106 that forms a part of the vehicle body on the support end side. . FIG. 2 shows a state in which the door 104 is opened by being rotated in this way. In the drawings, the front of the vehicle is indicated by an arrow FR, the upper side is indicated by an arrow UP, and the outer side in the vehicle width direction is indicated by an arrow OUT.

  As can be seen from FIGS. 1 and 2, the door 104 has a door outer 108 and a door inner 110. The door outer 108 has a substantially flat plate shape, but the door inner 110 has a flat plate portion 110A located substantially in parallel to the door outer 108 on the inner side in the vehicle width direction than the door outer 108, and the door outer 108 from the flat plate portion 110A. The front wall portion 110B extends toward the end of the front wall portion, and the extended portion 110C extends further obliquely forward from the front wall portion 110B. The extension 110C partially overlaps the body pillar 106 when viewed in the vehicle width direction. The door outer 108 and the door inner 110 are joined to each other at the outer peripheral portion thereof to form a door main body 112.

  As shown in FIG. 3, a door hinge 114 is provided between the extending portion 110 </ b> C and the body pillar 106. By this door hinge 114, the door 104 can be rotated around a rotation center axis 114A.

  An impact beam 116 is disposed between the door outer 108 and the door inner 110. In this embodiment, the impact beam 116 is formed in a cylindrical shape or a rod shape from a material having a predetermined strength (rigidity), and its axial direction substantially coincides with the vehicle longitudinal direction (has at least a component in the vehicle longitudinal direction). Are arranged as follows.

  The tip of the impact beam 116 is attached to the door inner 110 by an impact beam extension 118. In the impact beam extension 118, joint portions 120 and 122 that are respectively joined to the extension portion 110C and the front wall portion 110B of the door inner 110 are set at an outer end portion and an inner end portion in the vehicle width direction. Further, a bulging portion 124 bulging obliquely outward in the vehicle width direction is formed between the joint portions 120 and 122 so as to be separated from the door inner 110. In the present embodiment, the bulging portion 124 has a substantially triangular shape when viewed from above, and an impact beam fixing portion 126 is formed in a portion substantially parallel to the door outer 108. The front end of the impact beam 116 is fixed to the impact beam fixing portion 126.

  A portion extending obliquely from the impact beam fixing portion 126 to the door inner 110 is a load transmission portion 128 capable of transmitting a load from the impact beam 116 to the door inner 110. The load transmitting portion 128 is formed in a direction from the impact beam fixing portion 126 toward the body pillar 106, and in particular, its shape is determined so that an extension line thereof is directed to the centroid C2 of the body pillar 106.

  As shown in FIGS. 1 and 2, the joint 120 of the impact beam extension 118 is attached to the extension 110 </ b> C of the door inner 110 by a bolt 138 and a nut 140. By 140, an engagement bracket 142 is attached to the outside of the door inner 110. That is, the door inner 110 is joined so as to be sandwiched between the engagement bracket 142 and the impact beam extension 118.

  As shown in detail in FIG. 4, the engagement bracket 142 is formed in a flat oblique cylindrical shape, and is attached to the door inner 110 with a bolt 138 and a nut 140 on a bottom surface 142B at one end in the axial direction. The surface opposite to the bottom surface is open.

  As shown in FIG. 1, the engagement bracket 142 has an inclined surface 144 whose surface positioned on the inner side in the vehicle width direction when viewed from above is inclined acutely with respect to the front-side extension line L <b> 2 of the impact beam 116. Has been. In the present invention, when the door 104 is closed, as shown in FIG. 3, the inclined surface 144 is located at the same position in the vehicle front-rear direction as the center axis 114A of the door hinge 114 (when viewed in the vehicle width direction, the inclined surface 144 Is positioned so that the inclined surface 144 is behind the rotation center axis 114A. In particular, in the present invention, the inclined surface 144 is positioned so as to overlap the rotation center shaft 114A in the vehicle front-rear direction.

  As shown in FIGS. 1 and 2, the body pillar 106 is provided with a side member 146 so as to surround the periphery when viewed from above, and from the outer end surface of the side member 146 in the vehicle width direction, An engagement piece 148 protrudes outward in the vehicle width direction. A surface on the vehicle front side of the engagement piece 148 is a facing surface 150 that faces the inclined surface 144 of the engagement bracket 142. Since the inclined surface 144 is inclined at an acute angle from the front-side extension line L2 of the impact beam 116 as described above, the vehicle is further moved with the inclined surface 144 in contact with the facing surface 150 as shown in FIG. When moving inward in the width direction, a force in the direction of arrow F <b> 1 acts on the inclined surface 144 from the facing surface 150.

  As shown in FIGS. 1 and 4, the engagement bracket 142 is connected to the front side of the vehicle from the inclined surface 144, and the projecting end 152 </ b> T is inclined in the direction opposite to the inclined surface 144. Is formed. In the present invention, since the engaging bracket 142 is formed in a flat cylindrical shape as described above, two reverse inclined flanges 152 are formed at an upper position and a lower position continuous from the inclined surface 144. And when the force to the vehicle width direction outer side acts on the inclined surface 144, the reverse inclination flange 152 has the effect | action which suppresses falling of the inclined surface 144 against this.

  A door weather 134 is attached to the door inner 110 at a position on the inner side in the vehicle width direction with respect to the engagement bracket 142. The door weather 134 is disposed so as to surround the outer periphery of the door main body 112, and is in close contact with the vehicle body (the body pillar 106 and the like) with the door 104 closed, so that foreign matter such as moisture and dust is inadvertently brought into the vehicle interior. Avoid intrusion. In particular, in the present invention, the joint portion 122 of the impact beam extension 118 also acts as the door weather mounting portion 136 of the door weather 134. Therefore, the door weather 134 is disposed at a position corresponding to the joint portion 122, and the joint portion 122 and the door weather 134 are joined so as to sandwich the door inner 110.

  As shown in FIG. 1, a door check 174 is disposed further inside than the door weather 134 in the vehicle width direction. The front end of the door check 174 is rotatably supported by a support member 176 attached to the body pillar 106, but the rear end of the door check 174 is held by a sliding member (not shown) It slides with respect to the door 104. The position from the front end of the door check 174 to the middle portion is inserted through an opening 110H formed in the door inner 110.

  A door check bracket 178 is disposed in the door 104. The door check bracket 178 has a sliding portion 180 on which the door check 174 is slid. When the door check 174 is slid on the sliding portion 180 when the door 104 is opened and closed, a predetermined resistance or A sense of moderation comes into play. Further, the impact beam extension 118 is formed with a joint portion 119 to which the door check bracket 178 is joined at a position on the inner side in the vehicle width direction. The joint portion 119 is also formed with an insertion hole 119H through which the door check 174 is inserted.

  As can be seen from FIGS. 1 and 2, in the present invention, the door check bracket 178 is connected to the joint 122 of the impact beam extension 118, and the impact beam extension 118 and the door check bracket 178 are integrally formed. ing.

  Next, the operation of this embodiment will be described.

  As shown in FIG. 1, the inclined surface 144 of the engagement bracket 142 is separated from the facing surface 150 of the engagement piece 148 in a normal state, that is, when no load is applied to the door 104 from the side. The inclined surface 144 is located at the same position in the vehicle front-rear direction as the rotation center axis 114A of the door hinge 114 (the inclined surface 144 overlaps the rotation center axis 114A when viewed in the vehicle width direction), or the inclined surface 144 is Since it is located behind the rotation center shaft 114A, when the door 104 is rotated as shown in FIG. 2, the movement locus of the inclined surface 144 does not enter the inside in the vehicle width direction. Therefore, in order to prevent contact and interference between the inclined surface 144 and the opposed surface 150 when the door 104 is rotated, it is not necessary to dispose the inclined surface 144 away from the opposed surface 150. The surface 144 is disposed close to the facing surface 150.

  Here, as shown in FIG. 5, a case where a load is applied to the door 104 from the side (hereinafter, this case is appropriately referred to as “side collision”) will be considered. This load acts on the engagement bracket 142 from the impact beam 116 via the impact beam extension 118, and the engagement bracket 142 moves inward in the vehicle width direction. Then, the inclined surface 144 is pressed against the facing surface 150. Here, as described above, in the present invention, since the inclined surface 144 is disposed close to the facing surface 150, the distance until the inclined surface 144 contacts the facing surface 150, that is, the so-called idle running distance is also shortened. Yes.

  The inclined surface 144 is inclined at an acute angle from the front-side extension line L2 of the impact beam 116. When the inclined surface 144 is further moved inward in the vehicle width direction in contact with the opposing surface 150, a component force of a side collision load is obtained. Receives force in the direction of arrow F1. For this reason, the impact beam 116 joined to the door 104 via the impact beam extension 118 is also pulled in the direction of the arrow F1. Thereby, the load from the impact beam 116 can be efficiently transmitted to the body pillar 106.

  Note that when the inclined surface 144 of the engagement bracket 142 is pressed against the opposing surface 150, the force in the direction of the arrow F1 acts on the inclined surface 144 from the opposing surface 150 as described above. As shown in FIG. The engagement bracket 142 of the present invention is provided with a reverse inclined flange 152, and acts so that the reverse inclined flange 152 prevents the inclined surface 144 from falling down by this force. That is, by using the side impact load, the load transmission from the impact beam 116 to the body pillar 106 can be performed more reliably.

  Further, in the present invention, the engagement bracket 142 is attached to the door inner 110 to be partially reinforced. In particular, the attachment portion of the engagement bracket 142 is also a portion to which the impact beam 116 is attached via the impact beam extension 118, but this portion is effectively reinforced.

  Further, as can be seen from FIG. 4, the engagement bracket 142 of the present invention is located above the attachment portion of the door hinge 114 to the door 104, and the inclined surface 144 has water to the outside of the door 104. It is designed to guide the flow. Therefore, it is possible to prevent the door hinge 114 and the door weather 134 from being wetted.

  In addition, according to the present invention, since the engagement bracket 142 is attached to the door inner 110, the moment of inertia around the door hinge 114 of the door 104 is increased. For this reason, the so-called closing property (moderation feeling when closing) of the door 104 can be improved.

  Further, as can be seen from FIG. 2, when the door 104 is opened, the inclined surface 144 of the engagement bracket 142 partially hides the gap between the body pillar 106 and the door inner 110. Thereby, the appearance around the door hinge 114 is improved.

  FIG. 7 shows a vehicle body side structure 202 according to the second embodiment of the present invention. In the second embodiment, an extended portion 206 that extends further to the front side of the vehicle than the first embodiment is formed from the inclined surface 144 of the engagement bracket 204. As a result, the amount of overlap L between the facing surface 150 and the engagement bracket 204 (the inclined surface 144 and the extending portion 206) when viewed in the vehicle width direction is increased, so that the load from the impact beam 116 can be more effectively reduced. Can be transmitted to the body pillar 106. Since the second embodiment has the same configuration as that of the first embodiment except for the above, the same components, members, and the like are denoted by the same reference numerals and detailed description thereof is omitted.

  FIG. 8A shows a vehicle body side structure 302 according to the third embodiment of the present invention. In the third embodiment, the configuration of the body pillar is different from that of the first embodiment. Other than that, for example, the configuration of the door 104 is the same as that of the first embodiment. The same reference numerals are assigned and detailed description is omitted.

  In the second embodiment, the engagement piece 148 (see FIG. 1) is not formed on the side member 306 of the body pillar 304, but a body pillar bracket 308 is attached instead. As shown in detail in FIG. 8B, the end surface of the body pillar bracket 308 (the upper surface and the lower surface when attached to the body pillar 304) is formed in a substantially “C” shape. An engaging portion 310 having the same action as that of the combined piece 148 and a guide portion 312 facing the engaging portion 310 are configured. And in 3rd Embodiment, the body pillar bracket 308 is attached to the side member 306 of the body pillar 304 so that the engaging part 310 may become a substantially the same position as the engagement piece 148 of 1st Embodiment. In the attached state, the guide portion 312 is located on the vehicle front side with respect to the engaging portion 310.

  In the third embodiment having such a configuration, the same effect as in the first embodiment is obtained, but in addition, the movement of the inclined surface 144 of the engagement bracket 142 during the impact action from the side (the engagement portion) The movement of the 310 approaching the facing surface 150 can be guided by the guide portion 312. Thereby, the load from the impact beam 116 can be efficiently transmitted by the body pillar 106.

  Further, in the third embodiment, it is not necessary to form the engaging piece 148 (see FIG. 1) by the side member 146, so that the formability of the side member 146, for example, by press molding is improved.

  Moreover, in the third embodiment, the body pillar 106 is reinforced by the body pillar bracket 308, so that the load acting on the impact beam 116 or the body pillar 106 can be received more reliably.

  FIG. 9 shows a vehicle body side structure 402 according to the fourth embodiment of the present invention. In the third embodiment, the configuration of the engagement bracket and the side member of the pillar is different from that of the first embodiment, but the other components are substantially the same as those of the first embodiment. The members are denoted by the same reference numerals, and detailed description thereof is omitted.

  The engagement bracket 404 of the fourth embodiment is formed in a substantially “C” shape when viewed from above, and in addition to the inclined surface 406 having the same action as the inclined surface 144 of the first embodiment, this inclined A second inclined surface 408 is formed that is located in front of the surface 406 and outside in the vehicle width direction. Further, a second engagement piece 410 that overlaps the second inclined surface 408 when viewed in the vehicle width direction is also formed on the side member 146 of the body pillar 106. The surface of the second engagement piece 410 on the vehicle front side is a second facing surface 412 that faces the second inclined surface 408.

  In the fourth embodiment having such a configuration, when a load is applied to the door 104 from the side, not only the inclined surface 406 is pressed against the opposing surface 150 but also the second inclined surface 408 is the second opposing surface. 412 is pressed. Therefore, the load from the impact beam 116 can be transmitted to the body pillar 106 more efficiently.

  FIG. 10 shows a vehicle body side structure 502 according to the fifth embodiment of the present invention. Also in the fifth embodiment, the configuration of the engagement bracket and the side member of the pillar is different from that of the first embodiment, but the other components are substantially the same as those of the first embodiment. The members are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the engagement bracket 504 of the fifth embodiment, an inclined surface 506 and a second inclined surface 508 that are substantially the same as the inclined surface 406 and the second inclined surface 408 of the fourth embodiment are formed. A multi-stage engaging portion 510 having an end surface formed in a wave shape when viewed from above is formed. Moreover, the 2nd opposing surface 512 similar to the 2nd opposing surface 412 of 4th Embodiment is provided.

  Therefore, in the fifth embodiment, when a load is applied to the door 104 from the side, the inclined surface 406 is pressed against the facing surface 150. As the pressing proceeds, the multistage engaging portion 510 is moved to the second facing surface 512. Are sequentially pressed and engaged. Thereby, the load from the impact beam 116 can be efficiently transmitted to the body pillar 106 in multiple stages.

  In each of the above embodiments, an example in which the door inner 110 is joined by the engagement bracket and the impact beam extension 118 is described as an example. However, other members can be joined to these. is there. For example, as shown in FIG. 11, a part of the mirror bracket 188 may be joined so as to be sandwiched between the engagement bracket 142 and the impact beam extension 118. Further, as shown in FIG. 12, a part of the glass frame 170 is extended between the engagement bracket 142 and the impact beam extension 118 (the extended part is indicated by reference numeral 170E) and joined so as to be sandwiched between them. Also good.

  In any structure, when a load is applied to the side surface of the door 104, the load applied to the glass frame 170 and the like can be relaxed by the engagement bracket 142 and efficiently transmitted to the body pillar 106. Further, since the door inner 110 is reinforced by these members (and further by the engagement bracket 142), the door inner 110 can be made thinner and lighter.

  In addition, the structure for joining the impact beam 116 to the door inner 110 is not limited to the above. For example, as shown in FIG. 13, the impact beam 116 is extended to the vehicle front side so as to reach the door inner 110 (strictly, the joint 120 of the impact beam extension 118), and is engaged with the tip portion of the impact beam 116. The bracket 142 may be joined so as to sandwich the joint 120 between the door inner 110 and the impact beam extension 118.

  Furthermore, as shown in FIG. 14, the tip of the impact beam 116 extends so as to penetrate the door inner 110, and the tip portion also serves as the engagement bracket 142 (the engagement bracket 142 is connected to the impact beam 116 and the impact beam 116). The shape may be integrated.

In any configuration, since the door inner 110 having a large area is sandwiched between the impact beam extension 118 and the engagement bracket 142, the joint point between the impact beam 116 and the door inner 110 when the door 104 is opened and closed. The vehicle longitudinal force acting on the vehicle can be distributed over a wide area. Since high strength is not required for the door inner 110, it is possible to reduce the plate thickness and reduce the weight. In particular, even when a material having a low Young's modulus (aluminum, magnesium, resin, etc.) is used as the door inner 110, it is not necessary to increase the plate thickness .
In general, the impact beam 116 often has a predetermined weight from the viewpoint of maintaining the strength, but in the above invention, the rigidity of the mounting portion of the impact beam 116 is also high. For this reason, the vibration transmitted to the internal components of the door 104 from the impact beam 116 caused by opening and closing of the door 104 can be suppressed. For example, it is possible to suppress a closing sound of the door 104, an abnormal sound during traveling of the vehicle, and the like.

  The shape of the engagement bracket is not limited to the above. For example, as shown in FIG. 15, the door inner 110 is often attached with a wire harness attachment member 162 in which a hole for inserting the wire harness is formed, but the engagement bracket 142 and the wire harness attachment member 162 are attached. And may be integrated. Further, as shown in FIG. 16, the engagement bracket 142 and the door hinge 114 may be integrated. In the structure shown in FIG. 15 or FIG. 16, the inclined surface 144 of the engagement bracket 142 is enlarged so as to extend substantially in the vertical direction, so that the load from the impact beam 116 is more reliably applied to the body pillar 106. It is possible to communicate.

  Further, according to the present invention, the mass of the three components of the impact beam 116, the impact beam extension 118, and the engagement bracket 142 is concentrated in the vicinity of the front end of the door 104. The minute torsional elastic deformation can be stabilized, and the closing property of the door 104 can be improved.

  Furthermore, when the present invention is applied to the lower end portion of the door 104 or in the vicinity thereof, the glass 172 having a large mass is supported below, and a weight balance can be achieved. Further, the impact beam 116, the impact beam extension 118, and the engagement bracket 142 are arranged in the target direction of the door lock. By these, the closing property of the door 104 can further be improved.

  The impact beam extension 118 and the engagement bracket 142 can be joined not only by the bolt 138 and the nut 140 described above, but also by welding, riveting, adhesion, insertion, or the like.

  The engagement bracket according to the present invention can be arranged not only on the door hinge 114 side of the door 104 but also on the rotation end side of the door 104 as a shape applicable to the rotation end side (rear side). For example, as shown in FIG. 17B, an engagement bracket 192 whose end faces (upper surface and lower surface) are triangular is used, and the engagement bracket 192 is connected to the door 104 as shown in FIG. You may attach to the door inner 110 of the rotation end side. In this configuration, similarly to the configuration provided on the door hinge 114 side, the inclined surface 194 of the engagement bracket 192 can be disposed close to the opposing surface 198 of the body pillar 196, and the free running distance when a load acts on the side surface can be increased. Can be shortened.

  In addition, in this configuration, it is not necessary to form a surface that protrudes greatly from the door 104 in order to shorten the idling distance. For this reason, the passenger can get on and off the vehicle more smoothly.

  Further, in this configuration, as can be seen from FIG. 17A, the door inner 110 can be joined with a part of the lock reinforcement 186 and the engagement bracket 142 interposed therebetween. Furthermore, although not shown, the door inner 110 may be sandwiched between the belt line reinforcement or the hinge retainer and the engagement bracket 142 so as to be joined. Even in these structures, when a load acts on the side surface of the door 104, the load applied to the lock reinforcement 186, the beltline reinforcement, or the hinge retainer is relieved by the engagement bracket 142, and can be efficiently transmitted to the body pillar 106. it can. Further, since the door inner 110 is reinforced by these members (and further by the engagement bracket 142), the door inner 110 can be made thinner and lighter.
