Description

  The present invention relates to a vehicle body side structure.

  As for the side structure of the vehicle body, in particular, the door structure, there is one in which, as shown in Patent Document 1, for example, an operator is given a moderate feeling of moderation when opening and closing the door by door check. A sliding member on which a door check (a check arm for flying) slides is joined to the door body by a bracket or the like.

By the way, in an actual vehicle side structure, a sliding force acts on the bracket when the door body is opened and closed, that is, when the door check slides, and a load in the peeling direction (an oblique direction) acts on the joint surface to the door body. The durability of the door check bracket may decrease.
Japanese Patent No. 3434620

  In view of the above fact, the present invention provides a vehicle body side structure capable of improving the durability of the door check bracket by suppressing the separation of the joint portion of the door check bracket caused by the sliding of the door check. Let it be an issue.

  According to the first aspect of the present invention, the vehicle check direction between the door check disposed between the vehicle body and the door body rotatable with respect to the vehicle body, and the outer panel and the inner panel constituting the door body of the vehicle body. An impact beam disposed so as to extend to the inner panel, an impact beam extension for attaching an end of the impact beam to the inner panel, and the impact beam extension and a connecting portion are integrally formed and A door check bracket that is attached to the door panel and that slidably holds the door check when the door body rotates, and a joint provided on the door check bracket for joining to the door panel. It is characterized by.

  When the door body is rotated, the door check slides to give the operator a moderation appropriate for the rotation of the door body. The sliding force of the door check acts on the joint portion for joining the door check bracket to the door panel, and the door check bracket is integrally formed through the impact beam extension and the connecting portion. Thereby, since the impact beam extension and the impact beam suppress the peeling load that acts on the joint when the door check slides, the peeling of the joint is suppressed, and the durability of the door check bracket is improved.

  According to a second aspect of the present invention, in the first aspect of the present invention, the connecting portion also serves as the joining portion.

  Thereby, compared with the structure which provided the connection part and the junction part separately, a structure becomes simple. Further, since the impact beam extension directly acts on the joint portion and the separation load acting on the joint portion can be suppressed, the separation of the joint portion can be more effectively suppressed.

  According to a third aspect of the present invention, in the second aspect of the present invention, the invention has an inclined portion that is provided on the impact beam extension and extends obliquely with respect to a bonding surface at the bonding portion. To do.

  Therefore, since the peeling load acting on the joint portion is suppressed by the inclined portion, the peeling of the joint portion can be more effectively suppressed as compared with a configuration in which such an inclined portion is not provided.

  Since this invention set it as the said structure, it becomes possible to improve durability of a door check bracket by suppressing peeling of the junction part of the door check bracket resulting from sliding of a door check.

  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 the support end side of the door 104 that is rotatably supported with respect to the vehicle body around one end. FIG. 2 shows a state in which the door 104 is opened by being rotated in this way. In the drawings, the front side 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.

  In addition, the impact beam 116 and the joint 122, that is, the attachment portion of the door weather 134 are connected by the load transmitting portion 128. Therefore, the load from the impact beam 116 can be directly transmitted to the door weather 134 described later.

  As shown in detail in FIG. 4 or FIG. 5, a reinforcing bead 130 is formed from the impact beam fixing portion 126 of the impact beam extension 118 to the load transmitting portion 128. The reinforcing bead 130 is formed at a substantially central position in the vertical direction, and has a shape surrounding the outer periphery of the impact beam 116 in the impact beam fixing portion 126 (substantially semi-cylindrical in this embodiment), and in the vehicle width direction in the load transmitting portion 128. The impact beam extension 118 has a so-called hat-shaped cross section at a portion where the reinforcing bead 130 is formed. The reinforcing bead 130 reinforces the impact beam extension 118, particularly the load transmitting unit 128.

  Similarly, reinforcing flanges 132 are formed from the upper edge and the lower edge of the impact beam extension at a portion of the impact beam extension 118 that extends from the impact beam fixing portion 126 to the load transmitting portion 128. In the portion where the reinforcing flange 132 is formed, the impact beam extension 118 has a flat “U” -shaped cross section. The reinforcing flange 132 also reinforces the impact beam extension 118, particularly the load transmitting portion 128, similarly to the reinforcing bead 130.

  The impact beam extension 118 includes at least an impact beam fixing portion 126 to a load transmission portion 128 that are continuously integrated, including the reinforcing bead 130 and the reinforcing flange 132 described above.

  As shown in FIG. 1, the joint portion 122 of the impact beam extension 118 is joined to the door inner 110 on the opposite side of the door weather attachment portion 136 of the door weather 134 described later and the door inner 110. Therefore, the joint 122 of the impact beam extension 118 also acts as an attachment portion for the door weather 134.

  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.

  The engagement bracket 142 is formed in a flat and 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 142B is open. Further, the surface of the engagement bracket 142 that is located on the inner side in the vehicle width direction when viewed from above is an inclined surface 144 that is acutely inclined with respect to the front-side extension line L2 of the impact beam 116.

  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, when the inclined surface 144 further moves inward in the vehicle width direction in contact with the opposing surface 150. The force in the direction of the arrow F1 (see FIG. 6) acts on the inclined surface 144 from the facing surface 150.

  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 provided with a door check mounting portion 119 to which a door check bracket 178 is joined at a position on the inner side in the vehicle width direction. The door check mounting portion 119 is also formed with an insertion hole 119H through which the door check 174 is inserted.

  Furthermore, the door check bracket 178 is provided with a joint portion 154 that is joined to the door inner 110 on the inner side in the vehicle width direction than the insertion hole 119H. And the door check attachment part 119 to which the door check 174 is slidably attached is set between the joining parts 122 and 154.

  As can be seen from FIGS. 1 and 2 (as also shown in detail in FIGS. 4 and 5), in the present invention, the door check bracket 178 is integrally formed so as to be connected to the impact beam extension 118 via the joint 122. As a whole, one bracket unit 156 is formed. That is, the joint portion 122 functions as a “connecting portion” in the present invention, and the door check bracket 178 and the impact beam extension 118 are integrally formed through the connecting portion. And the load transmission part 128 is extended in the diagonal direction from this junction part 122 (connection part), and the "inclination part" in this invention is comprised.

  Next, the operation of this embodiment will be described.

  The door 104 according to the present embodiment rotates about the rotation center axis 114A of the door hinge 114, and moves between the closed state shown in FIG. 1 and the open state shown in FIG. Here, at the time of rotation, the door check 174 slides on the sliding portion 180, so that a predetermined resistance at a specific position in the middle of rotation is generated, and the feeling of moderation is improved.

  When the door check 174 slides on the sliding portion 180, a load acts on the door check bracket 178. Here, in this embodiment, the door check bracket 178 is integrally formed so as to be continuous with the impact beam extension 118 via the joint portion 122, and the bracket unit 156 is configured as a whole. Therefore, the impact beam extension 118 suppresses the peeling of the joint 122 from the door inner 110. In particular, in the impact beam extension 118, the impact beam 116 is fixed to the impact beam fixing portion 126 on the outer side in the vehicle width direction. Therefore, since the impact beam 116 effectively suppresses the load that acts to peel the joint 122 from the door inner 110, the durability of the door check bracket 178 is improved.

  Further, as shown in FIG. 6, when a load is applied to the door 104 from the side (this case is appropriately referred to as “side collision”), this load first acts on the impact beam 116. Further, the load is a path from the impact beam 116 to the body pillar 106 through the load transmission unit 128, the path from the load transmission unit 128 to the body pillar 106 through the opening 110H and the support member 176, and the door. It is distributed to three paths, the path from the check mounting portion 119 to the body pillar 106, and transmitted to the body pillar 106. In this way, by setting a plurality of load transmission paths, the load from the impact beam 116 at the time of a side collision can be efficiently transmitted to the body pillar 106.

  In particular, in this embodiment, the impact beam extension 118 (particularly the load transmitting portion 128) is reinforced by the reinforcing beads 130 and the reinforcing flanges 132, and the bending strength and rigidity are improved. For this reason, at the time of load transmission from the impact beam 116 to the joint portion 122, inadvertent deformation of the impact beam extension 118 is suppressed and reliable load transmission is possible.

  Further, since the reinforcing flange 132 is continuous from the bracket unit 156 and covers the impact beam fixing portion 126 and the door check mounting portion 119, these portions can be waterproofed (prevention of water) and rust prevention performance can be improved. Can do.

  In the case of a side collision, as can be seen from FIG. 6, the engaging bracket 142 moves inward in the vehicle width direction, and the inclined surface 144 is pressed against the opposing surface 150. Receives force in F1 direction. The door check bracket 178 is moved toward the body pillar 106 by the vehicle forward component of the force F1. That is, the load at the time of a side collision can also be efficiently transmitted to the body pillar 106 by this.

  Further, in the present embodiment, the joint 122 and the door check 174 of the bracket unit 156 are formed in a portion where the door weather 134 is attached, that is, a portion where a structural gap with the body pillar 106 is narrow in the vehicle front-rear direction. Has been placed. Therefore, when an impact is applied from the front of the vehicle, the load from the body pillar 106 is dispersed early into the path from the impact beam extension 118 to the impact beam 116 and the path from the door check 174 to the door inner 110, and the door It can be transmitted to the main body 112.

  Furthermore, in the present embodiment, the impact beam 116 and the joint 122 (that is, the attachment portion of the door weather 134) are connected via the load transmitting portion 128 of the impact beam extension 118, and therefore the door outer when the door 104 is closed. The load from 108 is directly transmitted to the door weather 134, and the closing property of the door 104 is improved. In addition, in this embodiment, since the impact beam 116 and the door check mounting portion 119 of the impact beam extension 118 are also connected, the load when the door 104 is opened and closed can be directly transmitted to the door check 174, and at the time of opening and closing The moderation feeling is improved.

  In the bracket unit 156 according to the present invention, for example, as shown in FIG. 7, a reinforcing flange 133 in which the reinforcing flange 132 is further enlarged may be formed. Here, in the reinforcing flange 133 having the shape shown in FIG. 7A, the protrusion 133T has a concave portion 133B that curves toward the bracket unit 156 at the approximate center in the vehicle width direction. Interference with other members is prevented. When there is no concern about such interference, as shown in FIG. 7B, the reinforcing end 133T may be formed in a straight line without forming the recess 133B, and the reinforcing effect may be further enhanced. .

  FIG. 8 shows a vehicle body side structure 222 according to the second embodiment of the present invention in a state of a front collision. In the bracket unit 224 of the second embodiment, the impact beam fixing portion 126 to which the impact beam 116 is fixed is extended to the door outer 108 and further extended to the front side of the vehicle. Other than this, the configuration is the same as that of the first embodiment, so the same components, members, and the like are denoted by the same reference numerals and detailed description thereof is omitted.

  Therefore, in the vehicle body side surface structure 222 of the second embodiment, the load at the time of a side impact directly acts from the door outer 108 to the bracket unit 224 (impact beam extension 118), and thus this load is transmitted to the body pillar 106 and the like. The effect to do becomes high. In addition, the load F5 applied to the impact beam extension 118 from the body pillar 106 through the door weather 134 at the time of the front collision can be transmitted to the impact beam 116 more efficiently.

  In addition, the length L4 of the bracket unit 224 that joins the door outer 108, that is, the portion that receives the load and kinetic energy from the door outer 108 is longer than the length L5 of the portion that receives the load and kinetic energy from the impact beam 116. Therefore, the effect of transmitting the load at the time of a side collision to the body pillar 106 and the like is enhanced.

  FIG. 9 shows a vehicle body side structure 322 according to a third embodiment of the present invention. The bracket unit 324 of the third embodiment has a joint portion 120 and an impact beam fixing portion 126, and has an outer portion 326 located on the outer side in the vehicle width direction, a load transmission portion 128, and a joint portion 122. It is divided into an inner portion 328 located on the inner side in the direction. The outer portion 326 and the inner portion 328 are joined to each other at the vehicle rear side portion (the joining portion 330 of the inner portion 328 also serves as a part of the load transmitting portion 128), and as a whole, the first embodiment. The impact beam extension 332 having substantially the same shape as the impact beam extension 118 is configured. As described above, a portion corresponding to the impact beam extension of the bracket unit may be divided into parts. In addition, in 3rd Embodiment, since it is the structure similar to 1st Embodiment except this, the same code | symbol is attached | subjected about the same component, a member, etc., and detailed description is abbreviate | omitted.

  FIG. 10 shows a vehicle body side structure 422 according to a fourth embodiment of the present invention. In the bracket unit 424 of the fourth embodiment, an attachment surface 426 to which the door check 174 is slidably attached is formed from the joint portion 122 to the joint portion 154 so as to be substantially linear in a plan view. Thus, since the bent portion is eliminated by making the mounting surface 426 straight, bending is suppressed even if a load acts on the mounting surface 426. In addition, since it is the structure similar to 1st Embodiment other than this in 4th Embodiment, the same code | symbol is attached | subjected about the same component, a member, etc., and detailed description is abbreviate | omitted.

  FIG. 11 shows a vehicle body side structure 522 according to a fifth embodiment of the present invention. In the vehicle body side structure 522 of the fifth embodiment, a concave portion 110D that is partially bent toward the vehicle rear side is formed on the front wall portion 110B of the door inner 110, and a bent portion is formed at a portion corresponding to the concave portion 110D of the bracket unit 524. 524B is formed to form a gap D2 with the body pillar 106. An engagement bracket 526 is disposed in the gap D2. The engagement bracket 526 is attached to the joint portion 122 of the bracket unit 524 by the bolt 138 and the nut 140 as in the first embodiment, and the inclined surface 528 of the engagement bracket 526 is wider than the support member 176 in the vehicle width. Opposite direction. In the fifth embodiment, as in the third embodiment, the impact beam extension 530 is divided into an outer portion 532 and an inner portion 534. Since the fifth 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.

  Therefore, in the vehicle body side structure 522 of the fifth embodiment, the load at the time of a side collision is transmitted to the support member 176 via the engagement bracket 526 and further transmitted to the body pillar 106. That is, more efficient load transmission to the body pillar 106 at the time of a side collision becomes possible.

  In the above description, the engagement bracket 526 is attached to the joint portion 122 of the bracket unit 524 with the bolt 138 and the nut 140. However, the attachment method is not limited to this. For example, a rivet 536 may be used for attachment as in a modification of the fifth embodiment shown in FIG.

  FIGS. 13A and 13B show a bracket unit 624 according to a sixth embodiment of the present invention. In the fifth embodiment, the shape of the bracket unit is different from that in the first embodiment, but the other components are the same as those in the first embodiment, and therefore the same components, members, etc. are denoted by the same reference numerals. Detailed description will be omitted. In FIG. 13, the impact beam 116 has a substantially trapezoidal cross section unlike the above, and the impact beam extension 630 also has an impact beam fixing portion 632 having a shape corresponding thereto. The structures of the impact beam 116 and the impact beam extension are not particularly limited.

  In the bracket unit 624 of the sixth embodiment, as can be seen from FIG. 13B, the impact beam fixing portion 632 extends to the door outer 108, and an adhesive piece 626 parallel to the door outer 108 is further provided from the tip. It extends up and down. Further, a reinforcing bead 628 is provided between the extended portion of the impact beam fixing portion 126 and the adhesive piece 626 to reinforce the adhesive piece 626. The adhesive piece 626 is bonded to the door outer 108 and the impact beam 116 with an adhesive 634.

  In the sixth embodiment, since such a bracket unit 624 is provided, the load from the door outer 108 at the time of a side collision can be transmitted to the bracket unit 624 (impact beam extension 118) more efficiently.

  FIG. 14 shows a vehicle body side structure 722 according to a seventh embodiment of the present invention. In the seventh embodiment, only the shape of the bracket unit 724 is different from that of the first embodiment. However, since all other parts have the same configuration, only the different configuration will be described.
