Description

  The present invention relates to a triangular window reinforcing structure in a front pillar of an automobile having a triangular window opened.

Conventionally, in a vehicle of a type in which a triangular window is disposed in front of the front door opening, various techniques for suppressing local deformation of the lower portion of the triangular window at the time of a frontal collision are used to compensate for the insufficient strength due to the opening of the triangular window. Proposed. Normally, a reinforcing member for a hinge portion of a front door, a reinforcing member for holding a steering beam and a cowl, and the like are disposed at the lower part of the triangular window, which is an important part as a reinforcing structure. As an example of such a reinforcing structure, there is a technique in which a front pillar is composed of a plurality of inner and outer panels, and the collision energy at the time of a frontal collision is distributed to pillar inners and pillar outers (see, for example, Patent Document 1 below).
JP-A-8-80868 (see FIG. 5)

  With reference to FIG. 4, the front vehicle body structure disclosed in Patent Document 1 will be described. In this vehicle body structure, the front pillar 104 includes a front pillar inner upper 114, a front pillar lower 116, a cowl coupling bracket 117, a front pillar stiffener 115, and a front pillar outer upper 120, and is integrated with the front pillar inner upper 114. The front side windshield 105 is mounted on the triangular windshield support frame 112 formed in the above. The front pillar inner upper 114 is reinforced by the windshield support frame 112.

  With such a configuration, the support frame 112 of the fixed front side windshield 105 disposed between the front pillar 104 and the side door windshield (not shown: front door windshield) is integrally formed with the front pillar 104. The support pillar 112 can reinforce the front pillar 104 to increase its rigidity. As a result, the weight of the vehicle body can be reduced without increasing the thickness of the front pillar 104.

  However, although such a highly rigid reinforcing structure enables collision energy to be distributed to the pillar inner and pillar outer in the front pillar, such a conventional structure has a large rigidity in the front-rear direction due to the presence of the cowl coupling bracket 117 and the like. However, the lack of rigidity in the vertical direction cannot be denied. For this reason, the deformation at the time of frontal collision cannot be suppressed and the door opening is deformed, which may affect the door opening performance after the collision.

  Therefore, the present invention solves the problems of the conventional triangular window reinforcement structure and can dramatically improve rigidity by adding and renovating simple parts. Vibration due to mounting rigidity around the door hinge and steering beam mounting rigidity It aims at providing the triangular window reinforcement structure which enabled improvement etc.

  Therefore, the present invention is characterized in that in a triangular window reinforcing structure in a front pillar of an automobile having a triangular window opened, a vertical reinforcing structure is combined with a phosphorus hose beam steering to which a steering beam is attached. Further, the present invention is characterized in that the phosphorus hose beam steering and vertical reinforcing structure are joined and disposed between a front pillar inner and a phosphorus hose front pillar. Further, the present invention is characterized in that an upper end portion of the vertical reinforcing structure is joined at a front end portion of the triangular window. Further, the present invention is characterized in that each of the phosphorus hose beam steering and the longitudinal reinforcing structure has a joint portion to both the front pillar inner and the phosphorus hose front pillar. Further, the present invention is characterized in that the phosphorus hose beam steering is joined by connecting a front pillar inner upper and a front pillar inner lower. Further, the present invention is characterized in that the phosphorus hose beam steering is joined by connecting a phosphorus hose front pillar upper and a phosphorus hose front pillar lower, and these are used as means for solving the problems. It is.

  According to the present invention, in a triangular window reinforcing structure in a front pillar of an automobile having an opened triangular window, a longitudinal reinforcing structure is combined with a phosphorus hose beam steering to which a steering beam is attached, thereby providing a conventional horizontal hose by a phosphorus hose beam steering. While securing rigidity, it is expected that the vertical rigidity will be improved, local deformation at the bottom of the triangular window during frontal collision is effectively suppressed, and displacement between the inner and outer pillar panels is also suppressed, improving the mounting rigidity around the door hinge Further, vibration can be improved by improving the steering beam mounting rigidity.

  In addition, when the phosphorus hose beam steering and vertical reinforcement structure are joined and arranged between the front pillar inner and the phosphorus hose front pillar, the lateral and vertical reinforcements of these members complement each other. As a result, the reinforcing function of the phosphorus hose front pillar can be ensured. Further, when the upper end portion of the vertical reinforcing structure is joined at the front end portion of the triangular window, it effectively reinforces the impact load from the front to the triangular window opening which tends to be particularly low in strength. It becomes possible.

  Furthermore, when each of the phosphorus hose beam steering and the vertical reinforcing structure has a joint to both the front pillar inner and the phosphorus hose front pillar, the reinforcing structures are respectively the front pillar inner and the phosphorus hose front. All of the pillars are securely connected to each other and become stronger as a reinforcing structure. Further, when the phosphorus hose beam steering is joined by connecting the front pillar inner upper and the front pillar inner lower, the split front pillar inner is reliably joined and reinforced, and the front pillar front portion is Stiffness is improved.

  Further, when the phosphorus hose beam steering is joined by connecting the phosphorus hose front pillar upper and the phosphorus hose front pillar lower, the divided phosphorus hose pillar is reliably reinforced, and the front pillar front portion is reinforced. The rigidity will be improved.

It is the side view which looked at the front pillar inner of the state which attached A from the outside.

  As shown in FIG. 1, the basic structure of the triangular window reinforcing structure of the present invention is a phosphorus hose beam steering 10 to which a steering beam is attached in a triangular window reinforcing structure in a front pillar 1 of an automobile having a triangular window 12 opened. A vertical reinforcing structure (patch) 11 is combined.

  FIG. 1 is an exploded perspective view of the front pillar 1 in which a triangular window 12 is formed, and shows the front pillar 1 on the right side of the vehicle body. It is disposed at the front of a right front door opening (shown by reference numeral 13) (not shown). The front pillar 1 is formed by joining a front pillar inner 2, a phosphorus hose front pillar 3, and a panel side outer 4 in which a triangular window 12 is formed in order from the inside of the vehicle body. The front pillar inner 2 includes a front pillar inner upper 5 and a front pillar inner lower 6 connected to a lower portion thereof. The phosphorus hose front pillar 3 disposed outside them is composed of a phosphorus hose front pillar upper 8 and a phosphorus hose front pillar lower 9 connected to the lower part thereof. Further, the panel side outer 4 arranged at the outermost part is integrally formed so as to surround the front door opening.

  In order to join the three panels 2, 3 and 4 to form the front pillar 1, first, the phosphorus hose front pillar 3 and the panel side outer 4 are joined, and then the front pillar inner 2 is joined. . A bracket front pillar 7 is connected and reinforced over the front pillar inner upper 5 and the front pillar inner lower 6 connected to the lower portion thereof. In the present invention, in addition to the phosphorus hose beam steering 10 which mainly has a high reinforcing effect in the front-rear direction between the front pillar inner 2 and the phosphorus hose front pillar 3, a vertical reinforcing structure ( Patch) 11 was disposed.

  FIG. 2A shows an example of the structure of the patch 11 and the phosphorus hose beam steering 10. The phosphorus hose beam steering 10 has a longitudinal direction for joining the front pillar inner 2 and the phosphorus hose front pillar 3. It has a crank-shaped cross section when viewed from above, and the reinforcing effect in the front-rear direction is high, but the reinforcing effect in the vertical direction is low. Therefore, in the present invention, the hat-like patch 11 is combined with the phosphorus hose beam steering 10 as viewed from above and below. The numbers given to S (joining by spot welding or the like) shown on each surface of the patch 11 and the phosphorus hose beam steering 10 indicate the code numbers of the mating members to be joined. For example, S9 indicates a joint portion with the phosphorus hose front pillar lower 9, and S6 indicates a joint portion with the front pillar inner lower 6.

  As shown by the arrows in FIG. 2A, the three S10s in the patch 11 are joined to the three S11s in the phosphorus hose beam steering 10. As a result, as shown in FIG. 2B, the two are joined and combined by the joints S10 and 11 at three locations. The patch 11 and the phosphorus hose beam steering 10 combined in this way are joined and disposed between the front pillar inner 2 and the phosphorus hose front pillar 3.

As described above, the patch 11 and the phosphorus hose beam steering 10 are joined by the joints S10, 11 at three locations. The upper end of the patch 11 is joined to the phosphorus hose front pillar lower 9 by S9 at the front end of the triangular window 12. The central flat surface portion and the convex surface of the lower end portion of the patch 11 are also joined to the phosphorus hose front pillar lower 9 by S9.

  Referring to FIG. 2 (A), the phosphorus hose beam steering 10 is configured such that the upper end portion, the intermediate portion, and the lower end portion of the front side (the phosphorus hose front pillar 3 side) are flat at the phosphorus hose front pillar lower 9 by S9. In addition, the upper flat portion on the other side (front pillar inner 3 side) is joined to the front pillar inner upper 5 by S5, and the lower flat portion is joined to the front pillar inner lower 6 by S6. Further, the rear end portions of the upper and lower planar portions are joined to the phosphorus hose front pillar lower 9 by S9. Further, the rear end portion of the lower flat portion on the other side is joined to the front pillar inner lower 6 by S6. In addition, a bent plane extending backward from the slope between the lower flat portion on the near side and the lower flat portion on the other side is joined to the phosphorus hose front pillar lower 9 by S9.

  Thus, the vertical rigidity is improved by the patch 11 while securing the conventional lateral rigidity by the phosphorus hose beam steering 10, and even if a collision load as indicated by the arrow F is applied from the front during a frontal collision, The deformation is effectively suppressed and is effectively dispersed as indicated by arrows F1 and F2. Therefore, in particular, the breakage of the A part and the B part can be suppressed, and the displacement between the inner and outer pillar panels is also suppressed, so that the mounting rigidity around the door hinge can be improved and the vibration can be improved by improving the steering beam mounting rigidity. Further, since the phosphorus hose beam steering 10 and the patch 11 are joined and arranged between the front pillar inner 2 and the phosphorus hose front pillar 3, the lateral and vertical reinforcement of these members can be mutually performed. Complementing each other, the reinforcing function by the phosphorus hose front pillar 3 can be ensured.

  Further, when the upper end portion of the vertical reinforcing structure 11 is joined at the front end portion of the triangular window 12, it is particularly effective against an impact load from the front to the triangular window opening which tends to be low in strength. Furthermore, each of the phosphorus hose beam steering 10 and the longitudinal reinforcing structure 11 has a joint portion to both the front pillar inner 2 and the phosphorus hose front pillar 3, and the respective reinforcing structures are Both the front pillar inner 2 and the phosphorus hose front pillar 3 are securely connected to each other, and the reinforcing structure becomes stronger. Further, the phosphorus hose beam steering 10 is joined by connecting the front pillar inner upper 5 and the front pillar inner lower 6, so that the split front pillar inner 2 is reliably joined and reinforced so that the front pillar 1 The rigidity of the front part is improved. In addition, the phosphorus hose beam steering 10 is joined by connecting the phosphorus hose front pillar upper 8 and the phosphorus hose front pillar lower 9, and the divided phosphorus hose front pillar 3 is reliably reinforced, so that the front pillar 1 The rigidity of the front part is improved.
