Description

  The present invention relates to a vehicle body structure that has high rigidity in a driver seat and a rear portion of the driver seat and secures a passenger space in the driver seat at the time of a collision.

  In vehicles such as buses, a vehicle body structure in which a strength member is provided in a side wall of a driver's seat part is known in order to secure an occupant space in the driver's seat part at the time of a frontal collision. Such a strength member is, for example, between the front pillar and the second pillar behind the driver's seat, and fixes the driver's seat directly below the driver's seat window opened to the side of the driver's seat. There is an example provided along the front-rear direction substantially parallel to the driver seat floor member.

Japanese Laid-Open Patent Publication No. 2002-68011 discloses a bus frame structure in which a sub-frame is provided on the driver seat side of the main frame and the frame of the other vehicle is prevented from entering the driver seat portion when it collides with the rear part of the other vehicle.

The spring holding member 16 includes an oblique connecting member 18 at the front and rear, and is attached to the side surface of the lateral connecting member 60 together with the oblique connecting member 18. The oblique connecting member 18 is attached to both the front and rear surfaces of the spring holding member 16 at substantially the same angle. FIG. 3 shows a state in which the chassis portion 12 and the body portion 14 are assembled together.

  Next, functions and effects of the vehicle body structure 10 will be described.

  It is assumed that a vehicle equipped with the vehicle body structure 10 collides with something and a pressing force is applied in front of the vehicle body structure 10. Then, the pressing force pushes the front frame 13 downward, pushes the front wind lower frame 21 backward, and presses the left and right front pillars 20.

  The pressing force input from the front frame 13 to the chassis portion 12 passes through the front frame 13 and presses the suspension suspension member 15 backward. Since the spring holding member 16 is attached to the suspension suspension member 15, the spring holding member 16 tries to push the lateral coupling member 60 downward.

  The horizontal connecting member 60 has high rigidity because the members are configured in two upper and lower stages, and since the horizontal connecting member 60 is connected to the side body skeleton member 23 via the vertical connecting member 63, The pressing force is transmitted to the side body skeleton member 23. In addition, since the front and rear of the horizontal connecting member 60 are attached to the first diagonal reinforcing member 55 and the second diagonal reinforcing member 57, force is transmitted to the first diagonal reinforcing member 55 and the second diagonal reinforcing member 57.

  The first diagonal reinforcing member 55 receives a force pulled backward by the spring holding member 16, but the second lateral connecting member 61 is connected to the first intermediate pillar 24, and the diagonal reinforcing member 62 is connected to the first intermediate pillar 24. Since it is attached, the backward movement is suppressed by these members. Further, the second diagonal reinforcing member 57 receives a force pushed downward by the lateral connecting member 60, but the force is transmitted to the side body skeleton member 23 through the diagonal reinforcing member 65, and the backward movement is suppressed.

  In addition, since the diagonal connecting members 18 are attached to the front and rear of the left and right ends of the spring holding member 16, when the spring holding member 16 is pushed backward, the force can be reliably transmitted to the horizontal connecting member 60 and the front and rear direction. The horizontal connecting member 60 is pushed backward as it is. Therefore, the horizontal connecting member 60, the first diagonal reinforcing member 55, the second diagonal reinforcing member 57, and the like do not generate a rotational force around the coupling portion between the spring holding member 16 and the horizontal connecting member 60, and the horizontal connecting member. The deformation which moves 60, the 1st diagonal reinforcement member 55, the 2nd diagonal reinforcement member 57, etc. in the width direction is not produced.

  On the other hand, on the driver's seat side, the front pillar 20 is directly pressed by the collision object through the front wind lower frame 21, and the side wall of the driver's seat, that is, the front surface of the reinforcing panel 40 is pressed rearward. Since the reinforcing panel 40 has a structure in which the third strength members 35 and the like are diagonally connected to the inside of the reinforcing panel 40 as described above, the reinforcing panel 40 has high rigidity and is not easily buckled and deformed.

  The force pressing the reinforcing panel 40 is transmitted to the connecting member 51 and the inclined member 53 via the second pillar 22. The force that has passed through the inclined member 53 from the connecting member 51 via the second pillar 22 is directly input to the side body skeleton member 23 from below. This prevents the driver's seat portion from being retracted and lifted upward.

  On the other hand, the force passing through the connecting member 51 from the second pillar 22 presses the first intermediate pillar 24 backward. The pressing force is input to the first diagonal reinforcing member 55 via the second lateral connecting member 61 and presses the side body skeleton member 23 rearward through the first diagonal reinforcing member 55.

  As described above, the force from the reinforcing panel 40 is transmitted to the side body skeleton member 23 via the connecting member 51, the second lateral connecting member 61, and the first intermediate pillar 24, so that the pressing force applied to the driver's seat portion. Is received by the side body skeleton member 23. Further, the pressing force is transmitted to the side body skeleton member 23 in this way, and the reinforcing members 34 and 52 are provided on the front surface and the rear surface of the second pillar 22, so that the right front pillar 20 receives them. The backward pressing force can be reliably transmitted from the third strength member 35 to the side body skeleton member 23 via the connecting member 51, the inclined member 53, and the like, and the reinforcing panel 40 and the side body skeleton member 23 are vertically moved. Even if they are provided apart from each other, the stress does not concentrate on the second pillar 22 due to the offset.

  As described above, the vehicle including the vehicle body structure 10 transmits the pressing force applied to the chassis portion 12 to the side body skeleton member 23 via the spring holding member 16 at the time of a collision. The rear part of the chassis part 12 is not damaged and the rear part of the chassis part 12, that is, the suspension suspension member 15 of the front wheel is moved rearward, without causing a backward movement or deformation due to the force transmitted only to the members arranged in Can be suppressed.

  In addition, the vehicle body structure 10 can reliably prevent the chassis portion 12 from retreating without particularly changing the structural members behind the chassis portion 12, for example, the structural members constituting the trunk room. Therefore, the vehicle body structure 10 can realize high rigidity at a low cost with few changes to the conventional chassis.

  Further, the vehicle including the vehicle body structure 10 does not easily deform the driver's seat part due to the pressing force applied to the side of the driver's seat part. The member 23 is reliably transmitted, and the rear portion of the driver's seat portion is not damaged greatly. Thereby, the passenger | crew space of a driver's seat part can be ensured also at the time of a vehicle collision.

  Further, according to the present invention, in a large sightseeing bus provided with a passenger seat portion at a high position, an impact force is applied between the reinforcing member of the driver seat portion and the skeleton member of the passenger seat portion without changing the position of the driver seat or the reinforcing member thereof. Can be connected to each other so that the driver seat can have sufficient strength and high rigidity without changing the design of the high passenger seat with a good view and the low driver seat that is easy to drive, and the design of the vehicle. A highly safe vehicle can be configured.
