Description

  The present invention relates to a vehicle load transmission structure that transmits an impact load during a collision or the like to a vehicle body floor.

  For example, there is known a vehicle load transmission structure that transmits an impact load input from the side of a vehicle body to a vehicle body floor through a seat on which an occupant is seated in a side collision. In this type of load transmission structure, an impact load input to a seat is applied to a floor (for example, a floor tunnel) via a reinforcing body (for example, a console box) installed on the floor adjacent to the inner side in the vehicle width direction of the seat. ) Is transmitted (see, for example, Patent Document 1).

  Furthermore, a load transmission member is provided on a side surface of the seat that faces the reinforcement body, and the load transmission member is set to abut against the reinforcement body when the seat is displaced inward in the vehicle width direction by an impact load input to the seat. However, it has been considered that an impact load is transmitted to the floor via the load transmitting member and the reinforcing body.

JP 2005-67427 A

  However, depending on the state of input of the impact load at the time of a side collision, the impact load may be transmitted obliquely downward from the seat to the load transmission member, and in such a case, the load transmission is performed in the reinforcing body. When the receiving surface with respect to the member is formed flat, the load transmitting member is slid downward along the receiving surface of the reinforcing body while being compressed and deformed after hitting the reinforcing body, and the load transmission is sufficient. There is a problem that it will not be performed.

  In addition, when the load transmission member slides downward, a moment that tilts the upper part of the seat toward the inside of the vehicle is generated. However, if the load is not sufficiently transmitted to the reinforcement, a sufficient reaction force from the reinforcement is obtained. As a result, it becomes difficult to counter the moment, and the seat easily tilts toward the inside of the vehicle. As a result, the effect of suppressing the vehicle body side portion from entering the vehicle inside (vehicle body entry suppressing effect) is reduced. Arise.

  Therefore, the present invention provides a load transmission structure for a vehicle that can sufficiently exert a vehicle body invasion suppressing effect.

The vehicle load transmission structure according to the present invention employs the following means in order to solve the above problems.
The invention according to claim 1 is provided adjacent to the inner side in the vehicle width direction of a seat (for example, a vehicle seat 1 in an embodiment to be described later) on which an occupant sits, and is input to the seat from the side of the vehicle body. In a vehicle load transmission structure including a reinforcing body (for example, a console box 30 in an embodiment to be described later) that transmits a vehicle body floor (for example, a floor tunnel 12 in an embodiment to be described later), the seat includes the reinforcing body. A load transmission member (for example, a load transmission block 26 in an embodiment to be described later) is provided on a side surface (for example, a side frame 13d in an embodiment to be described later), and the reinforcing body is opposed to the load transmission member. Under the load transmitting member in a state where the load transmitting member is in contact with a side wall portion (for example, a side wall plate 31 in an embodiment described later). Example, load receiving portion for supporting the lower surface 26a) in Examples described later (for example, a load transfer structure of the vehicle, characterized in that the load receiving member 60) is provided in the embodiment to be described later.

  The invention according to claim 2 is the invention according to claim 1, wherein the reinforcing body is a reinforcing member that connects the left and right side wall portions (for example, a front plate 33, a rear plate 34, and a box in an embodiment described later). Cross members 36 and 37), and the reinforcing member is provided above the load receiving portion.

According to the first aspect of the present invention, since the load transmission member is supported by the load receiving portion so that the load transmission member is prevented from further downward movement, the load transmission member is attached to the side wall portion of the reinforcing body. It can prevent sliding down along. Thereby, the impact load input to the seat can be transmitted from the load transmitting member to the reinforcing body with sufficient reliability, and as a result, the vehicle body can be reliably prevented from entering the vehicle interior.
According to the invention which concerns on Claim 2, a load transmission member can be received in the part reinforced by the reinforcement member in the reinforcement body, and load transmission can be performed more reliably.

  The load receiving member 60 is made of metal and has rigidity. As shown in FIG. 1, the load receiving member 60 has a substantially square shape as viewed from the front, the lower part is connected to the vehicle body floor 9 and the floor tunnel 12, and the upper part is the console box 30. It is connected to the lower end of the side wall plate 31. The length of the load receiving member 60 in the longitudinal direction of the vehicle body is set to be substantially the same as the length in the longitudinal direction of the console box 30, and is installed along the entire length of the console box 30. Further, the upper surface 61 of the load receiving member 60 is formed as a flat surface. As shown in FIG. 4, the upper surface 61 of the load receiving member 60 is lower than the lower surface 26 a of the load transmission block 26 provided on the seat 1. Is positioned so as to extend substantially horizontally in the vehicle front-rear direction at a slightly lower position, and is connected and fixed to the vehicle body floor 9, the side surface of the floor tunnel 12, and the side wall plate 31 of the console box 30. Note that any appropriate means such as welding or bolt fastening can be employed as the fixing means.

  The load receiving member 60 only needs to be fixed to at least the console box 30. Therefore, the lower portion of the load receiving member 60 may not extend to the vehicle body floor 9, or may not extend to the floor tunnel 12. However, it may not be connected to the vehicle body floor 9 or may not be connected to the floor tunnel 12.

Further, the load transmission block 26 is disposed so as to contact the side wall plate 31 of the console box 30 positioned higher than the upper surface 61 of the load receiving member 60 when moved inward in the vehicle width direction. The installation position of the console box 30 and the length in the longitudinal direction of the vehicle are set so that the end face 26b of the load transmission block 26 comes into contact with the side wall plate 31 of the console box 30 even when the position is adjusted in the longitudinal direction of the vehicle body. . In FIG. 3, a two-dot chain line indicates a range in which the contact portion of the end face 26b of the load transmission block 26 with the side wall plate 31 moves in accordance with the front / rear position adjustment of the seat cushion 2 (hereinafter referred to as a load receiving region). S is shown.
As described above, the load receiving region S is positioned higher than the upper surface 61 of the load receiving member 60 and lower than the uppermost point of the console box 30 and extends over the entire length of the console box 30 in the longitudinal direction of the vehicle body. And most of the front plate 33, the rear plate 34, the reinforcing frame 35, and the box cross members 36 and 37 in the console box 30 are arranged in the load receiving region S.

  In the vehicle load transmission structure configured as described above, when an impact load is input from the side of the vehicle and the side wall of the vehicle body such as the center pillar 11 is deformed in the direction of the seat back 3, the load from the side wall is a vertical load. It is transmitted to the side frame 13c via at least one of the transmission blocks 21 and 25.

  When an impact load is input to the lower load transmission block 25, the lower load transmission block 26 comes into contact with the console box 30 as the entire seat 1 moves inward in the vehicle width direction. A load is transmitted from the lower cross member below the frame 13 to the floor tunnel 12 via the load transmission block 26 and the console box 30.

  When an impact load is input to the upper load transmission block 21, the load is transmitted to the side frame 13 c and simultaneously input to the plate material 14 via the cross member 16.

  The impact load input to the cross member 16 along the axial direction is input from the cross member 16 to the upper end portion of the plate material 14, and is applied to a plurality of regions partitioned by the ridge line portions a of the uneven portions 15 of the plate material 14. Causes stress in the shear direction. Thereby, the input impact load can be received in almost the entire area of the plate material 14.

  Thus, when the collision load is distributed and transmitted to almost the entire area of the side frame 13c and the plate member 14, the load transmission block 26 comes into contact with the console box 30 as the entire seat 1 moves inward in the vehicle width direction. The load is transmitted to the floor tunnel 12 through the console box 30.

  By the way, when the load transmission block 26 approaches the console box 30 with the movement of the entire seat 1 in the vehicle width direction, the load transmission block 26 is provided on the side of the console box 30 where the seat 1 approaches. Passing over the upper surface 61 of the load receiving member 60 and approaching the console box 30, the end face 26 b of the load transmitting block 26 is finally brought into contact with the side wall plate 31 of the console box 30. When an impact load is transmitted from the load transmission block 26 to the console box 30 with the end face 26b of the load transmission block 26 in contact with the side wall plate 31 of the console box 30, the load transmission block 26 is pushed downward. When the force acts, as shown in FIG. 5, the lower surface 26a of the load transmission block 26 abuts on the upper surface 61 of the load receiving member 60, and the load transmission block 26 is supported from below by the load receiving member 60. The load transmission block 26 is prevented from further downward movement. As a result, the load transmission block 26 can be prevented from sliding downward along the side wall plate 31 of the console box 30, and the impact load input to the seat 1 can be transferred from the load transmission block 26 to the floor via the console box 30. It becomes possible to transmit to the tunnel 12 with sufficient reliability. As a result, since the seat 1 receives a large reaction force from the console box 30, it is possible to resist a moment that tilts the upper side of the seat 1 inward in the vehicle width direction, and the vehicle interior side such as the center pillar 11 The effect of suppressing entry into the vehicle, that is, the effect of suppressing vehicle entry is great.

  Further, when a load is transmitted from the load transmission block 26 to the console box 30 when an impact load is input, the end surface 26b of the load transmission block 26 first comes into contact with the side wall plate 31 of the console box 30, and at this time, The impact load is transmitted to the front plate 33 and the rear plate 34 through the reinforcing frame 35 having high rigidity in the bending direction, and is also transmitted to the lower plate 32 and the box cross members 36 and 37. The load transmitted to the front plate 33 and the rear plate 34 is transmitted to the lower plate 32 and the box cross members 36 and 37, and is transmitted directly from the side wall plate 31 to the lower plate 32 and the box cross members 36 and 37. It is transmitted to the joint with the floor tunnel 12 together with the load.

  Here, since the side wall plate 31 is reinforced by a reinforcing frame 35 that extends in the longitudinal direction of the vehicle body and is coupled to the front plate 33 and the rear plate 34, the bending rigidity is maintained high throughout the longitudinal direction of the vehicle body. Yes. Further, as described above, most of the front plate 33, the rear plate 34, the reinforcing frame 35, and the box cross members 36 and 37 in the console box 30 are disposed in the load receiving area S, so Even if the front / rear position is changed by the adjustment, the load transmission block 26 can be received by the portion reinforced in the console box 30 at all times. As a result, load transmission from the load transmission block 26 to the console box 30 can be performed more reliably and efficiently.

In addition, the console box 30 is provided with a front plate 33 having a closed cross-section structure and a reinforcing frame 35 that reinforces the impact load input from the load transmission block 26 of the seat 1 so as to increase the bending rigidity of the side wall plate 31. Since it can be transmitted to the rear plate 34, the input load can be efficiently transmitted to the floor tunnel 12 without causing an increase in the thickness of the members around the storage portion 30a.
Therefore, it is possible to quickly transmit the impact load to the floor tunnel 12 on the center side in the vehicle width direction without causing an increase in the weight of the vehicle or a decrease in the space of the storage portion 30a.
