[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure of a connecting portion between a front pillar and a front deck in a vehicle.
[0002]
[Prior art]
In a vehicle, a front cowl extending in the vehicle width direction, that is, a front deck and a front pillar each have a box shape in section, and the front deck and the front pillar connected by a reinforcing panel is described in Japanese Utility Model Publication No. 4-3873. However, in this case, since the front deck and the front pillar and the reinforcing panel are connected in the horizontal direction at the same height, the connection structure is not necessarily strong against loads including components in the vertical direction. In particular, like an open car, a heavy windshield with a relatively large inclination to the rear upper part is supported by the front pillar, and the front pillar is cantilevered by the vehicle body at the bottom. Nevertheless, the front pillar cross-sectional area is also restricted in consideration of the driver's field of view. The vehicle, when a relatively large load is applied running from each direction with respect to the front pillar, there is a possibility that shaking occurs in the windshield insufficient rigidity of the front pillar.
[0003]
[Problems to be solved by the invention]
The present invention aims to increase the rigidity of the front pillar by firmly connecting the front pillar and the front deck of the vehicle.
[0004]
[Means for Solving the Problems]
For this reason, in the vehicle body structure according to the present invention, a gusset is hung on the closed cross-section front pillar and the closed cross-section portion of the front deck, which are arranged to cross each other, and the gusset is closed to the front pillar and the front deck. The plurality of bolts that are fixed to the cross-sectional portion at positions shifted in the vehicle longitudinal direction and the vehicle width direction by a plurality of bolts, and the plurality of bolts that fix the gusset and the front pillar are arranged at intervals in the vertical direction. fixation of the gusset between said plurality of bolts for fixing the front deck closed cross section are arranged at intervals in the vehicle width direction Rutotomoni, for fixed center and the front deck closed cross section of the gusset with respect to the front pillar The center is configured to be displaced in the vertical direction.
[0005]
In other words, the closed cross-section front pillar and the closed cross-section portion of the front deck that are crossed with each other are connected by gussets, making it easy to connect the two firmly, and the gusset is closed by the front pillar and front deck. A plurality of bolts for fixing the gusset and the front pillar and a plurality of bolts for fixing the gusset and the front deck closed cross-section portion are fixed to the cross-sectional portion by a plurality of bolts at positions shifted in the vehicle longitudinal direction and the vehicle width direction, respectively. sequence Rutotomoni different from each upper and lower and the vehicle width direction, the fixed center of the gusset against the front pillar and the front deck closed cross section is deviated in the vertical direction, the front pillar and the front deck closed cross section and the gusset and the vehicle, respectively front-rear direction, is connected in a direction inclined from the vehicle width direction and the vertical direction, One, since even different arrangement direction of the bolt, the rigidity of the front pillar easily by gussets for all directions, and can be reliably improved.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention shown in the drawings will be described below.
In a vehicle, a front pillar 1 is formed in a closed cross-section by joining an outer 2 and an inner 3 to each other, and a front deck 4 having a substantially U-shaped cross section that opens upward and extends in the vehicle width direction is illustrated as front pillar 1. The end portion is connected to the connecting portion with the side frame not to be connected, and the substantially U-shaped cross-sectional reinforcing member 5 that opens to the front of the vehicle and extends in the vehicle width direction is joined to the rear side of the vehicle. A closed section 6 extending in the direction is formed.
[0007]
Further, a gusset 10 having a substantially L-shaped cross section is hung on the vehicle rear side wall surface 7 of the front deck closed cross section 6 and the vehicle interior side wall surface 8 of the front pillar 1, and the first contact surface 11 of the gusset 10 is a vehicle. While fixed to the front deck wall surface 7 by two bolts 12 extending in the longitudinal direction of the vehicle at intervals in the width direction, the second contact surface 13 of the gusset 10 is spaced in the vehicle width direction at intervals in the vertical direction. It is fixed to the front pillar wall surface 8 by two extending bolts 14. In this case, the bolts 12 and 14 are arranged at positions shifted in the vehicle front-rear direction and the vehicle width direction, respectively, and the first contact by the bolt 12 is used. The fixed center 13a of the second contact surface 13 by the bolt 14 is located above the fixed center 11a of the surface 11.
[0008]
That is, since the closed cross-section portion 6 of the front deck 4 and the front pillar 1 having a closed cross-section are connected by the gusset 10, the front deck 4 and the front pillar 1 are firmly connected by the gusset 10. In addition, the gusset 10 is configured such that the first contact surface 11 and the second contact surface 13 are respectively connected to the front deck closed cross-section portion 6 and the front pillar 1 by a plurality of bolts 12 and 14 in the vehicle longitudinal direction. It is fixed at a position shifted in the vehicle width direction, and the front pillar wall surface of the second contact surface 13 by the plurality of bolts 14 and the fixed center 11a of the first contact surface 11 by the plurality of bolts 12 with respect to the front deck closed cross-section portion 6 and the plurality of bolts 14. As a result, the front deck closed cross-section portion 6 and the front pillar are shifted from the fixed center 13a with respect to 8 in the vertical direction. 1 is connected by a gusset 10 in a vehicle front-rear direction, a vehicle width direction, and a direction inclined from the vertical direction, so that the rigidity of the front pillar 1 in all directions is easily and reliably increased by the gusset 10, Even when a load is applied to the front pillar 1 when the vehicle is traveling, it is possible to easily suppress the front pillar 1 from being bent and the windshield supported by the front pillar 1 from being shaken.
[0009]
Further, since the rigidity of the front pillar 1 can be easily improved by the arrangement of the front deck closed section 6 and the gusset 10 with respect to the front pillar 1, the gusset 10 can be reduced in size, and the gusset 10 can be reduced. The increase in weight and cost due to the use of can be reduced.
[0010]
【The invention's effect】
In the vehicle body structure according to the present invention, since the front cross-section of the closed cross section and the closed cross-section portion of the front deck are connected by the gusset, it is easy to firmly connect both, and the front pillar and the front deck closed cross-section portion The gusset is connected in the vehicle longitudinal direction, the vehicle width direction, and the direction inclined from the vertical direction , and the bolt arrangement direction is also different , and the rigidity of the front pillar in all directions is easily and reliably made by the gusset. Since it can be improved, there is an advantage that the deflection of the front pillar can be prevented and the windshield supported by the front pillar can be easily prevented from shaking.
