[Problems to be solved by the invention]
However, in the pillar structure of these vehicles, although it is possible to improve the impact mitigation performance against a collision body that has collided with the windshield glass, some pillars and the like, which are frame members supporting the windshield glass, are weakened. As a result, the support rigidity of the windshield glass decreases, which causes noise due to the vibration of the windshield glass.
[0008]
The present invention has been made in consideration of the above-described circumstances, and has as its object to obtain a pillar structure of a vehicle that can improve the impact mitigation performance against a collision object that has collided with the windshield glass and can improve the support rigidity of the windshield glass.
[0009]
[Means for Solving the Problems]
The pillar portion structure of the vehicle according to the first aspect of the present invention includes a pillar frame member that forms a pillar frame,
A windshield glass in which the vehicle width direction end of the main body is bent toward the vehicle rear diagonally outward and is a mounting portion,
And a vehicle width direction outer end of a mounting portion of the windshield glass is fixed to the pillar frame member.
[0010]
Therefore, the end of the windshield glass in the vehicle width direction is bent toward the vehicle rear diagonally outward to form a mounting portion, and the vehicle width direction outer end of the mounting portion is fixed to the pillar frame member. A space is formed between the pillar skeleton member, which bears strength and rigidity, and the windshield glass. As a result, when the collision object collides with the windshield glass, the deformation stroke between the main body portion of the windshield glass and the attachment portion of the windshield glass increases, and the movement amount of the collision object increases. For this reason, the impact mitigation performance against the colliding body that has collided with the windshield glass can be improved. Further, since the mounting portion formed at the end of the windshield glass in the vehicle width direction is directly fixed to the pillar frame member, the support rigidity of the windshield glass can be improved.
[0011]
According to a second aspect of the present invention, in the vehicle pillar structure according to the first aspect, the deformation resistance of the windshield glass mounting portion is provided in a space between the windshield glass mounting portion and the pillar frame member. Characterized in that it has a deformation resistance adjusting means for raising the resistance according to the amount of deformation.
[0012]
Therefore, in addition to the contents described in claim 1, the deformation resistance of the mounting portion of the windshield glass is changed by the deformation resistance adjusting means provided in the space between the mounting portion of the windshield glass and the pillar frame member. Can be raised accordingly. As a result, the impact mitigation performance against the collision body can be effectively improved.
[0013]
The pillar structure of the vehicle according to the third aspect of the present invention includes a pillar skeleton member forming a skeleton of the pillar;
Windshield glass mounting means connected to the vehicle width direction end of the windshield glass, and the vehicle width direction outer side bent toward the vehicle rear diagonally outward,
And a vehicle width direction outer end portion of the windshield glass mounting means is fixed to the pillar frame member.
[0014]
Therefore, the windshield glass mounting means, whose outer side in the vehicle width direction is bent obliquely toward the rear of the vehicle, is connected to the end of the windshield glass in the vehicle width direction, and the outer side in the vehicle width direction of the windshield glass mounting means is connected. Since the ends are fixed to the pillar skeleton member, a space is formed between the windshield glass and the pillar skeleton member that bears the strength and rigidity of the pillar. As a result, when the collision object collides with the windshield glass, the deformation stroke of the windshield glass and the windshield glass attaching means increases, and the movement amount of the collision object increases. For this reason, the impact mitigation performance against the colliding body that has collided with the windshield glass can be improved. Further, since the windshield glass attaching means connected to the end of the windshield glass in the vehicle width direction is directly fixed to the pillar frame member, the support rigidity of the windshield glass can be improved.
[0015]
According to a fourth aspect of the present invention, in the pillar structure of the vehicle according to the third aspect, the deformation resistance of the windshield glass mounting means is deformed in a space between the windshield glass mounting means and the pillar frame member. It is characterized by having a deformation resistance adjusting means for increasing the deformation resistance according to the amount.
[0016]
Therefore, in addition to the contents described in claim 3, the deformation resistance of the windshield glass mounting means is changed according to the amount of deformation by the deformation resistance adjusting means provided in the space between the windshield glass mounting means and the pillar frame member. Can be raised. As a result, the impact mitigation performance against the collision body can be effectively improved.
