Description

[Detailed Description of the Invention] This invention relates to a device that prevents an automobile door from entering the passenger compartment when the door is hit from the side.

Conventionally, automobile doors include an inner door panel, an outer door panel, and a reinforcing member provided between these inner and outer panels.
In the event of a side collision, only the door hinge and locking device receive the impact force, which has the disadvantage that it is not possible to sufficiently prevent the door from entering the vehicle interior. In order to suppress the door from intruding into the vehicle interior, increasing the strength of the door can prevent it to some extent, but increasing the strength of the door generally results in an increase in weight.

This invention was made in order to eliminate the above-mentioned conventional drawbacks, and aims to provide a device that can prevent the door from intruding into the passenger compartment in the event of a side collision without increasing the weight of the door.

The automatic door compartment intrusion prevention device according to the present invention includes:
In order to increase the rigidity against lateral collision forces acting on the door, a reinforcing member with a corrugated cross section is attached to the door inner plate at both front and rear ends and is disposed inside the door in the front and back direction, and the reinforcing member is supported by the reinforcing member. a door hinge and a door lock device provided opposite to the front and back ends of the outer periphery of the door; a male member supported by the reinforcing member and protruding outward from appropriate locations on the outer periphery of the door and having an enlarged tip portion; It is provided at a position corresponding to the male member on the peripheral edge of the single side door opening and at a position corresponding to the axial tip of the transverse member of the vehicle body, and when the door moves further toward the vehicle interior from the closed position, a female member that engages the male member;
It is characterized by having the following.

According to the present invention, when a large impact force is applied in the lateral direction of the door, such as when another vehicle collides with the side of the door, this impact force is received at three points: the door hinge, the locking device, and the female member. Because it is curved, the impact force is dispersed. In particular, since the force acting on the female member is supported by the transverse member of the vehicle body, the impact force can be sufficiently resisted. Further, since a reinforcing member with a corrugated cross section is disposed inside the door, the bending rigidity against lateral loads is high, and deformation of the door is suppressed.

Embodiments of the present invention will be described below with reference to the drawings.

The reinforcing member 4 is connected by being welded to the side surface of the reinforcing member 4 that crosses the section, thereby forming a frame shape. As shown in FIG. 1, a door hinge 8 is connected to the front section 5, and a door lock device 9 is attached to the rear section 6.

The reinforcing member 4 has a corrugated cross section as shown in an enlarged view in FIG. 2, and its lower end is joined to the lower edge of the door outer panel 2 by folding. In addition, bolt holes 11 are provided at appropriate locations on the flat part 10 of the reinforcing member 4 exposed below the door.
A threaded portion 13 of a bolt 12 is inserted through this bolt hole 11.

As shown in FIG. 3, the bolt 12 includes the threaded portion 13 at the upper end, a shaft portion 14 having a larger diameter than the threaded portion 13 at the center, and an enlarged tip portion 15 having a larger diameter than the shaft portion 14 at the lower end. , a threaded portion 13 is attached from below to pass through the upper retainer 16 and the lower washer plate 17 of the flat portion 10, and a welding nut 18 is attached to the upwardly projecting portion of the threaded portion 13, and a welding nut 18 is attached to the shaft portion 14. The retainer 16, the washer plate 17, and the flat portion 10 are screwed together so as to be tightened, and are welded to the retainer 16 in the tightened state.

The length of the bolt 12 is such that when the automobile door 1 is closed, the enlarged end portion 15 is located slightly upwardly from the upper surface 21 of the locking outer panel 20 that constitutes the lower peripheral edge of the vehicle body side door opening 19. has been done.

As shown in FIGS. 3 and 4, a female member 22 is integrally attached to the upper surface 21 of the locker outer panel at a position corresponding to the bolt 12 when the automobile door 1 is closed.

This female member 22 is long in the front and back direction of the door and has a mounting bolt 23 and a welding nut 24 at its front and rear ends.
The outer panel top surface 21 and retainer 2
It is fixed in such a way as to sandwich 5. Further, the central portion of the female member 22 is received in such a way that when it is separated upward from the top surface 21 of the locking outer panel and the automobile door 1 is closed, it is at a height position intermediate between the flat portion 10 of the reinforcing member 4 and the top surface 21 of the locking outer panel. 26.

This receiving part 26 is provided with a notch part 27 in the direction from the door side at the center in the direction in which the door closes. This notch 27 is such that when the automobile door 1 is closed, the shaft portion 14 of the bolt 12 enters into this notch 27 from the right direction in FIG. Space is starting to take shape. In addition, the right side of the receiving portion 26 of the female member 22 in FIG.
can be located below the receiving portion 26.

Inside the vehicle body of the female member 22 is a locking inner panel 28 that is perpendicular to the locking outer panel 20.
The end of the cross member 29 is welded via the . Reference numeral 30 in the figure is a floor panel. 31 is a weather strip on the door side, 32 is a partition plate, and 33 is a scuff plate.

In this embodiment, when another vehicle or the like collides with the side surface of the automobile door 1, the automobile door 1 as a whole tries to enter the direction of the vehicle interior 34. At this time, the reinforcing member 4 resists the external force that deforms the door, and the shaft portion 14 of the bolt 12 integrally connected to the lower end of the reinforcing member 4 abuts the notch 27 of the female member 22, thereby deforming the female member 22. Through the locker outer panel 20, locker inner panel 28, and cross member 29, the door is prevented from intruding into the vehicle interior. In particular, since the cross member 29 is provided parallel to the moving direction of the automobile door 1, the movement of the reinforcing member 4 toward the interior of the vehicle is strongly suppressed.
