Description

[Detailed Description of the Invention] The present invention relates to an automobile door in which the door panel is reinforced.

In general, car doors, like other car body parts,
Relatively thin steel plates are used to reduce vehicle weight.

For this reason, various reinforcement measures have been taken for this type of door so that it can sufficiently withstand the impact force at the time of a collision.

For example, as seen in Japanese Utility Model Application Publication No. 49-20220, there is a door panel in which a reinforcing space with a closed cross section is formed at the upper ends of both the outer panel and the inner panel forming the door panel.

However, although this alone ensures the strength of the upper end of the door panel, the strength of the central part, which makes up most of the door panel, is insufficient, and the impact force during a collision causes the central part of the door panel to move toward the passenger compartment. There is a risk of deformation.

The present invention has been developed in view of these circumstances, and an object of the present invention is to provide an automobile door that can ensure uniform strength of the entire door panel and is resistant to impact forces during a collision.

In order to achieve this object, the present invention is characterized by being constructed as follows.

That is, a door panel having a space inside is formed by joining an outer panel and an inner panel formed into a desired shape, and a door glass that is driven up and down by a window regulator is arranged between the outer panel and the inner panel. An upper reinforcing member is attached to the upper part of the inner panel in the door panel along the longitudinal direction of the vehicle body, and a glass guide that guides the door glass in the vertical direction follows the vertical trajectory of the outer panel and the door glass. The upper part of the door panel is connected to the upper part of the outer panel, and the lower part of the door panel is connected to a lower reinforcing member arranged at the lower part of the door panel. According to this configuration, the initial load at the time of a collision is shared by the glass guide arranged vertically inside the door panel, and is then absorbed by the upper reinforcing member attached to the upper part of the inner panel, thereby absorbing the impact force. A strong door can be obtained, the strength of the entire door panel can be ensured uniformly, and local deformation of the door panel can be suppressed.

Hereinafter, one embodiment of the present invention will be specifically described based on the drawings.

FIG. 1 shows a cross-sectional view of an automobile door, with reference numeral 1 indicating a door panel and reference numeral 2 indicating a door glass.

The door panel 1 is formed by joining an outer panel 3 and an inner panel 4 press-molded into a desired shape at both ends and a lower end to form a desired space 5 inside.

On the other hand, the door glass 2 is interposed between the outer panel 3 and the inner panel 4 of the door panel 1, and is driven up and down in the vertical direction by a window regulator disposed inside the door panel 1.

By the way, reinforcing plates 6 and 7 are provided at the upper and lower parts of the door panel 1, respectively.

The reinforcing plate 6 has a trapezoidal cross section and is attached to a bent piece 8, which is formed by folding the upper end of the outer panel 3 inward, along the longitudinal direction of the vehicle body. A pair of adjustment bolts 1 are attached to the bent piece 8 and the reinforcing plate 6 at a predetermined interval.

Bracket 1 for installing glass guide on the through end of
1 and 11 are screwed on. Also this bracket 1
A coil spring 12 is interposed between the adjustment bolt 10 and the reinforcing plate 6. The coil spring 12 is wound around the adjustment bolt 10. Note that this coil spring 12 may be omitted.

On the other hand, the reinforcing plate 7 has a substantially Z-shaped cross section and is attached to the inner surface of the lower bent portion 13 of the inner panel 4 along the longitudinal direction of the vehicle body. A reinforced space 15 with a closed cross section is surrounded by the reinforcing plate 7 and the inner panel 4. Note that this reinforcing plate 7 may be provided only at the glass guide mounting portion. Further, a pair of adjustment bolts 1 are installed on the reinforcing plate 7 at a predetermined interval.
6, 16 through the adjustment bolts 16, 16.
Bracket 1 for installing glass guide on the through end of
7 and 17 are screwed together, and a coil spring 18 is interposed between the bracket 17 and the reinforcing plate 7 by winding it around the adjustment bolt 16. Note that this coil spring 18 may be omitted.

Then, with a pair of glass guides 19, 19 for guiding the door glass 2 in the vertical direction separated by a predetermined interval, their upper and lower ends are connected to the brackets 11, 11 and 17, 17, respectively.
The glass guide 19 is fixed to the glass guide 19 by welding or the like.
19 is arranged in the vertical direction between the outer panel 3 and the vertical locus drawn by the vertical movement of the door glass 2.

The glass guides 19, 19 are cylindrical with a rectangular cross section and have an opening 19a on one side, as shown in FIG.
5 is inserted through the opening 19a, and a guide roller 26 rotatably supported by the tip of the support shaft is brought into rolling contact with the glass guides 19, 19.

As shown in FIG. 4, the door glass 2 has an X-link shaped wind regulator 41 attached to a glass holder 40 attached to the lower part of the door glass 2, and this window regulator 41 is rotated by a regulator handle 42. It moves up and down. At that time, the roller 2 attached to the door glass 2 via the bracket 43
6 rolls within the glass guide 19.

Further, the notches 20 provided in the bent piece 8 and the reinforcing plate 6 are for passing the glass guide 19 and the bracket 11 when the glass guide 19 is attached. Further, as shown in FIG.
This is a working hole provided for inserting a tool or the like when screwing the bolt onto the bracket 17 or adjusting the tightening force of the adjusting bolt 16.

A reinforcing plate 22 having a trapezoidal cross section along the longitudinal direction of the vehicle body is joined to the bent piece 21 obtained by bending the upper end of the inner panel 4 inward, and a reinforcing plate 23 having a substantially U-shaped cross section is further attached to the reinforcing plate 22. By joining, the reinforcing plate 23 and the reinforcing plate 22 create a space 24 with a closed cross section.
The upper reinforcing member 30 is constructed by forming the upper reinforcing member 30.
Further, the back surface of the upper reinforcing member 30 is brought into contact with the inner surface of the inner panel 4 via a filler 31.

According to such a configuration, the door panel 1 includes a pair of glass guides 19 bridging the reinforcing plates 6 and 7 of the door panel 1 at a predetermined distance from each other.
19, the initial load acting on the center of the outer panel of the door during a collision is shared by the glass guides 19, 19, and then the upper reinforcing member 30 provided at the top of the inner panel is shared.
Since the impact force is absorbed by the impact force, it is possible to obtain a door that is resistant to impact force.

In addition, since the entire door panel 1 is reinforced almost uniformly in the horizontal and vertical directions by the reinforcing plates 6 and 7 and the glass guides 19 and 19, the door panel 1 is partially strengthened by the impact force at the time of a collision. Deformation toward the room can be suppressed.

In addition, a reinforcing plate 6 provided at the upper end of the outer panel 3
It goes without saying that the upper end of the outer panel 3 will be further strengthened if a space with a closed cross section is formed in the same manner as the upper reinforcing member 30 provided on the inner panel 4 side.

As detailed above, according to the present invention, an upper reinforcing member is attached to the upper part of the inner panel in the door panel along the longitudinal direction of the vehicle body, and a glass guide that guides the door glass in the vertical direction is connected to the outer panel and the door glass. The upper part is connected to the upper part of the outer panel, and the lower part is connected to the lower reinforcing member installed at the lower part of the door panel. Therefore, the initial load that will be applied in the event of a collision will be The impact is absorbed by the glass guide, and then absorbed by the upper reinforcing member attached to the upper part of the inner panel, making it possible to obtain a highly safe automobile door that is resistant to impact forces.
