Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door structure of a vehicle, and more particularly to a double door type or slide type door structure.

[0002]

2. Description of the Related Art A double door type vehicle door provided with an upper lock on the upper side opposite to the hinge side of the door and a lower lock on the lower side is disclosed, for example, in Japanese Patent Laid-Open Publication No.
-44075. In such a door, as shown in FIGS. 8 to 10, the pillar reinforcement 3 joined to the inner panel 7 at the lower part of the door.
0, the back surface of the L-shaped lower lock reinforcement 40 is joined to the lower lock reinforcement 40.
The lower lock 6 was installed on the horizontal surface of the vehicle. Reference numeral 2 indicates an outer panel.

As shown in FIG. 6, a control link and a cancel lever 10 for connecting the outer handle 8 and the inside handle 9 to the upper lock 5 and the lower lock 6 are connected to a door inner panel (not shown) for the door outer panel 2. As shown in FIG. 11, a lock control link bracket 11 for supporting the relay member 12 has a structure in which only one end is fixed to a pillar reinforcement 30 joined to the inner panel 7 as shown in FIG. .

[0004]

In the above conventional structure,
The lower lock reinforcement 40 tends to peel off due to the load in the door closing direction, and the strength around the lower lock 6 at the lower part of the door is insufficient, and the lower lock 6 is adversely affected by the deformation of the lower lock reinforcement 40 due to rollover. There is a possibility that it will.

[0005] Further, the rigidity of the lock control link bracket 110 is also low at the portion thereof, which adversely affects the degree of closing of the door. Further, since the upper part of the pillar reinforcement 30 is open at the lower part of the outer handle 8, water entering from the outer handle 8 directly drops on the lower lock 6, and the lower lock 6 may be rusted or frozen at low temperatures. was there.

SUMMARY OF THE INVENTION An object of the present invention is to provide a double door type vehicle door structure in which the strength and rigidity of the lower lock periphery and the lock control link bracket at the lower portion of the door are improved and the lower lock is prevented from rusting or freezing. is there.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a door of a vehicle having an upper lock on an upper side opposite to a hinge side of a door and a lower lock on a lower side. A pillar reinforcement of a three-sided wall having a hat-shaped cross section provided on the opposite side, and a longitudinal section having three surfaces in contact with the inside of the three-sided wall at the lower end of the pillar reinforcement and a horizontal plane on which the lower lock is installed. An L-shaped lower lock reinforcement having three faces joined together by three walls.

Further, the pillar reinforcement or the pillar reinforcement and the lower lock reinforcement are fixed to a door inner panel.

Further, the upper portion of the pillar reinforcement is joined to the door inner panel at least below the outer handle.

One end of the lock control link bracket is fixed to one end surface of the pillar reinforcement, and the other end of the lock control link bracket is attached to the door inner panel together with the other end of the pillar reinforcement. It is characterized by being fixed.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a double door type door, and reference numeral 2 denotes a door outer panel. Reference numeral 3 denotes a pillar reinforcement, which is joined to the door inner panel, not shown, on the side opposite to the hinge side of the door 1. 5 is an upper lock, 6 is a lower lock, 8
Denotes an outer handle for opening and closing the upper lock and the lower lock 6.

In the present invention, as shown in FIGS. 2 and 3, the pillar reinforcement 3 is a three-faced wall having a hat-shaped cross section composed of both side walls 3a and 3b and a back wall 3c. At the lower end of the side walls 3a, 3
b, both sides 4a, 4b and the back surface 4c, which are in contact with the inside of the back wall 3c, and a horizontal surface 4d on which the lower lock 6 is installed.
This is a structure in which a lower lock reinforcement 4 having an L-shaped vertical section and joined by three walls.

As shown in FIG. 3, the pillar-shaped reinforcement 3 having the hat-shaped cross section is fixed to the door inner panel 7 by a flange corresponding to a hat-shaped flange. still,
Although not shown, the lower lock reinforcement 4 joined to the pillar reinforcement 3 on three sides.
May be fixed to the door inner panel 7 together with the pillar reinforcement 3.

The upper part 3d of the pillar reinforcement 3 is joined to the door inner panel 7 at least below the outer handle 8 as shown in FIG.
The d prevents water entering from the outer handle 8 from dropping directly to the lower lock 6.

Further, as shown in FIG. 6, a not-shown door inner panel 7 for the door outer panel 2 is provided with a control link and a cancel lever 10 for connecting the outer handle 8 and the inside handle 9 to the upper lock 5 and the lower lock 6. Lock control link bracket 11 for supporting connected relay member 12
And its one end via a coupling member 13 secured to one edge of the pillar reinforcements 3, the other end that is fixed to the door inner panel 7 together with the other end of the pillar reinforcements 3 is there.

Since the present invention has the structure as described above, first, the structure around the lower lock 6 at the lower part of the door is a pillar reinforcement having a hat-shaped cross section composed of both side walls 3a, 3b and a back wall 3c. 3 and a horizontal plane 4 on which the lower lock 6 is installed.
The structure in which the lower lock reinforcement 4 having an L-shaped vertical cross section having d is joined by three walls has a closed cross section, so that the strength around the lower lock 6 is improved, and accordingly, the door closing property is improved. Further, the load acts in the direction of the shearing surface against the load in the door closing direction, and peeling of the lower lock reinforcement 4 is prevented.

The upper part 3d of the pillar reinforcement 3 is joined to the door inner panel 7 at least below the outer handle 8 so that water entering from the outer handle 8 does not drop directly onto the lower lock 6 by the upper part 3d. The structure prevents the lower lock 6 from rusting and freezing at low temperatures.

Further, the lock control link bracket 11 has one end fixed to one end face of the pillar reinforcement 3 via a connecting member 13 and the other end fixed to the other end of the pillar reinforcement 3. With the structure fixed to the door inner panel 7, the rigidity is improved even at the position of the lock control link bracket 11, thereby improving the closeability of the door and ensuring the assemblability of the lock control link bracket 11. .

[0019]

As described above, according to the present invention, there is provided an advantage that it is possible to provide a door of a double door type vehicle door without a center pillar, which has the advantage of solving the problems of the conventional structure. are doing.
