DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile door structure.

[0002]

2. Description of the Related Art Conventionally, there is an automobile door structure in which a door reinforcing beam is inserted into a door in the front-rear direction to improve the side strength of the door.

[0003] In such a vehicle door structure, for example, a flat cover member is additionally provided immediately above a door lock assembly provided in the door to prevent theft of the vehicle.

[0004] With such a cover member, one end of the locking lever of the door lock assembly is directly operated by a special member such as a steel gauge inserted through the door waist opening to release the unlocked state. I was trying to prevent that.

[0005]

By the way, in the above-mentioned door structure for an automobile, a door lock assembly is provided near the door lock assembly.
Since not only the door reinforcing beam but also the above-mentioned covering members are gathered, it is difficult to assemble the door lock assembly and its rods.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a vehicle door structure which has a simple structure and can easily be assembled with a door lock assembly and the like. .

[0007]

According to the present invention, in order to achieve the above object, in a door structure for an automobile in which a door reinforcing beam is inserted into a door in the front-rear direction, the door reinforcing beam is formed by connecting a pipe material. Forming a recess by crushing an end of the door reinforcing beam on the door lock assembly side,
A key cylinder control rod or a door safety lock rod connected to a door lock locking lever of the door lock assembly is located in the recess, whereby the door of the door lock assembly is moved by the pipe-shaped body of the door reinforcing beam. The lock locking lever is configured to cover the upper side.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a door structure for an automobile according to the present invention.

FIGS. 1 to 6 show an embodiment of the present invention. In the vehicle door structure of this embodiment, a door reinforcing beam 3 is inserted in the door 2 of the vehicle 1 as shown in FIG.

The door reinforcing beam 3 is formed using a pipe material, and has a recess 4 formed by crushing one end 3a.

The door reinforcing beam 3 is provided at both ends 3 so as to be located slightly above the door lock locking lever 6 of the door lock assembly 5 disposed in the door 2.
a and 3b are fixed to the door 2 by welding via a bracket 7 (only one is shown).

In the recess 3a of the door reinforcing beam 3, a door lock locking lever 6 of a door lock assembly 5 is provided.
A key cylinder control rod 8 communicating with a key cylinder (not shown) from one end 6a is located.

Thus, the one end portion 6a of the door lock locking lever 6 of the door lock assembly 5 is covered upward by the pipe-shaped main body 3c of the door reinforcing beam 3.

In order to more reliably cover the door lock locking lever 6 with the pipe-shaped main body 3c,
Use the door reinforcement beam 3 as much as possible to the door lock assembly 5
It is preferable to extend to the side.

With the above structure, one end 6a of the door lock locking lever 6 of the door lock assembly 5 is inserted into the door waist opening 9 by the pipe-shaped main body 3c of the door reinforcing beam 3 (FIG. 1). (Not shown) to prevent the unlocked state from being operated directly.

Further, in this embodiment, since one end 3a of the door reinforcing beam 3 is crushed, it is not necessary to replace the key cylinder control rod 8 of the door lock assembly 5 with a special one, which is economical. .

Further, since the door reinforcing beam 3 is formed of a pipe material, the door lock assembly 5 is not hindered when the door lock assembly 5 is assembled, so that the work can be performed smoothly.

Furthermore, in the present embodiment, the door reinforcing beam 3 can be formed sufficiently long, so that the strength of the door 2 against the compressive load in the front-rear direction can be improved.

Next, the function of the door lock locking lever 6 of the door lock assembly 5 will be briefly described.

The door lock assembly 5 has a latch (not shown) which is engaged with a striker (not shown) provided on the vehicle body when the door 2 is closed. It has a door lock open link lever 9 for releasing the latch.

Further, the door lock assembly 5 has a door lock open link 10 which is pushed down by operating a door outside handle (not shown).

In FIG. 4, when the door lock locking lever 6 is in the state shown by the solid line, it is in the so-called door unlock state where the latch can be released by operating the door outside handle, and is shown by the dotted line. If so, the door is locked.

When the door lock locking lever 6 is in the door unlocked state, as shown in FIG. 5, the overhang portion 10a of the door lock open link 10 is on one end 9a of the door lock open link lever 9. ,
When the door lock open link 10 is lowered, one end 9a of the door lock open link lever 9 is pushed down, the door lock open link lever is rotated in the direction of arrow A, and the latch is released.

Further, the door lock locking lever 6 is
For example, when operated by a key cylinder (not shown) and brought into the state shown by the dotted line in FIG. The door lock open link lever 9 is located at a position shifted from the one end 9a even if the door lock open link 10 is lowered.
Cannot be pushed down. Therefore, the door lock open link lever is not rotated in the direction of arrow A, and the latch is not released.

[0025]

As described above, according to the automobile door structure of the present invention, in the automobile door structure in which the door reinforcement beam is inserted in the door in the front-rear direction, the door reinforcement beam is piped. A key cylinder control rod or door safety connected to a door lock locking lever of a door lock assembly is formed by crushing an end of the door reinforcing beam on the door lock assembly side. Since the tail lock rod is located and the door lock rocking lever of the door lock assembly is covered upward by the pipe-shaped main body of the door reinforcing beam,
The door lock locking lever is directly operated by the special member inserted from the door waist opening by the pipe-shaped main body of the pipe material without using a specially prepared separate ket or the like, and the unlocked state is released. You can prevent that.

Further, since the door reinforcing beam has a structure in which one end is crushed, the structure is simple, the implementation is easy, and the economical advantage is great.

Further, since the door reinforcing beam is formed of a pipe material, the operation can be smoothly performed without hindering the assembly of the door lock assembly.

Further, in the present invention, if the door reinforcing beam is formed sufficiently long, the strength of the door against the compressive load in the front-rear direction can be improved.

In addition, according to the present invention, since the door reinforcing beam is made of a pipe material and one end thereof is crushed,
Since the structure is simple, it can be easily implemented without changing the component configuration inside the door, and it can be used not only to reinforce the door but also to prevent theft of the vehicle. In addition, economic benefits are great.
