DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle door structure such as a front door or a rear door, and particularly relates to an improvement of a vehicle door structure equipped with a door guard bar that improves the side strength of a vehicle body.

Conventionally, as this type of vehicle door structure, NISSAN
Service bulletin August 1978 No. 340 (SK-
1) There is something shown on pages 217 to 219 of Skyline. Taking a front door as an example, the front door D has a door outer panel 1a and a door inner panel 1b forming a door body 1 in which a door window glass 2 is housed, as shown in FIGS. 1 and 2. A door lock device R that engages with a striker (not shown) provided on the vehicle body side is built into the rotatable free end of the door body 1, and a door guard bar G is provided inside the door body 1 along the longitudinal direction of the vehicle body. The door guard bar G exerts a predetermined bending strength in the event of a side collision, absorbs impact energy, and ensures the safety of the occupants. The door guard bar G includes a beam 3 made of, for example, a high-tensile steel plate and having a hat cross-sectional structure with an appropriate number of threads, and is provided at both ends of the beam 3 and fixed by welding to the front and rear ends of the door body 1. It consists of brackets 4a and 4b made of mild steel. The door lock device R also includes rods 5, which are connected to an outside handle and an inside handle (none of which are shown).
6, and the locking plate 7 of the door lock device R is also provided with an operating rod 8 connected to a door lock knob (not shown).

However, in such a conventional vehicle door structure, the door guard bar G is disposed along the longitudinal direction of the door body 1 only to improve the side strength of the vehicle body. Since the door guard bar G was arranged independently of the door lock device R provided at the free rotation end of the door body 1, the door guard bar G was located inside the door body 1 and was not connected to the door lock device R.
The upper part of the door was used exclusively as a space for arranging the rod 5 connected to the outside handle and the operating rod 8 connected to the door lock knob. Therefore, there is no member between the door lock device R and the waist opening (not shown) of the front door D that blocks the two. By deforming the door body 1), the wire etc. can be inserted from the waist opening into the door body 1.
There is a risk that the locking plate 7 of the door lock device R may be unlocked by inserting the wire into the door and operating the locking plate 7 of the door lock device R using the wire or the like. As a result, even if the door lock device R of a vehicle parked in a parking lot or the like is set to the locked state, the door lock device R is unlocked by the above-mentioned operation, resulting in a vehicle theft accident. There is a possibility that

The present invention has been made based on the above-mentioned viewpoints, and an object of the present invention is to provide a door guard bar with a shielding plate that covers the upper part of the door lock device installed in the door body, thereby improving the door waist opening. To provide a vehicle door structure which prevents vehicle theft by making it impossible to unlock a door lock device from the door.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

In the first embodiment shown in FIG. 3, the basic structure of the front door D is the same as the conventional one.
A door lock device R is built into the rotatable free end of the door body 1, and a door guard bar G is disposed in the longitudinal direction of the vehicle body. A shielding plate 10 is provided to block the upper part of the vehicle.

This shielding plate 10 is a plate material having an inverted L-shaped cross section and having a mounting portion 10a at one end, and is located near the bracket 4b that constitutes the door guard bar G, that is, the free rotation end of the door body 1. The mounting portion 10a is attached to the side surface of the door outer panel 1a of the bracket 4b by spot welding, and is arranged so as to protrude toward the door inner panel 1b side. This shielding plate 10 is arranged so as to cover at least the locking plate 7 of the door lock device R above. The rod 5 connected to the outside handle and the operating rod 8 connected to the door lock knob are arranged on the side of the shield plate 10.

Therefore, according to the vehicle door structure according to this embodiment, when a wire or the like is inserted into the door body 1 from the door waist opening for the purpose of unlocking the door lock device R, the wire or the like is inserted into the door body 1 from the door waist opening. When the wire is inserted into the main body 1 to some extent, it comes into contact with the shielding plate 10 protruding from the door guard bar G, and the tip of the wire is blocked by the shielding plate 10 and reaches the locking plate 7 of the door locking device R. do not. For this reason, it becomes impossible to operate the locking plate 7 of the door lock device R using the wire, etc., and the door lock device R cannot be unlocked. As a result, theft of the vehicle is completely prevented. Ru.
Further, since the shielding plate 10 is spot welded to the door guard bar G, the spot marks are not directly exposed on the surface of the door outer panel 1a, and there is no risk of damaging the exterior appearance of the vehicle body.

Next, a second embodiment shown in FIG. 4 will be described.

In this example, unlike the first example,
The shielding plate 10 is integrally formed with a bracket 4b made of mild steel that can be drawn and is provided with an insertion hole 11 in the center thereof for a rod 5 connected to the outside handle.

Therefore, according to this embodiment, since the shielding plate 10 is integrally molded with the bracket 4b, it is possible to prevent the door lock device R from being unlocked without increasing the number of parts, and also to prevent the door lock device R from being unlocked. Even if the rod 5 from the device R and the shielding plate 10 are in a positional relationship that interferes with each other, the insertion hole 1
Since the rod 5 can be disposed through the door lock 1, there is no need to particularly consider the mounting position of the door lock device R.

In addition, in each of the above embodiments, the shielding plate 10 is
Although they are all made of metal, they are not necessarily limited to this; for example, as shown in FIG. 5, they may be made of synthetic resin and integrally molded. In this case, The bracket 4b may be secured to the bracket 4b by an integrally molded clip portion 12. Further, in the second embodiment, the shield plate 10 and the rod 5 from the door lock device R are
In the case where the rods 5, etc. are in a positional relationship that interferes with each other, an insertion hole 11 is formed in the shielding plate 10 to allow the rod 5, etc. to be inserted therethrough, but the invention is not necessarily limited to this embodiment. As shown in Figure 6,
A notch 13 or the like may be formed. Furthermore, the specific shape of the shielding plate 10 is not necessarily limited to that shown in the examples,
For example, as shown in FIG. 7, the shielding plate 10 is molded from synthetic resin or the like, and the holding portion 14 for holding the rod 5 and the like is formed integrally with the shielding plate 10 to ensure the retention of the rod 5. Of course, the design can be changed as appropriate. Furthermore, the location of the shielding plate 10 is also as follows:
It does not necessarily have to be disposed on the bracket 4b, but may be disposed on the beam 3 depending on the mounting position of the door lock device R. Further, it goes without saying that the specific structure of the door guard bar G is not limited to that shown in each of the above embodiments.

As explained above, according to the vehicle door structure according to the present invention, the door guard bar is provided with a shielding plate that covers the upper part of the door lock device installed in the door body, so that a wire etc. can be inserted through the door waist opening. Even if this happens, the tip of the wire or the like is blocked by the shielding plate and does not reach the locking plate of the door lock device, so there is no risk of the door lock device being unlocked by the wire or the like. For this reason,
Vehicle theft accidents caused by unlocking the door lock device from outside the vehicle can be completely prevented. Furthermore, since the above-mentioned shielding plate is placed so as to cover the upper part of the door lock device, there is little risk that rainwater, etc. that enters from the door waist opening will fall directly on the door lock device, thereby preventing the door lock device from rusting. I can do it.
