Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a vehicle door structure formed in a closed cross-sectional shape by a door inner panel and a door outer panel.

[Prior art] Conventionally, vehicle doors have been equipped with, for example,
As shown in Publication No. 28163, a door lock mechanism is provided which is activated in response to the operation of a door handle, and this door lock mechanism is configured to be locked and unlocked via a key cylinder that is normally operated by a key. ing.

On the other hand, in the event of a frontal collision of a vehicle, if the door deforms so that the door inner panel to which the door lock mechanism is attached and the door outer panel to which the door outer handle is attached are separated, the door lock mechanism and the door outer handle are connected. Since a load will be applied to the outer handle rod in the direction of releasing the locked state of the door lock mechanism, one end of the outer handle rod will be attached to the edge of the door inner panel near the door lock mechanism or its operating member in the door closing section. By installing a substantially L-shaped reinforcement whose other end is attached to the inner surface of the door outer handle, deformation of the door is prevented and the locked state of the door lock mechanism is released. There is something designed to prevent this.

[Problem to be solved by the invention] By the way, the above-mentioned door is equipped with a window glass that can be raised and lowered freely, and a weather shield is installed at the bottom of the window glass to prevent rainwater from entering the closed section of the door. Although a lip is provided, even with this weather strip, it is difficult to completely prevent rainwater from entering the closed section. For this reason, rainwater that has entered the closed section of the door drips from the lower end of the rear end of the window glass onto the door lock mechanism or its operating members, such as the key cylinder and outer handle operating member, and enters the interior thereof. However, there have been problems such as rust formation and the rainwater freezing in cold weather, making the key cylinder inoperable.

The present invention was developed to solve the above problems, and even if rainwater enters the closed section of the door, it effectively prevents this rainwater from having a negative impact on the key cylinder etc. The purpose of the present invention is to provide a vehicle door structure that can prevent this from occurring.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a door inner panel that is attached to the rear end of the closed section of the door formed by the door inner panel and the door outer panel. In a vehicle door structure in which a key cylinder is installed on the door outer panel and connected to the door lock mechanism via an operating rod, one end of the door lock mechanism is attached to the door inner panel in the vicinity of the key cylinder. A reinforcement is attached to one end face and the other end is attached to the inner face of the door outer panel, and this reinforcement has a notch in which the key cylinder is installed, and this notch is provided with a notch in which the key cylinder is installed. By raising the key cylinder, a water splash prevention part is formed that covers the upper part of the key cylinder.

[Function] As mentioned above, it is arranged near the key cylinder in the closed section of the door, and prevents the door from being pushed wide in the vehicle width direction and deformed so that the door inner panel and door outer panel are separated in the event of a frontal collision. To effectively prevent rainwater that has entered the closed cross section from dripping onto the key cylinder from the lower end of the rear edge of the upper window glass by forming a water splash prevention part on the reinforcement. I can do it.

[Example] Fig. 1 shows an example in which the door structure of the present invention is applied to a cab-over type vehicle. A door 1 of the vehicle is provided with a door outer handle 2 and a key cylinder 3 on the rear side, and above which a door lock knob 4 and a door lock mechanism 5 are provided. As shown in FIG. 2, the door 1 includes a door inner panel 6 and a door outer panel 7 made of press-formed steel plates, etc., and the peripheral parts of both panels 6 and 7 are integrated by hemming or other means. By being connected to, a closed cross section 8 is formed inside it.
is formed.

A substantially L-shaped reinforcement 9 for reinforcing the attachment portion of the door outer handle 2 is provided at the rear portion of the closed section 8 . This reinforcement 9 has one end attached to the rear end surface 6a of the door inner panel 6 with a bolt 10, and the other end extends along the door outer panel 7 and is fastened together with the door outer handle 2 with a bolt 11. It is attached to the inner surface of the door outer panel 7 by being attached to the inner surface of the door outer panel 7. As shown in FIGS. 3 and 4, a notch 12 is formed in the intermediate portion of the reinforcement 9, and faces the key cylinder 3 that is attached to the door outer panel 7 and projects into the closed section 8. By cutting and raising a part of this notch 12, a water splash prevention part 13 that covers the upper part of the key cylinder 3 is formed.

In addition, as shown in FIG.
a knob rod 14 connected to the door lock knob 4;
A key cylinder rod 15 connected to the key cylinder 3 via a key cylinder lever 3a, an outer handle rod 16 connected to the door outer handle 2, and an inner handle rod 18 connected to the door inner handle 18 are connected. has been done.
The door 1 is locked and unlocked by pressing the door lock knob 4 to lower the knob rod 14, or by turning the key to lower the key cylinder rod 15.

The upper part of the reinforcement 9 is provided with the windshield 1 when the windshield 19 is fully closed.
A glass holder 22 is attached to support the lower end of the glass holder 9 and prevent its vibration. Furthermore, a sealing launcher 21 is installed inside the door sash 20 that serves as a guide for raising and lowering the window glass. It is cut above it to prevent interference.

As described above, the vicinity of the attachment part of the door outer handle 2 is reinforced in the closed section 8 of the door 1, and the door is pushed wide in the vehicle width direction so that the door outer panel 7 and the door inner panel 6 are separated in the event of a frontal collision. A reinforcement 9 is provided to prevent the key cylinder 3 from being deformed by water splashing, and a water splash prevention part 13 is formed on the reinforcement 9 to cover the upper part of the key cylinder 3. Therefore, the door 1 can be easily constructed without increasing the number of parts. Rainwater that has entered the closed cross section 8 of the key cylinder 3 can be prevented from dripping onto the key cylinder 3.
That is, the closed cross section 8 is separated from the launch tube 21 part in the door sash 20 on which the window glass 19 slides.
The rainwater that has entered the interior drips onto the water splash prevention part 13 from the lower end of the lunch jacket 21 and is guided laterally along the water splash prevention part 13.
To surely prevent rainwater from dripping onto a key cylinder 3 even if there is a layout restriction such that the lower end of a launcher 21 cannot extend below the key cylinder 3 in order to prevent interference with the lower end of a glass holder. I can do it. Therefore, it is possible to effectively prevent rainwater from entering the inside of the key cylinder 3 and causing rust, or from freezing the rainwater in cold weather and rendering the key cylinder 3 inoperable. .

In addition, since the water splash prevention part 13 is formed by cutting and raising a part of the reinforcement 9, when a separate member is attached to the reinforcement 9 by means such as welding, It has the advantage of being easier to manufacture.

Furthermore, since the key cylinder 3 can be installed with the notch 12 of the reinforcement inserted through it, the key cylinder 3 and the reinforcement 9 can be installed at any desired position without interfering with each other. can do. Note that the notch 12 formed in the reinforcement 9
has a size corresponding to the external shape of the key cylinder 3,
The key cylinder 3 may be configured to be fitted into the notch 12, and in this case, the reinforcement 9 has the advantage that the inner part of the key cylinder 3 can be supported and its rocking displacement can be prevented. There is. In addition to the water splash prevention part 13 that covers the upper part of the key cylinder 3, the door outer handle 2
A water splash prevention part may be installed to cover the upper part of the operating member, or in a passenger car etc. in which the door lock mechanism 5 is installed below the key cylinder 3, a water splash prevention part may be installed to cover the upper part of the door lock mechanism 5. It is also possible to have a structure in which a section is installed.

[Effect of the invention] As explained above, the present invention has one end attached to the end face of the door inner panel and the other end attached to the door outer panel within the closed section formed by the door inner panel and the door outer panel. A reinforcement is provided, and a water prevention part is formed on this reinforcement to cover the upper part of the key cylinder or lock mechanism, etc.
This reinforcement has a reinforcing function that supports the load input from the door outer handle, etc. and the impact load in the event of a frontal collision, and also prevents rainwater that has entered the closed section of the door from dripping onto the key cylinder, etc. Since it has the function of preventing rainwater from dripping onto the key cylinder etc., it is possible to effectively prevent rainwater from dripping onto the key cylinder etc. with a simple configuration without increasing the number of parts. Therefore, the advantage is that it is possible to reliably prevent the key cylinder, etc. from rusting due to the influence of the rainwater, or from freezing the rainwater that has entered the interior, making it impossible to operate the key cylinder, etc. be.
