Description

[Detailed description of the invention] The present invention relates to a drainage structure for a key cylinder.

Key cylinder cylinders such as vehicle doors and trunks are equipped with a shutter in the key insertion part to prevent water from entering, but when washing the car, brushes, etc. push the shutter open and water can enter the inside of the key cylinder. Therefore, water that has entered the key cylinder is drained out of the key cylinder through a drain hole provided at the bottom of the cylinder case, and then through a drain hole provided at the bottom of the vehicle body panel where the key cylinder is installed. ing. Figure 1 shows a conventional key cylinder drainage structure, in which a drainage hole is provided at the bottom of the cylinder case 2 of the key cylinder body 1, which is attached to the outer panel 6 of the back door D, which is a vehicle body panel, by a retaining clip 4. 3 is provided, and water that has entered the key cylinder body 1 is discharged from a drainage hole 11 provided at the lower end of the inner panel 7 of the back door D. In order to improve key insertion, the key cylinder is fixed at an angle so that the inside of the vehicle body is lower than the outside of the vehicle body, as shown in the figure, and the water drain hole 3 is fixed to the cylinder case 2.
Water that has entered the key cylinder body 1 is first drained from the water drain hole 3a provided at the bottom of the cylinder case 2 on the outside of the car body, and then drained there. Water that has flown down to the front of the key cylinder body 1 due to the inclination of the key cylinder body 1 due to the inclination of the key cylinder body 1 is discharged from a drain hole 3b provided at the bottom of the cylinder case 2 inside the vehicle body. However, in this key cylinder, the water discharged from the water drain hole 3a at the bottom of the outside of the vehicle body flows down along the outer panel 6 as shown by the arrow line and toward the drain hole 11, and there is no problem with this, but inside the vehicle body. Drain hole 3 at the bottom of the side
A part of the water discharged from b is guided by the key lever 5 attached to the tip of the key cylinder main body 1, hits the rod 8, and flows down the rod 8 to reach the lock release lever 10, the back lock 9, and the striker. There was a problem in that the particles penetrated into the interior of the vehicle through the pipe 12, wet the carpet, and caused corrosion of the interior components of the vehicle. (Refer to Japanese Utility Model Application Publication No. 55-47523.) The present invention was developed by focusing on these conventional problems, and has a structure in which the water discharged from the key cylinder is drained outside the vehicle without entering the interior of the vehicle. In addition, the key lever is formed to cover the axially inner part of the key cylinder and the outside edge of the lower part of the key lever is designed to reduce the number of installation steps without increasing the number of parts. A flange extending toward the vehicle body panel is provided on at least a portion of the key lever, and a guide portion for receiving water discharged from the water drain hole and guiding it toward the vehicle body panel is integrally formed at the lower part of the key lever.

Hereinafter, the configuration of an embodiment of the present invention will be described with reference to the drawings, using the same reference numerals for the same parts as in the prior art.

In FIGS. 2 and 3, reference numeral 1 denotes a key cylinder body, which is fixed to an outer panel 6 of a backdoor D by a retaining clip 4. As shown in FIGS.
Further, 3 is a water drain hole provided at the bottom of the cylinder case. Reference numeral 5 denotes a key lever made of a plate material such as resin, which is attached to the tip of the key cylinder body 1 at an angle of about 45 degrees to the left from the vertical direction when the back door D is closed in order to improve key operation. This key lever 5 has a guide portion 13.
are integrally molded. The guide portion 13 is formed on the lower end edge of the key lever 5 below the water drain hole 3, and includes a lower surface plate 13a facing downwardly to the outside of the vehicle.
and a side plate 13b formed over the lower plate 13a and the side edge of the key lever 5,
These key lever 5, bottom plate 13a and side plate 1
It has a receiving part 13c separated by 3b. 1
Reference numeral 1 denotes a drainage hole, which is provided at the lower end of the inner panel 7 of the back door D. Reference numeral 8 designates a release lever 10 for a back door lock 9, which is a vehicle functional component disposed inside the outer panel 6, and a key lever 5 attached to the tip of the key cylinder main body 1 located above the back door lock 9. are connected.

Next, the effect will be explained.

Some of the water that has entered the key cylinder body 1 is
Water drain hole 3a at the bottom of the cylinder case 2 outside the vehicle body
It is discharged from the drain hole 11 as in the conventional case. On the other hand, water discharged from the water drain hole 3b at the bottom of the inside of the cylinder case 2 flows down along the key lever 5 and the guide part 13 as shown by the arrow line in FIG. 6
When the flow rate is high, the flow rate is high and reaches the outer panel 6, flows down along the outer panel 6, and is discharged from the drain hole 11.Even when the flow rate is low, the dripping position is the same as the drain hole 11. Similarly, since the water is located near the drain hole 11, water is discharged outside the vehicle from the drainage hole 11 without entering the interior of the vehicle. Also,
Since the water drips from the lower end of the guide part 13, it is sufficiently far away from the rod 8 so that water does not splash onto the rod 8, and water does not infiltrate into the passenger compartment through the rod 8. Furthermore, since the water discharged from the water drain hole 3b is once received in the receiving portion 13c and then dripped toward the outer panel 6 side, a large amount of water will not forcefully enter the key cylinder body 1 when washing the car or the like. Even if the water is removed, this large amount of water can be reliably captured by the receiving portion 13c. Even if a large amount of water that has forcefully entered the key cylinder body 1 hits the key lever 5,
It does not splash in all directions and has a reliable function of preventing water from entering.

As explained above, the present invention includes arranging vehicle functional parts inside a vehicle body panel, and attaching a key cylinder body above which has a key lever at the tip and a water drain hole at the bottom. In the key cylinder drainage structure in which water discharged from the water drain hole is drained to the outside of the vehicle through a drainage hole provided at the lower end of the vehicle body panel, the key lever is connected to the interior side portion of the key cylinder in the axial direction. and a flange extending toward the vehicle body panel is erected on at least a portion of the outer edge of the lower part of the key lever, and the guide receives water discharged from the water drain hole and guides it toward the vehicle body panel. Since the key lever part is formed integrally with the lower part of the key lever, it has the following effects.

The key lever is formed to cover the inside of the vehicle interior in the axial direction of the key cylinder, so when washing the car, high-pressure water directly from the hose can be rotated not only against the water drain hole but also against the key cylinder case and this case. Since the ejected water is vigorously ejected toward the interior of the vehicle through the gap between the key cylinder and the key cylinder, it is possible to reliably prevent this ejected water from entering the interior of the vehicle.

Since the flanges (side plate 13b, bottom plate 13a) are installed upright, the water that gushes out will surely catch the water that tries to spread from side to side when it hits the key lever, and will make a U-turn and securely hit the vehicle body panel. Can be guided to the side.

Since the guide part is integrally formed at the bottom of the key lever, the installation part of the key cylinder body is a narrow space sandwiched between the inner panel and the outer panel, so it is difficult to install the guide member as a separate unit. This has the significant advantage of improving performance and reducing assembly man-hours.
