[Detailed description of the invention] A. Industrial application field The present invention relates to an automobile door opening device for unlocking a door lock device, and is particularly improved to prevent water droplets falling from a key cylinder from scattering on the door lock device. It is.

B. Prior Art A door lock device unlocks a door in response to the operation of a key cylinder attached to the door outer panel or an external handle protruding outward from the vehicle body also attached to the door outer panel. Movement of the cylinder and the external handle is transmitted to the door locking device via a transmission member. This door lock device is installed inside the door at a location below the location where the key cylinder and external handle are attached, but it is susceptible to water entering the inside of the door outer panel from outside the vehicle body. If water enters the door lock device, rusting, freezing, etc. may cause the lock to fail or be unable to be unlocked, so conventional measures have been taken to prevent water from entering the door lock device.

What was disclosed in Utility Model Application Publication No. 60-22981 is
By cutting the lower end of the seal lip of the glass run diagonally, water that has passed through the glass run and entered the inside of the door outer panel is prevented from splashing onto the door lock device.

C. Problems that the invention aims to solve By the way, key cylinders generally have a drain hole that drains water that has entered the interior through the shutter opening into which the key is inserted, to the outside. If there is a cylinder, there is a risk that water droplets falling from the water drain hole of the key cylinder may directly hit the door lock device, enter through the transmission member mentioned above, or fall and splash onto various parts. There is. However, what is disclosed in the above-mentioned publication does not take into account water that enters from such a route, and water may enter the door lock device depending on the positional relationship between the key cylinder and the door lock device. be.

SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle door opening device that eliminates the above-mentioned problems by receiving drainage water from a key cylinder in a saucer provided on an external handle.

D. Means for Solving Problems In order to achieve such an objective, the present invention includes a key cylinder attached to the door outer panel, an external handle for opening the door attached to the lower part of the key cylinder, and a key cylinder or In an automobile door opening device in which a door lock device for controlling the opening and closing of the door in response to the operation of the external handle is provided near the external handle, the external handle extends downward from its rotation axis and is connected to the outside of the door outer panel. It has an operating part that protrudes from the inside of the door outer panel above the rotation axis and a mounting part that can rotate together with the operating part, and a saucer is attached to the mounting part at the position where water drops from the key cylinder fall. At the same time, the saucer is arranged obliquely with its lower end located above the inner surface of the door outer panel, and a drain hole is provided at the lowest part of the door.

E Function Water that has entered the key cylinder is drained from the water drain hole and falls into the saucer attached to the external handle attachment. The water that has fallen into the saucer flows out so as not to touch the door lock device, flows downward along the door outer panel, and is drained from the drain hole at the bottom of the door.

F. Embodiment FIGS. 1 and 2 show an embodiment in which the present invention is applied to a back door. Reference numeral 1 designates a door outer panel, to which a key cylinder 3 is attached via a retainer clip 5. Drain holes 31 and 32 are formed on the outer peripheral surface of the key cylinder 3 and communicate with the inside of the key cylinder 3 and the shutter opening 33 into which the key is inserted. A door external handle device 7 is attached below the key cylinder 3. The door external handle device 7 is
It has a mounting base 71, a rotating shaft 72 installed on the base 71, and an external handle 73 rotatably attached to the rotating shaft 72, and mounting bolts 711, 71 fixed to the mounting base 71.
The door external handle device 7 is attached to the door outer panel 1 by inserting the handle 2 into the attachment hole of the door outer panel 1 from the outside and screwing nuts onto the attachment bolts 711 and 712 from the inside. The external handle 73 has an operating portion 731 that extends downward from the rotating shaft 72 and projects to the outside of the door outer panel 1, and a mounting portion 732 that projects inside the door outer panel 1 above the rotating shaft 72. Mounting part 73
2, a receiving tray 74 is removably fitted with an insertion portion 742. This external handle 73 is connected to the rotating shaft 72.
It is always biased toward the door outer panel 1 by a spring 75 (FIG. 2) attached to the door outer panel 1. here,
The saucer 74 is the water drain hole 31, 32 of the key cylinder 3.
is located directly below. And this saucer 74
is assumed to have enough weight to function as a counterweight for the operation part 731,
For example, it may be made of lead or the like, and the insertion portion 742 may be made of an elastic material such as rubber and bonded. In FIG. 1, reference numeral 8 indicates a handle cover, and reference numeral 9 indicates a seal rubber that is provided on the attachment base 71 and seals the insertion hole of the attachment portion 732 drilled in the door outer panel 1.

11 is a door lock device attached to the door inner panel 13, and a lever 15 is provided below the key cylinder 3 and engages with a striker fixed to the vehicle body (not shown) to operate a latch that locks the door. , 17, and 19, the lever 19 is connected to the key cylinder 3 by the rod 21, and the lever 17 is provided at a position where it can engage and come into contact with the tip of the attachment portion 732 of the external handle 73. That is, when the door is locked with the key cylinder 3,
The lever 17 is retracted from the rotation locus of the tip of the mounting portion 732 to the position shown by the two-dot chain line in FIG. 1, so that even if the external handle 73 is operated, the operating force is not transmitted to the door lock device 11 .

In the automobile door opening device configured in this way, water that has entered the key cylinder 3 through the shutter opening 33 of the key cylinder 3 is discharged from the water drain holes 31 and 32 and is drained into the saucer of the door external handle device 7. 74 falls on top. At this time, the saucer 74
As illustrated in FIG. 741 according to its inclination, and the inner surface 110 of the door outer panel 1
The water flows down through the water and is drained to the outside of the vehicle through a drain hole (not shown) provided at the bottom of the door. Therefore,
Water does not directly splash on the door lock device 11, and water droplets do not splash on the door lock device 11 indirectly, thereby preventing lock failures caused by rusting, freezing, etc.

Furthermore, if the operating part 731 of the external handle 73 is heavier than the mounting part 732, the center of gravity of the external handle 73 will move downward from the rotating shaft 72. Therefore, in the event of a collision, the external handle 73 will be moved in the direction of the arrow in FIG. A large inertial force may be applied to rotate the door, which may cause the door to open. Conventionally, a counterweight is provided above the rotation axis 72 to bring the center of gravity of the external handle 73 as close to the rotation axis as possible to reduce the inertia force. Since the mounted saucer 74 functions as a counterweight, the conventionally required counterweight can be omitted and the number of parts can be reduced. Although the operating force of the external handle 73 is transmitted to the door lock device 11 via the mounting portion 732, the member for transmitting the operating force is not connected to the mounting portion 7.
32 may be provided on the external handle 73.

Furthermore, in this embodiment, it is only necessary to fit the insertion portion 742 of the saucer 74 into the attachment portion 732 and attach it.
The installation work can be easily performed through the work hole drilled in the door inner panel 13. Further, there is no need to drill holes in bolts and nuts for mounting the saucer or on the door outer panel, and furthermore, there is no need to significantly change the design of other parts. Here, the saucer 74
It does not depart from the present invention even if it is screwed onto the mounting portion 732.

In addition, although the case where the door opening device based on this invention is used for a back door was demonstrated above, it can also be used for other doors.

G. Effects of the invention According to the invention, water droplets drained from the water drain hole of the key cylinder are allowed to fall onto a saucer provided at the attachment part of the external handle, and the water is drained along the door outer panel. Since the door lock device is not covered with water, water does not enter the door lock device, and lock failure due to rusting and freezing can be prevented. Furthermore, since the saucer functions as a counterweight for the external handle, there is no need to separately provide a counterweight, contributing to cost reduction.
