Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the opening/closing lid structure of an I-rank lid, a back door, etc. provided in an automobile.

Conventionally, this type of opening/closing lid includes, for example, a trunk lid as shown in FIGS. 1 and 2.

This trunk lid 1 has an outer panel 4 and an inner panel 5, and a peripheral edge portion 1a is rotatably attached to the vehicle body 2 via a hinge (not shown), and a trunk compartment 3, which is an opening in the vehicle body, can be opened and closed. There is. The peripheral edge 1b of the trunk lid 1 is connected to a weather strip 6 attached to the opening peripheral edge 2a of the trunk compartment 3 in the closed state.
The interior of trunk compartment 3 is sealed.

The state of contact at the rear peripheral edge portion 1c of the trunk lid l is as shown in FIG. 2, in which the rear outer panel 7 and the rear inner panel 8 form the rear portion of the opening peripheral edge portion 2a. The weather strip 6 attached to these flange portions 9 and the sealing surface 5a of the inner panel 5
are in contact with each other. On the other hand, the weather strip 6 is formed with a drain lip a whose tip abuts against the vehicle body 2 to prevent water from entering. A draining notch is formed at an appropriate location on the draining lip 6a.
A water drain bead is formed on the car body 2 (rear outer panel 7) below a, and the water in the weather trip 6 was drained from the water drain notch and water drain bead. . Incidentally, reference numeral 10 is a molding attached with a port 10a or the like for decoration.

However, in such conventional run lids 1 to 1, the rear end 1c of the peripheral edge extends downward for a long time to improve appearance and prevent water from entering, so the rigidity is weak and the rear end 1c of the periphery is weak when closed. If it is pushed or suddenly closed, there is a risk of it being elastically deformed and interfering with the rear panel 7, and if the weather strip 6 has deteriorated and its elasticity has weakened, the force supporting the 1-run grid 1 will be weak. In addition to the above, there is a problem that interference is even more likely to occur. In addition, if the area to which the weather strip 6 is attached is directly hit by water during a car wash, etc., water may flow back through the water drain notch or water drain bead, or the seal on the inner panel 5 may Side 5
If the contact condition with a is poor, there is a risk that water may enter through this gap and leak into the trunk room 3. moreover,
When the trunk lid 1 is closed, there is a problem in that since no air vent is formed, the air pressure in the trunk compartment 3 becomes high, making it difficult to close the trunk lid. In addition, the back door, which is another example of an opening/closing lid, has the same problems as above.
Furthermore, in addition to the problem of the difficulty in closing due to the increase in air pressure when closing, there is also the problem that the increase in air pressure in the vehicle interior causes discomfort to the occupants.

This invention was made by focusing on the conventional situation, and it prevents interference with the vehicle body when closing, forms an air vent to facilitate closing, and further improves the area where the weather strip is installed. To provide an opening/closing lid structure for an automobile which can prevent water from entering by not being directly hit by water.

Therefore, in the opening/closing lid structure according to the present invention, a communication hole is bored in an area outward from the rear sealing surface of the inner panel to communicate the inside of the car with the outside of the car in the closed state. The gist of the present invention is to provide an elastic member that abuts in the closed state, and to form a notch in the elastic member that connects the inside of the vehicle with the outside of the vehicle by offsetting the communication hole.

Hereinafter, the present invention will be explained based on examples.

In the following description, parts or members that are the same as or equivalent to those in the prior art are designated by the same reference numerals, and redundant description will be omitted.

FIGS. 3 and 4 are diagrams showing embodiments of the present invention.

First, the configuration will be described. The trunk lid 11 as an opening/closing lid according to the present invention is formed from an outer panel 4, an inner panel 15, and a molding 20, and its peripheral edge portion is pivotally attached to the vehicle body 2.

The outer panel 4 and the inner panel 15 are assembled by hemming their peripheral edges, and are separated from each other in the center. In this inner panel 15, a hole 15b is formed in the central part of the sealing surface 15a, that is, in a region facing the trunk room 3, and a communicating hole 15b is formed in the outer part of the sealing surface 15a on the rear side of the vehicle.
5c are drilled in several places. This communication hole 15c allows communication between the inside of the trunk room 3 and the outside of the vehicle via the hole 15b in the closed state. Furthermore, this communication hole 15
An elastic member 20a integrally formed with the molding 20 is provided outward from c, that is, on the rear end side, and is set to abut against the rear outer panel 7 in the closed state. The elastic member 20a is made of a soft resin or rubber material, and is provided from the left end to the right end in the vehicle width direction, and communicates the weather strip G side with the outside of the vehicle at a position offset from the communication hole 1jc. A notch 20b is formed. This notch 20b is formed to have a narrow width and to be inclined with respect to the vertical direction. On the other hand, the water draining lip 6a of the weather strip 6 is formed with the water draining notch 6b described in the conventional example at a position offset from the notch 20b of the elastic member 20a.

Next, to explain the operation, when the trunk lid 11 according to the present invention is suddenly closed, the peripheral rear end portion 11c is elastically deformed, but by providing the elastic member 20a, this elastic member 20a is 7, the trunk lid 11 and rear outer panel 7 do not come into contact with metal and are not damaged, maintaining their quality. In addition, when closing the weather strip 6 in a state where the weather strip 6 has deteriorated and its elasticity is weakened, or when closing, the peripheral rear end 11c
Even when pressed, the elastic member 20a comes into contact with the rear outer panel 7 in the same manner as described above, and of course, no damage occurs.

Furthermore, when the trunk lid 11 is closed, the air in the trunk compartment 3 passes through the hole 15b of the inner panel 15 and the communication hole 15c as shown by arrow A, and then passes through the notch 20b of the elastic member 20a and both sides in the vehicle width direction. The internal pressure inside the trunk 7m3 did not increase much,
The trunk lid 11 can be easily closed. By the way, in the case of a back door, the air pressure inside the vehicle does not rise that much, so it can be closed without causing any discomfort to the occupants.

On the other hand, when the car is washed or the like in the closed state, the elastic member 20a can prevent water from directly hitting the weather strip 6, preventing water from flowing back from the water drainage notch 6b of the drain lip 6a, or preventing the inner panel 15 from flowing back. Water is prevented from entering the tank room 3 without entering between the sealing surface 15a and the sealing surface 15a.

Note that the notch 20b formed in the elastic member 20a is narrow and inclined, and is offset from the draining notch 6b, so that the weather strip 6 is prevented from being directly hit by water passing through the cutout 20b. Of course, no water will get in. In addition, when water flows through the weather strips 6 located on the front side and on both sides in the vehicle width direction, and flows to the rear weather strip 6 shown in the figure, water drains from the water drain notch 6b to the outside of the weather strip 6. As shown by arrow B, the liquid flows through the rear outer panel 7 and is discharged from the vehicle through the notch 20b of the elastic member 20a.

Note that the opening/closing lid according to the present invention is not limited to the trunk lid 11 of the above-mentioned embodiment, but it goes without saying that the opening/closing lid according to the present invention may be a back door or other opening/closing lid. Further, the cutout portion 20b may be cut out in a crank shape or the like.

As explained above, according to the present invention, by providing the elastic member, it is possible to prevent water from directly hitting the weather strip, preventing water from entering the interior of the car, and preventing interference with the car body (metallic Touch) can be prevented and quality can be maintained without damage. Furthermore, since the air can be vented when the lid is closed, the opening/closing lid can be easily closed.
