BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening structure of a trunk lid for preventing water from entering into the trunk lid.

[0002]

2. Description of the Related Art In general, a gutter is formed between the periphery of an opening portion of a trunk room of a vehicle and a trunk lid for draining rainwater and car wash water, and a side opposite to the outside of the vehicle with the gutter as a center, that is, A seal is provided on the trunk room side, and the gutter and the seal prevent water from entering the trunk room.

In order to increase the sealing performance with this type of structure, it is effective to optimize the material, shape, and structure of the seal portion and to set a wide drainage area. As disclosed in Japanese Patent No. 289114, there is provided a fitting portion d which is made of a resin material having rubber elasticity and which is fitted in an upper portion of a side wall c defining an opening b of a trunk room a in a watertight manner. A seal g having a lip f for seating the mating surfaces of the seals in a water-tight manner.
It is conceivable to improve the sealing performance and drainage performance by forming a drainage passage h in which rainwater is introduced from a gutter and discharged outside the vehicle body.

[0004]

However, when the vehicle stops on a downhill and the vehicle body tilts, as a result, the water surface rises above the sealing surface j as shown by a two-dot chain line i in FIG. Alternatively, when the amount of rainfall is large and the water surface rises as shown by a two-dot chain line k in FIG. 3, a portion having a low sealing pressure due to the influence of the water pressure (the sealing pressure changes due to manufacturing variations or the like). ), Water may enter the trunk room a. When the seal is fatigued or deteriorated, the amount of water that enters the trunk room a further increases, and it becomes difficult to maintain the waterproof function.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an opening structure of a trunk lid that can cope with leakage of a seal when the seal is deteriorated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 2, a trunk room 2 of the vehicle 1 is formed in a rear portion 3 of the vehicle. As shown in FIG. A seal 5 is interposed between the mating surface with the lid 3 to prevent water from entering the trunk room 2. A first gutter 6 and a second gutter 7 are sequentially arranged along the opening 4 of the trunk room 2 and on the side opposite to the trunk room 2 with the seal 5 as a center.

The first gutter 6 and the second gutter 7 are connected to each other by opening their side walls. The first gutter 6 and the second gutter 7 are formed by depressing the outer plate 11 constituting the vehicle body 10 downward in the direction of gravity on the side opposite to the trunk lid 3 side, and the first gutter 6 is deeper. , The second gutter 7 is formed shallower than the first gutter 6,
In this embodiment, the second gutter 7 is formed at a depth that allows overrun to prevent damage when the trunk lid 3 is closed. Further, the outer peripheral end 3a of the trunk lid 3 faces the inside of the first gutter 6, and the rainwater is interposed between the inner surface 7b on the vehicle outer side of the second gutter 7 and the outer peripheral end 3a of the trunk lid 3. An entrance 8 is formed, and rain water, car wash water, and the like are poured into the first gutter 6 via the second gutter 7.

The trunk room 2 of the lining 9 is
The first gutter 6 is bent so as to cover the outer surface thereof, and is stopped in the state of being overlapped.

On the other hand, the seal 5 has, at its base, a groove-shaped fitting portion 13 fitted to the upper part of the gutter wall 12 on the trunk room 2 side of the first gutter 6, and a trunk at the opposite side to the base. A lip 14 for elastically supporting the lower surface 3a of the lid 3 and between the fitting portion 13 and the lip 14 for cushioning an impact force when the trunk lid 3 is seated and for utilizing a reaction force thereof as a sealing force. The air chamber 15 is made of a rubber weather strip having a section formed therein, and is configured to be integrated by pushing the fitting portion 13 toward the upper end surface of the gutter wall 12 of the first gutter 6. However, preferably, as shown in FIG.
At the time of fitting, the fitting is flexible to the opposite side to allow the fitting, and at the time of disengagement, the elastically flexible member is restricted to restrict the disengagement of the fitting portion 13 so that the lip-shaped seal portions 16 are provided. , And it is desirable that the seal portions 16 improve the sealability and the integrity as much as possible.

In this case, of course, the fitting portion 13 may be filled with a liquid sealing material or a sealing material having adhesiveness to further improve the seal and the integrity. In order to prevent the car wash water from being directly supplied to the seal surface 17 and to prevent the outer peripheral end 3a of the trunk lid 3 from being damaged by overrun at the time of closing, the first The second gutter 7 is formed to be shallower than the gutter 6 and at a depth that allows overrun of the outer peripheral end 3 a of the trunk lid 3.

When the vehicle stops on a slope and the vehicle body tilts, the water level rises above the seal surface 17 between the seal 5 and the trunk lid 3, or the water level rises above the seal surface 17 during car washing or due to rainfall. In order to prevent this, the seal 5 is fixed in a watertight manner around the opening 4 of the trunk room 2 as described above, and the sealing surface 17 between the seal 5 and the trunk lid 3 is formed in a horizontal plane including the entrance 8. It is effective to position it as a reference.

In this case, by lowering the connection point between the second gutter 7 and the periphery of the opening 4, the sealing surface 17 between the seal 5 and the trunk lid 3 may be positioned above a horizontal plane including the entrance 8. Although it is possible to increase the capacity while keeping the gutter width constant, as shown in FIG. 1, the contact surface of the trunk lid 3 with the seal 5, that is, the seal surface 17, It is preferable that the sealing surface 17 is located above the horizontal plane including the entrance 8 by being depressed to the opposite side.

With such a configuration, the seal 5 has the opening 4
The sealing surface 17 between the trunk lid 3 and the trunk lid 3 is fixed above the water level stored in the gutter, and is kept in a submerged state to prevent water from entering the trunk room 2. Since the first gutter 6 and the second gutter 7 are in communication with each other, rainwater enters the first gutter 6 from the second gutter 7. Of course, the water levels of the first gutter 6 and the second gutter 7 are the same due to the mutual communication. When the vehicle is stopped on a downhill or when the water is increased, the water content of the first gutter 6 and the second gutter 7 overflows from the entrance 8 and is directly discharged to the outside of the vehicle, but the overflow surface is always sealed. It exists at a position lower than in the plane 17. For this reason, even if the seal 5 has a low pressure portion, it does not enter the trunk room 2 from a portion where the sealability is reduced.

In this case, in order to promote the introduction of rainwater into the first and second gutters 6 and 7 and the overflow from the first gutter 6 and the second gutter 7, at least the above-mentioned trunk lid 3 is required. It is desirable to form a second concave portion 18 which is depressed on the surface facing the first gutter 6 in the direction opposite to the direction of the depression.

[0020]

As apparent from the above description, according to the present invention, the following excellent effects are exhibited.

[0021] (1) Ru can also be prevented from entering the rainwater into the trunk room of the reduction of the sealing property when there is a lower part of the sealing pressure.

(2) The depth of the second gutter is formed to be shallower than the depth of the first gutter, and at the time of car washing, the force of the car washing water is weakened by the second gutter, and the car washing water is directly supplied to the sealing surface. Ru can be prevented put away the.

(3) When the trunk lid is closed, an upward concave portion is formed on at least the facing surface of the trunk lid facing the gutter, so that rainwater is introduced into the first and second gutters and the first and second gutters are formed. Ru can be used to facilitate the overflow from the second gutter.
