Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a seal structure between the hood and the roof opening of an automobile equipped with a hood that covers the roof opening.

[Conventional technology and problems to be solved]

Some four-wheel drive vehicles for off-road driving have a cargo platform behind the driver's cab, as well as a canopy that covers this cargo platform in the form of a box. Furthermore, there are some automobiles with a hood shown in Japanese Utility Model Application Publication No. 61-185614, etc., in which the roof opening of the driver's cabin is covered with a hood to match the loading platform. Such vehicles have an opening in the roof of the driver's cabin so that the driver can enjoy an open feeling when the top is removed, and a canopy that covers the roof opening can be removably attached to the roof. It is made possible. In addition, when attaching the canopy to the vehicle body, the part of the canopy that covers the cargo bed is usually
It is supported by the canopy ribs attached to the cargo bed, and its hem is fixed to the vehicle body by hooking it to the side frame of the cargo bed, etc., and the hem of the part of the canopy that covers the roof opening (front edge and both side edges) This is done by fixing the part) to the outer surface of the roof. By the way, in the case of such a car with a top, when the top is attached, make sure that there is a gap between the top and the car body to prevent rainwater from entering the cabin through the gap between the top and the car body. It is necessary to be able to seal it. In particular, since it is unacceptable for rainwater to enter the driver's cabin, it is necessary to construct a sealing structure with excellent sealing properties between the roof opening and the hood. Conventionally, there is a sealing structure between a roof opening and a hood as shown in FIG. In this conventional seal structure, a sealing member b such as a sponge is attached to the inner surface of the top a, and this sealing member b is configured to come into contact with the outer surface of the roof when the top is attached, thereby preventing rainwater from entering the roof opening c. It is designed to prevent intrusion. However, since the hood a is usually made of a lightweight and flexible sheet material, the seal structure described above does not provide a uniform and sufficient seal when bringing the seal member b into contact with the outer surface of the roof. Therefore, there is a problem in that it is difficult to reliably prevent rainwater from entering the roof opening. Particularly, when water is vigorously sprayed onto the vehicle body during a car wash or the like, it is difficult to prevent water from entering the roof opening between the hood a and the vehicle body. The present invention was devised under the above circumstances, and is a hood that can reliably prevent rainwater from entering the vehicle interior through the roof opening in an automobile equipped with a hood that covers the roof opening. Its purpose is to provide a sealing structure between the roof opening and the roof opening.

[Means to solve the problem]

In order to solve the above problems, the present invention takes the following technical measures. That is, the present invention provides a sealing structure between the hood and the roof opening in an automobile in which the roof is provided with an opening and a hood that covers the roof opening, wherein the hem of the hood is connected to the roof opening. A sealing member is provided at a portion of the vehicle body closer to the roof opening than a portion of the vehicle body to which the hood is fixed, and a hood shape with rigidity is provided at a portion of the hood that abuts the sealing member. A girder-shaped second seal body that contacts the vehicle body is provided between the hem portion and the contact portion of the hood, and the hood that is attached to the hem portion is provided with a second seal body that is in contact with the vehicle body. It is characterized by being curved convexly at the part supported by.

[Action and effect]

The seal structure of the invention fixes the hem of the hood to the vehicle body surrounding the roof opening, provides a sealing member in a region of the vehicle body closer to the roof opening than the region where the hem of the hood is secured, and furthermore, A hood-shaped member having rigidity is provided at the abutting portion for the sealing member in the hood, and a girder-shaped second sealing body that abuts against the vehicle body is provided between the bottom portion and the abutting portion of the hood, and The top, which is attached to the hem, is curved in a convex manner at a portion supported by the second seal body. Therefore, the top is securely fixed to the vehicle body at a portion of the top that is outside the contact portion of the top against the sealing member, so that it is possible to prevent the top from flapping in the vicinity of the contact portion when the vehicle is traveling. That is, the hood and the seal member can always have a substantially constant positional relationship. Further, due to the rigidity of the hood shaping member, it is possible to provide a flexible hood with appropriate rigidity at the portion that contacts the sealing member. Therefore, when the hood presses the sealing member, it is possible to compensate for the lack of sealing pressure due to the flexibility of the hood, and to obtain uniform and sufficient sealing pressure along the sealing member. Furthermore, in addition to the sealing structure created by the contact between the sealing member on the vehicle body side and the top shaping member of the top, a second sealing structure created by contacting the girder-shaped second sealing body and the vehicle body is provided. As a result, the seal structure becomes a double structure, which dramatically improves sealing performance. In order to ensure that the second seal body contacts the vehicle body in the hood-attached state, the present invention further includes a portion supported by the second seal body in the hood-attached state to be curved in a convex manner. That is,
Due to the tension acting on the top in the fixed state, the girder-shaped second seal body comes into close contact with the vehicle body. Therefore, by applying sufficient tension to the top, the abutment between the top shaping member, which is the first seal structure, and the sealing member on the vehicle body side becomes more reliable. In other words, the sealing pressure between the weather strip, which is a sealing member, and the hood shaping member increases accordingly, and as a result, the sealing performance between the hood shaping member and the sealing member is further improved. It will be done. Furthermore, the second seal body causes the vicinity of the hem of the top to bulge neatly into a peak shape, thereby improving the appearance of the vehicle body when the top is attached. As described above, in the present invention, a constant positional relationship is maintained between the sealing member and the part of the hood that touches the sealing member, and the hood is attached to the sealing member with uniform and sufficient sealing pressure along the sealing member. It can be pressed into contact with the Therefore, the sealing performance between the hood and the roof opening can be dramatically improved, thereby reliably preventing rainwater from entering the vehicle interior. In addition, since the hood is flexible, it is not easy to create corners etc. neatly without using a support such as hood ribs, but in the present invention, the hood shaping member allows Since it is possible to provide appropriate rigidity to desired parts, it is easy to shape the top when it is put on.
