Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to the body structure of a vehicle such as an automobile, and specifically relates to the structure of a molded ceiling for a vehicle having an opening for a sunroof.

[Conventional technology]

Conventionally, molded ceilings using heat-cured phenol-impregnated recycled cotton felt attached to the roof panels of automobiles with sunroofs have been difficult to assemble into actual vehicles due to lack of strength and rigidity at the front and rear ends of the gently curved openings. Surface deformations such as warping and corrugations are likely to occur in the subsequent molded ceiling product. Therefore, the following preventive measures have been taken so far.

1. Further harden the base material by increasing the amount of thermosetting resin.

2. Increase the basis weight of fragile parts by material distribution of the base material to provide rigidity.

However, in case 1, curing time is required by the amount of resin increased, which increases the number of man-hours, lowers labor productivity, and inevitably increases resin material costs. In addition, in case 2, it is possible to increase the rigidity of the fragile part by changing the material distribution of the base material, but in order to achieve the specified product thickness as a sheet cover, the basis weight of the base material must be adjusted. There are limits, and a sufficient increase in rigidity cannot be expected.

A specific example of a conventional molded ceiling structure is shown in the cross-sectional view of FIG. 8, but some cars have an additional fiber material attached to the inside to replenish the molded ceiling, which can be attached freely. . However, this also has the disadvantage that it takes time for the operator to make installation adjustments. Further, since the molded ceiling structure of the front roof panel is provided, the weight of the roof panel increases due to its structure, and the tension force in the panel is required. Furthermore, it is attached to the inside of the roof panel, etc., to properly apply tension to the panel, and is attached to the interior near the end hugged by the attached skin material, and also to tighten the entire periphery of the skin material. There was a problem in that it required a lot of effort since it had to be folded.

[Problem that the invention attempts to solve]

The present invention was devised in view of the above-mentioned problems with molded ceilings for automobiles and other vehicles equipped with an opening for a sunroof. It is an object of the present invention to provide a molded ceiling structure for a vehicle such as an automobile, which can be efficiently mounted on a sunroof, has high rigidity even at the front and rear ends of an opening for a sunroof, and does not cause deformation of the surface shape.

[Means for solving problems]

The molded ceiling structure for automobiles and other vehicles of the present invention is used in molded ceilings for automobiles and other vehicles in which a skin material and a base material are integrated and molded as a single piece. The gist is that a reinforcing structure consisting of a net-like core material that can be elastically deformed and a patch material that wraps the core material is applied to the base material at the corresponding position, and the reinforcing structure is held by a skin material.

[Effect]

In this invention, a reinforcing structure consisting of a net-like core material that can be elastically deformed and a patch material that wraps this core material is applied to the easily deformable end part of the molded ceiling that corresponds to the opening of the vehicle roof panel, and the reinforcement structure is Since it is held in place by the material, the front and rear ends of the opening for the sunroof have high rigidity and no deformation of the surface shape occurs.

[Mode of implementation]

According to a first embodiment of the present invention, there is provided a ceiling structure for a vehicle such as an automobile, in which a mesh core material is made of fine diameter glass fibers incorporated in an aluminum skin material in a lattice pattern. According to an embodiment, the reinforcing structure can have a very small thickness, so that it has the advantage that it can be molded simultaneously with the hot pressing of the molded ceiling.

According to a second embodiment of the present invention, there is provided a ceiling structure for a vehicle such as an automobile, in which the size of the reinforcing structure is a rectangle slightly larger than the width of the roof panel opening. According to this embodiment, there is an advantage that the entire end portion, which is most prone to deformation, can be reinforced.

[Effect of idea]

As explained above, the present invention increases rigidity by hugging the reinforcing structure at the front and rear ends of the opening for the sunroof, so when the molded ceiling is assembled to the roof panel, the surface shape deformation does not occur. In other words, because it is a molded product with much higher rigidity than conventional products, it can be bent freely even when attached to the inside of the front roof panel without bending the edges of the product. , manual correction or rebending is possible. Therefore, there is an effect that the operator does not have to take any time to adjust the installation. In addition, since the molded ceiling of this invention is molded all at the same time using a hot press, unnecessary man-hours are eliminated, and since the aluminum foil is extremely thin, it is compatible with the hot press machines and hot press molds of current manufacturing equipment. However, under the manufacturing conditions already set,
A molded ceiling molding of a specified thickness that is necessary and sufficient is completed.
