Abstract

(57) [Summary] [Purpose] A lightweight flat panel panel for automobiles is obtained which is made of a single flat parison and is made of a resin that is hard and soft on the inner and outer surfaces of the outer panel of the vehicle. [Constitution] It consists of a single flat parison and its outer surface 10
Is molded with a hard synthetic resin, and the inner surface 11 is blow molded with a soft synthetic resin. As a result, a lightweight automobile outer panel A according to the purpose of use is obtained, and the outer surface 10 is not damaged or dented even if a certain amount of external force is applied, and the inner surface 11 is temporarily contacted by the user. However, it can give a soft feeling.

[Detailed description of the device]

[0001]

[Industrial applications]

 TECHNICAL FIELD The present invention relates to a blow molded automobile outer panel.

[0002]

[Prior Art]

 2. Description of the Related Art Conventionally, automobile outer panel panels are often made of metal in order to have strength.

[0003]

[Problems to be solved by the device]

 However, as automobiles have become lighter and faster in recent years, the use of synthetic resins such as frames is gradually progressing. An object of this invention is to provide the market with a lightweight outer panel panel for an automobile, which meets the above-mentioned demands and which has a resin on its inner and outer surfaces which is hard and soft depending on the purpose of use.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention is characterized in that it is composed of a single flat parison, the outer surface of an automobile outer panel is molded with a hard synthetic resin, and the inner surface is blow molded with a soft synthetic resin. .. In order to solve the above-mentioned problems, it is preferable that the vehicle outer panel of the present invention is a ceiling panel, the outer surface of which is located outside the vehicle body and the inner surface of which is located inside the vehicle body. In order to solve the above-mentioned problems, the automobile flat panel panel of the present invention is a door panel, the outer surface of which is located outside the vehicle body and the inner surface of which is located inside the vehicle body. There is also.

[0005]

[Action]

 In the invention according to the first aspect of the present invention configured as above, the outer panel is a hollow molded product and is attached to a corresponding vehicle mounting location. According to the second aspect of the invention, since the outer surface of the ceiling panel is made of a hard synthetic resin, it has some strength against external force from the outside, and its inner surface is made of a soft synthetic resin. Therefore, even if the occupant comes into contact with the occupant, the occupant does not feel uncomfortable and exhibits elasticity. According to the third aspect of the invention, the outer surface of the door panel becomes hard, and even if a small external force is applied, it is not damaged and returns to its original shape by its elasticity due to its hollow. Also, since the inner surface of the door panel is soft, it will not be damaged even if it hits the elbow, giving a soft feel.

[0006]

【Example】

 A typical embodiment of the invention described in claims 1 and 2 will be described. Example 1 In FIG. 1, A is an automobile ceiling panel, and this ceiling panel A is made of a single flat parison, and an outer surface 10 located outside the vehicle body is made of a hard synthetic resin (for example, hard PP). And the inner surface 11 located inside the vehicle body is blow molded with a soft synthetic resin (for example, soft PP). This invention is the same even if the hollow portion 12 of the ceiling panel A is filled with a heat insulating material.

Embodiment 2 This embodiment is a representative embodiment of the invention described in claims 1 and 3, and the difference from the embodiment 1 is that the whole panel is an automobile door panel B, and The outer surface 10a is located outside the vehicle body, and the inner surface 10b faces the inside of the vehicle body. Others have the same structure as in Example 1 (see FIG. 2).

[0008]

[Effect of the device]

 According to the invention of claim 1, which is constructed and acts as described above, the outer surface is not damaged or dented even if a certain external force is applied, and the inner surface has a soft feeling even if the user temporarily contacts it. Can be given. According to the second aspect of the invention, since the outer surface of the top panel is made of hard synthetic resin, it can exhibit some strength against external force from the outside, and its inner surface is made of soft synthetic resin. Therefore, even if the occupant comes into contact with the occupant, the occupant does not feel uncomfortable and can exhibit elasticity. According to the third aspect of the present invention, the outer surface of the door panel becomes hard, and even if a small external force is applied, it is not damaged, and the hollow shape allows it to return to its original shape. Also, since the inner surface of the door panel is soft, it will not be damaged even if it is hit by elbows, giving a soft feel.

Effect of Embodiments The outer surface of the panel is made of hard P. P. The outer surface is not scratched by pedestrians while they are stopped, baggage when getting on or off, and collisions such as pebbles while walking. The inner surface is soft P. P. Therefore, it has a soft feeling, and since it has elasticity, it does not feel uncomfortable and exhibits a cushioning effect.
