Abstract

(57) [Summary] [Purpose] In a rear spoiler in which the upper part and the lower part made of a plastic molded body are adhesively fixed to each other at their peripheral edges and a hollow part is provided, the upper part surface does not have sink marks and the appearance quality is high. (EN) Provided is a rear spoiler that is improved and does not require the conventional shape modification. [Structure] A cushioning material 5 made of foamed rubber or the like is attached to a portion of the inner surface of the upper portion 1 that abuts the rib 3 of the lower portion 2 with a double-sided adhesive tape 6 or the like, and the peripheral portions of the upper portion 1 and the lower portion 2 are made of an adhesive. Adhere and fix.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a rear spoiler mounted on a rear portion of a trunk lid or a roof of a passenger vehicle in order to ensure stability during traveling.

[0002]

[Prior Art]

 Rear spoilers often have a wing shape in cross section and have a hollow structure to reduce weight.The material used for the rear spoiler is glass fiber as a reinforcing material from the viewpoint of formability, strength and rigidity. Reinforced plastics (FRP) are generally used, and those made of sheet molding compound (SMC), which excels in mass productivity, are often used.

In order to make the rear spoiler have a hollow structure, as shown in FIG. 2 which is a sectional view taken along the line AA of FIG. 1, it is made up of two parts, an upper part 1 and a lower part 2 which are plastic molded bodies such as FRP. In this structure, each peripheral edge is bonded and fixed through the adhesive 4 and integrated. By the way, the above rear spoiler must withstand a load (about 50 kg) from above, and in order to counter this load, conventionally, as shown in FIGS. 2 and 4, as shown in FIGS. When the upper portion 1 and the lower portion 2 are bonded together, the abutting portion between the tip of the rib 3 and the inner surface of the upper portion 1 is also bonded at the same time to improve the strength. I am trying to improve.

[0004]

[Problems to be solved by the device]

 In the structure described in the prior art, since the contact portion between the rib 3 tip of the lower portion 2 and the inner surface of the upper portion 1 is bonded with the adhesive 4, the inner surface of the upper portion 1 and the tip of the rib 3 are bonded. When the intervening adhesive 4 cures, it contracts, the adhesive portion of the upper portion 1 is pulled, and the phenomenon that the surface of the upper portion is pulled in a concave shape (commonly called a sink mark) occurs. Since this sink mark is a defect in the appearance of the upper part 1 itself, there is a problem that the commercial value of the rear spoiler is impaired.

In addition, in order to make the sink marks less noticeable, it is necessary to apply putty to this portion, and after the putty is cured, the putty must be rubbed to correct the shape, which is a troublesome work. I had.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a rear spoiler with improved appearance quality without causing sink marks on the upper surface. It is intended to provide the structure of.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the structure of the rear spoiler in the present invention is the structure of the rear spoiler in which the upper part and the lower part, which are separately formed plastic moldings, are attached and fixed at their peripheral edges to provide a hollow part. A cushioning material is interposed between a rib projecting from the inner surface of the lower portion and an inner surface of the upper portion facing the rib.

The cushioning material may be attached in advance on the inner surface of the upper portion where it abuts against the rib, or the upper portion and the lower portion may be attached at the peripheral edge so as to intervene without being attached. The material shall not be glued. The thickness of the cushioning material and the height of the ribs are set so that the ribs are almost in contact with the cushioning material when the upper portion and the lower portion are bonded and assembled.

[0009]

[Action]

 Since no adhesive is used between the inner surface of the upper part and the ribs, the sink marks due to the hardening and shrinking of the adhesive in the past are eliminated.

[0010]

Embodiment An embodiment of the present invention will be described below with reference to FIG. The upper portion 1 and the lower portion 2 are separately formed by FMC SMC molding or the like, and a rib 3 is formed on the inner surface of the lower portion 2 so as to project. In FIG. 3 (a), a flexible cushioning material 5 made of foamed rubber or plastic foam is interposed between the inner surface of the upper portion 1 and the tips of the ribs 3 of the lower portion 2 so as to be sandwiched. In this example, the peripheral edges of the upper portion 1 and the lower portion 2 are bonded and fixed with an adhesive. In FIG. 3 (b), the above-mentioned cushioning material 5 is preliminarily attached to the inner surface of the upper portion 1 by the double-sided adhesive tape 6, and the peripheral portions of the upper portion 1 and the lower portion 2 are adhered and fixed by an adhesive so that they are interposed. It is an example.

[0011]

[Effect of the device]

 As described above, the rear spoiler according to the present invention has a structure in which the cushioning material is interposed between the rib projectingly provided on the inner surface of the lower portion and the inner surface of the upper portion facing the rib, and therefore, the surface of the upper portion has a sink mark. There is an effect that the appearance quality can be improved without any occurrence and the conventional work such as shape correction becomes unnecessary.
