が変形するという欠点がある。 Recently, due to the desire to reduce the weight of vehicle bodies, attempts have been made to use lightweight composite materials or aluminum materials for the outer panels of lids such as bonnets and trunks.
As shown in, for example, Japanese Utility Model Application No. 53-129015, the structure of the lid is such that a stiffener having a substantially channel-shaped cross section is formed on the inner panel, and the flange portion of the stiffener is bonded to the outer panel using an adhesive. With this structure, when the adhesive is cured in a drying oven, it is usually exposed to high temperatures of around 180℃, but if the outer panel is made of a lightweight composite material or aluminum material and the inner panel is made of steel material, it is possible to There is a drawback that the outer panel, which is weaker in strength than the stay material (inner panel), deforms during shrinkage, resulting in poor appearance.
Furthermore, since the inner panel and the outer panel have different coefficients of thermal expansion, there is a drawback that the outer panel deforms due to changes in outside temperature.

In other words, this invention consists of an outer panel made of a lightweight composite material or aluminum material and an inner panel made of a steel material.The inner panel has a section that serves as a stiffener and is formed into a substantially channel-shaped cross section, and an unnecessary portion is formed. is punched out, and joints are formed that extend integrally from the stiffener at predetermined intervals at appropriate locations along the length of the stiffener and protrude in the width direction of the stiffener, and are bonded between the joints and the outer panel. This is achieved through the intervention of an agent.

されて接合がなされている。 Embodiments of this invention will be described below with reference to the drawings. In Figures 1 to 3, a lid 1 consists of an inner panel 2 made of stainless steel and an outer panel 3 made of a light composite material or aluminum. A stiffener 5 having a shape is formed and joins the inner panel 2 and the outer panel 3 by hemming the peripheral edge of the outer panel 3. In the illustrated example, four triangular punched parts 4 are formed, but the shape, number, arrangement, etc. can be changed in various ways. A flange portion 6 is integrally formed on the side portion of the stiffener 5 along its longitudinal direction, and joint portions 7 are formed integrally with the stiffener 5 at predetermined intervals to form a flange portion. This joint part 7 is separated from the flange part 6 by notches 9 on both sides, a longitudinal bead 70 is formed in the center, and a mastic sealer, which is an adhesive, is applied between the joint part 7 and the outer panel 3. 8 is interposed to make the connection.

Further, a longitudinal slot 72 is formed between the joint portion 71 and the stiffener 5. The shape of the joint portion 71 does not have to be T-shaped, and may simply have a shape corresponding to the planar shape of the mastic sealer 8.

りアウタパネル３が変形することは防止される。 In any of the above configurations, since the joint part is formed to protrude from the stiffener 5, the joint part absorbs the shrinkage stress and the difference in thermal expansion when the adhesive hardens. This is done by a bead 70 in the width direction.
Alternatively, this is achieved by relative movement between the stiffener 5 and the stiffener 5 through the slot 72. Therefore, even if the outer panel 3 is weaker in strength than the inner panel 2, the outer panel 3 is prevented from being deformed due to the joint moving together with the outer panel 3.

This prevents deformation of the outer panel.
