Description

  The present invention relates to a vehicle panel that is mounted in an opening of a vehicle.

  Conventionally, various types of vehicle panels have been proposed. For example, in the vehicle panel disclosed in Patent Literature 1, synthetic resin panels arranged in a laminated form for improving sound insulation and heat insulation are connected between the panels via ribs. In this case, since the linear expansion coefficient of the synthetic resin is large, when the synthetic resin panel contracts, there is a problem that a gap is generated between the edge of the synthetic resin panel and the opening of the vehicle to which the panel is mounted.

  Therefore, the vehicle panel of Patent Document 2 is composed of a glass panel and a synthetic resin panel arranged in a laminated manner, and a rib integrally formed with the synthetic resin panel is fixed to the glass panel. Being connected. In this case, since glass has a smaller linear expansion coefficient than that of synthetic resin, it solves the problem that a gap is generated between the glass panel and the opening of the vehicle.

JP 2000-142119 A JP 2010-006357 A

  However, since the linear expansion coefficient of the synthetic resin panel is larger than that of the glass panel in Patent Document 2, the amount of expansion and contraction of the synthetic resin panel is larger than that of the glass panel with respect to changes in environmental temperature. Become. As a result, there is a difference in the amount of expansion / contraction between the two panels, and a repeated stress acts on the fixing portion of the rib connecting the panels, which may cause fixing failure or bending of the panel.

  The present invention has been made in view of the above-described problems, and reduces stress acting on a fixing portion that connects panels having different linear expansion coefficients arranged in a laminated manner, thereby solving poor fixing or bending of the panel. An object is to provide a vehicle panel.

  A first problem-solving means of the present invention is a vehicle panel that is mounted in an opening of a vehicle, and is provided on the vehicle inner side than the first panel, and is different from the first panel. A second panel having a linear expansion coefficient; and a fixing portion that fixes a peripheral edge of the first panel and a peripheral edge of the second panel, wherein the second panel has a center of the second panel rather than the fixing portion. It is the structure which has the expansion-contraction absorption part which is located in the side and absorbs expansion-contraction to the direction along the said 2nd panel.

  The second problem-solving means of the present invention is a configuration in which the expansion / contraction absorbing portion has a protruding shape protruding in a direction different from expansion / contraction in a direction along the second panel.

  Here, the “periphery” does not mean only the end portion, but also includes a portion located on the center side to some extent from the end portion of the second panel.

  The third problem-solving means of the present invention has a configuration in which the protruding shape protrudes in a direction different from the expansion and contraction in the direction along the second panel.

  In the vehicle panel of the present invention, the first panel and the second panel are arranged in a stacked manner, and the expansion / contraction absorption part of the second panel absorbs the expansion and contraction of the second panel in the direction along the second panel. While maintaining heat insulation and sound insulation, the stress acting on the fixing portion can be reduced, and the problem of fixing failure or panel deflection can be solved.

  Moreover, since the expansion / contraction absorption part which is the protrusion shape which protrudes in a direction different from the direction along the second panel is formed integrally with the second panel, the expansion / contraction absorption part is formed of a member or material different from the second panel. This can prevent an increase in manufacturing cost.

  In addition, since the protrusion shape is configured to protrude in a direction different from the direction along the second panel, the expansion / absorption part absorbs the expansion / contraction of the second panel compared to the case where the expansion / absorption part has one protrusion shape. The amount can be made larger. In addition, since the decrease in the amount of absorption of the expansion / contraction absorption part by reducing the height of the protrusion of the expansion / contraction absorption part can be compensated by a plurality of protrusions, the height of the protrusion of the expansion / contraction absorption part can be reduced. .

  The glass panel 11 and the resin panel 21 expand and contract due to temperature changes. The expansion / contraction absorption part 22 functions to absorb expansion / contraction of the resin panel 21 due to this thermal expansion / contraction. When the resin panel 21 expands in the front-rear direction, the base end part 25a and the base end part 25b of the stretchable absorption part 22 move in a direction approaching each other, and the length L13 of the upper protruding part 23 and the length of the lower protruding part 24 The length L12 is shortened, and the entire length L11 of the stretchable absorbing portion 22 is shortened. Further, in the upper protruding portion 23, when the length L13 of the upper protruding portion 23 is shortened, the top portion 26a of the upper protruding portion 23 extends upward, and the height H of the upper protruding portion 23 is increased. Further, in the lower protruding portion 24, when the length L12 of the lower protruding portion 24 is shortened, the top portion 26b of the lower protruding portion 24 extends downward, and the height H of the lower protruding portion 24 is increased. When the resin panel 21 contracts in the front-rear direction, the base end part 25a and the base end part 25b of the stretchable absorption part 22 move in a direction away from each other, and the length L13 of the upper projecting part 23 and the length of the lower projecting part 24 The length L12 becomes longer, and the entire length L11 of the stretchable absorbing portion 22 becomes longer. Further, in the upper protruding portion 23, the top portion 26a of the upper protruding portion 23 is contracted downward by increasing the length L13 of the upper protruding portion 23, and the height H of the upper protruding portion 23 is decreased. Further, in the lower protruding portion 24, the length L12 of the lower protruding portion 24 is increased, whereby the top portion 26b of the lower protruding portion 24 is contracted upward, and the height H of the lower protruding portion 24 is decreased. By the operation of the expansion / contraction absorption part 22, the expansion / contraction absorption part 22 acts as a spring and absorbs expansion / contraction of the resin panel 21.

(1) In the vehicle panel 10 of the present invention, the expansion and contraction absorbing portion 22 of the resin panel 21 absorbs the expansion and contraction of the resin panel 21, so that the stress acting on the fixing portion 30 can be reduced, and the problem of fixing failure Can be solved. Moreover, even when the glass panel 11 and the resin panel 21 are fixed by integral molding, the problem that the glass panel 11 or the resin panel 21 is bent due to expansion and contraction can be solved. In addition, since the glass panel 11 and the resin panel 21 are arrange | positioned in the laminated form, the panel 10 for vehicles can also hold | maintain heat insulation and sound insulation.

The upper protrusion 43a is in a state where the height of the upper protrusion 43 is the highest, and the height H1 is the height in that state. Since the height H2 between the glass panel lower surface 12 and the bottom 41a of the rib 41 is higher than the height H1 of the upper protrusion 43a, the top 46 does not contact the glass panel lower surface 12 of the glass panel 11 due to the expansion and contraction of the resin panel 21. It has a structure. Further, when the resin panel 21 contracts in the front-rear direction, the base end part 45a and the base end part 45b of the stretchable absorption part 42 move away from each other, and the length L21 of the upper projecting part 43 becomes longer. As the length L21 of the upper protrusion 43 increases, the top 46 of the upper protrusion 43 contracts downward, and the height H of the upper protrusion 43 decreases. By the operation of the expansion / contraction absorption part 42, the expansion / contraction absorption part 42 functions as a spring and absorbs expansion / contraction of the resin panel 21.

  As described in detail above, according to the second embodiment, the following effects can be obtained in addition to the effects (1) and (2) in the first embodiment.

(1) Since the rib 41 is formed in the resin panel 21, the bending strength of the vehicle panel 10 can be reinforced. In addition, since the height H2 between the glass panel lower surface 12 and the bottom 41a of the rib 41 is higher than the height H1 of the upper protrusion 43a, the expansion / contraction absorbing portion 42 provided integrally with the rib 41 by the expansion / contraction of the resin panel 21. It is possible to prevent contact between the top 46 of the upper protrusion 43 and the glass panel lower surface 12 of the glass panel 11.
