Embodiment Construction
[0032] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0033] Figure 1 ~ Figure 4 The tailgate 1 according to the first embodiment of the present invention is shown. In each figure, the rear door 1 is a hatchback type rear door that can be opened and closed at the rear opening of the vehicle body, and a window opening 10 is provided on the upper part, and the outer panels are made of thin-walled resin molded products. 2 and the inner panel 3 are formed into a hollow structure (Japanese: monaka structure) ( clamshell construction).
[0034] The rear door 1 (inner panel 3 ) is composed of an upper end portion 11 forming the upper side of the window opening 10 , pillar portions 12 , 12 forming the left and right sides of the window opening 10 , and a main body portion 13 below the window opening 10 . Two parts on the left and right of the upper end 11 are provided with mounting parts for the hinge 5, and the rear...

The present invention provides a resin tailgate that can ensure rigidity and impact resistance without relying on metal parts, and is advantageous for weight reduction and cost reduction. In the resin rear tailgate (1), the outer panel (2) and the inner panel (3) are joined together by the peripheral portion, and the upper end portion (11) is connected to the upper edge of the rear opening of the vehicle body through the hinge (5), and can By engaging and disengaging the lock body (6) installed on the lower end portion (14) with respect to the latch fixed on the lower edge of the rear opening of the vehicle body, a structure connecting the upper end portion (11) and the main body portion (13) is arranged in the interior space ), wherein a pair of ribs (33) protrude from the inner surface of the inner panel (3) at any one of the left and right support portions (12) forming the window opening (10). ) is formed between them, and reinforcing long fibers (33f) are insert-molded in the cross section of the inner panel (3) along the passage.
Description
technical field [0001] The invention relates to a rear tailgate arranged at the rear opening of a vehicle body, in particular to a hatchback type resin rear tailgate. Background technique [0002] In recent years, the resinization of the vehicle body has been promoted for the purpose of weight reduction, and various issues related to the resinization of the rear tailgate installed in the rear opening of the automobile body have been studied. As a problem when resinizing the rear tailgate, since the rigidity is lower than that of the metal plate, and the impact resistance is also weak, when an impact load acts from the rear of the vehicle due to a rear impact, etc., the panel may be damaged. risk of fragmentation. [0003] As a countermeasure for reinforcement and rear impact, Patent Document 1 discloses that a metal plate reinforcement is extended from the hinge part through the window frame to below the waistline, and the hinge part at the upper end and the lock body part ...
