Description

  The present invention relates to a trunk lid device capable of holding a trunk lid in a fully open position.

  2. Description of the Related Art Conventionally, there is known a vehicle provided with a boot room at the rear of a vehicle body and having an openable / closable boot lid at the opening of the boot room. A pair of hinge arms are integrally provided on the inner surface of the boot lid, and one end of the hinge arm is rotatably supported on the front edge side of the opening of the boot. The hinge arm is provided with a torsion bar that biases the hinge arm in a direction to turn the trunk lid upward, and the operation of the torsion bar assists the opening and closing of the trunk lid and holds the fully open position.

  Here, when the biasing force by the torsion bar is strong, the trunk lid is held firmly in the fully open position, but when the key is opened to open the boot lid, the boot lid lifts up at a higher position. , There is a problem that it gives a sense of harm to the operator. Conversely, when the biasing force by the torsion bar is weak, the pop-up position is lowered and there is no sense of harm to the operator, but the holding power of the trunk lid at the fully open position is weak and the vehicle is inclined or the wind is strong. For example, there is a problem that the trunk lid closes naturally.

  In order to solve the above-mentioned problems, there is known a technique in which a locking means for locking the hinge arm pivoted together with the trunk lid by an elastic force is provided on the vehicle body side (see, for example, Patent Document 1) ).

As shown in FIGS. 1 to 3, a trunk lid 2 is provided so as to be openable and closable at the opening of a trunk R provided at the rear of the vehicle body 1. One end of each of a pair of hinge arms 3 is integrally attached to the inner surface of the trunk lid 2, and the other end of each hinge arm 3 is vertically pivotable by a support bracket 4 provided on the vehicle body 1. It is supported. Further, a torsion bar 5 as an urging means is attached to the hinge arm 3, and an urging force in a direction to turn the trunk lid 2 upward is applied to the hinge arm 3 by the torsion bar 5. There is. By the function of the torsion bar 5, the opening / closing assistance and the full open position holding of the trunk lid 2 are performed.

  In the trunk lid device 10 of the present embodiment, holding means 9 is provided which engages the hinge arm 3 with the vehicle body 1 at the fully open position of the trunk lid 2 and holds the trunk lid 2 in the fully open position. The holding means 9 has an elastic holding member 6 and an engagement member 7. The elastic holding member 6 is disposed at a position facing the hinge arm 3 at the fully open position of the trunk lid 2. The elastic holding member 6 is formed of an elastic non-metallic material such as rubber or resin having an impact absorbing function, and provided so as to elastically contact the hinge arm 3 side at the fully open position of the trunk lid 2. ing. Specifically, the elastic holding member 6 is formed of a material such as natural rubber, chloroprene rubber, urethane resin or the like. As shown in FIGS. 4 and 5, the elastic holding member 6 has a concave hole 6a opposite to the hinge arm 3 and opened at a portion (surface) elastically contacting with the hinge arm 3 side. . An engaging member 7 described later is engageable with the hole 6a. At the inner peripheral portion of the hole 6a, a bulging portion 6c which bulges out to the inside of the hole 6a is formed. In the present embodiment, the bulging portion 6c is provided in a pair so as to face the peripheral edge of the opening of the hole 6a in the rotation axis direction (vehicle width direction) of the trunk lid 2 (see FIG. 5). The elastic holding member 6 integrally has a mounting portion 6b on the side opposite to the opening of the hole 6a, and the elastic holding member 6 is fixed to the pedestal portion 8 of the vehicle body 1 by the mounting portion 6b.
