Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for attaching a trunk lid hinge to a vehicle so that the trunk lid can be opened and closed.

2. Description of the Related Art Conventional trunk lid hinge mounting structures include, for example, those shown in FIGS. 1 and 2. Reference numeral 1 in the figure indicates hinge arms, which are arranged in pairs at symmetrical positions in the vehicle width direction (arrow X direction in the figure), and one end of which is rotatably supported by hinge brackets 6 attached to both ends of the rear parcel 2 in the vehicle direction. At the same time, the other end is fixed to a trunk lid reinforcement 5 provided on the back surface of the trunk lid 4 with bolts 6. This hinge arm 1tj, trunk lid 4
The hinge bracket 6 and the trunk lid 4 are rotated upward to a predetermined position to open the trunk compartment 7.
It has a curved beam shape with an appropriate curvature so as not to come into contact with the rear waist panel 9 that supports the rear window glass 8 provided at the intersection, and the entire body projects into the trunk room 7.

10 is a torsion bar, and two torsion bars are provided across the width direction of the vehicle, and one end of each is engaged and fixed to the hinge bracket 6.
The other end is engaged with the hinge arm 1 so that it can be twisted as the hinge arm 1 rotates. As shown in the figure, the torsion bar 10 extends in the vehicle width direction inside the trunk room 7 with its mounting position shifted downward from the hinge center 11 of the hinge arm 1, and is used to rotate the trunk lid 4 upward. It generates a moment.

Reference numeral 12 in the figure is a rear seat, and a place 13 standing between the cell 2 and the floor panel (not shown) in the lantern is arranged on the rear side.

However, in such a conventional trunk lid hinge mounting structure, the hinge arm 1 straddles the rear waist panel 9 and connects the rear parcel 2 and the trunk lid 4.
Since both ends of the hinge arm 1 are attached to the hinge arm, the size and curvature of the hinge arm 1 become large, which causes the hinge arm 1 to protrude into the trunk compartment 7, making it difficult to use the space in the luggage compartment 7 effectively. There were other problems, such as the need to devise a new loading method. Furthermore, the torsion bar 10 also protrudes into the trunk compartment 7, which considerably obstructs the vehicle 1- when loading something such as a golf bag, for example.

This invention focused on these conventional problems12, and made the hinge arm small to prevent it from protruding into the trunk room. A space is formed in front of the drip groove on the upper edge of the trunk lid opening by providing a hinge bracket on the bottom surface of the rear waist panel and attaching the hinge arm, and by placing a torsion bar at a position corresponding to the hinge center of the hinge arm. This is an effective use of.

The present invention will be explained below based on the drawings.

Similarly, in the following explanation, common parts in the conventional art are given common reference numerals and redundant explanations will be omitted.

FIGS. 3 and 4 are diagrams showing an embodiment of the present invention. To explain its structure, reference numeral 20 in the figure is a hinge bracket, which has a substantially housing shape that combines a first reinforcing member 21 and a second reinforcing member 22, and has a hinge arm 26 with reinforcing members 21 and 22 on both sleeves. It is clamped and rotatably supported at the hinge center 25. This hinge bracket 20 is manufactured by suitable means such as welding and is fitted into the space formed by the rear waist panel 2 and the rear waist panel 9 in front of the upper edge drip groove 91 of the trunk lid opening. A pair at symmetrical positions in the vehicle width direction, both of the above ξ
It is fixedly installed so as to connect the panels 2 and 9, and serves as reinforcement for the rear waist panel 9 to improve splitting properties.

Hinge arm 23H, rear waist panel 9 on the trunk lid 4 side from the center 25 and the first. Second
It is formed into a curved beam shape 17 with an appropriate curvature so as not to come into contact with the both sleeve reinforcing members 21 and 22 during rotation, and is smaller and has a smaller curvature than the conventional one.

Two torsion bars 26 are arranged facing each other across the vehicle width direction at a position corresponding to the hinge center 25 of the hinge arm 26, and both ends thereof are bent into a hook shape, and a notch of the hinge arm 26 is inserted between one end. 27, and the other end @ is locked to a hook portion 28 provided on the first reinforcing member 21 of the hinge bracket 20, so that it does not extend into the trunk room 7. In the illustrated example, Toshi Yonper
26 is substantially aligned with the hinge center 25, but the position may be slightly shifted.

Now rotate the trunk lid 4 and open the trunk compartment 7.
We will explain the opening and closing conditions.

When the trunk lid 4 is rotated, the hinges 1 and 26
As the trunk lid 4 rotates, it rotates while drawing a small rotation locus around the hinge center 25. Further, the torsion bar 26 is simply taken or twisted back at the hinge center 25 using the end of the first reinforcing member 21 that is engaged with the hook portion 28 as a fulcrum. Although the torsion bar 26 and the weight of the rear windshield 8 are always applied to the rear waist panel 9, the rear waist panel 9 is connected to the rear parcel 2 by a hinge bracket 20 that also serves as a reinforcement, improving its rigidity. and will not bend.

As explained above, according to the present invention, the hinge arm connected to the trunk lid is rotatably attached to the hinge bracket provided on the lower surface of the rear waist panel, and one end is engaged with the hinge arm. Since the torsion bar is supported across the vehicle width direction at a position corresponding to the hinge center of the hinge arm, the hinge arm only comes into contact with the hinge arm and the part of the hinge bracket that is located from the hinge center to the trunk lid side. Since the distance from the hinge center to the edge of the opening is shortened, it can be made smaller and have a smaller curvature than before, so the overhang into the trunk is small, and the inside of the trunk can be further expanded. The effect is that it can be used effectively.

Furthermore, since the torsion bar does not protrude into the trunk, the hinge arm can be made smaller and have a smaller curvature, and the trunk can be used more effectively.

Furthermore, by connecting the rear parcel and rear waist panel with a hinge bracket as in the above embodiment, the space below the rear waist panel can be made into a closed cross-section structure, which improves the rigidity of the rear waist panel and prevents twisting of the torsion bar. It is also possible to prevent the rear waist panel and the rear parcel from bending even when a reaction force or the weight of the rear window glass is applied without increasing the number of parts.

Claims (1)

[Claims] A hinge bracket is provided in the lower space of the rear waist nominal in front of the upper edge drip groove of the trunk lid opening, and a hinge arm connected to the trunk lid is rotatably attached to the hinge bracket, and the hinge center of the hinge arm is located at a corresponding position. The installation structure of the trunk lid hinge is formed by engaging the hinge arm with one end of a torsion bar that is sharpened in the vehicle width direction.
