  However, in the case of the above Patent Documents 1 and 2, there is a problem that, depending on the loading position of the load, when the trunk lid is closed, the hinge arm interferes with the load during the rotation. Therefore, when the two interfere with each other, it is necessary to open the trunk lid and change the loading position of the luggage while guessing the rotation trajectory of the hinge arm.

  The present invention provides a vehicle trunk structure capable of checking in advance whether or not the hinge arm and the load interfere with each other without opening or closing the trunk lid while preventing the load from being hindered. For the purpose.

  The trunk structure for a vehicle according to the present invention is a trunk structure for a vehicle having a trunk lid supported at the vehicle body via a hinge mechanism so as to be freely opened and closed. The hinge mechanism is configured to rotate the trunk by a predetermined rotation. A hinge arm for opening and closing the lid, a hinge cover, and a restricting means are provided. One end of the hinge cover is pivotally supported on the vehicle body at the same pivot point as the hinge arm, and independently of the hinge arm. The hinge cover has a shape that follows at least the portion of the hinge arm that draws the lowest part of the rotation locus during the predetermined rotation, and the rotation of the hinge cover is controlled by the restriction means. The position of the hinge arm when the trunk lid is closed is restricted.

  According to this configuration, if the hinge cover is turned before closing the trunk lid, whether the hinge arm and the load interfere with each other when closing the trunk lid can be determined without actually opening and closing the trunk lid. This can be confirmed in advance based on the pivot trajectory of the hinge cover.

  Further, if the hinge cover is in the way when the luggage is taken in and out, interference between the luggage and the hinge cover can be avoided by appropriately rotating the hinge cover upward. As a result, it is possible to prevent the load from being hindered.

  Furthermore, by restricting the rotation of the hinge cover by the position of the hinge arm when the trunk lid is closed, the hinge cover can be prevented from entering to a position where there is no possibility of interference between the hinge arm and the load. For this reason, it can prevent that the loading area | region of a luggage | load is restrict | limited by this hinge cover, and can prevent the trouble in loading a luggage | load.

  In one embodiment of the present invention, the hinge cover is detachably connected to the hinge arm at a position different from the pivot point.

  According to this configuration, by connecting the hinge arm and the hinge cover, the hinge cover can be rotated upward in conjunction with the hinge arm when the trunk lid is opened. For this reason, it is possible to reliably avoid the interference between the luggage and the hinge cover when the luggage is taken in and out.

  On the other hand, if the connection between the hinge arm and the hinge cover is released, the hinge cover can be rotated independently of the hinge arm, so whether the hinge arm and the baggage interfere with each other when the trunk lid is closed. The trunk lid can be confirmed in advance based on the pivot trajectory of the hinge cover without actually opening and closing the trunk lid.

  In one embodiment of the present invention, the hinge cover is held at a position when the trunk lid is closed when the trunk lid is opened.

  According to this configuration, since the hinge cover can be prevented from rotating in conjunction with the hinge arm when the trunk lid is opened, it is necessary to rotate the hinge cover when, for example, the load clearly does not interfere with the hinge arm. It is possible to prevent the hinge cover from rotating when there is not.

  According to the present invention, it is possible to confirm in advance whether the hinge arm and the load interfere with each other without opening and closing the trunk lid, while preventing the load from being hindered.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing a rear portion of a vehicle body provided with a vehicle trunk structure according to an embodiment of the present invention. The vehicle body 1 shown in FIG. 1 corresponds to a trunk room TR disposed in the rear portion thereof. A trunk lid 2 as shown in FIG. The trunk lid 2 is connected to and supported by the vehicle body through a pair of left and right hinge mechanisms 3 (only one of which is shown in FIG. 1). In the drawing, the arrow (F) indicates the front of the vehicle body, and the arrow (R) indicates the rear of the vehicle body.

  As shown in FIGS. 1 and 2, the hinge mechanism 3 includes a base bracket 6 (see FIG. 3) fixed to a rear package tray 5 on the vehicle body 1 side that extends horizontally below the rear window 4, and the base bracket 6. A hinge arm 8 and a hinge cover 9 that are pivotally supported on the vehicle body 1 at the same pivot point by the shaft 7 are provided.

  The hinge arm 8 is a hollow cylindrical member, and a curved portion 8a is formed on one end side supported by the shaft 7, while the front end portion of the trunk lid 2 is fixed on the other end side. In the present embodiment, the trunk lid 2 can be opened and closed as shown in FIGS. 2 and 5 by a predetermined rotation with the shaft 7 of the hinge arm 8 as a fulcrum as shown by a two-dot chain line in FIG. It can be done. By forming the curved portion 8a on the hinge arm 8, the hinge arm 8 can be rotated while avoiding interference between the hinge arm 8 and the rear package tray 5 on the vehicle body 1 side when the trunk lid 2 is opened and closed. It can be done.

  On the other hand, the hinge cover 9 is formed, for example, by forming a slight gap between the hinge cover 9 and the shaft 7 or by providing a bearing, as shown by a two-dot chain line in FIG. It is possible to rotate independently of 8.

  Further, as shown in FIGS. 2, 3, 5, and 6, the hinge cover 9 is formed with a regulated portion 9 a that is convex in a side view, and the regulated portion 9 a As shown in FIG. 3, the base bracket 6 can come into contact with a restricting portion 6 a formed at the front portion of the vehicle.

  The hinge cover 9 is restricted from rotating forward of the vehicle at the position of the hinge arm 8 (position shown in FIG. 2) when the trunk lid 2 is closed when the restricted portion 9a contacts the restricting portion 6a. It is like that. The hinge cover 9 is held in the above position by the weight of the hinge cover 9 regardless of whether the trunk lid 2 is opened or closed unless a rotation operation described later is performed.

  The hinge cover 9 has a shape along a part of the hinge arm 8 as shown in FIGS. 1 to 3, 5, and 6, and a cross-section in which the upper part is opened as shown in FIG. 7. It is U-shaped. Thus, when the hinge cover 9 is at the same position as the hinge arm 8, as shown in FIGS. 1 and 2, both side surfaces and a part of the lower surface thereof are covered.

  In particular, in the present embodiment, as shown in FIG. 4, when the trunk lid 2 is in the closed position, the part 8b of the hinge arm 8 is set so as to draw the lowermost part of the turning locus, and the hinge cover 9 is At least, it has a shape along the portion 8b of the hinge arm 8 that draws the lowermost part of the turning locus during the predetermined turning.

  Thus, in this embodiment, the hinge cover 9 is rotated before the trunk lid 2 is closed by providing the hinge cover 9 having a shape along the portion 8b of the hinge arm 8 that draws the lowermost part of the rotation trajectory. If the operation is performed, whether or not the hinge arm 8 and the load loaded in the trunk room TR interfere with each other when the trunk lid 2 is closed can be determined based on the turning locus of the hinge cover 9 without actually opening and closing the trunk lid 2. This can be confirmed in advance.

  Further, when the hinge cover 9 is in the way at the time of loading / unloading the luggage, the hinge cover 9 can be appropriately rotated upward to avoid interference between the luggage and the hinge cover 9. As a result, it is possible to prevent the load from being hindered.

  Further, by restricting the pivoting of the hinge cover 9 toward the front of the vehicle by the position of the hinge arm 8 when the trunk lid 2 is closed, the hinge cover 9 is hinged to a position ahead of the vehicle where there is no possibility of interference between the hinge arm 8 and the load. It is possible to prevent the cover 9 from entering. For this reason, it can prevent that the loading area | region of a load is restrict | limited by this hinge cover 9, and can prevent the trouble in loading a load.

  Further, the hinge cover 9 is held in the closed position of the trunk lid 2 when the trunk lid 2 is opened. In this case, since the hinge cover 9 can be prevented from rotating in conjunction with the hinge arm 8 when the trunk lid 2 is opened, the hinge cover 9 is operated to rotate when the luggage clearly does not interfere with the hinge arm 8. It is possible to prevent the hinge cover 9 from rotating when it is not necessary. Thereby, the effect that the abrasion between the axis | shaft 7 and the hinge cover 9 can be suppressed is acquired, for example.

  8 and 9 show another embodiment of the vehicle trunk structure according to the present invention. In the embodiment shown in FIGS. 8 and 9, the hinge cover 9 is detachably connected to the hinge arm 8 at a position different from the shaft 7 by a hook member 10. 8 and 9, the same components as those of the previous embodiment shown in FIGS. 1 to 7 are denoted by the same reference numerals and description thereof is omitted.

  In this embodiment shown in FIG. 8 and FIG. 9, a hook member 10 as a connecting means is provided on the hinge cover 9, and this hook member 10 has an uneven-shaped operation portion 10a and a hook claw 10b. ing. The hook member 10 is constantly biased toward the other end (free end) of the hinge cover 9 by a biasing means such as a spring or a leaf spring (not shown).

  Further, the hinge cover 9 is provided with a slide hole 9b corresponding to the position of the hook member 10 so as to be slidable. The hinge arm 8 has the same position corresponding to the slide hole 9b. The slide hole 8c is formed.

  In this embodiment, as shown in FIGS. 8 and 9, after a part of the hinge arm 8 is covered with the hinge cover 9, when the hook claw 10 b is inserted into the hollow part of the hinge arm 8, this is the hollow of the hinge arm 8. It is designed to be caught on the inner surface of the part. At this time, the hinge arm 8 and the hinge cover 9 are sandwiched between the operation portion 10a and the hook claw 10b, so that the hinge arm 8 and the hinge cover 9 are connected. Yes.

  In this manner, by connecting the hinge arm 8 and the hinge arm 9, the hinge cover 9 can be rotated upward in conjunction with the hinge arm 8 when the trunk lid 2 is opened. For this reason, it is possible to reliably avoid interference between the luggage and the hinge cover 9 when the luggage is taken in and out.

  On the other hand, when the operation portion 10 a is slid against the urging force of the urging means, the hook claw 10 b can be extracted from the hollow portion of the hinge arm 8. Thereby, the connection between the hinge arm 8 and the hinge cover 9 can be released, and the hinge cover 9 can be rotated independently of the hinge arm 8 as in the previous embodiment.

  For this reason, also in the present embodiment, whether or not the hinge arm 8 and the load interfere with each other when the trunk lid 2 is closed depends on the turning locus of the hinge cover 9 without actually opening and closing the trunk lid 2. This can be confirmed in advance.

  In the present embodiment, similarly to the previous embodiment, the restricted portion 9 a is formed on the hinge cover 9. For this reason, when the connection between the hinge arm 8 and the hinge cover 9 is released, the hinge cover 9 can be used when the trunk lid 2 is opened or closed as long as the above-described rotation operation is not performed. The hinge arm 8 is held at the closed position. Therefore, when the connection is released, the hinge cover 9 is held in the closed position of the trunk lid 2 when the trunk lid 2 is opened.

  The connecting means is not necessarily limited to the hook member 10 described above. For example, a magnet or a hook-and-loop fastener may be used as long as the hinge arm 8 and the hinge cover 9 are detachably connected. May be.

  FIG. 10 shows still another embodiment of the vehicle trunk structure according to the present invention. In the embodiment shown in FIG. 10, the part 58b of the hinge arm 58 is set so as to draw the lowermost part of the turning locus while the trunk lid 2 is being opened and closed, that is, while the hinge arm 58 is turning. In FIG. 10, the same components as those in the previous embodiment shown in FIGS.

  Even in such a case, as shown in FIG. 10, the hinge cover 59 has at least a shape along the part 58 b of the hinge arm 58 that draws the lowest part of the turning locus at a predetermined turning time. Thus, whether or not the hinge arm 58 and the load interfere with each other when the trunk lid 2 is closed can be confirmed in advance based on the turning locus of the hinge cover 59 without actually opening and closing the trunk lid 2. it can.

  Other functions and effects are the same as those of the previous embodiment.
