DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear body structure of a vehicle, and more particularly to a rear body structure of a vehicle in which a passenger compartment and a rear luggage compartment are partitioned by using a package tray as a tray member. It is.

[0002]

2. Description of the Related Art Conventionally, as represented by a wagon type vehicle, a vehicle rear luggage compartment communicating with a rear seat and a rear door for opening and closing a vehicle opening behind the vehicle are provided. 2. Description of the Related Art In a vehicle, at least a rear seat is made to be tiltable toward a front side of the vehicle so that a backrest of the rear seat can be used as a luggage loading surface continuous with a rear luggage compartment. In such a vehicle, a tray member called a package tray may be detachably provided above the rear luggage compartment, and when large luggage is not loaded, the crew compartment and the rear luggage compartment are separated by the tray member so that the crew compartment is not provided. The air conditioning performance and comfort are improved.

On the other hand, for example, according to Japanese Patent Application Laid-Open No. 06-70745, the rear seat is made to be tiltable toward the front of the vehicle, and the retractable tonneau cover is linked to the operation of tilting the rear seat to the front of the vehicle. It has been proposed to improve the air-conditioning performance and comfort of the passenger compartment by separating the passenger compartment from the rear luggage compartment by a wind-up tonneau cover when large luggage is not loaded.

[0004]

However, according to the proposal of the above-mentioned publication, since the tonneau cover is made of a sheet-like material, it is not possible to load luggage thereon.
It simply stops the passenger compartment from the rear luggage compartment.

[0005] Therefore, the present invention has been made in view of the above-mentioned problems, and is intended to provide a state in which the passenger compartment and the rear luggage compartment are separated by a tray member located above the rear luggage compartment. The traveling sound and vibration from the rear luggage compartment, which deteriorates the comfort of the passenger compartment, can be prevented from entering, and the tray member is moved in conjunction with the operation of tilting the rear seat toward the front of the vehicle. It is intended to provide a rear body structure of a vehicle which is excellent in usability such as loading and unloading of large luggage to / from a rear luggage compartment by making it usable as a luggage loading surface.

In this figure, the bearing member 31 is fixed to the above-mentioned concave portion 3b using a screw as shown in the figure, and makes the link member 30 rotatable in the direction of the arrow.

The hinge 37 shown in FIG.
Is fixed to the backrest 6a below the first tray member 8 shown by a broken line as shown in the figure, so that it can rotate in the direction of the arrow.

With the above configuration, the first tray member 8 and the second tray member 9 are folded in the direction of arrow D1 by the two hinges 16 in the front view for explaining the operation of FIG. Following this, the backrest 6a of the rear seat 6
Is moved in the direction of the arrow D2 in conjunction with the headrest 7 by a motor (not shown) disposed below the floor surface or manually, and at this time, the link member 30 and the backrest 6a,
As a result of the parallel link mechanism being formed between the rotation fulcrum member 29 and the first tray member 8 pivotally supported by the hinge 37, the first tray member 8 descends while moving in parallel. For this reason, even if the baggage M is loaded behind the backrest 6a of the rear luggage compartment 3, the first tray member 8 does not move thereon.

As described above, the second tray member 9 moved in the direction of arrow D2 and rotated by the hinge 37 so as to be superimposed on the first tray member 8 is connected to the floor 3a of the rear luggage compartment 3. A luggage room can be configured. Finally, FIG. 13 is an external perspective view showing a rear part in a half cross-sectional state when the rear body structure of the vehicle according to the fifth embodiment of the present invention is applied to a vehicle having an intermediate appearance between a sedan and a hatchback. is there. In the figure, the same reference numerals are given to the components already described, the description is omitted, and different configurations are described. In the fifth embodiment,
The tray member 40 (shown by broken lines) is moved independently of the operation of lowering the backrest 6a of the rear seat 6 to the left and right quarter trims 14.
It can be moved up and down in the direction of arrow D by a parallel link mechanism incorporated below. The parallel link mechanism is driven by a motor 38, and is connected to the floor 3 of the rear luggage compartment 3.
It is configured to stop at an arbitrary height H from a, allow loading of luggage at the stop position, and make the tray member 40 usable as a shelf board.

In order to achieve such a configuration, referring to the front view showing the rear luggage compartment of FIG. 14 and the cross-sectional view of FIG. 15, the lower side of the quarter trims 14 on both sides of the rear luggage compartment 3 will be described. A link member 33 and a link member 34 constituting a parallel link mechanism are provided rotatably at left-right symmetric positions, and both ends of the link member 33 are pivotally supported by pivot support members 35 and 38. The link member 34 fixed to the power source of the motor 38 is
Both ends are pivotally supported at 6, 38. These links 33 and 34 are connected to the rear luggage compartment 3 as shown in FIG.
Is arranged so as to rotate up and down in a slight gap formed between the side surface 3c of the tray member 40 and the side surface of the tray member 40, so that the space of the rear cargo room 3 is not affected. With the parallel link mechanism configured in this manner, the tray member 40 is moved in parallel between an upper position shown by a solid line in FIG. 14, an intermediate position shown by a one-dot chain line, and a lower position shown by a two-dot chain line.

FIG. 16A shows the rotation fulcrum member 38 described above.
3 is an exploded perspective view showing an example of the structure of the tray member 4 in the figure from the upper ends of the link members 33 and 34.
Rod bodies 33a and 34a each having a threaded portion toward 0 are fixed by caulking or the like. A pipe 38a that is rotatably supported after the rods 33a and 34a are inserted into the pivot fulcrum member 38 that is fixed to the four positions on the back surface of the tray member 40 as described above is fixed by welding or the like. ing. After inserting the rods 33a and 34a into this pipe 38a,
The flat washer 39 and the spring washer 42 are inserted, and the rod is finally screwed and connected using the nut 41 to complete the process.

FIG. 16B is a center sectional view showing an example of the structure of the rotation fulcrum member 35 of the link member 33, and FIG.
6 (c) is a right side view thereof. In this drawing, a rotation fulcrum member 35 having a flange formed at a lower end of a link member 33.
