Embodiment An embodiment of the tailgate structure according to the present invention will be described with reference to the drawings.

1 and 2 show a rear portion of a vehicle to which the tailgate structure of the present invention is applied. The tailgate 1 is installed in the rear part of the vehicle body 2, and the rear window 3 is mounted on the upper part of the tailgate 1. Further, an opening 6 is formed between the lower end 4 of the tailgate 1 and the rear lower edge 5 of the vehicle body 1, and the lower end 4 of the tailgate 1 is usually lifted or lowered to cover the opening 6. A body panel 7 is supported.

The tailgate 1 is rotatably supported with a back door hinge 8 provided at an upper rear portion of the vehicle body 2 as a fulcrum, and extends from a closed position shown in FIG. 2 to an open position shown by a chain double-dashed line 9. It is designed to be rotationally displaced. The tailgate 1 is biased in the opening direction by a torsion bar (not shown) engaged with the back door hinge 8. This reduces the operating force when opening the tailgate 1 and holds the tailgate 1 that has been raised to the maximum open position at the raised position. On the other hand, when the tailgate 1 is in the closed state, the tailgate 1 is locked to the vehicle body 2 by a locking mechanism (not shown) so that the tailgate 1 will not be opened unexpectedly during traveling.

Below the rear window 3 mounted on the tailgate 1, an inner panel 10 and an outer panel 11 extending downward from the lower end of the rear window 3 are provided in the left-right direction of the vehicle. A storage portion 12 for the lifting body panel 7 is formed between the panel 10 and the outer panel 11. The storage portion 12 is provided with a pair of left and right guide rails 13 extending in the up-down direction, and an elevator panel 7 is supported by the guide rails 13 so as to be vertically movable.

As shown in FIGS. 3 and 4, support mechanisms 19 are provided on both upper sides of the side of the lifting body panel 7, and the support mechanisms 19 are inserted into the grooves 20 of the guide rails 13. The lifting body panel 7 is supported by the guide rails 13. The support mechanism 19 includes a pair of support rollers 15 attached to the elevating body 7 via a pair of support shafts 14 provided at upper side portions of the elevating body panel 7 at predetermined vertical intervals, and the pair of supporting rollers 15 A fixed shaft 16 provided at an intermediate position, a spring 17 fixed to the fixed shaft 16 and extending in the vertical direction, and sliding bushes 18 arranged at both upper and lower ends of the spring 17, respectively. The roller 15 slides along the inner wall of the guide rail 13 on the front side of the vehicle, while the sliding bush 18 slides along the inner wall of the guide rail 13 on the rear side of the vehicle. Further, since the lifting body panel 7 is configured to be biased toward the front of the vehicle by the spring force of the spring 17, the lifting body panel 7 can be raised and lowered without rattling with respect to the guide rail 13. ing.

Further, the tip end of a cable 22 that is operated to move up and down by a drive motor (not shown) of the drive unit 21 is connected to the support shaft 14 of the support roller 15 on the upper side of the support mechanism 19. The drive portion 21 is provided below the rear window 3 as shown in FIG. 1, and is driven by operating an outdoor handle 23 provided at the center of the lower end portion of the tail gate 1. When the drive unit 21 is driven, the cable 21 is pulled upward, whereby the lifting body panel 7 rises from the closed position shown in FIG. 1 to the open position shown by the chain line 24, and the opening 6 is opened. The elevator panel 7 is stored in the storage section 12.

As shown in FIG. 5, the outdoor handle 23 includes a rotating arm 26 rotatably supported with a fixed shaft 25 as a fulcrum, and a knob 27 formed at the tip of the rotating arm 26. The rotating arm 26 has a convex portion 28 formed on the outer peripheral surface of the upper portion thereof. Further, at a position facing the upper peripheral surface of the rotating arm 26, a switch X for raising and lowering the lifting body panel 7 to open and close the opening 6, and a lock of the tailgate 1 are released. , And a switch Y for opening the tailgate 1 are arranged side by side in the circumferential direction. At this time, the switches X and Y and the convex portion 28 are arranged such that when the rotary arm 26 is rotated counterclockwise by the angle θ ₁ (position of the broken line 29), the convex portion 28 reaches the switch X. Is turned on, the angle θ _{2 is} rotated, and the convex portion 28 reaches the switch Y so that the switch Y is turned on.

In the tailgate 1 having the above structure, when the elevator panel 7 is moved up and down to open and close the opening 6, first, the outdoor handle 23 is rotated by an angle θ ₁ and the switch X is turned on. When a preset time T elapses after the switch X is turned on, the drive unit 21 is operated, the lifting body panel 7 is driven to rise, and the opening 6 is opened. To close the opening 6, the outdoor handle 23 is rotated again by the angle θ ₁ and the switch X is turned on again. At the same time when the switch X is turned on, the elevator panel 7 is lowered and the opening 6 is closed by the elevator panel 7.

On the other hand, when the tailgate 1 is opened and closed, the outdoor handle 23 is rotated beyond the angle θ ₁ by an angle θ ₂ or more and the switch Y is turned on, thereby locking the lock mechanism. To cancel. As a result, the rear part of the vehicle can be opened by manually flipping the tailgate 1 upward. When the tailgate 1 is closed, the tailgate 1 is manually rotated downward and pressed against the rear portion of the vehicle body 2, whereby the tailgate 1 is locked by the lock mechanism to be in the closed state.

Here, when the tailgate 1 is opened, the outdoor handle 23 is rotated and the switch X is turned on, and then the switch Y is turned on. However, the switch X is turned on and the switch Y is turned on. The switch Y is turned on within a preset time T until the drive unit 21 starts its operation, so that the drive unit 21 is not operated. In other words, the time T from when the switch X is turned on to when the drive unit 21 starts to operate is the time T when the outdoor handle 23 is normally rotated by the angle θ ₂ and when the switch X is turned on and then the switch Y is turned on. By setting the time sufficiently longer than the time until the switch is turned on, the lock release of the tailgate 1 and the lifting operation of the lifting body panel 7 are not performed at the same time.

In this way, the opening 6 is provided between the tailgate 1 and the rear lower edge 5 of the vehicle body 2, and the elevator panel 7 is moved up and down to open and close the opening 6. Therefore, it is possible to load and unload cargo without opening the tailgate 1 in situations where there is not enough space for loading and unloading small luggage or opening the tailgate 1 behind the vehicle. There is an advantage.

Further, when the opening 6 is opened as in the embodiment, the lifting body panel 7 is housed in the housing 12. Therefore, when the opening 6 is opened, the lifting panel 7 is moved to the vehicle. It does not interfere with the baggage inside.

In the above embodiment, the operation of opening the tailgate 1 and the operation of opening the lifting body panel 7 cannot be performed at the same time. However, when the lifting body panel 7 is raised, the tailgate 1 is opened. If the gate 1 can be opened, the opening trajectory of the tailgate 1 can be made smaller, and the tailgate 1 can be opened even when loading and unloading luggage in a place where the vehicle rear is narrow. .

In addition, in the embodiment, the opening 6 is provided between the tailgate 1 and the rear lower edge 5 of the vehicle body 2, but as shown in FIGS. A tailgate 31 that covers up to the rear lower edge 41 of the rear window 31 may be applied, an opening 33 may be provided on the entire lower surface of the rear window 32, and the elevator panel 34 may be moved up and down to open and close the opening 33. . In this case, the opening 33 is provided in the double wall portion 37 including the inner panel 35 and the outer panel 36, and the opening / closing body panel 34 is moved up and down in the double wall portion 37 to open and close the opening 33. At this time, for example, if a panel outlet 38 is provided above the inner panel 35 and a guide means for guiding the elevator body panel 34 to the panel outlet 38 is provided, when the opening 33 is opened, the elevator 33 is lifted. The body panel 34 is slid so as to project upward from the panel outlet 38 of the double wall portion 37, as shown by the chain line 39 in FIG. 7. According to this configuration, when opening the opening 33, it is not necessary to secure the storage portion for storing the lifting body panel 34, so that the opening 33 can be widely provided and a larger cargo can be loaded and unloaded. There is an advantage that you can do it.
