BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slope device for a vehicle, and more particularly to an improvement in the structure thereof.

[0002]

2. Description of the Related Art There is a vehicle equipped with a slope device for enabling a person to get on and off a vehicle in a wheelchair.
One example is shown in JP-A-108867. In this slope device, two slope plates are provided in a rear opening of a vehicle, and these slope plates are developed evenly by a spring force to form a ramp for getting on and off between a lower edge of the rear opening and a road surface.
Then, the drive wire locked to the road surface side slope plate is wound by an electric winding drum, so that the two slope plates are bent into a mountain shape, folded in two, and stored in the rear opening in an upright posture. According to this structure, the slope plate can be automatically deployed to the use position or folded to the storage position, so that labor can be reduced.

[0003]

However, the conventional slope device described above has a problem that the drive wire extends to the road surface side slope plate, so that the appearance is poor. Also, because the slope plate is relatively large, the storage height is high,
There is a problem that the rear view becomes narrow. Further, in recent years, there is a slope device in which a part of a slope plate is used as a tailgate. However, in the above-described conventional slope device, the outermost surface in the storage position is a slope surface (running surface).
Therefore, there is a problem that it cannot be applied to such a slope device.

Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a vehicle which can improve the appearance, can secure a good rear view, and can use a part of a slope plate as a tailgate. To provide a slope device.

In the first aspect of the invention, when the slope member is stored, the second slope member is turned over and folded on the developed first slope member. Then, in this state, the first slope member is rotated to a substantially vertical posture to be in the housed state. When a slope is formed, the first slope member is deployed outwardly of the opening, and then the second slope member is deployed outwardly of the opening. Note that a series of operations for storing and deploying such a slope member are performed by the control unit. As described above, the slope member can be automatically deployed to the use position or folded to the storage position, so that labor can be reduced. The driving means is

In this case, the driving torque is amplified by the principle of leverage by connecting the outer circumferences of the motors with the connecting members. Therefore, a sufficient rotational force is applied to the rotating shaft by the small drive motor, and the second slope member can be quickly rotated. Further, by disposing the driven gear in parallel with the slope surface of the first slope member, a large driven gear can be disposed compactly.

When the fixed pulley 58 supported on the support shaft 581 provided on the side of the tailgate 2 (FIG. 3) is rotated counterclockwise by the wire 52 and the slope plate 3 integrated therewith is rotated upward, the slope plate 3 is rotated. The fixed pulley 63 provided on the support shaft 631 moves on a circular locus about the support shaft 581, and along with this movement, one end of the wire 65 suspended on the stationary fixed pulley 61 is unwound. Gradually pulled out. As a result, the fixed pulley 63 provided integrally with the slope plate 4 receives the weight of the slope plate 4 and rotates clockwise downward together with the slope plate 4 so as to wind up the drawn wire 65. In this way, as the slope plate 3 rotates counterclockwise, the slope plate 4 connected to its tip rotates clockwise.

It meshes with the outer peripheral tooth shape of the driven gear 151 fixed to the end of the shaft 1261. Bracket 15 above
A pulley 61 (FIG. 18) is fixed to the tip end plate surface concentrically with the gear 158. On the other hand, a support shaft 631 is provided on the lower surface on both sides of the end of the slope plate 3, and the fixed pulley 63 is provided on this. It is rotatably supported. Fixed pulley 6
The base 3 of the slope plate 4 is integrally fixed to 3. A wire 65 is suspended between the fixed pulleys 61 and 63.

When the gear 158 and the bracket 153 integrated therewith are rotated counterclockwise by the driven gear 151 provided on the tail gate 2 (FIG. 15) side, and the slope plate 3 rotates upward, the slope plate 3 Support shaft 6
The fixed pulley 63 provided on the base 31 moves on a circular locus about the support shaft 1581 (see FIG. 18), and with this movement, the wire 65 suspended on the stationary fixed pulley 61 is stopped.
One end is unwound and gradually pulled out. As a result,
The fixed pulley 63 provided integrally with the slope plate 4 receives the weight of the slope plate 4 and rotates clockwise downward together with the slope plate 4 so as to wind up the drawn wire 65. In this way, as the slope plate 3 rotates counterclockwise, the slope plate 4 connected to its tip rotates clockwise.

FIG. 19 shows the drive mechanism 12 of the tail gate 2.
4 is shown in detail. A bracket 1247 is provided in the recess W1 (FIG. 14) in the side wall of the passenger compartment so as to be covered by a cover plate 1246. The bracket 1247 is formed in a substantially gourd shape in plan view, and has a circular portion on the rear side. At the center, a support shaft 1245 is rotatably provided upright. The support shaft 12
The center of a fan-shaped driven gear 1241 is fixed to 45 so as to be vertically rotatable.
An arm 1242 extends obliquely rearward and upward from the center of the arm, and a base end of a link arm 22 is rotatably connected to the end thereof. A gear box 1248 of the drive motor 1243 is held in a circular portion on the front side of the bracket 1247, and an output shaft 1249 protruding from the gear box 1248.
Protrudes from the center of the circular portion, and the pinion gear 1244 mounted on the tip of the circular portion meshes with the outer peripheral tooth shape of the driven gear 1241. When the pinion gear 1244 is rotated to rotate the driven gear 1241 forward and backward, the link arm 22 is moved in the front-rear direction, and the tailgate 2 is opened and closed.

In the slope device having such a structure,
The use state in which the tailgate 2 and the slope plates 3 and 4 are all developed outside the opening O to form a slope (FIG. 2)
In step 0), the user enters the wheelchair into the passenger compartment, and then drives the motor 1
When the driven gears 123A and 123B are turned at 233 (FIG. 16) to rotate the rotating shaft 126 clockwise in FIG. 20, the driven gear 151 and the gear 158 meshing with the driven gear 151 are rotated.
The slope plate 3 rotates upward in a counterclockwise direction through the slope plate 4 and the slope plate 4 connected to the tip of the slope plate 3 accordingly.
Rotates clockwise by its own weight (FIG. 21). Further, when the slope plate 3 is rotated counterclockwise and folded on the tailgate 2, the slope plate 4 rotating clockwise is folded so as to overlap the folded slope plate 3. (Figure 2
2). Thereafter, when the driven gear 1241 is turned counterclockwise in FIG. 22 by the drive motor 1243 (FIG. 19), the link arm 22 is pulled forward (to the left in FIG. 22), and the lower opening O2 is opened by the tailgate 2. While being closed (FIG. 23), the slope plates 3 and 4 are compactly stored behind the tailgate 2 in a folded state. Therefore, it is easy to put the luggage in and out of the luggage compartment. Also, since the wires are not exposed as in the conventional case, the appearance is good. When the back door D (FIG. 13) is closed with the tailgate 2 in a substantially vertical posture, the bumper central portion 13 attached to the lower end of the door is located along the outer surface of the tailgate 2 and the left and right bumper side portions 11, Continues with 12.

In each of the above embodiments, the slope device in which the two slope plates 3 and 4 are connected to the tip of the tailgate 2 has been described. However, a structure in which only one slope plate 3 is connected may be used. Does not require the fixed pulleys 61 and 63, the wire 65, and the like that constitute a drive mechanism for folding the slope plate 4.

As described above, according to the vehicle slope device of the present invention, the appearance is improved because the drive wire is not largely exposed.
