Abstract

PURPOSE:To make the opening/closing locus of the title device smaller by providing a sliding body which ascends or descends to a guide member provided on an upper opening/closing body side in a state where the movement of the sliding body is interlocked with that of the upper opening/closing body and attaching one end of an actuating member to the sliding body, with the other end of the sliding body being attached to a lower opening/closing body. CONSTITUTION:When an opening/closing body 5 is manually opened, a sliding body 65 rises along the second guide member 29 and raises an actuating member 72 upward and a lower opening/closing body 5b rises along a rotating locus (a) while it rotates. When a driving motor is rotated in the normal direction by operating a switch at hand, an actuator starts to work and unlock a locking device. Then the first slider 43 of a driving member 39 rises and pushes the second slider 41 upward and, as a result, a latch and striker rise in a state where they are engaged with each other. Moreover, an upward pressing action is applied to a lower-side link 69 and an upper-side link 67 rotates outward around a pin P2. As a result, the opening/closing body 5 and sliding body 65 smoothly rotate upward.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an automatic opening/closing device for an opening/closing body suitable for a back door of an automobile or the like.

(Prior art) In general, in the case of an opening/closing body such as a one-box type back door, an open state can be obtained by flipping upward using the hinge as a fulcrum, and a fully closed state can be obtained by rotating downward. It looks like this.

(Problems to be Solved by the Invention) As mentioned above, opening/closing bodies such as one-box type back doors are opened and closed using hinges as fulcrums. It is ensured that it can jump upwards significantly so that it does not get in the way. At this time, the back door rotates around the hinge and draws a large opening/closing trajectory, so for example, it is difficult to open and close in a narrow space. This caused problems such as restrictions.

Therefore, it is an object of the present invention to provide an automatic opening/closing device for an opening/closing body that can be opened/closed while drawing a small opening/closing locus.

[Structure of the invention] (Means for solving the problem) In order to achieve the above-mentioned 11 objectives, this invention has the following features:
', the fixed hinge is moved to the fulcrum by a driving means or manually.1. In the opening/closing body that can be flipped upward with the opening/closing body,
It is formed of an upper opening/closing body and an F section opening/closing body that are rotatable about a rotation hinge as a fulcrum, and a guide member provided on the side of the upper opening/closing body is raised in conjunction with the opening operation of the two-part opening/closing body. A sliding body is provided which moves down in conjunction with the closing operation of the door, one end of the operating member is rotatably connected to the sliding body, and the other end is rotatably connected to the lower opening/closing body. .

(Function) In such an automatic opening/closing device for an opening/closing body, when the opening/closing body is opened, the sliding body slides upward in conjunction with the opening operation, and pulls the operating member upward.

- As a result, the lower opening/closing body rises while rotating inward, so the opening/closing body opens with its opening/closing trajectory kept small. .

On the other hand, when the opening/closing body is closed, the sliding body slides downward in conjunction with the door closing operation, and presses the operating member downward. ,−
As a result, the lower opening/closing body rotates outward (12) and descends, so that the opening/closing body closes the door with its opening/closing locus being pushed slightly.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings of FIGS. 1 to 10.

An opening/closing body such as a flip-up type back door is provided. The opening/closing body 5 is formed of an upper opening/closing body 5a and a lower opening/closing body 5b, which are rotatable about the rotation hinge 6 as a fulcrum. The weight of the opening/closing body 5 is balanced by an assisting mechanism (not shown) such as a gas stay, and the opening/closing body 5 can be rotated from an open state (solid line in Figure 1) to the highest position (solid line in Figure 1) to a fully open state (dashed line in the Figure). When the opening/closing body 5 is fully opened, a locked state in which it is restrained by the locking device 7 and an unlocked state in which it can be opened and closed are obtained.

The locking device 7 has a latch 11 that removably engages with a striker 9 provided on the vehicle body 1 side when the opening/closing body 5 is fully opened. It can be rotated between an engaged state (full latch) and a partially closed state (half latch). The operation of the latch 11 in the half-latched state is controlled by an operating cable 15 extended from the closure device 13 to the full-latched state in which it is properly engaged, thereby preventing accidents due to the door being left ajar.

, ': The operation of the automatic opening/closing device configured as follows will be explained.

When the opening/closing body 5 is fully opened, the first and second sliders 43
．． 41 is in the uncoupled state, the lock device 7 will be in the unlocked state by operating the handle 20 without affecting the actuator 23, so the lock device 7 will be in the unlocked state.
Thus, the opening/closing body 5 can be opened and closed. This manual opening/closing body 5 is pasted and the sliding body 65 is attached to the second guide 1
7, the operating member 27 is pulled up in one direction, and the lower opening/closing body 5b is rotated inward as shown in FIG.
However, the space required for the upward rotation trajectory a is smaller than that of the conventional rotation trajectory. Also, when closed, it rotates in a similar trajectory.

When the opening/closing body 5 is opened or closed, the second slider 4 moves up and down along the nozzle 33 as shown in FIG.

Next, when the drive motor 37 is rotated forward by operating the hand switch, the actuator 23 is also activated, and the locking device W7 is unlocked. At the same time, the first slider 43 also rises, and when it is 1, -, the first slider 43 pushes the second slider 41, and the latch 1]- and the striker 9 rise while remaining in the engaged state. When the roller 5B or the guide 31 is removed, the latch 11 rotates from the chain line position to the solid line position as shown in FIG. The movement is restricted and the first, first .
