Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a drive device for an opening/closing body suitable for opening/closing an opening/closing body such as an automobile sunshade.

[Conventional technology]

In general, T-bar roof vehicles have a structure in which when the left and right hatch panels (glass) are removed, the left and right roof openings are left largely open, leaving the center roof part, as shown in Japanese Patent Application Laid-Open No. 55-148658. It's summery.

[Problem that the invention attempts to solve]

As mentioned above, the left and right hatch panels are removable and, when installed, are transparent so that the outside can be seen from inside the vehicle. For this reason, when sunlight is strong, measures are taken to prevent sunlight from directly entering the passenger compartment using sun shades.

Since the sun shade is a removable type that can be attached and removed as needed on the back of the hatch panel, it is desirable to be able to open and close it using a drive device, since it is very troublesome to install and remove the sun shade. However, since the left and right sun shields were driven simultaneously, the device was complicated and it was difficult to make it compact.

Therefore, the object of this invention is to provide a drive device for opening/closing bodies that is compact in structure and allows smooth opening and closing of each opening/closing body.

[Means for solving problems]

In order to achieve the above object, in this invention, the first and second gears are meshed with a drive gear that can rotate forwardly and reversely by the power of a drive motor, and are opposed to the first gear and the second gear, and , third and fourth gears rotatable together are provided, and the first and second driving bodies are connected to an opening and closing body on one side of the third and fourth gears, and the first and second driving bodies are connected to another opening and closing body on the other side. The third and fourth driving bodies are engaged with each other.

[Effect]

In such an opening/closing body drive device, the third and fourth
The gear is driven by one drive motor, and each of the four driving bodies meshing with the third and fourth gears is extended, and two of the extended driving bodies are connected to one side of the sunshade, etc. By connecting both ends of the opening/closing body and further connecting the remaining two driving bodies to both sides of another opening/closing body, both ends of the opening/closing body can obtain equal traction. Furthermore, since the drive section can be handled by one motor, the structure becomes compact.

The sunshade 15 is made of synthetic resin and consists of a plurality of louvers 29.

Each louver 29 of the sun shade 15 is the first,
It has second protrusions 31, 33 and a long hole 35, and has a long hole 3.
The respective protrusions 31 and 33 are engaged with each other within 5 to ensure a connected state.

That is, the first and second protrusions 31 and 33 are provided at both ends of each louver 29 having upward and downward inclined surfaces 29a and 29b, and in the overlapping area where each louver 29 overlaps, for example, the first protrusion (see FIG. The second protrusion 33 of the louver 29 on the lower side engages with the elongated hole 35 of the second louver 29 (on the upper side in the figure). Further, the first protrusion 31 of the second louver 29 is engaged with the elongated hole 35 of the first louver 29. Hereinafter, in the overlapping area of each louver 29, the first and second protrusions 31, 3 of each louver 29
3 has a structure that engages with a long hole 35 of the next louver 29.

The sunshade 15 is in an operating state in which the roof opening 7 is closed by the driving device 41 (solid line in FIG. 9) and in an inoperative state in which it is stored in the storage portion 61 of the center roof portion 9 (solid line in FIG. 8). The operation is controlled accordingly. The drive device 41 includes each sunshade 15,
The four first ones each extending from both ends of 15,
Second, third, fourth driving bodies 43a, 43b, 45
a, 45b (hereinafter referred to as geared cable),
Each geared cable 43a, 43b, 45a, 4
A pair of third and fourth gears 47, 47 meshing with 5b

The terminals of the geared cables 43a, 43b, 45a, 45b that mesh with the third and fourth gears 47, 47a are fixed to both sides of the louver 29 located at the outermost side of the sunshade 29 via brackets 53, 53. .

The drive gear 51 is attached to an output shaft 57 of a reducer 55 that reduces the rotational power of the motor M and outputs it, and the motor M is controlled by a hand switch (not shown) to freely rotate in forward and reverse directions.

On the other hand, the opening 61a side of the storage section 61 provided inside the center roof section 9 is continuous with the guide section 17 of the guide rail 13. Storage section 61
is provided with a plate 65 that slides vertically by a pair of shafts 63, 63. The plate 65 is always urged upward by the urging spring 67, and at the uppermost position, the upper surface 65a of the plate 65 is positioned substantially on the same plane as the rail surface 17a of the guide portion 17.

Note that 71 indicates head lining.

In the drive device configured in this way, for example, in order to store the sun shades 15, 15 that are blocking the roof openings 7, 7, the motor M is driven and its rotational power is transmitted through the reducer 55. It is conducted to each of the first and second gears 49, 49a. The first and second gears 49, 49a rotate counterclockwise, and the geared cables 43a, 43b, 45a, 45b that mesh with the third gear 47 and fourth gear 47a move in the direction of arrow A, and the louver 29 Tow both ends at the same time. Therefore, the louver 29 reliably slides within the guide portion 17 without being deformed, and is successively pushed out from the innermost louver 29 to the upper surface 65a of the plate 65 of the storage portion 61. At this time, the downwardly inclined surface 29a of the next louver 29 is the same as the upwardly inclined surface 29a of the previous louver 29.
It ran onto 9b. As a result, the plate 65 descends against the biasing spring 67 as shown by the chain line in FIG.
Fold on top of 9.

In this case, since each of the protrusions 31 and 33 slides within the elongated hole 35, each louver 29 will be folded over with difficulty. Hereinafter, the same operation will be repeated to store the motor M, which will be the power source at this time.

Next, in order to pull out the stored sunshade 15 in the inoperative state and put it into the operating state, the geared wires 43a, 43b, 45a, and 45b are moved in the opposite direction to arrow A. As a result, the first and second protrusions 31 and 33 come into contact with the edge of the elongated hole 35, and each louver 29 is brought into contact with the edge one by one from the storage part 61, and each louver 29 is sequentially moved one by one from the storage part 61. Pull out. At this time, the plate 29 is pulled out and simultaneously raised one step at a time, and each louver 29 is smoothly guided through the guide portion 17, and the last louver 29 is pulled out from the storage portion 61 without any trouble.

In this embodiment, a geared cable was used as the driver, but a tape may also be used. In this case, the third and fourth gears become sprockets that can engage with the tape engagement hole.
