Description

[Detailed description of the invention] The present invention relates to a novel sliding door opening/closing device for a vehicle.

Recently, in order to eliminate the door pocket and use the interior space more widely and more effectively, a type of sliding door that opens and closes along the outer surface of the car body wall while pushing it outward from the vehicle entrance (hereinafter referred to as the push-open/close type for convenience) has been introduced. Vehicle sliding door opening/closing devices (mentioned above) have been developed. By the way, the conventional push-opening/closing type sliding door opening/closing devices generally employ rotating push-out arms as means for pushing out the sliding door, or Most of them use curved guide rails or a combination of these.
In both devices, when opening a sliding door, the sliding door is pushed out, the operation and the opening operation are performed at the same time, and the sliding door is opened by the combined movement of both. It is designed to be closed by a combined action with the retracting action. However, as mentioned above, in conventional opening/closing devices in which the pushing and retracting operations of the sliding door are not separated from the opening/closing operations, when the sliding door begins to open and closes, the seal pads on the upper, lower, left, and right edges of the vehicle entrance In other words, the seal, which maintains the airtightness of the passenger compartment by being in pressure contact with the sliding door in the closed state, is rubbed in the direction of the combined movement by the sliding door, and therefore wears out in a relatively short period of time.Furthermore, the seal When the sliding door finishes closing, the gasket is deformed by the sliding door in the direction of the synthetic movement, which tends to cause poor pressure contact with the sliding door, so it has the disadvantage that it is difficult to obtain a satisfactory airtightness.In addition, all of the above conventional devices Since the device is assembled on the spot by individually attaching the rotary extrusion arm, guide rail, other components, and drive means to the vehicle body, various installation processes must be performed on the vehicle body9. It also has the disadvantage that it takes a considerable amount of time to assemble the device because the processing is quite troublesome.

This invention was made in order to eliminate the various drawbacks of the sloping structure, and is configured so that the pushing and retracting operations of the sliding door are performed separately from the opening and closing operations, and the main components of the device are attached to the support plate. It is an object of the present invention to provide a vehicle sliding door opening/closing device in which the main part of the device is integrated.

Hereinafter, this F3A will be explained in detail based on drawings showing examples.

In FIG. 1, l is a movable support plate that serves as a base for installing and integrating the main components, and this movable support plate 1 has a cross section IIJ as shown in FIGS. 6, 8, etc. It consists entirely of metal profiles. At both ends of this movable support space l, slide bearings 12.12 are provided via L-shaped metal fittings A11.11', and these slide bearings 12.12 are arranged as shown in FIGS. 1 and 2. , a bearing bracket (13.13) protruding inwardly from the vehicle body wall B on both sides above the entrance/exit A is slidably fitted onto the shaft 14. Thus, the movable member 1
is housed inside the vehicle body wall B along the upper edge of the entrance A, and is capable of approaching and returning to the vehicle body wall B.

On both sides of the movable support pace 1 are shown FIG.

As shown in FIGS. 6 and 8, a pair of rails 2a+2b having a substantially C-shaped cross section are fixed back to back. As shown in FIGS. 1 and 8, one rail 2a holds four rotatable door wheels 41a+42at43a*44a provided on the sliding door hanger 4a of one sliding door 3a, and the other rail 2b holds four rotatable door wheels 41a+42at43a*44a. Sliding door hanger 4b of the other sliding door 3b
Four rotatable door wheels 41b, 42b, 43b provided with K
, 44b, 0 cars 41a, 42a, 43a
+44a, as shown in FIG. 8, are two substrates 45a.

These boards 45al and 46a are bolted to the arm plate 47a of the sliding door hanger 4a extending along the rail 2a. Bolt insertion holes 471 formed in the arm plate 47a
a + 472 a + 473 a + 474 a
Both are vertically long elongated holes, and the substrate 45a.

By finely adjusting the mounting position of 46b, the door wheels 41a and 43a located diagonally above can be adjusted to 1/-k 2 a (7
) The door rollers 42 a + 44 a located diagonally below are fitted and press-contacted to the lower concave groove 22 a of the rail 2 a, so that they can be installed while being adjusted respectively so that they fit and press into the upper concave groove 21 a. Therefore, the sliding door hanger 4a has a door wheel 41a+43a that rolls and travels in the upper groove portion 21a of the rail 2a, and door wheels 42a and 44a that rolls and travels in the lower groove portion 22a. Accordingly, it is possible to move along the rail 2a without causing any wobbling.

The other door rollers 4 lb, 42b, 43b, 44b are also attached to the arm plate 47b of the other sliding door hanging tool 4b via the substrates 45b, 46bk in the same manner as above, and the door rollers 41b, 4
3b connects the upper groove portion 21b of the other rail 2b to the door roller 4.
2b and 44b are adapted to roll and travel in the lower groove portion respectively.〇The sliding door hanger 4a housed in one of the sliding doors 3a, as shown in FIG. It fits between the provided arm plate 47a and the L-shaped hanging main body 48a bolted near one end of the arm plate 47a, and the vertical piece 481a of this hanging main body 48a is bendable in the middle. A mounting seat plate 483a is integrally formed at the tip of the horizontal piece 482a of the hanging main body 48a, which serves as a hinge. By attaching a bolt to one corner of the sliding door 3a, the sliding door hanging tool 4 can be suspended.
As shown in FIG. 1, the arm plate 47a11'i of a is largely deviated toward the sliding door 3b on the opposite side, and when the sliding door 3a is fully opened, the arm plate 47a is fully closed along the rail 2a. The sliding door 3a is moved to a position above the sliding door 3a. Therefore, as shown in FIG. 1, the rail 2a may be slightly shorter than the upper edge of the doorway A, and the movable support base l to which the rail 2ai is attached may also be slightly longer than the upper edge of the doorway A. In addition, since the vertical piece 481a of the hanging device main body 48a is bendable in the middle, even if the sliding door 3a is rotated in the front-back direction (in/out direction), the vertical piece 481a will not hold it. Absorb and arm plate 4

A pair of air cylinders 5.5 are attached as first driving means for pushing out the door 3b to the outside of the entrance/exit A and returning it. Both air cylinders 5.5 are oriented perpendicularly to the vehicle body wall B, and as shown in FIG.
It is connected and fixed with a pin 53. When pressurized air is supplied into the cylinder 5 from the port 54 on the car body wall side of the air cylinder 5, the piston rod 51 is drawn into the cylinder 5, so that the cylinder 5 is relatively close to the car body wall. B, and as a result of this movement, the movable support base 1 in the relationship between the cylinder 5 and the vehicle body wall B
It moves towards. When this approaching state occurs and pressurized air is supplied to the port 55 on the opposite side, the piston rod 51 protrudes and the cylinder 5 and movable support base l return to their original positions. When the movable support base l approaches and returns to the vehicle body wall B, the sliding door 3a suspended from the rails 2a*2b of the movable support base 1 via the sliding door hanging tools 4a+4b

The other rank 62a is moved in the opposite direction to the rack 62b by the j J HI', y3 ON 63 in which the rack 62b moves together with the piston rod 611. These racks 62a and 62b are arranged above and parallel to the arm plates 47a and 47b of the sliding door hangers 4a and 4b, respectively, and one rank 62a and the arm plate 4
7a1, the other rack 62b, and the arm plate 47b are connected and fixed via connecting members 65a and 65bi, respectively. Therefore, when the sliding door 3a + 3b is pushed out from the entrance A, one of the air cylinders 61 When pressurized air is supplied from the port and exhausted from the other port 613 and the piston rod 611 is pushed out, one rack 62b, the sliding door hanger 46, and the sliding door 36 connected to the piston rod 611 are connected to the piston rod 611. 6゛1
1 extrusion direction (to the left in FIG. 1), and at the same time, via the pinion 63, the other rack 62a and the sliding door hanging tool 4a.
Then, the sliding door 3a moves in the opposite direction (to the right in FIG. 1), and as a result, both the sliding doors 3a and 3b are opened left and right along the outer surface of the vehicle body wall B. In this open state, pressurized air is supplied from the port 613 of the air cylinder 61 and exhausted from the opposite port 612, and when the piston rod 611 is retracted, both the racks 62a, 62b and the sliding door hanger 4a
+ 4 b and the sliding doors 3a, 3b both move in the opposite direction to the above, thereby closing the sliding doors 3a, 3b.

Further, a pair of auxiliary means 7a, 7b are provided on both sides of the lower end of the entrance/exit A to assist in pushing out and returning the sliding doors 3a, 3b. The movable supporting pace 1 is configured to be interlocked with the movable support pace 1 through a pair of connecting means 8a and 8bi.

That is, as shown in FIGS. 1 and 7, the auxiliary means 7a consists of an L-shaped arm 73a having two rotatable rollers 71a72ak at its tip, and this arm 73a supports the rotatable rollers 71a and 72ak of the connecting means 8a. The roller 71a is fixed at right angles to the lower end of the vertical shaft 82a, and one roller 71a is fixed to the lower end of the vertical shaft 82a.
It is fitted into the lower guide groove 31a. A connecting means 8a for interlocking this auxiliary means 7a with the movable support pace 1 includes an upper and lower vertical shaft 81a+8 rotatably supported.

The distal end portion is connected to one of the fixed arms 15a of the fixed arms 15b by a pin 87-a. The bottle insertion hole of this fixed arm 15a is a normal round hole, but the arm 8
The pin insertion hole 6a is an elongated hole into which a bottle can slide. Therefore, when the movable support pace l moves toward the car body wall B, the arm 86a moves toward the car body wall B with the vertical axis 81ai as the center along with the vertical axis 812I. It is designed so that it can be rotated to When the arm 86a rotates in this way, the upper vertical axis 81a + oblique axis 85a and the lower vertical axis 82a rotate in the same direction, so that the L-shaped arm 7 fixed to the lower vertical axis 82a rotates in the same direction. '3a rotates in the same direction and by the same angle as the arm 86a and reaches the position shown by the dashed line in FIG.
This pushes the sliding door 3a out of the entrance A.
In this extruded state, when opening and closing the sliding door 3a as described above, the side plate 311a in front of the guide groove 31a of the sliding door 3a is moved by the two rollers 71a located diagonally to each other.
