Reference numeral 6 denotes a door drive device for fully opening the slide door 4, and a rack 8 having a length substantially equal to the sliding distance of the door 4 and having a predetermined width is fixed in the front and rear direction inside the door 2. On the other hand, an electric motor 10 is fixed to the body 2, and a pinion 12 is fixed to the output shaft via a reduction gear device (not shown). The motor 10 drives the pinion 12 to rotate. The pinion 12 is arranged at a position where it meshes with the rack 8 at its rear end in the closed state shown in FIG. Because of this motor 10
When a drive current flows to the pinion 12, the pinion 12 rotates and the slide door 4 moves along the rail 14 in the door opening direction. That is, in this embodiment, the door drive device 6 is configured by the rack 8, the pinion 12, the rail 14, the electric motor 10, and the like. As will be described later, this door drive device 6 is a detector (curtain switch) for detecting the minute open state of the slide door.
When the 16 is turned on, the operation starts and the sliding door 4
Is configured to slide in the door opening direction.

Reference numeral 18 in the drawing denotes an electric actuator that locks the door 4 at the closed position or releases the lock to open the door 4 from the body 2 by a small amount. In this embodiment, the actuator 18 is assembled inside the door 4 in front of the door 4. The structure of this actuator 18 is shown in FIG.

The electric actuator 18 shown in FIG. 3 has the entire structure formed on the substrate 20, and is completed by covering the substrate 20 with a cover plate (not shown). The electric actuator 18 can be attached to the body 2 side or the door 4 side. If the electric actuator 18 is attached to the body 2 side, the striker 22 shown in FIG. If attached to the door 4 side, the striker 22 is fixed to the body 2 side.

The board 20 of the electric actuator 18 is attached to the bar of the striker 22.
A cut 20a is provided so that 22b can freely enter and leave. Board 20
A pin 24 is fixed to the upper part of the, and a latch 26 is rotatably attached to the pin 24. The latch 26 substantially corresponds to the cut 20a at a predetermined rotation angle position, and the bar 2 of the striker 22 is
2b has a lock groove 28 that can freely move in and out. Latch 26
A support pin 30 is embedded in the pin, and the pin 30 extends slightly toward the front of the page. The cover (not shown) is provided with a groove shown in FIG. 32 in its mounted state, and the pin 30 engages with the groove 32 and can rotate within the range of the groove. A spring 34 is provided in the groove 32 between its one end surface and the support pin 30.
Is inserted in a compressed state. Therefore, the latch 26 is constantly biased in the clockwise direction within the range regulated by the groove 32.

A pin 36 is fixed at a substantially central position of the substrate 20. A latch lever 38 is rotatably attached to the pin 36. A force of a compression spring 40 is applied to the latch lever 38 from below, so that the latch lever 38 is constantly receiving a biasing force in a counterclockwise direction.

The latch lever 38 is provided with a latch surface 38a, while the latch 26 is provided with a latch surface 26a. In the locked state, the latch lever 38 is at the position shown by the chain double-dashed line, and the latch surfaces 26a and 38a contact each other to prohibit clockwise rotation of the latch 26. Therefore, the striker 22 is prohibited from moving leftward from the electric actuator 18, and the door 4 is locked with respect to the body 2 in the closed position.

A rack 42 is attached to the latch lever 38 via a pin 44. A DC motor 46 is attached to the lower portion of the board 20, and a pinion 50 is fixed to the output shaft 48. The pinion 50 meshes with the rack 42. Therefore, the DC motor
When the 46 is driven, the rack 42 is driven by the rack-pinion mechanism.
Is slid downward, and the latch lever 38 is also pulled down accordingly.

When the latch lever 38 is pulled down, the latch 26 and the latch surfaces 26a and 38a of the latch lever 38 are disengaged, and the latch 26 becomes rotatable. A weather strip for waterproofing, soundproofing, etc. is interposed between the body 2 and the door 4 in a closed position in a compressed state, and a force in the door opening direction is constantly applied to the door 4. That is, the striker 22 is constantly applied with a force to move leftward from the electric actuator 18 in the drawing. Therefore, when the latch 26 becomes rotatable,
The striker 22 moves to the left in the drawing while rotating the latch 26 clockwise. As a result, the door 4 is opened by a minute amount until the elastic reaction force of the weather strip is not received from the body 2.

When the door 4 is closed in the above mechanism, the striker
22 fits in the notch 20a of the board 20 and the locking groove 28 of the rack 26, and further rotates the latch 26 counterclockwise. In this state, the latch 26 and the latch lever 38 are again engaged with the latch surfaces 26a and 38a to realize the locked state.

When a small amount of the slide door is opened by the action of the electric actuator 18 or by a normal operation in an ordinary vehicle not equipped with the electric actuator, the slide button of the courtesy switch 16 fixed to the body 2 side is displaced. To turn the output on.

In FIG. 1, 54 is a door open prohibition switch provided around the driver's seat, 56 is an open switch attached to the outside of the slide door 4, and 58 is an open switch attached to the inside of the slide door 4. These are connected as shown in FIG.

As can be seen in FIG. 5, a battery open inhibit switch 54 is connected in series with the battery. The outside open switch 56 and the DC motor 46 of the electric actuator 18 are connected in series to the door open prohibition switch 54, and further, between the door open prohibition switch 54 and the DC motor 46,
The inner open switch 58 is connected in parallel to the outer open switch 56. Door open prohibition switch 54
Further, a courtesy switch 16, a stop device 60 described later, and an electric motor 10 for opening a door are connected in series.

Next, the operation of this device will be described. Now when the door open prohibition switch 54 is set to off, the open switch
The DC motor 46 is not energized by operating either 56 or 58, and the door 4 is not opened.

Next, with the sliding door 4 closed, the door open prohibition switch 54 is turned on, and then the open switch inside and outside
When either 56 or 58 is turned on, the motor 46 is energized and the electric actuator 18 operates. As a result, the door 4 is pressed by a weather strip or the like to open a minute amount. Then the courtesy switch 16 turns on,
The electric motor 10 for full opening operates, and the slide door 4 is moved in the opening direction by the pinion 12 and the rack 8. In this case, the full-open electric motor 10 is connected in series with the stop device 60, and this device causes the motor 10 to move.
Operates until it is fully opened, and the motor 10
Will stop operating. Although not shown in the figure, the stop device 60 is provided with, for example, a timer circuit or a switch for detecting that the door 4 is fully opened.
A well-known electric device such as a circuit for cutting off the current to the motor or a circuit for stopping energization by detecting that the load torque applied to the motor 10 increases and the current value becomes a certain value or more is operated.

When the sliding door 4 is closed, the electric motor 10 may be rotated in the reverse direction to automatically slide in the closing direction, or manually closed. In this embodiment, since the door 4 is slightly opened by driving the DC motor 46, the opening operation of the open switch 56 or
It is enough to turn on 58, and the door 4 is fully opened by the electric motor 10 after the door is slightly opened, so the operation of opening the door is extremely convenient.

(Effect of the Invention) As described above, according to the present invention, since the door automatically slides from the time when the door is opened by a small amount until the door is fully opened, both hands are closed and the door is pulled to slide. Even when it is not possible, even if it is a small amount, it can be fully opened automatically after that. For this reason, it can be said that the invention is excellent in practicality because the sliding door can be easily fully opened even by weak people such as old people and children.
