Abstract

(57) [Summary] [Purpose] To open and close the slide door securely with a simple structure using a linear motor. A slide door D that opens and closes the entrance A by being driven by a linear motor 1 arranged along the horizontal opening edge of the entrance A is provided, and the vertical opening edge of the entrance A has an attached motor. A striker 2 is provided which can be reciprocally moved in and out of the vehicle. When the door is closed, the latch piece of the slide door D that has reached the closed end engages with the striker 2 that has been moved to the outside of the vehicle prior to opening the door. At this position, the weather strip B1 around the entrance A is not yet in contact with the door D, and the reaction force due to the deformation is not generated. Therefore, even with the linear motor 1 having a relatively small driving force, the slide door D is surely moved to the closed end position and the striker 2 and the latch piece are engaged with each other. D is completely closed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an opening / closing device for a vehicle sliding door, and more particularly to an opening / closing device capable of surely opening / closing the door with a small driving force.

[0002]

[Prior art]

 Conventionally, as an opening / closing device that automatically opens and closes a vehicle sliding door, there has been one that uses a rotary motor.This is a device that transmits the driving force of the rotary motor to the sliding door by wires, chains, shafts, etc. to open and close it. is there.

On the other hand, in recent years, there has been proposed a linear motor that is used to open and close a slide door (for example, Japanese Utility Model Laid-Open No. 1-79781), which uses a linear motor at the lower edge of the vehicle side entrance / exit. A linear rail having a stator inside is provided in the front-rear direction of the vehicle, and one end of a door panel is connected to a mover moving in the rail to apply opening / closing force to the door.

[0004]

[Problems to be solved by the device]

 By the way, the use of a linear motor can realize simplification of the structure of the switchgear because it does not require a drive force transmission mechanism such as a wire or a clutch mechanism that enables manual opening / closing, but it does not have a reduction mechanism such as a rotary motor. As a result, the driving force generated was relatively small, and it was sometimes difficult to completely close the door against the reaction force of the weather strip, especially when the door was closed.

The present invention solves such a problem, and an object of the present invention is to provide an opening / closing device for a vehicle sliding door that can surely open and close the door with a simple structure using a linear motor.

[0006]

To explain the structure of the present invention, the opening / closing device is a slide which is driven by a linear motor 1 arranged along the horizontal opening edge of a vehicle entrance / exit A to open / close the entrance / exit A. A door D, a striker 2 provided at the vertical opening edge of the entrance / exit A, and reciprocally moved in and out of the vehicle by an attached motor, and a striker 2 provided on the slide door D and attached from the striker 2 by an attached motor. When the latch piece 31 that can be rotated in the disengagement direction and the opening signal from the door opening / closing switch 4 are input, the striker 2 is advanced to the outside of the vehicle, and the latch piece 31 is rotated in the disengagement direction. On the other hand, when the closing signal is input from the door opening / closing switch 4, the sliding door D is closed and the upper end is closed. Detects that the latch piece 31 is engaged, and the striker 2 provided with an open-closing control means 5 for moving room access to the inside of the vehicle.

[0007]

[Action]

 According to the opening / closing device having the above-described structure, when the door is closed, the ratchet piece 31 of the slide door D reaching the closed end is engaged with the striker 2 that is moved to the outside of the vehicle prior to opening the door. Therefore, at this position, the weather strip on the periphery of the entrance / exit A hardly contacts the door D yet, and the reaction force due to the deformation is not generated. Therefore, even with the linear motor 1 having a comparatively small driving force, the slide door D is surely moved to the closed end position and the latch piece 31 is engaged with the striker 2, and then the striker 2 is moved inward and backward in the vehicle. The door D is completely closed by being pressed.

[0008]

【Example】

 In FIG. 1, the slide door D for opening and closing the entrance A is provided with a junction switch 32 at the center of the front end face (right side of the figure). The switch 32 is in a door closed state and is not shown in the figure on the body side. It conducts to the electric wire, detects the full latch of the latch mechanism 3 provided at the center of the rear end of the slide door D, and transmits an operation signal to the built-in motor.

A bracket 62 protruding inward of the vehicle is provided at the lower front end of the sliding door D, and a vertical roller 61 is attached to the tip of the bracket 62 to receive the door load. The stay 63 extends further inward from the tip of the bracket 62, and the mover 11 constituting the linear motor 1 is provided at the tip thereof. The details are shown in FIG.

In FIG. 2, the bracket 62 extends below the step panel A1 of the entrance / exit A toward the inside of the vehicle, and a stay 63 protruding from the tip of the bracket 62 further has a base end of a pair of brackets 64A and 64B by a pin 65. The ends of the brackets 64A and 64B that are joined are opposed to each other vertically. Plate-shaped magnet movers 11A and 11B are fixed to the respective tips, and a rectangular plate-shaped stator 12 around which a coil is wound is located between these movers 11A and 11B.

A large number of stators 12 are provided at equal intervals in a linear rail 13 having a substantially U-shaped cross section and extending in the vehicle front-rear direction along the entrance A. A horizontal roller 66 is attached to the pin 65 and is located in a lower rail 67 provided on the lower surface of the step panel A1. A guide roller 68 is attached to the tip of each bracket 64A, 64B, and the linear rail 13 is attached. It is located in the guide rail 14 provided along the upper and lower opening edges of the. Then, when the coils of the stator 12 are appropriately energized, the movers 11A and 11B move in the linear rail 13, and the bracket 62 opens and closes the slide door D connected to the movers 11A and 11B.

In FIG. 1, a striker 2 with which a latch piece of a door latch mechanism 3 engages is provided at an intermediate position of a rear opening edge of the entrance / exit A, and details thereof are shown in FIG.

In FIG. 3, the striker 2 has a substantially D shape having an opening and projects from the body panel B toward the door. The base portion 21 of the striker 2 is formed in a U shape, and a screw member 22 is installed between both legs, and a worm wheel 23 is connected to the screw member 22. A worm gear 25 of a drive motor 24 (see FIG. 1) provided in a vertical posture meshes with the worm wheel 23. Then, when the motor 24 is operated, the striker 2 moves to the vehicle outer position shown by the chain line in the figure, and the latch piece 31 of the sliding door D (shown by the chain line) which is being closed is engaged with this. In this state, the weather strip B1 provided at the opening edge of the entrance / exit A has not yet come into contact with the door panel D1 and does not receive the reaction force thereof, so that the latch piece 31 and the striker 2 are engaged with each other with a light touch.

In FIG. 1, a controller 5 is installed in a vehicle body B, to which a command signal from an opening / closing switch 4 provided in a driver's seat is input, and the latch mechanism is based on this command signal. The built-in motor 3 and the drive motor 24 of the striker 2 and the stator coil of the linear motor 1 are energized.

A voice monitor 51 is provided above the controller 5 to emit a warning sound when the door is closed.

When a door opening command is issued from the door opening / closing switch 4, the drive motor 24 operates to move the striker 2 out of the vehicle. As the striker 2 moves, the rear end of the slide door D with which the latch piece 31 engages is opened toward the outside of the vehicle. For example, during cold weather, icing is formed between the weather strip B1 at the opening edge of the entrance A and the door panel. Even if there is, the door can be opened easily.

Then, the built-in motor of the latch mechanism 3 is operated to disengage the latch piece 31 from the striker 2, and then the stator coil 12 is energized to linearly move the slide door D rearward of the vehicle by the linear motor 1.

When a door closing command is issued from the door opening / closing switch 4, a warning sound is emitted from the voice monitor 51 and the stator coil 12 of the linear motor 1 is re-energized to move the sliding door D closed. When the front end of the slide door D moves until it comes into contact with the front opening edge of the entrance / exit A, the latch piece 31 engages with the striker 2 that has advanced to the outside position of the vehicle. Moving inward, the slide door D is closed. At this time, the engagement between the striker 2 and the latch piece 31 can be reliably performed even by the linear motor 1 having a relatively small driving force. This will be explained with reference to FIG.

In FIG. 4, when the sliding door D approaches the fully closed position, the weather strip B1 comes into contact with the door panel D1, and the deformation reaction force of the weather strip B1 causes the door closing load to rapidly increase (hatched portion in the figure). Here, in the present invention, the striker 2 and the latch piece 31 are engaged with each other at the point x in the figure where the weather strip B1 is not yet in contact, so that the linear motor 1 having a relatively small driving force can surely perform the engagement operation. Motion is guaranteed. The point y in the figure is for a conventional device in which the striker does not advance, and it is known that a large force is required for the door closing movement due to the deformation reaction force of the weather strip.

When the latch piece 31 is completely engaged, the striker 2 is forced to retract and move inward, and the rear end of the slide door D is pulled inward in the vehicle against the reaction force of the weather strip B1. It will be in a closed state.
