Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for automatically opening and closing a sliding door of a vehicle such as an automobile, and particularly to an operating device thereof.

(Prior Art) As a conventional automatic opening/closing device for a sliding door for a vehicle, there is one disclosed in, for example, Japanese Utility Model Application No. 57-111972.

The present invention relates to an improvement of such an automatic opening/closing device for a sliding door for a vehicle.

(Problems to be Solved by the Invention) In the conventional automatic opening/closing device for a vehicle sliding door as described above, an operating switch for opening and closing the sliding door is usually provided near the driver's seat.

However, since the sliding door is usually located far away from the driver's seat, for example, if the driver wants to carry out luggage inside the car after the car has stopped, he or she cannot open the sliding door automatically by operating a control switch from the driver's seat. This is convenient in that sense, but if the driver exits the vehicle and then re-enters the vehicle through the open sliding door to take luggage out of the vehicle, the driver must close the sliding door manually or close the door once. Return to the driver's seat, activate the door closing switch,
The problem is that the sliding door must be closed automatically, which is inconvenient in any case.

In order to solve these problems, it has been proposed to provide a switch on the outside of the door to automatically close the door (see Japanese Patent Application Laid-Open No. 11943/1983), but such a device Since the operating switch for closing the door is always exposed outside the vehicle, there is a risk that it may be tampered with, or other problems may occur such as rainwater intrusion and electrical leakage.

It is an object of the present invention to solve these problems and also to prevent the danger of a human body or luggage being caught between the sliding door and the vehicle body when the sliding door is closed.

(Means for Solving the Problems) In the present invention, by operating an operating device provided in the vehicle, a motor provided in the vehicle that can rotate in forward and reverse directions is activated, and the sliding door is automatically opened. In an automatic opening/closing device for a sliding door for a vehicle, the main operating device, which includes a door opening switch for opening and closing the sliding door and a door closing switch for closing the sliding door, is installed at an appropriate location in the vehicle. In addition, in addition to the main operating device, there is also a door-side door closing switch for closing the sliding door, and a switch that immediately changes the direction of movement of the sliding door from the closing direction to the opening direction during the closing operation of the sliding door. A sub-operation device equipped with an emergency reverse movement switch when the door is closed for reversing the door is provided on the interior side of the vehicle near the sliding door, and at a position that can be operated from outside the vehicle when the sliding door is opened. It is said that

(Function) In the present invention, the sliding door can be opened automatically by operating the door open switch or door close switch of the main operating device from a position in the vehicle where the main operating device is installed, such as the driver's seat. , can be closed or closed, and a person attempting to exit the vehicle through the sliding door can do so from inside the vehicle or, if the sliding door is open, after exiting the vehicle.
By operating the door-side close switch, the sliding door can be automatically closed, and when the sliding door closes, a person or luggage is almost caught between the sliding door and the vehicle. Sometimes, by suddenly activating the door-closing emergency reverse movement switch, the sliding door, which had been about to close, can be immediately moved in the direction of opening, thereby avoiding a dangerous situation.

(Example) Hereinafter, an example of the present invention will be described based on the accompanying drawings.

1 is a car body, and 2 is a sliding door.

A channel-shaped lower rail 3 is fixed to the lower side of the vehicle body 1 and has a front end slightly curved inward of the vehicle body 1 in the longitudinal direction. A lower roller device 4 is slidably fitted therein.

A channel-shaped waist rail 5 extending in the front-rear direction is fixed to the middle part of the rear side of the vehicle body 1, and within this waist rail 5 is a waist roller device attached to the middle part of the rear end of the sliding door 2. 6 are slidably fitted.

Although not shown, an upper rail is fixed to the upper side of the vehicle body 1 so as to form a vertical pair with the lower rail 3, and an upper roller device attached to the upper inner surface of the sliding door 2 is attached to the upper rail. (not shown) are slidably fitted.

Therefore, in the sliding door 2, the lower roller device 4, the waist roller device 6, and the upper roller device are connected to the lower rail 3 and the waist rail 5, respectively.
By sliding along the upper rail, it comes out slightly outside the vehicle body 1 from the fully closed position X shown by the imaginary line in FIG. It can be opened to the fully open position Y and closed in the opposite direction.

The automatic opening/closing device for a sliding door for a vehicle according to this embodiment consists of four main parts: a door moving device A, an operating device B, a door lock release device C, and a control device D. Details of each part will be explained below. Explain.

Door moving device A This door moving device A is for directly moving the sliding door 2 from the fully closed position X to the fully open position Y, or in the opposite direction. Motor 7 capable of forward and reverse rotation
and a reduction gear device 8 with a built-in electromagnetic clutch.

As shown in FIGS. 1 to 3, the reduction gear 8
The worm wheel 1 has a key 11 coupled to a rotating shaft 10 which is supported in a case 9 and faces in the vertical direction.
2, and a worm 13 that meshes with the worm wheel 12 and is connected to the rotating shaft 7a of the motor 7.

In the annular gap 12a formed from the upper end to the vicinity of the lower end of the worm wheel 12,
A primary coil 14 and a secondary coil 15 fixed to the case 9 are inserted.

A winding drum 16 is fitted around the lower half of the rotating shaft 10 that hangs down from the lower surface of the case 9 so as to be relatively rotatable.
The armature 17 is attached so that it can move relative to the rotating shaft 10 in the axial direction by spline connection, but cannot rotate relative to the winding drum 16.

Teeth 17a and 12b that can mesh with each other are provided on opposing surfaces of the upper surface of the armature 17 and the lower surface of the worm wheel 12, respectively, on a circumference concentric with the rotating shaft 10.

18 is a release plunger for separating the armature 17 from the worm wheel 12;
9 is a tension spring for pulling the armature 17 toward the winding drum 16, and 20 is a cover that covers the winding drum 16.

Thus, the worm wheel 12 becomes the rotor.
An electromagnetic clutch 21 is formed by the primary coil 14 and secondary coil 15, which serve as excitation coils, and the armature 17, and when only the primary coil 14 is energized, a relatively weak force is applied.
When the teeth 17a of the armature 17 and the teeth 12b of the worm wheel 12 are engaged with each other, the rotational force of the motor 7 is transmitted to the winding drum 16, and both the primary coil 14 and the secondary coil 15 are energized. , both teeth 17a, 12b with even stronger force.
are engaged with each other to increase the force transmitted to the winding drum 16.

Two wires 22, 2 are attached to the winding drum 16.
3 is fixed, and both wires 22 and 23 are wound in opposite directions around the outer periphery of the winding drum 16 and then pulled out in the front-back direction.

As shown in FIGS. 4 and 5, the wire 22 pulled out forward from the winding drum 16 is attached to a guide pulley 25 that is pivotally connected to the lower surface of the floor of the vehicle body 1 with a shaft 24 in the vertical direction. After being passed around,
The end of the bracket 26 facing toward the rear is fixed to the rear edge of the front end of the bracket 26 fixed to the sliding door 2, which faces toward the center of the vehicle body 1.

Further, the wire 23 pulled out rearward from the winding drum 16 is connected to a flexible outer tube 27.
After passing through the inside, it is pulled out forward from the hard guide tube 28 fixed to the rear end of the lower rail 3 and facing in the front-rear direction, and after being almost parallel to the lower rail 3,
intersects the wire 22 at the tip of the bracket 26,
The end thereof is locked to the front edge of the distal end of the bracket 26.

A tension spring 29 is stretched between the end of the wire 23 and the bracket 26 to take up slack in the wire 23.

Reference numeral 30 denotes a guide piece that smoothly guides both wires 22 and 23 so that they are always substantially parallel to the lower rail 3 at the bending part 3c between the straight part 3a and the front curved part 3b of the lower rail 3. is fixed to a bracket 31 that hangs down from the lower surface of the floor of the vehicle body 1, and wires 2
By pressing the wires 22 and 23 from the sides, it is possible to take up slack in the wires 22 and 23 due to a change in the length of the wire feeding path due to the curvature of the lower rail 3.

The bracket 26 is a part of the lower roller device 4, and includes a horizontal roller 32 that engages with the lower rail 3 having a downward U-shaped cross section, and a bottom plate 33 supported further below the lower rail 3. A vertical roller 34 rolling thereon is pivotally supported to form a lower roller device 4.

Thus, the two wires 22 and 23 connect the guide pulley 25, the outer tube 27, and the guide tube 2.
8, guide piece 30, etc., the winding drum 16 forms substantially one loop-shaped endless wire, and rotates in one predetermined direction, thereby fully closing the sliding door 2. The sliding door 2 can be opened from position X to fully open position Y, or closed from fully open position Y to fully closed position X by rotating the winding drum 16 in the opposite direction.

In addition, in the following explanation, it is assumed that the motor 7 and the winding drum 16 are used when opening the sliding door 2.
The rotating direction of the wires 22 and 23 and the rotating direction of the wires 22 and 23 are referred to as normal rotation, and the opposite direction thereof is referred to as reverse rotation.

Operating device B The operating device B includes a main operating device B1 provided near the driver's seat of the vehicle body 1, and a main operating device B1 located on the indoor side of the vehicle body 1 near the sliding door 2, and also operated from outside the vehicle when the sliding door 2 is opened. It consists of a sub-operation device B2 provided at a possible position.

The main operating device B1 is a board 3 fixed to the vehicle body 1.
5, by pivoting the operating handle 37 with the shaft 36, the operating handle 37 can be moved from the neutral position where it is almost horizontal to the door-opening operating position where the tip points slightly upward, as shown in FIG. and a closing operation position with the tip facing slightly downward, and the operation handle 37 is biased with an appropriate spring (not shown) so as to always return to the neutral position, and the operation handle 37 is By moving to the door opening operation position, the door opening switch 38 for rotating the motor 7 in the door moving device A in the normal direction is activated, and by moving the operating handle 37 to the door closing operation position, the motor 7 is reversely rotated. The door opening switch 39 is operated.

As shown in Figures 1 and 6, the sub-operation device
B2 consists of a box 40 fixed to the above-mentioned position of the vehicle body, a door opening switch 41 provided on the box 40, and an emergency reverse movement switch 42 when the door is closed.

When the sliding door 2 is in the middle of moving towards the fully closed position, the emergency reverse movement switch 42 can be pressed to move the sliding door 2 from the halfway position to the fully open position. It was designed so that it could be opened until the end.

The operation of each of the above-mentioned switches will be described later together with the control device D.

Door lock release device C The door lock release device C is a door lock release device C that, when the operating handle 37 is moved from the neutral position to the door opening operation position with the sliding door 2 in the fully closed position X, slides the door before reaching the door opening operation position. This is for linking the operating handle 37 and the door lock 43 so as to release the engagement between the known door lock 43 provided on the door 2 and a striker (not shown) provided on the vehicle body 1 side. A vertical shaft 44 is mounted on the lower surface of the floor of the vehicle body 1 near the front end of the vehicle body 3.
a push lever 45 whose intermediate portion is pivotally connected with a
When the sliding door 2 is closed to the fully closed position
A driven lever 48 is provided on the lower surface of the bracket 26 on the side of the sliding door 2 so that the tip thereof can come into contact with the sliding door 2.

The base end of the push lever 45 and the operating handle 37
are connected to each other by a wire 50 inserted through a flexible outer tube 49 so that the push lever 45 can be rotated by a required angle before the operating handle 37 reaches the door opening operating position from the neutral position. ing.

Both ends of the outer tube 49 are fixed to appropriate positions on the vehicle body 1 near the push lever 45 and the operating handle 37, and guide the wire 50.

The driven lever 48 includes a wire 52 that passes through the outer tube 51, and an intermediate lever 54 that is pivotally mounted inside the sliding door 2 with a horizontal shaft 53.
The driven lever 4 is linked to the release lever 43a of the door lock 43 via the rod 55 in turn.
8 is rotated by the pin 46 of the push lever 45 by a required angle, the release lever 43a
can be moved until the door lock 43 and the striker are disengaged.

Note that the wire 52 and the intermediate lever 54 are connected to each other with an appropriate play, and the intermediate lever 54 is rotated by the operation of a central operating mechanism 57 for manual operation connected via a rod 56. When the driven lever 4 is
8 is prevented from being driven.

Since the central operating mechanism 57 is not directly related to the present invention, a detailed description thereof will be omitted.

Thus, the door lock release device C allows the door lock 43 to be released while the operation handle 37 is being moved from the neutral position to the door opening operation position, that is, before the door opening switch 38 is actuated.

Control Device D The control device D is a device for electrically controlling the opening/closing movement of the sliding door 2, and an example of its electric circuit is shown in FIG. 7.

This circuit diagram is a logic circuit diagram using TTL or CMOS logic elements.

Among them, the main elements and circuits are explained: 58 is a fuse, 59 is a main switch,
60 is a full-open stop switch, which is mechanically provided at the rear end of the lower rail 3, as shown in FIG.
When the bracket 2 of the sliding door 2 is reached,
The limit switch is configured to be activated by contacting the limit switch 6.

38 is the above-mentioned door opening switch 38 that is activated when the operation handle 37 is set to the door opening operation position.
is shown electrically.

61 is installed near the driver's seat or in a control box (not shown) that can be adjusted by a maintenance worker, and by turning on this switch, the door open switch 38 is closed momentarily. Then, the sliding door 2 is continuously opened to the fully open position Y, and this switch is turned OFF, so that the motor 7 is activated only when the door opening switch 38 is closed.
rotates in the normal direction to open the sliding door 2. When the operating handle 37 is returned to the neutral position and the door opening switch 38 is opened while the sliding door 2 is moving to open, the motor 37 immediately stops and the sliding door 2 is opened. This is a door-opening mode changeover switch for changing the operating mode of the door-opening switch 38 so that the door-opening switch 2 stops on the spot.

When the door opening mode changeover switch 61 is turned on, a self-holding circuit 62 is provided for self-holding the door opening switch 38 until the sliding door 2 reaches the fully open position Y. ing.

39 is the above-mentioned door closing switch 39 that is activated when the operation handle 37 is set to the door closing operation position.
This is an electrical representation of the door closing switch 39.
The motor 7 rotates in reverse only while the slide door 2 is closed, and the door open switch 3
When the door 9 is opened, the motor 37 is stopped and the sliding door 2 is stopped at that location.

Reference numeral 41 denotes a door-side door closing switch in the above-mentioned sub-operating device B2, and this door-side door closing switch 41
is designed to be self-held by the closing door self-holding circuit 63 until the sliding door 2 reaches the fully closed position X only by closing momentarily.

Therefore, when you take out the luggage inside the car and leave the car, this door close switch 41
The sliding door 2 can be closed while holding the luggage in the hand by momentarily pushing the door while exiting the vehicle or from outside the vehicle.

Note that when the sliding door 2 is closed by the operation of the door-side door-closing switch 41, the sliding door 2 is stopped for a certain period of time in the middle of the operation, as will be described later, and then completely closed. Close to closed position X.

64 is a fully closed stop switch, which is mechanically connected to the lower rail 3 as shown in FIG.
The limit switch is provided at the front end of the sliding door 2 and is actuated by coming into contact with the bracket 26 of the sliding door 2 when the sliding door 2 reaches the fully closed position X.

Reference numeral 65 designates a temporary stop switch when the door is closed. Mechanically, as shown in FIGS. When the bracket 26 comes into contact with an actuating piece 67 that is pivotally mounted at an intermediate position of the lower rail 3 with a vertical axis 66 during the movement from the position to the fully closed position On the other hand, when the sliding door 2 moves from the fully closed position X to the fully open position Y, the bracket 26
This is a one-way operating switch mechanism that does not operate even if the operating piece 67 comes into contact with the switch.

When this temporary stop switch 65 is closed,
a certain period of time set by the timer circuit 68;
For example, only the motor 7 is temporarily stopped for about one second. In this case, the clutch 21 is in a connected state, and the speed reduction device 8 side and the sliding door 2 are maintained in a connected state, so that even if this temporary stop mechanism is activated when going uphill, for example, the sliding door 2 will not move automatically. There's no turning back.

69 is a torque up switch, which is the fourth
As clearly shown in the figure, the operation is provided at the front part of the lower rail 3 and is rotated by contacting the bracket 26 of the sliding door 2 just before the sliding door 2 reaches the fully closed position X from the fully open position Y side. It is actuated by the arm 70 and serves to energize the secondary coil 15 as well as the primary coil 14 in the clutch 21, thereby increasing the torque of the clutch 21.

Reference numeral 42 denotes the above-mentioned emergency reverse movement switch when closing the door, which is provided on the sub-operation device B2, and is activated when a passenger getting on or off the vehicle is about to be caught while the sliding door 2 is moving in the closing direction. By pressing the button, the rotation direction of the motor 7, which had been in the reverse direction, is immediately reversed to the normal rotation direction, and the sliding door 2 can be returned from halfway to the fully open position Y.

Furthermore, when the main operating device B2 is operated while the sliding door 2 is moving in the opening/closing direction using the door-side door opening switch 41 provided on the sub-operating device B2,
This operation resets the operation of the door-side door-closing switch 41, and the main operating device B1 becomes a control circuit that operates preferentially. If the operator notices this and operates the main operating device B1, the erroneous operation can be avoided.

R1 is a relay for normal rotation of the motor 7;
r1 is the contact, R2 is the relay for reversing the motor 7, r2 is the contact, R3 is the relay for energizing the primary coil 14 in the clutch 21, r3 is the contact, and R4 is the contact for the clutch 21. A relay for energizing the secondary coil 15, r4 is its contact point.

71 is a delay circuit for opening the door, which delays the energization of the relay R1 slightly from the timing of energization of the relay R3, and causes the clutch 21 to operate before the forward rotation of the motor 7; 72, the delay circuit for opening the door; The timing of energization to relay R3 is slightly delayed from the timing of energization to relay R3.
This is a delay circuit for closing the door in order to advance the operation of step 1.

Next, the overall operation and handling of the apparatus of this embodiment will be explained.

When the sliding door 2 is in the fully closed position The switch 41, the full-close stop switch 64, the temporary stop switch 65 when the door is closed, and the emergency reverse movement switch 42 when the door is closed are all open.

The door opening mode selector switch 61 is turned on (ON),
Although it is possible to selectively switch to either OFF, it is assumed that it is set to OFF here.

At this time, which relays R1, R2, R3,
R4 is also not energized, and therefore motor 7 and clutch 21 are also not energized.

In this state, the sliding door 2 can be opened and closed by manual operation in substantially the same manner as in the case of a car without an automatic opening/closing device.

However, in the case of this device, the wires 22 and 23 are forwarded in forward and reverse directions in conjunction with the opening and closing operations of the sliding door 2, and the winding drum 16 is rotated in forward and reverse directions. Since the sliding door 2 is slanted, the sliding door 2 can be opened and closed smoothly.

From this state, turn on the main switch 59,
When the operation handle 37 is rotated to the door opening operation position, the door lock release device C first releases the coupling between the door lock 43 and the striker, and then the door opening switch 38 is closed.

Then, the relay R3 is energized, the contact r3 is closed, the primary coil 14 of the clutch 21 is energized, and after a short delay time, the relay R1 is energized, the contact r1 is closed, and the motor 7 is rotated in the forward direction. ,
The sliding door 2 moves from a fully closed position X to a fully open position Y.

When the sliding door 2 moves slightly toward the fully open position Y from the fully closed position None of the operations affect the operation of the sliding door 2.

At an intermediate position between the fully closed position The temporary stop switch 65 is never activated when the door is closed.

When the operating handle 37 is returned to the neutral position and the door opening switch 38 is opened during the movement of the sliding door 2 from the fully closed position Therefore, the power supply to the relays R1 and R3 is immediately stopped, and the sliding door 2 is stopped on the spot during its movement.

Thereafter, when the operation handle 37 is set to the door opening operation position again and the door opening switch 38 is closed again, the sliding door 2 moves toward the fully open position Y in the same state as before it stopped.

When the door opening mode changeover switch 61 is turned on (ON), even if the door opening switch 38 is opened, the sliding door 2 is self-held by the opening self-holding circuit 62 and the sliding door 2 continues to open. .

When the sliding door 2 reaches the fully open position Y, the fully open stop switch 60 opens and relays R1 and R3
energization is stopped, the motor 7 is stopped, the clutch 21 is released, and the sliding door 2 is stopped at that position.

In this embodiment, the operation of the full-open stop switch 61 is sent as a pulse signal, which acts to switch between energizing and de-energizing the relays R1 and R3. For example, when the sliding door 2 reaches the fully open position Y, Even if the slide door 2 comes into contact with a stopper (not shown), etc., and the fully open stop switch 60 is closed again due to the reaction, the so-called chattering phenomenon will not occur due to the relays R1 and R3 being energized again. It's getting old.

After the sliding door 2 reaches the fully open position Y, when the operating handle 37 is returned to the neutral position, the control device D becomes inactive, and in this state, the sliding door 2 can be freely opened by manual operation, as in the case described above. It can be closed and reopened.

When the operating handle 37 is rotated to the closing door operating position with the sliding door 2 in the fully open position Y and the door closing switch 39 is closed, the relay R3 is energized and the primary coil 14 of the clutch 21 is energized, and then Relay R2 is energized, motor 7 is reversed, and sliding door 2 begins to move toward fully closed position X.

When the sliding door 2 leaves the fully open position Y, the fully open stop switch 60 closes, but the movement of the sliding door 2 is not affected.

When the sliding door 2 reaches an intermediate position from the fully open position Y to the fully closed position The energization to relay R2 is stopped for a certain amount of time, and the sliding door 2 is stopped midway during that time.

During this time, if there are human bodies or luggage of passengers getting on or off in front of the sliding door 2, remove them or
Alternatively, the emergency reverse movement switch 42 can be pressed when the door is closed.

After the above-mentioned certain period of time has elapsed, the relay R2 is energized again, and the sliding door 2 returns to the fully closed position X.
be moved towards.

Note that when the operating handle 37 is returned to the neutral position and the door opening switch 39 is opened while the sliding door 2 is moving toward the fully closed position X direction, the relay R is activated.
2, the power supply to R3 is stopped, the sliding door 2 stops on the spot, and when the door open switch 39 is closed again, the relay R2, R3 is energized, and the sliding door 2 moves toward the fully closed position X. continue.

In addition, while the sliding door 2 is moving toward the fully closed position X direction, the door closing emergency reverse movement switch 42 is activated.
When closed, relay R2 is de-energized, and conversely relay R1 is energized, causing motor 7 to rotate forward.
The sliding door 2 has an emergency reverse movement switch 4 when the door is closed.
From the moment 2 is pressed, it is moved toward the fully open position Y.

While the sliding door 2 is moving toward the fully closed position X, when it reaches the position just before the fully closed position X,
The bracket 26 comes into contact with the actuating piece 70, and the actuating piece 70 closes the torque up switch 69.

Then, relay R2, which had been energized until then,
In addition to R3, relay R4 is also energized, and both the primary coil 14 and the secondary coil 15 of the clutch 21 are energized, and the strong meshing force causes the motor 7 to be energized.
can be transmitted to the winding drum 16, and the sliding door 2 can be moved to the fully closed position It can be moved powerfully.

When the sliding door 2 reaches the fully closed position is separated, and the sliding door 2 stops at that position.

The operation of the full-close stop switch 64 is sent as a pulse signal, similar to the operation of the full-open stop switch 60, and does not cause any chattering phenomenon due to the slight backward movement of the sliding door 2.

When the operating handle 37 is returned to the neutral position after the sliding door 2 reaches the fully closed position It can be opened and closed again.

Note that the above closing operation of the sliding door 2 is performed when the door closing switch 39 is closed, but when the door closing switch 41 is closed, this door closing operation is performed during the closing movement of the sliding door 2. Even if you take your hand off the switch 41, the sliding door 2 is self-held by the door-closing self-holding circuit 63, so the sliding door 2 does not stop mid-movement (in the case of a temporary stop due to the operation of the door-closing pause switch 65, (except when the emergency reverse movement switch 42 is activated), it continues to move toward the fully closed position X.

(Effects of the Invention) Since the present invention has the above configuration and operates as described above, it can produce the following effects.

For example, if the driver wants to pick out the luggage inside the vehicle after stopping the vehicle, by operating the door opening switch on the main control device from the driver's seat, the sliding door will automatically open, and then the driver can exit the vehicle. Go out to
Automatically close the sliding door by re-entering the vehicle through the open sliding door, grabbing luggage, and exiting the vehicle, or by activating the door-side door close switch of the sub-operation device after exiting the vehicle. In some cases, the sliding door can be closed even while carrying luggage.

Therefore, when taking luggage out of the car, it is no longer necessary to put the luggage on the ground, manually close the sliding door, return to the driver's seat, and operate the door close switch. It is extremely convenient.

In addition, in the present invention, since the sub-operation device is installed inside the vehicle near the sliding door 2, when the sliding door is closed, the door-side door closing switch or the emergency reverse movement switch when closing the door can be tampered with from outside the vehicle. This has the advantage that there is no risk of leakage, and there is no risk of electrical leakage due to rainwater.

Furthermore, according to the present invention, an emergency reverse movement switch when the door is closed is provided near the sliding door, so that if a human body or luggage is about to be caught between the sliding door and the vehicle, By activating this emergency reverse movement switch when the door is closed, the sliding door can be opened from the middle, thereby preventing the above-mentioned jamming accident and the like, which has the advantage of being safe.

In addition, sliding doors, which were difficult for people with weak strength such as the elderly and children to close manually,
This is very convenient because the door can be easily closed by simply operating the door-side door close switch provided on the vehicle body near the entrance/exit after boarding or exiting the vehicle.
