Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a safety device for a sliding automatic door.

An automatic door for a vehicle such as a car is a device that automatically opens and closes the vehicle door by operating a door opening/closing operation switch, and uses electricity, pneumatic pressure, hydraulic pressure, etc. as the driving source for opening and closing. This also helps reduce the hassle of opening and closing the door when getting on and off the vehicle. (Refer to Utility Model Publication No. 45-13845.) This also applies to sliding doors that open and close in a sliding manner, especially since they are heavier than swinging doors and require more operating force. In the case of a sliding door such as that described above, it is even more effective in facilitating getting on and off the vehicle as described above.

By the way, some of these sliding doors are equipped with a window that can be opened and closed to improve ventilation on the rear seat side.
Although it is convenient to simply construct such a sliding door so that it can be opened and closed automatically by operating the auto door switch as described above, it poses the following safety problems, and it is necessary to take measures to prevent danger. Measures are needed.

In other words, unlike a swing door, a sliding door is opened and closed by sliding it along the vehicle body, so if a passenger sticks out their fingers, hands, or neck through the openable window like the one above, When the sliding door is opened by operating the door opening switch, there is a risk that the person's fingers, hands, etc. may become caught between the vehicle body and the window sash, etc. Therefore, do not open the sliding door. There is a safety problem when using an automatic door.

This invention was made in view of the above-mentioned problems, and its purpose is to open and close the door opening/closing operation switch when the passenger has his/her finger or hand out from the opening/closing window of the sliding automatic door. It is an object of the present invention to provide safety when opening such a sliding automatic door by preventing an accident such as fingers or the like being caught even when the sliding automatic door is operated to the side.

In order to achieve the above object, the present invention includes a window open state detection switch that detects the open state of a window that can be opened and closed in a sliding door of a vehicle that is opened and closed via a drive device, and controls a door opening circuit. When the window is open, the window open state detection switch is used to open the sliding door by, for example, cutting off the supply of the drive source to the drive device, and then operating the door opening/closing operation switch to the open side. The gist of this is to prevent this.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a side view of an automobile having a sliding automatic door to which the present invention is applied.

In the figure, a sliding door 3 of an automobile 1 is provided with a window 9 that can be opened and closed by two sliding window glasses 5 and 7, and the sliding door 3 can be opened and closed automatically. An automatic door device 11 is provided.

The automatic door device 11 includes, for example, an opening/closing mechanism 15 that connects the sliding door 3 and the vehicle body 13 and opens and closes the sliding door 3 in a sliding manner;
A drive device 17, such as a DC motor capable of forward and reverse rotation, that drives the opening/closing mechanism 15, and a control circuit 19 that rotates the drive device 17 forward or reverse.
In addition to the control circuit 19, the automatic door switch 21 may also be provided, for example, on an instrument panel or the like near the driver's seat.

Further, the sliding door 3 is provided with a window open state detection switch 23 that detects the open state of the window 9 and controls a circuit on the door opening side as shown in FIG. 2, which will be described later. In the case of Fig. 1, since it is a sliding door type, the window opening detection switch 23 is used on one side of the window glass 5.
A first open state detection switch 23a detects an open state caused by rearward movement of the window glass 7, and a second open state detection switch 23b detects an open state caused by forward movement of the other window glass 7. It is being

FIG. 2 is a circuit diagram of an embodiment of the safety device for the sliding automatic door of the present invention, in which the window open state detection switch 23 is connected to the automatic door switch 2.
1 shows an electric circuit diagram when the door opening switch is arranged in electrical series with the contact a of the door opening switch No. 1.

An ignition switch 35 connected to the battery 31 via a fuse 33 is connected to a movable contact c of the auto door switch 21, and has first and second open state detection switches 23a and 23b connected to the door open switch contact a. They are connected in series to the forward rotation terminal 17a of the door drive motor 17, and the door closing switch contact b is connected to the reverse rotation terminal 17b of the door drive motor 17.

The window open state detection switch 23 controls a door-opening side circuit to prevent the sliding automatic door from opening when the above-described openable/closable window of the sliding automatic door is open. In the case of this embodiment, by turning off from the on state, the door opening side circuit between the door opening switch contact a and the door drive motor 17 is cut off, and the power supply from the battery 31 is cut off. At the same time, by connecting the first open state detection switch 23a and the second open state detection switch 23b in series, the window can be opened by either of the two sliding door type window glasses of the sliding automatic door. is open, each of the above open state detection switches 2
When either 3a or 23b is off, the sliding automatic door cannot be opened.

In addition, the door drive motor 1 37 is turned off when the sliding automatic door is fully opened.
On the other hand, the door opening side limit switch 39 stops the door drive motor 17 by turning off when the sliding auto door is fully closed.
This is a limit switch on the door closing side that stops the door closing. Further, 41 is a window open detection switch for the side window, which detects the open state of the side window 27 when the side window 27 shown in FIG. This is for the purpose of detection, and this point will be discussed later.

Next, the operation of the above embodiment will be explained with reference also to FIG.

Now, the ignition switch 35 is on, the sliding door 3 is closed, the window 9 is also closed, and the first and second open state detection switches 23 of the window open state detection switch 23 are turned on.
It is assumed that both a and 23b are on, and the door opening limit switch 37 is also on. It is assumed that the side window 27 is also closed and the window open state detection switch 41 for the side window is also on.

In such a state, the automatic door switch 21 is activated in an attempt to open the sliding door 3.
When the movable contact c of the door open switch is switched to the contact a side, the forward rotation terminal 17 of the door drive motor 17
Power is supplied from the battery 31 to a, and the door drive motor 17 rotates normally. The forward rotation of the door drive motor 17 drives the opening/closing mechanism 15 to open the sliding door 3. When the sliding door 3 is slid backward along the outside panel 25 and fully opened, the opening/closing mechanism 15 is driven. When the door side limit switch 37 is turned off, the door drive motor 17 is turned off.
drive is stopped. In addition, as the sliding door 3 is opened as described above, the closing limit switch 39, which was in the OFF state, is turned on. Therefore, when the sliding door 3 is closed from the open state as described above, , by switching the movable contact c to the door closing switch contact b side.

When window 9 of sliding door 3 is open,
For example, by moving one or both of the two window glasses 5 and 7, the window 9
When the window is open, at least one of the first and second open state detection switches 23a and 23b detects the open state and turns off, so the window open state detection switch 23 is turned off. Therefore, even if the auto door switch 21 is operated,
Since the window open state detection switch 23 is off, power is not supplied to the door drive motor 17, and the sliding door 3 is operated by the door open state detection switch 21.
The door will not open regardless of the operation in step a.

Therefore, when the window 9 is open as described above, even if the passenger sticks out his/her fingers, hands, or neck from the open window 9, the driver may operate the auto door switch 21 without noticing this or by mistake. Even if you do, your fingers will not be pinched. In this way, the automatic opening of the sliding door 3 is operated on the premise that the openable/closable window 9 of the sliding door 3 is closed, and
By not operating the sliding door 3 when it is open, it is possible to prevent an accident in which an occupant's fingers or the like are caught, and it is possible to improve the safety of the sliding door 3 when the door is opened.

In addition, to describe the window open state detection switch 41 for the side window mentioned earlier, as mentioned above, if the side window 27 of the automobile 1 can also be opened/closed, the side window 27
If the sliding door 3 is opened while the passenger is sticking out his/her fingers, etc., there is a risk that the fingers, etc. will be caught between the vehicle body and the sliding door 3 as described above. This is similar to the case of window 9. Therefore, in such a case,
The above-mentioned window open state detection switch 41 for the side window, which is turned on when the side window 27 is closed and turned off when it is open, is also provided on the side window 27, and as shown in FIG. If it is inserted in series in the circuit, when the side window 27 is open, the sliding door 3 will be opened by operating the auto door switch 21.
Since opening of the sliding door 3 can be prevented, the safety when opening the sliding door 3 can be ensured in the same way as described above.

In addition, in the above embodiment, the sliding door 3
A window open state detection switch 23 is turned on when the window 9 is closed and turned off when it is open.
is inserted in series with the drive motor 17, but it can also be provided, for example, between the normal rotation terminal 17a of the door drive motor 17 and the ground. In that case, if two open state detection switches are used as in the above embodiment, the two switches are connected in parallel, and when at least one of them is turned on, the door drive motor 17 is activated. It is sufficient if the short circuit is performed.

In addition, in the above explanation, the sliding door 3
As an example of how to control the door opening circuit in order to prevent the opening of the door, we have taken as an example a case in which the drive device itself is not activated, but the present invention is not limited to this. If a clutch mechanism is built-in, this clutch mechanism can be connected or disconnected in accordance with the operation of the automatic door switch 21.

Furthermore, the present invention can be applied to vehicles in which pneumatic pressure, hydraulic pressure, etc. are used as an opening/closing driving source, and further, the control of the door opening circuit as described above can be applied to vehicles in which microcomputer control is adopted. can also be done using it.

As described above, the present invention detects the open state of a window that can be opened and closed in a sliding door of a vehicle using a window open state detection switch, and when the window is open, drives the sliding door to open it. Regardless of the opening operation of the automatic door switch to activate the device, the door opening circuit is controlled to prevent the sliding door from opening, so that occupants are not able to stick their fingers, hands, or neck out of the window. Even if the door opening operation switch is operated when the door opening operation switch is operated, it is possible to prevent accidents such as fingers or the like from getting caught between the vehicle body and the sliding door, resulting in injury. It has effects such as being able to improve
