Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device for an automatic door that can be opened and closed manually.

The auto door of a vehicle such as a car is a device that automatically opens and closes the vehicle door by operating an auto door switch, and uses electricity, pneumatic pressure, hydraulic pressure, etc. as the driving source for opening and closing. This 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) By the way, if the door can only be opened and closed automatically by operating the auto door switch as described above, and cannot be done manually, this may be fine for taxis, but for general passenger cars. On the other hand, something like this may be inconvenient. For example, if the person who operates the automatic door is not inside the vehicle and happens to be out of the car, it is inconvenient to have to operate the automatic door all the time. Since it is easy to use, it is desirable to be able to open and close the automatic door manually in the case of a passenger car, etc., from the above-mentioned operational convenience, and automatic door devices that can be opened and closed manually have been proposed.

However, in the case where the door can be opened manually, it is not desirable for safety if the closing operation is completed when the door is in a half-latched state. Although it is easy to recognize when the door is open, it is difficult to notice that the door is slightly ajar.Moreover, unlike a normal door, there is a mechanism to open and close the door automatically as mentioned above. Since it is difficult to create a structure that does not create any resistance when manually operated, the door may end up being relatively ajar compared to a normal door. This means that there is a lot of gender involved.

Therefore, with automatic doors that can be opened and closed manually, if the door ends up ajar as described above, for example, if you drive without noticing this, there is a risk that the door may open while driving. Therefore, it is dangerous and poses a safety problem.

This invention was made in view of the above-mentioned problems, and its purpose is that when the auto door is closed manually, the door is only held in the half-latched state, rather than in the fully-latched state that holds the door in the fully closed position. In order to automatically ensure safety even if the automatic door is closed automatically, the half-latched door will be forcibly closed to the full-latched state, thereby improving safety when the auto door is manually closed. be.

In order to achieve the above object, the present invention provides an automatic door that is automatically opened and closed by an opening/closing device equipped with an automatic door switch, and which can also be opened and closed manually. A door lock latch closure forcibly rotates to a full latch position where the door is completely engaged and held in a fully closed position, and at least a half latch switch for detecting a half latch is provided, and the door is automatically closed. The object of the present invention is to provide a switch circuit that automatically operates the door lock latch closure by the automatic door switch when the door is manually closed, and by the parallel circuit of the automatic door switch when the door is manually closed.

In the figure, auto door switches 113 and 115 are switches that are switched in conjunction with each other, and movable contacts c and c are connected to the anode side and cathode side, respectively, and the door opening switch contacts constituting the door opening switches 113a and 115a. a, a, and door closing switch contacts b, b, which constitute door opening switch contacts 113b, 115b. The door opening switch contact a of the auto door switch 113 on the anode side is connected to one end of the motor 3 via the limit switch 47 and the electromagnetic clutch 11 in the gear box 5.
7 and one end of the electromagnetic clutch 119 in the decelerator 13, and also to the movable contact c of the limit switch 101.

The other end of the electromagnetic clutch 119 is connected to one switching contact _S1 of the limit switch 99 for half-latching detection, and the other end of the electromagnetic clutch 117 is connected to the auto door switch 11.
It is connected to the other switching contact _S2 of the limit switch 99 through a switch 121 which is turned on only when the switch 3 and 115 are switched to the closing switch contacts b and b. The movable contact c of the limit switch 99 and the other end of the motor 3 are connected to the door opening switch contact a of the auto door switch 115 on the cathode side, and one switching contact S ₁ of the limit switch 99 is connected to the auto door switch 115 on the cathode side. The automatic door switch 115 is connected to the door opening switch contact a of the automatic door switch 115 through a switch 123 which is turned on only when the switches 113 and 115 are switched to the door opening switch contacts a and a side.

Further, the door closing switch contact b of the auto door switch 113 on the anode side is connected to the brush 75 of the switch device 77, and the door closing switch contact b,
It is connected to the other end of the above-mentioned motor 3 via a switch 125 that is turned on only when the switch is switched to the b side. Brush 73 of the switch device 77
is connected to the switching contact _S2 of the limit switch 101 mentioned above, and this limit switch 101
Switching contact S ₁ is the auto door switch 1 on the cathode side.
It is connected to the closing switch contact b of No. 15, and
It is connected to a contact 127 that is in constant contact with the first conductor plate 69 of the switch device 77.

Furthermore, a half latch switch 129 is connected to the movable contact c of the auto door switch 113 on the anode side, and is turned on when a half latch is detected in conjunction with the limit switch 99. It is connected to the other end, and is turned on only when the auto door switches 113, 115 are in the neutral position as shown in the figure, and is switched to either the door open switch contacts a, a or the door close switch contacts b, b. switch 131 that turns off when
It is connected to the other end of the above-mentioned motor 3 via. And the auto door switch 115 on the cathode side
A switch 13 interlocked with the switch 131 is connected between the movable contact c and the door closing switch contact b.
3 is connected.

Next, the operation of the above embodiment will be explained with reference also to FIGS. 1 to 3.

Now, the door 1 is in the closed state as shown in FIG. 1, therefore, the switches 99 and 101 are both switched to the switching contact _S2 side, and the switch device 77 is as shown in FIG. Assume that the limit switch 47 is also on.

In order to automatically open door 1 in such a state by operating auto door switches 113 and 115,
The door opening switches 113a and 115a may be operated so as to switch the movable contacts c and c of the automatic door switches 113 and 115 to the door opening switch contacts a and a, respectively. At this time, the switch 123 is turned on in conjunction, so the electrode → door opening switch 113a → limit switch 47 → electromagnetic clutch 119 → switch 123 → door opening switch 11
5a → Due to the closed circuit of the electrode, the electromagnetic clutch 11
9 is energized and excited.

On the other hand, the limit switch 99 is in an operating state since the door 1 is between the half-latched position and the fully closed position, and is switched to the switching contact _S2 side as described above, but since the switch 121 is off, Electromagnetic clutch 117 is not energized.

Then, the motor 3 is operated as follows: electrode → door open switch 113a → limit switch 47 → motor 3 →
The door opening switch 115a is energized by the closed circuit of the electrode. In this way, the electromagnetic clutch 1
19 is excited and the motor 3 is energized, so the opening/closing device A operates as described above.

At the beginning of the operation of this opening/closing device A, sector gear 2
The release lever 107 is released by the protrusion 29 of No. 3, and the door lock 51 is released, and the subsequent rotation of the sector gear 23 pushes out the push rod 37 via the arm 33, and the door 1 opens. Along with this, both switches 101 and 99 are switched to the switching contact _S1 side, and the half latch switch 129 is also turned off.

When door 1 is fully opened, limit switch 47
is turned off, thereby causing the electromagnetic clutch 11
9 is demagnetized, the motor 3 is also stopped, and the door 1 remains open.

In order to automatically close the door 1 from this state, each movable contact c,
The door closing switches 113b and 115b may be operated to switch c to the door closing switches b and b. As a result, switches 121 and 125 are turned on, and switch 123 is turned off. In this case, the limit switch 99 has been switched to the switching contact _S1 side since the door 1 was opened beyond the half-latched position as described above, so the electrode → door closing switch 113b → switch 125 → limit switch 99 → electromagnetic clutch 119→Limit switch 101→Door close switch 115b→
Due to the closed circuit of the electrodes, the electromagnetic clutch 119 is energized and energized, and the motor 3 is energized with the connection relationship of the electrodes being reversed to that in the case of the door opening operation described above, so that the motor 3 rotates in reverse.

Thereby, the door 1 is rotated in the closing direction by the opening/closing device A.

When the door 1 reaches the half-latched position, the limit switch 99 is operated and switched to the switching contact _S2 , the electromagnetic clutch 119 is demagnetized, and the electromagnetic clutch 117 is energized. As a result, the opening/closing device A stops operating, and the door lock clutch closure B starts operating. That is, crank arm 81 begins to rotate and begins to pivot latch 55 toward the fully latched position.

At the same time, the board 67 in the switch device 77 also begins to rotate, for example, counterclockwise in FIG.
The brush 73 comes into contact with the first conductor plate 69, and the brush 75 separates from the second conductor plate 71 and becomes non-contact.
When the door 1 reaches a suitable intermediate position between the half-latched position and the fully closed position, the limit switch 1
01 is activated and switched to the switching contact _S2 side, and as a result, the circuit that had previously reached the electrode from the limit switch 101 via the door closing switch 115b is switched from the limit switch 101 to the brush 7.
3→first conductor plate 69→contact 127→door closing switch 115b→electrode. Therefore, the mechanical operation of the door lock clutch closure B continues, gradually tightening the latch 55 toward the fully latched position.

After the latch 55 reaches the full latch position, when the crank arm 81 and the board 67 complete the second half cycle and return to their original positions, the brush 73 is separated from the first conductive plate 69 and the door close switch 11
The circuit to 5b is cut off, and then the brushes 73 and 75 simultaneously contact the second conductive plate 71 and are short-circuited, causing the motor 3 to suddenly stop. This results in
The entire circuit returns to the closed state shown in FIG. 4 before the above-mentioned opening operation.

Next, assume that door 1 is to be closed manually. That is, auto door switches 113, 11
5 is in the neutral position, therefore switches 131,
133 is on, and limit switch 9
9 and 101 are both switched to the switching contact _S1 side, and the half latch switch 129 is also off.

In this state, manually close and advance door 1.
When reaches the half latch position, the half latch switch 129 is turned on, so the electrode → half latch switch 129 → electromagnetic clutch 117 → limit switch 101 → lock knob switch 13
3 → Due to the closed circuit of the electrode, the electromagnetic clutch 117
is excited in the same way as in the case of automatic closing described above. Simultaneously with this half latch detection, the motor 3 is also energized via the switch 131, and the motor 3 is also reversed in the same manner as in the case of automatic door closing described above. Therefore, the door lock latch closure B starts operating and forcibly rotates the latch 55 from the half-latched position to the full-latched position in the same manner as described above.

Therefore, even if the closing operation of the door 1 is completed in the half-latched state when the door is manually closed, it can be automatically set to the full-latched state, thereby improving safety.

FIG. 5 shows an electric circuit diagram of another embodiment of the present invention, and the same components as those in FIG. 4 are given the same reference numerals and their explanation will be omitted.

In the figure, numerals 135 and 137 are both vehicle speed switches that are turned on when the vehicle is running, and are inserted in the positions of switches 131 and 133 in FIG. 4. According to this configuration, when manually closing the door 1, if the operation of the door 1 is completed at the half-latched position, when the car starts running and the switches 133 and 135 are turned on, the door lock clutch closer B is activated. can be started and automatically fully latched.

In each of the above embodiments, safety can be automatically ensured without requiring any special actions from the occupants.

In each of the embodiments, even when the door is manually closed, the opening/closing device A may be operated at the same time to reliably close the door 1 to the fully latch position in cooperation with the door lock latch closure B. In this case, switch 123 is set to point p in FIGS. 4 and 5.
What is necessary is to insert it between the door opening switch contact a of the automatic door switch 115 and the door opening switch contact a of the automatic door switch 115.

In addition, the drive device of the opening/closing device A and the drive device of the door lock clutch closure B are connected to a common motor 3.
However, it is also possible to use two separate and independent motors.

Furthermore, if the motor 3 is to be suddenly stopped even when the door is manually opened, the switch 125
is a switch configured such that it is on only when the auto door switches 113, 115 are switched to the neutral position and the door closing switch contacts b, b, and is off when the door opening switch contacts are switched to the a, a side. And it is sufficient.

As described above, the present invention provides an automatic door that is automatically opened and closed by an opening/closing device equipped with an automatic door switch, and which can also be opened and closed manually. Provided with a door lock latch closure that forcibly rotates the door to a full latch position that holds the door in a fully closed position, and also has at least a half latch switch for detecting a half latch, and when the door is automatically closed. A switch circuit is provided to automatically operate the door lock clutch closer by the auto door switch when the door is manually closed, and by a parallel circuit of the auto door switch when the door is manually closed. Even if the door is stuck in the half-latched state, the door can be forcibly closed to the fully-latched state by the automatic operation of the door lock clutch closure by the above-mentioned switch circuit. Safety can be ensured automatically without requiring any special actions from the occupants, and safety can be improved when the auto door is closed manually.
