The switching rocking lever 73 has a drum brake section 77 at its one end. By pressing the drum brake section 77 against the winding drum section 69 by rocking the switching rocking lever 73, the rotation of the winding drum section 69 can be controlled.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an output switching type door actuator capable of switching the output of a power window motor between a power window and a door automatic closure.

[0002]

2. Description of the Related Art A door of a vehicle is provided with a latch device which cooperates with a striker on the vehicle body side to lock the door in a closed state. As is well known, a certain amount of pressing force is required to bring the door into the fully latched state, and the inertial weight of the door is usually used to obtain this pressing force. However, if the rotation speed of the door in the closing direction is too fast, an unpleasant noise is generated, and if it is too slow, an incomplete latch state, that is, a so-called half-door state occurs.

In a door lock device which solves such a problem, when the latch comes into contact with the striker and slightly rotates when the door is closed, the power window motor is used as a power source to force the latch to move in the complete latch direction. The thing described in Japanese Utility Model Publication No. 5-523, which is adapted to rotate, is shown in FIGS.
It will be described based on. FIG. 15 is a front view of a front door of a vehicle provided with a conventional door lock device, and FIG. 16 is FIG.
17 is an enlarged view of the actuator used in the door lock device of FIG. 15, and FIG. 18 is a view of FIG. 17B.
FIG. Front door 1 of vehicle shown in FIG.
A latch device 3 is disposed in the portion (a), and a reversible motor 7 for a power window that raises and lowers the window glass 5 is disposed in the portion (b).

As shown in FIG. 16, the latch device 3 includes a latch 11 that locks the door 1 in the closed position in cooperation with a striker 9 fixed to the vehicle body. One end of a first link 13 is pivotally attached to the latch 11, and the other end of the first link 13 is pivotally supported at one end by a casing 15.
7 is pivotally attached to the other end. A cable 19 is connected to the other end of the second link 17, and the cable 19 is stretched through the pulley 21 inside the door 1 toward the front side of the vehicle body.

As shown in FIG. 17, a reversible motor 7 for a power window is arranged at a front portion of the door 1 and a worm 25 is provided at an output shaft of the reversible motor 7. . The worm 25 meshes with a worm gear 29 spline-connected to one end of the sliding shaft 27. A pinion 31 is fixed on the sliding shaft 27. The sliding shaft 27 is moved by the return spring 35 of the electromagnetic actuator 33 in the normal state, that is, in all other states except for a short time during which the door 1 is rotated to close the door 1.
The pinion 31 is biased to the left side of 7 and meshes with the fan gear 37 of the window glass lifting mechanism. At this time, a gear 39 rotatably provided on the sliding shaft 27
, The friction plate of the clutch 41 moves leftward from the position of FIG. 17 and is separated from the side surface of the gear 39. The gear 39 has a gear 4
3 is always meshed, and the above-mentioned cable 19 is connected to the mounting bracket 45 provided on the outer peripheral portion of the gear 43 (see FIG. 18).

In the door lock device constructed as described above, the actuator 33 is deenergized in all the states except the period for rotating the door 1 to close it, that is, in the normal state.
The sliding shaft 27 has moved leftward from the position shown in FIG. 17, and the pinion 31 is in mesh with the sector gear 37. Therefore, when the reversible motor 7 is driven, the worm 25 rotates the worm gear 29, and the rotation of the worm gear 29 causes the worm gear 29 to rotate.
7, transmitted from the pinion 31 to the fan gear 37. As a result, the window glass 5 is moved up and down.

On the other hand, when the door 1 is gently rotated in the closing direction and the striker 9 contacts the latch 11, the latch 1
16 is closed by a slight rotation of 1, the sliding shaft 27 is displaced to the right by the actuator 33 as shown in FIG. 17, the clutch 41 is brought into contact with the side surface of the gear 39, and the gear 41 is rotated. 39 is connected to the sliding shaft 27, and the meshing between the pinion 31 and the sector gear 37 is released.

When the switch 47 is closed, the reversible motor 7 is driven, and the gear 43 is rotated counterclockwise in FIG. 18 via the worm 25, the worm gear 29, the sliding shaft 27, and the gear 39. The cable 19 is pulled to the left side in FIG. 18 via the mounting bracket 45.
By pulling the cable 19, the latch 11 is rotated counterclockwise via the second link 17 and the first link 13. By this rotation of the latch 11, the striker 9 is pushed into the recess 11a, and the door 1 is completely closed.

According to such a door lock device, the reversible motor 7 for the power window is used as a drive source to drive the latch 11 in the closing direction even when the door 1 is slightly rotated. Therefore, the door 1 can be reliably closed without causing unpleasant noise.

[0010]

However, in the above-described door lock device, since the rotation of the reversible motor 7 is transmitted to the gear 43 by the sliding of the sliding shaft 27, the sliding shaft 27 and the clutch 41 are transmitted. Actuator 3 for sliding
3 is newly needed. Further, since the sliding shaft 27 having a plurality of gears has to be slid, there is a drawback that the device becomes complicated and large-scale. Further, in the above door lock device, when the latch 11 is forcedly rotated,
The sliding shaft 27 is slid to the right in FIG. 17 by the actuator 33, and the engagement between the pinion 31 and the sector gear 37 is released, so that the disengaged sector gear 37 becomes idle, and as a result, the window is rotated. There is a problem that the glass elevating mechanism reverses due to the weight of the wind glass 5 and the wind glass 5 descends. The present invention has been made in view of the above circumstances, without adding an actuator or the like,
An existing drive source can be used to add an auto-closure function, and even if the mesh between the power window motor and the window glass elevating mechanism is broken, the output switching will not cause the window glass to drop. An object of the present invention is to provide a door actuator.

The switching lock rod 73 is provided with a protrusion 79 on the arm portion on the other end side. The protrusion 79 can be fitted into a recess 81 formed on the outer periphery of the carrier 63. A biasing means (not shown) is provided between the vehicle body side and the switching lock rod 73,
This urging means urges the switching lock rod 73 so that the protrusion 79 fits into the recess 81. The switching lock rod 73 is
With the protrusion 79 fitted in the recess 81, the drum brake portion 77 is retracted to a position away from the winding drum portion 69. On the other hand, when the protrusion 79 is pulled out from the recess 81 due to the swing of the switching lock rod 73, the drum brake portion 77 is arranged so as to be in pressure contact with the winding drum portion 69.

A door lock / switching mechanism 83 is provided near the P / W motor 51, and the swinging shaft 8 is provided in the switching mechanism 83.

The swing of 7 transmits the door lock operation to the door lock mechanism 91.

The swing shaft 85 swingably supports a movable frame 93, and the movable frame 93 houses a swinger 87 inside. The movable frame 93 swings the rocker 87 at a predetermined rotation angle. The swing shaft 85 swingably supports a switching arch 95, and the switching arch 95 can be integrally engaged with the movable frame 93 by a lock pin 97 (see FIG. 3). A spring 99 is arranged between the lock pin 97 and the movable frame 93, and the spring 99 biases the lock pin 97 in the direction of engaging the switching arch 95.

Further, the lock pin 97 is provided with a slider 101, and the slider 101 has an inclined surface 101a. The casing 103 of the switching mechanism 83 includes a release wall 105.

The operation of the output switching type door actuator 121 thus constructed will be described with reference to FIGS.
Fig. 4 shows the process of switching the output of the power window motor to the window up / down or door close (A).
It is explanatory drawing shown by- (C). In the normal state shown in FIG. 4A, the switching lock rod 73 inserts the protrusion 79 into the recess 81 of the carrier 63 by the urging force of the urging means. Therefore, when the power window motor 51 is driven in this state, since the carrier 63 is in a fixed state, the planetary gear 59 rotated by the sun gear 57 rotates the internal gear 61, that is, the wire winding drum portion 69. Let As a result, the wire winding drum unit 69 is configured so that the wound wire 71
The wind glass (not shown) is moved up and down by winding up.

On the other hand, when the door lock switching motor 113 is driven and the switching arch 95 is further rotated from the unlocked state, the slider 101 provided on the movable frame 93 is released, as shown in FIG. 3 (A). The lock pin 97 comes into contact with the wall 105 and comes out of the switching arch 95. As a result, the switching arch 95 further rotates, and as shown in FIG.

When is protruded, the other end of the switching lock rod 73 (left side in FIG. 1) rises, and the drum brake part 77 on one end side is brought into pressure contact with the wire winding drum part 69. As a result, the drum brake section 77 restricts the rotation of the wire winding drum section 69.

At the same time, the protrusion 79 retracts from the recess 81 of the carrier 63. This allows carrier 6
3 is in a rotatable state. This state, that is, FIG.
By driving the power window motor 51 in the state of (B), the carrier 63 rotates, and the recess 81 separates from the protrusion 79, as shown in FIG. 4C. The protrusion 79 displaced from the concave portion 81 contacts the outer periphery of the carrier 63, and holds the switching lock rod 73 in a fixed state by the wire winding drum portion 69.

Therefore, in this state, even if the switching arch 95 is returned by the urging force of the spring 107, the switching lock rod 73 can hold the wire winding drum portion 69 in a fixed state. By driving the power window motor 51 in this state (the state shown in FIG. 4C),
The sun gear 57 causes the planetary gear 59 to roll around the inner periphery of the internal gear 61, and the carrier 63 connected to the planetary gear 59 is rotated to drive the auto-close link 67.

As described above, according to the output switching type door actuator 121 described above, the door lock / switching mechanism 83 is provided.
The output of the power window motor 51 is raised / lowered by the power window and the automatic close link 6
Since it is possible to selectively output to the push and pull of 7, it is possible to add the auto-close function only by using the existing drive source without adding a new actuator or the like.

The planetary gear 59 is provided inside the internal gear 61.
Since the above structure is provided, a compact structure is possible and space saving can be achieved.

Further, since either one of the carrier 63 and the wire winding drum portion 69 can be always locked by the switching lock rod 73, the window glass does not descend even during the automatic closing operation.

Further, since the sun gear 57 meshes with the worm of the power window motor 51 through the worm wheel 55, it is possible to obtain a reverse rotation preventing action by the worm not only during power window output but also during auto close output. You can

Next, a second embodiment of the output switching type door actuator according to the present invention will be described. FIG. 5 is a schematic configuration diagram showing a second embodiment of the output switching type door actuator according to the present invention, and FIG. 6 is a DD arrow view of FIG.
A worm 53 is fixed to a drive shaft of a power window motor (P / W motor) 51, and the worm 53 meshes with a worm wheel 55.

A sun gear 57 is coaxially fixed to the worm wheel 55. The sun gear 57 is the sun gear 5.
It is located at the center of the four planetary gears 59 that mesh with the outer circumference of 7. Each planetary gear 59 meshes with the inner circumference of an annular helical gear / internal gear 131. A right-handed helical gear 131a is formed on the outer periphery of the helical gear / internal gear 131, and the helical gear 131a is a helical gear / internal gear 13
It meshes with a screw gear 133 that rotates around a central axis in a direction orthogonal to the central axis of rotation of No. 1. A female screw 135 is formed on the inner circumference of the screw gear 133, and the female screw 135 is screwed with a screw rod 137 in the central axis direction of the screw gear 133.

Accordingly, the helical gear / internal gear 131 rotates and the screw gear 133 rotates, whereby the screw rod 13 is rotated.
Reference numeral 7 is adapted to move linearly in the direction of the central axis of rotation of the screw gear 133. The linear motion of this screw rod 137 is
It is output as a drive source for auto-close.

Each planetary gear 59 has a rotation center axis fixed to a substantially disk-shaped carrier 139. Therefore, if the rotation of the helical gear / internal gear 131 is restricted, the carrier 139 rotates about the sun gear 57 and the carrier 139 rotates.
If the rotation of the sun gear 57 is restricted, the helical gear and the internal gear 131 will rotate around the sun gear 57. This carrier 1
The wire winding drum portion 141 is fixedly provided on 39,
The wire winding drum portion 141 is wound with a wire 71 for raising and lowering the window glass.

A switching rotary shaft 143 is provided near the helical gear / internal gear 131, and the switching rotary shaft 1 is provided.
A V-shaped brake plate 145 is swingably attached to 43. The brake plate 145 has a first brake portion 147 at one end and a second brake portion 149 at the other end.
The brake plate 145 swings around the switching rotary shaft 143, thereby selectively making pressure contact with the helical gear / internal gear 131 or the carrier 139 and restricting the rotation thereof. .

The coil spring 1 is attached to the switching rotary shaft 143.
51 is arranged, and the coil spring 151 urges the brake plate 145 so that the first brake portion 147 is in pressure contact with the helical gear and internal gear 131. That is, the brake plate 145 normally restricts the rotation of the helical gear / internal gear 131 by the biasing force of the coil spring 151.

In the vicinity of the power window motor 51,
The same door lock / switching mechanism 83 described in the above embodiment is provided. The door lock / switching mechanism 83 is configured to rotate the brake plate 145 via the pressing pin 111 provided at the swing end of the switching arch 95.

The operation of the output switching type door actuator 161 thus constructed will be described with reference to FIG. FIG. 7 shows the process of the switching operation of the switching mechanism shown in FIG.
It is explanatory drawing shown by (B). As shown in FIG. 7A, normally, the brake plate 145 presses the first brake portion 147 to the helical gear / internal gear 131 by the urging force of the coil spring 151, and the helical gear / internal gear 131 is pressed. The rotation of 131 is restricted. Therefore, when the power window motor 51 is driven in this state, the planetary gear 59 rotated by the sun gear 57 is in the fixed state, both the helical gear and the internal gear 131.
The carrier 139 is rotated by rolling on the inner periphery of the carrier.

As a result, the wire winding drum portion 141
(See FIG. 6) rotates, and the wire winding drum portion 141 winds up the wound wire 71, thereby raising and lowering a window glass (not shown). On the other hand, as shown in FIG. 7B, the door lock / switching mechanism 83 is driven to move the switching arch 9
When 5 is further rotated from the unlocked state, the movable frame 93
The slider 101 (see FIG. 3A) provided in the contact portion comes into contact with the release wall 105, and the lock pin 97 comes out of the switching arch 95.

As a result, the switching arch 95 further rotates and presses the pressing pin 111 in the protruding state. Push pin 1
When 11 is projected, the brake plate 145 becomes the coil spring 1
The second brake portion 149 is pressed against the carrier 139 by rotating against the urging force of 51. As a result, the brake plate 1
Reference numeral 45 restricts the rotation of the carrier 139 and releases the restriction of the rotation of the helical gear and the internal gear 131.

In this state, by driving the power window motor 51, the planetary gear 59 rotated by the sun gear 57 rotates the helical gear / internal gear 131, and the helical gear / internal gear 131. The screw gear 133 meshed with the outer periphery of the rotating shaft rotates. By rotating the screw gear 133, the screw rod 137 is moved in the rotation axis direction, and the linear motion of the screw rod 137 drives and operates the auto-close. In the automatic closing drive operation, the door lock switching motor 1 is operated during the automatic closing operation so that the brake plate 145 is continuously locked.
It is necessary to supply an electric current to 13, and during that time, the power window motor 51 is driven to perform an auto-close operation.

According to the output switching type door actuator 161, the output of the power window motor 51 is selectively used for raising and lowering the power window and pushing and pulling the screw rod 137, similarly to the door actuator 121 described above. Since it is possible to output the output, it is possible to add the auto-close function only by using the existing drive source without adding a new actuator or the like.

In this embodiment, since the door closing mechanism section is a module, the option compatibility can be improved. Also, the output shaft 139 in which the output of the power window is fixed to the carrier 139.
Since it can be taken out by a (see FIG. 6), it can be used not only as a wire type as in the conventional case but also as an X arm type power window output. Further, since the brake plate 145 is selectively brought into pressure contact with the carrier 139 or the helical gear / internal gear 131 to restrict the rotation of either one to output the other, locking in a state in which no output is performed Can be ensured. Further, since the screw rod 137 screwed into the screw gear 133 is linearly moved to perform the auto-close operation, the reverse rotation preventing function can be operated not only in the power window but also in the auto-close mechanism.

Next, a third embodiment of the output switching type door actuator according to the present invention will be described. FIG. 8 is a schematic configuration diagram showing a third embodiment of the output switching type door actuator according to the present invention, and FIG. 9 is a view taken along the line EE of FIG. The output switching type door actuator 171 according to this embodiment includes a power window motor 51 and a worm 5.
3, worm wheel 55, sun gear 57, planetary gear 5
9. The helical gear / internal gear 131, the carrier 139, the screw gear 133, and the screw rod 137 are configured in the same manner as the output switching type door actuator 161 according to the above-described second embodiment.

On the other hand, in the present embodiment, the door lock / switching mechanism 173 for switching the outputs of the helical gear / internal gear 131 and the carrier 139 is different from that of the second embodiment. That is, the door lock / switching mechanism 173 is provided with a switching rotary shaft 175,
The switching rotary shaft 175 has a V-shaped brake plate 1 formed in a V shape.
77 is swingably attached. The switching plate 175 is sandwiched between the brake plates 177, and the first brake portion 17
9 and a contact piece 182 is provided on the opposite side of the second brake portion 181, and the brake plate 177 is rotatable by the contact piece 182.

The brake plate 177 is the first brake portion 17

83 is attached, and the coil spring 183 biases the brake plate 177 in a direction in which the second brake portion 181 is pressed against the outer circumference of the helical gear / internal gear 131. Therefore, in the normal state, the brake plate 177 has the helical gear and the internal gear 1
While restricting the rotation of 31, the carrier 139 is rotatable.

The door lock / switching mechanism 173 is provided with a door lock switching motor 113, and the door lock switching motor 113 has a worm 184 fixed to its drive shaft. A worm wheel 185 is meshed with the worm 184, and the worm wheel 185 is coaxial with the pinion 18.
6 is fixed. The pinion 186 meshes with the outer circumference of a rotatable disc (main disc) 187 provided in the door lock / switching mechanism 173. Therefore, the rotation of the door lock switching motor 113 rotates the main disk 187 via the worm wheel 185.

A link 199 is connected to the plate surface of the main disk 187 via a connecting pin 189.
The tip of 99 is connected to a fan-shaped gear 201 for door lock. The door lock fan gear 201 rotates the door lock rotation shaft 203 arranged at the same rotation center. Door lock rotating shaft 203 and door lock fan gear 201
Rotate about the same central axis, but can rotate independently of each other. The door lock fan gear 201 is provided with a coil spring 205. When the coil spring 205 rotates the door lock fan gear 201 by a predetermined angle or more, the coil spring 205 moves the door lock fan gear 201 in a direction opposite to the rotating direction. Work to urge.

Further, a door lock spring (not shown) is provided on the door lock rotation shaft 203, and the door lock spring is provided when the door lock rotation shaft 203 is rotated by a predetermined angle or more. It works to bias the door lock rotation shaft 203 in the rotation direction. Further, the abutting piece 182 described above is arranged on one surface of the main disk 187, and by rotating the main disk 187, the main disk 187 is rotated.
It is adapted to come into contact with the connecting pin 189 provided above.

The door lock is a fan-shaped gear 20 for door lock.
This is performed by rotating 1 to rotate the door lock rotating shaft 203. The door lock turning shaft 203 is provided with a short terminal (not shown), and the short terminal is slidably provided on a sensing pattern substrate (not shown) that outputs a turning position signal of the door lock turning shaft 203. is there. Therefore, the rotation position of the door lock rotation shaft 203, that is, the locked or unlocked state can be electrically detected by these sensing pattern substrates. The door lock switching motor 113 is controlled by a controller in a motor module (not shown) based on the detection signal from the sensing pattern board.

The operation of the output switching type door actuator 171 constructed as above will be described. 10A to 10E are explanatory views showing the process of the switching operation of the switching mechanism shown in FIG. 8 with reference to FIGS. The door lock switching motor 113 is controlled by the controller in the motor module.
The main disk 187 rotated by the door lock switching motor 113 has a door lock at the position (A) in FIG.
It enables neutral output at position (B), unlock at position (C), and switch output at position (E) beyond position (D).

For example, when unlocked, the main disk 187 rotates to the position (C), and the output of the door lock switching motor 113 is shut off by the position signal. On this occasion,
The door lock rotation shaft 203 does not rotate from (A) to (B), but rotates from (B) to (C) as shown in the figure.
Although the door lock fan gear 201 returns to the neutral position by the coil spring 205, the door lock rotation shaft 203 rotates to the unlock position by the action of the door lock spring (not shown). The door-locking pivot shaft 203 is also rotated in the same manner from the (C) position to the (B) position, even while the door lock rotating shaft 203 is in the unlocked state at the (C) position to the locked state at the (A) position. It does not move, but rotates between the (B) position and the (A) position.

When switching output is performed, the main disk 187 is rotated from the unlocked state (C) to the position (D) and further to the position (E).
When the (D) position is exceeded, the rotation of the door lock fan gear 201 does not affect the door lock rotation shaft 203,
It will rotate to the (E) position. By rotating the main disk 187 to the (E) position, the connecting pin 18
9 contacts the contact piece 182, the brake plate 177 (see FIG. 8) rotates about the switching rotation shaft 175, presses the first brake portion 179 against the carrier 139, and connects the second brake portion 181. It is separated from the helical gear / internal gear 131.

This completes the switching of the brake plate 177. In this state, that is, when the main disk 187 rotates to the (E) position, the output of the door lock switching motor 113 is shut off by the sensing pattern substrate, but the coupling pin 189 moves to the contact piece 182 by the action of the coil spring 205. The contacted state will be maintained. By driving the power window motor 51 in this state, similarly to the above-described operation, the helical gear / internal gear 131 is rotated, and the operation force of the automatic closing by the screw rod 137 is passed through the screw gear 133. It will be output.

According to the output switching type door actuator 171, the main disk 187 is provided with the connecting pin 189, and the connecting pin 189 is connected to the door lock fan-shaped gear 201 by the link 199.
Is contacted with the contact piece 182 of the brake plate 177 to switch the output, so that the connecting pin 189 is held in contact with the contact piece 182 by using the coil spring 205 of the fan gear 201 for door lock. Therefore, it is not necessary to continue supplying power to the door lock switching motor 113 during the automatic closing output. As a result, the load on the door lock switching motor 113 can be reduced, and the power consumption can be reduced.

Further, the switching mechanism that does not need to supply power during the auto-closed output has a relatively simple structure, that is, the link 199, the main disk 187, and the connecting pin 1.
It can be constituted by 89.

Next, a fourth embodiment of the output switching type door actuator according to the present invention will be described. 11 is a schematic configuration diagram of a door lock / switching mechanism used in a fourth embodiment of an output switching type door actuator according to the present invention, FIG.
2 is a sectional view taken along line F-F in FIG. 11, and FIG. 13 is an explanatory diagram of a cam follower pin for moving the main disk shown in FIG.

The output switching type door actuator according to this embodiment is similar to the power window motor 5 shown in FIG.
1, worm 53, worm wheel 55, sun gear 5
7, the planetary gear 59, the helical gear / internal gear 131, the carrier 139, the screw gear 133, the screw rod 137, the switching rotary shaft 175, the brake plate 177, and the contact piece 182 are used in the above-described third embodiment. The output switching type door actuator 171 is configured in the same manner. Therefore, the configuration of this portion is omitted from the illustration with reference to FIG.

On the other hand, this output switching type door actuator has a door lock / switching mechanism 213 (FIG. 1) which is substantially the same as the door lock / switching mechanism 173 described in the third embodiment.
1) is provided, but this door lock and switching mechanism 2
In order to stop the door lock switching motor 113 at the locked / unlocked position 13, the main disk 187 has the cam groove 215, and the casing 103 has the cam follower pin 21.
7 is provided.

As shown in FIG. 12, the cam follower pin 217 has a guide groove 219 formed in the casing 103.
The base portion 217a is slidably held, and the pin portion 217b protruding from the base portion 217a is inserted into the cam groove 215 formed in the main disk 187. Therefore, by rotating the main disk 187, the cam follower pin 217 causes the guide groove 219 to move to the main disk 187.
It will move in the radial direction of.

The operation of the output switching type door actuator thus constructed will be described with reference to FIGS. 10, 13 and 14. FIG. 14 is an explanatory diagram showing the relative positions of the cam follower pins when the main disk is rotated. The door lock switching motor 113 is controlled by the controller in the motor module. The main disk 187 driven by the door lock switching motor 113 has the door locked at the position (A), the neutral position at the position (B), the unlock position at the position (C), and the position (E) beyond the position (D) in FIG. Switching output at position.

For example, as shown in FIGS. 13 and 14, in the unlocked state, the cam follower pin 217 is
After moving to the (C ′) position, the output of the door lock switching motor 113 is cut off by the cam mechanism and the timer output. On this occasion,
The door lock fan-shaped gear 201 is returned to the (C) position by the coil spring 205 and is controlled by the motor (D) (D ').
Although guided to (B) and returned to the neutral position of the (B) position, the door lock pivot shaft 203 pivots to the unlock position by the action of the door lock spring.

On the other hand, when switching output is performed, the main disk 187 is rotated from the (C) position, which is the unlocked position, to the (E) position via the (D) position by the forward / reverse control of the motor. Move. When the main disk 187 exceeds the (D) position, the door lock fan gear 201
Does not affect the door lock rotating shaft 203. When the main disk 187 rotates to the (E) position, the motor output is cut off by the cam mechanism and the timer output, but the door lock fan-shaped gear 201 maintains the (E) position by the action of the coil spring 205. Then, by rotating the main disk 187 to the (E) position, the connecting pin 189 contacts the contact piece 182, and the brake plate 177 rotates about the switching rotation shaft 175, and the first brake portion 179 is pressed against the carrier 139, and the second brake unit 1
81 is separated from the helical gear / internal gear 131. This completes the switching of the brake plate 177.

In this way, the door lock and switching mechanism 2
In No. 13, at the unlock position, the door lock switching motor 113 can be temporarily stopped by the cam groove 215 and the cam follower pin 217, and the power supply to the door lock switching motor 113 can be interrupted by the conventional timer circuit. Become.

According to the output switching type door actuator described above, as in the third embodiment, it is not necessary to supply a current to the door lock switching motor 113 during the automatic closing output, and the load on the door lock switching motor 113 is reduced. Can be reduced.

Further, in the above-mentioned third embodiment, FIG.
Since the door lock switching motor 113 can rotate even if the unlocked state of the (C) position is exceeded from the neutral state of the (B) position shown in 0, the completion of the unlocking operation is completed by the door lock rotary shaft 203. The controller in the motor module controls the door lock switching motor 113 so that the door lock switching motor 113 can be stopped based on the rotation position signal.
Since the door lock switching motor 113 can be temporarily stopped at the unlocked position by engaging the cam follower pin 217 with the cam follower pin 217, the conventional timer circuit can cut off the power supply to the door lock switching motor 113 and detect the position. The number of parts can be reduced.
