ABSTRACT:

This application is based on and claims priority under 35 U.S.C. §119 with respect to Japanese Application No. 2001-047616 filed on Feb. 23, 2001, the entire content of which is incorporated herein by reference.
FIELD OF THE INVENTION
This invention generally relates to a motor device for effecting vehicle operation. More particularly, the present invention pertains to a motor device/door closer for actuating a vehicle door operation device for opening and closing a door by operating a latch mechanism for latching the vehicle door by the driving force of a motor device.
BACKGROUND OF THE INVENTION
An example of a known vehicle door closer device is disclosed in Japanese Patent Laid-Open Publication No. H11-303483. Referring to
FIG. 7
, this known door closer device includes a passive lever
75
supported by an active lever
74
of a link mechanism
73
and operatively rotated by rotating the active lever
74
by a motor device
72
. The motor device
72
includes a motor
70
and a reduction gear device
71
. The passive lever
75
rotates a latch
77
of a latch mechanism
76
from a half latched position to a fully latched position. Thus, the half latched door is fully latched by the door closer device. In this case, a cancel lever
78
supported by a base plate along with the active lever
74
contacts the passive lever
75
to restrict the rotation of the passive lever
75
relative to the active lever
74
and thus to rotate the passive lever
75
along with the active lever
74
.
On the other hand, in case the outside door handle is operated for the opening operation during the closing operation of the door closer, as shown in
FIG. 8
, a connecting lever
79
coaxially supported by the cancel lever
78
is rotated to retract the cancel lever
78
from the condition in which the cancel lever
78
restricts the rotation of the passive lever
75
. In this situation, the rotation of the passive lever
75
relative to the active lever
74
is not restricted by the cancel lever
78
, and the rotation of the active lever
74
is in an inactive condition. Simultaneously, a pawl
80
of the latch mechanism
76
is retracted by the rotation of the connecting lever
79
to unlatch the latch mechanism
76
. Accordingly, the door can be manually opened even if the door closer device is under the closing operation.
With the construction of this known vehicle door closer device, the passive lever
75
, the cancel lever
78
, and the connecting lever
79
have to be provided in addition to the active lever
74
for opening the door during the closing operation of the door closer. Thus, the construction of the link mechanism
73
for operating the latch mechanism
76
by the operation of the motor device
72
is relatively complex.
A need thus exists for a motor device for actuating a vehicle door operation device/door closer device which has a more simple construction of the latch operation mechanism for operating the latch mechanism operated by the rotational torque inputted from an electric motor.
SUMMARY OF THE INVENTION
A motor device for actuating a vehicle door operation device includes an output shaft body for outputting a rotational torque of an electric motor, a power transmitting mechanism for transmitting the rotational torque from the electric motor to the output shaft body, and a connection interrupting means for interrupting a power transmission condition between the electric motor and the output shaft body.
According to another aspect, a motor device for actuating a vehicle door operation device includes an output shaft body for outputting a rotational torque of an electric motor, a power transmitting mechanism for transmitting the rotational torque from the electric motor to the output shaft body, connection interrupting means for interrupting a power transmission condition between the electric motor and the output shaft body, a latch mechanism for maintaining the vehicle door at a half open condition or at fully closed condition, and a latch operation mechanism engaged with the latch mechanism for fully closing the half open vehicle door. The motor device transmits the driving force to the latch operation mechanism for operating the latch mechanism for fully closing the half open vehicle door.
According to another aspect, a device for actuating vehicle door operation device includes a motor which produces rotational torque, an output shaft operatively connected to a latch operation mechanism for effecting operation of a latch, a plurality of gears forming a planetary gear mechanism that is operatively associated with the motor for transmitting the rotational torque produced by the motor to the output shaft, and an engagement-disengagement block movable into engagement with one of the gears forming a part of the planetary gear mechanism to fix the one gear against rotation whereupon the rotational torque of the motor is transmitted to the output shaft to operation the latch operation mechanism and movable out of engagement with the one gear forming a part of the planetary gear mechanism to permit rotation of the one gear whereupon the rotational torque of the motor is not transmitted to the output shaft.
