Abstract

PROBLEM TO BE SOLVED: To reduce the number of parts, efficiently install a device in a space where the inside of an opening and closing body is limited, adapt the device to an automatic assembly, and improve an assemblability. SOLUTION: Since a driving mechanism unit E and an operating member 15 are arranged on a pushed part 7 side of a latch at an erecting wall part of a base plate 8, the pushed part 7 of the latch and the pushed part of the operating member 15 are on a same surface of the base plate 8, both are not separated, from each other and the distance between both is also near. Therefore, extra such as a transmitting lever are eliminated and the number of parts can be reduced. Moreover, since an extension is not needed for the pushed part 7 of the latch and the pushed moving part of the operating member 15, and it suffices in a minimum size, it is possible to downsize parts, and it is possible to efficiently install a device in a space where the inside of an opening and closing body is limited. In addition, since the driving mechanism unit E and the operating member 15 are arranged on the same surface of the base plate 8, an assemblability can be improved, and it is also possible to adapt the device to automatic assembly.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motor-operated closing device for a motor vehicle in which a driving mechanism is driven by a driving force of a motor to forcibly close a locking device to a fully closed state of the motor.

[0002]

2. Description of the Related Art A conventional electric closing device for an opening / closing body for an automobile,
For example, there is one disclosed in JP-A-10-102865. This device is disposed at the lower end of an automobile opening / closing body whose upper end is pivotally supported by a vehicle body by a support shaft (not shown). The open position completely separates from the striker when the door is opened, and the striker slightly when the door is partially closed. A latch is rotatably supported by a lock device between a half-latch position to be engaged and a full-latch position to completely engage with the striker when the door is completely closed, and an operating member that meshes with a driving mechanism that is operated by a driving force from a motor. The pushing portion pushes the pushed portion of the latch to forcibly rotate the latch from the half latch position to the full latch position.

This locking device has a housing for accommodating a latch and a locking plate which protrude outward from a lower end of an automobile opening / closing body and are pivotally supported inside. A base plate having an L-shaped cross section is provided on the upper surface of the housing, the mounting portion being attached to the upper surface of the housing, and an upright wall portion bent upward from a position deviated in a direction opposite to the striker entry direction with respect to a pushed portion of the latch. A drive mechanism section including a motor is disposed on the side of the upright wall of the base plate on which the latch is pushed by protruding the pinion to the rear side, and an operating member that meshes with the pinion is disposed on the rear side. It is pivotably supported. Since the pushed portion of the latch and the operating member are disposed apart from the base plate, the two transmit the driving force by the transmission lever through the hole formed in the base plate.

[0004]

In the above-mentioned electric closing device for an opening / closing body for an automobile, the drive mechanism portion including the motor and the operating member are disposed separately from and apart from the base plate. And the number of parts increases. If the transmission lever is not set, it is necessary to extend the pushed portion of the latch or the pushed portion of the operating member to a length that can abut against the other party. Will be enlarged. Furthermore, since the drive mechanism and the operating member are disposed separately from and apart from the base plate, during assembly, after assembling one, to assemble the other, the base plate must be turned over. However, it is an obstacle in performing automatic assembly.

SUMMARY OF THE INVENTION In view of the above-mentioned problems of the prior art, the present invention can reduce the number of parts, can be efficiently installed in a limited space inside an opening / closing body, and can be easily assembled in an automatic assembly.
