[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a driving device for opening and closing a movable roof panel of a vehicle, for example, a sunroof of a vehicle.

[0002]

2. Description of the Related Art As shown in FIG. 4, a vehicle such as a passenger car has a roof 31 provided with a rectangular opening 32, a movable panel 33 for opening and closing the opening 32, and a sunshade 34. Some have 30.
A frame cover 35 (sunroof frame) is attached to the lower side of the roof 31 at an interval from the roof 31, and an indoor side opening having substantially the same shape is provided at a position facing the opening 32 of the frame cover 35. A portion 36 is formed,
A front opening-shaped storage section 37 is formed by the roof 31 and the frame cover 35 behind the openings 32 and 36, and a pair of left and right guide rails 38 are provided on both left and right sides of the opening 36 of the frame cover 35. Are arranged.

The guide rail 38 has an upper opening 3.
The movable panel 33 made of lighting glass or the like that opens and closes 2
And the sunshade 34 located below the panel 33 to open and close the lower opening 36 are provided slidably in the front-rear direction. A driving device 39 having an electric motor is provided at a front portion of the frame cover 35, and the driving device 39 is interlocked via a flexible cable 40 so as to open and close the panel 33.

Conventionally, as shown in FIG. 5, the drive unit 39 has a motor mounting bracket 41 fixed to a frame cover 35 fixed to the lower surface of a roof 31 by bolts or the like by screws 42 or spot welding, and the like. 41

[0005]

By the way, in the above-mentioned prior art, since the driving device is all mounted on the roof via a metal member, when the motor is started, the vibration of the driving device including the motor causes the mounting bracket and the frame to vibrate. There is a problem that the sound is directly propagated to the cover and resonates to generate noise.

SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and has as its object the purpose of a movable roof panel drive capable of preventing the propagation of vibrations of a drive device due to the start of a motor and preventing the generation of noise. An object of the present invention is to provide a device mounting structure.

[0007]

In the present invention, the following technical measures have been taken in order to achieve the above object. That is, the present invention provides a driving device mounting structure for moving a movable roof panel that opens and closes an opening of a roof in the front-rear direction. In the driving device mounting structure, a driving device mounting opening is provided in a panel support frame, and a mounting bracket is provided at a predetermined interval above the driving device mounting opening. Are supported and fixed via an elastic member, and the driving device is mounted on the lower surface of the bracket from the mounting opening by a fixing means such as a screw.

[0008]

According to the present invention, the mounting bracket is mounted and fixed on the panel supporting frame via the elastic member at an interval, and the driving device is mounted on the mounting bracket so as to be suspended and not in contact with the panel supporting frame. So
Most of the vibration of the driving device due to the motor start is absorbed by the elastic member and does not propagate to the panel support frame,
Therefore, generation of noise can be prevented.

A vehicle body side bracket 2 is fixed to the front side of the opening, and a panel support frame (also referred to as a frame cover), that is, a front sunroof frame 3 is attached to the bracket 2 with bolts 4 and nuts 5.

The front sunroof frame 3 is shown in FIG.
As shown in FIG. 2, a drive device mounting portion 3A is formed at the front end portion of the drive device mounting portion 3A. The drive device mounting portion 3A is provided with a substantially rectangular drive device mounting opening 4. Drive-shaped notch recesses 5 for mounting a drive device are provided at three places, and mounting bolt holes 6 for mounting to the vehicle body side bracket 2 are provided.

Reference numeral 7 denotes a sunroof panel driving device, which comprises a motor 7A and a driving gear mechanism 7B and the like. A mounting seat 9 having a screw insertion hole 8 is provided at three places in a casing of the driving gear mechanism 7B. The mounting screw 10 is inserted from below. Reference numeral 11 denotes a drive unit mounting bracket which is a rectangular plate having a size capable of completely covering the opening 4 and having a similar shape to the opening 4, and a U-shaped mounting corresponding to the cutout recess 5 of the opening 4. Notch holes 12 are provided at three places, and a drive device mounting screw insertion hole 13 and a drive unit mounting hole 14 are provided.
Is screwed into the drive unit 15, and the driving device 7 holds the bracket 11 between the mounting seat 9 and the drive unit 15 while holding the bracket 11 from above and below.
Attached to

Reference numeral 16 denotes an elastic member for mounting the drive device mounting bracket 11 to the sun frame 3.
6 has a vibration damping property and an appropriate hardness made of EPDM (ethylene propylene rubber) and the like, as shown in FIGS. 3 (a) and 3 (b).
As shown in FIG. 3, the annular locking groove 18 in which the cutout recess 5 of the sunroof frame 3 is fitted and locked is provided on the peripheral surface immediately above the flange 17, and a predetermined groove is provided above the groove 18. At an interval S, an annular locking groove 19 into which the notch hole 12 of the mounting bracket 11 is fitted and locked is provided.
