Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle sunroof guide device.

[0002]

2. Description of the Related Art In a vehicle, a lid is slidably attached to an opening of a vehicle body roof so that the lid slides rearward to open the opening, and slides forward to close the opening. The tilt-and-slide sunroof, which allows the rear part of the lid to be tilted up from the closed state, has been widely used.

[0003]

In the tilt-and-slide type sunroof described above, the center of rotation of the lid when tilted up may be mechanically below the lid and slightly behind the front edge of the lid. In many cases, the front edge of the lid moves forward while displacing downward due to tilt-up, and due to this displacement, the weather strip (elastic material such as rubber (Formed to be hollow) bites into the front edge of the opening portion of the roof and is in a crushed state. When the lid rear part is lowered to return to the original fully closed state, the weather strip returns to a state in which it elastically contacts the front edge of the opening with an appropriate compression margin due to the elastic restoring force, but the weather strip due to the tilt down described above. While the excessive crushing is repeated, there is a problem that the elastic restoring force is weakened due to a change with time and the sealing property in the fully closed state is deteriorated.

The present invention aims to address the above-mentioned conventional problems.

[0005]

According to the present invention, in a sunroof device capable of tilting up, a pin fixed to the lid side is fitted and guided at the time of tilting up into a wedge guide for restricting the fully closed position of the lid. Accordingly, a tilt guide groove for displacing the lid backward by a predetermined amount is formed.

[0006]

By forming the tilt guide groove in the wedge guide for restricting the lid fully closed position as described above, the forward displacement of the front edge of the lid caused by tilting up is
It is canceled by the rearward displacement of the lid by the insertion guide of the pin into the tilt guide groove, and excessive compression and crushing of the weather strip at the front edge of the lid is prevented. A good sealing property can be maintained for a long time.

[0007]

, The stopper pin 13 and the tilt guide pin 14
Is displaced downward, the trailing edge of the lid 1 is displaced below the trailing edge of the opening, and the guide roller 51d is notched 22b.
From the above, the rear part of the lid 1 is held in the lowest position after being fitted into the guide groove 21 of the guide rail 2 and thereafter pulled by the rear slide of the drive shoe 4 to form the first link 51 and the second link 52. The lid 1 and the lid 1 slide together backward, and as shown in FIG. 1C, the front slider 3 slides backward on the inclined portion 2a, whereby the front side of the lid 1 is gradually displaced downward and the stopper Pin 13
The tilt guide pin 14 and the tilt guide pin 14 are guided by the guide surfaces 63 and 64 of the wedge guide 6, respectively, and are fitted into the guide groove 21 of the guide rail 2 and slid backward, so that the lid 1
Enters into the lid housing formed on the lower side of the roof behind the opening, and the opening is opened.

When the drive device (not shown) drives in the opposite direction from the open state of the lid 1 and the drive shoe 4 slides forward, the lid 1 is pushed by the drive shoe 4 while keeping the lowermost state and is moved forward. 1C, the stopper pin 13 and the tilt guide pin 14 are below the rear portions of the guide surfaces 63 and 64 of the wedge guide 6 when the front slider 3 reaches the bending position to the inclined portion 2a. The front sliders 3 are located on the respective sides, and the front portion of the lid 1 gradually rises as the front slider 3 moves up the inclined portion 2a, and the stopper pin 13 and the tilt guide pin 14
Is guided by the guide surfaces 63 and 64 of the wedge guide 6, respectively, and is slid forward while being displaced upward.
As shown in (B), the stopper pin 13 has the stopper groove 6
The front movement of the lid 1 is restrained by contacting the stopper surface 61a of the first lid 1. As described above, when the forward movement of the lid 1 is restrained, the front edge portion of the weather strip 1a of the lid 1 is elastically contacted with the front edge portion of the opening with a predetermined compression margin.

From this state, when the drive shoe 4 continues to slide forward, the first link 51 and the second link 52 move forward, and the guide roller 51d causes the cutout portion 2 to move.
While being guided by the guide surface 71 of the wedge member 7 attached to 2b and moving from the guide groove 21 of the guide rail 2 to the upper surface 22, the first link 51 rotates clockwise about the pin 51a, and Accordingly, the second link 52 also rotates counterclockwise about the guide pin 52c to lift the rear portion of the lid 1 upward, and the guide pin 51b moves forward in the rear horizontal portion of the front guide groove 12a. As the guide pin 51c moves forward in the rearward upward slope of the rear guide groove 12b and enters the front horizontal portion, the lid 1 pivots upward about the axial attachment point of the front slider 3, The rear edge portion of the strip 1a is elastically contacted with the rear edge portion of the opening portion at an appropriate compression margin to be in the fully closed state shown in FIG. 1 (A).

When it is desired to tilt up the lid 1 from the fully closed state, the drive shoe 4 is slid further forward by driving the drive device. Then, the first link 51 and the second link
The link 52 moves forward, the guide pin 51b moves forward in the front descending inclined portion of the front guide groove 12a to lift the rear portion of the lid 1 upward, and the guide pin 5

In this case, since the pin 11a, which is the center of rotation of the lid 1, is located in the lower rear part of the front end of the lid 1, the front end edge of the lid 1 is rotated downward due to the tilt-up of the lid 1. Therefore, if the rotation center 11a does not move, the front edge of the weather strip 1a bites into the front edge of the opening and is excessively compressed.

However, according to the present invention, when the lid 1 is tilted up, the tilt guide pin 14 is moved to the wedge guide 6.
By being guided by the tilt guide groove 62 and moving upward, the lid 1 is tilted up and displaced rearward due to the rearward inclination of the tilt guide groove 62, and the shaft pin 11a of the front slider 3 has a predetermined size ( By moving backward by about 2 mm), the forward displacement of the front end edge of the lid due to the tilt-up is canceled out and excessive compression and crushing of the front edge of the weather strip 1a do not occur, and a smooth tilt-up operation is performed. It is a thing.

When the drive shoe 4 slides backward from this tilt-up state, the first link 51 and the second link 5
2 and the guide pin 51b move rearward together, and the guide pin 51b moves rearward along the front descending inclined portion of the front guide groove 12a, whereby the rear portion of the lid 1 is pulled down, and the guide pin 51c moves rearward. It is fitted into the front horizontal portion of 12b and returns to the fully closed state shown in FIG. in this case,
When the lid 1 is moved down, the tilt guide pin 14 and the stopper pin 13 are guided by the tilt guide groove 62 and the stopper groove 61 of the wedge guide 6 to move downward, so that the lid 1 moves when tilted up. The shaft-mounted pin 11a of the front slider 3 is returned to the original position before tilting up by being displaced forward by the amount of rearward displacement.

As described above, a wedge member having a stopper function, which has been conventionally required for restraining the forward movement of the lid 1 at a predetermined position, is used, and a tilt guide groove is formed in the wedge member. With the configuration in which only the tilt guide pin that is fitted and guided in the tilt guide groove is provided,
It is possible to prevent excessive compression and crushing of the front edge portion of the weather strip at the time of tilting up without adding new parts, and to maintain the sealing property of the weather strip for a long period of time.

In the illustrated embodiment, the wedge guide 6 is formed with the stopper groove 61 and the tilt guide groove 62, and the bracket 11 of the lid is fixed with the stopper pin 13 and the tilt guide pin 14, respectively. Although shown, the stopper surface 61 formed on the wedge guide 6
The stopper groove 61 with a is provided with a function as a tilt guide groove as an inclined groove whose upper part is inclined rearward, and the stopper pin 13 fixedly mounted on the bracket 11 is guided by the stopper groove formed by the inclined groove when tilting up. The lid 1 may be displaced rearward by a predetermined amount by moving the lid 1 upward, which can further simplify the structure.

In the above-mentioned embodiment, the drive device usually comprises an electric motor and a speed reducer, the drive wire is operated by the output of the speed reducer, and the drive shoe 4 connected to the drive wire is the guide rail 2. Although it is guided by the guide groove 21 and slides back and forth, this configuration is the same as a conventionally known one, and therefore illustration and detailed description thereof are omitted.
