Description

  The present invention relates to a vehicle sunroof apparatus having a deflector that tilts in accordance with forward and backward movement of a movable panel.

Many sunroof devices that open and close the opening of the roof of a vehicle are provided with a movable panel along with a deflector that suppresses wind noise and wind intrusion into the passenger compartment. In general, a deflector that has received the urging force of a spring such as a leaf spring has a use position in which the front part is raised in front of the opening according to the movement of the movable panel, and a storage position along the base of the opening. These two positions are selectively taken.
The sunroof device has a movable panel that opens and closes an opening, and the movable panel is supported by a link bracket that is slidable along guide rails on both sides of the opening. The link bracket is slid along the guide rail by an electric motor and a toothed cable, whereby the movable panel moves forward and backward to open and close the roof opening.

  The movable panel has a pair of spaced shoes on its front part. According to the movement of the movable panel, the front shoe starts to push the deflector downward, and the rear shoe lowers the deflector in the middle. And hold it in the retracted position against the urging force of the leaf spring.

The above-described deflector according to the prior art has an advantage that there is no interference with the seal portion of the leading edge of the movable panel and that the deflector can have a large standing angle, and the deflector has a high wind slop suppressing effect.
By the way, the movable panel is mounted on the vehicle by the mounting operation of adjusting the position with respect to the opening of the roof and then fixing the movable panel to the link bracket.

In this mounting operation, since it is impossible to adjust the relative positional relationship between the pair of shoes and the deflector of the movable panel, the positional relationship between the deflector and the movable panel, that is, the pair of shoes, varies from vehicle to vehicle. . Such variation creates a change in the amount of deflection angle of the deflector due to the pair of shoes or a state in which one of the pair of shoes does not properly contact the deflector, resulting in resistance when the pair of shoes and the deflector are in contact with each other. The increase causes a change in the operating speed of the movable panel.
Therefore, this invention makes it the subject which should be solved to eliminate the malfunction of the prior art mentioned above.

In order to solve the above-described problems, the present invention basically employs technical means for providing a link bracket with a pushing member for a deflector.
Adopting this technical means, regardless of the relative positional relationship of the movable panel with respect to the deflector, the deflector is swung from the use position to the retracted position by the link bracket, thereby keeping the contact state between the pushing member and the deflector constant. .

  According to the present invention, a movable panel that opens and closes a roof opening of a vehicle, guide rails disposed on both sides of the roof opening, a link bracket that is slidably supported by the guide rail and moves the movable panel forward and backward And a deflector that is tiltably disposed in front of the opening and takes a use position and a storage position according to the forward and backward movement of the movable panel, and the movable panel is supported by adjusting the position relative to the roof opening on the link bracket. In the vehicle sunroof apparatus, there is provided a vehicle sunroof apparatus having a pushing member that is supported on the link bracket side and contacts the deflector at a plurality of portions according to the movement of the movable panel to tilt the deflector from the use position to the storage position. Provided.

  Preferably, a pushing member consists of a plate-shaped object from which a front-end | tip part and a base part become a contact point to a deflector. Further, the pushing member is formed to protrude from the side surface of the link bracket.

  More preferably, it has a block that is slidably supported in the groove of the guide rail and supported by the link bracket, and the pushing member is formed to protrude from the side surface of the block. The pushing member is composed of at least a pair of spaced apart pin bodies provided on the link bracket.

  Since the relative positional relationship between the deflector and the pushing member can always be maintained correctly, when the deflector is swung from the use position to the retracted position according to the forward / backward movement of the movable panel, the pushing member is positioned relative to the roof opening of the movable panel. Regardless of the adjustment, the deflector can be pushed downward with a constant contact with the deflector. As a result, there is no adverse effect on the operating speed of the movable panel. Further, the pushing member comes into contact with the deflector at a plurality of sites and swings the deflector from the use position to the retracted position. As a result, the standing angle at the use position of the deflector can be increased.

Please refer to FIG. A movable panel 3 and a deflector 4 are arranged in the opening 2 of the roof 1 of the vehicle. Guide rails 5 are disposed on both sides of the opening 2, the front shoe 6 and the rear shoe 7 of the link bracket 8 are slidably disposed in the groove of the guide rail 5, and the link bracket 8 is along the guide rail 5. It can be moved forward and backward. The movable panel 3 is held by the link bracket 8.
The link bracket is coupled to a drive device (not shown) via a rear shoe 7 and a toothed belt (not shown) connected to the rear shoe 7.
The movable panel 3 is opened / closed by operating a driving device (not shown).

  The deflector 4 is disposed along the front edge of the opening 2 and integrally includes arm portions 4a extending in the front-rear direction (left-right direction in FIG. 1) at both ends. The deflector 4 is pivotally supported by a pin 4b on the wall of the guide rail 5 at one end of the arm portion 4a, and receives a biasing force of a spring 9 as an example of a biasing means. FIG. 1 shows a state in which the movable panel 3 is partially retracted. In this state, the pushing member 10 provided on the link bracket 8 is separated from the deflector 4, so that it receives the urging force of the spring 9 and frees the deflector 4. The edge rises to suppress wind noise and wind intrusion into the room.

  Please refer to FIG. 1 to FIG. FIG. 3 is a diagram schematically showing FIG. The pushing member 10 is formed of a corrugated plate, and is formed integrally with the link bracket 8 at the base portion 10a so that the tip end portion 10b protrudes forward (leftward in FIG. 3) from the front end of the link bracket 8. The The pushing member 10 comes into contact with the arm portion 4a of the deflector 4 according to the forward and backward movement of the movable panel 3 at the tip portion 10b and the base portion 10a. The spring 9 as the urging means is shown as a leaf spring 9a, and the deflector 4 receives the urging force of the leaf spring 9a and swings from the storage position to the use position. The rise due to the urging force of the leaf spring 9a of the deflector 4 (swing from the storage position to the use position) is regulated by the base portion 10a of the pushing member 10 coming into contact with the arm portion 4a of the deflector 4, thereby The deflector 4 is kept in the storage position. As shown in FIG. 4, a block 12 may be provided instead of the front shoe 6, and the pushing member 10 may be provided on the block 12. The block 12 is slidably arranged in the groove of the guide rail 5 and is connected to the link bracket 8 using a pin 13. Thus, the block 12 moves forward and backward together with the link bracket 8.

  When the movable panel 3 is attached to the link bracket 8, the movable panel 3 is attached to the link bracket 8 while adjusting the position with respect to the opening 2. The relative positional relationship between the deflector 4 and the link bracket 8 is maintained at an appropriate position by being attached to each guide rail 5. Therefore, by providing the pressing member 10 in the link bracket 8, the relative positional relationship between the pressing member 10 and the deflector 4 is not affected by the position adjustment with respect to the opening 2 of the movable panel 3.

Please refer to FIG. When the movable panel 3 moves forward to close the opening 2 (left side in FIG. 3), that is, when the link bracket 8 moves forward, first, the distal end portion 10b of the pushing member 10 and the deflector 4 come into contact with each other and the distal end portion 10b is used. The deflector 4 at the position starts to be pushed toward the storage position (solid line position shown in FIG. 3). As the movable panel 3 advances, the contact point between the pushing member 10 and the deflector 4 moves forward. Eventually, the root portion 10a of the pushing member 10 comes into contact with the deflector 4 instead of the tip portion 10b. 10a pushes the deflector 4 toward the storage position (the two-dot chain line position in FIG. 3). When the movable panel 3 further advances and the movable panel 3 completely closes the opening 2, the root portion 10 a positions the deflector 4 in the retracted position (the one-dot chain line position in FIG. 3).
When the movable panel 3 moves backward to open the opening 2 (right side in FIG. 3), the contact point between the deflector 4 and the pushing member 10 moves from the root portion 10a to the tip portion 10b. As a result, the deflector 4 rises upon receiving the urging force of the leaf spring 9a and enters the use position. In other words, it can be said that the standing angle of the deflector 4 at the use position is determined at the contact portion of the distal end portion 10b of the pushing member 10 with respect to the deflector 4.

The example shown in FIG. 5 is an example in which the pin bodies 11 a and 11 b as push members are separated from the front side surface of the link bracket 8 and the upper and lower positions are shifted. In the illustrated example, pins are planted on the link bracket 8, but the pin bodies 11 a and 11 b may be protrusions integrally formed with the link bracket 8.
In the retracted state shown in FIG. 5, the rear pin body 11a contacts the deflector 4, and the deflector 4 is kept in the retracted state against the urging force of the leaf spring 9a as the urging means. When the movable panel 3 moves forward so that the movable panel 3 closes the opening 2, the front pin body 11 b starts to push the movable panel 3 toward the storage position by contacting the deflector 4, and then performs this pushing operation. Delivered to the rear pin body 11a.
As shown in FIG. 6, another pin body 11c may be provided between the pin bodies 11a and 11b. The use of the three pin bodies 11a, 11b, and 11c enables a smoother pushing operation of the deflector 4 than the use of the two pin bodies 11a and 11b.

  As an example of illustration, the pushing members 10, 11 a, and 11 b are plate-like bodies or pin bodies, but other shapes may be used as long as they are attached to the link bracket 8.
