Description

  The present invention relates to a sunroof device.

2. Description of the Related Art Conventionally, a sunroof device is known that performs an opening / closing operation of a roof opening by, for example, rotating a movable panel (see, for example, Patent Document 1).
The sunroof device of Patent Document 1 includes an annular belt in a substantially annular guide passage provided in a housing attached to a vehicle roof. A substantially semicircular movable panel is attached to the belt, and the movable panel rotates when the belt is driven along the guide path by the rotational driving force of the motor.

Japanese Patent Laid-Open No. 61-119421

  By the way, in the sunroof apparatus as described above, the semicircular movable panel is rotated by driving the annular belt along the guide passage of the housing, and the opening / closing operation of the roof opening is performed. However, since the movable panel is rotated using the belt, the rotational driving force of the motor is lost due to the generation of sliding resistance due to the sliding of the belt with the housing (guide passage) or the deflection of the belt. This hinders the rotation of the movable panel.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a sunroof device that can rotate a movable panel more suitably.

  A sunroof device that solves the above problems includes a semicircular movable panel that opens and closes an opening formed in a roof of a vehicle, an annular guide rail provided in the opening, and the movable panel along the guide rail. A rotation driving unit that generates a driving force to be rotated; and a link mechanism that is connected to an output shaft of the rotation driving unit and transmits the driving force of the rotation driving unit to the movable panel. The output shaft is positioned at the rotation center of the movable panel, and the link mechanism is drivingly connected to the movable panel from the rotation center side.

  According to this configuration, the link mechanism that transmits the driving force to the movable panel by the rotation driving unit is located at the center of rotation than the movable panel. That is, since the driving force of the rotational drive unit can be transmitted without providing a belt on the outer peripheral side of the movable panel as in the prior art, the movable panel can be suitably rotated while suppressing the loss of the rotational drive force. .

The sunroof apparatus preferably includes a vertical movement mechanism that moves the movable panel in a vertical direction orthogonal to a rotation direction of the movable panel.
According to this configuration, since the vertical movement mechanism that moves the movable panel in the vertical direction orthogonal to the rotational direction of the movable panel is provided, the roof of the vehicle can be avoided, and interference with the roof even if the movable panel is rotated. Can be suppressed.

In the sunroof apparatus, it is preferable that the vertical movement mechanism converts the driving force of the rotation driving unit into vertical movement to move the movable panel in the vertical direction.
According to this configuration, the vertical movement mechanism converts the driving force of the rotary driving unit into vertical movement and moves the movable panel in the vertical direction. Therefore, the vertical movement mechanism moves the movable panel up and down without providing a separate driving unit that generates the driving force. Can be moved.

  In the sunroof apparatus, the vertical movement mechanism includes a rotation restricting portion that restricts rotation of the movable panel accompanying rotation of the output shaft, and a spiral shape that is formed on the outer surface of the output shaft and extends in the axial direction. A groove part, and an engaging protrusion part that is formed in the link mechanism and engages with the groove part, and the engaging protrusion part rotates when the rotation restriction of the movable panel by the rotation restricting part. It is preferable that the movement in the direction is restricted so that the output shaft is moved up and down along with the rotation of the output shaft.

  According to this configuration, since the movement of the engaging projection of the link mechanism is restricted in the turning direction while the turning of the movable panel is restricted by the turning restricting portion, the rotation of the output shaft rotates along the groove. Thus, the engaging protrusion (link mechanism) is moved up and down. As a result, the movable panel can be moved up and down.

  In the sunroof device, it is preferable that when the engagement protrusion is moved by a predetermined amount along the groove, the rotation restriction by the rotation restriction part is released, and the movable panel can be turned.

  According to this configuration, the rotation restriction by the rotation restriction part is released by moving the engagement protrusion part by a predetermined amount along the groove part. That is, when the output shaft is rotated, the engagement protrusion of the link mechanism moves by itself, so that the movable panel can be rotated along with the rotation of the output shaft.

  According to the sunroof apparatus of this invention, a movable panel can be rotated more suitably.

The fitting portion 25 a has a plurality of engaging recesses 25 b that respectively engage with a plurality of extending protrusions 24 c that extend outward in the drive block 24. The block guide 25 is formed to have a substantially C shape in plan view with the front side open.

As shown in FIGS. 3-7, the hinge part 26 is attached to the front-end | tip part of the drive block 24 so that rotation is possible.
As shown in FIG. 7, the hinge portion 26 has two first attachment pieces 26 a so as to sandwich the drive block 24, and can be rotated via a first hinge pin 27 on the proximal end side of the first attachment piece 26 a. Attached to. The front end portion of the first mounting piece 26a has an intermediate portion 26b in which the first mounting pieces 26a are integrated with each other. The intermediate portion 26b is configured to be longer on both sides in the left-right direction (both sides in the vehicle width direction) than the first attachment pieces 26a, and second attachment pieces 26c extending forward from both ends of the intermediate portion 26b are provided. It is done. An attachment piece 13d provided around the notch portion 13c of the movable panel 13 is rotatably attached to the distal end portion of the second attachment piece 26c via the second hinge pin 28.

Further, a hinge holding bracket 30 is attached via a third hinge pin 29 on the front end side of the first attachment piece 26a and in front of the intermediate portion 26b.
The proximal end side of the hinge holding bracket 30 is attached to the distal end portion of the output shaft 23. More specifically, the hinge holding bracket 30 is connected to the flange portion 35a of the fitting pin 35 and the output by fitting the fitting pin 35 into the fitting hole 23b formed in the center of the shaft at the distal end portion of the output shaft 23.

The stopper 32 can tilt around the support shaft 34 supported by the holder 33 in the direction in which the contact surface 32a faces in the rotation direction of the movable panel 13, and the contact surface 32a is a surface. Rotation is restricted on the opposite side to the direction of movement. That is, when the hinge holding bracket 30 rotates with the rotation of the output shaft 23, the rotation is restricted by the stopper 32 in one rotation direction, and the stopper 32 tilts in the other rotation direction to rotate the hinge holding bracket 30. It is designed not to restrict movement.

Next, an operation example of the sunroof device 12 will be described.
In the sunroof device 12 of the present embodiment, the output shaft 23 of the motor 21 is rotated by driving the motor 21. Then, the drive block 24 moves upward or downward along the groove 23a formed on the outer surface of the output shaft 23. More specifically, while the drive block 24 is engaged with the block guide 25 (fitting portion 25a), the rotation of the drive block 24 is restricted, and only the output shaft 23 rotates, and the groove portion 23a. The engaging protrusion 24b of the drive block 24 fitted in the upper and lower parts moves up and down.

  For example, as shown in FIG. 3, when the movable panel 13 is fully closed and the output shaft 23 is rotated in one direction as the motor 21 is driven, the engagement protrusion 24b (drive block 24) is moved upward along the groove 23a. Moving. As a result, the hinge portion 26 tilts around the third hinge pin 29 on the first attachment piece 26a side and on the second attachment piece 26c side downward. Accordingly, as shown in FIG. 4, the rear end side of the movable panel 13 moves downward to enter a tilt-down state.

  As shown in FIG. 4, when the movable panel 13 is tilted down and the output shaft 23 of the motor 21 is further rotated in the same direction, the engagement protrusion 24b moves along the groove 23a, and the drive block 24 is moved by a predetermined amount. It moves upward, the fitting state with the block guide 25 is released, and the drive block 24 can rotate. As a result, the rotation of the output shaft 23 rotates the movable panel 13 via the link mechanism including the drive block 24 and the hinge part 26, and the fully open state as shown in FIG.

  As shown in FIG. 5, when the output shaft 23 of the motor 21 is rotated in the other direction while the movable panel 13 is fully opened, the drive block 24 and the hinge portion 26 are rotated in the other direction. When the wall portion 30a of the hinge holding bracket 30 that holds the hinge portion 26 abuts against the abutment surface 32a of the stopper 32 along with the rotation, further rotation is restricted. Thereafter, when the output shaft 23 is rotated in the same direction, the rotation of the hinge holding bracket 30 is restricted, whereby the rotation of the hinge part 26 and the drive block 24 is restricted. As a result, the engagement protrusion 24b of the drive block 24 moves downward along the groove 23a, the drive block 24 is fitted with the fitting portion 25a of the block guide 25, and the drive block 24 is rotated by the block guide 25. Be regulated.

  Further, when the output shaft 23 is rotated in the other direction as the motor 21 is driven while the movable panel 13 is in the fully closed state, the engagement protrusion 24b (drive block 24) moves downward along the groove 23a. As a result, the hinge portion 26 is tilted downward on the first attachment piece 26a side and on the second attachment piece 26c side about the third hinge pin 29. Accordingly, the rear end side of the movable panel 13 moves upward as shown in FIG.

  Further, in the sunroof device 12 of the present embodiment, for example, when the roof opening 11 is positioned above two seats arranged in parallel in the vehicle width direction, the movable panel 13 is substantially 90 degrees from the fully closed state in one direction. By rotating, the roof opening 11 can be opened only above one of the seats. By further rotating approximately 180 degrees in the same direction from that position (rotating approximately 270 degrees from the fully closed state), the roof opening 11 can be opened only above the other seat.

  In addition, the movable panel 13 of the present embodiment has a semicircular shape in which a notch 13c formed at the center in the vehicle width direction of the rear edge 13b is convex forward, and the front edge 13a of the movable panel 13 is It is a semicircular shape convex forward. That is, since the notch part 13c and the front edge part 13a are similar shapes, a sense of unity is achieved and it is possible to contribute to improvement in design. Moreover, since the front edge part 13a is semicircle shape, generation | occurrence | production of a wind noise at the time of vehicle travel can be suppressed.

  Moreover, the roof opening part 11 is semicircular, and the protrusion part 11b is formed so that it may correspond to the notch part 13c of the movable panel 13. FIG. By adopting such a shape, the longitudinal length of the roof opening 11 is gradually changed in the vehicle width direction, and the occurrence of wind slop can be suppressed. As a result, for example, the wind deflector in front of the roof opening 11 can be omitted. Thus, by omitting the window deflector, it is not necessary to secure a storage space for the window deflector in the roof 10.

As described above, according to the present embodiment, the following effects can be obtained.
(1) The drive block 24 and the hinge part 26 as a link mechanism for transmitting a driving force to the movable panel 13 by the motor 21 (rotation drive part) are positioned at the center of rotation with respect to the movable panel 13. That is, unlike the prior art, the driving force of the motor 21 can be transmitted without providing a belt on the outer peripheral side of the movable panel, so that the movable panel 13 can be suitably rotated while suppressing the loss of the rotational driving force. it can.

  (2) Since the vertical movement mechanism for moving the movable panel 13 in the vertical direction orthogonal to the rotation direction of the movable panel 13 is provided, the roof 10 of the vehicle can be avoided, and even if the movable panel is rotated, the roof 10 Interference can be suppressed.

  (3) Since the driving force of the motor 21 is converted into the vertical movement and the movable panel 13 is moved in the vertical direction, the movable panel 13 can be moved up and down without providing a driving unit for generating a driving force separately.

  (4) While the rotation of the movable panel 13 is restricted by the block guide 25 serving as a turning restricting portion, the engagement protrusion 24b of the drive block 24 that constitutes the link mechanism is restricted from moving in the turning direction. When the rotation of the shaft 23 is rotated, the engagement protrusion 24b (link mechanism) is moved up and down along the groove 23a. As a result, the movable panel 13 can be moved up and down.

  (5) The rotation restriction by the block guide 25 is released by moving the engagement protrusion 24b by a predetermined amount along the groove 23a. That is, when the output shaft 23 is rotated, the engagement protrusion 24b of the predetermined drive block 24 is naturally moved, so that the movable panel 13 can be rotated with the rotation of the output shaft 23.

(6) By eliminating the belt, the guide rail 16 can be thinned.
(7) Since it is not necessary to provide a link mechanism on the guide rail 16 side, the guide rail 16 can be thinned.

(8) Since the sliding resistance can be reduced by eliminating the belt, for example, the detection performance (resolution) of foreign object pinching by the movable panel 13 can be enhanced.
In addition, you may change the said embodiment as follows.

  In the above embodiment, the shade 14 is provided, but an omitted configuration may be adopted. In this case, the shade pressing member 31 and the shade support portion 18 of the guide rail 16 can be omitted.
