Description

  The present invention relates to a sunroof device.

  Conventionally, as a sunroof device, what was described, for example in patent documents 1 is known. This sunroof device includes a movable panel (movable closing element) for opening and closing an opening formed in the roof of a vehicle, a pair of guide rails provided to extend in the front and rear direction at both widthwise edges of the vehicle in the opening, And guide means for connecting the front ends of both guide rails in the width direction of the vehicle. Further, the sunroof device comprises an electric motor, a pair of drive cables (flexible drive cables) which are connected to the electric motor and move along the guide rails through the guide means, and slide in the longitudinal direction of the vehicle on both guide rails. And a pair of movable closure supports which are movably supported and which support the widthwise edges of the movable panel. Each movable closing support is connected to each drive cable, and adjusts the movable panel by sliding in the longitudinal direction of the vehicle along the guide rail.

  The guide means are normally used for the drive cable so that the movable closure support and the movable panel can have a limited longitudinal movement, for example when an excessive force is exerted on the drive cable by the movable panel being open at the time of a collision. It is configured to be able to deviate from the predetermined path defined by the guide means in use. In other words, the guide means is provided with an ejectable outlet of the drive cable and a space for receiving the drive cable projecting from the outlet. This is said to be able to absorb the kinetic energy provided by the movable panel at the time of a collision.

  By the way, in patent document 1, when the force which exceeds assumption is applied to a drive cable by the movable panel in an open state at the time of a collision, the drive cable may destroy the above-mentioned exit and space. In this case, the movable closing support may fall off the guide rail and the movable panel may come out of the vehicle.

  An object of the present invention is to provide a sunroof device capable of suppressing the movable panel from coming out of the vehicle at the time of a collision.

  The sunroof device which solves the above-mentioned subject has a metal base panel installed in the peripheral part of the opening formed in the roof of vehicles, and a rail part, and it is back and forth in the width direction both edges of the vehicle of the said base panel. A pair of metal guide rails provided so as to extend in a direction, a pair of sliding members slidably supported by the two guide rails in the longitudinal direction of the vehicle, and the both sliding members, A pair of drive cables for moving the sliding members in the longitudinal direction of the vehicle, and a guide portion which inclines upward toward the rear of the vehicle and communicates with the front end of the rail portion at the rear end A pair of resin guide blocks attached to the two guide rails, and at the front end of the guide portion in the fully closed state of the movable panel for opening and closing the opening, and from the fully closed state to the open state A guide convex portion is provided which passes through the guide portion to reach the rail portion in the transfer state, and a pair of supports which cooperate with the two slide members to support both widthwise edge portions of the movable panel in the width direction It has a bracket and a pair of control walls which are provided on the base panel and cover the upper side of the space formed in the front of the vehicle of the rail portion of both guide rails.

  According to this configuration, when the movable panel is in the open state, the guide convex portions of the both support brackets are positioned on the rail portions of the both guide rails. In this state, when an excessive force is applied to the both drive cables by the movable panel at the time of a collision, the connecting portion between the both drive cables and both sliding members is broken, and both the support brackets serve as the guide convex portion. Along with the movable panel along with the movable panel. Along with this, when the guide convex portion reaches the front end of the rail portion, the guide convex portion enters the space while destroying the guide block. The guide convex portion located in the space is received by the restriction wall located above the guide convex portion. Thereby, even if the both support brackets (guide convex part) fall out of the both guide rails, it can control that a movable panel comes out to the outside of vehicles.

In the above-mentioned sunroof device, preferably, the restriction wall is integrally provided on the base panel.
According to this configuration, the number of parts can be reduced by integrally providing the restriction wall on the base panel.

  The present invention is effective in that the movable panel can be prevented from coming out of the vehicle at the time of a collision.

Hereinafter, one embodiment of a sunroof device will be described. In the following, the front-rear direction of the vehicle will be referred to as "front-rear direction".
As shown in FIG. 1, a substantially square opening 11 is formed in a roof 10 of a vehicle such as a car. The opening 11 has a substantially square frame-shaped peripheral portion 11 a. And the base panel 20 which consists of a metal plate (for example, iron plate) is mounted in the peripheral part 11a. The base panel 20 has a pair of side frames 21, a front frame 22 and a rear frame 23 which extend along the vehicle widthwise side edge, the front edge and the rear edge of the opening 11 respectively, It has the middle frame 24 which connects the front-back direction middle part of the both-sides part frame 21 in the width direction of a vehicle. That is, the base panel 20 has a substantially "day" shaped frame shape including the side frames 21, the front frame 22, the rear frame 23, and the intermediate frame 24. A pair of guide rails 15 is attached to the base panel 20 below the side frames 21. Each guide rail 15 is made of, for example, an extruded material of aluminum alloy, and has a constant cross section in the longitudinal direction and extends in the front-rear direction.

  Further, on the roof 10, a substantially square front panel 12 made of a plate material made of glass or resin, for example, and a center panel 13 and a rear panel 14 as movable panels are juxtaposed in the front-rear direction above the base panel 20. . The front panel 12 and the rear panel 14 are attached so as to always close the front and the rear of the opening 11, respectively. On the other hand, the center panel 13 is attached so as to be able to open and close the middle portion in the front-rear direction of the opening 11. That is, the center panel 13 is mounted in a tilt-up operation in which the rear side portion rises with the front side portion as a fulcrum, a pop-up operation in which both the front side portion and the rear side portion rise, and sliding operation in the front-rear direction. In the opening and closing operation by the center panel 13, a so-called outer sliding type is adopted in which the sliding operation is performed in the pop-up state.

  As shown in FIG. 2, a driving shoe 30 as a sliding member is guided and supported movably in the front-rear direction on each guide rail 15. In addition, an electric drive source 16 such as an electric motor having an output gear is disposed at the front edge of the opening 11. The electric drive source 16 is connected to each of drive belts 17 as a pair of substantially belt-like drive cables made of, for example, a resin material. Both drive belts 17 are connected to both drive shoes 30 to move them simultaneously in the back and forth direction.

  On the other hand, a pair of support brackets 40 are attached to both widthwise edge portions of the center panel 13 in the vehicle width direction. The two support brackets 40 are mainly formed of a metal plate, and support both widthwise edge portions of the center panel 13 in the state of being linked with the two drive shoes 30. The center panel 13 performs the above-described opening and closing operation together with the support brackets 40 as the drive shoes 30 move in the front-rear direction.

  As shown in FIGS. 3 and 4, each guide rail 15 has a substantially U-shaped grooved rail portion 15a that opens in the width direction of the vehicle and communicates in the front-rear direction. At the front end of each guide rail 15, a guide block 50 made of a resin material is attached. The guide block 50 is formed in a substantially triangular prism shape with an inclined surface 51 that inclines upward toward the rear of the vehicle. Along the inclined surface 51, the guide block 50 extends upward toward the rear of the vehicle. The guide part 52 which inclines so that it may go is formed. The guide portion 52 is formed in a substantially U-shaped groove shape opening in the width direction of the vehicle, and communicates with the front end of the rail portion 15a at the rear end.

  On the other hand, the front end portion of each support bracket 40 has a substantially arm-shaped front link portion 41 extending diagonally downward to the front of the vehicle, and is provided at the lower end portion of the front link portion 41 to project in the width direction of the vehicle. It has a guide convex portion 42. The guide convex portion 42 is formed of, for example, a metal material into a substantially cylindrical shape, is movable along the guide portion 52 or the rail portion 15a, and is rotatable around an axis extending in the width direction of the vehicle. Have been inserted into them. The guide convex portion 42 is positioned at the front end of the guide portion 52 in the fully closed state in which the center panel 13 closes the opening 11 and passes through the guide portion 52 in the state of transitioning from the fully closed state to the open state To reach. At this time, the front portion of the support bracket 40 is raised.

  A front check member 45 is interposed between the drive shoe 30 and the front link portion 41. The front check member 45 restricts the movement of the front link portion 41 while the moving distance of the drive shoe 30 from the position when the center panel 13 is in the fully closed state to the rear of the vehicle is a predetermined distance. While allowing only the rotation around the convex portion 42, the movement of the front link portion 41 integral with the drive shoe 30 is permitted when the movement distance exceeds a predetermined distance.

  A rear link 46 is supported on each guide rail 15 at the rear of the vehicle of the front link 41. At the rear end of the rear link portion 46, a slide pin (not shown) is provided so as to protrude in the width direction of the vehicle. The slide pin is inserted into a slide groove (not shown) formed in the support bracket 40 so as to extend in the front-rear direction. Thus, the support bracket 40 is supported by the rear link portion 46 so as to be movable in the front-rear direction on the slide pin and rotatable around an axis extending in the width direction of the vehicle.

  A rear check member 47 is connected to the rear link portion 46. The rear check member 47 is a rear link portion integral with the drive shoe 30 while the distance of movement of the drive shoe 30 to the rear of the vehicle from the position when the center panel 13 is fully closed is up to a predetermined distance. The movement of the rear link portion 46 is restricted while the movement of the rear link portion 46 is permitted while the movement of the rear link portion 46 is permitted. The rear link portion 46 extends in the front-rear direction when the center panel 13 is in the fully closed state, and is configured to raise the rear end while moving integrally with the drive shoe 30 to the rear of the vehicle. ing. At this time, the rear side portion of the support bracket 40 rises.

  Here, as shown in FIGS. 3A and 3B, it is assumed that the center panel 13 is in a fully closed state. At this time, the front link portion 41 is restricted from moving integrally with the drive shoe 30 by the front check member 45, and the rear link portion 46 is allowed to move integrally with the drive shoe 30 by the rear check member 47. ing. Therefore, when the drive shoe 30 moves to the rear of the vehicle in this state, the front link portion 41 (support bracket 40) is rotated around the guide convex portion 42 positioned at the front end of the guide portion 52. The rear end of the ascends. As a result, the center panel 13 supported by the support bracket 40 is tilted up and shifts to the tilt up state.

  Subsequently, it is assumed that the drive shoe 30 further moves to the rear of the vehicle and the movement distance reaches the above-mentioned predetermined distance. At this time, the front link portion 41 is allowed to move integrally with the drive shoe 30 by the front check member 45, and the rear link portion 46 is restricted by the rear check member 47 from moving integrally with the drive shoe 30. Therefore, when the drive shoe 30 further moves to the rear of the vehicle, the guide convex portion 42 ascends along the guide portion 52 while rotating the support bracket 40 around the slide pin of the rear link portion 46 and the rail portion Enter 15a. As a result, the center panel 13 supported by the support bracket 40 pops up and shifts to the pop up state.

  Subsequently, it is assumed that the drive shoe 30 further moves to the rear of the vehicle. At this time, as shown by changes to FIGS. 4A and 4B, the front link portion 41 moves to the rear of the vehicle while moving the guide convex portion 42 along the rail portion 15a. Then, the support bracket 40 moves to the rear of the vehicle while sliding the aforementioned sliding groove on the sliding pin of the rear link portion 46. As a result, the center panel 13 supported by the support bracket 40 is opened in the pop-up state and becomes fully open.

The transition (return) of the center panel 13 in the fully open state to the fully closed state through the tilt-up state is an operation in the reverse order to that described above, and therefore the description thereof is omitted.
As shown in FIGS. 5 and 6, a substantially wedge-shaped restricting wall 25 extending integrally to the rear of the vehicle is integrally provided at the front end of the front frame 22 in the vehicle width direction. The restriction wall 25 covers the upper side of the space S formed in front of the vehicle of the rail portion 15a. That is, the restriction wall 25 covers the upper side of the trajectory L in which the guide convex portion 42 located in the rail portion 15 a jumps out to the front of the vehicle of the rail portion 15 a.

The operation of this embodiment will be described.
When the center panel 13 is in the open state (pop-up state), the guide convex portions 42 of the support brackets 40 are located on the rail portions 15 a of the guide rails 15. In this state, when an excessive force is applied to both drive belts 17 by the center panel 13 at the time of a collision, the connecting portion between both drive belts 17 and both drive shoes 30 is broken and both support brackets 40 serve as guide projections 42 as rail portions 15a. While moving to the front of the vehicle along with the center panel 13 moves to the front of the vehicle. Along with this, as shown in FIG. 6A, when the guide convex portion 42 reaches the front end of the rail portion 15a, the guide convex portion 42 destroys the guide block 50 and along the locus L of the rail portion 15a. Jump out to the front of the vehicle and enter the space S. The guide convex part 42 located in the space S is received by the control wall 25 located above it. Thereby, even if both the support brackets 40 (guide convex part 42) drop | omit of both the guide rails 15, it can suppress that the center panel 13 comes out to the outer side of a vehicle.

  In other words, as shown in FIG. 6 (b), if it is the base panel 100 where the restriction wall (25) is omitted, the upper part is opened in the range between the base panel 100 and the guide block 50 of the arrow shown. As a result, the movement of the guide convex portion 42 entering the space S may be disordered, and the center panel 13 may come out of the vehicle.

  In addition, while the guide convex part 42 is located in the rail part 15a, possibility that the guide convex part 42 destroys the metal rail part 15a is low. Therefore, the guide convex portion 42 is restricted by the rail portion 15a, and the possibility of the center panel 13 coming out of the vehicle is low.

  In addition, when the center panel 13 is in the fully closed state or in the tilt up state, the guide convex portion 42 is positioned at the front end (lower end) of the guide portion 52, whereby both support brackets 40 (guide convex portion 42) are both guide rails. The possibility of falling off from 15 is low.

The effects of this embodiment will be described.
(1) In the present embodiment, it is possible to suppress the center panel 13 in the open state (pop-up state) at the time of a collision from coming out of the vehicle.

(2) In the present embodiment, the restriction wall 25 is integrally provided on the base panel 20 (the front frame 22), whereby the number of parts and the cost can be reduced.
The present embodiment can be modified as follows. The present embodiment and the following modifications can be implemented in combination with one another as long as there is no technical contradiction.
